In the recent years, with the improvement of conditioning regimens, the prevalence of high-resolution HLA matching, as well as the application of high-intensity broad-spectrum antibiotics, unrelated donor transplantation for the treatment of severe aplastic anemia has been improved significantly, with lower incidences of graft failure, graft-versus-host disease, infectious complications, etc. Studies have already confirmed that transplantation from an unrelated donor should be recommended as an effective therapy for children and young adults who do not respond to the first course of immunosuppressive therapy.

The growth and metastasis of tumor relies on oxygen and nutrients provided by neonatal blood vessel. When no angiogenesis, the tumor growth will be obviously inhibited. At present, anti-tumor angiogenesis strategies are increasingly becoming a focus of attention and study at home and abroad. However,because of the complexity of the antiangiogenesis, the clinical effects of antiangiogenesis alone is not so satisfied, while this is reversed when combined with radiotherapy.

There are many causes of children cerebral infarction, including cerebrovascular malformation,autoimmune cerebrovascular phlogistic, infection, trauma and the high state of blood coagulation. Because the brain development is not mature, the children is the high-risk group of traumatic cerebral infarction. The early diagnosis of traumatic cerebral infarctions relies on the dynamic performance of the clinical observation, taking head CT or MRI quickly, especially diffusion-weighted imaging, which is more sensitive on the judgement of acute cerebral infarction period. Common sites of traumatic cerebral infarction are basal ganglia. The infarcts are usually small. Treatment on traumatic cerebral infarction must give priority to non-operation. Early diagnosis and prompt treatment can provide better prognosis than adults.

OBJECTIVE:To investigate the effects of water extract of Panax quinque folium(WEAG,of cool property)and Panax ginseng(WERG,of warm property)on MPP+-induced apoptosis of SH-SY5Y cells.METHODS:SH-SY5Y cells were divided into 4 groups:the control group was cultured in complete medium,model group was cultured with 0.5 mmol MPP+;Panax quinque folium group was treated with 0.5 mmol MPP+ plus different concentration of WEAG,and Panax ginseng group was treated with 0.5 mmol MPP+ and different concentration of WERG concomitantly.WEAG and WERG were added for intervention.the morphology of SH-SY5Y cells was observed by Hoechst33258 staining and the apoptotic rate was detected by FCM;the cell survival rate was measured by MTT chromatometry.RESULTS:Compared with model group,WEAG and WERG markedly reversed the apoptotic characteristics of SH-SY5Y cells,markedly up-regulated MTT value and lowered the apoptotic rate,with WERG showing more potent efficacy than WEAG doing.CONCLUSION:Water extracts of both Panax quinque folium(cool)and Panax ginseng(warm)pose protective effects of different degree against MPP+-induced apoptosis of SH-SY5Y cells,with the Chinese materia medica of warm property showing more potent action against apoptosis.Chinese materia medicas of different drug property have different anti-apoptotic action.

OBJECTIVE:To investigate the effects of water extracts of Panax ginseng(warm),dry P.ginseng(mild),P.quinque folium(cool) on the apoptosis of SH-SY5Y cells induced by ?-amyloid protein(A?25-35).METHODS:SH-SY5Y cells were treated with A?25-35 to simulate the pathologic neuronic damage model in patients with Alzheimer's disease,and then treated with different doses of water extracts of P.ginseng(WERG),dry P.ginseng(WEG)or P.quinque folium(WEAG).The morphologic changes of the SH-SY5Y cells were observed by inverted microscope.Cell survival rate was measured by MTT assay.The percentage of apoptosis and the expression of Bax and Bcl-2 proteins were detected by Western Blotting.RESULTS: After treatment with A?25-35 50 ?mol?L-1 for 72 hours,SH-SY5Y cells became more round and aggregated and the cell survival rate was significantly reduced(P

The distribution of substance P-positive structure was studied in the human and rat spinal cord using immunohistochemical technique. The results showed that a very dense network of substance P-positive fibers was found in the spinal cord in laminae Ⅰ-Ⅲ, in Lissauer's fasciculus and a rather dense plexus was seen in the area around the central canal. P-positive fibesr were observed in the ventral horns, but they were rare. These positive fibers were stained yellow, brown and dark-brown colour. In addition, substance P-positive neuronal cell bodies and fibers were seen in rat spinal ganglia, and they were smaller cells.

This paper reports the methods of preparation of ?-BT-HRP conjugates. In the conditions of our laboratory we got this conjugate using the periodate method. Nevertheless, the conjugates were not able to be synthesized by the classical one-step and two-step glutaraldehyde methods. On the basis of these findings, we conclude that for the preparation of ?-BT-HRP the periodate method is very simple and effective

[Objective] To optimize the exact preparative technique of complex prescription Dragon’s Blood Plaster(DBP),to evaluate the therapeutic effect to endometriosis rats with acupoint therapy and to discuss its probable mechanism.[Methods] Making into DBP through the preparation of ultra-fine powder,extraction of the volatile oils and their ointments were made as well.Induced by surgery for the experimental endometriosis ,observed that the levels of PGF2a in the blood plasma and IL-1? in the blood serum in different control groups.[Results] Complex prescription DBP could inhibit the ectopic endometrium hyperplasic ,and decrease the levels of PGF2a.No significant difference in IL-1? in the blood serum.[Conclusion]The treatment by acupoint therapy with complex prescription DBP is effective to endometriosis.It could inhibit the ectopic endometrium hyperplasic and promote the shrinking of glands.
