Objective To study the serum laminin γ 2 monomer(LG2m),human circulating Gastrin(hPG80)in patients with hepatocellular carcinoma(HCC)and their clinical value.Methods 128 HCC patients admitted to the First People's Hospital of Shuangliu District from January 2016 to January 2018 were selected as the HCC group,70 patients with benign liver lesions diagnosed and treated at the same time were selected as the benign lesion group,and 70 healthy individuals who underwent physical examinations during the same time were selected as the control group.Use enzyme-linked immunosorbent assay to detect serum LG2m and hPG80 levels.The evaluation value of serum LG2m and hPG80 in predicting the prognosis of HCC patients were analyzed by receiver operating characteristic curve.Kaplan-Meier survival analysis was used to compare the survival prognosis of HCC patients with different serum LG2m and hPG80 levels.COX regression analysis was used to analyze the prognostic factors of HCC patients.Results The levels of serum LG2m(28.14±3.10 ng/L),hPG80(84.83±11.39 ng/L)in the HCC group were higher than those in the benign lesion group(9.18±1.74 ng/L,25.10±4.11 ng/L)and the control group(8.24±1.65 ng/L,23.15±3.26 ng/L),and the differences were statistically significant(t=68.240～76.635,all P＜0.05).The levels of serum LG2m and hPG80 in patients with TNM stage III,low differentiation degree,serum AFP＞400 μg/L were higher than those in TNM stage I to II,high differentiation,AFP≤400 μg/L,the differences were statistically significant(t=3.216～13.552,all P＜0.05).The area under the curve(95%CI)of the combined evaluation of serum LG2m and hPG80 for the prognosis of HCC patients was 0.934(0.889～0.961),which was greater than the single indicator of 0.813(0.774～0.849)and 0.896(0.840～0.937).The overall 5-year survival rates of HCC patients with high and low serum LG2m expression were 33.33%(21/63)and 67.69%(44/65),respectively.Compared with HCC patients with low expression of serum LG2m,HCC patients with high expression of serum LG2m had a lower 5-year cumulative survival rate(Log-Rankχ2=19.522,P＜0.05).The overall 5-year survival rates of HCC patients with high and low serum hPG80 expression were 35.48%(22/62)and 65.15%(43/66),respectively.Compared with HCC patients with low serum hPG80 expression,HCC patients with high serum hPG80 expression had a lower 5-year cumulative survival rate(Log-Rankχ2=12.546,P＜0.05).TNM stage III(OR=1.487,P＜0.05),low differentiation degree(OR=1.611,P＜0.05),serum AFP≥400μg/L(OR=1.416,P＜0.05),high expression of serum LG2m(OR=1.838,P＜0.05),and high expression of hPG80(OR=1.735,P＜0.05)were independent risk factors for poor prognosis in HCC patients.Conclusion The serum levels of LG2m and hPG80 in HCC patients increase,which are related to TNM staging,tumor differentiation,and serum AFP levels.They are serum biomarkers for evaluating the survival and prognosis of HCC patients.

Objective:To combine and improve two kinds of classical transvaginal cervical cerclage,and to provide a new reference for the clinical treatment of patients with cervical insufficiency(CIC).Methods:Retro-spective analysis was performed on the clinical data of 117 patients who underwent transvaginal cervical cerclage due to CIC from January 1,2018 to August 31,2023 in the Second Affiliated Hospital of Kunming Medical Univer-sity.According to different surgical methods,the patients were divided into the modified cerclage group(40 ca-ses),the McDonald cerclage group(40 cases)and the Shirodkar cerclage group(37 cases).Intraoperative and postoperative conditions and pregnancy outcomes were compared.Univariate and multivariate Logistic regression analysis was performed to analyze the related factors of preterm birth after modified cervical cerclage and the oth-er two groups of classical cervical cerclage.Results:①Compared with the McDonald cerclage group,the modified cerclage group had longer effective cervical length,longer delivery and gestational weeks,higher term delivery rate,and shorter post-operative contraction inhibitor time,with statistical significance(P＜0.05).Compared with the Shirodkar cerclage group,the operation time of patients in the modified cerclage was significantly shortened,the amount of intraoperative blood loss was reduced,the use time of postoperative contraction inhibitors was shortened,and the rate of postoperative wire-cutting was decreased,with statistical significance(P＜0.05).②Multivariate Logistic regression analysis of preterm birth showed that the longer the length of the cervix and the later gestational age when the modified cervical cerclage was performed with reference to McDonald's cerclage,the longer the length of the cervix after surgery,the later the gestational age when the suture was removed.The risk of preterm birth was reduced(OR＜1,P＜0.05),while preoperative BMI≥24 kg/m2 was associated with an increased risk of preterm birth(OR＞1,P＜0.05).Using Shirodkar's cerclage as reference,the risk of preterm delivery was consistent between the two types of cervix(P＞0.05).Longer cervical length and later gestational age after suture removal reduced the risk of preterm delivery(OR＜1,P＜0.05).Conclusions:The modified transvaginal cervical cerclage is simple and safe in clinical application,it has certain advantages in improving ad-verse pregnancy outcomes of pregnant women,which provides a new reference for the treatment of pregnant women with CIC.Due to the small number of cases included in the study,comprehensive evaluation by clinicians is still needed for clinical application.

ObjectiveTo compare the efficacy between the Mycob.T scanner system and manual microscopy for detecting acid-fast bacilli in sputum specimens. MethodsBetween January and November 2020， a total of 1 519 sputum samples from suspected primary tuberculosis patients from 5 designated tuberculosis hospitals in Shanghai were examined by Smear and BACTEC MGIT 960 liquid culture （liquid culture） methods. Each specimen was subiected to 2 direct smear slides. One slide was stained by Z-N method and examined with manual microscopic method. Another slide was stained and scanned by the Mycob.T system. The efficacy of manual microscopy and the Mycob.T scanner system for detecting acid-fast bacilli in sputum specimens was compared based on the result of liquid culture. Results of the repetitive scanning by the Mycob.T scanner system and the recheck of the manual microscopy were analyzed. ResultsThe average positive rate by the Mycob.T scanner system was 14.4% （219/1 519） while the average positive rate by manual microscopy was 16.3% （248/1 519）. No significant difference was observed （χ²=2.13， P=0.145）. Based on liquid culture confirmation results， the sensitivity of manual microscopy （60.36%） was higher than that of the Mycob.T scanner system （52.94%）， and the difference is statistically significant （χ²=4.38， P=0.036）. Both methods had high specificity （98.94%）. The concordance of the Mycob.T scanner system and manual microscopy was 95.46%， with the kappa value of 0.826. The results of repeatability test of the Mycob.T scanner system and the recheck results of the manual microscopy showed that the coincidence rate of scanning by the Mycob.T scanner system was 99.5% （436/438）， and the recheck coincidence rate by the manual microscopy was 98.6% （432/438）. ConclusionThe Mycob.T scanner system have high specificity for detecting acid-fast bacilli in sputum samples and good consistency with the results of manual microscopy. Compared with manual microscopic examination， the Mycob.T scanner system can greatly alleviate the work intensity.
