Objective To discuss the causes,treatment and prophylaxis of surgical jaundice after laparoscopic cholecystectomy (LC). Methods A retrospective analysis was carried out in 16 cases of surgical jaundice consisting of 14 cases from this hospital out of 3 092 cases of LC from January 1994 to January 2002 and 2 cases transferred from other hospitals. Results Out of the 16 cases,residual bile duct stones were found in 9 cases,and bile duct injuries had taken place in 7 cases (2 cases of cystic duct stump leakage,3 cases of common bile/hepatic duct injuries and 2 cases of recurrent jaundice resulted from aberrant bile duct leakage).All the 16 cases were cured by surgery and no bile duct stricture occurred after surgical procedures. Conclusions Strict following indications of LC and normative surgical performance are the keys to the decrease of surgical jaundice after LC.The patient should be given active surgical intervention once surgical jaundice occurs.

AIM: To established an HPLC/MS/MS method for the study of pharmcokinetics of PMEA-Na (the mono-sodium salts of 9-[2-(phosphonomethoxy) ethyl] adenine) in beagle dogs. METHODS: PMEA-Na and internal standard 9-(3-phosphony-methoxypropyl) adenine were isolated from plasma by protein precipitation with methanol, and then analyzed adopting multiple reaction monitoring (MRM) mode. Using Xterra MS column, the mobile phases consisted of methanol:water:formic acid (25:75:0.5) at a flow rate of 0.25 ml·min-1. Beagle dogs received the intravenous dosage of PMEA-Na at 1.0, 3.0 and 6.0 mg·kg-1. Pharmacokinetic parameters were obtained from concentration-time curves by non-linear least-squares regression using the program DAS. RESULTS: The linear calibration curve was obtained in the concentration range of 0.02 to 20 mg·L-1 (r=0.999), and the limit of quantitition was 20 μg·L-1. The within-day and internal-day precisions (RSD) were less than 6.5% and 10.8%, respectively. The accuracy was 97.1%～107.3%. After a single dose studies in dogs the AUC were 2.3±0.5, 8.2±1.3 and 18.5±1.3 mg·L-1·h; the t1/2 were 3.9±1.8, 8.4±1.5 and 8.9±0.6 h; the CL were 0.44±0.09, 0.35±0.05 and 0.31±0.03 ml·h-1·kg-1 at the dose level of 1.0, 3.0 and 6.0 mg·kg-1 respectively. CONCLUSION: The analytical method is sensitive and specific for investigation the pharmacokintics of PMEA-Na in beagle dogs.

Objective To research the infection of Rotavirus in children in Hangzhou area and to get the message of the feature of epidemiology. Methods Stool specimens of 156 children with suspected acute viral enteritis in Hangzhou between September 2006 and January 2008 were collected. Rotavirus were detected for all specimens by enzyme linked immunosorbent assay(ELISA). Results Rotavirus was detected in 86 of 156(55. 1% ) specimens;all the 86 strains belonged to group A. The highest frequency of group A RV detected was 57% (70/123) in patients aged 6 ～ 24 months. Conclusion The major pathogen of acute viral enteritis in children in Hangzhou area between September 2006 and January 2008 was RV. Children under the age of 2 years seemed to be more susceptible to RV infection than those of other age groups. The symptoms of RV enteritis were more severe than those of other viral enteritis.

In the marketing theory, service disparity model is a simple effective tool, capable of figuring out the five clusters of reasons leading to service failure. This article applies it in the community health service domain. Through the efforts of healing the five gaps in service delivery, including Consumer expectation-management perception gap, Management perception-service quality specification, Service quality specifications-service delivery gap Consumer expectation-management perception gap and Service delivery-external communications gap, we hope to improve the community health service quality radically.

Research on disease-syndrome combination is the main approach and method of research on integrative traditional Chinese and Western medicine. Disease-syndrome combination embodies the complementary advantages of traditional Chinese medicine and Western medicine. It discusses the relationship between diseases and syndromes through an interdisciplinary approach, and explores rules of disease diagnosis and treatment based on differential diagnosis. Thanks to the development of modern life science techniques, research on disease-syndrome combination has made great achievements. This article mainly introduced the application and the development prospects of new techniques, such as data mining, system biology, epigenetics, biological network and network pharmacology in the research on disease-syndrome combination in recent years, with a purpose to provide the ideas and the methods for further research and clinical application.

