Objective To investigate the significance of the serum levels of interleukin-10 (IL-10),IL-13,IL-15 of patients with chronic hepatic failure and the correlation between those inter- leukin levels and nosocomial infections.Methods The serum levels of IL-10,IL-13,IL-15 of 58 patients with chronic hepatic failure were measured by double antibody sandwich enzyme-linked immu- nosorbent assay at the time of admission and 2 weeks after admission.Results The serum levels of IL-15 and the propotion of IL-15/IL-10 and IL-15/IL-13 in patients with chronic hepatic failure group at the time of admission were significantly higher than those in healthy control group[(358.16?290.91) ng/L vs (38.55?21.49) ng/L,12.93?14.26 vs 1.10?0.55,98.55?97.5.5 vs 9.70?5.03,respectively,all P=0.000].Those in death group were significantly higher than those in improving group[(479.93v205.52) ng/L vs (244.51?236.29) ng/L,17.65?17.78 vs 8.53?7.98,130.69?115.50 vs 68.55?65.99,respectively,all P

Objective To explore the influence of cognitive-dual task on balance function and analyze the sensory strategy of balance maintained.Methods Form June,2015 to June,2016,34 healthy young people were randomly divided into control group(n=17)and obser-vation group(n=17).They were tested with the modified Clinical Test of Sensory Interaction on Balance(mCTSIB)on Neurocom Balance Manager,and retested two weeks later,while the observation group completed mental arithmetic cognitive task simultaneously.The center of gravity(COG)sway velocity and the comprehensive sway velocity were measured in both eyes open(EO)and eyes closed(EC)standing on firm or foam support.Results For the second test,The COG sway velocity decreased in the control group as EC standing on foam sup-port(t=2.535,P<0.05),while it increased in the observation group as EO standing on foam support(t=-2.220,P<0.05),and it was more than that in the control group(t=-3.128,P<0.01).The comprehensive sway velocity decreased in the control group(t=3.007,P<0.01),but increased in the observation group(t=-2.170,P<0.05),which was significantly different between two groups(t=-2.143,P<0.05).Conclu-sion Cognitive tasks may interfere balance function in healthy youth,especially in the condition of EO standing on foam support.Sensory re-source may preferer to meet the balance maintained during cognitive-dual tasks.

The roles of intermediate conductance Ca(2+)-activated K(+) channel (IKCa1) in the pathogenesis of hepatocellular carcinoma (HCC) were investigated. Immunohistochemistry and Western blotting were used to detect the expression of IKCa1 protein in 50 HCC and 20 para-carcinoma tissue samples. Real-time PCR was used to detect the transcription level of IKCa1 mRNA in 13 HCC and 11 para-carcinoma tissue samples. The MTT assay was used to measure the function of IKCa1 in human HCC cell line HepG2 in vitro. TRAM-34, a specific blocker of IKCa1, was used to intervene with the function of IKCa1. As compared with para-carcinoma tissue, an over-expression of IKCa1 protein was detected in HCC tissue samples (P<0.05). The mRNA expression level of IKCa1 in HCC tissues was 2.17 times higher than that in para-carcinoma tissues. The proliferation of HepG2 cells was suppressed by TRAM-34 (0.5, 1.0, 2.0 and 4.0 μmol/L) in vitro (P<0.05). Our results suggested that IKCa1 may play a role in the proliferation of human HCC, and IKCa1 blockers may represent a potential therapeutic strategy for HCC.

Objective To investigate the improvement effect and mechanism of marmesin on cognitive impairment in Alzheimer's disease(AD)mice.Methods Fifty mice were randomly divided into five groups:blank group,model group,low-and high-dose marmesin groups and donepezil(positive drug)group,with 10 mice in each group.After 21 days of continuous administration,except for the blank group,the mice in other groups were given intraperitoneal injection of scopolamine to establish the AD model.Network pharmacology was used to construct the protein-protein interaction(PPI)network of common targets of marmesin in the treatment of AD,and gene ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)enrichment analysis were performed to provide further research direction.The cognitive function of AD model mice was evaluated by Morris water maze,open field test and new object recognition test.Nissl staining was used to observe the damage of hippocampal neurons.The levels of acetylcholine(Ach),acetylcholine transferase(ChAT),acetylcholinesterase(AChE),reactive oxygen species(ROS),malondialdehyde(MDA)and catalase(CAT)in hippocampus of mice were detected by kit.The protein expression levels of interleukin 6(IL-6),interleukin 1β(IL-1 β),tumor necrosis factor α(TNF-α),nuclear factor E2-related factor 2(NRF2),silent information regulator homologous protein 3(SIRT3),Kelch-like ECH-associated protein 1(KEAP1),quinone oxidoreductase 1(NQO1)and heme oxygenase 1(HO-1)in hippocampus were detected by Western Blot.Results Compared with the model group,the latency of Morris water maze test was significantly shortened in the high-dose marmesin group,the time of entering the target area in the open field new object test and the movement distance in the central area of the open field were prolonged,the number of neurons in the hippocampal CA1 and CA3 regions was significantly increased,the levels of ChAT and Ach in the hippocampus were significantly increased,AChE level was significantly decreased,CAT level was significantly increased,ROS and MDA levels were significantly decreased,TNF-α expression level was decreased,SIRT3 and HO-1 expression levels were increased,and KE AP1 protein expression level was decreased,the differences being statistically significant(P＜0.05 or P＜0.01 or P＜0.001).Conclusion Marmesin can effectively improve the learning and memory impairment of AD mice,and its mechanism may be related to the activation of NRF2/SIRT3 signaling pathway,thereby alleviating oxidative stress level and neuroinflammation,and repairing cholinergic neuron function.

