Metallothionein is a sulfhydryl-rich,and chelating a large number of metal ions,which is widely found in biological world.It is very highlighted that MT had the same physical and chemical features from different origins.Plenty of research data indicated that MTs contain 20 free sulfhydryl genes,as well as their sulfhydryl clusters,It is a multifunctional protein in health.Many experiments demonstrate that MTs may be a novel target of original new drugs because they play a role in regulating and controlling the organ fibrosis and tumor.

Objective To evaluate the effects of soybean protein and animal protein on renal function of patients with diabetic nephropathy.Methods In this Meta-analysis,literatures on the effects of soybean protein and animal protein on renal function of patients with diabetic nephropathy published during January 1980 and November 2011 were reviewed and analyzed quantitatively and synthetically by using Metaanalysis RevMan 5.0 software.Results Five case-control studies met the inclusive criteria and entered into random effect model.In comparison with animal protein,soybean protein significantly improved endogenous creatinine clearance rate (weight mean difference (WMD) =-11.51,95％ confidence interval (CI)-16.37 to 6.65),proteinuria (WMD =-0.96,95％ CI-1.36 to-0.58),urine creatinine (WMD =-1.11,95％ CI-1.91 to-0.30),glomerular filtration rate (WMD =0.28,95％ CI-0.12 to 0.68),serum urea nitrogen (WMD =-0.20,95％ CI-0.60 to 0.19) and serum creatinine (WMD =-0.22,95％ CI-0.54 to 0.10).Conclusions Soy protein seems to have potential to improve urine creatinine clearance,urine creatinine,proteinuria and serum urea nitrogen.However,animal protein may contribute to increased glomerular filtration rate.

Objective:To investigate the effects of Jianpijiedutang combined with Kangfuxin Liquid in the treatment of recurrent oral ulcer(ROU).Methods:80 patients with ROU were divided into 2 groups(n=40).The patients in control group were treated with Kangfuxin Liquid local spray,those in the test group were treated with Jianpijiedutang combined with Kangfuxin Liquid spray.The patients were followed up for 24 weeks.The effects were evaluated according to the trial standard of Chinese Stomatological Association.Results:The interval of ROU increased and ulcer number decreased in the 2 groups during the observation period,the test group showed more effective outcome than the control group(P<0.05).In the treatment group ROU interval increased more than in the control group(P<0.01),and ROU ulcer number decreased more(P<0.01).Conclusion:The Jianpijiedutang combined with Kangfuxin Liquid spray is more effective than the latter used only.

Objective To explore the clinical characteristics and treatment of paroxysmal supraventricular tachycardia (PSVT) in children. Methods The clinical data of 67 children with PSVT were analyzed retrospectively, and the therapeutic effects of different treatments were compared. Results The clinical manifestations of infants were paleness, shortness of breath, irritability and sweating, and children showed chest tightness, palpitations, abdominal discomfort and fatigue. The curative effect of electric cardioversion, transesophageal atrial pacing, physical therapy, and drug therapy was statistically different (P<0.05), The different cardioversion rates of them were observed for the treatment of paroxysmal supraventricular tachycardia. The cardioversion rate of transesophageal atrial pacing, was the highest, and the rate of physical therapy was the lowest. There was no significant difference in the cardioversion rate between propafenone, digoxin and amiodarone. Conclusion The clinical manifestations of PSVT in infants are atypical and easily to be ignored. There are many methods for treatment of PSVT. The vagus nerve can be stimulated first, and, if no response, either drugs or electric cardioversion and transesophageal atrial pacing can be used. The cardioversion rate of transesophageal atrial pacing is higher. The drug effectiveness for the treatment of PSVT depends on many factors, and our choice of medication varies from person to person.

