ObjectiveTo investigate the expression of Ezrin and inducible nitric oxide synthase (iNOS) and their correlation to malignant proliferation of colonic adenoma. MethodExpressions of Ezrin,iNOS and nuclear Ki-67 antigen were detected by immunohistochemistry in tubular adenoma (60 cases),villous adenoma(40 cases) and malignant (30 cases ) pleomorphic adenoma. ResultsExpressions of Ezrin,iNOS in tubular adenoma [58.3％ (35/60), 50.0％ (30/60)], villous adenoma [72.5％ (29/40), 70.00(28/40)]and malignant pleomorphic adenoma [96.7％(29/30),93.3％(28/30)]were gradually increased ( X2 = 11.600,P = 0.005; X2 = 8.451, P = 0.015 ). There was a significant positive correlation between the expression of Ezrin and iNOS (r = 0.765, P ＜ 0.01 ). Nuclear Ki-67 antigen proliferation index was increased with the increasing of Ezrin and iNOS expressions. ConclusionOverexpression of Ezrin and iNOS may promote proliferation and malignant transformation of colonic adenoma.

OBJECTIVETo explore the effect of auricular point sticking before operation for postoperative complications of external excision and internal ligation on mixed hemorrhoid.

METHODSEighty patients with mixed hemorrhoid were randomly divided into an observation group and a control group, 40 cases in each group. In the control group, paracetamol and dihydrocodeine tartrate tablets were applied with oral administration 1 h after operation, 510 mg each time, twice a day; at the same time, diosmin tablets were treated with oral administration, 0.9 g each time, twice a day. Three days' treatments were required successively. In the observation group, auricular point sticking was used before operation based on the treatment in the control group. The auricular points of Shen (Co10), Pangguang (CO9), Shenmen (TF4), Pizhixia (AT4), Jiaogan (AH6a) and Gangmen (HX5) were selected. The patients were asked to press the points 3-6 times per day, 3-5 min each time, 3 days' treatment in total. The scores of the postoperative complications in the 1st and the 2nd days were compared between the two groups such as pain, edema, hematochezia, retention of urine, etc.

RESULTSAfter operation, the scores of pain, edema, hematochezia, retention of urine in the 2nd day were all decreased obviously than those in the 1st day in the two groups (all P<0.05); and the scores of pain, edema, hematochezia, retention of urine in the 1st and the 2nd days of the observation group were lower than those in the control group (all P<0.05).

CONCLUSIONAuricular point sticking before operation combined with conventional western medicine with oral administration for preventing and treating postoperative complications of external excision and internal ligation on mixed hemorrhoid achieves positive and reliable efficacy.

In the thyroid surgery,parathyroid and laryngeal recurrent nerve injury is the most common complications.With the deepening understanding of the laryngeal recurrent nerve anatomy and surgical skills,laryngeal recurrent nerve injury incidence decline,and the prevention of complications of thyroid operation has turned to protect the parathyroid gland from laryngeal recurrent nerve protection.The technique of carbon nanoparticles labeled lymph nodes can effectively protect the parathyroid gland in thyroid surgery.

Objective To analyze the clinical characteristics of spinal cord injury patients with postoperative adhesive intestinal obstruction, and summarize the clinical experience of diagnosis and treatment. Methods 35 spinal cord injury patients with postoperative adhesive intestinal obstruction in our department from August 2008 to August 2013 were reviewed. Results All of them had a history of abdominal surgery for various reasons, 22 cases received sigmoid colon pouch procedure and 13 cases received cholecystectomy. 25 cases suffered T10-L1 spinal cord injury, 10 cases suffered cervical spinal cord injury; 26 cases (74.3%) received non-operative treatment and recovered, 9 cases (25.7%) were transferred to surgery. Conclusion There is no typical clinical symptom and sign in spinal cord injury patients with adhesive intestinal obstruction after abdominal surgery, so early diagnosis is difficult, and the imaging examination is necessary. When non-operation treatment is not effective to these patients, surgical treatment should be timely carried out.

ObjectiveTo analyze the relative influential factors of hearing rehabilitation of the deafened children with multichannel cochlear implant. Methods42 prelingually deafened children who accepted multichannel cochlear implant were evaluated with their hearing ability, hearing thresholds and talent level, while their family and usage of the multichannel cochlear were investigated. Results and ConclusionThe result shows that the factors influencing the hearing rehabilitation are the occupations of the parents, income of the family, the time between diagnosing deaf and the operation, the time after the cochlear implant operation and the talent level. The results of the logistic regression show that the deafened children can gain their hearing developing rapidly if they living in a family with high income, their mothers have accepted more education, and they accepted longer time of continuing hearing-aid, etc.

