AIM:To study the effect of different surgeries for vision and postoperative complications in leprosy patients with lagophthalmos.METHODS:A retrospective analysis.Totally 68 leprosy patients (97 eyes) with lagophthalmos were selected who treated with different surgeries during May 2007 to September 2015 in our sanatorium.The surgeries included nylon thread correction surgery, tarsorrhaphy, temporalis transposition surgery.We observed and compared the best corrected visual acuity(BCVA) and the rate of postoperative complications, such as epiphora, lacrimal duct injury, hard to open eyes, infection at the inner and lateral canthus and scar formation of lacrimal apparatus.RESULTS:The effect on BCVA of patients treated with nylon thread correction surgery and tarsorrhaphy:the preoperative and postoperative BCVA was significantly different of the two groups (Z=-4.193,-4.213;P<0.05);the preoperative and postoperative BCVA was not significantly different of the patients underwent temporalis transposition surgery (Z=-1.532, P >0.05).The postoperative complications:(1) epiphora:there was 91% in patients underwent nylon thread correction surgery, 89% in patients underwent tarsorrhaphy, 59% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=12.198, P<0.05);(2) lacrimal duct injury:there was 66% in patients underwent nylon thread correction surgery, 95% in patients underwent tarsorrhaphy, 41% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=22.415, P<0.05);(3) hard to open eyes:there was 56% in patients underwent nylon thread correction surgery, 55% in patients underwent tarsorrhaphy, 22% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=8.795, P<0.05);(4) infections:there was 84% in patients underwent nylon thread correction surgery, 3% in patients underwent tarsorrhaphy, 11% in patients underwent temporalis transposition surgery, the difference was statistically significant (χ2=60.858, P<0.05).CONCLUSION:There are certain clinical efficacy for lagophthalmos caused by leprosy after surgery, especially patients after temporalis transposition surgery can close eyes by oneself.And their vision does not change significantly, which suggests that this surgery may prevent exposure injury for cornea.But the iatrogenic injury, the vision decrease in patients underwent other surgeries and the ocular tissue damage, such as epiphora, lacrimal duct injury, hard to open eyes, infection at the inner and lateral canthus and scar formation of lacrimal apparatus should be pay more attention to.

Objective To investigate the CT features of mesenteric lymph nodes in patients with active Crohn’s disease.Methods The CT findings in 54 patients with active Crohn's disease proved by histology were analyzed,and the anatomic distribution,size, number,shape and enhancement ratio (ER)of the mesenteric lymph node were assessed.Results Mesenteric lymphadenopathy in 38 patients (70.4%)was found with a total number of 242,83.5%(202/242)of whom were located at the mesenteric root and 16.5%(40/242) at mesenteric edge.The size of the lymph nodes at the mesenteric root was larger than that at the mesenteric edge (8.57 mm±2.26 mm versus 5.38 mm±0.1 9 mm,the mean maximum short diameter),and 73.6% (1 78/242 )of the lymph nodes were oval in shape.The lymph nodes showed significant enhancement after contrast injection with an ER of 0.53 ±0.09.Conclusion Active CD often leads to mesenteric lymphadenopathy,which is more obvious at the mesenteric root.

AIMTo analyze the response factors of different quinolone antibiotics detected by evaporative light-scattering detector (ELSD).

METHODSThe response factors of five different quinolones (enoxacin, levofloxacin, ciprofloxacin, lomefloxacin and gatifloxacin) detected by ELSD were determined by using a YMC-Pack ODS-AM cloumn (150 mm x 4.6 mm ID, 5 microns) as analytical column and 0.5% triethylamine (adjusting pH 2.5 with trifluoroacetic acid)-acetonitrile (48:12) as mobile phase at a flow rate of 0.6 mL.min-1, the temperature of the drift tube was set at 117 degrees C, and the flow of carrier gas at 3.0 L.min-1. Detector responses (A) and the amount of injection of each substance (m) were fitted to the logarithmic regression: log A = b log m + log a.

RESULTSThe linear regression equation obtained were: enoxacin: Y = 1.0799X + 2.7611, r2 = 0.9996; levofloxacin: Y = 1.0913X + 2.7235, r2 = 0.9997; ciprofloxacin: Y = 1.0828X + 2.7523, r2 = 0.9994; lomefloxacin: Y = 1.0891X + 2.7391, r2 = 0.9993; gatifloxacin: Y = 1.0878X + 2.7392, r2 = 0.9995. The differences between them were negligible.

CONCLUSIONDifferent quinolones can give the same responses with ELSD detection. So, the HPLC-ELSD methods can be applied to the determination of new substances by using another substance as reference.

Objective ① To investigate the level of the vitamin D endocrine system in peripheral relationships with bone mineral density (BMD) and the disease activity respectively. Methods The level of the 25-hydroxylate vitamin D3 (25OHD3) and 1,25-dihydroxyvitamin D3 [1,25(OH)D3] in plasma from 43 SLE patients and 44 normal controls were detected by enzyme linked immunosorbent assay. Vitamin D receptor (VDR) gene expression was determinied by real-time PCR in peripheral blood. BMD measurements in the lumbar spine (L1-4) and left proximal femur (femoral neck) were performed using dual X-ray absorptiometry before treatment. The relationship between the vitamin D endocrine system and the bone mass were studied. We also discussed the relationship between the vitamin D endocrine system and the disease activity. Results The levels of 25OHD3 and 1,25 (OH)2D3 were lower in the initial SLE patients than normal controls (P<0.01, P<0.01). The expressions of VDR gene were significantly increased in initial SLE compared with normal controls (P<0.01). The initial SLE patients had significantly lower BMD values, and higher frequency of osteopenia (35%) at both sites of measurement compared with matched healthy controls (P<0.01). The initial SLE patients were divided into two groups by BMD, abnormal group and normal group. There were no differences in 25OHD3, 1,25 (OH)D3 and VDR gene expression (P0.05). There was no correlation between the vitamin D endocrine system and BMD in initial SLE patients. There was no correlation between the vitamin D endocrine system and the disease activity either. Conclusion Vitamin D endocrine system may play an important role in SLE, but the level of VDR gene is not correlated with BMD and disease activity.
