Abstract
Food poisoning caused by Nassariidaes has occurred frequently in coastal areas of China, especially in summer and autumn. Nassariidaes poisoning can be manifested as lip and tongue paralysis, dizziness, headache, nausea and vomiting, arrhythmia and even respiratory failure. We admitted a case of respiratory failure caused by eating Nassariidaes. After timely respiratory support, hemoperfusion and other active treatment, the patient was recovered and was discharged. This paper summarized clinical characteristics and treatment of Nassariidaes poisoning, in order to provide reference for clinical diagnosis and treatment of similar cases.

Abstract
Objective: To investigate the predictive value of serum lactate dehydrogenase (LDH) in the prognosis of patients with paraquat (PQ) poisoning, and to provide evidence for early prognosis assessment. Methods: In February 2022, 50 patients with PQ poisoning who completed serum LDH detection admitted to the Department of Emergency Medicine, the First Affiliated Hospital of Wenzhou Medical University from January 2012 to December 2021 were selected as the observation group, and 50 healthy physical examination personnel were randomly selected as the control group. Patients with PQ poisoning were divided into survival group and death group according to the prognosis, and the differences of blood routine routine, liver and kidney function and other indicators in the first admission between the two groups were compared. Multivariate logisitic regression model was established, ROC curve was drawn, and the influencing factors of prognosis of patients with PQ poisoning were analyzed. Results: Compared with the control group, the white blood cell count (WBC), total bilirubin (TBil), alanine aminotransferase (ALT), aspartate aminotransferase (AST), LDH, glucose (GLU) and creatinine (Cr) in observation group were significantly increased, while albumin (ALB) and total cholesterol (TC) were significantly decreased (P<0.05). Univariate analysis showed that WBC, elevated LDH (>247 U/L), TBil, ALT, AST and Cr were significantly different between PQ poisoning survival group and death group (P<0.05). Multivariate logisitic regression analysis showed that elevated serum LDH was an independent risk factor for the prognosis of PQ poisoning patients (OR=9.95, 95%CI: 1.34-73.82, P=0.025). The area under the ROC curve of LDH was 0.811 (95%CI: 0.692-0.930). When the cut-off value was 340 U/L, the sensitivity was 0.889 and the specificity was 0.719. Log-rank test showed that there was a statistically significant difference in survival rate between the normal LDH group and the elevated LDH group (P=0.001) . Conclusion: Serum LDH has a good predictive value in evaluating the prognosis of patients with PQ poisoning. Elevated LDH is a risk factor for poor prognosis of patients with PQ poisoning.

Abstract
Bardet-Biedl syndrome (BBS) is a rare autosomal recessive ciliopathy, which is caused by mutations mainly in genes encoding BBSome complex and IFT complex. Here, we reported a 21-year-old female with BBS characterized by three primary features including obesity, retinitis pigmentosa sine pigmento and bilateral renal cysts. She also had some secondary features such as diabetes mellitus, nonalcoholic fatty liver disease, subclinical hypothyroidism and mild conductive hearing damage. Whole exome sequencing revealed two compound heterozygous mutations in exon 2 of the BBS12 gene (c.188delC, p.T63fs and c.1993_1995del, p.665_665del) in this patient. Sanger sequencing showed that her father and mother carried c.188delC (p.T63fs) and c.1993_1995del (p.665_665del) variants, respectively, while her parents were free of BBS-related symptoms. In conclusion, this case reported two novel mutations (c.188delC, p.T63fs and c.1993_1995del, p.665_665del) of the BBS12 gene in a girl presented with BBS, which provides novel genetic resources for studies of the disease. Meanwhile, the BBS case shows the entire development progress from her birth to adulthood, which helps facilitate clinicians' understanding of BBS.

Abstract
Objective: To investigate the protective effect and mechanism of Nicotinamide Riboside (NR) on lung injury caused by Paraquat intoxicated mice. Methods: Eighty clean male BALB/C mice were selected and averagely divided forty mice into 4 groups with 10 mice in each group, PQ group was given 25% PQ solution (60 mg/kg) by one-time gavage. PQ+NR group were intraperitoneally injected with NR solution (300 mg/kg) 1 hour before given the same amount of PQ solution (60 mg/kg) by one-time gavage, The Control group were given the same amount of saline by one-time gavage, The same amount of NR was intraperitoneally injected before NR group were given saline by one-time gavage. Observed and recorded general condition of PQ intoxicated mice. Observed and recorded the death of mice every half an hour and counted the mortality and drew survival curve of each group after 72 hours exposure. another forty mice were averagely divided and treated by the same way. After 24 hours of modelling, mice were anaesthetized and killed. Then blood was extracted after eyeball was removed. The changes of TNF-a、IL-6 and MPO in serum of mice were detected by ELISA.Two lung tissues were removed from the chest and used to measure the D/W ratio of the lung. The pathological changes of lung were observed and scored under light microscope.The levels of SOD, MDA and Caspase-3 in lung tissues were determined by chemical colorimetry. The expression of Sirt1 and Nrf2 in lung tissues was detected by Western-blot. Results: Compared with the Control group and the NR group, the mice in the PQ group had a poor general condition, such as depression, crouching, skin disorder and reduced activity, food, urine and feces. The symptoms in the PQ+NR group were reduced compared with the PQ group. The survival rate at 72 hours after exposure: 80% in the PQ+NR group and 40% higher than that in the PQ group (P=0.029) . Compared with Control group and NR group, the D/W ratio (0.09±0.07) , lung pathology score under light microscope (11.80±0.37) , TNF-a (39.89±1.48) pg/ml、IL-6 (77.29±2.38) pg/ml、MPO (0.31±0.01) μg/ml、SOD (6.62±0.30) U/mgprot、MDA level (1.21±0.14) mmol/mgprot, Caspase-3 activity (356.00± 27.16) %, Sirt1 and Nrf2 protein expression (1.02±0.14、0.82±0.06) were significantly decreased in PQ group (P=0.004、0.023) ; Compared with PQ group, PQ+NR group significantly increased the D/W ratio (0.10±0.10) , decreased the pulmonary pathology score under light microscope (7.400.51) , decreased TNF-a (33.00± 0.65) pg/ml、IL-6 (52.23±4.23) pg/ml、MPO leve (0.23±0.01) μg/mll, increased SOD leve (9.28±0.45) U/mgprotl, decreased MDA level (0.78±0.02) mmol/mgprot, decreased Caspase-3 activity (222.80±7.59) %, and increased the protein expressions of Sirt1 and Nrf2 (1.62±0.16、1.06±0.04) (P=0.048、0.035) . Conclusion: NR can prolong the survival time of PQ poisoned mice; NR intervention can effectively inhibit the inflammatory response, peroxidation injury and apoptosis of PQ poisoned mice; NR intervention can upregulate the expression of Sirt1 and Nrf2 protein and effectively reduce the lung injury of PQ poisoning.

