? AlM: To examine choroidal thickness and its relationship with axial length and spherical equivalent by spectral domain optical coherence tomography ( SD -OCT ) in patients with myopic choroidal neovascularization ( mCNV) .
?METHODS: We prospectively recruited 30 cases of mCNV in Beijing Anzhen Hospital from October 2010 to December 2014. SD-OCT was used to measure choroidal thickness subfoveally and at 1. 5mm superiorly, inferiorly, nasally and temporally ( SFCT, SCT1. 5mm , lCT1. 5mm , NCT1. 5mm , TCT1. 5mm ) . Paired t- test was conducted to assess the difference of spherical equivalent, axial length and choroidal thickness between mCNV group and controls. Logistic regression analysis was performed to evaluate the correlation between spherical equivalent, axial length, choroidal thickness and mCNV.
?RESULTS: The difference of spherical equivalent and axial length between mCNV group and controls was not significant (P>0. 05). lnferior was decreased in mCNV group compared with controls (140. 85±33. 46μm vs 168. 95±45. 36μm). The difference was significant (P=0. 008). Logistic regression demonstrated that decreased choroidal thickness ( lCT1. 5mm ) at inferior location was associated with mCNV (OR=2. 12;95%CI 1. 35~3. 28;P=0. 02).
?CONCLUSlON: The decrease of lCT1. 5MM may be one of the risk factors of mCNV.

Objective To explore the clinical effects of enema combined with massage therapy on jaundice in premature infants.Methods Seventy-five premature infants with jaundice were randomly divided into 3 groups,enema combined message therapy group(group A),abdominal massage therapy group(group B),and double-side phototherapy group(group C).All 3 groups were received the same formula fee-ding,intravenous nutrition and identical drug treatment.Group A was given enema with mixed kaiselu and normal saline together with 60 times clockwise abdominal massage once a day for 2 weeks.Group B only received abdominal massage twice per day for 2 weeks.Transcutaneous bilirubin(TB) indexes of all the premature infants in the 3 groups were detected and transformed into total TB concentrations every morning,through version of MINOLTA JM-102 transcutaneous bilirubin radiometer made in Japan.When TB index counted more than 196.58 ?mol/L,group A and B were given single-side phototherapy for 24 hours.Neither enema nor abdominal massage was given to group C,and double-side phototherapy was applied when TB indexes were above 196.58 ?mol/L.Daily TB indexes,duration of jaundice and phototherapy,time of meconium exhaustion,defecation times in each day,incidence of constipation and feeding intolerance were recorded.Results Duration of jaunhospitalized and phototherapy were significantly shortened in group A compared with those of the other groups.In 34 premature infants who were hospital for at least 2 weeks,TB indexes in group C were lower than those in group B on the 9th day.On the 12th day and the 14th day,TB indexes in group A and C were lower than those in group B(Pa

Objective Inquire into the relationship between diabetic peripheral neuropathy(DPN)pathogenic factor and Antigangliosides antibody(Anti-GS-Ab)in type 2 diabetes mellitus. Methods It was examined by enzyme-linked immunosorbent assays(ELISA)to the levels of serum Anti-gangliosides(Anti-GS)in 2 DM and DPN as well as healthy.Results The positive rate of Anti-GS-IgM,IgG in DPN group were 46.7% and 20.0%.repectivily it was obviously higher than normal group and 2 DM group.Conclusion The relationship between the DPN and Anti-GS-Ab is a close.It show that Anti-GS-Ab play an important role in DPN pathological process.

