Objective To investigate the changes and clinical indications of interleukin-2 receptor, ferritin and fi-brinectin in the cerebrospinal fluid of central nervous system leukemia.Methods ELISA was used to detect the changes of-soluble interleukin-2 receptor, ferritin and fibrinectin in the cerebrospinal fluid of central nervous system leukemia group ( CNSL) and non-CNSL group.Results The concentrations of soluble interleukin-2 receptor, ferritin and fibronectin ince-rebrospinal fluid of the CNSL group were significantly higher than those in non -CNSL group and the control group ( p <0.05).Conclusion The soluble interleukin 2 receptor, ferritin and fibronectin in cerebrospinal fluid are indicative of cen-tral nervous system leukemia.The result suggests that combined detection is important in early diagnosis of central nervous system leukemia.

Objective:To investigate the mutation of Brg1 gene and expression of Brg1 protein in gastric adenocarcinoma,and to study its relation with tumor development.Methods:By means of polymerase chain reaction-single strand conform action polymorphism(PCR-SSCP)37 cases of gastric mucosa were searched for Brg1 gene mutation in exon 4 and 16.By immunohistochemistry the expression of Brg1 protein in 30 cases of gastric adenocarcinoma was analyzed for their role in gastric cancer development and prognosis.Results:In 37 cases of gastric adenocarcinoma,no mutation of Brg1 gene was detected.Brg1 protein expression was 76.67% in gastric carcinoma which was higher than that in normal tissue(44.44%.) The expression of Brg1 was related to tumor growth,lymphnode metastasis and tumor differentiation.Conclusion:Genetic abnormalities of Brg1 might be rare and might not play a major role in stomach carcinogeneses.An increased expression of Brg1 protein was associated with the advanced stage of gastric carcinoma,the Brg1 expression can be used as an important indicator for differentiating malignancy and prognosis of gastric carcinoma.

To compare the efficacy and adverse effects of bortezomib+cyclophosphamide+dexamethasone (PCD) and vincristine+adriamycin+dexamethasone (VAD) regimens in multiple myeloma (MM). Methods:A total of 41 patients with MM were analyzed retrospectively and divided into two groups according to their treatment protocols:PCD group (21 cases) and VAD group (20 cases). Clinical effects and adverse effects were observed in both groups. Patients accepted two to four cycles of PCD or VAD regi-mens. Results:In the PCD group, three patients achieved complete remission (CR), three patients had very good partial remission (VG-PR), three patients were under partial remission (PR), eight patients had stable disease status (SD), and four patients had progressive dis-ease (PD). In the VAD group, none achieved CR, one patient had VGPR, two patients were under PR, nine patients had SD status, and nine patients had PD. The rate of patients who achieved efficacy (CR+VGPR+PR) in the PCD group was 42.9%, which was higher than that of the VAD group (15.0%). The rate of newly diagnosed patients who achieved good efficacy (CR+VGPR) in the PCD group was 50%, which was higher than that of the VAD group (7.7%). The incidence of herpes infection, cytopenia, fatigue, and gastrointestinal symptoms was similar in the two groups, whereas the incidence of neurotoxicity in the PCD group was higher than that of the VAD group. Conclusion:The response rate of PCD is higher compared with that of conventional VAD chemotherapy, especially in newly di-agnosed MM. PCD may improve CR and VGPR rates and may bring about more severe toxicities, such as neuropathy.

This paper summarized the application of Female Sexual Function Index (FSFI), and introduced its scoring system.

