Objective To observe the clinical effects of cognitive behavioral therapy (CBT) combined with pulmonary rehabilitation on the treatment of patients with pneumoconiosis. Methods A total of 108 patients with pneumoconiosis were selected as the research subject using convenient sampling method. They were randomly divided into control group and CBT group, with 54 cases in each group. Patients in the control group were treated with conventional symptomatic treatment and pulmonary rehabilitation treatment for 12 weeks. While patients in the CBT group were treated with CBT treatment in addition to treatments of the control group. The therapeutic effect was analyzed. Results Before treatment, there was no statistical difference on score of Montreal Cognitive Assessment (MoCA), percentage of forced expiratory volume in one second to the predicted value (FEV₁%), forced expiratory volume in one second to force vital capacity ratio (FEV₁/FVC%), score of the Modified Medical Research Council Dyspnea Scale (mMRC), six minute walk distance (6MWD), Hospital Anxiety and Depression Scale (HADS) subscale scores of anxiety (HADS-A) and depression (HADS-D), and scores of Chronic Obstructive Pulmonary Disease Assessment Test (CAT), St. George's Respiratory Questionnaire (SGRQ), and serum levels of leptin, interleukin-6 (IL-6) and C-reactive protein (CRP) between the two groups (all P>0.05). After treatment, the score of MoCA, FEV₁%, FEV₁/FVC% and 6MWD increased (all P<0.05), while the scores of mMRC, HDS-A, HDS-D, CAT and SGRQ decreased (all P<0.05), and the levels of serum leptin, IL-6 and CRP decreased (all P<0.05) in the CBT group compared with the control group. Conclusion The combined treatment of CBT and pulmonary rehabilitation can better improve the cognitive ability, respiratory function, motor function, negative emotion and quality of life, and alleviate inflammatory response in patients with pneumoconiosis. It is of certain clinical application value.

Objective:This study aimed to investigate the clinical features and prognosis of Pseudomonas aeruginosa infection in patients with hematologic malignancies.Methods:This study retrospectively analyzed the clinical data of 197 patients with hematologic malignancies complicated with P. aeruginosa infection who were hospitalized in the Department of Hematology from January 01, 2019, to December 31, 2021. Patients were categorized into a susceptible group (CSPA infection group) and a drug-resistant group (CRPA infection group) based on their sensitivity to carbapenems, comparing the differences in clinical features between the two groups, and analyzing the risk factors and prognosis of CRPA infection.Results:Logistic regression analysis revealed that hospitalization days of >50 days ( P=0.010, OR=3.581, 95% CI 1.356-9.457), history of antibiotic exposure ( P=0.008, OR=4.394, 95% CI 1.358-6.238), more than two courses of chemotherapy before infection ( P=0.006, OR=2.911, 95% CI 1.358-6.238) were independent risk factors for developing CRPA. The mortality rates were 12.8% (18/140) and 28.1% (16/57) in patients with CRPA and CSPA, respectively ( P=0.010). Logistic regression analysis revealed that bloodstream infection (BSI) ( P=0.039, OR=5.286, 95% CI 1.091-25.621) was an independent risk factor for hematologic malignancies and death from CRPA infection. Conclusion:Hospitalization for >50 days, history of antibiotic exposure, and >2 courses of chemotherapy before infection were independent risk factors for CRPA infection. Hematologic malignancies with CRPA infection had a high mortality rate, of which BSI was an independent risk factor for 30-day mortality from hematologic malignancies with CRPA infection.

