Objective To investigate the effect of Rho GDP dissociation inhibitor 2 (RhoGDI2) and Bcl-2 in pathogenesis of hypoxic-ischemic brain damage (HIBD).Methods Neonatal 7-day-old Sprague Dawley rats were randomly divided into sham-operation control group,HIBD 6 h group and HIBD 48 h group (n =10 per group).The apoptosis rate of brain cell was measured by flow cytometer and the expression of RhoGDI2 mRNA and Bcl-2 mRNA were detected by Real-time RT-PCR.Results ( 1 ) The ligated cerebral hemisphere of neonatal rats showed obvious edema at 48 h after hypoxia-ischemia.( 2 ) Apoptotic cell appeared at 6 h in HIBD group,the apoptosis rate was ( 1.40 ± 0.12 ) ％.The apoptosis rate obviously increased to (15.86 ±0.98)％ at 48 h after HIBD,which showed a significant increase compared to sham-operation control group ( P ＜ 0.01 ).( 3 ) The expressions of both RhoGDI2 mRNA and Bcl-2 mRNA were 4.12 ±0.74 and 2.55 ± 0.65 respectively in sham-operation control group.In HIBD group,the expressions of both RhoGDI2 mRNA and Bcl-2 mRNA began to decrease at 6 h after HIBD ( 3.19 ± 0.77,1.96 ± 0.36) and decreased furthermore at 48 h after HIBD ( 1.04 ±0.18,1.06 ±0.17 ).The differences of expression levels among three groups were statistically significant (P ＜0.01 ).(4) The expression of RhoGDI2 mRNA positively correlated with the expression of Bcl-2 mRNA ( r =0.831,P ＜ 0.05 ).Conclusion With the emerging of apoptosis after HIBD,the expressions of both RhoGDI2 mRNA and Bcl-2 mRNA are decreased.The imbalance of expression of RhoGDI2 is involved in pathogenesis of HIBD by regulating Bcl-2 expression.

Objective To evaluate the efficacy of gabapentin for prevention of post-thoracotomy pain syndrome (PTPS).Methods Sixty-nine ASA physical status Ⅰ or Ⅱ patients of both sexes,aged 46-69 yr,weighing 47-78 kg,scheduled for elective resection for lung cancer under general anesthesia combined with epidural block,were randomly divided into 2 groups using a random number table:group A (n =36) and group B (n =33).In group A,gabapentin 300 mg was given orally at 2 h before operation and gabapentin 100 mg was given orally three times a day from 1st day after operation until 10th day after operation.Group B received placebo instead of gabapentin.Epidural blockade with ropivacaine and sufentanil was performed before induction of anesthesia and the level of block was controlled at T4-10.Patient-controlled epidural analgesia (PCEA) was performed within 3 days after operation and VAS scores were maintained ≤ 3.The development of pain (numeric rating scale score ＞ 4) within 6 months after operation and the duration were recorded.The consumption of propofol and remifentanil during operation and the number of attempts for PCEA after operation were recorded.The adverse reactions such as postoperative drowsiness,dizziness,fatigue were also recorded.Results Compared with B group,the incidence of pain within 6 months after operation was significantly decreased,the duration of pain was shortened (P ＜ 0.05),and no significant changes were found in the consumption of propofol and remifentanil during operation and the number of attempts for PCEA after operation in A group (P ＞ 0.05).No adverse reactions developed in group B.Mild dizziness and fatigue occurred in 2 patients in group A.Conclusion Gabapentin (continuous application at 2 h before operation and 10 days after operation) can reduce the development of PTPS in patients with no obvious adverse reactions.

Objective To explore the role of plasminogen activator inhibitor-1(PAI-1)in development of progressive fibrosis via the inhibition of extracellular matrix degradation,and to reveal the contributive role of PAI-1 in muscular dystrophy(MD).Methods Expression and cellular localization of PAI-1 protein were examined in frozen muscle specimens obtained via biopsy from 5 patients with duchenne muscular dystrophy(DMD),3 patients with becker muscular dystrophy(BMD),9 patients with congenital muscular dystrophy(CMD) and 4 cases with normal muscle by immunohistochemistry,double immunofluorescence and Western-blot analysis.Results PAI-1 was positive only in vascular endothelial cells of normal muscle.Both immunohistochemistry and Western-blot analysis showed that PAI-1 expression distinctly increased in most dystrophic muscles of MD than that in normal muscles.Double immunolabeling revealed that PAI-1 strongly expressed in cytoplasm and nuclei of regenerating muscle fibers,macrophages,macrophage infiltrating necrotic fibers.Some activated fibroblasts in endomysium and perimysium of DMD and CMD muscles were positive for PAI-1.Conclusions The functional consequence of overexpression of PAI-1 in dystrophic muscles is unknown but the elevated local expression of PAI-1 in diseased muscles of MD and their distinct distribution pattern provide evidence that PAI-1 participate in pathogenesis of MD.

