Echinococcus granulosus cyst fluid(EgCF) inhibits the migration and phagocytic function of mouse macrophages induced by LPS via inducing cytoskeletal rearrangement / 细胞与分子免疫学杂志

Objective To investigate the effect of Echinococcus granulosus cyst fluid(EgCF) on the cytoskeletal rearrangement and phagocytosis and the migration of macrophages induced by lipopolysaccharide(LPS). Methods Peritoneal macrophages of C57BL/6 mice were isolated and cultured in vitro, and divided into control group and LPS group and LPS combined with EgCF group. After 48 hours of treatment, filamentous actin (F-actin) changes were observed with rhodamine-labelled phalloidin staining and fluorescence microscopy; TranswellTM chamber was used to test cell migration ability and flow cytometry to test cell phagocytosis. After 1 hour of treatment, PI3K and AKT, phosphorylated AKT (p-AKT), Rac1, guanosine triphospho-Rac1 (GTP-Rac1), WASP and Arp2 protein expressions were detected with Western blot analysis. Results Compared with the control group, after LPS stimulation, macrophages were deformed significantly; pseudopodia increased; actin cytoskeleton increased and was more distributed in pseudopodia; the ability of migration and phagocytosis were significantly improved, and the expression of PI3K, p-AKT, GTP-Rac1, WASP and Arp2 proteins significantly increased. EgCF treatment caused cell shrinkage and disappearance of pseudopodia protrusions of LPS-activated cells, and led to the reduced phagocytic and migratory of cells; the protein expression of PI3K, p-AKT, GTP-Rac1, WASP and Arp2 decreased significantly compared with the LPS group. Conclusion LPS induces the migration and enhances phagocytosis of macrophages while EgCF inhibits these effects, which is related to actin cytoskeleton rearrangement.

Effect of intraoperative Viatorr stent implantation for shunting of blood flow in the left or right branch of the portal vein and its effect on clinical outcome in patients with cirrhotic portal hypertension undergoing transjugular intrahepatic portosystemic shunt / 临床肝胆病杂志

ObjectiveTo investigate the effect of intraoperative Viatorr stent implantation for shunting of blood flow in the left or right branch of the portal vein on the clinical outcome of patients with cirrhotic portal hypertension undergoing transjugular intrahepatic portosystemic shunt (TIPS). MethodsA retrospective analysis was performed for the clinical data of 120 patients with cirrhotic portal hypertension who underwent TIPS in The General Hospital of Western Theater Command from March 2016 to December 2019, and according to the target position of portal vein puncture determined by intraoperative angiography, the patients were divided into left branch group and right branch group. The two groups were compared in terms of the incidence rates of postoperative recurrence and bleeding, stent dysfunction, and hepatic encephalopathy (HE) and survival. The t-test was used for comparison of continuous data between two groups, and the chi-square test was used for comparison of categorical data between two groups. The Kaplan-Meier curve was used to calculate rebleeding rate, stent patency rate, incidence rate of HE, and survival rate. ResultsThe surgical success rate was 100% for all 120 patients, with a short-term hemostasis rate of 100%. Among the 120 patients, 52 underwent shunting of the left branch of the portal vein and 68 underwent shunting of the right branch. There was a significant reduction in portal venous pressure after surgery (9.98±2.84 mm Hg vs 24.72±5.11 mm Hg, t=37.76, P＜0.01). The cumulative rebleeding rates at 12 and 24 months after surgery were 3.2% and 11.0%, respectively, and the cumulative incidence rates of HE at 3, 6, 12, and 24 months after surgery were 10.8%, 13.6%, 21.2%, and 24.5%, respectively. Among the 29 patients who experienced HE, 23 had grade Ⅰ-Ⅱ HE and 6 had grade Ⅲ HE. The cumulative incidence rates of stent dysfunction at 12 and 24 months after surgery were 7.1% and 21.4%, respectively. The cumulative survival rates at 12 and 24 months after surgery were 92.0% and 86.5%, respectively. As for comparison of the left branch group and the right branch group, there were no significant differences in postoperative stent patency rate, rebleeding rate, incidence rate of HE, and survival rate(all P＜0.05). ConclusionTIPS is a safe and effective method for the treatment of cirrhotic portal hypertension, and intraoperative Viatorr stent implantation, no matter for establishing the shunt of the left or right branch of the portal vein, will not affect the clinical outcome of patients.

