Objective To investigate the risk factors for pneumonia complicating infectious mononucleosis(IM)in adults and construct a nomogram prediction model.Methods A retrospective analysis was conducted on 198 IM patients admitted to the Second Affiliated Hospital of Air Force Medical University from January 2015 to December 2021.Patients were divided into pneumonia group(n=52)and non-pneumonia group(n=146)based on whether pulmonary infection occurred during hospitalization.The baseline data(age,gender,place of onset,etc.),clinical manifestations(maximum body temperature,lymph node enlargement,splenomegaly,etc.),and inflammatory indicators[white blood cell count(WBC),C-reactive protein(CRP),etc.]were compared between the two groups.Kaplan-Meier curves were plotted to analyze the key indicators affecting the hospital stay of IM patients.Multivariate logistic regression was used to analyze the independent risk factors for pneumonia complicating IM in adults and construct a nomogram prediction model based on the identified risk factors.The predictive efficacy of the model was evaluated using the receiver operating characteristic(ROC)curve and the consistency of the model was assessed using the calibration curve.The fit of the model was evaluated using the Hosmer-Lemeshow test.Additionally,the sensitivity,specificity,and accuracy of the model were assessed using confusion matrix.Results Compared with non-pneumonia group,the pneumonia group had a significantly higher proportion of patients from rural areas,with body mass index(BMI)≥24 kg/m2,smoking history,hepatomegaly,fever duration of≥7 d,as well as increased total hospitalization costs and average daily hospitalization costs,and prolonged hospital stay(P<0.05).The proportion of patients with a history of antibiotic use was lower in the pneumonia group(P<0.05).Kaplan-Meier survival analysis showed that patients from rural areas,with BMI≥24 kg/m2,smoking history,no prophylactic use of antibiotics,fever duration≥7 d,and hepatomegaly had significantly prolonged hospital stays(P<0.05).Multivariate logistic regression analysis revealed that living in a rural area(OR=4.089,P<0.05),hepatomegaly(OR=4.082,P<0.05),and elevated WBC(OR=1.205,P<0.05)were independent risk factors for pneumonia complicating IM in adults,while the prophylactic use of antibiotics(OR=0.142,P<0.05)was an independent protective factor.The area under the ROC curve of the constructed nomogram prediction model was 0.827(95%CI 0.762-0.892),and the slope of the calibration curve was close to 1,and the Hosmer-Lemeshow test showed χ2=5.299,P=0.725,indicating good consistency and fit of the prediction model.The results of the confusion matrix assessment showed that the sensitivity of the model was 0.669(0.624-0.773),the specificity was 0.827(0.724-0.930),and the accuracy was 0.732(0.665-0.793).Conclusion The nomogram prediction model based on place of onset,hepatomegaly,the prophylactic use of antibiotics and WBC has excellent fit and discrimination,providing an effective quantitative tool for prognosis assessment of IM.

OBJECTIVES: To evaluate the effectiveness of single-balloon and double-balloon enteroscopy in diagnosing pediatric small bowel diseases and assess the diagnostic efficacy of computed tomography enterography (CTE) for small bowel diseases using enteroscopy as the reference standard. METHODS: Clinical data from 576 children who underwent enteroscopy at Hunan Children's Hospital between January 2017 and December 2023 were retrospectively collected. The children were categorized based on enteroscopy type into the single-balloon enteroscopy (SBE) group (n=457) and double-balloon enteroscopy (DBE) group (n=119), and the clinical data were compared between the two groups. The sensitivity and specificity of CTE for diagnosing small bowel diseases were evaluated using enteroscopy results as the standard. RESULTS: Among the 576 children, small bowel lesions were detected by enteroscopy in 274 children (47.6%).There was no significant difference in lesion detection rates or complication rates between the SBE and DBE groups (P>0.05), but the DBE group had deeper insertion, longer procedure time, and higher complete small bowel examination rate (P<0.05). The complication rate during enteroscopy was 4.3% (25/576), with 18 cases (3.1%) of mild complications and 7 cases (1.2%) of severe complications, which improved with symptomatic treatment, surgical, or endoscopic intervention. Among the 412 children who underwent CTE, the sensitivity and specificity for diagnosing small bowel diseases were 44.4% and 71.3%, respectively. CONCLUSIONS SBE and DBE have similar diagnostic efficacy for pediatric small bowel diseases, but DBE is preferred for suspected deep small bowel lesions and comprehensive small bowel examination. Enteroscopy in children demonstrates relatively good overall safety. CTE demonstrates relatively low sensitivity but comparatively high specificity for diagnosing small bowel diseases.

