Background: and Purpose The optimal management of patients with acute basilar artery occlusion (BAO) is uncertain. We aimed to evaluate the safety and efficacy of endovascular thrombectomy (EVT) compared to medical management (MM) for acute BAO through a meta-analysis of randomized controlled trials (RCTs). Methods: We performed a systematic review and meta-analysis of RCTs of patients with acute BAO. We analyzed the pooled effect of EVT compared to MM on the primary outcome (modified Rankin Scale [mRS] of 0–3 at 3 months), secondary outcome (mRS 0–2 at 3 months), symptomatic intracranial hemorrhage (sICH), and 3-month mortality rates. For each study, effect sizes were computed as odds ratios (ORs) with random effects and Mantel-Haenszel weighting. Results: Four RCTs met inclusion criteria including 988 patients. There were higher odds of mRS of 0-3 at 90 days in the EVT versus MM group (45.1% vs. 29.1%, OR 1.99, 95% confidence interval [CI] 1.04–3.80; P=0.04). Patients receiving EVT had a higher sICH compared to MM (5.4% vs. 0.8%, OR 7.89, 95% CI 4.10–15.19; P<0.01). Mortality was lower in the EVT group (35.5% vs. 45.1%, OR 0.64, 95% CI 0.42–0.99; P=0.05). In an analysis of two trials with BAO patients and National Institutes of Health Stroke Scale (NIHSS) <10, there was no difference in 90-day outcomes between EVT versus MM. Conclusion In this systematic review and meta-analysis, EVT was associated with favorable outcome and decreased mortality in patients with BAO up to 24 hours from stroke symptoms compared to MM. The treatment effect in BAO patients with NIHSS <10 was less certain. Further studies are of interest to evaluate the efficacy of EVT in basilar occlusion patients with milder symptoms.

Objective To analyze the infection situation of Helicobacter pylori (Hp) and its correlation with pepsinogen (PG) in the 60~80 year old population in Jianye District, Nanjing City. Methods From December 2018 to December 2020, 758 elderly people aged 60 to 80 in the community in Jianye District Nanjing City. were selected. All subjects were tested for Hp by 13C-UBT method, and clinical signs of Hp positive people aged 60 to 80 years were analyzed. Including gender, age, alcohol consumption, family history of stomach cancer, chronic gastritis, and spicy eating habits; Hp positive group was given amoxicillin capsule 1.0g/ time, twice a day, esomeprazole magnesium enteric-coated tablet 20mg/ time, twice a day, clarithromycin tablet 0.5g/ time, twice a day for 8 weeks, and Hp was detected again after the end of treatment. All levels of PGI, PGII and PGI/PGII were determined by ELISA. The serum PG level of the experimental group and the control group and the serum PG level of the Hp positive population before and after Hp eradication were compared, and the correlation between Hp infection and PG level in the elderly population was analyzed by Pearson correlation. Results A total of 161 cases (21.24%) of 758 patients with chronic gastritis had Hp infection. The proportion of Hp infection in males was significantly higher than that in females (χ²=4.128，P<0.05). The proportion of Hp infection in 70-80 years was higher than that in 60-69 years(χ²=6.771, P<0.05). The proportion of Hp infection in drinking elderly was higher than that in non-drinking elderly (χ² =8.305，P<0.05). The proportion of Hp infection in the elderly with family history of gastric cancer was higher than that in the elderly without family history of gastric cancer (χ²=6.169，P<0.05). The proportion of Hp infection in elderly patients with chronic gastritis was higher than that in patients without chronic gastritis (χ²=5.576 , P<0.05). The proportion of Hp infection in the elderly with spicy diet was higher than that in the non-spicy diet group(χ²=7.936, P<0.05). The levels of PGI and PGI/PGII in the experimental group were significantly higher than those in the control group (P<0.05). The level of PGII in experimental group was significantly lower than that in control group (P<0.05). After treatment, 76 hP-positive patients turned negative, and PGI and PGI/PGII levels after Hp eradication were significantly lower than those before Hp eradication (P<0.05). PGII after Hp eradication was significantly higher than before (P<0.05). According to Pearson correlation analysis, Hp infection in elderly population was positively correlated with PGI and PGI/PGII levels, with correlation coefficients (r1=0.408,r2=0.412,P<0.05), and negatively correlated with PGII, with correlation coefficients (r=-0.469, P<0.05). Conclusions The Hp infection rate in patients with chronic gastritis is high, mainly in elderly men in Jianye District, Nanjing City.The levels of PGI and PGII in HP-positive patients are high, and the levels of PGI/PGII are low. The serum PG level can be used to evaluate the diagnosis and treatment effect of patients with Hp infection.

