Objective To analyze the burden and changing trend of testicular cancer in China from 1990 to 2019.Methods Based on the 2019 Global Burden of Disease Database(GBD 2019),analyze the incidence,mortality,disability-adjusted life years(DALYs),years of life lost(YLLs),years lived with disability(YLDs)and their variation trend of testicular cancer in Chinese population from 1990 to 2019.Evaluating changes in age standardized rate(ASR)by calculating annual estimated percentage change(EAPC).According to the age grouping,analyze the age distribution characteristics of testicular cancer disease burden by age group.Results In 2019,the incident cases,deaths,age-standardized incidence rate,and age-standardized mortality rate of testicular cancer in China were 17.17×103,1.21×103,2.39/105,and 0.16/105,respectively.Compared to 1990,incident cases,deaths,and age-standardized incidence rate increased obviously in China,which was consistent with the global change trend,while the increase was higher than the global level.However,both Chinese and global age-standardized mortality rate showed a downward trend.From 1990 to 2019,DALYs,YLLs and YLDs of testicular cancer increased by 29.66%,9.83%and 720.91%respectively in China.The two age groups,0-15 years group and 30-35 years group,were with highest incidence of testicular cancer,while the highest disease burden of testicular cancer was 30-35 years.Conclusion From 1990 to 2019,the disease burden of testicular cancer in China showed an upward trend.Adolescents and young adults should be the priority population for screening and prevention due to their higher incidence and disease burden.

Two undescribed terpene glycosides and two compounds were isolated from the n-butanol fraction of Alpiniae Oxyphyllae Fructus by using various chromatographic methods, including MCI Gel, Sephadex LH-20, ODS, silica gel and semi-preparative HPLC. The structures of the isolated compounds were identified by spectroscopy methods (1D, 2D NMR, UV, IR, MS, etc.), and the absolute configuration of the compound 1 was determined by ECD calculation and acid hydrolysis. Compounds 1 and 2 are new compound, and compounds 3 and 4 were isolated from Alpiniae Oxyphyllae Fructus for the first time.

Aim To explore the potential mechanism of Dangshen Pingfei Huoxue decoction (DPHD) in the treatment of pulmonary fibrosis. Methods The common targets of DPHD and pulmonary fibrosis were obtained. Cytoscape software was used to construct " disease-drug-ingredients-targets " network diagram, and the common targets were imported into the STRING database for protein-protein interaction (PPI) analysis to screen out the core targets. In order to screen out key signaling pathways, the core genes were inputted into the DAVID platform for gene ontology (GO) and kyoto encyclopedia of genes genomes (KEGG) enrichment analysis. Then the molecular docking technology was used to verify the molecular docking between the core components and the key proteins in the signaling pathway. Finally, the molecular docking technology was used to verify the results of network pharmacology. Results A total of 176 active ingredients were obtained, and the top 5 was quercetin, kaempferol, luteolin, naringenin and p-sitosterol, respectively. A total of 116 common targets were obtained. A total of 21 core targets were finally obtained by PPI screening, and the top 5 was AKT1, CCND1, CASP3, MYC and IL1B, respectively. The results of GO enrichment analysis showed that DPHD was mainly involved biological processes of oxidative stress, proliferation and differentiation, transcriptional regulation, drug response and inflammatory response. The results of KEGG enrichment analysis indicated that the mainly signaling pathways included PI3K/Akt, MAPK, cellular senescence, AMPK, and TGF-beta. Molecular docking results showed that the binding energies of the top 5 active components of DPHD and the top 5 core targets were all less than-6.0 kcal • mo

