Objective:To detect the change of composition of immune cells in the spleen of miR-126 knockdown(miR-126KD) mice and preliminarily explore its significance .Methods: The expression level of miR-126 in spleens of miR-126KD mice was deter-mined by Realtime PCR.And the total number of splenocytes was calculated.The pathologic morphology change of the spleen was observed by HE staining.And the changes on proportion of DCs ,macrophages cells ,γδ T cells and NK T cells,CD3+T cells and its subgroup ,as well as CD19+B cells in spleens of miR-126KD mice were analyzed by Flow cytometry and calculated respectively.The level of phosphorylated AKt and NF-κB was analyzed by Western blot assay.Results:Compared with those of WT mice ,the expression level of miR-126 decreased obviously ( P<0.05 ) and the total number of cells increased obviously in spleen of miR-126 KD mice ( P<0.05).Moreover,the pathologic morphology of miR-126KD mice was significantly changed.The proportion and number of NK T cells in the inherent cells were significantly increased ( P<0.05 ) , but the proportion of Mφcells were significantly decreased ( P<0.05 ) . Meanwhile,the proportion and number of CD3+T cells and CD4+T cells in the adaptive immune cells were significantly increased (P<0.05),while the total number of CD19+B cells were significantly decreased (P<0.05).Last,the level of phosphorylation Akt and NF-κB increased obviously in spleen of miRNA-126 knockdown mice.Conclusion: Change obviously on the composition of immune cells subsets in the spleen of miRNA-126 knockdown mice ,which it may be related to the altered level of phosphorylated AKt and NF-κB and provides a preliminary experimental basis for the further exploring the roles of miR -126 in immune response.

To explore the relationship between serum 1,25(OH)2D3 and oxidative stress in patients with diabetic nephropathy (DN).The serum levels of 1,25(OH)2D3 in DN patients were significantly lower than those in DM and healthy controls.And the 1,25(OH)2D3 level was negatively correlated with advanced oxidation protein products ( AOPP ) , reactive oxygen species ( ROS ) and positively correlated with superoxide dismutase (SOD) in DN patients.1,25(OH)2D3, low density lipoprotein-cholesterol (LDL-C), body mass index ( BMI) , serum creatinine and age were associated with the level of oxidative stress in DN patients.With the progression of CKD , the serum levels of AOPP and ROS increased significantly while those of SOD and 1,25(OH)2D3 decreased markedly.

Objective To measure the titers of varicella live attenuated vaccines ( VarV) during the process of transportation and storage in different seasons and communities of Minhang Distract, Shang-hai, to evaluate the operation of cold chain system and the thermal stability of vaccines and to provide refer-ences for the management, introduction, research and development of vaccine in future.Methods Four communities with high outbreak rates of varicella during 2012 to 2013 and four communities with low out-break rates were randomly selected from 13 communities in Minhang District, Shanghai.The titers of VarVs were detected by using the quantitative plaque assay before and after 30 days of storage in November 2013 and February, May, August 2014.Results The overall rate of qualified VarVs was 90.63% with a geo-metric mean titer (GMT) of 3.67 (LgPFU/0.5 ml).96.88%of the VarVs produced by company C met the quality standard with a GMT of 3.89 ( LgPFU/0.5 ml) followed by those produced by company B with a rate of 91.67%and a GMT of 3.75 ( LgPFU/0.5 ml) .The rate of qualified VarVs produced by company A was the lowest, which was 80.00%, with GMT of 3.29 (LgPFU/0.5 ml).There were significant differences in the rates of qualified VarV among the three companies (χ2=8.288, P=0.016).The rate of qualified vac-cines in communities close to the Shanghai Minhang Center for Disease Control and Prevention ( Minhang CDC) was 91.67%, while 100%of the vaccine samples collected form the communities at a middling dis-tance from or far from the Minhang CDC met the quality standard.No significant difference in the rate of qualified vaccine was found among the three types of communities (χ2=3.441, P=0.179).The quarterly rates of qualified vaccines produced by B and C companies were 100%except for the third quarter.The rates of qualified vaccines produced by A, B and C companies in the third quarter were respectively 70.00%, 66.67%and 87.50%.No statistical differences in the quarterly rates of qualified vaccines were found among the three companies (χ2=1.25, P=0.7412;χ2=6.545, P=0.088; χ2=6.194, P=0.103).No statistical differences in the rates of qualified vaccines before and after 30 days of storage were found among the three companies (χ2=0.625, P=0.347;χ2=0.000, P=1.000;χ2=2.065, P=0.492).Conclusion A well-managed and-operated cold chain system was implemented in Minhang District in the storage and transport of vaccines as well as other related links.The thermal stability of vaccines produced by company C was better than those of the other two companies.A surveillance for the titers of vaccines produced by com-pany A should be strengthened.

Objective:To explore the barriers of online consulting services by dental specialist nurses, so as to provide theoretical basis for constructing an online service model of dental specialist nurses.Methods:This study was a qualitative study. Based on the theoretical domains framework (TDF), an interview outline was developed. From January to February 2023, purposive sampling was used to select 12 nurses from Shanghai Stomatological Hospital who participated in online consulting services for dental specialist nursing as the research subject, and semi-structured interviews were conducted on the nurses. According to the relevant fields of TDF, the transcribed data was sorted and the interview data was analyzed using the Colaizzi 7-step analysis method.Results:A total of three themes and eight sub-themes were extracted, including ability barriers (low level of dental knowledge, lack of written communication skills), environmental barriers (insufficient special publicity and promotion, inadequate standardized service standards and processes, limited online consulting platform functions, distributed appointment resources), and goal barriers (low sense of professional value, incomplete performance evaluation system) .Conclusions:The relevant management departments of hospitals should standardize the management system of online consulting services by dental specialist nurses and optimize the process of online consulting services by dental specialist nurses. At the same time, dental specialist nurses should enhance their abilities, provide high-quality online consulting services for patients, and improve patients ' satisfaction with online consulting.

Objective To investigate the correlation between smoking, white blood cell counts, and serum bilirubin levels in male radiation workers, and to explore the role of systemic inflammatory response in the changes of serum bilirubin level induced by smoking. Methods Occupational health examination data of 1 320 male radiation workers in a medical institution was collected. Linear regression analysis method was used to analyze the correlations between smoking and white blood cell counts, between smoking and serum bilirubin levels, and between white blood cell counts and serum bilirubin levels. Results There was a significant positive correlation between smoking and white blood cell counts (P< 0.05). Both smoking and white blood cell counts were significantly negatively correlated with serum bilirubin levels (P < 0.05). However, after adjusting the white blood cell counts, the correlation between smoking and serum bilirubin levels was not statistically significant (P > 0.05). By dividing white blood cell counts into two groups, an inverse correlation was found between smoking and serum bilirubin levels in the high white blood cell count group (P < 0.05). Conclusion Serum bilirubin may be an effective indicator of early health damage caused by smoking in male radiation workers. Smoking may induce inflammatory reaction, thus deplete serum bilirubin and cause its levels to drop.
