ABSTRACT

Objective To investigate the role of metastatic lymph node ratio (MLR) in the evaluation of prognosis of patients with gastric cancer (GC) at different lymph node numbers examined.Methods Clinical data were reviewed retrospectively in a total 535 patients who underwent surgery for GC.Spearman correlation analysis between MLR or number of metastatic lymph nodes (N) and examined lymph node numbers,Kaplan-Meier method was used for comparison survival rates of N stage and MLR stage.A receiver operating characteristic (ROC) curve was used to evaluate the role of N stage and MLR stage in the prognosis of GC patients.Results Metastatic lymph node ratio and number of metastatic lymph nodes correlated with the examined lymph node numbers (r =0.146,r =0.378,P < 0.01,P < 0.001).The 5 year survival rate of MLR0,MLR1,MLR2 and MLR3 patients were 57.5%,69.9%,40.0% and 21.7% respectively when examined lymph node numbers < 6 (P < 0.01).The 5-YSR of MLR0,MLR1,MLR2 and MLR3 patients were 86.8%,59.2%,35.8% and 39.2% respectively when between 6-10 (P <0.001) and the 5-YSR of MLR0,MLR1,MLR2 and MLR3 patients were 88.7%,62.5%,0 and 17.7% respectively when they > 10(P <0.001).AUC of MLR staging was 0.68 ±0.05 when the numbers < 6 (P < 0.001).AUC of MLR staging was 0.72 ± 0.04 at numbers 6-10 (P < 0.001).AUC of MLR staging was 0.79 ± 0.03 when numbers > 10 (P < 0.001).Conclusions MLR was less influenced by lymph node number examined than N.MLR stage has potential superiority to that the N stage in assessing prognosis of GC patients,especially for patients with more than 6 lymph nodes examined.

ABSTRACT

Objective To investigate the effect of the pregnancy factor on the line drawn between the highest points of the two iliac crests ( T line) corresponding to the vertebral level in a multicenter clini?cal comparative study. Methods Hospitalized patients selected from the obstetric department or gynecolog?ical department, of American Society of Anesthesiologists physical statusⅠorⅡ, were divided into preg?nancy group ( group P ) and non?pregnancy group ( group NP ) . The patients were placed in the lateral posi?tion with their back vertical to the bed surface, the patient′s thighs were at an angle of approximately 90 de?grees to the trunk, and hip flexion was employed by flexing the patient′s knees to the chest. To determine the highest points of the two iliac crests, a line ( T line) was drawn between the highest points using a wire?reinforced epidural catheter. And another vertical line ( T′line) was made between the highest point of the iliac crest on the upper side ( not the side in the lateral position) and the ground. Ultrasonography was per?formed to identify and record the level of T line and T′line corresponding to the spinous process and lumbar interspace. Results A total of 1 763 cases completed the study, and there were 905 cases in group P, and 858 cases in group NP. Compared with group NP, the rate of T line at L3 spinous process and L3,4 in?terspace was significantly increased in group P ( P<0.05) . Compared with T′line, the rate of T line at L2,3 interspace and L3 spinous process was significantly decreased, and the rate of T line at L4 spinous process, L4,5 interspace and L5 spinous process was significantly increased in group P, and the rate of T line at L3 spinous process, L2,3 interspace and L3,4 interspace was significantly decreased, and the rate of T line at L4 spinous process and L4,5 interspace was significantly increased in group NP (P<0.01). Conclusion The level of T line corresponding to the vertebral level is significantly higher in the pregnant patients than in the nonpregnant patients.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects of β-elemene in suppressing the proliferation and apoptosis of SGC7901 gastric cancer cells in vitro and explore the underlying mechanisms.</p><p><b>METHODS</b>Using MTT assay, flow cytometry, and clonogenic survival assay, we assessed the effects of β-elemene on the viability, apoptosis, cell cycle distribution, and clonogenic survival of gastric cancer SGC7901 cells and gastric mucosal epithelial GES-1 cells. Western blotting was employed to determine the changes in the protein expression profiles in SGC7901 cells in response to β-elemene treatment.</p><p><b>RESULTS</b>β-elemene significantly suppressed the cell viability and increased the apoptosis of SGC7901 cells, and these effects were less obvious in GES-1 cells. β-elemene decreased clonogenic survival of SGC7901 cells, increased the proportion of G2/M phase cells, decreased the expression of Bcl-2, and increased the expression of Bax and cleaved caspase-3. β-elemene did not obviously affect the expression of total p21-activated protein kinase 1 (Pak1) but decreased the level of phospho-Pak1 (Thr423) and phospho-ERK1/2 (Thr202/Tyr204) in SGC7901 cells.</p><p><b>CONCLUSION</b>β-elemene inhibits the proliferation and induces apoptosis of gastric cancer cells possibly by inhibiting Pak1/ERK signaling and regulating apoptosis-associated proteins such as Bcl-2 and Bax.</p>

