Objective·To explore the diagnostic and treatment methods for patients with cystic fibrosis(CF)complicated by allergic bronchopulmonary aspergillosis(ABPA),and to enhance clinicians'understanding of these two diseases.Methods·A retrospectively analysis was conducted on the clinical data of 5 patients with CF complicated by ABPA admitted to the Department of Respiratory Medicine,Shanghai Children's Hospital,Shanghai Jiao Tong University School of Medicine,from July 2023 to August 2024.A literature search was performed in PubMed,Web of Science,Cochrane Library,and CNKI for studies published in the past 10 years regarding the co-existence of these diseases.Clinical manifestations,treatment courses,and current epidemiological research were summarized and analyzed.Results·Common symptoms of patients with CF complicated by ABPA included aggravated cough and expectoration,wheezing,fever,and dyspnea.Whole-exome aequencing indicated mutations in the cystic fibrosis transmembrane conductance regulator(CFTR)gene,and an increase in the concentration of chloride ions in sweat.The levels of total serum immunoglobulin E(IgE)and Aspergillus fumigatus-specific IgE increased,and chest computed tomography(CT)showed bronchiectasis and mucus plugging.CF complicated by ABPA is often missed or misdiagnosed for asthma.In China,ABPA is often diagnosed before CF,whereas in Caucasian populations CF is typically diagnosed first.Initial treatment usually involves long-term oral administration of antifungal drugs such as voriconazole combined with glucocorticoids such as prednisone.For patients with frequent relapses or severe side effects,alternative antifungal agents or omalizumab therapy may be considered.Co-infection with Pseudomonas aeruginosa is common,often requiring intravenous antibiotics such as cefoperazone-sulbactam.Current epidemiological research focuses mainly on clinical characteristics,treatment regimens,and novel diagnostic methods.Conclusion·ABPA and CF have overlapping symptoms.Accurate diagnosis of CF complicated by ABPA requires genetic testing,sweat chloride measurement,chest CT,and serological tests.The coexistence of these diseases often leads to missed,delayed,or incorrect diagnosis,increasing patient burden.Present epidemiological studies mainly address clinical characteristics with a lack of targeted clinical drug trials for this patient population.

Objective:The result of influenza etiology surveillance in Chuxiong prefecture were analyzed to master the epidemic characteristics of influenza virus and provide scientific basis for influenza prevention and control.Methods:Real-time PCR assay and MDCK cell culture method were used to detect and separate influenza virus nucleic acids from influenza-like cases (ILI) and suspected influenza cases from 2017 to 2022 come from the sentinel hospitals.Results:From 2017 to 2022, a total of 7 302 cases of ILI and 1 079 cases were detected positive, with a positive rate of 14.78%. The positive rate in the six years was 14.71%、15.44%、20.11%、5.04%、10.90% and 21.08%, and the positive rate in 2020 was the lowest. Among them, the positive rate of influenza A was higher than that of influenza B, and higher in spring and winter than in summer and autumn., One H9N2 human infected with avian influenza virus was detected positive.The outbreak cases were mainly influenza B, followed by influenza A H3N2, and students were susceptible to it. The proportion of influenza-like cases in the 0~5 year old group was the highest (64.16%), and the protortion in 60~year old group was the lowest (0.05%).Conclusions:From 2017 to 2022, influenza A was predominant in Chuxiong prefecture, with high prevalence in winter and spring. The influenza strains presented diversity and each strain circulated alternately. The implementation of COVID-19 prevention and control measures can effectively reduce the infection rate of influenza virus .In addition, there are human cases of avian influenza infection in Chuxiong prefecture. So the surveillance of influenza-like cases should be strengthened an improved, and to expand the monitoring of human and avian influenza.

Objective To investigate the expression of CK2α' in hepatocellular carcinoma (HCC) tissues and its prognosis value. Methods Tissue microarray was made from tumor and adjacent normal tissues of 83 patients with HCC. Immunohistochemical was used to stain the microarray for semi-quantitative analysis, and the expression of CK2α' in HCC tissues and adjacent normal tissues was compared. The associations between CK2α' expression and clinicopathologic features of HCC patients were analyzed with χ² text. The prognostic value of CK2α' was estimated using Kaplan-Meier approach. Results The average positive expression rate of CK2α' was 47.8% in HCC and 65.4% in adjacent normal tissues. The positive expression rate of CK2α' in HCC tissues was lower than that in adjacent normal tissues (P < 0.01). The expression level of CK2α' in the cancer tissues of 74.7% cases was significantly lower than that in the adjacent tissues. HCC patients with low CK2α' expression had higher risk of recurrence and shorter overall survival time (P < 0.05). The expression of CK2α' was significantly correlated with CK19 (P < 0.05). Conclusion CK2α' is down-regulated in HCC tissues and correlated with the prognosis of patients. It could be a potential prognostic marker for HCC.

Objective To investigate the expression level of calcitonin gene-related peptide-receptor component protein (CRCP) in hepatocellular carcinoma (HCC) tissue and adjacent tissue and its association with the clinicopathological features and prognosis of patients. Methods HCC and adjacent tissue samples were collected from 79 HCC patients who underwent surgical resection in Eastern Hepatobiliary Surgery Hospital, Navy Medical University, from June 2003 to September 2009. Tissue microarray was prepared, and immunohistochemistry was used for quantitative analysis. Related proteins were extracted and measured by Western blot, and the expression of CRCP was compared between HCC tissue and adjacent tissue. The chi-square test was used for comparison of categorical data between groups. The receiver operating characteristic (ROC) curve analysis was performed to obtain the area under the ROC curve (AUC), and goodness of fit was evaluated. Youden index was used to determine the optimal cut-off value. and the Kaplan-Meier survival analysis was used to analyze the association of CRCP expression with the recurrence and prognosis of HCC, and the log rank test was used for comparison between the two groups. Results Among the 79 HCC patients, there were 67 male patients and 12 female patients, with an age of 10-72 years, and 20 patients had portal vein tumor thrombus. As for pathological grade, 1 had grade 4 HCC, 61 had grade 3 HCC, and 17 had grade 2 HCC; as for BCLC stage, 5 had BCLC stage 0 HCC, 55 had BCLC stage A HCC, 11 had BCLC stage B HCC, and 8 had BCLC stage C HCC. Western blot showed that the expression level of CRCP in HCC tissue was lower than that in adjacent tissue in 4 patients, and immunohistochemistry showed that the expression level of CRCP in HCC tissue was significantly lower than that in adjacent tissue in 75.9% of the patients. Low CRCP expression was associated with CK19 positivity, incomplete tumor capsule, presence of portal vein tumor thrombus, and high pathological grade ( χ 2 =6.410, 4.829, 9.319, and 9.083, all P < 0.05). Compared with the low CRCP expression group, the high CRCP expression group had a significantly longer overall survival time and a significantly lower recurrence rate ( P < 0.001 and P =0.009). Conclusion Patients with low CRCP expression in HCC tissue tend to have a poorer prognosis than those with high CRCP expression, and CRCP may participate in the development, progression, and metastasis of HCC, suggesting that this molecule can be used as a potential biomarker to predict the prognosis of HCC patients.
