Objective To explore the clinical characteristics and diagnosis of mycoplasma pneumoniae(MP) pneumonia showing lobar pneumonia.Methods Patients from Jan.2004 to Dec.2005 were selected as researching case,which had samptoms and signs of respiratory in clinic,the chest Xray shown lobar pneumonia,the MP of down respiratory′s secretion detected by polymerase chain reaction(PCR) and MP-IgM of serum detected by indirect hemagglutination were positive.The clinical data of them were reviewed.Results MP pneumonia showing lobar pneumonia was same to streptococcus pneumoniae pneumonia in clinic,but it had some characters:1.majority of the lobar MP pneumonia were children being student;2.the process was long,the samptoms of respiratory was tipical,the continuous fever was few,and the infectious samptoms was not obvious as streptococcus pneumoniae pneumonia;3.the injury to lung was more and tipical;4.the increase of white blood cell,neutrocyte and C-reactive protein were not clearly as to streptococcus pneumoniae pneumonia,but the absorbing of lung′s focal was relatively fast;5.the ?-lactams antibiotic was not effective,but macrolides was effective.Conclusions Clinical characters of MP pneumonia are needed to master,the variety of chest X-ray changes and differentiate from other pneumonia infected by other are needed to notice.

ObjectiveTo investigate the serum soluble urokinase-type plasminogen activator (suPAR)in patients with multiple myeloma,its relationship with the 2-year survival rate and its clinical significance in predicting the disease prognosis.MethodsEnzyme-linked immunosorbent assay was applied to determine the levels of suPAR of 40 initial diagnosed patients with MM and 30 healthy persons as healthy control group.The patients were divided into three groups:effective (13 cases),remission (19 cases) and invalid (8 cases).ResultsUsually there was suPAR expression [(233.47±83.22) pg/ml] in serum of the healthy adults.There was no statistical difference of the suPAR expression in effective group or remission group before treated [(257.60±32.47) pg/ml,(331.00±99.80) pg/ml] compated with healthy group (t =2.04,t =1.83,P ＞ 0.05),and that in the invalid group,serum levels of suPAR [(562.20±291.0) pg/ml] was statistically significant with that of the effective group and that of the healthy control group (t =3.92,t =1.93,P ＜ 0.05).Through monitoring 17 patients,the suPAR of patients before treatment [(437.65±131.43) pg/ml] was statistically significant with that of healthy control group (P ＜0.01) and effective group after treatment [(298.76±108.59) pg/ml] (P ＜0.01).Serum suPAR of more than 2-year-survival patients [(333.02±85.37) pg/nl] during initial diagnosis was not statistically difference with that of the healthy control group (t =1.81,P ＞ 0.05).Serum suPAR of less than 2-year-survival patients [(646.01±103.97) pg/ml] was statistically different with that of healthy control group (t =3.84,P ＜0.01) and that of more than 2-year-survival patient group (t =3.50,P ＜0.01).ConclusionThe suPAR value was correlated to the stability of multiple myeloma,and can be used for disease prognosis and estimation of survival time.And the high expression of suPAR was related to the adverse prognosis.

Objective To observe the efficacy and toxicity of low dose thalidomide combined with VAD regimen contained one-week dexamethasone in treatment on patients with multiple myeloma (MM). Methods 42 patients with MM were diagnosed in our hospital.The VAD regimen contained one-week dexamethasone was vincristine 0.4 mg/d, adramycin 10 mg/d and dexamethasone 40 mg/d for 4 days. At the same time, thalidomide is given 150-200 mg/d. Results The overall response rate (ORR) is 80.95%. Before and after treatment, all the detection indicators in MM patients were statistically different (P＜0.001). There is small adverse reactions. Conclusion Low dose thalidomide combined with VAD regimen contained one-week dexamethasone in treatment of MM has more merits such as less side effects, good tolerance, convenient administration and significant curative effects, so it should be recommended in clinical works.

