ObjectiveTo analyze the quantity-quality transfer of standard decoction of Ginseng Radix et Rhizoma（GRR） decoction pieces produced by fresh and traditional cutting， and to provide reference for quality control and application development of the decoction pieces produced by fresh cutting. MethodTen batches of representative GRR decoction pieces produced by fresh and traditional cutting and their standard decoctions were prepared by standard process， and high performance liquid chromatography（HPLC） fingerprint of the standard decoction was established and performed on an Agilent EC-C₁₈ column（4.6 mm×150 mm， 2.7 μm） with acetonitrile（A）-0.1% phosphoric acid aqueous solution（B） as the mobile phase for gradient elution（0-23 min， 18%-21%A； 23-35 min， 21%-28%A； 35-80 min， 28%-32%A）， and the detection wavelength was 203 nm. Then similarity evaluation， principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA） of fingerprint of the standard decoction were performed to screen the differential components with variable importance in the projection（VIP） value>1. Quantitative analysis was carried out on the screened known differential components， and combined with the indicators of the dry extract rate and the transfer rate， to explore the differences in the quantity-quality transfer between the standard decoction of GRR decoction pieces produced by fresh and traditional cutting. ResultThe fingerprint similarity of the standard decoction of GRR decoction pieces produced by fresh and traditional cutting was more than 0.950， and 18 common peaks were identified， including 9 identified common peaks. The results of PCA and PLS-DA showed that there were some differences in the contents of index components between the two standard decoctions. The contents of ginsenoside Rg₁， Re and Ro in GRR decoction pieces produced by fresh cutting were higher than those in traditional decoction pieces， while the contents of ginsenoside Rb₁， Rc ， Rb₂ and Rd were lower than those in traditional decoction pieces. The contents of ginsenoside Rg₁， Re， Rb₁ and Ro in the standard decoction of GRR decoction pieces produced by fresh cutting were higher than those in the standard decoction of traditional decoction pieces， while the contents of ginsenoside Rc ， Rb₂ and Rd were comparable between the two standard decoctions. Compared with the standard decoction of the traditional decoction pieces， the average transfer rates of ginsenoside Rg₁， Rb₁， Rc， Rb₂ and dry extract rate of the standard decoction of GRR decoction pieces produced by fresh cutting were significantly increased（P<0.05）， and the average transfer rate of ginsenoside Re and Rd also increased， but the difference was not statistically significant. ConclusionThe dry extract rate， content and transfer rate of index components of standard decoction of GRR decoction pieces produced by fresh cutting are better than those of the standard decoction of traditional decoction pieces， which can provides data support for the subsequent clinical application of fresh cutting products.

Objective:To analyze the current research status and hot spots of metabolic syndrome after renal transplantation, and provide reference for domestic research in this field.Methods:Computer retrieval of the literature related to renal transplantation metabolic syndrome in the Chinese Biomedical Literature Service System and the Web of Science core collection database was conducted from January First, 2002 to December 31, 2022. The retrieval results were analyzed using Citespace.6.1.R3c software.Results:After screening, a total of 1024 papers related to metabolic syndrome of renal transplantation were included, including 409 Chinese papers and 615 English papers. In the past 20 years, the number of papers related to metabolic syndrome of renal transplantation in foreign countries has increased progressively, and the overall domestic literature has not increased significantly. Domestic and international research focuses mainly on the epidemiology, pathogenesis, risk factors and related hazards of metabolic syndrome in renal transplantation.Conclusions:The research on metabolic syndrome in renal transplantation has received more and more attention, and still has great research prospects. The risk factors and intervention methods of metabolic syndrome in renal transplantation have been the research focus of scholars at home and abroad in recent years. Chinese scholars can further explore on the basis of previous research, strengthen the exchange and cooperation between different fields, institutions and countries, so as to optimize and improve the related research of metabolic syndrome in kidney transplantation.

