To clarify the origin and development of the traditional Chinese medicine "Duhuo" and "Qianghuo" with medicinal literatures. Medical literatures of past dynasties were analysed and combined with the modern material. The "Duhuo" in Herbal writing Shen Nong Ben Cao Jing include traditional Chinese medicine "Duhuo" and "Qianghuo", "Qianghuo" was separated from "Duhuo" due to the distinguish of clinical application. The origin of "Qianghuo" is Notopterygium incisum and N. forbesii, However, The origin of "Duhuo" is very complex, Angelica pubescens f. biserrata as authentic "Duhuo" was used from Song Dynasty. "Qianghuo" was originated from "Duhuo".

To clarify the origin and application development of the traditional Chinese medicine " Zi-hua Qianhu" and " Qianhu", the medicinal literatures of past dynasties and modern researches were analysed. The plant Angelica decursivum was used as a substitute for traditional Chinese medicine "Angelica sinensis Radix" for a long historical period, it is used incorrectly for traditional Chinese medicine "Qianhu" due to origin research in modern times. The plant origin of "Qianhu" is Peucedanum praeruptorum. There are significant differences in clinical applications and chemical composition of the two drugs. The same efficacy description of "Zi-huaQianhu" and "Qianhu" could not stop "Zi-huaQianhu" used as "Qianhu" in practical application. Therefore, we need to further research for the plant A. decursivum, delimit its medicinal attribution.

OBJECTIVE: To investigate the inhibition effects of Tianshen Yizhi Recipe (TSYZR), a compound traditional Chinese herbal medicine, on decreased expression of nicotinic acetylcholine receptor (nAChR) and the neurotoxicity as well as lipid peroxidation induced by beta-amyloid peptide (Abeta) in human SH-SY5Y neuroblastoma cells. METHODS: The SH-SY5Y cells were treated by a certain concentration of TSYZR, and then exposed to Abeta(25-35). Methyl thiazolyl tetrazolium reduction assay was carried out to understand the influences of the drugs on cellular viability. Expressions of nAChR subunits (alpha3 and alpha7) at protein and mRNA levels were detected by Western-blotting and reverse transcription polymerase chain reaction, respectively. Lipid peroxidation was measured by thiobarbituric acid to observe the capacity of antioxidant of the drugs. RESULTS: TSYZR at a safe concentration could increase alpha7 protein in the cells, inhibit decreased expressions of alpha3 and alpha7 nAChR subunit proteins, prevent lower expression of alpha7 mRNA in SH-SY5Y cells induced by Abeta, reduce the neurotoxicity and lipid peroxidation resulting from Abeta, but had no significant effect on the lower expression of alpha3 mRNA. CONCLUSIONS: TSYZR can up-regulate the expression of alpha7 nAChR subunit protein and prevent decreased expressions of nAChRs and neurotoxicity as well as lipid peroxidation induced by Abeta. This drug may play an important therapeutic role in treatment of Alzheimer disease.

Eight compounds from six Chrysanthemum morifolium cv. 'Hangju' were determined and multivariate statistics, including principle component analysis (PCA) and partial least squares discriminate analysis (PLS-DA) were used to investigate the potential damaging effect of sulfr-fumigating process. Meanwhile, S, Mn, Fe, Cu, Pb were also detected by using ICP-MS and ICP-OES. In this study, dramatic chemical changes were found that the contents of flavonoid aglycones remarkably increased while those of glycosides and hydroxycinnamoylquinic acids were significantly reduced. The PCA score plots showed six samples were clearly classified into the non-fumigated and sulfur-fumigated types. And according to VIP > 1, the most important chemical markers were luteolin, apigenin and luteolin-7-O-glucoside which indicated that the extracted three components might have a marked effect on the discrimination among different group samples. And then, it was found that the residue of sulfur of SHJ were significantly higher than NHJ (P < 0.05). The established approach was applied to rapidly discriminate sulfur-fumigated HJ with combining the quantitative chemical analysis and multivariate statistical analysis, and then the result will provide some evidence to evaluat the quality of HJ and control its processing.

Osteoarthritis (Osteoarthritis, OA) is a common clinical degenerative joint disease with increased incidence rate in recent years. Animal experiment is one of the important ways to explore pathogenesis and treatment of OA, while induced animal model is the most important part in animal experiment. Intra-articular injection of drugs is a classical method for establishing animal model of OA. Choose of animal should follows the principle of correlation, appropriateness and practicability, injections should perform in accordance with experimental purposes and subject, detections means and evaluation methods also should corresponding to experimental reality. The gold standard of OA animal model and intra-articular injections has not build, need further study.

