RESUMO
To report the short-term clinical outcome of three cases of distal tibial osteosarcoma treated with a novel 3D-printed ankle fusion prosthesis for limb preservation. The patients were admitted to the Department of Bone Tumor, Shanghai General Hospital from January 2020 to June 2021, with one male and two female cases, aged 18, 12, and 14 years, respectively, all diagnosed with distal tibial osteosarcoma (Ennecking stage IIb). A new self-designed ankle fusion prosthesis was used to perform osteosarcoma resection and prosthetic reconstruction of the distal tibia. The operation time, blood loss, postoperative American Orthopedic Foot and Ankle Society Score (AOFAS) and ankle range of motion were recorded. All the 3 patients successfully completed the operation and were followed up for 22 months, 18 months and 12 months, respectively. The operation time was 140 min, 110 min and 200 min, and the blood loss was 200 ml, 200 ml and 350 ml, respectively. At the last follow-up, the AOFAS were 86, 90 and 95 points, and the range of motion of ankle flexion and extension were 30°, 15° and 30°. There was no local recurrence or lung metastasis at the last follow-up. The novel 3D-printed ankle fusion prosthesis in the distal tibia is safe and effective for the reconstruction of bone defects after resection of osteosarcoma in the distal tibia, and the early postoperative function is satisfactory.

RESUMO
【Objective】 To explore the difference of demographics and influencing factors of motivations between whole blood donors and plasmapheresis donors, so as to provide scientific reference for effective recruitment strategy. 【Methods】 A total of 200 whole blood donors from Guangyuan Blood Center and 200 plasmapheresis donors from Jiange Plasmapheresis Station were selected in August 2021 for on-site questionnaire survey using the method of cross-sectional survey. Statistical analysis was performed by chi-square test, univariate and multivariate logistic regression. 【Results】 There were significant differences in gender, age, occupation, education level and annual family income between whole blood donors and plasmapheresis donors (P<0.05). Males accounted for a large proportion of whole blood donors(124/196, 63.3%), whereas females accounted for a large proportion of plasmapheresis donors(117/198, 59.1%). There was little difference in the number of whole blood donors in different age groups, while the age of plasmapheresis donors was concentrated in 40~59 years old (167/198, 84.3%). In terms of occupation, civil servants (including public institutions) accounted the highest proportion in whole blood donors (41/196, 20.9%), and farmers accounted the highest proportion (152/198, 76.8%) in plasmapheresis donors. The number of whole blood donors increased with the education level, and donors with college/university and above degree accounted the largest proportion (80/196, 40.8%). Plasmapheresis donors with junior middle school education and college/university and above accounted the largest and smallest proportion (49.5% vs 4.5%). The annual family income of whole blood donors ranged from 30 000 to 80 000 yuan accounted the largest proportion (109/196, 55.6%), and the annual family income of plasmapheresis donors less than 30 000 yuan accounted the largest proportion (132/198, 66.7%). 【Conclusion】 There were significant statistical differences in gender, age, education level, occupation and annual family income between whole blood and plasmapheresis donors. Therefore, targeted recruitment strategies should be formulated.
RESUMO
【Objective】 To analyze the dynamic relationship between the setting up of plasmapheresis station and the volume of voluntary blood donation collected using panel vector autoregressive model, so as to provide scientific reference for the management policies of blood stations and plasmapheresis stations in China. 【Methods】 The data collected from blood stations in seven administrative regions of Guangyuan, Sichuan Province from 2011 to 2021, as well as plasma collection data from two plasmapheresis stations in the region within two years since their operation, were collected. A panel vector autoregressive model was constructed. Impulse response analysis and variance decomposition analysis were used to analyze the impact and time lag effects of simulated plasmapheresis station settings on the collection volume of voluntary blood donation. Covariance analysis was used to explore whether the establishment of plasmapheresis station had an impact on the volume of voluntary blood donation collected after excluding the impact of initial value differences. 【Results】 The pulse response results showed that after the plasmapheresis station was set up, there was a negative impact effect on the voluntary blood donation collection volume at the first stage, and its impact began to rise after the second stage, reached the highest value in the third stage, and then began to decline. After the seventh stage, it tended to be stable. However, within the 10 stage range, the confidence interval for the response strength of voluntary blood donation collection volume always included 0, indicating that the response of blood collection volume to the plasmapheresis station setting in the region was not statistically significant. The results of variance decomposition showed that the contribution of collection volume of voluntary blood donation to their own impact reached 94.3%. In terms of the contribution of plasmapheresis station factors, the number of plasma donors has a relatively greater impact on the volume of voluntary blood donation collected(2.2%). Covariance analysis showed that after removing the initial confounding factors, whether to establish a plasmapheresis station had no significant impact on blood donation volume in the two groups of regions (P>0.05). 【Conclusion】 The establishment of a new plasmapheresis station will have a certain impact on blood collection volume of blood stations in the region in a short term, but in the long term, it may not directly affect the voluntary blood donation collection in the region.
