Objective:A nomogram model for predicting double positivity of microvascular invasion (MVI) and vascular endothelial-to-mesenchymal transition (VETC) in patients with hepatocellular carcinoma (HCC) was constructed and its predictive performance was evaluated.Methods:A retrospective analysis was conducted on 326 HCC patients who were treated at the Third People's Hospital of Nantong and the First Affiliated Hospital of Soochow University from January 2013 to June 2023, including 240 males and 86 females, with an average age of (58.7±9.0) years. The 326 patients were randomly divided into a training set ( n=228) and a test set ( n=98) at a ratio of 7: 3 using the random number table method. The training set was divided into a double-positive group ( n=54) and a control group ( n=174) based on whether the HCC patients were double positive for MVI and VETC. Univariate and multivariate logistic regression analyses were performed to identify the influencing factors of double positivity of microvascular invasion in HCC patients, and a nomogram for predicting double positivity of microvascular invasion patterns was constructed based on the multivariate. The predictive performance and clinical net benefit of the nomogram were evaluated using the receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis. Results:There were statistically significant differences in alpha-fetoprotein, gamma-glutamyl transferase, and phosphatidylinositol proteoglycan between the two groups (all P<0.05). Multivariate logistic regression analysis showed that LI-RADS category ( OR=8.58, 95% CI: 1.87-39.38), intratumoral hemorrhage ( OR=2.16, 95% CI: 1.14-4.07), and intratumoral arteries ( OR=2.59, 95% CI: 1.19-5.64) were all influencing factors of double positivity of microvascular invasion patterns in HCC patients (all P<0.05). Based on the multivariate results, a nomogram was constructed. In the training set, the area under the ROC curve for predicting double positivity of microvascular invasion patterns in HCC patients was 0.769 (95% CI: 0.720-0.814). In the test set, the area under the ROC curve for predicting double positivity of microvascular invasion patterns in HCC patients was 0.756 (95% CI: 0.622-0.850). The calibration curve showed a good fit between the predicted model and the ideal curve. Decision curve analysis showed that the clinical applicability was good when the threshold was 0.01-0.80 in the training set and 0.01-0.65 in the test set. Conclusion:The nomogram model based on LI-RADS category, intratumoral hemorrhage, and intratumoral arteries can effectively predict double positivity of microvascular invasion patterns in HCC patients and has good clinical applicability.

Objective:To investigate the correlation between macular cherry red spot (CS) and severity of neurological manifestations in Chinese children with sialidosis (SD) type I.Methods:A evidence-based medical study. "China", "Sialidosis" and "Sialidoses" were used as Chinese and English search terms. The literature was searched in CNKI, Wanfang and PubMed. The cases were all from China and matched the diagnostic criteria. According to the presence or absence of CS in the fundus, the SD children were divided into a group with CS (+) and a group without CS (-), and the correlation between the occurrence of ocular CS and neurological manifestations was compared with meta-analysis by RevMan 5.3 software.Results:Sixty-eight studies were initially retrieved according to the search strategy, and 17 studies were finally included, and 5 studies with CS+ and CS- were meta-analyzed. Among the 43 patients, 28 were male and 15 were female, with a median age of 12 years. Visual impairment was observed in 37 cases (90.2%, 37/41, 2 cases not recorded), and CS was present in 24 cases (55.8%, 24/43). The most common neurological manifestation was myoclonus (97.7%, 42/43), followed by cerebellar ataxia (95.1%, 39/41, 2 cases not recorded) and seizures (91.4%, 32/35, 8 cases not recorded). Pathogenic NEU1 gene mutations were detected in 42 cases and one case was undocumented. The incidence of seizure in group CS+ (100%, 20/20) was higher than that in group CS- (80%, 12/15). Meta-analysis showed that there was no statistically significant difference between the incidence of myoclonus or ataxia [relative risk ( RR)=1.13, 95% confidence interval ( CI) 0.79-1.63, P=0.49] and seizure ( RR=1.13, 95% CI 0.84-2.06, P=0.24) among the children in the CS+ and CS- groups. Conclusions:The incidence of ocular CS in Chinese children with type I SD was 55.8%. There was no correlation with neurological manifestations, however the incidence of seizure was significantly higher in patients with CS than in others without CS.

