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.

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.

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.

Objective To establish Phage Amplified Biologically Assay (PhaB) detecting isoniazid(INH) resistance rapidly and evaluate PhaB assay for drug susceptibility testing of isoniazid(INH) in clinical isolates of Mycobacterium tuberculosis(MTB). Methods Detecting the INH resistance of 167 clinical isolates of MTB by PhaB assay,comparing the results of PhaB with that of Bactec-960 system and analyzing the sensitivity, specificity and accuracy of PhaB assay. Results When the mixture of 0.2 ?g /ml INH and MTB was incubated in 37℃ for 48 h, the accurate results were obtained rapidly by calculate the reduce of plaque of PhaB assay. If the results of Bactec-960 system is the golden standard, the sensitivity, specificity, PPV, NPV and accuracy of PhaB assay was 96.4%, 96.4%, 93.1%, 98.2% and 96.4% respectively. Conclusions The PhaB assay with highly sensitivity specificity are highly consistent with Bactec-960 system. Not only it takes only three days to detect drug susceptibility of INH in clinical isolates of MTB but also it is easily to operate. We believe that this low-cost assay may be a good rapid screening of INH resistance in MTB isolates.

Objective Evaluating possibility of phage amplified biologically(PhaB) assay in detecting susceptibility of Mycobacterium tuberculosis(MTB) to four first-anti-tuberculosis-drugs on the same time and of 139 clinical isolates to streptomycin(S), isoniazid(H), rifampin(R) and ethambatal(E) at the same time, comparing with the results of Bactec-960 and determining the minimal inhibitory concentrations(MIC) of isolates which results were not consistent. Results Concordance rates of the susceptibility to S, H, R and E in 139 clinical isolates detected by PhaB and Bactec-960 are 97.1%, 99.3%, 95.7% and 95.0% respectively. If the results of Bactec-960 system is the golden standard, the sensitivity, specificity, positive and negative predictive value (PPV and NPV) as well as accuracy of susceptibility test to S detected by PhaB assay was 90.0%, 99.1%, 96.4%, 98.2% and 97.1% respectively, to H 97.9%, 98.9%, 97.9%, 98.9% and 95.0% , to R 86.2%, 97.3%, 89.3%, 96.4% and 95.0%, to E 81.0%, 97.5%, 85.0%, 96.6% and 95.0%. There are 19 inconsistent results of 13 isolates in comparing PhaB with Bactec-960. 18 results of 12 isolates by MIC are identical with the results of PhaB assay. 1 result of 1 isolate is identical with Bactec-960. Conclusions[KG1]The results of susceptibility to S, H, R and E detected by PhaB were highly concordance rate with the results of Bactec-960. PhaB assay can be used for rapid screening of susceptibility test for MTB.

Objective To establish a method for rapid determination of nitrate in air. Methods Nitrate in air was absorbed using Na2CO3-NaHCO3 solution and the content of nitrate in the absorption liquid was determined by ion chromatography. Results The detection limit of NO3- was 0.008 mg/m3 when the sampling volume of air was 100 L. The linear correlation coefficient was 0.999 6. The relative standard deviation of the method was less than 5% and the recovery rates was 92.0%-96.7%. Conclusion The method had good selectivity and was simple and rapid for the determination of nitrate in air.

50?10~(9)/L. Of the patients, 3 died of liver function exhaustion or disease relapse 1-12 months after transplantation , 2 are still alive with disease for 3-5 months , but others are still alive and disease-free for 3-64 months. Conclusions:PBSCT is a safe therapeutic option that can significantly improve in acute leukemia and malignant solid tumors.
