ObjectiveThis study focused on the marketed Chinese patent medicines for the treatment of Functional Diarrhea （FDr） in China and their prescription characteristics， in order to provide support for the clinical application and research and development of anti-FDr Chinese patent medicines. MethodsCollect the information of Chinese patent medicines that have been marketed to treat FDr， use Microsoft Excel 2021 software to conduct preliminary data collation and statistical analysis， and use the ancient and modern medical record cloud platform （V2.3.9） to analyze the standardized Chinese patent medicine prescriptions from the aspects of drug nature and taste， medication characteristics and prescription rules. Results147 kinds of FDr Chinese patent medicines were included in this study. There are a total of 40 varieties of FDr Chinese patent medicines suitable for children； The distribution of dosage forms is mainly pills， tablets， and capsules. 110 prescriptions were screened， among which the proportion of Chinese patent medicines for the treatment of spleen deficiency syndrome was the highest； The top three drug use frequency were licorice， Atractylodes macrocephala， and Poria cocos； The medicinal properties are mainly warm and flat， and the medicinal taste is mostly pungent， sweet and bitter， and most of them belong to the two meridians of the spleen and stomach； The association rules analysis obtains 20 strong association pairing sets； Three drug combinations were obtained by cluster analysis. ConclusionFDr Chinese patent medicine shows unique value in clinical application， especially in the field of children. However， there are still problems such as strong professionalism in the indication expression of drug instructions， limited coverage of the medical insurance catalog， and lack of high-level evidence-based medicine and pharmacoeconomic evidence. To this end， in the future， efforts should be made to build a multi-level evidence-based evidence system， improve medication compliance， and deepen research on syndrome-based medication laws， so as to enhance the clinical application value and scientific connotation of FDr Chinese patent medicines.

Objective:To investigate the expression of ras-related C3 botulinum toxin substrate 3 (RAC3) in glioma tissues and its effect on the migration and invasion of glioma cells.Methods:The expression of RAC3 in 57 glioma patients and their adjacent tissues from the First People’s Hospital of Shangqiu was detected by immunohistochemical assay. According to the experimental requirements, brain glioma cells U87MG were divided into experimental group and control group. The experimental group U87MG cells were transfected with RAC3-siRNA plasmid, and the control group U87MG cells were transfected with MOCK-siRNA plasmid. RAC3 mRNA in each group was detected by fluorescence quantitative PCR. The expressions of RAC3 and MMP2 in each group were detected by Western blot. Transwell was used to detect the migration and invasion ability of cells in each group.Results:The positive rate of RAC3 in glioma patients was 89.47% (51/57 cases) , and the expression rate in paracancer tissues was 14.04% (8/57 cases) . The expression rate of RAC3 in glioma tissues was significantly higher than that in paracancer tissues, with statistical significance ( P<0.01) . After siRNA transfection, mRNA expression of RAC3 in experimental group and control group was 1.23±0.20 and 0.43±0.12, and protein expression of RAC3 was 1.19±0.11 and 0.23±0.08, respectively. The expression of MMP2 protein was 1.19±0.11 and 0.23±0.08, respectively. The expression of MMP2 in experimental group was significantly decreased ( P<0.05) . Transwell assay showed that the number of invasive cells in experimental group and control group U87MG cells was (22±5) and (45±8) , and the number of migratory cells was (34±6) and (90±11) , respectively. In experimental group, U87MG cell migration and invasion ability decreased significantly (both P<0.05) . Conclusion:The high expression of RAC3 in glioma tissues may be related to the malignant degree of development, and affect the migration and invasion ability of glioma cells by regulating the expression of MMP2.

Objective To explore the features of activation mapping induced by olfactory stimulation with functional magnetic imaging (fMRI), which will help to reveal the neural mechanism of olfactory dysfunction and contribute to the earlier diagnosis and treatment of neural degenerative disorders.Methods In this prospective study, 21 healthy volunteers were recruited in the Affiliated Hospital of North Sichuan Medical College from March to October 2015.Olfactory function was evaluated by using Visual Analogue Scale (VAS).During the fMRI scanning, all subjects received olfactory stimulation of rose and lavender odor.The brain activation was obtained by using softwares matlab2008a and SPM8.Results All subjects had normal olfactory function evaluated by VAS score (4.86±0.07).The activated brain areas included: bilateral inferior parietal lobule, bilateral inferior frontal gyrus-orbitofrontal gyrus, left insula, bilateral inferior temporal gyrus, left putamen, bilateral hippocampus, bilateral cingulate cortex, bilateral piriform cortex, bilateral amygdale, left lingual gyrus, bilateral cerebellum (t=2.62, P<0.01).Conclusions Olfactory is associated with multiple brain regions.The combination of olfactory event-related design and fMRI, as an objective measurement of olfactory, can be applied to investigate the olfactory cortical brain mapping.

Objective To investigate high risk human papillomavirus(HR-HPV)prevalence among married women in Beijing and to study the high risk flactors.nethods During March 2007 to September 2008.a total of 6185 married women sampled from 137 communities in 12 districts were screened bv HR-HPV DNA test and cytogical test.The interview was carried out with unified questionnaires.The databage was set up and twice entered in EpiDam 3.0.After checked up,the data were analyzed in SPSS 15.0.Results (1) The HR-HPV infection rate was 9.89%.The HR-HPV infection rate of the city zone,the suburb and the exurb were 9.34%,10.51% and 9.51% (P>0.05).The HR-HPV infection rate of the native and the oudander were 9.53%,11.30% (P<0.05).(2) The age distribution of HR-HPV infection was that the rate was around 10% among 25 to 44 age groups,which was the highest(11.21%) in 30 to 34 age group;then the rate was descended as the age raising,the rate of 50 to 54 age group was the lowest(7.78%).(3) Multiple logistic regression showed that the related risk factors of HR-HPV infection mainly included 1000 RMB and above of family income per person per month.possessing more than 1 sexual partner of her husband,outlander and hish levels of education.(4) The prevalence of cervical intraepithelial neoplasia(CIN)in HR-HPV positive group wag significantly higher than that in HR-HPV negative group(29.76% vs 3.32%,P<0.01).Conclusions(1)The HR-HPV infection rate among aged 25 to 54 years was 9.9% and there was no significant difference in area distribution.(2)The hish risk population which should strengthen screening was the married bearing-age women with high level of family income,outlander,high levels of education and her husband possessing more than 1 sexual partner.(3)HR-HPV infection is the main risk factor for CIN and cervical cancer.while does not provide a causal relationship with them.The high risk population should be checked regularly to understand the development of HR-HPV infection and CIN incidence.
