Effect of Acupoint Catgut Embedding for Middle-Aged Obesity: A Multicentre, Randomised, Sham-Controlled Trial.

Objectives: This study aimed to examine the efficacy and safety of acupoint catgut embedding (ACE) for obesity over a 16-week treatment period using sham stimulation as the control. Methods: A multicenter, randomised, parallel, sham-controlled trial was conducted from February 10, 2017, to May 15, 2018. Men with waistlines ≥85 cm and women with ≥80 cm at three sites were randomised to receive eight sessions (over 16 weeks) of ACE (n = 108) or sham ACE (n = 108) with skin penetration at sham acupoints. The catgut was embedded once every two weeks using two alternating sets of acupoints. The follow-up lasted for an additional 24 weeks. The primary outcome was the percentage waistline reduction from baseline to week 16. Results: We included 216 individuals in the intention-to-treat analysis. At 16 weeks, the rate of waistline reduction was 8.80% (95% confidence interval (CI), 7.93% to 9.66%) in the ACE group and 4.09% (95% CI, 3.18% to 5.00%) in the sham control group, with a between-group difference of 4.71% (95% CI, 3.47% to 5.95%; P < 0.0001). This difference persisted throughout the entire follow-up period (between-group difference after 24-week additional weeks, 4.94% (95% CI, 3.58% to 6.30%); P < 0.001). The subgroup analyses of waistline by sex (male/female) revealed treatment effects of 1.93 (95% CI, -0.37 to 4.23, P = 0.1) in the male group and 3.19 (95% CI, 1.99 to 4.39, P < 0.001) in the female group. The adverse event analysis suggested that ACE and laboratory tests confirmed the safety of ACE. Discussion. ACE for 16 weeks could decrease the waistline and weight and was safe for the treatment of obesity. Further research is needed to evaluate the long-term efficacy and sex differences. This trial is registered with NCT02936973.

Comparative effectiveness of herb-partitioned moxibustion plus lifestyle modification treatment for patients with simple obesity: A study protocol for a randomized controlled trial.

INTRODUCTION: Obesity is a global public health issue, which results in many health complications. Moxibustion may serve as an alternative management for simple obesity, where pharmacological therapy is always difficult to be accepted by the majority of obese patients based on its safety. However, the effects of herb-partitioned moxibustion as obesity intervention have not been confirmed. This study is designed as a single-blinded, 3-dummy randomized controlled trial to evaluate the efficacy and safety of herb-partitioned moxibustion plus lifestyle modification treatment in patients with simple obesity. METHODS AND ANALYSIS: This study will be a randomized, controlled trial conducted from April, 2019 to April, 2021 that includes 108 participants who have simple obesity and meet the eligibility criteria. The participants will be randomly divided into 3 treatment groups: heat application group, medicated plaster group, or herb-partitioned moxibustion group. Each treatment will last 4 weeks. The primary outcomes will be the clinical effectiveness. The secondary outcome measures include participants' obesity-related indicators, the IWQOL-Lite scale, and the syndrome score of Traditional Chinese Medicine. Adverse events will be recorded during the intervention period. ETHICS AND DISSEMINATION: Ethical approval of this study was granted by the Ethics Committee of Hubei Provincial Hospital of Traditional Chinese Medicine on 15 November 2018 (Ethics Reference No: HBZY2018-C24-01). Written informed consents will be provided by all participants before they were enrolled in this study. TRIAL REGISTRATION NUMBER: NCT04606680.

Clinical effect of catgut implantation at acupoints for the treatment of simple obesity: A multicentre randomized controlled trial.

