Objective To explore the value of different surgical methods in the treatment of the displaced femoral neck fracture of the elderly. Methods An follow up study was done on 89 cases older than 65 years who were treated with internal fixation, femoral head arthroplasty and total hip joint replacement between 1998 and 2003 to compare the difference upon operation time, blood loss, duration of hospitalization, joint function evaluation one and two years after operation, complications and reversion rate. Results The internal fixation group had the shortest operation time and hospitalization and the least blood loss but the longest immobilization time, highest complication rate and reversion rate as well as the worst joint function. While the total hip joint replacement group had the least immobilization time, the lowest complication rate and reversion rate, best joint function but required better health condition. The femoral head arthroplasty group had the least operation injury but had relative higher reversion rate and worse joint function compared to the total hip joint replacement group. Conclusion Total hip joint replacement is suitable for the displaced femoral neck fractures of the elderly, especially those who are active have relative longer life expectancy and good general condition.

This study was aimed to assess the proportion and causes of misdiagnosis of pancreatic cancer (PC), and the effects of misdiagnosis on and treatment of PC, so as to sum up experiences and improve the diagnosis and treatment. 1027 cases with confirmed diagnosis of PC were retrospectively analyzed in detail. The patients were divided into misdiagnosed group and a group with correct diagnosis. The relevant data of the two groups were analyzed by stastical methods, and the differences between them were assessed. It was found that 586 cases (57 1%) were misdiagnosed.Fifty five diseases were involved in misdiagnosis, among them gastritis and duodenitis, peptic ulcer, virus hepatitis, cholecystitis and cholelithiasis, chronic pancreatitis wese the commonest. The differences of duration of diagnosis, main symptoms, resection rate, and half year survival rate between misdiagnosed group and correct diagnosis group were significant. It is concluded that PC is often misdiagnosed as other diseases. Early diagnosis and treatment is critical to the prognosis. The physician should be aware that PC may present a veriety of clinical manifestations, and therefore he or she should analyze comprehensively the symptoms and signs in order to improve diagnosis and treatment.

Objective To determine the effects of polymorphism of A9570G in angiotensin I converting enzyme 2 gene ( ACE2) gene on cardiac dysfunction and ventricular remodeling after myocardial infarction. Methods 252 patients with old myccardial infarction were included in this study. They were classified according to their polymorphisms of ACE 2 gene analyzed by polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). Echocardiograms were used to determine left ventricular end diastolic diameters (LVEDd) , Left ventricular mass index (LVMI) , mitral flow pattern early diastolic and late diastolic peak flow ratio (E/A) and left ventricular ejection fraction ( LVEF). Results In male, LVEDd, LVMI, and LVEF had significant difference among ACE2 genotypes ( t = 2. 609,3.527and 2.063, P =0.010,0.001 and 0.041), and no significant differences in E/A( t =0.689,P =0.492). In female,LVEDd, LVMI, E/A and LVEF had no significant difference among ACE2 genotypes( F =0. 848, 0.077,0. 985 and 1.611, P = 0. 432,0. 926,0. 377 and 0. 205 ). Conclusion The polymorphism of A9570G in ACE2 gene may be associated with cardiac dysfunction and ventricular remodeling after myocardial infarction in male. ACE 2 gene polymorphism may be a genetic factor on cardiac dysfunction and ventricular remodeling after myocardial infarction.

Aim To investigate the protective effects of Diterpene Ginkgolides Meglumine Injection(DGMI)on SY5 Y cells damaged by oxygen-glucose deprivation and its functional mechanisms.Methods After 4 h of OGD,the cells were treated with 25 mg·L-1 drugs for 1 h.Subsequently,cell viabilities were measured by cell counting kit-8(CCK-8 kit)and cell apoptosis was measured by flow cytometric analysis.Furthermore, the mitochondrial membrane potential was detected by rhodamine123 staining.The levels of phospho-p38, phospho-p53,Bcl-2,Bax and cleaved caspase-9/3 were evaluated by western blot.Results DGMI signif-icantly increased the cell viabilities of SY5 Y cells dam-aged by OGD,and reduced OGD-elicited dissipation of mitochondrial membrane potential and cell apoptosis. Furthermore,DGMI also reduced p-p38,p-p53,Bax/Bcl-2 ratio,cleaved caspase-9 and cleaved caspase-3. Conclusion DGMI shows good neuroprotective effects on SY5 Y cells after oxygen-glucose deprivation.The underlying mechanisms may be associated with the sup-pression of p38/p53/Bcl-2 /caspase-9/caspase-3 sig-naling pathway.
