Objective To investigate the effectiveness of sequential plate internal fixation in the correction of Madelung deformity after ulnar osteotomy and shortening. Methods The clinical data of 13 patients with Madelung deformity admitted between September 2015 and July 2021 were retrospectively analyzed. There were 5 males and 8 females with an average age of 18.3 years ranging from 17 to 23 years. The disease duration ranged from 12 to 24 months, with an average of 17 months. Three cases had a clear history of trauma. All patients had external radial deviation deformity and limited movement of the ulnar deviation, and the ulnar impact pain was significant during ulnar deviation movement; 9 patients had limited wrist joint supination movement, and the supination movement was normal. In the first stage, ulnar osteotomy and shortening combined with external fixator were used to correct wrist deformity in 13 patients. After operation, bone transfer was performed 6 times per day, with adjustments made every 4 hours, which was 1 mm per day. After the osteotomy was in place, the ulnar plate internal fixation was performed to reconstruct the ulnar stability in the second stage. The Cooney wrist joint score was used to assess the pain, function, range of motion, flexion and extension range of motion, and grip strength of the wrist joint before operation and before the removal of internal fixator. The subjective feeling and appearance satisfaction of patients were recorded. ResultsAfter the second-stage operation, all the 13 patients were followed up 10-22 months, with an average of 15 months. The deformity of wrist joint disappeared after operation, and the flexion, extension, and ulnar deviation were basically normal. There was no complication such as ulnar impingement sign, nonunion or infection. Wrist function, pain, and range of motion were significantly improved after operation, except for 1 patient who had no significant improvement in rotation and pain. The ulnar internal fixator was removed at 10-18 months after the second-stage operation. The scores of pain, function, range of motion, flexion and extension range of motion, and grip strength in the Cooney wrist score before removal of internal fixator significantly improved when compared with those before operation (P<0.05). Subjective and appearance satisfaction of patients were excellent in 9 cases, good in 3 cases, and fair in 1 case. ConclusionUlnar osteotomy and shortening with sequential plate internal fixation for correction of Madelung deformity, with mild postoperative pain, can effectively avoid bone nonunion, improve wrist joint function, and have significant effectiveness.
Objective To systematically evaluate the efficacy and safety of single and bilateral lung transplantation in the treatment of end-stage chronic obstructive pulmonary disease (COPD). Methods Chinese and English databases were searched by computer, including PubMed, Web of Science, The Cochrane Library, EMbase, CNKI, Wanfang database, VIP database and CBM. Case-control studies on single lung transplantation or bilateral lung transplantation for COPD were collected from the inception to July 31, 2022. We evaluated the quality of the literature via Newcastle-Ottawa Scale (NOS). All results were analyzed using Review Manager V5.3 and STATA 17.0. Results A total of 8 studies were included covering 14076 patients, including 8326 patients in the single lung transplantation group and 5750 patients in the bilateral lung transplantation group. NOS scores were≥6 points. The results of meta-analysis showed that there was no statistical difference in the postoperative 1-year survival between the two groups (P=0.070). The 2-year survival rate (P=0.002), 3-year survival rate (P<0.001), 5-year survival rate (P<0.001), overall survival rate (P＜0.001), postoperative forced expiratory volume in one second/predicted value (P<0.001), postoperative forced vital capacity (P<0.001), and postoperative 6-minute walking distance (P=0.002) were lower or shorter than those in the bilateral lung transplantation group, the postoperative intubation time (P=0.030) was longer than that in the bilateral lung transplantation group. Bilateral lung transplantation group showed better surgical results. There was no statistical difference in the mortality, obliterative bronchiolitis, length of hospitalization, primary graft dysfunction, or postoperative adverse events (P>0.05). Conclusion Bilateral lung transplantation is associated with better long-term survival and postoperative lung function compared with single lung transplantation. In-hospital mortality and postoperative complications are similar between them.
