Abstract
OBJECTIVE To observe the effect of electroacupuncture (EA) at "Neiguan" (PC 6) on myocardial fibrosis in spontaneously hypertensive rats (SHR), and explore preliminarily the mediating role of cholinergic anti-inflammatory pathway (CAP) and its downstream nuclear factor κB (NF-κB) signaling pathway. METHODS Six 12-week-old WKY male rats were employed as the normal group. Eighteen 12-week-old SHR were randomly divided into 3 groups, i.e. a model group, an EA group and a blocking group (EA after blocking α7 nicotinic acetylcholine receptor [α7nAchR]), with 6 rats in each one. In the EA group, EA was delivered at "Neiguan"(PC 6) and the site 0.5 cm from its left side, with disperse-dense wave, 2 Hz/15 Hz in frequency and 1 mA in current intensity. One intervention took 30 min and was given once every 2 days, lasting 8 weeks. In the blocking group, prior to each EA, the α7nAchR specific blocker, α-bungartoxin was injected intravenously in the tails of the rats. After EA intervention, the systolic blood pressure (SBP), the diastolic blood pressure (DBP) and the mean arterial pressure (MAP) were measured with non-invasive blood pressure monitor. Using echocardiogram, the left ventricular (LV) anterior wall end-diastolic thickness (LVAWd) , LV posterior wall end-diastolic thickness (LVPWd) and the LV end-diastolic internal diameter (LVIDd) were measured. The level of hydroxyproline (Hyp) in the myocardial tissue was determined by using alkaline hydrolysis, and that of acetylcholine (Ach) was detected by ELISA. With the real-time PCR adopted, the mRNA expression of NF-κB p65, tumor necrosis factor α (TNF-α), interleukin (IL)-1β and IL-6 were determined. RESULTS Compared with the normal group, SBP, DBP, MAP, LVAWd and LVPWd were increased (P<0.01), and LVIDd was decreased (P<0.01) in the rats of the model group. SBP, DBP, MAP and LVAWd were dropped (P<0.01, P<0.05), and LVIDd rose (P<0.01) in the EA group when compared with those in the model group. The differences in the above indexes were not statistically significant between the blocking group and the model group (P>0.05). Compared with the normal group, Hyp level and the mRNA expression of NF-κB p65, TNF-α, IL-1β and IL-6 in the myocardial tissue increased (P<0.01, P<0.05) and Ach level decreased (P<0.01) in the model group. Hyp level, the mRNA expression of NF-κB p65, TNF-α, IL-1β and IL-6 in the myocardial tissue were reduced (P<0.05, P<0.01) and Ach level rose (P<0.01) in the EA group when compared with those in the model group. These indexes were not different statistically between the blocking group and the model group (P>0.05). CONCLUSION CAP may be involved in ameliorating the pathological damage of myocardial fibrosis during EA at "Neiguan"(PC 6). The underlying effect mechanism is associated with up-regulating the neurotransmitter, Ach and down-regulating mRNA expression of NF-κB p65 and pro-inflammatory factors such as TNF-α, IL-1β and IL-6 in myocardial tissue.

Abstract
OBJECTIVE To investigate the effect of electroacupuncture (EA) at Neiguan (PC 6) on myocardial fibrosis in spontaneously hypertensive rats (SHRs), and to explore the contribution of interleukin-1 β (IL-1 β), insulin-like growth factor 1 (IGF-1), and transforming growth factor β 1 (TGF- β 1) to the effects. METHODS Nine 12-weeks-old Wistar Kyoto (WKY) male rats were employed as the normal group. Twenty-seven SHRs were equally randomized into SHR, SHR+EA, and SHR + sham groups. EA was applied at bilateral PC 6 once a day 30 min per day in 8 consecutive weeks. After 8-weeks EA treatment at PC 6, histopathologic changes of collagen type I (Col I), collagen type 1 (Col 1) and the levels of IGF-1, 1L-1 β, TGF- β 1, matrix metalloproteinase (MMP)-2 and MMP-9 were examined in myocardial tissure respectively. RESULTS After 8-weeks EA treatment at PC 6, the enhanced myocardial fibrosis in SHRs were characterized by the increased mean fluorescence intensity of Col I and Col 1 in myocardium tissue (P<0.01). All these abnormal alterations above in SHR + EA group was significantly lower compared with the SHR group (P<0.01). Meanwhile, the increased levels of IL-1 β, IGF-1, TGF-β 1 in serum or myocardial tissue of SHRs, diminished MMP 9 mRNA expression in SHRs were also markedly inhibited after 8 weeks of EA treatment (P<0.05 or P<0.01). Furthermore, the contents of IL-1 β, IGF-1, TGF-β 1 in myocardial tissue were positively correlated with the systolic blood pressure and hydroxyproline respectively (P<0.01). CONCLUSION EA at bilateral PC 6 could ameliorate cardiac fibrosis in SHRs, which might be mediated by regulation of 1L-1 β/IGF-1-TGF- β 1-MMP9 pathway.

Abstract
In the present study, we explored whether sirtuin-3 (SIRT3) regulates the proliferation and migration of esophageal squamous cell carcinoma (ESCC) and investigated the mechanisms underlying the oncogene role of SIRT3. siRNA was used to transfect Eca109 cells and downregulate SIRT3. The proliferation and migration of Eca109 cells were examined by the CCK-8 assay, colony formation assay, Transwell assay, and scratch test. Quantitative real-time PCR and Western blotting were used to detect SIRT3, hexokinase 2, AKT, and p-AKT in Eca109 cells. Functional assays showed that downregulation of SIRT3 could inhibit the proliferation and migration of ESCC cells. Reduced SIRT3 expression downregulated hexokinase 2 expression and inhibited AKT activation in ESCC. These results indicated that SIRT3 promote ESCC development and progression by regulating hexokinase 2 through the AKT signaling pathway. SIRT3 promote ESCC proliferation and migration by regulating HK-2 through the AKT signaling pathway.

Abstract
OBJECTIVE To observe the effect of electroacupuncture (EA) at "Neiguan" (PC 6) on cardiac function of ventriculus sinister in rats with spontaneously hypertensive (SHR), and to explore the mediation effect of endothelin-1 (ET-1)/endothelial nitric oxide synthase (eNOS). METHODS Six 12-week-old male Wistar Kyoto (WKY) rats were taken as the normal group. Eighteen 12-week-old SHR were randomly divided into a model group, an EA group and a sham EA group, 6 rats in each group. The rats in the EA group were treated with EA (disperse-dense wave, 2 Hz/15 Hz in frequency, 1 mA in current intensity) at "Neiguan" (PC 6), 30 min each time, once a day for 8 weeks. The rats in the sham EA group were treated with superficial needling at "Neiguan" (PC 6) with no electrical stimulation applied. After treatment, the left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) were tested by echocardiographic analysis. The left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), heart rate (HR), the maximum rate of increase/decrease of left ventricular pressure (±dp/dtmax) were detected. The serum content of ET-1 was detected by ELISA. Western blot was used to evaluate the expression of ETAR, eNOS in myocardial tissue of left ventricular. RESULTS Compared with the normal group, LVEF, LVFS, +dp/dtmax/LVSP and -dp/dtmax/LVSP were decreased (P<0.01, P<0.05), while LVSP, LVEDP, +dp/dtmax and -dp/dtmax were increased (P<0.01) in the model group. Compared with the model group, LVEF, LVFS, +dp/dtmax/LVSP and -dp/dtmax/LVSP were increased (P<0.01, P<0.05), and LVSP and LVEDP were decreased (P<0.01) in the EA group. Compared with the normal group, the serum content of ET-1 and the expression of ETAR in myocardial tissue were increased (P<0.01), whereas expression of eNOS was decreased (P<0.01) in the model group. Compared with the model group, the serum content of ET-1 and the expression of ETAR in myocardial tissue were decreased (P<0.05), whereas expression of eNOS was increased (P<0.05) in the EA group. CONCLUSION EA intervention may alleviate hypertensive cardiac function damage by up-regulating the expression of eNOS protein in myocardial tissue, down-regulating the serum content of ET-1 and the expression of ETAR protein in myocardial tissue.

