Background Recently,the study on the cause of optic nerve damage induced by glaucoma is of concern in ophthalmology.Some research showed that the immune system is associated with glaucoma-induced optic neuropathy.Acute ischemia-reperfusion is an ideal model of studying optic neuropathy.ObjectiveThe present study investigates the effect of T and B lymphocyte deficiency on the retinal neurocytes of mice with acute intraocular hypertension.Methods Sixteen SPF CB-17/Icr.Cg-Prkdc~(scid)Lyst~(bg)/CrlVR mice 6-8 week-old (severe combined immunodeficiency mouse,SCID) were used in this study and 16 age-matched SPF wild type (C57BL/6) mice served as controls.The ischemia-reperfusion injury models were induced in the right eyes of 10 SCID mice and 10 C57BL/6 mice through intra-anterior chamber infusion of balanced saline solution for 45minutes to increase the intraocular pressure to 104mmHg,and the left eyes served as model controls.The other 6 SCID mice and 6 C57BL/6 mice served as normal control group.10g/L (2μL) of FlouroGold was injected into the brains of the mice for the labeling of surviving retinal ganglion cells 21 days after ischemia-reperfusion.The thickness of retinal inner nuclear layer was measured by H&E staining under the fluorescent microscope 21 days after ischemic insult.The use of the animals followed the Standard of Association for Research in Vision and Ophthalmology.Results In normal control mice,the morphology of retinal ganglion cells (RGCs) and retinal structure were similar between SCID mice and C57BL/6 mice.The differences in the numbers of RGCs and retinal thickness were insignificant between the two types of mice(P＞0.05).In the experimental mice,the surviving RGCs were strikingly increased in SCID mice (91%±5%) compared with C57BL/6 mice(78%±5%)(P=0.003).The thickness of the retinal inner nuclear layer was obviously thinner in the model eyes (22.44±1.70μm) compared to model control eyes (31.06±3.75μm) in C57BL/6 mice(P=0.004),but no statistically significant difference was found between the model eyes and model control eyes in SCID mice (33.52±2.13μm vs 34.06±3.00μm) 21 days after ischemia-reperfusion injury(P＞0.05).Conclusion T and B lymphocytes deficient mice show a better tolerance to acute intraocular hypertension than the wild type C57BL/6 mice.

Background The biomeasurement and imageology of retinal nerve fiber layer(RNFL) thickness showed the damage of retinal structure in the early and middle stage of glaucomatous eye,however,the subtle functional damage of glaucoma can not be timely reflected only with automatic static perimeter.Microperimetry is a method of quantitatively assessing mean sensitivity (MS) of macular zone.Objective This study was to evaluate and compare the macular functional change in early and middle stage of primary open angle glaucoma (POAG) and chronic angle-closure glaucoma (CACG) with MP-1 microperimeter.Metbods This trail protocol was approved by Ethic Committee of Peiking University Third Hospital,and written informed consent was obtained from each subject prior to entering the study group.A cross-sectional and case-controlled study was designed.A total of 126 eyes from 126 subjects were enrolled in the trail,including 53 eyes of 53 normal subjects,50 eyes of POAG patients and 23 eyes of CACG patients.A macular 10° program was set with MP-1 microperimetry to record the MS of various subareas.The macula was zoned into central 2°,6°,and 10° visual fields and 4 quadrants in each ring.The MS of different rings and subareas was detected and compared among POAG patients,CACG patients and normal controls.Results The MS values of central 2°,6°,10° and whole macular area were (15.09 ± 3.03),(15.72 ± 3.22),(13.99 ± 3.63) and (14.91±3.07)dB in the POAG group,which were significantly lower than those of (17.29±1.59),(18.05±1.24),(16.76±1.89) and (17.37±1.46)dB in the normal control group (all at P=0.000).The MS values of central 2°,6°,10° and whole macular area was (16.00±2.39),(15.83±2.63),(14.45±3.15) and (15.42±2.54) dB in the CACG group,and the reduced MSs were seen at the 6°,10° rings and whole macular area in the CACG group compared with the normal control group (P =0.004,0.013,0.011).Within the 6° ring,the MS values in the inferotemporal quadrant were declined in the POAG group and CACG group compared with the normal control group (P =0.000,0.022),but the difference was not statistically significant between the POAG group and the CACG group (P =0.311).In addition,the MS value in the inferonasal quadrant was significantly lower than that of the normal control group (P =0.005); while that in the CACG group was not significantly different in comparison with the normal control group (P=0.119).In the POAG group,the MS value of the inferotemporal quadrant was significantly lower than that of the superonasal or superotemopral quadrant (P =0.043,0.016),but no significant differences were found among the 4 quadrants in the CACG group (all at P＞0.05).Conclusions The mild damage of retinal function appears in the early and middle stage of POAG and CACG.More serious MS reducing occurs in the inferotemporal and inferonasal quadrants of POAG.

Objective To discuss effect on prevention of postpartum hemorrhage of caesarean section by us- ing calcium gluconate combined with oxytocin and misoprostol.Methods 385 cases of caesarean section were select- ed and randomized into O(Oxytocin) group and OM(Oxytocin+ Misoprostol) group and COM (Calcium gluconate+ Oxytocin+Misoprostol)group.Results The mean operative blood loss in O group and OM group and COM group were (300?50.24)ml,(220?30.83) ml,(150?45.52) ml.The amount of the mean operative blood loss of COM group was significantly lower than those of O group and OM group(P＜0.05).The amount of bleeding of 2 hours after delivery in O group and OM group and COM group were (400?45.52)ml,(260?60.43)mi and(210?50.54) ml.The amount of bleeding of COM group was significantly lower than those of O group and OM group (P＜0.05).Conclusion The prevention by used calcium gluconate combined with oxytocin and misoprostol is efficient in reducing the amount of postpartum hemorrhage of caesarean section.The operation of medicine is easy and safe and economic.

OBJECTIVETo evaluate the efficacy and safety of Jinying Capsule (JC) in treating pelvic inflammatory disease patients with accumulated damp-heat syndrome (ADHS).

METHODSTotally 328 patients were recruited in a prospective, positive drug parallel controlled, and multi-center clinical trial. Of them 213 patients in the treatment group took JC (0.5 g per capsule), 4 capsules each time, 3 times per day, while 115 patients in the control group took Kangfuyan Capsule (KC, 0.4 g per capsule), 3 capsules each time, twice per day. The course of treatment was 4 weeks for all. Scores of Chinese medical syndromes, visual analogue scale (VAS) of the lower abdominal pain, and European quality of life-five dimension scale (EQ-5D) were observed before treatment and after 4 weeks of treatment.

RESULTSThere were 204 patients in the treatment group and 109 in the control group who completed this trial. The total effective rate of Chinese medical syndrome was 89.71% (183/204 cases) in the treatment group and 76.15% (83/109 cases) in the control group (P < 0.01). Compared with before treatment in the same group, EQ-5D scores increased, and VAS scores of the lower abdominal pain decreased in the two groups after treatment. EQ-5D scores was 0.857 ± 0.157 in the treatment group, obviously higher than that in the control group (0.753 ± 0.126, P < 0.05). VAS scores of the lower abdominal pain was 2.14 ± 1.23 in the treatment group, lower than that in the control group (2.33 ± 1.24), but with no statistical difference between the two groups (P > 0.05). No adverse reaction occurred in the two groups.

CONCLUSIONJC was superior to KC in improving Chinese medical syndrome and quality of life of pelvic inflammatory disease patients with accumulated damp-heat syndrome.
