ObjectiveIn light of the comprehensively implemented reform of medical insurance payments, this study analyzed the impact of the payment intervention and COVID-19 pandemic on hospitalization expenses for identical diseases between traditional Chinese medicine (TCM) and Western medicine hospitals, to provide evidence to promote high-quality coordinated development of hospitals and insurance while reducing patient load. MethodsFrom January 2014 to December 2020, we gathered data including 9 900 individual medical records of woman-related malignant tumors (WMT) from all 23 public hospitals in a district of Shanghai. We developed an interrupted time-series analysis model based on the above two interventions, to compare the inpatient average per-time expenses between different hospitals and different groups. ResultsThe average per-time expenses of WMT in Western hospitals changed from rising to declining after the policy intervention, and increased again during the pandemic. In TCM hospitals, the expenses continued to increase and fluctuated after the pandemic. ConclusionThe policy intervention has achieved a good effect on controlling the cost of Western hospitals, rather than the significant increase in TCM hospitals. Meanwhile, the COVID-19 pandemic has had a significant impact on hospitalization expenses. It’s urgent to develop a payment model that fits the development and characteristics of TCM, to control the unreasonable growth of expenses. Moreover, the financial compensation methods and supervision mechanism of public hospitals should be improved to effectively resist the threat of public health emergencies for the development of hospitals and the legitimate rights of patients.
Pre-and postoperative perfusion of thermochemotherapy was used in 25 cases of advanced malignant tumors of digestive tract.There were on significant changes in hepatic and renal functions after perfusions.The erythrocyte,leukocyte and platelet counts reduced in the second and third week after the beginningof perfusion,but rose up in the 4th week.A 2-year follow-up revealed that 23 patients were still alive without recurrence or metastases except 2cases died in the 6th and the 9th month after treatment.We claim that intraperitoneal thermochemotherapy is a simple and safe method. A prospective study is still necessaryin deciding the dose and course.
Objective To estimate the clinical curative effect of replacement of inverttype artificial total scapula and shoulder joint prosthesis and reserving arm with rehabilitation of function in the treatment of malignant tumor in shoulder. Methods From February 2001 and November 2004, five youth patients with primary malignant shoulder tumors were treated operatively by resection of neoplasmsthoroughly, replacement of inverttype artificial total shoulder blade and joint prosthesis, the functional reconstruction. Of them, there were 4 males and 1 female, aging from 19 to 26 years with an average of 23.6 years. Two cases were diagnosed as having osteosarcoma, one as having chondrosarcoma, and 2 as having Ewing sarcoma. After operation, the upper limbs was immobilized for 3 weeks. The rehabilitation training including passive exercise and initiative exercise. Results The average operative time was 425 min (380 to 530 min), and the blood loss ranged from 1 250 ml to1 900 ml(1 540 ml on average). The follow-up ranged from 7 to52 onths,with an average of 24.6 months. Postoperative complication included 1 case of pneumothorax, one case of shoulder incision skin part necrosis and 1 case of clavicle stump raising and pierce skin with shallow infection. No complication of postoperative incision deeply infection, nerve damage and prosthesis exposure or dislocation occurred. According to the scoring system of JOA(Japan orthopaedics association), the average score was 65 (60 to 72). The flexion and extension function of elbow joint recovered to normal. Conclusion The replacement of inverttype artificial total scapula and shoulder joint prosthesis is an efficacious method for the treatment of malignant tumor in shoulder. There are advantages of numerous adaption, wide range of motion and goodstability. It can not only reserve arm but also rehabilitate function.
