RESUMEN
OBJECTIVE@#To compare the effect of acupuncture at Huiyin (CV 1) and oral administration of western medication in treatment of chronic severe functional constipation (CSFC).@*METHODS@#A total of 64 patients with CSFC were randomly divided into an acupuncture group (32 cases, 5 cases dropped off) and a western medication group (32 cases, 4 cases dropped off). Both groups were given routine basic treatment. The acupuncture group was treated by directly puncture of 20-30 mm at Huiyin (CV 1), once a day for the first 4 weeks, 5 times a week, once every other day for the next 4 weeks, 3 times a week, totally for 8 weeks. The western medication group was treated with 2 mg prucalopride succinate tablets orally before breakfast every day for 8 weeks. The average number of weekly spontaneous bowel movement (SBM) of the two groups were observed before treatment and 1-8 weeks into treatment. The constipation symptom score before and after treatment, and in follow-up of 1 month after treatment, as well as quality of life [patient assessment of constipation quality of life questionnaire (PAC-QOL) score and the proportion of patients of PAC-QOL score difference before and after treatment≥1] before and after treatment were compared in the two groups. The clinical effects of the two groups were evaluated after treatment and in follow-up.@*RESULTS@#Compared before treatment, the average number of weekly SBM in the two groups was increased 1-8 weeks into treatment (P<0.05). The average number of weekly SBM in the acupuncture group was less than that in the western medication group 1 week into treatment (P<0.05), and the average number of weekly SBM in the observation group was more than that in the western medication group 4-8 weeks into treatment (P<0.05). The scores of constipation symptom after treatment and in follow-up and scores of PAC-QOL after-treatment in the two groups were lower than those before treatment (P<0.05), and those in the acupuncture group were lower than the western medication group (P<0.05). The proportion of patients of PAC-QOL score difference before and after treatment≥1 in the acupuncture group was higher than that in the west medication group (P<0.05). The total effective rates after treatment and in follow-up in the acupuncture group were 81.5% (22/27) and 78.3% (18/23), respectively, which were better than 42.9% (12/28) and 43.5% (10/23) in the western medication group (P<0.05).@*CONCLUSION@#Acupuncture at Huiyin (CV 1) can effectively increase the number of spontaneous defecation in patients with CSFC, reduce constipation symptoms, improve the quality of life, and the effect after treatment and in follow-up is better than oral western medication.

Aim To investigate the sites and mechanisms of action of Ginseng-Rhodiola rosea in the treat ment of myocardial ischemia-reperfusion injury ( MI-RI) via using network pharmacology approach, molecu¬lar docking techniques and experimental studies. Methods The active ingredients and targets of Gin¬seng-Rhodiola rosea were screened through the TCMSP database and literature supplementation, and the GEN-EC ARDS ,DISGENET and DRUGBANK databases were searched to obtain the targets of MIRI. Functional pro¬tein interaction networks (PPIs) and the STRING database were used to screen out core targets. The DAVID database was also selected for gene ontology functional analysis ( GO) and KEGG signaling pathway enrich¬ment analysis. Lastly, the preliminary validation was performed with the help of molecular docking techniques and experimental studies. Results Forty-three active ingredients and 348 potential targets of Ginseng-Rhodiola were obtained, and targets such as IL-6 , TNF-α and VEGFA were found to be closely related to MIRI, mainly involving TNF, PDK-Akt, HIF-1 and other signaling pathways.The molecular docking results showed that soysterol, ginsenoside rh2 and rhodioloside had good binding effects and high matching with IL-6, TNF-α,Caspase-3,VEGFA,MAPK1 and other targets, among which the best binding was between Caspase-3 and ginsenoside rh2. The results of the experimental study further showed that Ginseng-Rhodiola rosea could improve myocardial tissue necrosis after myocardial ischemia-reperfusion , reduce myocardial cell edema and vascular congestion, and decrease the expression levels of TNF-α and IL-6 in MIRI rats. Conclusions Ginseng-Rhodiola may modulate multiple targets such as IL-6,TNF-α, Caspase-3, VEGFA and MAPK1 through dousterol, ginsenoside rh2 and rhodiol glycosides to inhibit inflammatory response and oxidative stress, reduce cardiomyocyte damage and exert therapeutic effects on MIRI.
