Chinese Journal of Biologicals 2023;36(11):1319-1323
Objective To evaluate the stability of human immunoglobulin(pH 4)for intravenous injection(IGIV)after process optimization.Methods A filter plate and B filter membrane were used to filter the protein components in different separation stages to reduce the residue of immunoglobulin A(IgA)in the product in multi-batch large-scale production. The finished product was examined for the physical properties(appearance,visible foreign body,insoluble particle examination and thermal stability test)and the chemical properties[protein content,purity,molecular size distribution,titers of antiHBs,diphtheria antibody,prokallikrein activator(PKA),anti-complement activity(ACA),anti-A and anti-B hemagglutinin,and IgA residue]. The accelerated and long-term stability tests were performed.Results There was no significant difference in the key quality indicators between IGIV batches produced by the optimized process and the normal process,while the IgA residue decreased significantly(t = 3. 992 and 11. 215 respectively,each P < 0. 05). In the accelerated stability and long-term stability tests,all the test results of IGIV after process optimization were qualified,which met the relevant regulations in the third part of Chinese Pharmacopoeia(2020 edition).Conclusion IGIV after process optimization can effectively reduce IgA residue with good stability,which is of great significance for blood product manufacturers to improve the quality of IGIV products.
2.Treatment and prognosis of middle cerebral artery stenosis
International Journal of Cerebrovascular Diseases 2014;22(1):57-61
Intracranial arterial stenosis is the most common vascular lesions in patients with acute stroke in Chinese population,and most of them are middle cerebral artery (MCA) stenosis.The treatment of asymptomatic MCA stenosis is mainly to control the risk factors and treat with drugs,and the prognosis is better.Statins can reduce new stroke events.The treatment programs of symptomatic MCA stenosis are mainly to control the risk factors,treat with drugs and stenting.Now it is considered that anticoagulants are not superior to antiplatelet drugs in the treatment of MCA stenosis,but whether dual antiplatelet drugs are superior to monotherapy and stenting remains to be determined.The prognosis of symptomatic MCA stenosis is poor.The prognosis of acute phase mainly depends upon imaging features,and the risk of recurrent stroke is primarily associated with the MCA stenosis.Future research should focus on whether dual antiplatelet therapy is superior to monotherapy,and whether stenting is superior to drug treatment,as well as the relationship between the degree of MCA stenosis and prognosis of acute phase or the risk of recurrent stroke.

Chinese Journal of Rehabilitation Theory and Practice 2010;16(5):421-422
The rehabilitation exercise has been found to be an important part of the treatment of the senior coronary heart disease in the recent researches. The senior patients with coronary heart disease are always complicated, so the exercises should start with low intensity and increase gradually. It is important to pay attention to the warm up and relaxation before and after the exercises. There are few patients accepted rehabilitation, which need pay more attention on it to help the senior patients improve their quality of life.
