AIM To evaluate the short-term and long-term outcomes following laparoscopic vs open surgery for pathological T4(pT 4) colorectal cancer.METHODS We retrospectively analyzed the short-and long-term outcomes of proven p T4 colorectal cancer patients who underwent complete resection by laparoscopic or open surgery from 2006 to 2015 at Guangdong General Hospital.RESULTS A total of 211 p T4 colorectal cancer patients were included in this analysis, including 101 cases in thelaparoscopy(LAP) group and 110 cases in the open surgery(OPEN) group [including 15(12.9%) cases of conversion to open surgery]. Clinical information(age, gender, body mass index, comorbidities, American Society of Anesthesiologists score, etc.) did not differ between the two groups. In terms of blood loss, postoperative complications and rate of recovery, the LAP group performed significantly more favorably(P < 0.05). With regard to p T4 a/b and combined organ resection, there were significantly more cases in the OPEN group(P < 0.05). The 3-and 5-year overall survival rates were 74.9% and 60.5%, respectively, for the LAP group and 62.4% and 46.5%, respectively, for the OPEN group(P = 0.060). The 3-and 5-year disease-free survival rates were 68.0% and 57.3%, respectively, for the LAP group and 55.8% and 39.8%, respectively, for the OPEN group(P = 0.053). Multivariate analysis showed that ⅢB/ⅢC stage, lymph node status, and CA19-9 were significant predictors of overall survival. PT4 a/b, ⅢC stage, histological subtypes, CA19-9, and adjuvant chemotherapy were independent factors affecting disease-free survival.CONCLUSION Laparoscopy is safely used in the treatment of p T4 colorectal cancer while offering advantages of minimal invasiveness and faster recovery. Laparoscopy is able to achieve good oncologic outcomes similar to those of open surgery. We recommend that laparoscopy be carried out in experienced centers. It is still required to screen the appropriate cases for laparoscopic surgery, optimize the preoperative diagnosis process, and reduce the conversion rate. Multi-center, prospective, and large-sample studies are required to assess these issues. 展开更多

Objective Population genetic analysis based on genetic markers harbors valuable forensic applications.In this regard,it is informative and imperative to explore Han groups as they are the largest population of China.In particular,there is a largely underrepresented amount of information from recent decades regarding the southeast costal Han Chinese.Therefore,the aim of this study is to investigate the available genetic characteristics of the Han population living in the Jinjiang,Fujian Province,Southeastern China.Methods We sampled 858 saliva samples and used the commercially available Microreader^(TM) Y Prime Plus ID System to identify population data of Y-short tandem repeat(STR)loci of this region.Results A total of 822 different haplotypes were observed.The overall haplotype diversity,discriminatory power and haplotype match probability were 0.9999,0.9999 and 0.0012,respectively.Conclusion Our results showed that the Jinjiang Han population was closely genetically related to Han groups of China.Overall,we identified a set of 37 Y-STRs that are highly polymorphic,and that can provide meaningful information in forensic practice and human genetic research. 展开更多
