ObjectiveTo investigate the expression of Lgr5 protein in regeneration tissue of remnant liver after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) and its significance.MethodsA total of 120 male SD rats (200–240 g) were randomly equally divided into sham operation (SO) group, portal vein ligation (PVL) group, and ALPPS group using random number table method. The liver regeneration rate (LRR), liver function (AST and ALT), and the expressions of Ki-67 and Lgr5 in the right middle lobe of the liver were observed at day 1, 2, 4, and 7 after surgery.ResultsCompared with SO group, the LRRs and the Ki-67 protein expression positive rates and Lgr5 related protein expression levels in the right middle lobe of liver tissue were increased in the PVL group and ALPPS group at day 1, 2, and 4 after surgery (P<0.05), and the LRR was still increased at day 7 after surgery (P<0.05). The LRRs at day 4 and 7 after surgery in the ALPPS group were higher than those in the PVL group (P<0.05), the Ki-67 protein expression positive rates and Lgr5 related protein expression levels at day 2 and 4 after surgery in the ALPPS group were higher than those in the PVL group (P<0.05). The AST and ALT levels at day 1 and 2 after surgery in the ALPPS group and PVL group were higher than those in the SO group (P<0.05), which at day 1 after surgery in the ALPPS group were higher than those in the PVL group (P<0.05), but which returned to normal on day 4 after surgery.ConclusionsALPPS could promote liver regeneration better. Lgr5 is closely related to liver regeneration after ALPPS. Liver stem cells might be involved in liver regeneration after ALPPS.
Objective
To compare therapeutic effects of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) and transcatheter arterial chemoembolization (TACE) on patients with advanced hepatocellular carcinoma.
Methods
Thirty-five patients with advanced hepatocellular carcinoma admitted in the Department of Hepatobiliary and Pancreatic Surgery of Shiyan Taihe Hospital Affiliated to Hubei University of Medicine from August 1, 2014 to August 1, 2015 were randomly divided into ALPPS group and TACE group, in which 17 cases treated by the ALPPS and 18 cases treated by the TACE. The survival, changes of liver function and life quality, postoperative complications and mortality were compared in these two groups. The follow-up was performed by the telephone and the outpatient.
Results
① The baselines such as the age, gender, diameter of tumor, complications had no significant differences in these two groups (P>0.05). ② The changes of liver function and life quality after operation in the ALPPS group were significantly better than those in the TACE group (P<0.05). ③ The complications after operation were observed in 5 cases (there were 2 cases of bile leakage, 1 case of intraabdominal bleeding, 1 case of peritoneal effusion, and 1 case of pulmonary infection) in the ALPPS group, which in 13 cases (there were 6 cases of nausea and vomiting, 4 cases of liver function damage, 2 cases of granulocytopenia, 1 case of fever) in the TACE group. The rate of the overall complications in the ALPPS group was significantly lower than that in the TACE group (5/17versus 13/18, P=0.018). ④ The overall survival in the the ALPPS group was significantly better than that in the TACE group (P=0.024). During follow-up period, the deaths happened in 3 cases duo to hepatocellular carcinoma and 1 case duo to traffic accident, 1 case was lost on month 8, 12 cases were still alive in the ALPPS group; the deaths happened in 10 cases duo to hepatocellular carcinoma, 1 case duo to coronary disease, and 1 case duo to cerebral infarction, 6 cases were still alive in the TACE group.
Conclusion
Preliminary results of limited cases in this study show that ALPPS has a better effect than TACE on patients with advanced hepatocellular carcinoma.
