OBJECTIVE To explore the relationship between the ANKK1 rs1800497 polymorphism and atypical antipsychotic drug-induced metabolic syndrome （MS）. METHODS Totally 94 patients with schizophrenia were included， and ANKK1 rs1800497 genotypes of patients were detected by micro-fluorescence immunoassay； social demographic information， clinical characteristics and other data were collected. The χ2 test was used to compare the correlation between the sex of patients and the occurrence of MS， and the correlation between gene polymorphism and the occurrence of MS and its risk factors.RESULTS Totally 94 patients included 24 cases （25.53%） of GG， 51 cases （54.26%） of GA and 19 cases of AA （20.21%）. Among them， there were 45 cases （47.87%） of MS， and the incidence of MS in male was higher than that in female （P＜0.05）. Genotype analysis showed that ANKK1 rs1800497 polymorphism was not associated with MS （P＝0.452）. ANKK1 rs1800497 A allele was significantly associated with hyperglycemia （χ2＝4.379， P＝0.036）， while it was not related to abdominal obesity， hypertension， high level of TG and low level of HDL-C （P＞0.05）， suggesting that for patients with schizophrenia， allele A was a relative risk factor for inducing hyperglycemia [OR＝2.008，95%CI（1.039， 3.881）]. CONCLUSIONS ANKK1 rs1800497 polymorphism has no correlation with the induction of MS by atypical antipsychotics， while the schizophrenia patients with A allele are more likely to induce hyperglycemia. The incidence of MS in male patients is significantly higher than that in female patients.

BackgroundAssisted reproductive technology is increasingly mature and widely used in clinic. As more and more newborns are born with assisted reproductive technology， the health problems of these newborns also need more attention. ObjectiveTo investigate the effects of assisted reproductive technology on newborn physique and autistic behavior， and to raise the attention of autistic behavior of assisted reproductive children. MethodsFrom the medical record information system， 588 assisted reproduction newborns （assisted reproduction group） born in the obstetrics department of Chaohu Hospital of Anhui Medical University from August 2018 to August 2019 were selected as the study objects. From the medical records information system， 600 newborns born naturally in the obstetrics department in the same period of time were selected as the control group. The basic information of all newborns was collected， including the mother's age and years of education， sex， gestational age， birth weight and birth length， and they were assessed by the Clancy Autism Behavior Scale （CABS） at 3 years of follow-up. ResultsThe educational years of mothers in assisted reproduction group were longer than those in control group ［（12.04±1.96） years vs. （11.34±2.90） years， t=-4.887， P<0.01］， gestational age and birth weight of assisted reproduction group were lower than those of control group ［（38.68±2.56） weeks vs. （39.53±2.91） weeks， t=5.315， P<0.01； （3 273.27±720.39） g vs. （3 158.29±701.74） g， t=2.792， P<0.05］. There was no significant difference in birth length between the two groups ［（49.97±5.94） cm vs. （50.07±6.08） cm， t=-0.287， P>0.05］. At the age of three， the weight and height of the assisted reproduction group were both lower than those of the control group ［（16.16±2.53）kg vs.（16.96±1.67）kg， t=6.393， P<0.01， （95.81±4.50）cm vs.（97.47±7.49）cm， t=4.626， P<0.01］. Respectively， 6 （1.00%） and 15 （2.55%） children with autism were detected in the control group and assisted reproduction group， and the difference was statistically significant （χ²=4.113， P<0.05）. ConclusionAssisted reproductive technology may affect the physical and neurological development of children. ［Funded by Outstanding Young Talents Support Program of Anhui Education Department （number， gxyqZD2022022）］

