Objective:
To explore the effects of different concentrations of glucose solution on the survival of Aedes albopictus and Culex pipiens pallens larvae, the attraction to mosquitoes and egg-laying behaviors, so as to provide the reference for developing mosquito control technology based on sugar bait.
Methods:
White porcelain bowls were filled with 100 mL of 3%, 5%, 8%, 10% and 15% glucose solutions. Ten of fourth instar larvae of Aedes albopictus or Culex pipiens pallens were added to each bowl, and the survival of larvae was recorded after 2, 4, 6, 24, 48 and 72 hours. Egg-laying cups containing 5%, 8% and 15% glucose solution were put in mosquito cages containing fully blooded female mosquitoes of Aedes albopictus and Culex pipiens pallens (50 mosquitoes each), and the total number of eggs laid in 72 hours was observed. The analogous site room was filled with fully blooded and starved female mosquitoes of Aedes albopictus and Culex pipiens pallens (100 mosquitoes each), and simple mosquito control buckets containing 5% and 8% glucose solution and black sticky insect plates. The number of mosquitoes and eggs was observed after 6 days. All the above experiments were repeated 3 times using dechlorinated water as the control.
Results:
The 72 hour corrected mortality rates of Aedes albopictus and Culex pipiens pallens larvae gradually increased with the increase of glucose concentration. The glucose solution with 5% and higher concentrations was not suitable for mosquito larvae to survive. The attraction of egg-laying behaviors to Aedes albopictus and Culex pipiens pallens gradually decreased with the increase of glucose concentration. The effects were similar between 5% and 8% glucose solution, with the averages of 686.67 and 682.33 eggs for Aedes albopictus, and 3.00 and 2.33 egg rafts for Culex pipiens pallens. In analogous site room, there were 93.33, 105.00 and 130.33 adult mosquitoes captured on average in the control group, 5% and 8% glucose solution groups, respectively, with 8% glucose solution group more attractive to adult mosquitoes than the control group (F=3.283, P=0.030); there were 70.33, 55.33 and 63.00 Aedes albopictus eggs (eggs counts+larvae counts) on average, respectively, with statistically significant differences among the three groups (H=6.761, P=0.034).
Conclusion
Glucose solution with concentration of 5% or higher can effectively inhibit the survival of Aedes albopictus and Culex pipiens pallens larvae, and attractive to adult mosquitoes and egg-laying behavoirs.

Objective:To analyze the feasibility and clinical efficacy of reperfusion-expanding-thrombectomy-stenting (RETS) technique in the endovascular treatment of acute carotid artery tandem lesion.Methods:The general clinical data of 88 patients with carotid artery tandem lesion who received emergency endovascular treatment from January 2018 to December 2020 in Department of Neurology, Linyi People′s Hospital were reviewed, the Modified Rankin Scale (mRS) was used as the evaluation standard for the prognosis of patients at 90 days after endovascular treatment, and the clinical data were analyzed, including the recanalization (modified thrombolysis in cerebral infarction ≥2b), perioperative complications and 90-day prognosis, and good prognosis was defined as a mRS score of 0-2.Results:A total of 88 patients with tandem carotid artery disease were included,48 of whom were treated with RETS technique, 40 were treated with anterograde approach. Compared with antegrade recanalization, RETS technique had significant differences in the time from puncture to recanalization [(72.06±17.29) min vs (98.88±26.09) min, t=-5.56, P<0.001] and the primary recanalization rate [35/48(73.0%) vs 21/40(52.5%),χ2=3.93 ,P=0.047], with statistically significant difference. There was no significant difference in clinical prognosis and surgical complications between the two methods (all P>0.05). Conclusions:RETS technique can shorten the operation time and increase the primary recanalization rate. RETS technique is safe and feasible for the treatment of carotid tandem lesions.

