Objective To investigate the effect of comprehensive psychological intervention on cooperation degree with intravenous infusion of preschool children. Methods 240 children patients with intravenous infusion were divided into the observation group and the control group with 120 cases in each group.Children patients in two groups were all given venipuncture by two nurses who had more than 5 years of working experience,skilled venipuncture technique and were good at doing mental work for children.The control group was given intravenous infusion directly after venipuncture without giving any psychological intervention.The observation group was given comprehensive psychological intervention before venipuncture.The different psychological behavioral reactions during the venipuncture were evaluated.The cooperation degree and the first-time success rate of venipuncture for the two groups were taken for statistics. Results The psychological behavioral reactions of the observation group were as followed:the active type was 51.67％,the tension type was 30.83％,and 7.50％ for the type of fear,the compulsive type was 10.00％.Compared with the control group,the difference was significant.The cooperation degree with intravenous infusion was 82.50％,the difference was significant compared with the control group.The first-time success rate in the observation group was 86.67％,higher than 75.83％ in the control group. Conclusions Psychological interventions according to the behavior and psychological reaction of preschool children with intravenous infusion can alleviate the negative emotions and improve the cooperation degree of preschool children.

Objective To investigate the risk factors of upper gastrointestinal injury induced by non-steroidal anti-inflammatory drugs (NSAIDs).Methods A total of 1032 patients which used NSAIDs was selected.Patients were divided into two groups based on the condition of dyspepsia,peptic ulcer or upper gastrointestinal bleeding:the adverse drug reaction group (331 cases) and the control group (701 cases).Data of two groups on clinical presentation,laboratory test,medication and treatment were analyzed.Risk factors for the adverse drug reaction were identified by multivariable Logistic regression.Results The two groups had significant difference in age ＞ 65 years old,Helicobacter pylori (Hp) infection,ulcer history,drug overdose,combination with glucocorticoid,addicted to tobacco and alcohol history,non-specific inhibitor of cyclooxygenase(COX)-2,combination with anticoagulant,concomitant chronic cardiopulmonary disease (P ＜ 0.05).Logistic regression analysis by backward elimination method revealed that following variables retained,such as combination with glucocorticoid (OR =3.104,95％ CI 1.936-4.695),Hp infection (OR =2.768,95％ CI 2.047-3.742),drug overdose (OR =2.411,95％ CI 1.683-3.453),ulcer history (OR =1.781,95％ CI 1.278-2.480),age ＞ 65 years old (OR =1.659,95％ CI 1.237-2.225),non-specific inhibitor of COX-2 (OR =1.470,95％ CI 1.103-2.133),addicted to tobacco and alcohol history (OR =1.459,95％ CI 1.032-2.064),concomitant chronic cardiopulmonary disease (OR =1.357,95％ CI 1.008-2.143),P＜0.05.Conclusion Combination with glucocorticoid,Hp infection,drug overdose,ulcer history,age ＞ 65 years old,non-specific inhibitor of COX-2,addicted to tobacco and alcohol history,concomitant chronic cardiopulmonary disease are risk factors of upper gastrointestinal injury induced bv NSAIDs.

