Objective: To explore the effects of intergenerational parent-child separation on internalizing and externalizing behavioral problems among rural preschoolers aged 3-6 years, so as to provide empirical evidence for formulating targeted intervention strategies and blocking the intergenerational transmission of parent-child separation. Methods: From March to June, 2024, ten kindergartens were selected from rural areas of Nanling County, Wuhu City, Anhui Province, and 2 279 preschool children aged 3- 6 years, along with their fathers, mothers and primary caregivers, were recruited for survey by cluster convenient sampling method. Children s fathers and mothers reported their own childhood parent-child separation information separately. Information on the children s history of psychological and behavioral problems was reported by the primary caregivers. Information of internalizing and externalizing behavioral problems in preschool children was reported with Strengths and Difficulties Questionnaire (SDQ).The Chi square test was used to compare the differences in the detection rates of psychological and behavioral problems among children with different intergenerational continuity of parent-child separation. Binary Logistic regression model was applied to analyze the association between intergenerational continuity of parent-child separation and internalizing and externalizing behavioral problems in preschool children. Results: The detection rate of internalizing behavioral problems was 27.5% and externalizing behavioral problems was 19.1% among rural preschool children. There were significant differences in internalization behavior, externalization behavior, hyperactivity impulse and peer communication problems among preschool children in different types of parent-child separation groups( χ 2=14.29, 8.80, 17.26, 13.84, all P <0.05). Binary Logistic regression analysis showed that after adjusting for covariates such as children s gender, birth weight, and delivery mode, compared with children without separation, intergenerational continuity of parent-child separation group( OR =1.95), only child separation( OR =1.74) were associated with significant higher risk of conduct problems(both P ＜0.05). Parent-child separation intergenerational continuation groups( OR =1.68), only child separation( OR = 1.47) were associated with significant higher risk of peer problems(both P ＜0.05). Both types of parent-child separation experiences significantly increased the risk of children s prosocial behavior problems，among them, the intergenerational continuation group was 1.99 times that of the control group ( OR =1.99), and the childhood only separation group was 2.09 times that of the control group ( OR =2.09)(both P ＜0.05). Compared with children whose parents and children had no experience of parent-child separation, children in the intergenerational continuation group of parent-child separation had increased risks of both internalizing and externalizing behavior problems ( OR =1.53, 1.65, both P <0.05). Conclusion All types of parent-child separation are associated with internalizing and externalizing behavioral problems among rural children aged 3 to 6 years.

Anti-leucine-rich glioma-inactivated 1 （anti-LGI1） antibody autoimmune encephalitis is a relatively common type of limbic encephalitis，and its etiology remains unclear. It is rare for two individuals with a blood relationship to both suffer from encephalitis with positive anti-LGI1 antibodies. This article reports two sisters who lived in different counties and were diagnosed with anti-LGI1 antibody autoimmune encephalitis successively. The two sisters were diagnosed at an age of 64 and 65 years， respectively. During the course of the disease， both patients had epileptic seizures and slow response， but with different clinical manifestations. They had similar results of cranial magnetic resonance imaging and positive anti-LGI1 antibodies in cerebrospinal fluid and serum. The two patients were treated with glucocorticoid shock therapy and gamma globulin infusion during hospitalization，and both patients had a good prognosis. Recent studies have shown that anti-LGI1 antibody encephalitis is associated with genetic susceptibility.For patients with anti-LGI1 antibody encephalitis， it is necessary to inquire about family history and summarize the features of this type of disease， in order to provide better help for clinical practice.

Objective To systematically evaluate the efficacy and safety of traditional Chinese medicine (TCM) compound in treating pulmonary nodules, providing evidence-based medical evidence for TCM intervention in pulmonary nodules. Methods Computer search of PubMed, CNKI, Wanfang, VIP, and SinoMed was conducted to select randomized controlled trials (RCTs) of TCM compound intervention in pulmonary nodules, with the retrieval time from the inception to November 29, 2023. The Cochrane bias risk assessment tool was used to evaluate the quality of the included studies, and Review Manager 5.4 was used for Meta-analysis. Results A total of 18 RCTs were included, covering 8 provinces across the country, with a total sample size of 1301 patients. The TCM compounds used in the included studies all incorporated the method of dissolving phlegm and dissipating nodules. There was a high risk of bias uncertainty in the included studies. Meta-analysis results suggested that TCM compound could significantly reduce the diameter of pulmonary nodules [MD=−1.41, 95%CI (−1.70, −1.13), P<0.001], decrease the number of nodules [MD=−0.37, 95%CI (−0.73, −0.01), P=0.05], alleviate clinical symptoms [MD=−4.84, 95%CI (−6.04, −3.64), P<0.001], and improve lung function [forced expiratory volume in one second (FEV1), MD=0.55, 95%CI (0.09, 1.01), P=0.02; FEV1/forced vital capacity, MD=6.12, 95%CI (4.47, 7.78), P<0.001]. However, there was no statistically significant difference in the probability of malignancy between the experimental group and the control group [MD=−0.01, 95%CI (−0.01, 0.00), P=0.09]. Conclusion TCM compound can significantly reduce the diameter of pulmonary nodules, decrease the number of nodules, alleviate clinical symptoms, and improve lung function, but future multicenter, large-sample, high-quality RCTs are still needed to further explore and verify this conclusion.