Abstract
OBJECTIVE To investigate the mechanism of electroacupuncture (EA) with the involvement of sarcoplasmic reticulum Ca2+-ATPase2a (SERCA2a)/phospholamban (PLB) on the synergistic and attenuated effect of aconitine for heart failure. METHODS Thirty SPF-ranked SD rats were randomly divided into a control group, a model group, an EA group, an aconitine group and an EA plus aconitine group, with 6 rats in each group. The rat model of acute heart failure was established by infusion of high-dose propranolol hydrochloride solution into the right femoral vein. After stabilized for 10 min in the modeled rats, EA was exerted at "Neiguan" (PC 6), with disperse-dense wave, 2 Hz/15 Hz in frequency, 3 mA in intensity, for 30 min in the EA group and the EA plus aconitine group; aconitine solution (10 μg/kg) was injected from the left femoral veins in the rats in the aconitine group and the EA plus aconitine group. Hemodynamic indexes such as the left ventricular systolic pressure (LVSP) and the maximum rate of increase/decrease of left ventricular pressure (±dp/dtmax) were detected and arrhythmia types were observed and scored. SERCA2a protein and PLB protein expressions in left ventricular myocardial tissue of rats were detected by multiplex fluorescence Western blot. RESULTS Compared with the control group, LVSP and ±dp/dtmax all were decreased after modeling and at each time point after intervention in the model group (P<0.01). Compared with the model group, ±dp/dtmax was increased in the aconitine group and the EA group at 1 min after intervention (P<0.01, P<0.05), +dp/dtmax was increased at 10 to 60 min after intervention in the aconitine group and at 20 to 60 min after intervention in the EA group (P<0.01, P<0.05), LVSP was increased at 1 min after intervention in the EA group (P<0.01), while LVSP and ±dp/dtmax were all increased at 1 to 60 min after intervention in the EA plus aconitine group (P<0.01, P<0.05). Compared with the aconitine group, LVSP and +dp/dtmax were increased at 1 min after intervention in the EA group (P<0.01, P<0.05), LVSP and ±dp/dtmax at 1 min after intervention while +dp/dtmax at 20 to 60 min after intervention were all increased in the EA plus aconitine group (P<0.01, P<0.05). Compared with the EA group, +dp/dtmax was higher at 10 to 60 min after intervention in the EA plus aconitine group (P<0.01). Compared with the model group, arrhythmia score was higher in the aconitine group (P<0.01). Compared with the aconitine group, arrhythmia score was lower in the EA group and the EA plus aconitine group (P<0.01). As compared with the control group, the expression of SERCA2a protein in the left ventricular cardiomyocytes was decreased (P<0.01), while the expression of PLB protein was increased in the model group (P<0.01). Compared with the model group, the expression of SERCA2a protein was increased in both the EA group and the EA plus aconitine group (P<0.05, P<0.01), and PLB protein expression was decreased in each intervention group respectively (P<0.01, P<0.05). As compared with the EA group and the aconitine group, the expression of SERCA2a protein was increased and the expression of PLB protein was decreased in the EA plus aconitine group separately (P<0.05, P<0.01). CONCLUSION The intervention with electroacupuncture achieves the synergism/ attenuation effect of aconitine for the improvements in heart failure probably by up-regulating the expression of SERCA2a and down-regulating the expression of PLB in myocardial tissue.

Abstract
OBJECTIVE To observe the influence of electroacupuncture(EA) combined with aconitine on the hemodyna-mics, echocardiogram, and arrhythmias in heart failure rats, so as to explore the facilitation and attenuation effects of EA combined with aconitine. METHODS SD rats were randomly divided into control, model, aconitine and aconitine+EA groups, with 6 rats in each group. Propranolol hydrochloride was used to establish the heart failure model. Rats in the aconitine group were trea-ted with aconitine continuously for 1 h (40 μg/kg). Rats in the aconitine +EA group were given the same treatment as the aconitine group, meanwhile, EA (3 mA, 2 Hz/15 Hz) was applied at "Neiguan"(PC6) for 30 min. Left ventricular catheter and small animal ultrasound imaging system were used to observe the heart hemodynamic indexes such as left ventricular systolic pressure(LVSP), maximal rate for left ventricular pressure rising (+dp/dtmax), and maximal rate for left ventricular pressure declining (-dp/dtmax), ejection fraction (EF) and fractional shortening (FS). The incidence rate of arrhythmia and arrhythmia score was observed by electrocardiogram. RESULTS Following modeling and compared with the control group, LVSP, +dp/dtmax, -dp/dtmax, EF and FS in the aconitine group all decreased(P<0.01) and maintained in the model group. The LVSP of rats in the aconitine group was higher than that of the model group at 15 min after administration of aconitine (P<0.05), and +dp/dtmax was higher at 15, 60 min after administration (P<0.05). Since 15 min after administration, EF and FS in the aconitine group were significantly higher than those of the model group (P<0.01, P<0.05). After EA intervention, compared with the aconitine group, LVSP, +dp/dtmax, -dp/dtmax in the aconitine+EA group were significantly increased (P<0.01, P<0.05) during administration and EF and FS in the aconitine+EA group significantly increased at the beginning of administration of aconitine and 30 and 60 min during administration (P<0.05, P<0.01). The incidence rate of arrhythmia was 100% in the aconitine group, and 50.0% in the rats of aconitine + EA group. The arrhythmia score of aconitine + EA group was significantly lower than that of aconitine group (P<0.05). CONCLUSION Aconitine has a certain inotropic effect, but it is easy to cause arrhythmia. The combination of EA and aconitine can not only improve the contractile function of the heart in rats with heart failure, but also reduce the toxic reaction of aconitine.

Abstract
Paclitaxel-induced peripheral neuropathy (PIPN) is a common and intractable side effect of the conventional chemotherapeutic agent paclitaxel. Acupuncture has been reported as an effective alternative therapy in treatment of PIPN in both basic studies and clinical trials. However, there is a lack of comprehensive surveys to summarize the action of acupuncture in management of PIPN. In this review, we briefly demonstrate the basic pathology of PIPN, which includes the activation of ion channels, mitochondrial dysfunction, disruption of axonal transport and also neuro-inflammatory involvement. Meanwhile, we review both the clinical and basic studies as an emphasis to give a general overview of the therapeutic effect of acupuncture against PIPN. Finally, we summarize the current known mechanisms underlying the action of acupuncture against PIPN mainly at peripheral and spinal levels, which include various neurotransmitters, multiple receptors, different types of enzymes and molecules. In conclusion, acupuncture could be considered as a potential alternative therapy in treatment of PIPN, and further clinical and experimental studies are called for in the future.

Abstract
OBJECTIVE To investigate the effect of acupuncture in different tissue structures on deqi and the electromyography of acupoint area. METHODS Twenty healthy subjects, respectively accepted 4 kinds of needling stimulation, i.e. stimulating skin at Zusanli (ST36), stimulating ST36 with and without skin anesthesia using compound lidocaine cream, and stimulating at Dubi (ST35) without skin anesthesia. Deqi sensation of the acupuncturist and subjects were measured according to MGH Acupuncture Sensation Scale (MASS) during needling, and the myoelectricity around the acupoints was recorded simultaneously. The occurrence rate and intensity of the different deqi sensations, the relationship between the acupuncturist's and subjects' deqi sensations, and the integrated electromyogram (iEMG) were analyzed. RESULTS Sharp pain and tingling were the main sensations during skin needling at ST36. Fullness, dull pain, soreness and acupuncturist's tightness were the main sensations during needling with or without skin anesthesia at ST36. Fullness was the main sensation during needling at ST35, while the intensity was lower than that during needling at ST36. A positive correlation in the intensity was found between subjects' fullness and acupuncturist's tightness during needling with or without skin anesthesia at ST36. The subjects' fullness appeared earlier about 5 seconds than acupuncturist's tightness. The iEMGs during subjects' fullness and acupuncturist's tightness were 2-3 times of that before needling. CONCLUSION Deqi sensations such as subjects' fullness, dull pain, soreness and acupuncturist's tightness are mainly related to the activity of the muscles under the acupoints. Subjects' fullness and acupuncturist's tightness always appear together. Acupuncturist's tightness may be mediated by the muscle stretch reflex induced by needling stimulation.

Abstract
OBJECTIVE This study aimed to explore the application effect of lean management in rabies vaccination. METHODS Lean management in rabies vaccination was implemented from July 2020. A total of 2306 patients vaccinated from January to June 2020 were enrolled as routine management group, and 2718 patients vaccinated from July to November 2020 were enrolled as lean management group. The relationship between potential factors and rabies vaccination with 1:1 propensity score matching (PSM) was analysed. The compliance, waiting time for vaccination, and satisfaction of patients of routine and lean management group were statistically analyzed. The changes in the three indicators before and after the implementation and their application effects were compared. RESULTS Compliance rate in lean management group (98.72%) was significantly higher than that in routine management group (93.87%) (χ 2=32.902, P<0.001). The waiting time for vaccination was also significantly shortened (t = 9.209, P < 0.001), and the satisfaction of patients significantly improved (X 2 = 39.611, P < 0.001). CONCLUSION Implementing lean management in all aspects of rabies vaccination can significantly improve patient compliance and work efficiency of nursing staff and improve the patient medical experience.

