In this paper, menstruation prescriptions were selected from "Fu Qingzhu's Obstetrics and Gynecology" and analyzed by using GRI algorithm, correlation analysis, hierarchical clustering method through SPSS, Clementine and traditional Chinese medicine (TCM) inheritance auxiliary systems, in order to screen out 15 menopathy prescriptions, which involve 45 traditional Chinese medicine herbs. In the study, blood-tonifying and qi-tonifying herbs were found to be frequent in the prescriptions. The most frequent single herb was white paeony root, accounting for 9.6% in the total number of prescriptions; The most frequent herb pairs were white paeony root-radix rehmanniae preparata and paeony root-angelica sinensis. Among Fu Shan's menopathy prescriptions, 61 herbal pairs showed a correlation coefficient exceeding 0.05, which evolved into 16 pairs of core combinations. The analysis showed that menopathy prescriptions in volume 1 of "Fu Qingzhu's Obstetrics and Gynecology" focused on tonic traditional Chinese medicines involving liver, spleen and kidney and were adjusted according to changes in qi, blood, cold, hot and wet, which could provide a specific reference for further studies on Fu Shan's academic thoughts and traditional Chinese medicine clinical treatment of menopathy.

Objective To investigate the value of drug intervention for difficult weaning from mechanical ventilation. Methods A prospective single-blind randomized controlled trial was conducted. 120 patients with difficult weaning from mechanical ventilation encountered in Department of Critical Care Medicine of Peking University Third Hospital from January 2008 to December 2013 were included,and the patients were divided into treatment group and control group according to random number table,with 60 cases in each group. Patients received furosemide therapy in the treatment group 3 days before weaning up to 48 hours after weaning in order to control negative liquid balance. Enema was given the day before weaning to reduce abdominal pressure. On the weaning day,all of the patients received nitroglycerin and beta blocker or cedilanid to prevent or control elevation of blood pressure and heart rate in the process of weaning. All patients in treatment group received anisodamine in small dosage 2 hours before extubation.The patients in control group received conventional treatment without drug intervention. Baseline indexes of two groups were compared,including the heart rate,respiration rate(RR),mean arterial pressure(MAP),pulse blood oxygen saturation(SpO2),blood gas,hemoglobin(HG),albumin(ALB)and creatinine(Cr). The main reasons of difficulty in weaning,sedative and analgesic drug selection,presence of abdominal discomfort before weaning,interval between sputum suction before extubation,liquid balance at the beginning of the investigation and at time of weaning,24 hours and 48 hours after weaning,failures of spontaneous breathing test(SBT),length of mechanical ventilation,length of ICU stay,and total length of mechanical ventilation and total length of ICU stay during hospitalization. Results There was no statistically significant difference in the heart rate,RR,MAP,SpO2,blood gas,HG,ALB,Cr at the beginning of the investigation between the two groups. The main reasons for difficult weaning in both groups of patients were respiratory dysfunction,cardiac insufficiency,and central nervous system dysfunction. The use of propofol combined dexmedetomidine in the treatment group was more frequent than the control group〔16.7%(10/60)vs. 1.7%(1/60),χ2=8.107,P=0.004〕,and there was no statistically significant difference in the use of other combinations of sedative drugs between the two groups. Abdominal discomfort before weaning was milder in treatment group as compared with control group〔10.0%(6/60)vs. 25.0%(15/60),χ2=4.675,P=0.031〕. The interval between sputum suction before extubation in the treatment group was significantly longer than that of the control group〔hours:1(1,2)vs. 1(1,1),Z=-2.209,P= 0.027〕. SBT failure was less frequent in treatment group compared with control group〔times:0(0,1)vs. 1(1,2),Z=-6.561,P=0.000〕. Liquid balance was better in the treatment group than the control group at time of weaning,24 hours and 48 hours after weaning〔at time of weaning:-567.71 (-755.95,-226.41)vs. 1 256.76(472.48,1 796.63),Z=-9.038,P=0.000;24 hours after weaning:-5.03 (-530.28,245.09)vs. 342.28(125.36,613.25),Z=-4.711,P=0.000;48 hours after weaning:115.50(-450.26, 485.00)vs. 330.00(16.25,575.25),Z=-1.932,P=0.053〕. Compared with control group,length of mechanical ventilation〔days:1.0(1.0,2.0)vs. 2.0(2.0,3.0),Z=-6.545,P=0.000〕,ICU stay time〔days:3.0(3.0,4.0) vs. 4.0(4.0,5.0),Z=-6.545,P=0.000〕,and total length of mechanical ventilation〔days:8.0(6.0,12.0)vs. 11.0(8.0,15.0),Z=-4.091,P=0.000〕and total length of ICU stay during hospitalization〔days:12.5(9.2,19.0) vs. 17.0(12.0,29.5),Z=-2.722,P=0.000〕were all significantly shorter in the treatment group. Conclusions Adjuvant drugs therapy is helpful in patients weaning from the mechanical ventilation,and can shorten length of mechanical ventilation and ICU stay time. Propofol,combined dexmedetomidine,is helpful for weaning.

Recent years, chemical constituents from spice volatile oils have gained worldwide concern owing to its multiple pharmacological effects and safety for using as the natural antibacterial agents. However, their poor dissolution, strong volatility, serious irritation, weak stability, easy oxidation and low bioavailability characteristics are the major obstacle in the preparation of effective oral formulation and practical application. Therefore, there is an urgent need to select a novel carrier system that can delivery the chemical constituents from spice volatile oils more efficiently with improving their stability as well as alleviating the irritation, and develop the functional food, health products and even medicine for exerting their pharmacological effects, which also is the focus and nodus of the research on their application. This review presents recent systematic studies on their novel carrier systems, including cyclodextrin inclusion complex, liposomes, nanoemulsions, nanoparticles, solid dispersion and so on, and summarizes the characteristics, application range and problems of each novel carrier systems, in order to provide some beneficial thoughts in further developing new products of chemical constituents from spice volatile oils.

