Objective To investigate the clinical effect of Gonadotropin-releasing hormone agonist (GnRHa) combined with addback therapy after laparoscopic surgery on 153 cases with severe endometriosis patients. Methods 153 cases with severe endometriosis patients who underwent laparoscopic surgery from 2011 to 2013 were retrospectively analyzed in the Second Affiliated Hospital of Zhengzhou University. According to GnRHa or addback therapy three groups were divided:GnRHa group,GnRHa and addback therapy group, control group. The curative effects of different treatment group, adverse reactions, recurrence rates, and fertility were analyzed. The follow-up time was 6-24 months with an average time of 17.15 months. Results 51 patients suffered from obvious menopausal symptoms and received addback therapy (Progynova,0.5~1 mg/d). The VAS score and Kupperman score in GnRHa group,GnRHa and addback therapy group were significantly superior to the control group (P <0.05). And no statistical significance was found in the interval to relapse, recurrence and postoperative pregnancy rate (P>0.05). The VAS scores in the GnRHa group and addback therapy group were 2.14±2.02 and 1.73±2.17 , respectively (P > 0.05). The main side effect of GnRHa group is hot flashes, diaphores, insomnia, sexual dysfunction, etc. The incidences were higher in the GnRHa group than that in the addback therapy group. But the addback therapy can significantly relieve the symptoms of low estrogen introduced by the application of GnRHa (P<0.05). Conclusions Laparoscopic combined with GnRHa treatment can significantly improve clinical curative effect of endometriosis. Addback therapy could abate the side reaction of GnRHa and do not affect the clinical curative effect. The clinical curative effect in the GnRHa and addbacktherapy group were superior to the GnRHa group.

ObjectiveTo explore the clinical features,etiological factors,diagnosis and treatments in children with hemophagocytic syndromes (HPS).MethodsA retrospective study was carried out to analyze etiological factors,clinical symptoms and sighs,laboratory findings and outcomes of 32 children with HPS in our hospital.Results( 1 ) Etiological factors:virus infection cases accounted for 75.0％ (24/32),in which Epstein-Barr virus infection cases were predominant,making up to 68.8％ (22/32) ; (2) Main clinical features:included persistent fever,hepatosplenomegaly,lymphadenopathy; ( 3 ) Characteristic laboratory findings:included decrease of three lines or two lines of peripheral blood cells,hyperferrttinemia,abnormal liver function and coagulation function,hypertriglycerdema and decreased fibrinogen,hemophagocytosis in bone marrow,high soluble interleukin-2 receptor level,decreased natural killer cell activity.(4) Treatments and outcomes:twenty-four(24/32) virus infection cases received antivirus and high dose of immunoglobulin treatment.Twenty-two cases were treated with glucocorticoid and cyclophosphamide,resulting in 11 cases improvement,5 cases with complete remission,2 cases giving up and 4 death.The other 10 cases were treated under the guide of HLH-2004 protocol treatmemt with 4 cases improved and 6 cases with complete remission.Conclusion HPS is mainly triggered by infections,especially Epstein-Barr virus infection.Serum ferrifin,interleukin-2 receptor level and natural killer cell activity are biomarkers of the disease,so that they should be monitored during the progress of chemotherapy.HLH-2004 protocol is a good guide for the treatment of this disease.

Epidemiologic studies suggest that intake of excess all-trans-retinoic acid (RA) during embryogenesis induces various developmental defects and the central nervous system (CNS) represents a major site of the teratogenic action of RA. It is therefore important to understand which parameters are affected early by excessive RA in order to devise and improve protective nutritional strategies. The modulations of beta-catenin and caspase-3 levels were investigated in the KM mouse embryo following maternal treatment with a single oral dose of 30mg/kg body weight of RA during the neurula period. In addition, retinoic receptors (RARs) are key transcription factors regulating gene expression in response to RA-activated signals. So the experiment was designed to evaluate whether the alterations in protein expression of RAR alpha and beta during the time of neural tube closure were induced by excessive RA. Maternal intake of excess RA induced early downregulation of RAR alpha and beta, beta-catenin and caspase-3 expression, which was followed by an increase in their expressive levels in the neural tube tissue of mouse embryos. This finding suggests that the alterations in the expression profile of RAR alpha and beta, beta-catenin and caspase-3 may be implicated in the teratogenesis induced by excess RA in KM mouse embryo.
