Objective: To evaluate the effectiveness of varicella vaccine in varicella outbreaks and to analyze the influencing factors, and to provide a reference for making the targeted prevention and controlling measures. Methods: A total of 3 888 students with no history of varicella were selected from 2 schools with varicella outbreak in Guangdong Province in 2021, a retrospective cohort study was conducted by using questionnaire survey, rate ratio ( RR ) and vaccine effectiveness ( VE ) values were calculated and Logistic regression was uses to analyze the factors influencing the protective effect of varicella. Results: There were 138 confirmed cases of varicella among the participants. There was no significant sex difference in the vaccination rate( χ 2=1.36, P =0.51), but there was significant difference in the vaccinattion rate of different age groups( χ 2=555.82, P <0.01). The overall protective effect of VarV was 66.94%(95% CI =56.17%-77.71%), and the protective effect of 2 doses of vaccine( VE = 90.02% , 95% CI =83.13%-96.90%) was higher than that of 1 dose( VE =49.40%, 95% CI =32.36%-66.44%)( χ 2=24.93, P < 0.01 ). The high fever rates in the vaccinated and unvaccinated groups were 7.69% and 25.81%, with significant difference( χ 2= 6.29 , P <0.05). The rates of moderate and severe skin lesions of vaccinated and unvaccinated groups was 20.00% and 50.00%, respectively, and the difference was statistically significant( χ 2=11.32, P <0.01). The protective effects of varicella vaccine against high fever and moderate to severe rash were 70.19%(95% CI =42.11%-98.27%) and 60.00%(95% CI =38.15%-81.85%). Stratified analysis showed that there were significant differences in different years of vaccination( χ 2=37.87, P <0.05), while there were no significant differences in age of vaccination and vaccine manufacturer ( P >0.05). Conclusion Varicella vaccination can prevent chickenpox infection and reduce the severity of the disease. However, the efficacy of varicella vaccine was affected by vaccination years. It is recommended to improve the vaccination coverage of varicella vaccine to prevent the outbreak of the epidemic.

According to the current cervical cancer screening strategy and the World Health Orgnization cervical cancer diagnosis/screening guidelines, gene methylation will be included in the new guidelines in the future. However, the value of detecting DNA methylation at specific sites in the clinical specimens during the cervical cancer treatment remains to be discussed. This article summarised the role of DNA methylation in the development of cervical cancer and discusses the potential clinical application of methylation detection in the management of high-risk human papillomavirus (hrHPV) positive female patients. It is believed that methylation test can not only be used for the preliminary classification of hrHPV positive female patients, but also for the secondary triage of female patients with slight cytological abnormalities to determine the high risk of cervical intraepithelial neoplasia 3(CIN3) or cancer. It can also be used for the withdrawal test of women in the screening program to support the management of CIN.

The use of whole exome sequencing (WES) for the detection of disease-causing variants of genetic diseases and for non-invasive prenatal screening (NIPS) of fetal aneuploidies are two major clinical applications of next generation sequencing (NGS). This article has summarized the official documents developed and updated by the American College of Medical Genetics and Genomics (ACMG) on governing WES and NIPS. These include the development of expert consensus policies and position statements on an ongoing basis to guide clinical application of NGS technology and variant analysis, establish evidence-based practical resources, as well as standards and guidelines to govern diagnosis and screening. These ACMG documents are valuable references to Chinese geneticists, but direct adoption of these standards and guidelines may not be practical due to the differences in disease-associated variant frequencies in Chinese population, socioeconomic status, and medical practice between the two countries. It is hoped that this review could facilitate the development of NGS and NIPS standards and guidelines that are consistent with international standards and concordant with medical genetics practice in China to provide high-quality, efficient and safe clinical services for patients and their families with genetic diseases.

