Objective To study the effect of pentoxifylline (PTX) on acute lung injury (ALI) in murine sepsis induced by intra abdominal infection. Methods Wistar rats were subjected to sepsis caused by cecal ligation and puncture (CLP), and animals were randomly divided into normal controls ( n =6), sepsis group ( n =18), and PTX treated group ( n =18). Pulmonary biopterin, nitric oxide (NO) levels, and pulmonary myeloperoxidase (MPO) activities were measured, guanosine triphosphate cyclohydrolase Ⅰ (GTP CHI), inducible nitric oxide synthase (iNOS), and tumor necrosis factor ? (TNF ?) mRNA expression were determined.Results Early treatment with PTX significantly decreased pulmonary MPO activities and TNF ?mRNA expression at 2 hours after CLP. Meanwhile, pulmonary biopterin, NO, GTP CHI, and iNOS mRNA expression levels were much lower in the treatment group than those in the non treatment group ( P

0.05).CD34 showed widespread expression in cholangio-carcinoma tissues,but limited in normal bile duct,which showed significant difference(P

Objective To investigate the role of calcineurin(CaN)in inflammatory pain in rats.Methods Seventy-five male Harlan-Sprague-Dawley rats,weighting of 200-300 g were randomly divided into 3 groups (n=25): group control (group C),group CFA (complete Freunds adjuvant) (group F) and group CaN+CFA (group NF).100 μl CFA were injected on the right hind claw preparaing for inflammatory pain models in groups F and NF,100 μl saline were injected on the right hind claw in group C.CaN 10 U was intracerebroventricular injected 1 d before CFA injection in group NF.Paw withdrawal thermal latency (PWTL) were measured in 30 min prior to (T0),0.5 h (T1),1 h (T2),2 h (T3) and 4 h (T4) after injection.The expression of CaN and nuclear factor kappa B (NF-κB),IL-1β,TNF-α and IL-10 in spinal cord were measured at each time point.Results The PWTL was significantly shorter at T2-T4 in group F,at T3,T4 in group NF than that at T0and in group C (P<0.05);The PWTL at T2-T4 in group NF was significantly longer than that in group F (P<0.05).CaN protein expression in spinal cord at T1-T4 in group F,at T2-T4 in group NF was significantly lower than that of T0 and in the group C,NF-κB p65 protein expression was significantly higher than that of T0 and in the group C (P<0.05).CaN gene and IL-10 protein content at T2-T4 in groups F and NF were significantly lower than that of group C and at T0,NF-κB gene and IL-1β,TNF-α protein content was significantly higher than that of group C and at T0 (P<0.05).CaN protein and CaN gene expression,IL-10 protein content in spinal cord tissue at T1-T4in group NF was significantly higher than that of group F,NF-κB p65 protein and NF-κB gene expression and contents of IL-1β,TNF-α protein were significantly lower than that of group F (P<0.05).Conclusion CaN adjusts pro-inflammatory and anti-inflammatory cytokines by reducing NF-κB and inhibiting the process of inflammatory pain in rats.

Objective To evaluate the role of spinal CX3C chemokine receptor 1 (CX3CR1) in inflammatory pain and the relationship with calmodulin (CaM)-calmodulin-dependent protein kinaseⅡ(CaMKⅡ) signaling pathways in mice.Methods Ninety-six pathogen-free healthy male C57BL6 mice,weighing 25-27 g,were divided into 3 groups using a random number table:control group (group C,n=30),inflammatory pain group (group IP,n=36) and CX3CR1 antagonist group (group CA,n=30).Inflammatory pain was induced by injecting complete Freund′s adjuvant (CFA) 50 μl into the plantar surface of right hind paws in IP and CA groups,while the equal volume of normal saline was given instead in group C.In group CA,CX3CR1 antagonist (diluted to 1 μg/5 μl in phosphate buffer solution) was intrathecally injected at 1 h before CFA injection.The thermal paw withdrawal latency (TWL) was measured at 30 min before CFA injection (T0) and 30 min,1 h,2 h and 4 h after CFA injection (T2-4).The animals were then sacrificed,and the spinal cord was removed for determination of the expression of phosphorylated CaMKⅡ (p-CaMKⅡ),phosphorylated cyclic adenosine monophosphate response element-binding protein (p-CREB) and c-fos (by Western blot) and expression of CaMKⅡ,CREB and c-fos mRNA (using real-time polymerase chain reaction).Immunofluorescence was used to determine that p-CAMKⅡ was expressed in microglia.Results Compared with group C,the TWL was significantly shortened at T2-4,and the expression of p-CaMKⅡ,p-CREB and c-fos protein and mRNA was up-regulated at T1-4 in IP and CA groups (P<0.05).Compared with group IP,the TWL was significantly prolonged at T2-4,and the expression of p-CaMKⅡ,p-CREB and c-fos protein and mRNA was down-regulated at T1-4 in group CA (P<0.05).p-CaMKⅡ was co-expressed with the microglial specific biomarker.Conclusion CX3CR1 is involved in the development and maintenance of inflammatory pain through activating CaM-CaMKⅡsignaling pathways in mice.

