Results There were 103 patients without deabetic retinopathy,59 patients carrying nonproliferative deabetic retinopathy and 28 patients carrying proliferative diabetic retinopathy.The above three groups had statistically different diabetic duration((121.1?93.2) vs(149.6?112.1) vs(182.2?83.5)months,P

OBJECTIVE:To observe the changes of lipid oxidation and polyol pathway metabolism of rat erythrocytes cultured in high glucose medium and intervention effect of metformin.METHODS:Rat erythrocytes were cultured in high glucose medium and the content of sorbitol in erythrocytes and the content of NO in culture medium were determined.The effect of metformin at different concentrations(2?10-5 mol?L-1,4?10-6 mol?L-1,8?10-7 mol?L-1)on the level of sorbitol and NO were studied with rat erythrocytes cultured in low glucose medium as normal control.RESULTS:Compared with normal control group,the level of sorbitol in high glucose group was increased while the content of NO was decreased(P

Objective To investigate the insulin dosage and analyze the dosage-impacting factors of intensive insulin treatment in Chinese type 2 diabetic patients.Methods Totally 1025 patients with intensive insulin treatment were included,the insulin dosage and clinical characteristics were taken down and analyzed.Results The mean insulin dosage was 39.30U/day,the insulin dosage per kg of body weight was 0.61U/Kg,among which the dosage of intermediate-acting insulin was 9.79 U/day,occupying 25.24%,while the pre-meal one was 29.51 U/day,occupying 74.76%.According to the insulin dosage per kg of body weight,patients were divided into low dosage group and high dosage one.The result showed significant difference in period of diabetes,BMI,HbA1c,and the highest weight level between the two groups.Correlation analysis showed that the average insulin dosage per kg of body weight was positively correlated with period of diabetes,HbA1c,fasting glucose level and LDL-C,while negatively correlated with BMI,fasting and postprandial C-peptide,the highest body weight level and HDL-C.Conclusions The average insulin dosage for type 2 diabetic patients is 39.30U/day,among which the dosage of intermediate-acting insulin occupies 25% while the pre-meal one occupies 75%.The insulin dosage is positively correlated with period of diabetes and HbA1c,while negatively correlated with BMI and the highest body weight level

Objective To explore the competency of community health administrators in a survey of such administrators at large in Shanghai. Methods McClelland's Competency Dictionary was used to set two benchmark positions, while the behavioral event interviewing and questionnaires were made to survey 19 community health service centers in Shanghai. Results The competency model benchmarking on the head of a medical branch consists of 6 character clusters, 11 characteristic items, 27 evaluation dimensions and 27 typical behavior descriptions. The model benchmarking on the community team leader consists of 5 character clusters, 8 characteristic items, 21 evaluation dimensions and 21 typical behavior descriptions. Conclusion Findings of the survey provide objective criteria for competence appraisal of community health administrators, and serve as reference for formulating their development plans as well.

With the increasing incidence and prevalence of male sexual dysfunction, andrologists are more and more in need of accurate and efficient tools to assess therapeutic efficacy and patients' satisfaction and to help patients achieve satisfactory treatment results. This article summarizes some of the most commonly used questionnaires for the diagnosis and assessment of the treatment of male sexual dysfunction, including International Index of Erectile Function (IIEF), Erection Hardness Score (EHS), Quality of Erection Questionnaire (QEQ), Erectile Dysfunction Inventory of Treatment Satisfaction (EDITS), Treatment Satisfaction Scale (TSS), Self-Esteem and Relationship (SEAR), Premature Ejaculation Profile (PEP), Premature Ejaculation Diagnostic Tool (PEDT), Index of Premature Ejaculation (IPE), Arabic Index of Premature Ejaculation (AIPE), Aging Male Symptoms Scale (AMS), Androgen Deficiency in the Aging Male (ADAM), and Symptomatic Inventory for Screening Late-Onset Hypogonadism in Males (SILOH), and presents an overview on their clinical application.

Insect antifreeze protein (AFP) has high antifreeze activity. Antifreeze proteins can be used in cryopreservation of biological tissues and cells. We expressed an antifreeze protein from the desert beetle Microdera punctipennis in yeast and determined the function of the protein at low temperatures. Yeast expression vector, pPIC9K-Mpafp698, was constructed and transformed into Pichia pastoris GS115. The expression of MpAFP698 was induced by methanol, and identified by tricine SDS-PAGE and Western blotting. Mpafp698 gene was inserted into the genome of the host yeast strain GS115, and correctly expressed. Hardly any yeast's own protein was secreted into the media. Cryoprotective experiments showed that MpAFP698 can significantly protect mouse liver as well as other mouse organs from cold damage compared with those in the control of Bovine serum albumin (BSA) addition. Besides, the hemolysis of blood cells protected by MpAFP698 at 4 degrees C was reduced and the survival rate of SF9 cells protected by MpAFP698 after freezing and thawing was increased compared to those of the control with BSA addition. Our results showed that MpAFP698 can be expressed in yeast, which allows a convenient purification of the MpAFP protein that has the cryoprotective effect.
