OBJECTIVE To study the difference of Huangqin decoction combined with Paeoniae Radix Alba(BS) and Paeoniae Radix Rubra(CS)'s effect on ulcerative colitis(UC) based on network pharmacological analysis and animal experiment. METHODS The active constituents of BS and CS were retrieved from TCMSP database and literature, and the potential target was predicted by Swiss Target Prediction. Ulcerative Colitis was used as key words to search disease targets in DisGenet, OMIM, and Genecard databases. The intersection target was obtained by Venny 2.1.0. Cytoscape 3.7.2 software was used to construct network of drug-consumption targets. The STRING platform was used for protein-protein interaction(PPI) network analysis, and Metascape database was applied for GO/WIKI analysis. A dextran sulfate sodium(DSS) induced UC mouse model was established to compare the anti-UC effects of Huangqing decoction combined with BS(HQT-BS) and CS(HQT-CS), respectively. RESULTS There were 7 active components of HQT-BS and 11 active components of HQT-CS in the treatment of ulcerative colitis, respectively, 5 of which were the same. There were 146 and 157 targets respectively, 106 of which were the same. The core targets of HQT-BS were SRC, HSP90AA1, and PIK3R1, while the core targets of HQT-CS were SRC, HSP90AA1, and STAT3. WIKI enrichment analysis showed that several signaling pathways were shared by both BS and CS, such as EGFR tyrosine kinase inhibitor resistance, Notch signaling pathway. EGF/EGFR signaling pathway was the specific pathway related to BS, while Nuclear receptors meta-pathway and Kit receptor signaling pathway were the specific pathways related to CS, respectively. Animal experiments showed that both HQT-BS and HQT-CS could significantly improve colon shortening and tissue pathological alternation induced by DSS. However, HQT-CS was more effective in reducing the expression of interleukin-6 and neurogenic locus notch homolog protein1. CONCLUSION Both HQT-BS and HQT-CS have anti-UC effect, and HQT-CS is the better one.

Objective To investigate the effect of Versican V0/V1 on biological behaviors of mouse dental papilla cells(mDPCs).Methods mDPCs were isolated from C57BL/6J mice at embryonic day 16.5(E16.5).A small interfering RNA(siRNA)constructed specifically for Versican V0/V1 was transfected into mDPCs.The silencing efficiency was verified by quantitative real-time fluorescence polymerase chain reaction(qRT-PCR)and immunofluorescence staining.The proliferation rate of mDPCs was determined using EdU assay;the migration ability of mDPCs was evaluated by scratch test and transwell assay.Alkaline phosphatase(ALP)staining and aliz-arin red staining were used to assess the mineralization capability of mDPCs.The molecules related to odontogenic differentiation and mineralization at mRNA levels were measured by qRT-PCR.Results After siRNA transfection,the mDPCs of si-Versican V0/V1 group showed weaker proliferation and migration abilities compared with si-NC group(P＜0.01).An enhanced ALP staining intensity,miner-alized nodule formation and up-regulations of the molecules related to odontogenic differentiation and mineralization at mRNA levels(P＜0.05)were observed in the mDPCs of si-Versican V0/V1 group.Conclusion Versican V0/V1 silencing inhibits the proliferation and migration of mDPCs,but enhances the abilities of odontogenic differentiation and mineralization.

Objective:The aim of noise quality management for ICU patients was to explore the clinical feasibility of noise quality management.Methods:A randomized controlled trial method and convenient sampling method were used to select 240 patients treated in the ICU of Shanghai Fengxian District Central Hospital from April 2021 to March 2023 as the study objects. According to the time of admission, 120 patients admitted from April 2021 to March 2022 were divided into the control group. A total of 120 patients admitted to hospital from April 2022 to March 2023 were included in the intervention group. The control group was given routine care, and noise quality management was implemented in the intervention group on the basis of routine care. The noise decibel value, sleep quality, incidence of delirium and patient satisfaction of the two groups were compared.Results:In the intervention group, there were 69 males and 51 females, aged (56.08 ± 5.74) years old. The control group included 68 males and 52 females, aged (56.11 ± 5.72) years old. The decibels of day and night in ICU of the intervention group were (42.62 ± 1.33) and (38.72 ± 1.28) dB, which were lower than those of the control group (67.49 ± 2.36) and (59.65 ± 2.37) dB, with statistically significant differences ( t=100.57, 85.12, both P<0.05). Total score of sleep quality of patients in the intervention group (78.40 ± 5.86) was higher than that of the control group (60.49 ± 6.25), with statistically significant differences ( t=24.32, P<0.05). The incidence of delirium in the intervention group 12.50%(15/120), was lower than that in the control group 26.67%(32/120) with a statistically significant difference ( χ2=7.65, P<0.05). Satisfaction of patients in the intervention group 97.50%(117/120) was higher than that in the control group 90.00%(108/120), with a statistically significant difference ( χ2=5.76, P<0.05). Conclusions:The application of noise quality management for ICU patients is conducive to improving the overall environment of the ward, improving the sleep quality of patients, reducing the occurrence of patients′ delirium and improving patient satisfaction.