Objective To compare the results difference between the fluorescence staining and the acid fast staining (Ziehi‐Neelsen staining) methods in the detection of Mycobacterium tuberculosis ,and to compare the effects of the methylene blue solu‐tion ,Haris hematoxylin solution and potassium permanganate liquid as the redyeing reagents of the fluorescence staining method . Methods 198 sputum specimens collected from the patients with suspected tuberculosis symptoms and were performed the Ziehi‐Neelsen staining and the fluorescence staining respectively For comparing the difference in the detecting rate of Mycobacterium tu‐berculosis between the two kinds of method .The fluorescence staining adopted 0 .3% methylene blue solution ,0 .5% Haris hema‐toxylin solution and 0 .5% potassium permanganate solution as the redyeing reagents for comparing the effects of the fluorescence microscopic examination among different redying reagents .Results The detection rate of Mycobacterium tuberculosis was 66 .67%(132/198) for the Ziehi‐Neelsen staining ,94 .9% (188/198) for the fluorescence stainings and 94 .95% (188/198) for the methyl‐ene blue staining ,in which the detection rate of methylene blue redyeing was 94 .95% ,which of hematoxylin redyeing was 94 .44%(187/198) and which of potassium permanganate redyeing was 94 .44 (187/198) ,the differences among them were statistically sig‐nificant(P< 0 .05) .Conclusion The fluorescent staining method has the higher positive detection rate of Mycobacterium tubercu‐losis than the Ziehl‐Neelsen staining method ,in which 0 .3% methylene blue solution is a good background quenching redyeing solu‐tion .

Objective:To analyze the clinical application of Bozhi glycopeptides to provide reference for its rational use in clinics . Methods:The related literatures of Bozhi glycopeptides from the databases of CNKI , Wanfang and VIP were retrieved .The main clinical application ( the number of literatures on the same disease entities was above 3) and ADR were analyzed and evaluated .Results:A total of 163 literatures were found, including 137 clinical application and 11 ADR case reports.The disease with the number of literatures a-bove 3 included condyloma acuminatum (9 literatures), herpes zoster (6 literatures), hand-foot-mouth disease (6 literatures), psoriasis vulgaris (6 literatures), lung cancer (5 literatures), repeated respiratory infection (4 literatures) and hepatitis B (9 literatures), and the total number was 45.Among them, 32 literatures (1 772 cases) involved ADR, and 49 cases (2.77%) of ADR were reported, and the main performance was skin and its appendages damage (10 cases, 20.0%).Totally 11 ADR case reports mainly involved rigors and fever (13 cases, 37.2%).Conclusion:Bozhi glycopeptides as an adjuvant drug is mainly combined with other drugs to enhance the effi -cacy of mian drugs in clinical application , which shows low incidence of ADR mainly including skin and its appendages damage .

Objective To compare therapeutic effect of single hemoperfusion and hemoperfusion combined with continuous veno-venous hemofiltration ( sequential continuous blood purification) on patients with severe acute organophosphate poisoning combined with myocardial injury.Methods A total of 80 patients with severe acute organophosphate poisoning combined with myocardial injury admitted to EICU of Beijing Chaoyang Hospital from Jan.2004 to Dec.2013 were respectively analyzed and divided into two groups: hemoperfusion group (patients collected from Jan.2004 to Dec.2008, n=41) and sequential continuous blood purification (patients collected from Jan.2009 to Dec.2013, n =39).The average cholinesterase recovery time, the average consciousness recovery time, the average doses of atropine, the average hospital time, the change of cardiac troponin I levels on days 1, 2, 3, 5 and 7 after admission, and the change of left ventricular ejection fraction within 24 h after admission and after 24 h following blood purification treatment were compared between the two groups.Results Patients in the sequential continuous blood purification group had less average cholinesterase recovery time, average consciousness recovery time, average doses of atropine and average hospital time compared with patients in the hemoperfusion group [ ( 87.6 ±8.8 ) h vs.( 113.8 ±13.3 ) h;(57.3 ±11.7) h vs.(100.5 ±10.8) h;(284.5 ±61.4) mg vs.(476.6 ±93.1) mg and (10.2 ±2.3) vs. (14.6 ±3.9) , all P<0.01].The levels of cardiac troponin I on days 2, 3, 5 and 7, and ejection fraction of left ventricule after 24 h following blood purification treatment in the sequential continuous blood purification group were significantly decreased compared with patients in the hemoperfusion group ( all P <0.05 ) . Conclusion Therapeutic effect of sequential continuous blood purification on patients with severe acute organophosphate poisoning combined with myocardial injury is superior to single hemoperfusion.It suggests that sequential continuous blood purification could be used as a preferred choice in treatment of patients with severe acute organophosphate poisoning combined with myocardial injury.
