Globally, individuals with chronic diseases now consume over 80% of all healthcare resources. Set against this depressing projection is decades of epidemiologic work demonstrating that 80%-90% of cardiovascular disease can be prevented via lifestyle and dietary interventions. How can we reconcile such contrasting views toward the future of cardiovascular health in human populations? Herein, we review available sources of evidence that can be used to answer these challenging questions of how and why. In particular, we submit that analytical framework incorporating the 6P (prediction, precision, personalization, prevention, population, and policy)-3G (good food, good environment, and good behavior)-4I (interpretation, integration, implementation, and innovation) will allow us to focus resource towards the development of multi-level approaches for the betterment of population

Histone deacetylase 1 ( sirtuin 1, SIRT1) is an important member of deacetylase family, and plays an important role in the process of malignant tumor and embryonic development. In this article it was found that overexpression of SIRT1 could accelerate the DNA synthesis in human pancreatic beta cell CRL-1837 and inhibit cell senescence. SIRT1 also could bind to p53 as detected by co-immunoprecipitation and could change the phosphorylation level of p53.

A HPLC-ELSD method was developed and validated for simultaneous determination of five Hetisane-type diterpenoid alkaloids in a Tibetan traditional herbal medicine, “Gebu Dilu” (Herba Delphinii), using a Kromasil C18 column (250 mm ? 4.6 mm, 5μm) with the mobile phase consisting of acetonitrile and 0.1% triethylamine in gradient (detected by evaporative light scattering detector). The linear ranges of five compounds were determined and method validation was evaluated completely. The established method is rapid and accurate with high repeatability, and can be applied for the quality control of Herba Delphinii.

OBJECTIVETo examine the effect of nickel-titanium rotary instruments in reducing post-operative pain.

METHODS95 molars with pulpal and/or periapical involvement were randomly assigned to two groups for root canal preparation. One group was treated with ProFile nickel-titanium rotary instruments; the other was treated by using stainless steel hand files-FlexoFile. The incidence and degree of post-operative pain after root canal preparation in the two groups were recorded.

RESULTSIn ProFile group, the incidence of post-operative pain was 27.7%, while 62.5% of the teeth developed post-operative pain after hand preparation. The difference between two groups was statistically significant (P < 0.01).

CONCLUSIONRoot canal preparation on molars with stainless steel hand files resulted in relatively high incidence of post-operative pain. Mechanical preparation using ProFile nickel-titanium instruments generated less post-operative pain and discomfort.

OBJECTIVE:To improve work efficiency and quality of pharmacy intravenous admixture services(PIVAS). METHODS:The information system of PIVAS in our hospital was optimized. The effects of the system were evaluated by comparing indexes 6 months before and after optimization. RESULTS:Compared with before optimization,the function of automatic repeated medical order checking was added to reduce the workload of manual prescription checking in respect of medical order checking;various batch generation rules were set up to reduce the number of adjusted batch by hand in respect of batch arrangement;label number and signature function were added to realize the information traceability function in respect of label printing and signature;rapid inquiry of transfusion state was realized by using two dimensional code scanning technology in respect of preparation scanning. When the daily workload increased and the staff did not increase,the number of daily manual checked medical orders were 956 before optimization and 257 after optimization;the time of daily labeling and dispensing were 180 min before optimization and 135 min after optimization;the number of monthly delivery error were 3.6 before optimization and 2.5 after optimization. CONCLUSIONS:Optimized function of information system can improve the work efficiency and work quality of PIVAS.

