Objective To compare the clinical efficacy and angiographic outcomes of balloon dilation angioplasty,balloon-expandable stent implantation and self-expanding stent implantation in the treatment of intracranial arterial stenosis.Methods The patients with intracranial arterial stenosis who met the indications of surgical intervention treated with balloon dilatation angioplasty and stent placement were selected from Nanjing Stroke Registry Program.According to the different interventional procedures,the patients were divided into the balloon expandable stenting goup,the self-expanding stents group and the balloon dilatation angioplasty group.The success rate of surgery,the perioperative complication rate and the significant residual stenosis rate were compared among the three groups.The clinical and angiographic assessments were performed through 1-,3-,6-,12- and 24-month regular outpatient or inpatient follow-up after procedure.The incidences of ischemic stroke and/or death and restenosis within 2 years were compared.Multivariate Cox proportional hazards analysis was used to analyze the risk factors for recurrent ischemic stroke and/or death and restenosis.Results A total of 183 patients with 192 stenoses performed balloon dilatation angioplasty or stenting,in which 92 were in the balloon expandable stenting goup,42 were in the self-expanding stents goup and 49 in the balloon dilatation angioplasty group.Their preoperative stenosis rates were 80.2 ±12.8％ 、76.3 ± 11.9％ and 89.7 ± 10.2％,respectively (F =15.863,P =0.000).There were no significant differences in other baseline data.The success rates of surgery in the balloon expandable stenting group,self-expanding stents group and balloon dilatation angioplasty group were 96.7％,95.2％ and 91.8％,respectively (x2 =1.646,P =0.439).The perioperative complication rates were 6.5％,14.3％ and 10.2％,respectively (Fisher exact test,P=0.334).The imaging follow-up showed that the restenosis rate in the balloon dilatation angioplasty group was 48.5％.Although it was high than 27.7％ in the balloon expandable stenting group and 34.8％ in the self-expanding stents group,there were no significant differences (x2 =4.176,P =0.124).Multivariate Cox proportional hazards analysis showed that balloon dilatation angioplasty was an independent risk factor for restenosis after procedure (hazard ratio 2.490,95％ confidence interval 1.247- 4.969,P=0.010).Conclusions Compared to the balloon expandable stenting,the balloon dilatation angioplasty is more likely to have restenosis,but it is not associated with the risks of postoperative recurrent ischemic stroke and/or death.

Vascular smooth muscle cell (VSMC) proliferation and migation play important roles in the occurrence and development of atherosclerosis and restenosis after intravascular stenting.The studies in recent years have shown that kallikrein-kinin system (KKS) is closely correlated with VSMC proliferation and migration in cytokines and transduction pathways.Therefore,investigating the roles of KKS in the VSMC proliferation and migation process has great significance in clinical prevention and treatment of atherosclerosis and restenosis after intravascular stenting.

Objective: To observe the clinical efficacy and safety of early acupuncture in the treatment of acute ischemic stroke. Methods: In clinical randomized controlled trial, 90 subjects were divided into drug group and acupuncture group, 45 cases in each group. The neurological deficit score, Bathel index and some blood laboratory indexes were detected before and after treatment in both groups. Results: In acute stage, there were striking differences in the neurological deficit score and activities of daily living (ADL) between before and after treatments in acupuncture group (P<0.01), and between acupuncture group and drug group (P<0.01); but there was no difference in blood lipid and theology between two groups. Conclusion: Acupuncture is rather safe in the early treatment of acute ischemic stroke, and improvement of disability and the patients' quality of life.

Objective To explore the effect of bacillus calmette-guerin (BCG)intervention on expression of costimulatory molecules of B7-CD28/CD152 and T lymphocyte apoptosis in asthmatic mouse.Methods Twenty-seven mice were randomly divided into:asthma model group,BCG treatment group and normal control group.The mice were sensitized by ovalbumin(OVA) and 100 g/L Al(OH)3 with intraperitoneal injection,challenged with atomization inhalation,then reproduced the asthmatic models.The BCG treatment group were treated with BCG(0.025 mg,merely) subcutaneous injection 3 times before sensitization(5,3,1 day).The normal control group were treated with 9 g/L saline water taking place of OVA and Al(OH)3.CD28,CD152,CD80 and CD86 were analyzed by flow cytometry in splenic lymphocyte suspension.T lymphocyte was cultivated from peripheral blood mononuclear cell.The apoptosis ratio of T lymphocyte was counted by Comet Assay.SPSS 10.0 software was applied to analyze data.Results Contrasting asthma model group with normal control group,CD28 was up regulated(t=3.94 P0.05),CD86 was up regulated(t=2.68 P0.05).Contrasting BCG treatment group with asthma model group,T lymphocyte apoptosis rate was higher(t=3.15 P

