BACKGROUND:LncRNA-TNFRSF13C,an important factor in B cell development and function,is expressed in periodontal tissues of patients with periodontitis,but the specific mechanism is still unclear. OBJECTIVE:To investigate the mechanism of lncRNA-TNFRSF13C regulating miR-1246 on hypoxia-inducible factor 1α in periodontal cells. METHODS:Human periodontal ligament cells(hPDLCs)were treated with lipopolysaccharide and divided into group A(hPDLCs cell lines without transfection),group B(hPDLCs cell lines transfected with TNFRSF13C NC-siRNA),group C(hPDLCs cell lines transfected with TNFRSF13C-siRNA),group D(hPDLCs cell line transfected with miR-1246 mimics),group E(hPDLCs cell line transfected with miR-1246 siRNA),group F(hPDLCs cell line transfected with TNFRSF13C-siRNA+miR-1246 mimics),and group G(hPDLCs cell line transfected with TNFRSF13C-siRNA+miR-1246 siRNA).The relative expression of lncRNA-TNFRSF13C and miR-1246 in each group was detected by qRT-PCR.Cell counting kit-8 assay was used to detect cell viability.Apoptosis was detected by flow cytometry.Expression of hypoxia-inducible factor 1α and vascular endothelial growth factor proteins was detected by western blot.The correlation between lncRNA-TNFRSF13C and miR-1246 was analyzed by Pearson,and the targeting relationship was analyzed by dual-luciferase reporter assay. RESULTS AND CONCLUSION:There was no significant difference in human periodontal ligament cell activity,apoptosis rate and protein indexes between groups A and B(P>0.05).Compared with group B,hPDLCS cell activity in group C was increased,and apoptosis rate and the expression of hypoxia-inducible factor 1α and vascular endothelial growth factor proteins were decreased(P<0.05).Compared with group C,hPDLCS cell activity in group D was decreased,and apoptosis rate and the expression of hypoxia-inducible factor 1α and vascular endothelial growth factor proteins were increased(P<0.05).Compared with group D,the cell activity of group E was increased(P<0.05).The cell activity in group F was lower than that in group E,and the apoptosis rate was reduced in both groups E and F(P<0.05).Compared with group F,the cell activity of group G was increased,and the apoptosis rate and the expression of hypoxia-inducible factor 1α and vascular endothelial growth factor were decreased(P<0.05).LncRNA-TNFRSF13C was positively correlated with miR-1246(P<0.05).Compared with the TNFRSF13C-siRNA group,the fluorescence activity of miR-1246-wt in the TNFRSF13C-NC group was reduced(P>0.05);compared with the miR-1246-NC group,the fluorescence activities of hypoxia-inducible factor 1α-wt and vascular endothelial growth factor-wt in the miR-1246 mimics group were increased(P<0.05).To conclude,down-regulation of lncRNA-TNFRSF13C can promote the activity of periodontal cells treated with lipopolysaccharide,reduce apoptosis,and inhibit hypoxia-inducible factor 1α and vascular endothelial growth factor.The mechanism is related to the regulation of miR-1246 activity.

This paper summarizes Professor WANG Xiuxia's clinical experience in treating hyperprolactinemia using the liver soothing therapy. Professor WANG identifies liver qi stagnation and rebellious chong qi （冲气） as the core pathomechanisms of hyperprolactinemia. Furthermore， liver qi stagnation may transform into fire or lead to pathological changes such as spleen deficiency with phlegm obstruction or kidney deficiency with essence depletion. The treatment strategy centers on soothing the liver， with a modified version of Qinggan Jieyu Decoction （清肝解郁汤） as the base formula. Depending on different syndrome patterns such as liver stagnation transforming into fire， liver stagnation with spleen deficiency， or liver stagnation with kidney deficiency， heat clearing， spleen strengthening， or kidney tonifying herbs are added accordingly. In addition， three paired herb combinations are commonly used for symptom specific treatment， Danggui （Angelica sinensis） with Chuanxiong （Ligusticum chuanxiong）， Zelan （Lycopus lucidus） with Yimucao （Leonurus japonicus） ， and Jiegeng （Platycodon grandiflorus） with Zisu （Perilla frutescens）.