OBJECTIVEThis study aimed to investigate the depression status among high-risk pregnancy women, and to analyze its relevant social and psychological factors.

METHODSA total of 42 high-risk pregnancy women and 40 normal pregnancy women in a teaching hospital in Harbin city were followed up at time points of 32 - 36 weeks pregnancy, one week before labor, one week postpartum, and six weeks postpartum, respectively. During follow-up, the basic situation, social psychosocial factors of pregnancy women were collected and the depression of pregnancy women was measured by self-designed questionnaire and self-rating depression scale. The Edinburgh Postnatal Depression Scale (EPDS) was applied at timepoint of one week postpartum. Single factor analysis and the unconditional multivariate logistic regression were applied for analyzing the on the related social-psychosocial factors among high-risk pregnancy women.

RESULTSThe age of high-risk pregnancy women was (31.0±5.6), and the age of normal pregnancy women was (30.5±3.8) (t=0.169, P>0.05). The results showed that the depression rate in high-risk pregnancy women was 45.2% (19/42), which was 25.0% (10/40) in normal pregnancy women, the difference was significant (χ2=3.671, P=0.045). The depression rates at different time points were 30.9% (13/42), 42.9% (18/42), 23.8% (10/42), 26.2% (11/42) in high-risk pregnancy women respectively, and 25.0% (10/40), 15.0% (6/40), 20.0% (8/40), 17.5% (7/40) in the control group respectively, the difference of the depression rates among groups at one week before labor was significant (χ2=7.680, P<0.01), the difference among groups at 32-36 weeks pregnancy (χ2=0.133, P=0.80), at one week postpartum (χ2=0.174, P=0.79) and at six weeks postpartum (χ2=0.903, P=0.43) were not significant. At one week postpartum and six weeks postpartum periods, the EPDS depression rate were 12.5% (4/32), 30.4% (7/23) in case group respectively, 8.3% (3/36), 22.9% (8/35) in control group respectively, the difference were not significant (χ2=0.319, 0.416, P=0.573, 0.519). There were significantly associations between the depression mood of one week before labor and the depressive symptoms of six weeks postpartum in both groups (r=0.824, 0.677, both P values were <0.05). The risk factors for maternal depression among high-risk pregnancy women were not ready for production (OR=2.73, P<0.01) and fearing of childbirth safety (OR=2.89, P<0.01).

CONCLUSIONThe depression date of high-risk pregnancy was high, especially at the time point one week before labor. Risk factors of maternal depression among high-risk pregnancy were "not ready for production" and "fear of childbirth safety".

Objective To investigate the relationship between serum angiotensin converting enzyme (ACE) and angiotensinogen (AGT) and gestational hypertension syndrome (HDCP) and the risk factors of HDCP. Methods A total of 135 pregnant hypertensive patients (HDCP group) and 100 normal pregnant women as control check (CK) group were selected. Serum ACE and AGT levels were measured by ELISA, and correlation analysis was performed. The age and gestational age of the two groups, pre-pregnancy body mass index (BMI), parity, number of births, family history of hypertension, family history, education, and other general information, single factor analysis of risk factors for maternal HDCP, single factor regression analysis Statistically significant factors were all used for multivariate logistic regression analysis. Results The serum ACE level in the HDCP group (90.49±47.65) μg/L was significantly higher than that in the CK group (58.72±27.58) μg/L, P<0.05, the difference was statistically significant. The serum AGT level in the HDCP group was (64.57±19.71) μg/L was higher than CK group (58.22±18.64) μg/L, P>0.05, the difference was not statistically significant; single factor analysis showed; age, BMI, hypertension, family history of diabetes, ACE level was maternal (P<0.05), while gestational age, parity, number of births, and education were no significant differences in risk factors for HDCP (P>0.05). Multivariate analysis showed: age, BMI, history of hypertension and ACE. It was a risk factor for pregnancy-induced hypertension. Conclusion ACE levels are associated with HDCP. AGT levels are not associated with HDCP. Patients with a high age, high BMI, and hypertension history have an increased risk of gestational hypertension syndrome.

