Objective To explore the interfering effect of mucosal evolution on the budesonide treatment for chronic rhinosinusitis with nasal polyps after endoscopic surgery (ESS). Methods 174 cases of type Ⅱ stage 3 and type Ⅲ chronic rhinosinusitis with nasal polyps were randomly divided into experimental group (94 cases) and control group(80 cases). After ESS, budesonide was given to the experimental group (128 μg each side per day), but not to the control group. The comparison of mucosal edema, nasal pus accumulation, sinus meatal window, and epithelia of operation cavity were carried out respectively between two groups. Results 4 weeks later, class Ⅰ in experimental group was 46.8% (44/94), in control group was 30.0% (24/80) (P<0.05); 4 to 12 weeks later, the transfor-marion from class Ⅱ to Ⅰ in experimental group was 90.0% (45/50), in control group was 57.1% (32/56) (P<0.01); 12 weeks later, the total class Ⅰ in experimental group was 94.7% (89/94), in control group was 70.0% (56/80) (P < 0.01). The difference between 2 groups was of statistical significance. Conclusion Emphasizing the importance of integrated treatment after operation, ESS for the patients of sinusitis with nasal polyps was feasible, meanwhile, continuous use budesonide could alleviate mucosal edema, lessen conglutination, accelerate epithelia, and prevent recurrence of nasal polyps.

Objective:To investigate the effects of different doses of rosuvastatin on lipid levels in elderly patients with CHD complicated with hyperlipidemia.Methods:120 elderly patients with coronary heart disease admitted in our hospital were retrospectively chosen.By lipid examination,they were all hyperlipidemia.According to the dose of rosuvastatin,they were divided into three groups,and 40 cases in each group.They were given 5 mg,10 mg and 20 mg treatment,respectively.After 2 months,the changes of blood lipid level and the clinical effective rate were compared before and after the treatment.Results:①The blood lipid levels HDL-C [(1.17 ± 0.62) mmol / L] was significantly higher than the other two groups.LDL-C [(3.67 ± 0.83) mmol / L],TC [(4.36 ± 0.96) mmol / L] and TG [(1.68 ± 0.94) mmol / L] were significantly lower than those of the other two groups (P ＜0.05).②The effective rate of treatment in the 20mg group (97.5％) was significantly higher than that in the 5mg group (87.5％) and the 10mg group(85.0％).Conclusions:Rosuvastatin can treat coronary heart disease complicated with hyperlipidemia in elderly patients.The dosage of 20 mg can improve the blood lipid level of the patients,is an effective and convenient method,and with high therapeutic efficiency.

Objective To evaluate the accuracy of endoscopic ultrasonography (EUS) in preoperative TNM staging of gastric cancer.Methods EUS and abdominal helical computed tomography (HCT) were performed one week before the surgery in 126 gastric cancer patients who would receive surgery to determine the depth of tumor invasion (T),lymph node metastasis (N) and distant metastasis (M) stage and which were also compared with pathologic TNM stage after surgery to evaluate the accuracy of EUS in TNM staging.Pairing x2 test was performed for data analysis.Results Compared with pathologic TNM stage after surgery,the accuracy of EUS in T1,T2,T3 and T4 staging of gastric cancer were 84.6％,14/18,82.0 ％ and 85.7％ respectively.The accuracy of EUSin N0,N1,N2 and N3 staging of gastric cancer were 74.2％,75.0％,57.9％ and 5/17 respectively.The accuracy of HCT in N0,N1,N2 and N3 staging of gastric cancer were 80.6％,75.0％,73.7％ and 12/17 respectively.The accuracy of EUS was similar to HCT in N0 and N1 stage.For N2 and N3 stage,HCT was obviously better than EUS (x2 =4.89,P=0.027; x2 =13.88,P＜0.01).The accuracy of EUS and HCT in M1 stage of gastric cancer were 36.4％ and 95.5％respectively,HCT was better than EUS in M1 determination (x2 =7.90,P=0.001).Conclusions The clinical application value of EUS in the preoperative gastric cancer T staging was high,however the accuracy in determining lymph node metastasis N2 and N3 staging and distant metastasis M staging should be improved.In order to acquire more accurate preoperative TNM stage to guide the treatment selection,the combination with HCT examination is necessary.

This study investigates the protective role of IMM-H004, a novel coumarin derivative, on hepatic ischemia-reperfusion injury (HIRI) in mice. All animal experiments in this paper have been approved by the Ethics Committee of Institute of Materia Medica, Chinese Academy of Medical Sciences. The experimental animals were divided into three groups, including sham group, model group, and IMM-H004 treatment group. Serum biochemical indicators were detected and H&E staining was used to assess liver damage. Real-time quantitative PCR (qPCR) was performed to analysis the mRNA content of inflammatory factors. Immunohistochemistry and immunofluorescence were used to observe neutrophil infiltration. Western blot was used to examine the protein levels of NOD-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein (ASC), cysteinyl aspartate specific proteinase-1 (caspase-1), and interleukin-1β (IL-1β). The results showed that IMM-H004 could significantly reduce the serum levels of alanine transaminase (ALT), aspartate transaminase (AST), lactate dehydrogenase (LDH). H&E results showed IMM-H004 could alleviate liver damage caused by HIRI. The mRNA expression of tumor necrosis factor-α (TNF-α), IL-1β, and interleukin-6 (IL-6) were decreased by IMM-H004 administration. Meanwhile, IMM-H004 could markedly inhibit neutrophil infiltration. Furthermore, IMM-H004 could significantly down-regulate the protein expression of NLRP3, ASC, caspase-1, and IL-1β, inhibiting the activation of NLRP3 inflammasome pathway. Our results confirmed that IMM-H004 could protect mice from HIRI and provide a theoretical foundation for IMM-H004 application for treating HIRI.

