Objective To understand the mortality and potential life loss due to coronary heart disease (CHD) and stroke in Wujiang District, Suzhou from 2011 to 2022, and to provide strategies and basis for the prevention and treatment of CHD and stroke. Methods We collected the data of death cases due to CHD and stroke from the death monitoring system in Suzhou from 2011 to 2022. The mortality of CHD and stroke, potential years of life lost (potential years of life lost , PYLL), average years of life lost (average years of life lost , AYLL) and potential years of life lost rate (potential years of life lost rate , PYLLR) were calculated to analyze the development trend of death and disease burden of CHD and stroke. Results From 2011 to 2022, the crude mortality of CHD was 31.91/10 million, and that of stroke was 118.93/10 million. CHD and stroke mortality rates both showed an upward trend（P＜0.05, a statistically significant trend）. From 2011 to 2022, the mortality rate of CHD and stroke in Wujiang District increased rapidly with the increase of age. From 2011 to 2022, the disease burden caused by CHD totaled 11005 person-years, with PYLLR of 1.26% and AYLL of 12.34 years per person. The PYLL caused by stroke was 13 587.5 people-years, the PYLLR was 1.55%, and the AYLL was 8.93 years per person. PYLL, PYLLR and AYLL all decreased in women（P<0.05）, with no significant change in men（P>0.05）. Conclusion From 2011 to 2022, the mortality rate of CHD and stroke in Wujiang District appeared a tendency towards a rise, effective intervention and prevention measures should be taken among elderly and male residents.

Objective:To investigate the role of an inflammatory microenvironment induced by Porphyromonasgingivalis ( P. gingivalis) in the occurrence of esophageal squamous cell carcinoma (ESCC) in mice. Methods:A total of 180 C57BL/6 mice were randomly divided into 6 groups, i.e. control group, P. gingivalis group, 4NQO group, 4NQO + P. gingivalis group, 4NQO + P. gingivalis + celecoxib group, and 4NQO + P. gingivalis + antibiotic cocktail (ABC, including metronidazole, neomycin, ampicillin, and vancomycin) group, with 30 mice in each group, using the random number table. All mice were normalized by treatment with ABC in drinking water for 2 weeks. In the following 2 weeks, the mice in the control group and the P. gingivalis group were given drinking water, while the other 4 groups were treated with 30 μg/ml 4NQO in the drinking water. In weeks 11-12, the mice in the P. gingivalis group, the 4NQO + P. gingivalis group, the 4NQO + P. gingivalis + celecoxib group, and the 4NQO + P. gingivalis + ABC group were subjected to ligation of the second molar in oral cavity followed by oral P. gingivalis infection thrice weekly for 24 weeks in weeks 11-34. In weeks 13-34, the mice in 4NQO + P. gingivalis+celecoxib group and 4NQO + P. gingivalis + ABC group were administered with celecoxib and ABC for 22 weeks, respectively. At the end of 34 weeks, gross and microscopic alterations were examined followed by RT-qPCR and immunohistochemistry to examine the expression profiles of inflammatory- and tumor-molecules in esophagi of mice. Results:At 34 weeks, 4NQO treatment alone did not affect the foci of papillary hyperproliferation, diseased area, and the thickness of the esophageal wall, but significantly enhanced the foci of hyperproliferation (median 1.00, P＜0.05) and mild/moderate dysplasia (median 2.00, P＜0.01). In addition, the expression levels of IL-6 [8.35(3.45,8.99)], IL-1β [6.90(2.01,9.72)], TNF-α [12.04(3.31,14.08)], c-myc [2.21(1.80,3.04)], pSTAT3, Ki-67, and pH2AX were higher than those in the control group. The pathological changes of the esophageal mucosa were significantly more overt in the 4NQO + P. gingivalis group in terms of the foci of papillary hyperproliferation (median 2.00), diseased area (median 2.51 mm 2), the thickness of the