Objective:To investigate the current status of malnutrition and its influential factors among patients with stroke and dysphagia, and to develop and validate a malnutrition risk prediction model.Methods:Using a convenience sampling method, 150 patients with stroke and dysphagia admitted to Wenzhou Central Hospital from January 2019 to December 2023 were included in this study. Through a review of the literature and expert consultations, 15 influential factors were identified: age, gender, body mass index (BMI), history of smoking alcohol consumption , number of hospitalizations, education level, Barthel index, history of hypertension, history of diabetes, coronary heart disease, presence of limb disabilities, hemoglobin levels, Glasgow Coma Scale (GCS) score, and National Institutes of Health Stroke Scale score. Patients were categorized into malnutrition and normal groups based on the occurrence of malnutrition. The influential factors for malnutrition were analyzed, and a malnutrition risk prediction model was constructed using regression analysis. The model was presented using a nomogram and subsequently validated.Results:Among the 150 patients with stroke and dysphagia, the average age was (59.34 ± 6.46) years, with 83 females and 67 males. Of these patients, 66 (44.00%) were found to be malnourished. The following factors were identified as independent risk factors for malnutrition in patients with stroke and dysphagia: age (χ2 = 4.03, P = 0.045), BMI ( t = 6.33, P < 0.001), alcohol consumption (χ2 = 3.90, P = 0.048), number of hospitalizations (χ2 = 9.45, P = 0.024), Barthel index (χ2 = 7.78, P = 0.020), presence of limb disabilities (χ2 = 4.64, P = 0.031), hemoglobin levels (χ2 = 4.38, P = 0.036), and GCS score (χ2 = 9.83, P = 0.007) (all P < 0.05). Patients who were older, had a BMI < 18.5 kg/m2, consumed alcohol, had more than five hospitalizations, a Barthel index < 40, limb disabilities, abnormal hemoglobin levels, or a GCS score ≤ 11 were more likely to experience malnutrition (all P < 0.05). The C-index for predicting malnutrition was 0.851, with a 95% CI of (0.809, 0.892). The maximum Youden index was 0.562, with a sensitivity of 84.1% and specificity of 72.1%. Conclusion:The risk factors for malnutrition in patients with stroke and dysphagia include advanced age, alcohol consumption, more than five hospitalizations, limb disabilities, and abnormal hemoglobin levels. Protective factors against malnutrition in these patients are a BMI > 23.9 kg/m2, a Barthel index > 60, and a GCS score ≥ 14. The prediction model demonstrates a significant predictive value for the occurrence of malnutrition in patients with stroke and dysphagia.

This article presents a case of acute ST-segment elevation myocardial infarction (STEMI) in a pregnant woman caused by coronary artery dissection. The 41-year-old patient had undergone cardiac valve surgery at the age of 1 and had no risk factors such as hypertension, diabetes, smoking, alcohol use, or a family history of coronary artery disease. At 31 +1 weeks of gestation, she experienced sudden chest pain for 4 hours and was emergently referred to Peking University First Hospital on June 1, 2021. Electrocardiogram revealed ST-segment elevation in leads I, aVL, and V 2 to V 6. Biochemical assays showed elevated levels of high-sensitivity cardiac troponin I and creatine kinase-MB. Echocardiography indicated segmental ventricular wall motion abnormalities (apical) and reduced left ventricular function, confirming the diagnosis of acute anterior wall STEMI. The patient promptly underwent emergency coronary angiography and percutaneous coronary intervention and confirmed coronary artery dissection. Postoperative care included antiplatelet, anticoagulation, and supportive treatment. At 34 +3 weeks of gestation, with the condition of acute anterior wall STEMI being relatively stable, a cesarean section was successfully performed. Regular cardiology follow-ups were scheduled postpartum, and cardiac function was normal in two years after discharge.

