RESUMO

Exposure to pesticides induces oxidative stress and deleterious effects on various tissues in non-target organisms. Numerous models investigating pesticide exposure have demonstrated metabolic disturbances such as imbalances in amino acid levels within the organism. One potentially effective strategy to mitigate pesticide toxicity involves dietary intervention by supplementing exogenous amino acids and their derivates to augment the body's antioxidant capacity and mitigate pesticide-induced oxidative harm, whose mechanism including bolstering glutathione synthesis, regulating arginine-NO metabolism, mitochondria-related oxidative stress, and the open of ion channels, as well as enhancing intestinal microecology. Enhancing glutathione synthesis through supplementation of substrates N-acetylcysteine and glycine is regarded as a potent mechanism to achieve this. Selection of appropriate amino acids or their derivates for supplementation, and determining an appropriate dosage, are of the utmost importance for effective mitigation of pesticide-induced oxidative harm. More experimentation is required that involves large population samples to validate the efficacy of dietary intervention strategies, as well as to determine the effects of amino acids and their derivates on long-term and low-dose pesticide exposure. This review provides insights to guide future research aimed at preventing and alleviating pesticide toxicity through dietary intervention of amino acids and their derivates.

RESUMO

Tumor microenvironment (TME)-responsive size-changeable and biodegradable nanoplatforms for multimodal therapy possess huge advantages in anti-tumor therapy. Hence, we developed a hyaluronic acid (HA) modified CuS/MnO2 nanosheets (HCMNs) as a multifunctional nanoplatform for synergistic chemodynamic therapy (CDT)/photothermal therapy (PTT)/photodynamic therapy (PDT). The prepared HCMNs exhibited significant NIR light absorption and photothermal conversion efficiency because of the densely deposited ultra-small sized CuS nanoparticles on the surface of MnO2 nanosheet. They could precisely target the tumor cells and rapidly decomposed into small sized nanostructures in the TME, and then efficiently promote intracellular ROS generation through a series of cascade reactions. Moreover, the local temperature elevation induced by photothermal effect also promote the PDT based on CuS nanoparticles and the Fenton-like reaction of Mn2+, thereby enhancing the therapeutic efficiency. Furthermore, the T1-weighted magnetic resonance (MR) imaging was significantly enhanced by the abundant Mn2+ ions from the decomposition process of HCMNs. In addition, the CDT/PTT/PDT synergistic therapy using a single NIR light source exhibited considerable anti-tumor effect via in vitro cell test. Therefore, the developed HCMNs will provide great potential for MR imaging and multimodal synergistic cancer therapy.

RESUMO

This study aims to systematically review the efficacy and safety of Shufeng Jiedu Capsules in the treatment of influenza. The randomized controlled trial(RCT) of Shufeng Jiedu Capsules alone or in combination with conventional western medicine for treating influenza were retrieved from PubMed, EMbase, Cochrane Library, Web of Science, SinoMed, CNKI, VIP, Wanfang, and ClinicalTrails.gov. The data analysis was performed in RevMan 5.4.1. The Cochrane risk of bias assessment tool was used to evaluate the quality of the involved RCT, and GRADEpro GDT to assess the quality of the evidence. A total of 11 RCTs involving 1 836 patients were included in this study. Compared with conventional western medicine, Shufeng Jiedu Capsules/Shufeng Jiedu Capsules + conventional western medicine improved the response rate(RR=1.09, 95%CI[1.03, 1.15], P=0.002), shortened the time to relief of cough, and increased the 3-day sore throat relief rate, whereas there was no significant difference in the time to fever abatement, the time to relief of sore throat, 3-day cough relief rate, or 3-day runny nose relief rate. Subgroup-analysis showed that Shufeng Jiedu Capsules + conventional western medicine improved the response rate(RR=1.11, 95%CI[1.08, 1.15], P<0.000 01), shortened the time to relief of cough, and increased the 3-day relief rate of symptoms(cough, sore throat, and runny nose) compared with conventional western medicine alone, while there was no significant difference in the time to fever abatement or the time to relief of sore throat. Shufeng Jiedu Capsules alone could not improve the response rate(RR=0.97, 95%CI[0.93, 1.02], P=0.19). In addition, Shufeng Jiedu Capsules/Shufeng Jiedu Capsules + conventional western medicine vs conventional western medicine were no significant difference in adverse reactions(RR=0.98, 95%CI[0.57, 1.69], P=0.95). The available evidence suggests that Shufeng Jiedu Capsules is effective and safe in the treatment of influenza, and the combination of Shufeng Jiedu Capsules with conventional western medicine can accelerate the relief of symptoms. However, since the number and quality of the included studies were low, the above findings remained to be further verified by multicenter RCT with large sample sizes.