ObjectiveTo summarize experiences of diagnosis and treatment of intraperitoneal mass after associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) in treatment of hepatocellular carcinoma (HCC).MethodThe clinicopathologic data of a 40 years old case of HCC with intraperitoneal mass after ALPPS in the First Affiliated Hospital of Guangxi Medical University were retrospectively analyzed.ResultsThe patient was admitted to this hospital because of abdominal pain and abdominal distension for 5 d. The intraperitoneal mass was found and its nature was not clear on year 1 after ALPPS on admission. After discussion of multidisciplinary team (MDT), the exploratory laparotomy and abdominal tumor resection were planned to perform. The intraperitoneal mass and appendix were removed, the resected tissues were diagnosed as chronic inflammation and retroperitoneal abscess caused by perforation of suppurative appendicitis, respectively. The anti-infection and symptomatic support treatment were strengthened to perform after operation, the patient discharged after recovery. The patient was followed up so far, the general condition was good, and there was no clinical recurrence.ConclusionsFor patient underwent ALPPS, regular follow-up should be paid attention to. If intraperitoneal mass is found and nature is not clear, MDT discussion should be performed so as to make a more reasonable treatment plan. After exclusion of contraindications, surgical treatment should be carried out to furthest benefit patients.
Objective
To explore the effectiveness of staged treatment of open Pilon fracture combined with soft tissue defect.
Methods
Between June 2007 and December 2012, 18 cases of open Pilon fracture combined with soft tissue defect were treated. There were 14 males and 4 females with an average age of 35 years (range, 19-55 years). The causes of injury included falling from height in 12 cases, traffic accident in 4 cases, and crushing by machine in 2 cases. According to AO classification, 1 case was classified as type B2 fracture, 3 cases as type B3 fracture, 5 cases as type C1 fracture, 5 cases as type C2 fracture, and 4 cases as type C3 fracture. Sixteen cases accompanied by fibular fracture (14 cases of simple fibular fracture and 2 cases of communicated fibular fracture). According to Gustilo classification, the soft tissue injuries were all type IIIB. In first stage, debridement and vaccum sealing drainage combined with external fixation were performed; open reduction and internal fixation of simple fibular fracture were used. In second stage, open reduction and internal fixation of Pilon fracture and communicated fibular fracture were performed, and the flaps of 6 cm × 5 cm to 18 cm × 14 cm were applied to repair soft tissue defect at the same time. The donor site was repaired by skin graft.
Results
Partial necrosis occurred in 2 flaps, the other 16 flaps survived completely. The incisions of donor sites healed by first intention, the skin graft survived completely. The average follow-up interval was 12 months (range, 6-24 months). The X-ray films showed that the bone healing time ranged from 5 to 8 months (mean, 6 months). No internal fixation failure was found. At last follow-up, the average range of motion of the ankle joint was 37° (range, 26-57°). According to the American Orthopedic Foot and Ankle Society (AOFAS) scale, the average score was 80.2 (range, 72-86). Traumatic arthritis occurred in 2 cases (11%).
Conclusion
The staged treatment has the advantages of accurate evaluation of soft tissue injury, shortened cure time, good reduction of the articular surface, and reduced incidence of infection, so it is an optimal method to treat open Pilon fracture combined with soft tissue defect.
