ObjectiveTo observe the effect of raloxifen, a selective eastrogen receptor modulator, on postmenopausal osteoporosis.MethodsSixty six patients with postmenopausal osteoporosis were randomly divided into test group and control group with 33 cases in each group. Patients in the test group were treated with raloxifen (60 mg/day) for six months, at same time; cases in the control group were treated with placebo. Before and after treatment,routine laboratory examinations, transvaginal B type ultrasonic examination, and diagnostic curettage were performed. ResultsThe bone mineral densities of lumbar vertebrae and hip were significantly higher in the test group(60.6%) than in the control group(21.2%) (P<0.01). ConclusionRaloxifen is an effective medicine to treat postmenopausal osteoporosis, and it is also safe, without side effect of stimulating endometrim, etc.

Objective To investigate the role of serum and glucocorticoid regulated protein kinase (SGK) 1 in the inflammatory responses mediated by toll like receptors.Methods Mice were injected with lipopolysaccharide (LPS,1 mg/kg) 2 h after the pretreatment of EMD638683 (10 mg/kg) or phosphate buffered saline (PBS) as control.At the time points of 3 and 24 h,pro-inflammatory cytokines (interleukin [IL]-6,IL-12 and tumor necrosis factor [TNF]-α) in serum were measured using enzymelinked immunosorbent assay (ELISA).Livers and lung were harvested at 6 h and 24 h after the injection of LPS,embedded by optimum cutting temperature (OCT) and then stained with hematoxylin and eosin (HE).Peripheral blood mononuelear cell (PBMC) were isolated and stimulated by LPS with or without the pretreatment of EMD or LY294002.Cytokines (IL-6,IL-12 and TNF-α) were measured using ELISA.IKKα/β,IKBα and nuclear factor (NF)-κB p65 were detected by Western bolt.Data were analyzed by one way analysis of variance.Results In the model of LPS-induced endotoxin sepsis,inhibition of SGK1 induced secretion of pro-inflammatory cytokine (IL-6 [t=3.007,P＜0.05],IL-12[t=4.413,P＜0.05] and TNF-α[t=5.403,P＜0.05]),increased inflammatory cells infikration into the liver and lung within 6 h,and induced serious multiple organ damage with collapse of alveoli and fatty degeneration of liver.After 24 h,pharmacological inhibition of SGK1 with EMD638683 increased proinflammatory cytokine (IL-6 [t=18.540,P＜0.01],IL-12[t=16.520,P＜0.01] and TNF-α[t=34.880,P＜0.01]) production in human PBMC upon LPS stimulation and inhibited the phosphorylation of IKKα/ β/IKBα and nuclear factor (NF)-κB p65.Conclusions SGK1 suppresses the toll like receptor 4 mediated inflammatory responses via NF-κB.

Objective To detect the changes of hemodynamics in patients with portal vein embolization (PVE) before surgery for hilar cholangiocarcinoma, and analyze the relationship between hemodynamics and liver hypertrophy. Methods The clinical data of 21 patients with hilar cholangiocarcinoma who were admitted to the Eastern Hepatobiliary Surgery Hospital from April 2008 to December 2009 were retrospectively analyzed.Relevant hemodynamic variables were detected and analyzed before and 3, 7, 14 days after PVE. Data were processed using Student t test or linear correlation analysis. Results The main portal vein pressure after PVE was (25.9 ± 4.1 ) cm H2O ( 1 cm H2O = 0.098 kPa), which was ( 3.5 ± 2.5 ) cm H2O higher than that before PVE [( 22.4 ± 4.1 ) cm H2O] ( t = - 6. 504, P ＜ 0.05 ). The blood flow velocity in the non-embolized branch of portal vein increased after PVE, and reached peak [(26 ±9)cm/s] at the seventh day after PVE. A positive correlation was found between the hypertrophic rate of the non-embolized lobes and the ratio of embolized lobes to total liver volume ( r = 0. 593, P ＜ 0. 05 ). Conclusion Greater scope of the embolized vascular bed of portal vein induces higher hypertrophic rate of non-embolized liver.

Objective To observe the changes of respiratory and hemodynamic functions in children with different age undergoing laparoscopic Nissen's fundoplication(LNF). Methods Thirty-three children with LNF were divided into three groups according to the age: group Ⅰ,1 to 12 months,n=13;group Ⅱ,1 to 3 years old,n=10;and group Ⅲ,4 to 7 years,n=10.Heart rate(HR),mean arterial pressure,Ppeak,compliance of the respiratory system(CRS) and end-tidal carbon dioxide pressure(PETCO2) were recorded 5 min before pneumoperitoneum(T0),10 min(T1),60 min(T2) after pneumoperitoneum and 10 min after deflation(T3),and parameters of blood gas analysis such as PaCO2 were measured at the same time. Results Compared with those at T0,HR,Ppeak,PETCO2 and the difference between PaCO2 and PETCO2(Pa-ETCO2)were significantly increased at T1 and T2,while CRS was significantly decreased.The most significant changes were found in group Ⅰ. Conclusion The changes of respiratory and hemodynamic functions are observed in children undergoing LNF,and anesthesia management should be enhanced for those within 1 to 12 months old who experience the most significant changes.