Abstract
Chronic hypertension evoked aberrant myocardial remodeling is the main reason for progressive death from heart failure. It is of great clinical significance to find effective prevention and treatment methods to block this pathological process. It has been shown that imbalance of the autonomic nervous system (ANS) induced by chronic hypertension, i.e., hyper-excitation of sympathetic nerve system and suppression of parasympathetic (vagal) nerve system, activates immune cells-mediated inflammatory responses, and exacerbates the pathological remodeling of cardiac tissue. Except the negative inotropic outcomes, excitation of vagal nerves also has an anti-inflammatory effect which is mediated by activating the cholinergic anti-inflammatory pathway (CAIP). Previous studies showed that electroacupuncture (EA) could exert anti-hypertensive and systematic anti-inflammatory effects by increasing vagal activity. In addition, preliminary study from our lab demonstrated that EA was able to alleviate the pathological progress from hypertension to cardiac hypertrophy. However, the potential role of CAIP in restoring hypertension induced aberrant myocardial remodeling is still unknown. Herein, based on the alteration of ANS function in hypertension and EA's impact on vagal activity, we propose novel research ideas that EA could attenuate the pathological process of hypertension induced abnormal myocardial remodeling via activating CAIP.

Abstract
The effect of acupuncture-moxibustion on respiratory system and systemic immune inflammatory response were reviewed to explore the possible role of neuroimmunomodulation in the control of inflammatory response and the effect mechanism of cholinergic anti-inflammatory pathway on coronavirus disease 2019 (COVID-19). Acupuncture-moxibustion could produce the local and systemic anti-inflammatory effect on COVID-19 through the activation of cholinergic anti-inflammatory pathway. Compared with humoral anti-inflammatory pathway, the neuronal anti-inflammatory pathway has earlier initiation, rapider action, and more localization, which play a more important role in the initial stage of inflammatory response. This may be an important basis for acupuncture-moxibustion intervention in the early stage of COVID-19. In addition to cholinergic anti-inflammatory pathway, acupuncture-moxibustion may also play an anti-inflammatory role in activating sympathetic nerve, hypothalamic-pituitary-adrenal axis and other neural anti-inflammatory pathways. How acupuncture-moxibustion play its role in stimulating the vagus nerve and sympathetic nerve in different periods of inflammatory response, and whether the effect is based on the selection of acupoints and the methods of stimulation, will be the research direction of the transformation from basic research to clinical research for acupuncture-moxibustion.

Abstract
Long-term hypertension can lead to both structural and functional impairments of the myocardium. Reversing left ventricular (LV) myocardial fibrosis has been considered as a key goal for curing chronic hypertension and has been a hot field of research in recent years. The aim of the present work is to investigate the effect of electroacupuncture (EA) at PC6 on hypertension-induced myocardial fibrosis in spontaneously hypertensive rats (SHRs). Thirty SHRs were randomized into model, SHR + EA, and SHR + Sham EA groups with WKY rats as a normal control. EA was applied once a day for 8 consecutive weeks. The cardiac fibrosis as well as the underlying mechanisms were investigated. After 8 weeks of EA treatment at PC6, the enhanced myocardial fibrosis in SHRs was characterized by an increased ratio of left ventricular mass index (LVMI), collagen volume fraction (CVF), and elevated content of hydroxyproline (Hyp) as well as the upregulated expression of collagen I and collagen III in myocardium tissue of SHRs. All these abnormal alterations in the SHR + EA group were significantly lower compared to the model group. In addition, EA at PC6 significantly improved the pathological changes of myocardial morphology. Meanwhile, the increased levels of angiotensin II (Ang II) and tumor necrosis factor-α (TNFα) and expression of transforming growth factor β1 (TGF-β1), connective tissue growth factor (CTGF), matrix metalloproteinase (MMP)-2, and MMP-9 in the serum or heart tissue of SHRs were also markedly diminished by EA. These results suggest that EA at bilateral PC6 could ameliorate cardiac fibrosis in SHRs, which might be mediated by the regulation of the Ang II – TGF-β1 pathway.

Abstract
BACKGROUND Central injection of corticotrophin-releasing factor (CRF) mimics the effect of stress on gastrointestinal (GI) responses, including inhibition of GI motility. This study was designed to explore the effects of electroacupuncture (EA) on disordered jejunal motility in a rat model of stress induced by intracisternal (IC) injection of CRF. METHODS A stress model was established by IC injection of CRF in Sprague-Dawley rats. GI motility was evaluated by assessing gastric emptying (GE), gastrointestinal transit (GIT) and jejunal motility in vivo. EA was performed at ST36. The functional roles of CRF receptor subtype 1 and subtype 2 (CRFr1 and CRFr2) were examined by IC administration of the corresponding selective CRF antagonists. Protein expression of CRFr1 and CRFr2 in the hypothalamus and jejunum was detected by Western blotting. RESULTS IC injection of CRF significantly inhibited GE, GIT and jejunal motility. EA treatment remarkably improved the disturbed GI motility. Intriguingly, the disordered jejunal motility induced by central CRF was abolished by IC injection of a selective CRFr2 antagonist, indicating the essential role of central CRFr2 in mediating the stress-induced jejunal motor disorder. EA at ST36 decreased central and peripheral expression of CRFr2, which might be one of the potential mechanisms underlying the beneficial effect of EA on jejunal dysmotility in this rat model of stress. CONCLUSION This study suggested that EA at ST36 could ameliorate disordered jejunal motility induced by stress, and that this might be associated with the down-regulation of CRFr2.

Abstract
Background and Purpose Neuropathic pain is a major side-effect of paclitaxel (PTX) chemotherapy. Although the precise mechanisms responsible for this pain are unclear, the activation of neuroglia and upregulation of the TLR4/NF-κB pathway are known to be involved. In this study, we determined whether electroacupuncture (EA) could limit mechanical hypersensitivity resulting from the chemotherapeutic drug PTX in rats, and investigated the potential mechanisms involved. Methods Rats intraperitoneally received a cumulative dose of 8 mg/kg PTX (2 mg/kg per day) or vehicle control on alternate days (day 0, 2, 4 and 6). EA treatment (10 Hz, 1 mA) was applied at bilateral ST36 acupoints in rats once every other day on days 0–14. For sham EA, needles were inserted at ST36 acupoints without electrical stimulation. Mechanical allodynia was measured by mechanical withdrawal latency (MWL) of paws to a mechanical stimulus every 2 days. Protein expression of TLR4 and NF-κB p65, as well as TMEM119 and GFAP (indicators of microglia and astrocytes, respectively) in spinal cord was quantified by Western blot analysis. Levels of inflammatory cytokines IL-1β and TNF-α in spinal cord and serum were detected by ELISA. Results Mechanical allodynia induced by PTX in both paws (right and left) of rats was significantly attenuated by EA but not sham EA treatment. In addition, EA, but not sham EA, inhibited the activation of both microglia (TMEM119) and astrocytes (GFAP) in lumbar spinal cord. Moreover, Western blot analysis revealed that protein expression of TLR4 and NF-κB in spinal cord was suppressed by EA but not sham EA treatment. PTX significantly increased inflammatory cytokines in spinal cord and serum, which were ameliorated by EA treatment but not by sham EA. Conclusion These results indicate that EA treatment attenuates PTX-induced mechanical allodynia. The putative mechanism corroborating this finding could be related to the suppression of activated microglia and astrocytes in spinal cord, as well as the inhibition of the activated TLR4/NF-κB signaling pathway by EA treatment.

Abstract
OBJECTIVE To collect literatures on the application of neural tracing technique in experimental acupuncture research, and summarize its application status in acupoints, meridians and Zang-fu organs. METHODS We collected papers published from databases of CNKI (1979-2017), Wan-Fang (1990-2017), VIP (1989-2017) and PubMed(1997-2017)by using keywords of "neural tracing technique" "neuroanatomic tracing" "neural tracers" and "acupuncture" "electroacupuncture" "auricular acupuncture" "eye acupuncture" "meridians" "acupuncture points" "acupoint injection", and made a summary about the current state of application of neural tracing technique in the fields of acupoint, meridian and Zang-fu organs (viscera). RESULTS A total of 94 articles were collected, the most commonly used neural tracers were horseradish peroxidase and cholera toxin subunit B. The experimental animals used were rat, rabbit, cat, monkey, etc., and injection site was acupoint. After the injection of neural tracers, the survival time of animals was range from 1 day to 12 weeks, and the labelled tissues included neurons and nerve fibers of the sensory, motor, and autonomic systems. The outcomes of neural labeling mainly revealed the segmental pattern, neuroanatomical connection (neural pathways/circuits) and chemical features (shown by immunohistochemical staining) of neurons and nerve fibers innervating both the acupoints and visceral organs, suggesting their involvement in the effect of acupuncture and moxibustion treatment. CONCLUSION This application of neural tracing technology help us understand the under-lying mechanisms of acupuncture and moxibustion interventions from different perspectives of neural pathways/circuits and related chemical properties, which also lays a greater role for this technology in future experimental acupuncture research.

