Objective: To study the effect of Shenxiong Xintong Pill(SXP) on cardiac hemodynamics. Methods: Parameters of cardiac hemodynamics were examined in anesthetic chest-opened dogs medicated with various doses of SXP. Results: After intraduodenal administration of SXP of 2.0g/kg, the coronary blood flow was raised, coronary resistance decreased, heart rate slowed and the left ventricular diastolic end pressure fallen in the dogs. No obvious changes were found in the contraction , works and ejection of left ventricle. Conclusion: The mechanism of SXP in relieving angina pectoris was probably related to the dilatation of coronary artery and increase of coronary flow with the increase supply of oxygen.

Objective To investigate the influence of psychological intervention in emotional disorder on blood pressure,lipids and glucose in hypertensive patients in community.Methods 599 hypertensive in community were divided to intervention group (n =302) and control group (n =297) by randomization.The control group received routine medication.Additionally the intervention group got another psychological intervention which lasted 6 months.An SCL-90 scale was adopted to evaluate patients'psychological change of mental health,blood sugar,low density lipoprotein cholesterol,total cholesterol,systolic pressure and diastolic blood pressure before and after treatment.Results Somatization,compulsion,interpersonal relationship,depression,anxiety,hostility and terror in intervention group((1.44±0.29),(1.78 ±0.39),(1.66±0.38),(1.63 ±0.48),(1.43 ±0.35),(1.37 ± 0.52) and (1.28 ± 0.41) respectively) had a lower score than control group ((2.01 ± 0.59),(2.04±0.68),(1.88 ±0.38),(1.84±0.59),(1.92±0.54),(1.61 ±0.53)and(1.60±0.50)).The differences were significant(P＜ 0.01).After intervention,blood glueose,low density lipoprotein,total cholesterol,systolic pressure,and diastolic pressure were ((4.65 ± 0.811) mmol/L,(2.97 ± 0.702) mmol/L,(4.86 ± 0.884)mmol/L,(134.11 ± 13.39)mm Hg(1 mm Hg =0.133 kPa) and (93.73 ±7.61)mm Hg respectively) and before intervention((5.09 ± 0.710) mmol/L,(3.23 ± 0.584) mmol/L,(5.36 ± 1.138) mmol/L,(150.13 ± 12.23) mm Hg and (89.64 ± 8.35) mm Hg respectively).The differences were significant (P＜ 0.05).Conclusion Cognitive behavioral therapy can improve community hypertension patients' physiology and psychology,which is good for blood pressure,lipids,glucose control.

The effects of Sonic hedgehog (Shh) signaling pathway activation on S-type neuroblastoma (NB) cell lines and its role in NB tumorigenesis were investigated. Immunohistochemistry was used to detect the expression of Shh pathway components-Patched1 (PTCH1) and Gli1 in 40 human primary NB samples. Western blotting and RT-PCR were used to examine the protein expression and mRNA levels of PTCH1 and Gli1 in three kinds of S-type NB cell lines (SK-N-AS, SK-N-SH and SHEP1), respectively. Exogenous Shh was administrated to activate Shh signaling pathway while cyclopamine was used as a selective antagonist of Shh pathway. S-type NB cell lines were treated with different concentrations of Shh or/and cyclopamine for different durations. Cell viability was measured by using MTT method. Apoptosis rate and cell cycle were assayed by flow cytometry. The xenograft experiments were used to evaluate the role of Shh pathway in tumor growth in immunodeficient mice. High-level expression of PTCH1 and Gli1 was detected in both NB samples and S-type NB cell lines. Cyclopamine decreased the survival rate of the three cell lines while Shh increased it, and the inhibition effects of cyclopamine could be partially reversed by shh pre-treatment. Cyclopamine induced the cell apoptosis and the cell cycle arrest in G(0)/G(1) phase, while Shh induced the reverse effects and could partially prevent effects of cyclopamine. Cyclopamine could also inhibit the growth of NB in vivo. Our studies revealed that activation of the Shh pathway is important for survival and proliferation of S-type NB cells in vivo and in vitro through affecting cell apoptosis and cell cycle, suggesting a new therapeutic approach to NB.

Objective To observe the safety and clinical efficacy of enhanced recovery after surgery in the perioperation period of hepatectomy.Methods 92 patients with primary hepatic cancer who underwent surgical resection in our hospital from December 2014 to May 2016 were divided into two groups,50 patients received well-organized and consecutive clinical interventions guided by ERAS.42 patients underwent traditional perioperative management.Results Compared with traditional group,ERAS group had reduced hospital cost [(40 633.12 ± 6 336.46) RMB vs.(46 139.23 ± 9 605.88) RMB,P ＜ 0.05],shorter postoperative hospital stay[(10.24 ± 1.6) d vs.(13.35 ± 4.86) d,P ＜ 0.05],earlier flatus and defecation [(33.34 ±6.01) h vs.(50.31 ± 3.53) h,P ＜ 0.05],and improved satisfaction rate for pain management[45/50(90％) vs.22/42(52.4％),P ＜ 0.05];while the postoperative adverse events and complications of the two groups showed no difference (P ＞ 0.05).Conclusion The application of ERAS in the perioperation period of hepatectomy is safe and effective,reducing hospital cost,postoperative hospital stay,improving satisfaction rate to pain management,and facilitating recovery in hepatic surgery.