Background Oxidative stress is thought to be responsible to diabetes-complicated cataract.Our previous study demonstrated that as an iron chelator,deferiprone can protect lens from oxidative damage.Objective This further study aimed to investigate the role of deferiprone on the formation of diabetic-complicated cataract.Methods Forty 6-week-old Wistar rats were included in the study and randomized into 4 groups.Eight of them were used as the normal control group.Diabetes mellitus animal models were established in 22 rats by the carbonhydratediet and fat diet and the intraperitoneal injection of 40 mg/kg streptozocin (STZ).The deferiprone of 50 mg and 100 mg were intragastrically given in 8 model rats respectively after 3 days once a day for 8 weeks.The opacification of lenses was examined under the slit lamp weekly after treatment.The animals were sacrificed and the lenses were obtained at the eighth week of deferiprone injection.The concentrations of water-soluble protein ( WSP),urine-soluble protein (USP) and alkali-soluble protein (ASP) in rat lens suspension were detected by Bradford method.The super oxide dimutese (SOD),malondialdehyde (MDA) and glutathione (GSH) were determined spectrometically using xanthine oxidase,thiobarbituric acid,dithio bis-nitrobenzoic acid.Results No evidently differences were found in the content of the WSP,USP and ASP among the these groups( F=1.73,0.18,0.09,P＞0.05).The contents of MDA in 50 mg deferiprone group and 100 mg deferiprone group were ( 1.05 ± 0.10 ) mmol/g and ( 1.05 ± 0.22 ) mmol/g respectively,showing a significant decline in comparison with diabetic model group (P＜0.05).The SOD and GSH contents in lens were (321.29±16.57) U/mg,(322.07±22.16) U/mg and (7.83±0.65 ) mg/g,(7.70±0.77 ) mg/g respectively in 50 mg deferiprone group and 100 mg deferiprone group and were considerably elevated in comparison with ( 298.70± 14.69 ) U/mg and ( 5.47 ± 1.01 ) mg/g of diabetic model groups ( P＜0.05 ).No significant differences were found in the indexes mentioned above between 50 mg and 100 mg deferiprone groups(P＞0.05).Conclusions Deferiprone can reduce oxidative stress and improve the energy metabolism of the lens in diabetic rats.

Objective To investigate the prevalence of clonorchiasis among residents of Huachuan Country,Heilongjiang Province and to provide a basis for development of control strategies.Methods From 2011 to 2012,cluster random sampling was performed to survey the incidence of clonorchiasis in Huachuan Country.Fecal specimens were collected and examined the clonorchis sinensis eggs by Kato-Katz method.A questionnaire survey was conducted to collect related information such as age,gender,occupation and eating habits.The infection characteristic was analyzed.Results Totally 884 patients with clonorchiasis were found among 2248 residents,and the infection rate was 39.32％.The infection rate in male[47.15％(611/1296)] was significantly higher than females [28.68％(273/952),x2 =34.55,P ＜ 0.01].The infection rate increased with age,which was higher in the 20-69 years old people,with the highest infection rate in the 50-59 years old groups[45.34％ (219/483)].Of the occupational distribution,farmers had the highest infection rate [47.24％ (420/889)],followed by cadres and staffs[38.38％(190/495)].Of residents with fresh fish eating history,the prevalence of clonorchiasis was 53.38％(150/281).Conclusions The prevalence of clonorchiasis is still high in Huachuan County.To reduce the prevalence of clonorchiasis,comprehensive prevention measures,health education and group chemotherapy should be carried out.

