ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome）. MethodsThrough a multi-center randomized controlled methodology design，confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals，such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days，and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale （CARIFS） and the incidence of complications，severe cases， and critical cases. Follow-up observation was conducted on the day of enrollment，48 hours after medication，72 hours after medication， and （6+1） d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group （90 cases） or the control group （90 cases）. All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was （5.29±1.25） d，and that in the control group was （5.40±1.68） d，without a statistically significant difference. After five days of intervention，52 cases in the experimental group and 51 cases in the control group converted to negative，without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention，there were statistically significant differences between the experimental group and the control group in three dimensions， including headache，muscle soreness， and the need for extra care （P<0.05）. On the （6+1） days after the intervention，the differences in both the experimental group and the control group were statistically significant in 10 dimensions， including sore throat，bad sleep，uncomfortable feeling，poor spirit and fatigue，crying more than usual，the need for extra care，symptom，function，influence on parents，and total score （P<0.05）. The comparison results within the group in the dimensional scores of symptom， function， and influence on parents，as well as the CARIFS total score showed that with the delay of follow-up time，scores of both groups decreased significantly，with a statistically significant difference （P<0.01）. Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention，the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up，the mean score of the experimental group was lower than that of the control group，with no statistically significant difference. In terms of the incidence of complications，severe cases， and critical cases， there were no complications，severe cases， and critical cases in the two groups，without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome） are not inferior to Oseltamivir Phosphate granules， and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.

AIM: To observe the clinical outcomes of Phorcides analytic engine-assisted topography-guided personalized laser assisted in situ keratomileusis(LASIK)for the treatment of myopia and astigmatism in virgin eyes with the refractive astigmatism significantly deviating from corneal topography.METHODS: Retrospective clinical study. A total of 32 cases(42 eyes)with myopia and astigmatism that received corneal topography-guided personalized LASIK in the Ophthalmology Refractive Surgery Center of the First Affiliated Hospital of Xi'an Jiaotong University from December 2019 to March 2021 were selected. The uncorrected distance visual acuity(UDVA), best corrected distance visual acuity(CDVA), refractive state and aberrations before and at 6 mo after surgery were recorded.RESULTS: There were 15 males and 17 females, with an age of 23.00(18.00, 29.25)years old; preoperative sphere was -5.75(-6.25, -4.00)D, and cylinder was -0.75(-1.38, -0.25)D. At 6 mo postoperatively, the UDVA exceeded the preoperative CDVA in 19 eyes(45%). The spherical equivalent(SEQ)of all eyes(100%)was -0.50 to +0.50 D at 6 mo postoperatively, and the postoperative SEQ of 23 eyes(55%)was -0.13 to +0.13 D. There were 33 eyes(79%)had a postoperative astigmatism ≤ 0.25 D, the target-induced astigmatism(TIA)was 0.94±0.96 D, and the surgically induced astigmatism(SIA)was 0.94±0.86 D, with no statistical significance between TIA and SIA(P>0.05). The astigmatism axial deviation ranged from -5° to +5° in 33 eyes(79%)at 6 mo postoperatively. Compared to pre-operation, the total higher-order aberrations and spherical aberrations within the central 6 mm diameter of the anterior corneal surface increased at 6 mo postoperatively(Z=-3.778, P<0.001; Z=-4.929, P<0.001); the postoperative coma aberrations had no change(Z=-1.763, P=0.078); the postoperative trefoil aberrations decreased(Z=-2.490, P=0.013). Compared to pre-operation, the Strehl ratio of the anterior corneal surface increased significantly at 6 mo after surgeries(t=-5.401, P=0.013).CONCLUSION: Using the Phorcides analytic engine to assist topography-guided personalized LASIK for the treatment of myopia and astigmatism in virgin eyes with the refractive astigmatism significantly deviating from topography-measured astigmatism can achieve good therapeutic effects. Postoperative UDVA exceeded preoperative CDVA in nearly half of the eyes, and the quality of postoperative corneal imaging was improved.