Abstract
Aeromonas hydrophila was a common bacterial pathogen in aquaculture resulting in considerable losses to the striped catfish aquaculture industry. As an emergent antimicrobial peptide (AMP), NK-lysin (NKL) had activity against various microorganisms. However, the antibacterial activity of NKL from striped catfish (Pangasianodon hypophthalmus) both in vitro and vivo remains unclear. In this study, the cDNA sequence of P. hypophthalmus NK-lysin gene (PhNK-lysin) was cloned and characterized. The amino acid sequence of PhNK-lysin contains a signal peptide sequence of 17 amino acid (aa) residues and a mature peptide composed of 130 aa. The saposin B domain of mature peptide comprised six conserved cysteines forming three putative disulfide bonds. Phylogenetic analysis revealed that the PhNK-lysin was most closely related to that of the channel catfish (Ictalurus punctatus) NK-lysin. The transcriptional levels of the PhNK-lysin were significantly upregulated in response to A. hydrophila infection in various tissues including heart, liver, spleen, head kidney, trunk kidney and gill. The synthetic PhNK-lysin-derived peptide consisting of 38aa showed antibacterial activity against Vibrio harveii, Aeromonas hydrophila and Escherichia coli. The MIC for V. harveii, A. hydrophila and E. coli were 15.625 μM, 250 μM and 31.25 μM respectively. Besides, the synthetic PhNK-lysin decreased the bacterial load of liver and trunk kidney in vivo as well as increased the survival rate of A. hydrophila infected striped catfish. Hence, these data suggest that PhNK-lysin had antimicrobial effect and protects the host from pathogenic infection.

Abstract
Objective: To investigate the predictive value of the product of first plasmacolchicine concentration and poisoning time for the prognosis of colchicine poisoning patients, and to provide a basis for early prognosis assessment. Methods: October 2021, patients with colchicine poisoning admitted in the First Affiliated Hospitol of Wenzhou Medical University from January 2017 to September 2021 were collected, including general information such as patient gender, age, oral colchicine dose, poisoning time, the first laboratory test index andplasma colchicine concentration after admission. The patients were divided into survival group and death group according to their prognosis. The differences in clinical indicators such as admission plasma colchicine concentration, blood routine, blood biochemistry, coagulation function, and blood gas analysis were compared between the two groups, and their predictive value for the prognosis of patients were analyzed. Results: A total of 23 patients with colchicine poisoning, aged 20-85 years, were included in this study, of which 15 cases (65.22%) survived and 8 cases (34.78%) died. The first plasma colchicine concentration at admision were 0.42-53.61 ng/ml. The plasma colchicine concentration and the concentration-time product were 10.08-2147.04 h·ng/ml.Compared with the survival group, the plasma colchicine concentration and the concentration-time product in the death group were significantly increased, and the differences were statistically significant (P<0.05). Univariate logistic regression analysis showed that first plasma concentration and poisoning time>132.48 h·ng/ml, high C-reactive protein, high D-dimer, high absolute value of BE were the risk factors for the prognosis of patients with colchicine poisoning (OR=12.000, 95%CI: 1.1181-128.836; OR=1.053, 95%CI: 1.009-1.098; OR=1.219, 95%CI: 1.039-1.429; OR=1.360, 95%CI: 1.1.044-1.773; P<0.05). High prothrombin time activity was protective factor affecting the prognosis of colchicine poisoning patients (OR=0.941, 95%CI: 0.892~0.993; P<0.05). ROC curve analysis showed that the areas under the curves of first plasma concentration and poisoning time, C-reactive protein, absolute value of BE, D-dimer for predicting the prognosis of patients with colchicine poisoning were 0.918, 0.888, 0.867, 0.837, respectively, and the areas under the curves of prothrombin time activityfor predicting the prognosis of patients with colchicine poisoning was 0.788 (P<0.05) . Conclusion: The product of the first plasma colchicine concentration at admission and poisoning time is closely related to the prognosis of patients with colchicine poisoning, it can be used as a predictor for early evaluation of the prognosis of poisoned patients.

Abstract
Objective: To investigate the values of serum 8-hydroxydeoxyguanosine (8-OHdG) in predicting disease progression and prognosis of patients with sepsis. Methods: The prospective observational research methods were used. A total of 124 patients with sepsis who met the inclusion criteria were admitted to the Department of Emergency of the First Affiliated Hospital of Wenzhou Medical University from April 2015 to July 2016, including 79 males and 45 females, aged (62±15) years. The sepsis-related organ failure assessment (SOFA) scores of all patients on admission and on the second day of admission and their difference (ΔSOFA) were calculated. The patients were divided into non-progression group with ΔSOFA score <2 (n=101) and progression group with ΔSOFA score ≥2 (n=23), and according to the survival during hospitalization, the patients were divided into survival group (n=85) and death group (n=39). Data of patients between non-progression group and progression group, survival group and death group were compared, including the gender, age, days in emergency intensive care unit (ICU), smoking, hypertension, diabetes mellitus, serum white blood cell count, serum C-reactive protein, and serum procalcitonin on admission, and serum 8-OHdG within 24 h of admission. The multivariate logistic regression analysis was used to screen the independent risk factors of disease progression and death during hospitalization in 124 patients with sepsis, the receiver's operating characteristic (ROC) curves were drawn according to the independent risk factors, and the area under the curve (AUC), the best threshold, and the sensitivity and specificity under the best threshold were calculated. The patients were divided into high 8-OHdG group (n=35) and low 8-OHdG group (n=89) according to the best threshold in ROC curve of death during hospitalization. The data including the gender, age, SOFA score on admission, SOFA score on the second day of admission, and ΔSOFA score of patients in the two groups were compared. The survival rates of patients within 90 d of admission in the two groups were compared by the Kaplan-Meier method. Data were statistically analyzed with independent sample t test, Mann-Whitney U test, chi-square test, and Log-rank test. Results: The gender, age, days in emergency ICU, smoking, complicated with hypertension, complicated with diabetes mellitus, serum white blood cell count, serum C-reactive protein, and serum procalcitonin on admission of patients in non-progression group and progression group were similar (P>0.05). The serum 8-OHdG within 24 h of admission of patients in progression group was significantly higher than that in non-progression group (Z=-2.31, P<0.05). Multivariate logistic regression analysis showed that the serum 8-OHdG within 24 h of admission was the independent risk factor for disease progression of 124 patients with sepsis (odds ratio=1.06, with 95% confidence interval of 1.01-1.11, P<0.05). The AUC under the ROC curve of serum 8-OHdG within 24 h of admission to predict disease progression of 124 patients with sepsis was 0.65 (with 95% confidence interval of 0.52-0.79, P<0.05), the optimal threshold was 32.88 ng/mL, and the sensitivity and specificity under the optimal threshold was 52.2% and 79.2%, respectively. The gender, age, days in emergency ICU, smoking, complicated with hypertension, complicated with diabetes mellitus, and serum white blood cell count, serum C-reactive protein, and serum procalcitonin on admission of patients in survival group and death group were similar (P>0.05). The serum 8-OHdG within 24 h of admission of patients in death group was significantly higher than that in survival group (Z=-2.37, P<0.05). Multivariate logistic regression analysis showed that the serum 8-OHdG within 24 h of admission was the independent risk factor for death of 124 patients with sepsis (odd ratio=1.04, with 95% confidence interval of 1.00-1.09, P<0.05). The AUC under the ROC curve of serum 8-OHdG within 24 h of admission to predict death of patients during hospitalization was 0.63 (with 95% confidence interval of 0.52-0.75, P<0.05), the optimal threshold was 32.43 ng/mL, the sensitivity and specificity under the optimal threshold was 51.3% and 84.7%, respectively. The gender and age of patients in high 8-OHdG group and low 8-OHdG group were similar (P>0.05). The SOFA score on admission, SOFA score on the second day of admission, and ΔSOFA score of patients in high 8-OHdG group were significantly higher than those in low 8-OHdG group (with Z values of -2.49, -3.01, and -2.64, respectively, P<0.05 or P<0.01). The survival rate within 90 d of admission of patients in low 8-OHdG group was significantly higher than that in high 8-OHdG group (χ2=14.57, P<0.01). Conclusions: Serum 8-OHdG level is an independent risk factor for disease progression and death in sepsis patients with limited ability for predicting disease progression and prognosis of sepsis of patients. The patients with higher serum 8-OHdG level have higher death risk within 90 d of admission.

