Fitting Degrees of Animal Models of Diarrhea-irritable Bowel Syndrome with Clinical Characteristics of Western Medicine and Traditional Chinese Medicine / 中国实验方剂学杂志

Diarrhea-irritable bowel syndrome （IBS-D） is one of the common functional bowel diseases in clinical practice. Since it pathogenesis is complex and has not been fully elucidated， effective treatment methods remains to be developed for this disease. Establishing the animal models of IBS-D in accordance with the clinical characteristics of traditional Chinese medicine （TCM） and Western medicine helps to reveal the pathogenesis of this disease and improve the treatment plan. The fitting degree of an animal model with clinical characteristics is an indicator to evaluate the effectiveness of the animal model in simulating the disease characteristics of Western medicine and the syndromes of TCM based on the latest diagnostic standards. By reviewing the relevant articles about the animal models of IBS-D， we discovered that rats were the preferred animals for modeling， and the models were mainly induced by single factors， double factors， or the combination of multiple factors. The established animal models mainly present symptoms or signs associated with visceral hypersensitivity or/and gastrointestinal motility abnormalities. The single factor-induced rat models of IBS-D had high fitting degrees with the clinical characteristics of Western medicine but low fitting degrees with the TCM syndromes. The animal models induced by two or more factors had high but varied fitting degrees with the clinical characteristics of Western medicine. In addition， the animal models of IBS-D considering TCM syndromes mainly focuses on the syndrome of liver depression and spleen deficiency， and few models were established for the syndromes of spleen-kidney Yang deficiency， spleen-stomach dampness-heat， spleen deficiency and dampness excess， and cold and heat in complexity. Therefore， it is essential to improve the existing or develop new animal models of IBS-D in the future， so as to provide more tools for deciphering the mechanisms of TCM and Western medicine and developing treatment methods for this disease.

Clinical Characteristics and Potential Risk Factors Analysis of Liver Injury Related to Epimedii Folium Preparation / 中国实验方剂学杂志

ObjectiveThis paper aims to analyze the clinical characteristics and medication rationality of liver injury related to Epimedii Folium preparation （EP） and explore the possible risk factors of liver injury， so as to provide a reference for the safe clinical application of Epimedii Folium （EF）. MethodA retrospective analysis was conducted on liver injury cases related to EP from 2012 to 2016. ResultThe number of reported liver injury cases and the proportion of severe cases related to the use of EP show an increasing trend， indicating the objective existence of liver injury caused by EP. There are more cases of liver injury related to EP in women than in men， with an onset age range of 15-91 years old and a median onset age of 60 years old （median onset ages for men and women are 59 and 60 years old， respectively）. The time span from taking EP alone to the occurrence of liver injury is 1-386 days， with a median of 38 days. The time span from taking both EP and Western medicine to the occurrence of liver injury is 1-794 days， with a median of 34 days. EF-related liver injury preparations are mostly composed of traditional Chinese medicines that promote immunity and tonify the liver and kidney， indicating that immune stress in the body may be the mechanism of liver injury caused by the use of EP alone or in combination. There is no increasing trend of toxicity with time or dose in the liver injury caused by EP. By further exploring its risk factors， it is found that patients have unreasonable medication methods such as excessive dosage， repeated use， and multi-drug combination， which may also be one of the important risk factors for EF-related liver injury. ConclusionEP has a certain risk of liver injury and should be emphasized in clinical diagnosis and treatment. Immune stress may be the mechanism of liver injury caused by EP， and in clinical use， it is necessary to be vigilant about the risk of liver injury caused by unreasonable use and combined use with Western medicine.

Clinical characteristics and outcomes of 176 patients with acute necrotizing mediastinitis: A retrospective cohort study / 中国胸心血管外科临床杂志

