RESUMEN
There are the differences in the location of some acupoints between textbooks Meridians and Acupoints and Acupuncture and Moxibustion. Both of the textbooks are in the category of the "14th Five-Year Plan". The differences in acupoint location have brought some confusion for students, full-time teachers and researchers in the field of traditional Chinese medicine. In the paper, based on GB/T 12346-2021ï¼ Nomenclature and Location of Meridian Points, published in2021, and in reference with GB/T 12346-2006ï¼ Nomenclature and Location of Acupuncture Points, published in 2006, the discrepancy in the acupoint location was systematically collated in the aspects of the expression style and layout, text expression and potential difference of location between these two textbooks, published by China Press of Traditional Chinese Medicine, People's Medical Publishing House and China Science Publishing. Based on the historical evolution and the academic controversy of acupoint positioning, the reasons of the differences in acupoint location were analyzed, the potential influences on the teaching, examination, competition and research of Chinese medicine acupuncture were explored, and the suggestions for solution were proposed.

BACKGROUND: The analgesic effect of acupuncture is widely recognized, but the mechanical characteristics of acupuncture for pain relief, compared to non-steroidal anti-inflammatory (NSAIDs) and placebo medication, remain unknown. AIMS: To compare the modulation effects of acupuncture treatment with NSAIDs and placebo medication on descending pain modulation system (DPMS) in knee osteoarthritis (KOA) patients. METHODS: This study recruited 180 KOA patients with knee pain and 41 healthy controls (HCs). Individuals with KOA knee pain were divided randomly into groups of verum acupuncture (VA), sham acupuncture (SA), celecoxib (SC), placebo (PB), and waiting list (WT), with 36 patients in each group. VA and SA groups included ten sessions of puncturing acupoints or puncturing non-acupoints acupuncture treatment for two successive weeks. Celecoxib capsules were continuously given orally to patients in the SC group at a dosage of 200 mg daily for 2 weeks. In the PB group, patients received a placebo capsule once a day for 2 weeks at the same dosage as celecoxib capsules. In the WL group, patients did not receive any treatment. Patients underwent a resting-state BOLD-fMRI scan pre- and post-receiving the therapy, whereas HCs only underwent a baseline scan. Seed (ventrolateral periaqueductal gray, vlPAG, a key node in DPMS) based resting-state functional connectivity (rs-FC) was applied in the data analysis. RESULTS: All groups demonstrated improved knee pain scores relative to the initial state. There was no statistical difference between the VA and SA groups in all clinical outcomes, and vlPAG rs-FC alterations. KOA knee pain individuals reported higher vlPAG rs-FC in the bilateral thalamus than HCs. KOA knee pain patients in the acupuncture group (verum + sham, AG) exhibited increased vlPAG rs-FC with the right dorsolateral prefrontal cortex (DLPFC) and the right angular, which is associated with knee pain improvement. In contrast with the SC and PB group, the AG exhibited significantly increased vlPAG rs-FC with the right DLPFC and angular. Contrary to the WT group, the AG showed greater vlPAG rs-FC with the right DLPFC and precuneus. CONCLUSIONS: Acupuncture treatment, celecoxib, and placebo medication have different modulation effects on vlPAG DPMS in KOA knee pain patients. Acupuncture could modulate vlPAG rs-FC with brain regions associated with cognitive control, attention, and reappraisal for knee pain relief in KOA patients, compared with celecoxib and placebo medication.

Introduction: Acupuncture is an effective and safe therapy for patients with migraine without aura (MwoA), but only 41-59% of patients show improvement with this treatment. Screening positive responders to acupuncture treatment for MwoA can ensure that healthcare resources can be appropriately targeted to specific patients who would most benefit. The objective of this study is to determine whether the structure and functional activity in certain brain regions can predict analgesia response in patients with MwoA who receive acupuncture treatment. Methods and analysis: A total of 72 patients with MwoA and 72 healthy controls (HCs) will be enrolled in this study. Resting-state structural and functional magnetic resonance imaging (MRI) data will be collected from each participant at baseline. Patients with MwoA will undergo 12 sessions of acupuncture treatment for 8 weeks, twice per week in the first 4 weeks and once per week for the last 4 weeks. The follow-up will be 12 weeks. The number of days with migraine, frequency of migraine attacks, and average visual analog scale scores will be recorded in detail at weeks 0, 4, 8, 12, and 16 and at the end of follow-up (week 20). The positive response rate will be calculated as the proportion of patients with ≥50% reduction in the number of migraine days during follow-up compared with baseline. Machine learning methods will be applied to classify patients with MwoA and HCs and predict patients with response or non-response to acupuncture treatment based on multimodal MRI parameters, such as gray matter volume, regional homogeneity, amplitude of low-frequency fluctuation, fractional anisotropy, and mean diffusivity. Discussion: This study aims to establish brain structural and functional characteristics that can identify patients with MwoA who will derive analgesia benefits from acupuncture treatment.

