Objective To determine the treatment effect of cesarean scar pregnancy (CSP) and provide theoretical guidance in selecting proper treatment for this disease. Methods Sixty-two patients were randomly divided into 2 groups taken uterine artery embolization combines uterine curettage (combination group,n = 32) and gynaecologic surgery (surgery group, n = 30) respectively. The operation time, blood loss, intraoperative fluid volume, uterine retention rate, hospitalization days and medical expense of two groups were recorded and compared.The complication occurrence of both short-term and long-term was observed, and the results in two groups were compared. Long term and short term occurrence of complications were also observed. Results No significant difference in preoperative indicators was found between two groups, includes average age, menopause time, blood β-HCG value,gestational sac diameter,the amount of vaginal bleeding (P ＞ 0. 05 ). But after the operation,we found significant difference between the combination group and surgical group in uterine retention rates (96.9% (31/32)and 20.0% (6/30) respectively, P ＜ 0. 01 ). The significant differences were also observed in operative time (42. 0 ±13.2) min and ( 120.0 ± 34.5 ) min respectively, P ＜ 0. 001 ); average hospitalization days ( (7.0 ± 1.0)days and ( 15.0 ± 2.0) days respectively, P ＜ 0. 001 ); medical expense ( $ 9143.5 ± 864.3 and $ 11 371.7 ±1621.0 respectively, P ＜ 0. 001 ) between the combination group and surgical group. During hospitalization,complication occurred in 1 case in combination group and in 7 cases in surgery group, of which mild complications were seen in 6 and serious complication in 1 patient. No treatment-related complications occurred in long-term observation in neither of the groups. The complication occurrence in combination group and surgery group were 3.1%(1/32) and 23.3% (7/30) respectively ,with a significant difference between two groups (P ＜ 0.01 ). Conclusions In the treatment of cesarean scar pregnancy, the uterine artery embolization combines uterine curettage therapy is superior to gynaecologic surgery for its shorter operative time, less infusion quantity, higher uterine retention rate,fewer complications, shorter time of hospitalization, less medical expense and better security.

We purified a novel mannose binding lectin form Musca domestica pupae by affinity chromatography on Con A-Sepharose 4B and DEAE weak anion-exchange chromatography. By SDS-PAGE, MBL-1 yielded a single band with the molecular weight of 24 kDa. It was a glycoprotein detected by periodic acid-schiffs staining reaction, with 97.36% protein and 2.1% oligosaccharide. Meanwhile, the results of beta-elimination reaction, infrared spectroscopy, atomic force microscopy and protein sequencing instrument show that MBL-1 was an ellipsoidal-shaped monomer with 60-100 nm in diameter. N-glycoside bond linked oligosaccharide chain and the N-terminal blocked peptide chain. Further study suggested that MBL-1 promote the proliferation of macrophage in a concentration-dependent manner. The scanning electron microscope analysis shows that MBL-1 promoted the activation of macrophages. These results show that MBL-1 purified from Musca domestica pupae possesses immune regulation effect, serving a reference basis to develop natural immune-modulator.

Objective:To investigate the epidemiological characteristics of influenza-like illnesses (ILI) and the etiological characteristics of influenza viruses in Minhang District of Shanghai from 2010 to 2021.Methods:The surveillance data collected by influenza surveillance sentinel hospitals and the influenza laboratory network from the first week of 2010 to the 52 nd week of 2021 were used for a statistical analysis. Results:A total of 122 903 cases with ILI were reported by the national influenza surveillance sentinel hospitals in Minhang during 2010 to 2021, and the average percentage of ILI cases was 0.94%, showing an increasing trend ( P<0.001). Among them, those aged 0-4, 5-14, 15-24, 25-59 and ≥60 years accounted for 4.35%, 13.30%, 14.30%, 54.32% and 13.73%, respectively. The percentage of ILI showed obvious periodicity. The seasonal incidence of ILI peaked from December to February and from July to September. But the winter peak at the beginning of 2013 was postponed. There was no significant peak in 2021. A total of 11 625 samples were tested from 2010 to 2021, in which the detection rate of influenza viruses was 20.92% (2 432/11 625). The positive rate was 12.83% (1 492/11 625) for influenza A viruses and 8.09% (940/11 625) for influenza B viruses, indicating that the epidemic intensity caused by influenza A viruses was greater than that caused by influenza B viruses. The overall positive rates for influenza A/H3N2 virus, influenza A/H1N1 virus, influenza B/Victoria lineage and influenza B/Yamagata lineage were 9.04% (1 051/11 625), 3.79% (441/11 625), 2.69% (313/11 625) and 2.19% (255/11 625) during 2010 to 2021. The predominant circulating strains altered between influenza A and influenza B viruses in Minhang District of Shanghai during 2010 to 2019. It generally took six months for an epidemic strain to be replaced by a new one. No obvious regularity was observed in 2020 or 2021. The tendency of the incidence of ILI reported from 2010 to 2019 was basically the same as that of the positive rate of influenza viruses, while there were significant differences in 2020 and 2021. Conclusions:Influenza viruses circulated seasonally in Minhang District of Shanghai with alternating prevalent viral subtypes and the infections mostly occurred in the winter and summer seasons. During the epidemic of COVID-19, the intensity of influenza was decreased, but with the normalization of prevention and control measures, the influenza epidemic showed an obvious upward trend. Therefore, it was important to strengthen the prevention and monitoring of influenza and analyze the virus variations in time.
