The plasma arginine vasopressin (AVP) level was measured by RIA in 19 patients with polyuria and polydipsia, and the AVP measurement was compared with indirect tests. The AVP levels were very low in 13 patients with central diabetes insipidus and normal in 6 patients with primary polydipsia. The direct assay was correspondent to the indirect criteria in 89% of the patients. We concluded that the use of AVP assay improves accuracy in the differential diagnosis of polyuria, and is important in the diagnosis of these diseases.

Objective To compare the Occurrence rate of unplanned extubation(UEX)and anastomotic leakage by two different gastric tube for gastrointestinal decompression in patients after the operation of esophageal carcinoma.Methods Three hundred and eighty patients were randomly divided into two groups,the experimental group(n=90),ballonet gastric tubes were used;the control group(n=90),general gastric tubes were used.The occurTence rate of unplanned extubation(UEX)and anastomotic leakage were investigated.Results There was a remarkable difference(P＜0.01)in the rate of UEX between the experimental group and the control group.Though no statistical difference was seen in the rate of anastomotic leakage(P＞0.05),lower incidence of anastomofic leakage was seen in the experimental group.Conclusions BalIonet gastric tube for gastrointestinal decompression in patients after the operation of esophageal carcinoma can reduce the rate of UEX,improve the nursing qualiy and also successfully reduce the rate of anastomotic leakage.

Red blood cell sorbitol contents were determined with a enzymatic method in 37 diabetics and 19 controls. The fasting blood glucose (FBG) levels and RBC sorbitol contents in the diabetics were significantly higher than that in the controls. RBC sorbitol was positively correlated to FBG, but not to the age of the patients or the type and duration of diabetes mellitus. In 9 patients whose nerve conduction velocity was measured, RBG sorbitol content was negatively correlated with motor nerve conduction velocity of median nerve (r =-0.768, P

Objective To study the clinical features of diagnosis and treatment in children with low-risk myelodysplastic syndrome(MDS) and improve the diagnosis and treatment.Methods The examinations of 17 children with low-risk MDS were analyzed.The blood concentrations of cyclosporine,one of the therapeutic drugs,were monitored and the responses to the treatments were evaluated.Results Exa-mination of full blood count showed that the reductions of 3 cell types,2 cell types and 1 cell type were 11 (64.7%)cases,5(29.4%)cases and 1(5.9%)case,respectively.Reticulocyte count showed an increase in 82.4% of the patients and normal in 3 cases.Fourteen in 17 cases were hyperplastic marrow and 3 cases were hypoplastic marrow.Among all cases,one lineage,2 lineages and 3 lineages dyspoiesis were seen in 8(47.1%),7(41.2%) and 1 (5.9%)cases,respectively.One case showed no dyspoiesis.Cytogenetics examination showed normal in 10(58.8%) cases and abnormal in 7(41.2%) cases.Fifteen (88.2%) cases had normal proportions of CD59 negative cells,while 2 cases had higher proportions.The blood concentrations of cyclosporine that were tested in 9 cases at the end of the third week were in a range of 95.3-316.5 ?g/L.The therapeutic effect of 10 cases were evaluated at the end of the third month after being treated.Eight cases achieved haematological improvement and 2 cases didn′t.The rate of improvement was 80%.Conclusions The patients of low-risk MDS are mostly school-aged children and pancytopenia is the most common sign.The combination of predisone,cyclosporine and stanozolol agents shows good effect to treat low-risk MDS.The absorption of cyclosporine is different individually,so it is significant to adjust the dosage of cyclosporine according to the concentration regularly in clinical practice.

Objective To investigate the effects of pioglitazone on angiotensin Ⅱ(AngⅡ) -induced proliferation and collagen typeⅠ expression of adventitial fibroblasts (AF). Methods The AFs were isolated from rat thoracic aorta. MTT colorimetry and flow cytometry were used to study the effects of pioglitazone on proliferation and cell cycles of AF. The expression of collagen typeⅠ regulated by pioglitazone was examined by the method of Western blot. Results Pioglitazone inhibited the proliferation of AF in a dose-dependent manner, and the most marked effect could be observed at the concentration of 10?10-6 mol/L for pioglitazone (P

Background Keratoconus is a progressive corneal thinning and protrusion disease that develop in the age of puberty,resulting in a certain extent impairment of visual function.Corneal collagen cross-linking (CXL) increases the stiffness of the cornea through the photooxidation of ultraviolet A (UVA) and riboflavin,with the aim to postpone and prevent the progression of keratoectasia.Objective This study was to evaluate the safety and efficacy of transepithelial CXL in the treatment of pediatric keratoconus.Methods Ten eyes of 9 pediatric patients with keratoconus undergoing transepithelial CXL were enrolled from February 2010 to March 2013 in Affiliated Eye Hospital of Wenzhou Medical University,with the mean age was (15± 1) years (range from 13 years to 17 years).After topical anesthesia (0.1％ tetracaine) for 15 minutes,0.5％ riboflavin was applied until it was saturated in the anterior chamber,then UVA with the intensity of 3 mW/cm2 was performed on the cornea for 30 minutes.The uncorrected distance visual acuity (UDVA),corrected distance visual acuity (CDVA),refractive error,topography,corneal thinnest thickness were measured 7 days,1 month,3 months,6 months and 1 year after operation.Endothelium cell density (ECD) was measured 7 days afier operative.Results The mean corneal reepithelization time was (1.4±0.8) days.The UDVA and CDVA were significantly improved from preoperative 1.02±0.16 and 0.34±0.20 to postoperative 0.77±0.18 and 0.25 ±0.15,respectively (t =4.251,3.750;both at P＜0.05).The refractive sphere and spherical equivalent significantly changed from preoperative (-7.15±3.00)D and (-9.26±3.23)D to postoperative (-5.28±2.05) D and (-7.05±2.08) D 1 year,respectively (t =-2.515,-2.597;both at P＜0.05).Maximum Kvalue (Kmax) was significantly decreased from preoperative (64.1 ± 11.9) D to postoperative (61.8 ± 10.4) D (t =2.304,P＜0.05).The refractive cylinder,corneal thinnest thickness and ECD showed no significant differences between preoperation and postoperation (t =-1.331,0.328,1.205;all at P＞0.05).Stromal opacity was observed in 2 eyes 3 months and 6 months after operation,respectively.Conclusions Transepithelial CXL is safe and effective in prolonging or halting progression in adolescent keratoconus.
