Objective: To observe the association between puberty development and thyroid function among school-aged girls in Minhang District of Shanghai, in order to explore the effect of puberty development on thyroid function. Methods: The study was based on a cohort of adolescent girls recruited in iodine-suitable areas of Minhang District, and the baseline and follow-up survey have been carried out from January to March 2019. The method of phased cluster sampling was used to select one junior high school in the east, south, north and middle of Minhang District, Shanghai, respectively. Finally, 464 new junior high school girls were included in the Cohort study for physical examination, and girls were followed up from January to March 2021. The Puberty Development Scale (PDS) was used to assess the stage of puberty. Serum thyroid stimulating hormone (TSH), free triiodothyronine (FT3), and free thyroxine (FT4) were determined for each participant. Thyroid homeostasis structure parameters (THSPs) was calculated. Changes of Thyroid hormones at baseline and follow-up were compared by Wilcoxon signed rank sum test. Multiple linear regression analyses were used to evaluate the associations of thyroid hormones (THs) and THSPs changes with pubertal develepment. Results: Serum TSH levels of female studentds decreased significantly, while their FT3 and FT4 levels increased significantly during the study period ( Z=-10.53, -4.71, -12.46, P <0.01). In multiple linear regression analysis after adjustment for co-variables (including baseline age, change of BMI and waist circumference), FT4 and thyroid feedback quantile-based index (TFQI) in the higher puberty category scores changes (△PCS) group were further reduced compared with those in the low △PCS group ( β =-0.66, -0.55 ). Compared to the late puberty at baseline and follow-up (BLFL) group, FT4 and TFQI showed higher decline in the pre-puberty at baseline and late puberty at follow-up (BPFL) group with the pre-puberty at baseline and end of puberty at follow-up (BPFT) group ( β =-0.55, -0.44)( P <0.05). There were no association of △TSH, △FT3, △FT4/FT3 and TSH index changes (△TSHI) with △PCS or the puberty pattern. Conclusion Serum TSH decreases while serum FT3 and FT4 increase among girls during puberty. Both the initial stage and the velocity of pubertal development are related to thyroid hormone fluctuations.

Objective:To evaluate the mid-term complication rates of the Hui-Jing one-stage procedure (lingual mucosa combined with longitudinal preputial island flap onlay urethroplasty + tubularized incised plate glansplasty)versus the classic Bracka staged surgery for children with severe hypospadias.Methods:A retrospective analysis was conducted on clinical data of 75 children with proximal hypospadias who were treated at the Seventh Medical Center of PLA General Hospital from March 2017 to June 2022. Of these patients, 31 cases (15 cases penoscrotal type and 16 cases perineal type) were underwent the Bracka two-stage surgery with a median age of 38 months (24.0, 44.5) and 44 cases underwent the Hui-Jing one-stage procedure (23 cases penoscrotal type and 21 perineal type) with a median age of 40.5 months (20.75, 90.5). The length of urethral plate defect after correction of penile curvature was (4.30±0.84)cm in the Bracka group and (4.56±0.79)cm in the Hui-Jing group, which also showed no significant difference.There was no statistically significant difference of the median age and the position of preoperative urethral opening between the two groups( P=0.47, P=0.74). The first stage of Bracka repair consists of orthoplasty and urethral bed substitution with free preputial graft. After 6 months, the urethral plate created from free graft was tabularized to form neourethra; Hui-Jing procedure group used the free lingual mucosal as urethral plate substitution, then we conducted longitudinal preputial island flap Onlay and Snodgrass phalloplasty. The incidence of postoperative urethral fistula, urethral stricture and urethral diverticulum was compared between the two groups of cases and the difference in efficacy between the two procedures was assessed. Results:Among the 75 patients included in the study, there was no statistically significant difference in age or location of urethral meatus between the Bracka and Hui-Jing groups. In Bracka group, 9 cases of urethral stricture (29.0%), 6 case of urethral fistula (19.4%), and 2 cases of urethral diverticulum (6.5%) occurred after surgery, while 12 cases of urethral fistula (27.3%) and 3 case of urethral fistula (6.8%) occurred in the Hui-Jing group. No urethral stricture occurred in Hui-Jing group. There was no statistically significant difference in overall incidence of complications between the two groups [17/31(54.8%) vs.15/44(34.1%), P=0.12]. The incidence of urethral fistula and urethral diverticulum show no significant differences between two groups(19.4% vs 27.3, P=0.61, 6.5% vs. 6.8%, P=0.13). The number of operation in Bracka group was (2.68±1.03) and the hospitalization cost was (12 984.63±3 808.15) Yuan, while the number of operation in Hui-Jing group was (1.36±0.53) and the hospitalization cost was (8 490.54±3 136.84) Yuan. Conclusions:The Hui-Jing one-stage procedure can be used for the surgical treatment of children with severe hypospadias. There is no urethral stricture happened in Hui-Jing group, while the general complication incidence and incidence of urethral fistula and diverticulum show no differences.

