ObjectiveTo investigate the diagnoses of somatic diseases of inpatients with psychosis and hospitalized more then 2 years.MethodsThe material of all 350 inpatients were investigated and analyzed.ResultsThe first three psychiatric diagnoses were schizophrenia (61.32%), Alzheimer's disease (15.26%), mood disorder (4.74%). The first three diagnoses of accompanying somatic diseases were heart disease (8.68%), diabetes mellitus (8.42%), and hypertension (4.47%).ConclusionWith the changes of social environment, the disease pedigree of inpatients with psychosis changes, senile patients become more and more, and the incidence of concurrent somatic diseases gradually increases.

Objective The clinical manifestations of cerebral infarction caused by acute basilar arterial occlusion are complex.The purpose of this study is to explore the relationship between lesion location and onset symptoms of cerebral infarction caused by acute basilar arterial occlusion.Methods Fifty three patients diagnosed with cerebral infarction caused by acute artery occlusion were collected from Nanjing Stroke Registry.They were hospitalized in Jinling Hospital from January 2007 to July 2016 and were divided into sudden onset group and progressive onset group.Their clinical and digital subtraction angiography data were analyzed retrospectively.Results Middle and distal segment of the basilar artery occlusions were usually found in sudden onset group.Patients in progressive onset group were more likely to present with proximal segment of the basilar artery occlusions.Significant statistical difference was found between two groups (P<0.05).Logistic regression analysis showed that the symptoms of patients with proximal segment basilar artery occlusion tended to be progressive onset, compared with patients affected by distal segment occlusion (OR=14.77,95%CI:1.57-139.00, P=0.019).Conclusion There was significant relationship between lesion location and onset symptoms of cerebral infarction caused by acute basilar arterial occlusion.Early diagnosis and timely treatment may improve clinical prognosis in patients.

Objective To explore the effect of reconstructing unilateral cleft lip by changing the arc-shaped incision, combined with the 3D reconstruction of upper lip muscles.Methods Twenty unilateral cleft lip patients were treated by using a new surgical operation, the 3D reconstruction of upper lip muscle, to restore normal anatomy and stress of the mucous membrane, muscle and skin.Operation scar was designed for straight line, located on the philtral ridges of the contour line;phitrum and philtral ridges were rebuilt, and postoperative scar reduced.Results A lot of 20 patients had no local infection, hemorrhage, complex crack, and were stage I incision healing.Followed up for 1-8 months postoperatively, the patient's lip bow line continuity was good, with symmetrical shape and good phitrum and philtral ridges;scar was hidden on the philtral ridges of the contour line, and no obvious upper lip scar contracture found through the follow-up period.Conclusions This improved method is simple in the incision design, and less scar hidden on the philtral ridges of the contour line after operation, which can maximize the recovery of the appearance of nose and upper lip with satisfactory effect.It is a feasible improvement method of repairing unilateral cleft lip.

Objective To investigate the diagnostic significance of endoscopic findings in Henoch-Schonlein purpura(HSP),especially when abdominal pain preceded the cutaneous lesions.Methods The clinical data and gastroscopic findings in 37 cases of children with HSP were studied and analysed retrospectively in order to detect the pathological changes in the stomach and duodenum mucosa.The biopsy was taken in the pathological changeing place,and the relationship between clinical and endoscopic findings was analyzed.Results Detection rate of the pathological changes in the stomach and duodenum mucosa was 62.2%,31.3% of which experienced only cutaneous lesions,100% of which presented the acute abdominal pain.Three patients were not checked up the pathological changes.Of them,1 had arthritis,2 had Henoch-Schonlein nephritis.Characteristically endoscopic findings in the stomach and duodenum mucosa were found.The endoscopic findings included anabrosis,hyperemia,edema and hemorrhage.Conclusions Detection rate of the pathological changes in the stomach and duodenum mucosa is higher.Endoscopy is very helpful to the early diagnosis of HSP in children,especially abdominal pain presented firstly.

