OBJECTIVE:To analyze intervention effect of Drug Rational Usage Guidelines System(DRUGS)on antibacterial agents use in department of obstetrics and gynecology in our hospital. METHODS:The application of antibacterial agents in depart-ment of obstetrics and gynecology in our hospital during Jan.-May(before intervention)and Jun.-Nov. 2012(after intervention)were extracted in respects of drug name,preoperative medication duration,perioperative additional condition,postoperative drug with-drawal time,drug combination,usage and dosage,average hospitalization stay,hospitalization cost. The intervention effects were analyzed. RESULTS:After intervention,the type of antibacterial agents were more in line with national regulations;the proportion of type Ⅰ incision surgery without antibacterial agents increased from 57.8% to 75.2%;the prophylactic application of antibacteri-al agents in type Ⅱ incision surgery within 0.5-2 h increased from 80.2% to 97.0%. The rate of reasonable antibacterial selection, drug combination,usage and dosage increased from 76.9%,64.9%,71.3% to 89.3%,84.6%,90.2%,respectively. The average hospitalization stay and antibacterial cost per capita decreased significantly. There was statistical significance among above indica-tors before and after intervention(P<0.05 or P<0.01). CONCLUSIONS:DRUGS effectively change irrational use of antibacterial agents in department of obstetrics and gynecology,which provide a new method for the management of antibacterial agents.

Previous studies have shown that ginsenoside Rb1 (Rb1), one of active components in ginseng, can activate insulin signaling pathway and promote translocation of glucose transporters (GLUTs) to increase glucose uptake in adipocytes. However, the effect of Rb1 on the expressions of GLUTs remains unknown. In this study, the effects of Rb1 on GLUT1 and GLUT4 were observed in 3T3-L1 adipocytes and epididymal adipose tissue of db/db obese diabetic mice. Male db/db mice were treated with Rb1 by intraperitoneal injection at the dosage of 20 mg x kg(-1) for 14 d. Rb1 reduced HOMA-IR significantly (P < 0.05, n = 5), and FBG and FINS sowed declining trend after treatment with Rb1. Rb1 recovered the expressions of GLUT1 and GLUT4 and phosphorylation of AKT in adipose tissue of db/db mice. In vitro, glucose consumption in 3T3-L1 adipocytes treated with 10 micromol x L(-1) Rb1 for 24 h was elevated (P < 0.05, n=3), and mRNA of GLUT1 and GLUT4 were up-regulated (P < 0.05, n=3) and proteins of GLUT1 and GLUT4 were also increased. AKT was activated in adipocytes treated with Rb1 for 3 h. It can be concluded that ginsenoside Rb1 can up-regulate the expression of GLUTs in adipose tissue, in addition to activate insulin signalling pathway, which may partially account for its insulin sensitizing activity and regulating effect of glucose metabolism.

Purpose:To investigate the efficacy of infusion gemcitabine via artery port and catheter system (PCS) for advanced pancreatic cancer.Methods:57 cases advanced pancreatic cancer proved by pathology were implanted Implantofix PCS.The number of ports implanted subcutaneously in inferior right abdomen and subcutanceusly in inferior chest was 48 and 9 cases respectively.The first total does in experience group was gemcitabine 3.0,5-FU 3.0,IL-2 6 million u via three times infusion.Results:The overall implanted successful rates was 100% and indwelling catheter tip dislocation rate was 0. Two PCS were pulled out in 2 fat old female patients because of bad wound healing after two months.In the experimental and control group according to the standard of clinical benefit-responces were 37 and 20 respectively.The obvious improve- ment in pain in experimental and control group was 27.2% and 4.8%,respectively.The duration of clinical benefit-re- sponces were 18 weeks in experimental groups,13 weeks in control group.The midian survival in experimental group was 6.25 months,4.41 months in control group.The 6-,9-,12-months survival rates in experimental group were 46%,24%, 18% more thans 31%,6% and 2% in control group.Conclusions:Infusion gemcitabine via artery PCS can not only relieve pain,prolong survival rate but also provides a long-term intra-arterial chemotherapy and effctive access for advanced pancre- atic cancer.

