Objective:To observe the effects of Naoxuekang oral liquid combined with nimodipine on hypertensive cerebral hemorrhage and the influence on serum Tau protein,IGF-1 and hs-CRP in the patients. Methods:Totally 98 patients with hypertensive cerebral hemorrhage were randomly divided into two groups(n = 49). The patients in the control group were given nimodipine,while those in the observation group were given nimodipine and Naoxuekang oral liquid at the same time,and all the patients received 4-week treatment. The serum levels of Tau protein,IGF-1 and hs-CRP before and after the treatment were detected,and the national institutes of health stroke scale(NIHSS)score,hematoma volume and curative effect and adverse drug reaction were recorded as well. Results:Before the treatment,there was no significant differences in Tau protein,hs-CRP, IGF-1,NIHSS score and hematoma volume between the two groups(P > 0. 05). After the treatment,the levels of Tau protein and hs-CRP,NIHSS score and hematoma volume in both groups were decreased,and those in the observation group were lower than those in the control group;the IGF-1 level in both groups was increased,and that in the observation group was higher than that in the control group;and all the differences had statistical significance(P < 0. 05). There was no significant difference in the complication rate between the groups( P > 0. 05),while the effective rate of the observation group was significantly higher than that of the control group(89. 8% vs 73. 5% ,P < 0. 05). Conclusion:Naoxuekang oral liquid combined with nimodipine can significantly reduce the serum levels of Tau protein and hs-CRP,and increase the serum level of IGF-1,and improve the symptoms of patients with hypertensive cerebral hemorrhage,which is beneficial to the rehabilitation of patients.

Objective:To observe the expression of connective tissue growth factor(CTGF) and its receptor-low density lipoprotein receptor-related protein (LRP), and the relevant signaling pathway for the regulation by long-term high glucose exposure in cultured podocytes. Methods:The effects of high glucose on the expression of CTGF and its receptor LRP were analyzed by western blotting. The activation of mitogen activated protein kinase ( MAPKS )signaling pathway by high glucose was also examined. Results: Basal levels of CTGF were observed in cultured mouse podocytes, the levels of CTGF protein were increased by high glucose medium groups on the 2nd day, reached the peak on the 4th day(P0.05).The levels of CTGF expression in normal glucose and mannitol glucose groups did not change markly. High glucose medium induced phosphorylation of ERK_ 1/2 at as early as minute 30, reached the peak at hour 6; maintained the activity at hours 12 and 24, and declined to the basal level at hour 48. However, phosphorylation of ERK_ 1/2 was not detected in normal glucose and mannitol glucose groups. Blockade of phosphorylation of ERK_ 1/2 with PD98059, a specific ERK_ 1/2 activation inhibitior, did decrease the high glucose-triggered expression of CTGF protein in 4 days. High glucose had no effect on the expression of LRP protein at each time point. Conclusion: Acute high glucose (2-4 days)stimulated the expression of CTGF protein via ERK_ 1/2-dependent signaling pathway in cultured podocytes, while cultured in high glucose for 6-8 days, the podocytes did not increase its CTGF level. Long-term high glucose had no effect on the expression of LRP in podocytes.

Objective To study the influence of various doses and injection rates of contrast agent on CT perfusion in rabbits' liver with a deconvolution mathematical model. Methods Eight rabbits were enrolled in the experiment. Randomized block design was adopted. The treatment factor (contrast medium injection rate) was classified into 0.5, 1.0, 1.5 ml/s, while the subjects were divided into 3 blocks with contrast medium injection dose of 0.5, 1.0 and 1.5 ml/kg. The data obtained at CT perfusion imaging were then transferred to the workstation. Absolute values of 7 perfusion parameters (hepatic arterior fraction, blood flow, blood volume, permeability surface, mean transmit time, hepatic artery perfusion and portal vein perfusion) were measured with perfusion software (Perfusion 3). Results The dose of contrast medium had significant effect on peak enhancement of the aorta, the portal vein and liver tissue (P<0.05), whereas the injection rates had significant influence on the arrival time to peak enhancement of the aorta and the portal vein. However, the dose of contrast medium and injection rates had no significant effect on perfusion parameters (P>0.05). Conclusion CT perfusion imaging with a deconvolution mathematical model can quantify the hemodynamic functional status in liver with stable results. This technique does not need strict confinement to dose and injection rate of contrast medium, and has great potential value to be put into clinical use.

