Spontaneous pregnancy after thread-embedding therapy treatment with premature ovarian insufficiency after unilateral oophorectomy: a case report.

Premature ovarian insufficiency (POI) is a condition characterized by menstrual disturbance, subfertility, and estrogen deficiency symptoms. Women with POI have a small chance of natural conception, which may be even smaller when complicated with unilateral ovarian due to reduction of the ovarian follicular reserve. In China, acupuncture has been widely used to treat POI and POI-induced infertility, and studies have shown that acupuncture is helpful for improving ovarian function. Thread-embedding therapy is a method of acupuncture treatment development and extension, which can make the acupuncture effect last. In this article, we report a patient diagnosed with POI after unilateral oophorectomy (UO) who spontaneously conceived after thread-embedding therapy. Thread-embedding therapy may improve ovarian function in patients with POI, thereby providing a treatment strategy for infertility in patients with POI. This case report was written in accordance with the CARE guidelines.

Exploring the association between Frailty Index and low back pain in middle-aged and older Chinese adults: a cross-sectional analysis of data from the China Health and Retirement Longitudinal Study (CHARLS).

OBJECTIVES: This study explored the association between the Frailty Index (FI) and low back pain (LBP) in middle-aged and older Chinese adults. We hypothesised that a higher FI correlates with increased LBP prevalence. DESIGN: Cross-sectional analysis. SETTING: The study used data from the China Health and Retirement Longitudinal Study (CHARLS) across various regions of China. PARTICIPANTS: The analysis included 6375 participants aged 45 and above with complete LBP and FI data from the CHARLS for 2011, 2013 and 2015. We excluded individuals under 45, those with incomplete LBP data, participants with fewer than 30 health deficit items and those missing covariate data. OUTCOME MEASURES: We constructed an FI consisting of 35 health deficits. Logistic multivariable regression examined the relationship between FI and LBP, using threshold analysis to identify inflection points. Sensitivity analyses were performed to ensure the robustness of the findings. RESULTS: Of the participants, 27.2% reported LBP. A U-shaped association was observed between FI and LBP, with the highest quartile (Q4, FI ≥0.23) showing more than a twofold increased risk of LBP (OR=2.90, 95% CI: 2.45-3.42, p<0.001). Stratified analysis showed a significant association in participants under 60, particularly in the lowest FI quartile (OR=1.43, 95% CI: 1.14 to 1.79). Sensitivity analysis upheld the robustness of the primary results. CONCLUSIONS: The findings suggest a complex relationship between frailty and LBP, highlighting the need for early screening and tailored interventions to manage LBP in this demographic. Further research is necessary to understand the mechanisms of this association and to validate the findings through longitudinal studies.

Exploring the association between dietary Inflammatory Index and chronic pain in US adults using NHANES 1999-2004.

Chronic pain, a substantial public health issue, may be influenced by dietary patterns through systemic inflammation. This cross-sectional study explored the association between Dietary Inflammatory Index (DII) and chronic pain among 2581 American adults from NHANES data. The DII, ranging from - 4.98 to 4.69, reflects the inflammatory potential of the diet, with higher scores indicating greater pro-inflammatory capacity. Our findings showed no significant association between the continuous DII score and chronic pain prevalence. However, a nonlinear relationship emerged. When the DII was categorized, a significant association between higher DII scores (DII ≥ 2.5) and chronic pain prevalence was observed. The analysis uncovered a U-shaped pattern, with an inflection point at a DII score of - 0.9, indicating an association between both low and high levels of dietary inflammation are associated with higher pain prevalence. This nuanced interaction between dietary inflammation and chronic pain indicates the possibility of incorporating dietary modification into pain management strategies and underscores the need for further research into the long-term effects of diet on chronic pain.

Current state of research on exercise for the treatment of myasthenia gravis: A scoping review.