Objective To compare the duration of neuromuscular blockade in laparoscopic and open surgical approaches following a single bolus dose of rocuronium or cisatracurium.Methods One hundred female patients underwent either laparoscopic or open gynaecological surgery were randomly and equally divided into OR group (rocuronium administered in open surgery),OC group (cisatracurium administered in open surgery),LR group (rocuronium administered in laparoscopic surgery) and LC group (cisatracurium administered in laparoscopic surgery).Anaesthesia was induced with sufentanil of 0.5 μg/kg and propofol of 2 mg/kg,and neuromuscular blockade was induced with rocuronium of 0.9 mg/kg or cisatracurium of 0.15 mg/kg,intravenously.Then adductor pollicis trainof-four responses following ulnar nerve stimulation were monitored with mechanomyography.We recorded the duration of the first twitch (T1) occurrence after the injection of rocuronium or cisatracurium,and the duration from T1 recovered to 5 ％ and 25 ％ of baseline.Results The mean time from the end of injection of rocuronium until spontaneous recovery to T1,and to recovery to 5％and 25％ of baseline,was significantly prolonged in LR group [(44.8 ± 10.7) min,(52.8 ± 11.2) min and (62.6 ± 13.5) min] compared with OR group [(36.2 ± 4.0) min,(41.8 ± 6.8) min and (49.5 ±7.5) min] (P all＜0.05) On the other hand,there was no significant difference on the duration of neuromuscular blockade between LC group and OC group.Conclusions Neuromuscular blockade may be prolonged following a single bolus dose of rocuronium given during laparoscopic procedures,which should be on the alert,and assess neuromuscular function to ensure safe recovery.

Objective To observe the effect of Wnt/β-catenin pathway on proliferation of human umbilical vein endothelial cell (HUVEC) using the glycogen synthase kinase 3β (GSK-3β)-targeting RNAi recombinant adenovirus vector. Methods Homologous recombination and cloning techniques were used to construct RNAi recombinant adenoviral expressive vectors specific to GSK-3β. Then, the adenovirus plasmids was transfected into HEK 293A cells to produce adenovirus and amplify the adenoviral stock. Plaque forming assay was used to titer the adenoviral stock. The GSK-3β and β-catenin protein expressions were detected by Western blot and immunohistochemistry. The proliferation of HUVEC was detected with MTr assay. Results The RNAi adenovirus vectors specific to GSK-3β were successfully produced with high titer. The expression of GSK-3β protein in HUVEC could be down-regulated efficiently by the RNAi adenovirus, along with increased β-catenin protein expression. The proliferation of HUVEC was significantly increased (P < 0.05 or P < 0.01) after infected with GSK-3β RNAi recombinant adenovirus for 3, 5, 7 days. Conclusion RNAi adenovirus is an important tool that can inhibit the expression of GSK-3β efficiently, along with increased β-catenin protein expression. Up-regulating of the Wnt/β-catenin pathway might play an important role in the proliferation of HUVEC.

Objective To look for an appropriate dietary pattern of early nutritional intervention, which does not only meet the need of catch-up growth but also avoids or reduces the incidence of insulin resistance (IR) in adulthood of rats born with intrauterine growth retardation (IUGR). Methods The model of IUGR in rats was established by maternal nutrition restriction. Sixty newborn female rats with IUGR were randomly divided into 5 groups: (1) IUGR control group fed with common diet. (2) IUGR high-carbohydrate diet group. (3) IUGR high-fat diet group. (4) IUGR high-protein diet group. (5) IUGR low-protein diet group. The IUGR newborn rats were breast-fed for 3 weeks, while the mother rats were fed with the above different diets with the same caloric amount. Twelve normal newborn female rats served as a normal control group and were fed with common diet. All newborn rats were fed routine diet starting from the 4th week of experiment. The body weight, perirenal fat weight and the serum leptin, blood glucose, insulin concentration were measured and the insulin sensitive index (ISI) were calculated at the 4th week and the 12th week of life. Results The IUGR rats fed with high-protein diet showed a catch-up growth without the increase of perirenal fat at the 4th week, a normal level of perirenal fat, leptin and ISI at the 12th week compared with the normal control group, and did not show IR. The groups fed with high carbohydrate diet and high fat diet also showed a catch-up growth, but did the same as the IUGR control group in other aspects, they all showed increased perirenal fat, higher levels of leptin, lower ISI and IR at adulthood. The group fed with low protein diet did not show IR, but kept a small body size with increased perirenal fats. The serum leptin level of rats was positively correlated to body weight at the 4th week of life and was positively correlated to the weight of perirenal fat and negatively correlated to ISI at the 12th week of life. Conclusion High protein diet is an appropriate early nutritional intervention for rats with IUGR. The serum leptin level at the 12th week of life seems to be an index of IR in adult rats with IUGR.

Objectives To explore the clinical features and pathogenesis of Kawasaki disease (KD) combined with sterile pyuria. Methods A total of 420 patients diagnosed of KD were recruited and divided into pyuria group ( 95 patients) and control group ( 325 patients) according to urine routine examination on admission. The clinical data between the two groups were compared. Results There was no difference in gender, age, and the incidence of atypical KD (P all?>?0 . 05 ). The levels of C-reactive protein, D-dimer concentrations, fibrinogen degradation products, alanine aminotransferase, aspartate aminotransferase, and urine retinol binding protein were higher in pyuria group than those in control group (all P>?0 . 05 ). No difference was found in the duration of fever before admission between two groups (P>?0 . 05 ). However, pyuria group had longer duration of fever after treatment with immunoglobulin (P?0.05). Conclusion The morbidity of sterile pyuria in KD patients was 22 . 6%. KD patients with sterile pyuria have more intense inlfammatory response, markedly high coagulation condition, and mild or subclinical renal damage.