Sterilization is one of the key links in the production of traditional Chinese medicine,and it is also an important factor to ensure the safety,effectiveness and quality control of traditional Chinese medicine.Traditional sterilization techniques such as moist heat sterilization are limited in many cases due to their inherent shortcomings.In contrast,irradiation sterilization has attracted more and more attention due to its advantages of fast,efficient,strong sterilization and low cost.However,the chemical composition of traditional Chinese medicine is complex,due to the radioactivity and strong penetration of irradiation,after a certain dose of irradiation,its chemical composition and pharmacological activity may change.At present,there is still a lack of systematic research on the changes of chemical composition,effectiveness and safety of traditional Chinese medicine after irradiation sterilization.Based on the research status of 60Co-γ ray and electron beam irradiation sterilization in the sterilization of traditional Chinese medicine in recent years,this paper reviews the effects of irradiation on the effectiveness of traditional Chinese medicine,the detection methods of irradiation and the safety evaluation,in order to provide some reference for the subsequent application of irradiation sterilization of traditional Chinese medicine.

The traditional acute care model, focused on disease diagnosis and treatment, is struggling to meet the complex needs of elderly patients at the end of life, encompassing physical, psychological, social, and spiritual aspects.Hospice care, designed to enhance the quality of life and death for patients in this stage, offers a suitable service model for the elderly.Hospice care for elderly patients at the end of life should be centered around the patient, honoring their preferences, and delivering comprehensive care that addresses their overall well-being.The lack of knowledge about hospice care among healthcare professionals often hinders its implementation, negatively impacting the quality of life for these patients.This article aims to outline the key features of hospice care services for elderly patients at the end of life, serving as a valuable reference for clinical practice.

To improve the understanding of the special imaging features of pulmonary cryptococcosis in immunocompetent individuals and reduce misdiagnosis and missed diagnosis through the analysis of rare clinical cases and literature review. We reported a case of normal immunocompetent pulmonary cryptococcosis with pulmonary hypertension and COVID-19 weak positive nucleic acid during convalescence, CT scan of the lungs revealed rare features similar to pulmonary interstitial changes. Literature was reviewed to further discuss pulmonary cryptococcosis's clinical symptoms, imaging manifestations, diagnosis, and treatment outcome. The patient with severe aortic stenosis needed to be treated by surgery as soon as possible. Secondary pulmonary infection, subacute onset, and clinical manifestations were nonspecific, and empirical anti-infection treatment at the beginning of the disease was not effective. The timely revision of the examination confirmed that the predominant causative agent was Cryptococcus neoformans, and prompt administration of antifungal treatment facilitated surgical intervention and yielded favorable therapeutic outcomes. Literature review revealed that it is rare for pulmonary cryptococcosis in immunocompetent patients to present with pulmonary interstitial changes on CT findings.Pulmonary cryptococcosis presents with non-specific clinical symptoms and diverse imaging features, making it prone to mixed infection and requiring high vigilance. In this case, the immunocompetent patient's pulmonary CT findings exhibited changes resembling those in immunodeficient patients with pulmonary cryptococcosis. The underlying pathogenic mechanism needs to be further explored.

Deinagkistrodon acutus(also known as the five-paced viper and the traditional Chinese medicine ingredient is called Agkistrodon) venom is a viscous liquid from the venom glands of the Deinagkistrodon acutus. It contains a variety of protein and peptide components such as phospholipase A2, serine protease, metalloproteinase, C-type lectin, L-amino acid oxidase, and has a variety of biological activities, playing an important role in anti-tumour, anti-thrombotic, anti-inflammatory and anti-bacterial activities. In recent years, snake venom research has become increasingly widespread, but there is still a lack of comprehensive and systematic studies on snake venom from Deinagkistrodon acutus. In this paper, the source, identification, active ingredients, toxicity studies and quality researches of Deinagkistrodon acutus venom are summarized and analysed by searching the related research progress, in order to provide reference for further development and utilization of Deinagkistrodon acutus venom.