OBJECTIVE To systematically evaluate the efficacy and safety of vonoprazan in the treatment of gastroesophageal reflux disease， and to provide evidence-based reference for clinical drug use. METHODS Randomized controlled trials （RCTs） about vonoprazan （trial group） versus placebo or proton pump inhibitor （control group） were searched in PubMed， the Cochrane Library， Web of Science， CNKI， Wanfang， VIP and CBM databases from the inception to June， 2022. After literature screening and data extraction， the qualities of included literature were evaluated with bias assessment tool recommended by Cochrane system evaluator manual 5.1.0. Meta-analysis， sensitivity analysis and publication bias analysis were conducted by using RevMan 5.4 software. RESULTS A total of 9 RCTs were included， involving 1 882 patients. The results of meta-analysis showed that： total response rate [OR＝1.94，95%CI（1.45，2.58），P＜0.000 01]， cure rate [OR＝2.27，95%CI（1.33，3.86），P＝0.003] and remission rate [OR＝1.81，95%CI（1.28， 2.55）， P＝0.000 7] of trial group were significantly higher than control group； there was no significant difference in the incidence of adverse drug events， diarrhea， nasopharyngitis， upper respiratory tract infection and alkaline phosphatase elevation between two groups （P＞0.05）. The results of subgroup analysis showed that cure rate of trial group was significantly higher than control group at 2 weeks of treatment （P＜0.05）； at 4 and 8 weeks of treatment， there was no significant difference in the cure rate between two groups （P＞0.05）. There was no statistically significant difference in the cure rate between two groups at 2， 4 and 8 weeks of treatment among the patients with Los Angeles grade A/B （P＞0.05）； among the patients with Los Angeles grade C/D， the cure rate of patients in the trial group was significantly higher than control group at 2， 4 and 8 weeks of treatment （P＜0.05）. The results of sensitivity analysis and publication bias analysis showed that the results of this study were robust and the possibility of publication bias was small. CONCLUSIONS Vonoprazan has a considerable effectiveness and safety in the treatment of gastroesophageal reflux disease.

This study evaluated the scientific nature and effectiveness of iterative optimization of prevention and control measures for local outbreaks caused by the BA.2 and BA.5.2 COVID-19 strains in Fujian Province in 2022,to provide a scientif-ic basis for responding to future new or recurrent respiratory infectious diseases.According to the theory of infectious disease dynamics,relevant information regarding the local epidemic situation caused by the BA.2 sub-type Omicron virus strain in March 2022 and BA.5.2 sub-type Omicron virus strain in October 2022 in Fujian Province was collected.The susceptible exposed infectious removed(SEIAR)model of COVID-19 infection with a latent period and asymptomatic infected persons was used to analyze the transmission dynam-ics of two local epidemic situations,and evaluate the preven-tion and control effects.The incubation period of the BA.2 epidemic was 3 days(1～9 days),the intergenerational inter-val was 3 days(1～5 days),and the initial Rt was 3.0(95％CI:2.7～3.3).The incubation period of the BA.5.2 epidemic was 2 days(1～6 days),the intergenerational interval was 1 day(0～2 days),and the initial R,was 1.9(95％CI:1.7～2.1).The fittingresults for the BA.2 and BA.5.2 epidemics were good,and no statistical difference was observed between the predic-ted and actual numbers of cases(x2BA.2=31.53,x2BA.5.2=27.88,P＞0.05).If an emergency response had not been initiated,the BA.2 epidemic would have continued to spread andpeak on April 7th,with an estimated 638 035 cases.The BA.5.2 epidemic would have rapidly spread,reaching a peak on November 14th,with an estimated 685 940 cases.If one incubation period were detected early,the scale of the BA.2 epidemic would have decreased by 25.73％;if two incubation periods were detected early,the scale would have decreased by 79.56％,and if one incubation period had been delayed,the scale would have expanded by 13.72％.If one incubation period had been detected early in the BA.5.2 epidemic,the scale would have decreased by 35.04％;if two incubation periods had been detected early,the scale would have decreased by 92.47％;and if one incubation period had been delayed,the scale would have increased by 19.75％.The guiding ideology,and the prevention and control measures for handling two local epidemics were optimized and iterated.Our study indicated that implementing the"four early"measures ef-fectively decreased the scale of the epidemic,and earlier detection was associated with more significant control effects.This study provides valuable information for the prevention and control of new or recurrent respiratory infectious diseases.