Objective: To investigate the epidemiological characteristics of suspected cases with occupational diseases and analyze the quality of occupational diseases report in Huzhou City from 2016 to 2020, so as to provide insights into supervision and early warning of occupational diseases. Methods: The epidemiological data pertaining to suspected cases with occupational diseases reported in Huzhou City from 2016 to 2020 were retrieved from the Occupational Disease and Health Risk Factors Monitoring Information System of China Disease Prevention and Control Information System, including gender, age, type of job, industry category, enterprise size and diagnosis. The percentages of identification, diagnosis and definitive diagnosis were calculated, and the distribution and diagnosis of suspected cases with occupational diseases were descriptively analyzed among different regions, industry categories and enterprise sizes. Results: A total of 264 398 people underwent occupational health examinations in Huzhou City from 2016 to 2020, and 322 suspected cases with occupational diseases were detected (12.18/104), including 179 cases with suspected pneumoconiosis (55.59%), 78 cases with suspected occupational ear, nose, throat and oral diseases (24.22%), 54 cases with suspected occupational poisoning (16.77%), 6 cases with suspected occupational skin diseases (1.86%), 3 cases with suspected occupational diseases caused by physical factors (0.93%) and 2 cases with other suspected respiratory diseases (0.62%). The 322 cases with suspected occupational diseases included 290 men (90.06%) and 32 women (9.94%), and had a mean age of (53.28±9.20) years. A total of 207 cases underwent occupational diseases diagnosis (64.29%), and 155 cases were definitively diagnosed with occupational diseases (74.88%). Among different counties (districts) in Huzhou City, the highest number of suspected cases with occupational diseases was reported in Changxing County (101 cases, 31.37%), with a diagnostic rate of 88.12%, and among all enterprises, the highest number of suspected cases with occupational diseases was reported in small enterprises (220 cases, 68.32%), with a diagnostic rate of 68.64%, while among all industry categories, the highest number of suspected cases with occupational diseases was reported in manufacture industry (228 cases, 70.81%), with a diagnostic rate of 56.14%. In addition, there was no suspected case with occupational diseases detected in agriculture, forestry, animal husbandry, fishery, wholesale/retail trade industry, or public administration, social security or social organizations. Conclusion Pneumoconiosis was the predominant type of suspected occupational diseases in Huzhou City from 2016 to 2020, and a low diagnostic rate was found. Improved supervision of occupational diseases control is strongly recommended among small enterprises to standardize the reporting system of suspected occupational diseases.

Objective:To design a new V-shaped forearm flap and to investigate the possibility of direct donor site closure and its value in the reconstruction of soft tissue defect after resection of buccal carcinoma.Methods:The new V-shaped forearm flap technique was applied in 10 patients with buccal carcinoma from October, 2018 to September, 2019. There were 6 males and 4 females aged from 35 to 63 years (48.3 years in average). Flap size ranged from 3.0 cm×5.0 cm to 4.0 cm×6.0 cm. Wound healing and the appearance forearm were recorded and evaluated three months after the surgery. Radial deviation angle, wrist flexion, ulnar deviation and dorsal extension were measured and calculated 3 months after the surgery. The wrist function was evaluated according to the Gartland-Werley scale. The recovery of wrist function was evaluated by comparing with the preoperative data.Results:Forearm donor sites were successfully closed without skin grafting in all 10 patients. Skin ischemia caused by excessive tension was observed at the incision edge in 3 patients, therefore leading to skin exfoliation and pigment loss without affecting wound healing. All patients were presented a cosmetic outcome during the follow-up period. No scar hyperplasia was observed. No significant difference was observed in perioperative wrist flexion angle, dorsal extension angle, radial deviation angle, ulnar deviation angle ( P>0.05)[data before surgery were (57.8±1.3) °, (58.4±0.7) °, (18.2±0.5) °, (28.5±1.1) ° respectively, and data 3 months after surgery were (53.2±2.1) °, (55.3±1.8) °, (16.4±0.4) °, (25.4±1.4) ° respectively]; Excellent and good rate of Gartland-Werley wrist score before and after surgery were both 100%. Conclusion:The new V-shaped free forearm flap can directly close small to medium forearm flap donor site. This method could avoid the trauma and complications of traditional free skin graft. The postoperative appearance on donor site is satisfactory and will not have adverse effects on wrist function. The new V-shaped free forearm flap is a novel method for repair of the defect of soft tissue defect after buccal cancer and it is worth to be applied in clinical practice.

