OBJECTIVE:To detect the expressions of five gastric cancer cell metastasis associated genes induced by arsenic trioxide METHODS:The expressions of CD44,P53,nm23,H-ras,PCNA induced by arsenic trioxide were examined by immunohistochemistry method RESULTS:Arsenic trioxide induced the decrease of the expressions of CD44,P53,PCNA in gastric cancer cells;the expressions of nm23 and H-ras were not changed by As2 O 3 CONCLUSION:It is tentatively proved that the antineoplastic action of As2 O 3 may be related to the down-regulation of CD44,P53 and PCNA

Objective To study the protective effect of pure carbachol or combined with dietary fiber on intestinal mucosal barrier of rats after diffuse brain injury (DBI).Methods An adult male Wistar rat model of DBI was reproduced by gravitational shock method. The rats injured and survived after resuscitation were divided into three groups: model group (n = 40), carbachol group (n = 40) and carbachol combined with dietary fiber group (combined group,n = 32). In addition, a control group was established by simply an incision performed on the scalp, and the rats could drink freely (n = 5). In the experimental groups, 2 hours after resuscitation the rats began to receive gavage, 6 hours once, the liquid amount 15 mL/kg should be assured in every 6 hours, and if insufficient, normal saline was supplemented. In model group, normal saline 90 mL/kg was given, in carbachol group, carbachol 300μg/kg was administered and in combined group, carbachol 300μg/kg combined with dietary fiber 60 mL/kg was supplied. At 3 (combined group being excluded), 6, 12, 24 and 48 hours after resuscitation, the rats were anesthetized to collect samples and detect the plasma levels of D-lactate and activity of diamine oxidase (DAO) respectively, and the changes of villus height of small intestine were examined by a light microscope.Results The plasma D-lactate levels and the activities of DAO at any time point in the experimental groups were significant higher than those in control group (allP < 0.01). Along with the prolongation of time, the levels of plasma D-lactate and DAO activities in carbachol and carbachol plus diatary fiber groups were gradually lower than those of the model group, and at 48 hours after injury they reached their valley values [D-lactate (ng/L): 6.32±0.79, 7.46±1.67 vs. 17.65±1.53, DAO activity (kU/L): 0.76±0.01, 0.86±0.01 vs. 2.23±0.15]. Under light microscopy, compared with control group, the villus height of small intestinal mucosa at any time point in any experimental group was gradually lowered, and reached the valley values at 12 hours, then gradually increased , and peaked at 48 hours, the villus height in carbachol group and combined group was higher than that in model group (μm: 265.36±10.20, 261.54±10.38 vs. 247.51±9.39, bothP < 0.05).Conclusion When only carbachol is administered into the rat intestine early after diffuse brain injury in rats, beginning from 6 hours after injury, the protective effect of intestinal mucosal barrier is shown, representing decrease of plasma D-lactate level and DAO activity, amelioration of intestinal mucosal damage and protection of intestinal mucosal barrier; under the same above situation, the carbachol combined with dietary fiber was applied, showing the similar above carbachol protective effects.

ObjectiveTo explore the differences of patients with mild cognitive impairment (MCI) and normal elderly individuals in neuropsychology and ApoE genotype polymorphism.Methods23 patients with MCI and 28 normal controls were examined with the neuropsychological test and ApoE phenotypes. The neuropsychological test included mini-mental state examination (MMSE), activities of daily living scale (ADL), Preffer outpatient disability questionnair (POD), Fuld object memory evaluation (FOM), rapid verbal retrieve (RVR), digit span (DS), logical memory (LM), Geometry figures, clock drawing test (CDT), delayed recall, clinical dementia rating scale (CDR), global deterioration scale (GDS), Hachinski ischaemic scale (HIS) and center for epidemiological studies-depression scale (CES-D).ResultsMCI cases achieved significantly lower scores than healthy elderly in all cognitive function measures (P<0.05～0.001)except ADL,POD performance and naming, especially in logical memory and semantic memory, similar with the earlier period of AD. The ApoE genotype polymorphism examination showed that the rate of ApoE epsilon 4 allele carry in MCI patients was around 10 times to that in normal controls.ConclusionIndividuals with MCI appear to be at an increased risk of developing AD. Susceptible neuropsychological marker binding other biomarker, e.g. ApoE, can raise the sensibility and specificity in early diagnosis of AD.

