High-intensity focused ultrasound (HIFU) is a newly-developed noninvasive technique recently. Being a safe, non-radioactive and reproducible therapy, high-intensity focused ultrasound has been extensively used in the clinical treatment for a variety of solid tumors such as uterine adenomyosis. This paper aims to make a comprehensive review about this technique, focusing on the mechanism, clinical indications and contraindications, safety, efficacy and the complications of HIFU for the treatment of uterine adenomyosis.

Purpose:To study the effect of recombinated human granulocyte colony-stimulating factor (rhG-CSF,filgrastim) on leukopenia induced by chemotherapy.Methods:Ten cases of leukopenia of grade Ⅳ induced by chemotherapy of malignant tumor were treated with rhG-CSF . When WBC2.5?109/L, rhG-CSF was stopped.Results:All patients with leukopenia of grade Ⅳ recovered to normal after treatment with rhG-CSF , the average time of usage was 6.8 days. The infection rate was 60%(6/10). Conclusions:Filgrastim is effective in the treatment of leukopenia of grade Ⅳ after chemotherapy, rhG-CSF decreases infection and facilitates chemotherapy.

Fourteen critical patients were treated by total parenteral nutrition(TPN) or en- teral nutrition(EN) and good results were achieved.Among the1 4patients,1 0 cases were suffered from MSOF.The results suggest thatnutritional support is very im- portant for the critical patients,especially for their rehabilitation and prognosis.The use of TPN is not limited by the gastroin- testinal function.TPN should be sellected preferably when a patient is critical and se- rious.EN should be used when gastroin- testinal function have recovered in order to reduce the translocation of bacteria and en- dotoxin in the gut and decrease gastroin- testinal bleeding.

Kawasaki disease is an acute self-limiting systemic vasculitis syndrome and usually occurs in children.The small and medium arteries of the whole body are mainly invaded, and marked with coronary arteries.Coronary artery dilation and aneurysm formation mainly occur in the early period.Thrombi, intimal hyperplasia, and calcification could be formed during the later period.Consequently, sometimes, it develops intochronicischemic cardiopathy or myocardial infarction.In that, Kawasaki disease has become the leading cause of acquired heart disease for children in developed countries.Presently, the treatment of coronary artery lesions caused by Kawasaki disease includes drug therapy, and interventional and surgical treatment.However, medications usually fail to solve severe coronary conditions, and only interventional and surgical treatment can we choose.Therefore, the development and indications of interventional and surgical treatment of coronary artery lesions caused by Kawasaki disease were reviewed in this article.

Objective To explore the relationship between single nucleotide polymorphisms (rs12953-717) of SMAD7 and susceptibility of non-small cell lung cancer (NSCLC) in Chinese Han population.Methods A single nucleotide polymorphisms (rs12953717) from SMAD7 was detected via Sequenom system in 528 NSCLC cases and 762 healthy controls.Data was statistically analyzed by unconditional Logistic regression method.Results rs12953717 had significant differences between non-small cell lung cancer patients and the controls.Compared with CC/TT (CC combined with TT) genotype,the adjusted odds ratio for the CT genotype was 4.107 (95％ CI:3.206 ～ 5.260,P =0.000 1).Smokers had a 2.004 odds ratio (95 ％ CI =1.583 ～ 2.537,P =0.000 1) of NSCLC compared with the controls.There was a 10.074-fold increased risk of NSCLC among the subjects with CT genotype and smokers.Conclusion The polymorphism of rs12953717 may have relation with risk of NSCLC.Heterozygote (CT) is a susceptibility genotype of NSCLC.Smoking is one of the risk factors of NSCLC.Smoking and CT genotype have synergistic effects on NSCLC susceptibility.

Aim To investigate the effect on antagonism of benthiactzine and atropine against the function of muscarinic acetylcholine receptors by desensitization of nicotinic acetylcholine receptors. Methods The whole cell recording configuration of patch-clamp technique was used and the cell model was rat SCG neurons. To identify antagonists' antimuscarinic effect, mAchRs mediated IM-inhibition was measured and nicotine and oxotremorine were used. Results After de sensitization of nAChRs,the antimuscarinic effect ofboth benthiactzine and atropine decreased compared to the normal condition. The decreased antimuscarinic effect of benthiactzine was weaker than that of atro-pine. The antimuscarinic effect of both benthiactzine and atropine recovered gradually with the recovery of nAChRs from desensitization. Conclusion Desensiti-zation of nAChRs weakens the antagonists' antimuscarinic effect.

Objective To investigate the efficacy of injectable osteoinductive material with fibrin sealant(FS) as a carrier compounded with bovine bone morphogenetic protein(bBMP) and bovine fibroblast growth factor(bFGF) for radial defect in dogs.Methods A total of 12 dogs were used in this study.The animals were randomly divided into treatment and control groups with 6 in each.We created a 20-mm bone defect at the upper radius of each dog,and then sutured the subcutaneous tissues and skin around the lesion.After the operation,FS(control) and FS+bFGF+bBMP were given to the two groups respectively by percutaneous injection.To compare the efficacy of the injections,we examined the animals by radiography in 4,8,16,and 24 weeks.The dogs were sacrificed in 24 weeks to obtain the specimens of the bone defect for histological examination and bone mineral density(BMD) determination.Results Radiography showed callus formation in 4 weeks and then osteoneogenesis in 24 weeks in the treatment group;whereas,in the control group,no callus was found around the defect in 24 weeks.In the treatment group,the mean BMD of the diseased radius was significantly higher than that of the healthy leg and that in the control group [(456.33?13.74) mg/cm2 vs(433.33?6.77) mg/cm2(t=2.57,P=0.00) and 0 mg/cm2].By histological examination,the new-formed bone in the treatment group was confirmed integral and dense with intact cortex and continuous marrow cavities in 24 weeks,while the bone defect of the controls were repaired with connective tissues without remodeling of the bone.Conclusion It is effective to repair bone defect in dogs by using injectable osteoinductive material with FS as a carrier compounded with bBMP and bFGF.

Objective To investigate the clinical and pathological characteristics as well as immunophenotypes of subcutaneous panniculitis-like T-cell lymphoma for its differential diagnosis with other similar diseases.MethodsThe clinical、histological and immunophenotypic features of 6 cases were described in detail and related literatures were reviewed.Results All of 6 patients presented with subcutaneous nodules or /and erythematous plaques without lymph nodes swelling and with 5 cases had fever,one case developed to ulcer from its nodules.All of 6 patient presented typical histological changes and 2 of them associated with prominent hemophagocytic syndrome.The neoplastic cells were of T-cell phenotype.Two patients under went an aggressive clinical course with short survival period of 9～16 months and four patients who treated with chemotherapy have an improved survival state,but two of them had recurrence.Conclusion SPTCL is a uncommon type of T-cell lymphoma with clinical and pathological characteristics,and it needs to be differentiated from benign panniculitis or other lymphomas of the skin.
