RESUMO

To analyze the use of outcome indicators of randomized controlled trial(RCT) of acupuncture in the treatment of acute ischemic stroke in recent three years, so as to provide a basis for building a study on the core outcome indicators for the treatment of acute ischemic stroke with acupuncture. The RCTs of acupuncture treatment for acute ischemic stroke in recent three years were collec-ted through computer retrieval of eight Chinese and English databases and two clinical trial registries at home and abroad. Literature was screened out, and data was extracted. Risk of assessment bias tool Cochrane 6.1 was used for bias risk assessment, outcome indicators were summarized and analyzed. A total of 47 RCTs were included, and 3 studies were trials registration scheme. Outcome indicators were divided into 6 categories according to functional attributes, namely physical symptoms/signs, physical and chemical examination, quality of life, traditional Chinese medicine symptoms/syndromes, safety events and long-term prognosis. The study found that in addition to the common problems in previous studies covered by the status quo of outcome indicators selection of RCT of acupuncture in the treatment of acute ischemic stroke, there were also the other problems as follows: emphasis on macroscopic efficacy indicators but neglect of acupuncture specific indicators, lack of characteristic indicators and economic indicators of traditional Chinese medicine therapy, and unification of indicators measurement tool and measurement time point. In the future, the outcome indicators set for the treatment of acute ischemic stroke with acupuncture shall be established, and the core outcome indicators set shall be in line with the characteristics of traditional Chinese medicine treatment.

RESUMO

There have been many clinical trials, systematic reviews/Meta-analysis proving that Xingnaojing Injection has a good clinical efficacy in treatment of cerebral ischaemic stroke, but with fewer comprehensive descriptions. In this study, an overview of systematic reviews/Meta-analysis of Xingnaojing Injection in treating cerebral ischaemic stroke was performed to provide current situation of evidences and basis for clinical practice. CNKI, Wanfang, VIP, CBM, EMbase, PubMed, Cochrane Library, Web of Science were retrieved through computers. A total of 6 literatures were included in this study. By AMSTAR-2 checklist and GRADE, the quality of included systematic reviews and the efficacy of Xingnaojing Injection were evaluated. The results of AMSTAR-2 checklist showed an extremely low quality for all of the 6 systematic reviews. According to the results of GRADE evaluation, among 55 outcomes, there were 2 outcomes with a medium quality, 4 outcomes with a low quality and 49 outcomes with an extremely low quality. The 6 systematic reviews reached a consistent conclusion that Xingnaojing Injection was effective in the treatment of cerebral ischaemic stroke. This therapy could improve the total efficacy, neurological deficit scores, hemodynamic and hemodynamic parameters. However, the methodolo-gical quality of all literatures was extremely low. The evidence levels of outcomes were between extremely low to medium. The effectiveness of Xingnaojing Injection in the treatment of cerebral ischaemic stroke still needs to be further verified by more high-quality studies. In the future, relevant clinical studies and systematic reviews/Meta-analysis shall be carried out in a strict accordance with relevant regulations.

RESUMO

To overview the systematic reviews of Panax notoginseng saponins in the treatment of acute cerebral infarction. CNKI, CBM, Wanfang, VIP, PubMed, Cochrane Library and EMbase databases were retrieved to collect the systematic reviews of the efficacy of P. notoginseng saponins in the treatment of acute cerebral infarction. The retrieval time was from the time of database establishment to January 2021. After two researchers independently screened out the literature and extracted the data, AMSTAR-2 scale was used to evaluate the methodological quality of the included systematic reviews, GRADE system was used to grade the quality of evidences of the outcome indicators, and the efficacy evaluation was summarized. A total of 5 systematic reviews were included. AMSTAR-2 evaluation results showed that 3 items were relatively complete, while 4 items had a poor overall quality. P. notoginseng saponins combined with conventional Western medicine therapy was superior to single conventional therapy in the recovery of neurological function, enhancement of the total effective rate in clinic, and improvement of activities of daily living. GRADE evaluation results showed that the quality of evidence was from low quality to very low quality. In conclusion, in the treatment of acute cerebral infarction, P. notoginseng saponins can improve the clinical efficacy, with a good safety but a not high methodological quality and a low evidence quality. It is suggested that high-quality clinical studies shall be further carried out to provide evidence-based basis for the application of P. notoginseng saponins in the treatment of acute cerebral infarction.

