Objective To evaluate the application of the lateral tarsal strip procedure for lower eyelid lesions. Methods We retrospectively analyzed 64 eyelids of 48 patients with lower eyelid laxity, ectropion, retraction, lagophthalmus and lateral canthus displacement from February 2010 to August 2013. All the patients were treated with the lateral tarsal strip procedure as the main surgical style, of which some combined with the surgery of lower-eyelid tarsal constrictor,some implanted with high porous polyethylene lower eyelid spacers (Medpor LES), and few cases of eyelid ectropion underwent transplantation or transposition of flap. The effect of relocation of lower eyelid and appearance improvement were evaluated after surgery. The degree of the low eyelid retraction, lagophthalmus and the lateral canthus displacement were examined quantitatively before and after operation, while the change of the low eyelid ectropion and laxity were done qualitatively. Results After two weeks of operation, eyelids of all the patients were relocated well except two cases of ectropion under mild correction. The quantitative evaluation showed there was significant difference between pre and post operation ( <0.001),while the qualitative effect of correction was satisfied after operation. Conclusion The lateral tarsal strip procedure had positive effects in the treatment of most sorts of lower eyelid diseases.

The reactivity of human preformed natural antibodies (PNAbs) with various porcine pancreatic cells and its isotypes was investigated. Eighteen serum samples from patients with insulin-dependent diabetes mellitus (IDDM) and 20 serum samples from healthy human subjects were collected. The frozen sections of the pig pancreas were incubated with these sera, and subsequently incubated with FITC-conjugated goat antihuman IgG and IgM monoclonal antibodies. The reactivity of human PNAbs with various porcine pancreatic cells was determined by indirect immunofluorescence staining technique. The results showed that 55.6 % of IDDM patients and 55.0 % of healthy human individuals contained PNAbs against porcine endocrine cells. However, the percentage of strongly reacting sera in the patient group was significantly increased as compared with that in the control group. All used sera from IDDM patients and 95 % of sera from healthy controls could react to one or more of the various pancreatic cell types, including: endocrine cells, exocrine cells, vascular endothelial cells, ductal epithelial cells and macrophages. The isotypes of PNAbs contained both IgG and IgM. In view of strongly positive reactivity of PNAbs with various porcine pancreatic cells, pretransplantly cross-matching test and graft pretreatment may be necessary for survival of islet transplants.

Purpose To investigate the prenatal ultrasonic features of fetal hypospadias and to compare the diagnostic accuracy.Materials and Methods The clinical data of 28 patients with suspected or confirmed hypospadias were retrospectively analyzed.The prenatal ultrasonic features,missed diagnosis and misdiagnosis of the patients were analyzed,and the diagnostic accuracy of different ultrasonic features for hypospadias was compared.Results In 28 cases,21 cases of hypospadias were confirmed by examination after birth or induced abortion with 2 cases of missed diagnosis by ultrasound,and 7 cases of non hypospadias were misdiagnosed by prenatal ultrasound.The diagnostic accuracy rate of 2D ultrasound was 67.9％ (19/28),and that of 3D ultrasound combined with 2D ultrasound was 92.9％ (13/14).The diagnostic accuracy rates of ultrasonic features such as abnormal urinary jet,abnormal urethra,tulip sign,abnormal penis tip,scrotum separation with or without penoscrotal transposition and short penis were 100.0％ (6/6),92.9％ (13/14),88.2％ (15/17),83.3％ (5/6),25.0％ (1/4) and 33.3％ (1/3),respectively.Conclusion The ultrasonic features including abnormal urinary jet,abnormal urethra,tulip sign and abnormal penis tip have great value for prenatal diagnosis of fetal hypospadias.3D ultrasound is more intuitive than 2D ultrasound and provides more details.Comprehensive analysis of all ultrasonic features is helpful for prenatal diagnosis.

Objective:To determine the molecular role of DNA methyltransferase (DNMT) in kidney tumorigenesis. Methods:Tissue samples consisted of 15 cancer tissues and 15 matched adjacent tissues from clear cell renal cell carcinoma (ccRCC) patients who had undergone nephrectomy in 2012 at the First Affiliated Hospital of Baotou Medical College, Science and Technology University of Inner Mongolia were collected. Real-time PCR, Western blot, combined bisulfite restriction analysis (COBRA) and methylation specific PCR were used in this study. Real-time PCR was used to examine the mRNA expression levels of DNMT. The global methylation level, DNA methylation level, and the expression of the antioncogene RASSF1A in ccRCC tissues were concurrently detected. Results:Both mRNA and protein levels of DNMT3B4, a splice variant of DNMT3B, were elevated in renal cell carcinoma tissue compared with those in con-troll tissue. Additionally, Alu was hypomethylated in ccRCC tissue (0.106±0.04) compared with control tissue (0.115±0.03) (P<0.05). Fur-thermore, the methylation of the promoter for RASSF1A, a tumor-suppressor gene, moderately increased in renal cell carcinoma tis-sue. By contrast, RASF1A expression decreased. Conclusion:DNMT3B4 overexpression may play an important role in human kidney tu-morigenesis via chromosomal instability and the decreased expression of RASSF1A.

