Objective To evaluate the effect of resistance training on glucolipid metabolism in a population with pre-diabetic metabolism (PDM).Methods Sixty persons with PDM were randomly divided into a resistance training group,an aerobic training group and a control group,each of 20 members.The exercise intervention groups exercised 3 times a week for 12 weeks in accordance with the exercise prescription,while the control group was without any regular aerobic exercise or resistance training.Before and after the 3 months of exercise training,fasting blood glucose (FBG),2 hours postpradial blood glucose (PBG),HbAlc,and lipid profile were tested.Body mass index (BMI),waistline,and blood pressure were also measured.Results Before the intervention,there were no significant differences in any of the average values among the 3 groups.In the resistance group,the average FBS (5.52 ± 0.52 mmol/L),HbA1 c (5.92 ± 0.36％) and TG (1.65 ± 0.92 mmol/L) had all decreased significantly after the training.In the aerobic group the average waistline,dilated blood pressure,FBG and HbAlc had decreased significantly.In the control group the average 2hrs PBG and LDL-C had both increased significantly compared to 3 months earlier.Compared with the resistance group,the average 2hrs PBGs were significantly higher in both the aerobic and control groups after the training.Moreover,compared with the aerobic group,the value in the control group was also significantly higher.Conclusion Both resistance training and aerobic exercise can lower fasting blood glucose and HbA1 c in PDM patients without obvious effect on BMI or low density lipoprotein level.Compared with aerobic exercises,resistance training had significant advantages in decreasing 2-hour postprandial blood glucose.

Objective To explore the relationship between the genetic polymorphism and serum concentration of mannan binding lectin (MBL)and the clinical manifestation of the hand-foot-mouth disease (HFMD) children infection by human enterovirus 71 (HEV71).Methods One hundred and thirty-eight children diagnosed as HFMD infected by HEV71 (including 80 mild cases and 58 severe cases) and 40 healthy,symptom-free children were investigated.The concentrations of serum MBL were measured in 40 healthy controls,80 mild HFMD cases and 56 severe HFMD cases at both acute and convalescent phases by a sandwich enzyme immunoassay with a human MBL ELISA kit.And the genomic DNA of all cases were extracted from blood according to standard phenol-chloroform procedure.Six SNPs in the MBL gene(-550G/C,-221G/C and +4C/T of the promoter,CGT52TGT,GGC54GAC,and GGA57GAA of the exon 1) were analyzed by a sequencing-based typing method.Results The MBL serum level of the severe HFMD circulatory respiratory failure group in acute phase was significantly increased compared with severe HFMD encephalitis group,the mild cases and the control,but in the convalescence phase it significantly decreased compared with them.The frequencis of type B/B mutation (+230 of the exon 1),type P/P mutation (+4C/T of the promoter),and type H/H mutation (-550G/C of the promoter) were a significant difference among mild group,severe group and the control(P=0.006,0.043,0.028,respectively).The frequencies of LYPB/LYPB genotype and HYPA/HYPA genotype were a significant difference among mild group,severe groupand the control (P=0.028,0.014,respectively).Conclusion Low MBL protein level as a result genetic polymorphism seems to be correlative with clinical manifestation of HFMD disease.The MBL gene mutation and low MBI.protein level may be used as one of the evaluation method of HFMD severeity.

Objective To investigate the influence of perioperative administration of Ambroxol on pulmonary function, postoperative complications, postoperative hospital-stay and cost in elderly lung cancer patients after thoracic lobectomy surgery.Methods One hundred and forty consecutive elderly patients who underwent thoracic lobectomy surgery for lung cancer were randomly assigned into 2 groups: control group (n=70) and Ambroxol group (n=70).In control group, subjects were given the standardized treatment.In the Ambroxol group, patients were given the standardized treatment plus Ambroxol (90 mg/q, 8 h/d) from the day of operation to postoperative 5 days.The preoperative general information, intraoperative conditions, pulmonary function tests, arterial blood gases, incidence of perioperative morbidity, duration of ICU stay, length and costs of postoperative hospital-stay were collected and compared between the 2 groups.Results The 2 groups were well matched for demographics and operative variables.The forced expiratory volume in 1 second (FEV1),the forced vital capacity (FVC), peak expiratory flow rate (PEF) and arterial oxygen pressure were reduced in the 2 groups after operation as compared with before treatment, while the decreases of the above indexes were more significant in the control group than in the Ambroxol group (P＜0.05).Compared with the control group, the postoperative pulmonary complications declined, oxygenation index improved, the postoperative ICU occupancy rate and the length and costs of postoperative hospital-stay were decreased in the ambroxol group (all P＜ 0.05).Conclusions Perioperative administration of Ambroxol could reduce the incidence of pulmonary complications, improve the lung function, decrease the total hospitalization cost, shorten the length of hospital-stay, promote a rapid recovery after surgery, which is worthy of clinical application.
