Effect of electroacupuncture on the inflammatory response in patients with acute pancreatitis: an exploratory study

Limbic system plasticity after electroacupuncture intervention in knee osteoarthritis rats

Knee osteoarthritis (KOA) is characterized by debilitating pain. Electroacupuncture (EA), a traditional Chinese medical therapy, has shown promise in KOA pain management. This study investigated the therapeutic potential of EA in KOA and its impact on limbic system neural plasticity. Sixteen rats were randomly assigned into two groups: EA group and sham-EA group. EA or sham-EA interventions were administered at acupoints ST32 (Futu) and ST36 (Zusanli) for three weeks. Post-intervention resting-state fMRI was scanned, assessing parameters including Amplitude of low frequency fluctuations (ALFF), regional homogeneity (ReHo), functional connectivity (FC) and nodal characterizations of network within limbic system. The results showed that EA was strategically directed towards the limbic system, resulting in discernible alterations in neural activity, FC, and network characteristics. Our findings demonstrate that EA had a significant impact on the limbic system neural plasticity in rats with KOA, presenting a novel nonpharmacological approach for KOA treatment.

Electroacupuncture for abdominal pain relief in patients with acute pancreatitis: A three-arm randomized controlled trial

BACKGROUND

Electroacupuncture (EA) may reduce the severity of acute pancreatitis (AP) and provide additional pain relief in patients with chronic pancreatitis. However, the ability of EA to relieve pain in patients with AP has not been well documented.

OBJECTIVE

This study was undertaken to compare the pain-relieving effects of EA and conventional treatment in patients with AP.

DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS

This study was conducted using a randomized, controlled, three-arm, parallel-group and multi-center design. Patients diagnosed with AP were randomly and equally assigned to EA1, EA2 or control groups. All participants received conventional standard-of-care therapy for AP. Local EA alone was administered in EA1, and local plus distal EA was given in EA2. Local EA included two abdominal acupoints, while distal EA included twelve peripheral acupoints. EA groups underwent one session of EA daily for 4 days (days 1-4), or until pain was resolved or discharged.

MAIN OUTCOME MEASURES

The primary outcome measure was the change in the visual analogue scale (VAS; 0-100) pain score between baseline and day 5.

RESULTS

Eighty-nine participants were randomized into EA1, EA2 and control groups, and 88 (EA1, 30; EA2, 29; control, 29) were included in the full-analysis set. VAS score change (median [interquartile range]) on day 5 was (12.3 ± 22.5) in the EA1 group, (10.3 ± 21.5) in the EA2 group, and (8.9 ± 15.2) in the control group. There were not significant differences in the change in VAS score among treatments (P = 0.983). However, time to food intake was significantly shorter in the EA group (EA1 + EA2) than in the control group (median 2.0 days vs 3.0 days), with a hazard ratio of 0.581 (P = 0.022; 95% CI, 0.366-0.924). No significant adverse events occurred.

CONCLUSION

EA treatment did not significantly reduce pain after 4 days of treatment in patients with AP-associated abdominal pain but significantly reduced time to first food intake.

Low-intensity pulsed ultrasound at ST36 improves the gastric motility by TNF-α/IKKβ/NF-κB signaling pathway in diabetic rats

BACKGROUND AND AIM

Low-intensity pulsed ultrasound (LIPUS) can effectively regulate the central and peripheral nervous system. However, whether LIPUS could act on acupuncture points to modulate the activity of peripheral nervous has rarely been studied. Our study aimed to investigate whether LIPUS at ST36 could improve gastric emptying in diabetic gastroparesis rats.

METHODS

Sprague-Dawley male rats were divided into three groups: control group (CON), diabetic gastroparesis group (DM), and diabetic gastroparesis LIPUS treated group (LIPUS). The body weight and blood glucose were recorded every week. Glucose tolerance, gastric emptying rate, and gastric motility were measured before and after treatment. Gastric motility was assessed by ultrasonic examination and Muscle strip experiment. The expression level of c-Kit was assessed by immunohistochemistry staining. Levels of TNF-α, p-NF-κB p-65, NF-κB p-65, and p-IKKβ, IKKβ were measured by western blot.

RESULTS

We reported LIPUS at an intensity of 0.88 W/cm2 exhibited significant differences in functional recovery of gastric delayed emptying in diabetic rats. Through ultrasound gastric motility functional testing and analysis of gastric antral smooth muscle strips indirectly and directly proved the effectiveness of LIPUS for the recovery of gastric delayed emptying. Pathological analysis and western blot indicated that the mechanism by which LIPUS applied to ST36 improved gastric motility may be partially attributed to the inhibition of the TNF-α/IKKβ/NF-κB signaling pathway, thereby rescuing the damaged interstitial cells of Cajal network.

