Objective: To analyze the consumption frequency of major foods among Chinese children aged 6-17 years old, and to provide a basis for optimizing the dietary structure of children in China. Methods: Using data from the China Nutrition and Health System Survey and Application Program for Children 0-18 years old, 56 734 children aged 6-17 years old from North, Norththeast East, Central, South, Southwest and Northwest seven regions in China were selected for the study using stratified cluster random sampling from 2019 to 2021. A food frequency questionnaire was used to investigate the intake frequency of eight food groups in a month, including fresh vegetables, fresh fruits, livestock and poultry meats, aquatic products, eggs, dairy products, legumes, and cereals and potatoes. The foods were grouped according to whether they met the recommended intake criteria outlined in the Dietary Guidelines for Chinese Residents 2022. The〖KG*2〗χ2 test was used to compare the differences in the proportion of childrens intake frequency of each food group meeting the standard in different regions and age groups. Results: The proportions of Chinese children aged 6-17 years who consumed fresh vegetables and cereals and potatoes ≥3 times/d were 12.1% and 67.2%, respectively. The proportions of children who consumed fresh fruits, livestock and poultry meats, eggs and dairy products ≥1 time/d were 50.8%, 58.8%, 36.0% and 54.3%, respectively. The proportion of legumes consumed ≥4 times/week was 37.4%, and the proportion of aquatic products consumed ≥2 times/week was 39.7%. Fresh vegetables (5.5%), fresh fruits (33.1%), and dairy products (36.4%) had the lowest frequency of meeting the recommended standards in South China, and aquatic products (27.4%) and eggs (21.1%) had the lowest frequency of meeting the recommended standards in Northwest (P<0.008 3). Conclusion The overall intake frequency of fresh vegetables, fresh fruits, legumes, and dairy products are insufficient among Chinese children, with significant regional variations.

Objective:To explore the value of magnetic resonance diffusion tensor imaging (DTI) in evaluating cerebrovascular small vessel disease (CSVD) in patients with systemic lupus erythematosus (SLE).Methods:Eighty-two patients with SLE combined with CSVD treated at Yixing People's Hospital from January to December 2022 were selected. They were divided into acute phase infarction group (16 cases), chronic phase infarction group (26 cases), and chronic ischemic lesion group (40 cases) based on routine MRI examination results. All patients underwent DTI examination to obtain the average diffusion coefficient (DCavg) and anisotropy score (FA) of the affected and contralateral normal white matter areas, and the evaluation value of DTI for CSVD in SLE patients was analyzed.Results:The DCavg value on the affected side of 82 patients was significantly higher than that on the healthy side: (11.10 ± 3.48) 10 -3 mm 2/s vs. (8.18 ± 2.42) 10 -3 mm 2/s, and the FA value on the affected side was significantly lower than that on the healthy side: 0.28 ± 0.05 vs. 0.45 ± 0.08, with a statistical significant differences ( P<0.05). The DCavg values of the acute infarction group, chronic infarction group, and chronic ischemic focus group were (11.88 ± 3.50), (9.69 ± 3.24) and (8.52 ± 2.34) 10 -3 mm 2/s, respectively, with statistical significant differences ( P<0.05). The FA values of the acute infarction group, chronic infarction group, and chronic ischemic focus group were 0.28 ± 0.04, 0.33 ± 0.06 and 0.40 ± 0.07, respectively, with statistical significant differences ( P<0.05). The receiver operating characteristic curve was drawn, and the results showed that the area under the curve (AUC) of the acute phase infarction group and the chronic phase infarction group evaluated by DCavg and FA alone and in combination were 0.757, 0.756, and 0.820, respectively. The AUC of the chronic phase infarction group and the chronic ischemic focus group evaluated by DCavg and FA were 0.772, 0.776, and 0.813, respectively. The AUC value of the combined evaluation was relatively large. Conclusions:DTI has good evaluation value for CSVD in SLE patients and can accurately determine the type of CSVD.

