Objective:To evaluate the effect and safety of rifabutin combined with multi-drugs in the treatment of multi-drug resist-ant tuberculosis with long-term therapy. Methods:Totally 86 cases of patients with multi-drug resistant tuberculosis were divided into the control group and the treatment group with 43 ones in each according to a random number table method. The two groups were trea-ted with levofloxacin, pasiniazid, ethambutol, protionamide and amikacin etc. The control group was treated with rifapentine, and the treatment group was treated with rifabutin additionally. After 18-month treatment, the negative conversion ratio of sputum smear and sputum mycobacterium tuberculosis culture, lesion absorption rate and cavity closure rate of X-ray chest radiograph and adverse reac-tions in the two groups were compared. Results:The negative conversion ratio of sputum smear and sputum mycobacterium tuberculosis culture in the treatment group was 41. 86% and 32. 56%, respectively, which were similar with those in the control group ( P >0. 05). There were no significant differences in lesion absorption rate and cavity closure rate of X-ray chest radiograph and adverse re-actions between the two groups (P>0. 05). Conclusion:Rifapentine or rifabutin combined with multi-drugs in the treatment of multi-drug resistant tuberculosis can improve the negative conversion rate of sputum mycobacterium and lesion absorption and cavity closure with high safety.

OBJECTIVE To study the effect of valproic acid ( VPA) on radiosensitivity to MCF7 breast cancer cells. METHODS MCF7 cells were pretreated with VPA 0.5 and 1 mmol.L-1 for 0, 24, 48 and 72 h respectively, irradiated with 8 Gy lR, and at 6 h post-lR, the γ-H2 AX foci formation in MCF7 cells was tested by immunofluorescence assay. MCF7 cells were pretreated with VPA 0.5 and 1 mmol.L-1 for 72 h, irradiated with 4 Gy lR, and at 48 h post-lR, the cell survival rate was detected by MTT assay. MCF7 cells were pretreated with VPA 0.5 mmol.L-1 for 24 h, and then irradiated according to the amount of cells: 2 Gy (500 and 1000 cells per plate), 4 Gy (2000 and 4000 cells per plate), 6 Gy (8000 and 16000 cells per plate), and the cloning efficiency was calculated. MCF7 cells were pretreated with VPA 0.5 and 1 mmol.L-1 for 0, 24, 48 and 72 h respectively and the cell cycle profile was analyzed via flow cytometry. RESULTS After treatment with VPA alone for 24 h, MCF7 cells showed a significant increase in the amount of γ-H2 AX foci formation ( P < 0. 01). lt was also found that VPA increased lR-induced γ-H2 AX foci formation, which obviously prolonged the pretreatment time of VPA(P<0.01) in a time-dependent manner(r=0.98, P<0.05). VPA 0.5 and 1 mmol.L-1 had the same effect on γ-H2 AX foci formation. Furthermore, VPA was able to cause a significant decrease in lR-induced clonogenic survival but an increase in lR-induced cytotoxicity by MTT assay. Also, VPA alone decreased the plating efficiency of MCF7 cells. However, the cycle profile of MCF7 cells treated with both VPA 0.5 and 1 mmol.L-1 was not changed. CONCLUSION Without affecting the cell cycle profile, both the safe and critical dose of VPA used in clinical epilepsy treatment can significantly increase the accumulation of DNA double strand breaks in the cells and sensitize the cells to lR treatment, suggesting that VPA can induce radio-sensitization of breast cancer cells.

Objective To analyze the ability of rheumatologistto read the magnetic resonance imag of sacroiliac joint of spondyloarthritis patients.Methods The questionnaire survey were conducted among rheumatologists and the answers of the questionnaires were analyzed by quantitative analysis.Results 66.9％ (75/112) rheumatologist did not known how to choose the sequence of magnetic resonance imaging,and 55.4％(62/112) rheumatologist thought that bone marrow edema was very important for the diagnosis of spondyloarthritis,but only less than 10％ rheumatologists thought that erosion and fat infiltration could also h elp to make the diagnosis of spondy-loarthritis.Conclusion It is very important for rheumatologists to receive training on the reading of magnetic resonance images of sacroiliac joint of spondyloarthritis patients.