CONCLUSION

LIPUS at ST36 improved the gastric motility and rescued the damaged networks of interstitial cells of Cajal. LIPUS may have a promising therapeutic potential for diabetic gastroparesis.

Clinical Effect of Electroacupuncture on Acute Pancreatitis: Efficacies and Mechanisms

Acute pancreatitis (AP) is a common acute abdomen and the number one cause of acute digestive hospitalizations in the United States. Abdominal pain is the main clinical manifestation of abdominal symptoms, so reducing the abdominal symptoms caused by inflammation is very important to alleviate the pain of patients. Electroacupuncture (EA) as a traditional Chinese medicine (TCM) therapy has significant conditioning effects on various inflammatory diseases including AP. Continuous studies in recent years have shown that EA conditioning has significant effects on reducing inflammation and regulating gastrointestinal symptoms in AP. At the same time, there is sufficient evidence to further elucidate the mechanism of EA. In this review, we will summarize the effect of EA on AP and its mechanism, so as to better serve clinical practice in the treatment of AP in the future.

The lower He-sea points playing a significant role in postoperative ileus in colorectal cancer treated with acupuncture: based on machine-learning

Background

Postoperative ileus (POI) is a common complication following abdominal surgery, which can lead to significant negative impacts on patients' well-being and healthcare costs. However, the efficacy of current treatments is not satisfactory. The purpose of this study was to evaluate the therapeutic effects of acupuncture intervention and explore the regulation of acupoint selection for treating POI in colorectal cancer (CRC) patients.

Methods

We searched eight electronic databases to identify randomized controlled trials (RCTs) on acupuncture for POI in CRC and conducted a meta-analysis. Subsequently, we utilized the Apriori algorithm and the Frequent pattern growth algorithm, in conjunction with complex network and cluster analysis, to identify association rules of acupoints.

Results

The meta-analysis showed that acupuncture led to significant reductions in time to first defecation (MD=-20.93, 95%CI: -25.35, -16.51; I2 = 93.0%; p < 0.01; n=2805), first flatus (MD=-15.08, 95%CI: -18.39, -11.76; I2 = 96%; p < 0.01; n=3284), and bowel sounds recovery (MD=-10.96, 95%CI: -14.20, -7.72; I2 = 94%; p < 0.01; n=2043). A subgroup analysis revealed that acupuncture not only reduced the duration of POI when administered alongside conventional care but also further expedited the recovery of gut function after colorectal surgery when integrated into the enhanced recovery after surgery (ERAS) pathway. The studies included in the analysis reported no instances of serious adverse events associated with acupuncture. We identified Zusanli (ST36), Shangjuxu (ST37), Neiguan (PC6), Sanyinjiao (SP6), Xiajuxu (ST39), Hegu (LI4), Tianshu (ST25), and Zhongwan (RN12) as primary acupoints for treating POI. Association rule mining suggested potential acupoint combinations including {ST37, ST39}≥{ST36}, {PC6, ST37}≥{ST36}, {SP6, ST37}≥{ST36}, and {ST25, ST37}≥{ST36}.

Conclusion

Meta-analysis indicates acupuncture's safety and superior effectiveness over postoperative care alone in facilitating gastrointestinal recovery. Machine-learning approaches highlight the importance of the lower He-sea points, including Zusanli (ST36) and Shangjuxu (ST37), in treating POI in CRC patients. Incorporating additional acupoints such as Neiguan (PC6) (for pain and vomiting) and Sanyinjiao (SP6) (for abdominal distension and poor appetite) can optimize treatment outcomes. These findings offer valuable insights for refining treatment protocols in both clinical and experimental settings, ultimately enhancing patient care.

