Objective To improve the clinical prognosis of patients by reviewing ten years epidemiology data of acute poisoning inpatients.Methods The epidemiology data of the acute poisoning inpatients from 2006-2015 were retrospectively analyzed.The indexes including age,gender,nationality,geographical distribution,substance of poison,seasons,diagnosis and fee-for-service were collected.Results There were 1 083 patients with acute poisoning in total,624 cases (57.6％) for gas poisoning,213 cases (19.7％) for pesticide poisoning,136 cases (12.6％) for drug poisoning,74 cases (6.8％) for food poisoning and 36 cases for others.The ration of male to female was 0.94:1.The age of 31 to 45 range accounted for the highest proportion.The incidence of poisoning in 2011-2015 was significantly higher than that in 2006-2010 (P ＜0.05).The geographical distribution was also significantly different (P ＜0.05),most of the cases were in Shihezi city,then were Manasi and Sawan counties.Among the 1 083 patients,59％ cases were cured,33.6％ cases were improved after treatment,and the mortality rate was 2.6％.Feefor-service was also significantly increased in the older patients or males,and substance of poisoning dependent.The highest treatment cost was carbon monoxide poisoning,then were pesticide,drugs and food.Conclusions The common causes of poisoning in Shihezi city were carbon monoxide,organophosphorus pesticide,botulism and drugs,more emergency medical service should prevent poisoning and treat these patients.

Hepatitis E is a globally distributed infection that varies in seroprevalence between developed and developing regions.In the less developed regions of Asia and Africa,a high seropositivity rate has been reported for hepatitis E virus(HEV)antibodies.Although acute hepatitis E is often self-limited and has a favorable prognosis,some populations experience severe manifestations,which may progress to liver failure.Moreover,some immunocompromised patients are at risk of developing chronic HEV infection and cirrhosis.Proactive screening,reducing misdiagnosis,improving patient management,timely anti-viral therapy for severe and chronic cases,and vaccination of high-risk groups are important measures to reduce the morbidity of hepatitis E.This review focused on the clinical presentation,management,and prevention of hepatitis E.

OBJECTIVETo investigate the inhibitory effect and underlying mechanism of total saponins from Paris polyphylla var. yunnanensis on the proliferation of salivary adenoid cystic carcinoma ACC-83 cells.

METHODSIn vitro cell culture was performed. The proliferation of ACC-83 cells treated with different concentrations (5, 10, 20, 40, 60, 80, 100 μg·mL⁻¹) of total saponins from Paris polyphylla var. yunnanensis was observed using CCK-8 assay. Meanwhile, the apoptosis of ACC-83 cells treated with different concentrations (25, 50, 100 μg·mL⁻¹) of the total saponins was observed using flow cytometry. The expression levels of macrophage migration inhibitory factor (MIF) and CD74 were measured using Western blot and reverse transcription-polymerase chain reaction.

RESULTSThe total saponins from Paris polyphylla var. yunnanensis induced apoptosis and expressed dose-effect relationship. ACC-83 cells expressed MIF and CD74, and the total saponins suppressed MIF and CD74 expression in ACC-83 cells.

CONCLUSIONSThe total saponins from Paris polyphylla var. yunnanensis can significantly inhibit the proliferation, suppress MIF and CD74 expression, and promote apoptosis in ACC-83 cells. This study provides a theoretical basis for the treatment of salivary adenoid cystic carcinoma using Paris polyphylla var. yunnanensis.

This study examined the incidence, neuropsychological characteristics and risk factors of cognitive impairment 3 months after stroke in China. Five regions that differed in geography and economy in China were selected. Patients from the hospitals located in the five regions were prescreened at admission, and the demographic data, vascular risk factors and clinical characteristics of stroke were obtained. A battery of cognitive-specific domain tests was performed in the patients who failed to pass cognitive screening 3 months post stroke. Patients were diagnosed as having post-stroke cognitive impairment (PSCI) or no cognitive impairment (NCI) based on the results of the neuropsychological tests. Univariate analysis was performed for suspect risk factors, and significant variables were entered in multivariable logistic regression analysis. Our results showed that a total of 633 patients were recruited 3 months after stroke; complete cognitive tests were performed in 577 of the stroke patients. The incidence of PSCI in these Chinese patients was 30.7%. There were 129 (22.4%) patients with visuospatial impairment, 67 (11.6%) with executive impairment, 60 (10.4%) with memory impairment and 18 (3.1%) with attention impairment. The risk factors associated with PSCI were older age (odds ratio [OR] 1.76, 95% confidence interval [CI] 1.20-2.58), low education level (OR 2.45, 95% CI 1.65-3.64), depressive symptom (OR 1.69, 95% CI 1.09-2.61), obesity (OR 2.57, 95% CI 1.41-4.71), stroke severity 3 months post stroke (OR 1.62, 95%CI 1.10-2.37) and cortex lesion (OR 1.55, 95% CI 1.04-2.31). It was concluded that PSCI occurs commonly 3 months after first-ever stroke in Chinese patients. Visuospatial ability may be the most frequently impaired cognitive domain for the patients with stroke. The critical risk factors of PSCI are older age, low education level, depressive symptom, obesity, stroke severity 3 months post stroke and cortex lesion.

