Blood products are those biologicals derived from plasma or obtained by recombinant technologies. This overview covers the characteristics and classification of plasma proteins, the current status of products (albumin, immunoglobulins, coagulation factors and microcontent proteins), as well as the likely trends in the near future. Human serum albumin is one of the earliest, safest and most widely used proteins in the pharmaceutical field. The approval and development of high-purity plasma albumin, recombinant human albumin and HSA fusion proteins provide a favorable prospect for the therapeutic protein. Normal immunoglobulin contains antibodies to all the micro-organisms prevalent in the donor population. The IMIG is relatively simple to prepare and use, and the side effects are acceptable; IVIG is used mainly to treat patients with primary immunodeficiency syndromes; SCIG preparations can be used in selecting suitable patients for home therapy and have occurred fewer adverse systemic reactions; specific immunoglobulins contain concentrations of antibody to an individual organism or toxin at a higher titer than normal immunoglobulin and can not be replaced in clinical use. The plasma-derived or recombinant coagulation factors are used to treat the patients with congenital or acquired factor deficiency. The products such as Fibrinogen, FVII, FVIII, von Willebrand complex, FIX/PCC, FXI, FXIII and so on, have been widely used and proved to be effective. The development of recombinant FVIIa is now as a good bypassing product to haemophilia with inhibitors. The Fibrinogen and thrombin play a very important role in surgery hemostasis. Moreover, microcontent proteins including protein C, antithrombin, alpha 1-AT, tPA have been licensed and used in clinical treatment; a number of other small field proteins are under produced research or pre-clinical investment. The ongoing development of new recombinant plasma proteins is providing alternatives for patients, but the distinct position and the potential impact of plasma-derived preparations are unique, furthermore the development of new plasma protein is still a hot spot in global pharmaceutics. Nowadays, a relative difference exists in the development of blood products between our nation and developed countries, so the domestic manufacturers are faced with chances and challenges.

Conventional medical treatment for ulcerative colitis can have limited efficacy or severe adverse reactions requiring additional treatment or colectomy. Hence, different biological agents that target specific immunological pathways are being investigated for treating ulcerative colitis. Anti-tumor necrosis factor (TNF) agents were the first biologics to be used for treating inflammatory bowel disease. For example, infliximab and adalimumab, which are anti-TNF agents, are being used for treating ulcerative colitis. Recently, golimumab, another anti-TNF agent, and vedolizumab, an anti-adhesion therapy, have been approved for ulcerative colitis by the U.S. Food and Drug Administration. In addition, new medications such as tofacitinib, a Janus kinase inhibitor, and etrolizumab, another anti-adhesion therapy, are emerging as therapeutic agents. Therefore, there is a need for further studies to select appropriate patient groups for these biologics and to improve the outcomes of ulcerative colitis treatment through appropriate medical usage.

Neoadjuvant and adjuvant chemotherapies are used adjunctively with surgery or radiation and are among the treatment options that are now employed for reducing treatment failure in early-stage cervical cancers with high-risk prognostic factors. Adjuvant therapies have been reported to significantly improve survival than would otherwise be possible with surgery or radiotherapy alone. However, for advanced cervical cancers, sequential or concurrent chemo-radiotherapy does not appear to significantly increase survival. The combination of radiotherapy with IFN-a2a and RA in the treatment of patients with locally advanced cervical cancer showed high response rates, however this should be confirmed in larger studies. Recent reports show that postoperative adjuvant radiotherapy has no benefit in survival, but that postoperative adjuvant chemotherapy has improved survival. Toxicities and the optimum number of cycles of neoadjuvant and adjuvant chemotherapy, as well as biologic therapy, will follow along with individualized treatment based on high-risk prognostic factors. Although more comprehensive studies and longer follow up will be required for complete evaluation of these adjuvant therapies, preliminary results are promising.

Rheumatoid arthritis (RA) is a kind of chronic, progressive, multiple, invasive autoimmune disease with two chief cclinical manifestations arthrosynovitis and ex-arthrosis, easy to occur in middle-aged women, also occur in children and the elderly, is characterized by progressive and break out repeatedly. RA pathogenesis is complex, there is no special treatment, used in treatment of R drug varied, new drugs and new therapies also emerge in endlessly, main including non-steroidal anti-inflammatory drugs (NSAIDs), slow action anti-rheumatism medicine (SAARDs), glucocorticoids (GCs), biological agent, traditional Chinese medicine and traditional Chinese medicine preparations, domestic market for rheumatoid main drug treatment are NSAIDs, SAARDs, GCs, traditional Chinese medicine and traditional Chinese medicine preparations. Traditional Chinese medicine and traditional Chinese medi- cine preparations for the treatment of RA have its unique advantages, show the characteristics of overall adjustment, multi-level and multiple targets, and also can alleviate and against side effects of western medicine. In recent years, more and more get people's atten- tion. This paper reviewed the research progress and treatment features of commonly used therapeutic agents for the treatment of RA in recent years, which provides reference and basis for future medicine anti-RA.