Objective To evaluate the efficacy of Gefitinib for patients with non-small-cell lung cancer (NSCLC). Methods We searched several databases, including MEDLINE (1991 to June 2008), The Cochrane Library (Issue 4, 2008) and CBMDisc (1978 to Feb. 2008). Randomized controlled trials (RCTs) were included in the meta-analyses, which were done using The Cochrane Collaboration’s RevMan 4.2 software. We also included retrospective case reports published in Chinese journals. Results Eight RCTs and 36 uncontrolled case reports were analyzed. The results of the RCTs showed that 250 mg/d Gefitinib had similar efficacy to 500 mg/d, but the side effect was significantly less for the lower dose. When used as a combined first-line treatment or a third-line treatment, Gefitinib was not superior to placebo on response rate, survival rate and life span. When used as second-line treatment, it did not prolong median survival, though it gave a higher response rate than placebo. Gefitinib caused many more side effects than placebo. Gefitinib exhibited similar efficacy to docetaxel in objective response rate [OR 1.18, 95%CI (0.84, 1.67), P=0.35], but was better for symptom and quality-of-life improvement [OR 1.58, 95%CI (1.33, 1.89), Plt;0.00001]. The overall uncontrolled clinical studies showed the following results: complete response rate was 2.2%, partial response rate was 25.8%, disease stable rate was 40.0% and progressive disease rate was 32.0%. The average median survival time was 8.9 months; the average time to progressive disease was 5.2 months, and the 1-year survival rate was 44.2%. The average median survival from EAP studies (6.9 months) was shorter than that for all the studies as well as the registered clinical trials (10.0 months). The average periods to progressive disease for registered clinical trials (3.2 months) and EAP studies (4.4 months) were somewhat shorter than that found for all studies combined, though response rate and 1-year survival rate were similar. Since there was no controlled clinical study, it was hard to conclude from the results whether Gefitinib brought any clinical benefit to NSCLC patients in China. Conclusion Gifitinib is not suitable as a combined first-line treatment or a third-line treatment for NSCLC. The clinical favor from gefitinib in the second-line treatment remains uncertain. There is not enough evidence to show whether Chinese people are more sensitive to Gefitinib, and its use in the second-line treatment of NSCLC needs to be tested further.
ObjectiveTo investigate the effects of robotic versus thoracoscopic lobectomy on body trauma and lymphocyte subsets in patients with non-small cell lung cancer (NSCLC).MethodsThe clinical data of 120 patients with NSCLC who underwent lobectomy in the same operation group at the same period were collected and divided into a robot group (n=60) and a thoracoscope group (n=60) according to different surgical methods. The operation time, intraoperative blood loss, postoperative drainage time, drainage volume, postoperative hospital stay, complication rate, pain visual analogue scale (VAS) and other perioperative indicators were recorded in the two groups. Inflammatory markers: C-reactive protein (CRP), interleukin-6 (IL-6) and lymphocyte subsets (CD3+, CD4+, CD8+, CD4+/CD8+) levels were measured before and 1 d, 3 d after surgery. The effects of the two surgical methods on the body trauma and lymphocyte subsets were compared.ResultsThe operation time, intraoperative blood loss, postoperative drainage time, drainage volume and VAS of the robot group were lower than those of the thoracoscope group, and the differences were statistically significant (P<0.05). On the 1st day after surgery, IL-6 of the thoracoscope group was higher than that of the robot group, while CD3+, CD4+ and CD8+ were lower than those of the robot group, with statistically significant differences (P<0.05).ConclusionCompared with thoracoscopic lobectomy, robotic lobectomy has less trauma, less inflammatory response, faster recovery, less inhibitory effect on lymphocyte subsets, and has clinical advantages.
Objective To investigate the pathogenesis of acute lung injury in rats induced by intra-peritoneally injection of perforative peritonitis ascitic fluids（PPAF） and the role of L-arginine （L-Arg） in acute lung injury in this model. Methods Perforative peritonitis （PP） models were established in 60 rats and PPAF were collected. Forty-eight rats were randomly divided equally into NS group，PPAF group, and L-Arg group. Rats were randomly subjected to death at 7 h and 12 h. Peripheral blood WBC were counted，levels of NO and malondialdehyde （MDA） in serum were examined. Lung injury score and wet/dry ratio were evaluated， and level of myeloperoxidase （MPO） in lung tissues and lung cell apoptosis were tested. Results WBC count of peripheral blood, levels of NO and MDA in serum， level of MPO in lung tissue, lung injury score， wet/dry ratio， and lung cell apoptosis rate in PPAF group were significantly higher than that in NS group at each time point（P＜0.01）. Level of NO in serum in L-Arg group was higher than that in PPAF group （P＜0.01）， but lower level of MDA in serum， lower level of MPO in lung tissue and lung injury score，lower wet/dry ratio， and lung cell apoptosis rate were observed in L-Arg group（P＜0.05）. In PPAF group and L-Arg group， level of NO in serum， wet/dry ratio, and lung cell apoptosis rate were higher at 12 h than that at 7 h（P=0.000）. Serum NO level was in negative correlation with serum MDA level （r=-0.257，P=0.021）， MPO level in lung tissue（r=-0.444， P=0.011），and lung cell apoptosis（r=-0.351， P =0.010） in PPAF group and L-Arg group， but serum MDA level was in positive correlation with cell apoptosis（r=0.969， P＜0.001） in each group. Conclusions Acute lung injury rats model can be established by intra-peritoneally injection of PPAF. Enhanced oxidizing reaction and cell apoptosis take part in the occurrence of acute lung injury. L-Arg plays a protective role in acute lung injury.
