BackgroundAs a high prevalence disorder, schizophrenia has caused significant burden to family and society due to the impairment of occupational and social function. Currently, the dominant vocational training model in China follows a paternalistic, clinician-led decision-making approach. Although it improves patients' social function to some extent, it undermines their autonomy and treatment adherence. Therefore, it is urgently necessary to explore a new intervention method to enhance treatment compliance and social function in patients. ObjectiveTo explore the impact of shared decision-making oriented vocational training on social function in hospitalized schizophrenia patients, so as to provide references for rehabilitation interventions. MethodsA total of 68 patients diagnosed with schizophrenia according to the International Classification of Diseases, tenth edition (ICD-10) criteria were consecutively enrolled from January to June 2024 at The Third People's Hospital of Wenjiang Distric, Chengdu. Participants were randomly allocated into the research group (n=34) and the control group (n=34) using a random number table method. Both groups received routine rehabilitation training, while the research group received shared decision-making oriented vocational training for 12 weeks, 2 times a week for 2 hours each time. Before and at the 4th and 12th week of intervention, two groups were evaluated by General Self-Efficacy Scale (GSES), Stigma Scale for Mental Illness (SSMI), Scale of Social function of Psychosis Inpatients (SSFPI) and Inpatient Psychiatric Rehabilitation Outcome Scale (IPROS). ResultsA total of 63 participants completed the study, with 30 cases in the research group and 33 cases in the control group. Repeated measures ANOVA revealed statistically significant time effects and interaction effects in both groups for GSES, SSMI, SSFPI and IPROS scores (F=20.451, 16.022; 26.193, 12.944; 23.957, 5.023; 11.776, 3.985, P<0.05 or 0.01), while no significant group effects were observed (F=0.188, 0.742, 1.878, 0.474, P>0.05). At the 12th week of intervention, there were statistically significant differences in GSES, SSMI, SSFPI and IPROS scores between the two groups. ConclusionShared decision-making oriented vocational training may help to improve social function in patients with schizophrenia. [Funded by 2023 Chengdu Medical Research Project (number, 2023468)]

Objective:To investigate the current status of multidrug-resistant bacteria (MDRO) wound infections in patients with autoimmune bullous diseases (AIBDs), and to analyze their risk factors.Methods:A retrospective study was conducted, and inpatients with AIBDs accompanied by wound infections were collected from Hospital of Dermatology, Chinese Academy of Medical Sciences from January 2020 to December 2022. A descriptive analysis was carried out to analyze the basic characteristics of these patients and pathogenic characteristics of MDRO. Univariate and binary logistic regression models were used to analyze independent risk factors for MDRO infections in patients with AIBDs. Differences between the MDRO infection group and common bacterial infection group were analyzed by using t test, Mann-Whitney U test and chi-square test. Results:Totally, 271 patients with AIBDs accompanied by wound infections were included, including 159 males (58.7%) and 112 females (41.3%), and 142 patients (52.4%) were aged over 60 years. Most patients with AIBDs were diagnosed with pemphigus vulgaris (131 cases, 48.3%), or bullous pemphigoid (99 cases, 36.5%). Bacterial culture was positive in all the patients, and 74 (27.3%) were infected with MDRO; a total of 108 strains of MDRO were detected, with relatively high detection rates of Staphylococcus (82 strains, 75.9%) and Enterobacter (15 strains, 13.9%). Significant differences were observed between the MDRO infection group and the common bacterial infection group in the duration of hospitalization, involved body surface area, proportions of patients self-modificating drug dosage, proportions of patients topically using antibiotic ointments, proportions of patients using immunosuppressants, duration of glucocorticoid use, maximum dose of glucocorticoids and the first albumin level at admission (all P < 0.05), while there were no significant differences in the gender, age, proportions of patients at first hospitalization, types of AIBDs, duration of education, body mass index, disease duration, proportions of smoking patients, proportions of drinking patients, proportions of patients with comorbid chronic diseases, surgical history, prevalence of hypoalbuminemia, prevalence of mucosal involvement, proportions of patients receiving topical glucocorticoids, proportions of patients using biological agents, duration of antibiotic use, and the first total protein level at admission between the two groups (all P > 0.05). Logistic regression analysis showed that the use of topical antibiotic ointments, use of immunosuppressants, maximum dose of glucocorticoids, and self-modification of drug dosage were independent risk factors for MDRO infections (all P < 0.05) . Conclusions:The patients with AIBDs were prone to develop MDRO infections in wounds, and Staphylococcus infections were the most common. The use of topical antibiotic ointments, use of immunosuppressants, high dose of glucocorticoids, and self-modification of drug dosage may increase the risk of infections in patients with AIBDs.

