Recurrent miscarriage is a common disease in clinical obstetrics and gynecology. There is no curative treatment for recurrent miscarriage in conventional medicine. Traditional Chinese medicine (TCM) has been widely used in the treatment of recurrent miscarriage in China for thousands of years. However, randomized controlled trials (RCTs) with high quality evaluating the effectiveness and safety of Chinese herbal medicine (CHM) still lack. This study was conducted in order to identify methodological problems in published or unpublished RCTs of CHM in the treatment of recurrent miscarriage, and provide suggestions for TCM researchers to conduct high-quality clinical research.

Objective To construct an recombinant adenovirus vector of vascular endothelial growth factor small interfering RNA(Ad5-VEGFsi) and to observe its inhibitory effect on the cell proliferation of human leukemia K562 cells. Methods The specific human VEGF siRNA was subcloned into the shuttle plasmid pSES-HUS and then cotransfected with plasmid pAdeasy-1 to produce pAd5-VEGFsi by homologous recombination. The identified recombinant plasmid pAd5-VEGFsi was packaged and amplified in 293 cells. At 72 h after the transfection of Ad5-VEGFsi into K562 cells, VEGF mRNA expression and the protein level of VEGF in the cell culture supernatant were determined by RT-PCR and ELISA, respectively. Cell proliferation was measured by MTT assay and cell apoptosis by flow cytometry. Results The recombinant adenovirus Ad5-VEGFsi was successfully constructed. Ad5-VEGFsi with the titer of 4.6?1011 pfu/ml was harvested by CsCl gradient purification. Compared with those in the control, EGF mRNA in cells decreased by 66.55% (P

Objective To discuss effects of anti-inflammatory mechanism of amygdalin on rats with type II collagen-induced arthritis (CIA). Methods Wistar rats were randomized into normal group, model group, amygdalin group, and tripterygium group. Type II CIA rat models were established. From the 15th day after the modeling establishment, each administration group was given corresponding dose of medicine for continuous 28 days. Levels of TNF-αand sICAM-1 were detected by ELISA in serum of rats, and expression of TNF-α was detected by immuno-histochemical method. Results TNF-α positive expression in amygdalin group and tripterygium group was similar and significantly reduced compared with model group. Levels TNF-α and sICAM-1 in amygdalin group and tripterygium group significantly decreased compared with those in model group (P<0.05), without significant difference compared with normal group (P>0.05). Conclusion Amygdalin can inhibit the expression of TNF-α and levels of TNF-α and sICAM-1, in order to treat rheumatoid arthritis.

Medical postgraduates are the future core force of clinical diagnosis and treatment,scientific research,education and sanitary administration.Therefore,to cultivate qualified professionals,the key of contemporary medical postgraduate education is to pay more attention to comprehensive quality training in order to make students adapt to the continuous development of society and medical model.The First Clinical College in Wuhan University has implemented the hospital administration internship in combination with social needs and explored the education model of contemporary medical students with comprehensive quality.

Teacher's career development in British medical school has experienced a very long process from establish to gradually mature.So far,it has already set up its system and its own characters in strategy and teacher's self-development.By analyzing characters of teacher's career development in British medical school including teacher development center,teacher's self-development and assessment for medical educators,we aimed to raise enlightenments on teacher's career development in China.

