ABSTRACT

Objective:To analyze the supply efficiency and influencing factors of medical and health services in 31 provinces in China from 2011 to 2020, providing reference for rational allocation of medical and health resources and improving service efficiency.Methods:The data related to the input-output indicators of China′s medical and health services from 2011 to 2020 were collected from China Health Statistical Yearbook, China Statistical Yearbook and China Social Statistical Yearbook. Data envelopment analysis was used to calculate the static efficiency of China′s medical and health service supply, the Malmquist index method was used to analyze the dynamic efficiency of China′s medical and health service supply, and the Tobit model was used to analyze the factors affecting the efficiency. Results:In 2020, the comprehensive efficiency of medical and health service supply in 15 provinces (Tianjin, Shanghai, Zhejiang, etc.) was 1.000, and the scale benefit remained unchanged. The comprehensive efficiency in 16 provinces (Heilongjiang, Jilin, Inner Mongolia, etc.) was less than 1.000. Among them, 15 provinces showed a decreasing scale benefit, while 1 province showed an increasing scale benefit.From 2011 to 2020, the total factor production efficiency index of China′s healthcare service supply increased from 0.988 to 1.036. The factors affecting the efficiency included number of people with a college degree or above per 10 000 people, the utilization rate of hospital bed rate, population density, asset liability ratio, and average length of stay ( P<0.05). Conclusions:In recent years, the efficiency of healthcare service supply in China showed a growth trend featuring regional differences and multiple influencing factors. It is suggested to further narrow the regional differences of the efficiency, reasonable control the scale of medical institutions, optimize medical service technology and management levels, shorten the average transfer day and improve bed utilization to improve the overall efficiency of medical and health service supply.

ABSTRACT

Objective:To explore the isolation and culture methods of mouse parietal epithelial cells (PECs) of Bowman′s capsule, so as to provide a cell tool for further study.Methods:Mouse renal corpuscles were isolated by cell sieving combined with magnetic separation. After primary culture, identified parietal epithelial cells were induced to differentiate into podocytes. Immunofluorescence staining, real-time quantitative PCR and Western blotting were used to detect specific markers of parietal epithelial cells and podocytes.Results:Primary cultured PECs grew like paving stone and expressed Claudin-1 (PECs specific marker), CD133 (stem cell marker) and CD24 (stem cell marker), without the expression of tubular epithelial cell proteins, mesangial cell and podocyte specific proteins. Cultured to 6 generations in vitro, the PECs still expressed Claudin-1, CD133 and CD24. After incubated with differentiation medium, PECs were able to express podocyte markers WT-1 and Synaptopodin. Conclusion:The renal corpuscles are extracted by cell sieving combined with magnetic separation, and the mouse PECs successfully cultured in vitro can be induced to express podocytes′ markers.

ABSTRACT

Objective:Evaluate the application of Fourier transform infrared spectroscopy in the identification of homology of carbapenem-resistant Escherichia coli(CREC). Methods:A total of 26 carbapenem-resistant Escherichia coli strains were isolated from 9 provinces in China in 2018. The 900-1 200 cm -1 was selected as a spectral region for the Euclidean distance calculating and average linkage clustering between all isolates.The single nucleotide polymorphism (SNP) was analyzed by whole genome sequencing (WGS). Results:Twenty-six CREC strains were divided into 14 infrared spectros copy(IR) types by FTIR. The same IR type belonged to the same sequence type type.Compared with cluster analysis based on WGS, the consistency of FTIR cluster analysis was 92.3% (24/26).Conclusions:FTIR presented excellent performance in identification of homology of CREC.Besides, with the advantages of simple operation and rapid acquisition of results, FTIR may be a useful tool in clinical labs.

