Objective To investigate the effect of progesterone pretreatment of focal cerebral ischemic and reperfusion injury (fCIRI) and underlying molecular mechanisms.Methods A single intraperitoneal injection of progesterone (8 mg/kg) given 1 h,48 h and 96 h before fCIRI was established in male Sprague-Dawley rats.The number of survival of neurons in hippocampal CA1 region of the ischemiaside,as well as spatial memory function,was detected on days 3-8 after fCIRI.Extracellular-signalregulated kinase 1/2 phosphorylation (p-ERK1/2) and nuclear translocation of p-ERK1/2 in hippocampal CA1 region were examined using western blot.Results The number of survival of neuronal cells was significantly increased in ischemic groups treated with progesterone at 1 h and 48 h pre-fCIRI (164.3 ± 11.0,218.5 ± 9.1 and 142.7 ± 12.1,F =29.4,P ＜ 0.01) compared with fCIRI group treated with vehicle.Likewise,the escape-latency to reach the hidden-platform recorded in day 5 of Morris water maze test was reduced markedly in fCIRI-treatment groups compared with the vehicle group(10.3 ± 11.1,19.2 ±9.6 and 32.4 ± 14.3 ;F =35.8,P ＜0.01).The level of p-ERK1/2 was elevated notably during 24 h to 48 h postprogesterone by western blot,while restored to the baseline at 96 h post-progesterone.Improved nuclear translocation of p-ERK1/2 was observed from 2 h to 48 h post-progesterone.The progesterone receptor antagonist RU486 blocked the exaltation of either intracellular level or nuclear translocation of p-ERK1/2,which was induced by progesterone.Conclusions The pretreatment with progesterone exerts a neuroprotective effect against the ischemia-induced neuronal death and ameliorates the deficits in spatial memory through enhancing the activation of ERK1/2.The neuroprotection derived from pretreatment with progesterone achieves a time window of not less than 48 h,which is progesterone receptor-mediated ERK1/2 signaling pathway-dependent.

Objective To study the association of tryptophan hydroxylase-2 (TPH2) gene polymorphism and antisocial personality disorder (ASPD) and its impulsivity in Chinese Han population. Methods The single nucleotide polymorphism (SNPs) of TPH2 in transcriptional control region,-703G/T,was analyzed by PCR-RFLP genotyping assay in 117 ASPD patients and 142 healthy controls. Barratt Impulsiveness Scale-11 (BIS-11) was used to evaluate the impulsivity of subjects. Results There were significant differences between ASPD and controis on genotype and allele frequencies of TPH2-703G/T (x2 = 7.73, P ＜ 0.05; x2 = 5.12, P ＜ 0.05). The GG genotype and G allele were positively associated with ASPD(OR = 1.458,95% CI = 1.080 ～ 1.968 ;OR = 1.479,95% CI = 1.045 ～ 2.094). The scores of BIS-11 and its factors in GG genotype group((71.28 ± 7.50), (19.60 ±3.41), (25.73 ± 4.92), (25.95 ± 4.77) ) were higher than GT genotype group (( 66.23 ± 8.06), (17.79 ±3.02) ,(23.06 ±3.84) ,(25.38 ±4.97)) and TT genotype group((66.55 ±8.49),(18.50 ±3.35),(23.45 ±4.08), (24.97 ± 4.90)), but only the difference of BIS-11 total scores, the attention and motor factor scores among three groups were statistically significant (P＜0.05). The scores of BIS-11 and its factors in G allele group ((69.38 ±8.04), (18.92 ± 3.36), (24.73 ±4. 69), (25.73 ±4.82)) were higher than T genotype group ((66.41 ±8.22),(17.98 ±3.26),(23.27 ±3.94), (25.15 ±4.89)),however,only the difference of BIS-11 total scores, the attention and motor factor scores between two groups were statistically significant.Conclusion TPH2-703G/T polymorphism may be association with ASPD in Chinese Han population. The GG genotype and G allele may be the risk factors of ASPD and impulsivity.

