To analyze the composition and medication regularities of prescriptions treating hypochondriac pain in Chinese journal full-text database (CNKI) based on the traditional Chinese medicine inheritance support system, in order to provide a reference for further research and development for new traditional Chinese medicines treating hypochondriac pain. The traditional Chinese medicine inheritance support platform software V2. 0 was used to build a prescription database of Chinese medicines treating hypochondriac pain. The software integration data mining method was used to distribute prescriptions according to "four odors", "five flavors" and "meridians" in the database and achieve frequency statistics, syndrome distribution, prescription regularity and new prescription analysis. An analysis were made for 192 prescriptions treating hypochondriac pain to determine the frequencies of medicines in prescriptions, commonly used medicine pairs and combinations and summarize 15 new prescriptions. This study indicated that the prescriptions treating hypochondriac pain in Chinese journal full-text database are mostly those for soothing liver-qi stagnation, promoting qi and activating blood, clearing heat and promoting dampness, and invigorating spleen and removing phlem, with a cold property and bitter taste, and reflect the principles of "distinguish deficiency and excess and relieving pain by smoothening meridians" in treating hypochondriac pain.

The paper is to systematically evaluate the effect and safety of Shenqi Fuzheng injection (SFI) combined with first-line chemotherapy for non-small cell lung cancer (NSCLC). Randomized controlled trials (RCTs) on Shenqi Fuzheng injection (SFI) combined with first-line chemotherapy (experiment group) and chemotherapy alone group ( control group) were electronically retrieved from Medline, EMbase, Clinical Trials, Cochrane Library, CBM, CNKI, VIP, and Wanfang Data base. All trials were assessed for quality according to the Cochrane Reviewer's Handbook for Systematic Reviews of Intervention and then Meta-analysis was performed withRevMan5. 2 Software. A total of 43 RCTs (3433 patients) were included after screening and selecting. Results of Meta-analysis showed that: Objective remission rate (ORR): ORR of experimental group was about 20% higher than that of control group [RR = 1.23, 95% CI (1.11,1.35), P < 0.0001]. Disease control rate (DCR):DCR of SFI combined with first-line chemotherapy was 11% higher than that of first-line chemotherapy alone [RR = 1.11, 95% CI (1.07, 1.16), P < 0.000 01]. Life quality evaluated by Kosovan performance status (KPS) showed that: life quality improvement rate of experimental group was about twice of that in control group [RR = 2.02, 95% CI (1.81, 2.26), P < 0.000 01]. Toxic and side reaction analysis showed that: the incidence of side reactions in experimental group was about 50% lower than that in control group [RR = 0.59, 95% CI (0.53, 0.66), P < 0.000 01]. Immune function test showed that: the function of experimental group was 3.2 (standard deviations) times greater than that of control group [MD = 3.23, 95% CI (2.86, 3.60), P < 0.000 01]. We can see that SFI combined with first-line chemotherapy for NSCLC can increase objective efficacy, improve life quality, decrease toxic and side reactionsinduced by chemotherapy, and improve the immune functions. As most of the included studies in this systematic evaluation had poor quality, the evidence to support conclusion was weak, so it was necessary to conduct more multi-center clinical trials with high quality methods and rigorous design.

Objective To introduce the clinical apply of middle and small skin defect in finger injury with lateral arm free perforator flap.Methods (1) Ten cadavers were injected with a modified lead oxide-gelatin mixture.Later,CT scan,three-dimensional reconstruction of the cutaneous perforator vessels on the later arm.Then simulate the flap design.All cadavers were dissected before CT scanning.(2) Eighteen cases of middle and small skin defects in finger injury were treated with lateral arm free flap.The defect area were from 3 cm × 4 cm to 6 cm × 9 cm.Results Our research showed that the average caliber diameter of perforators of profunda brachial artery(PBA) was (0.71 ± 0.15) mm,and Posterior radial collateral artery(PRCA) was (0.94±0.22)mm.The results of pedicle length of perforator of PBA was (2.74 ±0.42) cm:(2.96 ±0.37) cm,and PRCA was (4.78 ±0.63) cm:(4.86 ±0.51) cm.3D reconstructive results showed that the perforators of PBA and PRCA dominated the lateral upper arm area.The flap of 18 cases survived after the operation.The wound of providing area was directly sutured or skin grafting and got healing.All cases were followed up for 6 months to 3 years,and the average follow-up time was 11 months.There was a little swelling on the outlooks of the flap,but the texture and sensation of the flap was good.Conclusion The lateral arm free perforator flap has a stable vessel pedicle,good texture and sensation,so it was a good method to repair middle and small skin defect in finger injury.