Objective To investigate the relationship between angiotensin converting enzyme (ACE) and angiotensinogen (AGT) gene expression, gene polymorphism and pregnancy-induced hypertension in Qinghai.

The frequency distribution of ACE I/ D polymorphic alleles I and D was different between HDCP group and CK group(P<0. 05). D allele frequency was higher in HDCP group than in CK group (

OBJECTIVE: To compare the clinical efficacy between acupuncture combined with cinesiotherapy cupping and acupuncture combined with conventional cupping for knee osteoarthritis (KOA) with stagnation and blood stasis syndrome, and to seek a better solution for KOA. METHODS: A total of 78 patients of KOA with stagnation and blood stasis syndrome were randomly divided into an observation group and a control group, 39 cases in each group (3 cases in the observation group and 2 cases in the control group lost contact). Both groups were treated with acupuncture at Neixiyan (EX-LE 4), Dubi (ST 35), Xuehai (SP 10), Liangqiu (ST 34), Heding (EX-LE 2), Zusanli (ST 36), Yinlingquan (SP 9), Yanglingquan (GB 34) and Xuanzhong (GB 39). Based on the acupuncture treatment, the control group was treated with conventional cupping. The No. 4 cupping glass was used for Xuehai (SP 10), Liangqiu (ST 34) and Fengshi (GB 31), while the No. 3 cupping glass was used for Yinlingquan (SP 9), while the cupping with appropriate size was used for points; the cupping glass was retained for 5 min. Based on the acupuncture treatment, the observation group was treated with cinesiotherapy cupping. The selection of acupoint and cupping glass was identical as the control group. The patients were instructed to perform knee flexion-extension, hip abduction-adduction, weight-bearing and other active exercise while cupping; the treatment was given once a day, 10 times as a course of treatment; totally three courses were given with an interval of 2 days between the courses. The patient's symptom scores, pain scores and knee function scores were recorded before and after treatment. The amount of joint effusion was measured by ultrasound; the level of interleukin-1 (IL-1), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) in joint effusion were measured by ELISA. RESULTS: After treatment, the total effective rate in the observation group was 94.4% (34/36), which was significantly higher than 86.5% (32/37) in the control group (<0.05). Compared before treatment, the symptom scores, pain scores, amount of joint effusion and the levels of IL-1, IL-6, TNF-α in joint fluid in both groups all were decreased after treatment, whereas the knee function scores were increased (<0.05). Compared with the control group, the symptom scores, pain scores, and the levels of IL-1, TNF-α and the amount of joint effusion all were significantly decreased, whereas the knee function scores were increased in the observation group (<0.05). The level of IL-6 in joint effusion was not significantly different between the observation group and the control group (>0.05). CONCLUSION The acupuncture combined with cinesiotherapy cupping could alleviate pain, improve joint function and reduce joint effusion, which is superior to acupuncture combined with conventional cupping.

BACKGROUNDWith the progress of perinatal medicine and neonatal technology, more and more extremely low birth weight (ELBW) survived all over the world. This study was designed to investigate the short-term outcomes of ELBW infants during their Neonatal Intensive Care Unit (NICU) stay in the mainland of China.

METHODSAll infants admitted to 26 NICUs with a birth weight (BW) < l000 g were included between January l, 2011 and December 31, 2011. All the data were collected retrospectively from clinical records by a prospectively designed questionnaire. The data collected from each NICU transmitted to the main institution where the results were aggregated and analyzed. Categorical variables were performed with Pearson Chi-square test. Binary Logistic regression analysis was used to detect risk factors.

RESULTSA total of 258 ELBW infants were admitted to 26 NICUs, of whom the mean gestational age (GA) was 28.1 ± 2.2 weeks, and the mean BW was 868 ± 97 g. The overall survival rate at discharge was 50.0%. Despite aggressive treatment 60 infants (23.3%) died and another 69 infants (26.7%) died after medical care withdrawal. Furthermore, the survival rate was significantly higher in coastal areas than inland areas (53.6% vs. 35.3%, P = 0.019). BW < 750 g and GA < 28 weeks were the largest risk factors, and being small for gestational age was a protective factor related to mortality. Respiratory distress syndrome was the most common complication. The incidence of patent ductus arteriosus, intraventricular hemorrhage, periventricular leukomalacia, bronchopulmonary dysplasia, retinopathy of prematurity was 26.2%, 33.7%, 6.7%, 48.1%, and 41.4%, respectively. Ventilator associated pneumonia was the most common hospital acquired infection during hospitalization.

CONCLUSIONSOur study was the first survey that revealed the present status of ELBW infants in the mainland of China. The mortality and morbidity of ELBW infants remained high as compared to other developed countries.
