BACKGROUND:Postoperative delirium is one of the serious complications after total knee arthroplasty,usually occurring 1-5 days after surgery,with confusion and cognitive impairment as the main manifestations,which is not conducive to the recovery of joint function in elderly patients.At present,the risk factors affecting delirium after total knee arthroplasty in the elderly are not clear,and there is a lack of clinical prediction studies to directly present them for promotion and application. OBJECTIVE:To explore the risk factors of delirium after total knee arthroplasty in elderly patients and establish a prediction model of nomogram. METHODS:Medical record data of 116 elderly patients receiving total knee arthroplasty treated in Ganzhou Hospital of Traditional Chinese Medicine,Jiangxi University of Chinese Medicine from January 2019 to December 2021 were retrospectively analyzed,of which 29 elderly patients with delirium after total knee arthroplasty were selected as the observation group,and the remaining 87 elderly patients without delirium after total knee arthroplasty were selected as the control group.Preoperative general clinical data,laboratory examination results,and surgical data were compared between the two groups.Multivariate Logistic regression analysis was used to analyze risk factors for delirium after total knee arthroplasty in elderly patients.The receiver operating characteristic curve was used to analyze the independent risk factors and obtain the best cut-off value.The nomogram model was constructed by R software. RESULTS AND CONCLUSION:(1)There were significant differences in age,cerebrovascular accident history,preoperative hospital stay,preoperative albumin,hemoglobin,American Society of Anesthesiologists classification,operation time,anesthesia time,and intraoperative blood transfusion volume between the two groups(P<0.05).(2)Multivariate Logistic regression analysis showed that old age,long hospital stay before surgery,high American Society of Anesthesiologists classification grade,and long operation time were risk factors for postoperative delirium in elderly knee arthroplasty patients,while high albumin and high hemoglobin were protective factors for postoperative delirium in elderly knee arthroplasty patients.(3)The areas under the curve of age,preoperative hospital stay,albumin,hemoglobin,American Society of Anesthesiologists classification grade,and operation time were 0.784,0.706,0.853,0.762,0.617,and 0.542,respectively.The optimal cut-off values were 75 years,7 days,40 g/L,125 g/L,3 and 200 minutes,respectively.(4)After internal data for verification,the consistency index was 0.974.The actual curve of the model was in good agreement with the ideal curve.(5)These results indicate that this nomogram model based on old age,long hospital stay,high American Society of Anesthesiologists classification grade,low albumin,low hemoglobin,and long operation time has far-reaching clinical significance for early identification,early warning and diagnosis of delirium risk in elderly patients after total knee arthroplasty.

ObjectiveTo investigate the value of percutaneous and intravenous contrast-enhanced ultrasound(P-Ⅳ-CEUS) in sentinel lymph nodes(SLNs) after resection of early-stage primary breast cancer. MethodsA retrospective analysis was done on the clinical and imaging data of 42 early breast cancer patients. Following primary tumor resection, all these patients underwent reoperation in our hospital. SLNs were examined by preoperative P-Ⅳ-CEUS and intraoperative sentinel lymph node biopsy(SLNB) was performed by using Methylene blue as a tracer. Then we analyzed the detection and false-negative rate in CEUS and SLNB respectively. By using the surgical pathological results as the gold standard, the diagnostic efficacy of CEUS for SLNs was explored. ResultsThe detection rate and false negative rate of SLNs in percutaneous contrast-enhanced ultrasound (P-CEUS) were 92.9% (39/42) and 7.1% (3/42), respectively. The detection rate in methylene blue staining was 100% (41/41) and one patient underwent neoadjuvant therapy due to biopsy-confirmed metastasis. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of P-Ⅳ-CEUS were 66.7% (2/3), 100% (37/37), 100% (2/2), 97.3% (36/37) and 97.4% (38/39), respectively. ConclusionsP-Ⅳ-CEUS after resection of early-stage primary breast cancer can accurately detect SLNs and characterize their status, which is a reliable clinical basis for reducing invasive SLNB.

