To observe the changes in content of monoamine neurotransmitters in the serum of rhesus macaques, and explore the role of serum monoamine neurotransmitters in premenstrual syndrome (PMS) and liver-qi depression induced by anger-in emotion.

To explore the effective ingredients and mechanism of Ligusticum wallichii in treating brain ischemia. Four brain ischemia-related target proteins were selected in the joint screening for the 45 component in L. wallichii reported in literatures based on molecular docking by reference to the corresponding drugs in the market. According to the docking results, multiple components in L. wallichii, such as phthalides, were superior to the corresponding drugs in the market, suggesting that they may be the major effective components in L. wallichii for treating brain ischemia. The method can be used to study the material base and molecular mechanism of traditional Chinese medicines.

Action mechanism and material base of compound Danshen dripping pills in treatment of carotid atherosclerosis were discussed based on gene expression profile and molecular fingerprint in this paper. First, gene expression profiles of atherosclerotic carotid artery tissues and histologically normal tissues in human body were collected, and were screened using significance analysis of microarray (SAM) to screen out differential gene expressions; then differential genes were analyzed by Gene Ontology (GO) analysis and KEGG pathway analysis; to avoid some genes with non-outstanding differential expression but biologically importance, Gene Set Enrichment Analysis (GSEA) were performed, and 7 chemical ingredients with higher negative enrichment score were obtained by Cmap method, implying that they could reversely regulate the gene expression profiles of pathological tissues; and last, based on the hypotheses that similar structures have similar activities, 336 ingredients of compound Danshen dripping pills were compared with 7 drug molecules in 2D molecular fingerprints method. The results showed that 147 differential genes including 60 up-regulated genes and 87 down regulated genes were screened out by SAM. And in GO analysis, Biological Process ( BP) is mainly concerned with biological adhesion, response to wounding and inflammatory response; Cellular Component (CC) is mainly concerned with extracellular region, extracellular space and plasma membrane; while Molecular Function (MF) is mainly concerned with antigen binding, metalloendopeptidase activity and peptide binding. KEGG pathway analysis is mainly concerned with JAK-STAT, RIG-I like receptor and PPAR signaling pathway. There were 10 compounds, such as hexadecane, with Tanimoto coefficients greater than 0.85, which implied that they may be the active ingredients (AIs) of compound Danshen dripping pills in treatment of carotid atherosclerosis (CAs). The present method can be applied to the research on material base and molecular action mechanism of TCM.

ObjectiveTo study the relationship between 18F-FDG uptake and tumor cell density,glucose transporter expression,cellular proliferation and angiogenesis before and after radiotherapy in C6 glioma rats.MethodsThirty C6 glioma-bearing male SD rats were randomly divided into three groups:A,B and C ( 10 rats in each group).Two weeks later,18F-FDG PET/CT was performed in group A.In groups B and C,18 F-FDG PET/CT was performed at 48 h and 1 week after radiotherapy,respectively.The ratio of SUVmax of tumor to muscle (T/M) was calculated.HE staining,immunohistochemical staining and Western blot were used to measure tumor cell density,Ki67 labeling index ( LI),microvessel density ( MVD),Glut-1 and VEGF expression quantitatively.The one-way analysis of variance and bivariate correlation analysis were used to compare the changes of each indicator and evaluate the correlation between T/M and biological indicators,respectively.Results Significant differences of T/M,tumor cell density,Ki67 LI,MVD,Glut-1 and VEGF among groups A,B and C were observed ( F =6.77,60.66,104.56,95.49,9.13,24.48,respectively,all P ＜0.05).Least significant difference (LSD) test showed that there was no significant difference between group A and B in T/M,tumor cell density and Ki67 LI ( 10.86 ± 3.31,730.50 ± 78.93,20.02 ± 2.14 vs 9.23 ± 4.56,672.70 ± 92.98,18.56 ± 2.26).However,the indicators of group C (5.16 ± 2.52,355.60 ± 72.62,7.81 ± 1.76 ) were significantly decreased compared with those of groups A and B (all P ＜0.05 ).MVD and Glut-1 expression of group B increased slightly compared with those of group A ( 19.50 ± 1.96,0.20 ± 0.09 vs 17.90 ± 2.02,0.15 ± 0.04),but the difference was not statistically significant.Nevertheless,the two indicators were significantly decreased in group C ( 8.40 +1.84 and 0.07 ±0.06,P ＜0.05).VEGF expression in group B (0.42 ±0.13) was significantly higher than that in groups A and C (0.17 ±0.04 and 0.16 ± 0.09) ( both P ＜ 0.05 ).The changes of T/M were positively correlated with the changes of tumor cell density between groups A and B ( r =O.81,P ＜ 0.05 ).Changes of T/M were positively correlated with the changes of tumor cell density,Ki67 LI,MVD and Glut-1 between groups A and C (r =O.83,0.71,0.68,0.62,all P ＜ 0.05 ).ConclusionsThe changes of 18 F-FDG uptake in C6 glioma rats were only correlated to the changes of tumor cell density at 48 h after radiotherapy.However,the changes of 18F-FDG uptake closely correlate to the changes of a variety of biological indicators at 1 week post radiotherapy.

