Objective To analyze unsafely factors of elderly alimentary tract hemorrhage patients,strengthen nursing safety, assure nursing quality, improve patients' satisfaction and avoid adverse events happen to our bestMethods 223 elderly alimentary tract hemorrhage patients were collected from January to December in 2009, and safety factors, corresponding precaution have been made meanwhile.Days in hospital, recurrence of bleeding and passing rate of basic nursing and satisfaction rate of patients and incident of safety problems were compared with those 201 peering patients collected in 2008.Results Of all the physical factors, "suffering chronic disease in elderly patients" is most and accounts for 85.4%.Of all the psychological factors, "low economical status" is most and accounts for 54%. "Less communication between nurses and patients and inadequate instruction" is most (67%) of environmental and nurse staff factors.Average days in hospital were reduced in 2009 than in 2008 [(9.3 ±0.35)d vs(11.5 ±0.50)d, t =52.887, P ＜0.01].Passing rate,satisfaction rate were improved and bleeding recurrence rate were decreased, compared with those in 2008 (P ＜0.05).Conclusions It will gain better nursing efficacy through analyzing security issue carefully, finding out the disadvantage factor influencing patients' security and adopting effectve nursing safety control strategy.

OBJECTIVETo observe the effects of conventional therapy combined with Kanlijian (KLJ) on exercise tolerance, quality of life and frequency of heart failure aggravation in patients with chronic heart failure (CHF).

METHODSSixty CHF patients differentiated as sufferring from the syndrome of Xin-Shen Yang deficiency were included in the study and randomly assigned at the ratio of 2:1 into the KLJ group (n = 39) and the control group (n = 21). All the patients were treated with conventional therapy of Western medicine, but to those in the KLJ group, KLJ was medicated additionally one dose daily with 24 wks as one therapeutic course. The efficacy on TCM syndrome and changes of scores on TCM syndrome were observed after treatment. The indexes, including 6-minute walking distance (6MWD), quality of life (QOL, accessed by LHFQ scoring), NYHA grade, hemodynamic indexes and reducing/withdrawal rate of diuretic and digoxin before and after treatment were recorded and compared. Also the frequency of re-admission due to aggravation of heart failure in one year's time were observed.

RESULTS(1) The efficacy on TCM syndrome, improvement on scores of TCM syndrome, therapeutic effects on 6MWD, QOL, and NYHA grade in the KLJ group were superior to those in the control group. (2) Hemodynamic indexes after treatment, left ventricular fractional shortening (LVFS) and E peak/A peak (E/A), between the two groups had no significant difference, while left ventricular ejection fraction (LVEF) was increased significantly in the KLJ group, but with no obvious change in the control group. (3) The reducing/withdrawal rate of diuretic and digoxin in the KLJ group was significantly higher than that in the control group. (4) The 1-year frequency of re-admission significantly decreased in the KLJ group.

CONCLUSIONThe adjuvant treatment of KLJ on the basis of Western conventional therapy can significantly improve CHF patients' exercise tolerance, quality of life and cardiac function, reduce the dosage of diuretic and digoxin needed, and decrease the re-admission frequency due to aggravation of heart failure.

Objective To explore the effect of specific antagonist of estrogen-related receptor alpha——XCT790 on tumor growth, weight, liver index(LI), spleen index(SI) and kidney index (KI) in the diffe-rent models of tumor -bearing mice.Methods The H22 ascitic and solid tumor-bearing mice models were established , then mice were ran-domized into five groups , including model group (20%DMSO), control group(cyclophosphamide:CTX 30 mg· kg -1), experimental -L,-M,-H groups(XCT790:2,4,6 mg· kg -1).The samples were obtained in 24 h after continuous intraperitoneal administration of drug or solvent to mice for 7 d.The ascitic volume and tumor weight were measured .The ratios of LI,SI,KI were calculated.Results The ascitic volume of mice in model group, control group,and experimental -L,-M,-H groups were (6.17 ±3.04),(3.28 ±1.62),(3.60 ±1.67),(4.67 ±2.57), (4.73 ±2.66 ) mL; comparing between control group , experimental -L group and model group,the differences were significant(all P<0.01).In H22 solid tumor -bearing mice, the tumor weight of mice in model group, control group, experimental -L,-M,-H groups were (2.53 ±0.39),(1.25 ±0.45),(1.27 ±0.61),(1.14 ±0.56),(1.24 ±0.39) g with significant difference com-pared with model group ( all P<0.05 ) .LI,SI and KI had no statistically significant differences in ascitic or solid tumor-bearing groups(all P>0.05 ) .Conclusion XCT790 had anti -tumor effect on H22 tumor-bearing mice without influences on ratios of liver ,spleen and kidney.

