Motor imagery therapy is based on the theory of plasticity in the central nervous system. Movement with imagery improved reconstruction of damaged motor conduction pathway, and made restoration of central nervous system. Motor imagery adapts to recovery mode of stroke, and was proved to be effective on motor function when applied with physical therapy for stroke patients. This article would review its background, mechanisms, Methods and effects, etc.

Objective To analyze the rented factors leading to successful treatment of ectopic pregnancy by conservative therapy and to explore importance of this therapy. Methods 152 patients with ectopic pregnancy performed with conservative treatment were randomly recruited into a methotrexate plus Chinese medicine group, a 5-fluorouracil plus Chinese medicine group and a exclusive Chinese medicine group. The curative rate and side effect were observed in groups, and the relation between the treatment condition and the curative rate was analyzed. Results There was no difference in curative rate among groups, while the side effect in the exclusive Chinese medicine group was lower than other groups. It showed high curative rate in patients with two or more conditions of having mass less than 3 cm, the level of bloodβ-hCG less than 1000 IU/L, and the depth of posterior fomix effusion less than 1 cm. Conclusion Among the treatments of ectopic pregnancy, Chinese medicine has fewer side effects. Fully evaluation on the treatment condition can improve the curative rate.

Objective To investigate the effects of angiotensin Ⅱ AT1 receptor antagonist-Candesartan on production of leptin, adiponectin and TNF-? in rat. Methods 20 male Wistar Kyoto rats were randomly divided into vehicle and Candesartan treated groups. The dosage of Candesartan was 10mg?kg~ -1 ?d~ -1 . Food intake and bodyweight were recorded each week. Rats were sacrificed by decapitation after 17 weeks. Epididymal and perirenal fat were collected and weighted. Adipocytes were isolated from epididymal adipose tissue with collagenase. Diameter of adipocyte was evaluated. Blood chemistry, insulin, leptin, adiponectin and TNF-? were assayed. mRNA expressions of leptin, adiponectin and TNF-? of epididymal adipose tissue were assayed with RT-PCR. Results In Candesartan treated group, bodyweight and content of adipose tissue were significantly decreased, and adipocytes shrunk. Blood glucose and insulin levels showed no difference between two groups. Plasma leptin level and leptin mRNA expression in adipose tissue were lower, and plasma adiponectin level as well as adiponectin mRNA expression were higher in Candesartan treated group. Plasma TNF-? level was too low to detect with super sensitive kit, and mRNA expression of TNF? was decreased in Candesartan treated group. Conclusions Angiotensin Ⅱ AT1 receptor antagonist decreases the production of leptin and TNF-?, enhances synthesis as well as release of adiponectin in rat adipose tissue.

A retrospective study of endocrine dysfunction in 65 patients with Rathke's cleft cyst (RCC) was conducted. Before surgical operation, most patients with RCC had various degrees of pituitary dysfunction.Impaired gonadotropin secretion and prolactinemia were the prevalent abnormalities. Erectile dysfunction or diminished libido in male and menstrual disorder or galactorrhea in female were frequently seen. The panhypopituitarism appeared in a few patients with RCC. The patients would benefit by surgical removal, however,attention should be paid to avoid new damage of the pituitary gland during operation.

Objective To analyze the clinical characteristics of large pulmonary vessel involvement in Behcet's diseaseMethods The clinical data of Behcet's disease patients with large pulmonary vessel involvement,who were treated in Peking Union Medical College Hospital from 1983 to 2008,were retrospectively analyzed.Results Thirteen patients had large pulmonary vessel involvement among a total of 418 patients with Behcet's disease.The 13 patients had a mean age of (37.5?12)years old,with 10(69.2%)having hemoptysis,8(61.5%)having dyspnea.Helical CT/CTPA showed that pulmonary vascular involvement included pulmonary arterial aneurysms(53.8%),pulmonary artery occlusion(46.2%),and pulmonary thrombi(46.2%).All the 13 patients were treated with steroid and immunosuppressant;five received steroid pulse therapy;and four received vascular intervention therapy.The mean follow-up was (3?1.6)years,with a follow-up rate of 92.5%.The 3-year survival rate was 83.9% for the 13 patients.Conclusion The manifestation of pulmonary vascular involvement in Behcet's disease is various,and the diagnosis mainly depends on the manifestations of CT pulmonary angiography.