RESUMO
【Objective】 To analyze the characteristics and mobility of the overlapping population of voluntary blood donation and plasmapheresis donation, so as to provide a scientific basis for the formulation of recruitment and retention strategies for blood donation and plasmapheresis donation, and to further propose a scientific reference for the decision-making of blood banks and plasmapheresis station management in China. 【Methods】 The basic information of blood donors and plasmapheresis donors in two counties in Guangyuan, Sichuan Province, which carried out whole blood collection and plasmapheresis collection from the establishment of the station to July 31, 2021 was statistically compared and analzed using the chi-square test and Post hoc testing test. 【Results】 As of July 31, 2021, a total of 50 658 people participated in blood donation and 63 375 people participated in plasmapheresis donation in Jiange County and Cangxi County, with a total overlap of 6 189 people. In the two regions, 16 458 (35.2%) people aged 40 to 50, and 35 558 people (56.1%) were over 50 years old. Among the overlapping population, 2 496 (40.3%) were 40 to 50 years old, accounted for the largest proportion, and 3 146 (50.8%) were males. Significant differences were noticed in age (P<0.001) and gender (P<0.001). There was a shift in dontion in 5 183, including 2 072 people from plasma to blood and 3 111 people from blood to plasma, among which 2 671 (51.5%) were men and 3 632 (70.1%) were over 50 years old, with significant differences in gender (P<0.05) and age (P<0.001). 【Conclusion】 There were a small number of donors donating both blood and plasma in Jiange and Cangxi, and men aged 40 to 50 were the majority, and people over 50 years old were more likely to shift the donation goals. The vast majority of donors have a single and fixed donation goal (blood or plasma), and are not easy to change.
RESUMO
The highly contagious SARS-CoV-2 and its associated disease (COVID-19) are a threat to global public health and economies. To develop effective treatments for COVID-19, we must understand the host cell types, cell states and regulators associated with infection and pathogenesis such as dysregulated transcription factors (TFs) and surface proteins, including signaling receptors. To link cell surface proteins with TFs, we recently developed SPaRTAN (Single-cell Proteomic and RNA-based Transcription factor Activity Network) by integrating parallel single-cell proteomic and transcriptomic data based on Cellular Indexing of Transcriptomes and Epitopes by sequencing (CITE-seq), which contains gene cis-regulatory information. We apply SPaRTAN to CITE-seq datasets from patients with varying degrees of COVID-19 severity and healthy controls to identify the associations between surface proteins and TFs in host immune cells. Here, we present COVID-19db of Immune Cell States (https://covid19db.streamlit.app/), a web server containing cell surface protein expression, SPaRTAN-inferred TF activities, and their associations with major host immune cell types. The data include four high-quality COVID-19 CITE-seq datasets with a toolset for user-friendly data analysis and visualization. We provide interactive surface protein and TF visualizations across major immune cell types for each dataset, allowing comparison between various patient severity groups for the discovery of potential therapeutic targets and diagnostic biomarkers.
RESUMO
【Objective】 The loss of iron stores is well documented in whole blood donors, and a large number of studies have confirmed that blood donors are at risk of iron deficiency. With the development of apheresis donation, more and more attention has been paid to the health of apheresis donors. However, little is known about the iron status of apheresis donors. In recent 10 years, iron status of apheresis donors has been studied at home and abroad, and iron deficiency was found common among them. There is no systematic study concerning apheresis donors iron deficiency at present. This article summarizes the literature, concerning the principles and preventive measures about iron deficiency in apheresis donors, and aims at improving the recruitment strategy and providing high-quality service for donors.
