Chinese Journal of Biologicals 2024;37(2):245-250
Lactoferrin(LF),as a kind of iron-bound natural transferrin with wide functions,has become a research hotspot at home and abroad in recent years. Studies have shown that LF has a wide range of treatment,prevention and biological activity. This paper reviewed the clinical effects of LF in immune regulation,anti-tumor,regulation of obesity mechanism,antibacterial,anti-Alzheimer disease(AD)and bone regeneration mechanism in recent years,in order to provide a direction for the follow-up clinical application and research of LF.
2.Selection of the treatment strategies of myelodysplastic syndromes based on clone category
Journal of Leukemia & Lymphoma 2011;20(12):759-762
Myelodysplastic syndromes(MDS) are heterogeneous clonal stem cell disorders.There are about 40 %-60 % MDS patients with abnormal karyotype.To analyze the clone category is not only useful for diagnosis and evaluating prognosis,but also helpful for the selection of optimal therapy strategies to improve the treatment efficacy.
3.Treatment focused on myelodysplastic syndromes based on cytogenetic categories
Journal of Leukemia & Lymphoma 2010;19(5):262-264
Myelodysplastic syndromes (MDS) are heterogeneous clonal stem cell disorders characterised not only by peripheral cytopenia and bone marrow hyperplasia but also by karyotype. The course of disease, clinical outcome and response to treatment. Cytogenetic categories is a pattern typing the intrinsical features of MDS. It is suggested here that investigating biological characters and group treatment in MDS based on cytogenetic categories may enhance the therapeutic effect and bring benefit to MDS patients.

Journal of Third Military Medical University 2002;0(12):-
Objective To explore the expressions of cardiac protein kinase C(PKC),IGF-1(insulin-like growth factor 1) and the effect of drugs in the process of left ventricular remodeling(LVRM).Methods SD rats were randomly divided into four groups: sham operation group,infracted group,Captopril group and Valsartan group.Except for sham operation group,left anterior descending coronary artery was ligated in all rats of the other three groups and the intragastric administration of solvent,100 mg?kg~(-1)?d~(-1) Captopril and 20 mg?kg~(-1)?d~(-1) Valsartan was done on day 3 after operation for 8 weeks,then LVRM was evaluated by pathologic analysis.Expression changes of cardiac AgT_(1)R,PKC,and IGF-1 were detected by immunohistochemistry and computer image analysis.IGF-1 mRNA expression was analyzed by RT-PCR.Results LVW,LVWI and the expressions of AgT_(1)R,PKC,IGF-1 mRNA and proteins were significantly enhanced(P

Infectious factors contribute to human cancers.In past few years,chlamydia,hepatitis C virus (HCV)and helicobacter pylori (HP)had been found in the mucosa-associated lymphoid tissue (MALT)lymphomas of ocular adnexa.The infectious factors had been considered to be associated with the oncogenesis,management and treatment of tumor.Antibiotic therapy against infectious factors may herald a future with a curtailed role for traditional therapies of surgery,radiation,and chemotherapy.Unlike MALT lymphoma of gastric related to a single infectious factor,multiple organisms may play a role in the etiology in MALT lymphoma of ocular adnexa.MALT lymphoma of ocular adnexa is seldom in clinic.The characteristics of MALT lymphoma of ocular adnexa,the relationship of MALT lymphoma of ocular adnexa and causal agents are reviewed.