Spatial Properties of Mismatch Negativity in Patients with Disorders of Consciousness / 神经科学通报·英文版

In recent decades, event-related potentials have been used for the clinical electrophysiological assessment of patients with disorders of consciousness (DOCs). In this paper, an oddball paradigm with two types of frequency-deviant stimulus (standard stimuli were pure tones of 1000 Hz; small deviant stimuli were pure tones of 1050 Hz; large deviant stimuli were pure tones of 1200 Hz) was applied to elicit mismatch negativity (MMN) in 30 patients with DOCs diagnosed using the JFK Coma Recovery Scale-Revised (CRS-R). The results showed that the peak amplitudes of MMN elicited by both large and small deviant stimuli were significantly different from baseline. In terms of the spatial properties of MMN, a significant interaction effect between conditions (small and large deviant stimuli) and electrode nodes was centered at the frontocentral area. Furthermore, correlation coefficients were calculated between MMN amplitudes and CRS-R scores for each electrode among all participants to generate topographic maps. Meanwhile, a significant negative correlation between the MMN amplitudes elicited by large deviant stimuli and the CRS-R scores was also found at the frontocentral area. In consequence, our results combine the above spatial properties of MMN in patients with DOCs, and provide a more precise location (frontocentral area) at which to evaluate the correlation between clinical electrophysiological assessment and the level of consciousness.

Misreporting rate and influencing factors regarding the routes of transmission among reported HIV patients in Yili Kazakh Autonomous Prefecture of Xinjiang Uygur Autonomous Region of China / 中华流行病学杂志

Objective To understand the misreporting rate regarding the routes of transmission among the reported HIV patients in Yili prefecture of Xinjiang,since 2011.Methods An investigation focusing on the route of transmission among people living with HIV/AIDS was carried out to clarify the responsible reasons for the situation.Results The overall incorrect reporting rate on the route of transmission was 10.8％.The proportion of heterosexual transmission route was over estimated by 63.8％ to 72.0％.However,the proportion of injecting drug was underestimated by 27.5％ to 22.2％.The number of cases being confirmed as through heterosexual transmission but incorrectly reported was quite high,contributing 82.6％ of all the incorrectly reported cases.Most of the patients that incorrect reported,were moved from injecting drug use to heterosexual transmission,which contributed 79.5％ of all the total incorrectly reported cases.Results from multi-factor analysis showed that the risk related to incorrect reporting was 3.64 times in males than in females.People who anticipated to receive HIV testing were 2.23 times more than those who had not.Old-age groups were 3.511,4.053,4.415 and 6.524 times higher than those people who were aged below 16 years.Conclusions The proportion of heterosexual transmission route was over-estimated while the proportion on injecting drug use was underestimated.However,the transmission pattern had changed from injecting drug use at the early epidemic stage,to current sexual transmission mode.We recommended that more attentions should be paid to patients who were males,at older age or those who had no expectation in receiving the HIV testing,during the initial following-up stage.

Effect of protoscolex on T subsets in mice spleen cells in vitro / 中国免疫学杂志

Objective:To observe the effect of protoscolex on Th subsets and correlative cytokine in mice spleen cells in vitro.Methods:Co-culture spleen cells from BALB/c mice with protoscolices,then IL-4,IFN-γand TGF-βproduction in cell culture supernatants were analyzed by ELISA.The percentage of Th subsets were detected by Flow Cytometry analysis.Results:Secretion levels of IL-4 and TGF-βwere significantly increased in spleen cells at different time point in co-culture system with protoscolices.Ratios of Th2 and Treg cells were also significantly increased in co-culture system at different time points than the control groups.However,there was no statistical significance for ratio of Th1 cells at different time points.Conclusion:The protoscolex can increase the ratios of Th2 cells and Treg cells from spleen cells.Secretion levels of IL-4 and TGF-βwere also increased in spleen cells co-cultured with protosco-lices.The results suggest that these Th cell subsets play a role in the immune escape of the hydatid disease.

Construction of In Vivo Fluorescent Imaging of Echinococcus granulosus in a Mouse Model

Human hydatid disease (cystic echinococcosis, CE) is a chronic parasitic infection caused by the larval stage of the cestode Echinococcus granulosus. As the disease mainly affects the liver, approximately 70% of all identified CE cases are detected in this organ. Optical molecular imaging (OMI), a noninvasive imaging technique, has never been used in vivo with the specific molecular markers of CE. Thus, we aimed to construct an in vivo fluorescent imaging mouse model of CE to locate and quantify the presence of the parasites within the liver noninvasively. Drug-treated protoscolices were monitored after marking by JC-1 dye in in vitro and in vivo studies. This work describes for the first time the successful construction of an in vivo model of E. granulosus in a small living experimental animal to achieve dynamic monitoring and observation of multiple time points of the infection course. Using this model, we quantified and analyzed labeled protoscolices based on the intensities of their red and green fluorescence. Interestingly, the ratio of red to green fluorescence intensity not only revealed the location of protoscolices but also determined the viability of the parasites in vivo and in vivo tests. The noninvasive imaging model proposed in this work will be further studied for long-term detection and observation and may potentially be widely utilized in susceptibility testing and therapeutic effect evaluation.

