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.

OBJECTIVE@#To analyze the clinical characteristics of venous thromboembolism (VTE) in patients with multiple myeloma (MM) and to identify the risk factors of VTE in MM patients.@*METHODS@#179 newly diagnosed MM (NDMM) patients admitted to The Second Hospital of Shanxi Medical University from January 2014 to December 2020 who were followed up for more than 6 months were collected, and they were divided into VTE group and control group according to whether combined with VTE. The clinical and laboratory data were compared between the two groups. Mann-whitney U test was used for inter-group comparison of measurement data, Chi-square test or Fisher's exact test was used for inter-group comparison of count data, and multivariate logistic regression analysis was performed to explore the risk factors of VTE in MM patients.@*RESULTS@#Compared with control group, the serum albumin (ALB) level in VTE group was significantly lower (P =0.033), the fibrinogen (FIB) level was significantly higher (P =0.016), and the proportion of patients with D-dimer≥2 000 ng/ml was significantly higher than that in the control group (26.3% vs 4.4%, P =0.002). There was a significant difference in M-component type between the two groups (P =0.028), and the proportion of IgG type in VTE group was higher. There were no statistically significant differences between two groups in age, sex, body mass index (BMI), the proportions of patients with hypertension, diabetes, coronary heart disease and cerebral infarction, white blood cell (WBC) count, platelet (PLT) count, liver and kidney function, plasma cells ratio in bone marrow, serum globulin (GLO), lactate dehydrogenase (LDH), β2-microglobulin (β2-MG) level, C-reactive protein (CRP) level, erythrocyte sedimentation rate (ESR), prothrombin time (PT), activated partial thromboplastin time (APTT), disease stage, thrombosis prevention and the use of immunomodulators (P >0.05). Multivariate logistic regression analysis showed that FIB level (OR=1.578, 95%CI:1.035-2.407, P =0.034), D-dimer≥2 000 ng/ml (OR=5.467, 95%CI:1.265-23.621, P =0.023) and IgG type (OR=4.780, 95%CI: 1.221-18.712, P =0.025) were independent risk factors for VTE in MM patients.@*CONCLUSION@#MM patients are prone to VTE, and FIB level, D-dimer≥2 000 ng/ ml and IgG type are independent risk factors for VTE in MM patients.

Resveratrol (RES) can inhibit the growth and proliferation of liver cancer cells. However, its role in the precancerous stage is still unclear. This paper aims to study the effect and mechanism of RES on the precancerous stage of liver cancer in rats induced by diethylinitrosamine (DEN). SD rats were divided into normal control group, RES treatment group, DEN treatment group and RES-DEN treatment group. The results showed that after the rats were treated with DEN for 8 weeks, the total expression level of proliferating cell nuclear antigen (PCNA) of hepatocytes increased to 2-fold (P<0.05), and the expression level of PCNA protein in the nucleus increased to 3-fold (P<0.001). However, the expression levels of total PCNA (P<0.05) and nuclear PCNA protein (P<0.001) in hepatocytes of rats treated with RES-DEN decreased, suggesting that RES could significantly inhibit the liver malignant proliferation of cells. Through non-targeted metabolomics and KEGG metabolic pathway enrichment analysis, the results showed that the level of glycolysis did not increase significantly in the hepatocytes of RES-DEN-treated rats, although the transition from the pentose phosphate pathway to the glycolysis pathway was enhanced when compared with the DEN group rats. This finding suggested that the metabolic pathway of phosphoenolpyruvate-pyruvate-lactate was inhibited. Further verification found that the protein expression levels of key enzymes M2-type pyruvate kinase (PKM2) and lactate dehydrogenase (LDHA) in this metabolic pathway were inhibited (P<0.05). RES can reprogram glucose metabolism and inhibit DEN-induced excessive proliferation of rat hepatocytes in the precancerous stage of liver cancer, providing an experimental basis for RES to prevent liver cancer.
ABSTRACT
The new ultrasound device, automated breast ultrasound (ABUS), has the advantages of repeatable reading of standardized whole breast images, and can separate ultrasound scanning and diagnosis. ABUS is more suitable for breast ultrasound training. This study compared the breast ultrasound imaging training model with ABUS diagnosis practice as the core and the traditional breast ultrasound imaging training model with handhold ultrasound operation and diagnosis as the core, and found that the new training model with ABUS diagnosis practice as the core had a short training period. The diagnostic level of doctors have improved rapidly, and the new training model could efficiently train more technically qualified ultrasound doctors for breast disease.

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.

