Sarcopenia is common in chronic heart failure. The pathogenesis of chronic heart failure-related sarcopenia is complex and diverse. Resistance training, as the main intervention for chronic heart failure-related sarcopenia, is widely applicated as effective and safe therapy.

Objective To analyze the relationship between knowledge on cardiovascular disease prevention and ideal cardiovascular health behaviors and factors in community elderly. Methods From December, 2015 to May, 2016, totally 400 elderly in communities with-out overt cardiovascular disease were conveniently sampled. The level of knowledge on cardiovascular disease prevention was measured by self-designed cardiovascular disease prevention questionnaire. And each of the ideal cardiovascular health components was collected. Re-sults A total of 390 responses were valid. 13.85%community elderly were with high level of the knowledge. There were significant differ-ences in the distribution of cardiovascular health indexes among various leves of the knowledge groups (χ2>9.974, P<0.05), except choles-terol (P>0.05). The level of the knowledge was positively correlated with the scores of cardiovascular health behaviors and health factors (r>0.354, P<0.01). The cardiovascular health score, health behaviors score, health factors score and number of ideal cardiovascular health in-dexes were significantly different among various levels of the knowledge groups (F>8.961, P<0.001). Conclusion The level of knowledge on cardiovascular disease prevention was positively correlated with cardiovascular health behavior and health factors. The scores of cardio-vascular health score, health behaviors score and health factors increased with the improvement of knowledge on cardiovascular disease pre-vention.

OBJECTIVETo explore the effect of Panax notoginseng saponin (PNS) on the activity and content of beta-secretase in the brain of senescence accelerated mouse-prone 8 (SAMP8) mice with Alzheimer's disease.

METHODSTotally 32 SAMP8 mice were randomly divided into the normal control group, the high dose PNS group (200 mg/kg), the low dose group (100 mg/kg), and the huperzine A group (0.3 mg/kg), 8 in each group. Equal volume of double distilled water was given to those in the normal control group. All medication was given by gastrogavage, once daily for two successive months. The activity of BACE1 was assayed by direct immunofluorescent method (DIF). The content of BACE1 protein was detected by Western blot.

RESULTSThe relative fluorescence units (RFU/microg) was 2.008 +/- 0.031 in the high dose PNS group, 2.221 +/- 0.029 in the low dose PNS group, and 2.267 +/- 0.076 in the huperzine A group, all lower than that in the normal control group (2.403 +/- 0.058; all P < 0.01). The content of BACE1 protein was 0.900 +/- 0.028 in the high dose PNS group, 1.000 +/- 0.032 in the low dose PNS group, and 0.837 +/- 0.080 in the huperzine A group, all lower than that in the normal control group (2.210 +/- 0.074, all P < 0.01).

CONCLUSIONPNS higher than 100 mg/kg could decrease the activity of BACE1 and down-regulate the content of BACE1 protein in the brain of SAMP8 mice.

Objective To explore the efficacy, safety, and factors that might influence the efficacy of antiPD-1 antibody-based therapy in advanced hepatocellular carcinoma in the real world. Methods The clinical features, efficacy, and safety in patients with advanced hepatocellular carcinoma who received anti-PD-1 antibody-based therapy were retrospectively analyzed. The survival status was followed-up. Results The objective response and the disease control rate were 21.8% and 76.4%, respectively. The overall incidence of adverse events during treatment was 81.8%, of which the incidence of grade 3/4 adverse events was 14.5%. The incidence of immune-related adverse events was 58.2% and the incidence of grade 3/4 immune-related adverse events was 3.6%, and no treatment-related death was observed. The median PFS of the 55 patients was 5.0 (95%CI: 3.9-6.1) months, and the median OS was 11.4 (95%CI: 6.5-16.3) months. Univariate and multivariate analyses showed that liver function Child-Pugh scores and performance status ECOG score were the influencing factors of the objective response rate and survival. Conclusion In the real world anti-PD-1 antibody-based therapy is safe and effective in patients with advanced hepatocellular carcinoma, in which the performance status ECOG score and liver function Child-Pugh score before treatment are independent prognostic factors influencing survival.