Background and purpose:Tumor-associated macrophages(TAM)as the main stromal cells in the tumor microenvironment play an important role in tumor progression.This study aimed to explore the clinical significance of M1 type TAM infiltration in hepatocellular carcinoma(HCC).Methods:We collected tissue paraffin samples from 320 HCC patients who underwent surgery at the Affiliated Nantong Hospital Three of Nantong University from January 2012 to December 2020.Immunohistochemical methods were used to detect the distribution of CD86 labeled M1 type TAM in HCC tissues,and positive cell density was calculated.Groups were established according to cell density,high-density group had cells with greater than average density(29 cells/mm2),and low-density group had cells with less than or equal to average density.The correlation and prognostic significance of M1 TAM density with clinicopathologic features and tumor infiltrating CD8+T lymphocytes of HCC were analyzed.Using immunohistochemistry to detect the expression of programmed death ligand-1(PD-L1),the cases were divided into four groups based on the cell density of CD86 and PD-L1.In the CD86+high-density group,PD-L1 high-density(CD86highPD-L1high)and PD-L1 low-density(CD86highPD-L1low)groups were included.In the CD86+low-density group,the PD-L1 high-density(CD86lowPD-L1high)and PD-L1 low-density(CD86lowPD-L1low)groups were included.We analyzed the prognostic significance of CD86+M1 type TAM density combined with PD-L1 expression.This study was approved by the Ethics Committee of Affiliated Nantong Hospital Three of Nantong University(ethics number:EK2022005).Results:CD86+M1 type TAM was mainly distributed in the tumor stroma.Its high-density rate was 44.7%(143/320).The density of CD86+M1 type TAM was positively correlated with tumor infiltrating CD8+T lymphocyte density(P<0.001)and negatively correlated with hepatitis B virus surface antigen(HBsAg)positivity(P=0.003),and had no significant correlation with clinical and pathological features such as patient age,gender,cirrhosis,tumor size,histological grading and microvascular invasion.The CD86+M1 type TAM high-density group had better overall survival(OS)and disease-free survival(DFS)than the low-density group,and the differences were statistically significant(all P<0.001).Multivariate Cox proportional hazards regression model analysis showed that low-density CD86+M1 type TAM was an independent risk factor for evaluating OS and DFS(OS:HR=1.468,P=0.022;DFS:HR=2.233,P<0.001).The CD86highPD-L1high group had poor OS and DFS than the CD86highPD-L1low group,and the differences were statistically significant(both P<0.05).The CD86lowPD-L1high group had poor OS and DFS than the CD86lowPD-L1low group.The difference in OS between the two groups was statistically significant(P<0.05),while the difference in DFS was not statistically significant.Conclusion:The presence of high-density CD86+M1 type TAM in HCC tissue suggests a good prognosis and is an independent prognostic factor.Expression of PD-L1 in HCC tissue suggests increased invasiveness and poorer prognosis.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

From October 2021 to February 2023, we retrospectively analyzed the clinical and laboratory data of six patients (three male and three female, median age: 54 years, age range: 29-73 years) with mast cell leukemia (MCL) diagnosed in the First Affiliated Hospital of Soochow University (The Mastocytosis Collaborative Network of China). All patients had acute MCL, with at least one C-finding present. The main clinical presentations were hypoalbuminemia ( n=4), fatigue ( n=3), fever ( n=2), abdominal discomfort ( n=2), osteolytic lesions ( n=2), dizziness ( n=1), skin flushing ( n=1), and weight loss ( n=1). Splenomegaly and lymphadenopathy were noted in six and three patients, respectively. Six patients were strongly positive for CD117, five were positive for CD30 and CD25, and four were positive for CD2. Four patients had a normal karyotype and two patients had an abnormal karyotype. Gene mutations were detected in 4/6 cases. The median serum tryptase level was 24.9 (range: 20.1-171.9) μg/L. Two patients were treated with venetoclax and azacitidine for induction (one patient achieved partial remission by combination with afatinib, while there was no remission after combination with dasatinib in the other patient). Two patients did not achieve complete remission despite treatment with cladribine and imatinib, respectively. One patient treated with interferon combined with glucocorticoids was lost to follow-up, and one patient abandoned treatment. The follow-up time ranged from 1.1 to 21.7 months. Three patients died and two survived. Overall, MCL is a rare subtype of systemic mastocytosis with heterogeneous clinical course, and these patients have poor outcome. A better understanding of the clinical characteristics, treatment, and prognosis of MCL is urgently needed.

Objective To investigate the expression levels and clinical significance of absolute counts of lymphocyte subsets and immunoglobulins (Ig) in peripheral blood of children with autism spectrum disorder (ASD). Methods Seventy-five children with ASD were selected as study group, and another 75 healthy children who underwent physical examination were selected as control group. Flow cytometry was used to detect the absolute counts of lymphocyte subsets (CD3+, CD4+, CD8+, CD19+, CD56+CD16+) and IgA, IgG, IgM levels in peripheral blood of both groups of children. Pearson correlation analysis was used to explore the correlation between each detection index and the total score of the Childhood Autism Rating Scale (CARS). Results The number of absolute counts of CD3+ and CD4+ in the study group were (62.49±8.71) and (34.87±7.86) in one μL, respectively, which were separately lower than (67.73±5.11) and (39.56±4.60)]in one μL in the control group (

