Objective:To observe the effect of the proteininhibitor of activated STAT 3 (PIAS3) on the proliferation and apopto-sis of U251 glioma cells after PIAS3 expression was inhibited by RNAi. Methods: Three RNAi expression vectorstargeting PIAS3 were constructed and transfected into CHG-5 cells by liposomein vitro. The most efficient RNAi vector was subsequently selected by examiningthe mRNA expressions of PIAS3 in the transfected cells by semi-quantitativeRT-PCR. The selected RNAi vector was then transfected into U251 cells. After 48h of transfection, the mRNA and protein expressions of PIAS3 in glioma cellswere examined by semi-quantitative RT-PCR and western blot. Apoptosis wasobserved by flow cytometry using a double-staining method with FITC-con-jugatedannexin V and PI. Flow cytometry was also applied in cell cycle assay. Results:RNAidownregulated the mRNA (P<0.01) and protein (P<0.01) expressionsof PIAS3 in transfected cells.RNAi promoted the resistance of U251 cells to apoptosisand subsequently al-tered the cell cycle. A high percentage of G2 phaseand a low percentage of Sphase were observed in U251 cells. Conclusion:The down-regulation of PIAS3arrested U251 cells in the G2 phase andinduced the resistance of U251 cells to apoptosis.

Data is the basis and soul of clinical trials. To obtain accurate data, strict and standard data management is essential, which can be effectively supported by quality control in statistical analysis. In this paper, we briefly introduce the concept of the quality control in clinical trials, and describe its contents and methods. We hope that this work will be helpful to the application of statistical quality control in data management of clinical trials.

Objective] To amplify,clone and express of a gene encoding hexose transporter of Plasmodium falcipuram(PfHT1) from Southern China isolate FCC1/HN for studing the immune of recombinant which protective from malaria parasite infection. [Methods] Cultivation of P.falciparum isolate FCC1/HN in vitro; extraction of genomic DNA from FCC1/HN using the alkali specific cleavage method; PCR amplification of PfHT1 and cloning into eukaryotic expression vector, pEGFPN3. The recombinant was introduced into mammalian cells, HEPG2 by using liposome\|mediated transfection. [Results] The gene encoding PfHT1 was specifically amplified from the genomic DNA of P.falciparum isolate FCC1/HN. The size of amplified fragment was 1 516 base pair. The eukaryotic expression recombinant, pN3\|HT1 , was constructed and expressed steadily in the hepatocarcinoma cell lines, HEPG2. [Conclusion] The gene encoding PfHT1 was successfully amplified and cloned. The pN3\|HT1/HEPG2 cell line was built for expressing fusion protein of GFP\|HT1.

OBJECTIVETo investigate the regulation of Cha Gan Beng Ga on the activity of biomarker PGC-1α in vivo and in vitro, and lay the foundation for studying the efficacy result of Cha Gan Beng Ga on xenograft tumor model and extracting active constituents.

METHOD(1) The coarse powder of Cha Gan Beng Ga was extracted with 70% ethanol solution through heating and refluxing, and finally was used to freeze dry powder. (2) 50 mg x kg(-1) of freeze-dried power was orally administrated to KM and C57BL/6J mice once daily, lasting for 5 consecutive days; different concentrations of extracted materials was given to non-small cell lung cells A549. (3) The expression level of PGC-1α mRNA was quantitatively determined in lung tissue of mice and non-small cell lung cells A549.

RESULTThe expression levels of PGC-1α in lung tissue of different mice strains had an increasing tendency. Furthermore, the expression levels of PGC-1α in non-small cell lung cells A549 also had an increasing tendency, showing dose and time-dependent relationships.

CONCLUSIONMongolian Medicine Cha Gan Beng Ga could induce the over-expression of PGC-1α mRNA in lung tissue of mice and in non-small cell lung cells A549. The present results will lay foundation for studying the efficacy result of antitumor and active constitutes in future.

Objective To compare the outcomes of homeopathic bidirectional-traction reduction device and traction table in surgical treatment of femoral intertrochanteric fractures.Methods A retrospective case control study was made on 94 cases of femoral intertrochanteric fractures treated from July 2015 to December 2015.There were 26 males and 68 females,aged 60-75 years.According to the Evans classification,the fractures were type Ⅱ in 24 cases,type Ⅲ in 32 and type Ⅳ in 38.Fifty-seven cases sustained chronic diseases.According to the random number table,the subjects were assigned to receive homeopathic bidirectional-traction reduction (homeopathic reduction group,48 cases) and traction table reduction (control group,46 cases).All fractures were fixed with proximal femoral nail antirotation.Operation time,reduction time,tluoroscopy time,blood loss and rate of closed reduced cases were recorded.Fracture union and rotation of the affected femur to the tibia were detected after operation.Functional outcome was evaluated using the Harris score at the final follow-up.Results All fractures were reduced closely in homeopathic reduction group,while 15 fractures in control group were reduced via a small-incision anterior approach.Operation time,reduction time and fluoroscopy time in homeopathic reduction group were (62.9 ± 12.1) min,(6.8 ± 1.5) min and (11.3 ± 5.6) s respectively,significantly less than the corresponding data in control group (all P ＜ 0.05).One month after operation,rotation of the affected femur to the tibia was (2.8 ± 1.2) ° in homeopathic reduction group,significantly less than that in control group [(11.5 ± 4.7) °] (P ＜ 0.05).Bone union was observed in all cases.At the final follow-up,Harris hip score was (92.6 ± 7.6)points in homeopathic reduction group,significantly higher than that in control group [(87.3 ± 6.5) points] (P ＜ 0.05).Conclusion For the elderly patients with intertrochanteric fractures,homeopathic bidirectional-traction device has advantages of high rate of closed reduction,shorter operation time,less radiological exposure and satisfactory function recovery of the affected hip joint.

A.Conclusion The inhalation of yellow phosphorus and its compounds in rats may induce intoxication of rats with manifestations of ALI/ARDS.Xuebijing injection and decadron have therapeutic effects on such intoxication,then Xuebijing injection combined with both decadron can decrease decadron dosage.
