Objective To understand the influencing factors of the post competency of health technical personnel in township hospitals in a prov-ince,so as to provide scientific reference for improving health professionals'post competency. Methods Using stratified cluster random sam-pling,1242 health professionals from township health centers and village clinics of 14 cities were extracted and then surveyed with questionnaire. Results The average score of the respondents'post competency was 3.43,which meant they could afford most of the work. Multiple linear re-gression analysis showed that the main influencing factors of the professionals'post competency included gender,age,specialty,and training. The female,senior,nursing and health-care professionals with training exhibited a better post competency. Conclusion To realize the further develop-ment of professionals'post competency,medical students should not only be early clinical and more clinical,but also actively participate in the training and continue the education after entering the clinic. On the other hand ,the government should define the function orientation of the town-ship healthy centers and explore human resource management mode based on the post competency.

Objective To compare the consistency between interstitial fluid glucose and arterial blood glucose in septic shock patients with different tissue perfusion levels.Methods A prospective investigative study was conducted. Sixty-one septic shock patients with ages above 18 years old admitted to the Department of Critical Care Medicine of Peking Union Medical College Hospital, Chinese Academy of Medical Sciences from April 2013 to December 2013 were enrolled. The real-time continuous glucose monitoring system (RTCGMS) and arterial blood gas analyzer were used to measure the patients' interstitial fluid glucose and arterial blood glucose, and according to the criteria of International Organization for Standardization (ISO) and the median of relative absolute difference (Median RAD), the consistency between interstitial fluid glucose and arterial blood glucose was calculated. Based on the lactate (Lac) level and pulse oxygen perfusion index (PI), the septic shock patients were divided into groups with different degrees of tissue perfusion, the consistency between the interstitial fluid glucose and arterial blood glucose among septic shock patients with different degrees of tissue perfusion was compared by using Bootstrap re-sampling technique.Results Negative correlation existed between PI and Lac (r= -0.272,P < 0.001), which showed the opposite change tendency of organism tissue perfusion. In patients with Lac > 8 mmol/L, their consistency between interstitial fluid glucose and arterial blood glucose was better than that in those with Lac > 2-4 mmol/L, and the 95% credibility intervals (CI) of ISO standardized deviation value was 0.026-38.710 (P < 0.05). In patients with PI ≤ 0.7%, their consistency between interstitial fluid glucose and arterial blood glucose was better than that in those with PI > 0.7%-1.4%, the 95%CI of median RAD difference value was 0.002-0.076, and the 95%CI of ISO standardized deviation value was -27.000 to -0.583 (allP < 0.05); in patients with PI > 3.0%, their consistency between interstitial fluid glucose and arterial glucose was better than that in those with PI ≤ 0.7%, PI > 0.7%-1.4% and PI > 1.4%-3.0%, and the 95%CI of ISO standardized deviation values were 3.322-28.302, 11.988-40.265 and 5.170-33.333 respectively (allP < 0.05).Conclusions When septic shock patients were under low tissue perfusion (Lac > 8 mmol/L or PI ≤ 0.7%), the worse the tissue perfusion, the better the consistency between interstitial fluid glucose and arterial blood glucose; when septic shock patients were under normal local tissue perfusion (PI > 3.0%), the better the local tissue perfusion, the better the consistency between interstitial fluid glucose and arterial blood glucose.

Objective To analyze the clinicopathologic characteristics of atypical polypoid adenomyoma (APA) of endometrium,and investigate the special characteristics of cancerous transformation from APA.Methods Fourteen cases of APA were collected in General Hospital of People' s Liberation Army from January 2007 to March 2013.The clinical data,morphologic features,immunohistochemistry and the related literature were reviewed.Results The median age of the 14 patients was 38 years (ranged from 23 to 72 years),only 1 patient was postmenopausal.The most common symptom was irregular vaginal bleeding (4/14),and 4 patients were identified during routine physical examination for infertility.Among 14 cases,4 cases were diagnosed as well differentiated endometrioid adenocarcinoma originating from APA,and their median age was 35 years (ranged from 28 to 41 years); color Doppler flow imaging (CDFI) of ultrasound showed rich blood flow signal.The tumors with cancerous components were obviously larger than the usual APA (mean diameter:4.7 versus 1.8 cm).Histologically,irregular and branched glands were embedded in fibromuscular stroma and the glandular epithelium were atypical hyperplasia in varying degrees.While carcinoma developed in the APA,the sieve,solid and papillary structures were noticeable,and necrosis were common.Conclusions APA is a rare lesion of the uterus.Although the clinical behavior is benign in most cases,there may be possible for some cases developing carcinomas.If the APA mass is more than 4 cm in diameter,and microscopically demonstrates prominent sieve,solid,papillary structures and necrosis,the diagnosis of carcinoma developed from APA can be made.Thorough analysis should be done before the most proper therapeutic regimen is drawn up.