To further reveal the risks of heroin abuse to human body, and to determine the injuries of oxidation, peroxidation and lipoperoxidation induced by nitric oxide and other free radicals to heroin abusers, we determined and compared plasma values of lipoperoxides (LPO), nitric oxide (NO), vitamin C (VC), vitamin E (VE), β-carotene (β-CAR) and erythrocyte values of LPO, superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) in 114 heroin abusers and 100 healthy volunteers. Using linear regression and correlation as well as stepwise regression and correlation, we also analyzed the effect of the abusing duration, and daily abusing quantity on the above-mentioned biochemical parameters in the heroin abusers. The results showed that, compared with the healthy volunteer groups, the average plasma values of LPO, and NO, and the average erythrocyte value of LPO in the heroin abuser group were significantly increased (P＜0.0001), and the average plasma values of VC, VE, and β-CAR and the average erythrocyte values of SOD, CAT, and GSH-Px were significantly decreased (P＜0.0001). Analysis of linear regression and correlation showed that with prolonged heroin abusing and with increased daily quantity in the heroin abusers, the plasma values of LPO, and NO, and the erythrocyte value of LPO were gradually increased (P＜0.001), whereas the plasma values of VC, VE, and β-CAR and the erythrocyte values of SOD, CAT, and GSH-Px were gradually decreased (P＜0.001). Analysis of stepwise regression and correlation indicated that the plasma values of NO, VC and VE were closely correlated with the abusing duration and daily abusing quantity. These results indicate that the balance between oxidation and antioxidation in the heroin abusers was seriously disturbed, and the injuries induced by nitric oxide and other free radicals, through oxidation, peroxidation and lipoperoxidation to the bodies of heroin abusers exacerbated. It is therefore necessary that in abstaining from heroin dependence, the heroin abusers should acquire sufficient quantities of antioxidants such as VC, VE and β-CAR.

OBJECTIVETo study the effects of post-discharge formula (PDF) for preterm infants, breast milk (BM) and term infant formula (TF) on increase rates of body weight, length and head circumference in preterm and low-birth-weight infants (PLBWIs) from discharge to 3 months after birth, and to provide a reference for the choice of feeding pattern for PLBWIs.

METHODSA total of 407 PLBWIs discharged from the newborn departments of ten hospitals in Guangzhou City and Foshan City in Guangdong Province, China were chosen for this study. According to feeding pattern, they were assigned to three groups: PDF-fed (n=258), BM-fed (n=58) and TF-fed (n=91). Their body weight, length and head circumference were measured at 3 months after birth, and the increase rates of growth indices relative to baseline values (at birth) were calculated and compared.

RESULTSAt 3 months after birth, the PDF-fed group had significantly greater body weight, length and head circumference than the BM-fed and TF-fed groups (P<0.05). The increase rates of body weight and length were significantly higher in the PDF-fed group than in the BM-fed and TF-fed groups (P<0.05).

CONCLUSIONSCompared with those fed with BM and TF after discharge, the PDF-fed PLBWIs have higher increase rates of body weight and length and show greater body weight and length at 3 months after birth. However, further study is needed to investigate the long-term effects.

