Objective: we investigated the biological effects of exogenous S100A6 on osteosarcoma cell line U2OS and explored its possible mechanism. Methods:MTT assay was used to determine S100A6 influence on U2OS cells proliferation and their conce ntration-dependent relationship. The trypan blue exclusion assay was used to observe S100A6 inhibitory effect on U2OS cells proliferation in a time-dependent manner;Hoechst staining was used to determine cell apoptosis;Western blot and immunocytochemical methods to determine expressions of cyto-?-catenin. Results:We found that ,on the first three days,OD values in cells subjected to the recombinant protein S100A6(GST-S100A6)with the concentrations of 30,100,300 and 1 000?g/ml respectively were obviously lower than those in the GST group,by 20.5%,23.7%,32.2% and 36.8% accordingly(P

Objective:To prove the feasibility and validity ofXing Nao Jing acupoint-injection (XNJ-AI) at Fengchi (GB 20) for pseudobulbar palsy caused by ischemic stroke (PBP-IS).
Methods:An assessor-blinded, two-parallel-group, randomized controlled trial was conducted, and the patients with PBP-IS were recruited and randomly divided into two groups. Patients in the control group received oral aspirin (100 mg per day for 2 weeks). In addition to oral aspirin; patients in the treatment group received XNJ-AI at Fengchi (GB 20), once a day, for two weeks. The primary outcome was assessed by the water-swallowing test (WST). Thromboxane B2 (TXB2) and 6-keto-prostaglandin F1a (6-keto-PGF1a) in plasma were measured before and after the treatment.
Results:In the treatment group, the percentage of swallowing function no less than grade 3 before and after the treatment was 32% and 88%, respectively; in the control group, it was 28% and 76% before and after the treatment, respectively; the difference after the treatment between the two groups was statistically significant (P<0.05). There were statistical differences between pre- and post-treatment levels of plasma TXB2and 6-keto-PGF1αin the two groups (bothP<0.05). After the treatment, there were significant differences in the levels of plasma TXB2 and 6-keto-PGF1α between the two groups (bothP<0.05).
Conclusion:XNJ-AI at Fengchi (GB 20) can improve the patients’ swallowing function and balance the levels of TXB2 and 6-keto-PGF1α in plasma.

Objective: This thesis describes a pulse monitoring system based on MCU and GSM. Methods: Monitoring system is a wireless remote monitoring devices which using the SMS in GSM mobile communications network. The signal of pulse is acquisited by Acquisition Circuit, after timing and counting by MCU, pulse rate above the standard is directly transmited to family cell or Dr Mobile by GSM. Results: If the patient arises suddenly heart disease, monitor can be promptly sent to the pulse rate above the standard for family cell or Dr Mobile so that patients receive timely aid. Monitor has advantages of a wide coverage, economic and convenience. Conclusions: The monitor will greatly reduce the burden on the patient's family and hospital, This pulse monitoring system can meet with demands of service in the family and villa nursing and hospital.

Objective To investigate the prevalence of morphological abnormalities of the internal carotid artery and relationship with ischemic cerebrovascular disease and carotid atherosclerosis.Methods A total of 511 consecutive patients were enrolled in this study and carotid abnormalities were classified according to the criteria of Wain and Metz by combining high-and low-frequency ultraaonography prospectively.Relationship of carotid abnormalities to ischemic cerebrovascular disease and carotid atherosclerosis were analyzed.Results Of the 511 cases,abnormalities of the internal carotid artery were found in 256(50.1 ％),the unilateral carotid abnormalities were found in 121(23.7％),and the bilateral in 135(26.4％),respectively.There was significantly difference in prevalence of kinking and coiling between ischemic stroke and asymptomatic group(P＜0.001),and prevalence of carotid abnormalities in the plaques and arteriosclerosis groups were statistically higher than the normal group(P＜0.001).Conclusions The kinking and coiling of the internal carotid artery could be additive risk factors in the pathophysiology of an ischemic stroke,and carotid morphological abnormalities could be responsible for carotid atherosclerosis partly.

Objective To explore the effect of motivational interviewing on the self-care of type 2 diabetic patients . Methods Totally 96 inpatients with type 2 diabetes were randomly divided into the control group and the intervention group , each group containing 48 patients. The control group received routine diabetes education, while the intervention group received face-to-face and one-by-one motivational interviewing intervention for three months. The patients′self-care level were evaluated by using diabetes self-care scale after intervention. Result After intervention, the score on the self-care behaviors including diet control, exercise therapy, medication , blood glucose monitoring and foot care were significantly higher in the intervention group than those in the control group (P < 0.01). Conclusion Motivational interviewing can improve the ability of type 2 diabetic patients to control the glycemic level.

Objective:To explore and optimize the preparation method of specimen about mouse liver tissue for scanning electron microscopy.Methods: The specimens of mouse liver using for scanning electron microscope were prepared through improving the fixed location of perfusion, optimizing material and procedure of perfusion, adopting fixation of perfusion via portal vein and changing the process of fixation and so on. And the results of morphological observation of histocyte were compared between the improved method and traditional method.Results: The improved preparation method could save the liver tissue and the living state of the cells in preferably situation. By using this method, the ultra-micro morphological structure of liver tissue and cell could be clearly observed and the ideal effect of observation could be achieved. Besides, its operation was simple and its success rate was high. Therefore, it was superior to traditional method.Conclusion: The preparation of specimen about the fixation of mouse liver tissue via perfusion of portal vein for scanning electron microscope is a superior method, which has certain applied value.

Objective To investigate the influence of nicotine on the metabolism of dopamine (DA) in the striatum and on the spontaneous locomotor activity of MPTP-induced PD mice. Methods 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced PD model in mice was prepared. The effects of MPTP and nicotine on the levels of dopamine, its metabolites of 3,4-dihydroxyphenlacetic acid (DOPAC) and hemovanillic acid (HVA) were analyzed with high-performance liquid chromatography and electrochemical detection(HPLC-EC); also, tyrosine hydroxylase (TH)-positive nerve fibers were measured by immunohistochemical analysis. Results After injection of Nicotine, the spontaneous locomotor activity of MPTP-treated C57BL mice was significantly lower than that of the control mice, suggesting the nicotine's inhibiting effects ( 44.86?8.51 vs. 57.28?3.27, P

Objective To investigate the degradation rate of profenofos in soil. Methods The residues of profenofos at different times after spraying on soil were determined by GC-FPD method. Results Detection limit of profenofos in soil was 0.04 mg/kg. The recovery rates and relative standard deviation obtained by adding standard assay were 95.2%～98.7% and 3.4%～4.5% respectively. According to the dose recommended, degradation of profenofos sprayed on soil was consistent with one range dynamics. The half-life of profenofos in soil was 1.09 days. At the 13th day after spraying on soil, 98.3% of profenofos had degraded. Conclusion This method was simple, rapid, accurate and precise. The degradation of profenofos was more rapid and profenofos contamination in soil was not a serious problem.
