Analysis of the nature, tastes, channel distributions and effects of the frequently used herbal medicines in the prescriptions involved in the clinical literatures about treatment of gastric cancer published from 1988 to 2007 was made in the paper. The literatures were categorized into three types: 1) treatment of middle- and late-stage gastric cancer; 2) prevention and treatment of the recurrence and metastasis after operation; 3) Chinese herbal medicines combined with chemotherapy for enhancing efficacy and reducing toxicity. The most frequently used herbal medicines in the three literature types were qi-invigorating herbs, such as Atractylodes, Astragalus, Codonopsis, Glycyrrhiza and Ginseng, etc. The herbal medicines for promoting urination to subside swelling such as tuckahoe and Semen Coicis, etc were used more frequently than the herbal medicines for regulating qi such as dried orange peel and putchuck, etc, as well as for clearing away heat to remove toxin such as spreading hedyotis herb, Herba Scutellariae Barbatae, yangtao actinidia root, and Rhizoma Paridis, etc. From another angle, the most frequently used herbal medicines for the treatment of gatric cancer were those cold, warm and neutral in nature, sweet, bitter and pungent in taste, and distributed to spleen and liver channels.

To determine whether p53 gene transcripts were altered in thyroid tumor and adjacent tissues of thyroid tumor, total RNA from 12 tumor specimens (9 carcinomas and 3 adenomas) and 4 adjacent tissues of thyroid tumor was exmined by Northern blot hybridization and reverse transcription——polymerase chain reaction. It was found that p53 gene transcripts were present in all tumors and the adjacent tissues of tumor and were significantly more obvious in the samples of carcinomas as compared with those of adenomas and in the samples of tumor as compared with those of the adjacent tissues of tumor. These data suggest that excessive p53 gene expressions are involved in thyroid carcinogenesis.

Objectives:To understand the patients' cognition and satisfaction with public welfare in public hospitals.Methods:A questionnaire survey was conducted among 600 patients in Beijing municipal public hospitals and the data was statistically analyzed by SPSS 22.0.Results:Patients' understanding of public welfare was not ideal,the satisfaction was quite well,and the satisfaction of the patients in the experimental hospitals was more satisfactory than those in non-experimental hospitals.The patients have urgent needs on rational drug use,mutual recognition of medical results,smooth channels of patient rights,reduced medical expense and shortened waiting time.Conclusions:It should strengthen the publicity and governance of the public welfare of public hospitals to enhance the patients' understanding,breakthrough the urgent needs of public welfare to improve patients' satisfaction,and intensify the policy linkage and explore diversified implement forms of public welfare to improve service level.

Objective To investigate the effect of old myocardial infarction on the heart rate variability.Methods Totally 86 patients with old myocardial infarction and 78 healthy people were enrolled in the study.Twenty-four-hour heart rate variability in the time domains including NN,SDNN,SDANN,RMSSD,and PNN50 and the frequency domains including VLF,LF,HF,and LF/HF were analyzed.Results Both the time domain and frequency domain indexes of the heart rate variability in patients with old myocardial infarction significantly decreased than those in the healthy peolple（P 0.05）.Conclusion There might be autonomic nervous system dysfunction in the patients with old myocardial infarction.

Cyclic peptide drugs have gradually become an emerging research direction due to their some favorable properties such as high-efficiency binding affinity, high selectivity, lower toxicity, and stable metabolism. In recent years, the number of cyclic peptide drugs under clinical research has continued to increase. Unlike the previous cyclic peptide drugs, which were mostly derived from natural products and their derivatives, these cyclic peptide drugs are designed by genetically encoded display technologies which are based on rational design and in vitro evolution (such as BT1718, PTG-300, POL6326, etc). Among them, phage display technology has some advantages such as mature research system, low cost, and simpler operation that make it well recognized and praised by the majority of researchers in this field. Here, we reviewed the recent progress of applying phage display technology to explore diverse cyclic peptide libraries, which, we believe, will contribute more valuable candidate cyclic peptide drugs in clinical research.

Objective To investigate the correlation between patient' s age and expression of Ki-67 or microvessel density in primary hepatocellular carcinoma.Methods The expression level of Ki-67 and the microvessel density in the hepatocellular carcinoma tissues were detected by immunohistochemical method,and the correlation between age and expression of Ki-67 or microvessel density were analyzed.Results In 48 cases of hepatocellular carcinoma tissues,Ki-67 expressed to varying degrees,but the positive rate was 83.3 ％ (40/45),and there was no expression in corresponding noncancerous tissues (P ＜ 0.01).Microvessel density marked by CD34 in cancer tissues and noncancerous tissues were 32.17±8.06 and 10.83±2.85 respectively.Microvessel density of cancer tissues was higher than noncancerous tissues (P ＜ 0.01).Both levels of Ki-67 expression and microvessel density in hepatocellular carcinoma were negatively correlated with the age (r =-0.418,P =0.003 and r =-0.443,P =0.002 respectively).Conclusion Both levels of Ki-67 expression and microvessel density in hepatocellular carcinoma are negatively correlated with patient' s age,which may suggest worse prognosis for the younger patients.

Endoplasmic reticulum stress(ERS) is a kind of subcellular pathological state,and associated with many diseases.Recently,the research of ERS on chondrocyte is at the beginning stage,and may be involved in pathogenisis of rheumatoid arthritis(RA) and osteoarthritis(OA).It has been proved that ERS can interfere the differentiation of chondrocyte,decrease the synthesis of abnormal protein,attenuate the injury of cell.But overreaction of ERS can cause chondrocyte apoptosis through an independent pathway without of Fas and NO.There are three signal transmission passages in ERS:ATF-6(activating transcription factor 6)、Ire 1(inositol-requiring 1)and PERK(PKR-like ER kinase).The three protein molecules activate apoptotic genes by TRAF-2(TNF receptor-associated factor 2)and GADD153(growth arrest and DNA-damage-inducible gene 153),initiate the chondrocyte apoptosis.Therefore,ERS may effect the pathogensis of RA and OA by modulating chondrocyte function and inducing apoptosis,but more research are needed to reveal the mechanism.

Disseminated malignancy is the main cause of cancer-related death.The spontaneous circulation of tumor cells is responsible for distant metastasis;therefore it is of potential importance to specifically and sensitively detect the circulating tumor cells,which not only allows for more accurate prediction of cancer prognosis,but also helps to tailor individualized anticancer treatment.This paper reviews the enrichment,detection and analyzing methods of circulating tumor cells.
