Objective: To analyze the developmental trajectories of clustered health risk behaviors and their association with self-esteem and lonelinesss among junior high school students, so as to provide a reference for formulating comprehensive prevention and control measures of health risk behaviors among adolescents. Methods: In October 2023, 1 165 first year junior high school students from two schools of Jishou City in Hunan Province were selected by convenient sampling method for three follow up surveys (T1:October 2023; T2:April 2024; T3:October 2024). The Adolescent Health Risk Behavior Questionnaire, Rosenberg Self esteem Scale and Loneliness Scale were used to assess health risk behaviors, self esteem and loneliness, respectively. Latent growth curve modeling and latent growth mixture modeling were applied to analyze the developmental trajectories of clustered health risk behaviors among junior high school students. Logistic regression was used to analyze the association of the developmental trajectories of clustered health risk behaviors with self esteem and loneliness among junior high school students. Results: The overall developmental trajectories among junior high school students showed a declining trend (intercept=0.15, slope=-1.65, both P <0.05), with three heterogeneous categories:low risk improvement group ( n =862, 74.0%), moderate risk stable group ( n =260, 22.3%), and high risk deterioration group ( n =43, 3.7%). After adjusting the status of the left behind individuals，using the low risk improvement group as the reference category in multinomial Logistic regression analysis, results indicated that higher loneliness scores among junior high school students increased the risks of belonging to the moderate risk stable group ( OR=1.02, 95%CI =1.00- 1.04 ) and the high risk deterioration group ( OR=1.04, 95%CI =1.00-1.08), while higher self esteem scores reduced the risks of belonging to the moderate risk stable group ( OR=0.93, 95%CI =0.91-0.96) and the high risk deterioration group ( OR=0.88, 95%CI =0.83-0.94) (all P <0.05). Conclusions The overall trend of clustered health risk behaviors among junior high school students gradually improves, and the self esteem and loneliness are significant correlative factors. Targeted intervention measures should be developed for the junior high school students, with a focus on enhancing their self esteem and alleviating loneliness.

Evading host immunity killing is a critical step for virus survival. Inhibiting viral immune escape is crucial for the treatment of viral diseases. Serine/threonine kinase 39 (STK39) was reported to play an essential role in ion homeostasis. However, its potential role and mechanism in viral infection remain unknown. In this study, we found that viral infection promoted STK39 expression. Consequently, overexpressed STK39 inhibited the phosphorylation of interferon regulatory factor 3 (IRF3) and the production of type I interferon, which led to viral replication and immune escape. Genetic ablation or pharmacological inhibition of STK39 significantly protected mice from viral infection. Mechanistically, mass spectrometry and immunoprecipitation assays identified that STK39 interacted with PPP2R1A (a scaffold subunit of protein phosphatase 2A (PP2A)) in a kinase activity-dependent manner. This interaction inhibited DDB1 and CUL4 associated factor 1 (DCAF1)-mediated PPP2R1A degradation, maintained the stabilization and phosphatase activity of PP2A, which, in turn, suppressed the phosphorylation of IRF3, decreased the production of type I interferon, and then strengthened viral replication. Thus, our study provides a novel theoretical basis for viral immune escape, and STK39 may be a potential therapeutic target for viral infectious diseases.

