Objective To understand the attitude of health workers towards people living with HIV and AIDS(PLWHA) and AIDS knowledge and desire for related training among them in selected hospitals in Beijing.Method Convenience sampling was used to select health workers from 32 hospitals of different levels in 4 districts within Beijing.Anonymous self-administrated questionnaires were used to collect the information regarding AIDS knowledge and desire for relevant training.Results A total of 1 292 health workers completed the questionnaire.They demonstrated a moderate level of general AIDS knowledge,but a low level of knowledge related to AIDS diagnosis and therapy.Of them 39.7% had received specialized AIDS training and 96% had strongly desire for such specialized training.Most health workers sympathized with PLWHA and understood their situation,while some of them were afraid of PLWHA and wanted to have minimal contact with PLWHA.91.3% of the health workers expressed that PLWHA should have the same rights to medical services.At the same time,49.2% of the health workers stated that they would not like to work in hospitals or departments which accepted PLWHA.80% of the health workers expressed concern over acquiring HIV infection in the workplace.52.7% of them thought that they had a risk of becoming infected in the workplace.Conclusion The level of AIDS knowledge among health workers in Beijing needs to be improved.Specialized training to enhance and develop health workers knowledge of prevention,diagnosis and treatment of AIDS is required.Most of the health workers do not discriminate against PLWHA,but they express concern over infection in the workplace.

Objective To evaluate the risk of cardiovascular adverse events using nonsteroidal anti-inflammatory drugs during the perioperative period.Methods A systematic review of formally published in English and Chinese literature was conducted by using computerized database on PubMed, Web of Science, Medline, Cochrane Library, CNKI and Wanfang database.The literature about controlled clinical study of nonsteroidal anti-inflammatory drugs in perioperative use, a prospective cohort study and a retrospective review were collected.The cardiovascular risk was evaluated by the number of adverse cardiovascular events cases (myocardial infarction, angina, myocardial ischemia, arrhythmia) occurred during the period of drug use.The relevant data was extracted and their heterogeneity was tested.Results A total of 8 articles including 15 623 patients met the inclusion criteria, including 5 articles (n=13 019) on non-selective nonsteroidal anti-inflammatory drugs, and 3 articles (n=2 604) about selective (cyclooxygenase 2) COX-2 inhibitors.Nonsteroidal anti-inflammatory drugs used in the perioperative or a short term would reduce the risk of adverse cardiovascular events (OR=0.59, 95%CI 0.45-0.77, P=0.000 1), non-selective nonsteroidal anti-inflammatory drugs using in the perioperative or a short term would reduce the risk of adverse cardiovascular events, the difference being statistically significant (OR=0.42, 95%CI 0.31-0.58, P＜0.001).A selective COX-2 inhibitor using in the perioperative or short-term might increase cardiovascular adverse events (OR=2.53, 95%CI 1.26-5.09, P=0.009).Conclusion Non-selective nonsteroidal anti-inflammatory drugs should be chosen for patients at high risk of adverse cardiovascular events during the perioperative period.

Diabetic nephropathy is one of the most serious complications of diabetes mellitus and it seriously endangers people's health.Some previous studies indicate that the occurrence and development of diabetic nephropathy is not positively associated with control of blood glucose and course of disease,Its development has family aggregation and ethnic differences.In addition to environmental factors,genetic factors play an important role in the process of occurrence and development of diabetic nephropathy,Many genetic mutations can lead to a high degree of susceptibility to diabetic nephropathy.Discovery of some related genes of diabetic nephropathy and elucidation of these genes function provide an effective means in the early diagnosis,gene therapy and individualized drug therapy of diabetic nephropathy.In this review the action and function of discovered related genes of diabetic nephropathy are summarized.