OBJECTIVE:To investigate clinical efficacy and safety of goserelin in the treatment of adenomyosis complicated with severe dysmenorrheal before placing levonorgestrel intrauterine system (LIS). METHODS:A total of 140 adenomyosis pa-tients with severe dysmenorrheal were selected from Sanya Family Planning Technology Service Center during Jan. 2014-Jan. 2016, and then divided into control group and observation group according to lottery method,with 70 cases in each group. Both groups re-ceived LIS within first 7 d of menstruation,and observation group was given Goserelin acetate sustained-release implant 10.8 mg subcutaneously via anterior abdominal wall one week before placing. Therapeutic efficacy was evaluated 6 months later. The im-provement of dysmenorrhea was compared between 2 groups. The uterine volume,COX dysmenorrhea score (CMSS),menstrual volume,hemoglobin (Hb) and CA125 content were compared between 2 groups before and after treatment. The occurrence of ADR was also compared. RESULTS:The rate of dysmenorrheal improvement in observation group was 95.71％,which was signifi-cantly higher than 81.43％of control group,with statistical significance(P<0.05). Before treatment,there was no statistical signif-icance in above indexes between 2 groups (P>0.05). Compare to before treatment,CMSS score,menstrual volume and CA125 content of 2 groups were decreased significantly after treatment,while Hb content was increased significantly;the observation group was significantly better than the control group,with statistical significance(P<0.05). There was no statistical significance in uterine volume between 2 groups before and after treatment (P>0.05). There was no statistical significance in the incidence of ADR(10.00％ vs. 14.29％)between 2 groups(P>0.05). CONCLUSIONS:Goserelin in the treatment of adenomyosis complicated with severe dysmenorrheal before placing LIS can effectively relieve dysmenorrheal,reduce menstrual volume and improve Hb and CA125 levels,but do not increase the risk of ADR.

0.05).Meanwhile,the cardiac function and the quality of life of the rehabilitation exercise group was improved to a significantly larger extend than those of the control group (P

AlM:To construct recombination eukaryotic expression plasmid of human thyrotropin receptor extracellular domain encapsulated with cationic liposomes.
METHODS:We amplified the target gene of shuttle vector PHMCMVTSHR289, conjugated the target gene and eukaryotic expression plasmid pcDNA3. 1 +, and accredited whether pcDNA3. 1+/TSHR289 was connected or not by enzymatic digestion and sequencing.

OBJECTIVETo investigate clinical outcomes of Kirschner wire as blocking screws combined with interlocking intramedullary nail internal fixation in treating tibial metaphyseal fractures (AO 43A).

METHODSFrom March 2011 to June 2012, 9 patients with tibial metaphyseal fractures were treated with blocking screws Kirschner wire combined with interlocking intramedullary nail, including 7 males and 2 females aged from 23 to 54 years old with an average of 37.4. Postoperative complications, X-ray were observed, AOFAS scoring were used to evaluate function after operation at 12 weeks.

RESULTSAll patients were followed up from 6 to 40 weeks (mean 20.1), and healed at stage I. No serious swelling, infection and skin necrosis occurred. No fracture instability and displacement appeaered at 4 and 8 week after operation. AOFAS score was (95.2±4.6) at 12 weeks after operation and 7 patients gained excellent result and 2 patients good.

CONCLUSIONKirschner wire as blocking screws with interlocking intramedullary nail for treatment of tibial metaphyseal fractures can fix well and perform simply.

A high-throughput method for screening drug multi residues was developed by quadrupole-time-of-flight( Q-TOF) mass spectrometry together with QuEChERS sample preparation technique. It has been used for the determination of 57 drugs, such as tetracyclines ( TCs ) , sulfonamides ( SAs ) , quinolones ( QNs ) , triphenylmethanes (TPMs), estrogens (ETs), androgens (AGs) and glucocorticoids (GCs) in fish. The optimized pretreatment conditions were examined. The target compounds were extracted with acetonitrile under the condition of Na2 EDTA-Mcllvaine buffer, and the usage of clean-up reagents was 25 mg anhydrous magnesium sulfate, 12. 5 mg octadecylsilane and 6. 25 mg N-Propylethylenediamine sorbent for extracted solvent of each milliliter. The positive results acquired by this high-throughput method were confirmed by liquid chromatography-tandem mass spectrometry ( LC-MS/MS) . The detection limit for these 59 drugs was in the range of 0. 5-5. 3 μg/kg. The method is time-saving, convenient, effective and wide coverage. Its sensitivity can meet the requirement of the detection of drug residues in aquatic products.
