AIM: To explore the curative effect of different ways of silicone tube catheter for the treatment of children`s lacrimal canaliculi rupture.METHODS: A retrospective analysis from January 2014 to December 2015 were taken.According to admission time sequence,42 children with lacrimal canaliculi rupture was divided into two groups.One group was treated with single silicone tube insertion,the other was treated with annular silicone tuber insertion.The treatment results were comparatively analyzed.RESULTS: There were 4 eyes in single silicone tube group occurred fall off in 2wk to 1mo after operations because of improper nursing and the second operations were taken.There was no eye with this in annular silicone tuber groups,the difference between the two groups was significant(P<0.05).In single silicone tube group,16 eyes were cured,1 eye improved,3 eyes unchanged which were the 3 eyes with fall off.Those 3 eyes were 1 patient bitten by dog,2 bombed;the effective rate was 85%.In annular silicone tuber insertion,20 eyes were cured,2 eyes improved and the effective rate was 100%,the difference between the two groups was significant (P<0.05).CONCLUSION: Children`s lacrimal canaliculi rupture should be timely given surgical treatment,reasonable surgical treatment can achieve good operation effect.Annular silicone tube has good stability,fewer complications than single silicone tube,and clinical treatment effect is good.

Several key issues in the diagnosis of osteoporosis were discussed. The definition of osteoporosis and some concepts in bone fracture risk evaluation were explained, so as the methods to avoid the common misunderstandings in clinical practice. Finally, the parameters used in determination of bone metabolism and bone mass were listed, and their application and limitation were analyzed. It may help the clinicians to make correct choice of these parameters.

Objective:To determine PRA and PRB expressions at mRNA and protein levels in endome-trial carcinomas,and to correlate the PRA and PRB expressions in tumours with clinical features inclu-ding grading,surgical stage,degree of myometrial invasion,and lymph node status.Methods:Sixty-sixendometrial carcinomas were investigated with Western blot assays and reverse-transcription polymerasechain reaction.The corresponding clinical information was collected.Spearman's rank correlation wasused to test for association between expressions of total PR and PR isoforms in endometrial carcinomas andclinical features.Results:At protein level,expressions of PRA and PRB were significantly inversely re-lated to grade(r=-0.343,r=-0.310,P

BACKGROUND: The efficacy of Cyclosporin A(CyA) in the treatment of psoriasis is well recongized, the dosage less than 5mg/kg per day(mg/kg/d) is recommended. OBJECTIVE: The purpose of this study is to evaluate the indication, dose, course and side-effects of CyA therapy for psoriasis, especially in China. METHODS: Forty patients with psoriasis were treated with doses of CyA 5mg/kg/d, compared with 20 patients treated with Tigason lmg/kg/d by Global PAST. RESULTS: 1. Of 40 patients 33 patients (82.5%)were cured clinically in 4-5weeks and all the patients(100%) had responses to the therapy. 2. The efficacy and the Global PASI reduction of CyA therapy were significantly better than that of Tigason therapy. 3. During the CyA therapy, no severe side-effects and obvious laboratory changes were found. CONCLUSION: CyA(5mg/kg/d) was satisfactory for psoriasis, especially for psoriasis pustulosa, arthropathica and erythroderma. CyA was found to be superior to Tigason. The therapy course and side-effects seemed to be related to the dosage.

[Objective] To observe the effects of Oysters, Abalone shel , Concha arcae, Mother-of-pearl, Concha cypraeae, Clamshel , these six testacean TCM on the goiter rats. [Method] 72 healthy SD rats were randomly divided into nine groups:normal group, model group, positive group and six testacean TCM groups. Rats were given daily propylthiouracil (0.15 g·kg-1), continuous modeling for 10d, weighing thyroid wet weight,assaying T3, T4 and TSH contents in serum by ELISA, observing the morphological changes of thyroid under light microscope. [Result] Rats in the model group compared with normal group in-creased the relative weight of thyroid, reduced the content of T3,T4, and there was a significant difference( P<0.01), thyroid fol icular epithelial cellhyperplasia was obvious;compared with the model group, Oysters and Clamshel group made the content of T3,T4 in rat rebound, and there was a significant difference (P<0.05);Oyster and Clamshel group’s thyroid fol icular cellhyperplasia were not obvious, while the hyperplasia had different levels for the other 4 kinds of testacean TCM. [Conclusion] Oysters and Clamshel were better to improve the thyroid function of the goiter model rats.

