Objective To analyze the status of persistent human papillomavirus (HPV) infection and the distribution of viral subtypes in the Zhengzhou region. Methods Clinical data of 55239 patients who underwent HPV-DNA genotyping tests from 2018 to 2024 were collected. On the basis of HPV follow-up results, patients were divided into three groups: 849 cases of infection with the same HPV type, 255 cases of persistent infection with different HPV types, and 857 cases of transient HPV infection. Results Among the 9232 initially-screened patients who were positive with HPV, the high-risk HPV (HR-HPV) positive rate was 84.6% (7813/9232), and predominant subtypes were HPV-16 (20.8%), HPV-52 (17.2%), and HPV-53 (9.6%). The low-risk HPV (LR-HPV) positive rate was 15.4% (1419/9232), mainly HPV-81 (28.1%) and HPV-42 (27.0%). Among the 1961 follow-up cases, the rates of persistent and non-persistent infections with the same HPV type were 35.7% (701/1961) and 7.5% (148/1961), respectively. The rates of persistent and non-persistent infections with different HPV types were 10.9% (214/1961) and 2.1% (41/1961), respectively. Meanwhile, 43.7% (857/1961) tested negative upon follow-up. Among the 701 cases of persistent infection with the same HPV type, HR-HPV accounted for 85.7% (601/701), and LR-HPV accounted for 14.3% (100/701). Among the 214 cases of persistent infection with different HPV types, 89.7% (192/214) were high-risk transitions, and 10.3% (22/214) were low-risk transitions. Regardless of HPV types, HR-HPV was more likely to cause persistent infection than LR-HPV. In addition, over 60% of HR-HPV persistent infections resolved within 18 months, 30% developed into persistent infections, and only 15% of patients had persistent infections that last more than 24 months. Conclusion Persistent HPV infections are predominantly high-risk types. Most patients clear the infection within 18 months, approximately 30% develop persistent infections, and about 15% of patients have persistent infections that last more than 24 months. However, the HR-HPV persistent infection rates across different age groups slightly differ.

Objective To investigate the related factors of early neurological deterioration in elderly patients with thrombolysis for acute occlusive stroke of large intracranial vessels. Methods Clinical materials of 480 elderly patients with thrombolysis for acute occlusive stroke of large intracranial vessels were retrospectively analyzed. The National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the neurological function of patients within 72 hours after thrombectomy, and the patients were divided into deterioration group and non-deterioration group. The baseline materials were compared between the two groups, the factors of early neurological deterioration were analyzed, and the receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of risk. Results Among 480 elderly patients with thrombolysis for acute occlusive stroke of large intracranial vessels, 92 cases (19.17%) had early neurological deterioration; the blood glucose level, white blood cell count, incidence of dysphagia, and incidence of coma in the deterioration group were significantly higher than those in the non-deterioration group (P < 0.05); the Logistic regression analysis showed that high level of blood glucose (95%CI, 1.203 to 1.478), high level of white blood cell count (95%CI, 1.159 to 1.408), dysphagia (95%CI, 7.049 to 31.475), and coma (95%CI, 8.375 to 43.195) were risk factors for early neurological deterioration in elderly patients with thrombolysis for acute occlusive stroke of large intracranial vessels (OR>1, P < 0.05). ROC curve results showed that blood glucose, white blood cell count, dysphagia, and coma had certain predictive value for early neurological deterioration in elderly patients with thrombolysis for acute occlusive stroke of large intracranial vessels[the area under the curve (AUC) was 0.733, 0.708, 0.707 and 0.701]; the ROC curve showed AUC was 0.934, indicating that the model was reliable and stable. Conclusion Early neurological deterioration in elderly patients with thrombolysis for acute occlusive stroke of large intracranial vessels may be related to factors such as blood glucose, white blood cell count, dysphagia, and coma. Early risk assessment and relevant intervention measures can be taken clinically to improve prognosis.

