This study organizes and classifies acupuncture-related standards, and analyzes the current status and existing problems. At present, there are 63 international standards, 40 national standards, 6 industry standards, 43 local standards, and 194 group standards related to acupuncture. The current situation is characterized by an irrational standard structure and incomplete coverage of relevant fields; insufficient coordination mechanisms, with overlapping and redundant standards; slow updating of standards, lacking timeliness. It is suggested that the development of acupuncture-related standards should be promoted through the following measures: improving the structure of the standard system and establishing a sound collaborative management mechanism; implementing full-cycle management of standards in line with technological advancements; and building an acupuncture standards information platform to provide one-stop services.

Objective:To investigate the predictive value of plasma exosomal microRNA (miR)-124-3p in the risk of chronic cerebral hypoperfusion (CCH).Methods:A case-control study. Thirty patients who were diagnosed with CCH (CCH group) based on cranial artery spin labeling (ASL) in the neurology outpatient clinic of Sichuan Provincial People′s Hospital from March 2022 to June 2022 and 30 healthy volunteers (control group) were included. Age, gender, smoking history, alcohol consumption history, diabetes history, hypertension, hyperlipidemia history, uric acid, fasting blood glucose, homocysteine and plasma exosomal miR-124-3p expression level were compared between the two groups. Comparisons of categorical variables were analyzed by either χ2 test or Fisher′s exact test. If the data of continuous variables followed a normal distribution, they were expressed as mean±standard deviation (SD) and compared by t-test for two independent samples; otherwise, the data were expressed as M( Q1, Q3), and analyzed by Mann-Whitney U test for comparison between two groups. The correlation between cerebral blood flow and exosomal miR-124-3p levels was analyzed by Pearson′s correlation. Binary multifactorial logistic regression analysis was used to determine the risk factors associated with CCH, and corresponding odds ratios ( OR) and 95% confidence intervals ( CI) were calculated. P<0.05 was considered significant. Results:There was no significant difference in age (64±8 vs. 60±8 years old), gender (33.3% vs. 30.0%), history of smoking (20.0% vs. 3.3%), alcohol consumption (20.0% vs. 6.7%), diabetes mellitus (13.3% vs. 13.3%), hypertension (53.3% vs. 30.0%), history of hyperlipidemia (46.7% vs. 36.7%), uric acid (288±60 vs.319±67 μmol/L), and fasting glucose [4.99(4.63, 5.91) vs. 5.28(5.09, 6.05) mmol/L] and homocysteine [11.35(10.18, 13.08) vs.11.00(9.78, 13.03) μmol/L] between the CCH and control groups ( P>0.05). Plasma exosomal miR-124-3p expression was significantly higher in the CCH group than in the control group [13.08 (8.59, 21.55) vs. 2.85 (1.44, 5.10), respectively; U=169.50, P<0.001]. Pearson′s correlation test showed that the level of exosomal miR-124-3p was negatively correlated with cerebral blood flow in the hypoperfused region in patients with CCH ( r=-0.932, P<0.001). Multi-factor logistic regression analysis showed that plasma exosomal miR-124-3p was independently associated with the risk of CCH ( OR=1.169,95% CI 1.063-1.286, P=0.001). Conclusions:The expression of plasma exosomal miR-124-3p is negatively correlated with cerebral blood flow in areas of low perfusion and is an independent risk factor for CCH. Plasma exosomal miR-124-3p may thus serve as a valid biomarker for CCH risk prediction.

