As one of the serious complications of diabetes, diabetic retinopathy( DR) has become a main eye disease which causes blindness. The occurrence and development of DR is related to many factors. The pathogenesis is complicated, and the mechanism has not been clear. Early data suggest that the occurrence and development of DR has relations with many factors such as blood sugar level, diabetes duration and the environment. Among the factors, mitochondrial dysfunction and oxidative stress is the important mechanisms of DR and has become research focus in recent years. Consequences of mitochondrial dysfunction within cells include elevation of the rate of reactive oxygen species( ROS) production due to damage of electron transport chain proteins, mitochondrial DNA ( mtDNA ) damage, and loss of metabolic capacity. Clear understanding on the mechanism of mitochondrial functional change under high sugar level and oxidative stress response in the occurrence and development of DR is of great significance on prevention and cure of DR. ln this article, the development of mitochondrial metabolism and oxidative stress of DR is reviewed.

Objective To study the expression of major histocompatibility complex(MHC)on muscle biopsy specimens of idiopathic inflammatory myopathies(IIM),and assess diagnostic value of MHC in IIM. Methods Forty-five patients with IIM(19 polymyositis and 26 dermatomyositis)were selected for this study.Thirty healthy subjects were included as controls.Immunohistochemical staining was applied to identify the expression of HLA-A/B/C and HLA-DR on muscle biopsy-specimens in polymyositis (PM)/deFmatomyosiris (DM) patients and healthy controls.Results HIA-A/B/C antigens were expressed in muscle fibers in 18 out of 19 PM patients(95%),24 out of 26 DM patients(92%) and 3 out 0f 30 healthy controls(10%) respectively.The positive expression rate of HLA-DR in PM,DM patients and healthy controls were 84%, 81%,13%,respectively.The expressions of HLA-A/B/C and HLA-DR were significantly increased in PM and DM patients than those in healthy controls(both P<0.05),but no significant differences were found between PM and DM groups(both P>0.05).No significant correlations were demonstrated between the over-expression of HLA-A/B/C or HLA-DR and the extent of inflammatory infiltrations,muscle damage or clinical features in PM/DM groups (all P values>0.05).Conclusion MHC-Ⅰ and MHC-Ⅱover-expression in muscle fibers are the early events in PM and DM,and may occur in the absence of lymphocyte infihration and muscle damage.Immunostaining for MHC-Ⅰ and MHC-Ⅱcan be used as a routine test in the diagnosis of PM and DM.

Objective To investigate the influence of combined irbesartan/hydrochlomthiazide on morning blood pressure surge(MBPS)and left ventricular mass(LVM) in essential hypertension.Methods After 4-8 weeks' run-in period,if blood pressure wagn't up to the standard,the 120 patients were given irbesartan/hydrochlorothiazide once daily from 150 mg/12.5 mg for 12 months to 300 mg/25mg for another 12 months.MBPS was conducted by arnbuhry blood pressure monitoring(ABPM)and LVM was determined by echocardiography at the end of placebo baseline and 12 months later.Results (1)After treatment the patients with MBPS(+)decreased and patients with MBPS(-) increased.(2)After treatment the extents of MBPS were reduced in MBPS(+)patients[systolic blood pressure(SBP)difference(16.1±1.8)mm Hg(1mm Hg=0.133 kPa)vs(29.4±2.8)mm Hg,diastolic blood pressure(DBP)difference(10.2±2.3)mm Hg vs(21.2±2.2)mm Hg,P<0.01]with little change in MBPS(-)patients[SBP difference(11.2±2.4)mm Hg vs(10.1±1.2)mm Hg,DBP difference(5.9±1.9)mm Hg vs(6.8±3.2)mm Hg]compared with before treatment.(3)LVM indexes of all patients were significantly reduced.Conclusion Irbesartan/hydrochlorothiazide can effectively attenuate the extent of MBPS, and has advantages on reversing left ventricular hypertrophy.

Extracellular single-unit discharge recording technique was used to examine the effects of Ginkgolide B (BN52021) on the discharges of neurons in CAI area of hippocampal slices and to elucidate the mechanisms involved.The results showed that:(1) In response to the application of ginkgolide B (0.1,1,10 βμmol/L; n =43) into the perfusate for 2 rain,the spontaneous discharge rates (SDR) of 42/43 (97.67%) neurons were significantly decreased in a dose-dependent manner; (2) Pretreatment with L-glutamate (L-Glu,0.2mmol/L) led to a marked increase in the SDR of all 10 (100%) neurons in an epileptiform pattern.The increased discharges were suppressed significantly after ginkgolide B (1 μmol/L) was applied into the perfusate for 2 rain; (3) In 8 neurons,perfusion of the selective L-type calcium channel agonist,Bay K 8644 (0.1 μmol/L),induced a significant increase in the discharge rate of 8/8 (100%) neurons.Ginkgolide B (1 μmoL/L) applied into the perfusate inhibited the discharges of 7/8 (87.5%) slices; (4) In 8 neurons,the broad potassium channels blocker,tetraethylammonium (TEA,1 mmol/L) completely blocked the inhibitory effect of ginkgolide B (1 μmol/L).These results suggest that ginkgolide B can inhibit the electrical activity of CAI neurons.The inhibitory effect may be related to the blockade of L-type voltage-activated calcium channel and may be concerned with delayed rectifier potassium channel (KDR),which indicated that ginkgolide B play a protective role on the central neurons.