[Purpose]To analyze the trend of incidence rates of gallbladder cancer in Qidong City of Jiangsu Province from 1972 to 2021.[Methods]The incidence data of gallbladder cancer from 1972 to 2021 were collected from the Qidong Tumour Registry database,the crude incidence rate(CR),age-standardized rate by Chinese standard population(ASRC),age-standardized rate by world standard population(ASRW)of gallbladder cancer were calculated.Trend analysis was per-formed using Joinpoint 4.9.1.0 software to calculate the average annual percentage change(AAPC)of gallbladder cancer incidence rates,and time trend analysis was performed on the overall inci-dence rate by sex and age.[Results]A total of 1 369 cases of gallbladder cancer occurred in Qi-dong City from 1972 to 2021,accounting for 0.93％of all malignant tumors.The overall CR of gallbladder cancer was 2.44/105 in 50 years,ASRC was 0.88/105 and ASRW was 1.45/105.The truncated rate of 35～64 years old was 1.98/105,the cumulative incidence of gallbladder cancer at 0～74 years old was 0.16％,and the risk of cumulative incidence of gallbladder cancer was 0.16％.CR was slightly higher in women than that in men,but after standardization it was slightly higher in men than that in women.The sex ratio of CR,ASRC and ASRW was 0.89,1.07 and 1.06,respectively.With the increase of age,the incidence of gallbladder cancer was also increased.The age of onset was slightly increased in last 50 years.In last 50 years,there was an upward trend in the overall incidence of gallbladder cancer,the incidence both for men and women,and the inci-dence of each age group.[Conclusion]The incidence of gallbladder cancer in Qidong City has increased considerably during the past 50 years,and continuing attention should be paid to the prevention and treatment of gallbladder cancer especially for the key populations.

[Purpose]To analyze the survival rate of breast cancer in Qidong City of Jiangsu Province from 1972 to 2019 and to predict the trend in the next 10 years.[Methods]The data of breast cancer collected from Qidong Cancer Registry from 1972 to 2019 were extracted.Observed survival rate(OSR),relative survival rate(RSR),age-adjusted relative survival(ARS)and average annual percentage change(AAPC)of breast cancer were calculated.ARIMA model was used to predict the trend of breast cancer survival rate.[Results]The 5-year RSR increased from 57.30％during 1972-1977 to 89.01％during 2014-2019,and the uptrend of RSR in the 8 periods was statistically significant(P＜0.001).The 5-year ARS increased from 48.12％during 1972-1977 to 85.64％during 2014-2019 with an AAPC of 1.85％(t=10.113,P＜0.001).The 5-year RSR during 1972-2019 for males was 85.22％,and for females was 74.51％.For females,the 5-year RSR in-creased from 56.44％during 1972-1977 to 88.93％during 2014-2019 with an AAPC of 1.29％(t=13.087,P＜0.001),and the 5-year ARS increased from 46.14％during 1972-1977 to 85.23％during 2014-2019 with an AAPC of 1.90％(t=10.369,P＜0.001).The 5-year RSR in the age groups of 25～34,35～44,45～54,55～64,65～74,and over 75 years old were 66.91％,74.69％,76.97％,75.52％,73.44％and 66.40％,respectively;the corresponding AAPCs of 5-RSR in above age groups were 1.02％(t=3.816,P=0.009),1.03％(t=4.936,P=0.003),1.23％(t=5.826,P=0.001),1.86％(t=5.997,P=0.001),2.13％(t=10.245,P＜0.001),and 1.44％(t=6.405,P=0.001),respectively.ARIMA modeling of survival trend prediction showed that 5-RSR and 5-ARS for breast cancer will be ascended to 98.76％and 98.33％by 2028,respectively.[Conclusion]The overall survival rate of registered breast cancer cases in Qidong City has been greatly improved and will be further improved in the future,more attention should be paid to the prevention and treatment of breast cancer.

