Objective To analyze the clinical effects of procedure for prolapse and hemorrhoids combined with external hemorrhoidectomy in the treatment of mixed hemorrhoid. Methods Clinical data of 108 patients with mix hemorrhoid who were admitted to our hospital from January 2012 to January 2014 were retrospectively analyzed. The 108 patients were assigned to an observation group and a control group according to the surgical procedures. 54 patients in the ob-servation group received procedure for prolapse and hemorrhoids combined with external hemorrhoidectomy, and 54 pa-tients in the control group received the conventional Milligan-Morgan operation. Each clinical index, pain conditions within 3 days after surgery and complications within 6 months after the surgery in the two groups were compared. Re-sults Surgery time, amount of bleeding during surgery, hospitalization time, and hospitalization expenses in the observa-tion group were all significantly better than those in the control group, and the differences were statistically significant (P<0.05). Pain scores in 24 h, 48 h, and 72 h after the surgery in the observation group were significantly lower than those in the control group, and the differences were statistically significant (P<0.05). In 24 h, 48 h and 72 h after the surgery, patients in the observation group had suffered less pain than those in the control group. Except for one of the patients who had complications before the surgery, total incidence of complications within 6 months after the surgery in the observation group was 18.51%, significantly lower than that of 81.50% in the control group, and the difference was statistically significant(P<0.05). Conclusion The procedure for prolapse and hemorrhoids combined with external hemor-rhoidectomy in the treatment of mix hemorrhoid has favorable effects of lower pain degree and less incidence of com-plications, and the combined procedure is suitable to be further promoted and applied clinically.

Objective To evaluate the changing trend of serum thyrotropin (TSH) levels for hemithyroidectomy patients,and to discuss the necessity and strategy of TSH suppression for low-risk differentiated thyroid carcinoma(DTC). Methods One hundred and twenty-seven patients with benign thyroid nodules undergoing hemithyroidectomy between January 2013 and June 2014 were retrospectively studied. Serum thyroid hormones levels FT3,FT4,TSH,thyroid peroxidase antibody(TPOAb),and thyroglobulin antibody(TGAb)were detected at 1 month after surgery for all patients and at 3 month for 54 patients. Results (1)Mean TSH level at 1 month after surgery was significantly higher than preoperative TSH level(2.45 mIU/L vs 2.20 mIU/L,n=127,P<0.01). The mean TSH level at 3 month after operation was significantly higher than preoperative ones(2.46 mIU/L vs 2.35 mIU/L,n=54, P<0.05). (2)TSH<2. 0 mIU/L was found in 52 patients(40. 9%) and TSH>4. 94 mIU/L in 18 patients (14.17%) at 1 month after operation. TSH<2.0 mIU/L was found in 28 patients(51.85%)and TSH>4.94 mIU/L in 8 patients(14.81%) at 3 month after operation. (3)A preoperative TSH≥2.0 mIU/L and the coexistence of Hashimoto's thyroiditis were found to be independent risk factors for the TSH levels higher than 2.0 mIU/L. Among the patients with TSH≥2. 0 mIU/L at 1 month, 13 exhibited spontaneous recovery at 3 month, coexistence of Hashimoto's thyroiditis was related to this phenomenon. Among the patients with TSH<2.0 mIU/L at 1 month,TSH levels were elevated over 2. 0 mIU/L in 7 patients by 3 month comparing to that by 1 month. Coexistence of Hashimoto's thyroiditis was independent risk factor for the TSH elevation. Conclusion TSH suppression may still be performed to patients with low risk DTC after operation especially to whom the preoperative TSH≥2.0 mIU/L and the coexistence of Hashimoto's thyroiditis. Suppression therapy should be carefully considered with close follow-up.

Objective To study the influence of micro (miR)-325 in progression of glioma and its molecular mechanism by regulating transferrin receptor (TFRC) gene expression in glioma cells. Methods (1) Thirty-five glioma tissues and paired adjacent normal tissues were collected during surgical excision performed in our hospital from January 2015 to January 2018. The miR-325 and TFRC mRNA expression levels in the glioma tissues and paired adjacent normal tissues were detected by inverse transcription-quantitative PCR (RT-qPCR); the expression of miR-325 in glioma tissues of patients with different clinical characteristics and the survival curves of patients with low or high miR-325 expressions were compared. (2) RT-qPCR was used to examine the miR-325 expression in HA, U251, and U87 cell lines in vitro; the regulatory relations between miR-325 and its potential target gene TFRC in U251, and U87 cell lines were measured by luciferase report assay; miR-325 mimic and its negative control were transfected into U251 and U87 cell lines for 48 h, and then, the mRNA and protein expressions of TFRC were detected by RT-qPCR and Western blotting, respectively; control small interfering RNA (siRNA)+nonsense inhibitor, TFRC siRNA+nonsense inhibitor, and siTFRC+miR-325 inhibitor were transfected into U251 and U87 cell lines for 48 h, respectively, Western blotting was employed to detect the TFRC protein expression, cell proliferation was detected by CCK-8 assay, and cell invasion was detected by Transwell assay; pcDNA3.1 empty vector+nonsense sequence, TFRC pcDNA3. 1+nonsense sequence, TFRC pcDNA3.1+miR-325 mimic were transfected into U251 and U87 cell lines for 48 h, respectively, TFRC protein expression was detected by Western blotting, cell proliferation was detected by CCK-8 assay, and cell invasion was detected by Transwell assay. Results (1) As compared with those in the adjacent tissues, the miR-325 expression was significantly decreased and the TFRC mRNA expression was statistically increased in glioma tissues (P<0.05); the TFRC mRNA expression and miR-325 expression were negatively correlated in glioma tissues (P<0.05); as compared with patients with Karnofsky functional status scores≥80, patients with scores<80 had significantly decreased miR-325 expression; as compared with glioma tissues of WHO grading I-II, glioma tissues of grading III-IV had significantly decreased miR-325 expression (P<0.05); the survival rate of patients with low miR-325 expression was statistically lower than that of patients with high miR-325 expression (P< 0.05). (2) As compared with that in HA cells, the miR-325 expression was statistically down-regulated in U87 and U251 cells (P<0.05); in TFRC wild-type (TFRC WT) transfected cells, the miR-325 mimic group had significantly lower luciferase activity than the nonsense sequence group, while the miR-325 inhibitor group had significantly higher luciferase activity than the nonsense inhibitor group (P<0.05); as compared with those in the nonsense sequence group, the TFRC mRNA and protein expressions were statistically decreased in U87 and U251 cells of miR-325 mimic group; as compared with those in the control siRNA+nonsense inhibitor group, the TFRC protein expression and absorbance value were significantly decreased, and number of invasive cells was significantly smaller in the siTFRC+nonsense inhibitor group; and as compared with those in the siTFRC+nonsense inhibitor group, the TFRC protein expression and absorbance value were significantly increased, and number of invasive cells was significantly larger in the siTFRC+miR-325 inhibitor group (P<0.05); as compared with the pcDNA3.1 empty vector+nonsense sequence group, the TFRC protein expression and absorbance value were significantly increased, and number of invasive cells was significantly larger in the TFRC pcDNA3.1 +nonsense sequence group, and as compared with the TFRC pcDNA3.1+nonsense sequence group, the TFRC protein expression and absorbance value were significantly decreased, and number of invasive cells was significantly smaller in the TFRC pcDNA3.1+miR-325 mimic group (P<0.05). Conclusion The miR-325 expression is decreased in glioma cells and has a tumor suppressor effect; patients with low miR-325 expression have poor prognosis; miR-325 inhibits cancer cell progression by inhibiting the expression of the target gene TFRC.
