Acupotomy therapy demonstrates the definite clinical efficacy on knee osteoarthritis (KOA). After reviewing systematically the mechanism studies on acupotomy for KOA over the past 5 years, It is revealed that acupotomy synergistically intervenes in the pathological progression of KOA through multi-target approaches, such as regulating cartilage homeostasis, restoring skeletal muscle function, alleviating synovial inflammatory responses, remodeling subchondral bone, and neuromodulation. But the current research still limits to single-tissue phenotypic observation, and is insufficiency in the in-depth exploration of multi-tissue synergistic interactions and molecular upstream-downstream regulatory mechanisms. Future studies should focus on the inheritance and innovation of acupotomy theory, and integrating multi-omics analytical technologies, artificial intelligence, and novel biochemical detection methods. The mechanism research targets on the interaction mechanisms among tissues, direct effects of acupotomy, immune-inflammatory regulatory mechanisms, and analgesic mechanisms, so as to comprehensively elucidate the therapeutic mechanism of acupotomy for KOA.

OBJECTIVE: To study incident and clinical characteristics of the coronary microcirculation dysfunction (CMD) in patients with acute myocardial infarction (AMI) after percutaneous coronary intervention (PCI) by myocardial contrast echocardiography (MCE) and to explore the predictive value of CMD for in-hospital acute heart failure event. METHODS: One hundred and forty five patients with AMI who had received PCI and completed MCE during hospitalization in Peking University People' s Hospital from November 2015 to July 2021 were enrolled in our study. The patients were divided into CMD group and normal group according to the coronary microcirculation status detected by MCE. Clinical data and MCE data of the two groups were collected and analyzed. The acute heart failure event during hospitalization was described. A multivariate Logistic regression model was built to analyze the risk of acute heart failure in patients with CMD. A receiver operating characteristic (ROC) curve was drawn to evaluate the value of CMD in predicting acute heart failure event. RESULTS: CMD detected by MCE occurred in 87 patients (60%). Compared with normal group, patients with CMD had higher troponin I (TnI) peak level [52.8 (8.1, 84.0) μg/L vs. 18.9 (5.7, 56.1) μg/L, P=0.005], poorer Killip grade on admission (P=0.030), different culprit vessel (P < 0.001) and more patients had thrombolysis in myocardial infarction (TIMI) flow pre-PCI less than grade 3 in culprit vessel (65.1% vs. 43.1%, P=0.025). Meanwhile, patients with CMD had poorer left ventricular ejection fraction (LVEF) [52% (43%, 58%) vs. 61% (54%, 66%)], poorer global longitudinal strain (GLS) [-11.2% (-8.7%, -14.0%) vs.-13.9% (-10.8%, -17.0%)] and worse wall motion score index (WMSI) (1.58±0.36 vs. 1.25± 0.24) (P all < 0.001). Acute left heart failure happened in 13.8% of the CMD patients, which were significant higher than that in the patients with normal coronary microcirculation perfusion (1.7%, P=0.013). After correcting for the culprit vessel, the TIMI flow pre-PCI in the culprit vessel and the peak TnI value, the risk of acute left heart failure in the patients with CMD was still high (OR=9.120, 95%CI: 1.152-72.192, P=0.036). The area under ROC curve (AUC) was 0.677 (95%CI: 0.551-0.804, P=0.035). CONCLUSION The incidence of CMD detected by MCE in patients with AMI post-PCI was 60%. Patients with CMD have a higher risk of acute left heart failure during hospitalization.

