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.

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 explore the clinical effect of one new type of short section pedicle of vertebral arch nail system(internal fixation system by nail-stick) on patients with thoracolumbar fracture.Methods 68 patients with thoracolumbar fracture were selected.Internal fixation system by nail-stick was used on the patients with thoracolumbar fracture,the clinical effect was observed.Results After following up for six to eighteen months,the vertebral height was measured by X-ray.The anterior edge height of the vertebral was 47% before operation and 94% after operation,the posterior edge height of the vertebral was 76% before operation and 97% after operation,there was significant difference between preoperation and post operation(P<0.01).All the cases with AF intemal fixation system had better clinical effect,18 cases had satisfactory effect.Except that the neurological deficits of 4 cases had not been improved,those of the other cases all had been impreved at some degree.Conclusion Thoracolumbar fracture should be treated early,AF imtermal fixation system has significant effect on the thoracolumbar fracture,the skilled performance is important during the operation,and contraindications of internal fixation system by nail-stick should be noticed.
