[Objective]To investigate the clinical results and significance and mechanism of early dislocation rate after total hip arthroplasty following the posterolateral approach with posterior capsulotendinous repaired.[Method]The incidence of early dislocation and the prosthetic range of rotation motion among 212 consecutive primary THAs with the posterior capsule and the short external rotators which had been sutured to the medius tendon was reviewed retrospectively,and was compared to the results of 486 consecutive unilateral primary THAs with a complete posterior capsulectomy.[Result]During a 6 months to 5 years(3.7 years in average)following-up,there were significant differences between two groups.In patients with posterior capsulotendinous repair,two of 224 primary total hip arthroplasty(0.9%) had an early posterior dislocation.In patients with a complete posterior capsulectomy,27 of 486 primary total hip arthroplasty(5.6%) had an early dislocation.The difference was statistically significant(x~2=8.51,P

A series of 286 cases with gastric cancer identified by endoscopy and surgery was subjected to the study to probe the correlation of endoscopic findings in morphology,size and cell differentiation with cancerous in- vasion and metastasis of the tumor by means of TNM staging.Results showed that the superficial size of the lesion 3cm increased in T_2,up to 44.9% in T_4;lymphatic involvement was found in 12.5% of T_1a;remote metastasis occurred in 4.7% of T_2,being statistically higher(P

The aim was to establish an effective screening microarray at genus level for Pospiviroid. We analyzed nucleotide sequences from Pospiviroid viroid and designed 19 probes with genus identification characteristics. The standards of these probes included the characters of (i) a GC content between 40 and 60%, (ii) less than 50% of single nucleotide, (iii) less than 4 continuous mononucleotides, and (iv) less than 6 nucleotides in the inner hairpin. We synthesized microarrays by using these probes on glass slides. The validation results of microarray probes show effective signals from chrysanthemum stunt viroid and tomato planta macho viroid standard samples hybridization. The sensitivity results show that the microarray detected 200 pg/microL of total RNA. The microarray can be used to screen Pospiviroid viroid.

Objective To evaluate the charateristics of biliary stricture after orthotopic liver transplantation(OLT) by ultrasound. Methods Diametes,thickness,characteristic echo of bile were observed by ultrasound in 41 patients with biliary stricture after OLT,and the results were compared with those of 46 patients without biliary complication after OLT.Results The diameter of intrahepatic bile,thickness of bile,incidence of intrahepatic bile dilation or hyperechogenicity in biliary stricture patiens were higher than those in patients without biliary complication,there were significant differences between two groups(P＜0.05).Conclusions The series of ultrasonographic character such as bile dilation,thickeness or hyperechogenicity of biliary wall,thin of bile duct are available to diagnose biliary stricture.

Objective To study a new operative method for treatment of hepatic venous occlasion without (associated) pathologic change of inferior vena cava or long-segment stricture. Methods A total of 44 cases of Budd-chiari syndrome with hepatic venous occlusion without pathologic change or long-segment stricture of (inferior) vena cava underwent combined mesocaval C-shunt, ligation of splenic artery, and esophagogastric (devascularization).Results Pre-shunt portal venous pressure was 36cmH2O(31~45 cmH2O, 1cmH2O=0.0098kPa) and post-shunt pressure fell to 26 cmH2O(21~33 cmH2O),the mean reduction was 10 cmH2O. One patient died of liver failure. A slight degree of hepatic encephalopathy occurred in 2patients who recovered after conservative treatment.Chylorrhea occurred in 4 patients, and it spontaneously disappeared 7d to 3.5months after operation. 39 patients(88.6% follow up) were followed up for 6months to 7years , and there was no case of recurrent bleeding nor hepatic encephalopathy. Ascites disappeared in 31cases,and was markedly reduced in 7 cases .The prosthetic grafts were patent as shown by color Doppler ultra sound in all followed-up patients.Conclusions This operation is simple and effective for B-CS with hepatic venous (occlusion) but not associated with inferior vena caval pathologic change or long-segment stricture.