OBJECTIVETo observe clinical curative effect of cake-separated moxibustion on impaired glucose regulation (IGR) and explore its action mechanism.

METHODSSixty cases were randomly divided into a simple lifestyle intervention group (control group) and a cake-separated moxibustion combined with lifestyle intervention group (observation group), 30 cases in each one. The control group was treated with lifestyle intervention. Based on lifestyle intervention, cake-separated moxibustion at Pishu (BL 20), Weishu (BL 21) and Yishu (EX-B 3) was applied to the observation group. Fast plasma glucose (FPG), two hours plasma glucose after oral glucose tolerance test (OGTT2hPG), fasting insulin (FINS), homa insulin resistance index (HOMA-IR), blood lipid, body mass index (BMI) and waist circumference (WC) were observed in the two groups before and after treatment.

RESULTSAfter treatment, the OGTT2hPG and FPG were both decreased significantly (both P<0.05) in the two groups, compared between the two groups, the differences of FPG [(0.41 +/- 0.42) mmol/L vs (0.05 +/- 0.08)mmol/L] and OGTT2hPG [(0.85 +/- 0.53)mmol/L vs (0.17 +/- 0.19)mmol/L] were both statistically significant. There were no significant changes in FINS, HOMA-IR, blood lipid, BMI and WC in the control group before and after treatment (all P>0.05), but FINS, HOMA-IR levels, triglycerides (TG), total cholest-erol (TC), low density lipoprotein (LDL-C), BMI and WC in the observation group were decreased obviously after treatment (all P<0.05), which had statistical differences between the two groups (all P<0.05).

CONCLUSIONThe cake-separated moxibustion combined with lifestyle intervention can obviously control blood glucose levels, improve insulin resistance and blood lipid levels, decrease BMI and WC.

OBJECTIVETo study the rehabilitation effects ergometry on COPD patients.

METHODSThirty COPD out-patients in our Hospital were randomly divided into 2 groups. Rehabilitation group, 15 patients, performed leg ergometry exercise of 80% peak Watt x 30min/d x 3d/w x 12w. Another 15 patients were control group without exercise. All patients received conventional therapy. Pulmonary function testing (PFT), cardiopulmonary exercise testing (CPET), arterial blood gas analysis (ABG), Borg and CAT sores were done at both baseline and 12 w.

RESULTSThere was no statistically difference in lung function testing, blood gas analysis and cardiopulmonary exercise test when pre- exercises between 2 sub-groups. The IC, peak VO2 and peak, W of rehabilitation group significantly increased (P < 0.05); and Borg and CAT.scores significantly decreased (P < 0.05) from baseline; and other PFT and ABG did not change (P > 0.05). While there was no difference in control group (P > 0.05).

CONCLUSIONLeg submaximal ergometry rehabilitation improves health condition and ameliorate dyspnea symptoms in COPD patients.