Objective To discuss the epidemiological characteristics of young and middle-aged people infected with COVID-19 in Gansu province under the new epidemic policy. Methods A total of 1800 people were collected from two tertiary hospitals in Gansu province from November 8, 2022 to January 28, 2023. The vaccination status, nucleic acid antigen detection, the specific time of infection, main symptoms and severity of the disease were investigated. Results Among 1800 participants, 1685 (93.6%) were vaccinated and 1565 (86.9%) were infected with COVID-19. Among the 1565 infected persons, 523 (33.4%) completed both nucleic acid and antigen testing, 382 (24.4%) completed nucleic acid testing, 490 (31.3%) completed antigen testing, 170 (10.9%) received IgG testing. 1490 (95.2%) were slight ill, 75 (4.8%) were critical ill, and 96 (6.1%) were hospitalized, and no one died. In 2022, 92 cases (5.9%) were infected in the first half of November, 141 cases (9.1%) in the second half of November, 630 cases (40.3%) in the first half of December, and 553 cases (35.4%) in the second half of December. 109 cases (7.0%) were infected in the first half of January, 38 cases (2.2%) in the second half of January, and 2 cases (0.1%) in the first half of February of 2023. and no cases in the second half of February. Among the 1565 infected persons, 825 (52.7%) had respiratory symptoms, 293 (18.7%) had gastrointestinal symptoms, 257 (16.4%) had autonomic disorders, 140 (8.9%) had other symptoms such as decreased smell and taste, and 48 (3.3%) had no symptoms after infection. Conclusions The vaccination rate of young and middle-aged people in Lanzhou city of Gansu Province is high. Since the new policy, the infection rate of the novel coronavirus among young and middle-aged people is high, the number of antigen tests is more than nucleic acid tests, most of the infected patients are slight, with fewer critical patients, and the hospitalization rate is low. The peak of infection occurred in early December 2022, and the infection rate was basically zero by February 2023. The main symptoms of COVID-19 infection are mainly respiratory tract, followed by digestive tract and autonomic nervous system disorders, and few patients are completely asymptomatic.
ObjectiveTo evaluate the effectiveness and safety of associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) combined with laparoscopic-assisted microwave ablation (Lap-MWA) for the liver resection in the treatment of unresectable primary hepatic carcinoma. Methods This study analyzed the clinical data of 12 hepatic carcinoma patients who underwent ALPPS combined with Lap-MWA for the liver resection from January 2019 to June 2021 in the Department of Hepato-Pancreato-Biliary Surgery of Qinzhou First People’s Hospital. The patients had insufficient future liver remnant (FLR) and different degrees of liver cirrhosis. The 1-stage ALPPS was to perform after the laparoscopic-assisted ligation of the portal vein of the loaded tumor. At the same time, the microwave ablation was used for the liver parenchyma segmentation under the guidance of laparoscopic ultrasound (LUS) without separating liver parenchyma. Other steps were the same as classic ALPPS. Results All the 12 patients successfully completed the operation. The 1-stage ALPPS lasted 90–130 min, (110.25±35.34) min; the blood loss was 80–140 mL, (100.37±42.24) mL. The interval between 2 stages was 12–16 d, (14.0±2.5) d. The FLR/standard liver volume (SLV) increased to (58.00±3.30) %. The 2-stage ALPPS lasted 120–180 min, (150±30) min; the blood loss was 300–1 200 mL, (453.50±107.70) mL; the hospital stay after 2 stages of ALPPS operations was 11–16 d, (14±2) d. Among all patients, 4 U of leukocyte suspension was transfused in 1 patient, and pleural ascites occurred in 3 patients. There were no serious complications such as liver failure and severe infection, and no death cases. The total hospital stay was 14–22 d, (17±3) d. After the 1-stage ALPPS, the total bilirubin, white blood cells, glutamic-pyruvic transaminase level increased (P＜0.05), and total bilirubin and white blood cells gradually returned to the normal level on the 5th day after 1-stage ALPPS. On the 1st day after finishing the 2-stage ALPPS, albumin and hemoglobin decreased, while white blood cells, total bilirubin, prothrombin time and glutamic-pyruvic transaminase increased in varying degrees (P<0.05). And on the 5th day after the 2-stage ALPPS, all indicators gradually returned to normal. All the patients were followed up for 6–30 months, (20±6) months. Two patients died of tumor recurrence and metastasis at 6.2 months and 13 months after the surgery, respectively. No recurrence was found in other patients, and their life quality was good. Conclusion Preliminary results of this study indicate that ALPPS combined with Lap-MWA is safe and effective for the treatment of unresectable primary hepatic carcinoma.