BACKGROUND: Catgut implantation at acupoints (CIA) is a subtype of acupuncture that has been widely used to treat simple obesity, but evidence for its effectiveness remains scarce. The aim of this study is to evaluate the efficacy and safety of treating simple obesity with CIA. OBJECTIVE: This clinical trial aims to evaluate the effectiveness and safety of CIA used for treatment of simple obesity. METHODS: This is a multicentre, randomized, parallel, sham-controlled clinical trial. A total of 216 patients with simple obesity will be recruited. They will be randomly assigned in a 1:1 ratio to either the CIA group or the sham control group. All treatments will be given once every 2 weeks. The primary outcome measure is the rate of waistline reduction. Secondary outcome measures are the rates of reduction of body measurements, including weight, body mass index (BMI), hipline, waist-hip-ratio (WHR) and body fat percentage (BFP), the changes in scores on scales, including the Impact of Weight on Quality of Life Questionnaire (IWQOL-Lite), Short Form 36 (SF-36), the Hospital Anxiety and Depression Scale (HAD) and the Self-Esteem Scale (SES), Outcomes will be evaluated at baseline and at weeks 4, 8, 12, 16, 28, and 40, respectively. All adverse events that occur during this study will be recorded. If any participant withdraws from the trial, an intention-to-treat analysis (ITT) will be performed. CONCLUSION: This is a randomized, sham-controlled trial of CIA treatment for simple obesity. The results of this trial will provide more evidence on whether CIA is efficacious and safe for treating obesity. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02936973.

[Moxibustion therapy in prevention and treatment of coronavirus disease 2019 (COVID-19): construction and application of non-contact diagnosis and treatment mode].

OBJECTIVE: To establish and promote the non-contact doctor-patient interactive diagnosis and treatment mode based on mobile internet for the treatment of coronavirus disease 2019 (COVID-19) with moxibustion therapy, and to observe the feasibility and effectiveness of the model in the pandemic. METHODS: A total of 43 first-line medical staff and 149 suspected and confirmed cases with COVID-19 [18 cases in medical observation period, 17 cases of mild type (cold dampness and stagnation in the lung), 24 cases of ordinary type (cold-dampness accumulated in the lung) and 90 cases in recovery period (qi deficiency of spleen and lung)] were included. A non-contact doctor-patient interactive diagnosis and treatment platform was established for the treatment of COVID-19 with indirect moxibustion plaster based on mobile internet. By the platform, the patients were instructed to use indirect moxibustion plaster in treatment. For the first-line medical staff and patients in the medical observation period, Zusanli (ST 36), Qihai (CV 6) and Zhongwan (CV 12) were selected. For the mild cases (cold dampness and stagnation in the lung) and the cases of ordinary type (cold-dampness accumulated in the lung), Hegu (LI 4), Taichong (LR 3), Zusanli (ST 36) and Guanyuan (CV 4) were selected. In the recovery period (qi deficiency of spleen and lung), Dazhui (GV 14), Feishu (BL 13), Geshu (BL 17), Zusanli (ST 36) and Kongzui (LU 6) were used. The treatment was given once daily for 40 min each time. The intervention lasted for 10 days. After intervention, the infection rate and the improvement in the symptoms and psychological status of COVID-19 were observed in clinical first-line medical staff and COVID-19 patients. RESULTS: In 10 days of intervention with indirect moxibustion plaster, there was "zero" infection among medical staff. Of 43 first-line physicians and nurses, 33 cases had some physical symptoms and psychological discomforts, mainly as low back pain, poor sleep and anxiety. After treatment, regarding the improvements in the symptoms and psychological discomforts, the effective rate was 78.8% (26/33) and the curative rate was 36.4% (12/33). Regarding the improvements in psychological discomforts, the effective rate was 58.3% (14/24) and the curative rate was 37.5 (9/24). Of 149 patients, 133 cases had the symptoms and psychological discomforts. After treatment, regarding the improvements in the symptoms and psychological discomforts, the effective rate was 81.2% (108/133) and the curative rate was 34.6% (46/133). Regarding the improvements in psychological discomforts, the effective rate was 76.5% (52/68) and the curative rate was 57.4 % (39/68). CONCLUSION: It is feasible to apply the indirect moxibustion plaster technique based on mobile internet to the treatment COVID-19. This mode not only relieves the symptoms such as cough and fatigue, improves psychological state, but also possibly prevents the first-line medical staff from COVID-19.

Moxibustion combined with characteristic lifestyle intervention of Traditional Chinese Medicine in the treatment of abdominal obesity: A study protocol for a randomized controlled trial.