Objective:To observe the feelings of listening to music and the importance of music in the daily life of post-lingual deaf adults with cochlear implants, and to explore the relevant influencing factors.Methods:This was a cross-sectional survey study. From January 2021 to August 2021,the Music-Related Quality of Life Scale was used to evaluate the music needs and music experiences of 63 post-lingual deaf adults who met the inclusion criteria, including 27 males and 36 females, aged (40.7±12.3) years, at the time of surgery (36.8±13.1) years, and with a preoperative hearing aid ineffective time of (3.9±5.8) years. Indicators analyzed included age, duration of ineffective preoperative hearing aid wear, preoperative music preference, duration of postoperative cochlear implant use, current hearing aid modality, and auditory rehabilitation outcomes. Whether the six factors mentioned above constituted an influence on the subjects′ music listening was investigated using SPSS 25.0 statistical software.Results:All of the observations in the scale were correlated with a single factor. The two sub-dimensions of music experience section were related to the effect of auditory rehabilitation. In the importance section, the effect of auditory rehabilitation was the influential factor of the dimension of "participation importance", and the preoperative enjoyment of music was the relevant influential factor of the dimension of "perceived importance". There was a significant difference between the groups when they were grouped by the above factors ( P value<0.05), while there was no statistically significance between the groups when they were grouped by other factors ( P value>0.05). Conclusions:Post-lingual deaf adults show the need and attempt to listen to music after cochlear implantation. The effectiveness of auditory rehabilitation and the degree of music preference preoperatively are two important factors that influence music listening in implant recipients. Once the level of auditory communication has been restored to a certain degree, it is important to pay more attention to the needs of music for implant recipients and train them in time, especially for those with music preferences preoperatively.

ObjectiveTo determine the influence of COVID-19 prevention and control on the epidemic characteristics and dynamics of notifiable infectious diseases in the first quarters， Zhejiang Province， and to explore more effective countermeasures against infectious diseases. MethodsDescriptive epidemiology was conducted to determine the change in notifiable infectious diseases during the prevention and control of COVID-19 in Zhejiang Province by retrieving the data of notifiable infectious diseases from 2017 to 2022 in the Chinese information system for disease control and prevention. Cumulative reported new cases of notifiable infectious diseases in the first quarters of 2017‒2019 were compared with that of 2020‒2022. ResultsA total of 546 753 cases of notifiable infectious diseases were newly reported in the first quarters of 2017‒2019， with an average incidence of 321.92/10⁵. In contrast， a total of 509 908 cases of notifiable infectious diseases were newly reported in the first quarters of 2020‒2022， during which the COVID-19 epidemic occurred， with an average incidence of 270.39/10⁵. The incidence in 2020‒2022 significantly declined by 51.53/10⁵， compared with that in 2017‒2019 （χ²=8 072.06， P<0.001）. In the first quarters of 2020‒2022， the average incidence of zoonotic diseases and vector-borne diseases decreased by more than 50%. In addition， the incidence of respiratory， enteric， blood-borne， and sexually transmitted diseases declined to certain degree. ConclusionThe decline in the newly reported cases of non-COVID-19 notifiable infectious diseases in the first quarters of 2020‒2022 indicates that the countermeasures against COVID-19 epidemic， such as multi-disease co-prevention， multi-sectoral collaboration， societal mobilization and personal hygiene and protection， may also decrease the incidence of multiple infectious diseases. It suggests the countermeasures are effective， which would provide evidence for routine prevention and control of infectious diseases in future.

Objective: To investigate the impact of COVID-19 infection and health related behaviors on the health related quality of life of children and adolescents aged 8-15 years in Nanjing, so as to provide a theoretical basis for improving HRQoL in children and adolescents. Methods: From December 2022 to January 2023, a total of 2 398 students aged 8-15 years from the third grade of primary school to junior middle school in Nanjing were selected by multistage random cluster sampling. The 3 level EuroQol 5 dimension Questionnaire Youth Vension (EQ-5D-Y-3L) was completed by the respondents on their own, and the parents assisted in completing the rest of the questionnaire. Results: The EuroQol-index(EQ-index) and Visual Analogue Scale (VAS) scores of being infected individuals were lower than those of uninfected and previously infected ( P <0.05). The proportion of being infected individuals reporting difficulty on "Pain/Discomfort" was higher than that of uninfected and previously infected individuals, and the proportion of reporting difficulty on "Mobility" was also higher than that of uninfected individuals ( P <0.05). Lack of parental companionship( OR=10.19, 95%CI =3.12-33.22), irregular breakfast consumption ( OR=10.63, 95%CI =3.20-35.25), and excessive screen time ( OR=8.24, 95%CI =3.02-22.51) increased the risk of difficulty on "Mobility" in being infected individuals ( P <0.05). Irregular breakfast consumption ( OR=1.93, 95%CI =1.31-2.84) and consumption of sweetened beverages and snacks (OR=1.56, 95%CI =1.17-2.10) increased the risk of having lower EQ index in previously infected individuals compared to uninfected individuals. Furthermore, consumption of sweetened beverages and snacks ( OR=1.57, 95%CI =1.21-2.05) and excessive screen time ( OR=1.49, 95%CI =1.12-1.98) also increased the risk of VAS scores being lower in previously infected individuals compared to uninfected individuals ( P <0.05). Conclusion The COVID-19 infection impairs HRQoL, and unhealthy behaviors deteriorate its negative impact. Healthy behaviors and lifestyles should be advocated to reduce the impact of COVID-19 infection on HRQoL.

