Purpose To investigate the value of 99Tcm-(methoxyisobutvlisonitrile,MIBI)bone uptake on hungry bone syndrome(HBS)in renal secondary hyperparathyroidism(SHPT)after parathyroidectomy.Materials and Methods From June 2014 to December 2021,106 renal SHPT patients who underwent successful parathyroidectomy in Jiangyin Hospital Affiliated Nantong University were retrospectively enrolled.Visual analysis was used to evaluate the abnormal bone uptake of 99Tcm-MIBI.The patients were divided into HBS group and non-HBS group based on whether occurred HBS.The clinical features,laboratory indicators and 99Tcm-MIBI bone uptake were compared between the two groups.Results Of 106 renal SHPT patients,42(39.62%)patients with bone uptake on visual assessment,showed diffusely increased tracer accumulation,particularly in sternum,clavicle and ribs.The age in HBS group was younger than that in non-HBS group(t=-3.058),the alkaline phosphatase and parathyroid hormone level in HBS group were higher than that in non-HBS group(Z=-5.148,-2.218),the serum corrected calcium in HBS group was lower than that in non-HBS group(Z=-2.102),the positive rate and number of 99Tcm-MIBI bone uptake in HBS group was 50%and 2(1,3),which was higher than that of 28%and 1(1,1)in non-HBS group(χ2=5.344,Z=-2.970),respectively,all showed statistically significant difference(all P<0.05).Conclusion Renal SHPT patient with HBS after parathyroidectomy is commonly related to a high level of alkaline phosphatase and parathyroid hormone,and more likely to develop abnormal 99Tcm-MIBI bone uptake.

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.

The search period was from April 10, 2017 to April 10, 2022.Results:A total of 11 articles were included and 20 pieces of evidence were extracted, which were categorized into four categories: extracorporeal membrane oxygenation team composition and personnel qualifications, evaluation and monitoring, capacity management objectives, and capacity management measures.Conclusions:Based on a large amount of evidence of extracorporeal membrane oxygenation support for patient capacity management, this study can provide a reference basis for clinical workers to develop extracorporeal membrane oxygenation support treatment capacity management plans.

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.