Objective To evaluate the diagnostic value of transrectal contrast-enhanced ultrasound (CEUS) for rectal cancer with intestinal stenosis caused by tumors. Methods Forty-nine patients with rectal cancer underwent transrectal CEUS and magnetic resonance imaging (MRI) before surgery.Intraoperative tumor localization and postoperative pathological results were taken as the gold standard for diagnosis.The differences in T stage,localization,and tumor length of rectal cancer were compared between the two methods. Results The total accuracy rates of transrectal CEUS and MRI in diagnosing T stage were 75.5% (36/49) and 67.3% (33/49),which had no significant difference (χ²=0.8,P=0.371).The total accuracy rates of transrectal CEUS and MRI in judging tumor localization were 79.5% (39/49) and 77.5% (38/49),which had no significant difference (χ²=0.061,P=0.806).The measurement results of tumor length in pathological examination had no significant difference from the transrectal CEUS results (t=1.42,P=0.162) but a significant difference from the MRI results (t=3.38,P=0.001).Furthermore,transrectal CEUS detected 8 (16.3%) cases of colonic polyps among the 49 patients,while MRI did not detect colon lesions. Conclusions Transrectal CEUS has good consistency with MRI in T staging and localization judgement of rectal cancer with intestinal stenosis,and this method can more accurately evaluate the tumor length and simultaneously evaluate whether there is a lesion in the entire colon at the proximal end of stenosis.It can be used as a supplementary examination before rectal cancer treatment in clinical practice.

Objective:To explore the characteristics of social skills and problem behaviors of children and adolescents with autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD), as well as the association with core symptoms.Methods:A total of 409 patients aged 5-18 years old with ASD or ADHD in the outpatient department of Nanjing Brain Hospital from 2023 to 2024, and 344 children and adolescents with typical development(TD) were recruited.All participants were matched in a ratio of 1∶1∶1 (ASD∶ADHD∶TD) according to gender and age, and 97 participants were included in each group for analysis.The Chinese version of the social skills improvement system rating scales(SSIS-RS-C) was used to evaluate social skills and problem behaviors, and autistic child behavior checklist(ABC), childhood autism rating scale(CARS), the Chinese version of the social communication questionnaire(SCQ) and the Chinese version of Swanson, Nolan, and Pelham, version Ⅳ scale-parent form(SNAP-Ⅳ) were used to evaluate the core symptoms of ASD and ADHD, respectively. SPSS 26.0 software was used to perform variance, Chi-square test, Spearman correlation analysis and multivariate Logistic regression analysis.Results:The social skills score of ASD group was lower than ADHD group ((61.53±24.26) vs (80.89±15.19), P<0.05), while the problem behavior score of ASD group was higher than ADHD group ((38.82±11.92) vs (34.00±12.45), P<0.05). In ASD group, the scores of ABC, CARS and SCQ were negatively correlated with the score of social skills ( r=-0.26--0.55, P<0.05). In ADHD group, the total score and each subscale of SNAP-Ⅳ were positively correlated with the score of problem behavior ( r=0.25-0.65, P<0.05). Multivariate Logistic regression analysis showed that empathy was a negative influencing factor of ASD ( B=-0.246, OR=0.782, P<0.05), and hyperactivity/inattention was a positive influencing factor of ASD ( B=0.589, OR=1.802, P<0.01), while only hyperactivity/inattention was a positive influencing factor of ADHD( B=0.779, OR=2.180, P<0.01). Conclusion:Children and adolescents with ASD and ADHD both have defects in social skills and problem behaviors, and these defects are associated with the core characteristics of their respective diseases.

