Objective:To investigate the current status of pertussis laboratory diagnosis and confirmed pertussis cases reporting in Shaanxi Province, and evaluate the quality of case reports.Methods:The information of confirmed pertussis cases reported in Shaanxi Province from January to July 2022 was collected through the China Disease Control and Prevention Information System. The laboratory diagnostic methods and pertussis vaccine immunization history of confirmed cases were investigated, and the descriptive epidemiological method was used for statistical description.Results:Of the 164 confirmed cases of pertussis reported from January to July 2022, two were not tested in the laboratory and 162 were tested in the laboratory. The proportions of different detection methods were 1.85% (3/162) of isolation and culture, 31.48% (51/162) of serum antibody IgG, 14.20% (23/162) of serum antibody IgM, 49.38% (80/162) of serum antibody PCR and 3.09% (5/162) of serum antibody IgM+ PCR. Among the 79 serological positive cases, 12 cases (15.19%)had no history of pertussis immunization, and 15 cases (18.99%), 11 cases (13.92%) and 41 cases (51.90%) had the time interval from vaccination to detection of <1 year, 1-3 years and >3 years, respectively. Based on the analysis of laboratory testing methods and vaccination history, 38 cases were misdiagnosed/misreported among 164 cases, with a misdiagnosis or misreported rate of 23.17%. There were 17, 12 and 9 cases of misdiagnosis/misreport in 0-2 years old group, 3-6 years old group and≥7 years old group, and the misdiagnosis or misreported rates were 27.42%(17/62), 26.67%(12/45) and 15.79%(9/57), respectively.Conclusions:The selection of pertussis laboratory testing methods in some medical institutions in Shaanxi Province is incorrect, which leads to a certain proportion of misdiagnosis or misreport, and it is necessary to further strengthen the training and standardization.

ObjectiveSerum metabolomics of acute lung injury（ALI） in rats was conducted using ultra-performance liquid chromatography-quadrupole-time-of-flight mass spectrometry（UPLC-Q-TOF-MS） to explore the similarities and differences in the mechanism of Qingqiao（harvested when the fruits of Forsythiae Fructus were initially ripe and still green in color） and Laoqiao（harvested when the fruits of Forsythiae Fructus were ripe） in the treatment of ALI. MethodA total of 24 SD male rats were acclimatized and fed for 1 week， 6 of them were randomly selected for the blank group and 18 for the experimental group. The ALI model was induced in the experimental group by tracheal intubation with lipopolysaccharide（LPS）. After successfully constructing the ALI model， these rats was randomly divided into model group， Qingqiao group and Laoqiao group， with 6 rats in each group. The Qingqiao and Laoqiao groups were administered orally once a day at a dose of 1.5 g·kg^-1， while the blank and model groups received an equivalent volume of saline for 3 consecutive days. The pathological conditions of rat lung tissues were comprehensively assessed by hematoxylin-eosin（HE） staining， wet-to-dry mass ratio（W/D） of lung tissues， and protein concentration in rat bronchoalveolar lavage fluid（BALF）. The levels of interleukin（IL）-6， IL-1β and tumor necrosis factor（TNF）-α in BALF were quantified using enzyme-linked immunosorbent assay（ELISA）. UPLC-Q-TOF-MS was used to identify and analyze the chemical compositions of Qingqiao and Laoqiao， and serum metabolomics of rats in each group was analyzed， combined with multivariate statistical analysis with variable importance in the projection（VIP） value>1， P<0.05 from t-test， and fold change（FC）≥1.5 or FC≤0.5 to screen the differential metabolites Qingqiao and Laoqiao for the treatment of ALI. The Kyoto Encyclopedia of Genes and Genomes（KEGG） database was used in combination with MetaboAnalyst for the metabolic pathway analysis of the screened differential metabolites. ResultCompared with the blank group， rats in the model group exhibited enlarged alveolar lumen， ruptured alveoli， interstitial hemorrhage， bronchial exudation of a large number of neutrophils and erythrocytes， and a significant increase in the protein concentration in the BALF and the W/D value of the lung tissues（P<0.01）. In contrast， compared with the model group， rats in the Qingqiao group and the Laoqiao group showed reduced bronchial hemorrhage in the lungs， and the protein concentration in the BALF and the W/D value of the lung tissues were significantly decreased（P<0.01）， the lung injury was significantly alleviated， but more obvious in the Qingqiao group. Compared with the blank group， the expression levels of IL-6， IL-1β and TNF-α in the BALF of the model group were significantly higher（P<0.01）. Additionally， compared with the model group， the expression levels of IL-6， IL-1β and TNF-α in the Qingqiao and Laoqiao groups were significantly lower（P<0.01）. The chemical composition analysis of Qingqiao and Laoqiao revealed that 63 components were detected in Qingqiao and 55 components were detected in Laoqiao， with 47 common components， 16 components unique to Qingqiao and 8 components unique to Laoqiao. Characterizing the differences in serum metabolomics in rats， 19 and 12 metabolites were called back by Qingqiao and Laoqiao， respectively. The metabolic pathway enrichment analysis showed that Qingqiao exerted its therapeutic effects by affecting 6 key metabolic pathways， including linoleic acid metabolism， phenylalanine metabolism， phenylalanine， tyrosine and tryptophan biosynthesis， glycerophospholipid metabolism， α-linolenic acid metabolism， and arachidonic acid metabolism， and Laoqiao exerted therapeutic effects by affecting 6 key metabolic pathways， including linoleic acid metabolism， arachidonic acid metabolism， sphingolipid metabolism， phenylalanine metabolism， ascorbate and aldarate metabolism， and glycerophospholipid metabolism. ConclusionQingqiao and Laoqiao have therapeutic effects on ALI， and Qingqiao is more effective. Both of them can play a therapeutic role in ALI by regulating amino acid metabolism and lipid metabolism， but the metabolic pathways affected by them are different.