RESUMO

OBJECTIVES: To observe the therapeutic effect of electroacupuncture (EA) on neurogenic urinary retention rats, so as to explore the underlying mechanism of EA in treating neurogenic urinary retention by focusing on 3-phosphoinositide-dependent protein kinase 1 (PDK1)/protein kinase B (Akt)/hyperpolarization activated cyclic nucleotide-gated cation channel 4 (HCN4) pathway. METHODS: Female SD rats were randomly divided into sham operation, model, EA, PDK1 inhibitor, HCN4 blocker and EA + HCN4 blocker groups, with 20 rats in each group. The model of sacral spinal cord injury was established by modified Hassan Shaker spinal cord transection method. EA (2 Hz/15 Hz, 0.5 mA) was applied to "Zhongji" (CV3) and "Zhongliao" (BL33) for 20 min, once daily for 10 days. Rats of the PDK1 inhibitor group received intraperitoneal injection of OSU-03012 (20 mg/kg), and rats of the HCN4 blocker group received intraperitoneal injection of ivabradine (10 mg/kg), both once every other day for 10 days. The urodynamic indexes of rats were detected by multi-channel physiological recorder;muscle strip test was used to detect detrusor excitability;the morphological changes of bladder were observed by HE staining. Immunofluorescence double staining was used to detect the co-expression of HCN4 and C-Kit, a specific marker of interstitial cells of Cajal in bladder. Western blot was used to detect the expression of PDK1/Akt/HCN4 pathway proteins in bladder tissue and heat shock protein 27 (HSP27), a protein related to bladder contraction function. RESULTS: Compared with the sham operation group, the rats in the model group showed urinary dysfunction, decreased leak point pressure, isolated detrusor spontaneous contraction frequency, fluorescence intensity of C-Kit positive cells, HCN4+/C-Kit+ co-expression, HCN4 and p-HSP27/HSP27 protein expression in bladder tissue (P<0.05), and increased maximum bladder capacity and comp-liance, minimum tension during contraction of isolated detrusor, PDK1 and p-Akt/Akt protein expression in bladder tissue (P<0.05). Meanwhile, the above index were all reversed after EA and PDK1 inhibitor intervention (P<0.05). In comparison with the EA group, the rats had severe urinary dysfunction, the urine leakage point pressure, spontaneous contraction frequency, fluorescence intensity of C-Kit positive cells, the co-expression of HCN4+/C-Kit+, and the protein expression of HCN4 and p-HSP27/HSP27 were decreased (P<0.05), the maximum bladder capacity and compliance, the minimum tension during contraction of isolated detrusor, and the protein expression of PDK1 and p-Akt/Akt in bladder tissue were increased (P<0.05) in both HCN4 blocker and EA+HCN4 blocker groups. HE staining showed exfoliated bladder epithelium and disordered layers, vacuolization of bladder wall cells, with infiltration of neutrophils in mucosal and muscular layers in the model group, which were relatively milder in the EA and PDK1 inhibitor groups, but worse in the HCN4 blocker and EA + HCN4 blocker groups. CONCLUSIONS: EA can improve the urinary dysfunction in rats with neurogenic urinary retention, which may be related to its effect in inhibiting the activation of PDK1/Akt pathway, promo-ting HCN4-mediated detrusor excitatory contraction and urinary electrical signal activation.

