Objective:To explore the non-bacterial pathogen distribution, epidemiological characteristics, and clinical features of acute respiratory infections in children in Sichuan Province.Methods:Using a retrospective cohort study method, this study selected hospitalized children diagnosed with acute respiratory infections at West China Second Hospital of Sichuan University from February 2019 to January 2021, and tested 13 pathogens using polymerase chain reaction (PCR)-fragment analysis. The children were divided into infant group (<1 year old), toddler group (1 year old ≤ age <3 years old), preschool group (3 years old ≤ age <6 years old) and school-age group (6 years old ≤ age <18 years old). The distribution of pathogen positive rates, seasonal epidemic characteristics, clinical characteristics, and some laboratory test indicators were analyzed in children. Statistical analysis was performed on the results using SPSS 22.0 software, with count data expressed as percentages and inter group comparisons using SPSS 22.0 software χ2 Inspection. Results:A total of 2 922 pediatric patients were included in this study, with 1 748 (59.8%) positive for pathogens detected. Among them, 1 391 (79.6%) were detected as a single pathogen, and 357 (20.4%) were detected as a mixture of two or more pathogens. The most commonly detected pathogens were rhinovirus (HRV) (39.7%), syncytial virus (RSV) (22.8%), and parainfluenza virus (PIV) (12.5%). Pathogen positivity is more common in children under 6 years old ( χ2=146.59, P<0.001), with a slightly higher positivity rate in male children (61.3%, 1 047/1 707) than in female children (57.7%, 701/1 215) ( χ2=3.91, P=0.048), and compared with pathogen negative children, positive children are more prone to symptoms such as cough, wheezing, and shortness of breath ( χ2=259.15, 366.06, 12.48, P<0.001). The distribution of different pathogens varies among children of different age groups, and HRV is more common in children aged 1-3 and 3-6 years old ( χ2=9.74, P<0.001), while RSV is more common in children under 1 year old ( χ2=178.63, P<0.001), while mycoplasma pneumoniae (MP) and influenza virus (InfA/B) are less common in children under 1 year old ( χ2=92.54, 12.90,22.21, P<0.01). The prevalence of multiple pathogens showed seasonal changes. HRV showed a high prevalence trend in spring and autumn, while the prevalence of RSV infection was mainly seen in autumn and winter festivals. The positive rate of different pathogens after the outbreak of novel coronavirus pneumonia was significantly lower than that before the outbreak ( χ2=252.68, P<0.001). Conclusion:The detection rate of non-bacterial respiratory pathogens in children in Sichuan Province from 2019 to 2021 is high, which is prone to symptoms such as cough, wheezing, and shortness of breath, with HRV and RSV being the main types. The positive rate of respiratory pathogens varies among different age groups, genders, and seasons.

In situ and real-time monitoring of responsive drug release is critical for the assessment of pharmacodynamics in chemotherapy. In this study, a novel pH-responsive nanosystem is proposed for real-time monitoring of drug release and chemo-phototherapy by surface-enhanced Raman spectroscopy (SERS). The Fe₃O₄@Au@Ag nanoparticles (NPs) deposited graphene oxide (GO) nanocomposites with a high SERS activity and stability are synthesized and labeled with a Raman reporter 4-mercaptophenylboronic acid (4-MPBA) to form SERS probes (GO-Fe₃O₄@Au@Ag-MPBA). Furthermore, doxorubicin (DOX) is attached to SERS probes through a pH-responsive linker boronic ester (GO-Fe₃O₄@Au@Ag-MPBA-DOX), accompanying the 4-MPBA signal change in SERS. After the entry into tumor, the breakage of boronic ester in the acidic environment gives rise to the release of DOX and the recovery of 4-MPBA SERS signal. Thus, the DOX dynamic release can be monitored by the real-time changes of 4-MPBA SERS spectra. Additionally, the strong T₂ magnetic resonance (MR) signal and NIR photothermal transduction efficiency of the nanocomposites make it available for MR imaging and photothermal therapy (PTT). Altogether, this GO-Fe₃O₄@Au@Ag-MPBA-DOX can simultaneously fulfill the synergistic combination of cancer cell targeting, pH-sensitive drug release, SERS-traceable detection and MR imaging, endowing it great potential for SERS/MR imaging-guided efficient chemo-phototherapy on cancer treatment.

