ObjectiveTo explore the relationship between serum uric acid and prehypertension and the effects of age,obesity,fasting glucose and lipids in Chinese adults.Methods14,451 non-hypertensive cases from a community-based health examination survey in Xuzhou,Jiangsu province of China were enrolled in this study.Blood pressure,BMI,and determination of fasting glucose,lipids and serum uric acid were measured in all cases.ResultsThe odds ratios ( OR,95％ CI ) of prehypertension across increased serum uric acid after adjusting for age,sex were 1.0,1.20 ( 1.07 - 1.35 ),1.55 ( 1.36 - 1.76),1.82(1.60-2.09),2.33(2.03-2.67) (Pfor trend ＜0.01).The odds ratios were 1.0,1,04(0.92-1.18),1.21(1.06-1.38),1.26(1.09 - 1.45),1.36(1.17 - 1.58),( Pfor trend ＜0.01) after adjusting for age,sex,BMI,glucose,and lipids.In addition,fasting glucose significantly interacted with uric acid ( P for interaction ＜ 0.01 ).Conclusions Serum uric acid was associated with prehypertension,which might be an independent metabolic risk factor.Fasting glucose may reinforce the associations.

There is a broad and urgent need for the clinical application of anticancer nanomedicine in tumor therapy, but the complex biological barrier in solid tumors has always been the main obstacle to infiltrating nanomedicine into the tumor. The traditional design of nanomedicine based on enhanced permeability and retention (EPR) effect still has some limitations in tumor permeability, it is urgent to find other design theories. Therefore, this review summarizes two novel strategies, active transcytosis and immune cell-mediated tumor penetration, for promoting tumor penetration of anticancer nanomedicine.

OBJECTIVETo study the efficacy of levetiracetam (LEV) in the treatment of electrical status epilepticus during sleep (ESES) in children.

METHODSThe clinical data of 27 children who were newly diagnosed with ESES and treated with LEV between August 2009 and March 2011 and who were followed up for at least 6 months were retrospectively studied.

RESULTSThe onset age of the 27 children ranged from 9 months to 9 years and 7 months. Partial motion seizures were found in 81% of the children in the early stage. Twenty-three children received LEV treatment after ESES was definitely diagnosed. Of the 23 children, 19 were diagnosed as epilepsy syndrome of benign childhood epilepsy with centrotemporal spikes (BECT). The age of the patients at the beginning of LEV treatment ranged from 1 year and 8 months to 11 years and 9 months. The follow- up duration was 7 to 19 months. The effective rate of LEV for seizure control was 82% and for EEG recovery it was 78% (P<0.05). The other 4 children received LEV treatment before the occurrence of ESES. Seizure control and EEG recovery were noted in two of the 4 children.

CONCLUSIONSLEV treatment is efficacious, to some extent, for both seizure control and EEG recovery in children with ESES.

Objective To raise the awareness of childhood narcolepsy. Methods We analyzed the clinical data of 32 children with narcolepsy and review the literature. Results All the patients manifested as excessive daytime sleepiness with irresistible sleep attacks.Cataplexy appeared in 26 cases (81.3％),hypnagogic hallucination in 11 cases (34.4％),and sleep paralysis in merely 2 cases (6.25％).Daytime sleepiness was the first symptom in most cases.Common features included night sleep disorder,emotional disorder,excessive weight gain,and earlier puberty.Owing to the young age and short duration,a few children could have the false negative multiple sleep latency test (MSLT) results.Conclusion Excessive daytime sleepiness with irresistible sleep attacks and cataplexy are the typical clinical manifestations of Chinese narcoleptic children. A definite diagnosis is established on the comprehensive analysis of symptoms and assistant examination.

OBJECTIVETo investigate the distribution of congenital heart disease (CHD) aged 3 - 18 in several regions of Yunnan province.

METHODSCross-rectional studies were carried out among 48 638 children from Xishuangbanna, Dali, Baoshan Longling, Luxi Mangshi and Gejiu in Yunnan province with stratified, clustered sampling.

RESULTSThe overall morbidity of CHD was 5.08 per thousand with 5.09 per thousand in males and 5.07 per thousand in females. Morbidity rates in different regions were 2.75 per thousand in Xishuangbanna, 7.85 per thousand in Dali, 9.59 per thousand in Baoshan Long ling, 4.80 per thousand in Gejiu, 16.99 per thousand in Luxi Wuchalu. However, in the same area, rates were different among different residents:3.25 per thousand in Gejiu, and was 9.10 per thousand in Laochang stannum mine, 11.20 per thousand in Datunxuanchang; 5.74 per thousand at the city of Baoshan Longling, 11.35 per thousand at countryside; 4.90 per thousand at the city of Dali, 8.71 per thousand at countryside; 1.69 per thousand at the city of Xishuangbanna, 4.40 per thousand at country. Morbidity rates in different ethnic groups were as follows: 5.39 per thousand in Dai, 6.83 per thousand in Jinuo, 0 per thousand in Hani, 8.12 per thousand in Bai, 14.18 per thousand in Jingpo.

CONCLUSIONThere were significant regional and ethnic differences seen in Yunnan on the mobidity of CHD which was different from the domestic literature reported.

It has attracted much attention worldwide that the application of artificial intelligence (AI) in primary screening and clinical diagnosis and treatment of eye diseases. In recent years, this technology has also been widely used in various grass-roots eye disease management, effectively improving the current situation of weak eye disease diagnosis ability and shortage of human resources in primary medical institutions. At present, there is no reference standard or guideline for the management mode, implementation content and management method of vision health management based on this technology, which are in urgent need of standardization. The article described the work mode exploration of AI-assisted grass-roots visual health management in Shanghai and shared practical experience. The aim is to provide reference for other provinces in China to carry out relevant work.

Objective: To explore the heterogeneity and correlation of clinical phenotypes and genotypes in children with disorders of sex development (DSD). Methods: A retrospective study of 1 235 patients with clinically proposed DSD in 36 pediatric medical institutions across the country from January 2017 to May 2021. After capturing 277 DSD-related candidate genes, second-generation sequencing was performed to analyzed the heterogeneity and correlation combined with clinical phenotypes. Results: Among 1 235 children with clinically proposed DSD, 980 were males and 255 were females of social gender at the time of initial diagnosis with the age ranged from 1 day of age to 17.92 years. A total of 443 children with pathogenic variants were detected through molecular genetic studies, with a positive detection rate of 35.9%. The most common clinical phenotypes were micropenis (455 cases), hypospadias (321 cases), and cryptorchidism (172 cases) and common mutations detected were in SRD5A2 gene (80 cases), AR gene (53 cases) and CYP21A2 gene (44 cases). Among them, the SRD5A2 mutation is the most common in children with simple micropenis and simple hypospadias, while the AMH mutation is the most common in children with simple cryptorchidism. Conclusions: The SRD5A2 mutation is the most common genetic variant in Chinese children with DSD, and micropenis, cryptorchidism, and hypospadias are the most common clinical phenotypes. Molecular diagnosis can provide clues about the biological basis of DSD, and can also guide clinicians to perform specific clinical examinations. Target sequence capture probes and next-generation sequencing technology can provide effective and economical genetic diagnosis for children with DSD.
