【Abstract】Objective To investigate the recent studies on the biocharacters of keratin family (e.g. genetic mutations and abnormal expressions) and their relationships with the malignant tumors. Methods The literatures of recent years on the biocharacters of keratin family (e.g. genetic mutations and abnormal expressions) and their relationships with the malignant tumors were reviewed. Results Keratin family is a kind of structural proteins in cell which plays an important role in cytomechanics and regulates cell-cycle. The mutations of keratin genes (mRNA) or the overexpression of keratin proteins would interfere with the order of cell-cycle or the integrity of cytomechanics, and lead to some diseases and malignant tumors finally. Conclusion The studies on biocharaters of keratin family (e.g. genetic mutations and abnormal expressions) are helpful in the diagnosis, staging and the evaluation of prognosis of some diseases and cancers, e.g. liver cirrhosis, breast cancer, rectum carcinoma, etc.
Objective To study the etiology， pathogenesis， and diagnosis of small bowel volvulus in adults. Method The clinical data of 43 cases of small bowel volvulus admitted to HassanⅡHospital of Settat from October 2009 to October 2012 were analyzed retrospectively. Results There were 11 cases of spontaneous small bowel volvulus.There were 32 cases of secondary small bowel volvulus， of which 19 cases due to postoperative abdominal adhesions. Clinical manifestation：early persistent severe abdominal pain was in 40 cases， frequent vomiting was in 29 cases， intestinalpattern or abdominal mass was in 28 cases. All 43 patients were received surgery， 22 （51.2%） cases were diagnosed by preoperative ultrasonography， small bowel necrosis was found in 16 cases during operation， 37 （86.0%） patients were cured and 6 （14.0%） patients died. Conclusions Secondary small bowel volvulus is main small bowel volvulus， post-operative abdominal adhesion is major causes of small bowel volvulus， the value of abdominal X-ray in diagnosing is limited. However， ultrasonography and CT are helpful in diagnosing these diseases. Small bowel volvulus and intestinal obstruction can reinforce each other. Early small bowel volvulus is characterized by clinical conditions such as severe abdominal pain， early vomiting signs， and signs not matching the symptoms. Acute onset and rapid progression are the features of small bowel volvulus， surgery should be intervened in early stage.
Objective To investigate the relationship between delayed diagnosis time (time from symptom onset to diagnosis) in patients with chronic obstructive pulmonary disease (COPD) and the burden of type 2 inflammation (defined as the persistent inflammatory status assessed by blood EOS counts, EOS%, and Fractional exhaled nitric oxide(FeNO) among other biomarkers).MethodsThis study was a single-center, observational study that included patients with COPD first diagnosis at the respiratory outpatient department of our hospital from June 2023 to December 2024. Asthma-COPD overlap (ACO) were identified according to the 2017 Spanish COPD guidelines. Clinical data were collected, including gender, age, delayed diagnosis time, acute exacerbations in the past year, pulmonary function tests, exhaled nitric oxide (FeNO), and type 2 inflammatory markers such as blood eosinophil counts (EOS). The correlation between the delayed diagnosis time and type 2 inflammation burden, as well as its influencing factors, were analyzed. Results A total of 195 patients were included, with 98 cases of COPD and 97 cases of ACO. The mean delayed diagnosis time was 18.0 (2.8, 37.5) months for the overall patients, 24.0 (1.0, 60.0) months for COPD, and 16.5 (3.0, 36.0) months for ACO, with no significant difference between the COPD and ACO groups (P>0.05). The median blood EOS counts, EOS%, andFeNO levels were 180 cells/μL, 1.9%, and 18 ppb in the COPD group, respectively, compared to 350 cells/μL, 4.7%, and 28 ppb in the ACO group, indicating higher type 2 inflammation levels in the ACO group (all P<0.001). A significant correlations were found between the disease course and the blood EOS counts and EOS% of the patients (respectively r=0.159, 0.152, all P<0.05).FeNO levels showed no significant correlation with delayed diagnosis time of COPD (P>0.05). Patients with a history of asthma and acute exacerbations in the past year had longer delayed diagnosis time and higher peripheral blood eosinophil counts (all P<0.05). Binary logistic regression analysis revealed that BMI and delayed diagnosis time were independent influencing factors for blood EOS counts (all P<0.05). ConclusionDelayed diagnosis of COPD was associated with aggravated type 2 inflammatory burden. Clinical practice should emphasize early recognition of COPD symptoms and implement prompt therapeutic interventions.
Objective To explore the methods of early diagnosis of arteriosclerosis obliterans of lower extremity (ASOLE). Methods The related literatures on ASOLE detection means adopted clinically were reviewed, and their advantages and disadvantages were compared.Results Asymptomatic ASOLE could be discovered by determination of ankle brachial index (ABI) and toe brachial index (TBI), which was a good index for arterial function assessment of lower extremity. Pulse wave velocity (PWV) was more vulnerable and less sensitive than ABI, and therefore more suitable for screening of a large sample. ASI was an index to assess arterial structure and function, and it had a good correlation with PWV. Flow-mediated dilation (FMD) was a measurement evaluating the function of endothelial cell; Pulse wave measurement was simple, sensitive, and its result was reliable. Color Doppler ultrasonography could localizate the lesion and determine the degree of stenosis at the same time. Multiple-slice CT angiography (MSCTA) was more accurate than color Doppler ultrasonography, but its inherent shortcomings, such as nephrotoxicity of contrast agent, was still need to be resolved. 3D-contrast enhancement magnetic resonance angiography (CEMRA) had little nephrotoxicity, but a combination of other imaging methods was necessary. Microcirculation detections required high consistency of the measurement environment, but they were simple, sensitive and noninvasive, and therefore could be used for screening of ASO. Conclusion Publicity and education of highrisk groups, and reasonable selection of all kinds of detection means, are helpful to improve the early diagnosis of ASOLE.