OBJECTIVETo explore and analyze the feasibility of Community Health Service Center(CHSC)-based HIV prevention and intervention in China.

METHODSData on case finding and case management indexes were collected from 42 CHSCs in 8 cities from November, 2011 to December, 2012, and complemented by questionnaires to investigate the willingness to accept community-based HIV services among health care providers and the service targets.

RESULTSDuring November, 2011 and December, 2012, 6 729 person-times HIV tests were carried out among MSM in the cooperation between CHSCs and CBOs, and 235 HIV positives were found. A total of 40 CHSCs among 42 have conducted HIV rapid tests. The sample sources were broad and the HIV screening positive detection rate from high-risk populations in key divisions of CHSCs 0.66% (38/5 769) was higher than that in outreach high-risk populations 0.41% (15/3 623) and people receiving physical check 0.31% (20/6 532). HIV positive detection rate in CHSCs was higher 0.4% (96/23 609) than that in conventional medical institutions 0.1% (11 870/9 644 944) and newly found positives among the confirmed positives was a little lower 73.7% (56/76) than conventional programs 80.1% (8 038/10 039). The case follow-up and CD4(+) T cell testing rates in CHSCs were 100.0% (1 046/1 046) and 99.1% (1 037/1 046), respectively. The testing cost was 6.1 RMB per person on average, and the cost of 1 case found positive was 2 727.3 RMB on average. Among 361 service providers, 68.1% (246)and 91.4% (330) service providers were willing to be involved in AIDS response and support HIV service in local CHSCs. Among 755 service targets including people who seek health care in key divisions of CHSCs, MSM, and high-risk populations in local communities, 77.3% (348), 73.9% (173) and 78.1% (57) were willing to accept free HIV tests in local CHSCs.

CONCLUSIONThe effect of case finding and case management in CHSCs was good and the cost of conducting HIV tests and finding new cases were relatively low, meanwhile, most of the service provides in CHSCs and service targets support HIV service in local CHSCs. The future CHSC-based HIV prevention and intervention was feasible.

To investigate the influence of Anxin granules combined with tirofiban on acute myocardial infarction (AMI) Patients after elective percutaneous coronary intervention (PCI). One hundred and twenty AMI patients were randomly divided into treatment group and control group. The patients in the two groups were all given Tirofiban 30mins before PCI . The treatment group was added Anxin granules 30 mins before and after PCI. Tissue factor (TF) and von willebrand factor (vWF) were tested at 6 hours after operation. Syndromatology alteration of traditional Chinese medicine (TCM) and bleeding complications were observed at 4 weeks after operation. Both TF and vWF at 6 hours after operation of the treatment group was lower than the control group significantly (P < 0.01), while the condition of myocardial ischemia at 90 mins after operation of the treatment group was better than control group with significance. The syndromatology alteration of TCM especially spontaneous perspiration and hypodynamia of the treatment group were improved significantly compared to control group 4 weeks after operation. All patients in both groups had no bleeding complications and thrombopenia. The study suggests that Anxin granules combined with tirofiba can improve the clinical efficacy and the endothelial function of AMI patients after PCI with no increase in bleeding events.

OBJECTIVETo investigate the association between catecholamine-beta-adrenoceptor (beta-AR)-adenosine 3', 5'-monophosphate (cAMP) system and long-term prognosis in patients with chronic heart failure (CHF).

METHODSThe study population comprised 73 patients with CHF (EF: 23% +/- 10%) with a mean follow-up of 3.8 +/- 1.9 years. Plasma levels of norepinephrine (NE) were measured using high performance lipid chromatography, beta-adrenergic receptor density (Bmax) and the content of cAMP in peripheral lymphocytes were calculated using 3H-dihydroalpneolo as ligand and competitive immunoassay, respectively. Deaths due to cardiovascular events within the follow-up period were registered.

