Pulmonary alveolar proteinosis (PAP) is a rare disease clinically, and at present no western medicine can effectively cure the disease. After the analysis of literatures related to Traditional Chinese Medicine (TCM) for treatment of the disease in the China National Knowledge Internet Database, it was discovered that the syndrome differentiation showed the disease closely associated with phlegm, blood stasis and yin deficiency. In this study, from view point of pulmonary gangrene TCM theory and treatment combined with PAP pathophysiological characteristics, it is emphasized that phlegm accumulation, blood stasis and yang deficiency are the key pathological manifestations of PAP, thus Yanghe decoction, Tounong powder, Kongxian pellet were used for treatment of one such case, the rational thinking in diagnosis and treatment of this patient being consistent with the idea learning western medicine for China use.

The effective quality control in clinical practices is an effective guarantee for the authenticity and scientificity of the findings. The post-marketing reevaluation for traditional Chinese medicines (TCM) focuses on the efficacy, adverse reaction, combined medication and effective dose of drugs in the market by expanded clinical trials, and requires a larger sample size and a wider range of patients. Therefore, this increases the difficulty of quality control in clinical practices. With the experience in quality control in clinical practices for the post-marketing reevaluation for Kangbingdu oral for cold, researchers in this study reviewed the study purpose, project, scheme design and clinical practice process from an overall point of view, analyzed the study characteristics of the post-marketing reevaluation for TCMs and the quality control risks, designed the quality control contents with quality impacting factors, defined key review contents and summarized the precautions in clinical practices, with the aim to improve the efficiency of quality control of clinical practices. This study can provide reference to clinical units and quality control-related personnel in the post-marketing reevaluation for TCMs.

Objective To study the effects of found in inflammatory zone 1(FIZZ1) on the migration of cul- tured mouse vascular smooth muscle cell(VSMC) and the potential mechanism.Methods Using Boyden chamber, immunofluorescence and Western blot,the migratory effects,F-actin content and Akt/Akt1 expression were deter- mined in VSMC after stimulation by FIZZ1.Results FIZZ1 markedly increases the migratory ratio,F-actin con- tent and the Akt1 expression of VSMC.Ly294002,a PI3K inhibitor,attenuated migratory ratio,F-actin content and the Akt1 expression of VSMC promoted by FIZZ1 in a dose-dependent manner (10-30 ?mol/L).Conclusion Our data demonstrated FIZZ1 by activating PI3K/Akt1 pathway induced the expression of F-actin of VSMC,and promoted the migration of VSMC.

In this paper is summarized and classified the recent great progress in the research of spine biomechanics analysis, In addition, the relevant clinical significance as well as some possible research trends of finite element model establishment are also clarified. As a theoretical method, only by close links with clinical practice can finite element analysis really help explain the onset and development of diseases and forecast the curative effects.

Background: Previous study has found that ursolic acid (UA) inhibited the proliferation of gastric cancer cells by the down-regulation of cyclooxygenase-2 (COX-2) expression.However,its molecular mechanism is not fully clear.Aims: To investigate the role of adenosine monophosphate-activated protein kinase (AMPK)/signal transducer and activator of transcription 3 (STAT3)/COX-2 signaling pathway in UA-mediated inhibition of gastric cancer cells proliferation.Methods: AMPK-pLVX,AMPK-shRNA,STAT3-pLVX,STAT3-shRNA plasmids were constructed,and then were transfected into human gastric cancer cell lines SGC-7901 and MKN-45,respectively.Gastric cancer cells were cultured with different concentrations of UA for different times.The expressions of phosphorylated AMPK (p-AMPK),phosphorylated STAT3 (p-STAT3) and COX-2 were measured by Western blotting,and cell proliferation was detected by CCK-8 assay.Results: UA dose-and time-dependently increased p-AMPK expression,inhibited p-STAT3 and COX-2 expressions in SGC-7901 and MKN-45 cells.Knockdown of AMPK blocked UA-induced inhibition of STAT3 phosphorylation and COX-2 expression.Overexpression of STAT3 blocked UA-induced down-regulation of COX-2 expression.Knockdown of AMPK and overexpression of STAT3 blocked UA-induced inhibition of proliferation of gastric cancer cells.Conclusions: UA may inhibit the proliferation of gastric cancer cells via down-regulation of COX-2 expression through AMPK/STAT3 pathway.

OBJECTIVETo investigate the change and correlation of carbon monoxide/heme oxygenase and nitrogen monoxide/nitric oxide synthase system in atherosclerosis and the influence of the two systems on atherosclerotic progress.