Abstract
OBJECTIVE To investigate the expression of serotonin (5-HT) in local tissue of different acupoint regions at the hind limbs of rats. METHODS A total of 6 male SD rats were used in the present study. The local tissues of "Neiting"(ST44), "Zusanli"(ST36) and "Futu"(ST32) at the hindlimbs were dissected after transcardiac perfusion with fixative solution containing 4% paraformaldehyde, phosphate buffer, etc., fixed again in 4% paraformaldehyde and cut into sections (at 20 µm thick). Then, the tissue sections were subjective into immunofluorescence stain for displaying 5-HT positive cells and calcitonin gene-related peptide (CGRP) -positive fibers, vessel-like structure (labelled with phalloidin) and cellular nucleus (labelled with DAPI), separately. After that, the tissue samples were observed and recorded using a laser confocal microscope. RESULTS The 5-HT labeled cells presented flat or round form in the local tissues of the 3 acupoint regions. These cells were mainly located in the dermis and subcutaneous tissue, and concentrated around the vessel-like structure and CGRP-positive nerve fibers. The number of cutaneous 5-HT positive cells was most in ST44 (156.6±12.1), and fewer in ST36 (83.5±18.2)and ST32(53.3±5.2)in turn. CONCLUSION 5-HT-positive cell is an important member in local tissue of acupoints (ST44, ST36 and ST32), and varies in number according to their locations, suggesting an involvement of different densities of 5-HT-positive cells in different levels of regulatory effects of acupuncture stimulation of these acupoints.

Abstract
Acupuncture sensation, as one of the essential signs of deqi (arrival of qi), is closely associated with curative effect. With systematically reviewing the literature regarding relationship between acupuncture sensations of deqi and different organizational structures of acupoint area (skin, connective tissue, muscles, nerves and blood vessels), it is believed that acupuncture sensation of deqi is the product of various organizational structures in acupoint area, which is closely related to the nervous system. The deqi sensations sensed by the hands of acupuncturists, which is called sense of needle stagnation, maybe caused by the contraction of muscles in the acupoint area during the process of needle manipulation. By system review, this paper puts forward a new research idea to explore the role of different manipulations of needling in generating the sense of qi-generating needle based on different acupoint structure and brain function response system, which could provide some reference for clarifying the scientific mechanism and clinical application of acupuncture sensations of deqi.

Abstract
It has been shown that ischemia preconditioning (IPC) can attenuate the myocardial injury induced by ischemic and reperfusion. But it was rarely used in clinic due to its inoperability. Previous studies indicate that electroacupuncture (EA) pretreatment can mimic myocardial ischemia preconditioning (MIPC) to produce cardioprotective effect. The activated adenosine A 2 b receptor has been proven to be involved in mediating the cardioprotection of IPC. In the studies on acupuncture analgesia, it was reported that adenosine receptor was activated by acupuncture stimulation, and acupuncture pretreatment can affect the acti-vities of intracellular A 2 b receptor. Based on those mentioned above, it is highly likely that the A 2 b receptor may also participate in the cardioprotection produced by acupuncture pretreatment. In this paper, we comprehensively reviewed relevant studies regarding 1) the cardioprotective effect of IPC and its limitations, 2) the similar cardioprotection produced by both acupuncture pre-treatment and IPC, 3) the mechanism underlying myocardial ischemic injury and intracellular calcium regulation, 4) the acti-vation of adenosine receptors and effects of acupuncture, 5) the relationship between adenosine receptors and intracellular calcium ion, and 6) the effect of acupuncture on adenosine receptors, so as to provide a novel assumption that A 2 b receptor may be a key factor in mediating the cardioprotection of acupuncture pretreatment. Our future research will systematically explore the me-chanism of acupuncture pretreatment in protecting ischemic myocardium from myocardial cell adenosine A 2 b receptor and intracellular calcium signal transduction related factors.

Abstract
OBJECTIVE To try to re-map an acupoint atlas in vector mode in the experimental rat by using a new-generation drawing tool. METHODS A total of 5 SD rats were used in the present study. In reference to the current acupoint locations and anatomical structure of rats as well as those of the human body, an acupoint atlas having a stereoscopic mode was re-mapped by using Adobe photoshop/illustrator CS6 imaging processing and drawing system. RESULTS According to the skeletal structure and body surface landmarks, an acupoint atlas consisting of Shuigou (GV26), Baihui (GV20), Tianmen (i.e. Cuanzhu, BL2), Erjian (MA-H6), Dazhui (GV14), Feishu (BL13), Xinshu (BL15), Geshu (BL17), Jizhong (GV6), Pishu (BL20), Shenshu (BL23), Houhui (SI3), Huantiao (GB30), Houhai, Yanglingquan (GB34), Housanli (ST36), Zhaohai (KI6), Sanyinjiao (SP6), Genduan point, Shenmai (BL62), Taichong (LR3), Zhijian (foot), Yongquan (KI1), Guanyuan (CV4), Xiqian, Weijian, Shenque (CV8), Zhongwan (CV12), Qiansanli (LI10), Waiguan (SJ5), Neiguan (PC6), Quchi (CV6), Zhoujie (EX-UE1), Hegu (LI4), Zhijian (hand), Houxi (SI3), Shenmen (HT7), Taiyuan (LU9), Shaohai (HT3), Chize (LU5), Danzhong (CV17), and Chengjiang (CV24) which have been positioned in plane graph mode by Professor HUA Xing-bang and colleagues in 1991. The newly re-mapped acupoint atlas displayed more clearly in the anatomic locations relevant to the traditional one. CONCLUSION A new acupoint atlas with 3 dimension image mode is accomplished in the rat, being more convenient and applicable for researchers to edit the relevant graph materials in paper writing, and playing a possibly useful guidance for the standardization of acupoint selection in experimental acupuncture researches.

Abstract
OBJECTIVE To observe the effect of combined intervention of electroacupuncture (EA) and astragaloside IV(ASIV) on cardiac hypertrophy and transforming growth factor β 1 (TGF-β 1)/Smad signaling in isoproterenol (ISO) induced cardiac hypertrophy rats, so as to investigate its underlying mechanisms in improving myocardial fibrosis. METHODS A total of 50 SD rats were randomly divided into 5 groups: normal control, model (ISO), Propranolol (PRO),ASIV and EA+ASIV groups (n=10 in each group). The myocardial fibrosis model was established by intraperitoneal injection (i.p.) of ISO (10 mg·kg-1·d-1), once daily for 30 days. Rats of the control group were given normal saline (i.p.), those of the PRO group given with PRO (40 mg·kg-1·d-1, gavage), and those of the ASIV and EA+ASIV groups were treated by gavage of ASIV (40 mg·kg-1·d-1), once daily for 30 days. EA (20 Hz, 6 V) was applied to bilateral "Neiguan" (PC 6) for 10 min, once every day for 30 d. The heart mass index (HMI, whole heart weight/body weight) and left ventricular (LV) mass index (LVMI, weight of the LV/body weight) were calculated to assess the state of cardiac hypertrophy. The enzyme linked immunosorbent assay (ELISA) was used to determine the levels of procollagen I carboxy-terminal propeptide (PICP,a marker of extracellular matrix remodeling) and carboxyterminal telopeptide of type I collagen (ICTP, a metabolite of type I collagen) in serum, and Western blot was used to test protein contents of TGF- β 1, Smad 2 / 3, Smad 4, Smad 7 in the left ventricle tissue of the heart. RESULTS After modeling, the HMI and LVMI, serum PICP and ICTP contents and the expression levels of myocardial TGF-β 1, Smad 2/3 and Smad 4 proteins were significantly increased in the model (ISO) group (P<0.05), suggesting a deposition of collagen and cardiac hypertrophy, and were considerably decreased in PRO, ASIV and EA+ASIV groups after the intervention (P<0.05). The expression level of myocardial Smad 7 protein was significantly lower in the model group than in the normal control group (P<0.05), and significantly up-regulated in PRO, ASIV and EA+ASIV groups (P<0.05). Sirius Red staining of the left ventricular myocardium showed a dense deposition of collagen and a severer myocardial fibrosis in the model group, and a relatively lighter fibrosis in the PRO, ASIV and EA+ASIV groups. The therapeutic effects of EA+ASIV were comparable to those of PRO, and were significantly superior to those of ASIV in down-regulating HMI, serum ICTP, and myocardial Smad 2/3 and Smad 4 expression and up-regulating Smad 7 protein (P<0.05). There were no significant differences among the PRO, ASIV and EA+ASIV groups in LVMI, PICP and TGF-β 1 levels, and between the PRO and EA+ ASIV groups in HMI, ICTP, Smad 2/3, Smad 4 and Smad 7 levels (P> 0.05). CONCLUSIONS EA stimulation of PC 6 combined with ASIV can relieve cardiac hypertrophy and myocardial fibrosis in rats, which may be associated with its effects in regulating myocardial TGF-β 1/Smad signaling pathway.