Objective: To summarize the clinical characteristics of tumour necrosis factor receptor-associated periodic syndrome (TRAPS) in children. Methods: The clinical manifestations, laboratory tests, genetic testing and follow-up of 10 children with TRAPS from May 2011 to May 2021 in 6 hospitals in China were retrospectively analyzed. Results: Among the 10 patients with TRAPS, including 8 boys and 2 girls. The age of onset was 2 (1, 5) years, the age of diagnosis was (8±4) years, and the time from onset to diagnosis was 3 (1, 7) years. A total of 7 types of TNFRSF1A gene variants were detected, including 5 paternal variations, 1 maternal variation and 4 de novo variations. Six children had a family history of related diseases. Clinical manifestations included recurrent fever in 10 cases, rash in 4 cases, abdominal pain in 6 cases, joint involvement in 6 cases, periorbital edema in 1 case, and myalgia in 4 cases. Two patients had hematological system involvement. The erythrocyte sedimentation rate and C-reactive protein were significantly increased in 10 cases. All patients were negative for autoantibodies. In the course of treatment, 5 cases were treated with glucocorticoids, 7 cases with immunosuppressants, and 7 cases with biological agents. Conclusions: TRAPS is clinically characterized by recurrent fever accompanied by joint, gastrointestinal, skin, and muscle involvement. Inflammatory markers are elevated, and autoantibodies are mostly negative. Treatment mainly involves glucocorticoids, immunosuppressants, and biological agents.

Objective: To investigate the clinical characteristics of systemic juvenile idiopathic arthritis combined with coronary artery dilatation. Methods: A retrospective analysis was performed on the clinical data, including clinical manifestations, blood routine, inflammatory factors, echocardiography, vascular ultrasound and CT angiography, treatment and outcomes, etc, of 5 cases with systemic juvenile idiopathic arthritis combined with coronary artery dilation admitted to Department of Rheumatology in the affiliated Children's Hospital of Capital Institute of Pediatrics from May 2019 to June 2021. Results: There were 2 males and 3 females among 5 cases. The onset age ranged from 7 months to 4 years 7 months.The diagnostic time ranged from 1.5 months to 3.0 months.Four cases were diagnosed as atypical Kawasaki disease. Three cases showed unilateral coronary artery dilation.Two cases showed bilateral coronary artery dilation.Four cases developed multiple organ injuries.Three cases developed macrophage activation syndrome.Three cases developed lung injury.Two cases developed pericardial effusion.One case developed pulmonary hypertension.As for treatment, 3 cases treated with methylprednisolone pulse therapy and methotrexate combined with cyclosporine, improved after the final application of biological agents, and have stopped prednisone. The other 2 cases were treated with adequate oral prednisone and gradually reduced, and methotrexate was added at the same time, 1 case relapsed in the process of reduction. No other vascular involvement was found in 5 cases. Coronary artery dilation recovered completely after 1 to 3 months of treatment. Conclusions: Systemic juvenile idiopathic arthritis combined with coronary artery dilatation has the clinical characteristics of small onset age, long diagnostic time, prone to multiple organ injuries. Corticosteroids and conventional immunosuppressive agents are not sensitive, and biological agents should be used as soon as possible.The prognosis of coronary artery dilation is good after timely treatment.

Prediction of liver fibrosis progression has a key role in the management of chronic viral hepatitis, as it will be translated into the future risk of cirrhosis and its various complications including hepatocellular carcinoma. Both hepatitis B and C viruses mainly lead to fibrogenesis induced by chronic inflammation and a continuous wound healing response. At the same time direct and indirect profibrogenic responses are also elicited by the viral infection. There are a handful of well-established risk factors for fibrosis progression including older age, male gender, alcohol use, high viral load and co-infection with other viruses. Metabolic syndrome is an evolving risk factor of fibrosis progression. The new notion of regression of advanced fibrosis or even cirrhosis is now strongly supported various clinical studies. Even liver biopsy retains its important role in the assessment of fibrosis progression, various non-invasive assessments have been adopted widely because of their non-invasiveness, which facilitates serial applications in large cohorts of subjects. Transient elastography is one of the most validated tools which has both diagnostic and prognostic role. As there is no single perfect test for liver fibrosis assessment, algorithms combining the most validated noninvasive methods should be considered as initial screening tools.

Previous studies reported the beneficial effect of erythropoietin (EPO) in acute injuries. We followed patients with and without acute kidney injury (AKI) after coronary artery bypass grafting (CABG) and evaluated the effect of EPO on long-term outcome. We also assessed the efficacy of urinary neutrophil gelatinase-associated lipocalin (uNGAL) as a predictive marker of AKI. Seventy-one patients scheduled for elective CABG were randomly given either 300 U/kg of EPO or saline before CABG. The primary outcome was AKI, and the secondary outcome was the all-cause-mortality and composite of all-cause-mortality and end stage renal disease (ESRD). Twenty-one patients had AKI, 14 (66.7%) in the placebo group and 7 (33.3%) in the EPO group (P = 0.05). Also, uNGAL was higher in the patients with AKI than in those without AKI at baseline, 2, 4, 24, and 72 hr after CABG (P = 0.011). Among patients with AKI, 2-week creatinine (Cr) was not different from baseline Cr in the EPO group, but 2-week Cr was significantly higher than baseline Cr in the placebo group (P = 0.009). All-cause-mortality (P = 0.022) and the composite of all-cause-mortality and ESRD (P = 0.003) were reduced by EPO. EPO reduces all-cause-mortality and ESRD in patients with AKI, largely due to the beneficial effect of EPO on recovery after AKI.