RESUMEN
INTRODUCTION: Acupuncture is an efficacious and safe treatment choice for migraine prevention. Results from clinical trials have shown that non-specific effects play an important role in acupuncture's efficacy. To date, however, there is no evidence available quantitatively evaluating the effect of non-specific effects, such as patients' expectations and beliefs for acupuncturists, on acupuncture efficacy, necessitating further exploration. METHODS: A total of 156 patients with migraine without aura (MwoA) will be randomized to either junior or senior acupuncturist group, at a ratio of 1:1. The study will last 24 weeks, for each patient, comprising baseline, treatment, and follow-up phases lasting 4, 8, and 12 weeks, respectively. All patients will undergo 12 sections of acupuncture treatment delivered by either a junior or senior acupuncturist following the same acupuncture prescription and manipulation. The primary outcomes will be changes in the number of migraine days and frequency of attacks per 4 weeks cycle, relative to the baseline. Secondary outcomes will include severity of headache pain, quality of life, anxiety/depression levels, and use of non-steroidal anti-inflammatory drugs (NSAIDs) per 4 weeks cycle, compared to the baseline, as well as adverse events and rate of positive response to treatment. Prior to randomization of patients into junior or senior acupuncturist groups, the Acupuncture Expectations Evaluation Scale (AES) will be used to evaluate their expectations and belief with regards to acupuncture efficacy delivered by senior or junior acupuncturists. DISCUSSION: Results from this clinical randomized controlled trial will help to quantitatively evaluate the extent of the effect of acupuncture treatment delivered by a senior or junior acupuncturist (high relative to low expectations) in migraine patients. ETHICS AND DISSEMINATION: This trial has been approved by the Institutional Review Boards and Ethics Committees of Hospital of Chengdu University of Traditional Chinese Medicine (Approval No. 2020KL-058).
RESUMEN
There is an increasing demand for bio-based packaging materials incorporated with active nanoparticles as one of the new technologies to obtain food products with improved quality and extended shelf-life. The objectives of this study were to develop a chitosan-gelatin based edible coating incorporated with nano-encapsulated tarragon essential oils (TEO) and to investigate the effects of chitosan-gelatin coatings containing TEO or TEO-loaded nanoparticles (TEO-NPs) on the preservation of pork slices during refrigerated storage for 16 days. Nanoparticles with the average diameters of 246.27-504.60 nm were produced using different mass ratios of chitosan to TEO (1:0, 1:0.2, 1:0.4, 1:0.6, 1:0.8 and 1:1) by ionic gelation method. Zeta potential and encapsulation efficiency (EE) of the prepared TEO-NPs were 27.07-37.12 mV and 9.83-35.57%, respectively. TEO-NPs with the maximum EE were applied for preparing the edible coatings. The results suggested that the coating treatments could significantly inhibit quality deterioration of pork slices. Nano-encapsulation contributed to the sustained release of TEO and caused an improved antioxidant, antibacterial and sensory properties. The study suggests that chitosan-gelatin coating incorporated with TEO-NPs could be developed as a prospective active packaging to preserve pork slices.

The uplift of the Tibetan Plateau (TP) significantly affected both regional and global climates. Although there is evidence that the Tibetan Plateau experienced uplift during the Quaternary, the timing and amplitude are poorly constrained. However, the increased availability of long sedimentary records of vegetation change provides an opportunity to reconstruct the timing of the uplift. Here, we present a well-dated, high-resolution pollen record for the last 2.6 Ma from the Yinchuan Basin, which was incised by the Yellow River with its source in the northeastern Tibetan Plateau. Variations in the Artemisia/Chenopodiaceae (A/C) ratio of the reveal changes in moisture conditions in the Yinchuan Basin during glacial-interglacial cycles, as well as a gradual long-term aridification trend which is consistent with progressive global cooling. However, fluctuations in the percentages of Picea and Abies differ from those of the A/C ratio and we propose that they reflect changes in the vegetation and environment of high elevation areas. The Picea and Abies records reveal two phases of increased representation, at 2.1 and 1.2 Ma, which may indicate phases in the uplift of the northeastern Tibetan Plateau. Thus, they provide independent evidence for the timing of the uplift of the Tibetan Plateau during the Quaternary.

