ConclusionThe Evidence Grading Scale on Ancient classical prescriptions in Traditional Chinese medicine has good reliability and validity， which is practical for use in the development of TCM clinical guidelines and can better support clinical decision-making.

Objective:To investigate the effect of etomidate combined with transversus abdominis plane block (TAPB) on serum inflammatory factors and immune function indexes in patients after total hysterectomy.Methods:The study included 86 patients who underwent transabdominal total hysterectomy from Jan. 2020 to Jan. 2023. They were divided into group A (44 cases) and group B (42 cases) according to the random number table method. Group A received general anesthesia (propofol for anesthesia maintenance) + TAPB anesthesia, and group B received general anesthesia (propofol combined with etomidate for anesthesia maintenance) + TAPB anesthesia. The changes of heart rate (HR) and mean arterial pressure (MAP) at different time points were observed in the two groups. The serum related factors [interleukin-6 (IL-6) , tumor necrosis factor-α (TNF-α) ] and immune function indexes (T lymphocyte subsets CD3 +, CD4 +, CD4 +/CD8 +) were compared between the two groups before anesthesia and 24 h after operation. The complications of the two groups after anesthesia were counted. Results:HR and MAP of the two groups were gradually increased at T1 and T2 compared with those at T0, and gradually decreased at T3 and T4 compared with those at T2. The serum levels of IL-6 and TNF-α in the two groups at 24 h after operation were higher than those before anesthesia. The levels of IL-6 and TNF-α in group B were (261.17±33.67) ng/L and (12.37±2.57) ng/L, lower than those in group A (287.89±45.71) ng/L and (16.46±3.78) ng/L ( P<0.05) . The levels of CD3 +, CD4 + and CD4 +/CD8 + in the two groups were lower than those before anesthesia. The levels of CD3 +, CD4 + and CD4 +/CD8 + in group B were (65.26±4.67) %, (27.83±2.59) % and (1.48±0.35) , higher than those in group A (62.17±3.85) %, (26.25±2.16) % and (1.32±0.21) ( P<0.05) . There was no significant difference in the total incidence of complications after anesthesia between the two groups (13.64% in group A and 7.21% in group B) ( P>0.05) . Conclusions:The application of etomidate combined with TAPB anesthesia in total abdominal hysterectomy can inhibit the inflammatory response caused by surgical trauma, maintain the stability of postoperative immune function,without increasing the impact on hemodynamics of patients, or the incidence of complications.

Objective:To identify differentially expressed genes (DEGs) associated with the progression of synovitis in RA by using bioinformatics analysis and explore the effects of DMARDs such as methotrexate, tocilizumab and rituximab on the DEGs in RA synovium.Methods:RA expression profile microarray data GSE7307、GSE12021、GSE55457、GSE55235、GSE77298、GSE89408 were acquired from the public gene chip database (GEO), including 113 synovial tissue samples from RA and 70 healthy controls (HC). At the same time, synovial expression microarrays GSE45867, GSE24742 and GSE97165 after DMARDs treatment were obtained. These data included 8 samples treated with methotrexate, 12 treated with tocilizumab, 12 treated with rituximab and 19 treated with combined tDMARDs. R software was used to screen DEGs and Venn plots using gene ontology function enrichment and Kyoto encyclopedia of genes and genomes pathway enrichment analysis. Hub genes were selected by STRING online analysis tool and Cytoscape software.Results:Compared with HC, 797 DEGs were up-regulated and 434 DEGs were down-regulated in the synovial tissue of RA. These DEGs were mainly enriched in T cell activation, immune response-activating cell surface receptor signaling pathway. Using Cytoscape and cytoHubba to obtain 5 sets of DEGs based on the STRING database model, the degree algorithm screened out 10 hub genes: LCK, SYK, PTPRC, HLA-DRA, LYN, NCAPG, TOP2A, JUN, CXCR4, CCNB1. Methotrexate treatment significantly up-regulated 20 DEGs and down-regulated 30 DEGs. Rituximab treatment up-regulated 100 DEGs and down-regulated 55 DEGs. Tocilizumab treatment up-regulated 91 DEGs and down-regulated 317 DEGs. These altered DEGs were enriched in regulating cell adhesion, leukocyte-cell adhesion, leukocyte transfer, and insulin-like growth factor receptor signaling pathways. It was worth noting that after treatment, a total of 306 high-expressing DEGs were down-regulated, and 36 low-expressing DEGs were up-regulated.Conclusion:LCK, insulin-like growth factor receptor signaling pathway, etc. are the responsible molecular mechanisms and key pivot genes for the occurrence and development of RA, and the treatment of DMARDs, which are closely related to the response of RA to the treatment of DMARDs.

