Objective:To analyze the risk factors for aspiration pneumonia (AP) among stroke survivors with dysphagia and construct a prediction model.Methods:The records of one hundred and forty-eight stroke survivors with dysphagia admitted since 2021 were retrospectively analyzed. They were divided into an AP group ( n=46) and a non-AP group ( n=102). Univariate and multivariate logistic regressions were evaluated seeking independent risk factors for AP. the receiver-operating characteristic (ROC) curves were used to analyze predictive power. Results:The incidence of AP was 31%. Multivariate logistic regression analysis showed that age, Barthel index, Kubota′s water drinking test grading, nutritional support methods and the neutrophil/lymphocyte ratio (NLR) could be useful independent predictors of AP. The areas under the ROC curves suggested that Kubota grading, nutritional support methods, the NLR and the Barthel index could be used to prepare a prediction nomogram with good sensitivity and specificity.Conclusions:Age, Barthel index, Kubota water drinking test grades, nutritional support methods and NLR are independent predictors of AP for stroke survivors with dysphagia. Combining them in a nomogram gives better predictive power than using the factors alone.

Objective To summarize the experience of integrative palliative care at Peking Union Medi-cal College Hospital and provide a reference for promoting the integrative palliative care model.Methods Twenty cases receiving integrative palliative care at Peking Union Medical College Hospital were collected.The clinical characteristics,reasons for initiating integrative palliative care,the process of integrative palliative care,and feedback from these cases were summarized.Results Insomnia(11 cases,55％)and pain(9 cases,45％)were the most common symptoms requiring control in the 20 cases.The integrative palliative care team assisted in medical decision-making for 17 cases(85％),prepared end-of-life for 9 cases(45％),assisted in the transfer for 3 cases(15％),and provided comfort care for all the 20 cases(100％).Conclusions The integrative palliative care model can help alleviate suffering in end-of-life patients and provide support to patients'families and the original medical teams.This model is worth further promotion within class A tertiary hospitals.

OBJECTIVE To study the effects of Zigui yichong formula on premature ovarian insufficiency （POI） in mice through glycolysis metabolic pathway. METHODS Eighty SPF C57BL/6N female mice were divided into normal group， model group， Zigui yichong formula group （14.175 g/kg）， Zigui yichong formula+2-deoxy-D-arabino-hexose （2-DG） group （Zigui yichong formula 14.175 g/kg + glycolysis inhibitor 2-DG 100 mg/kg）， with 20 mice in each group. Except for the normal group， POI model mice were induced by intraperitoneal administration of cyclophosphamide in the other groups. After the model was successfully established， each group was given corresponding drugs. HE staining was employed to observe the pathomorphological changes in ovarian tissue and to count follicles at all developmental stages； radioimmunoassay was conducted to measure the serum levels of estradiol （E2）， anti-Müllerian hormone （AMH）， and follicle-stimulating hormone （FSH）； TUNEL assay was employed to detect apoptosis in ovarian granulosa cells of mice； the activities of hexokinase （HK）， pyruvate kinase （PK） and lactate dehydrogenase （LDH） were detected by colorimetry； Western blot and real-time fluorescence quantitative PCR were employed to analyze the protein and mRNA expressions of B-cell lymphoma-2 （Bcl-2）， Bcl-2 associated X protein （Bax）， caspase-3， HK2， pyruvate kinase M2 （PKM2）， and lactate dehydrogenase A （LDHA）. RESULTS Compared with model group， the number of primordial follicles， growing follicles， antral follicles and granulosa cells were increased significantly（P＜0.05）， and granulosa cells arranged neatly， but the number of atretic follicles and granulosa cells apoptosis were decreased significantly in Zigui yichong formula group （P＜0.05）； the serum levels of E2 and AMH， the activities of HK， PK and LDH， protein and mRNA expressions of Bcl-2， HK2， PKM2 and LDHA were increased significantly （P＜0.05）； the serum levels of FSH， the protein and mRNA expressions of Bax and caspase-3， Bax/Bcl-2 ratio were decreased significantly （P＜0.05）. 2-DG could reverse the improvement effects of Zigui yichong formula on the above indexes of POI model mice. CONCLUSIONS Zigui yichong formula may inhibit the apoptosis of ovarian granulosa cells， reduce follicle atresia and improve ovarian reserve function by promoting glycolysis levels in POI model mice.

Entinostat plus exemestane in hormone receptor-positive (HR+) advanced breast cancer (ABC) previously showed encouraging outcomes. This multicenter phase 3 trial evaluated the efficacy and safety of entinostat plus exemestane in Chinese patients with HR + ABC that relapsed/progressed after ≥1 endocrine therapy. Patients were randomized (2:1) to oral exemestane 25 mg/day plus entinostat (n = 235) or placebo (n = 119) 5 mg/week in 28-day cycles. The primary endpoint was the independent radiographic committee (IRC)-assessed progression-free survival (PFS). The median age was 52 (range, 28-75) years and 222 (62.7%) patients were postmenopausal. CDK4/6 inhibitors and fulvestrant were previously used in 23 (6.5%) and 92 (26.0%) patients, respectively. The baseline characteristics were comparable between the entinostat and placebo groups. The median PFS was 6.32 (95% CI, 5.30-9.11) and 3.72 (95% CI, 1.91-5.49) months in the entinostat and placebo groups (HR, 0.76; 95% CI, 0.58-0.98; P = 0.046), respectively. Grade ≥3 adverse events (AEs) occurred in 154 (65.5%) patients in the entinostat group versus 23 (19.3%) in the placebo group, and the most common grade ≥3 treatment-related AEs were neutropenia [103 (43.8%)], thrombocytopenia [20 (8.5%)], and leucopenia [15 (6.4%)]. Entinostat plus exemestane significantly improved PFS compared with exemestane, with generally manageable toxicities in HR + ABC (ClinicalTrials.gov #NCT03538171).