RESUMO

Mining data from traditional Chinese medicine(TCM) prescriptions is one of the important methods for inheriting the experience of famous doctors and developing new drugs. However, current research work has problems such as to be optimized research plans and non-standard statistics. The main problems and corresponding solutions summarized by the research mainly include four aspects.(1)The research plan design needs to consider the efficacy and quality of individual cases.(2)The significance of the difference in confidence order of association rules needs to be further considered, and the lift should not be ignored.(3)The clustering analysis steps are complex. The selection of clustering variables should comprehensively consider factors such as the frequency of TCM, network topology parameters, and practical application significance. The selection of distance calculation and clustering methods should be improved based on the characteristics of TCM clinical data. Jaccard distance and its improvement plan should be given attention in the future. A single, unexplained clustering result should not be presented, but the final clustering plan should be selected based on a comprehensive consideration of TCM clinical characteristics and objective evaluation indicators for clustering.(4)When calculating correlation coefficients, algorithms that are only suitable for continuous variables should not be applied to binary variables. This article explained the connotations of the above problems based on the characteristics of TCM clinical research and statistical principles and proposed corresponding suggestions to provide important references for future data mining research work.

RESUMO

In observational studies, herbal prescriptions are usually studied in the form of "similar prescriptions". At present, the classification of prescriptions is mainly based on clinical experience judgment, but there are some problems in manual judgment, such as lack of unified criteria, labor consumption, and difficulty in verification. In the construction of a database of integrated traditional Chinese and western medicine for the treatment of coronavirus disease 2019(COVID-19), our research group tried to classify real-world herbal prescriptions using a similarity matching algorithm. The main steps include 78 target prescriptions are determined in advance; four levels of importance labeling shall be carried out for the drugs of each target prescription; the combination, format conversion, and standardization of drug names of the prescriptions to be identified in the herbal medicine database; calculate the similarity between the prescriptions to be identified and each target prescription one by one; prescription discrimination is performed based on the preset criteria; remove the name of the prescriptions with "large prescriptions cover the small". Through the similarity matching algorithm, 87.49% of the real prescriptions in the herbal medicine database of this study can be identified, which preliminarily proves that this method can complete the classification of herbal prescriptions. However, this method does not consider the influence of herbal dosage on the results, and there is no recognized standard for the weight of drug importance and criteria, so there are some limitations, which need to be further explored and improved in future research.

RESUMO

This study aims to explore the efficacy and safety of Lianhua Qingwen preparations combined with Oseltamivir in the treatment of influenza patients. PubMed, Cochrane Library, EMbase, SinoMed, CNKI, Wanfang, and VIP were searched for the randomized controlled trials(RCTs) involving the comparison between the influenza patients treated with Lianhua Qingwen preparations combined with Oseltamivir and those treated with Oseltamivir alone. Fever clearance time was taken as the primary outcome indicator. Clinical effective rate(markedly effective and effective), time to muscle pain relief, time to sore throat relief, time to cough relief, time to nasal congestion and runny nose relief, time to negative result of viral nucleic acid test, and adverse reactions were taken as the secondary outcome indicators. The data were extracted based on the outcome indicators and then combined. The Cochrane collaboration's tool for assessing risk of bias was used to evaluate the quality of a single RCT, and the grading of recommendations assessment, development and evaluations(GRADE) system to assess the quality of a single outcome indicator. RevMan 5.3 was employed to analyze data and test heterogeneity. Finally, 16 RCTs involving 1 629 patients were included for analysis. The Meta-analysis showed that Lianhua Qingwen preparations combined with Oseltamivir was superior to Oseltamivir alone in the treatment of influenza in terms of clinical effective rate(RR=1.16, 95%CI [1.12, 1.20], P<0.000 01), fever clearance time(SMD=-2.02, 95%CI [-2.62,-1.41], P<0.000 01), time to muscle pain relief(SMD=-2.50, 95%CI [-3.84,-1.16], P=0.000 2), time to sore throat relief(SMD=-1.40, 95%CI [-1.93,-0.85], P<0.000 01), time to cough relief(SMD=-1.81, 95%CI [-2.44,-1.19], P<0.000 01), time to nasal congestion and runny nose(SMD=-2.31, 95%CI [-3.61,-1.01], P=0.000 5), and time to negative result of viral nucleic acid test(SMD=-0.68, 95%CI [-1.19,-0.16], P=0.01). However, due to the low quality of the trials, the above conclusions need to be proved by more high-quality clinical studies. In addition, we still need to attach importance to the adverse reactions of the integrated application of Chinese and western medicines.

