Objective To detect the levels of serum collagen type Ⅰ alpha 1 chain(COL1A1)and collagen type Ⅰ alpha 2 chain(COL1A2)in patients with intracranial aneurysm(IA),and explore their correlations with aneurysm rupture.Methods A total of 110 IA patients admitted to our hospital were regarded as the IA group and another 100 volunteers who underwent physical examination in our hospital were regarded as the control group.The expression levels of serum COL1A1 and COL1A2 were detected by ELISA.The IA patients were divided into the ruptured group(n=66)and unruptured group(n=44)according to the presence or absence of aneurysm rupture,and the clinical data and expression levels of serum COL1A1 and COL1A2 were compared between the two groups.The expression levels of serum COL1A1 and COL1A2 in patients with different Hunt-Hess grades were compared.The risk factors of aneurysm rupture in patients with IA were analyzed by multivariate Logistic regression analysis.The predictive value of serum COL1A1 and COL1A2 for aneurysm rupture in patients with IA were evaluated by receiver operating characteristic(ROC)curve.The correlation of serum COL1A1 and COL1A2 with Hunt-Hess grade for patients in rupture group was analyzed by Spearman correlation analysis.Results The expression levels of serum COL1A1 and COL1A2 for patients in the IA group were significantly higher than those in the control group(P<0.05).The number of patients with hypertension,diabetes mellitus,hyperlipidemia,aneurysm diameter>10 mm,and the expression levels of serum COL1A1 and COL1A2 in the rupture group were significantly more/higher than those in the unruptured group(P<0.05).The expression levels of serum COL1A1 and COL1A2 in patients with Hunt-Hess grades from Ⅲ to Ⅳ were significantly higher than those in patients with grades from Ⅰ to Ⅱ(P<0.05).The expression levels of serum COL1A1 and COL1A2 for patients in the rupture group were positively correlated with Hunt-Hess grade(r=0.562,0.414,P<0.05).Multivariate Logistic regression analysis showed that hypertension,diabetes mellitus,aneurysm diameter>10 mm,and increased expression levels of COL1A1 and COL1A2 were risk factors for aneurysm rupture in IA patients(P<0.05).The area under the curve(AUC)of aneurysm rupture predicted by serum COL1A1 and COL1A2 together was significantly higher than that predicted by COL1A1 alone(Z=1.905,P=0.028)and COL1A2 alone(Z=1.754,P=0.040).Conclusion The increased expression levels of serum COL1A1 and COL1A2 are risk factors for aneurysm rupture in patients with IA,and their combined prediction of aneurysm rupture in IA patients has certain clinical value.

Objective To compare the efficacy of single-port laparoscopic unilateral salpingectomy and adnexectomy(ovary+fallopian tube)via different approaches,and to explore the safety and feasibility of single-port single-handed laparoscopy without access platform.Methods A total of 94 patients who underwent unilateral salpingectomy and 78 patients who underwent unilateral adnexectomy in our hospital from August 2021 to November 2022 were selected and randomly divided into the single-port single-handed without access platform group,the single-port double-handed without access platform group,and the single-port with access platform group,respectively.The operation time,intraoperative blood loss,postoperative morbidity,postoperative anal exhaust time,postoperative hospitalization time,total hospitalization cost,incision length,postoperative pain visual analogue scale(VAS)score,surgical complications,postoperative body image scale(BIS),and cosmetic score(CS)of patients in the three groups were observed and compared.Results There was no statistically significant difference in operative time,intraoperative blood loss,postoperative morbidity,postoperative anal exhaust time,postoperative hospitalization time,and surgical complications among the three groups(P>0.05).There were statistically significant differences in total hospitalization cost,incision length,postoperative VAS score,postoperative BIS score,and postoperative CS among the three groups(P<0.05).Conclusion Single-port single-handed laparoscopy salpingectomy and adnexectomy without access platform is a safe and feasible surgical method,which has the advantages of smaller incision,less hospitalization cost,and higher incision satisfaction than single-port surgery with access platform and single-port double-handed laparoscopic surgery without access platform.

Pseudoaneurysm is a rare yet potentially life-threatening condition,typically arising as a complication of myocardial infarction,cardiac surgery,trauma,or infection.The incidence of postoperative pseudoaneurysms in congenital heart disease patients is exceedingly low.Traditional surgical intervention involves excising the pseudoaneurysm and repairing its base;however,this approach entails significant surgical trauma and elevated risk.This case report details the diagnosis of a left ventricular pseudoaneurysm(LVPA)in a 6-month-and-10-day-old child following corrective surgery for congenital heart disease.At 7 weeks of age,the patient underwent repair for ventricular septal defect,atrial septal defect,and pulmonary valve dilation.A LVPA was identified three months postoperatively.Four months after the initial procedure,successful percutaneous closure of the pseudoaneurysm was achieved via transfemoral access under transthoracic echocardiographic guidance.Postoperative follow-up confirmed optimal positioning of the occluder and satisfactory recovery in the child.This case underscores the efficacy and minimal invasiveness associated with ultrasound-guided percutaneous closure for newly developed LVPA in pediatric patients.

Through collecting the relevant records of "brain" in ancient traditional Chinese medicine literature, the potential structure and function of the "motor system of brain-meridian-muscle region" and "perception system of brain-meridian-cutaneous region" of the human body are analyzed preliminarily. In view of the characteristics of the symptoms of stroke sequela, focusing on the differentiation of disease location and associated with the identification of disease property, the pathogenesis of stroke is determined, "malnutrition of the sea of marrow, dysfunction of meridian muscle region and disharmony of the nutrient and the defensive in the meridian cutaneous region", while, the basic principle of treatment is formulated, "filling up the marrow, replenishing the brain, regulating meridian muscle regions, tonifying qi and facilitating blood circulation in meridians and collaterals". Based on the above, the acupoints selected in treatment and the techniques of acupuncture and moxibustion are clarified. This article presents the references for the clinical practice of acupuncture and moxibustion and provides the individual therapeutic regimen for stroke patients.

