Objective To investigate the prevalence of tension-type headache(TTH)in children and adolescents aged 0-19 years globally in 1990-2021,and to provide a basis for the prevention and treatment of TTH.Methods Based on the Global Burden of Disease Study data,the age-standardized prevalence distribution of TTH and its changing trend were analyzed among the children and adolescents aged 0-19 years,with different sexes,age groups,sociodemographic index(SDI)regions and countries/territories.Results The age-standardized prevalence rate(ASPR)of TTH in children and adolescents aged 0-19 globally in 2021 was 17 339.89/100 000,which was increased by 1.73%since 1990.The ASPR in females was slightly higher than that in males(1990:17 707.65/100 000 vs 16 403.78/100 000;2021:17 946.29/100 000 vs 16 763.09/100 000).The ASPR in adolescence was significantly higher than that in school-aged and preschool periods(1990:27 672.04/100 000 vs 10 134.16/100 000;2021:28 239.04/100 000 vs 10 059.39/100 000).Regions with high SDI exhibited a higher ASPR than the other regions,with significant differences in prevalence rates across different countries.From 1990 to 2021,there was a slight increase in global ASPR,with an average annual percentage change(AAPC)of 0.06%.Females experienced a smaller increase than males based on AAPC(0.04%vs 0.07%).There was reduction in ASPR in preschool and school-aged groups,with an AAPC of-0.02%,while there was a significant increase in ASPR in adolescence,with an AAPC of 0.07%.ASPR decreased in regions with low-middle and low levels of SDI,with an AAPC of-0.02%and-0.04%,respectively,while it increased in regions with middle SDI,with an AAPC of 0.24%.Conclusions There is a consistent increase in the ASPR of TTH in children and adolescents aged 0-19 years globally,with significant differences across sexes,age groups,SDI regions and countries/territories.

Objective To compare the efficacy of blood letting under pain point touch and ultrasound-guided puncture de-compression in the treatment of acute supraspinatus muscle calcifying tendinitis.Methods From January 2020 to January 2023,45 patients with acute supraspinatus muscle calcifying tendinitis were selected and divided into treatment group and control group.In the treatment group,a total of 22 patients were treated with ultrasound-guided puncture decompression,in-cluding 16 females and 6 males,aged from 20 to 64 years old(39.31±5.80)years old,11 on the left shoulder and 11 on the right shoulder.In the control group,there were 23 cases,including 15 females and 8 males,aged from 19 to 66 years old(40.67±6.13)years old,12 on the left shoulder and 13 on the right shoulder.The treatment was treated with pain point touch bloodletting therapy.The visual analog scale(VAS)pain score,University of California,Los Angeles(UCLA)shoulder system score and shoulder Constant-Murley score were used to evaluate the therapeutic effect before treatment,1 weeks,1 month and 3 months after treatment,respectively.Results One patient in the control group gave up follow-up for personal reasons after 1 week of treatment,and the other 44 patients completed all follow-up.Six months after treatment,there were no recurrence cases in both groups.After statistical analysis,VAS pain score,UCLA score and Constant-Murley score of the treatment group and the control group were significantly different from those before treatment(P＜0.05),and the improvement was more obvious in the treatment group.There was no statistical significance between the two groups(P＞0.05).Conclusion Bloodletting under pain point touch and ultrasound-guided puncture decompression are effective in the treatment of acute calcific supraspinatus tendinitis,with simple operation and low cost,which can effectively reduce local pain and effectively improve shoulder joint function.Primary hospitals can selectively operate treatment according to their own conditions.

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.

Objective: To clarify the epidemiological characteristics and spatiotemporal clustering dynamics of COVID-19 in Shanghai in 2022. Methods: The COVID-19 data presented on the official websites of Municipal Health Commissions of Shanghai during March 1, 2022 and May 31, 2022 were collected for a spatial autocorrelation analysis by GeoDa software. A logistic growth model was used to fit the epidemic situation and make a comparison with the actual infection situation. Results: Pudong district had the highest number of symptomatic and asymptomatic infectants, accounting for 29.30% and 35.58% of the total infectants. Differences in cumulative attack rates and infection rates among 16 districts (P<0.001) were significant. The rates were significantly higher in Huangpu district than in other districts. The attack rate of COVID-19 from March 1, 2022 to May 31, 2022 had a global spatial positive correlation (P<0.05). Spatial distribution of COVID-19 attack rate was different at different periods. The global autocorrelation coefficient from March 16 to March 29, April 6 to April 12 and May 18 to May 24 had no statistical significance (P>0.05). Our local autocorrelation analysis showed that 22 high-high clustering areas were detected in eight periods.The high-risk hot-spot areas have experienced a "less-more-less" change process. The growth model fitting results were consistent with the actual infection situation. Conclusion: There was a clear spatiotemporal correlation in the distribution of COVID-19 in Shanghai. The comprehensive prevention and control measures of COVID-19 epidemic in Shanghai have effectively prohibited the growth of the epidemic, not only curbing the spatially spread of high-risk epidemic areas, but also reducing the risk of transmission to other cities.

Since the pandemic outbreak of the COVID-19， there had been about 121 million confirmed cases and more than 2.6 million deaths， which had significantly affected the economies and health resources in more than 233 countries and regions. Currently， no effective therapeutic option is available for the COVID-19， andimplementation of public health interventions suffers inconvenience. Consequently， the development of COVID-19 vaccines remains crucial. This review updates the current research progression， advantages and disadvantages of inactivated vaccine， live attenuated vaccine， recombinant subunit vaccine， recombinant virus-vectored vaccine， DNA vaccine， and RNA vaccine for the COVID-19. It warrants joint research and development of vaccines on multiple platforms， which would facilitate better control and prevention of the COVID-19 epidemic.

