Objective To assess the effect of early nutritional intervention on the patients with respiratory diseases at nutritional risk. Methods A total of 130 patients with respiratory disease who were hospitalized in Shanghai Fifth People’s Hospital, Fudan University between May 2023 and December 2024 and had a nutritional risk screening 2002 score ≥3 points. Based on the initiation time of nutritional intervention, patients were divided into an early group (≤5 days, n＝65) and a late group (＞5 days, n＝65). Results In the early group, prealbumin (P-ALB) and retinol-binding protein (RBP) levels were significantly higher (P＜0.01), C-reactive protein (CRP), procalcitonin (PCT) levels were significantly lower after intervention (P＜0.05). Compared with the late group, the hospital costs were lower and hospital stays were shorter in the early group (P＜0.001). Spearman analysis showed ALB, P-ALB, and total protein (TP) were negatively correlated with hospital costs (r＝－0.37, －0.20, and－0.22, P＜0.05). RBP, ALB, P-ALB, and lymphocyte count (LYM) were negatively correlated with CRP (r＝－0.30, －0.26, －0.37, －0.18, P＜0.01), RBP, ALB, P-ALB, hemoglobin (HB), and TP were negatively correlated with PCT (r＝－0.23,－0.36, －0.40, －0.30, －0.19, P＜0.05). Conclusions For patients with respiratory diseases, early nutritional assessment should be underwent, and for patients with nutritional risk screening 2002 score ≥3 points, early nutritional intervention could improve the nutritional status and alleviate inflammatory response, promote recovery, shorten the hospital stays.

ObjectiveTo investigate the mechanism of modified Shenhong Tongluo prescription on cell apoptosis in rats with myocardial ischemia-reperfusion injury （MIRI）. MethodSixty Sprague-Dawley （SD） rats were randomly divided into a blank group， a model group， low-， medium-， and high-dose groups of modified Shenhong Tongluo prescription， and a simvastatin group. Except for the blank group， a rat model of MIRI was prepared by ligating the left anterior descending coronary artery. Starting from the first day after successful modeling， the blank group （1.0 mL·kg^-1 physiological saline）， model group （1.0 mL·kg^-1 physiological saline）， low-， medium-， and high-dose groups of modified Shenhong Tongluo prescription （1.031， 2.063， and 4.126 g·kg^-1 Shenhong Tongluo prescriptiona standard concentrate）， and simvastatin group （0.71 mg·kg^-1 simvastatin） were orally administered once daily for 2 weeks. Hematoxylin-eosin （HE） staining was used to observe the pathological changes of cardiomyocytes. Enzyme-linked immunosorbent assay （ELISA） was used to detect the levels of serum creatine kinase isoenzyme （CK-MB）， interleukin-6 （IL-6）， and tumor necrosis factor-α （TNF-α）. TdT-mediated dUTP nick-end labeling（TUNEL） staining was used to detect the apoptosis rate of rat cardiomyocytes. Western blot was used to detect the expression levels of apoptosis-related proteins B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， and caspase-3. ResultCompared with the blank group， in the model group， HE staining showed disturbed arrangement of cardiomyocytes， incomplete fibers， focal necrosis of cardiomyocytes， and inflammatory cell infiltration； serum CK-MB， IL-6， and TNF-α levels were significantly increased （P<0.05）； apoptosis rate of cardiomyocytes was significantly increased （P<0.01）， with significantly increased expression levels of Bax and Caspase-3 proteins， and significantly decreased Bcl-2 expression （P<0.05）. Compared with the model group， the low-， medium-， and high-dose groups of modified Shenhong Tongluo prescription significantly reduced CK-MB， IL-6， and TNF-α levels （P<0.05）， significantly downregulated cardiomyocyte apoptosis rate （P<0.05）， significantly decreased Bax and Caspase-3 proteins， and significantly increased Bcl-2 expression levels （P<0.01）. In the modified Shenhong Tongluo prescription groups， the expression levels of Bax and Caspase-3 proteins significantly decreased with increasing dosage， while the expression level of Bcl-2 significantly increased with increasing dosage of modified Shenhong Tongluo prescription （P<0.05）. ConclusionShenhong Tongluo prescription can alleviate myocardial tissue pathological damage and reduce myocardial cell apoptosis， possibly by inhibiting Caspase-3 and Bax expression and promoting Bcl-2 expression.

