Objective This article aims to investigate the association between hypertension and the risk of GSD by conducting a national multicenter study,a systematic review,and a meta-analysis.Methods The study was conducted in three stages.In the first stage,subjects were recruited for health examination in four hospitals in Chengdu,Tianjin,Beijing,and Chongqing,China,from 2015 to 2020,and the multivariate logistic regression analysis was used to investigate the association between hypertension and the risk of GSD in each center.In the second stage,Embase,PubMed,Wanfang Data,VIP,and CNKI databases were searched for related studies published up to May 2021,and a meta-analysis was conducted to further verify such association.In the third stage,the random effects model was used for pooled analysis of the results of the multicenter cross-sectional study and the findings of previous literature.Results A total of 633 948 participants were enrolled in the cross-sectional study,and the prevalence rate of GSD was 7.844%.The multivariate logistic regression analysis showed that hypertension was positively associated with the risk of GSD(P＜0.05).Subgroup analysis showed that there was no significant difference in the association between hypertension and GSD between individuals with different sexes,ages,and subtypes of GSD.A total of 80 articles were included in the systematic review and the meta-analysis,and the results showed that the risk of GSD was increased by 1.022 times for every 10 mmHg increase in diastolic pressure and 1.014 times for every 10 mmHg increase in systolic pressure.Conclusion Hypertension significantly increases the risk of GSD,and the findings of this study will provide a basis for the etiology of GSD and the identification of high-risk groups.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective:To investigate the clinical application value of injection of indocyanine green(ICG)via vasopuncture in fluorescence laparoscopic radical prostatectomy(FLRP).Methods:We retrospectively analyzed the clinical data on 50 cases of PCa treated by injection of ICG via vasopuncture in FLRP.The patients were aged(70.60±5.67)years old,with an average PSA value of(18.42±2.69)μg/L.During the operation,we injected ICG at 0.5 ml by vasopuncture through the vas deferens at each side of the scrotum,observed the visualized images of the vas deferens and seminal vesicles using normal high-definition,black-and-white fluorescence,green fluorescence,and color fluorescence respectively,and then isolated the adherent seminal vesicles under the laparoscope.Results:A total of 93 injections of ICG were completed,86 bilaterally,4 on the right and 3 on the left.The vas defer-ens and seminal vesicles were visualized in 41 cases(60 sides,64.52%),19 bilaterally,7 on the right and 15 on the left.Spillage of the fluorescent agent occurred in 9 cases during the incision of the bladder neck and adhesion of the seminal vesicles was found intra-operatively in 10 cases,in which the seminal vesicles were all quickly located by fluorescence visualization.No rectal injury occurred during the surgery.Mild scrotal subcutaneous bruises were observed in 2 cases,with a postoperative pathological Gleason's score of 7.44±0.88.Conclusion:Injection of ICG by vasopuncture is minimally invasive and safe.ICG-mediated near-infrared imaging and real-time fluorescence imaging of the vas deferens and seminal vesicles can achieve precise positioning and removal of the seminal vesicles and prostate gland without causing rectal injury.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Clinical data of 210 patients with early colorectal cancer and precancerous lesion treated by endoscopic submucosal dissection (ESD) in the Digestive Endoscopy Center of the Seventh Medical Center of Chinese PLA General Hospital from January 2015 to March 2018 were collected and analyzed retrospectively. Patients were divided into two groups according to the age: the elderly group (≥65 years old, 100 cases) and the non-elderly group (<65 years old, 110 cases). The en bloc resection rate, complete resection rate,and curative resection rate of the elderly group were 92.0% (92/100), 91.0% (91/100) and 89.0% (89/100), respectively. The above indicators of the non-elderly group were 90.9% (100/110) ( P=0.972), 90.0% (99/110) ( P=0.991) and 88.2% (97/110) ( P=1.000), respectively. The incidence of intraoperative perforation in the elderly group was 4.0% (4/100) and in the non-elderly group was 6.4% (7/110) ( P=0.543). Delayed postoperative bleeding rate was 2.0% (2/100) in the elderly group, and 0 (0/110) in the non-elderly group ( P=0.226). ESD is effective and safe in treating early colorectal cancer and precancerous lesion in elderly patients.

The COVID-19 pandemic is still ongoing in the world, the risk of COVID-19 spread from other countries or in the country will exist for a long term in China. In the routine prevention and control phase, a number of local COVID-19 epidemics have occurred in China, most COVID-19 cases were sporadic ones, but a few case clusters or outbreaks were reported. Winter and spring were the seasons with high incidences of the epidemics; border and port cities had higher risk for outbreaks. Active surveillance in key populations was an effective way for the early detection of the epidemics. Through a series of comprehensive prevention and control measures, including mass nucleic acid screening, close contact tracing and isolation, classified management of areas and groups at risk, wider social distancing and strict travel management, the local COVID-19 epidemics have been quickly and effectively controlled. The experiences obtained in the control of the local epidemics would benefit the routine prevention and control of COVID-19 in China. The occurrence of a series of COVID-19 case clusters or outbreaks has revealed the weakness or deficiencies in the COVID-19 prevention and control in China, so this paper suggests some measures for the improvement of the future prevention and control of COVID-19.

This manuscript aims to investigate the effects of resibufogenin on the proliferation, migration and invasion of human hepatocellular carcinoma cells and its related mechanisms. MTT assay was used to determine the inhibitory effect of resibufogenin on the growth of four hepatocellular carcinoma cells in vitro. Wound-healing assay and Transwell assay were used to evaluate the migration and invasion ability of resibufogenin on MHCC-97H cells. Western blot assay was used to detect the expression of migration and invasion related proteins in MHCC-97H cells treated with different concentrations of resibufogenin. The results showed that resibufogenin significantly inhibited the proliferation of hepatocellular carcinoma cells in vitro. The half maximal inhibitory concentration (IC₅₀) values on MHCC-97H, HepG2, SK-Hep-1 and Huh-7 cells were 0.55 ± 0.06, 2.83 ± 0.24, 5.25 ± 0.49, 14.89 ± 2.28 μmol·L^-1, respectively. Resibufogenin also suppressed the migration and invasion of MHCC-97H cells in a concentration-dependent manner. The protein expression of integrin α2, integrin α6, integrin β1, N-cadherin, matrix metalloproteinase 2 (MMP2) and transcription factor Twist in MHCC-97H cells were decreased significantly with the increase of the concentration of resibufogenin, while the protein expression of E-cadherin increased. In addition, we found that p-PI3K/PI3K and p-AKT/AKT ratios were significantly reduced after treatment with resibufogenin. In conclusion, resibufogenin can inhibit the proliferation, migration and invasion of hepatocellular carcinoma MHCC-97H cells in vitro, which is related to the regulation of intracellular migration and invasion protein expression and PI3K/AKT signaling pathway.
