Objective: To examine the causal relationship between body mass index (BMI) and 25 types of autoimmune diseases (ADs) using Mendelian randomization (MR) study method. Methods: The genome-wide association study (GWAS) data for BMI and 25 types of ADs were obtained from IEU OPEN GWAS database. Single nucleotide polymorphisms (SNPs) related to BMI were used as instrumental variables, 25 types of ADs were used as study outcomes, and MR analysis was performed using inverse variance weighted (IVW) method. Heterogeneity was evaluated using Cochran's Q test, horizontal pleiotropy was tested using MR-Egger regression and MR-PRESSO, and results robustness was verified with leave-one-out method. Results: Cochran's Q test showed heterogeneity of MR analysis results (P<0.05), and a random effect model was employed. The results of MR analysis showed that elevated BMI increased the incidence risks of type 1 diabetes mellitus (OR=1.519, 95%CI: 1.281-1.801), IgA nephropathy (OR=1.227, 95%CI: 1.134-1.327), adult Still disease (OR=1.002, 95%CI: 1.001-1.003), multiple sclerosis (OR=1.303, 95%CI: 1.115-1.523), narcolepsy (OR=1.029, 95%CI: 1.017-1.040), Hashimoto thyroiditis (OR=1.561, 95%CI: 1.391-1.751), autoimmune hepatitis (OR=1.481, 95%CI: 1.076-2.038), rheumatoid arthritis (OR=1.209, 95%CI: 1.054-1.386), psoriasis vulgaris (OR=1.719, 95%CI: 1.427-2.070) and pernicious anemia (OR=1.001, 95%CI: 1.000-1.002). No causal relationship was found with other ADs (all P>0.05). MR-Egger regression identified no horizontal pleiotropy of instrumental variables (all P>0.05), while MR-PRESSO test identified partial horizontal pleiotropy (all P<0.05), which remained consistent with the original results after adjustment (P>0.05). Leave-one-out analysis showed results robustness. Conclusion There are causal relationship among BMI and type 1 diabetes mellitus, IgA nephropathy, adult Still disease, multiple sclerosis, narcolepsy, Hashimoto thyroiditis, autoimmune hepatitis, rheumatoid arthritis, psoriasis vulgaris and pernicious anemia.

Objective:To design a new jaw-lifting auxiliary tool and explore its effect in painless bronchoscopy.Methods:From January to December 2023, convenience sampling was used to select 160 patients who underwent painless bronchoscopy at the Endoscopy Center of the First Hospital of Jiaxing as subjects. The subjects were divided into an experimental group ( n=80) and a control group ( n=80) using a random number table method. During painless bronchoscopy, the experimental group used a new jaw-lifting auxiliary tool to open the airway, while the control group used traditional manual methods to open the airway. Two groups were compared patient oxygen saturation at different time points, and bronchoscopy passage time through the glottis. Results:The number of cases in which blood oxygen saturation <95% occurred at different time points in the experimental group was lower than that in the control group (all P<0.05). The time for bronchoscopy to pass through the glottis in the experimental group was shorter than that in the control group, and the difference was statistically significant [ (2.86±0.69) s vs. (3.20±0.96) s, P<0.05] . Conclusions:Using a new jaw-lifting auxiliary tool during painless bronchoscopy can reduce the decreased oxygen saturation in patients and shorten the time for bronchoscopy to pass through the glottis. It can be further promoted and applied in clinical practice.