Objective:To investigate the efficacy and safety of promestriene vaginal gelatin capsules administered through different schemes in the treatment of postmenopausal female urethral syndrome.Methods:A total of 120 patients with postmenopausal female urethral syndrome who received treatment in General Hospital of Medical and Health Group of Cixi Third People's Hospital from January 2021 to June 2022 were included in this study. They were randomly divided into groups A and B ( n = 60/group). Group A was treated with vaginal gelatin capsules containing 10 mg promestriene once a day. Group B was treated with vaginal gelatin capsules containing 10 mg promestriene twice a day. Both groups were treated for 20 days as a course of treatment. The improvement of symptoms, lower urinary tract symptom score, quality of life score, estradiol level, follicle stimulating hormone level, and endometrial thickness were compared between the two groups. Results:After treatment, the scores of incomplete urination, urination interval, intermittent urination, dysuria, thinner urine line, urination force, and nocturnal urination times in group A were (2.51 ± 1.76) points, (2.66 ± 1.08) points, (2.61 ± 1.45) points, (2.48 ± 1.42) points, (2.85 ± 1.03) points, (2.48 ± 1.42) points, and (2.52 ± 1.72) points, respectively, which were significantly lower than (3.15 ± 1.35) points, (3.23 ± 1.14) points, (2.99 ± 1.57) points, (3.08 ± 1.09) points, (3.45 ± 1.72) points, (3.25 ± 1.08) points, and (3.21 ± 1.87) points, respectively, in group B ( t = 10.57, 9.78, 13.83, 10.34, 9.35, 12.34, 9.45, all P < 0.05). The quality of life score in group A was (2.45 ± 0.86) points, which was significantly lower than (3.51 ± 0.92) points in group B ( t = 5.45, P < 0.05). There were no significant differences in estradiol and follicle stimulating hormone levels and endometrial thickness between the two groups before and after treatment (all P > 0.05). There was no significant difference in the incidence of adverse reactions between the two groups. Conclusion:Local application of promestriene vaginal gelatin capsules can improve the urethral syndrome in postmenopausal women. The once daily 10 mg promestriene vaginal gelatin capsule administration scheme can achieve better efficacy and safety than the twice daily administration scheme. The study is innovative, scientific, and worthy of clinical promotion.

Disturbance of macrophage-associated lipid metabolism plays a key role in atherosclerosis. Crosstalk between autophagy deficiency and inflammation response in foam cells (FCs) through epigenetic regulation is still poorly understood. Here, we demonstrate that in macrophages, oxidized low-density lipoprotein (ox-LDL) leads to abnormal crosstalk between autophagy and inflammation, thereby causing aberrant lipid metabolism mediated through a dysfunctional transcription factor EB (TFEB)-P300-bromodomain-containing protein 4 (BRD4) axis. ox-LDL led to macrophage autophagy deficiency along with TFEB cytoplasmic accumulation and increased reactive oxygen species generation. This activated P300 promoted BRD4 binding on the promoter regions of inflammatory genes, consequently contributing to inflammation with atherogenesis. Particularly, ox-LDL activated BRD4-dependent super-enhancer associated with liquid-liquid phase separation (LLPS) on the regulatory regions of inflammatory genes. Curcumin (Cur) prominently restored FCs autophagy by promoting TFEB nuclear translocation, optimizing lipid catabolism, and reducing inflammation. The consequences of P300 and BRD4 on super-enhancer formation and inflammatory response in FCs could be prevented by Cur. Furthermore, the anti-atherogenesis effect of Cur was inhibited by macrophage-specific Brd4 overexpression or Tfeb knock-out in Apoe knock-out mice via bone marrow transplantation. The findings identify a novel TFEB-P300-BRD4 axis and establish a new epigenetic paradigm by which Cur regulates autophagy, inhibits inflammation, and decreases lipid content.

