strains that could produce raw starch-digesting glucoamylase were isolated from soil and mildewed rice.The highest raw starch-digesting glucoamylase activity strain named OR-1 was identified as Rhizopus.sp.The raw starch-digesting glucoamylase activity of the strain is 90U/mL.Through UV and NTG mutagenesis,the raw starch-digesting glucoamylase activity raised to 200U/mL and 325U/mL respectively.The RDA were 70% and 65% respectively.

Objective To investigate the roles of phosphatidylinositol 3-kinase/protein kinase B (PI3K/AKT) signaling pathway and its regulatory protein peroxisome proliferator-activated receptor γ (PPAR γ) and phosphatase and tension homologue deleted on chromosome 10 (PTEN) in regulating insulin sensitivity in rats with fetal growth restriction (FGR).Methods Sixteen pregnant rats were randomly divided into two groups including FGR and control groups on the 12th day of pregnancy (eight in each group).The FGR group was given low protein diet (8％ of casein) and restriction diet to establish the neonatal rat model of FGR.All maternal rats after delivery and newborn rats after weaning on 21 days after born were fed with normal diet.Each time blood samples were collected from eight newborn rats of each group to measure levels of fasting plasma glucose (FPG) and fasting insulin(FINS) at the time points of 21 days,two and four months after birth.Then insulin resistance index (IRI) and insulin sensitivity index (ISI) were calculated to evaluate insulin sensitivity.Expression of PI3K,AKT,PPAR γγ,PTEN and glucose transporters 4 (GLUT4) in skeletal muscle at mRNA and protein levels were measured at 21 days,two and four months after birth with real time fluorescence polymerase chain reaction and Western blot,respectively.Relationships between the expression of key molecules of PI3K/AKT signaling pathway and insulin sensitivity were analyzed.T-test,and Pearson's correlation analysis were used for statistical analysis.Results (1) The average birth weight of newborn rats in the FGR group was lower than that of the control group [(4.37± 0.69) vs (7.03±0.55) g,t=-20.75,P＜0.05].The incidence of FGR in the FGR group was 93.33％ (70/75).(2) Compared with normal offspring,those in the FGR group showed significantly increased FPG [two months after birth:(5.53± 0.58) vs (7.49 ± 0.38) mmol/L,t=8.08;four months afterbirth:(6.35±0.66) vs (8.94±0.90) mmol/L,t=6.58],FINS [two months afterbirth:(9.18±0.66) vs (14.67± 1.90) mU/L,t=7.71;four months after birth:(33.08±2.76) vs (56.33±2.81) mU/L,t=16.71] and IR1 (two months after birth:2.25±0.31 vs 4.90±0.81,t=8.63;four months after birth:9.30±0.90 vs 22.44±3.10,t=1 1.51),but decreased ISI (two months after birth:0.020 ± 0.002 vs 0.009± 0.001,t=-10.1 4;four months after birth:0.005±0.000 vs 0.002 ±0.000,t=-14.91) at two and four months after birth (all P＜0.05).(3) Compared with normal offspring,those in the FGR group showed decreased expression of PI3K (21 days after birth:0.082±0.028 vs 0.019±0.004,t=-6.29;two months after birth:0.020±0.003 vs 0.010±0.005,t=-4.78;four months after birth:0.014±0.004 vs 0.003±0.001,t=-7.87) and GLUT4 (21 days after birth:0.132±0.057 vs 0.041 ±0.019,t=-4.32;two months after birth:0.183±0.084 vs 0.069±0.017,t=-3.74;four months after birth:0.248±0.069 vs 0.113±0.040,t=-4.74) at mRNA level at 21 days,two and four months after birth (all P＜0.05).Compared with normal offspring,decreased expression of PPAR γ (two months after birth:0.028±0.002 vs 0.012±0.005,t=-3.70;four months after birth:0.030±0.008 vs 0.012±0.005,t=-3.80) and increased expression of PTEN (two months after birth:0.020±0.004 vs 0.045±0.014,t=5.09;four months after birth:0.023±0.007 vs 0.034±0.009,t=2.57) at mRNA level were observed in offspring of the FGR group at two and four months after birth (all P＜0.05).(4) Compared with normal offspring,expression of PI3K protein (21 days after birth:0.22±0.01 vs 0.17±0.02,t=-6.62;two months after birth:0.27±0.03 vs 0.16±0.02,t=-7.25;four months after birth:0.18±0.01 vs 0.09±0.02,t=-9.79) and GLUT4 protein (21 days after birth:0.21 ±0.01 vs 0.03±0.01,t=-27.29;two months after birth:0.10±0.01 vs 0.06t±0.01,t=-3.90;four months after birth:0.13 ±0.01 vs 0.08± 0.02,t=-8.10) decreased in offspring in the FGR group at 21 days,two and four months after birth (all P＜0.05).Compared with normal offspring,those in the FGR group showed decreased expression of PPAR γ protein (two months after birth:0.10 ± 0.01 vs 0.07± 0.01,t =-7.29;four months after birth:0.09±0.01 vs 0.08±0.01,t=-2.83),but increased expression of PTEN at protein level (two months after birth:0.10±0.01 vs 0.15±0.02,t=6.01;four months after birth:0.09±±0.01 vs 0.13±0.02,t=5.51) at two and four months after birth (all P＜0.05).(5) The IRI levels in offsprings in the FGR group were negatively correlated with the expression of PI3K,GLUT4 and PPAR γ at protein level (two months after birth:r=-0.90,-0.92 and-0.79;four months after birth:r=-0.92,-0.75 and-0.73,all P＜0.05),but positively correlated with the expression of PTEN at protein level (r=0.87 and 0.86,both P＜0.05) at two and four months after birth.Conclusions The abnormal expression of the key molecules of PI3K/AKT signaling pathway precedes the decrease of insulin sensitivity in newborn rats with FGR and the expression regulatory protein PPAR γ and PTEN are also changed,suggesting that these molecules may induce the impairment of insulin sensitivity in rats with FGR and be involved in the development of insulin resistance.