Abstract
The measurement of heart rate variability (HRV) has the advantages of noninvasiveness and simple operation and is widely used in clinical trials and scientific research for assessing reactions of the autonomic nervous system. More and more studies on acupuncture also take HRV as an important index. In addition to the definition, origin, analytical methods, and significance of time domain and frequency domain parameters of HRV, we reviewed the situations of application of HRV to acupuncture research in recent years, analyzed the influence of acupuncture and sham acupuncture, different acupuncture methods, and different acupoints on HRV, and confirmed the role of HRV in reflecting the effect of acupuncture on the vagal and sympathetic systems. However, various interference factors for HRV measurement and diverse methods for data analysis may lead to great differences in the experimental results of HRV and the interpretation of parameters. Therefore, careful analysis is needed in future studies on acupuncture with HRV as an observation index.

Abstract
Acupuncture therapy has a positive role in the prevention and treatment of some related diseases by regulating autonomic nervous function. But it has been found in experimental researches that the modulatory effects of acupuncture on autonomic nervous system are not always consistent with each other. Because in the animal studies on the mechanism of acupuncture intervention, the anesthetic agent has to be used and definitely affects the activities of the autonomic nervous system while playing its pharmacological effects. Hence, it is very significant to explore the rational application of anesthetic agents and minimize their unfavorable impacts on the research outcomes. In the present paper, we make a retrospective analysis on (1) the effect of acupuncture intervention on activities of the autonomic nerve in animal models of myocardial ischemia, gastrointestinal mobility, and urinary system; (2) the effect of anesthetics as isoflurane, urethane, pentobarbital sodium, ketamine, α-chloralose, propofolum, etc. on activities of the autonomic nerve system. In terms of different anesthetic modes and various depths of anesthesia by using isoflurane inhalation, mixed solution of urethane and chloralose, etc., some approaches for assessing the state of anesthesia in accordance with the pupillary reflex, righting reflex, footboard reflex, swallowing reflex, heart rate, blood pressure, body temperature, respiration frequency, ventilation volume, oxygen saturation, partial pressure of carbon dioxide, neuromuscular blo-ckade, etc. in combination with the indexes directly and indirectly reflecting functions of the sympathetic and vagus nerves are proposed to analyze the impact of different anesthetic states on the therapeutic effect of acupuncture in various models of dysfunction of the autonomic nerve system. Under the circumstances, it is possible to provide a reference for rational use of anesthetic agents and dosages in the acupuncture research of autonomic nerve regulation.

Abstract
Objective: To assess the value of immunoglobulin heavy/light chain (HLC) immunoassay on therapeutic response in patients with multiple myeloma(MM). Methods: A total of 45 newly diagnosed MM patients were retrospectively enrolled in Peking Union Medical College Hospital from 2013 to 2016, whose 115 serum samples were consecutively collected. HLC was tested to evaluate response and compare with other methods for M protein detection. Results: ①There were 30 males and 15 females in total of whom the monoclonal immunoglobulin was IgG in 27 (IgGκ∶IgGλ 12∶15) and IgA (IgAκ∶IgAλ 9∶9) in 18. The arerage age of the studied population was 59 (range 43-80) . ② In 34 patients with serum sample at diagnosis, 32 (94.1%) had abnormal HLC ratio (rHLC) while 2 patients with IgG had normal rHLC. The percentages of abnormal rHLC was 81.8% (18/22) at partial response、50.0%(9/18) at very good complete response and 16.0%(4/25) at complete response. ③In 25 patients reaching CR, there were 13 with IgG and 12 with IgA. 4 patients equally split of IgG and IgA had abnormal rHLC at complete response. ④By monitoring the rHLC of some patients consecutively, we found that the remission of rHLC was to some extent behind the remission of SPE and IEF, or even rFLC. Conclusion: Immunoglobulin HLC detection is one feasible method for minimal residual disease detection.

Abstract
BACKGROUND Garzê and Aba form the second largest Tibetan-inhabited area of China. Blood services have never been reported for this region before. OBJECTIVE To assess the current situation and analyse whether a safe and adequate blood supply has been developed in both Garzê and Aba. METHODS We conducted a longitudinal survey covering the period 2011-2016. The subjects of interest were recruited from non-remunerated voluntary donation, blood testing, clinical transfusion practices and infrastructure of local blood service systems. RESULTS The donation rate and blood collection volume were below the average levels of both the Sichuan Province and mainland China. Component therapy was widely used, but inappropriate usage of whole blood existed. A lack of national specific standards for people on the plateaus led to local blood transfusions being conducted without full clinical assessment. Endemic and frequently occurring disease, such as hydatid disease and gastrointestinal disease, were inevitable risks for blood utilisation and safety. The potential influence of religious belief and traditions, like 'male-leaving marriages', of Tibetans on donor recruitment and blood safety requires further research. CONCLUSIONS A relatively safe and complete blood service system has been developed in this region. However, there is still an urgent need for comprehensive and effective support from the government in terms of policies and finance. As an epidemic area of hydatid disease and sexually transmitted disease, this region needs to emphasise public health measures, such as blood safety and inappropriate usage of blood products.

Abstract
The aims of the present study were to observe the effect of electroacupuncture (EA) at Neiguan (PC6) on ischemic myocardium and the involvement of myocardial β1-adrenergic (β1AR) and M2 cholinergic muscarinic receptors (M2AChR) in
the protective effect. The C57BL6 mice were divided into control, model and PC6 groups randomly. The myocardial ischemia (MI) model of mice was established by forced exhaustive swimming (ES). EA at PC6 was performed to the PC6 group for 7 days. The Electrocardiograph (ECG) was recorded before
ES and immediately after ES on the 1st and 7th day. The ECG J-point deviation value and heart rate (HR) were analyzed to evaluate the effect of EA. The β1AR and M2AChR knockout mice were used to explore whether β1AR and M2AChR
in the cardiac myocytes mediated the cardioprotection effect of EA. The β1AR knockout (β1AR-/-) and M2AChR knockout (M2AChR-/-) mice were divided into MI model and PC6 groups respectively and treated the same way corresponding to the groups
of C57BL6 mice. The results showed that the Electrocardiograph (ECG) J-point deviation value in C57BL6 mice were significantly increased after MI (P=0.015 in the model group, P=0.001 in the PC6 group), which is a symptom of MI, while the heart rate (HR) on the 1st
decreased significantly (P<0.05, or P<0.01). Following EA in the C57BL6 mice, the J-point deviation on the 7th day was significantly decreased (P=0.031, decreased 70.05%), but the HR was still much slower than their baseline (both P<0.01). The
increased J-point deviation value and decreased HR level were also observed in both β1AR-/- and M2AChR-/- mice (P<0.05, or P<0.01). While no significant changes were found in the J point deviation after EA intervention on the 7th day,
and in HR of the both types of mice. These results suggested that EA at PC6 could protect the myocardium against ischemic injury, probably mediated by myocardial β1AR and M2AChR.

Abstract
BACKGROUND In acupuncture practice, the most important step is to confirm the location of a sensitized acupoint which reflects a diagnosis and can be stimulated with a specialized needle to treat the disease. Abnormal symptoms such as hyperalgesia or allodynia at the sensitized acupoints in patients with visceral disorders are considered to be in relation with referred pain and neurogenic inflammation. Yet, limited study has investigated the cutaneous neurochemical changes of the sensitized acuponits. METHODS The resent study developed an animal model of gastric mucosal injury (GMI) by HCl administered into the stomach of the rats. Evans Blue (EB) dye was applied by injection of tail vein after mucosal damage to observe the neurogenic plasma extravasation dots in the skin of the rats. The EB dots extravagated in the skin were compared with locations of acupoints. Immnohistochemistry analysis was used to detect the expression of calcitonin gene-related peptide (CGRP)- or substance P (SP)-labeled nerve fibers, histamine (HA)-, serotonin (5-HT)-, and tryptase-labeled cells in EB dots. Images were recorded and analyzed by Confocal imaging system and Olympus Image Processing Software. RESULTS The results showed that GMI resulted in neurogenic plasma extravasation in the skin of the acupoints over the back and abdomen, which mostly occurred in the T9-11 dermatomere. The EB extravasation dots appeared after GMI and disappeared gradually during the natural self-recovery of the gastric mucosa. More SP and CGRP positive nerve fibers were distributed in EB dots than that in regions beside EB dots and in the control, mostly distributed in the nerve fibers around both the vessels and root of hair follicle. Mast cells also aggregated and degranulated to release algogenic substances of 5-HT and HA around the vessels in areas of the EB dots. CONCLUSIONS Our results indicates that the mechanism of EB extravasation in the skin of the acupoints induced by GMI are closely related to neurogenic inflammation, and that the high expression of local allergic substances and nociceptive neuropeptides in the local skin including SP, CGRP, HA, 5-HT, and mast cell tryptase may be the underlying mechanism of the acupoint sensitization.

