Objective To investigate whether or not the pulmonary artery participates in the blood supply of lung cancer and its change of morphology and blood flow in lung cancer. Methods Two different colors of silicone were injected separately into the bronchial and pulmonary arteries of 33 rat models with squamous cell carcinoma of lung. The origin of blood supply of lung cancer and the morphologic change of pulmonary artery were observed under a stereomicroscope. The DSA of bronchial and pulmonary artery were performed simultaneously in 28 patients with lung cancer. Results The pulmonary branch of rat and patients were reduced, thinned and occluded in the affected lung. The pulmonary artery did not form tumor vessel, and pulmonary blood flow and perfusion were reduced or absent in the affected area. Conclusion The pulmonary artery didn′t participate in the blood supply of lung cancer. It is unreasonable to perform transcatheter chemo embolization for lung cancer via pulmonary arteriay.

AIM: To explore the variation of blood biochemistry and arterial blood gas of patients with systemic inflammatory response syndrome (SIRS) in the early time after trauma and improve the diagnosis and first aid. METHODS: Eighty-eight patients with trauma from August 2003 to February 2004 were divided into two groups by their AIS-ISS90 score. The data of temperature, pulse, respiratory rate, white blood cell counts, Hb, blood glucose and arterial blood gas (PaO 2, PaCO 2, HCO 3 -, AG) were collected and compared with each group by statistic methods. RESULTS: Of the 88 patients, 49 underwent SIRS, 12 in light trauma group (ISS≥16) and 37 in severe trauma group (ISS45 mmHg or 0 05). 13 patients had MODS in severe trauma group and 2 died while none had MODS or died in light trauma group. CONCLUSION: Application of AIS-ISS90 and SIRS-related blood biochemistry and arterial blood gas is beneficial for the diagnosis and treatment for patients in the early time after trauma. [

Objective To study the effect of Chinese Herb of Yigan Granules in different dosages on bile secretion in rats.Methods The rats were randomly divided into 5 groups: blank control group,positive control group and high,mod erate,low dosages of Yigan Granules groups.The medicines were administered thr ough duodenal intubation for the rats.Then the volume of bile were gathered by common bile duct intubations in different time,and the volume of bile and the contents of bilirubin in bile were tested before and after given drugs.Results Yigan Granules increased the bile secretion in a dose-dependent manner and promote the secretion of bilirubin.Conclusion Chinese Herb of Yigan granules has a choleretic effect.

Objective: To analyze the phytosterols content in cereals and legumes commonly consumed in China, and to estimate the intake of phytosterols in Chinese people. Methods: 25 cereals and 16 legumes were chosen as samples. The content of ?-sitosterol, campesterol, stigmasterol, ?-sitostanol, campestanol were analyzed by GC methods and the total phytosterols were calculated; The intake of phytosterols in Chinese people were estimated using the data of “Survey on the Status of Nutrition and Health of the Chinese People” in 2002. Results: The content of phytosterols in wheat flour was higher than that in rice. The refinements of cereals will decrease the phytosterols content. Phytosterols content in soybean was higher than other legumes. The intake of phytosterols in Chinese people was estimated to be 130.76mg/d from cereals and 7.86mg/d from legumes. Conclusion: The analysis of phytosterols in food and the estimation of daily intake is valuable for chronic disease prevention. The higher consumption of wheat flour and legumes in diet is recommended.

Xanthone and its derivatives occupy a large part of the family of natural polyphenolic compounds with various biological and pharmacological activities.In recent years (from 2006 to 2011),it was reported that 127 xanthones were discovered from plants and fungi using various modem separation methods including silica gel/polyamide column chromatography,HPLC,high-speed counter-current chromatography,high-performance centrifugal partition chromatography,etc.Since total synthesis and structure modification for xanthone and its derivatives have been given attention worldwide,we introduced the synthetic methods of xanthone skeletons as well.Unfortunately,to date,there are still weaknesses in current methods of separation and synthesis,which need to be improved.This review,to a certain extent,provides necessary foundation for the further research and development of medicines containing xanthone and its derivatives.

Objective To investigate the changes of cardiac structure and function in patients with hepatolenticular degeneration (HLD).Methods From March 2010 to February 2011,90 HLD patients who did not receive formal treatment (observation group) and 30 healthy people (control group) were collected and analyzed with color Doppler echocardiography in the Institute of Neurology,Affiliated Hospital of Anhui University of Traditional Chinese Medicine.Based on the clinical manifestations,cases were divided into hepatic type group (n =31),brain type group (n =42) and brain-visceral type group (n =17).According to the Child-Pugh classification,patients were divided into Child A group (n =71),Child B group (n =10) and Child C group (n =9).Results (1) The left atrial diameter ((28.00 ± 3.11),(29.62 ± 3.44) mm) and left ventricular diameter ((45.69 ± 3.75),(47.10-± 4.73) mm) of HLD patients in brain-visceral type group and hepatic type group were larger than that of the control group ((24.86 ± 2.63),(41.93 ±3.56) mm;t =3.143,4.761,P=0.018,0.000;t=3.764,5.167,P=0.018,0.000).The left atrial diameter and left ventricular diameter of hepatic type group were significantly larger than the brain type group (26.06 ± 3.68,43.34 ± 3.88;t =3.557,P =0.000;t =3.751,P =0.001).The value of E/A in the hepatic type group (1.57 ± 0.37) was significantly lower than the control group (1.93 ± 0.20;t =-0.352,P =0.006).(2) The left atrial diameter ((31.29 ± 1.70),(34.67 ± 1.97) mm) and left ventricular diameter ((48.29 ± 2.81),(53.67 ± 2.67) mm) of Child B and C groups were significantly larger than the control group ((24.86 ± 2.63),(41.93 ± 3.56) rm;t =6.429,9.810,P =0.000,0.000;t =6.357,10.738,P =0.000,0.000),and the Child A group ((26.42 ± 3.05),(43.89 ± 3.76) rm;t=4.871,8.252,P=0.000,0.000;t =4.399,8.780,P=0.003,0.000).The value of E/A of Child B and C groups (1.58 ± 0.32,1.26 ± 0.39) was lower than that of the control group (t =-0.347,0.662,P=0.020,0.000);At the same time,the value of E/A of Child C group was significantly lower than that of Child A group (1.80 ± 0.33;t =-0.530,P =0.000).Conclusions The HLD patients may have cardiac structural and functional changes,mainly manifested as left atrial and left ventricular enlargement and cardiac diastolic dysfunction,whereas a serious impact has not yet been found in systolic function.And the changes of cardiac structure and function were related to the degree of liver cirrhosis in patients with HLD.

Background and purpose:Protein kinase C (PKC) is a potentially important target for cancer therapy due to its potential role in carcinogenesis. Abnormal expression and increasing activity of PKC-?are present in non-small cell lung cancer (NSCLC).The aim of this study is to investigate PKC-? protein expressions in lung cancer tissues by tissue microarray and their significance. Methods:Using tissue microarray, PKC-? protein expression in lung cancer patients was examined by immunohistochemistry. 182 samples of umor tissues and 18 samples of adjacent tissues were taken;of the 182 samples, 160 were NSCLC tissues and 22 were SCLC;102 samples from stage I cases and 58 from stageⅡ-Ⅲ cases.Results:Expression of PKC-? protein was observed in 48.3% (88/182) of cancerous tissues and 16.7% (3/18) of adjacent tissues (P
