ObjectiveTo observe ovarian microvascular damage in rats with cold coagulation and blood stasis syndrome and to explore the mechanism by which Liangfang Wenjing decoction improves this condition in rats. MethodsFifty SPF female SD rats were randomly divided into a blank group， a model group， low-dose （8.1 g·kg^-1） and high-dose groups （16.2 g·kg^-1） of Liangfang Wenjing decoction， and a 4-phenylbutyric acid （0.1 g·kg^-1） group， with 10 rats in each group. The ice-water bath method was employed to establish the rat model of cold coagulation and blood stasis syndrome. Concurrent with modeling， Liangfang Wenjing decoction was administered continuously for 21 days， once daily. The rats' syndrome manifestations and estrous cycles were recorded. The enzyme-linked immunosorbent assay （ELISA） was used to detect serum reproductive hormone levels and levels of endothelin-1 （ET-1）， nitric oxide （NO）， thrombomodulin （TM）， and von Willebrand factor （vWF） in ovarian tissue. Prothrombin time （PT）， activated partial thromboplastin time （APTT）， thrombin time （TT）， and fibrinogen （FIB） were measured. The ovarian microcirculatory blood perfusion was detected by laser speckle contrast imaging. Hematoxylin-eosin （HE） staining was performed to observe the ovarian histopathology， flow cytometry to detect ovarian apoptosis rate， and transmission electron microscopy to observe the ultrastructure of ovarian microvascular endothelial cells. Western blot was employed to detect the protein expression of endothelial nitric oxide synthase （eNOS）， phosphorylated eNOS （p-eNOS）， Caspase-3， B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， glucose-regulated protein 78 （GRP78）， C/EBP homologous protein （CHOP）， inositol-requiring enzyme1α （IRE1α）， p-IRE1α， apoptosis signal-regulating kinase 1 （ASK1）， p-ASK1， c-Jun N-terminal kinase （JNK）， and p-JNK. Immunofluorescence was used to detect ovarian Bax and Bcl-2 expression in microvascular endothelial cells. ResultsCompared with the blank group， the model group showed signs of cold coagulation and blood stasis syndrome， prolonged estrus cycles， and reproductive hormone disorders. Histopathological results revealed a decrease in follicle counts at all stages and disorganized granulosa cell arrangement. Ovarian microcirculatory perfusion was significantly decreased （P<0.01）. PT， APTT， and TT were reduced （P<0.05， P<0.01）， while FIB levels were increased （P<0.05）. In ovarian tissue， NO content was decreased， while ET-1， vWF， and TM levels were increased significantly （P<0.01）. The apoptosis rate of ovarian cells was markedly increased （P<0.01）. Furthermore， p-eNOS/eNOS and Bcl-2 were decreased （P<0.05）， whereas Bax， cleaved-Caspase-3/Caspase-3， GRP78， CHOP， p-IRE1α/IRE1α， p-ASK1/ASK1， and p-JNK/JNK expression showed significant increases （P<0.05， P<0.01）. Compared with the model group， Liangfang Wenjing decoction intervention alleviated the symptoms of cold coagulation and blood stasis， gradually restored the estrus cycle， and improved ovarian histopathology and endothelial cell ultrastructure. Microcirculatory blood perfusion was significantly elevated （P<0.05）. NO content in ovarian tissue was elevated， while ET-1， vWF， and TM levels were significantly decreased （P<0.05， P<0.01）. The p-eNOS/eNOS ratio and Bcl-2 expression were significantly elevated （P<0.05）， while the expression of Bax， cleaved-Caspase-3/Caspase-3， GRP78， CHOP， p-IRE1α/IRE1α， p-ASK1/ASK1， and p-JNK/JNK was significantly decreased （P<0.05， P<0.01）. ConclusionLiangfang Wenjing decoction may regulate the IRE1α/ASK1/JNK signaling pathway to inhibit endoplasmic reticulum stress， attenuate apoptosis， and improve microvascular endothelial injury in ovaries of rats with cold coagulation and blood stasis syndrome.