Objective:To observe the clinical features of eyes in children with methylmalonic acidemia (MMA).Methods:A retrospective clinical case study. From June 2019 to June 2022, 13 children with MMA visited on the Department of Ophthalmology of Henan Children's Hospital were included in the study. The anterior segment and fundus were examined under surface or general anesthesia. Best corrected visual acuity (BCVA) and refraction were performed in 9 cases; fluorescein fundus angiography (FFA) was performed in 3 cases; flash electroretinogram (FERG) was performed in 6 cases; flash visual evoked potential (FVEP) was detected in 6 cases; optical coherence tomography (OCT) was performed in 3 cases.Results:Among the 13 pediatric patients with methylmalonic acidemia, 6 cases were male and 7 cases were female. The average age at first visit was 45 months. All cases suffered from hyperhomocysteinemia; 9 cases were with epilepsy; 2 cases were with infantile spasms; 11 cases were with stunting, 13 cases were with repeated pulmonary infection during growth period; 4 cases were with hydrocephalus; 1 cases was with hypertension and renal insufficiency. Genetic dectection results of 8 cases were recorded, MMACHC:c.609G>A:p.W203* mutation site was found in all cases. One case was accompanied by corneal ulcer. There were 10 cases with nystagmus, 4 cases with macular degeneration, 3 cases with hyperopic refractive error and esotropia. Nine cases underwent BCVA examination, BCVA was light perception-0.6. In OCT, 2 cases of 3 cases showed retinal thinning and photoreceptor cell layer atrophy in the macular area. In FFA, 2 cases of 3 cases showed circular transparent fluorescence in the macular area. Five cases of 6 cases who with FVEP had different degrees of P100 peak time delay and decreased amplitude, and 4 cases of 6 cases with FERG had decrease of a and b wave in light and dark adaptation. Conclusions:The clinical phenotypes of eyes in children with MMA are various and the severity was different; most of them are accompanied by nystagmus, and the fundus lesions are common in the characteristic bovine eye like macular region. Those with macular disease have severe visual impairment.

