Objective:To study the diagnostic value of artificial intelligence B-ultrasound image computer-aided diagnosis system (hereinafter referred to as intelligent ultrasound system) in adult goiter.Methods:In June 2022 and March 2023, two phases of thyroid disease survey were carried out in 4 cities in Anhui Province. One village was selected in each city, and 250 adults were selected as survey subjects in each village. Adult bilateral thyroid area was scanned by both intelligent ultrasound system and conventional ultrasound scanning equipment, and the effectiveness of intelligent ultrasound system in the diagnosis of goiter was analyzed based on the results of conventional ultrasound examination. Receiver operating characteristic (ROC) curve was drawn, and Kappa test was used to analyze the consistency between intelligent ultrasound system and conventional ultrasound examination in the diagnosis of goiter. At the same time, Spearman correlation analysis and Bland-Altman method were used to evaluate the consistency of the two methods in measuring thyroid volume.Results:After screening and removing outliers and missing values, a total of 910 adults were included, including 253 males (27.80%) and 657 females (72.20%). The age was (45.92 ± 10.20) years old, ranging from 18 to 60 years old. The sensitivity, specificity, and accuracy of the intelligent ultrasound system for diagnosing adult goiter were 80.00%, 99.67%, and 99.56%, respectively. The area under the ROC curve (AUC) was 0.996, which was consistent with the results of conventional ultrasound examination for diagnosing goiter ( κ = 0.67, P < 0.001). After controlling for variables such as gender, thyroid function, and thyroid nodules, the intelligent ultrasound system showed good consistency with conventional ultrasound examination in the diagnosis of goiter in females, adults with thyroid dysfunction, and adults without thyroid nodules ( κ = 0.66, 0.80, 0.80, P < 0.001). The consistency in the diagnosis of goiter in adults with thyroid nodules was moderate ( κ = 0.56, P < 0.001). Spearman correlation analysis showed a highly positive correlation between the measurement results of adult thyroid volume by intelligent ultrasound system and conventional ultrasound examination ( r = 0.88, P < 0.001). The Bland-Altman method results showed that only 4.62% (42/910) of points in adults were outside the 95% consistency limit, indicating good consistency between intelligent ultrasound system and conventional ultrasound examination in measuring thyroid volume (< 5%). The proportion of points outside the 95% consistency limit in males, adults with thyroid dysfunction, and adults with thyroid nodules was 6.72% (17/253), 5.83% (12/206), and 6.45% (12/186), respectively. Conclusions:The intelligent ultrasound system has certain diagnostic value for adult goiter and has good consistency with conventional ultrasound examination for thyroid volume measurement. However, the accuracy of diagnosis for males and adults with thyroid nodules still needs to be improved.

Vitamin D works in the active form 1，25（OH） 2D 3 after binding to vitamin D receptor.Vitamin D deficiency is common in children with renal disease，and the abnormalities of vitamin D and its metabolic pathways are closely related to the occurrence and development of proteinuria and the deterioration of renal function.Vitamin D not only plays its classic role in maintaining calcium and phosphorus homeostasis，but also protects the kidney by improving the immune function of children，blocking the renin-angiotensin-aldosterone system，preventing the occurrence and development of proteinuria，alleviating the damage of podocytes，and delaying renal interstitial fibrosis.Therefore，this article reviews the research progress of vitamin D and its receptor gene polymorphism and kidney disease，in order to serve the clinical practice.

Background::Ainuovirine (ANV) is a new generation of non-nucleoside reverse transcriptase inhibitor for the treatment of human immunodeficiency virus (HIV) type 1 infection. This study aimed to evaluate the population pharmacokinetic (PopPK) profile and exposure-response relationship of ANV among people living with HIV.Methods::Plasma concentration-time data from phase 1 and phase 3 clinical trials of ANV were pooled for developing the PopPK model. Exposure estimates obtained from the final model were used in exposure-response analysis for virologic responses and safety responses.Results::ANV exhibited a nonlinear pharmacokinetic profile, which was best described by a two-compartment model with first-order elimination. There were no significant covariates correlated to the pharmacokinetic parameters of ANV. The PopPK parameter estimate (relative standard error [%]) for clearance adjusted for bioavailability (CL/F) was 6.46 (15.00) L/h, and the clearance of ANV increased after multiple doses. The exposure-response model revealed no significant correlation between the virologic response (HIV-RNA <50 copies/mL) at 48 weeks and the exposure, but the incidence of adverse events increased with the increasing exposure ( P value of steady-state trough concentration and area under the steady-state curve were 0.0177 and 0.0141, respectively). Conclusions::Our PopPK model supported ANV 150 mg once daily as the recommended dose for people living with HIV, requiring no dose adjustment for the studied factors. Optimization of ANV dose may be warranted in clinical practice due to an increasing trend in adverse reactions with increasing exposure.Trial registration::Chinese Clinical Trial Registry https://www.chictr.org.cn (Nos. ChiCTR1800018022 and ChiCTR1800019041).

