Objective To approach the treatment value of endoscopic sphincterotomy for the dysfunction of Oddi sphincter in postcholecystectomy syndrome.Methods Endoscopic sphincterotomy was undergone in 28 cases with ultimate diagnosis of Oddi sphincter dysfunction after BUS, ERCP , basal sphincter pressure examination and ruled out the patients with retained or recurrent stones,stricture or carcinoma in the bile duct having postcholecystectomy syndrome.Results Symptoms disappeared completely after the treatment in 18 cases,alleviated apparently in 5 cases and other 2 cases after the second treatment,without alleviation in 3 cases,the effective rate is 89.3%(25/28).No severe complication happened.Conclusion It is assumed that endoscopic sphincterotomy is a micro-traumatic,safe and effective treatment for the dysfuction of Oddi sphincter in postcholecystectomy syndrome.

Objective To research the clinical safety and feasibility of self-made devices in gasless laparoscopic surgery. Methods A total of 5 generations of gasless laparoscopic devices (8 models) were designed and manufactured by ourselves from April 1993 to September 2004. After animal experiments, 15 types of different gasless laparoscopic operations were carried out in 87 patients. Results Out of the 87 cases, conversions to open surgery were required in 7 cases (conversion rate, 8.0%). The other 80 cases of gasless laparoscopic operations were successfully performed, involving cholecystectomy, colorectal resection, partial cecectomy, subtotal gastrectomy, inguinal herniorrhaphy, abdominal wall contraction, radical resection for carcinoma of renal pelvis, haital herniorrhaphy with Toupet’s fundoplication and total hysterectomy. Conclusions Our self-made gasless laparoscopic devices may be applied safely and effectively in clinical cases. Gasless laparoscopic surgery has been reflecting the complementary advantages of modern laparoscopic surgery and traditional open surgery. It is of supplementary significance in patients contraindicated to pneumoperitoneum and of distinctive importance for laparoscopic gastrointestinal surgery requiring abdominal fistulization or prolonged incision, as well as hand-assisted hepatobiliary or pancreatic laparoscopic surgery.

Objective To assess the influence of host factors on the progression to cirrhosis in patients with chronic hepatitis C virus (HCV) infection. Methods Duration of 121 patients from HCV infection developing to liver cirrhosis was compared according to age at which HCV was infected, having the history of acute hepatopathy or not, infection pathway and sex. Patients with other hepatitis virus infection were excluded. Age, at which HCV was infected, was identified as that at blood transfusion or acute episode in non-transfusion patients. No patients had applied to any drugs. Results It took mean (27.17?6.78) years for the patients of age range 0-20 at which HCV was infected to develop to cirrhosis, while only (10.16?5.84) years for those of age range 41～50. There were significant differences between them (P0.05). Conclusion Our data show that patients with older age at which HCV was infected, with history of acute hepatopathy or HCV infection through blood transfusion developed into liver cirrhosis in shorter time. Sex was not found to have significant influence on the progression to cirrhosis.

With the increasing incidence and prevalence of male sexual dysfunction, andrologists are more and more in need of accurate and efficient tools to assess therapeutic efficacy and patients' satisfaction and to help patients achieve satisfactory treatment results. This article summarizes some of the most commonly used questionnaires for the diagnosis and assessment of the treatment of male sexual dysfunction, including International Index of Erectile Function (IIEF), Erection Hardness Score (EHS), Quality of Erection Questionnaire (QEQ), Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS), Treatment Satisfaction Scale (TSS), Self-Esteem and Relationship (SEAR), Premature Ejaculation Profile (PEP), Premature Ejaculation Diagnostic Tool (PEDT), Index of Premature Ejaculation (IPE), Arabic Index of Premature Ejaculation (AIPE), Aging Male Symptoms Scale (AMS), Androgen Deficiency in the Aging Male (ADAM), and Symptomatic Inventory for Screening Late-Onset Hypogonadism in Males (SILOH), and presents an overview on their clinical application.

