Objective To investigate the effects of hyaluronan (HA) and CD44 on airway mucous hypersecretion,and explore the molecular mechanism of activation of epidermal growth factor(EGF)/epidermal growth factor receptor(EGFR) signal transduction pathway by signal factors. Methods BEAS-2 B airway epithelial cells were cultured in vitro,and were stimulated by neutrophil elastase(NE).Reactive oxygen species(ROS)scavenger(DMTU),hyaluronidase(Hase),CD44 antibody and tissue kallikrein(TK)inhibitor(PI)were served as interventional factors,and control group(serum free culture),NE stimulation group(50 nmol/L NE),DMTU+NE group(20μmol/L DMTU+50 nmol/L NE),DMTU+Hase+NE group(20 μmol/L DMTU+10μg/mL Hase+50 nmol/L NE),CD44Ab+NE group(5 μg/mL CD44Ab+50 nmol/LNE)and PI+NE group(1 00μg/mL PI+50 nmol/L NE)were established.The expression of mucin(MUC)5AC mRNA was detected by RT-PCR,the expression of MUC5AC and EGF protein was determined by ELISA,and the expression of phosphorylated epidermal growth factor receptor(p-EGFR)protein was analysed by Western blotting. Results The expression of MUC5AC,EGF and p-EGFR protein and MUC5AC mRNA in NE stimulation group was significantly higher than that in control group(P<0.01),the expression in DMTU+NE group was significantly lower than that in NE stimulation group(P<0.01),the expression in MTU+Hase+NE group was significantly higher than that in DMTU+NE group(P<0.05 for MUC5AC and p-EGFR protein and MUC5AC mRNA,and P<0.01 for EGF protein),the expression in CD44Ab+NE group and PI+NE group was significantly higher than that in NE stimulation group(P<0.05 for MUC5AC and p-EGFR protein and MUC5AC mRNA,and P<0.01 for EGF protein). Conclusion NE up-regulates the expression of MUC5AC gene via ROS/HA/CD44/TK/EGF/EGFR signal transduction pathway in airway epithelial cells.

Retrovirus (RV), a major pathogen in acute gastroenteritis in children that may lead to severe disease and heavy burdens on national economy. There is no speciifc drug treatment for the gastroenteritis caused by RV, and vaccine has been identiifed as the most effective intervention to control the associated disease burden. The RV vaccine showed differential effects on different RV infection. In China, epidemiology of RV is more complex hence demands more epidemiologic studies. In this article, we will review the epidemiology of RV in China and further discuss the importance of generalized RV vaccine.

Objective To explore the issues of everyday expenses list used in the cadre wards and find out countermeasures for the purpose of reducing medical disputes and improving the patients’satisfaction.Method Seventy-four patients admitted in our department from July to September 2012 were set as control group,where an investigation was conducted to find out the issues in the practical use of every expenses list and corresponding measures were worked out and used in observation group,which included 78 patients admitted in the department from October to December 2012.The two groups were compared in terms of self-paid articles, re-recording of missed expenses,failure to timely refunding,charging by other means,disagreement on curative nursing items and unclear items for charging.Result The observation group was significantly better than the control in self-paid articles,re-recording of missed expenses and failure to timely refunding(all P<0.05).Conclusions There are some issues in the use of everyday expenses list in the cadre wards.We should take corresponding countermeasures to ensure the interests of the hospital and the patients and the enhanced degree of patients’comfort.

Objective:To investigate the effects of fluvastatin on high-sensitivity c-reactive protein( hs-CRP) , tumor necrosis fac-tor-α(TNF-α), urine albumer excretion rate (UAER)and serum creatinine (Cr) in the patients with early diabetic nephropathy. Methods:Totally 69 patients with early diabetic nephropathy were randomly divided into the observation group with 34 cases and the control group with 35 cases. The observation group was treated by low-protein diet plus fluvastatin, and the control group was treated by low-protein diet only. The course of treatment was 8 weeks. Totally 65 nondiabetic persons were selected as the normal group, and the levels of TNF-α, hs-CRP, UAER, ALT and Cr were detected before and after the treatment. Results:The levels of TNF-α, hs-CRP and UAER in the observation group and the control group were significantly higher than those in the normal group(P<0. 05);the lev-els of ALT and Cr showed no significant differences (P>0. 05). Compared with that before the treatment, the level of UAER was de-creased significantly in the control group after the treatment (P<0. 05), and the levels of TNF-α and hs-CRP showed no significant differences after the treatment (P>0. 05). In the observation group, the levels of TNF-α, hs-CRP and UAER were all decreased sig-nificantly after the treatment (P<0. 05). Conclusion:UAER, hs-CRP and TNF-α are closely connected with diabetic nephropathy. Fluvastatin can decrease the levels of TNF-α, hs-CRP and UAER. Low-protein diet plus fluvastatin is effective and safe in the treat-ment of early diabetic nephropathy, and the efficacy is superior to that of low-protein diet only.