Objective:To examine the prevention effecacy and safety of preprotein convertase subtilisin-kexin 9 (PCSK9) inhibitors in stroke in patients with atherosclerotic cardiovascular disease (ASCVD) at primary and secondary prevention.Methods:PubMed, Embase, Web of Science, Cochrane Library, and Wanfang and CNKI databases were searched for randomized controlled trials comparing evolocumab, alirocumab, tafolecimab or inclisiran (experimental group) with placebo or conventional therapy (control group) in hyperlipidemia and ASCVD from inception to March 2024. Valid data were extracted after screening and applying Cochrane Literature quality assessment tool to assess the literature quality. Efficacy outcome (incidences of stroke and ischemic stroke) and safety outcome (cardiovascular mortality, and incidences of aminotransferase increased by more than 3 times, creatine kinase increased by more than 3 times, allergic reaction and hemorrhagic stroke) were recorded. Meta analysis of the extracted data was conducted using Stata software to calculate the risk difference ( RD). Results:Twenty articles (21 randomized controlled trials) were included with 62 799 patients. For primary prevention, no significant difference was found between PCSK9 inhibitors and control groups in stroke incidence ( RD=0.000, 95% CI: -0.002-0.003, P=0.905) or ischemic stroke incidence ( RD=0.001, 95% CI: -0.005-0.006, P=0.824); incidence of creatine kinase increased by more than 3 times in the PCSK9 inhibitors group was significantly decreased compared with that in the control group ( RD=-0.005, 95% CI: -0.010-0.000, P=0.039). For secondary prevention, PCSK9 inhibitors group had significantly reduced stroke incidence ( RD=-0.004, 95% CI: -0.006--0.002, P<0.001) and ischemic stroke incidence ( RD=-0.003, 95% CI: -0.005--0.002, P<0.001) compared with control group; no significant differences in cardiovascular mortality, or incidences of aminotransferase increased by more than 3 times, creatine kinase increased by more than 3 times, allergic reaction and hemorrhagic stroke were noted between the PCSK9 inhibitors group and control group ( P>0.05). Conclusion:PCSK9 inhibitors in primary prevention have no significant effect on stroke or ischemic stroke incidences, but can decrease the incidence of creatine kinase increased by more than 3 times; PCSK9 inhibitors in secondary prevention can reduce stroke and ischemic stroke incidences without increasing complications and thus enjoying certain safety.

ObjectiveTo explore the longitudinal measurement invariance of standardized Constitution in Chinese Medicine Questionnaire （CCMQ） among Chinese adult populations， and to provide evidence for the longitudinal effect analysis of this questionnaire. MethodsA total of 509 adults who voluntarily received 26 weeks of comprehensive traditional Chinese medicine （TCM） constitution fitness intervention were included （3 time points： before intervention， 13 weeks intervention， and 26 weeks intervention）， evaluated by CCMQ with 9 subscales. A single-group confirmatory factor analysis was performed to establish a single-group baseline model with a well-fitting model， and then nested models， that is multiple groups of confirmatory factors analysis， are used to analyze the longitudinal measurement invariance， followed by configural invariance， metric invariance， scalar invariance， and strict invariance. Comparative Fit Index （CFI）， Root Mean Square Error of Approximation （RMSEA）， and Standardized Root Mean Square Residual （SRMR） were used as model fit indicators for the analysis. ResultsThe single-group confirmatory factors analysis proved that the 9 subscales of CCMQ fit well at the three time points （CFI： 0.933~0.992， RMSEA： 0.027~0.080， SRMR： 0.022~0.045）. The multiple-group confirmatory factors analysis showed that the configural， metric， scalar， and strict invariance across time of qi-stagnation and special diathesis constitution were established （ΔCFI＜0.01， ΔRMSEA＜0.01）； the configural， metric， scalar， and partial strict invariance across time of phlegm-dampness constitution subscale were established （ΔCFI＜0.01， ΔRMSEA＜0.01）； the configural， metric， partial scalar and partial strict invariance of 6 subscales， including gentleness， qi-deficiency， yang-deficiency， yin-deficiency， dampness-heat， and blood-stasis constitutions， were all established （ΔCFI＜0.01， ΔRMSEA＜0.01）. ConclusionThe CCMQ met at least metric invariance at 3 time points， which can be applied to the study of whether different time points have the same unit or meaning. The measurement invariance of the 3 subscales of phlegm-dampness， qi-stagnation and special diathesis， special diathesis have longitudinal measurement invariance， so the mean comparison over time could be made； while the 6 subscales of gentleness， qi-deficiency， yang-deficiency， yin-deficiency， dampness-heat， and blood-stasis constitutions meet partial scalar and partial strict invariance， which could be explained partially for the difference in the comparison of the mean over time.

