Medical laser adopts optical fibers as spread media, using laser energy for the purpose of diagnostics and therapeutics. The corresponding industry standard is YY/T 0758-2009 General requirements for therapeutic laser fiber, which requires manufacturers to offer applicable wave length (or spectrum range) of the fiber, and the corresponding minimum transmission efficiency of the wave length. This research focuses on the matching of therapeutic laser fiber and laser source, to support and emphasize the importance and reasonability of relative requirements in YY/T 0758-2009.

[Objective] To clear up Ms. He Jialin's recipe cases in treating gestation diseases, sum up her diagnosis and treatment thought and medication principle. [Method] Make mutual corroboration of doctor He's medical prescriptions and TCM classical theories and formulae, to explore He's experience of diagnosis and theoretic origin. [Result] Doctor He has rich experience in diagnosing and treating gestation diseases, with clear thought, and principle-method-recipe-medicines, wel-founded, closely observing disease development, considering the situation, using drugs as military forces, with consolidate steps. [Conclusion] Doctor He diagnosing refractory diseases, learning from ancient but not rigidly adhering to ancient, ful y embodies the treating principletoxic drugs'good effect on diseased body.

It is of great importance to have a correct understanding of what is meant by governmental purchasiug and the system of governmental purchasing. The authors first expound the connotation and extension, characteristics and forms of governmental purchasing and the significance and necessity of centralized drug purchasing. Then they focus their discussion on the specific procedures of centralized drug purchasing. Finally they point out that it is imperative to seek unity of thinking, standardize operations, adopt institutionalized means of management, and make a really good job of centralized drug purchasing.

OBJECTIVE: To summarize the advances in the genetic susceptibility to coronary artery disease (CAD) and explore the heritable basis of the disease.DATA SOURCES:Related articles in English from January 1990 to June 2006 were searched in Pubmed and EMCC databases with the terms "gene, coronary artery disease and myocardial infarction". Meanwhile, the CMCC database was searched for the relevant articles published between January 2000 and June 2006 in Chinese.STUDY SELECTrON: After the preliminary selection,relevant literatures on genetics of CAD and myocardial infarction(MI)were selected, and those with obvious indifferent contents or with less correlation were excluded.DATA EXTRACTION: Data of 49 articles were mainly extracted from the selected literatures providing solid evidence to elucidate the genetic susceptibility to CAD or MI.DATA SYNTHESIS: The involved 49 articles showed that CAD is a complex multifactorial disorder which is believed to result from the interplay between a person's genetic makeup and various environmental factors. The heritable basis is increasingly recognized as a crucial component in the development of CAD. Recent work in the field of genetics has lead to determining key genes associated with the susceptibility for CAD and MI through genome-wide linkage scans and large-scale gene-association studies as core human genetics approaches These susceptibility genes involve diverse functions, including dyslipidemia, vascular homeostasis, endothelial dysfunction, inflammation and immunity.CONCLUSION: The identification of genes that predispose to or directly cause CAD provides new insights into the pathogenesis of this disorder. However, the precise role of genetic factor in the CAD or MI events and the personalized gene-specific therapy await further investigation.

In this paper the investigation of using a new method-ABC-ELISA in assay of Autoimmune Thyroid Disease are presented. The sensitivity of ABC-ELISA is compared with that of standard ELISA; Its reliability is proven by the methods of detecting TSAb with FRTL-5. TRAb is detected by ABC-ELISA in 91% of untreated Graves'. TRAb is detected by Standard ELISA in 70% of untreated Graves'. The results of ABC-ELISA in 26 untreated Graves' are equal to that of the method of detecting TSAb with FRTL-5. Therefore, we consider that ABC-ELISA is a sensitive, reproducible, convenient method applicable to clinical practice.

Objective To explore the effect of air pressure wave on the prevention of lower limb deep venous thrombosis in patients with cerebral stroke and the application value of color Doppler ultrasound (CDUS).Methods 72 stroke patients were randomly divided into experimental group (n =37) and control group (n =35) by random digits table.The control group received routine nursing,conventional and rehabilitation therapy.The experimental group was treated by the air pressure wave for 15 days on the basis of the control group.DVT formation of lower extremities and hemodynamic changes before and after treatment was observed by CDUS,and the results were compared with the X-ray phlebography examination results.Results CDUS displayed the incidence rate of DVT in the experimental group was significantly lower than that in the control group (2.7％ vs 20.0％,x2 =5.449,P ＜0.05).The changes of blood flow velocity and the average reflux time of femoral,popliteal vein in the experimental group had significant differences between before and after treatment (t =8.503,4.254,8.587,2.062,all P ＜ 0.05) ;and in the control group,only popliteal vein blood flow velocity had statistically significant difference (t =6.895,2.116,4.169,all P ＜ 0.05).Compared with the X-ray angiography,8 cases of DVT diagnosed by CDUS were consistent,but 1 case of DVT in the control group was missed diagnosis.Conclusion Air pressure wave can effectively reduce the occurrence of DVT in patients with cerebral stroke.CDUS can accurately diagnose the DVT formation,and can help to understand the hemodynamic change,it has important clinical value for monitoring the preventive effect of DVT.

Objective] To introduce Professor He Jialin's experence in treating abdominal mass with infertility. [Method] Through years of clinical learning from teacher, summarized the teacher's academic thoughts and the experiences of diagnosis and treatment. It expounds her special clinical experience from etiology and pathogenesis, fundamental law of treatment, medication characteristic, and classical proven cases. [Result] The disease covers a broad range. The typical syndromes are damp heat, phlegm, blood stasis. And blood stasis is most important. The fundamental law of treatment includes strengthening the body resistance, removing blood stasis, reducing phlegm and resolving masses, regulating menstruation. Doctor He combined traditional Chinese and western medicine, considering the comprehensive, combined with the individual constitution, emphasized the selection of herbal medicine with multiple functions. The clinical effect in the proven cases was amazing. [Conclusion] Professor He had rich experience treating abdominal mass with infertility, which might be used as reference data in clinical medicine.

Epidemiological studies have shown that human papillomavirus (HPV) infection is the main cause of cervical cancers and cervical intraepithelial neoplasia(CIN).And different types of HPV have different carcinogenicity,different cervical cancer pathological types and prognoses of cervical cancer.The effective way to decrease the cervical cancer morbidity is to detect and classify the high-risk HPV infection in early time,and carry out intervention therapy in early time.Therefore,detecting HPV subtypes in clinic will have great significance in prevention and treatment of cervical cancer and cervical precancerous.
