Acupuncture treatment for depression has definite therapeutic efficacy, and its mechanism has been extensively studied. The extracellular regulatory protein kinase(ERK) signaling pathway is involved in the development and progression of depression. This article reviewed and summarized the research progress on the regulation of the ERK signaling pathway by acupuncture in the treatment of depression in recent years, focusing on the physiological activation and regulatory mechanism of the ERK signaling pathway, its association with the occurrence of depression, and the mechanisms through which acupuncture activates the ERK signaling pathway to treat depression (including enhancing neuronal synaptic plasticity, promoting the release of neurotrophic factors, and inhibiting neuronal apoptosis). Future research could explore the relationship between the ERK pathway and other pathways, investigate other brain regions besides the prefrontal cortex and hippocampus, examine differences in regulatory mechanisms between male and female patients, assess the effects of different acupuncture techniques on the ERK pathway, and increase efforts to explore mechanism of synaptic plasticity regulation, so as to provide reference for the clinical application and mechanism sludy of acupuncture in depression treatment.

Brain mechanism of acupuncture for children with anisometropic amblyopia: a resting functional magnetic resonance imaging study based on voxel-mirrored homotopic connectivity.

AIM: To explore the brain mechanism of acupuncture for children with anisometropic amblyopia using the voxel-mirror homotopic connectivity (VMHC) analysis method of resting functional magnetic resonance imaging (rs-fMRI) technology based on clinical effectiveness. METHODS: Eighty children with anisometropic monocular amblyopia were randomly divided into two groups: control (40 cases, 1 case of shedding) and acupuncture (40 cases, 1 case of shedding) groups. The control group was treated with glasses, red flash, grating, and visual stimulations, with each procedure conducted for 5min per time. Based on routine treatment, the acupuncture group underwent acupuncture of "regulating qi and unblocking meridians to bright eyes", Jingming (BL1), Cuanzhu (BL2), Guangming (GB37), Fengchi (GB20) acupoints were taken on both sides, with the needle kept for 30min each time. Both groups were treated once every other day, three times per week, for a total of 4wk. After the treatment, the overall curative effect of the two groups and the latency and amplitude changes of P100 wave of pattern visual-evoked potential were counted. At the same time, nine children with left eye amblyopia were randomly selected from the two groups and were scanned with rs-fMRI before and after treatment. The differences in the brain regions between the two groups were compared and analyzed with VMHC. RESULTS: Chi-square test showed a notable difference in the total efficiency rate between the acupuncture (94.87%) and control groups (79.49%). Regarding the P100 wave latency and amplitude, the acupuncture group had significantly shorter latency and higher amplitude of P100 wave than the control group. Moreover, the VMHC values of the bilateral temporal lobe, superior temporal gyrus, and middle temporal gyrus were notably increased in the acupuncture group after treatment. CONCLUSION: Acupuncture combined with conventional treatment can significantly improve the corrected visual acuity and optic nerve conduction in children with anisometropic amblyopia. Compared with the conventional treatment, the regulation of acupuncture on the functional activities of the relevant brain areas in the anterior cerebellum may be an effective acupuncture mechanism for anisometropic amblyopia.

Effect of acupuncture at the acupoints for Yizhi Tiaoshen on the functional connectivity between the hippocampus and the brain in the patients with Alzheimer's disease. / 针刺"益智调神"ç©´æ–¹å¯¹é˜¿å°”èŒ¨æµ·é»˜ç— æ‚£è€ æµ·é©¬ä¸Žå ¨è„‘åŠŸèƒ½è¿žæŽ¥çš„å½±å“.

