Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

Objective:To investigate the unqualified hepatitis C virus (HCV) detection result of blood donors from the served area of blood institutions.Methods:The data related to HCV markers detected of the first and repeat blood donors were collected from the system of practice comparison for the Chinese mainland blood institutions from 2017 to 2021. The anti-HCV reactive rate and the rates of anti-HCV negative but HCV-RNA reaction and all the relationship between rates and the annual, regional and different blood donors were statistically analyzed.Results:During 2017-2021, the number of anti-HCV reactive per 100 000 blood donors decreased from 444.3 to 250.44 in the served area of 22 blood institutions ( χ2=49.677, P<0.05). The number of HCV RNA detected positive per 100 000 anti-HCV negative increased from 0.69 to 2.05 year by year, but there was no statistical significance ( χ2=0.643, P>0.05). The anti-HCV unqualified rate was significantly different among regions ( χ2=3 260.283, P<0.05). The anti-HCV unqualified rate of the first blood donors was significantly higher than that of the repeated blood donors ( F=130.993, P < 0.05). The annual number of HCV RNA detected positive per 100 000 anti-HCV negative blood samples from donors ranged from 0 to 17.28. Conclusions:The anti-HCV unqualified rate of blood donors in the served area of 22 blood institutions decreased year by year. Compared with repeated blood donors, HCV infection should be emphasized in first-time blood donors. The implementation of HCV RNA test can detect out much more HCV infections and reduce the risk of transfusion transmitted infectious HCV.

This article reviews the clinical studies about the treatment of allergic rhinitis （AR） with traditional Chinese medicine （TCM） in recent years. AR is a common and frequently occurring disease in the department of otolaryngology. The common manifestations of AR include nasal congestion， sneezing， runny nose， and nasal itching. AR， belonging to the category of rhinitis， is a dominant disease in the TCM treatment of otorhinolaryngologic diseases and head and neck diseases. The ancient literature has laid a solid theoretical basis on the etiology and pathogenesis of AR. According to the ancient literature， the theoretical basis， and their own experience， modern doctors classified the causes of AR into the disorders in Zang-fu organs and six meridians. Most of the explanations focus on the disorders in Zang-fu organs， especially the lung， spleen， and kidney. The clinical studies in this field mainly involve TCM treatment alone， integrated TCM and Western medicine treatment， and TCM external treatment. These therapies have good efficacy in the clinical treatment of AR. Among them， TCM treatment alone has significant advantages in alleviating the symptoms and nasal signs， declining the scores of related scales， and reducing the eosinophil count （EOS） of nasal secretions， with definite long-term efficacy. Integrated TCM and Western medicine treatment can complement with each other. The TCM external treatment methods include acupuncture， moxibustion， acupoint catgut embedding， acupoint application， and nasal irrigation with TCM， which are safe， simple， acceptable by patients and have good therapeutic effect. Finally， the clinical research status of TCM treatment of AR was summarized， and suggestions were put forward from three aspects： standardizing the clinical research protocol of TCM， encouraging pure TCM research， and exploring the mechanism of TCM treatment on the basis of frontier research achievements. This review aims to provide higher-level evidence for subsequent clinical research and promote the research on dominant AR diseases.

Objective: To explore relationship among bullying victimization, psychological traits and suicide ideation of middle school students, and to provide suggestions for school bullying and suicide prevention for adolescents. Methods: A total of 3 635 students of 7-9th grade from 5 junior middle schools were enrolled and investigated with the Olweus Bully/Victim Questionnaire (OBVQ), psychological traits questionnaire for middle school students and suicide ideation questionnaire. Results: Prevalence of bullying victimization was 28.34% of middle school students, while the prevalence of verbal, relational and physical bullying were 22.59%, 12.05% and 7.54%, respectively. Boys had significantly higher rates of bullying victimization than girls (χ2=88.92，94.29，7.69，P<0.01). Bullying victimization was positively associated with suicidal ideation (r=0.21, P<0.01), while associated with psychological traits (r=-0.17, -0.22, P<0.01). Psychological traits had a moderating effect on the relationship between bullying victimization and suicidal ideation (β=-0.04, P<0.05). Conclusion Psychological traits can buffer the adverse effects of bullying victimization on suicidal ideation, and the critical role of psychological traits in the maintenance and development of adolescent mental health should be emphasized.

