Objective To explore the correlation of electrophysiological features with clinical manifestation in patients with diabetic peripheral neuropathy (DPN).Methods The clinical data of 306 patients with DPN undergoing nerve conduction study (NCS) during May 2013 to June 2015 were retrospectively analyzed.Among 306 patients,304 were type 2,and 2 were type 1 diabetes with a mean age of 64.1 years and disease duration of 1 week-31 years.The relationship between the electrophysiological features and clinical manifestations was evaluated.Nerve conduction studies and F-wave and in sympathetic skin response were analyzed.Results ① NCS in lower limbs presented more abnormalities than that in upper limbs.There was the highest prevalence of not elicited sensory potential in Tibial nerve [56.9％(174/306),x2 =175.9] and the highest prevalence of not elicited motor potential in peroneal nerve [7.8％(24/306),x2 =1 103.1].Amplitude abnormality was more severe in sensory nerve than that in motor nerve[41.4％ (507/1 224) vs.10.8％ (132/1 224),x2 =559.2].The ratio of abnormal motor conduction velocity or distal latency was higher than that of amplitude decreased [22.9％ (280/1 224) vs.10.8％(132/1 224),x2 =1 077.4].② The abnormal ratios of the shortest F-wave latency was lower than that of the prolonged distal latency in median and tibial nerve [5.4％ (33/612) vs.20.6％ (126/612),x2 =607.6].③ The abnormal ratio of sympathetic skin response (SSR) in lower limbs were higher than that of upper limbs [40.2％ (246/612) vs.27.3％ (167/612),x2 =129.4,P ＜ 0.001],abnormal ratio of amplitude was higher than that of the prolonged latency [30.1％ (368/1 224) vs.4.7％ (58/1224),x2 =1040.5,P ＜0.001].Among the 99 cases presenting abnormal SSR in upper limbs,32 cases were normal in conventional NCS.Among the 127 cases presenting abnormal SSR in lower limbs,7 cases were normal in conventional NCS.④Disease course and glycosylated hemoglobin values were positively correlated with the distal motor latency,and negatively correlated with the nerve conduction velocity and amplitude.Conclusion Electrophysiological features of DPN is mainly shown in axon of the distal sensory nerve.Long duration and hyperglycemia may lead to more abnormalities in electrophysiological tests.

Objective To assess the irregular shape of hematoma with math methods,which is one of the risk factors of hematoma enlargement.Methods We reviewed images data of patients with spontaneous intracerebral hemorrhage treated nonsurgically who underwent initial computed tomography (CT) within 6 hours and repeated CT within 48 hours of onset.The area(s),the circumference(L),the greatest diameter(A)and the transverse diameter(B)of the greatest hemorrhage CT slice was measured.The formula X=L/S waft used to calculate the value.We calculated the area(S1)and the circumference (L1) of the ellipse with A as its long diameter and B as its short diameter.The formula X1=S1/L1 was used to calculate the value. We used formula R=X/X1 to assess the irregular hematoma shape.The relationships between hematoma enlargement and R was analyzed. Results Thirty-one patients(25.8%) showed enlarged hematomas after admission.The larger the value of R,the more irregular the shape of hematoma.When R≥1.3,the shape of the hematoma was significantly irregular.36.0% patients with R≥1.3 had hematoma enlarged.compared with only 18.6% those with R<1.3(χ2=4.62,P=0.032).Conclusions The irregular shape index R Can be used to assess the shape of a hematoma. A particularly high likelihood of hematoma enlargement is observed in patients with an irregularly shape index R≥1.3.