Objective:To investigate the clinical features of patients with epilepsy in Neurosurgery Outpatient and influencing factors for their seizure control.Methods:Six hundred and seventy-three epilepsy patients admitted to Neurosurgery Outpatient of 6 hospitals including Fifth Affiliated Hospital of Zhengzhou University from September 2017 to December 2022 were chosen. Clinical data (including general demographic data, education level, onset age, onset cycle and duration, course of onset, family annual income and seizure control) were collected using a questionnaire prepared by He'nan Epilepsy Systematic Diagnosis and Treatment Center to summarize the clinical features. Univariate and multivariate Logistic regressions were used to analyze the influencing factors for their seizure control.Results:(1) In these 673 epilepsy patients, 50 (7.4%), 78 (11.6%), 192 (28.5%), 100 (14.9%), 68 (10.1%), 72 (10.7%) and 113 (16.8%), respectively, were <1 year old (infant stage), 1-2 years old (children stage), 3-5 years old (preschool stage), 6-16 years old (juvenile stage), 17-39 years old (young stage), 40-64 years old (middle-aged stage) and ≥65 years old (elderly stage). In the past medical treatment history, 23.0% (155/673) patients did not receive intervention, 72.4% (487/673) received medication, and 4.6% (31/673) received surgical treatment; 55.9% (376/673) had good seizure control and 44.1% (297/673) had poor seizure control. (2) Secondary education ( OR=2.199, 95% CI: 1.037-15.221, P=0.033), primary education or below ( OR=3.544, 95% CI: 2.101-21.343, P=0.012), daily seizures ( OR=4.788, 95% CI: 1.369-33.103, P=0.011), each seizure lasted ≥3 min ( OR=4.179, 95% CI: 3.338-18.550, P=0.003), course of disease≥3 years ( OR=0.199, 95% CI: 0.077-0.602, P=0.001), course of disease for 1-3 years ( OR=0.379, 95% CI: 0.108-0.882, P=0.031), and currently taken antiepileptic drugs for 3 or more ( OR=6.237, 95% CI: 2.195-17.837, P=0.001) were independent risk factors for poor seizure control in epilepsy patients. Conclusion:In Neurosurgery Outpatient, children with diseases before childhood enjoy the largest proportion; drug therapy remains the main treatment; low education level, short seizure cycle, long duration of attack, long course of disease, and multiple drugs used in these patients imply poor anti-epileptic effecacy.

Objective:To explore the morbidity, clinical features and mortality of unilateral pulmonary edema (PE) in the intensive care unit (ICU).Methods:Clinical data of PE patients in ICU between January 2018 and January 2021 were retrospectively collected. All patients were divided into the bilateral PE and unilateral PE groups according to imaging manifestations. Etilogy, clinical performance, cardiac ultrasound parameters, complications, treatment and prognosis were compared between the two groups. Binary logistic regression analysis was used to screen out the risk factors of death.Results:Of the 314 PE patients, 14 (4.5%) were unilateral PE patients , and 11 (78.5%) were right-sided unilateral PE. There were no differences in age, gender, heart rate, respiratory rate and left ventricular eject fraction between the unilateral and bilateral PE groups. Compared with the bilateral PE group, systolic and diastolic blood pressure were significantly lower in the unilateral PE group [128 (102.7-138) mmHg vs. 135 (116-166) mmHg, 72 (54-88.2) mmHg vs. 82 (69-97.7)mmHg, respectively]. The incidence of cardiac arrest and hospital mortality were higher in the unilateral PE group [28.6% vs. 8.0%, 42.9% vs. 10%, all P<0.05]. Binary logistic regression analysis showed that age, unilateral PE, and use of vasoactive agent were associated with poor prognosis. Odds ratio of unilateral PE and use of vasoactive agent were 17.78 and 11.67, respectively. Conclusions:Unilateral PE is not rare, which is an independent risk factors for mortality and should be promptly recognized to avoid delays in treatment.

