Objective To explore the effect of Zhibitai capsule in the treatment of elderly coronary artery disease patients with normal lipid,and to investigate its influence on prognosis.Methods 90 elderly coronary artery disease patients with normal lipid were randomly divided into the control group (n =30),the treatment group 1 (n =30) and the treatment group 2 (n =30).The control group received routine treatment,once a day for 2 months.The treatment group 1 received the Xuezhikang capsule,once a day for 2 months.The treatment group 2 received the Zhibitai capsule,once a day for 2 months.The expression of inflammatory factors,the level of blood fat,the maintenance rate of sinus rhythm and the incidence rate of embolism before and after treatment were compared among the three groups.Results After treatment,the levels of hs-CRP,IL-6,TNF-α,TC,TG,LDL-C of the three groups were significantly lower than those before treatment(P ＜ 0.05),and the level of HDL-C was significantly higher than before treatment (P ＜ 0.05).The levels of hs-CRP,IL-6,TNF-α,TC,TG,LDL-C in the treatment group 2 were significantly lower and the level of HDL-C was significantly higher than the other two goups (P ＜ 0.05).Moreover,the differences between the control group and the treatment group 1 were not statistically significant.The maintenance rate of sinus rhythm of the treatment group 2 was significantly higher and the incidence rate of embolism was significantly lower than the treatment group 1.Conclusion For elderly coronary artery disease patients with normal lipid,the Zhibitai capsule has ideal effect in controlling inflammation,which can delay the progress of atherosclerosis,decrease the major cardiovascular events and better than the Xuezhikang capsule.

[Objective]To investigate the best internal fixation methods of upper segment complicated femoral fractures(USCFF).[Method]Fifty-two cases(54 limbs) with USCFF were treated.In all patients open fracture reduction with use of internal fixation were done.Intramedullary interlocking nails(IIN) were used to treat 32 cases(34 limbs) of adult's USCFF and 130? plate were used to treat 20 cases of children's USCFF.Thirty-six limbs of them were closed fractures,and 18 limbs were opene.Measures of auto-ilium transplant(5 limbs),homolegous allograft bone transplant(10 limbs)were also taken.[Result]Fifty-two patients were followed-up from 9 to 40 months with an average of 16 months.Infection,fracture nonunions,malunion and femoral head necrosis complications were not found.The average period of union of adult and children fractures was respectively 6.8 months and 6.5 months.The long term effect was evaluated according to Ma Yuanzhang's evaluation standard,94.4 percent showed excellent function of joints and limbs.[Conclusion]Appropriate selection of internal fixation according to the age of patients and satisfactory fracture reduction are key points to improve outcome of USCFF.IIN in treating fiacture of adult and 130? plate in treating fracture of children are more ideal selections.

Objective To evaluate the advantage of video-assisted mini thoracotomy for patients with esophageal cancer compared with routine open thomcotomy.Methods Perioperative clinical results were compared between 24 csses received VAMT(test group)and 26 cases underwent routine open thoracotomy(control group)during the same period.All the cancer stages were T2-3N0-1M0.Results This study showed that VAMT Was a minimally invasive swgew with shorter operation time(40.0±3.3)min vs.(70.3±3.2)min,P＜0.05)and had less bleeding volume both during and after operation compared to the control group(108.1±15.2)ml V8.(200.1±11.3)ml,(380.8±45.4)ml vs.(780.1±52.2)ml,P＜0.05).No significant differences were observed in the two groups with respect to complication occurrence rate(4.2%vs.19.2%,P＞0.05).Conclusion It is suggested that VAMT is safe,reliable and less invasive in the treatmem of esophagus carcinoma.

