HSU17714 gene is a novel human colorectal carcinoma related gene isolated by subtractive hybridization method. The recombinant antisense expressive plasmid of HSU17714 gene was constructed by inserting the partial sequence (2612 bp) of this gene into the multiple cloning site of the vector pREP9 inversely. Then, it was transferred into human colon adenocarcinoma cells (SW1116) through liposome mediation. Obtained from the two-layer soft agarose culture test, flowcytometry test and cell growth rate detection, the data indicated that the antisense HSU17714 could inhibit the growth of SW1116 cells at different degrees. So, a conclusion could be drawn that the antisense HSU17714 gene expressive vector plays a role in the inhibition of SW1116 cell growth.

Objective To explore the value of spiral CT in differentiation between benign and malignant thyroid tumor.Methods CT findings of thyroid tumor confirmed by the pathology in 50 patients,were retrospectively analyzed and in comparison with the data of operation and pathology.Results There were benign tumor(n=35)and malignant tumor(n=15)in this study.All the benign tumors were thyroid adenoma.The malignant tumors included thyroid carcinoma(n=14)and lymphoma(n=1).All the cases of thyroid benign tumors demonstrated clear margin and homogeneous enhancement.Cystic area and curvilinear or mass calcification could be seen in some cases.Some characteristic signs,such as irregular tumor outline,fine discrete granular and irregular calcification,heterogeneous enhancement,invading neighbor structures and cervical lymph node metastasis,could only been seen in thyroid malignant tumors.Conclusion Spiral CT has a notable advantage in differential diagnosis between benign and malignant thyroid tumor.

Objective To study the effect of siRNA targeting survivin and tumor necrosis factor related apoptosis-inducing ligand on the proliferation and apoptosis of hepatocellular carcinoma ( HCC) cells. Methods siRNA eukaryotic expression vector was constructed and the effects of soluble tumor necrosis factor related apoptosis-inducing ligand ( sTRAIL) on HCC cells were observed. Results The recombinant plasmid Psilence ( + )-survivin was successfully constructed. Survivin mRNA expression inhibition ratio reached 73% by RT-PCR. Observed by MTT method sTRAIL failed to inhibit the survival rate of HepG2、HepG2/Silence( - ) cells at 12 h、24 h、48 h when compared to control groups. With the survivin gene being inhibited, the survival rate of HepG2/Silence( + ) cells(0. 518?0. 017) decreased in 12 h compared to control groups (0. 741?0. 005 ) and reached the lowest level in 48 h ( P

With patients' general situation, medication use, occurrence time of adverse drug reaction/event (ADR/ADE), clinical manifestations and prognosis as reference items, a retrospective study was made for 315 cases with ADR/ADE induced by Gastrodin in Chongqing from January 2008 to June 2014, in order to analyze the characteristics of ADR/ADE and provide reference for rational clinical medication. The results showed that among the 315 cases with ADR/ADE, 143 cases (45.4%) were males and 172 cases (54.6%) were females, most of them (74.9%) were aged above 45; 60 cases (19.0%) with ADE were caused by off-label indications and 66 cases (21.0%) with ADE were caused by over dosage; ADR/ADE cases induced by intravenous drip mainly happened within 30 min (85.5%), ADR/ADE cases induced by oral administration mainly happened within 2 h (74.4%), and all of ADR/ ADE cases induced by intramuscular injection happened within 10 min. Totally 593 ADR/ADE cases were reported, which were mainly damages in gastrointestinal system, skin and its adnexa; And 61.9% of ADR/ADE cases were newly reported. It is suggested that medical workers shall learn about the regularity and characteristics of ADR/ADE induced by gastrodin, apply it in clinic with standards, pay close attention to changes of patients' situations and attach importance to the monitoring of ADR/ADE, so as to enhance the safety of medication.

OBJECTIVETo explore the effect and mechanism of hirudin on atherosclerotic plaques in apolipoprotein E knockout (ApoE(-/-)) mice.

METHODSTotally 24 ApoE(-/-) mice, 7-8 weeks old were fed with high fat diets. They were randomly divided into the recombinant hirudin treatment group (drug group) and the model group according to body weight and different dens, 12 in each group. Twelve C57BL/6J mice, 7-8 weeks old fed with high fat diet were recruited as the normal control group. Recombinant hirudin (0.25 mg/kg) was intraperitoneally injected to mice in the drug group from the 10th week old once every other day for five successive weeks. Equal volume of normal saline was injected to mice in the model group. Mice in the normal control group received no treatment. All mice were sacrificed after fed with high fat diet until they were 20 weeks old. Serum levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), high-sensitive C-reactive protein (hs-CRP), E-selectin, interleukin-6 (IL-6), and stromal metalloproteinase-2 (MMP-2) were detected. The plaque/lumen area and extracellular lipid composition/ plaque area were analyzed by HE staining and morphometry. Changes of signaling molecules in store-operated calcium channels, including stromal interacting molecule 1 (STIM1), Orail protein, and transient receptor potential channel 1 (TRPC1) were determined by Western blot. Results Lipid plaque formed in the aorta vessel wall of 20-week old mice in the model group. Compared with the normal control group, serum levels of TC, TG and LDL increased (P<0.01), hs-CRP, E-selction, IL-6, and MMP-2 obviously increased (P<0.01, P<0.05) in the model group; expression levels of STIM1, TRPC1, and Orail significantly increased (P<0.01). Compared with the model group, the plaque/lumen area and the extracellular lipid composition/plaque area significantly decreased in the drug group (P<0.05, P<0.01); serum levels of TC and LDL, hs-CRP, E-selction, IL-6, and MMP-2 obviously decreased (P<0.05, P<0.01); expression levels of STIM1, TRPC1, and Orail were significantly down-regulated (P<0.05, P<0.01).

