Objective To investigate the effect of repetitive transcranial magnetic stimulation (rTMS) on the negative symptoms of chronic schizophrenia and on the P300 component of schizophrenics' event-related potentials (ERPs).Methods Ninety convalescing schizophrenia patients were randomly divided into a 5 Hz group,a 10 Hz group and a 15 Hz group,each of 30.The three groups were treated with the corresponding 5 Hz,10 Hz or 15 Hz rTMS once a day,five times a week for five consecutive weeks.The P300 ERPs of all three groups were tested before and after the treatment.Any curative effect was evaluated using the scale for the assessment of negative symptoms (SANS).Results After the treatment,the average SANS score of the 10 Hz group was significantly different from that before the treatment and also from those of the other two groups after the treatment.After the treatment,significant improvement was also observed in the amplitude of P300 in the 10 Hz group.The treatment's effectiveness was negatively correlated with age and longer course of the disease.Conelusion rTMS at 10 Hz is the most effective of the protocols tested for improving the negative symptoms of schizophrenia and improving cognitive functioning.

Objective HLA-G widely participates in immune tolerance by its combination with immunoglobulin-like tran-scripts IL-2 and IL-4 on the surface of dendritic cells (DCs).The aim of the article was to explore the effects of recombinant adnovirus-mediated HLA-G transfection in macaca mulatta immature dendritic cells on T cell proliferation . Methods Marrow blood was collected from macaca mulattas by the puncture needle after anesthesia .Density gradient centrifugation method was applied in separating mononuclear from the extracted blood on which CD 34+cells were collected and pu-rified by means of immunomagnetic separation .Small doses of cyto-kines were added to get the immature dendritic cells after induced dif-ferentiation of CD34+cells.After the recombinant adnovirus-mediated HLA-G transfection in macaca mulatta immature dendritic cells , observation was done on the viral infection efficiency and western blot was used in detecting the expression of HLA -G in immature den-dritic cells.Taking T cells in macaca mulatta as responders and DCs transfected by recombinant adnovirus -mediated HLA-G as stimu-lators, mixed lymphocyte test was conducted .T cells were divided into 5 groups: mDC group ( mature DCs ) , imDC group ( immature DCs), imDC(L) group(addition of 100 ng/mL lipopolysaccharide after getting imDC at 7th day) , imDC(V) group (imDCs infected by recombinant adnovirus-mediated HLA-G) , imDC( L+V) group ( imDCs infected by recombinant adnovirus-mediated HLA-G along with the addition of 100 ng/mL lipopolysaccharide in culture process ) . Results We obtained the immature dendritic cells and recom-binant adenovirus of HLA-G expressed in these cells .Flow cytometry showed DC purity was up to 92.3 %, imDC purity was up to 72.39%and positive percentage of CD 4+T was greater than 80%.In comparison with imDC group ,the proliferation of stimulated T cells in mDC and imDC(L) groups was obviously intensified (P<0.01).In comparison with imDC(V) group, the proliferation of stim-ulated T cells in imDC, mDC, imDC(L), and imDC(L+V) groups was obviously intensified (P <0.01).In comparison with imDC(L+V) group, the proliferation of stimulated T cells in mDC and imDC(L) groups was obviously intensified(P<0.01). Conclu sion Im-mature DCs infected by recombinant adnovirus can inhibit the proliferation of T cells effectively .

Hepatocellular carcinoma (HCC) is the most common malignant tumor of liver.HCC is characterized with poor early detection rate and rapid progression.Therefore,bringing the patients with heavy burden of disease,though poor prognosis.Conventional treatment options can include surgical resection or liver transplantation,trans-arterial chemoembolization,ablation,and targeted therapy,but it remains unsatisfying in prognosis improvement.By years,we have come to realize the role of dendritic cells in tumor immunotherapy.Dendritic cells will become a promising treatment option in improvement of prognosis of HCC patients.In this review,we will focus on current trends and updates on dendritic cell vaccines in HCC treatment.

Bone is now regarded as an endocrine organ modulating energy metabolism. Osteocalcin, which was a traditional bone remodeling marker, especially in its undercarboxylated form, was believed to be a metabolic active molecule involving in glucose homeostasis. Bone can uptake glucose through glucose transporter 1 expressed on osteoblasts, and this process is crucial for osteoblasts differentiation and bone formation. In addition, the osteoblasts specific insulin resistance may also lead to the dysregulation of whole body glucose metabolism. Clinical investigations generally echo the findings from mice studies. More work, especially prospective clinical studies are needed to prove the clinical utility of osteocalcin and/or other bone turnover parameters as solid predictors of pancreaticβcell function and incident diabetes, as well as the potential use of osteocalcin and/or its undercarboxylated form as an anti-diabetic agent. In the 11th issue of Diabetes in 2016, a review paper entitled asRegulation of glucose handling by the skeleton:Insights from mouse and human studies was published [Diabetes, 2016,65(11):3225-3232]. With the permission of Diabetes and American Diabetes Association, we translated the most important part of this review into Chinese with a new title:The regulatory role of skeleton in maintaining glucose homeostasis.