Objective:To analyze the genetic etiology and prognosis in fetuses with increased nuchal translucency (NT) in order to assist in the clinical prenatal genetic counseling and diagnosis.Methods:This study retrospectively enrolled 1 658 cases of singleton pregnancy (<35 years old) receiving invasive prenatal diagnosis, including karyotype analysis and/or chromosome microarray analysis or copy number variation (CNV) sequencing, due to NT value ≥2.5 mm in the first trimester in Henan Provincial People's Hospital from August 2014 to December 2021. They were divided into different groups according to the thickness of NT (≥2.5-<3.0, ≥3.0-<3.5, ≥3.5-<4.5, ≥4.5-<5.5, ≥5.5-<6.5 and ≥6.5 mm groups) and abnormal ultrasound findings (isolated increased NT group, increased NT complicated by soft markers/non-severe structural abnormality group and increased NT complicated by severe structural abnormality group). The results of invasive prenatal diagnosis and pregnancy outcomes were compared between different groups using Chi-square test and trend Chi-square test. Results:The detection rates of numerical abnormalities of chromosomes were 15.8% (262/1 658) and 17.6% (252/1 431) when the NT thickness cut-off value were 2.5 mm or 3.0 mm, respectively. Overall, the detection rate of numerical abnormalities of chromosomes increased with thickness of NT ( χ2trend=180.75, P<0.001), ranging from 6.6% (44/671) in the NT≥2.5-<3.5 mm group to 45.6% (113/248) in the NT≥5.5 mm group. The incidence of pathogenic/likely pathogenic CNV(P/LP CNV) did not increased with NT thickness ( χ2trend=3.26, P=0.071), and the highest detection rate was observed in the NT≥4.5-<5.5 mm group (9.0%, 19/211). The detection rate of numerical abnormalities of chromosomes plus P/LP CNV in the isolated NT≥2.5-<3.0 mm group and NT≥3.0-<3.5 mm group were 5.3% (10/188) and 9.6% (36/375), respectively, however, the difference was not statistically significant ( χ2=3.06, P=0.080). The detection rates of numerical abnormalities of chromosomes plus P/LP CNV in the isolated NT≥3.5-<4.5 mm group and NT≥2.5-<3.0 mm complicated by soft markers/ non-severe structural abnormality group were 12.7% (52/410) and 24.1% (7/29), respectively, and the risk were 2.6 times (95% CI: 1.3-5.2) and 5.7 times (95% CI: 2.0-16.4) of the isolated NT≥2.5-<3.0 mm group, respectively. The pregnancy termination rate increased with the NT thickness ( χ2trend=304.42, P<0.001), ranging from 10.8% (23/212) in the NT≥2.5-<3.0 mm group to 90.7% (117/129) in the NT≥6.5 mm group. After exclusion of the pregnancies terminated due to numerical abnormalities of chromosomes and P/LP CNV, 87.6% (862/984) of the fetus with increased NT were born alive. Conclusions:The detection rate of numerical abnormalities of chromosomes increases with the thickness of NT. Invasive prenatal diagnosis is required for non-advance aged singleton pregnant women when fetuses present with isolated NT≥2.5 mm with or without soft markers/structural abnormalities.

The view of life in Huang Di Nei Jing discusses the essence of human life by exploring the origin, structure and existence of human life, elucidates the overall quality of human life by observing the state and length of human life, and summarizes the characteristics of human life by analyzing the commonalities and unique characteristics of human life with other lives. On the one hand, this life view respects the objectivity and regularity of life, and enabling people to calmly face death but actively seeking higher possibilities of life, which reflects the reasonable self-awareness of ancient doctors towards human life. On the other hand, it affirms the intrinsic value of life, advocates meeting the subjective value of life and pursuing the external value of life, and expresses the self-pursuit of exploring the existence value of human life, which makes the life view in Huang Di Nei Jing quite humanistic. This humanistic life view has important reference significance for modern medical practice. Reasonable absorbing the humanistic spirit of the life view in Huang Di Nei Jing is conducive to the return of modern medicine to the medical essence of saving the dying and healing the wounded, as well as the establishment of the medical value of people-oriented.

Objective:To evaluate the efficacy and safety of allopurinol in the treatment of chronic kidney disease.Methods:The databases of Embase, PubMed and the Cochrane library were searched for randomized controlled trials of allopurinol in patients with chronic kidney disease. According to the Cochrane system evaluation method, two evaluators independently screened the literature and extracted the data, and analyzed the results with Revman 5.3 software.Results:Finally, 10 articles were included, including 940 patients (472 in the experimental group and 468 in the control group). Meta analysis showed that allopurinol treatment could reduce blood uric acid ( MD=-2.40, 95% CI: -2.74--2.05, P<0.01), 24-hour urinary protein ( MD=-0.61, 95% CI: -1.17--0.06, P=0.03) and increase estimation of glomerular filtration rate(eGFR) ( MD=2.51, 95% CI: 1.86-3.17, P<0.01). There was no significant difference in adverse events between the experimental group and the control group ( OR=1.40, 95% CI: 0.61-3.19, P=0.42), but allopurinol treatment could reduce the risk of cardiovascular events ( OR=0.58, 95% CI: 0.38-0.89, P=0.01). Conclusions:Allopurinol treatment of chronic kidney disease can reduce urinary protein, improve eGFR, and reduce the risk of cardiovascular events.