ABSTRACT

Objective To investigate the effect of β-elemene on SGC7901 gastric cancer cell line and the potential proteins involved. Methods Human SGC7901 gastric cancer cells were treated with different concentrations ofβ-elemene.Cell viability was assessed.A proteomic method,isobaric tags for relative and absolute quantitation (iTRAQ),was employed to detect the proteins altered by β-elemene.Protein expression was validated by Western blot.Results β-elemene inhibited the viability of SGC7901 gastric cancer cells in a dose-dependent manner.Altogether,147 upregulated proteins and 86 downregulated proteins were identified in response to β-elemene treatment in SGC7901 gastric cancer cell line.Among them,the expressions of p21-activated protein kinase-interacting protein 1 (PAK1IP1 ),Bcl-2-associated transcription factor 1 (BTF)and topoisomerase 2-alpha (TOPIIα)were validated by Western blot and the trends were consistent with iTRAQ results.Top pathways involved inβ-elemene treatment in SGC7901 gastric cancer cell line included ribosome signaling,peroxisome proliferator-activated receptors (PPARs)signaling pathway,regulation of actin cytoskeleton,phagosome,biosynthesis and metabolism of some amino acids.Conclusion Our results suggest a promising therapeutic role of β-elemene for gastric cancer.The differentially expressed proteins give us better insights into the potential mechanisms involved in gastric cancer treatment using β-elemene.

ABSTRACT

Objective To explore the effects of obesity on the survival,growth and proliferation of gastric cancer and apoptosis by in vivo experiments so as to clarify the relationship between obesity and gastric cancer. Methods High fat diet-induced obese mice model was established.MFC cells were inoculated subcutaneously into mice to establish xenograft tumor model;then tumor growth and peritoneal metastasis were observed for 2 weeks. At the end of in vivo experiments,serum insulin and visfatin concentrations were assayed by ELISA,and blood glucose was determined by glucometer.MFC cell proliferation and apoptosis,as well as the number and size of adipocytes in xenograft tumor tissues were analyzed by immunohistochemistry, TUNEL and HE staining, respectively.Results High fat diet-induced obese mice model was successfully established within 12 weeks,and 66.7% of mice in the model were obese.Obese mice had distinct metabolic changes manifested as weight gain,high blood glucose,high serum visfatin,hyperinsulinemia and insulin resistance.All mice survived and developed no metastasis.The tumors from obese mice had a larger volume,heavier weight and greater intra-tumoral adipocytes, and exhibited higher proliferation and reduced apoptosis rate compared to those of non-obese and lean mice.Both serum insulin and visfatin concentrations correlated positively with tumor proliferation and negatively with tumor apoptosis.In addition,tumor weight showed a significantly positive correlation with mice body weight.Effects of diet-induced obesity on gastric cancer were not related to the influence of diet,but to the degree of obesity. Conclusion The altered adipocytokine milieu and insulin resistance observed in obesity may lead directly to alterations in tumor microenvironment,thereby promoting the survival and growth of gastric cancer.

ABSTRACT

<p><b>OBJECTIVE</b>To study radiation-enhancing effects on human gastric cancer MKN28 cell line and underlying mechanisms of β-elemene.</p><p><b>METHODS</b>Inhibition of MKN28 cell proliferation at different concentrations of β-elemene was assessed using the methyl thiazolyl blue colorimetric method (MTT method), with calculation of IC50 value and choice of 20% of the IC50 as the experimental drug concentration. Irradiation group and β-elemene+irradiation group were established, and the cell survival fraction (SF) was calculated from flat panel colony forming analysis, and fitted by the 'multitarget click mathematical model'. Draw the survival curve and get the radiobiological parameters D0, Dq, SF2, N and SER. Flow cytometry (FCM) was used to detect changes in the cell cycle and cell apoptosis rates was detected by Annexin-V/PI assay.</p><p><b>RESULTS</b>β-elemene exerted inhibitory effects on proliferation of gastric cancer MKN28 cells, with an IC50 of 45.6 mg/L and we chose 8 mg/L as the experimental concentration. The cell survival fraction of MKN28 cells with irradiation decreased significantly after treated with β-elemene; D0, Dq decreased, SER = 1.3. After combined treatment of β-elemene+irradiation, the results of FCM showed that cells could be arrested in the G2/M phase and the cell apoptosis increased significantly.</p><p><b>CONCLUSIONS</b>β-elemene can enhance the radiosensitivity of gastric cancer MKN28 cell line. Mechanistically, β-elemene mainly influences the cell cycle distribution of MKN28 cells by inducing G2/M phase arrest, inhibits the repair of sublethal damage and induces cell apoptosis to enhance the killing effects of radioactive rays.</p>

