Objective To investigate the effects of serum leptin and tumor necrosis factor-?(TNF-?) on nutrition states in patients with chronic obstructive pulmonary disease (COPD). Methods The serum leptin and TNF-? levels were examined. Body mass index (BMI) and percent age of normal body weight(NW%) were measured. The correlation between leptin and other parameters was analysed. Results Serum leptin and TNF-? levels in acute exacerbation of COPD were significantly higher than those in the stable patients with COPD and control (P

This study aimed to investigate the synergistic effect of lidamycin (LDM) and rituximab on human B cell lymphoma Ramos cells. Cell proliferation was measured using MTS assay, cell apoptosis was analyzed by Annexin V-FITC/PI assay, the expression of apoptosis related proteins was analyzed by Western blotting, and the in vivo lymphoma inhibition was verified using BALB/c mice inoculated via tail vein using Ramos cells which stably expressed pEGFP-N1 plasmid. The results showed that, after the pretreatment with rituximab for 48 h, rituximab and LDM showed significantly synergistic effects on cell proliferation. Cells in combined treatment group had a higher apoptosis rate than that in LDM treatment group. Compared with the LDM treatment group, the expression of apoptosis-related proteins such as Cleaved caspase-3, Cleaved caspase-7, Cleaved caspase-9 and Cleaved PARP in combined treatment groups increased, and expression of cIAP-2 and Bcl-2 decreased. The result of in vivo experiment showed that, in the combined treatment group, the survival time of BALB/c mice was significantly longer than the mice in control group and LDM treatment group, and the degree of tumor accumulation and metastasis to lymph nodes and spleen was lower.

Purpose　The aim is to modify the pyrogenic pathol ogy mo del induced by injection of saccharomycetet water in rats,and to eliminate the t emperature decline period after injection of saccharomycete water sc.Metho ds　It was measured that the anus temperature of both two groups of rats (one group was injected of incubated saccharomycete water and the other inj ected unincubated saccharomycete water sc) 1,2,3,4,6,8 h after injection respect ively.Results　The anus temperature had no decline period and the temperature rose quickly in the group of injected with incubated saccharomyc ete water (in 34℃thermostasis water).There was significant difference(P＜0.05 or P＜0.01)between incubated group and unincubated group in temperature risin g by t-test.Conclusion　No temperature declining peri od was observed in the pyrogenic pathology model of rat, if those rats were trea ted with saccharomycete water which was incubated at 34℃for 0.5 h.

ObjectiveTo study the role of laparoscopic splenectomy (LS) using the anterior approach with sequential layered dissection. MethodsFrom December 2007 to July 2009, we performed 27 LS using the anterior approach with sequential layered dissection. The clinical data were retrospectively analyzed. ResultsThe range of splenic length was 8-20 cm. Accessory spleen was found in 6 patients (22.2%). The mean operative time was 125 mins. The mean intraoperative blood loss was 90 ml, and the mean postoperative stay was 5.5 days. ConclusionsLaparoscopic splenectomy using the anterior approach with sequential layered dissection could be carried out smoothly and rapidly. It reduced accidental injuries and shortened the operative time.

Objective To observe the influence of tumor necrosis factor-alpha(TNFα) on skeletal muscle protein catabolism in rats with chronic obstructive pulmonary disease (COPD) and the effects of indomethacin (IND) on it. Methods Duplicated COPD model rats were divided into two groups: the malnutrition group and the normal nutrition group. The malnutrition group were further divided by randomized block design into four groups. Isotonic physiologic saline was administered to group A, the control and the normal nutrition group, and different doses of oral IND were administered to groups B, C, and D weight, concentrations of TNFα, contents of 3-methyl-histidine ( 3- M H ) and tyrosine (Tyr) in the diaphragm and extensor digitorum longus muscle homogenates were measured before and after the intervention. Results Before the intervention, the concentrations of TNFα in the serum of malnutrition groups were all significantly higher than those of normal nutrition group and the control group. After the intervention: (1) The concentrations of TNFα in the serum of the rats of group B, C and D were significantly lower than the group A, especially in group C. The levels of TNFα in serum and body weight of model group rats were negatively correlated ( r = -0. 846, P ＜0. 01 ), as well as the diaphragm and extensor digitorum longus muscle weights ( r = - 0. 778, P ＜ 0. 01; r = - 0. 772, P ＜ 0. 01 ). (2) The levels of 3-methyl-histidine in the diaphragm and extensor digitorum longus muscles of the intervention group C was lower than the COPD normal nutrition group, as well as the intervention groups B and D. The contents of tyrosine in the diaphragm and extensor digitorum longus muscles of the intervention group C was lower than that of the COPD normal nutrition group,as well as the groups B and D. The body weight growth value of the intervention group B were slightly higher than the group A, without significant difference( P ＞ 0. 05 ), while the group C was significantly higher than the group A ( P ＜ 0. 01 ). Conclusions TNFα is involved in the occurrence of COPD malnutrition and skeletal muscle amyotrophy. IND can reduce the TNFα levels in the serum and the catabolic rates of the skeletal muscle proteins in malnutrition rats with COPD, so as to improve partly the skeletal muscle atrophy.

