OBJECTIVE:To observe clinical efficacy and safety of Autoserum eye drops in the treatment of filamentary kerati-tis after excimer laser corneal refractive surgery. METHODS:46 patients (90 eyes) with filamentary keratitis after excimer laser corneal refractive surgery were selected and randomly divided into control group and observation group with 23 cases(45 eyes)in each group. The control group was given clearing mesh+wearing soft contact lens+bFGF eye drops;the observation group was giv-en clearing mesh+ wearing soft contact lens + Autoserum eye drops. The clinical efficacy,cure time,recurrence rate and ADR were compared between 2 groups. RESULTS:The total effective rate of observation group was 93.3%,which was higher than that (82.2%)of the control group,with statistical significance(P<0.05);the cure time of observation group was(2.7±1.1)d,which was shortened significantly compared with control group [(3.5±1.2)d],with statistical significance(P<0.05). The recurrence rate of filamentous keratitis was 4.4% in observation group and 15.6% in control group;the observation group was significantly lower than the control group,with statistical significance(P<0.05). During the treatment,there were 1 case(1 eyes)of corneal epitheli-al edema in observation group and 2 cases (2 eyes) of corneal epithelial edema in control group,there was no statistical signifi-cance(P>0.05). CONCLUSIONS:In the treatment of filamentous keratitis after excimer laser corneal refractive surgery,therapy of clearing mesh+wearing soft contact lens+Autoserum eye drops have high total effective rate,low recurrence rate and short cure period with less ADR.

Objective To compare and analyze differences in clinical characteristics, auxiliary examination and im?munotherapy between children with anti-N-methyl-D-aspartate(NMDA) receptor encephalitis and adults. Methods Clinical data was retrospectively collected from 34 cases anti-NMDA receptor encephalitis. All people were divided into the child group and the adult according to the age of onset and the inpatient department. Score of Modified Rankin Scale (mRS) before and after treatment and follow-up period (6 months~24 months) were compared to estimate the neurologi?cal outcomes. Results Data from 34 patients including 19 children and 15 adults was analyzed. Hypoventilation, epilep?sy and status epilepticus were more common in the adult group than in the child. The positive rate of EEG delta brush was higher in child group than in adult group. Two women were complicated by suspicious ovarian teratoma. Intravenous immune globulin was used commonly in the child group, while the plasma exchange or immunosuppressant used common?ly in the adult group. Time of onset to hospital admission and final diagnosis were shorter in the child group than in the adult. Patients requiring ICU were fewer in the child group than in the adult. The scores of mRS were significantly lower in the child group than in the adult at hospital discharge (P<0.05). Conclusion Clinical characteristics is more compli?cated in adults with anti-NMDA receptor encephalitis compared with children including a worse disease severity and a poorer short-term outcome.

Objective To investigate the relationship between Sfrp5 and T2DM macroangiopathy , and to evaluate the activation of calcium dobesilate. Methods T2DM patients were divided into experimental group (IMT≥0.90 mm,n = 65)and control group (IMT < 0.90 mm, n = 30)and patients in experimental group were randomly further divided into group A (n = 30,treated with calcium dobesilate) and group B (n = 35, treated with routine therapy). Another 20 healthy control were involved as normal group. Sfrp5,IL-10,TC,TG,FPG, HbA1c and IMT were observed before and after treatment. Results Sfrp5 and IL-10 in experimental group and control group were lower than those in normal group (P < 0.01)and Sfrp5 and IL-10 in experimental group were lower than those in control group (P < 0.05). Correlation analysis showed that sfrp5 and IL-10 were negatively correlated with these above-mentioned indicators and Sfrp5 was positively correlated with IL-10(P < 0.05). After 16-week treatment, the contents of FBG, lipid, HbA1c and IMT were decreased in group A and B, but Sfrp5 and IL-10 were increased in group A (P < 0.01). Sfrp5 and IL-10 didn't alter significantly in group B (P >0.05). IMT in group A were decreased when compared with group B (P < 0.05). Conclusion Sfrp5 is negatively correlated with macroangiopathy. Calcium dobesilate can elevate Sfrp5 and IL-10,thus delay the progression of macroangiopathy.
