RESUMEN
Alloying lanthanide ions (Yb3+) into perovskite quantum dots (Yb3+:CsPb(Cl1-xBrx)3) is an effective method to achieve efficient near-infrared (NIR) luminescence (>950 nm). Increasing the Yb3+ alloying ratio in the perovskite matrix enhances the luminescence intensity of Yb3+ emission at 990 nm. However, high Yb3+ alloying (>15%) results in vacancy-induced inferior material stability. In this work, we developed a polarity-mediated antisolvent manipulation strategy to resolve the incompatibility between a high Yb3+ alloying ratio and inferior stability of Yb3+:CsPb(Cl1-xBrx)3. Precise control of solution polarity enables increased uniformity of the perovskite matrix with fewer trap densities. Employing this strategy, we obtain Yb3+:CsPb(Cl1-xBrx)3 with the highest Yb3+ alloying ratio of 30.2% and a 2-fold higher electroluminescence intensity at 990 nm. We lever the engineered Yb3+:CsPb(Cl1-xBrx)3 to fabricate NIR-LEDs, achieving a peak external quantum efficiency (EQE) of 8.5% at 990 nm: this represents the highest among perovskite NIR-LEDs with an emission wavelength above 950 nm.
RESUMEN
PURPOSE: Currently, postoperative wound infection and poor healing of total knee arthroplasty have been perplexing both doctors and patients. We hereby innovatively invented a new dressing system to reduce the incidence of postoperative wound complications. METHODS: We enrolled 100 patients who received primary unilateral total knee arthroplasty and then applied the new dressing system. The data collected included the number of dressing changes, postoperative hospital stay, Visual Analogue Scale score (VAS), the Knee Society Score (KSS), the Knee Injury and Osteoarthritis Outcome Score (KOOS), ASEPSIS scores, The Stony Brook Scar Evaluation Scale (SBSES), wound complications, dressing cost, the frequency of shower and satisfaction. Subsequently, a statistical analysis of the data was performed. RESULTS: Our findings demonstrated the average number of postoperative dressing changes was 1.09 ± 0.38, and the average postoperative hospital stay was 3.72 ± 0.98 days. The average cost throughout a treatment cycle was 68.97 ± 12.54 US dollars. Collectively, the results of VAS, KSS, and KOOS revealed that the pain and function of patients were continuously improved. The results of the four indexes of the ASEPSIS score were 0, whereas the SBSES score was 3.58 ± 0.52 and 4.69 ± 0.46 at two weeks and one month after the operation, respectively. We observed no wound complications until one month after the operation. Remarkably, the satisfaction rate of the patients was 91.85 ± 4.99% one month after the operation. CONCLUSION: In this study, we invented a new dressing system for surgical wounds after total knee arthroplasty and further confirmed its clinical feasibility and safety.

