METHODS:Scrophularia ningpoensis,Menispermum dauricum,Radix et Rhizoma Glycyrrhizae in the granules were identified by TLC,and the content of linarin in Yanyan granules were determined by HPLC.RESULTS:The TLC spots were clear with high resolution.The linear range of linarin was 4.64～69.6 ?g(r=0.999 9) and the average recovery rate was 98.65%(RSD= 0.79%,n=6). CONCLUSION:The established standard is suitable for the quality control of the Yanyan granules of concentrated sugar-free type.

Objective To investigate the synergistic effect of 11 β-hydroxysteriod dehydrogenase (11 β-HSD1) and S100A16 on the differentiation of3T3-L1 preadipocytes and its mechanism.Methods Lentiviral vectors PLJM1-11β-HSD1 and PLJM1-S100A16-GFP were respectively constructed and co-transfected into 3T3-L1 preadipocytes.The cell strains expressing 11 β-HSD1/S100A16 were screened with 2.5 μg/ml puromycin for two weeks.Western blot was employed to verify the lentiviral carrier transfection effects.The expressions of marker genes related to the adipocyte differentiation were detected by mean of realtime PCR.Oil red O staining was used to observe the lipid droplet accumulation and the content of triglyceride was measured after differentiation of preadipocytes.The effect of 11β-HSD1 and S100A16 on PPARγ promoter activity was detected by luciferase reporter gene.Results Compared with the empty vector group,the expressions of 11β-HSD1 and S100A16 protein in the lentivirus cotransfected 3T3-L1 cell strain were significantly higher.After 3T3-L1 cell strain co-expressing 1 1β-HSD1 and S100A16 was induced to differentiate for 8 days,the lipid droplets accumulation and triglyceride content were siginificantly increased,along with increased expressions of adipocyte differentiation marker genes such as PPARγ,CCAAT/enhancer binding protein α,lipoprotein lipase,fatty acid synthase,and adipocyte fatty acid-binding protein,in comparison with 11 β-HSD1 or S100A16 overexpression.The result of reporter gene indicated that 11 β-HSD1/ S100A16 enhanced PPARγ promoter activity.Conclusions 11β-HSD1 and S100A16 may jointly promote the differentiation of 3T3-L1 preadipocytes through a synergistic effect on PPARγexpression and play a critical role in the development of obesity.

Objective To observe the effect of methylene blue on the expression of liver inducible nitric oxide synthase (iNOS) in rats with different stages of sepsis.Methods One hundred and twenty-six adult female Wistar rats were randomly divided into three groups: sham operation group, sepsis group and methylene blue group, each group was again subdivided into 0, 6, 12, 18, 24, 30, 36 hours subgroups, each subgroup6 rats. The model of sepsis was established by cecal ligation and puncture (CLP) method, and in the sham operation group, the abdominal incision was performed and the intestinal mesentery was separated only, without ligation and perforation. In methylene blue group, 15 mg/kg methylene blue was injected into a caudal vein at 0, 6, 12, 18, 24, 30, 36 hours after CLP in the rats in corresponding subgroups, respectively; in the sepsis and sham operation subgroups, the same amount of 0.9% normal saline was given. After administration for 6 hours in various groups, the rats were sacrificed and the liver tissue was harvested immediately. The expression of iNOS mRNA of liver tissues was determined by the real-time fluorescent quantitative reverse transcription-polymerase chain reaction (qRT-PCR),and the protein expression of iNOS was determined by Western Blot.Results Compared with sham operation group, the liver tissue expression of iNOS mRNA was significantly up-regulated in sub-sepsis groups at 0, 6, 12 and 18 hours after CLP (2-ΔΔCt: 16.66±2.81 vs. 1.00±0.36, 12.26±5.78 vs. 1.00±0.30, 6.08±1.33 vs. 1.00±0.18, 2.42±0.64 vs. 1.00±0.12, allP < 0.01), after 24 hours the expression of iNOS mRNA had no significant change; the liver tissue expression of iNOS protein was obviously up-regulated in sub-sepsis groups at 6, 12 ,18 and 36 hours after CLP (gray value: 0.350±0.011 vs. 0.210±0.005, 1.460±0.085 vs. 0.090±0.005, 0.230±0.012 vs. 0.18±0.008, 0.310±0.017 vs. 0.200±0.010, allP < 0.01). Compared with sepsis group, the expression of the liver tissue iNOS mRNA was down-regulated in methylene blue subgroups at 0, 12 and 18 hours after CLP (2-ΔΔCt: 9.90±3.06 vs. 16.66±2.81, 1.56±0.58 vs. 6.08±1.33, 1.11±0.15 vs. 2.42±0.64, allP < 0.05), and the expression of iNOS protein was down regulated in methylene blue subgroups at 6, 12, 18 and 36 hours after CLP (gray value: 0.150±0.008 vs. 0.350±0.011, 0.950±0.009 vs. 1.460±0.085, 0.150±0.007 vs. 0.230±0.012, 0.170±0.009 vs. 0.310±0.017, allP < 0.05).Conclusion Zero-24 hours after CLP, the expressions of mRNA iNOS and protein in liver of septic rats are significantly increased; methylene blue can markedly inhibit the expressions of iNOS mRNA and protein in the liver of rats with sepsis.

