Objective To investigate the change of blood pressure and heart rate in patients of essential hypertension combined with cervical spondylosis in head-up tilt and its potential mechanism. Methods The hypertensive patients were divided into cervical spondylosis group(23 cases) and without cervical spondylosis group (26 cases) by clinical symptom and X-ray machine,CT.MRI and color ultrasonography,then their blood pressure, blood glucose and lipid were measured,and the changes of blood pressure and heart rate were obtained in head-up tilt. Results There was significant difference of blood pressure change between the hypertensive with and without cervical spondylosis(4(-21 ～ 14 mm Hg v. s. -9(-27～-3)mm Hg,P<0. 01),and there was also difference of heart rate change between the hypertensive with and without cervical spondylosis(2(-1 ～14) bpm v. s. 5(-2 ～11) bpm, P < 0. 01). Conclusions There is no decline in blood pressure in the hypertensive with cervical spondylosis in head-up tilt and this might be due to the exciting of sympathetic nerve.

The post-stroke depression refers to a affective disorders within 2 to 3 years after stroke in patients with stroke.Its main features are depressed mood,decreased interest,irritability,pessimism,and slow thinking,etc.Usually the symptoms will last for more than 2 weeks.It is one of the most common complications of stroke and may seriously affect the rehabilitation and quality of life of patients.Some patients even have suicidal tendency.Early intervention is very important for late neurological recovery in patients with stroke.It can not only improve cognitive function,but also reduce the morbidity and mortality.This article reviews the treatment of post-stroke depression.

Background and purpose:Backgrounds and Objective: Oxaliplatin is a third-generation platinum compound,there are some distinct differeuces in mechanism between cisplatin and oxaliplatin,and oxaliplatin is less toxic Poorly differentiated cartinoma is the most common histological type,for nasopharyngeal carcinoma,although radiotherapy is the basic therapeutic approach to nasopharyngeal carcinoma,chemotherapy is also important for recurrent and metastatic nasopharyngeal carcinoma,so in this work we analyzed the effects of oxaliplatin on nasopharyngeal carcinoma cell lines in vitro.Methods:CNE2 was incubated with oxaliplatin at various concentrations and times,cell growth inhibition was assessed by MTT-microculture tetrazolium assay,cell-cycle kinetics and apoptosis were analyzed by flow cytometry and microscopy transmission electron.Results:Growth of CNE2 cells was significantly inhibited in a dose-dependent and time-dependment fashion.The inhibition of cell growth inhibition was(95.6?0.7)% after incubation with 100 ug/ml oxaliplatin for 48 hours,the cell was arrested at G_(2)/M and apoptosis was induced.When CNE2 cells were treated with oxaliplatin at the concentration of 0、0.03、4.0、100 ?g/ml,the rates of CNE2 cell apoptosis were(0.19?0.17)% 、(0.37?0.09)%、(5.50?1.08)%、(9.43?0.09)%,respectively.24 hours after 20 ?g/ml the CNE2 cells were characterized by chromatin condensation,chromatin crescent formation,nucleus fragmentation and apoptosis body by transmission electron microscopy.Conclusions:Oxaliplatin suppresses the growth of CNE2 cells in vitro by causing cell-cycle arrest and cell apoptosis.

Objective To evaluate the antiinflammatory effect of ulinastain( UTI) with ghrelin( GHL) on amelioration of small intestine dysfunction and its possible mechanisms in endotoxemia rats. Methods Animals were received intraperitoneal injection with lipopolysaccha-ride(LPS,15 mg/kg)as a endotoxemia model. 60 male SD rats were randomly divided into control group(CON group),LPS group,UTI group,GHL group,and UTI+GHL group. Microstructure of small intestinal submucosa was observed with HE staining. Dextran blue-2000 (BD-2000)was drenched for calculation of propulsion rate of the small intestine. The level of tumor necrosis factorα(TNF-α),IL-6 and HMGB1 in serum and small Intestinal mucosal tissue were determined by enzyme linked immunosorbent assay( ELISA) . RealTime-PCR was administrated for detection of rat defensin-5 mRNA(RD-5)and trefoil factor family-3(TFF-3)mRNA. All above measurement were taken re-spectively at 12 hours and 24 hours after LPS injection. Results HE staining shows that UTI+GHL group significantly alleviate the damage of intestinal microtructure caused by LPS when compared with UTI group and GHL group. The UTI+GHL group markedly increased expres-sion of RD-5 and TFF3 mRNA than those of UTI and GHL group in small Intestinal mucosal tissue (P<0. 05). Both the GHL group and the UTI+GHL group significantly enhanced the function of intestine motility,but the propulsion rate of UTI+GHL group was significant higher than that of GHL group(P<0. 05). In LPS group,the level of TNF-α、IL-6 and HMGB1 both in serum and intestinal mucosa tissue were markedly increased(P<0. 05),but those of UTI group,GHL group and UTI+GHL group were significantly decreased when compare to LPS group after the drugs administration at 12 and 24 hours. Conclusion UTI combined with GHL can significantly improve the intestinal func-tion of mucosal barrier and the motor through the inhibition of both systemic and intestinal mucosal inflammatory reaction in the process of en-dotoxemia.

OBJECTIVE: To establish a method of on-line matrix elimination together with ion chromatographic for determination of residual tetraethylammonium bromibde(TEAB) which acts as phase transfer catalyst in clopidogrel sulfate. METHODS: An ion excluding column Dionex IonPac NG1 was used for the separation of TEAB from clopidogrel sulfate, using 20 mmol·L-1 MSA as eluent. A pre-concentration column Dionex CG17 was used to enrich the trace TEAB. After being switched to analytical system, the separation was performed on Dionex ICS3000 using Dionex IonPac CS17 as analytical column, and suppressor was not required. 5 mmol·L-1 MSA containing 35% acetonitrile was used as mobile phase. RESULTS: The RSDs of retention time and peak area were good. The recoveries of TEAB were between 97.8%-103.3%. The calibration curves of analytes were linear in the range between 0.4 and 10.0 μg·mL-1. The limit of detection reached 0.2 μg·mL-1. CONCLUSION: This method can be applied to detect trace kation in pharmaceutical chemicals.