Objective To explore the design points of a three-dimensional (3D) printed customized cementless intercalary endoprosthesis with an intra-neck curved stem and to evaluate the key points and mid-term effectiveness of its application in the reconstruction of ultrashort bone segments in the proximal femur. Methods Between October 2015 and January 2021, 17 patients underwent reconstruction with a 3D printed-customized cementless intercalary endoprosthesis with an intra-neck curved stem. There were 11 males and 6 females, the age ranged from 10 to 76 years, with an average of 30.1 years. There were 9 cases of osteosarcoma, 4 cases of Ewing sarcoma, 2 cases of chondrosarcoma, 1 case of liposarcoma, and 1 case of myofibroblastoma. The disease duration was 5-14 months, with an average of 9.5 months. Enneking staging included 16 cases of stage ⅡB and 1 case of stage ⅢB. The distances from the center of the femoral head to the body midline and the acetabular apex were measured preoperatively on X-ray images. Additionally, the distances from the tip of the intra-neck curved stem to the body midline and the acetabular apex were measured at immediate postoperatively and last follow-up. The neck-shaft angle was also measured preoperatively, at immediate postoperatively, and at last follow-up. The status of osseointegration at the bone-prosthesis interface and bone growth into the prosthesis surface were assessed by X-ray films, CT, and Tomosynthesis-Shimadzu metal artefact reduction technology (T-SMART). The survival status of the patients, presence of local recurrence or distant metastasis, and occurrence of postoperative complications were assessed. The recovery of lower limb function was evaluated pre- and post-operatively using the Musculoskeletal Tumor Society (MSTS) scoring system, and pain relief was evaluated using the visual analogue scale (VAS) scores. Results The patient’s femoral resection length was (163.1±57.5) mm, the remaining proximal femoral length was (69.6±9.3) mm, and the percentage of femoral resection length/total femoral length was 38.7%±14.6%. All 17 patients were followed up 25-86 months with an average of 58.1 months. During the follow-up, 1 patient died of lung metastasis at 46 months postoperatively, and the remaining 16 patients survived tumor-free. There was no complication such as periprosthetic infection, delayed incision healing, aseptic loosening, prosthesis fracture, or periprosthetic fracture. No evidence of micromotion or wear around the implanted stem of the prosthesis was detected in X-ray and T-SMART evaluations. There was no significant radiolucent lines, and radiographic evidence of bone ingrowth into the bone-prosthesis interface was observed in all stems. There was no significant difference in the distance from the tip of the curved stem to the body midline and the apex of the acetabulum at immediate postoperatively and last follow-up compared with the distance from the center of the femoral head to the body midline and the apex of the acetabulum before operation, respectively (P>0.05), and there was no significant difference in the above indexes between immediate postoperatively and last follow-up (P>0.05). The differences in the neck-shaft angle at various time points before and after operation were also not significant (P>0.05). At last follow-up, the MSTS score was 26.1±1.2 and the VAS score was 0.1±0.5, which were significantly improved when compared with those before operation [19.4±2.1 and 5.7±1.0, respectively] (t=14.735, P<0.001; t=21.301, P<0.001). At last follow-up, none of the patients walked with the aid of crutches or other walkers. Conclusion The 3D printed customized cementless intercalary endoprosthesis with an intra-neck curved stem is an effective method for reconstructing ultrashort bone segments in the proximal femur following malignant tumor resection. The operation is reliable, the postoperative lower limb function is satisfactory, and the incidence of complications is low.