Objective To detect the radiation of ¹³¹I in treatment site of a grade A tertiary hospital. Methods A total of 25 patients with thyroid cancer were administrated ¹³¹I at a total dose of 82880 MBq. After administration, the ambient dose equivalent rate of the ward was detected with X- and γ-ray detectors. After patient discharge, surface contamination of the ward was detected with α/β surface contamination meter. During patient hospitalization and on the day of discharge, air samples were collected from ¹³¹I treatment site and office area. The air samples were measured using a HPGe γ-ray spectrometer and the concentration of ¹³¹I in air was calculated. Results The ambient dose equivalent rate in the ward ranged from 0.15 to 0.46 μSv/h. Before ward cleaning, surface contamination ranged from 0.53 to 40.1 Bq/cm² and the highest value was recorded on the toilet. Within 4 h after administration, the concentrations of ¹³¹I in air in treatment site and the corridor of the office area were 1.74 Bq/m³ and 0.66 Bq/m³, respectively. The ventilation air flow rate in the treatment site was 0.50 m/s. Ventilation decreased the concentration of ¹³¹I in air by 29.7%, 79.7%, and 53.3% compared with the previous day during hospitalization and on the day of discharge. Conclusion The radiation of external exposure of ¹³¹I in the treatment site is low and the shielding is effective. Before ward cleaning, the surface contamination is lower than the required limits except for the toilet. Ventilation is the primary way to reduce the concentration of ¹³¹I in air.

ABSTRACT: Meningiomas are the most common primary intracranial neoplasm with diverse pathological types and complicated clinical manifestations. The fifth edition of the WHO Classification of Tumors of the Central Nervous System (WHO CNS5), published in 2021, introduces major changes that advance the role of molecular diagnostics in meningiomas. To follow the revision of WHO CNS5, this expert consensus statement was formed jointly by the Group of Neuro-Oncology, Society of Neurosurgery, Chinese Medical Association together with neuropathologists and evidence-based experts. The consensus provides reference points to integrate key biomarkers into stratification and clinical decision making for meningioma patients.

Objective To investigate the expression and clinical significance of TM9SF3 in lung adenocarcinoma (LUAD). Methods TCGA and GEPIA databases were used to screen the differentially-expressed TM9SF family molecules and analyze their effects on patient prognosis with LUAD. The expression and localization of TM9SF3 in LUAD patients were verified by a human proteomic mapping database, Western blot assay, and polymerase chain reaction assay. Herein, the GSEA was used for the signal pathway enrichment analysis of TM9SF3-related genes. Meanwhile, the TIMER database and CIBERSORT algorithm were used to analyze the correlation between differentially-expressed TM9SF3 and the degree of immune cell infiltration. Results The expression of TM9SF3 in LUAD was significantly increased and had a significant adverse effect on the prognosis of LUAD patients. In addition, immunoblotting and polymerase chain reaction confirmed that TM9SF3 was highly expressed in LUAD. Meanwhile, the genes related to TM9SF3 expression were mainly enriched in cell signaling pathways regulating immune cell activity. The expression of TM9SF3 was significantly correlated with the expression changes of six immune cells. Conclusion TM9SF3 is differentially expressed in LUAD and may be used as a potential prognostic marker for LUAD patients. TM9SF3 can also change the level of immune cell infiltration in LUAD patients and is expected to be a new potential target for LUAD immunotherapy.

Objective:To explore the association between weight status and early changes in blood pressure, cardiac structure and function in children at 4 years of age.Methods:A cross-sectional study of the relationship between weight status and cardiovascular parameters was performed on the platform of "Shanghai Birth Cohort" in Shanghai Xinhua Hospital between 2017 and 2020. Height, weight, blood pressure and echocardiography were measured in 1 477 children at 4 years of age. According to body mass index (BMI), participants were classified into five groups: underweight, lean, normal weight, overweight and obese. Blood pressure, cardiac structure and function indexes were compared among different groups using one-way ANOVA. The associations between blood pressure, cardiac structure and function and weight status in children were analyzed by linear regression models. Multivariate logistic regression models were used to analyze whether weight status was an independent risk factor for elevated blood pressure or left ventricular hypertrophy (LVH) in children.Results:A total of 1 477 children including 772 boys and 705 girls were included in this study. There were 115 overweight and obese boys (14.9%) and 68 overweight and obese girls (9.6%). The majority of children had normal weight (916 cases, 62.0%), followed by underweight (303 cases, 20.5%), overweight (130 cases, 8.8%), lean (75 cases, 5.1%), and obese (53 cases, 3.6%). With the increase of BMI, systolic blood pressure, diastolic blood pressure, left ventricular mass index (LVMI), left ventricular posterior wall thickness in systole, left ventricular posterior wall thickness in diastole, left ventricular diameter in end-systole, left ventricular diameter in end-diastole, interventricular septum thickness in systole and left ventricular ejection fraction showed significantly positive trend, and the differences among the groups were significant (F=31.73, 6.59, 14.22, 4.96, 3.01, 31.50, 39.79, 5.91, 3.09, all P<0.05). Multiple linear regression showed that overweight and obese were all positively associated with systolic blood pressure (β=5.2, 95% CI 3.6-6.8), LVMI (β=1.9, 95% CI 0.8-3.1), left ventricular diameter in end-systole (β=1.3, 95% CI 0.9-1.8), and left ventricular diameter in end-diastole (β=1.6, 95% CI 1.0-2.2). In the Logistic regression model, compared with normal weight children, overweight ( OR=2.37, 95% CI 1.37-4.41) and obese children ( OR=10.90, 95% CI 4.47-26.60) both had significantly increased risk of elevated blood pressure. However, the risk of LVH did not significantly increased. Conclusions:Overweight and obesity in 4-year-old children are associated with increased blood pressure, increased left ventricle diameter and LVMI. Overweight and obesity are independent risk factors for elevated blood pressure in children at 4 years of age.

