Objective A preliminary study on a new discovered proteomic fingerprint correlated with anxiety disorders, which M/Z range from 15000 to 16800. Methods 221 cases of neoplasm patients from April of 2004 to now were divided into anxious group and non-anxious group according to their scores using self-rating anxiety scale (SAS), and all the patients' sera were detected utilizing SELDI-TOF-MS. The data were analyzed with supported softwares. Results Compared the mass spectra of anxious group(n=49) and non-anxious group (n=172), 2 clusters were captured which M/Z range from 15 000 to 15 380 and 15 700 to 16 800 respectively. The coincidence with SAS was 75.51%. The M/Z range from 15 700 to 16 800 was the most frequent, then the second range from 15 000 to 15 380 and 15 700 to 16 800 which was doublet cluster, the least range from 15 000 to 15 380. The same fingerprints were captured in non-anxious group and their intensity was different. Conclusion The M/Z range from 15 000 to 16 800 was protein fingerprint correlated with anxiety disorders.

Objective To evaluate the application effect and value of four kinds of neuroendoscopic operation mode in the treat-ment of hydrocephalus .Methods The four kinds of neuroendoscopic operation mode ,including endoscopic third ventriculostomy , septostomy of the septum pellucidum ,cyst ventriculostomy and ventrideperitoneal cavity ,were selected in 58 cases of hydrocephalus according to the indications .The treatment effects were analyzed and the application value was evaluated .Results Among 58 cases of hydrocephalus ,50 cases were significantly improved after operation ,the total effective rate was 86 .21% ,2 cases appeared some complications .The four kinds of operation mode could better treat hydrocephalus .Conclusion Neuroendoscopy is an ideal method in treating hydrocephalus and has the advantages of the slight trauma and fewer complications ,which is a method deserving to be promoted in clinic .

It has been well-known that intravenously infused hematopoietic stem and progenitor cells can home to the bone marrow and reconstitute hematopoiesis. However, little is understood about the homing efficiency or percentage of infused stem and progenitor cells. In order to examine distribution pattern of infused hematopoietic cells in the organs and tissues, a direct assay system to trace transplanted cells in vivo by employing PKH-26, a red fluorescent membrane dye, to label hematopoietic cells in inbred strain of mice transplanted cells (stem cell antigen-1 positive subpopulation cell, Sca-1(+) cells) was introduced. The numbers of labeled cells was measured by means of flow cytometry and fluorescence microscopy. The early fate of infused Sca-1(+) donor bone marrow cells after intravenous administration in a allogeneic mouse model was examined. The presence of infused donor cells with the fluorescent dye PKH-26 was evaluated within 60 hours in hematopoietic organ (bone marrow and spleen) and non-hematopoietic organ (lungs and liver) of recipients. The data showed that (1) Following intravenous infusion, Sca-1(+) donor bone marrow cells were detained in lungs shortly. (2) Sca-1(+) donor bone marrow cells localized to both hematopoietic organ (bone marrow and spleen) and non-hematopoietic organ (lungs and liver) for periods of up to 60 hours following infusion, however, the number of donor hematopoietic cells localized to bone marrow was more than that localized to non-hematopoietic organ (P < 0.05). These results indicated that there were also donor early hematopoietic cells in non-hematopoietic organ of recipients at the homing phase in allo-BMT mice.

In order to explore the improvement of seeding efficiencies of infused donor hematopoietic cells to bone marrow in bone marrow transplantation, two recipient groups of syngeneic rat model which received transplanted cells labeled with PKH-26, a red fluorescent membrane dye, by aortic or intravenous administration (2 x 10(7) nucleate cells per recipient rat) respectively, were assayed; at selected times following BMT, partial recipient rat were euthanized and then measured the numbers of PKH-26 labeled cells in recipient rat marrow samples by means of flow cytometry. The results showed that the homing indices of donor hematopoietic cells in aortic group and intravenous group were (14.52 +/- 1.07)% and (10.49 +/- 0.72)% at 30 hours after BMT, respectively (P < 0.05). The results indicated that the number of donor hematopoietic cells localized to recipient bone marrow infused by aortic route is more than that infused by intravenous route.

Objective To evaluate the diagnostic rate and treatment effect of close renal trauma.Methods The clinical data of 129 cases of close renal trauma were analyzed retrospectively. Results Lumbago or bellyache occurred in 109 cases,hematuria 113 cases,coexistent injuries of other organs 81 cases. 129 cases were examined by type B-ultrasonography, 102 cases by CT scan open operation on 17 cases and others were treated non-operatively. 118 cases have been followed up for 3 months to 56 months with normal urine routine and IVU.Conclusions Usually urine inspection and B-ultrasonography were simple,instant reliable and safe. The accurate diagnosis rate was higher with CT scanning,CT scan was helpful in detecting the degree of renal injury and any coexistent injuries,and to estimate the treatment effect. Laparotomy should undertaken for the case of severe injury or with coexistent injuries in rime.

Objective To explore the association between genetic polymorphisms and haplotypes of tumor necrosis factor-related apoptosis inducing ligand (Trail) and ulcerative colitis (UC).Methods A total of 331 patients with UC and 832 age and sex-matched healthy controls were collected.After Trail gene was amplified by PCR,the genetic polymorphisms of three single nucleotides (G1525A/G1588A/C1595T) in 3' non coding regions of Trail gene were examined by direct sequencing.The relation between Trail haplotype and UC was analyzed.Results Compared with control group,the frequencies of variant allele A and genotype GA+ AA in Trail G1525A were significantly lower in UC group (both P＜0.01).The frequencies of variant allele A and T in Trail G1588A and C1595T were also significantly lower in UC group than that of control group,and the difference was statistically significant (both P ＜ 0.01 ).In mild and moderate UC patients,the frequencies of variant allele T and CT+TT in Trail C1595T were 49.15％ and 64.51％,in severe UC patients were 72.37％ and 84.21％,and the differences were significant between the two groups (OR=2.710 and 2.935,95％CI:1.598～4.596 and 1.188～7.249,all P ＜0.05).In severe UC patients,the frequency of variant allele A in Trail G1525A was 48.69％,which was higher than that of mild and moderate patients (35.16％,OR=1.750,95％CI:1.082～2.830,P=0.021).In UC group,the frequency of AAT haplotype was significantly lower than that of controls (43.09％ vs 58.41％,P＜0.01).The frequency of GAT haplotype was significantly higher in UC group (10.15％vs 0.18％,95％ CI:0.005 ～ 0.051,P＜ 0.01).Conclusion The genetic polymorphisms and haplotypes of Trail (G1525A/G1588A/C1595T) gene may be closely correlated with the susceptibility to UC.