Objective:To investigate the changes in the morphology, structure and function of the bladders and their effects on the upper urinary tract dilatation(UUTD) after lumbosacral nerve transecting in rats.Methods:A total of 45 female SD rats were included, randomly divided into 3 groups with 15 rats in each group. Two groups were performed bilateral lumbar 6(L6) and cauda equina nerve shearing to establish neurogenic bladder(NB) model, which were nerve transected for 4 weeks(NB-4W) group and nerve transected for 12 weeks(NB-12W) group. Another group was performed bilateral L6 nerves and cauda equine exposing but not transecting, which was sham-operation (Sham) group. Cystometry and renal ultrasound examination were performed and rats in each group were killed to collect the kidney and bladder tissues in NB-4W group at 4 weeks, in Sham group and NB-12W group at 12 weeks after operation. HE, Masson staining, immunohistochemical staining and western blot were used to detect histological changes, expression of transforming growth factor-β1(TGF-β1) and α-smooth muscle actin(α-SMA).Results:All rats in NB-4W and NB-12W group showed acontractile detrusor. In the NB-4W and NB-12W group, the maximum cystometric capacity [(5.84±0.33) ml and (3.13±0.35) ml], the detrusor leak point pressure [(25.41±0.86) cm H 2O and (27.36±2.04) cm H 2O] (1 cm H 2O = 0.098 kPa), were significantly higher than those in the Sham group [(0.98±0.14) ml, (7.13±0.90) cm H 2O, both P<0.05]. Compliance in NB-4W group [(0.28±0.21) ml/cm H 2O] and NB-12W group [(0.17±0.12) ml/cm H 2O] were significantly lower than that of the Sham group [(0.34±0.26) ml/cm H 2O], and the compliance of NB-12W group was lower than that of NB-4W group significantly (all P<0.05). HE staining of the bladder showed that the inflammatory cell infiltration was obvious in the NB-4W and NB-12W group. Bladder collagen volume fractions in NB-4W group [(30.5±1.5) %] and NB-12W group [(45.2±3.8) %] were both higher than that of Sham group [(20.7±2.2) %, both P<0.05]. The expression of TGF-β1 and α-SMA in the bladder tissue of NB-4W group were higher than those of sham group, and that of NB-12W group were higher than NB-4W group. In NB-4W group and NB-12W group, 3 (20.0 %) and 7 (46.7 %) rats were found hydronephrosis, respectively. Additionally, HE staining showed that the degree of renal tubule injury and the number of inflammatory cell infiltration in the NB-4W and NB-12W group were higher than those in the Sham group. Masson staining showed that the volume fraction of collagen in kidneys of NB-4W and NB-12W group were (13.1±1.4) % and (21.6±1.9) %, respectively, which were significantly higher than that in sham operation group [(4.6±0.7) %, both P<0.05]. Conclusions:Bilateral L6 + cauda equina nerve transecting can induce NB with hydronephrosis in parts of rats. The degree of bladder fibrosis gradually increased with the time of nerve transection, and the incidence and severity of UUTD also increased with the time of nerve transection.

