用眼A／B超声仪诊断眼伤残疾病

带有10MHzA、B探头，日本产Nidek US-3000型超声仪．分辨率高，可以在无任何副损伤及不适情况下直接对眼球、眼附属器及眶内状态进行A、B、A／B超声检测。我科自1992年6月至1993年5月应用该超声仪对其他检查技术难以确诊的59例眼伤残病人进行了检查．诊断准确率达98％，说明利用眼超声拄术观察眼球形态学变化．对球(眶)内异物、肿瘤、外伤等诊断，对拟植入人工晶体选择合适屈光度方面有独到之处，为眼伤残疾病治疗为防盲工作的开展提供了方便条件。

Impact of disease severity on gastric residual volume in critical patients

AIM: To investigate whether illness severity has an impact on gastric residual volume (GRV) in medical critically ill patients. METHODS: Medical intensive care unit (ICU) patients requiring nasogastric feeding were enrolled. Sequential Organ Failure Assessment (SOFA) score was assessed immediately preceding the start of the study. Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ scores were recorded on the first, fourth, seventh, and fourteenth day of the study period. GRV was measured every 4 h during enteral feeding. The relationship be-tween mean daily GRV and SOFA scores and the correlation between mean daily GRV and mean APACHE Ⅱ score of all patients were evaluated and compared. RESULTS: Of the 61 patients, 43 patients were survivors and 18 patients were non-survivors. The mean daily GRV increased as SOFA scores increased (P < 0.001, analysis of variance). Mean APACHE Ⅱ scores of all patients correlated with mean daily GRV (P = 0.011, Pearson correlation) during the study period. Patients with decreasing GRV in the first 2 d had better survival than patients without decreasing GRV (P = 0.017, log rank test). CONCLUSION: GRV is higher in more severely ill medical ICU patients. Patients with decreasing GRV had lower ICU mortality than patients without decreasing GRV.

Self-harm attempters' perception of community services and its implication on service provision

Objective:This study aimed at exploring the attempters'perception of community social services included any barriers to seeking help and services.Method:The participants were patients with self-harming behavior aged 15 years or above.A set of guiding questions were designed to explore the general barriers and accessibility to community social services.A voice recording was made,which was later converted into a text transcript and then preceded for content analysis with co-occurrence and similarity matrix interpretation.Two males and nine females with a history of self-harm aged between 24 and 58 years were recruited for the interviews.Result:The participants had diverse experiences and backgrounds,and attitudes toward community social services.However,there was a shared perception of the need to enhance community social services.There were four main themes and 12 sub themes identified.The main theme included the service availability,service accessibility,affordability and acceptability.For details,participants were unaware of the available types of care/social services in the community,and were unaware about the nearby social services.They also suggested extending service hours and focused services should be offered to help people with different backgrounds and needs.Actually,those with experience of service utilization had both positive and negative perspectives and they gave suggestions for service delivery,mainly extending service hours and offering focused services such as for gambling control and financial planning.In view of interaction with service providers,counseling skills and trust were highly appreciated by the participants.Conclusion:The results identified common circumstances of falling into financial hardship(gambling)and social fragmentation(divorce,poor family relationships,and poor marital relationships),which also suggested to enhance services on center location,service arrangement,and skill of caregivers.

Identification of Pathogenic Germs and Antibiotics Residues in the Raw Milk and Their Effects on Human Health

Milk is a food of great value, it provides more essential nutrient than any other natural food. The presence of pathogenic bacteria and antibiotic residues in milk can cause a real danger to consumers. Effectively, the milk consumption contaminated by bacteria can have an immediate impact which means a toxi-infection. Therefore, the presence of antibiotics residues in milk can constitute an important risk at the allergic and antibiotic resistance cases on the consumer. The present study concerning the pathogens germs identification and Antibiotic residues seeking in milk and their impact on the human health, has been realized on a total number of 80 samples of raw milk resulted from direct sale channel （dairies） throughout Blida different regions localities. The Microbiological analysis has shown only three conform samples to JORA Standards. Really, milk non-conformity results to the microbiological standards consisting on total aerobic mesophilic flora total count, total coliforms, Thermotolerant coliforms E. coli, Faecal streptococcus, Staphylococcus aureus have shown the following contamination rate： 61.25%, 93.75%, 86.25%, 55%, 93.75% and 50%. Salmonella is characterized by a total absence in all analyzed milk samples. Moreover, the antibiotics residues research by Delvotest SP make plainly visible 33 positive samples. Further, two samples of the three which were judged conform to the bacteriology standards has been found contaminated by the antibiotic residues. The analyzed milk quality can be considered as a real danger to the consumption.

截肢患者的康复

截肢的原因，在战时因火器伤截肢者占首位。在工业发达的国家，平时以交通和工伤事故居多。在美国，大型截肢（除指趾外）占人口1/3000，上、下肢截肢的比例为3：10；全国每年有35000人因伤病截肢。我国肢残病人约占人口千分之二。目前我国正在进行四化建设，工业、交通，建筑迅速发展，尽管加强预防和医疗，但截胺患者仍有增无减。
