Objective:To investigate the level of serum vascular endothelial growth factor (VEGF) and its correlation with clinical symptoms in patients with first-episode drug-naive schizophrenia patients of different genders.Methods:From January 2016 to October 2019, a total of 81 first-episode drug-naive schizophrenia patients(patient group, 41 male, 40 female) and 64 healthy controls (control group, 40 male, 24 female) were included in this study.The serum level of VEGF was detected with flow cytometric bear array (CBA). Positive and negative symptom scale (PANSS) was used to evaluate the relevant clinical symptoms of patients.SPSS 22.0 software was used for statistical analysis.Independent sample t-test and nonparametric test were used for comparison between groups.The relationship between VEGF and clinical variables was analyzed by Pearson correlation analysis and Spearman correlation analysis. Results:The level of serum VEGF in the patient group was significantly lower than that in the control group(148.08(75.89, 208.61)pg/mL, 179.94(99.14, 318.41)pg/mL, Z=-2.20, P=0.028). The total PANSS score((82.71±17.30), (73.45±16.36), t=2.473, P=0.016)and cognitive score((7.88±3.36), (6.23±2.81), t=2.402, P=0.019) in male patients were higher than those in female patients.There was a negative correlation between VEGF level and PANSS negative symptom score in the patient group( r=-0.228, P=0.041), as well as significant negtive correlation between VEGF level and cognitive score in male patients( r=-0.425, P=0.007). Conclusion:The level of serum VEGF is reduced in first-episode patients with schizophrenia, which influences their negative symptom. Moreover, the decline in serum VEGF level is implicated in cognitive impairments in male patients with first-episode schizophrenia.

Purpose: Screening for hepatocellular carcinoma (HCC) as an effective instrument to reduce the burden of late diagnoses remains underutilized in China, much of the Asian countries, and in a sense all over the world. Modifiable psychosocial factors should be identified to improve screening utilization and reduce the burden of late diagnoses. However, valid psychosocial measures are unavailable. This study aimed to translate, culturally adapt, and validate the preventive health model (PHM) instrument for measuring psychosocial factors of HCC screening among patients with hepatitis B. Methods: This study was conducted from June 2020 to April 2021 in three rigorous phases: (1) committee-based translation from English to Chinese; (2) cognitive interviews (n = 33) and Delphi expert consultations (n = 7) for cultural adaptation; and (3) a cross-sectional study (n = 305) for validation. Results: In phase I, two items were reworded, and two retranslated for semantic equivalence. In phase II, issues related to comprehension, sensitive wording, wording clarity, question relevance, and cultural sensitivity were addressed by including pictures, rewording five items, and developing seven items. In phase III, exploratory and confirmatory factor analyses suggested a five-factor 20-item solution: it explained 76.9% of the variance; had adequate factor loading (.60–.91), convergent and discriminant validity; satisfactory model fit indices; and reliability (Cronbach's α, .86−.91). Known-group analysis showed that patients with optimal HCC screening behavior had significantly higher scores on each subscale than those not having such. Conclusion The Chinese PHM instrument is culturally sensitive, reliable, and valid to measure the psychosocial factors of HCC screening. It can help nurses and researchers to tailor strategies to improve clinical HCC screening practices in high-risk HCC regions.

Objective:To investigate the changes and to establish a reference interval of bile acid profile of healthy pregnant women in the second and third trimesters of pregnancy in our hospital.Methods:A total of 298 healthy singleton pregnant women who underwent prenatal examination in the Department of Obstetrics of Zhejiang Provincial People′s Hospital from July 2019 to August 2020 were enrolled in this study. The overnight fasting serum samples were collected from all subjects during their second and third trimesters of pregnancy. The concentrations of 15 bile acids(cholic acid, chenodeoxycholic acid, deoxycholic acid, ursodeoxycholic acid, lithocholic acid and their glycine-and taurine-conjugated types)were analyzed by liquid chromatography tandem mass spectrometry (LC-MS/MS). The characteristics of changes were analyzed and the reference intervals were determined for the second and third trimesters. The concentrations of 15 bile acids and total bile acids were skewed-distributed, and 99 percentiles (P 99) were used to represent the unilateral upper limit of the reference interval. Results:There was significant difference in the serum levels of glycine cholic acid (GCA), taurocholic acid (TCA), glycine ursodeoxycholic acid (GUDCA) and lithocholic acid (LCA) between the second and third trimesters healthy pregnant females ( P<0.05). For other 11 bile acids, there was no significant difference. The levels of total bile acids, primary or secondary bile acids, free or conjugated bile acids (glycine-bound and taurine-bound bile acids) were stable with gestation. Conclusion:Primary, secondary or free, and conjugated bile acids in healthy pregnant women remained stable at T 2 and T 3, with significant differences in only a few subtypes of bile acids. While the correlation between glycine-bound and taurine-bound bile acids showed a weakening trend at T 3 ( P<0.05). It is necessary to establish reference intervals of bile acids for healthy pregnant women in this area. This study provided data support for future research on related diseases during pregnancy.

