Objective To morphologically evaluate the bone marrow (BM) smear specimens collected from the patients with chronic myelogenous leukaemia (CML) in accelerated phase and blastic phase receiving a short term Gleevec therapy, and to determine its clinical significance in evaluating the changes in disease condition to guide the treatment. Methods Sequential BM smear specimens of 16 Ph positive CML patients, including 9 in accelerated-phase and 7 in blastic-phase, were examined before and 3,6 and 9 weeks after Gleevec treatment (0.4/d or 0.6g/d, PO) with routine method. Periodic acid-Schiff reagent (PAS) staining was performed for a proper identification of abnormal erythroid precursor cells. Results The treatment rapidly caused following conspicuous BM changes in the process: both cellular proliferation and neutrophil granulopoiesis decreased significantly, while the accumulation of erythroid precursor cells increased obviously, and megakaryocytes decreased markedly at 3rd week. A few patients showed no such changes, but an accumulations of erythroid precursor cells, leading to misdiagnosis in some one third of the patients. In 21 percent of patients, in whom no erythroid cells were found, were classified into accelerated phase and blast phase based on both WHO classification system and FAB system. In fact the increase in red system was a bone marrow response to anemia caused by Gleevec therapy. If a condition of severe cellular proliferation of BM with a lower WBC and platelets appeared, most patients could not tolerate the therapy, then it should be ceased. Conclusion Initial treatment with Gleevec therapy exerts pronounced changes in BM morphology, which can be used as a simple and effective method to evaluate the outcome of the patients.

Objective To investigate the effects of supported employment(SE) on the vocational rehabilitation for schizophrenic rehabilitants.Methods 108 schizophrenic rehabilitants with stable conditions were recruited and randomly allocated into the control group and experimental group.Fifty-four cases in the control group received the general outpatient service and follow-up service with drug maintenance therapy and 54 cases in the experimental group received SE with drug maintenance therapy.At the baseline and the end of the sixth month,all of the 108 cases were assessed by the Positive and Negative Syndrome Scale (PANSS) and Work-related Social Skills Scale (WSSS) respectively.The competitive employment rate and average working days of the two groups were evaluated at the end of the sixth month.Results There was no significant difference in the total score of WSSS,and the total score of PANSS and its sub-scores on the Positive Scale,Negative Scale and General Psychopathological Scale betweeu the two groups at the baseline(P＞ 0.05).At the cnd of the sixth months,significant differences (P＜0.01 ～ 0.05) were found in the total score of WSSS,the sub-score of the Negative Scale,the competitive employment rate and the average working days((35.11 ± 12.71) d vs(20.15 ± 8.04) d) between the experimental and control groups.Conclusion SE can increase the employment rate of schizophrenic rehabilitants,improve their abilities to acquire and maintain competitive employment,and meanwhile relieve their negative symptoms.

OBJECTIVETo analyze the clinical characteristics of elderly patients with spinal tuberculosis and explore its clinical effects with anti-TB drugs alone.

METHODSFrom January 2008 to July 2010, the data of 36 patients with spinal tuberculosis underwent conservative treatment of anti-TB drugs alone were analyzed. There were 19 males and 17 females with an average age of 73.5 years (ranged, 60 to 85). All patients were in the active phase with high ESR and CRP levels and were treated with 3HRZE/6-9HRE (course from 9 to 12 months). According to clinical symptoms, chemical examination, radiological image to adjust drug and depending on VAS score to evaluate pain.

RESULTSAll the patients were followed up from 8 to 24 months with an average of 15 months. Tuberculose of 31 patients healed after chemotherapy from 9 to 12 months and ESR and CRP recovered normally. Levofloxacin and para-amino salicylic acid were used in 4 cases because of 4 cases occurred drug fast for RFP or INH, after 15 months, their obtained healing. Symptom of 1 case got worse during chemotherapy, and surgical treatment were performed, after 3 months, ESR and CRP recovered normally, X-ray and CT showed spinal osteosclerosis and fusion without significant kyphosis and internal fixation loosening. Cobb angle was respectively(17.6+/-2.3) degrees, (18.1+/-2.7) degrees before treatment and last follow-up (P>0.05). MRI showed abscess was absorbed and spinal inflammation subsidised. VAS score was respectively 6.5+/-1.7, 1.4+/-0.5 before treatment and last follow-up (P<0.05). Seven patients had complications relating with drug adverse reaction,after discontinuation and treated with clinical symptom,the patients recovered normally.

