ObjectiveTo study value of long noncoding RNA H19 and HOTTIP in plasma in predicting efficacy of neoadjuvant chemotherapy (NAC) for resectable locally advanced gastric cancer. MethodsForty patients with T3–4aN+M0 gastric cancer and 40 patients with benign gastric diseases treated in the Yantai Yuhuangding Hospital Affiliated to Qingdao University from August 2020 to May 2021 were prospectively included. The expressions of H19 and HOTTIP in the plasma of gastric cancer and benign gastric diseases patients without any treatment after admission were detected before treatment (CAPEOX regimen was used in the patients with gastric cancer), then which were detected after 2 NAC courses for patients with gastric cancer. Meanwhile, some clinical items were detected and the efficacy of NAC was evaluated. The complete remission (CR) and partial remission (PR) were classified as objective remission, CR, PR, and disease stability were classified as disease control. The expressions of H19 and HOTTIP between the different patients were compared and the receiver operating characteristic (ROC) curve was used to evaluate their values in the diagnosis of resectable locally advanced gastric cancer. ResultsThere were 13 cases of T downstaging and 27 cases of T non-downstaging and 25 cases of objective remission and 35 disease control after NAC. The median relative expression levels of H19 and HOTTIP before NAC in the patients with gastric cancer were higher than those in the patients with benign gastric diseases (H19: 1.42 versus 0.98, Z=–3.835, P<0.001; HOTTIP: 2.15 versus 1.04, Z=–5.062, P<0.001), and which were in the patients with T downstaging and disease control were lower than those in the patients with T non-downstaging and 5 cases of disease progression (For T staging, H19: 1.12 versus 1.54, Z=–2.960, P=0.002; HOTTIP: 1.49 versus 2.30, Z=–2.310, P=0.019. For efficacy of NAC, H19: 1.39 versus 2.48, Z=–3.211, P<0.001; HOTTIP: 1.96 versus 3.25, Z=–2.393, P=0.014). The median relative expressions of H19 and HOTTIP after NAC were lower than those before NAC in the patients with gastric cancer (H19: 1.12 versus 1.42, Z=–3.965, P<0.001; HOTTIP: 1.30 versus 2.15, Z=–4.839, P<0.001). There were no significant differences in the changes of H19 and HOTTIP before and after NAC between the patients with T downstaging and T non-downstaging, and between disease control and disease progression (P>0.05). The areas of ROC curve of H19, HOTTIP, and combination of H19 and HOTTIP in diagnosis of resectable locally advanced gastric cancer were higher than 0.7. ConclusionsLncRNA H19 and HOTTIP might be potential tumor markers in gastric cancer, and their diagnostic values for resectable locally advanced gastric cancer are higher. Gastric cancer patients with low expressions of H19 and HOTTIP in plasma might be more sensitive to NAC.

ObjectiveTo study on the first metastasis pattern and prognostic factors in patients with recurrent and metastatic breast cancer.MethodsThe study selected 147 patients with metastatic breast cancer who were diagnosed for the first time in the Breast Thyroid Center and Oncology Department, the People's Hospital of Wuhan University from June 2016 to June 2018. The model of first metastasis and the first diagnosis of prognosis may be affected. The age at diagnosis of breast cancer, tumor size, lymph node metastasis, hormone receptor status, HER-2 status, number of metastatic organs, tumor location, molecular typing, etc. were retrospective analyzedResultsThe most common metastatic sites for breast cancer was bone metastases in 55 patients (37.41%), followed by lung metastasis and liver metastases, 29 (19.73%) and 24 (16.33%), respectively. Univariate analysis showed that the number of lymph node metastasis, HER-2 status, organ number of first-time metastasis, and endocrine therapy were significant factors affecting metastatic survival time, and the difference was statistically significant (P<0.05). Multivariate analysis showed that the number of lymph node metastasis, the number of metastatic organs and HER-2 were independent risk factors for advanced breast cancer (P<0.05).ConclusionsThe most common metastasis of breast cancer patients after surgery is bone, followed by lung metastasis and liver metastasis. The number of lymph node metastases, the number of metastatic organs, HER-2 status, and endocrine therapy are independent factors influencing the prognosis of patients with recurrent metastasis.

