Anti-tumor traditional Chinese medicine has a long history of clinic application, in which the star molecules have always been the hotspot of modern drug research, but they are limited by the solubility, stability, targeting, bioactivity or toxicity of the monomer components of traditional Chinese medicine anti-tumor star molecules and other pharmacokinetic problems, which hinders the traditional Chinese medicine anti-tumor star molecules for further clinical translation and application. Currently, the nanosystems prepared by supramolecular technologies such as molecular self-assembly and nanomaterial encapsulation have broader application prospects in improving the anti-tumor effect of active components of traditional Chinese medicine, which has attracted extensive attention from scholars at home and abroad. In this paper, we systematically review the research progress in preparation of supramolecular nano-systems from anti-tumor star molecule of traditional Chinese medicine, and summarize the two major categories and ten small classes of carrier-free and carrier-based supramolecular nanosystems and their research cases, and the future development direction is put forward. The purpose of this paper is to provide reference for the research and clinical transformation of using supramolecular technology to improve the clinical application of anti-tumor star molecule of traditional Chinese medicine.

Objective To compare clinical effect between open reduction and fixation with cannulated screw and threaded rivet via posteromedial approach versus arthroscopic Endobutton plate fixation in treating posterior cruciate ligament avulsion fractures.Methods Clinical data of 38 patients with posterior cruciate ligament avulsion fractures from July 2020 to December 2021 were analyzed retrospectively,and divided into open reduction and internal fixation group(posterior medial approach hollow anchor system fixation)and arthroscopic fixation group(Endobutton with loop plate fixation under arthroscopy).There were 20 patients in open reduction and internal fixation group,including 16 males and 4 females,aged from 26 to 74 years old with an average of(42.9±18.8)years old;13 patients on the left side and 7 patients on the right side;12 patients were classi-fied to type Ⅱ and 8 patiens with type Ⅲ according to Meyers-McKeever fractures classification;14 patients were grade Ⅱ and 6 patients were grade Ⅲ in back drawer test.There were 18 patients in arthroscopic fixation group,including 11 males and 7 fe-males;aged from 24 to 70 years old with an average of(53.5±13.4)years old;11 patients on the left side and 7 patients on the right side;10 patients were classified to type Ⅱ and 8 patiens with type Ⅲ according to Meyers-McKeever fractures classifica-tion;11 patients were grade Ⅱ and 7 patients were grade Ⅲ in back drawer test.Operation time,blood loss,and quality of im-mediate reduction were compared between two groups.Knee range of motion,knee back drawer test,and International Knee Documentation Committee(IKDC)grading,KT2000 stability evaluation and Lysholm function score of knee joint were com-pared at 6 months after operation.Results All patients were followed up for 8 to 16 months with an average of(12.3±1.9)months.There were no complications such as incision infection,fracture malunion or non-union,and internal fixation loosening occurred.The avulsion fractures of knee joint were reached to imaging healing standard at 6 months after operation.Operation time and blood loss in open reduction and internal fixation group were(56.4±7.1)min and(63.2±10.2)ml,while(89.9±7.4)min and(27.7±8.7)ml in arthroscopic fixation group,respectively,and had significant difference between two groups(P＜0.05).There were no differences in immediate reduction quality(x2=0.257,P=0.612),knee joint range of motion at 6 months after opertaion(t=0.492,P=0.626),knee joint rear drawer test(x2=0.320,P=0.572),IKDC classification of knee joint(x2=0.127,P=0.938),KT2000stability evaluation(x2=0.070,P=0.791),and knee Lysholmfunction score(t=0.092,P=0.282)between two groups.Conclusion Posterior medial approach with hollow anchoring system fixation and arthroscopic Endobutton with loop plate fixa-tion for the treatment of posterior cruciate ligament tibial occlusion avulsion fracture could achieve satisfactory clinical results,and arthroscopic surgery has less bleeding,but also has a longer learning curve and longer operation time than traditional inci-sion surgery.The surgeon needs to make a choice according to clinical situation of patient and their own surgical inclination.

