Objective:To explore the relationship between relapse tendency and psychological craving in fe-male methamphetamine(MA)-dependent young adults,focusing on the roles of self-control and future time per-spective.Methods:A total of 340 MA-dependent young adults from two women's compulsory isolation drug reha-bilitation centers in Sichuan Province were included.Participants were assessed with the Relapse Tendency Ques-tionnaire(RTQ),Obsessive Compulsive Drug Use Scale(OCDUS),Drug Abuser Self-Control Ability Question-naire(DASAQ)and General Future Time Perspective Scale(GFTPQ).The moderated mediation model was ana-lyzed by using the SPSS macro program PROCESS(version4.2).Results:The RTQ scores were positively correla-ted with the OCDUS scores(r=0.45,P＜0.001).The DASAQ scores partially mediated the relationship between the scores of OCDUS and RTQ,accounted for 37.91％of the total effect.The GFTP scores moderated the relation-ship between the scores of the OCDUS,DASAQ and RTQ(β=-0.18,0.19,P＜0.001).Conclusion:The influ-ence of psychological craving on relapse tendency in female MA-dependent young adults exhibits a moderated me-diating effect,suggesting the potential of enhancing self-control and future time perspective for preventing relapse and improving detoxification efficiency.

Objective To discuss the application of the"rotating guidewire and correcting the filter recovery hook direction technique"("rotation-correction loop technique"for short),a technique invented by the authors in clinical practice,in the retrieval of complex inferior vena cava filter(IVCF),and to discuss its technical skills and advantages.Methods The clinical data of 417 patients carrying an IVCF,who were admitted to the Department of Vascular Surgery of Second Hospital of Shanxi Medical University of China to retrieve IVCF between January 2022 and December 2022,were retrospectively analyzed.Taking the time spent on the retrieval of IVCF and the intraoperative radiation dose as the evaluation indicators,the advantages and disadvantages of the standard filter retrieval technique,the"rotation-correction loop technique"and the other loop-assisted techniques were compared.Results Both the intraoperative radiation dose and the time spent on the retrieval of IVCF using"rotation-correction loop technique"were remarkably lower than those of other loop-assisted techniques(P＜0.000 1).Conclusion For the retrieval of complex IVCF,especially for the IVCF which is heavily tilted and/or its recovered hook is attached to the vascular wall,the use of"rotation-correction loop technique"can shorten the time spent on the the retrieval of IVCF and reduce the intraoperative radiation dose.This technique carries high safety and practicability,the device is simple and it can be manipulated by single physician,which is conducive to clinical application and promotion.(J Intervent Radiol,2024,33:289-294)

In recent years, the corona virus disease 2019 (COVID-19) pandemic has had a huge impact on the global medical, political and economic fields. Since the beginning of the COVID-19 epidemic, our understanding of the impact of COVID-19 has grown exponentially. Recently, the COVID-19 epidemic has changed rapidly in China, and there has been controversy over how to carry out surgical operations for patients with lung neoplastic lesions. Some studies have shown that lung cancer patients undergoing surgery are more likely to experience respiratory failure and perioperative death after contracting COVID-19 than the general population, however, delays in cancer treatment are also associated with increased mortality among these patients. In particular, the novel coronavirus Omikron variant has a higher transmissibility and may escape the immunity obtained through the previous novel coronavirus infection and vaccination. In order to minimize the risk of novel coronavirus infection in surgical patients, it is necessary to develop new treatment guidelines, expert consensus and preventive measures. However, the current rapid change of the epidemic situation has led to insufficient time and evidence to develop guidelines and consensus. Therefore, thoracic surgeons need to evaluate specific patient populations at higher risk of severe complications before surgery and weigh the benefit of surgical treatment against the risk of novel coronavirus infection. We try to give some recommendations on lung surgery during the current domestic epidemic situation based on the guidelines and consensus of oncology and thoracic surgery organizations in different regions on lung surgery.