Objective:To observe the clinical and imaging features of patients with retinal vein occlusion (RVO) complicated with retinal artery occlusion (RAO).Methods:A retrospective clinical study. Fifteen patients with 15 eyes with RVO combined with RAO and macular edema diagnosed by ophthalmology examination in the Department of Ophthalmology, First People's Hospital of Xianyang City during 2 years from February 1, 2022 to January 31, 2024 were included in the study. Branch retinal vein occlusion (BRVO) combined with branch retinal artery occlusion (BRAO) occurred in 3 cases and 3 eyes. Central retinal vein occlusion (CRVO) complicated with central retinal artery occlusion (CRAO) in 12 eyes. Best corrected visual acuity (BCVA), intraocular pressure, scanning laser ophthalmoscope, optical coherence tomography (OCT), fluorescein fundus angiography (FFA) and serum homocysteine were all performed. OCT angiography (OCTA) was performed in 6 eyes. All eyes were treated with intravitreal injection of anti-vascular endothelial growth factor drugs. After the initial 1 treatment, dosage was assessed as needed. Follow-up was performed every month for 12 months after treatment. FFA inspection was performed at 3 months. During follow-up, it was found that there were no perfusion areas of capillaries, and retinal laser photocoagulation therapy was given in time. Fundus manifestations, FFA, OCT, OCTA characteristics and causes of disease were analyzed retrospectively.Results:There were 15 eyes in 15 cases, 9 eyes in 9 males; 6 women with 6 eyes. Age was (61.0±9.7) years. All complained of painless vision loss in one eye. All eyes were positive for relative afferent pupillary disorder. Contralateral congenital optic disc defect was in 1 case; hypertension was in 6 cases; hyperhomocysteinemia was in 2 cases; cerebral infarction was in 3 cases; coronary heart disease was in 1 case. CRVO combined with CRAO was in 12 eyes BCVA light sensitivity-0.25. The BCVA of BRVO combined with BRAO were 0.1, 0.4 and 0.25, respectively. All the patients had retinal edema in the posterior pole of the eye, venous sinuous, dilated, thin arteries and stiff shape. The retina presents with flaky or flame-like bleeding. Posterior polar retinal lint patch was in 13 eyes. In 12 eyes with CRVO combined with CRAO, optic disc edema was observed and the boundary was not clear. In 3 eyes with BRVO combined with BRAO, no obvious abnormality was found in the optic disc, and the boundary was clear. FFA examination showed no or prolonged arterial filling, delayed retinal vein laminar flow, relatively slow or even no capillary filling, macular arteriole atretosis to varying degrees, arch ring structure destruction, optic disc telangiectasia and fluorescein leakage. OCT examination showed that the middle and inner layers of the retina were thickened to varying degrees, the diffuse reflex was enhanced, the interlayer structure was unclear, and the reflex of the lower retinal tissue was weakened. The blood flow density of superficial capillary plexus and deep capillary plexus (DCP) decreased in 6 eyes undergoing OCTA examination. Decreased or interrupted blood flow in the vascular bed of DCP. During the follow-up period, there were 13 eyes with no perfusion area of retinal capillary. The time of occurrence was (1.14±0.95) (0-2) months, and the area was 10-75 disc area. Optic nerve atrophy occurred in 5 eyes. At the last follow-up, visual acuity increased, unchanged and decreased in 12, 2 and 1 eyes, respectively.Conclusions:The pathogenesis of RVO-RAO is complicated. Most RVO and RAO occurred simultaneously, and a few RVO occurred several days after RAO. Although the RAO manifestations are not typical, the radiographic features are both RVO and RAO. Compared with BVRO combined with BRAO, the prognosis of visual acuity in CRAO patients with CRVO is worse.