AIM:To investigate the expression and the significance of VEGF-C/D in rat cornea after alkali burning as well as the role of lymphangiogenesis in the high-risk corneal transplantation rejection.
●METHODS:The model of alkali burn corneal was made. Different times corneas were taken to electron microscope for vascularization, and examined the expression of VEGF-C/D and VEGFR-3 in l, 3, 5, 7, 14, 28d. The other rat cornea after alkali burn were divided into four parts to penetrate keratoplasty, containing only blood vessels in the cornea ( group A ) , angiogenesis and lymphangiogenesis ( group B ) , lymphangiogenesis degenerating period ( group C ) , angiogenesis degenerating period ( group D ) . ln addition, there are also normal groups ( group N ) to compare the Rl values and survival time of corneal graft.
●RESULTS: Electron microscopy showed that, when the first 7d rat cornea appeared neovascularization after alkali burn, but not lymphangiogenesis. The occurrence of new blood vessels and lymphatic in 2wk. There were no obvious lymphangiogenesis in 5wk and the angiogenesis gradually subside in 8 wk. The expression of VEGF-C/D and VEGFR-3 in the corneas of rats were up-regulated in the third days after the injury, and reached its peaks at 5d. The average survival time of group N, A, B, C, D were (14.25±0.62)d, (9.35±1.02)d, (5.06±1.13)d, (8.71±0.83) d, (9. 44±1. 05)d after transplant cornea. Compared to the rest of the group, group B plant average survival time significantly shortened (P<0. 05), while compared with group B, the survival time of A, C, D groups were significantly longer (P<0. 05).
● CONCLUSION: VEGF - C/D and VEGFR - 3 are expressed significantly after corneal alkali burn. New lymphatic vessels can accelerate high - risk corneal transplantation immune rejection.

Objective To investigate the clinical and imaging characteristics in patients with corpus callosum infarction.Methods The clinical data of 416 patients meetingthe diagnosis of cerebral infarction Were collected,in which,8 patients Were confirmed as corpus callosum infarction by MRI.Results Corpus callosum infarction accounted for 1.9% of all patients with cerebral infarction.CT scan did not show the corpus callosum infaretiom in 7 patients.The nonenhanced MRI revealed the lesions.The enhanced MRI revealed the lesion in another patient.The infarction foci were not only involved in the corpus callosum(knee,body or splenium),but also cornplicated with frontal lobe,occipital lobe and thalamus infractions.The clinical manifesta tions of the corpus callosum infarction were different due to the specific lesion sites.The simple infarction in the body of the corpus callosum mainly presented as contralateral paraparesis.atria,and left limb apra.xia;the infarction in the knee of the corpus callosum mainly presented as lower limb paralysis or contralateral paraparesis;the infarction in the splenium of the corpus callosum presented as limb paralysis and dizziness;the lacunar infarct in the corpus callosum had no obvious clinical manifestations.The patients who complicated with frontal lobe and thalamus infarction had behavioral and psychological syrnptonm,including mental retardation,language abnormalities.and incontinence.Conelusions Corpus callosum infarction is not common.MRI is the basis of diagaosis.The clinical manifestation is lack of specificity.and it is agsociated with the location of corpus callosum infarction and whether it comolicates with the infarction on other part.

Objective To study the effects of HBeAg in new born infants on the response to anti-hepatitis B immunoglobulin combined with hepatitis B vaccination.Methods Two hundred and eight infants who were born during January 2008 to January 2011 in the Department of Obstetrics in Second Affiliated Hospital of Southeast University,including 120 serum HBeAg positive infants without intrauterine infection,and 88 HBeAg negative infants as control group were recruited in the study.Infants in both groups were vaccinated with genetically engineered hepatitis B vaccine (CHO cell) 20 μg according to a standard vaccination regimen (i.e.0,1,6) and 200 IU doses of hepatitis B immunoglobulin immediately after birth and at day 15 respectively.Hepatitis B virus (HBV) serological markers and HBV DNA were measured at birth prior to immunization.HBsAg,HBeAgand hepatitis B surface antibody (anti-HBs) were detected at 1,7,and 12 months after birth to evaluate the effects of immune response.The date were analyzed by the chi-square test and groups were analyzed by t test.Results No statistical significances of anti-HBs were observed between the serum HBeAg positive group and the serum HBeAg negative group at the 1st,7th and the 12th month of birth (t=1.285,0.563 and-0.971,respectively; all P＞0.05).The anti-HBs titers in both groups at 1 month were higher than at birth (P＜0.05).At 7 months after birth,the anti-HBs titers in both groups were even higher than those at 1 month.At 12 months after birth,the anti-HBs titers in both groups were lower than those at 7 months,but still higher than those at 1 month(F=34.3959 and 64.908,respectively; both P＜0.01).Infants who were born with positive serum HBeAg were further divided into two subgroups according to the HBeAg titers,using the median HBeAg titer (47.495 S/CO) as the cut off point.Between the two subgroups,there were also no significant differences of anti-HBs at 1 month,7 months and 12 months (all P＞0.05).The HBeAg titers in HBeAg positive infants decreased gradually after birth.At 7 months,only 3 infants remained HBeAg positive.At 12 months,HBeAg turned negative in all of the 120 infants who were previously HBeAg positive,and no anti-HBe positivity were detected.Conclusion The production of anti-HBs after combined immunization with anti-hepatitis B immunoglobulin and hepatitis B vaccine in infants is independent of HBeAg serology at birth.
