Chinese Journal of Orthopaedics 1999;0(04):-
Objective To compare the diagnostic value of four signs for superior labrum anterior and posterior (SLAP) lesions of the shoulder. Methods The physical examination was performed randomly on 81 cases with abnormalities of the shoulder. There were four tests, including Kibler anterior sliding test, Liu crank test, O'Brien active compression test and Kim biceps load test Ⅱ. The arthroscopic examination were also performed. The result of the arthroscopic examination was considered as a golden standard, so that we could estimate the diagnosis value of the four tests according to the method of evaluation of diagnosis test on clinical epidemiology, their sensitivity, specificity, positive and negative predictive value, accuracy. Results There were 21 cases diagnosed as SLAP lesions by arthroscopy. The diagnosis value of Kim biceps load test Ⅱ was the highest among the four tests, in which 19 of true positive, 59 of true negative, 1 of false positive, only 2 of false negative case; while the sensitivity was 90.48%, specificity was 98.33%, positive predictive value was 95.00%, negative predictive value was 96.72%, and accuracy was 96.30%. However the sensitivity, specificity, positive predictive value, negative predictive value and accuracy of Kibler anterior sliding test were 76.19%, 96.67%, 88.89%, 92.06%, 91.33%; and those of Liu crank test were 85.71%, 93.33%, 81.82%, 94.92%, 91.35%; those of O'Brien active compression test were 80.95%, 91.66%, 77.27%, 93.22%, 88.89%. Conclusion Kim Biceps load test Ⅱ may be the best for clinical diagnosis of SLAP lesions of the shoulder.

Objective To study the susceptible drugs for Fusarium , and provide references for clinical treatment. Methods 40 F.solani and 6 F.moniliforme isolates were examined for the susceptibility to 7 antifungal drugs : AmB, ketoconazoie, miconazole, itraconazole, fluconazole , 5 Fc, and terbinafin by broth microdilution of M38 P recommended by NCCLS. Results 40 F.solani :MIC50 AmB 4 ?g/ml, ketoconazoie 16 ?g/ml, fluconazole 64 ?g/ml, itraconazole 16 ?g/ml, 5 Fc 64 ?g/ml, miconazole 16 ?g/ml, terbinafin 0.25 ?g/ml. MIC90: In addition to AmB and terbinafin , others antifungal agents were similar to MIC50, AmB 8 ?g/ml, terbinafin 4 ?g/ml. 6 F.moniliforme: except AmB and fluconazole were similar to MIC50 of 40 F.solani , others were lower than F.solani MIC50. Conclusion The MIC of terbinafin MIC is lower than that of others drugs, it could be used in the treatment of infections coused by Fusarium sp .

Objective To understand the efficiency of defluoridation facilities used in drinking water defluoridation in the rural high fluoride areas in Tianjin and the sanitary characteristics of treated drinking water. Methods The raw water samples and treated water samples were collected from 4 water stations where the electrodialysis technics was applied and 6 water stations where the reverse osmosis technics was applied and the facilities had been operated for 2-3 years in a county, as well as 3 water stations applied activated aluminium oxide adsorption technics and 2 water stations applied nanofiltration membrane technics in the other counties in Tianjin in 2002-2004. The pH value,turbidity, total dissolved solids, total hardness, fluoride, sulfate, aluminium, in all water samples were determined and evaluated according to the Sanitary Standard for Drinking Water(2001). Results The treated water samples from electrodialysis and reverse osmosis defluoridation facilities showed lower fluoride level(below 1.0 mg/L with fluoride removal rates of 90.01% and 75.32%),and lower total dissolved solids and total hardness levels with removal rates of 75.83%-93.48%. The treated water samples from nanofiltration membrane defluoridation facilities also showed lower fluoride level(below 1.0 mg/L with fluoride removal rates of 75.16%,and lower total dissolved solids and total hardness levels with removal rates of 64.90% and 77.22% respectively. Conclusion The investigated electrodialysis, reverse osmosis and nanofiltration membrane defluoridation facilities show a reliable efficiency and are suitable for application of removal of fluoride in drinking water with different levels of total dissolved solids in the rural high fluoride areas. The effects of defluoridated water produced by reverse osmosis defluoridation facilities on human health need to be studied further more.

Objective To study the application of percutaneous dilatational tracheostomy in the critical pa- tient. Methods Twenty eight critical patients performed percutaneous dilatational tracheostomy have been followed up in our hospital during 1996 - 2000, and the operating time, the perioperative complications and the following - up results were reviewed. Results all of the 28 patients were operated on successfully,no complication occurred dur- ing the operation , and little bleeding was observed, most of the patients have been followed up, the longest following - up period was 18 months, and the cosmetic effect was good. Conclusions The percutaneous dilatational tracheo- somy is a good less invasive surgical technique. It can meet the needs of the clinical tasks and worth to apply to some critical area.

Objective To study the effect of vasopressin (VS) on the small bowel circulation and the safety of emboliotherapy for the small intestinal hemorrhage by DSA. Methods Ten dogs were divided into three groups. Vasa recta were ligated 30min after VS infusion ended in group A( n =4), and 2h after VS infusion ended in group B( n =4), they were ligated without VS infusion in control group ( n =2). DSA were performed before and after VS infusion, before and after the ligation. The tested parts of intestine were resected to make the pathologic examination a week late. Results All branches of mesenteric arteries contracted and the contrast developed light in the intestinal wall after VS infusion. Branches contraction recovered but the contrast developed still slight in the intestinal wall about 30min after infusion ended. All manifestation of DSA recovered to normal 2h after infusion ended. In all groups, the blood vessel net can be seen but is fewer and scattered in the area of ligation. The collorate presented soon after the ligation. The pathologic examination proved that there was only mind mucosal ischemia in all groups. Conclusion The repressive effect of VS to the circulation of intestine weakened and then disappeared rapidly after the infusion ended. VS infusion had no significant effect on the safety of emboliotherapy for small intestinal bleeding when the infusion has been finished for more than 2hr. DSA can demonstrated the circulation state of the intestine before and after embolization.

Objective To assess the value of intraoperative ultrasonography during the uterus septum resection under a hysteroscope.MethodsThe uterus septum resection was performed under the guidance of transabdominal ultrasonography by using a hysteroscope in 30 patients.The operative procedure and the position of the hysteroscope were monitored,and the depth of the dissection and thickness of the myometrium in the fundus uteri were measured with transabdominal ultrasound during the operation.ResultsThe thickness between the incisal surface and serosal layer in the fundus uteri was within the normal limits in 28 cases.In 2 cases,the tissue was over-ectomized.The position of the urethral catheter balloon was correct in all of the 30 cases.Three months after the procedure,reexamination by transvaginal ultrasonography showed that the uterine cavity was normal in the patients.ConclusionsIntraoperative ultrasonography is quick,safe and precise for monitoring uterus septum resection.It is valuable for establishing surgical strategy and reducing operative complications.