BACKGROUND: Traditional treatment includes conservative therapy and surgical treatment on bronchial pleural fistula. With the development of endoscopic therapy, a new safe and effective method is concerned. OBJECTIVE: To summarize the therapeutic effect of treating bronchopleural fistula using bronchoscopy-guided injection of fibrin sealant combined with gelatin sponge filled and microwave following after lung resection. METHODS: Totally 8 cases of bronchial fistula patients were received injection of fibrin sealant after microwave and gelatin sponge filled by bronchoscopy, including 6 males and 2 females, mean aged 53.8 years (39-73 year-old). Cases 1 and 2 received left upper pulmonary Iobectomy, cases 3 received left lower pulmonary Iobectorny, case 4 received right lower pulmonary Iobectomy, cases 5 and 6 received right upper pulmonary Iobectomy, and the cases 7 and 8 received pneumonectomy. bronchopleuralfistula occurred after postoperative Chemotherapy in cases 4 and 8. RESULTS AND CONCLUSION: The case 8 was failed to treatment due to the large orificium fistulae (> 5 mm) and disappointed results after 6 times plugging. The other 7 patients were cured successfully. The injection time was correlated to the size of orificium fistulae, and the plugging was successful for 4 patients with less than 3 mm orificium fistulae. However, a third or fifth plugging was performed for 3 cases with 3-5 rnm orificium fistulae. No surgery-related complications occurred in all patients. Bronchoscopy guided injection of fibrin sealant combined with gelatin sponge and microwave is a safe and effective method for bronchial fistula.

BACKGROUND: Bushen Huoxue Tongluo Capsule, a well-known traditional prescription, exhibits remarkable treatment outcomes in knee osteoarthritis, but the underlying mechanism is not fully understood. OBJECTIVE: To explore the regulatory effect of Bushen Huoxue Tongluo Capsule on miR-27a of synovial cells in Sprague-Dawley rats with knee osteoarthritis. METHODS: The model of knee osteoarthritis was established in 120 Sprague-Dawley rats using Hulth method, and then these rat models were randomized into four groups, followed by given75 mg/kg normal saline (blank control group), 34 (low-dose group), 75 (medium-dose group) and 140 (high-dose group) mg/kg Bushen Huoxue Tongluo Capsule aqueous solvent via gavage according to body mass, respectively, twice daily, for consecutive 2 courses (15 days as a course) with 2 days in between. The synovium and cartilages were removed after each course, and the expression of miR-27a in the knee joint synovium and chondrocytes was determined by real-time quantitative PCR. RESULTS AND CONCLUSION: Gross observation found that the degeneration of synovium and cartilage in the Bushen Huoxue Tongluo Capsule groups was milder than that in the blank control group. Real-time PCR revealed that there was an increasing trend in the expression of miRNA-27a in the synovium and cartilage in each group, especially in the high-dose group, and there was a significant difference between groups (P < 0.05). Our findings show that Bushen Huoxue Tongluo Capsule can suppress the reduced expression of miRNA-27a in the synovium and chondrocytes in rats with knee osteoarthritis, further alleviating knee degeneration and protecting the knee from damage.
