OBJECTIVETo evaluate the role of undermining orbicularis oculi muscle from Orbital rim for the correction of tear trough deformity and palabromalar groove in lower blepharoplasty.

METHODS56 cases of lower eye baggy deformity with tear trough deformity and palabromalar groove were treated with the procedure of stripping eye orbicularis oculi muscle from orbital rim by a transcutaneous approach in lower blepharoplasty. The orbital septum was opened along the arcus marginalis for releasing the orbital fat. Some orbital fat was removed if necessary. Then the inferior edge of the orbital septum fat was reset over the orbital rim so as to smooth the infraorbital groove.

RESULTS56 patients were available for 6 to 18 month's follow-up. 54 patients were quite satisfied with the cosmetic result. One developed lower eyelid retraction and another one showed asymmetrical subcutaneous local uneven after 1 month's. They were all corrected by the second operation after 3 months.

CONCLUSIONSStripping orbicularis oculi muscle from orbital rim plays an important role for the correction of tear trough deformity and palabromalar groove in lower blepharoplasty.

Background Age-related cataract is one of the common causes of blindness.Although the pathophysiology of age-related cataract is far from clearly understood,it is well accepted that DNA damage plays an important role in the disease pathogenesis.Objective The purpose of this study was to quantitatively evaluate the DNA damage in peripheral lymphocytes of age-related cataract.Methods A cross-sectional study was carried out.This study complied Declaration of Helsinki and approved by Ethic Committee of Affiliated Hospital of Nantong University.Written informed consent was obtained from each subject.Two hundred and eleven patients with agerelated cataract and 147 normal subjects were enrolled from a “ Jiangsu Eye Study:Funing 2011 Eye Disease Epidemic Survey”.All the subjects aged from 50 through 80 years with matched age and gender between the two groups.The percentage of tail DNA and Olive tail moment (OTM) were detected by comet assay to assess the extent of DNA damage in peripheral lymphocytes.Statistical analyses were performed with SPSS 17.0 software,and the differences of the percentage of tail DNA and OTM were compared between the age-related cataract group and normal control group by independent sample t test as well as among the 50-59 years group,60-69 years group and ≥70 years group by one-way analysis of variance.Results Comet assay showed a round lymph cell with the clear border in the normal group;while in the age-related cataract group,the cell was bigger with a comet-like tail.The percentage of tail DNA and OTM in peripheral lymphocytes were (21.75 ± 3.51) ％ and 6.54 ± 1.65 in the age-related cataract group,and those in the normal control group were (9.31 ±3.60)％ and 2.18 ± 1.10,respectively,with significant differences between them (t =32.67,P =0.00 ; t =28.02,P =O.00).In the 50-59 years subgroup of the age-related cataract group,the percentage of tail DNA and OTM in peripheral lymphocytes were (20.04±2.86) ％ and 5.92± 1.14,and in the 60-69 years subgroup of the age-related cataract group,the percentage of tail DNA and OTM in peripheral lymphocytes were (20.77 ±2.93) ％ and 6.13 ± 1.14,which were significantly reduced in comparison with (22.79 ± 3.67)％ and 6.95±1.91 of the ≥70years subgroup(TailDNA％:q=2.75,P=0.00; q=2.02,P=0.00;OTM:q=1.03,P =0.02 ; q =0.82,P =0.00).Conclusions The pathogenesis and development of age-related cataract probably is associated with DNA damage.

Objective: This study aimed to compare the short- and long-term outcomes of laparoscopy-assisted radical gastrectomy between elderly and non-elderly patients with gastric cancer. Methods: A total of 219 patients who underwent laparoscopy-assisted radical gastrectomy in the Department of Gastrointestinal Surgery IV, Peking University Cancer Hospital & Institute from April 2009 to October 2013 were included in this retrospective study. All patients were divided into elderly (≥65 years) and non- elderly (<65 years)groups. We compared these groups based on clinicopathological characteristics, postoperative morbidities, and survival. Results:Theelderly group showed higher ASA scores and higher number of preoperative comorbidities (P<0.05). The operative time, blood loss,and conversion rate did not differ significantly between the groups (all P>0.05). The mean time to first ambulation in elderly group was 2.2±2.3d while first ambulation time in the non-elderly group was 1.4±1.3d,which showed significant difference between the two groups (P<0.05). No significant differences were observed between groups in terms of postoperativemorbidities (34.8％ vs. 28.5％, P> 0.05) as well as 3-year disease-free survival and overall survival (P>0.05). However, the elderly patients withpostoperative morbidities experienced significantly poorer overall survival rate than non-elderly patients (44.5％ vs. 70.5％, P<0.05). Conclusion: Laparoscopy-assisted gastrectomy can be safely and successfully performed in an elderly population with acceptable short- and long-term outcomes.Enhanced perioperative treatment is necessary to improve postoperative outcomes.

OBJECTIVETo investigate the clinical manifestations, pathological characteristics, and treatments of urothelial-type mucinous adenocarcinoma of the prostate (UMAP).

METHODSWe reported a case of UMAP, reviewed relevant literature, and analyzed the clinicopaothological features, diagnosis, treatment, and prognosis of the disease.

RESULTSThe patient was a 60-year-old male and underwent transurethral resection of the prostate for dysuria. Postoperative pathology indicated mucinous adenocarcinoma and sigmoidoscopy revealed no primary colon cancer. Immunohistochemical staining showed the negative expressions of PSA and P504s and positive expressions of CK7, CK34 β E12, CK20, and CDX2. Thus UMAP was confirmed and treated by intensity-modulated radiotherapy. Then the patient was followed up for 30 months, which showed desirable therapeutic result, with neither local progression nor distant metastasis.