Objective: To investigate the specifity of amyloid precursor protein(APP), brain derived neurotrophic factor (BDNF)and gamma aminobutyric acid(GABA) in peripheral blood in children with autism spectrum disorder, so as to explore the biomarkers for early screening of ASD and its relationship with the severity of ASD. Methods: A total of 41 children diagnosed with autism from January to December 2019 were enrolled in the ASD group. Meanwhile, 41 healthy children with normal growth and development who were examined in the same period were selected as control group. And the sera total sAPP, sAPP α, sAPP β, BDNF and GABA of all participants were tested by sensitive enzyme linked immunosorbent assay method, and were compared between the two groups. Results: The serum sAPP level in ASD group(2 132.98±333.28 ng/mL) was higher than control group(1 734.76 ±357.97 ng/mL),the serum sAPP α level(335.11±33.87 pg/mL) was higher than control group(274.84±32.12 pg/mL) and the serum GABA level(4.17±0.95 μmol/L)was lower than control group(6.35±0.84 μmol/L). GABA level (4.17±0.95 μmol/L) was lower than that of control group (6.35±0.84 μmol/L), the differences were statistically significant ( t =3.92, 4.25, -7.27, P < 0.05 ). In addition, the serum GABA level in children with severe ASD (3.48±0.77 μmol/L)was lower than children with mild to moderate (4.94±0.98 μmol/L).The difference was significant ( t =-3.31, P <0.05). ROC curve showed that total sAPP( AUC = 0.77 ,95% CI =0.66-0.87), sAPP α( AUC =0.77,95%CI=0.67-0.87), and GABA ( AUC =0.95,95% CI =0.90-0.93)had diagnostic efficacy for ASD( P <0.05), among which the AUC of GABA was the largest (0.95)and its sensitivity(85.65%) and specificity(80.76%) were the highest. The results of binary Logistic regression showed that the abnormal expression of sAPPα ( OR =1.04,95% CI = 1.00- 1.07) and GABA( OR =0.02,95% CI =0.00-0.32) were associated with risk for ASD( P <0.05). Conclusion Considering the specific change of total sAPP, sAPPα andGABA in peripheral blood in ASD children, total sAPP, sAPP α and GABA can be considered as promising biomarkers in the early diagnosis of ASD, among which GABA has the highest sensitivity and specificity.

Objective:To investigate the effect of conventional treatment plus long-term transcranial direct current stimulation (tDCS) on consciousness recovery in patients with minimally conscious state (MCS) after traumatic brain injury (TBI).Methods:A retrospective cohort study was conducted to analyze the clinical data of 60 patients with MCS after TBI admitted to Zhejiang Armed Police Corps Hospital from January 2019 to December 2020, including 38 males and 22 females, aged 19-60 years [(45.7±11.4)years]. Course of disease was 3-6 months [(4.6±0.9)months]. Of all, 30 patients received internal medicine, hyperbaric oxygen, rehabilitation and other conventional treatment (conventional treatment group), and 30 patients received tDCS stimulation on the basis of conventional treatment (tDCS treatment group). The tDCS stimulation contained 4 cycles for 28 days with each cycle lasting for 7 days (stimulation for 5 days, rest for 2 days). Coma recovery scale-revised (CRS-R) total score, brainstem auditory evoked potential (BAEP) score and clinical effictive rate (significantly effective+effective) were compared between the two groups before treatment, during 4 cycles of treatment and at 6 months and 12 months after treatment. Complications induced by tDCS were also evaluated.Results:There was no significant difference in CRS-R total score and BAEP score between the two groups before treatment (all P>0.05). CRS-R total score and BAEP score in tDCS treatment group were significantly higher than those in conventional treatment group during 4 cycles of treatment and at 6 months and 12 months after treatment (all P<0.05). CRS-R total score and BAEP score in both groups gradually increased during 4 cycles of treatment and at 6 months and 12 months after treatment (all P<0.05). The clinical effective rate in tDCS treatment group was 73% (22/30) when compared to 57% (17/30) in conventional treatment group ( P<0.05). In tDCS treatment group, 10 patients had local reversible slight redness at the cathodal position, while no other serious adverse effects, such as local burns, ulceration, exudation or epilepsy. Conclusion:Compared with conventional treatment, conventional treatment plus long-term tDCS can be more effective in improving the state of consciousness without serious adverse effects for MCS patients after TBI.