Objective To investigate the expressions of microRNAs (miRNA) and cytokines in the peripheral blood mononuclear cells (PBMCs) of patients with hepatitis B virus (HBV) infection and analyze their relationship with inflammation. Methods PBMCs were collected from acute hapatitis B (AHB) patients of 3 groups, including acute episode, virus clearance, recover period, and chronic hepatitis B (CHB) of mild, medium, severe type, and HBV-related liver cirrhosis. Each group included 20 patients, and 17 healthy donors were as control. Reverse transcription-polymerase chain reaction was used to measure miRNA146, miRNA155, miRNA181, interferon (IFN)-α, IFN-β,interferon induced gene 54 (ISG54) and interferon regulate factor 5 (IRF5). Comparisons among groups were done by one factor analysis of variance. Results The expression of miRNA155 was high in acute episode of AHB (2. 386± 1. 835), and higher than healthy control (1. 498± 1. 276) (F=1. 137,P-=0. 045), while reduced in acute episode, virus clearance (1. 633±2. 291), and recover period (0. 642±0. 836) (F=2. 122,P=0. 022). The expressions of IFN-α and IFN-β in AHB reduced in acute episode, virus clearance and recover period ( F = 1. 880, P = 0. 038 ; F= 1. 835, P = 0. 048).The expression of miRNA155 in AHB is closely correlated with IFN-α and IFN-β (r = 0. 483, P=0. 004; r= 0. 660, P= 0. 0002, respectively). In addition, in HBV infectious patients, the expression of miRNA155 was correlated with alanine transarninase (ALT), serum bilirubin (TBil) (r=0. 342,P=0. 006; r=0. 322, P= 0. 011, respectively), but not with HBV DNA load. Compared with healthy control (1. 307+ 0. 935), miRNA181 was higher in patients with HBV infection (F= 2. 072, P=0. 045) except AHB in recover period (1. 873±0. 998). There was no statistical difference in the miRNA146 expression between various groups. Conclusions The exprossion of miRNAs might be involved in the host anti-HBV immune response during HBV infection, and closely correlated with expression of IFN-related immune factors.

OBJECTIVETo investigate the changes in circulating plasmacytoid dendritic cells (pDCs) in patients with chronic hepatitis B (CHB) during the course of treatment with pegylated-interferon alfa-2s (peg-IFNa-2a) and to determine the correlations with therapeutic response.

METHODSForty-one patients with CHB who were receiving peg-IFNa-2a antiviral treatment for 48 weeks were enrolled in the study.Expression of the Toll-like receptor 9 (TLR9) on and frequency and functionality of the pDCs were analyzed at treatment weeks 0, 2, 12, 24, 36 and 48.

RESULTSAll patients exhibited an initially rapid decrease in the numbers of circulating pDCs and showed CpG-induced endogenous IFNa production within the first 2 weeks of treatment.Subsequently, all responders displayed a continuous increase in pDC numbers as well as functionality, both of which peaked around week 12 of treatment; in addition, these treatment responses were accompanied by significantly increased levels of type 1 T helper cytokines (P less than 0.05), which did not occur in the non-responders.

CONCLUSIONpDCs are involved in the initial therapeutic immune response stimulated by peg-IFNa-2a treatment.Recovery of blood pDC number and functionality may represent a predictor of favorable response to peg-IFNa-2a antiviral treatment in patients with CHB.

Sleep disorders commonly exist and are the earliest clinical symptoms in Alzheimer's disease (AD). At present, the molecular mechanism of AD caused by sleep disorders is not clear. Recent studies have found that sleep disorders can promote the accumulation of beta amyloid (Aβ) in the brain to form amyloid plaques with toxic effects. The increased Aβ inhibits the synaptic transmission pathway and induces abnormal phosphorylation of tau protein, which eventually leads to synaptic dysfunction. In addition, the inflammatory and stress response induced by Aβ are also associated with AD. Therefore, the improvement of sleep disorders may be a new pathway for the treatment of AD, in which light therapy is proved to be particularly effective. This article reviewes the latest progresses in the influences of sleep disorders in pathogenesis and treatment of AD in recent years.

