Objective To investigate the clinical features and effective treatment of patients with severe type A H1N1 flu in Wenzhou. Methods The clinical data of 42 hospitalized patients with severe type A H1N1 flu were analyzed and the clinical features were summarized. Results A total of 42 patients with severe type A H1N1 flu all began with fever and cough. The symptoms of expectoration, pharyngalgia, chilly accounted for 92. 9%, 90. 5% and 42. 9%, respectively. The peripheral leucocyte counts were normal or reduced. C-reactive protein and erythrocyte sedimentation rate levels both increased in 30 patients (71.4%). About 95.2% (40/42) patients had changes of pulmonary imaging. All of the patients were treated with oseltamivir and effective antibiotic drugs as well as symptomatic management. No patients was treated with glucocorticoid. The patients with underlying diseases were given proper treatment. Three cases were treated with antifungal therapy and 3 pregnant patients were timely terminated of pregnancy. Conclusions Severe type A H1N1 flu progresses rapidly and the lower respiratory tract is involved soon after onset. Therefore, the patient should be diagnosed early and treated promptly after presenting fever, which will lead to good prognosis.

Fatigue, which is one of the most commonly reported symptoms in cancer, can negatively impact the functional status and the health-related quality of life of individuals. Although awareness and
study of CRF have grown in recent years,the biological mechanisms and risk factors that induce CRF remain unclear.This paper systematically reviews the available evidence on the biological mechanisms and the risk factors to guide the development of targeted, individualized interventions for cancer-related fatigue.

Objective To assess the value of four different techniques of detecting the Mycobacterium tuberculosis (MTB) in bronchoalveolar lavage fluid (BALF) in the diagnosis of tracheobronchial tuberculosis. Methods A total of 98 patients diagnosed as tracheobronchial tuberculosis were selected from May 1,2013 to June 30,2016. The clinical data was analyzed retrospectively,and the positive rates of MTB of the 960 cultrue, the direct smears , the modified Ziehl?Neelsen stain method and Xpert MTB/RIF assay were compared. Results The positive rates of the 960 cultrue,the direct smears,the modified Ziehl?Neelsen stain method and Xpert MTB/RIF assay were 20.4%(20/98),15.3%(15/98),70.4%(69/98) and 74.5%(73/98),respectively. Among the four techniques ,the positive rates of the modified Ziehl?Neelsen stain method and Xpert MTB/RIF assay were significantly higher than those of the 960 cultrue and the direct smears(P<0.05,respectively). However,no significant difference was found between the modified Ziehl?Neelsen stain method and the Xpert MTB/RIF assay (P > 0.05). Conclusions The modified Ziehl?Neelsen stain method and Xpert MTB/RIF assay for detecting the MTB in BALF have high clinical value in the diagnosis of tracheobronchial tuberculosis.

Objective:To investigate the value of qualitative characteristics of contrast-enhanced ultrasound (CEUS) and VueBox quantitative parameters in the evaluation of pathological molecular typing of breast cancer.Methods:A retrospective analysis was performed on 133 patients with pathologically confirmed breast cancer who underwent CEUS examination in the People′s Hospital of Guangxi Zhuang Autonomous Region from January 2020 to July 2022. The patients were divided into Luminal A type, Luminal B type, human epidermal growth factor receptor-2(HER-2) type and triple negative type according to the results of immunohistochemistry. The differences of qualitative characteristics and quantitative parameters of CEUS in different molecular subtypes of breast cancer were analyzed. The ROC curve was used to evaluate the diagnostic efficacy of CEUS in the differentiation of molecular subtypes of breast cancer.Results:There were significant differences in enhancement intensity, post-enhancement boundary, filling defect and peripheral radial convergence among different molecular subtypes of breast cancer(all P<0.05), while there was no significant difference in enhancement uniformity ( P>0.05). Peak enhancement (PE), wash-in and wash-out areas under the curve (WiWoAUC), and wash-in ratio (WiR) of HER-2 type and triple-negative type breast cancer were higher than Luminal A type and Luminal B type (all P<0.05). ROC curve analysis showed that PE and radial convergence had reasonable diagnostic efficiency in Luminal A type, and the areas under the curve were 0.849 and 0.780, sensitivity was 0.711 and 0.889, specificity was 0.909 and 0.671, accuracy was 0.842 and 0.744, respectively. The areas under the curve of PE in diagnosing Luminal B type was 0.852, the sensitivity, specificity, and accuracy were 0.825, 0.763 and 0.782, respectively. The area under the curve of WiWoAUC and filling defect in diagnosing HER-2 type were 0.912 and 0.898, the sensitivity was 0.903 and 0.903, the specificity was 0.853 and 0.892, and the accuracy was 0.865 and 0.895, respectively. The area under the curve of clear boundary after enhancement in diagnosing triple negative type was 0.919, and the sensitivity, specificity and accuracy were 0.941, 0.897 and 0.902, respectively. Conclusions:There are differences in the qualitative characteristics and quantitative parameters of contrast-enhanced ultrasound in different molecular types of breast cancer. CEUS is suggested as a noninvasive modality for preoperative prediction of molecular subtypes of breast cancer.