Objective:To analyze the characteristics of vocabulary and phrase acquisition in Mandarin-exposed children with autism spectrum disorder (ASD), intellectual developmental disability (IDD) or general developmental delay (GDD) in rehabilitation training institutions, and to provide a basis for selecting training vocabulary for ASD children.Methods:A cross-sectional study was carried out on 75 cases of 1-6-year-old children with neurodevelopmental disorders of ASD (the ASD group), IDD and GDD [the developmental disability(DD) group] by using a self-designed questionnaire containing nouns, verbs, adverbs, adjectives and pronouns, 464 words in total.The participants were recruited from Department of Rehabilitation Medicine, Beijing Shouer Liqiao Children′s Hospital and Beijing Shunyi District Shouer Yazhi Children′s Rehabilitation Center from March 2019 to February 2020.Effective co-mmunication vocabulary was obtained." Children Neuropsychological and Behavioral Scale, Revision 2016" was used for developmental evaluation.At the same time, 37 children with normal development and equivalent intellectual age [the typical development(TD) group] were recruited from the outpatient department of children′s Health Department of Children′s Hospital, Capital Institute of Pediatrics as a control group.The rank sum test or chi- square test was used for data analysis. Results:There were 31 children in the ASD group, with a median chronological age of 36.0 (27.0-59.0) months and median mental age of 20.6 (12.0-35.0) months.There were 44 children in the DD group, with a median chronological age of 37.0 (12.0-77.0) months and median mental age of 24.3 (6.0-56.0) months.There were 37 children in the TD group, with a median chronological age of 20.0 (10.0-61.0) months and median mental age of 21.9 (12.0-55.0) months.No significant difference was found in the mental age among the 3 groups ( χ2=0.718, P=0.698). The total development quotients of the ASD group and the DD group were 56 (36-83) and 68 (17-92), respectively, which were significantly lower than that of the TD group [99 (79-128)] ( χ2=45.234, 48.583; all P<0.001). Developmental assessment subscales: the developmental quotients of gross motor, fine motor, adaptive ability, language and social behavior as well as communication warning behavior indices in the ASD group were 77, 52, 60, 39, 52 and 40, respectively; the above scores in the DD group were 75, 64, 73, 60, 60 and 8, respectively.The developmental levels of the ASD group in all the above 6 aspects, except for the gross motor, were significantly lower than those of the DD group ( χ2=5.763, 5.172, 11.174, 6.108, 41.917; all P<0.05). The effective communication vocabulary was 10 in the ASD group, 174 in the DD group and 146 in the TD group, and the difference was significant ( χ2=12.785, P=0.002). The ratio of children that could speak phrases was 9.7%in the ASD group, 29.5%in the DD group, and 51.4% in the TD group.The difference was significant ( χ2=13.733, P=0.001). Based on the analysis of the effective communication vocabulary, the number of effective communication words was none in the ASD group, only 1 in the DD group and 49 in the TD group if taking that more than 75% of the children could speak the word as the statistical cut-off point.If taking that 50%-<75% of the children could speak the word as the cut-off point, the number of effective communication words was only 6 (Mama, Baibai, Baba, Baobao, Men, and Bu successively) in the ASD group, 187 in the DD group, and 71 in the TD group.If taking that 25%-<50% of the children could speak the word as the cut-off point, the number of effective communication words was 112, 183 and 103 in ASD, DD and TD groups, respectively.There was a statistically significant difference in the number of effective communication words among the three groups ( χ2=456.694, P<0.001). Matching the effective communication vocabulary that more than 25% of the children in the ASD group could speak with that that more than 50% of the children in the TD group could speak, there were 93 overlapping words, accounting for 78.8%(93/118) of the ASD group and 77.5%(93/120) of the TD group.In the overlapping words, nouns accounted for 67.7%(63/93) and verbs accounted for 26.9%(25/93). Conclusions:The vocabulary acquired by children with ASD and DD is similar to that by TD children of the same mental age.However, ASD children have extremely low vocabulary expression and comprehension ability.The effective communication words of ASD and TD children overlap at different percentages.These overlapping words provide a basis for optimizing the selection of training vocabulary.Training vocabulary dominated by nouns and verbs may help to improve the effect of intervention training in ASD children.

