Objective To evaluate the clinical significance of CT + MRI scans in diagnosis of primary liver cancer and prognosis evaluation after interventional therapy. Methods A total of 150 cases of patients with primary liver cancer admitted to our hospital from January 2019 to January 2021 were selected. They all received interventional treatment, and were examined by CT and MRI. The results of pathological examination were taken as the gold standard in this study to compare the diagnostic efficacy of CT, MRI and CT+MRI.Kappa value was used to compare the consistency of CT, MRI, CT+MRI scans with gold standard, and compared the detection rate of lesions after CT, MRI and CT+MRI interventional surgery. Results The diagnostic accuracy (98.67%), specificity (75.00%) and sensitivity (99.32%) of CT + MRI scans were higher than those of CT (86.00%, 25.00%, 87.67%) and MRI scans (90.67%, 91.78%, 50.00%),P<0.05 (which differences were statistically significant). The consistency of CT + MRI scans with gold standard was good (kappa value was 0.779), but the consistency of CT/MRI scans with gold standard were not satisfying (kappa value were 0.527, 0.596). The total detection rate of lesions after CT + MRI interventional surgery (12.00%) was higher than that of CT (2.00%) and MRI (4.00%, which P<0.05). Conclusion CT + MRI scans can improve the detection rate of lesions in patients with primary liver cancer after interventional therapy, and make up for the deficiency of only CT or MRI scans.

Methods From January 20, 2020 to February 29, 2020, a retrospective analysis was carried out on 129 suspected cases of 2019-nCoV infection admitted to the isolation ward of the only medical unit designated for children in Guangzhou. The epidemiology, disease characteristics, clinical characteristics, laboratory examination, outcome and follow-up were summarized and analyzed. Results There were 79 males and 50 females, with a minimum age of 1 month and a maximum age of 13 years. Anong them, 51 cases (39.5%) had a history of tourism or residence in the epidemic area of Wuhan, 20 cases (15.5%) had a history of contact with people with respiratory symptoms from the epidemic area, 17 cases (13.1%) with a confirmed case in the surrounding area or community, 3 cases (2.3%) had a history of contact with a confirmed patient (2 of them were family clustering cases), 38 cases (29.5%) were clinically suspected cases. Clinical symptoms: 121 cases with fever (93.8%), 92 cases with coughing (71.3%), 50 cases with runny nose (38.8%), 32 cases with diarrhea, vomiting or abdominal pain (24.8%). In 102 cases (79.0%), white blood cells were decreased or normal, 103 cases (79.8%) with CRP＜20 mg/L, and 57 cases (44.2%) showed focal infection on chest X-ray or CT scan. Etiological examination: only one case (0.78%) of the family confirmed cases had positive anal swab result, but the throat swab results were negative all the time. The anal swab and throat swab results of other patients and the throat swab results of their accompanying family members were negative. Other pathogens were detected in 61 cases (47.3%), including 14 RSV positive cases, 9 influenza A positive cases, 8 human metapneumovirus positive cases, 6 enterovirus positive cases, 6 influenza B positive cases, 6 Mycoplasma pneumoniae positive cases, 4 parainfluenza virus type 1 positive cases, 1 parainfluenza virus type 3 positive cases, 2 human bocavirus positive cases, 3 adenovirus positive cases, 1 Klebsiella pneumoniae positive cases, 1 Human Staphylococcus positive case, and 1 case with parainfluenza virus type 1 and human bocavirus. The only confirmed patient was followed up while multiple pharyngeal swab results were negative, and the positive anal swab results lasted for 19 days before turning negative and remained asymptomatic. Other patients were followed up on the 3rd, 7th and 14th day after discharge, and no abnormal findings were found. Conclusion Screening/suspected cases of 2019-nCoV infection in children were mostly clinically manifested as respiratory or gastrointestinal symptoms. The diagnosis rate of nucleic acids was extremely low, and there was a possibility of missed diagnosis. Nearly 50% of cases could find other relevant pathogens excluding the 2019-nCoV. The positive rate of anal swab results was higher than that of pharyngeal swab.

Objective The clinical characteristics of patients with influenza A in district hospital were analyzed to provide scientific basis for early diagnosis, prevention and control of influenza A in primary hospital. Methods A total of 628 patients with influenza-like symptoms from Guangzhou Panyu Central Hospital in December 2019 were enrolled, and the clinical data was collected, including gender, age, body temperature, symptoms, and blood test results. According to the result of influenza A nucleic acid detection, patients were divided into negative group and positive group, and the clinical data of these two groups were compared. Results A total of 116 patients were positive in influenza A virus nucleic acid detection, which positive rate was 18.5%. In the positive group, patients aged 14-19 accounted for the largest proportion, with 91 patients (78.4%). The mean age of the positive group was significantly lower than that of the negative group (P＜0.05). Body temperature ranged from 38.1 to 39 ℃ accounted for the largest proportion in the positive group, with 47 patients (46.5%). The mean body temperature of the positive group was significantly higher than that of the negative group (P＜0.01). In terms of symptoms, only the proportion of nasal congestion in positive group was higher than that in negative group (P＜0.05). In terms of blood test results, WBC count, neutrophil absolute value, lymphocyte absolute value and lymphocyte percentage in the positive group were significantly lower than those in the negative group (P＜0.01). Conclusions The majority of patients with influenza A in the winter of 2019 were teenagers, and it was difficult to distinguish influenza A from the common cold only by symptoms. The differential diagnosis should be carried out in combination with the blood routine analysis, especially the decrease in the white blood cell count, the absolute value of neutrophil and the absolute value of lymphocytes.