Objective To observe the control effect of heat preservation infusion on incidence of infection after artificial abortion.Methods 168 cases of patients after artificial abortion were randomly divided into the heat preservation infusion group and normal infusion group with 84 cases in each group.The normal infusion group received routine nursing,and was intravenously infused fluid with non heat preservation method,the heat preservation infusion group was intravenously infused constant temperature liquid heated to 37℃.The incidence of infection was observed in two groups of patients after artificial abortion.Results The infection rate of the heat preservation group was significantly less than the normal infusion group.Conclusions Heat preservation infusion can effectively reduce the infection rate after artificial abortion.

Objective To investigate the application effect of evidence-based nursing(EBN) in family planning surgery,evaluate the clinical nursing value and improve the quality of clinical nursing.Methods 240 patients who received family planning surgery were randomly divided into the control and the observation groups (120 patients in each group).The conventional nursing model was used in the control group and evidence-based nursing was implemented in the observation group.Self-rating Anxiety Scale(SAS),patients satisfaction(PA) and adverse reaction rate(ARR) were adopted to assess the two groups after different nursing.Results The score of SAS and ARR were significantly lower in the observation group than those in the control group.The patients satisfaction was significantly higher in the observation group than the control group.Conclusions Application of evidence-based nursing plays a significant role in treatment,nursing and life quality improvement of patients with family planning surgery,which is worthy of wide application.

Objective To explore the constant temperature infusion on postoperative body temperature and blood coagulation of patients undergoing induced labor.Methods Eighty patients undergoing induced labor were divided into the observation group and the control group randomly:In the former the infusion was done using fluids constantly kept at the temperature of 36℃and in the latter,the infused fluid was kept at room temperature.The two groups were compared in terms of changes of body temperatures,loss of energy,postoperative blood loss and blood coagulation.Results The temperatures of the controls were declined to different extents after infusion and the temperatures of the observation group showed no significant change,but the difference between the two groups was significant(P<0.05).As for the blood coagulation,there were no significant differences in the prothrombin time(PT),activated partial thromboplastin time(APTT)and thrombin time(TT)between the two groups(P>0.05),but the platelet(PLT)and fibrinogen(FIB) content were significantly decreased(P<0.05)and the blood loss of the observation group was significantly less than those in the control group(P<0.05).Conclusion The constant temperature infusion may maintain the temperature and blood coagulation of the patients, reduce blood loss and prevent adverse reactions induced by induced labor.

Objective:To study deeply on the effects of sinomenine on Th1 type cytokines expression of T lymphocytes.Methods:The authors isolated and cultured the mesenteric lymph nodes of mice in vitro.The lymphocytes were stimulated with PDB and inomycin after added sinomenine in different concentrations for 1 hour.After 4 hours stimulation,cells were collected and stained intracellular cytokines with the dying regents,then the expression of Th1 type cytokine IFN-?,pro-inflammatory cytokine TNF-? of T lymphocytes were analyzed by flow cytometry.And also observed the effects of drugs on the expression of CD69,an early marker of T cell activation.Results:1 000 ?mol/L(329.4 ?g/ml)sinomenine can downregulate CD69 expression of T lymphocytes while 200 ?mol/L sinomenie show no effect on it.200,1 000,2 000 ?mol/L sinomenine can obviously reduce the expression of intracellular cytokines such as IFN-?,TNF-? in dose-dependent manner.Conclusion:One of the immunological mechanisms of sinomenine to treat rheumatoid arthritis may due to the inhibitory effects on abnormal T lymphoctytes activation.The inhibitory effects of sinomenine may mainly be relative to the inhibitory effects on Ca 2+ -dependant signal pathway of T lymphocytes activation but not PKC pathway.

IgG 4 related disease (IgG 4-RD) is an immune medicated rare disease, characterized with chronic inflammation and fibrosis in the involved organs, it is a systemic disease affected nearly every anatomic site of the body, usually involvement of multiple organs, and with diverse clinical manifestations. Due to the the relative novelty of the disease and under-recognition, the overall level of diagnosis and treatment in China is uneven. Till now, there is no relevant expert consensus or guidance of IgG 4-RD in China. In order to further improve the understanding and standardize the management of IgG 4-RD, on the basis of summarizing domestic and international experience, the China Alliance For Rare Diseases, together with the Chinese Rheumatology Association, organized an expert group and established the Chinese expert consensus on the diagnosis and treatment of IgG 4 related diseases.