ObjectiveTo systematically review the prevalence of osteoarthritis in Chinese aged 40 and above from January 2000 to December 2019.MethodsPubMed, ScienceDirect, Wiley Online Library, The Cochrane Library, CBM, VIP, CNKI and WanFang Data databases were electronically searched to collect cross-sectional studies on osteoarthritis in Chinese aged 40 and above from January 1st, 2000 to December 31st, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed using R 3.5.2 software.ResultsA total of 29 cross-sectional studies with a total sample of 60 711 cases and 19 707 patients were included. The results of meta-analysis showed that, the crude prevalence of osteoarthritis in Chinese aged 40 and over was 38.46% (95%CI 24.31% to 46.22%). Subgroup analysis results showed that the prevalence of lumbar osteoarthritis was the highest (24.79%, 95%CI 13.28% to 27.37%), followed by knee osteoarthritis prevalence (20.50%, 95%CI 14.51% to 27.23%) which increased with age. The prevalence of knee osteoarthritis in females (25.14%, 95%CI 19.54% to 31.19%) was higher than that in males (18.99%, 95%CI 13.86% to 24.71%). The prevalence of knee and lumbar osteoarthritis in rural areas was higher than that in urban areas. The prevalence of knee osteoarthritis in western China (23.59%, 95%CI 18.34% to 30.35%) was higher than that in eastern China (18.36%, 95%CI 12.43% to 27.92%) and central China (15.54%, 95%CI 11.22% to 21.53%). The prevalence of lumbar osteoarthritis in western China (31.17%, 95%CI 19.21% to 50.60%) was higher than that in eastern China (24.38%, 95%CI 16.26% to 36.54%). The incidence of cervical osteoarthritis in the eastern China (20.49%, 95%CI 13.90% to 30.21%) was higher than that in the western China (12.32% 95%CI 8.09% to 18.75%). The prevalence of hand osteoarthritis in western China (6.85%, 95%CI 2.71% to 8.13%) was higher than that in eastern China (2.7%, 95%CI 1.33% to 5.48%).ConclusionsCurrent evidence shows that the prevalence of osteoarthritis in Chinese aged 40 and above is high, and the prevalence of lumbar osteoarthritis is the highest, and the prevalence in western China is higher than that in eastern and central China, followed by knee osteoarthritis, in which the prevalence in females, rural areas, and western China is high. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusion.
ObjectiveTo analyze the clinical effects of staged repair for severe tetralogy of Fallot (TOF), and to investigate a better individual treatment of TOF.
MethodsWe retrospectively analyzed the clinical data of 110 children with TOF in our hospital from January 2009 through December 2014. The patients were divided into a severe TOF group (Group A, n=23) and a mild TOF group (Group B, n=87). In the group A, all 23 patients underwent staged surgery (modified Blalock-Taussig and radical operation of TOF). In the Group B, all 87 patients only received a radical operation of TOF. The patients' preoperative and postoperative arterial oxygen saturation, McGoon ratio, left ventricular end-diastolic volume index (LVEDVI), the results of perioperation and follow-up were compared.
ResultsIn the group A, there was no death after modified Blalock-Taussig (MBT). The median interval time between MBTs and radical operation was 9 months (ranged from 6.3 to 25.3 months). Compared with that before MBTs, the McGoon ratio and LVEDVI were significantly increased at the time of radical operation. And the pulmonary artery development and left ventricle volume reached the standard of radical operation of TOF (P < 0.01). After the radical operation, one patient died for pneumonia in the early postoperation period. In the group B, three patients died for low cardiac output syndrome during perioperation. There was no significant difference between the group A and the group B in in-hospital mortality, length of hospital stay, intensive care unit (ICU) stay, ventilation time, cardiopulmonary bypass time, aortic cross-clamp time, rate of using trans-annular repair path, or drainage of pleural fluid.
ConclusionStaged repair of severe TOF is safe and effective for children, who are not suitable for one-stage radical operation. Severe TOF received staged repair can achieve the similar outcomes with that of mild TOF underwent one-stage radical operation.
