BACKGROUND: Geshu (BL 17) is one of eight influential points of blood, acting on tonifying blood, nourishing blood, activating blood circulation and resolving stasis.OBJECTIVE: To explore the effect of Geshu (BL 17) on activating blood circulation and resolving stasis in blood stagnation syndrome with acupuncture.DESIGN: Randomized controlled and normal controlled observations were designed.SETTING: Union Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology.PARTICIPANTS: Totally 65 cases of blood stagnation syndrome were selected from inpatients in Department of Acupuncture and Moxibustion in Union Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology.METHODS: Totally 65 cases were randomized into experiment group (33cases) and the control (32 cases). In the control, the patent Chinese drug,longxuejie was administrated orally for activating blood circulation and resolving stasis, 4 tablets/time, 3 times/day, 15 days made 1 course of treatment. In experiment group, Geshu (BL 17) was localized bilaterally; after routine sterilization on the points, a filiform needle, 25 mm in length was inserted and manipulated with even technique after arrival of qi for 5 minutes. In 15 minutes of needle retaining, the needle was manipulated for another 5 minutes and retained for 10 minutes, and then, the needle was withdrawn. The treatment was given once a day. Radioimmunoassay (RIA)was applied to determine the levels of 6-K-P and thromboxane B2 (TXB2)in plasma. Criteria on clinical therapeutic effects: Being cured is determined by slight red tongue, retarded and forceful pulse, disappearance of limb pain, skin and mucosal ecchymosis and dysmenorrhea, basic recovery of motor function in hemiplegia and disappearance of numbness. Being effective is by dark red tongue, slightly hesitant pulse, alleviation of limb pain, reducing of skin and mucosal ecchymosis, alleviation of dysmenorrhea, partial recovery of motor function in hemiplegia and alleviation of numbness. No effect is by none of any change of clinical symptoms in comparison before and after treatment.MAIN OUTCOME MEASURES: ① Observation of therapeutic effects between two groups. ② Observation of plasma 6-K-P and TXB2 levels and 6-K-P/TXB2RESULTS: Totally 65 cases were all in the result analysis. ① Observation of therapeutic effects between two groups: The therapeutic effect in experiment group was higher remarkably than that in the control [be cured:(15,10); be effective: (13,11)]. ② Comparison of plasma 6-K-P levels: In experiment group, it was higher remarkably after treatment compared with that before treatment [(159.28±16.48), (117.25±16.47) μg/L, P ＜ 0.05]. In the control, it was higher remarkably after treatment compared with that before treatment [(133.51±13.97), (114.64±16.39) μg/L, P ＜ 0.05]. ③Comparison of plasma TXB2 level: In experiment group, it was lower remarkably after treatment compared with that before treatment [(98.21±11.38), (110.45±1067) μg/L, P ＜ 0.05]. In the control, it was lower remarkably after treatment compared with that before treatment [(101.15 ±12.14), (109.21±11.58) μg/L, P ＜ 0.05]. ④ Plasma 6-K-P/TXB2: In experiment group, it was higher remarkably after treatment compared with that before treatment (1.621±0.203, 1.101±0.316, P ＜ 0.05). In the control,it was higher remarkably after treatment compared with that before treatment (1.322±0.216, 1.234±0.305, P ＜ 0.05).CONCLUSION: Acupuncture on Geshu (BL 17) increases 6-K-P level and 6-K-P/TXB2 and reduces TXB2 level. It is explained that acupuncture on Geshu (BL 17) regulates imbalance of PGI2-TXA2 system in blood stagnation syndrome so that the blood circulation is activated and stasis is resolved.

Objective To investigate the construction and significance of in vivo pelvis and abdominal-pelvic arterial vascular network in digital three-dimensional (3D) model for uterine artery embolization (UAE) in the application of surgical approach planning based on computerized tomographic angiography(CTA).Methods A series of digital imaging and communications in medicine 3.0 (Dicom 3.0) were obtained from a woman with myoma of uterus by CTA scanning.Then the software Mimics Version 10.01 was used to construct the pelvic and the arterial vascular network 3D model.Results The digital model could clearly display the abdominal aorta,bilateral common iliac arteries,left and right external iliac artery,internal iliac artery and its branches around the stage ; the right uterine artery emitted in the inferior gluteal artery opening below 15.91 mm,the left uterine artery in inferior gluteal artery below the opening of 15.21 mm,the adjacent artery of internal pudendal artery.At the same time,the artery length and angle of bifurcation were accurately measured.The bifurcation angle of abdominal aorta in fifth lumbar vertebral body edge,was 66.58°,the bifurcation angle of right internal iliac artery was 46.23°,the length of right common iliac artery was 51.43 mm,the bifurcation angle between left and external internal iliac artery was 36.45°,the length of left common iliac artery and 67.50 mm.According to the preoperative approach planning,guided wire across the inferior gluteal artery to the lower 15.00 mm and rotating digital subtraction angiography(DSA) tube,could clearly display the uterine artery opening outward by rotating guide wire,which was relatively easy to enter the uterine artery.Conclusion The female pelvic arterial network model in vivo could be successfully constructed by using Mimics Version 10.01 software with database collected through CTA,which may contribute to the materialization of digital models and be used for preoperative surgical simulator.

