Objective To evaluate the effectiveness of intervention for health risk factor in hospital employees. Methods This study was carried out among 339 employees of a hospital in Jinan, Shandong Province. Based on the results of Health Risk Appraisal for 14 health risk factors, we designed a 6-months intervention program for the most widely distributed and intervenable health risk factors; and then evaluated the changes of health risk factors after 6 months. Results After 6-month intervention the prevalence of 3 health risk factors decreased (P ＜ 0.05 ): physical inactivity decreased from 57.8% to 38.6%,hyperlipidemia from 9.4% to 5.3%, and unhealthy dietary from 28.9% to 14.8%. Compared with the baseline data, the average number of health risk factors were reduced from 3.10 to 2. 71 ( P ＜ 0. 01 ).Conclusion The intervention can reduce health risk factors effectively.

Objective To evaluate the postoperative related aesthetic parameters and satisfactory degree between CT 3D reconstruction augmentation rhinoplasty with silicone and augmentation rhinoplasty with silicone in adult Han women.Methods Totally 60 adult healthy Han women voluntarily subjected to augmentation rhinoplasty with silicone were randomly divided into groups A and B,30 people each group;Row CT 3D reconstruction augmentation rhinoplasty with silicone was performed in group A,and the augmentation rhinoplasty with silicone in group B;6 months after surgery related data measurement and questionnaire collected,we compared the objective and subjective indicators for the nasal root,dorsum and ministry,respectively.Results There was a difference between group A and group B in the nasorostral angle,the nasal facial angle,the asofrontal angle and the height of the nasal root (89.50±1.40)°,(28.85±2.20)°,(136.26±1.92)°,(6.45±0.27) mm in group A,and (85.40±3.70)°,(26.43±4.39)°,(138.88±4.78)°,(5.28±0.34) mm in group B (all P＜0.05).There was a difference between group A and group B in operation time (51.77 ± 5.35) min vs (29.83±5.76) min (P＜0.05).Conclusions Owing to its preoperative prosthesis design purpose and avoiding local swelling,CT 3D reconstruction augmentation rhinoplasty with silicone has better effects than that of augmentation rhinoplasty with silicone,especially on the nasal dorsum and the nasal root),which can obviously shorten the operation time,and therefore it is more suitable for the defects of the nasal root and dorsum.

Objective To explore the effects of gait training with an alternative gait orthosis (AGO) on the neurogenic bladders of patients with spinal cord injury (SCI). Method Twelve patients with complete SCI at the thoracic and lumbar level were trained for 8 weeks on motor and bladder function. After that, specific gait training with an AGO was given for another 8 weeks. American Spinal Injury Association ( ASIA ) sensation and motor function assessments were done before and after the gait training with the AGO, and bladder capacity, residual urine and urine flow rates were also assessed. Results Compared with pre-treatment there was no significant difference in average ASIA senzsation and motor scores after training, but the maximum rate of urine flow, average urine volume and single urination had significantly increased and residual urine volume had significantly decreased. Conclusions Therapeutic gait training with an AGO can improve bladder function after SCI.

