Objective To observe the clinical efficacy of acupoint application with Xiong Bi Tie in treating unstable angina pectoris. Method Sixty eligible subjects with unstable angina pectoris were randomized into a control group (treated with basic Western medication) and a treatment group (intervened by the basic Western medication plus acupoint application with Xiong Bi Tie), 30 cases in each group. The symptoms of unstable angina pectoris, syndromes and signs of traditional Chinese medicine (TCM), and cardiogram were recorded, and the clinical efficacies were also observed. Result In comparing the improvement of angina pectoris, the treatment group was better than the control group, with a statistical significance (P<0.05). From the perspective of TCM syndromes and signs, the efficacy of the treatment group was significantly better than that of the control group (P<0.05). Regarding the cardiogram, the total effective rate was 76.7% in the treatment group versus 50.0% in the control group, and the difference was statistically significant (P<0.05). Conclusion Acupoint application with Xiong Bi Tie can significantly improve the angina symptoms and cardiogram result of unstable angina pectoris (blood stagnation caused by qi deficiency syndrome), and it’s safe and easy-to-operate.

Objective To explore the role of HPV16 and p53 protein in the pathogenesis of tumors of nasal cavity and sinus of Chinese people. Methods The expression of HPV16 and p53 in 58 tumor samples of nasal cavity and sinus was detected by immunohistochemistry. Results There was no p53 expression in inverted pipillomas(IP). HPV16 infection rate in IP was 62.5%. The positive rate of p53 protein in the malignant tumors and IP with atypical hyperplasia was 56.0% and 44.4%, respectively, and HPV16 infection rate in the both tissues was 24.0% and 66.7%, respectively. The positive rate of p53 and HPV16 simultaneous expression in IP with atypical hyperplasia were 33.3%, which was higher than that in the malignant tumors and IP without atypical hyperplasia. Conclusion The high-risk HPV16 infection may be primary cause of IP. p53 gene mutation may be close relation with the pathogenesis of nasal cavity and sinus malignant tumors. HPV16 and p53 may have synergic effect in the malignant transformation of nasal cavity and sinus benign tumors.

0.05). Conclusion The p53 gene mutation has close relation with nasal malignant tumor , and may has no related to the pathogenesis of IP possible.

There is a high prevalence of gastric cancer in China,but most of the patients are diagnosed at advanced stages,when chemotherapy is regarded as an important component of the multimodal treatment.Chemotherapy has demonstrated advantages over best suppor-tive care in prolonging survival and improving quality of life.Over the past 40 years,the clinical responses of two or three-drug combination chemotherapy regimens have been accepted,and 5-fluorouracil,cisplatin and epirubicin have been most frequently used in gastric cancer.Recently,the therapeutic effects of advanced gastric cancer treated by new regimen consisted of docetaxel,irinotecan,oxaliplatin and capecitabine have been further enhanced.The molecular targeted agent,cetuximab and bevacizumab,combined with chemotherapy,would be more promising therapeutic regimens in the treatment of advanced gastric caner.

ObjectiveTo detect the content of vascular endothelial growth factor（VEGF）in aqueous humour and in vitreous of patients with proliferative diabetic retinopathy（PDR）．MethodsEnzyme linked immunosorbent assay（ELISA）was used，which is one of the basic methods of protein quantitative analysis．ResultsThe VEGF levels in aqueous humour of PDR（mean level 398．6 pg/ml）were higher than those of the controls（mean level 106.5 pg/mlP＜0.05）．The VEGF levels in vitreous of the four PDR（mean level 1395.2 pg/ml)were higher than those in aqueous humour of the four PDR(P＜0.05，Primer t test）．The increased VEGF level in vitreous was positively correlated with the level in aqueous humour．In the normal group，the mean value of VEGF in the vitreous was 64.6 pg/ml．In comparison with that of 1140.4 pg/ml in the PDR group，there was a significant difference between the two groups （P＜0.05，Primer t test）．ConclusionVEGF might play an important role in the pathogenesis of neovascularization of PDR．

Liver ischemia reperfusion injury is a common pathophysiological process in hepatic surgery,which is the consequence of multiple mechanisms such as oxidative stress,inflammatory reaction,apoptosis,and autophagy and so on.However,the molecular mechanisms behind these processes have not been completely elucidated,the current treatment of liver I/R injury is merely supportive care,and thus new therapeutic strategies are needed.The recent studies indicate that the ischemic precondition and pharmacological precondition may protect the liver against hepatic ischemiareperfusion injury.It will be an important clinical significance of further studying its molecular mechanisms and protective strategies.