Objective:This work aims to assess the distribution of peripheral blood monocyte subsets, the expression level of the functional markers in rheumatoid arthritis (RA) patients, and analyze the correlation between the above indexes and the onset of RA.Methods:Peripheral blood mononuclear cells were collected and isolated from 62 RA patients, 52 healthy control (HC) and 12 disease control group′s patients via density centrifugation. The enrolled patients were attended or underwent physical examination in East Hospital, Tongji University from June 2020 to December 2021. Monocytes could be classified into classical (CM), intermediate (IM) and non-classical (NCM). Then, the flow cytometry was performed to examine the distribution of monocyte subsets and the measure the expression level of human leukocyte antigen DR (HLA-DR), intracellular tumor necrosis factor α (TNF-α) in peripheral blood monocytes. The statistical methods in this study mainly include: Kruskal-Wallis H test, Chi-Square test, Mann-Whitney U test, Wilcoxon matched-pairs signed ranks test, Spearman correlation coefficient test and Logistic regression analysis. The diagnostic value of IM proportion in RA was analyzed by ROC curve. Results:The monocytes number and monocytes proportion in white blood cells were much higher in RA [0.40 (0.40, 0.50), 7.60% (5.97%, 8.53%)] and disease control [0.40 (0.40, 0.68), 8.20% (5.85%, 10.28%)] compared with HC [0.30 (0.30, 0.40), 5.80% (5.03%, 6.38%)] ( H=24.733, P<0.001; H=27.469, P<0.001). A statistic-significant difference was detected among the proportion of CM[85.49%(76.91%,89.21%),88.94%(86.36%,91.72%),90.26%(80.25%, 92.56%)],IM[11.65%(8.47%,17.89%),7.89%(5.36%,10.75%), 5.56%(4.17%, 8.27%)], NCM[2.22%(1.39%, 3.74%), 2.49%(1.74%, 4.66%), 5.13%(3.39%, 9.85%)] in RA group, HC group and disease control group ( H=11.389, P=0.003; H=20.815, P<0.001; H=10.640, P=0.005). The proportion of CM was lower in RA and the IM proportion was increased in RA( P=0.003; P=0.003). The intracellular TNF-α level of monocytes in all three groups revealed the trend that IM>NCM>CM. The intracellular TNF-α in IM of RA was positively associated with serum TNF-α ( r=0.376, P=0.041). The HLA-DR expression in IM subsets were higher than CM and NCM subsets in all RA,HC and disease control groups. The expression of HLA-DR of IM in RA group and disease control was higher than HC group [8 611.50 (6201.3, 9890.8), 10 295.0 (7 899.0, 13632.0), 6 278.00(4 057.8, 9522.0), H=10.495, P=0.005]. There were no correlations between the proportion of peripheral blood IM and clinical characteristics CRP ( r=0.119, P=0.359), RF ( r=0.204, P=0.112) and ESR ( r=0.153, P=0.236). Logistic regression analysis showed that the proportion of IM ( OR=1.169, 95% CI 1.003-1.363, P=0.046), CRP ( OR=1.277, 95% CI 1.000-1.631, P=0.050), RF ( OR=1.179, 95% CI 1.080-1.287, P<0.001) are positively correlated with RA onset. The area under ROC curve for diagnosis of RA with IM proportion was 0.687, and the 95% confidence interval was 0.590-0.784, P<0.001. Conclusions:The distribution of monocyte subsets in peripheral blood of RA patients is abnormal. The increase in the proportion of IM, the enhanced antigen-presenting ability, and the increased level of TNF-α secretion in RA patients may play an important role in the pathogenesis of RA.