Objective:To investigate the serotype features of group B Streptococcus (GBS) vaginal colonization in late pregnancies and their relationship with early-onset neonatal GBS disease (GBS-EOD). Methods:Thirty-two strains were isolated from neonates delivered by GBS-positive mothers and hospitalized for GBS-EOD in Xiamen Maternal and Child Care Hospital from June 2016 to June 2018. Another 266 strains were isolated from vaginal samples from randomly selected late pregnant women who received antenatal screening and delivered in the same hospital during the same period with an allocation ratio of 12∶1. A total of 298 strains from mothers and 32 strains from neonates were involved. Every isolate was serotyped with latex agglutination assay. GBS infection caused by eleven serotypes and the correlation between GBS serotypes in late pregnant women and neonatal GBS-EOD were analyzed. Qualitative variables were compared using Chi-square or Fisher's exact test. A correlation analysis was presented by the column contact number C. Multiple analysis of multiple sample rates was performed with Post hoc testing. Differences between groups were analyzed according to the adjusted standardized residual. Results:A total of nine serotypes were identified among the 298 strains isolated from the mothers. The most prevalent serotype wasⅢ [55.0% (164/298)], followed byⅠb [16.4% (49/298)], Ⅰa [11.1% (33/298)], Ⅴ [9.4% (28/298)], Ⅱ [5.0% (15/298)], non-typable [NT, 1.0% (3/298)], and Ⅵ, Ⅷ and Ⅸ [0.7% (2/298) in each]. Neither Ⅳ nor Ⅶ serotype was identified. The 32 strains isolated from neonates with GBS-EOD belonged to five serotypes, which were Ⅲ [18/32 (56.3%)], Ⅰa [8/32 (25.0%)], Ⅰb [3/32 (9.4%)], Ⅱ [2/32 (6.2%)] and Ⅴ [1/32 (3.1%)]. The positive rates of GBS Ⅲ serotype in neonates with pneumonia, sepsis, and meningitis were 6/13, 7/14, and 5/5. However, no statistically significant difference was observed in the distribution of the five serotypes in GBS-EOD neonates ( P=0.654). Thirty neonates (93.7%) were cured, while two (6.3%) died. There were statistically significant differences among neonatal GBS-EOD caused by vertical transmission with Ⅰa, Ⅰb, Ⅱ, Ⅲ and Ⅴ, Ⅵ, Ⅷ, Ⅸ and NT serotypes ( P=0.046, contingency coefficient: 0.183). Further analysis showed that the adjusted absolute value of the standardized residual of serotype Ⅰa was 2.7 (>2), and the difference was statistically significant. However, the adjusted absolute value of the standardized residual of serotype Ⅲ was only 0.1, which was not statistically significant. Conclusions:Serotype Ⅲ is the most prevalent GBS serotype in late pregnant women and GBS-EOD neonates, and also the predominant serotype in infants with early-onset meningitis. Serotype Ⅰa could be highly vertically transmitted, while the virulence of serotypes Ⅲ and Ⅰa strains of GBS are the strongest.

Objective To explore the effect of low-level laser therapy (LLLT)applied to the quadriceps muscle on the recovery of exhausting-cycling-exercise-induced fatigue.Methods According to a randomised,double-blind and crossover design,16 healthy male students were randomly assigned to an LLLT-1,LLLT-3,LLLT-5 and a placebo group,and received LLLT for 300 s at the dosage of 0.06 J· cm-2,0.18 J·cm-2,0.3 J·cm-2 and 0 to the bilateral rectus femoris after the exhausting-cycling-exercise-induced fatigue.The blood lactate(BL),heart rate(HR),rated perceived exertion(RPE)and visual analogue scale(VAS)were assessed before the exercise,immediately after exercise,10 and 20 min after exercise,as well as immediately after the first Wingate(WG)test,5 and 30 min after the WG test.Meanwhile,the second WG test was performed 40 min after the first WG test.Results The average HR value of LLLT-1 group was significantly lower than the placebo group at 10 min after exercise(P＜ 0.05)and immediately after the WG test(P＜0.01),while that of LLLT-3 and LLLT-5 groups was significantly lower than the placebo group immediately and 5 min after the WG test(P＜0.01).Compared to the placebo group,the average BL of LLLT-1,LLLT-3 and LLLT-5 groups was significantly lower 10 min after exercise(P＜0.05 for all)and that of LLLT-5 group was also significantly lower 30 min after the first WG test(P＜0.05).However,the average blood glucose of LLLT-5 group was significantly higher than the placebo group right after the first WG test(P＜0.05).Moreover,significant increase was observed in the mean(P=0.002)and peak power(P=0.006)at the second WG test and the mean(P=0.048) power at the first WG test of LLLT-3 group,compared to the placebo group.Conclusion LLLT applied to quadriceps muscles after exhausting exercise may enhance recovery,and LLLT at the dose of 0.18 J·cm-2 is of the best effect.
