The Efficacy and Safety of Acupuncture for Preventing Radiation Pneumonitis in Patients With Lung Cancer: A Prospective, Single-Blinded, Randomized Pilot Proof-of-Principle Study

Acupuncture for dyspnea and breathing physiology in chronic respiratory diseases: A systematic review and meta-analysis of randomized controlled trials

Background

Dyspnea, a common symptom of chronic respiratory diseases (CRDs), is closely linked to higher levels of functional impairment and death, leading to significant societal and financial challenges. Despite numerous clinical trials and systematic reviews suggested the potential benefits of acupuncture for chronic obstructive pulmonary disease (COPD) and lung cancer, there is currently insufficient evidence to conclusively prove its effectiveness in alleviating dyspnea in patients with CRDs.

Methods

To compile and evaluate the existing data on the effectiveness and safety of acupuncture for managing dyspnea in CRDs. Randomized controlled trials investigating acupuncture for the treatment of dyspnea in patients with CRDs, such as COPD, lung cancer, asthma, bronchiectasis, interstitial lung disease, chronic pulmonary heart disease and bronchitis, were searched and retrieved from five electronic databases in English or Chinese.

Results

A total of 23 studies meeting the inclusion criteria were found in databases, covering various CRDs such as COPD, lung cancer, and asthma. A meta-analysis that compared acupuncture to a control group (which included no acupuncture and sham acupuncture) found significant advantages for acupuncture in reducing dyspnea severity (P = 0.0003), increasing 6MWD (P < 0.00001), improving quality of life measured by St. George's Respiratory Questionnaire (P = 0.03) and karnofsky performance status score (P < 0.00001). No significance was found in breathing physiology represented by FEV1 (P = 0.34) and FVC (P = 0.15). There was a comparable incidence of negative outcomes in both groups (P = 0.07). Results were consistent when compared to sham acupuncture. In addition, subgroup analyses were also consistent when different diseases or types of acupuncture were analyzed.

Conclusions

Acupuncture may be an effective and safe non-pharmacological complementary intervention to relief dyspnea for patients with CRDs. Nevertheless, research with high quality and large sample sizes is needed for further investigation.

Transcutaneous electrical acupoint stimulation improves pulmonary function by regulating oxidative stress during one-lung ventilation in patients with lung cancer undergoing thoracoscopic surgery: a randomized controlled trial

BACKGROUND

Our aim was to evaluate the efficacy of transcutaneous electrical acupoint stimulation (TEAS) on oxidative stress induced by one-lung ventilation, lung function, and postoperative quality of recovery in patients with lung cancer.

METHODS

The participants (n = 80) were assigned to the sham group and TEAS group. TEAS on bilateral Feishu (BL13), Zusanli (ST36), and Hegu (L14) was performed 30 minutes before induction of anesthesia and continued until the end of the surgery. In the sham group, the same acupoints were selected without electrical stimulation. PaO2/FiO2, intrapulmonary shunt ratio (Qs/Qt), alveolar-arterial oxygen tension (A-aDO2), and respiratory index (RI) were calculated to evaluate lung function before one-lung ventilation (T0), 30 min after one-lung ventilation (T1), 1 h after one-lung ventilation (T2), and 10 min after resuming two-lung ventilation (T3). The levels of malondialdehyde (MDA) and superoxide dismutase (SOD) were detected to estimate oxidative stress at T0, T1, T2, and T3. Secondary outcomes included removal time of thoracic drainage tube, duration of intensive care unit (ICU) stay, length of postoperative hospitalization, the incidence of postoperative pulmonary complications, and the Quality of Recovery-15 (QoR-15) score on postoperative day 1 and 2.

RESULTS

TEAS significantly increased PaO2/FiO2 at T1 and T2, while Qs/Qt, A-aDO2, and RI decreased remarkably from T1 to T3 (P < 0.05). Meanwhile, TEAS obviously decreased MDA and increased SOD activity at T2 and T3 (P < 0.05). Furthermore, TEAS also markedly shortened the length of ICU stay and hospital stay after surgery, whereas the QoR-15 score on postoperative day 1 and 2 was significantly higher (P < 0.05).

CONCLUSIONS

TEAS could reduce oxidative lung injury during one-lung ventilation, thereby protecting pulmonary function and effectively accelerating the early recovery of patients with lung cancer.