In the current study, we sought to investigate whether T-type Ca channels (TCCs) in the brain are involved in generating post-anesthetic hyperexcitatory behaviors (PAHBs). We found that younger rat pups (postnatal days 9-11) had a higher incidence of PAHBs and higher PAHB scores than older pups (postnatal days 16-18) during emergence from sevoflurane anesthesia. The power spectrum of the theta oscillations (4 Hz-8 Hz) in the prefrontal cortex was significantly enhanced in younger pups when PAHBs occurred, while there were no significant changes in older pups. Both the power of theta oscillations and the level of PAHBs were significantly reduced by the administration of TCC inhibitors. Moreover, the sensitivity of TCCs in the medial dorsal thalamic nucleus to sevoflurane was found to increase with age by investigating the kinetic properties of TCCs in vitro. TCCs were activated by potentiated GABAergic depolarization with a sub-anesthetic dose of sevoflurane (1%). These data suggest that (1) TCCs in the brain contribute to the generation of PAHBs and the concomitant electroencephalographic changes; (2) the stronger inhibitory effect of sevoflurane contributes to the lack of PAHBs in older rats; and (3) the contribution of TCCs to PAHBs is not mediated by a direct effect of sevoflurane on TCCs.

Polysaccharide from Ganoderma applanatum has the activities of anti-tumor and enhancing immune function. There were no reports on antitumor effect of its intratumoral injection. In this study, the polysaccharide was extracted from G. applanatum by water extraction and alcohol precipitation, and purified by ceramic membrane after removing protein by Sevage method. The total polysaccharide content from G. applanatum(PGA)was about 63%. The combination of PGA and paclitaxel showed synergistic effect on cytotoxicity of 4 T1 cells at lower concentrations in vitro. In addition, the growth curve of 4 T1 cells showed that PGA could retard the growth of 4 T1 cells gradually. The PGA thermosensitive gel(PGA-TG)was prepared by using poloxamer 188 and 407. The gel temperature was 36 ℃, and the PGA-TG could effectively slow down the release rate of PGA in vitro. 4 T1 breast cancer-bearing mice were used as a model to evaluate the therapeutic effect of intratumoral injection of PGA combined with tail vein injection of nanoparticle albumin-bound paclitaxel(nab-PTX). In high and low dose PGA groups, each mice was given with 2.25, 1.125 mg PGA respectively, twice in total, and the dosage of paclitaxel was 15 mg·kg~(-1), once every 3 days, for a total of five times. The tumor inhibition rate was 29.65% in the high dose PGA-TG group, 58.58% in the nab-PTX group, 63.37% in low dose PGA-TG combined with nab-PTX group, and 68.10% in high dose PGA-TG combined with nab-PTX group respectively. The inhibitory effect in high dose PGA-TG group combined with nab-PTX on tumors was significantly higher than that in nab-PTX group(P<0.05). The results showed that paclitaxel therapy combined with intratumoral injection of PGA-TG could improve the therapeutic effect for 4 T1 mice and reduce the side effects of chemotherapy.

Pancreaticoduodenectomy (PD) is a standard surgical method for periampullary cancer.The hemorrhage is a dangerous complication after PD,how to effectively prevent and treat hemorrhage is a difficult point of pancreatic surgery,and also a key for reducing postoperative mortality.Four famous experts and their teams in surgical fiell explored prevention and treatment of the hemorrhage after PD from different angles based on clinical experiences.Professor Shen Boyong has conducted a discussion on early and Date hemorrhage after PD combined with previous successful experiences and prospective research data.Professor Chen Yajin suggested preventing hemorrhage in the aspects of anatomical resection,anastomosis and reconstruction,peritoneal drainage-tube placement and postoperative management based on different causes of hemorrhage.Professor Peng Bing paid attention to hemorrhage after laparoscopic PD,and supposed that intraoperative careful hemostasis,precise anastomosis,reasonable peritoneal drainage-tube placement and optimal perioperative management can reduce incidences of postoperative pancreatic fistula,biliary fistula and intra-abdominal infection,thereby lowering the incidence of hemorrhage.Professor Tan Guang respectively proposed processing strategies of hemorrhagc for grading A (mild at early stage),B (severe at early stage and mild at late stage) and C (severe at late stage).

OBJECTIVETo investigate mechanism of di-(2-ethylhcxyl)phthalate (DEHP) exposure in causing blood-testis barrier (BTB) impairment in rats.

METHODSTwo-months-old male SD rats were randomly divided into corn oil control group and DEHP (750 mg/kg) exposure group for daily intragastic treatment for 30 consecutive days. After the treatments the rats were examined for histomorphological changes of the testicle using HE staining and the expressions of the junction proteins N-cadherin β-catenin, occludin and connexin43 of the BTB using Western blot. In the in vitro study, the vitality and ROS generation level in Sertoli cells exposed to different concentrations of DEHP were examined with MTT and ROS assay kits, respectively, and Nrf2 and p-p38 expressions were detected with Western blot.

RESULTSCompared with the control group, the rats with DEHP exposure showed structural damage of the seminiferous tubule and polarity loss of the spermatids. DEHP exposure caused significantly decreased expressions of occludin and connexin43 but increased expressions of N-cadherin and β-catenin in the testicle tissues of the rats (P<0.05). The vitality of Sertoli cells was obviously decreased and ROS level increased significantly after exposure of the cells to increasing concentrations of DEHP, which also resulted in significantly up-regulated Nrf2 and p-p38 expressions (P<0.05).

CONCLUSIONSDEHP exposure causes increased oxidative stress in the Sertoli cells of the testis, activates p38 MAPK signaling pathway, and results eventually in impaired spermatogenesis in rats.