Objective:To study the variation in activity in patient′s body with differentiated thyroid cancer (DTC) treated with 131I and external dose level, analyze the relationship between the both, and estimate the correction factor for the dose equivalent rate for the patients with residual activity of 400 MBq. Methods:A total of 43 DTC patients who received 131I therapy for the first time after total thyroidectomy were studied. The dose was 1 850-3 700 MBq and average dose was (2 405±777) MBq. The measurements of residual activity in patient′s body and of dose equivalent rate at 0.3, 1 and 3 m in front of the patients were performed at 2, 6, 20, 22, 24, 27, 30, 44, 46, 48, 54, 68 and 72 h after administration of 131I. Results:The residual activity in patient′s body after 131I therapy varied with time as a function of A= A0 (1.033 16e -0.062 4t+ 0.017 17). It can be estimated that the effective half-life of DTC patients treated with thyroid remnant 131I ablation therapy is 12.19 h. It needs only 26.4-38.9 h to reduce the internal activity to the 400 MBq. The functions of variation with time of normalized dose equivalent rate at 0.3, 1, and 3 m away from patients were: H· 0.3=127.220 7e -0.054 8t+ 3.765 71; H· 1=30.225 8e -0.064 4t+ 0.824 67; and H· 3=4.161 9e -0.061 5t+ 0.167 97, respectively. There was a positive correlation between residual activity and dose equivalent rate at 1 m ( r=0.982, P<0.05), and the function is H· 1=0.025 A+ 1.245. When residual activities in DTC patient′s body were 1 000, 700 and 400 MBq, the corresponding dose equivalent rates at 1 m from patients were 26.2, 18.7 and 11.2 μSv/h, respectively. The correction factors for dose equivalent rate at 0.3, 1 and 3 m from patients with 400 MBq were 0.25, 0.49 and 0.70, respectively. Conclusions:DTC patients with administration of 131I activity below 3 700 MBq need only to be hospitalized for two days to reach the discharge standards. When the residual activity in DTC patient′s body drops to 400 MBq, the dose equivalent rate at 1 m is far less than 25 μSv/h. Simply using the point source formula to estimate the dose equivalent rate around the patient will result in overestimation. Therefore, the correction factor used in the estimation of radiation doses to patients by using the formula needs to be further studied so as to make the model-based estimated result more consistent with the actual situation.

Objective:To evaluate the feasibility and clinical efficiency of robot-assisted laparoscopic radical prostatectomy (RARP) via extraperitoneal PORT-free single incision approach.Methods:The data of 33 patients with prostate cancer underwent the extraperitoneal PORT-free single incision RARP from November 2020 to January 2021 in Sichuan Provincial People's Hospital was retrospectively reviewed. The average age was 66.7 (58-78) years, the median PSA was 20.77 (2.89, 56.44) ng/m, and the mean Gleason score was 7.0 (6.0-9.0). The mean prostate volume was 48.4 (25.0-220.0) ml. Clinical stage: 32 cases was in cT 2a-2cN 0M 0, 1 case in cT 3aN 0M 0. 16 cases had a history of operation. All 33 operations were performed by the same operator. All operations were performed by extraperitoneal PORT-free single-incision approach. The surgical condition, postoperative complication, pathology, and follow-up results were observed. Results:In this study, 33 operations were successfully completed without conversion to open or additional single hole channel instruments. The average operation time was 61.3 (38.0-120.0) min, with the mean intraoperative bleeding volume of 72.2 (45.0-220.0) ml and the mean bladder neck urethral anastomosis time of 11.7 (8.5-15.7) min. The mean postoperative hospital stay was 7.9 (6.0-15.0) d, the mean postoperative indwelling time of urinary catheter was 6.8 (6.0-14.0) d, and the mean postoperative evacuation time was 1.0 (0.5-3.0) d. The average incision length was 5.2 (4.6-5.8) cm. There was no obvious complications. The postoperative pathological stage: 21 cases were in < pT 3a, 12 cases were in ≥ pT 3a, and 6 cases (18.8%) had positive resection margin. 29 cases (88.9%) acquired satisfactory urinary continence after operation, and the frequency of urinary pad use was ≤ 1 tablet/day. Conclusions:The extraperitoneal single-incision RARP surgical channel without PORT is safe and feasible with a satisfying cosmetic effect, which saves costs and requires less specific channel device. Simultaneously, the new approach has strong replicability, short-term tumor control and urinary control effect with rapid postoperative recovery. However, the sample size of this study is relatively small, which needs further research and demonstration