Effect of Electroacupuncture on the Treatment of Pneumonia in Patients with Hypertensive Intracerebral Hemorrhage

OBJECTIVE

Pneumonia is a serious postoperative complication of hypertensive intracerebral hemorrhage (HICH), and there is no specific treatment for pneumonia. In this study, we conducted randomized controlled trials to evaluate the effects of electroacupuncture (EA) on the treatment of pneumonia in patients with HICH.

METHODS

An equal number of patients with HICH complicated with pneumonia (n = 80 in total) were randomly placed in either the EA group (EA treatment and routine basic treatment) or the control group (routine basic treatment). After 14 days of treatment, clinical symptoms and signs, blood oxygen saturation, the level of inflammatory factors, the effective rate, the scores of the Barthel Index, National Institutes of Health Stroke Scale and Glasgow Coma Scale, the hospitalization time, and expenses were compared between the groups.

RESULTS

The general information of the patients in the control and EA groups were similar. After 14 days of intervention, the patients in the EA group showed better symptom and sign scores, blood oxygen saturation levels, Barthel Index scores, Glasgow Coma Scale scores, and National Institutes of Health Stroke Scale scores than the patients in the control group. Furthermore, the EA treatment also lowered the levels of inflammatory factors and white blood cell count. Additionally, the patients in the EA group showed higher effective rates than those in the control group.

CONCLUSIONS

EA benefits the treatment of pneumonia in patients with HICH.

Safety of acupuncture in oncology: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Acupuncture is frequently used to treat the side effects of cancer treatment, but the safety of this intervention remains uncertain. The current meta-analysis was conducted to assess the safety of acupuncture in oncological patients.

METHODS

The PubMed, Cochrane Central Register of Controlled Trials, and Scopus databases were searched from their inception to August 7, 2020. Randomized controlled trials in oncological patients comparing invasive acupuncture with sham acupuncture, treatment as usual (TAU), or any other active control were eligible. Two reviewers independently extracted data on study characteristics and adverse events (AEs). Risk of bias was assessed using the Cochrane Risk of Bias Tool.

RESULTS

Of 4590 screened articles, 65 were included in the analyses. The authors observed that acupuncture was not associated an with increased risk of intervention-related AEs, nonserious AEs, serious AEs, or dropout because of AEs compared with sham acupuncture and an active control. Compared with TAU, acupuncture was not associated with an increased risk of intervention-related AEs, serious AEs, or drop out because of AEs but was associated with an increased risk for nonserious AEs (odds ratio, 3.94; 95% confidence interval, 1.16-13.35; P = .03). However, the increased risk of nonserious AEs compared with TAU was not robust against selection bias. The meta-analyses may have been biased because of the insufficient reporting of AEs in the original randomized controlled trials.

CONCLUSIONS

The current review indicates that acupuncture is as safe as sham acupuncture and active controls in oncological patients. The authors recommend researchers heed the CONSORT (Consolidated Standards of Reporting Trials) safety and harm extension for reporting to capture the side effects and better investigate the risk profile of acupuncture in oncology.

LAY SUMMARY

According to this analysis, acupuncture is a safe therapy for the treatment of patients with cancer. Acupuncture seems to be safe compared with sham acupuncture and active controls.

To Explore the Effects of Acupuncture and Medical Treatment at Different Times on the Gastrointestinal Reaction and White Blood Cell Count of Patients with Lung Cancer Chemotherapy

Objective

To explore and analyze the effects of acupuncture and medical treatment at different times on the gastrointestinal reaction and leukocyte count of patients with lung cancer undergoing chemotherapy.

Methods

Select 224 lung cancer chemotherapy patients admitted to our hospital and randomly divide them into three groups: control group (n = 76), study 1 group (n = 78), and study 2 group (n = 70). The control group was treated with tropisetron hydrochloride for 30 minutes before chemotherapy. Study 1 group was given tropisetron hydrochloride and acupuncture combination therapy 30 minutes before chemotherapy. Study 2 group was given tropisetron hydrochloride treatment 30 min before chemotherapy and acupuncture treatment 30 min after chemotherapy. Collect patients' general information and compare the three groups of white blood cell count, G-CSF, GM-CSF levels, quality of life and KPS score, platelets, neutrophils, hemoglobin levels, TCM symptom scores, and the degree of digestive tract reaction.