Objective To explore the molecular mechanism of S100A9-induced secretion of vascular endothelial growth factor-A (VEGF-A)by monocytes.Methods Peripheral blood specimen were collected from healthy individuals undergoing physical exami-nation and the CD14 + monocytes were purified by using immunomagnetic beads and the expression of the receptor for advanced gly-cation endproducts (RAGE)was detected by flow cytomertry.In vitro CD14 + monocytes were stimulated by S100A9,and anti-RAGE antibody or NK-κB signal pathway inhibitor were pre-incubated for 1 hour and then stimulated by S100A9,the levels of VEGF-A were detected by using enzyme-linked immunosorbent assay.Results The high level of RAGE was expressed by isolated CD14 + monocytes,after S100A9 stimulation,the secretion of VEGF-A by CD14 + monocytes was significantly increased in a dose and time dependent manner.However,the inducing VEGF-A was significantly decreased(P <0.01 ),while pre-treated with anti-RAGE antibody or NK-κB inhibitor (P <0.01).Conclusion S100A9 inducing the secretion of VEGF-A by monocytes and is de-pended on RAGE-NK-κB signal pathway,suggesting that S100A9 might promote angiogenesis.

The standardized prevalences of CDS suggestiondiagnosed metabolic syndrome(MS) and its components were 11.46% in MS,5.17% in diabetes,16.35% in hypertension,25.59% in high triglyceride level,4.72% in low HDL-C level,18.84% in overweight or obesity in 2512 randomized official employees in Fushan city of Guangdong province in 2003.The MS prevalence was increased with ageing.

Objective To explore the effect of relaxation therapy on rehabilitation patients with functional dyspepsia.Methods 112 cases with functional dyspepsia were randomly divided into test group(n=56) and control group(n=56).Relaxation trains was adopted in test group,usual nursing care was adopted to the patients in both groups.The therapeutic effects and relapse rate were observed in two groups. Results There were no significant differences of clinical curative efficacy in two groups first-visit and less than six-month pathogenesis patients,but compared with the control group,the cure efficacy of recurrent-attack patients and over six-month-pathogenesis patients were significantly lower in test group,and the relapse rate in control group is higher than that in test group. Conclusion The relaxation therapy can promote the rehabilitation in functional dyspepsia patients of recurrent attack and over-six-month pathogenesis,and decrease the relapse rate.

砄bjective:To analyse the effects of age on the color of natural tooth crown. Methods: The color of 1 944 health anterior teeth of 162 chinese people aged 20 to 73 years old was measured with a fiber optic spectrophotometry system. CIE 1976 L *a *b * and CIE 1931XYZ were applied to analyse the color mesurements. Results:The results showed that in three section of teeth(incisor, midlle, cervical) the values of L * and a *were negativly correlated to aging, that of b * was positively just at cervical and midlle sites. The value of b * was not related to age at incisal site of teeth. Conclusion: The values of L * and a * are related to age negatively.

Objective To explore the mechanism of Cryptococcus neoformans mutant in CNLAC1and investigate the difference of CNLAC1between wild type(Mel+ )and the mutant (Mel- ).Methods The ab-normal PCR DNA product of Cryptococcus neoformans was cloned into sequencing vector PG EM-T for se-quencing.An expression vector was c onstructed for efficient expressio n in E.coli DH 5? .The gene was sequenced.Results The cloned DNA sequence was found to b e different between wild type(Mel+)and the mutant (Mel-)(between 1715bp and 2617bp).The differences were not only in len gth,but also in base sequence.Con-clusion The mechanism of the mutant in CNLAC1might be a change of sequence(between 1715bp and 2617bp),and not a DNA deletion.This finding might provide us a target gene for the prognosis and treatment of cryptococcosis.