Objective To explore whether the peritoneal cooling was better than other cooling methods on protection neuron damage of the hippocampus CA1 after cardiopulmonary resuscitation (CPR) in New Zealand rabbits.Methods Forty eight adult New Zealand rabbits were induced ventricular fibrillation by AC current and were resuscitated after cardiac arrest for 5 minutes.The rabbits were randomly divided into four groups according to the way of cooling methods,nomothermia group ( NT),peritoneal cooling group (PC),surface cooling group (SC) and local cooling group (LC).The changes of tympanic membrane temperature were recorded in each animal and blood plasma concentrations of electrolyte were tested in each group at different time points after restore of spontaneous circulation (ROSC).Brain tissue were removed,the numbers of vigorous and apoptotic neurons in the hippocampus CA1 area were counted after ROSC at 72h.One-way ANOVA or Mann-Whitney rank was used to determine the statistical significance between two groups.LSD-t test for multiple comparisons,R × C test for ROSC comparisons,a two-tailed value of P ＜0.05 was considered statistically significant. Results Hypothermia was rapidly induced in PC after ROSC,and the time of arriving at target temperature was (26 ±7) min in PC,(60 ±9) min in SC,(69 ± 12) min in LC respectively; in the maintain hypothermia period,the tympanic membrane temperature was maintained at 33～ 35 ℃ in each group exception nomothermia group (NT).There were no differences with main electrolyte,acid-abase liquid balance and renal function between each group at each time point after ROSC.The numbers of vigorous neurons in hippocampus CA1 area were ( 37.07 ± 6.43 ) /40 × in NT group,(35.13 ± 6.97) /40 × in LC group,(55.76 ± 10.13 ) /40 × in PC group,and (50.70 ± 7.38 ) /40 × in SC group (PC:NT,P＜0.01,SC:NT,P＜0.01,PC:SC,P=0.043,PC:LC,P＜0.01,LC:NT,P=0.52).The numbers of apoptotic neurons were (44.07 ±6.09) /40 × in NT group,(29.88 ±4.81 ) /40× in PC group,( 33.55 ± 5.67 ) /40 × in SC group and ( 42.27 ± 5.20 ) /40 × in LC group respectively (PC:NT,P ＜0.01,SC:NT,P ＜0.01,PC:LC,P ＜0.01,SC:LC,P ＜0.01,PC:SC,P=0.026,LC:NT,P =0.364 ).Conclusions The new peritoneal cooling method could rapidly induce and maintain hypothermia,and it had better protections on neurons in hippocampus CA1 than surface cooling and local cooling method after ROSC in New Zealand rabbits.

A method for simultaneous determination of 20 Perfluorinated alkyl substances ( PFAS) in animal liver using QuEChERs and HPLC_MS/MS technique was developed. The samples were extracted with 0. 1%hydrochloric acetonitrile and cleaned up with C18 , N_Propylethylendiamine ( PSA ) and graphitized carbon blacks ( GCB ) . The analytes were separated by a reversed phase C18 column and gradiently eluted with a mixed solution of 5 mmol/L ammonium acetate methanol and 5 mmol/L ammonium acetate. The samples were quantified using isotope internal standard and external standard with the matrix matched standard calibration curve method. Good linearity was obtained for all the 20 PFAS at the concentration of 0. 1-10 μg/L with the linear correlation coefficients more than 0. 9995. The limits of detection (LOD) and the limits of quantification ( LOQ) for PFAS were 0. 05-0. 2 μg/kg and 0. 4-0. 5 μg/kg, respectively. The recoveries at three different concentration levels ( 0 . 5 , 2 and 5 μg/kg ) were in the range of 70 . 3% -108 . 1%. The repeatability expressed as relative standard deviations (RSD) was ranged from 2. 1% to 11. 9% (n=6).