RESUMO

OBJECTIVE: To perform a systematic review to assess the effectiveness and safety of Reduning Injection versus neuraminidase inhibitors in treatment of influenza. METHODS: The MEDLINE, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), Chinese Bio-medical Literature and Retrieval System (Sinomed), China National Knowledge Infrastructure Database (CNKI), China Science and Technology Journal Database (VIP), Wanfang Data Knowledge Service Platform and ClinicalTrails.gov were systematically searched from inception dates to May 2021 for randomized controlled trials (RCTs) exploring Reduning Injection alone or in combination with neuraminidase inhibitors in patients with influenza. Statistical analysis was performed using RevMan 5.4 and Stata 15.1. The qualities of the involved studies were assessed by the risk of bias according to the Cochrane handbook. The evidence quality of each outcome was evaluated by GRADEpro GDT. RESULTS: Twelve trials with 1,460 patients were included. The included studies had a certain unclear or high risk of bias. Reduning Injection appeared to be more effective in shortening the fever clearance time (MD: -16.20 h, 95% CI: -19.40 to -12.99, 7 trials, 814 patients, I2=94%, very low certainty), fever alleviation time (MD: -4.09 h, 95% CI: -4.22 to -3.96, 3 trials, 366 patients, I2=0%, low certainty), cough alleviation time (MD: -21.34 h, 95% CI: -41.56 to -1.11, 2 trials, 228 patients, I2=89%, very low certainty), fatigue alleviation time (MD: -31.83 h, 95% CI: -36.88 to -26.77, 2 trials, 270 patients, I2=0%, low certainty), sore throat alleviation time (MD: -28.66 h, 95% CI: -32.23 to -25.10, 1 trial, 150 patients, low certainty), and improving the total effective rate (RR: 1.15, 95% CI: 1.06 to 1.25, 10 trials, 1,074 patients, I2=76%, very low certainty). Besides, Reduning Injection seemed generally safe. CONCLUSIONS: This study provided low or very low evidence indicating Reduning Injection may be effective in the treatment of influenza and might be safe. Further rigorously designed studies are needed to confirm the effectiveness and safety of Reduning Injection and support it as a recommendation for influenza.

RESUMO

BACKGROUND: To assess the effectiveness and safety of moxibustion for post-stroke depression (PSD). METHODS: A search was conducted in the following English and Chinese databases: Medline, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature (CBM), VIP and Wanfang. The outcomes included Hamilton Depression Rating Scale (HAMD), effective rate, and Modified Edinburgh-Scandinavian Stroke Scale (MESSS) scale. The formulation of search strategy, data extraction, and quality evaluation of involved studies was performed according to Cochrane handbook guidelines. The software RevMan 5.4 and Stata 16 were used for data analysis. The evidence quality of each outcome was evaluated by GRADEpro guideline development tool (GDT). RESULTS: A total of 14 trials with 863 participants were included. A certain risk of bias of unclear or high was detected in the included studies. Compared with the control group, adding moxibustion could change the value of HAMD [standardized mean difference (SMD) =-1.17; 95% confidence interval (CI): -1.55 to -0.79; I2=85.5%; P<0.01] and the effective rate [risk ratio (RR) =1.22; 95% CI: 1.13 to 1.32; I2=0.0%; P=0.56], and the differences in the MESSS scale (SMD =-0.72; 95% CI: -1.06 to -0.38; I2=0.0%; P=0.80) had statistical differences. The certainty was low in effective rate, and very low in HAMD and MESSS. Besides, moxibustion was shown to be generally safe. DISCUSSION: This review found that moxibustion may be an effective intervention for PSD. However, the results of this study have a certain limitation. The benefits of moxibustion for PSD need to be confirmed in the future by more high-quality randomized controlled trials (RCTs).

