RESUMO
ObjectiveTo compare the efficacy and safety of acupuncture combined with auricular acupoints patches and nicotine transdermal patch in treating moderate to severe nicotine dependence. MethodsIn a rando-mized controlled trial, 64 quit smoking voluntary subjects with moderate to severe nicotine dependence were randomly divided at a ratio of 1∶1 into a treatment group and a control group, with 32 cases in each group. The treatment group was given acupuncture combined with auricular acupoints patches, twice weekly, four weeks as a course for two courses. The control group was given nicotine transdermal patch, one patch per day for 24 hours, 8 weeks. The cure rate was assessed after treatment and at follow-up (the 16th week after treatment).The daily smoking volume, exhaled carbon monoxide (CO) value, Nicotine Dependence Scale (FTND), Minnesota Nicotine Withdrawal Symptoms Scale (MNWS), and Pittsburgh Sleepiness Index Inventory (PSQI) were evaluated before and after treatment and at follow-up, and adverse effects were recorded. ResultsIn terms of the cure rate, there were both six cured cases (20%) after treatment and at follow-up in the treatment group, while in the control group, seven (23.3%) and five (16.7%) patients were cured after treatment and at follow-up, respectively, with no statistically significant differences between the two groups both after treatment and at follow-up (P>0.05). The daily smoking volume and exhaled CO value significantly decreased after treatment and at follow-up in both groups (P<0.05), but were not significantly different between the groups after treatment and at follow-up (P>0.05). After treatment and at follow-up, FTND, MNWS, and PSQI scores were significantly reduced in both groups compared with those before treatment (P<0.05). There was no statistically significant difference in the FTND scale scores between the two groups after treatment and at follow-up (P>0.05), while the MNWS and PSQI scale scores were lower in the treatment group than in the control group (P<0.05). ConclusionAcupuncture combined with auricular acupoint patches for moderate to severe nicotine dependence has comparable effect with the first-line drug nicotine patch in terms of increasing the cure rate and decreasing the degree of nicotine dependence, and is superior to nicotine patch in terms of relieving withdrawal symptoms and improving sleep, with stable long-term effect.
RESUMO
Objective To compare the dosimetric differences of four fluence smoothing (FS) levels of the Monaco system in intensity-modulated radiation therapy (IMRT) after rectal cancer surgery, and to provide a reference for FS selection in clinical practice. Methods A total of 15 postoperative patients with rectal cancer admitted in 2020 were selected. Under the same optimal conditions, FS was set to Off, Low, Medium, and High for IMRT planning. The data were analyzed by SPSS 20.0 software. The dosimetric parameters of planning target volume and organs at risk (OARs), the number of Segments, the number of monitor units (MUs), the estimated total delivery time (ETDT), and the gamma pass rate were compared between the four FS levels. Results The four FS levels resulted in clinically acceptable dosimetric parameters of the planning target volume and OARs, and there was no significant difference in dose distribution between FS levels. From FS-Off to FS-High, number of Segments, number of Mus, and ETDT decreased by 15.2%, 11.8%, and 6.7%, respectively, whereas gamma pass rate increased by 1.6%. Conclusion The IMRT plans at four FS levels can meet the clinical requirements. Considering the planning quality and execution efficiency, FS-High is recommended for postoperative IMRT of patients with rectal cancer.
RESUMO
Background: This study aimed to identify frontiers for further studies via brief understanding in complementary and alternative medicine (CAM) for substance use disorders (SUDs). Materials and Methods: Publications on the use of CAM for treating SUDs were retrieved from the Web of Science Core Collection from 2001 to 2020 on July 12, 2020, and visualized by CiteSpace V. Results: A total of 3,807 publications were obtained. The USA, China, and England were the leading research centers. However, India and Pakistan have recently focused on assessing CAM for the treatment of SUDs. Frederick L Altice was found to be the most productive author. Addiction ranked first among the frequently cited journals, which exceeded 1,000. The most common CAM therapies were acupuncture and CAM psychotherapies, such as mindfulness meditation. Conclusion: CAM is gaining attention globally for treating SUDs. CAM psychotherapy and acupuncture are hotspots and deserve further study. Researchers should strengthen peer cooperation in this field.