Electroacupuncture Alleviates 46-Trinitrobenzene Sulfonic Acid-Induced Visceral Pain via the Glutamatergic Pathway in the Prefrontal Cortex

Visceral pain caused by inflammatory bowel disease (IBD) greatly diminishes the quality of life in affected patients. Yet, the mechanism of how IBD causes visceral pain is currently not fully understood. Previous studies have suggested that the central nervous system (CNS) and gut-brain axis (GBA) play an important role in IBD-inducing visceral pain. As one of the treatments for IBD, electroacupuncture (EA) has been used to treat various types of pain and gastrointestinal diseases in clinical practice. However, whether EA relieves the visceral pain of IBD through the gut-brain axis has not been confirmed. To verify the relationship between visceral pain and CNS, the following experiments were conducted. ¹H-NMR analysis was performed on the prefrontal cortex (PFC) tissue obtained from IBD rat models to determine the link between the metabolites and their role in EA treatment against visceral pain. Western blot assay was employed for detecting the contents of glutamate transporter excitatory amino acid transporters 2 (EAAT2) and the glutamate receptor N-methyl-D-aspartate (NMDA) to verify whether EA treatment can alleviate neurotoxic symptoms induced by abnormal increases of glutamate. Study results showed that the glutamate content was significantly increased in the PFC of TNBS-induced IBD rats. This change was reversed after EA treatment. This process was associated with increased EAAT2 expression and decreased expression of NMDA receptors in the PFC. In addition, an increase in intestinal glutamic-metabolizing bacteria was observed. In conclusion, this study suggests that EA treatment can relieve visceral pain by reducing glutamine toxicity in the PFC, and serves an alternative clinical utility.

Study on the effect of acupunture treatment on autonomic nerve dysfunction in convalescent period of stroke based on heart rate variability assessment technique

Stroke patients with autonomic dysfunction are more likely to develop cardiac problems, which have been linked to lower functional outcomes and increased mortality. In this study, heart rate variability (HRV) detection paired with the Clinical Feature Scale will be utilized to elucidate the immediate impact of manual acupuncture on autonomic dysfunction of varying severity in the convalescence stroke phase. This is a randomized, single-blind, controlled clinical trial approach. At a ratio of 1:1, 60 appropriate patients will be randomly randomized into either the experimental or control group. On the basis of symptomatic treatment drugs, the experimental group will additionally undertake acupuncture therapy 3 times a week for 4 weeks, for a total of 12 times. Primary outcomes include 24-hour HRV and 60-minute HRV detection at week 4 compared with baseline. The secondary outcome is the score of clinical feature scale at week 4 compared with the baseline. Adverse events and safety indices will be recorded throughout the experiment. The SPSS V.25.0 statistical program was applied for analysis, and measurement data were expressed as mean ± SD.

Effect of electroacupuncture combined with rehabilitation training on hypertension: A systematic review and meta-analysis

To evaluate the clinical effects of electroacupuncture combined with rehabilitation training (EART) versus conventional rehabilitation training (CRT) on hypertension. Multiple databases like PubMed, Embase, Web of Science and Wanfang database, China National Knowledge Internet database, and Chinese Biological Medical database were used to search for the relevant studies and full-text articles involved in evaluating EART versus CRT with hypertension. Review Manager 5.4 was used to estimate the effects of the results among included articles. Forest plots, sensitivity analysis, and funnel plots were also conducted on the included articles. In this meta-analysis study, there were 9 relevant studies were eventually satisfied the included criteria. There were significant differences between EART group and CRT group in systolic blood pressure after treatment (MD -16.62, 95 %CI = -21.84 to -11.39; P < 0.00001), diastolic blood pressure after treatment (MD = -16.03, 95 % CI = -21.55 to -10.50; P < 0.00001), and effective rate (MD = 1.22, 95 % CI = 1.13 to 1.32; P < 0.00001). Sensitivity analysis and funnel chart demonstrated that the study was robust and limited publication bias was observed. Our data showed that EART was clinically more significant than CRT in hypertension. Further studies need to be performed using large relevance references to verify the effectiveness of EART in the treatment of hypertension.

The NLR family pyrin domain containing 3 inflammasome in the mechanism of electroacupuncture: Current status and future perspectives

Electroacupuncture, which is the most widely used alternative medicine treatment, has been gradually recognized for its effectiveness; however, its mechanism of action is not fully understood. The NLR family pyrin domain containing 3 (NLRP3) inflammasome is a thoroughly studied inflammasome that is closely associated with Alzheimer’s disease, spinal cord injury, and other diseases and plays an important role in the diagnosis and treatment of human immune system diseases. In recent years, some scholars have found that the NLRP3 inflammasome is a part of the mechanism of action of electroacupuncture, which has attracted further attention. In the current review, using “electroacupuncture” and “NLRP3 inflammasome” as keywords and based on the existing randomized controlled trials or clinical trials, we summarize the mechanisms of electroacupuncture targeting NLRP3 inflammasome in the treatment of different diseases and discuss how to optimize the electroacupuncture protocol to obtain thorough mechanisms of NLRP3 inflammasome in electroacupuncture and improve the level of evidence.

