Objective To investigate cognitive function and behavior characteristics in the childhood onset schizo?phrenia patients with or without obsessive-compulsive symptoms. Methods One hundred forty-nine schizophrenia chil?dren were recruited and 72 healthy children served as children control group. According to the Schedule for Affective Dis?orders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL), the patients were fur?ther divided into two groups, the children with obsessive-compulsive disorder group (70 cases) and the children without obsessive-compulsive disorder group (79 cases). All the children were retrospectively surveyed and the Achenbach’s Child Behavior Check-list (CBCL) was used to assess their social competence and behavioral characteristics at the age from 6-year-old to 10-year-old. The cognitive function was estimated with WISC, STROOP color and word test, trail making test, visal spatial memory test and maze test. Results Compare to the control group, the CBCL factor scores of behavior problems were higher (P<0.01), social ability factor scores were lower (P<0.05) and all factor scores in the cog?nitive function tests were lower (P<0.05) in the two patients groups. Compare to the patients without obsessive-compul?sive symptoms, the CBCL factor scores of the school situation (P<0.01), splitting force (P<0.01), and physical complaints (P<0.01) were significantly higher and the scores were significantly lower in the test of common sense (P<0.01), wood (P<0.01), STROOP (P<0.01) and BVMT-R (P<0.01) in those with obsessive-compulsive symptoms. Correlation analysis showed that social competence total scores were positively correlated with similarity in the patients with obsessive-com?pulsive symptoms (r=0.31, P<0.01);while behavior problems total scores were negatively correlated with wood (r=-0.31, P<0.01) and patchwork (r=-0.32, P<0.01) in the patients without obsessive-compulsive symptoms. Conclusion The schizophrenia children with obsessive-compulsive symptoms have more behavioral problems in pre-symptom period and their cognitive dysfunction are more severe following onset of the disease. Cognitive function is related to behavioral prob?lems and social competence in the schizophrenia children with or without obsessive-compulsive symptoms .

OBJECTIVETo investigate whether myocardial bridging (MB) is an independent risk factor for coronary atherosclerosis proximal to the bridge site in the left anterior descending coronary artery (LAD) in diabetic patients.

METHODSFrom March 2011 to December 2012, 9862 patients with suspected coronary disease underwent coronary computed tomography angiography (CCTA) using a dual-source CT scanner. The baseline clinical characteristics (age, gender, smoking history, presence of hypertension, dyslipidemia, diabetes mellitus, family history of heart attack and body mass index) and the results of CCTA were reviewed. Two radiologists evaluated the MB and coronary atherosclerosis stenosis (CAS) over 50% in the LAD and made a diagnosis by consensus. Significant independent risk factors for CAS were investigated by logistic regression analysis.

RESULTSOf the 2345 patients identified to have diabetes mellitus, 1373 had MB, among whom 827 had coronary atherosclerosis proximal to the bridge site; 972 of the diabetic patients were free of MB, among whom 254 had coronary atherosclerosis at the equivalent site. None of the patients had CAS in the tunneled segment. After adjusted for clinical data, logistic regression analysis showed that MB in the LAD was significantly correlated with coronary atherosclerosis in the proximal LAD in diabetic patient (OR=3.91) and non-diabetic patients (OR=2.69) (P<0.05).

CONCLUSIONIn diabetic patients, atherosclerosis occurred frequently in the segment proximal to MB in the LAD, and MB in the mid-LAD is an independent risk factor for CAS in the proximal LAD.

Objective: The objective of this study was to present the real-world patients’ portrait, and the results of niraparib treatment in China. Methods: This study included 142 patients treated with niraparib from 8 hospitals in China between December 2018 and September 2021. Patients’ characteristics were summarized. The efficacy and safety in first-line maintenance (1L-M), platinum-sensitive recurrence maintenance (PSR-M), and treatment for ovarian cancer were evaluated. Survival outcomes and the factors influencing progression-free survival (PFS) were estimated. Results: The 93 patients received Niraparib as 1L-M, 31 as PSR-M and 18 as salvage. BRCA status was wild type or unknown in 87.3% of patients. With a median follow-up time of 8.7 months, the median PFS (mPFS) for 1L-M has not yet been reached, and the mPFS for PSR-M and salvage therapy was 10.5 and 5.7 months, respectively. Responses to last chemotherapy and cancer antigen 125 value before taking niraparib were 2 important factors affecting PFS among 1L and PSR patients. The 12.7% (18/142) of patients experienced grade ≥3 hematologic adverse events and 23.2% experienced dose adjustment. It was noteworthy that when the interval of chemotherapy and niraparib <21 days, the incidence of grade ≥3 adverse events increased significantly (p=0.0355). Conclusion Generally, niraparib was effective and well tolerated, which was consistent with the results of prospective trials. However, in real world, it was more inclined to use niraparib in late-line treatment without genetic testing.

