Classification Algorithm-Based fMRI Images for Evaluating the Effect of Yishen Tiaodu Acupuncture on the Recovery Period of Cerebral Infarction.

This study aimed to explore the application value of multifeature fusion classification algorithm based on deep learning and Yishen Tiaodu acupuncture in the diagnosis and treatment of patients with cerebral infarction in convalescence. Methods. 62 patients with cerebral infarction were randomly classified into the experimental group and the control group, with 31 patients in each group. All patients received the functional magnetic resonance imaging (fMRI) examination. The image processing method was the multifeature fusion classification algorithm based on deep learning. DICE coefficient, accuracy, and sensitivity were used to evaluate the image processing performance of traditional and new algorithms. Patients in the experimental group were treated with Yishen Tiaodu acupuncture, while patients in the control group were treated with ordinary acupuncture. The evaluation of the cyberchondria severity scale (CSS) and the activities of daily living (ADL) was performed at enrollment, 15 days after treatment, 28 days after treatment, and 1 month after treatment. The results showed that the quality of fMRI images processed by multifeature fusion classification algorithm based on deep learning was signally improved. The clinical efficacy of the traditional Chinese medicine (TCM) syndrome score (86.7% vs. 60.9%) and neurological impairment score (83.4% vs. 53.5%) in the experimental group were remarkably higher compared with the control group (P < 0.05). After treatment, the TCM syndrome score of the experimental group was markedly lower than that of the control group, while the ADL score was higher (P < 0.05). Conclusion. The performance of multifeature fusion classification algorithm based on deep learning in fMRI image processing of patients with cerebral infarction is better than that of traditional algorithms. Yishen Tiaodu acupuncture has a good therapeutic effect on the recovery of motor and neurological function in patients with cerebral infarction at convalescence.

Altered fractional amplitude of low-frequency fluctuation in women with premenstrual syndrome via acupuncture at Sanyinjiao (SP6).

BACKGROUND: Premenstrual syndrome (PMS) is a prevalent gynecological disease and is significantly associated with abnormal neural activity. Acupuncture is an effective treatment on PMS in clinical practice. However, few studies have been performed to investigate whether acupuncture might modulate the abnormal neural activity in patients with PMS. Thereby, the aim of the study was to assess alterations of the brain activity induced by acupuncture stimulation in PMS patients. METHODS: Twenty PMS patients were enrolled in this study. All patients received a 6-min resting-state functional magnetic resonance imaging (rs-fMRI) scan before and after electro-acupuncturing stimulation (EAS) at Sanyinjiao (SP6) acupoint in the late luteal phase of menstrual. Fractional amplitude of low-frequency fluctuation (fALFF) method was applied to examine the EAS-related brain changes in PMS patients. RESULTS: Compared with pre-EAS at SP6, increased fALFF value in several brain regions induced by SP6, including brainstem, right thalamus, bilateral insula, right paracentral lobule, bilateral cerebellum, meanwhile, decreased fALFF in the left cuneus, right precuneus, left inferior temporal cortex. CONCLUSIONS: Our findings provide imaging evidence to support that SP6-related acupuncture stimulation may modulate the neural activity in patients with PMS. This study may partly interpret the neural mechanisms of acupuncture at SP6 which is used to treat PMS patients in clinical. TRIAL REGISTRATION: The study was registered on http://www.chictr.org.cn .

Regulated aberrant amygdala functional connectivity in premenstrual syndrome via electro-acupuncture stimulation at sanyinjiao acupoint（SP6）.

