Chinese herbal property theory (CHPT) is the fundamental characteristic of Chinese materia medica different from modern medicines. It reflects the herbal properties associated with efficacy and formed the early framework of four properties and five flavors in Shennong's Classic of Materia Medica. After the supplement and improvement of CHPT in the past thousands of years, it has developed a theory system including four properties, five flavors, meridian entry, direction of medicinal actions (ascending, descending, floating and sinking) and toxicity. However, because of the influence of philosophy about yin-yang theory and five-phase theory and the difference of cognitive approach and historical background at different times, CHPT became complex. One of the complexity features was the multiple methods for determining herbal property, which might include the inference from herbal efficacy, the thought of Chinese Taoist School and witchcraft, the classification thinking according to manifestations, etc. Another complexity feature was the multiselection associations between herbal property and efficacy, which indicated that the same property could be inferred from different kinds of efficacy. This paper analyzed these complexity features and provided the importance of cognitive approaches and efficacy attributes corresponding to certain herbal property in the study of CHPT.

Chinese herbal property is the highly summarized concept of herbal nature and pharmaceutical effect, which reflect the characteristics of herbal actions on human body. These herbal actions, also interpreted as presenting the information about pharmaceutical effect contained in herbal property on the biological carrier, are defined as herbal property expressions. However, the biological expression of herbal property is believed to possess complex features for the involved complexity of Chinese medicine and organism. Firstly, there are multiple factors which could influence the expression results of herbal property such as the growth environment, harvest season and preparing methods of medicinal herbs, and physique and syndrome of body. Secondly, there are multiple biological approaches and biochemical indicators for the expression of the same property. This paper elaborated these complexities for further understanding of herbal property. The individuality of herbs and expression factors should be well analyzed in the related studies.

Objective The effect of angiotensinⅡ(AngⅡ) on cardiac hypertrophy were studied in SD rat with different ages. Methods Cardiocyte and cardiac fibroblasts in neonatal SD rat group and 12 months SD rat group were cultured in vitro. In each ages group, control MEM, angⅡ, angⅡantagonist(Losartan) and angⅡ+losartan were administrated respectively. 3 H leu incorporation into cardiocyte and 3 H TdR incorporation into cardiac fibroblasts were measured in neonatal rat group and 12 month rat group. To investigate the effect of cardiac fibroblasts on cardiocyte under the influence of angiotensinⅡ, the supernatant of cultured cardiac fibroblasts with angiotensinⅡ, the supernatant of cultured CBS with losartan and the supernatant of cultured cardiac fibroblasts with angiotensinⅡ and Losartan were added into cultured cardiocyte respectively. 3 H leu incorporation into cardiocyte were tested. Results 10 6 mol/L angⅡcan evidently augment 3 H leu incorporation into cardiocyte ( P

Eight mongrel dogs were involved in the investigation of sevoflurane effects on renal blood flow (RBF). After intravenous anesthesia and surgical preparation, RBF, MAP, HR, CVP, CO and SV were recorded as baseline. Sevoflurane was then administered to achieve end-tidal concentrations of 1, 2, 3 and 4% in succession. Following 20 mins equilibration at each concentration, and 30 mins after the termination of inhalation, the above parameters were measured repeatly for comparing. Results showed significant dose-related depressions of RBF, MAP, HR and CO with sevoflurane. RBF didn't reduce significantly until MAP decreased to 9.3kPa, with end-tidal concentration of sevoflurane no less than 3%, it didn't recover in step with improved hemodynamic parameters after sevoflurane withdrawal. This study indicates that sevoflurane may influence little on autoregulation of RBF, its dose-related cardiac depression may be responsible for the reduction of RBF.

