Hypoplastic myelodysplastic syndrome(Hypo-MDS),with the derangement of BM texture,is characterized by the hypoplasia of bone marrow(BM)accompanied with the deterioration of MDS. Hitherto there isn't a definite therapeutic definition about Hypo-MDS. Is therapy should be paid more attention to. This article introduces the study of therapy of Hypo-MDS.

BACKGROUND: Studies have showed that Chengzai pill is of distinct significance in the treatment of steroid-induced osteonecrosis of femoral head through increasing bone mineral density, bone weight, bone strength and rigidity, it also reverses the low levels of estrogen. OBJECTIVE: To explore the effect of Chengzai pill on the genes of cell adhesion molecules on bone cells of steroid-induced ostaonecrotic rats, and to understand the role to resume normal blood transport in femoral head of steroid-induced osteonecrosis. DESIGN, TIME AND SETTING: Grouping controlled observation was performed in the Pharmacological Laboratory of Wangjing Hospital of China Academy of Chinese Medical Sciences and laboratory of CapitalBio Corporation between March and August in 2006. MATERIALS: Six male SD rats of 6 months old and weighing (280:1:20) g were used in this study. Chengzai pill was consisted of 22 Chinese medicines, such as Chinese Angelica, Eucommia Bark, Milkvetch Root, Barbary Wolfberry Fruit, Degelatined Deer-hom, Desertliving Cistanche, Eupolyphaga seu Steleophaga, Leech, Danshen Root and Himalayan Teasel Root, which were offered by Beijing Boran Pharmaceutical Co., Ltd. METHODS: The lipopolysaccharide and methylprednisolone were applied to prepare a rat model of steroid-induced osteonecrosis of femoral head. Six rats were divided into model group and Chengzai pill group at random with 3 rats in each group. The rats in the Chengzai pill group were administrated with methylprednisolone for the first time and then 1.5 g/kg Chengzai pill solution, once a day, totally for 6 weeks. The total RNA was extracted from femoral head in all rata 6 weeks later and then gene expression profiling was analyzed. MAIN OUTCOME MEASURES: Gene action pathway of cell adhesion molecules in gene expression profile. RESULTS: Compared with model rats, there were totally 8 downregulated genes of cell adhesion molecules which changed by a minimum of 1.5 folds in cell adhesion molecules pathway of Chengzai pill group, three rats were present with 633 genes (506 down-regulated and 127 up-regulated), 883 genes (640 down-regulated and 243 up-regulated) and 593 genes (408 down-regulated and 185 up-regulated), respectively. MAS software classification analysis showed 79 action pathways were involved in 297 genes.CONCLUSION: Following Chengzai pill administration, those downregulated genes recover the cognitive functions of macrophage and target cell in rats, also renew the normal survival condition of epithelial cells including vascular endothelial cells. Cell adhesion molecules action pathway returns to normal levels. This is the key to resume normal blood transport in femoral head of steroid-induced osteonecrosis.

Objective To investigate the relationship between high-sensitive C-reactive protein(hsCRP)and insulin resistance(IR)in elderly hypertension patients.Methods The levels of ambulatory blood pressure mo- nitoring(ABPM),fasting plasma glucose(FPG),fasting insulin(FINS),von Willebrand factor(vWF),hsCRP were measured in elderly patients with hypertension alone(n=260),hypertension coexit with diabetes(n=230), and healthy matched subjects(n=250).Results The levels of FINS,FPG,vWF,hsCRP,systolic blood pres- sure(SBP),diastolic blood pressure(DBP)in the HT and HT+DM group were significantly higher than that in the NC group(P

Objective To establish normal reference intervals of plasma and urine neutrophil gelatinase-associated lipocalin (NGAL) in children′s hospital.Methods A total of 183 fresh EDTA anticoagulant samples and 125 fresh urine in healthy children were collected from May 2014 to October 2014.According to the CLSI C28-A2 ,the unilateral upper limit 95% was established the normal reference value in different age group.Results There was significant difference in four groups (P<0.05).The normal reference intervals of plasma NGAL in healthy children:0 to <7 months;<291.28 μg/L;7 months to <5 years old;<150.87 μg/L;5 years old to <9 years old:<127.93 μg/L;9 years old to ≤16 years old:<161.74 μg/L;the normal reference intervals of healthy children urine NGAL:0 to <7 months:<257.31 μg/L;7 months to <5 years old:<201.55 μg/L;5years old to <9 years old:<197.69 μg/L;9 years old to ≤16 years old:<151.46 μg/L.Plasma and urine NGAL results in neonatal group were higher than the other three groups.Conclusion The normal reference intervals of plasma and urine NGAL in children′s hospital is established.this could provide clinical evidence for the diagnosis and treatment of acute renal injury in pediatric patients.

Objective To investigate the value of contrast-enhanced ultrasonography(CEUS) for differential diagnosis of focal splenic solid lesions.Methods Thirty-two patients with 32 focal splenic lesions were examined with CEUS.The enhancement phases and perfusion were observed.Each group has 16 patients.Results The contrast media extincted more quickly in malignant lesions than in benign ones.The peak time and initial decreasing time of the malignant lesions were (19.7±4.5)s and (29.7±10.9)s.The opposite time of the benign lesions were (24.2±4.4)s and (50.9±22.8)s.The initial decreasing time of the malignant lesions was earlier than that of the benign ones.The enhancement pattern was similar between the two groups.More lesions can be detected after CEUS.The number of the lesions was 111 before CEUS and 142 after CEUS.Conclusions CEUS is useful in the differential diagnosis of splenic lesions.

Based on the characteristics of oncology clinical teaching and the defects of current teaching methods,we launched teaching reform including the combination of basic and clinical medical curriculum,the practice of clinical problem-based learning (CPBL) method and the introduction of some guidance for medical practice.The teaching reform was effective,but there were drawbacks for improvement.

Objective To observe the clinical effect on cervicogenic headache (CEH) of pulsed radiofrequency stimulation (PRF) applied to the C2 dorsal root ganglion combined with nerve block.Methods A total of 78 cases diagnosed as CEH were randomly divided into a combined treatment group,a PRF treatment group and a nerve block group.The combined treatment group was given both PRF applied to the C2 dorsal root ganglion and blocking therapy.The other two groups were given only one treatment or the other.All the treatments were once weekly for 3 weeks.Before treatment and 1,3 and 6 months after treatment,all of the patients' headaches were evaluated using a visual analogue scale (VAS).Results At 1,3 and 6 months after treatment,the average VAS scores of all three groups had decreased significantly.The VAS ratings dropped the most in the combined treatment group,followed by the PRF group and then the nerve block group.All the intergroup differences were statistically significant.The combined treatment group's cure rate (88％) was significantly better than that of the PRF group (81％),which was significantly better than that of the nerve block group (54％).Conclusion Combining PRF applied to the C2dorsal root ganglion with nerve block therapy has a synergistic effect on CEH.The curative effect of the combined treatment was better than either PRF or blocking alone.
