Objective To study the occurrence of tinnitus in elderly population in the Chengqiao area of Chongming Island,Shanghai,and explore the influencing factors,so as to provide reference for prevention and treatment of tinnitus in special areas.Methods A combination of questionnaire surveys,scale assessments,and pure-tone audiometry test were employed in this study.The study involved 6 358 elderly individuals who underwent health examinations at the Chengqiao Town Community Health Service Center in Chongming,Shanghai,from June 2019 to December 2021.Single and multiple factor analysis methods were used to analyze the impact of 13 factors,including gender,age,hearing status,sleep quality,anxiety and depression status,history of alcohol consumption,smoking history,history of noise exposure,history of ototoxic drug use,hypertension,diabetes,hyperlipidemia,and coronary heart disease on tinnitus in the elderly population.Results ① Among the 6 358 elderly cases,there were 2 110 cases with tinnitus,and the incidence rate of tinnitus was 33.2％(2 110/6 358),and 1 712 cases were chronic tinnitus(81.1％),and 1 156 cases were bilateral tinnitus(54.8％).According to THI score,there were 1 012 patients(48％)were mild tinnitus,and 2 030 patients(96.2％)with average hearing threshold ≥25 dB HL.② Univariate analysis showed that age,hearing status,sleep quality,anxiety and depression,history of noise expo-sure,history of ototoxic drugs,and history of hypertension were related to the occurrence of tinnitus.Further bina-ry logistic regression analysis showed that increasing age(OR=1.10,95％CI 1.09～1.11,P＜0.001),hearing loss(OR=5.56,95％CI 4.31～7.18,P＜0.001),sleep disorder(OR=3.32,95％CI 2.82～3.91,P＜0.001),anxiety depression(OR=2.02,95％CI 1.71～2.39,P＜0.001),history of noise exposure(OR=3.67,95％CI 3.20～4.21,P＜0.001),history of ototoxic drugs(OR=2.20,95％CI 1.84～2.64,P＜0.001)and history of hy-pertension(OR=1.73,95％CI 1.53～1.95,P＜0.001)increased the risk of tinnitus.Conclusion The incidence of tinnitus in the elderly people in the Chengqiao area of Chongming is relatively high.Factors such as age,hearing status,sleep quality,anxiety and depression,history of noise exposure,history of ototoxic drugs,and history of hypertension are risk factors for the occurrence of tinnitus in the elderly population.

During the progression of heart failure(HF),abnormal transduction of the transforming growth factor-β(TGF-β)/Smads signaling pathway is important mechanism of myocardial fibrosis(MF)in HF.TGF-β,a key factor in MF,is in an overexpression state in the process of MF in HF,and Smads is a major effector downstream of TGF-β.The TGF-β/Smads pathway induces abnormal proliferation of myofibroblasts,aggravates myocardial extracellular matrix deposition,and reduces the ability of the cardiac tissues to resist fibrosis,which plays a complex role in the pathogenesis of MF in HF.Traditional Chinese medicine(TCM)has the efficacy of unequivocal inhibiting myocardial collagen deposition,anti-MF,protecting the myocardium and improving cardiac function in the prevention and treatment of MF in HF and so on,and the TGF-β/Smads pathway is one of the key pathways through which TCM monomers,TCM combinations,and proprietary medicines can exert their cardioprotective effects on the HF.This paper reviews the existing experimental research results of TCM intervening in the TGF-β/Smads pathway for the treatment of MF in HF over the past 10 years,with a view to providing theoretical basis for the prevention and treatment of HF MF well as the development and of new drugs.