Objective: To study the expression and clinical significance of Vimentin and E-cadherin in human breast cancer tissues. Methods: : The clinical data of 56 cases of breast cancer patients, who underwent radical mastectomy in Chaohu Hospital Affiliated to Anhui Medical University from January 2014 to January 2016, were retrospectively analyzed. The protein and mRNAexpressions of Vimentin and E-cadherin in breast cancer tissues were detected by immunohistochemistry and qPCR, respectively; and the relationship between the expression of Vimentin and E-cadherin in breast cancer tissues and the clinicopathological characteristics was analyzed. Logistic multivariate regression was used to analyze the independent factors affecting the protein expressions of Vimentin and E-cadherin. Spearman was used to analyze the correlation between Vimentin and E-cadherin. Kaplan-Meier was used to analyze the relationship between protein expressions of Vimentin, E-cadherin and prognosis. ROC curve was used to analyze the diagnostic value of Vimentin and E-cadherin on prognosis. Results: The rates of breast cancer tissues with high positive expression of Vimentin and E-cadherin were 76.79% and 19.64%, respectively.Among them, 47 cases (47/56, 83.93%) of breast cancer tissues showed significantly higher Vimentin mRNA expression than adjacent tissues (P<0.05), and 46 cases (46/56, 82.14%) of breast cancer tissues showed significantly lower Ecadherin mRNA expression than adjacent tissues (P<0.05). Vimentin protein expression was associated with tumor size, lymph node metastasis, vascular invasion, histological grade, clinical stage, molecular typing, Ki67+, ER-, PR- and HER2- expression (P<0.05). And E-cadherin protein expression was associated with lymph node metastasis, vascular invasion, histological grade, clinical stage, molecular typing, Ki67+, ER-, PR- and HER2- expression (P<0.05). Tumor size, lymph node metastasis, vascular invasion, histological grading, clinical staging, molecular typing, Ki67+, ER-, PR- and HER2- expression were all independent factors affecting the expression of Vimentin and E-cadherin (P<0.05). There was a negative correlation between Vimentin and E-cadherin expression (P<0.05). The 3-year survival rate of patients with high expression of Vimentin protein was 67.44%, while that of patients with low expression of E-cadherin protein was 68.89%. Conclusion: The high expression of Vimentin and low expression of E-cadherin in breast cancer tissues may be related to the occurrence, development, invasion and metastasis of breast cancer. It can be used as a reliable indicator of clinical diagnosis and prognosis.

Objective To summarize clinical characteristics of infradiaphragmatic craniopharyngioma and explore its prognosis factors. Methods The clinical date, imaging and follow-up findings were analyzed retrospectively in 58 pa?tients with infradiaphragmatic craniopharyngioma who underwent surgical operation in our hospital. Factors related to the postoperative quality of life of patients were analyzed using multi-factors Logistic regression analysis. Results There were 45 minor cases with infradiaphragmatic craniopharyngioma, of which forty cases (88.9%) had preoperative visual im?pairment. Preoperative endocrine examination revealed that 21 cases (46.7%) had pan-hypopituitarism and 24 cases (53.3%) had pari-hypopituitarism. In addition, preoperative MRI showed that 38 cases (84.4%) had tumor involvement in/on the saddle and the average tumor size was(4.53 ± 1.71)cm. There were 13 adult cases, of which 8 cases (61.5%) had preoperative visual impairment. Only 1 case (15.4%) had pan-hypopituitarism, 7 cases had pari-hypopituitarism and 5 cases had normal pituitary function. Ten cases (76.9%) had tumor involvement in/on the saddle and average tumor size was(2.92 ±1.18)cm. Multi-factors Logistic regression analysis revealed the patient's age (OR=0.090, P=0.090) and tu?mor size (OR=8.350, P=8.350), preoperative vision loss (OR=0.086, P=0.086), preoperative hypopituitarism (OR=0.198, P=0.198) were the relative factors affecting the quality of life. Conclusion Infradiaphragmatic craniopharyngioma is
more common in minor patients. The clinical features and prognosis are significantly different between minor patients and adult patients. Age, size of tumors, preoperative vision loss and hypopituitarism of patients are associated with poor prog?nosis.

