Objective To investigate the protective effects of propofol against acute lung injury(ALI) induced by oleic acid.Methods Forty adult male SD rats weighing 250-290 g were anesthetized with intraperitoneal(i.p.)20% urethrane 6 ml?kg~(-1) and tracheostomized.Left common carotid artery and right internal jugular vein were cannulated for BP monitoring and fluid and drug administration.The animals were randomly divided into 5 groups (n=8 each):Ⅰ control group;Ⅱ ALI group in which ALI was induced by oleic acid 250 mg?kg~(-1) i.v.;Ⅲ,Ⅳ and Ⅴ ALI+propofol group in which propofol was continuously infused i.v.at 4, 8 and 16 mg?kg~(-1)?h~(-1) for 4 h immediately after i.v.oleic acid.The animals were killed at 4 h after oleic acid administration.The lungs were immediately removed for(1)examination of ultrastructure of the lung with transmission electron microseope and(2)determination of SOD and MPO activity,content of MDA,level of IL-10 and IL-18 and expression of NF-kB in lung tissue.Results In group Ⅱ intravenous oleic acid produced damage to mitochondria,rough endoplasmic reticulum and osmiophilic multi-lamellar body in type Ⅱ alveolar epithelial cells. Propofol infusion in group Ⅲ,Ⅳ and Ⅴ attenuated the damage to different degrees.In group Ⅱi.v.oleic acid produced significant decrease in MPO and SOD activity and significant increase in MDA content,IL-10,IL-18 and NF-kB expression in lung tissue.Intravenous propofol infusion attenuated the decrease in MPO and SOD activity, increase in IL-18 expression and MDA content and NF-kB expression in lung tissue produced by i.v.oleic acid, but increased IL-10 expression in lung tissue further.The best protective effect was seen in group Ⅳ.Conclusion Propofol i.v.infusion at 4-16 mg?kg~(-1),h~(-1) can inhibit the oxidative response and inflammatory response and down-regulate NF-kB expression in lung tissue.Propofol infusion at 8 mg?kg~(-1)?h~(-1) provides best protective effects.

Objective To explore the correlation between phenotype and genotype of 5α-reductase 2 deficiency. Methods The clinical data of five children with 5α-reductase 2 deficiency were retrospectively analyzed and the relation between their clinical phenotype and genotype were analyzed. Results All of these five children presented small penis and testicular hypoplasia, three of whom had ones similar to the clitoris appearance. The testosterone/dihydrotestosterone (T/DHT) ratio was 10.26-64.99 after human chorionic gonadotropin (hCG) stimulation. Gene detection showed one case had c.680G>A homozygous mutation and the others were compound heterozygous mutations. The mutations were mainly missense mutations, followed by deletion, duplication and nonsense mutations. Conclusion The 5α-reductase 2 deficiency has different degrees of abnormal genital development. Genetic testing contributed to the diagnosis of this disease.

Introduction: Tuberculosis (TB) in internal migrants is one of three threats for TB control in China. To address this threat, a project was launched in eight of the 19 districts of Shanghai in 2007 to provide transportation subsidies and living allowances for all migrant TB cases. This study aims to determine if this project contributed to improved TB control outcomes among migrants in urban Shanghai. Methods: This was a community intervention study. The data were derived from the TB Management Information System in three project districts and three non-project districts in Shanghai between 2006 and 2010. The impact of the project was estimated in a difference-in–difference (DID) analysis framework, and a multivariable binary logistic regression analysis. Results: A total of 1872 pulmonary TB (PTB) cases in internal migrants were included in the study. The treatment success rate (TSR) for migrant smear-positive cases in project districts increased from 59.9% in 2006 to 87.6% in 2010 (P < 0.001). The crude DID improvement of TSR was 18.9%. There was an increased probability of TSR in the project group before and after the project intervention period (coefficient = 1.156, odds ratio = 3.178, 95% confidence interval: 1.305–7.736, P = 0.011). Conclusion: The study showed the project could improve treatment success in migrant PTB cases. This was a short-term programme using special financial subsidies for all migrant PTB cases. It is recommended that project funds be continuously invested by governments with particular focus on the more vulnerable PTB cases among migrants.

