Atropine, as an anticholinergic agent, can inhibit the synthesis of acetylcholine in the arcuate nucleus in hypothala-mus and then reduce the secretion of GH. The present study showed that GH secretion was increased during exercise and the elevated GH level could be inhibited by atropine in normal subjects, while in patients with active acromegaly the high basal GH levels could be inhibited neither by 100g of glucose loading nor by 0.6 mg atropine. The blood sugar concentrations remained unchanged during atropine test. It was suggested that atropine test could be used as a GH release inhibitory test in acromegalic patients with overt diabetes mellitus.

Objective To investigate the efficacy of emergency endoscopy for the treatment of patients with acute obstructive suppurative cholangitis(AOSC)and the difference compared with therapy of routine operation.Methods After ERCP were performed on 36 patients with AOSC,EST and/or ENBD were executed subsequently.To those asthenic patients complicated with diseases or tumors,ENBD was used to alleviate symptoms and then decided whether to take stones secondly or drain by ERBD.Biochemical indicators,physical sysmtoms and signs were monitored so as to compare with those of 32 patients with AOSC treated by routine operation.Results The clinical effect was satisfactory,and the relief of pain,incidence of complicated diseases,hospital stay,level of serum TBIL after treatment had significant difference between those in study group and in control group(all P＜0.05).Conclusion Endoscopic therapy is safe,easy and minimally invasive,which is suitable for the patients with AOSC.

Objective: To evaluate the compatibility of the nHA/PA composite implant. Methods: The component was implanted into the proximal humeral metaphysis of rabbits. The prosthetic humeral head replacement was performed in 20 rabbits. The rabbits were killed at the 3rd, 6th, 12th, 24th week after operation. Specimens were observed by histology and immunohistochemitry. Results; Immuno-histochemistry results showed that there were some CD4+ , CD8+ lymphocytes infiltrated into the interface at the 3rd week, without other inflammatory cells being observed. While at 6th, 12th, 24th week, neither lymphocytes nor inflammatory cells were seen. Conclusion; The nHA/PA prostheses show good biocompatibility.

Objective To observe the effects of hyperbaric oxygen on metabolic syndrome risk factors in the elderly. Methods Sixty-one patients were randomly divided into a hyperbaric oxygen (HBO) group which inhaled pure oxygen at 0.2 MPa,a normal pressure oxygen (NPO) group which inhaled oxygen at 0.1 MPa, and a normal pressure air (NPA) group which inhaled air in 0.1 MPa. Metabolic syndrome risk factors were then assessed before and after treatment. Results Before treatment, the incidence of metabolic syndrome risk factors did not differ between the various groups. After treatment, blood sugar, blood pressure,blood fluidity and insulin resis-tance had declined significantly in the hyperbaric oxygen group, and the difference as compared to the NPO and NPA groups was significant. Conclusion The results indicate that HBO can help control metabolic syndrome risk factors in the elderly, controlling blood sugar, adjusting blood pressure, reducing blood viscosity, and improving dyslipidemia.

Objective:To compare the clinical effect of lateral and posterior approaches during the total hip replacement(THA) with Minimal-Incision Surgery(MIS).Methods:Twenty-three cases were performed with lateral approach,All were performed by the same surgeon.23 cases who had undergone a MIS THA with lateral approach were compared with 36 cases who had undergone MIS THA with the posterior approaches.The average follow-up period was 12 weeks.The patients were compared with respect to the length of the incision,surgical time,intra-operative blood loss,Harris hip score,component malpositioning,complications.Results:There were no differences between the two approaches with regard to the length of the skin incision,operating time,Harris hip score,component malpositioning and major complications.Statistically significant differences were found in two groups in terms of blood sedimentation and C-reaction protein.Conclusion:Both approaches can be effectively performed without increased risk of complications.Significant benefits of posterior approaches include less soft tissue damage.

Objective:To compare the clinical effect of high tibial osteotomy (HTO) with Giebel blade plate or straddle nail internal fixation for the treatment of osteoarthritis of knee with varum.Methods:Twenty-three cases of knee OA with genu varum were performed with HTO,in which 8 case by using Giebel blade plate and 15 cases by using straddle nail.Results:All patients were followed up.The genu varum defection were corrected obviously.Six months after operation,comparison between the two groups showed no significant differences in scoring on HSS standard.One case of nail rupture and two cases of loss of anticipant angle occurred in the group of straddle nail.Conclusion:HTO with either Giebel blade plate or straddle nail both apparently shows many advantages in the treatment of osteoarthritis of knee.HTO with Giebel blade plate can exercise more early and have much less complications than HTO with straddle nail internal fixation.

Objectives:To elucidate the changes on contents and molecular structures of chondroitin sulfate in aneurysmal wall of aortic dissection and disscuss its likely roles in the pathogenesis and progression of aortic dissection.Methods:After glycosaminoglycans in aortae being abstracted,chondroitin sulfate were separated and purified respectively through DEAE Sephacel by ion exchange chromatography and then identified by cellulose acetate electrophoresis.Chondroitin sulfate were hydrolyzed with chondroitinase ABC,and then its disaccharide compositions were analyzed by high performance capillary electrophoresis.Results:Compared with the control group, chondroitin sulfate increased significantly(P

Objective To study the effect of operation after neoadjuvant chemotherapy on gastric cancer patients with Ⅲ,Ⅳ grade.Methods 120 gastric cancer patients with Ⅲ,Ⅳ grade were selected.52 cases in the control group were given routine operation,68 cases in the observation group received neoadjuvant chemotherapy plus operation treatment.The operation resection rate,solid tumor progress assessment and postoperative recurrence rate in three months,six months and one year were observed.Results The radical resection of the observation group was 62.24％ (43/68),which was significantly higher than that of the control group 46.15％ (24/52) (x2 =5.81,P ＜0.05).The palliative resection and laparotomy of observation group were 20.59％ (14/68) and 16.18％ (11/68),which were significantly lower than those of the control group (x2 =4.04,4.92,all P ＜ 0.05).Tumor remission of the observation group was 61.76％ (43/68),which was significantly higher than that of the control group 50％ (26/52)(P ＜ 0.05).The tumor progress of the observation group was 17.65％ (12/68),which was significantly lower than that of the control group 28.85％ (15/52) (x2 =4.17,P ＜ 0.05).The tumor recurrence rates in 3 months and 6 months of the observation group were 10.29％ (7/68) and 17.65％ (12/68),which were significantly lower than those of the control group (x2 =4.61,P ＜ 0.05).Conclusion Neoadjuvant chemotherapy before operation can improve the operation resection rate,reduce the relapse rate,delay the recurrence and metastasis of gastric cancer,improve the prognosis of the patients.