Objective:To understand the epidemiology of rubella and the genetic characteristics of the virus circulating during the period 2021-2022, providing basic scientific data for rubella prevention and control in China.Methods:National rubella incidence data for the period 2021-2022 were obtained from the Infectious Disease Surveillance System module and the Surveillance Report Management module of the China′s Disease Prevention and Control Information System. Positive rubella virus(RuV)isolates were obtained from the National Measles/Rubella Laboratory Network. Two nucleotide (nt) fragments [F1-480 (8 633-9 112 nt) and F2-633 (8 945-9 577 nt)] located in the E1 gene were amplified and determined by reverse transcription polymerase chain reaction (RT-PCR), and the target gene (E1-739) was obtained after collating and splicing. The sequences obtained in this study were used to construct a phylogenetic tree with the reported reference strains for genotype and lineage identification. Additionally, the phylogenetic analysis was performed to assess their genetic relatedness of RuV strains prevalent in China during 2018-2020 from GenBank database.Results:In 2021-2022, the rubella incidence in China was 0.06/100, 000 (2021: 840 cases; 2022: 784 cases), with cases primarily concentrated in the western and southern provinces. Age distribution analysis showed that rubella cases in 2021-2022 was mainly in children under 5 years of age (2021: 34.17%, 287/840; 2022: 42.09%, 330/784), with the highest proportion in children aged 0-2 years. Further analysis of the immunization history of cases revealed that in the 8-23 months age group, a significant proportion of cases had received only one dose of rubella containing vaccine (RCV); cases in the 2-14 years age group were mainly among children who had received two or more doses of RCV; however, cases over 15 years of age were primarily found in individuals who had not received RCV or had unknown immunization history. National virological surveillance data showed that totally 22 RuV virus isolates were obtained, from 6 provinces in China during 2021-2022, which belonged to lineage 1E-L2 (11 strains) and 2B-L2c (11 strains). And these viruses displayed high genetic homology with RuV prevalent from 2018 to 2020.Conclusions:The incidence of rubella in China was maintained at a low level during 2021-2022, and the prevalent RuV strains were lineage 1E-L2 and 2B-L2c.

BACKGROUND: The KangDuo-Surgical Robot-01 (KD-SR-01) system is a new surgical robot recently developed in China. The aim of this study was to present our single-center experience and mid-term outcomes of urological procedures using the KD-SR-01 system. METHODS: From August 2020 to April 2023, consecutive urologic procedures were performed at Peking University First Hospital using the KD-SR-01 system. The clinical features, perioperative data, and follow-up outcomes were prospectively collected and analyzed. RESULTS: A total of 110 consecutive patients were recruited. Among these patients, 28 underwent partial nephrectomy (PN), 41 underwent urinary tract reconstruction (26 underwent pyeloplasty, 3 underwent ureteral reconstruction and 12 underwent ureterovesical reimplantation [UR]), and 41 underwent radical prostatectomy (RP). The median operative time for PN was 112.5 min, 157.0 min for pyeloplasty, 151.0 min for ureteral reconstruction, 142.5 min for UR, and 138.0 min for RP. The median intraoperative blood loss was 10 mL for PN, 10 mL for pyeloplasty, 30 mL for ureteral reconstruction, 20 mL for UR, and 50 mL for RP. All procedures were successfully completed without conversion, and there were no major complications in any patient. The median warm ischemia time of PN was 17.3 min, and positive surgical margin was not noted in any patient. The overall positive surgical margin rate of RP was 39% (16/41), and no biochemical recurrence was observed in any RP patient during the median follow-up of 11.0 months. The surgical success rates of pyeloplasty and UR were 96% (25/26) and 92% (11/12) during the median follow-up of 29.5 months and 11.5 months, respectively. CONCLUSION The KD-SR-01 system appears feasible, safe, and effective for most urological procedures, based on our single-center experience.

