Objective To analyze the expression of microRNA(miR)-200a and miR-4652-3p in cerebrospinal fluid of patients with tuberculous meningitis(TBM)and their predictive value for disease severity and prognosis.Methods A total of 187 patients with tuberculous meningitis who visited Qingdao Chest Hospital from January 2018 to December 2022 were regarded and separated into stage Ⅰ(n=62),stage Ⅱ(n=76)and stage Ⅲ(n=49)according to the severity of the condition.There were 131 cases in the good prognosis group and 56 cases in the poor prognosis group according to the prognosis.The qRT-PCR method was applied to detect the expression levels of miR-200a and miR-4652-3p in cerebrospinal fluid.Spearman method was used to analyze correlation among miR-200a,miR-4652-3p and clinical data.ROC curve was applied to analyze the predictive value of cerebrospinal fluid miR-200a and miR-4652-3p levels in evaluating the severity and prognosis of tuberculosis meningitis patients.Multivariate logistic regression was applied to analyze the influencing factors of poor prognosis in patients.Results The expression levels of miR-200a(1.05±0.14,0.91±0.14,0.76±0.13)and miR-4652-3p(0.92±0.11,0.78±0.11,0.65±0.10)in the cerebrospinal fluid of patients with stage Ⅰ,Ⅱ,and Ⅲ tuberculous meningitis were decreased sequentially,and the differences were significant(F=61.079,87.203,all P＜0.05).The expression levels of miR-200a(0.95±0.14)and miR-4652-3p(0.82±0.11)in cerebrospinal fluid of patients with good prognosis tuberculous meningitis were higher than those of patients with poor rognosis(0.84±0.13,0.73±0.10),and the differences were statistically significant(t=5.025,5.262,all P＜0.05),while the levels of cerebrospinal fluid adenosine deaminase,TNF-α,IL-23,LTB4,CRP and mRS scores in patients with good prognosis were lower than those in patients with poor prognosis(t=5.649,7.721,11.150,9.455,11.314,14.407,all P＜0.05).There was a positive correlation between the levels of miR-200a and miR-4652-3p in cerebrospinal fluid of patients with tuberculous meningitis(r=0.405,P＜0.001).The levels of miR-200a and miR-4652-3p in cerebrospinal fluid were negatively correlated with LTB4,TNF-ot,CRP,mRS scores,IL-23 and adenosine deaminase(r=-0.472,-0.466,-0.461,-0.435,-0.422,-0.419;-0.459,-0.531,-0.471,-0.417,-0.513,-0.408,all P＜0.05).The AUC(95％CI)of miR-200a and miR-4652-3p to assess disease severity were 0.881(0.825～0.923)and 0.878(0.822～0.921),respectively.The AUC(95％CI)of both combination in assessing the severity of patients was 0.945(0.902～0.973),which was higher than the single detection,and the differences were significant(Z=3.008,2.960,all P=0.003).The AUC(95％CI)of poor prognosis patients evaluated by cerebrospinal fluid miR-200a and miR-4652-3p levels were 0.749(0.681～0.809)and 0.756(0.688～0.816),and the AUC of poor prognosis patients evaluated by both combination was 0.839(0.778～0.889),which was higher than that measured separately,and the differences were significant(Z=2.994,2.697,P=0.003,0.007).Adenosine deaminase[OR(95％CI):1.106(1.033～1.185)],miR-200a[OR(95％CI):0.529(0.369～0.744)],miR-4652-3p[OR(95％CI):0.471(0.310～0.715)],C-reactive protein[OR(95％CI):4.423(1.459～13.412)],TNF-α[OR(95％CI):1.196(1.061～1.348)],IL-23[OR(95％CI):4.809(1.086～3.013)],and LTB4[OR(95％CI):1.327(1.064～1.655)]were influencing factors for poor prognosis in patients with tuberculous meningitis(all P＜0.05).Conclusion The expressions of miR-200a and miR-4652-3p in cerebrospinal fluid of patients with tuberculous meningitis were down-regulated,and they were closely related to the severity and prognosis of the disease.The combination of the miR-200a and miR-4652-3p could better predict the severity and prognosis of tuberculous meningitis,which may have a certain clinical value.