Objective:To explore the clinicopathological characteristics and prognosis of patients with ovarian metastases from colorectal cancer.Methods:A total of 122 female patients with ovarian metastases from colorectal cancer underwent treatment in Cancer Hospital, Chinese Academy of Medical Sciences between 2010 and 2015 were recruited. The clinicopathological features, treatment details and survival data of these patients were retrospectively analyzed. Kaplan-Maier method was used for survival analysis, log rank test and Cox proportional hazards model were used for prognostic factor analysis.Results:The median overall survival (OS) was 19.7 months. The 1-year, 3-years and 5-years OS rates were 72.1%, 24.7% and 9.9%, respectively. A total of 99 (81.1%) patients underwent oophorectomy. The median OS of patients who underwent oophorectomy was 21.9 months, significantly longer than 10.3 months of patients without oophorectomy ( P<0.01). Ovary as the only site of metastasis, primary tumor resection, and oophorectomy were associated with improved survival (all P<0.01). Primary tumor resection and oophorectomy were independent prognostic factors for OS (both P<0.01). Conclusion:Patients with ovarian metastases from colorectal cancer might acquire a survival benefit from surgical resection of the primary tumor and ovaries.

Objective: To investigate the changes of coagulation indexes in normal pregnant women in early and late pregnancy. Methods: The coagulation indexes in early and late pregnancy including activated partial thromboplastin time (APTT), APTT ratio, prothrombin time (PT), PT ratio, prothrombin activity, international normalized ratio, fibrinogen (Fib) and thrombin time (TT) were retrospectively collected from 196 normal pregnant women delivered in Peking University First Hospital from August 2013 to September 2014. Differences in these indexes before and after the seventh gestational week of early pregnancy and in early and late pregnancy were compared. In addition, the normal reference values were calculated. Paired t test and sum-rank test were used for statistical analysis. The reference values were presented with P_2.5-P_97.5. Results: In early pregnancy, some coagulation indexes after the seventh weeks were shorter than those before, such as APTT [30.3 (26.1-35.5) vs 32.1 (27.9-36.8) s, Z=25.850, P<0.001] and TT [13.8 (12.2-16.0) vs 14.5 (12.3-16.4) s, Z=16.720, P<0.001], but Fib [3.3 (2.5-4.3) vs 2.9 (2.2-3.8) g/L, Z=43.180, P<0.001] became higher. APTT [(27.5±1.6) vs (31.4±2.4) s, t=24.736, P<0.001], PT [(9.7±0.5) vs (11.0±0.8) s, t=18.647, P<0.001] and TT [(13.3±0.8) vs (14.2±1.0) s, t=9.255, P<0.001] were significantly shorter, while Fib [(4.4±0.5) vs (3.1±0.4) g/L, t=-29.152, P<0.001] was higher in late pregnancy than in early pregnancy. The reference values of APTT, PT, Fib and TT in early pregnancy were 26.5-36.0 s, 9.4-12.4 s, 2.4-4.0 g/L and 12.3-16.4 s, and those in late pregnancy were 25.0-31.2 s, 8.8-10.6 s, 3.4-5.4 g/L and 12.0-14.9 s, respectively. Conclusions The coagulation indexes of pregnant women change significantly since the beginning of early pregnancy. APTT, PT and TT are shorter, while Fib is higher in late pregnancy than in early pregnancy.

?? [Abstract]? Objective? To investigate the current status of nursing care for patients with Alzheimer's disease(AD) in China in order to explore the reform of its care model. Methods? From January to April 2018, 12 medical staff, 19 patients with AD and their families from the Departments of Geriatrics and Neurology in a ClassⅢ Grade A hospital in Chengdu, psychiatric hospitals and community health service centers were selected as the research objects by purposive sampling. Semi-structured interviews were conducted, the data obtained was analyzed by Colaizzi phenomenological analysis method. Results? The results of the interview were divided into three themes: medical care, hierarchical care elements, and the needs of patients and their families. Medical and nursing services in different levels of medical institutions have different emphasis; patients' care needs vary in different periods of illness; care elements cover biological, psychological and social dimensions. Conclusions? Attention should be paid to early screening of AD diseases, early intervention in cognitive rehabilitation training, evidence-based construction of acute-medium-long-term care system for AD, and development of long-term care insurance for AD to serve patients accurately.

OBJECTIVETo observe and study the effects of sivelestat on acute lung injury in dogs with severe burn-blast combined injury.