@#Objective To investigate the etiology, symptoms, diagnosis, surgical treatment, and outcomes of acute necrotizing mediastinitis (ANM) in order to guide future diagnosis and treatment of ANM. Methods The clinical data of patients with ANM referred to West China Hospital, Sichuan University from March 2012 to April 2021 were retrospectively analyzed. The etiology, clinical manifestations, demographic characteristics, bacterial culture results, surgical approach and prognostic factors of these patients were summarized. Results A total of 176 patients were enrolled in this study. The median age was 60 ( 0-84) years. There were 124 (70.5%) males and 52 (29.5%) females. The most common origin of infection was neck (n=66, 37.5%). The most common symptom was fever (n=85, 48.3%). Streptococcus constellatus represented the most common pathogens in secretion culture. Surgical treatment was administered to 119 (67.6%) patients through different approaches, including 54 (30.7%) patients of cervical approach, 9 (5.1%) patients of thoracotomy, 18 (10.2%) patients of video-assisted thoracoscopic surgery (VATS), 7 (4.0%) patients of cervical combined with thoracotomy, 30 (17.0%) patients of cervical combined with VATS, and 1 (0.6%) patient of subxiphoid approach. Among this cohort, 144 (81.8%) patients were cured, while 32 (18.1%) patients died. Age-adjusted Charlson comorbidity index (OR=2.95, P=0.022), perioperative sepsis (OR=2.84, P=0.024), and non-surgical treatment (OR=2.41, P=0.043) were identified as independent predictors of poor outcomes. Conclusion For patients with corresponding history and manifestations of ANM, it is crucial to go through imaging examination to confirm the presence of an abscess and guide the selection of surgical approach. Once the diagnosis of ANM is made, it is imperative to promptly perform surgical intervention for effective drainage. Our study highlights the significance of age-adjusted Charlson comorbidity index, perioperative sepsis and surgical treatment in predicting patients’ outcomes.

Clinical characteristics of patients with puerperal schizophrenia / 四川精神卫生

BackgroundWomen may develop severe symptoms of stress disorder following childbirth， which may be exposed to a risk of developing mental health problems， and even lead to the recurrence of the illness in female patients with schizophrenia， while comparatively limited research has been undertaken concerning the clinical characteristics and treatment of puerperal schizophrenia in China. ObjectiveTo explore the clinical characteristics of puerperal schizophrenia， so as to provide references for the clinical treatment. MethodsA total of 24 patients with puerperal schizophrenia who were hospitalized in the female ward of adult psychiatry department of the Affiliated Brain Hospital of Guangzhou Medical University from 2012 to 2020 and met the Diagnostic and Statistical Manual of Mental Disorders， fourth edition （DSM-IV） diagnostic criteria for schizophrenia were included as puerperal group. Another 48 non-puerperal women with schizophrenia were concurrently enrolled as control group. Then the basic data， scores on Positive and Negative Symptom Scale （PANSS） and the discharge medication were recorded. ResultsThe percentages of newly onset and positive family history of psychosis in puerperal group were larger than those in control group， with statistical significance （χ2=9.321， 5.240， P<0.05 or 0.01）. Puerperal group scored higher on PANSS excitement factor （t=-2.220， P<0.05） and lower on negative factor （t=3.377， P<0.01） compared with control group. In terms of discharge medication， puerperal group reported a higher dosage of antipsychotic drugs （t=-2.095， P<0.05）， and a larger proportion of combined use of benzodiazepines or antidepressants （χ²=21.316， 5.114， P<0.05 or 0.01） compared with control group， with statistical significance. ConclusionPatients with puerperal schizophrenia display increased ratings of excitement symptoms and decreased ratings of negative symptoms， which necessitates the use of high doses of antipsychotic drugs， and combined use of benzodiazepines and antidepressants.

Características epidemiológicas y clínicas autorreportadas en pacientes con obesidad y COVID-19: un estudio de corte transversal / Epidemiological and clinical characteristics self-reported in patients with obesity and COVID-19 disease: a cross-sectional study

RESUMEN INTRODUCCIÓN En Argentina, la obesidad en adultos es una problemática con una prevalencia media de 25,4%. En la relación entre COVID-19 y obesidad, se observa mayor prevalencia de sobrepeso/obesidad y enfermedad severa entre los pacientes con COVID-19. Por ello, el objetivo del estudio fue conocer las características clínicas y epidemiológicas en pacientes con diagnóstico de obesidad sobrevivientes a la infección por SARS-CoV-2. MÉTODOS Se realizó un estudio observacional descriptivo y analítico de corte transversal. Se aplicó una encuesta autoadministrada. RESULTADOS La mediana de edad fue 41 años, y hubo un 69,9% de mujeres. Los síntomas de presentación más prevalentes fueron astenia (86,7%), anosmia (64,5%) y tos (64%). Con respecto a los síntomas persistentes luego de las 12 semanas del diagnóstico, los más prevalentes fueron astenia (52,9%), trastornos de sueño (32,4%) y falta de concentración/memoria (31,7%). Hubo mayor riesgo en mujeres (OR: 2,86; IC95%: 2,23-3,67) con obesidad (OR: 1,58; IC95%: 1,16-2,16). La enfermedad grave en obesos fue casi el triple comparado con no obesos (15,7% vs. 5,4%; p<0,001). DISCUSIÓN Los pacientes obesos mostraron síntomas de presentación que orientan a un estado inflamatorio sistémico, con disnea y tos más frecuentes, y tienen mayor prevalencia de enfermedad grave y neumonía, así como mayor riesgo de desarrollar síntomas persistentes, sobre todo si las personas son mujeres y sedentarias.

