Objective:To analyze and summarize the characteristics and rules of upper airway computerized tomography (CT) in obstructive sleep apnea (OSA) patients with epiglottic collapse.Methods:As a cross-sectional study, OSA patients (all were male, aged 18 to 60) who received Han-uvulopalatopharyngoplasty (H-UPPP) surgery at Second Affiliated Hospital of Zhejiang University School of Medicine from April 2023 to February 2024 were continuously selected. All patients underwent physical examination, polysomnography (PSG) and three-dimensional CT plain scan of upper airway before surgery. Preoperative drug-induced sleep endoscopy (DISE) was performed on the day of surgery. According to the findings of DISE, all patients were divided into two groups: epiglottic collapse group and non-epiglottic collapse group. The relevant data were collected, and the measured data included epiglottic length, epiglottic width, epiglottic curvature, epiglottic angle, distance between epiglottis and posterior pharyngeal wall, distance between epiglottis and tongue base, angle between epiglottis and tongue base, the lymph tissue classification of the tongue base, airway length, mandibular - hyoid bone distance, soft palate length and soft palate - hard palate Angle. Statistical analysis was performed using SPSS 25.0.Results:There were a total of 104 patients with OSA, consisting of 27 patients with epiglottic collapse and 77 patients with non-epiglottic collapse. In this study, the incidence of epiglottic collapse was 25.96%. There were no significant differences in apnea hyponea index (AHI), minimum blood oxygen saturation and the time ratio of blood oxygen saturation below 90% (TS90) between the two groups (all P>0.05). Compared with the non-epiglottic collapse group, the epiglottic length [(19.77±2.42)mm vs. (18.54±2.62)mm, t=2.162, P=0.033] and the lymph tissue classification of the tongue base [4(1,4) vs.2(1,3), Z=-2.968, P=0.003] in the epiglottic collapse group increased. Distance between epiglottis and tongue base reduced [2.70(0,5.88) mm vs. 5.45(2.15,6.98)mm, Z=-2.385, P=0.017]. According to Logistic regression analysis, epiglottic collapse and epiglottic width ( OR: 1.201; 95% CI: 1.009-1.430, P=0.039) were positively correlated, epiglottic curvature ( OR: 0.979; 95% CI: 0.961-0.998, P=0.030) was negatively correlated, and with the grade of lymph tissue of tongue root ( OR: 1.936; 95% CI: 1.294-2.896, P=0.001) was positively correlated. Conclusion:CT examination in awake OSA patients with epiglottic collapse can reveal its characteristic indicators. The wider the epiglottic width, the smaller the epiglottic curvature, and the larger the lymph tissue grade of the base of tongue were effective predictors of epiglottic collapse.

The clinical randomized controlled trial(RCT) of Chinese patent medicine in the treatment of influenza were reviewed and analyzed to provide basic information for clinical decision and related research. On the basis of the collection in the Traditional Chinese Medicine(TCM) Clinical Evidence Database System(EVDS), CNKI, Wanfang, VIP, SinoMed, EMbase, PubMed, and Cochrane Library were searched for RCTs of Chinese patent medicine for influenza published from database inception to July 25, 2021. The publication time, sample size, intervention and control measures, course of treatment, outcome indicators, and methodological quality of the trials were analyzed and evaluated. Ninety-two RCTs of Chinese patent medicine for influenza published between 2005 and 2021, were included, among which 17 RCTs(18.48%) had a sample size higher than 200 and the average sample size was about 145. Twenty-seven Chinese patent medicines were involved, including twenty-one oral medicines and six injections. The Chinese patent medicines in trials reported in more than five papers included Lianhua Qingwen Capsules/Gra-nules, Tanreqing Injection, and Reduning Injection. Fourteen intervention protocols were reported, of which Chinese patent medicine+western medicine+conventional treatment vs western medicine+conventional treatment(20.65%) was the most frequently employed. Additionally, 85.87% of the RCTs reported the course of treatment, and 80.43% of the RCTs determined 3-7 d as the intervention course. Forty-five outcome indicators were extracted, which were used 434 times, including symptoms/signs, physicochemical detection, safety events, TCM symptoms/syndromes, quality of life, long-term prognosis, and economic evaluation. Symptoms/signs(61.52%) exhibited the highest frequency. Methodological problems were prevalent in the included trials. The findings reveal that there are few clinical trials on influenza treatment by Chinese patent medicine, and the methodological problems are prominent, affec-ting the reliability and practicability of the trials. In the future research, the value characteristics of Chinese patent medicine should be highlighted and the quality control in the whole process should be strengthened based on the scientific and rigorous design.