At present, studies on traditional Chinese medicine (TCM) properties are mostly restricted to a single or two kinds of medicinal properties, but deviated from the holism of the theoretical system of TCMs. In this paper, the characteristics of pharmacological effects of different property combinations of TCMs distributing in the stomach meridian were take as the study objective. The data of properties of TCMs distributing in the stomach meridian was collected from the Pharmacopoeia of the People's Republic of China (2005). The data of pharmacological effects of TCMs distributing in the stomach meridian was collected from all of literatures recorded in Chinese Journal Full-text Database (CNKI) since 1980, Science of Chinese Materia Medica (Yan Zhenghua, People's Medical Publishing House, 2006) and Clinical Science of Chinese Materia Medica (Gao Xuemin, Zhong Gansheng, Hebei Science and Technology Publishing House, 2005). The corresponding pharmacological effects of property combinations of TCMs distributing in the stomach meridian was mined by the method of association rules. The results of the association rules were consistent with the empirical knowledge, and showed that different medicinal property combinations had respective pharmacological characteristics, including differences and similarities in pharmacological effects of different medicinal property combinations. Medicinal property combinations with identical four properties or five tastes showed similar pharmacological effects; whereas medicinal property combinations with different four properties or five tastes showed differentiated pharmacological effects. However, medicinal property combinations with different four properties or five tastes could also show similar pharmacological effects. In this study, the medicinal property theory and the pharmacological effects of TCMs were combined to reveal the main characteristics and regularity of pharmacological effects of TCMs distributing in the stomach meridian and provide a new way of thinking and method for revealing the mechanism action of TCMs distributing in the stomach meridian and discovering the pharmacological effects of TCMs distributing in the stomach meridian.

Objective Neuroinflammation following traumatic brain injury (TBI) may give rise to neurodisorder.This study aimed to investigate the effect of intranasal delivery of nerve growth factor ( NGF) on neuroinflammation following TBI and its action mechanism in rats. Methods Thirty-six male adult Sprague-Dawley rats were equally divided into a sham , a TBI, and a TBI+NGF group.The rats in the TBI +NGF group were treated with NGF intranasally at 12 and 24 hours after TBI.The levels of IL-1βand TNF-αin the injured cerebral cortex were detected by ELISA , the DNA-binding activity of NF-κB evaluated by EMSA , and the expres-sion of amyloid-β( Aβ42 ) determined by Western blot . Results NGF attenuated the inflammation following TBI .Compared with the TBI group, the level of IL-1βwas obviously decreased in the TBI +NGF group at 12 hours (70.65 ±3.10 vs 37.51 ±1.92) and 24 hours (68.85 ±8.10 vs 36.23 ±2.99, P<0.05), and so was that of TNF-α(47.12 ±7.38 vs 27.63 ±5.77 and 56.15 ±11.20 vs 29.94 ±8.62, P<0.05).The DNA-binding activity of NF-κB was reduced to 111.62 ±0.49 and 131.52 ±0.88, and the expression of Aβ42 to 0.23 ±0.008 and 0.52 ±0.004 at 12 and 24 hours respectively after treatment with NGF , both with statistically significant differences from the TBI group (P<0.05). Conclusion Intranasal administration of NGF attenuates TBI-induced neuroinflamma-tion in rats, which may be associated with its regulatory effect on the Aβ42/NF-κB signaling pathway .