Objective:To explore the role of clinical pharmacists participating in the management of prophylactic antibiotics during the perioperative period of thoracic surgery, and to evaluate the effects after participating in the practice.Methods:The use of antimicrobials during the perioperative period of thoracic surgery in Wenjiang Hospital of Sichuan Provincial People's Hospital in August 2019 (pre-practice) was retrospectively analyzed. The existing problems were summarized, and the possible causes of the existing problems were analyzed. The improvement measures were jointly developed by clinical pharmacists and physicians. Clinical pharmacists continued to manage the use of antimicrobials by means of medication order reviews, ward rounds for pharmacy service, and medication training. The use of prophylactic antibiotics during the perioperative period of thoracic surgery was compared between August 2019 (pre-practice group) and December 2019 (post-practice group) and the practical effect was evaluated.Results:Clinical pharmacists reviewed perioperative patients' medication orders once a day, ward rounds for pharmacy service twice a week, and medication training once a month. Twenty-two patients were enrolled before practice, and 26 patients were enrolled after practice. There were no significant differences in age, sex, body weight, operative time, type of surgical incision, and preventive use of antibiotics between the two groups (all P > 0.05). In the post-practice group, the appropriate time for preoperative administration was 100.0%, which was significantly higher than 88.2% in the pre-practice group. The reasonable rate of preoperative preventive drug selection was 100.0%, which was significantly higher than 44.4% in the pre-practice group ( χ2 = 17.50, P < 0.001). In the post-practice group, the duration of preventive medication was (1.82 ± 0.59) days, which was significantly shorter than (7.54 ± 3.25) days in the pre-practice group ( t = 11.97, P < 0.001). In the post-practice group, the cost of antibacterial drugs was 316.00(237.00,454.25) yuan, which was significantly lower than 1 136.00(391.81 , 2 184.65) yuan in the pre-practice group ( Z = -2.78, P < 0.05). The defined daily dose of antibiotics among inpatients was 2.67(2.00,3.42), which was significantly lower than 8.88(3.92 , 19.18) in the pre-practice group ( Z = -3.26, P < 0.05). There were no significant differences in the incidence of postoperative pulmonary infection and total length of hospital stay between the two groups (both P > 0.05). Conclusion:Clinical pharmacists participating in the management practice of perioperative prophylactic antibiotics in thoracic surgery can effectively promote the rational application of perioperative antibiotics, markedly improve the reasonable rate of prophylactic drug delivery, shorten the course of prophylactic drugs, reduce the cost of antibiotics, decrease the defined daily dose of antibiotics, without increasing the risk of postoperative pulmonary infection and the total length of hospital stay.

Objective: This study aimed to evaluate the role of preoperative two-dimensional (2D) shear wave elastography (SWE) in assessing the stages of liver fibrosis in patients with suspected biliary atresia (BA) and compared its diagnostic performance with those of serum fibrosis biomarkers. Materials and Methods: This study was approved by the ethical committee, and written informed parental consent was obtained. Two hundred and sixteen patients were prospectively enrolled between January 2012 and October 2018. The 2D SWE measurements of 69 patients have been previously reported. 2D SWE measurements, serum fibrosis biomarkers, including fibrotic markers and biochemical test results, and liver histology parameters were obtained. 2D SWE values, serum biomarkers including, aspartate aminotransferase to platelet ratio index (APRi), and other serum fibrotic markers were correlated with the stages of liver fibrosis by METAVIR. Receiver operating characteristic (ROC) curves and area under the ROC (AUROC) curve analyses were used. Results: The correlation coefficient of 2D SWE value in correlation with the stages of liver fibrosis was 0.789 (p < 0.001). The cut-off values of 2D SWE were calculated as 9.1 kPa for F1, 11.6 kPa for F2, 13.0 kPa for F3, and 15.7 kPa for F4. The AUROCs of 2D SWE in the determination of the stages of liver fibrosis ranged from 0.869 to 0.941. The sensitivity and negative predictive value of 2D SWE in the diagnosis of ≥ F3 was 93.4% and 96.0%, respectively. The diagnostic performance of 2D SWE was superior to that of APRi and other serum fibrotic markers in predicting severe fibrosis and cirrhosis (all p < 0.005) and other serum biomarkers. Multivariate analysis showed that the 2D SWE value was the only statistically significant parameter for predicting liver fibrosis. Conclusion 2D SWE is a more effective non-invasive tool for predicting the stage of liver fibrosis in patients with suspected BA, compared with serum fibrosis biomarkers.

