Objective:To study the antihyperglycemic effect of water soluble polysaccharides (MCW) and alkaline soluble polysaccharides (MCB) from Momordica charantia L. on streptozotocin-induced diabetic mice. Method:Twelve mice were selected randomly as control, while the other l08 mice were injected with STZ 200 mg/kg?bw to induce diabetes.The diabetic mice were divided into 4 groups,the model, MCW (300 mg/kg bw), MCB (300 mg/kg bw), Gilbenclamide (15 mg/kg bw). The above components were administered intragastrically for 10 d and then blood samples were taken to determine concentrations of serum glucose and insulin. Results: The blood glucose levels could be obviously decreased by MCW and MCB in the diabetic mice. MCB has the best antihyperglycemic effect, in terms of improving the serum insulin level and decreasing the blood glucose level of diabetic mice. Conclusion:The polysaccharides from Momordica charantia can repair the injured pancreatic islet tissues and enhance insulin secretion so as to reduce blood glucose level of the diabetic mice.

Objective: To establish a ultra-high performance liquid chromatography-tandem triple quadrupole mass spectrometry method for rapid simultaneous determination of quinclorac, acetochlor, butachlor and metolachlor in urine. Methods: Urine samples were diluted 10 times, prepared into the mixed standard solution, and subjected to gradient elution on the ACQUITY UPLC BEH C18 column (100 mm×2.1 mm, 1.7 μm) with 0.1% formic acid and acetonitrile as the mobile phase. The quinclorac, acetochlor, metolachlor and butachlor levels were determined using electrospray ionization-positive ultra-high performance liquid chromatography-tandem triple quadrupole mass spectrometry with the multiple reaction monitoring mode. Results: Four herbicides were effectively separated on the ACQUITY UPLC BEH C18 column (100 mm× 2.1 mm, 1.7 μm), and good linear relationships were observed for quinclorac, acetochlor and butachlor at 1 to 25 μg/L and for metolachlor at 0.2 to 25 μg/L, with all linear correlation coefficients of >0.999. The detection limts of quinclorac, acetochlor, butachlor and metolachlor were 0.10, 0.10, 0.20 and 0.01 μg/L, respectively. The recovery rates of quinclorac, acetochlor and butachlor were 107.42%, 93.94% and 90.27% from urine samples at a spiked level of 5 µg/L, with relative standard deviations of 4.82%, 3.84% and 6.76%, and the recovery rate of metolachlor was 89.51% at a spiked level of 0.5 µg/L, with a relative standard deviation of 8.98%. Conclusion The chromatography and mass spectrometry conditions are optimized in this ultra-high performance liquid chromatography-tandem mass spectrometry, which is effective for rapid simultaneous determination of quinclorac, acetochlor, metolachlor and butachlor in urine samples.

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease which is associated with genetic and environmental factors, though the pathogenesis is still unclear and there is also a lack of effective treatment. With the rapid advance of genetic testing techniques, over 30 genes have been associated with the disease. Some ALS patients harboring genetic variants may present unique clinical characteristics and particular mode of inheritance, but the correlation between genotype and phenotype is still not very clear. Studies have shown that research on the pathogenic genes of ALS is important for the diagnosis and selection of potential drug targets. Here the pathogenic genes of ALS, in particular the newly discovered genes, and their underlying mechanisms are reviewed. The necessity of genetic testing for ALS patients is also stressed.

OBJECTIVETo identify the mutation of the GABA(A)-receptor gamma 2 subunit gene (GABRG2) in a Chinese family with generalized epilepsy with febrile seizures plus (GEFS+ ) and analyze the genotype-phenotype correlations and its inheritance.

METHODSGenomic DNA was extracted from peripheral blood lymphocytes of the proband and other available members in the GEFS+ family. The coding regions and flanking intronic regions of the GABRG2 gene were screened for mutations using polymerase chain reaction (PCR) and direct DNA sequencing.

RESULTSThere were 7 affected members in the three-generation family, in which one with febrile seizures (FS) and six with febrile seizures plus (FS+ ). This family was consistent with the diagnostic criteria of GEFS+ . The nonsense mutation c.1287G to A (p.W390X) in the GABRG2 gene was initially identified in the proband. Seven affected members (6 FS+ and 1 FS) and one unaffected member carried the mutation. The nonsense mutation c.1287G to A/p.W390X in the GABRG2 gene was co-segregated with the GEFS+ family. The penetrance rate was about 87.5%(7/8).

CONCLUSIONThis GEFS+ family was consistent with autosomal dominant inheritance with incomplete penetrance. GABRG2 mutation is also a disease-causing mutation in Chinese GEFS+ patients. The p.W390X mutation has not been reported previously.

Purpose In order to improve the detection rate and diagnostic accuracy of clinically significant prostate cancer (PCa),prostate imaging reporting and data system version 2 (PI-RADS v2) was introduced to standardize multi-parametric MRI (mp-MRI) assessment classification standard.This study was designed to analyze the missed diagnosis and misdiagnosis of PCa when PI-RADS v2 was used as a diagnosis standard.Materials and Methods With step-section pathology as a "Golden Standard",mp-MR1 data of 52 patients with PCa were retrospectively analyzed,the problems confronted by radiologists when reading films with PI-RADS v2 were summarized,and the emphasis was given on missed diagnosis and misdiagnosis.Results 114 PCa foci were identified through stepsection pathology,including 83 clinically significant PCa.MRI found 91 suspicious lesions,in which 63 were true positive,with the misdiagnosis rate of 30.8％.The rate of missed diagnosis of PCa was 38.6％,and the rate of missed diagnosis of clinically significant PCa was 24.1％.Conclusion There will be relatively high rate of misdiagnosis and missed diagnosis when PI-RADS v2 is used as a diagnostic standard.