STGC3, a novel tumor related gene, was cloned recently. The previous studies indicated that STGC3 can inhibit the proliferation of CNE2 cell line in vitro. To examine the effect of STGC3 on the tumorigenicity of CNE2 cell line and explore its mechanism in nude mice. The Tet/pTRE/CNE2-STGC3 cell line was planted under the front leg skin of nude mice and induced by doxycycline (Dox). The mRNA and protein level of STGC3 in transplanted tumor tissues were detected with RT-PCR and Western Blotting. The apoptosis ratio of the tumor cell was analyzed with flow cytometry. STGC3, Bcl-2 and Bax proteins were examined by immunohistochemistry method. The results indicated that high level of STGC3 expression can inhibit tumorigenicity of CNE2 cell line in nude mice. Tumor grew slowly, later and smaller. Cell apoptotic percentage increased. Bcl-2 protein expression was down-regulated and Bax protein expression was up-regulated in Tet/pTRE/CNE2-STGC3 cell line (P

Objective To observe the protection of carbachol on intestinal barrier function in patients with trauma. Methods A prospective randomized controlled trial was conducted. Seventy patients after trauma with a definite diagnosis of multiple organ dysfunction syndrome(MODS)from Department of Critical Care Medicine in Hebei United University Affiliated Hospital were included. According to random number table,the patients were divided into a carbachol treatment group(37 cases)and a mosapride citrate treatment group(33 cases),and all the patients in the two groups were treated by antibacterial drugs,supportive agents for organ function,surgery, etc symptomatic treatment. Based on the conventional treatment,in the carbachol treatment group,carbachol was administered through a stomach tube at the dose of 0.2 mg/kg,twice a day,and the dose was doubled if no exhaust or defecation persisted for 3 days after treatment,while in the mosapride group,mosapride citrate was given at the dose of 5 mg once and thrice a day,the therapeutic course of both groups being 7 days. On the 1st,3rd,5th, 7th day after admission,peripheral venous fasting blood in early morning was collected,the activity of diamine oxidase(DAO),expression rates of CD11b+and CD18+in polymorphonuclear neutrophil(PMN),contents of tumour necrosis factor-α(TNF-α)and interleukin-10(IL-10) were detected,and the clinical curative effects were observed. Results Compared to the mosapride citrate treatment group,the total effective rate was significantly higher in the carbachol treatment group on the 7th day after treatment〔70.3%(26/37)vs. 45.5%(15/33),P<0.05〕. The activity of DAO,expression rates of CD11b+and CD18+in PMN,contents of TNF-αand IL-10 in the carbachol treatment group were decreased with the extension of time,and reached valley values on the 7th day,the differences were statistically significant in the comparisons with those in mosapride citrate treatment group at the same time point〔DAO(mg/L):3.21±0.52 vs. 3.93±0.51,CD11b+:(14.89±2.16)% vs.(28.92±1.59)%,CD18+:(53.67±2.44)% vs. (72.46±4.08)%, TNF-α(ng/L):111.44±16.42 vs. 129.73±18.74, IL-10(ng/L):67.71±38.83 vs. 121.45±40.23,all P<0.05〕. At the various time points,the above indexes had no obvious changes in mosapride citrate treatment group. Conclusion Carbachol can ameliorate the ischemic/reperfusion(I/R)injury in patients with intestinal barrier dysfunction after trauma,decrease the release of inflammatory cytokines in vivo,and promote peristalsis of intestinal tract,therefore carbachol has clinical value of protecting intestinal barrier function.

