Objective: To study therapeutic effect and mechanisms of inhalation of drug-oxygen Fuchong Xiangye for treatment of vascular dementia. Methods: 123 cases were randomly divided into treatment group and control group by single-blind. Thertapeutic effects, superoxide dismutase (SOD) activity in red cells, plasma lipid peroxide, triglyceride, serum cholesterol and high density lipid protein (HDL) levels, and electroencephalogram were investigated before and after treatment. Results: The improvement of symptom scores and the above indexes after treatment in the treatment group were more obvious than those in the control group, with no reserve reaction in both groups. Conclusion: Inhalation of drug-oxygen Fuchong Xiangye has a better therapeutic effect on vascular dementia, and the mechanism is related with decrease of blood lipid, and increase of HDL and SOD.

Objective To study the influence of carboxymethyl-chitosan(CM-chitosan)on chondro- cyte apoptosis induced by recombinant human interleukin-1?(rhIL-1?)and explore its mechanism.Methods Rabbit chondrocytes were isolated and cultured.Chondrocytes were pretreated with different concentrations of CM-chitosan for 1 h,then 10 ng/ml IL-1?were added into the culture medium.After 24 h,the apoptotic rates of chondrocytes were measured by flow cytometry with AnnexinⅤ-FITC and PI staining.The morphology of nuclei was observed by fluorescent microscopy with Hoechst 33342 staining.The mitochondrial membrane po- tentials were tested by confocal laser scanning microsocopy with Rhodamine-123 and ATP contents were mea- sured by luciferase reaction.Results CM-chitosan could inhibit chondrocyte apoptosis and restore the func- tion of mitochondria induced by IL-113 in a dose-dependent manner.Conclusion CM-ehitosan can inhibit chondrocyte apoptosis by protecting mitochondrial function.

Objective To compare the efficacy of internal fixation with non-operative treatment of traumatic flail chest combined with sternal fracture.Methods A retrospective review was made on 102 patients with traumatic flail chest combined with sternal fracture treated from January 2007 to January 2014.There were 71 patients in operation group and 31 patients in non-operation group.Operation group was allocated to pure titanium rib plating (Group Ⅰ,22 cases),porous titanium screw fixation (Group Ⅱ,20 cases),and nickel-titanium memory alloy sternal rib plating (Group Ⅲ,29 cases).Rib traction was performed in non-operation group.Clinical results and incidence of complications were compared between the two groups.Results At 24 and 72 hours,operation group was superior over non-operation group with regard to HR [(100.4 ± 9.5) times/min vs (105.2 ± 10.1) times/min,(92.1 ± 9.9) times/min vs (102.1 ± 9.2) times/min],MAP [(97.7 ± 14.5) mmHg vs (91.0 ± 13.3) mmHg,(112.5 ± 15.2) mmHg vs (93.1 ± 13.8)mmHg] and CVP [(7.8 ±3.7)cmH2O vs (9.4 ±3.8)cmH2O,(6.2 ±2.9)cmH2O vs (9.1 ±3.2) cmH2 O] (P ＜ 0.05).Duration in ICU [(5.1 ± 0.8) days vs (9.3 ± 1.1) days],ventilation time [(4.5 ±1.0)days vs (8.2 ± 1.4)days],hospitalization time [(14.6 ±3.5)days vs (23.3 ±4.4)days] and incidence of complications were significantly lower in operation group than in non-operation group (P ＜ 0.05).Two months after discharge,tidal volume (VT) [(0.52 ±0.04)L vs (0.40 ±0.03)L],inspiratory capacity (IC)[(1.99 ±0.45)L vs (1.22 ±±0.33)L],forced vital capacity (FVC) [(3.52 ±0.51)L vs (2.44 ±0.42)L],total lung capacity (TLC) [(5.41 ±0.82)L vs (3.72 ±0.56)L] and forced expiratory volume in one second (FEV1) [(2.80 ± 0.43) L vs (1.95 ± 0.50) L] showed significantly better results in operation group than in non-operation group (P ＜ 0.05).Operation time,intraoperative bleeding and daily drainage volume were (38.8 ±9.2)min,(43.5 ±7.6)ml and (10.9 ± 1.1)ml in Group Ⅱ versus (62.5 ± 10.1)min,(100.0 ± 10.5) ml and (26.8 ±3.1)ml in Group Ⅰ and (49.3 ±9.6)min,(61.4 ±8.3)min and (19.8 ±1.6)ml in Group Ⅲ (P ＜ 0.01).Conclusion For traumatic flail chest combined with sternal fracture,the internal fixation should be done as early as possible so as to reduce incidence of complications.Relatively,porous titanium screw fixation has better clinical outcome.