Objective: To investigate the relationship between the EBV-induced liver injury and caspase-3/6 in children. Methods: Data of 249 patients seen from July 2016 to June 2017 who got infection with EBV were collected in second affiliated hospital of Wenzhou Medical University and the patients were divided into two groups; 168 patients who were diagnosed with hepatitis were selected for abnormal liver function group, laboratory tests were performed in acute phase and convalescent phase. Meanwhile the 81 patients, whose liver function were normal were selected for normal liver function group. Two ml of blood plasma was collected from each patient from both groups at the beginning and after a week’s treatment of the abnormal liver function group. The patients were aged from 1 to 14 years. The abnormal liver function group was further divided into four groups: young children (1-3 years old), preschool children (4-6 years old), school children (7-10 years old), teenagers (10-14 years old). Firstly, we recorded their alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), gamma glutamyl transpeptidase (GGT) and direct bilirubin (DBIL), then by the use of enzyme linked immunosorbent assay (ELISA) we measured the protein level of caspase-3 and caspase-6. Results: In the group of abnormal liver function group, in the acute phase of the teenagers the level of ALT, caspase-3 and caspase-6 are improved significantly(927.2±82.5 vs. 158.5±41.4, P<0.001, 169.8±52.8 vs. 91.5±10.1, P<0.001, P<0.05, 82.2± 2.6, P<0.001, 965.8±31.5, P<0.001, 184.8±14.3, P<0.001), while the AST, TBLL, GGT and DBLL had no significant difference. Conclusions In the process of EBV-induced liver injury, there was a linear correlation between the increase of caspase-3/6 and ALT in the acute stage, suggesting that EBV-induced liver injury is closely related to caspase-3/6.

Objective To investigate the relationship between the incipient serum C-reactive protein (CRP) and clinicopathologic features in anti-neutrophil cytoplasmic antibody associated vasculitis (AAV).Methods Data of 138 consecutive AAV patients were collected.According to their serum CRP levels,patients were divided into group 1 with normal CRP,group 2 with slightly increased CRP and group 3 with severely increased CRP.Clinical features of AAV and histopathologic features of the kidney injury were compared among groups.Results CRP levels increased in 77.53％ AAV patients on admission.Patients in the group of severely increased CRP had the highest levels of BVAS,serum C3,serum ANCA titer,leukocyte counts and the lowest levels of hemoglobin and albumin among the 3 groups (all P ＜ 0.05).The mortality during the stage of therapy was highest in patients with severely increased CRP (P ＜ 0.05).The focal kidney damage was more obvious in patients with severely increased CRP.There was no significant difference in renal prognosis among patients with different CRP levels.Conclusion The levels of incipient serum C-reactive protein of AAV vary in different patients and are positively correlated with patients' inflammation status as well as the disease activity,but are not correlated with the severity of kidney injury.

Objective To evaluate the effect of 6% hydroxyethyl starch 130∕0. 4 on acute kidney injury in elderly patients in a prospective, multicenter, randomized, double?blind, controlled clinical tri?al. Methods A total of 120 patients of both sexes, aged 65-82 yr, weighing 56-83 kg, of American So?ciety of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective orthopaedics and hernia surgery, were divided into either hydroxyethyl starch group ( group HES) or lactated Ringer′s solution group ( group LR) , with 60 patients in each group. Hydroxyethyl starch and lactated Ringer′s solution were infused intra?venously at a rate of 7. 5 ml∕kg during 1st hour of surgery in HES and LR groups, respectively. Lactated Ringer′s solution was then infused at a rate of 5 ml∕kg starting from 2nd hour of surgery until the end of sur?gery in both groups. Before surgery, at the end of surgery and at 1, 3 and 5 days after surgery, blood sam?ples and urine specimens were collected for determination of the concentrations of neutrophil gelatinase?asso?ciated lipocalin, interleukin?18 (IL?18), plasma creatinine, urine β2 microglobulin and urine albumin.
The estimated glomerular filtration rate was calculated. Results The level of urine IL?18 was significantly higher at each time point after surgery than before surgery and immediately after the end of surgery ( P<0.05) . There were no significant differences between the two groups in the levels of urine IL?18, plasma creatinine, plasma and urine neutrophil gelatinase?associated lipocalin, plasma IL?18, urineβ2 microglob?ulin and urine albumin and estimated glomerular filtration rate at each time point ( P>0.05) . Conclusion Compared with lactated Ringer′s solution, 6% hydroxyethyl starch 130∕0.4 does not aggravate acute kidney injury in elderly patients.