OBJECTIVE: To provide a comprehensive overview of existing evidence, research gaps, and future research priorities concerning the treatment of myasthenia gravis (MG) using exercise therapies. METHOD: Clinical studies on exercise treatment for MG were searched in nine databases to conduct a scoping review. Two independent researchers screened the literature and comprehensively analyzed the characteristics and limitations of the included articles. RESULTS: A total of 5725 studies were retrieved, of which 24 were included. The included studies were conducted in 16 different countries/regions and 456 patients were enrolled. Study designs included both interventional and observational studies. Exercise interventions included aerobic exercise, resistance exercise, balance training, and stretch training, and are typically administered in conjunction with medication, usual care, or some other interventions. The intensity, frequency, and duration of exercise interventions varied hugely among studies. Six-minute walk test, adverse events, muscle strength, MG quality of life-15 scale, forced vital capacity, quantitative MG scale, and MG activities of daily living scale were the most frequently used outcomes. All studies reported results in favor of the efficacy and safety of exercise in MG, and exercise-related adverse events were reported in two studies. CONCLUSION: This scoping review provides an overview of the evidence concerning exercise treatment for MG. Key gaps in evidence include a limited number of participants, complex interventions, variability in outcome selection, and insufficient reporting in publications. The promotion of exercise treatment for MG still encounters several obstacles. A larger population, rigorous study design and conduction, standardized interventions and outcomes, and standardized reporting are essential.

The impact of "long COVID" on menstruation in Chinese female college students and the intervention of acupuncture.

This study aimed to explore the potential application value of acupuncture in alleviating the impact of long COVID on women's menstrual cycles, by investigating the occurrence of long COVID among female college students, its effects on menstruation, and the intervention of acupuncture. This cross-sectional study surveyed female college students with a history of coronavirus disease 2019 (COVID-19) before April 10, 2023. A questionnaire was used to analyze demographic characteristics, post-COVID sequelaes, duration of symptoms, and treatments received during that period. Among the 731 participants enrolled in the survey, 468 were female undergraduate students who met the analysis criteria. Among them, 85 individuals fit the definition of "Long COVID" (18.16%). Within the group of patients with long COVID, 69 individuals experienced changes in their overall menstrual patterns compared to the 6 months prior to contracting the novel coronavirus (81.18%). Additionally, 17 individuals opted for acupuncture treatment following the onset of COVID-19 (20.00%), which resulted in less impact on their menstrual cycle (41.18% vs 64.71% without receiving acupuncture, OR = 2.62), menstrual period duration (41.18% vs 64.71%, OR = 2.62), menstrual flow (47.06% vs 69.18%, OR = 2.52), and the color of menstrual blood (41.18% vs 63.24%, OR = 2.46) among these patients. Long COVID had a certain impact on menstruation. Acupuncture potentially alleviates the clinical symptoms of long COVID and reduces its impact on women's menstrual cycle, thus having potential therapeutic value in the treatment of long COVID.

OBJECTIVES: To compare the effect of different frequency of acupoint thread-embedding on weight loss in subjects with overweight/obesity of spleen deficiency and dampness retention. METHODS: A total of 126 subjects with overweight/obesity of spleen deficiency and dampness retention were randomized into a 2-week group(63 cases, 13 cases dropped out)and a 3-week group(63 cases, 11 cases dropped out, 1 case was eliminated). The two groups were treated with acupoint thread-embedding once every 2 weeks and once every 3 weeks respectively, Zhongwan(CV 12), Shuifen(CV 9), Qihai(CV 6), Guanyuan(CV 4) and bilateral Zhangmen(LR 13), Tianshu(ST 25), Liangmen(ST 21), Daheng(SP 15), Fujie(SP 14), Pishu(BL 20), Yinlingquan(SP 9)were selected. Four times were required in the two groups. Before and after treatment, follow-up after 2 months of treatment completion, the body mass index(BMI), body weight, waist circumference, hip circumference, waist-to-hip ratio, obesity degree, fat percentage(F%), skin fold thickness were observed in the two groups. RESULTS: After treatment and in follow-up, the BMI, body weight, waist circumference, hip circumference, waist-to-hip ratio, obesity degree, F%, skin fold thickness in the two groups were decreased compared with those before treatment (P<0.001, P<0.01), the changes of BMI, body weight, obesity degree, F%, skin fold thickness in the 2-week group were larger than those in the 3-week group(P<0.05, P<0.01, P<0.001). CONCLUSIONS: The effect of acupoint thread-embedding once every 2 weeks on weight loss in subjects with overweight/obesity of spleen deficiency and dampness retention is superior to that once every 3 weeks.

