ABSTRACT
Objective:To explore the application of list nursing management combined with different artificial liver treatment modes in patients with liver failure.Methods:Fifty-three patients with liver failure hospitalized in Bethune Hospital of Shanxi Province from July 2020 to July 2021 were selected as the control group, 63 patients with liver failure hospitalized in Bethune Hospital of Shanxi Province from July 2021 to July 2022 were selected as the intervention group. According to the different treatment modes of artificial liver for patients, plasma exchange (PE), double plasma molecular adsorption system (DPMAS) and PE + DPMAS treatment were set up in the two groups. The control group received routine nursing care, while the intervention group received checklist nursing care in addition. The changes of albumin (ALB) and prothrombin time (PT) indexes before and after the different treatment modes were compared, together with the occurrence of complications between the two groups after the intervention.Results:The baseline data between the two groups was balanced, the difference had no statistical significant ( P>0.05). After the therapy, the level of ALB of patients who had accepted DPMAS and PE + DPMAS in the intervention group were 25.3(24.0, 27.9) and 23.2(22.4, 26.3) g/L, which were lower than the 28.2(26.3, 29.7) and 29.4(27.2, 30.0) g/L in the control group, the differences were significant ( Z = 2.47, 3.55, both P<0.05). After the therapy, the level of PT of patients in the intervention group under all three treatment modes were 15.8(14.8, 16.8), 22.7(19.2, 26.2) and 6.0(14.6, 20.0) s, which were lower than the 17.4(15.9, 20.9), 26.3(21.4, 36.4) and 21.2(16.9, 23.4) s in the control group, the differences were significant ( Z = 2.10, 2.07, 2.21, all P<0.05). In the intervention group, there were 6 cases of hypotension, anaphylaxis, bleeding, coagulation and infection under the DPMAS treatment mode, which was significant lower than the 11 cases in the control group ( χ2 = 4.97, P<0.05). There were 4 cases in the intervention group with the PE + DPMAS treatment mode occurred complications in above, which were significant lower than the 11 cases in the control group ( χ2 = 6.87, P<0.01). Conclusions:Artificial liver treatment can improve patients′ liver function and coagulation, and list nursing management may help to improve the effect of artificial liver treatment. It can improve nurses′ awareness of risk prejudgement, reduce various risks in the treatment process, reduce the incidence of adverse reactions, and enhance health care and patient satisfaction.
ABSTRACT
ObjectiveTo observe the regulation of Qigongwan on the expression of proliferation and apoptosis-related factors programmed cell death 4 （PDCD4） and proliferating cell nuclear antigen （PCNA） in ovarian granulosa cells （GCs） in patients with polycystie ovarian syndrome （PCOS） infertility with phlegm-dampness syndrome， and to explore the effect of Qigongwan on the quality of oocytes and embryonic development potential. MethodSixty-six patients with PCOS with phlegm-dampness syndrome who underwent in vitro fertilization and embryo transfer （IVF-ET） were randomly selected and divided into an observation group （Qigongwan + western medicine） and a control group （western medicine）， with 33 patients in each group. Antagonist regimen was used to promote ovulation in the two groups. The observation group was given Qigongwan one cycle before IVF based on the treatment of conventional western medicine， while the control group was not given Chinese medicine. The improvement of phlegm and dampness syndrome， the dosage and the number of days of using gonadotropins （Gn）， the levels of luteinizing hormone （LH）， estradiol （E2）， and progesterone （P） on the day of human chorionic gonadotropin（HCG） injection， the 2PN fertilization rate， and the high-quality embryo rate of patients in the two groups were compared. Real-time polymerase chain reaction （Real-time PCR） and Western blot technology were used to detect the expression of PCNA and PDCD4 in GCs. ResultAs compared with groups before treatment， the score of phlegm-dampness syndrome in both groups was significantly lower （P<0.01）. The score of phlegm and dampness syndrome in the observation group was significantly lower than that of the control group （P<0.01）. As compared with the control group， the levels of LH， E2， and P in the observation group was higher， but only the difference in the level of E2 was statistically significant （P<0.01）. The 2PN fertilization rate ［82.25% （556/676） vs 69.92% （365/522）， χ2=25.172， P<0.01］ and high-quality embryo rate ［44.19% （190/430） vs 34.23% （102/298）， χ2=7.266， P<0.01］ in the observation group were significantly higher than that of the control group （P<0.01）. As compared with the control group， the mRNA and protein expression of PDCD4 in ovarian GCs was down-regulated in the observation group and that of PCNA was up-regulated （P<0.05）. ConclusionBy down-regulating the expression of PDCD4 and up-regulating the expression of PCNA， Qigongwan may interfere with follicle development， adjust hormone levels， improve the symptomatic manifestations of patients with PCOS with phlegm-dampness syndrome， inhibit the apoptosis of GCs， and promote growth， thus improving the quality of oocytes and embryonic development potential.
