Literatures of study on acupoint functional effect of encephalic region with functional magnetic resonance imaging (fMRI) are collected from the database of China National Knowledge Information (CNKI) and Wan fang database. Analysis and comments are made respectively from the status quo of studies on combination of single acupoint, two acupoints and multiple acupoints under both physiological and pathological conditions. The results show that the corresponding encephalic regions can be specifically activated by acupuncture. And different regions can be activated by different acupoints. However, studies on single acupoint, two acupoints and three acupoints are the major researches carried out at present. It is still lack of observation on effect of commonly-used combinations in clinic. Moreover, the reliability of the research results are also affected by disunity of operations protocol, reinforcing or reducing manipulations, intensity or depth of stimulation and duration of needling retention. Therefore, it is necessary to establish a unified and standard operation protocol to strictly control the bias factors which may affect the result of research in the future, and take patients as the study target as much as possible, so as to further explore the central effect mechanism.

[ABSTRACT]OBJECTIVETo explore the role and mechanism of IL-13 in regulating the differentiation of ciliated cells on cultured human primary nasal epithelial cells.METHODSHuman nasal epithelial cells were cultured in vitro and treated by IL-13, the differentiation of epithelial cells was observed by western blot detection ofβ-tubulinⅣ and ELISA detection of MUC5AC; the percentage of ciliated and goblet cells was quantified by cytospin followed by immunohistochemical staining; the expression level of central ciliary genes was detected by real-time PCR.RESULTSCompared with control group, IL-13 treatment for 14 day significantly decreased the percentage of ciliated cells and expression ofβ-tubulinⅣ, additionally increased the goblet cells and the secretion of MUC5AC; IL-13 treatment significantly reduced the expression of ciliary key transcription factors such as FOXJ1, RFX2 and RFX3, as well as basal body biogenesis genes like CCNO and CETN2.CONCLUSIONIL-13 inhibits the differentiation of human nasal ciliated epithelial cells, which may be by down-regulating the expression of ciliary key transcription factors and basal body biogenesis proteins.

Diagnosis related groups (DRGs)have been widely used in many countries and regions.The versions of DRGs in different regions are modified according to the local circumstances and conditions.Beijing version DRGs (BJ-DRGs)is the first DRGs system in Chinese,which was developed locally based on the conditions of medical information system and health relative policies in Beijing.This paper introduced the grouping principles,logic and methodology of BJ-DRGs.Taking“ear,nose,mouth and throat disorders”for example,this paper demonstrated the grouping process of BJ-DRGs.

Objective To investigate the clinic results of treatment of distal tibiofibular fractures by in- direct reduction and plate fixation through inferior fibula.Methods Between 2002 and 2005,32 cases of distal tibiofibular fractures were treated with indirect reduction and plate fixation through inferior fibula.According to the AO/ASIF classification,there were 17 cases of type A,nine cases of type B,and six cases of type C.Twenty of them also received iliac autograft through a limited median incision at the lower tibia to repair their lateral tibial defects.After operation their ankle joints were fixated at 90?with piaster brace and cast for three months.The bone union,wound and the function of the ankles were observed after surgery.Results All the patients were followed up for an average of 16 months.The average bone union time was 14 weeks.No nonunion,screw loosening,broken plate,or infection of the wounds was found in this series.The excellent and good rate was 84.4% according to Mazur's ankle joint function scoring.Conclusion Indirect reduction and plate fixation through inferior fibula is a satisfactory technique in the treatment of distal tibiofibular fractures.

Objective To investigate the effects of methylprednisolone(MP) on the expression of matrix metalloproteinase(MMP)-9 and airway inflammation in murine models of asthma. Methods Thirty female BALB/c mice were randomly divided into asthma group,MP group and control group(n=10).Murine models of acute asthma were established by ovalbumin(OVA) via peritoneal injection and intranasal instillation.The pathological changes of lung tissues were observed with HE staining,and cell quantitation was conducted in bronchalveolar lavage fluid(BALF).The expression of MMP-9 protein was determined by immunohistochemistry and gelatin zymogram,and the expression of MMP-9 mRNA was detected by RT-PCR. Results Compared with control group,there were more significant airway spasm and more infiltration of inflammatory cells in histologic examination,and there was higher eosinophil cell quantitation in BALF in asthma group(P

To understand the impact of salvianolate injection treatment of liver and kidney function using different from the hospital information system nationwide 18 large three hospitals (hospital information system, HIS) to extract using salvianolate age 18-80 years-old patient, a total of 10 470 cases, depending on the treatment used to have two times before and after treatment 7 d aspartate aminotransferase (AST), alanine aminotransferase patients (ALT), serum creatinine (Cr) and blood urea nitrogen (BUN) measurement indicators grouped according salvianolate continuous use different treatment patients were divided into two groups, continuous medication time > 14 d were defined as the observation group, ≤ 14 d were defined as the control group, continuous medication longer than 31 d were not included in the analysis. Each index number of the observation group and the control group were: ALT (268/1 465), AST (270/1 585), Cr (278/1 582), BUN (278/1 611). After using propensity score methods to balance two groups of covariates, based on unweighted logistic regression logistic regression propensity score weighting combined with propensity score weighting to adjust for covariates logistic regression of liver and kidney function in the two groups were analyzed. The results showed: three logistic regression analysis showed no likelihood of ALT, AST, Cr targets two groups of patients with abnormal statistically significant difference, continuous medication time > 14 d may increase the risk of abnormal BUN indicators, comprehensive analysis still can not explain use different treatment of patients salvianolate cause liver and kidney toxicity damage, still large prospective randomized controlled trials further study.

Background and purpose: Urokinase-type plasminogen activator receptor is related to invasion and metastasis of tumor. Inhibition of uPAR expression in tumor cells results in reducing its metastasis. This study was aimed to construct an expression vector with short hairpin RNA (shRNA) of uPAR, which could pave the way for RNAi-mediated tongue squamous cell carcinoma therapy. Methods: Genome sequences of uPAR gene were retrieved from Genhank and cDNA was designed to code expression of shRNA for uPAR gene. The cDNA was synthesized and inserted into the eukaryotic expression vector pWH1, and the recombinant pWH1-uPAR expression vector was identified by enzyme cutting method. Then, pWH1-uPAR expression vector was transfected into tongue squamous cell carcinoma Ts cells by Lipofectomine 2000. At last, the expression of uPAR in Ts cells transfected with pWH1-uPAR expression vector was observed by RT-PCR, immunocytochemistry staining and Western blot. MTT assay was performed to measure the proliferation of Ts cell. Results: The uPAR shRNA eukaryotic expression vector was successfully constructed. Compared with Ts cells and Ts cells transfected with plasmid pWH1, the Ts cells transfected with pWHI-uPAR expression vector showed a lower mRNA and protein expression of uPAR. The inhibition rate of proliferation was 32.9% of Ts cells by transfected with pWHl- uPAR. Conclusion: The constructed uPAR shR.NA expression vector could inhibit the expression of uPAR in tongue squamous cell carcinoma, which may be helpful for further research on the function of uPAR and provide effective methods for therapy of tongue squamous cell carcinoma.
