Objective To investigate the effect of bone cancer pain on emotion and NMDA re-ceptor NR2B subunit expression level in anterior cingulate cortex (ACC)in rats.Methods One hun-dred and fifty healthy male Wistar rats weighing 200-250 g aged 3 months old were randomly divided into 3 groups (n = 50 in each group):sham operation group (group S),bone cancer pain group (group BCP),RO25-6981 group (group RO).The BCP model was established by inoculating Walker 256 breast cancer cells into right intra-tibial.Rats in group S were given the same dose of d-hanks. Group RO was injected intraperitoneally with RO25-6981 (5 mg/kg/d)on the day of inoculation, while rats in the group S and group BCP were given the same dose of normal saline.Mechanical with-drawal threshold (MWT)and thermal withdrawal latency (TWL)of right hind legs were measured on day 7,10,14 after inoculation respectively.Elevated plus-maze test was carried out to investigate the effect of bone cancer pain on emotion in rats after pain threshold detection,then the percentage of the times entering the open arms (OE)and the percentage of the time staying in the open arms (OT) duration the total period were evaluated.Then the anterior cingulate cortex tissue was removed to e-valuate the NR2B protein and mRNA expression levels by RT-PCR,Western blot and immunofluo-rescence methods on day 14 after elevated plus-maze test.Results All the parameters did not differ with significant difference between group S and group RO.MWT decreased and TWL shortened on day 7,10,14 after inoculation in group BCP compared with those before inoculation and those of group S and group RO.OE and OT in group BCP reduced remarkably than those before inoculation and those of group S and group RO.Relative absorbance of NR2B mRNA,the expression of NR2B pro-tein,average NR2B relative fluorescence intensity value is obviously higher than that of group S and group RO (P <0.05).Conclusion Bone cancer pain can induce pain-related aversion and anxiety-like behavior of rats,and the mechanism may be related to the high expression of NR2B in anterior cingu-late cortex.

Objective To investigate effect of propofol total intravenous anesthesia and sevoflurane inhalation anesthesia on perioperative inflammatory response in patients with lung cancer.Methods Forty patients with simple resection of lung cancer were selected in our hospital.They were divided into observation group and control groups according to random sampling method (n=20).Observation group was given propofol total intravenous anesthesia while control group received sevoflurane inhalation anesthesia.The serum concentrations of MMP-9,TNF-α,IL-6 were compared at the T0 (immediately before the induction of anesthesia) , T1 (1 hour after surgery) , T2 (end of the surgery immediately) , T3 (24 hour after surgery) . Results Compared with the T0 period,the serum concentrations of MMP-9,TNF-αand IL-6 at the T1,T2,T3 periods were increased significantly in the both groups(P<0.05);the concentrations of TNF-α, IL-6 were lower significantly in observation group compared with control group (P<0.05) . Conclusion Propofol anesthesia for resection of lung cancer patients can significantly reduce the inflammatory response.

OBJECTIVE: To study the relationship between the infection of hepatitis B virus (HBV) in gastric mucosa and the syndrome of disharmony between liver and stomach. METHODS: Subjects were divided into 2 groups: 30 patients with chronic hepatitis B (CHB) and the syndrome of disharmony between liver and stomach in hepatitis group, and 30 patients with chronic gastritis and the syndrome of disharmony between liver and stomach in gastritis group. Liver function and the markers of HBV were detected. The contents of HBV-DNA in serum and in gastric mucosa were assayed respectively by fluorescence quantitative polymerase chain reaction (FQ-PCR). RESULTS: (1) The incidence of gastric mucosal lesion in hepatitis group was up to 96.7% (29/30). (2) Scores of the syndrome of disharmony between liver and stomach in hepatitis group were significantly lower than those in gastritis group (P<0.05). The positive rates of HBV-DNA in serum, gastric fundus, body and antrum were 56.7%, 76.7%, 76.7% and 70.0%, respectively. (3) A positive correlation was found not only among the content of HBV-DNA in serum and the contents of HBV-DNA in gastric mucosa (r=0.66-0.94, P<0.01), but also among the contents of HBV-DNA in serum, gastric mucosa and the total score of the syndrome of disharmony between liver and stomach in hepatitis group (r=0.36-0.52, P<0.05). CONCLUSION: The infection of HBV is involved in the syndrome of disharmony between liver and stomach. Gastric mucosal lesion is universal in CHB patients with the syndrome of disharmony between liver and stomach.

BACKGROUND: Previous experiments have shown that transforming growth factor-?1 (TGF-?1),matrix metalloproteinase-2 (MMP-2) and tissue inhibitor of metalloproteinase-1 (TIMP-1) play an important role in chronic allograft nephropathy,but the mechanisms remains unclear. OBJECTIVE: To investigate the expression and significance of TGF-?1,MMP-2 and TIMP-1 in the renal tissues of chronic allograft nephropathy and normal renal tissues. DESIGN,TIME AND SETTING: A histological and morphological control observational experiment of cytology was performed at Pathological Laboratory of the 175th hospital from June to October 2008. PARTICIPANTS: The transplanted renal tissues extracted from 24 patients with chronic allograft nephropathy were used in the experiment,and the normal renal tissues in 10 patients were assigned as controls. METHODS: Immunohistochemical staining was performed in all the renal tissues. All the renal tissues were fixed with formaldehyde and embedded by paraffin wax. Then the sections were prepared with a thickness of 3 ?m,and were then closed with normal non-immune serum. Subsequently,the sections were incubated as follows: primary antibody,secondary antibody,streptavidin peroxidase complex,and diaminobenzidine (DAB),followed by HE counterstaining. The sections were cleared and coverslipped. MAIN OUTCOME MEASURES: The expressions of TGF-?1,MMP-2 and TIMP-1 in the renal tissues were observed by immunohistochemical staining. The relationships among TGF-?1,MMP-2 and TIMP-1,as well as between them and the grade of chronic allograft nephropathy were analyzed. RESULTS: Qualitative analysis: The TGF-?1,MMP-2 and TIMP-1 showed strongly positive expressions in the cytoplasm and membrane of renal tubular epithelial cells in transplanted renal tissues. Quantitative analysis: There were significant differences in expression of TGF-?1,MMP-2 and TIMP-1 between in transplanted renal tissues and in normal renal tissues (P
