AIM To investigate the flavor technology for Jiannaoning Mixture based on electronic tongue combined with preference index.METHODS Artificial sensory evaluation method was employed to screen the type of flavor agents,electronic tongue was applied to screening the consumption of flavor agents,and double-bottle preference test was adopted in the analysis of effects of rat gender and body weight on taste sensitivity,after which acceleration test was conducted.RESULTS Sucrose,stevioside and xylitol were taken as flavor agents,whose optimal consumptions were 15%,0.08%and 15%,respectively.Male rats demonstrated stable taste perception with the body weights of 220-280 g,and 0.08%stevioside displayed the best flavoring effect.After placed under accelerated condition for 3 months,the preparation exhibited stable appearance,pH value and contents of lobetyolin,salvianolic acid B,schizandrin,ruscogenin.CONCLUSION This stable and reliable method can provide reference for improving the terrible tastes of Jiannaoning Mixture and other oral liquid preparations of traditional Chinese medicines.

Variations in the dynein axonemal heavy chain gene, dynein axonemal heavy chain 6 (DNAH6), lead to multiple morphological abnormalities of the flagella. Recent studies have reported that these deficiencies may result in sperm head deformation. However, whether DNAH6 is also involved in human acrosome biogenesis remains unknown. The purpose of this study was to investigate DNAH6 gene variants and their potential functions in the formation of defective sperm heads and flagella. Whole-exome sequencing was performed on a cohort of 375 patients with asthenoteratozoospermia from the First Affiliated Hospital of Anhui Medical University (Hefei, China). Hematoxylin and eosin staining, scanning electron microscopy, and transmission electron microscopy were performed to analyze the sperm morphology and ultrastructure. Immunofluorescence staining and Western blot analysis were conducted to examine the effects of genetic variants. We identified three novel deleterious variants in DNAH6 among three unrelated families. The absence of inner dynein arms and radial spokes was observed in the sperm of patients with DNAH6 variants. Additionally, deficiencies in the acrosome, abnormal chromatin compaction, and vacuole-containing sperm heads were observed in these patients with DNAH6 variants. The decreased levels of the component proteins in these defective structures were further confirmed in sperm from patients with DNAH6 variants using Western blot. After intracytoplasmic sperm injection (ICSI) treatment, the partner of one patient with a DNAH6 variant achieved successful pregnancy. Overall, novel variants in DNAH6 genes that contribute to defects in the sperm head and flagella were identified, and the findings indicated ICSI as an effective clinical treatment for such patients.

Cavernous nerve injury is an important cause of erectile dysfunction (ED). Although protective nerve technology has been widely used in nerve-sparing radical prostatectomy (nsRP), the incidence of ED is still very high after surgery. The purpose of our study was to evaluate erectile function (EF) and penile length in the non-erectile state (PLNES) following scheduled phosphodiesterase 5 inhibitor (PDE5i), vacuum erectile device (VED) treatment, and combination therapy after nsRP. One hundred patients with localized prostate cancer and normal EF were randomized to scheduled PDE5i group, VED treatment group, a combined treatment group, and the control group without any intervention. The International Index of Erectile Function-5 (IIEF-5) scores and PLNES were evaluated after 6 months and 12 months of treatment. Sexual Encounter Profile (SEP-Question 2 and SEP-Question 3) were evaluated after 12 months of treatment. Ninety-one of the 100 randomized patients completed the study. We found that the 5 mg tadalafil once a day (OaD) combined with VED can help improve IIEF-5 scores in nsRP patients after both 6 months and 12 months. VED alone or combined with tadalafil OaD can help patients maintain PLNES. VED combined with tadalafil OaD can improve the rate of successful penetration (SEP-Question 2) after 12 months. There were no significant differences in the return to target EF after 12 months among the groups. No significant correlation was noted between the variables and return to target EF (IIEF ≥ 17), and between the variables and effective shortening of the patient's penis (shortening ≥ 1 cm) after 12 months of intervention.

