Objective To study the diagnostic utility of hemoglobin electrophoresis in neonatal cord blood screening for thalassemia. Methods Between January 2012 and December 2013, 14032 core blood samples which were from different 21 Women and Children Hospitals in Guangdong were performed for the neonatal screening with hemoglobin electrophoresis. The positive samples of hemoglobin electrophoresis were recalled for genetic testing. Results Out of 1445 (11.07%) positive samples of hemoglobin electrophoresis , 1075 (54.08%) cases were suspected for α-thalassemia, 478 (3.41%) cases were suspected for β-thalassemia, 127 (0.91%) cases were suspected for abnormal hemoglobin. With the genetic testing, 967 cases were diagnosed as α-thalassemia, 404 cases were diagnosed asβ-thalassemia. The coincidence rate ofα-thalassemia andβ-thalassemia were 89.95%and 82.96%, respectively. Besides, 124 cases were diagnosed as abnormal hemoglobin, including 38 cases of Hb E, 28 cases of Hb Q, 21 cases of Hb D, 19 cases of Hb New York, 13 cases of Hb J, and 5 cases of Hb J. Conclusion Hemoglobin electrophoresis was definitely helpful in the neonatal cord blood screening for thalassemia and abnormal hemoglobin.

Objective To establish a diabetic rat model of hindlimb ischemia, and provide a test method for dia-betic limb ischemia and diabetic foot study.Methods Twenty-five Wistar rats were divided into three groups:the model group and control group ( n=10) , and sham operated group ( n=5) .The rats of model group were induced by intraperito-neal injection of streptozotocin ( STZ, 60 mg/kg) , with the blood glucose level over 16.8 mmol/L, while the rats of control group were injected with normal saline.All the rats had the left femoral artery and its branches ligated, and then Doppler scan blood flow analysis was performed for the two hind limbs after operation at different time points.In the meantime, the changes of body weight and blood glucose were observed.The animals were sacrificed at 21days after operation.HE stai-ning was used to observe the pathological changes of gastrocnemius and femoral arteries.Capillary density and intima hyper-plasia were examined using immunostaining for CD31 and a-SMA.Results Blood glucose of the model group rats was sig-nificantly increased as well as the quantity of urine and feces,and associated with weight loss, which were maintained for more than 21 days.The blood flow of control rats was markedly decreased immediatly after operation, reached to the lowest point after surgery, and recovered from 7 -14 days after operation.In contrast to the control group, the model group showed a marked reduction in blood flow in the ischemic hind limb.Pathological examination revealed remarkable vascular atrophy and a significantly reduced number of vessels per high power field in the gastrocnemius muscle of model group rats with respect to the control group, and the femoral arteries of model rats were more narrowed than that of the control rats. Conclusions In this study, an effective, convenient diabetic rat model of hindlimb ischemia is successfully established which will facilitate the studies of drug intervention for diabetic limb ischemia and diabetic foot in the future.

Objective To detect the expression of Raf kinase inhibitor protein (RKIP) and NF-κB in renal tissue of diabetic kidney disease (DKD) rats model,and to investigate the effect of rituximab (RTX) on the expression of RKIP in the renal tissue of DKD rats. Methods SD rats were randomly divided into normal group (N),DKD model group (M) and RTX treatment group (D).Blood glucose and 24-hour urine protein of rats were determined in three groups.RKIP protein and NF-κB protein were determined by immunohistochemistry staining. RKIP protein expression was detected by Western blotting. Results Compared with N group,blood glucose,24-hour urine protein and NF-κB expression in M group increased significantly (all P＜ 0.01),the expression of RKIP in M group decreased significantly (P＜0.05).Compared with M group,the expression of RKIP increased significantly in D group (P＜0.05),and 24-hour urine protein and NF-κB expression decreased in D group (all P＜0.05).NF-κB protein expression was negatively correlated with RKIP expression in M group. Conclusions The NF-κB pathway regulated by RKIP plays an important role in the development and pathogenesis of diabetic nephropathy.Rituximab may have a role in treatment of DKD.

Objective To investigate the role of psychotherapy plays in the treatment of vitiligo.Methods Psychological health questionnaire(SCL-90)was used in the study to evaluate the psychological well being of 120 vitiligo patients.66 subjects suffering from psychological problems were divided randomly into groups Ⅰand Ⅱ while 54 subjects free of psychological problems randomly into groups Ⅲ and Ⅳ.Psychotherapy was applied together with drug and phototherapy to those subjects from groups Ⅰ and Ⅲ while groups Ⅱ and Ⅳ having no psychotherapy accompanied.After 3 months of treatment,evaluation was done on the treatment effect with psychological testing once again.The correlation between the improvement of psychological conditions of the subjects and the lesion development was then evaluated by"P"value of the four groups.Results Significant difference was achieved between group Ⅰ and group I1I(P＜0.05).There was no significant difference between groupsⅢand IV(P＞0.05).There was significant difference between groups Ⅰ and Ⅱ.There was no significant difference between groups Ⅱ and Ⅳ.Conclusions The psychotherapy is helpful in improving the early treatment effect and quality of life in vitiligo patients.
