ObjectiveTo explore the correlation between the degree of liver damage and clinical manifestations in patients with pulmonary tuberculosis after chemotherapy. MethodsThis study included 3620 new smear-positive pulmonary tuberculosis patients treated with first-line anti-tuberculosis drug in the Second Central Hospital of Baoding from January 2008 to January 2014, and the follow-up study was carried out to observe medication use and side effects of anti-tuberculosis drug treatment. Comparison of categorical data was made by chisquare test. ResultsA total of 1225 patients (33.8%) exhibited clinical manifestations related to liver injury. The most common clinical manifestation was nausea and vomiting (72.9%), followed by fatigue (37.8%), rash (31.5%), abdominal distension and diarrhea (281%), fever (14.2%), anorexia (3.8%), and other manifestations (2.0%). The nausea and vomiting usually first appeared and were followed by abdominal distension and diarrhea. Of all patients, 243 cases (6.7%) suffered from liver damage and 109 cases (3.0%) had moderate to severe liver damage. Of the patients with clinical manifestations, 171 cases (14.0%) had liver damage and 74 cases(60%) suffered from moderate to severe liver damage. Compared with the patients without clinical manifestations, the relative risks of liver damage and moderate to severe liver damage were 4.643 [95% confidence interval (CI)=3.035-4.856] and 4.134 (95% CI=2.817-4.351), respectively, in the patients with clinical manifestations. The patients with fatigue, nausea and vomiting, rash, abdominal distension and diarrhea, anorexia, and other manifestations had higher risk of liver damage and moderate to severe liver damage than those without clinical manifestations (P<0.05) and the patients with anorexia showed the highest risk. ConclusionOne third of patients with pulmonary tuberculosis have liver injury-related clinical manifestations after chemotherapy. Patients with fatigue, nausea and vomiting, rash, abdominal distension and diarrhea, anorexia, and other manifestations are more susceptible to liver damage and moderate to severe liver damage.

Objective:To explore the differences in tumor-specific growth factors, cellular immune function and efficacy of olaparib and platinum-containing regimen for treatment of platinum-sensitive relapsed ovarian cancer patients with BRCA mutation.Methods:A retrospective cohort study was conducted. A total of 100 platinum-sensitive relapsed BRCA-mutant ovarian cancer patients in Baoding Second Central Hospital from September 2017 to March 2020 were retrospectively selected. The clinical data of the patients were analyzed, and they were divided into the olaparib group (treated with olaparib tablets) and the platinum-containing regimen group (treated with paclitaxel and platinum drugs for 6 cycles, followed by olaparib tablets maintenance therapy), with 50 patients in each group. The clinical efficacy, tumor specific growth factor [carbohydrate antigen (CA) 125, CA199, human epididymal protein 4 (HE4)] levels, cellular immune function-related indicators [T-cell subsets (proportions of CD3 + cells and CD4 + cells), CD4 + cells/CD8 + cells ratio (CD4 +/CD8 +)], and quality of life scores before treatment and after 2, 4 and 6 cycles of treatment of the two groups were compared, as well as the safety of the two groups. The data of three years of follow-up were obtained, Kaplan-Meier method was used to analyze the progression-free survival (PFS) of patients in the two groups, and log-rank test was used for comparison between groups. Results:The age of patients in the olaparib and platinum-containing regimen groups was (53±7) years old and (56±7) years old, respectively. The differences in compositions of patients with different age, body mass index, Eastern Cooperative Oncology Group (ECOG) performance status score, primary tumor location, lesion size, pathological stage, pathological type, germline BRCA mutation, and previous chemotherapy response between the two groups were not statistically significant (all P > 0.05). The objective response rate (ORR) [58.0% (29/50) vs. 38.0% (19/50)] and disease control rate (DCR) [80.0% (40/50) vs. 56.0% (28/50)] of the olaparib group after treatment were higher than those of the platinum-containing regimen group, and the differences were statistically significant (both P < 0.05). Serum CA125, CA199 and HE4 levels were gradually decreased in both groups before treatment and after 2, 4 and 6 cycles of treatment (all P < 0.05); serum CA125, CA199 and HE4 levels in the olaparib group after 2, 4 and 6 cycles of treatment were lower than those in the platinum-containing regimen group, and the differences were statistically significant (all P < 0.05). The CD3 + cells ratio, CD4 + cell ratio and CD4 +/CD8 + in the olaparib group gradually increased before treatment and after 2, 4 and 6 cycles of treatment (all P < 0.05), while those in the platinum-containing regimen group all gradually decreased (all P < 0.05); the CD3 + cells ratio, CD4 + cells ratio and CD4 +/CD8 + in the olaparib group were higher than those in the platinum-containing regimen group after 2, 4 and 6 cycles of treatment, and the differences were statistically significant (all P < 0.05). The quality of life scores of both groups increased before treatment and after 2, 4 and 6 cycles of treatment (all P < 0.05), and the quality of life scores of the olaparib group were higher than those of the platinum-containing regimen group after 2, 4 and 6 cycles of treatment, and the differences were statistically significant (all P < 0.05). The incidence of nausea, fatigue and malaise, vomiting, anemia, and diarrhea at all levels in the olaparib group was lower than those in the platinum-containing regimen group (all P < 0.05). By follow-up for 3 years, there was no statistically significant difference in PFS between the olaparib group and the platinum-containing regimen group ( P > 0.05). Conclusions:The efficacy of olaparib treatment in platinum-sensitive relapsed ovarian cancer patients with BRCA mutation is superior to platinum-containing regimen, and it can increase the level of T cells, inhibit the expression of tumor-specific growth factors, improve the quality of life, and have a positive effect on improving the safety of treatment.