Abstract
OBJECTIVE To compare the safety differences between Chinese medicine (CM) and Western medicine (WM) based on Chinese Spontaneous Reporting Database (CSRD). METHODS Reports of adverse events (AEs) caused by CM and WM in the CSRD between 2010 and 2011 were selected. The following assessment indicators were constructed: the proportion of serious AEs (PSE), the average number of AEs (ANA), and the coverage rate of AEs (CRA). Further comparisons were also conducted, including the drugs with the most reported serious AEs, the AEs with the biggest report number, and the 5 serious AEs of interest (including death, anaphylactic shock, coma, dyspnea and abnormal liver function). RESULTS The PSE, ANA and CRA of WM were 1.09, 8.23 and 2.35 times higher than those of CM, respectively. The top 10 drugs with the most serious AEs were mainly injections for CM and antibiotics for WM. The AEs with the most reports were rash, pruritus, nausea, dizziness and vomiting for both CM and WM. The proportions of CM and WM in anaphylactic shock and coma were similar. For abnormal liver function and death, the proportions of WM were 5.47 and 3.00 times higher than those of CM, respectively. CONCLUSION Based on CSRD, CM was safer than WM at the average level from the perspective of adverse drug reactions.

Abstract
Objective: To investigate the value of serum mitochondrial ATP synthase C subunit level in the evaluation of cardiac functional status and prognosis in patients with sepsis. Methods: A total of 165 sepsis patients admitted to the Emergency Intensive Care Unit (EICU) of the First Affiliated Hospital of Wenzhou Medical University from January 1, 2017 to December 31, 2018 were included, there were 103 males (62.4%) and 62 females (37.6%) with an age of (63±14) years. Human ATP synthase lipid binding protein (ATP5G1) ELISA kit was used to detect the level of serum ATP synthase C subunit within 24 h after admission to EICU, and compared with that in 45 healthy subjects. Clinical data of patients were collected and divided into groups according to different left ventricular ejection fraction (LVEF) and clinical outcomes. The differences in clinical indicators among each group were compared to evaluate the value of serum ATP synthase C subunit level in the evaluation of cardiac functional state and prognosis of patients with sepsis, and the independent risk factors for cardiac functional state and prognosis of patients with sepsis were analyzed. Results: Compared with the control group, the level of serum ATP synthase C subunit in the sepsis group was higher ((116±62) μg/L vs (77±34) μg/L, P<0.001). Compared with normal cardiac function group, the level of serum ATP synthase C subunit in septic cardiac dysfunction group was higher (P<0.001). Compared with the survival group, the level of serum ATP synthase C subunit in the death group was higher (P<0.05). The receiver operating curve (ROC) was drawn to analyze the value of ATP synthase C subunit, creatine kinase isoenzyme (CK-MB), B-type natriuretic peptide (BNP), troponin I (cTnI), left atrial end diastolic diameter, left ventricular end systolic diameter, left ventricular end diastolic volume, left ventricular end systolic volume in evaluating the cardiac function in patients with sepsis, and the area under the curve (AUC) was 0.928, 0.661, 0.837, 0.814, 0.703, 0.831, 0.794 and 0.765, respectively. The cut-off value, sensitivity and specificity of ATP synthase C subunit in it was 139.44 ng/L, 100% and 75.2%, respectively. ROC was drawn to analyze the prognostic value of age, urea nitrogen (BUN), ATP synthase C subunit, APACHEⅡ score and SAPSⅡ score in patients with sepsis, and the AUC was 0.719, 0.772, 0.656, 0.868 and 0.884, respectively. The cut-off value, sensitivity and specificity of ATP synthase C subunit in it was 131.24 ng/L, 61.9% and 68.7%, respectively. Logistic regression analysis showed that age, BUN, ATP synthase C subunit, cardiac dysfunction, APACHEⅡ score and SAPS Ⅱ score were independent risk factors for the prognosis of patients with sepsis. Conclusion: The level of serum ATP synthase C subunit is closely related to cardiac dysfunction in patients with sepsis, and can effectively predict the prognosis of patients with sepsis.

