Objective: To investigate the characteristics and HIV confirmed positive status among individuals attending HIV voluntary counseling and testing (VCT) clinics in Inner Mongolia Autonomous Region, so as to provide the basis for enhancing interventions targeting high-risk populations for AIDS. Methods: Demographic information, reasons for consultation, consulting institutions, and HIV antibody testing data of individuals attending VCT clinics in Inner Mongolia Autonomous Region from 2019 to 2023 were collected through the VCT database of the Chinese Center for Disease Control and Prevention. The characteristics of individuals attending VCT were described. Factors affecting HIV confirmed positive among VCT clinic attendees were analyzed using a multivariable logistic regression model. Results: A total of 249 919 individuals attended VCT clinics in Inner Mongolia Autonomous Region from 2019 to 2023, including 128 069 males (51.24%) and 121 850 females (48.76%). The majority of attendees were aged 25-<35 years, accounting for 92 445 cases (36.99%). Among them, 785 cases were confirmed as HIV positive, with a positivity rate of 0.31%. Multivariable logistic regression analysis revealed that males (OR=4.787, 95%CI: 3.562-6.434), 45-<65 years of age (45-<55 years, OR=7.723, 95%CI: 1.786-33.406; 55-<65 years, OR=7.689, 95%CI: 1.757-33.653), being unmarried (OR=2.143, 95%CI: 1.580-2.906), junior high school education or below (OR=1.147, 95%CI: 1.042-2.430), having the history of high-risk behaviors or exposure risks (commercial heterosexual behaviors, OR=2.717, 95%CI: 1.707-4.324; non-commercial non-fixed heterosexual behaviors, OR=5.421, 95%CI: 3.763-7.809; homosexual behaviors, OR=70.774, 95%CI: 48.409-103.473; having an HIV-positive spouse/fixed partner/mother, OR=100.024, 95%CI: 62.490-160.100; drug injection, OR=5.366, 95%CI: 2.213-13.014), and seeking general hospitals or traditional Chinese medicine hospitals (OR=1.973, 95%CI: 1.650-2.360) were associated with a higher risk of HIV confirmed positive. Conclusions HIV confirmed positive among individuals attending VCT clinics in Inner Mongolia Autonomous Region is associated with gender, age, marital status, educational level, reasons for consultation, and consulting institutions. It is recommended to strengthen health education and targeted interventions for high-risk populations to reduce the risk of HIV infection.

Poisoning induced by inhalation of hydrogen chloride has significant effects on the respiratory system. It can cause severe pulmonary edema and acute respiratory distress syndrome (ARDS) in the early stage, and even death in critical cases. As a novel treatment for ARDS, the efficacy of sivelestat sodium in infection-induced ARDS has been widely verified, but its application in ARDS caused by chemical poisoning is still scarce in literature. Here we report a case of ARDS induced by hydrogen chloride inhalation which was successfully treated with sivelestat sodium and conventional treatment.

Objectives To understand the quality status of disinfection products in the market in Shaanxi Province, and to provide a basis for taking targeted management measures. Methods From 2020 to 2023, in accordance with the national disinfection product management regulations and standards, the physicochemical and microbial tests of disinfection products in Shaanxi Province were carried out through supervised sampling, and the test results were analyzed according to the active ingredients, illegal addition, stability, and bactericidal or bacteriostatic performance. Results The overall qualification rate of the active ingredient content of disinfectants sampled in Shaanxi Province was 90.48%, with the lowest qualification rate in 2023 (84.38%). The overall qualification rate of quantitative sterilization test of disinfectants was 90.12%, showing a decreasing trend year by year (P=0.272). The overall qualification rate of anti-bacterial products was 88.59%, and the bactericidal test results of 20 antibacterial products were all qualified. The overall qualification rate of bacteriostatic performance testing for bacteriostatic products was 86.17%, with the pass rate of bacteriostatic product germicidal efficacy testing of different components in descending order being quaternary ammonium salt/silver ion > guanidine > others > lysozyme, and there was statistically significant difference (P=0.004). The detection rate of illegal additives in antimicrobial products was 7.07%, with the main detection indicators being miconazole nitrate, clobetasol propionate, and dexamethasone acetate. Conclusion The qualified rate of disinfection products in Shaanxi Province is relatively high, but there is a downward trend. It is necessary to continue to strengthen the daily supervision and product testing of disinfection product manufacturers, and promote the continuous improvement of disinfection product quality.