Objective To evaluate the effect of exercise on the relationship between body mass index (BMI) and health-related quality of life (HRQOL).Methods A total of 1 114 participants were recruited from the Physical Examination Center of two hospitals.SF-36 was used to measure HRQOL,and the classification of sports level was done according to the subjective evaluation of participants.Results The total score of HRQOL,physical component summary and mental component summary were 76.26± 16.10,75.97 ± 16.67 and 76.55± 18.33 respectively.The results of correlation analysis were as following:the positive correlation between BMI and general health (r=0.109),vitality (r=0.116),social functioning (r=0.092),role emotional (r=0.122),mental health (r =0.145) were significant (P＜ 0.01).The negative correlation between BMI and PF(r=-0.07,P=0.019)was significant.The mediation effects of exercise in was relationship between BMI and general health,vitality,mental health were significant,and the mediating effect were 5.84％,9.14％ and 6.58％.Conclusion This study demonstrates that mediation effects of the exercise are significant in some dimensions of HRQOL,but the direct influence of BMI on the HRQOL plays a leading role.And BMI is a protective factor under certain conditions.

AIM: The purpose of this study was to determine whether the signal transduction systems were activated at the molecular atrial tissue level in patients with atrial fibrillation (AF) and whether atrial expression of extracellular-signal regulated kinase (ERK) and protein phosphatases is altered. METHODS: Atrial tissue sample of 30 patients undergoing cardiac surgery were examined. 20 patients had AF, 10 patients had no history of AF. The mRNA expression of calcineurin B and MKP-1 were detected by semi-quantitative RT-PCR. ERK1 and phospho-ERK1 were analyzed at the protein level by Western blot. RESULTS: Western blot analysis showed that atrial fibrillation did not induce significant change in ERK1 expression level in the left atrium. In contrast , phospho-ERK1 content was increased in the patients with AF in comparison with those who had sinus rhythm (SR). The mRNA expression of calcineurin B and MKP-1 in the patients with AF were significantly higher than that in patients with SR. CONCLUSION: The activation of extracellular-signal regulated kinase and protein phosphatases may have correlation with the initiation or maintenance of atrial fibrillation.

Objective To explore the clinical effects of enema combined with massage therapy on jaundice in premature infants.Methods Seventy-five premature infants with jaundice were randomly divided into 3 groups,enema combined message therapy group(group A),abdominal massage therapy group(group B),and double-side phototherapy group(group C).All 3 groups were received the same formula fee-ding,intravenous nutrition and identical drug treatment.Group A was given enema with mixed kaiselu and normal saline together with 60 times clockwise abdominal massage once a day for 2 weeks.Group B only received abdominal massage twice per day for 2 weeks.Transcutaneous bilirubin(TB) indexes of all the premature infants in the 3 groups were detected and transformed into total TB concentrations every morning,through version of MINOLTA JM-102 transcutaneous bilirubin radiometer made in Japan.When TB index counted more than 196.58 ?mol/L,group A and B were given single-side phototherapy for 24 hours.Neither enema nor abdominal massage was given to group C,and double-side phototherapy was applied when TB indexes were above 196.58 ?mol/L.Daily TB indexes,duration of jaundice and phototherapy,time of meconium exhaustion,defecation times in each day,incidence of constipation and feeding intolerance were recorded.Results Duration of jaunhospitalized and phototherapy were significantly shortened in group A compared with those of the other groups.In 34 premature infants who were hospital for at least 2 weeks,TB indexes in group C were lower than those in group B on the 9th day.On the 12th day and the 14th day,TB indexes in group A and C were lower than those in group B(Pa

Background The pathogenesis of pterygium has been in the study.Relative molecular biology study showed that pterygium is a tumor-like lesion,and based on overseas literatures,human papillomavirus (HPV) is positively expressed in 100％ patients with pterygium in some region.However,if this result is suitable for Chinese patients is unclear.Objective This study was to identify the role of human HPV in the pathogenesis of pterygia in Wuxi area.Methods Forty-eight pterygium specimens including 7 recurrent pterygia and 41 primary pterygia were collected during the operation,and these patients were from Wuxi area.Two cervical carcinoma specimens and 2 conjunctiva specimens from normal donors were obtained as positive control and negative control respectively.The fluorescent quantitative polymerase chain reaction (FQ-PCR) was used to detect HPV DNA of specimens.Results The amplified curves of HPV 6,11 of pterygium specimens,cervical carcinoma specimens and normal specimens were all below the positive quality control curve,but the amplified curves of HPV16,18 were above the quality control curve in cervical carcinoma specimens; while those of pterygium specimens and normal conjunctival specimens were all below the quality control curve.HPV16/18 was identified in 2 cervical carcinoma specimens,but no HPV6/11 was detected in 2 cervical carcinoma specimens.However,HPV DNA expression in primary and recurrent pterygias were absent.Conclusions According to these results,HPV is not the primary cause for the pathogenesis of pterygium in Wuxi region.
