Objective: To construct an evaluation index system of cervical cancer prevention and control literacy, so as to provide an assessment tool for cervical cancer prevention and control literacy. Methods: The preliminary framework for cervical cancer prevention and control literacy was designed based on literature review. Twenty-one experts with both theoretical and practical experience in cervical cancer prevention and control were invited to participate in two rounds of Delphi consultation. The weights of indicators were determined by the percentage weighting method and product method, and the response rate, authority level, opinion concentration degree, and coordination degree of experts were evaluated. Results: Twenty-one experts participated in the consultation, including 3 males and 18 females. There were 11 experts with a doctor's degree, 7 with a master's degree and 3 with a bachelor's degree. All of them had senior professional titles and had more than 10 years of working experience. The recovery rates of the two rounds of consultations were 100.00% and 95.24%, the authority coefficients were 0.963 and 0.948, and Kendall's coefficients of concordance were 0.175 and 0.148 (both P<0.05), respectively. The final cervical cancer prevention and control literacy evaluation index system included 3 primary indicators (basic knowledge and concepts: 0.334; healthy lifestyle and behaviors: 0.338; basic skills: 0.328), 12 secondary indicators, with "capability to accurately acquire, comprehend, evaluate and apply health information" having the highest weight (0.166), and 51 tertiary indicators, with "HPV vaccination" (0.086), "consulting on relevant issues" (0.082), and "expressing personal perspectives" (0.080) having relatively higher weights. Conclusion The evaluation index system of cervical cancer prevention and control literacy serves as a valid assessment tool for women of appropriate age, providing the reference for developing targeted health education to enhance cervical cancer prevention and control literacy.

Objective:To evaluate the efficacy and safety of simultaneous integrated boost intensity-modulated radiation therapy (SIB-IMRT) for rectal cancer with lateral lymph node metastasis (LLNM).Methods:From January 2016 to December 2022, 103 rectal cancer patients with LLNM were enrolled. The patients were divided into SIB-IMRT group (52 cases) and conventional chemoradiotherapy (CRT) group (51 cases) using the random number table method. The dose was 50 Gy for the pelvis with 60 Gy of SIB-IMRT for the LLNM in the SIB-IMRT group. The dose was 50 Gy for the pelvis in the CRT group. The primary endpoint was the lateral recurrence rate. The efficacy and adverse reactions of the two groups were compared.Results:The adverse reactions and surgical complications after neoadjuvant radiotherapy were comparable between the two groups. The response rates of LLNM treatment were 76.9% and 56.9%, respectively, in the two groups ( χ2=4.69, P=0.03). The SIB-IMRT group and CRT group had a local recurrence rate of 7.7% and 25.5% ( χ2=5.92, P=0.015), respectively, and a lateral recurrence rate of 3.8% and 23.5% ( χ2=8.49, P=0.004), respectively. Univariate analysis showed that the SIB-IMRT, short axis of lateral lymph nodes <5 mm after radiotherapy, and negative result in the postoperative lymph node pathological examination were factors associated with lateral recurrence. Multivariable regression analysis demonstrated that the SIB-IMRT ( HR=6.42, 95% CI: 1.40-29.49) and short axis of lateral lymph nodes <5 mm after radiotherapy ( HR=0.17, 95% CI: 0.04-0.66) were independent factors associated with lateral recurrence. The two groups had a 3-year disease-free survival of 73.25% and 62.6% ( P>0.05), respectively, and a 3-year overall survival of 87% and 82.5% ( P>0.05), respectively. Conclusions:The SIB-IMRT is safe and effective for rectal cancer with LLNM. The short axis of lateral lymph nodes <5 mm after neoadjuvant radiotherapy and SIB-IMRT is an independent risk factor for lateral recurrence.

Exogenous lipoid pneumonia is an inflammatory response to the lungs caused by inhaled lipid substances, which is prone to secondary bacterial infection, resulting in the formation of local abscesses, which can be life-threatening in severe cases. This paper reports a case of a 55-year-old patient with diesel aspiration, secondary to Klebsiella pneumoniae (ESBL positive) and Candida glabrata infection resulting in lung abscess formation. He was treated with a variety of antibacterial drugs for anti-infection, non-invasive ventilator ventilation, bronchoalveolar lavage, glucocorticoids, phlegm and other medical treatments. Finally, he underwent middle lobectomy for improvement and was discharged from the hospital, and he recovered well with regular follow-up.