OBJECTIVE:To study the preparation of compound levofloxacin eye drops and its quality control,then observe its clinical effect.METHODS:Levofloxacin was used as basic remedy mixed with dexamethasone sodium phosphate and phos?phate was adoped as buffer,while EDTA-2Na as stabilizer.Finally the content of levofloxacin was determined by UV-spec?trophotometric method.RESULTS:The preparations was stable and within the range of2～6?g/ml,the concentration of lev?ofloxacin had a linear relationship with absorbance(C=26.1780A—1.0838,r=0.9997).The average rate of recovery was100.34%and RSD was0.44%(n=5).CONCLUSION:This preparation has a good effect with simple preparing technique and reliable quality control.

OBJECTIVE:To establish the preparation technic and method of qualit y control of fleroxacin-tinidazole(FLX-TNZ)hollow effervescent suppository METH ODS:36-type semi-synthetic aliphatic ester was used as base material and doub le-wavelength UV-spectrophotometry was adopted for determination of the conten ts of fleroxacin and tinidazole RESULTS:The average recovery rates(n=5)of fler oxacin and tinidazole were 99 72% and 99 08%,while RSDs were 0 95% and 1 02% respectively CONCLUSION:This method has a sound design and feasible tec hnnology

Objective To investigate the association between the RoSCo scoring system and the postopera tive complications of laparoscopic partial nephrectomy.Methods The clinical data of 127 patients with laparoscopic partial nephrectomy in our hospital from 2010 to 2015 were retrospectively analyzed.By studying all patients' preoperative clinical data,we give all the patients the RoSCo score,then divided all the patients into the RoSCo low group (3-4),RoSCo moderate group (5-6),RoSCo high group (7-8).Respectively study the association between the RoSCo score and Clavein score,operative time,intraoperative blood loss,warm ischemia time and length of hospital stay after laparoscopic partial nephrectomy.Results The RoSCo score was associated with postoperative complications of laparoscopic partial nephrectomy (P ＜ 0.05) and was more accurate than the RENAL score alone.There were significant differences in bleeding,warm ischemia time,hospital stay and operation time between the low,middle and high groups of RoSCo (P ＜ 0.05).Conclusion The RoSCo scoring system can be used to assess the complications of laparoscopic partial nephrectomy.

Objective To study the repeatability and consistency of normal female pelvic floor structure using transperineal real‐time three‐dimensional ultrasound .Methods Forty‐two cases of normal adult female were evaluated by two different experience operator ,using the real‐time three‐dimensional ultrasound diagnostic apparatus .The bladder neck movement degrees and the levator hiatus area were observed after Valsalva condition .Differences between the groups were compared .Intraclass correlation coefficient (ICC) ,the coefficient of variation (CV) and Bland‐Altman analysis of consistency were evaluated . Results The bladder neck movement degrees and the levator hiatus area measured by the experienced operator (operator 1) and less experienced operator(operator 2) were (18 4.8 ± 5 8.4)cm and (17 7.9 ± 5 4.8) cm ,(17 5.3 ± 3 9.5)cm2 and (17 3.1 ± 4 3.2)cm2 ,respectively .There was no significant difference between the two operators ( P > 0 0.5) .The intra‐ICC were 0 8.9 and 0 9.0 ,CV were 7 2.6% and 3 0.3% .Experienced operator repeatability (ICC= 0 9.9 ,0 9.4) was slightly higher than the less experienced researchers (ICC 0 9.2 ,0 8.1) .The analysis results of Bland‐Altman image showed good consistency between two different operators .Conclusions The current study proves real‐time three‐dimensional ultrasound is a reproducible method for female pelvic floor structure assessment ,and the reproducibility is very well .The detection performance of experienced operator slightly better than the one with less experience ,strengthen the training of junior doctors may further improve the accuracy of measurement .