[Purpose]To analyze the trend of non-Hodgkin's lymphoma incidence in Qidong City of Jiangsu Province from 1972 to 2021.[Methods]The data of non-Hodgkin's lymphoma inci-dence collected from Qidong Cancer Registry from 1972 to 2021 were extracted.The crude inci-dence rate(CR),age-standardized rate by Chinese standard population(ASRC)and by world standard population(ASRW),truncated incidence rate(35～64 years old)and cumulative incidence rate(0～74 years old)were calculated.The age-period-cohort model was used to analyze the age,period,and cohort effects of incidence in non-Hodgkin's lymphoma.Joinpoint 4.9.1.0 software was used to calculate the average annual percentage change(AAPC)of non-Hodgkin's lymphoma incidence for trend analysis.[Results]There were a total of 2 681 cases of non-Hodgkin's lymphoma re-ported in Qidong from 1972 to 2021.The CR,ASRC,ASRW,the truncated incidence(35～64 years old)rate and cumulative incidence rate(0～74 years old)were 4.78/105,3.35/105,3.30/105,5.20/105 and 0.37％,respectively.There were 1 589 male cases,with CR,ASRC and ASRW of 5.75/105,4.19/105 and 4.14/105,respectively;and there were 1 092 female cases,with CR,AS-RC and ASRW of 3.84/105,2.60/105 and 2.54/105,respectively.Age-period-cohort analysis showed that the net drift value of non-Hodgkin's lymphoma incidence was 1.65(95％CI:1.19～2.11),and age,period and cohort effects were all important influencing factors of non-Hodgkin's lymphoma incidence rate(all P＜0.05).The AAPCs for both sex,male and female of ASRC of non-Hodgkin's lymphoma in Qidong from 1972 to 2021 were 1.71％(95％CI:0.88％～2.54％,t=4.07),1.62％(95％CI:1.14％～2.11％,t=6.77),and 2.01％(95％CI:0.77％～3.26％,t=3.19),respectively,with a significant upward trend,and the differences were statistically significant(all P＜0.01).[Conclusion]Non-Hodgkin's lymphoma in Qidong City shows an overall increasing trend in the age-standardized incidence over the past 50 years,with a higher incidence in male and in the el-derly population.

Objective:To investigate the clinical characteristics of left-sided infective endocarditis (IE) without underlying valvular heart diseases (VHD).Methods:This was a retrospective study. Clinical data of 206 patients with left-sided IE (age: (50.4±16.1) years; 144 males (69.9%)) discharged from Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from June 2011 to May 2021 were retrospectively analyzed, including 129 cases with underlying VHD (IE+VHD group) and 77 cases without underlying VHD (IE group). The 6-month survival rate of patients after discharge was analyzed with Kaplan-Meier survival curve; and the 6-month survival rates of the patients with different sizes of endocardial vegetation and different treatment modalities in the IE group were further analyzed with log-rank method.Results:The proportions of patients with age ≥65 years old, arrhythmia and aortic valve involvement, and the in-hospital mortality in the IE group were significantly lower than those in the IE+VHD group ( P<0.05). However, the proportion of patients with fever and speech vague/limb movement disorder/headache, those with mitral valve involvement in the IE group were significantly higher than those in the IE+VHD group ( P<0.05). The median value of C-reactive protein (CRP) in the IE group was significantly higher than that in the IE+VHD group ( P<0.05). Nevertheless, the median value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in the IE group was significantly lower than that in the IE+VHD group ( P<0.05). There were as no significant differences in the positive rates of bacterial/fungal blood cultures and the proportion of patients with mitral and aortic valve involvement of endocardial vegetation between the two groups (all P>0.05). Kaplan-Meier survival curve analysis showed that there was no significant difference in 6-month survival rate of patients between the IE group and IE+VHD group (88.7% vs. 93.6%, log-rank χ2=0.887, P=0.346). In the IE group, the 6-month survival rate after discharge in patients with maximum diameter of vegetation ≤10 mm was higher than that in patients with maximum diameter of vegetation >10 mm (96.3% vs. 80.7%, log-rank χ2=4.111, P=0.043). There was no significant difference in 6-month survival rate between patients treated with antibiotics combined with surgery and those treated with antibiotics alone (96.2% vs. 78.6%, log -rank χ 2=2.976, P=0.084). Conclusion:Compared to left-sided IE patients with underlying VHD, patients without underlying VHD are likely to have a younger age, more mitral valve involvement and lower in-hospital mortality; for those patients with maximum diameter of vegetation ≤10 mm there is a higher survival rate, and antibiotics combined with surgery may help to improve the survival rate.