Objective To explore the clinical manifestations of hypermastigote detected from bronchoalveolar lavage fluid in children with mycoplasma pneumoniae pneumonia (MPP).Methods The clinical data from 18 cases (7 male cases,11 female cases;the age raged from 5 months to 13 years;13 case lived in rural cottage,5 cases lived in town building;the course ranged from 2 to 60 days) of MPP coinfected with hypermastigote were retrospectively analyzed,including the symptomatic and physical examination data, laboratory test, chest imaging features, bronchoscopic manifestation imaging,treatment and prognosis.The clinical characteristics and treatment of MPP coinfected with hypermastigote were analyzed.Results Clinical symptoms showed that 18 cases had cough, 14 cases had fever and 4 cases had asthma;laboratory blood routine test detected that 13 cases had increased leukocytes,5 cases with increased eosinophils;11 cases with increased C reactive protein and 8 cases with increased erythrocyte sedimentation rate.Eleven of 18 cases received immunological examination,which showed that 3 cases had increased IgG,2 cases with increased IgM,5 cases with increased IgA,and 11 cases with decreased ratio of CD4 and CD8;bronchoalveolar lavage fluid test showed that 1 case had increased eosinophils and hypermastigote were detected in 18 cases.High density spotty shadow were seen in chest imaging.Mucosal congestion, attached with white sputamentum, longitudinal folds, floc floating and sputum bolt obstructing within the lumen were seen under the bronchoscopy.The macrolides antibiotics combined with metronidazole (5 cases received metronidazole lung lavage) were effective.Conclusions Hypermastigote is a new type pathogen isolated from the lower respiratory tract in Liaocheng.For patients with MPP who have unsatisfactory response, hypermastigote should be taken into account and combined with metronidazole in therapy for better effect.

Objective:To investigate the value of serum soluble programmed cell death protein 1 (sPD-1), soluble B7 homolog 5 (sB7-H5) and trefoil factor 2 (TFF2) in evaluating the severity of disease and the risk of death in patients with acute pancreatitis (AP).Methods:A prospective research method was adopted. Three hundred and twenty-eight patients with AP (AP group) from February 2020 to February 2021 in Xiangyang Central Hospital were selected, including 124 patients with mild AP (MAP), 106 patients with moderately severe AP (MSAP) and 98 patients with severe AP (SAP). The serum levels of sPD-1, sB7-H5 and TFF2 were measured by enzyme-linked immunosorbent assay and compared with 60 healthy people (healthy control group). The patients with AP were followed up for 90 d, 284 patients survived and 44 died. The amylase, C-reactive protein (CRP), procalcitonin (PCT), acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), sequential organ failure assessment (SOFA), modified CT severity index (MCTSI), sPD-1, sB7-H5 and TFF2 were compared between the two groups. Pearson method was used for correlation analysis. Multivariate Logistic regression was used to analyze the independent risk factors of death in patients with AP. The efficacy of sPD-1, sB7-H5 and TFF2 in predicting the death in patients with AP was evaluated using the receiver operating characteristics (ROC) curve.Results:The sPD-1, sB7-H5 and TFF2 in AP group were significantly higher than those in healthy control group: (177.99 ± 17.81) ng/L vs. (50.20 ± 10.81) ng/L, (2.69 ± 0.72) μg/L vs. (1.40 ± 0.35) μg/L and (569.97 ± 38.91) μg/L vs. (94.59 ± 11.98) μg/L, and there were statistical differences ( P<0.01). The amylase, sPD-1, sB7-H5 and TFF2 in patients with MSAP and SAP were significantly higher than those in patients with MAP: (639.36 ± 91.67) and (835.24 ± 109.30) U/L vs. (575.24 ± 89.78) U/L, (180.13 ± 20.61) and (221.17 ± 15.70) ng/L vs. (142.03 ± 16.76) ng/L, (2.85 ± 0.74) and (3.34 ± 0.82) μg/L vs. (2.05 ± 0.52) μg/L, (539.66 ± 36.58) and (763.55 ± 40.08) μg/L vs. (442.90 ± 35.79) μg/L, the indexes in patients with SAP were significantly higher than those in patients with MSAP, and