To summarize Professor GAO Shuzhong's clinical experience in treating idiopathic tinnitus with a combination of acupuncture and Chinese meteria medica. It is believed that idiopathic tinnitus is mostly caused by weak lungs and spleen， kidney essence deficiency， liver constraint transforming into fire， and binding constraint of heart qi. Treatment advocates the combination of acupuncture and Chinese meteria medica in clinical practice. Acupuncture treatment mainly focus on the method of opening the orifices by syndrome identification in combination with Ermen （TE 21）， Tinggong （SI 19）， Tinghui （GB 2）， Shenmai （BL 62） to regulate qi and blood， and supporting with Baihui （GV 20）， Yintang （EX-HN 3）， Taichong （LR 3）， and Yanglingquan （GB 34） to soothe the liver， resolve constraint， and calm the mind. Oral administration of Chinese medicinal prescription usually includes modified Yiqi Congming Decoction （益气聪明汤） and Tongqi Powder （通气散）， and the external administration of Chinese medicinal prescription can apply self-prescribed Wenqing Powder （温清散） to navel moxibustion.

Objective: To investigate the association between dietary quality and overweight / obesity among primary school students, so as to provide a basis for the prevention and control of childhood obesity. Methods: In September 2022, third-grade students from six primary schools in Ningbo City, Zhejiang Province were selected by a random cluster sampling method. Data on gender, age, height, and weight were collected through questionnaire surveys and physical examinations. Body mass index (BMI) was calculated, and overweight and obesity were determined using gender- and age-specific BMI cut-off points. The Chinese dietary quality questionnaires was administered to assess the intake of health-promoting and restricted foods over the past 24 hours, thereby evaluating overall dietary quality. A multivariate logistic regression model was used to analyze the association between dietary quality and overweight / obesity among primary school students. Results: A total of 1 375 primary school students were included, comprising 722 (52.51%) boys and 653 (47.49%) girls, with a mean age of (8.47±0.30) years. Among them, 165 (12.00%) were overweight and 171 (12.44%) were obese. The score for health-promoting foods was (4.29±2.27) points. The median score of restricted foods was 2.00 (interquartile range, 3.00) points. The total dietary quality score was (10.84±2.42) points. Multivariable logistic regression analysis indicated that the restricted food score was positively associated with overweight (OR=1.073, 95%CI: 1.002-1.148), while the total dietary quality score was negatively associated with overweight (OR=0.911, 95%CI: 0.851-0.976). However, no statistically significant associations were observed between the health-promoting food score and overweight or obesity (both P>0.05), nor between the restricted food score or total dietary quality score and obesity (both P>0.05). Conclusion A higher intake of restricted foods was associated with an increased risk of overweight, while a better dietary quality was associated with a decreased risk of overweight among primary school students.

OBJECTIVE: To investigate short-term effectiveness of robot-assisted fracture reduction and fixation combined with arthroscopic exploration for posterolateral depressed tibial plateau fractures. METHODS: Between January 2022 and January 2024, 8 patients with posterolateral depressed tibial plateau fractures (Schatzker type Ⅲ) were treated using robot-assisted fracture reduction and fixation combined with arthroscopic exploration, with simultaneous treatment of concomitant ligament or meniscus tears. There were 3 males and 5 females with an average age of 54.1 years (range, 42-68 years). Injury mechanisms included traffic accidents (3 cases) and falls (5 cases). The time from injury to operation ranged from 2 to 4 days (mean, 3.1 days). Operation time, intraoperative blood loss, hospital stay duration, visual analogue scale (VAS) score for pain, and complications were recorded. Fracture healing and knee Rasmussen scores were assessed radiographically, while knee function was evaluated using range of motion and Hospital for Special Surgery (HSS) scores. RESULTS: All operations were successfully completed. The operation time was 108-129 minutes (mean, 120.1 minutes). The intraoperative blood loss was 10-100 mL (mean, 41.3 mL). The hospital stay duration was 4-7 days (mean, 5.6 days). All incisions healed by first intention without complication such as peroneal nerve injury, vascular damage, or infection. All patients were followed up 32-48 weeks (mean, 40 weeks). Radiographic follow-up confirmed that the knee Rasmussen scores rated as excellent in 8 patients and all fractures healed with the healing time of 12-16 weeks (mean, 13.5 weeks). The VAS score for pain was 2-4 (mean, 2.8) at discharge and improved to 0 at 1 month after operation. The knee range of motion was 80°-110° (mean, 96.1°) at discharge and increased to 135°-140° (mean, 137.9°) at 1 month after operation. At 3 months after operation, the HSS score was 91-94 (mean, 92.8), all graded as excellent. No severe complication, including implant failure, occurred during follow-up. CONCLUSION For posterolateral depressed tibial plateau fractures, the minimally invasive approach combining robot-assisted fracture reduction and fixation with arthroscopic exploration demonstrates multiple advantages, including shorter operation time, reduced intraoperative blood loss, excellent wound healing, fewer complications, and rapid recovery of knee function. This technique achieves satisfactory short-term effectiveness, while its long-term effectiveness requires further evaluation.