The Ehlers-Danlos syndrome(EDS)is a rare inherent connective tissue disorder.The prev-alence of EDS in the population is estimated at one out of ten thousand to one out of a hundred thousand.The vascular EDS(vEDS)are rare among the subtypes but are the worst in prognosis.The article reports a case of vEDS admitted to the hospital.The patient was a young man complaining of a sudden onset of aphasia in right hemiparalysis and severe left abdominal pain for unknown reasons.The diagnosis was made after the genetic testing.The patient suffered from vEDS.Then,the multi-disciplinary team(MDT)made a treatment plan tailored to this young patient.The complexity in classification and delusive presentations of the EDS make the correct diagnosis very challenging.This article hopes to report this case and to share the experiences to the bet-ter understanding of this disease.

Surgical operation is the main treatment of oral and maxillofacial tumors.Dysphagia is a common postoperative complication.Swal-lowing disorder can not only lead to mis-aspiration,malnutrition,aspiration pneumonia and other serious consequences,but also may cause psychological problems and social communication barriers,affecting the quality of life of the patients.At present,there is no systematic evalua-tion and rehabilitation management plan for the problem of swallowing disorder after oral and maxillofacial tumor surgery in China.Combining the characteristics of postoperative swallowing disorder in patients with oral and maxillofacial tumors,summarizing the clinical experience of ex-perts in the field of tumor and rehabilitation,reviewing and summarizing relevant literature at home and abroad,and through joint discussion and modification,a group of national experts reached this consensus including the core contents of the screening of swallowing disorders,the phased assessment of prognosis and complications,and the implementation plan of comprehensive management such as nutrition management,respiratory management,swallowing function recovery,psychology and nursing during rehabilitation treatment,in order to improve the evalua-tion and rehabilitation of swallowing disorder after oral and maxillofacial tumor surgery in clinic.

Objective:To understand the current status and its associated factors of dual use of e-cigarettes and cigarettes among adolescents in Shandong Province and explore the reasons for dual use behavior.Methods:A self-administered survey was conducted among 7 999 middle school students who were selected by stratified multi-stage cluster sample method. Data were weighted and analyzed by the SPSS 25.0 complex program.Results:In Shandong Province, the prevalence rates of attempting and current dual use of e-cigarettes and cigarettes among adolescents appeared as 7.7% and 1.3%, respectively. Male, friends smoking, and secondhand smoke exposure in the past 7 days were risk factors for dual use. Compared with cigarette smokers, dual users have no differences in cognition and behavior in quitting smoking ( P>0.05). The main reason for dual users to smoke e-cigarettes was curiosity. Conclusions:Dual use of e-cigarettes and cigarettes is common among adolescents in Shandong Province, and its influencing factors are similar to traditional cigarettes. Dual use is not a transitional stage for smoking cessation. Dual users are more likely to continue smoking in the future, which should be paid attention and concern.