To investigate the strain composition and drug resistance characteristics of G +(Gram positive cocci) cocci causing bloodstream infections in the People′s Hospital of Inner Mongolia Autonomous Region in recent years and provide a basis for the empirical and rational use of drugs for the prevention and treatment of bloodstream infections caused by G +cocci. The strain composition and drug-resistant characteristics of G +cocci isolated from positive blood culture specimens sent to various departments of the Inner Mongolia Autonomous Region People′s Hospital from January 2015 to December 2022 were retrospectively analyzed, and the higher detection rates of Staphylococcus hominis and Staphylococcus epidermidis, Enterococcus faecium and Enterococcus faecalis, and methicillin-resistant Staphylococcus aureus (MRSA) and methicillin-sensitive Staphylococcus aureus (MSSA) were examined. MRSA and methicillin-sensitive Staphylococcus aureus (MSSA) were comparatively analyzed for resistance. The resistance data were analyzed by Whonet 5.6 statistical software, the significance of difference was analyzed by SPSS 22.0 software, and the resistance rate was compared by χ2 test. The results showed that 1 209 strains of G +cocci, in terms of the composition ratio, from high to low, were mainly human staphylococci (32.5%,393/1 209), Staphylococcus epidermidis (27.8%, 336/1 209), Staphylococcus aureus (14.9%,180/1 209) and Enterococcus faecalis (10.6%, 128/1 209). Among them, the detection rate of methicillin-resistant Staphylococcus aureus (MRSA) (42.8%, 77/180) was lower than that of methicillin-resistant coagulase-negative staphylococcus (MRCNS) (71.5%, 608/850); and among enterococci, the detection rate of Enterococcus faecalis (71.5%, 128/179) was much higher than that of Enterococcus faecalis (28.5%, 51/179). For drug resistance, the resistance rate to five commonly used antimicrobial drugs, ciprofloxacin, levofloxacin, moxifloxacin, clindamycin and tetracycline, was higher in Staphylococcus hominis than in Staphylococcus epidermidis ( χ2=7.152-64.080, P<0.05); however, for the aminoglycoside antimicrobial drug gentamicin, the rate of resistance in Staphylococcus humanus was lower than in Staphylococcus epidermidis, and the difference was statistically significant ( χ2=11.895, P<0.05); no strains resistant to linezolid and vancomycin were found in both. Comparison of the resistance rates to seven antimicrobial drugs, gentamicin, rifampicin, ciprofloxacin, levofloxacin, moxifloxacin, clindamycin and tetracycline, was significantly higher in MRSA than in MSSA ( χ2=6.169-56.941, P<0.05); however, the resistance rate to cotrimoxazole, MRSA (15.6%, 12/77) was significantly lower than that of MSSA (35.3%, 36/102), and the difference was statistically significant ( χ2=5.155, P<0.05); MRSA and MSSA resistant to linezolid and vancomycin were not found. The resistance rate of Enterococcus faecalis to penicillin G and ampicillin was much higher than that of Enterococcus faecalis, and the difference was statistically significant ( χ2=22.965, P<0.05), and vancomycin-resistant enterococci (VRE) were not found. In conclusion, for staphylococci, except for individual antibiotics, S.hominis and MRSA were more resistant to most antimicrobial drugs than S. epidermidis and MSSA, showing a multidrug-resistant pattern. For enterococci, except for penicillin G and ampicillin resistance rate, Enterococcus faecalis is much higher than Enterococcus faecalis, the rest of the antimicrobial drugs did not see a significant difference, in addition to vancomycin-resistant enterococci were not detected. Clinicians should pay great attention to the monitoring data of multidrug-resistant G +cocci isolated from blood cultures to provide a basis for empirical and rational use of drugs in the clinic, to effectively prevent and reduce the incidence of bloodstream infections caused by G +cocci.

Objective:To investigate the Correlation between ADC combined with serum C-reactive protein (CRP) and delayed encephalopathy after carbon monoxide poisoning (DEACMP), It provides scientific basis for early prediction of DEACMP.Methods:According to the design principle of case-control study, the data of acute carbon monoxide poisoning (ACOP) patients admitted to Shandong Provincial Hospital from December 2017 to December 2021 were retrospectively selected. Among them, patients with DEACMP were selected as the case group, without DEACMP were used as the control group. Univariate and multivariate analyses were performed on the two groups. Receiver operating characteristic curve (ROC) was used to evaluate the diagnostic efficacy of ADC combined with CRP as a combined predictor for disease.Results:A total of 89 patients with ACOP were included, including 33 patients with DEACMP and 56 patients without DEACMP. There were no significant differences in gender, age, smoking, drinking, and underlying diseases (hypertension, coronary heart disease) between groups ( P>0.05). Logistic regression analysis showed that white blood cell count (WBC) ( OR=1.64, 95% CI: 1.19-2.26, P=0.003), CRP ( OR=1.22, 95% CI: 1.03-1.45, P=0.019) and ADC value of central semiovale white matter ( OR=0.99, 95% CI: 0.98-1.00, P=0.010) were associated with DEACMP in patients with ACOP. The ROC curve results showed that the area under the ROC of ADC combined with CRP in the center of semiovale was 0.765 (95% CI: 0.656-0.845), the specificity was 87.9%, the sensitivity was 23.2%, and the cut-off value was 3.5°. Conclusions:WBC, CRP and ADC value of central semiovale are independent factors for DEACMP. ADC value of central semiovale combined with CRP has more clinical value in the early diagnosis of DEACMP. For ACOP patients with DEACMP triggering factors, the diagnosis and treatment awareness of early screening of brain magnetic resonance imaging should be strengthened to avoid DEACMP.