Databases including CNKI,Wan Fang,CBM,VIP,PubMed and Cochrane Library were searched to collect qualified researches,and the quality of articles was evaluated according to scales. Meta-analysis including subgroup analysis was performed by using Rev Man 5. 3 software and Meta-regression test was performed by using Stata 12. 0 software. All of these methods were used to systematically evaluate the safety and clinical efficacy of Qili Qiangxin Capsules in treatment of ischemic heart failure under two circumstances( with or without syndrome differentiation). A total of 22 randomized controlled trials( RCTs) involving 1 942 patients were included,with generally low quality. RESULTS: of Meta-analysis showed that as compared with the routine Western treatment alone,additional use of Qili Qiangxin Capsules could improve the clinical efficacy( RR = 1. 21,95%CI[1. 16,1. 27],P<0. 000 01) in treatment of ischemic heart failure,with its combined effect of syndrome differentiation group greater than that of non-syndrome differentiation group( P= 0. 03,I~2= 78. 9%),Meta-regression( sig = 0. 9,P = 0. 057); left ventricular ejection fraction( WMD = 7. 28,95% CI[5. 18,9. 38],P<0. 000 01),with combined effect of syndrome differentiation group greater than that of non-syndrome differentiation group( P= 0. 01,I2= 83. 2%),Meta-regression( I~2= 81. 09%,R2= 29. 08%,sig = 0. 47,P = 0. 029); 6-minute walk test( WMD = 33. 20,95%CI[24. 70,41. 70 ],P < 0. 000 01); left ventricular end diastolic diameter( WMD =-4. 61,95% CI[-5. 38,-3. 84 ],P <0. 000 01); left ventricular end diastolic volume( WMD =-34. 43,95%CI[-38. 81,-30. 05],P< 0. 000 01); and left ventricular end systolic volume( WMD =-9. 60,95% CI[-13. 16,-6. 05],P < 0. 000 01). Adverse effects were reported in 11 patients taking Qili Qiangxin Capsules and in 20 patients with routine treatment group,tolerable in both groups. None of the patients had obvious abnormality in liver and kidney function. Qili Qiangxin Capsules were effective and safe in the treatment of ischemic heart failure,which can further improve clinical efficacy as compared with routine treatment alone. Qili Qiangxin Capsules with syndrome differentiation showed more significant effects than those without syndrome differentiation,indicating better efficacy of clinical syndrome differentiation. However,these conclusions still need to be verified with more high-quality and large-sample literature.

"Kidney essence" is a profound concept in the theory of traditional Chinese medicine. But its biological basis is unknown until now, resulting in the therapeutic effects of traditional Chinese drugs on reinforcing kidney for supplementing essence hard to be evaluated. This study aimed, to explore the potential biological basis and mechanism of traditional Chinese drugs of reinforcing kidney for supplementing essence on diseases related to deficiency of kidney essence through network pharmacology analysis on the intersection of targets of drugs and diseases. The targets for ingredients in Rehmanniae radix praeparata (RRP), Polygoni multiflori radix praeparata (PMRP) and Polygonati rhizome (PR) were gathered from TCMSP and TCMID database. Osteoporosis, Alzheimer's disease, anemia, infertility and oligospermia targets were collected from OMIM and DisGeNET database. Drug-compound-target-disease (DCTD) network was established with Cytoscape 3.6.1 software, then Clue GO and DAVID database was used to acquire the annotation about GO terms and signaling pathways. Natural aging mice, an acknowledged syndrome model of deficiency of kidney essence, and RRP were used to verify the predictive targets by Western blot analysis. All animal experiments were conducted in accordance with the international guidelines and regulations for the care and use of animals. DCTD network showed that the intersection of drugs and diseases included 175 common targets. After topology analysis, 71 key were screened out targets which were associated with GO annotation exhibited that biological processes (including transcription regulation, RNA metabolism regulation, and DNA-dependent transcription regulation), cell composition (including nuclear lumen, organelle lumen, and membrane closure lumen), molecular function (including transcription regulation, transcription factor activity, and enzyme binding), and signaling pathway (including peroxisome proliferator-activated receptor alpha (PPARα), mitogen-activated protein kinase (MAPK), hypoxia-inducible factor 1 (HIF-1), erythropoietin (EPO) and other signaling pathways. In natural aging mice, the expressions of HIF-1α, growth factor receptor-bound protein 2 (GRB2), MAPK3, signal transducer and activator of transcription 5A (STAT5A), transcription factor AP-1 (JUN) and proto-oncogene c-Fos (FOS) in EPO pathway were significantly decreased. RRP significantly reversed the decrease of the above targets. Above all, these results indicated that the therapeutic effects of traditional Chinese drugs of reinforcing kidney for supplementing essence on deficiency of kidney essence may be related to the regulation of nuclear transcriptional activity and EPO signaling pathway.
