Objectives：This study was designed to investigate the regulation effect of 8-Br-cAMP （ 8-Bromo 3′ ：5′ -cyclic adenosine monophosphate） on the expression of connexin gene (Cx43) in human tongue carcinoma cell line (Tca8113) . Methods：The inhibitory effect of 8-Br-cAMP on growth of Tca8113 cell line was examined by methyl thiazolyl tetrazolium (MTT) assay. Cx43 gene expression in Tca8113 cells after treated with 8-Br-cAMP was analyzed by immunocytochemistry and flow cytometry . Results：After treated with 8-Br-cAMP(10-5 mol/L, 10-4 mol/L, 10-3 mol/L), Tca8113 cells was inhibited and the inhibition rate was increased with the concentration of 8-Br-cAMP; Immunocytochemistry showed Cx43 protein detectability and up-regulation in 8-Br-cAMP treated cells; The positive rate of Cx43 protein in Tca8113 ce1ls increased from 4.8％ to 26.5％ . There was significant difference between 8-Br-cAMP treated cells and untreated cells （ P<0.01） . Conclusion： The anti-tumor effect of 8-Br-cAMP on Tca8113 cells might be due to up-regu1ation on Cx43 gene.

OBJECTIVETo evaluate the clinical effect of arthroscopic excision of the os subfibulare in anterior-lateral ankle pain.

METHODSFrom December 2005 to Augest 2014, 16 patients suffering from pain associated with an os subfibulare in the anterior-lateral side of their ankles were reviewed. Among the patients,11 patients were male and 5 were female, with a mean age of (33.5 ± 15.6) years old. The mean maximum diameter of os subfibulare was (0.70 ± 0.26) cm. All the patients underwent excision of the osseous fragments, and had anatomic reconstruction of the anterior talofibular ligament if the anterior-lateral ankle was instable. The average follow-up period was (18.0 ± 4.5) months. To analyze the surgical outcome, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot pain and function scales,visual analogue scale (VAS) and Tegner activity scale were assessed preoperatively and postoperatively.

RESULTSAOFAS scales were preoperative 60.15 ± 14.52 and postoperative 92.35 ± 5.73. There was a significant difference between them (t = -8.251, P = 0.000). The mean VAS score were preoperative 7.35 ± 0.46 and postoperative 2.45 ± 0.98. Statistical significance was also notable (t = 18.105, P = 0.000). Tegner score was significantly increased from preoperative 2.87 ± 1.12 to postoperative 5.78 ± 1.06 (t= -7.548, P = 0.000).

CONCLUSIONIrrespective of the size of os subfibulare, in patients with pain or instability associated with the os subfibulare, arthroscopic excision combined with reconstruction of ther anterior talofibular ligament or not was effective in restoring ankle function and eliminating pain.

Objective To explore the most accurate T staging and optimal surgical method of lung adenocarcinoma of trans-lobe type, and to provide supportive diagnosis as well as therapeutic evidences for this disease. Methods A total of 192 postoperative patients, hospitalized in Tianjin Medical University General Hospital from January 2008 to June 2013, who were diagnosed with lung adenocarcinoma were recruited. Patients were divided into three groups according to the 7th edition of TNM staging criteria issued by the IASLC in 2009. A total of 163 patients with T2 stage were selected as Group T2, and 12 patients with T3 stage were selected as Group T3, both of which were considered as control groups. Other 17 pa?tients who were diagnosed as trans-lobe type of lung adenocarcinoma, were Group trans-lobe. The clinical data and progno?sis were compared between three groups. The trans-lobe type of lung adenocarcinoma was diagnosed based on imaging and pathological examination. Subtypes of trans-lobe lung adenocarcinoma were identified by referring to 2011 international mul?tidisciplinary classification standard of lung adenocarcinoma. Kaplan-Meier method was used to analyze the prognosis of dif?ferent subtypes and surgical modus in patients with lung adenocarcinoma of trans-lobe type. Results By comparison, the postoperative survival rate was significantly lower in patients diagnosed with trans-lobe type of lung adenocarcinoma than that of Group T2 (P<0.05), and no significant difference in survival rate compared with Group T3 (P>0.05). There were no significant differences in survival rates between different surgical modus (P<0.05). Seventeen patients with trans-lobe type of lung adenocarcinoma consisted of four subtypes, including 8 solid predominant, 5 acinar predominant, 3 papillary predomi?nant and 1 invasive mucinous adenocarcinoma. There were no statistical significances in postoperative survival time and sur?vival rates between four subtypes. Conclusion The clinical stage of trans-lobe type of lung adenocarcinoma should be clas?sified as stage T3. Both pulmonary bilobectomy and lobectomy combined with resection of proximal invaded lobe can be used as effective surgical therapies for trans-lobe type of lung adenocarcinoma.