Objective To assess the feasibility of using PET molecular imaging to evaluate the therapeutic effects of traditional Chinese medicine FuZhiSan (FZS) on the model of aging Alzheimer's disease (AD) rats. Methods Twenty aged AD rats (Sparague-Dawley rats,male) were randomly divided into FZS treated group (n = 10) and control group (n = 10). Another 10 healthy adult rats were as blank controls. Morris water maze record system was used for cognitive function assessment. Before and after FZS treatment 18 F-fluorodeoxyglucose (FDG) and 11 C-2- [4'-(methylamino) phenyl] benzothiazol-6-ol ( PIB )PET imaging was undertaken. After post-treatment imaging procedures the brain tissues of all animals were taken for histochemical study,such as staining with HE,congo red,amyloid β (Aβ) immunofluorescence,5-bromo-2-deoxyuridine (BrdU) immunofluorescence and NeuN immunofluorescence. Paired t-test was performed with SPSS 13.0 software for the data analysis. Results The cognitive dysfunction of aging AD rats was improved after FZS treatment. The escape latency in FZS treated group was significantly shorter than that of control group ((32.5 ±10.8) s vs (102.6±8.8) s,t =15.7987,P=0. 0001). Diffuse neuronal loss and Aβ deposition were detected in the hippocampus and cortex in the aged AD rats. The imaging data showed that brain glucose metabolism was amended in FZS treated group while the abatement of amyloid deposition was not significant. Immunofluorescence results indicated that the neuronal proliferation was more remarkable in FZS treated group. Conclusions It may be feasible to use PET imaging as a method to evaluate the therapeutic effect in AD rats. FZS may ameliorate memory dysfunction of aged AD rats. Its mechanism may be partly contributed to the enhancement of the neuronal proliferation and survival.

Choosing the right solvent and timely use is the basis of rational drug use and the most direct and efficient way to improve the safety of traditional Chinese medicine injections. This study aimed to evaluate the influence of solvent and drug preparation time on Shuanghuanglian injection inducing pseudo-allergic reactions with mouse mode. The two tests were carried out: (1) Comparative experiment between different solvent: Shuanghuanglian injection preparation to the appropriate concentration with 0.9% sodium chloride injection and 5% dextrose injection, mixed with Evans blue, at one time intravenous injected into mice, 30 minutes later, the mouse ears vascular permeability were observed and compared. (2) Comparative experiment among different preparation time: placed 10 min, 2.5 h, 6 h and 24 h after Shuanghuanglian injection were prepared and then to detect the pseudo-allergic reactions in mice using the same methods as in (1). The results showed that there was no significant difference in the pseudo-allergic reactions in mice which induced by the same dose of Shuanghuanglian injection, respectively with 0.9% sodium chloride injection and 5% dextrose injection preparation, and with the extension of preparation time, the degree of pseudo-allergic reactions of Shuanghuanglian injection was gradually severe.

To evaluated the pseudo-allergic reactions of cordate houttuynia, pulse-activating and Qingkailing injection in mice, the ICR mouse were divided into different test groups, then were intravenously injected with three traditional Chinese medicine injections, positive control compound 48/80 and physiological saline as normal control. All test substances were mixed with 0.4% Evans blue. The reaction and vascular permeability of the ears were observed and measured 30 min after injection. At the same time, the mechanisms of the traditional Chinese injections' pseudo-allergic reactions was studyed. ICR mice were injected with the test substances as above without EB, blood in a part of mice were collected after 5 min, and the level of histamine in the plasma were measured. Blood in the other part of mice were collected after 30 min, and the level of VEGF, TNF-α and IL-10 in the serum were measured. The reasults showed that except the cordate houttuynia injection, pulse-activating injection in 1. 5 times clinical concentration and Qingkailing injection in 3.3 times clinical concentration caused mild pseudo-allergic reactions mainly for vascular permeability, no pseudo-allergic reactions occurred when the concentration of the two injections was below the concentration metioned above; 5 minutes after intravenous injection of the three TCM injections into ICR mice with the highest dose, the levels of histamine in plasma of pulse-activating injection and Qingkailing injection groups were increased significantly, 30 minutes later, the levels of VEGF, TNF-α and IL-10 in the serum of all groups were no significant change compared to normal group. The mouse of pulse-activating and Qingkailing injection groups showed inflammatory changes in ear and lung tissues. It can be conluded that when the dose or concentration increased to a certain extent, pulse-activating and Qingkailing injection could induce pseudo-allergic reactions on ICR mice, the increased histamine realease maybe the main reason for pseudo-allergic reactions of the two traditional Chinese medicine injections. In addition the author preliminary thought that inflammatory mechanisms leading to hyperpermeabilities were the main reason of the traditional Chinese medicine injection's pseudo-allergic reaction.