Objective To investigate the effect of esketamine on postoperative anxiety and cognitive function in gynecological malignant tumor patients with preoperative anxiety and cognitive decline.Methods Eighty-nine patients were selected for resection of gynecological malignant tumors,aged 18-64 years,BMI 18-28 kg/m2,ASA physical status Ⅱ or Ⅲ,the hospital anxiety and depression scale(HADS)anxiety subscale score≥8 points and montreal cognitive rating scale(MoCA)＜26 points 1 day before surgery.The patients were divided into two groups using the random number table method:the esket-amine group(group S,n = 45)and the normal saline group(group C,n = 44).In group S,esketamine 0.2 mg/kg was injected intravenously during anesthesia induction,0.25 mg·kg-1·h-1 was injected by pump during anesthesia maintenance,and esketamine 100 mg was used in the postoperative analgesic pump.Group C was given the same volume of normal saline during anesthesia induction,maintenance and PCIA analgesia,and other medications were the same as those in group S.HADS and MoCA were used to evaluate patients'anxiety and cognitive function 1 day before surgery and the 1 day and 3 days after surgery.The con-centration of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),S100 calcium-binding protein(S100β),and brain-derived neurotrophic factor(BDNF)were detected 1 day before surgery and 3 days af-ter surgery.The intraoperative dosage of remifentanil,ephedrine use rate,Ramsay sedation score 10 minutes after admission to PACU,extubation time,the number of total and effective compressions of PCIA within 48 hours after surgery,postoperative remedial analgesia,and the occurrence of adverse reactions,such as hy-pertension,hypotension,nausea and vomiting,chill,dizziness,and fever within 48 hours after surgerywere recorded.Results Compared with group C,the incidence of anxiety were significantly reduced and MoCA cognitive score were increased 1 day and 3 days after surgery,the concentrations of TNF-α,IL-6,and S100β were significantly reduced,the concentration of BDNF was significantly increased,the dosage of remifentanil was significantly reduced,the sedation score of Ramsay was significantly increased,the number of total compressions and effective compressions of PCIA within 48 hours after surgery was significantly re-duced,and postoperative fever was significantly reduced in group S(P＜0.05).There were no statistically significant differences in ephedrine use rate,extubation time,postoperative remedial analgesia rate,the in-cidence of other adverse reactions,such as hypertension,hypotension,nausea and vomiting,chills and diz-ziness within 48 hours after surgery between the two groups.Conclusion Esketamine can decrease the con-centrations of inflammatory factors and reduce nerve damage,help relieve anxiety and cognitive function of patients with gynecological malignant tumors.

A comprehensive understanding of the nutritional composition and active components of human milk are important for promoting infant health. However, in the design and implementation of scientific research on human milk, the lack of standardized research and implementation methods have led to the collection, storage, and testing processes of human milk samples being largely based on reference literature and practical experience. This has resulted in variability in the representativeness of human milk samples and differences in the comparability of research results between different studies. This article summarizes the principles and guidelines for the " Specification for collection and storage of human milk samples for research", published by the Chinese Nutrition Society on December 30, 2022, and discusses the feasibility and importance of standardized management in the process of scientific research on human milk.

Objective:To investigate the genomic manifestation and pathogenesis of osteosarcoma with different relapse pattens, which were respectively initially presented with bone metastasis or pulmonary metastasis.Methods:From May 1, 2021 to October 1, 2021, 38 fresh tumor specimens and some paraffin-embedded specimens of high-grade osteosarcoma were collected in Peking University People's Hospital, including 29 males and 9 females, aged 19.6±2.2 years (range, 6-61 years). Among the 38 cases, 12 cases had initial bone metastasis (group A) and 26 cases had initial lung metastasis (group B), of which 15 cases (40%, 15/38) had paired specimens of primary and metastatic lesions. Based on Illumina NovaSeq 6000, we analyzed whole-exome sequencing (WES) as well as transcriptome for osteosarcoma with paired samples in different relapse patterns. During all their treatment courses, we also collected their paired samples to reveal these tumors' evolution. We sought to redefine disease subclassifications for osteosarcoma based on genetic alterations and correlate these genetic profiles with clinical treatment courses to elucidate potential evolving cladograms.Results:We found that osteosarcoma in group A mainly carried single-nucleotide variations (83%, 10/12), displaying higher tumor mutation burden [4.9 (2.8, 12.0) & 2.4 (1.4, 4.5), P=0.010] and neoantigen load [743.0 (316.5, 1,034.5) & 128.5 (49.0, 200.5), P=0.003], while those in group B mainly exhibit structural variants (58%, 15/26). The mutation spectrum showed that there was a significant difference in age-related gene imprinting 1 between the bone metastasis group and the lung metastasis group ( P=0.005). Samples were randomly selected from group A (3 patients) to investigate immunologic landscape by multiplex immunohistochemistry, from which we noticed tertiary lymphatic structure from one patient from group A. High conservation of reported genetic sequencing over time was found in their evolving cladograms. Conclusion:Osteosarcoma with mainly single-nucleotide variations other than structural variants might exhibit biological behavior predisposing toward bone metastases with older in age as well as better immunogenicity in tumor microenvironment.