BACKGROUND: Abdominal obesity occurs when excessive visceral and subcutaneous fat is built up around the abdomen and stomach, which negatively impacts human health. Moxibustion, arose from Traditional Chinese Medicine (TCM), has been widely applied in the treatment of abdominal obesity. Several studies have shown the positive effects of moxibustion in prevention and treatment of endocrine issues and excess body weight. In this context, our study aims to examine the safety and efficacy of the combination of moxibustion and characteristic lifestyle intervention of TCM in the treatment of abdominal obesity. METHODS/DESIGN: This study will be a multicenter, randomized, controlled trial conducted from September 2020 to January 2022 that includes 150 participants who have abdominal obesity and meet the eligibility criteria. The participants will be randomly divided into 3 groups in a 2:2:1 allocation ratio. The intervention group will receive moxibustion combined with characteristic lifestyle intervention of TCM; the other group will receive moxibustion combined with lifestyle intervention; the control group will receive lifestyle intervention only. Eight-week moxibustion sessions will be provided to participants assigned to the 2 intervention groups. The characteristic lifestyle intervention of TCM will also last 8 weeks, whereas the lifestyle intervention will last 12 weeks including 8-week treatment period, 4-week follow-up period. The primary outcome is the waist circumference measured by a tape measure. The secondary outcomes include obesity-related indicators, serum biochemical indexs, blood pressure, conversion score of physical symptoms, and measurement of the scale. Adverse events will be recorded during the treatment and follow-up period. DISCUSSION: The results are expected to provide clinical evidence for the application of the combination of moxibustion and characteristic lifestyle intervention of TCM in patients with abdominal obesity.

[Analysis on the theory and clinical ideas of acupuncture and moxibustion for the prevention and treatment of coronavirus disease 2019].

Acupuncture and moxibustion has a wealth of experience in the prevention and control of epidemic disease since ancient times, which was used for all kinds of acute infectious diseases in modern times and its efficacy has been clearly and reliably reported. This article proposes the theoretical feasibility and reliability of acupuncture and moxibustion interventional prevention and treatment by discussing the recognition of coronavirus disease 2019 (COVID-19) from the perspective of acupuncture and moxibustion. The unique "acupuncture and moxibustion program" for COVID-19 is presented including treatment in different stages, selecting acupoints by distinguishing meridians, applying needle technique by various methods. The article also proposes a new understanding of acupuncture and moxibustion at related acupoints on the surface of the body that can directly affect the "moyuan" to treat the disease.

Effect and Safety of Hydroxysafflor Yellow A for Injection in Patients with Acute Ischemic Stroke of Blood Stasis Syndrome: A Phase II, Multicenter, Randomized, Double-Blind, Multiple-Dose, Active-Controlled Clinical Trial.

OBJECTIVE: To assess the effect and safety of Hydroxysafflor Yellow A for Injection (HSYAI) in treating patients with acute ischemic stroke (AIS) and blood stasis syndrome (BSS). METHODS: A multicenter, randomized, double-blind, multiple-dose, active-controlled phase II trial was conducted at 9 centers in China from July 2013 to September 2015. Patients with moderate or severe AIS and BSS were randomly assigned to low-, medium-, high-dose HSYAI groups (25, 50 and 70 mg/d HSYAI by intravenous infusion, respectively), and a control group (Dengzhan Xixin Injection (, DZXXI) 30 mL/d by intravenous infusion), for 14 consecutive days. The primary outcome was the Modified Rankin Scale (mRS) score ⩽1 at days 90 after treatment. The secondary outcomes included the National Institute of Health Stroke Scale (NIHSS) score ⩽1, Barthel Index (BI) score ⩾95, and BSS score reduced ⩾30% from baseline at days 14, 30, 60, and 90 after treatment. The safety outcomes included any adverse events during 90 days after treatment. RESULTS: Of the 266 patients included in the effectiveness analysis, 66, 67, 65 and 68 cases were in the low-, medium-, and high-dose HSYAI and control groups, respectively. The proportions of patients in the medium- and high-dose HSYAI groups with mRS score ⩽1 at days 90 after treatment were significantly larger than the control group (P<0.05). The incidences of favorable outcomes of NIHSS and BI at days 90 after treatment as well as satisfactory improvement of BSS at days 30 and 60 after treatment in the medium- and high-dose HSYAI groups were all significantly higher than the control group (P<0.05). No significant difference was reported among the 4 groups in any specific adverse events (P>0.05). CONCLUSIONS: HSYAI was safe and well-tolerated at all doses for treating AIS patients with BSS. The medium (50 mg/d) or high dose (75 mg/d) might be the optimal dose for a phase III trial. (Registration No. ChiCTR-2000029608).