ObjectiveTo evaluate the therapeutic effect of encircling constriction of superficial femoral vein in the treatment of primary deep venous insuficiency(PDVI).MethodsFrom Jan.2004 to Jun.2011,187 patients( 196 lower extremities)with primary deep venous insufficiency were treated with encircling constriction of venous wall at the first pair of superficial femoral venous valve pulse superficial varicose stripping.Results The 183 limbs in 176 patients were followed-up from 7 months to 8 years,with a mean period for 63.5 months.Ninety-four point one percent of the patients were followed up (176/187).Clinical symptomatic improvement achieved in 87.4％ ( 160/183 ) of the lower extremities.There was 2.2％ ( 4/183 ) of recurrence of the varicose vein,9.3％ ( 17/183 ) of light edema,8％ ( 2/25 ) of recurrence of ulcer.ConclusionEncircling constriction of superficial femoral vein is an effective method in the treatment of primary deep venous valve insufficiency.

BACKGROUND:Potential mechanisms of scar formation and scar prevention strategies have become more important in current medical research. Scar assessment scales have the potential to contribute to better evaluation of scar properties in both research and clinical diagnosis. OBJECTIVE: To summarize the literatures addressing scar prevention and clinical assessment. METHODS: A computer search of CNKI database from 2000 to 2014, PubMed database from 1975 to 2014 and Foreign Medical Journal Ful-Text Service Database from 2000 to 2014 was performed using the keywords of scar, prevention, treat, cicatrix, assessment, measure in Chinese and English to retrieve articles related to scar prevention strategies and scar assessment scales. Totaly 39 articles meeting the inclusive criteria were included in result analysis. RESULTS AND CONCLUSION: During wound healing, the unbalance between colagen anabolism and katabolism can lead to the formation of pathological scar. Prevention and treatment of pathological scars should be combined, and early intervention was used in wound healing. General scar assessment scales include Vancouver Scar Scale, Visual Analog Scale, Patient and Observer Scar Assessment Scale, Manchester Scar Assessment Scale, Stony Brook Scar Assessment Scale, al of which have the potential to contribute to better evaluation of scar properties in both research and clinical diagnosis.

Objective To discuss the application of bare-stent“chimney”technique in treating aortic dissection associated with left common carotid rupture, and to evaluate its therapeutic effect. Methods The clinical data of 7 patients with aortic dissection accompanied with left common carotid rupture, who were admitted to Qinghai Provincial People’s Hospital during the period from February 2012 to March 2014 to receive endovascular isolation operation treatment with bare-stent “chimney” technique, were retrospectively analyzed. When the rupture of aortic dissection was occluded with covered-stent, the left common carotid rupture was isolated with “chimney”bare-stent to reconstruct the blood flow of left common carotid artery. CT angiography was performed 2 weeks after the operation to check if there was any complication such as endoleak, stent migration, etc. Results The technical success rate of endovascular isolation operation was 100%. No type I endoleak occurred. The patients were followed up for 1-13 months, the covered stent in the aorta was in good position, and the “chimney” bare-stent in the left common carotid artery was patent. No complications such as endoleak, stent migration, etc. occurred. Conclusion Bare-stent“chimney”technology can provide treatment opportunity for the patients suffering from left common carotid artery rupture accompanied by aortic dissection; the rupture can be completely obstructed and the blood flow can be reconstructed. The short-term effect is satisfactory, although the long-term effect needs to be further studied.