RESUMO

Fangcang shelter hospitals were established in China during the coronavirus disease 2019 (COVID-19) pandemic as a countermeasure to stop the spread of the disease. To our knowledge, no research has been conducted on mental health problems among patients in Fangcang shelter hospitals. This study aimed to determine the prevalence and major influencing factors of anxiety and depressive symptoms among COVID-19 patients admitted to Fangcang shelter hospitals. From February 23, 2020, to February 26, 2020, we obtained sociodemographic and clinical characteristics information of COVID-19 patients in Jianghan Fangcang Shelter Hospital (Wuhan, China) and assessed their mental health status and sleep quality. Data were obtained with an online questionnaire. The questionnaire consisted of a set of items on demographic characteristics, a set of items on clinical characteristics, the Self-Rating Anxiety Scale, Self-Rating Depression Scale, and Pittsburgh Sleep Quality Index. Three hundred seven COVID-19 patients who were admitted to Jianghan Fangcang Shelter Hospital participated in this study. The prevalence of anxiety and depressive symptoms were 18.6% and 13.4%, respectively. Poor sleep quality and having ≥ two current physical symptoms were independent risk factors for anxiety symptoms. Female sex, having a family member with confirmed COVID-19, and having ≥ two current physical symptoms were independent risk factors for depressive symptoms. Anxiety and depressive symptoms were found to be common among COVID-19 patients in Fangcang Shelter Hospital, with some patients being at high risk.

RESUMO

BACKGROUND/AIMS: Thymic stromal lymphopoietin (TSLP) is a cytokine that plays diverse roles in the regulation of immune responses. However, a detailed understanding of the TSLP signaling pathway in asthma remains elusive. In this study, we aimed to investigate the role of the TSLP signaling pathway in asthma and its effect on airway inflammation and remodeling. METHODS: Forty Sprague Dawley (SD) rats were evenly classified into control, asthma, IgG2a mAb and anti-TSLP mAb groups. Ovalbumin (OVA)-induced asthma models were successfully established. Blood, bronchoalveolar lavage fluid (BALF) and lung tissue samples were prepared. Total BALF leukocytes were counted, and the proportions of different leukocyte types were determined. Reverse transcription quantitative polymerase chain reaction (RT-qPCR) and immunohistochemistry were performed to determine the mRNA and protein levels of TSLP, OX40L, α-smooth muscle actin (α-SMA, a marker of airway remodeling in asthma) and collagen I in the plasma. Enzyme-linked immunosorbent assay (ELISA) was carried out to measure the concentrations of TSLP, OX40L, and other inflammatory factors, such as interferon (IFN)-γ, interleukin (IL)-4, IL-5 and IL-13, in the plasma. RESULTS: Compared with the control group, there were more leukocytes, increased EOS and LYM proportions, higher Underwood and PAS scores, increased WTt, WTm, WAt/A0, WAm/WAt, WTt/R0, WTm/WTt, TSLP, OX40L, a-SMA and collagen I mRNA and protein levels, and higher SLP, OX40L, IL-4, IL-5 and IL-13 levels, but lower MON proportions and IFN-γ levels in the asthma and IgG2a mAb groups. Compared with the asthma and IgG2a mAb groups, there were less leukocytes, decreased EOS and LYM proportions, lower Underwood and PAS scores, decreased WTt, WTm, WAt/A0, WAm/WAt, WTt/R0, WTm/WTt, TSLP, OX40L, a-SMA and Collagen I mRNA and protein levels, and lower levels of SLP, OX40L, IL-4, IL-5 and IL-13, but higher MON proportions and IFN-γ levels in the anti-TSLP mAb group. WTm and WTt were positively associated with the TSLP, OX40L, α-SMA and collagen-I levels in the rat lung tissues. CONCLUSION: The results indicate that TSLP may be an important contributor for asthma development as TSLP signaling blockade attenuates airway inflammation and remodeling in asthmatic rats.