RESUMEN
OBJECTIVE@#To study two novel CD36 gene mutations at the CD36 splicing sites found in Guangxi population, as well as the molecular basis and population incidence of them.@*METHODS@#DNA sequencing and cDNA clonal sequencing were used to detect CD36 exon sequence and the protein coding region sequence of CD36 mRNA for 2 CD36 deficient individuals (HHC and WGM) found in Guangxi population. Eukaryotic expression cell lines were established for the discovery of CD36 mRNA abnormal transcripts and Western blot assay was used to verify the effect of abnormal CD36 mRNA transcripts on CD36 expression. A DNA PCR-SSP genotyping method was established for the two CD36 novel mutations, and the population distribution was investigated among 110 CD36 deficient individuals in Guangxi region and 296 random individuals in Guangxi population.@*RESULTS@#Novel mutation of c.430 -1G>C was found at the CD36 splicing site in HHC and WGM individuals, and novel mutation of c.1006 +2T>G at the CD36 splicing site was also found in the WGM individual. CD36 cDNA clonal sequencing showed that CD36 c.430 -1G>C could lead to the production of the two CD36 mRNA transcript variants: c.429_430ins[430-17_430-2;C](p.Ala144fsTer1) and c.430_609del(p.Ala144_Pro203del)(GenBank:HM 217023.1); and CD36 c.1006 +2T>G could lead to the production of CD36 mRNA transcript variant of c.819_1006 del (p.Ser274GlufsTer16) (GenBank: HM217025.1). It was verified that all the three transcript variants could lead to CD36 deficiency by establishment of eukaryotic expression cell lines and Western blot assay. A study of the population incidence of two novel CD36 splicing site mutations found showed that in 110 CD36 deficient individuals and in 296 random individuals in Guangxi region, the mutation rate of CD36 c.430 -1G>C was 10.91% (12/110) and 1.35% (4/296), respectively, while CD36 c.1006 +2T>G was 2.73% (3/110) and 0 (0/296), respectively.@*CONCLUSION@#This study identifies two novel CD36 mutations at CD36 splicing site, and preliminary clarified their molecular basis for the CD36 deficiency and the distribution characteristics in Guangxi population as well. It provides an experimental and theoretical basis for studying the molecular mechanism and characteristics of CD36 deficiency in Chinese population.

BACKGROUND: Human umbilical cord-derived mesenchymal stem cells, because of convenient acquisition, will not bring pain and adverse effects to the fetus and their parturient. The success rate of culture is high. It has good application prospects in the treatment of myocardial infarction. OBJECTIVE: To review the new progress of human umbilical cord-derived mesenchymal stem cells transplantation in the treatment of myocardial infarction. METHODS: A computer-based online search of PubMed and Wanfang databases was performed to retrieve the related articles published from 1991 to 2017. We reviewed the initial data and the quotations from each document. Finally, we included randomized controlled animal experiments or clinical studies concerning human umbilical cord-derived mesenchymal stem cells for treatment of myocardial infarction. RESULTS AND CONCLUSION: Human umbilical cord-derived mesenchymal stem cells will become a new alternative source of cells in the treatment of myocardial infarction, with extremely broad prospects. However, there is no mature conclusion about the convenient route, optimal number of transplanted cells, optimal timing, differentiation, homing and evaluation after transplantation, which limits the clinical application of these cells.