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.

Aim To investigate the mechanism by which ginsenoside Rgl regulates autophagy anrl delays brain aging in mice through AMPK/mTOR signaling pathway.Methods C57BL/6J male mice were ran¬domly divided into four groups, namely brain aging model group ,control group, Rgl anti-aging group,auto¬phagy activator Rapamycin anti-aging group.After the modeling was completed, the test of each experimental index would be carried out on the next day.Morris wa¬ter maze experiment was used to detect the learning and memory ability of mice.Paraffin sections of the hippocampus were prepared, HE , Nissl and immunohis- tochemical staining were used to observe the morpholo¬gy of hippocampal neurons, the number of neurons and Nissl bodies was counted, and autophagy-related proteins p62 , ATG5 , ULK1 were detected.Brain tissue homogenates were prepared to detect the aetivity of brain tissue acetylcholinesterase ( AChE ).Western blot was userl to detect brain tissue autophagy-related proteins LC3II, P62, beclinl, P-AMPK/AMPK, P- mTOR/mTOR and apoptosis protein P53.Results Water maze test showed that Rgl and Hap significantly improved the learning and memory abilities of brain-ag¬ing mice.HE and Nissl staining showed that Rgl and Rap decreased necrotic cells and increased the number of Nissl bodies in the hippocampus of brain-aging mice.Immunohistochemistry staining showed that Rgl and Rap decreased the expression of neuronal autoph- agv protein P62 in hippocampus and increased the ex-pression of ATG5 and ULK1.Rgl and Rap decreased the activity of AhcE in brain-aging mice.Western blot showed that Rgl and Rap increased autophagy-related proteins LC3II, Beclinl , P-AMPK/AMPK, but de¬creased the expression of P-mTOR/mTOR, P62, P53.Conclusions Ginsenoside Rgl can effectively antago¬nize the aging effect of D-gal on mouse brain.The pos¬sible mechanism is related to the regulation of autoph- agv by Rgl through AMPK/mTOR signaling pathway.

OBJECTIVE: To investigate the clinical effect of double plate combined with iliac bone graft in the treatment of femoral nonunion after intramedullary nailing. METHODS: From December 2008 to December 2017, double plate combined with autogenous iliac bone graft was used to treat femoral nonunion after intramedullary nailing. There were 11 cases, including 10 males and 1 female, aged 35 to 62 years, and the time from fracture to nonunion was 12 to 20 months. According to Judet classification, there were 8 cases of atrophic nonunion and 3 cases of proliferative nonunion. Regular follow-up was conducted after operation to record the fracture healing time, load-bearing activity time and complications, and to observe the repair effect of double plate fixation combined with iliac bone graft on nonunion after femoral shaft fracture operation. RESULTS: All patients were followed up for 12 to 22 months. The operation time was 70 to 130 min and the blood loss was 180 to 350 ml. After operation, 2 cases had knee stiffness, which recovered after passive exercise with CPM machine for 2 weeks;1 case had pain in iliac bone donor area, which was relieved after 3 months. The time of fracture healing was 24 to 40 weeks, and the time of complete weight-bearing activity was 14 to 32 weeks. SF-36 quality of life score at the final follow-up:body pain 70 to 82, activty 70 to 82, social function 72 to 83, the overall health 72 to 82. At the end of the follow-up, there were no complications such as limb shortening, infection, poor wound healing, internal fixation failure (fracture, loosening). CONCLUSION It is an effective method to treat nonunion of femur after intramedullary nailing by using double plate combined with autogenous iliac bone graft.

