Traditional Chinese medicine industry is China's strategic emerging industry with great potential for self-innovation. Traditional Chinese medicine industry has successively experienced four stages which are the foundation (laying stage), the core status (establishing stage), the modern system (exploring stage), and the modernization system (constructing stage). Throughout the evolution of the self-innovation in traditional Chinese medicine industry, it presents distinct characteristics which we can explore the beneficial enlightenment.

OBJECTIVETo observe changes of plasma polypeptide hormone levels in rats with gastric ulcer after exposure to intense noise, and to discuss their mechanism.

METHODS80 Wistar rats were used in the study. Plasma levels of rat gastrin (GAS), motilin (MTL), osteocalcin (BGP), substance P (SP), neurotensin (NT) and somatostatin (SS) in rats were measured by radioimmunoassay.

RESULTS(1) In non-noise-exposure but with gastric ulcer group, the plasma MTL [(160.70 +/- 40.34) pg/ml] and BGP [(27.63 +/- 13.13) pg/ml] levels on 10 d after gastric ulcer model operation were remarkably higher than those in control group [(89.21 +/- 49.94) pg/ml, (9.10 +/- 1.38) pg/ml respectively] (P < 0.05 and P < 0.01), while the GAS level was remarkably descended [(107.00 +/- 21.75) vs (158.48 +/- 20.92) pg/ml] (P < 0.01). (2) In noise-exposure but without gastric ulcer group, the plasma MTL [(312.80 +/- 207.42) pg/ml] and BGP [(17.76 +/- 12.33) pg/ml] levels on 10 d were also significantly increased as compared with the control group (P < 0.01 and P < 0.05 respectively), while the GAS levels didn't change. (3) In noise-exposure + gastric ulcer group, the areas of gastric ulcer on 10 d and 40 d after noise and operation [(15.33 +/- 7.26) and (15.11 +/- 12.45) mm(2) respectively] were significantly larger than those of the control [(8.22 +/- 6.66), (3.67 +/- 9.90) mm(2)] (P < 0.05). The plasma MTL levels on 10 d and 40 d [(244.44 +/- 68.11) and (191.20 +/- 60.50) pg/ml respectively] were higher than those in control group [(160.70 +/- 40.34) and (93.10 +/- 52.90) pg/ml respectively] (P < 0.01).

CONCLUSIONIntense noise exposure may make the rat gastric ulcer worsened and induce negative effect on healing of it. The gastrointestinal endocrine would be disturbed by combined effect of intense noise exposure with gastric ulcer in rats.

OBJECTIVETo assess the antihypertensive effect and safety on medicine named 'Beijing Hypertensive No. 0' in a three-year treatment of primary hypertension.

METHODSA community-based intervention study was conducted. The antihypertensive effects and adverse events were observed.

RESULTS4000 patients with primary hypertension were randomly divided into two groups with 1529 patients treated with 'Beijing Hypertensive No. 0' and 976 patients treated with other antihypertensive drugs, among which 946 and 853 patients in the two groups completed the three-year study. After treatment, the systolic blood pressure decreased 13 mm Hg and 7 mm Hg while diastolic blood pressure decreased 8 mm Hg and 4 mm Hg in the 'No. 0' group and controlled group respectively. After three years of treatment, 90.0% and 79.5% in the 'No.0' group and in the control group had reached the BP 'fulfillment criteria', which were much higher than the baseline data. Side effects occurred in 33/1274 (2.6%) cases during three years' treatment with most commonly seen as dizziness, headache, palpitation and weakness. No serious adverse reactions occurred. There were some positive effects after treated by 'No. 0', including 0.13 mmol/L decrease of TC, 0.70 mmol/L decrease of LDL-C and an average 0.12 mmol/L increase of HDL-C. All of these changes were statistically significant. There were also opposite effects as 0.13 mmol/L increase of TG, 0.24 mmol/L increase of K+, and 0.88 mmol/L increase of Na+ on average, which were also statistically significant.

CONCLUSIONCompared with the conventional treatment, this treatment of 'Beijing Hypertensive No.0' was more convenient, safe and effective in treating mild to moderate primary hypertension in the community.

