Objective To explore the factors of medical anthropology related to malaria control among Wa Ethnic minority in Ximeng County, Yunnan Province. Methods The study was conducted by the combination of anthropology and epidemiology, qualitative and quantitative, statistical analysis and description. Results Wa people considered malaria as one of three major diseases in the community. In Wa Ethnical language, the word of malaria, “Saihui” (Sai-illness and pain, Hui-being attacked quickly), does not mean of fever. About one third of Wa people had not thought fever as one of malaria symptoms. Most of Wa people only knew vivax malaria, but not falciparum malaria. Only 32.7% of people could connect malaria with mosquitoes, and a few of them could confirm mosquitoes as the only malaria vector. The proportions of sound knowledge of malaria causes, prevention and treatment seeking assessed were lower than 25.0%. As a result of multivariate logistic regression, 3 kinds of malaria knowledge were closely correlated each other, and the connection between causal knowledge and prevention (adjusted OR: 36.610, 95%CI: 10.242-130.866, P

Drug pair is the basic unit of compatibility of formulas.Through selecting the prescriptions of treating diseases of the liver in "Treatise on Cold Pathogenic Diseases" and "Synopsis of Golden Chamber",we,according to therapeutic methods,classify the commonly used drug pairs in treatment of hepatic disease of ZHANG Zhong-jing into eight kinds:regulating the flow of liver-qi,promoting blood circulation by removing blood stasis,dispersing pathogenic wind and calming liver wind,removing jaundice,clearing away liver-heat,expelling liver-cold and warming the liver,nourishing the liver,and harmonizing liver-spleen.And we try to find the compatibility law.

[Objective]To sum up pro. Lian Jianwei’s clinical experience in treating acne. [Method] By proved recipe analysis, it shows pro. Lian Jianwei ’s treatment based on differentiation of signs from different angles and the clinical thought of flexibly applying ancient formulae on acne. [Result] Pro. Lian Jianwei is good at revising ancient formulae for treating acne with good effect, according to patients ’pulse signs and mechanism;if the food is stagnated in the gastric-intestine, which wil transform into heat and up along the channel, Baohe Pil shal be used to remove stagnation and heat; if the liver is de-pressed with heat, deficient blood and weak spleen, Xiaoyan Powder shal be used for regulation and stretching the wood; use Wenqing Drink to nourish blood and remove toxin for deficient blood and hot liver, toxic heat implicated in spleen and stomach; apply Zisheng Pil to regulate and tonify middle part of the body for deficient spleen and stomach with turbidness and dyspepsia, etc. [Conclusion] Pro. Lian Jianwei has rich clinical experience, his clinical thought of “treatment based on differentiation of signs, with flexible methods and formulae, coping with shifting diseases by sticking to a fundamental principle”, worthy our deep experiencing and study.

Objective To assess the effectiveness of prenatal screening with maternal serum markers and the sonographic characteristics of the foetus for detecting trisomy 18. Methods Amniotic fluid or the fetal blood samples were obtained and cultured in women with positive results in serum screening (n=36) and with abnormal findings in sonography (n=92) at 18~32 weeks of gestation, and then fetal karyotyping was performed. Results Nine cases of trisomy 18 and 2 cases of other abnormal karyotype were found among the 128 pregnant women (8.59%, 11/128). Four cases were diagnosed as trisomy 18 among the 36 women with positive screening results. The rate of abnormal karyotype among those women with abnormal sonographic findings was 7.61%(7/92,5 cases of trisomy 18 and 2 cases of other abnormal karyotype). Two cases of trisomy 18 had both positive result in screening and abnormality in sonography. Conclusions Prenatal screening for maternal serum markers combined with sonographic examinations for the fetus is effective in detecting foetus with trisomy 18.

