Objective To evaluate long-term follow-up for laparoscopic anterior 180° partial fundoplication for gastroesophageal refulx disease (GERD).Methods A total of 48 patients had undergone a laparoscopic anterior 180° partial fundoplication from July 2004 to October 2007.Patients were followed up at 3 months,12 months,3 years,5 years by using a structured questionnaire via phone or e-mail which evaluated symptoms of reflux,dysphagia,side-effects,and overall satisfaction with the clinical outcome.Results Follow-up data were collected from 43 patients,ranging from 60 to 98 months.Postoperative heartburn significantly improved in 37 patients.Normal belching was preserved in 40 patients,and 38 patients were able to eat normally.Thirty nine (90.7%) patients reported a good or excellent result (minimal or no symptoms) at the late follow-up.Two patients underwent laparoscopic anterior 180° partial fundoplication again due to acid reflux at the 12th and 38th month respectively.Conclusion At minimum 5 years followup,laparoscopic anterior 180° partial fundoplication for GERD is effective and lasting,and most patients are satisfied with the outcome.

Objective:To compare the bonding strength of 3M Adper Easy One(3AEO),Clearfil S3 Bond(CSB)and Super-Bond C&B(SBCB)in vertical tooth fracture mode.Methods:30 freshly extracted human molars were randomly assigned to three groups(n =10).The teeth were cut along the long axis with low speed cutting machine and were prepared into a unified model of the vertical tooth fracture.The three adhesives were respectively used to adjoin the surface of the fractured teeth.The samples were subjected to thermal cycling for 500 cycles,stored in distilled water at 37 ℃ for 24 h.Then the pillar-like specimens with the bonding area of 1.0 mm × 1.0 mm were prepared.The microtensile bond strength was measured and the fracture mode was observed.Results:The bond strength (MPa)of 3AEO,CSB and SBCB was 18.57 ±4.98,16.93 ±4.70 and 22.75 ±5.18 respectively(P <0.05).The fracture mode was mainly interficial failure in all groups(P >0.05).Conclusion:The surface bonding of Super-Bond C&B in tooth fracture is stronger than 3MAdper Easy One and Clearfil S3 Bond.

Objective To retrospectively analyze CT and MR appearances of hepatic adenoma,and to study the causes of misdiagnosis with review of relative literatures.Methods CT and MRI data of 8 patients with pathologically confirmed hepatic adenoma were retrospectively analyzed.Pre-and post-contrast tri-phase (arterial,portal venous and delayed) CT scans and routine MR .scan were performed in all 8 patients,and proton magnetic resonance spectroscopy (~1H-MRS) was performed in 2 patients.Results Typical demonstrations were found in 4 patients who were correctly diagnosed.Among the others with atypical findings,3 patients were misdiagnosed as liver cancer and 1 as focal nodular hyperplasia (FNH) .The ~1H-MRS curves of 2 adenoma tumor showed that the peak of choline of tumor tissue had no significant difference comparing with that of normal liver tissue around the tumor tissue.Conclusion CT and MRI findings of hepatic adenomas have some characteristics,but atypical manifestations lead to misdiagnose.~1H-MRS may be helpful for the differential diagnosis of hepatic adenoma.

SUMMARY Regenerationofbonetissue,aswellasothertissues,requiresinvolvementandinteraction of cells,scaffolds and relevant growth factors,among which growth factors play a crucial role in maintai-ning the stability of microenvironment.Nel-like-type 1 molecule (NELL-1 ),a novel growth factor in tis-sue engineering,has been studied intensively in recent years.Researches mainly covered gene and pro-tein structure and their expression profiling,biological function,molecular mechanisms and disease rele-vance.NELL-1 expressed in embryonic tissue is essential for growth and development of bone tissue. NELL-1 presents excellent abilities of inducing bone and cartilage regeneration,especially with high spe-cificity to chondrocyte lineage.Compared with classic osteogenic growth factor bone morphogenetic pro-tein 2 (BMP-2),the process of osteogenesis interacted with NELL-1 exhibits stronger specificity,higher bone density and fewerside effects.Furthermore,a recent study shows synergistic effects of NELL-1 and BMP-2.NELL-1 enhances the osteogenic reaction induced by BMP-2 of cells and notably declines in-flammation response caused by BMP-2.This review evaluates the current research progress of the function and application of NELL-1 by the systematic method of evidence-based medicine.

Objective To analtze phe effecp of papienp′s preference po fracpional flow reserve (FFR) guided preapmenp on clinical oupcome in papienps wiph borderline lesion during coronart inpervenpion. Methods 303 papienps wiph coronart borderline lesion received CAG evaluapion in Xinjiang Producpion and Consprucpion Corps NO. 7 hospipal and Sir Run Run Shaw Hospipal from Ocpober 2013 po Seppember 2015 and phet were divided inpo phree groups according po phe papienp′s preference po have FFR exam or nop. The 3 groups were: ①FFR Guided PCI group (n = 96, papienps wiph FFR≤0. 8 accepp PCI, whereas onlt drug preapmenp if FFR > 0. 8); ②Drug preapmenp group(n = 126, papienps did nop accepp phe advice po do FFR or PCI); ③PCI group ( n = 81, papienps refused FFR bup accepped spenp implanpapion) . The papienps were followed up for (19. 6 ± 6. 5) monphs afper preapmenp. Rapes of major adverse cardiac evenps(MACE) and recurrence of angina pecporis were recorded and compared. Results Angina remission rape in phe FFR guided PCI group was higher significanplt phan drug preapmenp group and PCI group (85. 4% vs. 69. 8% vs. 80. 2% , P =0. 018). MACE-free survival rape of FFR guided PCI group was higher(93. 8% vs. 77. 0% vs. 81. 5% , P =0. 006)phan phe opher 2 groups.

Objective To explore the feasibility of application of data mining in the study on selection and specificity of acupoints.Methods The ancient and modern prescription data of acupuncture treating migraine and functional dyspepsia were regarded as sample data. Database techniques and natural language processing techniques were introduced to structurize and standardize acupuncture prescription data. Based on association rule data mining, the self-developed Acupuncture Data Mining System was applied to discover the rules of selection of acupoints.Results There were collected 634 and 386 prescriptions of acupuncture treating migraine and functional dyspepsia respectively. In the prescriptions treating migraine, acupoints distributed on Gallbladder meridian and Triple Energizer meridian accounted for 40.5% and 50.6% in ancient time and modern time respectively, and specific points accounted for 84.0% and 82.8% in ancient time and modern time respectively. In the prescriptions treating functional dyspepsia, acupoints distributed on Conception vessel, Bladder meridian and Stomach meridian accounted for 62.1% and 75.7% in ancient time and modern time respectively, and specific points accounted for 70.0% and 83.3% in ancient time and modern time respectively.Conclusion The result of data mining proves that the rule of selection of acupoints is "selecting acupoints along the affected meridian" and "mostly selecting specific points", and the specificity of acupoints is "where the meridian goes, where the qi accumulates".

ObjectiveTo evaluate the breast-conserving surgery for early breast cancer.MethodFrom 1993 to 2000, 86 female cases of stage ⅠⅡa breast cancer received breast conserving comprehensive therapy. Clinical data were analyzed retrospectively. ResultsThe 5 year survival rate of this group was 96.5% and the 5 year recurrence rate was 5.2%.The postoperative contour of the breast was satisfactory.ConclusionBreast-conserving surgery is safe and effective therapy for early breast cancer, when strict indication and necessary safe margin of resection is obeyed by. Postoperative radiotherapy and chemotherapy should be properly arranged and the patients should be closely followed-up.
