Objective To analyze the effect of different retained dosage of lauromacrogol within the thyroid cyst in the sclerotherapy of thyroid cysts.Methods A total of 200 patients with thyroid cysts,who were admitted to the Longyan Municipal First Hospital of China between August 2020 and August 2021,were enrolled in this study.The patients were randomly and equally divided into group zero(suctioning out all the amount of the injected lauromacrogol),and,according to the percentage of the retained lauromacrogol dosage to the total cystic fluid,group 10%,group 20%,group 30%and group 50%,with 40 patients in each group.Thyroid color ultrasound was reviewed at 1,3,6,and 12 months after treatment.The changes of capsule volume,curative efficacy,influencing factors,and adverse reactions after the cyst became sclerosis were analyzed.Logistic regression analysis was used to analyze the factors affecting the postoperative efficacy.Results In all the 5 groups,the suctioned fluid was dark red in colour,and the patients had cystic nodules.The preoperative mean cyst volume was(20.43±5.86)cm3.In all the 5 groups,the postoperative changes in cyst volume indicated that the postoperative one-month cyst volume significantly shrank when compared with the preoperative volume,the postoperative 3-month cyst volume remarkably shrank when compared with the postoperative one-month volume,and the postoperative 6-month cyst volume strikingly shrank when compared with the postoperative 3-month volume(all P＜0.05),while no statistically significant difference in the cyst volume existed between the postoperative 12-month value and the postoperative 6-month value(P＞0.05).The postoperative 6-month total effective rate of all the five groups was 87%(174/200),and no statistically significant differences in the postoperative 6-month curative effect existed between each other among the 5 groups(P＞0.05).Taking the postoperative 6-month curative effect as the dependent variable,and the age,sex,thick cystic wall,cystic septum,and preoperative cyst volume as independent variables,the binary logistic regression analysis was conducted,which revealed that the thick cystic wall(OR=0.24,95%CI=0.08-0.72,P=0.01)and the cystic septum(OR=0.21,95%CI=0.07-0.67,P=0.01)were the factors affecting the postoperative 6-month curative effect.The main side reaction was pain,which was tolerable by patients.There was no significant difference in the incidence of adverse reactions between each other among the five groups(all P＞0.05).Conclusion In treating thyroid cysts by using ultrasound-guided lauromacrogol sclerotherapy,there is no relationship between the curative effect and the percentage of the retained lauromacrogol dosage to the total cystic fluid.The best curative effect can be achieved at 6 months after injection of lauromacrogol,which can be used as the optimal time for follow-up check.The thick cystic wall and the cystic septum are the main factors that affect the curative effect of lauromacrogol sclerotherapy.For the treatment of thyroid cyst,lauromacrogol sclerotherapy carries reliable curative effect with few adverse reactions,therefore,this therapy is worthy of clinical application.(J Intervent Radiol,2024,32:69-73)

The mammalian target of rapamycin (mTOR) pathway is abnormally activated in lung cancer. However, the anti-lung cancer effect of mTOR inhibitors as monotherapy is modest. Here, we identified that ginsenoside Rh2, an active component of Panax ginseng C. A. Mey., enhanced the anti-cancer effect of the mTOR inhibitor everolimus both in vitro and in vivo. Moreover, ginsenoside Rh2 alleviated the hepatic fat accumulation caused by everolimus in xenograft nude mice models. The combination of everolimus and ginsenoside Rh2 (labeled Eve-Rh2) induced caspase-independent cell death and cytoplasmic vacuolation in lung cancer cells, indicating that Eve-Rh2 prevented tumor progression by triggering paraptosis. Eve-Rh2 up-regulated the expression of c-MYC in cancer cells as well as tumor tissues. The increased c-MYC mediated the accumulation of tribbles homolog 3 (TRIB3)/P62⁺ aggresomes and consequently triggered paraptosis, bypassing the classical c-MYC/MAX pathway. Our study offers a potential effective and safe strategy for the treatment of lung cancer. Moreover, we have identified a new mechanism of TRIB3/P62⁺ aggresomes-triggered paraptosis and revealed a unique function of c-MYC.