Objective:To observe the clinical effect of moxibustion on Governor Vessel for ankylosing spondylitis (AS) due to kidney yang deficiency.
Methods:A total of 60 patients of AS due to kidney yang deficiency were randomly divided into a treatment group and a control group by random digital table, 30 cases in each group. Both of the two groups were treated by oral administration of Sulfasalazine tablets. Additionally, the treatment group was given moxibustion on Governor Vessel, and the control group was given sham moxibustion. The treatment was given once every other day, 4 weeks constituted one course, 2 courses in total. Before treatment, after 1-course and 2-course treatments, the quantified scores of traditional Chinese medicine (TCM) syndromes and the symptoms scores recommended by AS International Society [including Bath ankylosing spondylitis disease activity index (BASDAI), visual analogue scale (VAS), Bath ankylosing spondylitis functional index (BASFI) and Bath ankylosing spondylitis metrology index (BASMI)] were respectively observed and recorded, and the change of safety item was monitored.
Results:After 1-course and 2-course treatments, the quantified scores of TCM syndromes were obviously improved than those before treatment in the two groups (P<0.05), and the score was improved better in the treatment group than that in the control group (P<0.05). In comparison within the group, there were no statistical differences between the scores after 1-course treatment and 2-course treatment in the two groups (P>0.05). After 1-course treatment, the items of the symptoms scores were improved than those before treatment in the two groups (P<0.05). After 2-course treatment, the therapeutic effect was more remarkable in the treatment group, with a statistical difference between the two groups (P<0.05). During treatment, no obvious abnormality in all safety items was noticed in the two groups.
Conclusion:Moxibustion on Governor Vessel can effectively relieve the clinical symptoms of AS patients, without obvious adverse reaction.

Objective To analyze the causes and explore suitable treatments for the complica-tions induced by polyacrylamide hydrogel (PAHG) injection for augmentation rhinoplasty. Methods The causes of the complications of 52 cases who accepted PAHG injection for augmentation rhinoplas-ty were analyzed and summarized. All the patients were treated by surgical operations to remove the injected PAHG. Results The complications included infection, granuloma, skin ulceration, bad shape, pain and serious psychological stress. Each case had 1 to 4 complications. Satisfactory results were obtained after suitable treatments. Some cases had silicone or expanded polytetrafluoroethylene implant augmentation rhinoplasty at the same time or secondary to the PAHG removal. A few cases had sequelae and long time psychological stress or tend pain of nose. Conclusions The complications induced by PAHG injection for augmentation rhinoplasty are various, and may relate to the inherent character of PAHG and the anatomic features of the nasal soft tissue. Surgery can remove the PAHG as completely as possible, which is a better method to treat the complications of PAHG injection for augmentation rhinoplasty.

BACKGROUND: Wnt signaling pathway is a key regulator of cellular proliferation and differentiation, but its correlation with neural differentiation of bone marrow mesenchymal stem cells (BMSCs) is not very clear. OBJECTIVE: To find out the molecules of the Wnt family which are involved in differentiation of rat BMSCs into neuron-like cells. METHODS: The rat BMSCs were separated and cultured in vitro. The morphology of the BMSCs was observed. Flow cytometry analysis was performed to detect cell phenotype CD44, CD9, CD34 and CD45. Wnt3a and Wnt5a were respectively combined with basic fibroblast growth factor to induce BMSCs differentiation into neuron-like cells, and then were identified by using immunocytochemistry and RT-PCR. RESULTS AND CONCLUSION: The BMSCs were long-spindle. CD9 and CD44 were highly expressed, while CD34 and CD45 were lowly expressed. Nestin and neuron specific enolase were positive but glial fibrillary acidic protein were not obviously expressed when they were cultured with Wnt3a. In Wnt5a group, Nestin expression was weakly positive, while neuron specific enolase and glial fibrillary acidic protein were negative. RT-PCR result revealed Nestin expressed both before and after induction in the Wnt3a induced group, neuron-specific enolase exhibited apparent amplified bands 5 days after the induction, and more apparent at 10 days. A weak amplification band of glial fibrillary acidic protein could be seen at 10 days after the induction. In Wnt5a and control groups, BMSCs induced by 10 days weakly expressed Nestin, while neuron-specific enolase and glial fibrillary acidic protein were almost not expressed. It is indicated that Wnt3a molecule can promote the differentiation of BMSCs cultured in vitro to neuron-like cells.