Abstract
Objective: To investigate the role of Orai1-mediated store-operated calcium entry in the immune damage of CD4+ T cells in septic mice. Methods: Sepsis mouse model was established by cecal ligation and puncture(CLP). Balb/c mice of clean grade were sacrificed 1, 3, and 5 days after operation. Spleen samples were harvested at given intervals. Splenic CD4+ T cells were selected by immunomagnetic beads and the expression of Orai1 protein was detected by western blotting, the storage operated calcium entry (SOCE) was detected by flow cytometry, the apoptosis of CD4+ T cells was detected by flow cytometry, the proliferation of CD4+ T cells was detected by CCK-8, and the IFN-γ and IL-4 were detected by enzyme-linked immunosorbent assay (ELISA). Then the expression of Orai1 protein was regulated to further detect the SOCE and immune function of splenic CD4+ T cells in mice. The experiment was divided into 4 groups, sham group, CLP3 group, Orai1 down group (Orai1-down group) and Orai1 up regulation group (Orai1-up group). Results: The relative expression of Orai1 protein in splenic CD4+ T cells in sham group was 1.03±0.16. Compared with sham group, Orai1 protein levels in CLP Group were all significantly lower (F=19.64, P=0.000 5). The increased value of splenic CD4+ T cells fluorescence intensity in sham group was 494±41. Compared with sham group, the levels of SOCE in CLP Group were all lower (F=30.01, P=0.001). The ratio of early and late apoptosis of CD4+ T cells in sham group was 8.7%±1.5%. Compared with sham group, the early and late apoptosis rates of CLP Group were significantly higher (F=32.29, P=0.000 1). The OD of sham group was 0.81±0.10 at 450 nm. Compared with sham group, the proliferation ability of splenic CD4+ T cells in CLP Group were significantly decreased (F=7.26, P=0.001 8). Compared with sham group, the secretion of IFN-γ and IL-4 by CD4+ T cells and the ratio of IFN-γ/IL-4 in CLP Group were all significantly decreased (F=19.690, 6.183, 11.230, all P<0.05). Compared with CLP3 group, the increased value of fluorescence intensity of CD4+ T cells was significantly decreased, the early and late apoptosis ratio of CD4+ T cells was significantly increased, the OD450 nm value of CD4+ T cells was decreased, the multiplication capacity of splenic CD4+ T cells were decreased, the level of IFN-γ and IL-4 secreted by T cells were decreased, and the value of IFN-γ/IL-4 in orai1-down group was decreased (t=4.819, 7.952, 2.988, 28.760, 3.140, 7.670, all P<0.05). However, Orail-up group showed the opposite trend. Conclusion: Orai1-mediated store-operated calcium entry can alleviate the immune dysfunction of CD4+ T cells in septic mice.

Abstract
Vitamin A is easily degraded by environmental factors. Therefore, it is very important to add antioxidants during Vitamin A production. In the past, ethoxyquin (EQ) was widely used, but recent studies have found that it has potential toxicity. Therefore, in this study, we evaluated the antioxidant activities of 4 antioxidants in vitro: EQ, butylated hydroxytoluene, α-tocopherol and L-ascorbic acid sodium salt (Vitamin C sodium). In vitro experiments showed that Vitamin C sodium had better antioxidant capacity. Then, we explored the effects of different antioxidant types of Vitamin A on the growth performance, immune function and antioxidant capacity of weaned pigs. In total, 288 weaned piglets with an initial mean BW of 8.34 ± 0.02 kg at 30 days old were randomly divided into three groups with four replicates and 24 piglets per replicate for 35 days of feeding. The experimental diets were as follows: i) basal diet without external Vitamin A (NC); ii) basal diet supplemented with 12000 IU/kg EQ Vitamin A and iii) basal diet supplemented with 12000 IU/kg Vitamin C sodium Vitamin A. On day 36, two pigs from each replicate were selected to collect serum samples. The in vivo results showed that pigs in the EQ Vitamin A and Vitamin C sodium Vitamin A groups had significantly higher final weight and average daily gain (P < 0.05). During the trial, the levels of IgG and glutathione peroxidase in the EQ Vitamin A and Vitamin C sodium Vitamin A groups were significantly higher than those in the NC group (P < 0.05), and the malondialdehyde content was significantly lower (P < 0.05). On the 36th day, the levels of IgA and total antioxidant capacity in the Vitamin C sodium Vitamin A group were significantly higher than those in the EQ Vitamin A and NC (P < 0.05) groups. Thus, Vitamin C sodium Vitamin A can significantly improve the growth performance, antioxidant capacity and immune function of weaned pigs. Meanwhile, Vitamin C sodium may replace EQ as an antioxidant additive for Vitamin A.

Abstract
Phenoloxidases (POs) are required for the pea aphid's defense against bacterial and fungal infection. Prophenoloxidases (PPOs) are proteolytically converted to its active form PO through a clip domain serine protease cascade. In this study, we identified five clip domain serine proteases in the pea aphids. The messenger RNA levels of two of them, Ap_SPLP and Ap_VP, were upregulated by Gram-positive bacterium Staphylococcus aureus and fungus Beauveria bassiana infections. Double-stranded RNA-based expression knockdown of these two genes resulted in reduced PO activity of the aphid hemolymph, higher loads of S. aureus and B. bassiana in the aphids, and lower survival rates of the aphids after infections. Our data suggest that Ap_SPLP and Ap_VP are involved in PPO activation pathway in the pea aphid.

Abstract
Climate change seriously affects the geographical distribution of plants. Regional diffe-rences in plant response to climate change will provide important guidance for species introduction and conservation. Based on ArcGIS and MaxEnt model, we used 176 geographic information of Carpinus cordata and 13 climatic variables to reconstruct its current and future niche. The results showed that the model had a high credibility in simulating contemporary potential distribution areas. The AUC values of the test set and the training set of the model were 0.973 and 0.957, respectively. The main core suitable areas were concentrated in Qinling, Changbai Mountain and their adjacent areas, with other sporadic "island" distribution. C. cordata is not distributed in Guizhou, Jiangxi, Yunnan and Fujian, but the model predicted some suitable distribution areas in those provinces. With climate warming in the future, ecologically suitable areas of C. cordata would increase significantly, mainly as "shrinking to high altitude areas", "expanding northward", and "expanding eastward". However, core suitable areas would be slightly reduced, which would be manifested as "shrinking southward", "moderate stability", and "expanding northward". The response of C. cordata distribution to climate warming was obviously regional. Eastern Jiangsu, Anhui, and other places would become ecologically suitable areas for C. cordata because of their unique geographical location and climatic environment. The lower latitudes of the south, the original low-altitude areas might no longer be suitable for survival. The central Qinling region was a transition region from north to south, with strong buffer capacity, and climate warming had little effect on its distribution area. The Changbai Mountain and its adjacent areas at higher latitudes were more suitable for C. cordata.