CONCLUSIONHirudin could significantly improve lipids and endothelial functions of ApoE(-/-) mice, down-regulate expression levels of STIM1, Orai1, and TRPC1, and thus delaying the occurrence and development of atherosclerosis.

Objective To compare the changes in serum levels of high sensitive C-reactive protein (hs-CRP)and uric acid(UA)before and after atorvastatin treatment for the patients with both essential hypertension and hypercholesterolemia,and to evaluate its effects on blood pressure and left ventricular remodeling.Methods One hundred and twenty-six hypertensive patients complicated with hypercholesterolemia were randomized into group A with amlodipine 10 mg/d(n = 65)and group B with amlodipine 10 mg/d plus atorvastatin 20 mg/d(n = 61),for three months continuously.Serum levels of total cholesterol(TC),low-density lipoprotein-cholesterol(LDL-C),high-density lipoprotein-cholesterol (HDL-C),triglyeerides(TG),hs-CRP and UA,as well as blood pressure,were determined for both groups before and after treatment.Left ventricular posterior wall thickness(LPWT)and interventricular septum thickness(IVST)were measured by echocardiography and left ventricle mass index(LVMI)was calculated.Results Serum levels of TC,LDL-C,HDL-C,TG,hs-CRP and UA decreased significantly in gr6up B after three-month treatment with atorvastatin,while serum level of HDL-C increased significantly. And,systolic and diastolic blood pressure reduced in both groups,but significantly lower in group B than those in group A,after treatment(P

Objective To explore the clinical characteristics in patients with histiocytic necrotizing lymphadenitis (also called Kikuchi-Fujimoto' s disease,KD) and meningitis.Methods We reported a patient who developed meningitis preceding the other presentations of KD with abnormal serum autoimmune phenomena,and systematically reviewed 19 cases of KD with meningitis that had been reported worldwide,and analyzed the clinical parameters and treatments.Results The present case was a 25-year-old female subject with serum antinuclear factor antibody and anti-ribonucleoprotein antibody positive.The patient recovered after treatment with steroid and no recurrence was appeared.Among the 19 patients,the average age was 20.2 years,sex ratio was 10:9 (10 female:9 male),7 patients had abnormal serum autoimmune phenomena,7 patients'initial symptom was meningitis and 5 patients were administrated with steroid.Conclusions The onset age in KD with meningitis is earlier than the common KD,and sex ratio in KD with meningitis is close to 1∶ 1.A definitive diagnosis of the disease is determined by a lymph node biopsy at present.

OBJECTIVETo investigate the anatomical features of iliac bone grafts used for mandibular reconstruction and dental implantation.

METHODSSixteen cadavers were dissected. The length, width, height and cortical thickness of the iliac bone were measured with respect to points determined by the relative dimensions of the bone.

RESULTSThe length of iliac bone graft was (77.2 ± 6.1) mm. The height was from (38.2 ± 4.2) mm to (41.9 ± 4.7) mm. The width decreased from iliac crest to base line. The least width 10 mm and 15 mm away from iliac crest were (8.4 ± 2.2) mm and (6.5 ± 2.1) mm respectively. The greatest mean cross-sectional cortical thickness at the intermediate line of the iliac crest was (3.4 ± 0.8) mm.

CONCLUSIONSAnatomical features of iliac bone are suitable for designing bone grafts for mandibular reconstruction followed by dental implantation.

OBJECTIVETo compare the lipid lowering effects of Zhikang Granule (ZKG) and simvastatin.

METHODSForty-five out-patients with hyperlipemia who met the entry criteria were enrolled and randomized into two groups in the ratio of 2: 1, 30 patients in the ZKG group and 15 patients in the simvastatin group. The lipid lowering effects and safety of treatment during the 24-week therapeutic period, as well as the influence of treatment on plasma high sensitivity C reactive protein (hs-CRP) level in patients were observed.

RESULTSNo significant difference between the two groups was observed in serum levels of total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein-cholesterol (HDL-C) and triglyceride (TG) at the 4th, 8th, 12th and 24th week (P > 0.05). However, as compared with baseline, significant reduction of TC and LDL-C in both groups was shown at all the observing time points (P < 0.01), while the changes in TG and HDL-C were insignificant (P > 0.05). The control rates of LDL-C and TC in the ZKG group and the simvastatin group were 86.7% (26/30) versus 100% (15/15) at the 4th week, 80.0% (24/30) versus 100% (15/15) at the 8th week, 53.3% (16/30) versus 60.0% (9/15) at the 12th week, and 90.0% (27/30) versus 93.3% (14/15) at the 24th week, respectively, all showed insignificant difference between groups. No statistical differences were found between groups in levels of plasma transaminase, creatinine, uric acid and hs-CRP (P > 0.05).

CONCLUSIONZKG has a definite effect in lowering LDL-C and TC, and it is safe in long-term administration.