OBJECTIVES: To analyze the effect of acupuncture at the acupoints for Yizhi Tiaoshen (benefiting the intelligence and regulating the spirit) on the functional connectivity between the hippocampus and the whole brain in the patients with Alzheimer's disease (AD), and reveal the brain function mechanism of acupuncture in treatment of AD using resting state functional magnetic resonance imaging (rs-fMRI). METHODS: Sixty patients with mild to moderate AD were randomly divided into an acupuncture + medication group (30 cases, 3 cases dropped out) and a western medication group (30 cases, 2 cases dropped out). In the western medication group, the donepezil hydrochloride tablets were administered orally, 2.5 mg to 5 mg each time, once daily; and adjusted to be 10 mg each time after 4 weeks of medication. Besides the therapy as the western medication group, in the acupuncture + medication group, acupuncture was supplemented at the acupoints for Yizhi Tiaoshen, i.e. Baihui (GV 20), Sishencong (EX-HN 1), and bilateral Shenmen (HT 7), Neiguan (PC 6), Zusanli (ST 36), Sanyinjiao (SP 6) and Xuanzhong (GB 39). The needles were retained for 30 min in one treatment, once daily; and 6 treatments were required weekly. The duration of treatment was 6 weeks in each group. The general cognitive function was assessed by the mini-mental state examination (MMSE) and Alzheimer's disease assessment scale-cognitive part (ADAS-Cog) before and after treatment in the two groups. Using the rs-fMRI, the changes in the functional connectivity (FC) of the left hippocampus and the whole brain before and after treatment were analyzed in the patients of the two groups (11 cases in the acupuncture + medication group and 12 cases in the western medication group). RESULTS: After treatment, compared with those before treatment, MMSE scores increased and ADAS-Cog scores decreased in the two groups (P<0.05); MMSE score was higher, while the ADAS-Cog score was lower in the acupuncture + medication group when compared with those in the western medication group (P≤0.05). After treatment, in the western medication group, FC of the left hippocampus was enhanced with the left fusiform gyrus, the inferior frontal gyrus of the left triangular region, the bilateral superior temporal gyrus and the right superior parietal gyrus (P<0.05), while FC was weakened with the left inferior temporal gyrus, the left middle frontal gyrus and the right dorsolateral superior frontal gyrus when compared with that before treatment (P<0.05). After treatment, in the acupuncture + medication group, FC of the left hippocampus was increased with the right gyrus rectus, the left inferior occipital gyrus, the right superior temporal gyrus and the left middle occipital gyrus (P<0.05), and it was declined with the left thalamus (P<0.05) when compared with those before treatment. After treatment, in the acupuncture + medication group, FC of the left hippocampus was strengthened with the bilateral inferior temporal gyrus, the bilateral middle temporal gyrus, the right gyrus rectus, the bilateral superior occipital gyrus, the left lenticular nucleus putamen, the left calcarine fissure and surrounding cortex, the inferior frontal gyrus of the left insulae operculum, the left medial superior frontal gyrus and the right posterior central gyrus (P<0.05) compared with that of the western medication group. CONCLUSIONS: Acupuncture at the acupoints for Yizhi Tiaoshen improves the cognitive function of AD patients, and its main brain functional mechanism is related to intensifying the functional connectivity of the left hippocampus with the default network (inferior temporal gyrus, middle temporal gyrus and superior frontal gyrus, gyrus rectus), as well as with the sensory (posterior central gyrus) and visual (calcarine fissure and surrounding cortex and superior occipital gyrus) brain regions.

[Effect of different suspension moxibustion methods on syndrome characteristics of rats with rheumatoid arthritis of heat bi syndrome based on "moxibustion can be used for heat syndrome"].