Kalshiolin A, new lignan from Kalimeris shimadai.

The Asian plant Kalimeris shimadai has been used as food and ethnologic medicine for over a thousand years. In this study, we isolated and identified one new lignan, kalshiolin A (1), and 12 known lignans (2-13). The structures were characterized by the comprehensive analyses of spectroscopic data (HR-ESI-MS, IR, 1D, and 2D-NMR) and the absolute configuration of 1 was determined from ECD calculations. The new compound 1 was also screened for cytotoxic activity but did not show significant potency (IC50 35.9-43.3 µM) against A549, MDA-MB-231, MCF7, KB, and KB-VIN cell lines.

Effect of Electroacupuncture on Neurological Deficit and Activity of Clock and Bmal1 in Cerebral Ischemic Rats.

Acute focal cerebral ischemic stroke (IS) is a leading cause of morbidity and mortality worldwide. Acupuncture is an emerging alternative therapy that has been beneficial to acute brain ischemia. However, the underlying protective mechanism of its neuroprotective effect remains unclear. Human original circadian rhythm will be lost after IS, which seriously affects the quality of life and functional recovery of stroke patients. We hypothesize that acupuncture treats IS by regulating the balance of Clock and Bmal1. This study aims to explore the effect of acupuncture at acupoints GV20 and BL23 on neuroprotection and anti-apoptosis in middle cerebral artery occlusion (MCAO) rats and expression of apoptosis and circadian rhythm related proteins. Male Sprague-Dawley (SD) rats were randomly divided into five groups: normal group (Normal), sham model group (Sham MCAO), MCAO model group (MCAO), sham electroacupuncture group (Sham EA) and electroacupuncture group (EA). The MCAO model was prepared by electrocoagulation. The first acupuncture treatment was performed within 2 h after surgery, and then acupuncture therapy was performed on 1st day, 2nd day and 3rd day respectively. After their neurological examination at 72 h of ischemia, the rats from each group were sacrificed. Triphenyltetrazolium chloride (TTC) staining was used to evaluate the brain infarct size. Ultrastructural observation on cerebral ischemic cortex and serum inflammatory cytokines were evaluated. TUNEL staining was used to detect cell apoptosis of brain tissue. The expression levels of proteins Bax, bcl-2, caspase-3, Clock and Bmal1 in the cerebral ischemic region were detected by immunofluorescence staining. Here, we presented evidence that EA at GV20 and BL23 could significantly improve the neurological deficit score and infarct size, and alleviate the cell apoptosis of brain tissue. Moreover, acupuncture treatment upregulated the anti-apoptotic Bcl-2/Bax ratio and reversed the upregulation of caspase-3 following 72-h cerebral ischemia. In addition, the expression levels of circadian proteins Clock and Bmal1 were upregulated in EA group while compared with MCAO group. Our study demonstrated that acupuncture exerted neuroprotective effect against neuronal apoptosis after stroke and the mechanism might be related with regulation of circadian rhythm proteins Clock and Bmal1.

The hepatoprotective activities of Kalimeris indica ethanol extract against liver injury in vivo.

Kalimeris indica (L.) Sch. Bip. is a traditional Chinese medicine (TCM) and a portion of food used for cooking in China. It has been demonstrated that an ethanol extract of K. indica has an anti-inflammatory effect by inhibition of nitric oxide (NO) production on murine macrophage RAW264.7 cells after lipopolysaccharide (LPS) induction. In this study, the hepatoprotective effects of the total phenolics of K. indica (TPK), the total triterpenes of K. indica (TTK), and the total flavones of K. indica (TFK) from ethanol extracts of K. indica were evaluated in Bacille Calmette-Guerin (BCG)/LPS-induced liver injury in vivo. The treatments of TPK, TTK, and TFK improved liver injury in mice. Additionally, all treatments significantly not only reduced the hepatic malondialdehyde (MDA) content and hepatic total nitric oxide synthase (tNOS) but also induced the hepatic superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activity. The treatments of TPK and TTK significantly reduced the hepatic inducible nitric oxide synthase (iNOS). The treatments of TPK, TTK, and TFK reduced the serum total bilirubin (T-Bil), and only TFK treatment reduced the serum alanine aminotransferase (ALT). Our results suggest that TPK, TTK, and TFK from ethanol extracts of K. indica might play an essential protective role against BCG/LPS-induced liver injury in vivo.