OBJECTIVE: To investigate the characteristics of adductor spasmodic dysphonia phonatory break in mandarin Chinese and select the stimuli phrases. METHOD: Thirty-eight patients with adductor spasmodic dysphonia were involved in this study. Standard phrase " fù mŭ xīn" and a speech corpus in mandarin Chinese with 229 syllables covering all vowel and constant of mandarin Chinese were selected. Every patient read the phrases above twice in normal speed and comfortable voice. Two auditory perpetual speech pathologists marked phonatory break syllables respectively. The frequency of phonatory break syllables and their located phrases were calculated, rated and described. The phrases including the most phonatory break syllables were selected as stimuli phrases, the phonatory break frequency of which was also higher than that of standard phrase "fù mŭ xīn". RESULT: Phonatory break happened in the reading of all patients. The average number of phonatory break syllables was 14 (3-33). Phonatroy break occurred when saying 177 (77.3%) syllables in the speech corpus. The syllables "guŏ, rén, zāng, diàn, chē, gè, guăn, a, bā, ne, de" broke in 23.1%-41.0% patients. These syllables belonged to the phrases "pĭng guŏ, huŏ chē, shì de, nĭ shì gè hăo rén, wŏ mén shì yŏu zŏng shì bă qĭn shì nong dé hĕn zāng, wŏ mén nà biān yŏu wăng qiú yùn dong chăng, cān gŭan, jiŭ bā hé yī gè miàn bāo dìan, tā shì duō me kāng kăi a,wŏ yīng gāi zài xìn lĭ xiĕ yī xiē shén mē ne?". Thirty-seven patients (97.3%) had phonatory break in above mentioned words. Ratios of these words phonatory break also were more than "fù mŭ xīn". CONCLUSION Adductor spasmodic dysphonic patients exhibited different degrees of phonatory break in mandarine Chinese. The phrases" shì de, pĭng guŏ, huŏ chē, nĭ shì gè hăo rén, wŏ mén nà biān yŏu wăng qiú yùn dong chăng, cān gŭan, jiŭ bā hé yī gè miàn bāo dìan, tā shì duō me kāng kăi a" were recommended as stimuli phrases for adductor spasmodic dysphonia evaluation.

Objective To investigate the therapeutic efficacy and safety of endoscopic resection of giant gastric stromal tumors without explicit evidence of metastases.Methods A total of 12 giant gastric stromal tumors with no evidence of metastases diagnosed by endoscopic ultrasound (EUS) and computed tomography (CT) scan were managed by endoscopic resection.Operation time,blood loss and the incidence rate of perforation were recorded respectively.The diagnoses of tissue specimens were made by pathological examination and immunohistochemistry.In order to assess local recurrence and distant metastases,endoscopy and endoscopic ultrasound follow-up examinations were performed routinely at 2,6 and 12 months,and the whole abdominal CT scan was also performed at 12 months after operation.Results Endoscopic resections were successfully performed in 10 of 12 cases (83.3％),among which,6 underwent endoscopic submucosal excavation (ESE) without unexpected perforation and 4 endoscopic full-thickness resection (EFR)with intentional perforation.The rate of intentional perforation was 33.3％ (4/12),and all the perforations could be sealed by endoscopic methods.The blood losses were all more than 100 ml,which could be controlled by argon plasma coagulation,electrocoagulation or hemostatic clips.In the 10 encapsulated tumors,8 could be smoothly removed from esophagus,whose long diameter of the minimum cross section was less than 3.5 cm,however,2 tumors whose diameters were larger than 3.5 cm were taken out after segmentation.In the 10 tissue samples,9 were confirmed as low risk GIST,1 larger than 5 cm was pathologically confirmed as high risk GIST.During 1-year follow-up,no local recurrence or peritoneal metastasis was found.2 tumors,larger than 5.0 cm,could not be removed by endoscopic methods due to uncontrolled bleeding.The rate of uncontrolled bleeding was 16.7％ (2/12).The patients were transferred to surgery,and pathologically confirmed as having high risk GIST.Conclusion For low-risk giant gastric stromal tumors whose diameters were less than 5cm without evidence of metastases,endoscopic resection is considered as a safe and effective procedure.Tumors with long diameter of the minimum cross section less than 3.5 cm are more suitable for endoscopic resection,which can be smoothly taken out through cardia.However,for high-risk GIST larger than 5.0 cm,the rate of uncontrolled bleeding is high,so endoscopic resection should be adopted with discretion.