Objective To investigate the protective effect of sodium butyrate on brain injury induced by pneumolysin of infantile rats.Methods Ninety-six normal healthy 1-month-old Spragne-Dawley (SD) rats were randomly divided into three groups,including pneumolysin (PLY) group (n =32),in which rat was injected PLY via external carotid; Normal saline (NS) group (n =32),injected NS via external carotid; sodium butyrate (SB) group (n =32),after injecting PLY,immediately administrated SB via venous.In the injection the 24th h and 48th h,superior vena cava blood was taken,and the animals were sacrificed,and brain tissue samples were prepared.The brain water content (BWC) was recorded by measuring both wet and dry weight,the Evans blue (EB) level was measured by the formamide method.The serum levels of high mobility group protein B1 (HMGB1) and nuclear factor kappa B (NF-κB) were measured by enzyme-linked immunosorbent assay (ELISA).Results In PLY group,brain tissue BWC,EB level,and the blood level of HMGB1 and NF-κB were increased significantly compared with the NS group at each time point,the difference was statistically significant (P ＜ 0.05).These indices were lower in the SB group compared with PLY group,the difference was statistically significant (P ＜ 0.05).The positive correlation was gotten between HMGB1 and NF-κB,BWC,EB levels in the PLY group and SB group (r =0.817 ～0.917,P ＜ 0.05).Conclusions SB has neuroprotective effect in brain injury induced by PLY,which maybe relevant to inhibition of NF-κB activation and suppression of HMGB1 expression.

Objective To investigate whether enteric nervous system(ENS)involve in mediating the effect of short pulse gastric electrical stimulation on c-fos expression in nucleus tractus solitarius (NTS)and hypothalamus.Methods Fifteen Wistar rats were divided into control group,gastric electrical stimulation(GES)group and ENS free group with 5 rats each.A pair of electrodes was implanted on the gastric serosa.In ENS free group,0.5%benzalkonii chloridum was applied on the serosa during the surgery.A set of short pulse GES with frequency of 20 cpm,pulse width of 300 μs and amplitude of 2 mA was applied via the electrodes for 30 rain in the stimulation group and ENS free group.The c-fos expression in NTS/hypothalamus was detected 1 h after the stimulation.Results The number of neuron with c-fos expression was(71.6±7.4)/HP in NTS group and(63.4±10.8)/HP in ENS free group,both were significantly higher than those in control group(36.4±8.6/HP,P＜0.05).The number of neuron with c-fos expression in hypothalamus was higher in GES[(224.2±47.3)/HP]and ENS free groups[(249.1±44.0)/HP]compared with control group[(90.2±47.3)/HP,P＜0.05].There was no significant difference in c-fos expression in NTS/hypothalamus between GES group and ENS free group(P＞0.05).Conclusions Short pulse gastric electrical stimulation significantly increases c-fos expression in NTS/hypothalamus,which suggests that NTS/hypothalamus may participate in mediating the effect of GES on gastric function.This effect may be not mediated by ENS.

Objective To compare the clinical efficacy of multi-target lateral puncture combined with intracranial pressure monitoring in treatment of basal ganglia hypertensive cerebral hemorrhage. Methods Sixty-six patients of basal ganglia hypertensive cerebral hemorrhage, with bleeding volume over 40 ml were divided into experimental group (36 cases) and control group (30 cases) by random digits table method. Patients in experimental group underwent multi-target puncture combined with routine intracerebroventricular treatment of intracranial pressure monitoring,and patients in control group underwent frontotemporal craniotomy and small hematoma decompressive craniotomy. The operation time, length of stay, hematoma evacuation rate, catheter drainage time, total amount of mannitol, Glasgow Coma Scale (GCS) scores 3 days after treatment, complication rate and 3-month Glasgow Outcome Scale (GOS) scores were recorded and compared between two groups. Results The operation time, length of stay, hematoma evacuation rate 1 day after treatment, and total amount of mannitol in experimental group were significantly lower than those in control group: (67.5±8.0) min vs. (109.3±9.6) min, (18.6±4.2) min vs. (23.3±5.9) min, (59.7±9.2)% vs. (80.4±11.6)%, (668.6±83.5) g vs. (1 430.4±107.1) g, P<0.01. The hematoma evacuation rate 3 days after treatment, catheter drainage time and GCS scores 3 days after treatment between two groups had no significant differences (P>0.05). The GOS scores in experimental group: 5 points (9 cases), 4 points (10 cases), 3 points (8 cases), 2 points(5 cases), and 1 point(4 cases). The GOS scores in control group: 5 points (4 cases), 4 points (4 cases), 3 points (7 cases), 2 points (9 cases), and 1 point (6 cases). Long curative effect in experimental group was better than that in control group (Z =2.318, P =0.020). The incidence of intracranial air in experimental group was significantly higher than that in control group: 27.8%(10/36) vs. 3.3%(1/30), P<0.05. Other complications had no significant differences between two groups (P>0.05). Conclusions Multi-target lateral puncture combined with intracranial pressure monitoring in treatment of basal ganglia hypertensive cerebral hemorrhage has more advantages, including less trauma, wide surgical indications, short operation time and hospital stay, less postoperative mannitol, and decreased mortality rate. For older, patients with organ dysfunction, and patients who can not tolerate craniotomy, it is an effective treatment, and worthy of promotion.
