Objective To explore the interventional methods to treat recurrent jaundice after palliative bilio intestinal anastomosis in patients with malignant obstructive jaundice due to cholangiocarcinoma. Methods Ten patients with recurrent jaundice after bilio intestinal anastomoasis were retrospectively evaluated. Nine of ten underwent PTCD with metallic stent placement, one underwent the inner outer draining catheter procedure. The patients were evalualed with comparison in regard to preoperative conditions, TBIL,ALT,GTP and AKP values.Results Stent placement was successful only once in all 10 cases with successful rate of 100%. TBIL,ALT,GTP and AKP values were significantly lower 7 days postoperative by than that preoperation. Subsidence of jaundice was satisfactory for 100% in all patients after the treatment. Conclusions Percutaneous placement of biliary metallic stents is a safety, simple, low complication method for managing recurrent jaundice after palliative bilio intestinal anastomosis for the terminal stage of malignant obstructive jaundice.

Objective To investigate the diagnostic value and feasibility of PTC diagnosis on pancreaticobiliary maljunction (IBM), and to summarize the PTC radiological characteristics of PBM. Methods Clinical findings and cholangiopancreatographic results were analyzed retrospectively for a group of consecutive 363 patients with obstructive jaundice receiving the PTCD therapy. Meanwhile the standard selected for cases and diagnostic conditions were established. The length and diameter of pancreaticobiliary common duct, the diameter of pancreatic duct and common bile duct and the confluence angle were measured respectively. The t test and rank sum test were used to analyze the result statistically. Results Thirty-eight cases were radiologicaUy diagnosed as PBM owing to the reference standard and the detection rate was 10.5% (38/363). The length of common duct was (12.6±7.9)mm. The significant difference existed between it and normal value (6ram) (t=5.15 , P <0.05). The site of duodenal papilla had influence on the length of common duct. The diameter of common bile duct, pancreatic duct and common duct near the confluence are (3.7±1.9 ) mm, (2.4±1.3) mm, (3.3±1.4 ) mm, respectively. There was no statistical difference between them and the normal value (t=1.79,2.85,5.72, P>0.05). Fifteen patients' duodenal papilla located the middle of descending duodenum. The length of common duct was (10.6±9.1)mm , the confluence angle was 51.1°±28.0°, the number of the duodenal papilla locating in the inferior 1/3 of descending duodenum, juncture , horizontal part of duodenum was 10, 8,5, respectively. The length of common duet were (9.9±3.7), ( 18.6±8.9), ( 13.9±3.5 ) mm, respectively. The confluence angle were 54.0°±18.6°、48.7°±12.6°、74.4°±18.5°, respectively . The site of duodenal papilla had significant influence on the length of common duct(X2=14.51, P <0.05). Conclusion PTC is a safe, feasible, method to diagnose PBM, and it demonstrates the characteristic findings of PBM.

Clinical data and radiological findings of 78 patients with distal radial fractures,who underwent plain X-ray film and muhislice CT (MSCT) examinations,were retrospectively analyzed.Twenty nine associated carpal bone factures were detected on X-ray film in 21 cases;while 47 associated carpal bone fractures were detected on MSCT in 29 cases (P ＜ 0.05).The missed diagnosis rate of X-ray was 38％.Results indicate that MSCT can significantly improve the detect rate,which should be recommended for diagnosis of associated carpal bone fractures in distal radial fractures.

Objective To investigate the survival principle of SARS-conarovirus (SARS-Cov) in environments and to explore the inactivation effect of chlorine and chlorine dioxide on SARS-Cov with the aim of providing some basis for blocking its'main route of transmission. Methods SARS-Cov were added into the excrement samples, urine samples and other water samples and were disinfected by sodium chlorite and chlorine dioxide. The survival ability of SARS-Cov and the effects of those two disinfectants on the inactivation of SARS-Cov were observed. Results The survival of SARS-Cov changed with the variation of temperature in external environment.It was showed that SARS-Cov could only survive for 2 days in hospital sewage, domestic sewage and dechlorinated tap water, while 3 days in excrement samples, 14 days in physiological saline and 17 days in urine samples protected from light in vitro at 20 ℃ . At 4 ℃, SARS-Cov could survive for 14 days in all above water samples and 17 days in excrement samples and urine samples. Resistibility of SARS-Cov to disinfectants in sewage sample was lower than those of E. coli and f2 phage. At the same disinfectant dosage or residual chlorine concentration , chlorine had better inactivation effect than chlorine dioxide did.The residual chlorine concentration of more than 0.5 mg/L or chlorine dioxide concentration of more than 2.19 mg/L was enough for the complete inactivation of SARS-Cov in sewage, but not enough for E. coli and f2 phage. Conclusion The survival time of SARS-Cov was shorter and more susceptible to chlorine and chlorine dioxide in external environment.

Objective To investigate the feasibility of reverse transcription_polymerase chain reaction (RT_PCR) to evaluate the inactivation efficacy of viruses in water, and to discuss the mechanisms of HAV inactivation by chlorine. Methods Cell cultrue, ELISA method and long_overlapping RT_PCR were developed to detect the infectivity, antigenicity and entire genome of HAV inactivated by chlorine. Results The cell culture results revealed that the infectivity was completely inactivated after exposure to 10 mg/L or 20 mg/L of cholrine for more than 30 minutes, the antigenicity was completely inactivated after exposure to 10 mg/L of chlorine for 60 minutes. The 5' nontranslated region (5'NTR) of neculear acids of HAV was the most sensitive to chlorine, which was confirmed with the inactivation of infectivity of HAV. Conclusions The results implied that the inactivation of HAV by chlorine was due to the loss the 5' NTR. It was believed that PCR could be used to assess the efficacy of disinfection of HAV by chlorine and also could be applied to research the inactivation mechanisms of viruses by disinfectants.

Objective To observe the clinical efficacy of thread embedding plus Chinese medication in treating primary dysmenorrhea due to blood stagnation caused by cold accumulation. Methods Totally 136 patients with primary dysmenorrhea due to blood stagnation caused by cold accumulation were randomized into a treatment group and a control group, 68 in each group. The treatment group was intervened by thread embedding at Shiqizhui (EX-B 8) and bilateral Ciliao (BL 32) plus Chinese medication;while the control group was by Chinese medication alone. The dysmenorrhea symptom score and Visual Analogue Scale (VAS) were observed before and after intervention, and the clinical efficacies were compared. Results The total effective rate and recovery-markedly effective rate were respectively 93.8%and 78.1%in the treatment group, versus 85.2%and 50.0%in the control group, and there was a significant difference in comparing the recovery-markedly effective rate (P<0.05). After intervention, the dysmenorrhea symptom score and VAS score were significantly changed in both groups (P<0.01);there were significant differences in comparing the symptom score and VAS score between the two groups (P<0.05). The half-a-year follow-up study showed that the total effective rate and recovery-markedly effective rate were respectively 90.6%and 68.8%in the treatment group, versus 70.6%and 38.2% in the control group, and the differences were statistically significant (P<0.05, P<0.01). Conclusions Thread embedding plus Chinese medication is an effective approach in treating dysmenorrhea due to blood stagnation caused by cold accumulation, and it’s easy-to-operate and causes less pain.