RESUMEN
To investigate the association between fasting plasma glucose [FPG], 2-hour post challenge plasma glucose [2hPG], fasting plasma insulin [FINS], 2-hour post challenge plasma insulin [2hINS], and cardiovascular risk factors in obese and overweight children. This is a cross-sectional study of 452 obese and overweight children [male: 312, female: 140, aged 6-16 years]. This study was conducted in the Department of Pediatrics, General Hospital of Tianjin Medical University, Tianjin, China between June 2008 and November 2012. Anthropometries and blood analysis were carried out. Pearson correlation analysis and multiple stepwise linear regression analysis were used to investigate the association among FPG, 2hPG, FINS, 2hINS and cardiovascular risk factors. Body mass index, waist circumference, waist to hip ratio, systolic blood pressure, diastolic blood pressure, and triglyceride were highly correlated with FINS. Fasting plasma insulin influenced greater variance in most cardiovascular risk factors than 2hPG and 2hINS. Fasting plasma insulin was closely associated with most cardiovascular risk factors compared with FPG, 2hPG and 2hINS
RESUMEN
<p><b>BACKGROUND</b>Graves' ophthalmopathy/orbitopathy (GO) patients often suffer ocular surface damages and tear fluid proteins play a significant role in maintaining healthy ocular surfaces, while changes in tear protein components reflect the changes ocular surface abnormalities. In this study proteomics techniques were used to investigate tear protein compositions in GO patients.</p><p><b>METHODS</b>We carried out a case-control study by comparing tear fluid contents of GO patients with that of healthy subjects. In the first step the tears were subjected to SDS-PAGE electrophoresis and then single protein bands were analyzed by to in-gel trypsin digestion and nano-flow liquid mass spectrometry (LC-MS/MS) using a MS software.</p><p><b>RESULTS</b>In tear samples of GO subjects, the protein fractions of inflammation-related protein immunoglobulin kappa chain C region (IgKC) and serum albumin were essentially reduced, whereas a novel isoform of complement component 3 (C3), which we detected in control subjects, was completely absent in the GO patients' tears.</p><p><b>CONCLUSIONS</b>Reduced protein concentrations of particularly IgKC and complement C3 as well as albumin in the tears of GO patients may contribute to changes in their ocular surfaces via diminished reactive oxygen species (ROS) depletion and adaptive immune responses. The completely absent of C3 in the GO patients' tears, may imply that an important inflammatory signaling pathway is affected, which needs further investigation.</p>

<p><b>OBJECTIVE</b>To investigate the correlation between visceral adipose tissue-derived serine protease inhibitor (vaspin) concentration and insulin sensitivity in the visceral adipose tissue of young obese Sprague-Dawley (SD) rats.</p><p><b>METHODS</b>Twenty-four SD rats which had been weaned 3 weeks before were randomly divided into two groups (n=12 each) to receive a high-fat and normal diet. The weight and abdominal circumference (AC) of each rat were measured, the fasting plasma glucose (FPG) and fasting insulin (FINS) in blood from the angular vein were measured after 12 hours of fasting and blood glucose (BG) and insulin (INS) levels in blood from the angular vein were measured at 60 and 120 minutes after intraperitoneal injection of 50% glucose (2 g/kg). The rats were sacrificed, and their liver and visceral adipose tissue were weighed. The vaspin concentration of the visceral adipose tissue in each rat was measured using ELISA. Correlation analysis was performed on the vaspin concentration and other indices.</p><p><b>RESULTS</b>Compared with the normal diet group, the high-fat diet group showed significantly higher weight, AC, weight of visceral adipose tissue, FPG, FINS, 120 minute INS level, vaspin concentration, homeostasis model assessment for insulin resistance (HOMA-IR) and homeostasis model assessment of β cell function (HOMA-β) (P<0.05) Insulin sensitivity index (ISI) was significantly lower (P<0.01). Vaspin concentration was positively correlated with visceral adipose tissue and liver weight, AC, 120 minute INS level, FPG, FINS, HOMA-IR and HOMA-β (P<0.05), and negatively correlated with ISI (P<0.05).</p><p><b>CONCLUSIONS</b>High expression of vaspin is associated with insulin resistance in young obese SD rats. Vaspin is presumably an adipocytokine that can increase insulin sensitivity, promote insulin secretion by islet β-cells and improve glucose tolerance, and it may be involved in insulin resistance and the disturbance of carbohydrate metabolism.</p>

