OBJECTIVE: To evaluate the clinical outcome of Ruanjian Xiaoying Decoction (RJXYD) on chronic lymphocytic thyroiditis. METHODS: Eighty patients with chronic lymphocytic thyroiditis were randomly divided into RJXYD-treated group (n=40) and control group (n=40). The patients in the RJXYD-treated group received treatment of RJXYD combined with levothyroxine while the others in the control group received treatment of levothyroxine and prednisone both for 16 weeks. The serum levels of thyroid hormones and the titres of serum antithyroglobulin antibody (anti-TG Ab) and antithyroid microsomal antibody (anti-TM Ab) were all examined before and after treatment. The total response rates of the two groups were evaluated after treatment of 16 weeks. RESULTS: The total response rate of the RJXYD-treated group was 92.5%, while that of the control group was 60.0% (P<0.01). The serum levels of free triiodothyronine (FT(3)) and free thyroxine (FT(4)) were obviously increased after treatment as compared with those before treatment in the two groups. The titres of serum anti-TG Ab and anti-TM Ab and the serum level of thyroid-stimulating hormone (TSH) were all obviously decreased after treatment as compared with those before treatment in the two groups. CONCLUSION: The RJXYD can shrink and soften the enlarged thyroid gland and thyroid nodules, improve the immune function of human body, alleviate the response to thyroid self-antigens and promote the recovery of thyroid function.

AIM: To study the effects of norepinephrine preconditioning(NE-P) and ischemic preconditioning (IP)on apoptosis and Bcl-2, Bax expression in rat myocardial cells in myocardial ischemic reperfusion (I/R). METHODS: The model of rat ischemic-reperfusion was used to conduct NE-preconditioning. Apoptotic myocytes were detected with TUNEL. Bcl-2, Bax expression were detected with immunohistochemistry. RESULTS: The rate of apoptosis cells in I/R group was higher, the rate of apoptosis cells in NE-P group and IP was lower significantly than that in I/R group( P0.05). CONCLUSION: NE-P reduced myocyte apoptosis by I/R in rats; The expression of Bcl-2 ,Bax genes played an important role in myocardial apoptosis.

Colorectal cancer (CRC), as one of the most common gastrointestinal malignancy, is original from the epithelial/endothelial cells of colorectal tissues. CRC is one of the highest incidence and mortality rates of any malignancy in humans today. Moving forward the early diagnosis window of colorectal cancer, dynamic monitoring of the risk of postoperative recurrence and metastasis, early intervention is of great value in improving the diagnosis and treatment outcome of colorectal cancer. The clinical diagnosis of CRC via circulating tumor cells (CTC) has been considered as one of the fast, noninvasive, reproducible liquid biopsy methods, and it has been widely used in the early diagnosis, treatment monitoring and prognosis evaluation of colorectal cancer. This review systematically expounded the applied research values of CTC counting, protein expression (phosphatase of regenerating liver-3, matrix metalloproteinase, etc), molecular characterization (adenomatous polyp of colon, erb-b2 receptor tyrosine kinase, etc), mRNA expression profile and single cell sequencing in the diagnosis and treatment of colorectal cancer, in order to assist clinical in rational use of CTC monitoring indicators and provide support for improving the prognosis of colorectal cancer.

Objective:To explore the effect of cold-strap endoscopic mucosal resection (CS-EMR) in patients with colorectal polyps.Methods:A prospective randomized clinical trial was conducted to 320 selected patients with colorectal polyps diagnosed by Shenzhen Luohu District People′s Hospital from May 2019 to June 2021. The patients were randomly divided into CS-EMR group and HS-EMR group with 160 cases each, using a random number table generated by Excel 2007. The main parameters for statistical analysis contain the process indicators of the two groups of surgical methods, the complete polypectomy rate of patients after surgery, the degree of postoperative pain and the recovery of gastrointestinal function, and the differences in surgical complications.Results:The polypectomy time of CS-EMR group was shorter than that of HS-EMR group: (4.11 ± 1.20) min vs. (4.42 ± 0.98) min, with a statistically significant difference ( P<0.05). The score of visual analogue pain scale (VAS) in CS-EMR group was lower than that in HS-EMR group at 4 and 12 hours after operation: (3.11 ± 0.78) scores vs. (3.48 ± 0.80) scores, (3.38 ± 0.80) scores vs. (3.61 ± 0.92) scores, with a statistically significant difference ( P<0.05). The first anal exhaust time and first defecation time in CS-EMR group were lower than those in HS-EMR group: (27.83 ± 5.01) h vs. (29.66 ± 4.84) h, (43.73 ± 7.80) h vs. (47.28 ± 8.14) h, with a statistically significant difference ( P<0.05). The complications in CS-EMR group were significantly lower than those in HS-EMR group: 5.63% (9/160) vs. 12.50% (20/160), with a statistically significant difference ( P<0.05). Conclusions:The effect of CS-EMR in the treatment of colorectal polyps is not different from that of HS-EMR, but the former has the advantages of short resection time, rapid recovery of gastrointestinal function after operation, light pain and less complications.

Colorectal cancer is one of the most common gastrointestinal malignancies with high incidence rate and mortality rate. Human intestinal microbiota play crucial roles in multiple aspects including immune function, digestion and metabolism.Current research literature suggests that there is a significant connection between intestinal dysbacteriosis and colorectal cancer.However,it is not clear how intestinal dysbacteriosis is involved in the initiation, progress and metastasis of colorectal cancer.In this paper,the influence discussed from three aspects.
