ABSTRACT

Objective:To determine whether insulin resistance is associated with all-cause mortality in subjects without diabetes.Methods:A total of 505 participants without diabetes, 198 with normal glucose tolerance (NGT) and 307 with impaired glucose tolerance (IGT), were recruited from the Daqing Diabetes Study. The participants were followed up for 30 years. They were stratified into three groups (tertiles) according to baseline homeostasis model assessment of insulin resistance(HOMA-IR) levels, as the HOMA-IR 0, the HOMA-IR 1 and the HOMA-IR 2 groups, to assess the predictive effect of insulin resistance on risk of all-cause mortality.Results:During the 30-year follow-up, 52, 56 and 78 participants died across the three HOMA-IR groups, respectively. The corresponding mortality per 1 000 person-years (95 %CI) were 12.12 (9.56-15.01), 13.10 (10.46-16.03) and 19.91 (16.73-23.15), respectively. Participants in the HOMA-IR 2 group had a significantly higher risk of death than those in the HOMA-IR 0 group after adjustment of age, sex and smoking status ( HR=1.97,95 %CI 1.38-2.81, P<0.001). Cox analyses showed that a one standard deviation increase in HOMA-IR was associated with a 22% increase in the mortality after adjustment of potential confounders ( HR=1.22, 95 %CI 1.08-1.39, P=0.002). Conclusions:Insulin resistance is associated with increased risk of all-cause death in Chinese people without diabetes, suggesting that improving insulin resistance could be beneficial for people without diabetic in reducing risk of long-term all-cause mortality.

ABSTRACT

A lung diffusion function detection system is designed. Firstly, the controllable collection of air, test gas source and calibration gas source was based on single-breath method measurement principle. Secondly, pulmonary diffusing capacity for carbon monoxide (DlCO) was calculated by gas concentration measured by the non-dispersive infrared sensor to measure, the gas flow measured by the differential pressure sensor, and the temperature, humidity and atmospheric pressure sensors to test and evaluate the quantitative detection and evaluation of lung diffusion function. Moreover, a preliminary verification of the lung diffusion function detection system was implemented, and the results showed that the error of the lung carbon monoxide diffusion and the alveolar volume did not exceed 5%. Therefore, the system has high accuracy and is of great value for early screening and accurate assessment of COPD.

ABSTRACT

Indirect energy metabolism measurement is the gold standard for providing nutritional support for critical illness. The accuracy of the measurement data directly affects the outcome of the disease. In order to study the influence of sampling delay on the accuracy of energy metabolism measurement under mechanical ventilation, the Matlab/Simulink platform and respiratory electrical model were used for simulation and quantitative analysis. The results show that the error of indirect energy metabolism measurement increases with the increase of sampling delay, the error of sampling delay in mechanical ventilation mode is larger than that of spontaneous breathing, and the error of sampling delay in PCV mode of mechanical ventilation is larger than that in VCV mode. Therefore, there should be different sampling delay compensation strategies under severe mechanical ventilation and its different control modes.

ABSTRACT

Objective:To investigate the cleaning status of silicone oil attached ophthalmic surgical instruments in China, so as to provide reference and suggestions for the standard cleaning process of silicone oil attached ophthalmic surgical instruments.Methods:61 hospitals in 22 provinces (regions, municipality) in China were selected as the objects of investigation. The on-site treatment, pretreatment and routine cleaning of silicone oil attached ophthalmic surgical instruments were investigated by questionnaire from November 2019 to January 2020.Results:18.033% (11/61) hospitals had mixed silicone oil attached ophthalmic surgical instruments and other instruments intraoperatively, 11.475% (7/61) hospitals didn′t wipe silicone oil and other visible contaminants postoperatively. 18.033% (11/61) hospitals didn′t carry out pretreatment and 4.000% (2/50) hospitals used saline as pretreatment solution; 54.098% (33/61) hospitals were involved in ultrasonic cleaning. 32.787% (20/61) hospitals had water temperature 31-37 ℃ and 4.918% (3/61) hospitals had water temperature>37 ℃during the cleaning process; During pretreatment and routine cleaning, 38.000% (19/50) hospitals and 54.902% (28/51) hospitals selected enzymatic detergent respectively, the contact time between instruments and detergent in specialized hospital was more standardized than that in general hospital ( P<0.001); In flushing, rinsing and final rinsing, there were 29.412% (15/51) hospitals, 11.765% (6/51) hospitals and 3.922% (2/51) hospitals used water that didn′t meet the requirements. 17.647% (9/51) hospitals, 13.725% (7/51) hospitals and 13.725% (7/51) hospitals didn′t record the time of flushing, rinsing and final rinsing. Conclusions:There are still some problems in the cleaning of silicone oil attached ophthalmic surgical instruments in specialized and general hospitals, such as no on-site treatment and pretreatment, improper control of cleaning parameters, and difficulty in ensuring water quality and water time. It is necessary to formulate the cleaning process specification of silicone oil attached ophthalmic surgical instruments as soon as possible to ensure the cleaning quality and avoid the occurrence of postoperative eye complications.

