Objectives Appraise the quality of retired workers' life of a medical college according to their income, livelihood, neighborhood relations, health condition and other related factors. Methods Fill in the Quality of Life Investigation Questionnaire when the retired workers are taking routine physical examination. Results 776 pieces of questionnaire were collected, making up 64.7% of the retired workers, which may represent the people of this kind. Out of the 776 retired workers, 597 are suffering from chronic diseases, making up 76.9%. Among them, 37.5% have one type of chronic disease, while 39.5% have two types and more. Among them, heart cerebrovascular diseases and hypertension sufferers occupy 80.6%, 63.3% of the overall prevalence rate. 42.2% are satisfied with their health condition, 9.6% are not, 48.2% with fair contentment. Those with positive view towards income take up only 41.4%, while negative 6.6%. As to the way of living, 375 are living either with a spouse or by oneself, making up 50.6% ,while 46.2% living by a core family with children and grandchildren or with a big family. 64.0% are able to take care of themselves. Among the 236 in need, 88.0% are taken care of by relatives, only 12% by social aids. About 82.5% enjoy a harmonious family life;only 0.5% are not. 83.0% keep a good neighborhood relationship, only 0.6% of them doesnt. Conclusion The overwhelming majority of the retired workers of senior teachers and scientific and technical personnel are living in a harmonious family or community. When they are in need, relatives are the main forces to help, social forces does not work much on it. Two items that below 50% of the satisfaction are income and health condition. So, we are looking forward to the improvement of these two aspects by the reform on social and medical insurance.

Objective To compare the clinical effect of different dose dexamethasone on acute low-frequency sensorineural hearing loss (ALHL).Methods 266 cases with ALHL were randomly divided into treatment group (136 cases) and control group (130 cases).On the basis of the comprehensive treatment,the treatment group received dexamethasone 40mg/d intravenous infusion,the control group was given dexamethasone 20mg/d.The treatment effect,average hearing threshold and recurrence were compared between the two groups.Results In the treatment group,the cure rate was 30.8％ (42/136),the effective rate was 50.0％ (78/136),invalid rate was 19.2％(36/136),the total effective rate was 80.8 ％.In the control group,the cure rate was 26.1％ (34/130),the effectiverate was 52.2％ (68/130),the invalid rate was 21.7％ (28/130),the total effective rate was 78.3％,the total effective rate between the two groups had no statistically significant difference (x2 =0.14,P ＞ 0.05).After treatment,125Hz,500Hz band,the average hearing threshold between the two groups had statistically significant differences (P ＜0.05).19 patients relapsed (19/120) in treatment group,the control group had a recurrence of 8 patients(8/102),the recurrence rate between the two groups had statistically significant difference (t =2.241,P ＜ 0.05).Conclusion Dexamethasone has good effect in treatment of ALHL.Small dose dexamethasone can reduce the recurrence rate and has no serious complications.

Objective To explore the significance and clinical value of continuous intracranial pressure monitoting in the treatment of brain injury.Methods 60 patients with severe brain injury were randomly divided into group of 30 patients (conventional treatment + continuous intracranial pressure monitoring), control group 30 patients( conventional treatment) ,disability,rate of successful treatment and efficacy renal function were compared after given mannitol. Results The loss rate of the observation group was 13％, and was lower than that of the control group (33％) (P ＜0. 05) :The successful rate of the observation group was 20％ ,and was higher than that of the controlgroup( 10％ )( P ＜ 0. 05 ). Conclusion In patients with severe brain injury, intracranial pressure monitoring was effective to reduce renal damage and reduce the loss rate increase treatment efficacy.

