Objective:To evaluate the role of whole exome sequencing(WES)in the etiological diagnosis and precision medicine management of patients with urolithiasis.Methods:We conducted a retrospective review of 21 patients with urolithiasis and pathogenic gene mutations identified by WES at The Second Affiliated Hospital of Zhengzhou University between April 2019 and March 2025. The cohort included 13 males and 8 females,with a mean age of(18.9 ± 11.1)years;18 patients were under 25 years old. Clinical presentations included nephrocalcinosis(8 patients)and urinary tract calculi(13 patients),with five patients exhibiting extra-renal manifestations such as renal tubular acidosis and hyperaldosteronism. Stone composition analysis identified calcium oxalate(16 patients),cystine(4 patients),and carbonate apatite(1 patient). Metabolic abnormalities were prevalent,including hypocitraturia(11 patients),hyperoxaluria(8 patients),and hypercalciuria(7 patients),with eight patients presenting two or more concurrent disorders. All patients underwent WES and comprehensive metabolic evaluation. Sequencing was performed on an Illumina Hiseq4000 platform,achieving a mean depth of > 100× and coverage of > 98% in target regions. Variants were classified according to the American College of Medical Genetics and Genomics(ACMG)guidelines.Results:WES identified 12 distinct genes across autosomal recessive(9 genes: AGXT, GRHPR, ATP6V1B1, SLC12A1, KCNJ1, SLC3A1, SLC7A9, SLC34A3, WFS1),autosomal dominant(2 genes: CASR, ADCY10),and X-linked recessive(1 gene: CLCN5)inheritance patterns. Genotype-phenotype correlations revealed mutations associated with primary hyperoxaluria(8 patients),hypercalciuria(7 patients),and renal malformation due to a WFS1 mutation(1 patient). A positive genetic diagnosis was achieved in 100% of patients with either urinary oxalate > 1 000 μmol/24 h or cystine stones. 8 patients received a diagnosis of hereditary stone disease at their first presentation(non-delayed group),while 13 experienced a mean diagnostic delay of(9.6 ± 3.9)years. The delayed diagnosis group had a significantly older age at initial stone onset[(10.2 ± 5.3)years vs.(6.8 ± 3.1)years, P = 0.03]and a higher incidence of impaired renal function(6 patients vs. 1 patient, P = 0.04). Analysis of diagnostic delay by gene subgroup showed delays in 2/4 patients with cystinuria[ SLC3A1/ SLC7A9;(8.2 ± 3.5)years],5/8 with primary hyperoxaluria[ AGXT/ GRHPR;(10.5 ± 4.1)years],5/7 with hypercalciuria-related genes[ CASR/ ADCY10/ SLC12A1/ KCNJ1/ SLC34A3;(9.8 ± 3.8)years],and 1/2 with other genes[ ATP6V1B1/ WFS1/ CLCN5;(7.6 ± 2.2)years]. Among 32 mutation sites detected,21 were classified as pathogenic/likely pathogenic and 11 as variants of uncertain significance. Four novel mutations were identified: ATP6V1B1(presenting with renal tubular acidosis,nephrocalcinosis,and hypocitraturia), WFS1(presenting with renal malrotation,hydronephrosis,and stones without metabolic abnormalities), SLC12A1(presenting with Bartter syndrome type 1,chronic renal insufficiency,hypercalciuria,hypocitraturia,alkalosis,and hyperaldosteronism),and SLC3A1(presenting with bilateral renal stones and cystinuria). Conclusions:WES is crucial in identifying the underlying etiology of urolithiasis and can guide targeted treatment. We recommend early WES for patients with an initial stone presentation before age 25,those with nephrocalcinosis,or those with abnormal metabolic workups to facilitate precise diagnosis and preventive care.