Objective:To investigate the clinical effects of retrograde anterolateral thigh perforator flaps assisted with computed tomography angiography (CTA) in repairing skin and soft tissue defects around the knee or in proximal lower leg.Methods:A retrospective cohort study was conducted. From May 2015 to October 2019, 17 patients with skin and soft tissue defects around the knee or in proximal lower leg were admitted to the Department of Orthopedics of Jizhong Energy Xingtai Mig General Hospital, including 12 males and 5 females, aged 16-65 years, with an average age of 35 years. The areas of skin and soft tissue defects after debridement ranged from 6.0 cm×3.0 cm to 15.0 cm×9.0 cm. The retrograde anterolateral thigh perforator flaps were designed according to the origin and distribution of the perforating branches in flaps and the length of the vascular pedicle examined with CTA and the condition of the wound to repair the wounds. The areas of resected flaps ranged from 6.5 cm×3.5 cm to 15.5 cm×9.5 cm. The wounds in donor sites of flaps were sutured directly or covered with medium-thickness skin grafts from healthy upper leg. The sources of the perforating branches in flaps were recorded. The lateral circumflex femoral artery, its branches, and the relative length of the vascular pedicle were compared between preoperative CTA detection and intraoperative observation. The survivals of the flaps were observed. At the last follow-up, the effects of flaps in repairing wounds were evaluated according to evaluation standard of efficacy satisfaction; the motion ranges of flexion and extension of the knee joint were measured, and the knee joint function was evaluated according to the Hohl knee joint function evaluation standard; the sensory function in the flap area was evaluated according to the sensory function evaluation standard formulated by the British Medical Research Council; the wound healing and the occurrence of complication affecting motor function of limb of flap donor sites was observed. Data were statistically analyzed with paired sample t test. Results:The perforating branches in flaps originated from descending branches, oblique branches, and rectus femoris branches of lateral circumflex femoral artery in 7, 6, and 4 patients, respectively. The flaps with blood supply from descending branches, oblique branches, and rectus femoris branches of lateral circumflex femoral artery were type 1, 2, and 3 retrograde anterolateral thigh perforator flaps, respectively. The preoperative CTA examination of lateral circumflex femoral artery and its branches were consistent with those observed during operation. The relative lengths of vascular pedicles of type 1, 2, and 3 retrograde anterolateral thigh perforator flaps calculated after CTA examination were 0.32±0.13, 0.56±0.07, and 0.56±0.15, which were close to 0.35±0.12, 0.52±0.10, and 0.53±0.12 measured and calculated during operation, respectively ( t=0.45, 0.80, 0.31, P>0.05). All flaps survived in 17 cases without vascular crisis. At the last follow-up, 16 patients were satisfied with effects of flaps in wound repair, with 1 patient feeling average about the effect; the flexion range of knee joint was 100-120°, and the extension range of knee joint was -2-0°; knee joint function was evaluated as excellent in 9 cases, good in 7 cases, and poor in 1 case; the sensory function of the flap area reached S 4 level in 2 cases, S 3 level in 8 cases, and S 2 level in 7 cases; the wounds in flap donor sites healed well; there was no adverse effect in motor function of limbs. Conclusions:Retrograde anterolateral thigh perforator flap is an effective method for repairing skin and soft tissue defects around the knee or in proximal lower leg. Preoperative CTA examination can fully show the anatomical characteristics of the branches of the lateral circumflex femoral artery and the perforating vessels of each branch, which can guide preoperative flap design and operation, thus shortening operation time and improving flap survival rate, with good clinical effects.