Abstract
Objective: To investigate the protective effect of Baicalin on apoptosis induced by lipopolysaccharide in H9C2 cardiomyocytes and its possible mechanism. Methods: In order to establish apoptosis model of H9C2 cardiomyocytes, H9C2 cardiomyocytes were cultured and divided into four groups: the control group; the baicalin group was treated with baicalin at the final concentration of 10μmol/L for 12 hours; the LPS group was stimulated with LPS at the final concentration of 1 μg/ml for 6 hours; The LPS+baicalin group was stimulated with LPS at the final concentration of 1 μg/ml for 6 hours within treated with baicalin at the final concentration of 10μmol/L for 12 hours. Collecting cell samples, CCK-8 (The Cell Counting Kit-8) was used to detect cell activity, and Terminal-deoxynucleoitidyl Transferase Mediated Nick End Labeling (TUNEL) was used to detect the expression levels of apoptosis. Laser Scanning Confocal Microscopy was used to detect the expression levels of store-operated calcium entry in H9C2 cardiomyocytes. Western blot was used to detect the protein expression levels of STIM1, cleaved-caspase3, Bax and Bcl-2. Fluorogenic quantitative PCR was used to detect the mRNA expression level of STIM1. Results: Compared with the control group, LPS-induced H9C2 cardiomyocyte survival rate decreased (P<0.05), the expression level of apoptosis increased (P<0.05), the internal flow of calcium increased (P<0.05), the expression levels of cleaved-caspase3, Bax protein levels increased (P<0.05), Bcl-2 protein level decreased (P<0.05), the expression of STIM1 mRNA and protein level increased (P<0.05). Compared with LPS group, the survival rate of H9C2 cardiomyocytes in baicalin intervention group increased (P<0.05), the expression level of apoptosis decreased (P<0.05), the internal flow of calcium decreased (P<0.05), the expression levels of cleaved-caspase3, Bax protein decreased (P<0.05), and the level of Bcl-2 protein increased (P<0.05), the expression of STIM1 mRNA and protein level decreased (P<0.05). Conclusion: Baicalin may alleviate LPS-induced cardiomyocyte apoptosis by alleviating calcium overload, and improve cell survival.

Abstract
Objective: To analyze the clinical characteristics, treatment and prognosis of rhabdomyolysis (RM) caused by acute poisoning.Summarize the clinical characteristics and treatment experience, pay attention to the complications and improve the quality of rescue. Methods: We collecte and summarize the clinical data, treatment and prognosis of 22 cases of RM caused by acute poisoning. Results: We found that 21 patients (95.5%) had muscle damage, 13(59.1%) with coma, 8(36.4%) with brown, tea or even soy sauce urine, 6(27.3%) had acute renal injury (AKI), and 4(18.2%) had multiple organ dysfunction syndrome (MODS). After the treatment, 21 cases (95.5%) got better, and one case were discharged. All the patients with AKI were survived, three of them were treated by hemodialysis, and the other recovered gradually after massive fluid replacement. Conclusion: Acute poisoning combined with RM is not uncommon in clinic. We should pay attention to examination of serum enzymes and other indicators, observe the clinical symptoms and make early diagnosis. The key to diagnosis and treatment is early fluid resuscitation, comprehensive treatment, blood purification and maintain the stability of water and electrolyte.

Abstract
Many Salicaceae s.l. plants are recognized for their important role in the production of products such as wood, oils, and medicines, and as a model organism in life studies. However, the difference in plastid sequence, phylogenetic relationships, and lineage diversification of the family Salicaceae s.l. remain poorly understood. In this study, we compare 24 species representing 18 genera of the family. Simple sequence repeats (SSRs) are considered effective molecular markers for plant species identification and population genetics. Among them, a total of 1798 SSRs were identified, among which mononucleotide repeat was the most common with 1455 accounts representing 80.92% of the total. Most of the SSRs are located in the non-coding region. We also identified five other types of repeats, including 1750 tandems, 434 forward, 407 palindromic, 86 reverse, and 30 complementary repeats. The species in Salicaceae s.l. have a conserved plastid genome. Each plastome presented a typical quadripartite structure and varied in size due to the expansion and contraction of the inverted repeat (IR) boundary, lacking major structural variations, but we identified six divergence hotspot regions. We obtained phylogenetic relationships of 18 genera in Salicaceae s.l. and the 24 species formed a highly supported lineage. Casearia was identified as the basal clade. The divergence time between Salicaceae s.l. and the outgroup was estimated as ~93 Mya; Salix, and Populus diverged around 34 Mya, consistent with the previously reported time. Our research will contribute to a better understanding of the phylogenetic relationships among the members of the Salicaceae s.l.

Abstract
Objective: To analyze the epidemiological characteristics, trend and related factors of tuberculosis patients that delayed for care, in Wuhan from 2008 to 2017. Methods: Data regarding tuberculosis (TB) patients was collected from the tuberculosis management information system (TMIS), a part of the China information system for disease control and prevention from 2008 to 2017. A total of 64 208 tuberculosis patients, aged 0 to 95 years were included for the analysis. Unconditional logistic regression method was used to estimate those factors that associated with this study. Results: Days of delay among TB patients appeared as M=10 (P(25)-P(75): 3-28) day, in Wuhan, 2008-2017. The prevalence of the delay was 52.5% (33 703/64 208), presenting a downward trend from 2008 to 2017 (trend χ(2)=10.64, P<0.001), but the proportions of women and ≥65 year-olds were gradually increasing. Results from the multivariate logistic regression analysis showed that factors as: patients living far away from the city vs. near the city (OR=1.29, 95%CI: 1.25-1.35), and age above 45 years vs. younger than 25 years (the age 45-64 years group vs. aged less than 25 years group, OR=1.22, 95%CI: 1.15-1.29; the age 65 or above group vs. aged less than 25 years group, the OR=1.30, 95%CI: 1.22-1.39) were under higher risk on the delay of seeking care. Occupation, way of case-finding and classification of tuberculosis patients also appeared as influencing factors on this issue. Conclusions: Prevalence on the delay of care was 52.5% among tuberculosis patients in Wuhan, 2008-2017, but with an annual decrease. Attention should be paid to female, wrinkly or elderly tuberculosis patients regarding the delay of care on TB, in Wuhan.

Abstract
Objective: To investigate the effects of mono-carbonyl analogues of curcumin (L6H21) on paraquat (PQ) -induced injury in HK-2 cell line and explore its underlying mechanisms. Methods: Cultured HK-2 cells were challenged by PQ with or without L6H21 treatment. Cell viability and apoptosis were determined by CCK-8 assay and flow cytometry, respectively. Gene expressions and protein levels of apoptotic and inflammatory factors were assessed by RT-PCR, ELISA, and western blot. Intracellular ROS production was detected by DCFH-DA staining. Superoxide dismutase (SOD) and malondialdehyde (MDA) were examined by chemical colorimetry. Results: 1) PQ challenge significantly inhibited HK-2 cells proliferation, which was prevented by L6H21 administration. PQ dramatically induced HK-2 apoptosis evidenced by increasing expressions of caspase-9, caspase-3 and Bax, while decreasing Bcl-2 level. However, PQ induced these apoptotic effects in HK-2 cells were reversed by L6H21. Similarly, PQ exposure obviously enhanced activity of NF-κB and levels of cytokines (TNF-α、IL-6) in HK-2 cells, which was inhibited by L6H21. Furthermore, administration of L6H21 inhibited PQ induced ROS and MDA production, and promoted SOD level in HK-2 cells. Conclusion: L6H21 administration inhibits PQ-induced apoptosis in HK-2 cells possibly by reducing inflammation and oxidative damage.

