Objective To study the effects of Tongqiao-Huoxue decoction on neuron apoptosis in the CA1 region of the hippocampus and the serum nidogen expression of vascular dementia(VaD) rats and to investigate its mechanism. Methods 40 healthy male SD rats were randomly divided into a normal group, a sham operation group, a model group, a TCM group, and a placebo group. VaD rat models were established by Olsson method. After the models were successfully prepared, the rats in the TCM group were fed Tongqiao-Huoxue decoction, the rats in the placebo group were fed distilled water. Morris water maze test was adopted to investigate their learning and memory abilities, TUNEL was used to assay hippocampal CA1 neurons apoptosis, ELISA kits was used to detect Nestin serum levels . Results The neuron apoptosis index in the CA1 region of the hippocampus in the TCM group was(37.01±2.23)%,which was(55.15±1.54)%in the placebo group;the difference was statistically significant(P<0.05).The serum nidogen was(4.47±0.31)ng/L in the TCM group, which was(3.42±0.43)ng/L in the placebo group;the difference was statistically significant(P<0.05). Compared to the VaD group, escape latency in the TCM group in the third, forth, and fifth day was significantly shorter(P<0.05), the number of cross platforms were significantly increased(t=3.521, P=0.000). Conclusion Tong qiao-Huoxue decoction can improve learning and memory impairment in VaD rats, which may be associated with its increasing serum nidogen expression and decreasing the neuron apoptosis in hippocampal CA1.

[Objective]To investigate the clinical features,reasons of missed diagnosis and treatment for ipsilateral fractures of femoral neck and shaft.[Method]Twelve cases of ipsilateral fractures of femoral neck and shaft treated from 1999 to 2005 were retrospectively reviewed.Seven cases' neck fractures were diagnosed separately before operation,2 cases' were diagnosed during operation and 3 were diagnosed after operation.Among the 12 cases,3 cases were treated with reconstructive intramedullary nail to fix both shaft and neck fractures;2 cases were treated with DHS to fix both shaft and neck fractures;1 case was treated with retrograde interlocking intramedullary nail to fix shaft fracture and with canulated screws to fix neck fracture;2 cases were treated with interlocking intramedullary nails and canulated screws;1 case combined supracondylar fracture of femur,was treated with LISS-DF to fix shaft and supracondylar fracture,canulated screws to fix the neck fracture;the neck fractures were found in 3 cases after shaft fixation with plate,then fixed with canulated screws.[Result]All cases were followed up for 1~6 years,with an average of 3.4 years.All femoral shaft fractures were united and 11 neck fractures were united,1 neck fracture was malunion,1 case was osteonecrosis of femoral head.[Conclusion]The ipsilateral fracture of femoral neck and shaft is rare,and the neck fracture is easy to miss diagnosis.The orthopaedic surgeons should consider the femoral neck fractures by analyzing the mechanism of high energy injury patient with femoral shaft fracture.Pelvic X-ray should be taken conventionally or CT scan when necessary.The surgical treatment for ipsilateral fractures of femoral neck and shaft depends on the position of femoral shaft,and the situation of femoral neck.

Sixty-two elderly patients with distal radius fractures after fixation with small splints were enrolled in the study from January to December 2014.Patients were randomly divided into intervention and control groups with 31 cases in each group.Patients in both groups received comprehensive prevention for hand swelling, those in intervention group were given additional external administration of sodium aescinate gel (SAG), 1 g, t.i.d for 7 d.Swelling score and visual analogue scale (VAS) were documented before and 3, 7 d after intervention.At the time of fracture healing, the wrist functions, including motions of flexion-extension, motions of radial-ulnar and motions of pronation-supination were examined.At 3 and 7 d after intervention, the swelling score(1.22 ±0.69 vs.1.65 ±0.75 and 0.64 ±0.42 vs.0.96 ±0.71) and VAS(1.96 ±1.27 vs.2.85 ±1.40 and 1.11 ±0.65 vs.1.86 ±1.09)of intervention group were lower than those of control group (all P<0.05).At the time of fracture healing, the wrist motions of flexion-extension [(83.7 ±8.6) vs.(77.6 ±7.1)%], motions of radial-ulnar [(83.0 ±7.6) vs.(78.2 ±8.7)%] and motions of pronation-supination [(81.0 ±7.0) vs.(76.2 ±7.5)%] of intervention group were higher than those of control group ( P <0.05 ) .The results indicate that SAG can reduce swelling, relief pain and promote the recovery of wrist function in elderly patients with distal radius fractures.