BACKGROUND AND PURPOSE: Both genetic factors and smoking are associated with ischemic stroke (IS) risk. However, little is known about the potential interaction of these factors. We aimed to assess whether smoking and a positive family history interact to increase the risk of IS. METHODS: The nationwide prospective study recruited 210,000 men and 300,000 women in 2004 to 2008 at ages 30 to 79 years. During 9.7 years of follow-up, we documented 16,923 and 20,656 incident IS cases in men and women without major chronic diseases at baseline, respectively. Multivariable Cox regression models were used to examine associations between family history and IS. Likelihood ratio tests were used to test the smoking-family history interactions on IS. RESULTS: About 67.8% (n=135,168) of men ever smoked regularly compared with 2.7% (n=7,775) of women. Among men, a significant interaction between family history and smoking on IS was observed (P for interaction=0.03), with more pronounced association between family history and IS among ever-regular smokers (hazard ratio [HR], 1.21; 95% confidence interval [CI], 1.16 to 1.27) than among never-smokers (HR, 1.11; 95% CI, 1.01 to 1.23). The association between family history and IS among ex-smokers after more than 10 years of cessation (HR, 1.01; 95% CI, 0.85 to 1.20) appeared similar to that among never-smokers. Among women, a similar but not significant interaction between family history and smoking on IS was observed. Ever-regular smokers who had a family history of stroke had the highest risk of IS. CONCLUSIONS: Among Chinese men, the association of family history with IS was accentuated by smoking, and such accentuation tended to be lowered by cessation.

BACKGROUND: Hyaluronic acid is an important component of extracellular matrix, has good biocompatibility, unique rheological properties and a variety of physiological functions. Therefore, it has wide application prospect in the tissue engineering. OBJECTIVE: To review the latest research progress in hyaluronic acid scaffold materials in different directions of tissue engineering. METHODS: Using the keywords of "hyaluronic acid, tissue engineering, regeneration, scaffold" in English and Chinese, we retrieved relevant articles published from January 2013 to September 2016 in the databases of PubMed, ScienceDirect and CNKI. RESULTS AND CONCLUSION: The application of hyaluronic acid tissue engineering scaffold materials mainly focuses on the regeneration of bone, cartilage, cardiovascular and nerve. The researchers optimize the composition, ratio of different materials, and modification or cross-linking methods to obtain the ideal scaffold materials to match the mechanical properties and physiological activity of the target tissue. However, there are not enough data on the influence of the molecular weight of hyaluronic acid and the original source of other raw materials on the scaffold properties. Further investigations are needed on the clinical transformation of hyaluronic acid tissue engineering products.

We identified the Beijing family strains of multiple drug-resistant tuberculosis and find out the distribution of second-line injectable drugs resistance-associated nucleotide alteration among the MDR strains in Ningbo.The 106 MDR isolates were selected from the first drug resistant survey in Ningbo during 2014 and 2016.The conventional drug susceptibility testing was used to detect the drug-resistant profiles against 3 second-line injectable drugs (kanamycin,amikacin,capreomycin).The RD105 deletion-targeted multiplex PCR method was used to distinguish the genotype among 106 MDR strains.The gene mutations of second-line injectable drugs resistance-associated among MDR-TB strains were detected by direct DNA sequencing.Results showed that out of the 106 MDR isolates,83(78.3％,83/106) belonged to Beijing genotype,while the other 23(21.7％,23/106) were non-Beijing genotype.There were 10 strains with second-line injectable drugs resistance in 83 Beijing genotype MDR strains and there were no strains with second-line injectable drugs resistance in 23 non-Beijing genotype MDR strains.The Beijing MDR strains had significantly higher proportions of second-line injectable drugs resistance than non-Beijing strains.There were 4 with mutations in 10 MDR-TB with second-line injectable drugs resistance and there were 24 with mutations in 96 MDR-TB without second-line injectable drugs resistance (x2=1.048,P＞0.05).Beijing genotype MDR strains revealed a significant association with second-line injectable drugs resistance.The mechanism of second-line injectable drugs resistance in MDR-TB is mainly in no connection with the mutation of the genes.