Objective To investigate whether Ulinastatin (UTI) would minimize the systemic inflammatory response,lessen cardiac dysfunction and protect neurons against injury in hippocampus CA1area after restoration of spontaneous circulation (ROSC). Methods Animal models of cardiac arrest were established in 24 New Zealand rabbits,and those animals were randomly (random number) divided into control group and UTI treated group after ROSC.Changes in the levels of plasma inflammatory cytokines TNF-α and IL-6 were assayed before cardiac arrest and 4,8,12 and 16 hours after ROSC.Cardiac function including FS,EF and E/A were observed with ultrasonography before cardiac arrest and 4,8,12 and 16hours after ROSC,and viable and apoptotic neurons in hippocampus CA1 area and infiltrations of MPO positive cells in myocardium,cerebrum,liver,kidney and intestine were counted 72 hours after ROSC.The t-test or Mann-Whitney rank sum test was used to verify the specified theoretical distribution functions of the biomarkers tested by Kolmogorov-Smirnov test,POST HOC test was used for the multiple comparisons,and Pearson correlation analysis was used to investigate the correlation between inflammatory cytokines and cardiac function. Results The levels of TNF-α and IL-6 in UTI group were lower than those in control group as those data got 4,8,12 and 16 hours after ROSC (P ＜0.05).EF and E/A in UTI treated group were higher than those in the control group as those data got 4,8,12 hours after ROSC.FS values obtained 4 h and 8 hours after ROSC were higher in UTI group than those in control group ( P ＜ 0.05 ).The Pearson correlation analysis showed that the levels of TNF-α and IL-6 significantly correlated with EF after ROSC.The number of viable neurons in CA1 area of control group was ( 13.22 ± 0.97) which was lower than that in UTI group ( 16.89 ± 1.45 ) ( P =0.003 ),while the number of apoptotic neurons in hippocampus CA1 area was higher in control group than that in UTI group (15.67 ± 1.37) vs.(13.67 ± 1.03 ) (P =0.019).The numbers of MPO positive cells were significantly lower in liver,kidney and intestine in group UTI than those in control group. Conclusions UTI could inhibit the infiltration of MPO positive cells in liver,kidney and intestine,decreasing the levels of TNF-α and IL-6 in plasma,in turn lessening cardiac dysfunction and protecting neurons from injury in hippocampus CA1 area after ROSC of New Zealand rabbits.

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.

Objective To establish a new model of cardiac arrest (CA) in rats by transcutaneous electrical epicardium stimulation. Method Two acupuncture needles connected to the anode and cathode of a stimulator were transcutaneously inserted into the epicardium as electrodes. The stimulating current was steered to the epicardium and the stimulation was maintained for 3 minutes to induce CA. Cardiopulmonary resuscitation (CPR) was performed at 6 minutes after a period of nonintervention. Results The success rate of induction was 12/20 at the current intensity of 1 mA; and reached 20/20 when the current intensity was increased to 2 mA. The average time from the electrical stimulation to CA induction was (5. 10 ± 2. 81) seconds. When the electrical stimulation stopped, 18/20 rats had ventricular fibrillation and 2/20 rats had pulseless electrical activity. CPR was performed for averagely 207.4 ( ± 148.8) seconds. The restoration of spontaneous circulation was 20/20. The death rate within 4 hours after CA was 5/20, and the 72-hour survival rate was 10/20. There were only two cases of complications, a minor muscle contraction and a minor lung lobe injury. Conclusions The model of CA in rats induced by transcutaneous electrical epicardium stimulation is a stable model that requires low-intensity current and has fewer complications.

BACKGROUND:CT-guided percutaneous intervention and rehabilitation techniques are both classic programs for diagnosis and treatment of lumbar disc herniation. Is the combination of CT-guided percutaneous intervention and rehabilitation techniques preferential y used for treatment of lumbar disc herniation?
OBJECTIVE:To evaluate the curative effect of CT-guided interventional injection combined with rehabilitation integration treatment for lumbar disc herniation and to analyze prognostic factors.
METHODS:Eighty-eight patients with lumbar disc herniation were subjected to CT-guided interventional injection combined with rehabilitation integration treatment from May 2010 to May 2013. Injection medicine consisted of betamethasone, tanshinone Ⅱ A sulfonate, neurotropin, normal saline and iohexol. Rehabilitation integration treatment included traction, manipulation, acupuncture, transcutaneous electrical nerve stimulation and thermal magnon. Macnab criteria and Chinese version of Oswestry low back pain disability questionnaire were used to assess the curative effects in comparison with the 112 patients receiving only CT-guided interventional injection that were reported previously. The prognostic factors, such as age, disease course time and herniation type of target segment were testified by correlation analysis.
RESULTS AND CONCLUSION:Total y 77 patients were completely fol owed up for 1 year. There were excellent outcomes in 64 cases, while favorable outcomes in 7 cases, fair outcomes in 5 case, poor outcome in 1 case, with a better outcome rate of 92%.There was a significantly decreased trend in Oswestry disability Index scores at 1, 6, 12 months during the fol ow-ups (P<0.01). No severe complications occurred in al the included patients. The curative effects were improved in term of better outcomes rate compared with the 112 patients receiving only CT-guided interventional injection, but there was no significant difference (P>0.05). The young group (≤ 45 years) had better outcomes than the older group (>45 years;P<0.01). In addition, disease course time and herniation type of target segment were not statistical y significant risk factors predicting clinical results (P>0.05). These findings indicate that CT-guided interventional injection combined with rehabilitation integration treatment could relieve lower back pain and radical leg pain effectively and decrease life disability level.
