Objective: Study the relationship between the activity and structural parameters of aminoquinolines. Methods: A new type of topological indices, called the hydrogen - association classified molecular electrongativity - distance vector ( H - MEDV) developed in our laboratory, has been used to describe the chemical structure of 40 aminoquinolines. Reasonable molecular modeling results were achieved by a multiple linear regression ( MLR). Results; For two sets of aminoquinolines, the correlation coefficient ( R) between the estimated and the observed activities were 0.920 and 0.910 respectively. Conclusion; Hie results suggest the estimation stability and predictive ability of the model based on the H - MEDV descriptors.

Objective To evaluate the value of MRI used in the shoulder pain. Methods 34 cases with complaint of shoulder pain underwent MR scanning, the findings of both MRI and surgery were analyzed comparatively.Results MRI of shoulder in 34 cases showed full-thickness and partial-thickness tears of the rotator cuff, tendinitis, glenoid labrum tear, synovitis, biceps tendinitis, biceps dislocation and tumors. In 13 patients received arthroscopy or operation. MR findings of 11 cases were correlated to surgical result, one case diagnosed as tendonitis by MRI was showed partial-thickness tears of the rotator cuff during operating, one case in which the MRI showed normal was found biceps tendonitis by arthroscopy. Conclusion MRI can show complex anatomy of shoulder and has high accuracy in diagnosis of shoulder pain, it is a value method for shoulder pain.

Objective To observe the effect of ammonia silver nitrate on early caries.Methods 100 cases of children with early caries treated in our hospital from April 2015 to December 2016 were admitted to conduct research and analysis.The children were divided into the control group and the observation group by double blind,and random method 50 cases in each group.The control group was treated with caries removal,the observation group was treated with carious worn out joint ammonia silver nitrate.After treatment, the two groups of children suffering from dental pulp tissue TNF-a, IL-8 concentration, the recurrence rate, filling rate falling, the rate of suffering from pulpitis, pain conditions were analyzed.Results After treatment, the observation group with TNF-α, IL-8 concentrations were lower than the control group(t=21.961,t=23.836), the difference was statistically significant (P<0.05);The recurrence rate, suffering from pulpitis rate was significantly lower than the control group, and the difference was statistically significant (P<0.05);the observation group after treatment in children with severe pain and painless was significantly lower than the control group, and the difference was statistically significant (P<0.05).Conclusion Ammonia silver nitrate is an effective and safe treatment for early caries, which can relieve the pain and discomfort in children, it is a safe and effective method of treatment and should be promoted and used in the clinic practice.

Objective To raise the vigilance for pregnancy complicated with acute abdominal diseases and to reduce the maternal mortality rate. Methods A retrospective study was done. Results (1) The maternal mortality of pregnancy complicated with acute abdominal diseases was 1 31/10 5 in the period of 1989～1993, which was significantly higher than that in the period of 1994～1998 (0 71/10 5). (2) The main cause of maternal deaths was misdiagnosis and the rate of misdiagnosis was 72 7%.(3) Among the acute abdominal diseases, pregnancy complicated with pancreatitis ranked the first that accounted for 54 6%. Conclusions For the purpose of reducing the mortality rate of pregnancy complicated with acute abdominal diseases, the correct diagnosis and proper treatment especially for those with acute pancreatitis are important.

Objective Pathologically, sometimes it is rather difficult to make differential diagnosis among hepatocellular, cholangiocellular and mixed type of hepatic tumors. The aim of this study was to analyze the immunohistochemical features of mixed type of hepatocarcinoma and to propose some useful diagnostic criteria. Methods Fifteen cases of the hepatic tumor were examined by routine histological and immunohistochemical methods with S P technique. Results The mixed type of hepatic tumor accounted for 3.39% of all cases of primary hepatocarcinoma in the same period. Histologically, all the mixed type of hepatic tumors revealed some characteristics of hepatocellular and cholangiocellular carcinomas, one of them was collision tumor. Immunohistochemically, 10 cases of the tumor were positive for ? fetal protein(AFP) in the hepatocellular carcinoma area, while all 15 tumors were negative for AFP in all cholangiocellular carcinoma areas. Cytokeratin(CK8) was positive in the hepatocellular carcinoma areas of all mixed tumor, whereas positive in cholangiocellular carcinoma areas of 13 cases; CK19 was positive in cholangiocellular carcinoma areas of all the tumors, while positive in hepatocellular carcinoma areas of 13 cases. Bcl 2 gene product was positive in 66.7% of this tumor, in which it was mainly expressed in cholangiocellular tumor area and in hepatocellular areas of five cases. AB/PAS stain for mucin was positive in cholangiocellular tumor regions of all the tumors. Conclusions Diagnosis of mixed hepatocarcinoma should be made mainly based on combined analysis of the data from pathological features, immunohistochemical phenotypes and histochemical stain for mucinous material.

Objective To compare the content variation of catalpol between single and mixed decocting Rehmanniae Radix and Paeoniae Radix alba; To preliminarily explore the variation rules of compatibility of Rehmanniae Radix and Paeoniae Radix alba. Methods HPLC method was used with Waters Symmetry C18 column (4.6 mm×150 mm, 5 μm), flow rate of 1.0 mL/min, detection wavelength of 210 nm, column temperature at 25 ℃. The mobile phase was acetonitrile-0.01% phosphoric acid in water isocratic elution system. Results Catalpol regression equation was Y=270 054X-57 724, r=0.999 6, showing good linear range among 0.225–7.2 μg. The average recovery rate was 101.15%, RSD=0.39%. The average content of catalpol in the mixed decoction of Rehmanniae Radix and Paeoniae Radix alba was 18.66%more than the single decoction of Rehmanniae Radix. Conclusion The content of catalpol in mixed decoction is higher than the single decoction of Rehmanniae Radix and Paeoniae Radix alba. The mixed decoction is favorable for the dissolving of catalpol from the medicine. The compatibility of Rehmanniae Radix and Paeoniae Radix alba is rational.

Objective To evaluate the diagnosis and treatment of left renal vein entrapment syndrome. Methods The clinical data of 10 cases of left renal vein entrapment syndrome were retrospectively analyzed.Their mean age was 24 years (range,14-37 years).Of them 7 cases presented with non-glomerular origin hematuria;2,with orthostatic proteinuria;1 with hematuria accompanied by proteinuria.Color Doppler sonography showed that the dilated segment of the left vein was three-fold than the strictured segment in diameter,and magnetic resonance angiography (MRA) showed that the left renal vein was compressed in 9 cases. Results Stent placement across the left renal vein was performed in 7 cases.Superior mesenteric arteriectomy and replantation were performed in 3 cases.The operations were all successful.Follow-up of 1-5 years showed that the clinical symptoms were improved and urine tests were normal. Conclusions Non-glomerular hematuria or orthostatic proteinuria is frequently found in left renal vein entrapment syndrome.Left renal vein entrapment syndrome can be diagnosed by Doppler sonography,MRA and cystoscopy in the presence of hematuria or proteinuria.Generally,conservative treatment and careful follow-up are conducted in these patients.Surgical and radiologic interventional procedures are effective alternatives for those with glomerular dysfunction and complications.