Objective:To investigate the relationship between childhood psychological abuse and dark triad with suicide ideation, and to provide references for suicide prevention in college students.Methods:A total of 2 995 college students from 6 universities including Guangxi, Sichuan, Henan, Guizhou and Chongqing were enrolled, and were investigated with the child psychological maltreatment scale (CPMS), dirty dozen(DD), and suicide ideation questionnaire.SPSS 26.0 software was used for correlation analysis and macro program-PROCESS was used to analyze the mediating effect.Results:The prevalence of childhood psychological maltreatment among college students was 29.32%, which in male students and students with left-behind experience (33.38%, 34.60%) were higher than that in female students and students without left-behind experience (25.65%, 25.98%)(χ 2=21.53, 25.47, both P<0.01) respectively.There was positive correlation between childhood psychological maltreatment, dark triad and suicidal ideation( r=0.32-0.41, all P<0.001). Dark triad had a partial mediating effect between childhood psychological maltreatment and suicidal ideation(effect size=0.08, 95% CI=0.06-0.10). An analysis of multiple mediating effects on the three dimensions of dark triad found that Machiavellianism and psychopathy had significant mediating effects between childhood psychological maltreatment and suicidal ideation(effect size=0.05, 95% CI=0.02-0.07; effect size=0.07, 95% CI=0.04-0.10), while narcissism had no significant mediating effect(effect size=-0.01, 95% CI=-0.01-0.01). Conclusion:Childhood psychological maltreatment can not only directly affect the suicide ideation of college students, but also further affect the suicide ideation through dark triad.

Objective:To investigate the expression of coxsackievirus-adenovirus receptor (CAR) in thymic carcinoma and the relationship between CAR and the antitumor activity of oncolytic adenovirus H101.Methods:The expression of CAR in thymic carcinoma tissues and cells were detected by RT-qPCR and Western blot. H101 expression and virus titers in Bcap-37, MP59 and T1889 cells after infection were detected by RT-qPCR and 50% tissue culture infectious dose (TCID 50). The proliferation activity and apoptosis rates of T1889 cells infected with H101 at different multiplicity of infection (MOI) were detected by CCK-8 and flow cytometry. CAR expression in T1889 cells treated with different concentrations of trichostatin A (TSA), a histone deacetylase inhibitor, was detected. H101 expression and virus titers in the TSA-treated and H101-infected cells were detected. Cell activity was detected by CCK-8. The phosphorylation levels of MARK and ERK1/2 and the expression of CAR at protein level in TSA-treated or TSA+ TBHQ (ERK activator) treated cells were detected. Results:CAR expression at both mRNA and protein levels were significantly lower in thymic carcinoma tissues than in adjacent normal tissues ( P<0.01), and lower in MP59 and T1889 cells than in thymic epithelial cells (TEC) and Bcap-37 cells ( P<0.01). H101 expression in MP59 and T1889 cells and the titers of H101 in culture supernatants were significantly lower than those in Bcap-37 cells ( P<0.01). Compared with Bcap-37 cell, the activity of MP59 and T1889 cells was significantly increased and the apoptosis rates were significantly decreased 48 h after H101 infection ( P<0.01). The expression of CAR at both mRNA and protein levels in T1889 cells treated with different concentrations of TSA increased in a dose-dependent manner. When T1889 cells were treated with 0.25 μmol/L of TSA, the expression of H101 at mRNA level and H101 titers were significantly increased ( P<0.05); the phosphorylation levels of MAPK and ERK1/2 proteins were continuously decreased; the expression of CAR was continuously increased. Compared with the TSA treatment group, the expression of CAR at protein level in the TSA+ TBHQ treatment group decreased significantly ( P<0.01), and the p-ERK1/2/ERK1/2 ratio increased significantly ( P<0.01). Conclusions:TSA could up-regulate CAR expression in thymic carcinoma by inhibiting the MARK/ERK1/2 pathway, thereby enhancing the antitumor activity of H101.