Objective:To study the distribution and drug resistance of Carbapenem-Resistant Organism (CRO) and to analysis the risk factors of CRO 30-day mortality.Methods:A total of 181 patients with CRO infection diagnosed in Department of Hematology, Fujian Medical University Union Hospital from January 2018 to June 2020 were retrospectively investigated. The clinical and laboratory data of the patients were collected, the prognosis of patients diagnosed with CRO infection in day 30 was followed up, and the risk factors of prognosis were analyzed. The clinical significance of Carbapenem-Resistant Enterobacteriaceae (CRE) active screening was further evaluated in the CRE subgroup.Results:Among the total of 181 CRO isolates, 47.2% were CRE, 37.0% were Pseudomonas aeruginosa, and 32.6% were Klebsiella pneumoniae, which were highly resistant to carbapenem and had high MIC value, 76.8% (139/181) of CRO were MIC of imipenem resistance≥16 μg/ml. The main sources of isolates were blood and sputum. The 30-day all-cause mortality rates of patients with CRO or CRE infection were (41.4±3.7) % and (44.7±5.4) %, respectively. The COX multivariate regression analysis showed that the level of procalcitonin >0.2 ng/ml and the MIC value of imipenem resistance ≥ 16 μg/ml were independent risk factors for 30-day mortality of CRO infected patients. The CRE subgroup analysis showed that MIC value of imipenem resistance ≥16 μg/ml were independent risk factors for 30-day mortality of CRE infected patients. The 30-day cumulative survival rate of patients with CRE active screening was higher than the patients without CRE active screening [ (68.0±9.3) % vs (50.0±6.5) %, P=0.21]. Conclusion:The high MIC value of imipenem resistance isolates seriously affects the prognosis of patients with CRO infection in the hematology department, and the mortality rate was high. CRE active screening is expected for early prevention, early diagnosis, and early treatment for high-risk patients.

Cases of 2019-nCoV nucleic acid and antibody (IgM and IgG total antibody) after discharge from a hospital in Chongqing were continuously monitored. It was found that 5 cases of "re-positive" phenomenon, 5 cases of antibody were positive, and there was a trend of increasing with time. "Re-Positive" may be related to the following three factors. Children with asymptomatic infection had a long time of fecal detoxification.There were two consecutive nucleic acid tests "false negative" caused by various reasons.The virus clearance in patients was not complete, and the discharge standard was not conservative enough. The analysis of the causes of "Re-Positive" patients and the discussion of its infection will help us reveal more characteristics of this virus, and to provide a new basis for the discharge standard in the constantly updated diagnosis and treatment programme.

The identification of BCR-ABL fusion gene and the advent of tyrosine kinase inhibitors (TKI) targeting this mutation have promoted the landmark progress of diagnosis and treatment in chronic myeloid leukemia (CML), and have dramatically changed the treatment management and disease prognosis for CML patients. Most of the western countries hold a view that CML is cut and dried, but the situation is not the same in developing countries. Currently, more attention is paid to the discontinuation of TKI. In addition, deep challenges remain in the low- and middle-income countries. This paper reviews the treatment progress of CML and challenges in low-and middle-income countries reported at the 61st American Society of Hematology Annual Meeting.

Objective:In order to clarify the clinical characteristics and prognostic factors of AITL, we performed a retrospective analysis on the AITL patients at our hospital.Methods:The clinical data of 84 AITL patients diagnosed by lymph node pathology and immunohistochemistry in the Fujian Medical University Union Hospital between July 2009 and September 2018 were collected, and the prognostic factors affecting overall survivol (OS) and progression-free surrival (PFS) were retrospectively analyzed by Log-rank test and Cox progortional hazard regression model.Results:The median age of the 84 patients was 62 y (range, 39-86 y) with 52.4% of the patients aged >60 y. The male-to-female ratio was 2.5∶1. 80 patients (95.2%) presented with advanced-stage disease, and B symptoms were observed in 53 cases (63.1%) . Fifty-nine patients (70.2%) had intermediate high and high risk as per the international prognostic index (IPI) and 42 (50.0%) had intermediate high risk as per the prognostic index for peripheral T-cell lymphoma (PIT) . The treatment response could be evaluated in 61 of the 67 patients who underwent chemotherapy. The complete remission (CR/CRu) rate was 26.2% (16/61) , and the partial response rate was 41.0% (25/61) . The 5-year OS rate and PFS rate in 61 patients was 46.0% and 38.3%, respectively. The univariate analysis showed that age, IPI score, PIT score, hemoglobin level, presence of serous effusions, and chemotherapy influenced the OS. Age >60 y, hemoglobin level <110 g/L, and presence of serous effusions were poor prognostic factors for PFS. Multivariate analysis showed that age >60 y and serous effusion were independent poor prognostic factors of OS.Conclusions:AITL is a Non-Hodgkin lymphoma with high invasion, rapid progress, and poor prognosis. The age, IPI score, PIT score, hemoglobin levels, and serous effusion can be used as reference factors for predicting the prognosis in AITL patients.

