OBJECTIVE:To find out the incidence and general patterns of drug-induced cardiovascular diseases and to guide rational use of drugs METHODS:By using literature metrological method 646 cases of drug-induced cardiovascular diseases which were reported in Chinese literatures in 1995～2000 were analysed RESULTS:Among those 646 cases,the incidence of arrhythmia was 59 8% The kinds of induced drugs were up to 155 and the most easily inducing one was cardiovascular system drug,which amounted to 37 2%(240/646) Propafenone had the highest incidence of all in inducing cardiovascular diseases(75 cases) There were 35(5 4%) fatal cases mainly caused by cardiovascular system drugs Most of the patients with drug-induced cardiovascular diseases were in middle-age and old age CONCLUSION:To reduce the rate of drug-induced diseases,cardiovascular system drugs should be rationally administrated and stictly supervised

ObjectiveTo develop an assay to quantitatively detect anti-BP180NC16A IgG subclasses and to assess the significance of anti-BP180NC16A lgG in bullous pemphigoid (BP).MethodsThe Glutathione S-transferase(GST)-BPI80NC16A fusion protein was expressed in E.coli system and purified by affinity chromatography.An improved enzyme-linked immunoabsorbent assay (ELISA) was developed and used to detect anti-BP180NCI6A IgG subclasses in serum samples from 10 patients with BP,5 patients with pemphigoid gestationis (PG),1 patient with linear IgA bullous dermatosis (LIBD) and 2 patients with pemphigus.Results The optimal condition for the ELISA was determined by cross assay as follows:the concentration of GSTBP180NC16A fusion protein for coating,500 μg/L; the condition for coating,4 ℃ for 12 hours; the dilution ratio of sera and secondary antibody,1∶ 100 and 1 ∶ 2000 respectively; the condition for incubation,37 ℃ for 1 hour;,the condition for the enzyme-substrate reaction,37 ℃ for 20 minutes.Of the 10 patients with BP,all were positive for anti-BP180NC16A IgG1,9 for IgG2,5 for IgG3,and 9 for IgG4.Anti-BP180NC16A IgG was undetected in any of the serum samples from 2 patients with pemphigus vulgaris or 1 patient with adult LIBD.All the 5 sera from patients with PG; were positive for all the anti-BP180NC16A IgG subclasses,which were predominated by IgGl and IgG3.ConclusionThe developed ELISA is a highly specific and reproducible semiquantitative method for the detection of anti-BP180NCI6A IgG subclasses in patients with BP and PG.

?receptors are particularly abundant in the CNS. ? receptors have been shown to exhibit such a wide variety of actions as modulating glutaminergic, dopaminergic and cholinergic neurotransmission. They also play an important role in maintaining cell growth and proliferation, learning and memory. Recent evidence suggests the possible involvement of ? receptors in the pathogenesis of schizophrenia. More researches are expected to supply new targets for treatment and diagnosis.

Objective:This study aims to explore the relationship between serum response factor (SRF) expression level and gas-tric cancer progression by detecting SRF expression level in cancer cells. Methods:The SRF gene in SGC-7901 cells was silenced by RNA interference. Transfection efficiency was detected by fluorescence microscopy, cell proliferation by CCK 8 method, SRF gene and protein expression level by real-time polymerase chain reaction and Western blot, and cell cycle by flow cytometry. Results:Cell treat-ment with siRNA-SRF induced significant reduction in SRF mRNA levels. Western blot analysis showed that SRF protein decreased by 40.1%in the siRNA group compared with that in the control group (P<0.05). Compared with the blank, negative, and mock transfection control groups, cell proliferation of the siRNA-SRF group decreased. The inhibition ratio reached 64.24%, as measured by the CCK-8 assay (P<0.05). Treatment with siRNA could block SGC-7901 cell cycle at G0/G1 phase (P<0.05). Conclusion:SRF expression is close-ly associated with gastric carcinoma cell proliferation. SRF protein level detection can provide a certain reference value in evaluating malignant gastric carcinoma progression. SRF is possibly an important target for the prevention and control of gastric cancers.

Objective To investigate the use of laparoscopy in the resection of colorectal cancers. Methods A total of 17 cases of colorectal cancer resection had been made by laparoscopy, including 3 cases of right hemicolectomy, 3 cases of sigmoid colon cancer radical resection, 7 cases of Dixon’s procedure, 2 cases of Mile’s procedure and 2 cases of Park’s procedure. The operation was accomplished totally laparoscopically in 6 cases, while the laparoscopic-assisted and hand-assisted excision were conducted in 8 cases and 3cases, respectively. Results All the cases were cured to be discharged from the hospital. There were no deaths or complications or conversions to open surgery.The operation time was 150～240 min (mean, 190 min). The intraoperative blood loss was 20～300 ml (mean, 55 ml). The average length of postoperative hospital stay was 9.6 days. Analgesic was required in 6 cases. Follow-up for 1～6 months found no recurrence. Conclusions Laparoscopic resection of colorectal cancer is safe and feasible,with a satisfactory short-term effect.

To explore the rational use of antibiotics in patients undergoing laparoscopic cholecystectomy(LC).METHODS： The antibiotic use in the selected operation patients was retrospectively studied.230 patients were divided into four groups.A group： Perioperative administration of drug； B group： Preoperative administration for 3 to 7 days and perioperative administration； C group： Perioperative administration and postoperative administration for 2 to 7 days； D group： Preoperative administration for 2 to 7 days， perioperative administration and postoperative administration for 2 to 7 days.Four groups were compared about the efficacy， length of hospital stay and hospitalization expenses.RESULTS： There were no significant differences in efficacy among A， B， C， D and in average length of hospital stay and hospitalization expenses between A and D groups.A group was the lowest in two indices and had the best cost-effectiveness ratio.CONCLUSION： There is clinical significance of preventive antibiotic application in LC patients； perioperative use is the best choice； Cefazolin is the first choice.

miRNA is a kind of endogenous non-coding short RNA. Mature miRNA was formed through the process of shearing and transporting after genetic transcription. miRNA exhibits many important biological functions through regulating expression and translation of target mRNAs. Different miRNAs may act as oncogenes or antioncogenes, and have tissue specificity. The progress of the tumorigenesis is usually accompanied by expression-profile changes of miRNAs. MiRNA regulates many tumor biological behaviors such as differentiation, proliferation, apoptosis, invasion, metastasis, and drug resistance of tumors. Furthermore, some miRNAs have clinical significance in predicting prognosis of tumor patients.
