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.

Conversion therapy such as transcatheter arterial chemoembolization(TACE)and hepatic arterial infusion chemotherapy(HAIC)is the main treatment method to transform unresectable advanced liver cancer into resectable liver cancer,which can not only effectively increase the survival rate of patients,but also provide patients with the opportunity of liver transplantation.However,pain is a major complication of TACE and HAIC in the treatment of liver cancer,and the incidence of abdominal pain after TACE is from 19.3%to 71.2%,and nearly 64.6%of patients have different degrees of pain during HAIC,which seriously affects the quality of life of patients and shortens their survival time.At present,the mechanism of pains caused by TACE and HAIC is not clear,and it may be related to local liver tissue swelling after embolic agents block the tumor blood supply artery,increased pressure in the liver tissue envelope or traction of the mass capsule,chemical stimulation of the hepatic artery by embolic agents and antineoplastic drugs,thrombosis adjacent to the normal organs,and visceral pain sensitization caused by intestinal ischemia.There are two main intervention measures for pain,one of which is lidocaine,opioids,non-steroidal anti-inflammatory drugs and glucocorticoids,and the other is wrist and ankle acupuncture and traditional Chinese medicine decoction,but their treatment effects are uneven.This article summarizes the status and treatment of pain caused by TACE and HAIC therapies for liver cancer,in order to provide reference for its clinical treatment.

Objective: To explore the trend and influencing factors of serum lipoprotein (a) (Lp(a)) concentration over time in Chinese community populations. Methods: This study is a prospective cohort study. The participants were enrolled from Chinese Multi-provincial Cohort Study- Beijing projects, completed the cardiovascular disease risk factor surveys in 2002 and 2007, and the serum Lp (a) concentration were measured. Based on the Lp(a) concentration at baseline (2002) and follow-up (2007), the participants were classified into subgroups of <30.0 mg/dl (1 mg/dl=0.01 g/L) group, 30.0 to 49.9 mg/dl group, and ≥50.0 mg/dl group, respectively. Multivariable logistic regression analysis was used to identify influencing factors associated with Lp (a) absolute change (≥20 mg/dl) and relative change (≥20%) within 5 years. Results: Among 1 955 participants with age of (56.5±8.0) years old and 821 male (42.0%) at baseline, there were 1 657 (84.8%), 184 (9.4%) and 114 (5.8%) participants in Lp(a)<30.0 mg/dl group, 30.0 to 49.9 mg/dl group and ≥50.0 mg/dl group, respectively. Among the baseline Lp(a) concentration of 30.0-49.9 mg/dl group, 68 (37.0%) participants progressed to Lp(a) ≥50.0 mg/dl after 5 years follow-up, and 102 (55.4%) remained at this level. Participants with baseline Lp(a)<30.0 mg/dl (92%, 1 524/1 657) or Lp(a)≥50.0 mg/dl (94.7%, 108/114) tended to be maintained at their respective levels. The results of the multivariate logistic regression analysis showed that, in addition to the high level of baseline Lp(a) concentration, family history of cardiovascular disease, elevated fasting blood glucose and usage of oral lipid-lowering drugs were the influencing factors of Lp(a) changes over time (P<0.05). Conclusions: Adults with borderline-high Lp(a) concentrations (30.0 to 49.9 mg/dl) could be considered for repeated testing, especially for those with a family history of cardiovascular disease, elevated fasting blood glucose and usage of statins.

Obvious epigenetic differentiation occurred on Lycium barbarum in different cultivation areas in China. To investigate the difference and change rule of DNA methylation level and pattern of L. barbarum from different cultivation areas in China, the present study employed fluorescence-assisted methylation-sensitive amplified polymorphism(MSAP) to analyze the methylation level and polymorphism of 53 genomic DNA samples from Yinchuan Plain in Ningxia, Bayannur city in Inner Mongolia, Jingyuan county and Yumen city in Gansu, Delingha city in Qinghai, and Jinghe county in Xinjiang. The MSAP technical system suitable for the methylation analysis of L. barbarum genomic DNA was established and ten pairs of selective primers were selected. Among amplified 5'-CCGG-3' methylated sites, there were 35.85% full-methylated sites and 39.88% hemi-methylated sites, showing a high degree of epigenetic differentiation. Stoichiometric analysis showed that the ecological environment was the main factor affecting the epigenetic characteristics of L. barbarum, followed by cultivated varieties. Precipitation, air temperature, and soil pH were the main ecological factors affecting DNA methylation in different areas. This study provided a theoretical basis for the analysis of the epigenetic mechanism of L. barbarum to adapt to the diffe-rent ecological environments and research ideas for the introduction, cultivation, and germplasm traceability of L. barbarum.

The fruit of Lycium barbarum L. (FLB) is a food and medicinal herb. Identifying suitable production regions for this plant would be beneficial to its cultivation and production. In this study, the Maxent model was used to identify ecologically suitable regions for the growth of L. barbarum L. In addition, based on its chemical composition, the suitable regions for production were identified by literature analysis and chemometrics. The results show that suitable regions for L. barbarum L. culture are mainly distributed in the northwest of China; suitable regions for the production of medicinal FLB were mainly concentrated in the district of Ningxia, Baiyin, Jiuquan and Zhangye of Gansu, and parts district in west of Inner Mongolia. All are the traditional production regions for FLB, which is consistent with the good quality of FLB produced in Ganzhou in ancient times, and the genuine medicinal materials of FLB produced in Zhongning of Ningxia today. The suitable regions for edible FLB were mainly distributed in northwest of Qinghai, Jiuquan and Zhangye of Gansu, as well as Aksu and Kizi sukirgiz of Xinjiang. The fruit type index of FLB in these regions is large, and the content of fructose and glucose in the fruit is high, which satisfies the edible commodity property. The study results lay a foundation for realizing the regional distribution and development of L. barbarum based on its different uses.