BACKGROUND: The clinical features of enthesitis in patients with psoriatic arthritis (PsA) have been reported in some Western countries, but data in China are very limited. This study aimed to describe the characteristics of enthesitis in Chinese patients with PsA and compared them with those in other cohorts. METHODS: Patients with PsA enrolled in the Chinese Registry of Psoriatic Arthritis (CREPAR) (December 2018 to June 2021) were included. Data including demographics, clinical characteristics, disease activity measures, and treatment were collected at enrollment. Enthesitis was assessed by the Spondyloarthritis Research Consortium of Canada (SPARCC), Maastricht ankylosing spondylitis enthesitis score (MASES), and Leeds enthesitis index (LEI) indices. A multivariable logistic model was used to identify factors related to enthesitis. We also compared our results with those of other cohorts. RESULTS: In total, 1074 PsA patients were included, 308 (28.7%) of whom had enthesitis. The average number of enthesitis was 3.3 ± 2.8 (range: 1.0-18.0). More than half of the patients (165, 53.6%) had one or two tender entheseal sites. Patients with enthesitis had an earlier age of onset for both psoriasis and arthritis, reported a higher proportion of PsA duration over 5 years, and had a higher percentage of axial involvement and greater disease activity. Multivariable logistic regression showed that axial involvement (odds ratio [OR] 2.21, 95% confidence interval [CI], 1.59-3.08; P <0.001), psoriasis area and severity index (PASI) (OR: 1.03, 95% CI: 1.01-1.04; P = 0.002), and disease activity score 28-C reactive protein (DAS28-CRP) (OR: 1.25, 95% CI: 1.01-1.55; P = 0.037) were associated with enthesitis. Compared with the results of other studies, Chinese patients with enthesitis had a younger age, lower body mass index (BMI), a higher rate of positive human leukocyte antigen (HLA)-B27, more frequent dactylitis, and a higher proportion of conventional synthetic disease-modifying antirheumatic drugs' (csDMARDs) use. CONCLUSIONS Enthesitis is a common condition among Chinese patients with PsA. It is important to evaluate entheses in both peripheral and axial sites.

Objective:To investigate the clinical features of pregnant associated Takotsubo cardiomyopathy (PTCM).Methods:We reviewed reported PTCM cases published from January 2007 to June 2022 using the keywords "Tako-tsubo cardiomyopathy""Takotsubo cardiomyopathy" "stress cardiomyopathy" AND "parturition" "pregnancy" "cesarean delivery" "postpartum" "peripartum" "eclampsia" "abortion" in Pubmed and Web of Science databases and the corresponding Chinese words in Wanfang and Chinese Medical Journal Network. Age, obstetric history, mode of delivery, mode of anesthesia, etiological factors, clinical manifestations, treatment, and prognosis of PTCM were recorded. Descriptive statistical analysis was adopted.Results:A total of 55 articles were included, covering 60 patients with PTCM. (1) Age and time of onset: The age of onset was (32.4±6.0) years old. PTCM occurred most frequently during labor [42% (25/60)] and within one day postpartum [32% (19/60)] and during the gestational period [13%(8/60), 33.0 weeks (24.5-37.7 weeks)]. (2) Delivery-related factors: There were 38% (16/42) primiparas and 60% (25/42) multiparas. Among them, 67% (38/57) and 18% (10/57) were delivered by cesarean section and vaginal delivery, respectively. PCTM often lacks obvious triggers [40% (24/60)], with the most common inducing factor being pregnancy-related diseases [27% (16/60)]. (3) Clinical features: The initial symptoms of PTCM were dyspnea [44% (26/59)], followed by chest pain accompanied by dyspnea [17% (10/59)]. The most common subtype of PTCM was the apical type [45% (26/58)], followed by the basal type [24% (14/58)], while the biventricular type was the least common [3% (2/58)] in the PTCM classification. The left ventricular ejection fraction was (31.6±12.1) % at the onset of PTCM, which recovered to (58.2±7.6) % at discharge. PCTM was often complicated by pulmonary edema [67% (40/60)] and cardiogenic shock [55% (33/60)]. (4) Treatment and prognosis: Patients with PCTM usually require noninvasive or invasive ventilator-assisted ventilation [40% (23/58)]. One pregnant woman and five neonates died, while the remaining patients recovered well.Conclusions:PTCM should be considered in differential diagnosis of patients experiencing dyspnea and chest pain during labor and pregnancy. PTCM patients are younger and have more pulmonary edema and cardiogenic shock. Mechanical ventilation is often required, but the prognosis is favorable.