ABSTRACT

Objective:To explore the correlation between the expression levels of serum estradiol and otolin-1 and the recurrence of postmenopausal benign paroxysmal positional vertigo (BPPV).Methods:A total of 116 postmenopausal female patients who were diagnosed with primary BPPV in the Vertigo Treatment Center of Beijing Geriatric Hospital from January 2018 to December 2019 were selected as the research objects. They were divided into recurrence group (27 cases) and the non-recurrence group (89 cases) according to the recurrence during follow-up. The basic data, laboratory indexes and complications of the two groups were compared. The serum estradiol level was detected by electrochemiluminescence and the serum otolin-1 level was detected by enzyme-linked immunosorbent assay. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of serum estradiol and otolin-1 in the recurrence of postmenopausal BPPV patients; Multivariate logistic regression was used to analyze the risk factors of recurrence in postmenopausal BPPV patients.Results:The proportion of severe cough in the recurrence group was higher than that in the non-recurrence group ( P<0.05); the level of estradiol in the recurrence group was significantly lower than that in the non-recurrence group ( P<0.05), and the level of otolin-1 was significantly higher ( P<0.05); ROC results showed that the areas under the curve (AUCs) of serum estradiol and otolin-1 for predicting the recurrence of postmenopausal BPPV patients were 0.852 (95% CI: 0.774-0.911) and 0.722 (95% CI: 0.631-0.801) respectively, and the cut-off values were 18.09 pg/ml and 361.79 pg/ml respectively; Multivariate logistic regression analysis showed that severe cough, estradiol ≤18.09 pg/ml, and otolin-1 >361.79 pg/ml were independent risk factors for recurrence in postmenopausal BPPV patients ( P<0.05). Conclusions:The serum estradiol level of patients with postmenopausal BPPV recurrence decreases, and the level of otolin-1 increases. The abnormal level is an independent risk factor affecting the recurrence of patients with postmenopausal BPPV.

ABSTRACT

Liver failure is a common critical medical disease, and extensive liver cell necrosis within a short period of time exceeds the regeneration capacity of liver cells and thus results in an extremely high fatality rate. Promotion of effective liver regeneration is the key to antagonizing liver failure. Recent studies have shown that bile acid, farnesoid X receptor (FXR), and intestinal microecology play an important role in liver failure and liver regeneration. This article reviews the association between bile acid, FXR, and intestinal microecology and their role in liver failure and liver regeneration, so as to provide new ideas for the treatment of liver failure in clinical practice.

ABSTRACT

We conducted a randomized, open-label, parallel-controlled, multicenter trial on the use of Shuanghuanglian (SHL), a traditional Chinese patent medicine, in treating cases of COVID-19. A total of 176 patients received SHL by three doses (56 in low dose, 61 in middle dose, and 59 in high dose) in addition to standard care. The control group was composed of 59 patients who received standard therapy alone. Treatment with SHL was not associated with a difference from standard care in the time to disease recovery. Patients with 14-day SHL treatment had significantly higher rate in negative conversion of SARS-CoV-2 in nucleic acid swab tests than the patients from the control group (93.4% vs. 73.9%, P = 0.006). Analysis of chest computed tomography images showed that treatment with high-dose SHL significantly promoted absorption of inflammatory focus of pneumonia, which was evaluated by density reduction of inflammatory focus from baseline, at day 7 (mean difference (95% CI), -46.39 (-86.83 to -5.94) HU; P = 0.025) and day 14 (mean difference (95% CI), -74.21 (-133.35 to -15.08) HU; P = 0.014). No serious adverse events occurred in the SHL groups. This study illustrated that SHL in combination with standard care was safe and partially effective for the treatment of COVID-19.

ABSTRACT

Mutants of proteins are the basis for studying their structure and function, this work aimed to establish an efficient and rapid method for constructing multi-site mutants. When four or more adjacent amino acid residues need to be mutated, firstly, two long and two short primers (long primers Ⅰ/Ⅰ, short primersⅡ/Ⅱ) were designed: the long primers contain mutated sites, and the number of mutant bases is ≤20 bp, the short primers do not contain mutated sites; GC contents of the long and short primers are ≤80%, and the difference of annealing temperature is ≤40 °C. Then two sets of reverse PCR amplifications were performed using primer pairs (Ⅰ/Ⅱand Ⅰ/Ⅱ) and templates, respectively. After amplification, each system can obtain non-methylated linear plasmids which contain mutated sites, and the breakpoints of the two sets of linear plasmids amplified by primers Ⅰ/Ⅱ and Ⅲ/Ⅳ were distributed on both sides of the mutated sites. Followed by digested by DpnⅠ to remove the methylated templates, the recovered PCR products, which were mixed in an equimolar ratio, were performed another round of denaturation and annealing: the two sets of linear plasmids were denatured at 95 °C and then annealed with each other's single-stranded DNA as templates to form open-loop plasmids, and then the transformants containing the mutations will be obtained after transformed the open-loop plasmids into Escherichia coli competent cells. Results showed that, this method can mutate 4 to 11 consecutive amino acid residues (8-20 bp) simultaneously, which will greatly simplify the construction of multi-site mutants, Thereby improve the efficiency of protein structure and function research further.