Objective To compare the therapeutic efficacy of combined biliary stent and 125I seed intracavity irradiation with palliative surgery in the treatment of extrahepatic ductal cholangiocarcinoma.Methods A prospective analysis was conducted on 142 patients with cholangiocarcinoma who were treated in The First Affiliated Hospital of Bengbu Medical College from January 2012 to December 2015.There were 80 patients who underwent percutaneous biliary metal stenting combined with 125I particles implantation (the stenting-particle group) and 62 patients who were treated by palliative biliary drainage (the surgical group).The surgical group included R1 resection in 17 patients,R2 resection in 26 patients and biliary enteric drainage in 19 patients).The levels of jaundice,liver function,survival time,hospitalization time and hospitalization cost before and after therapy were analyzed.Results Jaundice was effectively alleviated in the two groups after a short period.The liver function in the 2 groups improved significantly at 1,3 and 6 months when compared with that before operation,(P ＜ 0.05).The average hospitalization time of the stenting-particle group and the surgery group were (16.5 ± 5.0) days and (25.5 ± 10.5) days,respectively,(P ＜ 0.01).The average hospitalization cost of the stenting-particle group and the surgery group were (39 622.0 ± 7 666.4) yuan and (59 562.0 ± 24 218.2) yuan,respectively,(P ＜ 0.05).The average survival time of the stenting-particle group and the surgery group were (12.2 ± 5.1) months and (12.69 ± 7.46) months,respectively,and the difference was not significantly different (P ＞ 0.05).Conclusions For patients with extrahepatic ductal cholangiocarcinoma who were not suitable for radical surgery,percutaneous biliary stenting combined with 125I seed brachytherapy effectively reduced jaundice,improved liver function,shortened average length of hospital stay and reduced average cost of hospitalization.When compared with palliative surgery,it was a minimally invasive,easy,safe and efficacious treatment,especially for elderly patients with poor physical conditions.

The effects of Sonic hedgehog (Shh) signaling pathway activation on S-type neuroblastoma (NB) cell lines and its role in NB tumorigenesis were investigated. Immunohistochemistry was used to detect the expression of Shh pathway components-- Patchedl (PTCH1) and Glil in 40 human primary NB samples. Western blotting and RT-PCR were used to examine the protein expression and mRNA levels of PTCH1 and Glil in three kinds of S-type NB cell lines (SK-N-AS, SK-N-SH and SHEPI), re-spectively. Exogenous Shh was administrated to activate Shh signaling pathway while cyclopamine was used as a selective antagonist of Shh pathway. S-type NB cell lines were treated with different concen-trations of Shh or/and cyclopamine for different durations. Cell viability was measured by using MTT method. Apoptosis rate and cell cycle were assayed by flow cytometry. The xenograft experiments were used to evaluate the role of Shh pathway in tumor growth in immunodeficient mice. High-level expres-sion of PTCH1 and Gill was detected in both NB samples and S-type NB cell lines. Cyclopamine de-creased the survival rate of the three cell lines while Shh increased it, and the inhibition effects of cyclopaminc could be partially reversed by shh pre-treatment. Cyclopamine induced the cell apoptosis and the cell cycle arrest in G0/G1 phase, while Shh induced the reverse effects and could partially pre-vent effects of cyclopamine. Cyclopamine could also inhibit the growth of NB in vivo. Our studies re-vealed that activation of the Shh pathway is important for survival and proliferation of S-type NB cells in vivo and in vitro through affecting cell apoptosis and cell cycle, suggesting a new therapeutic ap-proach to NB.

Objective:To discuss the quantitative evaluation of left ventricular systolic function in patients with light-chain amyloidosis (AL) by pressure-strain loop (PSL).Methods:Forty-six patients with clinically diagnosed as AL in the Affiliated Tumor Hospital of Zhengzhou University from January 2018 to December 2020 were selected as case group, and they were divided into 2 groups according to whether the thickness of interventricular septum and posterior wall at end-diastole was >12 mm; ①cardiac amyloidosis (CA) group (21 cases, the thickness>12mm); ②non cardiac amyloidosis (NCA) group (25 cases, the thickness≤12 mm). Twenty five healthy volunteers were selected as control group at the same time. Routine echocardiography was performed in all subjects.Two-dimensional dynamic images of the left ventricular apical two-chamber, three-chamber, and four-chamber views were collected for three consecutive cardiac cycles using two-dimensional speckle-tracking. A tracing analysis was conducted and blood pressure was entered on the off-line Echo PAC 203 software, and the left ventricular global longitudinal strain (GLS), peak strain time dispersion(PSD), global myocardial work index (GWI), global constructive work (GCW), global wasted work (GWW) and global work efficiency (GWE) were obtained. The differences of GLS, PSD and myocardial work (GWI, GCW, GWW, GWE) parameters were compared between groups, and Pearson correlation was used to analyze the correlations.Results:①Routine echocardiography: Compared with the control group and NCA group, inter-ventricular septum thickness (IVST), left ventricle posterior wall thickness (LVPWT), left ventricular mass index (LVMI), left atrial diameter (LAD), and E/e′ in CA group were increased, while left ventricular ejection fraction (LVEF) was decreased; ②Compared with the control group, GLS, GWI, and GCW in NCA group were decreased, while there were no statistically differences in GWE, PSD, and GWW between the two groups (all P>0.05); Compared with the control group and NCA group, GLS, GWI, GCW, and GWE were obviously decreased, while PSD and GWW were obviously increased in CA group.③ Correlation analysis showed that: the absolute value of GLS was positively correlated with GWI, GCW and GWE ( r=0.654, 0.695, 0.788; all P<0.001), and negatively correlated with GWW, and PSD ( r=-0.710, -0.625; all P<0.001). Besides, PSD had negative correlation with GWI, GCW and GWE ( r=-0.754, -0.653, -0.702; all P<0.001), and positive correlation with GWW ( r=0.676, P<0.001). Conclusions:PSL can quantitatively evaluate the left ventricular systolic function of AL patients, while the myocardial work parameters are conducive to evaluate the degree of cardiac involvement in the course of AL patients.
