Objective:To investigate the role of TACE in the mechanism of sciatica due to disc herniation.Methods:Autologous nucleus pulposus was applied to the peripheral of the L4 and L5 nerve roots and DRGs to construst animal model.Then Von Frey filaments and a thermal testing device(RTX-1 type)were used to quantify behavior test.Immunocytochemistry and RT-PCR were used to detect the ex-pression changes of TNF-?and TACE to analyze their correlation with the nerve behavior change.Results:The mRNA expression of TNF-?and TACE increased significantly(P

The ideas for constructing information purchase platform for scientific research materials were put forward and the targets for its step-by step implementation were worked out according to the analysis of problems existed in purchasing scientific research materials with chemical agents as an example.The construction of information pur-chase platform for scientific research materials plays an important role in enhancing the cost-effectiveness of outlay for scientific research, assuring the safety of founds for scientific research, and improving the service of purchase administrative offices.

To investigate the effect of proteasome inhibitor MG132 on the apoptosis of bovine lens epithelial cells (BLECs), the cells were treated with MG132 at different concentrations for12, 24 and 36 h. The cell viability was analyzed by MTT assay and the effect of MG132 on the apoptosis of BLECs was assessed by flow cytometry (FCM). The results showed that after treatment for the same period, the inhibitory effect of MG132 on BLECs proliferation was enhanced with the increment of the concentration of MG132 (0, 2, 5, 10, mumol/L) (P<0.05). The 50% inhibiting concentration (IC(50)) was 2.03 mumol/L when the BLECs were treated with MG132 for 36 h. MG132 also induced the apoptosis of BLECs obviously. FCM showed that the apoptosis index of the cells treated by MG132 at 2 mumol/L for 12 h was (20.24+/-1.51)%, and that of the control was (0.98+/-0.20)% respectively (P<0.01, n=3). It was concluded that MG132 could lead to apoptosis of BLECs. The decrease of proteasome activity may play an important role in the formation and development of cataract.

Objective To establish a capillary gas chromatography method for the determination of menthol and methyl salicylate in Shangtongning adhesive plaster. Methods The internal standard substance of n-Pentadecane was employed. The GC system consisted of a DB-WAX capillary column (30 m?0.32 mm, 0.25 ?m), nitrogen as the carrier gas, column temperature at 130 ℃, FID as the detector at 200 ℃, and with a split ratio of 12∶1. Results The contents of menthol and methyl salicylate in 6 lots of samples were determined and the constituents concerned were separated well under the chromatographic condition. The average recovery of menthol and methyl salicylate were 101.52% (RSD=2.66%) and 100.34% (RSD=3.38%), respectively. Conclusion The method was sensitive, accurate, specific and suitable for the quality control of the preparation.

By direct communication between clinicians and laboratorians, obstacles between clinical work and laboratory diagnosis were unequivocally found at an academic conference. Many clinical physicians feel disappointed and frustrated at the laboratory diagnosis by semen analysis and frankly express their expectations, as to recognize the role and significance of laboratory diagnosis, understand the value of routine semen analysis, work out the puzzles in the analysis of sperm morphology, fulfil the requirements for the identification of cells in semen, and obtain responses from and initiate discussions among laboratorians about the relevant questions. Both laboratorians and clinicians are appealing for strengthened management and earlier establishment of national standards and operating specifications for laboratory diagnosis by semen analysis.

Objective To investigate the effects of mindfulness training on cancer related fatigue (CRF) in patients with breast cancer .Methods Two hundreds young and middle‐aged patients with breast cancer receiving chemotherapy in our hospital from January to June 2015 were divided into the observation group and control group ,100 cases in each group .The control group was given the routine nursing ,while on this basis the observation group was given the mindfulness training .The cancer related fa‐tigue status was evaluated according to the CFS scale .The CFS various dimensions and total fatigue scores before and after inter‐vention were compared between the two groups .Results The fatigue status existed in most of patients with breast cancer after chemotherapy ,the occurrence rate of CRF was 97 .0% ,which was dominated by moderate fatigue ,followed by mild fatigue ,severe fatigue was minimal ;the body fatigue ,cognitive fatigue ,emotional fatigue and total fatigue scores in the second time of chemothera‐py had no statistically significant differences between the two groups (P>0 .05);in the fourth and sixth time of chemotherapy ,the body fatigue ,cognitive fatigue ,emotional fatigue and total fatigue scores in the observation group were significantly lower than those in the control group ,the differences were statistically significant (P<0 .05) .Conclusion The mindfulness training interven‐tion can relieve the fatigue status and improve the living quality of the patient .

0.05). Conclusions:Compared with normal esophageal mucosa, the expression of HSP27 mRNA in esophageal squamous carcinoma and mucosa with atypical hyperplasia was markedly decreased.This indicated that the expression of HSP27 mRNA to a greater or less extent lost in the carcinogenesis and development of esophageal squamous carcinoma. To up-regulate the expression of HSP27 mRNA in esophageal squamous carcinoma may be a very effective biological therapy.

Visual analogue scales(VAS) is extensively applied on evaluating symptomatic outcome data,such as the pain intensity,but currently most of the management of relevant data can't conform to the statistical standard.This article categories the data measured with VAS and the eligible statistical methods,give a specific explanation about analysis of repeated measures data which may commonly misused in practice.It provides a reference criterion for statistical analysis with VAS in clinical research.