A Rapid and Convenient Method for in Vivo Fluorescent Imaging of Protoscolices of Echinococcus multilocularis

Human and animal alveolar echinococcosis (AE) are important helminth infections endemic in wide areas of the Northern hemisphere. Monitoring Echinococcus multilocularis viability and spread using real-time fluorescent imaging in vivo provides a fast method to evaluate the load of parasite. Here, we generated a kind of fluorescent protoscolices in vivo imaging model and utilized this model to assess the activity against E. multilocularis protoscolices of metformin (Met). Results indicated that JC-1 tagged E. multilocularis can be reliably and confidently used to monitor protoscolices in vitro and in vivo. The availability of this transient in vivo fluorescent imaging of E. multilocularis protoscolices constitutes an important step toward the long term bio-imaging research of the AE-infected mouse models. In addition, this will be of great interest for further research on infection strategies and development of drugs and vaccines against E. multilocularis and other cestodes.

For ego-identity, Uyghur MSM were less positive than Han MSM (OR (95%CI) was 0.43 (0.32-0.58) ) ; those who were over 20 years of age when accepting their sexual orientation were less positive than those who were younger than 20 years of age when accepting their sexual orientation (OR (95%CI) was 0.61 (0.47-0.80) );and homosexuals were more positive than bisexuals (OR (95%CI) was 1.98 (1.50-2.61) ). For social-identity, Hui MSM were less positive than Han MSM (OR (95%CI) was 0.61 (0.42-0.88) ); those whose education level was higher than college were less positive than those with junior high education (OR (95%CI) was 0.60 (0.40-0.89) ); famers/herdsmen were more positive than students (OR (95%CI) was 4.17 (2.13-8.17) ); the divorced/widowed were more positive than the singles (OR (95%CI) was 2.40 (1.34-4.29) ); those who were over 20 years of age when accepting their sexual orientation were less positive than those who were younger than 20 years of age when accepting their sexual orientation (OR (95%CI) was 0.59 (0.44-0.81) ). Among the MSM with negative ego-identity and negative social-identity, the proportion of planning to get married with women was 66.8% (267/400) and 76.5% (306/400), respectively, which were higher than those with positive ego-identity (33.2% (133/400)) and positive social-identity (23.5% (94/400)) ; their proportion of intending to have offspring was 62.0% (287/463) and 73.4% (340/463), respectively, which were higher than those with positive ego-identity and social-identity (38.0% (176/463), 26.6% (123/463)) (χ(2) = 39.61 and 7.90, respectively, both P values were <0.05). Among the MSM with negative social-identity, the proportion of looking for male sexual partners in toilets or parks was 18.1% (188/1 040), in bathhouse or sauna was 17.3% (180/1 040), and through internet was 82.0% (853/1 040), which were higher than those with positive social-identity (8.9% (38/427), 9.8% (42/427) and 61.6% (263/427)) (χ(2) = 66.78, P < 0.01).</p><p><b>CONCLUSION</b>In 2013, the gay identity of MSM in Xinjiang was relatively poor, and the factors associated with it included ethnicity, occupation, marital status and education level. The MSM with negative identity tended to involve in risk sexual behaviors, and had increased risk of HIV infection.</p>

Genetic polymorphism of D16S539, D7S820 and D13S317 loci in the Kazak ethnic population / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To analyze the genetic polymorphism of D16S539, D7S820 and D13S317 in Chinese Kazak ethnic population from Xinjiang.</p><p><b>METHODS</b>One hundred and two unrelated individuals and a sample of families (n=42) were investigated by multiplex amplification, 6% denaturing PAGE and silver staining. And, the obtained allele frequencies were compared with those of other populations.</p><p><b>RESULTS</b>Eight, seven, eight alleles were observed at the 3 STR loci respectively and the genotypes distributions were in accordance with Hardy-Weinberg equilibrium. The expected heterozygosities for these loci were 0.9439, 0.9356 and 0.9304; the calculated polymorphism formation content (PIC) was 0.9905; the discrimination power (DP), 0.9998; the paternity exclusion (PE), 0.9572. In addition, significant difference was found in comparison with other populations, and in the sample of families (n=42) no new mutations could be found.</p><p><b>CONCLUSION</b>The multiplex examination of 3 STR loci can be used in forensic identification and population genetics research.</p>
