Objective To investigate the relationship between primary TCM syndromes and heart rate variability in hypertension, evaluate the development of disease. Methods 182 hypertension patients were recruited in accordance with the standard of hypertension. According to the Chinese medicine dialectical criteria, these patients were further divided into 5 groups, namely, hyperactivity of liver-fire group, phlegm-dampness retention group, blood stasis group, hyperactivity of Yang due to yin deficiency group and Qi and blood deficiency group. Another 60 healthy people were recruited as a control group. 24h Holter was adopted to monitor heart rate variability. Results Analysis of TCM syndromes and heart rate variability, anger on inflammation group had positive relation with SDNN, RMSSD, LF, HF and TP(r were respectively 0.161,0.372, 0.223, 0.281, 0.301);Phlegmy wet resistance groups had positive relation with SDNN, HRV triangular index, VLF, LF, VLF/HF, LF/HF, LFnorm.(r were respectively 0.175, 0.211, 0.174, 0.262, 0.159, 0.264, 0.263);blood stasis group had negative relation with LF/HF, LFnorm(r were respectively-0.185、-0.018).Yang due to yin deficiency group had negative relation with SDNN, RMSSD, VLF, LF.(r were respectively -0.204, -0.161,-0.184,-0.197);Qi and blood deficiency group had negative relation with SDNN, SDANN, RMSSD and HRV triangular index, VLF, LF, LFnorm, and had positive relation with HFnorm(r were respectively-0.353,-0.348,-0.258, -0.303, -0.268, -0.361, -0.352, 0.267). Conclusion Hypertension patients with different type of TCM syndromes had different characteristics of autonomic nerve functional disorders, which both reflected the important pathological changes of TCM syndromes and had close relation with the course of hypertension, providing objective basis for clinical diagnosis of syndrome differentiation.

Objective To investigate the expression and significance of COX-2 and VECF in NHL Methods The expression of COX-2 and VECF in 28 cases of NHL was detected by immunohistochemistry, and 22 patients with benign lymphadenopathy were chosen as controls. Results Positive rates of COX-2 and VEGF were 82.1 %(23/28) and 78.6 %(22/28) in NHL respectively, significantly higher than that in the control (P <0.01). The expression rate of COX-2 was positively correlated with that of VEGF in tissues of NHL (χ~2 =10.50, P<0.01). Conclusion The expression of COX-2 and VEGF are high in NHL COX-2 and VEGF might have a common induction pathway, and selective COX-2 inhibitor might be a new drug for treatment of NHL in the future.

Objective To explore the efficacy and the prognostic factors of docetaxel combined with gemcitabine for patients with recurrent or metastatic breast cancer.Methods Forty-six patients with recurrent or metastatic breast cancer received docetaxel combined with gemcitabine regimen (docetaxel 75 mg/m2,intravenous drip,dl ; gemcitabine 1000 mg/m2,intravenous drip,dl,d8; The regimen was repeated every threeweeks for 3-6 cycles).The response rate (RR) was evaluated after 2 cycles,and the overall survival (OS)and progress-free survival (PFS) were recorded.Single factor chi square test and multivariate Cox proportion hazard model were used to evaluate the relationship between clinic pathologic features and RR,OS.Results All patients completed 3-6 cycls chemotherapy.The overall response rate was 56.5％ (26/46) and disease control rate was 82.6％ (38/46),with 4 patients of complete remission (8.7％),22 patients of partial remission (47.8％),12 patients of stable disease (26.1％) and 8 patients of progressive disease (17.4％).The median OS of 46 patients was 16.0 months (95％ CI:6.5-25.5 months) and PFS was 8.0 months (95％ CI:6.2-9.8 months).Single factor analysis showed that age,menopausal status,PS score,the number of metastasis had correhtions with RR (P ＜ 0.05) ; Cox proportion hazard model also showed that age,menopausal status,PS score,the number of metastasis had correlations with OS,and were the prognostic factors (P ＜0.05).The most frequent treatment-related adverse events were myelosuppression,gastrointestinal reaction,rash,alopecia,fatigue,and were tolerable (Ⅰ-Ⅱ level).Condusion Docetaxel combined with gemcitabine is effective and safe in the treatment of recurrent or metastatic breast cancer.Age,menopausal status,PS score and the number of metastasis are the prognostic factors for efficacy of docetaxel combined with gemcitabine regimen.