ObjectiveTo develop a deep learning system for early ultrasound screening of developmental dysplasia of the hip (DDH), a new smart-hip ultrasound technique (S-hip), and to validate its clinical application. MethodsWe selected 11,100 annotated and reviewed coronal ultrasound images of infant hips between November 2021 and August 2022, 8,100 of which were used for the training set and 3,000 for the test set, to build a S-hip deep learning system. To verify the consistency between the automated measurement by S-hip and the manual measurements by sonographers, 174 standard coronal ultrasound images of 87 infants' bilateral hips were acquired, then α angle, β angle and femoral head coverage (FHC) were measured by S-hip, an ultrasound expert and a resident. The measurement data and the time required for the measurements were recorded and statistically analyzed. Another 100 standard coronal ultrasound images of the hips were randomly selected and measured twice respectively by the ultrasound expert and resident to assess the intra-sonographer repeatability. ResultsThe intraclass correlation coefficient (ICC) (95% CI) values of α angle, β angle and FHC results measured by S-hip and ultrasound expert were 0.799 (0.738, 0.847), 0.798 (0.737, 0.846) and 0.934 (0.954, 0.975), respectively. Those values measured by the ultrasound expert and resident were 0.725 (0.645, 0.789), 0.674 (0.583, 0.748) and 0.931 (0.908, 0.949), respectively. The mean absolute errors (MAE) of α angle, β angle and FHC results between measurements by S-hip and ultrasound expert were 2.69 °, 4.43 ° and 2.47%, respectively. The time required for measurements by S-hip, ultrasound expert and resident was (1.59±0.36) s, (18.76±2.23) s and (19.45±2.76) s, respectively. The automated measurement by S-hip cost much shorter time than the manual measurements by sonographers and the difference was statistically significant (P<0.001). The ICC (95% CI) values of α angle, β angle and FHC results between two measurements by the ultrasound expert were 0.943 (0.916, 0.961), 0.959 (0.940, 0.972), and 0.981 (0.971, 0.987), respectively. Those values by the ultrasound resident were 0.884 (0.833, 0.921), 0.921 (0.884, 0.946), and 0.962 (0.944, 0.974). ConclusionThe S-hip based on a deep learning system is a highly reliable automated technique to accurately measure α angle, β angle and FHC. Compared with ultrasound residents, S-hip allows for a more simplified and significantly quicker measurement, which may enhance the widespread use of hip ultrasound screening in infants.

Background/Aims@#A high-quality sample allows for next-generation sequencing and the administration of more tailored precision medicine treatments. We aimed to evaluate whether heparinized wet suction can obtain higher quality samples than the standard dry-suction method during endoscopic ultrasound (EUS)-guided biopsy of pancreatic masses. @*Methods@#A prospective randomized crossover study was conducted. Patients with a solid pancreatic mass were randomly allocated to receive either heparinized wet suction first or dry suction first. For each method, two needle passes were made, followed by a switch to the other method for a total of four needle punctures. The primary outcome was the aggregated white tissue length. Histological blood contamination, diagnostic performance and adverse events were analyzed as secondary outcomes. In addition, the correlation between white tissue length and the extracted DNA amount was analyzed. @*Results@#A total of 50 patients were enrolled, and 200 specimens were acquired (100 with heparinized wet suction and 100 with dry suction), with one minor bleeding event. The heparinized wet suction approach yielded specimens with longer aggregated white tissue length (11.07 mm vs 7.96 mm, p=0.001) and less blood contamination (p=0.008). A trend towards decreasing tissue quality was observed for the 2nd pass of the dry-suction method, leading to decreased diagnostic sensitivity and accuracy, although the accumulated diagnostic performance was comparable between the two suction methods. The amount of extracted DNA correlated positively to the white tissue length (p=0.001, Spearman ̕s ρ=0.568). @*Conclusions@#Heparinized wet suction for EUS tissue acquisition of solid pancreatic masses can yield longer, bloodless, DNA-rich tissue without increasing the incidence of adverse events (ClinicalTrials.gov. identifier NCT04707560).

