1.Application value of FFA and OCT in diagnosis of central retinal artery and vein occlusion
International Eye Science 2016;16(10):1946-1948
AIM: To investigate the clinical value of fundus fluorescein angiography ( FFA ) and optical coherent tomography ( OCT) in the diagnosis of central retinal vein occlusion.
●METHODS:A total of 47 cases (47 eyes) central retinal vein occlusion were retrospectively analyzed from Jun. 2012 to Dec. 2015 in our hospital ophthalmology center. According to the final diagnosis, the results were divided into 21 cases of central retinal artery occlusion ( group CRAO, 21 eyes) and central retinal vein occlusion ( group CRVO, 26 eyes ) . All patients received FFA and OCT examination within 2wk of onset, and the image data of the two kinds of examination results were analyzed.
● RESULTS: Group of patients with CRAO average macular foveola thickness, angle measuring, filling time determination results were significantly lower than that of the patients with CRVO group average and the differences were significant (P<0. 05).
●CONCLUSION:FFA and OCT images of central retinal artery and vein occlusion have their own characteristics, and the combination of these two images can be used to identify and diagnose the central retinal artery and vein occlusion.

Infection and inflammatory response can induce the brain damage in neonate,but the mechanism involved in it has not been elucidated completely.Proposed mechanisms include inflammatory response,cytokine and free radical-mediated injury,and excitatory amino acids-induced injury.The activation of microglia and selective vulnerability of immature oligodendrocyte play an important role in the whole process.Recent researches show that the fetal inflammatory response and complex gene regulation are also involved in the infection-induced brain damage.

Journal of Zhejiang University. Medical sciences 2012;41(4):453-463
Gastrointestinal tract carcinoma is one of the leading causes of cancer-related death in China. Chemoprevention has been considered as a potential approach to control this type of disease. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a redox-sensitive transcription factor that protects cells from oxidative/electrophilic stresses by activating the expression of a battery of cytoprotective genes through the antioxidant response element (ARE). Recently, Nrf2 has emerged as a novel target for chemoprevention. Several natural or synthetic chemicals, which activate Nrf2/ARE signaling pathway, have showed effect in animal models, and promises in many ongoing clinical trials. This review summarizes the recent findings on the regulation of Nrf2/ARE signaling pathway, and the developments in both preclinical and clinical studies.

OBJECTIVETo investigate the characteristics, diagnosis, and treatment of ovotesticular disorder of sex development (OT-DSD).
METHODSWe retrospectively analyzed 2 cases of OT-DSD treated in our hospital. The patients were 19 and 15 years old, respectively, and both received systematic physical examination and examinations of the karyotype, sex hormone, adrenocorticotropic hormone (ACTH), color Doppler ultrasonography, urethrocystoscopy, and human chorionic gonadotropin (HCG) test. Under the laparoscope, we performed surgical gonad exploration, gonadectomy, and vulvar orthopedics. Intraoperative exploration and pathology confirmed true hermaphroditism in both cases, with sex selection as female. One underwent laparoscopic resection of the ovotestis, and the other removal of the testis with the ovarian tissue reserved.
RESULTSThe patients were followed up for 12 months postoperatively, which found no abnormality in either the vulvas or the genital glands.
CONCLUSIONSurgical exploration of the gonad is the only method for the diagnosis of OT-DSD and sex selection is the key to treatment. Laparoscopic surgical exploration of the gonad and vulvar orthopedics are the first treatment options.

OBJECTIVETo compare therapeutic effects between unilateral decompression technique only and open decompression technique with fusion and internal fixation for the treatment of lumbar spinal stenosis.
METHODSFrom March 2008 to February 2011, 82 patients with lumbar spinal stenosis were treated with operations, and divided into two groups. There were 13 males and 19 females in group A, with a mean age of (56.31±4.31) years old. The patients in group A were treated with unilateral decompression via fenestration technique only, including 23 patients obtaining single level decompression and 9 patients obtaining two levels decompression. In group B, there were 18 males and 32 females, with a mean age of (57.53±4.28) years old. The patients in group B were treated with open decompressive technique with fusion and internal fixation, including 38 patients obtaining single level decompression and 12 patients obtaining two levels decompression. The VAS of back pain and leg pain, ODI were recorded before and after surgery to evaluate low back pain,leg pain and walking tolerance.
RESULTSAll the patients were followed up, and the duration ranged from 10.9 to 43.4 months,with a mean of 32.8 months. There were no differences in age, stenosis level, VAS of back and leg pain and ODI before surgery between two groups. Compared with the corresponding ones in group B, the operation time, blood loss, hospitalization time,recovery time of routine daily life and finacial expenditure of patients were all shorter or less in group A. There was no statistically difference in complications between two groups.
CONCLUSION"Unilateral decompression via fenestration technique" is a less invasive and more effective decompressive technique for degenerative spinal stenosis without posterior elements damage. It has advantages in operation time, blood loss, hospitalization time, recovery to daily life and financial expenditure. When controlling the operative indications strictly, the technique could be an important procedure for surgical treatment of degenerative spinal stenosis, especially in the elderly population.

It has been showed that there were obvious obstacle effects of Panax notoginseng replanting. Crop rotation was the main effective technique to overcome the obstacle. To find a reasonable crop rotation system for P. notoginseng, aqueous extracts from root, stem and leaf of P. notoginseng were analyzed for allelopathic effect on three maize varieties (which are often grown in regions where P. notoginseng grown). The main results were as follows: (1) Allelopathic effect of P. notoginseng stem and leaf extracts on the three other tested plants was stronger than that of root extracts; (2) Corn was more vulnerable to the effects of allelochemicals at seedling stage than at germination stage, and the corn root was more sensitive than aerial part to allelochemicals; (3) Lusan No. 3 and Yunrui No. 1 showed resistance to P. notoginseng allelopathy, with respective comprehensive sensitivity indexes (M3) of - 0.089 3 and -0.159 2, while Bainuo No. 1 is sensitive at M3 = -0.261 0. It then can be concluded that Lusan No. 3 and Yunrui No. 1 may be an alternative rotation plants for overcoming P. notoginseng continuous cropping obstacle.
