OBJECTIVES: To observe the effect of electroacupuncture (EA) stimulation of "Jiaji"(EX-B2) on motor function, histomorphology, and expression of NOD-like receptor protein 3 (NLRP3) and N-terminal domain of gasdermin D (GSDMD-N) in the spinal cord tissue of rats with spinal cord injury (SCI), so as to explore its mechanism underlying improvement of SCI. METHODS: Forty eight female SD rats were randomly divided into sham surgery (sham), SCI model (model), EA, and NLRP3 agonist (monosodium urate, MSU) combined with Jiaji EA (MSU+EA) groups, with 12 rats in each group which were further divided into 3 d and 7 d subgroups, with 6 rats at each time point. Two EA groups received EA stimulation of EX-B2 with a frequency of 100 Hz, electrical current of 1-2 mA for 30 min, once a day for 3 or 7 days. After 5 min, 6 h, and 24 h of modeling, rats of the MSU+EA group received intraperitoneal injection of MSU (200 µg/kg, 200 µg/mL) . The motor function was evaluated using Basso-Beattie-Bresnahan (BBB) scale, the morphological structure of rat spinal cord tissue was observed by H.E. staining. The expression of pyroptosis related factors NLRP3, cleaved Caspase-1 and GSDMD-N of the spinal cord was observed by using immunohistochemistry and Western blot separately, the expression and localization of Iba-1 and GSDMD-N in the spinal cord tissue were observed using immunofluorescence double staining method. RESULTS: Compared with the sham group, the BBB scores after modeling and on day 3 and 7 were decreased (P<0.05), while the average OD values (immunoactivity) and expression levels of NLRP3, cleaved Caspase-1 and GSDMD-N proteins, and the immunofluorescence intensity of Iba-1/GSDMD-N (co-expression) of the spinal cord tissues on day 3 and 7 were significantly increased in the model group (P<0.05). In comparison with the model group, the BBB scores on day 3 and 7 were obviously increased (P<0.05), while the immunoactivity and expression levels of NLRP3, cleaved Caspase-1 and GSDMD proteins, and the immunofluorescence intensity of Iba-1/GSDMD-N on day 3 and 7 significantly down-regulated in the EA group (P<0.05) but not in the MSU+EA group (P>0.05), suggesting an elimination of the effects of EA after administration of NLRP3 agonist (MSU). H.E. staining showed obvious bleeding area in the spinal cord tissue, loose tissue and inflammatory cell infiltration on day 3 after modeling, and basic absorption of the bleeding, loose tissue, obvious vacuolar changes of the white matter area, loss and contraction of neurons with infiltration of a large number of inflammatory cells, which was milder in the EA group but not in the MSU+EA group. CONCLUSIONS: EA of EX-B2 can improve the motor function of SCI rats, which may be related to its functions in inhibiting pyroptosis of microglia mediated by NLRP3/Caspase-1 signaling pathway.

[Evaluation of the clinical effect of acupuncture in treatment of neck pain in cervical spondylosis based on propensity score matching].

OBJECTIVE: To observe the clinical effect and safety of acupuncture in treatment of neck pain due to cervical spondylosis. METHODS: According to the patients' preference and acceptance for the interventions of neck pain induced by cervical spondylosis, an acupuncture group (221 cases) and a non-acupuncture group (251 cases) were divided. After the control of confounding factors with propensity score matching, 218 cases were included in either acupuncture group or non-acupuncture group. In the acupuncture group, acupuncture was applied to Dazhui (GV 14), Baihui (GV 20), ashi points, bilateral neck-Jiaji (EX-B 2), Fengchi (GB 20), Houxi (SI 3), Shenmai (BL 62), etc. The treatment was given once daily, one course of intervention was composed of 5 treatments and 3 courses were included. In the non-acupuncture group, the oral administration of imrecoxib tablets and cobalt tablets was prescribed for 2 weeks. Before and after treatment, the scores of Northwick Park questionnaire (NPQ) and the simplified McGill pain questionnaire (SF-MPQ) were observed, and the safety was assessed in patients of the two groups. RESULTS: After treatment completion, the scores of NPQ and SF-MPQ were all reduced when compared with those before treatment in each group (P<0.001), and the scores of NPQ and SF-MPQ in the acupuncture group were lower than those of the non-acupuncture group (P<0.001). The incidence of adverse reactions was 6.0% (13/218) in the acupuncture group and was 10.1% (22/218) in the non-acupuncture group, without statistical significance in comparison (P>0.05). CONCLUSION: Acupuncture is effective and safe in the relief of neck pain and the improvement of comprehensive quality of life in the patients with cervical spondylosis.