Objective@#Problematic use of social media (PUSM) may affect sleep quality and self-stigma in people with schizophrenia and consequently reduce their quality of life (QoL). This longitudinal study investigated if sleep quality and self-stigma mediated relationships between PUSM and QoL. @*Methods@#One-hundred-and-ninety-three outpatients with schizophrenia were recruited from a psychiatric center in Taiwan from April 2019 to August 2021 and participated in a longitudinal study at intervals of three months between measurements. QoL was assessed using the World Health Organization Quality of Life Questionnaire Brief Version; sleep quality using the Pittsburgh Sleep Quality Index; self-stigma using the Self-Stigma Scale-Short; and PUSM using the Bergen Social Media Addiction Scale. Via SPSS 20.0, general estimating equation models assessed temporal associations between variables. Via R software, mediating effects of self-stigma and sleep quality were examined through Monte Carlo simulations with 20,000 repetitions. @*Results@#Mean scores of physical, psychological, social and environmental QoL ranged from 11.86 to 13.02. Mean scores of sleep quality and self-stigma were 9.1±4.5 and 2.2±0.8, respectively. Sleep quality and self-stigma were directly related to QoL (p<0.001) and mediated indirect relationships between PUSM and all components of QoL with a range of 95% confidence intervals spanning from -0.0591 to -0.0107 for physical QoL; -0.0564 to -0.0095 for psychological QoL; -0.0292 to -0.0035 for social QoL; and -0.0357 to -0.0052 for environmental QoL. @*Conclusion@#Sleep quality and self-stigma mediated relationships between PUSM and QoL in people with schizophrenia. Developing interventions targeting PUSM, sleep, and self-stigma may help improve QoL in people with schizophrenia.

Objective: To retrospectively investigate the clinical data, radiological characteristics, treatment, and outcome of patients with parenchymal neuro-Behcet's disease (P-NBD) with particular emphasis on dizziness. Methods: This was a cross-sectional study of clinical data from 25 patients with a confirmed diagnosis of P-NBD who were admitted to the Department of Neurology of the First Medical Center of Chinese People's Liberation Army General Hospital between 2010 and 2022. The median age of the population was 37 years (range: 17-85 years). Clinical data were retrospectively analyzed, including gender, age of onset, disease duration, clinical manifestations, serum immune indicators, cerebrospinal fluid (CSF) routine biochemical and cytokine levels, cranial and spinal magnetic resonance imaging (MRI) findings, treatment, and outcome. Results: The majority of patients were male (16 cases; 64.0%), the mean age of onset was (28±14) (range: 4-58 years), and the disease course was acute or subacute. Fever was the most common clinical presentation, and the complaint of dizziness was not uncommon (8/25 patients). Analysis of serum immune indices, including complement (C3 and C4), erythrocyte sedimentation rate, interleukin-1 (IL-1), IL-6, IL-8 and tumor necrotic factor-alpha were abnormal in 80.0% of patients (20/25). Most of the 16/25 patients who underwent lumbar puncture tests had normal intracranial pressure and increased CSF white cell count and protein [median values were 44 (15-380) ×106/L and 0.73 (0.49-2.81) g/L, respectively]. Of the five patients who underwent CSF cytokine tests, four patients had abnormal results; of these, an elevated level of IL-6 was most common, followed by IL-1 and IL-8. The most common site of involvement in cranial MRI was the brainstem and basal ganglia (60.0% respectively), followed by white matter (48.0%) and the cortex (44.0%). Nine cases (36.0%) showed lesions with enhancement and six cases (24.0%) showed mass-like lesions. Three patients (12.0%) patients had lesions in the spinal cord, most frequently in the thoracic cord. All patients received immunological intervention therapy; during follow up, the majority had a favorable outcome. Conclusions: P-NBD is an autoimmune disease with multiple system involvement and diverse clinical manifestations. The symptom of dizziness is not uncommon and can be easily ignored. Early treatment with immunotherapy is important and can improve the outcome of these patients.