Objective　To study the effects of prolactin on interactions between Graves′ disease (GD) thyrocytes and autologous peripheral blood mononuclear cells (PBMC) in coculture. Methods　Primary thyrocytes and autologous PBMC were cocultured at various levels of ovine prolactin (oPRL) in vitro. The activation and proliferation of PBMC as well as HLA-DR and CD40 expressions on thyrocytes were determined by immunofluorescent staining and flow cytometry. Results　 With PBMC in GD cocultures, oPRL caused significant increase in the percentage of CD4+CD25+ cells at 200 μg/L ［(13.08±2.54)%, P＜0.01］ and in the proliferative index at 200 μg/L ［(17.82±3.02)%, P＜0.01］ and 1 000 μg/L ［(16.57±2.56)%, P＜0.05］, but not at 12.5 μg/L ［(10.43±2.38)% and (14.08±2.67)%, respectively］ or 50 μg/L ［(9.94±2.54)% and (14.56±2.80)%, respectively)］. The values at 200 or 1 000 μg/L as above were also significantly different from those at 12.5 or 50 μg/L. The percentage of CD40+ cells ［(48.25± 6.63)%，(52.28±6.94)%］ and delta mean fluorescence intensity (dMF; 42.94±10.24，49.51±12.34) were significantly lower in thyrocytes in GD cocultures treated with 200 or 1 000 μg/L oPRL than those untreated ［(58.38±6.62)% and 67.30±20.20］ or treated with two other concentrations of oPRL. The percentage of HLA-DR+ cells ［(46.79±7.51)%, P＜0.01］ and dMF (21.02±5.43, P＜0.01) were significantly higher in the thyrocytes treated with 50 μg/L oPRL than those untreated ［(33.51±8.58)% and 13.91±3.88］ or treated with three other concentrations. There were no significant differences between the dose groups of oPRL but those mentioned above. Conclusions　Prolactin could affect interactions between GD PBMC and autologous thyrocytes and might eventually influence the shift of helper T cells. High prolactin levels might aggravate GD.

Radiotherapy is the primary treatment for nasopharyngeal carcinoma, and the disease control rate and survival time are able to be greatly improved by enhancing the radiosensitivity. Via mechanisms such as binding to target genes mRNA 3'untranslated region (3'UTR), microRNA (miRNA) inhibits translation, which therefore regulates transcription of target genes and thus affect target protein expression. Recent research showed that miRNAs play significant roles in improvement of radiosensitivity in nasopharyngeal carcinoma. This article reviews mechanism of miRNA action to strengthen radiosensitivity of nasopharyngeal carcinoma and the future of clinical practice of miRNA in this disease.

Objective To investigate the drinking water quality of secondary water supply in Tongzhou District, Beijing in order to establish a data monitoring management system. Methods The uniform questionnaires were used for the on-the-spot investigation at secondary water supply units in the whole district, which included secondary water supply facility situations, environmental sanitary conditions and health management and so on. At the same time, municipal water and secondary supply water were tested. Results 48 units of secondary water supply were investigated. In this investigation, the main systems of secondary water supply were the low water tank added frequency conversion pump(accounts for 77.1%) and the inverter constant pressure water supply system with negative pressure(accounts for 14.3%). According to the hygienic requirements, the unqualified rate of water tank structure, disinfection facility and water tank room were 81.0%, 73.3% and 87.3% respectively; besides, 39.6% of the units used the invalid hygienic licenses, 43.5% of the water managers had no health certificates, and 54.5% of the units had never cleaned their water tanks. The total qualification rate of the secondary water supply was 66.7%. The main items that were not up to the standard were ammonia-nitrogen, free chlorine, recognizable objects with naked eyes, total bacteria count and turbidity. For the different water material, the qualification rate showed a significant difference(P=0.023). Conclusion The drinking water quality of the secondary water supply is lower than before and the preventive hygiene supervision and evaluation is comparatively delayed in the investigated district.

Abstract Objective:To investigate whether mRNA of prolactin(PRL) ,an important immunomodulatory hormone,is expressed in thyroidglands of patients with Graves'disease(GD) .Methods:The expression of PRL mRNA was examined by nonisotopic in situ hybridization in GDthyroid glands and the control ones( including multinodular goiters and samples of normal thyroid tissue adjacent to adenomas) as well as intra-thyroidal mononuclear cells isolated from GD thyroid glands and primary thyroid follicular cell(TFC) cultures derived from them.Results:PRL mRNA was expressed in GD thyroid glands, but not in the control ones. It was localized in infiltrating mononuclear cells and vascular endothelial cells adjacent to mononuclear cell infiltrates, but not in TFC .(9.8?.3)% (x ?s) of intrathyroidal mononuclear cells isolated from GD thy-roid were found containing PRL mRNA.It was absent in the primary TFC cultures. Conclusion:PRL mRNA is expressed in GD thyroid tissue. This indicates that PRL-like substance can be locally produced in GD thyroid tissue, which may play an important role in GD pathogenesis by autocrine and paracrine mechanisms.