Aim To explore the hemodynamic change of elderly isolated hypertension(EISH). Methods Color doppler ultrasonography were applied to examine thirty EISH patients and twenty eight elderly healthy subjects. The left ventricular systolic function as well as hemodynamic parameters were measured. Results The indices of left ventricular systolic function in EISH group such as SV,CO,EF and CI were obviously higher than those of control group(P<0.05),Linear relevant analysis show that pulse pressure was remarkable related to SV,CO,EF and CI in EISH group,with r value 0.43,0.56,0.46,0.45 respectively.Conclusion EISH patients apparently had ventricular systolic dysfunction and hemodynamic abnormality. Pulse pressure may be associated with development of sysytolic dysfunction.

Objective To investigate the effect of 23.4% hypertonic saline(HTS)on intracranial pressure(ICP), cerebral peffusion pressure(CPP), cerebral blood flow(CBF)in poor-grade patients with subarachnoid hemorrhage(SAH).Methods Sixteen patients(Glasgow coma score ≤ 8)with poor-grade SAH received 23.4% hypertonic saline intravenously for elevated ICP.ICP, mean arterial pressure(MAP), CPP and the middle cerebral artery flow velocity(FV)were observed and recorded before and at 30, 60, 90,120, 150, 180 min after the injection respectively.Results Thirty minutes postinfusion, a significant increase in MAP, CPP, FV was seen together with a decrease in ICP(P<0.05).ICP remained reduced for 180 minutes, CPP and FV remained elevated for 90 minutes(P < 0.05).Conclusions HTS can significantly decrease ICP and improve CBF in patients with poor-grade subarachnoid hemorrhage and may be used for reversal of pathophysiologic changes caused by cerebral ischemia.

Objective: To study the etiology, clinical manifestation, diagnosis, treatment and precaution of pulmonary embolism following major surgery of gastrointestinal malignant tumors. Methods: Thirty-two cases of pulmonary embolism following major surgery of gastrointestinal malignant tumors were analyzed retrospectively. Results: The most common clinical manifestations were dyspnea, thoracodynia and palpitation. The D-dimer of all cases was positive. The examination of pulmonary arteriography by spiral computed tomography might assist the diagnosis of the disease. Twenty-two patients were discharged through the treatment of oxygen therapy and anticoagulation. Six patients recovered through the treatment of assisted respiration by respirator, thrombolysis and anticoagulation. Four patients died of respiratory failure. Conclusion: The operation of gastrointestinal malignant tumors can increase the incidence of pulmonary embolism. Arteriography by spiral computed tomography and D-dimer can assist the diagnosis and thrombolysis and anticoagulation were effectivel for the treatment.

Objective To investigate the significance of preoperative and postoperative enteral nutrition support in gastric cancer patients with nutritional risk.Methods The clinical data of 72 gastric cancer patients with nutritional risk admitted in our department were analyzed.All the patients were randomly allocated into two groups.36 patients in the control group received only intravenous nutrition postoperatively (PN group).36 patients in the treatment group received enteral nutrition support from the fifth day before operation to eighth day after operation (EN group).The body weight,total protein,albumin,transferrin and prealbumin were measured on the fifth day before operation,the operation morning,the first day and the eighth day after operation.Results On the operation morning,the transferrin and prealbumin of the EN group were higher than those in PN group significantly(P ＜0.05).In the eighth day after operation.the treatment group patients showed significant increase in the body weight,total protein,albumin,transferrin and prealbumin compared with those in the control group(P ＜ 0.05).On the operation morning,the transferrin and prealbmnin of EN group were increased significantly than on the fifth day before operation(P ＜ 0.01).Conclusion The preoperative and postoperative enteral nutritional support can improve the nutritlonal condition in the gastric cancer patients with nutritional risk.The preoperative enteral nutritional support can improve the patients' nutritlonal condition and reserves before operation,and reduce adverse reaction of enteral nutrition.