surgery.Methods Eighty-four patients who underwent OLV during thoracoscopic lobectomy at the Affiliated Suzhou Hospital of Nanjing Medical University from January 2021 to April 2022 were selected as research subjects,and the patients were divided into the observation group and control group by using a random number table,with 42 patients in each group.Patients in the observation group received ultrasound-guided SGB before anesthesia induction,while patients in the control group did not undergo puncture procedures.Patients in both groups received the same anesthesia induction and maintenance protocols.Hemodynamic,respiratory and arterial blood gas parameters were recorded at various time points:upon entering the operating room(T0),before OLV(T1),30 minutes after OLV initiation(T2),60 minutes after OLV initiation(T3),completion of surgery(T4),and 30 minutes after extubation(T5).Oxygenation index(OI),intrapulmonary shunt rate(Qs/Qt)and pH values of patients in the two groups were compared at these time points.Venous blood were collected from patients in both groups at T0,T3 and T5,and enzyme-linked immunosorbent assay was employed to measure the levels of surfactant protein-A(SP-A),superoxide dismutase(SOD),malondialdehyde(MDA),interleukin-6(IL-6)and interleukin-10(IL-10).Postoperative SGB-related complications and pulmonary complications within 72 hours were

significant difference compared to that at T0(P＞0.05);serum MDA level in the observation group was significantly lower than that in the control group(P＜0.05).At T3 and T5,serum SOD level in the control group was significantly lower than that at T0,while serum SOD level in the observation group was significantly higher than that at T0(P＜0.05);serum SOD level in the observation group was significantly higher than that in the control group(P＜0.05).Four patients in the observation group experienced symptoms of unilateral recurrent laryngeal nerve block,and one patient experienced brachial plexus nerve block,but all improved within 24 hours after surgery.No other adverse reactions were observed during follow-up.Within 72 hours postoperatively,one patient in the control group experienced hypoxemia.Conclusion Preoperative ultrasound-guided SGB has lung-protective effects on patients undergoing OLV in thoracoscopic surgery,which significantly improves OI,reduces intrapulmonary shunts,and inhibits inflammatory response and oxidative stress.

Objective:To explore the impact of treatment duration with human urinary kallidinogenase (HUK) on the efficacy and safety of acute ischemic stroke (AIS).Methods:In this subgroup analysis of RESK study, a total of 990 AIS patients recruited from 65 centers in China between August 2015 and June 2020 were included and divided into short medication group (HUK for 8 days, n=185) or long medication group (HUK for 15 days or 21 days, n=805). The proportions of patients with modified Rankin Scale (mRS) score of 0, 0-1, 0-2 at 90 days, National Institutes of Health Stroke Scale (NIHSS) score change from baseline to 22 days, the proportions of patients with Barthel index (BI)≥95 at 90 days, and the incidences of adverse events were analyzed. Comparisons between groups were conducted using chi-square test, single factor and multivariate Logistic regression analysis, etc. Results:Multivariate regression analysis showed that the proportions of patients with 90-day mRS score of 0-2 [74.1% (137/185) vs 75.0% (604/805); OR=1.047, 95% CI 0.676-1.620, P=0.838] and 22-day NIHSS score change from baseline (4.60±2.00 vs 4.26±2.80; OR=-0.390, 95% CI -1.125-0.344, P=0.297) showed no statistically significant difference between the short medication and long medication groups; the proportions of patients with 90-day mRS score of 0-1 [48.1% (89/185) vs 59.1% (476/805); OR=0.674, 95%CI 0.463-0.983, P=0.041] and 90-day BI≥95 [43.6% (79/181) vs 55.1% (442/802); OR=0.614, 95%CI 0.420-0.897, P=0.012] were significantly lower in the short medication group than in the long medication group. There was no statistically significant difference in the incidences of adverse events between these 2 groups. Conclusions:In AIS patients, consecutive 8-day dosing of HUK improved immediate (22-day NIHSS score) and long-term outcome (90-day mRS score 0-2) and was safely tolerated. When applicable, extended duration of HUK could improve long-term disability-free rate (90-day mRS score 0-1) and quality of life (90-day BI) without increasing the risk of adverse events.

