Objective To compare the clinical efficacy of acupoint catgut-embedding therapy plus fundamental treatment versus fundamental treatment alone for the prevention and treatment of bone marrow depression in breast cancer patients induced by FEC(fluorouracil, epirubicin and cyclophosphamide) chemotherapy. Methods A total of 46 post-operation breast cancer patients accepting the first cycle of FEC chemotherapy were randomly divided into treatment group and control group, 23 cases in each group. The control group was given fundamental treatment including oral use of Chinese medicine of modified Xiangsha Liujunzi Decoction for regulating stomach and arresting vomiting, modified Guipi Decoction and Gui Lu Erxian Decoction for nourishing blood and generating blood, and western medicine of Batilol Tablets and Vitamin B4 Tablets. The treatment group was given acupoint catgut-embedding therapy on bilateral Zusanli(ST36) and Shenshu(BL23) plus fundamental treatment. The effect on bone marrow depression in the two groups was observed after treatment. Results(1) On post-chemotherapy day 7 and 8, the count of white blood cells (WBC) and neutrophils (NE) in the treatment group was higher than that in the control group, the difference being significant(P < 0.05 or P < 0.01).(2) The utilization of granulocyte colony-stimulating factor(G-CSF) in the treatment group was less than that in the control group, the difference being significant (P < 0.05). (3) On post-chemotherapy day 10, the effect on improving bone marrow depression in the treatment group was superior to that in the control group, the difference being significant (P<0.01) . Conclusion The acupoint catgut-embedding therapy plus fundamental treatment is more effective and safe for the prevention and treatment of bone marrow depression in breast cancer patients induced by FEC chemotherapy than fundamental treatment alone.

Objective To investigate the empathic abilities and the association between empathic abilities and executive function in schizophrenic patients. Methods Empathy with the Interpersonal Reactivity Index-C (IRI-C) and executive function with Wisconsin Card Sorting Test (WCST) , Stroop Color-Word Task (Stroop), Spatial n-back Task (n-back) were applied to 74 schizophrenic patients and 69 healthy controls. Results Compared with healthy controls, schizophrenic patients showed significantly lower total scores ((46. 8 ± 10. 0) vs (51.5 ±9.7), P<0.01),and subscores in Perspective Taking ((9.5 ±4.2) vs (12.2 ±3.9) , P<0. 01), Fantasy ((12.5 ±4.2) vs (15.5 ±3.8), P<0.01) and Empathic Concern((15. 9 ±4.2) vs (17. 3 ±3.4), P< 0.05) ,but higher subscore((8.8 ±5. 1) vs (6.5 ±3.7), P<0.01) in personal distress of IRI-C. A significant difference(P<0.01) were fund on the scores of WCST, Stroop task and n-back task between schizophrenic patients and healthy controls. Pearson correlation analysis showed that the total scores of IRI-C was negatively correlated with the response administered (Ra), the number of responses errors (Re) and non-perseverative errors (nRpe) of WCST (r= -0.293, r= -0.253, r= -0.272, P<0.05) respectively, that empathic concern sub-score of IRI-C was negatively correlated with Ra, Re, perseverative responses (Rp) and perseverative errors (Rpe) of WCST (r= -0.326, r= -0.300, r= -0.294, r= -0.287, P<0.01 -0.05) respectively , but positively correlated with Rfp. of WCST (r=0.279, P<0.05), and that the fantasy subscore of IRI-C was negatively correlated with the reaction time of B part(r= -0.299, P<0.01) and C part (r= -0.322, P<0.01) of the Stroop task. Conclusion Schizophrenics have a general impairment of empathy and executive function,and affective empathy is related to the executive function, suggesting that the impairment of executive function maybe the one of pathological mechanism for the empathic deficit of patients with schizophrenia.

