OBJECTIVE To identify the chemical constituents of Rhamni Songoricae Fructus and to establish their fingerprints and the method for simultaneous determination of four constituents to comprehensively evaluate the quality of Rhamni Songoricae Fructus. METHODS The chemical constituents in Rhamni Songoricae Fructus were qualitatively analyzed by ultra-performance liquid chromatography quadrupole-time-of-flight tandem mass spectrometry. The fingerprints of 15 batches of Rhamni Songoricae Fructus were established by HPLC and chemometric analysis was performed by using SPSS 26.0 and SIMCA 14.1 software； the contents of quercetin， kaempferol， kaempferide and emodin were determined by the same method. RESULTS A total of 35 constituents were identified， including 28 kinds of flavonoids， 5 kinds of anthraquinones and 2 kinds of organic acids. A total of 19 common peaks were identified in the HPLC fingerprints， recognizing quercetin， kaempferol， kaempferide and emodin. The similarities between HPLC fingerprints of 15 batches of samples and control chromatograms were greater than 0.9. The results of cluster analysis showed that 15 batches of samples were divided into 2 classes， of which S1-S5， S7 and S9 were one class and the rest were one class， similar to the results of principal component analysis. The results of the orthogonal partial least squares- discriminant analysis showed that the variable importance projections of peaks No. 2， 6， 1， 11 （quercetin）， 3， 14， 8， 10， 19 （emodin）， 5 were all greater than 1. The contents of quercetin， kaempferol， kaempferide and emodin ranged from 0.710 to 10.478 mg/g， 0.236 to 0.660 mg/g， 0.334 to 3.039 mg/g， and 0.261 to 0.504 mg/g. CONCLUSIONS The constructed chemical constituent identification， fingerprint and content determination methods are simple， feasible and reproducible， which combined with chemometric analysis can be used for comprehensive evaluation of the quality of Rhamni Songoricae Fructus.

Objective To conduct a visual analysis of the current status, hotspots, and frontiers of research on renal cell carcinoma targeted therapy using VOSviewer software. Methods Literature related to renal cell carcinoma targeted therapy published between January 1, 2006 and December 31, 2023, from the Web of Science (WOS) Core Collection database were retrieved. Eligible articles were screened and subjected to bibliometric and visual analysis using VOSviewer software. Results A total of 1, 009 articles were selected, with an overall increasing trend in annual publication volume. The top three countries in terms of publication output were the United States, China, and Italy, while the top three institutions were Harvard University, The University of Texas, and France Uni-cancer Institute. The analysis of the core author collaboration network revealed close collaboration among researchers in the United States and the United Kingdom, whereas collaboration between China and foreign countries was limited, resulting in a relatively loose collaboration network. Through co-occurrence clustering analysis of high-frequency author keywords, nine clusters were generated, with hotspots focusing on targeted and immune combination therapy, efficacy, prognosis, drug resistance, targets, and biomarkers. Conclusion Remarkable progress has been made in renal cell carcinoma targeted therapy research over the past decade; however, drug resistance and adverse reactions to targeted therapies remain challenges in clinical treatment. Research related to targeted drug resistance mechanisms, novel targeted drugs, and effective predictive biomarkers has significantly increased. Grasping the developmental trends in this fieldis crucial, and VOSviewer's visual analysis can offer an intuitive representation of the current status, hotspots, and frontiers, thereby providing researchers with a valuable reference.

Objective:To explore the impact of King's theory of goal attainment combined with goal setting on the effect of standardized training of general practitioners.Methods:A total of 39 general practitioners who underwent the standardized training in The Fifth Affiliated Hospital of Xinjiang Medical University from January 2019 to January 2020 were classified as control group, and traditional teaching was adopted. Another 42 general practitioners who underwent the training in The Sixth Affiliated Hospital of Xinjiang Medical University during the same period were classified as a research group, and the teaching based on King's theory of goal attainment combined with goal setting was adopted. The theoretical knowledge and operational skills scores, changes in clinical comprehensive ability before and after the training, and teaching recognition were compared between the two groups. SPSS 25.0 was used for t test and chi-square test. Results:After the training, the scores of theoretical knowledge and operation skills of the research group were both higher than those of the control group [(92.83±5.62) vs. (85.47±12.11); (90.15±7.22) vs.(83.36±11.24)]. There was no significant difference between the two groups in the scores of inquiry and communication ability, problem-solving ability, general medical thinking ability, interpretation ability of auxiliary examination results, clinical analysis and decision-making ability, team cooperation ability, community common disease diagnosis and treatment ability and humanistic care ability before the training ( P>0.05); the above scores were all improved after the training ( P<0.05), and the above scores of the research group were significantly higher than those of the control group ( P<0.05). The total recognition of teaching in the research group was 95.24%(40/42), which was significantly higher than that 76.92%(30/39) in the control group ( P<0.05). Conclusion:The application of King's theory of goal attainment combined with goal setting in standardized training of general practitioners can effectively improve the level of general practitioners' theoretical knowledge, operational skills, clinical comprehensive ability and recognition of teaching.