[Research progress of acupuncture-moxibustion in treatment of spinal cord injury through mediating inflammatory reaction].

Inflammatory reaction after spinal cord injury (SCI) is the main obstacle to the recovery of neural function. In the occurrence and development of SCI, the complex regulatory mechanisms are involved in inflammatory reaction, including the activation of inflammatory cells (e.g.macrophages and microglia), and the release of cytokines (e.g. tumor necrosis factor, interleukin and chemokines). Acupuncture-moxibustion is significantly effective in clinical treatment of SCI, and its mechanism is related to adjusting the function of inflammatory cells after SCI, modulating the expression of cytokines and the activation of NLRP3 inflammatory bodies, as well as the expression of high mobility group protein B1 and calcitonin gene related peptide. This article summarizes the research progress of mechanism of inflammatory reaction after SCI and the effects of acupuncture-moxibustion intervention in recent years so that the new ideas can be provided to clarify the pathogenesis of SCI and the effect of acupuncture-moxibustion intervention.

Anti-inflammatory effect and antihepatoma mechanism of carrimycin.

BACKGROUND: New drugs are urgently needed for the treatment of liver cancer, a feat that could be feasibly accomplished by finding new therapeutic purposes for marketed drugs to save time and costs. As a new class of national anti-infective drugs, carrimycin (CAM) has strong activity against gram-positive bacteria and no cross resistance with similar drugs. Studies have shown that the components of CAM have anticancer effects. AIM: To obtain a deeper understanding of CAM, its distribution, metabolism and anti-inflammatory effects were assessed in the organs of mice, and its mechanism of action against liver cancer was predicted by a network pharmacology method. METHODS: In this paper, the content of isovaleryl spiramycin III was used as an index to assess the distribution and metabolism of CAM and its effect on inflammatory factors in various mouse tissues and organs. Reverse molecular docking technology was utilized to determine the target of CAM, identify each target protein based on disease type, and establish a target protein-disease type network to ascertain the effect of CAM in liver cancer. Then, the key action targets of CAM in liver cancer were screened by a network pharmacology method, and the core targets were verified by molecular docking and visual analyses. RESULTS: The maximum CAM concentration was reached in the liver, kidney, lung and spleen 2.5 h after intragastric administration. In the intestine, the maximum drug concentration was reached 0.5 h after administration. In addition, CAM significantly reduced the interleukin-4 (IL-4) levels in the lung and kidney and especially the liver and spleen; moreover, CAM significantly reduced the IL-1ß levels in the spleen, liver, and kidney and particularly the small intestine and lung. CAM is predicted to regulate related pathways by acting on many targets, such as albumin, estrogen receptor 1, epidermal growth factor receptor and caspase 3, to treat cancer, inflammation and other diseases. CONCLUSION: We determined that CAM inhibited inflammation. We also predicted the complex multitargeted effects of CAM that involve multiple pathways and the diversity of these effects in the treatment of liver cancer, which provides a basis and direction for further clinical research.

[Effect of moxibustion at "oppositely-located points" on neurogenic bladder after spinal cord injury and endoplasmic reticulum stress pathway in rats].

