Objective:To investigate the characteristics of computed tomography(CT) and magnetic resonance imaging(MRI)of focal peliosis hepatis (PH).Methods:From January 1, 2015 to December 31, 2022, a total of 8 PH patients (10 lesions) diagnosed pathologically in Yueqing People′s Hospital were collected. The location, size, and shape of the lesions, as well as the CT (4 patients with 4 lesions) and MRI (5 patients with 7 lesions) characteristics of the patients were analyzed. Descriptive method was used for statistical analysis.Results:Among the 8 PH patients, 6 patients had lesions located in the right lobe of the liver, 1 in the left lobe of the liver, and 1 (3 lesions) in both left and right lobes of the liver. Eight lesions were round or round-like, and 2 lesions were irregularly shaped. The median maximum diameter of the lesions was 4.2 cm (ranged from 2.2 to 9.3 cm), of which the maximum diameters of 2 lesions were less than 3.0 cm, those of 6 lesions were 3.1 to 5.0 cm, and those of 2 lesions were more than 6.0 cm. Nine lesions had clear boundaries, and 1 lesion had blurred boundary; 9 lesions had capsule, 1 lesion had no capsule; 1 lesion had blood vessels passing through it. The CT plain scan of 4 patients (4 lesions) showed that 3 lesions had uniform density and 3 lesions had low density, the CT enhancement showed that 2 lesions were significantly enhanced in the arterial phase, 3 lesions were sustained moderately enhanced in the portal phase, and 2 lesions were sustained mildly enhanced in the delayed phase. The MRI plain scan of 5 patients (7 lesions) showed uniform signals in 6 lesions, low signal in 3 lesions and equal signal in 4 lesions on T1-weighted images, high signal in 6 lesions on T2-weighted images, high signal in 3 lesions and equal signal in 4 lesions on diffusion-weighted images. The MRI enhancement showed that 4 lesions were significantly enhanced in the arterial phase, 5 lesions were sustained moderately enhanced in the portal phase, and 6 lesions showed sustained mild enhanced in the delayed phase.Conclusion:The PH lesions are round or round-like, with clear or unclear boundaries and uniform or uneven density, and are characterised by low density on CT and MRI plain scan, low signal on T1-weighted images, and high signal on T2-weighted images and diffusion-weighted images, and moderate or significant sustained enhancement on CT and MRI enhancement.

Objective:To analyze the effect of the over-the-scope-clip system (OTSC) system in the treatment of iatrogenic gastrointestinal perforation.Methods:Retrospective selection of clinical data from 21 patients with gastrointestinal perforation during endoscopic examination and treatment from May 2016 to December 2023 in the Department of Gastroenterology, Beijing Friendship Hospital, Capital Medical University. By analyzing the patient's basic information, perforation cause, perforation diameter, length of hospital stay, post-treatment outcome, complications, and treatment success rate, the effectiveness of using the OTSC system to treat iatrogenic gastrointestinal perforation is comprehensively evaluated, and the influencing factors that may be related to the failure of OTSC system closure are analyzed. Independent sample t-test is used for inter group comparison of metric data that conforms to normal distribution. Fisher's exact probability test was used for inter group comparison of count data.Results:There were 21 cases of acute iatrogenic gastrointestinal perforation, including 12 males and 9 females, aged (61.95±15.47) years, 4 cases of duodenal perforation, 10 cases of gastric perforation, and 7 cases of colon perforation. The diameter of the perforation was (1.18±0.56)cm, and the perforation sealing time was (8.29±4.42) min. Among the 21 patients, 5 cases of occlusion failed, of which 2 cases of sigmoid colon perforation were transferred to surgery in time due to OTSC insufficiency, 3 cases were perforated in duodenal colon and colonic splenic area, 3 cases of delayed abdominal infection after OTSC system occlusion, 16 cases of OTSC system closure and perforation without complications such as delayed perforation, and the average length of hospital stay of patients in the OTSC system wound closure group was (11.56±6.53) d, which was shorter than that in the OTSC system closure failure group ((38.00±21.34) d), The proportion of passive perforation in the failure group (100%, 5/5) > the success group (31%, 5/16).The occlusion success rate of passive perforation in the OTSC system (50%, 5/10) < active perforation (100%, 11/11), the diameter of perforation of the failure group ((1.72±0.80)cm) was significantly > that of the successful group ((1.06±0.49)cm), the diameter of perforation ≥2.0 cm in the failure group (80.0%, 4/5) was significantly > that of the successful group (12.5%, 2/16), the proportion of duodeno-colonic perforation in the failure group (100.0%, 5/5) > the success group (37.5%, 6/16), the difference was statistically significant ( P values were 0.049, 0.012, 0.012, 0.037, 0.011, and 0.035, respectively). Conclusion:The closure of acute iatrogenic gastrointestinal perforation by the OTSC system has significant therapeutic effects and can reduce the probability of surgical conversion due to perforation to a certain extent. It is worth promoting and applying. The diameter of the perforation (≥2 cm), the perforation method (passive perforation), and the perforation site (the difficult part of duodenum-colon operation) may be the relevant influencing factors for the failure of the occlusion of the OTSC system.

