Based on the interaction between supramolecule of traditional Chinese medicine and enterobacteria, the material basis of Rhei Radix et Rhizoma and Coptidis Rhizoma was explored. Scanning electron microscopy (SEM) and dynamic light scattering (DLS) were used to characterize the morphological differences of Rhubarb single decoction, Coptis single decoction and Rhubarb and Coptis co-decoction. An in vitro antibacterial model (E. coli, E. faecium and B. subtilis) was established to evaluate the damage effect of the combination of Rhei Radix et Rhizoma and Coptidis Rhizoma on enterobacteria. Ultra high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was used to analyze the changes of chemical components of single decoctions and co-decoctions. The co-decoction of Rhei Radix et Rhizoma and Coptidis Rhizoma was turbid after decocting. The spherical particles of 300-400 nm were observed under SEM, and the co-decoction was more uniform and stable than that of single decoction. The interaction between supramolecules formed after the combination of Rhei Radix et Rhizoma and Coptidis Rhizoma and enterobacteria was significantly different from that of single decoction. In the process of interaction between supramolecules and enterobacteria, the spherical state was maintained, and the medicinal ingredients in Coptidis Rhizoma or Rhei Radix et Rhizoma were blocked, which could effectively alleviate the damage to enterobacteria. This study provided a reference for subsequent studies on the regulation of intestinal flora homeostasis by the combination of Rhei Radix et Rhizoma and Coptidis Rhizoma.

Tuberous sclerosis complex(TSC)is a rare genetic disease that can lead to benign dysplasia in multiple organs such as the skin, brain, eyes, oral cavity, heart, lungs, kidneys, liver, and bones. Its main symptoms include epilepsy, intellectual disabilities, skin depigmentation, and facial angiofibromas, whilst incidence is approximately 1 in 10 000 to 1 in 6000 newborns. This case presents a middle-aged woman who initially manifested with epilepsy and nodular depigmentation. Later, she developed a lower abdominal mass, elevated creatinine, and severe anemia. Based on clinical features and whole exome sequencing, the primary diagnosis was confirmed as TSC. Laboratory and imaging examinations revealed that the lower abdominal mass originated from the uterus. CT-guided biopsy pathology and surgical pathology suggested a combination of leiomyoma and abscess. With the involvement of multiple organs and various complications beyond the main diagnosis, the diagnostic and therapeutic process for this patient highlights the importance of rigorous clinical thinking and multidisciplinary collaboration in the diagnosis and treatment of rare and challenging diseases.

The effect of different concentrations of glycyrrhizic acid (GA) and Zn²⁺ on the self-assembly of metal complexes was investigated by forming metal complexes, and the properties and assembly mechanisms of the formed carrier-free supramolecular hydrogel were characterised. Scanning electron microscopy (SEM) and zeta potential were used to characterise the microscopic morphology and stability of the GA-Zn complex hydrogel, which had spherical-like particles of about 1 μm with good stability; the rheometer was used to detect its materialistic properties, which showed excellent stability, self-healing property and reversibility; through in vitro bacterial inhibition, it was found that the GA-Zn carrier-free supramolecular hydrogel has enhanced bacterial inhibition function after assembly. The hydrogel was also found to possess both anti-inflammatory and antioxidant efficacy when evaluated using LPS and H₂O₂ induced RAW 264.7 cell damage models, respectively. The above results suggest that GA-Zn hydrogel not only has good materialistic properties, but also possesses good antibacterial, anti-inflammatory and antioxidant activities, which has the value of clinical research as a carrier-free multi-functional antimicrobial dressing, and the present study provides a reference for the discovery of novel biomedical materials from active molecules of natural traditional Chinese medicine.