Objective: To investigate the prognostic value of pretreatment albumin to globulin ratio(AGR)in prostate cancer(Pca)patients treated with maximal androgen blockade(MAB). Methods: Clinical and pathological data of 210 Pca patients who underwent MAB as first-line therapy between January 2013 and June 2018 were retrospectively analyzed.The ages of patients in our cohort ranged from 61 to 90 years, with a mean of(77.0±6.5)years.According to the cut-off point for AGR calculated by the receiver-operating curve analysis, patients were categorized into two groups: the high-AGR group and the low-AGR group.Clinical and pathological features were compared between the groups.Independent factors affecting prognosis were analyzed by using univariate and multivariate analysis. Results: The median follow-up duration was 44.0 months.Of the 210 patients, 99 cases had castration resistance, 100 patients(47.6%)had disease progression and 67 patients(31.8%)died.The cut-off point for AGR calculated by the receiver-operating curve analysis was 1.56.There were 103 cases in the low-AGR group(AGR<1.56)and 107 cases in the high-AGR group(AGR≥1.56). Univariate analysis revealed that the progression-free survival(PFS), cancer-specific survival(CSS)and overall survival(OS)were lower in the low-AGR group than in the high-AGR group[1.773(1.298~2.442), 1.948(1.220~3.213), 1.965(1.217~2.996), all P<0.05]. Multivariate Cox regression analysis showed that Gleason score, regional lymph nodes and bone metastases and AGR were independent prognostic factors for PFS(P=0.007, 0.040 and 0.022, P=0.031), CSS(P=0.003, 0.035 and 0.041, P=0.009)and OS(P=0.003, 0.026 and 0.023, P=0.002). Conclusions Pretreatment AGR<1.56 is an independent predictor for poor prognosis in Pca patients treated with MAB.

Objective To observe the metabolomic changes of amniotic fluid in control group and administration group,and to explore the toxicity of aqueous extract of rhubarb on reproduction and embryonic development of pregnant rats.Methods Pregnant rats in teratogenic sensitive period were given rhubarb aqueous extract by gavage for 10 days.The toxicity of rhubarb to maternal rats and the abnormal conditions of dead fetus and absorbed fetus were observed.The amniotic fluid samples were detected by liquid chromatography-mass spectrometry(LC-MS),the amniotic fluid metabolic profiles were compared by principal component analysis(PCA)and partial least squares(OPLS-DA),and the differential lipids were analyzed by metaboanalyst 5.0.Results Rhubarb administration in the teratogenic sensitive period can significantly reduce the number of live fetuses,and lead to adverse phenomena such as absorption of fetuses and premature death of fetuses.The preliminary results of lipomics showed that rhubarb could cause the metabolic disorder of amniotic fluid in pregnant rats,and there were metabolic abnormalities in lipids in amniotic fluid such as PI,PC and LPC.Conclusion Under the equivalent dose of the maximum dose recommended by the clinic,the aqueous extract of rhubarb has certain reproductive and embryonic toxicity to rats;Rhubarb may affect the normal development of rat embryos by causing the disorder of lipid metabolism in amniotic fluid.

【Objective】 To investigate the molecular mechanism of long non-coding RNA (lncRNA) TDRG1 in facilitating the malignant progression and poor prognosis of patients with cervical cancer. 【Methods】 Cervical cancer cell lines and normal cervical cell Ect1/E6E7 were collected. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression of TDRG1. Cervical cancer cell lines were transfected with TDRG1-siRNA, and the proliferation of cancer cells was detected by CCK-8 method and cell plate cloning experiment. The invasion and migration of cancer cells were measured by Transwell experiment. The apoptosis of cancer cells was examined by flow cytometry, and the expressions of relevant proteins were tested by Western blot. 【Results】 Compared with Ect1/E6E7, cervical cancer cell lines showed relatively increased expression of TDRG1. Downregulation of TDRG1 expression inhibited the proliferation and colony formation (162±21 vs. 411±33, P<0.05), as well as the invasion and migration (invasion: 86±13 vs. 315±38, P<0.01; migration: 177±22 vs. 406±41, P<0.01) of Hela cells. Meanwhile, the apoptosis of Hela cells increased [(28±1.5)% vs. (16±1.2)%, P<0.05] and the expression of Bcl-2 protein reduced. In addition, TDRG1 knockdown also decreased the activity of autophagy in Hela cells. 【Conclusion】 TDRG1 facilitates the malignant biological progression of cervical cancer by inhibiting the apoptosis and providing a protective autophagy in cervical cells.
