Objective: To investigate the application of antigen avoidance pattern for compatible platelets matching. Methods: Samples from two patients with immune-mediated platelet transfusion refractoriness were screened for platelet antibodies using solid-phase red blood cell adhesion assay (SPRCA). The genotypes of HLA-A, -B loci were determined via ploymerase chain reaction sequence. The specificity of HLA class I antibodies was detected using Luminex technology. Results: Platelet antibody screening via SPRCA yielded positive results in both samples. Antibody specificity testing showed the presence of antibodies against HLA-B65, A80, B13, as well as antibodies against HLA-A11, B52, A24 respectively, with both patients exhibiting 80 kinds of positive antibodies. The antibody avoidance pattern successfully selected compatible platelets for transfusion. The bleeding symptoms of two patients were improved after compatible platelets transfusion. Conclusion: For blood stations with limited platelet gene bank resources, antibody avoidance pattern for compatible platelets matching represents an effective strategy for immune-mediated platelet transfusion refractoriness.

Objective To investigate the status of occult hepatitis B virus infection(OBI)among blood donors in Quzhou,Zhejiang,and to analyze the mutation of S region in blood donors with anti-HBc+alone and non anti-HBc+alone.Methods The OBI samples were screened by ELISA and NAT;the HBV DNA was amplified and sequenced;20 anti-HBc+alone and 25 not anti-HBc+alone samples were obtained.Results The detection rate of OBI in Quzhou was 0.10%(155/161 045),and the positive rate of anti-HBc was 74.19%(115/155).The detection rate of OBI increased with the age of blood donors(P＜0.05),but was not related to gender.The positive rate of anti-HBc+alone was 22.58%(35/155),and that of not anti-HBc alone was 51.61%(80/155).Among the 45 OBI sequencing samples,the proportion of B and C geno-type was73.33%(33/45)and 20.00%(9/45),respectively.The mutation sites of blood donors in the anti-HBc+alone group were more than those in the not anti-HBc+alone group,and the mutation rates of S114T and V168A on MHR were significantly different(P＜0.05).Conclusion The genotype of OBI infection in Quzhou is mainly type B.The mutation sites of blood donors with anti-HBc+alone are higher than those with not anti-HBc+alone,which may be more suitable as one of the OBI screening indicators.

Objective:To investigate the efficacy, safety and recurrence rate of oral atenolol in the treatment of infantile hemangioma, so as to provide evidence-based medicine basis and reference for clinic.Methods:Search on the following public databases from January 1, 2008 to June 13, 2022: Web of Science, PubMed, Cochrane Library, Embase, U. S. National Library of Medicine Clinical Trials Registry Platform; China National Knowledge Infrastructure(CNKI), Chinese Biomedical Literature Service System(SinoMed), Chinese Science and Technology Journal Database and Wanfang Data. According to inclusion and exclusion criteria, studies on oral atenolol for the treatment of infantile hemangioma were selected. The outcome indicators were efficiency (complete response rate), incidence of adverse effects and recurrence rate. The single-arm meta-analysis was performed using R software version 4.1.2. Egger’s test was employed and funnel plots were drawn to assess publication bias in the literature.Results:A total of 14 studies were included, comprising 5 randomized controlled trials, 5 single-arm studies, 3 non-randomized controlled trials, and 1 case-control study. The oral administration of atenolol for the treatment of infantile hemangiomas resulted in an efficacy rate (complete remission rate) of 62% (95% CI 52%~71%). The incidence rate of adverse reactions related to the digestive system was 18% (95% CI 7%~30%), while that related to β2 receptor blockade was 4% (95% CI 2%~6%), central nervous system-related adverse reactions occurred at a rate of 10% (95% CI 5%~16%), the recurrence rate was 5% (95% CI 2%~9%). Egger’s test indicated that there was no significant publication bias in the efficacy rate, central nervous system-related adverse reaction rate, and gastrointestinal-related adverse reaction rate of oral atenolol treatment for infantile hemangiomas ( P>0.05). The sensitivity analysis for the efficacy rate, adverse reaction rate, and recurrence rate of oral atenolol treatment for infantile hemangiomas suggested that the result were stable and reliable. Conclusion:Oral administration of atenolol for the treatment of infantile hemangiomas demonstrates significant efficacy, fewer adverse reactions, and a low recurrence rate, making it a promising candidate as a reasonable alternative to oral propranolol for treating infantile hemangiomas.

