This study was aimed to investigate the efficiency of 4 different culture media for in vitro culture and expanding adult human bone marrow mesenchymal stem cells (ahBM-MSCs) so as to establish a protocol of culturing and expanding hBM-MSCs and provide exprimental basis for hematopoietic blood stem cell transplantation combined with BM-MSCs. BM-MSCs were obtained from 16 fresh adult human bone marrow aspirate by gradient centrifugation with Ficoll Paque, then cultured in DMEM/F12 with 10% umbilical cord blood serum, 10% fetal calf serum (FCS), human blood serum, and MesenCult culture medium. The surface antigens of BM-MSCs were detected by flow cytometry. BM-MSCs were differentiated into osteoblasts and adipocytes under culture in the conditioned medium special for osteogenesis, and adipogenesis and the differentiated MSCs were identified by morphological observation, immunophenotype and immunohistochemical staining. The results showed that BM-MSCs could be isolated from adult human bone marrow and cultured by all culture media. The effect of umbilical cord blood serum on BM-MSC proliferation and their purity were similar to that of MesenCult culture medium, but better than that of FCS and human blood serum. The positive rate of CD29, CD73, CD105 on BM-MSCs cultured in umbilical cord serum and MesenCult medium was higher than that in FCS and adult human serum (p < 0.05), and the positive rate of CD31 was lower than that in FCS and adult human serum (p < 0.05). The positive rate of BM-MSCs differentiated into osteoblasts and adipocytes under culture in the conditioned medium for osteogenesis and adipogenesis with umbilical cord blood serum and MesenCult culture medium was also higher than that in FCS and adult human serum (p < 0.05). It is concluded that BM-MSCs can be obtained by all the four methods. DMEM/F12 with 10% umbilical cord blood serum and MesenCult culture medium are better than the others for the purification and differentiation potency of BM-MSCs in vitro. The medium with umbilical cord serum is valuable for clinical application in HSCT.

BACKGROUND This study aimed to analyze the risk factors of central nervous system (CNS) infection caused by reactivation of varicella zoster virus (VZV) and provide reference for the prevention and early diagnosis of VZV-associated CNS infection. MATERIAL AND METHODS A prospective study was conducted on 1030 patients with acute herpes zoster (HZ) admitted to our hospital from January 2021 to June 2023. According to clinical manifestations and auxiliary examinations, they were divided into HZ group of 990 patients and VZV-associated CNS infection group of 40 patients.

Background: Practice guidelines recommend patient management based on scientific evidence. Quality indicators gauge adherence to such recommendations and assess health care quality. They are usually defined as adverse event rates, which may not fully capture guideline adherence over time.

Background: Head and neck cancer (HNC) is amongst the 10 most common cancers worldwide and has a major effect on patients' quality of life. Given the complexity of this unique group of patients, a multidisciplinary team approach is preferable. Amongst the debilitating sequels of HNC and/or its treatment, swallowing, speech and voice impairments are prevalent and require the involvement of speech-language pathologists (SLPs).

Following the (revised) latent state-trait theory, the present study investigates the within-subject reliability, occasion specificity, common consistency, and construct validity of cognitive control measures in an intensive longitudinal design. These indices were calculated applying dynamic structural equation modeling while accounting for autoregressive effects and trait change. In two studies, participants completed two cognitive control tasks (Stroop and go/no-go) and answered questions about goal pursuit, self-control, executive functions, and situational aspects, multiple times per day.

With the advancement of precise hepatobiliary surgery concepts, the diagnostic and therapeutic approaches for hepatic echinococcosis have undergone significant transformations. However, whether these changes have correspondingly improved patient outcomes remains unclear. A retrospective analysis of these changes will provide crucial guidance for the prevention and treatment of hepatic echinococcosis.
