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.

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.

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.

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.

BACKGROUNDPancreatic cancer is one of the most lethal human cancers with a very low survival rate of 5 years. Conventional cancer treatments including surgery, radiation, chemotherapy or combinations of these show little effect on this disease. Several proteins have been proved critical to the development and the progression of pancreatic cancer. The aim of this study was to investigate the effect of resveratrol on apoptosis in pancreatic cancer cells.

METHODSSeveral pancreatic cancer cell lines were screened by resveratrol, and its toxicity was tested by normal pancreatic cells. Western blotting was then performed to analyze the molecular mechanism of resveratrol induced apoptosis of pancreatic cancer cell lines.

RESULTSIn the screened pancreatic cancer cell lines, capan-2 and colo357 showed high sensitivity to resveratrol induced apoptosis. Resveratrol exhibited insignificant toxicity to normal pancreatic cells. In resveratrol sensitive cells, capan-2 and colo357, the activation of caspase-3 was detected and showed significant caspase-3 activation upon resveratrol treatment; p53 and p21 were also detected up-regulated upon resveratrol treatment.

CONCLUSIONResveratrol provides a promising anti-tumor strategy to fight against pancreatic cancer.

This study was aimed to investigate various factors influening erythrocyte recovery following ABO-incompatible allogeneic HSCT. 157 patients following ABO-incompatible allogeneic HSCT were selected for the investigation. Cox regression analysis were used to identify the statistically significant factors including sex, age, schemes of transplantation, HLA-matched, mismathed, conditioning regimens, preventive measures for GVHD, occurrence of grade I-II GVHD, CMV infections and types of incompatible blood group. The results showed that minor ABO-incompatible, number of mononuclear cells infused, age of patients and unrelated BMT were four important main factors influening the erythrocyte recovery. In conclusion, the erythrocyte recovery is more quick in patients with minor ABO-incompatible and more number of mononuclear cells infused, while it is slow in patents with old age and unrelated BMT.

OBJECTIVEThe study was designed to investigate the clinical characteristics and the effects of therapeutic proposal on Kawasaki disease (KD).

METHODSClinical features, diagnosis and treatment for totally 942 patients with KD hospitalized during Jan, 2000 to Dec, 2004 were reviewed. Clinical features of typical and incomplete KD were compared. Also, influential factors for KD resistant to intravenous immune globulin (IVIG) therapy were analyzed. Five hundred and ten cases were followed up for analyzing the prognosis of coronary artery lesion (CAL).

RESULTS(1) 774 cases were diagnosed as typical KD, and 168 cases as incomplete KD. The incidence of infants with incomplete KD was higher than that of infants with typical KD (18.5% vs. 10.1%, P < 0.01). As compared with typical KD, the cases of incomplete KD had a long duration of fever before final diagnosis [(7.7 +/- 2.9) d vs. (7.0 +/- 2.4) d, P < 0.01], high hemoglobin level [Hb, (106.6 +/- 13.4) g/L vs. (103.5 +/- 12.3) g/L, P < 0.01], high hematocrit [Hct, (32.0 +/- 4.3)% vs. (31.0 +/- 4.0)%, P < 0.01], and high prevalence of CAL (23.8% vs. 16.8%, P < 0.05), respectively. The occurrence rate and emerging time of clinical manifestations in incomplete KD and in typical KD were presented, respectively: non-exudative conjunctivitis [occurrence rate, 64.9% vs. 93.5%; emerging time, (4.4 +/- 1.4) d vs. (4.0 +/- 1.6) d, respectively (P < 0.05 or P < 0.01)], erythema and cracking of lips [occurrence rate, 50.6% vs. 94.8%; emerging time, (4.9 +/- 1.4) d vs. (4.5 +/- 1.6) d, respectively (P < 0.05 or P < 0.01)], rash [occurrence rate, 35.1% vs. 87.7%; emerging time, (3.9 +/- 1.9) d vs. (3.4 +/- 1.7) d, respectively (P < 0.05 or P < 0.01)], erythema and edema of extremity [occurrence rate, 26.8% vs. 71.4%; emerging time, (6.7 +/- 1.5) d vs. (5.3 +/- 1.7) d, respectively (P < 0.01)], cervical lymphadenopathy [occurrence rate, 34.5% vs. 68.0%; emerging time, (4.3 +/- 2.5) d vs. (3.6 +/- 2.2) d, respectively (P < 0.05 or P < 0.01)], strawberry tongue [occurrence rate, 31.0% vs. 59.8%; emerging time, (5.6 +/- 2.2) d vs. (4.9 +/- 1.8) d, respectively (P < 0.05 or P < 0.01)], membranous desquamation of fingertips [occurrence rate, 34.5% vs. 56.3%; emerging time, (11.7 +/- 3.3) d vs. (10.3 +/- 2.7) d, respectively (P < 0.01)], and desquamation peri-anus [occurrence rate, 42.9% vs. 50.0%; emerging time, (6.7 +/- 2.7) d vs. (6.9 +/- 2.5) d, respectively (P > 0.05)]. Except for peri-anus desquamation, other clinical manifestations in incomplete KD were sporadical as compared to typical KD. (2) Six per cent (51/857) of cases were resistant to the IVIG therapy. As compared to the group responding to IVIG therapy, high prevalence of CAL (31.4% vs. 17.1%, P < 0.05), long fever duration [(10.6 +/- 3.9) d vs. (7.5 +/- 2.3) d, P < 0.01], low Hb level [(99.9 +/- 14.1) g/L vs. (104.3 +/- 12.4) g/L, P < 0.01], low Hct [(30.1 +/- 4.5)% vs. (31.2 +/- 4.0)%, P < 0.05], low platelet [PLT, (256.9 +/- 142.4) x 10(9)/L vs. (309.7 +/- 131.5) x 10(9)/L, P < 0.05], and low albumin level [ALB, (27.8 +/- 8.4) g/L vs. (33.5 +/- 6.7) g/L, P < 0.01] were found in the group resistant to IVIG therapy, respectively. (3) In patients who received IVIG 1 g/kg and 2 g/kg, the recovery rates from CAL were 83.1% and 89.7% (P > 0.05), respectively. The prevalence of CAL in those without CAL in acute and subacute stages was 0.9% and 3.5% (P > 0.05), respectively, during 2 year-follow-up period.

CONCLUSION(1) Infants appeared to have more chances to suffer from incomplete KD. Incomplete KD had high prevalence of CAL. The peri-anus desquamation might be an important clue for early diagnosis of incomplete KD. (2) In acute stage, the influential factors for KD resistance to IVIG therapy included prolonged fever, non-elevated PLT, and persistent decrease in Hb, Hct and ALB levels. (3) Children receiving IVIG 1 g/kg and 2 g/kg had the similar effects on recovery and prevention from CAL within the first two years after KD onset.
