OBJECTIVE: To analyze the current status and trends of the disease burden of knee osteoarthritis (KOA) in China from 1990 to 2023, and to examine the epidemiological characteristics of age, gender differences, and attribution to high body mass index (BMI), in order to provide a basis for formulating prevention and treatment strategies to reduce the disease burden of KOA in China. METHODS: Based on the 2023 Global Burden of Disease Study (GBD) database, data on the number, rate, and age-standardized rate of incidence, prevalence, disability-adjusted life years (DALYs) for KOA, and DALYs for KOA attributable to high BMI in the Chinese population from 1990 to 2023 were integrated. The Joinpoint 5.4.0.0 software was used to analyze the age and gender differences in KOA and the epidemiological characteristics attributable to high BMI. RESULTS: The standardized incidence, prevalence, and DALYs rates of KOA in China in 2023 increased by 6.46%, 6.43%, and 6.93%, respectively, compared with 1990. In terms of age, the disease burden of KOA in China was lowest in the age group of 30-34 years, with the highest incidence rate in the age group of 50-54 years, whereas the prevalence rate and DALYs rate continued to increase with age, and both were highest in the age group of ≥70 years. In terms of gender, all disease burden standardized rate indicators were higher in females than in males, and the difference widened with age. The rate of BMI-attributable DALYs increased at an annual average rate of 1.57% (95% CI: 1.55, 1.59) from 1990 to 2023, again with significant age and gender differences. CONCLUSION The continued growth of the KOA disease burden and significant population differences characterizing China call for focused attention on the female middle-aged and elderly population, enhanced weight management, and implementation of targeted preventive and control measures.

Mechanical pain is one of the most common causes of clinical pain, but there remains a lack of effective treatment for debilitating mechanical and chronic forms of neuropathic pain. Recently, neurotoxin GsMTx4, a selective mechanosensitive (MS) channel inhibitor, has been found to be effective, while the underlying mechanism remains elusive. Here, with multiple rodent pain models, we demonstrated that a GsMTx4-based 17-residue peptide, which we call P10581, was able to reduce mechanical hyperalgesia and neuropathic pain. The analgesic effects of P10581 can be as strong as morphine but is not toxic in animal models. The anti-hyperalgesic effect of the peptide was resistant to naloxone (an μ-opioid receptor antagonist) and showed no side effects of morphine, including tolerance, motor impairment, and conditioned place preference. Pharmacological inhibition of TRPV4 by P10581 in a heterogeneous expression system, combined with the use of Trpv4 knockout mice indicates that TRPV4 channels may act as the potential target for the analgesic effect of P10581. Our study identified a potential drug for curing mechanical pain and exposed its mechanism.

OBJECTIVE: To compare the prevalence of chromosomal aneuploidies and pregnancy outcomes of D5 and D6 blastocysts subjected to preimplantation genetic testing for aneuploidy (PGT-A). METHODS: Clinical and laboratory data of 268 couples who underwent PGT-A at the Reproductive Center of the First Affiliated Hospital of Zhengzhou University from September 2018 to September 2020 were collected. The prevalence of chromosomal aneuploidies and pregnancy outcomes of D5/D6 biopsied blastocysts were compared. RESULTS: Compared with D6 blastocysts, the euploidy rate of D5 blastocysts was significantly higher (49.1% vs. 41.1%, P = 0.001 1), whilst their aneuploidy rate was significantly lower (50.9% vs. 58.9%, P = 0.001 1). The rate of numerical abnormalities of D6 blastocysts was significantly higher than that of D5 blastocysts (27.9% vs. 20.2%, P = 0.000 5). For patients under 35 years old, the euploidy rate of D5 blastocysts was significantly higher than that of D6 blastocysts (53.8% vs. 44.3%, P = 0.001), whilst the numerical abnormality rate was significantly lower (16.3% vs. 23.9%, P = 0.001). For both D5 and D6 blastocysts, the euploidy rates for patients <= 35 were significantly higher than those for > 35. The elder group had the lowest rates for aneuploidies and live births. Compared with those receiving D6 blastocysts transplantation, the pregnancy rate, implantation rate and live birth rate for those receiving thawed D5 blastocysts transplantation were significantly higher (60.2% vs.37.0%, P = 0.000 3; 59.1% vs.37.0%, P = 0.000 6; 47.7% vs. 28.3%, P = 0.002). CONCLUSION For patients undergoing PGT-A, the chromosomal euploidy rate for D5 blastocysts is higher than that for D6 blastocysts, and the clinical outcome of D5 blastocysts with normal signal is better than that of D6 blastocysts. Elder patients have a higher rate of aneuploidies.

Objective To retrospectively compared the hospitalization days and hospitalization costs of patients with thyroid tumor and breast cancer between patients who accepted selective hospitalization management and patients who accepted routine hospital management, and analyze the effect of selective hospitalization management to shorten the average hospitalization days.Methods A total of 419 patients with thyroid tumor and 318 patients with breast cancer who were treated in Fujian Provincial Hospital from March 2013 to February 2016 were chosen as the study object, and they were divided into the control group and the study group according to whether accepting the selective hospitalization management. Evaluating indicators included the total hospitalization days, preoperative hospitalization days, postoperative hospitalization days and hospitalization costs.Results Compared with the control group, the average total hospitalization days [(6.56±2.94)d vs (8.09± 3.71)d,(12.44±3.91)d vs (14.73±6.66)d)] and preoperative hospitalization days[(2.42±1.94)d vs (4.17± 2.68)d,(2.98±1.70) vs (5.29±4.00)d] in the study group were all reduced (P<0.05). There was no significant difference in the postoperative hospitalization days and the average hospitalization costs between two groups ( P > 0. 05 ) . Conclusions Selective hospitalization management could effectively shorten the hospitalization days of patients undergoing selective operation, and increase beds turnover rate. So the new management method would produce good social and economic benefits for the hospital.

OBJECTIVETo investigate the effect of rapamycin, an mTOR inhibitor, on learning and memory ability of mice with pilocarpine (PILO)-induced seizure.

METHODSOne hundred and sixty male adult ICR mice were randomly grouped as vehicle control (n=20), rapamycin control (n=20), PILO model (n=40), rapamycin pre-treatment (n=40) and rapamycin post-treatment (n=40). PILO model and rapamycin treatment groups were injected with PILO to induce temporal lobe seizure. Rapamycin was administrated for 3 days before or after seizure. Morris water maze, Y maze and open field were used for the assessment of learning and memory, and FJB and Timm staining were conducted to detect the neuronal cell death and mossy fiber sprouting, respectively.

RESULTSNo significant cell death was observed in the mice with PILO-induced seizure. The learning and memory were impaired in mice 7 to 10 days after PILO-induced seizure, which was evident by prolongation of avoiding latency (P<0.05), decrease in number of correct reaction (P<0.01) and number of crossing (P<0.05). Treatment with rapamycin both pre-and post- PILO injection reversed seizure-induced cognitive impairment. In addition, rapamycin inhibited the mossy fiber sprouting after seizure (P<0.001).

CONCLUSIONRapamycin improves learning and memory ability in ICR mice after PILO-induced seizure, and its mechanism needs to be further studied.
