Purpose To investigate the association between the macular volume and thickness,as assessed by optical coherence tomography(OCT),with refraction state and axial length(AL)in children.Methods A total of 100 normal children whose right eyes were randomly selected were divided into five groups due to their refraction,comprising hyperopia,emmetropia,low myopia,moderate myopia,high myopia.The AL of the eyes was measured by IOL master measuring machine.Then the macular volume and thickness were measured bv OCT.Results Children with high myopia have smaller macular volume and thinner parafoveal retinal thickness(especially out-ring macular).The minimum thickness and average thickness of the fovea were not significantly different among the five groups.The macular volume ,total average macular thickness and quadrant-specific macular thickness(except the nasal inner quadrants)were positively associated with refraction and negatively associated with AL,while there were no correlation between minimum foveal thickness,the average foveal thickness and refraction or AL.Conclusions In Chinese children,increasing axial length was associated with reduced maeular volume and thickness(except the foveal region and the nasal inner quadrant).

Objective To investigate retrospectively the therapeutic effect and safety of minimally invasive transthoracic device closure of isolated perimembranous ventricular septal defect (PVSD).Methods Eight hundred and ninety-one consecutive patients with PVSD from December 2008 to October 2014 in our hospital were enrolled,which performed minimally invasive transthoracic device closure of ventricular septal defect (VSD),with a 4 ～ 5 cm incision made on the inferior sternum.Under the guide of transthoracic echocardiography (TEE),right ventricular free wall was punctured followed by a delivery sheath threaded into the VSD and the occluder was released thereafter.Whether were there residual shunt and the occluder anchored firmly or not,the position of occluder and the influence on heart valve were re-evaluated intraoperatively by TEE.All patients were followed up prudently post-operation.Echocardiography and electrocardiogram were scheduled according to the protocol.Results Eight hundred and thirty-four cases were successfully occluded.Fifty-seven cases were performed VSD repair operation with cardiopulmonary bypass.The amounts of concentric occluder and eccentric occluder were 703 and 133,respectively.The patients performed minimally invasive transthoracic device closure of VSD had no severe complications after operation.Conclusions Although the short-term and mid-term therapeutic effect of minimally invasive transthoracic device closure of PVSD seem plausible to be definitive,with a favorable prospective application,the long-term follow-up remains to be studied.

Objective To investigate the feasibility,safety and clinical efficacy of three-port laparoscopic sleeve gastrectomy (TLSG).Methods The retrospective cross-sectional study was conducted.The clinical data of 104 obese patients who were admitted to the Beijing Friendship Hospital of Capital Medical University between September 2016 and March 2017 were collected.TLSG was performed to all the 104 patients by the same surgical team.The surgical situations,conversion situations (port-site increased or conversion to open surgery),operation time,volume of intraoperative blood loss,surgery-related complications,duration of postoperative hospital stay and follow-up situations were observed.Patients were followed up by Wechat,telephone interview and inpatient examination once at month 3,6,9 and 12 postoperatively and once every year after 1 year postoperatively up to April 2017.Follow-up included weight-loss efficacy and postoperative long-term complications.Measurement data with normal distribution were represented as x±s or average (range).Results All the 104 patients underwent successful TLSG,without port-site increased or conversion to open surgery.Operation time and volume of intraoperative blood loss were (121±25)minutes and (9±6)mL,respectively.There was no severe intraoperative collateral damage.All the 104 patients with complications were cured by symptomatic treatment,including 1 with port-site infection,1 with peritoneal effusions causing secondary infection,3 with improper eating-induced acute delayed gastric emptying,6 with fat liquefaction around port-site and 9 with delay healing of port-site.There was no occurrence of severe complications,such as gastrointestinal bleeding,intra-abdominal bleeding and gastrostoma.Duration of postoperative hospital stay was (2.4±0.8)days.Eighty-two patients were followed up for 3 months (range,3-6 months),including 59 with 3-month follow-up,23 with 6-month follow-up and 22 with under 3-month follow-up.During the follow-up,there was no port-site hernia.Excess weight loss (EWL) was 37％± 11％ in 59 patients with 3-month follow-up and 45％± 13％ in 23 patients with 6-month follow-up.Of 59 patients with 3-month follow-up,14 patients with diabetes mellitus stopped taking antidiabetic drugs,10 of 14 patients had complete remission (CR) of hemoglobin Alc (HbAlc) and 4 of 14 patients had partial remission (PR) of HbAlc.Of 23 patients with 6-month follow-up,6 patients with diabetes mellitus had CR of HbAlc.Of 18 patients with obstructive sleep apnea hypopnea syndrome (OSAHS),4 had 3-month follow-up,including 3 with CR and 1 was improved to mild OSAHS.Other 14 patients were not evaluated due to inadequate follow-up time.Conclusion TLSG for obese patients with specific indications cannot increase operation time and risk,meanwhile,it can reduce port-site,with a good cosmetic effect.