Aim To assess the effects of Banqiao Codonopisis Pilosula(BCP)decoction on learning and memory dysfunction in AD model rats induced by high activity GSK-3β and its possible mechanism.Methods The SD rats(4 months old,♂)were divided into five groups,namely,sham-operated group(blank group),AD model group,BCP high-dose(2.16 g·kg-1·d-1)group,BCP medium-dose(1.08 g·kg-1·d-1)group,and BCP lower-dose(0.54 g·kg-1·d-1)group.Treatment group received BCP decoction by gavage once a day for 14 days,while other groups were offered drinking water by gavage once a day for 14 days.The autonomous behavior activities of all rats were observed and recorded after gavage.In the last seven days by gavage,Morris water maze test was used to test the spatial learning and memory ability of the five groups.After five days training,treatment groups and AD model group were injected wortmannin(WT,PI3K specific inhibitor)and GF-109203X(GFX,PKC specific inhibitor)(100 μmol·L-1 of each,total volume of 10 μL)into the right lateral ventricle of the rats.The blank group was only injected 2％DMSO.The spatial memory retention was detected by water maze 24 hours after lateral ventricle injection.Then,changes in the spatial learning memory of rats were observed.The level of Tau phosphorylation in SD rat hippocampus and the expression and activity changes of related protein kinase GSK-3β were detected by Western blot and immunohistochemistry.The changes of Nissl bodies in SD rat hippocampus were observed by Nissl′s staining.Results After intragastric administration of BCP,the rat autonomous behavior activities in each group all showed a declining trend,and the differences in low-dose and middle-dose groups had statistical significance compared with blank group.The Morris water maze tests showed that the latency navigation of model group was significantly longer than that of blank group(P<0.01),while that of the BCP three doses groups was shorter than that of model group(P<0.05).Compared with the same group,the latency navigation of the three groups after gavage BCP low,middle and high dose was significant shorter than that without gavage(P<0.05).Western blot results showed that the activity of GSK-3β in AD model group was up-regulated compared with the blank group.However,BCP inhibited activity of GSK-3β.Western blot and immunohistochemistry results showed the level of Tau phosphorylation in AD model group was increased compared with the blank group in the area of CA3(P<0.05).Compared with AD model group,the level of Tau phosphorylation was decreased in treatment group.Nissl′s staining results showed that dendritic spines in AD model group was significantly attenuated compared with the blank group(P<0.05).Far more dendritic spines were observed in treatment group than in AD model group.The number of Nissl′s bodies in neuron cells of hippocampus in hippocampal CA3 was obviously larger in treatment groups than in AD model group.These effect of BCP was dose-dependent.Conclusions BCP can prevent the learning and memory dysfunction in AD model rats induced by high activity of GSK-3β.The mechanism may be related to inhibiting GSK-3β activity and then reducing the level of phosphorylation of Tau and improving neural development.

OBJECTIVE:To establish PCR reaction system of DNA of Marchantia convoluta in Guangxi marked with SCoT polymorphism marker technique by screening primer and optimizing reaction condition. METHODS:Modified CTAB method was used to extract DNA of M. convolute from Guangxi;gel electrophoresis and UV spectrophotometry were used to investigate purity and concentration of DNA. Using sample DNA as template,PCR amplification of 36 SCoT primers was conducted,and suitable primers were screened after electrophoresis,staining and imaging of products. The orthogonal experiment of 5 factors and 4 levels was conducted by 5 main factors as DNA concentration,Mg2 + concentration,dNTP concentration,primer concentration,Taq DNA polymerase concentration. The condition of SCoT-PCR reaction system was optimized. RESULTS:Extracted sample DNA bands were neat without RNA contamination,degradation or dispersion of fluorescence;sample well was clear. UV absorbance ratio ranged 1.7-2.0 at 260 nm and 280 nm;purity and concentration of DNA were both suitable for follow-up test. PCR results of 36 primers showed that product band of No. 4 primer was neat without diffuse fluorescence but with best luminance,so No. 4 primer was used for PCR reaction. The optimal SCoT-PCR reaction system contained 30.00 μg/mL DNA,2.00 mmol/L Mg2+,0.20 mmol/L dNTP, 0.40 μmol/L primer,0.50 U/mL Taq DNA polymerase(total reaction volume of 20 μL). CONCLUSIONS:Suitable SCoT-PCR primer of DNA is screened,and reaction system is optimized. It provides technologic basis for variety identification and genetic relationship analysis of M. convoluta in Guangxi.