There was no significant difference in the prevalence of sarcopenia and sarcopenic obesity between men and women, but there was a significant difference in the prevalence of osteoporosis between men and women. The prevalence of all three groups reached the peak in the age group above 60, and the difference was statistically significant.The risk factor for osteoporosis was sarcopenia and sarcopenic obesity. Conclusion Among adults of Han nationality in Liaoning, the prevalence of sarcopenic obesity,sarcopenia and osteoporosis is significantly different in age. Bone condition is affected by fat mass and muscle mass.

Zearalenone(ZEN) is a toxic metabolite produced by Fusarium culmorum, F. graminearum, F. tricinctum, and other fungi, with estrogenic characteristics. Exposure to or ingestion of ZEN during pregnancy can cause reproductive dysfunction, miscarriage, stillbirth, and malformation, and seriously endanger human life and health. The detection methods for ZEN in the Chinese Pharmacopoeia(2020 edition) are liquid chromatography(LC) and liquid chromatography-mass spectrometry(LC-MS), and it is stipulated that ZEN should not exceed 500 μg in 1 000 g of Coicis Semen. Although these detection methods by instruments can achieve the qualitative and quantitative analysis of ZEN in Coicis Semen, their high detection cost and long periods hinder the rapid screening of a large number of samples in the field. In this study, the synthesized ZEN hapten was conjugated with bovine serum albumin(BSA) and ovalbumin(OVA) to obtain the complete ZEN antigen. By virtue of antibody preparation techniques, ZEN monoclonal antibody 4F6 was prepared, which showed 177.5%, 137.1%, and 109.7% cross-reactivity with ZEN structural analogs zearalanol, zearalenone, and α-zearalenol, respectively, and no cross-reactivity with other fungal toxins such as aflatoxin. Direct competitive enzyme-linked immunosorbent assay(dcELISA) based on ZEN monoclonal antibody 4F6 was developed for the determination of ZEN in Coicis Semen with an IC_(50) of 1.3 μg·L~(-1) and a detection range of 0.22-21.92 μg·L~(-1). The recoveries were 83.91%-105.3% and the RSD was 4.4%-8.0%. The established dcELISA method was used to determine the ZEN residuals in nine batches of Coicis Semen samples, and the results were validated by LC-MS. The correlation between the two detection methods was found to be 0.993 9, indicating that the established dcELISA could be used for the rapid qualitative and quantitative detection of ZEN residuals in Coicis Semen.

Objective: To investigate the correlation between CLOCK and BMAL1 genes and MEN2 medullary thyroid carcinoma (MTC). Methods: Thirteen cases with MEN2 MTC and thirteen cases with non-MEN2 MTC were selected who were treated in the Yantai Yuhuangding Hospital between January 2013 and September 2021. Clinical indicators such as blood calcitonin level, tumor diameter and metastatic lymph node of patients were collected. The expression differences of CLOCK and BMAL1 between MEN2 MTC and para-carcinoma tissue as well as between MEN2 MTC and non-MEN2 MTC were detected by immunohistochemistry and qPCR. The correlation between lymph node metastasis and CLOCK or BMAL1 expression was analyzed. Protein-protein interaction (PPI) network analysis combined with qPCR and correlation analysis was used to explore the expression regulation relationship between RET and circadian clock genes. The rhythm disorder of MEN2 cells was verified by lipopolysaccharide cell stimulation experiment after dexamethasone rhythm synchronization. Results: MEN2 MTC exhibited typical RET gene mutation. The mean blood calcitonin level, the tumor diameter and the number of metastatic lymph nodes of patients with MEN2 MTC were higher than those of patients with non-MEN2 MTC (t value was 2.76, 2.53, 2.26, all P<0.05). Immunohistochemical results showed that the expression levels of CLOCK and BMAL1 in MEN2 MTC were higher than those in non-MEN2 MTC, while negatively expressed in para-cancerous thyroid follicle. qPCR displayed that the expression of CLOCK gene in cancer tissues was higher than that in non-MEN2 MTC and para-cancerous tissues (t value was 2.68 and 2.86, all P<0.05); the expression of BMAL1 gene in MEN2 MTC was higher than that in non-MEN2 MTC and para-cancerous tissues (t value was 2.21 and 2.35, all P<0.05). Correlation analysis showed that the expression levels of CLOCK and BMAL1 genes were positively correlated with the number of lymph node metastases in patients with MEN2 MTC (r=0.65, P<0.001; r=0.52, P=0.005). PPI network analysis indicated that the expression of CLOCK gene was positively correlated with the abnormal expression of RET gene (r=0.96, P<0.001). With lipopolysaccharide to stimulate cultured cells in vitro after dexamethasone rhythm synchronization, the expressions of CLOCK and BMAL1 in MEN2 MTC cells (0.47±0.22 and 2.60±1.48) at 12 hours of synchronization were significantly lower than those in para-cancerous tissues (1.70±1.62 and 8.23±2.52), the difference was statistically significant(t=5.04, P=0.007; t=3.34, P=0.029). Conclusion: CLOCK and BMAL1 are correlated with the occurrence and development of MEN2 MTC, and may be potential targets for the development of new therapeutic strategies for MEN2 MTC.