Abstract
The imbalance of autonomic nervous function after myocardial ischemia (MI) accelerates the development of ischemic myocardial injury. The beta-adrenergic receptor (β-AR) and muscarinic acetylcholine receptor (M-AChR) are the main receptor types of the cardiomyocyte and the binding sites of the cardiac sympathetic and parasympathetic transmitters. In the present paper, the authors review recent progress of experimental researches on the mechanisms of acupuncture therapy in the prevention and treatment of MI, mainly focusing on the signaling of β1-AR and M2-AChR subtypes. Results showed that acupuncture could attenuate the injury of myocardial ischemia via down-regulating the over expression of β1-AR and up-regulating the expression of M2-AChR protein. Correspondingly, acupuncture intervention could reverse the abnormal expression of the intracellular stimulatory G protein and inhibitory G protein caused by MI, and suppress the activity of cellular adenylate cyclase. In addition, acupuncture could also enhance the activity of nitric oxide synthase and the level of nitric oxide in the ischemic cardiomyocytes, and increase the synthesis of cyclic guanosine monophosphate, ultimately reducing the level of cyclic adenosine 3', 5'monophosphate, and lowering the activity of protein kinase A and the inward flow of Ca2+ in cardiomyocytes. In this way, the ischemic myocardial injury is improved at last. However, some results of acupuncture intervention are not identical and need being confirmed further by more approaches.

Abstract
OBJECTIVE To investigate the effect of di-(2-ethylhexyl) phthalate (DEHP) exposure on the growth and development of placenta, uterine natural killer (uNK) cell number and angiogenesis at the maternal-fetal interface in pregnant mice. METHODS From day 1 of pregnancy, pregnant mice were exposed daily to DEHP by oral gavage at 125, 250, or 500 mg/kg for 13 consecutive days. The uterine and placental tissues were then harvested for HE staining and immunohistochemistry to examine the effect of DEHP exposure on the growth and development of the placenta and angiogenesis and uNK cell number at the maternal-fetal interface. RESULTS Compared with the control group, the mice exposed to 500 mg/kg DEHP, but not those exposed to 125 and 250 mg/kg, showed significantly reduced number of embryo implantation (P<0.05). DEHP exposure significantly increased the rate of abortion. DEHP exposure at 125, 250, and 500 mg/kg significantly and dose-dependently lowered the placental weight compared with that in the control group (0.0637±0.0133, 0.0587±0.0176, 0.0524±0.0183 g vs 0.0786±0.0143 g, respectively; P<0.01), and significantly reduced the total area of the placenta and area of spongiotrophoblasts. DEHP exposure resulted in a significant reduction in the number of fetal vascular branches, and collapse and atresia of blood vessels. The mice exposed to DEHP at 125, 250, and 500 mg/kg had significantly lowered numbers of uNK cells (83.2±10.3, 60.7±12.4, and 50.4±14.5/HP, respectively) as compared with the control group (105.1±14.2/HP) at the maternal-fetal interface (P<0.01). CONCLUSION DEHP exposure significantly affects the growth and development of the placenta in mice possibly by suppressing angiogenesis and reducing uNK cell number at the maternal-fetal interface during pregnancy.

Abstract
The therapeutic effect of vacuum-assisted closure (VAC) has been confirmed in many types of complex wounds, but there are few relevant reports regarding seawater-immersed wounds. The aim of this study was to determine the effect of VAC on seawater-immersed wound healing under different negative pressures and explore the optimal negative pressure value. Four purebred miniature pigs were used as the experimental animal models. Four acute, symmetrical wounds were made on each side of the spine and designated as the experimental group (wounds with 2 h of seawater immersion) and the control group (wounds without seawater immersion). Wounds were divided into a conventional dressing group and 3 further groups with different VAC therapies (negative pressure at either 120, 180, or 240 mmHg). The extent of wound healing, and speed of granulation growth and re-epithelialization were measured. Bacterial flora distribution in the wounds was observed, and fibronectin levels in the exudate of the wounds were tested. Results showed that seawater immersion aggravated wound injury and that VAC therapy with 180 mmHg negative pressure induced the fastest epidermis migration, obvious edema elimination, significant capillary proliferation, and the highest level of fibronectin, and that in wounds, the proportion of Gram-negative bacteria tended to decrease and that of Gram-positive bacteria tended to increase. Our results show that VAC promotes seawater-immersed wound healing and that 180 mmHg negative pressure may be optimal for wound healing.

Abstract
AIM: To investigate the effect and mechanism of acupuncture at heterotopic acupoints on jejunal motility, particularly in pathological conditions.
METHODS: Jejunal motility was assessed using a manometric balloon placed in the jejunum approximately 18-20 cm downstream from the pylorus and filled with approximately 0.1 mL warm water in anesthetized normal rats or rats with diarrhea or constipation. The heterotopic acupoints including LI11 (Quchi), ST37 (Shangjuxu), BL25 (Dachangshu), and the homotopic acupoint ST25 (Tianshu), were stimulated for 60 s by rotating acupuncture needles right and left at a frequency of 2 Hz. To determine the type of afferent fibers mediating the regulation of jejunal motility by manual acupuncture, the ipsilateral sciatic A or C fibers of ST37 were inactivated by local application of the A-fiber selective demyelination agent cobra venom or the C fiber blocker capsaicin. Methoctramine, a selective M2 receptor antagonist, was injected intravenously to identify a specific role of M2 receptors in mediating the effect of acupuncture on jejunal motility.
RESULTS: Acupuncture at heterotopic acupoints, such as LI11 and ST37, increased jejunal motility not only in normal rats, but also in rats with constipation or diarrhea. In normal rats, manual acupuncture at LI11 or ST37 enhanced jejunal pressure from 7.34 ± 0.19 cmH2O to 7.93 ± 0.20 cmH2O, an increase of 9.05% ± 0.82% (P < 0.05), and from 6.95 ± 0.14 cmH2O to 8.97 ± 0.22 cmH2O, a significant increase of 27.44% ± 1.96% (P < 0.01), respectively. In constipated rats, manual acupuncture at LI11 or ST37 increased intrajejunal pressure from 8.17 ± 0.31 cmH2O to 9.86 ± 0.36 cmH2O, an increase of 20.69% ± 2.10% (P < 0.05), and from 8.82 ± 0.28 cmH2O to 10.83 ± 0.28 cmH2O, an increase of 22.81% ± 1.46% (P < 0.05), respectively. In rats with diarrhea, MA at LI11 or ST37 increased intrajejunal pressure from 11.95 ± 0.35 cmH2O to 13.96 ± 0.39 cmH2O, an increase of 16.82% ± 2.35% (P < 0.05), and tended to increase intrajejunal pressure (from 12.42 ± 0.38 cmH2O to 13.05 ± 0.38 cmH2O, an increase of 5.07% ± 1.08%, P > 0.05), respectively. In contrast, acupuncture ST25, a homotopic acupoint, not only decreased intrajejunal pressure, but also significantly decreased frequency in normal rats and rats with constipation or diarrhea. Following demyelination of Aδ fibers, acupuncture at ST37 again augmented intrajejunal pressure to 121.48% ± 3.06% of baseline. Following capsaicin application for 24 h, acupuncture at ipsilateral ST37 increased intrajejunal pressure to 106.63% ± 1.26% of basal levels when compared to measurements prior to capsaicin treatment (P < 0.05). Acupuncture at LI11, ST37, or BL25 significantly rescued methoctramine-mediated inhibition of jejunal motility amplitude from 42.83% ± 1.65% to 53.43% ± 1.95% of baseline (P < 0.05), from 45.15% ± 2.22% to 70.51% ± 2.34% of baseline (P < 0.01), and from 38.03% ± 2.34% to 70.12% ± 2.22% of baseline (P < 0.01), respectively.
CONCLUSION: Acupuncture at heterotopic acupoints increases the amplitude of jejunal motility in rats. C fibers and M2 receptors predominantly and (or) partially mediate the regulation of jejunal motility by acupuncture, respectively.