Objective To study whether the mechanism of mifepristone in treating adenomyosis is suppressing matrix metalloproteinase-9 and tissue inhibitors of metalloproteinase-1(MMP-9/TIMP-1). Methods Thirty-five patients in the mifepristone treated group(19 cases of adenomyosis) and the control group(16 cases of adenomyosis,non-drug treated) underwent hysterectomy.Endometrium was looked as eutopic endometrium and adenomyosis as ectopic endometrium.Expression of MMP-9 and TIMP-1 in eutopic and ectopic endometrium were measured by immunohistochemical techniques. Results The ectopic endometrium of the mifepristone treated group expressed lower level of MMP-9,higher level of TIMP-1 and lower ratio of MMP-9/TIMP-1 than the ectopic endometrium of the control group(P

ObjectiveStromal cell-derived factor -1 (SDF-1 ) is closely related to the biological characteristics of breast cancer. We aimed to explore whether estrogen affected breast cancer by SDF-1. MethodsThe breast cancer cell line MCF-7 and MRC5 were chosen, and divided into three groups: the control group, the estrogen group and the estrogen + estrogen receptor blocker group. Each group was cultured with different physiological concentrations of 17-β estrogen at certain time, and the same alcohol concentration of 17-β estradiol at different time points, and then the enzyme-linked immunosorbent assay (ELISA) was used to measure the concentration of SDF-1 in culture medium, and the semi-quantitative reverse transcriptionpolymerase chain reaction (RT -PCR) was used to detect the expression of SDF-1 mRNA in each group.ResultsSDF-1 can be detected in the culture medium of both MCF-7 and MRC5 cell lines. All different concentrations of 17-β estradiol may increase the secretion of SDF-1 in MCF-7 cells. When adding 17-β estradiol to the concentration of 107mol/L, the secretion of SDF-1 reached the peak in 2 hours, which was 6 times and 2.7 times that of control group ( P ＜ 0.01 ). The effect could be ehminated by pure estrogen receptor ICI182,780. In addition, the mRNA expression of SDF-1 was consistent with the SDF-1 protein levels-l07 mol/L group. The expression of SDF-1 mRNA was higher than both that of the control group and the blocking group in 2 hours (P ＜ 0.05 ). ConclusionsIn some breast cancer cell lines, physiological concentrations of estrogen can increase the secretion of SDF- 1, and this effect is mainly achieved through the estrogen receptor. Estrogen can influence the biological characteristics of breast cancer by SDF-1.

Objective To study the relationship between nitric oxide within cervical microenvironment and different HPV types as well as the effect of sodium nitroprusside( SNP), a nitric oxide donor, on the proliferation and apoptosis of cervical cancer cell lines. Methods HPV typing test was assessed from 115 women by using high-risk HPV (HR-HPV) 21 typing test and the release of cervical nitric oxide(NO) was assessed as nitrate, nitrite in cervical fluid. Cervical NO was then compared between women showing different HPV types. Proliferation of Caski and HeLa cervical cells was determined by methyl thiazolyl tetrazolium (MTT) assay, cell apoptosis was detected by flow cytometry after 24 hours treated by different final concentration of SNP (0. 125,0. 25,0. 5,1.0 and 2. 0 mmol/L, respectively). The expressions of HPV E6,E7 gene mRNA and p53 protein were detected by SYBR Green Ⅰ quantitative real-time PCR and western blot. Results ( 1 ) The cervical NO release of women with HR-HPV was higher compared to that in HPV negative women [ (47. 6 ± 1.4) μmol/L vs ( 22. 8 ± 0. 3 ) μmol/L; P ＜ 0. 05 ]; but there was no statistical difference between low-risk HPV (LR-HPV) group [ (24. 1 ± 1.2 ) μmol/L] and control group (P ＞0. 05 ). (2)After 24 hours treated by different final concentration of SNP, the results shown that SNP could inhibited the proliferation and increased apoptosis rate in Caski and HeLa cells, in which the concentration of SNP ≥ 1.0 mmol/L , there were significantly different ( P ＜ 0. 05 ), while when SNP ≥2. 0mmol/L, the proliferation of cells inhibited seriously. Treated by SNP ( 1.0 mmol/L ) 24 hours, the expressions of HPV18 E6, E7 mRNA in HeLa cells were reduced from 27. 362 ±0. 191,22. 962 ±0. 053 to19. 181 ±0. 360, 17. 571 ±0. 010 and the protein expression of p53 increased from 1. 17 ±0. 03 to 0. 23 ±0. 05, there were statistically significant differences between adding SNP group and the control group ( P ＜0. 05); but there were no statistically significant differences in HPV16 E6, E7 mRNA and that of p53 in Caski cells( P ＞ 0. 05 ). Conclusions The presence of HR-HPV is associated with an increased release of NO in the human uterine cervix; NO could inhibit the growth and proliferation and enhance the apoptosis of cervical cancer cells, inhibit the expression of HPV18 E6, E7 mRNA in HeLa cells and activate the expression of p53 protein, the mechanism may be due to higher sensitivity of HeLa cells (cervical adenocarcinoma cell) to SNP. The increasing release of NO may play a role in regulating the elimination of HPV in cervical microenvironment, which is a part of mucous membrane immunity.