BACKGROUNDTo study the effect of human papillomavirus (HPV) 16 E6/E7 and TPA (12-O-tetradecanog-1-phorbol-13-acetate) on malignant transformation of human embryo oral tissue.

METHODSRecombinant plasmid with HPV 16 E6/E7 was constructed and transfected into human embryo oral tissue. The oral tissue with HPV 16 E6/E7 gene or without the gene was inoculated into the hypophloeodal of right shoulder in scid mice, respectively. The study was conducted in four groups: the first group was the oral tissue transfected plasmid with HPV 16 E6/E7 plus TPA, which were inoculated into 8 scid mice; the second group was only oral tissue transfected with plasmid with HPV 16 E6/E7 into 6 scid mice; the third group was normal oral tissue plus TPA inoculated into 6 scid mice, and the final group was only normal oral tissue inoculated into 5 scid mice. Three days after inoculation, TPA was injected at the left shoulder of the mice once a week. Twelve weeks after inoculation, tumor was found in 7 scid mice from the first group. HPV 16 E6/E7 gene in tumor tissues was analyzed by PCR.

RESULTSThe rate of tumor formation was 7/8 in the first group; no tumor was found in the other groups. Pathological diagnosis of the tumor was fibrohistiocytoma. HPV 16 E6/E7 gene was detected by PCR in tumor tissues.

CONCLUSIONWith the cooperating action of TPA, human oral tissue containing HPV 16 E6/E7 gene could cause malignant transformation in scid mice.

Objective To discuss the MRI features of sophorae subprostrate intoxication.Methods Four cases with sophorae subprostrate intoxication underwent conventional MRI and diffusion-weighted imaging(DWI)with a 1.5 T MR system.Results In four cases,all cerebellar dentate nuclei showed symmetric patchy hyper-intensity on T_2 weighted images and iso-intensity on diffusion-weighted images as well as hyper-intensity on ADC maps.The bilateral dorsum of the brain stem and thalamus were involved in one ease.Symmetric long T_1 and T_2 signals and high DWI signals with low ADC values in bilateral basal ganglia area were demonstrated in one case with severe symptoms.After treatment,repeated MR images in two cases showed the abnormal signals of dentate nucleus disappeared,and the lesions of basal ganglia area in one case tended to be cystie with longer T_1 and T_2 signals and low DWI signals.Conclusion It is specific for intoxication of sophorae subprostrate to affect the dentate nuclei and lentiform nuclei.MRI and DWI is helpful for the early diagnosis,differential diagnosis and prognosis evaluation of this disease.

Objective To observe the effects of cell cycle inhibitor on astrocytic proliferation and scar formation and to study neuronal apoptosis after focal cerebral ischemia in rats.Methods Ischemic model was established by photochemistry method.T_2-weighted MRI was performed on the 3rd, 7th, and 30th day after focal cerebral ischemia.The expression of glial fibrillary acidic protein(GFAP)and apoptosis was observed by immunofluorescence.The protein levels of GFAP and proliferation cell nuclear antigen (PCNA), CyelinA and CyclinB1 were measured by Western blotting from the ischemic and sham animals finished on the 3rd, 7th, and 30th day.Results A marked and significant reduction of brain infarction volume was found in Olomoucine-treated ischemic animals(2.27%?0.28% , 1.87%?0.19%, 1.08%? 0.18%)as compared with controls(5.10%?0.35%, 4.60%?0.26%, 3.96%?0.28%, P

BACKGROUNDGlaucoma filtering surgery (GFS) is the most common procedure performed in the treatment of glaucoma. Although antiscarring agents help prevent postsurgical scarring and improve glaucoma surgical outcomes, they may be associated with an increased incidence of severe and potentially blinding complications. Poly(DL-lactide-co-glycolide) (PDLLA/GA) is a bioresorbable polymer, which can be prepared with a large range of physical, mechanical, and biological properties and has been widely used in medicine, including as an absorbable suture and a drug carrier and especially as a scaffold in tissue engineering. This study aimed to evaluate the effect of PDLLA/GA on scar formation after glaucoma filtration surgery (GFS).

