Objective: To explore the relationship between depression, anxiety, stress and food addiction among primary and secondary school students in Yixing City, so as to provide reference and suggestions for maintaining healthy eating behavior and psychological health intervention and promotion among primary and secondary school students in Yixing City. Methods: From December 2022 to February 2023, a stratified cluster random sampling method was used to select 4 180 primary and secondary school students from four primary and secondary schools in Yixing City, Jiangsu Province. A questionnaire survey was conducted using the Depression Anxiety Stress Scale-21 (DASS-21) and related behavior questionnaires. The data was analyzed using χ 2 test, Wilcoxon, Kruskal Wallis H rank sum test, and binary Logistic regression. Results: The prevalence of food addiction among primary and secondary school students in Yixing City was 0.98% (41 students), and there was no statistically significant difference in the comparison of food addiction, depression, anxiety, and stress scores among students of different genders and age groups ( Z/H = -1.34- 5.74, P >0.05). There was a positive correlation between food addiction and binge eating behavior, depression, anxiety, and stress symptoms ( r=0.14-0.23, P <0.01). The results of binary Logistic regression showed that anxiety ( OR=5.68, 95%CI =1.74- 18.55 ) and stress ( OR=5.41, 95%CI =2.20-13.32) were positively correlated with the occurrence of food addiction in primary and secondary school students ( P <0.01). Conclusions The risk of food addiction among primary and secondary school students with anxiety and stress symptoms is higher than that of the general population. Guidance and intervention on student mental health should cover the entire compulsory education and high school period, in order to improve the mental health level of students and reduce the occurrence of food addiction behavior.

OBJECTIVE: To explore the regulatory role of COX-2 and aggregation of EOS in the pathogenesis of Aspirin triad syndrome. METHOD: There were 34 patients with ST (group 1), 30 patients with chronic sinusitis and nasal polyps and asthma (group 2), 30 patients with sinusitis (control group). Nasal polyps of 94 patients were obtained in endoscopic sinus surgery,HE staining and immunohistochemical SP staining were performed to detect the distribution of eosinophils(EOS) and the expression of COX-2. Statistical analysis was performed using the SPSS software and then the relationship between their expression and distribution with clinical pathology and pathogenesis was analyzed. RESULT: EOS infiltrated extensively in nasal polyps, and EOS counts in these groups were 80.02 +/- 6.11, 76.62 +/- 5.22, 65.97 +/- 4.78,respectively. The difference between ST group, ATA group and control group are significant (P < 0.05), no significant difference between ST group and ATA group. COX-2 in the nasal polyps was mainly expressed in submucosal glands, glandular epithelial cells, epithelial cells, endothelial cells and EOS in interstitium. The positive cell count were 88.13 +/- 6.26, 89.46 +/- 5.97, 91.22 +/- 4.11, respectively. There was significant difference (P < 0.05) between ST group and control group. No significant difference (P > 0.05) was found between ATA group and control group,ST group and ATA group. CONCLUSION The difference of EOS infiltration in patients with ST may be associated with an inflammatory response underlying specific clinical manifestations after exposure to non-steroidal anti-inflammatory drugs, and the difference of COX-2 expression in patients with ST may be related to the conversion of metabolic pathway of arachidonic acid and the formation of nasal polyps.

OBJECTIVETo detect mutation of GPR143 gene in a Chinese patient affected with ocular albinism.

METHODSPeripheral blood samples were collected from the proband and his parents. The coding regions of the GPR143 gene were subjected to PCR amplification and Sanger sequencing.

RESULTSA previously unreported mutation (c.758T>A) was found in exon 6 of the GPR143 gene in the proband and his mother. The same mutation was not found in his father. As predicted, the mutation has resulted in a stop codon, causing premature termination of protein translation.

CONCLUSIONA novel mutation of the GPR143 gene related to X-linked ocular albinism has been identified.