OBJECTIVE: To observe the effects of different suspension moxibustion methods on the syndrome characteristics and inflammatory factors of rats with rheumatoid arthritis (RA) of heat bi syndrome and to prove the concept of "moxibustion can be used for heat syndrome". METHODS: Among seventy Wistar rats, 12 rats were randomly selected as a normal group, and the remaining rats were induced by collagen combined with wind, dampness, and heat environmental stimulation to establish the RA model of heat bi syndrome. Forty-eight rats with successful model establishment were further randomly divided into a model group and three moxibustion groups (mild moxibustion group, rotating moxibustion group and sparrow-pecking moxibustion group), with 12 rats in each group. The acupoints "Quchi" (LI 11), "Dazhui" (GV 14) and ashi point were used in all moxibustion groups, with mild moxibustion, rotating moxibustion, and sparrow-pecking moxibustion intervention given respectively, each acupoint was treated with moxibustion for 10 min a day, and 6 days were considered one course of treatment, with a total of three courses. After the intervention, the arthritis index (AI), the Evans blue (EB) extravasated volume in the soft tissue of the right hind paw, and the levels of tumor necrosis factor (TNF)-α and interleukin (IL)-10 in the serum were measured by ELISA in each group. The volume of the bilateral hind paw was measured; the infrared thermal imaging was collected to analyze the temperature of the plantar area of the bilateral foot pads, and the reaction time of plantar heat pain was calculated before and after modeling, as well as after the 1st, 2nd and 3rd courses of interrention. The ankle dorsiflexion angle of the right hind foot was also measured before and after modeling, as well as after the intervention. RESULTS: After modeling, compared with the normal group, the rats in the model group had more high-temperature areas in the bilateral hind limbs, abnormal AI score, abnormal bilateral hind paw volume, abnormal temperature of the plantar area of the bilateral foot pads, abnormal foot pain response time, abnormal right hind ankle dorsiflexion angle, abnormal right hind paw soft tissue EB extravasation, and abnormal serum TNF-α and IL-10 levels (P<0.01, P<0.05). After the intervention, compared with the model group, the rats in each moxibustion group had decreased or disappeared high-temperature areas in the bilateral hind limbs, EB extravasated volume in the soft tissue of the right hind paw was reduced (P<0.05), and the right ankle dorsiflexion angle was increased (P<0.05), serum level of TNF-α was reduced, and level of IL-10 increased (P<0.05); the AI scores in the mild moxibustion group and the sparrow-pecking moxibustion group was decreased (P<0.01, P<0.05). After the 1st, 2nd and 3rd courses of intervention, compared with the model group, the bilateral hind paw volume of rats in each moxibustion group was decreased (P<0.05, P<0.01), and plantar heat pain reaction time was increased (P<0.05). After the 2nd course and the 3rd course of intervention, the temperature of the right hind paw pad area was decreased in each moribustion group (P<0.05); after the 3rd courses of intervention, the temperature of the left hind paw pad area was decreased in the mild moxibustion group (P<0.05). CONCLUSION: Suspension moxibustion could adjust the serum levels of TNF-α and IL-10 to improve the syndrome characteristics of RA rats of heat bi syndrome, such as joint redness, swelling, heat, pain and activity restriction. The effect of mild moxibustion is the most prominent. The findings could provide scientific basis for "moxibustion can be used for heat syndrome".

[Effects of Yizhi Tiaoshen acupuncture on learning and memory function and the expression of phosphorylated tau protein in the hippocampus of Alzheimer's disease model rats].

OBJECTIVE: To observe the effects of Yizhi Tiaoshen (benefiting mental health and regulating the spirit) acupuncture on learning and memory function, and the expression of phosphorylated tubulin-associated unit (tau) protein in the hippocampus of Alzheimer's disease (AD) model rats, and explore the effect mechanism of this therapy on AD. METHODS: A blank group and a sham-operation group were randomly selected from 60 male SD rats, 10 rats in each one. AD models were established in the rest 40 rats by the intraperitoneal injection of D-galactose and okadaic acid in the CA1 region of the bilateral hippocampus. Thirty successfully-replicated model rats were randomly divided into a model group, a western medication group and an acupuncture group, 10 rats in each one. In the acupuncture group, acupuncture was applied to "Baihui" (GV 20), "Sishencong" (EX-HN 1), "Neiguan" (PC 6), "Shenmen" (HT 7), "Xuanzhong" (GB 39) and "Sanyinjiao" (SP 6); and the needles were retained for 10 min. Acupuncture was given once daily. One course of treatment was composed of 6 days, with the interval of 1 day; the completion of treatment included 4 courses. In the western medication group, donepezil hydrochloride solution (0.45 mg/kg) was administrated intragastrically, once daily; it took 7 days to accomplish one course of treatment and a completion of intervention was composed of 4 courses. Morris water maze (MWM) and novel object recognition test (NORT) were used to assess the learning and memory function of the rats. Using HE staining and Nissl staining, the morphological structure of the hippocampus was observed. With Western blot adopted, the protein expression of the tau, phosphorylated tau protein at Ser198 (p-tau Ser198), protein phosphatase 2A (PP2A) and glycogen synthase kinase-3ß (GSK-3ß) in the hippocampus was detected. RESULTS: There were no statistical differences in all of the indexes between the sham-operation group and the blank group. Compared with the sham-operation group, in the model group, the MWM escape latency was prolonged (P<0.05), the crossing frequency and the quadrant stay time in original platform were shortened (P<0.05), and the NORT discrimination index (DI) was reduced (P<0.05); the hippocampal cell numbers were declined and the cells arranged irregularly, the hippocampal neuronal structure was abnormal and the numbers of Nissl bodies decreased; the protein expression of p-tau Ser198 and GSK-3ßwas increased (P<0.05) and that of PP2A decreased (P<0.05). When compared with the model group, in the western medication group and the acupuncture group, the MWM escape latency was shortened (P<0.05), the crossing frequency and the quadrant stay time in original platform were increased (P<0.05), and DI got higher (P<0.05); the hippocampal cell numbers were elevated and the cells arranged regularly, the damage of hippocampal neuronal structure was attenuated and the numbers of Nissl bodies were increased; the protein expression of p-tau Ser198 and GSK-3ß was reduced (P<0.05) and that of PP2A was increased (P<0.05). There were no statistically significant differences in the above indexes between the acupuncture group and the western medication group (P>0.05). CONCLUSION: Acupuncture therapy of "benefiting mental health and regulating the spirit" could improve the learning and memory function and alleviate neuronal injure of AD model rats. The effect mechanism of this therapy may be related to the down-regulation of GSK-3ß and the up-regulation of PP2A in the hippocampus, and then to inducing the inhibition of tau protein phosphorylation.

