d the motor function of limbs, reduce the width of the third ventricle and improve the clinical therapeutic effect of regaining consciousness in the patients with PVS.OBJECTIVE To display the low hydraulic resistance channel along the running course of the Conception Vessel (CV) by using in vivo fluorography, so as to provide evidence for the existence of meridians of traditional Chinese medicine from the aspect of interstitial fluid channel. METHODS A total of 24 male SD rats were randomly divided into 3 groups, namely CV-low impedance spots (CV-LIS), CV-low hydraulic resistance points (CV-LHRP) and non-meridian points (NMP) groups (n＝8 in each group). The CV-LIS (the imaged line between the xiphoid process and symphysis pubis), CV-LHRP (lateral and parallel to LIS) and NMP (lateral and parallel to CV-LHRP) were detected by using meridian detector and biofluid resistance meter, respectively. Sodium fluorescein solution (1%) was injected into the spot (A-spot, upper 1/5 of the CV-LIS), and one of the NMP (about 1 cm lateral and parallel to the A-spot, and the mid-point between the Kidney and Stomach meridian running courses) by using a microsyringe for observing the migration trace of sodium fluorescein. RESULTS After injection of fluorescein, the migration trace of fluorescein appeared along the CV-LIS and CV-LHRP lines, and only local diffusion was found in the NMP group. The migration trace lengths along the CV-LIS and CV-LHRP were significantly longer than that of the NMP group (P less then 0.01), and the migration width of CV-LIS and CV-LHRP groups was significantly smaller than that of the NMP group (P less then 0.01). The migration speed of CV-LIS and CV-LHRP groups was significantly higher than that of the NMP group (P less then 0.01). CONCLUSION Fluorography is able to be used to display the running course of CV, possibly supporting the existence of meridians from the interstitial fluid channel and providing a new method for visualization of meridians.OBJECTIVE To observe the effect of fire-needle stimulation of "Neixiyan"(EX-LE4) and "Dubi"(ST35) on changes of motor function, structure of cartilage degradation and inflammatory factors in knee osteoarthritis (KOA) rats, so as to explore its underlying mechanisms in improving KOA. METHODS Thirty-nine male SD rats were randomly divided into normal, model and fire-needle groups (n＝13 in each group). The KOA model was established by injection of Monoiodoacetate (MIA, 1 mg) into the lumen of the right knee joint. On the 7th day after successful modeling, fire-needle was applied to EX-LE4 and ST35, twice a week for 3 weeks. The rats' behavioral reactions of gait (0 to 3 points) and claw pressure (0 to 3 points) were scored, and histopathological changes scored by assessing the impairment grade (0 to 6) and stage (0 to 4) of the articular cartilage after safranin O-fast green staining. The contents of serum Interleukin (IL)-1α， Tumor necrosis factor α(TNF-α), IL-10, IL-37 and transforming growth factor β(TGF-β) wh was milder in the fire-needle group. CONCLUSION Fire-needle can improve motor function and relieve impairment of articular cartilage of KOA rats, which may be related to its effects in reducing inflammatory factors and in increasing anti-inflammatory factor levels.OBJECTIVE To observe the effect of moxibustion at "Zusanli"(ST36) on peripheral and central IL-6, IL-10 and IL-10/IL-6 changes in fatigue rats, so as to explore its mechanisms underlying relief of fatigue. METHODS Twenty-one male SD rats were randomly divided into normal control, model and moxibustion groups with 7 rats in each group. The fatigue model was induced by exhausted weight-loaded swimming, once daily for 21 days. Moxibustion was applied to bilateral ST36 once every other day, for successive 11 times. The overall state and the body weight were observed. The levels of IL-6 and IL-10 in the serum, gastrocnemius and frontal cortex tissues were detected by enzyme-linked immunosorbent assay (ELISA). RESULTS Compared with the normal group, the body weight was significantly reduced on the 7th, 14th, and 21st day in the model group (P less then 0.05), and considerably increased on the 14th and 21st day in the moxibustion group relevant to the model group (P less then 0.05). After modeling, the levels of IL- and anti-inflammatory cytokine IL-10.OBJECTIVE To observe the effect of acupuncture (Acupunct) on cerebral infarction volume and expression of poly ADP ribose polymerase 1 (PARP1), apoptosis-inducing factor (AIF) and endonuclease G (Endo-G) in the cerebral cortex tissue at different time-points after cerebral ischemia (CI) in acute cerebral infarction rats, so as to explore its underlying mechanisms in prolonging time window of thrombolysis. METHODS Forty-eight SD rats were randomly divided into sham operation, model, intravenous thrombolysis (IVT)-4.5 h, IVT-6 h, IVT-9 h, Acupunct＋IVT-4.5 h, Acupunct ＋IVT-6 h, Acupunct＋IVT-9 h groups (n＝6 in each group). The CI model was established by using modified autologous thromboembolism via the right common carotid artery. Two hours after modeling, rats of the Acupunct groups received Acupunct stimulation of "Shuigou" (GV26) and bilateral "Neiguan" (PC6) for 30 min. Thrombolysis was conducted by injection of recombinant human tissue-type plasminogen activator (rt-PA, 10 mg/kg) via caudal vein. The neurolUSION Acupuncture may improve neurological function, reduce cerebral infarction volume and prolong the time window of thrombolysis in CI rats, which may be associated with its effect in suppressing AIF/PARP1/ Endo-G signaling.OBJECTIVE To explore the mechanism of electroacupuncture (EA) underlying improvement of cerebral infarction (CI) by investigating its influence on expression of cerebral Wnt7a, lymphoid enhancer factor-1 (LEF1), glycogen synthase kinase 3β(GSK-3β) and Dickkopf-1(DKK1) mRNA and proteins in CI rats. Q-VD-Oph clinical trial METHODS A total of 280 male Wistar rats were randomly divided into blank control (n＝10), sham-operation, model and EA groups，and 90 rats of the last 3 groups were further divided into 1, 3, 6, 9, 12 and 24 h, and 3, 7 and 12 d subgroups with 10 rats in each subgroup. The CI model was established by occlusion of the middle cerebral artery (MCAO). The sham-operation group received the same surgical operation but without thread embolus insertion. EA (2 Hz/15 Hz, 2 mA) was applied to "Shuigou" (GV26) for 20 min, once a day for 1, 3, 7 and 12 d, respectively. The neurological deficit was evaluated by using Neurological Severity Scores (NSS). The expression levels of Wnt7a，LEF1, GSK-3β and DKK1 mRNAs and proteins in the right ischemic brain tissues were detected by Quantative real-time PCR and Western blot, respectively.
