Objective:To investigate the incidence of venous thromboembolism (VTE) in patients with esophageal cancer (EC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 8 458 EC patients who were admitted to Sichuan Cancer Hospital from January 2017 to December 2021 were collected. There were 6 923 males and 1 535 females, aged (64±9)years. There were 3 187 patients undergoing surgical treatment, and 5 271 cases undergoing non-surgical treatment. Observation indicators: (1) incidence of VTE in EC patients; (2) treatment and outcomes of patients with VTE. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the nonparameter rank sum test. Count data were expressed as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test or Fisher exact probability. Comparison of ordinal data was analyzed using the nonparameter rank sum test. Results:(1) Incidence of VTE in EC patients. Of 8 458 EC patients, 175 cases developed VTE, with an incidence rate of 2.069%(175/8 458). Among 175 VTE patients, there were 164 cases of deep venous thrombosis (DVT), 4 cases of pulmonary embolism (PE), 7 cases of DVT and PE. There were 59 surgical patients and 116 non-surgical patients. There was no significant difference in thrombus type between surgical and non-surgical EC patients with VTE ( χ2=1.95, P>0.05). Of 3 187 surgical patients, the incidence of VTE was 1.851%(59/3 187), including an incidence of 0.157%(5/3 187) of PE. PE accounted for 8.475%(5/59) of surgical patients with VTE. Of 5 271 non-surgical patients, the incidence of VTE was 2.201%(116/5 271), including an incidence of 0.114%(6/5 271) of PE. PE accounted for 5.172%(6/116) of non-surgical patients with VTE. There was no significant difference in the incidence of VTE or PE between surgical patients and non-surgical patients ( χ2=1.20, 0.05, P>0.05). (2) Treatment and outcomes of patients with VTE. Among 175 EC patients with VTE, 163 cases underwent drug treatment, and 12 cases did not receive treatment. Among 163 cases with drug therapy, 158 cases underwent anticoagulant therapy, 5 cases were treated with thrombolysis. All the 163 patients were improved and discharged from hospital. Conclusions:The incidence of VTE in patients with EC is relatively low, as 2.069%. There is no significant difference in the incidence of VTE or thrombus type between surgical EC patients and non-surgical EC patients.

Objective To assess the predictive effect of myocardial injury biomarkers (proBNP, CK-MB, and cTnI) on the severity of acute pancreatitis (AP). Methods The records of 246 patients diagnosed with acute pancreatitis who were treated at Ruijin Hospital Emergency Department from January 2015 to December 2016 were retrospectively analyzed. According to the revised 2012 Atlanta guidelines, these patients were divided into the mild acute pancreatitis (MAP, n=47), moderately severe acute pancreatitis (MSAP, n=151) and severe acute pancreatitis (SAP, n=48) groups. The highest plasma levels of troponin I (cTnI), creatine kinase (CK)-MB, N-terminal B-type brain natriuretic peptide (NT-proBNP), C-reactive protein (CRP), and procalcitonin (PCT) were recorded for comparison within 72 h after admission. The acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ ) score, sequential organ failure assessment (SOFA), bedside index for severity in acute pancreatitis (BISAP) and Balthazar computed tomography severity index (CTSI) were calculated at admission within 72 h. Whether there is an occurrence of organ dysfunction, and the organ types and persist time of organ dysfunction were recorded. The analysis of variance, SNK-q test and paired samples t test were used for the statistical analysis. Results The levels of proBNP, CK-MB, and cTnI were significantly higher in the SAP group than in the non-SAP group. The receiver operating characteristic (ROC) curve demonstrated cTnI had the maximum predictive power (AUC=0.872), while proBNP had the least predictive ability (AUC=0.763). The established model, which is to explore whether the myocardial injury markers had the predictive value, showed that the combination of myocardial injury indicators (CK-MB, cTnI) and traditional indicators had higher predictive value for SAP than traditional indicators alone (AUC=0.966 vs. AUC=0.945, P=0.04). Conclusions The elevated markers of myocardial injury had certain predictive value for severe acute pancreatitis.