ObjectiveTo analyze the quality of the randomized controlled trials (RCTs) included in the systematic review in the anti-infection field in the elderly.MethodsA comprehensive and systematic literature search in PubMed, EMbase, CNKI, The Cochrane Library, WanFang Data, VIP and CBM was conducted to collect systematic review or meta-analysis which involoved anti-infection RCTs in the elderly from inception to February 17th, 2020. The results of Cochrane risk of bias assessment of the included RCTs were analyzed.ResultsA total of 8 systematic reviews were included, involving 19 RCTs and 6 735 participants. The sample size of the RCTs ranged from 23 to 2538, and the published date were from 1980 to 2020. The included RCTs focused on postoperative infection, urinary tract infection, Clostridium Difficile infection and so on. The included RCTs had methodological quality issues. Among the assessment results of low risk of bias, the domains of selection bias (random sequence generation) and selection bias (allocation hiding) had the lowest proportion (47.3%, 36.8%). Among the assessment results of unclear risk of bias, the domains of selection bias (random sequence generation) and selection bias (allocation hiding) had the highest proportion (42.1%, 52.6%). Among the assessment results of high risk of bias, the domains of measurement bias and performance bias had the highest proportion (21.1%, 21.1%).ConclusionsThe quality of RCTs in the field of anti-infection in the elderly requires further improvement. High-quality anti-infection RCTs for the elderly should be developed in future to better guide clinical practice.
ObjectiveTo compare the complications and clinical scores of posterior lumbar intervertebral fusion (PLIF) in middle-aged and older patients of different ages, and to assess the risk of complications of PLIF in different ages, providing a reference for clinical treatment.MethodsThe clinical data of 1 136 patients, who were more than 55 years old and underwent PLIF between June 2013 and June 2016, were retrospectively analyzed. According to the age of patients undergoing surgery, they were divided into 3 groups as 55-64 years old, 65-74 years old, and ≥75 years old. The general characteristics, comorbidities, and surgical data of the three groups were compared, with comparison the morbidity of complications. According to the minimal clinical important difference (MCID), the improvement of patient’s pain visual analogue scale (VAS) score and the Oswestry disability index (ODI) score were compared. Univariate logistic regression analysis was used to analyze the difference of complications and the improvement of VAS and ODI scores. Multivariate logistic regression analysis was performed for the risk factors of complications.ResultsThere were significant differences in the number of surgical fusion segments and osteoporosis between groups (P<0.05); there was no significant difference in gender, body mass index, operation time, preoperative American Society of Anesthesiologists (ASA) classification, and comorbidities between groups (P>0.05). All patients were followed up 6-62 months with an average of 27.4 months. Among the results of postoperative complications, there were significant differences in the total incidence of intraoperative complications, systemic complications, minor complications, and the percentage of improvement of ODI score to MCID between groups (P<0.05); but there was no significant difference in the total incidence of complications at the end of long-term follow-up and the percentage of improvement of VAS score to MCID between groups (P>0.05). Univariate logistic regression analysis showed that after adjusting the confounding factors, there were significant differences in intraoperative complications and the percentage of improvement of ODI score to MCID between 55-64 and 65-74 years old groups (P<0.05); systemic complications, minor complications, complications at the end of long-term follow-up, and the percentage of improvement of ODI score to MCID in ≥75 years old group were significantly different from those in the other two groups (P<0.05). Multivariate logistic regression analysis showed that age was a risk factor for systemic complications, minor complications, and complications at the end of long-term follow-up. Except for age, long operation time was a risk factor for intraoperative complications, increased number of fusion segments was a risk factor for systemic complications, the number of comorbidities was a risk factor for minor complications, and osteoporosis was a risk factor for complications at the end of long-term follow-up.ConclusionThe risk of surgical complications is higher in the elderly patients (≥75 years) with lumbar degenerative diseases than in the middle-aged and older patients (<75 years), while the improvements of postoperative VAS and ODI scores were similar. Under the premise of fully assessing surgical indications, PLIF has a positive effect on improving the elderly patients’ quality of life.