Anti-Inflammatory Effects of Acupuncture at ST36 Point: A Literature Review in Animal Studies

So far, a number of acupuncture studies have shown anti-inflammatory effects of acupuncture treatment, mostly known at specific point ST36. However, there is no literature that oversaw the inflammation-regulatory effects of acupuncture in each tissue. Therefore, we investigated how acupuncture at specific acupoint ST36 regulates inflammation and its underlying mechanisms. We searched literatures on PubMed until July 2021 using the keywords “animal, acupuncture, ST36, inflammation, immune,” and 292 literatures were searched. We ultimately selected 69 studies to determine the anti-inflammatory actions of acupuncture at ST36 and classified the changes of inflammatory mediators according to target regions. Forty-three studies were included in body fluids, 27 studies in the digestive system, 17 studies in the nervous system, and 30 studies in other tissues or organs. In this review, we found that acupuncture at ST36 has clinical benefits in relieving inflammation through several mechanisms such as vagus nerve activation, toll-like receptor 4 (TLR4)/NF-κB signaling, macrophage polarization, mitogen-activated protein kinase (MAPK) signaling pathway, and cholinergic anti-inflammatory pathway. We expect that these data will inform further studies related to ST36 acupuncture on inflammation.

Progress in research of hyperlipidemic acute pancreatitis

With the continuous change of dietary structure and other factors, the incidence of hyperlipidemic acute pancreatitis (HLAP) has increased year by year. In particular, HLAP is different from other types of acute pancreatitis in its mechanism, so its clinical diagnosis and treatment have its own particularity. In this paper, we review the progress in the research of HLAP.

Electroacupuncture Ameliorates Acute Pancreatitis: A Role for the Vagus Nerve-Mediated Cholinergic Anti-Inflammatory Pathway

Organ failure resulting from excessive inflammation is the leading cause of death in the early phase of acute pancreatitis (AP). The autonomic nervous system was reported to be involved in AP, and the vagus nerve could exert anti-inflammatory effects through α7 nicotinic acetylcholine receptor (α7nAChR) signaling. Acupuncture has been widely used in traditional Asian medicine, and recent studies suggested the inflammation modulating effect of electroacupuncture (EA) might be mediated by the autonomic nervous system. In this study, we aimed to investigate the effects of EA in AP animal models. Two independent AP mouse models were used, namely, caerulein hyperstimulation and pancreatic duct ligation. We found that EA at Zusanli acupoint increased vagus nerve activity, suppressed systemic inflammation, and alleviated the histopathological manifestations and leukocyte infiltrations of the pancreas. Induction of AP resulted in a remarkable decrease in the frequency of α7nAchR⁺ macrophages in the pancreas, while EA counteracted this phenomenon. The anti-inflammatory, pancreatic protective and upregulation of α7nAchR effects of EA were reduced in mice with vagotomy. Moreover, the therapeutic effects of EA were attenuated in mice treated with methyllycaconitine citrate, a selective α7nAChR antagonist. Taken together, EA could modulate inflammation, thereby exerting protective effects in AP. The mechanism may include activating the vagus nerve through the cholinergic anti-inflammatory pathway.

Efficacy of Acupuncture and Moxibustion as a Subsequent Treatment after Second-Line Chemotherapy in Advanced Gastric Cancer

Objective

To explore whether acupuncture and moxibustion can prevent disease progression of advanced gastric cancer patients completing second-line chemotherapy and, if so, the related mechanism.

Method

Progression-free survival (PFS) and overall survival (OS) were main outcome measures. The real-time quantitative PCR was used to detect the expression of genes including T-bet, IFN-γ, GATA3, and IL-4 in peripheral blood mononuclear cells (PBMCs). IL-4, IL-6, Ca199, CRP, and IFN-γ in plasma levels were checked.

Results

170 patients were randomly assigned in a 3 : 2 ratio to receive either acupuncture and moxibustion or sham acupuncture until progression. 135 patients were included in the primary analysis. Both PFS and OS in treatment group were proven to be better than control group. Acupuncture and moxibustion promoted typical Th1 cells drifting, as confirmed by increased T-bet/IFN-γ and decreased GATA3/IL-4 in mRNA levels from PBMCs, as well as upregulating IFN-γ and downregulating IL-4 in plasma levels. IL-6, Ca199, and CRP in plasma levels were also reduced by acupuncture and moxibustion.