Background: The traditional audiovisual sexual stimulation (AVSS) test may experience limitations including low erectile response rate and lack of unified diagnostic criteria. Aim: We aimed to explore the clinical value of AVSS with virtual reality (VR-AVSS) test in assessing erectile function and diagnosing erectile dysfunction (ED). Methods: Participants 18 to 60 years of age were screened for analysis in 3 clinical centers from June 2020 to March 2022. Demographic data, 5-item International Index of Erectile Function (IIEF-5), erectile hardness score (EHS), and self-reported symptom questions were collected. The ED patients and control patients were confirmed according to the IIEF-5 and EHS. All subjects watched a 60-minute erotic video by VR device during RigiScan recording. The parameters including tip average rigidity, tip effective erectile duration (duration of rigidity ≥60%, tip effective erectile duration), base average rigidity, and base effective erectile duration were evaluated. Outcomes: The main outcome of interest was the application of VR immersion technology to improve the traditional AVSS test. Results: A total of 301 ED cases and 100 eligible control patients were included for final analysis. Compared with control patients, ED cases had significantly lower IIEF-5 scores, EHS, positive response rate, and erectile rigidity and duration. The positive response rate of ED and control patients were 75.5% and 90.9%, respectively. The cutoff points of tip average rigidity, tip effective erectile duration, base average rigidity, and base effective erectile duration were 40.5% (sensitivity: 77.6%, specificity: 70.2%; P < .001), 4.75 minutes (sensitivity: 75.9%, specificity: 75.4%; P < .001), 48.5% (sensitivity: 77.6%, specificity: 75.1%; P < .001), and 7.75 minutes (sensitivity: 79.3%, specificity: 75.7%; P < .001). Clinical Implications: The technological superiority of VR will enable the VR-AVSS immersion test to be a more accurate detection than traditional AVSS modes. Strengths and Limitations: Our study applied VR immersion technology to establish the standard operation procedure for the AVSS test, which could effectively reduce the interference of adverse factors and minimize the detecting errors. However, the test data only included positive response subjects, so the true erectile status of men with a negative response to the AVSS test cannot be obtained. Conclusions: The VR-AVSS test can effectively improve the diagnostic accuracy of ED. The average rigidity and effective erectile duration were the optimal diagnostic parameters for excluding ED.
RESUMEN
BACKGROUND: A 32-year-old male patient was diagnosed with a 30% left pneumothorax on November 5, 2020, during which chest imaging indicated abnormalities. Despite this, pulmonary tuberculosis (TB) was not diagnosed or treated at that time due to a negative result in the MGIT960 culture. The patient experienced symptoms of cough and expectoration on April 24, 2022. Upon repeating the chest imaging, the condition had worsened, confirming the presence of pulmonary TB, leading to the patient's hospitalization. On September 1, 2022, the 11-year-old daughter of the patient was diagnosed with pulmonary tuberculosis accompanied by bronchial tuberculosis and tuberculous pleurisy. METHODS: The diagnosis of pulmonary tuberculosis was confirmed through sputum smears and Gene Xpert MTB/RIF testing, for the patient and his 11-year-old daughter in 2022. The patient underwent a 6-month combination therapy (2HRZE/4HR) comprising isoniazid, rifampicin, pyrazinamide, and ethambutol. His daughter with pulmonary tuberculosis accompanied by bronchial tuberculosis and tuberculous pleurisy underwent a 12-month combination therapy. RESULTS: Late diagnosis and treatment delays contribute to tuberculosis infections within families. Fortunately, after more than 3 months of antituberculosis treatment, the patient experienced relief from cough and sputum secretion, and there was improvement observed in the chest CT scan. Six months later, the patient was successfully cured of TB. 12 months later, his daughter also was successfully cured of TB. CONCLUSION SUBSECTIONS: Early diagnosis and treatment of tuberculosis (TB) is vital to reduce transmission, morbidity, and mortality.

BACKGROUND: Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) significantly improve the survival of patients with Epidermal growth factor receptor (EGFR) sensitive mutations in non-small cell lung cancer (NSCLC). CASE SUMMARY: A 67-year-old female patient in advanced lung adenocarcinoma suffered from drug resistance after EGFR-TKIs treatment. Secondary pathological tissue biopsy confirmed squamous cell carcinoma (SCC) transformation. Patients inevitably encountered drug resistance issues after receiving EGFR-TKIs treatment for a certain period of time, while EGFR-TKIs can significantly improve the survival of patients with EGFR-sensitive mutations in NSCLC. Notably, EGFR-TKIs resistance includes primary and acquired. Pathological transformation is one of the mechanisms of acquired resistance in EGFR-TKIs, with SCC transformation being relatively rare. Our results provide more detailed results of the patient's diagnosis and treatment process on SCC transformation after EGFR-TKIs treatment for lung adenocarcinoma. CONCLUSION: Squamous cell carcinoma transformation is one of the acquired resistance mechanisms of EGFR-TKIs in advanced lung adenocarcinoma with EGFR mutations.
RESUMEN
Epigallocatechin-3-gallate (EGCG) is an important tea polyphenol with anti-tumor potential. Our previous studies revealed that EGCG was a promising immune checkpoint inhibitor (ICI) as it could downregulate expression of programmed cell death 1 ligand 1 (PD-L1) in tumor cells, thereby resulting tumor killing effect. In particular, EGCG can effectively avoid the inflammatory storm caused by anti-tumor therapy, which is a healthy green capacity absent from many ICIs. However, the relationship between EGCG and programmed cell death 1 (PD-1) of T cells remains unclear. In this work, we explored the effect of EGCG on T cells and found that EGCG suppressed PD-1 via inhibiting NF-κB phosphorylation and nuclear translocation. Furtherly, the capability of EGCG was confirmed in tumor-bearing mice to inhibit PD-1 expression in T cells and enhance apoptosis in tumor cells. These results implied that EGCG could inhibit the expression of PD-1 in T cells, thereby promoting anti-tumor effects of T cells. EGCG will be a promising candidate in anti-tumor therapy.