Objective To investigate spinemagnetic resonance imaging(MRI) findings in patients with axial spondyloarthritis (SpA) and to analyze the correlation between imaging and clinical manifestation.Methods The clinical data of patients with axial SpA were recorded.All patients underwent whole spine MRI scanning.The MRI findings of spinal involvement were explored.Moreover,the correlation between lesions in spinal MRI and Bath Ankylosing Spondylitis Disease Activity Index(BASDAI),Bath Ankylosing Spondylitis Functional Index (BASFI),Bath Ankylosing Spondylitis Metrology Index (BASMI),nocturnal pain visual analogue scale (VAS) score,back pain VAS score,global disease activity VAS score,Ankylosing Spondylitis Disease Activity score (ASDAS),erythrocyte sedimentation rate,C-reactive protein was analyzed.Results Thirty-three patients with axial SpA were included in this study.The image abnormalities of the spine were confirmed in 29 axial SpA patients by MRI,including Romanus lesion,Andersson lesion,the inflammation of facet joints and syndesmophyte.In correlation study,BASMI was positively correlated to the numbers of acute Romanus lesions,chronic Romanus lesions,chronic Andersson lesions and whole spinal lesions(r =0.440,P＜0.05; r =0.483,P＜0.05; r=0.421,P＜0.05; r=0.589,P ＜ 0.05 respectively).There was a statistically significant correlation between chronic Andersson lesions and BASFI(r =0.392,P ＜0.05).But no significant associations were found between MRI lesions and other clinical findings.Conclusions MRI lesions in axial SpA were associated with findings reflecting the spinal function,which can better guide the clinical treatment.

Objective To investigate the effects of dexmedetomidine on renal function in patients with hemorrhagic shock undergoing emergency surgery.Methods Sixty patients (27 males, 33 females) with hemorrhagic shock, aged 18-69 years, ASA physical status Ⅲ or Ⅳ, required emergency surgery under general anesthesia, were randomized into two groups (n=30 each): dexmedetomidine group (group D) and control group (group C).The patients in group D receiving a loading dose of dexmedetomidine (0.5 μg/kg within 10 min) after the induction of anesthesia followed by a continuous infusion rate of 0.4 μg·kg-1·h-1 till 30 min before the end of surgery, while those in group C received equal volume of normal saline.Venous blood were obtained immediately before beginning of surgery (T1), immediately after surgery (T2), 24 h after surgery (T3) and 72 h after surgery (T4) for detecting the concentrations of the serum creatinine (Scr) and blood urea nitrogen (BUN), the contents of neutrophil gelatinase-associated lipocalin (NGAL) and high mobility group box-1 (HMGB1).The range ability of the concentration of the serum Scr from T4 to T1 (ΔScr) and the content of the serum HMGB1 from T4 to T1 (ΔHMGB1) were also calculated and recorded.Hemodynamic index (including MAP, HR) and arterial blood gas results were recorded during surgery.Results Compared with T1, MAP, CVP and BE were increased, meanwhile, HR and Lac were decreased at T2, but there was no statistically significant difference between the two groups.No statistical difference was found in BUN at any time point between group D and group C.Compared with T1, Scr decreased in both groups at T2-T4.The ΔScr in group D was higher than that in group C at T4 (P＜0.05).The content of serum NGAL at T4 in group D was significantly dropped when compared with T1 (P＜0.01) and was lower than that in group C (P＜0.05).Compared with T1, the content of serum HMGB1 was significantly decreased in both groups at T2 (P＜0.05);the content of serum HMGB1 at T3 in group C was significantly increased and was higher than that in group D;the ΔHMGB1 in group C was higher than that in group D.Conclusion Hemorrhagic shock could induce acute kidney injury.Perioperative continuous infusion of dexmedetomidine facilitated renal function recovery after ischemia-reperfusion injury in patients with hemorrhagic shock through inhibiting the elevation of serum HMGB1.

Objective To retrospectively analyze the effect and safety of bilateral stereotactic radiofrequency amygdalohippocampectomy (SAHE) for treatment of bilateral medial temporal lobe epilepsy (BMTLE). Methods Twelve BMTLE patients were treated with bilateral SAHE under limited coagulations. Clinical parameters were evaluated with the programs of Engel′s classification, Liverpool Seizure Severity Scale (LSSS) 2.0, Wechsler Adult Intelligence Scale-Revised (WAIS-R) and Wechsler Memory Scale-Revised (WMS-R), respectively. Results Five patients (42%) were assessed as EngelⅠwith 12 ~ 62-month follow-up. Seizure severity scores were declined sharply compared with the baseline of the patients with out seizure free. Function of memory and intelligence was transiently declined without statistical significance immediately after operation (P >0.05), but was significantly increasedat 6 months after operation (P < 0.05). Conclusion Bilateral SAHE could terminate seizures or reduce seizure severity in patients with BMTLE. Under the circumstance of limited coagulations, neuropsychological function was improved along with seizure control.