Abstract
OBJECTIVE Type 2 diabetes mellitus is increasing in young adults, and greater adiposity is considered a major risk factor. However, whether there is an association between obesity and diabetes and how this might be impacted by age is not clear. Therefore, we investigated the association between body mass index (BMI) and diabetes across a wide range of age groups (20-30, 30-40, 40-50, 50-60, 60-70 and ≥70 years old). DESIGN We performed a retrospective cohort study using healthy screening programme data. SETTING A total of 211 833 adult Chinese persons >20 years old across 32 sites and 11 cities in China (Shanghai, Beijing, Nanjing, Suzhou, Shenzhen, Changzhou, Chengdu, Guangzhou, Hefei, Wuhan, Nantong) were selected for the study; these persons were free of diabetes at baseline. PRIMARY AND SECONDARY OUTCOME MEASURES Fasting plasma glucose levels were measured and information regarding the history of diabetes was collected at each visit. Diabetes was diagnosed as fasting plasma glucose ≥7.00 mmol/L and/or self-reported diabetes. Patients were censored at the date of diagnosis or the final visit, whichever came first. RESULTS With a median follow-up of 3.1 years, 4174 of the 211 833 participants developed diabetes, with an age-adjusted incidence rate of 7.35 per 1000 persons. The risk of incident diabetes increased proportionally with increasing baseline BMI values, with a 23% increased risk of incident diabetes with each kg/m2 increase in BMI (95% CI 1.22 to 1.24). Across all age groups, there was a linear association between BMI and the risk of incident diabetes, although there was a stronger association between BMI and incident diabetes in the younger age groups (age×BMI interaction, p<0.0001). CONCLUSIONS An increased BMI is also independently associated with a higher risk of developing diabetes in young adults and the effects of BMI on incident diabetes were accentuated in younger adults.

Abstract
PURPOSES Abnormal islet microcirculation impetus the insulin production and accelerates progression of Type 1 and 2 diabetes. In this study, we investigated whether tetramethylpyrazine phosphate (TMPP), a vasoactive substance, could regulate the islet microcirculation and insulin concentration and improve glycaemia in SD rats. METHODS SD rats were randomly divided into two groups, the control and TMPP groups. Each group was further divided into three subgroups according to the intravenous injection of either saline, 15 or 30% glucose. The non-radioactive microsphere technique was adopted to measure the organ blood flow. Nitric oxide synthase (NOS) blocker L-NAME was used to address whether NO was involved in mediating the vasoactive effects of TMPP. RESULTS In the TMPP group, TMPP increased the PBF (pancreatic blood flow), IBF (islet blood flow), and fIBF (fraction of islet blood flow out of pancreatic blood flow) by 57, 76 and 47%, respectively, after 30% glucose infusion, compared with the control, indicating that TMPP could regulate islet microcirculation. Furthermore, TMPP induced a 66% elevation of IBF and 37% of fIBF in the 30% glucose subgroups than the 15% ones. In 30% glucose-treated subgroups, TMPP improved the blood glucose concentration by 10%, compared with the control (19.3 ± 0.64 vs 17.32 ± 0.56 mmol/l, P < 0.05), without influencing the insulin secretion. Blocking NO formation prevented the enhanced PBF and IBF, evoking by TMPP with 30% glucose. CONCLUSIONS TMPP can regulate the pancreatic islet microcirculation and possess a hypoglycemia effect after glucose infusion through affecting the islet microcirculation.

Abstract
Objective: To explore the risk factors influencing the prognosis of elderly patients with acute poisoning. Methods: We retrospected 177 elderly patients with Acute Poisoning who were treated in the emergency department of the first affiliated hospital of wenzhou medical university from July 2009 to May 2015. According to the outcome of patients, we distributed the patients to death group (31 cases) and survival group (146 cases) , compared the clinic data and using multivariate analysis with Logistic regression to prognosis factors. Results: There were 177 cases in total, with 146 survivors (82.5%) and 31 deaths (17.5%) . In which 102 cases (57.6%) had chronic underlying diseases. There were 28 cases of pesticide poisoning in the death group, and the fatality rate of pesticide poisoning was 23.5%. The mortality rate was 12.8% in the 60-69 years-old group (11/86) , 20% (13/65) in the 70-79 years-old group, 26.9% (7/26) in the 80-89 years-old group. The most common reason of poisoning was intentional ingestion, with 100 cases (56.5%) . The tract of the poisoning was mainly in digestive system, including 148 cases (83.6%) . The PSS score and APACHE-II score were 2.97±0.18 and 19.8±2.8 in the death group, 2.27±0.81 and 12.8±5.3 in the survival group. Compared with the survival group, poison (pesticides or non) 、poisoning route、cause of poisoning、PSS score、APACHEⅡ score have significant difference in death group (P<0.05) . Poison (pesticides or non) 、PSS score、APACHEⅡ, were the independent risk factors of poor prognosis. Conclusion: Most of the elderly patients with acute poisoning have one or more chronic underlying diseases, the digestive tract ingestion and pesticide poisoning are more common. The fatality rate of the old patients is significantly higher than that of non elderly poisoning. Type of toxications, PSS score and APACHE-II score are the prognostic factors in elderly patients.

Abstract
Objective: To investigate the protective effect of P-glycoprotein up-regulated by ulinastatin (UTI) on HK-2 cells during paraquat (PQ) -induced injury and its underlying mechanisms. Methods: The re- search was divided into two parts. The first part of the research was divided into normal control group, PQ group, UTI+PQ group, UTI control group. The second part of the research was divided into negative virus group (including control group, PQ group, PQU+TI group, UTI group) and P-gp siRNA group (including control group, PQ group, PQU+TI group, UTI group) . Negative virus group: the cells were transfected into the blank virus; siRNA P-gp group: the cells were transfected with P-gp siRNA virus. HK-2 cells were routinely cultured. After 800 μmol/L PQ treatment, the changes of P-gp protein levels in the HK-2 cells were determined by West-ern-blot (WB) . Then, transfected lentivirus bringing P-gp silent gene, the cell viability was determined by CCK-8 assay, the expression of P-gp in the cells after transfection was detected by WB and the concentration of PQ in HK-2 cells were measured by high performance liquid chromatography (HPLC) . Results: Compared with the normal control group, the P-gp expression of PQ group had no significantly changes (P>0.05) . Compared with the PQ group, the P-gp expression of UTI+PQ group significantly increased (P>0.05) . Compared with the corre-sponding control siRNA group, the P-gp siRNA group had no significantly changes in cell viability (P>0.05) . and significantly decreased in P-gp expression. Compared with the corresponding control siRNA group, the P-gp siRNA group had no significantly changes in PQ concentration in HK-2 cell (P>0.05) , but compared with P-gp siRNA PQ group, the PQ concentration of P-gp siRNA PQ+UTI group significantly decrease (P<0.05) . Conclusion: UTI significantly reduced the accumulation of PQ in HK-2 cells and increased the viability of HK-2 cells in vitro may be not by increased P-gp activity. UTI could significantly reduce HK-2 cell injury induced by PQ in vitro and improve the survival rate of HK-2 cells. It may not be related to the up regulation of P-gp expres-sion.