Abstract
In an 11-year-old boy with osteosarcoma in the proximal tibia (type iii), 2 cycles of dia chemotherapy (cisplatin, ifosfamide, doxorubicin) were administered preoperatively while epiphysiolysis was performed. Clinical response was determined to be complete by radiography and histopathology. Marginal excision was then performed with preservation of the proximal tibial epiphysis. Metaphyseal reconstruction was performed using distraction osteogenesis. Six cycles of dia chemotherapy were administered postoperatively. Twenty months later, the patient had developed no complications and experienced full bone healing, with no limb discrepancy. In selected adolescent patients with osteosarcoma, in whom the tumour is in full contact with the epiphysis, epiphyseal preservation by epiphysiolysis and reconstruction by distraction osteogenesis can provide an excellent outcome, resulting in a stable reconstruction that functionally restores the native limb.

Abstract
Background Our previous studies have demonstrated the treatment benefits of dense cranial electroacupuncture stimulation (DCEAS), a novel brain stimulation therapy in patients with major depression, postpartum depression and obsessive-compulsive disorder. The purpose of the present study was to further evaluate the effectiveness of DCEAS combined with body acupuncture and selective serotonin reuptake inhibitors (SSRIs) in patients with post-stroke depression (PSD). Methods In a single-blind, randomized controlled trial, 43 patients with PSD were randomly assigned to 12 sessions of DCEAS plus SSRI plus body electroacupuncture (n = 23), or sham (non-invasive cranial electroacupuncture, n-CEA) plus SSRI plus body electroacupuncture (n = 20) for 3 sessions per week over 4 weeks. Treatment outcomes were measured using the 17-item Hamilton Depression Rating Scale (HAMD-17), the Clinical Global Impression - Severity scale (CGI-S) and Barthel Index (BI), a measure used to evaluate movement ability associated with daily self-caring activity. Results DCEAS produced a significantly greater reduction of both HAMD-17 and CGI-S as early as week 1 and CGI-S at endpoint compared to n-CEA, but subjects of n-CEA group exhibited a significantly greater improvement on BI at week 4 than DCEAS. Incidence of adverse events was not different in the two groups. Conclusions These results indicate that DCEAS could be effective in reducing stroke patients’ depressive symptoms. Superficial electrical stimulation in n-CEA group may be beneficial in improving movement disability of stroke patients. A combination of DCEAS and body acupuncture can be considered a treatment option for neuropsychiatric sequelae of stroke. Trial registration http://www.clinicaltrials.gov, NCT01174394.

Abstract
OBJECTIVE To observe the cardioprotective effect of electroacupuncture (EA) stimulation at "Neiguan" (PC 6) in mice with myocardial ischemia (MI) and to explore the involvement of cardiac beta-adrenergic receptors (beta-AR) in the cardioprotective effect of EA intervention. METHODS Adult male C 57 BL/6 mice of wild type and beta1/beta2-AR double-knockout (beta1/beta2-AR(-/-)) mice were randomly and respectively divided into control group and EA group, with 8 mice in each group. These mice were subject to procedures of basic control, fatigue swimming and fatigue swimming + EA. The model was established by fatigue swimming for inducing acute MI. EA (2 Hz, 0.5 mA) was applied to bilateral "Neiguan" (PC 6) for 30 min, once daily for 7 days in both EA groups. The ST-segment of electrocardiogram (ECG) of standard limb lead II, heart rate were recorded by using a biophysical amplifier and the arrhythmia score was assessed according to Curtis and Walker's methods (1988). RESULTS Self-comparison showed that, compared with the baseline, the amplitude of ECG-ST II segment was obviously increased in swimming fatigue C 57 BL/6 mice (P < 0.01) and further obviously increased in beta1/beta2-AR(-/-) mice (P < 0.01), suggesting an acute MI in C 57 BL/6 mice and a worsened MI in beta1/beta2-AR(-/-) mice. Simultaneously, the heart rate was markedly decreased (P < 0.05), and the score of arrhythmia obviously increased in both C 57 BL/6 and beta1/beta2-AR(-/-) mice (P < 0.05). Compared with the modeling procedures, ECG-ST II amplitude and arrhythmia score were significantly decreased in C 57 BL/6 mice of the EA group (P < 0.01, P < 0.05), rather than in the beta1/beta2-AR(-/-) mice of the EA group (P > 0.05). In addition, heart rate levels of both C 57 BL/6 mice and beta1/beta2-AR(-/-) mice had no significant differences between control and EA groups (P > 0.05). CONCLUSION EA at "Neiguan" (PC 6) can protect the heart from swimming fatigue-induced MI in C 57 BL/6 mice not in beta1/beta2-AR(-/-) mice, suggesting an involvement of beta1/beta2-AR in the protective effect of EA.

Abstract
Giant cell tumour of bone (gctb) is one type of giant-cell-rich bone lesion characterized by the presence of numerous multinucleated osteoclast-type giant cells. Giant cells are known to express rankl (receptor activator of nuclear factor κB ligand) and are responsible for the aggressive osteolytic nature of the tumour. No available treatment option is definitively effective in curing this disease, especially in surgically unsalvageable cases. In recent years, several studies of denosumab in patients with advanced or unresectable gctb have shown objective changes in tumour composition, reduced bony destruction, and clinical benefit. Denosumab is a fully human monoclonal antibody that targets and binds with high affinity and specificity to rankl. Several large phase iii studies have shown that denosumab is more effective than bisphosphonates in reducing skeletal morbidity arising from a wide range of tumours and that it can delay bone metastasis. The relevant articles are reviewed here. The controversies related to the future use of denosumab in the treatment of gctb are discussed.

OBJECTIVE To compare the effects of carbamyl-beta-methylcholine chloride (CMCC) administered by intra-acupuncture point injection (IAI), intramuscular injection (IMI), and intravenous injection (IVI), and to analyze the mechanisms. METHODS In the IAI group, CMCC was injected into the Zusanli acupoint (ST 36) immediately after 30-min stimulation by electro-acupuncture (EA) at the acupoints, and into the femoral vein and skeletal muscle in IVI and IMI groups, respectively. Intra-gastric pressure was detected. The plasma concentration of CMCC was measured at various times. RESULTS The gastric effect of CMCC in the IVI group was enhanced and attenuated more rapidly than in the other groups. In the IAI group, this effect was significantly stronger than that in the IMI group at 2 min and 15 min, but not significantly different between the two groups at 5 min and 30 min. Plasma concentration of CMCC in the IAI group was similar to that in the IVI group at 2 min, but higher than that in the IMI group. The concentration in the IAI group was higher than that in the IV group and similar to that in the IMI group at 5, 15 and 30 min, indicating rapid increase and slower reduction of the plasma concentration of the drug in the IAI group. There was a positive correlation between the plasma concentration of CMCC and intragastric pressure in all groups. CONCLUSION The effect of IAI with CMCC was stronger than that of IMI and longer-lasting than that of IVI, which correlated with the blood concentration of CMCC.

Abstract
Digitalis glycosides, a group of cardiotonic agents for heart failure, have been used for a long time, but may often trigger arrhythmias as a result of digitalis intoxication. It is of great significance in finding a method to reduce their toxicity and improve clinical curative effects simultaneously in the application of digitalis glycosides. It has been well documented that acupuncture has good therapeutic effects in improving cardiac function and inhibiting arrhythmia induced by myocardial ischemia. Acupuncture combined with chemotherapeutics can reduce the adverse effects of chemotherapeutics. Accordingly, acupuncture combined with digitalis is likely to reduce the side effects of digitalis by regulating intracellular Ca2+, improving the function of Ca(2+)-ATPase in the sarcoplasmic reticulum, increasing calcium sensitivity of cardiac troponin, etc. These considerations may provide a novel clue for treatment of heart failure by joint administration of acupuncture and drugs.