Objective:To analyze the status of registration of clinical trials of radiopharmaceuticals in China, and to provide reference for the development and clinical application of radiopharmaceuticals.Methods:By searching the clinical trial registration and information disclosure platform of the Center for Drug Evaluation of the National Medical Products Administration (NMPA), the data on clinical trials of radiopharmaceuticals registered from 2014 to 2024 were collected and analyzed for trial design, administered dose, common indications, and geographical distribution.Results:A total of 77 clinical trials were included. The Compound Annual Growth Rate for the number of projects from 2014 to 2024 was 40%. Diagnostic radiopharmaceuticals were predominantly based on 18F and 99Tc m, while therapeutic radiopharmaceuticals primarily utilized 177Lu and 90Y. All indications were concentrated in the field of oncology. Regarding trial design, non-randomized (71.4%), open-label (89.6%), and single-arm (66.2%) trials accounted for the highest proportions. Geographical distribution showed Beijing (29 trials), Shanghai (18 trials), and Jiangsu province (14 trials) as the regions with the highest concentration of clinical trials. Conclusions:Radiopharmaceutical clinical trials in China have shown rapid growth. However, research remains predominantly focused on oncology, with a relatively high proportion of early-stage trials. In order to fully utilize the potentials of radiopharmaceuticals and improve the quality of clinical trials, nuclear medicine researches should broaden therapeutic applications, implement prudently administerd dose in clinical trials, and implement optimized radiation protection procedures across all clinical trial centers.

Objective:To summarize the best evidence for exercise intervention in elderly patients with sarcopenia in intensive care unit (ICU) through literature search, and provide a reference for clinical implementation of early exercise intervention in this population through evidence-based practice.Methods:① Summary of best evidence: relevant literature on exercise intervention for elderly patients with sarcopenia in ICU, including guideline, evidence summary, expert consensus, systematic review, and original study [quasi-experiment and randomized controlled trial (RCT)] from UpToDate Clinical Advisor, Ovid database, National Guideline Clearinghouse (NGC), National Institute for Health and Care Excellence (NICE), Cochrane Library, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed/Medline, SinoMed, CNKI, Wanfang Database, VIP, and Yimai Tong Guideline Network were systematically searched. The search period covered from the establishment of these databases up to August 24, 2023. The quality of the literature was evaluated by two researchers with methodological expertise in evidence-based medicine, and the evidences were extracted and summarized. ② Evidence-based practice: the elderly patients with high risk of sarcopenia who had been hospitalized in the ICU for more than 7 days from January to April 2024 were enrolled as the research subjects, and they were divided into a control group and an intervention group using convenience sampling method. The control group received routine intensive care nursing. The intervention group implemented exercise intervention based on the actual situation of the patients, the baseline review was conducted before evidence application, and the effectiveness of evidence application at 7 days and 14 days was evaluated.Results:① A total of 19 pieces of literature were included, including 4 guidelines, 1 summary of evidence, 4 expert consensuses, 4 systematic reviews, and 6 original studies (1 quasi-experiment, 5 RCT). After literature quality evaluation, all 19 articles were enrolled. Finally, 31 pieces of best evidence were extracted from eight aspects, including assessment and diagnosis, multidisciplinary cooperation, indication, preparation before intervention, intervention program, safety monitoring, post-intervention evaluation, and special task. ② Finally, a total of 30 patients were enrolled in the intervention group, of which 17 completed 14 days of rehabilitation exercise, and 13 completed 7 days of rehabilitation exercise. Twenty-seven patients were enrolled in the control group, of which 17 completed 14 days of monitoring, and 10 completed 7 days of monitoring. Clinical evidence application results showed that the patients in the intervention group did not experience adverse events such as increased heart rate, extubation, or physical discomfort. The skeletal muscle mass index (SMI) in both groups was gradually decreased with the prolongation of intervention duration, but the 7-day SMI in the intervention group was significantly higher than that in the control group (kg/m 2: 8.61±2.66 vs. 6.65±1.50, P < 0.01). Conclusion:By summarizing the best evidence and evidence-based practice of exercise intervention for elderly patients with sarcopenia in ICU, this study confirmed the feasibility due to safe and effective of implementing early exercise intervention for elderly sarcopenia patients in ICU.