Objective To study the impact of a subject's testing state on residual noise level and ABR wave V amplitude during non-sedated ABR testing using Kalman-weighted averaging(KWA).Methods Twenty-one adults(18～34 years old,42 ears)with normal hearing were enrolled for non-sedated ABR testing under three different states(lying,sitting,and writing)in a quiet room using a new Kalman-weighted averaging ABR system(vivosonic integrity system).The residual noise level and the amplitude of wave V for click ABR(cABR)of each subject were recorded.The traditional ABR test system(interacoustics,IA)was also used to record ABR with the residual noise level and the amplitude of wave V measured at the same time.Results ① There was no significant difference in am-plitude of wave V between traditional ABR and non-sedated ABR in three different testing states(P＞0.05).②The residual noise levels in the lying and sitting states of KWA ABR were lower than those of traditional ABR,but there was no statistically difference(P＜0.05).The residual noise level of the KWA ABR system in writing state was significantly higher than that of the other three conditions(P＜0.05).③ There was no significant difference between the left and right ears in the residual noise level and amplitude of wave V for non-sedated ABR in writing state(P＞0.05).Conclusion Compared with traditional ABR,the non-sedated KWA ABR system in uriting state was significantly higher than that of the other three conolitions.Haw ever,the residual noise level in lying and sit-ting states had no significant difference with conditional ABR,and different states of the subject had impact on the residual noise level in the ABR testing to sone extent.

BACKGROUND: Patients with mass-forming pancreatitis (MFP) or pancreatic ductal adenocarcinoma (PDAC) presented similar clinical symptoms, but required different treatment approaches and had different survival outcomes. This meta-analysis aimed to compare the diagnostic performance of contrast-enhanced ultrasound (CEUS) and contrast-enhanced computed tomography (CECT) in differentiating MFP from PDAC. METHODS: A literature search was performed in the PubMed, EMBASE (Ovid), Cochrane Library (CENTRAL), China National Knowledge Infrastructure (CNKI), Weipu (VIP), and WanFang databases to identify original studies published from inception to August 20, 2021. Studies reporting the diagnostic performances of CEUS and CECT for differentiating MFP from PDAC were included. The meta-analysis was performed with Stata 15.0 software. The outcomes included the pooled sensitivity, specificity, positive likelihood ratio (+LR), negative likelihood ratio (-LR), diagnostic odds ratio (DOR), and summary receiver operating characteristic (SROC) curves of CEUS and CECT. Meta-regression was conducted to investigate heterogeneity. Bayesian network meta-analysis was conducted to indirectly compare the overall diagnostic performance. RESULTS: Twenty-six studies with 2115 pancreatic masses were included. The pooled sensitivity and specificity of CEUS for MFP were 82% (95% confidence interval [CI], 73%-88%; I2  = 0.00%) and 95% (95% CI, 90%-97%; I2  = 63.44%), respectively; the overall +LR, -LR, and DOR values were 15.12 (95% CI, 7.61-30.01), 0.19 (95% CI, 0.13-0.29), and 78.91 (95% CI, 30.94-201.27), respectively; and the area under the SROC curve (AUC) was 0.90 (95% CI, 0.87-92). However, the overall sensitivity and specificity of CECT were 81% (95% CI, 75-85%; I2  = 66.37%) and 94% (95% CI, 90-96%; I2  = 74.87%); the overall +LR, -LR, and DOR values were 12.91 (95% CI, 7.86-21.20), 0.21 (95% CI, 0.16-0.27), and 62.53 (95% CI, 34.45-113.51), respectively; and, the SROC AUC was 0.92 (95% CI, 0.90-0.94). The overall diagnostic accuracy of CEUS was comparable to that of CECT for the differential diagnosis of MFP and PDAC (relative DOR 1.26, 95% CI [0.42-3.83], P  > 0.05). CONCLUSIONS CEUS and CECT have comparable diagnostic performance for differentiating MFP from PDAC, and should be considered as mutually complementary diagnostic tools for suspected focal pancreatic lesions.