RESUMO
【Objective】 To evaluate the performance of electrochemiluminescence immunoassay (ECLIA) in detecting HIV antigen/antibody in blood screening. 【Methods】 A total of 128 donors, reactive to anti-HIV(ELISA)testing, from September 2016 to September 2020 were enrolled, and seven samples were reactive to double anti-HIV reagents, among which 6 were confirmed by WB, 1 confirmed by NAT as negative.Two group of donors, reactive to solo anti-HIV reagent but being confirmed negative by WB(n=121) vs.randomly selected donors non-reactive to ELISA + NAT(June to September 2020, n=1360), were subjected to HIV antigen/antibody testing using ECLIA to compare the testing results, including concordance rate, sensitivity and specificity. 【Results】 The ECLIA results remained non-reactive for 1360 samples initially non-reactive to both ELISA and NAT.The concordance rate of anti-HIV reactivity by ECLIA and ELISA+ WB were 100%(6/6). For 122 samples, reactive to ELISA anti-HIV testing but nonreactive to confirmatory testing, 4(3.28%)of them were reactive to HIV antigen/antibody testing and 118(96.72%) nonreactive, with the concordance rate of ECLIA and ELISA at 96.88%(124/128). The sensitivity, specificity and false positive rate of ECLIA and ELISA were 100% vs 100%, 99.73% vs 91.77%, and 0.27% vs 8.23%, respectively. 【Conclusion】 ECLIA for HIV antigen/antibody detection has good sensitivity and specificity, which can meet the requirements of blood screening, and the false positive rate is lower than that of ELISA, adopted commonly in blood bank at present.
RESUMO
Objective:To investigate the effect of thoracolumbar osteoporotic vertebral compression fracture (OVCF) combined with lumbar degenerative spondylolisthesis (LDS) on spinopelvic sagittal parameters in the elderly.Methods:A case-control study was conducted to analyze the clinical data of 77 patients with thoracolumbar OVCF admitted to Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from December 2016 to December 2021. There were 16 males and 61 females with the age of 61-92 years [(73.9±8.4)years]. All patients had single-level thoracolumbar fractures (T 11-L 2). Simple thoracolumbar OVCF was found in 49 patients (OVCF group) and thoracolumbar OVCF combined with LDS in 28 (OVCF+LDS group). The pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL), thoracic kyphosis (TK), thoracolumbar kyphosis (TLK), sagittal vertical axis (SVA) and Roussouly types were detected and compared between the two groups before operation. Results:There was no significant difference in PT and SVA between the two groups (all P>0.05). The PI, SS, LL, TK and TLK in OVCF+LDS group were (55.8±11.0)°, (34.1±10.9)°, (45.7±9.1)°, (35.7±6.1)° and (24.8±5.2)°, significantly larger than (47.9±8.8)°, (27.0±9.4)°, (33.1±7.9)°, (29.5±6.2)° and (18.4±5.5)° in OVCF group (all P<0.01). Roussouly types I-IV counted 22, 16, 5 and 6 patients in OVCF group, compared to 8, 5, 6 and 9 patients in OVCF+LDS group ( P<0.05). Conclusions:Elderly patients with thoracolumbar OVCF combined with LDS can significantly alter spinopelvic sagittal parameters, and LDS may aggravate the thoracolumbar kyphosis of OVCF. To avoid sagittal imbalance, surgery should be performed as soon as possible.
RESUMO
From April to November 2019, 5 community health service centers in Shanghai Hongkou District were randomly selected for thematic group interviews to investigate the current status, problems and challenge for further development of chronic disease management. The community chronic disease management was mainly divided into growth period (typically hypertension and diabetes) and introduction period (cardiovascular and cerebrovascular diseases, respiratory diseases, dementia, osteoporosis). The management of hypertension and diabetes in the growing stage mainly faced difficulties such as refusal or non-cooperation of patients, loss of follow-up, incomplete quality control, not meeting quality control indicators, repeated management of comorbidities, insufficient information sharing, and discrepancy in assessment indicators of multiple parties. The management of cardiovascular and cerebrovascular diseases, respiratory diseases and other diseases in the introduction period mainly faced poor awareness rate of patients, loss of follow-up, difficulty in diagnosis, irregular medication, insufficient information sharing, lack of management plan, insufficient resource investment, and few variety of medicines in the community. The current management system should be refined to provide more effective and efficient chronic disease management in the community. Meanwhile, the awareness of residents, the information network and multi-center collaborative research also need to be strengthened.