Objective To explore the effectiveness of bilevel positive airway pressure(Bipap)ventilation via nasal/ mouth mask in patients with respiratory failure secondary to the acute exacerbation of chronic obstructive pulmonary diseases(COPD).Methods 40 patients were randomly submitted either to standard therapy(consisting of medical,oxygen and physical therapy)plus BiPAP or to standard therapy.Clinical manifestation were comparatively analyzed before and after 4 hours and 7 days of treatment in each group.Results After 4 hours and 7 days of treatment by BiPAP,patients showed a significant improvement in PaCO_2,and clinical manifestation,and there was a significant difference between the two groups.Conclusion Bipap ventilation is effective in patients with respiratory failure during acute exacerbation of COPD.

Objective To evaluate the role of transanal ileus tube decompression in the management of malignant obstruction of left-sided colon. Methods With the help of colonoscopy and radiography, 11 cases of left-sided malignant colonic obstruction were treated with transanal ileus tube insertion into the proximal obstruction site for the decompression of the dilated bowel. Curative effects were evaluated according to patient’s symptom relief, bowel sounds, abdominal circumference, intra-abdominal pressure, and plain abdominal radiography. Results Symptoms of acute intestinal obstruction were relieved in all the 11 cases after ileus tube decompression for 3~5 days. Laparoscopic or open primary colectomy was performed in 7 patients with resectable tumor. Postoperative follow-up observations for 1~18 months (median, 11 months) showed no complications like anastomotic leakage. Conclusions Transanal ileus tube decompression in the management of malignant obstruction of left-sided colon is safe and effective.

Objective:To study the expression and significance of apoptosis-related gene tfar19 in normal oral mucosa, oral leukoplakia and oral squamous cell carcinoma.Methods:The expression of TFAR19 was observed in 17 cases of oral normal mucosa, 60 of oral leukoplakia and 30 of oral squamous cell carcinoma by immunohistochemical stain.Results:①Positive expression of TFAR19 was observed in 88.2% of the cases of oral normal mucosa, 63.3% of oral leukoplakia, and 30% of oral squamous cell carcinoma. There was statistical difference between each two groups (P

The relationship between immune vasculitis and atherosclerosis was studied. The experimental model of weanling rabbits for immune vasculitis was reproduced by intravenous injection of 10% bovine serum albumin. There were 6 groups: group A, 25 weanling rabbits with immune vasculitis subject to coronary arteriography; group B, 10 normal mature rabbits subject to coronary arteriography; group C, 10 weanling rabbits subject to coronary arteriography; group D, 8 weanling rabbits with vasculitis and cholesterol diet; group E, 8 weanling rabbits receiving single cholesterol diet; group F: 8 weanling rabbits receiving basic diet. Four weeks later, coronary arteriography was performed in groups A, B and C. The rabbits in groups D, E and F were sacrificed for the study of pathological changes in the coronary artery after 12 weeks. The results showed that the dilatation of coronary artery occurred in 6 rabbits of group A, but in groups B and C, no dilatation of coronary artery appeared. In comparison with group E, more severe atherosclerosis occurred in group D, showing the thickened plaque, fibrous sclerosis and atherosclerotic lesion. Percentage of plaques covering aortic intima, incidence of atherosclerosis of small coronary arteries and degree of stenosis of coronary arteries were significantly higher in group D than in group E (P < 0.01). No atherosclerosis changes were found in group F. It was concluded that in the acute phase, the serum immune vasculitis can induce the dilatation of coronary artery of some weanling rabbits, and aggravate the formation of atherosclerosis in rabbits fed with cholesterol diet. Immune vasculitis is a new risk factor of atherosclerosis and ischemic heart disease.

To investigate the change in renal CD11a and myeloperoxidase (MPO) contents and renal function during ischemia-reperfusion injury (IRI) of rat kidney, as well as the role of lymphocyte function associated antigen-1 (LFA-1) played in renal IRI, we utilized a rat model of renal IRI to detect the renal tissue contents of CDlla and MPO and renal functioa The results showed that the levels of CD11a and MPO were very low in normal renal tissue, but increased significantly in ischemia reperfusion. Renal failure was presented in rats with IRI. The levels in the ischemia-60min-reperfusion group were higher than those in the ischemia-30min-reperfusion group in the same time points. Our conclusion is the levels of CD11a and MPO in rat renal tissue increase significantly during renal IRI. LFA-1-mediated leukocyte adherence plays an important role in renal IRI. Up-regulation of CDlla further elucidates the mechanism of relation between IRI and acute rejection: more heavier IRI is, more possible acute rejection would be.