Objective:To investigate the effectiveness and safety of ultrasound-guided endovascular therapy for autogenous arteriovenous fistula (AVF) thrombosis.Methods:It was a single-center retrospective cohort study. Data of patients undergoing ultrasound-guided intravascular therapy due to AVF thrombosis in the First Hospital of Hebei Medical University from August 2018 to June 2021 were analyzed. According to different surgical procedures, the patients were divided into two groups. Patients treated with percutaneous transluminal angioplasty (PTA) + drilling thrombectomy were in group A, and patients treated with PTA only were in group B. After 1 year of follow-up, the surgical technique success rate, primary patency rate, secondary patency rate and complications were compared between the two groups.Results:A total of 152 patients were enrolled, including 74 in group A and 78 in group B. There were no significant differences in gender, age, proportion of patients with diabetes and hypertension, and thrombosis time of AVF between the two groups (all P>0.05). Compared with group B, the diameter and length of thrombus in group A were larger [13.0(9.0, 16.0) mm vs. 6.0(5.0, 6.5) mm, Z=-9.362, P<0.001; 12(8, 15) cm vs. 3(3, 4) cm, Z=-10.061, P<0.001], and the establishment time of AVF was longer [5(2, 7) years vs. 2(1, 5) years, Z=-2.698, P=0.007]. Among the overall patients, the success rate of surgery was 96.7% (147/152), and the success rate of surgery was 95.9% (71/74) in group A and 97.4% (76/78) in group B respectively, with no statistical difference ( χ2=0.004, P=0.952). Kaplan-Meier survival analysis showed that, overall, the primary patency rate at 3rd, 6th and 12th month after operation was 87.1%, 71.4% and 56.6%, and the secondary patency rate was 97.1%, 96.4% and 94.1%, respectively. The primary patency rate of group A at 3rd, 6th and 12th month was 82.4%, 66.7% and 53.6%, and the secondary patency rate was 95.7%, 94.2% and 89.7%, respectively. The primary patency rate of group B at 3rd, 6th and 12th month was 91.5%, 73.2% and 59.7%, and the secondary patency rate was 98.6%, 98.6% and 98.5%, respectively. There was no significant difference in the primary and secondary patency rate between group A and group B at 3rd, 6th and 12th month (all P>0.05). The duration of operation in group A was longer than that in group B [2.0(1.9, 2.0) h vs. 2.0(1.0, 2.0) h, Z=-5.181, P<0.001], but no serious complications occurred in both groups. Conclusion:The two surgical methods are effective, safe and reliable in the treatment of AVF thrombosis, and have high clinical application value.

MethodsEighty patients with IFP in the acute stage were randomly divided into 40 cases each in the treatment group and the control group. In the control group， oral prednisone acetate tablets were administered during the acute stage when the disease duration was less than 10 days； and electroacupuncture and flash cupping were provided during the recovery stage when the disease duration was more than 10 days， five times a week. For treatment group in acute stage， the stellate ganglion， vagus nerve stimulation point in the auricular cavity， Yifeng （TE 17） and Tinghui （GB 2） were needled on the affected side on the basis of the treatment of control group， with Yifeng and Tinghui connecting to electroacupuncture apparatus， once a day； point bloodletting and then cupping in Yifeng 2 times a week； in recovery stage， the treatment was the same as that of the control group. Both groups were treated until the 45th day from onset. The primary outcome was the Toronto facial grading system （SFGS）， and the secondary outcomes included house-brackmann （H-B） grade， facial disability index （FDI） score， and number of H-B grade-Ⅰ cases. Adverse events were recorded in both groups. ResultsThe SFGS scores of the patients in both groups were higher on the 10th， 30th and 45th days after onset of disease compared with those before the treatment （P＜0.05）； the H-B grade was lower on the 30th and 45th days after the onset of the disease compared with those before the treatment （P＜0.05）； and the facial disability index physical function （FDIP） and facial disability index social function （FDIS） scores were higher on the 30th and 45th days after onset of disease （P＜0.05）. SFGS scores of patients in the treatment group were significantly higher than those of the control group on the 30th and 45th days after onset （P＜0.05）； H-B grade was significantly lower than that of the control group on the 30th and 45th days after onset （P＜0.05）； and FDIP scores on the 45th day after onset， and FDIS scores on the 30th and 45th days after onset were significantly higher than those of the control group （P＜0.05）. At the end of treatment， 77.50% （31 cases） achieved H-B grade-Ⅰ in the treatment group， which was more than 55.00% （22 cases） in the control group （P＜0.05）. No adverse events occurred in either group. ConclusionElectroacupuncture combined with point bloodletting and cupping for IFP in acute stage can improve the recovery degree of facial nerve function， improve effectiveness， and show a high degree of safety.

Objective: To evaluate the safety of free bivalent human papilloma virus (HPV) vaccine for junior middle school girls in Jiangxi Province, so as to provide the reference for HPV vaccination. Methods: The number of free inoculation of bivalent HPV vaccine for junior middle school girls in Jiangxi Province from August 1, 2023 to May 31, 2024 were collected by Jiangxi Provincial Immunization Planning Information System, and the cases of adverse events following immunization (AEFI) were collected by China Disease Prevention and Control Information System. A descriptive analysis was conducted to assess the incidence of AEFI among middle school girls who received free bivalent HPV vaccine. Results: Junior middle school girls in Jiangxi Province were vaccinated with free bivalent HPV vaccine for 1 061 023 doses, and 67 cases of AEFI were reported. Among the 67 cases, there were 50 cases of general reaction, 7 cases of abnormal reaction, 8 cases of psychogenic reaction and 2 cases of coupling syndrome. The reported incidence of AEFI, adverse reactions and psychogenic reactions were 6.31/100 000, 5.37/100 000 and 0.75/100 000 respectively. Adverse reactions were primarily general reactions (87.72%), with abnormal reactions counting for 12.28%. All AEFI cases were cured or improved, and no death or disability cases were reported. Conclusion The free vaccination of bivalent HPV for junior high school girls in Jiangxi Province is identified as highly safe, low adverse reaction reporting rate, and mainly general reactions, but attention should be paid to the prevention of psychogenic reactions in adolescents.