The present study is to investigate the quality changes of ginseng stems and leaves before and after frost. The contents changes of ginsenoside, free amino acid, and total phenolic compounds, as well as DPPH radical scavenging effect before and after frost were measured. The content of 9 ginsenoside monomer in ginseng stems was decreased except for Rg, and Re after frost, but in ginseng leaves was all decreased. The total content of amino acids was decreased in ginseng stems after frost, while increased in ginseng leaves. The content of phenolic compounds in ginseng stems and leaves were both decreased after frost while the ability of DPPH radical scavenging was improved. The factor of frost has great impact on the quality of ginseng stems and leaves.

Objective To characterize the clinical characteristics of lupus mesenteric vasculitis (LMV). Methods Analyzing the clinical, laboratory and treatment data of LMV patients hospitalized from 2002. 1.1 to 2007. 12. 31 retrospectively. Results (1) The three common manifestations were abdominal pain, diarrhea and vomit with the prevalence rate of 77%, 70% and 67% respectively. (2)The majority of LMV cases were active vital organ (28/30), kidney (24/30) and hematological system (18/30) were the main organs of involvement. Ten patients had hydroureteronephrosis, and 8 patients had intestinal pseudo-obstruction at the same time. (3) Systemic lupus erythematosus disease activity index (SLEDAI) score was ≥10 in 80% (24/30) of patients. The progression of LMV was accompanied with new-onset ieucopenia or worsening leucopenia or hypocomplementemia in 10 cases. (4) Blood antinuclear antibodies were positive in 27 patients detected, and anti-SSA antibody was positive in 15 (56%), anti-U1RNP antibody was positive in 14 (52%). (5) Fourteen cases had bowel wall thickening with target sign or mesenteric vessels with palisade or comb sign in contrast CT scan of abdomen. (6)Twenty-seven cases were treated with orally or intravenous medium to high dose steroid therapy and recovered from LMV. Conclusions (1) Abdominal pain, diarrhea and vomit were frequent manifestations of LMV patients. (2) LMV was one of the serious complications of systemic lupus erythematosus(SLE), and usually accompanied by active SLE in other organs. (3) A drop in the white blood cell count or complement C3 titer might be correlate with the occurrence of LMV. It needs to further investigate the relationship between LMV and the high positive rate of anti-SSA and anti-U1RNP antibody. (4) LMV patients responded well to intravenous high dose methylprednisolone.

Objective To test the level of cell factor interleukin (IL)-21,CXCL13 in the plasma of patients with rheumatoid arthritis (RA),and to analyze the relationship between Follicular helper T cells(Tfh)and clinic features and discuss the possible immunological pathogenesis of RA.Methods The Tfh cells were obtained from patients and healthy controls (NC) and detected by Flow cytometery.While the levels of IL-21,CXCL13 in patients and NC were measured by ELISA tests.Those analysis were performed by student's t-test,one-way ANOVA,SNK-q test,Chi-square test,Spearman's correlation and multiple linear regression.Results The expression of CD4+CXCR5+ICOS+ cells (Tfh) in PBMCs of RA was significantly higher than normal controls (3.0±1.2 vs 1.1±0.4,P＜0.01).Meanwhile,the three RA groups of patients were divided to low,moderate and high disease activity groups,and the results showed that the expression of Tfh were increased accordingly (1.8±0.7,2.5±0.6,4.0±1.2).The expression of Tfh in the three groups were all significantly higher than that of controls (P＜0.01).There was a positive correlation between Tfh and DAS28,ESR,CRP,TJC,and bone erosion,RF and anti-CCP respectively.The expression of Tfh in those patients who had bone destruction was higher than those with no or mild bone destructions (2.7±1.1vs 3.4±1.3).The expression of Tfh in patients with un-treated RA patients,when compared to those RA patients who were treated appropriately and those who were not treated appropriately,was decreased significantly.The expression of Tfh in appropriately treated RA patients was lower than that without appropriately treatment.The level of IL-21,CXCL13 was decreased in patients with RA in the order of high,moderate,low disease activity and NC.Conclusion The expression of Tfh and the levels of IL-21,CXCL13 are increased significantly,and are closely related to disease activity and bone ersions.The expression of Tfh is decreased after relevant treatment.These results indicate that the abnormality of Tfh may play an important role in the pathogenesis of RA.

An analysis of the time pattern of outpatients visits to our hospital from 1997 to 2000 led to the discovery of the variation pattern of each outpatient departments workload. This discovery has enabled the managers of the hospital to rationally deploy the manpower and material resources of various departments, make full use of limited resources, readjust the working hours and shifts of different kinds of staff, and work out a flexible system of working hours which is more scientific and more convenient to patients. Implementation of such a system has ensured that prompt delivery of medical service is accessible to patients even at the peak of visiting hours. Hence the reduction of patients time of waiting and the provision of a scientific guarantee for establishing a quality, efficient, low consumption and fast outpatient service system, meeting the medical needs of patients to the maximum and enhancing work efficiency.