Objective:To explore the influence mechanism of frustration situation and attribution style on adolescents' implicit and explicit aggression under the framework of general aggression model.Methods:Using the multi-dimensional attribution scale, thirty adolescents with internal attribution and thirty with external attribution tendencies were selected as research objects.A mixed experimental design of 2(frustration vs no frustration) × 2(internal attribution vs external attribution)was adopted.And the frustration situation task, Buss-Perry aggressive questionnaire and single category implicit association test were used for the research.The experimental program of SC-IAT was rendered with E-prime 1.0.SPSS 17.0 software was used for descriptive statistics, double facter variance analysis, simple effect analysis and post-test. Results:The effects of frustration situation on individuals' explicit and implicit aggression were statistically significant ( F(1, 58)=6.78, P<0.05, η2 = 0.11 and F(1, 58)= 17.59, P<0.01, η2 = 0.23). The explicit aggression (83.43±15.05) and implicit aggression (-0.06±0.35) in the situation of frustration were higher than those in the condition of no frustration (80.54±12.40) and implicit aggression (-0.33±0.49). The effects of frustration situation on explicit and implicit aggression of subjects with different attribution styles were statistically significant ( F(1, 58)=4.90, P<0.05, η2 = 0.08 and F(1, 58)= 8.68, P<0.01, η2 =0.13). The frustration situation had a great influence on explicit aggression of the subjects with internal attribution ( D<0) (frustration: (82.90±12.98), no frustration: (77.56±10.16), while significant influence was observed on the implicit aggression of the subjects with external attribution ( D>0) (frustration: (0.07±0.35), no frustration: (-0.40±0.45)). Conclusion:Frustration situation influences explicit and implicit aggression of adolescents, and attribution style plays a moderating role in it.Both explicit aggression and implicit aggression can be explained by the general aggression model.

OBJECTIVE: To evaluate the efficacy of Wen-Luo-Tong Granules (WLT) local administration in the treatment of patients with peripheral neuropathy (PN) induced by chemotherapy or target therapy. METHODS: This study is a randomized, double-blinded, and placebo-controlled trial. Seventy-eight patients with PN induced by chemotherapy or target therapy were enrolled from China-Japan Friendship Hospital between July 2019 and January 2020. They were randomly assigned to WLT (39 cases) and control groups (39 cases) using a block randomization method. The WLT group received WLT (hand and foot bath) plus oral Mecobalamin for 1 week, while the control group received placebo plus oral Mecobalamin. The primary endpoint was PN grade evaluated by the National Cancer Institute-Common Toxicity Criteria for Adverse Events (NCI-CTCAE). The secondary endpoints included quantitative touch-detection threshold, neuropathy symptoms, Quality of Life Questionnaire-Chemotherapy Induced Peripheral Neuropathy (QLQ-CIPN20), and Quality of Life Questionnaire-Core30 (QLQ-C30). RESULTS: After treatment, the PN grade in the WLT group was significantly lower than that in the control group (1.00 ± 0.29 vs. 1.75 ± 0.68, P<0.01). The total effective rate in the WLT group was significantly higher than that in the control group (82.05% vs. 51.28%, P<0.01). Compared with the control group, the touch-detection thresholds at fingertips, neuropathy symptom score, QLQ-CIPN 20 (sensory scale, motor scale, autonomic scale, and sum score), and QLQ-C30 (physical functioning, role functioning, emotional functioning, and global health) in the WLT group significantly improved after treatment (P<0.01 or P<0.05). CONCLUSION WLT local administration was significantly effective in the treatment of patients with PN induced by chemotherapy or target therapy. (Trial registration No. ChiCTR1900023862).

Objective:To build the three different risk prediction models for peripherally inserted central catheter (PICC) -associated thrombosis based on machine learning algorithm, and compare the performance of the models, so as to provide a basis for evaluating and preventing PICC-associated thrombosis.Methods:The PICC-associated Thrombasis Risk Factor Questionnaire was developed based on the best evidence and expert consultation. From January 2016 to October 2020, convenience sampling was used to select 626 patients with PICC in the Affiliated Hospital of Jiangsu University as the research object to collect clinical data. Based on machine learning algorithms, Support Vector Machine (SVM) , XGBoost and Logistic regression methods were used to construct three different PICC-associated thrombosis risk prediction models, which were evaluated and compared.. Model evaluation indicators included Matthews correlation coefficient ( MCC) , F1 value, area under the receiver operating characteristic curve ( AUC) and Brier score. Results:A total of 30 variables were included, and the predictors included four aspects, namely, demographic data of patients, patient condition, treatment factors, and catheter-related factors. For the model verified on the test set, the Logistic regression prediction model had lower scores than the XGBoost and SVM prediction models in terms of MCC and F1 values. On AUC, the Logistic regression prediction model score was equal to SVM and smaller than XGBoost. On Brier, the Logistic regression prediction model scored higher than the XGBoost and SVM prediction models. Conclusions:The performance of the prediction model based on the machine learning algorithm XGBoost and SVM is superior to the traditional Logistic regression model in terms of sensitivity and accuracy. Thrombotic predictors can help guide medical and nursing staff to identify high-risk patients and reduce the incidence of PICC-associated thrombosis.
