Objective To evaluate the relationship between chemotherapy after pulmonary resection and the incidence rate of bron-chopleural fistula. Methods 246 patients who received pulmonary resection in our hospital from January 2009 to June 2014 were chosen, and they were divided into the chemotherapy group and the non-chemotherapy group. The 138 patients in the chemotherapy group received chemotherapy one month after resection while the other 108 in the non-chemotherapy group did not. Bronchopleural fistula of the two groups were diagnosed and analyzed in order to evaluate the relationship between chemotherapy after pulmonary resection and incidence rate of bron-chopleural fistula. Results There were 12 cases of bronchopleural fistula in the chemotherapy group with an incidence rate of 8. 70%, while there were 2 cases of bronchopleural fistula in the non-chemotherapy group with an incidence rate of 1. 85%. The difference between the two groups is statistically significant (P<0. 05). Conclusion Chemotherapy after pulmonary resection will increase the incidence rate of bron-chopleural fistula.

BACKGROUND: Evidence from in vitro study indicates that bone marrow stromal cells and undifferentiated mesenchymal cells can different into chondrocytes.OBJECTIVE: To observe the morphological changes of red bone marrow and periosteum allograft and its capability of chondrogenesis after transplantation in rabbits for repair of articular cartilage defects.DESIGN: Randomized controlled experiment with rabbits.SETTING: Department of Human AnatomY, Medical College of Yanbian University.MATERIALS: Fourteen Chinese rabbits of either sex with body mass of (2.15±0.30) kg.METHODS: This experiment was carried out in the Department of Human Anatomy, Medical College of Yanbian University between April 2001 and February 2002. Full thickness articular cartilage defect of 3.0 mm×6.0 mm was produced in the rabbits on the patellar surface of the femur in the 28knee joints, which were then randomized to receive either transplantation with autologous red bone marrow and periosteum graft into the bone defect (20 knees) or no grafts (8 knees). The morphological changes of graft were evaluated 7 days and 2, 4, 8, and 12 weeks after the operation by gross,optical microscopic, and electron microscopic observations with also assistance of image analysis.drocyte area of two groups.RESULTS: In the 12th week after the operation, the morphology, distribution and arrangement of the regenerated tissues were similar to normal cartilage in the knees with graft transplantation, and the regenerated tissues grew to be integrated with the surrounding normal cartilage with obscure boundary between them. But the boundary between the bone defect and surrounding normal cartilage was clearly observed in the ungrafted knees,and most of the defect was replaced by fibroblasts and collagen fibers with only some small chondrocytes seen in the superficial layer. Microscopic observation in the 4th week revealed the presence of chondrocytes in the superficial layer of the graft, and imaging analysis displayed greater single cell surface in the grafted than in the ungrafted knees in the 4th, 8th and 12th weeks [(248.70±16.62) vs (168.23 ±6.14) μm2, (267.79±28.88) vs (172.93±17.18) μm2, (175.75±13.24) vs (145.35±13.54) μm2, P ＜ 0.05].CONCLUSION: The chondrogenesis in autologous complex tissue graft of red bone marrow and periosteum occurs 8 weeks after the operation, and the morphology, distribution and arrangement of the newly generated cells are similar to that of the normal cartilage, with good mutual compatibility and complementarity in the regeneration activity between the two graft tissues.

Objective To study perioperative changes in serum levels of TNF-?, IL-6 and IL-10 in orthotopic liver transplantation without veno-venous bypass. Methods Sixteen patients with terminal liver disease underwent orthotopic liver transplantation under general anesthesia. Samples from arterial blood were obtained at beginning of surgery, before the anhepatic phase, 5min before recirculation, 15min and 60min after recirculation, 4h and 24h after operation, respectively. Serum levels of TNF-?, IL-6 and IL-10 were measured by ELISA. Results TNF-? and IL-6 concentrations were kept at a low level before operation, while IL-10 was not detected. The concentrations of IL-6 and IL-10 rose during the anhepatic phase (P