Objective@#Social media addiction and internet gaming disorder may cause mental health problems among a minority of university students. The Bergen Social Media Addiction Scale (BSMAS) and the 9-item Internet Gaming Disorder Scale-Short Form (IGDS9-SF) are commonly used worldwide. However, they have not been translated or validated into Indonesian. The present study aimed to translate and validate the BSMAS and IGDS9-SF in an Indonesian context among young adults. @*Methods@#A multi-center, web-based cross-sectional study was conducted among 458 university students (74% female; mean age 22.5 years) in Indonesia from June to December 2021. The BSMAS and IGDS9-SF were translated into Indonesian. Internal consistency (using Cronbach’s α and McDonald’s ω) and factor structure (using confirmatory factor analysis) of the two instruments were examined. Concurrent validity of BSMAS and IGDS9-SF was examined using their correlations with two external concepts: nomophobia and psychological distress. @*Results@#Internal consistency of the Indonesian BSMAS and IGDS9-SF were both acceptable (Cronbach’s α=0.80 and 0.90; McDonald’s ω=0.86 and 0.92). Both instruments were unidimensional with good factor loadings (0.54–0.78 for BSMAS; 0.63–0.79 for IGDS9-SF). Moreover, BSMAS and IGDS9-SF had stronger associations with nomophobia (r=0.58 and 0.12; p<0.001) than with psychological distress (r=0.43 and 0.15; p<0.001). @*Conclusion@#The Indonesian versions of the BSMAS and IGDS9-SF had good psychometric properties in terms of linguistic validity, unidimensionality, and reliability. The findings indicate the tools are appropriate for assessing the risk of social media addiction and internet gaming disorder among university students in Indonesia.

OBJECTIVE@#To compare the efficacy of eltrombopag combined with cyclosporine A (CsA) and CsA alone in patients with transfusion-dependent non-severe aplastic anemia (TD-NSAA).@*METHODS@#The clinical data of 76 patients with treatment-naive TD-NSAA in Ningde Municipal Hospital of Ningde Normal University and Affiliated Hospital of Nantong University from December 2017 to June 2021 were retrospectively analyzed. Among them, 45 cases were treated with eltrombopag combined with CsA, and 31 patients with compatible baseline characters were treated with CsA alone. The efficacy of patients between the two groups was compared, and the factors affecting the curative effects were also analyzed.@*RESULTS@#There were significant differences in hematological response (HR) and complete response(CR) rates between the two groups at 3, 6, 12 months, and follow-up endpoint of treatment (P<0.05). With the prolongation of eltrombopag treatment time, the curative effect increased gradually, and the patients achieved more CR and HR rates by the end of the follow-up period. Simultaneously, with the increase in the maximum stable dose of eltrombopag, the HR rate increased gradually. The megakaryocyte count in eltrombopag group was higher than that in control at 6 and 12 months (P<0.05). Compared with the control group, the median time of platelet transfusion independence in eltrombopag group was more shorter (P=0.018), and the median platelets transfusion volume was lower (P=0.009). At 3, 6, 12 months after eltrombopag, the change of platelet in eltrombopag group was higher than that in the control group (P<0.05). Analysis of related factors affecting the efficacy showed that sex, age, iron overload, platelet count before treatment had no effect on the efficacy, and the median maximum stable dosage and the administration period for eltrombopag were related to the curative effect. The patients of eltrombopag group experienced adverse events of varying degrees, but the reactions were mild and mostly tolerated.@*CONCLUSION@#Eltrombopag can effectively improve the hematopoietic response and promote platelet recovery for TD-NSAA patients with relatively more residual hematopoietic cells, and it is safe and well tolerated.

