Objective: To investigate the molecular transmission network characteristics of HIV-1 among men who have sex with men (MSM) in Shaoxing City, Zhejiang Province, so as to provide insights into AIDS prevention and control among MSM. Methods: Newly reported HIV/AIDS cases among MSM in Shaoxing City were selected from January 2021 to September 2023. Plasma samples before the antiviral treatment were collected. The HIV-1 pol gene was amplified using reverse transcription PCR and nested PCR to construct phylogenetic trees for gene subtype analysis. The HIV-TRACE method was used to construct a molecular transmission network with a genetic distance of 1.5% to analyze clustering and the characteristics of cases within molecular clusters. Results: A total of 216 HIV/AIDS cases among MSM were included, and 179 qualified sequences were obtained. The predominant HIV-1 subtypes were CRF07_BC and CRF01_AE, with 95 and 66 cases, respectively. At 1.5% genetic distance, 20 molecular clusters were formed, with 61 nodes and 58 edges. A total of 61 sequences were connected to the transmission network (34.08%). HIV/AIDS cases among MSM from all the counties (cities, districts) in Shaoxing City were included in the network. There was the largest molecular cluster with ≥10 nodes, involving 12 cases from five counties (cities, districts), 3 medium-sized molecular clusters with 4 to 5 nodes, and the 16 small-sized molecular clusters with 2 or 3 nodes. Seven cases with high risk of transmission, each with ≥4 edges, were all CRF07_BC subtypes. Among them, two cases were from the large molecular cluster, and five cases were from the same molecular cluster composed of cases from Shengzhou City and Xinchang County. Conclusions The predominant HIV-1 subtypes among MSM in Shaoxing City were CRF07_BC and CRF01_AE. There was cross-regional HIV transmission, and potential transmission risk might exist in Shengzhou City and Xinchang County.

Objective:To investigate the repeatability of corneal topographic parameters with the Pentacam HR in patients with keratoconus of different severity.Methods:A diagnostic test study was performed.A total of 120 eyes from 98 patients with subclinical keratoconus or keratoconus were enrolled at Henan Eye Hospital from January 2019 to March 2022.The patients were divided into subclinical keratoconus group, mild keratoconus group, moderate keratoconus group and severe keratoconus group, with 30 eyes in each group.An additional 30 eyes of 30 subjects undergoing refractive surgery were selected as a control group.Three consecutive Pentacam HR measurements were performed by the same clinician.The recordings included a total of 53 parameters in anterior corneal surface, posterior corneal surface, thickness, composite index, and corneal densitometry.The within-subject standard deviation (Sw), repeatability limit ( r) and tolerance index (TI) were calculated to evaluate the repeatability of the parameters between different groups.This study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2019[5]).All subjects were informed of the purpose and significance of the study and signed an informed consent form before enrollment. Results:Compared with the control group, the TI of the subclinical, mild, moderate and severe keratoconus groups were 54.71%(29/53), 66.04%(35/53), 90.57%(48/53) and 94.34%(50/53), respectively, higher than 0.31.The steep keratometry (Ks), the maximum keratometry (Kmax) of the anterior corneal surface, the anterior corneal radius of curvature, the flat keratometry (Kf) of the posterior corneal surface, the posterior corneal radius of curvature (PRC), the thinnest corneal thickness (TCT), the average densitometry for the anterior 120 μm in the 0-2 mm area (A.0-2 mm), average densitometry for the anterior 120 μm in the 2-6 mm area (A.2-6 mm), average densitometry for the central tissue in the 0-2 mm area (C.2-6 mm), average densitometry for the total cornea in the 0-2 mm area (T.0-2 mm) and average densitometry for the total cornea in the 2-6 mm area (T.2-6 mm) showed good repeatability in the subclinical and mild keratoconus groups (TI<0.31).Kmax Zonal Mean 3 mm, posterior corneal surface mean keratometry, central keratoconus index showed good repeatability in subclinical, mild and moderate keratoconus groups.Kmax Zonal Mean 4 mm and Kmax Zonal Mean 5 mm showed good repeatability in all groups (TI<0.31).Conclusions:For patients with subclinical and mild keratoconus, Kf of the posterior corneal surface, PRC and TCT are recommended to monitor disease progression.To monitor the condition of patients with moderate and severe keratoconus, we may focus on the detection of Kmax Zonal Mean 4 mm and Kmax Zonal Mean 5 mm.