RESUMO
Objective:To examine associations of sex hormone levels with bone turnover markers(BTMs) among men in the Northeast region of Henan Province.Methods:From December 2015 to March 2016, 707 male subjects were selected from a National Epidemiological Survey-2014(Thyroid Disorders, Iodine status and Diabetes, TIDE)research—Henan sub-center survey by using multistage stratified cluster random sampling. Fasting venous blood was collected to determine the levels of luteinizing hormone(LH), follicle stimulating hormone(FSH), estradiol(E 2), testosterone(T), dehydroepiandrosterone-sulfate (DHEAS), androstenedione(AD), sex hormone binding globulin(SHBG), dihydrotestosterone(DHT), free testosterone(FT), osteocalcin(OC), pro-collagen type 1 N-terminal propeptide(PINP), C-terminal-cross-linking telopeptide of type 1 collagen(β-CTX), 25-hydroxyvitamin D [25(OH)D], and parathyroid hormone(PTH). Results:A total of 697 men with an average age of(46.6±15.9)years were included in the study. Pearson correlation analysis showed that age was positively associated with LH, FSH, T, and SHBG, while negatively associated with E 2, DHEAS, AD, FT, β-CTX, OC, and PINP, without significant correlation with DHT, 25(OH)D, and PTH. Pearson correlation analysis and linear regression analysis showed that E 2 was negatively associated with β-CTX; T was positively associated with OC, FSH was negatively associated with OC; LH, FSH, and SHBG were negatively associated with PINP; E 2, T, FT, DHT, and AD were positively associated with PINP. After adjusting for age and BMI, linear regression analysis showed that T was still significantly positively associated with OC and PINP, with 0.302 ng/ml and 0.015 ng/ml increasing for OC and PINP every 1 ng/ml increase in T; E 2 and DHT were positively associated with PINP, with 0.250 and 0.047 ng/ml increasing for PINP every 1 pg/ml increase in E 2 and DHT. Conclusions:Age is an important factor influencing sex hormones and BTMs. Serum levels of T, E 2, and DHT are associated with bone formation and bone absorption markers.
RESUMO
Objective:To evaluate the optimized effect of infiltration between the popliteal artery and the capsule of the knee (IPACK)-adductor canal block (ACB) combined with general anesthesia when used for the total knee arthroplasty.Methods:Sixty patients of both sexes, aged 18-64 yr, with body mass index of 18-24 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective unilateral total knee arthroplasty, were divided into 2 groups ( n=30 each) using a random number table method: IPACK-ACB combined with general anesthesia group (group IA) and conventional anesthesia femoral nerve block-popliteal superior sciatic nerve block combined with general anesthesia group (group C). Before induction of general anaesthesia, 0.375% ropivacaine 15 ml was injected for IPACK and 0.375% ropivacaine 25 ml for ACB under the ultrasound guidance in group IA, femoral nerve block and popliteal superior sciatic nerve block was performed under the guidance of ultrasound combined with a nerve stimulator and 0.375% ropivacaine 20 ml was injected in group C. After confirming the efficacy of nerve block, total intravenous anesthesia was carried out to maintain bispectral index values at 40-60.Patient-controlled intravenous analgesia was performed with sufentanil after operation, and the visual analog scale score was maintained ≤ 3.The quadriceps muscle strength score was recorded when discharge from postanesthesia care unit and at 24, 48 and 72 h after surgery.The first postoperative off-bed time and development of foot drop in awake patients after surgery, requirement for rescue analgesia and adverse reactions were recorded.The postoperative length of hospital stay and score for patients′ satisfaction with postoperative recovery were also recorded. Results:Compared with group C, the postoperative quadriceps muscle strength scores and score for patients′ satisfaction with postoperative recovery were significantly increased, the incidence of postoperative foot drop was decreased, and the length of hospital stay and first postoperative off-bed time were shortened in group IA ( P<0.05). Conclusion:IPACK-ACB combined with general anesthesia may be an optimized strategy which is helpful for outcomes after total knee arthroplasty.