OBJECTIVE: This study aimed to explore the association between humidity exposure and the risk of cardiovascular disease (CVD), utilizing follow-up data and relative humidity (RH) metric assessments. METHODS: We extracted the baseline data from the China Hypertension Survey (CHS) of 24,510 enrolled participants aged ≥ 35 years without a history of CVD between 2012 and 2015 and followed them up from 2018 to 2019. The National Meteorological Information Center (NMIC) of the China Meteorological Administration (CMA) provided the quality-controlled relative humidity (RH) datasets. Cox proportional hazards models were used to estimate hazard ratios ( HRs) for CVD in relation to RH. RESULTS: During the follow-up period (2018-2019), 973 patients with CVD were identified. The HR of CVD risk was 1.17 (95% CI: 1.04-1.31) per 10% increase in summer mean RH. Compared with participants in the 3 ^rd quintile group, those in the 1 ^st and 5 ^th quintiles of RH had a higher risk of CVD. For summer mean RH, the HRs (95% CIs) for the 1 ^st and 5 ^th quintiles were 1.34 (1.04-1.71) and 1.44 (1.14-1.83), respectively. The relationship ("U" shape) between summer mean RH and the risk of CVD was nonlinear. Stratified analyses indicated that the risk of CVD was substantially influenced by the summer mean RH in female, older individuals, and those in southern China. CONCLUSION Unsuitable (too high or low) humidity environments affect the risk of CVD. Our study highlights those future policies for adapting to climate change should consider the humidity-CVD relationship.

Objective:To analyze the relationship and clinical value between serum matrix metalloproteinases-3 (MMP-3) and rheumatoid arthritis (RA).Methods:By using retrospective study to collect 123 patients with RA diagnosed in our hospital from January 2019 to January 2020 as the RA group. Among the patients, there are 25 males and 98 females, the median age is 60 years old. During the same term, 53 healthy people were selected as the control group, with 12 males and 41 females, the median age is 55 years old. MMP-3, erythrocyte sedimentation rate (ESR), high sensitivity C-reactive protein (hs-CRP), rheumatoid facotrs (RF), anti-cyclocitrulline factor (ACCP) in peripheral blood of all subjects were detected. Disease activity score of 28 joints (DAS28) were collected. This research used T test, Spearman correlation analysis and receiver operating characteristic curve (ROC curve) to analyze the relationship between MMP-3 and other clinical biochemical indices, and the efficacy of MMP-3 in the diagnosis of RA.Results:Compared with the control group (26.30±14.83)ng/ml, the levels of serum MMP-3 in the RA group (79.71±123.54) ng/ml had significantly increased ( t=-4.95, P<0.001). The serum concentration of MMP-3 in RA patients was significantly correlated with ESR, hs-CRP and DAS28 ( r value were 0.521, 0.372, 0.405 respectively, P<0.001). The area under the curve (AUC) of MMP-3 to diagnose RA was 0.765, and the sensitivity was 64.44%, and the specificity was 75.76%, cut-off of MMP-3 were 32.50 ng/ml. Conclusions:The levels of serum MMP-3 in the RA group had significantly increased. MMP-3 and the disease activity were highly correlated. MMP-3 can be used as an indicator of RA disease activity, also can significantly improve the diagnostic efficacy, treatment and warning of early RA.