AIM:Many studies have documented an anabolic effect of hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase inhibitors, statins, on undisturbed bone. Reports of their effects on fractured skeleton were limited. A study was therefore conducted to check the effects of statins on fracture healing. METHODS: Simvastatin (10 mg?kg-1?d-1) was injected subcutaneously to tissue overlying the site of fractured tibiae of ovariectomized rats for a treatment period of 5 d. Vehicle reagent was used as control. Healing quality was evaluated at 1, 2 and 4 weeks after fracture. RESULTS: Compared with vehicle group, callus cross section area in simvastatin treated rats were significantly enlarged by 21.3% (P

A method for the infrared spectrophotometric determination of total ph-ospholipids in seed of Juglans regia and acinus of Citrullus vulgaris was reported. The average recovery of total phospholipid in this test was 97.2%, the CV was 1.66%. The contents of total phospholipid in seed of Juglans regia and acinus of Citrullus vulgaris were 438.46-528.85mg% and 241.78 -247.47mg% respectively. The rapid quantitative analysis of the distribution of various phospholipid components in these two specimens was carried out by using thin layer chromatographic scanning and the corrective method of absorbance proportional coefficient. The results showed that the main phospholipid components in both specimens were PC and PE. The fatty acid composition of the total phospholipids of both specimens were analysed by GC-MS-DS (gas chromatography-mass spectrometry-data system).

Objectives To learn the bednet use and influential factors among Wa and Lahu ethnics,and further to explore feasible ways of promoting the use of bednets and insecticide-treated nets (ITNs). Methods Questionnaire surveys and statistical analysis with EpiInfo 2000 software package were carried out. Results Only did 2.8% [95% confidence intervals(95%CI):1.2%-5.4%] of Wa and 4.8 % (95%CI:2.8%-8.1%) of Lahu ethnic members use bednets frequently or sometimes. Bednets were not available for 67.7% (95% CI:62.0%-73.1%) of Wa and 59.7% (95% CI:53.1%- 66.1%) of Lahu ethnic peoples. Most people who had bednets did not often use them for anti-mosquitoes. Results of multivariate logistic regression confirmed significant correlation between bednet use and knowledge of malaria prevention. Conclusion The coverage and use rates are very low in the two ethnical minorities. Health education, communication and social marketing are the strategies for promoting the usage of bednet and ITNs.

Drug resistance is major obstacles in the successful treatment of malignant solid tumors. Multiple mechanisms involeve in development of cancer drug resistance. Recent research suggests dysregulation of microRNAs is associated with cancer drug resistance. The profiles of microRNAs in drug resistance cancer cells or tissues are different with sensitivity cells or tissues in various solid tumors. Restoring microRNAs could improve chemosensitivity of cancer cells. MicroRNAs expression profiles may provide a critical link for understanding mechanisms involved in chemoresistance. We can also find a specific marker for screening chemosensitivity patients through identification of the microRNAs patterns of drug resistance cells or tissues.

Objective To explore the expression and significance of MTSS1 ( metastasis suppressor 1) in hepatocellular carcinoma.Methods MTSS1 expression was detected by immunohistochemistry in hepatocellular carcinoma, liver cirrhosis and normal liver tissues.Single-factor analysis was used to study the relationship with clinicopathological factor.Correlations between MTSS1 expression and TNM stage were analyzed with Spearman rank correlation analysis.Postoperative 5-year survival was evaluated using Kaplan-Meier survival curve analysis.Results The expression of MTSS1 in hepatocellular carcinoma was higher than normal liver tissue ( U = 168.000, P ＜ 0.05), and liver cirrhotic tissue ( U = 106.000, P ＜ 0.05); MTSS1 expression was correlated with TNM stage of hepatocellular carcinoma patients, lymph vascular invasion and tumor capsule ( separately U = 259.000, 258.500, 202.000, all P ＜ 0.05).MTSS1 expression in hepatocellular carcinoma was not correlated with patients age, gender, tumor size, AFP level, and hepatitis B surface antigen.MTSS1 expression and TNM stage of liver cancer patients was negatively correlated ( rs = - 0.383 , P ＜ 0.05 ).Postoperative 5-year survival of hepatocellular carcinoma patients with MTSS1 positive expression was significantly poorer than patients with negative and weakly positive expression (respectively 34.1% and 52.3% , x2 =6.386, P ＜ 0.05).Conclusions MTSS1 high expression may play an important role in the early hepatocellular carcinoma progression, indicating a poor prognosis.
