2. Analysis of risk factors for hemorrhagic transformation after cerebral infarction
Chinese Journal of Cerebrovascular Diseases 2012;9(2):72-76
Objective: To investigate the risk factors for hemorrhagic transformation (HT) in patients with cerebral infarction. Methods: The clinical data of 960 patients with cerebral infarction admitted to the Department of Neurology, Hangzhou First People's Hospital Affiliated to Nanjing Medical University were analyzed retrospectively. They were divided into HT group (n =90) and non-HT group (n =870) according to whether they had HT or not. The blood pressure, postprandial and fasting blood glucose, cholesterol levels, infarct size detected by imaging, atrial fibrillation and thrombolysis within 24 hours of admission, anticoagulant therapy before or after admission, previous history of anti-platelet aggregation therapy and TOAST classification in both groups were observed. The risk factors for HT were identified by univariate chi-square test and multivariate logistic regression analysis, and the incidences of HT in various types of cerebral infarction in the TOAST classification were compared. Results: Circled digit oneThe results of multivariate logistic regression analysis showed that massive cerebral infarction (P = 0.000, OR = 10. 519, 95% CI 6. 600-16. 766), atrial fibrillation (P = 0. 006, OR = 1. 913, 95% CI 1. 206-3. 003), thrombolysis (P = 0. 033, OR= 2. 502, 95%CI 1.078-5.805), anticoagulation (P = 0. 000, OR = 7. 877, 95% CI 2. 491-25. 911), and postprandial glucose ≥10 mmol/L or fasting glucose ≥7. 0 mmol/L (P = 0. 011, OR = 0. 822, 95% CI 1. 146-2.897) were the independent risk factors for HT. Systolic blood pressure ≥ 180 mm Hg and/or diastolic blood pressure ≥ 110 mm Hg, high cholesterol (≥ 5. 98 mmol/L) , and the history of anti-platelet aggregation were not the independent risk factors for HT. Circled digit twoIn the TOAST classification, the HT incidence in patients with cardioembolic cerebral infarction was the highest (21. 4% , 34/159), the HT incidence of small artery occlusion was lower (1. 1%, 2/181 ), and the HT incidence of large artery atherosclerosis was 8. 6% (51/593). Conclusion: Massive cerebral infarction, atrial fibrillation, thrombolysis, anticoagulation, postprandial glucose ≥ 10 mmol/L or fasting glucose ≥ 7. 0 mmol/L are the independent risk factors for HT. Cardioembolic cerebral infarction is one of the major reasons for the occurrence of HT.
5.Clinical Significance of Measuring Exhaled Gaseous Signal Molecules
Journal of Applied Clinical Pediatrics 1994;0(04):-
Exhaled gaseous signal molecules such as nitric oxide(NO),carbon monoxide(CO) and hydrogen sulfide(H2S) can be measured with a non-invasive technique.The fraction of NO level in exhaled gaseous of patients with airway inflammatory illness(such as bronchial asthma) significantly increases.No in exhaled gaseous is one of the markers in the diagnosis of asthma,and it is also a marker of anti-inflammatory response for patients with asthma.The fraction of CO level in exhaled gaseous of patients with bronchial asthma is also si-gnificantly elevated.Both NO and CO in exhaled gaseous in other airway inflammatory illness,such as chronic obstructive pulmonary disease,chronic bronchitis and cystic fibrosis are also evidently changed.Measuring exhaled gaseous signal molecules can provide important basis for the diagnosis and treatment of airway inflammatory illness.

AlM: To evaluate the clinical efficacy of canalicular intubation combined with external dacryocystorhinostomy ( ext-DCR ) for treatment of chronic dacryocystitis and upper lacrimal duct stenosis.
METHODS:Thirty-three patients (33 eyes) with chronic dacryocystitis and upper lacrimal duct stenosis who underwent canalicular intubation combined ext-DCR were retrospective analyzed. The silicon tube was indwelt for 6mo. All cases were re-examined 1wk;1, 3, 6, 9mo post-operation, flow of tears, pus excretion and lacrimal duct clearance were observed.
RESULTS: Clear lacrimal duct ratio was 100% in all cases during 1wk~6mo post-operation; Silicon tube was removed 6mo post-operation, 3mo after tube removal, rechecking reported 32 cases with clear lacrimal duct (97%) and 1 case with resistant duct (3%). Two cases ( 6%) with minor lacerations, no other complications were observed.
CONCLUSlON: Canalicular intubation combined ext-DCR is an effective treatment for chronic dacryocystitis and upper lacrimal duct stenosis.

Objective To evaluate the efficacy and clinical feasibility of the computer-assisted full plan- ning system for tibial fracture treatment with intramedullary nailing.Methods After analyzing the functional structure and operative procedures of the system,nine plastic tibia and 12 cadaver lower limbs were used for image mosaicing based on C-arm (PHILIPS BV Libra) fluoroscopic images in the operation room to assess the correctness of the mosaicing and planning algorithms.The plastic tibial model was used for analysis of the mosaicing precision.The cadaver tibial bone was used for reduction experiment with the reduction mechanism to analyze the operation feasi- bility.Results Only 7 to 10 [fluoroscopy time:(19.75?0.61)s] valid C-ann projection images were needed to produce a long bone panorama of the lower limb.The total time for image acquisition and mosaicing was within (4.17?0.86)minutes and the mosaicing precision in the plastic tibial model was (1.26?0.76)mm.The opera- tion of the reduction mechanism was very simple and could be controlled by a surgeon automatically or free of hand. An integrated reduction strategy could be produced for rough positioning in general and elaborate operations in de- tails.Conclusion The computer-assisted full planning system can be used for anatomical analysis based on the C-arm panorama,full surgical planning,virtual simulation,selection of proper intramedullary nails and fracture reduction in treatment of long bone fractures.
