ABSTRACT
A UPLC-Q-Orbitrap-MS based metabolomic approach combined with biochemical assay and histopathological inspection were employed to study the intervention effects of Suanzaoren Decoction (SZRD) on chronic unpredictable mild stress (CUMS) depression rats, and to clarify the metabolic regulation pathway of SZRD. The rats were randomly divided into normal control group, CUMS model group, positive drug venlafaxine group, SZRD high (24 g·kg-1) and low (12 g·kg-1) dose groups, respectively. The CUMS model was replicated by subjecting to a variety of stimulus, such as thermal stimulation, ice water swimming, ultrasonic stimulation, tail clamping, day and night reversal, plantar electric shock and so on for rats. After oral administration of drugs for 28 days, the behavioral indexes of rats in each group were observed and the hippocampus and serum samples of rats were collected for biochemical assay and histopathological inspection. Compared with the CUMS model group, low dose and high dose SZRD groups can significantly reduce the immobility time of forced swimming (P < 0.001, P < 0.001), increase the sucrose preference rate (P < 0.01, P < 0.05), the number of crossings (P < 0.05, P < 0.01) and the number of uprights (P < 0.05, P < 0.01) in the open field test, suggesting that SZRD can significantly improve the depression-like behavior of CUMS model rats. In addition, SZRD could significantly reduce the levels of serum IL-6, IL-1β and TNF-α of CUMS model rats. A total of 21 differential metabolites in serum were identified by comparison with the data from the literature and databases. In addition, low-dose SZRD and high-dose SZRD improved the 8 and 11 perturbed potential serum biomarkers that were induced by CUMS, respectively, which related to alanine, aspartic acid and glutamic acid, tryptophan and arachidonic acid metabolism. This study provides a scientific basis for expanding the clinical indications of SZRD. This experiment was approved by the Animal Ethics Committee of Shanxi University (Approval No. SXULL2020028).
ABSTRACT
Objective: To explore the relationship of social support to patients with schizophrenia, family burden with patients' quality of life and family life satisfaction. Methods: Multi-stage stratified cluster random sampling was used to select 358 patients with schizophrenia and 358 patients' family members in Gansu Province who met the inclusion criteria were included. The Social Support Rating Scale, Family Burden Scale, Satisfaction with Life Scale and Quality of Life Scale were used in the survey. AMOS 24.0 was used to explore the pathway of influence of family burden on social support to patients with schizophrenia, patients' quality of life and patients' family life satisfaction. Results: There was a two-by-two significant correlation between patients' access to social support, family burden, patients' life quality and family life satisfaction (P<0.05), and the total score of the social support scale negatively predicted the total score of the life quality scale (β=-0.28, P<0.05) and positively predicted the total score of the life satisfaction scale (β=0.52, P<0.05). Family burden was a full mediator between the social support to the patient and the patient's quality of life, and as a partial mediator between the social support to the patient and the family's life satisfaction. Conclusions: Social support to people with schizophrenia is a significant predictor of their quality of life and family life satisfaction. Family burden mediates the relationship of social support to patients with their quality of life and family life satisfaction. Interventions can focus on increasing social support for the patient and reducing the burden on the patient's family to improve the patient's quality of life and increase the satisfaction of the patient's family.