Objective:To explore the clinic effects of the head of second metatarsal bone and flap for bone and skin defect at lateral malleolus in children.Methods:Between July 2009 and May 2018, 4 children with ankle bone and skin and soft tissue defects in the Jizhong Energy Xingtai Mig General Hospital were selected, including 3 boys and 1 girl aged 4-13 years old. All cases were lateral malleolus defect with adjacent skin defect, the range of skin defect was 2.0 cm×2.0 cm -4.0 cm×5.0 cm, and the range of bone defect was 1.0-3.0 cm. The area of the flap was 2.5 cm×2.5 cm-4.5 cm × 5.5 cm, and the length of the second metatarsal head was 1.0-3.0 cm. The donor site was closed directly. After the operation, X-rays was performed to evaluate whether the ankle space and lateral malleolus longitudinal development was synchronized with the uninjured limb. Ankle joint function recovery was evaluated according to the American Orthopaedic Foot and Ankle Society (AOFAS). The outcomes of donor foot range of motion, weight-bearing, and walking were observed.Results:All the composite tissue flap survived with good blood circulation, and all the donor sites healed well. All the child patients were followed up for 0.5-2.0 years. The color and elasticity of the flaps were good, without cicatricial contracture. The patients had no inversion of ankle joint, with satisfying loading and walking function. Imaging evaluation showed that the space between ankle points and the longitudinal development of lateral malleolus were roughly synchronous with the healthy side. Two cases were graded as excellent and 2 as good according to the standard of the AOFAS.The donor's foot had normal flexion and extension function, without instability.Conclusions:The head of second metatarsal bone and flap can repair the epiphysis and soft tissue defect of lateral malleolus in children at one stage, and the reconstructed lateral malleolus can develop with the growth of children. It is a satisfactory method of reconstructing the traumatic defect of lateral malleolus in children.

Objective:To explore the safety and short-term and long-term efficacy of robot-assisted radical esophageal cancer surgery.Methods:A prospective randomized controlled trial was conducted. Patients who were preoperatively diagnosed as stage 0-IIIB esophageal squamous cell carcinoma and suitable for minimally invasive surgery in our hospital from January 1, 2014 to June 30, 2018 were prospectively enrolled. Those of age ≥75 years having received preoperative neoadjuvant therapy, contradicted to anesthesia or operation due to severe complications, with history of thoracotomy or laparotomy, with concurrent malignant tumors, without complete informations or refusing to participate in this study were excluded. Participants were randomly divided into the thoracoscopy-laparoscopy group and the robot group using a random number table in ratio of 1:1. Preoperative clinicopathological data, surgical data and postoperative outcomes were recorded. The patients were followed up mainly by telephone. Follow-up endpoint was recurrence of esophageal cancer and death. Kaplan-Meier method was used to estimate survival rate. The survival difference between the two groups was analyzed using the log-rank test.Results:According to above criteria, a total of 192 esophageal cancer patients were enrolled finally, including 144 males and 48 females with mean age of (61.9±8.6) years. The robot group had 94 cases, including 72 males and 22 females with mean age of (61.3±8.2) years, and the thoracoscopy-laparoscopy group had 98 cases, including 72 males and 26 females with mean age of (62.4±9.1) years. There were no significant differences in baseline data between the two groups (all P>0.05). Operation was abandoned in one case in each group due to extensive pleural cavity metastasis and one case in each group was converted to thoracotomy. The success rate of operation was 97.9% (92/94) in the robot group and 98.0% (96/98) in the thoracoscopy-laparoscopy group (χ 2=0.002, P=0.996). The number of lymph nodes dissected in the robot group was significantly higher than that in the thoracoscopy-laparoscopy group (29.2±12.5 vs. 22.8±13.3, t=3.433, P=0.001), while there were no significant differences in operative time, intraoperative blood loss, R0 resection rate, postoperative 30-day mortality, postoperative hospital stay, ICU stay, time to withdrawal of chest drainage tube, ICU readmission, and postoperative morbidity of complications between the two groups (all P>0.05). The median follow-up time was 21 (3 to 57) months. During the follow-up, 3 cases and 4 cases were lost, and 2 cases and 3 cases died of other diseases in the robot group and in the thoracoscopy-laparoscopy group respectively. Recurrence occurred in 39 cases during follow-up, including 14 recurrences in the robotic group with 1- and 3-year recurrence-free survival rates of 92.4% and 87.6% respectively and the median recurrence time of 15 (9 to 42) months. There were 25 recurrences in the thoracoscopy-laparoscopy group with 1- and 3-year recurrence-free survival rates of 81.7% and 67.9% respectively and the median recurrence time of 9 (3 to 42) months. There was significant difference in recurrence-free survival between the two groups (χ 2=4.193, P=0.041). Conclusions:The robotic surgical system has good oncology effect and surgical safety in the radical operation of esophageal cancer, which deserves further research and promotion.