ObjectiveTo systematically review the efficacy and safety of crizotinib in the treatment of non-small cell lung cancer (NSCLC).MethodWe electronically searched databases including the Cochrane Library (Issue 5, 2017), PubMed, Embase, China Biology Medicine Database, China National Knowledge Internet Database, VIP Database and Wangfang Data from the establishment to May 2017. The randomized controlled trials (RCTs), non-RCTs, case series and case reports on crizotinib for NSCLC were included. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, assessed the methodological quality of included studies, then make Meta-analysis and descriptive analysis.ResultA total of 15 studies were included, including 4 RCTs, 1 non-RCT, 4 case series and 6 case reports. The results indicated that the progression-free survival time of crizotinib group was 8 months, which was better than chemotherapy group (4.6 months). The results of Meta-analysis showed that the response rate in the crizotinib group was higher than that in the chemotherapy group [RR=2.35, 95%CI (1.59, 3.46), P<0.000 1]. The one year survival rate in the crizotinib group was 74.5%-78.6%. The incidences of adverse reactions including dysopsia, dysgeusia, diarrhea, vomiting, constipation, transaminase lifts, upper respiratory tract infection, edema and dizziness in the crizotinib group were higher than those in the chemotherapy group (P<0.05), while the incidences of adverse reactions including leukopenia, thrombocytopenia, alopecia and fatigue in crizotinib group were lower than those in the chemotherapy group (P<0.05). Subgroup analysis under precision treatment showed the progression-free survival time of anaplastic lymphoma kinase (ALK)-positive group was 8 months, and it was longer than ALK-negative group of 4 months.ConclusionsBased on current evidence, crizotinib is better than chemotherapy for NSCLC. Due to limited quality of the included studies, the above conclusion needs to be verifed by more high quality studies.
Objective
To investigate the perioperative outcome of robot-assisted pulmonary lobectomy in treating pathological stage Ⅰ non-small cell lung cancer (NSCLC).
Methods
We retrospectively analyzed the clinical data of 333 consecutive p-T1 NSCLC patients who underwent robotic-assisted pulmonary lobectomy in our hospital between May 2013 and April 2016. There were 231 females (69.4%) and 102 males (30.6%) aged from 20–76 (55.01±10.46) years. Cancer was located in the left upper lobectomy in 37 (11.1%) patients, left lower lobectomy in 71 (21.3%) patients, right upper lobectomy in 105 (31.5%) patients, right middle lobectomy in 32 (9.6%) patients, right lower lobectomy in 88 (26.4%) patients. Adenocarcinoma was confirmed in 330 (99.1%) patients and squamous cell cancer was confirmed in 3 (0.9%) patients.
Results
Total operative time was 46–300 (91.51±30.80) min. Estimated intraoperative blood loss was 0–100 ml in 319 patients (95.8%), 101–400 ml in 12 patients (3.6%), >400 ml in 2 patients (0.6%). Four patients were converted to thoracotomy, including 2 patients due to pulmonary artery branch bleeding and 2 due to pleural adhesion.No patient died within 30 days after surgery. And no perioperative blood transfusion occurred. Postoperative day 1 drain was 0–960 (231.39±141.87) ml. Chest drain time was 2–12 (3.96±1.52) d.And no patient was discharged with chest tube. Length of hospital stay after surgery was 2–12 (4.96±1.51) d. Persistent air leak was in 12 patients over 7 days. No readmission happened within 30 days. All patients underwent lymph node sampling or dissection with 2–9 (5.69±1.46) groups and 3–21 (9.80±3.43) lymph nodes harvested. Total intraoperative cost was 60 389.66–134 401.65 (93 809.23±13 371.26) yuan.