Objective To improve the knowledge of paediatric pulmonary arterial hypertension(PAH) and to elevate the level of early diagnosis and treatment.Methods The clinical data of 45 PAH patients admitted in Shanghai Children's Hospital from Jan.2006 to Dec.2012 were reviewed,including clinical manifestation,laboratory examination,diagnosis,treatment and prognosis.Results Of the 45 PAH patients,21 cases (46.7％) were male and 24 cases (53.3 ％) were female,with an average age of 2.5 years old.Among them idiopathic PAH was in 24 cases (53.3 ％) and secondary PAH was in 21 cases [including interstitial lung disease in 4 cases,upper airway obstruction in 3 cases,systemic lupus erythematosus in 3 cases,hepatic disease in 3 cases,including hepatic hemangioma 1 case,liver cirrhosis portal hypertension 1 case and autoimmune hepatic sarcoidosis 1 case,tachycardia induced cardiomyopathy in 2 cases,extensive pulmonary small artery stenosis in 2 cases,human immunodeficiency virus (HIV) infection in 1 case,hypothyroidism in 1 case,and familial PAH in 2 cases].Main clinical manifestations were anhelation after exercise (71.1％),fatigue (68.9％),cough (48.9％),chest tightness (26.7％),chest pain (33.3％),syncope (8.9％),et al.The most common physical signs were splitting of the second sound in pulmonary valve area (93.3％),followed by tricuspid murmur (77.8％),cyanosis (53.3％),hepatomegaly (42.2％),hydropericardium (28.9％),and oedema (11.1％),et al.Twenty-seven cases did cardiac catheterization,compared with idiopathic PAH and secondary PAH,pulmonary artery systolic pressure,mean pulmonary artery pressure,pulmonary capillary wedge pressure,pulmonary arteriolar resistance index had significant difference(P ＜ 0.05).Thirty-one cases' condition improved after treatment,11 cases without any improvement and 3 cases died during follow-up visit.Conclusions PAH is a rare disease with no specific symptom and can be easily misdiagnosed in children.Ultrasonic cardiogram and cardiac catheterization are helpful in diagnosis.Actively looking for the cause can improve the prognosis.

OBJECTIVE To investigate the protective effect of total alkaloids of Rhizoma Corydalis (TARC) on experimental gastric mucosal lesions in rats. METHODS Gastric mucosal lesions were induced in rats by injecting acetic acid under gastric mucosal. From the 2nd day post the preparation of the rat model, cimetidine 400 mg · kg-1 or TARC 20, 40 and 80 mg · kg-1 was ig delivered for 15 d in different groups. Two days after the last delivery, gastric juice volume and total acidity were measured. Histopathology of stomach tissues was observed by HE staining. The area of gastric ulcer area was measured and the ulcer index and ulcer inhibitory rate were calculated. The expression of epidermal growth factor (EGF) and EGF receptor (EGFR) was detected by immunohistochemical staining. RESULTS Comparing with shame group, the eare of gastric ulcer and ulcer index were increased signifi?cantly in the model group(P<0.01), suggesting that the model rats were prepared properly. Compared with the model group, the ulcer area in rats of cimetidine and TARC 80 mg·kg-1 groups was decreased by 39.9%and 23.7%,respectively. The ulcer index was decreased by 52.3%and 30.5%,respectively. There was no significant difference between the cimetidine group and TARC 80 mg · kg-1 group, in the ulcer area or index. Compared with model group, EGF protein expression of cimetidine and TARC 40 and 80 mg · kg-1 groups was increased by 81.8%,24.2%and 57.6%,respectively while EGFR protein expression was increased by 45.9%,16.2%and 29.7%,respectively(P<0.05,P<0.01). Deciduous and necrotic gastric mucosal and a large amount of inflmmatory cells infiltration were observed in model group, and gastric mucosal lesions were improved in cimetidine and TARC 40 and 80 mg · kg-1 groups. CONCLUSION TARC has protective effect on gastric mucosal lesions in rats. The mechanism may be related to the increase of EGF and EGFR protein expression.
