The tuberous roots of Aconitum carmichaeli are largely used in traditional Chinese medicine and widely grown in Jiangyou, Sichuan, China. During the growth process, this medicinal plant releases a large amount of allelochemicals into soil, which retard the growth and development of near and late crops. Therefore, a pure culture experiment was thus carried out by seed soaking to study the allelopathic effects of extracts from tuberous roots of A. carmichaeli (ETR) on the seed germination and young seedling growth of Lolium perenne, Trifolium repens, and Medicago sativa, the late pasture grasses after cultivation of A. carmichaeli. The results showed that three pasture grasses varied significantly in seed germination and young seedling growth in response to ETR concentrations. Seed germination of M. sativa was stimulated by low ERT concentration (0.01 x g(-1)), while all of pasture grass seeds germinated poorly in solution with 1.00 g x L(-1). Seed soaking with 1.00 g x L(-1) also inhibited significantly the growth of pasture young seedlings, with M. sativa showing the highest seedling height reduction of 42.05% in seeding height, followed by T. repens (40.21%) and L. perenne with about 11%. Cultivation of L. perenne could thus be beneficial to increase whole land productivity in A. carmichaeli-pasture grass cropping systems. In addition, hydrolysis of protein, starch, and inositol phosphates was blocked and free amino acids, soluble sugars and phosphorus were decreased in seeds by seed soaking with ETR, which could be one of the reason for the inhibition of seed germination. There was a significant reduction in root vigor, nitrate reductase, and chlorophyll after the seed treatment with ETR, indicating the suppression of nutrient uptake, nitrate assimilation, and photosynthesis by allelopathic chemicals in ETR, which could lead to the slow growth rate of pasture grass seedlings.

Objective • To examine quality of life and its influencing factors in patients over 12 months after diagnosis of non-small cell lung cancer (NSCLC). Methods • A total of 111 patients included in the study completed the self-reported measures. Quality of life was measured using Functional Assessment of Cancer Therapy-Lung. Other measures included socio-demographic characteristics, disease- and treatment-related information, and emotional feelings. Results • The factors influencing the quality of life of NSCLC patients were investigated from two approaches: treatment and subjective feeling. Univariate Logistic regression analysis found the risk factors for low quality of life included sense of low self-esteem and loneliness, bone metastasis, pathological type, chemotherapy cycle, age, cohabitant type and financial burden. Conclusion • The factors associated with quality of life in lung cancer patients are diverse and extensive, and it warrants attention on psychological support and symptom management for these patients.

Abstract: Objective　To establish a risk prediction model for nosocomial infection in preterm very low birth weight infants, and conduct internal validation. Methods　A total of 206 cases of very low birth weight premature infants hospitalized in the Department of Neonatology of Union Hospital Affiliated to Tongji Medical College from January 2018 to June 2020 were included in this study, factors that may affect the nosocomial infection of children were collected, and the infants were divided into two groups according to whether there is nosocomial infection. The influencing factors were compared between the two groups, and multivariate Logistic regression analysis was performed after screening variables with LASSO regression. According to the results of multi factor analysis, the nomogram model was constructed and verified internally. Results　A total of 29 of 206 children had nosocomial infection (14.08%), and 33 pathogenic bacteria were detected, including 23 Gram-negative bacteria, 9 Gram-positive bacteria and 1 fungus. The results of multivariate logistic regression analysis based on LASSO regression showed that the risk factors for nosocomial infection of VLBW premature infants were 28-31+6 weeks of gestation, amniotic fluid pollution, mechanical ventilation, indwelling gastric tube, unreasonable use of antibiotics, and hospitalization time ≥ 7 days. The protective factors were Apgar score ≥ 7 points at 1 min and breast feeding accounting for 50% or more (P<0.05). The Area Under Curve (AUC) of ROC curve of nomogram model was 0.946 [95%CI(0.923, 1.000)]. The calibration curve showed that the probability of hospital infection predicted by the model was basically consistent with the actual probability. The decision curve showed that when the probability threshold of nomogram model to predict the risk of nosocomial infection of very low birth weight premature infants was 0-0.85, the net rate of return was greater than 0. Conclusion　Preterm infants with extremely low birth weight are at high risk of nosocomial infection, mainly affected by factors such as gestational weeks, hospitalization time, amniotic fluid pollution, etc. The nomogram model constructed by the above factors has high accuracy and discrimination for predicting nosocomial infection in such children.

