Objective To study the cardiac electrophysiology changes of canine asynchrony ischemic heart failure under left ventricular endocardial pacing.Methods Left bundle branch radiofrequency catheter ablation and left anterior descending coronary artery ligation were used to establish the model of ischemic heart failure in 18 healthy dogs.Eighteen healthy dogs were randomly divided into two groups,9 cases in each group.The experimental group was treated with cardiac resynchronization therapy(CRT) in left ventricular endocardium,and the control group underwent the sham operation.ECG and echocardiography were done at 6 weeks after operation.Results The left ventricular ejection fraction in the experimental group was significantly higher than that in the control group(38.32 ± 6.08 vs.30.62 ±8.96).The asynchronization index in the experimental group was significantly lower than that in the control group(35.99 ±5.25 vs.78.21 ± 7.02),and the difference was statistically significant(P＜0.05).QRS(60.58 ± 7.43 vs.68.33 ± 8.01) and QTc(347.09 ± 17.33 vs.367.81 ± 22.02)in the experimental group were significantly shorter than those in the control group(P＜0.05);moreover Tp-e(37.03±9.07 vs.45.76±7.11) and ARI(162.33±22.06 vs.187.21±23.87) in the experimental group were significantly lower than those in the control group(P＜0.05).Conclusion Left ventricular endocardial pacing can produce preferably electrophysiological effects and achieve the goal of effective cardiac resynchronization therapy.

There have been many reports of clinical and experimental researches of microacupuncture therapy, the relevant systematic works, teaching materials and national standards in recent decades. It shows that microacupuncture system has been formed and its influence has been promoted. While the rapid development of microacupuncture therapy, there are the problems and contradictions on nomenclature, explanation of theoretical basis, optimal indications, and multiple systems and schools, etc. All the above have blocked the clinical application and development. It is considered that we need to unify the nomenclature, condense the theoretical basis, clear the optimal indications, promote the exchange and blend among different schools and sum up the outcomes by systematic review and data mining technique.

Professor JIA Chunsheng believes that "Dongyuan's acupuncture therapy" proposed by GAO Wu could not entirely reflect LI Dongyuan's academic thought of acupuncture and moxibustion. Hence, we collected all of the academic works of LI Dongyuan and extracted the texts relevant with acupuncture-moxibustion therapy, titled as Dongyuan's acupuncture-moxibustion therapy. This process contributed to the deeper study on Dongyuan's acupuncture and moxibustion academic thought. By the influence of Dongyuan's acupuncture-moxibustion academic thought, in association with his clinical experience for dozens of years, Professor JIA Chunsheng proposed that acupuncture and moxibustion should pay attention to the regulation and tonification of spleen and kidney. In clinical practice, Zhongwan (CV 12), bilateral Tianshu (ST 25), Qihai (CV 6) and Guanyuan (CV 4) are commonly selected to consolidate the root, cultivate the primary and treat the spleen and kidney simultaneously. The locations of the above selected points are distributed like a star. This "star-like point selection method" points to the importance of the spleen and kidney (the primary qi). For many diseases, especially the disorders of internal injury, the star-like acupuncture therapy is commonly used and the relevant acupoints are supplemented. The good clinical efficacy has been achieved.

AIM: To explore the characters of fibroblast-like (F-L) cells cultured from granunocyte clony stimunating factor (G-CSF)-mobilized peripheral blood cell (PBC) harvests. METHODS: The adherent cells in the PBC harvests were cultured for 2 week in the mediums of RPMI-1640/L-DMEM/G-CSF or interleukin-3 (IL-3) plus RPMI-1640, the cultured F-L cells were analyzed by flow cytometry (FC). RESULTS: The adherent non-confluent F-L cells obtained from the four groups were similar in their phenotypes: CD33+, CD11c+, CD64+, CD14+, CD45+, HLA-DR+, CD86+, CD34-, CD38-, CD3-, CD19-, CD56-, CD29-, CD44-, CD105-. The F-L cells are similar to monocytes except CD38-and were distinct from dendritic cells (DC) or mesenchymal stem cells (MSC). CONCLUSION: The cultured F-L cells are macrophages rather than DC or MSC. G-CSF, rhIL-3 enhances their numbers.

ObjectiveTo observe the clinical efficacy of acupuncture combined with bloodletting and cupping in the treatment of chronic spontaneous urticaria（CSU） and to explore its potential mechanisms of action. MethodsSeventy CSU patients were randomly divided into loratadine group and acupuncture + bloodletting group， with 35 patients in each group. The loratadine group received oral loratadine tablets， 10 mg once daily in the evening. The acupuncture + bloodletting group received acupuncture at Zhongwan （CV 12）， Guanyuan （CV 4）， Tianshu （ST 25）， Zusanli （ST 36）， Sanyinjiao （SP 6）， Xuehai （SP 10）， Quchi （LI 11）， Hegu （LI 4）， Taichong （LR 3）， Baihui （GV 20）， and Shenting （GV 24）， once daily，along with bloodletting and cupping at Dazhui （GV 14） and Geshu （BL 17）， every other day. Both groups were treated for 4 weeks. The 7-day urticaria activity score（UAS7） was assessed before and after the treatment， and levels of serum immunoglobulin E （IgE）， interleukin-4 （IL-4）， interleukin-5 （IL-5）， eosinophil cationic protein （ECP）， plasma tissue factor （TF）， activated factor Ⅶ （FⅦa）， prothrombin fragment 1+2 （F1+2）， D-dimer （D-D） and complement component 5a （C5a） were detected. ResultsA total of 65 patients were included in the final analysis， 32 in the loratadine group and 33 in the acupuncture + bloodletting group. Before treatment， there was no significant difference in UAS7 score， serum IgE， IL-4， IL-5， ECP levels， or plasma TF， FⅦa， F1+2， D-D， C5a levels between groups （P＞ 0.05）. After treatment， both groups showed significant reductions in UAS7 score， serum IgE， IL-4， IL-5， and plasma TF， FⅦa， F1+2， D-D， and C5a levels compared to those before treatment （P＜0.01）. However， after treatment， there was no significant difference in UAS7 score and serum ECP， IgE， IL-4， IL-5 levels between groups （P＞0.05）. The acupuncture + bloodletting group showed lower plasma TF， FⅦa， F1+2， D-D and C5a levels compared to the loratadine group （P＜0.05 or P＜0.01）. ConclusionAcupuncture combined with bloodletting and cupping can effectively improve the skin symptoms of CSU patients and reduce the levels of inflammatory factors. The potential mechanism of action may involve the regulation of the coagulation-complement-mast cell activation axis， thereby inhibiting mast cell degranulation.