Objective To evaluate the effects of asymptomatic arteriovenous fistula closure on left ventricular morphology and function in renal transplant recipients.Methods Between March 2007 and March 2011,a total of 60 patients undergoing consecutive kidney transplantation with asymptomatic arteriovenous fistula were divided randomly into two groups: arteriovenous fistula closure group,and non-arteriovenous fistula closure group.By using echocardiography,the changes in CO,CI,EF,LVEDV and LVMI were analyzed.Results At 12th month after transplantation,the values of CO,LVEDV and LVMI were significantly lower than those before transplantation (P＜0.05).The value of CI also showed a tendency to decrease (P＞0.05),and the value of EF was increased significantly (P＜0.05).At 6th month after arteriovenous fistula closure (18 months after transplantation),the values of CO,CI,LVEDV and LVMI were significantly lower than those before arteriovenous fistula closure (12 months after transplantation) (P＜0.05),and the value of EF was increased significantly (P＜0.05),but the values of CO,CI,EF,LVEDV and LVMI remained unc(b)anged in controls (P＞0.05).At 18th month after transplantation,the values of CO (4.4 ±0.8 L/min),CI [3.0 ± 0.8 L·min-1·m-2],LVEDV (110.0 ± 17.4 ml) and LVMI (114.7 ± 42.5g/m2) in trial group were significantly lower than the values [CO: 5.1 ± 0.9 L/min,CI: 3.5 ± 1.0L·min-1·m-2,LVEDV: 121.4±19.3 mL,LVMI: 138.4±44.1 g/m2] in controls (P＜0.05),and the value of EF (75.2％ ± 7.4％ vs.70.5％ ± 8.2％) significantly higher (P＜005).Conclusion In both groups,kidney transplantation benefits significantly the regression of cardiac mass,cardiac index and left ventricular dimensions,but closure of asymptomatic AVF induces more significant regression.

Objective To investigate the change of dynamic expression of t-PA and PAI-1 during early venous crisis after free perforator flap transplantation.Methods Thirty healthy New Zealand white rabbits weighed 2.5-3.0 kg were chosen and randomly divided into experimental group (n =15) and control group (n =15).Free transplantation of superficial epigastric artery perforator flap (SEAPF) was implemented in all rabbits firstly.Then the model of venous crisis was established by ligating the anastomosis vein in order to interrupt venous blood outflow in experimental group.The blood supply of all flaps was monitored by observing their color,swelling degree and the filling reaction of the capillaries after operation.Peripheral blood was drawn from femoral artery at different time point for measuring the concentration of t-PA and PAI-1 by Elisa.Partial flap tissue was harvested for pathological examination at corresponding time point.Data analysis was performed by using SPSS 17.0 statistical software.P ＜ 0.05 was considered statistically significant.Results One rabbit died of anesthesia,and the venous congestion was observed in 1 rabbit in control group.The models of free transplantation of SEAPF and venous crisis were established successfully in the remaining rabbits.No significant appearance change was observed within 1 h after the outflow vein being ligated,while typical appearance of venous crisis could be observed 2 hours after the outflow vein being ligated.Compared with the control group,the concentration of t-PA was lower,but the concentration of PAI-1 was higher in experimental group at 2 hours,4 hours,6 hours,8 hours after the outflow vein being ligated(P ＜ 0.05).However,there was no obvious differences between two groups at other time points (P ＞ 0.05).The pathological examination showed the red cells gradually got together and adhered to the venous wall,eventually the microcirculation had been blocked completely and theflap became necrosis after venous crisis being occurred.Conclusion t-PA and PAI-1 can't be used to diagnose early venous crisis of perforator flap transplantation.

