Chinese Journal of Primary Medicine and Pharmacy 2015;(21):3251-3255
Objective To investigate and analyze the relative factors in elderly men with type 2 diabetes mellitus(T2DM)complicated with osteoporosis(OP),thus to provide guidance for prevention of OP complicated with T2DM in elderly men.Methods Dual X -ray absorptiometry determination of bone mineral density (BMD)of 67 cases of elderly men with diabetes,men were divided into OP group (n =32),NOP group (n =35).Then,we compared differences in body mass index(BMI),diabetes duration,fasting plasma glucose (FPG),glycosylated hemo-globin(HbA1c),patients'age,fasting insulin(FINS),insulin sensitivity index(ISI),quantitative of urinary albumin (ALb),quantitative of urinary protein in 24 hours and alkaliphosphatase level(ALP),low density lipoprotein choles-terin(LDL -C),triglyceride(TG),and made correlation analysis.Results Compared with those in NOP group,pa-tients in OP group had older age,longer disease course,smaller baric index,lower BMD,higher ALP,lower FINS,low-er ISI,higher HbA1c,higher quantitative of urinary protein in 24 hours and urinary albumin,higher LDL -C,which were significantly different (P <0.05);BMD of elderly men with T2DM was negatively correlated to patients'age, disease course,HbA1c,quantitative of urinary protein in 24 hours,ALb,ALP and LDL -C,but positively correlated to BMI,FINS and ISI.Conclusion Many factors,such as elderly,low body weight,long duration of the disease,high level of blood sugar,insulin dysfunction,low insulin sensitivity,high level of blood suger,insulin dysfunction,low insulin sensitivity,high serum alkalinephosphatase,high LDL -C and diabetic nephropathy,contribute to osteoporosis in elderly men with T2DM.

Objective To evaluate the accuracy of bispectral index (BIS) in predicting outcomes in patients with cerebral hemorrhage.Methods A total of 103 patients of either sex with acute cerebral hemorrhage,aged 18-77 yr,with body mass index of 17-29 kg/m2,of American Society of Anesthesiologists physical status Ⅱ-Ⅳ,undergoing craniotomy for evacuation of hematoma,were enrolled in this prospective study.BIS electrodes were adhered to the forehead of patients,and the BIS value was continuously recorded for 20 min.The maximum BIS value (BISmax) and minimum BIS value (BISmin) were recorded,and the mean BIS value (BISmean) was calculated.The patients were divided into 2 groups according to Glasgow Outcome Scale (GOS) scores assessed at 6 months after surgery:good outcome group (GOS score≥ 3) and poor outcome group (GOS score 1 or 2).The receiver operating characteristic curve of BIS in predicting outcomes was plotted,and the area under the curve (AUC) and 95% confidential interval (CI) were calculated.The best cut point and sensitivity and specificity were calculated according to the BIS value when Youden index reached the maximal value.Results The AUC (95% CI) for BISmax in predicting outcomes was 0.903 (0.830-0.976),the best cut point 79,the sensitivity 84%,the specificity 86%,and Youden index 0.695.The AUC (95% CI) tor BISmin in predicting outcomes was 0.841 (0.760-0.921),the best cut point 43,the sensitivity 86%,the specificity 71%,and Youden index 0.577.The AUC (95% CI) for BISmean in predicting outcomes w() 0.883 (0.800-0.958),the best cut point 60,the sensitivity 90%,the specificity 76%,and Youden index 0 562.Conclusion BIS can accurately predict outcomes in patients with acute cerebral hemoorrhage,and BISmax provides the highest accuracy.

Objective To understand the current status of health knowledge demands and its associated factors in general population. Methods A questionnaire-based survey by convenience sampling method was carried out in 700 subjects aged over 15 years old in October 2014. Information of demographics and health knowledge demands were collected. Data was analyzed using SPSS 17.0. Results A total of 653 subjects were responded, with a response rate of 93.3%. Respondents in male and female were 339 (51.9%) and 314 (48.1%) respectively. There were no differences among age , educational levels and self-reported health status between the two genders 86.6% of the participants showed that they had interests in health knowledge. Educational level and age were the factors associated with the interests. 65.8% and 72.3% of people want to get practical health knowledge of western and traditional Chinese medicine respectively. The top concern of health issues were cardiovascular and cerebrovascular diseases. For preferred ways of learning health knowledge , television is the favorite one (44%), especially in elderly (over 63.8%). A relative high option rate was newspaper and magazine in all age groups. However, young people showed that they preferred the ways of the internet and Wechat (about 50%). For health disseminators, the participants in all age had greatest trust in experts in large hospitals (over 60%). The second option was retired old experts. The experienced patients were convinced in some degree and increased with age. Conclusions In future, health education in general population should considered the characteristics of the population and the applicability of knowledge. Besides , it is necessary to integrate traditional Chinese medicine with Western medicine, traditional media with new media, also authoritative experts and living example.

Objective To study the influence of carboxymethyl-chitosan(CM-chitosan)on chondro- cyte apoptosis induced by recombinant human interleukin-1?(rhIL-1?)and explore its mechanism.Methods Rabbit chondrocytes were isolated and cultured.Chondrocytes were pretreated with different concentrations of CM-chitosan for 1 h,then 10 ng/ml IL-1?were added into the culture medium.After 24 h,the apoptotic rates of chondrocytes were measured by flow cytometry with AnnexinⅤ-FITC and PI staining.The morphology of nuclei was observed by fluorescent microscopy with Hoechst 33342 staining.The mitochondrial membrane po- tentials were tested by confocal laser scanning microsocopy with Rhodamine-123 and ATP contents were mea- sured by luciferase reaction.Results CM-chitosan could inhibit chondrocyte apoptosis and restore the func- tion of mitochondria induced by IL-113 in a dose-dependent manner.Conclusion CM-ehitosan can inhibit chondrocyte apoptosis by protecting mitochondrial function.

Rotavirus capsid protein Vp4 plays an important role in the virus adhering and entering the cells. In this study, a Vp4 gene cloned from a rotavirus strain TB-Chen was highly expressed in E.coli BL21 (DE3). The results of the Western blot showed that the protein possesses specific immuno-reactivities and can be specifically recognized by guinea pig antibodies against rotavirus strain SA11 or Wa. Some Vp4 dimers were formed during renaturation. These data obtained from this study provide a strong basis for further study on the structure and function of the Vp4.

Objective To investigate the effects of Kinesio taping on function of knees in girls. Methods 20 female students were tested the peak torque of centripedal and eccentric contraction of knee flexion and extension with Biodex isokinetic testing at 60°/s angular velocity, with Kinesio taping, placebo taping and without taping. Their amplitude root of mean square (RMS) of surface electromyography of vastus medialis (VM), rectus femoris (RM) and vastus lateralis (VL) were also recorded. Results For centripedal isokinetic contraction, the relative extensors peak torque was the most as Kinesio taping (P<0.01). There was no significant difference in relative flexor peak torque (P> 0.05). Standardized RMS of VM and VL were the least as Kinesio taping (P<0.01), but not significantly different of RF among all the conditions (P>0.05). For eccentric isokinetic contraction, the relative extensor peak torque of both extensors and flexors were the most as Kinesio taping (P<0.01), while the Standardized RMS of VM and VL were the least (P<0.01), but no significant difference was observed in RF (P> 0.05). Conclusion Kinesio taping may enhance the strength of centripedal, eccentric contractions of quadriceps and eccentric contractions of hamstring, and increase the muscle fibers recruitment of VM and VL.
