OBJECTIVETo observe the effect of Xingnaojing Injection combined with minimally invasive percutaneous drainage on brain edema and content of serum aquaporin-4 (AQP4) in patients with moderate hypertensive basal ganglia hemorrhage, and discuss the treatment mechanism of Xingnaojing injection combined with minimally invasive percutaneous drainage for cerebral hemorrhage.

METHODForty-two patients with moderate (25-50 mL) hypertensive basal ganglia hemorrhage (< 24 h) were selected and randomly divided into two groups: the observation group (n = 22) and the control group (n = 20). The neurological severity score were evaluated by the NIHSS (national institutes of health stroke scale), the volume of brain edemas were measured by head CT, the serum levels of AQP4 were determined by ELISA method on admission and 1 and 2 weeks after treatment.

RESULTOn admission, there was no significant difference in the scores of NIHSS, the volume of brain edemas and the level of serum AQP4 between the observation group and the control group. At the end of the first week after the treatment, the score of NIHSS of the observation group were lower than that of the control group, with significant different (P < 0.05); the observation group showed reduced volume of brain edemas than that on admission (P < 0.05), whereas the control group the control group showed increased volume of brain edemas than that on admission; the control group displayed increased level of serum AQP4 than that on admission, but without significant difference; the observation group displayed decreased level of serum AQP4 than that on admission (P < 0.05). At the end of the second week after the treatment, the control group showed decreased score of NIHSS than that on admission and at the end of the first week after treatment (P < 0.05). Compared with the control group, the observation group showed a much lower score of NIHSS (P < 0.01), the control group displayed reduced volume of brain edemas than that on admission and at the end of the first week after treatment, but the observation group was even lower than the control group. Both of observation and control groups displayed significantly reduced level of AQP4 (P < 0.05), but the observation group showed a lower AQP4 level than that of the control group (P < 0.05).

CONCLUSIONThe therapy of Xingnaojing injection combined with minimally invasive percutaneous drainage could remarkably reduce brain edema, and promote neural functional recovery, thus could be selected as a therapeutic regimen for patients with moderate hypertensive basal ganglia hemorrhage.

Objective To explorethe expression and distribution of nitric oxide synthase (NOS) and brain-derived neurotrophic factor (BDNF) in the egeball of Chinese alligator, as well as the relationship between them in the eyeball. Methods The homology of amino acid sequence of BDNF or NOS proteinfromhuman, Oryctolaguscuniculus, Xenopuslaevis and Danioreriowas analyzed by bioinformatics. The distribution sites of NOS and BDNF in the alligator's eyeball were detected using HE staining, immunohistochemistry and immunofluorescence, respectively. Results Both the choroid layer and the layer of the retina found the BDNF expressing in the alligator's eyeball. The NOS immunopositive was abundantly expressed in the ganglion cell layer of the retina. The BDNF and NOS were both founded in the ganglion cell layer and the inner boundary layer of the retina. Conclusion BDNF and NOS are expressed in the eyeballs of Chinese alligators, which may be related to the adjustment of visual formation.

Objective To assess the elasticity change of common carotid artery in early stage of atherosclerosis in patients with type 2 diabetes by velocity vector imaging(VVI).Methods Sixty patients with type 2 diabetes were divided into group A(32 cases)and group B(28case)according the vascular complications(including Macroangiopathy and Microangiopathy).Patients without vascular complications belong to group A,others belong to group B.Fifty-eight healthy volunteers were supplied as normal control group.Time to the peak of velocity(VTTP),maximum of velocity(Vmax),maximum of strain(Smax),and maximum of strain rate(SRmax)of six segment(anterolateral wall,anterior wall,anteromedial wall,posteromedial wall,posterior wall,posterolateral wall)were measured,which were supplied by VVI automatic analysis software.Results VTTP,Smax and SRmax had no significant differences in any segments intra-group A,B and control group(P＞0.05).Vmax had significant differences in some segments in control group,group A and group B,Vmax of anterior wall,anterolateral wall and posterolateral wall were higher than those of posterior wall,posteromedial wall and anteromedial wall(P＜0.05).VTTP,Vmax,Smax and SRmax of corresponding segments had significant differences among group A,group B and control group(P＜0.05),control group＞group A＞group B(P＜0.05).Conclusions The change of common carotid elasticity can be detected in early stage of atherosclerosis in patients with type 2 diabetes by VVI.