Background/Aims: The mucoprotective drug rebamipide is used to treat gastritis and peptic ulcers. We compared the efficacy of Mucosta Ⓡ (rebamipide 100 mg) and its new formulation, AD-203 (rebamipide 150 mg), in treating erosive gastritis. Methods: This double-blind, active control, noninferiority, multicenter, phase 3 clinical trial randomly assigned 475 patients with endoscopically proven erosive gastritis to two groups: AD-203 twice daily or Mucosta Ⓡ thrice daily for 2 weeks. The intention-to-treat (ITT) analysis included 454 patients (AD-203, n=229; Mucosta Ⓡ , n=225), and the per-protocol (PP) analysis included 439 patients (AD-203, n=224; Mucosta Ⓡ , n=215). The posttreatment assessments included the primary (erosion improvement rate) and secondary endpoints (erosion and edema cure rates; improvement rates of redness, hemorrhage, and gastrointestinal symptoms). Drug-related adverse events were evaluated. Results: According to the ITT analysis, the erosion improvement rates (posttreatment) in AD-203-treated and Mucosta Ⓡ -treated patients were 39.7% and 43.8%, respectively. According to the PP analysis, the erosion improvement rates (posttreatment) in AD-203-treated and Mucosta Ⓡ -treated patients were 39.3% and 43.7%, respectively. The one-sided 97.5% lower limit for the improvement rate difference between the study groups was −4.01% (95% confidence interval [CI], –13.09% to 5.06%) in the ITT analysis and −4.44% (95% CI, –13.65% to 4.78%) in the PP analysis. The groups did not significantly differ in the secondary endpoints in either analysis. Twenty-four AD-203-treated and 20 Mucosta Ⓡ -treated patients reported adverse events but no serious adverse drug reactions; both groups presented similar adverse event rates. Conclusions The new formulation of rebamipide 150 mg (AD-203) twice daily was not inferior to rebamipide 100 mg (Mucosta Ⓡ ) thrice daily. Both formulations showed a similar efficacy in treating erosive gastritis.

OBJECTIVE: To explore the clinical effect of bio lengthened stem arthroplasty replacement in the treatment of unstable intertrochanteric fractures in the elderly. METHODS: From January 2015 to January 2018, 64 elderly patients with unstable intertrochanteric fractures were analyzed retrospectively. According to the surgical treatment, patients were divided into arthroplasty replacement group (bio-lengthened stem arthroplasty replacement) and internal fixation group (PFNA). In the arthroplasty group, there were 34 cases, including 19 males and 15 females, with an average age of (81.32±3.81) years old. The Evans classification of fracture was type Ⅲ in 15 cases, type Ⅳ in 16 cases and type Ⅴ in 3 cases. In the internal fixation group, there were 30 cases, including 14 males and 16 females, with an average age of (79.90±3.61) years old. The Evans classification of fracture was type Ⅲ in 10 cases, type Ⅳ in 15 cases and type V in 5 cases. X ray and CT showed unstable intertrochanteric fracture of femur. The operation time, intraoperative blood loss and complications were observed. Harris hip function score and SF-36 life quality score were used to evaluate the clinical effect. RESULTS: All the incisions healed in stage Ⅰ. All patients were followed up for 13 to 39 months with an average of 23.4 months. The operation time and bleeding volume of the patients in the arthroplasty replacement group were more than those in the internal fixation group (<0.05). At the final follow-up, Harris function score of hip joint in the arthroplasty group was better than that in the internal fixation group (< 0.05);SF-36 life quality score in the arthroplasty group was better than that in the internal fixation group (<0.05). CONCLUSION The treatmentof unstable intertrochanteric fractures with bio-lengthened stem arthroplasty replacement and internal fixation can achieve good clinical results, but with bio-lengthened stem arthroplasty replacement, the postoperative complications are less, the function of hip joint is better, and the life quality and satisfaction of patients are higher.