CONCLUSIONUMAP has a bad prognosis and its diagnosis depends on pathological and immunohistocchemical examinations. It responds well to radical prostatectomy but is not sensitive to endocrine therapy. Radiotherapy can be considered for those who are not fit to receive radical prostatectomy.

Objective To evaluate the prevalence of depressive symptoms and influencing factors among adolescents. Methods A total of 635 students aged 13 to 18 years were selected in March 2017 and were investigated with general information questionnaire, CES-D and CTQ-SF. Results 630 questionnaires are effective and the positive rate of depression was 29.84％(188/630) . The average score of CTQ was 32.15±2.98; 38.73％ of the students were disregarded and only 2.22％ of that were abused during their childhood. 40.00％ of the students had no CTQ, 1 kinds of CTQ accounted for 31.43％ , 2 kinds of CTQ accounted for 18.25％, and more than 3 CTQ accounted for 10.32％. Multivariate logistic regression analysis show that gender (OR=1.034, 95％ CI: 1.012-1.056) , parents' marital status (OR=1.124, 95％ CI: 1.087-1.162) , family atmosphere (OR=1.025, 95％ CI: 1.024-1.158) , CTQ cumulative number (ORCTQ=1=1.528, 95％ CI: 1.214-1.923; ORCTQ=2=3.067, 95％ CI: 1.325-7.102; ORCTQ≥3=10.361, 95％ CI: 3.059-35.093) were the risk factors for depression. Conclusion Gender, parents' marital status, family atmosphere and CTQ cumulative number were risk factors for depression in adolescents.

Purpose:To study the diagnostic value of using ultrasonography(US)、plain film of the abdomen(KUB)、 intravenous urography (IVU) in acute ureteral calculous obstruction. Methods: The routine B-US、diuretic US、 KUB、 IVU were retrospectively analyzed in 352 cases of acute ureteral calculous obstruction.Results: Of all the patients, 83.2 % (293/352) 、 96.6 % (340/352)were diagnosed as hydronephrosis by routine B-US、 routine B-US plus diuretic US, respectively. The hydronephrotic diagnosis of 59 suspected patients were79.7% (47/59)using diuretic US. The ureteral calculous dignosis of US、KUB、US plus KUB were 76. 1 % (268/352 )、81.6(284/348)and 91.8(323/352),respectively. Conclusion:The routine B-US is an effective method todiagnose acute upper urinary tract obstruction,and routine B-US plus diuretic US is more valuable. B-US plusKUB is the first approach to diagnose ureteral calculi.

AIM:To investigate the role of SDF-1α/CXCR4 axis in pancreatic cancer cell migration and invasion.METHODS:The mRNA expression of CXCR4 in 4 pancreatic cancer cell lines was detected by RT-qPCR.The migration and invasion abilities of PANC-1 cells with the axis activated by exogenous SDF-1αor inhibited by CXCR4 inhibitor AMD3100 were detected by Transwell assays.The cell viability was measured by MTS assay.The protein expression of the epithelial-mesenchymal transition (EMT) -related molecules in the cells treated with exogenous SDF-1αor AMD3100 was determined by Western blot.RESULTS:All of the 4 pancreatic cancer cell lines expressed CXCR4 mRNA, while the PANC-1 cell line expressed the most.Exogenous SDF-1αpromoted the migration and invasion abilities of PANC-1 cells, which was inhibited by AMD3100.The PANC-1 cells treated with exogenous SDF-1αfor 72 h grew faster, while SDF-1αcombined with AMD3100 made little significance to the viability of PANC-1 cells.Exogenous SDF-1αinduced EMT of PANC-1 cells by up-regulating the expression of SNAIL and TWIST, and AMD3100 reversed this effect.CONCLUSION:SDF-1α/CXCR4 axis enhances the migration and invasion abilities of pancreatic cancer cells through inducing EMT.

OBJECTIVETo investigate the role of real time quantitative polymerase chain reaction (RQ-PCR) in the diagnosis and treatment of recipients cytomegalovirus (CMV) infection after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODS318 patients received allo-HSCT were studied. 160 patients received transplants from HLA matched sibling donors; 127 from HLA mismatched related donors; 31 from unrelated donors. Before transplant recipients and donors received CMV serological test by ELISA. After transplant RQ-PCR was used to test and monitor CMV-DNA in plasma of patients. A positive CMV-PCR was defined as > 6 x 10(2) copies/ml. Ganciclovir was used for CMV prophylaxis in all patients at -9 d to -2 d of conditioning regimen period. Ganciclovir, foscarnet, or combination of the two drugs were used as the preemptive therapy.

RESULTSThe total 100-day cumulative incidence of CMV infection was 40.6%. The incidence was 17.5%, 66.1% and 45.2% for the HLA matched sibling, HLA mismatched related (MMR) and unrelated donor (MUR) HSCT respectively. Multivariate analysis showed MMR HSCT, MUR HSCT, ATG containing preparative regimen and moderate to severe aGVHD were the risk factors for CMV infection after HSCT. The 100 day cumulative incidence of CMV disease was 8.8% and 5.6%, 9.4%, 22.6% respectively for total and three kinds of HSCT after early preemptive therapy. Two-year survival of CMV infection was similar in the three kinds of SCT.

CONCLUSIONDetection of CMV DNA in plasma by real time PCR appears to be effective for the diagnosis and surveillance of CMV infection after HSCT. It may help to initiate antiviral therapy and reduce the incidence of CMV disease in the patients with high risk of CMV infection.