The specimens of ductal carcinoma in situ (DCIS) with early invasion, and specimens collected by core needle biopsy (CNB) tend to contain limited amount of invasive component, so it is imperative to explore a new technique which can assess HER2 gene status accurately for the limited invasive cancer component in these specimens. Dual staining technique of combining immunohistochemistry (IHC) for myoepithelial cells and single or dual probe chromogenic in situ hybridization (CISH) for HER2 gene was performed on routinely processed paraffin sections from 20 cases diagnosed as having DCIS with invasive cancer. Among them, 10 had fluorescence in situ hybridization (FISH)-confirmed amplification of HER2 and 10 had FISH-confirmed non-amplification of HER2. We successfully detected HER2 genetic signals and myoepithelial IHC markers (SMM-HC or CK5/6) simultaneously on a single section in all 20 specimens. Myoepithelial markers and HER2 signals detected by dual staining assay were consistent with those by individual technique performed alone. HER2 gene amplification results determined by dual staining assay were 100% consistent with those of FISH. Dual staining technique which allows simultaneous detection of myoepithelial marker protein and cancerous HER2 gene is feasible, and it has potential to be used in clinical practice for effective determination of HER2 amplification in limited invasive component.

OBJECTIVETo observe the acupuncture therapy effect on the urinary retention after radical: hysterectomy. METHODS METHODS: Eighty cases of urinary retention after radical hysterectomy were randomly assigned to: the treatment group and control group according to the random number table method, 40 cases in each group. From the 15th day post operation, the patients in the two groups started to be treated and 7 days as a course with 5 days treatment and 2 days interval. The treatment group applied acupuncture with modalities of common needling on Zusanli (ST36) bilaterally, electroacupuncture on Sanyinjiao (SP6), Shuidao (ST28), and Scalp Reproduction Area bilaterally, moxibustion on Shenque (CV8). The control group applied acupoint injection with vitamin B B12 12, and Sanyinjiao and Zusanli were selected. Take turns on both sides. The courses for the recovery, of bladder function and residual urine volume for those who had voluntary micturition more than 200 mL after the first and second course of treatment were compared between the two groups.

RESULTSWithin 1 course and 2: courses of treatment, the patients with bladder function recovery in the treatment group were 21 (21/40) and 36 (36/40), and those in the control group were 12 (12/40) and 29 (29/40), both with a significant difference (P<0.05). After the first course and second course, residual urine volume for those who had voluntary micturition more than 200 mL in the treatment group was 91.7 ± 17.5 mL and 93.5 ± 15.5 mL, in the control group 102.4 ± 13.7 mL and 102.5 ± 15.7 mL, both with a significant difference (P<0.05).

CONCLUSIONSCombination of acupuncture: modalities was better than acupoint injection for the recovery of bladder function in urinary retention after radical hysterectomy. It would shorten the course of treatment and get a better recovery, decrease urinary retention cases of refractoriness, and extending the treatment could raise the healing rate of urinary retention.