Objective To studiy the surgical outcomes of children with congenital aortic stenosis (AS),and summarized the experience of surgical procedures.Methods From February 2006 to November 2011,a total of 49 consecutive children with AS underwent surgical treatments.Twenty-nine patients were male and 20 patients were female.The median age was 17 months (1 month to 14 years),and median weight was 15.6 kg (3.2-47.0 kg).Peak AS gradients was (74.9 ±20.4)mmHg (45-123 mm Hg) before surgery.Fourteen patients had isolated congenital AS,4 had combined moderate-to-severe aortic insufficiency (AI).Thirty-Three patients had associated cardiac anomalies,including ventricular septal defect,atrial septal defect,patent ductus ateriosus,coarctation of aorta,subaortic stenosis,and supravalvular mitral stenosis.Thirty-one patients underwent aortic valvotomy,9 valvuloplasty,2 Aortic valve replacement (AVR),1 Ross procedure,2 Ross-Konno procedure,and 4 Konno/AVR.Median follow-up was 20 months (2-55 months).Clinical and echocardiographic follow-up data were analyzed.Results There was 1 postoperative death who died of heart failure due to severe mitral valve insuffciency.Latest follow-up data showed that the survivals performed in satisfactory cardiac function.Left ventricular ejection fraction (LVEF)was 0.69 ±0.10,and fraction shortening (FS) was 0.38 ±0.09.Peak AS gradients decreased significantly after surgery to (38.6 ± 15.8) mm Hg (20-73 mm Hg),P ＜ 0.001.One patient needed reintervention because of severe recurrence of adhesion in the commissure 3 months after the previous surgery.Totally 31 patients underwent simple valvotomy procedure.Postoperative AI was none or trace in 5,mild in 20,and moderate in 6.Two surgical techniques were used to repair the aortic valve according to the anatomy of the valve and the cause of insufficiency,including commissuroplasty in 6 and pericarial casp extension in 3.Nine patients underwent valvuloplasty procedure,post-operative AI was none or trace in 3,mild in 5,and moderate in 1.We put more attention to the 7 patients who had moderate AI valvotomy or valvuloplasty,and the latest follow-up showed that these patients were in good condition and there was no deterioration the degree of AI.Conclusion Long-term outcomes show that aortic valvotomy and valvuloplasty are reliable and effective approaches for congenital AS in children.When moderate-to-severe AI exists,other procedures such as Ross,Ross-Konno,AVR,or Konno/AVR are preferred.

Objective To evaluate the effect of neoadjuvant chemotherapy on lymph node micrometastasis and DC cell number in stage Ⅲ gastric cancer patients.Methods Lymph node micrometastases in pathologically negative lymph nodes from 76 stage Ⅲ gastric cancer patients [56 cases with neoadjavant chemotherapy (NCT) and 20 cases without],were assessed by cytokeratin-20 antibody.Dendritic cells (DC) in HE positive lymph nodes,HE negatives near tumor foci and HE negatives far foci were assessed by CD83 antibody respectively.Patients were divided into four groups:group 0 (20 cases without NCT),group 2 (two courses of NCT in 29 patients),group 3 (three courses of NCT in 16 patients),group 4 (four courses of NCT in 11 patients).Results In NCT group there were two patients with micrometastases (2/56).All the patients were with micrometastases in control group (20/20).Difference was statistically significant (P =0.000).In HE-positive lymph node group:the number of CD83-positive DC in 2 times group,3 times group,and 4 times group when compared with no chemotherapy group were statistically significant (P20 =0.001,P30 =0.000,P40 =0.000).In HE-negative lymph node near foci group:the number of CD83-positive DC in 3 times group,and 4 times group compared with 0 group were statistically significant increased (P30 =0.001,P40 =0.001).In HE-negative lymph node far foci group:the number of 4 times group was significantly higher than 0,2 and 3 group (P40 =0.000,P42 =0.000,P43 =0.001).Conclusions Neoadjuvant chemotherapy is effective in the prevention of lymph node micrometastases in stage Ⅲ gastric carcinoma and it increases the number of mature dendritic cells in lymph nodes.
