Objeetive To explore the correlative factors of early progressive motor deficits in cerebral infarction of moderately size in basal ganglia and the relationship between motor deficit progression and the stem lesion of middle cerebral artery.Methods One hundred and fifty patients with single acute infarction located in white matter of basal ganglia region were recruited in this study retrospectively.All patients were performed brain and neck MRI and magnetic resonance angiography (MRA) within 72 h after onset.They were divided into two groups based on the maximal diameter of infarction on diffuse weighing imaging(DWI):moderate size infarction group(75 patients,maximal diameter of infarction from 1.5 cm to 3.0 cm) and lacunar infarction group(75 patients,maximal diameter of infarction lower than 1.5 cm).The scores of dynamic National Institutes of Health Stroke Scale(NIHSS) in 7 d after the admission and multiple Logistic regression analysis were used and the risk factors of the early progressive motor deficits were analyzed.Results The rate of early progressive motor deficits in moderate size infarction group was significant higher than that in lacunar infarction group [32.0 ％ (24/75) vs.8.0 ％ (6f75)] (P ＜ 0.05).The multiple Logistic regression analysis showed that elevated systolic blood pressure on admission was the independent risk factor for early progressive motor deficits (P =0.016).The rate of stem lesion of middle cerebral artery in moderate size infarction group was significantly higher than that in lacunar infarction group [41.3 ％ (31/75) vs.9.3 ％ (7/75)] (P ＜ 0.01).Conclusions Patients with acute single infarction located in white matter of basal ganglia and with the diameter of 1.5-3.0 cm are more prone to early progressive motor deficits and elevated systolic blood pressure on admission is the most significantly independent factor.The pathogenic mechanism may be associated with the stem lesion of middle cerebral artery.

Ureaplasma urealyticum(UU)is one of the most common pathogen in childbearing age women.The proportion of neonate especially premature baby infected with UU is increasing yearly.UU infaction is related with premature labour,low birth weight,bronchopulmonary dysplasia,chronic lung disease,respiratory distress syndrome and other perinatal diseases by promoted the expression of inflammatory cytokines,increasing the inflammatory response and interfering inflammation clear.There still has controversial point to treat perinatal diseases caused by UU infection by erythromycin,azithromycin,pulmonary surfactant,steroid.

Objective To investigate the relationship between white-matter hyperintensities (WMHs) and hemorrhagic transformation and neurological outcome at 3 months after recombinant tissue plasminogen activator (rt-PA) treatment in patients with acute ischemic stroke.Methods The chnical data of 132 patients with acute ischemic stroke who had received intravenous rt-PA therapy were retrospectively reviewed.The severity of WMHs according to the modified Schelten scale was assessed.Hemorrhagic transformation included hemorrhagic infarct (HI) and cerebral parenchymal hemorrhage (PH).Hemorrhagic transformation after thrombolytic therapy and clinical neurological outcome based on modified Rankin scale (mRS) at 3 months was also analyzed.Favorable neurological outcome as mRS 0-1 score and unfavorable neurological outcome as mRS 2-6 scores was defined.Results Hemorrhagic transformation was found in 26 patients (19.7％,26/132) among 132 patients receiving intravenous rt-PA treatment.Seventeen patients were HI type and 9 patients were PH type.Multiple Logistic regression analysis showed that baseline American National Institute of Health Stroke Scale (NIHSS) score,diastolic pressure,WMHs score was not correlated with HI type hemorrhagic transformation (P ＞ 0.05) ; and WMHs score was not correlated with PH type hemorrhagic transformation (P ＞0.05),but baseline NIHSS score,diastolic pressure was the independent risk factor of PH type hemorrhagic transformation (P ＜ 0.05).Dicho-Logistic regression analysis showed that WMHs score was the independent risk factor of unfavorable neurological outcome (OR =1.136,95％ CI 1.037-1.245,P =0.008).Conclusion Severe WMHs are not associated with hemorrhagic transformation but independently associated with unfavorable neurological outcome after thrombolytic therapy in patients with acute ischemic stroke.