Background: Acupuncture is an effective therapy for premenstrual syndrome (PMS). However, the mechanisms behind this method are still unclear. Our previous study found that aberrant amygdala resting-state functional networks were involved in PMS. Thereby, a deep investigation on the alterations of amygdala resting-state functional networks induced by acupuncture stimulation might contribute to a better understanding of the intricate mechanisms of acupuncture treatment on PMS. Methods: Twenty three PMS patients were recruited in this study. All patients received a 6-minute electro-acupuncture stimulation (EAS) at Sanyinjiao acupoint (SP6) and underwent two 6-minute resting-state fMRI scannings before and after EAS. With amygdala as the seed region, functional connectivity (FC) method was adopted to examine EAS-related modulation of intrinsic connectivity in PMS patients by comparing pre-EAS. Results: The results showed that EAS at SP6 induced increased FC between the left amygdala and brainstem, right hippocampus, and decreased FC between the left amygdala and left thalamus, bilateral supplementary motor area (SMA). Moreover, the results also showed that EAS at SP6 induced increased FC between the right amygdala and brainstem, right hippocampus, right orbitofrontal cortex, bilateral anterior cingulate cortex (ACC), and decreased FC between the right amygdala and right SMA. Conclusions: Based on the results of our previous study, our findings might improve our understanding of neural mechanisms behind acupuncture effects on PMS.

Fire-needle acupuncture for upper limb spastic paralysis after stroke: Study protocol for a randomized controlled trial.

BACKGROUND: Fire-needle acupuncture, an important kind of acupuncture therapy, has been clinically used to treat upper limb spastic paralysis (ULSP) after stroke. Clinical experience has indicated that fire-needle acupuncture treatment takes less time, requires fewer visits, and has more rapid results and fewer side effects compared to chemical medicine alternatives. This study will evaluate the effects of fire-needle acupuncture for ULSP in the context of standardized clinical research and provide high-quality data to inform clinical procedures and future study design. METHODS/DESIGN: A randomized controlled trial will be carried out to evaluate the effects of fire-needle acupuncture therapy in patients with ULSP from stroke. ULSP patients (n = 120) will be recruited at Changhai Hospital in Shanghai, China. Patients will be randomly divided into three groups, including fire-needle acupuncture group (FAG), filiform-needle acupuncture group (FFAG) and rehabilitation treatment group (RTG). During the 3-week treatment, the FAG will be treated every two days, while FFAG and RTG will be treated 5 d in a row and then rest for 2 d. The Simplified Fugl-Meyer Motor Function Scale and Modified Ashworth Scale will be used as the primary outcome measures. Statistical analysis will be conducted by an independent statistician. DISCUSSION: Through this study, the utility of fire-needle acupuncture in treating ULSP after stroke will be tested, and some specific claims of fire-needle acupuncture therapy will be evaluated, such as relieving spasm and muscular tension, improving activities of daily living, rapidity of response and less frequency of treatment compared with other treatments.

Altered Brain Regional Homogeneity Following Electro-Acupuncture Stimulation at Sanyinjiao (SP6) in Women With Premenstrual Syndrome.

Background: Premenstrual syndrome (PMS) is a menstrual cycle-related disorder which causes physical and mood changes prior to menstruation and is associated with the functional dysregulation of the brain. Acupuncture is an effective alternative therapy for treating PMS, and sanyinjiao (SP6) is one of the most common acupoints used for improving the symptoms of PMS. However, the mechanism behind acupuncture's efficacy for relieving PMS symptoms remains unclear. The aim of this study was to identify the brain response patterns induced by acupuncture at acupoint SP6 in patients with PMS. Materials and Methods: Twenty-three females with PMS were enrolled in this study. All patients underwent resting-state fMRI data collection before and after 6 min of electroacupuncture stimulation (EAS) at SP6. A regional homogeneity (ReHo) approach was used to compare patients' brain responses before and after EAS at SP6 using REST software. The present study was registered at http://www.chictr.org.cn, and the Clinical Trial Registration Number is ChiCTR-OPC-15005918. Results: EAS at SP6 elicited decreased ReHo value at the bilateral precuneus, right inferior frontal cortex (IFC) and left middle frontal cortex (MFC). In contrast, increased ReHo value was found at the bilateral thalamus, bilateral insula, left putamen and right primary somatosensory cortex (S1). Conclusions: Our study provides an underlying neuroimaging evidence that the aberrant neural activity of PMS patients could be regulated by acupuncture at SP6.

Unconventional Superconductivity in the Layered Iron Germanide YFe(2)Ge(2).