Objective : To investigate the protective effect and related mechanisms of dexmedetomidine (Dex) on iron overload toxicity in mouse hippocampal neurons (HT22) induced by ferric ammonium citrate (FAC) . Methods: Selected HT22 cells in good condition were randomly divided into 4 groups: control group ( Ctrl group), FAC treatment group (FAC group), Dex treatment group (Dex group), ferroptosis inhibitor Fer⁃1 treatment group (Fer1 group) . The iron overload model was established by FAC⁃induced cells . Subsequently, the proliferation and survival rate of HT22 cells was detected by CCK⁃8 method; Western blot was used to detect the ferroptosis marker proteins prostaglandin⁃endoperoxide synthase 2 ( PTGS2 ) and acyl⁃CoA synthetase long⁃chain family member 4 (ACSL4) . The protein expressions of mammalian target of rapamycin ( mTOR), transferrin receptor 1 ( TFR1) and ferroportin (Fpn); the gene expression levels of PTGS2 and ACSL4 in HT22 cells were detected by qPCR; Reactive oxygen species (ROS) levels in HT22 cells was detected by DHE fluorescent probe; MDA detection kit was used to detect lipid oxidation levels in HT22 cells; Mito⁃FerroOrange—ferrous ion probe was used to detect ferrous ion levels in HT22 cells; electron microscopy was used to detect intracellular ultrastructural changes . Results: Dex group and Fer⁃1 group significantly decreased cell death rate after 2 h of pretreatment, the protein and gene expression levels of ferroptosis markers PTGS2 and ACSL4 significantly decreased . The degree of cell ultrastructural damage was significantly improved . The levels of ROS, lipid oxidation and Fe2 + were significantly lower than those of the FAC group (P < 0. 05) . Conclusion Dex pretreatment can attenuate FAC⁃induced iron overload toxicity in⁃ jury in HT22 cells, which may be related to the inhibition of ferroptosis .

Objective To evaluate the expression and clinical significance of Periostin (POSTN) in craniopharyngi?oma. Methods Forty-two patients with pathologically diagnosed adamantinomatous craniopharyngioma involving the floor of 3rd ventricle were retrospectively analyzed. The correlation between expression of POSTN and outcome was studied. Results POSTN was expressed in stroma of craniopharyngioma tissues. The expression of POSTN was not associated with the postoperative recurrence (Z=-0.236,P=0.813) while was associated with the degree of the adhesion between tumor and floor of 3rd ventricle (r=0.685, P<0.001), postoperative Hypothalamic Status Scale (r=0.569, P<0.001) and Body Mass Index (r=0.594, P<0.001). Conclusions POSTN may predict the degree of the adhesion between craniopharyngioma and 3rd ventricle floor. The high expression of POSTN may indicate the worse hypothalamus function.

ObjectiveTo investigate the value of gamma-glutamyl transpeptidase (GGT)/albumin (Alb) ratio in the noninvasive diagnosis of liver fibrosis degree in patients with chronic hepatitis B virus (HBV) infection. MethodsA retrospective analysis was performed for the clinical data of 322 patients with chronic HBV infection who underwent liver biopsy in Chaohu Hospital of Anhui Medical University from January 2018 to March 2020, and according to liver fibrosis degree based on liver biopsy, the 322 patients were divided into S0-S1 group with 183 patients, S2 group with 68 patients, S3 group with 35 patients, and S4 group with 36 patients. The clinical indices of routine blood test, virology, and blood biochemistry were collected. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the Kruskal-Wallis H test was used for comparison of non-normally distributed continuous data between multiple groups; the chi-square test was used for comparison of categorical data. A Spearman rank correlation analysis was used to investigate the correlation of the three noninvasive models GGT/Alb ratio, aspartate aminotransferase-to-platelet ratio index (APRI) score, and fibrosis-4 (FIB-4) index with liver fibrosis degree. A receiver operating characteristic (ROC) curve was plotted for GGT/Alb ratio to evaluate its diagnostic value. ResultsWith the aggravation of liver fibrosis degree, there were gradual reductions in Alb (F=7351, P＜0.05), HBV DNA (χ2=2.820, P＜0.05), and platelet count (F=6.182, P＜0.05) and gradual increases in age (χ2=3145, P＜0.05), GGT (χ2=6.149, P＜0.05), GGT/Alb ratio (χ2=7.064, P＜0.05), APRI score (χ2=9.022, P＜0.05), and FIB-4 index (χ2=8.254, P＜0.05). The Spearman rank correlation analysis showed that GGT/Alb ratio was positively correlated with liver fibrosis stage (r=0.396, P＜0.01), with a significantly higher correlation coefficient than APRI score (r=0.327, P＜0.001) and FIB-4 index (r=0.370, P＜0.001). The ROC curve analysis showed that in the patients with significant liver fibrosis, severe liver fibrosis, and liver cirrhosis, GGT/Alb ratio had similar areas under the ROC curve to APRI score and FIB-4 index (0.680/0.676/0.695 vs 0692/0.698/0.728 and 0.659/0.661/0.684, all P＞0.05). At the optimal cut-off values of 0.435, 0.465, 0.465, respectively, GGT/Alb ratio had sensitivities of 69.1%, 66.2%, and 69.0%, respectively, and specificities of 65.4%, 65.9%, and 67.0%, respectively, in the diagnosis of significant liver fibrosis, severe liver fibrosis, and liver cirrhosis. ConclusionLike APRI score and FIB-4 index, GGT/Alb ratio is a simple and practical noninvasive model for the diagnosis of liver fibrosis and can provide a reference for the diagnosis of liver fibrosis degree in patients with chronic HBV infection.