OBJECTIVETo evaluate the effects of different fluid resuscitation strategies on superoxide dismutase (SOD), malondialdehyde (MDA) and myeloperoxidase (MPO) activities in the lung tissue in pregnant rabbits with uncontrolled hemorrhagic shock.

METHODSThirty pregnant New Zealand rabbits were randomized into 5 equal groups, namely the sham shock.(SS) group, shock group without interventions (SH group), and hemorrhagic shock groups with conventional normal saline (NS) resuscitation, NS hypotensive resuscitation, and hypertonic hyperosmotic hypotensive resuscitation (NS, NH, HHH groups, respectively) 30 min after the shock. At the end of the experiment, the rabbits were sacrificed, and the lungs were taken for detection of MDA, MPO and SOD levels.

RESULTSIschemia-reperfusion injury of the lungs in uncontrolled hemorrhagic shock resulted in decreased SOD and increased MDA and MPO contents. The MDA and MPO contents in HHH group were significantly lower than those in NH group, and both the groups, MDA and MPO contents were significantly lower than those of NS group (P<0.05). SOD activity was significantly higher in HHH group than in NH group (P<0.05).

CONCLUSIONIn pregnant rabbits with uncontrolled hemorrhagic shock, hypotensive resuscitation more effectively ameliorates ischemia-reperfusion injuries in the lungs than aggressive fluid resuscitation, and hyperosmotic crystalloid and hyperonoctic colloid resuscitation provide significant protective effects against such injuries.

OBJECTIVETo compare the effect of transurethral resection of the prostate combined with endocrine therapy (TURP + ET) with that of αlA-blockers combined with ET ((αlA-b + ET) in the treatment of bladder outlet obstruction (BOO) in patients with advanced prostate cancer (PCa), and to investigate the safety of the TURP + ET for the treatment of PCa with BOO.

METHODSWe retrospectively analyzed 63 cases of PCa with BOO, 28 treated by αlA-b + ET and the other 35 by TURP + ET. We obtained the residual urine volume (RV), maximum urinary flow rate (Qmax), International Prostate Symptom Score (IPSS), and quality of life score (QoL) before and after treatment along with the overall survival rate of the patients, followed by comparison of the parameters between the two methods.

RESULTSAt 3 months after treatment, RV, IPSS, and QoL in the TURP + ET group were significantly decreased from (137.8 ± 27.6) ml, (22.3 ± 3.6), and (4.2 ± 0.8) to (29 ± 13.6) ml, (7.8 ± 2.1), and (1.6 ± 0.5) respectively (P < 0.05), while Qmax increased from (5.6 ± 2.1) ml/s to (17.6 ± 2.7) ml/s (P < 0.05); the former three parameters in the αlA-b + ET group decreased from (133.6 ± 24.9) ml, (21.5 ± 3.2), and (4.7 ± 1.1) to (42 ± 18.3) ml, (12.8 ± 2.6), and (2.5 ± 0.7) respectively (P < 0.05), while the latter one increased from (6.3 ± 2.4) ml/s to (11.7 ± 2.3) ml/s (P < 0.05), all with statistically significant differences between the two groups (P < 0.05). The overall survival rate of the TURP + ET group was not significantly different from that of the αlA-b + ET group (51.4% vs 46.4% , P > 0.05).

CONCLUSIONTURP + ET is preferable to αlA-b + ET for its advantage of relieving BOO symptoms in advanced PCa without affecting the overall survival rate of the patients.

OBJECTIVETo investigate the efficacy of the application of transosseous osteosynthesis with annular external fixator for the treatment of traumatic large bone defects of the tibia.

METHODSFrom 2002 to 2011,17 cases of traumatic tibial long bone defect were treated by transosseous osteosynthesis with annular external fixator including 11 males and 6 females with an average age of (31.00+/-2.35) years old ranging from 22 to 45 years. The length of defect was from 5 to 13.1 cm with an average of (7.50+/-1.01) cm. The fixed time,bone healing time and the extend length of the affected limb were observed, and the degree of recovery of limb function after surgery were assessed ccording to the Paley's limb function evaluation.

