Objective:With the aging of the population, the health of women's ovarian in China has received increasing attention.Ovarian aging not only affects reproductive health but also increases the risk of chronic diseases.This study aims to systematically explore the relationship between living habits and ovarian aging.Methods:Based on the data from the China Health and Retirement Longitudinal Study(CHARLS)from 2011 to 2018, 8 287 postmenopausal women were included.A retrospective cohort study was conducted using statistical analysis and machine learning methods to evaluate the impact of lifestyle factors such as smoking, drinking, sleep, and dietary patterns on the age of menopause.Results:It was found that adverse lifestyle factors such as reduced daily meal frequency [the early menopause group(2.85±0.38)times/day vs.the normal group(2.89±0.38)times/day, P=0.002], smoking [the smoking rate of the early menopause group(7.75%) vs.that of the normal group(6.15%), P=0.004], and high-frequency drinking [the early menopause rate of people who drink daily(19.76%(33/167)) vs.that of people who rarely or never drink(14.62%(1 162/7 949)), P=0.047]were associated with accelerated ovarian aging. Conclusions:Reasonable adjustment of living habits maybe help to delay the age of menopause and reduce related health risks.This study provides a scientific basis for optimizing women's healthy lifestyles, which is conducive to improving the quality of life and happiness of middle-aged and elderly women in China.

Objective:To analyze the clinical efficacy and safety of carglumic acid in the treatment of neonatal hyperammonemia caused by organic acidemia.Methods:A case summary was made.Six cases of neonatal hyperammonemia caused by organic acidemia treated at the Neonatal Intensive Care Unit of Henan Children′s Hospital from March to September in 2024 were included.They received comprehensive ammonia-lowering treatment in combination with oral carglumic acid dispersible tablets.The clinical data of the children were collected and analyzed retrospectively.Changes in blood ammonia levels, blood gas parameters, and complete blood count before and after treatment with carglumic acid were analyzed using the Wilcoxon test.The incidence of adverse reactions and clinical regression during the treatment with carglumic acid was observed.Results:There were 2 females and 4 males in the 6 patients included.Four children suffered from isolated methylmalonic acidemia caused by MUT gene mutations, and the other 2 had propionic acidemia.The clinical manifestations were poor breastfeeding in 6 cases, vomiting in 2 cases, poor response in 6 cases, weight loss in 6 cases, and convulsions in 3 cases.Acute metabolic decompensation abnormalities were presented in all children, such as metabolic acidosis, hyperammonemia, leukopenia and thrombocytopenia.The first dose of carglumic acid was 62-255 mg/kg, the second dose was 75-172 mg/kg.The blood ammonia level decreased from 411.7 (339.7, 623.8) μmol/L before treatment to 108.1 (35.5, 229.1) μmol/L after 48 hours of treatment, showing a statistically significant reduction ( Z=2.20, P<0.05).Three cases with a blood ammonia level higher than 400 μmol/L, it was effectively reduced after treatment with carglumic acid.Two cases did not undergo hemodialysis or peritoneal dialysis.One case underwent hemodialysis but died after withdrawing the treatment.After administration of carglumic acid, metabolic acidosis was corrected in all children, and 2 patients ultimately died after discontinuing the treatment.No causal relationship was identified between adverse events and carglumic acid treatment.The examinations at discharge and during the follow-up period (2-7 months) showed that most laboratory abnormalities (including leukopenia, anemia, thrombocytopenia, hyperlactatemia, hyponatremia, hyperkalemia, elevated myocardial enzymes, and hyperbilirubinemia) returned to normal. Conclusions:Carglumic acid can effectively reduce neonatal hyperammonemia caused by organic academia, improve metabolic disorders, and reduce the need for blood purification or peritoneal dialysis, with good safety.

