ABSTRACT

Objective:To investigate the therapeutic efficacy and prognosis of multiple myeloma (MM) patients with early relapse and the influencing factors of early relapse.Methods:The clinical data of 164 patients with newly diagnosed MM admitted to Affiliated Hospital of Hebei University from January 2018 to January 2021 were retrospectively analyzed, and 53 cases (32.3%) relapsed at the end of the follow-up. According to the recurrence within 12 months or not, the patients were divided into early relapse group and advanced relapse group; the clinical characteristics, overall response rate (ORR) and overall survival (OS) of both groups were compared. Logistic regression was used to analyze if the following indexes including age, gender, albumin, lactate dehydrogenase (LDH), β 2-microglobulin (β 2-MG), hemoglobin, creatinine, serum calcium, bone marrow plasma cell ratio, extramedullary disease, high-risk fluorescent in situ hybridization (FISH) were the influencing factors of the early relapse. Based on 7 published clinical trials, simplified early relapse MM (S-ERMM) scoring system was constructed to subgroup all relapsed patients. The difference in risk stratification between early relapsed patients and advanced relapsed patients was compared. Results:The median follow-up time of 164 newly diagnosed MM patients was 26 months (12-48 months). Among 53 relapsed MM patients, 24 cases had early relapse and 29 cases had advanced relapse. The ORR of patients with early relapse was decreased compared with that of those with advanced relapse [70.8% (17/24) vs. 89.7% (26/29), χ2 = 3.04, P = 0.001]. The median OS of the early relapse group was shorter than that of the advanced relapse group (24 months vs. not reached, P < 0.001). The OS of patient in the early relapse group with the best response ≥ complete remission (CR), ≥ very good partial remission (VGPR) and ≥ partial remission (PR) during initial induction therapy was worse than that of those in the advanced relapse group, and the differences were statistically significant ( P values were 0.008, 0.011, 0.012, respectively). Multivariate Logistic regression analysis showed low albumin (<35 g/L vs. ≥35 g/L: OR = 1.644, 95% CI 1.076-2.511, P = 0.022) and high LDH (< the upper limit of normal value vs. ≥ the upper limit of normal value: OR = 0.998, 95% CI 0.985-1.011, P = 0.030) were independent influencing factors of early relapse. Among 24 early relapse patients, there were 5 cases (20.8%), 13 cases (54.2%), 6 cases (25.0%), respectively in the S-ERMM scoring system low-risk, middle-risk, high-risk groups; among 29 advanced relapse patients, there were 18 cases (62.1%),9 cases (31.0%), 2 cases (6.9%), respectively in the S-ERMM scoring system low-risk, middle-risk, high-risk groups; the difference in risk stratification of the S-ERMM scoring system between the early relapse group and the advanced relapse group was statistically significant ( χ2 = 9.09, P = 0.003). Conclusions:MM patients with early relapse have poor therapeutic efficacy and prognosis. The prognosis is not affected by the depth of remission to first-line therapy. Low albumin and high LDH may be independent risk factors of MM patients with early relapse.

ABSTRACT

Objective:To examine the influence of hyperlipidemia on perioperative outcomes of rectal cancer patients.Methods:From June 2016 to June 2019, 86 patients who had received laparotomy or laparoscopic radical resection of rectal cancer at the Department of General Surgery of Nanjing Jiangbei People's Hospital were selected as research subjects.Preoperative blood lipids were measured.Based on lipid levels, patients were divided into the hyperlipidemia group(46 cases)and the normal blood lipid group(40 cases). Operative time, intraoperative blood loss, postoperative recovery outcomes, incidence of anastomotic fistula, and incidences of incision fat liquefaction and incision infections were compared between the two groups.SPSS21.0 was used for data analysis.Results:Compared with the normal lipid group, the operative time of the hyperlipidemia group was significantly longer and the amount of intraoperative blood loss was higher in the hyperlipidemia group, and the differences were statistically significant.Compared with the normal lipid group, the hyperlipidemia group showed a longer time to first postoperative flatus and to first postoperative oral intake, delayed drainage tube removal and ambulation, and longer hospital stays, with statistically significant differences.There were 17 cases of postoperative complications in the hyperlipidemia group(37.0%)and 4 cases in the normal lipid group(10.0%), and the difference was statistically significant( χ2=7.027, P=0.008). Conclusions:Hyperlipidemia has adverse effects on surgical outcomes and postoperative recovery for rectal cancer patients.

ABSTRACT

The development of gastritis is associated with an increased risk of gastric cancer. Current invasive gastritis diagnostic methods are not suitable for monitoring progress. In this work based on 78 gastritis patients and 50 healthy individuals, we observed that the variation of tongue-coating microbiota was associated with the occurrence and development of gastritis. Twenty-one microbial species were identified for differentiating tongue-coating microbiomes of gastritis and healthy individuals. Pathways such as microbial metabolism in diverse environments, biosynthesis of antibiotics and bacterial chemotaxis were up-regulated in gastritis patients. The abundance of Campylobacter concisus was found associated with the gastric precancerous cascade. Furthermore, Campylobacter concisus could be detected in tongue coating and gastric fluid in a validation cohort containing 38 gastritis patients. These observations provided biological evidence of tongue diagnosis in traditional Chinese medicine, and indicated that tongue-coating microbiome could be a potential non-invasive biomarker, which might be suitable for long-term monitoring of gastritis.

ABSTRACT

Objective To observe the effect of different explosion impulse on rabbit lung injury and decide the death curve,so as to provide a reference for the prediction of lung injury.Methods Six healthy male New Zealand white rabbits with weight of 2.0-2.5 kg and age of (6 ± 1)months were selected.The rabbits were put 0.5 m,0.6 m,0.7 m,0.9 m,1.0 m,and 1.2 m away from 90 g TNT to carry out the blast injury experiment.The characteristic parameters of blast shock wave and general lung injury were recorded.Based on the experimental results combined with theoretical analysis,the changes of rabbit lung injury depending on the explosion distance as well as the rabbit death curve were determined.Results After the 90 g TNT explosion,the peak overpressure of shock wave and the corresponding specific impulse decreased quickly with the increase of explosion distance.The peak overpressure was 0.79 MPa and the specific impulse was 82 Pa · s at the explosion distance of 0.5 m.The peak overpressure was 0.1 MPa and the specific impulse was 34 Pa · s at the explosion distance of 1.2 m.The rabbits at 0.5 m and 0.6 m died,the rabbit at 0.7 m was severely injured,and the rabbits at 0.9 m,1.0 m,and 1.2 m were slightly injured.The dependence of lung injury degree on the explosion distance under 90 g TNT explosion was established based on dimensional analysis theory.The lung injury degree was exponentially attenuated with the explosion distance:φ =(R/0.6)-5.64(φ represented lung injury degree,and R represented the explosion distance).Considering the combined injury effects of peak overpressure of shock wave and its specific impulse on rabbit lung,the death curve of rabbit was determined:(p-0.1) (I-59) =2.6 (p represented peak overpressure,and I represented specific impulse).The criterion of "overpressure-specific impulse" was used to estimate the death of rabbit,and the death curve of rabbit was determined as (p-0.1)(I-59) =2.6(p represented peak overpressure and I represented specific impulse).The critical overpressure was 0.1 MPa and the critical specific impulse was 59 Pa · s.Conclusions Under the explosion condition of 90 g TNT,the relationship between degree of lung injury in rabbits and explosion distance is established.Death curve of rabbits is determined based on the damage effect of shock wave peak overpressure and specific impulse on the lungs of rabbits,which is significant for predicting the blast injury.