Objective
To explore value of multidisciplinary team (MDT) model in diagnosis and treatment of patients with advanced special thyroid cancer who lost chance of operation.
Method
Two patients with the advanced special thyroid cancer who lost chance of operation were treated by low dose apatinib (250 mg/d) after the MDT discussion.
Results
One medullary thyroid cancer patient with the compressing of the trachea for mediastinal metastatic lymphadenopathy and inability to lie down underwent the multiple surgical treatment, the therapeutic effect was poor. Then low dose apatinib (250 mg/d) was performed, the patient could supine, breathe smoothly, and move freely, whose life quality was obviously improved, the mediastinal lymph nodes reduced and no serious drug toxicity occurred on month 1 after the treatment. One undifferentiated thyroid cancer patient with the lung metastasis, hemoptysis, and tumor invasion resulted in the inability to lie down and having difficulty in breathing, these symptoms still existed and more pleural effusion occurred after the resection of the invaded trachea. Then low dose apatinib (250 mg/d) was performed, the patient could supine, the pleural effusion disappeared, the hemoptysis stopped, the breathing was smooth, and could do some minor housework, no drug toxicity occurred on month 1 after the treatment.
Conclusion
After MDT discussion, low dose apatinib in treatment of advanced special thyroid cancer is reliable and safe and has a good short-term effect, which could be used as a new remedy, but long-term effect should be further researched by increasing case samples and a long-term following-up.
ObjectiveTo recognize the latest research progress of immunotherapy for advanced gastric cancer (AGC). MethodThe domestic and international literature on immunotherapy for AGC in recent years were retrieved and reviewed. ResultsThe immunotherapy for AGC mainly focused on immune checkpoint inhibitors (ICIs), cellular immunity, and antitumor vaccines. The most immunotherapy researched was ICIs, especially for programmed death protein-1 / programmed death protein ligand 1, cytotoxic T lymphocyte associated antigen 4, and lymphocyte activating gene 3. The cellular immunotherapy and tumor vaccine therapy were less relatively. Although immunotherapy alone did not have a particularly good effect, its therapeutic effect was not inferior to that of chemotherapy alone and the incidence of adverse reactions was lower. Moreover, most studies had concluded that the use of immunotherapy in combination with other therapy had shown a good clinical efficacy, especially in combination with anti-human epidermal growth factor receptor 2 antibody, and chimeric antigen receptor T cells targeting Claudin 18.2 site had promising results in the AGC. ConclusionsWith the development of immunotherapy research, the strategies of immunotherapy for AGC are also constantly improving. Precision medicine is important in the process of immunotherapy. Targeted screening suitable patients and adopting precise treatment can further benefit the survival of patients with AGC.
ObjectiveTo compare clinical efficacy of 4 kinds of surgical treatment for high transsphincter fistula.
MethodsThe clinical data of 116 patients with high transsphincter fistula in Jiangsu Province Hospital of TCM from January 2012 to December 2014 were analyzed retrospectively.These patients were divided into 4 groups according to surgical treatments,including cut seton group (n=30),loose seton group (n=34),ligation of intersphincteric fistula tract group (LIFT,n=41),mucosa advancement flap group (MAF,n=11).The length of stay,incision healing time,postoperative pain score on the second day,Wexner score when healed,postoperative complications,curative status,and recurrence were observed.