Abstract
As meat quality is basically dependent on muscle fibre characteristics, it is important to know how muscle fibres are regulated and transformed. This study aimed to investigate the effect of maternal dietary supplementation on muscle fibre types using 3% saturated fatty acid (palmitic acid, PA) or 3% unsaturated fatty acid (linoleic acid, LA) from 80 days of gestation to the weaning of offspring (25 days post-natal). The results indicated that higher mRNA levels of MyHCI type genes were found in the soleus muscles of piglets that suckled from LA-supplemented sows than from PA-supplemented sows. In addition, LA treatment increased the gene expression of the type I muscle fibre marker troponin I (p < 0.01), suggesting that LA promoted muscle fibre type transformation to type I fibres. Moreover, PGC-1α (p < 0.01) and MEF2c (p < 0.05) mRNA levels were higher in the piglets from the LA treatment group than in those from the PA treatment group. Furthermore, LA supplementation also significantly increased AMP-activated protein kinase (AMPK) mRNA levels (p < 0.05), which is an upstream regulator of PGC-1α. Collectively, these findings demonstrated that maternal dietary LA supplementation promoted muscle fibre transformation to type I fibre and that this process may be mediated through an AMPK-dependent pathway.

Abstract
More and more studies demonstrated that β2 adrenergic receptor (β2-AR) plays a crucial role for the treatment of heart failure. Chuanwu and Fuzi have been used over thousands of years in China for the treatment of heart failure. Considering the effects of these herbs are very similar to β2-AR agonists, we presume whether β2-AR agonists can be found from Fuzi and Chuanwu. Fuzi and Chuanwu decoction were used to receive the luciferase reporter activity assay to verify the hypothesis, and the result is positive and encouraging. For it is very difficult to get all of the monomer compounds of Fuzi and Chuanwu, virtual screening was used to find potential β2-AR agonists and a cell-based β2-AR agonist functional evaluation model, combined with a luciferase reporter assay system, was used to confirm the final result. In this research, 45 compounds were identified as β2-AR agonists, and four compounds were verified and the rest need further experiment.

Abstract
Resistin (RSTN) expression in subcutaneous adipose tissue, and its effect on glucose metabolism in rats with traumatic brain injury, was investigated using real-time PCR, western blots, and enzyme linked immunoassays. Our results show that the expression of RSTN mRNA (3.192 ± 0.046, 4.016 ± 0.010, 6.004 ± 0.020, 8.213 ± 0.013, 11.199 ± 0.174, 15.094 ± 0.030), protein levels (1.79 ± 0.05, 1.98 ± 0.07, 2.75 ± 0.08, 3.19 ± 0.08, 4.25 ± 0.11, 4.48 ± 0.07), levels of serum insulin (512.96 ± 1.21, 580.57 ± 1.52, 769.71 ± 2.22, 826.08 ± 2.03, 1262.25 ± 3.40, 1512.80 ± 3.93), and fasting blood glucose levels (10.277 ± 0.040, 12.776 ± 0.038, 13.403 ± 0.263, 14.698 ± 0.100, 16.637 ± 0.110, 19.416 ± 0.025) were significantly higher in the traumatic rat group compared to the control group (P < 0. 05). Quantitative insulin sensitivity check index (QUICKI) was significantly lower in the traumatic group (-8.570 ± 0.005, -8.912 ± 0.004, -9.241 ± 0.022, -9.404 ± 0.007, -9.952 ± 0.007, -10.288 ± 0.002) than in the control group (-7.633 ± 0.003, -7.639 ± 0.004, -7.637 ± 0.006, -7.643 ± 0.003, -7.636 ± 0.006, -7.634 ± 0.004) (P < 0.05). Single factor linear correlation analysis showed that there was a significant negative correlation between RSTN expression and QUICKI (-0.983, P < 0.05) in the traumatic group. The increase in RSTN expression in the subcutaneous adipose tissue of rats with traumatic brain injury is likely related to the indexes of glycometabolism, including serum insulin, fasting blood glucose, and QUICKI. Our results lead us to conclude that RSTN may play an important role in the process of insulin resistance in rats with traumatic brain injury.

Abstract
PREMISE OF THE STUDY A set of expressed sequence tag (EST) microsatellite markers were developed and characterized using next-generation sequencing technology for the Chinese genus Ostryopsis (Betulaceae). • METHODS AND RESULTS A total of 38 high-quality simple sequence repeat (SSR) primers were identified, of which 15 could be successfully amplified. Subsequently, we selected 80 individuals to represent the three species of the genus to evaluate the efficacy of these markers for examining genetic diversity of each species in the future. We found that the number of alleles per locus ranged from one to nine, with an average of 3.8. The expected heterozygosity and observed heterozygosity per locus varied from 0 to 0.829 and from 0 to 1, respectively, with their respective mean values as 0.483 and 0.416. • CONCLUSIONS These EST-SSR markers will be useful for evaluating the range-wide genetic diversity of each species and examining genetic divergence and gene flow between the three species.

Abstract
Liquorice (root of Glycyrrhiza uralensis Fisch.) is an important Chinese traditional medicine for many ailments (4). From 2002, severe outbreaks of root rot occurring on cultivated G. uralensis plants in Ningxia, China, have affected the yield and quality of liquorice and been considered as a major threat to commercial production of liquorice. Approximately 30% of the plants die from this disease in Ningxia every year. The disease, mainly affecting 2- to 4-year-old G. uralensis seedlings, begins with brown rot of root tips or lateral roots followed by internal decay of taproots during June to August every year. The infected plants are wilted with chlorotic foliage and easily pulled up from the soil. Root rot is clearly visible as a severe brown discoloration of vascular tissue along taproots. In severe cases, white mycelia are clearly visible on the surface of diseased roots and roots are decomposed. Isolations from diseased roots were made on potato dextrose agar (PDA) amended with streptomycin sulfate. Isolates (n = 78) were recovered from symptomatic roots (n = 105) and pure cultures were established by the single spore method. The two most frequently isolated fungi were transferred to potato sucrose agar and identified as Fusarium solani (61.5%) and F. oxysporum (30.8%) (1). The monophialides bearing microconidia of F. solani are long when compared to those of F. oxysporum. Genomic DNA of strains F. solani G013 and F. oxysporum FLR were extracted from mycelia with the cetyltrimethylammonium bromide (CTAB) method. Primers EF1-728F and EF1-986R were used to amplify the translation elongation factor-1α (TEF-1α) gene (2). The TEF-1α sequences of F. solani G013 (GenBank Accession No. AB777258) and F. oxysporum FLR (AB777257) shared 99 and 100% similarity with F. solani isolate NRRL52790 and F. oxysporum isolate NRRL 38328, respectively. Pathogenicity tests with one representative isolate of each species were conducted in the greenhouse on 1-month-old potted G. uralensis seedlings (12 plants per treatment). Isolates of the tested fungi were transferred to PDA and incubated in darkness at 24 ± 1°C for 7 days. Plant taproots about 5 cm below the soil surface were wounded with a sterile needle and five 5-mm-diameter fungal disks on the margin of colony were taken and firmly placed on the wounded location of each taproot with tinfoil; wounded taproots of seedlings inoculated with sterile PDA disks were used as controls (3). Root rot was assessed 2 months after inoculation. F. solani G013 and F. oxysporum FLR produced root rot symptoms on inoculated plants that were the same as those observed in field plants, and the fungi were reisolated from roots with typical symptoms. Control plants inoculated with sterile PDA disks remained asymptomatic, and no pathogen was isolated from them. To our knowledge, this is the first report of root rot caused by F. solani and F. oxysporum on G. uralensis in China. Effective control strategies are needed to minimize losses. References: (1) C.

