In multivariate analysis, DSAs were the only factor highly associated with graft failure (P ‫؍‬ .0001; odds ratio ‫؍‬ 21.3). Anti-HLA allosensitization was higher overall in women than in men (30.8% vs 12.1%; P < .0001) and higher in women with 1 (P ‫؍‬ .008) and 2 or more pregnancies (P ‫؍‬ .0003) than in men. We conclude that the presence of anti-DPB1 DSAs is associated with graft failure in MUD hematopoietic stem cell transplantation. (Blood. 2011;118(22):5957-5964)

ObjectiveIn patients with chronic hepatitis B virus (HBV) infection, it is not known whether altered serum iron markers are directly because of the infection or the associated liver injury. We determined the serum iron status of patients with chronic HBV infection, and investigated whether it is HBV infection or HBV-related liver injury that likely causes abnormal serum iron markers in chronic HBV infection.Materials and methodsFor a retrospective study, chronic HBV-infected patients (80 patients with cirrhosis and 76 patients without cirrhosis) and 58 healthy controls were enrolled. Serum alanine transaminase levels were measured to ascertain liver damage. Indicators of iron status included serum iron, ferritin, and transferrin.ResultsCompared with noncirrhotic patients and healthy controls, the serum transferrin of cirrhotic patients was lower and the serum iron and ferritin values were higher (P<0.001, all). In cirrhotic patients, the serum iron and ferritin levels correlated positively with serum alanine transaminase levels and the transferrin levels were inversely related to both end-stage liver disease scores and iron levels (all P<0.01).ConclusionSerum iron markers tended to be aberrant in chronic HBV-infected patients with cirrhosis. The liver injury associated with HBV infection, but not chronic HBV infection directly, is likely the main cause for iron metabolism disorder.

The role of lower esophageal sphincter (LES) in laryngopharyngeal reflux is controversial. In this study, we used an animal model to investigate the association between LES dysfunction and reflux laryngitis. Twelve healthy New Zealand albino rabbits (2.5-3.5 kg) were utilized in this study. The animals were divided into two groups. Eight rabbits underwent total cardiomyectomy to induce reflux, and the remaining four rabbits underwent a control sham operation. A laryngoscopy and a 24-hour intra-esophageal pH-metry were performed prior to surgery and again 2 and 8 weeks postsurgery. After the final laryngoscopy, all animals were sacrificed to obtain histological results. Total cardiomyectomy significantly increased the reflux index, the duration of the longest reflux episode and the total number of episodes that occurred in 24 h postsurgery. No significant difference was observed in the reflux finding score (RFS) between preoperative and 2-week postoperative rabbits (P = 0.11). But there was a statistically significant change in the RFS before and 8 weeks after the induction of reflux from 4.6 ± 0.9 to 8.3 ± 3.6 (P = 0.02). Submucous gland hyperplasia and inflammation were significantly increased in the reflux group compared to the control group. The results of this study suggest that chronic lower esophageal sphincter dysfunction is associated with reflux laryngitis in rabbits.

Background: A meta-analysis was conducted on the correlation between intestinal flora and gestational diabetes mellitus (GDM) to provide a theoretical basis for the treatment of GDM.Methods: The PubMed, Embase, MEDLINE, Ovid, Springer, and Web of Science databases were searched from the establishment of the databases to December 31, 2020, to retrieve randomized control trials (RCTs) involving GDM patients. The Cochrane Handbook for Systematic Reviews of Intervention 5.0.2 was used to assess the bias risk of the included articles, and Rev Man 5.3 was used for the meta-analysis.Results: A total of 7 studies were included in the meta-analysis, comprising 665 study participants.The meta-analysis results showed that the GDM patients in the experimental group had a lower level of Bifidobacterium [MD (mean difference) =-2.49; 95% confidence interval (CI) -3.54 to -1.45; Z=4.66;

Objectives: Women affected by rheumatoid arthritis (RA) have a higher risk of endometriosis, an estrogen-dependent, chronic inflammatory disease. Though acupuncture has long been a safe and effective therapy for treating inflammatory conditions, it is unclear whether it could prevent the onset of endometriosis. This study aims to determine the effect of acupuncture on the subsequent risk of endometriosis in female RA patients.Methods: Between 1998 and 2010, female subjects with RA were recruited from a nationwide database (5,736 patients; age ≥20 years). Enrolled patients included 2,407 acupuncture users and 2,407 nonusers randomly selected using propensity scores. The occurrence of endometriosis was recorded through the end of 2012. Cox proportional hazards regression was used to estimate the adjusted hazard ratio (HR) associated with acupuncture use.Results: During the follow-up period, 35 acupuncture users and 94 non-users developed endometriosis, with incidence rates of 2.36 and 4.91 per 1,000 person-years, respectively. Acupuncture use was associated with a 55% lower endometriosis risk (adjusted HR, 0.45; 95% confidence interval, 0.31–0.65). Those who received high intensity acupuncture (≥15 packages) had the greatest benefit.Conclusions: Findings suggest that adding acupuncture to conventional therapy may decrease the subsequent endometriosis risk in female RA patients. Prospective randomized trials are recommended to further clarify whether the association revealed in this study supports a causal link.

Background: Gynecological laparoscopic surgery is the main method to treat gynecological diseases, but postoperative gastrointestinal reactions are more common in patients. Auricular therapy, as a characteristic therapy of Traditional Chinese Medicine, can improve gastrointestinal symptoms such as nausea and vomiting by stimulating the conduction of acupoints through the nervous system on internal organs, but there are studies questioning the efficacy of auricular therapy. Therefore, the purpose of this study is to prove the efficacy and safety of auricular therapy in promoting gastrointestinal function recovery after gynecological laparoscopic surgery, and to provide reference value for future clinical practice. Methods: To search English databases (PubMed, Excerpta Medical Database [Embase], Web of Science, the Cochrane Library) and Chinese databases (Chinese National Knowledge Internet [CNKI], WanFang, Viper, Chinese Biomedical Literature Database) by computer, and conduct a randomized controlled trial on the effect of aural point therapy on gastrointestinal function recovery of patients after gynecological laparoscopic surgery from the establishment of the database to October 2020. Two researchers independently evaluate the quality of the included studies and extract the data, and meta-analysis of the included literature is carried out using RevMan5.3 software. Results: In this study, the efficacy and safety of auricular therapy in the recovery of gastrointestinal function after gynecological laparoscopic surgery are evaluated from the aspects of first anal exhaust time, bowel sound recovery time, and incidence of gastrointestinal complications. Conclusion: This study will provide reliable evidence-based evidence for auricular therapy in the treatment of gastrointestinal function after gynecologic laparoscopic surgery.