Objective:To explore the spatial and temporal distribution patterns of emerging snail-infested sites in different environmental types in Yunnan Province.Methods:The data of snail-infested sites in Yunnan Province from 1950 to 2014 (from Yunnan Institute for Endemic Diseases Control and Prevention), were collected and sorted out, a spatial and temporal database on the distribution of emerging snail-infested sites were established, and the changes in the spatial and temporal distribution of emerging snail-infested sites in different environments types (ditches, tangerines, paddy fields, dry land, beaches and other environments) were studied by using spatial autocorrelation analysis and scanning statistics analysis.Results:From 1950 to 2014, the annual number of emerging snail-infested sites in Yunnan Province reached a peak (1 730) in 1955 and then showed a fluctuating downward trend. From 1993 to 2014, the number of emerging snail-infested sites remained below 100, and increased to 160 and 131, respectively, in 2004 and 2013. The longest mean duration of 43.85 years was recorded for the beaches environment for emerging snail-infested sites, followed by the paddy fields environment with a mean duration of 37.01 years, and the shortest mean duration of 20.44 years for the tangerines environment. Spatial autocorrelation analysis showed that there was a positive spatial correlation between the duration of emerging snail-infested sites of different environmental types (global Moran's I ranged from 0.43 to 0.64, P < 0.05). Scanning statistics analysis showed that emerging snail-infested sites of different environmental types had spatial and temporal aggregation ( P < 0.001), with 3- 6 clusters of statistically significant aggregation detected respectively. Conclusion:The emerging snail-infested sites in different environments types in Yunnan Province have spatial and temporal aggregation, and it is necessary to strengthen monitoring and prevention and control of the aggregation areas of different environment types to prevent further spread of the snail.

Objective:To compare the efficacy, safety and total clinical benefit between urokinase and reteplase in catheter directed thrombolysis(CDT) of deep venous thrombosis(DVT) patients.Methods:The clinical data of 88 patients receiving IVC filter insertion and CDT in iliofemoral veins was retrospectively analyzed. Fifty-two patients received urokinase(UK), 36 received reteplase(rPA). The efficacy of thrombolysis were evaluated by thrombolytic rate , the change of limb circumferences. All the patients were followed up at the 3rd、6th and 12th month , Villalta score was used to estimate the severity of postthrombotic syndrome(PTS).Results:The thrombolytic rate in the UK group was 75.5% and 84.2% in the rPA( P<0.001); the change of limb circumferences in the UK group was 84.0%, vs. 90.0% in the rPA group( P<0.001); the Villalta score at the 3rd、6th and 12th month in the UK group were 3.03、3.63、4.57 respectively, while in the rPA group were 2.29、3.06、3.70 respectively( P<0.001) . The thrombolytic time and length of hospital stay in the rPA group is shorter than that in the UK′s. Conclusions:The thrombolytic efficacy of rPA is superior to UK. In addition, rPA can reduce the severity of PTS when compared with UK.

Objective To evaluate 3.0T high resolution magnetic resonance (HRMRI) scanner for determining the carotid plaque vulnerability.Method Fifteen inpatients with carotid plaque stenosis were enrolled.The stenosis rate confirmed by Doppler ultrasound was 50％-99％ (excluding those with 100％ occlusion of the carotid artery).Head and neck coil 24 (HNC 24) was used for extracranial carotid artery plaque scan.Results There was no statistically significant difference between pathology and 3.0T HRMRI in the detemination of carotid plaque composition (P =0.546)and carotid artery stenosis rate (P =0.289).HRMRI showed good consistency with pathology in detecting intraplaque hemorrhage (Kappa =0.816) and lipid necrosis core (Kappa =0.771),and normal consistency with pathology in detecting calcification (Kappa =0.674).The highest sensitivity (87.23％) and the highest specificity (97.77％) of intraplaque hemorrhage were detected for the core of lipid necrosis.Conclusion The 3.0T high resolution magnetic resonance detailed analysis of extracranial carotid plaque composition,morphology,luminal stenosis,plaque lumen and wall area data for assessment.

BACKGROUND: Venous thromboembolism (VTE) is a recognized complication in lung cancer patients with higher morbidity and mortality. The purpose of this study is to determine the incidence of lower extremity venous thrombosis (LEDVT) in lung cancer patients and to reveal the risk factors for LEDVT during admission in our center. METHODS: We first connected 231 patients with lung cancer admitted to the Department of Lung Cancer Surgery, Tianjin Medical University General Hospital from July 2017 to December 2017. All these patients underwent color ultrasound examination of lower extremity vein on admission to analyze the incidence of LEDVT. At the same time, the incidence of LEDVT in patients with benign lung diseases on admission was used as control. In order to explore the possible risk factors for LEDVT in these patients with lung cancer, we further analyze the correlations between LEDVT and their clinical features. At the same time, we also analyze the relationship between LEDVT and Plasma D-Dimmer, fibrinogen (FIB), thrombin time (TT), activated partial thrombin time (APTT), prothrombin time (PT) and platelet (PLT) in these patients with lung cancer. RESULTS: Among 231 patients with lung cancer, the incidence rate of LEDVT on admission was 5.2% (12/231), and in 77 patients with benign lung disease, there was none of patients with LEDVT on admission. This result indicated that the admitted incidence rate of LEDVT in patients with lung cancer was significantly higher than that in patients with benign lung disease (P<0.05). Further analysis in patients with lung cancer found that there was higher incidence rate of LEDVT in distant metastasis group (including N3 lymph node metastasis) compared to in non-distant metastasis group (11.29%, 7/62 vs 2.96%, 5/169) (P<0.05). In patients with lung cancer, the median value of D-Dimer in LEDVT group was 1,534 mg/L (369 mg/L-10,000 mg/L), which was significantly higher than that in the non-LEDVT group (539 mg/L, 126 mg/L-1,000 mg/L) (P<0.05). There was no statistically significant difference in FIB, TT, APTT, PT and PLT between these two groups (P>0.05). CONCLUSIONS The overall incidence of LEDVT in our central lung cancer patients was approximately 5%, significantly higher than that in patients with benign lung disease. Lung cancer patients with distant metastasis (including N3 lymph node metastasis) at admission were more likely to develop LEDVT, and these patients with higher D-Dimer values should be considered the possibility of VTE events.