Objective To study AngⅡ induced apoptosis of HUVECs and to observe the protective effect of serum contained huangqi on endothelial cell.Methods ECV-304 cells were randomly divided into control group,AngⅡgroup and huangqi group.In the control group,cells were cultured for 18 h,and the concentration of AngⅡ were 0 mol/L,1×10-6 mol/L,1×10-5 mol/L and 1×10-4 mol/L.The cell proliferation was measured by MTT assay.Electron microscope was used to observe the change of HU-VECs.Ultrastructure of HUVECs induced by AngⅡ was observed by electron microscope.In the huangqi group,serum contained huangqi of different concentration were added into the medium and cultured for 24 h,then AngⅡ of 1×10-4 mol/L was included and cultured for 18 h,and the apoptosis ratio induced by AngⅡwas measured by flow cytometry.Results AngⅡof different con-centration could all significantly inhibit HUVECs proliferation.AngⅡof different concentration could all induce endothelial cell ap-optosis.HUVECs apoptosis was observed by electron microscope.HUVECs apoptosis induced by AngⅡcould be inhibited by ser-um contained huangqi.Conclusion Serum contained huangqi could protect endothelial cells.

AIM:To investigate how to design personalized cataract surgery programs to achieve surgical correction of preoperative corneal astigmatism with surgical astigmatism under the guidance of corneal topography, improve postoperative visual quality and reduce the cost of treatment.
METHODS: Totally 202 cases ( 226 eyes ) cataract patients were divided into randomized treatment group and individualized treatment group. According to the method and location of the incision, randomized treatment group were divided into 8 groups. Surgical astigmatism after different incision were calculated with the use of preoperative and postoperative corneal astigmatism through vector analysis method. Individualized treatment groups were designed personably for surgical method with reference of every surgically induced astigmatism, the surgical method chooses the type of surgical incision based on close link between preoperative corneal astigmatism and surgically induced astigmatism, and the incision was located in the steep meridian. The postoperative corneal astigmatism of individualized treatment group was observed.
RESULTS: Postoperative corneal astigmatism of individualized treatment group were lower than that of 3.0mm clear corneal tunnel incision in the randomized treatment group, there were statistically significance difference, while with 3. 0mm sclera tunnel incision group there were no statistically significance difference. After 55. 8% of patients with the use of individualized surgical plan could undergo the operation of extracapsular cataract extraction with relatively low cost and rigid intraocular lens implantation, the per capita cost of treatment could be reduced.
CONCLUSION: Personalized cataract surgery programs are designed to achieve surgical correction of preoperative corneal astigmatism under the use of corneal topography, improve postoperative visual quality and reduce the cost of treatment.

OBJECTIVETo assess the effectiveness and safety on post-stroke dysphagia in chronic stage treated with magnetic-ball sticking therapy at the auricular points.

METHODSNinety cases of post-apoplexy dysphagia in chronic stage were randomized into an auricular points group and an acupuncture group. In the auricular points group, the magnetic-ball sticking therapy was applied to subcortex (pizhixia, AT4), brainstem (naogan, AT(3,4i)), mouth (kou, CO1), cheek (mianjia, LO(5,6i)), tongue (she, LO2) and throat (yanhou, TG3) on one ear each time, and were changed on the other ear once every 3 days. In the acupucnture group, acupuncture was applied to Feng-chi (GB 20), Yifeng (TE 17), Shanglianquan (Extra), Jinjin (EX-HN 12), Yuye (EX-HN 13), Shuigou (GV 26) and Tongli (TH 5), etc. The needles were retained for 30 min in each treatment. The treatment was gi-yen once a day in the two groups and the treatment of 6 days made one session. There was 1 day at an interval among the sessions. Totally, 3 sessions of treatment were required. The video fluoroscopic swallowing study (VFSS) was performed for 4 kinds of food with different properties and shapes in each patient. The main indices were Rosenbek penetration-aspiration score, oral-retaining score and throat-retaining score. The efficacy, and the incidences of aspiration pneumonia and malnutrition were compared between the two groups. The nutrition indices were compared before and after treatment between the two groups, such as the skinfold thickness of triceps brachii muscle, serum albumin and peralbumin.