Objective:To investigate the clinicopathological, immunohistochemical and molecular genetic characteristics of TFE3-rearranged perivascular epithelioid cell tumor (PEComa).Methods:Eight cases of PEComa with TFE3 rearrangement diagnosed in the First Affiliated Hospital of Air Force Medical University from January 2014 to July 2022 were collected. Three were consultation cases and 5 were collected from our hospital; 7 cases were resection specimens and 1 case was a needle biopsy specimen. Routine histolopathological analysis, immunohistochemical staining, fluorescence in situ hybridization (FISH) and the next-generation sequencing were performed. Clinical data were collected and the prognosis was assessed.Results:The 8 patients consisted of 5 females and 3 males with a median age of 45 years (ranged from 25 to 65 years). The tumor location included 1 uterus, 1 liver, 1 urachus, 2 kidneys, 1 abdominal cavity, 1 colon, and 1 retroperitoneum (3 subsequent recurrences in the abdominal cavity, pelvis and ovary, and abdominal cavity, respectively). Morphologically, the tumor cells were uniform and epithelioid with translucent or eosinophilic cytoplasm. They were arranged in nests or sheets, most of which were separated by thin-walled blood vessels. There were no papillary structures, and no overt smooth muscle or fat components. Atypical features were seen in 3 cases, with bizarre nuclei and tumor giant cells. Large areas of necrosis were visible, and mitosis was common (up to 28/50 HPF). Melanin deposition was present in 3 cases. Immunohistochemical staining showed diffuse and strong positivity for TFE3 in 8/8 cases and for HMB45 in 6/8 cases; focal positivity for Cathepsin K and Melan-A in 6/8 cases and for SMA in 2/8 of cases. All cases were negative for CKpan, PAX8 and Desmin. TFE3 gene break-apart was detected by FISH in all 8 cases, 4 of which underwent next-generation sequencing, and it revealed that 2 cases presented with SFPQ::TFE3 fusion, 1 case with ASPSCR1::TFE3 fusion, and 1 case with no chimeric fusion. Seven cases were followed up for 4—94 months. All cases were alive; 4 cases were disease-free, 2 cases showed recurrence, and 1 case had metastasis at initial diagnosis.Conclusions:TFE3-rearranged PEComa has unique histomorphological, immunohistochemical and molecular characteristics. The biological behavior is aggressive, which could lead to recurrence and metastasis, and warrants close clinical follow-up.

Objective:To evaluate the efficacy and safety of oliceridine for treatment of moderate to severe pain after surgery with general anesthesia in patients.Methods:The patients with moderate to severe pain (numeric pain rating scale ≥4) after abdominal surgery with general anesthesia from 14 hospitals between July 6, 2021 and November 9, 2021 were included in this study. The patients were assigned to either experiment group or control group using a random number table method. Experiment group received oliceridine, while control group received morphine, and both groups were treated with a loading dose plus patient-controlled analgesia and supplemental doses for 24 h. The primary efficacy endpoint was the drug response rate within 24 h after giving the loading dose. Secondary efficacy endpoints included early (within 1 h after giving the loading dose) drug response rates and use of rescue medication. Safety endpoints encompassed the development of respiratory depression and other adverse reactions during treatment.Results:After randomization, both the full analysis set and safety analysis set comprised 180 cases, with 92 in experiment group and 88 in control group. The per-protocol set included 170 cases, with 86 in experiment group and 84 in control group. There were no statistically significant differences between the two groups in 24-h drug response rates, rescue analgesia rates, respiratory depression, and incidence of other adverse reactions ( P>0.05). The analysis of full analysis set showed that the experiment group had a higher drug response rate at 5-30 min after giving the loading dose compared to control group ( P<0.05). The per-protocol set analysis indicated that experiment group had a higher drug response rate at 5-15 min after giving the loading dose than control group ( P<0.05). Conclusions:When used for treatment of moderate to severe pain after surgery with general anesthesia in patients, oliceridine provides comparable analgesic efficacy to morphine, with a faster onset.