OBJECTIVE: To observe the effect of moxibustion at oppositely-located points "Mingmen" (GV 4) and "Shenque" (CV 8) on the motor function of the hind limbs and bladder function in rats with neurogenic bladder after suprasacral spinal cord injury (SCI), so as to explore the effect of this therapy on bladder tissue apoptosis mediated by endoplasmic reticulum stress pathway. METHODS: Twenty-eight female Wistar rats were randomly divided into a sham-operation group (8 rats) and a model establishment group (20 rats). Using the modified Allen's method, the spinal cord of T10 segment was injured to establish a neurogenic bladder model in the model establishment group. Sixteen rats were modeled successfully and then divided into a model group (8 rats) and a moxibustion group (8 rats). In the moxibustion group, 2 h after consciousness regaining from modeling anesthesia, moxibustion was exerted at "Shenque" (CV 8) and "Mingmen" (GV 4), 2 cones at each acupoint in one intervention. The intervention was administered once every two days and 5-time intervention was required totally. After intervention, Basso, Beattie and Bresnahan locomotor rating scale (BBB) score for the motor function of the hind limbs, and the urodynamics indexes (maximum bladder capacity, urine leakage pressure and bladder compliance) were compared among groups. HE staining method was adopted to observe the morphological changes of bladder tissue. With Western blot method and real-time PCR assay, the protein and mRNA expressions of the endoplasmic reticulum stress-related genes (glucose- regulated protein 78 [GRP78], activating transcription factor 4 [ATF4] and cysteinyl aspartate specific proteinase-12 [Caspase-12]) were determined. RESULTS: The transitional epithelial cells were arranged irregularly, the bladder wall was getting thinner, and the cellular vacuolar degeneration and neutrophil infiltration were found in the model group. Whereas, compared with the model group, in the moxibustion group, the arrangement of transitional epithelial cells was clear and continuous in layers, the cellular vacuolar degeneration was mild and the infiltration presented in a small amount of neutrophil granulocytes. Compared with the sham-operation group, in the model group, the BBB score was reduced (P<0.01), the maximum bladder capacity and bladder compliance were increased (P<0.01), and the protein expression levels of GRP78, ATF4 and Caspase-12, as well as mRNA expressions were all increased (P<0.01). In comparison with the model group, in the moxibustion group, BBB score was increased (P<0.01), the maximum bladder capacity and bladder compliance were decreased (P<0.01), and the protein and mRNA expression levels of GRP78, ATF4 and Caspase-12 were all decreased (P<0.01). CONCLUSION: Moxibustion at the "oppositely-located points" improves the urination function, alleviate urine retention in neurogenic bladder rats after spinal cord injury. The underlying mechanism may be related to the down-regulation of the expressions of GRP78, ATF4 and Caspase-12 in the endoplasmic reticulum stress pathway of the bladder tissues, and thus to alleviate the apoptosis of bladder tissue.

[Research progresses and formulation development of natural anti-mildew agents based on Chinese herbal medicines].

Owing to the intrinsic factors and some extrinsic environmental conditions, many foods, agricultural products and Chinese materia medicas (CMMs), if not handled properly in the processes of growth, harvesting, processing and storage, can be easily contaminated by all kinds of molds to produce mycotoxins of serious toxicity, which will not only affect the quality, safety and effectiveness of CMMs, but also result in potential threatens to human and animal's health and life. Therefore, in recent decades, it has become the focus on how to prevent and control the foods, agricultural products and CMMs from being moldy and producing toxicity for scientific preservation. Many Chinese herbal medicines (CHMs) especially those with high content of volatile oils with strong antifungal activities have been applied for the scientific preservation of foods, agricultural products and CMMs. Based on these situations, natural anti-mildew agents have been further developed and made into some useful dosage forms, such as tablets, aerosol, liposomes and inclusion, which will not only greatly expand the application scope of CHMs to make the use of anti-mildew agents more convenient, but also achieve the sustained or controlled release of the antifungal effect for scientific preservation of foods, agricultural products and CMMs.

Effects of electroacupuncture therapy for Bell's palsy from acute stage: study protocol for a randomized controlled trial.

BACKGROUND: Although many patients with facial paralysis have obtained benefits or completely recovered after acupuncture or electroacupuncture therapy, it is still difficult to list intuitive evidence besides evaluation using neurological function scales and a few electrophysiologic data. Hence, the aim of this study is to use more intuitive and reliable detection techniques such as facial nerve magnetic resonance imaging (MRI), nerve electromyography, and F waves to observe changes in the anatomic morphology of facial nerves and nerve conduction before and after applying acupuncture or electroacupuncture, and to verify their effectiveness by combining neurological function scales. METHODS/DESIGN: A total of 132 patients with Bell's palsy (grades III and IV in the House-Brackmann [HB] Facial Nerve Grading System) will be randomly divided into electroacupuncture, manual acupuncture, non-acupuncture, and medicine control groups. All the patients will be given electroacupuncture treatment after the acute period, except for patients in the medicine control group. The acupuncture or electroacupuncture treatments will be performed every 2 days until the patients recover or withdraw from the study. The primary outcome is analysis based on facial nerve functional scales (HB scale and Sunnybrook facial grading system), and the secondary outcome is analysis based on MRI, nerve electromyography and F-wave detection. All the patients will undergo MRI within 3 days after Bell's palsy onset for observation of the signal intensity and facial nerve swelling of the unaffected and affected sides. They will also undergo facial nerve electromyography and F-wave detection within 1 week after onset of Bell's palsy. Nerve function will be evaluated using the HB scale and Sunnybrook facial grading system at each hospital visit for treatment until the end of the study. The MRI, nerve electromyography, and F-wave detection will be performed again at 1 month after the onset of Bell's palsy.

