  • Analysis of clinical and inflammatory characteristics and risk factors of severe asthma

    Objective To explore the clinical and inflammatory characteristics and risk factors of severe asthma to improve clinicians' awareness of the disease. Methods The general information of patients with asthma who visited the Department of Respiratory Medicine, the First Hospital of Shanxi Medical University from May 2018 to May 2021, as well as the diagnosis and treatment of asthma, personal history, comorbidities, auxiliary examination, asthma control test (ACT) score were collected. A total of 127 patients were included, including 40 in the severe asthma group and 87 in the mild-to-moderate asthma group. Chi-square test, independent sample t test and logistic regression were used to analyze the clinical characteristics, inflammatory markers and risk factors of severe asthma. Results Compared with the patients with mild to moderate asthma, the patients with severe asthma were more older (51.0±12.0 years vs 40.7±12.8 years, P<0.05), had more smokers (32.5% vs. 14.9%, P<0.05), and more males (67.5% vs. 40.2%, P<0.05). The patients with severe asthma got poor FEV1%pred [(56.1±23.8)% vs. (93.2±18.0)%, P<0.05] and FEV1/FVC [(56.7±13.2)% vs. (75.8±9.0)%, P<0.05)], and more exacerbations in the previous year (2.7±3.1 vs. 0.1±0.4, P<0.05), lower ACT score (14.4±3.7 vs. 18.0±5.0, P<0.05), and higher blood and induced sputum eosinophil counts [(0.54±0.44)×109/L vs. (0.27±0.32)×109/L, P<0.05; (25.9±24.2)% vs. (9.8±17.5)%, P<0.05]. There was no significant difference in the proportion of neutrophils in the induced sputum or FeNO between the two groups (P>0.05). Analysis of related risk factors showed that smoking (OR=2.740, 95%CI 1.053 - 7.130), combined with allergic rhinitis (OR=14.388, 95%CI 1.486 - 139.296) and gastroesophageal reflux (OR=2.514, 95%CI 1.105 - 5.724) were risk factors for severe asthma. Conclusions Compared with patients with mild to moderate asthma, patients with severe asthma are characterized by poor lung function, more exacerbations, and a dominant eosinophil inflammatory phenotype, which is still poorly controlled even with higher level of treatment. Risk factors include smoking, allergic rhinitis, and gastroesophageal reflux, etc.

  • COMPARATIVE STUDY ON THE MAIN BIOLOGICAL CHARACTERISTICS OF MARROW-DERIVED STROMAL CELLS AND CHONDROCYTES IN VITRO CULTURE IN RABBITS

    Objective To observe the main biological characteristics and chondrogenesis potency of bone marrow -derived stromal cells(MSCs) after cytokinesinduction or gene modification in vitro. Methods MSCs from an adult New Zealand white rabbit were isolated and cultivated, and then MSCs were divided into the common medium group(Group A, 15%FBS in DMEM), the induced group by cytokines (Group B), the transfected group(Group C)with adenovirus-hepatocyte growth factor transgene (adHGF). The medium of group B consisted of transforming growth factor-β1(TGF-β1,10 ng/ml), basic fibroblast growth factor(bFGF,25 ng/ml) addexamethasone (DEX,10-7mol/L) with 15%FBS in DMEM. Cartilage slices wereobtained from femoral condyles and patellar grove in the same rabbit. The minced cartilage was digested in Ⅱ collagenase (3 mg/ml) to obtain chondrocytes(Group D). The change of cell appearance, proliferation capacity, glycosaminoglycans(GAG), immunohistochemical staining for type Ⅰ, Ⅱ collagen were observed during the 5th passage MSCs and MSCs after induction or gene modification. Expression of mRNA for type Ⅰ and Ⅱ collagen was detected by RT-PCR. Results Primary MSCs proliferated as shortspindle shape, while the 5th MSCs showed longspindle shape. Positive stain of type Ⅰ collagen could be found in groups A, B and C, while positivestain of type Ⅱ collagen was shown in groups B and D. The content of GAG in group B was higher than that in group A, but there was no significant difference between them(Pgt;0.05), and there was significant difference between groups A and D(Plt;0.05). No significant difference was noted in groups A,B and C on proliferation by MTT(Pgt;0.05),except that of at the fourth day after transfection between groups A and C(Plt;0.05). RT-PCR demonstrated that MSCs always had higher levelsof mRNA type Ⅰ collagen in groups A, B and C. The expression of mRNA type Ⅱ collagen was identified in groups B and D, and only low levels of mRNA type Ⅱ collagen in group C. Conclusion The above results indicate MSCs have a natural tendency of osteogenic differentiation in vitro culture, and also demonstrate the chondrogenic potency with the technique of cytokines induction or gene modification after passage. MSCs can be transfected efficiently being seed cells in tissue engineered bone or cartilage to accept target genes such as adHGF, and have a higher levels of expression in vitro, which lasted 4 weeks at least.