ObjectiveTo explore the effect of Gegen Qinliantang （GQL） on vulnerable plaque of atherosclerosis based on the macrophage pyroptosis mediated by nuclear factor （NF）-κB/NOD-like receptor protein 3 （NLRP3）/cysteine-aspartic acid protease （Caspase）-1 pathway. MethodA total of 12 normal C57BL/6CNC mice were used as the control group， and 60 ApoE^-/- mice of the same line were randomized into 5 groups： model group， low-dose， medium-dose， and high-dose GQL groups （GQL-D， GQL-Z， GQL-G groups， respectively）， and western medicine group. The control group and model group were given （ig） equal volume sterile distilled， and GQL-D， GQL-Z， GQL-G and western medicine groups received （ig） corresponding concentration of drugs for 8 weeks. Aortic plaques were observed based on hematoxylin and eosin （HE） staining. Serum levels of interleukin （IL）-1β and IL-18 were detected by enzyme-linked immunosorbent assay （ELISA）， protein levels of macrophage mannose receptor （CD206）/apoptosis-associated speck-like protein containing a CARD （ASC） and CD206/NLRP3 by double-labeling immunofluorescence， and C-terminal gasdermin D （GSDMD）， N-terminal GSDMD， NLRP3， pro-cysteinyl aspartate specific proteinase 1 （pro-Caspase-1） and NF-κB p65 by Western blot. ResultCompared with the control group， model group demonstrated serious pathological changes， rise of the levels of serum IL-1β and IL-18 and tissue ASC， NLRP3， C-terminal GSDMD， N-terminal GSDMD， pro-Caspase-1， and NF-κB p65， and decrease of CD206 level （P<0.05）. As compared with model group， the administration groups showed alleviation of the lesions in aortic wall， decrease in levels of serum IL-1β and IL-18 and tissue ASC， NLRP3， C-terminal GSDMD， N-terminal GSDMD， pro-Caspase-1， and NF-κB p65， and rise of CD206 level， with significant difference between some groups （P<0.05）. ConclusionGegen Qinliantang alleviates vulnerable plaque of atherosclerosis by regulating NF-κB/NLRP3/Caspase-1 pathway and further relieving macrophage pyroptosis.

We performed this study to investigate pathological upgrading from biopsy to prostatectomy and clinicopathological factors associated with grade group (GG) upgrading in patients with International Society of Urological Pathology (ISUP) GG 1 and 2 prostate cancer (PCa) in a Chinese cohort. We included patients diagnosed with PCa with ISUP GG 1 and 2 at biopsy, who underwent RP at our institution. Pre- and postoperative clinical variables were examined. Univariate and multivariate logistic regression analyses were conducted to identify independent factors associated with GG upgrading. Patients in GG upgraded group had higher total prostate-specific antigen (tPSA; median: 14.43 ng ml^-1 vs 10.52 ng ml^-1, P = 0.001) and PSA density (PSAD; median: 0.45 ng ml^-2 vs 0.27 ng ml^-2, P < 0.001) than those in GG nonupgraded group. Patients in upgraded group had a higher ratio for Prostate Imaging-Reporting and Data System (PI-RADS) score >3 (86.4% vs 67.9%, P < 0.001). Those with GG 1 in biopsy were more likely to experience GG upgrading after RP than those with GG 2 (71 vs 54, P = 0.016). Independent preoperative factors predicting GG upgrading were PI-RADS score >3 (odds ratio [OR]: 2.471, 95% confidence interval [CI]: 1.132-5.393; P = 0.023), higher PSAD (P = 0.001), and GG in biopsy (OR: 0.241, 95% CI: 0.123-0.471; P < 0.001). The histopathological analyses of RP specimens revealed that perineural invasion (PNI; OR: 1.839, 95% CI: 1.027-3.490; P = 0.041) was identified as an independent factor associated with GG upgrading. Our results revealed that GG in the biopsy, PSAD, PI-RADS score >3, and PNI were independent factors of GG upgrading. These factors should be considered for patients with ISUP grade ≤2 PCa.

