Objective To investigate the effect and mechanism of compound glycyrrhizin on airway inflammation in asthmatic rats. Methods Forty wistar rats were randomly divided into health group (group Ⅰ), asthma group(group Ⅱ), treating group (group Ⅲ) and treating control group (group Ⅳ) (n=10 in each group). Group Ⅱ, group Ⅲ and group Ⅳ received intraperitoneal injection of ovalbumin (OVA) and aluminum hydroxide gel for sensitization and OVA aerosol by ultrasonic nebulization for challenge, in addition, group Ⅲ re-ceived intraperioneal injection of 200 μg of compound glycyrrhizin 1 hour before OVA aerosol challenging every time, and group Ⅳ were in-jected with normal saline instead of compound glycyrrhizin. Group Ⅰ were injected and nebulizated with normal saline instead of OVA and alu-minlum hydroxide. All rats were sacrificed at the 6th hour after the last challenging, venous blood and bronchoalveolar lavage fluid(BALF) were collected, the IgE in venous blood were determined and the concentration of IL-4, IL-5, IL-13 and IFN-γ in BALF were detected, the cells in BALF were counted and detached. Results The concentration of IgE, IL-4, IL-5, IL-13 and the count of neutrophilic granulocytcs, lymphocytes, cosinophils in group Ⅱ were significantly higher than those in group Ⅰ and group Ⅲ(P<0.01), and the concentration of IFN-γ in group Ⅰ and group Ⅳ were significantly lower than those in group Ⅰ and group Ⅲ(P <0.01). There was no significant difference be-tween group Ⅱ and group Ⅳ(P >0. 05). The concentration of IgE, IL-4, IL-5, IL-13 and the count of neutrophilic granulocytes, lympho-cytes, cosinophils in group Ⅲ were higher than those in group Ⅰ, and the concentration of IFN-γ and the count of mononucleat macroplile cells in group Ⅲ were lower than those in group Ⅰ, but there were no significant difference(P>0.05). Conclusion Compound giycyrrhiz-in alleviated the airway inflammation and reduced the airway hyperresponsiveness in asthmatic rats, which mechanism may be related to regu-lating the balance of Th1/Th2 cytokines, suppressing the immune ability of Th2 and promoting the immune ability of Th1.

Purpose To observe white matter structure features of patients with early stage (Hoehn-Yahr 1-2 phase) Parkinson''s disease (PD) by using diffusion tensor imaging (DTI) based on the fiber bundle analysis tract-based spatial statistics (TBSS); and to explore the brain regions of PD patients in which DTI parameters are significantly correlated with unified Parkinson''s disease rating scale (UPDRS) score elevation. Materials and Methods DTI sequence was performed on 27 cases of PD and 30 cases of healthy volunteers. DTI parameters including fractional anisotropy (FA), mean diffusivity (MD), axial diffusivity (AD), and radial diffusivity (RD) were analyzed in all participants by using TBSS technique, and the parameters of two groups were compared. The correlation of clinical UPDRS score with FA value, MD and RD value in the PD group were analyzed.Results Compared with that in the control group, FA values of several brain regions in PD group decreased, while MD and RD value increased (P<0.05). AD showed no obvious change (P>0.05). UPDRS score of PD group was correlated with FA, MD and RD value (P=0.001). The brain regions that showed FA value decreased, MD and RD value increased included corpus callosum, left anterior limb of internal capsule, bilateral anterior radial crown, bilateral superior radial crown and left posterior thalamic radiation (P=0.001).Conclusion There is some changes in white matter structure of the patients with early stage Parkinson''s disease, which may due to demyelination or fiber integrity damaged.

Objective To explore the clinical significance of detecting homocysteine (Hcy), C-reactive protein (CRP)and ankle brachial index (ABI)in elderly patients with lower limb artherosclerosis.Methods A total of 85 elderly patients with lower limb artherosclerosis in our hos-pital from Feb.2007 to Oct.2010 were divided into plaque group (37 cases)and non-plaque group (48 cases)according to the intima-media thickness (IMT)detected with ultra-sound.And another 40 elderly patients with non-lower limb artherosclerosis served as control group.Hcy,hs-CRP and ABI characteristics were retrospectively analyzed among 3 groups and cardiovascular events were compared between plaque and non-plaque groups.Results Hcy and hs-CRP expression levels de-creased gradually whereas ABI increased gradually and there were significant differences among 3 groups (P <0.05 or P <0.01).The rates of cardiovascular events of plaque and non-plaque groups were 10.81% (4 /37)and 4.17% (2 /48),respectively,but the difference was not statistically sig-nificant (P >0.05).Conclusion Elderly patients with lower limb artherosclerosis have abnormal Hcy metabolism,and increased CRP expression and decreased ABI value can provide significant ref-erences for clinical diagnosis.