RESUMO

The present study explored the effect of co-amorphous technology in improving the dissolution rate and stability of silybin based on the puerarin-silybin co-amorphous system prepared by the spray-drying method. Solid-state characterization was carried out by powder X-ray diffraction(PXRD), polarizing microscopy(PLM), Fourier transform infrared spectroscopy(FT-IR), differential scanning calorimetry(DSC), etc. Saturated powder dissolution, intrinsic dissolution rate, moisture absorption, and stability were further investigated. The results showed that puerarin and silybin formed a co-amorphous system at a single glass transition temperature which was higher than that of any crude drug. The intrinsic dissolution rate and supersaturated powder dissolution of silybin in the co-amorphous system were higher than those of the crude drug and amorphous system. The co-amorphous system kept stable for as long as three months under the condition of 40 ℃, 75% relative humidity, which was longer than that of the single amorphous silybin. Therefore, the co-amorphous technology could significantly improve the dissolution and stability of silybin.

RESUMO

Since narrative medicine was introduced in China, it has been widely used in medical education and clinical practice. The research on narrative medicine in China is especially characterized by its combination with traditional Chinese medicine(TCM). At present, the research on narrative medicine in China is still in the stage of small-scale practicing and theory advocating. Besides, there is also a lack of guidance on experimental design methodology for clinical application, which leads to few high-quality studies in this field. The present study reviewed the current high-quality research on narrative medicine to discuss the value and prospects of mixed methods research in narrative medicine. In addition, the common design, application procedures, and notes of mixed methods research were explained to provide references for the extensive applications of narrative medicine in the medical field, especially TCM clinical practice, education, and scientific research.

RESUMO

The objective of this study was to identify the decussating dentato-rubro-thalamic tract (d-DRTT) and its afferent and efferent connections in healthy humans using diffusion spectrum imaging (DSI) techniques. In the present study, the trajectory and lateralization of the d-DRTT was explored using data from subjects in the Massachusetts General Hospital-Human Connectome Project adult diffusion dataset. The afferent and efferent networks that compose the cerebello-thalamo-cerebral pathways were also reconstructed. Correlation analysis was performed to identify interrelationships between subdivisions of the cerebello-dentato-rubro-thalamic and thalamo-cerebral connections. The d-DRTT was visualized bilaterally in 28 subjects. According to a normalized quantitative anisotropy and lateralization index evaluation, the left and right d-DRTT were relatively symmetric. Afferent regions were found mainly in the posterior cerebellum, especially the entire lobule VII (crus I, II and VIIb). Efferent fibers mainly are projected to the contralateral frontal cortex, including the motor and nonmotor regions. Correlations between cerebello-thalamic connections and thalamo-cerebral connections were positive, including the lobule VIIa (crus I and II) to the medial prefrontal cortex (MPFC) and the dorsolateral prefrontal cortex and lobules VI, VIIb, VIII, and IX, to the MPFC and motor and premotor areas. These results provide DSI-based tratographic evidence showing segregated and parallel cerebellar outputs to cerebral regions. The posterior cerebellum may play an important role in supporting and handling cognitive activities through d-DRTT. Future studies will allow for a more comprehensive understanding of cerebello-cerebral connections.