OBJECTIVES: To study the clinical features of intestinal polyps and the risk factors for secondary intussusception in children. METHODS: A retrospective analysis was performed for the medical data of 2 669 children with intestinal polyps. According to the presence or absence of secondary intussusception, they were divided into two groups: intussusception (n=346) and non-intussusception (n=2 323). Related medical data were compared between the two groups. The multivariate logistic regression analysis was used to identify the risk factors for secondary intussusception. RESULTS: Among the children with intestinal polyps, 62.42% were preschool children, and the male/female ratio was 2.08∶1; 92.66% had hematochezia as disease onset, and 94.34% had left colonic polyps and rectal polyps. There were 346 cases of secondary intussusception, with an incidence rate of 12.96% (346/2 669). Large polyps (OR=1.644, P<0.001), multiple polyps (≥2) (OR=6.034, P<0.001), and lobulated polyps (OR=93.801, P<0.001) were the risk factors for secondary intussusception. CONCLUSIONS Intestinal polyps in children often occur in preschool age, mostly in boys, and most of the children have hematochezia as disease onset, with the predilection sites of the left colon and the rectum. Larger polyps, multiple polyps, and lobulated polyps may increase the risk of secondary intussusception, and endoscopic intervention is needed as early as possible to improve prognosis.

In this paper， the name， classification， origin and other aspects of Schizonepetae Herba in the famous classical formulas were researched by referring to the related herbal literature， medical books and prescription books in the past dynasties. The results showed that Schizonepetae Herba first appeared in Shennong Bencaojing （《神农本草经》） as Jiasu， while Jingjie first appeared in Wupu Bencao （《吴普本草》）， and the name of Jingjie was mainly used as the rectification of name in later generations. The name of Jiasu is mostly derived from its smell， and the name of Jingjie is mostly derived from its pronunciation. Schizonepeta tenuifolia has been highly praised in the past as a original material， and its genuine producing area is Jiangsu， Hebei and other places， medicinal part is whole herb with spike. In modern times， the quality of Schizonepetae Herba is best described as having thin stems， green spike， and aroma. In clinical application， the raw products of Schizonepetae Herba is mainly used， and the carbonisata is mainly used for hemostasis. Famous classical formulas of Huaihuasan and Danggui Yinzi are all made of Schizonepetae Spica， so it is recommended to use the dried panicle of S. tenuifolia. In Liangxue Dihuangtang， Schizonepetae Herba Carbonisata is used， therefore， it is suggested to adopt the processing method of Schizonepetae Herba Carbonisata in the 2020 edition of Chinese Pharmacopoeia.

BACKGROUND: Treatment of coronary bifurcation lesions remains challenging; a simple strategy has been preferred as of late, but the disadvantage is ostium stenosis or even occlusion of the side branch (SB). Only a few single-center studies investigating the combination of a drug-eluting stent in the main branch followed by a drug-eluting balloon in the SB have been reported. This prospective, multicenter, randomized study aimed to investigate the safety and efficacy of a paclitaxel-eluting balloon (PEB) compared with regular balloon angioplasty (BA) in the treatment of non-left main coronary artery bifurcation lesions. METHODS: Between December 2014 and November 2015, a total of 222 consecutive patients with bifurcation lesions were enrolled in this study at ten Chinese centers. Patients were randomly allocated at a 1:1 ratio to a PEB group (n = 113) and a BA group (n = 109). The primary efficacy endpoint was angiographic target lesion stenosis at 9 months. Secondary efficacy and safety endpoints included target lesion revascularization, target vessel revascularization, target lesion failure, major adverse cardiac and cerebral events (MACCEs), all-cause death, cardiac death, non-fatal myocardial infarction, and thrombosis in target lesions. The main analyses performed in this clinical trial included case shedding analysis, base-value equilibrium analysis, effectiveness analysis, and safety analysis. SAS version 9.4 was used for the statistical analyses. RESULTS: At the 9-month angiographic follow-up, the difference in the primary efficacy endpoint of target lesion stenosis between the PEB (28.7% ± 18.7%) and BA groups (40.0% ± 19.0%) was -11.3% (95% confidence interval: -16.3% to -6.3%, Psuperiority <0.0001) in the intention-to-treat analysis, and similar results were recorded in the per-protocol analysis, demonstrating the superiority of PEB to BA. Late lumen loss was significantly lower in the PEB group than in the BA group (-0.06 ± 0.32 vs. 0.18 ± 0.34 mm, P < 0.0001). For intention-to-treat, there were no significant differences between PEB and BA in the 9-month percentages of MACCEs (0.9% vs. 3.7%, P = 0.16) or non-fatal myocardial infarctions (0 vs. 0.9%, P = 0.49). There were no clinical events of target lesion revascularization, target vessel revascularization, target lesion failure, all-cause death, cardiac death or target lesion thrombosis in either group. CONCLUSIONS: In de novo non-left main coronary artery bifurcations treated with provisional T stenting, SB dilation with the PEB group demonstrated better angiographic results than treatment with regular BA at the 9-month follow-up in terms of reduced target lesion stenosis.

