OBJECTIVETo observe the effect of sodium tanshinone II (A) sulfonate (STS) on Ang II -induced atrial fibroblast collagen synthesis and TGF-beta1 activation.

METHODAtrial fibroblasts of neonatal rats were cultured to determine the content of collagen protein. The original synthesis rate determined by the [3H]-proline incorporation method was taken as the index for myocardial fibrosis. The content of active TGF-beta1 and total TGF-beta1 in cell culture supernatants were tested and cultured by ELISA. The expression of thrombospondin-1 (TSP-1) was assessed by using Western blot.

RESULTAng II could significantly increase the content of atrial fibroblast collagen and the collagen synthesis rate, the TSP-1 expression and the concentration of active TGF-beta1, without any obvious change in total TGF-beta1. After the STS treatment, all of the indexes, apart from total TGF-beta1, were obviously down-regulated.

CONCLUSIONSTS could decrease the secretion of Ang II -induced atrial fibroblast collagen and the synthesis rate. Its mechanism is related to the inhibition of TSP-1/TGF-beta1 pathway.

The DNA fragment RM07 was isolated from halophilic archaea Halobacterium halobium, which can function as promoter not only in halophilic archaea, but also in Escherichia coli as eubacterial promoter. Sequencing analysis indicated that it possessed the typical consensus sequences (-35 and -10) of bacterial gene promoter, which was confirmed by further deletion analysis: With its -35 sequence deleted and -10 sequence left,DNA fragment RM07a nearly cannot initiate transcription;With its both -35 and -10 sequences,RM07b DNA fragment could be active as promoter at a level even higher than RM07. Our research also showed that the promoter function of RM07 fragment in Escherichia coli was under the control of environmental factors,especially its positive correlation with the increasing concentration of sodium chloride. Therefore, RM07 DNA fragment may be potential1 novel promoter source for constructing double-function vectors. It also has special significance in elucidating the issues of the fusing characteristics of archaea and lateral gene transfer between archaea and bacteria.

OBJECTIVETo analyze the related factors of the infection after operation of open tibiofibula fractures.

METHODSThe clinical data of 141 patients with open tibiofibula fractures underwent surgical treatment from June 2009 to December 2012 were retrospectively analyzed. All the patients were male and aged from 18 to 61 years old with an average of 39.2 years; all the fractures were unilateral. According to Gustilo typing of fracure, 5 cases were type I, 44 cases were type II, 27 cases were type III a, 56 cases were type III b and 9 cases were type III c. These clinical data included patients' age, gender, body mass index (BMI), underlying diseases, time of operation, fracture site, fracture type, fixation method, postoperative drainage, debridement condition and so on. The postoperative infection conditions were recorded, and the correlation between above factors and infections were analyzed. Finally, the significant related variables were introduced into a Logistic regression model to evaluated their risk.

RESULTSAmong the 141 patients, 22 cases developed with infection (15.6%). The significant relative factors with infection contained fixation method, debridement condition, underlying diseases and postoperative drainage (P < 0.05). The correlativities were stepped up in order, their odds ratios value was 2.451, 3.164, 3.414, 5.117, respectively.

CONCLUSIONActive treatment for underlying diseases before operation, thorough debridement for open wound, suitable fixation method for fracture and thorough draining are effective measures in preventing postoperative infection.

Objective To know the current situation of nurses' physical activity and the influencing factors, and to provide the theoretical evidence for nurses to better develop the activities of sport. Methods 500 nurses were investigated using a self-designed questionnaire, with reference to a lot of recent related articles.Results Nurses were short of conscionsness of physical activity, and the nurses attended the physical activity were lesser in quantity and frequency. Nurses were lack of scientific and systematical guidance, and had less knowledge about salubrious exercise. Conclusions Nurses' status of taking part in the physical activity should be regarded. It is suggested that the correlative departments should adopt some active measures to encourage nurses join in all kinds of sports, thereby improving the nurses' constitution and helping patients recover and maintain health.

BACKGROUNDThe conventional procedure for screening bioactive components from traditional Chinese medicine is time-consuming, expensive and low efficient. Therefore, some alternative strategies are needed urgently. A novel method for screening anti-platelet aggregation components from oleoresins was developed using chicken thrombocyte extract and high performance liquid chromatography.

METHODSThe anti-platelet aggregation components of oleoresins were combined with receptors, channels and enzymes of chicken thrombocytes under physiological environment. Unbound substances were washed away and bound compounds were eluted using specific phosphate buffered solution (PBS). Compounds released from target sites were collected and analyzed by high performance liquid chromatography and LC-MS. The activity of three compounds which were screened from this model was confirmed using platelet aggregation pharmacology in vivo.

RESULTSThere were four typical compounds that bound to the thrombocytes: 6-gingerol, 8-gingerol, 6-shogaol and 10-gingerol, and all had shown anti-platelet aggregation activities. Eight-gingerol displayed the best anti-platelet aggregation effect.

CONCLUSIONSChicken thrombocyte extract can be used to isolate chemicals that are ligands of the receptor or other bio-targets on the platelet. This may therefore be a simple and efficient method to screen for anti-platelet aggregation compounds from traditional Chinese medicine.

OBJECTIVETo evaluate the efficacy and safety of etanercept plus Tripterygium wilfordii polyglycoside (TWP) in elderly patients with active rheumatoid arthritis (RA).

METHODSTotally 46 elderly patients with active RA were randomly assigned to the treatment group (22 cases) and the control group (24 cases). All patients received subcutaneous injection of etanercept, 25 mg each time, twice per week. The dosage was reduced to once per week 3 months later. Patients in the treatment group took TWP Tablet (10 mg each time, three times per day), while those in the control group took methotrexate (MTX), 10 mg each time, once per week. The whole course lasted for 24 weeks. Patients' rest pain, tender joint number, swollen joint number, health assessment questionnaire (HAQ), patients' global assessment, physicians' global assessment, erythrocyte sediment rate (ESR), C reactive protein (CRP), rheumatic factor were assessed at week 0, 4, 8, 12, and 24. The curative effect was statistically evaluated by the United States Institute of Rheumatology ACR20, ACR50, and ACR70 improvement criteria. Meanwhile, any adverse event was recorded and evaluated.

RESULTSTotally 41 completed the trial, and 5 dropped off (3 in the treatment group and 2 in the control group). Compared with the control group, there was no statistical difference in ACR20, ACR50, or ACR70 in the treatment group (P > 0.05). Compared with before treatment in the same group, there was some improvement in tender joint number, swollen joint number, visual analogue scale (VAS) for patients' global assessment, VAS for physicians' global assessment, ESR, CRP, and HAQ between the two groups, showing statistical difference (P < 0.05). Compared with the control group in the same phase, there was no statistical difference in the treatment group (P > 0.05). There was no statistical difference in the occurrence of adverse events between the two groups.

CONCLUSIONSEtanercept plus TWP could achieve equivalent therapeutic effect to that of Etanercept plus MTX. The two regimens could improve clinical signs, symptoms, and QOL related to RA. They were well tolerated in the treatment of elderly patients with active RA.
