Objective To evaluate the risk factors for cerebral infarction (CI) resulting from transient ischemic attack (TIA).Methods The clinical data of 133 patients with TIA were evaluated.The condition of CI happening was recorded.Seizure frequency,seizure duration,onset to treatment time,the number of seizure before treatment time,blood pressure,fasting blood glucose,total cholesterol,triglyceride and other factors were collected.The clinical data of TIA with CI and without CI were evaluated.Results Among the 133 patients,there were 48 patients suffering from CI (36.09％).Among 108 patients with TIA in the anterior circulation system,there were 39 patients (36.11％) suffering from CI.Among 20 patients with TIA in the posterior circulation system,there were 7 patients (35.00％) suffering from CI.There was no significant difference in the rate of CI between TIA in the anterior circulation system and TIA in the posterior circulation system (P ＞ 0.05).Among 5 patients with TIA in both the anterior and posterior circulation systems,there were 2 patients suffering from CI.In patients of TIA with seizure frequency ＞ 3 times/d,seizure duration ＞ 30 min,onset to treatment time ＞ 24 h or the number of seizure before treatment ＞5 times,the incidence of CI was significantly higher,and the difference was statistically significant (P ＜ 0.05 or ＜0.01).The onset to treatment time,systolic pressure,diastolic pressure,fasting blood glucose,total cholesterol and triglyceride levels in TIA with CI were significantly higher than those in TIA without CI (P＜0.05).Conclusion There is highly danger for patients to develop CI if patients with TIA has longer seizure duration,much more seizure frequency,longer onset to treatment time,especially those accompany with high blood pressure,hyperglycaemia and hyperlipoidemia.

Objective To analyze the proportion of HPV infection among the patients in the gynecology and obstetrics department and urology surgery department of our hospital,distribution of HPV high risk and low risk subtypes and distribution characteristics of high risk HPV predominant subtypes in various age groups,and to understand the HPV infection situation in this area to provide reference for the prevention of cervical cancer and vaccine development aiming at this area.Methods The cervical exfoliated cells in 889 female patients in our hospital during 2014-2015 were detected by PCR reverse spot hybrid technology,26 HPV subtypes were detected,including 17 high-risk subtypes and 9 low-risk subtypes.Results Among 889 cells samples,168 cases of HPV positive were detected with the positive rate of 18.9%,which was dominated by single infection,148 cases of high-risk subtypes were detected,accounting for 84.5% of the total number of positive cases.24 kinds of HPV subtypes were detected.High risk subtype HPV45 and low risk subtype HPV57 were not detected.The top HPV high-risk subtypes in the detection rates were HPV52,HPV16 and HPV58,in young and middle-age women,HPV16 and HPV52 were predominant infection subtype,accounting for 84.5% of total positive cases.Women >60 years old were mainly infected by HPV58.Conclusion Different subtypes of vaccine can be developed and adopted according to these study results and by aiming at different ages for preventing and treating cervical cancer and increasing the female health level.

Pulse waves contain abundant physiological and pathological information of human body. Research of the relationship between pulse wave and human cardiovascular physiological parameters can not only help clinical diagnosis and treatment of cardiovascular diseases, but also contribute to develop many new medical instruments. Based on the traditional double elastic cavity model, the human cardiovascular system was established by using the electric network model in this paper. The change of wall pressure and blood flow in artery was simulated. And the influence of the peripheral resistance and vessel compliance to the distribution of blood flow in artery was analyzed. The simulation results were compared with the clinical monitoring results to predict the physiological and pathological state of human body. The result showed that the simulation waveform of arterial wall pressure and blood flow was stabile after the second cardiac cycle. With the increasing of peripheral resistance, the systolic blood pressure of artery increased, the diastolic blood pressure had no significant change, and the pulse pressure of artery increased gradually. With the decreasing of vessel compliance, the vasoactivity became worse and the pulse pressure increased correspondingly. The simulation results were consistent with the clinical monitoring results. The increasing of peripheral resistance and decreasing of vascular compliance indicated that the incidence of hypertension and atherosclerosis was increased.