Objective To study the clinical characteristics and curative effects of pancreatic cystade- nocarcinoma in order to improve its diagnostic and therapeutic accuracy.Methods A retrospective analysis was done on the clinical materials of 13 cases of pancreatic cystadenocarcinoma hospitalized in Shanxi Cancer Hospital from 1990 to 2006.Results The preoperative diagnosis were as follows:pancreatic cystadenocarci- noma 6 cases,pancreatic cystadenoma 2 cases,pancreatic cancer 1 case,pancreatic pseudocyst 4 cases.The misdiagnosis rate was 53.8 %.Surgical operation was done on the 13 cases,and 10 of them were treated by radical operation.A 5-year follow-up was done on 6 still alive cases,and 1 of them lived over 11 years.3 cases were treated by palliative operation,and all of them died within 3 years.Conclusion Since there is no specific clinical manifestations of pancreatic cystadenocarcinoma,it is very difficult to get an accurate preop- erative diagnosis.Radical operation is the most effective therapeutic methods.

BACKGROUND: Polymorphism in promoter region can change the expression of genes, which may be associated with susceptivity of diseases. Gene polymorphism of interleukin-6 (IL-6) promoter is associated with nationality and many diseases. Different nationalities often display different characteristics of gene polymorphism.OBJECTIVE: To observe the distribution of polymorphism at sites -597 and -572 in IL-6 promoter region in Tibet Tibetan population and to provide the theoretical data for Tibetan population genetics and background of immunity.DESIGN: Randomized investigation.SETTING: Institute of Anthropology, Jinzhou Medical College.PARTICIPANTS: Totally 108 healthy Tibetan teenagers were selected from Lasa and Naqu region in Tibet autonomous region from October 2003 to July 2004, including 60 males and 48 females, aged from 14-21 years. Inclusive criteria:The parents of the volunteers were healthy Tibetans after body examination. The volunteers knew the fact, agreed to participate into the trail and signed the informed consent.METHODS: 5 mL peripheral vein blood was collected from 108 Tibetan teenagers. DNA from human leucocytes was extracted by salt fractionation. IL-6 promoter including -597 and -572 fragments was amplified by polymerase chain reaction (PCR). Representative fragments were cloned then sequenced after restriction fragment length polymorphism (RFLP).MAIN OUTCOME MEASURES: Distribution of polymorphism in Tibet Tibetan population; Results after comparison with those of other nationalities including Han population.RESULTS: Data of 108 Tibetan teenagers were involved in the result analysis. ①Distribution of polymorphism on -572C/G site of IL-6 promoters in population of either sex: There were no GA and AA genotypes at site -597, but only GG genotype appeared. There were CC, CG and GG genotypes at site -572, and the frequencies were 0.63, 0.35 and 0.02 in order. Distribution of genotype with representativeness met the Hardy-Weinberg equilibrium. Allele frequencies were 0.81 and 0.19, respectively. There was no significant difference of either sex in genotype and allele frequency (P ＞ 0.05). ②Distribution of polymorphism on -597 G/A and -572 C/G in different nationalities: GG, GA, AA genotypes appeared on -597 site in England and France, and G and A allele frequencies were 0.60 and 0.40,respectively. It was significantly different from that of Tibetan in Tibet. Furthermore, Japanese had no polymorphism,which was similar to that of Hans in China (P ＞ 0.05). ③Genotype of different straps and results of DNA sequencing:Only GG genotype was found on -597 site (without the restriction site, one fragment after restriction, PCR amplification products), no GA and AA genotypes. CC, CG and GG genotypes appeared at site -572, and frequencies were 0.64,0.35 and 0.01, respectively. Distribution of genotype with representativeness met the Hardy-Weinberg equilibrium (P ＞0.05). Allele frequencies were 0.81 and 0.19, respectively. There was no significant difference of either sex in genotype and allele frequency. Distribution of gene frequency and allele frequency in IL-6 were similar between Tibetan and that of Hans, but it was significantly different from that of population in England, France and America.CONCLUSION: There are nationality differences of IL-6 gene polymorphism at sites -597 and -572. No polymorphism is found at site -597 in Tibetan. Race differences are seen at site -572, having CC, CG and GG genotypes and G allele is rate. Compared with white population, there is significant difference in genotype and allele frequency at site -572. Their characteristics are close to Hah population and Japanese, which may be associated with genetic gene of persons living in plateau.