The iron-based intermetallic YFe_{2}Ge_{2} stands out among transition metal compounds for its high Sommerfeld coefficient of the order of 100 mJ/(mol K^{2}), which signals strong electronic correlations. A new generation of high quality samples of YFe_{2}Ge_{2} show superconducting transition anomalies below 1.8 K in thermodynamic, magnetic, and transport measurements, establishing that superconductivity is intrinsic in this layered iron compound outside the known superconducting iron pnictide or chalcogenide families. The Fermi surface geometry of YFe_{2}Ge_{2} resembles that of KFe_{2}As_{2} in the high pressure collapsed tetragonal phase, in which superconductivity at temperatures as high as 10 K has recently been reported, suggesting an underlying connection between the two systems.

[Acupuncture and moxibustion based on meridian differentiation for cervical spondylosis radiculopathy:a randomized controlled trial].

OBJECTIVE: To observe the difference of clinical effects of acupoints selected based on meridian differen-tiation and conventional method for cervical spondylosis radiculopathy(CSR) treated with acupuncture and moxibustion. METHODS: Sixty patients with CSR were randomly divided into an observation group and a control group,30 cases in each one. Ashi points of the injured meridians in the neck,namely six-he points,were selected in the observation group,matched with luo-connecting points of the injured meridians on the same side and the interiorly-exteriorly correlated meridians on the opposite side. Conventional acupuncture was used on Fengchi(GB 20),Jiaji(EX-B 2) of the neck,Tianzhu(BL 10),Jianjing(GB 21),Houxi(SI 3),Hegu(LI 4) and Waiguan(TE 5) on the affected side in the control group. Treatment was given once every other day,three times a week and total 12 times in the two groups. Twenty subscales for CSR and visual analogue scale(VAS) were observed before and after treatment,and total effects were evaluated after treatment. RESULTS: The effective rate of the observation group was 93.3%(28/30),which was better than 66.7%(20/30) of the control group(P<0.05). The scores of 20 subscales and VAS after treatment were all improved compared with those before treatment in the two groups(all P<0.01),with more apparent change in the observation group(both P<0.05). CONCLUSIONS: The effect of acupuncture and moxibustion based on meridian differentiation is obvious,and superior to that of conventional acupoints selection.

[Comparative study on hypoglycemic effects of different traditional Chinese medicine treatments in rats with diabetes mellitus induced by alloxan].

OBJECTIVE: To observe hypoglycemic effects of Yunu Decoction, Zuogui Pill and Shenqi Pill, three compound traditional Chinese herbal medicines, in treatment of diabetes mellitus induced by alloxan in rats, and to compare the therapeutic effects among the three recipes for nourishing yin, clearing away heat, and nourishing yin and warming yang. METHODS: Diabetes mellitus was induced in rats with alloxan at a dose of 60 mg/kg via tail vain injection. The diabetic rats were randomly divided into four groups: alloxan model group, Yunu Decoction-treated group, Zuogui Pill-treated group and Shenqi Pill-treated group. Rats in the three recipe groups were administered intragastrically with water extraction of Yunu Decoction, Zuogui Pill, and Shenqi Pill accordingly for 10 days. Then the level of blood glucose was measured by glucose oxidase method and the glucose tolerance was determined. RESULTS: Compared with the normal rats, blood glucose level in the alloxan model group was obviously increased (P<0.05). Glucose levels in the three recipe groups were obviously decreased as compared with the alloxan model group (P<0.05), and glucose level in the Yunu Decoction-treated group after treatment was significant lower than before treatment (P<0.05). The glucose tolerance test indicated that rats in the alloxan model and three recipe groups revealed impaired glucose tolerance as compared with the normal rats, and there were no significant differences between the alloxan model group and the three recipe groups. CONCLUSION: Yunu Decoction, Zuogui Pill and Shenqi Pill can effectively decrease the glucose level of the rats with diabetes mellitus induced by alloxan, and Yunu Decoction showed the best therapeutic effects. The glucose tolerance test shows that the three recipes cannot correct the abnormal metabolism of glucose.
