The p53 gene is one of the most common targets for genetic abnormalities in human tumors. Restoring wild - type p53 gene (wt-p53) into cancer cells which have p53 deletion is a strategy in cancer gene therapy. In order to explore the feasibility of this hypothesis, we selected a gastric cancer cell line BGC823 which was confirmed having deletion of chromosome 17pl3 and decreased expression level of p53 mRNA . We transfected construct pC53SN3 containing wt - p53 into BGC823 cell line with lipofectin mediated gene transferration, and G418 resistant colonies were characterized by using analysis of PCR, Southern blot hybridization, Northern blot hybridization and Western blot hybridization. These data showed that exogenous wt-p53 had successfully transferred into BGC823 cells and obtained high expression. The cell growth rates in regular medium and soft agar were inhibited from 30 to 40 percent in the BGC823 cells transfected with wt - p53. The tumorigenicity in nude mice showed that one of four mice failed to form tumor and three of them delayed to form tumor from 7 to 14 days comparing with monk and parent BGC823 cells. These results suggested that exogenous wt -p53 could suppress the growth ability and tumorigenicity of human gastric cancer cells. The method of using lipofectin mediated wt-p53 gene transfection may have a potentially therapeutic effect on human gastric cancer.

Objective To evaluate the accuracy of lung volume in pneumothorax by CT.Methods 1.17 artificial lung models were scanned by SHIMADZU SCT-7000 TH whole body scanner system and their volumes were determined by using the volume-calculated function of CT.2.The actual volume of the models were equal to the volume of water injection by the models.Results The actual and calculated volumes of lung were 2893.47?29.22 ml and 2894.32?28.47 ml respectively.A good correlation(?=0.9860,?

An isocratic high-performance liquid-chromatographic method is-described for the simultaneously determining carbamazepine and its biologically active metabolite, carbamazepine-10, 11-epoxide. Serum samples containing an internal standard (10-methoxycarba-mazepine) are extracted with dichlor-methane and 4 mol ? L-1 sodium hydroxide. The organic extract are evaporated at ambient temperature under a stream of nitrogen. The residues are reconstituted in mobile phase and injected on to a re-versed-phase C18 Column (150?4. 6mm I. D). The mobile phase consists of ace-tontrile/methanol/water (50/210/260 by vol) . The UV detector is operated at 214nm. The elution times of all com-pounds are within 7 min.The least detectable concentrations of carbamazepine and carbamazepine-10, 11-epoxide are 0. 08mg ? L-1 and 0.1mg ? L-1, respectively. The average absolute recovery for carbamazepine is 96.0% and for carbamazepine-10,11-epoxide is 97.3%. Within-run CV is 3. 3%~5.7%. and between-run CV is 4.3%~9.0%. The standard curve is linear at least within 40mg ? L-1 for carbamazepine and within 20mg ? L-1 for carbamazepine-10, 11-epoxide.

OBJECTIVE:To evaluate the sedative and analgesic effects and safty of fentanyl-propofol and midazolam-propofol by intravenous injection in gastroscopy for aged-patients.METHODS:128aged-patients were randomly divided into3groups:fentanyl-propofol group(groupⅠ),midazolam-propofol group(groupⅡ)and ordinary gastroscopy group(groupⅢ).The effects of sedation and analgesia and the variation of SBP,HR and SDNN were observed.RESULTS:Patients in groupⅠandⅡfelt much less discomfortable than those in groupⅢ(P

The bcr-abl negative myeloproliferative neoplasms (MPN) include polycythemia vera (PV),essential thrombocythemia (ET) and primary myelofibrosis (PMF).Along with the detecting of JAK2 V617F gene mutation in MPN patients,a series of small molecules drugs that targeted to the mutation have been investigated in clinical trials.Ruxolitinib is the inhibitor of JAK1/2,which has been proved by USA Food and Drug Administration (FDA) and the European Medicines Agency (EMA) to treat patients with intermediate-2 or high-risk PMF or post-PV MF or post-ET MF and PV patients who are intolerant or resistant to hydroxycarbamide,attributed to a number of clinical trials,especially in COMFORT-Ⅰ and COMFORT-Ⅱ.As a result,the MPN patients have new hope for the treatment.

Objective:To observe the efficacy of acupuncture-moxibustion therapy in treating urinary retention after surgery for cervical cancer. Methods:Fifty eligible patients were randomized into a treatment group and a control group by their visiting sequence, 25 in each group. The control group was intervened by indwelling urethral catheter after gynecological surgery; while the treatment group started to receive acupuncture-moxibustion and cupping treatment at the 7th day after surgery, in addition to the intervention given to the control group. The residual urine volume and total effective rate of the two groups were detected. Results:After 7-day treatments, the total effective rate was 92.0% in the treatment group versus 72.0% in the control group, and the difference was statistically significant (P<0.05). Conclusion:Acupuncture-moxibustion treatment plus cupping based on the conventional intervention is effective for urinary retention after surgery for cervical cancer, worth promoting in clinic.

Objective:To establish the determination method for total flavonoids in Cyperus rotundus and investigate the total fla-vonoids content in Cyperus rotundus from different habitats. Methods:Total flavonoids in Cyperus rotundus from different habitats were detected by ultraviolet spectrophotometry with rutin as the standard substance. Results:The absorbance of rutin had a good linear cor-relation with the concentration within the range of 0.064 3-0.642 6 mg·ml-1(r =0.999 1). The average recovery was 99.74%(RSD=2. 16%,n=6). The order of total flavonoids content in Cyperus rotundus from different habitats was Henan province >Sichuan province> Guangdong province >Anhui province > Halnan province >Shandong province. Conclusion:The method is easy and ac-curate, which can be applied in the quality control of Cyperus rotundus. The total flavonoids content in Cyperus rotundus from Henan province is the highest.

OBJECTIVE:To provide reference for the timely and accurate judgment of drug fever induced by Piperacillin sodi-um and tazobactam sodium for injection and rational drug use in the clinic. METHODS:The medication,clinical manifestations, laboratory examination results and the physician treatment of 30 inpatients with drug fever induced by Piperacillin sodium and tazo-bactam sodium for injection from Sept. 2013 to Sept. 2014 were analyzed retrospectively and statistically. RESULTS:Most of the drug fever induced by Piperacillin sodium and tazobactam sodium for injection occurred in continuous 7 to 14 d medication,and the cumulative dosages were between 1.3 to 2.7 g/kg;73.3% of the 30 patients had fever during the intravenous drip,with body temperature mainly≥38.5 ℃;the elevation of eosinophil and slightly increase of serum C-reactive protein (CRP) and blood cell sedimentation rate (ESR) could be used as observation indexes of drug fever,but the leucocyte reduce could’t be suitable;the body temperature dropped to normal within 24 to 48 hours after stopped using it. CONCLUSIONS:The drug fever induced by Piperacillin sodium and tazobactam sodium for injection has no correlation with the patients’gender or age,and no special diagnos-tic criteria. But it has certain correlation with duration of medication,cumulative days and dosages and it can be used as reference of judgment with the combination of hematological examination index. Clinicians should improve the understanding and attention about drug fever to stop using suspicious drug in time.