RESUMO
Objective To investigate the early stage clinical outcomes of reconstruction of the anterior cruciate ligament with functional eccentric fixation. Methods We retrospective reviewed the 35 patients with anterior cruciate ligament reconstruc?tion from autologous hamstring tendon from April 2015 to March 2017. The humeral were fixed with interference screws and divid?ed into two groups according to different fixation methods. The group I was fixed with functional eccentric interference screw, in?cluding a total of 16 cases (9 males and 7 females, mean age 26.8 years). The group II was fixed with anatomical foot print central fixation screw, including a total of 19 cases (11 males and 8 female, mean age 27.6 years). Lysholm scores were recorded before and 1 year postoperatively in group I and group II. Gait analysis of knee flexion and extension, varus and valgus, internal and exter?nal rotation angle, and the MRI was performed at 1 year after surgery to observe the clinical effects. Results The Lysholm score of the functional eccentric fixed group increased from preoperative 58.5±5.5 points to 87.5±4.5 points with statistically significant difference (t=18.532, P=0.014). The foot print central fixed group increased from preoperative 57.0±6.5 points to 89.0±5.0 points with statistically significant difference (t=19.213, P=0.012). There was no significant difference between the eccentric fixed group and the foot print central fixed group in postoperative function (t=0.968, P=0.067). In gait analysis, the maximum flexion angle of the knee joint was increased from 51.8°±4.5°to 61.4°±3.5°before operation in functional eccentric group (t=8.532, P<0.001). The average mid?standing angle in eccentricity group (3.8°±2.1°) was lower than that in the foot center group (8.5°±2.8°) (t=8.716, P<0.001). There was no significant difference in the angle of internal and external valgus between the functional eccentricity group (8.6°±5.8°) and the fixed position of the foot print group (5.4°±5.2°) (t=0.382, P=0.844). The average mid?standing external rota? tion angle of the functional eccentric group was reduced from preoperative 10.5°±6.8°to postoperative-2.3°±4.1°(t=7.987, P<0.001). There was no significant difference in the average mid?standing external rotation angle of the standing phase in the postop?erative functional eccentricity group (-2.3°±4.1°) comparing with that of the foot center group (-2.1°±4.8°) (t=0.628, P=0.581). Conclusion Arthroscopic reconstruction of ACL with functional eccentric can effectively restore the function and kinematic char?acteristics of the knee joint.
RESUMO
Objective To retrospectively analyze the implementation of the antimicrobial agents prescription monthly review at the emergency and outpatient departments for the past five years, for evaluation of its action in promoting rational application of antimicrobial drugs. Methods At the baseline investigation stage, 1780 prescriptions on antibiotics in emergency and outpatient department from June 2012 to November 2012 were randomly selected for centralized evaluation. The period of correction and observation falls into two stages. The first stage ranged from December 2012 to February 2015, when the prescription of antibiotics was sampled manually for monthly review. The second stage ranged from March 2015 to June 2017, when a prescription review software for prescription comment was introduced for the sample purpose. The data so acquired were subject to chi-square test and linear regression analysis using Excel 2010 and SPSS 16. 0. Results The rational rate of prescription for antibiotics at the emergency department increased from 80. 56％ of the baseline stage to 99. 47％ of the second stage (166506/167400), scoring a difference of statistical significance (P<0. 001). With intervention of the prescription review software, the percentage of irrational use of antimicrobial agents dropped by 5. 18％ compared to the baseline stage. Conclusions Monthly prescription review on antimicrobial agents at the outpatient and emergency departments could promote the rational use of antimicrobial agents and play an important role in clinical drug safety. Information system and performance assessment contributed to the effect of prescription review.

