The setting up of morphologic experimental centre has brougt experimental methods and means to a higher level. However, it is worth considering how to share the resource furthest,and how to exert experimental technicians’ efforts. This article intends to discuss those problems.

Objective To assess and analyze the efficacy and safety of Tegafur Gimeracil Oteracil Potassium capsule plus paclitaxel against advanced gastric cancer. Methods Totally 61 patients with advanced gastric cancer were randomly divided into two groups: the treatment group(32 cases) and the control group(29 cases). Patients in the treatment group were treated with Tegafur Gimeracil Oteracil Potassium capsule (80mg /m2 ) orally, for 14 days continuously, and paclitaxel (175mg/m2 ) on the first day. Patients in the control group were applied with oxaliplatin (130mg/m2 ) on the first day, and the same dose of Tegafur Gimeracil Oteracil Potassium capsule. The two groups both used three weeks as a cycle. Results All 61 patients were included for analysis. No complete response was ob-served. The overall disease control rate was 84. 4%, 79. 3%, respectively. The median progression free survival time was respectively 5. 6 months and 4. 9 months. The median survival time was respectively 13. 1 months and 13. 6 months. There's no significant difference between the two groups. The adverse effects were mostly tolerable, big part of which grade 1/2, mainly included hematological adverse effects, digestive system adverse effect, fatigue and so on. The incidence of neurotoxic effect of control group was higher than treatment group. Conclusion Tri-weekly paclitaxel combined Tegafur Gimeracil Oteracil Potassium Capsule is safe and effective in patients with advanced gastric cancer, which is worthy further study.

Objective To study the expression and significance of ?-catenin in keratosic dermatosis and non-melanocytic skin tumors. Methods ?-catenin expression was determined in 10 specimens of normal skin,10 cases of seborrheic keratosis(SK),26 cases of actinic keratosis(AK),17 cases of Bowen's disease(BD) and 35 cases of primary cutaneous squamous cell carcinoma(SCC) by immunohistochemical EnVision two-step staining method. Results The expression of ?-catenin was significantly higher in SK,AK,BD and SCC than in normal skin(P0.05),but that was significantly lower in SK and AK than in BD(P0.05). Conclusion The cytoplasmic and/or nuclear expression of ?-catenin may play a role in the progression from normal skin to keratosic dermatosis and non-melanocytic skin tumors.

Objective To study the prevalence of the occult hepatitis B virus infection (OBI) and the mutation of amino acid sequence in S gene of voluntary blood donors in AnHui/FuJian/Jiang Xi Province Blood centers.Methods Serologic testing for anti-HBc by ELISA was performed with HBsAg-HBV DNA+ samples from voluntary blood donors in three province blood centers.The S region of HBV of those samples was amplified and sequenced.The genotype and mutation of amino acid sequence were analyzed by MEGA6.Results 21 in 123046 blood donors from AnHui Province blood center were HBsAgHBV DNA+,the prevalence of OBI was 0.017％,and 76.2％ of these-OBI samples was positive in anti-HBc,S region was amplified by nest-PCR in 15 OBI samples,8 of them were B genotype,the others were C genotype.39 samples of 51 OBI blood donors from FuJian Province blood center were anti-HBc positive,16 samples of those OBI donors were amplified S region,14 were B genotype,the others were C genotype.There are 30 OBI blood donors from JiangXi Province blood center,24 of them were anti-HBc positive,S region was amplified in 4 samples,1 was B genotype,the others were C genotype.Of all 35 OBI samples,26 showed amino acid mutation,which was in MHR region of S gene,especially in HBV α epitope.Conclusion The rate of prevalence of OBI in AnHui Province was 0.017％,there was also certain OBI infection in FuJian and JiangXi Province.In the OBI samples which were amplified S region,the positive rates of anti-HBc in three blood centers were 73.3％,93.8％,100％.B Genotype was the main HBV genotype.The mutation in MHR region of S gene,especially in HBV α epitope,may be one of the reasons to cause OBI.

OBJECTIVETo observe the therapeutic effect of Xuefu Zhuyu Decoction (XZD) on patients with sudden deafness (SD).

METHODSSixty patients with SD were treated with XZD, and the changes of brainstem auditory evoked potential (BAEP) and transcranial Doppler (TCD) parameters in them were detected before and after treatment and analyzed statistically.

