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 compare the efficacy of internal fixation with non-operative treatment of traumatic flail chest combined with sternal fracture.Methods A retrospective review was made on 102 patients with traumatic flail chest combined with sternal fracture treated from January 2007 to January 2014.There were 71 patients in operation group and 31 patients in non-operation group.Operation group was allocated to pure titanium rib plating (Group Ⅰ,22 cases),porous titanium screw fixation (Group Ⅱ,20 cases),and nickel-titanium memory alloy sternal rib plating (Group Ⅲ,29 cases).Rib traction was performed in non-operation group.Clinical results and incidence of complications were compared between the two groups.Results At 24 and 72 hours,operation group was superior over non-operation group with regard to HR [(100.4 ± 9.5) times/min vs (105.2 ± 10.1) times/min,(92.1 ± 9.9) times/min vs (102.1 ± 9.2) times/min],MAP [(97.7 ± 14.5) mmHg vs (91.0 ± 13.3) mmHg,(112.5 ± 15.2) mmHg vs (93.1 ± 13.8)mmHg] and CVP [(7.8 ±3.7)cmH2O vs (9.4 ±3.8)cmH2O,(6.2 ±2.9)cmH2O vs (9.1 ±3.2) cmH2 O] (P ＜ 0.05).Duration in ICU [(5.1 ± 0.8) days vs (9.3 ± 1.1) days],ventilation time [(4.5 ±1.0)days vs (8.2 ± 1.4)days],hospitalization time [(14.6 ±3.5)days vs (23.3 ±4.4)days] and incidence of complications were significantly lower in operation group than in non-operation group (P ＜ 0.05).Two months after discharge,tidal volume (VT) [(0.52 ±0.04)L vs (0.40 ±0.03)L],inspiratory capacity (IC)[(1.99 ±0.45)L vs (1.22 ±±0.33)L],forced vital capacity (FVC) [(3.52 ±0.51)L vs (2.44 ±0.42)L],total lung capacity (TLC) [(5.41 ±0.82)L vs (3.72 ±0.56)L] and forced expiratory volume in one second (FEV1) [(2.80 ± 0.43) L vs (1.95 ± 0.50) L] showed significantly better results in operation group than in non-operation group (P ＜ 0.05).Operation time,intraoperative bleeding and daily drainage volume were (38.8 ±9.2)min,(43.5 ±7.6)ml and (10.9 ± 1.1)ml in Group Ⅱ versus (62.5 ± 10.1)min,(100.0 ± 10.5) ml and (26.8 ±3.1)ml in Group Ⅰ and (49.3 ±9.6)min,(61.4 ±8.3)min and (19.8 ±1.6)ml in Group Ⅲ (P ＜ 0.01).Conclusion For traumatic flail chest combined with sternal fracture,the internal fixation should be done as early as possible so as to reduce incidence of complications.Relatively,porous titanium screw fixation has better clinical outcome.

Objective To explore the therapy effect of candesartan plus CSDP on elderly hypertensive patients with renal dysfunction.Methods Eighty elderly patients with essential hypertension and renal dysfunction were selected as our subjects.All subjects were randomly divided into candesartan group and candesartan + CSDP group,every group for 40 subjects.Patients in candesartan group were treated with 4 mg candesartan once per day for 6 months.Patients in candesartan + CSDP group were given CSDP 10 capsules three times / day beside 4 mg candesartan,once per day for 6 months.The levels of Cr,BUN,Ccr changes were measured.Results Two therapy strategies can decrease blood pressure and the decrease rate of blood pressure in candesartan + CSDP group was higher than that of candesartan group.The level of Cr,BUN in patients with candesartan + CSDP group after treatment performing were (104.6 ± 6.5) μmol/L,(6.21 ± 4.80) mmol/L,lower than that in before treatment (196.8 ± 2.6) μ mol/L,(9.84 ± 3.20) mmol/L.And the Ccr increased from (58.1 ± 4.9)ml/min to (117.2 ± 6.4)ml/min.The differences were significant (t =2.213,2.302,2.136,P ＜ 0.05).However the differences between before and after treatment with only candesartan treat weren't significant (P ＜ 0.05).Conclusion Candesartan + CSDP might show a synergistic effect compared with candesartan in term of curing elderly hypertensive patients with renal dysfunction.

Objective To explore the behavioral patterns of middle school students and provide basis for unintentional injury prevention in these students.Methods 171 injury students and 171 normal students as controls were evaluated by Youth Self-Report(YSR),and mean scores were compared between the two groups by t Test.Logistic regressions were performed to analyze the relationship between injury students and behavioral problems.Results The rate was higher in injury group(15.79%) than in control group(8.19%).The score of injury group of boys was higher than thar of control group(t=2.942,P=0.004);the score of injury group of girls was higher than thar in control group(t=3.766,P=0.000).Multi-factor Logistic regression analysis showed that attention-deficit(OR=5.376),the problem of thinking(OR=3.672),social problems(OR=2.204) and friendly fellows' action was a risk factor.Conclusions There is a significant effect of the behavior of students and fellow students on the injury to students.

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 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.

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.