Objective:To develop an diagnostic equipment with artificial intelligence (AI) real-time assistance under endoscopy (endoscopic AI equipment) for the detection of gastrointestinal protruding lesions, and to evaluate its performance and safety.Methods:From January to December 2017, at Endoscopy Center of West China Hospital, Sichuan University, the endoscopic images of individuals who underwent routine gastroscopy and colonoscopy were collected. The model was established based on convolutional neural network and the endoscopic AI equipment was developed. From June to December 2019, a prospective, single center, blinded and parallel controlled study was conducted to compare the differences in evaluation of protruding lesions of the same patient under gastroscopy or colonoscopy between endoscopist and the endoscopic AI equipment and to evaluated the impact of lesion size (lesions <5 mm and ≥5 mm) on the detection of endoscopic AI equipment. The main outcome measure was the detection time difference in reporting the protruding lesion between endoscopic AI equipment and endoscopist; and the secondary indicator was the accuracy of endoscopic AI equipment in detecting the protruding lesion. Wilcoxon rank sum test and chi-square test were used for statistical analysis.Results:A total of 71 582 white light endoscopy images were used for endoscopic AI equipment training, which included 41 376 images of protruding lesions. The endoscopic AI equipment was successfully developed and obtained the registration certificate of medical devices of the People′s Republic of China (Sichuan Instrument Standard, 20202060049). The accuracy, sensitivity, and specificity of endoscopic AI equipment in detecting protruding lesions were 96.4%, 95.1% and 92.8%, respectively. The detection time of each protruding lesions under gastroscopy of endoscopic AI equipment was 1.524 seconds faster than that of endoscopist; but the detection time of each protruding lesions under colonoscopy was 0.070 seconds slower than that of endoscopist, and the differences were statistically significant ( Z=-5.505 and -4.394, both P<0.01). The detection time of each protruding lesions under gastroscopy or colonoscopy of endoscopic AI equipment was not inferior to that of endoscopist. The detection rate of protruding lesions under colonoscopy by endoscopic AI equipment was 89.9% (249/277) and the sensitivity was 89.9%; the detection rate of protruding lesions under colonoscopy was 87.0% (450/517) and the sensitivity was 86.9%. There were no statistically significant differences in the detection time difference, sensitivity and missed diagnostic rate between the lesions <5 mm and ≥5 mm detected by endoscopic AI equipment under gastroscopy (all P>0.05). The sensitivity of endoscopic AI equipment in detecting the lesions ≥5 mm under colonoscopy was higher than that of lesions <5 mm (96.8% vs. 84.9%), and the missed diagnostic rate was lower than that of lesions <5 mm (3.2%, 3/94 vs. 15.1%, 61/405), and the differences were statistically significant ( χ2=9.615 and 9.612, both P=0.002). No adverse events on patients and medical staffs occurred, and there were no cases of equipment electricity leakage, and abnormal work reported during the use of endoscopic AI equipment. Conclusions:The endoscopic AI equipment can report the protruding lesions simultaneously with endoscopists, and the accuracy is close to 90%, which is expected to be a practical assistant for endoscopists to avoid missed detection of protruding lesions.

Objective: To assess the occupational health risk level of a small-scale furniture manufacturer, and to explore the applicability of the Singapore-developed semi-quantitative occupational risk assessment model for chemical exposure (Singapore model) in small-scale furniture manufacturers, and to provide a basis for the continuous occupational health management of manufacturers. Methods: A small-scale furniture manufacturer was selected as the study subject; an on-site occupational hygiene investigation was performed on the above manufacturer during April to June in 2017, and a risk assessment was carried out using the Singapore model. Results: The assessment results of the Singapore model indicated that risk levels of occupational exposure to harmful chemicals for the key positions in the workplace were inconsistent between the actual exposure level method and the exposure index method except for the following: high risk for formaldehyde exposure (risk level: 3.5 and 4.1, respectively) during woodworking process, high risk for dimethyl benzene exposure (risk level: 3.5 and 3.5, respectively) during burnishing process, medium risk for methyl benzene and dimethyl benzene exposure (risk level: 3.0 and 3.4, respectively) as well as for dimethyl benzene exposure (risk level: 3.0 and 3.3, respectively) during primer coating process, medium risk for methyl benzene exposure (risk level: 3.0 and 3.4, respectively) during gel painting process, and medium risk for cyclohexanone exposure (risk level: 2.8 and 2.8, respectively) during oil polishing process. The exposure index method yielded a higher risk level than the actual exposure level method, especially in the risk level of benzene exposure, which was rated as "high" and "very high" by the former but "low" by the latter. Conclusion The Singapore model is suitable for risk assessment of occupational exposure to harmful chemicals in small-scale furniture manufacturers, which can provide a basis for further prevention and control measures taken by manufacturers.

Objective: To understand the status of heat stroke in Huzhou and take preventive strategy and measures against the heat stroke. Methods: Case reports between 2013 and 2017 were collected. The differents between the population and age data from different types of heat stroke were tested by F test, and the genders tested by χ² test. The difference was statistically significant (P< 0.05) . Statistical significance by R 3.4.1. Results: A total of 1 307 patients were reported from 2013 to 2017, among which 878 cases (67.18%) were mild and 429 cases (32.82%) were severe. 15 fatalities (1.15%) were from the severe heat stroke cases. Male patients (947 cases, 72.46%) were more than female ones (360 cases, 27.54%) and the difference was statistical significant (χ²=8.541, P<0.05) . Heat stroke cases in age 45~55 (25.33%) accounted for the largest proportion and the difference was statistical significant (F=8.87, P<0.05) . The cases for heat stroke have increased year by year and have obvious seasonality, mainly in June to September. Conclusion Taken together, these findings indicated that the incidence rate of heat stroke were mainly mild and middle-aged men were susceptible to heat stroke in the city. However, to decrease the numbers of heat stroke, the relevant departments should take preventive strategy and measures against the heat stroke.