Epidemiological evidence suggests that patients with hypertension infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are at increased risk of acute lung injury. However, it is still not clear whether this increased risk is related to the usage of renin-angiotensin system (RAS) blockers. We collected medical records of coronavirus disease 2019 (COVID-19) patients from the First Affiliated Hospital, Zhejiang University School of Medicine (Hangzhou, China), and evaluated the potential impact of an angiotensin II receptor blocker (ARB) on the clinical outcomes of COVID-19 patients with hypertension. A total of 30 hypertensive COVID-19 patients were enrolled, of which 17 were classified as non-ARB group and the remaining 13 as ARB group based on the antihypertensive therapies they received. Compared with the non-ARB group, patients in the ARB group had a lower proportion of severe cases and intensive care unit (ICU) admission as well as shortened length of hospital stay, and manifested favorable results in most of the laboratory testing. Viral loads in the ARB group were lower than those in the non-ARB group throughout the disease course. No significant difference in the time of seroconversion or antibody levels was observed between the two groups. The median levels of soluble angiotensin-converting enzyme 2 (sACE2) in serum and urine samples were similar in both groups, and there were no significant correlations between serum sACE2 and biomarkers of disease severity. Transcriptional analysis showed 125 differentially expressed genes which mainly were enriched in oxygen transport, bicarbonate transport, and blood coagulation. Our results suggest that ARB usage is not associated with aggravation of COVID-19. These findings support the maintenance of ARB treatment in hypertensive patients diagnosed with COVID-19.

Objective:To investigate the clinical significance of inflammatory factors in bacterial infection children with glucose-6-phosphate dehydrogenase (G6PD) deficiency in PICU.Methods:A prospective cohort study was carried out from June 2014 to December 2017. 77 bacterial infection children with pediatric critical illness score less than 80 who were admitted to the PICU, were recruit in the study.The patient diagnosed as other basic diseases,with history of high-dose glucocorticoid use, discharged or died within 24 hours were excluded.The recruited patients were divided into G6PD deficiency group (observation group with 36 cases) and non-G6PD deficiency group (control group with 41 cases) according to the presence or absence of G6PD deficiency.Blood samples were taken at admission, 12 hand 24 h after hospitalization to detect the concentrations of tumor necrosis factor (TNF-α), interleukin 6 (IL-6), interleukin 10 (IL-10) andC-reactive protein (CRP). T test, χ2 test and Fisher exact test were used to analyze the changes of the above inflammatory factors, complications, prognosis, PICU stay time and hospitalization costs. Results:The levels of inflammatory factors in the observation group were significantly higher than those in the control group at admission, 12 and 24 hours after hospitalization, the differences were statistically significant (all P< 0.05). There was no statistically significant difference in thechangerate of inflammatory factors between the two groups during treatment; The PICU stay time of observation group was longer [(7.98 ± 6.55) vs (5.01 ± 6.21)] and the hospitalization cost (yuan) was higher [(36 634.09 ± 11 876.67) vs (31 571.42 ± 10 245.80)], P<0.05; Compared to the control group, the incidence ofsevere sepsis, septic shock, MODS increased significantly, and the curative rate decreasedsignificantly in observation group( P<0.05). Conclusions:G6PD-deficient children with bacterial infections had serious inflammatory reactions with poor prognosis and higher hospitalization costs and were susceptible to the occurrence of severe sepsis, septic shock and MODS.

Objective:To explore the serum levels of inflammatory cytokines and prognosis in severe acute infection children with glucose-6-phosphate dehydrogenase(G6PD) deficiency.Methods:A total number of 160 children with severe acute infections admitted to PICU of Guangxi Zhuang Autonomous Region Maternal and Child Health Hospital from June 2014 to December 2017 were selected as subjects in this study, including 80 children with G6PD deficiency(observation group) and 80 children without G6PD deficiency(control group). The changes of TNF-α, IL-6, IL-10 and CRP were dynamically monitored at 0-hour, 12-hour and 24-hour after admision, and the occurrences of sepsis, multiple organ dysfunction syndrome(MODS) were prospectively analyzed.Results:The levels of serum cytokines and CRP in the observation group were significantly higher than those in the control group at admission[TNF-α: (65.57±19.09) pg/ml vs.(46.53±20.34) pg/ml; IL-6: (98.90±29.02) pg/ml vs.(89.89±25.54) pg/ml; IL-10: (87.66±21.84) pg/ml vs.(76.34±19.01) pg/ml; CRP: (60.18±22.24) mg/L vs.(41.43±19.51) mg/L, respectively], and the differences between two groups were statistically significant( P<0.05). The levels of cytokines and CRP in the observation group were higher than those in the control group at 12 h and 24 h after treatment( P<0.01). Compared with the control group, the incidences of sepsis(82.50% vs 67.50%) and MODS(73.75% vs 58.75%) in the observation group increased, and the recovery rate(81.25% vs 92.50%) decreased, with statistical significance between two groups( P<0.05). Conclusion:Children with G6PD deficiency need to be paid more attention to inflammation, sepsis, MODS and the difficulty of treatment when they are infected.The potential mechanism may be related to oxidative stress.