AIM: To investigate the immunologic mechanism of CXC chemokine ligand 10(CXCL10) and its receptor CXC chemokine receptor 3 (CXCR3 ) involved in the process of endometriosis (EM). METHODS: Serum samples were collected from 3 groups; EM patients without operation (n = 76) , EM patients with operation (n = 10) and the normal control persons (n =76). CXCL10 and CA12S concentrations were detected by means of ELISA and chemilumino-metry. Cell surface antigens on the activated PBMC - CD3 and CXCR3, as well as CXCR3 subgene - CXCR3A and CX-CR3B were tested by flow cytometry (FC) and RT - PCR when PBMC was separated from women with EM ( n = 10) and without EM (n = 10), and then activated. RESULTS: Serum CXCL10 concentrations between three groups were signifi-canly different (P < 0.05). Compared to normal control group, although the supernatant CXCL10 concentration and CD3~+ /CXCR3~+ PBMC number in EM group has no significant difference (P >0.05) , highly expressed CXCR3B in EM group rather than CXCR3A was observed. CONCLUSION: CXCL10 in women with EM is low, indicating that it plays a vital role in the process of EM and immune system of the women with EM is defected and impaired. The immunoreactivity of PBMC from both EM patients and normal person is same to activated signal, but the productions are different: PBMC in EM group mainly express CXCR3B but PBMC in normal person mainly express CXCR3A after activation, which may be one of the immune mechanisms that EM escapes from immunological lethal effect of the infected host.

AIM: To evaluate the implication of CXCL10-loop3-EGF fusion protein for the activities of targeting tumor and anti-angiopoiesis. METHODS: RT-PCR was preformed to amplify CXCL10 coding sequence from PBMC activated by IFN-γ. CXCL10-loop3-EGF fusion gene, which was conducted by Over-Lap Extention PCR, was hinged up with plasmid pTG19-T, transfected to E. coli DH5α and processed positive colony selection. After ligated with plasmid pET32a(+), recombinant CXCL10-loop3-EGF fusion gene was then transfected to E. coli Origami B (DE3) and induced to express its coding fusion protein his-CXCL10-loop3-EGF. The recombinant fusion protein CXCL10-loop3 -EGF was purified by His-bind affinity chromatograph, enterokinase cleavage, ultrafiltration and dislysis. The transwell chemotatic test and HUVEC angiopoiesis inhibition test were performed to determine the anti-tumor responses and anti-angiopoiesis activity of CXCL10-loop3-EGF fusion protein. RESULTS: CXCL10-loop3-EGF fusion protein was successfully constructed and confirmed by SDS-PAGE analysis and Western blotting. Significant PBMC chematatic activity and HUVEC anti-angiopoiesis activity were observed. CONCLUSION: CXCL10-loop3-EGF fusion protein, which has perfect anti-tumor activity, is successfully constructed.

Objective To investigate serum uric acid (UA) levels and related clinical features in patients with high risk syndrome of neuromyelitis optica. Methods UA levels were measured in 51 patients with high risk syndrome of neuromyelitis optica including 34 with longitudinally extensive transverse myelitis (LETM) and 17 with optic neuritis (ON), 48 with neuromyelitis optica (NMO), 45 with other neurological diseases (OND) and 65 with healthy controls (HC). The disability severity was assessed by the expanded disability status scale (EDSS). Spinal lesions were viewed by MRI. Serum aquaporin-4(AQP4) antibody was tested in cell based immunofluorescence assay. Results Serum UA levels in LETM ( ( 189. 84 ±85. 65) μmol/L) and ON patients ( (222. 12 ±61.68) μmol/L) were significantly lower than that in OND ((315.90±71.36) μ mol/L) and HC ((291.05 ±76.64) μ mol/L) subjects (P＜0.01). No difference was found between LETM, ON and NMO groups. UA levels were significantly lower in females ( ( 158.24 ±55.92), (187.00±47.52), (198.21 ±62.62), (274.51 ±70.66)and (243.26±60.65) μmol/L)than in males ( ( 262. 09 ± 101.63 ), ( 262. 45 ± 62. 13 ), ( 298.90 ± 74. 14 ), ( 355.37 ± 50. 30 ) and (340. 34 ±58. 23) μmol/L) in all groups (t=3. 183, 2.578, 4.356, 4.365 and 6.579, all P＜0.05).UA levels in patients with high risk syndrome of NMO were not correlated with mono or relapse course,duration or status of serum AQP4 antibody. UA were negatively correlated with EDSS in patients with LETM (r= -0.714, P＜0.01). Conclusion Lower serum UA levels were found in patients with high risk syndrome of NMO and related to more severe symptoms in LETM group.
