Globally, dengue fever is experiencing a gradual expansion in epidemiological scope, with high infection rates and significant adverse impacts on human health. Dengue fever in China remains predominantly an imported disease and/or a local transmission disease from imported cases, and there is no evidence yet that it has become endemic. Changes in vector distribution, climate changes, and population mobility were reported to correlate with dengue fever epidemic. The most key measure for preventing and controlling dengue fever is to cut off transmission route through comprehensive environmental management, control of mosquito vectors, and elimination of mosquito breeding sites. Dengue fever is an environmental and community disease, and the concept of "One Health" should be adopted, requiring government leadership, multi-sectoral cooperation, and mobilization of the whole society, with everyone participating in the elimination of breeding sites. Prevention and control of dengue fever are feasible, but remain "an uphill battle".

Objective:To explore the effect of multiple integration correction training for articulation disorder in children with functional alalia disorders (FAD) .Methods:From January 2020 to June 2021, 68 children with FAD who received language function training in the Affiliated Huaian First People 's Hospital of Nanjing Medical University were selected by convenience sampling. The children were divided into control group and observation group with the method of random number table, 34 cases each. The control group received routine speech training, while the observation group received multiple integration correction training for articulation disorder on the basis of the control group. The motor function of articulation organs, articulation syllable assessment results and speech function recovery were compared between the two groups before intervention (T1) , three months after intervention (T2) and six months after intervention (T3) . Results:After intervention, the longest articulation time, head control, lip strength, tongue extension range, left and right lip swing power of the observation group were higher than those of the control group, with statistical differences ( P<0.05) . At T1, T2 and T3, there were interaction, inter group and time effects in the assessment results of articulation syllables of children in the two groups, and the differences were statistically significant ( P<0.05) . The scores of the modified Frenchay Dysarthria Assessment (FDA) in the two groups had interaction, inter group and time effects, and the differences were statistically significant ( P<0.05) . Conclusions:In FAD children, the implementation of multiple integration correction training for articulation disorder can improve the motor function of articulation organs and the ability of articulation syllable repetition, thereby promoting the recovery of the children's speech function.

Objective:To explore the value of thromboela-stogram (TEG) in predicting the risk of bleeding in patients undergoing thyroid cancer surgery and guiding blood transfusion therapy.Methods:46 patients with hemorrhage after thyroid cancer surgery in General Surgery Department of the Second Hospital of Shanxi Medical University from Sep. 2021 to Sep. 2022 were selected as the hemorrhage group, including 12 males and 34 females. The age ranged from 18 to 76 years old, with an average age of (45.39±8.64). A total of 46 patients with no postoperative bleeding during the same period were selected as control group, including 9 males and 37 females. The average age was (43.86±9.12) years, ranging from 18 to 75 years. Postoperative TEG parameters, thrombin time (fibrinogen), fibrinogen (FIB), prothombin time (PT), thrombin time (thrombin time, TT), activited partial thomboplastin time (APTT) ], Spearman correlation coefficient was used to analyze the correlation between TEG parameters, coagulation parameters and postoperative blood loss. The value of TEG parameters and coagulation indexes in predicting bleeding was evaluated by receiver operating characteristic (ROC) curve.Results:R value (9.81±1.39) min, K value (3.52±0.94) min, PT value (14.12±1.98) s, TT value (21.36±3.21) s and APTT value (40.29±7.18) s in hemorrhage group were higher than those in control group (7.09±1.12) min and 2.75±0.81) min, (12.86±1.74) s, (19.71±2.53) s, (36.15±6.52) s, MA value (51.67±5.13) mm, Angle (47.06±9.24) °, FIB (1.95±0.64) g/L were lower than control group (57.76±6.05) mm, (58.29±10.28) °, (2.41±0.89) g/L (t 1=10.335, t 2=4.209, t 3=3.242, t 4=2.738, t 5=2.895, t 6=5.207, t 7=5.510, t 8=2.846, all P<0.05) ; R-value (11.02±1.26) min and K-value (4.16±0.93) min in patients with high blood (≥10 ml) bleeding group were higher than those in patients with low bleeding (<10 ml) (9.28±1.19) min and (3.24±0.89) min. MA value (48.04±5.01) mm, Angle (42.15±9.14) ° were lower than those of patients with hypohemorrhage (53.26±5.29) mm, (49.21±9.53) ° (t 1=4.484, t 2=3.183, t 3=3.127, t 4=2.340, P<0.05). The amount of blood loss after thyroid cancer surgery was positively correlated with R value and K value, and negatively correlated with MA value and Angle (r 1=0.421, r 2=0.335, r 3=-0.318, r 4=-0.306, all P<0.05). The area under the curve (AUC) of R value, K value, MA value and Angle predicted perioperative bleeding of thyroid cancer surgery was>0.7. R value (7.13±1.15) min, K value (2.81±0.82) min, PT (13.01±1.76) s, TT (20.03±2.60) s, APTT (37.12±6.64) s after treatment were lower than those before treatment (9.81±1.39) min, (3.52±0.94) min, (14.12±1.98) s, (21.36±3.21) s, (40.29±7.18) s, MA value (56.89±5.94) mm, Angle (56.73±9.86) °, FIB (2.35±0.85) g/L were higher than those before treatment (51.67±5.13) mm, (47.06±9.24) °, (1.95±0.64) g/L (t 1=10.076, t 2=3.860, t 3=2.842, t 4=2.184, t 5=2.198, t 6=4.511, t 7=4.854, t 8=2.550, all P<0.05) . Conclusion:TEG parameters R value, K value, MA value and Angle have certain predictive efficacy in predicting bleeding risk of patients undergoing thyroid cancer surgery, and can guide clinical transfusion therapy.

