AlM:To find better ways of treating ocular alkali burn, and to reduce the suffering of patients and social burden.METHODS:Totally 100 patients were graded according to the degree of chemical burns to four major groups, each half were randomly divided into the control group and the treatment group. Control group underwent conventional treatment. ln addition to conventional therapy, patients in each treatment group were also added a Breviscapine intravenous injection of 40mg daily. Corneal recovery time, changes in vision, degree of corneal opacity, number of corneal neovascularization and other complications were observed. Curative effects were analyzed statistically.
RESULTS:There was no significant difference in levelⅠgroup between control group and treatment group ( P>0. 05); There were significantly different in level Ⅱ, Ⅲand Ⅳ group ( P<0. 05 ). Compared to the degree of corneal opacity and the number of corneal neovascularization, the treatment group was obviously better than the control group(P<0. 05).
CONCLUSlON: Breviscapine in the treatment of ocular alkali burns can shorten the course of treatment, reduce corneal scarring, and improve vision.

Objective To investigate the effect of silment information regulator factor related enzymes 1 (SIRT1) on the apoptosis of retinal ganglion cells (RGCs) in rats with diabetic retinopathy and its downstream molecular mechanisms.Methods Together 60 healthy male Sprague-Dawley rats were collected and randomly divided into normal group,diabetic group,SIRTI activator-resveratrol treatment group (treatment group),and diabetic rat model was induced by intraperitoneal injection of streptozotocin at 60 mg · kg-1 in the latter two group rats,while the normal group was injected with sodium citrate buffer at 60 mg · kg-1.Then,after 72 h,rats with blood glucose ＞ 16.7 mmol · L-1 were designated as diabetic rats by blood glucose test.Then each rat in the treatment group was treated with SIRT1 activator-resveratrol at 20 g · kg-1 once a day at the 2nd day after the success of the model,and the normal group and diabetic group were given methylene chloride.Finally,after immunohistochemical staining for retina,TUNEL assay was used to evaluate the apoptosis of RGCs,while the expression of SIRTI,p38 MAPK and Caspase-3 protein was detected by Western blot.Results The apoptotic index of RGCs in the normal group,diabetic group and treatment group was (0.848+0.131)％,(19.038 + 1.327)％,(10.461 + 1.089)％ respectively at 8 weeks,and the difference among the three groups was statistically significant (F =670.497,P =0.000),while the differences between each two groups were also statistically significant (all P =0.000).Furthermore,when compared with the normal group (0.132 ± 0.043),the expression of SIRT1 protein in the diabetic group (0.060 ± 0.028) and the treatment group (0.073 ± 0.026) was significantly decreased,and the overall difference among the three groups was statistically significant (F =1 310.663,P =0.000),while the differences between each two groups were also statistically significant (all P =0.000).The expression levels of p38 MAPK and Caspase-3 were increased in diabetic group (1.121 ± 0.082,0.266 ± 0.005) and treatment group (0.574 ± 0.012,0.190 ±0.060) respectively,and the overall difference and pairwise comparison in the three groups approached statistically significance (all P =0.000,0.000).Conelusion Up-regulation of SIRT1,can inhibit the apoptosis of RGCs,and protect RGCs against apoptosis in rat model of diabetic retinopathy,which may be correlated with the downregulation of p38 MAPK signal pathway.

Although 5-aminolevulinic acid (5-ALA)-mediated photodynamic therapy (PDT) has been demonstrated to be a novel and effective therapeutic modality for some human malignancies, its effect and mechanism on glioma are still controversial. Previous studies have reported that 5-ALA-PDT induced necrosis of C6 rat glioma cells in vitro. The aim of this study was to further investigate the effect and mechanism of 5-ALA-PDT on C6 gliomas implanted in rats in vivo. Twenty-four rats bearing similar size of subcutaneously implanted C6 rat glioma were randomly divided into 3 groups: receiving 5-ALA-PDT (group A), laser irradiation (group B), and mock procedures but without any treatment (group C), respectively. The growth, histology, microvessel density (MVD), and apoptosis of the grafts in each group were determined after the treatments. As compared with groups B and C, the volume of tumor grafts was significantly reduced (P<0.05), MVD was significantly decreased (P<0.001), and the cellular necrosis was obviously increased in group A. There was no significant difference in apoptosis among the three groups. The in vivo studies confirmed that 5-ALA-PDT may be an effective treatment for gliomas by inhibiting the tumor growth. The mechanism underlying may involve increasing the cellular necrosis but not inducing the cellular apoptosis, which may result from the destruction of the tumor microvessels.