there were statistical differences ( P<0.01). Pearson correlation analysis result showed that sPD-1 was positively correlated with sB7-H5 and TFF2 in patients with AP ( r = 0.552 and 0.641, P<0.01), and the sB7-H5 was positively correlated with TFF2 ( r = 0.610, P<0.01). The amylase, CRP, PCT, APACHE Ⅱ, SOFA, MCTSI, sPD-1, sB7-H5 and TFF2 in the dead patients were significantly higher than those in the living patients: (1 098 ± 105) U/L vs. (641 ± 93) U/L, (235.60 ± 40.17) mg/L vs. (118.04 ± 32.90) mg/L, (4.32 ± 0.52) μg/L vs. (3.14 ± 0.44) μg/L, (19.39 ± 3.14) scores vs. (11.18 ± 2.53) scores, (12.13 ± 2.78) scores vs. (7.40 ± 2.15) scores, (7.12 ± 1.73) scores vs. (4.31 ± 1.52) scores, (222.23 ± 22.30) ng/L vs. (171.14 ± 18.50) ng/L, (3.37 ± 0.89) μg/L vs. (2.59 ± 0.59) μg/L and (629.27 ± 39.63) μg/L vs. (560.78 ± 30.45) μg/L, and there were statistical differences ( P<0.01). Multivariate Logistic regression analysis result showed that CRP, PCT, APACHE Ⅱ, SOFA, sPD-1, sB7-H5 and TFF2 were independent risk factors death of in patients with AP ( OR = 1.339, 1.416, 1.285, 1.327, 1.092, 1.171 and 1.080; 95% CI 1.145 to 1.566, 1.146 to 1.751, 1.132 to 1.460, 1.150 to 1.531, 1.024 to 1.164, 1.072 to 1.280 and 1.031 to 1.131; P<0.01). The ROC curve analysis result showed that the area under the curve of sPD-1, sB7-H5 and TFF2 combined detection to predict the death in patients with AP was larger than that of sPD-1, sB7-H5, and TFF2 alone detection (0.870 vs. 0.771, 0.734 and 0.685). Conclusions:The increase of serum sPD-1, sB7-H5 and TFF2 levels in patients with AP is related to the severity of disease of patients with AP. The combined detection of the indexes can assist in evaluating the risk of death in patients with AP.

Objective To investigate the clinical characteristics of metabolically healthy obese ( MHO) individuals, and to explore the risk of progression into metabolic disorders after 3 years. Methods A total of 3943 residents in Jining City were evaluated twice from February 2012 to August 2015, and 3766 individuals were enrolled excluding those with missing data. Of the subjects, 875 subjects were screened as metabolic normal population, which were divided into MHO(n = 127), metabolically healthy overweight (MHOW, n = 386), and metabolically healthy normal weight ( MHNW, n = 362) groups. T test, x2 test, and logistic regression analysis were used for data analysis. Results The incidence of MHO was 11. 63％ (127 / 1092) in obesity, and the proportion of MHO in females was higher than that in males(13. 91％ vs 7. 82％ , P<0. 05). Compared with MHNW group, the levels of HbA1C , fasting insulin, low density lipoprotein-cholesterol ( LDL-C), triglyceride ( TG), glutamyl transpeptidase (GGT), systolic blood pressure(SBP), diastolic blood pressure(DBP), and waist circumference(WC) were higher in MHO while glomerular filtration rate (GFR) and high density lipoprotein-cholesterol (HDL-C) were lower(all P<0. 05); and fasting insulin, LDL-C, TG, GGT, SBP, WC were higher in MHOW while HDL-C was lower (all P<0. 05). The levels of fasting insulin, TG, SBP, WC were higher in MHO while GFR and HDL-C were lower compared with MHOW(all P<0. 05). Following up for 3 years, the incidences of dyslipidemia in MHNW, MHOW, and MHO were 17. 96％ (65 / 362), 32. 90％ (127 / 386), 42. 52％ (54 / 127), respectively, with significant difference among three groups(P<0. 05). The incidences of hyperglycemia in the three groups were 20. 17％ (73 / 362), 22. 80％(88 / 386), 26. 77％ (34 / 127), respectively, without significant difference among groups ( all P > 0. 05). After adjustment for some factors including sex, age, fasting insulin, glutamic pyruvic transaminase, glutamic oxaloacetic transaminase, GGT, and creatinine, the risks of dyslipidemia in MHO ( OR = 2. 193, 95％ CI 1. 359-3. 539, P<0. 05) and MHOW(OR= 1. 705, 95％ CI 1. 190-2. 443, P<0. 05) were significantly increased as compared with MHNW. Conclusion Compared with MHNW individuals, MHOW/ MHO individuals show an obviously different clinical feature as well as with higher risks of dyslipidemia after 3 years.

