OBJECTIVE To explore the improving effect of luteolin (Lut) on placental dysfunction in rats with gestational diabetes mellitus (GDM) and its potential mechanism based on hedgehog (Hh) signaling pathway. METHODS Twenty female rats were randomly selected as a control group and fed a normal diet. The remaining female rats were fed a high-fat and high-sugar diet for 8 weeks and then caged with male rats. Pregnant rats were administered 35 mg/kg streptozotocin intraperitoneally to establish GDM models. Successfully modeled female rats were randomly allocated to model group, SAG group (Hh signaling pathway activator SAG 50 mg/kg), Lut low-dose group (Lut 40 mg/kg), Lut high-dose group (Lut 80 mg/kg), and Lut high+ITR group (Lut 80 mg/kg+Hh signaling pathway antagonist itraconazole 50 mg/kg), with 20 rats in each group. Female rats in each drug group were intubated with the corresponding drug solution once a day for 19 days. After the final administration, the serum glucose- fat metabolic parameters (levels of fasting blood glucose and fasting insulin, insulin resistance index), placental quality, placental permeability [Evan’s blue (EB) content], and pathological changes in placental tissue were observed. The activities of superoxide dismutase (SOD), the contents of malondialdehyde (MDA) and reduced glutathione (GSH), and the protein expressions of Sonic Hh (Shh), Patched-1 (Ptch1), Smoothened (Smo) and Gli family zinc finger-1 (Gli1) in placental tissue were detected. HBB_ RESULTS Compared with the control group, rats in the model group showed narrow capillary lumens, perivascular fibrosis in placental tissue, and a significant increase in serum glucose-fat metabolic parameters, placental quality, contents of EB and MDA, while there was a significant decrease in SOD activity, GSH content, and protein expressions of Shh, Ptch1, Smo and Gli1 (P<0.05). Compared with the model group, rats in the SAG group, Lut low-dose and high-dose groups had widened capillary lumens, a significant decrease in perivascular fibrosis in placental tissue, serum glucose-fat metabolic parameters, placental qualities, EB and MDA contents, while there was a significant increase in SOD activities, GSH contents, and protein expressions of Shh, Ptch1, Smo and Gli1 (P<0.05), with the high-dose group showing no significant difference compared to the SAG group (P>0.05). The Hh signaling pathway antagonist itraconazole could significantly reverse the improving effects of Lut on the above indicators (P<0.05). CONCLUSIONS Lut can improve glucose metabolism parameters of GDM rats, reduce placental permeability, alleviate pathological damage to placental tissue, and reduce oxidative stress. These effects may be related to the activation of the Hh signaling pathway.

Objective:To translate the English version of the Beliefs Toward Mental Illness Scale (BTMI) into Chinese and test the reliability and validity of the Chinese version in college students.Methods:According to the Beaton cross-cultural adaptation guideline, the Chinese version of BTMI was formed. From April to May 2023, a questionnaire survey was conducted on 915 university students from 171 universities in 26 provinces, autonomous regions, and municipalities across China using convenience sampling, to analyze the reliability and validity of the scale.Results:A total of 915 questionnaires were distributed, and 814 valid questionnaires were collected, with an effective recovery rate of 88.96% (814/915). The Chinese version of BTMI had a total of 21 items. The Cronbach's α coefficient of the total scale was 0.922, and the Cronbach's α coefficients of each dimension were 0.745 to 0.921. The half reliability coefficient of the total scale was 0.797, and the retest reliability coefficient of the total scale was 0.903 ( P<0.01). Exploratory factor analysis extracted four common factors, namely social function, risk, incurability, and awkwardness, with a cumulative variance contribution rate of 62.29%. Confirmatory factor analysis showed that all important fitting indicators were greater than 0.900, indicating a good overall model fit. Conclusions:The Chinese version of BTMI has good reliability and validity, which can be used to evaluate the beliefs of Chinese university students about mental illness.

Objective:To investigate pathological features and differential diagnosis in the gonads with disorder of sex development.Methods:Thirty-six cases of clinically diagnosed hermaphroditism with gonadal biopsy in the Department of Pathology, the Seventh Medical Center of People′s Liberation Army General Hospital from April 2007 to July 2021, were collected. All biopsy pathological sections were reviewed, and the gonadal cases with abnormal pathological morphology were screened out. The clinical and imaging data and karyotype of these cases were reviewed. Additional immunohistochemical staining was performed and relevant literature was reviewed.Results:Seven cases of ovotesticular disorder of sex development (OTDSD) were identified, which were characterized by the presence of testicular and ovarian differentiation in the same individual. All patients were under 15 years old and presented with abnormal appearance of external genitalia, and the ratio of male to female was 2∶5. Ultrasonography showed testicular structure in all female patients and cryptorchidism in all male patients. The most common karyotype was 46, XX. One case with undifferentiated gonadal tissue (UGT) and one case with streak gonads were screened out. UGT germ cells were neither in seminiferous tubules nor in follicles, but randomly distributed in an ovarial-type interstitial background, sometimes accompanied by immature sex cords. Streak gonads resembled UGT without germ cells. FOXL2 was positive in granulosa cells, but negative in Sertoli cells. SOX9 expression was opposite. OCT4 was weakly positively/negatively expressed in oocytes and positively expressed in the germ nuclei of UGT.Conclusions:Four differentiation patterns need to be identified in the gonadal biopsy: ovarian differentiation, testicular differentiation, undifferentiated gonadal tissue and streak gonad. The positive expression of SOX9 indicates testicular differentiation, while the positive expression of FOXL2 confirms ovarian differentiation, and the expression of both markers in the same tissue indicates ovotestis differentiation. It is very important to identify UGT, because that has a high probability of developing into gonadoblastoma in the future.

Background:
At the therapeutic doses, diclofenac sodium (DFS) has few toxic side effects on mammals. On the other hand, DFS exhibits potent toxicity against birds and the mechanisms remain ambiguous.
Objectives:
This paper was designed to probe the toxicity of DFS exposure on the hepatic proteome of broiler chickens.
Methods:
Twenty 30-day-old broiler chickens were randomized evenly into two groups (n = 10).DFS was administered orally at 10 mg/kg body weight in group A, while the chickens in group B were perfused with saline as a control. Histopathological observations, serum biochemical examinations, and quantitative real-time polymerase chain reaction were performed to assess the liver injury induced by DFS. Proteomics analysis of the liver samples was conducted using isobaric tags for relative and absolute quantification (iTRAQ) technology.
Results:
Ultimately, 201 differentially expressed proteins (DEPs) were obtained, of which 47 were up regulated, and 154 were down regulated. The Gene Ontology classification and Kyoto Encyclopedia of Genes and Genomes pathway analysis were conducted to screen target DEPs associated with DFS hepatotoxicity. The regulatory relationships between DEPs and signaling pathways were embodied via a protein-protein interaction network. The results showed that the DEPs enriched in multiple pathways, which might be related to the hepatotoxicity of DFS, were “protein processing in endoplasmic reticulum,” “retinol metabolism,” and “glycine, serine, and threonine metabolism.”
Conclusions
The hepatotoxicity of DFS on broiler chickens might be achieved by inducing the apoptosis of hepatocytes and affecting the metabolism of retinol and purine. The present study could provide molecular insights into the hepatotoxicity of DFS on broiler chickens.