[Study on medical pattern of traditional Chinese medicine and western medicine diagnosis and treatment of hypertension patients in 30 034 cases in real world].

Select patients diagnosed of hypertension in the first place in 16 hospitals and the patients were described by association rules analysis and distribution for the analysis in the study,in order to understand the information of diagnosis and treatment in hypertension patients in real world. The information include age, gender, admission condition, inpatient department, hospitalization expenses, western medicine comorbidities, the traditional Chinese medicine (TCM) syndrome and the medicine. The average age of patients was 64 years in the study. The proportion of men to women about 1. 10: 1. Admission condition is critical for about 10.12% of the total and more concentrated in the cardiovascular department. Hospital stay ranged from 8 to 14 d. Inpatients with medical insurance is 62.93%. Total hospitalization cost distribution most is the 5 000-10 000 RMB. Hypertension complicated with coronary heart disease, blood lipoprotein disorder disease; phlegm and blood stasis and Yin deficiency of liver and kidney are the most in TCM syndrome type. Promoting blood circulation and removing blood stasis is the major in Chinese medicine treatment. Western medicine treatment basically conforms to the guidelines. The most antihypertensive drugs is calcium antagonistst, accounting for about 81.2% of the total number. Class ACEI, class ARB, beta blockers, diuretics class are accounted for 43.0%, 43.4%, 42.4%, 42.4%, fixed compound is only 2 393, accounting for about 8%. the total frequency of five classes of antihypertensive drugs is 78 206 times. The principal conclusions of this analysis are as follows: the elderly people is the most in hypertension, more men than women; medical insurance is the majority type in hospitalization cost; nearly half of the population is combined with coronary heart disease; phlegm and blood stasis and yin deficiency of liver and kidney are the most in TCM syndrome type; western medicine treatment basically conforms to the guidelines. Combination therapy is more, less fixed compound preparation in western medicine. Chinese medicine is mainly to promoting blood circulation. Suggesting that the clinical treatment in strict blood pressure and at the same time, pay attention to combination therapy and the use of fixed compound preparation,it's useful to control the blood pressure better. Combined with traditional Chinese medicine and resolving phlegm and removing blood stasis, reduce the target organ damage, reduce complications, the prevention and control work of hypertension in China still faces enormous challenges at present. The result provides reference information for clinical medicine and medical research.

[Meridians and acupoints with opposite locations].

A new combination of acupoints with opposite locations in clinic was proposed according to the running course of meridians and the relation between meridians and acupoints in order to enrich the theory of acupuncture-moxibustion and enhance the therapeutic effect. Points with opposite location refers to bigeminal acupoints locates at the medial and lateral aspects of the limbs or at the anterior or posterior aspects of the trunk, such as Neiguan (PC 6) and Waiguan (TE 5), Quchi (LI 11) and Shaohai (HT 3) as well as Yinlingquan (SP 9) and Yanglingquan (GB 34). Those pairs of points locate respectively at yin meridians and yang meridians with opposite locations or at meridians interiorly and exteriorly related with each other. The application of the combination and the therapeutic effects can be found both in ancient and modern time. Its theoretical foundation rests with the theory of yin-yang and meridians, which takes yin-yang as the core. The characteristics of the combination are as the follows: firstly, it can regulate yin and yang, qi and blood at the same time. Secondly, yin and yang can influence each other; it is easy to locate the other point when one of the pair is located, and it is easy to manipulate by needling two points oppositely at the same time or doing through-and-through needling. The technique is also known with its selection of less point but better effect.

[Study on teaching techniques of meridians and acupoints].

According to the law of circulation of meridians and the locations of acupoints, the opposite acupoints were proposed. It facilitates comprehension of the routes of meridians and the locations of acupoints. Application of opposite needling or penetrative needling, it is easy to practice and the effectiveness is significant. Promoting this concept into acupuncture training, can expand out from acupoint to meridian, from one meridian to other meridians, it will generate good rewards.