Objective:To survey the influencing factors for depression based on path model analysis in late pregnant women, and to explore the interrelationships for depression.Methods:This cross-sectional study was conducted from January 2018 to March 2019.Antenatal women who came for a routine check-up at the antenatal clinic were invited to participate in the study.Collecting general information of pregnant women(including biological, psychological, social and other factors). The Hospital Anxiety and Depression Scale (HADS) was used to evaluate the incidence of depression during pregnancy.The differences between depression group and non-depression group were compared by SPSS 24.0, and the path analysis model was conducted by AMOS 21.0 to explore the influencing factors and interrelations of depression during pregnancy.Results:A total of 1 059 pregnant women completed questionnaire.The incidence of depression depression in third trimester women was 11.1%(118/1 059). The path model fitting well with the sample data(GFI=0.912, AGFI=0.901, RFI=0.920, CFI=0.931, RMSEA=0.033). Anxiety, psychological preparation for the current pregnancy, and level of education had both direct and indirect effects on depression in third trimester women(the total effects of the three factors were 0.381, -0.140 and -0.156, respectively). Sleep quality and family member with whom the pregnant women living during pregnancy had only direct effects (the effects were 0.136 and 0.107, respectively). Residence, monthly income of family and social support had only an indirect influence on depression(the effects were 0.175, 0.103, and 0.102, respectively).Conclusion:Path model analysis suggests that the residence, monthly income of family, family member with whom the pregnant women living during pregnancy and educational level are not easy to change. It is suggested the incidence of depression is reduced by intervening the pregnancy anxiety, social support, sleep quality and the psychological preparation for pregnancy.

Objective:To investigate the effect of cluster protection measures on postoperative infection in elderly lumbar disc herniation patients undergoing minimally invasive surgery by using intervertebral foramen mirror surgery.Methods:A total of 98 elderly lumbar disc herniation patients treated with the surgery in our hospital were enrolled from January 2018 to December 2019.They were randomized into the intervention group(n=49)receiving cluster protection measures and the routine group(n=49)receiving conventional protection measures.The incidences of infection and related indexes after surgery were compared between the two groups.Results:A total infection rate was higher in the routine group [16.33%(8/49)]than in the intervention group [4.08%(2/49)]( χ2=4.009, P=0.045). The operation time, out-of-bed activity time, hospitalization days and surgical blood loss were less in the intervention group than in the routine group[(30.4±1.1) min vs.(101.9±51.1) min, (1.6±0.7) d vs.(3.7±1.2) d, (4.3±0.6) d vs.(13.2±3.8) d, (54.8±7.3) ml vs.(142.7±69.6) ml, t=9.759, 10.193, 15.789 and 8.780, all P=0.000]. Conclusions:Compared with the routine prevention measures, the cluster prevention measures can ensure the perioperative safety, shorten the operation time and reduce surgical blood loss, out-of-bed activity time and hospitalization days.Therefore, after careful perioperative treatment and protection, the cluster prevention measures can relieve pain, restore function, reduce the incidences of postoperative infection and complications, and achieve satisfactory nursing results.

Objective To explore the effect of emergency nursing combined with predictive rehabilitation nursing on rehabilitation and prognosis of patients with acute stroke. Methods One hundred and thirty patients with acute stroke admitted to Zhejiang Hospital from June 2017 to December 2018 were enrolled, and they were divided into an emergency nursing group and a combined nursing group according to different nursing methods, 65 cases in each group. The emergency nursing group was given emergency nursing; and the combined nursing group was given emergency nursing combined with predictive rehabilitation nursing. After 2 weeks, the clinical efficacy was evaluated. The neurological function, motor ability, cognitive function, activities of daily living, clinical efficacy and the incidence of complications were observed in the two groups. Results After treatment, the scores of American National Institutes of Health Stroke Scale (NIHSS) in two groups was significantly lower than that before treatment, the scores of simple Fugl-Meyer motor function (FMA) and simple intelligent mental state examination scale (MMSE), Barthel index (BI) were obviously higher than those before treatment, and the changes of the above indexes in the combined nursing group were more significant than those in the emergency nursing group after treatment (NIHSS score: 13.68±4.01 vs. 19.47±3.82, FMA score: 31.65±4.11 vs. 26.47±4.53, MMSE: 25.34±3.71 vs. 20.07±3.08, BI: 54.68±7.01 vs. 47.37±6.51), the differences were statistically significant (all P < 0.05). The total effective rate of the combined nursing group was significantly higher than that of the emergency nursing group [90.77% (59/65) vs. 75.39% (49/65), P < 0.05], and the incidence of complications in the combined nursing group was obviously lower than that in the emergency nursing group [21.51% (14/65) vs. 40.00% (26/65), P < 0.05]. Conclusion The emergency nursing combined with predictive rehabilitation nursing has good clinical effect on patients with acute stroke, it can effectively elevate the neurological function, motor ability, cognitive function and daily living ability, improve blood lipid and coagulation function indicators, reduce the incidence of complications, facilitate rehabilitation and improve prognosis.