Objective:To compare the clinical manifestations,laboratory results,and imaging features between pyogenic spondylitis(PS) and tuberculous spondylitis(TS).Methods:This was a cross-sectional study. A total of 88 patients with infectious diseases of spine(IDS) admitted to Shanghai Sixth People′s Hospital from January 2021 to December 2023 were analyzed,including 61 PS cases(PS group) and 27 TS cases(TS group). The clinical manifestations,laboratory results,and imaging features were compared between two groups. The factors associated with PS were analyzed by multivariate logistic regression. The diagnostic efficacy for pathogen identification was compared between metagenomics next-generation sequencing(mNGS) and bacterial culture methods in PS and TS patients.Results:Compared with the TS group,the PS group had a higher age-adjusted Charlson comorbidity index(aCCI)[3.0(1.5,4.0) points vs. 2.0(1.0,3.0) points, Z=-2.189, P=0.029],shorter onset time of disease[1.0(0.8,3.0) months vs. 6.0(2.0,12.0) months,Z=-4.353, P<0.001],and higher median blood leukocyte counts and serum ferritin(SF) level(7.2×10 9/L vs. 6.3×10 9/L, Z=-2.652, P=0.008; 571.3 ng/ml vs. 266.0 ng/ml, Z=-4.773, P<0.001). The proportions of lumbar spine involvement,non-collapsed involved vertebrae,and bone bridges formed were all higher in the PS group compared to the TS group[68.8%(99/144) vs. 41.4%(29/70), χ2=14.628, P<0.001; 68.9%(42/61) vs. 18.5%(5/27), χ2=19.055, P<0.001; 41.0%(25/61) vs. 7.4%(2/27), χ2=9.921, P=0.002]. The proportions of thoracic spine involvement,severe vertebral collapse,severe narrowing of the involved intervertebral space,sequestrum,and paravertebral soft tissue calcification were all higher in the TS group compared to the PS group[52.9%(37/70) vs. 18.1%(26/144), χ2=27.463, P<0.001; 55.6%(15/27) vs. 13.1%(8/61), χ2=17.462, P<0.001; 74.1%(20/27) vs. 37.7%(23/61), χ2=9.907, P=0.002; 74.1%(20/27) vs. 18.0%(11/61), χ2=25.761, P<0.001; 51.9%(14/27) vs. 6.6%(4/61), χ2=23.599, P<0.001]. Multivariate logistic regression analysis indicated that a symptom duration<5.5 months( OR=30.644,95% CI: 2.022-464.529, P<0.05) and a leukocyte count>7.35×10 9/L( OR=48.653,95% CI: 2.045-1 157.721, P<0.05) indicated a higher likelihood of PS; while the vertebral collapse indicated a higher likelihood of TS( OR=0.025,95% CI: 0.001-0.638, P<0.05). The most common pathogen in the PS group was Staphylococcus aureus(31 cases,50.8%),followed by Streptococcus species(10 cases,16.4%). The positive rates of mNGS testing in the PS and TS groups were 84.1%(37/44) and 12/13,respectively,which were higher than those of conventional bacterial culture[77.8%(42/54)] and Mycobacteriumtuberculosis culture(2/11). Conclusions:Compared with the TS patients,the PS patients have shorter onset time,higher aCCI scores,higher blood leukocyte counts and SF levels,less vertebral collapse and intervertebral space narrowing,and more bone bridge formation. The TS patients have more dead bones and calcifications. The mNGS has a higher diagnostic efficacy than bacterial cultures for PS and TS.