OBJECTIVE: To investigate the guiding significance of lumbar quantitative computed tomography (QCT) in percutaneous vertebroplasty (PKP) for osteoporotic vertebral compression fractures (OVCF). METHODS: The clinical data of 90 patients with OVCF underwent PKP from December 2017 to December 2018 were retrospectively analyzed. There were 24 femalesand66males, withanaverage agedof (74.47±6.60) yearsold. Allpatientswere received QCT examination before surgery, andaccording to the QCT value oflumbarspine, the patientswere dividedinto osteopenia decrease group (80 to 120 g/L, 17 cases, 30 vertebrae), osteoporosis group (40 to 80 g/L, 44 cases, 66 vertebrae) and severe osteoporosis group (<40 g/L, 29 cases, 39 vertebrae). Bone cement was injected into vertebral body, AP and lateral X-rays were done during operation. The diffusion and leakage of bone cement in injured vertebrae of patients with different QCT values were observed. Unilateral approach was used for patients whose bone cement diffused beyond the midline of the vertebral body, otherwise, and bilateral approach was adopted, and guiding significance of QCT in PKP for OVCF was analyzed. RESULTS: In 90 cases of 135 vertebrae, 72 cases of 98 vertebral bone cement diffused beyond the midline, accounting for 72.59%. Unilateral approach was used for the 72 patients whose bone cement diffused beyond the midline of the vertebral body, among them, there were 5 cases with 8 vertebrae in osteopenia group, 40 cases with 55 vertebrae in osteoporosis group and 27 cases with 35 vertebrae in severe osteoporosis group. There was significant difference in the bone cement dispersion between three groups (=41.397, =0.000). Moreover, no bone cement leakage occurred in osteopenia group, 3 cases of 4 vertebrae occurred in osteoporosis group and 2 cases of 3 vertebrae in severe osteoporosis group. However, none of the patients with bone cement leakage caused nerve injury and other symptoms, and there was no significant difference in bone cement leakage between the three groups (=2.242, =0.326). CONCLUSION According to the QCT examination of lumbar spine, defining the degree of osteoporosis and guiding the puncture method can shorten the operation time, reduce the number of fluoroscopy, and effectively improve the safety of vertebroplasty.

PURPOSE: Head and neck squamous cell carcinoma (HNSCC) is a deadly disease in which precision medicine needs to be incorporated. We aimed to implement next-generation sequencing (NGS) in determining actionable targets to guide appropriate molecular targeted therapy in HNSCC patients. MATERIALS AND METHODS: Ninety-three tumors and matched blood samples underwent targeted sequencing of 244 genes using the Illumina HiSeq 2500 platform with an average depth of coverage of greater than 1,000×. Clinicopathological data from patients were obtained from 17 centers in Korea, and were analyzed in correlation with NGS data. RESULTS: Ninety-two of the 93 tumors were amenable to data analysis. TP53 was the most common mutation, occurring in 47 (51%) patients, followed by CDKN2A (n=23, 25%), CCND1 (n=22, 24%), and PIK3CA (n=19, 21%). The total mutational burden was similar between human papillomavirus (HPV)–negative vs. positive tumors, although TP53, CDKN2A and CCND1 gene alterations occurred more frequently in HPV-negative tumors. HPV-positive tumors were significantly associated with immune signature-related genes compared to HPV-negative tumors. Mutations of NOTCH1 (p=0.027), CDKN2A (p < 0.001), and TP53 (p=0.038) were significantly associated with poorer overall survival. FAT1 mutations were highly enriched in cisplatin responders, and potentially targetable alterations such as PIK3CA E545K and CDKN2A R58X were noted in 14 patients (15%). CONCLUSION: We found several targetable genetic alterations, and our findings suggest that implementation of precision medicine in HNSCC is feasible. The predictive value of each targetable alteration should be assessed in a future umbrella trial using matched molecular targeted agents.

Irisin is a circulating myokine induced by exercise, which is a cleaved version of fibronectin type III domain containing protein 5 (FNDC5). It can promote the browning of white fat tissue, increase energy consumption, and decrease weight. Irisin plays an important role in the regulation of various diseases, such as diabetes and coronary heart disease. Different types of exercise have different effects on irisin level in blood circulation, and moderate exercise can reduce cardiovascular symptoms. In this paper, the cardiovascular protective effect of irisin and its research progress in the field of exercise are reviewed, hoping to provide a new target for the prevention and treatment of cardiovascular diseases.