Abstract
OBJECTIVE To observe the influence of electroacupuncture (EA) of different acupoints on changes of mean arterial pressure (MAP), heart rate (HR) and heart rate variability (HRV) in colorectal distension (CRD) rats, so as to analyze the specificity of actions of acupoints in relieving visceral pain and regulating activities of the autonomic nerve system. METHODS Forty-five Wistar rats were randomized into control, Zusanli (ST 36), non-acupoint, Neiguan (PC 6) and Taichong (LR 3) groups (n = 9/group). Under anesthesia, CRD was given to the rats by using an aerostat for 5 min. EA (2 Hz/15 Hz, 2 mA) was applied to bilateral ST 36, non-acupoint (1.0 cm lateral to ST 36), PC 6 and LR 3 for 15 min, respectively. Electrocardiogram of the cervico-chest lead was recorded by using a bioelectric amplifier, and MAP recorded by using a pressure transducer and an amplifier. Low frequency and high frequency of HRV were analyzed by Chart 5.0. RESULTS Following CRD, the HR, MAP, LF and LF/HF levels increased significantly in all the 5 groups (P < 0.05), while HF had no apparent changes (P > 0.05). Compared with the control group, 5 min and 15 min after EA ,and 10 min after ceasing EA, MAP values of ST 36 and PC 6 groups were decreased obviously (P < 0.05). The HR values of ST 36 and PC 6 groups at 15 min after EA and 10 min after ceasing EA were decreased markedly in comparison with those of each of the other groups during CRD (P < 0.05). The LF levels of both ST 36 and PC 6 groups at 5 min after EA, and those of ST 36, PC 6 and LR 3 at 15 min after EA were significantly lower than those of control group (P < 0.05). LF/HF levels of ST 36 and PC 6 at 10 min after ceasing EA were obviously lower than those of control group (P < 0.05). No significant differences were found among ST 36, non-acupoint, PC 6 and LR 3 groups in HR, LF and LF/HF (P > 0.05). CONCLUSION EA of ST 36 and PC 6 can suppress CRD-induced increase of MAP, HR and LF/HF, suggesting beneficial effects of EA in relieving visceral pain and mediating autonomic nerve system. The aforementioned effects of EA of LR 3 and non-acupoint are not obvious.

Abstract
Specificity of acupoints is one of the basic theories of the acupuncture and moxibustion sciences and is a very important basis to guide the clinical treatment of acupuncture and moxibustion. However, the scientific foundation of specificity of acupoints is still unclear, which has greatly restricted to the clinical effect improvement of acupuncture and moxibustion and has influenced to academic status of acupuncture and moxibustion sciences both in China and abroad. In this paper, the recent related researches are reviewed and then the key effects and mechanism that the tissue structure of acupoints can decide and affect specificity of acupoints-organs effects are analyzed and explored. It is held that acupuncture at the different tissue structure of the different depth in the different or the same acupoints will cause changes of varying qualities or degrees of visceral function because of stimulation of the different receptors in the different tissues followed by excitation of varying afferent nerve fibers.

Abstract
AIM To study upon to serum deprivation if delta-opioid receptor activation has direct effect on cultured impaired cardiomyocytes survival. METHODS Myocardial cells of neonatal rats were cultured in vitro. The cell viability was determined with crystal violet staining uptake. The percentage of S + G2 + M in cell cycle was determined by flow cytometry. Apoptosis rates were determined by flow cytometry (FCM). The expression of Caspase-3 were investigated by Western blotting. RESULTS Myocardial cells of neonatal rats were cultured of serum-free in vitro, apoptotic index was significantly increased, the expression of Caspase-3 was significantly increased, free-serum induced apoptosis in cardiac myocytes after 48 h. At concentrations of 10 nmol x L(-1) - 10 micromol x L(-1), a delta opoid receptor agonist [D-Ala2, D-Leu5]-enkephalin DADLE promoted the myocardial cells survival, in a concentration-dependent manner. The optimal response was achieved at 0.1 micromol x L(-1), which increase survival index of cardiac myocyte, percentage of S + G2 + M in cell cycle, decrease apoptotic index of cardiac myocyte, and the expression activate caspase-3. Delta-opioid receptor antagonist naltrindole at 10 micromol x L(-1) inhibited the promoting effects of DADLE, which decrease survival index of cardiac myocyte, and percentage of S + G2 + M in cell cycle, increase apoptotic index of cardiac myocyte and the expression of Caspase-3. CONCLUSION The protective of delta-opioid receptor activation can promote survival in cultured impaired myocardial cells.

Abstract
OBJECTIVE To observe the inhibitory effects of acupuncture pretreatment on arrhythmia and intracellular calcium ([Ca2+]i) oscillation in single cardiocyte in rats subjected to myocardial ischemia-reperfusion (MIR). METHODS Male SD rats were evenly randomized into normal control (NC), MIR and electroacupuncture (EA) groups. MIR was performed by ligation (30 min) and reperfusion (10 min) of the left anterior descending coronary artery in vivo in rats or in the isolated and perfused rat heart subjected to a 40 min global ischemia followed by a 10 min reperfusion. EA pretreatment was applied to bilateral "Neiguan" (PC 6) for 30 min once a day in 3 consecutive days. Arrhythmic score was calculated according to Curtis's and Walker's method, and the count of [Ca2+]i oscillation was measured by using InCytPm 2 intracellular ion detecting system. RESULTS Both the arrhythmic score and the count of [Ca2+]i oscillation in MIR group were considerably higher than those in NC group (P<0.05). While compared with MIR group, the arrhythmia score and the count of [Ca2+]i oscillation in EA group were decreased significantly (P<0.05). CONCLUSION Pretreatment of EA can effectively resist MIR-induced arrhythmia and intracellular calcium oscillation in the rat.

Abstract
Weekly PM2.5 samples were simultaneously collected at a semi-residential (Tsinghua University) and a downtown (Chegongzhuang) site in Beijing from August 2001 through September 2002. The ambient mass concentration and chemical composition of PM2.5 were determined. Analyses including elemental composition, water-soluble ions, and organic and elemental carbon were performed. The annual average concentrations of PM2.5 were 96.5 microg m(-3) and 106.9 microg m(-3) at CGZ and HU site, respectively. More than 80% of the PM2.5 mass concentrations were explained by carbonaceous species, secondary particles, crustal matters and trace elements at the two sites. Carbonaceous species were the most abundant components, constituting about 45% and 48% of the total PM2.5 mass concentrations at CGZ and THU site, respectively. SO4(2-), NO3- and NH4+ were three major ions, accounting for 37%, 23% and 20%, respectively, of the total mass of inorganic water-soluble ions.

Abstract
AIMS To construct a transgenic Bacillus mucilaginosus strain to increase the secretion capability of a wild-type isolate of B. mucilaginosus D4B1 to hydrolyse phytate phosphorus, which can be used as a microbial fertilizer in field application. METHODS AND RESULTS We constructed a phytase secreting expression vector pSP43 with a mini-Tn5 transposon and a Aspergillus fumigatus phytase expression cassette. The vector pSP43 was successfully transferred into the wild-type B. mucilaginosus using the particle bombardment method, and three transgenic strains with a stable copy of phytase expression cassette integrated into the chromosome of the B. mucilaginosus by Tn5 transposition were selected. The phytase activity of the engineered strains increased 36-46-fold when compared with the wild-type strain of D4B1. CONCLUSIONS The A. fumigatus phytase gene can be expressed under the direction of p43 promoter in B. mucilaginosus. The expression protein is secreted extracellularly and newly constructed strains showed a high phytase activity. SIGNIFICANCE AND IMPACT OF THE STUDY A transgenic Bacillus strain by the particle bombardment method was constructed.

Abstract
OBJECTIVE To construct single chain antibody specific to membrane protein of Schistosoma japonicum by genetic engineering technique. METHODS The VH (heavy-chain variable region) and VL(light-chain variable region) genes were amplified by PCR from the genomic DNA of NP11-4 cell line, and sequenced by Sanger's method. The ScFv was constructed in pTHA90 vector using VH and VL genes, then expressed by IPTG. RESULTS The VH and VL genes were obtained through PCR. The DNA sequences showed that VH and VL were new variable region genes of antibody. They were registered by GenBank. A ScFv gene with (Gly4Ser) 3 intralinker in the pTHA90 vector was successfully constructed. The ScFv was expressed as thioredoxin-fused proteins about 36.2 kDa. CONCLUSION A specific ScFv against the membrane protein of Schistosoma japonicum was constructed and expressed.

Abstract
OBJECTIVE To amplify and sequence the light chain of anti-idiotypic monoclonal antibody NP30 of Schistosoma japonicum. METHODS By comparing the conserved regions at each end of the nucleotide sequences of murine germ-line genes encoding FR1 and FR4 regions of immunoglobulin light chain variable regions, we designed a set of primers for amplification of VL gene. The hybridoma cells secreting anti-idiotypic monoclonal antibody NP30 of Schistosoma japonicum were cultured and their genome DNAs were extracted and used as templates for PCR. The PCR product was then cloned into pUC19 vector. The recombinants were sequenced by Sanger's method. The VL gene was compared with GenBank and published mouse VL genes. RESULTS The full-length of VL gene was 318 bp. The VL gene was a member of mouse Ig kappa light chain subgroup IV and generated from rearrangement of germ line V and J kappa 4 genes. The VL gene sequence has been registered by GenBank(accession No. AF206720). CONCLUSION The obtained VL gene was a potentially functional gene of anti-idiotypic monoclonal antibody NP30 of Schistosoma japonicum.
