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.

Objective To study the serum level of brain natriuretic peptide (BNP) and atrial natriuretic peptide (ANP) in patients with congestive heart failure (CHF) and assess the value of BNP. Methods The serum levels of BNP and ANP were determined by enzyme- linked immnoabsorbent assay.Cardial mdex(CI)and left ventricular election fraction(LVEF)in heart failure stage and period recouery of children with heart failare were determined by Doppler ultrasonography cardiogram. Results The BNP serum levels began to increase before heart failure (P

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.

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.

Objective To analyze the clinical significance of elevated serum carbohydrate antigen 724 (CA724) in gout patients. Methods The clinical data of 271 gout patients, 63 ankylosing spondylitis patients, 40 psoriatic arthritis patients, 67 osteoarthritis patients and 280 healthy controls in our hospital from Jul. 2016 to Jun. 2019 were retrospectively analyzed. The positive rates and levels of serum CA724 were compared among gout patients and ankylosing spondylitis patients, psoriatic arthritis patients, osteoarthritis patients and healthy controls. According to the clinical symptoms and signs, gout patients were also divided into acute-stage group (n=53) and chronic-stage group (n=218); the serum CA724 levels were compared between the two groups and the correlation between serum CA724 level with white blood cell count and C-reactive protein (CRP) was analyzed in acute-stage gout patients. According to the serum CA724 level, gout patients were divided into elevated serum CA724 group (n=63) and normal serum CA724 group (n=208), and the serum uric acid, triglyceride, and high-density lipoprotein were compared between the two groups. Results The positive rate of serum CA724 in gout patients was significantly higher than those in ankylosing spondylitis patients, psoriatic arthritis patients, osteoarthritis patients and healthy controls (P<0.05, P<0.01). Serum CA724 in gout patients was significantly higher than those in osteoarthritis patients and healthy controls (P<0.05, P<0.01). Serum CA724 in acute-stage gout patients was significantly higher than that in chronic-stage gout patients (P<0.01), and it was positively correlated with white blood cell count and CRP (both P<0.01). The levels of serum uric acid and triglyceride in gout patients with elevated serum CA724 were significantly higher than those in patients with normal serum CA724 (P<0.01, P<0.05), while the level of high-density lipoprotein was significantly lower than that in normal serum CA724 group (P<0.01). Conclusion Serum CA724 level is increased in some gout patients, and serum CA724 is correlated with acute gout attack and inflammation.

Objective To evaluate the neuroprotective effect and safety of neonatal hypoxic-ischemic encephalopathy(HIE)treated with recombinant human erythropoietin(rhEPO).Methods Fifty-three neonates with HIE were randomly divided into rhEPO treated group(n=29) with the dosage of 300 U/(kg?time),three times a week for 2 weeks and control group(n=24)without rhEPO.All supportive measures were same between 2 groups.Neurological scoring was evaluated at d3,d5 and d7 Neonatal behavioral neurological assessment(NBNA) was evaluated at d7,d14 and d28.The neurodevelopment quote was evaluated at age of 3 and 6 months.Blood pressure,liver and renal function,blood electrolytes and blood hemoglobin,platelet and reticular red blood cell count were monitored before and after treatment in all infants.Results The neurological scoring between two groups had no difference at d3.The significant difference was found at d7(P0.05).Conclusions Teraphy with rhEPO on neonatal HIE infants can promote neurological recovery,and there is no serious side effect with rhEPO treatment.

3T3-LI preadipocytes were induced to differentiate and 3T3-L1 adipocyte or preadipocytes were incubated with oleate or palmitate overnight.RT-PCR was used to measure adiponectin receptor(AdipoR)1 and AdipoR2 mRNA levels.The results showed that the AdipoRl and AdipoR2 expressions were differentiation- dependent.Oleate only suppressed AdipoR mRNA expression in preadipocyte but not in adipocyte.However,high concentration of palmitate reduced AdipoR mRNA expression in both 3T3-LI preadipocyte and adipocyte.