BACKGROUND: The complicated localization of intramedullary nails and osteotomy more dependent on surgeons' experience limit the application of conventional total knee arthroplasty (TKA). The occurrence of three-dimensional (3D) printing technology can achieve precise localization and osteotomy in TKA.OBJECTIVE: To explore the effectiveness of 3D printing technology-aided TKA versus conventional TKA for genu varum.METHODS: Thirty-four patients with genu varum undergoing primary unilateral TKA were recruited and were then divided into two groups (n=17 per group) in accordance with the random number table. One group was treated with TKA with 3D printing guild plate (3D printing group), while the other group received the conventional TKA (conventional group).The intraoperative and postoperative blood loss, operation time, as well as the Hospital for Special Surgery score, range of motion, and lower limb mechanical alignment at 2 weeks postoperatively were compared between two groups.RESULTS AND CONCLUSION: (1) The range of motion of knee in the 3D printing group was larger than that in the conventional group, but had no significant difference at 2 weeks postoperatively (P=0.744). (2) There was no significant difference in the Hospital for Special Surgery scores between two groups at 2 weeks postoperatively (P= 0.532). (3) The postoperative lower limb mechanical alignment showed no significant difference between two groups (t=0.218, P=0.632).(4) The operation time in the 3D printing group was significantly shorter than that in the conventional group (P=0.000). (5) The blood loss in the 3D printing group was significantly less than that in the conventional group (P=0.000). (6) Our findings indicate that 3D printing technology-aided TKA exhibits similar results to the conventional TKA in the Hospital for Special Surgery scores, range of motion, and lower limb mechanical alignment, but it shortens the operation time,reduces the blood loss, and achieves precise osteotomy, which is available for the elderly with poor basic condition, and weak tolerance of surgery.

AIM:To observe the effects of cholecystokinin octapeptide (CCK-8) and its receptor antagonists on cAMP response element binding protein ( CREB) and phosphorylated CREB ( pCREB) expression in frontal cortex and hippocampus of morphine withdrawal rats , which aim to explore the post-receptor mechanism through which CCK-8 regu-lates morphine withdrawal .METHODS: After the morphine dependence and naloxone-precipitated withdrawal animal models were established, the effects of CCK-8, L-364718 (CCK1 receptor antagonist) and LY-288513 (CCK2 receptor an-tagonist) pretreatment on CREB and pCREB expression in frontal cortex and hippocampus were observed by Western blot -ting and immunohistochemistry .RESULTS:In rat frontal cortex neuron , CREB was expressed in both cytoplasm and nu-cleus, but pCREB was only highly expressed in the nucleus .In the pyramidal cell layer of hippocampal CA 1 region, CREB showed high expression in the cytoplasm and low expression in the nucleus , while pCREB was only expressed in the nu-cleus.No obvious change of CREB was observed after either chronic morphine treatment or naloxone withdrawal .The pCREB expression was increased after chronic morphine treatment and further increased after naloxone withdrawal .Com-pared with the withdrawal group , chronic pretreatment with CCK-8, L-364718 and LY-288513 had no effect on CREB expression in the frontal cortex , but obviously decreased the pCREB expression .In the hippocampus , pretreatment with L-364718 and LY-288513 decreased CREB and pCREB expression , but only the pCREB expression was decreased after CCK-8 treatment.CONCLUSION:CCK-8 and CCK receptor antagonists may alleviate morphine withdrawal symptoms by regulating CREB , with specificity in different brain regions .

