Eighty patients with acute exacerbation of chronic obstructive pulmonary disease(COPD)complicated by pulmonary artery hypertention(PAH)were recruited in the study. All patients took conventional western medicine, among them 40 also received injection of Chinese herb medicine Shenxiong(study group)for 14 days. Mean pulmonary artery pressure(mPAP), plasma platelet alphagranule membrane protein(GMP-140), thromboxane B2(TXB2)and 6-keto-prostaglandin F1α(6-K-PGF1α)were measured before and after treatment in both groups. Compared with pretreatment levels and levels in control group mPAP, GMP-140 and TXB2 levels in study group were significantly decreased, while the levels of 6-K-PGF1α were significantly increased. The results indicate that Shenxiong injection may inhibit platelet activation and reduce mPAP.

Objective To evaluate the value of serum CA 19-9 levels in predicting resectability of pancreatic cancer. Methods Serum CA 19-9 levels of 52 patients with pancreatic cancer who were possible to be curatively resected according to the imaging were determined; the gold standard was respectability. An receiver operating characteristic (ROC) curve was constructed for the CA 19-9 levels; the point that lies closest to the upper left-hand comer of the graph is chosen as the cut-off point, the sensitivity, specificity,positive and negative predictive values were calculated. Results There were 29 (55.8%) resectable and 23 (44.2%) inoperable cases of pancreatic cancers. The CA19-9 level in resectable patients was (159.6±170.9)U/ml, and it was (944.4 ±773.4) U/ml in inoperable cases. The area under the ROC curve was 0. 918 ( ＞ 0.9, P ＜ 0.01 ), 95% confidence interval were 0.843 ～ 0.992. The CA19-9 level was (353.2) U/ml according to the cut-off point, the sensitivity and specificity was 93.1% and 78.3%, respectively; positive and negative predictive values was 84. 4% and 90. 0% , respectively. Conclusions Preoperative serum CA19-9 level may be a useful marker for further evaluating the respectability of pancreatic cancer who are possible to be resected according to the imaging studies.

Serial cryostat sections of the celiac ganglion were prepared from 30 guinea pigs.The process of De Da Torre's glyoxylic acid method and different histochmical rea-ctions were performed consecutively on the same section.Under the conditions employ-ed in this experiment,it was shown that the SIF cells,in contrast to the principalneurons,exhibited a more intense reation of adenosine triphosphatase,and a lessintense reaction of monoamine oxidase,lactic dehydrogenase and nonspecific esterase,and a negative reaction of alkaline phosphatase and acetylcholinesterase.The acidphosphatase reaction of most of SIF cells was weak as demonstrated with both theGomori's lead method and the simultaneously coupling method.The SIF cells showedless lipids,nucleic acids and about the same content in tyrosin as compared with theprincipal neurons.These histochemical properties of SIF cells,as well as their morphological charac-teristics of grouping in clusters and surrounding blood vessels,implicated that theyfunction in a different way from that of principal neurons,and probably as endocrineand/or paracrine cells in modulating nervous transmission in the celiac ganglion.

Stereological methods were applied in the qantitative ultrastructural analysis of the chromaffin cells in adrenal medulla of normal adult guinea pigs.The main result includes:(1)The average volume(V)of each cell(714?m~3)and its nucleus (167?m~3);(2)volume density(Vv)of mitochondria(0.082?m~3/?m~3),lysosomes (0.0045?m~3/?m~3),rough-endoplasmic reticulium(0.013?m~3/?m~3),smooth-endopas- mic reticulium including Golgi apparatus(0.024?m~3/?m~3)and granule vesicles (0.23?m~3/?m~3);(3)surface density(Sv)of cell membrane(0.87/?m~2/?m~3)and mitochondrial outer membrane(0.90?m~2/?m~3);(4)numerical density(Nv)of mitochondria(0.89/?m~3),lysosomes(0.11/?m~3)and granule vesicles(59.98/?m~3); (5)the mean diameter of granule vesicles(144 nm),In addition,several small- granule chromaffin cells were quantified separately from the general chromaffin cells.They contain granule vesicles with an average diameter of 97 nm and show a significant difference in surface density of cell membrane(1.54?m~2/?m~3)from that relevant value of general chromaffin cells(P

Objective To evaluate the expression of immunohistochemistry markers p53, p16 and Ki-67 in penile cancer and penile intraepithelial neoplasia (PIN). Methods 33 patients who suffered penile cancer and received organ-sparing surgery from Jan 2004 to Dec 2013 were retrospectively analysed. The expression of p53, p16 and Ki-67 were detected by EnVision/HRP two steps immunohistochemistry. Results The positive expression rates of p53 in normal penile epithelium, low-grate penile intraepithelial neoplasia, high-grate penile intraepithelial neoplasia, well-differentiated squamous cell carcinoma and poor-differentiated squamous cell carcinoma were 0, 16.7 %, 38.5 %, 30.0 % and 66.7 % respectively. The expression rates of p16 were 20.0 %, 50.0 %, 53.8 %, 70.0 % and 33.3 % respectively. The expression rates of Ki-67 were 0, 16.7 %, 61.5 %, 65.0 % and 75.0 % respectively. Conclusions The combined detection of p16 and Ki-67 can contribute to discover PIN and penile carcinoma much more earlier. p53 may be related to the occurrence and development of low differentiated squamous cell carcinoma, and p16 may be related to the occurrence and development of well-differentiated squamous cell carcinoma.

That provincial hospital hosting the local hospital is an important measure to deepening the reform of medical and health system.Advanced hospital management mechanism and excellent technical experts were gradually introduced into the local hospital to establish South Hubei healthcare alliance,and form province-city-county healthcare alliance.In this way,high quality management,manpower and technology resource sink,overall medical technology level achieves good breakthrough.This promotes the rapid development of healthcare alliance member hospitals in the region.
