Objective To assess the value of the MRI-based ovarian-adnexal reporting and data system (O-RADS MRI) for the diagnosis of adnexal masses. Methods A total of 407 patients who underwent dynamic contrast enhancement (DCE)-MRI and pathological examination (gold standard) at the Department of Radiology,Central Hospital of Wuhan between May 2017 and December 2022 were enrolled in this study.Two radiologists performed the O-RADS MRI scoring of adnexal masses according to MRI features and calculated the malignancy rate of adnexal masses by O-RADS MRI score,enhancement type,and mass type.Moreover,receiver operating characteristic curves were established to further evaluate the diagnostic values of O-RADS MRI score,enhancement type,and mass type for adnexal masses. Results A total of 502 adnexal masses were identified in the 407 patients enrolled in this study,including 364 benign masses and 138 malignant masses (including junctional masses).Radiologist 1 reported the malignancy rates of 0,0,5.4%,80.0%,and 89.7% and radiologist 2 reported the malignancy rates of 0,0,5.8%,86.2%,and 83.0% for the adnexal masses with the O-RADS MRI scores of 1-5,respectively.With O-RADS MRI ≥4 indicating malignant masses,the sensitivity,specificity,accuracy,positive predictive value,negative predictive value,false negative rate,and false positive rate were 94.2%,93.6%,93.8%,84.9%,97.7%,2.3%,and 15.1% for radiologist 1 and 93.4%,93.6%,93.6%,85.4%,97.4%,3.6%,and 14.6% for radiologist 2,respectively.The malignancy rates of the adnexal masses presenting no enhancement,cystic wall enhancement,type Ⅰ curve,type Ⅱ curve,and type Ⅲ curve were 0,1.3%,5.7%,81.2%,and 89.0% as reported by radiologist 1 and 0,1.2%,11.3%,87.6%,and 80.0% as reported by radiologist 2,respectively.The malignancy rates of the adnexal masses that were cystic lesions,cystic segregated lesions,solid lesions,cystic solid lesions,and cystic solid segregated lesions were 0,7.1%,38.7%,79.1%,and 89.8% as reported by radiologist 1 and 0,8.1%,37.8%,72.4%,and 89.6% as reported by radiologist 2,respectively.With type Ⅱ and type Ⅲ curves as the criteria for malignancy,the sensitivity of radiologists 1 and 2 was lower for cystic segregated lesions,both at 50.0%.For the masses containing solid components,radiologists 1 and 2 demonstrated low specificity,which was 57.7% and 56.5%,respectively.False-positive masses contained solid components and were mostly fibroadenomas or adnexal leiomyomas,while false-negative masses were mostly junctional cystadenomas with no or few solid components. Conclusions The O-RADS MRI risk stratification has a high diagnostic value for adnexal masses.Further evaluation and refinement are needed to reduce the false-positive rate.

Uric acid (UA) is the final product of purine metabolism in human body,and its metabolic disorder will induce hyperuricemia (HUA).The occurrence and development of HUA are associated with a variety of pathological mechanisms such as oxidative stress injury,activation of inflammatory cytokines,and activation of renin-angiotensin-aldosterone system.These mechanisms directly or indirectly affect the bioavailability of endogenous nitric oxide (NO).The decrease in NO bioavailability is common in the diseases with high concentration of UA as an independent risk factor.In this review,we summarize the mechanisms by which high concentrations of UA affect the endogenous NO bioavailability,with a focus on the mechanisms of high-concentration UA in decreasing the synthesis and/or increasing the consumption of NO.This review aims to provide references for alleviating the multisystem symptoms and improving the prognosis of HUA,and lay a theoretical foundation for in-depth study of the correlations between HUA and other metabolic diseases.

This study aimed to compare the predictive value of six selected anthropometric indicators for benign prostatic hyperplasia (BPH). Males over 50 years of age who underwent health examinations at the Health Management Center of the Second Xiangya Hospital, Central South University (Changsha, China) from June to December 2020 were enrolled in this study. The characteristic data were collected, including basic anthropometric indices, lipid parameters, six anthropometric indicators, prostate-specific antigen, and total prostate volume. The odds ratios (ORs) with 95% confidence intervals (95% CIs) for all anthropometric parameters and BPH were calculated using binary logistic regression. To assess the diagnostic capability of each indicator for BPH and identify the appropriate cutoff values, receiver operating characteristic (ROC) curves and the related areas under the curves (AUCs) were utilized. All six indicators had diagnostic value for BPH (all P ≤ 0.001). The visceral adiposity index (VAI; AUC: 0.797, 95% CI: 0.759-0.834) had the highest AUC and therefore the highest diagnostic value. This was followed by the cardiometabolic index (CMI; AUC: 0.792, 95% CI: 0.753-0.831), lipid accumulation product (LAP; AUC: 0.766, 95% CI: 0.723-0.809), waist-to-hip ratio (WHR; AUC: 0.660, 95% CI: 0.609-0.712), waist-to-height ratio (WHtR; AUC: 0.639, 95% CI: 0.587-0.691), and body mass index (BMI; AUC: 0.592, 95% CI: 0.540-0.643). The sensitivity of CMI was the highest (92.1%), and WHtR had the highest specificity of 94.1%. CMI consistently showed the highest OR in the binary logistic regression analysis. BMI, WHtR, WHR, VAI, CMI, and LAP all influence the occurrence of BPH in middle-aged and older men (all P ≤ 0.001), and CMI is the best predictor of BPH.