Objective To explore the clinical effectiveness of emergency upper gastrointestinal bleeding channel for patients with acute upper gastrointestinal bleeding(AUGIB)by the inverse probability of treatment weighted(IPTW)method.Methods A retrospective study method was used.The clinical information was collected on 299 AUGIB patients who belonged to the First People's Hospital of Guiyang,where they were admitted from January 2018 to December 2021.AUGIB patients admitted before the establishment of emergency treatment channel(from January 2018 to December 2019)were selected as the routinel group(152 cases),while AUGIB patients admitted after the establishment of emergency treatment channel(from January 2020 to December 2021)were selected as the channel group(147 cases).IPTW was used to balance multiple confounding variables[gender,age,history of previous underlying diseases,history of non-steroidal anti-inflammatory drug(NSAID)administration,personal history,Glasgow-Blatchford score(GBS),different bleeding etiologies,etc.],a consistent distribution of confounding variables among the groups was achieved after IPTW treatment.The difference of clinical treatment effects between the routine group and the channel group was performed,including time to hemostasis,recurrent bleeding rate,volume of blood transfusions,length of hospital stay,hospitalization cost,intensive care unit(ICU)transfer rate,and mortality etc.were compared.Results After IPTW,the confounding variables were well-balanced between groups.The time to hemostasis[hours:7.90(5.36,11.42)vs.9.92(6.25,18.15)],recurrent bleeding rate[23.1%(34/147)vs.40.1%(61/152)],length of hospital stay[days:8.00(7.00,10.34)vs.9.00(7.00,13.00)],ICU transfer rate[8.8%(13/147)vs.17.7%(27/152)],and mortality[0.7%(1/147)vs.4.5%(7/152)]in channel group were significantly lower than those in the routine group(all P<0.05).There were no significant difference in transfusions volume and hospital cost between channel group and routine group[transfusions volume(U):2(0,4)vs.2(0,4),hospitalization cost(ten thousand yuan):1.35(1.03,2.00)vs.1.16(0.71,2.29),both P>0.05].Conclusion The emergency treatment channel can reduce the recurrent bleeding rate,ICU transfer rate,and mortality rate,shorten the time of hemostasis and length of hospital stay,and has a good treatment effect.

Objective:To evaluate the prevention and control effect of coal-burning-borne endemic fluorosis in Ankang City of Shaanxi Province, so as to provide a scientific basis for formulating precise prevention and control strategies in the future.Methods:From 2019 to 2023, according to the requirements of the "Monitoring Program of Shaanxi Province for Coal-burning-borne Endemic Fluorosis (2019 Edition)", full coverage monitoring was carried out in all affected villages in seven affected counties under the jurisdiction of Ankang City. Using the simple random sampling method, 30 households in each affected village were selected to investigate the use of improved stoves and the formation of health-related behaviors. All children aged from 8 to 12 in the village were examined for the prevalence of dental fluorosis. At the same time, 6 monitoring villages were selected in 2019, and 8 monitoring villages were selected in 2023 to collect real-time urine samples from children aged 8 - 12 for determination of urinary fluoride level. The evaluation for control and elimination of disease areas was carried out in accordance with the "Evaluation Approach for Control and Elimination of Priority Endemic Diseases (2019 Edition)".Results:From 2019 to 2023, a total of 203 880 households were monitored, the rate of qualified improved stoves and the correct use rate of qualified improved stoves were more than 95.00%. The utilization rate of improved stoves decreased from 16.34% (6 584/40 290) in 2019 to 8.89% (3 706/41 700) in 2023, showing a decreasing trend year by year (χ 2trend = 3 400.37, P < 0.001). The utilization rate of clean energy increased from 82.52% (33 247/40 290) in 2019 to 94.36% (39 350/41 700) in 2023, showing an upward trend year by year (χ 2trend = 7 506.09, P < 0.001). The correct drying rate of corn and pepper for human consumption were 100.00%. A total of 455 327 children aged 8 - 12 were examined, and 2 301 cases of dental fluorosis were diagnosed, with a detection rate of 0.51%. Children with dental fluorosis were mainly extremely mild and mild, accounting for 94.87% (2 183/2 301). The dental fluorosis index was 0.012, indicating no trend of fluorosis prevalence. The detection rate of dental fluorosis in children decreased from 0.81% (765/94 537) in 2019 to 0.24% (204/86 066) in 2023, showing a declining trend year by year (χ 2trend = 375.45, P < 0.001). The geometric mean urinary fluoride levels of children aged 8 to 12 in 2019 and 2023 were 0.48 and 0.42 mg/L, respectively, with statistically significant differences between groups ( Z = - 3.05, P = 0.002). As of 2023, 1 390 affected villages had met the elimination criteria. Conclusions:The prevention and control of coal-burning-borne endemic fluorosis in Ankang City has achieved remarkable results, with all seven affected counties reaching the elimination standard.