Objective To evaluate clinical treatment method and efficacy of newly diagnosed acute promyelocytic leukemia (APL),and analyze the relevant factors about the long-term survival.Methods The clinical data of 48 patients with newly diagnosed APL were analyzed retrospectively.All of them used alltrans retinoic acid (ATRA) combined with anthracycline as induction remission therapy.After induction remission,ATRA combined with chemotherapy was used as consolidation therapy,and ATRA,arsenic trioxide and conventional chemotherapy alternated as maintenance therapy.Short-term efficacy was analyzed.Patients were followed up,and the rates of overall survival (OS) and disease-free survival (DFS) were analyzed.Long-term efficacy was analyzed by COX proportional hazards regression models univariate analysis.Results The complete remission (CR) rate was 87.5％(42/48) in all 48 patients with APL.The time from treatment beginning to CR was (30.7 ± 4.6) d.Age was the only factor affecting the rate of CR.The rates of 1-year,3-year and 5-year OS were (87.5 ± 4.8)％,(85.4 ± 5.1)％ and (78.3 ± 6.7)％ in 48 patients with APL.The rates of 1-year,3-year and 5-year DFS were (97.6 ±2.4)％,(93.9 ±4.2)％ and (89.5 ± 5.9)％ in 42 patients with CR.COX proportional hazards regression model univariate analysis result showed that the patient' s age,gender,lactate dehydrogenase,diffuse intravascular clotting,risk stratification and bone marrow abnormalities promyelocyte ratio had no correlation with the rate of DFS (P ＞0.05).Conclusions ATRA combined with anthracycline as induction remission therapy,after induction remission ATRA combined with chemotherapy as consolidation therapy,and ATRA,arsenic trioxide and conventional chemotherapy alternated as maintenance therapy can get a higher rate of CR and long-term survival in patients with newly diagnosed APL.It is worthy of clinical application.

A novel method for analysis of three active components curcumin, demethoxycurcumin and bisdemethoxycurcumin in Curcuma longa L. was developed by HPLC coupled with electrochemical detection. Three curcuminoids were well separated on a C18 column and detected with high sensitivity. A mobile phase containing acetonitrile and 10 mM Na2HPO4-H3PO4 (pH 5.0) (50:50, v/v) was used. Good linearity was obtained in the range of 0.208-41.6, 0.197-39.4, and 0.227-114μM for curcumin, demethoxycurcumin and bisdemethoxycurcumin respectively. The limit of detection reached up to 10 ? 8 M, which was lower than that by UV detection. The relative standard deviations (RSDs) ranged from 1.06%to 1.88%for intra-day precision and from 4.30%to 5.79%for inter-day precision, respectively. The proposed method has been applied in real herb sample and recoveries ranging from 86.3%to 111%were obtained.