RESULTSThe total mortality was 64.7%, 57.4% of which was for cardiogenic (worsening heart failure: 32.4%; sudden death: 25.0%). In the cardiogenic death group, plasma levels of NE and epinephrine (E) (3.74 nmol/L +/- 0.09 nmol/L and 3.17 nmol/L +/- 1.0 nmol/L) and the contents of peripheral lymphocyte cAMP (3.64 pmol/mg protein +/- 1.4 pmol/mg protein) were significantly increased as compared with the survival group (2.68 nmol/L +/- 0.07 nmol/L, 2.41 nmol/L +/- 0.24 nmol/L and 2.73 pmol/mg protein +/- 0.9 pmol/mg protein, respectively, all P < 0.01). In the sudden death group, plasma levels of NE and E (5.01 nmol/L +/- 0.06 nmol/L and 4.13 nmol/L +/- 0.08 nmol/L) were significantly increased as compared with the worsening heart failure group (2.49 nmol/L +/- 0.07 nmol/L and 2.33 nmol/L +/- 0.8 nmol/L, all P < 0.001) and to the survival group (2.68 nmol/L +/- 0.07 nmol/L and 2.41 nmol/L +/- 0.14 nmol/L, all P < 0.01). The incidences of sudden death were 0%, 75%, and 100% (chi(2) = 16.018, P < 0.01) in patients with plasma NE < 2.5 nmol/L, NE 2.5 nmol/L - 4.5 nmol/L, and NE > 4.5 nmol/L, respectively. In the worsening heart failure group, the content of peripheral lymphocyte cAMP (4.46 pmol/mg protein +/- 0.18 pmol/mg protein) was significantly increased compared with the sudden death group (2.39 pmol/mg protein +/- 0.9 pmol/mg protein, P < 0.001) and to the survival group (2.73 pmol/mg protein +/- 1.1 pmol/mg protein, P < 0.001). The worsening heart failure death occurences were 5.0%, 72.2%, and 100% (chi(2) = 14.26, P < 0.01) in patients with a content of peripheral lymphocyte cAMP < 2.5 nmol/L, cAMP 2.5 nmol/L - 4.5 nmol/L, and cAMP > 4.5 nmol/L, respectively. Bmax in peripheral lymphocyte was not significantly different (P > 0.05) among the sudden death, worsening heart failure, and survival groups in CHF patients.

CONCLUSIONSPlasma levels of catecholamine increase significantly, and Bmax and the contents of cAMP in peripheral lymphocytes decrease significantly in patients with CHF. High plasma catecholamine levels may be associated with sudden death, and high intralymphocyte cAMP content may be associated with worsening heart failure in CHF patients.

Objective: To explore the predictors in patients of paroxysmal atrial fibrillation (AF) recurrence after radiofrequency catheter ablation (RFCA). Methods: A total of 142 PAF patients received RFCA in our hospital from 2013-03 to 2016-03 were studied. The patients were divided into 2 groups: Recurrence group, n=46 and Non-recurrence group, n=96. Clinical data was compared between 2 groups and AF recurrent predictors were studied by single and multivariate Logistic regression analysis. Based on quartiles of uric acid (UA) level, the patients were categorized in another set of 4 groups: Q1 group, UA<259 μmol/L, n=33, Q2 group, UA 259-320 μmol/L, n=37, Q3 group, UA 321-380 μmol/L, n=37 and Q4 group, UA>380 μmol/L, n=35. The influence of UA on AF recurrence was measured by Kaplan-Meier test, the predictive value of UA combining metabolic syndrome (UA+MS) on AF recurrence was studied by ROC curve analysis. Results: The BMI, diabetes, MS, AF duration, CHADS2 score, creatinine, UA and BNP were different between Recurrence group and Non-recurrence group, all P<0.05. Logistic regression analysis indicated that AF duration (OR=1.02,95% CI 1.01-1.03, P=0.002), UA level (OR=1.01, 95% CI 1.00-1.01, P=0.046) and MS (OR=4.73, 95% CI 1.36-16.45, P=0.014) were the independent predictors for AF recurrence. UA quartile analysis indicated that gender, BMI, MS, creatinine, LVEF and the incidence of AF recurrence had signifcant discrepancy by different UA levels, all P<0.05. ROC curve showed that the predictive values for UA+MS in AF recurrence had the sensitivity at 80.4%, specificity at 74.1% (AUC 0.79±0.04, 95% CI 0.71-0.89, P=0.0001), for UA in AF recurrence had the sensitivity at 73.9%, specificity at 57.2% (AUC 0.66, 95% CI 0.56-0.76, P=0.02); UA+MS had the higher predictive value than UA alone, P<0.05. Conclusion: Both UA and MS were related to AF recurrence, high UA level combining MS had certain predictive value for AF recurrence in PAF patients after RFCA.