esophageal wall (median 172.52 μm), the foci of hyperproliferation (median 1.00, P＜0.05), and mild/moderate dysplasia (median 1.00, P＜0.01). In mice of the 4NQO + P. gingivalis group, the expression levels of IL-6 [12.27(5.35,22.08)], IL-1β [13.89(10.04,15.96)], TNF-α [19.56(6.07,20.36)], IFN-γ [11.37(8.23,20.07)], c-myc [2.62(1.51,4.25)], cyclin D1 [4.52(2.68,7.83)], nuclear pSTAT3, COX-2, Ki-67, and pH2AX were significantly increased compared with the mice in the control group. In mice of the 4NQO + P. gingivalis group, the diseased area, invasive malignant foci as well as pSTAT3 and pH2AX expression were significantly blunted by celecoxib. Treatment with ABC markedly reduced the papillary hyperproliferative foci, invasive malignant foci, and pSTAT3 expression but not pH2AX. Conclusions:P. gingivalis promotes the occurrence of esophageal squamous cell carcinoma in mice by inducing an inflammatory microenvironment primed with 4NQO induced DNA damage. Clearance of P. gingivalis with ABC or anti-inflammatory intervention holds promise for prevention of esophageal squamous cell malignant pathogenesis via blockage of IL-6/STAT3 signaling and amelioration of inflammation.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Autism spectrum disorder (ASD) are a complex group of neurodevelopmental disorders. High heritability in ASD is still controversial, but epigenetics can better explain the pathogenesis of ASD and make up the lack of heritability research. This review discusses the role of epigenetic modification in ASD pathogenesis by analyzing the related research on epigenetic mechanism of ASD at home and abroad, in order to provide new treatment ideas and theoretical basis for clinical practice.

Objective:To compare the efficacy of concurrent and asynchronous radiochemotheray for early extranodal nasal natural killer/T-cell lymphoma (NKTCL).Methods:From 2007 to 2020, 278 patients with early NKTCL treated with comprehensive treatment in the Affiliated Tumor Hospital of Guizhou Medical University were recruited. According to the adjusted Nomogram-revised risk index (NRI) prognostic model, there were 49 cases in the good prognostic group without adverse prognostic factors (age>60 years old, increased serum lactate dehydrogenase (LDH), ECOG score ≥2, primary tumor invasion (PTI), Ann Arbor stage Ⅱ, and 229 cases in the poor prognostic group with any adverse prognostic factors. 145 of these cases were treated with concurrent radiochemotherapy, and 133 of them were treated with asynchronous radiochemotherapy.Results:The 5-year overall survival (OS) rate of the whole group was 71.0%, and the progression-free survival (PFS) rate was 67.6%. The 5-year OS rate in the good prognostic group was 95.6%, and 65.4% in the poor prognostic group ( P<0.001). In the poor prognostic group, the 5-year OS rates of patients with NRI=1(low-and moderate-risk group), NRI=2(moderate-and high-risk group), NRI≥3(high-risk group) were 72.1%, 61.1% and 47.7%, respectively ( P=0.007). There was no significant difference in curative effect between the concurrent and asynchronous radiochemotherapy groups. The 5-year OS rates were 70.6% and 69.8%( P=0.783), and the 5-year PFS rates were 67.6% and 65.2%( P=0.631). Further stratified analysis showed that the 5-year OS rates of patients with NRI=1 receiving concurrent and asynchronous radiochemotherapy were 73.1% and 76.5%( P=0.576), 62.6% and 69.3%( P=0.427) for those with NRI=2, and 58.1% and 42.3% for those with NRI≥3( P=0.954). Conclusions:Comprehensive treatment can significantly improve the prognosis of early NKTCL in the poor prognostic group. In the sequence of radiotherapy and chemotherapy, there is no significant difference in 5-year OS and PFS rates between concurrent and asynchronous radiochemotherapy. Sequential treatment with better tolerance can be adopted for early NKTCL with poor prognosis.