Acupuncture for autophagy in animal models of middle cerebral artery occlusion: A systematic review and meta-analysis protocol.

INTRODUCTION: Ischemic stroke has high morbidity, disability and mortality rates. The effective treatments recommended by guideline have considerable limitations due to their strict range of adaptation and narrow time window. Acupuncture is an effective and safe treatment for ischemic stroke, and the mechanism may be related to autophagy. In this systematic review, we aim to summarize and evaluate the evidence of autophagy in acupuncture therapy for animal models of middle cerebral artery occlusion (MCAO). METHODS: Publications will be retrieved from the MEDLINE, Embase, Cochrane Library, Web of Science, CNKI, CBM, CVIP and Wanfang databases. We will include animal experimental studies of acupuncture for MCAO, and the control group will receive placebo/sham acupuncture or no treatment after model establishment. Outcome measures must include autophagy and will include neurologic scores and/or infarct size. The Systematic Review Center for Laboratory animal Experimentation (SYRCLE) risk of bias tool will be used to assess the risk of bias. A meta-analysis will be performed if the included studies are sufficiently homogenous. Subgroup analyses will be conducted according to different intervention types and different types of outcomes. Sensitivity analyses will also performed to explore the heterogeneity and to assess the stability of the results. Publication bias will be assessed by funnel plots. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system will be applied to evaluate the quality of evidence in this systematic review. DISCUSSION: The results of this study may help to explain autophagy in acupuncture therapy for ischemic stroke. The limitation of this review is that all included studies will be retrieved from Chinese or English medical databases due to language barriers. REGISTRATION: We registered in PROSPERO on May 31, 2022. (https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=329917) (CRD42022329917).

Mapping current trends and hotspots in myasthenia gravis from 2003 to 2022: a bibliometric analysis.

Introduction: Research on myasthenia gravis (MG) has undergone rapid development in recent years. This article aimed to elucidate the characteristics of MG publications over the past 20 years and analyze emerging trends using bibliometric methods. Methods: Information on MG articles was obtained from the Web of Science Core Collection and stored in Excel for quantitative analyses. Bibliometric analyses were performed using CiteSpace and VOSviewer to visualize publications according to countries/regions, institutions, journals, and authors. Results: A total of 3,610 publications were included in the analysis. The USA had the highest number of publications (NP) and H-index. Among the institutions, the University of Oxford had the highest NP, followed by the University of Toronto and Duke University. Close cooperation was observed among countries and institutions. The most productive author was Renato Mantegazza, followed by Jan J. Verschuuren, and Amelia Evoli. Muscle & Nerve published the most articles on MG, followed by the Journal of Neuroimmunology and Neuromuscular Disorders. The keyword with the highest strength is "neuromuscular transmission," followed by "safety" and "rituximab." Co-citation analysis includes 103 publications cited at least 65 times, categorized into four clusters. Additionally, 123 keywords cited more than 40 times were analyzed and divided into five clusters. Conclusion: This bibliometric analysis shows the framework of research over the past 20 years by mapping the scholarly contributions of various countries or regions, institutions, journals, and authors in MG. The analysis also explores future trends and prospective directions, emphasizing individualized treatment based on subtypes, novel immunotherapeutic approaches, and thymectomy.

Herbal medicine and acupuncture relieved progressive bulbar palsy for more than 3 years: A case report.