Objective:To learn about the changes of the condition of coal-burning-borne endemic arsenism, the use of improved stoves and the formation of health-related behaviors in Shaanxi Province, and evaluate the effect of prevention and control measures.Methods:From 2015 to 2020, according to the "Implementation Plan for Monitoring Coal-burning-borne Endemic Arsenism in Shaanxi Province", regular field surveys were carried out in 4 natural villages, 2 counties in Ankang City and Hanzhong City, Shaanxi Province, to learn about the basic prevention and control situation in the monitoring village. Using the simple random sampling method, 10 families in each village were selected to investigate the use of stoves and the formation of health-related behaviors, and 5 of these families were selected to collect coal samples for arsenic content determination in accordance with the "Determination of Arsenic in Coal" (GB/T 3058-2008). According to the "Diagnosis of Endemic Arsenicosis" (WS/T 211-2015), the condition of the people exposed to high arsenic coal in the monitoring village was investigated. Urine samples of 30 adult patients (half males and half females) with arsenic poisoning were collected, the content of arsenic in urine was determined by the "Urine-Determination of Arsenic-Silver Diethyldithiocarbamate-Triethanolamine-Spectrophotometric Method" (WS/T 28-1996).Results:A total of 240 households were monitored in the past 6 years, and the quality conformance and correct utilization rates of improved stoves in the households monitored in the disease areas remained at 100.00% in 2018 - 2020. The utilization rate of clean energy increased from 75.00% (30/40) in 2015 to 100.00% (40/40) in 2018 - 2020 (χ 2trend = 25.5, P < 0.001). The 73.75% (177/240) of households using a variety of clean energy. From 2018 to 2020, the correct drying, storage and pre-processing washing rates of corn and pepper continued to reach 100.00% (40/40). The arsenic content of coal ( n = 120) in the disease areas was (118.09 ± 57.91) mg/kg, ranging from 16.70 to 280.94 mg/kg. The detection rate of arsenic poisoning decreased from 6.34% (231/3 646) in 2015 to 2.90% (109/3 754) in 2020 (χ 2trend = 121.8, P < 0.001), and no skin cancer or Bowen's disease was detected. The geometric mean of arsenic content in urine ( n = 720) was 0.038 1 mg/L, ranging from 0.000 5 to 0.312 9 mg/L. Conclusions:The condition of coal-burning-borne endemic arsenism areas in Shaanxi Province has reached the national elimination standard. The quality and correct utilization rate of improved stoves and the rate of using clean energy have increased. The healthy-related behaviors the people in the endemic areas have been basically formed. The prevention and control work has achieved good results.