OBJECTIVE To explore the main risk factors of fungal infection in lower respiratory tract(LRT) of hospital patients,strains distribution and sensitivity to common antifungal agents so as to provide basis for earlier diagnosis and effective treatment.METHODS Retrospective analysis was taken of the 76 cases with fungal infection in LRT in patients of Taizhou Hospital from Jul 2004 to Jun 2006 based on the diagnostic criteria for nosocomial infections by Ministry of Health of PRC and also following the definition given by European Organization for Research on Treatment of Cancer(EORTC) and us Mycosis study Groap(MSG) in 2002.RESULTS Of the 76 cases,84.2% were over 60 years old.All of them had underlying diseases.Sixty cases had been repeatedly treated with 2 or 5 antibiotics before fungal infection;21 cases received glucocorticoid;6 cases had chemol and radiotherapy and 21 cases underwent invasive treatment procedures.In the three years,77 strains of fungi were isolated from all kinds of samples.Susceptibility testing indicated that the resistance to ketoconazole and miconazole was higher compared with that to fluconacole and itraconazole.CONCLUSIONS Fungal infection in LRT of hospital patients is closely related with age,long stay in hospital,wide administration of broad-spectrum antibiotics,immuno-suppressants and cytotoxic drugs.The most common fungi are Aspergillus and Mucor.There is an increasing number of strains of fungi resistant to drugs,especially to azole antifungal agents.Effective counter measures should be taken without delay.

Object To study the chemical constituents from fruiting bodies of Ganoderma lucidum (Leyss ex Fr.) Karst Methods Individual constituent was isolated and repeatedly purified on silica gel column and structurally elucidated by the NMR spectra and X ray diffraction analysis Results Four compounds were obtained from the alcohol extract and identified as 3? oxo formyl 7?, 12? dihydroxy 4, 4, 14? trimethyl 5? chol 11, 15 dioxo 8 en (E) 24 oic acid (Ⅵ); 3? oxo formyl 7?, 12? dihydroxy 5? lanost 11, 15, 23 trioxo 8 en (E) 26 oic acid (Ⅶ); ergosterol (Ⅷ) and ergosta 7, 22 dien 3? ol (Ⅸ), respectively Conclusion Compound Ⅵ and Ⅶ are new triterpenes

Nowadays,more and more basic and clinical researches on absorbable internal fixators are car- fled out in China.This paper reviews the recent researches on biodegradation,absorption,and mechanical prop- erties of absorbable internal fixators,their effects on bone mineral density and structure and injury of epiphyseal plate,and their clinical applications.Some problems that have not been solved and future research key points are highlighted and discussed.

Fundamental specialized courses are important due to their connection between fundamental knowledge and major knowledge,which are regarded as the difficult courses for undergraduates to learn.The useful approaches and experience of bilingual teaching in microbiology,one of the fundamental specialized courses for the students majoring in Bioengineering,are presented here.The key aspects such as choosing textbooks,teaching manners and teaching contents are also discussed.This paper also proposes how to improve the quality of bilingual teaching during the fundamental specialized courses.

Objective To determine the optimum water-extracting technology of Mailuoning injection. Methods The orthogonal test was used to select the water extract technology of Mailuoning injection. Results The best technology was that crude drug was added 12 and 8 times water, then soaked 0.5 h, and extracted for l.5 and 1.0 h. Conclusion The study of technology provides the basis for further purification.

To compare the efficacy on miyalisa n with ribavirin in the treatment of infants' diarrhea. Methods: 152 infants with diarrhea in outpatient department were divided into two groups treated with miyalisan (80 cases) or ribavirin (72 cases) for 3 days. The therapy could be continued for another 3 days if necessary. Results : The Clinically effective rate and the negative conversion rate of rotavirus in the treated group and controlled group were 93.8% and 87%, 82% and 60%, respectively, there were sinnificantly different(P＜0.05) between two g roups. Conclusion: Miyalisan had showed a better efficacy in treatment of infants' rotavivus enteritis than ribavirin.

Lyme disease is continuing worldwide spread and its prevalence still presents raising tendency.The causative agent is Borrelia Burgdorferi(Bb) and the special biological intermedia is ixodid ticks(Ixodes scaputaris).The current study on the genetic strain of Bb and the interpretation of laboratory diagnosis(microscopic,immunologic and biomolecular test)results as well as the preparation of vaccine for the disease are made in this review.