Conclusion
Robot-assisted pulmonary lobectomy is safe and effective in treating p-Stage Ⅰ NSCLC, and could be an important supplement to conventional VATS. Regarding to cost, it is relatively more expensive compared with conventional VATS. RATS will be widely used and make a great change in pulmonary surgery with the progressive development of surgical robot.
ObjectiveTo investigate the effect of perioperative allogeneic blood transfusion on the prognosis of patients with non-small cell lung cancer (NSCLC).MethodsThe databases including PubMed, The Cochrane Library, EMbase, CNKI, Wanfang Data, VIP and CBM were searched for literature about the effects of perioperative allogeneic blood transfusion on the prognosis of patients with NSCLC from the inception to May 2020. Two authors independently screened the literature, extracted and cross-checked data, and negotiated to resolve differences in opinions. Review Manager V5.3 (Cochrane Collaboration, Oxford, UK) software was used for data analysis.ResultsA total of 15 articles were included, including 5 897 patients. There were 1 649 patients in the trial group and 4 248 patients in the control group. The results of meta-analysis showed that the overall survival of the control group was significantly higher than that of the trial group (OR=0.58, 95%CI 0.47-0.70, P<0.000 01). The disease-free survival of the control group was significantly higher than that of the trial group (OR=0.43, 95%CI 0.36-0.52, P<0.000 01). The recurrence rate of the control group was significantly lower than that of the trial group (OR=1.85, 95%CI 1.34-2.55, P=0.000 2).ConclusionPerioperative allogeneic blood transfusion has adverse effects on the recurrence and survival of patients with NSCLC.
ObjectiveTo explore the CT imaging features and independent risk factors for cystic pulmonary nodules and establish a malignant probability prediction model. Methods The patients with cystic pulmonary nodules admitted to the Department of Thoracic Surgery of the First People's Hospital of Neijiang from January 2017 to February 2022 were retrospectively enrolled. They were divided into a malignant group and a benign group according to the pathological results. The clinical data and preoperative chest CT imaging features of the two groups were collected, and the independent risk factors for malignant cystic pulmonary nodules were screened out by logistic regression analysis, so as to establish a prediction model for benign and malignant cystic pulmonary nodules. ResultsA total of 107 patients were enrolled. There were 76 patients in the malignant group, including 36 males and 40 females, with an average age of 59.65±11.74 years. There were 31 patients in the benign group, including 16 males and 15 females, with an average age of 58.96±13.91 years. Multivariate logistic analysis showed that the special CT imaging features such as cystic wall nodules [OR=3.538, 95%CI (1.231, 10.164), P=0.019], short burrs [OR=4.106, 95%CI (1.454, 11.598), P=0.008], cystic wall morphology [OR=6.978, 95%CI (2.374, 20.505), P<0.001], and the number of cysts [OR=4.179, 95%CI (1.438, 12.146), P=0.009] were independent risk factors for cystic lung cancer. A prediction model was established: P=ex/(1+ex), X=–2.453+1.264×cystic wall nodules+1.412×short burrs+1.943×cystic wall morphology+1.430×the number of cysts. The area under the receiver operating charateristic curve was 0.830, the sensitivity was 82.9%, and the specificity was 74.2%. ConclusionCystic wall nodules, short burrs, cystic wall morphology, and the number of cysts are the independent risk factors for cystic lung cancer, and the established prediction model can be used as a screening method for cystic pulmonary nodules.
Surgical management of non-small cell lung cancer (NSCLC) invading chest wall is the combination of pulmonary resection, lymphadenectomy and chest wall resection and reconstruction. Hitherto the surgical procedures include combination of thoracotomy and video-assisted thoracoscopic surgery (VATS), thoracotomy, and VATS. The result of the surgery leads to a defect in the chest wall. Therefore, the requirements of the technique and material are relatively high with no consensual standard. This review describes the definitions, indications, materials, prognostic factors, and recent progress in surgical techniques.