[Summary] Microcephalic or Majewski's osteodysplastic primordial dwarfism type Ⅱ ( MOPD Ⅱ) is an extremely rare genetic disease mainly caused by pericentrin ( PCNT) gene mutations. This paper reported one 13-year-old boy, who was admitted because of the slow growth for more than 13 years and deepened skin color over six months. He was diagnosed as MOPD Ⅱ associated with a combination of growth hormone deficiency, type 2 diabetes, hypertension, acanthosis nigricans, multiple café-au-lait spots. On magnetic resonance imaging of brain, no vascular malformations such as aneurysms were shown. There were novel compound heterozygous mutations of PCNT gene in the patient, with the nonsense mutations of c. 502C > T ( p. Gln168 * heterozygous variation) and c. 3103C > T (p. Arg1035* heterozygous variation). His father carried a nonsense mutation c. 3103C > T ( p. Arg1035 *heterozygous variation ) and his mother had a nonsense mutation c. 502C > T ( p. Gln168 * heterozygous variation). After treatment with metformin for three months, his blood glucose returned to normal, and acanthosis nigricans was improved. It seems critical to evaluate the abnormal condition of blood vessels regularly for MOPD Ⅱpatients with PCNT gene mutations.

Objective To compare the sub-cellular proteome of isoniazid ( INH)-resistant Mycobacterium tuberculosis (MTB) with that of sensitive strains for identifying of unique proteins of these strains and discussing their preliminary application in clinical diagnosis. MethodsProteins of cell wall and membrane of 5 INH-resistant strains and 5 INH-sensitive strains were extracted by density gradient centrifugation.The extracts were subsequently analyzed using weak cation exchange (WCX) liquid chromatography ( LC )followed reverse phase (RP) liquid chromatography to compare the sub-cellular protein patterns. A total of 1280 fractions were collected and identified by matrix assisted laser desorption ionization-time of flight-tandem mass spectrometry (MALDI-TOF MS/MS). The Database for Annotation, Visualization and Integrated Discovery (DAVID) was used for cell component and biological process analysis. Normalized Spectral Abundance Factors (NASF) was used for semi-quantity of protein expression. 5 proteins significantly up-regulated in INH-resistant strains and 2 proteins significantly up-regulated in INH-sensitive strains were selected for ELISA analysis with autologous sera respectively. Results A total of 347 proteins were identified. Cell component analysis showed that 58％ proteins were cells well or membrane proteins. Biological process analysis showed that 31％ proteins involved in carboxylic/monocarboxylic acid biosynthetic and metabolic process, 26％ and 15％ proteins involved in organic acid or fatty acid biosynthetic and metabolic process,while 28％ proteins involved in lipid biosynthetic , metabolic, transport and localization process. O-succinylbenzoate synthase, monooxygenase, hypothetical protein Rv2255c, nicotinate-nucleotide--dimethylbenzimidazole phosphoribosyltransferase and membrane phosphatidate cytidylyltransferase cdsA were up-regulated in INH-resistant strains and fractions contained these proteins could elicit specific antibody response with autologous sera. The A450 was higher than that with INH-sensitive sera. The differences between the INH-resistant sera and the INH-sensitive sera were significant ( t = 0.028, 0.044, 0.066, 0.064, 0.083, all P＜0.01 ). Chain A of Rv2002 Gene Product and Chain A of Crystal Structure Of Rv2632c were up-regulated in INH-sensitive strains and fractions contained these proteins could elicit specific antibody response with autologous sera. The A450 was higher than that with INH-resistant sera. The differences between the INH-sensitive sera and the INH-resistant sera were significant (t=0.053, 0.073, both P＜0.05). ConclusionThe combination of density gradient centrifugation and 2D-LC MS/MS technology is useful in enrichment and identification of differential expressed proteins between INH-resistant and INH-sensitive strains at sub-cellular level. It is useful in finding antigens associated with INH-resistant MTB infection, which may prove useful for further study in the mechanism of INH resistant, as well as interaction between MTB and host.