Objective:To evaluate the predictive value of proximal ureteral diameter (D1)to distal ureteral diameter (D2)ratio (DDR) for impacted stones in the middle and upper ureter.Methods:The clinical data of 173 patients with middle and upper ureteral calculi admitted to the Third Hospital of Shanxi Medical University from January 2014 to November 2021 were retrospectively analyzed. There were 75 males and 98 females, with the median age of 56.0 (51.0, 62.0) years old and median body mass index of 26.1 (24.8, 27.2) kg/m 2. The imaging data of the patients were analyzed. The impacted stones were defined as the inability of the contrast agent to pass through the site of obstruction when intravenous urography or CT urography was performed, resulting in the inability of the ureter to visualize normally in parts below the site of obstruction. D1 was defined as the proximal ureteral diameter at the lower pole of the kidney on horizontal CT images. D2 was defined as the ureteral diameter 3 cm from the calculi. The stone diameter, stone CT value, D1, D2, and DDR were compared between impacted stone group and non-impacted stone group. Univariate logistic regression analysis was used to analyze the different indicators. Random number table was used to divide the training set and validation set according to the ratio of 7∶3. Through least absolute shrinkage and selection operator(LASSO) regression analysis, the independent influencing factors were obtained and the nomogram model was established (Model 1). Receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to verify the predictive efficacy of the model, and the other three effective models (Model 2-4) were constructed by stepwise multivariate logistic regression. The deLong test was used to compare whether there was a significant difference in the AUC between Model 1 and the other three models, and the net benefit of patients was analyzed by clinical decision curve analysis(DCA). Results:In this study, 64 cases (37.0%) were impacted ureteral calculi and 109 cases (63.0%) were non-impacted ureteral calculi, and there were significant differences in diameter[7.8(6.2, 8.8)mm vs. 6.3(5.2, 8.1)mm] , CT value[878.5(763.8, 940.5)HU vs.764.0 (613.0, 854.0) HU], D1[11.1(8.9, 14.9) mm vs. 9.1(7.1, 10.8) mm], D2[4.1(3.1, 4.9) mm vs. 5.0(4.1, 5.9) mm] and DDR[3.1(2.3, 3.9) vs. 1.8(1.4, 2.4)] between the two groups( P < 0.05). The results of univariate logistic regression analysis showed that stone diameter ( OR = 1.333, P < 0.001), CT value ( OR = 1.002, P=0.002), D1 ( OR = 1.146, P<0.001), D2 ( OR = 0.652, P < 0.001) and DDR ( OR = 2.995, P<0.001) were the influencing factors of impacted stones. The training set and validation set included 122 cases and 51 cases, respectively, without significant differences in their image characteristics and outcomes ( P > 0.05). The results of LASSO regression analysis showed that λ corresponding to the simplest result in the optimal range was 0.0908, and three variables were included at this time, and the influencing factors of impacted stones were stone diameter (coefficient 0.0700, OR = 1.073), CT value (coefficient 0.0003, OR = 1.001) and DDR (coefficient 0.5960, OR = 1.815). Moreover, Model 1 was established. According to the model fitting results, ROC curves were plotted, and the AUC of Model 1 was 0.862, and the AUCs of Model 2-4 were 0.859, 0.762, and 0.793, respectively. After deLong test, there was no significant difference between Model 1 and Model 2 ( Z = 0.248, P = 0.804). The AUC of Model 1 was superior to that of Model 3 ( Z = 2.888, P = 0.004) and Model 4 ( Z = 2.321, P = 0.020). The DCA suggested that Model 1 could improve the net benefit rate by up to approximately 21% of patients. Conclusions:DDR is the influencing factor of impacted ureteral calculi, and the model constructed by DDR, stone CT value and stone diameter can effectively predict the probability of impacted ureteral calculi in the middle and upper ureter.

Objective:To provide a promising and optimal laboratory susceptibility-testing method for the clinical usage of antibiotic (polymyxin), four susceptibility-testing methods were performed and the broth microdilution (BMD) was chosen as the gold standard.Methods:A total number of eighty-eight nonduplicate clinical Enterobacteriaceae specimes were collected from January to December of 2019 in the First Affiliated Hospital, Fujian Medical University. Among the clinical specimens, of which six strains were positive for mcr-1. The minimal inhibitory concentration (MIC) of polymyxin of the clinical specimens were examined by the following methods: (1) broth microdilution, (2) colistin broth disk elution, (3) Vitek-2?, (4)BD PhoenixTM,(5)commercial broth microdilution. With BMD as reference, essential agreement (EA), categorical agreement(CA), very major error(VME) and major error (ME) of polymyxins for different methods were analyzed. The Kappa-consistency testing, paired Chi-square testing and the Spearman-rank correlation testing were used to analyze the consistency between the four antimicrobial susceptibility testing methods and the gold standard.Results:Taking broth microdilution as reference, the EA of colistin broth disk elution, Vitek-2?, BD PhoenixTM, commercial broth microdilution were 94.32% (83/88), 92.05% (81/88), 90.90% (80/88), and 96.59%(85/88), respectively. The CA of all the four methods were 100% (88/88). No VME and ME were recorded for four methods. Moreover, the consistency between four susceptibility testing methods and the gold standard is acceptable (Kappa values=1, P<0.001, McNemar test P=1 and r>0.5, P<0.05). Conclusions:In the present work, four susceptibility testing methods all met the standards recommended jointly by the Clinical and Laboratory Standards Institute and European Committee on Antimicrobial Susceptibility Testing, of which the performance of the commercial broth microdilution and CBDE fared relatively well. Thus, these four methods could be routinely used in clinical microbiology laboratory of our hospital for colistin and polymyxin B susceptibility testing.