[Effect of electroacupuncture combined with treadmill exercise on body weight and expression of PGC-1α， Irisin and AMPK in skeletal muscle of diet-induced obesity rats].

OBJECTIVE: To investigate the effect of electroacupuncture (EA) plus treadmill exercise on the expression of peroxisome proliferator activated receptor γ coactivator 1α(PGC-1α), Irisin, AMP-activated protein kinase (AMPK) in skeletal muscle of diet-induced obesity (DIO) rats, so as to explore its mechanism underlying body reduction promotion. METHODS: Forty-two male SD rats were divided into normal diet (control, n＝10), high fat diet (model), EA, treadmill exercise and EA plus treadmill exercise (combination) groups (n＝8 in each of the latter 4 groups). The obesity model was established by feeding the rats with high fat diet. EA (2 Hz/15 Hz, 1 mA) was applied to bilateral "Zusanli" (ST36) and "Tianshu" (ST25) for 30 min, 5 times per week for a total of 8 weeks. Rats of the treadmill exercise group were forced to perform exercise on a treadmill (16 m/min) for 30 min, 5 times per week for a total of 8 weeks. Rats in the combination group received the above-mentioned two methods. During the treatment, rats in the control group were fed with normal fodder, rats in other groups were fed with high fat fodder, and their body weight was measured once a week. The expression levels of PGC-1α， fibronectin type Ⅲ domain containing 5 (FNDC5), AMPK mRNA and protein of skeletal muscle were measured by quantitative real-time PCR and Western blot，respectively. RESULTS: After modeling, the body weight was significantly increased (P<0.05), and the expression levels of PGC-1α and FNDC5 mRNA and protein, AMPK mRNA and phosphorylated AMPK (p-AMPK) protein in the skeletal muscle were considerably decreased in the model group relevant to the control group (P<0.05). Following the treatment, the body weight was significantly down-regulated, while the expression levels of PGC-1α and FNDC5 mRNAs and proteins, AMPK mRNA and p-AMPK protein were obviously up-regulated in the EA, treadmill exercise and combination groups relevant to the model group (P<0.05). The therapeutic effect of EA plus treadmill exercise was significantly superior to those of both simple EA and simple treadmill exercise in down-regulating the body weight, as well as in up-regulating the expression of PGC-1α and FNDC5 mRNAs and proteins, AMPK mRNA, and p-AMPK protein (P<0.05). CONCLUSION: Both EA and treadmill exercise can significantly increase the expression of PGC-1α， FNDC5 and p-AMPK in skeletal muscle of DIO rats, suggesting their efficacy in restoring fatty acid oxidation in skeletal muscle cells and improving mitochondrial function, which may contribute to their function in body reduction. The therapeutic effect of EA plus treadmill exercise is better than that of simple EA and simple treadmill exercise.

Mechanisms of Acupuncture Therapy for Simple Obesity: An Evidence-Based Review of Clinical and Animal Studies on Simple Obesity.

Simple obesity is a worldwide epidemic associated with rapidly growing morbidity and mortality which imposes an enormous burden on individual and public health. As a part of Traditional Chinese Medicine (TCM), acupuncture has shown the positive efficacy in the management of simple obesity. In this article, we comprehensively review the clinical and animal studies that demonstrated the potential mechanisms of acupuncture treatment for simple obesity. Clinical studies suggested that acupuncture regulates endocrine system, promotes digestion, attenuates oxidative stress, and modulates relevant molecules of metabolism in patients of simple obesity. Evidence from laboratory indicated that acupuncture regulates lipid metabolism, modulates inflammatory responses, and promotes white adipose tissue browning. Acupuncture also suppresses appetite through regulating appetite regulatory hormones and the downstream signaling pathway. The evidence from clinical and animal studies indicates that acupuncture induces multifaceted regulation through complex mechanisms and moreover a single factor may not be enough to explain the beneficial effects against simple obesity.