ABSTRACT
@#Objective To explore the influence of applying the fast-track surgery (FTS) to optimize the process in the perioperative period of cardiac intervention on the rehabilitation of patients with radial artery stenting surgery. Methods A total of 190 patients with radial artery stenting surgery in the Department of Cardiology, West China Hospital from June 2017 to May 2018 were enrolled. They were randomized into a control group (n=95) and a FTS group (n=95) by random umber table. There were 60 males and 35 females aged 35-88 (65.2±9.6) years in the control group as well as 62 males and 33 females aged 34-86 (61.5±11.3) years in the FTS group. Patients in the control group received routine perioperative care, but patients in the FTS group received individual precision interventions by applying the FTS concept to optimize the process of perioperative care, including individual care management before being admitted into hospital, during hospital, and after discharge from hospital. Duration of hospital stay, satisfaction scores, number of comorbidities after surgery, disease self-management ability, and readmission rates were compared between the two groups. Results Compared to the control group, the FTS group had significantly shorter duration of hospital stay, less comorbidities, higher satisfaction scores and disease self-management ability, and lower readmission rate to hospital (P<0.05). Conclusion Applying FTS into the perioperative period of cardiac interventions to optimize its process can help patients recover from radial artery stenting surgery, increase patients’ self-management abilities, shorten duration of hospital stay and decrease comorbidities and cardiac adverse events.
ABSTRACT
Objective@#In previous decades, glaucoma has been primarily attributed to elevated intraocular pressure (IOP), but this has gradually been replaced by the development of optic neuropathy as the central concept of glaucoma in developed countries. However, there still remain strong controversies in the definition of glaucoma in China. In this current review, we are going to discuss these controversies and elaborate on the historical transitions of the definition of glaucoma both in China and developed countries. Furthermore, we will briefly describe the "ocular-cranial pressure gradient" theory and discuss the relationship between glaucoma and degenerative diseases of the central nervous system (CNS) in order to show the complex pathogenesis of glaucoma and the importance for the modification to the definition of glaucoma.@*Data Sources@#We performed a comprehensive search in both PubMed and SinoMed using the following keywords: (a) "primary glaucoma" and "guideline," (b) "ocular-cranial pressure gradient," and (c) "glaucoma," "Alzheimer's disease," and "Parkinson's disease." The literature search included the related articles with no restrictions on publication date.@*Study Selection@#The primary references were Chinese and English articles including (a) original guidelines and expert consensuses of primary glaucoma, (b) reviews focusing on the differences between various versions of these guidelines and consensuses, and (c) papers about ocular-cranial pressure gradient theory and the relationship between glaucoma and CNS degenerative diseases.@*Results@#The definitions and classifications of both primary open-angle glaucoma and primary angle-closure glaucoma differ between Chinese glaucoma consensuses and international primary glaucoma guidelines. Chinese definitions and classifications put more emphasis on the IOP, while international guidelines put more emphasis on the presence of optic neuropathy. The ocular-cranial pressure gradient theory and the research on the relationship between glaucoma and CNS degenerative diseases have provided new directions for exploring the pathogenesis of glaucoma.@*Conclusions@#As regards the definition and classification of primary glaucoma, we find that there are still some discrepancies between Chinese expert consensuses and international guidelines. Glaucoma is a disease with complex etiologies, while its common characteristic is a specific optic neuropathy. The current definition and understanding of glaucoma is an ongoing and evolving process, reflecting our latest available evidence on its pathogenesis. Chinese ophthalmology community may need to update our guidelines, accommodating these latest developments.

ABSTRACT
This study explored the association between the lncRNA HOTAIR polymorphism and susceptibility to lead poisoning in a Chinese population. We speculated that lead poisoning caused elevated levels of oxidative stress, which, in turn, activate the HOTAIR gene to cause apoptosis. Three lncRNA HOTAIR tagSNPs (rs7958904, rs4759314, and rs874945) were genotyped by TaqMan genotyping technology in 113 lead-sensitive and 113 lead-resistant Chinese workers exposed to lead. Rs7958904 was significantly associated with susceptibility to lead poisoning (P = 0.047). The rs7958904 G allele had a protective effect compared with the C allele and reduced the risk of lead poisoning (P = 0.016). Rs7958904 may act as a potential biomarker for predicting the risk of lead poisoning and distinguishing lead-sensitive individuals from lead-resistant individuals.