Journal of Preventive Medicine 2022;34(4):380-384
Objective:
To investigate the origin of infection and risk factors of a case with SARS-CoV-2 infection associated with overseas countries in the Ningbo-Zhoushan Port, Zhejiang Province, so as to provide the evidence for improving the COVID-19 control measures at ports.
Methods:
Ningbo Center for Disease Control and Prevention ( CDC ) and Beilun CDC conducted case finding and epidemiological surveys immediately after being informed. The general information, history of vaccination and the travel during the latest 14 days were collected from the positive case, and all close contacts were tracked. Saliva samples were collected for SARS-CoV-2 nucleic acid testing and whole-genome sequencing, and the sequencing results were aligned with the GISAID's EpiCoV database. The origin of infection and transmission route of the positive case was investigated.
Results:
A case was identified positive for SARS-CoV-2 nucleic acid during company M's routine screening in the Ningbo-Zhoushan Port on August 10, 2021, and was confirmed positive for SARS-CoV-2 nucleic acid by Beilun CDC and Ningbo CDC on August 11. Whole-genome sequencing showed SARS-CoV-2 B.1.617.2 ( Delta ) variant, which shared the highest homology with the virus sequence uploaded by Russia on June, 2021 ( Russia/MOW-RII-MH27356S/2021 ). The case was a bundling worker for overseas container ships, and reported communicated with foreign boatmen and contacted materials without protected interventions on the SINOKOR AKITA Container Ship between August 4 and 5, 2021. This ship anchored at Vladivostok, Russia from July 27 to 29, anchored at Ningbo Harbor on August 4, and departed on August 5. Then, 11 boatmen from this ship were tested positive for SARS-CoV-2 nucleic acid on August 8. One asymptomatic case was reported in this epidemic; 254 close contacts and 617 secondary close contacts were identified, and all were tested negative for SARS-CoV-2 nucleic acid. No new cases with SARS-CoV-2 infections were detected until August 25, 2021, and the emergency response was therefore terminated.
Conclusions
The infection was a sporadic COVID-19 epidemic associated with overseas countries, which was caused by Delta variant infection through contacts with foreign boatmen or materials by a bundling worker in Ningbo-Zhoushan Port; fortunately, no epidemic spread occurred. Intensified closed-loop management and increased frequency of SARS-CoV-2 nucleic acid test among high-risk populations, and improving the precision and rapid emergency treatment of COVID-19 epidemics are required for the containment of COVID-19 at ports.

Objective: To investigate whether grain-sized moxibustion at Xinshu (BL15) and Shenshu (BL23) can alleviate cognitive decline and other pathologic features in early-stage Alzheimer disease (AD) using transgenic mice with 5 familial AD mutations (5XFAD). Methods: The genotype of transgenic mice was detected by polymerase chain reaction. A total of 40 transgenic mice (1.5 months old) were randomly and equally allocated to an AD model group (5XFAD group) or a grain-sized moxibustion group (5XFAD + GM group), with 20 wild-type (WT) mice (C57BL/6J) serving as the normal control group (WT group). Mice in the 5XFAD + GM group were treated by grain-sized moxibustion at bilateral Xinshu (BL15) and Shenshu (BL23). Mice in the WT group and 5XFAD group received no treatment but were restrained to ensure exposure to a similar experimental condition. Cognitive function and memory were assessed with the Morris water maze and Y-maze tests. The amyloid β 40 (Aβ40) and amyloid β 42 (Aβ42) levels in the brain were evaluated by enzyme-linked immunosorbent assay; amyloid plaque deposition in brain tissue sections was detected by thioflavin-S staining; the expression of glial fibrillary acidic protein (GFAP), cluster of differentiation 11b (CD11b), brain-derived neurotrophic factor (BDNF), and choline acetyltransferase (ChAT) in the hippocampus and prefrontal cortex was analyzed by immunohistochemistry. Results: In the Morris water maze test, compared with the 5XFAD group, mice in the 5XFAD + GM group had a shorter escape latency and more target area crossings and spent more time in the target quadrant (P<0.05). In the Y-maze test, compared with the 5XFAD group, the number of training times of the 5XFAD + GM group was significantly decreased (P<0.05), together with more correct responses (P<0.05). Compared with the 5XFAD group, the levels of Aβ40 and Aβ42 in the brain tissue of the 5XFAD + GM group were significantly lower (P<0.05); in the hippocampus and prefrontal cortex, the total number of amyloid β plaque deposition were significantly lower (P<0.05); the expression levels of GFAP and CD11b were significantly reduced (P<0.05); and the expression levels of ChAT and BDNF were significantly increased (P<0.05).Conclusion: Grain-sized moxibustion at Xinshu (BL15) and Shenshu (BL23) greatly improves learning and memory functions, decreases the levels of Aβ40 and Aβ42, inhibits amyloid β plaque deposition, decreases the expression of GFAP and CD11b, and increases the expression of ChAT and BDNF in AD mice to inhibit the progression of AD.