BACKGROUNDNicotine may improve schizophrenia patient's cognitive deficit symptoms. This study was to explore the chronic effects of smoking on prepulse inhibition of the startle reflex (PPI) and P50 in the patients with first-episode schizophrenia (FES).

METHODSThe event-related potentials (ERP) recording and analysis instrument made by Brain Products, Germany, was used to detect PPI and P50 in 49 male FES patients (FES group, n = 21 for smokers and n = 28 for non-smokers) and 43 normal male controls (control group, n = 19 for smokers and n = 24 for non-smokers).

RESULTSCompared with normal controls, the FES group had prolonged PPI latency when elicited by single stronger stimulus (P < 0.05); the FES group had prolonged PPI latency and increased PPI amplitude (P < 0.05, 0.01) when elicited by weak and strong stimuli. The FES group had lower PPI inhibition rate than normal controls (P < 0.05). Compared with normal controls, the FES group had increased P50-S2 amplitude and increased amplitude ratio S2/S1 (both P <0.05). In the control group, the smokers had a tendency of increase in P50-S2 amplitude (P > 0.05) and shorter P50-S2 latency (P < 0.05) than the non-smokers. The smokers had higher PPI amplitude than the non-smokers (P < 0.05). In the FES group, the smokers had higher P50-S1 amplitude, shorter P50-S2 latency, and higher amplitude ratio S2/S1 than the non-smokers (P < 0.05, 0.01). The smokers had higher PPI amplitude than the non-smokers (P < 0.05).

CONCLUSIONSThere is obvious PPI and P50 deficits in schizophrenic patients. However, these deficits are relatively preserved in the smokers compared with the non-smokers, which suggests that long-term smoking might partially improve the sensory gating in schizophrenic patients. Whether this conclusion can be deduced to female patients requires further follow-ups.

Objective To investigate the relationship between the characteristics of psychological defense style and clinical symptoms of eating attitude in patients with anorexia nervosa patients. Methods Totally 92 ca?ses ( 46 cases of restricting type,46 cases of binge?eating/purging type,48 cases of early onset before 16 years old, 44 cases of late onset after 16 years old) meeting the Diagnostic and Statistical Manual of Mental Disorders,Forth Edition ( DSM?4) for anorexia nervosa (AN) were collected.92 gender?marriage?and education?matched normal cases in a psychiatric hospital were selected as the healthy control group(HC) .All were assessed with defensive style questionnaire(DSQ) and eating attitude test?26(EAT?26).DSQ and EAT?26 were compared between AN and HC,between early onset of AN( before 16 old years) and late onset of AN( after 16 old years) ,and between AN?R and AN?P.Then correlation study was done for the AN. Results Compared with HC,AN showed higher scores in the immature defense,neurotic defense ((4.49±1.13)vs (3.55±0.93),(4.33±0.76)vs (3.88±0.69), P<0.001), and higher EAT?26 median total and factor scores of dieting scale items,bulimia&food preoccupation scale items, oral control subscale items (P<0.01).Compared with AN?R,AN?P showed higher scores in the immature defense ((4.49±1.03)vs (4.79±1.13), P=0.01),and higher EAT?26 median total and factor score of bulimia&food pre?occupation scale items (P<0.05, P<0.01).The correlations between immature defense and EAT?26 total score,be?tween neurotic defense and EAT?26 total score were significant( r=0.472, P<0.001;r=0.315, P=0.002). The correlations between immature defense and EAT?26 dieting score, between neurotic defense and EAT?26 dieting score were significant( r=0.343, P<0.001, r=0.257, P=0.014).The correlations between immature defense and EAT?26 bulimia & food preoccupation score,between neurotic defense and EAT?26 bulimia & food preoccupation score were significant( r=0.523, P<0.001, r=0.267, P=0.010).The correlations between immature defense and duration were significant( r=0.375, P<0.001).The correlations between all defense factors and BMI were not sig?nificant( r=-0.15?0.25, P>0.05) . Conclusion AN patients tend to use more immature defense and neurotic de?fense compared with HC,and AN?P patients use more immature defense compared with AN?R. Immature defense and neurotic defense are related to the eating attitude,and the immature defense is related the duration.