Results① The length of stay in the loose seton group was significantly longer than that in the LIFT group (P<0.01),cut seton group (P<0.05) or MAF group (P<0.05),but which had no differences among the other groups (P>0.05).② The incision healing time in the loose seton group was significantly longer than that in the LIFT group (P<0.01) or the MAF group (P<0.05),but which had no differences among the other groups (P>0.05).③ The postoperative pain score on the second day in the cut seton group was significantly higher than that in the other three groups (P<0.01),which in the MAF group was lower than that in the LIFT group (P<0.05),but which had no difference between the other groups (P>0.05).④The Wexner score when healed in the cut seton group was significantly higher than that in the other three groups (P<0.01),bwt which had no differences among the other groups (P>0.05).⑤ The rate of postoperative complica-tion in the LIFT group was significantly higher than that in the loose seton group (P<0.05),but which had no differences among the other groups (P>0.05).⑥ The curative rate and recurrence rate had no statistically differences among the 4 groups (P>0.05).
ConclusionsCurative rate and recurrence rate in loose seton,LIFT,and MAF group are similar with cut seton group,meanwhile they could protect anal function better and relieve pain.The length of stay and the incision healing time are longer in the loose seton group.The postoperative complications in LIFT group is increased as compared with loose seton group.The postoperative pain of MAF group is slighter than that in LIFT group.Comprehensive evaluation,MAF has more advantages,but the technique is more complex.The decision should be made individually according to patients and surgeons.
ObjectiveTo analyze the factors influencing the total number of harvested lymph nodes in laparoscopic radical gastrectomy for advanced gastric cancer.MethodsThe clinicopathologic data of patients who underwent laparoscopic D2 radical resection of gastric cancer in this hospital for advanced gastric cancer from January 2018 to July 2020 were retrospectively analyzed. The statistical analysis was conducted to analyze the influence factors (age, gender, tumor size, tumor site, body mass index, infiltration depth, lymph node metastasis, HER-2 gene amplification status, presence or absence of vascular tumor thrombus, presence or absence of nerve infiltration, differentiation type, pTNM, Borrmann type, and type of gastrectomy) on the number of harvested lymph nodes.ResultsA total of 536 patients met the inclusion and exclusion criteria were included. The results of univariate analysis showed that the total number of harvested lymph nodes during laparoscopic radical gastrectomy for advanced gastric cancer was correlated with age, tumor size, tumor infiltration depth, lymph node metastasis, pTNM stage, Borrmann type, and type of gastrectomy. That was, the younger the patient was (≤ 54 years old), the larger the tumor was (long diameter >3.5 cm), the later the Borrmann classification was (type Ⅲ, Ⅳ), the deeper the tumor invasion was, the more the number of lymph node metastasis was, the later the pTNM stage was, and the more the number of lymph nodes was detected in patients undergoing total gastrectomy (all P<0.05). The multiple linear regression analysis showed that the age, lymph node metastasis, and PTNM stage had significant effects on the number of harvested lymph nodes. The multiple linear regression model was statistically significant (F=6.754, P<0.001). 11.2% of the variation in the number of harvested lymph nodes could be explained by the age, lymph node metastasis, and pTNM stage (adjusted R2=11.2%). ConclusionsNumber of harvested lymph nodes in laparoscopic radical gastrectomy for advanced gastric cancer is greatly affected by the age of patients, lymph node metastasis, and pTNM stage. So patients should be evaluated objectively and individually according to their age so as to harvest sufficient number of lymph nodes, which is conducive to accurately judge pTNM stage, formulate accurate adjuvant treatment scheme, and improve prognosis of patients.
In 2014, the new concept of embolic stroke of undetermined source (ESUS) was first proposed by cryptogenic stroke/ESUS International Working Group. In the past 5 years, related clinical researches of ESUS have been deepened, and the results of many large clinical studies have been published. However, the guiding significance of this new concept to clinical practice is still controversial. By reviewing the background, diagnostic criteria, assessment, common emboli sources, anticoagulant therapy research advances and related limitations of ESUS, and analyzing the possible causes of negative anticoagulant therapy results, we explored the clinical value of this new classification.