Objective:To describe and analyze the incidence, mortality and epidemiological trends of liver cancer in China and selected regions worldwide, providing data references for liver cancer prevention and control.Methods:Data on the incidence, mortality, historical trends, and projected estimates for 2050 of liver cancer were extracted from the GLOBOCAN 2022 database. Epidemiological characteristics of liver cancer in China and other region were described and compared by region, age, sex and human development index (HDI). Spearman's test was used to examine the relationships between HDI and age-standardized incidence rate (ASIR) or age-standardized mortality rate (ASMR) across regions. The average annual percentage change (AAPC) in ASIR was calculated using Joinpoint regression analysis.Results:In 2022, the number of new cases and deaths of liver cancer in the global were 866 000 and 759 000 respectively, and the ASIR and ASMR were 8.6/10 5 and 7.4/10 5, respectively. Both ASIR and ASMR were higher in males than in females. In China, there were 368 000 new cases and 317 000 deaths in 2022, with an ASIR of 15.0/10 5 and an ASMR of 12.6/10 5. Globally, the incidence of liver cancer in males peaked in the 65-69 age group, while in Chinese males, two incidence peaks were observed in the 50-54 and 65-69 age groups. Among the elderly (≥65 years), the global ASIR and ASMR were 7.4 and 8.1 times higher, respectively, than those in the working-age population (15-64 years). In China, the ratios of ASIR and ASMR between the elderly and working-age populations were 5.9 and 7.0, respectively. Both ASIR and ASMR were negatively correlated with HDI (ASIR: r=-0.18, P=0.018; ASMR: r=-0.31, P＜0.001). From 2002 to 2017, ASIR of liver cancer showed a declining trend in both males and females in China, Japan, and South Korea (all P＜0.001), with AAPCs of -1.96% for Chinese males and -2.75% for Chinese females. In contrast, the United States experienced an increasing trend in ASIR, with AAPCs of 3.13% for males and 3.12% for females (both P＜0.001). Projections indicate that by 2050, the number of new cases and deaths globally will reach 1.564 million and 1.421 million, representing increases of 80.6% and 87.2% compared to 2022, respectively. In China, the number of new cases and deaths are projected to be 560 000 and 514 000, increases of 52.2% and 62.1% from 2022, respectively. Conclusions:The burden of liver cancer varies significantly across regions, sexes, and age groups worldwide. Incidence and mortality rates are negatively correlated with HDI. The global burden of liver cancer is expected to continue increasing, underscoring the need for enhanced comprehensive prevention and control strategies.

Objective:To describe the epidemiological characteristics and trends of lung cancer incidence in Qidong City, Jiangsu Province, China, between 1972 and 2021, and provide guidelines for prevention and control.Methods:Data on lung cancer with onset from January 1, 1972 to December 31, 2021 and coded as C33-C34 in the International Classification of Diseases (10th edition) were extracted from the tumor registry database of Qidong City. Population data of Qidong City for each year from 1972 to 2021 were extracted from the annual report of household registration of the Public Security Bureau of Qidong City. The crude incidence rate (CR), China age-standardized rate (ASRC), world age-standardized rate (ASRW), 35-64 years truncated rate, 0-74 years cumulative rate, and cumulative risk were calculated. Average annual percentage change (AAPC) was calculated by Joinpoint software for CR, ASRC, and ASRW. The age-period-cohort (APC) model was used to analyze the influence of age, period, and birth cohort on the changes in the incidence trend of lung cancer.Results:From 1972 to 2021, there were 26 996 patients of lung cancer in Qidong, accounting for 18.30% (26 996/147 519) of all cancer new cases. The CR of lung cancer was 48.13/10 5, the ASRC was 29.65/10 5, and the ASRW was 29.67/10 5. The truncated incidence of 35-64 years old was 42.64/10 5, the cumulative incidence rate between the ages between 0-74 years old was 3.71%, and the cumulative risk was 3.64%. There were 18 572 male patients, with the CR, ASRC, and ASRW being 67.15/10 5, 43.82/10 5, and 43.87/10 5, respectively. The number of female patients was 8 424, and the CR, ASRC, and the ASRW were 29.62/10 5, 17.63/10 5, and 17.55/10 5, respectively. Temporal analysis indicated significant upward trends in the ASRCs for both genders combined, males, and females, with AAPC values of 2.21%, 1.76%, and 2.98% (all P<0.001), respectively. Age-specific incidence rates increased with age, peaking at 275.34/10 5 in the 75+ years age group, with an increasing trend in all age groups and the greatest increase in the 75+ years age group, with an AAPC value of 3.53% ( P<0.001). The results of the APC model showed that the net drift value of lung cancer incidence was 2.06% (95% CI: 1.72%-2.41%), and the highest value of local drift was 3.93% (95% CI: 3.20%-4.68%) in the 80+ years old group. The risk of cancer increases with age in the age effect. The period effect of the incidence rate ratio (RR) value increased from 1.12 during 1997-2001 to 2.09 during 2017-2021. The cohort effect of the RR value for risk of incidence increased from 0.17 during 1892-1896 to 2.54 during 1987-1991. Conclusions:From 1972 to 2021, the incidence rate of lung cancer in Qidong City showed an upward trend. Age, period, and cohort are all major factors influencing the incidence of lung cancer. It is necessary to develop precise and comprehensive prevention and control strategies to curb this increasing trend of lung cancer incidence.