Objective To evaluate the clinical efficacy and safety of injection azithromycin in the treatment of the acute bacteria pneumonia of infant. Methods A randomized controlled open trial was carried out. Erythromycin as a controll drug was compared the clinical efficacy and safety with azithromycin as a test drug. Results In azithro-mycin group,the clinical effective rate was 90.6% ;the fully recovered rate was 75.5%. While those of erythromycin group were 68.0% ,36.0% respectively. The incidence of adverse reaction was 9.3% and 30.4% respectively in two groups. Conclusion Injection azithromycin of new macrofides type is a kind of effective and safe anti-bacterial drug.

Objective To assess the predictive value of serum uric acid levels to the incident nonalcoholic fatty liver disease(NAFLD)in a cohort of healthy population. Methods A prospective cohort study of NAFLD incidence was conducted in Xinjiang province, from 2012 to 2014. A cohort study was performed on 2 207 subjects with no evidence of fatty liver disease by liver ultrasound and with no major risk factors for liver disease at baseline. All participants were interviewed to carry out the epidemiological questionnaire survey, physical examination, abdominal ultrasonography, as well as blood biochemistry measurements. The hazard ratios of NAFLD were compared among groups with different uric acid levels. All subjects were classified according to serum uric acid (within normal range grouped by quartile: Q1-Q4 group; above the normal range: Q5 group). Results NAFLD was newly diagnosed in 13.72% subjects within the 3-year period. The incidence of NAFLD was increased with elevated serum uric acid quartiles(P<0.01). In multivariate logistic regression, after adjustment for gender, age, race, metabolic syndrome and its components, OR for incident fatty liver in Q2 to Q5 of serum uric acid concentration as compared to Q1 were 2.509, 3.172, 3.392, and 4.041 respectively. Conclusion Elevated serum uric acid concentrations may predict NAFLD in the subjects for a regular health checkup.

Our country has been using maturity grading method, which was proposed by Grammum in 1979, to evaluate the placental function. However, this method is subjective to consequence because it totally depends on the observation and experiences of clinicians. With the development of ultrasound technology, therefore, we reviewed more novel applications in other aspects of placenta (such as blood flow, vascularization, etc). Over the past years, scholars in the world have done a lot of research around these topics. In this review we introduce placental maturity grading with B-mode ultrasound, placental vascularization qualitative and quantitative analysis with three-dimensional Doppler ultrasound and placental volume measurement, respectively.

Objective To evaluate the diagnostic value of endoscopic ultrasonography(EUS) in the eminence lesions of gastrointestinal tract.Methods The clinical data of 420 patients with gastrointestinal eminence lesions subsequently received EUS were analyzed.Results In 420 cases,235 cases lesions were located in the stomach,129 cases in the esophagus,29 cases in the duodenum and 27 cases in the colon.Occurred in the wall itself of the digestive tract lesions was 85.00％ (357/420),and 73.10 ％(307/420) of submucosal neoplasm,and gastrointestinal stromal tumor,leiomyoma or leiomyosarcoma was seen [60.24％ (253/420)].Lesions was not found in the digestive tract wall external oppression and lesions accounted for 14.52％(61/420),external lesions and infiltrated digestive tract was 0.48％(2/420).Conclusions EUS is an ideal diagnostic modality in distinguishing different layers of the wall of the gastrointestinal tract,and thus of important value in precise localization of lesions beneath the mucosa.And be able to hint the nature of the lesion.Meanwhile,this may be associated with colonic mucous membrane structure.
