PRESENT SITUATION OF STUDY AND VIEW ON FUNCTIONAL DYSPEPSIA TREATED WITH SPECIFIC ACUPOINTS IN ACUPUNCTURE

Acupuncture plays a dominant role in treating functional dyspepsia （FD）. By reviewing and e- valuating clinical ROT and fundamental research with high quality in the past 17 years, it is found that specific acupoints are the chief in the treatment of FD; additionally, there are differences between specific acupoints and non-specific acupoints in therapeutic effect, explaining that the specificity of meridian points plays an im- portant role in treatment. However, because of inadequate high-quality researches in clinics, the specificity of acupoints can＇t be proved until the researches of clinical effect and mechanism of therapeutic difference are intensified.

OBSERVATION ON THE THERAPEUTIC EFFECT OF BIRD-PECKING MOXIBUSTION OF SPECIFIC ACUPOINTS IN THE TREATMENT OF FUNCTIONAL DYSPEPSIA

Objective: To observe the therapeutic effect of moxibustion of some specific acupoints for treatment of functional dyspepsia (FD, qi-distension type). Methods:A total of 50 cases of FD patients were randomly divided into treatment group (n=26) and medication group (n=24). In treatment group, bird-pecking moxibustion was applied to Zhongwan (CV 12), Qihai (CV 6), Neiguan (PC 6) and Gongsun (SP 4) 5～6 times in every treatment till the local skin got flush. The treatment was given once daily, continuously for 10 days. In control group, the patients were ordered to take Motilium 10 mg/time, 3 times daily. Following 10 days’ treatment the therapeutic effect was assessed.Results:After treatment, of the 26 cases in treatment group, 11 (42.3%) were cured, 7 (26.92%) had remarkable improvement in their symptoms, 6 (23.07%) had improvement and 2 (7.69%) failed, with a total effective rate of 92.31%. Of the 24 cases in medication group, 9 (37.50%) were cured, 6 (25.00%) experienced remarkable improvement in their symptoms, 6 (25.00%) were improved and 3 (12.50%) failed, with a total effective rate of 87.50%. Comparison between two groups showed that the therapeutic effect of moxibustion was significantly superior to that of medication (P<0.05). In addition, the difference value of the therapeutic effect index (TEI) between post-and pre-treatment in treatment group was also significantly higher than that of medication group (P<0.05). Conclusion: Bird-pecking moxibustion of specific acupoints can effectively improve clinical symptoms of FD patients.

EFFECTS OF LOW-FREQUENCY ELECTROACUPUNCTURE ON THE IMMUNOLOGIC FUNCTION IN MORPHINE DEPENDENCE RATS

Objective: To observe the effect of low-frequency electroacupuncture (EA) on the immunologic function in morphine dependence rats. Methods: Forty SD rats were used in this study. Morphine-dependence model was established by intraperitoneal injection of morphine hydrochloride continuously for 5 days and hastened by administration (i.p) of Naloxone. These rats were randomly divided into control, model, EA and auto-demorphinization groups with 10 cases being in each group. In EA group, "Guanyuan"(CV 4),"Mingmen"(GV 4), etc. were punctured and stimulated electrically. Positive T lymphocyte subgroups, CD + 4 and CD + 8 in the peripheral blood were detected with fluorescence immuno-assay. Results: In model group, serum percentage of CD + 4 and CD + 4/CD + 8 decreased considerably in comparison with those of control group (P<0.01); while in EA group, CD + 4 level and CD + 4/CD + 8 increased significantly compared with those of model group (P<0.01); and no significant differences were found between auto-demorphinization group and model group and between EA and control groups in these two indexes. Conclusion: Low-frequency EA can promote the restoration of the immune function of morphine dependence rats.

Genotype Analysis of Yuzhenxiang, a Long Grain, High Quality Aromatic Rice Cultivar

In China,the market share of a rice cultivar is mainly determined by its yield and quality.Yuzhenxiang is a high-quality variety with extra-slender grain shape,good quality and unique aroma.In order to investigate its genetic background,12 pairs of functional markers were used to detect the genotype distribution of eight major grain shape genes including GS3,GW5,GS6,GW6a,GL7/GW7,GLW7,GW8,GS9,one amylase gene Wx and one aroma gene BADH2 in Yuzhenxiang by using Nipponbare,9311,Huazhan,Zhonghui 8015 and Zhonghui 9308 as controls.The results indicated that the slender grain type of Yuzhenxiang was probably affected by GS3 and GL7/GW7 with the positive co-regulation of multiple grain shape genes,and its outstanding rice quality may be resulted from the cumulative effects of GLW7,GW8 and Wx genotypes,while its unique aroma may be mainly regulated by BADH2-E7 deletion.

