Objective To analyze the curative effect of minimally invasive incision combined with plate fixation for calcaneal fractures.Methods Retrospectively analyzed the clinical data of 30 cases(30 feet) of calcaneal fractures who were treated with minimal incision(sinus tarsi approach combined with posterior lateral incision) from August 2014 to August 2015.Minimally invasive incision combined with plate fixation were performed for the treatment.X-rays were taken in the regular follow-up,B(o)hler and Gissane angle as well as the complications were measured.The final curative effect was comprehensively assessed according to the ankle hind foot score of American Aryhopaedic Foot and Ankle Society(AOFAS).Results All cases were followed up for an average of 14.5 months (from 12 to 16 months), and all fractures healed with no complication such as incision infection or poor healing.The average B(o)hler angle was improved from preoperative(13.42°±4.2°) to (29.3°±3.8°) at the last follow-up with a significant difference(t=-20.424,P=0.000),and the average Gissane angle was significantly improved from preoperative(97.8°±9.7°) to (123.6°±6.5°) at the last follow-up (t=-17.5,P=0.000).The outcomes were evaluated with AOFAS,resulting in an excellent and good rate of 83.3%.Conclusion Treatment of calcaneal fractures with minimal incision has the advantages of less trauma,lower incision complication rate,stronger reduction and fixation,which can achieve satisfactory outcomes.

OBJECTIVETo investigate the levels of secretions from the prostate and seminal vesicles and their association with the expressions of aquaporins (AQP) in the prostatic tissue and seminal vesicles of castrated rats.

METHODSWe randomly divided 18 eight-week-old male SD rats into a control, a castration, and a testosterone (T) replacement group. Four weeks after surgical castration, we detected the plasma T level and measured the volumes of the secretions and the expressions of AQPs 3, 7, and 10 - 12 in the prostate and seminal vesicles of the rats.

RESULTSThe plasma T level was significantly lower in the castrated models ([30. 98 ± 28. 84] ng/dl) than in the rats of the control ([700.78 ± 123.8] ng/dl) and T replacement groups ([688.08 ± 132. 47] ng/dl) (P <0. 05). The castration group, in comparison with the control and T replacement groups, showed remarkably reduced ratios of prostatic secretion volume / prostate weight ([11.1 ± 0.30] vs [2.32 ± 0.61] and [2.13 ± 0.56] %, P <0. 05) and seminal vesicle secretion volume / seminal vesicle weight ( [4. 78 ± 1. 97 ] vs [57. 36 ± 11. 86] and [55. 74 ± 7. 21] %, P < 0. 05). Immunohistochemistry revealed the expressions of AQPs 3 and 7 in the epithelial envelop and cytoplasm and that of AQP 11 the in endothelial envelop and cytoplasm of the prostate and seminal vesicles. Western blot exhibited significantly lower expressions of AQPs 3, 7, and 10 - 12 in the prostate and seminal vesicles of the castrated rats than in the animals of the control and T replacement groups (P <0. 05).

CONCLUSIONSignificant decreases of the secretions from the prostate and seminal vesicles may be related to the reduced expressions of AQPs 3, 7, and 10 - 12 in the prostatic tissue and seminal vesicles in castrated rats.

The present study aims to predict the action targets of antidepressant active ingredients of Xiaoyaosan to understand the "multi-components, multi-targets and multi-pathways" mechanism. Using network pharmacology, the reported antidepressant active ingredients in Xiaoyaosan (saikosaponin A, saikosaponin C, saikosaponin D, ferulic acid, Z-ligustilide, atractylenolide I, atractylenolide II, atractylenolide III, paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid and pachymic acid), were used to predict the targets of main active ingredients of Xiaoyaosan according to reversed pharmacophore matching method. The prediction was made via screening of the antidepressive drug targets approved by FDA in the DrugBank database and annotating the information of targets with the aid of MAS 3.0 biological molecular function software. The Cytoscape software was used to construct the Xiaoyaosan ingredients-targets-pathways network. The network analysis indicates that the active ingredients in Xiaoyaosan involve 25 targets in the energy metabolism-immune-signal transmutation relevant biological processes. The antidepressant effect of Xiaoyaosan reflects the features of traditional Chinese medicine in multi-components, multi-targets and multi-pathways. This research provides a scientific basis for elucidation of the antidepressant pharmacological mechanism of Xiaoyaosan.

The purpose of this study is to explore depression metabolic markers in rat hippocampus and to investigate the anti-depressant effect of genipin and its mechanisms using nuclear magnetic resonance (NMR) metabonomics. Chronic unpredictable mild stress (CUMS) procedure was conducted to establish the depressive rat model. At the beginning of the third week, genipin low dose (25 mg x kg(-1)), middle dose (50 mg x kg(-1)), high dose (100 mg x kg(-1)), and venlafaxine (50 mg x kg(-1)) were given to the CUMS rats separately once daily for two weeks except control and model groups. Rat hippocampus was analyzed by 1H NMR based metabonomics after drug administration for 2 weeks. Significant differences in the metabolic profile of rat hippocampus of the CUMS treated group and the control group were observed with metabolic effects of CUMS including decreasing in glycine and N-acetylaspartate, increasing in inositol, glutamate, lactate, glutamine, taurine and alanine. Genipin showed ideal antidepressive effects at a dose of 50 mg x kg(-1) in rats, decrease of inositol, glutamate, lactate, alanine were observed, while glycine and N-acetylaspartate were increased. Important influence has been found on normal nervous system function of these significant changed metabolites, which suggests that the antidepressant effect of genipin may be played by enhancing the activity of neurons in hippocampus, repairing and improving the function of the neuron. The metabonomics approach is an effective tool for the investigation of the anti-depressant effect and pharmacologic mechanisms of genipin.