OBJECTIVETo compare the efficacy difference between acupotomy and acupuncture in the treatment of avascular necrosis of femoral head at the early and middle stages.

METHODSThe randomized controlled prospective study method was adopted. Sixty cases of avascular necrosis of femoral head at Ficat-ArletⅠto Ⅱ stages were randomized into an acupotomy group (32 cases) and an acupuncture group (28 cases) by the third part. In the acupotomy group, the acupotomy was adopted for the loose solution at the treatment sites of hip joint, once every two weeks, totally for 3 times. In the acupuncture group,points around the hip joint were selected and stimulated with warm acupuncture therapy, once every day, for 6 weeks. Harris hip score was observed before and after treatment. The efficacy was evaluated in the two groups.

RESULTSHarris hip score was improved significantly after treatment in the two groups (both<0.05). The result in acupotomy group was better than that in the acupuncture group (<0.05). The effective rate was 90.6% (29/32) in the acupotomy group, better than 75.0% (21/28) in the acupuncture group after treatment (<0.05).

CONCLUSIONSHarris hip score and the effective rate in the acupotomy group are better than those in the treatment with routine acupuncture for avascular necrosis of femoral head at the early and middle stages.

ObjectiveTo study the effect of apigenin on the proliferation and apoptosis of human colon cancer CL187 cells and the underlying mechanisms. MethodHuman colorectal cancer CL187 cells were treated with different concentrations of apigenin （0， 30， 45， 60 mg·L^-1） according to the results of the preliminary experiment. The proliferation of CL187 cells was detected by methyl thiazolyl tetrazolium （MTT） and colony formation assays， and the apoptosis was observed via Hoechst 33258 staining. Real-time fluorescence quantitative PCR was conducted to determine the mRNA levels of cysteine protease-3 （Caspase-3）， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax） in the CL187 cells treated with apigenin. Western blot was employed to measure the protein levels of Caspase-3， Bcl-2， and Bax associated with apoptosis， protein kinase B （Akt） and phosphorylated Akt （p-Akt） in phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） pathway， and extracellular signal-regulated kinases 1/2 （ERK1/2）， p-ERK1/2， c-Jun N-terminal kinase （JNK）， p-JNK， p38 mitogen-activated protein kinase （MAPK）， and p-p38 MAPK protein in MAPK pathway. ResultCompared with the blank group， the apigenin groups had low cell survival rates and high inhibition rates on cell proliferation （P<0.01）. Apigenin decreased the cell clone number and clone formation rate， and increased the inhibition rate on clone formation （P<0.01）. After CL187 cells were treated with different concentrations of apigenin for 48 h， typical apoptosis characteristics such as nuclear pyknosis， chromatin condensation， and enhanced fluorescence reaction were observed. Compared with blank group， 45， 60 mg·L^-1 apigenin treatments down-regulated the mRNA level of anti-apoptotic gene Bcl-2 （P<0.01） and all the apigenin treatments up-regulated those of the pro-apoptotic genes Bax and Caspase-3 （P<0.05， P<0.01）. Similarly， apigenin treatments down-regulated the protein level of Bcl-2 （P<0.05， P<0.01） and up-regulated those of Caspase-3 （P<0.05， P<0.01） and Bax （P<0.01， 45， 60 mg·L^-1）. The blank group had higher protein level of Akt than the 60 mg·L^-1 apigenin group （P<0.01）， higher protein levels of p-Akt， ERK1/2， and p-ERK1/2 than the 45， 60 mg·L^-1 apigenin groups （P<0.01）， and higher protein levels of JNK and p-JNK than the apigenin groups （P<0.05， P<0.01）. Compared with blank group， 60 mg·L^-1 apigenin up-regulated the protein level of p38 MAPK （P<0.05）， and all the apigenin groups up-regulated that of p-p38 MAPK （P<0.01）. Furthermore， apigenin lowered the p-Akt/Akt ratio （P<0.05， P<0.01） and p-ERK1/2/ERK1/2 ratio （P<0.01）， while it increased the p-JNK/JNK ratio （45， 60 mg·L^-1； P<0.05， P<0.01） and p-p38 MAPK/p38 MAPK ratio （P<0.05， P<0.01）. ConclusionApigenin can inhibit the proliferation and promote the apoptosis of CL187 cells by inhibiting the PI3K/Akt signaling pathway and regulating the expression of proteins in the MAPK signaling pathway.