Objective To investigate the effects of different doses of dexmedetomidine(Dex) on rabbit sinus node and atrioventricular node.Methods A total of 24 healthy male rabbits weighing 1.5-2.8 kg,were divided into 3 groups randomly according to random number table (n =8).Group C (control),critical dosage of Dex causing sinus bradycardia D1 (loading dose of Dex was 10 μg/kg, continual pumping dose was 5 μg · kg-1 · h-1 ),six times of critical dosage of Dex causing sinus bradycardia D2 (loading dose of Dex was 60 μg/kg,continual pumping dose was 30 μg·kg-1 ·h-1 ). Rabbits were anesthetized,the right femoral artery was separated and catheterized followed by real-time monitoring of arterial blood pressure.Right external jugular vein was searched and separated,bi-polar stimulating electrode were inserted to the junction of superior vena cava and right atrium,the index of sinus node and atrioventricular node were observed by means of programmed stimulation.Si-nus node recovery time (SNRT),corrected sinus node recovery time (CSNRT),total recovery time (TRT),and atrioventricular node 2∶1 point were recorded before Dex infusion (T0 ),1 5-20 min after infusion of Dex (T1 )and 50-60 min after perfusion of Dex (T2 ).Results SNRT,CSNRT,TRT and 2∶1 point had no statistical significance.Compared with T0 ,SNRT,CSNRT and CSNRT were signifi-cantly prolonged at T1 and T2 .2∶1 point in group D1 and D2 was shortened obviously at T1 than that at T2 (P <0.05).SNRT,CSNRT and TRT of group D1 at T2 were significantly prolonged,2∶1 piont was shortened compared with T1 (P <0.05).SNRT,CSNRT and TRT of group D1 and D2 were pro-longed both at T1 and T2 than those of group C.2∶1 point was shortened in group D1 and D2 at T1 than that in group C (P <0.05).Compared with group D1,SNRT,CSNRT and TRT of group D2 at T1 and T2 were prolonged,2∶1 point was shortened obviously (P <0.05).Conclusion Load capacity of 10 μg/kg Dex apparently inhibits the function of rabbit sinus node and atrioventricular node,which is partially recovered within a short time (≤ 1 h).The inhibiting effect is more continously and re-markably in load capacity of 60 μg/kg Dex.

Objective To investigate the application effect of nasal gastrointestinal double lumen catheter tube placement with air insufflation in mechanically ventilated patients with intra-abdominal hypertension.Methods A total of 20 patients with intra-abdominal hypertension were randomly divided into control group and observation group (n=10 in each group).Patients in control group received indwelling nasogastric tube for decompression and indwelling nasal intestine tube by air insufflation for enteral nutrition support .Patients in observation group received the dual lumen gastrointestinal tube for decompression and enteral nutrition support.The time required for catheterization,changes in intra-abdominal pressure before and after air insufflation,catheter success rate at one attempt,pain scores of patients to catheter operation, duration of decompression,enteral nutrition start time and the duration of mechanical ventilation were compared between two groups.Results The time required for catheterization,catheter air insufflation volume in observation group were significantly lower than those in control group (P <0.01);pain scores of patients to catheter operation were significantly lower in observation group than those in control group (P <0.01);There was no significantly difference in once catheter success rate,changes in intra-abdominal pressure before and after catheterization,abdominal high pressure relief time ,enteral feeding start time, and duration of mechanical ventilation between the two groups (P >0.05 ).Conclusions The technique of air insufflation has higher success rate for Indwelling nasal intestine tube in mechanically ventilated patients with intra-abdominal hypertension,and this method is safe and reliable,dual lumen gastrointestinal tube can improve patients'comfort,shorter catheterization time and reduce catheter air insufflation volume.

Objective To analyze the outcomes of clinical management and rehabilitation interventions for earthquake victims with spinal cord injury. Methods Comprehensive rehabilitation intervention was conducted for 3 to 4 months with 51 earthquake victims with spinal cord injuries. The study involved their physical examination and on site interviews during hospitalization, and follow-up by telephone. Etiology, severity, complications and outcomes of rehabilitation and clinical management were analyzed.

There were 22 complete injuries and 29 incomplete. After 4 months of training, 76.5% of the wounded reached wheelchair independence, 78.4% ambulated with an orthosis and 88.2% were partially independent in the activities of daily living.Conclusions The comprehensive rehabilitation intervention allowed most of the victims to resume an independent life. Their long-term care remains a challenge.