Objective:To investigate the application values of bone marrow morphology, bone marrow immunohistochemistry, flow cytometry, fluorescence in situ hybridization (FISH) and cytogenetic testing in newly diagnosed multiple myeloma.Methods:A total of 280 patients with multiple myeloma who were newly diagnosed in Tianjin KingMed Diagnosis Center from September 2018 to August 2019 were collected. The bone marrow biopsy was carried out according to the routine method, and bone marrow morphology, bone marrow immunohistochemistry, flow cytometry immunophenotyping, FISH and cytogenetic testing were performed. The detection results of each method were compared.Results:In 280 patients, the bone marrow immunohistochemistry results showed that the median ratio of plasma cells was higher than those of bone marrow morphology (20 cases, 0.675 vs. 0.300) and flow cytometry (47 cases, 0.650 vs. 0.147), and the differences were statistically significant ( Z = -3.883, P < 0.01; Z = -5.947, P < 0.01). Flow cytometry results showed that the positive rates of CD38, CD138, κ, λ, CD56 and CD19 were 100.0% (280/280), 100.0% (280/280), 57.5% (161/280), 42.5% (119/280), 62.1% (174/280) and 19.3% (54/280); bone marrow immunohistochemistry results showed that the positive rates of CD38, CD138, κ, λ and CD56 were 98.9% (277/280), 98.2% (275/280), 57.5% (161/280), 42.5% (119/280) and 62.1% (174/280); there was no statistical difference between the two detection methods in the detection coincidence rate of the same detection index (all P > 0.05). Among patients who underwent FISH detection, the detection rate of gene abnormalities was 69.9% (93/133); the detection rate of abnormalities by direct fluorescence in situ hybridization (D-FISH) was 42.9% (57/133); the detection rate of abnormalities by CD138 immunomagnetic sorting myeloma cells (MACS)-FISH was 82.7% (110/133). Among patients who underwent G-band karyotyping, the detection rate of abnormal karyotype was 38.5% (85/221). FSIH, especially MACS-FISH, had a higher detection rate of cytogenetic abnormalities than G-band karyotyping, and the difference was statistically significant ( χ2 = 65.697, P < 0.05). Conclusion:The comprehensive application of bone marrow morphology, bone marrow immunohistochemistry, flow cytometry, FISH (especially MACS-FISH), cytogenetic testing and other detection methods is more helpful for the diagnosis of multiple myeloma, and may be useful for prognostic judgment.

OBJECTIVE：To study the effe cts of the water extract from Carpesium cernuum （AECC）on the proliferation ， metastasis and invasion of prostate cancer PC 3 cells. METHODS ：Cells were divided into control group and different concentration groups of AECC （5，10，20，40，80 μg/L），and then treated with relevant medicine or medium for different time （24，48，72 h）. The survival rates of cells were detected. Cells were divided into control group ，and AECC low ，medium and high concentration groups（20，40，80 μg/L）. After cultured for 24 h，Hoechst 33258 staining and flow cytometry were used to detect the apoptosis of cells. The number of cell metastasis and invasion were detected by Transwell assay. RT-qPCR and Western blot assay were applied to detect the mRNA and protein expression of β-catenin signaling pathway related migration and apoptosis proteins （β-catenin， MMP-7，c-Myc，caspase-3，Bcl-2 and Bax ）in AECC low and medium concentration groups. RESULTS ：With the increase of the concentration and culture time ，the survival rates of cells in AECC different concentration groups were significantly lower than control group （P＜0.05 or P＜0.01），and showed a decreasing trend. Compared with control group ，the early apoptosis rate （except the medium concentration group ）and the number of cell metastasis and invasion in AECC groups ，the mRNA and protein expression of MMP- 7，c-Myc（except for the low concentration group ）and Bcl- 2（except for mRNA of the low concentration group）in AECC low and medium concentration groups were decreased significantly （P＜0.05 or P＜0.01）. Late apoptosis rate of AECC groups ，the mRNA and protein expression of β-catenin，caspases-3（except for the low concentration group ），Bax（except for mRNA of the low concentration group ）in AECC low and medium concentration groups were increased significantly （P＜0.05 or P＜0.01）. CONCLUSIONS ：AECC could inhibit the proliferation ，metastasis and invasion of PC 3 cells；the mechanism of which may be associated with regulating the expression of β-catenin signaling pathway related migration and apoptotic factors.