Entinostat plus exemestane in hormone receptor-positive (HR+) advanced breast cancer (ABC) previously showed encouraging outcomes. This multicenter phase 3 trial evaluated the efficacy and safety of entinostat plus exemestane in Chinese patients with HR + ABC that relapsed/progressed after ≥1 endocrine therapy. Patients were randomized (2:1) to oral exemestane 25 mg/day plus entinostat (n = 235) or placebo (n = 119) 5 mg/week in 28-day cycles. The primary endpoint was the independent radiographic committee (IRC)-assessed progression-free survival (PFS). The median age was 52 (range, 28-75) years and 222 (62.7%) patients were postmenopausal. CDK4/6 inhibitors and fulvestrant were previously used in 23 (6.5%) and 92 (26.0%) patients, respectively. The baseline characteristics were comparable between the entinostat and placebo groups. The median PFS was 6.32 (95% CI, 5.30-9.11) and 3.72 (95% CI, 1.91-5.49) months in the entinostat and placebo groups (HR, 0.76; 95% CI, 0.58-0.98; P = 0.046), respectively. Grade ≥3 adverse events (AEs) occurred in 154 (65.5%) patients in the entinostat group versus 23 (19.3%) in the placebo group, and the most common grade ≥3 treatment-related AEs were neutropenia [103 (43.8%)], thrombocytopenia [20 (8.5%)], and leucopenia [15 (6.4%)]. Entinostat plus exemestane significantly improved PFS compared with exemestane, with generally manageable toxicities in HR + ABC (ClinicalTrials.gov #NCT03538171).
摘要
This study aims to investigate the effects of Blaps rynchopetera Fairmaire and/or cyclophosphamide on the proliferation and apoptosis of lung cancer cells and decipher the underlying mechanism. B. rynchopetera and cyclophosphamide-containing serum and blank serum were prepared from SD rats. Cell counting kit-8(CCK-8) assay was employed to examine the proliferation of lung cancer cell lines A549 and Lewis treated with corresponding agents. The Jin's formula method was used to evaluate the combined effect of the two drugs. According to the evaluation results, appropriate drug concentrations and lung cancer cell line were selected for subsequent experiments, which included control, B. rynchopetera, cyclophosphamide, B. rynchopetera + cyclophosphamide, and B. rynchopetera + Wnt/β-catenin pathway agonist lithium chloride(LiCl) groups. Immunocytochemistry was employed to measure the expression of proliferation-related proteins in Lewis cells after drug interventions. Flow cytometry was employed to determine the cell cycle and apoptosis. The expression levels of proliferating cell nuclear antigen(PCNA), cyclinD1, B-cell lymphoma 2(Bcl-2), Bcl-2-assiocated X protein(Bax), Wnt1, and β-catenin were determined by Western blot. The results showed that B. rynchopetera and/or cyclophosphamide significantly inhibited the proliferation of A549 and Lewis cells. Compared with B. rynchopetera alone, the combination increased the inhibition rate on cell proliferation. The combination of B. rynchopetera and cyclophosphamide demonstrated a synergistic effect according to Jin's formula-based evaluation. Compared with the control group, the B. rynchopetera, cyclophosphamide, and B. rynchopetera + cyclophosphamide groups showed increased proportion of Lewis cells in G_0/G_1 phase, increased apoptosis rate, up-regulated expression of Bax, and down-regulated expression of PCNA, cyclinD1, Bcl-2, Wnt1, and β-catenin. Compared with the cyclophosphamide group, the combination group showed increased proportion of cells in G_0/G_1 phase, increased apoptosis rate, up-regulated expression of Bax, and down-regulated expression of PCNA, cyclinD1, Bcl-2, Wnt1, and β-catenin. Compared with the B. rynchopetera group, the B. rynchopetera + LiCl group had deceased proportion of cells in G_0/G_1 phase, decreased apoptosis rate, down-regulated expression of Bax, and up-regulated expression of PCNA, cyclinD1, Bcl-2, Wnt1, and β-catenin. The results indicated that B. rynchopetera could inhibit the proliferation, arrest the cell cycle, and induce the apoptosis of lung cancer cells by inhibiting the Wnt/β-catenin signaling pathway. Moreover, B. rynchopetera had a synergistic effect with cyclophosphamide.

