Objective To study of the activities of choline acetyltransferase (ChAT ) and cholinesterase(CHE) in non-dementia vascular cognitive impairment (VCIND)patients ,and explore its mechanism .Methods Sixty-one patients with VCIND were select-ed as the research group (which accord with Rockwood diagnostic criteria for cognitive dysfunction but not meet the NINDS-ARI-IEN diagnostic criteria for vascular dementia)and 75 healthy people in the same period as the control group .Venous blood was col-lected in the early morning and serum was separated in both of the two groups .The activities of ChAT and CHE were detected by spectrophotometric method .Results The activity of ChAT in the research group(120 .94 ± 23 .93) U/mL was increased significant-ly than the control group(64 .88 ± 12 .23) U/mL(P<0 .01) ,while there was no significant difference in CHE activity between the two groups(P>0 .05) .Conclusion The increased activity of ChAT in VCIND patient and enhance the synthesis of acetylcholine , which may be a compensatory mechanism of VCIND .

Objective This prospective study was performed to evaluate the role of oral glucose toler-ance test(OGTF) in evaluating the preoperative status and postoperative complications of patients with hepa-tocellular carcinoma. Methods One hundred and twenty-eight patients with primary hepatic carcinoma (PHC) were divided into 3 groups according to the resection, in which the resection of no more than 1 seg-ment called group A, the resection of 1-2 segments called group B, the resection of more than 2 segments called group C. OGTT, routine liver function tests and Child-Pugh classification were performed in these pa-tients preoperatively. The postoperative complications were also recorded. Results Blood glucose lever of 60 min and 120 min after glucose loading test in Child B (11.23 mmol/L ± 2. 78 mmol/L, 11.79 mmol/L± 3.48 mmol/L) were significantly higher than that in Child A (8.56 mmol/L±2. 36 mmol/L, 6. 78 mmol/L ±1.60 mmol/L,P <0.01) ,but the blood glucose lever of 0 min and 30 min showed no difference. The rate of diagonis of DM in Child B was 28. 30% ,which was higher than Child A(13.33% ,P =0. 035). The OG-TT results for the L-shaped curve showed that postoperative complications were significantly higher than that of type I and P in group A and B. I-shaped and L-shaped were found ascites in group C. The cases with jaun-dice all showed L-shaped curve. When the patients' OGTT curve was P -shaped, the ascites production rate was no significantly different in these three groups. With the increase of the removal in liver, ascites produc-tion rate increased evidently in I-type and L-type(P < 0. 05). Conclusions OGTT is worthwhile to assess hepatic function reserve and postoperative complications for patients with PHC. Combination of OGTT and Child-Pugh classification has higher predictive value on hepatic function reserve.

Objective To analyze the causes of misdiagnesis and mistreatment of traumatic abdominal hernia. Methods In this study,11 cases of traumatic abdominal hernia admitted during 1971 to 2004 were retrospectively analyzed.Hernia located subcutaneously in 8 cases including incarcerated hernia in 2 csses.Hernia located intermuscularly in 2 cases with one case being incarcerated.and the other strangulated.One located retroperitoneally.Among the 11 cases,3 were simple hernia,8 were complicated with injuries of other organs. Results Eight cases were misdiagnosed,5 were operated on with wrong incision,and in one case the herniated intestinal loop,mistaken as hematoma,was incised.All these 5 cases underwent a second surgery due to failure in repairing the hernia. Condusion For traumatic abdominal wall hernia,correct diagnosis,the correct timing of operation and an appropriate incision chosen insure good therapeutic results.

Excel is electronic form software with strong function in Microsoft office. We utilize Excel software to manage the clinical teaching program. Clinical teaching program can be rapidly filled by way of duplicating, clipping, pasting, packing, arranging in order, and sieving etc. in the software, column numbers of teaching program can be added according to the need. After gathering teaching program of every research group of teaching into the total teaching program, we can conveniently arrange any column in an order and screens, so that the total teaching program was reset and optimized. The function of management of the total teaching program was so expanded that the quality and efficiency of clinical teaching management were raised.

Objective To study the expression of small breast epithelial mucin(SBEM) in the peripheral blood of the patients with breast cancer,and explore the correlation between micrometastasis and SBEM.Methods Peripheral blood samples were obtained from 92 patients with breast carcinoma,20 patients with benign breast diseases,10 patients with malignant tumor not originating from breast,and 10 normal healthy volunteers.SBEM-mRNA expression was detected by nested reverse transcription-polymerase chain reaction(Nested-RT PCR).Results Among 92 breast carcinoma patients,43(46.7%) were Nested-RT-PCR positive for SBEM-mRNA,but it was negative in all the other groups.The expression of SBEM-mRNA in peripheral blood did not correlate with ER or PR status,menstruation state or primary tumour size.but correlated with patient′s age,the state of Her-2,CEA,CA15-3 and axillary lymph node metastasis of breast cancer.Conclusions The expression of SBEM-mRNA in peripheral blood of breast cancer can be of potential use to monitor the micrometastasis of breast cancer.

Purpose To investigate the expression of TAZ and β-catenin in colorectal carcinoma and to analyze their correlation with the clinical pathological features of colorectal carcinoma. Methods The immunohistochemical method was used to detect the expres-sion of TAZ and β-catenin in 168 colorectal carcinoma specimens and 30 normal colorectal mucosal specimens. Results The positive rate of TAZ expression was significantly higher in colorectal carcinoma than that in normal colorectal mucosal (P<0. 01). The ectopic expression ofβ-catenin was significantly higher in colorectal carcinoma than that in normal colorectal mucosa (P<0. 01). The expres-sion of TAZ was correlated with degree of differentiation, lymph node metastasis, invasion depth and TNM stages (P<0. 05), and that of β-catenin was correlated with lymph node metastasis, invasion depth and TNM stages (P<0. 05). The positive expression of TAZ and the ectopic expression of β-catenin were significantly related to the 5-years survival rate ( P<0. 05 ) . The expression of TAZ was significantly positively correlated with the ectopic expression of β-catenin ( P<0. 01 ) . Conclusion Up-regulated expression of TAZ and ectopic expression of β-catenin may be synergistically involved in the occurrence, invasion and metastasis of colorectal carcinoma.

According to the latest classification of International Myeloma Working Group(IMWG),multiple myeloma(MM)is roughly classified into two groups,asymptomatic myeloma(smoldering myeloma)and symptomatic myeloma.The former is equal to the stage Ⅰ of Durie-Salmon(DS),and patients of this type only wait and see,and do not need any therapy.The later is equal to stage Ⅱ and Ⅲ of DS,and patients of this type need therapy immediately.Autologous stem cell transplantation(ASCT)is recommended by National Comprehensive Cancer Network(NCCN)for patients with stage Ⅱ or Ⅲ myeloma with good performance status in 2007.Different therapeutic regiwen should he selected for newly diagnosed MM patients according to whether ASCT is suitable or not.

Autologous stem cell transplantation (ASCT) is the standard frontline therapy for newly diagnosed multiple myeloma (MM) in patients younger than 65 years in the era of conventional chemotherapy. The use of novel drug-based chemotherapy in the in-duction, consolidation, and maintenance phases of chemotherapy has significantly improved the response rates of patients. Thus, wheth-er or not ASCT is still necessary in the era of new drugs has become controversial. Currently available data supported that ASCT should be the frontline therapy for qualified newly diagnosed MM patients and that new drugs may be applied before and after ASCT to further improve the response rate and prolong the progression-free survival of patients. Further prospective clinical trials should be conducted to clarify the role of ASCT in MM and optimize the treatment strategies involving ASCT in the era of new drugsto cure myeiona.
