For observation on clinical therapeutic effect of modified Wei Er Fang on gastric precanceraus lesion (GPL), 90 cases of GPL were divided into 3 groups, the treatment group treated with modified Wei Er Fang, the control group I treated with Wei Fu Chuan and the control group I with Bismuth subcitrate, 30 cases each group. Results indicated that the total effective rate for clinical symptoms was 96. 67% in the treatment group which was significant different from 60. 00% in the control group I (P 0. 05), but the therapeutic effect on heterotypic proliferation in the treatment group was superior to those in the two control groups. It is showed that modified Wei Er Fang has a better action of reversing gastric precancerous lesion.

Objective To investigate clinical results of bilateral triceps bradhii approach in Gartland Ⅲ supracondylar fracture of humerus in children by comparing with reduction interne and plaster immobilization. Methods 102 children with Gartland Ⅲ supracondylar fracture of humerus,4 ～ 13 years old,from May 2003 to May 2009,were randomly divided into operation group and control group,51 cases separately. The operation group was treated by bilateral triceps bradhii approach, while control group was treated by reduction interne and plaster immobilization. All patients were made function exercise 4 weeks later,X-ray check periodically and followed up about 16 months with angle patronner and elbow joint function recorded. According to Flynn clinical function criteria,all patients were classified and analyzed. Results After follow-up and elbow joint function evaluation,48 cases ( 94. 1% ) show excellent and good results,3 cases(5.9% ) fair and poor in operation group,32 cases(62. 7% ) and 19 cases(37. 3% ) in control group. The differences between two groups was statistically singnificant ( P < 0. 05). Conclusion Comparing with reduction interne and plaster immobilization, bilateral triceps bradhii approach in Gartland Ⅲ supracondylar fracture of humerus in children has good clinical results and may be more effective therapy.

Objective To investigate the effect of dexmedetomidine and small dose of ketamine on the hyperalgesia and brain-derived neurotrophic factor (BDNF) mRNA in the spinal cord of rats with neuropathic pain.Methods Forty-five male Sprague-Dawley rats,weighing 240-270 g,were randomly divided into 5 groups (n =9 each):sham operation group (group S),spinal nerve injury (SNI) group,ketamine group (group K),dexmedetomidine group (group D) and dexmedetomidine + ketamine group (group K+ D).The animals were anesthetized with intraperitoneal 10% chloral hydrate 400 mg/kg.SNI was produced by exposing the sciatic nerve and its branches and ligation and transection of tibial nerve and common fibular nerve in groups SNI,K,D and K + D.In S group,the sciatic nerves and its branches were only exposed but not ligated.In groups D,K and K + D,dexmedetomidine 40 μg/kg (2 ml),ketamine 10 mg/kg (2 ml) and mixture of dexmedetomidine 20μg/kg + ketamine 5 mg/kg (2 ml) were injected intraperitoneally,respectively,once a day for 21 consecutive days starting from 24 h after successful SNI surgery.While the equal volume of normal saline 2 ml was injected instead in S and SNI groups.The paw withdrawal threshold to mechanical stimuli (PWT) was measured at 1 day before surgery,and 3,7,14 and 21 days after surgery.Three rats were sacrificed after measurement of pain threshold at 1 day before surgery,and 7 and 21 days after surgery and the lumbar segments (L4-6) of the spinal cord were removed for determination of BDNF mRNA expression in spinal dorsal horn by real time PCR.Results Compared with group S,the PWT was significantly decreased,and the expression of BDNF mRNA in spinal dorsal horn was up-regulated after surgery in groups SNI,K,D and K + D (P ＜ 0.05).The PWT was significantly higher,and the expression of BDNF mRNA in spinal dorsal horn was lower after surgery in groups K,D and K + D than in group SNI,and in group K + D than in groups K and D (P ＜ 0.05).Conclusion The combination of dexmedetomidine and small dose of ketamine produces a synergistic antinociception in rats with neuropathic pain,and direct or indirect inhibition of BDNF mRNA expression in spinal dorsal horn is involved in the underlying mechanism.

Objective To investigate the protective effect of exercise on osteopenia female rats caused by ovariectomy and its mechanism. Methods Twenty-four female rats aged 6 months were randomly divided into 3 groups: control group(CON),ovariectomized model group(OVX) and exercise group(Ex).The ovariectomy operation was performed with rats in OVX and Ex groups. Rats in Ex group were trained on a treadmill at a velocity of 18m/min for 1h, once daily for 5 days a week. Each group of rats were sacrificed at 12 weeks postoperatively and Dual-energy X-ray absorptiometry was carried out to measure the bone mineral density(BMD) of the femur. IGF-1 proteins in trabecular bone of proximal femur were examined by using immunochemical stain and the intensity of IGF-1 was determined by use of imaging analysis techniques. The apoptotic osteocytes in the trabecular bone of proximal femur were detected by using terminal-deoxynucleotidyl mediated nick end labeling (TUNEL) technique. Results The BMD of CON, Ex and OVX group was (0.170?0.011)g/cm2,(0.154?0.013)g/cm2 and(0.167?0.013)g/cm2, respectively. The difference of the BMD level between Ex and CON groups was not significant, however, the BMD level in OVX group was significantly lower than that of the Ex and CON groups (P

Objective To assess the protective effect of mastoparan-1(MP-1) on acute lung injury in mouse model with endotoxemia(ETM) induced by lipopolysaccharide(LPS),and to investigate the possible mechanism of protcetive effect.Methods The endotoxemia murine model was reproduced by tail vein injection of LPS(5mg/kg) in mice.Animals were randomly divided into normal control group(n=8),endotoxemia group(n=48) and MP-1-treatment group(MP-1 was injected in 3mg/kg at the same time of LPS injection,n=48).Animals of the latter two groups were sacrificed at 2,6,12,24,48 and 72 hours after injection,and then the blood and lung tissue samples were collected.Plasma LPS was assayed using kinetic turbidimetric limulus test,TNF-? and IL-6 were measured by appropriate ELISA kits,TLR4,TNF-? and IL-6 mRNA expressions in lung tissues were analyzed by real-time RT-PCR,myeloperoxidase(MPO) activity of lung tissues was determined by spectrophotometric method,and the pathological changes in lung tissues were observed under microscope.Result The plasma levels of LPS,TNF-? and IL-6 in the mice of endotoxemia group were increased at 2-48 hours after LPS injection(P