Axial myopathy is a general term for a group of myopathy involving the axial muscles. It refers to a group of skeletal myopathy in which paraspinal muscles are individually or significantly affected, with or without the involvement of whole body skeletal muscles. Axial muscle weakness is often ignored in clinical practice. The evaluation of axial muscle is mainly the evaluation of the paraspinal muscles (erector spinae) in current literature. The clinical manifestations of paraspinal muscle weakness are dropped head syndrome and camptocormia. Physical examination and skeletal muscle magnetic resonance imaging, especially the whole body muscle magnetic resonance scan, are vital for the evaluation of axial muscle. It is of great clinical significance to increase attention to the diagnosis and differentiation of axial myopathy, which is helpful to avoid missing treatable diseases and improve the understanding and early recognition of associated myopath.

From January 2020 to April 2021, 17 consecutive sNPDR patients with 17 eyes who were diagnosed and received PPV treatment at the Zhongshan Ophthalmic Center of Sun Yat-sen University were included in the study. There were 12 males with 12 eyes and 5 females with 5 eyes; the average age was 55 years old; the average duration of diabetes was 11 years; the average glycosylated hemoglobin was 7.9%. Before the operation and 1, 3, and 6 months after the operation, all the affected eyes underwent best corrected visual acuity (BCVA), standard 7-field fundus color photography, and optical coherence tomography angiography (OCTA). An OCTA instrument was used to scan the macular area of the affected eye with in the range of 3 mm×3 mm to measure the central subfoveal thickness (CST), the thickness of the ganglion cell complex (GCC) in the macular area, the thickness of the retinal nerve fiber layer (RNFL), and the superficial capillary plexus (SCP) vessel density and perfusion density in the macular area, macular avascular zone (FAZ) area, a-circularity index (AI). Before the operation and 6 months after the operation, the least significant difference test was used for the pairwise comparison.Results:Before the operation, 1, 3, and 6 months after the operation, the FAZ area of the macular area were 0.34±0.14, 0.35±0.10, 0.37±0.10, 0.36±0.13 mm 2, respectively; AI were 0.52±0.13, 0.54±0.11, 0.57±0.10, 0.60±0.11; CST was 282.6±66.7, 290.4±70.9, 287.2±67.5, 273.2± 49.6 μm; GCC thickness were 77.1±15.5, 74.3±13.9, 72.6±16.2, 78.5±18.3 μm; the thickness of RNFL was 97.9±13.8, 101.3±14.6, 97.7±12.0, 96.1±11.4 μm, respectively. The overall blood flow density of SCP in the macula were (16.79±1.43)%, (16.71±1.82)%, (17.30±2.25)%, (17.35±1.22)%; the overall perfusion density were 0.32±0.02, 0.32±0.03, 0.33±0.03, 0.33±0.02, respectively. After the operation, the CST increased first and then decreased; the thickness of RNFL increased 1 month after the operation, and then gradually decreased. Comparison of the parameters before and 6 months after the operation showed that the AI improved, and the difference was statistically significant ( P=0.049); the difference in FAZ area and the thickness of CST, GCC, and RNFL was not statistically significant ( P=0.600, 0.694, 0.802, 0.712); There was no statistically significant difference in the retina SCP blood flow density and perfusion density in the macular area ( P=0.347, 0.361). Conclusion:Compared with before surgery, there is no significant change in macular structure and blood flow density in sNPDR patients within 6 months after minimally invasive PPV.

