BACKGROUND Prior studies have noted great variability in the plasma levels of risperidone(RIS).Plasma concentrations of RIS and its active moiety are highly variable and depend on absorption,metabolism,and other predictors of metabolic dysregulation;however,these factors are poorly understood and the association between metabolic change and change in psychopathology is *** To ascertain the characteristics of chronic schizophrenic patients treated with RIS,and to assess their relationship with plasma RIS *** This was a descriptive cross-sectional study of 50 patients with a diagnosis of schizophrenic psychosis treated with RIS in a psychiatric *** plasma concentrations of RIS and its metabolite 9-hydroxyrisperidone were determined by high performance liquid *** patients’demographic and clinical characteristics,and psychopathologies were assessed,and the associations between clinical variables and plasma levels of RIS were *** Male patients received higher doses of RIS than female ones,but plasma concentrations of RIS and risperidone+9-hydroxyrisperidone(active moiety)were higher in female *** and the mean scores of the general psychopathology subscale of the Positive and Negative Syndrome Scale(PANSS)were significantly positively correlated with plasma concentrations of risperidone+9-hydroxyrisperidone adjusted for weight and dose in all 50 *** male subjects,we found a statistically significant positive correlation between the concentrations of risperidone+9-hydroxyrisperidone in plasma/(dose×kg)and age,mean PANSS negative subscale scores,mean PANSS general psychopathology subscale scores,and mean PANSS total *** Long-term use of RIS should be closely monitored in older patients and females to minimize the risk of high concentrations which could induce side effects.

BACKGROUND： Recent studies have shown that α2-adrenergic agonists can reduce postresuscitation myocardial injury. This study was undertaken to observe changes of hemodynamics, myocardial injury markers cTnT and cardiac morphology by establishing a cardiopulmonary resuscitation model with rabbits, and to detect whether a-methyl norepinephrine （α-MNE） can reduce the myocardial injury after CPR and improve cardiac ***： Eighteen health rabbits, weighing 2.5-3.5 kg, both male and female, were provided by the Lanzhou Institute of Veterinary Medicine. After setting up a rabbit model of cardiopulmonary resuscitation, 18 rabbits were randomly divided into three groups. The rabbits in group A as an operation-control group were subjected to anesthesia, endotracheal intubation, and surgery without induction of ventricular fibrillation. The rabbits in group B as an epinephrine group were administered with 30 μg/kg epinephrineduring CPR. The rabbits in group C as a MNE group were administered with 100 μg/kg a-MNE during CPR. The left ventricular end-diastolic pressure （LVEDP）, left ventricular pressure rise and fall rate （＋dp/dt） and serum concentrations of BNP were measured.

The increase of LVEDP was lower in group C than in group B （P〈0.05）, whereas peak±dp/dt was higher in group C than in group B （P〈0.05） at the same stage. Compared to group A, the cTnT of the remaining two groups increased, respectively （P〈0.01）, and peaked at 30 minutes, cTnT was less elevated in group C than in group B （P〈0.05） during the same period.

Viable but non-culturable （VBNC） bacteria after chlorination disinfection pose a considerable threat to the public health and environment. The current work aimed to uncover the stress adaptation mechanisms of VBNC S. Enteritidis to sodium hypochlorite. In this study， we investigated the morphology， gene expressions and proteomic profile in VBNC S. Enteritidis. It demonstrated that 109cells mL-1of bacteria could transition into the VBNC state after exposure to 50 mg L-1chlorine for 2.5 h. The VBNC state cells exhibited cellular membrane impairment， decreased size， and intracellular ATP depletion compared to the culturable cells. In the VBNC state cells， there was a significant increase in intracellular reactive oxygen species （ROS） levels and NAD+/NADH ratios. This observation suggested an imbalance in the intracellular redox status of the VBNC bacteria. Transcriptome and proteomic analysis revealed significant upregulation of the resistance-nodulation-division （RND） efflux systems （arcA， tolC， ramA）， oxidative stress response genes （soxR， trxA， grxB）， DNA repair genes （lexA， radA， mutH， mutL）， and virulence factor genes （sseA， sseL， eutS， and eutN）. Our findings indicated that it is important to formulate disinfection protocols that are specifically designed for food processing plants and healthcare facilities， focusing on implementing a more thorough disinfection method to effectively eradicate VBNC cells.

Developing new polymeric semiconductors with excellent device performance is essential for organic electronics. Herein, we synthesized two new thiazoloisoindigo(Tz II)-based polymers, namely, P(Tz II-d Th-d Th) and P(Tz II-d Th-d Tz), by copolymerizing thiophene-flanked Tz II with bithiophene and bithiazole, respectively. Owing to the more electron-deficient nature of bithiazole than bithiophene, P(Tz II-d Th-d Tz)possesses deeper LUMO/HOMO levels of-3.45/-5.47 e V than P(Tz II-d Th-d Th)(-3.34/-5.32 e V). The organic field-effect transistor(OFET) devices based on P(Tz II-d Th-d Th) exhibited p-type behaviors with an average hole mobility value as high as 1.43 cm^(2)·V^(-1)·s^(-1), while P(Tz II-d Th-d Tz)showed typical ambipolar characteristics with average hole and electron mobilities of 0.38 and 0.56 cm^(2)·V^(-1)·s^(-1). In addition, we compared the performances of both polymers with other Tz II-based polymers reported in our previous work, and showed that the charge carrier polarity can be manipulated by adjusting the number of the thiophene units between the acceptor unit. As the increase of the number of thiophene rings,charge carrier polarity shifts from electron-dominated ambipolar transport to hole-dominated ambipolar transport and then to unipolar hole transport in OFETs, which provides an effective molecular design strategy for further optimization of polymer OFET performance.

K-means聚类算法存在的主要不足之处之一在于需要用户指定聚类核数目,在一般应用场景下,用户无法给出合适的聚类核数目.另一方面,K-means聚类所具有的可并行化特点非常适合运用到云计算平台上以处理大规模数据样本的聚类任务.本文提出KBAC算法采用K-means算法作为预聚类过程并在云平台上进行实现和优化,能够自适应确定最佳聚类核数目并进行聚类.其核心思想是将样本空间聚类问题转换为图上社团发现问题.理论和实验证明,通过在云计算框架下实现K-means预聚类过程的并行化,KBAC算法能够高效地对大规模数据进行聚类,并获得高质量的聚类结果.
