Objective To investigate the relationship between vascular lesion and serological changes in patients with coronary heart disease (CHD) complicated with obstructive sleep apnea hypopnea syndrome (OSAHS). Methods According to the standard, a total of 168 patients of OSAHS complicated with CHD were selected in this study. Those patients were divided into 3 groups according to the apnea hypopnea index (AHI) level:light group (AHI, 5-14/h), moderate group (AHI, 15-30/h) and severe group (AHI,>30/h). Syntax scores were performed on three groups according to coronary angiography results. The data of hemoglobin (Hb), platelet count (PLT), fibrinogen (FIB), D-Dimer (DD), total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), triacylglycerol (TG), alanine aminotransferase (ALT), aspartate transaminase (AST), uric acid (UA), creatinine (Cr) and echocardiographic examination index were collected and analyzed in three groups. Results The Syntax score was significantly higher in severe group than that in mild and moderate groups (P<0.05). There was no significant difference in the Syntax score between mild and moderate groups. The levels of Hb, FIB, LDL, pulmonary arterial pressure (PAP), and right ventricle transverse diameter (RVD) were significantly lower in the mild and moderate groups than those in the severe group (P<0.01). The left ventricular ejection fraction (LVEF) was significantly lower in the severe group than that in the mild and moderate groups (P < 0.01). There were no significant differences in levels of Hb, FIB, LDL, PAP, RVD and LVEF between mild group and moderate group (P > 0.05). Conclusion The serology and cardiac structure can change gradually in severe OSAHS patients, and the coronary artery lesion will be more complex. Therefore, the clinical treatment should pay attention to screening for OSAHS in patients with coronary heart disease.

Objective To investigate the effect of special CT monochromatic images on improving imaging quality in Budd-Chiari Syndrome.Methods 40 patients with Budd-Chiari Syndrome underwent CT venography (CTV)with gemstone spectral imaging (GSI).Using the optimal contrast to noise ratio (CNR)curve of GSI software,the optimal CNR monochromatic images of the infe-rior vena cava and hepatic vein were chosen.The CT value of the intrahepatic segment of inferior vena cava,hepatic vein and the same level liver tissue were measured,and the CT value of the same region were measured on 140 kVp mixed energy images and 70 keV images.CNR on the optimal monochromatic images,the 140 kVp mixed energy images and 70 keV images were calculated respectively,and the image quality of the optimal monochromatic image,the 140 kVp mixed energy images and 70 keV images were subjective scoring.One-way ANOVA was used for statistical analysis using SPSS1 7.0 software.Results The optimal keVs from monochromatic images were distributed at 40 keV (50%)and (5 1 ± 1 )keV (50%)for IVC and 40keV (25%)and (53 ± 3)keV (75%)for HV.The CNR and CT value and subjective score of IVC/HV got from the optimal monochromatic images were signifi-cantly higher than those from 140 kVp mixed energy images and 70 keV images respectively(P <0.01 ).Conclusion The optimal monochromatic images provide higher image quality of IVC and HV in patientswithBudd-Chiari syndrome.

As the specific endangered medicinal plant in Xinjiang, resources and distribution of Ferula sinkiangen-sis are important for biodiversity conservation and sustainable development of Chinese medicine resources. The spa-tial distribution and resources of F. sinkiangensis were researched based on low altitude remote sensing and sample investigation. The results showed that the optimum working time for F. sinkiangensis monitoring by low altitude remote sensing was the nearby 5 hills, which covered about 0.88 km2. It was suggested that the fence area should be expanded for protection. According to the results of low altitude remote sensing, the amount of F. sinkiangensis in yellow (diameter exceeding 0.3 m) was about 3 191. However, the sample investigation on amount of F. sinkiangensis in yellow (diameter exceeding 0.3 m) was about 2 752. The error between them was 14%. The monitoring time and range for F. sinkiangensis by low altitude remote sensing were also ensured. It was concluded that low altitude re-mote sensing had the advantage of quickly receiving distribution situation of F. sinkiangensis, which can effectively evaluate dynamic changes of F. sinkiangensis in Xinjiang.