RESULTSAll patients were followed up from 12 to 48 months with an average of (30.00+/-2.35) months, the bone defects of 17 patients achieved bone healing. The average bone healing time was (10.10+/-0.59) months (8 to 15 months); the average time of fixed time was (14.10+/-0.65) months (12 to 16 months); the average extend length of the affected limb was (7.50+/-1.01) cm. The results of Paley's functional evaluation was excellent in 9 cases,good in 6,fair in 2.

CONCLUSIONTransosseous osteosynthesis with annular external fixator is an effective method for treatment of large bone defects of the tibia. It is successful reconstruction of limb length, simple operation, less soft tissue injury,and is clinical worthy of promotion.

Objective To investigate the effect of non invasive cardiac output monitoring(NICO)system in pig model with acute respiratory distress syndrome(ARDS),and to provide experimental basis for clinical application. Methods Eleven anaesthetized and ventilated ARDS male pig models were induced by intravenously infusing 0.2 mL/kg oleic acid. Lung recruitment was condocted by pressure control ventilation on pigs with ARDS. The optimal positive end-expiratory pressure(PEEP)was determined by optimal dead space fraction〔the ratio of dead space to tidal volume(VD/VT)〕. Cardiac output(CO)was determined by NICO,the respiratory function was monitored, and the VD/VT,dynamic compliance(Cdyn),oxygenation index(PaO2/FiO2),the volume of alveolar ventilation(Valv) and arterial blood oxygen saturation(SaO2)were recorded before infusing oleic acid,after stabilization of ARDS model and at optimal PEEP level,and the intrapulmonary shunt fraction(Qs/Qt)was calculated. CO was also determined by application of pulse indicated continuous cardiac output(PiCCO),and the linear regression analysis between CO determined by NICO and CO determined by PiCCO was conducted. Results Seven experimental ARDS pigs model were successfully established. The optimal PEEP identified by the lowest VD/VT method was(15.71±1.80)cmH2O (1 cmH2O=0.098 kPa). Compared with before infusing oleic acid,VD/VT and Qs/Qt after stabilization of ARDS model were significantly increased〔VD/VT:(72.29±8.58)% vs.(56.00±11.06)%,Qs/Qt:(21.04±15.05)%vs.(2.00±1.32)%,both P<0.05〕,and SaO2 and Valv were significantly decreased〔SaO2:0.888±0.108 vs. 0.999±0.053,Valv(mL):92.06±35.22 vs. 146.11±45.43,both P<0.05〕. VD/VT,Qs/Qt,SaO2 and Cdyn at optimal PEEP level were improved to the levels before infusing oleic acid〔(61.07±9.30)%,(3.21±6.10)%, 0.989±0.025,(117.14±41.14)mL〕. Cdyn and PaO2/FiO2 after stabilization of ARDS model were significantly lowered compared with those before infusing oleic acid〔Cdyn (mL/cmH2O):14.43±5.50 vs. 38.14±6.72, PaO2/FiO2 (mmHg, 1 mmHg=0.133 kPa):78.71±23.22 vs. 564.37±158.85, both P<0.05〕. Cdyn and PaO2/FiO2 at optimal PEEP level〔(19.71±4.86)%,(375.49±141.30)mmHg〕were elevated compared with the levels after stabilization of ARDS model(both P<0.05),but still lower than those before infusing oleic acid(both P<0.05). Compared with the levels after stabilization of ARDS model,CO at optimal PEEP level showed obvious decrease from(4.18±2.46)L/min to(3.95±2.69)L/min without significant difference(P>0.05). There was linear correlation between CO determined by NICO and CO determined by PiCCO(r2=0.925,P<0.001). Conclusions NICO technique provides a useful and accurate non invasive estimation of CO and respiratory function.VD/VT provided by NICO can titrate the optimal PEEP in patients with ARDS.
