Objective To explore the changes of bone mineral density and risk factors of OP in old female patients with type Ⅱ diabetes.Methods 737 cases of old female patients with type Ⅱ diabetes in Department of Endocrinology were analyzed.All patients were first divided into two groups(Group A,with OP;Group B,without OP)according to OP.Then,the changes of bone mineral density and related risk factors were analyzed with Logistic regression approach.Results In the comparison of Group A and Group B,the results are shown as follows.In Group A:ICTP(7.34±1.84)μg/L,FBG(7.12±1.14)mmol/L,BMI(22.45±2.37)kg/m2,BMD,A(62.45±17.56);InGroup B,the corresponding levels were(4.13±1.07)μg/L,(8.48±1.28)mmol/L,(15.46±6.78)mmol/L,(89.75±14.56)respectively.The resuhs presented statistical differences.(t=29.958、-14.405、16.262、-22.665,both P＜0.05).In Group A,HbAle(7.33±0.32)%,serum calcium(2.35±0.72)mmol/L,serum phosphorus(1.03±0.23)mmol/L,the corresponding values in Group B are(7.21±0.24)%,(2.42±0.34)mmol/L,(1.02±0.28)mmol/L.There sxe no statistical differences in two groups(both P＞0.05).In Group A,FN(52.50±18.40)pmol/L,UALB was(8.03 ±1.86)mg/L,Leptin was(5.14 ±1.19)μg/L;the Values in Group B were (40.70±16.34)pmol/L,(5.91±1.24)mg/L,(5.63±1.23)μg/L,The values of FN,UALB in both groups had statistical differences(t=7.469、18.515,both P＜0.05);the values of Loptin in two groups had no statistical difference(P＞0.05).Based on the incidence of OP among old female patients,the leveh of HbAlc,serum calcium,serum phosphorus,ICTP,FBG,BMI、BMD,FN,UALB,Leptin,course of disease,losing body mass,were taken as independent variables and to analyze use Logistic Regression approach.Conclusion FN,UALB,course of disease,BMI and losing body mass were the independent risk factors of OP in old female patients with type Ⅱ diabetes.

Objective To discuss the effect of the modified structure of oxygen equipment on oxygen inhalation effect of patients receiving oxygen therapy.Methods The structure of oxygen equipment was modified.and 80 patients who required oxygen therapy were divided into the modified group and the non-modified group according to odd and even number of hospital admission sequence randomly with 40 patients in each group.The modified group used the modified oxygen equipment,the non-modified group used traditional one.The differences of respiration,heart rate and blood oxygen saturation rate between the two groups before oxygen inhalation,30 minutes and 2 hours after oxygen were compared.Results There was no significant difference in the respiration,heart rate and blood oxygen saturation rate between the two groups.Conclusions The modified oxygen equipment doesn't affect the oxygen therapy effect of patients,besides,it avoids the problems of pollution and the complicated disinfection procedure of the structure of the humidifier bottle,fluid and breathing vessel of the traditional equipment.

Objective To evaluate the effect of perioperative enteral immunotrition(IMPACT) on liver regeneration in cirrhotic rats with hepatectomy. Methods Forty-eight cirrhotic rats were randomly divided into two groups: Group A, perioperative standard enteral nutrition group(n=24), receiving standard enteral nutrient NUTRISON during hepatectomy. Group B, perioperative enteral immunonutrition group(n=24), receiving enteral immunonutrient IMPACT after hepatectomy. According to the different time of taking specimens, each group was separated into four subgroups, each subgroup had six rats. The rats in the two groups received equal daily nutritional supplement intragastrically, which was 690kJ/kg per day. Before the 68% hepatectomy, the rats were fed with enteral nutrient for 8 days, and after operation were fed until the day of taking specimens. On the day before hepatectomy and 1st, 4th and 8th postoperative day(POD), MI (mitotic index) of liver cell and PCNA (proliferating cell nuclear antigen) labeling index of hepatocyte were determined. Results MI increased significantly in both group on 4th and 8th postoperative day(P

Objective To study the effect of intracerebroventricular(icv) injectionon acetylcholine(ACh) on the elecric activities of pain-related neurons in the hippocampal CA1 area of rat.Methods Trains of the electric impulses applied to the right sciatic nerve were used as noxious stimuli.The discharges of neurons were led out by extracellular recording method with glass microelectrodes.Results Icv injection of ACh(20?g/10?l) caused an decrease of the evoked discharge frequency of pain-excited neurons(PEN) and a prolongation latency as well as an increase of the evoked discharge of pain-inhibited neurons(PIN) and a shortening of inhibitory duration.Conclusion The response of pain-related neurons in hippocampal CA1 area to the noxious stimulation is weakened by icv injection of ACh,exhibiting analgesic effect.

Objective To systematically evaluate the safety of laparoscopic distal pancreatectomy (LDP) compared with open distal pancreatectomy (ODP).Methods Databases including Cochrane library,MEDLINE,EMbase,Google Scholar and Chinese National Knowledge Infrastructure were searched to enroll randomized clinical trials (RCT),controlled clinical trials (CCT) or retrospective case-control studies to compare LDP with ODP.All articles received quality assessment according to the inclusion and exclusion criteria,then the selected indices were analyzed using the Review Manager Version 5.0 software (The Cochrane Collaboration,Oxford,United Kingdom).Results 21 manuscripts with a total of 2 797 patients were enrolled.1 150 patients underwent LDP and the remaining 1 647 patients underwent ODP.In 20 studies (n =2 597),the total postoperative complication rates were 33.90％ for the LDP group versus 46.80％ for the ODP group [RR =0.76,95％ CI(0.69 ～ 0.84),P ＜ 0.01].In 8 studies (n =1 869) there was no significant difference [RR =0.51,95％ CI(0.21 ～ 1.24),P ＞0.05] in the perioperative mortality between LDP (4/703) and ODP (18/1 166).In 20 studies (n =2 757) there was no significant difference [RR =0.89,95％ CI(0.75 ～ 1.06),P ＞ 0.05] in the pancreatic fistula rate between LDP (168/1 132) and ODP (281/1 625).In 11 studies (n =1 840) the wound infection rate of LDP (3.24％) was significantly lower than ODP (10.85％) [RR =0.34,95％ CI(0.23 ～ 0.52),P ＜ 0.01].No significance was found between the two groups in the rates of pulmonary complications,peritoneal infection,urinary tract infection,postoperative bleeding,pseudocyst formation,intestinal obstruction and ascites formation between LDP and ODP.Conclusions When compared with the traditional open procedure,LDP has the advantages of significantlylower rates of postoperative complication and wound infection.There were no significant differences in postoperative mortality,and pancreatic fistula rate between LDP and ODP.This meta-analysis suggests that LDP is a safe and feasible operative method.
