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）.

Objective:To compare the prognostic impact of complete mesocolic excision (CME) versus D2 lymphadenectomy in patients with stage III right-sided colon cancer.Methods:A retrospective cohort study was conducted. Clinical data of 263 patients with stage III colon cancer undergoing right hemicolectomy in the Division of Colorectal Surgery, Department of General Surgery, Peking Union Medical College Hospital (January 1, 2016 to August 8, 2023) were included. Of the 263 patients, 152 underwent CME and 111 received D2 dissection. Propensity score matching (PSM) was employed to balance baseline characteristics between the two groups. Continuous variables were compared using the Mann-Whitney U test or Student's t-test; categorical variables were compared using the χ2 test or Fisher exact test. Survival curves were constructed using the Kaplan-Meier method, and the Log-Rank test was used to compare disease-free survival (DFS) and overall survival (OS) between groups. Cox proportional hazards models were utilized to analyze prognostic factors, with subgroup analyses performed.Results:Patients undergoing CME surgery were younger (proportion >75 years: 4.6% vs. 25.2%, P<0.001), had a lower burden of comorbidities (Charlson comorbidity index ≥ 1: 25.0% vs. 36.9%, P=0.045), The rates of open surgery and converted open surgery were lower [0.6% (1/152) vs. 4.5% (5/111) and 0.6% (1/152) vs. 2.7% (3/111), respectively; P=0.040].They also had a higher rate of receiving adjuvant therapy (92.7% vs. 76.0%, P<0.001). In terms of short-term postoperative outcomes, the CME group had a greater number of harvested lymph nodes (median: 30 vs. 25, P<0.001) and less blood loss (median: 20 ml vs. 20 ml, P=0.041). There were no significant differences between the groups in terms of the number of metastatic lymph nodes, operation time, and the incidence of postoperative complications. Survival analysis demonstrated significantly longer DFS in the CME group both before and after PSM. CME was an independent favorable prognostic factor for DFS (pre-PSM: HR=0.53, 95%CI: 0.31-0.91, P=0.022; post-PSM: HR=0.50, 95%CI: 0.26-0.97, P=0.042). No significant difference in OS was detected between the two groups across models. The subgroup analysis based on clinicopathological features revealed DFS benefits associated with CME in patients with tumor deposits (HR=0.41, 95%CI: 0.18-0.94, P=0.035), moderately-to-well-differentiated adenocarcinoma(HR=0.48, 95%CI: 0.26-0.90, P=0.023), proficient mismatch repair tumors (HR=0.55, 95%CI: 0.32-0.94, P=0.030), and pN2 stage disease (HR=0.43, 95%CI: 0.19-0.95, P=0.036). Conclusion:An extended lymph node dissection, as exemplified by CME, may confer a DFS advantage in patients with stage III right-sided colon cancer, especially those exhibiting a substantial burden of lymph node metastases.

Objective:To explore the relationship between childhood trauma and anxiety symptom among high school students,as well as the mediating role of social support and the moderating role of stressful life events.Methods:A total of 3 075 high school students were selected.The Short Form of the Childhood Trauma Questionnaire(CTQ-SF),Social Support Rate Scale(SSRS),Adolescent Self-Rating Life Events Checklist(ASLEC)and Chinese Secondary School Students Anxiety Scale(CSSAS)were used to assess the levels of child-hood trauma,social support,stressful life events,and anxiety symptom severity.The SPSS PROCESS 3.3 macropro-gram was used to test the mediating effect and moderated mediation effect.Results:The CTQ-SF scores were posi-tively correlated with CSSAS scores(r=0.26,P＜0.001).The SSRS scores and the subjective support(S2)scores and availability of support(S3)scores in the SSRS played partial mediating effects between CTQ-SF scores and CSSAS scores.The mediating effects were 0.11(95％CI:0.09-0.12,P＜0.001),0.08(95％CI:0.06-0.09,P＜0.001),0.04(95％CI:0.03-0.06,P＜0.001)respectively,which accounted for 44.00％,32.00％,16.00％of the total effect respectively.The ASLEC scores moderated the relationship between CTQ-SF scores and CSSAS scores(β=0.02,P=0.044),and the relationship between SSRS scores and CSSAS scores(β=0.08,P＜0.001).Conclusion:Among high school students,social support and the subjective support and availability of support in so-cial support play partial mediating effects between childhood trauma and anxiety symptom,and stressful life events moderates the relationship between childhood trauma,social support and anxiety symptom.