BACKGROUND:Establishing a characteristic.stable and repeatable model of Th1/Th2 imbalance in animals,is the key of studying the mechanism of Th1/Th2 imbalance.OBJECTIVE:To observe the characteristics of Th1/Th2 imbalance in splenocytes derived from Balb/C mice immnnized by keyhole limpet hemocyanin(KLH).DESIGN:A randomized control exploratory experiment.SETTING:Hebei Provincial Forensic Laboratory.Institute of Basic Medicine,Hebei Medical University.MATERLALS:The experiment was carried out in the Hebei Provincial Forensic Laboratory,Institute of Basic Medicine,Hebei Medical University from September 2005 to January 2007.Balb/C mice were adopted in this study.and all the disposals were in accordance with the guidance of animal ethics.METHODS:Balb/C mice were immunized with KLH emulsified in complete Freund's adjuvant(CFA),splenocytes were acquired,and the peak of cytokine secretion was determined in 3 groups:KLH groups of 6.25 mg,kg.12.5 mg,kg and 25 mg/kg.According to the immunizing dose and immunizing frequency.mice were divided into 7 groups:KLH groups of 6.25 mg/kg,12.5 mg/kg and 25 mg/kg,secondary immunity groups of 6.25 mg/kg,12.5 mg/kg and 25 mg/kg,as well as control group.According to the determined levels of IgG1 and IgG2a in blood serum.mice were divided into KLH group of 6.25 mg/kg and control group.MAIN OUTCOME MEASURES:Mice splenocytes supematant was detected with enzyme linked immunosorbent assay (ELISA)for the production of Th1 cytokines interferon (IFN)-γ,interleukin(IL)-2.IL-12 p40 and Th2 cytokines IL-4 and IL-5.The levels of Th1 antibody IgG2a and Th2 antibody IgG1 in blood serum were also detected by ELISA.RESULTS:The spleen derived from KLH-immunized mice appeared hypertrophy,and the number of splenocytes was manifold.Splenocytes restimulated with KLH in vitro produced much more IFN-γ,IL-2,IL-4,IL-5,but not IL-12p40.IL-2 secretion was obviously elevated after incubated for 24 hours and achieved pinnacle at 48 hours;productions of IL-4,IL-5 and IFN-γ were elevated after 24 hours,and increased gradually to 96 hours;IL-12p40 production was very low at every time point.Using different doses of KLH inlmunity once or twice,could all lead to the elevated productions of IL-2,IL-4,IL-5,IFN-γ,and the elevation of IL-4/IFN-γ ratio,but the secondary immunity group of 6.25 mg/kg KLH showed obviously higher levels than other groups(P＜0.01).The level of KLH specific antibody IgG2a and IgG1,especially IgG1 was elevated in blood serum of KLH-immunized mice.CONCLUSION:Balb/C mice immunizad with KLH emulsified in CFA can indce a Th2 predominant imbalance in splenocytes.

Aim To investigate the effects and mechanisms of CCK-8 on IL-1? induced proliferation of RSC-364, a rat fibroblast-like synovial cell line. Methods MTT colorimetric assay and Western blot were used to measure cell proliferation and p38MAPK phosphorylation level to elucidate the mechanism of CCK-8 in IL-1? induced RSC-364 proliferation. Results CCK-8 significantly inhibited IL-1?-induced RSC-364 proliferation at 10 -12 , 10 -10 , 10 -8 , 10 -6 mol ? L -1 , and IL-1?-activated p38MAPK activity at 10 -10 , 10 -8 , 10 -6 mol?L -1 in a dose-dependent manner. The effect of CCK-8 was blocked by CR1409 (a CCKA-receptor antagonist) and CR2945 (a CCKB-receptor antagonist). Conclusion CCK-8 inhibits IL-1?-induced RSC-364 proliferation, probably by reducing p38MAPK activity through CCKA and CCKB receptors.

Forensic toxicology is a specialized subject which forensic medical appraisers and students must learn and master. As a new teaching mode,problem based learning method is attrcting a lot of attention. Applying "case" based PBL teaching method is an important method to train innovative and high technical ability forensic talents.

In view of the challenges and opportunities presented in the new century and after rational deliberations on five occasions, the completely new model of "hi tech+humanistic solicitude=the green hospital" was put forward and the overall framework of "one line of thought", "two cornerstones", and "three goals" was carefully formulated. In the meantime, all staff members of the hospital were called on to be involved in the "six major activities". As a result, great changes have taken place in the appearance and development of the hospital. It has been proved through practice that "the green hospital" is a successful model conforming to the trends of the times.

Aim To investigate the effects of cholecystokinin-octopeptide on IL-12 secreted in murine bone marrow-derived dendritic cells induced by lipopolysaccharide.Methods The CCK receptor subtypes were investigated by immunofluorescence in murine bone marrow-derived dendritic cells.Enzyme linked immunosorbent assay and Western blot were used to estimate the contents of IL-12 and p38MAPK activity.Results CCK-1R and CCK-2R were detected in BM-DC;CCK-8(at concentrations of 10-10,10-8,10-6 mol?L-1)could significantly increase the secretion of IL-12 in the LPS-induced DC, and LPS-activated p38MAPK activity in a dose-dependent manner.The effect of CCK-8 was reduced partially by CR1409(a CCK-1R antagonist) and CR2945(a CCK-2R antagonist).Conclusion CCK-8 could dose-dependently increase the expressions of IL-12 in LPS-induced DC,probably by promoting p38MAPK activity and the effect was mediated by CCK1 and CCK2 receptors.