Objective:To analyze the application effect of health failure mode and effect analysis (HFMEA) model in patients with artificial airways in the cardiovascular surgery intensive care unit (CSICU) by establishing a HFMEA project team, and to develop targeted improvement measures and processes.Methods:The patients undergoing cardiovascular surgeries and with established artificial airways in the Shandong Provincial Hospital Affiliated to Shandong First Medical University were recruited from October 2021 to March 2022. The enrolled patients were divided into the conventional management group and the HFMEA model management group according to random number table method. The conventional management group applied the conventional procedures for monitoring the air bag pressure. The HFMEA model management group used the HFMEA model to implement and improve the airbag pressure monitoring process. The efficacy of HFMEA was assessed by comparing the incidence of ventilator-associated pneumonia (VAP), the pass rate of airbag pressure monitoring, the duration of endotracheal intubation and the length of CSICU stay between two groups. The practicability of HFMEA model was evaluated by analyzing the theoretical assessment scores and practical skill scores of nurses and their satisfaction scores with HFMEA.Results:Compared with the conventional management group, the patients in the HFMEA mode management group had a significantly higher rate of passing airbag pressure monitoring [94.99% (2 994/3 152) vs. 69.97% (1 626/2 324), P < 0.01], shorter duration of endotracheal intubation and length of CSICU stay [duration of endotracheal intubation (hours): 6 (7, 12) vs. 6 (8, 13), length of CSICU stay (hours): 40 (45, 65) vs. 41 (46, 85), both P < 0.05], but the incidences of VAP between the two groups were similar. The theoretical assessment scores and practical skill scores of nurses were significantly higher (theoretical assessment score: 44.47±2.72 vs. 37.59±6.56, practical skill score: 44.56±2.66 vs. 40.03±4.32, total score: 89.03±3.07 vs. 77.63±9.56, all P < 0.05) in the HFMEA mode management group. And the satisfaction scores with airbag pressure management were also significantly higher in the HFMEA mode management group (7.72±1.11 vs. 6.44±1.32, P < 0.05). Conclusions:The application of the HFMEA can improve the airbag pressure measures and standardize the monitoring procedures in patients with artificial airways, and reduce the risk of clinical nursing. It is safe and effective for patients with invasive mechanical ventilation in the CSICU.

Objective:To investigate the clinical efficacy of distal pancreatectomy with celiac axis resection(DP-CAR).Methods:A total of 89 consecutive patients (50 males and 39 females) who were diagnosed with pancreatic body cancer and underwent DP-CAR in Pancreas Center,First Affiliated Hospital of Nanjing Medical University between September 2013 and June 2022 were retrospectively reviewed. There were 50 males and 39 females,with age( M(IQR)) of 63(12) years(range:43 to 81 years). Perioperative parameters,pathology results and follow-up data of these patients were analyzed, χ2 or Fisher′s test for categorical data while the Wilcoxon test for quantitative data. Survival results were estimated by the Kaplan-Meier survival method. Results:Among 89 cases,cases combined with portal vein-superior mesenteric vein or organ resection accounted for 22.5% (20/89) and 42.7% (38/89),respectively. The operative time,blood loss and postoperative hospital stay were 270 (110) minutes,300 (300) ml and 13 (10) days,respectively. The overall morbidity rate was 67.4% (60/89) while the major morbidity was 11.2% (10/89). The increase rate in transient liver enzymes was 42.7% (38/89),3.4% (3/89) for liver failure,53.9% (48/89) for clinically relevant postoperative pancreatic fistula,1.1% (1/89) for bile leak,3.4% (3/89) for chylous leak of grade B and C,11.2% (10/89) for abdominal infection,9.0% (8/89) for postoperative hemorrhage of grade B and C,4.5% (4/89) for delayed gastric emptying,6.7% (6/89) for deep vein thrombosis,3.4% (3/89) for reoperation,4.5% (4/89)for hospital mortality,7.9% (7/89) for 90-day mortality. The pathological type was pancreatic cancer for all 89 cases and pancreatic ductal adenocarcinoma made up 92.1% (82/89). The tumor size was 4.8(2.0) cm, ranging from 1.5 to 12.0 cm. The number of lymph nodes harvested was 14 (13)(range:2 to 33),with a positive lymph node rate of 13.0% (24.0%). The resection R0 rate was 30.0% (24/80) and the R1 (<1 mm) rate was 58.8% (47/80). The median overall survival time was 21.3 months (95% CI: 15.6 to 24.3) and the median disease-free survival time was 19.1 months (95% CI: 11.7 to 25.1). The overall survival at 1-year and 2-year were 69.60% and 39.52%. The median survival time of 58 patients with adjuvant chemotherapy was 24.3 months (95% CI: 17.8 to 32.3) while that of 13 patients without any kind of adjuvant therapy was 8.4 months (95% CI: 7.3 to 22.3). Seven patients accepted neoadjuvant chemotherapy and there was no significant morbidity among them,with a resection rate of R0 of 5/7. Conclusion:DP-CAR is safe and feasible for selective cases,which could be more valuable in improving long-term survival when combined with (neo) adjuvant therapy.
