Atypical antipsychotics as first-line drugs have been used in patients with schizophrenia in China and abroad. However, its safety still needs to be evaluated in a large population, especially in Chinese patients.

The main objective of this study is to evaluate the safety and related factors of long-term atypical antipsychotic use in patients with schizophrenia in China. The secondary objective includes the long-term efficacy of atypical antipsychotics in these patients, as well as pharmacoeconomic evaluation, population pharmacokinetic studies and pharmacogenomics studies.

This study has an observational design. The atypical antipsychotics include quetiapine, olanzapine, risperidone, aripiprazole, ziprasidone, paliperidone, amisulpride, perospirone and clozapine. Visits occur at 0, 4, 8, 13, 26, 52, 78, 104, 130 and 156 weeks. The efficacy evaluations include symptoms, social function, recurrence rate and hospitalisation. The safety measures include physical examination, vital signs, abdominal circumfedy.
Patients with major depressive disorder (MDD) may have an abnormal peripheral body temperature rhythm, but its relationship with suicidal risk and the response to treatment with antidepressants remain unknown.

This study aimed to investigate the feature of peripheral body temperature in patients with MDD and its relationship with suicide risk before and after treatment with antidepressants.

This is a prospective case-control study. Patients diagnosed as MDD were enrolled into MDD group. Healthy subjects who matched in terms of gender, age and body mass index were enrolled into normal control (NC) group. The 24-hour peripheral body temperatures were monitored by
the next day after assessment. Patients with MDD were re-assessed after a 2-week treatment with antidepressants. All temperature data were fitted into cosine curves by
.

There were 41 patients with MDD, and 21 NC participants enrolled and completed the baseline assessments before the treatment. Patients with MDD were further divided into sts with MDD might have abnormal peripheral body temperature. The abnormal phase-delay of peripheral body temperature may indicate suicide risk in patients with MDD, depending on validation in large-scale cohorts.
This study investigated the impact of promoter methylation of flouropyrimidine (FP) metabolizing and cyclooxygenase 2 (COX2) genes on their mRNA expression and on the clinical outcome of colorectal cancer (CRC) patients.

Methylation specific-PCR and real time-PCR of thymidylate synthase (TS), thymidine phosphorylase (TP), dihydropyrimidine dehydrogenase (DPD) and COX2 were performed at baseline and after 3 and 6 months of FP therapy. Pairwise comparisons were conducted between the subgroups of CRC patients. The event free survival (EFS) and the hazard of progression were estimated by univariate and multivariate analyses.

At baseline CRC patients, both TS and TP were overexpressed, in spite of the unmethylation of TS and the full methylation of TP genes. Significant downexpression of DPD and COX2 were associated their promoter's methylation. At the end of FP therapy, TS, DPD and COX2 were overexpressed by 7.52, 2.88 and 3.45 folds, respectively, while TP was downexpressed by 0.54 fold. However, no change was observed in the methylation status of genes with FP therapy. Pairwise comparisons revealed significant difference in the expression and the methylation status of genes according to the clinicopathological characters of CRC patients either at baseline or after FP therapy. The overexpression of DPD and COX2 genes were indicators for a poor EFS of CRC patients. Also, the high level of COX2 expression was found to be significantly correlated with the hazard of progression (HR = 1.73, 95% CI = 1.02-3.03).

The promoter methylation of FP metabolizing and COX2 genes has significant impact on the expression and the treatment outcome of CRC patients.

First, the lack of site-specificity results in heterogeneous products and irreproducible processes. Second, potential modifications near the complementarity determining region (CDR) may reduce binding affinity and specificity. Conversely, site-specific methods produce well-defined and more homogenous antibody conjugates, ensuring developability and clinical applications. Moreover, several recent side-by-side comparisons of site-specific and stochastic methods have demonstrated that site-specific approaches are more likely to achieve their desired properties and functions, such as increased plasma stability, less variability in dose-dependent studies (particularly at low concentrations), enhanced binding efficiency, as well as increased tumor uptake. Herein we review several standard and practical site-specific bioconjugation methods for native antibodies, i.e., those without recombinant engineering. First, chemo-enzymatic techniques, namely transglutaminase (TGase)-mediated transamidation of a conserved glutamine residue and glycan remodeling of a conserved asparagine N-glycan (GlyCLICK), both in the Fc region. Second, chemical approaches such as selective reduction of disulfides (ThioBridge) and N-terminal amine modifications. Furthermore, we list site-specific antibody-drug conjugates (ADCs) in clinical trials along with the future perspectives of these site-specific methods.Oculodermal melanocytosis (ODM), though rare, is associated with a number of sight-threatening complications including glaucoma. The purpose of this Case Series study was to determine the ophthalmic features in patients diagnosed with ODM. Here, we describe five patients presented with ODM, with the most common ocular features identified being hyperpigmentation of the conjunctiva, sclera and heterochromia iridis. Others included hyperpigmentation of trabecular meshwork, glaucoma, cataract, retinal detachment and ocular hypertension in one patient. https://www.selleckchem.com/ As such, all patients with ODM should have a comprehensive ocular evaluation.