Objective To observe the mechanism of action of panax quinquefolium diolsaponins (PQDS) on anti-ventricular remodeling in rats. Methods The model of pressure-loading ventricular remodeling was established through the method of rat’s abdominal aorta deligation. The male Wistar rats were divided into 5 groups,including sham operation group,remodeling model group,Benazepril group,and low and high dose groups of PQDS. The rats were treated with PQDS (with dose of 50 and 100 mg?kg-1 i.g) for 6 weeks. The rats in sham operation group and remodeling model group were treated with normal sodium (with dose of 10 mL?kg-1?d-1 i.g) for 6 weeks. The rats in masculine medicine group were treated by Benazepril (with dose of 10 mg?kg-1 i.g) for 6 weeks. After 6 weeks of treatment,myocardial morphological parameters,the content of malondialdehyde (MDA) and activity of superoxide dismutase (SOD) in serum,the contents of prostacycline (PGI2),thromboxane A2 (TXA2),nitric oxide (NO) and angiotensinⅡ (AngⅡ) in plasma were determined. At the same time,the contents of endothelium (ET) in plasma and myocardium were also determined. Results Compared with remodeling model group,the ventricular weight and cardiac coefficient were decreased significantly in the rats treated with PQDS (P0.05). Conclusion PQDS has protective effects on ventricular remodeling through increasing anti-oxidase activity,reducing the damage of free radicals and vasoactive substance on myocardium and correcting disequilibrium of PGI2/TXA2 in ventricular remodeling etc.

Objective To investigate the effects of tropicamide and esculin-digitalisglycosides combination eye drops on low myopia of children (age ranging from 6 to 14). Methods Eighty children with 160 eyes of low myopia in the outpatient department of ophthalmology of our hospital were chose from July 2010 to April 2013, then the patients were equally divided into four groups:the control, esculin-digitalisglycosides eye drops,tropicamide,and tropicamide and esculin-digitalisglycosides combination groups. The naked vision and myopia correction of each group were compared before and after treatment for two weeks, and the treatment effects were compared among four groups. Results (1) The results showed there were no significant changes before and after treatment in the control, esculin-digitalisglycosides eye drops and tropicamide groups ( >0.05); (2) On the contrast, the tropicamide and esculin-digitalisglycosides combination have significantly improved naked vision and myopia correction after 2 weeks ( <0.05);(3) Prior to the treatment,there was no significant difference among four groups (<0.05);(4) After treatment,group under tropicamide and esculin- digitalisglycosides combined was statistical different from the other groups treated with other three eye drops ( <0.05);However, there was no statistical difference among groups in these three eyedrops. Conclusion Esculin-digitalisglycosides combined with tropicamide was the most effective treatment for low myopia of children.

Objective To observe the surface electromyography (sEMG) characteristics of pharyngeal swallowing muscles in different swallowing modes in asymptomatic lacunar infarction (LI) patients. Methods From January, 2015 to January, 2017, a total of 32 asymptom-atic LI patients (LI group) aged over 60 years were consecutively collected, and 30 normal old subjects matched with age and gender (nor-mal group) were also enrolled. The amplitudes of sEMG activity of infrahyoid muscles and submental muscles in different swallowing modes were recorded, and the root mean square (RMS) was analyzed. Results Significant difference was found in both muscle groups in dif-ferent swallowing modes in both groups (F>110.67, P<0.001). There was no significance in the RMS in both two muscle groups in rest and dry swallowing modes between two groups (t<1.484, P>0.05). In the 20 ml water swallowing mode, the RMS was lower in the submental muscles in the LI group than in the normal group (t=3.334, P<0.01), and no significant difference was found in the infrahyoid muscles (t=1.871, P>0.05). In the 100 ml continuous drinking mode, the RMSs were significantly lower in both two muscle groups in LI group than in the normal group (t>3.118, P<0.01). Conclusion Swallow abilities decrease in asymptomatic LI. sEMG could be used to evaluate their swallowing function.

[Objective]To explore the efficacy of T2* mapping for evaluating inflammatory activity in the patients with Crohn disease(CD).[Methods]A total of 98 CD patients underwent MR enterographywith T2*WI. T2* values were measured by put-ting regions of interest on the thickening bowel wall on T2*mapping. The activity of bowel segment was scored by magnetic resonance index of activity(MaRIA),to analyze the relationship between T2*values with CD activity.[Results]A total of 160 bowel segments were evaluated and includedinactive(MaRIA<7,n=26),mild(7≤MaRIA<11,n=23),and moderately-severe(MaRIA≥11, n = 111)active lesions. The differences in T2* values amongthese three groups were significant(all P < 0.05). T2* values of 160 bowel segments correlatedclosely withMaRIA(r=0.743,P<0.05). High accuracy of T2*values was shown for differentiating inac-tive from active CD(AUC=0.877)anddifferentiating inactive-mild from moderate-severe CD(AUC=0.848). The threshold T2*value of 20 ms allowed differentiation of mild from moderate-severe CD with74.5%sensitivity and 84%specificity.[Conclusions]T2*values, as thequantitative indexof T2*mapping,correlate well with CD activity and showsatisfiedefficacy for diagnosing inflammatoryactivity.