Objective:To observe and analyze the ocular clinical features and pathogenic genes of Alstr?m syndrome (ALMS).Methods:A retrospective clinical study. From October 2020 to July 2022, 3 patients and 5 normal family members from 2 families affected with ALMS who visited in the Ophthalmology Department of Henan Children's Hospital were enrolled in the study. These 2 families were without blood relationship. The medical history and family history were inquired. Best corrected visual acuity (BCVA), fundus color photography, full-field electroretinogram (ERG), frequency domain optical coherence tomography (OCT) and systemic examination were performed. 3 ml peripheral venous blood of patients and their family members were collected, and the whole genomic DNA was extracted. The second generation sequencing analysis was performed on these members. The suspected pathogenic mutation sites were verified by Sanger, and the pathogenicity of the gene mutation sites were determined by bioinformatics analysis.Results:Three patients from two families all developed nystagmus and photophobia in infancy. In the family 1, the BCVA of both eyes of the proband was no light perception. The fundus examination revealed vascular attenuation and retinal pigment abnormality. OCT showed retinal thinning, loss of photoreceptor layer and atrophy of the retinal pigment epithelium layer. ERG examination showed extinguished. The BCVA of the proband’s younger brother was 0.04 in the right eye and 0.02 in the left eye. The fundus examination revealed vascular attenuation but the pigment distribution was roughly normal. OCT showed blurred photoreceptor layers in both eyes. ERG examination showed extinguished. Two patients developed sensorineural deafness, obesity, acanthosis nigricans, insulin resistance/diabetes, and abnormal liver function. In addition, the proband also had left heart enlargement, hyperlipidemia and abnormal kidney function. The results of genetic testing showed that the proband and his younger brother had compound heterozygous mutations in exon 8 (c.1894C>T/p.Gln632*, M1) and exon 10 (c.9148_9149delCT/p.Leu 3050 Leufs*9, M2) of ALMS1, which were both known mutations. The father of the proband was a carrier of M1 and the mother of the proband was a carrier of M2. The proband of the family 2 had a normal fundus at 23 months old. The amplitude of ERG b wave under the stimulation of the dark adaptation 0.01 and a, b wave under the stimulation of dark adaptation 0.3 were all mild reduced. The amplitude of ERG a, b wave under the stimulation of the light adaptation 0.3 was severity decreased. At 4 years old, the BCVA was 0.01 in the right eye and 0.05 in the left eye. The fundus examination revealed vascular attenuation and bilateral blunted foveal reflex. In addition to severely diminished of a, b wave under the stimulation of dark adaptation 0.3, the rest showed extinguished. There were no systemic abnormalities. The results of genetic testing showed that the proband had compound heterozygous mutations in exon 11 (c.9627delT/p.Pro3210Glnfs*22, M3) and exon 5 (c.1089delT/p.Asp364Ilefs*13, M4) of ALMS1, which were both novel mutations. The father of the proband was a carrier of M3 and the mother of the proband was a carrier of M4. Conclusions:Nystagmus and photophobia are often the first clinical manifestations of ALMS. In the early stage, the fundus can be basically normal. As the disease progresses, the fundus examination reveals vascular attenuation and retinal pigment abnormality, and the reflection of the fovea is unclear. OCT shows the photoreceptor cell layers are blurred or even lost. The final ERG is extinguished. M1, M2, and M3, M4 compound heterozygous mutations may be the pathogeny for family 1 and family 2, respectively.

Objective To identify the effectiveness of physical therapy on neuromuscular control dysfunction of chronic ankle instability (CAI). Methods CAI physiotherapy-related systematic reviews, meta-analysis, randomized controlled studies and case-controlled studies were systematically searched in PubMed, Web of Science, Cochrane, PEDro, EBSCO and CNKI from October 1st, 2010 to October 1st, 2020. After quality assessment, the research evidence regarding certain intervention was then graded according to the Oxford Center for Evidence-based Medicine. Results A total of 20 articles were included. Intervention based on unstable plane exercise training could significantly improve lower limb balance control ability (Ⅰ A) and muscle strength (Ⅱ A) for CAI patients. The efficiency of exercise-based intervention could be further raised (Ⅱ C) with the aid of external equipment, but either the benefits in muscle reaction (Ⅲ C) or proprioception (Ⅱ D) was limited. Six sessions or more of manual therapy could be used to enhance the balance ability of the lower limbs (Ⅱ B), while taping failed to provide improvements in ankle proprioception in short period or immediately (Ⅰ A). Conclusion Unstable plane training-based therapeutic exercise and manual therapy could effectively enhance the neuromuscular control with high-quality evidence supporting, which can be primary interventions for CAI patients. Meanwhile, taping and other external devices could be used as adjunct methods to improve the efficiency of physiotherapy program, while there is currently no evidence to support the application of modality treatment in neuromuscular control of CAI.

Group A Streptococcus (GAS) is a very important pathogen, especially for children.On a global scale, GAS is an important cause of morbidity and mortality.But the burden of disease caused by GAS is still unknown in China and also has not obtained enough attention.For this purpose, the expert consensus is comprehensively described in diagnosis, treatment and prevention of GAS diseases in children, covering related aspects of pneumology, infectiology, immunology, microbiology, cardiology, nephrology, critical care medicine and preventive medicine.Accordingly, the consensus document was intended to improve management strategies of GAS disease in Chinese children.

