Objective To investigate the predictive value of serum interleukin-17(IL-17)and soluble hemoglobin scavenger receptor 163(sCD163)for early anastomotic leakage in patients with colorectal cancer after laparoscopic surgery.Methods From June 2022 to June 2024,80 colorectal cancer patients who underwent laparoscopic surgery were selected as the study subjects.Patients were subdivided into an anastomotic leakage group(17 cases)and a non-anastomotic leakage group(63 cases)according to whether an anastomotic leakage occurred within 7 d postoperatively.Enzyme-linked immunosorbent assay(ELISA)was applied to detect the levels of serum IL-17 and sCD163 in patients on preoperative day 1,postoperative day 1,postoperative day 3,postoperative day 5,and postoperative day 7.The clinical data of the two groups were compared.Multivariate Logistic regression was applied to analyze the influencing factors of early anastomotic leakage in colorectal cancer patients after laparoscopic surgery.The receiver operating characteristic curve(ROC curve)was applied to analyze the predictive value of serum IL-17 and sCD163 levels for early anastomotic leakage in colorectal cancer patients after laparoscopic surgery.Results The percentage of distance between tumor and anus＜7 cm was higher in the anastomotic leakage group than that in the non-anastomotic leakage group,and the amount of drainage was more than that in the non-anastomotic leakage group at 7 d postoperatively,the differences were statistically significant(P＜0.05).There were statistically significant differences in the levels of serum IL-17 and sCD163 between the two groups of patients at different time points,as well as in time and interaction effects(P＜0.05).Distance between tumor and anus＜7 cm(O R=3.176,95％CI:1.128～8.940),serum IL-17 level ≥ 43.95 pg/mL at 3 d postoperatively(O R=2.145,95％CI:1.281～3.592),and serum sCD163 level ≥ 81.02 pg/mL at 5d postoperatively(OR=1.852,95％CI:1.225～2.801)were the risk factors of early anastomotic leakage in patients with colorectal cancer after laparoscopic surgery(P＜0.05).The area under the curve(AUC)of the combination of serum IL-17 and sCD163 in predicting early anastomotic leakage in colorectal cancer patients after laparoscopic surgery was 0.923,which was superior to the single diagnosis of serum IL-17 and sCD163(Zcombination-IL-17=2.77,Zcombination-sCD163=2.11,P＜0.05).Conclusion Serum IL-17 and sCD163 levels are elevated in colorectal cancer patients with early anastomotic leakage after laparoscopic surgery.The combined detection of the two has certain clinical value in predicting early anastomotic leakage in patients with colorectal cancer after laparoscopic surgery.

Objective To observe the effects of Xifeng Tongnao capsules on the content of TNF-α and IL-1β in brain tissue of rats with focal cerebral ischemia-reperfusion injury. Methods A total of 120 adult SD rats were randomized into 6 groups: Xifeng Tongnao low-, middle- and high-dose groups, model control group, Buchang Naoxintong group and sham-operated group.Buchang Naoxintong group were treated with Buchang Naoxintong capsules at 0.864 g??kg-1.Xifeng Tongnao high-, middle-and low-dose groups were treated with 3.456, 1.728, and 0.864 g??kg-1 Xifeng Tongnao capsules, respectively;sham-operated group and model control group were treated with equal volume of purified water. Medications were administered intragastrically once daily for 7 days. The acute transient focal cerebral ischemia-reperfusion model was established by middle cerebral artery occlusion ( MCAO) 1 h after the final dose, and rats in the sham-operated group only received anesthesia and stripping without occlusion.All rats were sacrificed after reperfusion for 24 h, and expression levels of TNF-α and IL-1β in the brain tissue were detected by ELISA. Results TNF-αcontent in Xifeng Tongnao capsutes low-, middle-and high-dose groups were (35.34±8.95), (33.75±6.92), and (40.95±5.39) ng??L-1, respectively.IL-1β content were (1.44±0.47), (1.45± 0.23), and (1.61±0.33) ng??L-1 in low-, middle- and high-dose groups, respectively.TNF-α and IL-1β were (38.96±9.84) and (1.56±0.31) ng??L-1, respectively in Buchang Naoxintong group, (52.74±6.76) and (2.79±0.45) ng??L-1in the model control group, and (32.54±4.00) and (1.32±0.22) ng??L-1 in sham-operated group.TNF-αand IL-1βcontent were significantly higher in Buchang Naoxintong group than in sham-operated group ( P<0. 05 ) . TNF-α and IL-1β content were significantly decreased in Xifeng Tongnao high-, middle- and low-dose groups (all P<0.05). Conclusion Xifeng Tongnao capsules can protect brain tissue by supressing TNF-α and IL-1β and alleviating inflammatory injury from ischemia.

Objective To develop a convenient, rapid and specific method using real-time fluorescent quantitative polymerase chain reaction (FQ-PCR) for detection of facioscapulohumeral muscular dystrophy(FSHD). Methods Genomic DNA was extracted and digested by restricted endonuclease EcoR Ⅰ , followed by agarose electrophoresis. The DNA (< 38 kb) was retrieved from agarose electrophoretic gels. The primers and probe were designed in D4ZA gene in chromosome 4. One hundred and fifteen subjects were examined by FQ-PCR using the retrieved DNA (<38 kb) as a template and the result was analyzed by fluorescent curve comparing with positive control. Results The results by FQ-PCR showed that 13 cases were positive in 16 FSHD cases whose EcoR Ⅰ fragment sizes were known, 75 cases were negative in 78 cases of normal controls, 15 cases were positive in 16 FSHD cases diagnosed clinically whose EcoR Ⅰ fragment sizes were unknown, and 3 cases were positive in 5 cases of relatives of FSHD patients. Consistency was checked using Kappa index between the 2 gene diagnostic tests for FSHD (FQ-PCR test and the traditional Southern blotting test), and between the 2 diagnostic criterions (gene diagnosis by FQ-PCR and clinical diagnosis). The results were statistically significant (κ = 0. 765, P = 0. 002 ; κ = 0. 844, P = 0. 000). Conclusions A new genetic diagnostic method of FSHD by FQ-PCR was developed, which was more simplified and reliable compared to the time-consuming, radioactive Southern blotting. It could also detect the D4Z4 arrays in cases having deletion of p13E-11 as well as the interchromosomal exchange between 4q35 and 10q26. The new method of FQ-PCR for FSHD may be extended to utilize clinically in future.