Objective:To summarize the clinical phenotypes, genotypes, and treatment outcomes of NPRL2-related epilepsy. Methods:This was a case summary.Clinical data of patients with NRPL2 variants admitted to the Department of Pediatrics, Peking University People′s Hospital between October 1, 2013 and October 31, 2023 were retrospectively analyzed.Previous reports of patients with the same disease were reviewed. Results:Six cases of NPRL2-related epilepsy were collected, and 37 cases were reported in the previous literatures.The age of onset ranged from 3 days to 18 years with the median age of 24 months.There were 15 patients with onset in infancy.Among the 41 patients diagnosed with epilepsy, 73.1% (30/41) had focal seizures, 34.1% (14/41) had frontal lobe epilepsy, and 17.1% (7/41) had epileptic spasms.Among the patients with known cranial imaging, 58.6% (17/29) had cortical malformations. NPRL2 variants involved 11 nonsense mutations, 10 splice site mutations, 7 frameshift mutations, 1 large fragment deletion, and 14 missense mutations; among them, 39 mutations were pathogenic or likely pathogenic, while the rest 4 mutations had unclear pathogenicity.Among the 27 patients with known outcomes, 11 (40.7%) had no seizures after administration of 1 or 2 types of drugs, and 16 (59.2%) had drug-resistant epilepsy.Among the 16 patients, 1 had no seizures after treatment with 3 types of anti seizure medications, and 7 had no seizures after surgery.Most patients had varying degrees of delay in intellectual and motor development. Conclusions:Patients with NPRL2 variants usually present with frequent focal seizures and epileptic spasms, and the age of onset varies greatly.About half of the patients have drug-resistant epilepsy, half of whom have cortical malformations.For those with drug-resistant epilepsy and abnormal cranial imaging, surgery may be considered.

Objective:To summarize the phenotype and genotype of leukoencephalopathy with calcifications and cysts(LCC).Methods:A case summary.Clinical, imaging, and genetic data of 2 patients with early-onset LCC admitted to the Department of Pediatrics, Peking University People′s Hospital between December 2023 and August 2024 were retrospectively summarized.A review of the literature was also conducted.Results:Case 1: a 19-month-old female infant presented with febrile seizures in infancy and mild developmental delay.Trio whole-exome sequencing (trio-WES) identified compound heterozygous pathogenic variants in the SNORD118 gene: n.92C>T (paternally inherited) and n. 72A>G (maternally inherited). Case 2: an 11-year-and-4-month-old girl had non-specific encephalopathy in the neonatal period, developmental delay with regression, and seizures since early childhood.Trio-WES revealed compound heterozygous pathogenic variants in SNORD118: n.3C>T (paternally inherited) and n. 57G>C (maternally inherited). Both cases showed typical imaging findings of leukoencephalopathy, intracranial calcifications, and cysts.Case 2 has been treated with Bevacizumab for 3 months and remains under follow-up.Combining this 2 cases with previously reported genetically confirmed cases, a total of 97 LCC patients with identified SNORD118 variants were analyzed.The median age of onset was 5 years.Seventy-one cases had childhood onset, including 31 cases with onset at ≤1 year.The inaugural symptoms were: seizures in 40 patients (41.2%), motor disorders in 25 patients (25.8%), developmental delay or cognitive impairment in 19 patients (19.6%) and headaches or increased intracranial pressure in 13 patients (13.4%). Neurological dysfunctions progress during the course.All patients had typical leukoencephalopathy, intracranial calcifications and cysts, with varied imaging progress.A total of 61 variants of SNORD118 were reported and most were compound heterozygous variants.Treatment is primarily symptomatic.Three out of the 4 patients treated with Bevacizumab showed improvement. Conclusions:LCC is a rare autosomal recessive inherited cerebral microangiopathy, characterized by progressive neurological dysfunction and radiological triad of diffuse and asymmetric leukoencephalopathy, intracranial calcifications and cysts.Patients with pathogenic SNORD118 variants should definitely be diagnosed.Symptomatic treatment is the mainstay therapy and Bevacizumab may slow down the progression.