ABSTRACT INTRODUCTION In Argentina, obesity in adults is a problem with an average prevalence of 25.4%. The relationship between COVID-19 and obesity shows a higher prevalence of overweight/obesity and severe disease among patients with COVID-19. Therefore, the objective of the study was to know the clinical and epidemiological characteristics of patients diagnosed with obesity who survived SARSCoV- 2 infection. METHODS A descriptive and analytical cross-sectional observational study was carried out. A self-administered survey was applied. RESULTS The median age was 41 years and 69.9% were women. The most prevalent presenting symptoms were asthenia (86.7%), anosmia (64.5%) and cough (64%). Regarding persistent symptoms 12 weeks after diagnosis, the most prevalent ones were asthenia (52.9%), sleep disorders (32.4%) and lack of concentration/memory (31.7%). The risk was higher for women (OR: 2.865; CI95%: 2.23-3.67) with obesity (OR: 1.58; CI95%: 1.16-2.16). Severe disease in obese was almost threefold that in non-obese patients (15.7% vs. 5.4%; p<0.001). DISCUSSION Obese patients showed presenting symptoms that point to a systemic inflammatory state, with dyspnea and cough being more common, and have a higher prevalence of severe disease and pneumonia, as well as a higher risk of developing persistent symptoms, especially if they are women and sedentary.

Relationship between quality of life and sociodemographic, clinical and lifestyle characteristics of patients undergoing hemodialysis

Introduction: In chronic diseases, QoL depends on several factors such as the type and duration of the disease, its treatment and side effects, the severity of symptoms, medication effects, patient age, limitations and self-care capacity. In chronic kidney disease it has also become a measure of health outcome.Objective: assess the association between QoL and socioeconomic, lifestyle and clinical factors of patients on HD.Methods: This is a cross-sectional epidemiological census, carried out among 1,024 patients on hemodialysis from all hemodialysis units at the metropolitan region in the Espirito Santo's, Brazil . Sociodemographic, lifestyle and clinical characteristics data were used. QoL was assessed using the Short-Form health Survey-36 (SF-36). Data were analysed by multiple linear regression.Results: The best QoL was represented by mental health (72.16) and the worst QoL by the physical aspect (26.78). After multiple linear regression, predictors of QoL were identified, with emphasis on males, a predictor of better QoL for 5 of the 8 domains and the summaries of the physical and mental components. Education, associated with 5 domains, gives greater reference to income. Physical activity was a predictor of 7 of the 8 QoL domains and the summary of the physical component. Among the clinical variables, the number of complications is associated with 7 of the 8 domains and summaries of the physical and mental components.Conclusion: Male sex is highlighted as a predictor of better physical and mental health and elderly people with better mental health, despite the impairment in physical health. The absence of physical activity is associated with worse physical and mental health. Clinically, having 3 or more intradialytic complications was associated with worse physical and mental QoL

Clinical Characteristics of Geographic Tongue in Patients with Primary Sjögren's Syndrome / 中国实验方剂学杂志

ObjectiveTo analyze the clinical characteristics of geographic tongue in patients with primary Sjögren's syndrome （pSS）. MethodPatients with pSS treated in the China-Japan Friendship Hospital from December 2018 to October 2021 were enrolled and divided into different groups according to the presence of geographic tongue or the severity. Phi correlation analysis，Chi-square test， and Mann-Whitney test were used to analyze the clinical characteristics of patients with geographic tongue. ResultA total of 182 pSS patients were included in this study，including 75 （41.2%） patients with geographic tongue and 107 （58.8%） without geographic tongue. Partial exfoliation was more common than total exfoliation， and the anterior part of the tongue was the most common exfoliation site. The number of patients with severe geographic tongue was more than those with mild-to-moderate geographic tongue. Compared with pSS patients without geographic tongue，those with geographic tongue were more common in fissured tongue （92.0%/41.1%，χ2=48.491，P<0.05），red or crimson tongue （48.0%/23.3%，χ2=12.009，P<0.05），Yin deficiency syndrome （100.0%/43.9%，χ2=62.739，P<0.05），and Qi deficiency syndrome （94.7%∶50.5%，χ2=40.046，P<0.05），less common in phlegm-dampness syndrome （33.3%/72.0%，χ2=26.709，P<0.05），and showed higher proportions in hyperglobulinemia （89.3%/65.4%，χ2=13.547，P<0.01），ANA ≥1∶160 （78.1%/57.3%，χ2=8.227，P<0.01），and positive RF （51.4%/36.5%，χ2=3.877，P<0.05）. Compared with pSS patients with mild geographic tongue，pSS patients with moderate-to-severe geographic tongue had higher proportions in hyperglobulinemia （98.1%/68.2%，χ2=14.617，P<0.01），positive anti-CENP-B （26.0%/4.8%，χ2=4.214，P<0.05），and reduced complement 3 （26.4%/4.5%，χ2=4.647，P<0.05）. The geographic tongue was positively associated with fissured tongue （φ=0.531），Yin deficiency syndrome （φ=0.587），and Qi deficiency syndrome （φ=0.469），negatively associated with phlegm-dampness syndrome （φ=-0.447），and weakly associated with tongue color （φ<0.4）. There was no statistical difference in the disease activity index between patients with or without geographic tongue and severity. ConclusionMore than 40% of pSS patients had geographic tongue accompanied by fissured tongue. Geographic tongue is positively associated with Yin deficiency syndrome and Qi deficiency syndrome，and negatively associated with phlegm-dampness syndrome， indicating that treatment should be based on tonifying Qi and nourishing Yin. Compared with pSS patients without geographic tongue， those with geographic tongue may have higher positive rate of some immune indicators，which deserves further exploration.

