Objective To study the effects of the compound xueshuantong capsule ( FXC) against cerebral ischemia and hypoxia in mice. Methods KM mice were randomly divided into the sham operation group ( normal control group) , model control group, positive control group and FXC at high-,medium-and low-dose(0. 75,1. 50,and 2. 25 g·kg-1 ) groups. After intragastric administration for 7consecutive days,cerebral ischemia model was established by unilateral carotid arteries ligation. The cerebral water content and stroke index were recorded. The viability of the mice was determined by testing atmospheric hypoxia,sodium nitrite poisoning and acute cerebral anoxia. Results FXC decreased water content and stroke index of the mice suffered from unilateral carotid artery ligation dose-dependently (P<0. 05,P<0. 01) . It also prolonged the survival of mice by tolerating absence of oxygen,sodium nitrite poisoning and acute cerebral anoxia (P<0. 05,P<0. 01). Conclusion FXC has a protective effect on cerebral ischemia and hypoxia in mice.

BACKGROUND:Studiesin vitro have suggested that icarin can attenuate lipopolysaccharide (LPS)-induced acute pneumonia. Is the anti-inflammatory effect of icarin stil valid in the presence of wear particles? OBJECTIVE:With studiesin vivo andin vitro, to investigate the regulatory effect of icarrin on titanium particle-induced inflammatory reaction. METHODS:(1) Studiesin vivo: Eighty male C57BL/6 mice aged 6-8 weeks were randomly divided into four groups: control group, icarin group, titanium particle group, and titanium particle+icarin group. Mice in the titanium particle group and titanium particle+icarin group received surgical procedure, and sterile and endotoxin-free titanium particles were implanted on the calvaria surfaces to induce inflammatory reaction. Mice in the control group and icarin group received the same surgery, but no wear particles were implanted. Then icarin was given oraly to mice in the titanium particle group and titanium particle+ icarin group with a dose of 200 mg/kg per day for 2 weeks from the day of modeling. Mice in the control group and icarin group were given oraly the same dose of placebo. Two weeks later, tumor necrosis factor-α and interleukin-1β at protein and mRNA levels were respectively detected with enzyme-linked immunohistochemical (ELISA) and quantitative real time reverse transcription PCR (qRT-PCR) analysis. (2) Studiesin vitro: Mouse monocyte/macrophage RAW264.7 cels were cultured with different conditioned media: control group, nuclear factor receptor ligand кB (RANKL); icarin group, RANKL+icarin; titanium particle group, RANKL+titanium particles; titanium particle+icarrin group, RANKL+icarin+titanium particles. Titanium particles stimulated RAW264.7 cels were co-cultured with RANKL and icarin for 72 hours. Tumor necrosis factor-α and interleukin-1β at protein and mRNA levels in the supernatant were detected with ELISA analysis and qRT-PCR, respectively. RESULTS AND CONCLUSION: (1) Resultsin vivo: icarin treatment obviously decreased titanium particle-induced inflammatory cellinfiltration and made the thickness of periosteum thinner, down-regulated tumor necrosis factor-α and interleukin-1β expressions at protein and mRNA levels. (2) Results in vitro: when RAW264.7 cels were stimulated with titanium particles for 72 hours, tumor necrosis factor-α and interleukin-1β expressions at protein and mRNA levels in culture media increased obviously; when icarin was administrated, tumor necrosis factor-α and interleukin-1βexpressions at protein and mRNA levels down-regulated significantly. These results suggest icarin can obviously suppress titanium particle-induced inflammatory reactionin vivo andin vitro.

OBJECTIVETo identify the genetic alterations in nonsyndromic cleft lip and palate (NSCLP).

METHODSComparative genomic hybridization was applied to investigate the genomic imbalance (the gain or loss of genetic material) in 7 cases of NSCLP.

