Objective To study water-soluble constituents of Dioscorea zingiberensis in order to seek active components. Methods Various chromatographic techniques were used to isolate the constituents. Structures of compounds were elucidated by spectroscopic analyses of 1H-NMR, 13C-NMR, 135DEPT, HMQC, HMBC, and TOCSY. Results One new steroidal saponin was isolated and identified as 26-O-(?-D-glucopyranosyl)-(25R)-furost-5-en-3?, 26-diol-22-OMe-3-O-｛?-L-rhamnopyranosyl-(1→4)-[?-D-glucopyranosl-(1→3)-?-D-glucopyranosl-(1→2)]-?-D-glucopyranoside｝. Conclusion The compound is a novel compound named as zingierenin E. The other two compounds are reported for the first time from D. zingiberensis.

Serum Cholyglycine (CG)is a main component of human bile acid,one of the conjuga-ted bile acids formed by the combination of bile acid and glycine is synthesized in the liver cells.Glycochol-ic acid (CG)as a clinical indicator for detecting hepatobiliary disorders,and the traditional index of liver
function test compared has greater advantages,its detection for intrahepatic cholestasis,liver disease and biliary system diseases diagnosis,treatment and prognosis analysis of pregnancy to provide an important ba-sis.

RNA interference (RNAi) is a powerful endogenous process initiated by short double stranded RNAs, which results in sequence-specific posttranscriptional gene silencing. Because any protein that causes or contributes to a disease is susceptible to RNAi, the RNAi has high potential for therapeutic treatments. In a clinical setting, however, there are many obstacles to targeted delivery of small interfering RNA (siRNA) in vivo, specificity and stability of the RNAi reagents. In this review, we focus on recent progress in the development of efficient siRNA delivery vehicles to help the application of siRNA to in vivo therapy.

Objective To investigate the accuracy of transthoracic echocardiography (TTE) for diagnosing left cardiac valve calcification in elderly patients.Methods In this retrospective study,410 elderly patients died in Beijing Hospital from 1982 to 2015 were collected.They all had full pathological cardiac valve examination data in the autopsy examination and full mortem TTE data.They were classified into three groups according to the year of death:group 1982-1995,group 1996-2005 and group 2006-2015,as well as into three groups according to the age of death:group 60-75,group76-90 and group 91-106.Results The sensitivity,specificity,diagnostic coincidence rate,positive likelihood ratio (PLR),negative likelihood ratio (NLR),positive predictive value (PPV) and negative predictive value(NPV) of TTE versus autopsy pathological findings as golden standard for diagnosing left cardiac valve calcification were 88.6％,28.2％,43.7％,1.234,0.405,0.298 and 0.878.Compared with group 1982-1995,the group 1996-2005 and group 2006-2015 showed the sensitivity and PPV of TTE versus golden standard autopsy findings for diagnosing left cardiac valve calcification in the elderly were increased while the specificity,PLR,NLR and NPV were decreased.Compared with group 60-75,the group 76-90 and group 91-106 showed that the sensitivity and PPV of TTE versus golden standard autopsy findings for diagnosing left cardiac valve calcification were increased,while the specificity and diagnostic coincidence rate were decreased.The sensitivity,specificity,diagnostic coincidence rate,PLR,NLR,PPV,NPV of TTE versus golden standard autopsy findings for the diagnosis of aortic valve calcification and mitral valve calcification in the elderly were 88.2％ and 44.0％,30.8％ and 75.3％,42.7％ and 71.5％,1.275 and 1.780,0.382 and 0.744,0.250 and 0.198,0.909 and 0.906,respectively.Conclusions TTE provides high sensitivity for diagnosing left cardiac valve calcification in the elderly,especially for diagnosing the aortic valve calcification,but the specificity is not satisfactory.

Objective: To compare the efficacy of goal-activity-motor environment (GAME) therapy and neurodevelopmental therapy (NDT) in the early intervention of high-risk infants with cerebral palsy (IHRCP), and to provide scientific evidence-based medical basis for early intervention of IHRCP. Methods: A total of 62 cases of IHRCP were enrolled in the Children′s Neurological Rehabilitation Center of the First Affiliated Hospital of Anhui Medi-cal University from June 2017 to December 2018.They were divided into GAME group (32 cases) and NDT group (30 cases) according to the admission order.Gross Motor Function Scale (GMFM), Fine Motor Function Measure (FMFM) and Gesell Development Scale (GDS) were used for detection and comparison.The differences among the gross motor, the fine motor score and the developmental quotient (DQ) between two groups before treatment, 9 months after treatment and 12 months after treatment, and the normalization rate and the incidence of cerebral palsy between the two groups at 12 months of age were compared. Results: (1) Motor function was as follows: at 9 months[GAME: (32.63±15.83) scores, (30.03±15.88) scores], [NDT: (33.37±15.61) scores, (29.67±12.54) scores] and at 12 months[GAME: (40.56±15.79) scores, (36.31±14.98) scores], [NDT: (40.47±15.50) scores, (36.73±14.58) scores] after treatment, and GMFM and FMFM scores in GAME and NDT groups were significantly higher than those before treatment[GAME: (27.56±14.24) scores, (21.75±11.35) scores], [NDT: (26.93±14.96) scores, (21.30±10.67) scores], and the differences were significant (all P<0.01), but there was no significant difference between the 2 groups (all P> 0.05). (2) DQ had no significant difference in DQ between GAME group(63.59±10.83) and NDT group (61.59±7.96) before treatment (P>0.05). The total DQ at 9 months, 12 months, the total DQ of GAME group (73.67±12.00, 81.59±13.03) was significantly higher than that of NDT group (66.05±9.54, 75.17±1.92) (all P<0.05). Among them, the improvement of GAME in speech (79.84±16.56, 83.19±17.05) at 9 months and 12 months, and adaptive ability(78.63±16.37, 85.78±13.60) were significantly higher than that of NDT group(71.63±13.36, 72.53±12.77), (68.20±14.97, 77.43±12.10), and the differences were significant (all P<0.05). (3) Prognosis was as follows: at 12 months after treatment, 25 cases in GAME group and 23 cases in NDT group developed into normal children, there was no significant difference in the normalization rate between the 2 groups (P>0.05); the incidence of cerebral palsy was present in 6 cases in GAME group and 5 cases in NDT group, and there was no significant difference between the 2 groups (P>0.05). Conclusions GAME therapy and NDT had significant effects on both gross and fine exercise of IHRCP, and the efficacy of the two methods is similar.Both GAME therapy and NDT can equally promote IHRCP development into normal infants and reduce the incidence of cerebral palsy.