Chemotherapy based on cisplatin or its combination therapy is a common cancer treatment method.However,the non-specific side effects of cisplatin,poor pharmacokinetic properties of small molecule drugs,and susceptibility to drug resistance greatly limit the clinical application of cisplatin as first-line anti-tumor drug.With the development of nanocarrier technology,liposomes have become an ideal carrier for delivering cisplatin drugs due to their excellent properties of targeting,reducing toxicity,and enhancing efficacy.This paper reviews the status of cisplatin liposome both domestically and internationally which have entered clinical trials,including L-NDDP,SPI-077?,Lipoplatin?,LiPlaCis,SLIT and 1LC,etc.Currently,only Lipoplatin? and ILC are showing good potential in cancer therapy.Although cisplatin liposome has made some progress in reducing systemic toxicity and improving treatment efficiency in clinical research,there is still potential for further improvement in tumor targeting and reducing side effects.In the future,more low-toxicity and efficient cisplatin liposomes can be developed through formulation technologies such as co-delivery liposome,stimuli-responsive liposome and targeting liposome.

Objective To explore the application effect of upper abdominal moxibustion combined with bedside ultrasound monitoring of gastric residual volume(GRV)in pre-pyloric feeding in stroke patients.Methods Eighty stroke patients admitted to the Department of Rehabilitation Medicine of Zhejiang Provincial People's Hospital from January 1,to December 31,2023 were selected as the study subjects.They were divided into control group(n=38)and observation group(n=42)using a random number table method.All patients had a nasogastric tube for pre-pyloric feeding.The control group used the traditional syringe aspiration method to monitor GRV,while the observation group used upper abdominal moxibustion combined with bedside ultrasound to monitor GRV.The study compared the differences between two groups in terms of enteral nutrition intolerance,feeding complications,enteral nutrition compliance rate within 7 days of admission,time to achieve enteral nutrition compliance,and changes in hemoglobin(Hb),serum prealbumin,serum albumin(ALB),and serum transferrin before and after 14 days of feeding.Results The incidence rates of vomiting,abdominal distention,intra-abdominal hypertension,reflux,and aspiration pneumonia in observation group were lower than those in control group(P＜0.05).The rate of achieving intestinal nutrition standard within 7 days of hospitalization was significantly higher in observation group compared to the control group.The time to achieve intestinal nutrition standard was shorter in observation group compared to control group.Furthermore,after 14 days of feeding,the levels of Hb and ALB in observation group were higher than those in control group,and the differences were statistically significant(P＜0.05).Conclusion Upper abdominal moxibustion combined with bedside ultrasonic monitoring of GRV can significantly reduce intestinal nutrition intolerance and feeding complications during pre-pyloric feeding in stroke patients,shorten the time to achieve nutritional benchmarks,and improve nutritional status.

Objective:To explore the effect of virtual reality (VR) technology in postoperative pain management for surgical patients.Methods:The literature on VR technology for relieving postoperative pain in surgical patients was electronically retrieved from eight databases, including PubMed, Web of Science and so on. The search period was from database establishment to November 19, 2023. Two researchers independently screened literature, extracted data, and conducted literature quality evaluation, using RevMan 5.4 for Meta-analysis.Results:A total of 18 articles were included. Meta-analysis results showed that VR technology could reduce postoperative resting pain scores [ MD=-1.13, 95% CI (-1.29, -0.96), P<0.001], postoperative 12 hour pain scores [ MD=-0.49, 95% CI (-0.73, -0.24), P<0.001], postoperative 24 hour pain scores [ MD=-0.73, 95% CI (-0.92, -0.54), P<0.001], postoperative 48 hour pain scores [ MD=-0.69, 95% CI (-0.84, -0.53), P<0.001], postoperative 72 hour pain scores [ MD=-0.37, 95% CI (-0.59, -0.16), P<0.001], and postoperative pain scores during dressing changes [ MD=-1.11, 95% CI (-2.06, -0.16), P=0.02], and could improve patient postoperative comfort [ MD=8.31, 95% CI (6.57, 10.06), P<0.001] . Conclusions:As a non-pharmacological intervention, VR technology can alleviate postoperative pain and improve patient comfort in surgical patients. In the future, large-scale and high-quality research is still needed to further verify the effectiveness of VR technology.