Objective To observe the clinical effects of short-term intermittent ganeiclovir treatment on infants with cytomegalovirus (CMV) hepatitis. Methods The clinical data of infants with CMV hepatitis were analyzed retrospectively. The liver functions including total bilirubin (TBil), direct bilirubin (DBil), alanine aminotransferase (ALT), aspartate aminotransferase (AST) and γ-glutamyltransferase (γ-GT) of the patients in treatment group (85 cases) and control group (37 cases) were collected before and after treatment. Meanwhile, the side effects of ganciclovir during treatment were observed. The measurement data were compared by analysis of variance and numeration data were compared by chi-square test. Results After short-term intermittent ganciclovir treatment in treatment group, TBil level was decreased from (109.1±677.8)μmol/L to (62.9±68.1)μmol/L (F=15.34,P<0.01); ALT level was decreased from (160.2±395.3) U/L to (68.1±56.0) U/L (F=4.73, P<0.05). In control group, TBil level was decreased from (94.9±647.4)μmol/L to (49.2±631.5) μmol/L (F=14.80, P<0.01) ; while ALT level was decreased from (131.6±206.2) U/L to (55.3±631.2) U/L (F=3.50, P=0.067). The readmission rate in control group was significantly higher than that in treatment group (21.6% vs 10.6%). Only one case (0.8%) received three times of intermittent ganciclovir treatment. The longest hospitalization time was six weeks. Conclusions Short-term intermittent ganciclovir treatment may be more suitable for infants with CMV hepatitis. There is no obvious side effect observed during the treatment and the hospitalization time can be shortened.

Objective To investigate the expression and clinical significance of Claudin-4 in human se-rous ovarian cancer.Methods 43 cases of serous ovarian cancer from Oct.2008 to May 2014 were studied.Re-al-time quantitative PCR( qRT-PCR) was applied to detect mRNA expression of Claudin-4 in serous ovarian cancer ( n=43 ) in comparison to the corresponding tumor-adjacent tissues.The protein expression of Claudin-4 was measured by immunohistochemistry( IHC) .Results mRNA and protein expression level of Claudin-4 was signif-icantly higher in serous ovarian cancer tissues than in adjacent normal tissues(P<0.05).The high expression of Claudin-4 protein was also associated with large tumor size, lymphatic metastasis, and advanced TNM stage( P<0.05 ) .Conclusions The expression of Claudin-4 is significantly higher in serous ovarian cancer tissues than in the adjacent normal tissues, and it is associated with clinicopathological features.Claudin-4 may become a new marker in early diagnosis and biological target therapy.

Objective To observe the manifestation of fundus angiographs of polypoidal choroidal vasculopathy (PCV). Methods Twelve PCV patients involved 7 males and 5 females aging from 40 to 69 year old (average 56.4). Fundus examination, fundus fluorescein angiography (FFA), and indocyanine green angiography (ICGA) were performed on 12 patients (12 eyes) with PCV, out of whom 5 underwent optical coherenece tomography (OCT). Results In 12 eyes, deep and (or) superficial hemorrhage and yellow hard exudations were found, including orange-red lesions in 6 and pre-retinal hemorrhage in 2. The results of FFA discovered orange-red spotty fluorescence in 6 eyes and choroidal vascular network in 4 eyes. At the late phase, leakage of polypoidal hyperfluorescence spot in all of the eyes except 2 without leakage were found. The images of ICGA showed typical dotted or clustered polypoidal hyperfluorescence in 12 eyes at the late phase. OCT disclosed protrusion of the retinal pigment epitelium (RPE) with a bumpy surface at polypoidal structure in 4 eyes and no change in 1 eye. Conclusions PCV mainly affects the elderly persons and mostly on unilateral eyes. Macular hemorrhage, serous RPED, and (or) neuroepithelial detachment with yellow hard exudations are the main manifestations. Branching choroidal vascular net with ployplike terminal anourysmal dilations can be discovered in FFA and ICGA.

BACKGROUND:Biological dressings with sealing negative pressure drainage can promote the healing of acute and chronic wounds. OBJECTIVE:To observe the clinical effects of biological dressings with sealing negative pressure drainage in repair of diabetic foot ulcer. METHODS: Totaly 40 patients with diabetic foot ulcer were enroled and al underwent debridement or debridement plus skin grafting treatment. Wound treatment methods were selected according to the wiling of patients. Patients in the test group (n=20) underwent polyvinyl alcohol hydration algae salt bubble wound dressings with sealing negative pressure drainage. Patients in the control group (n=20) underwent regular wound dressing treatment. At the 7th RESULTS AND CONCLUSION: The visual analog scale scores, blood sedimentation, C-reactive protein levels in the test group were lower than those in the control group (P < 0.05). The wound healing time in the test group was shorter than that in the control group (P < 0.05), and the patient satisfaction was higher in the test group than the control group (P < 0.05). There was no significant difference in economic costs between the two groups. There was no local or systemic toxicity, alergy and other adverse reactions in the test group. These results day of repair, visual analog scale scores, blood sedimentation, C-reactive protein levels, wound healing time, patient satisfaction and economic costs at the termination of the treatment in these two groups were compared. demonstrate that polyvinyl alcohol hydration algae salt bubble wound dressings with sealing negative pressure drainage in repair of diabetic foot ulcer is safe and effective to promote wound healing and reduce local inflammatory response.
