In the past decade, the population of international students enrolling in Chinese colleges and universities has been increasing rapidly, with the students in Asia taking the most portions. Chinese higher education institutions are facing great challenges in their course of internationalization. Therefore the studies on the intercultural adaptation of international students in Chinese higher education institutions have received extensive attention. The present research was conducted to investigate the intercultural adaptation of the Pakistani students at the Chinese universities in forms of a questionnaire and interviews. Colleen Ward's cultural adjustment process model is used as the analytical lens to explore the life and study experiences of the Pakistani students from their perspectives and to understand the challenges they experienced during their intercultural communication. The students' personal reports will collectively provide some valuable information for Chinese universities to understand cultural differences that international students is bringing to Chinese campuses and to help them succeed in a totally different academic setting.

Objectives: This meta-analysis assessed the treatment effectiveness of acupuncture in patients with vascular dementia., Methods: The PubMed, Embase, Cochrane library, and China National Knowledge Infrastructure were searched to identify eligible randomized controlled trials (RCTs). The odds ratios (ORs) and weighted mean differences (WMDs) with 95 % confidence intervals (CIs) were used to assess the pooled effect estimates using a random-effects model for categorical and continuous outcomes, respectively., Results: Thirty-four RCTs (2672 patients) were selected for the final meta-analysis. The use of acupuncture showed association with an increased incidence of effective rate (OR: 3.28; 95 % CI: 2.54-4.24; P < 0.001). The pooled WMDs revealed that acupuncture was significantly associated with an improvement in the Hasegawa dementia scale (HDS) (WMD: 4.31; 95 % CI: 3.15-5.47; P < 0.001), and Mini-Mental State Examination scores (MMSE) (WMD: 3.07; 95 % CI: 2.40-3.74; P < 0.001). However, the use of acupuncture showed no association with the level of Activities of daily living (ADL) (WMD: 1.93; 95 % CI: - 2.53 to 6.38; P = 0.397). Finally, acupuncture was associated with lower levels of Scale for the differentiation of syndromes of vascular dementia (SDSVD) (WMD: - 2.15; 95 % CI: - 4.14 to - 0.16; P = 0.034), and National Institutes of Health stroke scale (NIHSS) (WMD: - 3.90; 95 % CI: - 4.87 to - 2.94; P < 0.001)., Conclusions: Acupuncture is probably helpful in vascular stroke, but strong supportive data are not yet available. Acupuncture should be used cautiously, owing to the analysis of this study based on low to moderate evidence. Further high-quality, large-scale RCTs should be conducted., (Copyright © 2022.

Background: To identify novel clinical phenotypic signatures of congenital nephrogenic diabetes insipidus (CNDI)., Methods: A Chinese family with CNDI was recruited for participation in this study. The proband and one of his uncles suffered from polydipsia and polyuria since infancy. The results of clinical testing indicated the diagnosis of CNDI. 10 family members had similar symptoms but did not seek medical advice. Genetic testing of mutations in the coding region of the aquaporin 2 ( AQP2 ) gene and the arginine vasopressin receptor 2 ( AVPR2 ) gene were carried out in 11 family members. Somatic DNA from 5 female family members was used to test for methylation of polymorphic CAG repeats in the human androgen receptor (AR) gene, as an index for X-chromosome inactivation pattern (XCIP)., Results: AQP2 gene mutations were not found in any family members, but a novel missense mutation (814th base A>G) in exon 2 of the AVPR2 gene was identified in 10 individuals. This mutation leads to a Met 272 Val (GAT-GGT) amino acid substitution. Skewed X-chromosome inactivation patterns of the normal X allele were observed in 4 females with the AVPR2 gene mutation and symptoms of diabetes insipidus, but not in an asymptomatic female with the AVPR2 gene mutation., Conclusions: Met 272 Val mutation of the AVPR2 gene was identified as a novel genetic risk factor for CDNI. The clinical NDI phenotype of female carriers with heterozygous AVPR2 mutation may be caused by X-chromosome inactivation induced by dominant methylation of the normal allele of AVPR2 gene., Competing Interests: The authors declare that they have no conflict of interest., (Copyright © 2022 Li Zang et al.)