Objective: To examine the prevalence and trend of tobacco and e-cigarettes uses and identify the influencing factors for smoking behavior in junior middle school students in Shanghai, and provide data support and scientific basis for the development of tobacco control intervention strategy in adolescents. Methods: Multi-stage stratified random sampling method was used to select junior middle school students in 8 districts and 10 districts in Shanghai in 2013 and in 2019 respectively. Information about tobacco and e-cigarettes uses in the students were collected by using self-administrated questionnaire. The prevalence of tobacco and e-cigarettes uses were calculated, the difference between two years was compared with χ² test. The influencing factors were identified by multivariate logistic regression analysis. Results: In 2019, the current smoking rate was 0.6% in junior middle school students in Shanghai, and the smoking attempt rate was 2.9%, both were lower than the levels in 2013 (0.7% and 6.9%). The current use rate of e-cigarettes was 0.6% in 2019,with no significant change compared with 2013 (0.6%). The proportion of the students who had heard of e-cigarettes in 2019 (78.4%) was higher than that in 2013 (47.2%). In 2019, the second-hand smoke (SHS) exposure rate at home, in both indoor and outdoor public places and on public transportations was 72.5%, which was slightly lower than the level in 2013 (73.0%), the differences were all significant (P<0.05). In 2019, the students seeing close friend smoking (OR=27.381, 95%CI: 12.037-62.287), seeing someone smoking in school (OR=2.477, 95%CI: 1.155-5.312), believing that SHS may not be harmful (OR=8.471, 95%CI: 1.464-49.005) had higher possibility of smoking. Being aged ≥15 years (compared with being aged ≤12 years, OR=8.688, 95%CI: 1.922-39.266), exposure to SHS in outdoor public place (OR=8.608, 95%CI: 1.048-70.692), close friend smoking (OR=8.115, 95%CI: 1.754-37.545) were positively associated with e-cigarettes use, and believing that smoking results in uncomfortable social contact [compared with believing that smoking results in comfortable social contact (OR=0.105,95%CI: 0.018-0.615)] were negatively associated with e-cigarettes use, the difference was significant (P<0.05). Conclusion: The prevalence of tobacco and e-cigarette uses in junior middle school students in Shanghai remained at a low level in recent years. The SHS exposure rate in junior middle school students is high. Smoking behavior of junior middle school students is closely related to personal attitude and awareness of tobacco, exposure to SHS, peer smoking and the situation of tobacco control in schools. Prevention and intervention should be carried out from multi-dimensions to effectively protect teenagers from tobacco hazards.

Aim To explore the roles of miRNA-132 and its related proteins(Mecp2, CREB)in the mechanism of methamphetamine(MA)-induced neurotoxicity and dependence.Methods The rats were intraperitioneally injected(ip)with MA(10 mg·kg-1·d-1)to establish methamphetamine dependence model with different dependent time courses of 1 week, 2 weeks, and 4 weeks respectively.The miRNA-132 and Mecp2 mRNA were detected by RT-qPCR, and the Mecp2, p-Mecp2, CREB and p-CREB proteins were detected by Western blot in the tissues of frontal cortex and hippocampus.Results In the frontal cortex, the miRNA-132 and Mecp2 mRNA were up-regulated in MA-dependent groups(P<0.05 and P<0.01), while the Mecp2 protein were down-regulated(P<0.01).MA could promote the phosphorylation of Mecp2 protein in the frontal cortex(P<0.01).In hippocampus, the miRNA-132 was down-regulated in the MA-dependent groups, but Mecp2 mRNA was up-regulated(P<0.05).Mecp2 protein increased in MA-dependent 1 week group(P<0.05), and then recovered with the prolonged time of MA dependence, then decreased in MA-dependent 4 weeks groups(P<0.05)in hippocampus.The phosphorylation level of Mecp2 was significantly decreased in the 1 week group(P<0.01), and then increased in the 2 weeks group(P<0.01)in hippocampus.Conclusions MA could induce an abnormal expression of miRNA-132 in the frontal cortex and hippocampus, and miRNA-132 might inhibit the translation of Mecp2 mRNA and induce the decrease expression of Mecp2 protein in the frontal cortex.But in hippocampus, miRNA-132 does not show the correlation with the Mecp2 expression trend of the frontal cortex.And miRNA-132 regulation does not depend on the expression of Mecp2 in hippocampus.