Clinical Characteristics and Diagnostic Methods of Pulmonary Mucormycosis / 中山大学学报(医学科学版)

ObjectiveTo summarize the clinical features and prognosis of pulmonary mucormycosis （PM） in southern China， and to explore the diagnostic value of metagenomic next generation sequencing （mNGS） in PM. MethodsThe clinical manifestations， diagnosis， treatment and prognosis of patients diagnosed with PM in The First Affiliated Hospital of Sun Yat-sen University from January 1， 2019 to January 31， 2022 who had undergone mNGS detection in lung tissue or alveolar lavage fluid were collected retrospectively. A total of 14 patients with PM were included， including 4 patients with confirmed diagnosis and 10 patients with clinical diagnosis. ResultsAll patients had underlying medical conditions， with hematological malignancies and diabetes being the most common. The most common symptoms were fever （n = 10）， cough （n = 9） and shortness of breath （n = 9）. Consolidation was the most common sign of chest CT， followed by mass， mostly with cavity. On laboratory tests， decreased CD4+T lymphocytes， elevated CD8+T lymphocytes， and decreased CD4+/CD8+ ratio， and presentation with pleural effusion indicate poor prognosis. The positive rate of mNGS diagnosis was 78.5%， which was significantly higher than that of histopathology （50%）， fungus rapid fluorescence staining （61.5%） and fungal culture （23.1%） of bronchoalveolar lavage fluid. ConclusionsPulmonary mucormycosis is more likely to occur in patients with underlying diseases or who are immunocompromised. The clinical manifestations lack specificity. The low CD4/CD8 ratio and presentation of pleural effusion on CT imaging indicate poor prognosis of patients. mNGS is a rapid， convenient and sensitive method for the diagnosis of PM， which has advantages in the diagnosis of pulmonary mucormycosis.

Clinical Characteristics and Survival Analysis of Carbapenem-Resistant Pseudomonas Aeruginosa Colonized or Infected Patients with Hematological Disorders / 中国实验血液学杂志

OBJECTIVE@#To observe the clinical characteristics and impact on mortality of carbapenem-resistant Pseudomonas aeruginosa (CRPA) colonized or infected patients with hematological disorders in order to provide evidence for the prevention and treatment of CRPA.@*METHODS@#The patients who were colonized or infected with CRPA in the Department of Hematology of The First Affiliated Hospital of Zhejiang Chinese Medical University from January 2020 to March 2021 were selected as the research subjects, the clinical data such as hospitalization time, primary disease treatment regimen, granulocyte count, previous infection and antibiotic regimen of these patients were analyzed, meanwhile, antibiotic regimen and efficacy during CRPA infection, 30-day and long-term survival were also analyzed.@*RESULTS@#A total of 59 patients were included in this study, and divided into CRPA infection group (43 cases) and CRPA colonization group (16 cases). Univariate logistic regression analysis showed that ECOG score (P =0.003), agranulocytosis (P <0.001), and exposure to upper than 3rd generations of cephalosporins and tigecycline within 30 days (P =0.035, P =0.017) were the high-risk factors for CRPA infection. Multivariate logistic regression analysis showed that ECOG score of 3/4 ( OR=10.815, 95%CI: 1.260-92.820, P =0.030) and agranulocytosis ( OR=13.82, 95%CI: 2.243-85.176, P =0.005) were independent risk factors for CRPA infection. There was a statistically significant difference in cumulative survival rate between CRPA colonization group and CRPA infection group ( χ2=14.134, P < 0.001). Kaplan-Meier survival analysis showed that the influencing factors of 30-day survival in patients with CRPA infection were agranulocytosis (P =0.022), soft tissue infection (P =0.03), and time of hospitalization before CRPA infection (P =0.041). Cox regression analysis showed that agranulocytosis was an independent risk factor affecting 30-day survival of patients with CRPA infection (HR=3.229, 95%CI :1.093-3.548, P =0.034).@*CONCLUSIONS@#Patients with hematological disorders have high mortality and poor prognosis after CRPA infection. Bloodstream infection and soft tissue infection are the main causes of death. Patients with high suspicion of CRPA infection and high-risk should be treated as soon as possible.

