Relationship between social support and psychological resilience and post traumatic stress disorder in college students / 中国学校卫生

Objective@#To investigate the characteristics of post traumatic stress disorder (PTSD) in college students during the outbreak of COVID-19, and to explore the mediating role of psychological resilience between social support and PTSD.@*Methods@#By using direct selection method, 572 college students in Anhui and Shanghai were selected and administered with General Characteristics Questionnaire, the PTSD Checklist Civilian Version(PCL-C), Psychological Resilience Scale(PRS) and Social Support Rating Scale(SSRS).@*Results@#Among the participants, 25.0% had moderate PTSD symptoms, 11.7% had obvious PTSD symptoms, and the positive rate of PTSD was 36.7%. The prevalence of PTSD in college students was higher in males than in females ( χ 2= 4.31， P <0.05). The junior students were higher than other students ( χ 2=16.81， P <0.01). The scores of social support, psychological resilience and PTSD were (33.79±4.83), (92.17±13.39) and (35.50±11.39), respectively. The correlations of all variables were statistically significant( r =-0.49-0.76， P <0.05); The mediation test showed that social support could not only negatively predict PTSD directly(direct effect was -0.35), but also indirectly affect PTSD through psychological resilience(indirect effect was -0.32).@*Conclusion@#More than one third of college students have PTSD symptoms, and psychological resilience plays a partial mediating role in the relationship between social support and PTSD,social support can both directly and negatively predict PTSD and indirectly affect PTSD by increasing an individual s psychological resilience.

Meta-analysis of correlation between serum albumin content and prognosis in patients with severe traumatic brain injury / 中华创伤杂志

Objective:To systematically evaluate the effect of serum albumin content on the prognosis of patients with severe traumatic brain injury (TBI).Methods:PubMed, Embase, Cohrane Library, China National Knowledge Infrastructure (CNKI), China Biomedical Literature Database (CBM), China Journals Full-text Database (CJFD), VIP database and Wanfang Database were used for retrieval from inception to November 10, 2020. Through retrieving Chinese and English literatures, relevant studies on serum albumin content in different types of TBI patients and in severe TBI patients with different prognostic results were included. The difference of serum albumin content in patinets with severe TBI with healthy people and patients with mild illness TBI, and the difference in serum albumin content between patients with good and poor prognosis of severe TBI were observed. At the same time, the differences in serum albumin content between subgroups were evaluated by subgroup analysis of the authors' country, literature quality and severity of the control group according to characteristics that might cause heterogeneity.Results:A total of 9 articles were included in this study, including 1, 438 study subjects. The serum albumin content in patients with severe TBI was significantly lower than that in healthy individuals and patients with mild TBI ( WMD=-6.42, 95% CI -9.95--2.80, Z=3.82, P<0.01). Subgroup analysis showed that serum albumin content in patients with severe TBI was significantly lower than that in healthy people ( WMD=-8.77, 95% CI-10.28--7.25, Z=11.37, P<0.01). Serum albumin content in patients with severe TBI was significantly lower than that in patients with mild TBI ( WMD=-4.07, 95% CI -9.53 -1.39, Z=1.46, P<0.05), suggesting that mild TBI patients are the main source of heterogeneity. The serum albumin content in patients with poor prognosis of severe TBI was significantly lower than that in patients with good prognosis of severe TBI ( WMD=-4.48, 95% CI-7.39--1.58, Z=3.02, P<0.01). Conclusion:Serum albumin content in patients with severe TBI is significantly lower than that in healthy individuals as well as in patients with mild TBI, and low albumin content indicates a poor prognosis in patients with severe TBI.

Voice analysis of early glottic carcinoma treated by carbon dioxide laser / 临床耳鼻咽喉头颈外科杂志

Objective@#The aim of this study is to investigate the effect of CO2 laser cordectomy on the voice of early glottic carcinoma. @*Method@#A retrospective analysis of 40 patients who underwent CO2 laser treatment early glottis preoperative clinical data of postoperative laryngeal cancer patients, patients with postoperative recurrence rate, survival rate, and the postoperative complications of patients with preoperative and postoperative laryngoscopy, voice disorders index（voice handicap index, VHI） simplified Chinese version（VHI 13） rating scale, affecting the stability sound quality postoperatively in patients with laryngeal cancer were discussed. @*Result@#All patients underwent voice reexamination 8-97 months after surgery, and the survival rate was 100%, no local recurrence and no obvious postoperative complications. Compared with the healthy control group, there were statistically significant differences in the four indicators F0（fundamental frequency）, Jitter（fundamental frequency perturbation）, Shimmer（amplitude perturbation） and MPT（maximum pronunciation time）, suggesting that CO2 laser surgery resulted in significant changes in acoustic parameters. Jitter and Shimmer indexes in the pre involved combined group were statistically significant different from those in the non involved combined group, suggesting that the sound quality of the pre involved combined group was worse in the postoperative stability period. The VHI score indicated that most patients with early glottic cancer were in severe voice disorder before operation and most were in moderate voice disorder after operation. Compared with the healthy control group, the VHI score and total score of the healthy control group were lower in terms of physiology, psychology and emotion. Compared with the healthy control group, the VHI score and physiology of the early glottic laryngeal cancer patients were lower in the early glottic laryngeal cancer patients before and after surgery, and they were statistically significant. @*Conclusion@#CO2 laser surgery for early glottic cancer, the overall survival rate of patients, low recurrence rate, fewer complications, CO2 laser surgery led to significant changes in acoustic parameters, postoperative sound quality and whether the involvement of pre-associated factors; The total score of VHI and physiological score of early glottic carcinoma patients after CO2 laser operation were better than those before operation.

Research progress in the relationship between vitamin and inflammatory bowel disease / 中国综合临床

Objective Inflammatory bowel disease(IBD)is an unexplained chronic and recurrent inflammatory disease of the intestine,including ulcerative colitis(UC)and Crohn′s disease(CD).At present, the etiology and pathogenesis of IBD are still not clear,and it is believed to be related to the environment, inheritance,infection,immunity and other factors.With the increase of people′s living standard and the economic and social development,the incidence of IBD in China is a rising trend year by year,the impact of diet on the incidence of IBD and the influence of nutritional support on the prognosis of IBD have attracted more and more attention.Vitamin is one of the seven nutrients and is an indispensable part of the health of the body.In recent years,some vitamins have been proved to be related with the occurrence and development of IBD.