    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. ResultsA 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.

  • Relation between residence and surgical characteristics of patients with colorectal cancer: a real-world study based on DACCA

    ObjectiveTo analyze the impact of the residence of patients with colorectal cancer (CRC) on surgical characteristics in the current version Database from Colorectal Cancer (DACCA). MethodsAccording to the established screening conditions, the patients with CRC were collected from the updated version of DACCA on January 23, 2023. The analysis indicators enrolled in this study included: the grouping indicator was residence, the surgical characteristic indicators included the surgical timing, surgical nature, expanded resection, intersphincteric resection (ISR) type, patient’s willingness of preserving the anus, and whether preserving the anus. The patients were categorized into three groups based on the residence: inside Chengdu City, outside Chengdu City within Sichuan Province, and outside Sichuan Province. The surgical characteristic indicators of patients with CRC from different residences were comparatively analyzed. ResultsA total of 6 832 analyzable data rows were enrolled. The results of statistical analysis revealed the following findings: there were no statistical differences in the surgery timing and surgery nature among the patients with colon cancer or rectal cancer from the different residences (Surgery timing: H=1.665, P=0.435; H=4.153, P=0.125. Surgery nature: χ2=1.586, P=0.453; χ2=0.990, P=0.610); For the patients with rectal cancer from the different residences, the distributions of the ISR type (H=0.514, P=0.773), patients’ willingness of preserving the anus (χ2=1.437, P=0.487), and whether preserving the anus (χ2=5.513, P=0.064) had no statistical differences. In addition, although there was no statistical difference in the distribution of expanded resection or not among the patients with rectal cancer in different residences (χ2=2.363, P=0.307), it was found that there was statistical difference in the distribution of enlarged resection or not among the patients with colon cancer in different residences (χ2=17.324, P<0.001). ConclusionsFrom the data analysis in DACCA, there are not statistical differences in surgical characteristic indicators such as surgical timing, surgical nature, ISR type, patients’ willingness of preserving the anus, and whether preserving the anus among patients with colon or rectal cancer from different residences. However, the proportion of underwent expanded surgery in the colon cancer patients who from outside Sichuan Province as compared with inside Sichuan Province is relatively higher, this suggests that surgical difficulty is more difficult for the patients from outside Sichuan Province.

  • Relationship between the residence and oncological characteristics of colorectal cancer patients: A real-world study based on DACCA

    Objective To analyze the relationship between the residence and oncological characteristics of colorectal patients served by Sichuan University West China Hospital as a regional center in the current version of the Database from Colorectal Cancer (DACCA). Methods The DACCA version selected for this data analysis was the updated version on January 5, 2022. The data items analyzed included: residence, precancerous lesions, family history of cancer, tumor location, tumor morphology, tumor orientation, tumor pathology, tumor differentiation and preoperative TNM staging. According to the regional distribution of colorectal cancer patients' residence in the database, they were divided into Sichuan group and non-Sichuan group, and the Sichuan group was further divided into Sichuan-Chengdu group and Sichuan-non-Chengdu group. Results The DACCA database was filtered by conditions to obtain 7 232 valid data. ① The composition ratio of precancerous lesions in different places of residence: The difference between the Sichuan group and the non-Sichuan group was statistically significant (χ2=14.462, P=0.003), and the difference between the Sichuan-Chengdu group and the Sichuan-non-Chengdu group was not statistically significant (χ2=7.591, P=0.101). ② Composition ratio of family history of cancer in different places of residence: In the family history of cancer in oneself, the difference between Sichuan group and non-Sichuan group as well as between Sichuan-Chengdu group and Sichuan-non-Chengdu group were not statistically significant (χ2=1.121, P=0.606; χ2=1.047, P=0.621). In the family history of cancer in relatives, the differences in the composition ratio of different tumor histories between the Sichuan group and the non-Sichuan group, and between the Sichuan-Chengdu group and the Sichuan-non-Chengdu group were not statistically significant (χ2=0.813, P=0.692; χ2=2.696, P=0.262). ③ Tumor site composition ratios in different places of residence: The difference between Sichuan group and non-Sichuan group was not statistically significant (χ2=0.476, P=0.490), and the difference between Sichuan-Chengdu group and Sichuan-non-Chengdu group was statistically significant (χ2=36.216, P<0.001). ④ Tumor morphology composition ratio in different places of residence: The difference between Sichuan group and non-Sichuan group was statistically significant (χ2=19.560, P<0.001), and the difference between Sichuan-Chengdu group and Sichuan-non-Chengdu group was not statistically significant (χ2=5.377, P=0.247). ⑤ Composition ratio of tumor orientation in different places of residence: The differences in composition ratio of tumor orientation between Sichuan group and non-Sichuan group and between Sichuan-Chengdu group and Sichuan-non-Chengdu group were statistically significant (χ2=17.484, P=0.005; χ2=26.820, P<0.001). ⑥ Composition ratio of tumor pathological properties under different residence: The differences in the comparison of pathological properties between Sichuan group and non-Sichuan group as well as between Sichuan-Chengdu group and Sichuan-non-Chengdu group of CRC patients were not statistically significant (χ2=8.136, P=0.408; χ2=7.278, P=0.506). ⑦ Composition ratio of tumor differentiation degree under different residence groupings: the differences in the composition ratio of tumors with different degrees of differentiation were not statistically significant between Sichuan group and non-Sichuan group, and between Sichuan-Chengdu group and Sichuan-non-Chengdu group (H=0.289, P=0.591; H=0.156, P=0.693). ⑧ The composition ratio of TNM staging of tumors before operation in different places of residence: between the Sichuan group and the non-Sichuan group, the difference in the composition ratio of preoperative TNM staging of CRC patients was statistically significant (H=8.023, P=0.005); between the Sichuan-Chengdu group and the Sichuan-non-Chengdu group, the difference in the composition ratio of preoperative TNM staging of CRC patients was not statistically significant (H=0.218, P=0.640). Conclusions Data analysis in DACCA reveal multiple associations between the place of residence and oncological characteristics of CRC patients. There are differences in the composition of the types of precancerous lesions among CRC patients in different places of residence. The proportion of CRC is higher in the family history of cancer. In terms of the site of tumor occurrence, the proportion of tumors located in the rectum is higher than that in the colon. In the composition of tumor morphology in all regions, the ulcerative type is the most frequent. The composition of tumor orientation is different in patients with CRC, and those who has involved a circle of the intestinal wall are the most frequent. Most CRC patients are already in middle or late stage when the tumor is discovered, and the proportion of middle or late stage patients in non-Sichuan provinces was even higher.