Objective:To analyze the clinical efficacy and prognostic factors of comprehensive treatment for atypical teratoid / rhabdomyoma tumor (AT/RT).Methods:Clinical data of children diagnosed with AT/RT who underwent radiotherapy in Department of Oncology of Xinhua Hospital affiliated to Shanghai Jiao Tong University School of Medicine from November 2012 to September 2022 were retrospectively analyzed. Pearson Chi-square test or continuous-corrected Chi-square test or Fisher's exact probability method were used for inter-group comparison of categorical variables. Independent sample t-test or Wilcoxon rank-sum test were used for inter-group comparison of continuous variables. Kaplan-Meier method was used to calculate the 1-year and 2-year overall survival (OS) rate and progression free survival (PFS) rate. Univariate and multivariate Cox regression analyses were employed to determine relevant prognostic factors. Results:A total of 45 patients were included, with a male/female ratio of 1.65:1, including 27 children aged ≥3 years old. All patients received surgery and radiotherapy in which 39 patients received chemotherapy, 41 craniospinal irradiation (CSI), and 4 whole brain or focal radiation therapy. The median follow-up was 28 (13.5, 49) months. A total of 14 patients died after comprehensive treatment. The 1-year OS rate was 80.0% and the PFS rate was 71.1%. The 2-year OS rate was 75.5% and the PFS rate was 65.7%. Survival prognostic analysis showed negative imaging assessment after radiotherapy ( HR=0.087, 95% CI: 0.011-0.697, P=0.022) was a favorable factor for PFS. The primary tumor<4.8 cm ( HR=0.221, 95% CI: 0.052-0.935, P=0.040) and CSI ( HR=0.085, 95% CI: 0.011-0.651, P=0.018) were favorable factors for OS. In subgroup analysis, CSI also improved OS in children aged ≥3 years ( HR=0.014, 95% CI: 0-0.470, P=0.017), but there was no significant difference in PFS. In children without cerebrospinal fluid dissemination, negative radiographic results after radiotherapy ( HR=0.066, 95% CI: 0.009-0.481, P=0.007; HR=0.076, 95% CI: 0.008-0.695, P=0.024, respectively) and CSI (HR=0.105, 95% CI: 0.012-0.937, P=0.044; HR=0.054, 95% CI: 0.005-0.629, P=0.020, respectively) were favorable factors for PFS and OS in children, and the primary tumor<4.8 cm also suggested a longer OS ( HR=0.094, 95% CI: 0.013-0.690, P=0.020). Conclusions:Comprehensive treatment including radiotherapy improves clinical prognosis of children with AT/RT. Our study shows that negative imaging results after radiotherapy are associated with PFS improvement. The primary tumor<4.8 cm and CSI are favorable factors for OS. CSI is also a significantly positive prognostic factor in children aged ≥3 years and those without cerebrospinal fluid dissemination.

Objective:To investigate the clinical characteristics of patients with keratoconus, and to explore the factors influencing keratoconus severity.Methods:A cross-sectional study was performed.A total of 908 patients (1 476 eyes) with primary keratoconus were enrolled in Henan Eye Hospital from January 2019 to December 2021.The medical history data of patients were collected by face-to-face questionnaire survey.Refractive parameters were measured by subjective optometry.Intraocular pressure (IOP) was measured by a non-contact tonometer, and corrected IOP was calculated by Dresden formula.Corneal topography parameters was obtained using Pentacam HR.The subgroup analysis of clinical characteristics of all patients was performed by age (<21 years, 21~<31 years, ≥31 years) and gender.Disease severity was graded based on steep keratometry (Ks), namely mild (Ks<48 D), moderate (48 D≤Ks<55 D) and severe (Ks≥55 D). The influencing factors of disease severity in keratoconus were analyzed by ordered Logistic regression.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Henan Eye Hospital (No.HNEECKY-2019[5]). All subjects or guardians were informed of the purpose and significance of the study and written informed consent was obtained.Results:Of the 908 patients, 622 were with bilateral keratoconus and 286 were with unilateral keratoconus.The median age of onset was 20(17, 26) years, and the median age of diagnosis was 21(18, 27) years.The ratio of males to females was 3.05∶1.There were 9.80%(89/908) of the patients having a history of allergy, 25.55%(232/908) having a history of other systemic diseases, and 1.98%(18/908) having a family history of keratoconus.Of the 1 476 affected eyes, 27.57%(407/1 476) were diagnosed as severe keratoconus, and 61.94%(568/917) had a history of eye rubbing.The medians of sphericity, cylindricity, IOP, corrected IOP, Ks, thinnest corneal thickness (TCT), anterior corneal surface elevation (AE) and posterior corneal surface elevation (PE) were -4.00(-7.00, -1.75)D, -3.50(-6.00, -1.50)D, 12.00(10.30, 13.80)mmHg, 15.40(13.60, 17.00)mmHg, 49.85(46.40, 54.90)D, 460.00(425.00, 490.00)μm, 21.00(13.00, 34.75)μm, 51.00(33.00, 75.00)μm, respectively.The spherical refraction, IOP and corrected IOP were lower and the cylindrical refraction was higher in patients at age <21 years than in patients at age 21~<31 years, and the TCT of patients at age <21 years was higher than that at age ≥31 years, and the differences were statistically significant (all at P<0.05). Compared with female patients, male patients had younger onset age, lower spherical refraction, IOP and corrected IOP, as well as higher cylindrical refraction, AE and PE, showing statistically significant differences (all at P<0.05). The spherical refraction and IOP of male patients were lower than those of female patients at age <21 years, and the cylindrical refraction was higher in males than in females among the patients at age 21~<31 years, and the differences were statistically significant (both at P<0.05). Among the patients with onset age <21 years and diagnosis age <21 years, the ratio of males to females in patients with severe keratoconus was higher than those with mild and moderate disease, and the difference was statistically significant (both at P<0.05). Older age of onset was a protective factor for disease severity in keratoconus (odds ratio=0.981, 95% confidence interval: 0.963~0.999). Conclusions:The younger the onset age of keratoconus patients, the more severe the disease.Among the patients with severe keratoconus, there were more male patients, and males have a younger onset age and severer conditions.It is suggested that early screening of keratoconus in children and adolescents should be strengthened in clinical work, and more active prevention and treatment measures should be taken for younger patients, especially males.

