Objective To establish a capillary electrophoresis method to separate ephedrine and psedudoephedrine. Methods RM-β-CD and HP-β-CD were set as additives. A capillary electrophoresis method was set up. The effects of types and concentrations of additives, the concentrations and pH values of buffered solution, running voltage and organic solvent on the separation of ephedrine and psedudoephedrine were investigated.Results Ephedrine and pseudoephedrine could be successfully separated by using either RM-β-CD or HP-β-CD as additives. When RM-β-CD was used as additive, the best separation conditions were as follows: separation voltage 10 kV, 25 mmol/L Tris-H3PO4 (pH 2.42), 20 mg/mL of RM-β-CD. Under the conditions, the resolution of ephedrine and pseudoephedrine was 1.56 and they were separated successfully within 13 min. When HP-β-CD was used as additive, the best separation conditions were as follows: separation voltage 10 kV, 25 mmol/L Tris-H3PO4 (pH 3.00), 50 mg/mL of HP-β-CD. Under the conditions, the resolution of ephedrine and pseudoephedrine was 2.73 and they were separated successfully within 15 min.ConclusionThis method is reliable, rapid and repeatable. It can be used as separation determination method for ephedrine and pseudoephedrine.

Objective: To explore the role of cytosine-phosphate-guanine oligodeoxynucleotide(CpG ODN)in enhan- cing the radiosensitivity to X-ray in mouse with Lewis lung cancer.Methods: The tumor-bearing mouse model was in- duced by injevting Lewis lung cancer cells into the right infra-axillary dermis.Thirty-two C57BL/6J mice were evenly ran- domized into 4 groups.Group A: the control group;Group B: the X-Ray radiation group;Group C: the CpG group; Group D: the CpG plus X-Ray radiation group.Group B was treated with X-Ray radiation only(3 Gy/F,on day 1,3,5, 8,10,and 12;the total dose was 18 Gy);group C was administered with CpG ODN 0.05 mg on day 1,3,5,8,10, and 12;group D was administered with CpG ODN 6h before X-ray radiation.The tumor growth and tumor growth delay (TGD)were observed in all groups.Meanwhile,the pathological change of the tumor tissue was observed with H-E staining method and the apoptosis of tumor cells were examined with the method of TUNEL.Results: The Lewis hmg cancer-bearing model was successfolly established in mice.The tumor volumes of the treatment groups were smaller than that in lhe control group(P

ObjectivesTo report pathological and genetic features of 6 Chinese families with Xlinked Charcot-Marie-Tooth disease type 1 ( CMTX1 ).Methods The index cases from 6 families with CMTX1 are males with onset of disease between 11 and 24 years old.All of them had distal leg muscle weakness,accompanied with areflexia and sensory loss in the feet.Additionally,the index 1 presented with recurrent encephalopathy and the index case 5 with cerebellar ataxia.Peripheral neuropathy was found in 12 family members,while other 7 members showed talipescavus and hyporeflexia.Sural nerve biopsies were performed in all index cases.Connexin 32(Cx32) gene was analyzed in the index cases,8 affected and 10unaffected family members as well as 50 healthy women control subjects.ResultsMild to moderate loss of myelinated fiber with axonal degeneration and regeneration clusters were found in all index cases. Thin myelin fibers were found in 5,small onion bulbs in 3 and inflammatory infiltrates in 2.Five novel mutations (I20T,I127F,D178G,A197V,403_404insT) and one L10L synonymous mutation were detected in the 6index cases and their affected family members.The same mutations,in heterozygous state,were detected in 4 female family members without clinical symptoms,but not found in 6 male unaffected family members.The same mutations were not found in healthy control subjects.ConclusionsThe CMTX1 patients in our study present predominantly axonal lesions.Frequent novel Cx32 gene mutations indicated that private mutations may be common in Chinese CMTX1 patients.

ObjectiveTo investigate expression distribution of mutant connexin 32 (Cx32) protein in human endothelial cells in patients with X-linked Charcot-Marie-Tooth disease type 1 ( CMTX1 ) .MethodsNerve biopsies were performed in 3 patients with CMTX1 and in 3 non-CMTX1 controls. Cx32 mutations of c. 379A ＞ T( I127F), c. 533A ＞ G(D178G) and c. 590C ＞ T(A197V) were identified in these 3 patients respectively.Immunofluorescent (IMF) staining of nerve blood vessel was processed with antibodies against Cx32, Yon Willebrand factor and Cx40. The mutant Cx32 was constructed in pEGFP-N plasmid (pEGFP-N1-Cx32) and was transfected in HeLa cells. Cx32 and GRP78, a marker of endoplasmic reticulum ( ER), were stained by IMF in HeLa cells to investigate expression of mutant Cx32. ResultsIn 3 control cases, Cx32 was visualized by IMF staining as dots along gap junction of vascular endothelial cells,and it was coexisted with Cx40.However, immunoreactivity of Cx32 in 3 patients was predominantly decreased and was not located in endothelial gap junction. The transfection of 3 Cx32 mutants into HeLa cells demonstrated thepathogenic changes.The cells withthemutationc. 379A ＞T found Cx32 accumulations in the cytoplasm; the cells with mutation c. 533A ＞G showed few staining positive dots surrounding the nuclear and the cells with c. 590C ＞ T showed dot-like expression of Cx32 both in the cytoplasmicand cell membrane. The mutant Cx32 was not overlapped with expression of the marker of ER.ConclusionsMutant Cx32 might cause dysfunction of endothelial gap-junctions due to the abnormal expression of Cx32 in level and location in the vascular endothelial cells of CMTX1 patients.