Objective To evaluate the incidence of aortic valve calcification,and the correlation between valve function and commonly encountered disease in the aged patients.Methods Totally 996 patients who underwent ultrasonic cardiography (UCG) in our hospital were included.They were divide into elderly group and non elderly group,and the elderly group was divided into calcification subgroup and non calcification subgroup.The calcification,stenosis and regurgitation of aortic valve were detected by UCG,and risk factors of calcification were evaluated by Logistic regression analysis.Results The incidence of calcification was higher in elderly group than in non elderly group [71.8％ (526/733) vs.14.6％ (34/233),x2＝237.10,P＜0.01].In elderly group,the incidence of aortic valve stenosis was 2.1％ (11/526) in calcification subgroup and 1.9％ (4/207) in non calcification subgroup (x2＝0.81,P＞0.05).In elderly group,the incidence of aortic valve regurgitation was 63.3％ (333/526) in calcification subgroup and 19.3％ (40/207) in non calcification subgroup (x2＝116.10,P＜0.01).The hazard ratio of aortic valve calcification in different diseases were as follows:hypertension (OR＝2.06,95％CI:1.400-3.031),coronary heart disease (OR＝3.46,95％CI:2.217-5.384),diabetes mellitus (OR ＝ 2.66,95％CI:1.652-4.278),renal dysfunction (OR＝ 2.34,95％ CI:1.415-3.869),osteoporosis (OR＝ 2.33,95％CI:1.119-4.838).Conclusions The incidence of calcification,mainly causing aortic valve regurgitation,is high in elderly patients.Patients with hypertension,coronary heart disease,diabetes mellitus,renal dysfunction and osteoporosis are prone to the development of aortic valve calcification.

Background Deficiency of neurotrophic factor is associated with the damage of optic nerve in glaucoma.Reaserches showed that ectopically applied neurotrophic factor has a transient neuroprotective effect in glaucoma model,and the viral expression of adeno-associated neurotrophie factor may provide long-term supplementation of neurotrophic factor and neuroprotection in tissues.Objective The present study Was to investigate the neuroproteetive effect of adeno-associated viral(AAV)-mediated brain-derived neurotrophic factor (BDNF)on retinal ganglion cells(RGCs)in DBA/2J mice with experimental glaucoma. Methods 10 clean DBA/2J mice were administered intravitreal injection with 1 microliter of AAV-BDNF-GFP in the left eyes at the age of 6 months,and the right eyes were injected with the same volume of saline solution as control.Intraocular pressure (IOP)was measured with Tonolab in the mice every month.Retinas were obtained after 3 months for the investigation of GFP expression in RGCs using fluorescence microscopy.Immunohistochemistry Was performed by applying TUJ1 and Cy3 antibodies to identify surviving RGCs. Results The IOP of DBA/2J mice were 11.90 mmHg and 11.40 mmHg in the right eyes and left eyes,respectively,at 4 months.The IOP of DBA/2J mice began to rise at 5 months and reached its peak in 8 month-old mice.There was no statistically significant difference in IOPs between the right eyes and the left eyes from 4 month-through 9 month-old mice(t=-1.78-0.61,P=0.11-0.90).Three months after intrlavitreal injection of AAV-BDNF-GFP,GFP was positively expressed in RGCs of retinas with the expression rate of 46.33%±8.08%.The over-expression of BDNF led to more RGCs survival than the control eyes (3168.13±1319.33/mm2 vs 2024.81±796.38/mm2,t=2.75,P=0.02). Conclusion These data suggest that BDNF can exert a protective effect in DBA/2J glaucoma mice.

Objective To investigate the effect of bone marrow mesenchymal stem cells (BMSCs) transplantation on angiogenesis and functional recovery after focal cerebral ischemia in rats.Methods BMSCs were isolated and cultured using the whole bone marrow adherent method,and conducted phenotypic identification using flow cytometry analysis of surface positive antigen of CD29,CD90 and the negative antigen of CD34,CD45.Rats were subjected to middle cerebral artery occlusion (MCAO) for 90 minutes,and divided into three groups randomly,the sham group,model group and BMSCs group.24 hours after cerebral ischemia,rats were injected with 1 ml BMSCs solution (1 × 106 cells/ml) or PBS via the tail vein.The modified neurological severity score(mNSS) test,the corner test and the adhesive tape test were used to evaluate sensorimotor function on the 1,7,14 and 28 days after ischemia.Infarcted volume was detected by toluidine blue staining,and the numbers of vWF positive microvessels and vascular endothelial growth factor (VEGF) positive cells in the ischemic boundary were determined by immunofluorescence.Results By flow cytometric analysis,the cell phenotype of passage 3 BMSCs showed that CD29,CD90,CD34 and CD45 were 98.3％,97.4％,0.2％ and 4.8％,respectively.Compared with the model group,BMSCs significantly reduced the score of mNSS(P＜0.01),the number of right turn of corner test(P＜0.05),latency of removal adhesive tape(P＜0.05) and the infarcted volume (P＜0.01).The numbers of vWF positive vesscls and the VEGF positive cells were (42.97±8.64)/mm2 and (54.83± 10.66)/mm2 at the boundary zone in model group 14 days after ischemia,respectively.BMSCs significantly increased the numbers of vWF positive vessels ((69.43± 7.29)/mm2) and VEGF positive cells ((78.70±6.16)/mm2,P＜0.01).Conclusion BMSCs can improve the functions of cerebral lesions after cerebral ischemia,which may be associated with the enhanced angiogenesis and VEGF expression in the ischemic boundary.