Objective To observe the changes in hypersplenism after orthotopic liver transplantation(OLT) and investigate the effect of OLT on hypersplenism. Methods Based on the clinical data of 14 eligible OLT patients operated on in our hospital during two and a half years, an analysis of the pre operative values of the thickness of the spleen, blood WBC and PLT count was made,and the postoperative pattern of changes of portal flow velocity was observed. Results Blood WBC and PLT count returned to normal 1 month after the operation, and the thickness of spleen reduced about 17.0% in the first month , but had no additional change at 1 year later. Portal flow velocity increased significantly 1 month after operation , then decreased slowly in the first year. Portal flow velocity , blood WBC and PLT count were all significantly related to the thickness of the spleen. Conclusions The high velocity of portal flow after OLT was mostly attributed to increased flow from the splenic vein; the main cause of the decrease in the level of blood WBC and PLT in hypersplenism before operation is augmentation of splenic volume; the recuperation of hypersplenism after OLT relies on the extent of reversion of splenic volume. It is not necessary to perform splenectomy in patients with hypersplenism when they receive OLT.

Objective To evaluate the effects of different selection criteria on the prognosis of hepatocellular carcinoma(HCC)patients undergoing liver transplantation(LT)and to evaluate a new criterion.Methods A retrospective analysis was performed on 81 consecutive patients with HCC who underwent LT.The survival rates of the patients who met different criteria such as Milan.UCSF(University of California San Francisco UCSF).and Pittsburgh(Pitt)modified TNM criteria were calculated by KaplanMeier method,and the value of different criteria was evaluated.The Long-Rank test and COX proportional hazards regression model were performed to analyze the prognostic factors.the model of criteria was established according the most important prognostic factors.Using the Kaplan-Meier method,the suitable cut-offs of every variable ifl the model were found by comparing the survival and the number of the patients who met the cut-off,and considering the significant difference between the patients who met and exceed the cut-off at the same time.Resuits The 1,2,3-year accumulative survival rates of the 19 patients who met Milan criteria were 87.7%,87.7%,and 52.6%respectively:the 1,2,3-year disease free survival rates of them were 88.9%,72.7%,and 72.7%respectively.The 1,2.3-year accumulative survival rates of the 26 patients who met UCSF criteria were 87.2%,80.5%,and 55.2%respectively;the 1,2,3-year disease free survival rates of them were 84.1%,68.4%,and 68.4%respectively.With our new expanded criterion as of solitary tumor≤8 cm in diameter.or no more than 3 tumors,with the largest≤6 am,and a total tumor diameter≤10 cm.there was no significant difierence in 1,2,3-year sunrival rates and disease free survival rates(89.0%,81.8%,71.8%,and 81.9%,72.4%,72.4%.)as compared with Milan or UCSF criteria.but with this new criterion more patients(a=41)would be eligible for transplantation with a comparable long term survival.and the difference of the accumulative survival rates and disease free survival rates of the patients who met and exceed the new criteria was significant(P＜0.05).Conclusion The new indication is acceptable because the criteria does not adversely impact survival.

ObjectiveTo introduce the new method of full reconstruction for Ⅰ to Ⅲ-degree finger defect.MethodsFor reconstruction of Ⅰ to Ⅱ-degree finger defect, the surgery procedure was as follows:Harvest part of nail,skin and dorsal part of distal phalanx from hallux to form a composite flap,and then the flap was transplanted to the finger stump to reconstruct the defect part of the finger.The design of the composite flap was according to the recipient part. For reconstruction of Ⅲ-degree finger defect, the skin included in the flap could be designed according to the recipient part, but the bone can only be harvested from the fibulodoral part of the hallux and far from the insertion of the extensor hallucis longus tendon, which means the length was limited.If the bone length was not enough,one bone mass with appropriate size and shape was harvested from the iliac bone and connected with the bone of the composite flap. Some cases of Ⅲ-degree finger defect were reconstructed by harvesting interphalangeal joints from the second toes to reconstruct distal interphalangeal joints(DIP). The bone defect was reconstituted by bone mass from the iliac bone to conserve the contour of the second toe.The hallux wound was covered by a local flap or free flap transplantation.ResultsOne hundred and eighteen cases (126 fingers) of Ⅰ-degree defect, one hundred and eighty-seven cases (201 fingers) of Ⅱ-degree defect and 90 cases (111 fingers) of Ⅲ-degree finger defect were applied full reconstruction. All the reconstructed fingers survived completely and the configurations were similar to real fingers. Followed up our work on 150 fingers from a number of patients, between 1 and 11 years after the original surgery.Total ranges of motion of the reconstructed fingers got to over 180°.The reconstructed DIP joints had the range of motion of 15°-40°. The donor halluxes and toes were conserved with the normal length,relatively primary appearance and full function. ConclusionFull reconstruction for Ⅰ to Ⅲ-degree finger defect has great advantages in that the reconstructed finger has very realistic configuration as well as ideal function and the donor hallux is conserve well.
