" Lijie and yellowish sweating" originates from the chapter on stroke and arthralgia diseases in Synopsis of Golden Chamber. Later generations typically interpret it as yellow fluid oozing from painful joints, a characteristic manifestation of arthralgia. In Western medicine, Lijie corresponds to diseases such as gouty arthritis, with its primary clinical manifestations being redness, swelling, heat, and painful joints, most often without yellow fluid discharge. Therefore, the interpretation of " Lijie and yellowish sweating" contradicts the clinical manifestations often observed in this disease. Thus, this article reinterprets the meaning of " Lijie and yellowish sweating" from the pathogenesis of " sweat exposure to water, as if water harms the heart" , combined with the viewpoints of other medical practitioners. Determining the meaning of " yellowish sweating" is crucial for understanding the pathogenesis of arthralgia and clarifying the relationship between arthralgia and yellowish sweating. ZHANG Zhongjing mentioned arthralgia and " yellowish sweating" together, not to differentiate between the two diseases but to emphasize the common pathogenesis of the two, namely, the cold and dampness injuring the heart, blood, and vessels. This paper proposes a new explanation of " Lijie and yellowish sweating" , which suggests that " yellowish sweating" is not confined to the joints but can be found all over the body. The pathogenesis of " Lijie and yellowish sweating" lies in the insufficiency of the liver and kidney and exogenous water dampness, leading to disharmony between nutrient qi and defensive qi and between yin and yang. Primary treatment should harmonize yingfen and weifen, as well as tonify and replenish the liver and kidney. The clinical selection of medicines can be considered Guizhi Decotion, a type of formula. The pathogenesis of " Lijie and yellowish sweating" is complex, and clinical treatment should be comprehensively considered to achieve the best therapeutic effect.

Age-related macular degeneration(ARMD)is a common multifactorial disease among the elderly, which may lead to irreversible vision loss; however, the pathogenesis of ARMD is still unclear. Metabolomics is a relatively new “omics” technique that can provide qualitative and quantitative information about low molecular weight metabolites that make up biological systems, thereby revealing the physiological or pathological state of cell or tissue samples at specific time points. In recent years, increasing evidence suggests that metabolic dysfunction plays an important role in the development and progression of ARMD. Metabolic pathway dysregulation involves lipid metabolism, nucleotide metabolism, amino acid metabolism, and energy metabolism, which may play important roles in the occurrence and development of ARMD. The retina is one of the most metabolically active tissues in the human body, so using metabolomics techniques to measure molecular changes in ARMD will further enhance our understanding of the pathogenesis. This will provide important insights for the prevention and treatment of ARMD, This article reviews the application of metabolomics in ARMD.

Background: s/Aims: Non-invasive models stratifying clinically significant portal hypertension (CSPH) are limited. Herein, we developed a new non-invasive model for predicting CSPH in patients with compensated cirrhosis and investigated whether carvedilol can prevent hepatic decompensation in patients with high-risk CSPH stratified using the new model. Methods: Non-invasive risk factors of CSPH were identified via systematic review and meta-analysis of studies involving patients with hepatic venous pressure gradient (HVPG). A new non-invasive model was validated for various performance aspects in three cohorts, i.e., a multicenter HVPG cohort, a follow-up cohort, and a carvediloltreating cohort. Results: In the meta-analysis with six studies (n=819), liver stiffness measurement and platelet count were identified as independent risk factors for CSPH and were used to develop the new “CSPH risk” model. In the HVPG cohort (n=151), the new model accurately predicted CSPH with cutoff values of 0 and –0.68 for ruling in and out CSPH, respectively. In the follow-up cohort (n=1,102), the cumulative incidences of decompensation events significantly differed using the cutoff values of <–0.68 (low-risk), –0.68 to 0 (medium-risk), and >0 (high-risk). In the carvediloltreated cohort, patients with high-risk CSPH treated with carvedilol (n=81) had lower rates of decompensation events than non-selective beta-blockers untreated patients with high-risk CSPH (n=613 before propensity score matching [PSM], n=162 after PSM). Conclusions Treatment with carvedilol significantly reduces the risk of hepatic decompensation in patients with high-risk CSPH stratified by the new model.

