ABSTRACT
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-3β (GSK-3β) 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-3βwas 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-3β 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-3β and the up-regulation of PP2A in the hippocampus, and then to inducing the inhibition of tau protein phosphorylation.

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@#This study aimed to determine the effect of radiotherapy (RT) on the risk of herpes zoster (HZ) in patients with gynecological cancers via a nationwide population-based study. @*Methods@#Based on patient data obtained from the National Health Insurance Research Database, 1928 gynecological cancer patients were identified with 1:1 matching for RT and non-RT cohorts by age, index date, and cancer type. Another cohort consisting of 964 noncancer individuals matched was used as normal control. The incidence of HZ was compared between cancer patients with and without RT. Age, comorbidities, cancer-related surgery and chemotherapy (CT), and cancer type were adjusted as confounders. @*Results@#The risk of HZ in cancer patients was higher than that of non-cancer individuals (14.23 versus 8.34 per 1,000 person-years [PY], the adjusted hazard ratio [aHR]=1.38, p=0.044). In the cancer population, the incidence of HZ for the RT and non-RT cohorts was 20.55 versus 10.23 per 1,000 PY, respectively (aHR=1.68, p=0.009). Age >50 years was an independent factor for developing HZ. The 5-year actuarial incidence for patients receiving neither RT nor CT, RT alone, CT alone, and combined modalities was 5.4%, 6.9%, 3.7%, and 9.9%, respectively (p<0.001). In the RT cohort, the risk rose rapidly in the first year, becoming steady thereafter. @*Conclusion@#This population-based study showed that gynecological cancer patients receiving RT combined with CT had the highest cumulative risk of HZ. Health care professionals should be aware of the potential toxicities.

Reducing ROS level by antioxidant drugs to protect cardiomyocytes is being the spotlight on MIRI treatment. In this review, the research progress of antioxidant drugs in myocardial ischemia-reperfusion injury in recent years was summarized.
ABSTRACT
Objective Alzheimer's disease (AD) is the most common cause of dementia. The pathophysiology of the disease mostly remains unearthed, thereby challenging drug development for AD. This study aims to screen high throughput gene expression data using weighted co-expression network analysis (WGCNA) to explore the potential therapeutic targets.Methods The dataset of GSE36980 was obtained from the Gene Expression Omnibus (GEO) database. Normalization, quality control, filtration, and soft-threshold calculation were carried out before clustering the co-expressed genes into different modules. Furthermore, the correlation coefficients between the modules and clinical traits were computed to identify the key modules. Gene ontology and pathway enrichment analyses were performed on the key module genes. The STRING database was used to construct the protein-protein interaction (PPI) networks, which were further analyzed by Cytoscape app (MCODE). Finally, validation of hub genes was conducted by external GEO datasets of GSE 1297 and GSE 28146.Results Co-expressed genes were clustered into 27 modules, among which 6 modules were identified as the key module relating to AD occurrence. These key modules are primarily involved in chemical synaptic transmission (GO:0007268), the tricarboxylic acid (TCA) cycle and respiratory electron transport (R-HSA-1428517).
ABSTRACT
Objective:To observe the effect of liver-soothing and mind-regulating acupuncture method on the resting-state electroencephalography (EEG) in rats with post-traumatic stress disorder (PTSD),and to provide evidence for the effect mechanism study and clinical application of acupuncture intervention for PTSD.Methods:Sixty Sprague-Dawley (SD) rats were randomly divided into a blank control group,a model group,a grasping group,a paroxetine group and an acupuncture group,with 12 rats in each group.Except for rats in the blank control group,rats in the other groups were subjected to preparing the PTSD models using 'incarceration plus electric shock' method.After interventions,changes in rat behavior of each group were observed;changes in resting-state EEG were collected and analyzed with multichannel EEG acquisition and analysis system,and image analysis and statistical processing were performed.Results:Compared with the blank control group,the average escape latency in the model group was significantly longer (P＜0.05),and the times of crossing the platform and the effective areas were all significantly reduced (P＜0.01).Compared with the grasping group,the average escape latencies in the paroxetine group and acupuncture group were significantly shortened (P＜0.05),and the times of crossing the platform and the effective areas were all significantly increased (P＜0.05).There were no significant differences in the average escape latency,the times of crossing the platform and the effective areas between the acupuncture group and paroxetine group (all P＞0.05).Compared with the blank control group,the α-wave power spectrum value in the model group was significantly decreased,and the power spectrum values of β-wave,δ-wave and a-wave were significantly increased (all P＜0.01);compared with the grasping group,α-wave power spectrum values in the paroxetine group and acupuncture group were significantly increased (both P＜0.01),and the power spectrum values of β-wave,δ-wave and a-wave were decreased significantly (all P＜0.01).The power spectrum values of α-wave,β-wave,δ-wave and (e)-wave of rats in the acupuncture group were not significantly different from those in the paroxetine group (all P＞0.05).Conclusion:Liver-soothing and mind-regulating acupuncture method can significantly improve the abnormal EEG activity in PTSD rats,which may be one mechanism of liver-soothing and mind-regulating acupuncture method in effectively affecting the brain function in PTSD rats.

ABSTRACT
Objective To investigate the effects of different stimulation of electroacupuncture on the protein expressions of SOCS1 and SOCS3 in rabbits with acute facial nerve injury; To determine the better stimulation. Methods New Zealand rabbits were treated with special hemostatic forceps for 5 min, and the length of the lesion was about 2.5 cm. The model of facial nerve injury was induced. The experiment was divided into blank group, sham-operation group, model group, and electoracupuncture weak-, medium-, and strong-stimulation group. The model group received no intervention after surgery. After treatment, the damaged facial nerve of each group was intercepted. The protein expressions of SOCS1 and SOCS3 mediated by negative feedback regulation of JAK-STAT were detected by ABC-ELISA. Results Compared with the blank group, the protein expressions of SOCS1 and SOCS3 in the model group increased (P<0.01). Compared with the model group, the protein expressions of SOCS1 and SOCS3 protein in electroacupuncture weak- stimulation group decreased (P<0.01). Conclusion Electroacupuncture can make SOCS1, SOCS3 protein expressions normal for acute facial nerve injury, and acupuncture treatment effect does not increase with the increase of stimulation.