ObjectiveTo investigate the procedure and effectiveness of total femoral replacement for treating femur malignant tumor.MethodsThe clinical data of 9 patients with femoral malignant tumors who underwent total femoral replacement between July 2013 and March 2017 were retrospectively analyzed. There were 5 males and 4 females, aged 16-75 years with an average of 44.8 years. The disease duration ranged from 2 to 6 months with an average of 3.5 months. There were 5 cases of osteosarcoma (3 cases were staged as Enneking ⅡB, 2 cases were staged as Enneking Ⅲ), 1 case of malignant fibrosarcoma (staged as Enneking ⅡB), 1 case of chondrosarcoma (staged as Enneking ⅠB), 2 cases of femoral muti-metastasis of lung cancer with pathological fracture. The visual analogue scale (VAS) score and the quality of life (QOL) score of the tumor patients were evaluated before operation and at 3 months after operation. The Musculoskeletal Tumor Society (MSTS) score and Harris hip score (HHS) were evaluated at last follow-up.ResultsNine patients were followed up 11-58 months, with an average of 21 months. No complication such as wound infection, joint dislocation, and nerve injury occurred. One patient developed popliteal vein thrombosis, and 2 patients with osteosarcoma died of tumor progression. The VAS score and QOL score at 3 months after operation were 3.2±1.2 and 40.6±5.4 respectively, which were significantly improved when compared with preoperative ones (5.9±0.8 and 22.3±4.2 respectively) (t=11.314, P=0.000; t=–7.794, P=0.000). At last follow-up, the MSTS score was 15-29 with an average of 21.1, and the HHS score was 44-90 with an average of 66.5.ConclusionTotal femoral replacement is an effective limb salvage procedure for the treatment of femoral malignant tumors, which can effectively restore the weight-bearing and walking function, relieve pain, and improve the quality of life.
ObjectiveTo investigate the experience in the treatment of splnic malignant tumors with laparoscopy.
MethodsThe clinical data of 51 patients with splnic malignant tumor who underwent splenectomy between January 2009 and July 2015 were retrospectively reviewed. Patients were divided into two groups based on the surgical method: Open splenectomy (OS group, n=18) and laparoscopic splenectomy (LS group, n=33). The preoperative, intraoperative and postoperative data of the patients were collected and analysed, the differences of each index during perioperative period (general information), intraoperative data (operative time, estimated blood loss, the size of spleen, intraoperaive transfusion) and postoprative situation (hospital stays, the first oral intake, postoperative pancreatic fistula, rehaemorrhagia, abdominal infection or pulmonary infection and the like) were compared.
ResultsLS group compared with OS group, the operative time of LS group was significantly shorter than that of OS group [(103.64±16.92) min vs. (144.44±31.10) min, P=0.000〕, the amount of bleeding of LS group [M (Q25, Q75): 60 (50, 100)〕was significantly less than the OS group [M (Q25, Q75): 150 (115, 210)〕, P=0.000. The hospitalization time of LS group was significantly shorter than the OS group [(13.61±9.91) d vs. (9.03±3.09) d, P=0.017〕, and the LS group has a lower indication of the postoprative complications of fever and pulmonary infection (P=0.010 and P=0.003). Conciusions Laparoscopic splenectomy is feasible in the treatment of splenic malignant tumors, the employment of laparoscopy can shorten the operative time, has the advantages of less bleeding, the shorten hospital stays, lower indication of postoprative complications, and being worthy of further popularization and application.
Transcription factor p63 originates from p53 protein family and is encoded by TP63 gene. TP63 gene contains two different promoters encoding two proteins, TAp63 and ΔNp63, which can be cleaved to produce p63α, p63β, p63δ and some other subtypes. ΔNp63α is one of the promoters of TP63 gene and acts as a core regulatory factor to regulate gene expression at epigenetic and transcriptional levels. Recent research shows that ΔNp63α abnormal expression can lead to the occurrence of various malignant tumors and reduce the sensitivity of malignant tumors to radiotherapy and chemotherapy. Therefore, ΔNp63α can be used as a diagnostic marker and therapeutic target for malignant tumors. This article reviews the latest research progress of ΔNp63α in the mechanism and drug resistance in malignant tumors.