Objective To investigate the function of the glutamic-oxaloacetic transaminase 2(GOT2)gene in acute myeloid leukemia cells.Methods ShRNAs targeting at GOT2 were constructed to suppress GOT2 expression in the THP-1 human monocytic leukemia cell line.GOT2 mRNA level was measured by RT-qPCR,and GOT2 protein ex-pression was measured by Western blot.Intracellular free amino acid level was quantified using colorimetric assays.The impact of GOT2 knockdown in THP-1 cell function was evaluated through cell viability(CCK-8 assay)and ap-optosis(flow cytometry).Results After GOT2 knockdown,both GOT2 mRNA and protein were significantly de-creased in THP-1 cells(P＜0.05).Compared to the control group,GOT2 knockdown did not affect intracellular glutamate levels(P＞0.05),but led to a marked decrease in aspartate level(P＜0.05).GOT2 knockdown signifi-cantly impaired THP-1 cell viability,inhibited cell proliferation(P＜0.05)and promoted apoptosis(P＜0.05).Conclusions Down regulation of GOT2 significantly decreases intracellular aspartate level in acute myeloid leukemia cells,impairs cellular viability and induces apoptosis,which suggests that GOT2 may play a key role in the regula-tion of amino acid metabolism in acute myeloid leukemia.

Objective To investigate the effect of PIAS3 on glucose fluctuation-induced oxidative stress and mito-chondrial dysfunction in rat cardiomyocytes.Methods H9c2 were cultured in vitro,and divided into normal glucose control group(Control),mannitol-induced osmotic pressure control group(MG),constant high glucose group(HG),intermittent hyperglycemia group(IHG),IHG+siRNA NC group,and IHG+PIAS3 siRNA group.Cell proliferation was assessed using CCK-8 assay.LDH release,MDA and GSH levels,as well as SOD activity,were detected using corresponding kits.Mitochondrial membrane potential was evaluated via JC-1 staining combined with flow cytometry.ROS levels in cells and mitochondria were determined using DCFH-DA and MitoSOX staining,re-spectively.Protein expression of PI3K,p-PI3K,AKT,and p-AKT was analyzed by Western blot.Results Com-pared with the control group,intermittent hyperglycemia promoted oxidative stress and mitochondrial dysfunction,significantly upregulated PIAS3 expression(P＜0.001)and downregulated p-PI3K and p-AKT protein levels(P＜0.001).Knockdown of PIAS3 significantly alleviated oxidative stress and mitochondrial dysfunction induced by glucose fluctuations,and increased p-PI3K and p-AKT protein levels(P＜0.001).Conclusions Knockdown of PIAS3 may alleviate glucose fluctuation-induced oxidative stress and mitochondrial dysfunction in ratcardiomyocytes by activating the PI3K/AKT signaling pathway.

Objective: To understand the current situation of school based sexuality education, attitudes and evaluations of teachers and students toward sexuality education, so as to provide evidence for promoting the development of school based sexuality education. Methods: From September to October 2021, 2 140 valid data from students in basic education and 2 146 from kindergarten and primary and secondary school teachers were collected by online questionnaire. The data were described and statistically analyzed, and the influencing factors of teachers willingness to teach sexuality education courses were explored by logistic regression analysis. Results: About 52.06% of the students had not received sexuality education in school, and 47.53% of the teachers did not carry out sexuality education in the school. Sexuality education in schools mainly focuses on reproductive health and physical development. About 48.93% of the teachers thought that the implementation of sexuality education in schools was not good, and the proportion of high school students who thought sexuality education in schools were "very bad" (32.87%) or "not very good" ( 21.23 %) was the highest. The teachers who undertook sexuality education were mainly mental health teachers (55.51% reported by teachers, 43.96% reported by students). About 71.02% of teachers believe that the best way to carry out sexuality education classes was to set up sexuality education curriculum. Students and teachers reported the need for sexuality education, and more than 50% of primary school students and high school students thought that sexuality education were "very needed" and "somewhat needed". About 51.77 % of teachers considered sexuality education "very urgent". All increased recognition of sexuality education, confidence in answering sex questions, external support for sexuality education, and acceptance of sexuality education training increased the likelihood of teachers teaching sexuality education ( OR =1.02, 1.95, 1.03, 3.53, P <0.05). Conclusion The current situation of school based sexuality education is not optimistic, the gap between sexuality education and students needs is wide, and the abilities of sexuality education teachers are insufficient.

