Objective To evaluate the effect of health education in controlling the iodine deficiency diserders(IDD) in order to provide reference data for the further prevention and control. Methods Each village of 3 towns in Congjiang County was selected in 2007, where the health education lasting for 10 months had been implemented in the school students of 3-6 grade and the villagers. The school students of 3-6 grade and 30 housewives in the villagers were investigated for their IDD control knowledge, the salt consuming conditions as well as the sales of both rough and fine salt at a salt retail site in each village before and after the health education was implemented. Results The awareness rate of the knowledge of IDD control in the students and housewives was 91.4% (581/636) and 78.3% (282/360), respectively after intervention, which significantly increased (χ2= 532.044, 326.117, both P < 0.01) compared with the rate of 28.2% (184/652) and 11.4% (41/360) before intervention. The proportion of consuming fine salt was 91.8%(146/159) and 95.6%(86/90), significantly inereased(χ2= 236.623, 135.350, both P < 0.01) compared with 6.1%(10/163) and 7.8% (7/90) found before intervention. The selling proportion of fine salt at the salt retail site in the village was 60.0%(900/1500), significantly increased(χ2= 824.176, P < 0.01) compared with 10.0%(150/1500) before intervention. Conclusions Health education and promotion is solid foundation for effectively controlling IDD, through which the students and villagers are actively and voluntarily involved in the program and hence have formed good living and hygiene habits, thus expected effect has been obtained.

BACKGROUNDOsteopontin (OPN) is one kind of cytokine which can play a number of roles in promoting activation of T lymphocyte, regulating balance between Th1 and Th2, participating in cell-induced immunologic response and stimulating B lymphocyte to express multi-clone antibodies. Some researches have showed that OPN may be involved in the pathogenesis of systemic lupus erythematosus (SLE). The aim of this study was to investigate possible association of a single nucleotide polymorphism (SNP) at position 9250 in exon 7 of the OPN gene (OPN gene 9250) with SLE in Chinese patients.

METHODSTotally 158 patients (18 males and 140 females) fulfilled the revised criteria for SLE by the American College of Rheumatology in 1982 and 180 healthy volunteer controls (34 males and 146 females), all from the south of China, consented to participate in the study. OPN gene 9250 polymorphism was detected by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP).

RESULTSThe frequency of TT genotype of the OPN gene 9250 was significantly lower (52.5% vs 70%, P < 0.05) and the frequency of TC genotype of the OPN gene 9250 was significantly higher (43.7% vs 29.4%, P < 0.05) in SLE patients than in controls. There were significant differences in OPN gene 9250 allele and phenotype frequencies between the SLE patients and controls (P < 0.05). When the SLE patients and controls were separated into men and women, significant differences of frequencies were noted in TT genotype, TC genotype and allele of the OPN gene 9250 in women (P < 0.05) but not in men (P > 0.05).

CONCLUSIONSOPN gene 9250 polymorphism appears to be associated with susceptibility to SLE in Chinese Han ethnic population.

OBJECTIVETo validate those obtained immunogenic membrane antigens candidate of human pancreatic cancer in the performed research.

METHODSIn the pre-studies, serum IgG purified from clinically collected sera of pancreatic cancer patients underwent immunoblot with human pancreatic cancer cell line SW1990 membrane protein, totally obtained 9 positive protein spots. Number 5 and 6 positive dots of immunoblot were identified by matrix-assisted laser desorption/ionization-time of flight mass spectrometry and peptide mass fingerprinting matching. The candidate membrane antigens were further validated in cell lines by RT-PCR and real-time PCR. RNA of human normal pancreatic tissue and pancreatic cancer tissue was extracted respectively, different gene expression level of prohibitin 2 was studied by real-time PCR.

RESULTSNumber 5 and 6 positive dots were identified as prohibitin 2 and prohibitin. RT-PCR and real-time PCR all showed that gene of prohibitin 2 and prohibitin were expressed in the human pancreatic cancer cell line SW1990, AsPc and P3 respectively, especially in P3 cell with highest expression (t = 7.442, P < 0.01). In addition, gene expression level of prohibitin 2 was significant higher in human pancreatic cancer than that of normal pancreatic tissue (t = 0.893, P < 0.01).

CONCLUSIONSProhibitin 2 and prohibitin are both differently expressed in the pancreatic cancer cell line SW1990, AsPc and P3. Prohibitin 2 is obvious highly expressed in human pancreatic cancer tissue. Prohibitin 2 and prohibitin might be the candidate immunogenic membrane antigens of human pancreatic cancer.