Hypertriglyceridemia-associated acute pancreatitis is an inflammatory disorder of exocrine pancreas caused by metabolism disturbances of triglyceride-rich lipoproteins.Currently,hypertriglyceridemia-associated acute pancreatitis is characterized by an escalating incidence rate,a tendency for more severe cases,and a lack of therapeutic drugs.Traditional Chinese medicine has distinct advantages in treating this disease,but its theoretical framework has not yet been established.Hypertriglyceridemia-associated acute pancreatitis manifests itself as a febrile disease,aberrant accumulation of fat and turbidity may stem from dietary imbalances and visceral dysfunction in ordinary individuals.The prolonged accumulation of fat and turbidity can transform into turbid pathogen,subsequently engendering heat,constituting a pivotal pathogenic factor.Throughout the progression of the disease,the fiery pathogen consumes the fat and turbidity,resulting in the generation of toxic heat,which is a crucial mechanism in the exacerbation of the disease severity.Thus,this article posits therapeutic principles aimed at averting the transformation of fat and turbidity into turbid pathogen and counteracting toxic heat in this disease.This article reviews two key theories from traditional Chinese medicine classics relevant to hypertriglyceridemia-associated acute pancreatitis:the theory of fat-turbidity associated with hypertriglyceridemia and the febrile disease related to acute pancreatitis.Combining these traditional theories with modern research on the mechanisms that intensify hypertriglyceridemia-associated acute pancreatitis and the corresponding targets of traditional Chinese medicine,it suggests that the pathogenesis of"fat-turbidity-toxic heat"serves as the theoretical basis of traditional Chinese medicine for the aggravated severity of hypertriglyceridemia-associated acute pancreatitis.The article aims to offer new insights for the treatment of hypertriglyceridemia-associated acute pancreatitis.

To evaluate the application value of metal clip combined with suture and rubber coil as a simple traction device in endoscopic submucosal dissection (ESD) for intestinal mucosal lesions, a total of 56 patients with early colonic cancer and precancerous lesions who received ESD in Jiangyin People's Hospital from January 2021 to July 2022 were randomly divided into the control group ( n=28, conventional ESD) and the traction group ( n= 28, suture and rubber coil as a simple traction device). The total time of ESD, mucosal dissection time, number of submucosal injections, complete resection rate and complications were compared between the two groups. The operation time of the traction group was shorter than that of the control group (74.64±33.25 min VS 117.18±35.75 min, t=4.61, P<0.001). The desection time of mucosa in the traction group was shorter than that in the control group (51.61±24.87 min VS 99.11±32.73 min, t=6.11, P<0.001). The number of submucosal injection in the traction group was less than that of the control group with significant difference (1.68±1.16 VS 4.96±1.41, t=9.57, P<0.001). There was no significant differences in operation area, complete resection rate or complication between the two groups ( P>0.05). The traction assistance technology of metal clip combined with suture and rubber coil can reduce the technical difficulty of colonic ESD and shorten the operation time.

OBJECTIVES: To investigate the synergistic inhibitory effects of AKBA and doxorubicin on malignant phenotype of triple-negative breast cancer (TNBC) MDA-MB-231 cells. METHODS: CCK-8 assay was used to determine the 48-h IC₅₀ of AKBA and doxorubicin in MDA-MB-231 cells, and SynergyFinder was employed to calculate the synergistic index and the optimal concentrations of the two agents. MDA-MB-231 cells treated with AKBA (22.5 μmol/L), doxorubicin (0.84 μmol/L) or their combination were examined for changes in cell proliferation, migration, invasion and apoptosis using Transwell migration, scratch assay, clone generation, RT-qPCR and Western blotting. Network pharmacology analysis was conducted to identify the downstream targets of AKBA in TNBC. In nude mouse models bearing subcutaneous MDA-MB-231 cell xenografts, the effects of normal saline, AKBA (50 mg/kg), doxorubicin (2.5 mg/kg), and AKBA combined with doxorubicin on xenograft growth and histopathology were observed. RESULTS: The IC₅₀ of AKBA and doxorubicin in MDA-MB-231 cells at 48 h was 45.15±0.97 μmol/L and 0.42±0.99 μmol/L, respectively. SynergyFinder confirmed the synergistic effect of AKBA and ADR with a ZIP>10. The combined treatment with AKBA and doxorubicin significantly inhibited the proliferation, migration and invasion, promoted apoptosis of MDA-MB-231 cells, and effectively suppressed xenograft growth in nude mice. Network pharmacology analysis predicted that AKBA affects the progression of TNBC through its downstream target AKBA. CONCLUSIONS AKBA combined with doxorubicin inhibits proliferation, migration and invasion, promotes apoptosis of MDA-MB-231 cells and suppresses MDA-MB-231 cell xenograft growth in nude mice. The combined use of AKBA can attenuate the toxic effects of doxorubicin in nude mice.