BACKGROUNDMany patients requiring allogeneic hematopoietic stem cell transplantation (HSCT) do not have an human leukocyte antigen (HLA)-matched donor. Alternative donors, such as HLA mismatched family donors, are associated with higher rates of graft rejection and acute graft versus host disease (aGVHD) if T cells are not first depleted. We developed a new technique for HLA mismatched allogeneic HSCT using G-CSF primed bone marrow plus G-CSF-mobilized peripheral blood stem cells without ex vivo T cell depletion.

METHODSIn this study, 58 patients, including 33 with high-risk or advanced leukemia, were transplanted with cells from an HLA-haploidentical family donor with 1 - 3 mismatched loci. After conditioning, patients received G-CSF-primed bone marrow grafts that had not been depleted ex vivo of T cells, in combination with G-CSF-mobilized peripheral blood stem cells, as well as GVHD prophylaxis.

RESULTAll patients achieved sustained, full donor-type engraftment. The incidence of grade II-IV aGVHD was 37.9%, including 3 patients with grade III-IV aGVHD. The development of aGVHD was not associated with the extent of HLA disparity. Chronic GVHD was observed in 30 of 51 evaluable patients (65.4%). Fourteen patients died among whom 7 died of recurrent disease and 7 of transplant-related complications. Forty-four of the 58 patients survived, and 42 remained disease free at the time of a median follow-up of 12 months (3.5 to 39.5 months). The 2-year probabilities of disease-free survival were 74.8% and 69.3% for standard- and high-risk patients, respectively.

CONCLUSIONWe developed a new method to use bone marrow from haploidentical family donors without ex vivo T cell depletion, in combination with G-PBSCs, as a source of stem cells even in cases of HLA mismatched transplantation.

OBJECTIVETo investigate the prevalence of chronic kidney disease (CKD) in subjects with different glucose metabolism status.

METHODSBetween January, 2015 and October, 2015, a total of 934 subjects without a previous diagnosis of diabetes visiting the Department of Endocrinology or Health Examination Center underwent oral glucose tolerance test (OGTT), which identified 266 subjects with normal glucose tolerance (NGT group), 243 pre-diabetic subjects, and 425 patients with diabetes mellitus group. The baseline characteristics and laboratory test data of the subjects were collected. The diagnosis of CKD was established for an eGFR <60 mL/min/1.73 m(2) or a ACR≥30 mg/g, and the prevalence of CKD were compared among the 3 groups. Logistic regression model was used to analyze the OR value of the risk factors of CKD.

RESULTSThe prevalences of CKD in NGT, pre-diabetic and diabetic groups were 10.2%, 26.3% and 32.5%, respectively. Pairwise comparisons showed that the prevalence of CKD was significantly higher in pre-diabetic group (P<0.001, OR=3.17, 95% CI 1.94-5.17) and diabetic group (P<0.001, OR=4.27, 95% CI 2.72-6.65) than in NGT group, and was comparable between the pre-diabetic and diabetic groups (P=0.115, OR=1.35, 95% CI 0.95-1.91). Logistic regression analysis, after adjustment for age, gender, blood pressure, hypertension, blood lipids and uric acid, showed that pre-diabetes (OR=2.03, P=0.044) and diabetes mellitus (OR=2.22, P=0.016) were independently associated with CKD.

CONCLUSIONGlucose metabolism status has a significant independent impact on the incidence of CKD, suggesting the importance of early detection of pre-diabetes and timely interventions in pre-diabetic subjects in prevention CKD.

OBJECTIVEA randomized trial of breast self-examination (BSE) Program was carried out to evaluate whether the intensive BSE could reduce the number of deaths among women from breast cancer.

METHODSThis study was a randomized controlled trial (RCT). A total of 266 064 women (age of 30 to 64 years) associated with 519 textile factories in Shanghai had been randomly assigned to a BSE group (132 979 women) or a control group (133 085 women) since 1989. Initial instruction in BSE group would include demonstration of proper palpation techniques and was followed by 2 reinforcement sessions during the subsequent 4 years including video shows, BSE instruction sessions and BSE practice under medical supervision. These activities were continued for 5 years. Attendance at all events was recorded. The cohort was followed through July 2000 for development of breast diseases, and the breast cancer cases were followed through 2001 for vital status. Data analysis methods used would include Kaplan-Meier plots, log-rank test and Cox modeling.

RESULTSAmong women under instruction, 864 breast cancers detected and 133 breast cancer deaths occurred while 896 breast cancers were detected and 130 deaths recorded in the control group. The tumor size (P = 0.07), TNM stage (P = 0.39) and cumulative breast cancer mortality rate (P = 0.72) were not significantly different between the 2 groups. However, more and smaller fibroadenomas were detected in the instruction group than in the control group (P< 0.01).

CONCLUSIONIntensive instruction in BSE did not seem to have reduced the mortality rate of breast cancer, but more and smaller benign breast lumps could be detected.

