Objective To explore the controlling level of fasting blood glucose(FBG) and glucosylated hemoglobin(GH) in order to stop occurrence of nephropathy in diabetic mellitus.Methods Data was collected by retrospective study,analyzed by non-conditional Logistic regression.Then the controlling levels of blood glucose and glucosylated hemoglobin were studied by regression equation.Results It was regarded that under 6.8 mmol/L of FBG and 5.9% of GH,diabetic nephropathy can be prevented;while under 6.0 mmol/L of FBG and 5.3% of GH,the onset of diabetic nephropathy was strictly controlled.Conclusion it is more important to control strictly on the threshold of fasting blood glucose and glucosylated hemoglobin for prevention of diabetic nephropathy.

In Cantharidin-poisoned rats, nicotinamide-adenine dinucletide dehydrogenase (NADHD) andcytochrome oxidase (CCO) activities of myocardi-um, stomach and intestine were observed in exper-iment histochemically. The result showed thatNADHD and CCO reaction granules were de-creased, stained weakly, and distributed sparselyin myocardium, stomach and intestine of intoxicat-ed rats as compared with the control group. Thus,from the experimental result it was considered thatcantharidin may inhibit the activities of NADHDand CCO in varving degrees.

Based on the histochemical observation ofnicotinamide adenine dinucleotide dehydrogenase(NADHD) and eytochrome oxidase (CCO) activi-ties of myocardium in cantharidine poisoned rats,furthermore, we observed the changes of these en-zymes of the myocardium cytochemically. The re-sult showed that, compared with control group, NADHD and CCO activities were inhibited afteradministration of cantharidin 1 or 2 h, and the in-hibition was found to be more obvious with poison-ing times prolonged, after 24 h, the cristae of mi-tochondria can not be distinguished, and the reac-tion products diffued into stroma to become a ho-mogeneous mass and lost their normal localization.It is indicated that cantharidin might destroy thestructure of mitochondria and interfere the activi-ties of NADHD and CCO of which both are locatedon mitochondria.

ObjectiveTo modify the technique of whole small bowel transplantation in rats to improve the survival.MethodsOne hundred and six SD rats served as donors and recipients to establish a homogeneous and orthotopic model of small bowel transplantation without fistula.Anastomosis of aorta and vein was done with three- cuff technique,the vena mesenterica superior of recipient was done under a surgical microscope.End-to-end anastomosis was performed between donor proximal small intestine and receptor jejunum,and also between the remote and receptor ascending colon.Surviving more than 3 days after surgery was defined as the operation was successful.ResultsThe operation was successfully carried out in 48 cases with the survival rate of 90.6％ (48/53).The average warm ischemic time was 0 minute,and the average cold ischemic time was(30 ±2.48)min.The survival rate( ＞7 d) was 97.9％ (47/48).ConclusionsOn the basis of three-cuff technique,the survival of SBT was greatly improved.When the vena mesenterica superior of recipient was done under a surgical microscope,the surgical training time was shortened.

Objective To establish a satisfactory lung metastasis model of human choriocarcinoma using severe combined immunedeficient(SCID)mice and explore the appropriate cell concentration for the model.Methods Forty SCID mice aged between 5-6 weeks were randomly difided into four groups.1×107 cells/ml ×0.1 ml.5×106 cells/ml×0.2 ml and 1×106 cells/ml×0.1 ml of human choriocarcinoma cells JEG-3 were respectively injected in SCID mice of experimental groups by lateral tail vein,the remain group was assigned to the control group.The status and weisht of mice were observed every three days.When these mice were being dying.the size and the number of the lesions of lung metastasis in every mouse were inspected with Micro CT.After Micro CT inspection,the SCID mice were executed dissected to note whether there were tumors on all organ surfaces witll naked eyes.then made pathological sections from the metastaticfoci of fresh lung tissues,and cultured primarily cells and purified cells and passaged cells isolated from the same metastastic foci.The pathological sections were observed under the microscope.The special antigen human chorionic gonadotropin-beta subunit(β-hCG)of the choriocareinoma cells was immunohistochemically detected in the pathological sections and the cells out of cultured primarily cells.The chromosomes of the cells out of cultured primarily cells were analysed.Results Of the group inoeutated 1×107 cells/ml×0.1 ml.all mice died when inoculating.In the group of 5×106 cells/ml×0.2 ml,when inoculating, 3 mice died; the remain 7 mice were being dying on ( 18. 0 ±2. 0) days after injection. 5 of them, there were 1 - 3 lesions of lung metastasis after Micro CT inspection in each mice, and the diameter of the tumors lesions reached 1.5 - 3.5 ram, which was choriocarcinoma confirmed by pathological sections.The special antigen β-hCG was detected by immunohistoehemical method in the pathological sections of pulmonary tissue with tumor and in the cells, which were purified and passaged from being cultured primarily cells isolated from metastastic foci of fresh lung tissues from the SCID mice. The chromosome numbers of these cells out of cultured primarily ceils were variety from 19 to 128, and medal numbers were variety from 70 to 79. Conclusions We successfully established the lung metastatic model of human choriocarcinoma in SCID mice by injecting JEG-3 cells into lateral tail vein, of which 5 × 106 cells/ml × 0. 2 ml is the suitable concentration and volume for the model.