RESUMO

In the present study, the effects of tubeimoside I (TBMS1) on particulate matter <2.5 µm in diameter (PM2.5)-induced pulmonary injury and its mechanisms of action were investigated. Male BALB/c mice were randomly assigned into five groups (n=10/group): Control, PM2.5, PM2.5 + TBMS1 45 mg/kg, PM2.5 + TBMS1 90 mg/kg and PM2.5 + TBMS1 180 mg/kg. The dose of the PM2.5 suspension administered to the mice was 40 mg/kg via nasal instillation. The PM2.5 + TBMS1 groups received TBMS1 daily orally for 21 consecutive days, while the mice in the control and PM2.5 groups received equivalent volumes of PBS. Subsequently, lactic dehydrogenase, acid phosphatase, alkaline phosphatase, albumin, tumor necrosis factor-α and interleukin-6 protein levels in bronchoalveolar lavage fluid were determined. Oxidative stress was evaluated by detecting the protein levels of malondialdehyde, superoxide dismutase and inducible nitric oxide synthase, and the level of nitric oxide in lung tissue. Lastly, histopathological images of lung sections were obtained to observe changes in the lung tissue with treatment. The results indicated that exposure to PM2.5 induced pathological pulmonary changes, and biofilm and parenchymal cell damage, and promoted inflammation and oxidative stress. Treatment with TBMS1 attenuated the development of PM2.5-induced pulmonary injury. Its mechanisms of action were associated with reducing cytotoxic effects, levels of inflammatory mediators and oxidative damage. In conclusion, the results of the present study indicate that TBMS1 is a potential therapeutic drug for treating PM2.5-induced pulmonary injury.

RESUMO

This study aims to explore how microRNA-145 (miR-145) affects airway remodeling and cytokine expression by targeting epidermal growth factor receptor (EGFR) to regulate mucin 5AC (MUC5AC).Mice alveolar epithelial cells (AECs) were divided into a control, blank, miR-145 mimics, mimic control, miR-145 inhibitors, inhibitor control, si-EGFR and miR-145 inhibitors + si-EGFR group. Asthma mice models with airway remodeling were induced with an Ovalbumin (OVA) solution and randomly divided into a normal, asthma, asthma + miR-145 mimics, asthma + miR-145 mimic control, asthma + si-EGFR or asthma + si-EGFR NC group. Airway remodeling degree and histomorphology was measured using hematoxylin-eosin (HE), Masson and periodic acid-Schiff (PAS) staining. Flow cytometry was used to detect Th2 and Th17 cells in peripheral blood, ELISA was used to measure inflammatory factors. qRT-PCR and western blotting was adapted to detect the expressions of EGFR and the relevant cytokines that are regulated by miR-145.The control, miR-145 mimics and si-EGFR groups showed a higher expression of miR-145 and a lower expression of EGFR and cytokines than the blank, mimic control, inhibitor control and miR-145 inhibitor + si-EGFR groups. Mice in the asthma + miR-145 mimics and asthma + si-EGFR groups showed lower WAt/Pbm, WAi/Pbm and WAm/Pbm, less inflammatory cells, less airway modeling and alleviated goblet cell hyperplasia and mucus obstruction than the asthma group. Furthermore, the expressions of EGFR and cytokines of transfected cells and lung tissues were negatively related to those of miR-145. MiR-145 can down-regulate MUC5AC by negatively targeting EGFR and thereby relieving airway remodeling.

RESUMO

Biochemical methane potential experiments were conducted to investigate the effects of organic loading rate on the performance of anaerobic digesters with vinegar residues. According to the comparisons of methane production and liquid phase compositions, as well as thermogravimetry, X-ray Diffraction and infrared spectroscopy analyses, the conclusions could be drawn that:①Lower organic loading rate was better to mitigate the accumulation of VFAs and pH decrease during the hydrolysis and acidification of organic matters, which consequently improved methane production. When the inoculum to substrate ratio was 1:1[organic loading rate of 1.78 g·(L·d)-1, pH=7.60], the cumulative methane production was the highest, reaching 2249.7 mL, and the performance of the digesters was stable. The VFAs content increased with the increase of the organic loading rate, leading to the suppression and further the stop of methane production. And when the inoculum to substrate ratio was 1:4[organic loading rate of 7.12 g·(L·d)-1, pH=5.52], the simultaneous generation of acetate and lactic acids could be achieved at 8000 mg·L-1 and 2650 mg·L-1, respectively. ② As vinegar residues were short-range ordered with microcrystalline structure or mainly contained amorphous substances, they were more biodegradable than feedstocks such as corn stalk. During the anaerobic digestion processes, the degradation rates of lignin, cellulose and hemicellulose increased with the decrease of organic loading rate.