METHODSThirty-two male beagle dogs of clean grade were divided into 4 groups: uninjured group (U), combined injury control group (CIC), combined injury+low dose of sivelestat group (CI+LS), combined injury+high dose of sivelestat group (CI+HS), with 8 dogs in each group. Except for the dogs in group U which were not injured, the dogs in the other 3 groups were inflicted with severe burn-blast combined injury. According to the Parkland formula, the dogs in groups U and CIC were infused with physiological saline, and the dogs in groups CI+LS and CI+HS received sivelestat with the dosage of 0.5 and 2.0 mg·kg(-1)·h(-1) respectively in addition. The 24 h continuous intravenous infusion was carried out for 2 days. At post injury hour (PIH) 6, CT scanning was conducted to observe the lung damage. At PIH 2, 6, 12, 24, and 48, mean arterial pressure (MAP), respiratory rate (RR), extra vascular lung water (EVLW), pulmonary vascular permeability index (PVPI), PaO2, and PaCO2 were measured; the contents of neutrophil elastase (NE), IL-8, and TNF-α were determined by ELISA. At PIH 48, all the dogs were sacrificed, and the lung tissues were harvested to measure the wet to dry lung weight ratio. The same examination was carried out in the dogs of the group U at the same time points. Data were processed with analysis of variance of repeated measurement and LSD test.

RESULTS(1) CT images showed some exudative lesions in the dogs of groups CIC and CI+LS but not in the dogs of groups U and CI+HS. (2) No statistically significant differences were observed in MAP at each time point between every two groups (with P values above 0.05). The RR values in group U were significantly different from those of the other 3 groups at all time points (with P values below 0.05). The values of EVLW and PVPI in 3 combined injury groups were significantly different from those in group U at PIH 6, 12, 24, and 48 (with P values below 0.05). The values of RR and EVLW in group CI+LS were significantly different from those in group CI+HS at PIH 12, 24, and 48 (with P values below 0.05). The values of PVPI in group CI+LS were significantly different from those in group CI+HS at PIH 24 and 48 (with P values below 0.05). (3) The levels of PaO2 and PaCO2 showed significant differences between group U and the other 3 groups at each time point (with P values below 0.05). The levels of PaO2 in group CI+LS were significantly different from those in CI+HS group at PIH 12, 24, and 48 (with P values below 0.05). The level of PaCO2 showed significant differences between group CI+LS and group CI+HS at PIH 24 and 48 (with P values below 0.05). (4) The contents of NE (except for PIH 2), TNF-α, and IL-8 showed significant differences between group U and the other 3 groups at each time point (P < 0.05 or P < 0.01). At PIH 2, 6, 12, 24, and 48, the contents of NE in groups U, CIC, CI+LS, and CI+HS were respectively (69 ± 21), (83 ± 24), (80 ± 20), (75 ± 17), (72 ± 27) pg/mL; (66 ± 24), (196 ± 20), (231 ± 26), (252 ± 25), (266 ± 22) pg/mL ; (71 ± 22), (180 ± 27), (214 ± 21), (194 ± 24), (218 ± 20) pg/mL; (68 ± 22), (136 ± 24), (153 ± 22), (146 ± 26), (150 ± 28) pg/mL. NE values in group CI+HS were statistically different from those in groups CIC and CI+LS at PIH 6, 12, 24, and 48 (with P values below 0.05). The contents of TNF-α in group CI+LS were statistically different from those in groups CIC and CI+HS at PIH 24 and 48 (with P values below 0.05). The contents of IL-8 in group CI+LS were statistically different from those in group CI+HS at PIH 24 and 48 (with P values below 0.05). (5) At PIH 48, the wet to dry lung weight ratio of group CIC was statistically different from that in group CI+LS or group CI+HS (with P values below 0.05); there was also difference between group CI+LS and group CI+HS (P < 0.05).

CONCLUSIONSSivelestat, especially in a high dose, exerts a protective effect in acute lung injury after burn-blast combined injury through improving the index of blood gas analysis, ameliorating pulmonary edema, and lowering the production of pro-inflammatory mediators.