Objective : To analyze the risk factors for endophthalmitis requiring evisceration or enucleation. Methods : The charts of 121 eyes of 121 inpatients with endophthalmitis were retrospectively reviewed , and the group that required evisceration or enucleation (24 patients) with those that received salvaging therapies (97 patients) were compared. Age , sex , medication history , past medical history , clinical manifestation , Leukocyte counts and treatment progression were retrospectively analyzed. Results : Twenty four eyes( 19. 8% )underwent enucleation or evisceration. The proportion of corneal ulcerative endophthalmitis ( 33. 3% ) and endogenous endophthalmitis (25. 0% ) in evisceration or enucleation group was greater than that in the salvaging group ( 1. 0% , 4. 1% ) (P < 0. 001) . The group of eviscerated or enucleated eyes was older (P < 0. 05] , had poorer initial visual acuity [(2. 9 ± 0. 2) LogMAR vs (2. 3 ± 0. 5) LogMAR , P < 0. 001] , had longer duration before intervention ( 15. 8 d vs 4. 6 d , P < 0. 05) , and had more Leukocyte counts [( 12. 8 ± 5. 6) × 109/L vs (9. 1 ± 3. 3) × 109/L , P < 0. 005 ] . With Logistic regression analysis , corneal ulcer, endogenous endophthalmitis , initial vision , leukocyte counts , duration before intervention were the risk factor for evisceration or enucleation ( OR = 343. 283 , OR = 22. 608 , OR = 1 920. 384 , OR = 1. 341 , OR = 1. 167 ) . Conclusion The most common cause of evisceration or enucleation caused by infectious endophthalmitis are infections from corneal ulcer and from endogenous source. The risk factors for endophthalmitis requiring evisceration or enucleation would be considered to be corneal ulcer endophthalmitis , endogenous endophthalmitis , initial vision , leukocyte counts , and duration before intervention.

Essential tremor (ET) is a common movement disorder. It is characterized by a distinctive 4-12 Hz action tremor typically affecting bilateral upper limbs. Existing drugs for ET mainly include β-blockers, anticonvulsants, benzodiazepines, etc. However, the efficacy of existing drugs is limited. With the development of the medical research, some progress has been made in the treatment of ET. The review will explore the recent advances in the treatment of ET,such as new drugs, surgical treatment, repetitive transcranial magnetic stimulation, rehabilitation treatment, etc., in order to provide clinical application prospects.

Objective:To investigate the prognosis after salvage radiotherapy with or without hormone therapy for prostate cancer.Methods:From May 2014 to December 2020, 248 patients undergoing salvage radiotherapy due to prostate-specific antigen (PSA)persistence or biochemical progression after radical prostatectomy at Sun Yat-sen University Cancer Center (n=157) and West China Hospital, Sichuan University (n=91) were analyzed. Median age was 66 (45-78) years old. Median PSA was 23.50 (0.18-845.00) ng/ml. The number of PSA persistence and biochemical progression were 143 (59%) and 105 (42%). The number of pT 2, pT 3a, pT 3b, pT 4, and unknown T stage was 99, 49, 78, 15 and 7 cases.The number of N 0, N 1 and unknown N stage was 153, 44 and 51 cases. 165 cases had positive surgical margin. Gleason score of 6, 7, 8, >8 score and unknown was in 12, 104, 34, 90 and 8 patients. Early and late salvage radiotherapy was performed in 117 and 131 patients, and 70 patients (28%) were CRPC. Hormone therapy was used combined with radiotherapy in 182 patients (73%). PSA decline after radiotherapy was compared with Chi-squre test. Kaplan-Meier method and log-rank test were used to compare progression free-survival (PFS)after radiotherapy. Univariate and multivariate analyses of PFS were performed using Cox proportional hazards model. Early salvage radiotherapy was defined as PSA≤0.5 ng/ml before radiotherapy, and late salvage radiotherapy was defined as PSA>0.5ng/ml. Results:PSA response (PSA decline ≥50%) rate was 94% (233/248), and 82% (203/248) patients had PSA decline ≥ 90%. Twelve (5%) patients had rising PSA after completing radiotherapy, but only 4 (2%) had real progression. The median PFS was 69 months (95% CI 68-70), and 3-year and 5-year PFS rate were 80% and 67%. PFS of PSA persistence and biochemical progression were similar ( HR =0.71, 95% CI 0.37-1.37, P=0.311). Compared with late salvage radiotherapy, early salvage radiotherapy had better PFS [69 (95% CI 68-70) vs. 59 (95% CI 44-74) months, P<0.001]. Compared with hormone sensitive, castration-resistant was associated with worse PFS (5-year PFS rate 74% vs. 51%, P<0.001). In multivariate analysis, Gleason score>8, castration-resistant and late salvage radiotherapy were unfavorable prognostic factors. Conclusions:In patients receiving salvage radiotherapy with or without hormone therapy for PSA persistence and biochemical progression after radical prostatectomy, high PSA level before radiotherapy and castration resistant is associated with poor prognosis.