[Different operation sequences between acupuncture and cupping therapy for lumbar muscle strain with cold and dampness: a randomized controlled trial].

OBJECTIVE: To compare the clinical efficacy on lumbar muscle strain with cold and dampness between the different operation sequences of acupuncture and cupping therapy. METHODS: Seventy-six patients with lumbar muscle strain with cold and dampness were randomly divided into an acupuncture + cupping group (A + C group, 38 cases) and a cupping + acupuncture group (C + A group, 38 cases, 1 case dropped off). In the A + C group, cupping therapy was delivered 10 min after the end of treatment with acupuncture, while in the C + A group, acupuncture therapy was exerted 10 min after the end of treatment with cupping. Acupuncture was applied to Mingmen (GV 4), Yaoyangguan (GV 3), ashi point and bilateral Shenshu (BL 23), Dachangshu (BL 25), Weizhong (BL 40) and Yanglingquan (GB 34), and the needles were retained for 30 min in each intervention. Flash cupping was operated along the bilateral sides of the lumbar spine for 3 min, and the cups were retained for 10 min at bilateral Shenshu (BL 23), Dachangshu (BL 25) and ashi points. The intervention was delivered once every two days, 3 times weekly, for 3 weeks totally in each group. The scores of visual analogue scale (VAS) and Oswestry disability index (ODI), TCM syndrome score and the mean temperature of the lumbar region before and after treatment were compared between the two groups. The safety and the clinical efficacy were assessed for the interventions of the two groups. RESULTS: Compared with the values before treatment, except for the sleep score of ODI, the VAS scores, ODI scores and TCM syndrome scores were decreased after treatment (P<0.01, P<0.05); while the mean temperature of the lumbar region was increased (P<0.01) in both groups. After treatment, the VAS score and the pain score of ODI in the C + A group were lower than those in the A + C group (P<0.05). The incidence rate of adverse reactions of the C + A group was lower than that of the A + C group (P<0.01). The effective rate in the A+C group was 92.1% (35/38), that in the C+A group was 94.6%(35/37), there was no statistical difference between the two groups (P>0.05). CONCLUSION: Different operation sequences between acupuncture and cupping therapy obtain the similar efficacy on lumbar muscle strain with cold and dampness, but cupping therapy delivered prior to acupuncture has certain advantages in relieving pain and improving safety.

