OBJECTIVE:To establish the quality standard for Chaige ganmao mixture. METHODS:TLC was conducted to iden-tify the Scutellaria baicalensis and Paeonia lactiflora;HPLC was conducted to determine the content of puerarin. The column was Zorbax Eclipse XDB-C18 with mobile phase of methanol-water(25:75,V/V)at flow rate of 1.0 ml/min,detection wavelength was 250 nm,and column temperature was 25℃,and the injection volume was 5μl. RESULTS:TLC showed clear spots and good sepa-ration. The linear range of puerarin was 18-198 μg/ml(r=0.999 9);RSDs of precision,stability and reproducibility tests were low-er than 2%,recovery was 99.04%-99.75%(RSD=0.28%,n=6). CONCLUSIONS:The standard can be used for the quality con-trol of Chaige ganmao mixture.

Patients with metastatic prostate cancer are typically managed with androgen deprivation therapy. Most patients initially respond to treatment, but many eventually develop castration-resistant prostate cancer. Neuroendocrine prostate cancer (NEPC) is a highly aggressive subtype of castration-resistant prostate cancer, which often results from neuroendocrine differentiation of prostate cancer cells. NEPC has a dismal outcome with an average survival of less than 1 year and exhibits less response to radiochemotherapy. At least 25%of patients with lethal castration-resistant prostate cancer are predicted to eventually develop this type of highly-aggres-sive NEPC. However, research on the molecular mechanism of NEPC is limited;thus, further studies are needed to explore the develop-ment and application of anticancer drugs for NEPC.

Objective To investigate the expression and clinical significance of UL16 binding protein 3 (ULBP3) in human esophageal squamous cell carcinoma (ESCC) and its correlation with nature killer (NK) cells.Methods The relative expression of ULBP3 in the ESCC tissues and corresponding carcinoma adjacent tissues of 40 patients was detected by realtime-poly merase chain reaction (PCR),immunohistochemical staining and Western blot methods.The percentage of NK cells in peripheral blood of same patients was examined by flow cytometry.The correlation between ULBP3 and the percentage of NK cells was analyzed with Pearson method.Results The expression of ULBP3 at mRNA level in the tumor tissues ([4.96 ±-6.11]×10-3) was significantly higher than that of corresponding carcinoma adjacent tissues ([1.64 ± 2.96]× 10-3,t =3.656,P＜ 0.01).The immunohistochemical staining results indicated that the positive rate of ULBP3 in the tumor tissues was 60％ (24/40),however that of corresponding carcinoma adjacent tissues was only 32.5％(13/40,t=3.921,P＜0.01).The Western blot results indicated that the expression of ULBP3 at protein level in the tumor tissues was significantly higher than that in the corresponding carcinoma adjacent tissues.The relative expresssion ULBP3 at mRNA level in carcinoma tissues of ESCC patients with lymph node metastasis and at TNM stage Ⅲ was higher than that of ESCC patients without metastasis and at TNM stage Ⅰand Ⅱ (t=4.839,4.192,P＜0.05).There was no significant correlation between the expression and ages,gender,location of tumors and the differentiation degree of tumor (P＞0.05).At early and mid stage of the tumor,the expression of ULBP3 at mRNA level was positively correlated with the percentage of NK cells in peripheral blood (r=0.5233,P＜0.05),however there was no correlation at advanced stage.Conclusion ULBP3 was highly expressed in ESCC and may be involved in the immune regulation of NK cells.

Objective To investigate the correlation between vertebral artery dominance (VAD) and posterior circulation ischemic stroke (PCIS).Methods The consecutive patients with acute ischemic stroke hospitalized from November 2013 to October 2015 were collected.All patients underwent MRI and magnetic resonance angiography (MRA).The dominant vertebral artery was defined as having the larger diameter if left and right diameter difference ≥0.3 mm or the vertebral artery connected to the basilar artery in a more straight fashion if the diameter difference ＜ 0.3 mm.They were divided into either an anterior circulation ischemia stroke (ACIS) group or a PCIS group according to the classification criteria of Oxfordshire Community Stroke Project (OCSP).A multivariate logistic regression analysis was performed to investigate the correlation between VAD and PCIS.Results A total of 226 patients withacute ischemic stroke were enrolled,including 172 patients (76.1％) in the ACIS group and 54 (23.9％) in the PCIS group.Fifty-four patients (23.9％) had VAD,including 38 (70.3％) on the left and 16 (29.7％) on the right.The proportion of the patients with VAD in the PCIS group was significantly higher than that in the ACIS group (55.6％ vs.14.0％;x2 =39.115,P ＜ 0.001).Multivariate logistic regression analysis showed that VAD was an independent risk factor for patients occurring PCIS (odds ratio,13.60,95％ confidence interval 6.90-27.01;P＜0.001).Conclusions VAD is closely associated with the occurrence of PCIS,and it is an independent risk factor for PCIS.

Objective To measure and analyze the staffing standards of family doctor interdisciplinary team by means of the WHO workload indicator of staffing need (WISN)method,for reference of the government in building family doctor interdisciplinary teams.Methods 150 community health centers in 16 provinces were selected.The related data from 150 centers were collected to analyze the population served by each family doctor,and the staffing standards of family doctor interdisciplinary team by means of the WHO workload indicator of staffing need(WISN)method.Results There were 10 721 community health professionals in the sample centers which provide 132.14 million standard equivalents of service to the public.1 9 6 1 6 community health professionals were needed to ensure the quality of service and no extra workload after work for professionals.Averagely,each family doctor can serve 1 558 residents,who needs 1.3~1.5 nurses or public health workers.Conclusions A huge gap was found for community health professionals.The population served by each family doctor should be lowered compared to the governmental requirement and more nurses should be introduced to the family doctor interdisciplinary team.