A large spontaneous mass on the dorsal abdomen near the hip joint was found in an aged female Tupaia belangeri subsp. yaoshanensis after 5 years of routine feeding. The tumor in the diseased tree shrew was huge, with an intact surface and no ulceration; however, it caused inconvenience in movement while maintaining a good mental state. After inhalation anesthesia with isoflurane (2%-4%), the tree shrew was euthanized after the tree shrew entered deep anesthesia. Anatomical dissection of the tumor, the tumor boundary was unclear and infiltrated into surrounding tissues. HE staining showed that small focal pleomorphism and large areas of adipocytes were seen in the tumor tissue. The pleomorphic sarcoma area was mainly composed of atypical epithelioid cells with easily visible nuclear divisions. The size of the adipocytes was significantly different, and more pleomorphic adipocytes were seen. The cell volume was large, the nucleus was deeply stained and deformed, the edge was impressed, and the cytoplasm was seen with multiple vesicular lipid droplets. Immunohistochemical results showed that the tumor cells were positive for Vimentin, the small focal polymorphic adipocyte nucleus was positive for S-100, and Ki-67 exhibited a higher proportion of positivity. Combined with HE staining and immunohistochemical results, the spontaneous tumor in this tree shrew was comprehensively diagnosed as pleomorphic liposarcoma.

OBJECTIVE To explore the efficacy of Sour Jujube Seed Decoction combined with Huanglian Wendan Decoction on adult chronic insomnia and its effect on hypnotic withdrawal.METHODS 187 patients with chronic insomnia were included for anal-ysis,including 102 in the traditional Chinese medicine(TCM)group and 85 in the western medicine group.The TCM group was trea-ted with Sour Jujube Seed Decoction combined with Huanglian Wendan Decoction,while the western medicine group was treated with benzodiazepine under the consideration of doctor.The intervention period was 1 month,with assessments using the Pittsburgh Sleep Quality Index(PSQI)conducted before and after the intervention.Follow-up evaluations were performed at 3 months and 6 months re-spectively after the intervention.RESULTS There was no significant difference between the two groups at baseline.After the inter-vention,the PSQI scores of patients in both groups were significantly improved(P<0.01).Among them,the TCM group was better than the western medicine group in the improvement of sleep quality and sleeping pills,total PSQI score reduction(P<0.01).The re-sults of linear regression analysis showed that after controlling for confounding factors,the regression coefficients of the TCM group in two different models were1.821 and 1.922 respectively,and the former was statistically significant(P<0.05).By screening patients who took hypnotics at baseline in the TCM group and comparing them with those in the western medicine group,the influencing factors of hypnotic withdrawal were analyzed.During the 3-month follow-up,25 out of 39 patients in the TCM group and 17 out of 80 patients in the western medicine group had hypnotic withdrawal(χ2= 19.25,P<0.001);during the 6-month follow-up,23 of the 39 patients in the TCM group and 18 of the 79 patients in the western medicine group had hypnotic withdrawal(χ2= 13.53,P<0.001),the with-drawal rate of patients in the TCM group was significantly higher than that in the western medicine group.Further regression analysis showed that after adjusting for confounding factors,the results showed that the western medicine group had a significantly higher rate of not withdrawal than the TCM group at 3 months(OR=5.50,95%CI:2.30～13.72)and 6 months(OR=6.43,95%CI:2.54～17.77),and the results were statistically different(P<0.05).CONCLUSION Sour Jujube Seed Decoction combined with Huangli-an Wendan Decoction is effective in treating adult chronic insomnia and assisting in hypnotic withdrawal.