Objective To explore the relationship between intermedin (IMD) and renal interstitial capillary loss in IgA nephropathy (IgAN) patients.Methods Renal biopsy specimens collected from primary IgAN patients in our hospital (n=80) were compared with normal renal tissues.Expressions of IMD,CD31 and VE-cadherin were examined by immunohistochemical method,and plasma concentrations of IMD and TGF-β1 in 37 cases from the 80 cases were compared.The relationship between IMD and renal interstitial capillary loss in IgAN patients was analyzed.Results IMD and VE-cadherin in renal tubule interstitium expressions increased compared to the control group at the early stage of IgAN (P ＜ 0.05).CD31 expression remained unchanged at the early stage of pathological lesions of IgAN (P ＞ 0.05),but decreased at the early stage of clinical stage of IgAN compared to the control (P ＜ 0.05).Expressions of IMD,CD31 and VE-cadherin were reducing as the disease progressed,and the correlations of CD31 and VE-cadherin (r=0.517,P ＜ 0.01),IMD and CD31(r=0.655,P ＜ 0.01) or IMD and VE-cadherin (r=0.576,P ＜ 0.01) were positive.Plasma concentrations of IMD and TGF-β1 were higher than those of the control group at the early stage of IgAN (P ＜ 0.05),and the changes of IMD and TGF-β1were correlated positively (r=0.582,P ＜ 0.01).Conclusion Compared with the control group,expression of IMD in kidney tubules increases at the early stage of IgAN,and change of IMD correlates closely with the renal interstitial capillary loss.Plasma concentrations of IMD and TGF-β1 increase compared with the control group at the early stage of IgAN,and the changes of IMD and TGF-β1 are related closely.

Objective To investigate the glomerular microvascular injury and repair in patients with IgA nephropathy (IgAN) as well as its relationship with intermedin (IMD).Methods Eighty cases of renal tissue taken from patients first diagnosed as IgAN in Shanxi Provincial People's Hospital Affiliated to Shanxi Medical University and 15 cases of normal renal tissue were detected by the expression of glomerular IMD,CD31,and VE-cadherin through immunohistochemical method.ELISA method was used to detect VEGF and IMD of plasm from 31 normal subjects and 36 cases chosen from the IgAN patients.Their changes and internal relationship were analyzed according to Lee's and chronic kidney disease (CKD) classification.Results (1) Compared with the control group the expressions of CD31,IMD,and VE-cadherin in IgAN patients were statistically significant (P ＜0.01).Compared with the control group the levels of IMD and VEGF in plasma of IgAN patients in early stage of CKD group and late stage of CKD group were statistically significant (P ＜ 0.01).(2)Correlation analysis:the expression of glomerular CD31 and Lee's classification were negatively correlated (r=-0.232,P ＜ 0.05);glomerular IMD was negatively correlated with Lee's classification (r=-0.241,P＜0.05),while positively correlated with glomerular VE-cadherin (r=0.417,P＜ 0.01).VEGF in plasma of IgAN patients was positive correlated with CKD classification,BUN (r=0.458,0.409,P＜0.05),and negatively correlated with serum ALB (r=-0.532,P＜0.01).Conclusion Microvascular injury exists in patients with IgAN.The expression of VE-cadherin and IMD are positively correlated,suggesting that IMD may be involved in the progression of vascular protection and angiogenesis in IgAN.The contents of IMD and VEGF in plasma of IgAN patients increase,indicating that they may play a role in the progression of IgAN.