[Comparison of therapeutic effects of electroacupuncture and acupoint catgut embedding in redu-cing serum leptin and insulin levels in simple obesity patients].

OBJECTIVE: To observe the therapeutic effect of electroacupuncture (EA) and acupoint catgut embedding in the treatment of simple obesity. METHODS: Simple obesity patients were randomized into EA group (7 men and 36 women, 21－42 years in age) and catgut embedding group (4 men and 37 women, 22－41 years in age). EA (4 Hz/20 Hz, a tolerable strength) was applied to main acupoints Zhongwan (CV12), bilateral Tianshu (ST25), Daheng (SP15), Daimai (GB26), Shuidao (ST28), Zhigou (TE6), Yinlingquan (SP9), Zusanli (ST36), Fenglong (ST40), and Sanyinjiao (SP6), and some auxiliary acupoints for 30 min, once every other day for 30 times. Subcutaneous catgut-embedment was performed in the same acupoints. Nine to 11 acupoints were used every time, once every 10 days for 6 times. Before and after the treatment, fasting serum leptin and insulin (INS) contents were detected by radioimmunoassay, and the correlation between the leptin, INS and the body mass index (BMI) was analyzed, respectively. RESULTS: Following the treatment, the serum leptin and INS concentrations and BMI in both groups were significantly decreased in comparison with those of their own pre-treatment (P<0.01). No significant differences were found between the two groups in the levels of serum leptin and INS after the treatment (P>0.05). There were positive correlations between the decreased BMI and serum leptin/INS contents in both EA and catgut embedding groups (P<0.01). CONCLUSION: Both catgut embedding and EA interventions have a positive effect in reducing body weight of simple obesity patients, which may be related to its effects in down-regulating serum leptin and INS levels and in correcting leptin resistance and insulin resistance.

[Electroacupuncture Reduces Body Fat by Down-regulating IL-6 and Vimentin in Abdominal White Adipose Tissue of Diet-induced Obesity Rats].

OBJECTIVE: To investigate the effect of electroacupuncture (EA) on IL-6 and vimentin protein expression in white adipose tissue (WAT) of diet-induced obesity (DIO) rats, so as to reveal its mechanism underlying losing weight. METHODS: Thirty-four Wistar rats were randomly divided into normal (control, n＝10), model, sham-EA and EA groups (n＝8 in each of the latter 3 groups). The obesity model was established by feeding the rats with high fat diet. EA (2 Hz/15 Hz, 1 mA) was applied to bilate-ral "Zusanli "(ST 36) and "Tianshu "(ST 25) for 30 min, 5 times per week for a total of 8 weeks. For sham-EA group, two sham points (about 5 mm lateral to ST 36 and to ST 25) were only punctured with filiform needles but without electrical stimulation. Du-ring EA treatment, all rats were fed with normal fodder, and their body weight were measured once a week. Histopathologic changes (diameters of adipose cells) of abdominal WAT were observed under microscope after sectioning and H．E. staining, and the expression levels of IL-6 and vimentin in the WAT were detected by Western blot. RESULTS: Compared with the control group, the body weight, diameter of fat cells and the expression levels of IL-6 and vimentin in the WAT were significantly increased in the model group (P<0.05). Following EA, the body weight, diameter of fat cells and the expression levels of IL-6 and vimentin proteins were considerably down-regulated in the EA group (P<0.05), rather than in the sham-EA group relevant to the model group (P>0.05)．. CONCLUSION: EA intervention can effectively down-regulate the expression of IL-6 and vimentin in WAT of DIO rats, which may contribute to its action in reducing body fat by relieving chronic inflammation.

[Electroacupuncture Relieves Obesity by Up-regulating PGC-1 α/UCP-1 Signaling in White Adipose Tissue in Diet-induced Obesity Rats].

