Objective To investigate the association of Her-2 protein expression and gene expression in gastric cancer by different methods,and to explore the effective approaches of Her-2 in gastric cancer detection.Methods Immunohistochemistry (IHC) was used to mark Her-2 protein in 68 cases of gastric cancer,and fluorescence in situ hybridization(FISH)wasused to detect the Her-2 gene amplification.Results Among 68 cases,IHC Her-2 protein in 12 cases(17.65 ％)was positive expression,including ++ 3 cases ++ 9 cases,+ 7 cases and-49 cases.By FISH,Her-2 gene in 11 cases(16.17 ％)was overexpression.Corresponding to the IHC results,FISH results was 3 cases(100 ％),8 cases(88.89 ％),0 cases,0 cases,respectively.Conclusion Her-2 protein expression and gene overexpression occur in gastric cancer.Her-2 protein expression in gastric cancer shows significant heterogeneity.Her-2 gene overexpression and Her-2 protein expression is correlated (P＜0.05).The differences of Her-2 expression in gastric cancer by IHC and FISH mostly occur in IHC++ groupe.Suggestion of Her-2 gene test should be given for patients with IHC++ who will be undertaken Her-2 gene therapy.

Objective To assess the diagnostic value of magnetic source imaging(MSI) in the preoperative localization of focal cortical dysplasia(FCD). Methods Eighty-two patients with intractable epilepsy resulting from FCD undergone preoperative assessment including MSI, video electroencephalography(VEEG) and electrocorticography(ECoG)from February 2006 to June 2012.The consistency between pre- and intra-surgical assessment was evaluated. For patients who had consistent results,postoperative curative effect was also recorded. The accuracy and predictive values of noninvasive preoperative tests were compared by χ2 test. Results For MSI and ECoG, their results were consistent in 57 cases, partially consistent in 14 cases, and inconsistent in 11 cases. In the postoperative follow-up of 57 patients with consistent results, there were 46 cases with Engel class Ⅰ, 3 cases with Engel class Ⅱ, 4 cases with Engel class Ⅲ, and 4 cases with Engel class IV. For VEEG and ECoG, the results were consistent in 43 cases, partially consistent in 33 cases, inconsistent in 6 cases.The postoperative follow-up showed that 27 cases were graded as Engel classⅠ, 5 cases as Engel classⅡ,7 cases as Engel classⅢ, and 4 cases as Engel class IV. There were statistically significant differences(χ2=5.023,P=0.025)of the concordance rate with ECoG between MSI(69.51%,57/82)and VEEG(52.44%,43/82). In the postoperative follow-up of patients with consistent results, the curative effect was better in group MSI than in group VEEG (χ2=3.989,P=0.046). Conclusions Preoperativelocalization by MSI shows advantage over VEEG, which meanswhen it achieves an agreement with ECoG, patients with FCD may get better prognosis from the surgical process.

Immunohistochemistry was used to detect the protein expression of Snail in 5 specimens jusxta-eancerous normal breast tissues, 35 specimens of cancerous tissues without metastasis and 20 specimens of breast carcinoma with lymphonode metastasis. Breast carcinoma cell line MDA-MB-231 was transfected with antisense Snail. Results showed that the expression of Snail protein was significantly higher in breast carcinomas than in their normal tissues. The mRNA and protein expressions of Snail in the breast carcinoma cells treated with antisense Snail was significantly decreased while the E-cadherin protein significantly increased (both P < 0.05). The number of invasive ceils treated with antisense Snail was (10.5±1.3)%, while in treated with EGFP was (68.2±2.1)% (P < 0.05). The abnormal expression of Snail contribute to the invasiveness of breast carcinoma. The antisense Snail could prevent the cells ability to invade in vitro, and the effect is related with the up-regulated E-cadherin protein.

