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.

To investigate the classification and modeling of traditional Chinese medicine (TCM) syndromes in post-hepatitic cirrhosis by partial least-squares (PLS) method, and to study the clinical application of PLS method in TCM research.

Objective To assess the outcome of liver transplantation in patients over sixty years of age,in order to attempt to expand the indications of liver transplantation. Methods From August,2000 to January,2002, the clinical data of 36 patients who underwent liver transplantation in our department were analysed retrospectively. Of the 36 cases, the data (operating time, the length of hospitalization, rejection rate and ICU stay days after operation) of 5 patients whose age were ≥60 years (elderly group) and the data of 31 patients whose age were under 60 years (

Objective To study how to decrease the hospital cost of liver transplants. Methods Fifty-four(patients) who underwent liver transplantation at our hospital within 2 years were analyzed retrospectively. The hospital costs of the patients with different liver function before operation, the costs of the(ICU-dependent), as well as the costs of the non-survival group with the survival group were analyzed and compared. Results The average hospital cost of all the patients was about 340 000 yuan. The cost of(pharmacy), anesthesia,(disposable)(materials), transfusion and laboratory tests accounted for 86.9 percent. The(average) cost of Child grade C(patients) was about 410 000 yuan, was 130 000 yuan higher than that of grade A or B patients. The cost of the ICU-dependent was 240 000 yuan greater than that of the(ICU-independent). The(non-survival) group incurred an average cost of 130 000 yuan higher than the(survival) group. Conclusions For decreasing the hospital cost of liver transplants significantly,it is best to encouraging the patients to receive(liver)(transplants) under good conditions.

Objective To summarize the initial experience in application of mesohepatectomy for the treatment of central liver tumors while focusing on its indication, short-term and long-term prognosis and especially outlining its technical details. Methods The clinical data of 3 patients receiving mesohepatectomy from December 2007 to March 2009 in our hospital were retrospectively analyzed.The imaging characteristics were summarized to convey the indication details. The technique details of the operation were outlined so as to reduce blood loss or other complications during and after the operation. The post-operative course and follow-up data were also collected and analyzed. Results Two patients suffered from primary hepatocellular carcinoma with liver cirrhosis and the other from giant hemangioma. The tumors were located in Couinaud yegment Ⅳ and/or Ⅷ. The average blood loss and operative duration were 800 ml and 7 h, respectively. Blood liver function tests returned to normal within 7 days postoperatively and the patients were discharged after that. No complications occurred. The follow-up for 7-15 months showed that there was no recurrence. Conclusion Mesohepatectomy is the principal choice of treatment for centrally located liver tumors. For the safety and avoidance of complications, the doctor should abide by the concept of segment-oriented hepatectomy and apply the updated techniques such as CUSA (Cavitron ultrasonic surgical aspirator). For patients with compromised liver function, mesohepatectomy might be superior to extended bepatectomy. Thus, the application of mesohepatectomy should be expanded. Meanwhile, further investigation is needed for its full evaluation.

Objective To summarize the experience in the diagnosis and treatment of elastofibroma dorsi,focusing on the clinical features,the specific radiological characteristics,and the typical pathological alterations.Methods Clinical data of 10 cases of pathologically confirmed elastofibroma dorsi from January 1997 to April 2008 were retrospectively reviewed.Results Most patients were female(8/10)in this series.All the lesions were located within the muscles in the subscapular region.There were 13 lesions in 10 cases(3 cases with bilateral involvement).Seven patients complained of pain and feeling of foreign body,and three were asymptomatic.The size of the masses was between 4 centimeters to 12 centimeters,averaging at(7.46 ±2.70)centimeters.Except for the early 3 cases,accurate diagnosis was made in all the other 7 cases before the histological exams solely based on the physical examination and imaging findings.Marginal excision was done for all the cases under general anesthesia.Fluid accumulation,as the only kind of complication was found in 3 cases which was resolved by repeated paracentesis.No recurrence was found during the follow-up period(4 months to 125 months,median 11 months).Conclusion Elastofibroma dorsi is a rare,pseudotumoral lesion usually found in elderly women.It is a very special type of soft tissue tumors that its diagnosis can usually be made solely on the basis of unique imaging characteristics and physical examination before the histological exam.Surgical marginal excision is the choice of treatment with good short-term and long-term results.