Objective To find out the iodine nutritional status of Longyan downtown residents,evaluate the effectiveness of control measures and provide a scientific basis for developing control strategies.Methods Infants aged 0 to 2 year-old,children aged 8 to 10,adults aged 18 to 45 and pregnant and lactating women were selected as survey subjects.Children goiter was detected with B ultrasound.Residents per capita daily salt intake was investigated by weighing method.Three urinary samples and a milk sample of lactating women were randomly collected.Urinary iodine and milk iodine content were determined by arsenic cerium catalytic spectrophotometric assay.Blood samples were collected and thyroid function (including serum TT3,FT3,TT4 and FT4) and thyroid stimulating hormone(TSH) were measured with direct chemiluminescence immunoassay,and thyroglobulin antibody(TgAb),thyromicrosome antibody(TMAb),and thyroglobulin (Tg) were measured with radioimmunoassay (RIA) in serum.ResultsThe goiter rate of children aged 8 to 10 was 1.8％ (2/110),and median thyroid volume was 2.75 ml.Household iodized salt coverage rate was 100.00％(318/318),and qualified iodized salt was 94.03％ (299/318).The daily per capita salt intake was (6.13 ± 3.56)g.The average medians of urinary iodine of the infants,children,adults,pregnant and lactating women were 181.8,315.2,196.6,158.7,136.4 μg/L,respectively.The median of milk iodine of lactating women was 155.6 μg/L.The proportions of serum TT3,FT3,TT4,FT4 and TSH which higher than normal were 3.6％ (11/308),0.6％ (2/309),23％ (7/309),1.0％ (3/313) and 1.3％ (4/312),respectively.While the proportions of serum TT3,FT3,TT4,FT4 and TSH that lower than normal were 2.3％ (7/308),11.7％(36/309),2.3％(7/309),12.8％(40/313),and 1.6％(5/312),respectively,of which 16 cases of both TgAb and TMAb were higher than normal.ConclusionsExisting salt iodine level is appropriate for 0 to 2 year-old infants and young children,18 to 45 year-old adults,pregnant and lactating women in downtown Longyan city.The iodine intake of children aged 8 to 10 is excessive.Thyroid function monitoring is recommended to be included in the routine monitoring.

【Objective】To evaluate the role of serum antimullerian hormone （AMH） concentration in predicting clinical outcomes in controlled ovarian stimulation and intrauterine insemination （IUI）. 【Methods】 A retrospective analysis of IUI data from patients with polycystic ovary syndrome and infertility in our reproductive center from January 2014 to August 2017. According to the clinical outcomes，data was divided into three groups：clinical pregnancy group，non-pregnant group，and cancellation cycle group due to multiple follicular or no dominant follicular develop. The ovarian function evaluation indexes were compared such as serum AMH，basal FSH and basal sinus follicle（AFC）. The cutoff values of the AMH to predict multi- follicular development or no dominant follicular development which IUI cycles were cancelled，and to predict obtain cumulative clinical pregnancy outcomes were calculated according to the ROC curve to cancel the cycle. 【Results】 The clinical pregnancy rates of PCOS patients were from 15.9% to 17.1% ，while the cumulative clinical pregnancy rate increased in repeat cycles （≤3 cycles） was 21.6% ，significantly higher than the average clinical pregnancy rate（16.7%）during the first cycle. AMH levels in the cancelled cycle group were significantly higher than those in the non-cancelled cycle group［（14.1±6.5）vs（10.3±4.3）ng/mL，（14.1±6.5）vs（9.3±4.3）ng/mL， P<0.025］. Compared with the clinical pregnancy group，cancel cycle group and non- pregnant group，the mean AFC of the former two groups were significantly higher［（34.5±11.4）vs（30.7±11.3），（7.8±10.8）vs（30.7±11.3），P<0.025］. In addition，we found that women′ s age，baseline FSH were negatively correlated with the cumulative pregnancy rate of repeated IUI cycles，and women′s baseline BMI，baseline LH，AFC，and AMH were positively correlated with cumulative pregnancy rates. The number of mature follicles on the HCG triggering day，as well as the value of AMH，may be the influencing factor of IUI cumulative clinical pregnancy. By ROC curve analysis，we assume that AMH is more suitable than the AFC to predict IUI cycle cancellation rate and the cumulative pregnancy rate.【Conclusion】Repeated IUI cycles can be improved cumulative pregnancy rate of PCOS infertile couples. AMH，as an important index to measure ovarian reserve function，can be used to predict the the IUI cumulative clinical pregnancy outcomes and cancelled cycle rates：as AMH increased to more than 6.56 ng/mL，the pregnancy rate increased；but when AMH ≥14.72 ng/mL，the risk of cancelled IUI cycles was increased，becasues of multi-follicular developing and absence of dominant follicle development.

【Objective】The aim of this study was to investigate the proportion of dominant follicles（PDF）on HCG day in young and aged women.【Methods】In total，3 064 cycles of GnRH agonist long protocol and 918 cycles of GnRH antagonist protocol from 2014 to 2016 were retrospectively included. Patients were divided into 3 groups（low PDF，< 20%； medium PDF，≥20% and ≤40% ；high PDF，> 40%）. The measurements regarding the ovarian stimulation characteris? tics ，clinical pregnancy rate was compared between different PDF groups stratified by age and protocol. 【Results】 In patients aged ≤30 years who received the GnRH agonist long protocol，no significant difference was found in the clinical pregnancy rate between the different PDF groups（P > 0.05）. Regarding the GnRH antagonist protocol，no significant difference was found in the clinical pregnancy rate and moderate or severe OHSS rate（P > 0.05）. In patients aged ≥40 years， the clinical pregnancy rate in the low PDF group was higher than that in the high PDF groups（40% vs. 30.88%）in GnRH agonist long protocol. Concerning the GnRH antagonist protocol，patients in the low PDF group had a significantly higher clinical pregnancy rate than those in the other two groups（27.27% vs. 9.09% ，7.40% ；P = 0.002）.【Conclusions】PDF within 20% is recommended for older patients（≥40 years），especially in those receiving the GnRH antagonist protocol.

Current formulas tend to select intraocular lens with insufficient power for these patients, resulting in postoperative hyperopia. In addition to the traditional methods to address this problem such as reserving a myopic power in the power calculation, several more accurate and effective solutions have been suggested, including adjusting the axial lengths, using new formulas, and applying intraoperative refractive biometry. This paper will focus on the postoperative refractive error in highly myopic eyes after phacoemulsification and intraocular lens implantation and illustrate the progress of existing solutions.