ABSTRACT

Objective To explore a new method for one-stage repair of the intestinal leakage based on the principle of magnetic compression anastomosis. Methods Twenty-four dogs were randomly divided into experimental group (n = 12) and control group (n = 12) according to random number table. The model of upper and multiple intestinal leakages was established by making transverse incisions of 1 cm in length on the jejunum wall about 50 cm and 100 cm away from the Treitz ligament. Forty-eight hours later, two NdFeB magnetic rings with the magnetic flux of 2500 G were put into the intestine from the leak sites. The leak sites were pressed between the two rings. The ventages in the control group were sutured. The condition of the dogs was observed after the repair of the leakage. The excreting time was recorded, and the leakage pressures of the anastomotic stoma were detected.The positions of the magnetic rings in the experimental group were detected by X ray. Tissues of the anastomotic stoma were processed by hematoxylin eosin and Masson staining. All data were analyzed using the two-sample t test. Results Severe abdominal infection occurred 48 hours after the establishment of the model. All the intestinal leakages in the experimental group were successfully repaired and the dogs survived for a long time. The magnetic rings were excreted six or seven days after the repair. Eight dogs of the control group survived. The leakage pressure of the anastomotic stoma seven days after the repair was (134 ±23)mm Hg (1 mm Hg =0. 133 kPa) in the experimental group and (91 ± 18)mm Hg in the control group, respectively, with a significant difference between the two groups (t = 3.225, P < 0.05). The leakage pressure of the anastomotic stoma 14 days after the repair was (281 ±7)mm Hg in the experimental group and (271 ±21) mm Hg in the control group, respectively, with no significant difference between the two groups (t =0. 988, P > 0.05). Histological observation showed that after the magnetic compression anastomosis, the intestinal muscle and mucosa recovered well, inflammatory reaction was slight and less collagen fiber and scar was formed. Conclusions Application of magnetic ring with the magnetic flux of 2500 G in one-stage repair of the intestinal leakage in the state of severe abdominal infection is safe and reliable.

ABSTRACT

Objective To compare the consistency of immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH) in detecting c-erbB-2 status in breast cancer tissues. Methods A total of 50 breast cancer paraffin embedded samples were selected, of which there were 10 cases of c-erbB-2 protein expression (+), 20 cases of (++) and 20 cases of (+++). FISH was used to assess the amplification of c-erbB-2 gene, and SPSS 13.0 software was employed to analyze the difference and consistency between the two methods. Results IHC and FISH methods had a good consistency when detecting c-erbB-2 (+) and (+++) expressions in breast cancer tissues, with the coincidence rate of 89.2%. However, when IHC was used to test c-erbB-2 (++), the result of FISH was quite different, with the coincidence rate of only 35.3%. Conclusion IHC is a preliminary method to detect c-erbB-2 status in breast cancer. IHC and FISH methods have a good consistency in detecting c-erbB-2 (+) and (+++) status in breast cancer tissues. As detection of c-erbB-2 (++) with IHC has a different result from FISH, such patients should receive FISH confirmation for herceptin therapy.

ABSTRACT

Objective To detect the expressions of proliferating cell nuclear antigen (PCNA), C-erbB-2, p53, estrogen receptor (ER) and progesterone receptor (PR) in order to explore the proper margin for breast conservative surgery on Chinese women. Methods We collected 40 resection specimens from breast cancer patients who had received radical surgery. Then we divided each specimen into primary tumor group and hyperplasia and gene expression characteristics of PCNA, c-erbB-2, p53, ER and PR were measured by pathological and immunohistochemical assay in the five groups. Results With the further distance from the primary tumor, the proportions of high-risk disease and positive gene expressions of PCNA, c-erbB-2 and p53 in paracarcinoma tissues gradually decreased (P<0.05). Higher risk and more positive expressions were related to paracarcinoma was no correlation of PCNA, ER and PR expressions adjacent to breast cancer with tissue differentiation and lymph node metastasis (P>0.05). a safe and appropriater region for breast conservative surgery.

ABSTRACT

Objective To compare and evaluate the efficacy of diagnosis and excision for appropriately selected breast multi-focal lesions and solitary lesion by ultrasound-guided vacuum-assisted biopsy (UGVAB). Methods Among 392 appropriately selected patients, 187 patients with multi-focal lesions and 205 patients with solitary lesion were treated by the 8-gauge UGVAB from May 2007 to June 2009. All lesions were removed as completely as possible. The patients with benign pathology underwent physical and ultrasound examinations at one week and 6 months after procedure. Results During the procedure, only three patients had vasovagal syncope and twenty others complained of other intraoperative discomfort. An accurate pathological diagnosis was obtained in all lesions. There was no apparent false-negative result among the 696 lesions with benign pathology at a follow-up of 6 months after procedure. The rates of malignant or premalignant pathology, postoperative complications and residual lesions in patients with multi-focal lesions were higher than those in patients with solitary lesion. If each lesion was considered as a subject of study, there was no significant difference between the two groups. Conclusion UGVAB is an effective method for diagnosis and excision of appropriately selected breast multi-focal lesions and can be used routinely.