Analysis of incidence and clinical characteristics of osteonecrosis of femoral head in patients with systemic lupus erythematosus treated with glucocorticoid: A descriptive study based on a prospective cohort / 中国修复重建外科杂志

OBJECTIVE@#To describe the disease characteristics of osteonecrosis of the femoral head (ONFH) in patients with systemic lupus erythematosus (SLE) who experiencing prolonged glucocorticoid (GC) exposure.@*METHODS@#Between January 2016 and June 2019, 449 SLE patients meeting the criteria were recruited from multiple centers. Hip MRI examinations were performed during screening and regular follow-up to determine the occurrence of ONFH. The cohort was divided into ONFH and non-ONFH groups, and the differences in demographic baseline characteristics, general clinical characteristics, GC medication information, combined medication, and hip clinical features were compared and comprehensively described.@*RESULTS@#The age at SLE diagnosis was 29.8 (23.2, 40.9) years, with 93.1% (418 cases) being female. The duration of GC exposure was 5.3 (2.0, 10.5) years, and the cumulative incidence of SLE-ONFH was 9.1%. Significant differences ( P<0.05) between ONFH and non-ONFH groups were observed in the following clinical characteristics: ① Demographic baseline characteristics: ONFH group had a higher proportion of patients with body mass index (BMI)<20 kg/m 2 compared to non-ONFH group. ② General clinical characteristics: ONFH group showed a higher proportion of patients with cutaneous and renal manifestations, positive antiphospholipid antibodies (aPLs) and anticardiolipin antibodies, severe SLE patients [baseline SLE Disease Activity Index 2000 (SLEDAI-2K) score ≥15], and secondary hypertension. Fasting blood glucose in ONFH group was also higher. ③ GC medication information: ONFH group had higher initial intravenous GC exposure rates, duration, cumulative doses, higher cumulative GC doses in the first month and the first 3 months, higher average daily doses in the first 3 months, and higher proportions of average daily doses ≥15.0 mg/d and ≥30.0 mg/d, as well as higher full-course average daily doses and proportion of full-course daily doses ≥30.0 mg/d compared to non-ONFH group. ④ Combined medications: ONFH group had a significantly higher rate of antiplatelet drug use than non-ONFH group. ⑤ Hip clinical features: ONFH group had a higher proportion of hip discomfort or pain and a higher incidence of hip joint effusion before MRI screening than non-ONFH group.@*CONCLUSION@#The incidence of ONFH after GC exposure in China's SLE population remains high (9.1%), with short-term (first 3 months), medium-to-high dose (average daily dose ≥15 mg/d) GC being closely associated with ONFH. Severe SLE, low BMI, certain clinical phenotypes, positive aPLs, and secondary hypertension may also be related to ONFH.

A comparative study of the clinical characteristics of spotted fever and severe fever with thrombocytopenia syndrome / 中国热带医学

@#Abstract: Objective To investigate the differences in epidemiological and clinical characteristics of patients with spotted fever (SF) and severe fever with thrombocytopenia syndrome (SFTS). Methods A total of 86 patients with SF and 113 patients with SFTS who were laboratory-confirmed in the second-level and above hospitals in Lu'an City from January 2017 to January 2022 were selected. The basic data, epidemiological history, clinical data and laboratory test results of the two diseases were retrospectively analyzed for comparison. Results The proportion of male in SF group was 32.56% (28/86), and the proportion of male in SFTS group was 53.98% (61/113), the difference was statistically significant (χ2=9.067, P<0.01). The proportions of abdominal pain and diarrhea in the SF group were (3.49%, 3/83) and (21.24%, 24/113), which were significantly lower than corresponding (6.98%, 6/86) and (46.90%, 53/113) in the SFTS group (χ2=13.121, 37.322, P<0.01). The incidences of rash and eschar in SF group were 95.35% (82/86) and 20.93% (18/86), which were significantly higher than corresponding 1.77% (2/113) and 0.88% (1/113) in SFTS group (χ2=175.311, 22.721, P<0.01). The levels of leukocytes, platelets and C-reactive protein in the SF group were significantly higher than those in the SFTS group, and the levels of transaminase, lactate dehydrogenase and D-dimer were significantly lower than those in the SFTS group, and the differences were statistically significant (all P<0.05). Conclusions The rash and inflammatory reaction are more obvious in SF patients, while the liver function, myocardial function and coagulation function are significantly impaired in SFTS patients.