ABSTRACT
The respiratory tract is primary contact site of the body and environment,and it is ventilated by 10-20 thousand liters of air per day.Inevitably,the respiratory system comes into contact with airborne microbes,which contain the disease-causing pathogens.Airway epithelial cells (AECs) are known to have innate sensor functions,which are similar to the "professional" immune cells,such as alveolar macrophage and sub-or intra-epithelial dendritic cells (DCs).Thus AECs are able to detect invading microbial danger including different types of respiratory viruses,and mount a potent host response,for example,activating type Ⅰ interferon signaling pathway genes.To avoid chronic inflammation and maintain the immunological homeostasis,the pulmonary system has developed intrinsic mechanisms to control local immune responses.Most recently,the role of AECs in control of local immunity has gained much attention,as 1) AECs express the pattern recognition receptors (PRRs),such as Toll-like receptors,retinoic acid inducible gene Ⅰ (RIG-Ⅰ)-like receptor,and so on,thus AECs are equipped to Participate in innate detection of microbial encounter;2) To keep immunological homeostasis in the respiratory tract,AECs behave not only as innate immune sensors but also as immune modulators in parallel,through modulating the sensitivity of innate immune sensing of both AECs per se and sub-or intra-epithelial immune cells;3) Loss of modularity capacity of AECs might be involved in the development of chronic airway diseases.In present review,how the AECs act will be intensively discussed in response to respiratory viruses and modulate the local immunity through cis-and trans-factors (direct and indirect factors),as well as the consequence of impairment of this control of local immunity,in the development and exacerbation of airway diseases,such as acute and chronic rhinosinusitis.
ABSTRACT
<p><b>BACKGROUND</b>The effects of near-road pollution on lung function in China have not been well studied. We aimed to investigate the effects of long-term exposure to traffic-related air pollution on lung function, airway inflammation, and respiratory symptoms.</p><p><b>METHODS</b>We enrolled 1003 residents aged 57.96 ± 8.99 years living in the Shichahai Community in Beijing. Distances between home addresses and the nearest major roads were measured to calculate home-road distance. We used the distance categories 1, 2, and 3, representing <100 m, 100-200 m, and >200 m, respectively, as the dose indicator for traffic-related air pollution exposure. Lung function, exhaled breath condensate (EBC) pH, and interleukin 6 levels were measured. As a follow-up, 398 participants had a second lung function assessment about 3 years later, and lung function decline was also examined as an outcome. We used regression analysis to assess the impacts of home-road distance on lung function and respiratory symptoms. As the EBC biomarker data were not normally distributed, we performed correlation analysis between home-road distance categories and EBC biomarkers.</p><p><b>RESULTS</b>Participants living a shorter distance from major roads had lower percentage of predicted value of forced expiratory volume in 1 s (FEV1% -1.54, 95% confidence interval [CI]: -0.20 to -2.89). The odds ratio for chronic cough was 2.54 (95% CI: 1.57-4.10) for category 1 and 1.97 (95% CI: 1.16-3.37) for category 2, compared with category 3. EBC pH was positively correlated with road distance (rank correlation coefficient of Spearman [rs] = 0.176, P < 0.001).</p><p><b>CONCLUSIONS</b>Long-term exposure to traffic-related air pollution in people who live near major roads in Beijing is associated with lower lung function, airway acidification, and a higher prevalence of chronic cough. EBC pH is a potential useful biomarker for evaluating air pollution exposure.</p>

<p><b>BACKGROUND</b>Studies of interleukin (IL)-4 and IL-6 in the exhaled breath condensate (EBC) of asthmatic patients are limited. This study was to determine the effect of inhaled corticosteroid (ICS) treatment on IL-4 and IL-6 in the EBC of asthmatic patients.</p><p><b>METHODS</b>In a prospective, open-label study, budesonide 200 μg twice daily by dry powder inhaler was administered to 23 adult patients with uncontrolled asthma (mean age 42.7 years) for 12 weeks. Changes in asthma scores, lung function parameters (forced expiratory volume in 1 s [FEV1], peak expiratory flow [PEF], forced expiratory flow at 50% of forced vital capacity [FEF50], forced expiratory flow at 75% of forced vital capacity, maximum mid-expiratory flow rate) and the concentrations of IL-4 and IL-6 in EBC were measured.</p><p><b>RESULTS</b>Both asthma scores and lung function parameters were significantly improved by ICS treatment. The mean IL-4 concentration in the EBC was decreased gradually, from 1.92 ± 0.56 pmol/L before treatment to 1.60 ± 0.36 pmol/L after 8 weeks of treatment (P < 0.05) and 1.54 ± 0.81 pmol/L after 12 weeks of treatment (P < 0.01). However, the IL-6 concentration was not significantly decreased. The change in the IL-4 concentration was correlated with improvements in mean FEV1, PEF and FEF50 values (correlation coefficients -0.468, -0.478, and -0.426, respectively).</p><p><b>CONCLUSIONS</b>The concentration of IL-4 in the EBC of asthmatic patients decreased gradually with ICS treatment. Measurement of IL-4 in EBC could be useful to monitor airway inflammation in asthmatics.</p>