OBJECTIVE: To observe the effect of acupoint thread-embedding on visual acuity and morphology of retina in children with refractive amblyopia. METHODS: A total of 60 children with refractive amblyopia were randomized into an observation group (30 cases, 2 cases dropped off) and a control group (30 cases, 1 case dropped off). In the control group, comprehensive therapy of eye covering of intact side and family refined performance was adopted. On the basis of the treatment in the control group, acupoint thread-embedding was applied at Ganshu (BL 18), Pishu (BL 20), Shenshu (BL 23), Zusanli (ST 36), Guangming (GB 37) in the observation group, once every 2 weeks. The treatment for 2 months was required in the both groups. The corrected vision and the variations of macular thickness of retina and average thickness of retinal nerve fiber layer (RNFL) before and after treatment were observed, and the therapeutic efficacy was evaluated in the both groups. RESULTS: After treatment, the corrected vision was increased compared before treatment in the both groups (P<0.05), and the improvement of corrected vision in the observation group was superior to that in the control group (P<0.05); the macular thickness of retina and the average thickness of RNFL were thinner compared before treatment in the both groups (P<0.05), and the macular thickness of retina and the average thickness of RNFL in the observation group were thinner than those in the control group (P<0.05). The total effective rate was 92.9% (26/28) in the observation group, which was superior to 79.3% (23/29) in the control group (P<0.05). CONCLUSION: Acupoint thread-embedding can effectively increase the corrected vision in children with refractive amblyopia, and has improvement in retina morphological damage to a certain extent.

Actin-Binding Proteins as Potential Biomarkers for Chronic Inflammation-Induced Cancer Diagnosis and Therapy.

Actin-binding proteins (ABPs), by interacting with actin, regulate the polymerization, depolymerization, bundling, and cross-linking of actin filaments, directly or indirectly, thereby mediating the maintenance of cell morphology, cell movement, and many other biological functions. Consequently, these functions of ABPs help regulate cancer cell invasion and metastasis when cancer occurs. In recent years, a variety of ABPs have been found to be abnormally expressed in various cancers, indicating that the detection and interventions of unusual ABP expression to alter this are available for the treatment of cancer. The early stages of most cancer development involve long-term chronic inflammation or repeated stimulation. This is the case for breast cancer, gastric cancer, lung cancer, prostate cancer, liver cancer, esophageal cancer, pancreatic cancer, melanoma, and colorectal cancer. This article discusses the relationship between chronic inflammation and the above-mentioned cancers, emphatically introduces relevant research on the abnormal expression of ABPs in chronic inflammatory diseases, and reviews research on the expression of different ABPs in the above-mentioned cancers. Furthermore, there is a close relationship between ABP-induced inflammation and cancer. In simple terms, abnormal expression of ABPs contributes to the chronic inflammation developing into cancer. Finally, we provide our viewpoint regarding these unusual ABPs serving as potential biomarkers for chronic inflammation-induced cancer diagnosis and therapy, and interventions to reverse the abnormal expression of ABPs represent a potential approach to preventing or treating the corresponding cancers.

Material Basis of the Difference between Hedysari Radix and Honey-Processed Hedysari Radix in Buzhong Yiqi.

OBJECTIVE: To compare the changes of chemical components of Hedysari Radix (HR) before and after honey-processing, and to explore the material basis of the difference between HR and honey-processed Hedysari Radix (HPHR) in Buzhong Yiqi. METHODS: Different compounds in aqueous extracts of HR and HPHR were analysed by UPLC-MS. A rat model of spleen qi deficiency was established. The rats were treated with different doses of water extracts of HR or HPHR, and pathological differences in spleen tissue, serum levels of D-xylose, gastrin (GAS) and amylase (AMS) interleukin-2 (IL)-2 and tumour necrosis factor-α (TNF-α), as well as spleen and thymus indices, were used as indicators. Differences in the efficacy of HR and HPHR in Buzhong Yiqi were studied. RESULTS: The research showed that compared with the blank group, the spleen tissue of rats in the model group showed spleen tissue damage, which mainly manifested as unclear boundaries between red pulp and white pulp, irregular spleen morphology and irregular arrangement, and the structure of white pulp destruction, less lymphocytes, the number of germinal centers decreased or atrophied. Compared with the model group, the middle and high dose groups of HR and HPHR had protective effects on spleen tissue of spleen-qi deficiency rats, and HPHR had a stronger effect; compared with those in the model group, rats in each treatment group showed remarkably higher serum D-xylose, GAS and AMS levels and thymus and spleen indices, and remarkably lower serum IL-2 and TNF-α levels, among which HPHR group showed better regulation effect than HR group. A total of 16 differential compounds were found in the aqueous extracts of HR and HPHR, of which 10 compounds in HPHR were up regulated, while 6 compounds were down regulated compare to HR. CONCLUSION: The results indicated that both HR and HPHR can improve spleen qi deficiency syndrome of rats, the pharmacodynamic effect of the latter was better than the former. Differences in components of HR and HPHR potentially leading to variations in efficacy.

