STGC3, a novel tumor related gene, was cloned recently. The previous studies indicated that STGC3 can inhibit the proliferation of CNE2 cell line in vitro. To examine the effect of STGC3 on the tumorigenicity of CNE2 cell line and explore its mechanism in nude mice. The Tet/pTRE/CNE2-STGC3 cell line was planted under the front leg skin of nude mice and induced by doxycycline (Dox). The mRNA and protein level of STGC3 in transplanted tumor tissues were detected with RT-PCR and Western Blotting. The apoptosis ratio of the tumor cell was analyzed with flow cytometry. STGC3, Bcl-2 and Bax proteins were examined by immunohistochemistry method. The results indicated that high level of STGC3 expression can inhibit tumorigenicity of CNE2 cell line in nude mice. Tumor grew slowly, later and smaller. Cell apoptotic percentage increased. Bcl-2 protein expression was down-regulated and Bax protein expression was up-regulated in Tet/pTRE/CNE2-STGC3 cell line (P

Objective To study the clinical significance for expression of serum matrix metalloproteinase and HER-2 extracellular domain in primary breast cancer.Methods Two hundred and forty two early breast cancer patients were enrolled as research group who met the criteria in Peking University Shenzhen Hospital from May 2015 to October 2017.They were divided into HER-2 positive breast cancer group (n =53) and HER-2 negative breast cancer group (n =189) according to HER-2 status.At the came time,non breast cancer women were recruited in outpatient as control group.The concentrations of serum MMP-2,MMP-9 and HER-2 ECD were detected by ELISA,and the differences of concentration in each grup were compared.Measurement data were expressed by mean and standard deviation,t test was used between two groups of parameters.A single factor analysis of variance was used among the multiple groups of parameters,and LSD test was used in the comparison between every two groups.Results The serum levels of MMP-2,MMP-9 and HER-2 ECD were (12.07 ± 1.23) ng/ml,(25.20 ±3.53) ng/ml and (10.42 ± 6.08) ng/ml in research group,HER-2 positive group were (13.43 ± 4.63) ng/ml,(25.24 ± 2.12) ng/ml and (13.25 ± 3.42) ng/ml,HER-2 negative group were (10.55 ± 3.72) ng/ml,(23.16 ±3.21) ng/ml and (6.33 ±4.11) ng/ml.The serum levels of MMP-2,MMP-9 and HER-2 ECD in the control group were (9.03 ± 1.15) ng/ml,(21.15 ±2.12) ng/ml and (4.71 ± 1.93) ng/ml.There were significant differences in MMP-2,MMP-9 and HER-2 ECD concentration between research group and control group (all P ＜ 0.0001).There was significant difference between HER-2 positive group and HER-2 negative group,HER-2 positive group and control group in the HER-2 ECD (P ＜ 0.0001).There were significant difference between control group and HER-2 positive group,control group and HER-2 negative group in the MMP-2 and MMP-9(P ＜ 0.000 1).In the HER-2 positive group,there was significant difference between HER-2 ECD positive and HER-2 ECD negative subgroup of MMP-2 and MMP-9(P ＜ 0.000 1).Conclusions In early breast cancer,HER-2 positive is an important condition for HER-2 ECD positive,and associated with abnormal activation of MMP.Combined detection of serum HER-2 ECD,MMP-2 and MMP-9 contributes to the determination of HER-2 status in tissues.

Objective:To explore the application effect of ultrasound-guided pectoralis Ⅱ(PECS-Ⅱ)blocks anesthesia in benign tumor resection of breast.Methods:A total of 60 female patients who underwent benign tumor resection of breast were selected from Maternity and Child Care Center of Qinhuangdao from January 2021 to December 2021,and they were divided into the thoracic nerve block group(nerve block group)and local infiltration anesthesia group(local anesthesia group)according to the random number table method.The nerve block group used ultrasound-guided PECS-Ⅱ anesthesia,and the local anesthesia group used local infiltration anesthesia for tumor.The hemodynamic indicators,postoperative visual analogue score,first intervention time of postoperative analgesic drugs,and the use of sufentanil within 24 hours after surgery were compared and analyzed between the two groups of patients.Results:The average operation time of the nerve block group was(127.32±34.56)min,and the difference of that between the nerve block group and local anesthesia group(128.11±33.84)min was no statistically significant(P>0.05).The differences of the heart rate(HR)and mean arterial pressure(MAP)before anesthesia(T0)between two groups of patients were not statistically significant(P>0.05).The HR and MAP levels at the time of skin incision(T1),at the 0.5 h after the surgery was conducted(T2)and the time of completing surgery(T3)in nerve block group were significantly lower than those of the local anesthesia group,respectively.The differences were statistically significant(tHR=5.709,5.836,5.662,tMAP=3.501,3.223,3.128,P<0.05),respectively.Compared with the local anesthesia group,the pain level at the same time point in the nerve block group was significantly reduced,and the difference was statistically significant(t=4.501,6.575,8.197,8.262,P<0.05),respectively.The intervention time of analgesic medication at the first time of the nerve block group was significantly later than that of the local anesthesia group,and the consumption of sufentanil within 24 hours after surgery of the nerve block group was also significantly reduced,and the differences of them were statistically significant(t=13.741,9.482,P<0.05),respectively.Conclusion:Ultrasound-guided PECS-Ⅱ can effectively relieve postoperatively early pain in patients with benign tumors of breast,and delay the intervention time of postoperative analgesic medication,and reduce the intake amount of opioid drugs.

