To investigate the DNA typing of Trichophyton mentagrophytes,and to find the relation- ship of DNA type with morphology,teleomorph type,the geographic origin and the sites of infection. DNA extraction was carried out by using benzyl chloride and random amplification of polymorphic DNA (RAPD)assay was employed for DNA typing of 42 strains of T.mentagrophytes isolated from clinical specimens and some other dermatophytes,also 8 preserved strains of Arthroderma.Results:(1)Forty two isolates of T.mentagrophytes can be classified into 3 main types,and the intratype polymorphism has been revealed with some primers.(2)There is no simple relationship between DNA type and mor- phology,but the DNA types are closely related to the geographic origin,and the isolates from different sites of infection have their own genotype characteristics.(3)DNA patterns of Arthroderma benhamiae and A.vanbreuseghemii are distinctly different,while 42 clinical isolates of T.rnentagrophytes share sim- ilar pattern with A.vanbreuseghemii.The clinical isolates of T.mentagrophytes can be divided into 3 types by RAPD,and its DNA type has certain relationship with morphology,teleomorph type,the geo- graphic origin and ttie sites of infection.RAPD provides an useful tool for the pathogenic diagnosis and epidemiology study to investigate the source of infection,and geographic distribution of strains.

Objective To investigate the effects of melatonin on oxidative stress and metabolisms of glucose and lipid of diabetic patients.Methods By means of random,single-blind,placebo-parallel control clinical trial,91 of diabetic patients were randomly divided into melatonin group and placebo group.The parameters of Glutathione Peroxidase (GSH-Px),Superoxide Dismutase(SOD)and Malondialdehyde(MDA),as well as the profiles of glycemia and lipidemia were observed before and after 8 weeks treatments,respectively.Results Before treatment,both the serum levels of GSH-Px and SOD of diabetic patients were decreased significantly,whereas the serum level of MDA increased significantly.After 8 weeks consecutive melatonin treatment,the serum levels of GSH-Px and SOD increased significantly,whereas the serum level of MDA decreased significantly compared with pre-treatment in the melatonin group.There were no significant variations of serum levels of GSH,SOD and MDA observed before and after treatment in the placebo group.There were significan benefit on FBG and HbA1c after 8 weeks treatment compared with pre-treatment.The other profile of glycemia and lipidemia such as PBG,TG,TC,LDL-C and HDL-C hed no significant variations compared with pre-treatment.There were no significant variations of the profiles of glycemia and lipidemia compared with pre-treatment in the placebo group.Conclusion Melatonin significantly inhibits oxidative stress provoked by hyperglycemia and has beneficial effects on the glucose homeostasis of diabetic patients.

Objective To study the effects of preterm birth, infection, pathological jaundice and asphyxia on neonatal thyroid function. Methods From April 2012 to April 2014,neonates within 7 days after birth admitted to the neonatal department of our hospital were recruited. The neonates with one or more of the 4 aforementioned conditions were assigned to the observation group; the full-term newborns without any diseases to the control group. 2 ml of venous blood from each patient was collected 5-7 days after birth to determine the levels of serum free iodine thyroid original glycine ( FT3 ) , free thyroxine ( FT4 ) and thyroid stimulating hormone ( TSH ) . The thyroid function of newborns in the observation group were re-examined after recovery, and compared among different groups and conditions. Results A total of 220 newborns were recruited in the observation group and 34 in the control group. FT3 in the observation group was significantly lower than the control group ( P＜0. 05 ) . As for FT4 and TSH, no statistically significant differences existed between the two groups ( p＞0. 05 ) . FT3 and FT4 in neonates with severe infection were significantly lower than mild infection ( P＜0. 05 ) . FT3 in the preterm group with gestational age ( GA ) ≤32 weeks was significantly lower than GA＞32 weeks, and FT3 in the jaundice group, serum bilirubin level ≥ 342 mol/L group significantly lower than ＜342 mol/L group (P＜0. 05) . In the observation group, the re-examined FT3 concentration was significantly higher (P＜0. 05) than the result tested 5-7 days after birth while FT4 and TSH didn′t show significant differences. And no significant differences existed between the observation group and the control group in re-examined thyroid functions ( P＞0. 05 ) . The multivariate analysis showed that GA, pathological jaundice, infection and asphyxia were associated with FT3 concentration 5-7 days after birth (P＜0. 05), while the delivery method and gender not (P＞0. 05). Conclusions The main effect of preterm birth, infection, pathological jaundice and asphyxia on thyroid function was to decrease FT3 temporarily. Severe infection might decrease FT4 temporarily. However, the thyroid function would return to normal with recovery.

Objective To observe the therapeutic effects of balloon dilatation with ice water and room temperature water on cricopharyngeal achalasia after brainstem stroke.Methods Forty dysphagic patients with cricopharyngeal achalasia after brainstem stroke were recruited.Twenty patients assigned to experimental group were treated by balloon dilatation with ice water and low frequency elecrtrical stimulation.Twenty patients assigned to control group were treated by balloon dilatation with room temperature water and low frequency electrical stimulation.Results After treatment,36 out of the 40 patients of the two groups could eat pasty food independently without choking.Videofluoroscopic swallowing study (VFSS) showed that the cricopharyngeal sphincter relaxed and the foods passed successfully when swallowing bolus,and no aspiration happened.In comparison,the level of cricopharyngeal opening,the number of patients with nasogastric tube remained and eating normally,and the scores of functional oral intake scale (FOIS) between the two groups showed no significant difference (P ＞ 0.05).The average treatment sessions,average hospitalization days and average treatment cost in treatment group were significantly less than those in the control group(P ＜0.05).Conclusion Cricopharyngeal achalasia can be treated effectively by balloon dilatation with ice water or with room temperature water combined with low frequency electrical stimulation,but treatment course of balloon dilatation with ice water were significantly shorter than that of balloon dilatation with room temperature water.