Objective To explore the protective effects of short-acting β31 receptor blocker esmolol on lung injury in septic rats and explore its mechanism.Methods Fifty-four male SpragueDawley rats were randomly(random number) divided into three groups (n=18 in each),namely sham operation group(Sham),sepsis group(Spesis),esmolol group(ES).Each group were further divided into three subgroups of 6 h,12 h and 24 h(n=6 in each subgroup).The sepsis models were established with cecal ligation and puncture (CLP) in rats of Sepsis group and ES group,while rats of SH group were treated with laparotomy without CLP.Dwelled cannulation in the left internal jugular vein was performed after the model establishment.Saline in the rate of 1 mL/h was continuously pumped intravenously into the rats of SH group and Sepsis group by micro pump for 6 h,and esmolol solution in the rate of 1 mL/h [15 mg/(kg·h)]was continuously pumped into the rats of ES group for 6h.Rats in each subgroup were sacrificed at 6h,12h and 24 h after modeling,separately.The levels of catecholamine (CA) in plasma and levels of NF-κB in lung tissue were measured by ELISA.The protein levels of TLR4 and NF-κB in lung tissue were detected by Western Blot.The protein content of alveolar lavage fluid,wet/dry weight ratio(W/D) of lung tissue,lung coefficient and lung water content were measured.The pathological changes of lung tissues were observed under an optical microscope.Results (①) The levels of CA in plasma in Sepsis and ES groups at 6 h after modeling was significantly increased compared with Sham group (P<0.05),and the level of CA in plasma increased significantly in ES group compared with Sham and Sepsis groups (P<0.05).At 12 h after modeling,level of CA in plasma was still significantly increased in ES group compared with SH group (P<0.05);At 24 h after modeling,level of CA in plasma was increased significantly in ES group compared with Sepsis group (P<0.05).(②) At 6 h,12 h and 24 h after modeling,levels ofNF-κ B in lung tissue were significantly increased in Sepsis group and ES group compared with SH group (P<0.05),and levels of NFκ B in lung tissue in ES group were also significantly lower than those in Sepsis group at given intervals (P<0.05).③ At 6 h,12 h and 24 h after modeling,protein content of alveolar lavage fluid,wet/dry weight ratio (W/D) in lung tissue,lung coefficient and lung water content in Sepsis group and ES group were significantly increased compared with SH group (P<0.05),and protein content of alveolar lavage fluid,wet/ dry weight ratio (W/D) in lung tissue,lung coefficient and lung water content in ES group also significantly lower than those in Sepsis group at given intervals (P<0.05).④ Western Blot revealed at 6 h,12 h and 24 h after modeling,the protein levels of TLR4 and NF-κ B in lung tissue in Sepsis group and ES group were significantly increased compared with SH group (P<0.05),and the protein levels of TLR4 and NF-κ B in lung tissue of ES group were also significantly lower than those in Sepsis group at all given intervals (P<0.05).⑤ The lightest degree of pathological change was observed in SH group,the most serious degree of pathological change was found in Sepsis group,and the pathological change was significantly alleviated in ES group compared with Sepsis group whereas the pathological change was significantly increased compared with SH group at all given intervals.Conclusions Esmolol can promote the secretion of catecholamine,inhibit the release of inflammatory cytokines,reduce lung permeability,reduce pulmonary edema,and thus play an important role in protecting the lungs.The mechanism may be that esmolol improves the responsiveness of β-adrenergic receptor to catecholamine,and regulates the level of inflammatory cytokines by inhibiting TLR4-NF-κB-TNF-α signaling pathways,thus exerting protective effect on the lungs.

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.

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
Objective To find out about the charateristics of bone mineral density(BMD)and its influencing factors among 2079 recruits.Methods Recruits of Armed Police Force in Tianjin were selected as subjects.Their BMD was measured with dual-energy X-ray absorptiometry(DXA).A normal group and low bone mineral density group were selected according to the results of bone mineral density and the methord of 1:1 case-control analysis.Questionnaires were used to investigate their dietary nutrition and lifestyles.One-way ANOVA,chi-square test and Logistic regression analysis were used to explore the influencing factors of BMD.Results In total,2079 military recruits underwent a DXA scan.Normal bone mineral density accounted for 44.78%,and T value was -0.36 ±0.62.Medium bone mineral density made up 50.51%, and T value was -1.57 ±0.38.Low bone mineral density accounted for 4.71%,and T value was -2.82 ±0.39.Single factor analysis suggested that body weight, BMI, movement time, sports venues, spending too much time online all had influences on bone mineral density.Multiariable Logistic regression analysis showed that high animal diet(OR=3.435), spending too much time online(OR=1.246)were the risk factors for bone density.Dairy consumption(OR=0.296)and movement time(OR=0.549)were positively associated with bone mineral density.Conclusion There is a low bone mass in the recruits.We suggest that scientific and standardized management,popularization of knowledge,healthy diet and living habits are necessary to promote good bone peaks.

ABSTRACT
<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>

<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>

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 explore the role of Dlx1as, a natural antisense transcript, in mice brain development.</p><p><b>METHODS</b>Based on the bioinformatic and molecular biological findings, we confirmed whether the Dlx1as has a poly-A tail. The temporal expressions of Dlx1as and Dlx1 mRNA were determined by quantitative real-time PCR and the spatial expressions of Dlx1as and Dlx1 mRNA were compared by using in situ hybridization.</p><p><b>RESULTS</b>Dlx1as had a poly-A signal. Dlx1as's expression was at a high level through a period of time in the embryo development, which was similar with Dlx1 mRNA in temporal but different in spatial.</p><p><b>CONCLUSIONS</b>Dlx1as is highly expressed in a certain period during mice brain development, which spatially supplements the mRNA expression of D1x1. Therefore, it is supposed that Dlx1as influences the mice brain development by regulating Dlx1 mRNA.</p>

<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>