Objective To clarify the position,figure and connections with adjacencies in the pallial thickening(Pth),and provide essential parameters for its function study. Methods The coronal serial sections of 60?m thickness in gekko gecko brain were made by cryo-microtome,and Nissl staining was used.Pictures were taken in each coronal section containing the Pth and the size of Pth in each section was measured.One of them was chosen for the three-dimensional reconstruction.3D MAX was used as the tool software to rebuild the nucleus. Results 1.The Pth was located in the rostral part of the telencephalon,the lateral part of anterior dorsal ventricular ridge,the medial part of the lateral cortex and the ventral part of the dorsal cortex.The length of Pth from the rostral to the caudal end was(912.67?110.96)?m(n=10),the cubage of Pth was about(0.1430?0.0414)?m~3(n=10).2.The Pth could be divided into four segments,the anterior,the middle,the posterior and the terminal segments from the rostral to the caudal end.In the posterior segment,its dorsoventral axis was the longest,and could be divided into two parts: the dorsal and the ventral parts.The boundary of the two parts was clear.Conclusion The Pth is a long,narrow and flat structure;its rostrocaudal axis is longer than its dorsoventral axis,and its dorsal edge is smoother than its ventral edge.In the Pth,its caudal region is larger than its rostral region,and the posterior segment in the caudal region is divided into the dorsal and the ventral cell populations.

Objective To investigate the effect of a fast-track based clinical nursing pathway of hepatic carcinoma on patient satisfaction and job satisfaction of nurses. Methods A total of 91 primary hepatic carcinoma (PHC) patients undergoing elective hepatectomy were enrolled and were divided into two groups by admission time, namely the control group (48 cases) and the experimental group (43 cases). The patients in the control group received traditional perioperative nursing care of hepatectomy, while the cases in the experimental group participated in fast-track nursing pathway. Patient satisfaction and nurse job satisfaction were measured before and after implementation. Results Final analysis included 45 patients in the control group and 40 patients in the experimental group. In the experimental group, the total score of patient satisfaction and the scores of all dimensions (including services and techniques, concern and care, services and techniques and overall satisfaction) were (132.75 ± 13.71), (48.30 ± 6.53), (42.60 ± 4.62), (35.98 ± 3.85), (5.88 ± 0.94), while they were (122.89 ± 16.62), (44.53 ± 7.74), (39.49 ± 5.67), (33.53±4.40), (5.33±1.13) in the control group. And the scores of the experimental group were significantly higher than that of the control group (t=-2.961, t=-2.409, t=-2.753, t=-2.709, t=-2.389, P<0.05). Furthermore,after implementing the fast-track clinical nursing pathway,the total score of nurse job satisfaction and the scores of six factors were (143.23 ± 9.40), (28.45 ± 2.72), (24.82 ± 2.28), (23.05 ± 1.33), (13.91 ± 1.95), (15.05 ± 1.43), (16.64 ± 1.65) while they were (127.36 ± 13.14), (25.68 ± 4.16), (19.64 ± 2.75), (20.23 ± 2.35), (13.23 ± 2.22), (13.68 ± 2.01), (14.50 ± 1.95) before the implementation. The former was significantly better than the latter (t =-12.462,-7.743,-12.670,-6.560,-2.417,-1.483,-6.587,P<0.05). However, no differences were observed in the other two dimensions of wages and benefits andwork-family balance(t =-1.945,-1.312,P>0.05) since the scores after implementation were (13.86 ± 2.12), (7.45 ± 1.57), while that of (13.18 ± 2.30)、(7.23 ± 1.41) were obtained before performance. Conclusions Application of fast- track nursing pathway in perioperative patients with PHC can contribute to promoting the level of patient satisfaction and job satisfaction of nurses and improving nursing quality. It is suggested that this nursing pathway will have more potential value for PHC patients.