Objective:To explore the accuracy of intelligent calculation (IC) method for risk assessment of hospitalization for patients, aiming to build a more advantageous risk assessment system.Methods:The "Search Engine" program was developed based on hospital information system (HIS) of the Fifth Center Hospital in Tianjin, which automatically captured patient information and generated nutritional risk screening 2002 (NRS 2002) score, Caprini thrombosis risk assessment model and Padua thrombosis risk assessment model for venous thromboembolism (VTE), the CHA 2DS 2-VASc for predicting stroke risk stratification in atrial fibrillation and the HAS-BLED for predicting bleeding risk in anticoagulated patients with atrial fibrillation. A randomized controlled trial was conducted. According to the applicable conditions of each risk assessment, 100 risk scores from "Search Engine" program belonged to each risk assessment were randomly selected, defined as the IC group. Manual scoring with the data of the same case at the same time, defined as the traditional calculation (TC) group, compared the consistency of the scores and the difference in time-consuming between the two groups. Results:The Bland-Altman plots showed that the 95% limits of agreement (95% LoA) of NRS 2002 score, Caprini score, Padua score, CHA 2DS 2-VASc score and HAS-BLED score was -0.46 to 0.41, -0.49 to 0.52, -0.50 to 0.41, -0.67 to 0.60, -0.44 to 0.43, respectively, all P > 0.05. In this study, the Bland-Altman plot showed that 95%, 96%, 97%, 97%, 95% plots fell within the 95% LoA in NRS 2002 score, Caprini score, Padua score, wwCHA 2DS 2-VASc score and HAS-BLED score by the two methods, respectively. The all plots of 95% LoA were within the clinically acceptable range (-0.5 to 0.5 scores). The time-consuming of NRS 2002 score, Caprini score, Padua score, CHA 2DS 2-VASc score and HAS-BLED score in IC group were significantly shorter than those in TC group [0.72 (0.71, 0.73) seconds vs. 361.02 (322.41, 361.02) seconds, 0.72 (0.72, 0.73) seconds vs. 196.68 (179.99, 291.20) seconds, 0.72 (0.72, 0.73) seconds vs. 105.75 (92.32, 114.70) seconds, 0.72 (0.71, 0.72) seconds vs. 72.66 (56.24, 84.20) seconds, 0.72 (0.71, 0.72) seconds vs. 51.30 (38.88, 57.15) seconds, respectively, all P < 0.001]. Conclusion:For the above five risk assessments, the TC method and IC method has good consistency in scores, and the IC method is faster, which has good application prospect for clinical application.

Objective:To analyze the relationship between the expression and prognosis of kinesin family member 4A (KIF4A) in renal clear cell carcinoma and explore its potential mechanism.Methods:Information on the KIF4A gene in renal clear cell carcinoma was retrieved from the UALCAN database, including expression levels, survival analysis, and positive and negative correlation gene data, from which the expression levels, prognostic information, and potential mechanisms of KIF4A in renal clear cell carcinoma were derived.Results:KIF4A is highly expressed in renal clear cell carcinoma, and male patients have a higher expression rate than female patients. The higher the tumor grade and the later the N stage, the more expression ( P<0.05). The survival analysis showed that the expression level and prognosis of KIF4A were negatively correlated ( P<0.05). Cyclin B2 (CCNB2), kinesin family member 23 (KIF23), cell division cycle associated 5 (CDCA5), and KIF4A were significantly positively correlated, whereas DHRS12, crumbs protein homolog 3 (CRB3), β-hydroxybutyrate dehydrogenase 2 (BDH2), and KIF4A were significantly negatively correlated. Conclusions:KIF4A plays an important role in the development of renal clear cell carcinoma and can be used as a potential marker and therapeutic target for the diagnosis and prognosis of renal clear cell carcinoma, including in children.