OBJECTIVE: To investigate and analyze the status of anxiety and depression among patients with four types of peripheral vertigo. METHOD: The clinical data of patients with one of the four types of peripheral vertigo, namely benign paroxysmal positional vertigo (BPPV), vestibular migraine (VM), Menière's disease (MD), and vestibular neuritis (VN), were collected. Thorough otological and neuro-otological examinations were performed on these patients, and their status of anxiety and depression were assessed using self-rating anxiety scale (SAS) and self-rating depression scale (SDS). RESULT: A total of 129 patients with one of the four types of peripheral vertigo(49 cases of BPPV, 37 cases of VM, 28 cases of MD and 15 cases of VN) were included in the study. The scores of SAS and SDS were higher in the patients with VM or MD than those with BPPV or VN (P < 0.05), and the incidence of anxiety (VM = 45.9% MD = 50.0%) and depression (VM = 27.0% MD = 28.6%) were higher in the patients with VM or MD than those with BPPV or VN (P < 0.05). Paired comparisons showed the differences between the incidences of BPPV and MV groups, BPPV and MD groups, and MD and VN groups were statistically significant (P < 0.05). CONCLUSION Among patients with different types of peripheral vertigo, anxiety/depression is more common in patients with VM or MD. This may be due to the different mechanisms involved in different types of vertigo, as well as differences in the prevention and self-control of the patients against the vertigo.

Objective Through the analysis of cases,to improve the cognition of clinicians on extracranial vas-cular embolism diseases(VED)in children.Methods The clinical information included incidence trend,thrombophi-lia,clinical features,treatment and prognosis of 29 children with VED,who were admitted from January 201 1 to Decem-ber 201 5 in Nanjing Children′s Hospital Affiliated to Nanjing Medical University,and retrospectively analyzed.Results The annual rate of VED increased from 0 to 1 .49 per 1 0 000 hospital admissions from January 201 1 to December 201 5.In 29 cases,there were 20 male and 9 female,with an average age of 6.03 years old (2 h -1 3.83 years old).In-fants accounted for >20%(6 /29 cases).The average age of the female,non infected group,rheumatic disease group and venous thrombosis group was higher than that of the male,the infection group,the non rheumatic disease group and the arterial embolization group,but there was no significant difference(all P >0.05).Thrombophilia were as follows:in-fection disease,heart disease,kidney disease syndrome,rheumatoid disease,tumor,and twins embolization syndrome. Risk factors included central venous line,immobility,dehydration,glucocorticoids use,etc.Heart disease was the leading cause of non thrombotic embolism,while other thrombophilic diseases resulted in thrombotic embolism.Pulmonary em-bolism was mainly seen in patients with severe pneumonia,especially mycoplasma pneumoniae pneumonia (MPP ).The older the age,the more typical clinical manifestations,and significantly elevated D dimer,fibrin/fibrinogen degradation products tips VED.Treatment depends on the degree of risk.Thirty -seven point five percent(3 /8 cases)of children with arterial embolism were less than 1 year old,and the mortality 25.00% (2 /8 cases)was significantly higher than that of venous thrombosis 1 7.65%(3 /1 7 cases)and 1 1 .76% (2 /1 7 cases).Conclusion Heart disease mainly cause arterial embolism and infection,while nephritic syndrome and rheumatic disease mainly cause venous embolism.Pulmona-ry embolism is mainly seen in children with severe pneumonia,especially MPP.The risk of arterial embolization is higher than that of venous embolism.

Objective To study the methods and skill of vena cava filter placement via the antecubital access. Methods Six patients with DVT (4 males and 2 females, mean age of 62) underwent vena cava filter placement via the antecubital access in Huashan Hospital from Oct. 2004 to May. 2006. The right basilic vein was punctured with the use of micropuncture technique. SNF (Simon nitinol filter, Bard)was inserted through its carrier into the 90-cm-long sheath. The filter was then deployed with a standard fashion in the IVC, 5 cm inferior to the renal vein. Results The filter was once placed successfully in all six patients within average time of 25 min without complications, but with good healing, exclusion of bleeding and no phlebitis. The position of filter was accurate without deviation and no occurrence of pulmonary embolism. Conclusions vena cava filter placement via antecubital access is easy, minimal invasive, no need of lying in bed postoperatively. It is beneficial for DVT patients as an alternative for the contra-indication to femoral venous access.
