Objective To analyze the clinical characteristics and risk factors of type 2 diabetes with cerebral infarction in senile patients. Method 52 patients with type2 diabetes and cerebral infarction(group A), 62 cases with-out diabetes mellitus(group B)were enrolled in this study. Waist circle(Wc), body mass index(BMI), blood pressure, blood fat,blood glucose(BG), glycosylated hemoglobin(HbA1C), fasting insulin,leptin and adiponectin were determined in each group. Results Recurrent, multi - focal and large-area infarcts were more common in group A than in group B, and levels of systolic blood pressure (SBP), DBP, PBG, FINS, TG, LDL-C and apoB100 were increased, while levels of adi-ponectin were decreased and high density lipopretein(HDL) and apolipoproteinA1 (apoA1) were increased in group A (P<0. 05). Conclusion Recurrent, multi-focal and huge area infarcts are more common in group A. Cerebral infarc-tion patients with diabetes mellitus than non-diabetic group with a high mortality rate,characterized by high disability.

Zebrafish is a relatively new and booming vertebrate animal model.Over the past three decades, ze-brafish has been applied in various aspects of life science, as well as health sciences, environmental studies and aquacul-ture research.To meet the requirement for different research purposes, large amounts of zebrafish resources, including mu-tant and transgenic lines, have been developed with different techniques.All of these resources need well and careful col-lection and maintenance, therefore several zebrafish resource facilities have been built worldwide.As one of them, the Chi-na Zebrafish Resource Center (CZRC, http://zfish.cn) was founded in 2012.This review is trying to introduce the devel-opment and maintenance of zebrafish scientific resources, and the updated progress of CZRC.

On the basis of outpatients' medical records concerning primary liver cancer (PLC), data of 552 patients (with 2020 effective prescriptions) from the Outpatient Department of Changhai Hospital treated by Professor Ling Changquan were collected. The nature, flavor and meridian distribution of the herbs used in the prescriptions were summarized by frequency method, and the features of the herbs used according to syndrome differentiation were analyzed by logistic regression. The couple herbs used were analyzed by cluster analysis. All the data were analyzed in combination with the experience of the specialist. It showed that most of the frequently used herbs were herbs for invigorating the spleen to promote appetite, removing toxic materials to inhibit tumor growth, and activating blood circulation to dissipate blood stasis. These herbs are mostly of plain or cool nature, and mainly of sweet, bitter, or acrid taste. It also showed that the most frequently used herbs for qi deficiency were Astragalus membranaceus, Atractylodes macrocephala, and Pseudostellariae; Caulis Spatholobi and Chinese jujube for blood asthenia; Fructus Corni and Ophiopogon japonicus for yin deficiency; Agastache rugosa, Semen Plantaginis and Poria for water-dampness; cape jasmine fruit and baikal skullcap root for heat excess; peach seed and Radix Paeoniae Rubra for blood stasis; Curcuma wenyujin, Akebia trifoliata and Bupleurum chinese for qi stagnation. A total of 19 pairs of couple herbs were summarized by the cluster analysis.

[Objective] To compare and analyse the clinical effect of tiny incision blind-cut suck-erasion on unhairing and preserving armpit hair in bromhidrosis.[Method] Select 429 cases of 851 sides in our hospital, divide them into treatment group(blind-cut suck-erasion+unhairing) 308 cases with 609 sides, and control group(blind-cut suck-erasion+preserving armpit hair) 121 cases with 242 sides. Make statistics and compare their complications in recent and forward stages, also the recurrence and residual of peculiar smel after 1 year. [Result] For the treatment group, 38 sides had the recent compli-cation of hematoncus, 30 sides had partly skin necrosis, 12 had bad cut cure, 70 had early slight hardening and contracture skin; for the forward complica-tions: 27 sides had focal slight scar, 3 severe scar, 23 focal subcutaneous sac lump with infection, 3 peculiar smel residual and recurrence. To the control one, for the recent complications, 11 sides had hematoncus, 9 partly skin necrosis, 5 bad cut cure, 13 early slight hardening and contracture skin; for for-ward complications, 8 sides had focal slight scar, 1 severe scar, 3 focal subcutaneous sac lump with infection, 38 peculiar smel residual and recurrence. By comparison, on early slight hardening and contracture skin and focal subcutaneous sac lump with infection, the treatment group was higher than control one;other complications had no difference of statistical meaning;on radical cure rate, the treatment group was obviously more than control one, with dif-ference of statistical meaning. [Conclusion] The tiny cut blind-cut suck-erasion is definite in treating bromhidrosis, the operation removes subcutaneous apocrine sweat gland, meanwhile removes the hair fol icle and sebaceous gland complexus, the therapy is very thorough, with better cure effect, less recur-rence, without increasing complications.

Objective To explore the pertinent communication strategy of health education for parasitic diseases.Methods A cross-sectional study was carried out.Before the health education intervention,the knowledge,attitude and practice(KAP)for parasitic diseases of 199 and 250 farmers in two provinces of Sichuan and Yunnan in southwest China were investigated with questionnaire by using the method of PPS.Results Most of the farmers used the simple and crude toilets and their health status were poor,and there were only 7.57% of people having the bio-gas facilities.The awareness rate of the knowledge on malnutrition caused by parasitic diseases was 34.30% and the awareness rate of knowledge about anemia caused by parasitic diseases was 29.62%.There were 81.74% of farmers who believed helminthic drug and 74.61% of people who tended to buy drug by themselves.The health knowledge of the residents mainly came from the interpersonal communication and TV,and the farmers preferred TV,poster and brochure to get the health knowledge.Conclusion The health education with posters,TV and intervention communication is one of the important measures to control parasitic diseases.