  • Clinical characteristics and prognosis of resectable esophageal small cell carcinoma after surgical resection

    ObjectiveTo investigate the clinical characteristics and prognosis of resectable esophageal small cell carcinoma after surgical resection.MethodsA retrospective study of patients with resectable esophageal small cell carcinoma undergoing surgical resection from January 2009 to June 2015 in the Department of Thoracic Surgery, Sichuan Provincial Fourth People's Hospital and Department of Thoracic Surgery, West China Hospital of Sichuan University was performed. Survival analysis was conducted by Kaplan-Meier analysis and log-rank test. Cox regression model was used for identifying independent prognostic factors.ResultsA total of 53 patients with resectable esophageal small cell carcinoma were included for analysis. The mean age was 58.4 ± 8.3 years and there were 42 male patients and 11 female patients. Forty-two patients were diagnosed as pure esophageal small cell carcinoma while 11 patients were diagnosed with mixed esophageal small cell carcinoma, who were all mixed with squamous cell carcinoma. Most of the esophageal small cell carcinomas were located in the middle (58.5%) and lower (32.1%) segments of the esophagus. Thirty patients (56.6%) were found to have lymph node metastasis, and 7 patients (13.2%) were found to have lymphovascular invasion. According to the 2009 TNM staging criteria for esophageal squamous cell carcinoma, there were 12 patients with stage Ⅰ disease, 19 patients with stage Ⅱ disease, and 22 patients with stage Ⅲ disease. Most of the patients underwent left thoracotomy with two-field lymphadenectomy. Postoperatively, only twenty-two patients (41.5%) received adjuvant chemoradiotherapy. The median survival time of these patients was 20.1 months, and the 1- and 3-year survival rate was 75.5% and 33.1%, respectively. For prognosis, age, gender, pathological type, tumor location, and lymphovascular invasion had no significant impact on long-term survival of these patients. However, TNM stage (1 year survival rate: stage Ⅰ: 91.7%; stage Ⅱ: 78.9%; stage Ⅲ: 63.6%; P=0.004) and postoperative adjuvant therapy (1 year survival rate: 81.8% vs. 71.0%; P=0.005) had significant impact on the survival of patients with esophageal small cell carcinoma. In multivariate analysis, TNM stage and postoperative adjuvant therapy were independent prognostic factors for long-term prognosis of patients with esophageal small cell carcinoma.ConclusionEsophageal small cell carcinoma is very rare, with high malignancy and poor prognosis. For patients with resectable esophageal small cell carcinoma, the TNM staging system of esophageal squamous cell carcinoma can be used to direct the choice of treatment options. For early stage esophageal small cell carcinoma (stage Ⅰ/Ⅱ), surgery plus postoperative adjuvant chemoradiotherapy can be the prior therapeutic choice, while for locally advanced esophageal small cell carcinoma (stage Ⅲ), chemoradiotherapy should be the preferred treatment.