Tinnitus is a clinically refractory disease with a high incidence.LAI's Tongyuan acupuncture method believes that tinnitus is nothing more than the two ends of deficiency and excess.The deficiency is closely related to original spirit,and the excess is related to the pathological factors such as externally-contracted six pathogenic factors,phlegm-damp and blood stasis,and qi stagnation and yang constraint.The Tongyuan acupuncture method is based on original spirit,takes the two vessels of conception vessel(CV)and governor vessel(GV)as the general outline,takes the regulation of yin and yang as the main method,pays attention to the combination of local and overall,and emphasizes the application of tonification and purgation,and has the clinical effect of reinforcing healthy qi and dispelling pathogen,cultivating the vital essence.In clinical application,the method of'unblocking governor vessel and nourishing spirit'is used to play the role of heart and brain nourishing spirit and warming and supporting yang qi.The method of'conducting qi back to its source'has the effect of cultivating the vital essence and regulating qi movement.The treatments should be cooperated according to the syndromes,so that the pathogens can be expelled and healthy qi can be settled.Qi and blood have origins of generation and transformation and normally nourishing in the ear,so as to effectively alleviate the patient's tinnitus symptoms.This paper summarizes and analyzes Professor LAI Xin-Sheng's Experience in the diagnosis and treatment of tinnitus by Tongyuan acupuncture method,and provides a new acupuncture treatment plan for clinical application.

Objective:To analyze the efficacy and safety of flumatinib,a second-generation tyrosine kinase inhibitor(TKI)independently developed in China,in patients with chronic myelogenous leukemia in chronic phase(CML-CP)who falied first-line and second-line treatment.Methods:The clinical data of 30 CML-CP patients treated with flumatinib in Lianyungang First People's Hospital from January 2020 to September 2022 were collected retrospectively.Among them,15 patients who received imatinib first-line treatment but failed treatment were included in the second-line group,and the other 15 patients who failed second-line treatment with nilotinib or dasatinib were included in the third-line group.The hematological and molecular responses of the patients in the two groups at 3,6 and 12 months of treatment,and the event-free survival(EFS)and adverse reactions of patients at the end of follow-up were statistical analyzed.Results:At 3,6,and 12 months of treatment,10,11,and 12 patients in the second line group achieved major molecular response(MMR),which was higher than that of 3,4,and 5 patients in the third line group(P=0.010,P=0.011,P=0.010).At 3 months of treatment,12 and 13 patients achieved complete hematological response(CHR)and early molecular response(EMR)in the second-line group,which was higher than that of 9 and 13 patients in the third-line group,but the difference between the two groups was not statistically significant(P=0.232,P=1.000);At 6 and 12 months of treatment,6 and 7 patients in the second-line group achieved MR4.5,which were higher than of 3 and 2 cases in the third-line group,but the difference was not statistically significant(P=0.427,P=0.713).The hematological adverse reactions of patients in the second-line group during treatment the period were mainly grade 1-2 thrombocytopenia and anemia,and no grade 3-4 of adverse reactions occurred.In the third-line group,there were 2 cases of grade 1-2 thrombocytopenia,grade 1-2 anemia and white blood cell 3 cases were reduced each,1 case of grade 3-4 anemia,2 cases of grade 3-4 neutropenia.The non-hematological adverse reactions in the second-line group were rash(2 cases),headache(1 case),diarrhea(1 case),fatigue(1 case),limb pain(1 case).There were 1 cases of diarrhea,1 cases of nausea,and 1 cases of edema in the third-line group.There was no statistical significance in hematological and non-hematological adverse reactions between the two groups of patients(P＞0.05).At the end of follow-up,the EFS rate of patients in the second-line group was higher than that in the third-line group(100％vs 93.3％),but the difference was not statistically significant(P=0.317).Conclusion:The second-generation TKI flumatinib independently developed in China,has good curative effect and safety for CML-CP patients who failed first-line and second-line treatment.