Objective@#To investigate the experience of child sexual abuse (CSA) and depressive symptoms among young men who sex with men (YMSM) in Guangzhou, and then to explore the impact of CSA on depressive symptoms.@*Methods@#A convenient sampling method was used to recruit MSM. YMSM who aged 18-24 and have lived in Guangzhou for more than 3 months were included in this study. Data on demographic characteristics, homosexual partners seeking behaviors, sexual orientation, CSA experience and depression were collected through an electronic questionnaire. χ 2 tests were used to compare the proportion of CSA and depressive symptoms among YMSM with different characteristics. Logistic regressions were preformed to assess the impact of CSA on depression.@*Results@#The proportion of CSA experience and depressive symptoms among participants were 31.51% (115/365) and 47.95% (175/365), respectively. Participants with junior high school education or lower and who sought homosexual partners offline reported(75.00%,62.22%) a higher proportion of depressive symptoms( χ 2=7.97,4.19, P <0.05). After adjusting for factors e.g. ethnicity, residence, resident duration in Guangzhou, studentship, education, monthly income, sexual orientation and homosexual partners seeking behaviors, the multivariable Logistic regression model showed that YMSM with CSA experience (a OR=1.81, 95%CI =1.12-2.93) were more likely to have depressive symptoms than those without CSA experience.@*Conclusion@#The prevalence of CSA experience and depressive symptom is relatively high among YMSM in Guangzhou, and CSA experience is associated with higher risk of depressive symptoms. More attention should be paid to strengthen the psychological intervention for YMSM, especially for those who experienced CSA, so as to reduce the risk of depression and improve mental health among YMSM.

OBJECTIVE@#To observe the effect of wheat-grain moxibustion at "Dazhui" (GV 14) on the expressions of Beclin-1 and GRP78 in spinal dorsal horn in rats with cervical spondylotic radiculopathy (CSR), and to explore the possible analgesic mechanism of wheat-grain moxibustion for CSR.@*METHODS@#A total of 48 SD rats were randomly divided into a sham operation group, a model group, a wheat-grain moxibustion group and a wheat-grain moxibustion+3-MA group, 12 rats in each group. The CSR model was prepared by spinal cord insertion method. Three days after modeling, the rats in the model group were intraperitoneally injected with 1 mL of 0.9% sodium chloride solution; the rats in the wheat-grain moxibustion group were treated with wheat-grain moxibustion at "Dazhui" (GV 14, 6 cones per time) on the basis of the model group; the rats in the wheat-grain moxibustion+3-MA group were intraperitoneally injected with 3-MA solution and wheat-grain moxibustion at "Dazhui" (GV 14, 6 cones per time). The three groups were intervened for 7 days, once a day. The gait score and mechanical pain threshold were observed before treatment and 7 days into treatment; after the treatment, the expressions of mRNA and protein of Beclin-1 in spinal dorsal horn were detected by real-time fluorescence quantitative PCR and immunohistochemistry; the expression of GRP78 protein in spinal dorsal horn was detected by Western blot method; the autophagosomes and ultrastructure in spinal dorsal horn neurons were observed by electron microscope.@*RESULTS@#After the treatment, compared with the sham operation group, in the model group, the gait score was increased and the mechanical pain threshold was decreased (P<0.01), and the expression of GRP78 protein in spinal dorsal horn was increased (P<0.01). Compared with the model group and the wheat-grain moxibustion+3-MA group, in the wheat-grain moxibustion group, the gait score was decreased and mechanical pain threshold was increased (P<0.01), and the expression of GRP78 protein in spinal dorsal horn was decreased, and the expressions of mRNA and protein of Beclin-1 were increased (P<0.01). Under electron microscope, the ultrastructure of spinal dorsal horn neurons in the wheat-grain moxibustion group was not significantly damaged, and its structure was basically close to normal, and the number of autophagosomes was more than the other three groups.@*CONCLUSION@#Wheat-grain moxibustion at "Dazhui" (GV 14) has analgesic effect on CSR rats. The mechanism may be related to moderately up-regulate the expression of Beclin-1, enhance autophagy and reduce endoplasmic reticulum stress.
