Angiogenesis plays a critical role in growth and metastasis of lung cancer.The strongest tumor angiogenesis factor known is the vascular endothelial growth factor (VEGF).Therefore,anti-VEGF therapy which can restrain tumor angiogenesis is an important form of the targeted therapy of lung cancer.The expression of VEGF is also significant to the prognosis of lung cancer.

OBJECTIVE To investigate the susceptible factors and pathogenic bacteria in severe hepatitis and hepatocirrhosis cases infected by complex bacteria.METHODS We reviewed the severe hepatitis and hepatocirrhosis cases admitted to our hospital during 2004-2007,who infected by complex bacteria,to investigate the risk factors and pathogenic bacteria.RESULTS In 216 cases of severe hepatitis and hepatocirrhosis,27 cases were infected by complex bacteria(12.5%).After testing in 66 strains of bacteria,there were 22 strains of Gram-negative bacteria(33.3%),10 strains of Gram-positive bacteria(15.2%),and 34 strains of fungi(51.5%),most of the cases were at terminal stage,with long-term hospitalization,with different underlying diseases,repeated use of broad-spectrum antibiotic and hormone,and invasive operations.All of the factors might induce the complex bacteria infections.CONCLUSIONS The complex bacteria infections in the severe hepatitis and hepatocirrhosis cases are critical and difficult to cure.The underlying diseases should be treated actively;the detection of pathogenic bacteria and drug sensitive test should be carried out;the strict measurement of disinfection and isolation are strongly suggestedto decrease the rate of infection of bacteria and prevent the hazards.

Objective To explore serum TFAR19 activity in preeclampsia patients.Methods 43 of cesarean delivery patients with preeclampsia in the Huairou Maternal and Child Health Hospital of Beijing were recruited and the peripheral venous blood was collected.Among them,severe preeclampsia patients were 18,mild preeclampsia were patients 25.In addition,40 unrelated healthy cesarean puerpera from a routine health survey were enrolled as controls.Enzyme-linked immunosorbent assay(ELISA)was used to detect serum TFAR19 activity in preeclampsia patients.That was absorbancy-A catalytic genera-ted by TFAR19.Results The activity of TFAR19 severe preeclampsia patients,mild preeclampsia patients,and healthy con-trols were 43.56±2.93,33.38±2.32 and 23.63±2.94,respectively.The TFAR19 activity in each group was statistically significant difference (F = 10.65,P <0.01).Compared with healthy controls,the TFAR19 activity in severe preeclampsia group (q=6.384,P <0.001),mild preeclampsia group (q = 3.478,P =0.016)was statistically significant difference.The TFAR19 activity in preeclampsia patients subgroups (severe preeclampsia group,mild preeclampsia group)was statistically significant difference (q = 2.993,P = 0.037).Age between each groups was no-statistically significant difference (F =0.091,P =0.913).Gestation age and neonatal weight betweeneach groups was statistically significant difference (F=4.37, P =0.016;F=35.06,P <0.001).Conclusion The increase of TFAR19 could promote apoptosis,participating the occur-rence of preeclampsia.The content of TFAR19 could be increased with the severity of the preeclampsia.

Objective To perform the research on the domestic hospital marketing. Methods Through deep discussion,data analysis and marketing survey,we conducted a research on the market positioning and marketing strategies for Shanghai Ruijin-Harvard Heart Center which is a Sino-foreign joint venture. Results The demand is much bigger than the current supply in the market for cardiovascular diseases.The establishment of the center meets the demands of the market. Conclusion The center will focus on the adult patients in Shanghai and Yangtze Delta,and combine the external,internal and interactive marketing strategies.It may provide some useful experience for the Chinese hospital management,especially for hospital marketing.