Objective To explore the clinical significance of lymph node micrometastases in stage Ⅱ rectal cancer patients. Methods Forty-two patients with rectal cancer underwent total mesorectal exci-sion between January 2000 and August 2001 were included, 484 lymph nodes were studied in paraffin blocks that had previously been considered free by conventional histopathological examination. These lymph nodes were submitted to immunohistochemical analysis using cytokeratin 20 (CK20) monoclonal antibodies to identify micrometastases. Five-year follow-up information was obtained on these patients. Observed survival rates and assessed respectively in the patients with and without micrometastases. Results Micrometastases were detected in 33 lymph nodes (6.8% ,33/484) of 15 cases (35.7%, 15/42). The five-year survival rate was 40.0% in the patients with micrometastases, whereas in the patients without micrometastases, the survival rate was 92.6%(P = 0.000,by the Log-rank test). By multivariate Cox regression analysis, lymph node mi-cromctastases was closely correlated with post-operative recurrence or metastases, the value of RR was 11.435. Conclusions Detection of micrometastases is an important prognostic tool in stage Ⅱ rectal can-cer. In this study, lymph nodes micrometastases is an independent prognostic factor for overall survival. These patients maybe get benefit from adjuvant chemotherapy.

Objective To block the bio function of TGF ? by the application of anti TGF ? polyclonal antibody, and observe its efficacy of prevention of abdominal adhesion. Methods The postoperative abdominal adhesion model was established in SD rats. The drugs were administrated by abdominal injection with saline (control group), sodium hyaluronate( HA group), and varied dosage of anti TGF? (anti TGF? groups) respectively. The adhesion was scored 21days later, while 30 of them were executed on the day 3 and day 10 after operation respectively. The expression of TGF ? was checked by immunohistochemistry in the samples obtained from the adhesion sites. Results The score of adhesion in anti TGF ? group (2.4?0.99) was significantly lower than that in control group (6.0?1.25) and HA group (3.4?1.03); in different dosage of anti TGF, the 50?g group showed its economical efficacy; in the control and HA groups the expression of TGF ? had a time dependent manner, which reachs to maximum in the day 3, and could be reduced by antibody. Conclusions The polyclonal antibody of TGF ? shows the power to prevent the postoperative abdominal adhesion in animal model, the mechanism of which is due to inhibition of TGF ? expression.

Objective: In this study, a meta analysis was conducted to evaluate and compare the effects of different types of interval training, such as, repeated sprint training(RST), high intensity interval training(HIIT) and sprint interval training(SIT) on body index of overweight/obese college students and the effect of moderate intensity continuous training(MICT), so as to provide a reference for taking appropriate exercise measures. Methods: The data was searched and selected from the database of Web of Science, PubMed, Scopus, The Cochrane Library and CNKI, and from the articles about random research on the effects of HIIT, SIT, RST, and MICT on overweight/obese college students for the evaluation of bias risk. And Stata 16.0 software was used for Meta analysis and network analysis. Results: Totally 815 samples selected from 18 articles were included in the study. Meta analysis showed that HIIT( SMD=-0.26, 95%CI =-0.52--0.00, P <0.05) and SIT( SMD=-0.39, 95%CI =-0.72--0.07, P <0.05) could make greater effects on BMI than MICT. The differences between RST and MICT were of no statistical significance( SMD=0.28, 95%CI =0.32-0.87, P >0.05). According to the SUCRA method combined with effect size, the best effect on improving MetS related physiological indexes of overweight college students was found in SIT( SUCRA =79.3), followed by HIIT( SUCRA =78.2), RST( SUCRA =56.8), and MICT( SUCRA =35.7). Conclusion Compared with MICT, high intensity interval training can greatly improve BMI of the obese/overweight college students, and could achieve the optimal effect of reducing the fat by exercising through SIT.

Objective: To compare the effectiveness of three forms of health education including classroom teaching, network teaching and after class tutoring on exercise behavior among college students. Methods: A literature search was performed using web of science, PubMed, ScienceDirect, Scopus, Cochrane Library, and CNKI database on randomized controlled trials of health education intervention on exercise behavior among college students. Literature filtering, data extraction, and assessment of the risks of bias were conducted by two independent researchers using Stata 16.0 software based on traditional Meta analysis and network meta analysis. Results: A total of 23 literatures were included. The results showed that health education courses could effectively increase the weekly exercise time of college students( SMD =0.29), exercise frequency ( SMD =0.25) and number of students participating in exercise( OR =1.33). Subgroup analysis revealed that the increase in classroom teaching and network teaching associated with increased weekly exercise time ( SMD =0.45, 0.36), exercise frequency ( SMD =0.22, 0.37) and exercise number ( OR =1.36, 1.26)(all P <0.05); The effect of after class tutoring on the time and frequency of weekly exercise was not statistically significant( P >0.05). Indirect comparison showed that the effects of classroom teaching and network teaching on weekly exercise time, and exercise frequency were superior to that of extracurricular counselling( P <0.05); There were no significant differences in the weekly exercise time, frequency and number of participants between the two groups( P >0.05). Based on SUCRA method and the effect size, health education in the form of classroom teaching may have the greatest effect on the weekly exercise time, frequency and the number of students participating in the exercise( SUCRA =91.5, 94.1, 87.1). Conclusion Health education in the form of classroom teaching and network teaching can positively influence exercise behavior of college students.It is suggested that health education courses should be carried out in college courses so as to better promote college students to participate in physical exercise.