Objective To investigate the effects in elasticity of anterior tibial artery in new patients with type 2 diabetes caused by medicines of reducing blood sugar. Methods One hundred patients with type 2 diabetes were involved. The patients were divided into control group(50 cases) and case group(50 cases) according the vascular complications (including macroangiopathy and microangiopathy). Maxmum of circumferential strain(CSmax) of anterior tibial artery was acquired through strain and strain rate imaging. Local blood pressure which included local systolic blood pressure(LSBP) and local diastolic blood pressure (LDBP) of anterior tibial artery was measured at the same time. Strain-blood pressure index(SBPI) of anterior tibial artery was calculated, SBPI = CSmax/[(LSBP - LDBP)/LDBP] × 100%. It took six months for each patient to take medicines of reducing blood sugar. Then SBPI of anterior tibial artery was calculated again. Parameters were compared inter- and intra-groups. Results SBPI of anterior tibial artery after therapy was higher than that before therapy in control group( P<0. 05). There was no significant difference between SBPI of anterior tibial artery before therapy and that after therapy in case group( P >0. 05). SBPI of anterior tibial artery in case group was lower than that in control whatever before and after therapy( P < 0. 05). Conclusions The protection of medicines of reducing blood sugar on elasticity of anterior tibial artery in new diabetic patients without vascular complications was better.

Objective To study the value of magnetic resonance vessel wall imaging in assessing the atherosclerotic plaque burden of rabbit model.Methods We built up abdominal atherosclerotic animal model in 30 New Zealand rabbits by high lipid diet combined with abdominal artery denudation.The animals were divided into 3 groups randomly,which were the 1-week group,1-month group and 2-months group.The MRI and histology examination were carried out at relative time points.The correlations of area or thickness of vessel wall by MRI with histology examination were analyzed.Results Among the 30 rabbits,3 died due to anesthesia or surgery,one rabbit model failed because of the thin vessel,and another 3 died of diarrhea or inflammation during the high lipid diet feeding.Eventually,totally 23 rabbits fulfilled the examinations (7 in 1-week group,7 in 1-month group and 9 in 2-months group).The vessel wall area of histology examination grew larger along with the post-surgery duration,from 1.7663 mm2of 1-week group to 2.4371 mm2 of the 1-month group till 3.5978 mm2 of 2-months group,with statistic significant difference among 3 groups (F=5.052,P=0.017).There were strong correlations of area or thickness vessel wall resulted from MRI with histology examination(r=0.688,0.642;P=0.001,0.002).Conclusions High resolution MR vessel wall imaging technique may evaluate and follow up the plaque burden in the early stage of atherosclerosis.

Objective To investigate the clinical value of dynamic glucose monitoring in the middle and late pregnant women with diabetes mellitus,and the related clinical and nursing measures.Methods One hundred admitting cases of the middle and late pregnant women with diabetes mellitus were grouped according to the random number table,50 cases of the control group were treated with finger tip blood glucose monitoring and conventional treatment,50 cases of dynamic blood glucose monitoring and comprehensive clinical and nursing intervention for the observation group.The blood glucose control situation with different time,the incidence of hypoglycemia,the actual control range of the glycosylated hemoglobinblood and the length of hospital stay and so on were evaluated in two groups.Results The incidence of hypoglycemia in the observation group was 6.0％ (3/50),the control group was 24.0％ (12/50),the difference was statistically significant (P ＜ 0.05).In the early morning,after breakfast 2 h,before and after lunch 2 h,before and after dinner 2 h and before bed and other different time,the blood glucose level with the observation group was lower than that in the control group (P ＜ 0.05).At the same time,in the blood glucose effective controlling time,hospitalization time,the observation group was better than the control group (P ＜ 0.05).The blood glucose level and the detection range of the glycosylated hemoglobin were also detected in the safe state for outpatient follow-up after hospital discharge.Conclusions The intervention of dynamic blood glucose monitoring and comprehensive clinical and nursing measures in middle and late pregnant women with diabetes mellitus is conducive to control blood glucose level timely and accurately and to improve their prognosis.It is the key to the success of the future obstetric prevention and diagnosis and treatment of the disease,and is recommended clinical popularization.

Objective To investigate the efficacy and safety of citrate anticoagulation for continuous renal placement therapy (CRRT) in patients at high risk of bleeding. Methods Forty-seven patients who needed to CRRT and were admitted into the department of critical care medicine from January 2015 to October 2016 were enrolled in this study. According to the patient′s actual condition, they were divided into citrate groups (24 cases) and saline group (23 cases). Patients in saline group were given saline wash. The efficacy and safety were compared between the two groups. The filter lifetime, after treatment the activated partial thromboplastin time (APTT), hemoglobin (Hb), blood gas indexes were compared between the two groups. Results The citrate group used 76 filters while the 0.9% sodium chloride group used 87 filters. The average filter lifetime in citrate group was (22.4 ± 12.7) h which was longer than (8.6±3.3) h in 0.9%sodium chloride group (t=9.79, P<0.01). The incidence of coagulation in extracorporeal circulation was 3.9%(3/76) which was lower than 16.1%(14/87) in 0.9%sodium chloride group(χ2=5.20, P<0.05). Conclusions Regional citrate anticoagulation is a safe and effective option for CRRT in patients at high risk of bleeding.
