Objective:To explore the effects of the fat mass and obesity-associated gene(FTO)on apoptosis and the inflammatory response of chondrocytes in osteoarthritis(OA).Methods:Differences in FTO expression between normal human cartilage tissue samples and OA cartilage tissue samples were examined.Primary OA chondrocytes were isolated and cultured, and a rat OA model was constructed.The expression of FTO was detected in clinical, animal and cellular samples.Cells were treated with an FTO knockdown lentivirus vector(sh-FTO)and an m 6A methylation inhibitor(cycloleucine). The amount of m 6A and the expression levels of inflammatory cytokines, interleukin-6(IL-6)and tumor necrosis factor-α(TNF-α), were detected.Flow cytometry was used to detect apoptosis in OA chondrocytes, and Western blot was used to detect the expression levels of B-cell lymphoma 2(Bcl-2)and Bcl-2-associated X protein(Bax). Results:Compared with the normal control group, FTO mRNA and protein expression in human OA cartilage tissue, rat OA cartilage tissue and OA chondrocytes was significantly increased(all P<0.05). After FTO knockdown, the level of m 6A increased, the levels of IL-6 and TNF-α decreased considerably, the apoptosis rate decreased, the expression of the proapoptotic protein Bax decreased considerably, and the expression of Bcl-2 increased considerably in primary OA chondrocytes.However, cycloleucine intervention clearly reduced the level of m6A, increased the levels of IL-6 and TNF-α, promoted cell apoptosis and the expression of apoptosis-related proteins, and reversed the effect induced by the FTO knockdown lentivirus in OA chondrocytes(all P<0.05). Conclusions:FTO may be involved in mechanisms related to the action of m 6A to promote OA chondrocyte apoptosis and the inflammatory response, thus accelerating the progression of OA.

ObjectiveTo investigate the measurement invariance and the score distribution characters of the 9-item Patient Health Questionnaire (PHQ-9), and to test its feasibility in comparing depression among adolescents of different sexes and ages. MethodsFrom September 2018 to May 2019, 12 241 adolescents aged 10 to 19 years old across 22 primary and secondary schools in Hangzhou were included based on cluster sampling method, and they were investigated by PHQ-9. The measurement invariance was tested by multi-group confirmatory factor analysis. Poisson regression analysis and Logistic regression analysis were adopted to explore the score distribution of PHQ-9 by sex and age. ResultsThe configural, metric, scalar and strict invariances (χ2=2 492.527, df=79, P<0.01, RMSEA=0.071, SRMR=0.031, CFI=0.942, TLI=0.947, ΔCFI=0.004, ΔTLI=0.002 compared with the scalar model) of PHQ-9 across sex were all acceptable, and the configural, metric and scalar invariances (χ2=3 311.991, df=414, P<0.01, RMSEA=0.076, SRMR=0.055, CFI=0.928, TLI=0.937, ΔCFI=0.010, ΔTLI=0.002 compared with the metric model) across age were acceptable. The detection rate of mild depressive symptoms in girls was higher than that in boys (52.99% vs. 46.65%, χ2=48.344, P<0.01). The PHQ-9 total scores of girls aged 13 to 17 were higher than those of boys (D=0.092~0.144, P<0.01). There was an interaction between sex and age (χ2=32.800, df=1, P<0.01, OR=0.895). Except low self-evaluation and suicide or self-injury, the detection rate of assessed symptom on each item of girls was higher than that of boys (P<0.05). ConclusionIt is discovered that PHQ-9 has measurement equivalence across sex and age in adolescents, and girls and older adolescents scored higher in PHQ-9.