RATIONALE: Progressive bulbar palsy (PBP) is a type of motor neuron disease (MND). The main symptoms include dysarthria, dysphagia, tongue muscle atrophy and fasciculations. This disease is generally severe and develops rapidly. Due to the lack of effective treatment, many patients with MND in China turn to traditional Chinese medicine treatment for help. We successfully relieved dysphagia and sialorrhea in a patient with PBP for 3 years with herbal medicine and acupuncture. PATIENT CONCERNS: The patient was a 68-years-old woman with PBP and suffered from severe dysphagia and sialorrhea. DIAGNOSES: Progressive bulbar palsy. INTERVENTIONS: Chinese herbal medicine and acupuncture. OUTCOMES: After 4 months of herbal medicine and acupuncture treatment, dysphagia and sialorrhea were relieved considerably. The patient's condition has been stable for more than 3 years and continues to be treated with Chinese herbal medicine and acupuncture. LESSONS: Our case suggests that alternative therapies such as herbal medicine and acupuncture may be effective in alleviating the symptoms of MND/PBP. However, standardized clinical studies are still required to verify the effectiveness and safety.

Current state of research on acupuncture for the treatment of amyotrophic lateral sclerosis: A scoping review.

Objective: To provide an overview of the range and characteristics of existing evidence, research gaps, and future research priorities in treating amyotrophic lateral sclerosis (ALS) with acupuncture. Method: Clinical studies on acupuncture treatment for ALS were searched in 9 databases and two websites. Two independent researchers screened the literature according to the inclusion and exclusion criteria; extracted the demographic data, interventions, and significant findings of the studies; and comprehensively analyzed the characteristics and limitations of the included articles. Results: A total of 2,326 studies were retrieved, of which 92 were included. Most of the studies were conducted in China, with the number increasing over time. Study designs included case reports, case series, randomized controlled trials (RCTs), and before-and-after studies, among which case reports were the most frequently used. A total of 1,388 patients were enrolled, of whom 1,031 had ALS, 274 had progressive bulbar palsy (PBP), 60 had progressive muscle atrophy (PMA), and 23 had primary lateral sclerosis (PLS). Acupuncture interventions included body acupuncture, electroacupuncture, acupoint injection, scalp acupuncture, acupoint massage, Sa-am acupuncture, needle-embedding therapy, auricular acupuncture, venom pharmacopuncture therapy, plum blossom needling, acupoint paste, electroacupuncture, and needle warming through moxibustion. The most frequently used acupoints were ST36, LI4, SP6, and LI11. Acupuncture is often applied in combination with other treatments, such as herbal or Western medicine. The frequency of treatment ranged from once a month to three times a day, and the duration of treatment ranged from 5 days to 3 years. Clinical symptoms, muscle strength, and effective rates were the most frequently used outcomes. Most studies reported significant efficacy, and only a few studies reported adverse events explicitly. Conclusion: Evidence gaps include poor study design, complex interventions, limited significance of the selected outcomes, and limited study reporting. The promotion of acupuncture treatment for ALS still faces several obstacles. Rigorous study design and conduct, standardized intervention and outcome measurements, and normative reporting are needed to investigate the efficacy and safety of acupuncture treatment for ALS.

[Tongdu Xingshen acupuncture and moxibustion combined with cognitive training in treatment of post-stroke mild cognitive impairment: a randomized controlled trial].

OBJECTIVE: To compare the clinical effect of Tongdu Xingshen (promoting the governor vessel and regaining consciousness) acupuncture and moxibustion combined with cognitive training and the simple cognitive training for post-stroke mild cognitive impairment (PSMCI). METHODS: Eighty-four patients with PSMCI were randomly divided into an observation group and a control group, with 42 cases in each group (3 cases in the observation group and 2 cases in the control group dropped off). The observation group was treated by Tongdu Xingshen acupuncture and moxibustion combined with cognitive training, acupuncture was given at Baihui (GV 20), Sishencong (EX-HN 1), Shenting (GV 24), etc., and moxibustion was given at Shenting (GV 24) , Baihui (GV 20), Shendao (GV 11), Fengfu (GV 16) and Xinshu (BL 15). The control group was only given cognitive training. All the above treatment was given once a day, 5 times a week, for 4 consecutive weeks. The scores of Montreal cognitive assessment (MoCA), mini-mental state examination (MMSE), activity of daily living (ADL) and stroke-specific quality of life (SS-QOL) were compared between the two groups before treatment, after treatment, 4 weeks and 12 weeks after treatment. RESULTS: After treatment, 4 weeks and 12 weeks after treatment, the MoCA, MMSE and SS-QOL scores of the two groups were all higher than those before treatment (P<0.05), and the ADL scores were lower than those before treatment (P<0.05). In the observation group, the MoCA and MMSE scores were higher than those of the control group after treatment, 4 weeks and 12 weeks after treatment (P<0.05), and the SS-QOL score was higher than that of the control group 12 weeks after treatment (P<0.05). CONCLUSION: Both Tongdu Xingshen acupuncture and moxibustion combined with cognitive training and simple cognitive training can improve cognitive function, daily living ability and quality of life in patients with PSMCI, and the combined therapy is superior to simple cognitive training in improving cognitive function and long-term quality of life in patients with PSMCI.