Analysis of the Porosity Changing after Moisture Absorption in Functional Knitted Fabrics

The paper analyses the effect of stitch geometrical modality changing after moisture absorption on the porosity of knitted fabrics,and educes the formulas between porosity and stitch parameters.Regarding as the cell stitch,the increasing of yarn diameter brings the porosity decreasing and the fabric shrinking in the wale direction.While the diameter keeps invariability,the yarn elongating brings the fabric humping up as well as the increasing porosity.The air-permeability experiments have been conducted to validate the theoretical analysis,and there is reasonable agreement between the theories and experiments.

Research on resting spontaneous brain activity and functional connectivity of acupuncture at uterine acupoints

Objective The resting-state functional magnetic resonance imaging(rs-f MRI)method was used to observe brain activity and its functional connection upon electroacupuncture stimulation at bilateral uterine acupoints(EX-CA1),as well as to investigate the mechanism of acupuncture in the treatment of gynecological diseases.Methods Twenty-two healthy female subjects were stimulated by electroacupuncture at bilateral uterine acupoints;rs-f MRI data of the brain were acquired and standardized.Degree centrality(DC),amplitude of low-frequency fluctuation(ALFF),and regional homogeneity(ReHo)were used to analyze local spontaneous brain activity via acupuncture.An independent component analysis was used to evaluate the functional connectivity of the resting brain networks after acupuncture.Results Analytical results showed that the neural activity intensity of the precuneus lobe,orbitofrontal cortex,lingual gyrus,amygdala,and posterior central gyrus decreased after acupuncture(voxel P<0.001,cluster P<0.05).Functional connectivity analysis revealed weakened auditory and right frontal-parietal networks(voxel P<0.001,cluster P<0.05),enhanced visual network(voxel P<0.001,cluster P<0.05),and synergistic auditory network and hypothalamic-pituitary system.Conclusion Significant differences in neural activity and functional connectivity in specific brain regions were observed after acupuncture intervention at uterine acupoints;the hypothalamic-pituitary system also showed various active states in different brain regions.It is speculated that the effective mechanism of acupuncture at uterine acupoints is related to the regulation of reproductive hormones,emotional changes,and somatic sensations.Therefore,the methods used in this study could clarify the neural mechanism of uterine-point acupuncture in the treatment of gynecological diseases and may serve as a reference for other studies pertaining to acupuncture.

CLINICAL RESEARCH ON THE EFFECT OF ACUPUNCTURE ON THE LEFT VENTRICULAR CONTRACTION FUNCTION IN SYMPTOMLESS CARDIAC FAILURE PATIENTS

Objective: To observe the effect of acupuncture therapy on the function of myocardial contraction in symptomless cardiac failure patients.Methods: A total of 60 cases of symptomless cardiac insufficiency inpatients were randomly divided into medication and acupuncture groups, with 30 cases in each group. For patients of acupuncture group, Neiguan (PC 6), Ximen (PC 4), Tanzhong (CV 17), Xinshu (BL 15), Jueyinshu (BL 14) and Geshu (BL 17) were punctured, twice daily, with 30 days being a therapeutic course. In medication group, patients were asked to take Capoten 25 mg (t.i.d.). The left ventricular ejection fraction (LVEF) and its fractional shortening (FS) of the minor axis were used as the indexes for assessing the therapeutic effect and detected by using a color ultrasonic Doppler apparatus. Results: After one course of treatment, of the each 30 cases of acupuncture and medication groups, 13 (43.3%) and 16 (53.3%) had marked improvement, 16 (53.3%) and 14 (46.7%) had improvement, and 1 (3.3%) and 0 had no any effect respectively. No significant difference was found between two groups in the therapeutic effect. It shows acupuncture therapy can improve myocardial contraction function. Conclusion: Acupuncture has a similar effect in enhancing the systolic function of the myocardium.

Holistic Acupuncture approach to idiopathic refractory nausea,abdominal pain and bloating

AIM： To evaluate the effectiveness of a holistic acupuncture approach on nausea, pain, bloating and electrogastrogram （EGG） parameters in patients with intractable symptoms.METHODS： Twelve patients with no or mild nausea （those without nausea had bloating or pain） and 10 with a histool of moderate to severe nausea were referred for acupuncture. All underwent an EGG and were treated at acupuncture points PC6, SP4 and DU20. Visual analog scales （VAS） assessing severity of nausea, pain and bloating were obtained before and after acupuncture treatment. Nineteen patients received three and three patients received two treatments.RESULTS： VAS scores for nausea reflected the clinical assessment and differed significantly between mild and moderate/severe nausea groups. Acupuncture significantly improved severity of nausea in both groups with improved pre-treatment nausea between the first and third treatments in the moderate/severe nausea group. Pain scores improved with acupuncture in the mild nausea group only and bloating improved only with the first treatment in this group. Patients with bloating with VAS scores greater than 35 pre-treatment improved with acupuncture and over all VAS scores for pain improved with treatment. Acupuncture increased the power in the 2.7 to 3.5 cpm range in the EGG.CONCLUSION： In this uncontrolled clinical study, a holistic acupuncture approach significantly improved nausea in patients with refractory symptoms and increased the power in the 2,7-3,5 cpm component of the electrogastrogram, Bloating and pain VAS scores improved acutely with treatment, This study suggests that acupuncture may be effective in this refractory group of patients and further study using appropriate controls is warranted,