Conclusions

Acupuncture and moxibustion can prolong PFS and OS of advanced gastric cancer patients completing second-line chemotherapy by reversing Th1/Th2 shift and attenuating inflammatory responses.

Acupuncture attenuates postoperative inflammation in patients after craniotomy: A prospective, open-label, controlled trial

BACKGROUND

It is important to manage inflammation after craniotomy. It may be prudent to reduce the excessive usage of antibiotics and to add supplementary treatments like acupuncture, which would be effective and safe. However, there are only a few studies available to date on the effects of acupuncture on anti-inflammatory response after craniotomy. The aim of this study was to explore the anti-inflammatory effects of acupuncture in patients after a craniotomy.

METHODS

This study was a single-center, prospective, open-label, controlled trial. Forty-four subjects who underwent craniotomy for an unruptured aneurysm, facial spasm, or brain tumor were allocated to either an acupuncture group or a control group. Both groups received postoperative routine care in the Department of Neurosurgery. The subjects in the acupuncture group also received a total of 6 acupuncture treatments sessions within 8 days after craniotomy. Acupuncture treatments included acupuncture, electroacupuncture, and intradermal acupuncture. The serum interleukin (IL)-1β and IL-6, tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), and erythrocyte sedimentation rate levels were assessed four times within 7 days after surgery. The presence of fever, use of additional antibiotics, presence of infection including pneumonia or urinary tract infection, and safety were also reviewed.

RESULTS

The IL-1β levels of subjects who underwent aneurysmal clipping were significantly lower in the acupuncture group (P = .02). TNF-α levels of subjects who underwent aneurysmal clipping at the seventh postoperative day were also significantly lower in the acupuncture group (P = .03). Six cases of fever of unknown origin were observed in the control group, while none were seen in the acupuncture group, revealing that the incidence of fever was significantly lower in the acupuncture group (P = .02). No adverse events occurred during the trial.

CONCLUSION

Acupuncture showed a possibility of alleviating inflammation by attenuating the levels of proinflammatory cytokines and significantly reduced the incidence of fever of unknown origin in patients after craniotomy. Acupuncture would be suitable as an adjunctive therapy to alleviate inflammation after craniotomy.

Acupuncture for Acute Pancreatitis: A Systematic Review and Meta-analysis

OBJECTIVE

The objective of this study was to assess the efficacy and safety of acupuncture plus routine treatment (RT) for acute pancreatitis (AP).

METHODS

Literature searches were performed in 8 databases up to October 31, 2018. Randomized controlled trials comparing acupuncture plus RT with RT alone for AP were included.

RESULTS

Twelve eligible studies were included finally. The meta-analysis showed that acupuncture plus RT compared with RT alone could significantly improve the total effective rate and gastrointestinal function and reduce the Acute Physiology, Age, Chronic Health Evaluation II score, tumor necrosis factor α count, the time of resuming to diets, and the length of hospital stay. Only 3 of the studies reported adverse events or reactions.

CONCLUSIONS

This study suggested that acupuncture combined with RT may be effective for AP. However, more rigorously designed randomized controlled trials are warranted to confirm the current findings.

The consensus of integrative diagnosis and treatment of acute pancreatitis-2017

Acute pancreatitis (AP) is one of the most common acute abdominal diseases. The digestive disease committee, Chinese Association of Integrative Medicine, released Integrated traditional Chinese and Western medicine for diagnosis and treatment of acute pancreatitis in 2010.¹ Since then, further studies and great progress have been made by domestic and foreign counterparts from the perspective of both Chinese and Western medicine in AP, including the classification, fluid resuscitation, organ function maintenance, surgery intervention, enteral nutrition (EN), and syndrome differentiation and treatment. It is necessary to update the consensus on diagnosis and treatment of integrated Chinese and Western medicine to meet clinical needs. Therefore, the 2012 Revision of the Atlanta Classification Standard (RAC) by the International AP Consensus,² the 2013 the Management of Acute Pancreatitis by the American College of Gastroenterology,^{3, 4} the 2014 Guidelines for diagnosis and treatment of the acute pancreatitis guide (2014) by the Chinese medical association branch,⁵ the 2014 Guidelines on Integrative Medicine for Severe Acute Pancreatitis by the General Surgery Committee of the Chinese Society of Integrated Traditional Chinese and Western Medicine,⁶ and Traditional Chinese Medicine Consensus on the Diagnosis and Treatment for Acute Pancreatitis by the Spleen and Stomach committee of China Association of Traditional Chinese Medicine^{7, 8} were taken into account for the revision of the consensus published in 2010. The digestive specialists in Chinese and Western medicine had a discussion on traditional Chinese medicine (TCM) types, syndrome differentiation, the main points of integrative medicine, and so on. According to the Delphi method, Consensus of Integrative Diagnosis and Treatment of Acute Pancreatitis (the 2017 revision) has been passed after three rounds votes. (The voting options are as follows: (a) totally agree; (b) agree, but with some reservations; (c) agree, but with larger reservations; (d) disagree, but reserved; and (e) absolutely disagree. If more than two out of three choose (a), or over 85% choose (a) + (b), the consensus will be passed.) The final validation was carried out by the core expert group in Taizhou, Jiangsu on June 9, 2017. The full text is as follows.