Structure of natural product-ursolic acid was modified for increasing its antitumor activity. Ursolic acid was acylated, esterified, hydrolized or oxidized to obtain target pentacyclic triterpenoid compounds with different substitutes. Sixteen derivatives of ursolic acid were designed and synthesized including eleven new compounds. Anti-tumor activities of ursolic acid and these derivatives against HeLa, SKOV3 and BGC-823 cells in vitro were investigated by MTT assay. The results indicated that compounds 7a and 8a were found to have stronger cell growth inhibitory than ursolic acid on HeLa cells and SKOV3 cells separately, and are worth to be intensively studied further.

OBJECTIVESTo investigate whether antisense Bmi-1 plasmid could inhibit the proliferation of Jurkat cells.

METHODSThe antisense plasmid was constructed by PCR amplification of a 171 bp segment spanning Bmi-1 start codon and zinc finger structure and the PCR product was subsequently inserted reversely to plasmid pLNCX2. The final construct was confirmed through restriction enzyme digestion. G418 was added into the medium after the plasmid was successfully introduced into Jurkat cells by using lipofectin-mediated DNA transfection. The proliferation of Jurkat cells were determined by MTT and colony formation assays. Cell cycle was determined by flow cytometry. The p16 expression of Jurkat cells was studied by immunofluorescent histochemistry.

RESULTSThe growth rate of antisense Bmi-1 transfected Jurkat cells was significantly lower than that of the controls, and the colony forming capacity of the transfected cells decreased significantly (P < 0.01), the colony numbers being (90.7 +/- 9.07)/10(3) cells, (83.3 +/- 6.11)/10(3) cells and (56.0 +/- 5.56)/10(3) cells for control cells, empty plasmid transfected Jurkat cells and antisense Bmi-1 transfected Jurkat cells, respectively. The percentage of G, phase cells was increased and the p16 expression of antisense Bmi-1 transfected cells was significantly upregulated than that of control cells.

CONCLUSIONAntisense Bmi-1 can inhibit the growth and upregulate the expression of p16 of Jurkat cells in vitro.

Objective To analyze retrospectively the therapeutic effect and safety of minimally invasive transthoracic device closure of perimembranous ventricular septal defect (PVSD).Methods One hundred and twenty-nine patients with PVSD from January 2011 to December 2011 in our hospital were selected and a 3 to 5 cm incision was made in the inferior sternum,which performed minimally invasive transthoracic device closure of ventricular septal defect (VSD).Right ventricular free wall was punctured and guided by transthoracic echocardiography (TEE),and then the occluder was released after a delivery sheath passed through the VSD.Location of occluder,effect on heart valve,fastness and residual shunt were evaluated by TEE instantly during operation.All patients were followed up intimately after operation,echocardiogram and electrocardiogram were rechecked regularly.Results One hundred and fourteen cases were successfully occluded.Fifteen cases were performed VSD repair operation with cardiopulmonary bypass.The amounts of concentric occluder and eccentric occluder were 96 and 20,respectively.The patients performed minimally invasive transthoracic device closure of VSD had no severe complications after operation.Conclusion Although the short-term therapeutic effect of minimally invasive transthoracic device closure of PVSD is definitely and has favourable prospect of application,the long-term follow-up remains to be studied.

OBJECTIVETo test the different contrctile responses of extracellular nucleotides, such as ATP, UTP and nucleotide uridine adenosine tetraphosphate (Up4A) in gastric longitudinal muscle (LM) and circular muscle (CM). Examined the effect of P2X and P2Y receptor antagonists (in this study, we used IP5I and suramin) and cyclooxygenase inhibitor (indomethacin) on Up4A induced contractile responses in LM and CM.

METHODSThe rats were sacrificed and the stomachs were opened to gain LM and CM. Using organ bath system to assess contrctile responses of smooth muscle.

RESULTSUp4A could induce contractile responses in both CM and LM, which were similar with ATP and UTP. IP5 did not attenuate Up4A could induce contractions in both LM and CM, but suramin and indomethacin significantly inhibited Up4A contraction in CM, but not in LM.

CONCLUSIONOur results suggest that extracellular nucleosides and their inhibitors induce different responses between LM and CM.