RESUMO

We analyzed the biological activity and composition of total triterpenoids extracted from the liquid fermentation culture of the medicinal mushroom Sanghuangporus sanghuang. S. sanghuang total triterpenoid extract (STTE) had the strongest inhibitory effect on Staphylococcus aureus, and STTE at 2-fold the minimum inhibitory concentration had a significant effect on the growth of four types of bacteria and caused marked nucleic acid leakage. Scanning electron microscopy confirmed that STTE destroyed bacterial cell walls. STTE also significantly inhibited the proliferation of Caco-2 cells and disrupted their morphology. Flow cytometry revealed that STTE induced cell cycle arrest and induced early and late apoptosis of Caco-2 cells. Infrared spectroscopy, and gas chromatography-mass spectrometry resulted in the detection of a variety of triterpenoids (e.g., pentacyclic triterpenoid, lanolinane triterpenoid, and trans-squalene) as well as other small molecules (e.g., esters, acids, and aldehydes). Our findings indicate that STTE has antibacterial and antitumor activity and will enable screening of novel fungal-derived anticancer and antibacterial compounds.

RESUMO

INTRODUCTION: In this report, we aim to describe the design for the randomised controlled trial of Stereotactic electroencephalogram (EEG)-guided Radiofrequency Thermocoagulation versus Anterior Temporal Lobectomy for Mesial Temporal Lobe Epilepsy with Hippocampal Sclerosis (STARTS). Mesial temporal lobe epilepsy (mTLE) is a classical subtype of temporal lobe epilepsy that often requires surgical intervention. Although anterior temporal lobectomy (ATL) remains the most popular treatment for mTLE, accumulating evidence has indicated that ATL can cause tetartanopia and memory impairments. Stereotactic EEG (SEEG)-guided radiofrequency thermocoagulation (RF-TC) is a non-invasive alternative associated with lower seizure freedom but greater preservation of neurological function. In the present study, we aim to compare the safety and efficacy of SEEG-guided RF-TC and classical ATL in the treatment of mTLE. METHODS AND ANALYSIS: STARTS is a single-centre, two-arm, randomised controlled, parallel-group clinical trial. The study includes patients with typical mTLE over the age of 14 who have drug-resistant seizures for at least 2 years and have been determined via detailed evaluation to be surgical candidates prior to randomisation. The primary outcome measure is the cognitive function at the 1-year follow-up after treatment. Seizure outcomes, visual field abnormalities after surgery, quality of life, ancillary outcomes, and adverse events will also be evaluated at 1-year follow-up as secondary outcomes. DISCUSSION: SEEG-guided RF-TC for mTLE remains a controversial seizure outcome but has the advantage for cognitive and visual field protection. This is the first RCT studying cognitive outcomes and treatment results between SEEG-guided RF-TC and standard ATL for mTLE with hippocampal sclerosis. This study may provide higher levels of clinical evidence for the treatment of mTLE. TRIAL REGISTRATION: ClinicalTrials.gov NCT03941613 . Registered on May 8, 2019. The STARTS protocol has been registered on the US National Institutes of Health. The status of the STARTS was recruiting and the estimated study completion date was December 31, 2021.

RESUMO

Antiviral Oral Liquid is modified on the basis of Baihu Decoction in Treatise on Febrility Diseases by ZHANG Zhongjing and Qingwen Baidu Yin in Qing Dynasty, with effects in clearing toxic heat, repelling dampness and cooling blood. It is widely used in clinical treatment of common colds, influenza and upper respiratory tract infection, mumps, viral conjunctivitis and hand-foot-mouth disease, with a good clinical efficacy and safety. Based on a questionnaire survey of clinicians and a systematic review of study literatures on Antiviral Oral Liquid, the international clinical practice guidelines development method was adopted to analyze the optimal available evidences and expert experiences in the "evidence-based, consensus-based and experience-based" principles. The consensus was jointly reached by more than 30 multidisciplinary experts nationwide, including clinical experts of traditional Chinese and Western medicine in the field of respiratory diseases and infectious diseases, and methodological experts. In the study, literatures were retrieved based on clinical problems in the clinical survey as well as PICO clinical problems. The GRADE system was used for the classification and evaluation of evidence, and fully combined with clinical expert experience, so as to reach expert consensus by the nominal grouping method.

