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.

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 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.

Objective This experiment was designed to determine the effect of haloperidol on HSP70 induced by ketamine, and to explore the possibility of using haloperidol to prevent or treat the brain injury caused by ketamine.Methods 48 rats were divided into 8 groups, In group 1-3 different doses of haloperidol (1.0,5.0,10.0 mg/kg)were given 1h before the administration of ketamine. There were two control groups. In control group 1 normal saline was given twice with 1h interval between the two injections. In control group 2 ketamine 80.0 mg/kg was given 1h after the administration of normal saline.The volume of each injection was 3ml and intraabdominal injection was used as the route of administration.HSP70 mono-clone antibody immunocytochemistry was used to detect HSP70 expression in rat hippocampus, and MIAS-2000 photography analytic software to analyze HSP70 expression in hippocampus of the rat brain.Results Ketamine induced HSP70 expression in the rat brain. Pretreatment with haloperidol inhibited HSP70 expression induced by ketamine, and the inhibition was dose-dependent, but haloperidol given after the administration of ketamine could not decrease HSP70 expression.Conclusions Ketamine injures neurons of rat hippocampus and induces the expression of HSP70 and haloperidol pretreatment can prevent neuronal injury caused by ketamine, but haloperidol can not antagonize the injury caused by ketamine.

Objective To evaluate the myocardial protection afforded by ketamine midazolam in its septic shock and its possible mechanism by studying the impact of ketamine midazolam on myocardial HSP 70 expression in LPS induced septic shock in rats Methods 112 healthy adults SD rats of both sexes, weighing 180 205g were randomly assigned to one of following groups:(Ⅰ)control group received normal saline ip (group NS); (Ⅱ) endotoxin group received LPS 20mg?kg -1 ip(group E); (Ⅲ) endotoxin midazolam group received midazolam 0 5mg?kg -1 20 min before LPS (group EM); (Ⅳ) endotoxin ketamine group received ketmine 80mg?kg -1 20 min before LPS (group EK); endotoxin ketamine midazolam group received ketmine 80mg?kg 1 and midazolam 0 5mg?kg -1 20 min before LPS (group EKM) One hour later half of the initial dose of ketamine and/or midazolam was given to reinforce their effect Heart was harvested 2h after LPS or when the rats died of LPS induced septic shock(pupil did not respond to light) for determination of HSP 70 expression using monoclone antibody immunocytochemistry The survival time of every rat was recorded Results The expression HSP 70 was higher in group E than that in group NS and was lower than that in group EK and EKM The survival rate of group EK and EKM was higher than that of group E and EM (P0 05) Conclusions Ketamine can enhance myocardial HSP 70 expression in septic shock This may be one of the mechanisms of its myocardial protection Joint use of ketamine midazolam dose not affect the myocardial protective effect of ketamine

Objective Investigation of the effect of integrin on fibroblasts from scleroderma in the production of procollagen. Methods Phosphorothioate modified antisense oligonucleotides were used to interfere with the expression of integrin ? 5 or ? 1 subunit on scleroderma fibroblasts respectively, then the changes of procollagen mRNA were detected by RT PCR. Results The expression of integrin ? 5 or ? 1 subunit could be specifically inhibited by their antisense oligonucleotides respectively. Decreased expression of fibroblast integrin ? 5 or ? 1 subunit significantly lowered mRNA of procollagen ? 1(Ⅰ) and ? 1(Ⅲ). Conclusion Overproduction of procollagen may be inhibited in the level of transcription by lowering the expression of integrin on fibroblasts in scleroderma.