Objective:To explore the morbidity, clinical features and mortality of unilateral pulmonary edema (PE) in the intensive care unit (ICU).Methods:Clinical data of PE patients in ICU between January 2018 and January 2021 were retrospectively collected. All patients were divided into the bilateral PE and unilateral PE groups according to imaging manifestations. Etilogy, clinical performance, cardiac ultrasound parameters, complications, treatment and prognosis were compared between the two groups. Binary logistic regression analysis was used to screen out the risk factors of death.Results:Of the 314 PE patients, 14 (4.5%) were unilateral PE patients , and 11 (78.5%) were right-sided unilateral PE. There were no differences in age, gender, heart rate, respiratory rate and left ventricular eject fraction between the unilateral and bilateral PE groups. Compared with the bilateral PE group, systolic and diastolic blood pressure were significantly lower in the unilateral PE group [128 (102.7-138) mmHg vs. 135 (116-166) mmHg, 72 (54-88.2) mmHg vs. 82 (69-97.7)mmHg, respectively]. The incidence of cardiac arrest and hospital mortality were higher in the unilateral PE group [28.6% vs. 8.0%, 42.9% vs. 10%, all P<0.05]. Binary logistic regression analysis showed that age, unilateral PE, and use of vasoactive agent were associated with poor prognosis. Odds ratio of unilateral PE and use of vasoactive agent were 17.78 and 11.67, respectively. Conclusions:Unilateral PE is not rare, which is an independent risk factors for mortality and should be promptly recognized to avoid delays in treatment.

Objective:To investigate the risk factors for biochemical recurrence after radical prostatectomy.Methods:The clinical data of 558 radical prostatectomy patients admitted to the First Affiliated Hospital of Air Force Military Medical University from January 2010 to December 2020 were retrospectively analyzed. The average age was 67.9 (40-87) years old, and the average body mass index was 24.56 (15.12-35.94) kg/m 2. The average PSA was 41.07 ng/ml, including 48 cases<10 ng/ml, 98 cases 10-20 ng/ml, and 412 cases>20 ng/ml. There were 123, 214, 118, 89, and 14 cases with biopsy Gleason 6-10 score, respectively. The clinical stage : 90 cases in ≤T 2b, 273 cases in T 2c, and 195 cases in ≥T 3 . 558 cases underwent radical prostatectomy, including 528 robotic-assisted laparoscopic surgery, 25 laparoscopic surgery, and 5 open-surgery. The risk factors for postoperative biochemical recurrence were analyzed by Cox regression. Results:A total of 63 patients had postoperative pathological stage pT 2a, 32 patients had pT 2b, 241 patients had pT 2c, and 222 patients had ≥pT 3. A total of 210 cases developed biochemical recurrence after surgery, and the mean time to biochemical recurrence was 33.3 (3-127) months after the radical prostatectomy. The biochemical recurrence rates at 1, 3, and 5 years were 9.7% (54/558), 21.5% (120/558), and 31.7% (177/558), respectively. Among pT 2a and pT 2b patients, 7 (11.1%) and 4 (12.5%) cases developed biochemical recurrence, respectively. Among pT 2c stage patients, 145 (60.17%) cases had positive cut margins, treated with androgen-deprivation therapy (ADT) after surgery. 68 (28.21%) cases of pT 2c stage patients had biochemical recurrence at mean 36.1 (3-106)months after the radical prostatectomy. Among ≥pT 3 patients, 147 patients with positive margins, perineural invasion, seminal vesicle invasion and positive pelvic lymph nodes were treated with postoperative androgen deprivation therapy (ADT) + radiotherapy. 98 of 147 patients (66.67%) had biochemical recurrence, and the average time to biochemical recurrence was 30.6 (24-98) months.75 patients of ≥pT 3 without positive margins, perineural invasion, seminal vesicle invasion or positive pelvic lymph nodes, were treated with postoperative ADT. 33 of them (44%) had biochemical recurrence, and the average time to biochemical recurrence was 32.5 (21-106) months. 5-and 10-year survival rates of 210 patients with biochemical recurrence were 89.05% (187/210) and 78.09% (164/210) respectively, 5- and 10-year tumor-specific survival rates were 92.57% and 87.69%, respectively. 46 of 210 cases died, of which 31 (67.39%) died from prostate cancer, and 15 cases (32.61%) died from cardiovascular and cerebrovascular diseases. Multifactorial Cox regression analysis showed that patient's age ≥70 years, initial PSA > 20ng/ml, ≥pT 3 and Gleason score ≥7 were independent risk factors for biochemical recurrence. Conclusions:After radical prostatectomy, patients were treated according to their pathological stage and surgical margins. Patients with positive margins have a higher risk of biochemical recurrence. The independent risk factors for biochemical recurrence included age ≥70 years, initial PSA > 20ng/ml, ≥pT 3 and Gleason score ≥7.