Chinese Journal of Postgraduates of Medicine 2024;47(6):545-549
Objective:To investigate the relationship between serum microRNAs-27b (miR-27b) expression and major adverse cardiovascular events (MACE) after percutaneous coronary intervention (PCI) in patients with ST segment elevation myocardial infarction (STEMI).Methods:A total of 168 STEMI patients undergoing PCI treated in the Honghu People′s Hospital from February 2019 to April 2021 were selected as the observation group, and 154 healthy subjects who underwent physical examination during the same period were selected as the control group. The expression of serum miR-27b was detected by real-time fluorescence quantitative polymerase chain reaction (PCR), and the expression of serum miR-27b was compared between the two groups. The observation group was followed up for 6 months after PCI, and the occurrence of MACE was counted, and the patients were divided into the occurrence group and the non-occurrence group accordingly it, and the expression of serum miR-27b and general data of the two groups were compared. The influencing factors of MACE in STEMI patients after PCI was analyzed by using Logistic regression analysis method.Results:The expression of serum miR-27b in the observation group was higher than that in the control group : 2.26 ± 0.31 vs. 1.32 ± 0.26, P<0.05. During the 6-month follow-up period, there was no any loss of follow-up in 168 patients underwent PCI, and the incidence rate of MACE was 28.57%(48/168). The miR-27b expression in the occurrence group was higher than that in the non-occurrence group: 2.61 ± 0.49 vs. 2.13 ± 0.24, P<0.05. The results of multivariate Logistic regression analysis showed that history of diabetes mellitus, hypersensitive C-reactive protein, low left ventricular ejection fraction, high coronary Gensini score, high serum miR-27b expression, multi-vessel disease, degree of lesion stenosis grade Ⅲ to Ⅳ, and long duration of operation were independent risk factors for MACE in STEMI patients ( OR = 1.697, 2.680, 3.673, 2.121, 2.863, 1.846, 2.751, 3.007, P<0.05). Conclusions:The serum miR-27b in STEMI patients is abnormally high expression, which can increase the risk of MACE after PCI in STEMI patients.

The rapidly developing resistance of cancers to chemotherapy agents and the severe cytotoxicity of such agents to normal cells are major stumbling blocks in current cancer treatments. Most current chemotherapy agents have significant cytotoxicity, which leads to devastating adverse effects and results in a substandard quality of life, including increased daily morbidity and premature mortality. The death receptor of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) can sidestep p53-dependent pathways to induce tumor cell apoptosis without damaging most normal cells. However, various cancer cells can develop resistance to TRAIL-induced apoptosis via different pathways. Therefore, it is critical to find an efficient TRAIL sensitizer to reverse the resistance of tumor cells to TRAIL, and to reinforce TRAIL's ability to induce tumor cell apoptosis. In recent years, traditional Chinese medicines and their active ingredients have shown great potential to trigger apoptotic cell death in TRAIL-resistant cancer cell lines. This review aims to collate information about Chinese medicines that can effectively reverse the resistance of tumor cells to TRAIL and enhance TRAIL's ability to induce apoptosis. We explore the therapeutic potential of TRAIL and provide new ideas for the development of TRAIL therapy and the generation of new anti-cancer drugs for human cancer treatment. This study involved an extensive review of studies obtained from literature searches of electronic databases such as Google Scholar and PubMed. "TRAIL sensitize" and "Chinese medicine" were the search keywords. We then isolated newly published studies on the mechanisms of TRAIL-induced apoptosis. The name of each plant was validated using certified databases such as The Plant List. This study indicates that TRAIL can be combined with different Chinese medicine components through intrinsic or extrinsic pathways to promote cancer cell apoptosis. It also demonstrates that the active ingredients of traditional Chinese medicines enhance the sensitivity of cancer cells to TRAIL-mediated apoptosis. This provides useful information regarding traditional Chinese medicine treatment, the development of TRAIL-based therapies, and the treatment of cancer.

Objective:To study the clinicopathological features of metaplastic breast cancer (MBC) , and its prognostic factors.Methods:Data of 49 MBC cases and 30 cases of invasive ductal carcinoma (IDC) during the same period as matched control were collected. The immunohistochemistry staining of CK5/6, CK, P63, ER, HER2, Ki67 was performed in all MBC samples.Results:In MBC cases, the median age was 55 years. Median tumor size was 2.5 cm (range, 0.6-19 cm). Fifteen cases were classified as metaplastic carcinoma with heterologous mesenchymal differentiation (8 as matrix-producing carcinoma), 12 as spindle cell carcinoma, 7 as squamous cell carcinoma, 2 as low-grade adenosquamous carcinoma, 2 as fibromatosis-like metaplastic carcinoma, and 11 as mixed metaplastic carcinoma. The 5-, 10-year overall survival rate was 50%, 41%, respectively, lower than those of IDC (76%,63%) (all P<0.05). Lymph node metastasis rate, and expression of ER, PR, HER2 in MBC were lower than those in IDC (all P<0.05). Triple-negative cases in MBC were more than those of IDC ( χ2=26.244, P=0.000). The proliferative index of Ki67 was statistically different between the two groups ( t=2.624, P=0.011). Conclusions:MBC is a rare and heterogenous breast cancer. Compared to IDC, MBCs are usually larger, lower in lymph nodes metastasis, higher in proliferative index of Ki67, more triple-negative, hence with a poorer prognosis.