OBJECTIVE: To observe the effect of electroacupuncture (EA) on the activities of peroxisome proliferator-activated receptor gamma coactivator-1 alpha/uncoupling protein-1 (PGC-1 α/UCP-1) signaling pathway in white adipose tissue(WAT)of diet-induced obesity (DIO) rats, so as to reveal its underlying mechanism in body weight loss. METHODS: Thirty-four male Wistar rats were randomly divided into normal diet (control, n＝10), high fat diet (model), sham EA-acupoint and EA groups (n＝8 in each of the latter 3 groups). The obesity model was established by feeding the rats with high fat diet containing lard oil, sugar, albumen powder, cholesterol, salt and sodium cholate for 12 weeks. EA (2 Hz/15 Hz, 1 mA) was applied to bilateral "Zusanli" (ST 36) and "Tianshu" (ST 25) or sham acupoints (about 5 mm beside ST 36 and ST 25) for 30 min, once daily, 5 times per week for a total of 8 weeks. During the treatment, all rats were fed with normal diet, and their body weight and length were measured once a week for calculating the Lee's index. The contents of serum total cholesterol (TC) and triglyceride (TG) were measured by using biochemical methods. The immunoactivity of PGC-1 α and UCP-1 in the abdominal WAT was detected by immunohistochemistry. RESULTS: After modeling, the Lee's index, serum TC and TG contents were significantly increased, and the levels of serum HDL-C, and PGC-1 α and UCP-1 immunoactivity in WAT considerably decreased in the model group relevant to the control group (P<0.05). Following the treatment, the Lee's index, TC and TG contents were significantly down-regulated while HDL-C and PGC-1 α and UCP-1 immunoactivity were obviously up-regulated in the EA-acupoint group relevant to the model group (P<0.05). CONCLUSION: EA can effectively reduce the body weight and adipose content in obesity rats, which may be closely related to its effect in up-regulating PGC-1 α/UCP-1 signaling in WAT, suggesting an efficacy of EA in promoting the browning of WAT.

[Regularity of Acupoint Selection for Simple Obesity Treated by Acupoint Catgut Embedding Based on Complex Network Technology].

OBJECTIVE: To analyze the core acupoints and acupoint combinations of catgut embedding for simple obesity based on the complex network technology. METHODS: Articles about acupoint catgut embedding for simple obesity were collec-ted from databases of PubMed, CNKI, Wanfang and VIP from 1980 to 2016 by using keywords "simple obesity" "obesity" "acupoint embedding" "acupuncture" and "traditional Chinese medicine"， followed by constructing a database of acupoint prescription. Acupoint node (one node means an acupoint) weighted complex network was constructed by using complex network technique, followed by conducting centrality analysis and clustering analysis about the nodes using Matlab 2014, a software for revealing the core acupoint node and compatibility relations. At last, theresults (complex network diagram) were displayed using software Gephi 0.9.1. RESULTS: A total of 238 articles (all in Chinese) including 278 acupoints (of which 115 are meridian acupoints) were collected. The top 15 core acupoints are Tianshu (ST 25), Zusanli (ST 36), Zhongwan (CV 12), Fenglong (ST 40), San-yinjiao (SP 6), Quchi (LI 11), Yinlingquan (SP 9), Guanyuan (CV 4), Pishu (BL 20), Qihai (CV 6), Shenshu (BL 23), Shangjuxu (ST 37), Daheng (SP 15), Shuifen (CV 9), and Ganshu (BL 18), mainly distributing in the abdomen, lower limbs and back. Those acupoints with the highest core degree are attributed to the Stomach Meridian, Conception Vessel, Bladder Meri-dian, Spleen Meridian and Large Intestine Meridian. Regarding the compatibility of these acupoints, ST 25 and CV 12 have the highe-st correlation frequency, followed by ST 25 and ST 36, and ST 40 and ST 25, indicating the principle of different combinations being regional acupoints and meridian acupoints. CONCLUSION: In the treatment of simple obesity with catgut embedding, top 15 core acupoints as ST 25, ST 36, CV 12, ST 40, etc, and acupoint recipes as ST 25 and CV 12, ST 25 and ST 36, ST 40 and ST 25 are most frequently used in clinical practice.

