Objective To investigate the level and influencing factors of falls efficacy among older patients with type 2 diabetes (T2DM) .Methods A total of 218 older patients with T2DM were investigated by the modified falls efficacy scale(MFES) and Morse Fall Scale (MFS) ,questionnaire and observation were both used .Results The average score of falls efficacy was 8 .15 ± 2 .91 .The scores were lowest in the items of walking up and down stairs and going to bed and getting out of bed ,and highest were in the items of dressing and sitting down and standing up from a chair .The multivariate linear regression analysis showed that dura‐tion of diabetes ,diabetic complications and fall history were the main factors influencing their falls efficacy .Conclusion Falls in eld‐erly T2DM patients were in the medium level ,and it′s closely related with duration of diabetes ,its complications and fall history .

Objective To investigate the factors predicting endoscopic stone extraction complications during operation and 1 week within operation. Methods The clinical data of 136 patients with common duet stones during endoscopic procedures and 1 week within procedures were collected, and the impacts of the number, size of stones, and the first-attack versus recurrent-attack stone, with or without cholangeitis on the complications during operation and 1 week within operation were analyzed, and the effect of nasobiliary drainage was investigated. Results The success rate in single-stone group was high, the incidences of complications during endoscopy including sphincter hemorrhage, cardiac laceration, hyperamylasemia, acute pancreatitis were significantly lower than those in the multi-stones group ( P < 0. 05 ). The group of < 2 cm stone also had high success rate of stone extraction, the incidences of complications including sphincter hemorrhage, stone impaction, cardiac laceration, hyperamylasemia, acute pancreatitis were significantly lower than those in the ≥2 cm group. The first-attack group had low success rate of stone extraction, the incidences of complications including sphincter hemorrhage, stone impaction, hyperamylasemia, acute pancreatitis and biliary infection were significantly higher than those in the recurrent-attack group. The patients with cholangeitis had low success rate of stone extraction, the incidences of complications including sphincter hemorrhage, hypoxemia, hyperamylasemia, acute pancreatitis and biliary infection were significantly higher than those without cholangeitis. After nasobiliary drainage, the incidences of hyperamylasemia, acute pancreatitis and biliary infection significantly decreased while the incidence of sphincter hemorrhage significantly increased. Conclusions The number, size of stones, and the first-attack versus recurrent-attack stone, symptoms with orwithout cholangeitis could predict the complications of stone extraction;post-ERCP nssobiliary drainage could decrease the complications, but increase the possibility of sphincter hemorrhage.

Objective To evaluate the effects of dexmedetomidine combined with subanesthetic dose of ketamine on the emergence agitation in the patients undergoing thoracotomy.Methods Eighty ASA physical status Ⅱ or Ⅲ patients,aged 55-75 yr,weighing 50-75 kg,scheduled for elective esophageal cancer resection,were randomly divided into 4 groups (n =20 each) using a random number table:normal saline group (NS group),dexmedetomidine group (group D),subanesthetic dose of ketamine group (group K),and dexmedetomidine combined with ketamine group (group DK).In DK and K groups,ketamine 0.5 mg/kg was injected intravenously (within 1 min) at 10 min before the end of the operation.In DK and D groups,dexmedetomidine 0.5 μg/kg was infused intravenously over 10 min starting from 10 min before the end of operation.In group NS,the equal volume of normal saline was infused intravenously over 10 min starting from l0 min before the end of operation.The emergence time,extubation time,duration of ICU stay,occurrence and degree of agitation,and development of cardiovascular events and hypoxemia within 24 h after operation were recorded.Ramsay sedation scores were recorded before induction of anesthesia (T1),immediately after completion of administration at the end of surgery (T2),and at 0,5,10 and 30 min after extubation (T3-6).Results There was no significant difference in the emergence time,extubation time,and duration of ICU stay between the four groups.Compared with group NS,Ramsay sedation scores were significantly increased at T3-6,the incidence and degree of agitation were decreased,and the incidence of cardiovascular events and hyoxemia was decreased in D,K and DK groups.Compared with D or K group,Ramsay sedation scores were significantly increased at T3-6,the incidence and degree of agitation were decreased,and the incidence of cardiovascular events and hyoxemia was decreased in group DK.Conclusion Dexmedetomidine combined with subanesthetic dose of ketamine can prevent the emergence agitation in the patients undergoing thoracotomy,which provides better efficacy than either alone.