Risk scores assessed by the intelligent calculation method of the ICU patients were collected, including nutritional risk screening 2002 (NRS 2002), Caprini score and Padua score. NRS 2002 score for all patients, Caprini score for surgical patients and Padua score for internal medicine patients were selected. Trends in change of each score were compared between patients admitted to ICU 1, 3, 7 (if necessary), 10 (if necessary), and 14 days (if necessary).Results:A total of 138 patients were involved, including 79 males and 59 females, with an average age of (61.71±18.86) years and an average hospital stay of [6.00 (4.00, 9.25)] days. ① in the group with ICU length of stay ≥ 14 days (21 cases): there was no significant change in the NRS 2002 scores of the patients within 10 days, but the NRS 2002 score was significantly decreased in 14 days as compared with 1 day [3.00 (2.50, 3.50) vs. 4.00 (3.00, 5.00), P < 0.05]; both Caprini and Padua score were increased with prolonged hospital stay and compared with 1 day, the scores at the other time points were significantly increased, especially at 14 days [Caprini score: 5.00 (3.25, 7.00) vs. 2.50 (1.25, 5.50), Padua score: 6.00 (6.00, 7.00) vs. 3.00 (1.00, 3.00), both P < 0.05].② in the group with ICU length of stay from 10-13 days (15 cases): with the prolonged hospital stay, there was no significant change in NRS 2002 score, but both Caprini and Padua score were increased at 3, 7, 10 days, especially at 10 days [Caprini score: 3.00 (2.00, 4.75) vs. 2.00 (0.25, 2.75), Padua score: 5.00 (3.50, 6.00) vs. 2.00 (0.50, 4.00), both P < 0.05].③ in the group with ICU length of stay from 7-9 days (23 cases): compared with 1 day, the NRS 2002 score at 3 days and7 days were decreased, but the Caprini and Padua score were increased, especially at 7 days [NRS 2002 score: 2.00 (1.00, 4.00) vs. 2.00 (2.00, 4.00), Caprini score: 3.00 (2.00, 5.50) vs. 2.00 (0.25, 3.00), Padua score: 5.00 (4.00, 6.00) vs. 2.00 (0, 2.00), all P < 0.05]. ④ in the group with ICU length of stay from 3-6 days (79 cases): compared with 1 day, the NRS 2002 score at 3 days was decreased [NRS 2002 score: 2.00 (1.00, 3.00) vs. 2.00 (1.00, 3.00), P < 0.05], Caprini and Padua score were significantly increased [Caprini score: 3.00 (2.00, 4.00) vs. 2.00 (1.00, 3.00), Padua score: 5.00 (4.00, 5.00) vs. 2.00 (1.00, 3.00), both P < 0.05]. Conclusion:Based on dynamic assessment of intelligent calculation methods, the risk of thrombosis in ICU patients increased with hospital length of stay, and the nutritional risk was generally flat or reducing in different hospitalization periods.

Objective:To evaluate the day-surgery unit-based training of laparoscopic cholecystectomy (LC).Methods:Perioperative data of 438 patients (187 males and 251 females) with a median age of 54 (aged 17 to 91) years undergoing LC during January 2019 to April 2021 in the day-surgery unit of Chinese PLA General Hospital were retrospectively collected and subdivided according to the training methods of surgeons [Group A( n=260): conventional training vs. Group B ( n=178): protocoled stepwise training]. The protocoled stepwise training consists of the rotation in open biliary surgery unit, the stimulator-based laparoscopic training, and the stepwise procedural tutoring. The conventional training features the traditional surgical practice following senior surgeons. The technical data involving operation time, blood loss, the percentages of intraoperative decision-making by senior surgeons and the handing-over of procedure to senior surgeons, etc. were statistically analyzed. Results:The operation time was shortened in Group B [(55±30) min vs. (61±33) min], with significantly decreased percentages of intraoperative decision-making by senior surgeons [7.9% (14/178)vs. 16.9%(44/260), P<0.05] and the handing-over of procedure to senior surgeons [3.4%(6/178) vs. 11.2%(29/260), P<0.05]. Conclusion:Based on the protocoled stepwise training and the consecutive, high-volumed and standardized procedures, the laparoscopic technical proficiency and competency of the trainee surgeons have been improved.