Clinical characteristics and long -term prognosis of elderly onset Crohn 's disease / 中南大学学报(医学版)

OBJECTIVES@#With the increase in aging population in China, elderly Crohn's disease (CD) patients need to receive more attention. This study aims to explore the clinical characteristics and disease process of elderly onset CD (EOCD) patients in a single center.@*METHODS@#From January 2002 to January 2022, a total of 221 patients with CD from the Seventh Medical Center of Chinese PLA General Hospital were enrolled. According to the Montreal CD classification standard, the patients were further divided into 4 groups: an EOCD group (≥60 years old, n=25), a middle age onset CD (MOCD) group (40-59 years old, n=46), a young onset CD (YOCD) group (17-40 years old, n=131), and a childhood onset CD (COCD) group (6-16 years old, n=19). We compared the clinical characteristics and long-term prognosis among them.@*RESULTS@#Females were predominant in the EOCD group (15/25, 60%). The number of people without smoking in the EOCD group (80%) was lower than that in COCD group (100%), higher than that in the YOCD group (70.2%) and the MOCD group (69.6%) (all P<0.05). Patients with perianal diseases at diagnosis were rare in the EOCD group (0%), lower than that in the COCD group (21.1%) and the YOVD group (19.8%) (all P<0.05). Stenosis was the most common disease behavior in the EOCD group (63.0%), significantly higher than that in the COCD group (15.8%), the YOCD group (36.6%) and the MOCD group (43.5%) (all P<0.05). The EOCD group was easier to be misdiagnosed as tumor (24%), higher than that in the COCD group (0%), the YOCD group (6.9%) and the MOCD group (19.6%) (all P<0.05). The EOCD group was prone to comorbidities (52%), and 20% of them were complicated with multiple comorbidities (P<0.05). During the follow-up, the all-cause mortality of EOCD was 12%, and the CD-related mortality was 8%, which was significantly higher than the other groups (all P<0.05). The use of immunosuppressants in the EOCD group (4.8%) was lower than that in the COCD group (12.8%), the YOCD group (16.8%) and the MOCD group (16.1%), but there was no statistical significance among the 4 groups (P=0.467). In addition, there was no significant difference in the rate of intestinal resection among the 4 groups (P=0.062).@*CONCLUSIONS@#In EOCD patients, females were predominant, smoking was less common, and they were prone to comorbidity. At the initial stage of diagnosis, it is easy to be misdiagnosed as tumor, and the disease behavior mainly showed stricture type, less complicated with perianal diseases. During the follow-up, all-cause mortality and CD-related mortality of EOCD patients were significantly higher than those of the non-elderly onset CD patients.

Clinical Characteristics and Survival Analysis of Patients with Plasma Cell Leukemia / 中国实验血液学杂志

OBJECTIVE@#To investigate the clinical characteristics, therapeutic response and prognosis of patients with plasma cell leukemia (PCL) and improve the understanding of this disease.@*METHODS@#The clinical manifestations, laboratory tests and treatment response of 27 patients with plasma cell leukemia treated in The Second Hospital of Shanxi Medical University from December 2010 to August 2019 were analyzed retrospectively, and their clinical characteristics were summarized. Kaplan-Meier method was used for survival analysis.@*RESULTS@#There were 18 cases of primary plasma cell leukemia (pPCL) and 9 cases of secondary plasma cell leukemia (sPCL). The male to female ratio was 1.7∶1. The median age was 62 years old. The first manifestations were bone pain, fatigue, fever, splenomegaly and bleeding, and a large number of plasma cell infiltration was observed in the morphological examination of peripheral blood and bone marrow cells. 13 cases were detected by immunotyping and all of them expressed CD38/CD138. 8 cases underwent karyotype analysis, and 3 cases were normal, clonal abnormalities occurred in 5 cases. FISH detection was performed in 12 cases, of which 8 cases were abnormal. In 17 cases of bortezomib based chemotherapy, the ovevall response rate was 52.9%, which was higher than that in the non-bortezomib group, but there was no significant difference between the two groups (P =0.242). The overall median survival time of 27 patients was 6.4 months, the median progression-free survival time was 3.5 months, and the median survival time of patients with pPCL and sPCL was 8.2 months and 2.4 months, respectively, the difference between the two groups was statistically significant (P =0.031).@*CONCLUSION@#PCL is highly invasive and has diverse clinical manifestations, and is not sensitive to traditional chemotherapy. The median survival time of patients with pPCL is relatively longer than that of patients with sPCL. The chemotherapy regimen based on bortezomib improves the treatment effectiveness and prolongs the survival time of PCL patients.