Objective To understand the quality of life in patients with pulmonary tuberculosis within three years after treatment， determine its related factors， and make suggestions for improving the short-term quality of life in patients with pulmonary tuberculosis after treatment. Methods A telephone survey was used to investigate registered tuberculosis patients in Shanghai in 2018 using the short form 12 （SF-12） and the chronic obstructive pulmonary disease （COPD） assessment test questionnaire （CAT）. Results A total of 975 patients with pulmonary tuberculosis who had completed the treatment were included in the study. The total physiological score was determined to be 49.18±10.25， and the total psychological score was 50.27±8.03 （t=5.62，P<0.000 1）. The average CAT score was 13.31±6.08. Multivariate linear regression analysis showed that quality of life was positively associated with high educational level， high monthly family income， and frequent physical exercise， whereas negatively associated with comorbidities， low self-care ability， and changing jobs. Conclusion We should pay more attention to the patients with pulmonary tuberculosis coexistent with COPD and other lung diseases. Measures should be implemented for the improvement in the quality of life， including providing financial support， encouraging regular exercise， and improving lung function.

Deciphering the metabolites of multiple components in herbal medicine has far-reaching significance for revealing pharmacodynamic ingredients.However,most chemical components of herbal medicine are secondary metabolites with low content whose in vivo metabolites are close to trace amounts,making it difficult to achieve comprehensive detection and identification.In this paper,an efficient strategy was proposed:herb-derived metabolites were predicted according to the structural characteristics and metabolic reactions of chemical constituents in Corydalis Rhizoma and chemical structure screening tables for metabolites were conducted.The fragmentation patterns were summarized from represen-tative standards combining with specific cleavage behaviors to deduce structures of metabolites.Ion abundance plays an important role in compound identification,and high ion abundance can improve identification accuracy.The types of metabolites in different biological samples were very similar,but their ion abundance might be different.Therefore,for trace metabolites in biological samples,we used the following two methods to process:metabolites of high dose herbal extract were analyzed to char-acterize those of clinical dose herbal extracts in the same biological samples;cross-mapping of different biological samples was applied to identify trace metabolites based on the fact that a metabolite has different ion abundance in different biological samples.Compared with not using this strategy,44 more metabolites of clinical dose herbal extract were detected.This study improved the depth,breadth,and accuracy of current methods for herb-derived metabolites characterization.

Objective:To understand and determine the biological properties of Chlamydia pneumonia (Cpn) hypothetical protein Cpn0423 and the mechanisms of which involved in Cpn0423-induced inflammatory response. Methods:The biological properties of Cpn0423 gene were analyzed using bioinformatic software. The subcellular localization of nucleotide-binding oligomerization domain-like receptor 2 (NOD2) in bone marrow-derived macrophages (BMDMs) was detected by confocal microscope. NOD2-siRNA was used to inhibit the expression of NOD2 at mRNA level. Cpn0423-induced macrophage inflammatory protein 2 (MIP-2) and IL-6 production in BMDMs were detected by ELISA. PCR was performed to detect Cpn0423 DNA in bronchoalveolar lavage fluid (BALF) of Cpn-positive patients.Results:The homology between Cpn0423 and other type Ⅲ secretion system effector proteins of Chlamydia ranged from 85% to 93%. NOD2-siRNA could effectively inhibit the expression of NOD2 at mRNA level in BMDMs ( P<0.001). Moreover, Cpn0423-induced production of MIP-2 [(920.5±99.1) pg/ml vs (130.1±11.5) pg/ml, P<0.001] and IL-6 [(266.2±58.4) pg/ml vs (165.7±21.5) pg/ml, P<0.001] in BMDMs were decreased following NOD2-siRNA pre-treatment. Cpn0423 DNA was detected in the BAlF of 83.3% (10/12) of Cpn-positive cases, but not in Cpn-negative cases. Conclusions:Cpn0423 induced inflammatory response in host cells through NOD2 pathway, which was closely related to the chronic inflammatory injury caused by Cpn.

