Objective To observe the feasibility of phase-rectified signal averaging applied for the evaluation of automatic nervous system activity in general anesthesia.Methods Forty-seven fe-males and 63 males aged 18-65 years,ASA falling into category Ⅰ or Ⅱ,scheduled for oral maxillo-facial surgery under general anesthesia were selected.The heart rate variability(HRV)signal was re-corded by Powerlab throughout the operation,and then it was sectioned into three segments with 5 minutes:pre-anesthesia(T0 ),means the waking state before the operation;intra-anesthesia(T1 ),the period of operation in 25-30 min;post-anesthesia(T2 ),the consciousness recovery state in the end of the operation.All indicators of HRV analysis was calculated in the time domain.SpO 2 ,MAP and BIS were recorded synchronously in the three periods.Results Compared with T0 ,DC, RMSSD, SDNN,SD1,SD2,logTP,logLF,logHF were significantly lower at T1 and T2 (P <0.05).In con-trast to T1 ,HR,MAP and BIS were significantly higher at T2 (P <0.05 ),DC,RMSSD,SDNN, SD1,SD2,logTP,logLF,logHF were significantly increased at T2 (P <0.05 ).There was positive relation between DC and RMSSD,SD1,logHF (r =0.905,0.909,0.932,respectively,P <0.01). Conclusion As 5 min-DC could indicate the character of PRSA,especially its specificity in showing vagus nerves activities,it is feasible that DC is used to observe the autonomic nerve activity intra op-eration.

OBJECTIVE:To prepare Baicalin proliposomes (PBA) containing sodium deoxycholate (SD) with optimized for-mulation,and to study pharmacokinetics of it in rats in vivo. METHODS:PBA were prepared by spray drying method. Response surface method based on Box-behnken design was adopted to optimize the formulation of PBA with the amount of HSPC,cholester-ol and SD as factors using entrapment efficiency of PBA as index. The particle size,morphology,leakage rate and stability of the optimal PBA were evaluated along with the pharmacokinetics of it(compared to raw materials)in rats after ig administration of 15 mg/kg. RESULTS:The optimal formulation of PBA was that the amounts of baicalin,HSPC,cholesterol and SD were 100,214, 68 and 53 mg,respectively;the predicted and practical values of entrapment efficiency were 86.42% and 84.32%,respectively, and particle size of the optimal PBA was 358.4 nm. The leakage rate of reconstituted liposomes was low and the stability of PBA was good. Compared with baicalin raw material,t1/2,tmax,MRT,cmax and AUC0-t of PBA were all increased significantly(P<0.05 or P<0.01 or P<0.001). CONCLUSIONS:PBA were prepared successfully using the spray drying method. This method is simple and easy,and the optimized formulation is feasible and can improve the oral bioavailability of baicalin.

Objective To compare the effects of neutral posture training (NPT) and gas resistance training on balance and motor func-tion in stroke patients. Methods From June, 2014 to February, 2016, 44 hemiplegic patients were randomly divided into control group (n=22) and experimental group (n=22). The control group received conventional decubitus trunk muscle training and sitting gas resistance train-ing. The experimental group received NPT. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), Fugl-Meyer Assessment-Lower Extremities (FMA-LE), and Berg Balance Scale (BBS) before and after training. Results There was no significant differ-ence in the scores of FMA-UE, FMA-LE and BBS between two groups (t<0.962, P>0.05). The scores significantly increased after training in both groups (t>12.248, P<0.001), and were higher in the experimental group than in the control group (t>1.972, P<0.05). Conclusion The NPT could improve the motor and balance function of stroke patients, rather than gas resistance training.

Objective Serologic proteome analysis method (SERPA) was used to compare the different of the serum proteins between normal and pancreatic cancer patients' serum, and to find a new specific pancreatic cancer marker. Methods HPLC was used to eliminate albumin from the serum, two-dimensional electrophoresis was used to separate the proteins. After imaging collection and analysis, the different proteins between pancreatic cancer and normal subjects were cut for mass spectrometry. Results Four discrepancy proteins were obtained. Guanylate cyclase-activating protein 2 was highly expressed in normal serum but not pancreatic cancer. Hp2-alpha, transthyretin and KIAA1018 protein were highly expressed in cancer patients'serum but not normal people. Conclusions KIAA1018 may become a promising tumor marker for screening and early diagnosis of pancreatic cancer.