Objective To study the clinical manifestations and antibiotic sensitivity features of early-and late-onset invasive infections caused by group B Streptococcus (GBS). Methods A total of 96 infants with invasive GBS infections were enrolled prospectively from seven tertiary hospitals of GBS Infection Research Cooperative Group in southwest Fujian, such as Xiamen Maternal and Child Care Hospital, etc., from January 2016 to June 2018. According to the onset time of infection after birth, they were divided into early-onset GBS disease (GBS-EOD) group (<7 d, n=67) and the late-onset GBS disease (GBS-LOD) group (7-89 d, n=29). Clinical manifestations, disease spectrum, complications and outcomes of the two groups were compared. Drug sensitivity test was carried out using disk diffusion test. Chi-square or Fisher's exact test, two independent sample t-test or Mann-Whitney U tests were used for statistical analysis. Results (1) The average ages at onset in GBS-EOD and GBS-LOD groups were (15.8±6.7) h (0.5-142.0 h) and (25.0±8.1) d (9-89 d), respectively. The incidence of tachypnea, pallor, fever and convulsion were noted in 68.7% (46/67) vs 44.8% (13/29), 52.2% (35/67) vs 17.2% (5/29), 23.9% (16/67) vs 65.5% (19/29) and 7.5% (5/67) vs 48.3% (14/29) of GBS-EOD and GBS-LOD groups with χ2 values of 6.282, 10.199, 15.146 and 21.237 (all P<0.05). The main clinical manifestations of GBS-EOD were tachypnea and pallor, while most of the patients in the GBS-LOD group developed fever and convulsions. (2) The incidence of pneumonia, sepsis, meningitis, sepsis complicated by septic joints, pneumonia complicated by sepsis, sepsis complicated by meningitis and pneumonia complicated by sepsis and meningitis were noted in 43.3% (29/67) vs 20.7% (6/29), 9.0% (6/67) vs 17.2% (5/29), 0.0% (0/67) vs 3.4% (1/29), 0.0% (0/67) vs 6.9% (2/29), 31.3% (21/67) vs 13.8% (4/29), 6.0% (4/67) vs 31.0% (9/29) and 10.4% (7/67) vs 6.9% (2/29) of GBS-EOD and GBS-LOD groups. There was a statistically significant difference in the disease spectrum between the two groups (Fisher's exact test, all P<0.001). Compared with the GBS-LOD group, the GBS-EOD group had a higher incidence of pneumonia [85.1% (57/67) vs 41.4% (12/29), χ2=19.116, P<0.001] and a lower incidence of meningitis [16.4% (11/67) vs 41.4% (12/29), χ2=6.922, P=0.009]. Complications such as acute respiratory distress syndrome (ARDS), pulmonary hemorrhage, shock and persistent pulmonary hypertension of the newborn (PPHN) occurred much more in the GBS-EOD group than the GBS-LOD group [28.4% (19/67) vs 6.9% (2/29), 13.4% (9/67) vs 0.0% (0/29), 11.9% (8/67) vs 10.3% (3/29), 4.5% (3/67) vs 0.0% (0/29), χ2=13.683, P<0.001]. (3) Among the 96 patients, 23 (24.0%) had meningitis and 73 (76.0%) developed pneumonia and sepsis. Meningitis resulted in a higher fatality rate [17.4% (4/23) vs 4.1% (3/73), χ2=4.564, P=0.035] and longer average hospital stay [(37.2±12.6) vs (14.1±5.3) d, t=7.831, P<0.001] than pneumonia and sepsis. Seven out of the 19 meningitis survivors developed intracranial complications. (4) The overall fatality rate in this study was 7.3% (7/96) and no significant difference was found between GBS-EOD and GBS-LOD group [7.5% (5/67) vs 6.9% (2/29), χ2=0.010, P=0.982]. Among the 67 GBS-EOD infants, 58 (86.6%) occurred within 24 h and five of them died, but no death was reported in the other nine cases occurred after 24 h. (5) Totally 96 strains of GBS were isolated with 100% sensitivity to penicillin, ampicillin, cefazolin and meropenem, and 97% to vancomycin. Around 79.3%-91.0% of GBS isolates were resistant to clindamycin and erythromycin. Conclusions Clinial features vary greatly in GBS-LOD and GBS-EOD cases. Infants with meningitis have poor prognosis. The drug resistance rate of GBS to erythromycin and clindamycin are relatively high.