Background and aim:Few studies have reported hepatitis B surface antigen(HBsAg)kinetics after nucleos(t)ide analog(NA)discontinuation in patients with noncirrhotic chronic hepatitis B(CHB).The study specifically investigated long-term HBsAg kinetics after NA discontinuation. Methods:Between January 2014 to January 2024,this study prospectively enrolled 106 outpatients with noncirrhotic CHB who met the discontinuation criteria after NA consolidation treatment.Demographic,clinical,and laboratory data were collected and analyzed after NA discontinuation. Results:Ninety-six patients who finished 5 years of follow-up were included.HBsAg remained unde-tectable in 29 patients with end of treatment(EOT)HBsAg negativity.Among 67 patients with EOT HBsAg positivity,HBsAg seroclearance occurred in 12(17.9％)patients with an estimated annual inci-dence of HBsAg seroclearance of 3.6％.Patients with EOT HBsAg levels of ≤1000 IU/mL had a higher HBsAg seroclearance rate than those with EOT HBsAg levels of＞1000 IU/mL(33.3％vs.5.4％).The pro-portion of patients with HBsAg ≤1000 IU/mL increased during follow-up.Logistic regression analysis indicated that the EOT HBsAg level was an independent factor for HBsAg seroclearance and an HBsAg level decline exceeding 1 log10 IU/mL.The optimal EOT HBsAg cutoff for both HBsAg seroclearance and an HBsAg level decline exceeding 1 log10 IU/mL was 359 IU/mL. Conclusions:Patients with EOT HBsAg negativity experienced no relapse and maintained HBsAg sero-clearance during 5 years of follow-up after NA discontinuation.A higher HBsAg seroclearance rate can be obtained in patients with EOT HBsAg levels of ≤1000 IU/mL during 5 years of follow-up after NA discontinuation.Close monitoring and proper NA retreatment are recommended to guarantee the safety of NA discontinuation.

OBJECTIVE: To investigate the role of cyclophilin A in the foaming process of macrophages induced by free silica( SiO_2). METHODS: The human peripheral blood mononuclear cell THP-1 in the logarithmic growth phase was induced and differentiated into human macrophages with phorbol 12-myristate 13-acetate at 100 μg/L for 48 hours. The cells were divided into 4 groups. The cells in the blank control group were not treated. The cells in the oxidized low-density lipoprotein( ox-LDL) control group were treated with a final concentration of 50 mg/L ox-LDL. The cells of 50 mg/L SiO_2 group were treated with 50 mg/L of SiO_2 and ox-LDL. The cells of 100 mg/L SiO_2 group were treated with 100 mg/L of SiO_2 and 50 mg/L of ox-LDL. After treatment of cells for 48 h,cell viability was measured by MTS method. The lipid accumulation of cells was observed by oil red O staining and colorimetric method; the expression of cyclophilin A in cell supernatant was detected by enzyme-linked immunosorbent assay,and the expression of cyclophilin A in the cells was detected by Western blotting. RESULTS: The cell viability was the highest when the concentration of SiO_2 was 100 mg/L compared with the control and other four SiO_2groups( P < 0. 01). The cell foaming change in the 100 mg/L SiO_2 group observed by oil red O staining significantly increased compared with the blank control group. The expression of total cholesterol,free cholesterol increased in the ox-LDL control group,50 mg/L SiO_2 group and 100 mg/L SiO_2group( P <0. 05),and the cholesterol specific gravity increased( P < 0. 05) compared with the blank control group,meanwhile the expression of cyclophilin A in the cell supernatant increased( P < 0. 05),and the expression in the macrophages cells decreased( P < 0. 05). CONCLUSION: Cyclophilin A is involved in the foaming process of macrophages induced by SiO_2.