AIM: To determine the effect of endogenous histamine on transient forebrain ischemia-induced neuronal injury at the late phase of reperfusion using histidine decarboxylase knockout ( HDC-KO) mice.METHODS:Wild-type (WT) and HDC-KO mice were subjected to bilateral common carotid artery occlusion for 30 min followed by 3 d or 15 d of reperfusion.At different time points after reperfusion, the body weight, mortality rate, learning and memory in fear conditioning test and hippocampal CA 1 neuronal density were evaluated .RESULTS: At 1 d after reperfusion , the body weight loss was observed in both WT and HDC-KO mice.At 4 d, 5 d, 6 d and 7 d after reperfusion, the increment in the body weight of the HDC-KO mice was significantly smaller than that of the WT mice .During the period between 8 d and 14 d after reperfusion, the mortality rate of the HDC-KO mice was higher than that of the WT mice (P<0.05).At 14 d after reperfusion , the HDC-KO mice exhibited more aggravated deficits in contextual and cue memory compared with the WT mice.Correspondingly , a more severe CA1 neuronal injury in the HDC-KO mice than that in the WT mice was ob-served at 15 d but not at 3 d after reperfusion (P<0.05).CONCLUSION:Endogenous histamine may attenuate learn-ing/memory deficits and neuronal injury at the late phase of ischemia /reperfusion.However, the involved mechanisms need to be further investigated .

BACKGROUND: The gut is capable of inducing multiple organ dysfunction syndrome (MODS). In the diagnosis and treatment of critical ill patients, doctors should pay particular attention to the protection or recovery of intestinal barrier function. However, no reliable diagnostic criteria are available clinically. This study aimed to assess the changes of intestinal mucosal barrier function in surgically critical ill patients as well as their significance. METHODS: Thirty-eight surgically critical ill patients were enrolled as a study group (APACHE II>8 scores), and 15 non-critical ill patients without intestinal dysfunction were selected as a control group (APACHE II<6). General information, symptoms, physical signs, and APACHE II scores of the patients were recorded. The patients in the study group were subdivided into an intestinal dysfunction group (n=26) and a non-intestinal dysfunction group (n=12). Three ml venous blood was collected from the control group on admission and the same volume of plasma was collected from the study group both on admission and in the period of recovery. The plasma concentrations of endotoxin, diamine oxidase (DAO), D-lactate, and intestinal fatty-acid binding protein (iFABP) were detected respectively. The data collected were analyzed by the SPSS 17.0 software for Windows. RESULTS: The levels of variables were significantly higher in the study group than in the control group (P<0.01). They were higher in the intestinal dysfunction group than in the non-intestinal dysfunction group (DAO P<0.05, endotoxin, D-lactate, iFABP P<0.01). In the non-intestinal dysfunction group compared with the control group, the level of endotoxin was not significant (P>0.05), but the levels of DAO, D-lactate and iFABP were statistically significant (P<0.05). The levels of variables in acute stage were higher than those in recovery stage (P<0.01).The death group showed higher levels of variables than the survival group (endotoxin and D-lactate P<0.01, DAO and iFABP P<0.05). CONCLUSION: The plasma concentrations of endotoxin, DAO, D-lactate, and intestinal fatty-acid binding protein (iFABP) could reflect a better function of the intestinal mucosa barrier in surgically critical ill patients.

Objective To observe the clinical efficacy of acupuncture of She Medicine in treating acute lumbar sprain.Method Eighty patients with acute lumbar sprain were randomized into a treatment group and a control group,40 cases each.The treatment group was intervened by acupuncture of She medicine,while the control group received conventional medication.After successive 3-day treatment,the changes in Visual Analogue Scale (VAS) and Modified-Modified Schober (MMS) scores were observed,and the clinical efficacies were compared between the two groups.Result After the intervention,the VAS and MMS scores were significant changed in both groups (P＜0.01).The VAS and MMS scores of the treatment group were significantly different from those of the control group after the intervention (P＜0.01).The total effective rate and recovery rate were respectively 92.5％ and 70.0％ in the treatment group,versus 77.5％ and 40.0％ in the control group,and the between-group differences were statistically significant (P＜0.01).Conclusion Acupuncture of She medicine is effective in treating acute lumbar sprain,with advantages of swift action in releasing symptoms and high recovery rate.
