AIM:To observe the situation of rat retinal tissue DNA damage at early diabetic period, discuss the role of the blood glucose fluctuations, and provide a new method for studying the pathogenesis of diabetic retinopathy ( DR) .
METHODS: SD rats were randomly divided into four groups:normal control group (NC), normal fluctuation group ( NF ) , diabetes group ( DM ) and diabetes fluctuation group ( DF ) . Diabetic models were established through intraperitoneal injection of STZ. A certain amount of glucose was injected in the rats of group NF and DF in an intraperitoneal mode three times a day after the model was established, thereby causing blood glucose fluctuations. Rats were killed and the retinal tissues were taken in the 8th week. Single cell gel electrophoresis ( SCGE ) technique was adopted for detecting DNA injury extent in the retina tissue.
RESULTS:Groups NF and DF showed significant and regular fluctuations. The curve of blood glucose fluctuations was relatively stable. All values of MBG, SDBG, LAGE and M were significantly increased compared with group NC. Group DF was increased more significantly. It was statistically significant (P<0. 01). SCGE showed that there were DNA damages in different levels in the cells of group NF, DM and DF. Indicators of cells such as TL, TDNA %, TM, OTM were higher than that in group NC. It was statistically significant ( P<0-01). The comparison difference between two groups was also significant (P<0. 01).
CONCLUSION: Rat retinal tissues have DNA injury during early diabetic period. DNA injury is gradually aggravated with blood glucose fluctuation. It indicates that high blood glucose and blood glucose fluctuation are involved in the mechanism of cell DNA injury, and they may be one of DR early event, have played a certain role in the incidence of DR.

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.

The study on the Rauvolfia verticillata (Lour.) Baill., which belongs to Apocynaceae, was carried out to look for its chemical constituents and pharmacological activity. The isolation and purification were performed by chromatography on silica gel, Sephadex LH-20 and ODS (octadecyl silane) open column. The structures of obtained compounds were elucidated on the basis of physicochemical properties and spectral analysis. Three indole alkaloids and one acridone alkaloid were isolated from chloroform layer extract and identified as ajmalicine B (1), sandwicine (2), raunescine (3) and 7-hydroxynoracronycine (4) separately. Ajmalicine B (1) is a new compound belonging to indole alkaloid. Compound 4 as an acridone alkaloid was a new type compound isolated from Rauvolfia genus for the first time. We also did some biological activity research on the new type compound (4) to explore other pharmacological activities in addition to antihypertensive activity.

Objective To build predictive model of secondary mild cognitive impairment (MCI) in patients with painful diabetic neuropathy (PDN), and analyze its apply. Methods The patients with PDN were consecutively selected from March 2013 to March 2016. The relevant clinical data were recorded, and the patients were followed up for 1 year. According to the results of follow-up, secondary MCI risk indicators were predicted, and the time window of adverse outcomes event was validated. Results A total of 82 PDN patients completed the study, and secondary MCI occurred in 16 cases. Sixty-six cases had not secondary MCI. The Cox regression model multivariate analysis results showed that the independent influencing factors of secondary MCI was course of PDN, brief pain inventory (BPI) score and neuron-specific enolase (NSE) in patients with PDN (HR = 1.238, 1.336 and 1.450; P<0.05). The secondary time window of the MCI in PDN patients with the course of PDN ≥3.367 years, BPI score≥4.704 scores and NSE ≥ 7.420 μg/L was shorter, in whom BPI score and NSE had a higher evaluation ability. Conclusions The courses of PDN, BPI score and NSE are independent influencing factors of secondary MCI in PDN patients, and the BPI score≥4.704 scores and NSE≥7.420μg/L have a higher evaluation ability.

Objective To investigate the clinical significance of anti-cyclic citrullinated peptides antibodies (anti-CCP) in systemic lupus erythematosus (SLE) patients with arthritis.and to explore the association of anti-CCP with erosive arthritis in SLE patients.Methods Serum samples from 138 SLE patients were examined for anti-CCP with the second generation anti-CCP detection commericial kit.The association between anti-CCP antibodies and clinical features as well as laboratory parameters.especially arthritis,in these SLE patients were analyzed.Results The frequency of anti-CCP was 13.8% (19/138) in this group of SLE patients.Seventy of 138 SLE patients had experienced arthritis.of whom 14 were anti-CCP positive.Anti-CCP antibodies were more frequently detected in SLE patients with arthritis than those without arthritis (20% vs 7.4%,P＜0.05).A statistical correlation between anti-CCP and rheumatoid factor (RF) was found in SLE patients with arthritis (r=0.36,P=0.002).The frequency of arthritis was significantly higher in SLE patients with anti-CCP than without (73.7% vs 47.1%,P＜0.05).Eight out of 138 SLE patients showed ioint erosions on radiographs.When compared with anti-CCP negative patients,erosive arthritis occurred more often in anti-CCP positive patients (35.7% vs 5.4%.P＜0.001).Interestingly.two patients without anti-CCP and RF but with erosive arthritis were anti-RA33 antibodies positive.All 8 SLE patients with erosive arthritis in our study fulfilled 1987 ACR criteria for RA.With regard to other clinical and laboratory features.there were no differences between SLE patients with or without arthritis or between patients with positive and negative anti-CCP antibodies.Conclusions Anti-CCP antibodies have a prevalence of 13.8% in our group of SLE patients and its presence is closely associated with arthritis.Moreover,the presence of anti-CCP antibodies may be a good marker to predict the outcome of SLE arthropathy.