The weight of the first-level index structure index was 0.266, and the highest weight among the second-level indexes was the operational development ability (0.083), while the highest weight among the third-level indexes of operational development ability was the comprehensive coordination ability (0.193); The weight of the first-level index process index was 0.405, and the corresponding second-level and third-level indexes with the highest weight were department operation practice work (0.157) and reasonable resource allocation (0.303), respectively; The weight of the first-level index result index was 0.329, and the corresponding second-level and third-level indexes with the highest weight were the weight of medical quality and safety (0.103) and drug adverse reaction reporting rate (0.237), respectively.Conclusions:The evaluation index system constructed in this study proves scientific and reasonable in weight assignment, proving a reference for the management of the specialist service operation assistants.

Effective supervision of the clinical research management department can guarantee and improve the quality of the investigator initiated trials(IIT). The authors analyzed relevant clinical research regulations and literature and summarized the current situation of risk-based IIT project process quality management. On such basis, they determined the risk-based IIT project process quality management method in combination with the previous research of the research group.From 2021 to 2022, this method was used to implement process quality management for 353 IIT projects in Shanghai′s tertiary hospitals. More than 3 000 risk points were identified through centralized supervision, and then on-site supervision was carried out to correct the problems found. As proven by the results, the method could find existing problems in time and define the risk level of the project, and also formulate an individualized risk supervision plan accordingly, so as to effectively ensure the data reliability and scientific results. It is suggested that the clinical research management department implement risk based management for the whole process of IIT projects, increase funding and staffing, and implement hierarchical management for the projects by research types, so as to promote the sustainable development of IITs.

【Objective】 To explore the factors affecting NAT reactive blood donors re-entry, so as to provide data support for formulation of scientific and reasonable strategy. 【Methods】 The basic data and laboratory test results of 174 NAT reactive returning blood donors from January 2019 to August 2021 were collected and statistically analyzed by logistic regression. 【Results】 Among 174 HBV DNA reactive blood donors applying for re-entry, 81 (46.6%) were eligible for re-entry. Blood donation type and deconstructed Ct value were independent influencing factors of blood donors’ re-entry (P<0.05). The Ct value of minipool and deconstruction test showed significant affection on the re-entry (P<0.05). Donors with minipool-Ct-value exceeding deconstructed-Ct-value had a low likelihood of success with re-entry(P>0.05). No significant difference was observed in Ct values of deconstruction test, first re-entry test and second re-entry test (P<0.05). 【Conclusion】 In view of the low re-entry rate of NAT reactive blood donors, it is necessary to establish a set of safety criteria to lessen workloads. Donors with exceeding minipool-Ct-values, repeat reactive by two NAT reagents, failure in the first re-entry test are suggested to be deferred permanently.

Objective:To explore the effect of iron overload on the cognitive function of rats and its possible internal mechanism.Methods:Thirty 8-week-old male Sprague Dawley rats of SPF degree were randomly divided into 2 groups, iron overload group(IO group) and control group(Sham group), with 15 in each group.The rats in IO group were injected intraperitoneally iron dextran(100 mg/(kg·d)) for 28 days.The cognitive function of rats was detected by Morris water maze method. Western blot method was used to detect the expression of TfR1 and autophagy-related protein p-AMPK, LC3 and Beclin1 in the hippocampus of rats. Immunofluorescence was used to observe the expression of LC3 and Beclin1 in the hippocampus of rats. HE staining was used to observe the morphological changes of neurons in the hippocampus. Transmission electron microscopy was used to observe the number of autophagosomes and the morphology of endoplasmic reticulum in hippocampus.The software of SPSS 20.0 was used for repeated measurement ANOVA and t-test. Results:Morris water maze test showed that there were significant interaction between the group factor and training time factor of escape latency( F=3.55, P<0.01). And the simple effect analysis showed that compared with the Sham group((28.09±18.41)s, (21.42±15.53)s, (16.96±8.35)s, (10.24±3.75)s), the average escape latency of rats(2nd-5th day) in IO group((56.68±30.65)s, (58.21±36.09)s, (36.58±13.54)s, (27.29±14.30)s )were significantly longer ( t=8.57, 6.81, 9.51, 7.12, P<0.01). The platform was removed on 6th day of the space exploration experiment, compared with the Sham group ((41.89±3.89)%), the percentage of time spent in the target quadrant of IO group ((25.46±3.56)%) was significantly decreased( t=24.06, P<0.01). Western blot showed that the relative expression levels of (TfR1 (2.10±0.48), p-AMPK (0.74±0.10), LC3 (1.11±0.40), Beclin1 (1.05±0.20)) in IO group in the hippocampus of the rats were significantly higher than those of the Sham group(TfR1(0.11±0.18), p-AMPK(0.19±0.02), LC3(0.22±0.11), Beclin1(0.17±0.02))( t=1.58, 14.58, 10.06, 20.65, P<0.01)). HE staining showed that compared with the Sham group, the neuron in the hippocampus of the IO group were sparsely arranged, morphologically irregular, and the number of the neurons was significantly reduced. Transmission electron microscopy showed that compared with the Sham group, the number of autophagosomes in the hippocampus of IO group was increased. Conclusion:Iron overload may exert its neurotoxic effect by increasing the level of autophagy in the hippocampus, causing cognitive dysfunction.