AIM: To evaluate the efficacy and safety of foveal-sparing internal limiting membrane peeling(FSIP)or complete internal limiting membrane peeling(CMIP)for the treatment of myopic traction maculopathy(MTM)during vitrectomy.METHODS: CNKI, Wanfang, VIP, PubMed, Embase, Cochrane Library, and Web of Science were searched from January 1th 2000 to July 1th 2022, and studies that compared FSIP and CMIP for MTM were collected. The change and recovery rate of best corrected visual acuity(BCVA), incidence of full-thickness macular hole(FTMH), change of central foveal thickness(CFT)and the rate of complete reattachment.RESULTS: A total of 484 eyes from 12 literatures were included, with 203 eyes in the FSIP group and 281 eyes in the CMIP group.

There was no statistical difference between the two surgical methods in terms of mean change in CFT(SMD=0.04, 95%CI: -0.19～0.26, P=0.75)and the rate of complete reattachment(RR=1.12, 95%CI: 0.94～1.32, P=0.20).CONCLUSION: FSIP have similar anatomical outcomes compared to CMIP, but FSIP resulted in better visual acuity and lower incidence of postoperative FTMH.

Primary aldosteronism (PA) is the most common form of secondary hypertension, with its main manifestations including hypertension and hypokalemia. Early identification of PA is extremely important as PA patients can easily develop cardiovascular complications such as atrial fibrillation, stroke, and myocardial infarction. The past decade has witnessed the rapid advances in the genetics of PA, which has shed new light on PA treatment. While surgery is the first choice for unilateral diseases, bilateral lesions can be treated with mineralocorticoid receptor antagonists (MRAs). The next-generation non-steroidal MRAs are under investigations. New medications including calcium channel blockers, macrophage antibiotics, and aldosterone synthase inhibitors have provided a new perspective for the medical treatment of PA.

Objective: To establish and validate a nomogram-based predictive model for idiopathic hyperaldosteronism (IHA). Methods: This cross-sectional study was conducted with the collected clinical and biochemical data of patients with primary aldosteronism (PA) including 249 patients with unilateral primary aldosteronism (UPA) and 107 patients with IHA, who were treated at the Department of Endocrinology of the First Affiliated Hospital of Chongqing Medical University from November 2013 to November 2022. Plasma aldosterone concentration (PAC) and plasma renin concentration (PRC) were measured by chemiluminescence. Stepwise regression analysis was applied to select the key predictors of IHA, and a nomogram-based scoring model was developed. The model was validated in another external independent cohort of patients with PA including 62 patients with UPA and 43 patients with IHA, who were diagnosed at the Department of Endocrinology, First Affiliated Hospital of Zhengzhou University. An independent-sample t test, Mann-Whitney U test, and χ² test were used for statistical analysis. Results: In the training cohort, in comparison with the UPA group, the IHA group showed a higher serum potassium level [M(Q₁, Q₃), 3.4 (3.1, 3.8) mmol/L vs. 2.7 (2.1, 3.1) mmol/L] and higher PRC [4.0 (2.1, 8.2) mU/L vs. 1.5 (0.6, 3.4) mU/L] and a lower PAC post-saline infusion test (SIT) [305 (222, 416) pmol/L vs. 720 (443, 1 136) pmol/L] and a lower rate of unilateral adrenal nodules [33.6% (36/107) vs. 81.1% (202/249)]; the intergroup differences in these measurements were statistically significant (all P<0.001). Serum potassium level, PRC, PAC post-SIT, and the rate of unilateral adrenal nodules showed similar performance in the IHA group in the validation cohort. After stepwise regression analysis for all significant variables in the training cohort, a scoring model based on a nomogram was constructed, and the predictive parameters included the rate of unilateral adrenal nodules, serum potassium concentration, PAC post-SIT, and PRC in the standing position. When the total score was ≥14, the model showed a sensitivity of 0.65 and specificity of 0.90 in the training cohort and a sensitivity of 0.56 and specificity of 1.00 in the validation cohort. Conclusion: The nomogram was used to successfully develop a model for prediction of IHA that could facilitate selection of patients with IHA who required medication directly.
