Objective To explore the clinical significance of the inferior displacement sign on the initial anterioposterior (AP) view X-ray for fractures of humeral greater tuberosity.Methods This study retrospectively analyzed the imaging and clinical data of 24 patients with isolated fracture of humeral greater tuberosity who had sought medical treatment during the period from January 2008 to June 2015.They were 10 males and 14 females,with an average age of 54 years (from 19 to 68 years).Laterality:8 left sides and 16 right sides.The AP view X-ray films of the 24 patients present the inferior displacement sign defined as the inferior cortical margin of the greater tuberosity overlapping the proximal humeral shaft on the initial AP view.The patients received further CT examination to determine the displacement direction and whether the humeral neck fracture was complicated.Results A slight displacement of humeral anatomic neck fracture was shown on the initial AP view X-ray in 10 patients.Further CT examination revealed that humeral anatomic neck fracture was confirmed in 23 patients,the greater tuberosity was displaced posteriorly in 22 patients and posteroinferiorly in 2 patients.Radiographic measurements showed:the mean posterior displacement was 10.5 ±4.5 mm;the displacement between the humeral head and the humeral shaft was 2.5 ± 1.5 mm;the neck shaft angle was 147.2° ± 9.2°;the distance between the humeral head and greater tuberosity was 10.8 ± 3.4 mm;the overlap between the inferior edge of greater tuberosity and the upper edge of lateral humeral shaft was 12.5±5.9 mm.Pearson correlation analysis showed no correlation between the overlap and the head-tuberosity distance (P ＞ 0.05),but a significant correlation between the overlap and the neck-shaft angle (P ＜ 0.05).Conclusions The inferior displacement sign on the initial AP view X-ray is actually the overlap of posterior displaced greater tuberosity fracture shown on the X-ray.The posterior displaced greater tuberosity fracture complicated with slight displaced anatomic neck fracture is a presentation of the valgus impacted fracture of the proximal humerus.The inferior displacement sign in the fracture of humeral greater tuberosity can highly suggest the presence of occult or slight displacement of the humeral anatomic neck fracture.

[Objective] Preliminary clinical experience of Wang Zuoshun using Da Chaihu decoction contacts with other decoctions in the treatment of re-fractory hypertension in winter. [Methods] From the etiology and pathogenesis, syndrome differentiation and treatment, clinical treatment experience sum-mary of Professor Wang Zuoshun 's treatment of winter refractory hypertension academic ideas and clinical experience, also from the classical articles, the-ory of constitution etc to expound the omechanisationf the clinical experience.[Results] The etiology is phlegm, blood stasis, induced by cold pathogen, its pathogenesis are dysfunction of Shaoyang, accumulation of phlegm-heat and blood stasis, cold accumulation, according to the etiology and pathogenesis, forming a cardinal in Shaoyang, purging heat, resolving phlegm and removing blood stasis, slightly with temperature and the treatment. [Conclusions] In clinical work, Wang Zuoshun director using syndrome differentiation and treatment, researches the pathogenesis, flexibility in the use of traditional Chinese herbal soup recipe in treating winter refractory hypertension, the curative effect is remarkable, and has popularization and application value.

Objective: In this study,we evaluatedthe influence of different nutritional support routes and nutrients on the intestinal barrier function and bacterial translocation in rats with gut I/Rinjury. Methods: Eighty rats were divided randomly into: I/R group,control group,and nutrition-supportgroups. Bacterial culture, D-lactate and endotoxin levels was assayedafter 7 days of nutrition support. Results: There was serious damagein intestinal tissue of I/R group. Remarkably higher value of bacterial translocation occurred in PN group (P0.05).The endotoxin level was the highest in PN group. Conclusions: TPN alone could impair gut immune barrier function and thereforefacilitate bacterial translocation.The use of immunonutritionindicates limited efficacyin preventing bacterial translocation compared with common enteral nutrition.

The contents of tea polyphenolic compounds, ascorbic acid, flavones and tea catechins in 17 kinds of Chinese tea were reported.In multivariable analysis, both factor analysis and regression technique were used to assess the realationship between blocking rate (transferred into In odd, dependent variable) and tea active constituents (independent variable) . It has been shown that the correlation coefficient between each pair of independent variables is comparatively high. One main factor could explain 80% of variation among independent variables, of which the factor loadings were 0.951 (tea catechins), 0.88 (tea polyphenolic compounds), 0.842 (ascorbic acid). It has been found that tea polyphenolic compounds had a higher contribution to the blocking rate. The blocking rates on NPRO formation were 88% for 2 ml green tea extract, 74% for tea polyphenolic compounds extracted from 2 ml green tea, and 75% for 20 mg of tea catechins, the same amount as contained in 2ml of tea extract. The blocking rate -was 28% for the same amount of ascorbic acid contained in 2 ml of tea extract, and therefore ascorbic acid in tea didn't play an important role in the blocking of NPRO formation. Tea polyphenolic compounds and tea catechin affected NPRO formation in the same manner as tea extract, i.e. inhibtion in higher level and promotion in lower level. Thus, it might be concluded that blocking effect on NPRO formation was mainly due to tea polyphenolic compounds especially tea catechin in tea.

In this article, the manifestations of the DSA in 100 patients with primary hepatic carcinoma have been studied. According to the haculta the authors put forward a method for classification by DSA findingas of the hapatic carcinoma, It can be expressed in A B C D. A represents the site and shape of the tumor; B represents the blood supply; C represents having or not having arterial - venous fistula; D represents the condition of the portal vein. Simnltaneouly the authors pointed out its clinical significance by reflecting the whole changes of the fumor in morpholygy and hemodynanics useful to plan an interventioanl therapy, and to assess the prognosis.

Objective To investigate the effects of taxol on QBC939 and its mechanism. Methods The cell proliferation was assessed by MTT assays; cell cycle kinetics and apoptosis were analyzed by flow cytometry and microscopic examination. Results Taxol inhibited the cell growth in concentration and time-dependent manners. The cell showed S and G2/M arrest and apoptosis. Conclusion Taxol suppresses the growth of QBC939 cells in vitro by causing cell-cycle arrest, and apoptosis of the cells.The mechanisms of taxol will provide theoretical guidance for clinical treatment.

This paper analyzes the document contents of targeted admission medical students in 16 provinces of China in 2016.Through analyses of the characteristics of the program, this study found that, 1) the number of admissions is determined by the national level and issued to the provincial level, where rural students are the main source of students, undergraduate program is the main enrollment category, and clinical medicine and traditional Chinese medicine are the main majors of admission;2) the number of admissions and the actual demand of health professionals of primary health care institutions do not match, the incubation period is too long, there is a shortage of targeted training model, contract signing is difficult to implement, and other problems.Therefore, in accordance with the problems, this paper suggests that, 1) the government should increase the number of admissions to match with the demands;2) a three-year bachelor's degree should be set up in order to shorten the incubation period;3) the training model of targeted admission medical students should be changed;and 4) various powerful measures should be carried out to attract and keep excellent health care professionals.