Objective:To investigate the dynamic trend of platelet（PLT）count and mean platelet volume（MPV）in children with severe community-acquired pneumonia（SCAP）in PICU and their correlation with prognosis.Methods:A retrospective study was conducted in 215 SCAP children who were admitted to the PICU of Beijing Children's Hospital Affiliated to Capital Medical University from January 2016 to December 2019.According to the disease outcome，the patients were divided into improvement group ( n=184) and unrecovered group ( n=31).The changes of PLT count and MPV at admission，on the 2nd，3rd，and 7th days of hospitalization and before discharge were observed，and the relationship between changes in PLT parameters and poor prognosis was analyzed. Meanwhile，the correlation between thrombocytopenia on admission and on the 7th day of hospitalization and prognosis was further explored. Results:The PLT count of improvement group at admission，on the 2nd，3rd，and 7th days of hospitalization and at discharge[(328±159, 329±137, 362±159, 439±168, 510±171)×10 9/L] were significantly higher than those of unrecovered group [(210±142, 207±152, 267±143, 260±162, 343±159)×10 9/L]（ P＜0.05）.Although the MPV of improvement group [(10.9±1.9)fL] on admission was significantly lower than that of the unrecovered group[(12.7±2.5) fL]（ P＜0.05），there was no significant difference in MPV between two groups on the 2nd，3rd，7th days of hospitalization and discharge（ P＞0.05）.In addition，compared with the admission，children in improvement group had significantly higher PLT count on the 7th day of hospitalization and before discharge（ P＜0.05），but there was no significant change in unrecovered group（ P＞0.05）.Compared with SCAP patients with thrombocytopenia at admission (PLT＜100×10 9/L)( n=22),those with thrombocytopenia on 7th day of hospitalization had a significant higher rate of non recovery( P＜0.05). Conclusion:The occurrence of thrombocytopenia on admission and after 7 days of hospitalization in children with SCAP is associated with poor prognosis.No significant increase or decrease in PLT count after 7 days of hospitalization is often indicative of poor prognosis.Dynamic monitoring of PLT parameter changes may help to better judge the prognosis of severe pneumonia.

Botulinum toxin A (BTX-A) is a powerful neurotoxin produced by Clostridium botulinum, which can relieve muscle spasm or limit gland secretion by inhibiting the release of acetylcholine at the neuromuscular/glandular junction. In addition, BTX-A can also play a role in the sensory feedback loop, which can ease pain. Currently, dentists are paying more attention to the cosmetic applications of BTX-A in the oral and maxillofacial region, while their understanding of BTX-A′s non-cosmetic applications is still insufficient. Although the specific molecular mechanism of BTX-A in oral diseases has not been fully clarified, with the development of evidence-based medicine, more and more clinical evidence has began to support the effectiveness of BTX-A in the therapeutic applications of oral diseases. This article will briefly review the main molecular mechanisms of BTX-A, the latest clinical research progress of BTX-A at home and abroad in the treatment of oral diseases, clinical contraindications and adverse reactions of BTX-A, providing a new idea for the treatment of oral diseases.

Objective: To explore perceived social support levels of vocational school students and associated factors, so as to provide a basis for the fine tuned construction of social support networks for vocational school students. Methods: Adopting a combination of multi stage cluster sampling and convenience sampling method, a sample of 11 767 vocational school students in Shanghai City and Jiangsu Province were selected to conduct two surveys (November 2021 and November 2022) by using a self administered electronic questionnaire regarding personal, family, school information and the Child and Adolescent Social Support Scale (CASSS). Correlates were analyzed by generalized linear estimating equations (GEE). Results: The total perceived social support scores in percentage at baseline and follow up survey were (66.13±20.46) and (67.65±21.18). The results of GEE showed that in terms of personal characteristics, girls had higher emotional support and evaluative support scores than boys ( B=0.60, 0.68, P < 0.05 ); extraversion, non-smoking, non-drinking, exercising ≥1 time per week, and better quality of sleep were positively correlated with the total score and the different types scores of precieved social support, and time spent on the Internet >2 h/d was negatively correlated with the total score and the different types scores of precieved social support ( B=1.03-4.49, -4.04--0.58, P < 0.05 ). In terms of family characteristics, parents not in marriage and living with (external) grandparents were negatively correlated with the total score and different types scores of percieved social support, while family characteristics such as satisfaction with family income (average, satisfactory, very satisfactory) and parents education level of junior high school and above were positively correlated with the total score and the different types scores of precieved social support ( B=-1.34--0.37, 0.57-2.37, P <0.05). In terms of school characteristics, without experience of bullying in school and the number of same sex or opposite sex friends >1 were positively correlated with the total score and different types scores of perceptual social support, and without serving as an officer of a student organization was negatively correlated with the total score and the different types scores of precieved social support ( B= 1.21- 5.04, -2.00--0.76, P <0.05). Conclusions The levels of overall and different types of precieved social support among vocational school students need to be improved. According to individual, family, and school related factors of precieved social support can help to target the improvement of students precieved social support level.