OBJECTIVE: To review the clinical characteristics of patients with traumatic spinopelvic dissociation (SPD) and explore the diagnostic and therapeutic methods. METHODS: A clinical data of 22 patients with SPD who underwent surgical treatment between March 2019 and August 2024 was retrospectively analyzed. There were 13 males and 9 females, with an average age of 35.5 years (range, 14-61 years). The causes of injury included falling from height in 16 cases, traffic accidents in 5 cases, and compression injury in 1 case. Sacral fractures were classified based on morphology into "U" type (9 cases), "H" type (7 cases), "T" type (4 cases), and "λ" type (2 cases). According to the Roy-Camille classification, there were 4 cases of type Ⅰ, 12 cases of type Ⅱ, 2 cases of type Ⅲ, and 4 cases of type Ⅳ. The Cobb angle was (35.7± 22.0)°. Sixteen patients were accompanied by lumbosacral trunk and cauda equina nerve injury, which was classified as grade Ⅱ in 5 cases, grade Ⅲ in 5 cases, and grade Ⅳ in 6 cases according to the Gibbons grading. The time from injury to operation was 2-17 days (mean, 5.7 days). Based on the type of sacral fracture and sacral nerve injury, 6 cases were treated with closed reduction and minimally invasive percutaneous sacroiliac screw fixation, 16 cases were treated with open reduction and lumbar iliac fixation (8 cases)/triangular fixation (8 cases). Among them, 11 patients with severe fracture displacement and kyphotic deformity leading to sacral canal stenosis or bony impingement within the sacral foramen underwent laminectomy and sacral nerve decompression. X-ray films and CT were reviewed during followed-up. The Matta score was used to evaluate the quality of fracture reduction. At last follow-up, the Majeed score was used to assess the functional recovery, and the Gibbons grading was used to evaluate the nerve function. RESULTS: All operations were successfully completed. All patients were followed up 8-64 months (mean, 20.4 months). Two patients developed deep vein thrombosis of the lower limbs, 2 had incision infections, and 1 developed a sacral pressure ulcer; no other complications occurred. Radiological examination showed that the Cobb angle was (12.0±6.8)°, which was significantly different from the preoperative one ( t=6.000, P<0.001). The Cobb angle in 16 patients who underwent open reduction was (14.9±5.5)°, which was significantly different from the preoperative one [(46.8±13.9)° ] ( t=8.684, P<0.001). According to the Matta scoring criteria, the quality of fracture reduction was rated as excellent in 8 cases, good in 7 cases, fair in 5 cases, and poor in 2 cases, with an excellent and good rate of 68.2%. Bone callus formation was observed at the fracture site in all patients at 12 weeks after operation, and bony union achieved in all cases at last follow-up, with a healing time ranging from 12 to 36 weeks (mean, 17.6 weeks). At last follow-up, the Majeed score was rated as excellent in 7 cases, good in 10 cases, fair in 4 cases, and poor in 1 case, with an excellent and good rate of 77.3%. One patient experienced a unilateral iliac screw breakage at 12 months after operation, but the fracture had already healed, and there was no loss of reduction. Among the 16 patients with preoperative sacral nerve injury, 11 cases showed improvement in nerve function (6 cases) or recovery (5 cases). CONCLUSION SPD with low incidence, multiple associated injuries, and high incidence of sacral nerve injury, requires timely decompression of the sacral canal for symptomatic sacral nerve compression, fractures reduction, deformities correction, and stable fixation.