PURPOSE: ORM1-like 3 (ORMDL3) belongs to a highly conserved protein family which is anchored as transmembrane protein in the endoplasmic reticulum. Gasdermin B (GSDMB) is adjacent to ORMDL3 on chromosome 17q21.2 and belongs to the gasdermin-domain containing the protein family (GSDM family). Recent reports suggest that GSDMB and ORMDL3 are associated with asthma in several populations. However, genetic association studies that examined the association of GSDMB and ORMDL3 gene variants with asthma showed conflicting results. To assess whether combined evidence shows the association between GSDMB/ORMDL3 polymorphism and asthma. METHODS: A bibliographic search from MEDLINE identified 13 original articles using the search keywords 'GSDMB', 'ORMDL3', and 'asthma'. An updated literature-based meta-analysis involving 6,691 subjects with asthma, 9,281 control individuals, and 1,360 families were conducted. Meta-odds ratios (ORs) and 95% confidence intervals (CIs) based on the fixed effects model or the random effects model depended on Cochran's Q-statistic and I2 values. Data from case-control and TDT studies were analyzed in an allelic model using the Catmap software. RESULTS: We selected and identified 3 SNPs of ORMDL3 associated with asthma (rs8076131: OR=1.10; 95% CI, 1.02-1.20; P=0.012. rs12603332: OR=1.15; 95% CI, 1.05-1.25; P=0.002. rs3744246: OR=1.10; 95% CI, 1.02-1.17; P=0.008) and 1 SNP of GSDMB associated with asthma (rs7216389: OR=1.37; 95% CI, 1.27-1.47; P<0.01). Publication bias was estimated using modified Egger's linear regression test proposed by Harbordetal and revealed no evidence of biases. Furthermore, cumulative meta-analysis in chronological order showed the inclination toward significant association for rs7216389 and rs12603332 with continually adding studies, and the inclination toward null-significant association for rs3744246 and rs8076131. CONCLUSIONS: Moderate evidence exists for associations of the ORMDL3 rs8076131, rs12603332, and rs3744246 and GSDMB rs7216389 variants with asthma. Large sample size and representative population-based studies and TDT studies with homogeneous asthmatic patients and well-matched controls are warranted to confirm this finding.

Objective To discuss the correlation between C-peptide level and autonomic neuropathy in diabetic foot in patients with type 2 diabetes mellitus (T2DM). Methods The levels of fasting blood glucose (FBG), 2 h postprandial blood glucose (2 h-PG) and fasting C-peptide (FC-P) were detected in 124 T2DM patients. The Neuropad was used to test functions of sudomotor nerves in foot. Patients were divided into two groups:diabetic autonomic neuropathy (DAN) group and non-autonomic neuropathy group (NDAN) according to the results of functions of sudomotor nerves in foot. Values of gender, age, body mass index (BMI), blood pressure, FBG, 2 h-PG and FC-P were compared between the two groups. The Pearson correlation analysis was carried out between the indexes mentioned above and the time for completing color change of Neuro-pad. Results There were no significant differences in gender, age, FBG and 2 h-PG between two groups (P>0.05). The FC-P level was (1.07 ± 0.75)nmol/L in DAN group, which was significantly lower than that in NDAN group (1.43 ± 1.00) nmol/L (P > 0.05). The time for completing color change of Neuropad was negatively correlated with C-peptide. Conclu-sion The autonomic nerve functions in diabetic foot is closely related with C-peptide. It is inferred that C-peptide may have protective effect on autonomic nerves in diabetic foot.

