Amorphous solid dispersion (ASD) is one of the most effective formulation approaches to enhance the water solubility and oral bioavailability of poorly water-soluble drugs. However, maintenance of physical stability of amorphous drug is one of the main challenges in the development of ASD. Crystallization is a process of nucleation and crystal growth. The nucleation is the key factor that influences the physical stability of the ASD. However, a theoretical framework to describe the way to inhibit the nucleation of amorphous drug is not yet available. We reviewed the methods and theories of nucleation for amorphous drug. Meanwhile, we also summarized the research progress on the mechanism of additives influence on nucleation and environmental factors on nucleation. This review aims to enhance the better understanding mechanism of nucleation of amorphous drug and controlling over the crystal nucleation during the ASD formulation development.

Aim To investigate the mechanism of RhoA/ROCK signaling pathway in abnormal aortic contractility in type 2 diabetes (T2DM) mice. Methods The experiment was divided into two groups, the control group (db/m mice) and the model group (db/db mice). Changes of the response to different methods were measured in aorta rings using a Multi Myograph System. At the same time, the protein expression changes of aortic smooth muscle contraction signaling pathway in mice were determined by Western method. Results Compared with the control group, the blood glucose and body weight levels of the mice in the T2DM group significantly increased, and the cardiac function was abnormal (P <0. 01). The contractile response of the aorta of the diabetic mice induced by the contractile agents Phe, 5-HT and CaCl

Methods C57BL/6J mice were randomly assigned to the control group and the hypertension group ( treated with continuous administration of angiotensin for four weeks ). Masson staining was used to observe the fibrosis of mouse atrial tissue, while dot blot assay and Western blot were used to detect the levels of m6A, METTL3, and Cavi1 2 in the atrial tissue. A high hydrostatic pressure model was constructed using the HL-1 cell line cultured in vitro, and METTL3 was intervened to observe changes in m6A expression levels, METTL3 and Cavi1 2 levels in cells,and action potential duration ( APD ) and L-type calcium current ( I

Objective: To understand the current situation and influencing factors of online psychological help seeking behavior among college students in Guangxi, China, so as to provide a scientific basis for improving the mental health of college students. Methods: From March to June 2022, a convenient sampling method was employed to select 2 239 university students from eight universities in Guangxi. The survey included the College Student Online Psychological Help Behavior Questionnaire, General Help Seeking Questionnaire (GHSQ), Attitudes Toward Seeking Professional Psychological Help Scale short Form (ATSPPH-SF), and the 10 item Kessler Psychological Distress Scale (Kessler10) to statistically analyze online psychological help seeking behavior and associated influencing factors. Results: The score of online psychological help seeking behavior among college students was ( 13.96± 5.20), and the scores of the three dimensions were as follows: online psychological self-help behavior (7.13± 2.95 ), online non-professional psychological help seeking behavior (4.28±2.19), online professional psychological help seeking behavior (2.54± 1.29 ). The factors influencing online psychological help seeking behavior were ranked as follows: mental health ( β = 0.32), CHSQ ( β =0.21), gender ( β =-0.09), ATSPPH-SF ( β =0.09) and registered residence ( β =0.08) ( P <0.05). Conclusion The online psychological help seeking behavior of college students in Guangxi is influenced by factors such as mental health. Seeking psychological help online has become a new form of support aimed at meeting the psychological health needs of college students, and constitutes an important supplement to offline psychological assistance. While there are similarities and differences between both modes, universities should pay attention to them.

Objective:To study the efficacy of laparoscopic limited anatomical hepatectomy (LLAH) for hepatocellular carcinoma (HCC) within the right anterior section.Methods:The clinical data of 144 patients with HCC confined in the right anterior section undergoing hepatectomy at the First Affiliated Hospital of Army Medical University from January 2015 to December 2022 were retrospectively analyzed, including 122 males and 22 females, aged (54.5±9.7) years. Patients were divided into LLAH ( n=27), laparoscopic anatomical hepatectomy (LAH, n=69), and laparoscopic non-anatomical hepatectomy (LNAH, n=48). Propensity score matching was used to compare the operative time, postoperative hospital stay, postoperative complications, serum total bilirubin and albumin, and the prognostic indicators such as tumor-free survival (DFS) rate and cumulative survival rate between the groups. Results:After propensity score matching, there were 26 cases each in LLAH and LNAH group. There was no significant difference in operative time, intraoperative blood loss and postoperative hospital stay between LLAH group and LNAH group (all P<0.05). The total bilirubin and albumin in LLAH on the third day after operation were [ M( Q1, Q3)] 24.1(20.9, 29.1) μmol/L and (35.8±2.9) g/L, better than those in LNAH group 39.3(33.2, 57.0) μmol/L and (33.9±2.5) g/L, respectively. The 1- and 3-year DFS rates in LLAH group were 92.3% and 57.7%, higher than those in LNAH group (80.8% and 19.2%) (all P<0.05). After propensity score matching, there were 25 patients each in LLAH and LAH group. The operative time, postoperative hospital stay and postoperative complications of LLAH group were lower than those of LAH group, and the liver function parameters of LLAH group was also better than those of LAH group (all P<0.05). There was no significant difference in DSF rate between the two groups LLAH group and LAH group ( χ2=0.10, P=0.800). Conclusions:The perioperative outcome of LLAH for HCC within the right anterior section are similar to that of LNAH and better than that of LAH. The DFS of LLAH were better than that of LNAH and similar to that of LAH.
