Drug addiction is a chronic relapsing brain disease. Repeated drug exposure can cause neuroadaptations in major brain circuitries,leading to compulsive drug consumption behav-ior and relapse after abstinence.Many studies have found that intercellular signaling cascades mediated central nervous system remodeling in the rewarding circuitry and addiction associated neuroplasticity of learning and memory are important molecular mechanism of drug addiction.Studies show that extracellular sig-nal-regulated kinase (ERK)is associated with drug-mediated psychomotor activity,rewarding properties and relapse of drug seeking behaviors.Therefore,this article has reviewed the role of ERK signaling pathway in drug addiction.Research on the role of ERK signaling pathway in drug addiction will provide im-portant theoretical foundation for in-depth understanding of the molecular mechanism of drug addiction and shine a light on new molecular targets and treatment strategies for drug addiction.

Drug addiction is a chronic relapsing brain disease that is characterized by compulsive drug use and persistence of drug craving. Drug abuse can lead to changes in the neuron structure and function of plasticity,alterations in molecules and cells,and ultimately to individual abnormal behavior. Current studies have found that epigenetic changes leading to the sustainability of gene expression is an important mechanism of drug addiction. In this review,we will systematically summarize the latest advances in epigenetic mechanisms of drug addiction. This review is expected to provide robust evidence that repeated exposure to drugs of abuse induces changes within the brain′s reward regions in three major modes of epigenetic regulation-histone modifications such as acetylation and methylation , DNA methylation,and non-coding RNAs. It promises a new perspective from which to gain insights into the genetic and epigenetic mechanisms of drug addiction and a new area for epigenetic research on clinical drug addiction treatment.

BACKGROUND:The form and structure of antigen-extracted xenogeneic cancel ous bone through series of physical and chemical treatment are similar to human tissue. OBJECTIVE:To detect the biocompatibility of antigen-extracted xenogeneic cancel ous bone matrix prepared by three different ways. METHODS:The antigen-extracted xenogeneic cancel ous bone scaffold materials which were prepared through physical, chemical and physical-chemical combined methods and hydroxy apatite biological ceramic materials were implanted into the dorsum subcutaneous tissue. Histological observation was done at 4, 8 and 12 weeks after surgery. The antigen-extracted xenogeneic cancel ous bone scaffold materials which were prepared through physical, chemical and physical-chemical combined methods respectively was used to culture sheep bone marrow mesenchymal stem cells for 7 days. Cel adhesion, growth, proliferation and stroma secretion were observed. RESULTS AND CONCLUSION:At 4 weeks after surgery, a strong inflammatory reaction was detected around materials in four groups. At 12 weeks, the xenogeneic bone materials prepared through physical and physical-chemical combined methods and hydroxy apatite biological ceramic materials internal pore and surrounding tissue inflammation disappeared basical y, with the presence of thimbleful inflammation cells. The material degradation was more than at 8 weeks. The xenogeneic bone materials prepared through chemical methods material internal pore and surrounding tissue inflammation stil existed, suggesting that the xenogeneic bone materials prepared through physical and physical-chemical combined methods exhibited good histocompatibility. A smal amount of orderly osteoblasts existed around hydroxy apatite biological ceramic materials and physical-chemical prepared materials, with a smal amount of bone. These suggested that there was a tendency for ectopic bone formation. The xenogeneic cancel ous bone materials prepared through physical or physical-chemical combined methods have better cytocompatibility. However, scaffold materials prepared through chemical method have poor cytocompatibility and they are not qualified for the safety standards of biological materials.

Objective To investigate the effect of double lumen tube applied in the simple negative pressure drainage.Methods Forty cases were divided into two groups by a random table method,with 20 cases in each group. The double lumen tube was used in observation group while the normal gastric tube was used in control group,then the indexes on the drainage effect and wound healing were quantized and analyzed.Results In the observation group,one case suffered obstruction at 2 -4 days,1 case after 4 days of treatment,the obstruction rate was 10%.In the control group,two cases suffered obstruction at 2 -4 days,and 2 cases after 4 days of treatment,the obstruction rate was 25%.There was significant difference between two groups(χ2 =9.212,5.021,P =0.027,0.032).There were two cases of delayed healing and 17 cases with effective in the observation group,but 8 cases delayed healing and 11 cases with effective in the control group,there was statistically significant difference (χ2 =5.833,4.800,P =0.016, 0.028).Conclusion Double lumen tube can delay the occurrence time and reduce the occurrence rate of obstruction in simple negative pressure drainage,which promotes wound healing,and it is worth popularizing and using clinically.

OBJECTIVE:To investigate the effects of Qigong pills decoction combined with chemical drugs on hormone levels of polycystic ovarian syndrome(PCOS)patients complicated with infertility. METHODS:A total of 98 PCOS patients complicated with infertility selected from gynaecology department of our hospital during Jul. 2015-Jun. 2016 were divided into observation group and control group according to random number table,with 49 cases in each group. Control group was given Clomiphene ci-trate tablet 50 mg orally,qd,for consecutive 5 d;B-ultrasonography for follicle development was monitored at the 11th day of menstruation,and then they were given Chorionic Gonadotropin for injection 2000 U intramuscularly,qod,if there was not domi-nant follicle >10 mm till the diameter of follicle reached 18 mm. Observation group was additionally given one dose of Qigong pills decoction,every day 400 mL after decocted with water,each 200 mL for morning and night,on the basis of control group. After 3 months of treatment,the levels of FSH,LH,PRL,E2,T,DHEA-S and SHBG,the endometrial thickness,the number of mature follicle and pregnancy rate were compared between 2 groups. RESULTS:Before treatment,there was no statistical signifi-cance in the levels of FSH,LH,PRL,E2,T,DHEA-S or SHBG between 2 groups(P>0.05). 3 months after treatment,the lev-els of PRL,T and DHEA-S in 2 groups were decreased and E2,SHBG were increased significantly;the levels of FSH,PRL,T and DHEA-S in observation group were significantly lower than control group,while the levels of E2 and SHBG were significantly higher than control group,with statistical significance (P<0.05). Endometrial thickness of observation group were significantly higher than that of control group;pregnancy rate (18.37%) was significantly higher than control group (4.08%),with statistical significance (P<0.05). CONCLUSIONS:Qigong pills decoction combined with chemical drugs can help to improve pregnancy rate and regulate serum hormone level in the treatment of PCOS complicated with infertility.