<p><b>OBJECTIVE</b>To compare the differences in the efficacy on traumatic spinal cord injury(SCI) in the thoracic and lumbar vertebra between the paraplegia-triple-needling method and the conventional acupuncture therapy.</p><p><b>METHODS</b>The perspectively randomized controlled trial was adopted. Forty-eight cases of traumatic SCI in the thoracic and lumbar vertebra were randomized into an observation group and a control group, 24 cases in each one. The conventional rehabilitation training was applied in both groups. In addition, the paraplegia-triple-needling method was used in the observation group. In the treatment, acupuncture was applied to the points of the Governor Vessel and the Back-shu which, located two segments above and below the spinal injury plane separately. Acupuncture with the electric pulsing stimulation was applied to the motor points of the key muscles of the lower extremities. In the control group, the conventional acupuncture was applied to Huantiao (GB 30), Zusanli (ST 36), Xuanzhong (GB 39) and Sanyinjiao (SP 6). In each group, the treatment was given once a day, one month treatment made 1 session. Totally, 3 sessions of treatment were required. Before and after treatment, as well as in 1-month follow-up visit after treatment, the modified Barthel index (MBI) and the function comprehensive assessment (FCA) were adopted to assess the activities of daily life (ADL) and the comprehensive function of the patients. The score of MBI and FCA were taken as the double response variables to imitate the multilevel model. The changing tendency of MBI and FCA along with the time was observed in two groups.</p><p><b>RESULTS</b>In the follow-up visit, MBI and FCA score were all improved as compared with those before treatment in two groups (all P < 0.05). There were no statistically significant differences in MBI and FCA score at any time point between two groups (all P > 0.05). In 4-month observation, there was a rising tendency with time in MBI and FAC scoe in both groups, which was roughly linear. As time went on, the increasing amplitude in the observation group was much bigger. It was explained that there was no difference in the short-term efficacy between two groups. However, the long-term efficacy in the observation group was much better.</p><p><b>CONCLUSION</b>Both the paraplegia-triple-needling method and the conventional acupuncture therapy can improve the ADL and the comprehensive function of the patients with traumatic SCI of the thoracic and lumbar vertebra. Concerning the long-term efficacy, the paraplegia-triple-needling combined with the rehabilitation training achieves better result. This therapeutic program is safe and effective.</p>

Long circulating paclitaxel microemulsions (TXL-M) were prepared and its anticancer effect was evaluated in metronomic chemotherapy of cancer using animal tumor models. In TXL-M, paclitaxel was dissolved in vitamin E and polyethylene glycol-distearoylphosphatidylethanolamine (PEG-DSPE) was used as surfactant. The shape and particle size distribution of TXL-M were evaluated using an electronic microscope and a laser size scanner. The toxicity comparisons of TXL-M and paclitaxel were conducted using mice. Its anticancer effect and long circulation were evaluated using animal tumor model in C57BL/6 mice. The average diameter of TXL-M was (98.6 +/- 11.2) nm and its zeta potential was (-32.4 +/- 6.8) mV. Compared with paclitaxel, TXL-M showed lower toxicity. When used in metronomic chemotherapy of cancer, TXL-M showed longer circulation time in the blood and greater anticancer effect than paclitaxel. Thus, TXL-M is a better candidate for metronomic chemotherapy of cancer than paclitaxel injection.

Objective To elucidate the important functions of microRNAs (miRNAs) in regulating synaptic assembly and function, we performed a computational analysis for the genetic loci required for the synaptic structure and function and their corresponding miRNAs in C. elegans. Methods Total 198 genetic loci required for the synaptic structure and function were selected. Sequence alignment was combined with E value evaluation to investigate and identify the possible corresponding miRNAs. Results Total 163 genes among the 198 genetic loci selected have their possibly corresponding regulatory miRNA (s), which covered most of the important genetic loci required for the synaptic structure and function. Moreover, only 22 genes among the analyzed 38 genetic loci encoding synaptic proteins have more possibility to under the control of non-coding RNA genes. In addition, the distribution of miRNAs along the 3' untranslated region (UTR) of these 22 genes exhibits different patterns. Conclusion Here we provide the computational screen and analysis results for the genetic loci required for synaptic structure and function and their possible corresponding miRNAs. These data will be useful for the further attempt to systematically determine the roles of miRNAs in synaptic assembly and function regulation in worms.