Objective:To investigate the clinic opathological features, treatment and prognosis of children newly diagnosed with ependymoma.Methods:Clinical data of 127 pediatric ependymoma (EPN) patients (0-16 years old) treated with tumor resection and postoperative radiotherapy at Xinhua Hospital Affiliated to Shanghai Jiao Tong University between 2001 and 2021 were retrospectively analyzed. Among them, 53 children were female and 74 were male. Local control (LR), event-free survival (EFS) and overall survival (OS) rates were analyzed by Kaplan-Meier method. The relationship between clinic opathological factors and clinical prognosis, and the effect of treatment on clinical prognosis of patients were analyzed by Cox proportional hazards model.Results:At a median follow-up time of 29 months (3-251 months), the 3-year OS and EFS rates were 89.5% and 71.5%, respectively. For patients undergoing incomplete resection followed by postoperative adjuvant radiotherapy, the 3-year LR, OS and EFS rates were 78.3%, 65.8% and 85.7%, respectively. A total of 43 children were aged <3 years old when diagnosed and 84 aged ≥3 years old. The interval time between surgery and radiotherapy in children aged <3 years old was 91 d, and 35.5 d in those aged ≥3 years old ( P<0.001). For patients <3 years old, the median EFS was 90 months when initiating radiotherapy within ≤70 d after surgery, compared to 43 months for those who initiated radiotherapy at >70 d after surgery ( P=0.053). According to fifth edition of the WHO classification of tumors of the central nervous system (WHO CNS5), 39 children were classified as posterior fossa ependymoma group A (PFA group). The OS and EFS rates in the PFA group were significantly less than those in other groups (3-year OS rate were 69.2% vs. 94.6%, P<0.001; 3-year EFS rate were 46.9% vs. 79.1%, P<0.001). In the PFA group, 12 patients received postoperative adjuvant chemotherapy, 14 did not receive chemotherapy, and whether chemotherapy was given was unknown in 13 cases. No significant differences were observed in OS and EFS between patients treated with and without chemotherapy ( P=0.260, P=0.730). Univariate Cox analysis showed that tumor location and WHO CNS5 molecular classification were significantly associated with EFS, and WHO CNS5 molecular classification was significantly correlated with OS. Multivariate Cox analysis showed that tumor location in the posterior fossa was an independent risk factor for EFS ( HR=2.72, 95% CI=1.1~6.71, P=0.03). Conclusions:Patients newly diagnosed with pediatric ependymoma can obtain favorable survival after surgery combined with postoperative adjuvant radiotherapy. Patients with residual tumors can achieve favorable LC and survival after postoperative adjuvant radiotherapy. Delaying of radiotherapy tends to lead to poor survival for patients aged <3 years old when diagnosed. Children in the PFA group obtain worse prognosis compared to their counterparts in other groups. The tumor location in the posterior fossa is an independent risk factor for pediatric ependymoma.

ObjectiveTo explore the characteristics of fine motor skills of school-age children with attention deficit hyperactivity disorder (ADHD) in different sexes. MethodsFrom April, 2021 to April, 2023, 66 ADHD children from grades one to four in Beijing Haidian Wanquan Primary School were screened by psychiatrists, and other 69 ADHD children were recruited from hospitals and patient groups of WeChat, accounting to 135 ADHD children. Meanwhile, a total of 135 typically developed (TD) children matched with sex and age (< 0.5 year) were recruited from the same primary school as controls. They were assessed with Movement Assessment Battery for Children (MABC-2) four subtests of manual dexterit. ResultsAfter controlling age, the subtest scores and the total score of fine motor of MABC-2 were less in ADHD boys and girls than in the TD boys and girls (P < 0.05). The main effect of sex was significant on the subtest scores and the total score of fine motor for ADHD children (F > 5.133, P < 0.05), and they were less in the boy than in the girls (P < 0.05). ConclusionThe development of fine motor delays in school-aged ADHD children, especially for the boys.