RESUMO

To sort out the key points in "PICOS" design of clinical trial scheme for influenza, and optimize the clinical trial scheme of Chinese patent medicine in the treatment of influenza by strictly following the principle of evidence-based medicine, focusing on the clinical practice of the disease, and highlighting the characteristics of traditional Chinese medicine. "The design of a randomized, double-blind, positive parallel control study of a certain herbal preparation for the treatment of non-severe influenza" was taken as an example in this study, and the key points in the clinical trial design of Chinese patent medicine for the treatment of influenza were specifically discussed from six aspects, including the type of study, object of study, intervention measures, control measures, outcome indicators and frequently asked questions in test design. From methodological suggestions, in the design scheme of clinical trial on efficacy and safety of Chinese patent medicine in the treatment of influenza, the randomized controlled study should be the first choice for type of study; the inclusion criteria should define both the diagnostic criteria of Western medicine and the syndromes of traditional Chinese medicine(TCM); the exclusion criteria should include a comprehensive list of confounding factors and special circumstances lea-ding to bias in the study results; the interventions should be based on a well-defined dosing programme; internationally recognized positive drugs or guidelines should be used as control measures, with median antipyretic time as the main outcome indicator. For the evalua-tion of curative effect, disease symptom scale can be set, and the TCM syndrome scoring scale was carefully used in this study, with time nodes set for the efficacy evaluation standard. The full name of the drugs should be written in the regulations on combined drug use and prohibited drug use.

RESUMO

OBJECTIVE: To conduct a pilot trial to explore the effectiveness and safety of moxibustion robots in treating primary dysmenorrhea (PD) and evaluate its feasibility in clinic. METHODS: A total of 70 participants with PD were allocated to either moxibustion robot (MR) group (35 cases) or manual moxibustion (MM) group (35 cases) using computer-generated randomization. One acupoint Guanyuan (CV 4) was selected to receive moxa heat stimulation. Two groups of participants were given 3 menstrual cycles of MM and MR treatment respectively (once a day, 5 days a session) and received another 3 menstrual cycles follow-up. The degree of pain was evaluated by short-form McGill pain questionnaire (SF-MPQ) and the symptoms of dysmenorrhea were evaluated by Cox Menstrual Symptom Scale (CMSS). The safety was measured by the occurrence rate of adverse events (AEs), including burns (blisters, red and swollen), itching, bowel changes, menstrual cycle disorder, menorrhagia and fatigue, etc. RESULTS: A total of 62 patients completed the trial, 32 in MR group and 30 in MM group. Compared with baseline, scores of SF-MPQ and CMSS significantly decreased in both groups (P<0.05), and no significant difference was observed between the two groups in the 3rd and 6th menstrual cycles (P>0.05). The total occurrence rate of AEs in MR group was 2.1%, which was significantly lower than MM group (7.2%, P<0.05). CONCLUSIONS: MR has the same effect as MM at SF-MPQ and CMSS in patients with PD. However, MR is safer than MM (Trial registration No. ChiCTR1800018236).

RESUMO

OBJECTIVE: To investigate the protective effect of electroacupuncture (EA) at "Zusanli" (ST 36) in pregnant rats on lung dysplasia of newborn rats with intrauterine growth restriction (IUGR) induced by maternal food restriction. METHODS: Twenty-four female SD rats were randomly divided into a control group, a control+EA group, a model group and a model+EA group, 6 rats in each group. From the 10th day into pregnancy to the time of delivery, the rats in the model group and the model+EA group were given with 50% dietary restriction to prepare IUGR model. From the 10th day into pregnancy to the time of delivery, the rats in the control+EA group and the model+EA group were treated with EA at bilateral "Zusanli" (ST 36), once a day. The body weight of offspring rats was measured at birth, and the body weight and lung weight of offspring rats were measured on the 21st day after birth. The lung function was measured by small animal lung function detection system; the lung tissue morphology was observed by HE staining; the content of peroxisome proliferator activated receptor γ (PPARγ) in lung tissue was detected by ELISA. RESULTS: Compared with the control group, the body weight at birth as well as the body weight, lung weight, lung dynamic compliance (Cdyn) and PPARγ at 21 days after birth in the model group were significantly decreased (P<0.01), and the peak inspiratory flow (PIF) and inspiratory resistance (RI) were significantly increased (P<0.01); the number of alveoli was significantly decreased, and the alveolar area and alveolar septal thickness were significantly increased, and some alveoli were ruptured and fused. Compared with the model group, the body weight at birth as well as the body weight, lung weight, Cdyn and PPARγ at 21 days after birth in the model+EA group were significantly increased (P<0.01, P<0.05), and the PIF and RI were significantly reduced (P<0.05); the number of alveoli was significantly increased, and the alveolar area and alveolar septal thickness were significantly reduced, and the rupture and fusion of alveolar was improved. CONCLUSION: EA at "Zusanli" (ST 36) may protect the lung function and lung histomorphology changes by regulating the level of PPARγ of lung in IUGR rats induced by maternal food restriction.