Aim To investigate the effects of an angiotensin Ⅱ receptor blocker,candesartan, on aorta oxidative stress-LOX-1 pathway in salt-loaded stroke-prone spontaneously hypertensive rats (SHRSP).Methods 12-week-old salt-loaded SHRSP were treated with candesartan(1.0 mg?kg-1?d-1)or a diuretic, trichlormethiazide(TCM,1.6 mg?kg-1?d-1) or no treatment(n=6) in each for 2 weeks. Age-matched salt-loaded WKY rats were served as control(n=6).Systolic blood pressure(SBP)was measured weekly throughout the 2-week period by means of the tail-cuff method.Thoracic aortas were extracted and 24 h urine was collected.NAD(P)H oxidase subunits(p22 phox, p47 phox and gp91 phox)mRNA expression in aorta were assayed by real-time PCR. LOX-1 and type Ⅳ collogen mRNA expression were examined by RT-PCR. gp91 phox and LOX-1 protein expression in aorta were assayed by immunohistochemistry.Urinary albumin excretion was examined by ELISA.Results At the end of the 2nd week, SBP was significantly higher in salt-loaded SHRSP than that in salt-loaded WKY rats. Treatment with candesartan and TCM significantly decreased SBP in salt-loaded SHRSP at similar levels.NAD(P)H oxidase subunits (p47 phox and gp91 phox)and LOX-1 mRNA expression in aorta were markedly higher in salt-loaded SHRSP than those in salt-loaded WKY rats.Candesartan and TCM had the effect of reducing the systolic blood pressure at similar levels. Candesartan significantly down-regulated aorta p22 phox, gp91 phox,LOX-1 and type Ⅳ collogen mRNA expression and decreased urine albumin excretion in salt-loaded SHRSP(P

Objective To sum up the experience on diagnosis and treatment of intraabdominal bleeding in severe acute pancreatitis (SAP). Methods The clinical data of 37 SAP patients with bleeding complications from Jan 1999 to Jan 2003 were analyzed retrospectively. The causes of bleeding were of erosive (5 cases), infected (20 cases), intra operative/postoperative (10 cases) and coagulopathy (2 cases). Results The mortality was 10% (2/19) for transcatheter arterial embolization (TAE), 30% (7/23) for laparotomy, 50% (2/4) for conservative thepary. The cause related mortality was 0 (0/5), 30% (6/20), 40% (4/10) and 50% (1/2) for erosive, infection, intra/post operative, and coagulopathy respectively. Conclusion In SAP most intra abdominal bleedings are from erosive/infective pseudoaneurysms of splenic artery or/and gastroduodenal artery. The preferred diagnosis methods were CT and selective angiography which often give definite diagnosis. TAE is most effective therapy, when it fails, a surgery is necessary.

Objective To explore the motion features of cervical spine based on continuous X-ray images.Methods The cervical spontaneous continuous multi-frame sagittal images from flexion to extention positions were selected from cervical spondylosis patients (patients group) and healthy adult (normal group).After preprocessing and registration,the trajectory of single vertebral body were recorded,and the feature points of each vertebral body were extracted.Meanwhile,the rel ative geometry parameters and movement rate were calculated.Results The motion trajectory of patients' cervical spine C4-6 were different from healthy people.The angles between the left edge curve of the vertebral body (C4 and C5 vertebra) and the baseline of patients group were smaller than those of normal group in flexion position (all P＜0.05).There were instability in the movement of C4 vertebral body in patient group,and the volatility of the angle change,the rate of change and the frequency were larger.The relative position change of the adjacent single vertebral body in the patient group are smaller.Conclusion Through the preprocessing,registration,parameter extraction and result analysis,the changes of functional features in cervical spondylosis patients are truly reflected.And it also provides a new idea for dynamic analysis of cervical vertebrae based on X-ray images.

The experience in diagnosis and treatment of bleeding complications in severe acute pancreatitis (SAP) by transcatheter arterial embolization was summarized. The clinical data of 19 SAP patients complicated with intra-abdominal bleeding in our hospital from Jan. 2000 to Jan. 2003 were analyzed retrospectively and the therapeutic outcome of TAE was evaluated statistically. The results showed that the short-term successful rate of hemostasis by TAE was 89.5% (17/19), the incidence of re-bleeding after TAE was 36.8% (7/19) and the successful rate of hemostatis by second TAE was 71.4% (5/7). It was concluded that the intra-abdominal bleeding in SAP was mainly caused by the rupture of erosive/infected pseudoaneurysm. Mostly, the broken vessels were splenic artery and gastroduodenal artery; In terms of emergence hemostatis, TAE is the most effective method. Surgical hemostasis is necessary if hemostasis by TAE is failed or re-bleeding occurs after TAE.