Objective To investigate the clinical efficacy of posterior short-segment pedicle screw fixation combined with vertebroplasty or injured vertebral transpedicular fixation in the treatment of osteoporotic thoracolumbar Magerl type A3 fractures.Methods A retrospective case control study was conducted on 39 patients with acute traumatic osteoporotic thoracolumbar burst fractures admitted from May 2007 to May 2016.There were 17 males and 22 females,aged 52-85 years (mean 61.3 years).All patients had single segment thoracolumbar fracture(T11-L2),with bone mineral density T value ＜-2.5 SD and the Frankel grade D or E.According to operation method,the patients were divided into Group A (n =22) which adopted short segment pedicle screw fixation combined with vertebroplasty and Group B (n =17) which adopted pedicle screw fixation combined with injured vertebra transpedicular fixation.The operation time and blood loss were compared between the two groups.VAS and Frankel grade were used to evaluate the patients' pain and the recovery of neurological function.The height recovery and Cobb angle of fracture vertebra were measured according to X-ray.Complications at follow ups were observed.Results All patients underwent the operations successfully with good healing.The mean follow-up time was 23.5 months (range,12-40 months).The operation time was (61.7 ± 6.7)minutes in Group A and (48.1 ± 7.5) minutes in Group B (P ＜ 0.05).The blood loss was (347.7 ± 44.9) ml in Group A and (288.3 ±41.6)ml in Group B (P ＜ 0.05).Postoperative VAS score and VAS at the final follow-up in both groups were significantly improved compared with those before operation (P ＜ 0.05),with no significant difference between the two groups.Four cases in Group A and two cases in Group B with Frankel grade D were classified as grade E.After operation,the recovery rate of injured vertebral Cobb angle and anterior height were significantly improved in both groups (P ＜ 0.05).The recovery rate of Cobb angle and anterior height at the last follow up was lower than that after surgery,but with no statistical difference (P ＞ 0.05),and no significant differences were found between the two groups either (P ＞ 0.05).The screws were removed from four patients in Group A and two patients in Group B.No complications or failure of internal fixation was found during follow-up.Conclusion Posterior shortsegment pedicle screw fixation combined with vertebroplasty or injured vertebra transpedicular fixation are both helpful to the height recovery of vertebral osteoporotic fractures and reduce kyphosis with similar efficacy,while the former has the advantages of shorter operation time and less bleeding.
RESUMO
<p><b>OBJECTIVE</b>To study the regulating effect of thyroid pathway on electroacupuncture (EA) for mammary gland hyperplasia (MGH) so as to provide new research ideas for the mechanism of EA for MGH and to provide the evidence for clinical application.</p><p><b>METHODS</b>Sixty adult female SD rats were randomly divided into a blank group, a model group, an EA group, an EA with thyroidectomy group, an EA with sham operation group, 12 rats in each one. Except the blank group, the MGH model was established. Thyroid ablation was performed in the EA with thyroidectomy group, and sham operation was used in the EA with sham operation group, exposing thyroid without excision, 1 day after model establishment. EA was applied in the EA, the EA with thyroidectomy, and the EA with sham operation groups on the 4th day after model establishment, and not used in the other groups, but catching, routine disinfection and fixation were all the same as the above groups. The acupoints in the group A were bilateral "Tianzong" (SI 11), "Ganshu" (BL 18) and "Zusanli" (ST 36); and those in the group B were bilateral "Wuyi" (ST 15), "Hegu" (LI 4) and "Danzhong" (CV 17). The two groups of points were alternately used. EA, continuous wave, 2 Hz and 1 mA, was connected at "Tianzong" (SI 11) and "Ganshu" (BL 18), "Wuyi" (ST 15) and "Hegu" (LI 4) at the same side, 2 pairs EA a time, 20 min a time, once a day. All the intervention was given for 4 courses, 5 times as 1 course with 2 days between courses. After intervention, the height and diameter of the rat papilla were measured. Estrogen (E) and progestational hormone (P) in the serum were detected by enzyme linked immunosorbent assay (ELISA), and the contents and protein expression of estrogen receptor α (ERα) and progesterone receptor (PR) in the mammary glands were detected by immunofluorescence and Western-blot.</p><p><b>RESULTS</b>(1) The height and diameter of papilla in the model group increased compared with those in the blank group (both <0.01). The height and diameter of papilla in the EA, EA with sham operation groups reduced compared with those in the model group (all <0.01). Those in the EA with thyroidectomy group were lower than those in the model group, without statistical significance (both >0.05). (2) Compared with the blank group, E increased and P decreased in the model group (both <0.01). Compared with the model group, E decreased and P increased in the EA and EA with sham operation groups (all <0.01). The contents of E and P had no statistical significance between the model and the EA with thyroidectomy groups (both >0.05). (3) Compared with the blank group, the ERα content and protein expression increased and the PR content and protein expression decreased in the model group (all <0.01). Compared with the model group, the ERα content and protein expression decreased and the PR content and protein expression increased in the EA and EA with sham operation groups (all <0.01). The ERα and PR content and protein expression had no statistical significance between the model and the EA with thyroidectomy groups (all >0.05).</p><p><b>CONCLUSION</b>The effect of EA for MGH may be closely related to the regulation of thyroid.</p>