OBJECTIVETo compare the effects of acupuncture, electroacupuncture (EA) and moxibustion on functional constipation in rats.

METHODSSixty male Sprague-Dawley rats were divided into a control group (=8), a model group (=11), a medication group (=8), an acupuncture group (=11), an EA group (=11) and a moxibustion group (=11) by random number table. The rats in the model group, medication group, acupuncture group, EA group and moxibustion group were treated with intragastric administration of loperamide hydrochloride for 6 days continuously to establish the functional constipation models, while equal volume of drinking water was administrated to rats in the control group at the same time. The rats in the acupuncture group, EA group and moxibustion group were respectively treated with acupuncture, EA and moxibustion at "Tianshu" (ST 25) and "Shangjuxu" (ST 37) one hour after intragastric administration; rats in the medication group were treated with intragastric administration of cisapride suspension. All the treatment was given once a day for 6 days. At the last day of intervention, the 24-hour food intake, stool quantity and its water content were measured in each group; the pushing rate of intestine was measured; the structure of colon tissue and acidic mucus in its mucous layer were observed by hematoxylin-eosin dyeing and alcian blue dyeing; the expression of stem cell factor (SCF) and c-kit mRNA was detected by real-time PCR.

RESULTSCompared with the control group, the 24-hour food intake and stool quantity were reduced in the model group (both<0.01), and the water content of stool and pushing rate of intestine were reduced (both<0.01); compared with the model group, the stool quantity and its water content were increased in the medication group, acupuncture group, EA group (<0.05,<0.01), which were not significantly different from those in the moxibustion group (both>0.05). The pushing rate of intestine in each intervention group was increased (all<0.01). The 24-hour food intake and stool quantity in the medication group were not significantly different from those in the acupuncture group, EA group and moxibustion group (all>0.05), and the water content of stool was only reduced in the moxibustion group (<0.01). The pushing rate of intestine in the acupuncture group and moxibustion group was lower than that in the medication group (both<0.01), while that in the EA group was not significantly different from that in the medication group (>0.05). The water content of stool in the moxibustion group was lower than that in the acupuncture group and EA group (both<0.01). The pushing rate of intestine in the acupuncture group and moxibustion group was lower than that in the EA group (both<0.01). The HE staining result indicated the structure of colon tissue was normal, complete and similar in each group; the alcian blue staining indicated the acidic mucosubstance in the model group was lower than that in the control group; compared with the model group, the acidic mucosubstance in the medication group, acupuncture group, EA group and moxibustion group was all increased. Compared with the control group, the expression of SCF and c-kit mRNA was reduced in the model group (both<0.05); compared with the model group, the expression of SCF and c-kit mRNA was increased in the medication group, acupuncture group, EA group and moxibustion group (all<0.05); compared with the moxibustion group, the expression of c-kit mRNA was reduced in the acupuncture group and EA group (both<0.05).

CONCLUSIONSAcupuncture, EA and moxibustion all can play a positive regulative role on functional constipation in rats, in which EA has the best efficacy, followed by acupuncture.

OBJECTIVETo analyze the diseases and effects of the manipulations to promoteby filiform needles, with the help of data mining technique.

METHODSLiterature about different manipulations to promoteby filiform needles in recent 60 years was collected in China National Knowledge Infrastructure(CNKI). Then databases were established to mine the relativities among the diseases, subjects, acupoints selection law,routes and directions of meridianand effects.

RESULTS①Total 489 articles were included. The basic manipulations with the frequency of 630 were on the top. The auxiliary and four methods ofrespectively appeared 70 times. The diseases in the internal medicine were treated with the basic and auxiliary methods of the higher frequencies, 311 and 44 times separately. While the four methods ofwere mostly used in the surgical area, 37 timestotally. ②The diseases treated from high to low by lifting, thrusting and twirling represented retention of urine, sequelae of stroke, pain in waist and lower limbs, of which the effect for retention of urine was better than those of the other two, and the lifting and thrusting method was superior to twirling. ③As for the auxiliary methods, 25 times were found about vibration needling; 18 times, twisting. The highest frequency of 6 times for the vibration needling was on the sequelae of stroke; while 4 times for the twisting, stranguria. ④As to the four methods of,was most frequently applied, and its highest frequency of 18 was onsyndrome.

CONCLUSIONSManipulations to promoteby filiform needles are crucial to achieving the effects of acupuncture. The basic methods are widely used in clinic and have been seen good efficacy. While the auxiliary means assist to promoteto stimulate the body,among which the four methods ofare mainly to smooth the meridians and driveof patients with surgical diseases and take meridian blocking the priority.