[Comparative observation of acupoint thread-embedding and acupuncture therapy of Shugan Tiaoshen for insomnia of liver depression and qi stagnation].

OBJECTIVE: To compare the effect of Shugan Tiaoshen (soothing the liver and regulating mind) acupoint thread-embedding therapy and Shugan Tiaoshen acupuncture therapy for insomnia of liver depression and qi stagnation. METHODS: A total of 68 patients with insomnia of liver depression and qi stagnation were randomly divided into an acupoint embedding group (34 cases) and an acupuncture group (34 cases). Two groups were respectively treated with acupoint thread-embedding and acupuncture at Baihui (GV 20), Shenmen (HT 7), Neiguan (PC 6), Taichong (LR 3), Ganshu (BL 18) and Xinshu (BL 15). The treatment in the acupoint embedding group was given once a week, and in the acupuncture group was given once every other day for 6 weeks. The Pittsburgh sleep quality index (PSQI), self-rating anxiety scale (SAS), self-rating depression scale (SDS), TCM syndrome scores before and after treatment and medical expenses were compared between the two groups, and the clinical efficacy was evaluated. RESULTS: After treatment, the PSQI total scores, each sub-item score and SAS and SDS scores of the two groups were lower than those before treatment (P<0.05); the sleep quality, time during fall asleep, sleep time, sleep efficiency, daytime dysfunction scores and PSQI total score in the acupoint embedding group after treatment were lower than those in the acupuncture group (P<0.05). After treatment, except for constipation and yellowish urine, the sub-item scores and total scores of TCM syndromes in the two groups were lower than those before treatment (P<0.05); the sleep disturbance score of the acupoint embedding group was lower than that of the acupuncture group (P<0.05). The medical expenses in the acupoint embedding group was lower than that in the acupuncture group (P<0.05). The total effective rate of the acupoint embedding group was 85.3% (29/34), and the acupuncture group was 82.4% (28/34), there was no significant difference between the two groups (P>0.05). CONCLUSION: Shugan Tiaoshen acupoint thread-embedding therapy and Shugan Tiaoshen acupuncture therapy both have significant curative effect on insomnia of liver depression and qi stagnation, but acupoint thread-embedding therapy is better than acupuncture therapy in improving sleep quality and reducing medical expenses.

[Acupuncture Intervention Improves Behavior Reactions and Learning-memory Ability in Post-traumatic Stress Disorder Rats].

OBJECTIVE: To observe the therapeutic effect of acupuncture in the treatment of post-traumatic stress disorder (PTSD)-induced abnormal behavior reactions and learning-memory ability in rats with traumatic injury. METHODS: Sixty male SD rats were randomly divided into control, model, model＋animal capturing (capturing), medication and acupuncture groups (n＝12 rats in each). The PTSD model was established by "electric shock plus incarceration" method. Acupuncture was applied to "Baihui" (GV 20), and unilateral "Neiguan" (PC 6), "Shenmen" (HT 7) and "Taichong" (LR 3) once daily for 12 days. The rats in the medication group were treated by gavage of Paroxetine Hydrochloride solution (0.42 mg/mL), once daily for 12 days. The open field test containing horizontal (crossing grid lines) and rearing tests was performed for examining the rats' locomotor activity and anxiety-like behavior; and location navigation (escape latency) and special probe tests (platform quadrant crossing times) of Morris water maze tasks were detected for assessing the rats' learning-memory ability. On day 12 of the experiments, the rats were submitted to 3 consecutive sessions of open field tests for observing the time of familiar objects (TF) and the time of novelty object (TN) of exploration in 5 min (an object-location and an object-recognition tasks), followed by calculating the discrimination index [DI＝(TN－TF)/(TN＋TF)x100%]. RESULTS: After modeling, compared with the control group, the numbers of crossed grids and rearing, and DI were significantly decreased (P<0.05), while the number of fecal pellets and escape latency were significantly increased in both the model and capturing groups (P<0.05). After the intervention, the number of both crossed grids and rearing, platform quadrant crossing times, and DI were considerably increased (P<0.05), and the rats' escape latency and fecal pellet number were obviously decreased in both medication and acupuncture groups relevant to the model and capturing groups (P<0.05). No significant differences were found between the acupuncture and medication groups in the above mentioned 5 indexes (P>0.05)．. CONCLUSION: Acupuncture can effectively reduce anxiety-like behavior and improve the impaired learning-memory ability in PTSD rats.