Objective: Schizophrenia (SCZ) is a severe psychiatric disorder with unknown etiology and lacking specific biomarkers. Herein, we aimed to explore plasma biomarkers relevant to SCZ using targeted metabolomics. Methods: Sixty drug-naïve SCZ patients and 36 healthy controls were recruited. Psychotic symptoms were assessed using the Positive and Negative Syndrome Scale. We analyzed the levels of 271 metabolites in plasma samples from all subjects using targeted metabolomics, and identified metabolites that differed significantly between the two groups. Then we evaluated the diagnostic power of the metabolites based on receiver operating characteristic curves, and explored metabolites associated with the psychotic symptoms in SCZ patients. Results: Twenty-six metabolites showed significant differences between SCZ patients and healthy controls. Among them, 12 metabolites were phosphatidylcholines and cortisol, ceramide (d18:1/22:0), acetylcarnitine, and γ-aminobutyric acid, which could significantly distinguish SCZ from healthy controls with the area under the curve (AUC) above 0.7. Further, a panel consisting of the above 4 metabolites had an excellent performance with an AUC of 0.867. In SCZ patients, phosphatidylcholines were positively related with positive symptoms, and cholic acid was positively associated with negative symptoms. Conclusion Our study provides insights into the metabolite alterations associated with SCZ and potential biomarkers for its diagnosis and symptom severity assessment.