PURPOSE: Tripartite-motif-containing protein 56 (TRIM56) has been found to exhibit a broad antiviral activity, depending upon E3 ligase activity. Here, we attempted to evaluate the function of TRIM56 in multiple myeloma (MM) and its underlying molecular basis. MATERIALS AND METHODS: TRIM56 expression at the mRNA and protein level was measured by qRT PCR and western blot analysis. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and flow cytometry analysis was performed to investigate the effect of TRIM56 on MM cell proliferation and apoptosis. The concentrations of interferon (IFN)-β, interleukin (IL)-6, and tumor necrosis factor-α in MM cell culture supernatants were detected with respective commercial ELISA kits. Western blot was employed to determine the effect of TRIM56 on toll-like receptor 3 (TLR3)/toll-IL-1 receptor (TIR) domain-containing adaptor inducing IFN-β (TRIF) signaling pathway. RESULTS: TRIM56 expression was prominently decreased in MM cells. Poly (dA:dT)-induced TRIM56 overexpression in U266 cells suppressed proliferation, induced apoptosis, and enhanced inflammatory cytokine production, while TRIM56 knockdown improved growth, diminished apoptosis, and inhibited inflammatory cytokine secretion in RPMI8226 cells. Moreover, TRIM56 knockdown blocked TLR3 signaling pathway. Furthermore, poly (I:C), a TLR3 agonist, markedly abolished TRIM56 depletion-induced increase of proliferation, decrease of apoptosis, and reduction of inflammatory factor in MM cells. CONCLUSION: TRIM56 may act as a tumor suppressor in MM through activation of TLR3/TRIF signaling pathway, contributing to a better understanding of the molecular mechanism of TRIM56 involvement in MM pathogenesis and providing a promising therapy strategy for patients with MM.

Objective To identify if there was increased DNA damage in cardiomyocytes of rats with diabetic cardiomyopathy and also to evaluate the change in gene expression of DNA repair enzymes 8-oxoguanine DNA glycosylase 1(OGG1) and AP endonuclease 1(APE1).Methods Total DNA,RNA and proteins of hearts were isolated in diabetes rat hearts.DNA damage was examined with quantitative polymerase chain reaction(Q-PCR) assay.mRNA and protein expressions of OGG1 and APE1 were detected with real time-polymerase chain reaction(RT-qPCR) and Western blot analysis.The levels of 8-hydroxy-2′-deoxy-guanosine(8-OHdG) in DNA were studied with ELISA.ResultsThe damage of mtDNA was increased in rat hearts(P<0.05) and there was not significant damage in nDNA.The amount of 8-OHdG in DNA was significantly increased(P<0.05),mRNA and protein expressions of OGG1 and APE1 were increased in diabetic rat hearts(P<0.01).Conclusions The damage of mtDNA increased in diabetic rat hearts.Although the expression of OGG1 and APE1 increased in diabetic rat hearts,which fails to repair the damage of the mtDNA.The increased mtDNA damage may contributes to myocardium damage.

Objective: To observe the clinicopathologic features and prognosis of prostate cancer (PCa) in young men. Methods: Twenty-eight early onset (≤55 years) patients with PCa pathologically confirmed in the Peking University Third Hospital and Peking University Shougang Hospital from January 1st 2000 to August 31st 2016 were collected. There were 18 radical prostatectomy (RP) cases and 10 transrectal prostatic biopsy cases. Contemporaneously, 445 elderly (>55 years) patients were collected, of which 385 had detailed pathological information, were chosen as control group. The mean age of young group was 51 years (29-55 years). Follow-up data for 22 cases were available (1-110 months). The correlation of the clinicopathological features and prognosis were analyzed retrospectively. Results: Presurgical prostatic specific antigen (PSA) level was abnormal in young patients, with 18 cases (64.3%) had elevated fPSA level, 26 (92.9%) had increased tPSA level, and 26 (92.9%) had decreased fPSA/tPSA ratio. Gleason score (GS) was 8 in 10.7% (3/28) of cases, and 9 in 42.9% (12/28) of cases. Of the 18 patients with RP, 17 (94.4%) had pT stage ≥pT2c. PSA level (P=0.006) and GS (P=0.001) were positively correlated with pT stage. Family history of PCa in 1st degree relatives was found in 9.1% of the cases. During follow-up, 2 patients died of PCa, 7 patients showed progression within 24 months. There were no significant differences in PSA level and GS between young patients and elderly patients, while the former group was more likely to have incontinence (P=0.023), higher PSA levels (P=0.001), and lower overall survival (P=0.049). Only postsurgical PSA level was found to be negatively associated with overall survival (P=0.030) and cancer specific survival (P=0.021) in young patients. Conclusions Presurgical PSA level and GS are positively correlated with pT stage of early onset PCa. Compared with elderly patients, young patients are more likely to have incontinence, higher postsurgical PSA level, and lower overall survival. Among all the parameters, only postsurgical PSA level shows an adverse impact on prognosis of early onset PCa. Young patients, especially those with family history, may benefit from studies on the susceptibility loci and phenotype of PCa.