OBJECTIVE: To observe the effect of Quyu Jiedu Granules (, QJG) on the micro- microenvironment of ova in patients with endometriosis (EM). environment METHODS: Twenty EM patients who received in vitro fertilization and embryo transfer (IVF-ET) were randomized equally into a treated group and a control group. Further, 20 patients who received IVF-ET due to oviduct factors were enrolled into a non-endometriosis group. The dosage of gonadotrophic hormone used, the number of ova attained, fertilization rate and clinical pregnancy rate were all observed, and the levels of tumor necrosis factor alpha (TNF-right harpoon over left harpoon) and interleukin 6 (IL-6) in follicular fluid as well as their mRNA expressions in ovarian granular cells were detected by RT-PCR on the very day of ovum attainment. RESULTS: The ova attainment (13.80+/-6.87) and fertilization rate (0.69+/-0.31) in the treated group were all higher than the corresponding values in the control group (9.80+/-5.32 and 0.47+/-0.22); the follicular fluid contents of TNF-alpha and IL-6 in the treated group were 1.38+/-0.21 ng/mL and 130.56+/-12.81 pg/mL, respectively, which were lower than those in the control group (1.98+/-0.34 ng/mL and 146.83+/-17.65 pg/mL, respectively). Further, the treated group showed much lower mRNA expressions of TNF-alpha and IL-6 in ovarian granular cells. CONCLUSIONS: The elevation of TNF-alpha and IL-6 contents in follicular fluid and their mRNA expressions in ovarian granular cells are possibly related to the low quality of ova in EM; QJG might raise the ova quality by reducing TNF-alpha and IL-6 levels to improve the living micro-environment for the ova.

OBJECTIVE: To observe the effect of human follicular fluid (HFF) from endometriosis (EM) patients treated with Quyu Jiedu Granule (QJG) on mouse embryonic development. METHODS: Cultured 2-cell mouse embryos were divided into three groups. To the medium of Group A (70 embryos), HFF from endometriosis patients treated with QJG was added; to that of Group B (60 embryos), HFF from endometriosis patients untreated with QJG, and to Group C (59 embryos), HFF from patients with fallopian tube obstruction was added. The percentages of embryos developed to 8-cell stage, morula stage and blastula stage were counted, and the early stage number and rate of high-quality embryo were measured. RESULTS: Among the 70 embryos in Group A, 53 (75.71%) developed to 8-cell stage, 48 (68.57%) to morula stage and 45 (64.28%) to blastula stage; while in the 60 embryos of Group B, the corresponding number (percentage) were 34 (56.67%), 29 (48.33%), 21 (35.00%), respectively, showing significant differences between groups (P < 0.05). High-quality of embryo was 61 (87.14%) in Group A and 44 (73.3%) in Group B, the difference between groups also showed statistical significance (P < 0.05). CONCLUSION: HFF from endometriosis patients is toxic to 2-cell mouse embryos, but after treated by QJG, it could elevate the quality of cultured mouse embryo in the early stage.

OBJECTIVE: To observe the effects of Quyu Jiedu Granule, a compound traditional Chinese herbal medicine for removing blood stasis and expelling superficial evils, on the quality of oocytes and the expressions of tumor necrosis factor-alpha (TNF-alpha)and interleukin-6 (IL-6) mRNAs in ovarian granulosa cells of endometriosis (EM) rats. METHODS: Forty EM rats were randomly divided into two groups: experimental group and control group. There were 20 EM rats in each group. The uteri of another 20 SD rats were drawn in sham-operated group. The number and percentage of high quality oocytes and the levels of TNF-alpha and IL-6 mRNA expressions in the granulosa cells of EM rats were detected by using reverse transcription-polymerase chain reaction. RESULTS: The number and percentage of high quality oocytes in the experimental group were significantly higher than those in the control group (P<0.05), and the levels of TNF-alpha and IL-6 mRNAs in granulose cells in the experimental group were significantly lower than those in the control group (P<0.05). CONCLUSION: The increase of the TNF-alpha and IL-6 mRNA expressions in ovarian granulose cells of EM rats leads to the decrease of the oocyte quality. The mechanism of Quyu Jiedu Granule in improving the quality of oocytes may be related to the decrease of TNF-alpha and IL-6 mRNA expressions in ovarian granulosa cells.
