Objective To explore the mechanism of Xiaotansanjie recipe on MKN-45 human gastric cancer orthotopic transplantation tumor with microsatellite instability. Methods MKN-45 human gastric cancer cell line was used to establish subcutaneous tumor model in nude mice as an experimental model which passed three generations of tumor source. Then OB glue was used to establish human gastric cancer orthotopic xenograft model. Twenty model nude were divided into model group and Xiaotansanjie recipe group (treated with Xiaotansanjie recipe). After 6 weeks of treatment intervention, tumor weight was measured, inhibitory rate was calculated and microsatellite instability (D17S250, D2S123, D5S346, Bat-25 and Bat-26) was detected. Results The tumor weight in Xiaotansanjie recipe group was significantly lower than that in model group (P<0.01). The tumor-inhibition rate was 40.84%. Five microsatellite markers (D17S250, D2S123, D5S346, Bat-25 and Bat-26) were amplified in the tumor tissue of model group, and microsatellite markers D2S123, D5S346 appeared some prolong and reduction. Microsatellite markers (D2S123, D5S346) mutation was stabilized after 6 weeks treatment of Xiaotansanjie recipe. Conclusion Xiaotansanjie recipe can inhibit the MKN-45 human gastric cancer orthotopic transplantation tumor by down-regulating the microsatellite instability.

Objective:To probe essence of TCM syndrome of gastric carcinoma from gene protein expression.Methods:Based on the collected data from pre-operative patients of gastric carcinoma,their TCM syndromes were determined by means of TCM syndrome classification criteria.E-cadherin gene protein expressions in tumor tissue after operation of gastric cancer were detected with EnVision two step immunohistochemical method.Results:The expression rate of E-cadherin was 90% in 100 cases of gastric carcinoma,with significant difference among different syndrome types(P

To probe into a method for establishing the fuzzy mathematical model for syndrome differentiation of gastric cancer.

Objective To investigate the effects of femoral nerve block combined with celecoxib on postoperative analgesia in elderly patients with hip fracture. Methods Two hundreds ASA -Ⅲ patients aged 65-89 yrweighing 35-90 kg undergoing hip fracture surgery were randomly divided into 4 groups ( n = 50 each):control group (group Ⅰ ), femoral nerve block group ( group Ⅱ ), celecoxib group (group Ⅲ ) and femoral nerve block +celecoxib group (group Ⅳ ). Operations were performed under combined spinal-epidural anesthesia. Groups Ⅲand Ⅳ were given oral celecoxib 400 mg at 1 h before operation, and 200 mg at 1 and 2 days after operation twice a day. Groups Ⅰ and Ⅲ received iv injection of sufentanil 0.06 μg/kg before the patients were placed in the position, while in groups Ⅱ and Ⅳ femoral nerve block was performed using a nerve stimulation with 20 ml of 0.5%ropivacaine and 10 min later the patients were placed in the position. All the patients received postoperative patient-controlled intravenous analgesia with sufentanil to maintain visual analogue scale score ≤ 3. The condition of satisfactory analgesia and sufentanil consumption within 24, 48 and 72 h were recorded. The coagulation function was measured on the day of admission to the hospital, at 1 day before operation and at 4 days after operation. Cardiac troponin Ⅰ (cTnI) concentrations were measured before operation, at the end of operation and at 1 day after operation. Postoperative complications was observed and recorded. Results Compared with group Ⅰ , the consumption of sufentanil was significantly reduced during each period in group Ⅳ ( P ＜ 0.01 ). Compared with group Ⅱ , the consumption of sufentanil was significantly reduced within 48 and 72 h after operation (P ＜ 0.05), while no significant change was found within 24 h after operation in group Ⅳ ( P ＞ 0.05). Compared with group Ⅲ , the consumption of sufentanil was significantly reduced within 24 h after operation ( P ＜ 0.05 ), while no significant change was found within 48 and 72 h in group Ⅳ ( P ＞ 0.05). The level of satisfactory analgesia was significantly higher in group Ⅳ than in the other three groups, and in groups Ⅱ and Ⅲ than in group Ⅰ ( P ＜ 0.05). The 4 groups were comparable with respect to the increased rate of cTnI concentrations at the end of operation and after operation, and perioperative blood coagulation. No postoperative complications were found in the 4 groups. Conclusion Femoral nerve block combined with celecoxib can reduce postoperative opioid consumption and enhance postoperative analgesia in elderly patients with hip fracture.

Objective To observe the effects ofXiaotan Sanjie Decoction on ultramicrostructure in MKN-45 human gastric cancer orthotopic xenograft;To discuss its mechanism for gastric cancer. Methods MKN-45 human gastric cancer cell line was used to establish subcutaneous tumor model in nude mice as an experimental model which passed three generations of tumor source. Then OB glue was used to establish human gastric cancer orthotopic xenograft model. 40 model nude mice were divided into control group, model group (received gavage with saline),Xiaotan Sanjie Decoction group (received garage withXiaotan Sanjie Decoction) and Tegafur group (received gavage with Tegafur), 10 mice in each group. Mice in the control group were under normal diet, without medicine intervention. After 6 weeks of treatment intervention, tumor weight was detected, inhibitory rate was calculated, the ultrastructural changes of gastric cancer cells were detected through transmission electron microscopy.Results The tumor weight inXiaotan Sanjie Decoction group was significantly lower than that in control group and model group (P<0.05,P<0.01). The tumor inhibition rate was 46.2%. Under the electron microscope, MKN-45 gastric cancer cells strain changed to typical apoptosis.ConclusionXiaotan Sanjie Decoction can lead to apoptosis effects on MKN-45 human gastric cancer orthotopic xenografts. All evidences indicate that inducing apoptosis may be one of the most important mechanisms ofXiaotan Sanjie Decoction in treating gastric cancer.

The oligonucleotide primer having the 5’\|GCCGGTTATGGC AGCACGCTGACC\|3’ was synthesized,which encodes a main repetition motif of protein produced by the inaZ gene.PCR of the primer in the DNA of INA - and INA + bacteria and fungi was done.All of the DNA of INA - and INA + bacteria and fungi expressed bands,the results show that the primer did not work for distinguishing the INA - and INA + organisms and for identification of the ice nucleation activity of the INA organisms by the size and brightness of the PCR products.

To explore the mechanisms of Xiaotan Sanjie Decoction (XTSJD), a compound traditional Chinese herbal medicine, in inhibiting the tumor growth and preventing recurrence by testing the protein expressions of interleukin-8 (IL-8) and its receptors chemokine receptor 1 (CXCR1) and chemokine receptor 2 (CXCR2) in gastric tumor xenografts and gastric tissue adjacent to the tumor in mice.