Objective:To investigate the relationship between the serum alkaline phosphatase (ALP), prostate specific antigen (PSA) and bone metastasis in initially diagnosed prostate cancer (PCa) patients in different ISUP(International Society of Urological Pathology)groups.Methods:The 368 initial diagnosed prostate cancer patients recruited from January 2013 to December 2018 were retrospectively analyzed, including 247 cases in the Third Affiliated Hospital of Sun Yat-sen University, 111 cases in the Yuebei People's Hospital Affiliated to Medical College of Shantou University and 10 cases in Shenzhen Hospital of Southern Medical University. According to whether there was bone metastasis at the initial diagnosis, it was divided into 230 cases in the bone metastasis group and 138 cases in the non bone metastasis group. There was no significant difference between the two groups in age [(71.9±9.4) years and (71.2±8.7) years], body mass index (BMI) [(23.1±3.7) kg/m 2 and (23.7±2.6) kg/m 2]. There were significant differences in PSA [(307.3±847.0) ng/ml and (84.5±257.3) ng/ml] and ALP [(174.5±270.8) U/L and (71.0±23.2) U/L] between the two groups. In different PSA subgroups, there were 45 cases in PSA <10 ng/ml, 35 cases in PSA 10-20 ng/ml and 288 cases in PSA >20 ng/ml. The differences of ALP and PSA between bone metastasis group and non-bone metastasis group based on different ISUP stratification were analyzed, ROC curves were used to predict their risks of bone metastasis. Results:There were 3(1.3%), 22(9.6%), 34(14.8%), 85(37.0%) and 86 (37.4%) prostate cancer patients with bone metastasis from ISUP group 1 to 5, and 14(10.1%), 19(13.8%), 29(21.0%), 32(23.2%) and 44(31.9%) without bone metastasis, respectively. There was significant difference in the serum ALP levels between the bone metastasis group and the boneless metastasis group in the ISUP group 4(157.6±207.7 vs. 66.5±17.0) and 5(189.4±257.5 vs. 69.2±18.4)( P<0.001) and PSA levels had difference in the ISUP group 3(240.3±313.0 vs. 42.4±42.1), 4(152.3±184.5 vs. 44.7±33.3) and 5(435.2±1006.3 vs. 60.8±84.8)( P<0.001). There was statistically significant between the bone metastasis group and the without(336.1±882.2 vs. 139.3±328.1) when PSA>20 ng/ml( P=0.006). ROC curve analysis: the cut-off values of ALP were 115.5, 109.0, 75.5 and 86.0 U/L from ISUP group 2 to 5 respectively, the sensitivity was 23.8%, 56.5%, 66.4% and 50.6% respectively, the specificity was 99.7%, 93.4%, 78.3% and 89.2% respectively, and the accuracy were 59.4%, 73.1%, 69.7% and 63.3%, respectively. The cut-off values of PSA were 39.5, 93.1, 54.2 and 28.9 ng/ml from ISUP group 2 to 5 respectively, the sensitivity was 64.4%, 68.4%, 87.4% and 88.3% respectively, and the specificity was 79.5%, 90.6%, 63.7% and 61.6% respectively, and the accuracy were 71.6%, 78.1%, 80.1% and 79.2%, respectively. Conclusion:ALP increased significantly in ISUP group ≥4 and PSA in ISUP group ≥3, which related to bone metastasis in patients with initial diagnosed prostate cancer.