Electroacupuncture Improves Intestinal Dysfunction in Septic Patients: A Randomised Controlled Trial

Objective

To investigate the effects of electroacupuncture (EA) at “Zusanli” (ST36) and “Shangjuxu”(ST37) on reducing inflammatory reaction and improving intestinal dysfunction in patients with sepsis-induced intestinal dysfunction with syndrome of obstruction of the bowels Qi.

Methods

A total of 71 patients with sepsis-induced intestinal dysfunction with syndrome of obstruction of the bowels Qi were randomly assigned to control group (n=36) and treatment group (n=35). Patients in control group were given conventional therapies including fluid resuscitation, anti-infection, vasoactive agents, mechanical ventilation, supply of enteral nutrition, and glutamine as soon as possible. In addition to conventional therapies, patients in treatment group underwent 20 minutes of EA at ST36-ST37 twice a day for five days. At baseline, day 1, day 3, and day 7 after treatment, the plasma levels of procalcitonin (PCT), tumor necrosis factor-α (TNF-α), intestinal fatty acid-binding proteins (I-FABP), D-lactate, citrulline, and TCM quantitative score of intestinal dysfunction were measured and recorded, respectively. And days on mechanical ventilation (MV), length of stay in intensive care unit (ICU), and 28d mortality were recorded.

Results

During treatment, the plasma levels of PCT, TNF-α, I-FABP, D-lactate, and TCM quantitative score of intestinal dysfunction were declining in both groups, while the treatment group showed a significant decline (P<0.05). Plasma levels of citrulline were increasing in both groups, while the treatment group showed a significant increase (P<0.05). However, there were no significant differences in the days on MV, length of stay in ICU, and 28d mortality between two groups (P>0.05).

Conclusions

EA at ST36-ST37 can reduce inflammatory reaction and has protective effects on intestinal function in patients with sepsis-induced intestinal dysfunction with syndrome of obstruction of the bowels Qi.

Electroacupuncture for abdominal pain relief in patients with acute pancreatitis: study protocol for a randomized controlled trial

BACKGROUND

Previous studies have shown that electroacupuncture (EA) reduces the severity of acute pancreatitis. However, the effect of EA for pain relief in patients with acute pancreatitis has not been evaluated yet. The purpose of this study was to prove the efficacy of EA for pain relief in patients with acute pancreatitis compared with conventional treatment.

METHODS

This study is a randomized, controlled, three-arm, parallel-group, multi-center trial. Patients diagnosed with acute pancreatitis are enrolled and randomly assigned to EA 1, EA 2, or a control group in a 1:1:1 ratio. All the enrolled patients basically receive the conventional standard-of-care therapy for acute pancreatitis. Local EA is given in group EA 1, while local with additional distal EA is given in group EA 2. Local EA includes two acupoints, Zhong Wan (CV12) and Shang Wan (CV13), located in the abdomen, while distal EA includes 12 peripheral acupoints, Zhong Wan (CV12), Shang Wan (CV13), He Gu (LI4), Nei Guan (PC6), San Yin Jiao (SP6), Xuan Zhong (GB39), Zu San Li (ST36), and Shang Ju Xu (ST37). The patients randomized to the EA 1 and EA 2 groups undergo one session of EA daily from day 1 until day 4, or until pain resolves. The primary endpoint is the Visual Analog Scale (VAS) change for pain on day 5. Secondary endpoints include daily VAS, requirement of analgesics, changes of inflammatory markers, time to pain disappearance, and hospital days.

DISCUSSION

The results of this trial are expected to prove the efficacy of EA for pain relief in patients with acute pancreatitis. Based upon the results, EA would be applied to a variety of clinical practices for reducing pain.

TRIAL REGISTRATION

This trial is registered at ClinicalTrials.gov, ID: NCT03173222 . Registered on 1 August 2017.