OBJECTIVE: To explore the relationship between adversity quotient and professional values in standardized-trained nurses. METHODS: OBJECTIVE: sampling method was adopted, 502 nurses who received standardized training from third class A hospitals were selected as research subjects. Questionnaire survey was carried out by Adversity Quotient Scale and Weis Nurses Professional Values Scale-Revised to calculate standardized scores of adversity quotient and professional values. RESULTS: The standardized scores of adversity quotient and professional values in the standardized-trained nurses were(3.2±0.4) and(3.8±0.6). The standardized scores of professional values, care provision, activism, responsibility, freedom and safety, and trust in standardized-trained nurses were positively correlated with the standardized score of adversity quotient(correlation coefficients were 0.192, 0.160, 0.179, 0.227, 0.166, P<0.01). Multiple linear regression analysis results showed that the higher the score of freedom and safety in standardized-trained nurses, the higher the level of adversity quotient(P<0.01). The level of adversity quotient of those who are satisfied with their position was higher than those who are indifferent to their position(P<0.01). CONCLUSION: The adversity quotient of standardized-trained nurses is positively correlated with their professional values. The level of adversity quotient of standardized-trained nurses can be improved by cultivating good professional values to stabilize the clinical nursing team.

Objective:To compare the evaluation value of Glascow-Scoring Scoring System (GBS) and Modified Glascow-Scoring System (mGBS) for clinical intervention and prognosis of patients with non-varicose gastrointestinal bleeding.Methods:The convenient sampling method was used to retrospectively analyze 254 patients with non-varicose gastrointestinal bleeding who were admitted to a Class Ⅲ Grade A hospital in Anhui province from January 2017 to May 2018, and GBS and revised GBS scores of all patients were calculated. The value of the two scoring systems in predicting of rebleeding rate during hospitalization, blood transfusion, endoscopic intervention, deaths of patients and the rate of patients transferring to ICU.Results:Area under the ROC curve ( AUC) of GBS scoring system for blood transfusion, rebleeding, death and ICU transfer in patients with non-varicose gastrointestinal bleeding were 0.761, 0.714, 0.865 and 0.829, respectively. AUC of mGBS scoring system for blood transfusion, rebleeding, death and ICU transfer in non-varicose gastrointestinal bleeding patients were 0.753, 0.718, 0.871 and 0.792, respectively. Both scoring systems had good predictive ability. The predicted AUC of GBS scoring system for endoscopic intervention was 0.540, and that of mGBS scoring system was 0.542, showing a low predictive value. The cut-off points for blood transfusion, rebleeding, death and transfer to ICU were respectively 8, 11, 12, and 11 for the GBS scoring system, and those were respectively 7, 8, 10, and 11 for mGBS scoring system. The optimal cutoff point increased with the increase of disease severity, and there was no statistically significant difference between the two scoring systems ( P>0.05) . Conclusions:Both scoring systems can better predict the disease intervention needs and prognosis of patients with non-varicose gastrointestinal bleeding. It is recommended to use the simpler and modified GBS scoring system in clinical practice.