Acute pancreatitis (AP) is a severe disease with an increasing incidence rate in clinical practice. Although most patients have mild pancreatitis, the fatality rate of severe pancreatitis remains at a relatively high level, and therefore, early-stage, simple, and accurate clinical scoring systems are urgently needed to determine the severity of AP, so as to facilitate effective disease management and symptomatic treatment and reduce the fatality rate of patients. At present, a large number of studies have demonstrated that the scoring systems such as Ranson score, APACHE Ⅱ score, BISAP score, CTSI score, and some serological markers have been used to evaluate the severity and prognosis of AP, but all of them have certain limitations. This article reviews the research advances in the existing scoring systems, single serological markers, and related modified scoring systems in recent years. Through a literature review, it is concluded that there is no a single scoring system or a single indicator that can cover the whole process of AP diagnosis and treatment and accurately judge the severity of AP, and therefore, it is necessary to develop a new scoring system or combine various indicators for comprehensive evaluation.

Objective:To observe the effect of Jiuwei Chushi Decoction on sex hormone level of serum and Kisspeptin protein expression in hypothalamus of Central Precocious Puberty (CPP) rats model.Methods:After sixty female rat were breeded from SD rats, they are randomly divided into six groups, which are normal control group, model group, Gonadorelin group, and high, medium and low dose group of Jiuwei Chushi Decoction, 10 in each group. In addition to the normal control group, the other groups were subcutaneously injected with N-methyl-DL-aspartic acid to establish CPP model. Gonadorelin group was subcutaneously injected with Gonadorelin 100 μg/(kg·d), and high, medium and low dose group of Jiuwei Chushi Decoction were intragastrated with Jiuwei Chushi Decoction extract at 5.75, 2.87 and 1.43 ml/(kg·d) respectively. The levels of Luteinizing Hormone (LH), Follicle Stimulating Hormone (FSH),Estradiol (E 2) were detected by ELISA, and the protein expressions of Gonadotropin-releasing Hormone (GnRH) and Kisspeptin in hypothalamus were detected by Western Blot. Results:Compared with the model group, the levels of LH and E 2 of the low, medium and high dose group of Jiuwei Chushi Decoction were significantly decreased ( P<0.05), while the FSH level was significantly increased ( P<0.05). The relative protein expression of GnRH (0.657±0.110, 0.536±0.152 vs. 0.912±0.219) and Kisspeptin (0.508±0.035,0.347±0.073 vs. 0.659±0.030) in the medium and high dose group of Jiuwei Chushi Decoction was lower than that of model group. Conclusion:Jiuwei Chushi Decoction could affect hypothalamic Kisspeptin protein expression, inhibite hypothalamic GnRH expression, and decrease LH and E 2 levels in the serum of CPP rats.

External apical root resorption is among the most common risks of orthodontic treatment, and it cannot be completely avoided and predicted. Risk factors causing orthodontic root resorption can generally be divided into patient- and treatment-related factors. Root resorption that occurs during orthodontic treatment is usually detected by radiographical examination. Mild or moderate root absorption usually does no obvious harm, but close attention is required. When severe root resorption occurs, it is generally recommended to suspend the treatment for 3 months for the cementum to be restored. To unify the risk factors of orthodontic root resorption and its clinical suggestions, we summarized the theoretical knowledge and clinical experience of more than 20 authoritative experts in orthodontics and related fields in China. After discussion and summarization, this consensus was made to provide reference for orthodontic clinical practice.

Objective:To explore the effect of early pulmonary rehabilitation management model in elderly critically ill patients with mechanical ventilation.Methods:Using convenience sampling, 64 elderly critically ill patients with mechanical ventilation in the Intensive Care Unit (ICU) of the First People's Hospital of Hefei from June to December 2019 were selected as the control group, and 64 elderly critically ill patients with mechanical ventilation in the ICU of the First People's Hospital of Hefei from January to July 2020 were selected as the experimental group. The control group carried out routine nursing, and the experimental group implemented the early pulmonary rehabilitation management model on the basis of routine nursing. The pulmonary function indicators, invasive mechanical ventilation time, ICU stay and cost, delirium incidence, ventilator associated pneumonia (VAP) incidence, outcome and satisfaction of patients and their families were compared between the two groups.Results:The pulmonary function indicators of patients in the experimental group were better than those in the control group, and the difference was statistically significant ( P<0.01) . The invasive mechanical ventilation time and ICU stay of the experimental group were shorter than those of the control group, and the ICU cost was lower than that of the control group, and the differences were statistically significant ( P<0.01) . The incidence of delirium and VAP in the experimental group was lower than those in the control group, and the number of outcome cases was more than that in the control group, and the differences were statistically significant ( P<0.05) . The satisfaction of patients and their families in the experimental group was higher than that in the control group with a statistically significant difference ( P<0.05) . Conclusions:The implementation of the early pulmonary rehabilitation management model can effectively improve the pulmonary function of the elderly critically ill patients with mechanical ventilation, reduce the occurrence of complications and the patient's family financial burden, and increase the satisfaction of patients and their families, which is feasible and extendable.