Objeetive To study the differences of the biological characteristics and immune regulation function of adipose mesenchymal stem cells (AMSCs)from psoriasis patients and healthy people.Methods AMSCs were isolated and cultured from human psoriatic and healthy adipose tissue,the phenotypes and cell cycle of AMSCs taken from three generation were detected by flow eytometry.Alkaline phosphate enzyme staining and oil red o staining were used respectively to identify their adipogenic and osteogenic capacity.Next,the levels of inflammation antimicrobial proinflammatory factor were detected by PCR and ELISA.Then gene expression profile of AMSCs were screen by gene expression profile chip,as so to bolting the the gene array related with immunology gene.Results There was no significant change in cell morphology,and cell surface markers were expressed high for CD29,CD44,CD73,while lower for CD31,CD45 and HLA-DR.AMSCs of psoriasis patients and healthy people both had the ability of adipogenic and osteogenic differentiation.But the cell cycle showed the third generation AMSCs proliferation rates were slower than that of normal control,as compared with healthy controls,adipogenic differentiation ability was stronger.What'more,the level of inflammatory cytokines in psoriasis group was lower than that in controls such asIL-10,IDO,TGF-β,on the contrary the levels of proinflammatory factor in psoriasis group were higher than that in controls,such as TNF-α,IFN-γ.In addition,gene chip results suggested that psoriasis group AMSCs had obvious expression differences on JAK-STAT pathway with healthy controls.Conclusions Compared with the control,there are significant differences in patients AMSCs proliferation and adipogenic differentiation ability,immune inflammation suppression control ability is weaken,this phenomenon may be associated with JAK-STAT immune pathways related to downgrade.

Objective:To investigate the expression of MEK/ERK signaling pathways in renal cell car-cinoma with bone metastasis,and to analyze the differences of expressions of VEGFR-2,MEK,ERK on the primary and metastasis tissue and its mechanism.Methods:The tissue samples were obtained from 7 renal cell carcinoma patients kindly provided by Department of Urology,Peking University People’s Hos-pital from January 1,2009 to January 1,2010.The expression of MEK/ERK signaling pathways was de-tected in the 7 renal cell carcinoma patients`primary and matched metastatic tissues with ICH,The anti-body concentrations were 1 ∶200,1 ∶25,and 1 ∶250,respectively.The mutation of the twentieth exon of the PDGFRA gene,the second exon of the K-ras gene,the fifteenth exon of the Brafgene and the se-cond exon of the MEK1 gene were detected with PCR.Results:The expression intensities of VEGFR-2, MEK,and ERK were measured by H-score [intensity (1,2,3,or 4)multiplied by the distribution (%)].VEGFR-2,MEK,and ERK expressions were divided into 3 groups according to the positive dis-tribution of the tumor cells:1,0 -5%;2,6% -50%;and 3,>50%,To assess intratumor heteroge-neity,three distinct microscopic fields (×200)from each specimen were used to evaluate the expres-sions,Subsequently,the scores were averaged to obtain a single concatenated score for each tissue. VEGFR-2,MEK,and ERK expressions were assessed by 2 independent pathologists who were blinded to the clinicopathological data.The data were expressed as the mean value of the triplicate experiments.The expressions of MEK,and ERK were higher in the metastatic tissues than in the matched RCC tissues (6.10 ±4.10 vs.1.33 ±0.51,P =0.015;9.10 ±2.24 vs.4.43 ±2.84,P =0.021 )while the ex-pression of VEGFR-2 was not different between the primary and metastatic tissues (P =0.901).No mu-tation was detected on the twentieth exon of the PDGFRA gene,the second exon of the K-ras gene,the fifteenth exon of the Brafgene and the second exon of the MEK1 gene.Conclusion:MEK/ERK signa-ling pathways may play an important role in the metastasis and the resistance of sunitinib in RCC patients with bone metastasis.

OBJECTIVETo explore the alterations of apoptosis factor Bcl-2/Bax in the early Parkinson's disease (PD) rats and the protective effect of scorpion venom derived bioactive peptide.

METHODSHealthy male SD rats (180-220 g) were randomly divided into 4 groups (n = 10): early PD model group, sham operation group, scorpion venom derived bioactive peptide control group, scorpion venom derived bioactive peptide therapy group. 6-hydroxydopamine (6-OHDA) was used to prepare the early PD rat model. The immunohistochemistry was used to detect the expression of Bax and Bcl-2 and further explore the mechanism of anti-apoptosis regarding the neuroprotective effect of scorpion venom derived bioactive peptide.

RESULTSThe results indicated that compared with the control rats, the immunostaining of Bax in the brain increased significantly while that of Bcl-2 decreased significantly in the lesion side of 6-OHDA treated rats. Interestingly, scorpion venom derived bioactive peptide could attenuate the above abnormal changes.

CONCLUSIONUp-regulation of Bax and down-regulation of Bcl-2 could participate in the early stage of PD and the anti-apoptotic mechanism could be involved in the neuroprotective effect exerted by scorpion venom derived activity peptide regarding the dopaminergic neuron in the early stage.