CONCLUSIONAnti-TB drugs alone can obtain satisfactory effects in treating early senile spinal tuberculosis, but strict supervision and individual administration should not be disregardful.

Objective To determine the effects of urapidil on L-type calcium current(I_(Ca-L))in rat cardiomyocytes.Methods Ventricular myocytes were isolated from SD rats of either sex(250-280g)by retrograde perfusion of the hearts via aorta with calcium-free Tyrode solution containing enzyme as described elsewhere.Rod shaped cells with clear borders and striations were selected.Eighteen cells were randomly divided into 3 groups(n =6 each):A urapidil group;B urapidil+methysergide group and C methysergide group.All the cells in the three groups were peffused first with Tyrode solution for 1 min(T_1).In group A and C cells were then peffused with Tyrode solution containing 0.4 ?mol?L~(-1) urapidil(A)or 40 nmol?L~(-1) methysergide(C)for 1 min(T_2) while in group B cells were perfused fwst with Tyrode solution containing 0.4 ?mol?L~(-1) urapidil for 1 min (T_2) then with Tyrode solution containing methysergide 40 nmol?L~(-1) for 1 min (T_3).Finally the cells were again perfused with regular Tyrode solution for 1 min(T_4)to wash out the drugs.The peak of I_(Ca-L) was recorded at T_(1-4) by means of the whole cell patch clamp technique with use of Axo patch 200B.Results In group A,B and C the peak of I_(ca-L) at T_2 was significantly lower than that at T_1 but there was no significant difference between the peak of I_(ca-L) at T_1 and T_4.In group B the peak of I_(Ca-L) at T_3 was significantly lower than that at T_2.Conclusion Urapidil inhibits L-type calcium current in rat isolated cardiomyoeytes.It's inhibitory effect may not be mediated by 5-H_(1A) receptor.

Studies of biological feedback (BF) for the treatment of chronic prostatitis (CP) are occasionally reported have exhibited some related problems. This article presents an evaluation of the published literature on the BF treatment of CP at home and abroad in the aspects of instrument, method, application, effect, function, and mechanism. UROSTYMTM and MyoTrac are often employed and their operating paths are basically the same. NIH prostate symptom scores, urinary function, pain, sexual function, immune function, prostate fluid, and other indicators are generally used for the analysis of the effects of BF alone or in combination with other therapies on CP and its related symptoms. Either BF alone or BF combined with other therapies can promote urination, reduce pain, improve the quality of life, attenuate inflammation, improve sexual function, adjust immunity, and lessen physical and chemical stimulation. However, the relevant literature is of low quantity and quality, the reported studies are not standardized, and exploration of the action mechanisms is neglected.