Objective:To evaluate the value of VueBox ? contrast-enhanced ultrasound (CEUS) quantitative analysis combined with ACR TI-RADS classification in the diagnosis of benign and malignant solid thyroid nodules. Methods:A total of 201 patients with thyroid solid nodules (201 nodules) who underwent surgery or puncture biopsy in the People′s Hospital of Guangxi Zhuang Autonomous Region were enrolled from October 2020 to February 2022. The preoperative conventional ultrasound and contrast-enhanced ultrasound images were retrospectively analyzed. According to the pathological results, they were divided into the malignant group and benign group. The differences of the quantitative parameters of CEUS between the two groups were analyzed, including peak enhancement (PE), wash-in and wash-out area under the curve (WiWoAUC), wash-in perfusion index (WiPI). ΔPE, ΔWiWoAUC, ΔWiPI were obtained by calculating the parameter difference between the surrounding normal glands and nodules. ROC curve was used to analyze the value of different quantitative parameters in the differential diagnosis of benign and malignant solid thyroid nodules. The CEUS quantitative parameters with best diagnostic performance was selected and combined with ACR TI-RADS classification system to evaluate the diagnostic efficiency of the single diagnostic approaches and the combined approach.Results:The quantitative parameters of PE, WiWoAUC, WiPI, ΔPE, ΔWiWoAUC, ΔWiPI were significantly different between benign group and malignant group (all P<0.001). ΔPE had the highest diagnostic value among all the quantitative parameters (the area under the ROC curve was 0.802), and the cut-off value was 0.21.ΔPE combined with ACR TI-RADS classification showed the best efficiency in diagnosis of benign and malignant thyroid nodules, with an area under the curve of 0.898, and the sensitivity, specificity, positive predictive value and negative predictive value of 73.39%, 93.48%, 93.02% and 74.78%, respectively. Conclusions:Quantitative parameters of CEUS by using VueBox ? software is valuable for the differential diagnosis of benign and malignant solid thyroid nodules, and its combination with ACR TI-RADS classification can improve the diagnosis accuracy.

Objective To construct a nomogram prediction model for major adverse cardiovascular events(MACE)within 1 year after percutaneous coronary intervention(PCI)in elderly patients with acute coronary syndrome(ACS).Methods A retrospective analysis was conducted on 551 patients with diagnosed ACS and undergoing PCI in Department of Cardiovascular Medicine of Air Force Medical Center from 1 January 2020 to 1 April 2022.According to the occurrence of MACE during 1 year of follow-up,they were classified into MACE group(n=176)and non-MACE group(n=375).Risk factors for the occurrence of MACE in elderly ACS patients within 1 year after PCI were analysed using univariate and multivariate logistic regression,a nomogram prediction model was constructed,and the predictive power of the model was assessed using the area under the ROC curve(AUC).Results The MACE group had significantly higher Gensini score,systemic immune-inflammation index,and GRACE score,but obviously lower prognostic nutritional index than the non-MACE group(P＜0.01).Multivariate logistic regression analysis showed that recent smoking(OR=2.222,95％CI:1.361-3.628,P=0.010),hyperlipidaemia(OR=1.881,95％CI:1.145-3.089,P=0.013),prognostic nutritional index(OR=4.645,95％CI:2.788-7.739,P=0.001),LVEF(OR=5.177,95％CI:3.160-8.483,P=0.001),systemic immune-inflammation index(OR=5.396,95％CI:3.179-9.159,P=0.001),and preoperative di-agnosis of non-STEMI(OR=2.829,95％CI:1.356-5.901,P=0.006)or STEMI(OR=3.451,95％CI:1.596-7.463,P=0.002)were independent influencing factors for occurrence of MACE after PCI in elderly ACS patients.ROC curve analysis showed that the AUC value of the nomo-gram model for predicting MACE within 1 year after PCI in elderly ACS patients was 0.888.Con-clusion Our developed nomogram model is simple and practical,and can effectively predict the occurrence of MACE within 1 year after PCI in elderly ACS patients.And external validation should be carried out to ensure its generality.