Objective To determine the circular DNA level of patients with hand foot and mouth disease (HFMD) and evaluate its potential clinical value.Methods Venous blood in 30 healthy children and 78 patients with HFMD within 3 days of onset of illness and convalescent period was collected.The level of plasma circular DNA was detected by duplex real-time polymerase chain reaction assay.Blood sugar,high-sensitive CRP(hs-CRP) and leucocyte were also detected.Results The level of circular DNA in control group was ( 6.57 ± 4.67 ) ng/ml.The level of circular DNA in ordinary and severe HFMD patients was ( 11.51 ±7.75) ng/ml and (20.59 ± 10.67 ) ng/ml before treatment,respectively.The levels of circular DNA in ordinary and severe HFMD patients were significantly higher than that in control group(P =0.021 ;0.000) ; the level of circular DNA in severe HFMD patients was significantly higher than that in ordinary HFMD patients( P =0.011 ).The level of circular DNA in severe HFMD patients after treatment were significantly lower than that before treatment( P =0.033 ).The level of circular DNA before treatment and after treatment in ordinary HFMD patients had no significant difference.The levels of blood sugar and hs-CRP in severe HFMD patients were higher than those in ordinary before treatment (P =0.045; 0.011 ).The levels of blood sugar and hs-CRP before treatment and after treatment in ordinary HFMD patients had no significant change.There was significantly positive correlation between the level of circular DNA and that of hs-CRP in HFMD patient(P =0.021 ),but there was no correlation between the level of circular DNA and that of blood sugar and leucocyte.Conclusions The level of circular DNA not only become an early identification marker of severe H FM D patients,but also become monitoring marker of effect of treatment.

BACKGROUNDMicroRNAs (miRNAs) function as essential posttranscriptional modulators of gene expression, and are involved in a wide range of physiologic and pathologic states, including cancer. Numerous miRNAs are deregulated in hepatocellular carcinoma (HCC). This study aimed to investigate the role of miR-27a in the development of HCC.

METHODSThe expression of MiR-27a was measured by quantitative real-time polymerase chain reaction (qRT-PCR). 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide was used to examine changes in the viability of HepG2, Bel-7402, Bel-7404 hepatoma cell lines associated with up-regulation or down-regulation of miR-27a. A dual-luciferase activity assay was used to verify a target gene of miR-27a. Immunohistochemistry, qRT-PCR, Western blotting analysis, and cell cycle and apoptosis flow cytometric assays were used to elucidate the mechanism by which miR-27a modulates liver cancer cell proliferation.

RESULTSThe expression of miR-27a was significantly increased in HCC tissues and HepG2, Bel-7402, Bel-7404 hepatoma cell lines (P < 0.05). We also found that the down-regulation of miR-27a in HepG2 cells dramatically inhibited proliferation, blocked the G1 to S cell cycle transition and induced apoptosis (P < 0.05). In addition, miR-27a directly targeted the 3'- untranslated region of peroxisome proliferator-activated receptor γ (PPAR-γ), and ectopic miR-27a expression suppressed PPAR-γ expression on the mRNA and protein levels. The rosiglitazone-induced overexpression of PPAR-γ attenuated the effect of miR-27a in HCC cells.

CONCLUSIONSOur findings suggested that miRNA-27a promoted HCC cell proliferation by regulating PPAR-γ expression. MiR-27a may provide a potential therapeutic strategy for HCC treatment.

OBJECTIVE: To explore the genetic etiology of fetuses with congenital anomalies of the kidney and urinary tract (CAKUT) by whole exome sequencing (WES). METHODS: WES was performed on DNA extracted from cord blood samples of 26 fetuses with unexplained CAKUT with/without other structural anomalies. In the first 19 cases, sequencing was performed on fetal DNA only, and the turnaround time was 11-12 weeks. For the remaining 7 cases, the fetus and its parents were sequenced simultaneously, and the turnaround time was 8-9 weeks. RESULTS: Of the 26 cases, pathogenic variants were identified in 4 (15.4%) cases, which respectively involved UMOD, NEK8, HNF1B, and BBS2 genes, and likely pathogenic variants were identified in 2 (7.7%) cases, which respectively involved HSPD1 and GRIN2B genes. Two of the 4 cases had other anomalies in addition to CAKUT. Thus, the detection rate was only 2/19 (10.5%) for isolated CAKUT and 4/7 (57.1%) for CAKUT with additional anomalies. CONCLUSION The application of WES as a prenatal diagnostic approach for CAKUT fetuses with or without other anomalies allowed early and accurate diagnosis and improved their clinical management.