RESULTSI, III and V waveform and peak latency (PL) of BAEP, velocity of vertebral basilar arterial blood flow and parameters of cerebral blood flow in SD patients were all improved to different levels after treatment with XZD.

CONCLUSIONTCM formula for promoting blood circulation to remove blood stasis can improve BAEP and TCD parameters in SD patients; BAEP detection and TCD parameters can reflect nerve function and blood-supply state of internal ear and brain stem, and therefore are of great importance in guiding the clinical treatment and assessing the prognosis.

Objective To observe the therapeutic effect of Shengxuenin(SXN) in treating iron deficiency anemia (IDA).Methods 60 cases with IDA from January 2007 to June 2008 were treated with SXN,2 pellets Tid per os for 30 days.The value of erythlrocyte count (RBC),haematoglobin(Hb),hematocrit(HCT),mean corpuscular volume(MCV).mean corpuscular haematoglobin (MCH),mean corpuscular-hemoglobin concentration (MHCH),Reticulocyte(Ret) was observed at the first week,the second week,the third week and the fourth week of the treatment.Results Reficulocyte count started to increase at the lst week and haematoglobin count started to increase at the 2nd week.Haematoglobin,mean corpuscular volume,mean corpuscular haematoglobin and mean corpuscular-hemoglobin concentration returned to normal at the 4th week.The gastrointestinal side effects of this thempy were fewer than treated with other chalybeate medicines.Conclusion SXN was effective in the treatment of IDA and had little gastrointestinal side effects.

BACKGROUND:Abnormal hippocampal neurogenesis during aging has been reported to result in learning and memory dysfunction. But its mechanism is unclear.
OBJECTIVE: To understand the changes of mouse neurogenesis in the hippocampal subgranular zone during aging.
METHODS:C57BL/6 mice 2, 6 and 20 months of age were used. Immunochemistry was used to count the number of neural stem cels (nestin+), neuroblasts (Doublecortin+, DCX+), and proliferative cels (proliferating cel nuclear antigen+, PCNA+) in the hippocampal subgranular zone. mRNA expressions of aging-related genes, p19Arf and p21Cip1/Waf1, in the hippocampus were detected by reverse transcription-PCR.
RESULTS AND CONCLUSION: Compared with the young and middle age groups, the number of PCNA+ cels, nestin+ and DCX+ cels in the hippocampal subgranular zone of the aged group decreased dramaticaly; the expression of p19Arf and p21Cip1/Waf1 mRNA increased in the aged group. Proliferation activity, the number of neural stem cels and neuronal differentiation al decreased. These findings indicate that the decline of hippocampal neurogenesis may be associated with increased expression of aging-related genes p19Arf and p21Cip1/Waf1 in the p19Arf-Mdm2-p53-p21Cip1/Waf1pathway.

Objective To study the recovery of the peripheral lymphocyte subsets in patients underwent allogeneic peripheral blood stem cell transplantation (allo-PBSCT) and guide the prevention and treatment of infection. Methods Indirect immunofluorescence assay was used to detect the lymphocyte subsets, such as T cell subsets (CD3, CD4, CD8). B cell (CD19) and natural killer cell(CD56) at 1, 3, 6, 12, 18months post transplantation, in the meantime, lymphocyte subsets of 32 samples from healthy blood donors were tested as normal control values. Results CD+3, CD+4 and CD+8 ceils significantly decreased than that of normal control at 1 month post transplantation, the recovery of CD+3 T cells was within 3-12 months, CD+4 and CD+8 T cells recovered to normal at 6 months and 3 months post transplantation respectively, CD+4/CD+8 ratio were not significantly lower than that of normal control at different stages, CD+4/CD+8 ratio reversed only at 6 months post transplantation. CD+19 and CD +56 T cells recovered quickly and they were more than normal proportion at 3 months post transplantation. The CD+3, CD+8 T cells and CD+4/CD+8 ratio were statistically higher in HLA haploidentical allo-PBSCT patients than that in HLA identical allo-PBSCT at 3 months post transplantation. There were no difference between the two groups at 1, 6, 12, 18 months post transplantation.The patients with cGVHD had significantly higher CD+4 cells than those without cGVHD at 1 month after transplantation. There was no significant difference in all of the lymphocyte subsets at 3, 6, 12, 18 months after transplantation between them. Conclusion Allo-PBSCT has a hastened immune reconstitution, which was not delayed by the incompatibility of HLA and the development of cGVHD.