RESUMO

High free ammonia nitrogen (FAN) is regarded as a main factor that inhibits biogas production in high solid anaerobic digestion systems with dewatered sludge. Two mesophilic semi-continuous anaerobic digesters fed with dewatered sludge (input total solids=15%) were operated and their performance under different FAN concentrations by two regulation methods including pH reduction and total ammonia nitrogen (TAN) promotion were investigated. Results showed that when FAN was elevated from (400±174) mg·L-1 to (526±25) mg·L-1 with the increase of TAN, the daily biogas yield declined from (11.9±0.3) L·d-1 to (10.3±0.2) L·d-1. Meanwhile, volatile solids (VS) reduction rate decreased by 33.7%. When FAN dropped from (330±99) mg·L-1 to (47±13) mg·L-1 due to pH reduction, daily biogas yield declined from (14.4±1.1) L·d-1 to (10.8±0.3) L·d-1 and VS reduction rate decreased by 26.9%. The system performance was not enhanced with the reduction of FAN. With the stop of pH regulation, FAN gradually raised again to 300 mg·L-1 and digester performance recovered to the same as the situation before regulation. The result suggested that inhibition occurred during pH reduction. By 16S rRNA pyrosequencing analysis on bacterial and archaeal diversity and quantitative PCR analysis aiming at methanogens, it was found that bacterial community structure both changed obviously with obvious performance decline in the two digesters. Excessive FAN (>500 mg·L-1) could change the main bacteria species which degrade protein from Tepidimicrobium and Proteiniborus to Anaerobranca. On the other hand, some carbohydrate and protein degrading bacteria were also inhibited by pH reduction for FAN control, leading to the decline of hydrolysis rates of organic matters. As a result, the shortage of substrate supply for the methanogens weakened the biogas production of the digestion system.

RESUMO

Fluoroquinolone antibiotics (FQs), as the common pharmaceuticals and personal care products (PPCPs), are widespread in the environment. FQs contained in wastewater would be ultimately enriched in sludge, posing a potential threat to the consequent sludge utilization. To optimize the analytical method applicable to the determination of FQs in sludge, the authors selected ofloxacin (OFL), norfioxacin (NOR), ciprofloxacin (CIP) and lomefloxacin (LOM) as the target FQs, and established a method which was based on cell lysis, FQs extraction with triethylamine/methanol/water solution, Solid Phase Extraction (SPE) and HPLC-Fluorescence Detection (FLD) determination. After the investigation, phosphoric acid-triethylamine was decided to be the buffer salt, and methanol was chosen as the organic mobile phase. The gradient fluorescence scanning strategy was proved to be necessary for the optimal detection as well. Furthermore, by the designed orthogonal experiments, the effects of the extraction materials, pH, and the eluents on the efficiency of SPE extraction were evaluated, by which the optimal extraction conditions were determined. As a result, FQs in liquid samples could be analyzed by utilizing HLB extraction cartridge, and the recovery rates of the four FQs were in the range of 82%-103%. As for solid samples, the recovery rates of the four FQs contained reached up to 71%-101%. Finally, the adsorptivity of the sludge from the different tanks ( anaerobic, anoxic and oxic tanks) was investigated, showing gradual decrease in the adsorption capacity, but all adsorbed over 90% of the EQs. This conclusion also confirmed that 50% removal of FQs in the domestic wastewater treatment plant was realized by sludge adsorption.

