Objective To preliminarily investigate curative effect of hepatic arterial perfusion of p53 gene in the therapy of advanced hepatocellular carcinoma.Methods Tirty cases of advanced hepatocellular carcinoma were divided into experimental group and control group,p53 gene was perfused into target artery confirmed by angiography.In experimental group,10~(12)Vp of p53 gene and 20 mg OPT were employed every week as a course for 21 days and 1 to 4 courses time the cases of the study.In control group,only 20 mg OPT was used.Results The survival period was 14 to 405 days in experimental group and 18 to 167 days in control group.There was a significant difference between the two groups(P＜0.05). Conclusion p53 gene is efficacious in the therapy of advanced hepatocellular carcinoma.(J Intervent Radiol,2007,16:127-129)

Garcinia plants are one of the rich sources of natural xanthones and benzophenones which have attracted a great deal of attention from the scientists in the fields of chemistry and pharmacology. Recently, many structurally unique constituents with various bioactivities, especially anti-tumor activity, have been isolated from Garcinia plants. This concise review focused on the anti-cancer activity natural products isolated from Chinese Garcinia plants, and the research finding by authors and collaborators over the past several years were cited.

The complete genomes of more cyanobacterial strains have been completed for sequence, and genetic engineering of cyanobacteria has evolved in the post-genome era. Since Kaneko and colleagues had completed the sequence for the complete genome of Anabaena sp. PCC 7120 in 2001, functions of some genes in this genome, including fructose-1,6-bisphosphate aldolase (FBA) gene, have been predicated using the method of bioinformatics. However, little information is available regarding whether this gene can encode FBA and its product characteristics of related enzyme. Here, to explore this information, the predicted II-FBA gene-encoding region in Cyanobase database was cloned by PCR method and then ligated into pET-32a to generate the expression vector, pET-FBA-II. The results of SDS-PAGE indicated that the expression level of the expected target polypeptide was approximate 23.4 percent as compared to total protein and the molecular weight is about 40 kDa as compared to the protein molecular marker. The results of enzyme activity analysis showed that the activity of II-FBA was ~11.8 U per mg protein and owned a standard activity of II-FBA. To sum up, the results not only prove the functional prediction of this II-FBA gene from the Cyanobase database, but also provide the important conditions for further studying its physiological and biochemical characteristics and functions of the gene expression product.

Objective To study the efficacy and safety magnesium sulfate for the treatment of adult severe tetanus.MethodsTwenty-seven inpatients with adult severe tetanus during April 2005 - October 2010 were retrospectively analysed.ResultsThe total serum magnesium more than 4 mmol/L was found in 2 patients ( 2/27,7.40％ ).The tracheotomy was performed in 25 Patients (25/27,92.6％),22 of which (22/25,88.0％) run mechanical ventilation with the mean mechanical ventilation time (7.5 ± 3.7 ) days,(4 to 16 days).Pulmonary infection occurred in 25 cases (25/27,92.6％).Twenty-three of 27 (23/27,85.2％ ) cases were cured except 4 cases died,and the mean hospital stay was (32.22 ± 18.78) days,(25to 48) days.Conclusions20％ magnesium sulfate is safe for treatment of the patients of adult severe tetanus.It can control not only muscle rigidity and spasms but also autonomic instability efficaciously,and lower the dosage of sedative such as diazepam and chlorpromazine.This method is worth popularizing in clinical practice for its easy operation and low cost.

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.

OBJECTIVE To investigate the point prevalence of nosocomial infection(NI) and discover the problems in the management of NI in a hospital.METHODS A team of surveyors were trained to inquire history of illness,do physical examination for inpatients and collect some necessary data from medical records on a single day.Questionnaires about NI cases were filled out and analyzed.RESULTS From 1500 patients,1493(99.53%) patients were investigated,the point prevalence and case prevalence of NI were 5.69% and 6.03%;the highest prevalence appeared in internal medicine at 8.54%;lower respiratory tract infections accounted for 38.89%;the detection rate of multi-drug resistant(MDR) bacteria was 49.23%;antimicrobial utilization rate was 48.69%.CONCLUSIONS The prevalence survey is a rapid and efficient method,which could offer evidence of target surveillance of NI.

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 value of polysomnography (PSG) and ApneaGraph (AG200) in the diagnosis evaluation of obstructive sleep apnea hypopnea syndrome (OSAHS). METHOD: From January to December in 2012, 67 OSAHS patients diagnosed by PSG were examined by AG200. The apnea hypopnea index (AHI), hypopnea index (HI), apnea index (AI), the lowest oxygen saturation (LSaO2) was were detected and the results were analyzed statistically. RESULT: Significant differences were observed in AI, AHI, LSaO2 between AG200 and PSG (P < 0.05, respectively). No statistically significant difference was found in HI. The differences in HI between AG200 and PSG were not significant (P > 0.05). AHI, HI and LSaO2 was were significantly correlated between AG200 and PSG (r = 0.870, 0.743, 0.374, 0.716, P < 0.01). CONCLUSION AG200 could not replace PSG but could identify the level of upper airway obstruction.