ABSTRACT

Objective To explore the association of fibroblast growth factor-23 (FGF23) with abdominal aortic calcification(AAC) and adverse outcomes in maintenance hemodialysis patients.Methods One hundred and fourteen cases of MHD patients were collected prospectively.Serum intact FGF23 was detected by ELISA.Abdomen lateral plain was used as a criteria to determine the abdominal aortic calcification and the abdominal aortic calcification score was counted.Logistic regression analysis was used to determine the risk factors of AAC.Kaplan-Meier analysis was applied to compare the survival rate among different groups and COX regression analysis was used to determine the association of FGF23 and mortality in MHD patients.Results Seventy-six patients present abdominal aortic calcification.The median of AACS was 4.0(0.0,11.0).The median level of FGF23 was 7277.4(2535.0,9990.8) pg/ml.The median follow-up duration was 72.0(67.8,72.8) months.During the follow-up,22 patients (19.3%) died of all-cause death and 17 cases (14.9%) died of cardiovascular diseases.Serum FGF23 level was positively correlated with AAC (r=0.285,P=0.002).Logistic regression analysis showed that longer age (OR=1.059,95%CI:1.020-1.100,P=0.003) and dialysis vintage (OR=I.009,95%CI 1.000-1.017,P=0.039),smoking history (OR=3.010,95%CI 1.177-7.696,P=0.021) and higher FGF23 level(OR=2.831,95%CI 1.010-7.937,P=0.048) were independent risk factors of moderate to severe AAC in MHD patients.Kaplan-Meier survival curves showed that the patients with AACS≥ 5 had significantly higher all-cause mortality(P=0.028) and CVD mortality (P=0.035) than those with AACS < 5.However,the Kaplan-Meier analysis showed no significant difference regarding the level of serum FGF23 with the all-cause and CVD mortality.Cox regression demonstrated that FGF23 was not associated with increased mortality risk,neither in crude nor in multivariate adjusted models.Conclusions Abdominal aortic calcification had a high prevalence in MHD patients.The all-cause and CVD mortality was higher in patients with moderate to severe AAC.FGF23 was an independent risk factor of moderate to severe AAC,but it can't yet be a predictor for the allcause and CVD mortality of MHD patients.

ABSTRACT

Objective To determine the relationship between serum soluble Klotho (sKL) level and adverse outcome in maintenance hemodialysis (MHD) patients.Methods One hundred and twenty nine cases of MHD patients were collected prospectively.Serum sKL was detected by ELISA.Abdomen lateral plain was used as a criterion to determine the abdominal aortic calcification.The abdominal aortic calcification score (AAC) was calculated.Cox regression analysis was used to determine the risk factor of cardiovascular death (CVD) in MHD patients.Kaplan-Meier showed the relationship between sKL and CVD in MHD patients.Results There were 27 cases (20.9%) of allcause death and 19 cases (14.7%) of cardiovascular death.The median sKL was 612.6(379.2-816.6) nig/L,and log[iPTH] was an independent factor of sKL concentration.Low sKL had high AAC and CVD death rate.Kaplan-Meier method showed that the all-cause death rate was similar between two groups,and CVD death rate increased significantly in low sKL patients (P=0.036).Cox regression indicated that lower sKL level was associated with high CVD death rate [OR=0.352,95%CI(0.127-0.977),P=0.045].After adjustment for the general condition,biochemical indicators,the relationship still existed [OR=0.331,95% CI (0.117-0.933),P=0.037].In no or mild vascular calcification patients (AAC ≤4),compared with high sKL patients,low sKL patients had no significant difference rate in all-cause mortality.The CVD mortality was significantly higher in high sKL (P=0.035) compared with low sKL.In severe calcification group (AAC > 4),all-cause death and CVD death rates were similar between different sKL groups (P=0.991 and 0.522,respectively).Conclusions Lower sKL has the high CVD death rate and sKL level decreasing is an independent risk factor for CVD death in MHD patients.The lower sKL concentration in MHD patients with no or mild calcification may predict CVD mortality.This study suggests that sKL levels may be helpful in predicting the outcome of patients with MHD.

ABSTRACT

Objective To investigate the relationship between serum phosphorus variability and mortality in maintenance hemodialysis (MHD) patients. Methods A total of 502 MHD cases from Renji hospital hemodialysis center were registered in Shanghai Registry Network from January 2007 to April 2015. They were recruited with general information, laboratory results and outcomes. According to their median of coefficient of variation (CV) of blood phosphorus, the patients were divided into high variation group (CV≥0.226 mmol/L) and low variation group (CV60 years of age (HR=2.762, 95%CI 1.707?4.468, P60 years of age (HR=2.666, 95%CI 1.469?4.837, P=0.001), low hemoglobin (HR=0.480, 95%CI 0.238?0.801, P=0.005), and high CV of phosphorus (HR=1.655, 95%CI 1.003?2.729, P=0.049) were independent risk factors for cardiovascular disease mortality. There was no significant statistical difference between patients phosphorus on target and patients phosphorus below target in all?cause disease mortality (P=0.065) and cardiovascular disease mortality (P=0.425). High variation group whose phosphorus on target had higher all?cause mortality and cardiovascular disease mortality than those in low variation group (29.2% vs 16.9%, P=0.047; 15.0% vs 6.0%, P=0.033). Kaplan?Meier method showed that patients with high phosphorus variation had higher all?cause (P=0.023) and cardiovascular disease mortality (P=0.047) than patients with low phosphorus variation. Conclusions The high CV of phosphorus is independently correlated with all?cause and cardiovascular disease mortality. Patients with standard ? reaching phosphorus in the low variation group have a lower mortality. A serum phosphorus level sustainably reaching the standard may improve the survival in MHD patients.
