Objective · To investigate the intention of quitting smoking and influencing factors among husbands in gestational households in Shanghai and provide a scientific basis for establishing smoking cessation strategies. Methods · Pregnant women and their spouses who received antenatal examination in 5 hospitals in Shanghai were asked to finish two versions of questionnaires respectively. Basic demographic information, smoking history, history of smoking cessation and intention of quitting smoking were investigated. The database was set up by EpiData 3.1, and data were analyzed by SPSS 22.0, such as descriptive analysis, χ2 test (univariate), and Logistic regression analysis (multivariate). Results · A total of 282 questionnaires were sent to smoking husbands and 266 effective questionnaires got back with the effective rate of 94.3%. Among them 34.2% smoking husbands had intention of quitting smoking, 18.4% were trying to quit, and 22.9% had tried to quit before. Single-factor analysis showed that influencing factors for intention of quitting smoking among smoking husbands in gestational households included the daily cigarette consumption, overall opinion for smoking, the knowledge about the harm of passive smoking to pregnant women and fetuses, having smoking cessation experience or not, how many people smoking among five intimate friends except family members (P<0.05). Multivariate Logistic regression analysis showed that intention of quitting smoking had relationship with the daily cigarette consumption (OR = 0.456, 95% CI: 0.245 ~ 0.852), overall opinion for smoking(OR=2.443, 95% CI: 1.008 ~ 5.921), having smoking cessation experience or not (OR =0.316, 95% CI: 0.162 ~ 0.616). Conclusion · Intention of quitting smoking is relatively strong in gestational households. It is recommended to strengthen the education of tobacco control for smoking husband in gestational households, and encourage smokers who had smoking cessation experience before to quit smoking again.

Aim To study the apoptosis effect of Sir-aitia grosvenorii extract on human lung cancer cells A549 and its mechanisms.Methods MTT assay was applied to determine A549 cell proliferation.Hoechst 33258 staining was applied to investigate morphological changes in A549 cells.To find out the cause of cell growth inhibition,several experiments on cell cycle distribution and apoptosis were performed by flow cy-tometry analysis.The expression of p21 and Bcl-2 was determined by Western blot.Results Flow cytometry analysis showed that treatment with mogrol arrested A549 cells in the G0 /G1 phase and induced apoptosis. After treatment with Siraitia grosvenorii extract,West-ern blot experiment showed cell cycle regulator p21 was up-regulaed,while the apoptosis inhibitor Bcl-2 was down-regulated.Conclusion Treatment with Siraitia grosvenorii extract arrests the A549 cells at G0 /G1 phase and induces apoptosis that may contribute to the anti-proliferation activity of mogrol through the regula-tion of p21 and Bcl-2 expression.

Objective:To investigate the clinical characteristics,treatment and prognosis of primary pe-noscrotal extra-mammary Paget’s disease (PSPD).Methods:The clinical and pathological data of 22 cases of primary PSPD were retrospectively reviewed.Survival rate of the overall patients,the invasive patients,and the patients with positive surgical margin or negative surgical margin were analyzed with Ka-plan-Meier survival curve method.Results:Among all the patients with primary PSPD,the median age of onset was 64.5 (39 -84)years,the median time of disease duration was 40 (2 -300)months,and the median long diameter of lesion was 4.75 (1 -10)cm.In the study,12 patients (54.5%)were in pathological stage A1,6 patients (27.3%)were in pathological stage A2,and 4 patients (18.2%) were in pathological stage B.Scrotum and penile of most patients (n =12,54.5%)were involved,5 patients (22.7%)were scrotum only,and 5 patients (22.7%)were penile only.Erythema (n =18, 81.8%),itchiness (n =16,72.7%),ulcerate (n =12,54.5%),exudation (n =11,50.0%),and pain (n =4,18.2%)were the major manifestations.All the patients with primary PSPD were treated with wide surgical excision.The rate of invasive patients was 77.3% (n =17).Of them,6 patients had positive surgical margin.The surgical margins of non-invasive patients were all negative.Twelve patients exhibited local recurrence or/and metastases,and the status of surgical margins (P =0.015)and the depth of invasion (P =0.010)were important risk factors.Inguinal lymph nodes were generally in-volved.The difference of the delay of diagnosis between metastasis and non-metastasis was significant (P =0.040).The 5-year survival rates of the overall and invasive patients were 33.7% and 27.9%, respectively.The patients with positive surgical margin had poor prognosis.Conclusion:Primary PSPD, with the characteristics of long duration,high invasive tendency and high incidence of local recurrence or metastases,generally occurs in the elderly.Surgery should be performed at first.The delay of diagnosis, positive surgical margins and the involvement of inguinal lymph node are important risk factors.Biopsy, frozen section and inguinal lymph node biopsy (ILNB)can standardize diagnosis and treatment.