[Progress of the Mechanism of Acupuncture to Promote Repair of Facial Nerve Injury].

Facial nerve injury results in facial muscle movement disorders that interferes with patient's life. Acupuncture is an effective therapy for facial nerve injury, but its mechanism has not been clarified. The evidence supports that acupuncture can accelerate the repair of facial nerve injury by adjusting the electric wave of patient's facial muscle, improving facial blood circulation, and promoting the expression of cell and protein molecule.

[Review on Modern Repair Mechanism of Moxibustion for Treating Inflammatory Damage of Rheumatoid Arthritis].

Rheumatoid arthritis (RA) is a chronic inflammatory disease. Persistent inflammation of the synovial membrane is the main characteristic pathological symptom. Moxibustion for treating RA has achieved significant clinical effect in recent years. A large number of experimental studies have also shown that moxibustion promoted the repair of inflammatory damage induced by RA. Based on summarizing 10 years related literatures, the authors analyzed the repair mechanisms of moxibustion for inflammatory damage in RA from central mechanisms including glucocorticoid receptor, melatonine, hypothalamic-pituitary-adrenal axis, and cholinergic nerve to peripheral mechanisms including local inflammatory mediators, cytokine, and inflammatory cell signaling pathway, so as to provide evidences and reference for further research.

[Clinical assessment of chronic prostatitis based on infrared imaging technology].

OBJECTIVE: To investigate the characteristic changes in the infrared thermogram of chronic prostatitis (CP) patients and find some evidence for the auxiliary diagnosis and therapeutic evaluation of the disease. METHODS: Fifty CP patients and 20 healthy male volunteers were included in this clinical trial. The infrared thermograms of the subjects were compared between the two groups for characteristic changes. The values obtained were used for the auxiliary diagnosis and therapeutic evaluation of the disease. RESULTS: Compared with the healthy males in the same age group, the CP patients showed extremely significant abnormal changes in the average temperature value in the hypogastrium (H), pubis (P), scrotum (S), and groin (G) (P < 0.01). The average H temperature value of the CP patients was correlated negatively with the CP symptom index (CPSI) (P < 0.01, Pearsons correlation coefficient = -0.519), while the S temperature positively with CPSI (P < 0.01, Pearsons correlation coefficient = 0.446). In addition to the H value, the P, S, and G values were all correlated in different degrees with CPSI (P < 0.01), which the S value exhibited the most significantly negative correlation (Pearson's correlation coefficient = -0.898). CONCLUSION: There are some characteristic changes in the hypogastrium temperature of CP patients in the infrared thermogram, which has a potential application value for the auxiliary diagnosis, symptom assessment, and therapeutic evaluation of CP.

Deprivation amblyopia model was established by monocular eyelid suture in the model group and acupuncture group. Acupuncture was applied at "Jingming" (BL 1), "Chengqi" (ST 1), "Qiuhou" (EX-HN 7) and "Cuanzhu" (BL 2) in the acupuncture group. The bilateral acupoints were selected alternately, one side for a day, and totally 14 days were required. The effect of acupuncture on visual evoked potential in different spatial frequencies was observed. METHODS: Under three different kinds of spatial frequencies of 2 X 2, 4 X 4 and 8 X 8, compared with normal group, there was obvious visual deprivation effect in the model group where P1 peak latency was delayed (P<0.01) while N1 -P1 amplitude value was decreased (P<0.01). Compared with model group, P1 peak latency was obviously ahead of time (P<0.01) while N1-P1 amplitude value was increased (P<0.01) in the acupuncture group, there was no statistical significance compared with normal group (P>0.05). Under spatial frequency of 4 X 4, N1-P1 amplitude value was maximum in the normal group and acupuncture group. With this spatial frequency the rat's eye had best resolving ability, indicating it could be the best spatial frequency for rat visual system. CONCLUSION: The visual system has obvious electrophysiology plasticity in sensitive period. Acupuncture treatment could adjust visual deprivation-induced suppression and slow of visual response in order to antagonism deprivation effect.