ABSTRACT

Objective:To investigate the long-term effects of metabolically healthy obesity on the risks of type 2 diabetes, cardiovascular disease events, and its mortality over a 23-year follow-up.Methods:Based on the results of an oral glucose tolerance test, there were 519 participants with normal glucose tolerance and 630 with newly diagnosed type 2 diabetes enrolled in 1986 and then given to assess the long-term clinical outcomes during the 23-year follow-up in Daqing. Metabolically healthy obesity was defined as the overweight and obese individuals with no metabolic abnormalities (diabetes, hypertension, hyperlipidemia). Finally, we identified 682 participants (350 with normal glucose tolerance and 332 with newly diagnosed diabetes). They were divided into five groups: 211 individuals with metabolically healthy normal weight (MHNW group), 58 with metabolically healthy overweight and obesity (MHO group), 81, 109, 223 were metabolically unhealthy overweight and obesity with hypertension (MUHO group), type 2 diabetes (MUDO group), hypertension and diabetes (MUHDO group). Incidences of type 2 diabetes, morbidity and mortality of cardiovascular disease were compared among these groups.Results:Over 23 years, instead of the morbidity and mortality of cardiovascular disease, the incidence of type 2 diabetes in MHO group was two times higher than in MHNW group ( 24.1%, 12.5/1 000 person years vs 10.9%, 5.2/1 000 person years, P=0.01), with an age, sex, and smoking history-adjusted hazard ratio ( HR) of 2.42 (95% CI 1.24-4.74, P=0.01). The morbidity and mortality of cardiovascular disease in the groups of overweight and obesity with metabolically unhealthy were higher than in MHNW group, and increased across the subjects with MUHO, MUDO, MUHDO ( P<0.05). Conclusion:Compared with metabolically healthy normal weight participants, the metabolically healthy obese group was at increased risk of type 2 diabetes but not cardiovascular disease events and its mortality. On the contrary, the overweight and obese groups with metabolic abnormalities had significant higher incidence of type 2 diabetes, morbidity and mortality of cardiovascular diseases.

ABSTRACT

This study was to design a chronic obstructive pulmonary disease (COPD) screening equipment, based on the dual-differential pressure throttling technique. The technique combined a wide range, but low-resolution ratio sensor and a narrow range, but high-resolution ratio one. It can accurately detect the indexes of forced vital capacity (FVC), forced expiratory volume in one second (FEV), one second rate(FEV/FVC (%)), and achieve them in a low-cost way. The new designed machine will be compared with a British machine, named ML-3500. The correlations of FVC and FEV between new machine and ML-3500 were 0.998 and 0.999, respectively. The P values of paired test of these two indexes were over 0.05. Bland-Altman analysis of FVC, FEV and FEV/FVC (%) showed that more than 90% of the scatter points of the three parameters fell within the consistency interval. This machine can be used to accurately screen COPD and its low-cost would be advantage to promote in large population.

ABSTRACT

The authors, based on barcode analysis and tracking technology, designed a complete supply chain management system for ophthalmic consumables, systematically solving the traceability challenge of high-value medical consumables ( mainly implanted medical instruments) . This innovation can sizably reduce the inbound/outbound error rate at level-1 and level 2 warehouses of the hospital, downsizing inventory cost expenditure and upsizing work efficiency. The management of "one item for one code"constitutes a traceable closed loop for such consumables, improving the informationized, standardized and refined management, and reducing the incidence of adverse events for medical devices. Thus the quality management system of eye hospitals can be elevated.

ABSTRACT

Objective To investigate the regular spot check implementation of central sterile supply department(CSSD) at hospitals of all grades across China and analyze its influencing factors to provide the basis for further improvement of regular cleaning quality inspection. Methods Cross-sectional study was conducted form February to July of 2017,and 132 hospitals all over the country were selected to investigate with the questionnaire the current status of CSSD management model, staffing and regular cleaning quality inspection. Results The ratio of the nursing staff and the number of beds was 1.15:100,the ratio of staff and the number of beds was 2. 00:100. 81. 82% (n =108) of the hospitals adopted the centralized management model. The qualification rate for regular spot check execution was 87.12% (n=115). The results of multiple logistic regression showed that the centralized management model was more conducive to the regular spot check than the non-centralized management model (OR=4.71,95% CI:1.05-21.08). Conclusions The centralized management model proves positive for the implementation of regular spot checks;and CSSDs should pay more attention to the regular spot check of the cleaning quality.