Objective To observe the clinical efficacy of Shen Shuai Ⅱ Granules combined with integrated Western medicine therapy in patients with primary chronic kidney disease(CKD)in stages 3-4 with the syndrome of spleen and kidney qi deficiency,dampness turbidity and blood stasis,and its effects on expression of serum autophagy related proteins.Methods Totally 88 patients were randomly divided into treatment group and control group,with 44 cases in each group.Both groups were given an integrated Western medicine therapy.On this basis,the treatment group was given Shen Shuai Ⅱ Granules,while the control group was given Shen Shuai Ⅱ placebo,1 bag at a time,twice a day,orally.The treatment for both groups lasted for 24 weeks.The clinical efficacy of the two groups was observed.The TCM symptom scores,serum creatinine(Scr),blood urea nitrogen(BUN),uric acid(UA),blood calcium(Ca2+),blood phosphorus(P3-),parathyroid hormone(PTH),and 24-hour urinary protein quantification(24 UPro)before and after treatment were compared in the two groups.The serum levels of autophagy related protein Beclin-1,Atg7,and LC3-Ⅱ were detected by ELISA before and after treatment in the two groups.Safety indexes of both groups were monitored.Results During the treatment,4 cases fell off in the treatment group and 4 cases in the control group.The total effective rate in the treatment group was 55％(22/40),while that in the control group was 30％(12/40).The therapeutic effect in the treatment group was better than that in the control group(P<0.01).Compared with before treatment,the TCM symptom scores in the treatment group decreased after treatment(P<0.01),the levels of Scr,BUN,UA,P3-,PTH,and 24 UPro decreased(P<0.05,P<0.01),while eGFR increased(P<0.01).The levels of Scr in the control group increased(P<0.05),while eGFR decreased(P<0.01).After treatment,the treatment group had lower various TCM symptom scores,Scr,BUN,UA,P3-,PTH,and 24 UPro levels than the control group(P<0.01,P<0.05),and higher eGFR than the control group(P<0.01).Compared with before treatment,the serum levels of Beclin-1,Atg7,and LC3-Ⅱ increased in the treatment group after treatment(P<0.01,P<0.05),while the serum level of Beclin-1 decreased in the control group after treatment(P<0.01).After treatment,the improvement of the above indicators in the treatment group were better than those in the control group(P<0.01,P<0.05).Correlation analysis showed that Beclin-1,Atg7,and LC3-Ⅱ were negatively correlated with Scr and BUN(P<0.05),and positively correlated with eGFR(P<0.05).There was no obvious adverse reaction in both groups.Conclusion The combination of Shen Shuai Ⅱ Granules and integrated Western medicine therapy for the treatment of primary CKD in stages 3-4 with the syndrome of spleen and kidney qi deficiency,dampness turbidity and blood stasis has confirmed efficacy,which can effectively alleviate clinical symptoms,improve renal function,and delay the progression of CKD.The mechanism may be related to improving the level of autophagy in renal.

Objective:To establish a scientific and comprehensive evaluation index system for teaching ability of dental specialist nurses, providing a basis for the selection and assessment of dental nursing instructors.Methods:Based on literature analysis, semi-structured interviews, and group discussions, preliminary evaluation indicators were formulated. From February to April 2023, the Delphi method was used to conduct two rounds of consultation with 27 experts from six provinces and municipalities in China to determine the evaluation index system for the teaching ability of dental specialist nurses. The analytic hierarchy process (AHP) was used to determine the weights of each indicator and its combined weight.Results:The authority coefficient of 27 experts was 0.895. In the two rounds of expert consultation, the effective response rates of the questionnaire were all 100% (27/27), and the Kendall harmony coefficients of various indicators were 0.179 to 0.240 and 0.200 to 0.261 respectively ( P<0.01). The final evaluation index system for teaching ability of dental specialist nurses was formed, including six primary indicators, 15 secondary indicators, and 71 tertiary indicators. Conclusions:The evaluation index system for teaching ability of dental specialist nurses has a reasonable structure, a scientific and rigorous construction process, and can provide a theoretical basis for the allocation of dental specialist human resources and nursing training assessment.