Objective To investigate the roles of ultrasound,laboratory methods,and genetic diagnostic techniques in screening and diagnosing fetuses with an unbalanced recombination of chromosome 18[rec(18)] due to parental pericentric inversion,and the relationship between rec(18) fetal phenotypes and their recombinant chromosomes.Methods We analyzed two pedigrees with pericentric inversion of chromosome 18 (including the fetuses and their parents) which received prenatal diagnosis and genetic counseling on March 2017 and March 2018 respectively at Xiamen Maternity and Children Health Care Hospital through karyotype analysis,chromosome microarray analysis(CMA) and fluorescence in situ hybridization (FISH).Literatures were retrieved from Scientific Citation Index,PubMed,China National Knowledge Infrastructure(CNKI) and Wanfang Data from 1970 to June 2018.The genetic counseling records,ultrasound and laboratory findings,pregnancy outcomes of families with pericentric inversion of chromosome 18 in this study and the included literatures were reported and analyzed.Results Non-invasive prenatal testing (NIPT) of one case indicated high risk of fetal trisomy 18 at 22 weeks of gestation.And the imaging examination indicated that fetus had interventricular septal defect and micrognathia at 24+2 weeks.Prenatal diagnosis confirmed that the fetal karyotype was 46,XY,rec(1 8)dup(18q) inv(18)(p1 1.32q12.1) pat,which was originated from his father whose karyotype was 46,XY,inv(1 8)(p1 1.32q12.1).In the other case,serum screening testing indicated high risk of fetal trisomy 18 at 12+3 weeks.Imaging examination indicated that fetus had thickened nuchal translucency at 13+3 weeks and bilateral choroid plexus cysts at 15+6 weeks.Prenatal diagnosis confirmed that the fetal karyotype was 46,XY,rec(18)dup(18q)inv(18) (p11.32q12.1) mat,which was originated from his mother whose karyotype was 46,XX,inv(18)(p11.32q12.1).Among the nine fetuses,including seven from five pedigrees reported in the literature retrieved and two from the two pedigrees we reported,seven showed abnormal soft markers or structures in ultrasound and three of the seven pedigrees had high risk of fetal trisomy 18.Conclusions Ultrasound screening is highly sensitive in detecting rec(18) fetuses,yet the association between ultrasound features and fetal karyotypes is not clear.The combination of multiple genetic analysis methods,including karyotype analysis,CMA and FISH,may be conducive to clarifying the types and sources of complex derived chromosomes.

Objective To investigate the significance of serum adenosine deaminase level in type 1 diabe-tes patients(T1DM)with acute or chronic diabetes complications. Methods One hundred and eighty-four cases of type 1 diabetes patients were divided into three groups:T1DM without any complications(n = 55),T1DM with acute diabetes complications(n = 47)and T1DM with chronic diabetes complications(n = 82). We also enrolled 108 healthy persons as the control group.The clinical and biochemical data were collected and the influencing fac-tors of serum ADA were analyzed. Resultes(1)Serum ADA level of T1DM patients was higher than that of the healthy control people.T1DM patients with acute diabetes complications had lower serum ADA level compared with T1DM patients with chronic complications.(2)Results of Pearson correlations analysis showed that serum ADA level had positive correlation with fasting blood glucose.(3)Logistic regression analysis showed that the increase of serum ADA level was an independent risk factor in patients with chronic diabetes complications(OR:1.159,95% Cl:1.044~1.286),while it was a protective factor in patients with acute diabetes complications(OR:0.857,95% Cl:0.748~0.981). Conclusions High serum ADA level was observed in type 1 diabetes patients. The serum ADA level was an independent risk factor for T1DM patients with chronic diabetes complications,while it was a protective factor for T1DM patients with acute diabetes complications.