Objective:To access the clinical value and related risk factors of aortic arch calcification (AoAC) in patients with renal secondary hyperparathyroidism (SHPT) on CT during parathyroid SPECT/CT imaging.Methods:From January 2014 to May 2021, 136 renal SHPT patients (70 males, 66 females, age (50.1±11.4) years) who underwent parathyroid 99Tc m-methoxyisobutylisonitrile (MIBI) SPECT/CT in Affiliated Jiangyin Hospital of Nantong University were retrospectively enrolled. AoAC score was estimated with CT(1-5), and patients were divided into none-light AoAC group (AoAC score<3) and moderate-severe AoAC group (AoAC score≥3). Independent-sample t test or Mann-Whitney U test was used to compare differences of various indicators between two groups. Univariate binary logistic regression was used to analyze the influencing factors of AoAC. Results:Of 136 renal SHPT patients, 111(81.62%) were AoAC detected by CT. There were 84 patients in none-light AoAC group and 52 patients in moderate-severe AoAC group. The age ((46.7±9.8) vs (55.7±11.6) years; t=-4.84, P<0.001), pulse pressure (52(41, 64) vs 60(51, 70) mmHg (1 mmHg=0.133 kPa); z=-3.27, P=0.001), serum corrected calcium (2.41(2.28, 2.53) vs (2.49±0.22) mmol/L; z=-2.50, P=0.013), serum phosphorus ((1.95±0.39) vs (2.14±0.48) mmol/L; t=-2.54, P=0.012), calcium phosphorus product ((4.68±1.07) vs (5.29±1.10) mmol 2/L 2;t=-3.21, P=0.013) and parathyroid hormone (PTH) level (106.30(90.15, 127.45) vs 109.90(87.93, 157.63) pmol/L; z=-2.09, P=0.036) between non-light AoAC group and moderate-severe AoAC group were significantly different. Logistic regression analysis showed that serum phosphorus (odds ratio ( OR)=7.261, 95% CI: 2.416-21.819, P<0.001), calcium and phosphorus product ( OR=1.598, 95% CI: 1.073-2.380, P=0.021) and PTH level ( OR=1.018, 95% CI: 1.007-1.029, P=0.001) were independent risk factors of AoAC. Conclusions:Hybrid SPECT/CT can be used for an effective method of evaluating AoAC in patients with renal SHPT. High serum phosphorus, high calcium phosphorus product and high PTH level may be independent risk factors of AoAC.

Chinese Journal of School Health 2022;43(10):1565-1569
Objective:
To investigate the refractive status of children and adolescents aged 4-18 years in Chengdu, and to analyze the epidemiological characteristics of refractive parameters.
Methods:
A cross sectional survey was conducted among 82 024 children and adolescents aged 4-18 years in Gaoxin District of Chengdu from August to September 2021. The prevalence of screening myopia, low vision rate, high myopia rate, refractive status and axial development were analyzed.
Results:
The prevalence of screening myopia in students aged 4-18 years was 40.42%(33 158/82 024). Low myopia was 24.51%(20 108/82 024), moderate myopia was 13.05%(10 703/82 024) and high myopia was 2.86%(2 347/82 024). The prevalence of screening myopia was 1.81% (233/12 848) in kindergarten, 34.44%(17 095/49 644) in primary school, 79.73%(9 738/12 214) in junior high school and 83.25% (6 092/7 318) in senior high school. The rate of visual impairment increased by year from the age of 4, and the rate of myopia increased most rapidly from 6 to 15 years old, the prevalenct of high myopia was compared between adjacent age groups: there were statistical differences between 9-15 years old were more likely to be nearsighted than boys( P <0.035 7). Significant differences in screening myopia between 5- and 7-17 year old groups,and in boys and girls.The median total diopter was 0.40 D at the age of 4 and developed to -2.90 D at the age of 18 . The diopter of girls aged 8-15 years was higher than that of boys, and there was statistical significance( Z=-2.53, -4.09, -5.67, -8.64, -5.56, -4.97, -2.52, -2.14, P <0.05). The axial length gradually increased with age, with the mean value of (22.31±0.59) mm at 4 years old and (24.91±1.00) mm at 18 years old. The mean corneal curvature did not change with age (43.19±1.47)D.
Conclusion
6-15 years old is a especially critical period for myopia development. More efforts need to be taken to decrease the prevalence of myopia before 6 years old. Prevention of the development of high myopia should start before the age of 10. The prevalence of myopia in girls is higher than that in boys, more prevention and control of myopia should focus on girls.