Background Studies determined that rapamycin has not only the antibiosis but also suppressing the auto-immunology.The treating effect of rapamycin on experimental autoimmune uveoretinitis (EAU) is still concerned.Objective This work was to investigate the therapeutic effect of rapamycin on EAU and study the effect on the expression of inflammatory cytokines which were secreted by T lymphocyte subgroup in EAU.Methods EAU was induced in 20 SPF male Lewis rats by subcutaneous injection of interphotoreceptor retinoid binding protein (IRBP) R16 peptide emulsified in adjuvant.The rats were randomized into model control group and rapamycin injection group and 10 rats for each group.The rapamycin of 0.2 mg/( kg · d) 0.4 ml was intraperitoneally injected for the consecutive 7 days immediately after modeling,and the equal volume of normal saline solution was used at the same fashion in the model control group and 5 normal matched rats( normal control group).The ocular manifestation of the rats were examined under the slit lamp regularly.The retinal sections of the rats were prepared in the 14 days after modeling for the histopathological examination with hematoxylin and eosin staining.The ocular signs of inflammation and histopathological severity were scored based on the criteria of Caspi.Expression of interferon-γ (IFN-γ) and interleukin-17 (IL-17) in rat retinas were detected by immunohistochemistry.This experiment followed the Regulation for the Administration of Affair Concerning Experimental Animals by Tianjin Municipal Government.Results The scores of ocular signs elevated gradually from 6 through 12 days after modeling and slowly declined after that in the model control group.A same tendency was seen in the rapamycin injection group.The significant differences were seen in the scores of ocular signs between the two groups from 6 to 14 days( P＜0.01 ).The disorder of retinal structure and infiltration of inflammatory cells were seen in the model control group,but the retina layers were normal in the rapamycin injection group.The pathological score was evidently declined in the rapamycin injection group ( 0.90 ± 0.45 ) in comparison with model control group( 3.30±0.48 ) ( t =16.541,P＜0.01 ).The expressions of the IFN-γ and IL-17 in retina located in the outer nuclear layer,inner nuclear layer,internal plexiform layer and retinal ganglion cell layer with the weakened levels(A values) in rapamycin injection group compared with model control group,showing a considerably difference between them ( IFN-γ:21.16±4.23 vs 62.14 ±7.32; IL-17:49.86±6.59 vs 124.85 ±6.33 )(q=33.334,q=56.923,P＜0.01 ).Conclusions Rapamycin down-regulates the expressions of IFN-γ and IL-17 in retina and further eliminates the inflammatory response in the rat with EAU by the suppression of Th1 and Th17 cells function in EAU.

BackgroundStudies determined that Th17 cells are important inflammatory cell group in experimental autoimmune uveoretinitis ( EAU ).Interleukin-17 ( IL-17 ),as a marker of Th17,is involved in the occurrence and development of EAU.Mesenchymal stem cells (MSCs) play an immunomodulatory role,mainly by inhibiting the expression of Th17 in a variety of self-autoimmune disease.This is one of the current research focuses.ObjectiveThe present study was to investigate the therapeutic effect of MSCs in EAU and their impact on IL-17 expression in the retina.MethodsMSCs were isolated from the bone marrow of the femurs from 10 SPF Wistar rats and cultured and passaged.The third to fifth generations of cells were used in this experiment.EAU models were induced in 48 6-8 week-old SPF Lewis rats by subcutaneous injection of interphotoreceptor retinoid binding protein (IRBP) R16 peptide emulsified in adjuvant.EAU rats were randomly assigned to the model control group and the MSCs group.MSCs suspension (5×106) of 1 ml was injected via the rat tail vein once a day for 3 consecutive days after immunization,and the same amount of PBS was injected in the model control group in the same manner.Six matched normal Lewis rats were used as the normal control group.The inflammatory response was clinically examined under the slit lamp biomicroscope daily,and the histopathological changes of the retina were examined by hematoxylin and eosin staining on days 9,12,15 and 20.The clinical and histopathological scoring was performed according to the Caspi criteria.Expression of the IL-17 protein in the retina was detected by immunohistochemistry on 9,12,15 and 20days following molding.The use of the animals complied with the Regulations for the Administration of Affairs Concerning Experimental Animals by Tianjin Municipality Science and Technology Commission.Results MSCs showed the fusiform in shape and vortex-like growth.Flow cytometry verified that presented the positive expression for CD29 and CD44 but absent expression for CD45 and CD34.The scores of the anterior segment were significantly lower ( U=2.815,P =0.005 ; U =2.768,P =0.006 ; U =2.900,P =0.004 ; U =2.855,P =0.004 ),and the retinal inflammation scores were lower in the MSCs group than the model control group at various time points ( U =2.345,P =0.019 ; U =2.559,P =0.011 ; U =2.166,P =0.030 ; U =2.373,P =0.018 ).Im mnunochemistry showed that the expressions levels of the IL-17 protein (A value) in the rat retina were 26.47±5.68,77.78± 9.65,47.02±6.68 and 26.59±5.94 in the MSCs group on days 9,12,15 and 20,and those in the control group were 45.34±4.63,105.95± 10.74,64.11 ±9.76 and 37.02±6.51,showing a significant reduction ( t =6.305,P =0.000 ; t =4.799,P =0.001 ; t=3.540,P=0.005;t=2.900,P=0.016). ConclusionsMSCs can inhibit the aggravation of EAU and suppress the expression of IL-17 in ocular tissue.