The safety of COVID-19 vaccines in patients with myasthenia gravis: A scoping review.

Background: COVID-19 vaccines are required for individuals with myasthenia gravis (MG), as these patients are more likely to experience severe pneumonia, myasthenia crises, and higher mortality rate. However, direct data on the safety of COVID-19 vaccines in patients with MG are lacking, which results in hesitation in vaccination. This scoping was conducted to collect and summarize the existing evidence on this issue. Methods: PubMed, Cochrane Library, and Web of Science were searched for studies using inclusion and exclusion criteria. Article titles, authors, study designs, demographics of patients, vaccination information, adverse events (AEs), significant findings, and conclusions of included studies were recorded and summarized. Results: Twenty-nine studies conducted in 16 different countries in 2021 and 2022 were included. Study designs included case report, case series, cohort study, cross-sectional study, survey-based study, chart review, and systemic review. A total of 1347 patients were included. The vaccines used included BNT162b2, mRNA-1273, ChAdOx1 nCoV-19, inactivated vaccines, and recombinant subunit vaccines. Fifteen case studies included 48 patients reported that 23 experienced new-onset, and five patients experienced flare of symptoms. Eleven other types of studies included 1299 patients reported that nine patients experienced new-onset, and 60 participants experienced flare of symptoms. Common AEs included local pain, fatigue, asthenia, cephalalgia, fever, and myalgia. Most patients responded well to treatment without severe sequelae. Evidence gaps include limited strength of study designs, type and dose of vaccines varied, inconsistent window of risk and exacerbation criteria, limited number of participants, and lack of efficacy evaluation. Conclusion: COVID-19 vaccines may cause new-onset or worsening of MG in a small proportion of population. Large-scale, multicenter, prospective, and rigorous studies are required to verify their safety.

Efficacy of acupuncture in refractory irritable bowel syndrome: study protocol for a randomised controlled trial.

INTRODUCTION: Irritable bowel syndrome (IBS) is a common chronic functional gastrointestinal disorder that presents with abdominal pain/discomfort and altered bowel patterns. IBS has multiple potential causes for which conventional medicines have had limited success, resulting in a significant number of patients who do not sensitively respond to pharmacotherapy for a period of 12 months and who develop a continuing symptom profile (described as refractory IBS) and seek help through (non)pharmacological treatments. The aim of this study is to investigate the efficacy and safety of acupuncture therapy for refractory IBS on the basis of conventional treatments. METHODS AND ANALYSIS: A total of 170 eligible patients who meet the Rome IV criteria for refractory IBS will be randomly allocated to receive acupuncture or sham acupuncture. Each patient will receive 12 sessions of acupuncture over 4 weeks and a 4-week follow-up. The primary outcome will be the IBS Symptom Severity Score. Secondary outcomes will include the proportion of participants experiencing adequate relief of global IBS symptoms, the weekly frequency of defecation, the stool properties assessed by the Bristol Grading Scale, the Work and Social Adjustment Scale, the IBS-Quality of Life score, and the Self-Rating Depression Scale and Self-Rating Anxiety Scale anxiety and depression scores. Outcome measures will be collected at baseline, 2 and 4 weeks of the intervention, and 6 and 8 weeks after the intervention. Categorical variables will be compared with Fisher's exact test or the Wilcoxon rank-sum test, and continuous variables will be compared using Student's t-test or the Wilcoxon rank-sum test. ETHICS AND DISSEMINATION: The entire project has been approved by the ethics committees of Beijing University of Chinese Medicine (2020BZYLL0507) and Sichuan Province Regional Institution for Conducting Research on Traditional Chinese Medicine (2020KL-025). The outcomes of the trial will be disseminated through peer-reviewed publications. TRIAL REGISTRATION NUMBER: NCT04276961.