Aim To investigate the effect of esketamine(ESK)on lipopolysaccharide(LPS)-induced damage to HT22 cells(mouse hippocampal neuron cells)and the underlying mechanism. Methods After ESK pretreatment for 2 h and then LPS treatment for 24 h, Western blot was used to detect high mobility group box-1(HMGB1), long chain acyl CoA synthetase 4(ACSL4), prostaglandin-endoperoxide synthase 2(PTGS2), transferrin receptor 1(TFR1), ferroportin(FPN)and ferritin expression. ELISA was used to detect the expression of inflammatory protein interleukin-1β(IL-1β)and tumor necrosis factor-α(TNF-α). DHE fluorescent was probed to detect the changes in intracellular reactive oxygen species(ROS). MDA kit was used to detect intracellular lipid oxidation levels. FerroOrange fluorescent was probed to detect intracellular divalent iron ion levels. Electron microscopy was used to observe the changes in mitochondrial ultrastructure. Results Compared with the normal group, the levels of ROS, lipid peroxidation and Fe

Objective: To explore the relationship between insulin resistance and plasma hypersensitive reactive protein (hs-CRP) in patients with chronic schizophrenia. Methods: A total of 247 inpatients with chronic schizophrenia (patient group) and 166 cases of normal individuals(control group) were enrolled.Their general demographic and clinical data were collected, fasting blood glucose, hs-CRP, c-peptide and insulin indexes were tested, and insulin resistance index (HOMA-IR) was calculated.The insulin resistance level of the patients group and the control group was compared by Mann-Whitney U test, and the relationship between insulin-resistance and hs-CRP in patients group was analyzed using Spearman correlation analysis. Results: (1)The levels of C-peptide (2.53(2.06, 3.23)ng/ml vs 2.24(1.89, 2.87)ng/ml), insulin (7.68(4.66, 11.97)μIU/ml vs 7.02(4.31, 9.59)μIU/ml) and HOMA-IR (1.75(1.09, 3.07) vs 1.57(0.97, 2.22)) in the patient group were significantly higher than those in the control group(all P<0.05). (2) The levels of HOMA-IR( 1.91(1.21, 3.74) vs 1.70(1.02, 2.72)) in patients with high hs-CRP(≥3 mg/L) was higher than those in the patients with low hs-CRP(<3 mg/L)(P<0.05). (3)Spearman correlation analysis showed that HOMA-IR was positively correlated with plasma hs-CRP level in the patient group (r=0.139, P<0.05). (4)After logarithmic transformation of related variables, multivariate linear regression analysis showed that HOMA-IR was linearly correlated with hs-CRP level and boy weight index. Conclusion The hs-CRP level in chronic schizophrenia has a positive predictive effect on insulin resistance.Detection of hs-CRP level in schizophrenic patients is helpful to assess metabolic risk of insulin.