Objective:To investigate the value of serum miR-143 level combined with MRI in predicting the early response to concurrent chemoradiotherapy (CCRT) in cervical cancer.Methods:A total of 85 patients with pathologically confirmed cervical cancer underwent conventional MRI, intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI), and dynamic contrast-enhanced MRI (DCE-MRI) before CCRT. The biopsy tissues and serum samples were collected. The differential expression of miRNA in the biopsy tissues was determined by microarray chip. The expression level of miR-143 in the serum samples was analyzed by qRT-PCR. All patients were divided into the non-residual and residual tumor groups according to post-treatment MRI. Pre-treatment clinical factors, MRI parameters and miR-143 between two groups were statistically analyzed by the univariate and multivariate analyses. The optimal thresholds and predictive performance for post-treatment incidence of residual tumors were estimated by drawing the ROC curve.Results:At one month after CCRT, there were 52 patients in the non-residual tumor group and 33 patients in the residual tumor group. In the residual tumor group, pre-treatment FIGO staging, apparent diffusion coefficient (ADC), D and V e were significantly higher (all P<0.05), whereas K trans value was significantly lower ( P<0.001) when compared to those in the non-residual tumor group. The miRNA array analysis showed that there were 16 miRNAs with differential expression levels between two groups (all P<0.05). Among them, the increase of miR-143 was the most significant in the residual tumor group. Compared with the residual tumor group, the expression level of serum miR-143 was significantly down-regulated in the non-residual tumor group ( P=0.002). Compared with the SiHa cells, the expression level of miR-143 in the SiHa-R cells was significantly up-regulated ( P<0.05). Multivariate analysis showed that only miR-143, D, K trans and V e were the independent prognostic factors. The combination of multi-parametric MRI and miR-143 exhibited the highest predictive performance (AUC=0.975), with a sensitivity of 84.8% and a specificity of 96.2%. Conclusion:The combination of multi-parametric MRI with miR-143 further improves the predictive performance for residual tumors after CCRT, which contributes to the personalized treatment of cervical cancer.

Cancer Research and Treatment 2021;53(4):1156-1165
Purpose:
Reduced quality of life after cystectomy has made bladder preservation a popular research topic for muscle-invasive bladder cancer (MIBC). Previous research has indicated significant tumor downstaging after neoadjuvant chemotherapy (NAC). However, maximal transurethral resection of bladder tumor (TURBT) was performed before NAC to define the pathology, impacting the real evaluation of NAC. This research aimed to assess real NAC efficacy without interference from TURBT and apply combined modality therapies guided by NAC efficacy.
Materials and Methods:
Patients with cT2-4aN0M0 MIBC were confirmed by cystoscopic biopsy and imaging. NAC efficacy was assessed by imaging, urine cytology, and cystoscopy with multidisciplinary team discussion. Definite responders (≤ T1) underwent TURBT plus concurrent chemoradiotherapy. Incomplete responders underwent radical cystectomy or partial cystectomy if feasible. The primary endpoint was the bladder preservation rate.
Results:
Fifty-nine patients were enrolled, and the median age was 63 years. Patients with cT3-4 accounted for 75%. The median number of NAC cycles was three. Definite responders were 52.5%. The complete response (CR) was 10.2%, and 59.3% of patients received bladder-sparing treatments. With a median follow-up of 44.6 months, the 3-year overall survival (OS) was 72.8%. Three-year OS and relapse-free survival were 88.4% and 60.0% in the bladder-sparing group but only 74.3% and 37.5% in the cystectomy group. The evaluations of preserved bladder function were satisfactory.
Conclusion
After stratifying MIBC patients by NAC efficacy, definite responders achieved a satisfactory bladder-sparing rate, prognosis, and bladder function. The CR rate reflected the real NAC efficacy for MIBC. This therapy is worth verifying through multicenter research.

Objective:To survey the status of illness and consultation within two weeks among residents in a community in Chengdu.Methods:A multi-stage stratified random sampling was used to carry out a questionnaire survey among the residents in a community in Chengdu during March to April 2019. The disease status, disease severity and consultation within two weeks were surveyed, and influencing factors of two-week illness were analyzed with logistic regression.Results:Among 2 714 participants, 715 had illness (900 times) within two weeks, with a two-week prevalence rate of 26.3%. The main symptoms were dizziness (6.4%, 58/900), cough (6.2%, 56/900), lumbago and leg pain (4.9%, 44/900), palpitations (3.3%, 30/900) and headache (3.1%, 28/900). The three most common diseases were hypertension (38.3%, 345/900), diabetes (19.3%, 174/900) and common cold (6.4%, 58/900). In this survey, the rate of two-week in bed was 20.6‰(56/2 714), and the rate of two-week off work was 4.8‰(13/2 714). Age, gender, education level and work status were the influencing factors of the illness in two weeks ( P<0.05). The choice of medical institution was also different among residents. Conclusion:The survey suggest that primary care should focus on the key groups of residents in the community such as elderly, women, low education level, retirement and unemployed; and it is necessary to strengthen the primary care institutions and two-way referral system of health care.