Objective To investigate the effects of butylphthalide soft capsules on cognitive function and daily living ability in patients with Parkinson's disease dementia(PDD). Methods From January 2016 to January 2017, 90 patients with PDD in the First People's Hospital of Wenling were divided into control group and study group by random number table method,with 45 cases in each group. The patients in the two groups were treated with conventional symptomatic treatment, and the control group was treated with donepezil, the study group was treated with butylphthalide soft capsules on this basis. The treatment time was 12 weeks. The clinical efficacies of the two groups were compared. Before treatment and 12 weeks after treatment,the cognitive functions of patients were assessed by Montreal cognitive assessment scale (MoCA) and mini - mental state examination (MMSE),and the daily living abilities of patients were assessed by Barthel index scale. Results The total effective rate of the study group was 93. 33％ ,which was higher than 75. 56％ of the control group (χ2 = 5. 414,P < 0. 05). 12 weeks after treatment,the scores of MoCA and MMSE scales in the two groups were (20. 54 ±2. 53)points,(18. 95 ± 2. 63)points,(23. 53 ± 2. 87)points,(22. 53 ± 2. 62)points,respectively,which were significantly higher than those before treatment[(16. 78 ±2. 34)points,(16. 03 ± 2. 24)points,(16. 23 ± 2. 78)points,(15. 23 ± 2. 34)points](t = 2. 863,2. 735,3. 062,3. 178,all P < 0. 05),and the scores of MoCA and MMSE scales in the study group were higher than those in the control group (t = 2. 798, 2. 753,all P < 0. 05). 12 weeks after treatment,the Barthel scores of the two groups were (64. 43 ± 5. 89) points, (76. 33 ± 5. 23 ) points, respectively, which were significantly higher than those before treatment [( 59. 34 ± 4. 83)points,(58. 26 ± 6. 65)points](t = 2. 916,3. 203,all P < 0. 05),and the Barthel score in the study group was higher than that in the control group (t = 2. 835,P < 0. 05). The incidence rate of adverse reaction in the control group was 6. 67％ ,which in the study group was 8. 89％ ,there was no statistically significant difference between the two groups (χ2 = 0. 155,P > 0. 05). Conclusion Butylphthalide soft capsules can significantly improve the cognitive function and daily living ability of patients with PDD,which is suitable for clinical application and promotion.

Objective To observe the changes of serum ferritin and 25-(OH) vitamin D3 in patients with diabetic cranial neuropathy.Methods There were 50 patients without diabetic Cranial neuropathy,46 patients with diabetic cranial neuropathy,and 40 cases of normal control group.The changes of serum ferritin and 25-hydroxy vitamin D3 were observed in each group.The correlation between two indexes and the correlation with diabetic cranial neuropathy were analzyzed.Results The serum ferritin levels in diabetic group and diabetic neuropathy group were significantly higher than those in normal control group (P ＜ 0.01),and its level in patients with diabetic cranial neuropathy [(687.54 ± 65.38)ng/ml] was significantly higher than that of patients without diabetic cranial neuropathy [(497.28 ± 46.39) ng/ml,P ＜0.01].The serum 25-(OH) vitamin D3 levels in the diabetic group and diabetic neuropathy group were lower than those in the control group (P ＜ 0.01),and its level in patients with diabetic cranial neuropathy [(26.45 ± 8.93)nmol/l] was significantly less than that of patients without diabetic cranial neuropathy [(37.19-± 9.74)nmol/L,P ＜ 0.01].Serum ferritin levels were positively correlated with 25-(OH) vitamin D3 (r =-0.59,P ＜ 0.01).Multivariate unconditional Logistic regression analysis showed that diabetic neuropathy was negatively correlated with 25-(OH) vitamin D3 (P ＜ 0.05).Conclusions The increases of serum ferritin and 25-(OH) vitamin D3 are closely related to the occurrence and development of diabetic cranial neuropathy,which provides the theoretical basis for clinical intervention therapy.

Objective To compare the in-hospital and follow-up clinical results of percutaneous coronary intervention(PCI)and coronary artery bypass grafting(CABG)in patients of left ventricular dysfunction with coronary artery disease.Methods 147 patients with left ventricular dysfunction were divided into PCI group(n=60)and CABG group(n=87).Clinical,angiographic and revascularization data were collected for analysis.Patients were by SPSS 13.0 software.P value of less than 0.05 was considered statistically significant.Results In-hospital MACCE rates and mortality ofthe two groups were comparable[(6.7%vs 9.2%,P＞0.05)and(1.7%vs 8.0%,P＞0.05)].Multivariate Logistic regression analysis indicated that in-hospital MACCE risk of the two groups were similar(OR≥3.03,95%CI 0.27～34.48,P＞0.05).22-month follow-up showed no signficance in MACCE rates (16.0%vs 13.8%,P＞0.05)and in repeated revaseularization rates(8.O%vs 1.7%,P＞0.05)between the two groups.Multivariate Cox regression analysis indicated that follow-up MACCE risk of the two groups were comparable (HR≥1.35,95%C/0.44～4.13,P＞0.05).Conclusion In coronary artery disease patients with left ventricular dysfunction,PCI and CABG have similar in-hospital and long-tem MACCE rates.Long-terra effect of PCI would be further increased with the wide use of drug-eluting stents.
