Background Many methods are widely studied to improve the therapeutic effect of trabeculectomy for glaucoma,and the clinical effectiveness of the amniotic membrane application during trabeculectomy is one of the research hotspots.Objective This study was to evaluate the efficacy and safety between trabeculectomy with (TE-AMT) and without amniotic membrane transplantation (TE-noAMT) for treating glaucoma.Methods Articles published from 1965 to December 2010 were searched from The Cochrane Library,PubMed,EMBASE,CNKI,Chinese Biomedicine Database,internet by computer,and manual search then was performed according to the predetermined strategy.Randomized controlled trials (RCT) on TE-AMT and TE-noAMT were included.The quality of included articles were scored based on Jadad table,and the relative parameters and information were extracted,including author,design of the trials,country,number of eyes and patients,gender,follow-up duration,age,classification of glaucoma,baseline IOP and loss rate.The main analysis indicators were the percentage of IOP reduction,completely operative successful rate,qualified success rate and adverse events.The pooled estimates were carried out with RevMan version 5.0 software.Results Nineteen RCTs documents were reviewed by meta-analysis with the Jaded scores ≥3 in 2 papers and ＜3 in 17 papers.Total 977 eyes of 818 patients were included.The weighted mean differences (WMD) of the percentage of IOP from baseline were (WMD =8.47％,95％ CI:5.20-11.75) at 6 months and (WMD=9.37％,95％ CI:4.97-13.77) at 12 months postoperatively.Relative risk (RR) of complete success rate and qualified success rate at postoperative 6 months were (1.40,95％ CI:1.19-1.65) and (0.47,95％ CI:0.22-1.00),respectively.RR values of adverse event such as shallow anterior chamber,hyphema,hypotony and choroidal detachment,failed filtering blebs at 6,12 months were 0.51 (95 ％ CI:0.30-0.85),0.43 (95％ CI:0.20-0.92),0.51(95％CI:0.26-1.00) and 0.57(95％CI:0.14-2.31),0.31(95％CI:0.20-0.47),0.31 (95％ CI:0.17-0.55),respectively.Conclusions TE-AMT appears to have better efficacy in lowering IOP,increasing complete success rate and reducing adverse event I in comparison with TE-noAMT.

39℃)developed at the progressive stage of this disease.Physical examination showed variously sized,round or oval,atrophic and variola-like scars along with scattered erythematous patches,papules, necrosis and crusts on the face and extremities.The face was edematous,and there were some edematous and erythematous plaques with a necrotic center on the legs and arms.Histological examination revealed a massive infiltration with atypical CD8~+lymphocytes around the vessels and appendages in dermis.A diagnosis of CD8~+cutaneous T-cell lymphoma(CTCL)was made.Glucocorticoid and immunosuppressants were effective in controlling the condition.Up to the time of the writing,there has not been any definite evidence of systemic involvement.

The purpose of this study is to investigate the enantioselectivity of norgestrel (NG) transdermal permeation and the potential influence of linalool and lipids on the enantioselectivity. In vitro skin permeation studies of NG across the excised rat skins were performed with Valia-Chien diffusion cells, and the permeation samples were analyzed by enantioselective HPLC. The possible enantioselective permeation of NG across intact rat back skin and lipids extracted rat back skin and the influence of linalool were evaluated. The skin permeation rate of dl-NG was two times higher than that of l-NG when donor solutions (EtOH/H2O 2 : 8, v/v) containing l-NG or dl-NG. It may be mainly attributed to the solubility discrepancy between enantiomer and racemate. The enantioselective permeation of dl-NG across intact rat skin was observed when the donor solutions containing dl-linalool. The permeation flux of l-NG was 22% higher than that of d-NG. But interestingly, the enantioselective permeation of dl-NG disappeared under the same experimental condition except that the lipid extracted rat skin was used. Attenuated total reflection-fourier transform infrared spectroscopy analysis of stratum corneum showed that the wave number for asymmetric CH2 stretching vibrations of lipids treated with dl-linalool was greater than that of the control. The results indicated that the enantioselective permeation of NG may be contributed by the interaction between dl-linalool and lipids. More than half of lipids were composed of ceramides. The stereospecific interaction maybe existed among chiral enhancer (linalool), lipids (ceramides) and/or chiral drugs (NG).

ObjectiveTo evaluate the priority application of thin adrenal CT scanning in out-patients with hypertension for early diagnosis of adrenal hypertension.MethodsThe patients with hypertension were collected from January to August 2009,in whom the secondary hypertension ( including endocrine and renal hypertension) and malignant cancers were excluded.All patients accepted the adrenal CT scan firstly,and then the patients with the positive result of morphological abnormalities in the adrenal CT( including adenoma and hyperplasia)were evaluated for endocrine function of adrenal glands.Results A total 362 cases of hypertension were studied,in.cluding 162 males and 200 females.The average age was (60.9 ±9.3 ) year-old,the average duration of hypertension was ( 13.8 ±5.3 ) year.After adrenal thin layer scanner CT scan,35 patients ( 9.6％ ) with adrenal abnormalities were found.Endocrine functional assessments of adrenal glands were carried out among these patients,17 cases (4.7％) with functional lesions were diagnosed,including 14 cases(3.9％ )with primary hyperaldosteronism,2 cases(0.6％ )with Cushing's syndrome,and 1 case ( 0.3％ ) with pheochromocytoma.Conclusion This study revealed that the percentage of adrenal lesions in outpatients with hypertension was 9.6％.The percentage of adrenal hypertension was 4.7％.Thin layer CT scan seems to effectively screen the adrenal hypertension with adrenal lesions,and would be helpful to the diagnosis of endocrine hypertension.

Objective: To investigate the correlation between eukaryotic translation initiation factor 3, subunit A (eIF3a) and human epididymis protein 4 (HE4) expression and ovarian cancer. Methods: RT-PCR or immunohistochemistry was used to examine eIF3a and HE4 mRNA or protein expression in ovarian tissues from patients with ovarian cancer (n=181) or benign ovariantumors, or from the healthy women. Results: hTere were signiifcant differences in mRNA and protein expression of eIF3a and HE4 among normal ovarian tissues, benign ovarian tumor tissues, and ovarian cancer tissues (P<0.05). hTere were signiifcant differences in mRNA expression of eIF3a and HE4 between the normal tissues and the ovarian cancer tissues, or between the benign ovarian tumor tissues and the normal tissues (P<0.001). hTe mRNA expression of eIF3a in the normal ovarian tissues was signiifcantly higher than that in the benign ovarian tumor tissues or that in the ovarian cancer tissues. hTe mRNA expression of HE4 was gradually increased from the normal ovarian tissues, the benign ovarian tumor tissues to the ovarian cancer tissues. hTe mRNA expression of HE4 in the ovarian cancer tissues was signiifcantly higher than that in the benign ovarian tumor tissues (P<0.001). Positive expression rates for eIF3a or HE4 protein in normal, benign tumor, and cancer tissues were 0, 66.7%, and 81.0% or 0, 27.8%, and 56.2%, respectively. hTere were signiifcant differences in positive expression rates of eIF3a protein and HE4 protein between the ovarian tumor tissues and benign ovarian tumor tissues, between the ovarian cancer tissues and the normal ovarian tissues, or between the benign ovarian tumor tissues and the normal ovarian tissues (P<0.001). hTe eIF3a protein expression was positively correlated with HE4 protein expression (r=0.575,P<0.05). Conclusion: The expressions of eIF3a and HE4 are associated with ovarian cancer, and extracellular regulated protein kinases may play a role in the interaction between eIF3a and HE4.
