Total Glucosides of Paeony Root ( TGPs, 5-40 mg/kg) had a dose-related increasing effect on the survival time of mice under normobaric hypoxia. TGPs (20 mg/kg) had a significant increasing effect on survival time of mice under hypobaric hypoxia & a decreasing effect in the oxygen consumption in mice. TGPs ( 40mg/kg ) decreased the mortality of mice from the acute hypoxia induced by KCN. Increasing effect on the survival time of mice under normobaric hypoxia of TGPs was significantly antagonised by chlortrimeton. The efficacy of TGPs (icv 2.5-5 mg/kg) approximated to that of TGPs (ip 5-40 mg/kg) respectively. It suggested that the effect of TGPs on resistance to hypoxia was produced by central nervous system. The efficacy of TGPs ( icv) was significantly antagonised by chlortrimeton. It was shown that the effect of TGPs was produced by H1-receptor. In the experiment of resistance to hypoxia of TGPs (ip or icv), we measured the change of rectal temperature of mice. The data indicated the positive corr- elation of both effects of TGPs (r=0.58, P

Objective To investigate the clinical value of non-invasive atherosclerosis detection technology for the early diagnosis of young type 2 diabetic patients with lower extremity vascular disease .Methods 78 young patients with type 2 diabetes( T2DM group) and 80 cases in the healthy control group were detected some indicators , including upstroke time(UT)%,mean artery pressure(%MAP),the pulse wave speed(baPWV) and ankle-brachial index(ABI) by Omron arteriosclerosis detector.Those items were comprehensively used to evaluate the diabetes patients of lower extremity vascular disease .Results There were statistically significant differences in UT ,%MAP, baPWV and ABI between the T2DM group and the control group(t=4.218,8.798,-3.392,5.136,all P<0.01). ABI of 6 patients was less than 0.9.Moreover,five of these 6 patients examined by color Doppler ultrasound had arte-rial plaque formation.As to patients of ABI >0.9,2 cases of them were promoted lower extremity arterial stenosis and occlusion,and then they were certified by color Doppler ultrasound .Conclusion Non-invasive atherosclerosis detec-tion technology has better accuracy to the diagnosis of young type 2 diabetes patients with atherosclerosis ,and may find patients with blocked arteries earlier ,provide better value for early clinical intervention .

Objective To investigate the effect of Xiexin Decoction(XXD) on the early diabetic nephropathy(DN) of diabetic rats induced by high-fat diet with injection of streptozotocin(STZ).MethodsMale Sprague-Dawley rats were divided into two groups and fed with normal pellet diet(NPD) or high-fat diet(HFD),respectively,for a period of four weeks and then HFD-fed rats were ip injected with STZ.The diabetic rats were divided into three groups: model group,XXD group,and metformin group.After 13-weeks ig administration,fasting blood glucose(FBG),glycated hemoglobin(HbAlc),blood lipids(TG and TC),serum insulin(INS),renal function,kidney index,albumin in urine,and the renal histology and ultrastructure were observed.Results Compared with the model group,XXD reduced the levels of water intake,food consumption,urine volume,HbAlc,insulin resistance index(IRI),creatinine clearance rate(CCr),albumin in urine and blood lipids(P

AIM: To observe the curative efficacy of Shenkang Bolt(SKB) in treating chronic renal failure(CRF) with blood silt and damp pathogen syndrome. METHODS: The randomized,parallel and controlled trial were used.38 cases in treatment group were treated with SKB,and 40 cases in control group were clystered with Chinese herbal medicine.The changes of the cumulative scores of traditional Chinese medicine(TCM) syndrome,the levels of serum creatinine(SCr) and creatinine clearance rate(CCr) before and after treatment in both groups were observed. RESULTS: The total effective rate was 81.5% in the treatment group,but 75% in the control group.The scores of TCM syndrome and the levels of SCr were both significantly decreased(P(0.05)). CONCLUSION: SKB can markedly improve the clinical manifestations of CRF with blood silt and damp pathogen syndrome,decrease the levels of SCr,but increase CCr.There was no difference between Chinese herbal clysis and Shenkang Bolt in curative effect,but it is convenent to take Shenkang Bolt.