Objective: To explore the mediating effects of self-focused attention between social anxiety and interpersonal needs. Methods: Totally 467 college students [159 males and 221 females, mean age (21 ±2)] were assessed with the Social Anxiety Scale (SAS), Self-Focused Attention Scale (SFAS) and Interpersonal Needs Questionnaire (INQ ). The bootstrap method was used to test the mediating effect Results: The SFAS and INQ scores were higher in female students than in males (Ps <0.01). The scores of SAS, SFAS, and INQ were positively correlated each other (r = 0.20 - 0.90, Ps < 0.01). Self-focused attention has a full mediating effect between social anxiety and interpersonal needs, and the 95％ confidence interval was (0.34, 0.59). Conclusion: It suggests that the effect of interpersonal needs on social anxiety may be achieved through self-focused attention in college students. Reducing the level of self-focused attention may be an important way to alleviate social anxiety among college students.

Objective To observe the effect of electroacupuncture on early enteral nutrition (EEN) support in patients with severe craniocerebral injury.Methods A prospective, randomized, controlled study was conducted, 50 patients with severe craniocerebral injury admitted to the the Department of Intensive Care Unit of Traditional Chinese Medicine Hospital of Ningbo from January 2014 to October 2016 were enrolled, and they were randomly divided into electroacupuncture experimental group (26 cases) and conventional treatment control group (24 cases) by randome number table. Enteral nutrition (EN) support was implemented in 24 - 48 hours after admission for all the patients, additionally, the electroacupuncture experimental group was treated by electroacupuncture stimulating acupoint from the 1st day after admission, once 30 minutes daily for consecutive 10 days. The levels of EN calorie reaching standard situation and the parenteral nutrition (PN) necessary for addition were recorded on 3 days and 5 days after admission; the nasal feeding amount of the two groups was recorded on the 1, 4, 7 days; the incidences of complications during EN support period were observed in both groups.Results The proportion of EN calorie reaching the standard in electroacupuncture experimental group was significantly higher than that in the conventional treatment control group in 5 days of treatment [92.3% (24/26) vs. 70.8% (17/24),P < 0.05]. The proportions necessary for addition of PN support were lower in electroacupuncture experimental group than those in the conventional treatment control group on 3 days and 5 days of treatment [3 days: 19.2% (5/26) vs. 25.0% (6/24), 5 days: 7.7% (2/26) vs. 16.7% (4/24)], but there were no significant statistical differences between the two groups (bothP > 0.05). The nasal feeding amounts in electroacupuncture experimental group were significantly higher than those in the conventional treatment control group on 4 days and 7 days of treatment [4 days (mL): 1292.31±123.04 vs.1204.17±139.81,7 days (mL):1342.31±113.75 vs.1275.00±103.21, bothP < 0.05]. The incidence of complications of the electroacupuncture experimental group was significantly lower than that of the conventional treatment control group in 10 days of treatment [26.92% (7/26) vs. 41.67% (10/24),P < 0.05].Conclusions Application of electroacupuncture has a certain clinical value during implementing EN support for treatment of patients with severe craniocerebral injury, early intervention of electroacupuncture can effectively improve the patients' gastrointestinal function and elevate the successful rate of EN, and the therapy is simple, effective and safe without any obvious adverse reactions.

Objective To observe the clinical efficacy of warm needling in treating chronic prostatitis due to kidney-yang deficiency.Method Seventy-eight patients with chronic prostatitis due to kidney-yang deficiency were randomized into a treatment group of 40 cases and a control group of 38 cases. The treatment group was intervened by warm needling, while the control group was by oral administration of Terazosin hydrochloride tablets. The National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) and white blood cell (WBC) count in prostatic fluid were observed before and after treatment, and the clinical efficacies were compared.Result The total effective rate was 92.5% in the treatment group versus 76.3% in the control group, and the difference was statistically significant (P<0.05). The NIH-CPSI scores and WBC counts were significantly changed in both groups after treatment (P<0.05). After treatment, the NIH-CPSI score of the treatment group was significantly different from that of the control group (P<0.05). There was no significant difference in comparing the WBC count between the two groups after treatment (P>0.05).Conclusion Warm needling is an effective approach in treating chronic prostatitis due to kidney-yang deficiency.

Objective To investigate the relationship between baseline serum uric acid and the severity of coronary artery disease ( CAD ) in the first-degree relatives or non-first-degree relatives of men with type 2 diabetes. Methods Three hundred and eighty-one men with negative coronary angiography for the first time were divided into diabetes and non-diabetes groups and followed-up for 5 years. The primary outcome was acute coronary syndrome suspected during subsequent 5 years, and the coronary angiography was conducted simultaneously. The severity of CAD was assessed by the coronary stenosis index ( CSI) and the number of coronary lesion vessels. Results In normal blood glucose group, serum uric acid was higher in the first-degree relatives of diabetics compared with non-first-degree relatives(P<0. 01), along with higher morbidity of CAD, CSI, and coronary lesion vessels (all P<0.01). Correlation analysis showed that CSI(r=0. 250, P=0. 041) and coronary lesion vessels(r=0. 252, P=0. 040) in non-diabetics group were associated with baseline levels of serum uric acid. Conclusion The elevation of serum uric acid was closely related to subsequent CAD, especially in first-degree relatives of male with type 2 diabetes, which could be used as an early indicator for CAD prediction.