The purpose of this study is to discuss the feasibility of establishing capsaicin pain model and the possibility to evaluate different degrees of pain by the heart rate variability (HRV). It also aims to investigate the changes of autonomic nervous activity of volunteers during the process of pain caused by capsaicin. A total of 30 volunteers were selected, who were physically and mentally healthy, into the study. To assess the effects of capsaicin on the healthy volunteers, we recorded the Visual Analogue Scale (VAS) scores after the capsaicin stimulus. Additionally, the electrocardiogram signals and HRV analysis index before and after stimulating were also recorded, respectively. More specifically, the HRV analysis indexes included the time domain index, the frequency domain index, and the nonlinear analysis index. The results demonstrated that the activity of the autonomic nerves was enhanced in the process of capsaicin stimulus, especially for the sympathetic nerve, which exhibited a significantly differences in HRV. In conclusion, the degree of pain can be reflected by the HRV. It is feasible to establish a capsaicin pain model. And in further experiments, HRV analysis could be used as a reference index for quantitative evaluation of pain.

OBJECTIVETo observe the efficacy of He-wei Jie-gu (Chinese characters) decoction on femoral intertrochanteric fractures after internal fixation in elderly.

METHODSFrom January 2010 to January 2012, 90 elderly patients with osteoporotic intertrochanteric fracture were randomly divided into two groups. The patients in experimental group were treated with open reduction and internal fixation, He-wei Jie-gu decoction and Caltrate D in oral, including 18 males and 27 females with an average age of (77.8±11.3) years old ranging from 65 to 89 years old;the time from injured to operation was 2 to 9 days with an average of (6.6±2.1) days; according to Evans-Jensen classification, 17 cases were in type I, 8 in type II, 15 in type III, 3 in type IV, 2 in type V. Meanwhile, the patients in control group were treated with open reduction and internal fixation, Caltrate D in oral, including 16 males and 29 females with an average age of (81.2±9.6) years old ranging from 67 to 91 years old; the time from injury to operation was 2 to 10 days with an average of (6.8±2.6) days; according to Evans-Jensen classification, 15 cases were in type I, 10 in type II, 14 in type III, 4 in type W, 2 in type V. The VAS score, hip BMD value before and after treatment, fracture healing and the Harris function score after operation were recorded and compared.

RESULTSAll patients were followed up from 3 to 9 months with an average of (5.6±2.8) months. Compared with the control group, the VAS score of the experimental group had an obviously reduction (F=98.138, P<0.01) after treatment; the hip BMD value at 3 months after treatment in the experimental group was higher than that of the control group (P<0.05); the fracture healing rate of the experimental group was higher than that of the control group (P<0.05); Harris score in 3 months of follow-up in the experimental group was higher than that of the control group (t=2.542, P<0.05); all the differences between two groups were statistically significant (P<0.05).

CONCLUSIONHe-wei Jie-gu decoction can reduce postoperative pain and increase bone mineral density after internal fixation of femoral intertrochanteric fracture in elderly, promote the fracture healing and functional recovery in the hip joint.

A series of novel tetrahydrocarboline derivatives was designed and synthesized in order to discover more potent peroxisome proliferator-activated receptor (PPAR) alpha/gamma dual regulators. The structures of these compounds were confirmed by 1H NMR and HR-MS; their PPAR-regulating activities were evaluated in vitro. Compounds 6h, 6n, 6p and 6q exhibited more potent PPARalpha agonistic activities than the control drug WY14643, while compounds 60, 6g, 6i and 6q exhibited more potent PPARgamma agonistic activities than the control drug rosiglitazone. Compound 6q was discovered as a potent PPARalpha/gamma dual agonist and deserves further investigation.