Objective To evaluate the efficacy and safety of bilateral transversus abdominis plane block (TAPB)combined with bilateral rectus sheath block (RSB)in abdominal surgery. Methods Ninety ASA Ⅰ or Ⅱ patients,35 males,55 females,aged 19-79 years,with body mass index 18-30 kg/m2 ,scheduled for elective laparoscopic cholecystectomy were randomly divided into three groups(n=30):ultrasound-guided bilateral TAPB combined with bilateral RSB group (group TR),ultrasound-guided bilateral TAPB group (group T),patient-controlled intravenous analgesia (PCIA)group (group P).In group TR,ultrasound-guided bilateral TAPB were performed with 20 ml of 0.22% ropivacaine mesylate injection in each side and ultrasound-guided bilateral RSB were per-formed with 10 ml of 0.22% ropivacaine mesylate injection in each side before surgery.In group T, ultrasound-guided bilateral TAPB were performed with 20 ml of 0.22% ropivacaine mesylate injection in each side and ultrasound-guided bilateral RSB were performed with 10 ml of NS in each side before surgery.In group P,ultrasound-guided bilateral TAPB were performed with 20 ml of NS in each side and ultrasound-guided bilateral RSB were performed with 10 ml of NS in each side before surgery, and PCIA was applied in group P.BP,HR,SpO2 were observed when patients were sent into the op-erating room, 2 minutes before trocar puncture, and 2 minutes after trocar puncture, the consumption of propofol and remifentanil used during the surgery were recorded.The score of visual analogue scale (VAS)during rest and movement were recorded at 2,6,12,24 h after surgery.The patient analgesia satisfaction and the adverse reactions were recorded.Results Compared with group T and group P,group TR had less change of BP before and after trocar puncture(P <0.05).The VAS score was significantly lower in group TR after operation(P <0.05).There were no statistical significant differences of VAS score at 24 h after operation among the three groups.The patient anal-gesia satisfaction was significantly better in group TR than other two groups (P < 0.05 ). Conclusion Ultrasound-guided bilateral transversus abdominis plane block combined with bilateral rectus sheath block is of safety and much efficacy of postoperative analgesia in patients undergoing laparoscopic cholecystectomy.

Objective To investigate the effects of icarrin on the activity and protein expression of core binding factor otl(Cbfa1) in rat osteoblasts cultured in vitro,and to explore whether mitogen-activated protein kinase (MAPK) pathway is involved in this process.Methods Calvarial osteoblasts were obtained from newborn (<24 h) SD rats by trypsin-coUagenase digestion method.The second generation osteoblasts were cultured in the medium containing icariin (10 ng/ml) or estradiol (10-8 mol/L) with or without extracellular-signal regulated kinase (ERK) inhibitor (UO126) or p38MAPK inhibitor (SB203580).Nuclear protein was extracted from osteoblasts.And then the activity of Cbfa1 was detected by ELISA.The amounts of Cbfa1 protein were detected by Western blot.Results Calvarial osteoblasts were obtained successfully and were used in this study after indentified by alkaline phosphatase and mineralized nodus staining.Cbfa1 expression and the activity in osteoblasts were up-regulated by both icariin and estradiol (P<0.05).The effects were partly inhibited by addition of U0126or SB203580 (P<0.05).Conclusions Either icarrin or estradiol can stimulate the proliferation and maturation of cultured osteoblasts in vitro via up-regulating the activity and expression of Cbfal.The MAPK signal pathway inhibitor seems to partly decrease Cbfa1 activity.It suggests that MAPK pathway may be involved in the transduction of icariin's impact on proliferation and mineralization of osteoblasts.