<p><b>OBJECTIVE</b>To examine UVB-induced responses in normal human keratinocytes (HaCaT) and epidermoid carcinoma cells (A431) at the cellular and molecular level, and investigated the protective effect of salidroside.</p><p><b>METHODS</b>Cells irradiated by UVB at various dosage and their viability was assessed by MTT assays, cell cycle was analysed by flow cytometry. The expression of NF-κB, BCL-2, and CDK6 after 50 J/m(2) UVB irradiation were detected by RT-PCR and western blotting.</p><p><b>RESULTS</b>Our results confirmed greater tolerance of A341 cells to UVB-induced damage such as cell viability and cell cycle arrest, which was accompanied by differential expression changes in NF-κB, BCL-2, and CDK6. UVB exposure resulted in HaCaT cells undergoing G(1)-S phase arrest. When treated with salidroside, HaCaT survival was significantly enhanced following exposure to UVB, suggesting great therapeutic potential for this compound.</p><p><b>CONCLUSION</b>Taken together, our study suggests that A431 respond differently to UVB than normal HaCaT cells, and supports a role for NF-κB, CDK6, and BCL-2 in UVB-induced cell G(1)-S phase arrest. Furthermore, salidroside can effectively protect HaCaT from UVB irradiation.</p>

<p><b>BACKGROUND</b>A model of simulated Alzheimer's disease (AD) induced by aggregated amyloid protein (Abeta(1-40)) was built in Wistar rats to observe the behavioral and pathological changes of Abeta(1-40) and the effect of hypodermic insulin injected on the function of study and memory and the expression of Abeta(1-40) from the CA1 area of the hippocampus.</p><p><b>METHODS</b>Experimental groups were as follows: contrast, simulated AD model, contrast of Nacl, and insulin treated. The simulated AD model was built by microinjection of aggregated Abeta(1-40) at the CA1 area of the hippocampus, and was hypodermically injected with 0.9% NaCl (1 ml/kg) and insulin (0.1 U/kg) separately the next day. Two weeks after the modeling, the four groups were tested with water maze about the study and memory function of rats. Three weeks after the injection, the expression of Abeta(1-40) at the CA1 area of the hippocampus was examined by pathological tests (HE, Congo red) and immunohistochemical methods.</p><p><b>RESULTS</b>The study and memory abilities of rats were ameliorated significantly by the place navigation test and the spatial probe test after the application of insulin. Insulin could decrease the expression of Abeta(1-40) at the CA1 area of the hippocampus to reduce the pathological damage of Abeta(1-40) to the hippocampal area of rats.</p><p><b>CONCLUSIONS</b>The injection of aggregated Abeta(1-40) to the hippocampal area could simulate the behavioral and pathological features of AD such as the difficulty of study and memory and the damage to neurons. Insulin is effective to improve the function of study and memory and amend the pathological damage of simulated AD model rats. The results give a experimental proof of insulin in the clinical treatment of AD.</p>

<p><b>BACKGROUND</b>Thioredoxin is one of the most important redox regulating proteins. Although thioredoxin has been shown to protect cells against different kinds of oxidative stress, the role of thioredoxin in myocardial ischemia and reperfusion injury has not been fully understood. This study was conducted to explore the protective role of human thioredoxin on myocardial ischemia and reperfusion injury and its potential mechanisms.</p><p><b>METHODS</b>Purified human thioredoxin was injected into adult Wistar rats, which were subjected to 30 minutes of myocardial ischemia followed by 2 or 24 hours of reperfusion. We detected 1) the infarct size; 2) the level of malondisldehyde (MDA) in serum; 3) the expression of caspase-9, and cytochrome c in/out of mitochondria by Western blotting; 4) apoptosis by terminal-deoxynucleotidyl transferase mediated nick end labeling (TUNEL) assay and caspase-3 and its protein by reverse transcriptase polymerase chain reaction (RT-PCR) and Western blotting; 5) the expression of bcl-2 and bax in cardium by immunohistochemical (IHC) assay.