Objective:To investigate the morphological characteristics of coracoid process in different stages of temporomandibular joint osteoarthrosis (TMJOA), and to provide theoretical data for clinical and anatomic study.Methods:A total of 290 patients who were diagnosed with TMJOA in the Department of Temporomandibular Joint, Kunming Medical University School and Hospital of Stomatology from January 2015 to February 2021 were collected, including 69 males and 221 females, with age of (35.1±13.7) years (16-69 years old), 64 cases of unilateral lesions (64 sides), and 226 cases of bilateral lesions (452 sides). According to the TMJOA X-ray staging standard put forward by Ma Xuchen in 2005, the affected joints were divided into stage Ⅰ (227 sides), stage Ⅱ (38 sides), stage Ⅲ (164 sides) and stage Ⅳ (87 sides). Twenty-six patients without clinical and imaging manifestations of temporomandibular disorders in the Department of Radiology, Kunming Medical University School and Hospital of Stomatology from October 2020 to June 2021 were selected as the control group, including 8 males and 18 females. The age was (34.3±13.9) years (17-60 years). The dicom data of each group were imported into Simplant Pro 11.04 software to measure the height of coracoid process, anteversion angle and the ratio of coracoid vertex to mandibular corner to condylar vertex to mandibular angle. R 3.6.1 was used to analyze the difference of the morphological characteristics of coracoid process between in the affected side of TMJOA and in the both sides of the control group, in the healthy side and the affected side of unilateral patients and in different stages of TMJOA.Results:The height of the coracoid process [(16.26±2.81) mm], the ratio of the coracoid process vertex-mandibular angle point and the condyle vertex-mandibular angle point distance [0.96(0.92,1.01)] on the affected side of TMJOA were significantly higher than those in the control group [(15.31±3.03) mm; 0.95(0.89, 0.99)] ( t=2.18, P=0.033; Z=2.87, P=0.004). There was no significant difference between the ante-version angle and the control group ( t=-1.37, P=0.176). The ratio of the distance between the apex of the coracoid process and the apex of the mandibular angle to the apex of the condyle and the angle of the mandible in the affected side of unilateral patients was significantly greater than that in the healthy side ( t=-3.46, P=0.001). There was no significant difference in coracoid height, coracoid anteversion angle and the healthy side ( t=-1.85, P=0.069; t=-0.06, P=0.955) in different periods. The intra-group analysis showed that there was no significant difference in the height of the coracoid process in different stages ( F=0.37, P=0.774). There was no significant difference in the ante-version angle of the coracoid process: stage Ⅰ, stage Ⅱ, and stage Ⅲ ( P>0.008), but all were significantly smaller than stage Ⅳ ( PⅠ-Ⅳ<0.001, PⅡ-Ⅳ=0.009, PⅢ-Ⅳ<0.001). The ratio of the distance between coracoid apex-mandibular angle and condyle apex-mandibular angle: there was no significant difference in stage Ⅰ, stage Ⅱ, and stage Ⅲ ( P>0.008), and stage Ⅰ and stage Ⅲ were significantly smaller than stage Ⅳ ( P<0.001). Conclusions:The coracoid height and the ratio of the coracoid apex-mandibular angle to the condyle apex-mandibular angle distance on the TMJOA side were significantly greater than those without temporomandibular joint disorders. The bone deposition was mainly concentrated in the upper and posterior part of the condyle. TMJOA had a certain correlation with the height of the coracoid process.

Background: and Purpose The rate of donepezil discontinuation and the underlying reasons for discontinuation in Asian patients with Alzheimer’s disease (AD) are currently unknown. We aimed to determine the treatment discontinuation rates in AD patients who had newly been prescribed donepezil in routine clinical practice in Asia. Methods: This 1-year observational study involved 38 institutions in seven Asian countries, and it evaluated 398 participants aged 50–90 years with a diagnosis of probable AD and on newly prescribed donepezil monotherapy. The primary endpoint was the rate of donepezil discontinuation over 1 year. Secondary endpoints included the reason for discontinuation,treatment duration, changes in cognitive function over the 1-year study period, and compliance as assessed using a clinician rating scale (CRS) and visual analog scale (VAS). Results: Donepezil was discontinued in 83 (20.9%) patients, most commonly due to an adverse event (43.4%). The mean treatment duration was 103.67 days in patients who discontinued. Among patients whose cognitive function was assessed at baseline and 1 year, there were no significant changes in scores on the Mini-Mental State Examination, Montreal Cognitive Assessment, and Trail-Making Test–Black and White scores, whereas the Clinical Dementia Rating score increased significantly (p<0.001). Treatment compliance at 1 year was 96.8% (306/316) on the CRS and 92.6±14.1% (mean±standard deviation) on the VAS. Conclusions In patients on newly prescribed donepezil, the primary reason for discontinuation was an adverse event. Cognitive assessments revealed no significant worsening at 1 year, indicating that continuous donepezil treatment contributes to the maintenance of cognitive function.
