Objective To investigate the prevalence of chronic kidney disease (CKD)and risk factors in the adult population of Tianshan district in Urumqi, Xinjiang. Methods A total of 2131 residents from 4 communities in Tianshan district of Urumqi city were randomly selected using a stratified, multistage sampling. All the residents were interviewed and tested for morning spot urine of albumin to creatinine ratio (ACR) (abnormal ≥ 30 mg/g), morning spot urine dipstick of hematuria ( abnormal ＞3 red blood cells/HP or greater) and pyuria ( abnormal＞ 5 white blood cells/HP) confirmed by microscopy. Renal function was determined with abbreviated MDRD equation [reduced estimated glomerular filtration rate (eGFR)＜60 ml ·min-1 ·(1.73 m2)-1]. The associations of kidney damage indicators with age, gender, hypertension, diabetes mellitus, income,education, cholesterol, triglyceride and smoking were examined. Results Eligible data of 2131 subjects were collected in the study. After the adjustment of age and gender component, the prevalence of albuminuria was found in 2.63％ (95％CI:1.78％-3.48％) of subjects, hematuria in 7.43％(95％CI:6.11％-8.75％) and reduced renal function in 1.72％(95％CI:1.08％-2.35％).Approximately 9.99％(95％CI:8.47％-11.55％) of subjects had at least one indicator of kidney damage. Multivariate logistic regression revealed that albuminuria, hematuria, age and hyperuricemia were independently associated with reduced renal function. Hematuria and reduced renal function were independently associated with albuminuria. Albuminuria, reduced renal function and female were independently associated with hematuria. Conclusion In urban adult population over 35 years old of Urumqi, a big city in western China, the prevalence of CKD is 9.99％, the recognition is 2.44％ and the risk factors of CKD are similar to those of other domestic big cities and western developed countries.

Objective To investigate the characteristics and failure risk factors of sequential high-flow nasal cannula oxygen therapy (HFNC) after weaning from invasive ventilation. Methods The patients who received sequential HFNC after weaning from invasive ventilation admitted to surgical intensive care unit (ICU) of Peking University People's Hospital from June 1st 2016 to May 31st 2018 were retrospectively analyzed. Clinical variables, respiratory therapy parameters, respiratory variables, cardiac variables and outcomes were reviewed and analyzed. Treatment characteristics of HFNC after weaning was analyzed. Patients were divided into HFNC success group and HFNC failure group according to the failure of HFNC, and the differences between the two groups were compared. The independent risk factors of HFNC treatment failure were analyzed by Logistic regression analysis. The value of predictive treatment failure of risk factors and regression models were analyzed by receiver operating characteristic (ROC) curve. Results A total of 99 patients were included, 61 men, and the median age was 67.0 (57.0, 76.0) years old. The medianinitial HFNC flow was 50 (50, 60) L/min, and inspired oxygen concentration (FiO2) was 0.50 (0.40, 0.60). Eighteen patients experienced HFNC failure (18.2%). Compared with the HFNC success group, the sequential organ failure assessment (SOFA) score in the HFNC failure group was higher [4 (3, 5) vs. 2 (1, 3), P < 0.01], B type natriuretic peptide (BNP) before HFNC therapy were significant higher [ng/L: 647.2 (399.2, 1 331.3) vs. 127.2 (55.2, 369.5), P < 0.01], and respiratory frequency (RR) and heart rate (HR) were significant faster, mean arterial pressure (MAP) was significant higher, oxygen index (PaO2/FiO2) was significant lower after 30 minutes HFNC treatment [RR (times/min): 26 (22, 28) vs. 19 (17, 21), HR (bpm): 105 (97, 107) vs. 85 (77, 90), MAP (mmHg, 1 mmHg = 0.133 kPa): 104.3 (101.7, 110.7) vs. 92.3 (88.3, 97.7), PaO2/FiO2 (mmHg): 207.3 (185.8, 402.8) vs. 320.2 (226.2, 361.5), all P < 0.05]. It was shown by multiple Logistic regression analysis that the SOFA score [odds ratio (OR) = 2.818, P = 0.022, β = 1.036], BNP before HFNC treatment (OR = 1.002, P = 0.033, β = 0.002) and HR after HFNC treatment 30 minutes (OR = 1.140, P = 0.032, β = 0.131) were independent risk factors for HFNC treatment failure. It was shown by ROC curve that the area under the ROC curve (AUC) for the prediction of HFNC failure was 0.840, 0.859, 0.860 and 0.962 for SOFA, BNP before HFNC treatment, HR after HFNC treatment 30 minutes, and regression model, all had good forecast values (all P < 0.01). Conclusions HFNC is one of the commonly used oxygen therapy methods in the ICU, but not all patients who are treated as a sequential therapy after invasive mechanical ventilation weaning can benefit from it. SOFA score, BNP before HFNC treatment and HR after 30 minutes HFNC treatment were independent risk factors of HFNC failure. Each independent risk factor and regression model can predict the success of HFNC treatment.

Background Adverse drug reactions (ADRs) to sodium dimercaptosulphonate (DMPS) mercury removal treatment have been reported in occupational mercury poisoning. In recent years, the number of cases of mercury poisoning due to mercury-containing cosmetics has been increasing, and ADRs to the use of DMPS are common in clinical practice. Objective To investigate the occurrence of ADRs and the influencing factors in patients with chronic mercury poisoning and mercury exposure treated with DMPS for mercury removal. Methods Patients treated with DMPS due to mercury poisoning at the Occupational Disease Department of Nanjing Prevention and Treatment Center for Occupational Diseases from June 2017 to December 2023 were included in the study. Information on demographics, baseline characteristics, and treatment regimens was collected at admission. Information on secondhand smoke, place of residence, and blood groups not collected at admission was collected in follow-up. The patients were divided into two groups according to whether ADRs occurred after the use of DMPS and were compared for clinical characteristics, and the influencing factors related to the occurrence of ADRs after DMPS treatment were analyzed by binary logistic regression. Results A total of 72 patients were enrolled in the study, of which 26 reported ADRs during mercury removal. A total of 29 ADRs occurred, mainly rash in 11 cases (37.9%), fever in 5 cases (17.2%), and nausea in 4 cases (13.8%). Most ADRs occurred in the second course (7 cases, 26.9%) and the third course (9 cases, 34.6%). Of the 22 non-menopausal women who experienced ADRs, 13 (59.1%) used DMPS in the week prior to menstruation. The logistic regression analysis showed that smoking (OR=27.911, 95%CI: 2.835, 725.809) and blood type O (OR=6.885, 95%CI: 2.014, 26.896) were associated with elevated occurrence of ADRs after DMPS treatment. Conclusions The probability of ADRs after DMPS treatment is not low, but mild presentations are predominant and resolved with immediate treatment, with a favourable prognosis. The O blood group, smoking individuals, and female patients using DMPS one week before menstruation may be more prone to ADRs.