Objective:To study the clinical application of laparoscopic combined with multi-video debridement in treatment of complicated infectious pancreatic necrosis (CIPN).Methods:The clinical data of 34 patients with CIPN who were treated at the Department of General Surgery, Xuanwu Hospital, Capital Medical University from August 2017 to December 2019 were retrospectively studied. Based on the different video methods used, these patients were divided into 3 groups: the laparoscopic combined with intraoperative ultrasound group, the laparoscopic combined with choledochoscopy group and the laparoscopic group. The number of operations, operation time, blood loss, postoperative complication rates, mortality rates and total length of hospital stay were compared.Results:There were 13 patients in the laparoscopic combined with intraoperative ultrasound group, with age of (56.4±13.4) years. There were 7 patients in the laparoscopic combined with choledochoscopy group, with age of (48.0±8.4) years. There were 14 patients in the laparoscopic group with age of (51.4±15.6) years. The number of operations of the laparoscopic combined with intraoperative ultrasound group, the laparoscopic combined with choledochoscopy group and the laparoscopic group were (2.2±1.1), (1.6±0.8), (2.9±1.4), respectively. The number of operations of the laparoscopic combined with choledochoscopy group were significantly less than that of the laparoscopic group ( P<0.05), but there were no significant differences among the other groups ( P>0.05). The operation time of the laparoscopic combined with intraoperative ultrasound group, the laparoscopic combined with choledochoscopy group and the laparoscopic group were (70.5±22.9) min, (65.7±19.9) min, (51.5±15.4) min, respectively. The operation time of the laparoscopic combined with intraoperative ultrasound group was significantly longer than that of the laparoscopic group ( P<0.05), but there were no significant differences among the other groups ( P>0.05). There were no differences in blood loss, postoperative complication rate, mortality rates and total lengths of hospital stay among the three groups ( P>0.05). Conclusion:Laparoscopic combined with multi-video debridement after making full use of the advantages of each of the video methods, can be used to improve treatment outcomes of patients with CIPN.

OBJECTIVETo investigate the influence of parathyroid hormone and estrogen on alveolar bone metabolism of castrated female rats.

METHODSSixty-six female Wistar rats which were healthy and 4 months old were divided into two groups, with group SHAM (n = 18) and group ovariectomy (OVX) (n = 48). After 8 weeks of ovariectomy, the osteoporosis model was confirmed by examing 8 ovariectomized and sham-operated rats. The rest 10 rats in group SHAM were the control group (group A). The rest 40 rats in group OVX were divided into ovariectomized group (group B), ovariectomized and treated with estrogen (group C), ovariectomized and treated with parathyroid hormone (group D), ovariectomized and treated with estrogen and parathyroid hormone (group E) at random with 10 in each group. Group A and B injected physiological saline (1 mL x kg(-1)), group C injected estradiol benzoate (10 microg x kg(-1)), group D injected parathyroid hormone (20 microg x kg(-1)), group E injected parathyroid hormone (20 microg x kg(-1)) and estradiol benzoate (10 microg x kg(-1)). The intraperitoneal injection were maken every other day to rats in each group, which continued for 8 weeks. The bone mineral density (BMD), bone histomorphology and serum Ca, P, alkaline phosphatase (ALP) were measured after therapy.

RESULTSAfter 8 weeks of ovariectomy, the lumbar BMD of ovariectomized rats were significantly declined compared with those of the sham-operated rats (P < 0.05). Eight weeks later after the drug use, the BMD, %Tb.Ar, Tb.Th, Tb.N in group C, D, E were slightly elevated compared to group B, especially the group E (P < 0.05). Serum calcium and phosphorus values did not change significantly (P > 0.05). ALP values in group B was significantly higher than that in group A (P < 0.05).

CONCLUSIONIntermittent application of parathyroid hormone in small doses can increase alveolar BMD of castration rats and improve their bone structure. And it can have synergy effects on the treatment of osteoporosis if it is used combining with estrogen.
