Objective To explore the curative effect of acyclovir combined with pidotimod in treatment of adult varicella.Methods 80 adult patients with varicella in our hospital were randomly divided into two groups.40 cases in group A were intravenously injected acyclovir.40 cases in group B were intravenously injected acyclovir combined with oral pidotimod.The time of herpes blisters drying and completely crusted were observed in two groups.Results The time of herpes blisters drying and completely crusted of B group was shorter than A group.And the differences were statistically significant(P ＜0.01).Conclusion Acyclovir combined with pidotimod in treatment of adult varicella can significantly shorten the healing time,and show better curative effect than single use of acyclovir.

The level of serum fibroblast growth factor-21 (FGF-21) in patients with type 2 diabetes mellitus complicated with non-alcoholic fatty liver disease (NAFLD) was determined by ELISA.The results showed that serum FGF-21 level in these patients was higher than that in type 2 diabetic patients [(266.55 ± 21.24 vs 220.32 ± 22.68) ng/L,P＜ 0.01].Serum FGF-21 levels in both groups were significantly higher than that in normal control group [(173.52 ± 16.18) ng/L,P＜0.01].Serum FGF-21 level was positively correlated with waist circumference,blood glucose,and triglyceride.FGF-21 may contribute to the development of NAFLD in the patients with type 2 diabetes mellitus.

The changes of serum apelin in patients with metabolic syndrome were investigated. The level of fasting serum apelin was determined by ELISA assay.The level of serum apelin was raised obviously in patients with metabolic syndrome(MS).Moreover,the level of serum apelin in patients with type 2 diabetes mellitus was higher than those in cases of MS with impaired glucose regulation and the group of subjects with overweight/obesity [ (475.8±37.3 vs 451.5±54.3 and 430.3±52.1 ) ng/L,P＜0.01 ].In a multiple step-wise regression analysis,In homeostasis model assessment of insulin resistance ( HOMA-IR),body mass index,and total cholesterol were independent factors of apelin.The increased serum apelin was closely related to metabolic abnormalities in metabolic syndrome.The increased insulin resistance might cause the raised level of serum apelin in patients with MS.

Objective To investigate the clinical features and effective treatment of patients with severe type A H1N1 flu in Wenzhou. Methods The clinical data of 42 hospitalized patients with severe type A H1N1 flu were analyzed and the clinical features were summarized. Results A total of 42 patients with severe type A H1N1 flu all began with fever and cough. The symptoms of expectoration, pharyngalgia, chilly accounted for 92. 9%, 90. 5% and 42. 9%, respectively. The peripheral leucocyte counts were normal or reduced. C-reactive protein and erythrocyte sedimentation rate levels both increased in 30 patients (71.4%). About 95.2% (40/42) patients had changes of pulmonary imaging. All of the patients were treated with oseltamivir and effective antibiotic drugs as well as symptomatic management. No patients was treated with glucocorticoid. The patients with underlying diseases were given proper treatment. Three cases were treated with antifungal therapy and 3 pregnant patients were timely terminated of pregnancy. Conclusions Severe type A H1N1 flu progresses rapidly and the lower respiratory tract is involved soon after onset. Therefore, the patient should be diagnosed early and treated promptly after presenting fever, which will lead to good prognosis.

Objective To study the effects of Apelin on glucose toxicity and islet cells PDX-1 protein expression.Methods The islet β cell line NIT-1 cells were incubated in the medium containing different glucose concentrations(normal glucose concentration group 5.6 mmol/L,high glucose concentration group 16.7 mmol/L,extremely high glucose concentration group 33.3 mmol/L) and +/-Apelin-36 respectively for 3 d.Then the basic insulin secretion amount of islet cells and their secretion amount after glucose stimulation were detected.The intracellular insulin content and the PDX-1 protein and mRNA expression were detected.Results Compared with the normal glucose group,the basic insulin secretion,secretion after stimulation and intracellular insulin in the high glucose group and extremely high glucose group were significantly decreased and PDX-1 protein expression was declined(P＜ 0.05);compared with non-adding Apelin group,the basic insulin secretion,secretion after stimulation and intracellular insulin in the adding Apelin high glucose group and extremely high glucose group were significantly decreased and PDX-1 protein expression was decreased(P＜0.05);the insulin level in islet cells of 6 groups was positively correlated with PDX-1 protein expression and had no correlation with PDX-1 mRNA expression.Conclusion Apelin may participate in the glucose toxic effect by decreasing PDX-1 protein expression,causes the decrease of insulin secretion,thus plays a role in the pathogenesis of diabetes.

OBJECTIVE To observe the effect of natrin from Naja naja atra(Chinese cobra)on intracellular free calcium overload,and to discuss the protective effect and the possible mechanism of natrin on myocardium calcium(Ca2+)and potassium(K+)ion channels in the primary cardiomyocytes of SD neonatal rats. METHODS The primary cardiomyocytes of SD neonatal rats were used,which were respectively pretreated with natrin 5,25 and 125 mg · L-1 for 24 h before injury was induced by H2O2 0.3 mmol · L- 1. The dynamic variation of intracellular calcium was monitored by laser confocal microscopy using Fluo-3 as Ca2+fluorescence probe. Additionally,the cardio myocytes of neonatal rats were pretreated for 24 h using different concentrations of natrin 5,25,125 mg · L-1 and verapamil 5 nmol · L-1,followed by exposure to H2O2 0.3 mmol · L-1 for 15 min. Then,the mRNA expressions of calcium channels subunits Cav1.2,Calm,RyR2 and potassium channel Kir6.2 were analyzed by FQ-PCR method. RESULTS Laser confocal microscopy revealed that H2O2 obviously caused calcium overload in cardiomyocytes, giving rise to 49.37% fluorescence increase in intracellular calcium compared with the control group(P<0.01). However,natrin 5,25 and 125 mg·L-1 resulted in 27.52%, 12.71% and 5.15% fluorescence increase in intracellular calcium,respectively,compared with the control group(P<0.01). Moreover, the PCR results showed that the mRNA expressions of Cav1.2, Calm and RyR2 in the myocardial cells treated with H2O2 were increased 2.78,2.26,and 5.34 times as compared with the control group,while Kir6.2 displayed a 1.79-fold expression level(P<0.01). By contrast, the combination of natrin and verapamil significantly decreased the mRNA expression of Cav1.2,Calm and RyR2,compared to the H2O2-treated group(P<0.01). Meanwhile,the expression of Kir6.2 was considerably higher than that of the H2O2-treated group(P<0.05). CONCLUSION Natrin can reduce the intracellular calcium overload of cardiomyocytes induced by H2O2 and shows a protective effect against oxidative damage for cardiomyocytes. The possible mechanism is that natrin can decrease the mRNA expression of Cav1.2,Calm,RyR2 and increase the expression of Kir6.2 of the H2O2-induced cardiomyocytes.