Background and Objectives: Venous thromboembolism (VTE), consisting of deep vein thrombosis (DVT) and pulmonary embolism (PE), is highly prevalent in in-hospital HF patients and contributes to worse prognoses. However, the risk of VTE in out-patients with HF in long-term period is controversial. This study aimed to evaluate the associations between HF and the risk of VTE in a long-term follow-up duration. Methods: We searched for studies investigating the risk of VTE, PE, and DVT in patients with HF before April 15, 2020, in PubMed, MEDLINE, and Embase databases. Cohort studies and post hoc analysis of RCTs were eligible for inclusion if they reported relative risk of VTE, DVT or PE in patients with HF in more than 3-month follow-up period. Results: We identified 31 studies that enrolled over 530,641 HF patients. Overall, patients with HF were associated with an increased risk of VTE (risk ratio [RR]=1.57, 95% confidence interval [CI]=1.34–1.84) and PE (RR=2.00, 95% CI=1.38–2.89). However, the risk of DVT was not significantly increased in HF patients (RR=1.33, 95% CI=0.67–2.63). Subgroup analysis showed that patients with chronic HF (RR=1.54, 95% CI=1.32–1.80) had a higher risk of VTE than those with acute HF (RR=0.95, 95% CI=0.68–1.32). Conclusions In conclusion, HF was an independent risk for VTE and PE but not DVT in a longterm follow-up period. Patients with chronic HF were prone to suffer from VTE than acute HF.

Objective: To analyze the prevalence of comorbidity of spinal curvature abnormality and malnutrition among primary and secondary school students aged 10-18 years in Tianjin in 2023, so as to provide scientific basis for the combined prevention of common diseases and multiple diseases among students and the construction of school health system. Methods: In September to October 2023, 31 884 primary and secondary school students aged 10 to 18 years in Tianjin were selected using stratified cluster random sampling. Abnormal spinal curvature in children and adolescents was assessed by Sereening of Spinal Curvature Abnormality of Children and Adolescents, while stunting, wasting, overweight, and obesity were determined according to the Screening for Malnutrition among Schoolage Children and Adolescents and Screening for Overweight and Obesity among Schoolage Children and Adolescents. The χ2 test was used to compare betweengroup differences in coprevalence, and multiple Logistic regression models were used to analyze the risk of different comorbidity types in different clusters. Results: The coprevalence of spinal curvature abnormality and malnutrition among primary and secondary school students in Tianjin was 1.6%, which was higher for girls than boys (1.8%, 1.4%), higher (2.5%) for senior high schools than for junior high schools and elementary schools (2.0%, 0.5%), and higher in rural than in urban areas (2.1%, 1.1%) (χ2=9.45, 141.92, 46.94, P<0.05). Multiple Logistic regression models showed that junior high school girls had a higher risk of incorrect posture comorbid with stunting and wasting (OR=4.52, 95%CI=1.84-11.06) and incorrect posture comorbid with overweight and obesity (OR=2.67, 95%CI=1.74-4.10) than boys, and that scoliosis/sagittal spinal abnormality comorbid with stunting and wasting (OR=0.10, 95%CI=0.02-0.44) risk was lower than that of boys, senior high school girls had a lower risk of scoliosis/sagittal spinal abnormality comorbid with overweight and obesity (OR=0.27, 95%CI=0.11-0.66) (P<0.05). Conclusions The coprevalence of spinal curvature abnormality and malnutrition is specific among primary and secondary school students in Tianjin, and the comorbidity type varies by gender and education stage. There is a need to increase prevention and control of spinal curvature abnormalities in school health working, intensive screening of key populations, and timely intervention.