METHODSForty-eight New Zealand white rabbits were divided into two groups randomly and GFS was performed on the right eye of each. PDLLA/GA membranes were put under the sclera flap for evaluation. GFS with no membrane inserted served as control. Clinical evaluations of intraocular pressure (IOP) and the presence of a filtration bleb were performed at intervals (3 days, 1, 2, 4, 8, 12, 20, and 24 weeks) postoperatively. At each time point, three eyes per group were excised to observe histological changes such as inflammation and scar formation and the expression of collagen type IV, proliferating cell nuclear antigen (PCNA), matrix metalloproteinase-9 (MMP-9), and tissue inhibitor of metalloproteinase-1 (TIMP-1). The expression of connective tissue growth factor (CTGF) mRNA was determined by reverse transcription-polymerase chain reaction.

RESULTSThe lower IOP level and an effective bleb were maintained for a long time after GFS in the PDLLA/GA group. The histological analysis showed less inflammation and scar formation, weaker expression of collagen type IV and PCNA, more intense MMP-9 and TIMP-1, slightly elevated ratio of MMP-9 and TIMP-1, and a smaller increase in CTGF mRNA postoperatively in the PDLLA/GA group but less than the control group (P < 0.05).

CONCLUSIONPDLLA/GA membranes may be promising for preventing fibrosis after GFS.

OBJECTIVETo investigate the nutritional status, and provide evidence for nutritional treatment option.

METHODSA total of 452 patients with gastrointestinal cancer were selected, including 156 gastric cancer,117 colon cancer, and 180 rectal cancer. The nutritional risk screening 2002(NRS2002) was applied to grade the nutritional risk. A multi-frequency bioelectrical impedance analysis was used to measure the patients' body composition. Albumin (Alb), prealbumin(PA), transferring(Tf), retinol binding protein(RBP), red blood cell(RBC), hemoglobin (Hb), haematocrit(Hct) were measured after fasting.

RESULTSThe rate of patients with NRS2002 score more than 3 was 70.5%(110/156) for gastric cancer, 53.8%(63/117) for colon cancer, and 46.7%(86/180) for rectal cancer. The score for impaired nutritional status more than 1 for gastric cancer was higher than that for colorectal cancer(P<0.05), while patients with disease score more than 2 was less for gastric cancer(P<0.05). Body mass index(BMI), obesity degree, fat content, fat percentage, and arm circumference were lower in gastric cancer patients as compared to colorectal cancer patients(P<0.05); but protein percentage, muscle percentage, ratio of muscles of arm, and cell mass percentage were higher in gastric cancer patients(P<0.05). The proportions of patients with low Alb, PA, Tf, BC, Hb, Hct were higher for gastric cancer and colon cancer(P<0.05).

CONCLUSIONPatients with gastric cancer are prone to fat loss and therefore have a higher nutritional risk and malnutrition than those with colorectal cancer. Combination of body composition analysis and laboratory examination may achieve comprehensive evaluation of the nutritional status of patients, and provide the evidence of nutritional therapy by being combined with NRS2002 score.

BACKGROUND AND OBJECTIVESapylin is one of the biological response modifiers. It has been used in the comprehensive treatment for advanced cancer, and its clinical efficacy has been proved. This study was to evaluate the effect of preoperative intraperitoneal injection of Sapylin in treatment of advanced gastric cancer.

METHODSSeventy-nine patients eligible for radical gastrectomy were randomly divided into the treatment group (Sapylin + mitomycin C, 40 patients) and the control group (mitomycin C alone, 39 patients). In the treatment group, 5 KE Sapylin was injected intraperitoneally 48 h before operation and 4 mg of mitomycin C was injected into peritoneal cavity before the closure of the peritoneum. In the control group, only 4 mg mitomycin C was injected into peritoneal cavity before the closure of the peritonium.

RESULTSThere was no operative mortality or duodenal stump leakage in the two groups. Postoperative complications were anastomotic leakage (2.5%, 1/40) and incision rupture (2.5%, 1/40) in the treatment group, and incision rupture (2.6%, 1/39) in the control group, with no significant difference between the two groups (P > 0.05). The 3-year survival rate was significantly higher in the treatment group than in the control group (76.5% vs. 49.4%, P < 0.05).

CONCLUSIONSPreoperative intraperitoneal injection of Sapylin can raise the 3-year survival rate after radical gastrectomy , without increasing the incidence rate of operative complications. Preoperative intraperitoneal injection of Sapylin is therefore a valuable therapy for advanced gastric cancer in clinic.