Objective:To explore the application value of dual contrast-enhanced ultrasound in the differential diagnosis of renal cystic lesions.Methods:Eighty-four cases with renal cysts who were diagnosed by routine ultrasound in Zhejiang Cancer Hospital and Zhejiang Xiaoshan Hospital from January 2019 to October 2020 were included in the study. Intravenous contrast-enhanced ultrasound and enhanced MRI were performed to differentiate benign and malignant cysts. Patients with benign cysts underuent intravenous pyelography and intracapsular contrast-enhanced ultrasound. Before sclerotheraphy to exclude renal pelvic cysts. The diagnostic results of dual radiography were compared with MRI and intravenous pyelography.Results:Among 84 patients with suspected renal cysts, the diagnostic accuracy of enhanced MRI for cystic renal cancer was 97.62%, and the sensitivity was 97.62%. The diagnostic accuracy of intravenous contrast-enhanced ultrasound was 98.81, the sensitivity was 100%, and the specificity was 98.73%. There was no statistically significant difference between the two groups (all P>0.05). 77 cases were diagnosed as benign renal cysts, the detection rate of intravenous pyelography was 9.1% (7/77), the detection rate of renal pelvic cysts by intracystic ultrasonography was 6.5% (5/77). With intravenous pyelography as the gold standard, the diagnostic accuracy of intracapsular contrast-enhanced ultrasound was 97.4% (75/77), the sensitivity was 71.4% (5/7), and the specificity was 100% (70/70). Conclusions:Compared with enhanced magnetic resonance and intravenous pyelography before renal cyst sclerosing therapy, there is no difference in diagnostic efficiency of double contrast ultrasound for benign and malignant cysts. The diagnostic efficiency of renal pelvic cysts is high, and the operation is convenient. It can identify cystic renal cancer and cysts from the renal pelvis and improve the safety of sclerotherapy.

Huang-Qin Decoction (HQD) is a classic prescription for diarrhea in Chinese medicine treatment. Recent studies have demonstrated that HQD and its modified formulation PHY906 could ameliorate irinotecan (CPT-11) induced gastrointestinal (GI) toxicity and enhance its anticancer therapeutic efficacy. Nevertheless, which constituents in HQD are effective is still unclear so far. The study aims to screen out the key bioactive components combination from HQD that could enhance the anticancer effect of CPT-11. First, the potential bioactive constituents were obtained through system pharmacology strategy. Then the bioactivity of each constituent was investigated synthetically from the aspects of NCM460 cell migration, TNF-α release of THP-1-derived macrophage and MTT assay in HCT116 cell. The contribution of each constituent in HQD was evaluated using the bioactive index E

To systematically review the effects of probiotic supplementation on the prevention and treatment of asthma. A computerized literature search was conducted in CNKI,CBM,VIP,Wanfang,PubMed,Embase,Cochrane Library,and Web of Science from their inception to February,2019 to collect all relevant studies. Cochrane Collaboration's risk of bias tool was used to assess the methodological quality of the included studies. Twelve studies were included in the systematic review of the value of probiotics in asthma prevention. The results showed that probiotic supplementation was not significantly associated with a lower risk of asthma (=0.95,95%=0.82-1.11) or wheeze (=0.99,95%=0.88-1.11). Subgroup analyses based on interventions did not show significant differences. Six studies were included in the systematic review of the role of probiotics in asthma treatment. The results showed that probiotic supplementation improved pulmonary function and asthma control in asthmatic patients. However,more studies are needed to validate this effect. Moreover,further studies are needed to clarify the effect of probiotics on the immune markers and the use of asthmatic drugs in asthmatic patients. Based on the currently available literature,probiotic supplementation can not prevent asthma or wheeze. However,it may improve pulmonary function and asthma control in asthmatic patients,although further studies are needed.
