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 observe the effect of short-term treatment with metfbrmin on psychological distress and metabolic feature in patients with polycystic ovary syndrome(PCOS).Methods Ninety women were diagnosed as cases of PCOS based on the 2003 Rotterdam criteria.These patients were divided into three groups:group A,consisted of 26 subjects treated with mefformin only; group B,36 cases treated with metformin plus Dane-35 ; and group C,28 cases treated with placebo and Dane-35.The treatment was carried out for 3 months.Clinical and metabolic parameters were observed.The psychological distress was evaluated by the hospital anxiety and depression scale(HAD scale).Results Compared with group C,patients in group A and B showed significantly lower body mass index(BMI),waist circumference (WC),waist-hip ratio (WHR),serum fasting insulin,homeostasis model assessment for insulin resistance (HOMA-IR),total cholesterol (TC),triglyceride (TG),low density lipoproteincholesterol(LDL-C) levels as well as anxiety and depression scores,but higher high density lipoprotein-cholesterol (HDL-C) levels (all P＜0.05).Compared with group A,patients in Group B had significantly higher WC,WHR,and LDL-C levels(all P＜O.05).No significant differences in BMI,TG,HDL-C,anxiety and depression scores were found between group A and B (all P＞0.05).In group A,a positive correlation was found between the changes of metabolic feature (BMI,WHR,and HOMA-IR) and the changes of anxiety and depression scores (all P ＜0.05).Conclusion Short-term treatment with metformin will benefit patients with polycystic ovary syndrome,regarding psychological distress and metabolic features.

Objective To investigate the effect of Rho/Rho-kinase inhibitor fasudil combined with conventional vasodilating agents nitroglycerin in treatment of unstable angina pectoris.Methods Twenty patients[mean age (61 ± 11) years old]with unstable angina pectoris (angiospasm in the left anterior descending coronary artery) were selected and divided into fasudil group and control group with 10 cases each by random digits table.All the patients were examined by the acetylcholine stress test.Coronary diameter at the spasm site was measured and compared at baseline and after the administration of nitroglycerin in the following order: intracoronary nitroglycerin (300 g), intravenous fasudil (30 mg, fasudil group) or saline (control group), and again nitroglycerin (300 g) during coronary angiography.Results There was no significant difference in coronary diameter at the first nitroglycerin administration between fasudil group and control group[(38.2 ± 23.6)% vs.(42.6 ± 17.2)% ,P ＞0.05].Coronary diameter at intravenous fasudil and again nitroglycerin administration in fasudil group was expanded, and there was significant difference compared with that of the first nitroglycerin administration[(2.48 ±0.79), (2.51 ± 0.78 ) mm vs.( 2.11 ± 0.62 ) mm](P ＜ 0.01 ), but there was no significant difference in control group (P ＞ 0.05).There was no adverse effect in two groups,and blood pressure and heart rate was stable in fasudil group.Conclusions Fasudil further dilates the site of coronary spasm, which had already been treated with nitroglycerin in patients with vasospastic angina.These findings support and extend the previous results that shows the feasibility of employing fasudil as a novel therapeutic approach for coronary spasm.

BACKGROUND:Compared with the conventional composite resin, the 3M Z350 nano-resin has good wear
resistance, physical mechanical properties, and polishing, and exerts a lower irritation to the dental pulp. Besides fil ing materials, a reliable tooth-prosthesis bonding interface is necessary for resin bonded repairs.
OBJECTIVE:To compare the clinical effects of self-etch bonding Adper Easy One and total-etch bonding Single Bond 2 on nano-resin bonding restoration of the anterior teeth.
METHODS:120 anterior teeth with vital pulp, which had defects at the incisal ends and were to be restored with nano resins, were divided into two groups randomly. Two kinds of adhesives, self-etch adhesive and total-etch adhesive, combined with nano-resin were used to restore the teeth. The patients were re-examined immediately, 6 months, 1 year and 2 years after the treatment. The fil ings, teeth and pulps of patients were examined,
including whether the prosthesis and tooth color were coordinated, whether the gap between the prosthesis and the teeth were sealed, whether the surface of the prosthesis was intact with no loose, whether the prosthesis and teeth had no staining and secondary caries, whether the condition of the tooth pulp had hot or cold
stimulation-induced pain.
RESULTS AND CONCLUSION:No significant difference in the fil ing effects was found between the two groups when the patients were re-examined immediately, 6 months and 1 year after the treatment (P>0.05). The pulp
lesions of the self-etching group were fewer than those of the total-etch group 2 years after the treatment (P<0.05). Self-etching group had 1, 6, 0, 2 cases and total-etch group had 0, 2, 1, 2 cases in uncoordinated color, edge seal,
incomplete restoration and secondary caries, respectively. No statistical y significant differences were found in these four aspects between the two groups (P>0.05). The 2-year fol ow up showed a low incidence of pulp lesions and satisfactory clinical performance after 3M Z350 nano-resin working with self-etching bonding system in the nano-resin fil ing of
anterior teeth with vital pulp.
