RESUMO

ObjectiveTo analyze the epidemiological features and influencing factors of rabies in Shanxi Province,and to provide evidence to further promote the elimination of rabies in Shanxi Province. MethodsThe incidence data of rabies in Shanxi from 2011 to 2022 were collected and subjected to descriptive analysis. ResultsFrom 2011 to 2022, a total of 348 rabies cases were reported in Shanxi Province, with an average annual incidence of 0.080 3/105. The incidence of rabies showed a downward trend overall. The highest incidence was in August. The cases were mainly farmers, mostly males, and most cases were reported between 50 and 69 years old. The data of cases showed that dogs were the main animals attacking human (93.96%). The incubation period of most cases was 1‒3 months (37.37%).The main exposure site was hand(51.33%). Only 2.66% cases with grade Ⅲ exposure were injected with passive immune agents. ConclusionThe incidence of rabies in Shanxi Province continues to decrease, but there are still loopholes in prevention and control measures. It is necessary to strengthen the management and immunization of dogs,health education, and standardized procedures after exposure to maintain the achievements in the prevention and control of rabies.

RESUMO

【Objective】 To explore the characteristics of esophageal motility and reflux of endoscopic-negative heartburn patients based on the Lyon Consensus Diagnostic Criteria and discuss the differential diagnosis value of the mean nocturnal baseline impedance (MNBI) and the postreflux swallow-induced peristaltic wave (PSPW) index for reflux hypersensitivity (RH) and functional heartburn (FH) patients. 【Methods】 We enrolled 132 patients with heartburn as the main symptom who visited the Gastroenterology Department of our hospital from January 2017 to June 2021, including 24 in the non-erosive reflux disease (NERD) group, 24 in the RH group, and 84 in the FH group. All the patients completed gastroscopy, esophageal high-resolution manometry and 24h-pH impedance monitoring. We analyzed and compared the related indexes of esophageal motility and reflux. The receiver operating characteristic (ROC) curve was used to analyze the esophageal proximal MNBI, distal MNBI, and PSPW indexes for the differential diagnosis of RH and FH. 【Results】 The lower esophageal sphincter (LES) average resting pressure, LES residual pressure and intact relaxation pressure (IRP) in NERD were lower than those in RH and FH (P0.05). When the proximal MNBI, distal MNBI, and PSPW indexes were used alone respectively to diagnose RH, the area under the ROC curve was 0.480, 0.810, 0.682, respectively, with the sensitivities being 87.5%, 100% and 91.7%, and the specificities being 26.2%, 66.7% and 51.2%, respectively. 【Conclusion】 NERD patients have obvious abnormal esophageal dynamics, mainly manifested as LES relaxation, which further aggravates the pathological acid reflux, while patients with RH and FH are mainly exposed to physiological acid or non-acid reflux. In patients with endoscopic negative heartburn, distal MNBI value can improve the clinical diagnosis rate of RH and help distinguish RH from FH.

RESUMO

Objective:To analyze the intensity-modulated radiotherapy (IMRT) process based on the TG100 report, aiming to improve the quality control method and guarantee the safety and quality of IMRT.Methods:Based on the TG100 report, a risk analysis team was established. The flow chart of overall and each sub-step of IMRT was constructed. The failure mode and effect analysis method were adopted to determine all potential error modes in the process. The probability of of the error mode, the probability of being checked out and the severity of the effect of the error mode on the clinical bed were evaluated based on the pre-set scoring standard. The priority value of each error mode was calculated and ranked from high to low priority value. The top 20% is defined as the high-risk error mode, which was analyzed by error tree to improve the quality control method.Results:IMRT consisted of 11 main steps and 41 sub-steps, and 180 failure modes were detected. The priority values were ranged from 30 to 178. A total of 36 high-risk failure modes were found. The top 5 high-risk failure modes (RPN) consisted of setup error (178), electronic portal imaging device (EPID) registration (172), contouring error (166), treatment delivery error (160) and prescription dose error (156).Conclusion:TG100 report is practical and convenient to utilize, which can effectively and systematically improve IMRT process and provide safety and quality assurance of IMRT process.

RESUMO

Objective@#Using three models too estimate excess mortality associated with influenza of Shanxi Province during 2013-2017.@*Methods@#Mortality data and influenza surveillance data of 11 cities of Shanxi Province from the 2013-2014 through 2016-2017 were used to estimate influenza-associated all cause deaths, circulatory and respiratory deaths and respiratory deaths. Three models were used: (i) Serfling regression, (ii)Poisson regression, (iii)General line model.@*Results@#The total reported death cases of all cause were 157 733, annual death cases of all cause were 39 433, among these cases, male cases 93 831 (59.50%), cases above 65 years old 123 931 (78.57%). Annual influenza-associated excess mortality, for all causes, circulatory and respiratory deaths, respiratory deaths were 8.62 deaths per 100 000, 6.33 deaths per 100 000 and 0.68 deaths per 100 000 estimated by Serfling model, respectively; and 21.30 deaths per 100 000, 16.89 deaths per 100 000 and 2.14 deaths per 100 000 estimated by General line model, respectively; and 21.76 deaths per 100 000, 17.03 deaths per 100 000 and 2.05 deaths per 100 000, estimated by Poisson model, respectively. Influenza-related excess mortality was higher in people over 75 years old; influenza-associated excess mortalityfor all causes, circulatory and respiratory deaths, respiratory deaths were 259.67 deaths per 100 000, 229.90 deaths per 100 000 and 32.63 deaths per 100 000, estimated by GLM model, respectively; and 269.49 deaths per 100 000, 233.69 deaths per 100 000 and 31.27 deaths per 100 000, estimated by Poisson model,respectively.@*Conclusion@#Excess mortality associated with influenza mainly caused by A (H3N2), Influenza caused the most associated death amongold people.

RESUMO

Objective To reduce infection risk in hemodialysis patients through analyzing the causes of over stand-ard colony forming unit(CFU)and conducting bacteriological detection of hemodialysis concentrated B solution. Methods According to microbial monitoring results of hemodialysis concentrate B solution in a hospital between November 2011 and May 2012,disinfection frequency of B solution was changed and dispensing container was covered during the process of using,four groups were divided according to different measures (group A disinfected twice a week,covered dur-ing the process of using;group B twice a week;group C once a week;group D once every two weeks),monthly bacte-riological detection of B solution was conducted,condition before and after disinfection of four groups were com-pared.Results Bacterial count in group A,B ,C and D was(25.41 ±15.08),(28.24±28.04),(68.58 ±22.58), and (75.25±26.63)CFU/mL,respectively (F =79.00,P <0.01 );bacterial count of group A,B,and C after in-tervention were all lower than group D before intervention (all P <0.01),bacterial count of group A and B was the lowest.The qualified rate of group A was 100.00%,the unqualified rate of group B,C,and D was 13.95%, 24.24%,and 35.94% respectively(χ2 =28.70,P <0.01 ),the unqualified rates of group A,B,and C after inter-vention were all lower than group D.Conclusion Hemodialysis concentrated B solution should be used within 24 hours after preparing,disinfected twice a week,and covered during the process of using ,so as to control B solution colony number within the standard level.