Objective:To explore the incidence of sudden deafness accompanied with tinnitus, the selection of examination protocols and treatment, and to provide reference for the establishment of new guidelines for sudden deafness.Methods:CiteSpace software was used for analysis and data mining to analyze and summarize the computer-retrieved articles on diagnostic examination and treatment of sudden deafness accompanied with tinnitus collected from CNIC, Wanfang and Web of Science databases from 2011 to 2021.Results:A total of 207 randomized controlled studies were retrieved in this study, including 121 in Chinese and 86 in English. Finally, 74 Chinese literatures and 16 English literatures were included. Among the 74 valid Chinese literatures, 64 (86.5%) were accompanied with tinnitus, 58 (78.4%) with dizziness/vertigo, 25 (33.8%) with aural fullness, 10 (13.5%) with headache, 4 (5.4%) with insomnia, 4 (5.4%) with a mixture of dizziness and tinnitus, and 2 (2.7%) with vomiting. Among the 16 English literatures, 15 (93.8%) were accompanied with tinnitus, 12 (75.0%) with vertigo, 1 (6.3%) with aural fullness, and 1 (6.3%) with a mixture of various symptoms. Among the 64 Chinese articles mentioning tinnitus, only 9 mentioned tinnitus matching tests, and 1 mentioned that the treatment for tinnitus accompanying symptoms was sound therapy and psychological counseling. The incidence rates of tinnitus accompanying four different types of sudden deafness, from low to high, are as follows: low-to-mid frequency, 82.4%; mid-to-high frequency, 90.7%; complete deafness, 92.4%; and flat type, 92.8%.Conclusion:Tinnitus is the most common accompanying symptom of sudden deafness, and tinnitus matching test is an effective evaluation method. When establishing a scientific, comprehensive, and systematic diagnosis and treatment system or guidelines for sudden deafness, attention should be paid to the diagnosis and treatment of tinnitus symptoms and their adverse psychological reactions, in order to reduce the incidence of tinnitus patients in the later stage of recovery from sudden deafness.

Objective:To investigate the application value of the maximum standardized uptake value (SUVmax) of 18F prostate-specific membrane antigen (PSMA) PET/CT combined with the minimum apparent diffusion coefficient (ADCmin) of biparametric magnetic resonance imaging (bpMRI) in predicting pathological upgrading after radical prostatectomy (RP) for prostate cancer. Methods:The data of 89 patients with localized prostate cancer treated at Beijing Hospital from April 2019 to October 2023 were retrospectively analysed. The average age of patients was (68.4±7.0) years old, with prostate-specific antigen (PSA) level of 7.7 (5.4, 12.9) ng/ml, prostate volume of 34.6 (26.9, 47.1) ml, tumor diameter of 1.3 (1.0, 1.8) cm, prostate imaging reporting and data system(PI-RADS) score of 5 in 29 cases (32.6%), clinical stage ≥T 3 in 13 cases (14.6%). There were 31 cases (34.8%) in group 1 of targeted biopsy International Society of Urological Pathology (ISUP)grading groups, 36 cases (40.4%) in group 2, 11 cases (12.4%) in group 3, and 11 cases (12.4%) in group 4. All patients underwent 18F-PSMA PET/CT and bpMRI examinations before RP. The index lesion, identified as the highest Gleason score in pathological whole-mount sections, were outlined. SUVmax and ADCmin values were calculated from the images' region of interest. Pathological upgrading was defined as the post-RP grade group higher than the targeted-biopsy grade group. Clinical data of patients with and without pathological upgrading were compared. Spearman correlation coefficient analysis was used to assess the correlation between SUVmax and ADCmin. Multivariate logistic regression analysis was conducted to evaluate the factors influencing pathological upgrading. Receiver operating characteristic (ROC) curve analysis was employed to assess the predictive value of each indicator for pathological upgrading. Results:Among the 89 cases, 31 cases (34.8%) experienced pathological upgrading. Compared with the patients without pathological upgrading, the SUVmax [11.3 (8.1, 16.4) vs. 6.7 (4.6, 9.2)], SUVmax/ADCmin ratio [3.1 (2.0, 4.6) vs. 1.4 (0.9, 2.1)], PSA [9.8 (6.3, 15.6) ng/ml vs. 7.1 (5.1, 10.5) ng/ml], PSA density [0.3 (0.2, 0.5) ng/ml 2 vs. 0.2 (0.1, 0.3) ng/ml 2], and post-RP ISUP grade group [≥3 group 17 cases (54.8%) vs. 13 cases(22.4%) ]were higher in patients with pathological upgrading, while ADCmin [3.8 (3.0, 5.3) ×10 -4 mm 2/s vs. 5.2 (3.6, 6.1)×10 -4 mm 2/s] and targeted biopsy ISUP grade group [≤2 group 27 cases(87.1%) vs. 40 cases(69.0%) ] were lower (all P<0.05). Spearman analysis showed a negative correlation between SUVmax and ADCmin ( R = -0.227, P = 0.032). Multivariate logistic regression analysis revealed that SUVmax ( OR = 1.108, 95% CI 1.020-1.238), ADCmin ( OR=0.607, 95% CI 0.390-0.874), and SUVmax/ADCmin ratio ( OR = 1.815, 95% CI 1.282-2.949) independently predicted pathological upgrading. The AUC of the SUVmax/ADCmin ratio for predicting pathological upgrading (AUC = 0.817) was higher than that of SUVmax (AUC = 0.774) and ADCmin (AUC=0.686), indicating a higher predictive efficiency. Conclusions:SUVmax, ADCmin, and SUVmax/ADCmin ratio can independently predict pathological upgrading in targeted biopsy of prostate cancer. The SUVmax/ADCmin ratio has a stronger predictive value for pathological upgrading.