Objective:To evaluate the clinical efficacy of thermal-therapy combined with 125 I radioactive particles by comparing the results of preoperative and postoperative images,serum carcino-embryonic antigen (CEA) and following-up after treatment of the patients with recurrent rectal cancer.Methods:Nineteen rectal cancer patients with postoperative recurrence after radiotherapy were treated with 125I implantation guided by CT (20 cases were treated with operation,but 1 patient was exited who couldn't tolerate the thermal-therapy).Radioactive particle treatment planning system (TPS) was used to make the plan before the particle implantation,and the distance of the particle was 1.0 cm;all patients received CT scanning and were quantificationally evaluatated after implantation;the number of seeded particles was about 12-58,the radioactivity of the 125I particle was 0.5 mCi,and the matching dose surrounding the tumor was 90-140 Gy.All patients were treated with microwave thermal-therapy after particle implantation,60 min per time,lasting the temprature at 43℃,twice per week,for three weeks.And the patients were followed up after treatment for 3 months,the efficacy was evaluated by image and CEA results,and the urinary frequency,dysuria,hematuria and rectal bleeding were evaluated.Results:Compred with before treatment,after following up for 6 months,the image results showed that the tumor volume was reduced,and the blood CEA level of all patients were decreased from (30.25±8.32) mg · L-1 to (11.89±5.22) mg · L-1 (t=13.158,P＜0.01);the local efficacy was 94.7％ (18/19),and the pain relief rate was 94.4％ (17/18);the NRS median was 6 (4,7) before treatment,and it was 1 (0,3) after treatment,there was significant difference (P＜0.001).There were no frequent urination,urinary pain,hematuria,rectal bleeding and other complications in all patients.Conclusion:Thermal-therapy combined with 125I radioactive particle implantation has good curative effects on the recurrent rectum cancer,and is effective means for recurrent rectum cancer treatment.

Objective To discuss the BRAF V600E mutation rate in papillary thyroid carcinoma (PTC) and its relationship with the clinicopathological features. Methods Two hundred and sixty-five PTC patients(including 226 cases of classical type,29 cases of follicular type, 3 cases of high cell type, 2 cases of diffuse sclerosis type, 2 cases of eosinophilic type, 3 cases of cystic type) from August 2014 to October in Shanxi Provincial Cancer Hospital, were collected with completely clinical and pathological information. The BRAF V600E mutation was detected by real-time polymerase chain reaction (RT-PCR) method. Pearson χ 2 test and the exact probability method were used to analysis the relationship between gene mutations and clinicopathological data. Results BRAF V600E mutation rate in PTC patients was 73.21 %(194/265). There was no significant difference in the mutation rate of BRAF V600E among patients with different age, gender, tumor location,tumor number and extravaginal invasion(all P>0.05),but the mutation rates of BRAF V600E gene in patients with different tumor size, histopathological subtypes, lymph node metastasis and clinical stage were significantly different(all P<0.05).Conclusion The PTC patients with positive BRAF V600E mutation have poor clinicopathological features,and BRAF V600E mutation may be a predictor of advanced PTC.

Objective:To investigate the correlation between KRAS, NRAS and BRAF V600E gene mutations and the clinicopathological characteristics of patients with colorectal cancer.Methods:Specimens from 217 patients with colorectal cancer who underwent surgical resection and were pathologically confirmed in Shanxi Province Cancer Hospital from January 2020 to December 2021 were selected, and the clinical data of the patients were retrospectively analyzed. The mutation status of KRAS, NRAS and BRAF V600E genes were detected in the paraffin specimens of surgically-resected tissues by direct sequencing. The mutation rates of KRAS, NRAS and BRAF V600E were compared among patients with different clinicopathological characteristics.Results:The mutation rates of KRAS, NRAS and BRAF V600E in 217 patients with colorectal cancer were 48.4% (105/217), 4.1% (9/217) and 3.7% (8/217), of which 1 patient (0.5%) had both KRAS and NRAS mutations. NRAS gene mutation was not correlated with gender, age, tumor size, tumor location, pathological type, degree of differentiation, depth of invasion, lymph node metastasis, distant metastasis, TNM stage, hemangioma thrombus/nerve invasion (all P>0.05); KRAS mutation rate in patients ≥ 60 year old was higher than that in patients < 60 year old [55.3% (63/114) vs. 40.8% (42/103), χ2 = 4.55, P = 0.033),and there was no correlation between KRAS gene mutation and other clinicopathological features (all P > 0.05); the mutation rate of BRAF V600E gene in colorectal cancerpatients with distant metastasis was higher than that in patients without distant metastasis [16.7% (4/24) vs. 2.1% (4/193), P = 0.006], and there was no correlation between BRAF V600E gene mutation and other clinicopathological features (all P > 0.05). Conclusions:Older colorectal cancer patients may be prone to KRAS gene mutation, and the BRAF V600E gene mutation rate is higher in patients with distant metastasis, and there is no correlation between NRAS gene mutation and clinicopathological characteristics.

