Objective To determine the plasma concentrations and pharmacodynamics of fentanyl and nerphine used in postoperative epidural or intravenous patient-controlled analgesia (PCEA,PCIA) .Methods Sixty ASA Ⅰ - Ⅱ patients (36 male, 24 female), aged 18-25 yr undergoing elective major operation were randomly divided into 3 groups : group Ⅰ received PCEA with 0.13 % bupivacaine + fentanyl 2?g?ml-1 (n = 20) ; groupⅡ received PCEA with 0.13 % bupivacaine + morphine 0.08 mg? ml-1 ( n = 20); group Ⅲ received PCIA with morphine 0.5 mg ? ml-1 ( n = 20). In group Ⅰ and Ⅱ the background infusion rate was 4 ml ? h-1 , PCA bolus dose 2 ml and lock-out interval 20 min, while in group Ⅲ the back ground infusion rate was 1 ml?h-1 , PCA bolus dose 2 ml and lock-out interval 6 min. PCA was maintained for 48 h in all three groups. The vital signs, analgesic effect (VAS, VRS) and side-effects were recorded and venous blood samples were taken for determination of plasma fentanyl and morphine concentrations at 4 h, 24 h and 48 h after PCA was commenced. Results The demographic data were comparable among the three groups. There was no significant difference in MAP, HR and RR during PCA among the three groups. The analgesia was satisfactory in all three groups and no other analgesic was used during PCA. The rate of excellent analgesia ranged between 80%-85 % . The incidences of side-effects were higher in group Ⅱ and Ⅲ as compared with those in group Ⅰ . The volume of epidural PCA solution administered in 48 h was significantly larger in group Ⅰ than that in group Ⅱ( P

In TCM,sui is divided into brain,spinal cord and bone marrow,etc.They are related to each other closely,stem from the kidney essence and are all connected with sea of sui,which is called fan-sui relation.Recent researches demonstrated that not only brain but also other sui can vary before or after brain damage,which may be a predictor of brain disease,or played an important role in the recovery of brain function.These achievements proved the possibility of fan-sui relation.Further research on the biological mechanism and application of fan-sui relation could:reveal the essence of 'kidney storing essence and generating sui'in TCM better and develop the new idea of the pathological mechanism of brain diseases;enhance preventive consciousness and construct the new preventive system of brain diseases characterized by TCM;help finding new methods or appropriately combine current methods to treat brain diseases.The new viewpoint can provide a chance to develop a new research field of brain diseases and improve the preventive and treatment system of brain diseases.

Objectives: The research is designed to study the accuracy and characteristics of diagnostic methods for estimating the expansive type of gastric cancer in normal clinical practice, and to evaluate the clinical significance of this estimation. Methods: Preoperative Borrmann classifications of gastric cancer were diagnosed by endoscopies, barium studies and computed tomographies. The results were compared with Borrmann classifications from surgical specimens. Results:The diagnostic accuracy of endoscopy in small gastric cancers was better than that in large gastric cancers. The diagnostic accuracy of CT for type Ⅰ and Ⅳ, which have more obvious gross characteristics, was better, and for type Ⅱ and type Ⅲ, which need to be differentiated by local characteristics such as morphologic appearances of ulcers, was worse. The barium study estimated the expansive type of gastric cancer according to borders of tumors, characteristics of ulcers and whole figure, However, it was difficult to observe detailed changes. Conclusions: To improve the veracity of preoperative diagnosis for the expansive type of gastric cancer requires integrative use of endoscopies, barium studies and computed tomographies. The diagnosis of biological characteristics of gastric cancer reflects its quality, and the diagnosis of aggressive degree reflects its quantity. Only with the diagnosis of these two aspects, can we estimate the clinical pathological process of the gastric cancer completely and comprehensively, so as to select the most reasonable and desirable treatment.

Objective:To investigate the role of apoptosis-associated speck-like protein(ASC) in non-apoptotic,non-necrotic cell death of neutrophils induced by ONO-AE-248.Methods:The morphological changes of neutrophil nuclei and DNA fragmentation of the cells were examined by confocal microscopy and terminal-deoxynucleotidyl transferase mediated nick end labeling(TUNEL).Neutrophils were stimulated with medium alone,LPS,TNF-? or ONO-AE248 respectively.Then expression of ASC was detected by Western blot.Results:ONO-AE-248-induced neutrophil death was negative in TUNEL assay.Western blot showed that the expression of ASC protein was down-regulated by ONO-AE-248.Conclusion:The DNA degradation of the neutrophils when stimulated by ONO-AE-248 is probably different from that of the typical apoptosis.ASC might be a crosslink point between the ONO-AE-248-induced neutrophil death and spontaneous apoptosis of neutrophils.

Objective To discuss the relevance of serum visfatin(VF), lipoprotein-a(LP-a) and homocysteine(HCY) in diabetic nephropathy (DN). Methods 168 patients with diabetes were selected from October 2011 to July 2015 in our Hospital.According to whether associated with kidney disease were divided into without nephropathy group (82 cases) and nephropathy group (86 cases),on the basis of urinary albumin excretion rate (UAER), nephropathy group were divided into low volume nephropathy group (UAER≤300 mg/24 h, 58 cases) and high volume nephropathy group(UAER>300 mg/24 h, 48cases),at the same time,a medical health personnel 30 cases were chosen as normal group, enzyme-linked immunosorbent method was used to detect the serum VF, LP-a, HCY levels, Pearson correlation analysis was used to analyse the relationship between UAER and serum VF, LP-a, HCY levels.Results The serum LP-a in nephropathy group was significantly higher than that of without nephropathy group and normal group, the serum LP-a, HCY in high volume nephropathy group was significantly higher than the low volume nephropathy group, the difference was statistically significant (P<0.05);the serum VF level in high volume nephropathy group>low volume nephropathy group>without nephropathy group>normal group ( P<0.05 );Pearson correlation analysis showed that, UAER were positively correlated with LP-a(r=5.013,P<0.05),VF(r=5.864,P<0.05),HCY(r=7.246,P<0.05) levels in serum.Conclusion The serum VF, LP-a, HCY levels is associated with the development of DN, and it is associated to patients with renal function changes.It is helpful to the physician monitoring disease progression in patients with DN via detecting the levels of VF, LP-a and HCY.