BACKGROUND:Wogonin is a flavonoid extracted from the root of Scutellaria baicalensis.Previous studies have shown that baicalein has protective effects against cerebral ischemia-reperfusion injury,and can also reduce blood sugar and complications in diabetic mice,but its role and mechanism in diabetic cerebral infarction remain unclear. OBJECTIVE:To explore the effect of wogonin on nerve injury in rats with diabetic cerebral infarction and its mechanism. METHODS:Sprague-Dawley rats were randomly divided into six groups:control group,model group,low-dose wogonin group,medium-dose wogonin group,high-dose wogonin group,and high-dose wogonin+Ras homolog gene family member A(RhoA)activator group.Except for the control group,the other rats were established with diabetes and cerebral ischemia models using intraperitoneal injection of streptozotocin and middle cerebral artery occlusion.Low,medium-and high-dose wogonin groups were intragastrically given 10,20,40 mg/kg wogonin,respectively;high-dose wogonin+RhoA activator group was intragastrically given 40 mg/kg wogonin and intraperitoneally injected 10 mg/kg lysophosphatidic acid;control group and model group were given the same amount of normal saline once a day for 7 consecutive days.Rats in each group were evaluated for neurological deficits and their blood glucose levels were measured after the last dose.TTC staining was applied to detect the volume of cerebral infarction.Hematoxylin-eosin staining was applied to observe pathological changes in brain tissue.ELISA kit was applied to detect tumor necrosis factor-α,interleukin-6,malondialdehyde,and superoxide dismutase levels in brain tissue.Western blot was applied to detect the protein expression of RhoA and Rho-associated protein kinase(ROCK)2 in brain tissue. RESULTS AND CONCLUSION:Compared with the control group,the neuronal structure of rats in the model group was severely damaged,with cell necrosis and degeneration,the neurological deficit score,blood glucose level,and infarct volume were significantly elevated(P<0.05),the levels of tumor necrosis factor-α,interleukin-6,and malondialdehyde,and the protein expression of RhoA and ROCK2 in brain tissue were significantly increased(P<0.05),and the superoxide dismutase level was decreased(P<0.05).Compared with the model group,the low-,medium-,and high-dose wogonin groups showed improved neuronal damage,reduced cell degeneration and necrosis,a significant reduction in neurological deficit score,blood glucose level,infarct volume,and the levels of tumor necrosis factor-α,interleukin-6,and malondialdehyde,and the protein expression of RhoA and ROCK2 in brain tissue,and an increase in the superoxide dismutase level(P<0.05).Compared with the high-dose wogonin group,the high-dose wogonin+RhoA activator group significantly weakened the improvement in the above indexes of rats with diabetic cerebral infarction(P<0.05).To conclude,wogonin can improve the blood glucose level in rats with diabetic cerebral infarction,reduce cerebral infarction and nerve injury,and its mechanism may be related to the inhibition of RhoA/ROCK signaling pathway.

Objective:To establish a model C-GALAD for detecting hepatocellular carcinoma (HCC) from the chronic liver disease and healthy people based on the serum markers.Methods:A clinical cohort including 229 hepatocellular carcinoma patients, 2 317 patients with chronic liver disease and 982 healthy people, was retrospectively collected from eight hospitals or physical examination institutions from April 2018 to October 2020. The data were divided into a training set and a testing set by stratified sampling with a 6∶4 ratio. A predictive model was established on the training set using a logistic backward regression method and validated on the testing set. In addition, clinical data from March to July 2021 in Beijing You′ an Hospital affiliated to Capital Medical University, including 84 patients with liver cancer and 204 patients with chronic liver disease collected were used for external independent validation of the model. The receiver operating characteristic curve (ROC) area under curve (AUC), the sensitivity and the specificity were used to evaluate the effectiveness of the model.Results:Through the logistic backward regression method, the seven signatures including age, gender, alpha-fetoprotein (AFP), alpha-fetoprotein alloplasm-3 ratio (AFP-L3%), des-gamma-carboxyprothrombin(DCP), platelet (PLT) and total bilirubin (TBIL) were selected as risk factors in the detection model. The area under the ROC curve (AUC) of the model on the testing set was 0.954, with an 88.04% sensitivity and a 94.85% specificity, and the AUC of model on the external independent validation set was 0.943, with an 89.29% sensitivity and a 90.2% specificity, which were better than other published models.Conclusion:The C-GALAD Ⅱ model can accurately predict the risk of hepatocellular carcinoma occurrence, and thus provide a trustworthy diagnosis method of hepatocellular carcinoma.