Objective To observe the effect of ethanol extract and ethyl acetate extract of Capparis Spinosa on the thickness of dermis,synthesis of collagen type Ⅰ,type Ⅲ,and expression of transforming growth factor-β1 in mouse models of scleroderma.Methods Mouse models of scleroderma were established through local injection of bleomycin on the back once a day for 4 weeks.After confirmation of model establishment,72 mouse models were equally and randomly divided into three groups.Two groups received topical treatment with ethanol extract of Capparis Spinosa and ethyl acetate extract of Capparis Spinosa,respectively,no treatment was given to the rest of the control group.After 2-,4-,6-week treatment,8 mice were sacrificed and tissue samples were obtained from the back,and subiected to the measurement of dermal thickness by HE staining,as well as to the analysis of expression of collagen type Ⅰ,collagen type Ⅲ and transforming growth factor-β1 by immunohistochemical staining.Results On week 2,4,6,the thickness of dermis was 23.22,24.94,19.97 μm respectively in mice treated with ethanol extract of Capparis Spinosa,27.66.26.15,22.13 μm respectively in those treated with ethyl acetate extract of Capparis Spinosa.Compared with the mouse models without treatment,the thickness of dermis significantly decreased(F=12.99,P＜0.01),the expression of collagen type Ⅰ(F=7.47,P＜0.01)and transforming growth factor-β1(F=11.76,P＜0.01)were also inhibited in those receiving treatment.However,the expression of collagen type Ⅲ was not affected obviously by the treatment.Conclusion The ethanol extract and ethyl acetate extract of Capparis Spinosa have the effect against skin fibrosis.

Objective To study the dynamic changes and potential impacts on the voice in postoperative pa-tients with different types of thyroid operation.Methods A total of 48 cases thyroidectomy,34 with thyroid isth-mus and lobectomy and 4 with total thyroidectomy,and 19 cases neck operation were included in this study for the examinations of electric laryngoscope,and acoustic voice analysis preoperative and postoperative,respectively.The characteristics of the acoustic parameters were analyzed.Results Vocal cord paralysis and cricothyroid joint disloca-tion in all the patients before and after operation were not observed.For male patients in the experimental group, postoperative parameter values of F0TD were higher than the day before surgery and 30 days after thyroidectomy. The difference was statistically significant (P <0.05 ).In female patients,postoperative parameter values of F0 were lower than the day before surgery and 2nd,7th,and30th day after thyroidectomy.Postoperative parameter values of Jitter for 30th day were lower than 1st day after the operation.The postoperative parameter values of F0TD for 1st,2nd,3rd,and 7th day were higher than the day before thyroidectomy.The parameter value of F0TD was lower than 1st day after surgery,and the postoperative parameter value of HNR for 30th day was lower than 3rd day after the thyroidectomy.The difference was statistically significant (P <0.05 ).Compared to the control group,there were no significantly differences in male patients of experimental group before and after the surgery(P >0.05).The parameter values of F0 in famale patients before the thyroidectomy,the 1st,2nd,3rd,7th day after the surgery and the parameter value of Jitter,Shimmer,HNR for 1st day after the operation were significantly dif-ferent(P <0.05).There were no significant differences in all parameter value of 30 days after thyoidectomy(P >0. 05).Conclusion Voice parameter values alter in a way after thyroid surgery without apparent recurrent laryngeal nerve injury,especially in the female patients.The improvement of voice acoustic parameters can be observed on the 30th day after operation.

OBJECTIVE: To determine the chlorpyrifos in human blood by liquid chromatography-tandem mass spectrometry and to validate its application in poisoning cases. METHODS: The samples were extracted by a simple one-step protein precipitation procedure. Chromatography was performed on a Capcell Pack C18 MGII column (250 mm x 2.0 mm, 5 μm) using an isocratic elution of solvent A (0.1% formic acid-water with 2 mmol/L ammonium acetate) and solvent B (methanol with 2 mmol/L ammonium acetate) at 5:95 V:V). RESULTS: The linear ranged from 5 to 500 ng/mL (r = 0.998 7). The limit of detection (LOD) and the lower limit of quantification (LLOQ) were 2 ng/mL and 4 ng/mL, respectively. For this method, the precision and accuracy of intra-day and inter-day were < 10% and 97.44%-101.10%, respectively. The results in stability test of long-term frozen were satisfied. The matrix effect, recovery and process efficiency were 64.97%-86.81%, 76.70%-85.52%, and 55.57%-66.58%, respectively. CONCLUSION This method can provide a rapid approach to chlorpyrifos extraction and determination in toxicological analysis of forensic and clinical treatment.