Objective To investigate the impact of nutritional risk of preoperative patients with different parts of colorectal cancer. Methods 385 cases of surgical patients diagnosed with colorectal cancer were selected in the retrospective study in April 2008 to March 2009, Gastrointestinal Surgery Center of West China Hospital in Sichuan University. Patients were divided into the right colon cancer group, the left colon cancer group, the rectal cancer group, using internationally recognized NRS- 2002 Scale and serum nutrition indicators to assess their preoperative nutrition. Results NRS-2002 score in the right colon cancer group showed higher than the left colon and rectal cancer group, but no statistical difference between the latter two rates; serum concentrations of HGB, TP, ALB, A/G were lower in the right colon cancer group than the other two groups, but the concentrations of ALT, AST, Ca2+, PO43-showed no statistical difference among three groups. Conclusions The proximal colon (right colon cancer) were more susceptible to the risk of preoperative malnutrition, the patients with different parts of colorectal cancer should be given to the corresponding preoperative nutritional assessment and nutritional support.

Objective To understand enterprises' demands for health management. Methods Self-designed questionnaires were distributed to senior managing directors from 104 enterprises in Jingzhou City of Hubei Province. The counting data were expressed as percentage or accumulated percentage. Results The main health problems in Jingzhou City were chronic diseases (28.4%), unhealthy behaviors (40. 1% ), occupational diseases ( 22. 8% ), and enviromental pollution ( 8.7% ). Health service needs of enterprises included health speeches (37.2%),health consultation (53.8%),medical report interpretation (43. 2% ), nutrition intake guidance ( 10. 5% ), and green passage medical treatment ( 14. 7% ).Conclusion All the enterprises show strong needs for health management. Establishing appropriate health management model may have better prospects.

Twenty-three patients with uniloculated deep neck abscesses (UDNA),in whom the antibiotic therapy failed and CT-guided percutaneous catheter drainage (PCD) was performed from January 2005 to June 2015,were included in the study.Catheter placement was carried out using Trocar technique in all cases.Open surgical drainage was performed when PCD procedures failed.The abscess was completely drained and open surgical drainage was avoided in 19 cases (83％);the surgical drainage was performed because of muhiple internal septation in 3 (13％) case,and 1 (4％) case died from uremia.In this series the technical success rate and clinical success rate of PCD were 96％ (22/23) and 83％ (19/23),respectively.All patients were followed-up by CT scan.No other complications and no mortality occurred during the procedure,while postoperative pneumatosis developed in 1 case.CT-guided PDC is a safe and highly effective low-cost procedure for the treatment of patients with UDNA who failed medical therapy,it may be considered as an alternative to open surgery.

Objective To investigate the effect of acute normovolemic hemodilution (ANH) combined with controlled hypotension (CH) on the extravascular lung water (EVLW) and oxygenation in elderly orthopaedic surgery patients.Methods Forty-five elderly orthopaedics surgery patients,23 males,22 females,aged 65-75 years old,ASA grade Ⅰ or Ⅱ,were randomly divided into 3 groups (n=15 each).Group A,served as control,received regular routine transfusion and intraoperative crystalloid fluids and colloidal liquid to add volume.Group B,namely ANH group,received normovolemic hemodilution till Hct reaching 30% after induction of anesthesia.Group C,ANH combined with CH group,received ANH with Hct reaching 30% after induction of anesthesia,and the patients were continuously pumped nitroglycerin combined with esmolol for controlled hypotension.The target mean arterial pressure controlled and cut by 30% below the basic value.We collected arterial blood for blood gas analysis at 5 points: before before induction of anesthesia (T1),immediately after ANH (T2),30 min after ANH (T3),30 min after CH (T4),immediately after surgery (T5).Meanwhile the MAP,HR,PaO2,SpO2,Hct,HCO3-,pH,cardiac index (CI),stroke volume variation (SVV),stroke volume index (SVI),extravascular lung water index (EVLWI) and intrathoracic blood volume index (ITBVI) were recorded.Blood loss,urine output after surgery and the operation time were also recorded.Results The volumes of autoblood removed had no significant difference between group B and group C,and no autoblood was removed in group A.The volume of blood loss in group C was significantly less than that in group A and group B (P<0.05).Six cases in group A,one case in group B and none in group C needed homologous allogeneic blood transfusion.Compared with T1,MAP,HR,CI,SVI and Hct were significantly decreased at T2-T5 (P<0.05),but all those are stable in the normal range.Compared with T1,SVV was significantly decreased at T2-T4 (P<0.05).Compared with T1,ITBVI,PaO2 and SpO2 were increased at T2-T5 (P<0.05),but all those are stable in the normal range.CI and SVI at T2 in group A was significantly lower than that in group B and C.Compared with group A and B,MAP at T4 in group C were significantly decreased and SVV at T4 in group C were significantly increased(P<0.05).Urine output,the operation time,EVLWI,HCO3-and pH in three groups had no significant difference.Conclusion Acute normovolemic hemodilution combined with controlled hypotension has an effect of saving blood in elderly patients,without any influence on the extravascular lung water and oxygenation,which can be used safely in elderly patients which they are monitored.