Objective To compare the cost-effectiveness of two anti-hypertensive therapy regimens,Compound anti-hypertensive tablets and other common anti-hypertensive agents,in the treatment program of Primary Hypertension.Methods We conducted a cost-effectiveness analysis based on a community trial.Two communities'primary hypertensive patients were enrolled to receive different therapy drugs:Compound anti-hypertensive tablets(Group A)or other common anti-hypertensive agents(Group B).Blood pressure,medicine used,and adverse drug reactions were observed and recorded for one year,and then costeffectiveness ratio of the two groups and incremental ratio were calculated.We considered a 30%drug price fluctuating load to make the sensitivity analysis.Results 2505 cases were enrolled with 1529 cases in group A and 976 cases in group B.The cost-effectiveness ratios were 418.1 and 1057.7 for Group A and B respectively while the incremental cost-effectiveness of Group B vs.Group A was 19 202.2.The results were insensitive to variation in the costs of drugs over clinically reasonable ranges.Conclusion Compound anti-hypertensive tablets appeared to be relatively cost-effective when compared to common drugs for the treatment of primary hypertension.

OBJECTIVETo study the application of cluster analysis in micrangium detection in malignant nasal and paranasal sinus tumor.

METHODSMicrovessel density (MVD) counting and cluster analysis were used to detect the micrangium in patients with malignant nasal and paranasal sinus tumor to assess the association between the malignancy and MVD.

RESULTSAccording to cluster analysis, the MVD counting could be clustered into two groups, and the MVD showed significant differences between the tumor tissues, adjacent normal tissue and the control group (P<0.01), a result consistent with that by analysis of variance of the MVD.

CONCLUSIONCluster analysis can be used in clustering of MVD counting in malignant nasal and paranasal sinus tumor to simplify MVD counting, and offers an important analytic method for micrangium analysis in tumors.

OBJECTIVE: To explore the cause, the clinical manifestation and the management of peripheral vascular complications after cardiac catheterization. METHODS: Clinical data of patients with peripheral vascular complications were analyzed retrospectively. RESULTS: Of the 4,531 patients, 122 (2.7%) had peripheral vascular complications, including local hematoma (86 cases, 1.90%), pseudoaneurysm (15 cases, 0.33%), arteriovenous fistula (8 cases, 0.18%), femoral venous thrombosis (5 cases, 0.11%), excessive hemorrhage (5 cases, 0.11%), femoral arterial thrombosis (2 cases, 0.04%), and femoral nerve malfunction (1 case, 0.02%). All complications were relieved after conservative therapy except that one case needed surgery. CONCLUSION Peripheral vascular complications are associated with anticoagulation, diabetes, and hypertension. Prognosis of overwhelming complications is good, as long as patients are treated timely and appropriately.

OBJECTIVE: To observe the changes and significance of plasma CD40L and pregnancy-associated plasma protein-A (PAPP-A) in acute coronary syndrome (ACS) patients after percutaneous coronary intervention (PCI) operation. METHODS: According to the occurrence of primary heart events or restenosis 6 months after the PCI, 68 patients were divided into the ACS group and the stable angina pectoris (SAP) group. Plasma CD40L and PAPP-A after the PCI operation were measured and compared. Thirty-six patients underwent repeated angiography after the PCI. Their baseline and follow up angiograms were compared by quantitative coronary angiography to assess the incidence of restenosis. RESULTS: CD40L and PAPP-A after the PCI operation were higher in the ACS group than that in the SAP group.The group having primary heart events within 6 months had higher level of PAPP-A after the PCI. The group having restenosis 6 months had higher level of PAPP-A after the PCI. The change of later loss index of coronary artery lumen diameter was correlated with PAPP-A level after the PCI. CONCLUSION CD40L and PAPP-A were higher in the ACS group, indicating the possible mechanism by which CD40L facilitates the plaque rupture via up-regulating the PAPP-A expression.Plasma PAPP-A level after the PCI possibly for cases the occurrence of primary heart events or restenosis within 6 months.