Objective:To explore the current situation and influencing factors of amputation decision-making dilemma of diabetic foot patients.Methods:From July to December 2023, 200 patients with diabetic foot in the Tianjin Medical University General Hospital and Tianjin Medical University Chu Hsien-I Memorial Hospital were selected as study subjects by convenience sampling. General Information Questionnaire, Decisional Conflict Scale (DCS), Family APGAR Index, and Hospital Anxiety and Depression Scale were used to conduct a cross-sectional survey. Pearson correlation was used to analyze the correlation between diabetic foot patients' amputation decision-making dilemma and family caring, anxiety and depression, and multiple linear regression was used to analyze the influencing factors of diabetic foot patients' amputation decision-making dilemma.Results:A total of 200 questionnaires were distributed, and 180 valid questionnaires were collected, with a valid response rate of 90.0% (180/200). The DCS score of 180 patients with diabetic foot was (30.04±9.77), 76.7% (138/180) patients scored ≥25.0, and they had decision-making dilemma, and 25.0% (45/180) of patients scored ≥37.5, indicating decision-making delay. Multiple linear regression analysis showed that occupational status, diabetes course, family caring, anxiety and depression were the influencing factors of amputation decision-making dilemma of diabetic foot patients ( P<0.05) . Conclusions:Diabetic foot patients face certain dilemmas in the process of amputation decision-making. Clinical medical and nursing staff should reasonably evaluate the patient's occupational status, disease course, family caring, and psychological state, and develop personalized decision support strategies to improve decision quality and prevent changes in the patient's condition caused by delayed decision-making.

Objective:To investigate the clinicopathological features and molecular characteristics of β-catenin-deficient colorectal cancer.Methods:The clinical, pathological and molecular features of 11 colorectal cancers with β-catenin protein loss diagnosed at the 960th Hospital of People′s Liberation Army of China, from January 2012 to November 2022 were analyzed.Results:Among the 11 patients, 3 were males and 8 were females. Their age ranged from 43 to 74 years, with the median age of 59 years. Six were in the left colon and 5 were in the right colon. One of the 11 cases had lymph node metastasis, 10 cases were well and moderately differentiated adenocarcinoma, and 1 was mucinous adenocarcinoma. Eight cases were of TNM stage T4, 2 of T1 stage and 1 of Tis stage. β-catenin protein was not detected using immunohistochemistry. Sanger sequencing revealed the presence of fragment-deletion mutation in exon 3 of CTNNB1 gene, resulting in loss of β-catenin protein expression.Conclusion:β-catenin deficiency is present in a small number of colorectal cancers and may be associated with exon 3 mutations of CTNNB1 gene.

Objective To explore the effects of comprehensive evaluation and nursing on the rehabilitation and lung function of elderly patients with chronic obstructive pulmonary disease(COPD).Methods A total of 92 elderly COPD patients admitted to Sixth People's Hospital of Nantong from April 2019 to April 2022 were divided into two groups according to the random number table,with 46 patients in each group.The control group adopted routine nursing and the observation group received comprehensive evaluation and nursing.The quality of life,lung function and self-management ability of the two groups were compared.Results There was no significant difference in each parameter between the two groups before the intervention(P＞0.05).After the intervention,the SGRQ,the forced vital capacity(FVC),the ratio of forced expiratory volume in one second to vital capacity(FEV1/FVC),the maximum ventilation volume(MVV)and the diffusion volume of carbon monoxide(DLCO)in the observation group were significantly higher than those in the control group(P＜0.05).The scores of cognitive management(disease knowledge cognition,emotional cognition)and behavioral management(control of inducement,diet,disease monitoring)in the control group were significantly lower than those in the observation group(P＜0.05).Conclusion The comprehensive evaluation and nursing for the elderly COPD patients can effectively improve their quality of life and lung function and enhance their self-management ability.