METHODSThe rabbits received 1% cholesterol diet (chol group, n = 8), or 1% cholesterol diet plus L-arginine (L-arg group, n = 8) or L-NAME (L-NAME group, n = 8) by drinking water, or 1% cholesterol diet plus heme-L-lysinate (Heme group, n = 8) or ZnPP-IX (ZnPP group, n = 8) by injection in abdominal cavity for 10 weeks.

RESULTSCompared with those in control group, aortic NO production and expression of NOS decreased markedly; while CO production (P < 0.01) and HO-1 activity increased obviously in chol group. The aortic plaques area was (40.2 +/- 8.9)% in chol group. Compared with those in chol group, aortic areas [(26.6 +/- 9.2)%] reduced distinctly in heme group, aortic CO production and NOS activity increased obviously (P < 0.01) in L-arg group. However, compared with those in control group, HO-1 expression and CO production decreased markedly (P < 0.01) in heme group, while they were not different from those in chol group. Compared with those in chol group, aortic cNOS activity and NO production increased obviously and aortic plaques area [(28.1 +/- 7.7)%] greatly reduced (P < 0.01) in L-arg group. However, HO-1 expression and CO production of L-arg group decreased distinctly compared with those of control group, but they were similar to those of chol group. The aortic c-myc and c-fos expressions in both heme group and L-arg group reduced markedly compared with those in chol group, while they were similar to those in ZnPP and L-NAME group.

CONCLUSIONThe reciprocal relationship between heme oxygenase/carbon monoxide and nitric oxide synthase/nitrogen monoxide system in atherosclerosis may play the inhibitory role against atherosclerotic lesion.

Objective To identify and monitor potential risk areas of schistosomiasis in Dongting Lake area. Methods With remote sensing (RS)and geographic information system(GIS) technology, potential risk areas of schistosomiasis in Dongting Lake area were extracted by using spectral characteristics and environmental factors. Based on epidemiological data and land use data, the regional epidemic index and environmental susceptibility index were fused with potential epidemic risk areas in the grid system of Dongting Lake area to form the epidemic risk surveillance map of schistosomiasis in Dongting Lake area from 2006 to 2016. Results From 2006 to 2016, the high risk areas of schistosomiasis epidemic in Dongting Lake area were concentrated in the central and Northern lakeside areas of Changde City (Annual average epidemic index R-=0.330 5, Regional average susceptibility index Y-=2.458 2), the sensitive land types were Lake area (Sensitivity coefficient β=1.236 6), the surrounding area of Datong Lake in Nanxian and Northern Yuanjiang City (R-=0.426 0, Y-=0.836 8), paddy field area (β=0.202 1) and other construction land (β=0.308 0). The extremely high risk areas were concentrated in some lake-facing areas in Jinshi (R-=0.449 1, Y-=3.917 0) and the sensitive land type is woodland(β=1.234 5). The risk of river basin from high to low was respectively the Lishui River, the Yuanjiang River, the Zijiang River and the Xiangjiang River. Conclusions The high-risk and extremely high-risk areas should be the focus of future epidemic control. The snail control and environmental renovation of epidemic-sensitive areas such as sparse woodland, grassland with high coverage, reservoir pits and ponds should be done well in Dongting Lake area.

OBJECTIVETo seek a new method for the categorization of burn severity.

METHODSBurn patients hospitalized in our center from December of 1958 to December of 2004 were enrolled in the study, and they were divided into different age groups according to same mortality, then the patients in each group were subdivided into 4 groups according to the burn severity: i.e., mild burns, moderate burns, severe burns, serious severe burns. The total burn area, the number of cases, the mortality, and the area of DI degree burns were statistically analyzed in each subgroup, and the scope in total burn area and area of III degree burns were taken as standards to define the degree of burns. The logistic regression equation was established with probability of death as the variable, and age, total burn area, burn area of different degrees as concomitant variables to form a logistic regression formula. It was used to predict the probability of death of patients hospitalized in 2005, 50 as to check whether the corresponding indices of these patients were consistant with above standard of categorization into degrees, and to judge hum severity of the patients who had concomitant inhalation injury, severe associated injury, or those with serious disease before burns.

RESULTSThe patients were divided into three groups: less than 2 years of age (including 2 years of age), 2 to 55 years of age(including 55 years of age), and older than 55 years of age groups. The classification standard of burn area was shown in table 2 of the article. The probability of death and corresponding indices predicted hy the logistic regression equation were highly coincident with our standard. Patients with moderate inhalation injury could be regarded as patients with severe or most severe burns, while severity of those with mild inhalation injury could be determined by burn area alone.

CONCLUSIONThe logistic regression equation is a good method to predict the severity of burn patients, with reasonable age specificity grouping, and accurate and practical scoring of division for corresponding burn severity.