Objective To evaluate the clinical characteristics and surgical risks for elderly patients with gastric cancer. Methods The clinical data from 607 patients, who received surgical therapy for gastric cancer between January 2006 and December 2009, were retrospectively analyzed.Among them, 267 patients were over 65 years of age, and the other 340 patients (≤65 years of age)were served as control. Complete surgical resection was done by doctors in same group. The preoperative complications such as cardiopulmonary disease and post-operative complications as well as pathologic patterns were compared between two groups. Results Coexisted diseases were found more in elderly patients than in controls (68.91% vs 31.63 %, P＜0.01). Whereas there was no significant difference between two groups with respect to post-operative complication [28. 19% (75/267)vs 25.59 % (87/340)]. However, the incidence of cardiopulmonary complications, especially pulmonary infection, was higher in elderly patients than in controls (17.23% vs 5.29% ,P＜0.01). The digestive tract complications were related to the pattern of radical operation. Post-operative complication occurred less in patients treated with D1 radical operation than those with D2 and D3 radical operation.Conclusions The incidence of post-operative complication in elderly patients with gastric cancer was closely related to the surgical method. The elderly patients may has less complications if they were operated with D1 radical method which can reduce risk of complication and improve the quality of life.

Objective To study the safety and efficacy of fast track program in anorectal surgery perioperative period. Methods One hundred and sixty-nine cases of rectal cancer were divided into the study group of 86 patients with fast track program, and the control group of 83 patients with traditional programs by random digits table. Both groups were compared from the time out of bed, the first intestinal discharge time,intravenous fluids stopping time,length of hospital stay,total cost of treatment and the incidence of postoperative complications. Results The study group compared with the control group: the first intestinal discharge time [(33.6 ± 12.9) h vs. (81.7 ± 20.1) h], intravenous fluids stopping time [(4.5 ±1.3) d vs.(7.4 ± 1.6) d],and length of hospital stay [(5.6 ± 1.2) d vs.(8.9 ±2.7) d],the total cost of treatment [(15 000 ± 3000) yuan vs. (16 000 ± 4000) yuan], the differences were statistically significant (P ＜ 0.01 or ＜ 0.05),and had less incidence of postoperative complications in study group than that in control group [5.8% (5/86) vs. 16.9% (14/83)], the difference was statistically significant (P ＜ 0.05).Conclusions Fast track program in anorectal surgery perioperative period is safe and effective, beneficial,conducive to rehabilitation of patients.

Objective To explore the microneurosurgical technique and prevention of postoper-ative complications for the fourth ventricle tumors in adults. Methods We retrospectively analyzed the clinical data of 68 patients with the fourth ventricle tumors between August 2005 and August 2007 in Xiangya Hospital after microsurgical operation. Tumors were excised by inferior vermis cere-bellar approach or cerebellomedullary fissure approach. The extent of tumor removal should take into consideration the possible injury of brain stem respiratory center, especially tumors adherent to the brain stem. Cerebral aqueduct obstructions were removed in all patients, suspending dura on the neck muscles during closing skull to eliminate scalp hydrops. Results There were 58 total tumor excisions and 10 subtotal tumor excisions. No patient died and no suboccipital hydrops took place before dis-charge in this study. Postoperative symptomatic hydrocephalus was found in 10 patients, but it was cured by ventricle-abdomen shunt. Hemorrhage in tumor lumen happened in 4 patients, who received second microsurgery. Drugs were given to 8 patients with intracranial pneumatocele, 10 with intracra-nial infection, and 18 with upper gastrointestinal hemorrhage. Five patients out of the 16 tracheoto-mies recovered well by mechanical ventilation. Conclusion Protecting the life center of brain stem and dredging the aqueduct outlet completely were the key to surgical success. Therapeutic effect could be improved by adept microneurosurgical techniques after operation. The prognosis of patients may be improved by preventing complications actively and combined therapy after the operation.
