Objective:To analyze the clinical characteristics in patients with persistent positive pharyngeal swab of 2019 novel coronavirus Omicron variant and results of nucleic acid testing of anal swabs to provide basis for prevention and control measures.Methods:This study included 93 patients whose pharyngeal swab nucleic acid test were persistent positive and admitted to the ward of Daping Hospital in the National Exhibition and Convention Center (Shanghai) Makeshift Hospital from May 1 to May 24, 2022. The gender, age, underlying diseases, vaccination status, clinical symptoms, interval between infection onset and anal sampling, length of hospital stay, the nucleic acid test result of pharyngeal swabs and anal swabs and the time turning negative were collected and analyzed.Results:The age of 93 patients ranged from 8 to 72 years old with a median of (46.0±16.0) years old. Among them, 30 cases (32.3%) were male and 63 cases (67.7%) were female. Sixty-five patients (69.9%) received 2-3 shots of vaccine, 2 patients (2.1%) received 1 shot, and 26 patients (28.0%) did not receive any vaccination. Twenty patients (21.5%) had underlying diseases, of which hypertension (13 cases, 14.0%) and type 2 diabetes mellitus (6 cases, 6.5%) were the most common. Twenty-four patients (25.8%) had asymptomatic infection and the rest (69 cases, 74.2%) had mild symptoms. Cough (50 cases, 53.8%) and sore throat (28 cases, 30.1%) were the most common clinical manifestations of the upper respiratory tract in these patients. Only 6 patients (6.5%) had gastrointestinal symptoms (including diarrhea in 5 patients and diarrhea with vomiting in 1 patient). Pharyngeal and anal swabs were collected simultaneously from all 93 patients at 8-16th days [(11.55±2.27) days] after 2019 novel coronavirus Omicron variant infection. The pharyngeal swabs were positive in 79 patients (85.0%) and the anal swabs were positive in 5 patients (5.4%). The time of pharyngeal swabs turning negative was (14.7±2.9) days, and that of anal swab turning positive was (14.2±1.9) days. The median length of hospital stay was (16.7±2.9) days.Conclusions:In patients with persistent positive nucleic acid of the 2019 novel coronavirus Omicron variant, there were more mild infection than asymptomatic. The upper respiratory tract symptoms such as cough and sore throat were the most. The likelihood of transmission of 2019 novel coronavirus Omicron variant through the digestive tract may be low. The correlation between gastrointestinal symptoms and 2019 novel coronavirus Omicron variant RNA in the digestive tract is uncertain.

Objective To investigate the diagnostic value of some measured values of CT for nutcracker syndrome(NCS).Methods 28 patients with NCS confirmed by clinical diagnosis and other 81 normal controls were enrolled in the study.The angle between the superior mesenteric artery and the abdominal aorta,and the diameter and the area of left renal vein before/within this angle were measured on enhanced CT and MPR reconstruction images.The ratios of the diameter and the area before the angle to those within the angle were calculated.ROC curve was established to calculate the cut-off value and to evaluate the sensitivity,specificity,positive predictive value and negative predictive value of these parameters.Results In patient group,the mean aortomesenteric angle was 22.4°± 7.16°,mean diameter ratio was 5.10 ± 1.76 and the mean area ratio was 4.07 ± 2.10.In control group,the mean aortomesenteric angle was 61.32°± 22.82°,mean diameter ratio was 1.38 ± 0.40 and mean area ratio was 1.29 ± 0.49.The area under the ROC of the aortomesenteric angle,and the diameter ratio and area ratio were 0.979,1.000 and 0.989 respectively with corresponding cut-off values of 32.5°,2.63 and 2.06,sensitivity of 92.8%,100% and 96.4%,specificity of 95.1%,100% and 92.6%,positive predictive value of 86.7%, 100% and 81.8%,and negative predictive value of 97.5%,100% and 98.7%,respectively.Conclusion The aortomesenteric angle, the diameter and area ratios of left renal vein before/within the aortomesenteric angle have significant diagnostic value in the patients with NCS,and the value of diameter ratio is the highest.

Purpose:Clinical research has been done to show whether continuous infusion of navelbine can increase curative effect and decrease toxicity.Methods:Patients studied were non operable NSCLC and recurrent or metastatic breast cancer. Navelbine is given through a catheter in the venae subclavia by continuous infusion for 24 hours. Regimen:NVB 10 mg/iv/day 1+NVB 10 mg/iv continuous infusion 24 h/day 1—5+DDP 40 mg/iv 2h/day 1—3+Gransetron 3 mg/iv day1,3,5 given every 21 days. Results:Among 47 patients 35 patients were NSCLC and 12 patients were breast cancer. Average age was 58.9 years. Of the NSCLC patients, 12 were squamous cell carcinoma and 23 patients were adenocarcinoma; two patients were stage Ⅱ and 19 patients stage Ⅲ, 19 patients stage Ⅳ. All of the breast cancer cases were infiltrative duct carcinoma. Three patients were stage Ⅱ and nine patients were stage Ⅳ. Of the 47 patients, 44 patients were evaluable for response and 47 patients for toxicity. Response rate of NSCLC was 57%(19 pr) and breast cancer 63% (1 cr, 6 pr). Main toxicity was granulocytopenia and vomiting. WHO Ⅲ—Ⅳ grade granulocytopenia was 40% and vomiting 6.4%. Peripheral nerves toxicity was mild and only 6.4% patients had WHO I grade peripheral sensory nerve damage. No patients had severe nerve toxicity such as enteroplegia.Conclusions:Comparison of continuous infusion Navelbine and Cisplatin with classic usage of navelbine for management of NSCLC and breast cancer showed increased response rate and decreased toxicity. Administration through catheter venae subclavia can avoid chemo phlebitis. [
