Objective To establish the blood glucose fluctuation diabetic rat model by subcutaneous injecting insulin. Method The male Sprague-Dawley (SD) rats were randomly assigned into two groups, normal group ( n =20) and model group ( n =40). Normal group rats were fed with normal diet, model group rats were fed with a high-sucrose-high-fat diet. After 6 weeks, a low dose of streptozotocin ( STZ ,30mg/kg) was injected to induce hyperglycemia in model group rats. And then the model group rats were ran-dom divided into two subgroups, diabetic group ( n = 20) and blood glucose fluctuation group ( n = 20). Blood glucose fluctuation group rats were induced by subcutaneous injecting insulin twice daily. All rats were executed after intervening for 3 months, metabolic cages were used to collect 24-hour urine one week before all rats were executed. Results The average blood glucose levels (MBG), the standard deviation of daily aver-age blood glucose (SDBG) and the largest amplitude of glycemic excursions (LAGE) were significant differ-ent (P<0. 05) among normal group, diabetic group and blood glucose fluctuation group. The 24 hours, pro-teinuria of diabetic group and blood glucose fluctuation group was higher than that in normal group[( 100. 38±7. 99)mg/24h vs (18. 13±1.41)mg/24h, (123. 71±11.23) mg/24h vs (18.13 ± 1.41 ) mg/24h, P <0.01] , and blood glucose fluctuation group was higher than diabetic group[(123. 71 ± 11.23 )mg/24h vs(100.38±7.99)mg/24h, P <0.05] . Conclusions The blood glucose fluctuation diabetic rats model was successfully induced by the method of subcutaneous insulin injection in diabetic rats twice daily.

With the advances in techniques of localization, numerous minimally invasive parathyroid surgery were developed including open minimal incision and endoscopic approaches. According to the research results and the experiences from Peking Union Medical College Hospital, the indication and preoperative preparation were discussed in this paper. Some suggestions were given for minimally invasive parathyroid surgery in China.

[Objective] To analyze the cases performed by unicompartmental knee arthroplasty in order to assess the early outcome,and to discuss the indications and the key points of surgical technique.[Methods]Under the principle of "slight undercorrection",15 patients were performed by unicompartmental knee arthoplasty with the technique of limited medial release if necessary.The HSS score,the fomeral tibial angle and the maxima degree of flexion and extension measured preoperatively and in the latest follow-up were analyzed by SPSS 13.0 with the method of paired t test.Meanwhile the angle of the posterior slope of the tibial implants was measured.[Results]Postoperatively the HSS score,the fomeral tibial angle and the maxima degree of flexion and extension were improved significantly in the latest follow-up,and the average angle of the posterior slope of the tibial implants was 4.2 degrees.[Conclusion]Unicompartmental knee arthroplasty has a satisfing early outcome.And it is very important to carry out the indications strictly.With the surgical technique of limited medial release,the flexional contracture could also be improved significantly.

Objective To investigate the relationship between sonic hedgehog(SHH)signaling pathway and chronic pancreatitis.Methods Thirty Wistar rats were randomly divided into the model group,experimental control group and blank control group,and there were 10 rats in each group.Trinitrobenzene sulfonic acid was infused into the pancreatic duct of the rats to induce pancreatitis in the model group.The pancreatic duct of the rats in the experimental control group were infused with 0.9％ sodium chloride solution.No treatment was performed on rats in the blank control group.The serum levels of bilirubin and amylase of the 3 groups were determined,and the histopathological alterations were studied.Expressions of patched-1(PTCH-1),smoothened (SMO)and SHH were detected by immunohistochemistry.All data were analyzed using the analysis of variance or Student's t test.Results The levels of total bilirubin(TBil)in the model group,experimental control group and blank control group from day 1 to day 35 were(3.17 ±0.21)μmol/L-(9.28 ±2.15)μmol/L,(3.44 ±0.54)μmol/L-(3.76 ± 0.15)μmol/L,(2.45 ± 0.32)μmol/L-(3.27 ± 1.43)μmol/L,respectively.The levels of amylase in the model group,experimental control group and blank control group were(1124 ± 143)U/L-(1522 ± 169)U/L,(1123 ± 104)U/L-(1007 ± 141)U/L,(1014 ± 115)U/L-(1013 ± 142)U/L,respectively.Compared with the experimental group and the blank control group,the serum levels of TBil and amylase in the model group were increased significantly from day 7 to day 35(F =14.81,16.27,18.13,11.49,17.91;11.54,10.24,12.64,21.11,15.38,P ＜ 0.05),and fibrotic proliferation of pancreatic tissues were found at day 35;the expressions of PTCH-1,SMO and SHH in the pancreatic tissue was increased significantly in the model group.Conclusion SHH signaling pathway is activated in the tissue of pancreatitis in rats,it might play an important role in the genesis of pancreatitis.

Thyrotropin releasing hormone (TRH) and naloxone were compared in their antagonism to the effects of analgesia,addicton-induction,movement restatraining,respiration depression,LD50:etc of morphine.It was found that TRH was entirely different from naloxone in that it was not antagonistic at all to the morphine effects mentioned above.So TRH would be a better choice than naloxone in the treatment of traumatic shock.

This paper studied the protective effect of gypenosides (GPS) on oxidative damage of myocardium of guinea pig, Using xan-thine-xanthine oxidase (X-XOD) producing free radicals. In the isolated guinea pig papillary muscles, X- XOD produced the quick positive inotropism at first and then the continuous negative one, shortened the functional refractory period (FRP) and elevated the excitability and increased the automaticity induced by adrenaline, inhibited the activity of superoxide dismutase (SOD) and increased the content of malondi-aldehyde (MDA). GPS inhibited the negative inotropism of papillary muscles produced by X-XOD,resisted the changes of FRP, automaticity and excitability induced by X- XOD. Meanwhile, GPS antagonized the effect of X-XOD which decreased activity of SOD and increased the content of MDA. These studies indicate that GPS can protect the myocardium from oxidative damage.

Objective: : To investigate whether development of the sph e noid sinus affect the surgical approach via saddle area. Methods: The pneumatization of sphenoid sinus of 50 cadaver heads was studied through t hinner CT scanning of coronal, sagittal and axial position. The sphenoid sinus w as classified according to the degree of pneumatization of sphenoid sinus toward s sphenoid bone, small wing of sphenoid bone and epippium. Results: There were 4% conchal, 18% pre-sellar, 18% semi-sellar, 14% sellar, 46% sellar -occipital in 100 sphenoid sinus cases. The transversal diameter of left and ri ght was 18.48 mm and 17.58 mm; The sagittal diameter of left and right was 2 2.20 mm and 20.82 mm, The vertical diameter of left and right was 21.02 mm and 2 0.38 mm. The distance between centre track and the later wall of sphenoid sinus was 14.78 mm in left side and 15.18 mm in right side. Conclusion: Thinner CT scanning with coronal and sagittal position can clearly show pneum atization of sphenoid sinus on both sides. Different pneumatization of sphenoid sinus provide anatomical basis for choosing operation approach.