【Objective】 To investigate the development of adaptability in children aged 2 - 6, and to explore its influencing factors, so as to provide reference for promoting the development of adaptability in young children. 【Methods】 Data were from the National Nutrition and Health Systematic Survey for Children in China, and 3 319 children aged 2 - 6 and their parents from 28 sites across 14 provinces were recruited in this study.The Development Scale for Children Aged 0 - 6 years (WS/T 580-2017) was used to measure the developmental quotient of children′s adaptive ability, and a survey questionnaire was used to collect relevant information about children and their parents. 【Results】 Among 3 319 children aged 2 - 6, the proportion of slightly low or low level of adaptability, moderate adaptability development, good and excellent adaptability development was 7.68%,66.25% and 26.06%, respectively.The proportion of children aged 5 - 6 with good and excellent adaptability was lower in 3-year-old and 4-year-old groups (χ²=59.29, P<0.05).Multiple stepwise linear regression showed that children′s gender (β=0.06), gestational age of birth (β=-0.05), only child (β=-0.04), left-behind child (β=-0.04), the main caregiver (β=-0.06), and the education level of parents (β=0.09, 0.10), whether parents actively pay attention to children′s emotions (β=-0.06) and whether children play with homemade toys (β=-0.04) were the influencing factors of children′s adaptive development quotient.Girls, full-term children, only children, non-left-behind children, children with parents as main caregivers, parents with a high level of education, parents who often take the initiative to pay attention to children′s emotions, and children who play with homemade toys had a higher level of adaptability development quotient. 【Conclusions】 The development level of adaptability in children aged 2 - 6 in China is mostly above the average level and is related to multiple factors.Targeted intervention work can be carried out on relevant factors in order to promote the development of children′s adaptability.

Clinical trial is the gold standard for evaluating the efficacy and safety of interventions; however, it is limited by high costs and long time. Real-world data (RWD) can provide a robust data basis for comparative research, but the quality is uneven. This review introduces the target trial emulation, in which researchers, using RWD and following the design of clinical trials, define exposure and outcome in advance, set eligibility criteria, determine the time zero, estimate sample size, and plan statistical analysis, to enhance the quality of evidence for observational studies. This review preliminarily discusses the standard of evidence quality evaluation in target trial emulation. Then, the target trial emulation is shown through case interpretation.

ObjectiveIn order to improve the recognition accuracy of named entities in medical record texts and realize the effective mining and utilization of medical record knowledge， a Bert-Radical-Lexicon（BRL） neural network model is constructed to recognize medical record entities with respect to the characteristics of medical record texts. MethodWe selected 408 medical records related to hypertension from the the Complete Library of Famous Medical Records of Chinese Dynasties and constructed a dataset consisting of 1 672 medical records by manually labeling. Then， we randomly divided the dataset into three subsets， including the training set（1 004 cases）， the testing set （334 cases） and the validation set（334 cases）. Based on this dataset， we built a BRL model that fused various text features of medical records， as well as its variants BRL-B， BRL-L and BRL-R， and a baseline model Base for experiments. During the model training phase， we trained the above models using the training set to reduce the risk of overfitting. We continuously monitored the performance of each model on the validation set during training and saved the model with the best performance. Finally， we evaluated the performance of these models on the testing set. ResultCompared with other models， the BRL model had the best performance in the medical records named entity recognition task， with an overall recognition precision of 90.09%， a recall of 90.61%， and the harmonic mean of the precision and recall（F1） of 90.35% for eight types of entities， including disease， symptom， tongue manifestation， pulse condition， syndrome， method of treatment， prescription and traditional Chinese medicine（TCM）. Compared with the Base model， the BRL model improved the overall F1 value of entity recognition by 5.22%， and the F1 value of pulse condition entity increased by 6.92%， which was the largest increase. ConclusionBy incorporating a variety of medical record text features in the embedding layer， the BRL neural network model has stronger named entity recognition ability， and thus extracts more accurate and reliable TCM clinical information.