Objective:To compare the safety and efficacy of laparoscopy and laparotomy for 5-10 cm intermediate-risk gastric stromal tumor, and to evaluate whether there was evident benefits of postoperative adjuvant treatment with imatinib.Methods:A retrospective study was conducted on 72 patients with moderate risk gastric stromal tumors (5-10 cm in diameter) who received operation in Nanjing Drum Tower Hospital from January 2010 to July 2020. There were 28 cases in the laparoscopy group and 44 cases in the laparotomy group. The clinical features, pathological data, perioperative results and hospitalization costs were compared between the two groups. The survival rates of postoperative adjuvant therapy with or without imatinib were analyzed and compared.Results:There was no significant difference in clinicopathological features between the two groups ( P>0.05). The incidences of postoperative complications in the laparoscopy group and the laparotomy group were 32.1% (9/28) and 52.3% (23/44) respectively, showing no significant difference ( P=0.094). Compared with the laparotomy group, both the hospital stay (12.5±3.2 days VS 15.0±3.5 days, P=0.004) and the median postoperative hospital stay (7.5 days VS 9.0 days, P=0.006) in the laparoscopy group were significantly shorter, and the first exhaust time was significantly shorter ( P=0.003). During the median follow-up period of 58 months (13-129 months), there was no tumor-related death. Two cases died of breast cancer and heart disease in the laparotomy group, and 1 case died irrelevant to gastric stromal tumor in the laparoscopy group. Of the 72 patients, 40 received postoperative imatinib adjuvant therapy, 22 cases (50.0%) in the laparotomy group and 18 cases (64.3%) in the laparoscopy group, with no significant difference in the proportion ( χ2=1.414, P=0.234). There was significant difference in the overall survival rate between the group treated with imatinib and the group without imatinib ( P=0.015). Conclusion:Laparoscopic resection is safe and effective for intermediate-risk gastric stromal tumor of 5-10 cm. Taking imatinib adjuvant treatment does not increase overall survival rate of patients with intermediate-risk gastric stromal tumors (5-10 cm), and there is no tumor-related death, recurrence or metastasis for those who did not accept imatinib adjuvant treatment after R0 resection.

Objective:To investigate the correlation of the expressions of programmed death ligand 1 (PD-L1) and interleukin-10 (IL-10) with the prognosis in uterine cervical cancer tissues.Methods:A total of 82 patients with uterine cervical cancer hospitalized at Nantong Maternal and Child Health Hospital from January 2015 to December 2019 were retrospectively analyzed, and the clinicopathological data of all patients were collected and sorted out. Immunohistochemical method was used to detect the positive expression of PD-L1 protein in cancer tissues, and Western blot was used to detect the expression level of IL-10 protein in cancer tissues. The survival of all patients for 24-month follow-up was recorded and 82 patients were divided into the survival group and the death group. The clinicopathological characteristics and the expressions of PD-L1 and IL-10 in both groups were compared. Multivariate Cox proportional risk model was used to analyze the factors affecting the survival of patients with uterine cervical cancer. The value of PD-L1 and IL-10 expressions predicting the survival in uterine cervical cancer was evaluated by using receiver operating characteristic (ROC) curve. The best cut-off value of IL-10 relative expression in cancer tissues obtained from ROC curve analysis predicting 24-month survival of patients was used to group; ≥ the best cut-off value was treated as IL-10 high expression group, and < the best cut-off value was treated as IL-10 low expression group. Kaplan-Meier method was used to compare the survival of PD-L1 positive and negative groups, IL-10 high and low expression groups.Results:There was no loss of follow-up in 82 patients during 24-month follow-up, of which 11 cases (13.4%) died and 71 cases (86.6%) survived. The proportion of patients with Federation International of Gynecology and Obstetrics (FIGO) staging Ⅲ-Ⅳ, poor differentiation, tumor long diameter > 4 cm and lymph node metastasis in the death group was higher than that of those in the survival group (all P < 0.05). PD-L1 was positive in 9 of 11 patients in the death group and 11 of 71 patients in the survival group ( P < 0.001). The relative expression level of IL-10 protein in the death group was higher than that in the survival group (1.18±0.32 vs. 0.89±0.21, P < 0.001). Multivariate Cox regression analysis showed that FIGO staging, tissue differentiation degree, tumor long diameter, whether lymph node had metastasis or not, whether PD-L1 was positive and the relative expression level of IL-10 protein were independent factors affecting patients' 24-month survival (all P < 0.05). ROC curve analysis showed that the area under the curve (AUC) of PD-L1 and IL-10 single and the combination of both predicting 24-month survival in cancer tissues was 0.748 (95% CI 0.664-0.894), 0.710 (95% CI 0.655-0.884) and 0.839 (95% CI 0.742-0.951), respectively. There were 20 cases in PD-L1-positive group and 62 cases in PD-L1-negative group. The best cut-off value of relative expression level of IL-10 protein was 7.12. There were 19 cases in IL-10 high expression group and 63 cases in IL-10 low expression group. The overall survival of patients in PD-L1-positive group was worse than that in PD-L1-negative group (24-month overall survival rate: 55.0% vs. 96.8%, P = 0.001). The overall survival of patients in IL-10 high expression group was worse than that in IL-10 low expression group (24-month overall survival rate: 57.9% vs. 95.2%, P = 0.001). Conclusions:The prognosis of patients with positive PD-L1 and IL-10 high expressions in uterine cervical cancer tissues is poor. The combined detection of PD-L1 and IL-10 has a high predictive effect on the prognosis.