Objective: “Food addiction” may be one of the drivers of the obesity epidemic. Bariatric surgery-induced weight loss can significantly alleviate food addiction in overweight or obese people. Appetite regulation is part of the feedback control system for energy balance. The purpose of this study was to investigate the effects of mobile application-based dietary intervention on weight-loss and food addiction in overweight and obese adults. Methods: A total of 101 overweight or obese people aged over 18 years, who were admitted to the obese multidisciplinary clinic of Ningbo First Hospital from August 2015 to January 2018 were enrolled. All subjects received health education and dietary guidance, and submitted their diet log through the weight management application of their smartphone. Over 12 weeks, a dietitian guided and corrected the subjects who did not meet the diet standards. Interviews, physical examinations, laboratory tests, and the Yale Food Addiction Scale Questionnaire survey were administered before and after the intervention (12 weeks) comparing subjects’ weight, food addiction symptom count, and the proportion of food addiction before and after intervention. Statistical analysis of body composition measurements, blood biochemical parameters, and symptom count scores was performed using paired data t-test, McNemar chi-square test, and Fisher’s exact test. Results: A total of 101 overweight and obese subjects were enrolled, including 31 males and 70 females, with an average age of (30.4±7.3) years, mean body mass index of (32.76±4.46) kg/m², and average body weight of (89.95±17.12) kg. The proportion of food addiction was 26.73%. After 12 weeks of dietary intervention with the mobile application, the number of people with food addiction decreased from 27 to 14, the proportion of food addiction decreased by 12.87%, the proportion of symptom counts ≥3 decreased from 41.58% to 19.80%.（χ²=5.17， 11.26, all P <0.01), and the symptom count decreased from 2.25 ±1.61 to 1.50±1.31 (t=3.64, P<0.001). Simultaneously, body weight, BMI, and waist circumference decreased by (6.54±1.03) kg, (2.35±0.36) kg/m², and (6.50±0.86) cm (t=6.36, 5.62 and 3.78, all P<0.001), respectively, compared with those before the intervention. Metabolic indicators such as fasting glucose, insulin resistance index, and LDL-C cholesterol also significantly improved, with a decrease of (0.38±0.10) mmol/L, 1.83±0.46, (0.22±0.75) mmol/L (t=3.67, 3.59, 2.97, all P<0.01). Conclusion The smartphone application-based dietary intervention can effectively improve blood glucose and lipid levels in overweight and obese people, reduce visceral fat accumulation and reduce insulin resistance, and improve the food addiction status of overweight and obese people.

Objective    To evaluate the clinical outcomes of larynx-preserving limited resection with total thoracic esophagectomy and gastric pull-up reconstruction for the treatment of cervical esophageal squamous cell carcinoma (ESCC) without tumor involvement of the larynx and hypopharynx compared with the upper thoracic ESCC. Methods    Retrospective and comparative analysis of consecutive patients with cervical and upper thoracic ESCC who underwent R0 surgical resection from 2006 to 2011 in our center was performed. Kaplan-Meier method was used to calculate the patients’ survival. Results    In total, 44 pairs of patients, including 71 males and 17 females with an average age of 60.66±8.49 years were enrolled in the study after propensity score matching. The baseline characteristics of the two groups of patients were well balanced. There was no statistical difference in the operation time (P=0.100), blood loss (P=0.685), mortality rate in 30 days (P=1.000), total complication rate (P=0.829), cervical anastomosis leakage (P=0.816), mechanical ventilation (P=1.000), normal oral diet within 15 days (P=0.822) and anastomosis recurrence rate (P=0.676) between the two groups. Survival analysis showed that there was no statistical difference in survival time between the cervical group [31.83 (95%CI 8.65-55.02) months] and upper thoracic group [37.73 (95%CI 25.29-50.18) months, P=0.533]. The 5-year survival rates were 32.6% and 42.1%, respectively. Conclusion    Larynx-preserving limited resection  with total thoracic esophagectomy and gastric pull-up reconstruction for the treatment of cervical ESCC without involvement of the larynx and hypopharynx may result in a similar clinical outcome to upper thoracic ESCC.
