Objective:To investigate the effect of donor lymphocyte infusion (DLI) by intra-bone marrow (IBM) or intravenous (IV) on the incidence of graft-versus-host disease(GVHD) after allogeneic peripheral hematopoietic stem cell transplantation (allo-PBSCT).Methods:Female C57BL/6 mice as recipients received total body irradiation (TBI) on day 0,followed by injection of peripheral hematopoietic stem cells from mobilized male BALB/c with granulocyte-colony stimulating factor (rhG-CSF),and DLI was performed via IV or IBM.The extent of GVHD was compared in recipients received allogeneic IBM-DLI with those received IV-DLI.The percentage of donor-derived cells and CD4~+CD25~+ regulatory T cells (Tregs) was detected by flow cytometry.14 days after DLI,the levels of IL-4 and interferon (IFN)-γ were tested by ELISA.Results:It was found that the frequency and severity of GVHD were reduced in IBM-DLI compared with that of IV-DLI (P＜0.01).7 days after transplantation,the percentage of H-2~d-positive cells was over 95% in all surviving transplanted mice;and 14 days after transplantation,the percentage of Tregs detected as CD4~+CD25~+ was significantly higher in recipients treated with IBM-DLI than those treated with IV-DLI(P＜0.01).Compared with that of the recipients in IBM-DLI group,the level of IL-4 was significantly decreased,while the level of IFN-γ were elevated in group IV-DLI (P＜0.01).Conclusion:IBM-DLI could induce the proliferation of Tregs and the Th polarizing to Th2,resulting in decreasing the incidence and alleviating severity of GVHD after allo-PBSCT.

Objective To investigate the effect of valsartan,an angiotensinⅡtype 1 receptor (AT1 R)blocker,on radiosensitivity,invasive potential and proliferation activity of nasopharyngeal carcinoma cells(CNE-2)in vitro. Methods Radiosensitization of valsartan on CNE-2 cells in vitro was investigated by colony forming assay.Effect of ATl R blocker combined with radiation on invasive potential of CNE-2 cells was evaluated using 24-well Matrigel invasion chambers(Transwell).Apoptosis-inducing effect of valsartan combined with radiation on apoptosis of CNE-2 was identified by flowcytometry(FCM). Resuits When valsartan was given at 10-9.10-8 and 10-7 mol/L combined with radiation,sensitivity enhancement ratios (SER)were 1.10,1.20 and 1.36.and the invasive inhibition rates were 8.11%,16.49%and 16.77%,respectively.The SER of valsartan on CNE-2 distinctly increased when the exposure time was increased.After 24 h exposure to 10-8 mol/L valsartan combined witIl radiation.the apoptosis rate was 1.89%±0.09%,which was higher than 1.62%±0.06%in radiation alone group(t=4.79.P＜0.05). Conclusions AT1 R blocker valsartan combined with radiation can significantly inhibit the proliferation activity of nasophar,cngeal carcinoma cells in vitro in a dose- and time-dependent manner.Valsartan combined with radiation can potently inhibit the invasive potential of CNE-2.which may be involved in the mechanism of valsartan treatment in vivo.

·AIM: To report the results of phacotrabeculectomy with 2.8mm scleral tunnel incision.·METHODS: Phacotrabeculectomy was performed through an identical 2.8mm scleral tunnel incision in 52 eyes of 49 patients with cataract and glaucoma. The incision was closed with out suture. Foldable intraocular lens was implanted in all eyes.·RESULTS: The control of intraocular pressure on 36 eyes was desirable. The average postoperative intraocular pressure was (8.24±3.61)mmHg, (13.22±4.12) mmHg, (12.11±4.23)mmHg and (12.59±4.26)mmHg at one week, one month, three months and six months. As compared with 56 eyes in which phacotrabeculectomy was performed with 5.5mm scleral tunnel sutureless incision, there was no statistical difference, between the two, regarding the mean postoperative intraocular pressure at six months (t=1.7536,P=0.08239).The retinal nerve fiber layer thickness was not statistically different between the preoperative and postoperative times in one year in 26 eyes. The uncorrected postoperative visual activity was 0 8 or better in 62% of 52 eyes.·CONCLUSION: The advantages of this operative method are minimal size scleral flap, smaller and sutureless incision, immediate chamber restoration, decrease in postoperative astigmatism, enhanced postoperative visual activity, reduced postoperative inflammatory response and complications.

OBJECTIVETo investigate the diagnostic value of MRI in radial head fracture with forearm interosseous membrane injuries.