Acute pancreatitis (AP) is a severe disease with an increasing incidence rate in clinical practice. Although most patients have mild pancreatitis, the fatality rate of severe pancreatitis remains at a relatively high level, and therefore, early-stage, simple, and accurate clinical scoring systems are urgently needed to determine the severity of AP, so as to facilitate effective disease management and symptomatic treatment and reduce the fatality rate of patients. At present, a large number of studies have demonstrated that the scoring systems such as Ranson score, APACHE Ⅱ score, BISAP score, CTSI score, and some serological markers have been used to evaluate the severity and prognosis of AP, but all of them have certain limitations. This article reviews the research advances in the existing scoring systems, single serological markers, and related modified scoring systems in recent years. Through a literature review, it is concluded that there is no a single scoring system or a single indicator that can cover the whole process of AP diagnosis and treatment and accurately judge the severity of AP, and therefore, it is necessary to develop a new scoring system or combine various indicators for comprehensive evaluation.

Objective:This study aims to investigate the prevalence and distribution characteristics of mental disorders among people aged 18 and above in Shandong Province.Methods:In 2015, an epidemiological survey was carried out to investigate the patterns of mental disorders in 49 counties of Shandong Province. A total of 28 000 individuals aged 18 years or older were selected using the multistage stratified cluster sampling method. All these participants were classified as at a high or low risk of mental disorders according to the assessment results of the revised version of the General Health Questionnaire (GHQ). The diagnosis of mental disorders was confirmed using the Structured Clinical Interview for Diagnostic and Statistical Manual, Forth edition (DSM-Ⅳ) axis I or MMSE. All participants at high risk of mental disorders were evaluated using DSM-Ⅳ or MMSE to confirm the psychiatric diagnoses, while 10% of participants at low risk of mental disorders were randomly selected to be evaluated. The prevalence and its 95% confidence interval of mental disorders were adjusted according to study design and sociodemographic characteristics of the sample. The between-group differences of prevalence were compared using chi-square tests or Fisher′s exact tests as appropriately.Results:A total of 27 489 individuals completed survey. The adjusted prevalence of any mental disorder was 17.46% (95 %CI 17.02%-17.89%). The five most prevalent mental disorder spectrums were substance use disorders (5.29%), mood disorders (4.47%), anxiety disorders (4.46%), intellectual and mental disorders due to physical or substance (1.91%), and psychotic disorders (1.12%). The most common mental disorders were alcohol use disorder (5.27%) and major depressive disorder (2.14%). The prevalence of mental disorders in men was higher than that in women (23.37% vs. 13.89%; χ 2=408.91, P<0.01). There was no significant difference in the prevalence of mental disorders between rural residents and urban residents (17.69% vs. 17.20%; χ2=1.05, P=0.305). Of participants with mental disorders, 26.12% (1 047/4 008) had moderate to severe functional impairment and 10.98% (428/3 898) have sought professional help. Conclusion:The prevalence of mental disorders among people aged 18 and above in Shandong Province is basically consistent with the results of similar domestic studies. The prevalence of mental disorder was higher in men than in women and was not differ in participants living in urban and rural areas. Alcohol use disorder, major depressive disorder, non-specific anxiety disorder and non-specific depressive disorder are most common mental disorders.

Objective:To explore efficacy and safety of endovascular therapy combined with hyperbaric oxygen (HBO) intervention in acute anterior circulation macrovascular occlusion stroke.Methods:A total of 150 patients with acute anterior circulation macrovascular occlusive stroke admitted in No.902 Hospital of the CPLA Joint Logistic Support Force were selected and randomly divided into endovascular treatment group and combined treatment group (endovascular+ HBO). Endovascular therapy was adopted in the treatment of all patients. Modified thrombolytic flow grading (mTICI) was used to evaluate vascular recanalization after operation, and the incidences of complications of hemorrhage transformation and vascular re-occlusion were recorded. National institutes of health stroke scale (NIHSS) was used to evaluate the neurological functions on admission, at 24 hours after the operation, and one course after HBO therapy. The prognosis was evaluated by observing the changes of blood homocysteine (HCY) and high-sensitivity C-reactive protein (hs-CRP) levels before and after treatment. The patients had been followed up by the modified Rankin Scale (mRS) for 90 days. At the same time, 75 patients with acute anterior circulation macrovascular occlusive stroke without taking endovascular treatment were selected as the control group.Results:Among 150 patients, 126 cases had a grade of mTICI≥2b, while 24 cases had a grade of mTICI<2b. Postoperative vascular re-occlusion occurred in 3 cases, and symptomatic intracranial hematoma occurred in 6 cases. The NIHSS score at 24 hours after the operation was significantly lower than that on admission, and the NIHSS score was further improved after HBO treatment. Ninety days after the operation, mRS showed 98 cases of good prognoses, while 52 cases of poor prognoses. The levels of HCY and hs-CRP were significantly lower than those before the treatment.Conclusion:Endovascular therapy for acute anterior circulation macrovascular occlusive stroke is safe and effective. Postoperative HBO therapy can significantly improve the prognosis and the quality of life of patients.
