Objective To investigate the regulatory effect of Xinchuan capsules on the excessive activation of neuroendocrine with heart failure.Methods The heart failure animal model was built up using dogs by intravenous pumping of sodium pentobarbital.Water extract of Xinchuan capsules was given through duodenum.Indicators relating to the excessive activation of neuroendocrine changes of each group were observed.Results Xinchuan capsules could significantly increase the density of beta receptors of failure myocardial cells and lower the level of plasma norepinephrine and epinephrine,and remarkbly decrease the activity of plasma angiotensin converting enzyme.This played the similar role as the positive control drug metoprolol plus captopril.Conclusion Xinchuan capsules have the regulatory effect on the excessive activation of neuroendocrine with heart failure.TCM treatment for heart failure should not only target the functional disorder of the heart dominating blood circulation and vessels,but also the functional disorder of the heart stores the spirit,that is uneasy mental state.

Objective To investigate the feasibility of spleen-and splenic vessels-preserving laparoscopic distal pancreatectomy for the treatment of pancreatic cystic tumor of body and tail.Methods The clinical data of a female patient with pancreatic cystic tumor of body and tail who was admitted to the Sun Yat-Sen Memorial Hospital of the Sun Yat-Sen University in March 2013 were retrospectively analyzed.Spleen-and splenic vesselspreserving laparoscopic distal pancreatectomy was determined as the optimal therapeutic method according to the physical examination and the results of computered tomography scan.Laparoscopic or open operation combined with distal pancreatectomy and splenectomy would be carried out as a candidate choice once it is hard to separate the splenic artery and vein from distal pancreas or to control the serious vessels hemorrhage.The patient was followed up by outpatient examination every 1 to 3 months up to March 2015.Results Spleen-and splenic vessels-preserving laparoscopic distal pancreatectomy was finished successfully.The operation time and volume of intraoperative blood loss were 192 minutes and 50 mL,respectively.The patient took out-of-bed for activity at postoperative day 1 without complications.The multiple severe microcystic pancreatic adenoma was confirmed by postoperative pathological examination,with a maximum diameter of 3.5cm.The leakage tube was removed at postoperative day 5.The levels of serum amylase at postoperative day 1,3,5 were normal.The patient was discharged at postoperative day 8 and got regular follow-up without bleeding,pancreatic fistula,infection and a symptom of epigastric pain or discomfort.Conclusion Spleen-and splenic vessels-preserving laparoscopic distal pancreatectomy has advantages of less traumas,faster postoperative recovery and a preservation of normal splenic function,deserving clinical application.

Objective: To obtain cDNA of chalcone synthase (CHS, EC 2.3.1.74) involved in the flavonoid/isoflavonoid biosynthesis pathway. Methods: The partial sequence of CHS in Lycium barbarum (LyCHS) was successfully cloned by RT-PCR and using a sequence homology strategy, and the bioinformation analysis was carried out. Results: The cDNA fragment of CHS gene was 1148 bp in length, which encoded a protein of 382 amino acids with the predicted relative molecular weight of 4.168 × 104. The estimated isoelectric point (pI) of the putative protein is 6.22. According to the amino acid sequence and structural analysis, it showed that this protein contained one conserved active site, namely chalcone and stilbene synthases active site. Subcellular localizations of LyCHS proteins were likely in the cytoplasm. The secondary and tertiary structures of LyCHS were abundant in α-helixs (166) and random coils (126), while were less in β-turns (25) and extended strains (65). Phylogenetic analysis showed that the genes of LyCHS were closely related to CHS in Solanum pinnatisectum, S. tuberosum, and Lycopersicon esculentum. The sequences had been registered in GenBank with the accession numbers JQ964237. Conclusion: The present results provide the foundation for the next study of CHS gene about its expression and function in L. barbarum.

BACKGROUND: There are pressure sensors in carotid-sinus, which are very sensitive to blood pressure regulated by ions and play an important role in the regulation of blood pressure. But it is yet not very clear how different ions regulate the blood pressure through pressure sensors in carotidsinus.OBJECTIVE: To observe the effect of different ions at various concentrations outside the carotid-sinus.DESIGN: Self-control experiment.SETTING: Preclinical Experiment Center, Fourth Military Medical University of Chinese PLA.MATERIALS: The experiment was accomplished in the Preclinical Experiment Center, Fourth Military Medical University of Chinese PLA from December 2000 to June 2001. Totally 18 New Zealand pure strain rabbits were provided by the Aninal Experimenting Center of Fourth Military Medical University of Chinese PLA. They were standard grade Ⅱ, of either gender and body mass was (2.0±0.2) kg.METHODS: The rabbits were divided into Na+, K+ and Ca2+ groups according to random numbers, and each group consisted of 6 rabbits. After anaesthesia, tracheal intubatton was performed on the rabbit, and bilateral carotid arteries were separated with carotid-sinus separated on one side and vessel intubatton performed in the other side for blood pressure measurement. Then various concentrations of Na+, K+ and Ca2+ ions were added outside the carotid-sinus with the pipette to make the carotid-sinus completed immersed in the ion solutions. The basal blood pressure and the peak value after ions addition were recorded respectively.MAIN OUTCOME MEASURES: The basal blood pressure and the peak value after ions addition.RESULTS: After Na+ (0.15, 1.5 mol/L) was added the blood pressure was(97±12), (83±17) mm Hg. It was decreased significantly compared with the basal value (106±14), (105±12) mm Hg (t=2.946, P ＜ 0.05). K+ (0.4 mol/L)decreased the blood pressure significantly [(106±12), (64±13) mm Hg, (t=13.496, P ＜ 0.01)], but other concentrations of K+ were not effective. Ca2+(0.07 mol/L) increased the blood pressure to (113±16) mm Hg compared with the basal value (103±12) mm Hg (t=-3.627, P ＜ 0.01).CONCLUSION: Na+, K+ and Ca2+ regulate the blood pressure by acting on the carotid-sinus directly. High concentrations of Na+ and K+ possess the effect of decreasing the blood pressure, while high concentrations of Ca2+increases it, which may be an important mechanism of blood pressure regulation.

Objective:To observe the therapeutic effect and toxicity of local Kanseran injection in combination with chemotherapy in advanced NSCLC patients.Methods:A total of 18 cases was recruited in this study. After desensitization,Kanseran injection was injected into tumor mass through fibrobronchoscope,2 mg every time,once per week. Meanwhile,MVP regimen was administered.Results:Of the 18 patients,1 was completely relieved,7 cases were partially relieved. The response rate was 44.4%. After treatment,when examined by fibrobronchoscope the tumor masses of 15 patients became smaller. The main side effects were fever,alopecia and gastrointestinal reaction,which were mild and tolerable.Conclusion:Local Kanseran injection into tumor mass in conjunction with chemotherapy is effective and safe in the treatment of advanced NSCLC patients with bronchus obstruction.