In this study,we developed a novel on-line solid phase extraction (SPE)-ultra-high-performance liquid chromatography tandem mass spectrometry (UHPLC-MS/MS)-based analytical method for simulta-neously quantifying 12 illicit drugs and metabolites (methamphetamine,amphetamine,morphine,co-deine,6-monoacetylmorphine,benzoylecgonine,3,4-methylenedioxymethamphetamine,3,4-methylenedioxyamphetamine,cocaine,ketamine,norketamine,and methcathinone) and cotinine(COT) in wastewater samples.The analysis was performed by loading 2 mL of the sample onto an Oasis hydrophilic-lipophilic balance cartridge and using a cleanup step (5％ methanol) to eliminate interference with a total run time of 13 min.The isotope-labeled internal standard method was used to quantify the target substances and correct for unavoidable losses and matrix effects during the on-line SPE process.Typical analytical characteristics used for method validation were sensitivity,linearity,precision,repeatability,recovery,and matrix effects.The limit of detection (LOD) and limit of quantification (LOQ)of each target were set at 0.20 ng/L and 0.50 ng/L,respectively.The linearity was between 0.5 ng/L and 250 ng/L,except for that of COT.The intra-and inter-day precisions were ＜10.45％ and 25.64％,respec-tively,and the relative recovery ranged from 83.74％ to 162.26％.The method was used to analyze various wastewater samples from 33 cities in China,and the results were compared with the experimental re-suits of identical samples analyzed using off-line SPE.The difference rate was between 19.91％and-20.44％,and the error range could be considered acceptable.These findings showed that on-line SPE is a suitable alternative to off-line SPE for the analysis of illicit drugs in samples.

Objective:To analyze the efficacy and prognostic factors of radiotherapy combined with asparaginase/peaspartase-based chemotherapy regimen in the treatment of early stage extranodal natural-killer/T cell lymphoma of the upper aerodigestive tract (UADT ENKTCL).Methods:267 early stage UADT ENKTCL patients were treated in Guizhou Cancer Hospital from October 2003 to February 2020. Among them, 229 patients received radiotherapy or radiotherapy combined with menpartaminase/permenidase-based chemotherapy regimen and 38 patients were treated with radiotherapy or chemotherapy alone. The overall survival (OS) and progression-free survival (PFS) were calculated by Kaplan- Meier method, log-rank test was conducted for univariate analysis and Cox regression model was performed for multivariate analysis. Results:The 5-year OS and PFS were 67.2% and 61.5% in all patients. The 5-year OS and PFS in patients treated with radiotherapy combined with chemotherapy, radiotherapy alone and chemotherapy alone were 71.7%, 35% and 49%(all P<0.001), and 66.4%, 35% and 28%(all P<0.001), respectively. According to the NRI risk stratification, 246 patients treated with radiotherapy and chemotherapy were divided into the favourable and the unfavourable prognosis groups. The 5-year OS was 93.3% and 64.3%( P<0.001) and the 5-year PFS was 91.1% and 56.7%( P<0.001) in two groups. For patients receiving radiotherapy with a dose ≥50 Gy and<50 Gy, the 5-year OS was 72.4% and 55.7%( P<0.001), and the 5-year PFS was 68.3%, and 36.5%( P<0.001). In the unfavourable prognosis group, the 5-year OS of patients receiving ≥ 4 and<4 cycles of chemotherapy was 65.5% and 59.2%( P=0.049), and the 5-year PFS was 60.7% and 50.6%( P=0.018). Univariate analysis showed that stage Ⅱ, ECOG≥2, primary tumor invasion, radiotherapy alone, NRI≥1(Nomogram-revised risk index), EBV-DNA≥2 750 copies/ml, radiotherapy dose < 50 Gy, and<4 cycles of chemotherapy were associated with unfavorable 5-year OS and PFS (all P<0.05), and CHOP-like regimen was the risk factor of unfavorable 5-year PFS ( P<0.05). Multivariate analysis demonstrated that primary tumor invasion, ECOG≥2, and radiotherapy dose <50 Gy were associated with unfavorable OS and PFS (all P<0.05), and stage Ⅱ was the risk factor of unfavorable 5-year OS ( P<0.05). Conclusions:The prognosis of early stage low-risk UADT ENKTCL of is favourable. Sufficient dose of extended involved-field radiotherapy is an important curative modality in early stage UADT ENKTCL. Compared with radiotherapy alone, radiotherapy combined with chemotherapy can significantly improve the prognosis of early stage UADT ENKTCL patients in the unfavourable prognosis group. Full-course chemotherapy can significantly prolong the long-term survival in the unfavorable prognosis group. The chemotherapy containing asparaginase can significantly enhance the prognosis of patients with early stage UADT ENKTCL.