Objective To study the effect of the combination of rivaroxaban and Xuesaitong injection on deep venous thrombosis (DVT) of lower extremity after spinal surgery.Methods The clinical data of 90 patients undergoing spinal surgery from May 2013 to May 2015 were retrospective analyzed.The patients were divided into two groups randomly: the treatment group and control group.Forty-five patients in treatment group were treated with rivaroxaban and Xueshuantong injection from 1 st day after surgery to one week after off-bed activity, and forty-five patients in control group were treated with rivaroxaban alone.The vessels of lower extremity were detected by doppler ultrasonography pre-surgery, 7-10d and 3 months post-surgery, then the rates of DVT and pulmonary embolism were statistically analysed.Results The DVT rate in treatment group was 8.89%(4 cases), which was significantly lower than 24.4% (11 cases) in control group (P<0.05).Conclusion The anticogulant effect of the combination of rivaroxaban and Xuesaitong injection is stronger than rivaroxaban alone.

Objective To study the efficacy of JueDuYin in the treatment of benign prostatic hyperplasia (BPH). Methods 120 cases were randomly recruited into a treatment group and a control group, with 60 cases in each group.The treatment group was given JueDuYin, one dosage per day, while the control group was administrated with Finasteride, 5mg per day. After three courses of twelve weeks' treatment, the indications of international prostate symptom score (IPSS), residue urine (RU), Qmax and total prostatic value (IPV) were observed. Results There was significant changes in the valve of IPSS,RU, Qmax for both groups after the treatment compared (P<0.05～0.01). The therapeutic effects of the treatment group was obvious better than the control group (P<0.05).

Objective To investigate the clinical outcomes of radical surgery for pancreatic body and tail tumors accompanied with sinistral portal hypertension (SPH).Method The clinicopathological data of 35 patients with pancreatic body and tail tumors accompanied with SPH operated from January 2004 to December 2014 were retrospectively analyzed.Results Of 35 patients,22 patients had body and tail pancreatic carcinomas,10 patients had malignant solid pesudopaillary tumors and 1 patients had a neuroendocrine tumor.All these patients developed splenomegaly and varices in the gastric fundus with normal hepatic function.The splenic vein pressure was (27.3 ±3.8)cmH2O (1 cmH2O =0.098 kPa),its average diameter was (1.3 ± 0.3) cm,and the speed of splenic vein blood flow was (8.9 ± 0.8) cm/s.Of the 35 patients with pancreatic body and tail tumors who underwent radical resectional operations,22 patients in addition underwent devascularization.There were 13 of these 22 patients who underwent pericardical devascularization and the remaining 9 underwent total or proximal gastrectomy.The main complications were pancreatic fistula (n =5,14.2％),intra-abdominal infection (n =4,11.5％),delayed gastric emptying (n =1,2.8％),lymphatic fistula (n =1,2.8％) and gastric perforation (n =1,2.8％).The post-complication morbidity rate was 34％.All these patients were followed-up for 6 to 60 months after operations.There was no upper gastrointestinal bleeding which occurred within 6 months of operation.Conclusion Multi-disciplinary treatment,complete preoperative evaluation,correct perioperative and individualized management enhanced efficacy in the surgical treatment of patients with pancreatic body and tail tumors with SPH.

AIM:To explore the effects of small interfering RNA(siRNA) targeting PCNA gene on nasopharyngeal carcinoma CNE2 cells growth and cycle.METHODS:Three synthesized siRNA targeting PCNA gene was transfected into CNE2 cells by using LipofectamineTM reagent.The PCNA mRNA and PCNA protein were detected by real-time polymerase chain reaction(RT-PCR) and immunohistochemical method.Inverted phase contrast microscope was used to determine the CEN2 cells growth before and after PCNA-siRNA transfected.Flow cytometry was used to observe the cell cycle.RESULTS:In CNE2 cells after PCNA-siRNA transfection,the expressions of PCNA mRNA and protein were down-regulated at different degree.Inhibition ratio of PCNA mRNA was 98.5%.Meanwhile,the cell cycle was suffocated at G0/G1 stage.CONCLUSION:The synthesized PCNA-siRNA effectively interferes nasopharyngeal carcinoma cells by down-regulating the expressions of the PCNA mRNA and its protein,therefore inhibits the growth of CNE2 cells.Future application of PCNA-siRNA in the gene therapy of nasopharyngeal carcinoma might be expected.