Objective To explore the diagnostic value of plasma fetal DNA level in preeclampsia.Methods Thirty cases of pregnant women with preeclampsia(at 33 weeks and 3 days) and 30 cases of normal pregnant women(at 34 weeks and 3 days) were selected.All the pregnant women carried a male fetus by B-ultrasound,and were sampled at gestational 20 weeks,third trimester and at 1 hour,3 hours,6 hours after delivery.SRY levels in maternal blood were quantitated by polymerase chain reaction(QF-PCR).The endotheliotoxin(ET) level was measured with RIA.Results (1) Mean fetal DNA level of patients with preeclampsia at 20 weeks of gestation was(316?61)copy/ml.They were(266?79)copy/ml,(396?91)copy/ml,(165?43) copy/ml for light and severe preeclampsia women and normal pregnant women,respectively.Maternal blood fetal DNA levels in pregnant women with preeclampsia at 20-weeks of gestation were significantly higher than those normal pregnant women(P

Objective: Fetal monitoring is extremely important in perinatal care. Analysis of cardiotocogragh(CTG) can suppose if the fetus is lack of oxygen, distressed, acidosis, etc. in order to take measures timely. Methods: We have designed Meticare analysis software package to analyze 867 pieces of CTG data, and researched the relationship between short term variation (STV) and basal heart rate(BHR) by statistics, and short time monitoring analysis based on STV. Results: The amplitude of fetal heart rate curve variation(long term variation) tended to decrease when BHR increasing, with the negative correlation and regression equation STV = 9.866-0.02×BHR. Positive correlation exists between 5 and 10 mimute-STV, with the regression equation STV_(10min)=2.861-0.596×STV_(5min).Conclusion: STV calculated by 5 minutes CTG data can forecast the one by 10 minutes data as a reference demanded by Dawes & Redman criterion. If fetal doppler contains STV analysis function, out-patient fetal heart auscultation will be more significant. After 30 weeks pregnancy, with the STV decreasing, fetal distress, asphyxia, low birth weight, and even mortality increasing. BHR increasing should cause attention that STV might decrease, when monitoring with no analysis functional devices or fetal dopplars.

Objective To find out a new treatment method for advanced pancreatic carcinoma. Methods Twenty-nine patients with advanced pancreatic carcinoma and liver metastases were randomly divided into 2 groups.Group A (n=11) underwent bilio-enterostomy and/or gastro-enterostomy combined with systemic chemotherapy after operation;Group B(n=18) underwent bilio-enterostomy and/or gastro-enterostomy combined with peripancreatic arterial ligation and arterial infusion regional chemotherapy.The alleviation of clinical symptom,the change of carcinoma volume by BUS and CT scan,survival period and serum CEA were observed in two groups. Results The symptoms were alleviated apparently in most cases in Group B;BUS and CT scan showed that the tumor volume decreased apparently in Group B;The response rate was 67.7% in Group B,and 18.2% in Group A,respectively(P＜0.01);the mean survival period was (4.8±0.6) months in Group A,and (12.5±1.2) months in Group B,respectively(P＜0.01),there was significant difference between the two groups.The decrease of serum CEA was 54% in Group A and 60% in Group B,but the difference was not significant(P＞0.05). Conclusion Peripancreatic arterial ligation combined with arterial infusion regional chmotherapy is believed to be effective against both pancreatic carcinoma and liver metastases,and it can alleviate the clinical symptoms,postpone the growth speed of tumor,and prolong the survival period.

By analyzing data from a questionnaire survey on bilingual teaching, we evalueted the results of bilingual teaching for seven-year medical students and the main problems of bilingual teaching and solutions accordingly. An uneven English level on the part of teachers and students and imperfect materials etc. affect the overall results of bilingual teaching. Therefore persistent efforts need to be made in enhancing the teachers' English level, improving teaching methods and compiling proper textbooks so as to genuinely improve the bilingual teaching program.