Objective:To observe and analyze the macular microvascular system changes in unilateral pediatric uveitis (PU) and healthy contralateral eyes.Methods:A cross-sectional case-control study. From January 2019 to July 2021, 21 eyes of 21 patients with PU diagnosed in one eye (PU group), 21 unaffected contralateral eyes (contralateral eye group), and 21 age-matched volunteers with 21 eyes (NC group) during the same period were examined in Peking Union Medical College Hospital. Optical coherence tomography angiography was used to scan the 6 mm × 6 mm fundus macular area in the three groups of selected eyes to measure the vessel density of the superficial capillary plexus (SCP) and deep capillary plexus (DCP) of the retina, the area of the avascular zone (FAZ) in the fovea of the macula, the choroidal thickness under the fovea (SFCT), and the retinal thickness in the fovea of the macula (CRT). The device comes with a software choriocapillary flow measurement tool, which can obtain the macula's choriocapillary density (CCD) with the fovea as the center and the diameter of the annular area of 1.0 mm, 1.5 mm, and 3.0 mm, respectively. They were recorded as CCD-1.0, CCD-1.5, and CCD-3.0. The measurement data of multiple groups were compared by analysis of variance; if the variance of the three groups of data was not uniform, the Kruskal-Wallis test was used. Multiple linear regression analysis was used to evaluate the potentially related factors of CCD.Results:Compared with the contralateral eye group and the NC group, the vessel density of SCP ( H=-13.857,-25.500; P=0.043, P<0.001), DCP ( H=-15.333, -31.595; P=0.007, P<0.001) and CCD-1.0 ( H=-14.000,-16.214; P=0.040, 0.012) of the clinically quiescent PU group were significantly decreased. CRT and FAZ were not statistically different between PU and NC groups ( F=0.955; P=1.000, 0.661). Compared with the NC group, the mean vessel density of SCP and DCP in the contralateral eye group decreased, and the difference in DCP vessel density was statistically significant ( H=-16.262, P=0.004). There was no statistically significant difference between the CCD of two groups ( P=1.000). The SFCT of the PU group was significantly thicker than that of the NC group ( F=5.552, P=0.004), however, difference was not statistically significant from the fellow eye group ( F=5.552, P=0.270). The results of multiple linear regression analysis revealed that the CCD-1.0, CCD-1.5, and CCD-3.0 showed a linear correlation with the area of FAZ ( β=-0.494, -0.527, -0.566; P=0.015, 0.009, 0.010) and CRT ( β=-0.322, -0.466, -0.342; P=0.026, 0.002, 0.028). CCD-1.0 and CCD-1.5 showed a linear correlation with the vessel density of DCP ( β=0.277, 0.275; P=0.047, 0.045). Conclusion:Both retinal and choroidal microvasculature are abnormal in resting eyes with PU, and macular circulation disorders may be present in the unaffected fellow eye.

Objective:Through meta-analysis, the association of three common adipokines (leptin, adiponectin, and chemerin) with bone nutrition of senile osteoporosis (SOP) in China was systematically evaluated.Methods:CNKI, CBM, VIP, Wanfang, PubMed, Web of Science, Embase, Cochrane Library, and other databases were searched for articles published from the establishment of the database to July 30, 2022. After literature screening, data extraction, and quality evaluation of the included studies were independently conducted by two researchers, a meta-analysis was performed using RevMan5.4 and Stata17.0 softwares.Results:A total of 13 studies in the Chinese population were included, including 897 patients with SOP and 673 elderly with normal bone mineral density . The results of the meta-analysis showed that compared with the control group, the serum leptin levels were significantly lower ( MD -2.64, 95% CI -4.04 to -1.23, P < 0.001), chemerin levels were significantly higher ( MD 25.23, 95% CI 14.57 to 35.90, P < 0.001), and adiponectin levels were not significantly different ( MD -0.55, 95% CI -2.26 to 1.17, P > 0.05) in SOP patients. After subgroup analysis according to the measurement method, leptin levels remained lower in SOP patients than in the control group. Conclusions:Compared with the control group, leptin levels were lower and chemerin levels were higher in SOP patients. Therefore, dysregulation of adipokines may play an important role in the occurrence and development of SOP, and regulation of adipokine levels and functions may play a role in the treatment of SOP and the improvement of bone nutrition as a nutritional intervention.