[Objective]To clarify the associations between plasma fibrinogen(Fbg)and volumetric bone mineral density(vBMD)as well as osteoporosis measured by quantitative computed tomography(QCT),and to explore the role of plasma Fbg in early screening and diagnosis of osteoporosis.[Methods]Patients with hypertension who were hospitalized in the Department of Endocrinology of Sun Yat-sen Memorial Hospital of Sun Yat-sen University from January 2018 to June 2022 and underwent QCT examinations were included for cross-sectional analysis.The study analyzed the correlation between plasma Fbg and osteoporosis in patients.The diagnostic efficacy of plasma Fbg for osteoporosis was evaluated by the area under the receiver operating characteristic(ROC)curve(AUC).[Results]Totally 441 subjects were included in the analysis,with an average age of 46.0±14.5 years and a prevalence of osteoporosis of 6.4%(28/441).As the level of plasma fibrinogen increased,the incidence of osteoporosis significantly increased(P<0.000 1)while the average bone mineral density of L1 and L2 were significantly decreased(P<0.05).Compared with the first quartile of plasma Fbg(1.99g/L-2.37g/L),the risk of osteoporosis in the fourth quartile of plasma Fbg(3.67g/L-4.46g/L)increased by 8.85 times after adjusting for related confounding factors.[Conclusion]This study found a negative correlation between plasma fibrinogen levels and bone density in patients with hypertension.Plasma fibrinogen levels may serve as a potential screening indicator for osteoporosis,aiding in early diagnosis and therapeutic monitoring.This discovery offers a new perspective for the study of bone metabolic diseases and warrants further investigation.

Objective:To evaluate the effect of acupuncture on postoperative delirium (POD) in diabetic patients undergoing surgery under general anesthesia.Methods:In this randomized controlled trial, 92 diabetic patients of either sex, aged 30-80 yr, with a body mass index of 18-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective surgery under general anesthesia, were divided into 2 groups ( n=46 each) using a table of random numbers: control group (group C) and acupuncture group (group A). Group A received acupuncture at the Baihui (GV20), Shenting (GV24) and Sishencong (EX-HN1) acupoints before anesthesia. The needles were retained for 30 min, with manual stimulation applied every 10 min for 10 s each time. After 4 stimulations, routine anesthesia was carried out. Group C received routine anesthesia only. Regional cerebral oxygen saturation was recorded on admission to the operating room (T 0), after anesthesia induction (T 1), at the start of surgery (T 2), at the end of surgery (T 3), and immediately after tracheal extubation (T 4). The POD developed within 3 days after surgery was assessed. The occurrence of needle-related adverse effects such as fainting, subcutaneous bleeding, and local paresthesia was recorded. Results:Compared with group C, the incidence of POD was significantly reduced, and the regional cerebral oxygen saturation was increased at T 1, 4 in group A ( P<0.05). Conclusions:Acupuncture can decrease the development of POD in diabetic patients undergoing surgery under general anesthesia, which is related to an increase in regional cerebral oxygen saturation.

Objective: To explore the risk factors of allogeneic blood transfusion during lung transplant surgery and prognostic effects of transfusion by analyzing the basic data, surgical details, laboratory tests results, and intraoperative blood transfusion details during the perioperative period of lung transplant, so as to guide clinical blood use. Methods: A retrospective analysis was conducted on the data of 319 patients who underwent lung transplantation surgery in our hospital from January 2022 to December 2023. The patients were divided into a non-transfusion group (n=70) and a transfusion group (n=249) based on their intraoperative blood transfusion status. The clinical data, surgical details, perioperative laboratory results and other relevant preoperative and postoperative parameters were compared between the two groups, and the postoperative prognosis (improvement, non-recovery, and death) was analyzed. Results: After comparison between the two groups of patients, it was found that the non-transfusion group had higher levels of preoperative Hb (g/L)(144.41±17.66 vs 129.78±20.44), preoperative Hct [43.25(40.23, 47.5) vs 40.7(37, 43.55)], preoperative TBIL (μmol/L)[11.45(9.15, 15.3)vs 9.9(6.88, 13.33)], and postoperative PLT (×10 /L)(167.74±64.43 vs 132.37±54.84) than the transfusion group (all P<0.05). The non-transfusion group had lower levels of preoperative pCO (mmHg)[41.4(37.4, 45.8)vs 45.3(40, 52.48)], postoperative TBIL (μmol/L)[25.45(17.68, 33.95)vs 30.8(21.55, 43.05)], postoperative pH (7.41±0.09 vs 7.45±0.10), bilateral lung transplantation [27(38.6%) vs 157(63.1%)], surgical duration (h) [5(4, 7)vs 6.5(5, 8)], use of ECMO [52(74.3%) vs 232(93.2%)], and intraoperative blood loss (mL)[600(500, 800)vs 1 000(800, 1 500)] compared to the transfusion group (all P<0.05). The items with P<0.1 in the compared indicators were included in the binary logistic regression analysis, and the results showed that bilateral lung transplantation, intraoperative blood loss, preoperative TBIL, postoperative PLT, postoperative TBIL, preoperative pCO2, and postoperative pH were significantly correlated with whether blood transfusion was performed (P<0.05). The P values of the Chi-square test for postoperative improvement and mortality in the non transfusion group and transfusion group were both greater than 0.05, indicating no statistically significant difference in the prognosis rate between the two groups of patients. Conclusion: Bilateral lung transplantation, intraoperative blood loss, preoperative TBIL, and preoperative pCO are risk factors for blood transfusion during lung transplantation. Intraoperative blood transfusion has a significant impact on postoperative PLT, postoperative TBIL, and postoperative pH indicators, but has no significant effect on prognosis. A comprehensive evaluation of laboratory indicators and surgical details can help developing blood transfusion strategies more effectively.