ABSTRACT

Objective To investigate the effects of low dosage of β-elemene on the radiosensitivity of rabbit VX2 renal transplant carcinoma model. Methods We took the rabbit VX2 renal transplant carcinoma as the model. Experimental rabbits were divided into three groups: the control group, the radiation group, and the radiation +β-elemene (radiosensitivity) group. The change of tumor was observed by Spiral CT and B ultrasound to compare its regrowth period. The tumor was measured by light microscopy and electron microscopy. Results The tumor in radiosensitivity group was restrained obviously and the sensitization enhancement ratio (SER) of β-elemene was 1.89. Different apoptosis was observed under transmission electron microscopy. Conclusion Low dosage β-elemene can enhance the radiosensitivity of rabbit VX2 renal transplant carcinoma model and induce the apoptosis of tumor cells, but the mechanism needs further study. It promotes apoptosis in mechanisms in vitro.

ABSTRACT

OBJECTIVE: To investigate the radiosensitization of beta-elemene on VX2 carcinoma transplanted on kidney in rabbits in vivo. METHODS: The rabbits were all transplanted with VX2 carcinoma on kidney. The appropriate dose of beta-elemene infusion via renal artery for further study on radiosensitization was determined. Then fifty-five rabbits were divided into three groups: untreated group, radiation group and radiation plus beta-elemene-treated group. After corresponding intervention for each group, the tumor volume was measured by ultrasonography and spiral computed tomography. The sensitization enhancement ratio (SER) of beta-elemene was calculated. The pathological change of tumor tissue in kidney was observed by light microscopy and electron transmission microscopy. The apoptotic index was also examined by TdT-mediated dUTP-biotin nick end labeling method. RESULTS: The most significant radiosensitivity was observed in the radiation plus beta-elemene-treated group with 6 Mev X-ray radiation dose of 3 Gy.Fx(-1).d(-1) x 5 d and beta-elemene dose of 10 mg.kg(-1).d(-1). The average time delayed for tumor growth was obviously longer in the radiation plus beta-elemene-treated group than those in the untreated group and radiation group. The SER of beta-elemene was 1.89. The apoptotic index of tumor cells in the radiation plus beta-elemene-treated group was also significantly higher than those in the untreated group and radiation group. CONCLUSION: The beta-elemene can enhance the effects of irradiation on VX2 carcinoma transplanted to kidney in rabbits in vivo by inducing apoptosis of tumor cells.

ABSTRACT

OBJECTIVE: To investigate the curative effect and mechanism of beta-elemene interventional treatment on VX2 carcinoma transplanted on kidney in rabbits. METHODS: The rabbits were all transplanted with VX2 carcinoma on kidney. Fifty-five rabbits were randomly divided into 11 groups. Rabbits in these groups were administered interventional treatment of normal saline, iodinated oil, mitomycin, 5-fluorouracil, beta-elemene, cisplatin, carboplatin, adriamycin, thiotepa, cyclophopsphamide, and vincristine, respectively. After corresponding intervention, the tumor volume in each group was measured by ultrasonography and spiral computed tomography, and the tumor growth rate (TGR) was calculated. Nenal and hepatic functions of the rabbits in each group were compared 1 day, 7 and 14 days after the interventional treatment. Morphologic change of the tumor was observed by a light microscopy and a transmission electron microscopy 14 days after interventional treatment. The expressions of Bax and Bcl-2 were measured by immunohistochemical straining. RESULTS: There was statistical significance in the effects of different medicines intervened on VX2 kidney transplanted carcinoma. The VX2 carcinoma of rabbits had high-sensitivity to iodized oil embolism, mitomycin, cisplatin and carboplatin, which showed serious damage to the kidney function, medium-sensitivity to beta-elemene, adriamycin and 5-fluorouracil, in which beta-elemene showed slight damage to the kidney function, and resistance to thiotepa, cyclohosphamide and vincristine. Most tumor cells displayed apoptosis in the beta-elemene interventional treatment group under light microscopy and transmission electron microscopy, and only few tumor cells displayed necrosis. The Bax expression was up-regulated (P0.05) in the beta-elemene interventional treatment group. CONCLUSION: Intervention treatment of beta-elemene has significant effect on VX2 kidney transplanted carcinoma and little side effect on the kidney function. Its mechanism is related to enhancing the apoptosis of tumor cells, and Bax gene participates in this action.