Objective:To explore the relation of the radiochemical purity and in vivo imaging effect of 68Ga-1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid (DOTA)- D-phe1-Tyr3-Thr8-octreotide (TATE) injection. Methods:High performance liquid chromatography (HPLC) and thin-layer chromatography (TLC) methods were established to determine 68Ga-DOTATATE, 68Ga 3+ , 68Ga in colloidal form and 68Ga-DOTA- D-Phe1-Tyr3-Thr8-dethreonine-octreotide (heptapeptide) and to study the influence of precursor purity on radiochemical purity of labelled products. The uptake of 68Ga-DOTATATE injection with different radiochemical purities was investigated in nude mice bearing AR42J cells by microPET imaging and the tumor target/non-target (T/NT) value was calculated. One-way analysis of variance and Pearson correlation analysis were used to analyze the data. Results:The contents of 68Ga 3+ and 68Ga in colloidal form were not related with precursor purity ( r values: 0.385, 0.497, P values: 0.306, 0.137), while the content of 68Ga-DOTA-heptapeptide was positively related with the purity of DOTA-heptapeptide ( r=0.957, P<0.001). The radiochemical purities of 68Ga-DOTATATE injection were (87.0±2.3)%, (86.8±0.8)% and (94.0±3.1)% when the DOTATATE purities were 90.9%, 91.6% and 99.2%, respectively. The results of microPET imaging showed that the tumor uptake was positively related with the radiochemical purity of 68Ga-DOTATATE injection ( r=0.828, P<0.001), and the T/NT values of 68Ga-DOTATATE injection with radiochemical purities of 95.7%, 85.8%, 84.5% and 79.9% were 21.25±8.84, 8.50±1.51, 11.38±1.65 and 6.01±0.99, respectively ( F=11.48, P=0.001). Conclusion:The radiochemical purity of 68Ga-DOTATATE injection is impacted by the purity of labelled precursor and manufacturing processes and is related with the imaging effect in vivo.

ObjectiveIn order to explore the changes of chemical constituents in Plantaginis Semen before and after stir-frying， ultra-high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry （UPLC-Q-TOF/MS^E） was used to rapidly identify and semi-quantitatively analyze the differential components in Plantaginis Semen processed at different stir-frying time. MethodWaters ACQUITY UPLC BEH C₁₈ column （2.1 mm×100 mm， 1.8 μm） was employed with the mobile phase of 0.1% formic acid aqueous solution （A）-acetonitrile （B） for gradient elution （0-1 min， 5%-10%B； 1-2 min， 10%-15%B； 2-10 min， 15%-20%B； 10-12 min， 20%-40%B； 12-13 min， 40%-100%B； 13-14 min， 100%-5%B； 14-15 min， 5%B）， the flow rate was 0.3 mL·min^-1， the column temperature was 40 ℃， and the injection volume was 3 μL. Electrospray ionization （ESI） was applied for mass spectrometric analysis under positive and negative ion modes， and the scanning range was m/z 50-1 500. MarkerLynx 4.1 software was used to find the differential compounds， and the intensity of each ion peak in samples with different stir-frying time was compared to study the content variations of these compounds. ResultA total of 20 components with potential significant differences were found， among which 17 were identified and 3 were unknown， mainly including phenylethanoid glycosides， iridoid glycosides， alkaloids and others. After processing， the peak intensities of 7 compounds， such as sucrose， geniposidic acid， verbascoside and plantagoguanidinic acid A， in Plantaginis Semen decreased. The peak intensities of orobanchoside， dianthoside and plantain D increased first and then decreased during the stir-frying process. The peak intensities of 10 compounds （decaffeoylacteoside， calceolarioside A， isoacteoside， etc.） increased， and 9 of them were newly generated components. ConclusionThe content and composition of the chemical components in Plantaginis Semen changed significantly after stir-frying， which may be related to the reduction of laxative effect and the enhancement of antidiarrheal and diuretic activities of Plantaginis Semen after stir-frying.