China has entered a period of high incidence of colorectal cancer. The year of 2015 is the start of precision medicine. Colorectal cancer "precision medicine" is based on the analysis of the cancer genome sequencing and information analysis, interprets the mechanism of the occurrence, development, invasion, metastasis and recurrence of colorectal cancer, and helps to implement targeted individual treatment. The experts of the world's Colorectal Cancer Subtyping Consortium, integrated the past genetic testing based on the classification of colorectal cancer subtypes, refered to the indices of gene mutation, copy number, methylation, microRNA and proteomics, and coalesce the types of colorectal cancer into four consensus molecular subtypes(CMSs) with distinguishing features. CMSs may be the most powerful classification system of colorectal cancer because of its clear biological interpretation, and is expected to provide a reference basis for the establishment of clinical precision treatment system.

OBJECTIVETo explored the relationship of clinicopathological classification and clinical and pathological characteristics of breast cancer and analyze the value in treatment.

METHODSThe patients with invasive breast carcinoma had been treated between January 2011 and December 2012. The breast cancer have been divided into luminal A, luminal B, HER2-positive and triple-negative subtypes according to criteria of St. Gallen International Expert Consensus report 2011. The Mann-Whitney test and Kruskal-Wallis test were used to analyze the relationships between four subtypes and TNM staging, histopathological grading.

RESULTSThe 530 cases of invasive breast cancer patients were included in this study. The luminal A was 94 cases (17.7%), the luminal B was of 285 cases (53.8%), the HER2-positive was 59 cases (11.1%), and the triple-negative subtype was 92 cases (17.4%). In luminal B subtype, the HER2-positive was 56 (19.6%) and negative was 229 (80.4%). Most of luminal B was later in grade (71.7% of cases were more than II grade) and stage (66.7% were more than stage II).

CONCLUSIONSClinical pathological classification is important in the individualized treatments of breast cancer, and the Luminal types (A+B) are more than 71.5% of all breast cancer patients, and they should be paid more attention to the endocrine therapy; Luminal B type accounted for 53.8% of all breast cancer and it needs further study to improve the precision of the diagnosis and treatment.

Objective: To investigate the use of conventional MR imaging to guide treatment in patients with cholecystolithiasis and diffuse inflammatory thickening of gallbladder wall. Methods: The clinical data of patients who were treated in the Ningbo Huamei Hospital, University of the Chinese Academy of Sciences between January 2017 and January 2018 were analyzed. These patients were divided into two groups: patients with acute cholecystitis (n=139) and patients with viral hepatitis combined with cholecystolithiasis (n=67). Differences in the imaging signs in standardized upper abdominal contrast enhanced MRI examinations were retrospectively analyzed. Results: The imaging signs, including stone location, continuity of gallbladder mucosa, exudation in peri-gallbladder space, edema of intrahepatic portal area showed significant differences between the two groups (all P<0.05). On stratification analysis, the type of thickened gallbladder wall, background of liver parenchyma and extent of edema in intrahepatic catchment area also showed significant differences (all P<0.05). The imaging signs, including non-gallbladder neck ductal stones, concentric thickening of gallbladder wall, continuous mucous membrane in gallbladder and no peri-gallbladder space exudation but diffuse edema of intrahepatic catchment area supported the diagnosis of viral hepatitis combined with gallstones. The imaging signs, including discontinuity of gallbladder mucosa, exudation of peri-gallbladder space, diffuse edema of gallbladder wall without a cirrhotic background and edema in intrahepatic portal area supported the diagnosis of acute calculous cholecystitis of gallbladder. Conclusions Routine upper abdominal contrast enhanced MRI plays an important role in demonstrating the underlying cause of gallbladder wall diffuse edema thickening in patients with gallstones. It provides an important reference for the choice of clinical treatment pathway.
