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.

Congenital cataract is a common eye disease which leads to children low vision. Surgery is the main treatment. Because of children's preoperative evaluation, operation, postoperative management is more difficult than adult, the outcome of surgery is not so well. Therefore, we review the relevant congenital cataract surgery researches in recent years in order to discuss the problems and further developments in this area.

Objective To observe the effect of Morita therapy on self-esteem level and life satisfaction in schizophrenic patients. Methods 140 schizophrenic patients received Morita therapy, and followed up for 1 year. Self- esteem Scale (SES), Life Satisfaction Index B (LSIB), and Personal and Social Performance scale (PSP) were evaluated. Results The scores of SES and LSIB significantly improved after treatment (P=0.000). 117 cases (83.57%) were in stable condition; 20 cases (14.29%) were in unstable condition with poor medication compliance; only 3 cases (2.14%) needed to be re-hospitalized due to relapse. The 117 cases were followed up for 1 year, and their SES and LSIB scores maintained at the level when discharge, in which 94 cases kept in well social function. Conclusion Morita therapy can improve the self-esteem and life satisfaction of schizophrenic patients, and maintain good social function.

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.

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.

AIM To inVestigate the positiVe transcription elongation factor b(P-TEFb)expressjon and the effect of berberine on diabetic retina of the rat.METHODS Type 2 diabetes mellitus rat models were diabetic control rats(group A)that neither received STZ nor the high-carbohydrate/high-fat diet;16-wk diabetic rats without any drug treatment(group B);diabetic rats treated with berberine at a dose of 75,150 or staining and P-TEFb(cyclin-dependent kinases 9(CDK9)and cyclin T1)protein expression was detected by immunohistochemjstry.RESULTS The retinas of control group were thicker than those of other 6 groups.After thickness but no difference in retinal structure among all groups.Middle-.high-dose berberine and rosiglitazone fenofibrate showed no effect on CDK9 and cyclin T1 expression.CONCLUSION Berberine modulating P-TEFb level in diabetic retina may probably be one of the mechanisms to ameliorate retinopatby induced by STZ and the high-carbohydrate/high-fat diet.

AIM To investigate cyclin dependent kinase 9(Cdk9) and cyclin T1 protein expressions in diabetic rat kidney and the effect of berberine on them. METHODS Type 2 diabetes mellitus (T2DM) rats were induced by injection (ip) with diet for 16 weeks. From week 17 to 32, diabetic rats were given berberine 75, respectively. The kidney tissue structure was observed with hematoxylin/eosin (HE) staining, kidney to body weight ratio was calculated, and Cdk9 and cyclin T1 expressions were examined by immunohistochemistry. RESULTS Compared with control rats, the volume of diabetic model rat glomerulus accreted, some intercapillary cells proliferated and mesangial region expanded, both glomerular basement membrane and renal tubular basement membrane thickened. Treatment with diabetic nephropathy symptom. The diabetic kidney to body weight ratio protein expressions in diabetic kidney to near control level. CONCLUSION Berberine regulates Cdk9 and cyclin T1 protein expressions in diabetic kidney which may partly contribute to ameliorate nephropathy complication induced by STZ and the high-carbohydrate/high-fat diet.