ObjectiveTo evaluate the application value of magnetic resonance diffusion weighted imaging (DWI)in diagnosis and differential diagnosis of prostate cancer. Methods53 Cases of suspected prostate cancer patients with elevated prostate-specific antigen, abnormaldigital rectal examination or ultrasound examination were underwent DWI examination before operation. Apparent dispersion coefficient was measured and compared to pathological results. Results There were 15 cases of prostate cancer, 37 cases of benign prostate hyperplasia and one prostatic intraepithelial neoplasia. When b =1 000 s/mm2 ,the ADC values of foci area in prostate cancer group and peripheral zone in benign prostate hyperplasia group were (0.813 ±0.25) × 10-3mm/8 and (1.45±0.24) × 10-3mm/s respectively, and the difference had statistical significance(t =-26. 117,P ＜0. 01 ). When b =60D s/mm2, the ADC values of foci area in prostate cancer group and peripheral zone in benign prostate hyperplasia group were ( 1.03 ± 0. 27) × 10-3 mm/s and ( 1.62 ± 0. 33) × 10- 3 mm/s respectively, and the difference had statistical significance( t =- 24. 191, P ＜ 0. 01 ). The area under the ROC curves was 0.862, and the sensitivity and specificity of DWI were 78.1％ and 91.5％ respectively.ConclusionDWI can provide quantitative information for prostate cancer diagnosis and differential diagnosis,therefore it possesses a good clinical application value.

OBJECTIVETo evaluate the effects of Attractin (Atrn) silence on the anti-oxidative and anti-apoptotic abilities of TM4 Sertoli cells and its influence on the expressions of superoxide dismutase (SOD) and caspase6 in the cells.

METHODSWe observed the apoptotic indexes of TM4 Sertoli cells with normal expression (control), partial deletion, and complete deletion of the Atrn gene (psiRNA-TM4, psiAtrn-TM4, and mu-SC). We determined the mRNA and protein expressions of SOD and caspase6 by Q-PCR and Western blot, measured the SOD activity and malondialdehyde (MDA) contentby spectrophotometry, and detected the apoptotic index of the cells by TUNEL.

RESULTSCompared with psiRNA-TM4, after inhibition of the Atrn expression, the Sertoli cells in the psiAtrn-TM4 and mu-SCgroups showed significantly decreased expressions ofSOD mRNA (70.76% and 92.58%) and protein (65.11% and 71.0%) (both P < 0.05). The levels of caspase 6 mRNA and protein were increased 5.28 and 3.40 times in the psiAtrn-TM4 and 2.97 and 2.50 times in the mu-SCgroup as compared with the normal control (both P < 0.05). Atrn deletion markedly increased the apoptotic indexes of the cells in the psiAtrn-TM4 and mu-SC groups by 16.22% and 22.03% (P < 0.05) and reduced the activity of SOD by 23.00% and 39.37% (P < 0.05); it also elevated the level of MDA by 155.22% (P < 0.05).

CONCLUSIONThe Atrn gene exerts influence on the function of Sertoli cells in multiple ways, in which antioxidative stress and apoptosis regulation may play an important role.

OBJECTIVEThis study aims to investigate the caries status of the first permanent molar and primary tooth among 7- to 9-year-old children in Tangshan city and the correlation between caries of primary tooth and the first permanent molar.

METHODSA stratified cluster sampling method was used on the basis of the Basic Approach of Oral Health Survey of WHO and the Guideline of the Third National Oral Health Survey. A total of 10 primary schools were randomly sampled in clusters that included 51 primary school sampling spots in Tangshan. The caries status of 1 794 children aged 7 years to 9 years was examined.

RESULTSThe prevalence rate of the first permanent molar caries was 47.49% (852/1 794), the mean number of DMFT was 1.30 ± 1.59, the mean number of DMFS was 1.96 ± 3.40, and the filling rate was only 2.35% (20/852). The preva- lence rate and mean DMFT of the first permanent molar caries showed significant difference between different ages and genders (P < 0.05). However, the mean DMFS of the first permanent molar caries only showed significant difference between the various ages (P < 0.05). The prevalence rate of the primary tooth caries was 83.11% (1 491/1 794), the mean number of dmft was 4.82 ± 3.55, the mean number of dmfs was 6.51 ± 5.61, and the filling rate was 12.41% (185/1 491). Caries of primary tooth was the first permanent molar caries risk factor [r = 0.277, OR = 5.736, P = 0.00, 95% CI (4.175, 7.881)]. Significant correlation was found between the caries of primary tooth and first permanent molar (r = 0.274, P < 0.001).

CONCLUSIONCaries status of the first permanent molar among 7- to 9-year-old children in Tangshan city is serious. Caries status of primary tooth may play an important role in predicting the first permanent molar caries in clinic and prevention.