OBJECTIVE To study the effects of Wubao capsule on airway inflammation in asthmatic model mice by regulating upstream and downstream cytokines of type Ⅱ innate lymphoid cells (ILC2s). METHODS Totally 40 female BABL/c mice were randomly divided into normal group, model group, positive control group (dexamethasone 1 mg/kg), Wubao capsule low-dose and high-dose groups (0.5, 1 g/kg), with 8 mice in each group. Asthma models were induced by ovalbumin (OVA) sensitization and nebulization. Each group was given normal saline or drug intragastrically for 7 consecutive days. The contents of IgE and OVA-IgE in serum, the contents of interleukin 5 (IL-5), IL-9, IL-13, IL-25, IL-33, thymic stromal lymphopoietin (TSLP) and mucin 5AC (MUC5AC) in bronchoalveolar lavage fluid (BALF) were determined by ELISA. HE staining was used to observe the pathological changes of lung tissues in mice. PAS staining was used to observe the changes of goblet cell proliferation in each group. The number of ILC2s in lung tissue was determined by flow cytometry (except for Wubao capsule low-dose group). RESULTS Compared with model group, the contents of IgE and OVA-IgE in serum and the contents of IL-5, IL-9, IL-13, IL-25, IL-33, TSLP and MUC5AC in BALF were significantly reduced in Wubao capsule high-dose and low-dose groups (P<0.01). The infiltration of inflammatory cells and the thickening of basement membrane in lung tissue was alleviated to varying degrees, and the proliferation of goblet cells was inhibited; the number of ILC2s in lung tissues of mice in Wubao capsule high-dose group was significantly reduced (P<0.01). CONCLUSIONS Wubao capsule could effectively reduce the number of ILC2s in lung tissue, the contents of upstream and downstream cytokines of ILC2s in BALF of asthmatic model mice, so as to inhibit the airway inflammation and improve asthma.

Objective:To analyze the costs and effectiveness of five common screening modes and genetic screening for thalassemia in China in order to find the optimal way and provide evidence for the implementation of thalassemia prevention and control projects in Hunan Province.Methods:From June 2020 to April 2021, 12 971 couples from 14 cities and autonomous prefectures in Hunan Province were selected as the study population. The diagnosis of thalassemia was based on the results of genetic testing. Results of routine blood test and hemoglobin electrophoresis were collected and analyzed. The efficacy of five screening modes, at the cut-off value of <80 fl or 82 fl for the mean corpuscular volume (MCV), was analyzed by positive predictive value, negative predictive value, Jorden index and cost-effectiveness ratio. Sensitivity analysis was used to assess the feasibility of genetic screening at different costs after fixing the costs of routine blood and hemoglobin electrophoresis. The five thalassemia screening models are as follows: Mode 1: The woman had a blood routine test first. If the result was positive, the spouse required a blood routine test. If both results were positive, a thalassemia gene test should be offered to the couple. Mode 2: Both husband and wife were screened by blood routine and hemoglobin electrophoresis. If one or both of them were positive, both would be tested for thalassemia gene. Mode 3: The couple received blood routine tests initially. If either was positive, both should receive hemoglobin electrophoresis testing. If either was positive, both parties will conduct thalassemia gene testing. Mode 4: The woman was screened by blood routine and hemoglobin electrophoresis. If any one of them was positive, the woman would be tested for thalassemia gene. If the gene test result was positive, the spouse should receive thalassemia gene. Mode 5: Both spouses conducted a blood routine test. If either was positive, both would conduct hemoglobin electrophoresis test. If both were positive, both spouses should receive thalassemia gene testing. Gene testing mode: The woman would be tested for thalassemia, and her spouse would have thalassemia test too if her result was positive.Results:When using MCV<80 fl as the cut-off for diagnosing thalassemia, the Youden indices of the five prenatal screening modes in Hunan Province were 0.551, 0.639, 0.898, 0.555 and 0.356, while when using MCV<82 fl as the cut-off, the Youden indices were 0.549, 0.629, 0.851, 0.548 and 0.356. When the MCV cut-off value was <80 fl, the missed diagnosis rates of the five screening modes were 44.44%, 0.00, 0.00, 18.52% and 62.96%, and the cost-effectiveness ratios were 21 709, 250 939, 76 870, 138 463 and 92 860 yuan (RMB)/couple, respectively. When the price of genetic testing was lower than 55 yuan (RMB), the cost-effectiveness ratio of genetic screening was lower than that of Mode 3.Conclusions:MCV<80 fl can be considered as the positive criteria in blood routine screening for thalassemia in Hunan Province, and the cost-effectiveness ratio of Mode 3 (the couple received blood routine tests initially. If either was positive, both should receive hemoglobin electrophoresis testing. If either was positive, both parties will conduct thalassemia gene testing) is the best. Genetic screening has certain advantages with the decreasing price.