RESUMO

OBJECTIVE: To observe the auxiliary efficacy and safety of Hebi Recipe (HR)in treating early rheumatoid arthritis (RA). METHODS: Totally 63 early RA patients with Gan-Pi disharmony were randomly assigned to the treatment group [32 cases, treated by HR (one dose per day, taken in two portions for 24 successive weeks) plus Methotrexate (MTX)] and the control group (31 cases, treated by MTX alone). The dosage of MTX was increased from 7.5 mg to 12.5 mg, once per week, 24 weeks as one course of treatment. Efficacy for Chinese medical syndromes, American College of Rheumatology 20 (ACR20) improvement rate, disease activity score in 28 joints (DAS28), laboratory related indices [ESR, rheumatoid factor (RF), C-reactive protein (CRP), anti-cyclic citrullinated peptide (CCP)], and related ultrasonic inspection items (synovium thickness, synovium blood flow classification, effusion of joint), and adverse reactions were observed. RESULTS: The total effective rate (83.9%, 26/31 cases) and ACR20 improvement rate (74.2%, 23/31 cases) were higher in the treatment group than in the control group [60.7% (17/28 cases), 46.4% (13/28 cases); P < 0.05]. Compared with before treatment in the same group, DAS28 score, ESR, RF, CRP, CCP, synovium thickness, synovium blood flow classification, effusion of joint all decreased in the two groups after treatment (P < 0.01, P < 0.05). Compared with the control group after treatment, ACR20 improvement rate, DAS28 score, ESR, RF, CRP, CCP, synovium thickness, synovium blood flow classification, effusion of joint all decreased in the treatment group (P < 0.01, P < 0.05). Liver dysfunction occurred in 1 case of the treatment group. One leucopenia and 2 liver dysfunction occurred in the control group. CONCLUSION: HR could effectively improve joints and systemic symptoms of early RA patients with Gan-Pi disharmony.

RESUMO

Rice seed storage proteins glutelin and α-globulin are synthesized in the endoplasmic reticulum (ER) and deposited in protein storage vacuoles (PSVs). Sar1, a small GTPase, acts as a molecular switch to regulate the assembly of coat protein complex II, which exports secretory protein from the ER to the Golgi apparatus. To reveal the route by which glutelin and α-globulin exit the ER, four putative Sar1 genes (OsSar1a/b/c/d) were cloned from rice, and transgenic rice were generated with Sar1 overexpressed or suppressed by RNA interference (RNAi) specifically in the endosperm under the control of the rice glutelin promoter. Overexpression or suppression of any OsSar1 did not alter the phenotype. However, simultaneous knockdown of OsSar1a/b/c resulted in floury and shrunken seeds, with an increased level of glutelin precursor and decreased level of the mature α- and ß-subunit. OsSar1abc RNAi endosperm generated numerous, spherical, novel protein bodies with highly electron-dense matrixes containing both glutelin and α-globulin. Notably, the novel protein bodies were surrounded by ribosomes, showing that they were derived from the ER. Some of the ER-derived dense protein bodies were attached to a blebbing structure containing prolamin. These results indicated that OsSar1a/b/c play a crucial role in storage proteins exiting from the ER, with functional redundancy in rice endosperm, and glutelin and α-globulin transported together from the ER to the Golgi apparatus by a pathway mediated by coat protein complex II.

RESUMO

1. Ginkgo biloba extract (GBE) is one of the most commonly used herbal remedies worldwide. It is usually concomitantly administrated with statins to treat diseases in geriatric patients. We aim to determine the influence of GBE on the pharmacokinetics (PK) and pharmacodynamics of simvastatin, which is currently unknown. 2. An open-label, randomized, two-period, two-treatment, balanced, crossover study was performed in 14 healthy volunteers. Subjects received simvastatin 40 mg once daily, co-treated with placebo or GBE 120 mg twice daily. Each treatment was administered for 14 d, separated by a wash-out period of 1 month. Simvastatin, simvastatin acid and lipoprotein concentrations were assessed. 3. GBE administration reduced mean simvastatin area under the curve (AUC)0-24, AUC0-∞ and Cmax by 39% (p = 0.000), 36%(p = 0.001) and 32% (p = 0.002), respectively, but did not cause significant differences in simvastatin acid PK or its cholesterol-lowering efficacy. 4. GBE consumption decreased simvastatin system exposure, but did not affect simvastatin acid PK. However, we cannot rule out the possibility for a pharmacodynamic interaction between GBE and simvastatin in vivo.