Objective To observe the effect of Astragalus injection on the expressions of inflammatory cytokines in human primary macrophages stimulated by lipoteichoic acid (LTA) and lipopolysaccharide (LPS),and investigate its effects on inflammatory reactions of Gram-positive (G+) and Gram-negative (G-) bacteria sepsis and its mechanisms.Methods Percoll density gradient centrifugation was used to isolate the human peripheral blood mononuclear cells,then they were purified by immune Anti-Biotin Microbeads with magnetic character and under the induction of recombinant human granulocyte-macrophage colony stimulating factor (rhGM-CSF),the cells were cultivated for 12 days in vitro,eventually the human monocyte-derived macrophage was formed.The cultured human macrophages were inoculated in 96-well plates (each group 3 wells) and 6-well plates (each group 3 wells).The cells were divided into control group (200 μL DMEM added in each well),LTA 1 mg/L group,LPS 0.1 mg/L group and low astragalus injection (0.1 mg/L) and high astragalus injection (0.2 mg/L) dose groups.After the incubator plates were put in an incubator for 24 hours,the protein content of IL-8 and IL-10 in supernatant were detected by enzymelinked immunosorbent assay (ELISA),and the mRNA expression levels of IL-8 and IL-10 were detected by real time fluorescence quantitative reverse transcription-polymerase chain reaction (RT-qPCR).Results LTA and LPS all can obviously up-regulate the expression levels of pro-inflammatory factor IL-8 and anti-inflammatory factor IL-10 of macrophage.The expressions of IL-8 and IL-10 protein and mRNA in LTA group and LPS group were significantly higher than those in control group after cuhure for 8 hours and 24 hours,the degrees of increment were more significantly at 24 hours [LTA stimute group:IL-8 protein (ng/L,× 103):41.57± 1.90 vs.1.58 ±0.24,IL-8 mRNA (A value):21.49±8.05 vs.1.00±0.16;IL-10 protein (ng/L):5.90±3.02 vs.2.91 ± 1.54,IL-10 mRNA (A value):1.35±0.34 vs.0.95±0.14;LPS stimute group:IL-8 protein (ng/L,× 103):345.00±22.80 vs.5.60±0.31,IL-8 mRNA (A value):29.84 ± 8.93 vs.1.00 ± 0.16,IL-10 protein (ng/L):122.37 ± 39.26 vs.44.79 ± 3.67,IL-10 mRNA (A value):7.38 ± 1.58 vs.1.35 ± 0.34,all P ＜ 0.05].The Astragalus injection could regulate LTA and LPS to stimulate the macrophage to decrease the expression levels of pro-inflammatory factor IL-8 protein and mRNA and increase the expression levels of anti-inflammatory factor IL-10 protein and mRNA in the macrophage;the changes of regulatory effect in the 24 hour-culture of Astragalus injection high dose group was the most significant [LTA stimute group:IL-8 protein (ng/L,×103):22.63±1.91 vs.41.57±1.90,IL-8 mRNA (A value):12.10±1.93 vs.21.49±8.05,IL-10 protein (ng/L):14.03±2.22 vs.5.90±3.02,IL-10 mRNA (A value):10.37±6.08 vs.1.35±0.34;LPS stimute group:IL-8 protein (ng/L,× 103):167.75 ± 19.90 vs.345.01 ±22.80,IL-8 mRNA (A value):15.61 ± 3.63 vs.29.84±8.93;IL-10 protein (ng/L):243.22±14.41 vs.122.37±39.26,IL-10 mRNA (A value):16.14±4.10 vs.7.38± 1.58,all P ＜ 0.05].Conclusions In the process of inflammatory response,the pro-inflammatory and anti-inflammatory factors co-exist simultaneously.Astragalus injection can inhibit the expression levels of pro-inflammatory factor gene and protein in the inflammatory response of G+ and G-bacteria sepsis and in the mean time,it can promote the expression levels of anti-inflammatory factor gene and protein,thus the immune mechanism of sepsis is affected,achieving the balance between pro-inflammation and anti-inflammation.

AIM:To evaluate the availability and our experience of intraoperative image-guidance in endoscopic nasocular operation.METHODS:Seven cases of endoscopic nasal surgery with intraoperative image-guidance were retropectively reviewed,including 3 cases of optic nerve injury;3 cases of foreign object of optic behind the eyeball;1 case of retrobulbar tumor(angeioma).RESULTS:The preoperative preparatory time would take 15 minutes,including coordination,head holder localization,conventional instrument registration.In our cases,the localization accuracy between 3-D image landmarks of navigation system and actual anatomical landmarks was less than 1.3mm.The optic nerve and other anatomical points could be orientated accurately in intraoperative procedures.No complication occurred.CONCLUSION:Nasal endoscope combined with imageguidance systems provides accurate anatomical localization of anterior skull base with enlarged operation field.It is possible for surgeons to observe important anatomical structures during endoscopic surgery.It could increase the effectiveness and decrease surgical complications,especially in complicated cases.

Objective To establish the nonalcoholic fatty liver disease(NAFLD) model in SD rats and to investigate if endoplasmic reticulum stress(ERS) plays a role in the pathogenesis of NAFLD. Methods A total of 36 male SD rats were randomly divided into 4 groups: normal control group 1(N1,n=8), normal control group 2 (N2,n=8), model group 1(M1,n=10) and model group 2(M2,n=10). The two control groups were fed with normal diets, whereas the two model groups were provided diets enriched in fat (10% lard oil and 2% cholesterol). The rats in N1 and M1 groups were sacrificed at the 12th week, and those in N2 and M2 groups were sacrificed at the 20th week. The serum alanine aminotransferase (ALT), aspartate aminotransferase(AST), alkaline phosphatase (ALP), total protein (TP), triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL) were measured. The steatosis, immflamation and fibrosis of the liver were observed with HE and Masson staining. The expressions of GRP78, CHOP and procaspase-12 mRNA were tested using real-time PCR and the activation of procaspase-12 protein was detected by Western blot. Results At the 12th week, the liver index and the serum levels of ALT, AST,ALP,TP,TC,LDL in M1 group were significantly higher than those in N1 group (P<0.01), but HDL level was significantly lower in M1 group than that in N1 group (P<0.01). At the 20th week, the concentrations of TC and LDL in M2 group were significantly increased in comparison with N2 group. The histochemical study revealed that the hepatic steatosis and inflammation in M1 and M2 groups were more serious than those in N1 and N2 goups(P<0.01). The slight fibrosis was seen in M2 group. At the 12th and 20th weeks, the expressions of GRP78,CHOP and procaspase-12 mRNA and protein in M1 and M2 groups did not differ in N1 and N2 groups. Conclusions The fat-rich diet might successfully induce NAFLD in rats and there is no ERS observed in the study, which suggests that ERS may not be involved in the pathogenesis of NAFLD.