BACKGROUND: How to evaluate the cervical curvature correctly has been a greatly concern of spine surgeons. In recent studies, cervical curvature index(CCI) and cervical spine angle(C2-7) were often used by foreign researchers.OBJECTIVE: Ishihara method and spine angle(C2-7) method were applied to measure the cervical curvature, and the correlation between the two methods was compared as well.DESIGN: An observational controlled trial based on the patients.SETTING: Department of Orthopaedics of Peking Union Medical College Hospital.PARTICIPANIS: Totally 63 cases including 34 male and 29 female patients with cervical spondylopathy were involved in the Department of Orthopaedics of Peking Union Medical Clooefe Hospital from July 2002 to July 2003.METHODS: The 63 cervical spondylopathy patients' cervical spine lateral X-ray films were evaluated.MAIN OUTCOME MEASURES: Main outcomes: ① The patients' CCI and the cervical spine angle; ② Relationship between their CCI and the cervical spine angle. Secondary outcomes: ① Regressive equation derived from their CCI and the cervical spine angle; ② Comparison of CCI and the cervical spine angle between male and female. RESULTS: The CCI(Ishihara method) was averaged 10. 1 (SD, 11.6), and the cervical spine angle(C2 -7) 17. 5 °(SD, 13.5). A highly significant correlation was found between the two indexes( P＜0.01). Sex and age factors were found to be irrelevant to them.CONCLUSION: The CCI (Ishihara method) and the cervical spine angle (C2-7) are significantly correlated with each other.

The effects of dl-Tetrahydropalmatine ( THP ) on the physiologic properties in the auricle of guinea pig and on isoproterenol and calcium-mediated positive chronotropic action in guinea pig atria were studied.30 minutes after THP 52 nM was added, the contractility was decreased to 53+ ( SD ) 17%(P0.05) in the left auricle of guinea pig. Furthermore, the contractility and automaticity of the right auricle were decreased to 48+13% (P

The incidence of adenocarcinoma of esophagogastric junction is increasing worldwide during recent decades.The therapeutic strategies have been transformed from surgery alone to multimodal treatments involing also perioperative chemoradiotherapy.Although there are still many problems on preoperative staging,surgical approach,excisional extent and perioperative chemoradiotherapy regimen,multidisciplinary team collaboration can provide an optimal diagnosis and treatment to achieve the principles of standardization and individualization in malignant tumor,which will prolong the survival and improve the quality of life for every patient.

OBJECTIVE:To systematically review the efficacy of isotretinoin in the treatment of acne vulgaris,and to provide evidence-based reference for clinical treatment. METHODS:Retrieved from PubMed, Cochrane Library, Wanfang, VIP and CJFD,randomized controlled trials (RCT) about isotretinoin (test group) versus viaminati,macrolides,tetracyclines antibiotics and other drugs (control group) in the treatment of acne vulgaris were collected. Meta-analysis was performed by using Rev Man 5.2 software after data extract and quality evaluation by Cochrane 5.1.0. RESULTS:Totally 28 RCTs were enrolled,involving 3 534 patients. Results of Meta-analysis showed,the total effective rate of isotretinoin was significantly higher than viaminati [RR=1.56, 95%CI(1.27,1.91),P<0.001],macrolides[RR=1.44,95%CI(1.31,1.58),P<0.001] and tetracyclines antibiotics [RR=3.05,95%CI(2.29,4.07),P<0.001];improvement of skin lesions scores was significantly better than control group [MD=0.33,95%CI(0.04, 0.62),P<0.05],the differences were statistically significant. Dry lips,cheilitis,dry skin and nasal mucosa and pruritus were the main adverse reactions,and no serious adverse reactions were showed. CONCLUSIONS:Isotretinoin has better efficacy and safety than viaminati,macrolides and tetracyclines antibiotics.

Objective To determine whether or not the bacterial DNA which was detected by PCR comes from viable bacteria.Methods Observe the effection of middle ear effusion(MEE) on DNA viscosity and enzymatic digestion of DNA.Results The middle ear effusion and DNA are stable and DNase 1 rapidly digests DNA,The effusion does not seem to degrade DNA.The middle ear effusion signifcantly inhibits DNase 1.Conclusions Middle ear effusion provides an inhibition of the enzymatic digestion of purified DNA.Thus any DNA found in effusion by PCR techniques could well be fossilized remains and chronic otitis media with effusion may not be the bacterial infection that recent studies have suggested.