AIM: To explore the long-term efficacy of Q-factor guided laser epithelial keratomleusis ( LASEK ) for myopia and astigmatism with positive Q-factor.
METHODS: There were 158 eyes which were myopia and astigmatism with positive Q- factor taken in two groups randomly: 86 eyes accepted Q - factor guided LASEK as observation group and 72 eyes accepted routine LASEK as control group. The difference between the two groups about all data was similar. The uncorrected visual acuity ( UCVA ) and the best corrected visual acuity ( BCVA ) as well as diopter, ocular tension, corneal topography, Keratometry value K, aspherical factor Q, Higher-order aberrations ( HOA ) , corneal thickness by ultrasound and, contrast sensitivity ( CS ) , Haze were examined and compared before and after surgery. All the cased were followed up for 14d, 1, 3, 6, 12mo. And there were no statistical difference among the data before surgery.
RESULTS: After 12mo there were no statistical difference between the two groups about UCVA and BCVA. But the safety index of observation group was 1.10, that of control group was 1. 07. The validity index of observation group was 1. 06, that of control group was 0.99. The HOA of observation group was 0. 45±0. 17μm, and that of control group was 0. 72±0.25μm, there was statistically significant difference (t=-8. 193,P=0. 000). Q factor of observation group was 0. 41±0. 17, that of control group was 0. 77±0. 22, there was significant difference (t=11. 377,P = 0. 028). The contrast sensitivity of 3mo post surgery of patients in the observation group returned to the level of before surgery. But in the control group the contrast sensitivity of the patients did not returned until 6mo.
CONCLUSION:Q-factor guided LASEK for myopia and astigmatism with positive Q-factor is stable, safe and effective. The operation allow for reducing the high order aberrations, maintaining the most asphericity of cornea, saving more in corneal tissue, which cause faster recovery of contrast sensitivity, less haze and better visual quality.

Eosinophilic gastroenteritis (EGE) is a rare chronic disease of digestive system, characterized by the eosinophil infiltration of the gastrointestinal tract and the thickening of the gastrointestinal wall. At present, the etiology and pathogenesis of EGE are still unclear. Accompanied with eosinophilia and elevation of serum immunoglobulin E, the clinical manifestations of EGE are dependent on the location of lesions and the extent or depth of eosinophil infiltration in the gastrointestinal tract. The thickening or edema of the gastrointestinal wall, nodular-like changes, intestinal stenosis and ascites can be regarded as common radiological findings of EGE, while erythema, hyperemia or edema, erosion and ulcer of mucosal are the endoscopic features of EGE. Tissue biopsy is helpful for the diagnosis of EGE. However, with unspecific clinical manifestations, laboratory tests, radiological and endoscopic findings and unidentified cut-off count of pathological diagnostic criteria, EGE is very difficult to be diagnosed. Therefore, this paper mainly reviews the research progress in the diagnosis and treatment of EGE, attempting to improve the clinicians' understanding of EGE.

The treatment and signaling pathway regulation effects of kidney- tonifying traditional Chinese medicine on osteoporosis have been widely studied, but without a systematic summary currently. This review comprehensively collected and analyzed the traditional Chinese medicine on the treatment and signaling pathway regulation of osteoporosis in recent ten years, such as Epimedium, Drynariae Rhizoma, Cnidium, Eucommia, Psoralen and Dipsacus. Based on the existing findings, we concluded the following conclusions: (1) kidney-tonifying traditional Chinese medicine treats osteoporosis mainly through BMP-Smads, Wnt/β-catenin, MAPK, PI3K/AKT signaling pathway to promote osteoblast bone formation and through OPG/RANKL/RANK, estrogen, CTSK signaling pathway to inhibit osteo?clasts of bone resorption. ① Epimedium, Drynariae Rhizoma, Cnidium and Psoralen up-regulate the key proteins and genes of BMP-Smads and Wnt/β-catenin signaling pathways to promote bone formation.② Epimedium, Drynariae Rhizoma, Cnidium, Eucommia, Psoralen, Dipsacusinhibit the bone resorption by mediating the OPG/RANKL/RANK signaling pathway. (2) Kidney-tonifying traditional Chinese medicine prevent and treat osteoporosis through a variety of ways: Icariin, Naringin, Osthol, Psoralen can regulate BMP-Smads, Wnt/β-catenin signaling pathway to promote bone formation, but also activate OPG/RANKL/RANK, CTSK and other signaling pathway to inhibit bone resorption. (3) The crosstalk of the signaling pathways and the animal experiments of the traditional Chinese medicine on the prevention and treatment of osteoporosis as well as their multi-target mechanism and comprehensive regulation need further clarification.