TWENTY-THREE CASES OF ATROPHIC RHINITIS TREATED BY DEEP PUNCTURE AT THREE POINTS IN THE NASAL REGION

Atrophic rhinitis is a disease which manifests itself mainly by anosmia due to dryness and atrophy of the nasal mucosa. There is no specific therapy for the disease at present. In the past few years, 23 cases of atrophic rhinitis were treated mainly by deep puncture at three points in the nasal region with satisfactory results. In order to find out the functional changes of the nasal mucosa, the mucociliary transport rate (MTR), surface temperature of the conchal mucosa, acid-base scale of nasal secretion, and volume of nasal secretion were determined before and after the treatment.

Mediated protective effect of electroacupuncture pretreatment by miR-214 on myocardial ischemia/reperfusion injury

Background Electroacupuncture pretreatment plays a protective role in myocardial ischemia/reperfusion （I/R） injury and microRNAs （miRNAs） could act on various facets of cardiac function. However, the role of miRNAs in the cardioprotection by electroacupuncture pre-treatment on myocardial I/R injury remains unknown. The purpose of the study was to examine whether miR-214 was involved in cardio-protection by electroacupuncture. Methods Using rat myocardial I/R model, we examined the role of electroacupuncture pretreatment in myocardial I/R injury and analyzed the changes in the expression of miR-214. In addition, I/R was simulated in vitro by performing oxy-gen-glucose deprivation （OGD） on H9c2 cell cultures, and the effect of electroacupuncture pretreatment on I/R injury as well as expressional level of miR-214 were examined in vitro. Furthermore, the miR-214 mimic was transfected into OGD-treated H9c2 cells, we analyzed the cell apoptosis, lactate dehydrogenase （LDH） and creatine kinase （CK） activities, intracellular free Ca2＋concentration （[Ca2＋]i） as well as the relative protein levels of sodium/calcium exchanger 1（NCX1）, BCL2-like 11 （BIM）, calmodulin-dependent protein kinase IIδ（CaMKIIδ） and Cyclophilin D （CypD）. Results The in vivo results revealed that compared with the I/R group, the electroacupuncture pretreatment group showed significant decreased myocardial infarct size, as well as the increased indices of the cardiac function, including heart rate, mean arterial pressure, left ventricular systolic pressure and maximal rate for left ventricular pressure rising and declining （±dp/dt max）. In addition, electroacupuncture pretreatment could inhibit the elevation of LDH and CK activities induced by I/R injury. The quantitative PCR （qPCR） results demonstrated electroacupuncture pretreatment could provide cardioprotection against myocardial I/R injury in rats with miR-214 up-regulation. In the meanwhile, in vitro, electroacupuncture pretreatment protected H9c2 cells from OGD-induced injury. Trans-fection of miR-214 mimic showed protective effects on OGD-induced injury to H9c2 cells by reducing apoptosis, decreasing LDH and CK activities, rescuing the OGD-induced Ca2＋and down-regulating elevated protein levels of NCX1, BIM, CaMKIIδand CypD. Conclusions Our findings firstly demonstrated that electroacupuncture pretreatment promotes the expression of miR-214 in myocardial I/R injury and miR-214 contributes to the protective effect of electroacupuncture on myocardial I/R injury.

Avian magnetic compass:Its functional properties and physical basis

The avian magnetic compass was analyzed in bird species of three different orders - Passeriforms, Columbiforms and Galliforms - and in three different behavioral contexts, namely migratory orientation, homing and directional conditioning. The respective findings indicate similar functional properties： it is an inclination compass that works only within a functional window around the ambient magnetic field intensity; it tends to be lateralized in favor of the fight eye, and it is wavelength-dependent, requiring light from the short-wavelength range of the spectrum. The underlying physical mechanisms have been identified as radical pair processes, spin-chemical reactions in specialized photopigments. The iron-based receptors in the upper beak do not seem to be involved. The existence of the same type of magnetic compass in only very distantly related bird species suggests that it may have been present already in the common ancestors of all modem birds, where it evolved as an all-purpose compass mechanism for orientation within the home range [Current Zoology 56 （3）： 265-276, 2010].