Objective To investigate the effect of CT perfusion (CTP) imaging guidance in the treatment of acute cere?bral infarction. Methods Patients (n=200) with acute cerebral infarction who visited our clinic within 6 hours underwent CTP examination and were divided into two groups:penumbra group and non-penumbra group according to their CTP imag?ing (presence of penumbra or not). Recombinant tissue plasminogen activator (rt- PA) was administrated for intravenous thrombolysis in both groups. NIHSS (The NIH Stroke Scale), BI (Barthel Index), mRS (modified Rankin Scores) and hemor?rhagic transformation events of two groups were determined before and after thrombolysis to evaluate its effect and prognosis in these two group. Results Compared with non penumbra group, NIHSS was reduced in penumbra group from 7 days after rt-PA (6.67±3.46 vs 4.76±2.04), and this decrease became obvious at 4 weeks after rt-PA (6.67±3.46 vs 3.68±1.93). Effi?ciency rate at 4 week (60.3%) and good prognosis rate at 3 months(71.7%)were both significantly improved in penumbra group than those in non penumbra group(34.7%,56.8%). Conclusion rt-PA under CTP guidance is effective and safe in the treatment of acute cerebral infarction. The thrombolytic therapy window can be enlarged according to the presence of pen?umbra or not and the bleeding conversion rate remains at low level.

This study aimed to observe the protective effect of momordicine I, a triterpenoid compound extracted from momordica charantia L., on isoproterenol (ISO)-induced hypertrophy in rat H9c2 cardiomyocytes and investigate its potential mechanism. Treatment with 10 μM ISO induced cardiomyocyte hypertrophy as evidenced by increased cell surface area and protein content as well as pronounced upregulation of fetal genes including atrial natriuretic peptide, β-myosin heavy chain, and α-skeletal actin; however, those responses were markedly attenuated by treatment with 12.5 μg/ml momordicine I. Transcriptome experiment results showed that there were 381 and 447 differentially expressed genes expressed in comparisons of model/control and momordicine I intervention/model, respectively. GO enrichment analysis suggested that the anti-cardiomyocyte hypertrophic effect of momordicine I may be mainly associated with the regulation of metabolic processes. Based on our transcriptome experiment results as well as literature reports, we selected glycerophospholipid metabolizing enzymes group VI phospholipase A 2 (PLA2G6) and diacylglycerol kinase ζ (DGK-ζ) as targets to further explore the potential mechanism through which momordicine I inhibited ISO-induced cardiomyocyte hypertrophy.Our results demonstrated that momordicine I inhibited ISO-induced upregulations of mRNA levels and protein expressions of PLA2G6 and DGK-ζ. Collectively, momordicine I alleviated ISO-induced cardiomyocyte hypertrophy, which may be related to its inhibition of the expression of glycerophospholipid metabolizing enzymes PLA2G6 and DGK-ζ.

OBJECTIVE: To analyze the clinical features and pathogenic variant in a Chinese pedigree affected with cleidocranial dysplasia (CCD). METHODS: Clinical data of 8 patients from the pedigree was collected, including physical examination and X-ray images of head, face, spine, limbs, and mouth. Peripheral blood samples were collected from 6 affected members for the extraction of genomic DNA. The proband and other 3 patients were subjected to trio-whole exome sequencing. Candidate variant was verified by Sanger sequencing of the other 2 affected members from the pedigree. RESULTS: This pedigree has included 22 members (8 affected) from four generations. Genetic testing revealed that the proband has harbored a novel pathogenic variant of the RUNX2 gene [NM_001024630: c.1268_1277del (p.P425Afs*56)], which was inherited from her mother and carried by all affected members in the pedigree. The same variant was not detected among the unaffected members, suggesting co-segregation with the phenotype. CONCLUSION The c.1268_1277del (p.P425Afs*56) variant of the RUNX2 gene probably underlay the pathogenesis of CCD in this pedigree. Genetic testing has facilitated the definite diagnosis and enabled prenatal diagnosis.
