ObjectiveTo analyze the relationship among depression and anxiety and other possible factors in post-stroke patients.Methods510 hospitalized stroke patients from 1997 to 2004 were evaluated with the Scale of Elderly Cognitive Function (SECF), Self-Rating Depression Scale (SDS), Self-Rating Anxiety Scale (SAS), and Activities of Daily Living (ADL) in 7 days after admission and re-examined after two months.ResultsThe depression group exhibited the longer course of disease, a high ratio of hemiplegia in left side, lower ADL scores and higher SAS scores at time of admission. There were significant differences between depression and non-depression group. However, there was no significant difference between the depression and cognitive function. There were also significant differences between anxiety group and non-anxiety group. Patients with anxiety displayed symptoms of low ADL scores and higher SDS scores at time of admission, and ADL scores increased after treatment. Additionally, the course of disease was longer and reduction of anxiety level was lower. The levels of depression and anxiety significantly reduced in depression group and anxiety group when compared to the control group.ConclusionEarly rehabilitation can help to reduce depression level. Modest anxiety may help stroke patients to improve their ADL. There is close relationship between depression and anxiety.

ObjectiveTo compare the effect of psychological treatment only and psychological combined with fluoxetine treatment in reducing symptom of depression, anxiety and in improving of cognitive and daily living abilities for post-stroke depression patients.MethodsAll patients with post-stroke enrolled in hospital between 1996 and 2001 and were evaluated by using of the Self-rating Depression Scale (SDS), the Self-rating Anxiety Scale (SAS), Scale of Elderly Cognitive Function (SECF), and Ability of Daily Living (ADL). SDS score was equal or greater than 50 points (SDS≥50) selected as subjects for this study. A total of 115 patients were randomized divided into psychological with fluoxetine treatment group (Group A,54 patients) and psychological treatment group (Group B,61 patients). There is no significant difference between two groups in age, education, and left or right side of hemiplegics. Statistical analysis was performed by using Chi test and t test to compare the 2 groups at day 0 (baseline) and after 2 months.ResultsThe level of depression and anxiety reduced significantly in both Group A and Group B from baseline to end of treatment (P<0.001). Both groups had significant improvement in daily living ability (P<0.001).There was no significant improvement in cognitive ability (P>0.5). There was no significant differences on SDS, SAS, SECF, and ADL scores from baseline to end of treatment (P>0.5).Conclusions There were similar effect of psychological with fluoxetine treatment and of psychological treatment only on post-stroke depression.

Objective To analyze the injury mechanism and distribution of the motor vehicle engine shake shaft caused injuries (MVESSCI) in North Henan province. Methods A follow up was done on 520 patients with the motor vehicle engine shaft injuries treated in our hospital from January 1998 to May 2002. The epidemiological features were analyzed concerning gender, age, injury time and injury sites. Results There were 300 males and 220 females (age range of 9-53 years, mean 31 years) with ratio 1.36 ∶1 of male to female. The MVESSCI were dominated by Colles fractures and distal fractures of ulna and radius, accounting for 73.8% (384/520). The traffic accidents occurred most in May, June, September and October, which accounted for 85.0% (442/520). Conclusions (1) The vehicle engine shake shaft causes the injuries mainly at the distal part of the right forearm, mainly the Colles fracture and the distal fractures of ulna and radius. (2) The injury is mainly due to improper operation in busy farming seasons. (3) The countermeasures to reduce wounds and injuries are to pay much more attention to prevention, strengthen the safety awareness of individuals, improve the structures of motor vehicles and avoid improper manipulation of the vehicles by children.

A biosensor is made from a biological sensing element attached to a signal transducer.Biosensors have many outstanding virtues such as portable,simplicity of operator and lowconsumption.Also,biosensors could provide fast,real-time and accurate results.Therefore,biosensors have been implemented for a number of applications in molecular diagnostics.We have summarized the recent progress in the research and application of biosensors in the field of molecular diagnostics for pathogenic micro-organism,drug testing and genetics.

Objective To study the correlation of serum CA125 level and differentiation of endometriosis (EMs) and pelvic pain due to Ems.Methods The clincal data of 305 EMs patients were retrospectively analyzed,and they were divided into I,Ⅱ,Ⅲ,Ⅳ four stage according to r-AFS.The relevance of preoperative serum CA125 and differentiation of Ems and pelvic pain were assessed and statistically analyzed.Results The serum CA125 level was higher in Ⅲ,Ⅳ stage (69.4 ± 5.7) U/ml,(171 ± 11.5) U/ml than that in Ⅰ,Ⅱ stage (14.8 ± 1.2) U/ml,(36.3 ±3.0) U/ml,there was statistically significant difference (P ＜ 0.05).The positive rate of CA125 increased progressively (12.1％,21.5％,40.2％,63.9％),but the difference was not statistically significant(P ＞ 0.05).The pain syndromes in the clinical features of differentiation of Ems had obvious difference (P ＜ 0.05).Conclusion The serum CA125 detecting can be used in differentiation of Ems,and it has important value in diagnosis and prognosis of EMs.

The characteristics of distribution and shapes of polluted particles in openning infusers and several kinds of infusion containing drugs were observed microscopically. According to the specification of Chinese Pharmacopoeia 1985 the examination was carried out under simulated conditions of infusion in a ward. The results indicated that both the infusers and the infusions containing drugs were polluted by a great deal of particles.

Diabetic retinopathy (DR) is a common disease of ophthalmology,often causes irreversible decline of patients' vision,which has two features including macular oedema,diabetic retinal neovascularization.Diabetic retinal neovascularization is one of the most important reasons leading to blindness.Endostatin (ES) is one of the most effective agents inhibiting angiogenesis,whose biological function has a close relationship with its chemical construction.However,its mechanisms of treating diabetic retinal neovascularization are very complicated and remain unclear.Therefore,in this review we summarized several possible mechanisms,including regulating the expression of extracellular matrix,inhibiting the expression of pro-angiogenic factors,and regulating the signaling pathways,by which ES may inhibiting diabetic retinal neovascularization.

The article points out that to improve the teaching quality and level of national medical colleges and universities,the experience of Medical College of Monpillier University,France should be introduced and learned from.Views and suggestions are also put forward to counter the existing problem in national medical teaching system and clinical practices.

Medical tourism, which is a new type of tourism activity with the combination of health and sightseeing, has become the new economic growth point of the tourism industry.Through a systematic literature review, the present paper analyzed the influencing factors and effects of medical tourism, as well as the behavior of medical tourists and relevant stakeholders of medical tourism.Further researches could combine qualitative and quantitative methods, and emphasize on the behavioral characteristics of medical tourists.In order to promote the development of medical tourism, we should increase the medical service qualities, promote the internationalization of medical tourism, introduction of special medical tourism products;improve medical tourism policies, regulations and laws;promote medical tourism through a strategic marketing and the role of relevant stakeholders of medical tourism should be paid attention on, and other measures to promote the healthy development of China''s medical tourism.