OBJECTIVE: To follow up the participants of the randomized clinical trial "Efficacy and Safety of Niaoduqing Particles () for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction. METHODS: Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks (146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) after completion of the open-label treatment period. RESULTS: After the double-blind period, the median (interquartile range) changes in Scr were 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) μmol/L for the Niaoduqing Particle and placebo groups, respectively (P=0.008), and the median changes in eGFRs were-0.2 (-4.3-2.7) and-2.21 (-5.7-0.8) mL•min•1.73 m, respectively (P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0 (-10.0-41.9) and 17.5 (-6.0-50.0) μmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively (P=0.214), and the median changes in eGFRs were-2.3 (-6.4-1.9) and-3.7 (-7.5-1.1) mL•min•1.73 m, respectively (P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 mL•min•1.73 m per year. CONCLUSION Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function. (Trial registration No. ChiCTR-TRC-12002448).

Objective: To establish real-time recombinase polymerase amplification（RPA）for the rapid detection of Vibrio parahaemolyticus（VP）. Methods: An exo probe and primers were designed according to the conserved sequence of thermolabile hemolysin（tlh）gene of VP and then RPA for detection of VP was established. The sensitivity of the assay was evaluated by detecting different concentration of VP;the specificity was evaluated by detecting different bacteria;the stability was evaluated by repeat trials;the application effect was evaluated by detecting food samples which were simultaneously tested with traditional culture method according to GB 4798.7-2013 Detection of VP. Results: A real-time RPA was established to complete VP amplification within 20 min at a constant temperature of 39 ℃. The analytical sensitivity of the assay was five pg per reaction and no cross-reactivity with other pathogenic bacteria observed. The RPA detection results with different concentration of VP and E. coli DNA templates at three time points were consistent. The detection results of 51 food samples by RPA were the same as those by traditional culture method. Conclusion The established real-time RPA can qualitatively detect VP,with simple operation and interpretation of results,which is suitable for rapid detection of VP in public health emergencies and food safety supervision.

AIM:To study the effect of ClC-3 gene over-expression on thyroid structure and function in mice. METHODS:Three-months-old FVB mice were used to study the difference of thyroid structure and function between wild-type(WT)mouse and ClC-3 transgene mice.The expression and distribution of ClC-3 in the thyroid of mice were deter-mined by the methods of qPCR,Western blot and immunofluorescence.Behavioral monitoring was performed on the daily activities of mice.Serum concentrations of total triiodothyronine(TT3), total thyroxine(TT4)and thyrotropin(TSH) were measured by ELISA.RESULTS:Compared with the WT group,the expression of ClC-3 in the thyroid of ClC-3 trans-gene group was significantly increased(P<0.05).The thyroid gland showed obvious hyperplasia and the folliculi glandu-lae thyreoideae was significantly bigger in ClC-3 transgene mice(P<0.05).The weight loss was increased in ClC-3 trans-gene mice(P<0.05).The expression of TT3 and TT4 were significantly higher than that of WT group(P<0.05),but the change of TSH was not obvious.CONCLUSION:ClC-3 over-expression results in thyroid hyperplasia and thyroid hor-mone secretion.This study suggests that ClC-3 is likely to be involved in the synthesis of thyroid hormones.