Objective: The metaanalysis aims to estimate the prevalence of suicide plan among college students in mainland China, and to provide more clues and reference for control and prevention of suicide. Methods: The relevant studies were systematically searched via electronic databases (PubMed，Embase，CNKI，Wan Fang Data，VIP). We only selected original articles that either reported on Chinese retrieval words of "college students" "undergraduate" "university" "college" "colleges and universities" "suicide plans" "detection rate" "prevalence" "report rate", and the English retrieval words of "undergraduate" "college" "university" "suicide" "suicidality" "suicide plans" "suicidal plans suicide intending" "prevalence" "report rate" "detection rate" "China" "Chinese". And Stata 12.0 software was used to make a metaanalysis of the data. Results: A total of 18 eligible studies, with 47 071 college students, were finally included. The maximum and minimum reported prevalence of suicidal plan among college students in China mainland was 4.4%(95%CI: 3.4%-5.4%).Subgroup analyses showed that the pooled estimate of suicidal plan of boys(5.4%) was higher than girls’(4.2%); The prevalence among college students from earth, middle and west areas were 5.1%，2.7%，4.5%, respectively; The prevalence among college students in 2010 and after (4.4%)was higher than that before 2010(4.3%), The prevalence among college students of life time suicide plan (4.9%)was higher than that during the past 12 months(4.0%), but there was no statistical significance in the subgroup(P>0.05) . Sensitivity analysis suggested that the results of metaanalysis were relatively stable, while funnel plot analysis suggested that publication bias might exist. Conclusion Prevalence of suicidal plans among college students in mainland China is respectively low, and there was no statistical significance in gender, region, the period of time and simple size.

Objectives: To explore weather oxygen uptake efficiency slope (OUES) may predict the prognosis in patients with idiopathic pulmonary arterial hypertension (IPAH). Methods: The consecutive newly diagnosed IPAH patients in our hospital from 2010-11 to 2015-06 were prospectively enrolled and regular follow-up study was conducted to record cardiovascular events (death and lung transplantation). Kaplan–Meier curve, uni- and multivariate Cox regression analysis were performed to assess the survival rate in relevant patients. Results: A total of 210 IPAH patients at the mean age of (32±10) years were finished cardiopulmonary exercise test (CPET) and received regular follow-up study including 159 female. There were 31 patients died and 1 received lung transplantation over 41 months follow-up period. OUES was positively related to peak oxygen uptake (VO2)/body weight (r=0.71, P<0.0001). Multivariate analysis demonstrated that OUESI and NT-proBNP could independently predict the prognosis of IPAH patients. The 5-year survival rate in patients with OUESI≤0.52 L/(min?m2) was lower than those with OUESI>0.52 L/(min?m2) (41.9% vs 89.8%), P<0.0001.Conclusion: OUES as a submaximal CPET parameter may well predict the prognosis in IPAH patients.

A method of ultra performance liquid chromatography-quadrupole-time of flight-mass spectrometry ( UPLC-Q-TOF MS) was developed to determine 35 kinds of illegally added chemical fungicides in pesticide formulations. The samples were pretreated based on the ultrasonic extraction by the solvent of methanol, and then separated on a Zorbax C18(100 mm×1. 8 mm, 2. 1 μm) column by a gradient elution with 0. 1% formic acid aqueous solution and acetonitrile as the mobile phase. The mass spectrometer was operated under positive mode. Under the optimal conditions, the recoveries at three spiked levels (0. 2, 0. 4, and 2. 0 mg/kg) were in the range of 81. 0%-101. 3% and the RSDs were 1. 0%-4. 4%. Based on the developed method, 100 samples were analyzed, and among which 6 samples were screened out chemical fungicides. The proposed method was high-efficient, accurate and reliable for the qualitatively screening of illegaly added chemical fungicides.