Corona virus disease 2019 （COVID-19） has led to more than 500 million cases， including 6.19 million deaths. Mutated strains of SARS-CoV-2 （alpha， beta， gamma， delta and omicron） have successively emerged. Currently the omicron variant is gradually replacing the delta variant， driving a surge of cases in most countries including China， posing a great challenge to the prevention and treatment of COVID-19. In the face of the severe pandemic situation， a large number of non-medical volunteers are fighting on the front lines of the war against the pandemic and are vulnerable to exposure due to lack of professional knowledge. This paper introduces the routine skills training of volunteers and emergency response， aiming to provide behavioral guidance for non-medical volunteers in designated isolation facilities.

Objective:To investigate the relationship between serum vascular endothelial growth factor (VEGF) levels and white matter high signal and non-dementia vascular cognitive dysfunction in patients with cerebral small vascular disease (CSVD).Methods:Total 106 patients with CSVD who were admitted to the Department of Neurology of the First Affiliated Hospital of Xinxiang Medical College from April 2019 to December 2020 were enrolled.They were divided into vascular cognitive impairment no dementia group (VCIND group, n=47) and no vascular cognitive impairment group (N-VCI group, n=59)according to mini-mental assessment scale (MMSE), Montreal cognitive assessment (MoCA) scale and activity of daily living scale (ADL). Serum VEGF levels were detected by enzyme-linked immunosorbent assay (ELISA). The baseline data, serum VEGF levels, MoCA score and Fazekas score were compared between the two groups.The correlation between serum VEGF level and white matter high signal and cognitive function was analyzed.SPSS 19.0 software was used for data processing.The statistical methods were t-test, Chi square test, nonparametric test, Logistic regression analysis, Pearson correlation analysis and Spearman correlation analysis. Results:There were significant differences in serum VEGF level((464.18±114.58)pg/mL, (414.17±45.80)pg/mL, F=22.880), MoCA score((13.07±6.48), (20.17±4.06), F=17.920) and Fazekas score (4(3, 5), 3(1, 3), Z=-4.189)between the two groups (all P<0.05). The level of VEGF( β=0.008, OR=1.008, 95% CI=1.001-1.015, P<0.05) was the influencing factor of cognitive function in patients with CSVD .The level of VEGF was negatively correlated with the total score of MoCA, attention and calculation power, and orientation ability ( r=-0.345, -0.373, -0.445, all P<0.05) and it was positively correlated with the total Fazekas score and the Fazekas score of paraventricular and deep white matter ( r=0.392, 0.495, 0.302, all P<0.05). There was a linear trend between the high signal grade of paraventricular and deep white matter and VCIND (both P<0.05). Conclusion:Serum VEGF level is correlated with cognitive function and white matter hyperintensity in patients with CSVD.The increase of VEGF level may be a factor reflecting cognitive dysfunction.In addition, with the increase of white matter hyperintensity level, the risk of VCIND in CSVD is increased.

Multi-disciplinary team(MDT)mode is regarded as the key to standardized diagnosis and treatment of malignant tumors. The model, however, encounters such roadblocks in the current form of MDT organization, as costly clinical resources and time consumption, low efficiency, poor management of participating experts in MDT, and lack of enforceability of the therapeutic decisions made. This paper summarized the practical MDT experiences of the Affiliated Cancer Hospital of Shandong First Medical University. It introduced the construction of an intranet-based MDT system covering a large proportion of newly diagnosed malignant tumor patients, and the practices and achievements of such MDT management system under hospital administrative guidance. The authors proposed to use reporting ratio as the main assessment indicator in promoting MDT, and that to define the performance, responsibilities and rights in MDT practice. These measures aim at to upgrading individual behaviors of doctors to organizational behaviors of hospitals, and providing cancer patients with more standardized, comprehensive and personalized diagnosis and treatment decisions.