Porphyrin and its derivatives exhibit diverse biochemical properties because of their unique molecular structures,and have been widely used and recognized in the field of tumor therapy.The applications of chemical modifications and nanotechnology have not only significantly enhanced the biological activity of porphyrins and their derivatives but also substantially improved the drug delivery efficiency.In addition,the applications of porphyrins and their derivatives in multiple therapeutic methods,including photodynamic therapy(PDT),sonodynamic therapy(SDT),radiotherapy and immunotherapy,have opened the door for the implementation of tumor multimodal treatment strategies.This cross-disciplinary integration facilitates the overcoming of limitations inherent to single-modality treatments,thereby synergistically enhancing overall therapeutic efficacy aganist tumors.This review systematically summarizes recent advances in the applications of porphyrins and their derivatives within the aforementioned therapeutic treatments,and the challenges and future development potential of porphyrins and their derivatives in tumor therapy are respectively discussed and prospected.

ObjectiveCongenital heart disease （CHD） is a common birth defect in children， with its incidence increasing annually. Because of their special health status， the vaccination situation for children with CHD has become a focal point of attention. This paper systematically reviews the current status of vaccination among children with CHD in China to identify existing issues in vaccination efforts for children with CHD， provide guidance for increasing vaccination rates among children with CHD， reduce the incidence of vaccine-preventable diseases， and provide ideas for subsequent research. MethodsLiterature on the vaccination of children with CHD in China was searched in both Chinese and English databases， including CNKI， Wanfang Data Knowledge Service Platform， VIP， Chinese Biomedical and Web of Science， PubMed， EmBase， and the Cochrane Library. Relevant literature was identified based on inclusion and exclusion criteria， and data extraction was carried out to summarize the research results. ResultsA total of 15 studies were included. Three articles focusing on expert consensus （guideline recommendations） for vaccination of children with CHD in China all agreed that vaccination is both feasible and necessary for children with CHD. Systematic analysis found that the overall timely vaccination rate for children with CHD was between 34% and 50%， with a notable delay in vaccination. However， after professional outpatient assessment， the vast majority of children with CHD were advised to be vaccinated according to the national recommended schedule， with only about 2% of them being advised to delay vaccination. The proportion of children with CHD who reported suspected adverse events following immunization （AEFI） was low and not significantly different from that of healthy/control children. ConclusionThe safety of vaccinations for children with CHD in China is relatively high， but the total timely vaccination rate is currently low. In order to improve the coverage and timeliness of vaccination in children with CHD， it is recommended that relevant departments provide vaccination policy support. There is a lack of research on the effectiveness of vaccination in children with CHD， so further studies are urgently needed to further improve the vaccination strategy for children with CHD in China.