ObjectiveTo summarize the experience in the treatment of infection after limb salvage surgery for malignant tumor around knee joint, and explore the risk factor related to infection after limb salvage surgery.MethodsA clinical data of 212 patients with malignant tumor around the knee joint underwent limb salvage surgery between January 2008 and December 2017 were retrospectively analyzed. Among them, 14 cases had infection after limb salvage surgery. Two cases of acute infection were treated with sensitive antibiotics; 12 cases of chronic infection were treated with debridement and antibiotic bone cement occupying device implantation in the first stage, and prosthesis revision (8 cases), knee joint fusion (2 cases), or amputation (2 cases) in the second stage after infection control. The age, gender, preoperative chemotherapy cycle, bone marrow suppression, serum albumin, hemoglobin, operation time, postoperative drainage time, and blood transfusion volume were analyzed to screen the risk factors related to infection after limb salvage surgery. The infection and tumor recurrence were observed, and the limb function was evaluated by Enneking scoring system.ResultsThe univariate analysis showed that the preoperative chemotherapy cycle, bone marrow suppression, operation time, and postoperative drainage time were the influencing factors of postoperative infection (P<0.05). Multivariate analysis showed that the operation time, preoperative chemotherapy cycle, and postoperative drainage time were risk factors of postoperative infection (P<0.05). Among the 14 patients, 1 patient died of traffic accident at 6 months after the second stage operation, and 13 patients were followed up 12.2-48.0 months (mean, 19.9 months). Two cases of acute infection cured. Among the 11 patients with chronic infection, 2 cases of subluxation of the antibiotic bone cement occupying device after the first stage operation occurred; 9 cases of infection cured and 2 cases recurred. At 12 months after operation, except 1 case died by accident, the Enneking scores of the other 13 patients were 12-26, with an average of 20. At last follow-up, 1 case of lung metastasis was still alive, and no tumor metastasis or recurrence was found in the rest.ConclusionThe time of limb salvage surgery, preoperative chemotherapy cycle, and drainage time after limb salvage surgery are the risk factors of infection after limb salvage surgery. Early etiological examination and drug sensitivity test is the key to the treatment of infection. One-stage debridement combined with antibiotic bone cement occupying device can effectively cure infection and save patients’ limbs.

Most of the patients are middle-aged and young people, who have thirst for high quality of life in long-term. Pancreatic-duct-preserving partial pancreatectomy can meet the needs of reducing surgical trauma, preserving normal pancreatic function and improving patients’ quality of life. However, pancreatic-duct-preserving partial pancreatectomy often needs to face the problem of pancreatic duct defect. Repair of pancreatic duct needs to be applied ? according to different types of pancreatic duct defect. At the same time, the prevention and treatment of pancreatic fistula also require more patience, courage and creativity of pancreatic surgeons. Pancreatic-duct-preserving partial pancreatectomy can solve the current clinical problems. It is safe and feasible with carefully evaluate indications, characters of patients and the personal ability of surgeons.
ObjectiveTo investigate the effectiveness of different free flaps in the repair of large defects after resection of scalp malignant tumors.
MethodBetween March 2012 and January 2015, 18 patients with large defect after resection of scalp malignant tumors were treated with different free flaps. There were 13 males and 5 females with an average age of 49 years (range, 18-72 years). There were 17 cases of squamous carcinoma and 1 case of dermato-fibril sarcoma protuberans. The defect size ranged from 15 cm×12 cm to 22 cm×17 cm after resection of tumors. Defects were repaired with anterolateral thigh flap in 5 cases, latissimus dorsi myocutaneous flap in 6 cases, thoracodorsal artery perforator flap in 3 cases, and latissimusdorsi muscle flap plus intermediate split thickness skin graft in 4 cases. The flap size was 17 cm×14 cm to 24 cm×19 cm. The donor sites of the skin flap were covered with skin graft, while the donor sites of the muscle flap were directly sutured.
ResultsOf 14 skin flaps, the other 13 flaps survived except 1 flap necrosis; all muscle flaps survived. The patients were followed up 5-33 months (mean, 20 months). Three patients died because of intracranial metastasis at 5, 7, and 13 months after operation, respectively. Two patients had local recurrence and underwent secondary operation. The results of both appearance and function were satisfactory; secondary operation of thinning the flaps was performed in 4 cases of bulky flaps. The flaps had good wear resistance, without ulceration during follow-up. No obvious impairment was observed after harvesting latissimus dorsi myocutaneous flap.
ConclusionsLarge scalp defects after malignant tumor resection can be effectively repaired by proper application of different free flaps.
