Objective To study P300 of the first episode depression and mismatch negativity(MMN) changes after antidepressant treatment. Methods Sixty-four patients with first episode depression were evaluated by HAMD 17, and P300 and MMN tests were performed at the baseline and week 12. The cognitive potentials were compared with those of control group(N=36). Results Compared with the control group, depressive patients had longer latency of P300 and MMN,lower amplitude of P300 and MMN before treatment (P

ObjectiveThe aim of this study is to analyze the etiology and status of bone age of children with short stat-ure.MethodsAnthropological and physical examination data were retrospectively collected and studied in 2132 children with short stature in the department of endocrinology between 2009 and 2014. Growth hormone (GH) levels were determined by ar-ginine-clonidine test. Bone age was determined by CHN scoring.ResultsAmong the 2132 patients, 1333 were males and 799 were females. Mean age is 9.03 ± 3.04 years old, mean bone age is 6.81 ± 3.05 years. Of them, 324 cases (15.2%) were diagnosed complete GH deifciency, 780 cases (36.59%) were partial GH deifciency, 27cases (1.27%) were multiple pituitary hormone de-ifciency, 13 cases (1.64%) were hypothyroidism, 893 cases (41.89%) were idiopathic short stature, 19 cases (0.89%) were small for gestational age (SGA), 40 cases (1.88%) were chromosomal disorders, etc. Signiifcant difference in age and bone age was found using t test (P<0.05). Signiifcant differences in Δage were found between etiological categories using ANOVA (P=0.000). Δage was signiifcantly and negatively associated with peak GH using Pearson's correlation.ConclusionsGH deifciency is the most common cause of short stature. Bone age of children with short stature is commonly delayed. Δage was signiifcantly and negatively associated with peak GH. Multiple pituitary hormone deifciency has a signiifcant effect on bone age. The etiology of patients with short stature cannot be determined just by bone age.

OBJECTIVETo study the simple infection and super/co-infection of HAV-HEV, HGV in patients with viral hepatitis.

METHODSUsing EIA method to detect anti-HAV IgM, HBV serum markers, anti-HCV IgM, anti-HDV IgM, anti-HEV IgM, anti-HGV IgM in viral hepatitis patients with different clinical types.

RESULTSSeventy-three percent patients (154/210) had HBV infection markers, twenty-nine percent patients (61/210) had HAV infection marker, eight percent patients (17/210) had HCV, HDV infection markers, ten percent patients (21/210) had HEV infection and seven percent patients (15/210) had HGV infection. Only nine percent patients (20/210) had viral hepatitis serum markers negative. In all clinical types, sixty-one percent patients had only one type hepatitis virus infection, thirty-two percent patients had two types of hepatitis virus super/co-infection, six percent patients had three types of hepatitis virus super/co-infection. Super/co-infection often occurred in patients who had cirrhosis or hepatic failure.

CONCLUSIONHBV and HAV infection is very common in viral hepatitis patients, whereas HCV, HDV, HEV and HGV infection is relatively low; double super/co-infection of HAV-HEV, HGV frequently occurs in severe patients with viral hepatitis.

Cancer, an abnormal cell proliferation resulted from multi-factors,has the highest morbidity and mortality among all the serious diseases. Considerable progress has been made in cancer biology in recent years. Tumor immunology, cancer stem cells (CSCs), autophagy, and epithelial-mesenchymal transition (EMT) have become hot topics of interests in this area. Detailed dissection of these biological processes will provide novel directions, targets, and strategies for the pharmacological evaluation, mechanism elucidation, and new drug development of traditional Chinese medicine.

In order to establish a method by which the recombinant suicide plasmids integrated on the chromosome could be recircled, A simple method of transconjugative cloning was established with the helper plasmids pMT999 or pRK2013 and fusion strains of Shigella flexneri which were obtained by screening with in vivo expression technology. And the cloning efficiency with this method is very high.

OBJECTIVETo evaluate the erectile and ejaculatory function of sacral tumor patients after sacral nerve root resection and investigate the relationship of erectile and ejaculatory dysfunction (EED) with the level of sacral nerve injury.

METHODSThis retrospective study included 47 male patients aged 16 to 63 (32.6 +/- 6.8) years treated by sacral tumor resection between January 2008 and August 2013. According to the levels of the sacral nerve roots spared in surgery, the patients were divided into four groups: bilateral S1-S3 (n=16), unilateral S1-S3 (n=21), unilateral S1-S2 (n=6), and unilateral S1 (n=4). The patients were followed up for 12 to 41 (27.2 +/- 10.9) months by questionnaire investigation, clinic review, and telephone calls about their erectile and ejaculatory function at 3, 6 and 12 months after surgery and in August 2013.

RESULTSIn the bilateral S1-S3 group, the incidence rates of EED were 31.25% (5/16), 25% (4/16), and 12.5% (2/16) at 3, 6, and 12 months respectively after surgery, with recovery of erectile and ejaculatory function in August 2013. The incidence rates of EED in the unilateral S1-S3 group were 85.71% (18/21), 71.43% (15/21), 52.38% (11/21), and 42.86% (9/21) at 3, 6 and 12 months and in August 2013, respectively; those in the unilateral S1-S2 group were 100% (6/6), 83.33% (5/6), 83.33% (5/6), and 66.67% (4/6) at the four time points; and those in the unilateral S1 group were all 100% (4/4). No statistically significant differences were found in the incidence rate of EED among the patients of different ages or tumor types (P > 0.05).

CONCLUSIONThe incidence of postoperative EED in male patients treated by sacral tumor resection is closely related to the mode of operation. Sparing the S3 nerve root at least unilaterally in sacral tumor resection is essential for protecting the erectile and ejaculatory function of the patient.

Panax notoginseng (PN) is one of the commonly used clinical medicines for cardiovascular diseases and possesses a variety of pharmacological effects. P. notoginseng saponins (PNS) are the most important bioactive components in PN. The purpose of this study was to explain the mechanism of PNS on molecular network level. 18 targets of the main medicinal ingredients of PNS were gained by virtual screening based on pharmacophores and data mining. A protein interaction network of PNS was constructed with 189 nodes and 721 interactions. By a graph theoretic clustering algorithm Molecular Complex Detection (MCODE), 14 modules were detected. Gene ontology (GO) enrichment analysis of the modules demonstrated that the roles of PNS played in cardiovascular disease related to multiple biological processes, which could represent the characteristics of traditional Chinese medicine (TCM) as a whole to regulate the disease. The results showed that the blood circulation and hemostasis efficacy of PN related with the biological processes such as positive regulation of cAMP metabolic and biosynthetic process, platelet activation and regulation of blood vessel size, regulation of T cell proliferation and differentiation and so on. Therefore, the module-based network analysis will be an effective method for better understanding TCM.

OBJECTIVETo evaluate the safety and efficiency of hemi-semi laminectomy approach for the microsurgical treatment of spinal schwannomas.

METHODSA total of 22 patients underwent hemi-semi laminectomy for the microsurgical removal of spinal schwannomas during a period of 2009 and 2011 in Affiliated Hospital of Nantong University. We retrospectively analyzed the clinical outcomes of these patients.

RESULTSOf them, 5 cases were diagnosed with cervical schwannomas, 9 with thoracic schwannomas, and 8 with lumbar schwannomas. All the tumors including two dumbbell schwannomas were totally removed without major complications. Postoperatively, all patients were followed up from 6 to 36 months. The symptoms and signs were obviously improved, and no tumor recurrence or spinal deformity occurred.

CONCLUSIONHemi-semi laminectomy is a safe and effective method for resection of spinal schwannomas.