Objective:To investigate the application effect of a sequential clinical skill curriculum system in standardized residency training.Methods:A total of 300 residents who participated in the residency training of a clinical medical school from 2020 to 2022 were selected as the research subjects, among whom 46 residents in the experimental group had received the clinical skill training course of the clinical medical school in the undergraduate stage, and 254 in the control group had not received such training in the undergraduate stage. The teaching effect of the two groups was observed from the first year to the third year after they entered the residency training base and were trained together based on the curriculum system. SPSS 24.0 statistical software was used for data analysis, and the main statistical methods included descriptive analysis, the Kolmogorov-Smirnov test, the Mann-Whitney U test, and the chi-square test. Results:Before the residents entered the residency base, class 2020 [60.0(52.0,60.0) vs. 51.0(48.0,53.0)], class 2021 [54.0(52.0,56.0) vs. 51.0(48.0,53.0)] and class 2022 [53.0(51.0,55.0) vs. 50.0(47.0,51.0)] The difference between the entry base grades of the residents in the experimental group compared to the control group was statistically significant ( P<0.05). After 36 months of residency training, the difference between the residents in the trial group and the control group in the 2020 class was not statistically significant when it came to the passing rate of the final exam ( χ2=1.20, P=0.273). At the end of 12 months of residency training, there was a statistically significant difference ( P<0.05) between the scores of residents in the experimental group compared with the control group in the theoretical examination [124.0 (123.8,125.0) vs. 115.0 (101.0,125.0)] and medical history taking [92.0 (91.0,95.0) vs. 85.1 (79.3,94.5)]. The differences were not statistically significant ( P>0.05) at the end of 6, 18, and 24 months of residency training. At the end of 6 months [93.0(90.0,97.0) vs. 89.0(86.3,95.0)], 12 months [94.0(92.0,95.0) vs. 89.0(87.0,92.0)] and 18 months [90.0(86.5,93.5) vs. 81.0(69.0,91.0)] of residency training, residents in the experimental group Physical examination scores were statistically significant compared to the control group ( P<0.05). At the end of 24 months of residency training, there was no statistically significant difference ( P>0.05) between the physical examination scores of residents in the experimental group compared with the control group in the classes of 2020 [92.0(87.5,95.3) vs. 85.0(79.0,92.0)] and 2021 [94.0(87.0,96.0) vs. 90.0(84.0,95.0)]. Conclusions:The clinical skill curriculum system can help to improve the comprehensive clinical ability of residents, and the teaching contents and methods of physical examination should be further optimized, with a focus on the training of doctor-patient communication skills and humanistic literacy among residents in the future.

In vitro studies have established the prevalent theory that the mitochondrial kinase PINK1 protects neurodegeneration by removing damaged mitochondria in Parkinson's disease (PD). However, difficulty in detecting endogenous PINK1 protein in rodent brains and cell lines has prevented the rigorous investigation of the in vivo role of PINK1. Here we report that PINK1 kinase form is selectively expressed in the human and monkey brains. CRISPR/Cas9-mediated deficiency of PINK1 causes similar neurodegeneration in the brains of fetal and adult monkeys as well as cultured monkey neurons without affecting mitochondrial protein expression and morphology. Importantly, PINK1 mutations in the primate brain and human cells reduce protein phosphorylation that is important for neuronal function and survival. Our findings suggest that PINK1 kinase activity rather than its mitochondrial function is essential for the neuronal survival in the primate brains and that its kinase dysfunction could be involved in the pathogenesis of PD.

Objective:To investigate the diagnostic value of circular RNA circ_100367 in thyroid cancer (THCA) and its relationship with immune-related factors.Methods:According to the data chip provided by the National Center for Biotechnology Information (NCBI) website, the differentially expressed circRNAs in THCA were analyzed, then circ_100367 was included in this study. The serum of 175 THCA patients and healthy people were collected, and the expression levels of circ_100367 and its linear transcript DCAF8 mRNA in serum samples were detected by qRT-PCR, and the correlation between circ_100367 and DCAF8 was calculated. The correlation between the expression of circ_100367 and the clinicopathological characteristicsof the patients, immune infiltration level and immunosuppressive factor PD-1 was analyzed.Results:Compared with serum of healthy people (1.00±0.37) , expression level of circ_100367 in serum of THCA patients was significantly increased (1.37±0.41) ( t=8.80, P<0.001) , and there was no significant difference in DCAF8 mRNA expression ( t=1.67, P=0.095) , but circ_100367 was positively correlated with DCAF8 mRNA expression ( r=0.17, P=0.028) . Analysis of expression and clinicopathological characteristics of circ_100367 showed that compared with patients in M0 group (1.26±0.40) , circ_100367 was overexpressed in M1 and Mx patients (1.43±0.40) ( t=2.63, P=0.009) ; compared with N0 patients (1.24±0.36) , circ_100367 was overexpressed in serum of N1 and Nx patients (1.45±0.42) ( t=3.48, P=0.001) ; compared with serum of patients with negative lymph node detection (1.28±0.36) , circ_100367 was overexpressed in serum of positive patients (1.42±0.43) ( t=2.14, P=0.034) ; compared with T1+T2 stage patients (1.30±0.37) , circ_100367 expression was overexpressed in serum ofT3+T4 patients (1.40±0.43) ( t=2.22, P=0.028) . Analysis of the expression and immune infiltration levels of circ_100367 found that highly expressed circ_100367 was associated with CD8+ T cells ( r=0.25, P=0.024) , macrophages ( r=0.22, P=0.038) , CD4+ T cells ( r=0.25, P=0.020) and B cell ( r=0.23, P=0.033) levels. The expression of circ_100367 was also positively correlated with the immunosuppressive factor PD-1 ( r=0.19, P=0.011) . Conclusion:circ_100367 can be used as a marker for the diagnosis of THCA and its expression is strongly correlated with immune-related factors.