Objective:To investigate the effect of electroacupuncture (EA) on synaptic damage to hippocampal neurons in rats with sepsis-associated encephalopathy (SAE).Methods:A total of 48 healthy adult male Sprague-Dawley rats, weighing 250-300 g, were divided into 4 groups ( n=12 each) using a random number table method: sham operation group (Sham group), SAE group, SAE+ EA group and SAE+ sham EA group (SAE+ SEA group). SAE was induced by cecal ligation and puncture in anesthetized rats.Baihui, Quchi and Zusanli acupoints were stimulated with constant voltage (2/15 Hz) and disperse-dense waves for 30 min once a day for 10 consecutive days, and the stimulation intensity was defined as less than 1.5 mA causing slight muscle contraction at 2 days before operation in group SAE+ EA.In group SAE+ SEA, stimulating electrodes were placed at the points 5 mm lateral to the corresponding acupoints, but no electrical stimulation was applied.On day 14 after operation, the rats were sacrificed, and hippocampal tissues were obtained and stained with haematoxylin and eosin for examination of the pathological changes in the hippocampal CA1 region, for determination of the expression of synaptophysin (SYN) and postsynaptic density protein 95 (PSD-95) (by Western blot), and for calculation of dendritic spine density of neurons in the hippocampal CA1 area (using Golgi staining) and pyramidal neurons counts. Results:Compared with Sham group, the expression of SYN and PSD-95 in hippocampus was significantly decreased, and the basal and apical dendrite spine density of neurons in hippocampal CA1 area was decreased in SAE group, the expression of PSD-95 was decreased, and the apical dendrite spine density of neurons in the hippocampal CA1 area was increased in SAE+ EA group, and the pyramidal neuron counts in the hippocampal CA1 area were reduced in SAE, SAE+ EA and SAE+ SEA groups ( P<0.05). Compared with group SAE, the expression of SYN and PSD-95 was significantly up-regulated, the basal and apical dendrite spine density of neurons in the hippocampal CA1 area was increased and the pyramidal neuron counts were increased in group SAE+ EA ( P<0.05), the pathological damage of hippocampal CA1 area was alleviated and no significant change was found in the parameters mentioned above in group SAE+ SEA ( P>0.05). Compared with group SAE+ EA, the expression of SYN and PSD-95 was down-regulated, the basal and apical dendrite spine density of neurons in the hippocampal CA1 area was decreased, and the pyramidal neuron counts were reduced in SAE+ SEA group ( P<0.05). Conclusion:The mechanism by which EA alleviates SAE may be related to reducing synaptic damage to hippocampal neurons in rats.

Objective:To evaluate the role of heme oxygenase-1 (HO-1) in electroacupuncture (EA)-induced alleviation of cognitive dysfunction in mice with sepsis-associated encephalopathy (SAE) and the relationship with mitochondrial fusion-division balance.Methods:Thirty clean-grade male C57BL/6 mice (24 wide-type mice and 6 HO-1 knockout mice), aged 6-8 weeks, weighing 18-22 g, were studied.Twenty-four wide-type mice were divided into 4 groups ( n=6 each) using a random number table method: control group (group C), SAE group, SAE plus EA group (group SAE+ EA), and SAE plus sham EA group (group SAE+ SEA). HO-1 knockout mice in which EA intervention was performed after establishing SAE model served as SAE plus EA plus HO-1 knockout group (group SAE + EA+ H). Sepsis was induced by intraperitoneally injecting lipopolysaccharide 15 mg/kg.EA of Zusanli and Baihui acupoints lasting 30 min was performed after intraperitoneal injection of lipopolysaccharide once a day for 5 consecutive days in SAE+ EA and SAE+ EA+ H groups.Cognitive function was assessed using Morris water maze test before stimulation every day.The mice were sacrificed, and hippocampal tissues were removed for detection of the expression of mitofusin 2 (Mfn2), optic atrophy 1 (OPA1) and mitochondrial dynamin-related protein 1 (Drp1) by Western blot. Results:Compared with group C, the expression of Mfn2 and OPA1 was significantly down-regulated, the escape latency was prolonged, and the time spent in the target quadrant was shorted in SAE, SAE+ SEA and SAE+ EA+ H groups, and the expression of Drp1 was significantly up-regulated in SAE, SAE+ EA, SAE+ SEA and SAE+ EA+ H groups ( P<0.05). Compared with group SAE, the expression of Mfn2 and OPA1 was significantly up-regulated, the expression of Drp1 was down-regulated, the escape latency was shortened, and the time spent in the target quadrant was prolonged in group SAE+ EA ( P<0.05), and no significant change was found in the parameters mentioned above in group SAE+ SEA ( P>0.05). Compared with group SAE+ EA, the expression of Mfn2 and OPA1 was significantly down-regulated, the expression of Drp1 was up-regulated, the escape latency was prolonged, and the time spent in the target quadrant was shortened in SAE+ SEA and SAE+ EA+ H groups ( P<0.05). Conclusion:HO-1 is involved in EA-induced alleviation of cognitive dysfunction in mice with SAE, and the mechanism may be related to the regulation of mitochondrial mitochondrial fusion-division balance.