Objective The treatment methods for blood blister-like aneurysm remain controversial due to its special patholog-ical structure,the risk of post-operative rebleeding and the high rate of recurrence. The arm of this paper is to access the feasibility and effectiveness of overlapping stent-assisted coiling in the treatment of blood blister-like aneurysms of the internal carotid artery. Methods Form January 2014 to December 2016,we treated 15 patients with blood blister-like aneurysm of the internal carotid artery by stent-assisted coiling in the Department of Neurosurgery,5 with two Enterprise tents,3 with three Enterprise tents,4 with Enter-prise+LVIS tents,and 3 with two LVIS tents. We determined the rate of immediate embolization of aneurysms by Raymond-Roy Occlu-sion Classification(RROC)and analyzed the clinical characteristics,postoperative complications,and follow-up data. Results All the coils and stents were successfully implanted. RROC showed 9 cases of gradeⅠ(60%),4 cases of gradeⅡ(27%),and 2 cases of gradeⅢimmediate occlusion(13%),with the parent arteries unobstructed in all the cases. Thrombosis in the stent was found in 2 cases intraoperatively,slight stent migration in 1 case,and internal carotid artery dissection in the petrous segment in another,but no cer-ebral vasospasm or aneurysm rupture in any case.Delayed cerebral in-farct was observed in 2 cases postoperatively. The patients were fol-lowed up for 2 weeks to 28 months,which showed that 11 of them were cured,2 remained stable and 2 developed further thrombosis,with an MRS score of 0-2 in 12 cases,4 in 1 case,5 in 1 case, and 6 in 1case. Conclusion Overlapping stent-assisted coiling is effective for the treatment of blood blister-like aneurysm by reduc-ing the risks of rebleeding and recurrence.

OBJECTIVESTo analyze the survival outcomes of the surgery for colorectal cancer with liver metastases (CRCLM), and study the mode of multi-disciplinary team (MDT) for CRCLM.

METHODSThe retrospective analysis was conducted for 38 patients with CRCLM received MDT management and surgical treatment from January 2009 to August 2011. The peri-operative and survival outcomes of MDT and surgery were evaluated.

RESULTSAll the cases met the present criteria of resetability for CRCLM, but only 4 cases (10.5%) met the previous one. Coloproctectomy and hepatectomy were performed in all cases, with 39 colorectal neoplasms and 155 liver lesions removed. One case died of postoperative septic shock. Colorectal and hepatic specific complications were absent in the others patients except one case of biliary leak which was treated with conservative management. Neoadjuvant chemotherapy was arranged in 13 cases. Adjuvant chemotherapy was administered for every patient. After a mean follow-up of (22 ± 10) months according to the finding time of liver metastases, recurrence and metastases were observed in 16 cases and 6 cases died of late-stage cachexia. The 1-, 2- and 3-overall survival rate were 94.4%, 85.3% and 75.8% respectively, and the 1-, 2- and 3-disease-free survival rate were 70.1%, 54.2% and 54.2% respectively.

CONCLUSIONSMDT mode for resectable CRCLM is recommendable. Surgical resection of CRCLM is feasible and safe, which seems to achieve favourable short-middle oncologic outcomes. And long-term survival is expected.

【Objective】To study the expression of Tip60（KAT5）in Oral squamous cell carcinoma（OSCC），and to investigate the relationship of Tip60（KAT5）and OSCC.【Methods】Forty-nine samples of OSCC and 36 samples of nor⁃ mal tissue adjacent to OSCC were collected and analyzed retrospectively. The expression of Tip60（KAT5）was detected by immunehisto chemistry using Envision detection system. OSCC cell line Cal27 and UM1 cultured in vitro were treated with Nu9056，an inhibitor of Tip60（KAT5）for 24h，respectively. Then the effect of different concentrations and times on the growth of Cal27 and UM1 cells was evaluated with MTT assay.【Results】The expression of Tip60（KAT5）in OSCC was significantly higher than that in normal tissue adjacent to OSCC（P=0.000）. Its expression was significantly positively correlated with the degree of histological differentiation（r=0.461，P=0.001）. With the increase of concentration，the proliferation inhibition rate of Nu9056 on Cal27 and UM1 cells gradually increased，showing a concentration- dependent and time-dependent relationship（P<0.05）.【Conclusions】The expression of Tip60（KAT5）protein in oral squamous cell carcinoma tissues was related to the degree of histological differentiation ，Tip60（KAT5）can be used as oral squamous cell carcinoma progression and prognosis of biological indicators.