Objective To observe the effects of 1,25-dihydroxyvitamin D3 on the expressions of transforming growth factor-β1(TGF-β1), fibronectin(FN),and vascular endothelial growth factor(VEGF) in rats with diabetic nephropathy(DN), and to elucidate the protective mechanism played by 1,25-dihydroxyvitamin D3. Methods DN models were estabolished by injecting streptozotoein ( STZ ) into male SD rats, which were divided into TGF-β1 overexpression group, TGF-β1 overexpression plus vitamin D3 group, TGF-β1 low-expression group, TGF-β1 low-expression plus vitamin D3 group, TGF-β1 normal-expression group, and TGF-β1 normal-expression plus vitamin D3 group. After 1,25-dihydroxyvitamin D3 treatment for 37 days, renal function and blood biochemical parameters were evaluated. The morphology and fibrosis of kidney tissues were observed. The expressions of TGF-β1, FN, and VEGF in kidney cortex were measured by immunohistochemistry, realtime PCR, and Western blotting. Results The levels of cholesterol, triglyceride, creatinine,plasma glucose, HbA1C , and 24 h urinary protein were lower in vitamin D3treated groups than those in corresponding control groups(P<0. 05). The degree of renal fibrosis was raised with the increased level of TGF-β1. Vitamin D3 treatment decreased the fibrosis in diabetic kidney. There were significant differences in the mRNA and protein expressions of TGF-β1 in three control groups(P<0. 05). With the increased levels of TGF-β1, the expressions of FN and VEGF were increased. The expressions of TGF-β1, FN, and VEGF were lowered by vitamin D3compared with the corresponding control groups(P<0. 05). Conclusion 1,25-dihydroxy-vitamin D3 may protect the renal tissure in diabetic rats via inhibiting the expressions of TGF-β1, FN, and VEGF in the kidney.

Objective To investigate the effects of ischemic postconditioning (Post) on myocardial cell apoptosis and expres- sion of Bcl-2 and Bax protein during ischemia/reperfusion period in rabbits.Methods Eighteen rabbits were randomly allocated to three groups (6 in each group),sham operation (group S),ischemia/reperfusion group(group IR) and ischemic postconditioning group(group Post).Group IR and group Post were subjected to 15 minutes of left anterior descending coronary artery occlusion followed for 30 minutes of reperfusion.Ischemic postconditioning was achieved by three 30 seconds cycles of reperfusion,each followed by 30 seconds ischemia.Cardiomyocyte apoptosis were determined by in situ TDT-mediated dUTP nick end labeling (TUNEL) and DNA electrophoresis.The expression of Bcl-2 and Bax proteins in apoptotic myocardial cells were detected by immunohistochemistry sepa- rately.Results Compared with group IR,apoptotic index was significantly reduced in group Post [(28.06?2.92) % vs.(55.70? 13.96)%,P

OBJECTIVETo reveal the transmembrane signal pathway participating in regulating neuron functions of treating Alzheimer's disease (AD) by acupuncture.

METHODSSAMP8 mice was used for AD animal model. The effect of acupuncture method for qi benefiting, blood regulating, health supporting, and root strengthening on the amount and varieties of transmembrane signal proteins from hippocampal lipid rafts in SAMP8 mice was detected using HPLC MS/MS proteomics method.

RESULTSCompared with the control group, acupuncture increased 39 transmembrane signal proteins from hippocampal lipid rafts in SAMP8 mice, of them, 14 belonged to ionophorous protein, 8 to G protein, 8 to transmembrane signal receptor, and 9 to kinase protein. Totally 3 main cell signal pathways were involved, including G-protein-coupled receptors signal, enzyme linked receptor signal, and ion-channel mediated signal. Compared with the sham-acupuncture group, acupuncture resulted in significant increase of kinase signal protein amount. From the aspect of functions, they were dominant in regulating synapse functions relevant to cytoskeleton and secreting neurotransmitters.

CONCLUSIONThe cell biological mechanism for treating AD by acupuncture might be achieved by improving synapse functions and promoting the secretion of neurotransmitters through transmembrane signal transduction, thus improving cognitive function of AD patients.

OBJECTIVETo investigate the expression of long non-coding RNA-HOTAIR in prostate cancer cells and its effects on the growth and metastasis of the cells.

METHODSUsing quantitative reverse-transcription PCR (qRT-PCR), we determined the relative expression of HOTAIR in the normal human prostate epithelial cell line RWPE-I and prostate cancer cell lines PC-3 and DU145. We detected the effects of HOTAIR on the cell cycle and invasiveness of prostate cancer cells by RNA interference, flow cytometry, and Transwell mitration assay.

RESULTSThe expressions of HOTAIR in the PC3 and DU145 cells were increased 3.2 and 5.7 times, respectively, as compared with that in the normal RWPE-1 cells. After si-HOTAIR interference, the prostate cancer cells were arrested in the G2 phase and downregulated in the G1 phase. The invasive ability of the prostate cancer cells was evidently inhibited, with the inhibition rates of 32% and 44% of the PC3 cells and 43% and 34% of the DU145 cells for si-HOTAIR1 and si-HOTAIR2, respectively.

CONCLUSIONIncRNA HOTAIR is highly expressed in prostate cancer, which is associated with the growth and invasiveness of prostate cancer cells. HOTAIR is potentially a novel marker for the diagnosis and prognosis of prostate cancer.