Objective To evaluate the predictive value of multiparametric MRI (mpMRI)for extracapsular extension (ECE)in patients with prostate cancer.Methods The imaging of prostate mpMRI was performed in 52 consecutive patients with prostate cancer,who underwent subsequent radical prostatectomy.MR images were interpreted retrospectively by one experienced radiologist, who was blinded to any clinical details.According to Prostate Imaging Reporting and Data System Version 2 (PI-RADS v2),suspecious lesions were graded and recorded.Lesions with PI-RADS≥4 were further categorized in terms of ECE and correlated with radical prostatectomy pathology by using side-by-side comparison.Receiver operating characteristic (ROC)curves were used to calculate accuracy,sensitivity,specificity,positive predictive value(PPV)and negative predictive value(NPV),in order to evaluate diagnostic performance of ECE scoring system.Results Totally 55 prostate cancer foci with PI-RADS≥4 were correctly identified by the radiologist.The area under the ROC of ECE score was 0.694 (P=0.013)and ECE score 3 was considered as the best cutoff point with accuracy,sensitivity,specificity,PPV and NPV of 69.3%, 70.4%,67.9%,67.9% and 70.4%,respectively.Conclusion mpMRI is a relatively reliable noninvasive technique for assessment of ECE in clinical practice.

The mucosal immune system is the first line of defense against pathogens such as bacteria and viruses invading the bodies. The female reproductive tract mucosal immune system not only resists the invasion of pathogens through innate and adaptive immunity, but also contribute to successfully fertilization and pregnancy, thus maintaining the health of women′s reproductive system. The innate immunity of female genital tract involves the mechanical barrier of the mucosal epithelium, microbial barrier of commensal bacteria, immunological barrier of immune cells and their receptors, and adaptive immunity including B cell-mediated humoral immunity and T cell-mediated cellular immunity. Female genital mucosal immunity is not only involved in local inflammation, but may also have anti-tumor effects. Moreover, the female genital tract mucosal immune is also regulated by sex hormone to maintain a homeostasis of local microenvironment. Herein, this paper summarized recent progress in female genital mucosal immunity.

Amyotrophic lateral sclerosis is a neurodegenerative disease caused by the loss of motor neurons in the brain and spinal cord. There is currently no effective cure. The emergence of gene therapy brings hope to treatment, which can be achieved by delivering transgenes to replace or correct defective genes, as well as the expression of neurotrophic factors. The vectors of gene therapy can be viral vectors and non-viral vectors. Lentiviral vectors can be used to deliver therapeutic sequences to motor neurons in the central nervous system. Adeno-associated viruses can effectively mediate gene expression and delivery of neurotrophic factors. Gene editing and antisense oligonucleotides therapy are also perspective treatment options. This article summarizes gene therapy for amyotrophic lateral sclerosis from basic experiments and clinical trials.

Objective To observe the effect of excretory/secretory products from Trichinella spiralis adult worms(AES)on cecal ligation and puncture(CLP)?induced sepsis in mice. Methods Forty?eight BALB/c mice were randomly divided into 3 groups:a sham operation group(PBS+sham group,Group A),a CLP?induced sepsis group(PBS+CLP group,Group B)and an AES treatment group(AES+ CLP group,Group C). The mice of each group were intraperitoneally injected with 25 μg of AES or PBS only as a control in a total volume of 200μl. Eight mice from each group were selected randomly for survival analy?sis of 96 hours. The other 8 mice in each group were observed for pathological changes in the lung,liver and kidney tissues by HE staining 12 h after CLP,and then determined for the detection of cytokines including TNF?α,IL?1β,IL?6,IL?10 and TGF? βin the sera by ELISA. Results The difference among the survival rates of mice in the 3 groups was statistically significant (χ2=21.16,P<0.05). Compared to Group A(100%),the survival rate of mice in Group B(0)decreased significantly(P<0.05),and also the pathological damage degrees in the lung,liver and kidney tissues of the mice in Group B increased signifi?cantly after CLP. Compared with the mice in group B,the survival rate of those in Group C(70%)increased significantly(P<0.05),and the pathological damage degrees in the lung,liver and kidney tissues of the mice in Group C decreased significantly after the treatment with AES. The differences among the levels of pro?inflammatory cytokines TNF?α(F=27.11,P<0.05),IL?1β(F=18.75,P<0.05)and IL?6(F=100.93,P<0.05)in the sera of the mice in the three groups were statistically signifi?cant. Compared with the mice in Group A,the levels of the 3 cytokines of those in Group B increased significantly(all P <0.05). However,after the treatment with AES,the levels of the pro?inflammatory cytokines of those in Group C decreased signifi?cantly(all P<0.05). The differences among the levels of immunoregulatory cytokines IL?10(F=10.88,P<0.05)and TGF?β(F=11.37,P<0.05)in the sera of the mice in the three groups were also statistically significant. Compared with the mice in Group B,the levels of IL?10 and TGF?β of those in Group C were higher after treatment with AES(both P<0.05). Conclu?sion T. spiralis AES has a therapeutic potential for alleviating sepsis induced by CLP in mice.
