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.

OBJECTIVE: To explore the effect of traditional Chinese herbal medicine (TCM) for nourishing liver and kidney, clearing meridians and removing toxic substances, on the neurobehavioral manifestations and the activity of the dopamine D2 receptor in rat with levodopa-induced dyskinesias (LID). METHODS: The rat model of Parkinson's disease (PD) was established by injecting 6-hydroxydopamine (6-OHDA) into right substantia nigra of brain, then, the model of LID in rat was produced by injecting levodopa (LD) and benserazide for 4 weeks. The rats were divided into normal control group, 4-week LD treated group, 4-week LD plus TCM treated group, 8-week LD treated group, and 8-week LD plus TCM treated group, and the effect of the TCM on neurobehavioral manifestations was observed. The radioligand binding assay (RLBA) and Scatchard drawing were used to measure the maximal binding capacity of receptor (Bmax) and equilibrium dissociation constant (KD) of the dopamine D2 receptor in corpora striatum. RESULTS: Compared with the 4-week LD treated group and 8-week LD treated group, TCM could decrease abnormal involuntary movement scores of the rats with LID; the RLBA revealed that the dopamine D2 receptor Bmax significantly increased (P<0.05, P<0.01) and the KD significantly decreased (P<0.05). CONCLUSION: TCM can improve the activity of the dopamine D2 receptor and relieve the symptoms of LID.

One case with fulminant type 1 diabetes during the third trimester of pregnancy was reported.If a patient manifests abrupt onset of hyperglycemia,nausea,vomiting,and bellyache during pregnancy or immediately after delivery,fulminant type 1 diabetes should be considered.
