Objective To study aminopeptidase N/CD13 expression in hepatocellular carcinoma and its relationship with clinical data and proguosis in patients with hepatocellular carcinoma.Methods The immunohistochemical SP method was used to detect the CD13 monoclonal antibody in 40 cases of hepatocellular carcinoma,10 cases of corresponding para-carcinoma and 10 cases of cavernous hemangioma.Results Forty cases ( 100% ) hepatocellular carcinoma tissues were seen varying degrees of CD13 expression,3 (30%) corresponding para-carcinoma tissues were weakly positive,and 10 cases of cavernous hemangioma with no expression.The expression rate of CD13 was not significantly correlated with the patient gender,age,serum AFP value,HbsAg,differentiation,CHILD grade and TNM stage (P>0.05).But the expression of CD13 was closely related with the patient serum AFP value,HbsAg,differentiation ( P < 0.05 ).By the survival function graph we could find the expression rate was negativly correlated with survival in patients,but the expression was not significantly correlated with tumor relapse.Conclusion CD13 can be used as the surface marker of liver cancer stem cells,and it is expected to become an effective indicator of prognosis in patients with hepatocellular carcinoma.

Depression is one of the diseases with the highest disability rate in the world. A large number of studies have shown that the intake of unsaturated fatty acids can deal with depression while chronic overconsumption of saturated fatty acids is a risk factor for depression. It was suggested that the mechanism of saturated fatty acids inducing depression is related to the following four aspects: regulating the function which links to depression in whole brain and specific brain regions, including the hippocampus, the hypothalamic-pituitary-adrenal axis, the striatum, and the prefrontal cortex; stimulating the secretion of inflammatory factors; affecting the balance and function of metabolic regulatory hormones, including leptin, adiponectin, glucocorticoid, and insulin; inducing the disturbance of intestinal flora. This article reviews the relationship between dietary fatty acids and depression, and the possible mechanisms by which saturated fatty acids induce depression from the four aspects mentioned above.

Depression is a devastating mental disorder and major depressive disorder (MDD) that afflicts 16% of the global population at some point in their lives. Currently available classical antide-pressants (SSRIs, SNRIs, TCAs and MOIs), require a minimum of 2–4 weeks of continuous treat-ment to elicit therapeutic relief in depressed patients and are associated with high rates of non-respon-siveness, and limited duration of efficacy. Therefore, faster-acting antidepressant therapies are need-ed,particularly for patients at risk for suicide for current therapies for depression.Although the molecu-lar mechanisms underlying the pathogenesis of depression are still largely unclear, previous studies have suggested that modulators of mammalian target of rapamycin complex 1 (mTORC1) signaling may have beneficial neuroprotective and antidepressant effects. Here, we review recent advances in understanding mTORC1 signaling in depression and potential therapeutic strategies resulting from modulation of the mTORC1 signaling network. We also highlight recent studies considered to support mTORC1 signaling modulation as a rapid-acting antidepressant therapy (e.g. ketamine, scopolamine, GLYX-13, (2R,6R)-HNK, Ro-256891 etc.) and discuss future research directions. Studies on prospec-tive next-generation rapid-acting antidepressant therapies should focus on developing more selective glutamate receptors(e.g.α-amino-3-hydroxy-5-methyl-4-isoxazole propionic acid receptors(AMPARs) agonists or activators)that activate the mTORC1 signaling pathway free of ketamine's adverse effects.

Objective To investigate the effect of low frequency electric deep brain stimulation on amygdale kindling in rats.Methods The amygdale kinkling model of rats was established by operation on the brain.The effects of low frequency deep brain electric stimulation used alone or in combination with anti-epilepsy drugs were ob- served in terms of severity of seizure attack reflected by Racine's scale and afterdischarge duration recorded in electro- encephalogram.Results Fifteen minutes of low frequency electric stimulation at 1 Hz and 100 to 350?A effective- ly inhibited amygdale kindling as demonstrated by a significant decrease of afterdischarge duration,and decreased the severity of seizure attack (P

OBJECTIVETo observe differences of therapeutic effects among acupuncture bloodletting, penicillin and acupuncture bloodletting combined with penicillin for children acute tonsillitis and providea better treatment method in cli nic.
METHODSSeventy-five mild cases were selected into section of mild symptoms while seventy-five severe cases were selected into section of severe symptoms. Cases in the two sections then were divided into, an acupuncture bloodletting group, a penicillin group and a comprehensive group by random digital table method separately, 25 cases in each one. Qu-chi (LI 11), Hegu (LI 4), Dazhui (GV 14), Shaoshang (LU 11) and Erjian (EX 11) were selected in the acupuncture bloodletting group, intravenous injection of penicillin sodium was applied in the penicillin group and acupuncture bloodletting combined with penicillin was applied in the comprehensive group. Efficacy assessment was conducted after 3 days in the section of mild symptoms and after 5 days in the section of severe symptoms.
RESULTSFor the section of mild symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group and 92.0% (23/25) in the acupuncture bloodletting group, which were both superior to 68. 0% (17/25) in the penicillin group (P<0.05), but no statistical significance was seen between the comprehensive group and acupuncture bloodletting group (P>0.05). For the section of severe symptoms, the total effective rate was 96.0% (24/25) in the comprehensive group, which was obviously superior to 60.0% (15/25) in the acupuncture bloodletting group (P<0.01) and 68.0% (17/25) in the penicillin group (P<0. 05), and no statistical significance was seen between the acupuncture bloodletting group and penicillin group (P>0.05).
CONCLUSIONThe efficacy of acupuncture bloodletting combined with penicillin is little different from that of acupuncture bloodletting for treatment of children acute tonsillitis with mild accompanied symptoms, which were both superior to intravenous injection of penicillin sodium. For severe accompanied symptoms, the efficacy of acupuncture bloodletting combined with penicillin is obviously superior to acupuncture bloodletting and penicillin.

OBJECTIVE:To extract the feature of Achyranthes bidentata and Cyathula officinalis,and to establish image recog-nition method. METHODS:The microscopic image stitching of A. bidentata and C. officinalis was implemented by MATLAB. The color,invariant moment,stripes and the features of vascular bundle in cross section were extracted. The data was organized into da-ta matrix,and then data matrix was standardized by Zscore function;principal components were analyzed through Princomp func-tion. BP nerve network recognition mode was adopted. RESULTS:The microstructures in the micro images of the samples were kept integrated. The measured data of 27 characteristics were acquired in each group of sample. Through principal component analy-sis,the parameters of 11 main components were selected to establish BP never network. The average recognition rate of BP nerve network was 100% between 2 medicinal material relatives (n=50). CONCLUSIONS:The method can be used for micro-image auto Stitching of Chinese medicinal materials and image recognition of A. bidentata and C. officinalis.