Objective: To investigate the feasibility of parameter-optimized magnetic resonance imaging (MRI) as the first choice for imaging examination in patients with acute ischemic stroke (AIS), and to assess the effects of quality improvement (QI) measures on shortening the door-to-needle time (DNT). Methods: A retrospective case-control study was conducted. A total of 69 AIS patients hospitalized at the Department of Neurology of the People's Hospital of Wuzhou from August 2015 to July 2018 were enrolled in the study, and the head MRI was used as the first choice for imaging examination. All patients received the intravenous thrombolytic therapy with recombinant tissue plasminogen activator (rt-PA). Patients with AIS undergoing intravenous thrombolysis from August 2015 to March 2017 were included in the control group, and those receiving intravenous thrombolysis after QI measures from April 2017 to July 2018 were included in the experimental group. QI included informing the stroke team in advance by emergency physicians, treatment process changing from serial procedure to the parallel one, optimization of MRI scanning parameters, and use of rapid test instruments. The MRI scanning time was compared between the two groups. The DNT of the two groups was compared, and paired-samples t test was used. The proportion of patients who underwent MRI scan and DNT<60 min was compared between the two groups, and the χ² test was used. Results: Compared with the control group, the proportion of patients undergoing MRI scan in the experimental group was increased (82% vs 58%, χ²=4.58, P=0.032); MRI scanning time was shortened (4 min 37 s vs 10 min 21 s); DNT (min) was shortened (59.32±10.19 vs 93.48±24.81, t=7.189, P<0.01); and the proportion of patients with DNT<60 min was significantly increased (68% vs 6%, χ²=27.190, P<0.01). Conclusion Parameter-optimized MRI as the first choice for imaging examination in AIS patients with the onset time <4.5 h was feasible, and the DNT was significantly shortened by QI measures.

Objective To observe the changes of β-catenin expression in human skin fibroblasts (HSFs) after induced by oxidative stress, and to explore its possible roles in oxidative stress-induced premature senescence (SIPS) of HSFs. Methods Fibroblasts were isolated from the foreskin of a child and subjected to a primary culture. The fibroblasts of second to fourth passage were treated with various concentrations of H2O2 for 2 hours to establish an optimized model of stress-induced premature senescence, β-galactosidase assay kit was used to detect the activity of β-galactosidase in H2O2rinduced HSFs, RT-PCR and Western blot to measure the mRNA and protein expressions of β-catenin in control and senescent HSFs. Results Premature senescence of HSFs could be induced by the treatment with H2O2 of 150 μmol/L for 2 hours. The proportion of β-galactosidase-positive cells was (2.97 ± 0.25)% in control HSFs and (37.67 ± 1.53)% in senescent HSFs (P< 0.01). A significant increase was observed in the β-catenin/GAPDH protein ratio and β-catenin/GAPDH mRNA ratio in control HSFs compared with the senescent HSFs (0.62 ± 0.03 vs. 0.31 ± 0.01, t = 14.97, P < 0.01; 0.59 ± 0.04 vs. 0.29 ± 0.30, t = 10.06, P < 0.01). Conclusions The two-hour treatment with H2O2 of 150 μmol/L could induce the premature senescence of HSFs, and there is a notable decrease in the expression of β-catenin in prematurely senescent HSFs induced by oxidative stress, implying that β-catenin is an important target gene for the regulation of skin aging.