Objective To study the prevalence and related risk factors of type 2 diabetes with coronary heart disease(CHD) and cerebral infarction after long-term treatment.Methods Two hundred and eighty-five patients with type 2 diabetes who had a hospitalization interval for four to twelve years between the first and second hospital stays were included in group A.Among them,85 patients (about 4 to 7 years) with a hospitalization interval about 5 years (4 to 7 years) between the first and second hospital stays(group B).100 patients with a hospitalization interval about 10 years (8 to 12 years) between the first and second hospital stays(group C).Blood pressure,blood glucose,HbA1c,blood lipids,myocardial enzymology,electrocardiogram,coronary angiography,cranial CT or MRI were tecorded.The prevalence of CHD and cerebral infarction were compare,regression analysis was conducted between coronary heart disease,cerebral infarction and the risk factors.Results DBP,FBG,PBG2h,TC,LDL-C of the second hospitalization were significantly lower than those of the first hospitalization.The morbidity of CHD and cerebral infarction increased along with the extension of the course.The morbidity of cerebral infarction in CHD patients were significantly higher than those in non-CHD patients with the interval about 10 years.Logistic regression analysis proved that age was risk factor and HDL-C was protective factor of CHD,SBP,FBG were risk factors of cerebral infarction.Conclusion The morbidity of CHD and cerebral infarction increased along with the extension of the course and there were significantly relationship between CHD and cerebral infarction in T2DM patients after about 10 years treatment.

To report a case of Noonan-like syndrome with loose anagen hair, and to detect gene mutations in the family. A 3-year-old female patient presented with a special facial appearance, short stature, deep palmar and plantar creases, and dark skin. The scalp hair was sparse and thin, dermoscopy showed black spot sign, single-hair follicular units, hair shafts varying in the diameter, upright hair and new vellus hair, and constriction of hair shafts and nodular hair were occasionally observed. Peripheral blood samples were collected from the proband and her parents, and the genomic DNA was extracted for whole-exome sequencing. A heterozygous missense mutation c.4A>G was identified in exon 2 of the SHOC2 gene in the proband, resulting in the substitution of serine by glycine at amino acid position 2 (p.S2G) . The mutation was not identified in either of her parents. Combined with the clinical phenotype and gene mutation, the diagnosis of Noonan-like syndrome with loose anagen hair was confirmed.

ObjectiveTo observe the effects of electroacupuncture at Zhongwan （CV12） on gastric nociceptive response induced by gastric acid stimulation and explore the underlying mechanisms associated with nuclei of the medullary viscerosensory and visceral motor neurons. MethodsTwenty SD rats were given intragastric administration of 0.5 mol/L diluted hydrochloric acid （0.5 ml/100 g） to induce gastric nociceptive response induction. Eight rats were randomly selected to record the gastric slow wave （GSW） area under the curve， and extracellular discharge frequency of neurons in the nucleus of the solitary tract （NTS） and dorsal motor nucleus of the vagus nerve （DMV） before intragastric administration and at 1， 5， 10， 15， 20， 25， 30， 35， 40， 45， 50， 55， and 60 minutes after intragastric administration. The remaining 12 rats received electroacupuncture intervention at Zhongwan within 5 to 25 minutes after intragastric administration of diluted hydrochloric acid， with a duration of one minute. The GSW area under the curve and extracellular discharge frequency of NTS and DMV neurons were compared between the 1-minute intervals before and after electroacupuncture intervention. ResultsCompared to the baseline before intragastric administration， the area under the curve of GSW significantly increased at 1， 5， 10， 15， 20， and 25 minutes after intragastric administration， and the extracellular discharge frequency of excitatory neurons in the NTS （accounting for 90%， 57/63） significantly increased at 1， 5， 10， 15， 20， 25， 30， 35， and 40 minutes， both reaching peak values at 1 minute after intragastric administration （P＜0.01 or P＜0.05）. The extracellular discharge frequency of inhibitory neurons in the DMV （accounting for 91%， 20/22） showed a non-significant increase at 1 minute after intragastric administration （P＞0.05）， but significantly decreased at other timepoints （P＜0.05）. Compared to the baseline before electroacupuncture intervention， the GSW area under the curve and the extracellular discharge frequency of excitatory neurons in the NTS significantly decreased （P＜0.05）， while the extracellular discharge frequency of inhibitory neurons in the DMV showed no significant difference （P＞0.05）. ConclusionElectroacupuncture at Zhongwan can improve gastric nociceptive response induced by gastric acid stimulation， possibly by reducing the transmission of visceral sensation and decreasing the excitability of NTS neurons in the medulla.