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 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 evaluate the value of 68Ga-labeled prostate-specific membrane antigen( 68Ga-PSMA PET/CT)in the diagnosis of prostate cancer(PCa) and determination of the strategy on neurovascular bundle(NVB)preservation and lymphadenectomy before surgery. Methods:We retrospectively analyzed the clinical data of 46 patients with newly diagnosed PCa who underwent 68Ga-PSMA PET/CT from June 2018 to October 2019. The median age was 66.50 (60.00, 69.25) years old and the median PSA was 15.97(8.58, 33.10)ng/ml. Forty-one patients were diagnosed PCa and 5 were diagnosed with benign prostatic hyperplasia or prostatitis by 68Ga-PSMA PET/CT, 6 were diagnosed with lymph nodes metastasis. Forty patients underwent mpMRI, 33 were diagnosed PCa, and 6 were diagnosed with lymph nodes metastasis. Seventeen patients underwent 11C-choline PET/CT, 12 were diagnosed PCa, and 4 were diagnosed with lymph nodes metastasis. Among the 41 patients which were diagnosed PCa by 68Ga-PSMA PET/CT, 26 were confirmed with PCa by needling biopsy, 12 did not undergo the needling biopsy and 3 had negative biopsy; 22 were in the high-risk group, and 19 were in the low- and medium-risk group. All 41 patients underwent radical prostatectomy. The strategy of NVB preservation was determined by the position of the PCa reported by 68Ga-PSMA PET/CT. If the tumor was close to the unilateral prostate capsule, the healthy part of the NVB would be preserved. And if the tumor was limited in the prostate gland, bilateral NVB would be preserved. The NVB was preserved in 16 cases(6 cases unilateral and 10 cases bilateral). In addition to routine lymph node dissection for patients in the high-risk group, lymph node dissection was also performed on patients with 68Ga-PSMA PET/CT that showed positive lymph nodes in the low- and medium-risk groups. The paired chi-square or Fisher exact test was used to compare the sensitivity and specificity of 68Ga-PSMA PET/CT, mpMRI, and 11C-choline PET/CT for lesion detection. Spearman analysis was used to examine the correlation between the SUV max, Gleason score, and the PSA value before treatment. Results:Forty-one patients undergoing radical resection were diagnosed PCa by postoperative pathology, and no cancer tissue was observed at the surgical margin; the median Gleason score was 8(7, 9); 20 cases (48.8%) had a pathological stage ≤pT 2c; 21 cases (51.2%)≥pT 3; 7 cases were N+ (11 positive lymph nodes). Seven cases (17.1%) had complications of Clavien-Dindo ≤ grade 2 within 30 days after surgery, and there was no complication above grade 3 after surgery. The median follow-up time of the 41 patients was 16(12, 20). The rate of urinary control was 46.3%, 95.1%, and 100% after 1 month, 6 months, and 12 months follow-up respectively. Among the five patients that did not undergo surgery, the PSA value of 4 decreased after antibiotic treatment, and biopsy was performed in 1 case without PSA decreasing, and no carcinoma was found. The sensitivity of 68Ga-PSMA PET/CT on the primary PCa was 100%(41/41), which was significantly better than that of 11C-choline(80%, 12/15, P=0.016)and mpMRI (83.7%, 31/37, P=0.009), while no statistical significance was observed between the specificity of 68Ga-PSMA PET/CT (5/5)and 11C-choline PET/CT(2/2, P=1.000), 68Ga-PSMA PET/CT and mpMRI(1/3, P=0.107). Of the 41 patients that were diagnosed with PCa, the sensitivity of 68Ga-PSMA PET/CT to lymph nodes metastases(71.4%, 5/7) had a significant difference with that of mpMRI(16.7, 1/6, P=0.016), but no statistical difference with 11C-choline (75%, 3/4, P=1.000). Analysis of the relationship between SUV max of 68Ga-PSMA PET/CT, Gleason score, and PSA value before treatment revealed that the SUV max of 68Ga-PSMA PET/CT in patients with Gleason score ≥8 and <8 score were 19.60(9.58, 24.38) and 8.55 (5.18, 12.88); SUV max of patients with PSA values ≥20 ng/ml and <20 ng/ml before treatment were 19.40 (13.00, 23.50) and 8.40 (5.35, 13.95), respectively, the differences were statistically significant (all P<0.05). Conclusions:68Ga-PSMA PET/CT had high sensitivity and specificity for the diagnosis of primary prostate cancer lesions, but the sensitivity for the diagnosis of lymph node metastasis was not enough to guide the preoperative decision of whether to remove the lymph node and the scope of the removal. However, the treatment strategy of whether to retain NVB could be formulated according to the tumor location displayed by 68Ga-PSMA PET/CT before surgery.

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.

Objective:To analyze the molecular characteristics of Echovirus 11 (Echo11) strains isolated in Xiangyang, Hubei Province from 2016 to 2017 based on the sequences of VP1 gene.Methods:Rectal and throat swab specimens were collected from children with hand, foot and mouth disease (HFMD) in Xiangyang from 2016 to 2017. Echo11 strains were detected by real-time reverse transcriptase PCR (RT-PCR) and isolated after cultured in human rhabdosarcoma (RD) cells. The VP1 regions of Echo11 strains isolated from RD cells and the whole genomes of three representative Echo11 strains were amplified by conventional RT-PCR and the sequences were analyzed. DNAStar7.0 (MegAlign) and MEGA6.0 (Data) were used to analyze the homology and mutation sites in nucleotide and amino acid sequences. Neighbor-joining method was used to construct phylogenetic trees. Recombination analysis was performed with SimPlot software (BootScanning).Results:A total of 11 Echo11 strains were isolated from 3 494 HFMD cases, accounting for 0.31%. They were highly homologous in the VP1 gene. These strains shared 98.4%-100.0% homology in nucleotide sequences and 98.3%-100.0% homology in amino acid sequences. The homology between the 11 Echo11 strains and the prototype strain (Echo11/Gregory, X80059) was 73.9%-74.8% in nucleotide sequences and 87.7%-88.7% in amino acid sequences. All of the Echo11 strains circulating in Xiangyang were classified into lineage D, having a similarity to the strains circulating in some regions of mainland China since 2013. In multiple regions of the genome, the Echo11 strains isolated in Xiangyang were highly similar to the Henan Echo1 strains in 2010 and the Hubei Echo6 strains in 2015, suggesting there was recombination within the genome of Echo11 strains in Xiangyang.Conclusions:The Echo11 strains circulating in Xiangyang from 2016 to 2017 belonged to lineage D and were recombinant strains.

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.
