AIM: To study the effects of Huoxue Huayu and Yiqi Wenyang compound prescription (composition; ginseng, radix astragali, plantaginis semen, lignum sappan, chuanxiong, salvia miltiorrhiza, radix aconiti lateralis preparata, bitter orange, cassia twig) of TCM on the congestive heart failure in rats. METHODS:The rats were given doxorubicin hydrochloride by intraperitoneal injection to establish the model of congestive heart failure and were randomly divided into control group, congestive heart failure model group, Xinbao treatment group ( XB treatment) and Huoxue Huayu and Yiqi Wenyang compound prescription treatment group (QXYTM treatment). Normal saline, liquid medicine Xinbao and liquid medicine Huoxue Huayu and Yiqi Wenyang compound prescription were administered respectively to four groups by gavage. Radioimmunoassay, semi - quantitative RT - PCR and flow cytometry methods were used to determine the expressions of plasma atrial natriuretic peptide ( ANP) , renal medulla aquaporin - 2 ( AQP2 ) and heat shock protein70 (HSP70) in congestive heart failure rats before and after treatment. RESULTS: In congestive heart failure rats treated with Huoxue Huayu and Yiqi Wenyang compound prescription, the cardiac output and left ventricle systolic pressure increased significantly, the left ventricular end diastolic pressure decreased, and the maximum ascending and declining rate of left ventricular pressure ameliorated, thus the hemodynamics was effectively improved. Meanwhile, the level of plasma cardionatrin decreased, the abnormal expression of renal medulla AQP2 was markedly restored, and the transcription and expression of HSP70 gene were also increased. CONCLUSION: Huoxue Huayu and Yiqi Wenyang compound prescription promotes the recovery of the pathogenetic conditions of congestive heart failure in rare. The mechanism may be in association with a decrease in plasma ANP level, correction of renal medulla AQP2 abnormal expression and enhancement of HSP70 expression.

ObjectiveTo compare the clinical characteristic and postoperative histopathological parameters in different prostate size and to assess the effect of prostate volume on histopathological outcomes in patients after laparoscopic radical prostatectomy. MethodsTwo hundred and sixteen patients from 2006 to 2011 who were proved prostatic carcinoma by biopsy and performed laparoscopic radical prostatectomy wewe retrospectively evaluated.All patients were divided into the small group ( < 30 ml,103 cases),intermediate group(30 -60 ml,71 cases) and large group ( >60 ml,42 cases) according to prostate volume.Clinical variables included age,body mass index (BMI),preoperative PSA level,prostate volume,percentage of positive needles,clinical stage,and biopsy Gleason score (GS).Histopathological parameters included pathological GS,upgrading or not compared to biopsy GS,pathological stage and surgical margins status.Preoperative clinical variables and postoperative histopatholgogical parameters were compared among the 3 prostate groups. ResultsPatients with smaller prostates had lower PSA levels than those with intermediate and larger prostates (P =0.000).They also had worse histopathological outcomes such as pathological GS ( P =0.034 ),upgrading of GS ( P =0.037 ),and pathological stage ( P =0.025 ).35.0% of patients in smaller prostate group had a positive surgical margin compare to 33.8% and 19.0% in intermediate and larger prostate groups,but there was no significant difference (P =0.152).ConclusionMen with smaller prostate may have more high-grade cancer and more advanced disease after laparoscopic radical prostatectomy.
4. Comparative studies on anti-inflammatory and analgesic activities of different fractions from Isatidis Radix
Chinese Traditional and Herbal Drugs 2014;45(17):2517-2521
Objective: To observe the anti-inflammatory and analgesic activities of the different fractions from Isatidis Radix. Methods: The anti-inflammatory effects were observed by a in vitro model of LPS-stimulated RAW264.7 macrophages, and the analgesic effects were evaluated by the writhing test and the tail-immersion test in mice. Results: The water extract, 30%, 50%, and 70% ethanol extracts of Isatidis Radix all had anti-inflammatory and analgesic activities. The 50% and 70% ethanol extracts were the main anti-inflammatory effective fractions. The water extract and 70% ethanol extract were the main analgesic effective fractions. Conclusion: Different fractions of Isatidis Radix all have anti-inflammatory and analgesic activities, and the 70% ethanol extract has stronger activities. The mechanism of the anti-inflammatory and analgesic activities of the 70% ethanol extract may be related to the inhibition of the release of TNF-α and PGE2 from macrophages.