Objective To evaluate the feasibility and initial experience of laparoscopic pyelolithoto- my within renal sinus.Methods A total of 19 patients(14 men and 5 women)of nephrolithiasis on 21 sides underwent laparoscopic pyelolithotomy within renal sinus.Of them,9 cases with other upper urinary tract diseases were treated by laparoseopic pyelolithotomy at the same time.The patient age ranged from 16 to 67 years(mean,41 years).The calculi were 1.2 to 3.5 cm in diameter,and were found on the right side in 11 cases,left side in 6,and both sides in 2.Five cases concomitantly had ureteral calculi;of them,1 had bi- lateral ureter calculi with ipsilateral steinstrasse,2 had pyelic polyp(1 with giant hydronephrosis after open ureterolithotomy),and 1 had giant bydronephrosis with pyelolithiasis during pregnancy with double-J tube drainage.Twelve cases(13 sides)had experienced unsuccessful extracorporeal shock wave lithotripsy,and 1 failed with minimally invasive percutaneous nephrolithotomy.Results The procedure was successful in all the 19 cases.The operative time ranged from 75 to 240 rain(mean,115 rain).The intraoperative blood loss ranged from 30 to 100ml(mean,50 ml).One case experienced 5-d urine leakage,and was spontaneously cured.The hospital stay was 5-9 d(mean,6 d).Double-J tube drainage was 4-6 weeks.During the follow- up(3-36 months),KUB and IVU showed no upper urinary tract stricture and no residual stones except for 1 stone of 0.7 cm in the renal lower calyx in 1 case.The kidney function was improved in all cases.Con- clusions Laparoscopic pyelolithotomy is new and minimally invasive alternative approach for renal calculi. With this procedure the urinary tract complications can be treated concomitantly,thus it can partially replace open surgery.

Objective To investigate the effect of SIRT6/NF-κB signal axis on delaying radiation-induced senescence of hematopoietic stem cell and progenitor cell with ginsenoside Rg1. Methods C57BL/6 mice were randomly divided into control group, model group and ginsenoside Rg1 group. The mice in model and ginsenoside Rg1 groups were exposed to total body irradiation with 6.5 Gy 60Coγ, the mice in ginsenoside Rg1 group were intraperitoneal injected with ginsenoside Rg1 (20 mg/kg) for 7 d before and after radiation. On day after taking medicine, the indicators in peripheral blood were observed to definite the information of hematopoietic reconstruction and the effect of ginsenoside Rg1 on it. Sca-1+ HSCs/HPCs were isolated and purified by magnetic activated cell sorting (MACS). The effect of ginsenoside Rg1 on delaying radiation-induced senescence of hematopoietic stem cell and progenitor cell was evaluated by mixed hematopoietic progenitor cell culture, cell cycle assay and senescence-associated β-galactosidase (SA-β-gal) staining. The expression of senescence associated SIRT6 and NF-κB mRNA and protein was examined by realtime fluorescence quantitative PCR (qRT-PCR) and Western blotting. Results After radiation, the indicator in peripheral blood of model group was decreased compared with control group. Sca-1+ HSC/HPC appeared aging character: The number of cells entered G0/G1 phase, the percentage of SA-β-gal positive cells was increased, the expressing of SIRT6 mRNA and protein were down regulated and NF-κB mRNA and protein were up regulated, and the number of CFU-Mix was decreased. Compared with the model group, the number of white blood cells (RBC), red blood cells (RBC), and platelet (PLT) in mice were increased, the number of cells entered G0/G1 phase and the percentage of SA-β-gal positive cells were decreased, and the number of CFU-Mix was increased in Sca-1+ HSC/HPC from the ginsenoside Rg1 group. Moreover, the expression of SIRT6 mRNA and protein were up regulated, and NF-κB mRNA and protein were down regulated in the ginsenoside Rg1 group. Conclusion SIRT6/NF-κB signal axis may play a key role in the antiaging effect of ginsenoside Rg1 to Sca-1+ HSC/HPC senescence induced by radiation.