Infrared thermal imaging-based research on the intermediate structures of the lung and large intestine exterior-interior relationship in asthma patients.

OBJECTIVE: By observing body surface temperature variation of the intermediate structures of the Lung (Fei) and Large Intestine (Dachang) exterior-interior relationship in asthmatic patients, to investigate the pathological response on the pathway of channels and to substantiate the objective existence of the intermediary structures. METHODS: The study included 60 subjects meeting the bronchial asthma inclusion criteria (experimental group) and 60 healthy subjects (normal control group). ATIR-M301 infrared thermal imaging device was used for detecting body surface temperature of the subjects and collecting the infrared thermal images. The temperature values of the intermediate structures of Lung and Large Intestine exterior-interior relationship [throat, Quepen, elbow, nose, Lieque (LU 7), Pianli (LI 6)], control areas (0.2 cm lateral to the above structures) and Yintang (EX-HN 3) were measured on the infrared thermal image by infrared imaging system. Then, the above temperature values were compared and analyzed within and between two groups. RESULTS: There were insignificant differences between the temperature on the left and right sides of the intermediate structures (Quepen, elbow, LU 7, LI 6) in normal control group (P>0.05). Except for that of Quepen, there were insignifificant differences between the temperature of the intermediate structures and their corresponding control areas in normal control group (P>0.05). In the experimental group, the temperature on the left and right sides of the intermediate structures (Quepen, elbow, LU 7, LI 6) showed statistically signifificant differences (P<0.05 or P<0.01); the temperature difference between intermediate structure (throat, Quepen, elbow, nose, LI 6) and their respective control areas were also significant (P<0.05 or P<0.01). The temperature of the intermediate structures (throat, Quepen, elbow, LU7, LI 6) between the experimental group and normal control group showed signifificant differences (P<0.05 or P<0.01). CONCLUSIONS: This study is an initial step to validate the objective existence of Lung and Large Intestine exterior-interior relationship intermediate structures, as described in the Chinese classical medical literatures, through the functional imaging angle. The intermediate structures are the pathological reaction areas of the bronchial asthmatic patients.

[Deep needling and shallow needling at three acupoints around ear for subjective tinnitus: a randomized controlled trial].

OBJECTIVE: To compare the effective differences between deep needling and shallow needling at three acupoints around ear for subjective tinnitus. METHODS: Fifty patients with subjective tinnitus were randomized divided into a deep needling group and a shallow needling group, 25 cases in each group. Twenty-two patients in the deep needling group and 20 patients in the shallow needling group were brought into statistic in the end. In the two groups, the three acupoints around ear and distal acupoints were both selected. The acupoints of the affected side such as Yifeng (TE 17), Tinghui (GB 2), Ermen (TE 21), Zhigou (TE 6), Zhongzhu (TE 3) and Hegu (LI 4) were adopted. Yifeng (TE 17), Tinghui (GB 2) and Ermen (TE 21) were acupunctured 30-38 mm in the deep needling group and 15-20 mm in the shallow needling group. The other acupoints were conventionally acupunctured in the two groups. The needles were retained for 30 min,once a day and five times a week for all patients. The treatment was continuously for 4 weeks in the two groups. Tinnitus handicap inventory (THI) scores, tinnitus grades and visual analogue scale (VAS) for tinnitus sound levels were observed before and after treatment, and the effects of the two groups were compared. RESULTS: The total effective rate in the deep needling group was 59.1% (13/22), and it was better than 20.0% (4/20) in the shallow needling group (P < 0.05). In the deep needling, group, the THI score, tinnitus grade and the VAS score were improved than those before treatment (all P < 0.05). In the shallow needling group, the three above indices before and after treatment were not different in statistical significance (all P > 0.05). After treatment, all the three indices in the deep needling group were superior to those in the shallow needling group (all P < 0.05). CONCLUSION: Acupuncture at the three acupoints around ear deeply could apparently improve tinnitus, and reduce tinnitus sound levels for subjective tinnitus. The effect is better than that by shallow needling at the three acupoints.