OBJECTIVE: To explore the risk factors of anxiety and depression in patients with suspected coronavirus disease 2019 (COVID-19) so as to achieve early intervention and better clinical prognosis. METHODS: Seventy-six patients with suspected COVID-19 in fever isolation wards of Second Hospital of Lanzhou University were enrolled From January 31, 2020 to February 22, 2020. Their clinical baseline data were collected. The anxiety of patients was assessed by Hamilton Anxiety Scale, and the depression of patients was assessed by Hamilton Depression Scale. Multivariate Logistic regression analysis was performed to explore the risk factors of anxiety and depression in these patients. RESULTS: Female patients are more likely to have anxiety (=3.206, 95%: 1.073-9.583, <0.05) and depression (=9.111, 95%: 2.143-38.729, <0.01) than male patients; patients with known contact history of epidemic area and personnel in epidemic area are more likely to have depression (=3.267, 95%: 1.082-9.597, <0.05). CONCLUSIONS During the isolation treatment of suspected COVID-19 patients, early psychological intervention should be carried out for the female patients with known contact history of epidemic area and personnel in epidemic area, and drug treatment should be given in advance if necessary.

Objective:To analyze the expression of LETM2 in KYSE150 and ECA109 cell lines and its effect on the proliferation, migra-tion, and invasion of esophageal squamous cell carcinoma (ESCC). Methods:The expression level of the LETM2 protein in 90 paired hu-man ESCC tissues and matched adjacent normal tissues was determined through immunohistochemistry. The expression level of LETM2 in ESCC cell lines was detected by real-time PCR and Western blot. The expression levels of LETM2 in KYSE150 and ECA109 cell lines were knocked down using lentivirus. MTT assays were performed to examine the effect of LETM2 on the proliferation of ESCC cells. Colony formation assay was used to detect the colony formation ability. Flow cytometry was performed to analyze the cell cycle. The effect of LETM2 depletion on the migration and invasion of ESCC cells was determined by Transwell assay. Results:LETM2 expres-sion was frequently upregulated in the ESCC tissues than in the adjacent normal tissues. The suppressed exogenous expression of LETM2 led to the inhibition of cell proliferation and colony formation. However, cell migration and invasion were not affected. The re-sults on the cell cycle distribution revealed that LETM2 knockdown acts as a negative regulator of the cell cycle at the G1 to S phase transition. Conclusion:LETM2 acts as a tumor-driven gene in the development and progression of ESCC. This finding suggests that LETM2 can be used as an efficient prognosis biomarker and a potential therapeutic target for ESCC.

Objective:To analyze the expression of MUC15 and PI3K/Akt in gastric carcinoma and its association with clinicopathologi-cal characteristics and prognosis. Methods:The expression of MUC15 and Akt was detected in 144 cases of gastric carcinoma tissues and corresponding para-carcinoma tissues by tissue microarray and immunohistochemistry. Results:The positive expression rate of MUC15 in gastric carcinoma was 79.8%, higher than that of para-carcinoma tissues (22.2%, P<0.01). The positive expression rate of Akt protein in gastric carcinoma was 80.6%, higher than that of para-carcinoma tissues (16.7%, P<0.01). The expression of MUC15 and Akt was statistically associated with the grades of differentiation, invasion depth, lymphatic metastasis, TNM stage of tumor tissues (P<0.05), and the positive correlation between the two protein expression that appear in the gastric tumor tissue (P=0.001). Univariate survival analysis showed that the over-expression of either MUC15 or Akt was inversely correlated with the survival time (P<0.05 and P<0.01, respectively). Cox multiple regression analysis indicated that patients with over-expression of both MUC15 and Akt had the worst prognoses (HR=3.115, P<0.05). Conclusion:MUC15 may be involved in the occurrence, development, invasion, and metastasis of gastric cancer through the PI3K/Akt cell signaling pathway, and the expression of MUC15 combined with Akt is a powerful predictor for the prognosis of gastric cancer.

OBJECTIVEThe term "premature thelarche" refers to isolated breast development before 8 years of age in female, without any other signs of sexual maturation, while "gynecomastia" is the presence of breast tissue in males. This study aimed to investigate the prevalence of premature thelarche and gynecomastia in Chinese infants and toddlers, identify the potential risk factors, and explore the influence of early breast development on physical growth, mental development and psychomotor development.

METHODA total of 1 510 full term and healthy children at the age of 0-48 months were sampled by stratified cluster random sampling method from 8 provinces from 2011-2012. Weight, height and breast development were assessed by senior primary pediatricians, while Bayley Scale of Infant Development-I (BSID-I) was used to measure the mental developmental index (MDI) and psychomotor developmental index (PDI) for children aged 2-30 months. Social-demographic Questionnaires were completed by the caregivers.

RESULTThe combined prevalence of premature thelarche and gynecomastia was 1.6% (23/1 475), girls 2.2% (15/695), boys 1.0% (8/780), all within 2 years of age. The birth weight, feeding patterns in first 4 months, delivery mode, weaning time and social economic status were not significantly associated with the breast development. However, lower father's education level (OR = 3.632, 95%CI = 1.565-8.432) as well as smoking mother (OR = 18.960, 95%CI = 1.590-226.304) were significantly related to breast development even after adjusting for potential confounders. Lower weight (-0.479 ± 0.648 vs. 0.005 ± 0.987, P < 0.05) and height (-0.602 ± 1.042 vs. 0.008 ± 0.986, P < 0.05) Z score were found in breast development group, even after adjusting for age, gender and father' education level. Neither mental development (t = -0.082, P > 0.05) nor psychomotor development (t = 1.054, P > 0.05) was associated with breast development.

CONCLUSIONWe showed a similar prevalence of premature thelarche with the data reported in similar studies reported from other countries. Among the 0-48 months old infants and toddlers, Father's education level and smoking mother were both related to breast development. Breast development was significantly associated with physical growth, but had no correlation with the mental or psychomotor development.