Objective:To explore the impact on safety and prognosis in patients with right-sided colon cancer participating in surgical clinical research.Methods:This retrospective cohort study utilized data from a randomized controlled trial (RELARC study) conducted by the colorectal surgery group at Peking Union Medical College Hospital in which laparoscopic complete mesocolic excision (CME) was compared with D2 radical resection for the management of right-sided colon cancer. The eligibility criteria were age 18–75 years, biopsy-proven colon adenocarcinoma, tumor located between the cecum and right 1/3 of the transverse colon, enhanced chest, abdomen, and pelvic CT scans suggesting tumor stage T2–T4N0M0 or TanyN+ M0, and having undergone radical surgical treatment from January 2016 to December 2019. Exclusion factors included multiple primary colorectal cancers, preoperative stage T1N0 or enlarged central lymph nodes, tumor involving surrounding organs requiring their resection, definite distant metastasis or otherwise unable to undergo R0 resection, history of any other malignant tumors within previous 5 years, intestinal obstruction, perforation, or gastrointestinal bleeding requiring emergency surgery, and assessed as unsuitable for laparoscopic surgery. Patients who had participated in the RELARC study were included in the RELARC group, whereas those who met the inclusion criteria but refused to participate in the RELAEC study were included in the control group. The main indicators studied were the patient's baseline data, surgery and perioperative conditions, pathological characteristics, adjuvant treatment, and postoperative follow-up (including average frequency of follow-up within the first 3 years) and survival (including 3-year disease-free survival rate (DFS) and 3-year overall survival rate (OS). Differences in these indicators between the RELARC and control groups were compared.Results:The study cohort comprised 290 patients, 173 in the RELARC group (RELARC-CME group, 82; RELARC-D2 group, 91) and 117 in the control group (CME control group, 72; D2 control group, 45). There was a significantly higher proportion of overweight patients (BMI ≥24 kg/m 2) in the RELARC-CME than in the CME control group (67.1% [55/82] vs. 33.3% [24/72], χ 2=17.469, P<0.001). There were no other statistically significant differences in baseline characteristics (all P>0.05). No significant disparities were found between the CME and D2 groups in terms of operation duration, intraoperative blood loss, rate of conversion to open surgery, combined organ resection, intraoperative blood transfusion, or intraoperative complications (all P>0.05). There was a trend toward Clavien–Dindo grade II or higher postoperative complications in the RELARC-CME group (24.4% [20/82]) than in the CME control group (18.1% [13/72]); however, this difference was not statistically significant (χ 2=0.914, P=0.339). Similarly, the difference in this rate did not differ significantly between the RELARC-D2 group (25.3% [23/91]) and D2 control group (24.4% [11/45], χ 2=0.011, P=0.916). The median duration of postoperative follow-up was significantly shorter in the RELARC groups than in the corresponding control groups. Specifically, the median duration of follow-up was 4.5 (4.5, 4.5) months in the RELARC-CME and 7.2 (6.0, 9.0) months in the CME control group ( Z=-10.608, P<0.001). Similarly, the median duration of follow-up was 4.5 (4.5, 4.5) months in the RELARC-D2 group as opposed to 8.3 (6.6, 9.0) months in the D2 control group ( Z=-10.595, P<0.001). The 3-year DFS rate (91.5%) and OS rate (96.3%) tended to be higher in the RELARC-CME group than in the CME control group (84.7% and 90.3%, respectively). The 3-year DFS rate (87.9%) and OS rate (96.7%) tended to be higher in the RELARC-D2 group than in the D2 control group (81.8% and 88.6%, respectively); however, these differences were not statistically significant (all P>0.05). Subgroup analysis according to pathological stage revealed that patients in the RELARC-D2 group with pN0 stage achieved a significantly superior 3-year OS rate than did those in the D2 control group (100% vs. 88.9%, P=0.008). We identified no statistically significant differences in survival rates between the remaining subgroups (all P>0.05). Conclusions:A high-quality surgical clinical trial with close follow-up can achieve perioperative safety and a trend toward improved survival outcomes.

Objective:To study the clinical and genetic features of neonatal Schaaf-Yang Syndrome (SYS).Methods:The clinical data of a newborn with SYS admitted to our hospital in October 2022 were retrospectively analyzed. Using "Schaaf-Yang syndrome", "newborn", "preterm", "neonate" as keywords, we searched the CNKI, Wanfang Database, VIP database, Chinese Medical Journal Full Text Database, PubMed, Embase, Web of Science and the Cochrane Library for literature published during the date of establishment to March 24th, 2023. The clinical and genetic features of neonatal SYS from published literature were summarized.Results:The patient in this case was a female preterm infant with a gestational age of 33 +3 weeks, characterized by epiglottic collapse, hypotonia, poor response, weak sucking and swallowing, respiratory failure, and abnormalities such as bilateral low ear position and short limbs. The patient received symptomatic treatment, often failed to withdraw the ventilator, and had difficulty intubating. Meanwhile, whole exome sequencing identified a de novo truncated variant c.2892del (p.Trp965Glyfs*3) in the MAGEL2 gene of the patient. At 30 d after birth, the patient died after giving up treatment by her family. A total of 11 retrieved literatures had neonatal records, including 17 cases. The clinical features involved joint contracture (15/17), hypotonia (14/17), respiratory failure (12/17), and feeding difficulties (12/17). Most of the gene variation was truncated mutation, and only 1 heterozygote deletion mutation was found. These gene variation included c.1996dupC(p.Gln-666Profs*47) variation in 7 cases, c.1912C>T(p.Q638X) variation in 3 cases, c.1996C>T(p.Q666*) in 1 case, c.2847-2883del37 in 1 case, c.2118delT(p.Leu708Trpfs*7) in 1 case, c.1850G>A(p.RP617*) in 1 case, c.2167delG (p.Ala723Profs*4) in 1 case, c.2005C>T(p.Gln669) in 1 case, c.2892del(p.Trp965Glyfs*3) in 1 case, respectively. Conclusions:The main manifestations of neonatal SYS included hypotonia, feeding difficulties, respiratory failure and joint contracture. Most of the mutations were truncated mutations of c.1996dupC (p.Gln-666Profs*47).