OBJECTIVESTo study clinical characteristics and outcome of pure red cell aplasia (PRCA) following major ABO-incompatible allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODSVariables including sex, age, stem cell source, granulocyte engraftment time, blood transfusion and isoagglutinin type against donor RBC were analyzed to identify risk factors for the development of PRCA.

RESULTSTwelve of 100 patients received major ABO-incompatible allo-HSCT developed PRCA, with out any effect on incidence of aGVHD and CMV infection. ABO blood groups of recipient/donor pairs of these twelve PRCA patients were O/A in nine, B/A in one and O/B in two. Patients with anti-A isoagglutinins against donor RBC developed PRCA more frequently than those with anti-B (10/49 vs 2/49). Median duration to the recovery of erythropoiesis tended to be longer in patients with PRCA (PRCA vs non-PRCA, 203.5 vs. 76 days, P < 0.05 ). Median durations to the disappearance of incompatible isoagglutinins tended to be longer in patients with PRCA (PRCA vs. non-PRCA, 150.5 vs. 60 days,P <0.05) and in those with anti-A isoagglutinins (anti-A vs anti-B, 90 vs 55 days, P < 0.05).

CONCLUSIONABO blood group of O/A in recipient/donor pair was the only high risk factor for PRCA after major ABO-incompatible allo-HSCT.

OBJECTIVETo evaluate the use of a new reduced intensity of BuCy conditioning regimen for the treatment of malignant hematologic diseases in aged or intolerable patients receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT) from the siblings.

METHODSTwelve patients with acute lymphoblastic leukemia (ALL, n = 4), acute myelogenous leukemia (AML-M(2), n = 2), chronic myelogenous leukemia (CML, n = 4), and myelodysplastic syndromes-refractory anemia with excess blasts (MDS-RAEB, n = 2) were intolerant of conventional myeloablative therapy because of age (older than 50 years) or having severe concurrent diseases. The median age was 49 years (range 42-64 years). Seven were males and five females. Two of the 12 patients were HLA one antigen-mismatched and the rest HLA identical with their donors. The low dosage conditioning regimen consisted of busulfan (2 mg.kg(-1).d(-1) for 3 days), Ara-C (2 g.m(-2).d(-1) for 1 or 2 times), cyclophosphamide (1.0 g.m(-2).d(-1) for 2 days) and anti-T-lymphocyte globulin (ATG 2.5 mg.kg(-1).d(-1) for 4 days, -5 - -2 day). Granulocyte colony-stimulating factor mobilized bone marrow and peripheral blood stem cells (PBSC) were harvested (1 patient using PBSC alone). All patients received cyclosporin A, short-term MTX and mycophenolate mofetil (MMF) for prophylaxis of acute graft-versus-host disease (aGVHD). DNA short tandem repeat (STR) sequence analysis, cytogenetics and molecular-biologic technique were used to analyze chimerism.

RESULTSAll the patients were well tolerated the regimen, with no severe regimen related toxicity. In all the 12 patients, absolute neutrophil count > or = 0.5 x10(9)/L was achieved in 11 to 17 (median 15) days and platelet count > 20 x 10(9)/L in 10 to 23 (median 15) days after transplantation. Complete chimerism was achieved in 11 patients and 1 patient was in mixed chimerism at one month after HSCT. With a median follow-up of 14.5 (4.0-24.0) months, 7 of the 12 patients (58.0%) were alive and 5 (42.0%) of the 7 were disease-free. The probabilities of OS and DFS at 12 months were 75.0% and 48.1%. Five patients (41.6%) had aGVHD and four had local chronic GVHD with a cumulative probability of chronic GVHD of 41.5%.

CONCLUSIONThis reduced intensity conditioning regimen is well tolerated and safe for HSCT in the older patients or patients with severe concurrent medical conditions and can achieve full chimerism and long-term disease-free survival.

OBJECTIVETo compare the long-term results of laparoscopic and open radical resection for colorectal carcinoma.

METHODSTwo hundred and fifteen patients with colorectal cancer from January 1996 to September 2000 were non-randomly divided into laparoscopic and open operation groups. Local recurrence, distant metastasis, 5-year survival rate and long-term postoperative complications were compared between the two groups.

RESULTSEighty-seven cases received laparoscopic resection and 128 cases received open operation. There were no statistical differences in age, sex and tumor stage between the two groups (P > 0.05). The 5-year-survival rate was 70% in open operation group, and 78% in laparoscopic group (P > 0.05). There were no significant differences in the incidences of local recurrence, distant metastasis, incision seeding, and incision hernia between the two groups (P > 0.05). The complication rate of postoperative adhesive intestinal obstruction was significantly lower in laparoscopic group than that in open operation group (P< 0.05).

CONCLUSIONSLong-term results of laparoscopic resection are similar to those of open resection for colorectal carcinoma, but laparoscopic surgery has less long-term complications.