Objective: To investigate the effects of resolvin D1 on autophagy in the prevention of acute pancreatitis (AP) in mice. Methods: Thirty C57BL/6 mice were divided into control group, AP group and resolvin D1 group. AP model was established by intraperitoneal injection of cerulein at 50 μg·kg^-1·h^-1. Resolvin D1 was intraperitoneally given at 50 μg/kg one hour before and four hours after modeling. The mice of control group were intraperitoneally injected the same volume of 0.9% sodium chloride solution. The serum levels of amylase and lipase were measured by colorimetric method. The pathological injury of the lung and pancreatitis were observed under optical microscope. Autophagic vacuoles in acinar cells of pancreas of mice were evaluated by transmission electron microscope. And the expressions of autophagy related markers Beclin-1, p62 and LC3-Ⅱ at the mRNA and protein levels in pancreas of mice were detected by real time quantitative polymerase chain reaction (RT-qPCR) and Western blotting method. One-way analysis of variance and SNK-q were performed for statistical analysis. Results: There were statistically significant differences in serum amylase and lipase levels between control group, AP group and resolvin D1 group (F=62.99 and 149.69, both P<0.01). The serum amylase and lipase levels of mice in resolvin D1 group were lower than those of AP group ((525.08±41.12) U/L vs. (752.62±42.03) U/L, (758.24±134.77) U/L vs. (1 201.06±112.53) U/L), and the differences were both statistically significant (both SNK-q test and P<0.01). In addition, there were statistically significant differences in the ratio of the pancreas and lung wet mass to body mass between control group, AP group and resolvin D1 group (F=11.36 and 18.51, both P<0.05). Pathological injury scores of pancreas and lung of resolvin D1 group were both lower than those of AP group (3.3±0.6 vs. 5.6±0.6, 5.4±0.5 vs. 8.8±0.4), and the differences were statistically significant (both SNK-q test and P<0.05). The results of transmission electron microscopy observation revealed that the number of autophagic vacuole of resolvin D1 group was less than that of AP group, and the size was smaller. Moreover, there were statistically significant differences in Beclin-1, p62 and LC3-Ⅱ mRNA between control group, AP group and resolvin D1 group (F=270.95, 151.83 and 124.77, all P<0.05). The relative expression mRNA levels of Beclin-1, p62 and LC3-Ⅱ of resolvin D1 group were 1.59±0.12, 2.75±0.27 and 1.34±0.14, respectively, which were lower than those of AP group (2.68±0.13, 3.32±0.30 and 3.37±0.26, respectively), and the differences were statistically significant (all SNK-q test and P<0.05). There were statistically significant differences in the expressions of Beclin-1, p62 and LC3-Ⅱat the protein level between control group, AP group and resolvin D1 group (F=116.63, 384.40 and 192.45, all P<0.05). The expressions of Beclin-1, p62 and LC3-Ⅱ at protein level of resolvin D1 group were 0.98±0.03, 0.57±0.04 and 0.31±0.03, respectively, which were lower than those of AP group (1.34±0.07, 1.02±0.03 and 0.48±0.04, respectively), and the differences were statistically significant (all SNK-q test and P<0.05). Conclusion Resolvin D1 ameliorates the severity of AP by attenuating the impaired autophagy and restoring autophagic flux in AP mice.

Objective: To report an investigation of a family cluster of coronavirus disease 2019 ( COVID-19 ) in Ningbo, so as to provide reference for the prevention and control measures. Methods: According to the COVID-19 Prevention and Control Program ( fourth version ) , an epidemiological investigation was conducted to collect the demographic information, clinical features and exposure history, to find the close contacts, and to figure out the source and route of infection. Results: Twelve confirmed cases and one asymptomatic case were reported. The attack rate was 16.05%. Among them, five were males and eight were females; the age ranged from 11 to 85 years old, with a median of 39 years old; most had mild symptoms. The incubation period was 2-13 days, with a median of 6.5 days. The first case ( Case 1 ) developed the symptoms on January 22, and had close contact with Zhang, an asymptomatic case, on January 20. Zhang was related to a cluster in the Buddhist assembly on January 19. Case 1, who caused the spread of the epidemic among family members, participated in several family visits and dinners from January 22 to 27 with other 24 families, resulting in six secondary cases and six third-generation cases. There were 54 close contacts except the family members, no infection was found. Conclusion This family cluster may result from the close contact with an asymptomatic case, and then spread within families through having dinners and living together.

Objective:To study the complications of irreversible electroporation (nano-knife) ablation on locally advanced pancreatic cancer, and to analyse the causes of complications and related treatment.Methods:The clinical data of 36 patients with locally advanced pancreatic cancer treated with nano-knife ablation at the Fifth Affiliated Hospital of Zhengzhou University from January 2016 to March 2019 were studied retrospectively. The types and incidence of postoperative complications were analyzed. The complications were classified according to the Clavien-Dindo classification, and the severity of the complications was evaluated.Results:There were 15 patients (41.7%) who developed various degrees of complications, including splenic infarction, atrial fibrillation, portal vein thrombosis, pancreatic fistula, pseudoaneurysm, gastrointestinal bleeding, liver abscess and severe pancreatitis. Among them, 6 patients (16.7%) had grade III complication or above. Three (8.3%) patients with grade Ⅲ complications died of upper gastrointestinal bleeding 3 months after operation.Conclusions:Various complications might occur after nano-knife ablation, with postoperative gastrointestinal and abdominal bleeding being the main complications which resulted in death. Measures which can effectively reduce occurrence of complications need to be studied.