Electro-acupuncture attenuates inflammatory responses and intraabdominal pressure in septic patients: A randomized controlled trial

BACKGROUND

A pathological increase in intraabdominal pressure (IAP) and inflammatory responses have negative effects on splanchnic, respiratory, cardiovascular, renal, and neurological function in septic patients with intestinal dysfunction. Electro-acupuncture (EA) has been evidenced to have a bidirectional neuron-endocrine-immune system regulating effect in patients with intestinal dysfunction. The purpose of current study was to evaluate the effects of EA at "Zusanli" (ST36) and "Shangjuxu" (ST37) on inflammatory responses and IAP in septic patients with intestinal dysfunction manifested syndrome of obstruction of the bowels Qi.

METHODS

Eighty-two septic patients with intestinal dysfunction manifested syndrome of obstruction of the bowels Qi were randomly assigned to control group (n = 41) and EA group (n = 41). Patients in control group were given conventional therapies including fluid resuscitation, antiinfection, vasoactive agents, mechanical ventilation (MV), supply of enteral nutrition, and glutamine as soon as possible. In addition to conventional therapies, patients in EA group underwent 20-minutes of EA at ST36-ST37 twice a day for 5 days. At baseline, posttreatment 1, 3, and 7 days, serum levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) and IAP levels, were measured, respectively. And days on MV, length of stay in intensive care unit (ICU) and 28 days mortality were recorded.

Pharmacokinetics and pharmacodynamics of Shengjiang decoction in rats with acute pancreatitis for protecting against multiple organ injury

AIM

To explore the pharmacokinetics and pharmacodynamics of Shengjiang decoction (SJD) in rats with acute pancreatitis (AP) for protecting against multiple organ injury.

METHODS

An AP model was established by retrograde perfusion of 3.5% sodium taurocholate into the biliopancreatic duct, and a control group (CG) received 0.9% sodium chloride instead. Twelve male Sprague-Dawley rats were randomly divided into a CG treated with SJD (CG + SJD) and a model group treated with SJD (MG + SJD), both of which were orally administered with SJD (5 g/kg) 2 h after surgery. Blood samples were collected via the tail vein at 10, 20, and 40 min and 1, 2, 3, 4, 6, 8, and 12 h after a single dose of SJD to detect its main components using high-performance liquid chromatography-tandem mass spectrometry. The pharmacokinetic parameters were compared. In the pharmacodynamic experiment, 18 male Sprague-Dawley rats were randomly divided into a CG, an AP model group (MG), and an SJD treated AP group (SJDG). Serum amylase, lipase, and inflammatory cytokines were measured, and heart, lung, liver, spleen, pancreas, kidney, and intestine tissues were collected for pathological examination.

RESULTS

The MG + SJD displayed significantly shorter mean residence time (MRT) and higher clearance (CL) for emodin and aloe-emodin; significantly shorter time of maximum concentration and T_1/2 and a lower area under curve (AUC) for aloe-emodin; a significantly higher AUC and lower CL for rhein; and longer MRT and lower CL for chrysophanol than the CG + SJD. In the pharmacodynamic experiment, the amylase, interleukin (IL)-6, IL-10, and tumor necrosis factor (TNF)-α levels in the MG were higher than those in the CG (P < 0.05). After the herbal decoction treatment, the SJDG had higher IL-10 and lower TNF-α levels than the MG (P < 0.05). The MG had the highest pathological scores, and the pathological scores of the lung, pancreas, kidney, and intestine in the SJDG were significantly lower than those in the MG (P < 0.05).

CONCLUSION

AP may have varying effects on the pharmacokinetics of the major SJD components in rats. SJD might alleviate pathological injuries of the lung, pancreas, kidney, and intestine in rats with AP via regulating pro- and anti- inflammatory responses, which might guide the clinical application of SJD for AP treatment.

Acupressure for respiratory allergic diseases: a systematic review of randomised controlled trials

OBJECTIVE

To evaluate the effects and safety of acupressure for the management of respiratory allergic diseases by systematically reviewing randomised controlled trials (RCTs).

METHODS

A total of 13 electronic English and Chinese databases were searched until July 2017. Two authors extracted data and evaluated risk of bias independently. Review Manager V.5.3 was employed for data analysis.