RESUMO

At solid retention time (SRT) of 20 days, biogas production, volatile solid (VS) degradation and system stability in co-digestion systems of dewatered sludge (DS) and kitchen garbage (KG) were investigated in semi-continuous completely mixed reactors numbered R1-R5 (the DS/KG of their feeding substrate based on wet mass was 1:0, 4:1, 3:2, 2:3 and 0:1, respectively). The results showed that, with larger proportion of KG in feeding substrate, higher methane yield and biogas yield were obtained with lower methane content. For certain reactor at given SRT, KG addition could significantly improve the organic loading rate (OLR) and volume biogas production. System with more KG addition favored higher hydraulic constant k and VS reduction. The hydraulic constant k was 0.25 d(-1), 0.61 d(-1), 1.09 d(-1) and 1.56 d(-1), and the VS reduction was 37.4%, 50.6%, 60.7% and 68.2% for R1-R4, respectively, indicating higher hydrolysis rates with more KG addition, which led to increased VS reductions. With larger KG proportion in feeding substrate, pH, total alkalinity (TA), total ammonia nitrogen (TAN) and free ammonia nitrogen (FAN) showed decreasing trend. As KG addition increased by 60%, pH, TA, TAN and FAN decreased by 6%, 16%, 22% and 75%, respectively. FAN and Na+ respectively were potential inhibitory chemicals that threatened the stability of the mono-system of DS and KG. In comparison with the mono-system of DS or KG, the co-system showed higher stability by diluting toxic chemicals like ammonia or Na+ to much lower levels.

RESUMO

OBJECTIVE: To detect the anxiety and depression status of BALB/c asthmatic model in mice. METHODS: A total of 20 mice were randomly divided into asthma and control groups (n = 10 each). The animals were sensitized and challenged with ovalbumin for asthmatic model. Phosphate buffer solution was used in the control group. The mice were challenged with increasing concentrations of methacholine aerosol and the airway resistance was measuring non-invasively by enhanced pause (Penh). And elevated plus maze test system and forced swim were employed to evaluate their anxiety and depression status. Then bronchoalveolar lavage cytology was detected for evaluating the airway inflammation. RESULTS: In both groups, Penh value increased with the rising concentration of methacholine. The Penh values of asthmatic mice exciting with normal saline and methacholine concentration of 0, 5 g/L were 0.43 ± 0.04, 0.41 ± 0.05 and 0.44 ± 0.04 versus 0.42 ± 0.03, 0.39 ± 0.03,0.43 ± 0.04 in control group. The difference had no statistical significance (P = 0.290,0.652,0.723). At the concentration of methacholine 10, 15, 20 g/L, the Penh values of asthmatic mice were 0.57 ± 0.03,0.85 ± 0.04, 1.57 ± 0.08 and they were significantly higher than those of control group (0.45 ± 0.08,0.57 ± 0.06,0.82 ± 0.09) (P = 0.001,0.000,0.000). Asthmatic mice in the elevated plus maze on a behavioral test and found that asthmatic mice open arm entries sum closed arm entries (OE+CE), percent of open arm/total entries (OE%) and percent of open arm/total time (OT%) was (18.3 ± 3.6) times, (22.2 ± 3.1)%, (16.7 ± 4.2)%. They were significantly lower than those of control group ((24.0 ± 2.9) times,(28.0 ± 3.4)%, (21.8 ± 4.6)%) (P = 0.001,0.001,0.019). Asthmatic mice swimming time was significantly higher than that of control group (147 ± 12) vs (133 ± 10) s (P = 0.010). The total number of cells and eosinophil ratio in asthma group was (10.0 ± 4.0)×10(5)/ml and (68.18 ± 3.76)%. And they were significantly larger than those of control group ((1.7 ± 0.4)× 10(5)/ml, (0.12 ± 0.07)%) (both P = 0.000). CONCLUSION: Asthmatic mice with concurrent anxiety and depression may be a model for elucidating the molecular mechanisms of asthma with anxiety and depression.