Objective:To investigate the relationship between the dose of preoperative neoadjuvant radiotherapy and the pathologic complete response (pCR) rate in patients with locally advanced squamous cell esophageal cancer (ESCC).Methods:Clinical data of 116 patients with ESCC who received neoadjuvant chemoradiotherapy followed by esophagectomy in our cancer center from July 2017 to December 2019 were retrospectively analyzed. The radiation doses were divided into 2 ranges based on Grays (Gy) received: 40-45 Gy and 45 Gy or more.Results:The overall pCR rate was 38. 8%(45/116). pCR was observed in 35 out of 80(44%) patients treated with 40-45 Gy and 10 of 36(28%) patients treated with 45 Gy or more. The pCR rate did not significantly differ between two groups [(40-45 Gy) vs.( ≥ 45 Gy), P=0.105)]. Conclusions:Preoperative neoadjuvant radiotherapy with a higher dose (≥ 45 Gy) fails to increase the pCR rate in patients with locally advanced ESCC. Prospective randomized trials are required to determine the optimal dose of preoperative adjuvant radiotherapy.

Objective:To explore whether CD5 + CD19 + B cells has the function of secreteing interleukin-10 (IL-10) in vitro, and to further investigate its possible effects and mechanisms on CD8 + cells in the process of hepatitis B virus (HBV) infection. Methods:From July 2017 to June 2018, at Wuxi Second People′s Hospital Affiliated to Nanjing Medical University, 23 patients with chronic hepatitis B (chronic hepatitis B group), 18 patients with liver cirrhosis (liver cirrhosis group) and 19 healthy individuals in the same period as healthy controls (healthy control group) were enrolled. Peripheral blood mononuclear cell (PBMC) were isolated and cultured. CD5 + CD19 + B cells were isolated. The cells were analyzed by flow cytometry. The ratio of high CD5 + CD19 + B cells content (>6 % of lymphocytes), the secretion of IL-10 by CD5 + CD19 + B and the ratio of high IL-10 + cells content (>4 % of lymphocytes) of three groups were compared. The effects and possible mechanisms of CD5 + CD19 + B cells on the secreting of interferon-γ (IFN-γ) by CD8 + cells were analyzed. Liver biopsy and immunohistochemistry examination were conducted in 18 patients (13 patients with chronic hepatitis B and 5 patients with liver cirrhosis) and the expression of CD5 + CD19 + B cells in human liver tissues was analyzed. Chi square test and Fisher exact probability test were used for statistical analysis. Results:The ratio of high CD5 + CD19 + B cells content of liver cirrhosis group was higher than that of healthy control group (8/18 vs. 2/19) and the difference was statistically significant (Fisher exact probability test, P=0.029). The precentage of CD5 + CD19 + B cells in healthy control group ( n=10), chronic hepatitis B group ( n=23) and liver cirrhosis group ( n=18) accounted for 81.6%, 82.3% and 70.1%of IL-10 + cells, respectively, and the number of patients with high IL-10 + cells precentage was 2, 7 and 2, respectively. There were no statistically significant differences among three groups (all P>0.05). After stimulated with lipopolysaccharide and cultured for 48 hours, the precentage of CD8 + IFN-γ + cells in lymphocytes of healthy control group ( n=10), chronic hepatitis B group ( n=10) and liver cirrhosis group ( n=10) were compared, and the differences were not statistically significant (all P>0.05). After CD5 + CD19 + B cells were eliminated, the precentage of CD8 + IFN-γ + cells in lymphocytes increased in 5, 4 and 4 patients of healthy control group ( n=10), chronic hepatitis B group ( n=10) and liver cirrhosis group ( n=10). After adding IL-10 receptor blocker, the precentage of CD8 + IFN-γ + cells in lymphocytes in PBMC increased compared with that before the addition of IL-10 receptor blocker (7.23% vs. 6.87%). The results of immunohistochemistry examination of liver biopsy indicated that CD4 + and CD8 + cells were strong expressed in portal area of liver tissue of patients, while CD5 + and CD19 + were less expressed. Conclusions:CD5 + CD19 + B cells do not show obvious quantitative and functional differences in the process of chronic HBV infection, however the ability of CD8 + cells to secrete IFN-γ, which may be achieved by secreting IL-10 rather than by direct contact between cells.