Aim To observe the cardioprotection of chronic intermittent hypobaric hypoxia (CIHH) against ischemia/reperfusion injury in adult and young rats.Methods Adult and postnatal male Sprague-Dawley rats were divided randomly into four groups:control 28-day group (CON28),control 42-day group (CON42), CIHH 28-day treatment group (CIHH28), and CIHH 42-day treatment group (CIHH42). CIHH animals with maternal rats were put into a hypobaric chamber 2 days before birth to get 28 days and 42 days CIHH mimicking 3000 m altitude (P_B=525 mmHg,P_(O_2)=108.8 mmHg), 5 h daily, respectively.The control animals were kept in the same environment as CIHH rats with free access to water and food except hypoxic exposure. The isolated hearts were perfused in the Langendorff apparatus, undergoing 30 min global ischemia and 60 min reperfusion.Cardiac function was recorded continuously during the whole experiment. Parameters of left ventricular function included left ventricular developing pressure (LVDP), left ventricular end-diastolic pressure (LVEDP), maximal positive (+LVdp/dt) and negative (-LVdp/dt) velocity of left ventricular pressure, coronary flow (CF) and heart rate(HR).Results ① For adult rats, there was no significant difference in the parameters of left ventricular function between CIHH28 and CON28 groups. However, the recovery of cardiac function in CIHH42 rats was much better than that in CON42, including LVDP, LVEDP, ±LVdp/dt and CF (P<0.05). ② For young rats, the basic coronary flow (CF) in CIHH rats was significant higher than that in CON rats, while other parameters of cardiac function didn't change. The recovery of cardiac function in CIHH rats was much better than that in CON rats, including LVDP, LVEDP,±LVdp/dt and CF (P<0.05).Conclusion CIHH confers cardioprotection against ischemia/reperfusion injury in rat cardiomyocytes, which is predominant in CIHH42 group and significantly affected by the age of animals. Cardioprotective effects produce more easily in young rats by CIHH.

Objective:To explore and analyze the points-selection rules in acupuncture treatment of mammary gland hyperplasia (MGH) by data mining and statistical method. Methods:Clinical literatures about the treatment of MGH with acupuncture published in the recent 16 years were retrieved from Chinese Journal Full-text Database (CJFD) and established into a database by Excel. The SPSS 20 version software and Clementine 12.0 version software were adopted to analyze the frequency and association rules of points-selection in the treatment of MGH with acupuncture. Results:The top 3 points used most frequently in acupuncture treatment of MGH were Danzhong (CV 17), Taichong (LR 3) and Zusanli (ST 36); points from the Stomach Meridian of Foot Yangming and Liver Meridian of Foot Jueyin were most commonly used; the commonly selected points were predominantly distributed in thoracic and abdominal regions and lower limbs; emphasis on the combination use of local and distal points; of the specific points, the five Shu-Transmitting points were mostly used; association analysis showed that the associations among Taichong (LR 3), Danzhong (CV 17) and Zusanli (ST 36) were the most significant. Conclusion: The data mining results substantially accord with the general rules of acupuncture-moxibustion theories in traditional Chinese medicine, able to reflect the points-selection principles and features in acupuncture treatment of MGH and provide evidence for the points selection in the treatment of MGH in acupuncture clinic.

The chemical consitituents from cytotoxic fraction of the Callicarpa nudiflora extract were isolated and purified by a combination of HP-20 macroporous resin, silica gel and Sephadex LH-20 column chromatographies. The structures were elucidated on the basis of the spectroscopic data and comparison of their spectroscopic data with reported data. The cytotoxicity was evaluated by the MTT assay. The 50% and 70% EtOH elutions of EtOH-extract showed significant cytotoxic activities, leading to the isolation of twelve compounds, which were identified as luteoloside(1), lutedin-4'-O-β-D-glucoside(2), 6-hydroxyluteolin-7-O-β-glucoside(3), lutedin-7-O-neohesperidoside(4), rhoifolin (5), luteolin-7, 4'-di-O-glucoside (6), forsythoside B (7), acteoside (8), alyssonoside (9), catalpol(10), nudifloside(11), and leonuride(12). Compounds 3-6, 10 and 12 were isolated from this genus for the first time, and compound 9 was isolated from this plant for the first time. The cytotoxicity assay demonstrated that flavonoids 1-6, in various concentrations, showed monolithic proliferation inhibitory activities against Hela, A549 and MCF-7 cell lines. Compounds 3, 5 and iridoid glycoside 11 possessed higher cytotoxicacivities. In short, flavonoids are the main components of cytotoxic extract from C. nudiflora, while phenylethanoid glycosides are the predominant ingredient but inactive to cancer cell lines. In addition, the minor iridoid glycoside expressed weak cytotoxic activity.
