Congenital cataract is one of the leading causes of children vision impairment and blindness.Among the many causative factors,inheritance plays a critical role in the development of congenital cataract.With the development of molecular biology techniques,more than 30 genes have been found to be associated with congenital cataract,and the number is still increasing.More pathogenic genes discovery and functional researches have the important values to understand the lens biological characteristics and the cataract pathophysiology mechanism.Discovering new ways to prevent cataracts may make it possible for human to achieve individualized genetic intervention.This article reviewed the recent advances in the study of lens embryology and genes related to congenital cataract.

Angiotensin Ⅱ and type 1 receptor ( AT1R) are ab-solutely therapeutic targets in the hypertension and cardiovascular disease, and angiotensin Ⅱ gets involved in monocytes chemo-taxis and migration, T lymphocytes activation and proliferation, Th1 and Th17 immune function, and synoviocytes apoptosis inhi-bition in patients with rheumatoid arthritis ( RA) through binding to AT1R in the autocrine and/or paracarine manner. Drugs that limit angiotensin Ⅱ production by angiotensin converting enzyme inhibitors ( ACEIs) or blockade of angiotensin Ⅱ-AT1R action by AT1R blocker ameliorate immune and inflammation responses in RA patients. Additionally, angiotensin Ⅱ type 2 receptor (AT2R) expression increases in RA and experimental model, and activation of AT2R exerts a therapeutic effect on adjuvant-in-duced arthritis. AngiotensinⅡand its receptors in RA and auto-immune diseases are retrospectively reviewed in this paper.

Objective To analyze and study the relationship between plasma adhesion molecules,free amino acids and ovarian cancer.Methods A total of 67 patients with ovarian cancer in our hospital during the time of March 2015 to May 2016 were selected as the observation group,and 67 healthy women at the same time were selected as the control group.The plasma adhesion molecules and free amino acids levels of two groups were detected and compared,The detection levels of observation group with different stages and degree of differentiation of ovarian cancers were compared.The relationship between plasma adhesion molecules,free amino acids and ovarian cancer were analyzed by the Logistic analysis.Results The plasma adhesion molecules levels of observation group were all higher than those of control group (P ＜ 0.05),the plasma free amino acids levels were all lower than those of control group (P ＜ 0.05),and the detection levels of observation group with different stages and degree of differentiation of ovarian cancer plasma adhesion molecules and free amino acid levels had significant differences (P ＜ 0.05).The Logistic analysis showed that the plasma adhesion molecules and free amino acids had close relationship to the ovarian cancer (all P ＜ 0.05).Conclusions The plasma adhesion molecules and free amino acids of the patients with ovarian cancer show abnormal expression state,and the expression levels of patients with different stages and degree of differentiation of ovarian cancer have certain differences,so the detection value of those indexes in the patients with ovarian cancer is higher.

OBJECTIVE: To provide proposal for government on dealing with the relationship between commercial and social property of drugs.METHODS: Multi-stakeholders subjects and their interrelation in the listing decision of drugs were investigated using game model.RESULTS & CONCLUSIONS: Innovation level of pharmaceutical industry (P),profitability of drugs operator (E),other factors affecting the proceeds of drug operators (K),additional gold cost of drugs (C1),additional cost of gold drugs sale (C2) were confirmed to be the key factors which affected the listing decision of drugs by pharmaceutical manufacturers.Governments are suggested to ensure the rational and fair use of drugs in public by policy supports,encouraging drug innovation and make-up on difference of drugs in medical institutions,optimizing benefit components of medical institutions,creating evaluation criteria for "listing value" and "necessity in clinic" of drugs.

OBJECTIVE To save rust remover's cost,reduce the material consuming and ensure the cleaning quality of the instruments by changing the work model.METHODS According to the key factors of the increasing cost of the medical rust remover,adjust the work model properly,that is to say,set up target by know about the problems;confirm the measurement data of the problems;analyze the problems and figure out key minority;make strategy to correct the mistakes;and make the controlling measures to ensure effective implementation.Enforce organization management,and remove the rust collectively and grouply by time,by ration and by certain number of people.RESULTS The rust remover cost had been saved greatly and the cleaning quality had been improved distinctly,the number of scrapped medical instrument had been reduced.Compared with the period before improvement,it had statistic significance on difference(P

OBJECTIVE To study the influence of various packing methods and controlling method toward the hidden wet pack after steam sterilization to ensure the sterilization quality and hygiene safety.METHODS The medical equipment was packed with three types of methods,then unloaded from the steam autoclave after being cooled at different time to observe their heating speed respectively.To choose two types of cotton fabric packaging methods,prolong the heating time,and cool in the steam autoclave for 30 minutes,then observe the heating speed of the inside pack and the dry qualification status after 12 hours respectively.RESULTS The heating speed was the fastest with the medical crinkly paper method;the heating speed of the inside pack didn't have any improvement after prolonging the heating time;the dry qualification rate had distinct difference between the two types of cotton fabric methods after 12 hours(P

OBJECTIVE To explore the two application methods of medical lubricant oil to avoid the high cost and secondary contamination problems.METHODS The spray and immersion methods of lubricant oil to maintain the medical equipment were adopted and compared its bacterial reproducing status after dilution and weekly oil cost.RESULTS The spray method was better than the immersion method,The bacterial reproduction was not found by the oil spray method for over 48 h and the weekly lubricant oil dosage was 200 ml,but in the immersion method the bacterial contamination rate was 100% at the sametime in its dilnted oil and the weekly lubricant oil dogase was 800ml.CONCLUSIONS For the manual method to wash the equipment,spray method can maintain the equipment to avoid the secondary contamination problem and save the lubricant oil dosage and cost.

Wtth the development of imaging technique,particularly the use of magnetic resonance diffusion weighted imaging,it can easily detect silent stroke lesiom.Both the prevalence and incidence of asyrrotomatic stroke were higher than those of symptomatic stroke.Age,hypertemion and atrial fibrillation are its accepted risk factors.Although silent stroke lacks clinically overt stroke-like symptoms by definition,it often has mild physical and cognitive impairment with careful examination.Furthermore,asymptomatic stroke is also correlated with the occurrence of subsequent symptomatic stroke.decreased cognitive function and dementia.Therefore,clinicians should pay more attention to it,positively control its risk factors and improve its prognosis.

Microwave ablation(MWA) is a significant progress in tumor non-surgical treatment in the 1990s.It is characterized by high thermal efficiency,fast heating rate,high uniform temperature field,complete necrosis of coagulation area and small influencing factors.The local treatment of the tumor shows a great advantage.In recent years,with the maturity of MWA technology,it has been widely used in the treatment of liver tumors(hapatic tumor,HT),has achieved good clinical efficacy.The aim of this study is to review the progress of treatment of HT in MWA to improve its therapeutic efficiency.
