This study was aimed to carry out the research by statistics to analyze the influence of specific clinical function of Dioscorea opposita Thunb. from the viewpoint of prescription in order to summarize its rules. Formula containing D. opposita Thunb. in the classic book of the Formula Dictionary of Traditional Chinese Medicine were recorded. The prescription type of D. opposita Thunb. was taken as the mainline. Excellwas used in the chart analy-sis. The results showed that for the function of reinforcing spleen-stomach, the effect of powder was increased, but the effect of pill was reduced. For the function of reinforcing lung and generating essence, the effect of decoction was significantly increased, but the effect of pill was significantly reduced. For the function of reinforcing kidney-yin, the effect of pill was significantly increased, but the effect of decoction was reduced. For the function of strengthening the kidney and restraining yin, the effect of powder was reduced. It was concluded that preparation had a strong in-fluence on the clinical function of D. opposita Thunb., which provided references for both clinical practice and health cultivation.

This article was aimed to study on clinical application of Shanyao (Dioscorea opposita Thunb.) in each historical period, which can offer some suggestions for clinical doctors to use Shanyao correctly. A total of 668 pieces of formulae containing Shanyao were recorded from the classic format Dictionary of Traditional Chinese Medicine Formula. And then, statistic analysis was made on the emerging frequency according to its effect. The results showed that different effects of Shanyao started to be widely applied from the Song dynasty. It was most widely applied in the Ming and Qing dynasty. Nowadays, the difference between using Shanyao has been gradually decreased. During the whole historical period, clinical functions of Shanyao are mainly reinforcing the spleen and the stomach, tonifying the kidney and strengthening yin. However, clinical functions of reinforcing the kidney and restraining yin, tonifying the lung and promoting fluid are used secondly. It was concluded that the research analyzed clinical application of Shanyao in each historical period, which can offer scientific basis for clinical practice and health maintenance with the using of Shanyao.

Objective To investigate the levels of serum tHcy and Lp(a)and their association with insulin resistance in patients with type 2 diabetes and CHD. Methods T2DM patients were divided into two groups with CHD and without CHD in addition to normal control.The fasting serum levels of tHcy,Lp(a),FPG and FIns were detected, ISI were calculated，and the correlations among them were analyzed. Results The serum levels of tHcy,Lp(a),FIns,FPG of T2DM plus CHD were significantly higher than those of T2DM without CHD and controls(P<0.01~0.05).ISI was significantly lower in T2DM cases with CHD than those of T2DM cases without CHD and controls(P<0.01). ISI was negatively correlated with tHcy and Lp(a)in T2DM plus CHD group(P<0.05)but not correlated with those in T2DM case without CHD group(P>0.05). Conclusions Detections of the serum levels of tHcy and Lp(a)of T2DM play significant roles in knowing patient condition,guiding clinical treatment and earlier preventing and treating vascular complication of diabetes.

Objective To explore the etiology of abdominia incision hernia and treatments of giant incisional hernia of abdominal wall. Methods 14 cases with AGIH treated in our hospital from Oct 2003 to May 2008 were analyzed retrospectively. Results The etiology of abdominia incision hernia were very important,and abdominal longitudinal incision was performed, 10 cases ＞ 67y among 14 cases with incision hernia were 71.42%. Infection of incision and essential conditions( diabetes, chronic cough ,hypoalbum inemia)were also easily induced of incisional hernia. All of them chose the marlex patch. The cases were all cured and no serious postoperative complications. None of cases recurred during a follow up of 3 to 56 months. Conclusion The etiology of AGIH related with longitudinal incision,old ( ＞ 60y)and essential conditions. AGIH were repained with polypropylene mesh. Essential conditions should be treated before operation and abdominal wall should be trained comfortablely. Repairing abdominal incision hernial with artifical patch was a safe and simple operation with minimal postoperation pain.

Objective To investigate influence and significance of preoperative transcatheter arterial chemoembolization (TACE) on disease-free survival rates and overall suvival rates in patients with respectable large hepatocellular carcinoma(HCC). Methods One hundred and eight patients with respectable large primary liver cancers were prospectively randomized into two groups: preoperative TACE group(n=52) and one-stage operation group(n=56). We compared between two groups according to daughter nodules and tumor thrombus. Results There were no significant differences in the incidence of disease-free survival rates and overall suvival rates in the two groups. Conclusion Preoperative TACE for resectable large HCC should be used on bases of strict selection because it does not decrease the recrudescence rates and results in delayed surgery in some cases.

Transposons are the mobile and autonomic replication DNA fragments in genomes. With more understanding of the structure and function of transposons, numerous transposons have been developed to the genetics tool for gene function analysis, gene transformation and gene therapy. The low transpositional activity of the natural transposons is the main obstacles to the utilization of transposons. Recently, with the progress in bioinformatics and protein engineering methods, researchers have reconstructed and optimized natural transposases to create hyperactive transposases that catalyze the transposition with high efficiency. The resulted hyperactive transposons have been applied to gene-modification and gene-tagging. Meanwhile, transposase chimeras were created by protein fusion technology. The insertion characteristic of transposons were artificially regulated which could be utilized in gene therapy.

It is widely accepted that diabetes is intimately linked to diet. The latest researches showed that diet-microbiota interactions acted as moderators of human diabetes. Gluten-free diet and hydrolyzed protein decreased the incidence of type 1 diabetes mellitus (T1DM)by the mechanism of changes in gut microbiota and immune micro-environment. Consuming more dairy products decreased the incidence of type 2 diabetes mellitus (T2DM). High fat diet can induce insulin resistance (IR),thus increasing the incidence of T2DM. Parental dietary affected on offspring diabetes by the epigenetic mechanism. Low carbohydrate diet,dietary fiber and legumes were effective to the treatment of diabetes. Prediction of postprandial glucose level and treatment based on gut microbiota contributed to control the glucose of diabetic patients. An in-depth understanding of these mechanisms provides new ideas for the individualized and precise treatment of diabetes.

The afferent connections of the preoptic region in the rat were studied with retrograde horseradish peroxidase (HRP) method.The mico-injection syringe needle or microelectrophoretic pipette was inserted vertically into the brain. In some cases, the injection was made with the needle inclined and directed contralaterally or in inclined direction through the cerebellum.The results were as follows:Following HRP injection into the medial preoptic area, labeled neurons were found in periventricular hypothalamic gray, paraventricular nucleus, anterior hypothalamic nucleus, supraoptic nucleus, ventromedial hypothalamic nucleus, posterior hypothalamic nucleus and locus coeruleus in all cases. In some cases, labeled cells were also observed within bed nucleus of stria terminalis, dorsal raphe nucleus. In addition, in a few cases, a small number of labeled cells could be found in lateral septal nucleus, medial septal nucleus, periaqueductal gray matter and interpeduncular nucleus.After injection into the region between the medial and lateral preoptic area, besides the above mentioned labeled nuclei, there were still a number of labeled cells found in paratenial nucleus, nucleus reuniens and lateral hypothalamic nucleus, in some cases also found in the supramammillar nucleus, and in one case even in the cortical and medial amygdalar nuclei.Following the injection of HRP into the anterior hypothalamic nucleus, retrograde labeling of neurons was observed within the lateral septal nucleus, preoptic periventricular nucleus, medial preoptic nucleus, supraoptic nucleus, periventricular hypothalamic nucleus, paraventricular nucleus, ventromedial hypothalamic nucleus, periaqueductal gray matter and locus coeruleus in all cases. Among them, supraoptic and paraventricular nuclei were labeled bilaterally in some cases.
