Chinese Journal of Schistosomiasis Control 1989;0(02):-
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 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.

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

This paper deals with the analysis of the phospholipids and fatty acids in Hippocomnpus kelloggi Jordan et Synder, H. Histrix Kaup, II. trimaculalus Leach, II. kuda Bleeder, II. japonicus Kaup, Solenognathus hardwickii(Gray), Syngnathoides biacufcatus(Bloch) and Tracliyrliamphus serralus (Temminck &. Schlegel).The total phospholipids were extracted with Folch solvent and determined by molybdate blue spec-trophotometric method. The result showed that the contents of total phospholipids in these spccimins were 2. 56-7. 82mg/g.The nine kinds of phospholipid standards of absorbance proportional coefficient were detected in this paper. The phospholipid components were separated and determined by using thin - layer chro-matographic method and Vaskovsky solvent as a specific spray reagent. The quantitative analysis of the distribution of various phospholipids components in these specimen ts were carried out, by using TLC scanning and the corrective method of absorbance proportional coefficient. The resut showed that the Hippocampus contains about five phospholipids: lysophosphatidylcholine, sphingornyelin, phophatidylcholine, phosphatidylinositol, and phosphatidylethanolamine. The phosphatidylserine , phosphatidylglycerol, diphosphatidylglycerol and phosphatidic acid were more in Syugnathus than in Hippocampus, But in all these specimens, the main phospholipid components were lysophos- phatidylcholine, sphingornyelin and phosphatidylcholine.Fourteen fatty acid compositions in these specimens were analysed by GC -MS -DS. The result showed that the main fatty acid were hexadecanoic acid, 9 - octadecenoic acid, 8,11- octadeca-dienoic acid and 1,7,10,13,16,19 - docosahexaenoic acid.

Objective The Application of Circular Mapping during Circumferential Pulmonary Vein Ablation (CPVA) for Atrial Fibrillation Guided by Ensite/NavX System. Methods To evaluate the effect of combined circular mapping on the success rate of CPVA. 61 consecutive cases (40 males and 21 females) were included in the study. 50 cases with paroxysmal atrial fibrillation (PAF) and 11 cases with chronic atrial fibrillation (CAF) underwent CPVA guided by the Ensite/NavX system. A circular electrode catheter was used to map the pulmonary vein (PV) potentials. Pulmonary vein isolation was taken as the endpoint for ablation. Results All the 61 cases underwent the procedure successfully. LPVs were isolated in 34 cases and 35 cases underwent single RPVs isolation. Circumferential ablation of both LPVs and RPVs were carried out in 23 cases. Atrial fibrillation was terminated when delivering radiofrequency energy in 16 cases with PAF and 5 cases with CAF. The termination sites were located near the anterior or posterior roof of the superior PVs in 19 cases and at the mid-portion of the posterior wall from RSPV in 1 case. Atrial fibrillation was terminated when after comple to LPV ablation in 1 case. During the follow-up of 6?2 months, 42 PAF cases and 5 of 11 CAF cases were atrial fibrillation free. The total success rate was 77%. Complications: Pericardium effusion was found in 1 case and disappeared after pericardium puncture and drainage. 1 case developed hemothorax and was cured after thorax puncture and drainage. Conclusion The application of circular mapping during circumferential pulmonary vein ablation guided by Ensite/NavX System contributes to improve the success rate of atrial fibrillation ablation.