Objective:To analyze the influencing factors of short-term efficacy of 125I seed implantation for recurrent cervical metastatic lymph nodes of esophageal squamous cell carcinoma after external beam radiation therapy (RESCC). Methods:From January 2013 to March 2019, 47 patients (42 males, 5 females; age: 47-77 years) with RESCC who underwent CT guided 125I seed implantation in Hebei General Hospital were retrospectively analyzed. Patients were divided into effective group (complete remission (CR)+ partial remission (PR)) and ineffective group (stable disease (SD)+ progressive disease (PD)) according to response evaluation criteria in solid tumors (RECIST) at 3 months after implantation. Multivariate logistic regression was used to analyze the independent influencing factors of short-term efficacy. Cut-off values were determined by ROC curve. Results:Of 47 patients, 26 were effective (3 were CR and 23 were PR) and 21 were ineffective (7 were SD, 14 were PD). Multivariate regression analysis showed that tumor diameter, immediate postoperative dose delivered to 90% gross tumor volume ( D90), recurrence interval time were independent influencing factors of short-term efficacy (odds ratio ( OR; 95% CI): 4.240(1.220-14.737), 0.999(0.999-1.000), 0.989(0.979-1.000), Wald values: 5.163, 5.043, 3.956, all P<0.05). ROC curve showed that the AUC of tumor diameter, D90 and recurrence interval time were 0.782, 0.786 and 0.838 respectively, with cut-off values of 4.85 cm, 115.78 Gy and 297.5 d respectively. Conclusions:The short-term efficacy of 125I seed implantation for RESCC is mainly related to the tumor diameter, immediate postoperative D90 and recurrence interval time. Patients with tumor diameter <4.85 cm, immediate postoperative D90>115.78 Gy and recurrence interval time >297.5 d have better efficacy.

Tung tree (Vernicia fordii) is an economically important woody oil plant that produces tung oil rich in eleostearic acid. Here, we report a high-quality chromosome-scale genome sequence of tung tree. The genome sequence was assembled by combining Illumina short reads, Pacific Bio-sciences single-molecule real-time long reads, and Hi-C sequencing data. The size of tung tree gen-ome is 1.12 Gb, with 28,422 predicted genes and over 73％ repeat sequences. The V. fordii underwent an ancient genome triplication event shared by core eudicots but no further whole-genome duplication in the subsequent ca. 34.55 million years of evolutionary history of the tung tree lineage. Insertion time analysis revealed that repeat-driven genome expansion might have arisen as a result of long-standing long terminal repeat retrotransposon bursts and lack of efficient DNA deletion mechanisms. The genome harbors 88 resistance genes encoding nucleotide-binding sites;17 of these genes may be involved in early-infection stage of Fusarium wilt resistance. Further, 651 oil-related genes were identified, 88 of which are predicted to be directly involved in tung oil biosynthesis. Relatively few phosphoenolpyruvate carboxykinase genes, and synergistic effectsbetween transcription factors and oil biosynthesis-related genes might contribute to the high oil content of tung seed. The tung tree genome constitutes a valuable resource for understanding genome evolution, as well as for molecular breeding and genetic improvements for oil production.
