Chinese Journal of Clinical Oncology 2009;36(24):1394-1397
Objective: To study the influence of clinicopathologic factors on the recurrent pattern of colorectal cancer after radical treatment. Methods: There were 464 consecutive patients with colorectal cancer treated with radical surgery between January 1998 and December 2002 in our hospital. The clinicopathologic features of 90 patients with relapse of colorectal cancer after radical surgery were analyzed. According to the interval between radical surgery and recurrence, these 90 patients were divided into subgroups, the early recurrent group (within 30 months after surgery) and the late recurrent group (more than 30 months after surgery). Chi-square test was used for univariate analysis, and the Logistic regression model was performed for multivariate analysis. Result: There were 78 (86%) patients in the early recurrent group and 12 (14%) patients in the late recurrent group. The median time of recurrence was 17.4 months. The median recurrent time in stage I patients was 35.1 months, 13.6 months in stage II patients, and 12.9 months in stage III patients, respectively. Univariate analysis showed that the depth of penetration, the number of positive lymph nodes, and the gross appearance of tumor were predictors for early recurrence. Multivariate analysis revealed that the depth of penetration (T category) of the primary tumor significantly predicted for early recurrence (P= 0.049). Conclusion: A great proportion of recurrence in patients with colorectal cancer occurred within 30 months after radical treatment, but the late recurrence which occurs at more than 30 months after radical surgery should not be neglected. Patients with different patterns of recurrence had different intervals between radical surgery and recurrence. DM (distant metastasis) occurs earlier than LR (local recurrence). The depth of penetration of the primary tumor is an independent predictor for early recurrence of colorectal cancer patients after radical surgery.

Impaired clearance of apoptotic cells is important in the pathogenesis of autoimmune disease.C-reactive protein (CRP) is an acute phase protein that plays a major role in the regulation of the autoimmune and inflammatory response .CRP has a role in the clearance of bacteria and dying and altered cells through binding to phosphocholine and might also have more complex immunomodulatory functions . CRP function as opsonins for pathogens and dying and apoptotic cells through activation of the complement pathway and through binding to Fcγreceptors , and is associated with the clearance of apoptotic cells and nuclear antigen , thus becoming a protective molecule against pathogenic autoimmune responses in general . Measurement of serum CRP level is in widespread clinical use as a sensitive marker of inflammation and autoimmune disease , particularly in relation to the use of the CRP-based disease activity score in the evaluation of rheumatoid disease.

Objective :
To investigate the epidemiological and clinical characteristics of cases with pertussis in Yiwu City, Zhejiang Province, so as to provide insights into pertussis diagnosis and control.
Methods:
A total of 186 patients with definitive diagnosis of pertussis in medical institutions in Yiwu City from November 1, 2020 to August 31, 2022 were recruited, and subjects' demographic, clinical symptoms and history of pertussis vaccination were collected using questionnaire surveys. The temporal, population, and spatial distribution and clinical symptoms of pertussis were analyzed using a descriptive epidemiological method, and the clinical characteristics of pertussis patients with different doses of pertussis vaccination were compared.
Results:
Pertussis was found to predominantly occur during the period between July and November (101 cases, 54.30%), and the three highest-incidence regions included Jiangdong Street, Beiyuan Street and Choujiang Street (87 cases, 46.77%). The 186 pertussis cases included 105 males (56.45%) and 81 females (43.55%), and included 144 cases with age of onset under 7 year (77.42%). Preschool and diaspora children were predominant among all pertussis cases, and the main clinical symptoms included spasmodic cough (97 cases, 52.15%), post-tussive vomiting (82 cases, 44.09%) and aggravated cough at night (77 cases, 41.40%). Routine blood tests measured 119 cases with abnormal white blood cell counts (63.98%), 137 cases with abnormal lymphocyte counts (73.66%), 39 cases with abnormal neutrophil counts (20.97%), 21 cases with abnormal platelet counts (11.29%) and 111 cases with abnormal hemoglobin concentrations (59.68%). There were 55 cases that were unvaccinated (29.57%), 23 cases that were not fully vaccinated (12.37%), and 108 cases that were fully vaccinated (58.06%). There were significant differences among pertussis cases with different doses of vaccination in terms of age, incidence of post-tussive vomiting, percentage of abnormal platelet counts and percentage of hemoglobin concentrations (all P<0.05).
Conclusions
The majority of pertussis cases are preschool and diaspora children in Yiwu City from November 1, 2020 to August 31, 2022, and the clinical symptoms mainly include spasmodic cough, post-tussive vomiting and aggravated cough at night, with atypical symptoms. The capability for differential diagnosis of pertussis is required to be improved in medical institutions.

Objective To investigate the effects of erythropoietin (EPO) on complement 3a (C3a)-induced renal tubular epithelial to mesenchymal transition. Methods The HK-2 cells were divided into 6 groups namely control group,EPO group,TGF-β group,TGF-β+EPO group,C3a group and EPO+C3a group.The mRNA and protein expressions of α-SMA,E-cadherin and C3 were investigated by RT-PCR,Western blot and immunofluorescence respectively. Results Compared with control group and EPO group,the mRNA and protein expressions of α-SMA in HK-2 cells were up-regulated after the intervention of C3a or TGF-β (all P<0.05).On the contrast,the mRNA and protein expressions of E-cadherin were down-regulated(P<0.05),the mRNA and protein expressions of C3 were enhanced (all P<0.05).However,all those above effects of C3a or TGF-β were inhibited after the intervention of EPO (all P<0.05). Conclusion EPO is capable of suppressing the epithelial to mesenchymal transition induced by C3a.