The isotopic ratios of strontium isotope (Sr) and light elements (C/H/O/N) in Dendrobium officinale from different producing areas (Shaoguan, Guangdong; Yulin, Guangxi; Shibing, Guizhou; Wenshan, Yunnan and Zhejiang province) were determined with thermal ionization mass spectrometry (TI-MS) and isotope ratio mass spectrometry (IRMS)．The differences of the stable isotope ratios in D. officinale were obtained by the variance analysis and the correlation analysis, and pattern recognition techniques with principal component analysis (PCA) was used to classify the geographical origins of D. officinale from different producing areas．The isotopic ratios of strontium isotope can be used to identified D. officinale in Zhejiang province, and the isotopic ratios of light elements showed the difference followed with the different producing areas. For δD and δ¹⁸ O in samples, maybe influenced by the environment effect. A positive correlation was found between δD and δ ¹⁸O.The principal component analysis was used to discern the samples of D. officinale from different producing areas based on detection technology of stable isotope ratios.These results revealed that it was possible and feasible to classify the geographical origin of D. officinale by the method of determination of isotopes,and provided a new method to identificate origin information of Chinese medicinal materials.

This study aimed to assess the relationship of OAS2 rs739901 5'-flanking C/A polymorphisms with the susceptibility to Enterovirus-71 (EV71) infection.We investigated 294 hand-foot-mouth disease (HFMD) Chinese children with EV71 infection (165 mild cases and 129 encephalitis cases).The improved multiplex ligation detection reaction (iMLDR) technique was used to test the genotypes.In EV71-infected patients,the CA genotype distribution (P=0.007),A allele frequency (OR 1.32,95％ CI 1.0-1.7,P=0.034)and CA+AA carriage frequency (P=0.003) of OAS2 rs739901 5'-flanking were obviously elevated as compared with controls,but there were no statistically significant differences between mild cases and encephalitis cases.In EV71-infected patients,the counts of white blood cells (P=0.034) and blood glucose concentrations (P=0.042) were raised in A carriers (CA+AA).Among different genotypes of encephalitis cases,the contents of cerebrospinal fluid (CSF) showed no significant differences.IFN-γ levels in EV71-infected patients were higher than those in controls (mild group vs.control group,P＜0.01;encephalitis group vs.control group,P＜0.001).In encephalitis cases,IFN-γ levels were reduced (P＜0.05) in A carriers compared to CC genotype,however,there were no significant differences between genotypes CA and AA (P=0.226).These findings suggest that OAS2 rs739901 5'-flanking C/A genetic polymorphisms involve the susceptibility to EV71 infection,and A allele might be a risk factor of the susceptibility to EV-71 infection.

A number of studies have indicated that disorders of consciousness result from multifocal injuries as well as from the impaired functional and anatomical connectivity between various anterior forebrain regions. However, the specific causal mechanism linking these regions remains unclear. In this study, we used spectral dynamic causal modeling to assess how the effective connections (ECs) between various regions differ between individuals. Next, we used connectome-based predictive modeling to evaluate the performance of the ECs in predicting the clinical scores of DOC patients. We found increased ECs from the striatum to the globus pallidus as well as from the globus pallidus to the posterior cingulate cortex, and decreased ECs from the globus pallidus to the thalamus and from the medial prefrontal cortex to the striatum in DOC patients as compared to healthy controls. Prediction of the patients' outcome was effective using the negative ECs as features. In summary, the present study highlights a key role of the thalamo-basal ganglia-cortical loop in DOCs and supports the anterior forebrain mesocircuit hypothesis. Furthermore, EC could be potentially used to assess the consciousness level.