RESUMO
BACKGROUND: Acupuncture is widely used for infertile women without undergoing assisted reproductive techniques (ART) in China but its effect is unclear. We aim to assess whether acupuncture and its combined therapy exert a positive influence on the outcome of female fertility. METHODS: We searched 6 databases, including Medline, EMBASE, the Cochrane Central Register of Controlled Trials, the China National Knowledge Infrastructure (CNKI), the China Science and Technology Journal Database (VIP), and Wan-Fang Data, from inception to June 2018. Studies of randomized controlled trials (RCTs) on women with infertility treated by acupuncture or its combined therapy were included. A meta-analysis was performed using Revman 5.3. The methodological quality of the studies was assessed through the risk of bias assessment tool by the Cochrane Collaboration. RESULTS: The pregnancy rate was significantly improved with treatment (RRâ=â1.84, 95% CI 1.62 to 2.10, Pâ<â.00001), compared to that in the control group. Subgroup analysis showed that comparing with pure western medicine intervention, no matter intervention with acupuncture alone, with acupuncture plus western medicine, with acupuncture plus Chinese medicine, or acupuncture plus Chinese medicine and western medicine, all of these subgroups exhibited significant improvement. The subgroup according to different types of infertility showed a significant improvement in infertility caused by polycystic ovary syndrome, tubal infertility, ovulatory disorder, and other factors. In addition, the ovulation rate and endometrial thickness were significantly increased. The level of LH was obviously decreased. Moreover, with acupuncture, less adverse effects occurred. The funnel plot revealed that publication bias might exist. All trials included had unclear risks in the aspects of allocation concealment, blinding of participants and personnel, blinding of outcome assessment, selective reporting, and other bias. Only 1 study was assessed as unclear risk in random sequence generation. In the incomplete outcome data, all studies were low risk, except 1. CONCLUSIONS: Acupuncture and its combined therapy may be effective for treating female infertility. However, the included studies are not robust enough to draw a firm conclusion due to the not robustly sampled quality of the included studies. Future high-quality RCTs are needed to confirm our findings.

RESUMO
Objective To investigate the effect of berberine anti macrophages apoptosis, initially to determine the concentration of anti-apoptosis and to explore its mechanisms of treatment in atherosclerosis (AS). Methods Apoptosis of RAW264.7 macrophages is induced by 0.5 μmol/L Tg and 50 μg/ml Fuc. The cell survival rate and apoptosis rate was detected by MIT and flow cytometry, respectively. Results There was statistical significance between the berberine group of 800 μg/ml and normal group in the cell sur-vival rate(P<0.01). With the decline in concentration of berberine, the cell apoptosis rate showed a down-ward trend, berberine (0.02-0.63 μg/ml) effectively inhibited the cell apoptosis induced by Tg and Fuc. Conclusion Berberine group has little impact on the cell proliferation. Berberine can effectively inhibit the cell apoptosis induced by Tg and Fuc.
RESUMO
Non-vascular interventional diagnostic methods of thyroid nodules include ultrasonography-guided fine-needle aspiration cytology(USgFNAC)and ultrasonography-guided core-needle biopsy(USgCNB).USgFNAC is a practical method used to select and to guide the treatment of various thyroid nodules, however, it is difficult to make a differentiation between benign and malignant lesions simply to rely on the findings of a small number of cells.USgCNB has the advantage of being able to obtain satisfactory specimen enough for making a histological diagnosis, although this procedure is contraindicated in some patients.Non-vascular interventional treatments of thyroid nodules include percutaneous ethanol injection(PEI) and ultrasonography-guided interstitial laser photocoagulation(USgILP).Both PEI and USgILP have fine effect on the benign thyroid nodules.Compared with PEI, laser-induced necrosis can be well controlled, thus, the adverse reactions, such as the formation of fibrosis adjacent to the nodule, vocal cord paralysis, etc.can be avoided.Non-vascular interventional treatments may cause some untoward effects.For the diagnosis and treatment of thyroid nodules, the non-vascular interventional procedure is simple, safe, effective and economic with less complications, therefore, this technique is worth being popularized in clinical practice.
RESUMO
Aim To investigate the change in neuropeptide Y(NPY) Y1 receptor level in infarcted myocardium tissues of (MI) rats. Method MI was induced by ligating the left descending anterior coronary artery (LAD) in the heart of rats. The techniques of reverse transcription polymerase chain reaction (RT-PCR) were used to identify the exist of NPY Y1 receptor mRNA in myocardial tissues. The technique of semi-quantitative PCR wa s used to observe the change of NPY Y1 receptor mRNA level. Results NPY Y1 receptor mRNA distributed in the heart tissues of rat. Compared with sham operated rats ,the NPY Y1 receptor mRNA level both in infarction area and non-infarction area was increased significantly after MI fo r 1d and 3d. The NPY Y1 receptor mRNA level in the heart tissues of sham-op erated rats was also significantly increased compared with that in control rats . Conclusion These results suggest that MI may result in increase NPY Y1 receptor level in the heart tissues of rats. Stre ss stimulation such as surgery may also increase the NPY Y1 receptor level in the heart.

RESUMO
Objective: To study the relationship between vitamin A (VA) supplementation and the level of IgG antibody to measles strengthened vaccination. Method: Fifty-three school children aged 5-13 years were selected as the test group of VA supplementation, and fifty-two school children as the control group whose ages and sex matched with the test group. The test group was supplicd po the VA pills (2 500IU) at the same time with measles strengthened vaccination for one month. The level of serum VA was analyzed by HPLC. Measles antibody IgG was detected by ELISA. Results: One month after VA supplementation, sernm VA in test group was 376.5?74.2 ?g/L, showing statistical increase over before. The positive rates of measles antibody in the test group were increased from 69.8% to 100%, and the protective rate from 5.6% to 60.4%. The positive rates of measles antibody in the control group were increased from 71.2% to 100%, and the protective rates from 0% to 17.4%. The protective rate in the test group was statistically higher than the control. Conclusion: Simultaneous VA supplementation (especially for the children of VA deficiency) and measles strengthened vaccination contribute to the increase of measles antibody IgG in school children.