Objective To investigate the relationship between chronic atrophic antral gastritis and the decrease of somatostatin levels in blood and pyloric glands and adaptable protection ability of gastric mucosa.Methods Gastric mucosa biopsy specimen and blood samples were collected to determine the levels of somatostatin(SST)using radioimmunoassay.Histological changes between pre-and post-treatment were observed under light microscope as well as the changes of uhramicrostrucuture under transmission electron microscope.Distribution of SST in gastric mucosa was studied by immunohistochemical staining and then quantified.Results The quantities of gastric antral D cells of chronic atrophic antral gastritis decrease obviously.SST was mainly distributed in D cells of mucosa pyloric gland crypt.The nucleus of mucus epithelial cells in atrophic gastric antral crypt had SST negative staining.Mitochodria swellen,crista broken,rough endoplasmic reticulum distension,mucus secretory granules decreasing,the nuclear membranes disappearing as well as ehromatin integrating could have been seen in the intracytoplasm of mucus epitheliun cells of chronic atrophic gastric antral gastritis.The average level of SST in blood,epithelium and crypt were obviously reduced comparing to that of in the control group.By immunochemistry staining,the SST level in crypt of atrophic gastric antral gastritis Was significantly reduced comparing to that of in control group.With the level of SST in blood＜10 pg/100μl,the probability ratio of emerging atrophy Was 67.7%.Conclusions In case of no systemic inflammatory reaction state,the decreased ability of human pyloric gland D cell in producing SST not only rehtes obviously with human chronic atrophic antral gastritis but also with the weakened adaptable protection ability of gastric mucosa.

BACKGROUND:Currently, cellular composition and the features of the nucleus pulposus are stil not to be clarified.
OBJECTIVE:To establish the in vitro culture system of rat nucleus pulposus-derived mesenchymal stem cells and to identify their multi-lineage differentiation potential.
METHODS:Mesenchymal stem cells from the nucleus pulposus tissues of Sprague-Dawley rats were cultured in vitro. Then, cells at passage 3 were induced to differentiate into osteoblasts, adipocytes and chondrocytes as experimental group. cells cultured with basic culture medium served as controls.
RESULTS AND CONCLUSION:cells isolated from rat nucleus pulposus could form the sunflower-like colonies and exhibit clone-like growth when they cultured at a low density. cells at passage 3 became homogeneous and exhibited fibroblast-like morphology. After 28 days of osteogenic induction, arizarin red positive signals were detected in the experimental group. The mRNA expressions of RunX2, osteopontin and osteocalcin were significantly increased in the experimental group, compared to the control group (P<0.05). After 21 days of adipogenic induction, oil red-O positive cells were detected in the experimental group. The mRNA expressions of C/EBPαand PPARγ2 were significantly increased in the experimental group, compared to the control group (P<0.05). After 21 days of chondrogenic induction, safranin O/fast green staining was positive in the experimental group. The mRNA expressions of aggrecan and Col2a1 were significantly increased in the experimental group, compared to the control group (P<0.05). Our findings in this study suggested that nucleus pulposus-derived mesenchymal stem cells could be isolated from the Sprague-Dawley rat nucleus pulposus and exhibited clonal-like growth when they were cultured in vitro. These cells were confirmed to have the potential to differentiate into adipocytes, osteoblasts and chondrocytes in vitro.

Based on the investigation of a hospital's grants during 2004-2005 and the authorized during 2002-2005 (385 in total), we tried to find the trends and bias of clinical sciences at present. We analysed on the types of grants (clinical or basic), research objects, experimental methods, discipline involved, modes of cooperation, and background of applicants. A close connection between research and clinical trial, interdisciplinary study, patient-centered practice and international competitions are becoming more and more important. To meet the needs of clinical research, policies and devotions such as technical platforms are needed.