Abstract
Type 2 diabetes mellitus is a risk factor for coronary artery disease (CAD). While there is a clear association of fasting plasma glucose (FPG) with microvascular complications, the risk for CAD conferred by FPG is relatively less clear. Therefore, we investigate the association between different FPG and the prevalence and severity of angiographic CAD in high-risk Chinese patients without known diabetes. Among 1,419 subjects who were to undergo coronary angiography for the confirmation of suspected myocardial ischemia, 906 subjects without known diabetes were included in this study and categorized into four groups according to the level of FPG: group 1, ≤5.5 mmol/l; group 2, 5.6-6.0 mmol/l; group 3, 6.1-6.9 mmol/l; and group 4, ≥7.0 mmol/l. Significant angiographic CAD was defined as ≥50 % lumen diameter reduction in at least one major coronary artery in a given subject. The severity and extent of coronary atherosclerosis were defined as the number of diseased vessels, the proportion of totally occluded vessel and the Gensini score. Associations between FPG and the prevalence and severity of CAD were assessed by logistic and linear stepwise regression analyses. The angiographic CAD prevalence, the number of diseased vessels, the totally occluded vessel, and the Gensini score increased corresponding to increasing FPG levels from ≤5.5 mmol/l to 5.6-6.0 mmol/l to 6.1-6.9 mmol/l to ≥7.0 mmol/l (P < 0.05). The FPG had significant association with angiographic CAD (adjusted OR, 1.53; 95 % CI, 1.19-1.98; P = 0.001) and the Gensini score (standardized regression coefficient = 0.172, P = 0.011). Compared with group 1, group 2, 3 and 4 demonstrated significantly higher CAD prevalence after adjustment (adjusted OR, 1.61 [1.16-2.19]; P = 0.015 for group 2; 1.49 [1.11-2.59]; P = 0.027 for group 3; and 4.19 [2.85-6.16]; P = 0.024 for group 4, respectively). FPG group was also significantly associated with the Gensini score (Standardized coefficients, 0.185; P = 0.007, respectively). FPG was an independent risk factor for the prevalence and severity of significant angiographic CAD in our study population. The severity of angiographic CAD increased along with the increasing FPG levels even in prediabetic state.

Abstract
Mycothiol (MSH) plays important roles in maintaining cytosolic redox homeostasis and in adapting to reactive oxygen species in the high-(G + C)-content Gram-positive Actinobacteria. However, its physiological roles are ill defined compared to glutathione, the functional analog of MSH in Gram-negative bacteria and most eukaryotes. In this research, we explored the impact of intracellular MSH on cellular physiology by using MSH-deficient mutants in the model organism Corynebacterium glutamicum. We found that intracellular MSH contributes significantly to resistance to alkylating agents, glyphosate, ethanol, antibiotics, heavy metals and aromatic compounds. In addition, intracellular MSH is beneficial for withstanding oxidative stress induced by various oxidants in C. glutamicum. This study greatly expanded our current knowledge on the physiological functions of mycothiol in C. glutamicum and could be applied to improve the robustness of this scientifically and commercially important species in the future.

Abstract
BACKGROUND Recent studies revealed that baicalin, a flavonoid compound derived from the root of Scutellaria baicalensis Georgi, could promote neuron differentiation of NSPCs after commencing the differentiation process in vitro. However, this may not be the most efficacious strategy to determinate cell fate. Here, we have investigated whether baicalin can influence early events of neuron generation and stimulate adult neurogenesis. RESULTS Transient exposure of NSPCs to baicalin during proliferation could activate Mash1 to alter the differential fate and increase the proportion of cells expressing neuronal markers. Seven days after, rats were exposed to transient cerebral ischemia, they were treated for 3 weeks with baicalin, BrdU labeling study showed that exposure to baicalin increased the number of newly generated cells in hippocampus, BrdU/NeuN double staining analysis indicated that baicalin could promote new neuron production after cerebral ischemia. Additionally, Morris water maze test showed that delayed postischemic treatment with baicalin improved cognitive impairment. CONCLUSIONS These results identify the existence of a single molecule, baicalin, which can specify the neuronal fate of multipotent NSPCs and stimulate neurogenesis, making it a promising candidate for developing clinically relevant strategies to manipulate neuronal fate of NSPCs for brain repair.

Abstract
Proprotein convertase subtilisin/kexin-type 1 (PCSK1) is a prohormone convertase that has an important role in prohormone maturation including the process of prorenin to renin. We studied the association of the PCSK1 single-nucleotide polymorphism (SNP) rs6235 (encoding an S690T substitution) with essential hypertension (EH), obesity and related traits in the Han Chinese population. The rs6235 SNP in the PCSK1 gene was investigated using a case-control study design, with 1034 hypertension cases and 1112 normotensive controls. In this study, the rs6235 SNP was significantly associated with hypertension (OR=1.26, 95% CI (1.10-1.46), P=0.001); the odds ratios of GC vs GG and CC vs GG were 1.30 (95% CI (1.06-1.58), P=0.010) and 1.55 (95% CI (1.12-2.13), P=0.007), respectively. In the controls, the C-allele was associated with increased systolic (P=0.010) and diastolic (P=0.010) blood pressure levels. In all of the EH patients and EH patients without a history of renin-angiotensin-aldosterone (RAA) system-related antagonists, the C-allele was associated with increased plasma renin activity (P=0.00004 and 0.002, respectively) and aldosterone levels (P=0.018 and 0.005, respectively). The C-allele was also associated with increased body mass index (BMI) (P=0.010) in the normotensive controls. In conclusion, the PCSK1 SNP rs6235 was associated with EH and blood pressure in the Han Chinese population, and this association may be mediated by the SNP's effect on RAA levels. rs6235 was also associated with BMI in this population.
