Objective To investigate the vasodilatation effects of total flavonoid from polygonum aviculare on rat thoracic aorta and its underlying mechanisms. Methods Total flavonoid from polygonum aviculare was gotten by extracted with 65% alcohol, gathered with polyamide, and eluted with 75% alcohol.The content of flavone was determined with rutoside as standard preparation. Normal rats thoracic aorta in vitro used as sample, BL-420E biological functional experiment system was utilized to record dilatation effect of total flavonoid on PE affecting pre-contracting blood vessel and the relation between dilatation effect of total flavonoid on blood vessel and calcium influx. Results Total flavonoids from polygonum aviculare can diastole contractions of thoracic aorta caused by PE. In calcium-free perfusion, gradually adding CaCl2 induced calcium influx. Clinical data showed dose-effect relation between drug and blood vessel contraction decreased in the total flavonoids from polygonum aviculare incubation rats than normal rats. Besides, total flavonoids from polygonum aviculare can obviously inhibit contraction of blood vascular circle induced by calcium releasing.Conclusion FP exerted a dose-dependent vasodilatation effect on rat isolated aorta rings by inhibiting Ca2+influx via L-type voltage-gated Ca2+ channels and Ca2+ release from sarcoplasmic reticulum, consequently decrease Ca2+ in vascular smooth muscle cells.

4. Surgical procedure and prognotic analysis of extrahepatic cholangiocarcinoma: A report of 161 cases
Tumor 2008;28(3):251-255
Objective: To explore the impact of clinical features and surgical procedure on survival of extrahepatic cholangiocarcinoma (EHCC) and the prognostic factors in patients with EHCC after curative resection. Methods: From 1995 to 2006, 161 EHCC patients undergoing operations were included in this study. The clinical features, diagnosis, surgical procedure and follow-up data were retrospectively analyzed. Factors influencing postoperative survival were analyzed using COX multiple stepwise regression model. Results: Of the 161 patients, 110 underwent radical resection and 32 underwent palliative resection, 19 underwent drainage or laparotomy. The overall 1-, 2-, 3-,and 5-year survival rates were 74.9%, 45.3%, 36.5%, and 11.1%, respectively. COX analysis showed hepatic infiltration, portal vein and/or hepatic artery invasion, and lymph node metastasis were independent prognostic factors after radical resection (P < 0.05). Conclusion: The radical resection is the key factor for increasing the long-term survival rate and improving the life qualities of EHCC patients. Partial hepatectomy or/and pancreatoduodenectomy in combination with skeletonization may be helpful for increasing radical resection rate and long-term efficacy.

Objective To discuss the diagnosis and treatment of renal tuberculosis.Methods A retrospective study was made on 96 cases.Results Frequency (51.8%), urgency (37.2%),odynuria (33.4%),lumbodynia (41.0%),and hematuria(48.1%)were the most common symptoms. The diagnostic accuracy of IVU, B-type ultrasonography, CT and biopsy of mucous membrane of urinary bladder were 69.1%,12.5 %,37.5% and 33.3% respectively. 96 cases were given medicine (INH+RFP+PZA or PIA for 6-8 months).38 cases(39.6%)have been cured, while symptoms of 43 cases (44.8%) have been improved. Operation was performed on 15 cases that were ineffective treated by chemical therapy. Conclusions Urine routine, IVP, cystoscopy+biopsy of mucous membrane of urinary bladder provide important information for the diagnosis of renal tuberculosis. INH, REP and EMB or PIA combination therapy yields satisfactory outcome for early cases.

OBJECTIVE:To screen the optimal technology of dog testes and penis processed with talcum powder,and to pro-vide reference for the formulation of quality control standard. METHODS:Taking the comprehensive score of crushing rate and the content of alcohol soluble extract as evaluation indexes,L9(34) orthogonal test was used to optimize processing temperature,pro-cessing time and the amount of talcum powder;validation test was conducted. According to related method in Chinese Pharmaco-poeia(2015 edition),the contents of moisture,ash,nitrogen and alcohol soluble extract were determined,and automatic amino ac-id analyzer was used to determine the content of amino acids in samples. RESULTS:The optimal processing technology were that 100 kg dog testes and penis should add into 40 kg talcum powder;the processing temperature was 350-380 ℃;processing lasted for 4 min. Results of verification test showed that the average crushing rate and the content of alcohol soluble extract were 80.2%(RSD=0.95%,n=3)and 15.7%(RSD=2.30%,n=3). In processed dog testes and penis,the contents of moisture,ash,nitro-gen and alcohol soluble extract were 5.7%,18.7%,8.3%,15.7%,respectively. Besides,there still were 16 kinds of amino ac-ids,and their total content was 42.44%. CONCLUSIONS:The optimized talcum powder processing technology of dog testes and penis is stable and practical. The content of moisture,ash,nitrogen,alcohol soluble extract and amino acid can be used as impor-tant quality standard control indexes for processed dog testes and penis.

Objective To test intraoperative radiotherapy with mobile photon beam using the INTRABEAM system ( Germany) , and to analyze the dosimetric characteristics of low?energy photon beam using X?ray source and spherical applicators and explore its potential limitations in clinical application. Methods A special water phantom, a parallel?plate ionization chamber, and an electrometer were used to measure the depth dose rates and isotropy of dose distribution in x/y plane of X?ray source and different spherical applicators in the INTRABEAM system. Those data were then compared with the system data. Results For the X?ray source, the deviation of observed depth dose rate and isotropy in the x/y plane from the system data were-2.16%± 1. 36% and-1.9%~ 2. 1%, respectively. For applicators with different diameters, the deviation of observed depth dose rate, transfer coefficient, and isotropy in x/y plane from the system data were-10.0%~2. 3%,-8.9%~4. 2%, and-1.6%~2. 6%, respectively. Surface dose rate and dose gradient became larger with the decrease in the diameter of the spherical applicator. The measurement of depth dose rate and isotropy of X?ray source and spherical applicators showed good repeatability. The influencing factors for measurement accuracy included the positioning error of ionization chamber, energy response, noise current, and correction factor f ’ ( R ) . Conclusions This study reveals the dosimetric characteristics of the INTRABEAM system, verifies the accuracy of the system data, and obtains the data for clinical application and routine quality assurance. However, large dose gradient and small therapeutic range may limit its wide clinical application.