A prokaryotic expression vector for the mutant diphtheria toxin CRM197 was constructed and expressed in Esch-erichia coli cells.Anti-CRM197 antibody concentrations were detected in serum samples of healthy volunteers.The crm 197 gene was codon-optimized in E.coli and cloned into the plasmid pET28a(+)under optimized expression conditions.CRM197 was purified using Ni-NTA spin columns and ion exchange chromatography,and confirmed by western blot analysis.The puri-fied CRM197 was used to detect specific anti-CRM197 antibody levels in serum samples of different age groups.The results showed that soluble codon-optimized CRM197 was successfully expressed under optimized expression conditions.The purity of CRM197 was more than 95％,as determined with Ni-NTA spin columns and ion exchange chromatography,consistent with the single specific bands obtained by western blot analysis and detection of serum levels of the anti-CRM197 antibody.Collec-tively,these results confirmed that the proposed expression strategy achieved high-yield production of soluble CRM197,al-though high levels in human serum may affect evaluation of immune interactions with glycan-CRM197 conjugates for applica-tion as a diagnostic antigen.The diphtheria mutant toxin CRM197 is used in many conjugate vaccines.The synthetic crm 197 gene with codon optimization in pET28a was transformed into E.coli Origami B(DE3)cells.CRM197 was induced by isopro-pyl β-d-1-thiogalactopyranoside and high level accumulation of soluble CRM197 was purified using Ni-NTA spin columns and ion exchange chromatography.The purity of the final prepara-tion reached 95％.CRM197 was used to detect the concentra-tions of the anti-CRM197 antibody in serum samples of healthy volunteers of different ages.The proposed expression strategy yielded high production of CRM197,which could interfere with evaluations of induced immune interactions by glycan-CRM197 conjugates and prohibit application as a diagnostic antigen.

Objective:To explore the application effect of virtual reality (VR) technology in standardized residency training of ureteroscopy in the department of urinary surgery.Methods:Twenty residents without ureteroscopy experience who rotated in Department of Urinary Surgery, The First Affiliated Hospital of Chongqing Medical University from January to November 2023 were randomly divided into two groups, with 10 residents in each group. The traditional teaching group adopted the theory teaching combining skill training. The VR group utilized theory teaching combining VR-assisted skill training, where the process of ureteroscopy was simulated using VR helmet and handles. A skill examination and satisfaction survey were conducted after training to evaluate the teaching effect. SPSS 22.0 was used for the t-test and chi-square test. Results:Compared with the traditional teaching group, the VR group required fewer cases of skilled operation [(3.40±1.00) cases vs. (7.70±1.00) cases] and shorter operation time [(2.70±0.67) min vs. (3.90±1.37) min] ( P<0.05). The VR group was significantly better than the traditional teaching group in the following dimensions: fluency of scope insertion [(2.30±0.82) points vs. (1.40±0.70) points], degree of mucosal injury [(2.20±0.92) points vs. (1.40±0.70) points], and operational proficiency under the ureteroscope [(2.40±0.70) points vs. (1.60±0.84) points] ( P<0.05); there were no significant differences between the two groups in proficiency level and visual field stability scores ( P>0.05). The VR group had higher satisfaction scores in training method (80% vs. 30%) and more confidence to carry out ureteroscopy independently (70% vs. 20%). Conclusions:Through simulated training with VR technology, resident trainees can significantly shorten the learning curve of ureteroscopy and improve teaching satisfaction.