Objective:To explore the application effect of perioperative peripheral venous pathway chain management scheme in surgical patients.Methods:This study was a historical control study. Using the convenient sampling method, surgical patients who were admitted to Peking University People's Hospital from March to July 2018 were selected as the control group and they were given routine intravenous care. The surgical patients who were admitted from January to June 2019 were selected as the observation group, and they were given perioperative peripheral venous pathway chain management scheme on the basis of the control group. A total of 528 patients were included, including 5 cases of detachment due to patient change of treatment plan, 5 cases of detachment due to temporary cancellation of operation, and 3 cases of detachment without relevant data collected by puncture inspection during hospitalization. Finally, 515 patients were included, including 247 cases in the control group and 268 cases in the observation group. A total of 589 indwelling needles were indwelled in the observation group and 474 indwelling needles in the control group. The indwelling needle site, indwelling needle model, re-catheterization rate, indwelling time, failure rate of indwelling needles, venipuncture consumables costs and nursing costs were compared between the two groups.Results:The number of indwelling needles in the medial forearm vein and lateral forearm vein in the observation group was more than that in the control group, and the differences were statistically significant ( P<0.01) . The number of indwelling 20 G indwelling needles in the observation group was more than that in the control group, and the number of indwelling 18 G indwelling needles in the observation group was less than that in the control group, and the differences were statistically significant ( P<0.01) . The failure rate of indwelling needle, re-catheterization rate, venipuncture consumables costs and nursing costs in the observation group were lower than those in the control group, and the differences were statistically significant ( P<0.01) . Conclusions:The perioperative peripheral venous access chain management scheme can effectively reduce the failure rate andre-catheterization rate of indwelling needles in surgical patients, reduce related costs, and improve the quality of peripheral venous care.

Objective:To explore the research hotspots and frontiers of kidney transplantation nursing at China and abroad from 2010 to 2020.Methods:The CiteSpace software was used to search and analyze the related articles on kidney transplantation nursing included in major domestic and foreign databases from January 1, 2010 to December 31, 2020. There were 538 articles in total, including 267 articles in China National Knowledge Infrastructure (CNKI) and 271 articles in the Web of Science. Based on the annual publication volume, high-frequency keywords and keyword co-occurrence, we drew keyword clusters, keyword timelines and keyword emergence maps, and analyzed research hotspots and frontiers in this field.Results:In the past 10 years, the research hotspots of kidney transplantation nursing at China and abroad mainly focused on the complications of kidney transplantation during the perioperative period, psychological nursing, drug treatment compliance, health education, and quality of life. The research frontiers mainly included perioperative complications of kidney transplantation, new postoperative diseases, drug treatment compliance, and nursing model construction.Conclusions:There are certain differences between domestic and foreign research on kidney transplantation nursing. Research on the research hotspots and frontiers in the field of kidney transplantation nursing will help to further explore on the basis of existing research, and ultimately improve the success rate of kidney transplantation and the long-term outcome of patients.

Objective:To investigate the job stress of specialist nurses in the Operating Room, and analyze the correlation among job stress, job burnout and organizational commitment based on the job demand-control model.Methods:This study was a cross-sectional study, using random cluster sampling to select 377 specialist nurses in the Operating Room in Beijing from March to June 2017. The Job Content Questionnaire, Maslach Burnout Inventory-Human Service Survey-Chinese Version and Organizational Commitment Scale were used to investigate the job stress, job burnout and organizational commitment of specialist nurses in the Operating Room. AMOS 22.0 software was used to verify the relationship between the three.Results:Finally, data of 243 specialist nurses in the Operating Room from 30 ClassⅢ hospitals in Beijing was collected. The job demand score was (37.47±4.16) , and the lowest was 28, and the highest was 48; the job control score was (61.25±8.49) , and the lowest was 30, and the highest was 84; the job stress score was (34.21±11.05) , and the lowest was 12.96, and the highest was 81.33; the comprehensive score of job burnout was (3.36±1.26) , and the lowest was 0.9, and the highest was 6.0; the organizational commitment score was (3.66±0.91) , and the lowest was 1.33, and the highest was 5.00. Correlation analysis showed that the job stress of specialist nurses in Operating Room was positively correlated with emotional exhaustion and depersonalization ( r=0.475, 0.392; P<0.01) , and negatively correlated with organizational commitment ( r=-0.423, P<0.01) ; the organizational commitment of the specialist nurses in Operating Room was negatively correlated with emotional exhaustion and depersonalization ( r=-0.418, -0.519; P<0.01) . The results of mediating effect analysis showed that job stress could directly affect organizational commitment ( r=-0.222) , and could indirectly affect organizational commitment through job burnout ( r=-0.201) , and the indirect effect accounted for 47.5% of the total effect. The hypothetical model matched the data well, and the model could explain 34.9% of the organizational commitment variation. Conclusions:Specialist nurses in the Operating Room have high levels of job stress and job burnout. The lower the level of organizational commitment, the higher the job stress, and the higher the level of job burnout, and the lower the level of organizational commitment. It is reminded that nursing managers should set up specialist nurse positions, clarify responsibilities, rights, and benefits, and give sufficient authorization and time to relieve the job stress of specialist nurses in the Operating Room, and to reduce job burnout and improve organizational commitment.