Objective To investigate the change of neutrophil elastase and matrix metalloproteinase-9 in sepsis and determine significance in the early diagnosis and prognosis of multiple organ dysfunction syndrome.Methods The plasma levels of neutrophil elastase and matrix metalloproteinase-9 in 28 ICU patients with sepsis were examined by immunofluorescence.Results Compared with control group,the levels of NE and MMP-9 were significantly higher on the day of the diagnosis of sepsis(P

All of the thrombolytic agents currently approved for use in humans are plasminogen activators, the application of which is limited by bleeding complications at vascular injury sites and plasminogen content in the thrombus. Plasmin is rapidly neutral-ized in the circulation by α2-antiplasmin and tolerated without bleeding. With the application of catheter-based delivery, the unique bio-chemical properties of plasmin make it a safe and effective direct fibrinolytics. Plasmin derivatives, including miniplasmin,Δ-plasmin and microplsmin, display more thrombolysis efficacy and better hemostatic safety in preclinical study and clinical trials. This review sum-marizes the current information on plasmin and its derivatives, including the advances on biochemical properties, preclinical and clinical trials.

Objective To explore the features of clinical manifestations and electrophysiology of spinal muscular atrophy(SMA) in children.Methods The clinical features and laboratory data were analyzed in 32 children with SMA,electromyography tests were carried out in 28 patients and the muscle biopsy were performed in 24 cases.Results The 32 cases were subdivided into 3 clinical groups,15 cases were SMAⅠ,12 cases were SMAⅡ,5 cases were SMAⅢ.They were all characterized by progressive muscle weakness associated with hyptonia and atrophy.The clinical distinction between SMAⅠto SMAⅢ reflected different age of onset and disease severity.All cases of SMAⅠhad symptoms of respiratory disability,only 1 case of SMAⅡ had paradoxical breathing and none of SMAⅢ had similarly symptoms.Electromyographic studies showed a pattern of denervation with no sensory involvement.The rate of spontaneous potential was 87%,with gentle strain,the duration of motor unit was extended(30%-150%) and the amplitude of it was increased(90%-450%),the motor nerve conduction velocity was reduced slightly in 28% patients.The muscle biopsy provided evidence of skeletal muscle denervation with groups of atrophy.Conclusions The clinical features,the changes of electromyography and the muscle biopsy are valuable for diagnosis of SMA.Respiratory management will prolong survival and improve the quality of life for these patients.

AIM: To analyze the effect of myopic adolescents wearing orthokeratology lens on the corneal surface curvature radius and anterior chamber depth.METHODS: Totally 120 cases of adolescent myopia were selected, among them 58 cases with 116 eyes were divided into 11-14 years old group and 62 cases with 124 eyes were 15-18 years old group according to the age.They were treated with long-term orthokeratology lens treatment, and two groups of patients were observed before wearing lens(T0), wearing for 6mo (T1), 12mo (T2) for uncorrected visual acuity, the average refractive degree improvement, the central corneal thickness, corneal curvature changes and the incidence of complications.RESULTS: The uncorrected visual acuity of the two groups at 12mo after wearing were better than that at 6mo which was better than that before wearing;the diopter had the same trend.The uncorrected visual acuity and the diopter of the 11-14 years old group at 6 and 12mo was better than those of 15-18 years old group with significant difference (P<0.05).The central corneal thickness of the two groups at 12mo after wearing were less than that at 6mo which was less than that before wearing.There was no significant difference of the central corneal thickness between the two groups at 6 and 12mo after wearing (P>0.05).The corneal anterior surface curvature of the two groups at 12mo after wearing were more than that at 6mo which was more than that before wearing.The axial length of the 11-14 years old group was longer than that of the 15-18 years old group with significant difference (P<0.05).There was no significant difference on the corneal posterior surface curvature of the two groups before and after wearing (P>0.05).There was no significant difference on the anterior chamber depth between the two groups at different time or between before and after wearing (P>0.05).CONCLUSION: Long-term wearing orthokeratology lenses have a significant effect for control ling juvenile myopia, and can improve the corneal anterior surface curvature, especially in the lower age group, and has no significant effect on the anterior chamber depth.