RESUMO

OBJECTIVE: To explore the relationship between psychological status of depression and anxiety and asthma control. METHODS: A total of 144 definite physician-diagnosed asthmatics at First Affiliated Hospital, Zhengzhou University from March 2011 to March 2012 were evaluated with the self-rating anxiety scale (SAS) and self-rating depressive scale (SDS). And 85 healthy subjects were selected as the controls and evaluated by the asthma control test (ACT). The incidence of anxiety and depression and scores of SAS and SDS was compared between the asthma group and health controls. The relationship was analyzed between the scores of ACT and SAS or SDS respectively. The subjects were divided into anxiety, non-anxiety, depression and non-depression groups according to the scores of SAS and SDS. The inter-group differences in ACT scores were compared. According to the asthma control test scale, the asthmatics were divided into the control, non-control and partial control groups. And the inter-group differences in the scores of SAS and SDS were compared. RESULTS: Anxiety (20.1%) and depression (35.4%) was more common in asthmatics than healthy controls (both P < 0.01). Scores of SAS (40.8 ± 8.1) and SDS (44.9 ± 9.1) in physician-diagnosed asthmatics were higher than the controls and general community (both P < 0.01). Scores of ACT in non-anxiety group (18.6 ± 4.4) were higher than those in anxiety group, higher in non-depression group (18.5 ± 4.6) than depression group (both P < 0.01). Scores of SAS (control group: 33.6 ± 4.3, non-control group: 43.7 ± 7.8 and partial control group: 37.6 ± 7.1) and SDS (control group: 35.1 ± 6.7, non-control group: 47.2 ± 9.7 and partial control group: 43.3 ± 6.6) in physician-diagnosed asthmatics varied among different control levels (both P < 0.01). The anxiety, depression scores and ACT scores were negatively correlated in asthmatics (r = 0.52 and 0.23, both P < 0.01). With the rising scores of SAS and SDS, ACT score decreases (b = -0.29 and -0.12, both P < 0.01). CONCLUSIONS: Anxiety and depression moods are more common in asthmatics than healthy controls. The worse asthma control, the more severity of anxiety and depression, and vice versa.

RESUMO

The current study was performed to assess any association between the methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism and risk of lung cancer in Henan province. This case-control study involved94 patients with newly histological confirmed lung cancer and 78 healthy controls. Genotyping was achieved with peripheral blood lymphocytes DNA and association of the polymorphism with risk of lung cancer was estimated by unconditional logistic regression analysis. The frequencies of the MTHFR 667TT genotype were 37.2% in cases compared with 23.1% in controls (χ2 = 4.008, P = 0.045). Individuals with the 667CC/CT genotype displayed a significantly reduced risk of lung cancer compared with those with the TT genotypes [adjusted odds ratio (OR), 0.506; 95% confidence interval (95% CI), 0.258 - 0.991]. The C667T polymorphism might have a significant effect on the occurrence of lung cancer in Henan province.

RESUMO

3' untranslated regions (UTRs) are important sequence elements that modulate the expression of genes. We evaluated the potential of the 3'-UTRs of 9 seed storage protein (SSP) genes as terminators in enhancing the expression of the ß-glucuronidase (gus A) reporter gene driven by the glutelin GluB-3 promoter in stable transgenic rice lines. Six of the 3'-UTRs significantly enhanced the activity of the GluB-3 promoter without changing its tissue specificity but altered its expression pattern in endosperm. With the 3'-UTRs of GluB-5, GluA-2 and GluC, the expression of gus A was higher by 3.12-, 2.45- and 2.14-fold, respectively, than with the Nos terminator. These three 3'-UTRs, combined with GluC, Ubi-1 and CaMV35S promoters, also increased GUS levels in stable transgenic rice lines or in transient expression in protoplasts, which indicated that the enhancements were independent of the promoter sequence. The increase in protein production was accompanied by altered mRNA levels, which suggests that the enhancements were due to increased transcript level. The 3'-UTRs of GluB-5, GluA-2 and GluC, when combined with strong promoters, might be ideal candidates for high production of recombinant proteins in rice seeds. The 9 SSP 3'-UTRs could function as faithful terminators in mono- or multi-gene transformation avoiding homology-based gene silencing.