AIM:To study the effects of N-palmitoylethanolamide ( PEA) on the anxiety-and depression-like behaviors of the mouse model induced by restraint stress , and to explore the possible mechanism of anxiolytic and antide-pressant effects of PEA .METHODS:The mice were intragastrically treated with 2.5, 5 and 10 mg/kg of PEA for 21 con-secutive days once daily .Thirty min after intragastric administration , the mice ( except the normal control group ) were placed in the glass tube to accept 4-h chronic restraint stress for 21 d.After the last administration , the mice were submit-ted to the forced stress test and the open field test (OFT) to observe the effects of PEA on the depression-like behaviors. The cumulative immobility time was recorded during the 4-min interval in the forced swimming test ( FST) or during the 5-min interval in the tail suspension test (TST).The elevated plus maze (EPM) test was used to investigate the effect of PEA on the mouse anxiety-like behaviors , and the water maze method was used to investigate the learning and memory abi-lities, spatial orientation and cognitive function of mice .After the behavior tests , the serum was collected and the hippo-campus was removed . The serum contents of adrenocorticotropic hormone ( ACTH ) , cortisol ( CORT ) and 5-hydroxytryptamine (5-HT) in the hippocampus were detected by ELISA .The changes of acetylcholinesterase ( AChE) ac-tivity in the hippocampal homogenate was measured by spectrophotometry .RESULTS:Compared with model group , in the FST or TST, the immobility time in the mice treated with PEA at 2.5~10 mg/kg and fluoxetine was significantly reduced . In the OFT, the total locomotion distance and total movement time were increased significantly in the mice , but only 10 mg/kg PEA and fluoxetine increased the numbers of rearing .In the EPM test , the percentage of the time spent in open arms, the entries into open arms and the total locomotion distance in 4 arms in the mice were significantly increased .In wa-ter maze test , PEA at 5 and 10 mg/kg and fluoxetine significantly shortened the latency to find the security zone in the mice, and PEA at 10 mg/kg and fluoxetine obviously shorten the swimming distance .Compared with model group , PEA at 10 mg/kg and fluoxetine reduced the mouse serum levels of ACTH and CORT , and the adrenal index , increased the 5-HT content and decreased the AChE activity in the hippocampus .CONCLUSION:PEA produces antagonistic effects on an-xiety-and depression-like behaviors in the mice induced by restraint stress .Its specific mechanism may be related to the re-gulation of the hypothalamic-pituitary-adrenal axis function by increasing the 5-HT level in hippocampus , thus participating in the regulation of central cholinergic system .

AIM:To investigate the in vitro killing effect of adenovirus-mediated herpes simplex virus thymidine kinase gene(HSV-TK) driven by hypoxic response element(HRE) on hepatoma cell line HepG2.METHODS:Recombinant adenoviral vector Ad-HRE-TK was constructed with HSV-TK under the control of HRE using AdEasy system.Then Ad-HRE-TK was transfected into hepatoma cell line HepG2 and the cells were cultured under normoxic or hypoxic conditions.After treated with GCV for 3 d,the sensitivity to GCV of HepG2 was measured by MTT method.RESULTS:Over 95% HepG2 cells infected with Ad-HRE-TK cultured under hypoxic condition were killed when the MOI was 100 and the concentration of GCV was 50 mg/L.On the contrary,no killing effect of GCV was observed in cells cultured under normoxic condition.CONCLUSION:HRE promotes the expression of HSV-TK specifically under hypoxic condition and induces the specific killing effect of GCV.

Objective: To observe the effect of edaravone combining ulinastatin on brain protection in patients of type A aortic dissection (AAD) after total arch replacement. Methods: A total of 60 AAD patients with total arch replacement in our hospital from 2014-09 to 2016-01 were prospectively studied. Based on peri-operative application of edaravone and ulinastatin, the patients were divided into 2 groups: EU group: 1) the patients received ulinastatin 300000 U/8h and edaravone 0.5mg/Kg/12h from administration to 3 days post-operation, 2) during cardiopulmonary bypass, the patients received ulinastatin 300000 U/2h and edaravone 0.5mg/Kg; Control group, the patients had no such treatment.n=30 in each group. The following items were observed:①operative condition;②blood levels of speciifc brain injury markers as S-100 and neuron speciifc enolase (NSE) at different time points: beginning of surgery (T0), opening aorta clamp (T1), right after cardiopulmonary bypass (T2), entering ICU (T3), 24h post-operation (T4) and 3 days post-operation (T5); ③post-operative condition. Results:①Durations of operation, cardiopulmonary bypass, cardiac arrest and bilateral antegrade selective cerebral perfusion (BACP), the frequency of BACP and UACP (unilateral antegrade selective cerebral perfusion), the lowest rectal temperature and blood levels of S-100, NSE at T0 were similar between 2 groups.②Compared with Control group, EU group had decreased S-100 and NSE from T1 to T5,P<0.05.③The in-hospital and ventilation time, frequency of PND and TND, the patients with CSS score≥16 before discharge and the in-hospital death rate were similar between 2 groups,P>0.05. Conclusion: Edaravone combining ulinastatin had brain protective effect in AAD patients after total arch replacement;it may reduce blood speciifc brain injury markers while the clinical signiifcance should be further investigated.