As one of the most lethal diseases, pancreatic cancer shows a dismal overall prognosis and high resistance to most treatment modalities. Furthermore, pancreatic cancer escapes early detection during the curable period because early symptoms rarely emerge and specific markers for this disease have not been found. Although combinations of new drugs, multimodal therapies, and adjuvants prolong survival, most patients still relapse after surgery and eventually die. Consequently, the search for more effective treatments for pancreatic cancer is highly relevant and justified. As a newly re-discovered mediator of gasotransmission, hydrogen sulfide (H

Objective:To investigate the clinical characteristics and risk factors of bronchiolitis obliterans (BO) after adenovirus pneumonia.Methods:Clinical data of 266 children with adenovirus pneumonia hospitalized in Children′s Hospital of Soochow University from January 2011 to December 2017 were retrospectively analyzed.Accor-ding to whether they developed BO, children with adenovirus pneumonia were divided into the BO group and the non-BO group.Clinical features of the BO group and the non-BO group were compared by t test, rank sum test or chi square test.Risk factors were analyzed by Logistic regression approach. Results:Among 266 children with adenovirus pneumonia included, 37 patients were developed into BO group, and their age was significantly younger than that of the non-BO group [12.0(8.0, 17.5) months vs.32.0(13.0, 48.0) months, P<0.001]. Compared with the non-BO group, there were more proportion of preterm infants[10.8%(4/37 cases) vs.3.1%(7/229 cases), P=0.028], more instances of comorbidities [21.6%(8/37 cases) vs.4.4%(10/229), P<0.001] and more children with allergic diseas[35.1%(13/37 cases) vs.20.1%(46/229 cases), P=0.041] in the BO group, and the difference was statistically significant.The duration of fever in the BO group was significantly longer than that of the non-BO group [10(4.0, 13.5) d vs.6(4.0, 9.0) d, P=0.011] children with symptoms of wheezing, shortness of breath, and hypoxemia in the BO group were significantly more than the non-BO group[81.1%(30/37 cases) vs.27.9%(64/229 cases), P<0.001; 64.9%(24/37 cases) vs.5.7%(13/229 cases), P<0.001; 59.5%(22/37 cases) vs.6.6%(15/229 cases), P<0.001]. The platelet count, IgG level, and CD3 -CD 19+ lymphocyte percentage were significantly higher in the BO group than the non-BO group [(364±104)×10 9/L vs.(297±105)×10 9/L, P=0.001; 6.74(4.92, 10.16) g/L vs.5.93(1.00, 8.04) g/L, P=0.016; (33.5±15.3)% vs.(26.1±10.2)%, P=0.008]. In contrast, the percentage of CD3 + CD4 + lymphocytes in the BO group was lower than the non-BO group[(29.1±8.0)% vs.(32.5±9.4)%, P=0.044], the difference was statistically significant.The BO group had a higher rate of mixed bacterial infection than the non-BO groups[37.8%(14/37 cases) vs.16.6%(38/229 cases), P=0.003]. An age<26 months, comorbidities, premature birth history, wheezing, shortness of breath, and hypoxemia were independent risk factors for BO after adenovirus pneumonia( OR=4.808, 30.667, 7.558, 3.909, 8.842, 8.607, all P<0.05). Conclusions:An age of less than 26 months, a history of premature delivery comorbidities, wheezing, shortness of breath and hypoxemia, are independent risk factors for BO after adenovirus pneumonia.Children with above manifestations should receive high resolution CT as soon as possible to determine whether it is BO.