Clinical trial on the characteristics of zheng classification of pulmonary diseases based on infrared thermal imaging technology.

Zheng classification study based on infrared thermal imaging technology has not been reported before. To detect the relative temperature of viscera and bowels of different syndromes patients with pulmonary disease and to summarize the characteristics of different Zheng classifications, the infrared thermal imaging technology was used in the clinical trial. The results showed that the infrared thermal images characteristics of different Zheng classifications of pulmonary disease were distinctly different. The influence on viscera and bowels was deeper in phlegm-heat obstructing lung syndrome group than in cold-phlegm obstructing lung syndrome group. It is helpful to diagnose Zheng classification and to improve the diagnosis rate by analyzing the infrared thermal images of patients. The application of infrared thermal imaging technology provided objective measures for medical diagnosis and treatment in the field of Zheng studies and provided a new methodology for Zheng classification.

Understanding the viscera-related theory that the lung and large intestine are exterior-interiorly related.

Pairing of the viscera and bowels is an important theory, which provides guidance to traditional Chinese medicine (TCM) clinical practice. Investigating this theory has been the focus of research on the basic theory of TCM. Recently, researchers have performed many studies on the theory that the lung and large intestine are exterior-interiorly related, which is a different point of view to that of previous literature, recent clinical studies and experimental studies, and these recent studies have enforced the theoretical connotation of the statement. However, there are problems in some of these studies including recent clinical studies and experimental studies. In the current article, literature on the viscera-related theory of the lung and large intestine are exterior-interiorly related is reviewed from physiological, pathological, and clinical views, and some opinions on the current research status are discussed.

[Study on the effect of cluster needling of scalp acupuncture on the plasticity protein MAP-2 in rats with focal cerebral infarction].

OBJECTIVE: To investigate the material base and underlying mechanism of the effect of cluster needling of scalp acupuncture on the neuronal plasticity in rats with focal cerebral infarction. METHODS: The model rats with acute cerebral infarction were made by blocking the middle cerebral artery with monofilament. One hundred and thirty two Wistar rats were randomly divided into 4 groups: sham-operation group (A), model group (B), point-to-point scalp acupuncture group (C) and cluster-needling of scalp acupunture group (D). Puncturing from "Baihui (GV 20)" to "Qubin (GB 7)" was used in group C. Cluster needling of scalp acupuncture was used in group D, in which needles were inserted forward and slantingly into "Baihui (GV 20)" and its left and right sides at 4 mm. In both groups, the treatment was carried out with rapid twirling reinforcing-reducing for 1 min then retaining needle for 30 min, once a day, 6 days in one course, for treating 4 courses. There was no treatment for group A and B. The change of neurological function was evaluated with Bederson score, while the expression of microtubule-associated protein 2 (MAP-2) in the ischemic penumbra was examined with immunohistochemistry (streptavidin-peroxidase method). RESULTS: In comparison,with group B, the score of neurological function in group D decreased on 7th day (P<0.05), while the scors in group C and D also decreased on 14th and 28th days (both P<0.05). As compared with group C, the score of neurological function in group D obviously decreased on 28th days (P<0. 05). Comparing with group B, the expression of MAP-2 on the ischemic cortex was significantly increased in group D and C on 7th, 14th and 28th days (all P<0. 05), however, this expression in group D was higher than that in group C on 14th and 28th days (P<0. 05). CONCLUSION: Cluster needling of scalp acupuncture can improve the neurological function of rats with focal cerebral infarction, and increase the expression of MAP-2 in the ischemic penumbra.