Through investigation,it was found that the main disease of leaves was grey mold on Dendrobium officinale in Hubei province,which has a great impact on the yield and quality of D. officinale. The identification of morphological and molecular biological was used to prove that the pathogen was Botrytis cinerea. Through test the effect of 5 plant source fungicides and 4 antibiotic fungicides on mycelial growth of strain HS1,which proved 0. 3% eugenol had the best inhibitory effect,EC50 was 0. 29 mg·L^-1,the second was1% osthol and EC50 was 1. 12 mg·L^-1,the EC50 of 0. 5% matrine was 9. 16 mg·L^-1,the EC50 of the other six fungicides was higher than 10 mg·L^-1. The field control effect test proved that 0. 3% eugenol had the best control effect,reaching 89. 44%,secondly for 1%osthole,which was 77. 17%,0. 5% matrine was in the third place with 62. 37% of effective rate. However,the control effect of the other fungicides was less than 60%. The three plant-derived fungicides were safe for the produce of D. officinale and showed no phytotoxicity. The effect of these fungicides on the growth of D. candidum was tested,and proved that all the fungicides were safe and harmless to D. candidum. This study provides a research basis for the safe and effective prevention and control gray mold of D. officinale.

Objective To investigate the clinical efficacy of kinetic rectification acupuncture in treating acute facial neuritis. Method Sixty patients with acute facial neuritis were randomized to observation and control groups. The observation group received kinetic rectification acupuncture and the control group, conventional acupuncture alone. Acupuncture was given five times a week, five times as one course. The therapeutic effects were evaluated after three courses of treatment. Result The total efficacy rate was 93.3% in the observation group and 73.3% in the control group; there was a statistically significant difference between the two groups (P<0.05). The latencies and amplitudes of the frontal muscle, orbicularis oculi muscle and quadrate muscle of upper lip improved in the two groups after treatment and had statistically significant pre-/post-treatment differences (P < 0.01). There were statistically significant differences in the pre-/post-treatment difference values of the latencies and amplitudes of the frontal muscle and orbicularis oculi muscle (P<0.01) and no statistically significant difference in the pre-/post-treatment difference values of the latency and amplitude of the quadrate muscle of upper lip (P>0.05) between the two groups. Conclusion Kinetic rectification acupuncture has a marked therapeutic effect on acute facial neuritis. This study provides a particular therapeutic method for clinical practice.

AIM To investigate the effects of Shenge Powder (Ginseng Radix et Rhizoma,Gecko) on heart function in rats with heart failure by coarctation of abdominal aorta and its mechanism of action.METHODS The heart failure rats were fed with Shenge Powder [1.89 g/(kg · d)] or bisoprolol [1 mg/(kg · d)] for twelve weeks.The pathological morphology,hemodynamics,cardiographic index and effect on protein expression of PGC-1 α in sham operation group,model group,Shenge Powder group and Bisoprolol group were observed.RESULTS Compared with the model group,Shenge Powder increased ejection fraction (EF) (P ＜ 0.05),decreased left ventricular end-diastolic pressure (LVEDP) (P ＜ 0.01),improved maximal rate of left ventricular pressure development (dp/dtmax) and maximal rate of left ventricular pressure decay (dp/dtmin) (P ＜ 0.01),reduced myocardial tissue lesions and myocardial fibrosis.There was no significant difference in PGC-1α protein expression between the Shenge Powder group and the model group.CONCLUSION Shenge Powder can improve left ventricular function in rats with heart failure,and reduce the pathological changes of myocardium tissue.

OBJECTIVETo investigate the viral etiology in hospitalized children with acute lower respiratory tract infections (ALRTI) plus platelet disorders.

METHODSA total of 255 children with ALRTI plus platelet disorders and 442 children with ALRTI and normal platelets, all of whom were hospitalized between March 2010 and February 2011, were included in the study. Their nasopharyngeal aspirate samples were collected, and RT-PCR or PCR was performed to detect 14 viruses.

RESULTSOf 255 ALRTI patients with platelet disorders, thrombocytosis was found in 253 cases (99.2%) and thrombocytopenia in 2 cases (0.8%). Among ALRTI patients with platelet disorders, 173 (67.8%) were infected with at least one virus, with human rhinovirus as the most common one, followed by parainfluenza virus type 3 (PIV3) and respiratory syncytial virus (RSV). The detection rate of PIV3 in the abnormal platelet group was significantly higher than in the normal platelet group (P<0.05). In contrast, the detection rate of influenza virus B (IFVB) in the abonormal platelet group was significantly lower than in the normal platelet group (P<0.05). The age distribution showed significant difference between the abnormal and normal platelet groups (P<0.01). Platelet disorders were mainly found in children under one year of age (P<0.01).

CONCLUSIONSThrombocytosis is often found in children with ALRTI caused by viruses, especially PIV3, but infection with IFVB seldom causes platelet disorders. Hospitalized children with ALRTI under one year tend to develop platelet disorders.