Objective:To observe the ocular clinical features of infantile cytomegalovirus (CMV) infection.Methods:A retrospective clinical study. From March 2019 to July 2021, 876 eyes of 438 children with CMV infection who visited Department of Ophthalmology of Henan Provincial Children's Hospital were included in the study. Among them, there were 254 males and 184 females; the age ranged from 3 days to 11 months; the gestational weeks were 28 to 42 weeks; the birth weight was 1 120 to 8 900 g. There were 384 and 54 full-term and premature infants, respectively. Fundus examination was performed in 385 cases (770 eyes) after medical consultation; 53 cases (106 eyes) of premature infants were routinely screened. CMV retinitis (CMVR) was divided into granular type and fulminant type. Patients with CMV-related diseases with moderate to severe symptoms were given intravenous drip and/or oral ganciclovir; patients with severe fundus vasculitis were combined with intravitreal injection of ganciclovir. The follow-up period was from 4 to 28 months, and the characteristics of eye lesions, systemic comorbid diseases and treatment outcomes were observed.Results:There were 516 eyes of 258 cases with normal fundus (58.9%, 258/438); 291 eyes of 180 cases with CMVR (41.1%, 180/438), of which binocular and monocular were 111 (61.7%, 111/180) and 69 (38.3%, 69/180) cases. Among the 291 eyes of CMVR, 281 eyes (96.6%, 281/291) of granular type; yellow-white point-like opacity and/or retinal hemorrhage; 10 eyes (3.4%, 10/291) of fulminant type; fundus Showed a typical "cheese ketchup-like" and vascular white sheath-like changes. Among the 180 children with CMVR, 72 patients (118 eyes) were given systemic intravenous drip and/or oral ganciclovir; 5 patients (10 eyes) were given intravitreal ganciclovir, all of which were fulminant CMVR. At the last follow-up, fundus lesions regressed significantly in 100 eyes of 61 cases; 18 eyes of 11 cases had old lesions or uneven retinal pigment; 108 cases were not treated.Conclusion:The most common fundus manifestation of CMV infection in infants is granular retinitis, and fulminant retinitis is more severe, and the lesions can be significantly regressed after timely antiviral treatment.

Objective:To observe the ocular clinical features and efficacy of young infants with incontinentia pigmenti (IP).Methods:A retrospective study. Clinical data of 18 young infants with IP aged 0-3 months in the Department of Ophthalmology of Henan Children's Hospital from October 2017 to February 2019 were collected in this study. All patients were underwent fundus examination under topical anesthesia or general anesthesia. Among them, 9 cases were underwent genetic testing. Patients were determined whether to treated with retinal laser photocoagulation (LIO) or intravitreal conbercept (IVC, 0.25 mg/0.025 ml) according to the condition of eyes. The followed-up time ranged from 4months to 43 months. The ocular clinical features and treatment were observed.Results:There were 1 male and 17 females of the 18 patients. The age of first visit were 1.2±1.0 months (2 d-3 months). All cases had typical skin lesions, 4 cases had neurological symptoms, 10 cases had tooth abnormalities, and 4 cases had cicatricial alopecia. Among the 9 cases that were underwent genetic testing, 5 cases were deleted in exons 4-10 of the IKBKG gene and 1 case were a heterozygous mutation c.1124delT in exon 9 of the IKBKG gene. Among the 36 eyes, 21 eyes of 13 cases with incontinentia pigmenti-associated ocular diseases were all retinopathy (58.3%,21/36). Retinopathy of 9 cases were asymmetrical (69.2%,9/13). Among the 21 eyes, 3 eyes were simple retinal pigment abnormalities (14.3%,3/21) and 18 cases had retinal vascular lesion (85.7%, 18/21). Among the 36 eyes, 8 eyes were treated; 4 eyes were underwent LIO; 3 eyes were treated with IVC; 1 eye was treated with LIO combined with IVC. They were all improved significantly after the operation without serious complications. 1 eye with retinal detachment did not undergo surgical treatment due to guardian reasons. Perceptual exotropia and eyeball atrophy was found during the follow-up. Conclusions:The onset of IP-related ocular anomalies is early. The early anomalies were mainly retinal vascular abnormalities. Treatment in early time is effective.