RESULTSIt showed that the loss of chromosome DNA copies happened in chromosome 6, 7, 10, 13, 14, 16, 20, 22 and the gain of chromosome DNA copies happened in chromosome 5, 15, 18, 19. Conclusions 13q had a high frequency (71.4%) of chromosome loss.

CONCLUSIONSAbnormal chromosome DNA copies happen in all the patients with NSCLP. Most of the patients have chromosome DNA copies loss. It suggests that loss of inhibitory gene may be related to the NSCLP. The related inhibitory gene may locate in 13q.

Objective To explore the relationship between the histological alterations of Oddi sphincter lesions and clinical manifestations. MethodsFrom October 1995 to May 2003, biopsies of Oddi sphincter were undertaken during transduodenal sphincteroplasty (TSP) in 32 cases. Specimens were stained with Van Gieson Mason staining. ResultsThirty one out of 32 specimens were found with histological alterations in Oddi sphincter including diffuse fibrosis in 87 1% (27/31) , adenomyosis in 2 cases and chronic inflammatory infiltration in 2 cases. Impacted stone in the terminal common bile duct, benign papillary stenosis and visible postpancreatitis parenchymal changes were all found accompanying severe fibrosis of Oddi sphincter. ConclusionIn patients with impacted stones in the ampulla, intracholedochal sludge with recurrent cholangitis, and relapsing pancreatitis, endoscopic sphincterotomy is recommended.

Objective To observe the effect of atorvastatin on mixed dyslipidemia in type 2 diabetic patients.

Objectives To investigate the bacterial pathogens and their antibiotic resistance in children with pneumonia in Suzhou area. Methods Sputum specimens of 8179 hospitalized children with pneumonia from October 2005 to September 2011 were collected by sterile negative pressure aspirator and then cultured. The incidence of positive bacteria was tested by Kirby-Bauer method and broth dilution method, and their antibiotics resistances were analyzed. Results A total of 2391 of 8179 children were infected with positive rate of 29.23%. A total of 2552 strains of bacteria were detected with Streptococcus pneumoniae (42.40%), Haemophilus inlfuenzae (14.81%), Moraxelle catarrhalis (11.01%), Staphylococcus aureus (8.50%) and Escherichia coli (5.02%) as the most common strains. The infection rate of different bacterium was related to age, season and the type of pneumonia (all P<0.001). The tendency of antibiotic resistances in 2 140 bacterial isolates was found increased by the susceptibility test. Conclusions Streptococcus pneumonia and Haemophilus inlfuenzae are the most common bacterial pathogens in children with pneumonia in Suzhou area. The positive rate of different bacterium was related to age, season and the type of pneumonia. Attention must be paid to the rational use of antibiotics to reduce drug resistance.

This study was purposed to investigate the role of cytokines in pathogenesis of lymphoma-associated anemia. The levels of IFN-γ, IL-1β, IL-6, TNF-α and EPO in serum from 45 lymphoma patients and 12 normal controls were detected by using ELISA, the EPOR level on bone marrow cells were detected by flow cytometry, the CFU-E of bone marrow cultured in vitro was counted under inverted microscope. The results showed that 25 (55.6%) out of 45 newly diagnosed lymphoma patients had anemia before diagnosis, 13 (28.9%) had anemia during therapy, 7 (15.5%)never had anemia. The IFN-γ and TNF-α levels in serum of patients with moderate and severe anemia were significantly higher than those in patients with mild anemia and without anemia as well as normal controls. The EPO, IL-6 and IFN-γ levels correlated negatively with Hb concentration in patients, the EPOR level in patients without anemia significantly higher than that in patients with anemia and normal controls. The bone marrow CFU-E amount in patients showed positive correlation with Hb and EPOR levels. It is concluded that the increased IFN-γ, TNF-α and IL-6 may contribute to the anemia in lymphoma, and yet the EPO and EPOR levels are elevated to balance negative regulatory effects on hematopoiesis and maintain normal hematopoiesis.