ObjectiveTo investigate the effect of Stemona tuberosa alkaloids （STA） on apoptosis and phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） and c-Jun N-terminal kinase/p38 mitogen-activated protein kinase （JNK/p38 MAPK） signaling pathways in human lung cancer A549 cells. MethodA549 cells were classified into blank group and STA groups （100， 150， 200， 250， 300 mg⋅L^-1）. Thiazole blue （MTT） assay and colony formation assay were used to evaluate the proliferation of A549 cells. Apoptosis was observed based on Hoechst 33258 staining， flow cytometry， and Annexin V-FITC/PI staining. Western blot was employed to detect the expression of apoptosis-related proteins cysteine-aspartic acid protease-3 （Caspase-3）， B-cell lymphoma-2 （Bcl-2）-associated X protein （Bax）， and Bcl-2， and the expression of PI3K， phosphorylated （p）-PI3K， Akt， p-Akt， JNK， p-JNK， p38 MAPK， and p-p38 MAPK. ResultCompared with the blank group， STA groups （150， 200， 250， 300 mg⋅L^-1） demonstrated the increase in inhibition rate of cell proliferation （P<0.01） and cell clone inhibition rate， and decrease in cell clone formation rate （P<0.01）. In comparison with the blank group， STA groups showed typical characteristics of apoptosis， such as chromatin condensation and enhanced fluorescence reaction. The apoptosis rate of STA groups was significantly higher than that of the blank group （P<0.01）. Compared with the blank group， STA （150， 200， 250， 300 mg⋅L^-1） significantly up-regulated the protein expression of Caspase-3 and Bax （P<0.05， P<0.01） and down-regulated the expression of Bcl-2 protein （P<0.01）. Compared with the blank group， STA had no significant influence on the total protein expression of PI3K， Akt， JNK， and p38 MAPK. However， STA （150， 200， 250， 300 mg⋅L^-1） significantly decreased the levels of p-PI3K and p-Akt （P<0.05， P<0.01） and increased the level of p-p38 MAPK （P<0.05， P<0.01）. Compared with the blank group， STA （200， 250， 300 mg⋅L^-1） significantly raised the level of p-JNK （P<0.05， P<0.01）. ConclusionSTA can inhibit the proliferation and induce the apoptosis of A549 cells by inhibiting PI3K/Akt signaling pathway and activating JNK/p38 MAPK signaling pathway.

Piperine is a kind of amide alkaloids presenting in Piper nigrum L.，which has the pharmacological action such as protecting cardiovascular system ，regulating glucose and lipid metabolism ，anti-tumor，improving nervous system diseases ， anti-inflammation and so on. This paper summarized the pharmacological action and mechanisms of piperine in recent years and found that piperine ，as the main active ingredient of P. nigrum ，could protect the cardiovascular system by reducing inflammation and oxidative stress ；improve mitochondrial function through anti-inflammatory and antioxidant effects ，thereby regulate glucose and lipid metabolism ；play an anti-tumor role by mediating the signaling pathways of Wnt/β-catenin，NF-κB/Nrf-2/KeAP-1/HO-1， PI3K/Akt，TGF-β1/Smad2/ERK1/2；improve neurological diseases by inhibiting autophagy ，relieving inflammation ，improving antioxidant，inhibiting neuronal apoptosis and regulating the expression of related proteins in neurons ；play an anti-inflammatory effect by inhibiting the activity of NF-κB and other signaling pathways and reducing the expression of inflammation-related proteins. However，the mechanism of action of piperine is not perfect ，and most of the studies have been confined to the pharmacological level or a certain signaling pathway and a certain target ，without being able to elucidate the interconnection between the relevant signaling pathway and the specific target from a holistic perspective. In the follow-up ，the specific targets of piperine can be identified and clinical trials can be carried out to provide support for the clinical application of piperine.