Objective To investigate the effects of gestational diabetes mellitus (GDM) on the growth rate of fetuses.Methods This was a retrospective study.Women who had deliveries in Peking University First Hospital between January 2012 and June 2013 were enrolled.Matched by maternal age,they were divided into four groups with 100 cases in each group:macrosomic fetuses of mothers with GDM (GDM-macrosomia group),normal birth weight infants of mothers with GDM (GDM-non-macrosomia group),macrosomic fetuses of mothers with normal pregnancy (normal-macrosomia group),and normal birth weight infants of mothers with normal pregnancy (normal-non-macrosomia group).The fetal abdominal circumference was measured at 20+1-24,28+1-32,32+1-37 weeks and 37+1 weeks to delivery under prenatal ultrasound.The growth rate of fetal abdominal circumference was calculated (abdominal circumference/gestational weeks).The analysis of variance,the least significant difference-t test and Student's t test were used for statistical analysis.Results At early pregnancy [(9.2±2.6) weeks of gestation] and 20+1-24,28+1-32,32+1-37 weeks and 37+1 weeks to delivery,the weight and body mass index (BMI) of the mothers in GDM-macrosomia group were higher than those in the other three groups (all P＜0.05).The body weight of the mothers increased by (15.5±5.4),(13.5±3.6),(16.4±4.1) and (16.2±4.3) kg,respectively,compared with early pregnancy.At 20+1-24,28+1-32,32+1-37 weeks and 37+1 weeks to delivery,the fetal abdominal circumference of GDM-macrosomia group was (182.0± 13.9),(270.7± 17.7),(335.2±21.3) and (362.3± 18.7) mm,respectively,being higher than that in GDM-non-macrosomia group [(176.8± 13.0),(256.6± 13.5),(313.2± 17.5) and (335.8± 15.5) mm] and normal-nonmacrosomia group [(176.9± 11.8),(260.0± 14.2),(310.6± 21.4) and (334.5 ± 16.1) mm] (all P＜0.05).The fetal abdominal circumference of GDM-macrosomia group was even higher than normal-macrosomia group at 32+1-37 weeks [(335.2±21.3) vs (326.1 ± 19.1) mm,t=4.01,P＜0.05].The changes of the growth rate of fetal abdominal circumference were consistent with the fetal abdominal circumference.Conclusions GDM accelerates fetal growth.

OBJECTIVEThe aim of this study was to assess the feasibility and safety of laparoscopic nerve plane-sparing radical hysterectomy (NPSRH) and compare with that of open NPSRH.

METHODSOne hundred and thirty-four patients with FIGO stage Ib1-IIa2 cervical cancer were enrolled in the study. Thirty-three patients underwent laparoscopic NPSRH. During the operation, the pelvic autonomic nerve plane which is directly underneath the ureter was integrally preserved by dissecting the pelvic spaces laparoscopically. The vessels around the nerve plane were controlled by Hem-o-lok polymer clips. One hundred and one patients underwent open NPSRH without special instruments. The clinical, pathological and surgery-related parameters were compared between the two groups. Moreover, postoperative short-term bladder function of these patients was also analyzed.

RESULTSThere was no significant difference between the laparoscopic group and open group in terms of age, body mass index, previous surgery, FIGO stage, pathologic type, etc. (P > 0.05). The mean duration of surgery in the laparoscopic group was significantly longer [(303.8 ± 67.5) min vs. (272.4 ± 57.5) min] (P < 0.01). But, the laparoscopic group had less blood loss [177.0 ml vs. 474.5 ml, P < 0.01] and blood transfusion rate [ 6.1% (2/33 cases) vs. 49.5% (50/101 cases), P < 0.001]. There was no significant difference regarding the proportion of patients who firstly passed the post-void residual urine volume (PVR) test (P > 0.05). The median time of catheterization between the two groups were also comparable (P > 0.05). However, the postoperative hospital stay was significantly shorter in the laparoscopic group [median postoperative hospital stay 9.2 days vs. 11.0 days, P < 0.001].

CONCLUSIONSLaparoscopic NPSRH is feasible. It seems to be comparable with open NPSRH in terms of preserving pelvic nerve function, but is more favorable in terms of blood loss and postoperative recovery.
