Objective: To evaluate the quality of Pneumoconiosis Network Direct Report in Sichuan Province in 2006-2016. Methods: download all the pneumoconiosis report cards from the Network Direct Report system. Screen out cards based on the diagnosis time that is between January 1st 2006 and December 31st 2016. Using R 3.4.0 software to analysis the number of missing or repeated cards, time-logical error rates, timeliness, reporting year, reporting intervals to evaluate the quality of Pneumoconiosis Network Direct Report and location distribution. Results: there are 38 855 pieces of Pneumoconiosis report card in total in 2006-2016. 352 pieces of cards were reported twice. 224 cards were missing. 229 cards have time-logical error. The rate of timely reporting for 2006-2016 years was 66.41% (2 5453/38 326) , 67.14% (24 658/36 726) for new cases, 58.87% (783/1 330) for promoting cases and 4.44% (12/270) for deaths. 87.38% (33 490/38 326) patients was reported in the same year. 10 days was needed to finish one report, confirming-filling cost much more time than filling-report (9.865/49.019) . Conclusion the records of pneumoconiosis report cards are much more complete, logical errors are less, and the timeliness was a little bit higher than the average level in China. But it also should be improved. The death cases are difficult to report. It takes longer to diagnose and fill in cards. Improving the timeliness rate can significantly improve the quality of network direct reporting.

Through our pre-investigation and literature analysis, it was found that rhubarb could be categorized into two types, chrysophanol-type and rhein-type, based on the proportion of the two constituents in the total content of anthraquinones after acid hydrolysis. In this paper, the antimicrobial activities of chrysophanol-type and rhein-type rhubarbs against Staphylococcus aureus were compared with microcalorimetric analysis, in order to illustrate the bioactive differentiability between the two chemotypes. For the aim to display the distinction of chrysophanol and rhein percentage in total anthraquinones, the sampling volume was regulated to make the total anthraquinones equivalent, thus, the antimicrobial difference was only attributed to the difference of chemotypes. The results indicated that the antimicrobial difference between the two chemotypes was confirmable labeled at the biothermokinetic parameters of S. aureus growth affected by the rhubarb samples. The growth rate constant (k1) of the first exponential phase for the growth of S. aureus affected by the rhein-type rhubarb was significantly lower than that of chrysophanol-type (P<0.01), which suggested stronger antimicrobial activity of rhein-type rhubarb than that of chrysophanol-type. However, the antimicrobial activities of rhein-type rhubarbs were not positively correlated to the contents of rhein. It suggested that the antimicrobial activity of rhubarb might be related to some unknown components which were of same accumulating pattern of rhein. The findings in present study provided some experimental evidence on categorizing rhubarb into two chemotypes through the difference of antimicrobial activity on S. aureus by microcalorimetric analysis and, further, offered references to revision of the commercial specification of rhubarb from chemical view.

Objective:To investigate the expression of immunoglobulin A (IgA) in human mesangial cells (HMCs).Methods:The HMCs were cultured.The subcellular location of IgA was detected by immunofluorescence staining;the transcripts of Ig α,Ig κ and Ig λ constant region were detected by reverse transcription-polymerase chain reaction (RT-PCR) and further analyzed by DNA sequencing.The expressions of Igαt and Ig λ were detected at transcription level by Western blot after the cytoplasmic protein extraction.The culture supernatant was collected to explore whether IgA could be secreted out of the cell and the protein was further analyzed by mass spectrometry after being purified by affinity chromatography with jacalin-sepharose.The results of DNA sequencing and mass spectrometry were aligned with the mRNA and amino acid sequences in the National Center of Biotechnology Information (NCBI) data-base.Results:By immunofluorescence staining,we detected the presence of IgA heavy chain Ig α,light chain,both Ig κ and Ig λ in expressions of transcripts of Ig α1,Ig α2,Ig κ and Ig λ in the HMCs and the alignment of the sequences of the RT-PCR products with those of the Ig Cα1,Ig Cα2,Ig κ and Ig λ mRNA in the NCBI database exhibited that the similarities were 99％,97％,98％ and 97％,respectively.Western blot showed Ig α and Ig λ expressions in the cell lysate and secretion of Ig α1 and Ig α2 heavy chains in cell culture supernatant.To further explore the protein that secreted into the supernatant,after supernatant affinity chromatography with jacalin-sepharose,the proteins were separated by sodium dodecyl sulfonate-polyacrylamide gel electrophoresis (SDS-PAGE) and the band approximating to 65 000 was cut and sent to mass spectrometry.The results were aligned with the amino acid sequences of Ig α1 and Ig α2 constant region in NCBI database,showing that amino acids between No.52 and No.104,amino acids between No.154 and No.221,amino acids between No.276 and No.327 from Ig Cα1 and amino acids between No.52 and No.113,amino acids between No.151 and No.204,amino acids between No.251 and No.314 from Ig Cα2 were the same with those derived from B cells.Conclusion:Our findings suggested that HMCs could synthesize and secret IgA.

Objective To establish a predictive model for inpatients of cardio-cerebrovascular disease in rural areas of Wugang through time series analysis, and predict the changing trend of cardio-cerebrovascular disease, so as to offer guidance for the health care resources allocation and prevention and control of cardio-cerebrovascular disease. Methods The seasonal autoregressive integrated moving average model (SARIMA) was constructed based on the monthly number of cases of cardio-cerebrovascular disease in rural areas from January 2013 to December 2016 by Stata 14.0 software, and the predictive effect of the model was verified with the monthly number of inpatients of cardio-cerebrovascular disease in 2017. Results The final fitting model of inpatients of cardio-cerebrovascular disease was SARIMA (2, 1, 1)×(0, 1, 0)12. The residual sequence of the model was diagnosed. Results of Ljung-Box Q test showed that the residual sequence was white noise sequence (Q=11.12, P=0.68). In addition, the 2017 forecast was basically consistent with the observations, the overall relative error was around -1.2%. The results showed that the summer was the peak period of cardiovascular and cerebrovascular hospitalization. Conclusion SARIMA model can accurately predict the number of inpatients of cardio-cerebrovascular disease in Wugang, which can provide data support for the hospital administrator to rationally allocate medical resources in the cardiovascular according to the needs of cardio-cerebrovascular treatment in different months.

Purpose: To assess characteristics the application of mobile medication system and medication administration error (MAE) alerts in a general hospital. Methods: The subject hospital adopted a mobile medication system in 2016. All medication administrations in the general wards and ICUs were automatically recorded in real-time using identification barcodes, drug barcodes, and hand-held point-of-care devices. MAE alert logs were recorded from April 1st 2017 to March 31st 2018. For this study analysis was done using Pearson’s chi-squared test for potentially related factors of MAE alerts included administration time, order type, medication route, and length of nurse’s employment. Results: The total number of medications during the period of this study was 3,227,990. Among them, 2,698,317 medication doses were recorded, resulting in the system application rate of 83.6%. The system application rate was significantly correlated with all factors related to potential MAE alters. In this study 23,314 MAE alerts(0.9% of the total medication doses) were identified. The MAE alerts were related to new (OR=2.26, p<.001) and emergency (OR=2.25, p<.001) orders, and administration at a non-standard time (OR=2.032, p<.001). Medication route (p<.001), and nurse’s employment duration(p<.001) were also related. Conclusion A mobile medication system contributes to improving patient safety by preventing potential MAEs. The MAE alerts were related to administration time, order type, medication route, and duration of nurse’s employment. In order to prevent medication administration errors, it is necessary to standardize the process of medication and create an environment in which medication administration can be performed in a planned situation.