RESULTSIn 21 days of treatment, in the auricular points group, the 1 mL liquid loversol Rosenbek penetration-aspiration score (1.51 +/- 0.69), oral-retaining score (1.17 +/- 0.38) and throat-retaining score (1.30 +/- 0.66) were all lower than those (2.51 +/- 0.67, 1.63 +/- 0.72, 1.67 +/- 0.7) in the acupuncture group separately. The 10 mL liquid loversol Rosenbek penetration-aspiration score (2.27 +/- 0.65), oral-retaining score (1.60 +/- 0.50) and throat-retaining score (1.49 +/- 0.51) were all lower than those (4.19 +/- 0.73, 2.30 +/- 0.51, 2.41 +/- 0.50) in the acupuncture group separately. The 10 mL paste loversol Rosenbek penetration-aspiration score (1.68 +/- 0.81), oral-retaining score (1.11 +/- 0.31) and throat-retaining score (1.10 +/- 0.31) were all lower than those (3.91 +/- 0.68, 1.63 +/- 0.76, 1.60 +/- 0.76) in the acupuncture group separately. The 1/4 cake-form loversol Rosenbek penetration-aspiration score (2.60 +/- 0.65), oral-retaining score (1.40 +/- 0.50) and throat-retaining score (1.74 +/- 0.49) were all lower than those (4.14 +/- 1.10, 2.40 +/- 0.73, 2.30 +/- 0.83) in the acupuncture group separately. The incidence of aspiration pneumonia was 14.9% (7/47) in the auricular points group, which was lower than 55.0% (22/40) in the acupuncture group (P < 0.01). The incidence of malnutrition was 8. 5% (4/47) in the auricular points group, which was lower than 50.0% (20/40) in the acupuncture group (P < 0.01). In 21 days of treatment, the results of the skinfold thickness of triceps brachii muscle and serum albumin in the auricular points group were better than those in the acupuncture group (both P < 0.05).

CONCLUSIONThe magnetic-ball sticking therapy at auricular points achieves the definite efficacy on post-stoke dysphagia in chronic stage and decreases the incidences of aspiration pneumonia and malnutrition. The efficacy of this therapy is better than acupuncture.

This study is to investigate the protective effect of rosiglitazone (RSG) against learning and memory impairment of APP/PS1/tau transgenic mice. AD mice model was replicated by using 6-month APP/PS1/tau transgenic mice. The learning and memory ability of mice was evaluated by Morris water maze and Western blotting assays was applied to measure the phosphorylation and O-glycosylation of Tau and neurofilaments (NFs) protein. The results demonstrated that RSG could reverse the learning and memory deficits of 3 x Tg mice significantly. It was also found that RSG could suppress the hyperphosphorylation of Tau and NFs protein levels and increase the glycosylation expression of Tau and NFs proteins in 3 x Tg mice brain. Together, RSG ameliorates cognitive impairments of 3 x Tg mice via the alleviation of the hyperphosphorylated Tau and NFs proteins burden in the brain.

OBJECTIVETo observe the efficacy and safety of acupuncture therapy on moderate and severe allergic rhinitis via the comparison evaluation of western medicine.

METHODSSixty cases of moderate and severe allergic rhinitis were divided into an acupuncture group (30 cases) and a western medicine group (30 cases). In the acupuncture group, the main acupoints included Yingxiang (LI 20), Shangxing (GV 23), Fengchi (GB 20), Quchi (LI 11), Xuehai (SP 10), Feishu (BL 13), Geshu (BL 17), Pishu (BL 20), etc. The supplementary points were selected according to syndrome differentiation. In the western medicine group, budesonide nasal spray and cetirizine tablets were prescribed. All the cases were treated for 8 weeks in the two groups. Separately, before treatment, in 4 weeks and 8 weeks of treatment, the scores of clinical symptoms and physical signs were observed and the clinical efficacy and safety were compared between the two groups.

RESULTSIn 4 weeks and 8 weeks of treatment, the scores of symptoms such as sneezing, nasal discharge, nasal obstruction, nasal itching, eye itching and turbinate hypertrophy, the score of physical signs and total score were all reduced apparently as compared with those before treatment (all P<0. 05). The differences were not significant between the acupuncture group and the western medicine group (all P>0. 05). The total effective rates were 90. 0% (27/30) and 93. 4% (28/30) in the acupuncture group after 4 and 8 weeks of treatment, and were 76. 6% (23/30) and 80. 0% (24/30) in the western medicine group separately, without significant difference in comparison (all P>0. 05).

CONCLUSIONAcupuncture achieves the similar efficacy on moderate and severe allergic rhinitis as western medicine. It is the safe therapy and has no apparent adverse reactions.