</p><p><b>RESULTS</b>Human thioredoxin reduced myocardial ischemia/reperfusion injury as evidenced by significant decrease of myocardial infarct size (P < 0.01), notable reduction of myocyte apoptosis (P < 0.01), lower systemic oxidative stress level (P < 0.01) after reperfusion for 2 hours, and few inflammatory cell infiltration after reperfusion for 24 hours in rats. Furthermore, treatment with human thioredoxin significantly reduced the release of mitochondrial cytochrome C (P < 0.05), and inhibited the activity of caspase-9 (P < 0.05) and caspase-3 (P < 0.01 in mRNA and P < 0.05 at protein level). Meanwhile, human thioredoxin markedly increased bcl-2 expression (P < 0.05).</p><p><b>CONCLUSIONS</b>These results strongly suggest that human thioredoxin has cardioprotective effects on myocardial ischemia/reperfusion and its anti-apoptotic role may be mediated by modulating bcl-2 and the mitochondria-dependent apoptotic signaling pathway.</p>

<p><b>OBJECTIVE</b>Obesity is an important risk factor of insulin resistance and type 2 diabetes. Adipocyte is a cell that can actively secrete a series of factors to regulate the pathway responsible for energy balance. Resistin is one of these factors. The purpose of this study was to investigate possible correlation between resistin and certain parameters, including body parameters and other parameters of glucose metabolism and roles of resistin in hyperinsulinemia or insulin resistance in obese children.</p><p><b>METHODS</b>The serum resistin concentration was measured in 34 obese children (18 boys, 16 girls; age 8.9-15.9 years) and 31 normal subjects (16 boys, 15 girls; age 7.8-14.5 years) by using ELISA. Anthropometric parameters, fasting glucose and insulin were measured in all subjects. Insulin resistance was assayed by homeostasis model assessment ratio (HOMA-R). Beta cell function was determined by using homeostasis model assessment beta cell (HOMA-beta). Correlation analysis was performed between resistin and other parameters.</p><p><b>RESULTS</b>(1) The serum resistin concentration (common logarithmic transformation) was 3.1 +/- 0.5 in obese subjects and 2.7 +/- 0.8 in normal subjects. (P < 0.05). (2) The serum resistin concentration was not significantly correlated with sex, age, systolic and diastolic blood pressures, but was positively correlated with BMI, percent body fat (BF%), waist-hip ratio (WHR) (r = 0.299, r = 0.304, r = 0.322, P < 0.01); and positively correlated with fasting glucose, insulin, HOMA-R (r = 0.299, r = 0.303, r = 0.324, P < 0.05), but not significantly correlated with HOMA-beta. (3) Multiple linear regression analysis showed that only HOMA-R was the factor that significantly influenced resistin, R(2) = 0.105, the standard partial coefficient was 0.279 (P < 0.01).</p><p><b>CONCLUSIONS</b>The serum resistin concentration in obese children were higher than that in normal children. The serum resistin concentration significantly correlated with the degree of obesity and the distribution of fat. Resistin is probably related to occurrence of hyperinsulinemia and/or insulin resistance in obese children.</p>

<p><b>OBJECTIVE</b>To investigate the prevalence of domestic violence (DV) in Hunan.</p><p><b>METHODS</b>Using a multi-stage sampling strategy, 9451 households involving 32 720 persons in urban, rural and industrial areas in Hunan, China were studied. Multiform clue investigation and face-to-face interviews were combined to investigate the prevalence of DV.</p><p><b>RESULTS</b>A lifetime prevalence of DV was reported by 1533 households (16.2%). A total of 1098 households (11.6%) reported at least one incident of DV in the previous year. Both lifetime and 12-month prevalence of DV varied significantly by geographic setting (P < 0.01). The lifetime prevalence abuse rates were: spousal 10.2%, child abuse 7.8%, and elder 1.5%. With regard to household structure, the lifetime prevalence of DV was highest among those remarried families (21.0%), followed by married couples with one child and extended families with several generations living together (20.1% and 20.0%, respectively). The highest rate of spousal abuse was found among remarried families (14.7%), while child and elder abuse was most prevalent among extended families (12.4% and 4.1%, respectively).</p><p><b>CONCLUSIONS</b>The findings suggested that although the prevalence of DV in Hunan was modest compared to Western countries, it remained a serious public health problem affecting over 1 in 10 households. Furthermore, the prevalence of various types of DV varied by geographic setting and family structure, suggesting that diverse geographic setting and family constellations carried different risk and protective features.</p>