RESUMO

In view of the limitations of the existing moxibustion instruments, i.e. possible accidental injury when using moxibustion instruments, the negative effects of products from moxibustion instruments on treatment efficacy and health of medical staff and patients, a moxibustion instrument with multi-jointed manipulator is designed. This moxibustion instrument could accurately control the temperature, maintain a safe moxibustion distance, automatically process the burning ashes of moxa and selectively handle moxa smoke. The experimental results shows that this instrument could maintain the constant temperature of target acupoint, reduce the risk of empyrosis, and reasonably deal with the products of moxibustion. The purification rate of moxa smoke is 44.9%, which not only ensures the therapeutic effect of moxa smoke, but also reduces the negative effects of high-concentration moxa smoke on the health of medical staff and patients.

RESUMO

This study was to investigate the protective effect of paeoniflorin (PF) on hydrogen peroxide-induced injury. Firstly, "SMILES" of PF was searched in Pubchem and further was used for reverse molecular docking in Swiss Target Prediction database to obtain potential targets. Injury-related molecules were obtained from GeenCards database, and the predicted targets of PF for injury treatment were selected by Wayne diagram. For mechanism analysis, the protein-protein interactions were constructed by String, and the KEGG analysis was conducted in Webgestalt. Then, cell viability and cytotoxicity assay were established by CCK8 assay. Also, the experimental cells were allocated to control, model (200 µmol·L-1 H2O2), SB203580 10 µmol·L-1 (200 µmol·L-1 H2O2+ SB203580 10 µmol·L-1), PF 50 µmol·L-1 (200 µmol·L-1 H2O2+ PF 50 µmol·L-1), and PF 100 µmol·L-1 (200 µmol·L-1 H2O2+ PF 100 µmol·L-1) groups. We measured the intracellular ROS, Hoechst 33258 staining, cell apoptosis, the levels of Bcl-xl, Bcl-2, Caspase-3, Cleaved-caspase3, Cleaved-caspase7, TRPA1, TRPV1, and the phosphorylation expression of p38MAPK. There are 96 potential targets that may be associated with PF for injury treatment. Then, we chose the "Inflammatory mediator regulation of TRP channels" pathway for the experimental verification from the first 10 KEGG pathway. In experimental verification, H2O2 decreased the cell viability moderately (P < 0.05), and 100 µmol·L -1 PF increased the cell viability significantly (P < 0.05). Depending on the difference of intracellular ROS fluorescence intensity, PF inhibited H 2O2-induced reactive oxygen species production in Schwann cells. In Hoechst 33258 staining, PF reversed the condensed chromatin and apoptotic nuclei following H2O2 treatment. Moreover, Flow cytometry results showed that PF could substantially inhibit H2O2 induced apoptosis (P < 0.05). Pretreatment with PF obviously reduced the levels of Caspase3, Cleaved-caspase3, Cleaved-caspase7, TRPA1, TRPV1, and the phosphorylation expression of p38MAPK after H 2O2 treatment (P < 0.05), increased the levels of Bcl-2, and Bcl-xl ( P < 0.05). PF inhibited Schwann cell injury and apoptosis induced by hydrogen peroxide, which mechanism was linked to the inhibition of phosphorylation of p38MAPK.