Expression and Clinical Significance of Exosome Derived MiR-181b-5p in Children with Acute Lymphoblastic Leukemia / 中国实验血液学杂志

OBJECTIVE@#To explore the expression level of exosome derived miR-181b-5p in different disease stages of children with acute lymphoblastic leukemia and its relationship with clinical characteristics.@*METHODS@#Bone marrow plasma samples of 86 children with ALL were collected. Exosomes were extracted by exosome extraction kit, and RNA in exosomes was extracted by TRIzol method. The levels of miR-181b-5p in the blood plasma exosomes of the patients in the newly diagnosed group, relapse group, remission group and control group were detected by qRT- PCR. The difference of miR-181b-5p expression level in each group was compared and analyzed, and the relationship between miR-181b-5p expression level and clinical characteristics was analyzed.@*RESULTS@#The expression level of exosomal miR-181b-5p in the newly diagnosed group and the relapsed group was significantly lower than that in the remission group and the control group (P< 0.05). The expression level of exosomal miR-181b-5p in T-ALL children was higher than that in B-ALL children (P<0.05). The expression level of plasma exosomal miR-181b-5p in male children was higher than that in female children (P<0.01).@*CONCLUSION@#Exosome derived miR-181b-5p changes dynamically in the course of ALL children, and can be used as a marker miRNA to monitor disease status. Exosomes can transmit information in the tumor microenvironment and serve as a potential carrier for biomolecular targeted therapy.

Clinical characteristics and prognostic factors of patients with Philadelphia-negative myeloproliferative neoplasm accelerated/blast phase / 中华血液学杂志

Objective: To evaluate the clinical characteristics and prognostic factors of patients with Philadelphia-negative myeloproliferative neoplasm-accelerated phase/blast phase (MPN-AP/BP) . Methods: A total of 67 patients with MPN-AP/BP were enrolled from February 2014 to December 2021 at the Institute of Hematology and Blood Diseases Hospital, Chinese Academy of Medical Sciences. Their clinical features and prognostic factors were analyzed retrospectively. Results: ① Sixty-seven patients with MPN-AP/BP with a median age of 60 (range, 33-75) years, including 31 males (46.3% ) and 36 females (53.7% ) , were analyzed. Forty-eight patients progressed from primary myelofibrosis (PMF) , and 19 progressed from other myeloproliferative neoplasms (MPNs) , which included polycythemia vera, essential thrombocythemia, and MPN unclassifiable. Patients who progressed from PMF had higher lactate dehydrogenase (LDH) levels than those who progressed from other MPNs (925.95 vs. 576.2 U/L, P=0.011) , and there were higher proportions of patients who progressed from PMF with splenomegaly (81.4% vs. 57.9% , P=0.05) , a myelofibrosis grade of ≥2 (93.6% vs. 63.2% , P=0.004) , and a shorter duration from diagnosis to the transformation to AP/BP (28.7 vs. 81 months, P=0.001) . ② JAK2V617F, CALR, and MPLW515 were detected in 41 (61.2% ) , 13 (19.4% ) , and 3 (4.5% ) patients, respectively, whereas 10 (14.9% ) patients did not have any driver mutations (triple-negative) . Other than driver mutations, the most frequently mutated genes were ASXL1 (42.2% , n=27) , SRSF2 (25% , n=16) , SETBP1 (22.6% , n=15) , TET2 (20.3% , n=13) , RUNX1 (20.3% , n=13) , and TP53 (17.2% , n=11) . The ASXL1 mutation was more enriched (51.1% vs. 21.1% , P=0.03) , and the median variant allele fraction (VAF) of the SRSF2 mutation (median VAF, 48.8% vs. 39.6% ; P=0.008) was higher in patients who progressed from PMF than those who progressed from other MPNs. ③ In the multivariate analysis, the complex karyotype (hazard ratio, 2.53; 95% confidence interval, 1.06-6.05; P=0.036) was independently associated with worse overall survival (OS) . Patients who received allogeneic stem cell transplantation (allo-HSCT) (median OS, 21.3 vs. 3 months; P=0.05) or acute myeloid leukemia-like (AML-like) therapy (median OS, 13 vs. 3 months; P=0.011) had significantly better OS than those who received supportive therapy. Conclusion: The proportions of patients with PMF-AP/BP with splenomegaly, myelofibrosis grade ≥2, a higher LDH level, and a shorter duration from diagnosis to the transformation to AP/BP were higher than those of patients with other Philadelphia-negative MPN-AP/BP. The complex karyotype was an independent prognostic factor for OS. Compared with supportive therapy, AML-like therapy and allo-HSCT could prolong the OS of patients with MPN-AP/BP.