The WT1/MVP-Mediated Stabilization on mTOR/AKT Axis Enhances the Effects of Cisplatin in Non-small Cell Lung Cancer by a Reformulated Yu Ping Feng San Herbal Preparation.

Chemo-resistance is an obstacle in therapy of lung cancer. Alternative therapy of using herbal medicine has been proposed to resolve this obstacle. Yu Ping Feng San (YPFS), a common Chinese herbal medicinal mixture, has been reported to show anti-drug resistance on cisplatin (DDP), a common lung cancer drug. To optimize the anti-cancer function of YPFS, different Chinese herbal extracts having known function to overcome lung cancer were screened in combining with YPFS, as to increase the efficacy of DDP in drug resistance lung cancer cell, A549/DDP. Amongst these herbal extracts, Ginkgo Folium exhibited the most promoting sensitized effect. This revised herbal formula, named as YPFS+GF, promoted the DDP-induced toxicity by over 2-fold as compared to that of YPFS alone; this potentiation was confirmed by inducing cell apoptosis. The anti-drug resistance of YPFS, triggered by an increase of intracellular concentration of DDP, was accompanied by an increased expression and activity of WT1, which consequently decreased the transcript level of MVP. In addition, the MVP-mediated downstream effector mTOR2/AKT was disrupted after application of YPFS+GF in DDP-treated A549/DDP cell: this disruption was characterized by the decline of mTORC2 components, e.g., Rictor, p-mTOR, as well as the phosphorylation level of its downstream protein AKT. The disruption on mTORC2/AKT could be reversed by mTORC2 inducer insulin and promoted by mTORC2 inhibitor PP242. Thus, the anti-drug resistance of YPFS+GF in DDP-treated lung cancer cells might be mediated by the down regulation of WT1/MVP axis, as well as the downstream anti-apoptotic pathway of mTORC2/AKT signaling. Herbal medicine is one of the main adjuvant therapies in non-small cell lung cancer, and this novel herbal formula supports the prescription of traditional Chinese medicine in cancer treatment.

Limonoids and triterpenoid from fruit of Swietenia macrophylla.

Five new limonoids, swieteliacates A-E (1-5) and a tirucallane-type triterpenoid, swietesenin (6), together with four known compounds (7-10) were isolated from fruit of Swietenia macrophylla. Their structures were determined by spectroscopic analyses. The new compounds were tested in vitro for their cytotoxic effects against five human cancer cell lines. Compound 2 exhibited moderate cytotoxic activities against SW480 and HL-60 cancer cell lines with IC50 values of 30.6 and 32.9µM, respectively.

A new sesquiterpene from Kalimeris integrifolia.

A new sesquiterpene kalinturoside A (1), and 17 known compounds friedelan-3-ol (2), 24-ethyl-5a-cholesta-7, 22(E)-dien-3-one (3), friedelin (4), syringaresinol (5), α-spinasterol (6), ciwujiatone (7), syringic acid (8), scopoletin (9), apocynin (10), 1-(3-hydroxy-4, 5-dimethoxyphenyl)ethan-1-one (11), apigenin (12), 5-hydroxymethylfurfural (13), stigmasterol-3-O-ß-d-glucopy-ranoside (14), bidenoside C (15), citrusin (16), irioresinol A (17) and syringaresinol-4-O-ß-d-glucopyranoside (18) were isolated from the herbs of Kalimeris integrifolia. The structures of these compounds were elucidated using spectroscopic techniques such as NMR and MS. All of the compounds were isolated from this genus for the first time.

New Acetylenic Acids and Derivatives from the Edible Mushroom Craterellus lutescens (Cantharellaceae).

Thirteen new acetylenic acids and their derivatives, craterellynes G-Q (1, 2, 4-10, 12, 13), 9-epi-craterellyne H (3), and 14-O-ethyl-craterellyne O (11), were isolated from the fruiting bodies of edible mushrooms Craterellus lutescens. The structures of these compounds were identified by various spectroscopic and chemical means. The stereoconfigurations of 1-13 were elucidated by the combination of acetonide formation, J-based configuration analysis, and modified Mosher's method. Craterellyne I exhibited cytotoxicities against human cancer strains and inhibition of nitric oxide (NO) production, as well as weak antimicrobial activity against Candida albicans.