ObjectiveTo estimate the total effect size and the proportion of contextual effect (PCE) of non-surgical treatments for rotator cuff injury. MethodsRandomized controlled trial (RCT) on non-surgical treatments for rotator cuff injuries was retrieved from PubMed, Embase, Cochrane Library, Web of Science, CINAHL, CNKI, and Wanfang Data from the establishment to October, 2020. Two researchers conducted independent literature screening, data extraction and quality evaluation, and used STATA 15.0 software for meta-analyses. ResultsForty studies involving 2 976 participants were included. The total PCE of pain was 0.61 (95% CI 0.54 to 0.69). PCE of treatments from the largest to the smallest were corticosteroid injection, extracorporeal shockwave therapy, oral non-steroidal anti-inflammatory drugs (NSAIDs), manual therapy, hyaluronic acid injection therapy, platelet-rich plasma injection therapy, laser therapy, NSAIDs injection therapy, and acupuncture therapy. Total PCE for function and range of motion was 0.69 (95% CI 0.61 to 0.77) and 0.62 (95% CI 0.48 to 0.81), respectively. Blinding, studies in developed countries, and longer courses of treatment increased the PCE of pain. ConclusionUp to 61% of PCE for the non-surgical treatments for rotator cuff injuries means instable research. A higher proportion of PCE may be the cause of inconsistencies between clinical practice and clinical research conclusions.

OBJECTIVE: To summarize the clinical phenotype and genotypic characteristics of 3 patients with KBG syndrome and epileptic seizure. METHODS: Clinical data of the patients were collected. Family-trio whole exon sequencing (WES) was carried out. Candidate variants were verified by Sanger sequencing. RESULTS: Patients 1 and 2 were boys, and patient 3 was an adult woman. All patients had epileptic seizures and mental deficiency. Their facial features included triangular face, low hair line, hypertelorism, large forward leaning auricles, broad nasal bridge, upturned nostrils, long philtrum, arched upper lip, and macrodontia. The two boys also had bilateral Simian creases. WES revealed that the three patients all harbored heterozygous de novo frameshift variants in exon 9 of the ANKRD11 gene including c.2948delG (p.Ser983Metfs*335), c.5397_c.5398insC (p.Glu1800Argfs*150) and c.1180_c.1184delAATAA (p.Asn394Hisfs*42). So far 291 patients with ANKRD11 gene variants or 16q24.3 microdeletions were reported, with over 75% being de novo mutations. CONCLUSION Above findings have enriched the spectrum of ANKRD11 gene mutations underlying KBG syndrome. WES is helpful for the early diagnosis of KBG, and provided reference for genetic counseling of this disease.