OBJECTIVE: To investigate the inhibitory effects of dihydromyricetin on the proliferation and migration of gastric cancer BGC-823 cells and explore the molecular mechanisms. METHODS: BGC-823 cells in routine culture were treated with different concentrations of dihydromyricetin (0, 40, 60, 80, 100, and 120 μg/mL) for 24 h, and the changes in cell viability were detected using CCK-8 assay; colony forming assay and Transwell assay were performed to assess the changes in colonyforming and migration abilities of the cells, respectively. The levels of MMP-2 and MMP-9 in the treated cells were determined using ELISA, and Western blotting was used to detect the expressions of E-cadherin, N-cadherin, cyclin D1, cyclin E1, HSP70 and HMGB1 and the phosphorylation levels of Akt and Stat3. RESULTS: CCK-8 assay showed that dihydromyricetin treatment dose-dependently inhibited the viability of BGC-823 cells ( CONCLUSIONS Dihydromyricetin inhibits the proliferation and migration of BGC-823 cells through suppressing the activation of Akt/stat3 signaling pathways and HMGB1 expression.

OBJECTIVE: To investigate the effect of calenduloside E on lipopolysaccharide (LPS)-induced inflammatory response in RAW264.7 cells and explore the underlying molecular mechanism. METHODS: CCK-8 assay was used to examine the effect of different concentrations of calenduloside E (0-30 μg/mL) on the viability of RAW264.7 cells. The release of the pro-inflammatory cytokines tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in RAW264.7 cells in response to pretreatment with 6, 8, and 10 μg/mL calenduloside E for 2 h followed by stimulation with 100 ng/mL LPS was detected using enzyme-linked immunosorbent assay (ELISA). The expression levels of iNOS and COX-2 and the activation of JAK-stats, MAPKs and NF-кB signaling pathways in the treated cells were determined using Western blotting. A reactive oxygen species (ROS) detection kit was used to detect ROS production in the cells, and the nuclear translocation of the transcription factor stat3 was observed by laser confocal microscopy. RESULTS: Calenduloside E below 20 μg/mL did not significantly affect the viability of RAW264.7 cells. Calenduloside E dose-dependently decreased the expression levels of iNOS and COX-2 induced by LPS, inhibited LPS-induced release of TNF-α and IL-1β, and suppressed LPS-induced JAK1-stat3 signaling pathway activation and stat3 nuclear translocation. Calenduloside E also significantly reduced ROS production induced by LPS in RAW264.7 cells. CONCLUSIONS Calenduloside E inhibits LPS-induced inflammatory response by blocking ROS-mediated activation of JAK1-stat3 signaling pathway in RAW264.7 cells.

OBJECTIVETo investigate the efficacy of brachytherapy for patients with localized prostate cancer and the influence factors.

METHODSThere were 61 patients with localized prostate cancer were treated with brachytherapy between April 2001 and March 2011 in Department of Urology, Peking University First Hospital, including 11 patients who received combined external beam radiotherapy. The mean age was 75.2 years (range 57-84 years). Clinical stage was T1c in 12 patients, T2a in 18 patients, T2b in 17 patients, and T2c in 14 patients. Long-term follow-up was carried on all patients for prostate specific antigen (PSA) and adverse effects. Kaplan-Meier survival curves, Log-rank test and univariate Cox proportional hazard regression analysis was used to examine the factors associated with the treatment efficacy.

RESULTSThe median follow-up was 49 months (range 9-126 months). The mean PSA before treatment and the mean nadir PSA after operation were (17.80 ± 14.44) µg/L and (1.16 ± 1.15) µg/L, respectively. The PSA of 58 patients (95.1%) reached a nadir < 4.0 µg/L, which was even < 1.0 µg/L in 37 patients (60.7%). The mean time to reach the nadir PSA was 11.6 months after operation. The short-term adverse events after operation included fever in 4 patients, hematuria in 7 patients, and hematochezia in 4 patients. The most common long-term adverse event was urinary irritation (31.1%); other long-term adverse events were rare, including hematochezia, hematuria, urinary incontinence, urinary retention, mild diarrhea and radiation enteritis. The estimated mean biochemical recurrence-free survival after brachytherapy was 41.0 months (95% CI: 31.05-50.94 months). The mean nadir PSA after operation were 1.32 µg/L in the 11 patients who received combined external beam radiotherapy, and their estimated mean biochemical recurrence-free survival was 38 months. Patients with nadir PSA < 1.0 µg/L had a significant longer biochemical recurrence-free survival than those with nadir PSA between 1.0 µg/L and 4.0 µg/L (42.9 vs. 32.0 months, χ² = 4.445, P = 0.035).

CONCLUSIONSBrachytherapy is an effective treatment strategy for localized prostate cancer, with relatively low rate of severe adverse events. After brachytherapy, a nadir PSA < 1.0 µg/L might indicate a better prognosis.