ObjectiveTo understand the correlation between air quality and pollutants in three underground subway stations in Shanghai and their influencing factors， in order to provide a reference for improving the ambient air quality of rail transit and enhancing control measures. MethodsAir quality was monitored in summer， autumn， and winter of 2021 at the halls， platforms， carriages and fresh air wells of three underground stations of Shanghai metro line 9， with indicators including temperature， relative humidity， wind speed， CO₂， PM₁， PM_2.5， PM₁₀， total airborne bacteria， total airborne fungi， and passenger flow. Correlation analysis and multiple regression analysis were used to explore the association between pollutant indicators and environmental indicators. ResultsThe relative humidity of air at three stations did not meet the national health standards （GB 37488‒2019）， with an exceedance rate of 66.7%； the PM₁₀ detection index at individual stations in autumn and winter did not meet the national health standards （GB 37488‒2019）， with an exceedance rate of 20.6%， while the rest of the indexes basically met the requirements of the standards. Spatially， the CO₂ and wind speed in the carriage were higher than in other areas of the station； the concentration of particulate matter in the fresh air well and the total number of airborne fungi were higher than in other areas. Seasonally， the concentration of particulate matter was higher in winter than in summer and autumn， while the microbial indexes were higher in summer than in autumn and winter. The correlation and regression analysis showed that the passenger flow was significantly and positively correlated with the CO₂ concentration； the temperature and humidity were significantly and negatively correlated with the particulate matter concentration and positively correlated with the microbial index. The correlation and multiple regression analysis showed that the subway station health indicators were significantly affected by the ambient temperature， humidity， seasonal and monitoring regional factors， while the influence of sampling time had no significant effect on the differences in the health indicators. ConclusionThe air quality of the three stations in this survey generally meets the requirements of health standards. The changes of air pollutants in subway stations show obvious spatial and temporal characteristics. The passenger flow and temperature and humidity， as well as sample sites are important factors affecting the concentration of particulate matter and the level of air microorganisms， which need to be considered when formulating the corresponding protection strategies.

Background Air quality health index (AQHI) has been widely used to quantify the health effects of multiple pollutants observed in population-based epidemiological studies, and can better reflect the widespread linear non-threshold between air pollution and health effects. Objective To explore an AQHI for pediatric respiratory diseases (AQHI_r) in Shanghai and evaluate its feasibility. Methods The daily numbers of hospital outpatient visits for pediatric respiratory diseases from 2015 to 2019 were obtained from five general hospitals in Xuhui, Baoshan, Hongkou, Jinshan, and Chongming Districts of Shanghai. Monitoring data on air pollutants (PM_2.5, PM₁₀, SO₂, NO₂, and O₃), air quality index (AQI), and meteorological variables (temperature, relative humidity, air pressure, and wind speed) were collected from five air quality monitoring sites nearest to selected hospitals. Time-series analysis using generalized additive model (GAM) was conducted to estimate the associations between respiratory-related pediatric outpatient visits and the concentrations of air pollutants. The sum of excess risk (ER) of hospital outpatient visits was used to construct AQHI_r. To assess the predictive power of AQHI_r, the associations of AQHI_r and AQI with the number of pediatric respiratory outpatient visits in three hospitals in Xuhui, Hongkou, and Chongming districts were compared. Results Air pollutants had various effects on respiratory diseases outpatient visits. PM_2.5, NO₂, and O₃ had most significant impacts on lag0 day and the associated ERs of hospital outpatient visits for each 10 μg·m⁻³ increase in pollutant concentration were 1.27% (95%CI: 0.88%-1.66%), 0.75% (95%CI: 0.40%-1.11%), and 0.36% (95%CI: 0.10%-0.62%), respectively. PM₁₀ and SO₂ had most significant impacts on lag3 day and the associated ERs of hospital outpatient visits for each 10 μg·m⁻³ increase in pollutant concentration were 0.81% (95%CI: 0.51%-1.12%) and 5.64% (95%CI: 3.37%-7.96%), respectively. There were significant effects of combinations of two pollutants among PM_2.5, PM₁₀, NO₂, SO₂, and O₃ except for PM₁₀+NO₂, SO₂+PM_2.5, and SO₂+NO₂ (P<0.05). According to the results of single-pollutant and two-pollutant models, PM_2.5, NO₂, SO₂, and O₃ were selected to construct AQHI_r. The comparison showed that for every interquartile range increase in AQHI_r, the ER for pediatric outpatient visits was higher than that for the value corresponding to AQI. Conclusion Air pollutants in Shanghai have an impact on the number of pediatric respiratory outpatient visits. The AQHI_r based on and outpatient visits for pediatric respiratory diseases can be a sensitive index to predict the effects of air pollution on children's respiratory health.