Objective To investigate the clinical efficacy and mechanism of vacuum-assisted closure (VAC) in the preoperative and postoperative treatment of bedsore united with skin flap.Methods Twenty two cases with bedsore were randomly divided into experimental and control groups.In the control group,the surgery of flap was performed after the treatment of continuous negative pressure about 7-10 days and the VAC was not applied after operation.While in the experimental group,VAC was not used before operation.It was applied on flaps as soon as sutured the border of flap and decubitus ulcers and removed after 7-10 days.By comparing the general appearance of two groups,microvessel count and the detection rate of bacterial culture and other indicators,the clinical effects of two treatments were investigated and the preliminary mechanism was analyzed.Results After preoperative VAC treatment,11 cases of control group showed a little granulation tissue growth,less subcutaneous hematoma and wound effusion,increased microvessel count and negative bacterial culture.However,there were 4 cases of death cavity residual,subcutaneous hematoma and wound effusion,positive bacterial culture and another 4 cases of delayed healing with skin flap repairing bedsore.The application of VAC in experimental group showed close contact of flap with the basement,less effusion,increased microvessel count and negative bacterial culture.One case of skin flap had a small area of separation,after the dressing of skin and the flap survived.The other wounds healed by first intention.Conclusions The use of VAC to repair bedsore can reduce the number of operation,and it is beneficial to the flap survival.

Objective: To investigate the distribution and resistance of pathogens isolated from blood cultures in patients with hematological malignancies after chemotherapy in Union Hospital of Fujian Medical University so as to understand the real situation of blood stream infection (BSI) and provide the basis for rational use of antibiotics in clinic. Methods: The data of 657 strains isolated from blood culture specimens of patients with hematological malignancies from January 2013 to December 2016 were collected analyzed. Results: A total of 657 cases of blood culture positive bacterial strains were included in the study, involving 410 cases (62.4%) with single Gram-negative bacteria (G^- bacteria) , 163 cases (24.8%) with single Gram-positive bacteria (G⁺ bacteria) , 50 cases (7.6%) with single fungi. The most common 5 isolates in blood culture were Klebsiella pneumoniae (17.5%) , Escherichia coli (17.2%) , Coagulase negative staphylococci (CNS) (14.9%) , Pseudomonas aeruginosa (14.2%) and Staphylococcus aureus (3.5%) . The extended-spectrum beta-lactamase (ESBL) production rates of Klebsiella pneumoniae and Escherichia coli were 25.2% and 55.8%, respectively. ESBL producing strains were almost more resistant than non-ESBL producing strains. The resistance rates of Enterobacteriaceae to carbapenems, piperacillin/tazobactam and tigecycline were lower than 14.0%. The resistance rates of Pseudomonas aeruginosa to a variety of drugs were lower than 12.0%. Tigecycline-resistant Acinetobacter baumannii bacteria were not detected, and the resistance rates of Acinetobacter baumannii to cefixime and cefotaxime were 7.1%. Methicillin-resistant strains in CNS (MRCNS) and in Staphylococcus aureus (MRSA) accounted for 84.7% and 43.5%, respectively. Vancomycin, linezolid and tigecycline-resistant G⁺ bacteria were not detected. Conclusion The pathogens isolated from blood culture were widely distributed. Most of them were G^- bacteria, and the resistance to antibiotics was quite common. Furhermore, vancomycin, linezolid and tigecycline can be chosen empirically to treat patiens who ar suspected to have G⁺ bacterial BSI.