RESULTS

The literature search identified 186 papers, of which only four of met the inclusion criteria: two for allergic rhinitis (AR) and two for asthma. High and unclear risk of bias existed across all the included studies. The findings demonstrated that acupressure greater effects on the relief of nasal symptoms of AR compared with 1% ephedrine nasal drop plus thermal therapy. With either Western medicine or Chinese herbal medicine as a cointervention, one study indicated that acupressure plus salbutamol was led to a significantly greater improvement of pulmonary function for patients with asthma compared with salbutamol only. However, the remaining two studies indentified no significant differences in any outcome measures between the two groups.

CONCLUSIONS

No reliable conclusions regarding the effects of acupressure on AR and asthma could be drawn by this review due to the small number of available trials with significant heterogeneity of study design and high/unclear risk of bias. Further, more rigorously designed RCTs are needed. Acupressure seems safe for symptomatic relief of AR and asthma, although larger studies are required to be able to robustly confirm its safety.

Anti-inflammatory and immune regulatory effects of acupuncture after craniotomy: study protocol for a parallel-group randomized controlled trial

BACKGROUND

Despite recent advances in the medical and surgical fields, complications such as infection, pneumonia, or brain swelling may occur after a craniotomy. In some patients, perioperative antibiotic prophylaxis causes adverse effects such as itching, rash, or digestive conditions. Certain patients still develop infections severe enough to require a repeat operation despite antibiotic prophylaxis. Acupuncture has been used to treat inflammatory conditions, and many basic and clinical studies have provided evidence of its anti-inflammatory and immune regulatory effects. The aim of this study is to explore the effects of acupuncture on inflammation and immune function after craniotomy.

METHODS

This trial will be a single-center, parallel-group clinical trial. Forty patients who underwent craniotomy for an unruptured aneurysm, facial spasm, or a brain tumor will be allocated to either the study or the control group. The study group will receive conventional management as well as acupuncture, electroacupuncture, and intradermal acupuncture, which will start within 48 h of the craniotomy. The patients will receive a total of six sessions within 8 days. The control group will only receive conventional management. The primary outcome measure will be the C-reactive protein levels, while the secondary outcomes will be the serum erythrocyte sedimentation rate and the tumor necrosis factor-α, interleukin (IL)-1β, and IL-6 levels measured at four different time points: within 48 h prior to the craniotomy and on days 2, 4, and 7 after surgery. The presence of fever and infection, the use of additional antibiotics, the presence of infection, including pneumonia or urinary tract infection, and safety will also be investigated.

DISCUSSION

In this trial, we will observe whether acupuncture has anti-inflammatory and immune regulatory effects after a craniotomy. If our study yields positive results and a placebo-controlled study also finds favorable results following our study, acupuncture could be recommended as an adjunctive therapy after a craniotomy.

Effect of Stress-Free Therapy on immune system: Induction of Interleukin 10 expression in lymphocytes through activation of CD19(+) CD24(hi) CD38(hi) regulatory B Cells

BACKGROUND AND AIMS

Mild thermal treatment with "Pinpoint Plantar Long-wavelength Infrared Light Irradiation (PP-LILI)" named as Stress-Free Therapy(®) increases peripheral-deep body temperature and blood flow, and improves multiple disorders including hyperpiesia, type II diabetes and cardiovascular patients. Immunomodulatory effects of PP-LILI were investigated.

MATERIALS AND METHODS

Seven healthy individuals and 4 people with underlying medical condition (UMC) participated in this study. Participants were given PP-LILI stimuli twice a week over 3 weeks and followed with placebo stimuli over 3 weeks. This set of sessions was repeated 3 times. For analyses, fresh peripheral mononuclear cells from participants were stained with fluorescencedye conjugated monoclonal antibodies and changes in populational compositions and IL-10 expression levels were observed by flow cytometry.

RESULTS

Distinct expression of IL-10 in lymphocytes was induced by PP-LILI from the second session in the healthy individuals. This induction was terminated during the following placebo sessions. PP-LILI induced activation of CD19(+) CD24(hi) CD38(hi) regulatory B cells in every session prior to induce the IL-10 in major lymphocytes. Activated regulatory B cells in the individuals with UMC decreased as same levels of healthy individuals after second PP-LILI session and re-activated with the stimuli. Significant population changes in neither regulatory T cells nor proinflammatory IL-17A expressing CD4(+) T cells were observed.

CONCLUSIONS

PP-LILI is a potent immunomodulatory inducer that activates regulatory B cells and consequent IL-10 expression in lymphocytes. Moreover, its stimulatory intervals down-regulate the higher activation of regulatory B cells and lymphocyte's IL-10 expression occurred by UMC to the healthy people's level.