Objective:To investigate the role and influencing factors of case design in PBL teaching.Methods:Thirty-two six-year-program undergraduates from the Department of Medicine of Peking University in batch 2014 and batch 2015 were selected as the subjects. PBL teaching was used in the practice class of experimental diagnostics. The feedback effects of four times PBL courses were analyzed by collecting questionnaires for teachers, students, and supervisors. The data obtained from the five-point questionnaire and the question-and-answer questionnaire were analyzed by one-way ANOVA and statistics respectively. Then the problems in case preparation process are discussed and the experience of case design is summarized. SPSS 13.0 was used in this study.Results:The 5-point questionnaire showed that the average score of anemia PBL course was the highest among students' self-evaluation and mutual evaluation of teachers and students (4.84 points, 4.79 points), with statistical significance compared with other courses ( P<0.05). The question-and-answer questionnaire survey showed that 93.75% of the students generally agreed with the teaching model of anemia cases; 78.13% and 59.38% of the students believed that it was difficult to set up cases of infection and coagulation, which affected the classroom effect; and 50% of the supervisors thinked that the students' level should be taken into account in case design and oral expression should be avoided. Conclusion:Case design is the key to PBL teaching. Summarizing the experience of case design can lay a good foundation for the establishment of PBL teaching database.

Objective: To evaluate the sensitivity and specificity of immunohistochemistry (IHC) in the classification of cardiac amyloidosis on endomyocardial biopsy (EMB) and heart allograft. Methods: Twenty cardiac tissues from 19 patients at Fuwai Hospital from January, 1990 to April, 2017 with histopathologic features of amyloidosis and Congo red staining positivity were included. IHC was performed with monoclonal antibodies against AA amyloid and polyclonal antibodies against transthyretin (ATTR), λ-light chain (AL-λ), κ-light chain (AL-κ), ApoAⅠ, ApoAⅡ, ApoA Ⅳ and β₂-microglobin. The extent of interstitial staining was evaluated by light microscopy, and three patterns were recognized; these included diffuse pericellular pattern, discrete pericellular pattern, and nodular pattern. Two patterns of vascular deposition were also noted, including arterial pattern and venous pattern. Endocardial involvement was also assessed and recorded. Results: Nineteen cases were divided into three groups according to the pattern of proteins expression in specimens. The first group (5 cases) only showed single protein expression on EMB. The second group (6 cases) showed more than one protein expression, but one of them was intensely stained or any staining of any protein together with ApoA Ⅳ co-staining. The third group (8 cases) also showed more than one protein expression and all of them had intense staining. Amyloid deposits were successfully subtyped as AL-λ, ATTR, AL-κ and ApoAⅠby IHC in the former two groups with the sensitivity of 11/19. In the third group, amyloid deposits could not be subtyped by immunohistochemistry due to their poor specificity. The pericellular pattern tended to favor AL over ATTR amyloidosis and vascular deposition tended to favor ATTR. Conclusions Amyloid deposits can be reliably subtyped in diagnostic cardiac specimens using IHC. The co-deposition of chaperon proteins, the distribution of amyloid proteins and clinical features are also auxiliary to subtype cardiac amyloidosis.
