2.Lentivirus-based RNAi and its application in the study of T lymphocytes
Chinese Journal of Pathophysiology 2014;(10):1905-1909
The technique of lentivirus-based RNAi ( RNA interference) is a combination of the effective infec-tion and integrating characteristics of lentivirus vector and the specificity of RNAi to silence a homologous gene expression. It caused the post-transcriptional gene silencing ( PTGS) by a specific target sequence of mRNA degradation.As a kind of commonly used target cells in gene therapy, T lymphocytes play an important role in graft-versus-host disease ( GVHD) and other diseases.It is of great significance for increasing the infection efficiency of the target gene to T lymphocytes on this kind of disease for gene therapy.In this paper, we summarize the application of lentivirus-based RNAi in T lymphocytes.

The scientific research fund is an important resource for carrying out the scientific re-search projects effectively. Whether it can be reasonable used not only relates to the fulfilled quality, bene-fit, using direction and quantity, but also makes the reformation of management methods inevitable with the increase of quantities of the projects and funds. By summarizing the previously practical experiences, this paper explored the network managements of scientific research funds based on workflow in the hospital. By means of computer and network, the concept of workflow was further introduced to the application of platform of scientific research funds management. It embodies the charactor of approval flow in workflow management system. Finally the data of scientific research funds can be shared and integrated into multi-departments, so it is beneficial to improve the fund's benefit and strengthens the supervision in the whole process manage-ment.

Objeetive To investigate the effects of nimodipine combined with edaravone on cerebral vasospasm (CVS) and delayed cerebral ischemia (DCI) following aneurysmal subarachnoid hemorrhage (aSAH).Methods The consecutive patients with aSAH who underwent microsurgical clipping were included retrospectively.All patients received intravenous prophylaxis with nimodipine,and some patients also used edaravone (30 mg,twice a day for 2 weeks).They were divided into either a CVS group or a non-CVS group according to the findings of transcranial Doppler.They were also divided into a DCI group and a non-DCI group according to the findings of CT reexamination and clinical examination.The demographics,baseline clinical data,Glasgow Coma Scale (GCS) score,Fisher grade,Humt-Hess grade,and aneurysm location of all patients were collected.The multivariate logistics regression analysis was used to identify the independent risk factors for CVS and DCI.Results A total of 220 patients with aSAH were enrolled in the study,132 (60.0%) had CVS and 106 (48.2%) had DCI.One hundred twenty-three patients (55.9%)were treated with nimodipine + edaravone,97 were treated with nimodipine alone,none of them died.The incidences of CVS (51.2% vs.71.1%;x2 =8.962,P =0.003) and DCI (35.0% vs.65.0%;x2 =19.535,P <0.001) in patients receiving nimodipine + edaravone therapy were significantly lower than those receiving nimodipine alone.The proportions of hypertension,hyperlipidemia,diabetes,smoking,high Fisher grade in the CVS group were significantly higher than those in the non-CVS group (all P <0.05),while the proportion of patients receiving nimodipine + edaravone therapy (47.7% vs.68.2%;g2 =8.962,P =0.003) and the GCS score (11.2 ±3.1 vs.13.4 ±2.6;t =5.492,P<0.001) were significantly lower than those in the non-CVS group.Multivariate logistic regression analysis showed that low GCS score (odds ratio [OR] 6.57,95% confidence interval [CI] 1.04-12.96;P=0.001),high Fisher grade (OR 5.39,95% CI 4.09-20.15;P =0.004),hyperlipidemia (OR 4.39,95% CI 2.97-34.15;P =0.004),hypertension (OR 3.24,95% CI 1.06-13.47;P=0.016) were the independent risk factors for CVS,while received nimodipine + edaravone was the independent protective factor for CVS (OR 0.39,95% CI0.13-0.91;P =0.039).The proportions of patients with hypertension,hyperlipidemia,diabetes,smoking,and high Fisher grade in the DCI group were significantly higher than those in the non-DCI group (all P <0.05),while the proportion of patients received nimodipine + edaravone (40.6% vs.70.2%;x2 =19.535,P < 0.001) and the GCS score (10.2 ± 2.4 vs.13.8 ± 2.6;t =10.648,P < 0.001) were significantly lower.Multivariate logistic regression analysis showed that low GCS score (OR 8.92,95% CI 2.48-26.94;P =0.001),high Fisher grade (OR 7.49,95% CI 1.96-20.47;P =0.001) were the independent risk factors for DCI,while.received nimodipine +edaravone was an independent protective factor for DCI (OR 0.27,95% CI 0.08-0.97;P =0.020).Conclusions Compared with nimodipine alone,nimodipine combined with edaravone can significantly reduce the incidences of CVS and DCI.The GCS score,high Fisher grade,and hypertension are the independent risk factors for CVS and DCI in patients with aSAH,and nimodipine combined with edaravone is the independent protective factor for CVS and DCI.

Objective:To understand the laboratory characteristics for the diagnosis of immunoglobulin G4-related disease (IgG4-RD).Methods:The clinical data of 28 patients with IgG4-RD and renal damage (IgG4-RKD) diagnosed in our hospital from January 2017 to May 2019 were retrospectively analyzed. The correlation between serum IgG4 concentration and clinical features as well laboratory test results was analyzed. The 28 patients were divided into two groups: high serum IgG4 concentration group and normal serum IgG4 concentration group. The serum creatinine value, erythrocyte sedimentation rate, IgG concentration, IgA concentration, complement C3, C4 concentration, peripheral blood eosinophils, hemoglobin, IgG4/IgG and other related parameters were compared between the two groups. SPSS 20.0 statistical software was used for analysis. The two groups of measurement parameters were compared between groups by independent sample t test, non-normal measurement parameters were compared between groups by Mann-Whitney U test analysis, and the correlation between patients' IgG4 and each detection parameter was analyzed by Spearman correlation analysis. Results:Among the 28 patients, 17 were male and 11 were female, with an average age of (62±14) years. The serum IgG4 concentration increased in 75% of the patients ( n=21), with an average value of 3.01(1.41, 7.52) g/L, the serum IgG concentration increased in 64.3% of patients ( n=18), with an average value of 18.91 (12.88, 24.88) g/L, and the complement C3 decreased in 50% of the patients ( n=14), with an average value of(0.77±0.28) g/L. IgG4 was positively correlated with IgG ( r=0.422, P=0.025), IgG4/IgG ( r=0.951, P<0.01), ESR ( r=0.543, P<0.01) and peripheral blood eosinophils ( r=0.487, P<0.01), but negatively correlated with complement C3 ( r=-0.431, P=0.022) and C4 ( r=-0.504, P<0.01) levels. There were significant differences in IgG ( Z=-2.255, P=0.023), IgG4/IgG ( Z=-3.793, P<0.01), C3 ( t=7.380, P<0.01) and ESR ( t=-2.195, P=0.037) between the elevated IgG4 group and the normal group. Conclusion:Serological characteristics of IgG4-RKD combined with clinical manifestations may be able to diagnose IgG4-RKD in early stage.