Objective:To explore the clinical efficacy and safety of modified Heweitang in the treatment of functional dyspepsia (FD) due to liver-stomach disharmony and its regulation of gastrointestinal hormones and brain-gut peptides. Method:One hundred and twenty-six eligible patients were randomized into a control group (62 cases) and an observation group (64 cases). Patients in the observation group took the modified Heweitang granules with warm water 30 min after meals, 10 g/time, 3 times/day, while those in the control group took the corresponding placebo granules at the same dose in the same manner. The treatment in both groups lasted for four weeks. Before and after treatment, the four main symptoms including postprandial satiety, early satiety, upper abdominal pain, and upper abdominal burning sensation were scored, followed by the examination of gastric emptying (GE) and the scoring of the functional digestive disorders quality of life questionnaire (FDDQL), 7-point global overall symptom scale (GOSS), and liver-stomach disharmony syndrome. The cholecystokinin (CCK), motilin (MTL), gastrin (GAS), serotonin (5-HT), vasoactive intestinal peptide (VIP), and substance P (SP) levels before and after treatment were detected, and then the safety was evaluated. Result:After treatment, the scores of the four main symptoms, GOSS, and liver-stomach disharmony syndrome in the observation group were lower than those in the control group (<italic>P</italic><0.01), while the GE rate and FDDQL scores in the observation group were higher (<italic>P</italic><0.01). The CCK, GAS, 5-HT, and VIP levels of the observation group declined as compared with those of the control group (<italic>P</italic><0.01), whereas the MTL and SP levels were elevated (<italic>P</italic><0.01). After treatment, the overall response rate in the observation group was (51/57)89.47%, higher than (15/56)26.79% in the control group (<italic>χ</italic><sup>2</sup>=45.696, <italic>P</italic><0.01). No drug-related adverse reactions were found during the trial. Conclusion:The modified Heweitang is efficient and safe in relieving the main and related symptoms and traditional Chinese medicine (TCM) syndrome, regulating the secretion of gastrointestinal hormones and brain-gut peptides, promoting GE rate, and improving the quality of life of patients with FD due to liver-stomach disharmony.

RESUMEN
OBJECTIVE@#To investigate the synergistic effect and mechanism of the combined application of recombinant human bone morphogenetic protein-2 (rhBMP-2) and basic fibroblast growth factor (bFGF).@*METHODS@#24 KM male mice were randomly divided into 6 groups with 4 mice in each group, namely, Group A (control group), Group B (only treated with collagen), Group C (treated with 2 ng bFGF+collagen), Group D (treated with 4 μ g rhBMP-2+collagen), Group E (treated with 4 μ g rhBMP-2+2 ng bFGF+collagen) and Group F (treated with 4 μ g rhBMP-2+4 ng bFGF+collagen). The composites were implanted into the intermuscular septum of hind legs mice; whereas in control group, intermuscular septum of mice was separated and no implantation was performed. General observation, detection of concentration of calcium content, micro computed tomography (Micro-CT), three-dimensional reconstruction scan, measurement of bone mineral density (BMD), bone volume fraction (BVF) and trabecular thickness (Tb.Th), as well as histological observation with HE staining and ALP and CD34 immumohistochemical staining were performed.@*RESULTS@#Ectopic osteogenesis was found in Groups D, E and F mice. The difference in concentration of calcium contents was statistically significant between Groups D and E (P0.05). Micro-CT and three-dimensional reconstruction revealed continuous newborn bone substance in external surface of ectopic bone formation, and the center of bone formation did not show obvious substantial filling by bone substance. The differences in BMD, BVF and Tb.Th were statistically significant between Groups D and E or F (P<0.01 or <0.05). HE staining showed that in Groups D, E and F, newborn bone substance was mainly located at the edge of ectopic bone formation, and the bone formation in Groups E and F was better than that in Group D. ALP and CD34 immumohistochemical staining revealed the positive expression mainly at the edge of ectopic bone formation, and area of positive expression in Groups E and F was larger than that in Groups D.@*CONCLUSIONS@#rhBMP-2 possesses the capacity to induce ectopic osteogenesis independently, but bFGF does not have this ability; the combined application of rhBMP-2 and bFGF can enhance the synergetic effect on inducing ectopic osteogenesis.

RESUMEN
Flavonol synthase (FLS) is one of the key enzymes in flavonoids metabolic pathways. In this study, middle sequence was obtained from Carthamus tinctorius transcriptome sequencing results. Full-length cDNAs of FLS was cloned from petals of C. tinctorius to FLS by using RT-PCR and RACE technology. Its full-length cDNA was 1,201 bp, with an open reading frame of 1,101 bp and 336 encoded amino acids. The phylogenetic analysis showed that, FLS gene encoded amino acids in C. tinctorius were highly homologous with amino acids in congeneric Compositae species, especially Rudbeckia laciniata. The pBASTA-FLS plant expression vector was successfully built by the molecular biology method, which lays a foundation for further studying biology functions of the gene and biosynthesis mechanism of flavonoids.