Objective To investigate the risk factors of pancreatic fistula after pancreaticoduodenectomy (PD).Methods The clinical data of 186 patients who received PD at the Second Affiliated Hospital of Kunming Medical College from May 2000 to May 2010 were retrospectively analyzed.All patients were divided into pancreatic fistula group (39 patients) and non-pancreatic fistula group ( 147 patients).Risk factors of pancreatic fistula after PD were screened out from 20 factors by univariate and multivariate analysis.The univariate analysis was carried out by chi-square test or Fisher exact test,and the muhivariate analysis was done by Logistic regression.Results Thirty-nine patients were complicated with pancreatic fistula,including 26 in grade A,10 in grade B and 3 in grade C.The results of univariate analysis showed that duration of preoperative jaundicc,loss of body weight at 6 months before operation,preoperative total bilirubin level,preoperative albumin level,postoperative albumin level,length of pancreas dissected,pancreatic tube diameter,pancreatic texture and time of abdominal drainage tube pull out were high risk factors of pancreatic fistula ( x2 =34.990,20.480,8.212,10.890,13.561,11.505,13.820,4.539,36.590,P ＜ 0.05).The results of multivariate analysis showed that duration of preoperative jaundice ＞ 8 weeks,loss of body weight at 6 months before operation ≥ 10％,pancreatic tube diameter ＜ 3 mm,soft pancreatic texture and time of abdominal drainage tube pull out ＞ 5 days were the independent risk factors of pancreatic fistula ( OR =2.229,3.383,1.437,1.273,11.939,P ＜ 0.05).Conclusion Duration of preoperative jaundice ＞ 8 weeks,unconscious loss of body weight ≥ 10％ within 6 months before operation,pancreatic tube diameter ＜ 3 mm,soft pancreatic texture,time of abdominal drainage tube pull out ＞ 5 days would increase the risk of pancreatic fistula after PD.

Objective To investigate the association of single nucleotide polymorphisms (SNPs) in the SCGB3A2(secretoglobin family 3A member 2) gene promoter with susceptibility of Graves' disease.Methods One-hundred and seventy-nine SNPs within a 3.0 Mb region surrounding marker D5s2090 were scanned in a case-control study.The size of the region(s) associated with GD was then narrowed.Results Total 179 SNPs within a 3.0 Mb region surrounding marker D5s2090 were analyzed.The most significant association signal was found at SNP rs1368408 (P =3.69 × 10-5).Subsequent association analysis was then performed and the results suggested that the SNP76 (P =4.11 × 10-8) and SNP75 (P =1.37 × 10-8) in the promoter of SCGB3A2 gene may be the causal variants of GD.Logistic regression analysis suggested these 2 SNPs in this region may contribute to GD susceptibility.Conclusion A significant association seems to exist between GD with the SCGB3A2 gene.

More and more extrapancreatic actions of incretin-based therapies have been demonstrated and recently case reports have linked glucagon-like peptide-1 (GLP-1) receptor agouist therapy with the improvements in psoriasis.Psoriasis is a common skin disorder characterized by chronic inflammation.Epideminological studies have showed that patients with psoriasis exhibit increased rates of cardiovascular disease,obesity,and type 2 diabetes,owing probably to the enhanced local and (or) systemic inflammation.The observations of anti-inflammatory actions of GLP-1,which exerts direct and indirect actions on immune function,together with the improved psoriasis,offer new insights into the investigation of non-classical anti-inflammatory actions of incretin-based therapeutics and provide a new direction for the research of the novel clinical application of GLP-1.

To investigate the clinical features, genetic diagnosis, and treatment of a patient with Prader-Willi syndrome(PWS). For a case with clinically suspected PWS, methylation specific PCR(MSPCR)amplification was applied to CpG islands of SNRPN(exon α)gene locus in the 15q11-q13. Furthermore, the diagnosis was comfirmed by the method of bisulfite sequencing PCR(BSPCR). Metabolic status before and after the operation of sleeve gastrectomy were compared. Absence of amplification of paternal allele on chromosome 15q11-q13 was detected in the case by MSPCR, different from the normal control. Results of BSPCR further proved a full methylation of CpG islands in the SNRPN gene locus. Four months after sleeve gastrectomy, systemic metabolic status and ventricular function were improved. MSPCR and BSPCR were both consistent with genetic diagnosis of PWS. Weight loss surgery is expected to be a major therapy of this disease.