Aim To investigate the effect of terpinene 4-alcohol(T4O)on the malignant behavior of colorectal cancer cell RKO and HCT116 and the underlying mechanism. Methods RKO and HCT116 cells were treated with 0, 1, 2, 4 μmol·L-1 T4O and 4 μmol·L-1 5-Fu, respectively. The proliferation, clonal formation, apoptosis, cell cycle, migration and invasion of RKO and HCT116 cells were detected by CCK-8, colony formation, flow cytometry, wound healing and Transwell assay; the expressions of E-Cadherin, N-Cadherin, p21, CyclinB1 and cleaved-Caspase7 in each group of cells were detected by Western blot. Based on pharmacophore, the target of T4O was analyzed and then the effects of T4O on the expression and degradation rate of NR3C1 were explored. NR3C1 knockdown cells were constructed, and the effects of NR3C1 knockdown on the proliferating and migrating inhibition induced by T4O were detected by wound healing and CCK-8 assay. Results T4O significantly inhibited the proliferation, colony formation, migration and invasion of RKO and HCT116 cells, as well as induced apoptosis and G1 phase arrest(P all <0. 05). The effect of T4O was better than that induced by 5-Fu with the same dose. T4O obviously reduced N-Cadherin and Cyclin B1 expression, and elevated the E-Cadherin, p21 and cleaved-Caspase7 expression(P all <0. 05). A total of 10 targets of T4O were discovered, among which NR3C1 had the highest binding score. After T4O treatment, NR3C1 level in cells increased obviously, and the degradation rate decreased markedly(P<0.05). NRC3C1 knockdown significantly relieved the inhibitory effects of T4O on cell prolfieration and migration(P<0.05). Conclusion T4O can inhibit the malignant behavior of colorectal cancer cells RKO and HCT116 by maintaining the stability of NR3C1 protein.

Abstract: Objective　To understand the kdr (knockdown resistance, kdr) gene mutation of the voltage-gated sodium channel (VGSC) of Anopheles sinensis in Yunnan Province. Methods　From 2018 to 2019, mosquitoes were collected in Luoping County, Suijiang County, Tengchong City, Yingjiang County, Yuanjiang County and Mengla County in Yunnan Province. The collected mosquitoes were morphologically identified as Anopheles sinensis and genomic DNA was extracted by kits. The DNA templates were sequenced after PCR amplification and the sequencing results were identify as Anopheles sinensis by homology alignment in NCBI. After the ⅡS5 and ⅡS6 fragments of the sodium channels in Anopheles sinensis were amplified and sequenced, the sequencing results were multiple aligned by DNAMAN software, and the mutations were analyzed one by one with BioEdit software to determine the kdr allele types and genotypes, and the frequencies were calculated. Results This survey amplified 287 sequences, and the sequence maps showed that 1014 loci had three alleles, including wild type TTG/L (89.20%), mutant type TTT/F (9.76%) and TCG/S (1.04%). Five genotypes: homozygous wildtype L/L (85.02%), homozygous mutant F/F (6.27%) and S/S (0.35%), heterozygous mutant L/F (6.97%) and L/S (1.39%). The wild type allele TTG/L was the main allele in six sampling sites except Suijiang County. The frequency of wild type allele in Tengchong City was the highest (100.00%). That is, no mutation was detected, while the rest of counties occurred different degrees of mutation at 1014 loci. The frequency of mutant allele in Suijiang County was the highest, reaching 55.68%. Luoping County, Mengla County and Suijiang County had two mutant types. Yingjiang County and Yuanjiang County had one heterozygous mutant L/F. Conclusion　Wild type L1014 (TTG/L) is still dominant in most areas of Yunnan Province. The kdr mutation type is mainly L1014F, followed by L1014S, and the mutation frequency is lower than that in central provinces of China.

Objective:To observe the clinical efficacy of modified Qiaohetang and Xiehuangsan in the treatment of acne due to dampness-heat accumulation and its influence on the levels of inflammatory factors and sex hormones. Method:One hundred and sixty-eight eligible patients were divided into an observation group （84 cases） and a control group （84 cases） according to the random number table. Adapalene gel was applied externally in both groups， one time per day. In the control group， Jinhua Xiaocuo pills was taken orally， 4 g per time， three times a day. In the observation group， the modified Qiaohetang and Xiehuangsan was provided for oral administration， one bag per day. The treatment lasted for eight weeks. The Global Acne Grading System （GAGS） score， skin lesion count， dampness-heat accumulation syndrome score， and Dermatology Life Quality Index （DLQI） score were recorded before and after treatment， followed by the detection of interleukin-8 （IL-8）， IL-10， IL-17， interferon-γ （IFN-γ）， free testosterone （FT）， estradiol （E₂） and sex hormone binding globulin （SHBG） before and after treatment as well as the safety evaluation. Result:The GAGS， dampness-heat accumulation syndrome， and DLQI scores of the observation group were lower than those of the control group （P<0.01）. The counts of inflammatory skin lesions （papule and pustule）， non-inflammatory skin lesions， and total skin lesions in the observation group declined in contrast to those in the control group （P<0.01）. The IL-8， IL-17， IFN-γ and FT levels of the observation group were decreased as compared with those of the control group （P<0.05， P<0.01）， while the IL-10， E₂， and SHBG levels were increased （P<0.01）. The overall response rate in clinical symptom alleviation of the observation group was 93.67%（74/79）， which was higher than 81.82%（63/77） of the control group （χ²=5.121， P<0.05）. The overall response rate in dampness-heat accumulation syndrome relief of the observation group was 92.41% （73/79）， still higher than 79.22% （61/77） of the control group （χ²=5.595， P<0.05）. No adverse reactions occurred after the oral administration of Chinese medicinal preparations. Conclusion:The modified Qiaohetang and Xiehuangsan combined with adapalene gel can reduce the skin lesion count and severity， relieve both clinical symptoms and dampness-heat accumulation syndrome， regulate the inflammatory response and sex hormones， and improve the quality of life of patients with acne of dampness-heat accumulation syndrome without inducing side effects.
