ObjectiveTo investigate the characteristics of Kienbock's disease in patients older than 60 years of age.MethodsGender, age at onset, affected side, dominant hand, occupation, and clinical results in 7 wrist of 7 elderly patients with Kienbock's disease were investigated.ResultsKienbock's disease in elderly patients commonly was observed in the dominant hand of manual works and was found more often in women than in men. The age at onset was from 60 to 70. Although radiographic examination revealed development of carpal collapse in all patients.ConclusionThe etiologic factors different from conventional ones might have played a role in aged patients with Kienbock's disease, surgical and rehabilitation treatments are good or excellent.

Linear solvation energy relationships are of a great value in investigating quantitative structure-retention relationship and quantitative structure-activity relationship, and predicting chromatographic retention indices of drugs. Several quantitative relationships in different in vitro biomembrane-mimetic models between retention factors and molecular descriptors have been established successfully and used to clarify drug-membrane interaction mechanisms. Quantitative structure-activity relationships also have been established to predict drug intestinal absorption, permeation of skin and blood-brain barrier. This review focused on the significance and widely application of linear solvation energy relationships in quantitative assessment for mechanisms of partitioning and absorption of drugs. The discrepancy and limits of linear solvation energy relationships were also discussed, which gives us a better insight into investigation of partitioning and absorption of drugs.

Objective To determine the long term outcomes of laryngomalacia infants with anomalies and to determine the clinical practice guideline for these infants.Methods The charts of infants with moderate to severe laryngomalacia,who were admitted to our hospital between January 2013 and December 2015,were retrospectively reviewed.These infants were divided into two groups,anomaly(A) group(n=37) and non-anomaly (NA) group(n=19).Results Fifty-six cases were enrolled.Infants in A group were older at symptom relief than those in NA group[(10.00±3.56) months vs.(7.89±3.03) months,P<0.05],and the weight percentiles of infants in A group were lower at 3,6 and 12 months than those in NA group(P<0.05).There was no statistically significant difference between the two groups on the weights percentiles in infants at 24 months after diagnosis.Five of 37 cases in A group and 3 of 19 cases in NA group had supraglottoplasty.One infant in A group had tracheotomy.Conclusion Both breathing difficulty and development retardations of infants with moderate or severe laryngomalacia could gradually improved with age.There is not enough evidence to support the aggressive supraglottoplasty for infants with anomalies and laryngomalacia.

Objective To evaluate the effect of Naogongfude (NGFD, a traditional Chinese medicine orally administrated) on learning and memory and the expressions of synaptophysin (SY) and Tau-protein in cerebral cortex and hippocampus in aged rats and to explore the possible mechanism. Methods Rats were divided into normal and neural disturbance groups according to the outcomes of active avoidance reaction (AAR) test, and then each group was randomly divided into control and NGFD-treated experimental groups. Animals were orally fed with NGFD for 2 months (5 ml/d) in experimental group or routinely fed in control and taken AAR and passive avoidance reaction (PAR) tests. After the rats were sacrificed, the synaptosome count, the expression of SY and Tau-protein, and the neuron apoptosis in cerebrum were examined. Results The rats after 2-month NGFD administration had an increased AAR acquisition, obviously delayed AAR extinction and prolonged step through latency (STL) of PAR. The number of synaptosomes was raised and the immunoreactive intensity of synaptophysin was increased remarkedly, while Tau-protein immunoreactivity and apoptotic cells were decreased in cerebrum. Conclusion NGFD does have the effect of improving brain function and putting off the aging of rat brain according to the results of behavior study and morphological observation.

The role of pulchinenoside (PULC) in the regulation of MeCP2 expression was investigated in RA model rats. Adjuvant arthritis rats were used as RA model rats, and fibroblast-like synoviocytes (FLS) from the RA model rats were cultured. The effect of 100 mg x kg(-1) PULC gavage treatment on the MeCP2 expression and the effect of MeCP2 siRNA on the expression of SFRP2 and β-catenin were detected by real time qPCR and Western blotting. The role of PULC in the FLS proliferation was detected by MTT. The results showed that the MeCP2 expression was down-regulated, the SFRP2 expression was up-regulated and the FLS proliferation was inhibited in FLS after therapy. MeCP2 siRNA significantly inhibited the MeCP2 expression, up-regulated the SFRP2 expression and inhibited the β-catenin expression in FLS from RA model rats. PULC may increase the SFRP2 expression, inhibit the Wnt signaling and inhibit the FLS proliferation in FLS from the RA model rats by inhibiting the MeCP2 expression.

To study the effect of pulchinenoside (PULC) on the Frizzled (FZD) expression of adjuvant arthritis ( AA) rats. AA rats were prepared through the toe injection with complete Freund's adjuvant to culture fibroblast-like synoviocytes (FLS). The effect of the oral administration with PULC on the FZD8 expression was detected by the real time qPCR. The effect of FZD8 knockout on the expressions of IL-1, IL-6, IL-8 were detected by MTT and ELISA. The role of miR-375 in the abnomal expression of FZD8 was detected by the real time qPCR. The results showed signfiicant decrease in the FZD8 expression among AA rats, FLS proliferation ater FZD8 knockout and IL-1, IL-6, IL-8 expressions and notable increase in miR-375 expression after the oral administration with PULC. The up-regulated miR-375 expression can inhibit the FZD8 expression. PULC may inhibit the FZD8 expression by up-regulating the miR-375 expression.
