Trans-ethnic analysis of susceptibility variants in IgA nephropathy / 北京大学学报(医学版)

OBJECTIVE@#To compare the genetic architecture of susceptibility variants of IgA nephropathy (IgAN) in Chinese and Europeans.@*METHODS@#We selected the independent genome-wide significant variants of IgAN in European population as candidate variants. Their associations, risk alleles, risk allele frequencies, odds ratios and population attributable risk scores were derived and calculated, then compared with those in the current Chinese population, including 1 194 IgAN patients and 902 controls. Using the significant variants, genetic risk scores were calculated and compared between the East Asians and the Europeans. The correlation between the genetic risk scores and clinical manifestations was also evaluated.@*RESULTS@#There were 16 independent single nucleotide polymorphisms (SNPs) located in 11 loci showing significantly association with susceptibility to IgAN in the Europeans. 93.75% (15/16) of them also showed significant associations in the Chinese (P<0.05). The effects of all the associated SNPs were in the same direction, either risk or being protective for IgAN, between the Chinese and the Europeans. On the contrary, remarkable higher risk allelic odds ratio (P=1.94×10-2), higher risk allele frequency (P=3.09×10-2), and higher population attributable risk (P=3.03×10-4) were observed for most of the associated SNPs in the Chinese than in the Europeans. Furthermore, genetic risk scores were significantly larger in the Asian populations compared with the Europeans (P=1.78×10-163). While there was no significance among the subpopulations in both the East Asians and the Europeans. Compared with the healthy controls, the genetic risk score in the IgAN patients was significantly larger (P=3.60×10-27). Clinical analysis showed the genetic risk score was positively associated with serum levels of IgA and IgA1, phases of chronic kidney disease and Haas grades.@*CONCLUSION@#Our study provides further evidence in the shared genetic architecture between Chinese and Europeans, while differences with respect to the effect sizes and risk allele frequencies across ethnicities, contributing partially to the differences of disease prevalence.

Development of laparoscopic technology in biliary surgery in the past 23 years: a single-center experience / 南方医科大学学报

<p><b>OBJECTIVE</b>To summarize the 23-year experience of laparoscopic biliary surgery in General Hospital of PLA and evaluate the application of laparoscopic surgery in the treatment of biliary diseases.</p><p><b>METHODS</b>We retrospectively analyzed the clinical data of 11 419 consecutive patients with biliary diseases undergoing laparoscopic surgery from April, 1992 and December, 2014. The disease spectrum was compared between patients treated before December 31, 2003 and those treated after the time point.</p><p><b>RESULTS</b>The 11419 patients receiving laparoscopic surgery accounted for 56.3% of the total patients undergoing biliary surgeries during the 23 years, including 4701 male and 6718 female patients with a mean age of 50.9∓13.2 years (6-93 years). Most (80.83%) of the patients received laparoscopic surgery for gallbladder stones, and 12.53% patients had the operation for gallbladder polyps. The laparoscopic operation rate was 84.81% in patients with gallbladder stones and 34.91% in patients with extrahepatic bile duct stones, but remained low in patients with biliary carcinoma. In laparoscopic operations, laparoscopic cholecystectomy was the most frequent (96.18%) followed by operations for extrahepatic bile duct stones, in which primary suture accounted for 1.38%, traditional T tube drainage for 0.90% and laparoscopic transcystic duct exploration for 0.72%. For malignant tumors, laparoscopic technique was used mainly for the purpose of exploration (0.34%). The application of laparoscopic technique in biliary surgery tended to increase after the year 2004, especially for benign gallbladder diseases and extrahepatic bile duct stones (P<0.05).</p><p><b>CONCLUSION</b>Laparoscopic technique in biliary surgery is gradually replacing the traditional open operation and becomes the gold standard for the treatment of benign biliary diseases.</p>

<p><b>OBJECTIVE</b>To discuss the impact of number of retrieved lymph nodes and lymph node ratio(LNR) on the prognosis in patients with stage II and III colorectal cancer.</p><p><b>METHODS</b>Clinicopathological data of 507 patients with stage II and III colorectal cancer were analyzed retrospectively. Follow-up was available in all the patients.</p><p><b>RESULTS</b>The total number of retrieved lymph nodes was 5801, of which 1122 had metastasis. There was a positive correlation between metastatic lymph nodes and retrieved lymph nodes(r=0.171, P<0.01). In stage II colorectal cancer there was a significant difference in 5-year survival rate between patients with more than 12 lymph nodes retrieved and those with less than 12 lymph nodes retrieved(P<0.01). LNR also affected the 5-year survival rate of patients with stage II and III colorectal cancer(P<0.05). In patients with similar LNR, the 5-year survival rate differed significantly among different regions of lymph node metastasis(P<0.05). LNR influenced the prognosis independent of the number of lymph nodes retrieved.</p><p><b>CONCLUSIONS</b>The number of retrieved lymph nodes is a prognostic factor for stage II and III colorectal cancer. More than 12 lymph nodes should be retrieved for better staging and prognosis. LNR is also a prognostic factor in stage II and III colorectal cancer. Regions of lymph nodes metastasis should be considered when evaluating the prognosis of patients using LNR.</p>