Clinical characteristics of 57 cases of clear cell papulosis / 中华皮肤科杂志

Objective:To analyze and summarize clinical and pathological characteristics of clear cell papulosis (CCP) .Methods:Clinical data were collected from 57 children with CCP, who were diagnosed in Department of Dermatology, Children′s Hospital of Chongqing Medical University from November 2014 to March 2022, and their clinical and pathological characteristics were analyzed.Results:Among the 57 patients, 30 were males and 27 were females; their age ranged from 6 months to 7 years and 10 months; the age at onset ranged from 1 to 74 months, and 39 (68.4%) experienced onset of disease in infancy; the course of disease ranged from 1 to 84 months. Skin lesions mainly manifested as millet- to soybean-sized roundish white macules or short bar-like white macules measuring 1 - 2 cm in length. Most patients (49 cases, 85.9%) had skin lesions less than 20 in number. The most common location of skin lesions was the lower abdomen (35 cases, 61.4%), followed in turn by chest or upper abdomen (34 cases, 59.6%), anterior axilla or armpit (17 cases, 29.8%), and vulva (11 cases, 19.3%). Short bar-like white macules predominated on the chest or upper abdomen (23/34, 65.7%) and anterior axilla or armpit (10/17), roundish white macules predominated on the lower abdomen (30/35, 85.7%), and the vulvar lesions all manifested as roundish white macules. Histopathological findings showed that slightly larger cells with abundant clear cytoplasm were scattered in or above the basal layer of the epidermis, and these cells were positive for cytokeratin 7, carcinoembryonic antigen, and periodic acid-Schiff staining.Conclusion:CCP mainly occurred in young children, roundish white macules predominated on the lower abdomen and vulva, and short bar-like white macules predominated on the chest or upper abdomen, as well as on the anterior axilla or armpit, indicating that CCP has strongly identifiable clinical features.

Epidemiological characteristics of Mycobacterium marinum infection cases in a hospital in Shandong province, 2019 to 2021 / 中华皮肤科杂志

Objective:To investigate epidemiological characteristics of Mycobacterium marinum infection cases in the Dermatology Hospital of Shandong First Medical University from January 2019 to December 2021. Methods:Data were collected from patients with Mycobacterium marinum infection in the Dermatology Hospital of Shandong First Medical University from January 2019 to December 2021. Demographic characteristics, clinical features and prognosis of patients were retrospectively analyzed. Differences between groups were analyzed using t test, Chi-square test and Fisher′s exact test; factors influencing the time to diagnosis (the time from the first appearance of skin manifestations to the diagnosis of Mycobacterium marinum infection in the hospital) longer than 12 months were analyzed using Chi-square test and multivariate logistic regression model, and the odds ratio ( OR) and 95% confidence interval (95% CI) were calculated. Results:From 2019 to 2021, a total of 373 cases of Mycobacterium marinum infection were diagnosed in the hospital, and the number of cases in 2021 was 4.06 times that in 2019; the male-to-female ratio was 1∶1.49, and their age was 54.24 ± 14.04 years. Among the 373 patients, 211 (56.57%) had a history of trauma caused by aquatic products (e.g., fishes, shrimps), of which 51 (24.17%) were stung by sea perch. Skin lesions involved unilateral limbs in 327 (87.67%) patients, only involved the hands or wrists in 188 (50.40%) patients, and 258 (69.17%) had multiple skin lesions. Among the 341 patients with treatment information, 105 (30.79%) were given one antibiotic, 214 (62.76%) received combination treatment with two antibiotics, and 15 (4.40%) were treated with three antibiotics. The response rate was 98.77% (321/325), and the time to diagnosis [ M ( Q1, Q3) ] was 5.03 (3.00, 8.37) months. Multivariate logistic regression analysis indicated higher proportions of males ( OR [95% CI]: 1.95[1.11 - 3.41], P = 0.02), patients aged > 55 years ( OR [95% CI]: 1.82[1.04 - 3.18], P = 0.04), patients with skin lesions only involving hands, arms or lower limbs ( OR [95% CI]: 3.48[1.83 - 6.61], P<0.001) among the patients whose time to diagnosis was longer than 12 months. Conclusions:The number of patients with Mycobacterium marinum infection was increased in the Dermatology Hospital of Shandong First Medical University year by year from 2019 to 2021, and fish sting wounds were the main cause of infection. The most common treatment regimen was the combination of two antibiotics, with a high efficacy profile.