OBJECTIVE: To investigate the effect of miR-483-5p on hepatocellular carcinoma (HCC) cells proliferation and stemness, as well as the attenuating effect of Pien Tze Huang (PZH). METHODS: Differentially expressed miRNA between HepG2 cells and hepatic cancer stem-like cells (HCSCs) were identified by a miRNA microarray assay. miR-483-5p mimics were transfected into HepG2 cells to explore the effects of miR-483-5p on cell proliferation and stemness. HepG2 cells and HCSCs were treated with PZH (0, 0.25, 0.50 and 0.75 mg/mL) to explore the effects of PZH on the proliferation and stemness, both in non-induced state and the state induced by miR-483-5p mimics. RESULTS: miR-483-5p was significantly up-regulated in HCSCs and its overexpression increased cell proliferation and stemness in HepG2 cells (P<0.05). PZH not only significantly inhibited proliferation in HepG2 cells, but also significantly suppressed the cell proliferation and self-renewal of HCSCs (P<0.05). The effects of miR-483-5p mimics on proliferation and stemness of HepG2 cells were partially abolished by PZH. CONCLUSIONS miR-483-5p promotes proliferation and enhances stemness of HepG2 cells, which were attenuated by PZH, demonstrating that miR-483-5p is a potential molecular target for the treatment of HCC and provide experimental evidence to support clinical use of PZH for patients with HCC.

Critically ill patients often experience significant skeletal muscle wasting due to prolonged bed rest, metabolic disorders, inflammatory responses and malnutrition, which affects the patient's mobility and may also lead to increased mortality. Timely and accurate assessment of muscle status is important for optimizing treatment strategies and improving patient prognosis. There are various limitations in the current methods of assessing muscle mass, and muscle ultrasound, as a noninvasive, convenient, low-cost and suitable technique for bedside monitoring, has received increasing attention for its application in muscle assessment of critically ill patients. However, there are still a number of challenges in its practical application, such as the lack of uniform standards for the measurement method, the high dependence on the operation, and the reproducibility of the data that needs to be optimized, and so on. The aim of this article is to systematize the research progress of muscle ultrasound in muscle assessment of critically ill patients, and to discuss the advantages and limitations of its clinical application, in order to provide a scientific basis for future research and clinical practice.

Osteoporosis is a prevalent skeletal condition characterized by reduced bone mass and strength, leading to increased fragility. Buqi-Tongluo (BQTL) decoction, a traditional Chinese medicine (TCM) prescription, has yet to be fully evaluated for its potential in treating bone diseases such as osteoporosis. To investigate the mechanism by which BQTL decoction inhibits osteoclast differentiation in vitro and validate these findings through in vivo experiments. We employed MTS assays to assess the potential proliferative or toxic effects of BQTL on bone marrow macrophages (BMMs) at various concentrations. TRAcP experiments were conducted to examine BQTL's impact on osteoclast differentiation. RT-PCR and Western blot analyses were utilized to evaluate the relative expression levels of osteoclast-specific genes and proteins under BQTL stimulation. Finally, in vivo experiments were performed using an osteoporosis model to further validate the in vitro findings. This study revealed that BQTL suppressed receptor activator of NF-κB ligand (RANKL)-induced osteoclastogenesis and osteoclast resorption activity in vitro in a dose-dependent manner without observable cytotoxicity. The inhibitory effects of BQTL on osteoclast formation and function were attributed to the downregulation of NFATc1 and c-fos activity, primarily through attenuation of the MAPK, NF-κB, and Calcineurin signaling pathways. BQTL's inhibitory capacity was further examined in vivo using an ovariectomized (OVX) rat model, demonstrating a strong protective effect against bone loss. BQTL may serve as an effective therapeutic TCM for the treatment of postmenopausal osteoporosis and the alleviation of bone loss induced by estrogen deficiency and related conditions.