METHODSFrom December 2011 to December 2012,26 patients with fractures of capitulum radial in our hospital were collected. There were 15 males and 11 females, ranging in age from 21 to 53 years old,with an average of 37.6 years old. All the patients visited hospital within 72 hours after injuries. X-ray radiography of full ulnar radial length in injured side, CT in injured side (three-dimensional reconstruction if necessary) and MRI (including the elbow and wrist joints) were performed within a week after the injury. The MRI manifestations of the forearm interosseous membrane (with or without damage, the injured location and the injury degree ) and the fractures degree of radial head were observed and compared for the relativity.

RESULTSRadial head fracture from Mason type I to III was associated with the forearm interosseous membrane injury. Radial head fracture degree was positive correlated with forearm interosseous membrane injury degree (P < 0.05).

CONCLUSIONRadial head fracture with suspicious forearm interosseous membrane injury is necessary to take MRI for checking for any interosseous membrane injury and injury degree, then choose the right treatment for radial capitulum fracture, only in this way can be helpful for the functional recovery of elbow and forearm.

Objective To retrospectively study the risk factors of aortic arch calcificationand its influence on the survival prognosis of maintenance peritoneal dialysis patients. Methods One hundred seventy-seven cases of maintenance peritoneal dialysis patients were enrolled, including 66 cases of aortic arch calcification cases. Their general dialysis data were collected for the evaluation of dialysis adequacy and residual renal function, and their chest X-rays were recorded to assess the degree of aortic arch calcification. The two variables Logistics regression was used to analyze independent risk factors of aortic arch calcification; Kaplan-Meier analysis was used to analyze the influence on prognosis of dialysis patients; and multivariate COX regression was employed to analyze independent risk factors of death in dialysis patients. Results Among the 177 selected cases of peritoneal dialysis patients, 66 cases (37.29%) presented with aortic arch calcification. Elevated serum phosphorus was an independent risk factor of aortic arch calcification (OR=54.69 ,95%CI:10.01-298.65, P<0.01). The probability of survival in patients with mild and moderate (severe) calcification of aortic arch was less than those without calcification. Moderate (severe) calcification of aortic arch was the independent risk factor of all-cause mortality and cardiovascular disease mortality, whose hazard ratios in patients with calcification were 3.779 times and 5.636 times of those in patients without calcification respectively. Conclusions Hyperphosphatemia is an independent risk factor promoting the development of calcification of aortic arch. The probability of survival in patients with mild and moderate (severe) calcification of aortic arch is less than those without calcification; moderate (severe) calcification of aortic arch is the independent risk factor of all-cause mortality and cardiovascular disease mortality.

AIM: To explore the localization and expression of transfo rming grow th factor-? 1,2 (TGF-? 1,2 ) and alpha-smooth muscle actin (?- ASMA) in fetal a nd adult skins. METHODS: Skins of 15 cases of fetuses with different gestational ages and 5 cases of adults were taken, embedded with paraffin wax, and sectione d. Immunohistochemistry method and pathological method were used to detect the e xpression intensity and distribution of TGF-? 1,2 and ?-ASMA. RESULTS: Positive immunohistochemical signals of TGF-? 1,2 and ?-A SMA were found in fetal and adult skins. In skins derived from young fet us, the positive signals of these three proteins were very weak. Along with the incr ement in gestational age, the positive cellular rates of TGF-? 1,2 and ?- ASMA were elevated pro gressively. In elder fetal and adult skins, TGF-? 1,2 were mostly distributed i n epidermal cells, endothelial cells and some fibroblasts, while ?-ASMA was mainly located in myofibroblasts and sweat gland epithelial cells. CONCLUSION: The endo genous TGF-? 1,2 might be involved in the cutaneous development at embryoni c stage, in the cutaneous structure maintenance at adult stage, and in the wound healing af ter injury.

Objective To investigate the causes and factors of hemoglobinuria in patients with thrombosis after AngioJet mechanical thrombectomy.Methods The clinical data of 16 patients with thrombosis treated by AngioJet thrombectomy system were retrospectively analyzed.Nine patients with hemoglobinuria during the procedure were included in group A,while 7 patients without hemoglobinuria in group B.The type of surgical procedure,time of intraoperative aspiration and the thrombus volume were compared between both groups.Results Nine (9/16,56.23 ％) of 16 patients were found hemoglobinuria during and after AngioJet mechanical thrombectomy.There were no statistically significant differences in surgical approaches (x2 =1.667,P=0.197),the time of intraoperative aspiration ([320.11±108.80]s vs [265.29±31.46]s,t=0.741,P=0.457),the thrombus volume (x2=0.442,P=0.506) between both groups.No renal function failure were noted directly relating to the use of the AngioJet thrombectomy device.Condusion There are many factors influenced the occurrence of hemoglobinuria in the patients after AngioJet thrombectomy.It can be reduced by using reasonable type of intraoperative aspiration,controled time of aspiration and active perioperative symptomatic treatment.