Results

The data of the control group and study groups 1 and 2 are comparable in gender, age, pathological type, etc. (P > 0.05). Before treatment, the white blood cell counts of the three groups were not significantly different (P > 0.05), significantly reduced after treatment, but the difference between the groups was not statistically significant (P > 0.05). The levels of G-CSF and GM-CSF in the three groups were not substantially different before treatment (P > 0.05). The levels of G-CSF and GM-CSF were considerably lowered in all three groups, although the drop in the study group was more significant (P > 0.05) when compared to that in the control group. Before treatment, the quality of life and KPS score of the three groups were not statistically different (P > 0.05). The three groups' quality of life and KPS scores fell after treatment, with the study 1 group experiencing the greatest reduction, followed by the study 2 group and the control group. The levels of platelets, neutrophils, and hemoglobin in all three groups declined dramatically, with the most noticeable reduction in the control group, followed by study 2 and study 1. The difference between the three groups was statistically significant (P < 0.05). The TCM symptom scores of the three groups showed an upward trend, but compared with those of the study 1 group and study 2 group, the TCM symptom scores of the control group increased significantly and the difference between the three groups was statistically significant (P < 0.05). The effective rates of the control group, study group 1, and study group 2 were 42.11%, 82.05%, and 62.86%, respectively; compared with that of the control group, the treatment efficiency of study groups 1 and 2 was higher and the difference between the three groups was statistically significant (P < 0.05).

Conclusion

Tropisetron hydrochloride is an effective treatment for patients with lung cancer before chemotherapy, which can effectively improve the side effects of nausea and vomiting caused by chemotherapy, reduce the white blood cell count, and improve the quality of life of patients; it plays an important role in the improvement of prognosis.

Serum MMP-9 and SAA in the Diagnosis of Severe Pneumonia Caused by Radiotherapy of Esophageal Cancer

OBJECTIVE

To explore the relationship and diagnostic value of serum MMP-9 and SAA in severe pneumonia (sCAP) caused by radiotherapy of esophageal cancer.

METHODS

A total of 144 esophageal cancer patients who underwent radiotherapy in our hospital from April 2016 to February 2018 were collected. Among them, 58 patients without radiation pneumonitis (RP) were in the control group, 49 patients with grade 1∼2 RP were in the radiation group, and 37 patients with sCAP were in the severe group. The levels of serum MMP-9 and SAA in every group of patients were detected. The ROC curve was used to determine the diagnostic value of serum MMP-9 and SAA in the diagnosis of RP and sCAP. The correlation between serum MMP-9 and SAA and the patient's lung function indexes was analyzed, and the logistic single-factor and multivariate analyses were performed to analyze the factors of sCAP in esophageal cancer radiotherapy.

RESULTS

PaO2, FVC, and FEV1 decreased in RP and sCAP, and PaCO2, white blood cells, serum MMP-9, and SAA levels increased (P < 0.05); serum MMP-9 and SAA were negatively correlated with lung function (P < 0.05); the AUC of serum MMP-9 and SAA in RP was 0.833 and 0.823, respectively, and the AUC of the two combined diagnosis of RP was 0.919. The AUC of serum MMP-9 and SAA in sCAP was 0.809 and 0.797, respectively, and the AUC of both combined diagnosis of sCAP was 0.873; logistics multivariate analysis found that serum MMP-9, serum SAA, double lung V5, and V20 were independent risk factors for sCAP caused by radiotherapy for esophageal cancer (P < 0.05).

CONCLUSION

Serum MMP-9 and SAA increase in RP and sCAP and are negatively correlated with lung function in patients with pneumonia. They are independent risk factors for severe pneumonia caused by radiotherapy of esophageal cancer and have good diagnostic value.

Traditional Chinese medicine and lung cancer--From theory to practice

With the continuous breakthroughs in molecular biology and biochemistry, we have constantly made great progress in the treatment of lung cancer. There is no doubt that standard treatment (such as surgery, radiotherapy, chemotherapy, targeted therapy, and immunotherapy) has greatly improved the prognosis of lung cancer populations. In particular, the immunotherapy has brought more and more good news to countless lung cancer patients. In contrast to these standard treatments, traditional Chinese medicine (TCM) rarely has a profound and comprehensive overview in the field of lung cancer. This article will summarize the latest progress of TCM in lung cancer which is mainly non-small cell lung cancer (NSCLC) from theory to clinical practice, which would carry forward the sophisticated TCM and promote the development of modern medicine.