ABSTRACT
Objective:Explore the predictive value of body composition and related factors in early detection of gestational diabetes mellitus (GDM).Methods:949 pregnant women (142 cases in GDM group and 807 cases in normal group) in early pregnancy were selected from March 2019 to March 2020 in Suzhou Municipal Hospital, subject's clinical data were recorded. Body composition was measured by bioelectrical impedance method before the 13th week of pregnancy, and the relationship between age, protein, basal metabolic rate, body mass index (BMI) before pregnancy, body fat percentage, fat mass index (FMI), pregnancy times and the screening results of glucose tolerance in the second trimester of pregnancy were analyzed. The risk factors of GDM were further identified by multivariate regression analysis. Finally, the ROC curve was drawn to determine the diagnostic value of GDM, and the best boundary value was found to calculate the sensitivity and specificity of the indicators.Results:The age (20.82±2.60 vs 22.35±3.64), BMI before pregnancy (20.82±2.60 vs 22.35±3.64), percentage of body fat (29.37±5.63 vs 32.14±5.77), FMI [6.06(5.00, 7.30) vs 6.87(5.60, 8.60)] and pregnancy times [1(1, 2)vs 2(2, 3)] in GDM group were higher than those in normal group. Pregnancy times ( OR=1.232, 95% CI: 1.033-1.471) and FMI ( OR=1.228, 95% CI: 1.057-1.426) are independent risk factors of GDM. When FMI was used to predict the incidence of GDM, the area under the curve (AUC) was 63.0%. Conclusion:Pregnancy times and FMI in early pregnancy can be used as independent predictors of GDM. They provide a basis for scientific adjustment of diet and reasonable exercise, thereby preventing the GDM as early as possible. FMI can be reduced by adjusting the dietary structure and engaging in reasonable exercise, to reduce its risk among pregnant women.
ABSTRACT
Coronary artery disease (CAD) is a chronic disease but causes the highest mortality and morbidity among the cardiovascular diseases worldwide. Correlations between CAD and gut microbiota have been observed. This suggests that the gut microbiota could become a vital diagnostic marker of CAD, and restoring the gut habitat may become a promising strategy for CAD therapy. The elevated level of trimethylamine-N-oxide (TMAO), a gut microbiota-derived metabolite, was found to be associated with the increased risk of cardiovascular disease and the all-cause mortality. Preclinical studies have shown that it has pro-arteriosclerosis properties. It is likely that regulating the production of TMAO by gut microbiota may become a promising strategy for anti-atherosclerosis therapy. This review summarizes the clinical and preclinical researches on the intervention of CAD by regulating the gut microbiota and the microbiota-derived metabolite TMAO, with the aim to provide new target for the therapy of CAD.

ABSTRACT
Objective@#To explore the effect of enterostomy on analgesic pattern in advanced digestive tract cancer.@*Methods@#A retrospective cohort study was carried out, which was approved by the Ethics Committee of the Sixth Affiliated Hospital of Sun Yat-sen University (E2018026). Inclusion criteria were as follows: (1)age and gender were not limited; (2) all the gastrointestinal malignancies were confirmed histologically, and local recurrence or metastasis were confirmed by CT or MR; (3) numerical rating scale (NRS) ≥4 points, opioid analgesic drugs were required; (4) informed consents were signed by patients of their own. Exclusion criteria were as follows: (1) malignancies of early stage; (2) suspicious adverse mental states which might lead to poor administration compliance; (3) hypersensitivity or allergic reactions to opioids. Clinical data of patients with advanced gastrointestinal cancer receiving comprehensive treatment at the Medical Oncology Department of the Sixth Affiliated Hospital of Sun Yat-sen University from September 2016 to April 2017 were retrospectively collected. The patients were divided into the stoma group and the non-stoma group. The clinical findings of two groups were analyzed, including age, sex, ostomy status, pain location, presence or absence of intestinal obstruction, pain characteristics, selection of opioid analgesic agents, treatment of side effects of analgesics. Pain was assessed using brief pain inventory(BPI) table and NRS score. Strong opioids were prescribed for patients of NRS ≥4. Patients who were intolerant to opioids required opioid titration. The titration drugs included oral or IV morphine and oxycodone. After achievement of adequate pain control, long-acting opioids were administered, which included sustained-release morphine tablets, controlled release oxycodone and transdermal fentanyl. Criteria for pain relief included NRS≤3, breakthrough pain <3 times/day and duration of adequate pain control >3 days. The χ2 test and the Wilcoxon signed rank sum test (nonparametric test) were used to analyze the clinical features of patients in the stoma and non-stomach groups. In order to find the factors associated with maintenance therapy and the use of laxatives, the variables were compared as well as in multivariate analysis with multiple regression models. For all the statistical tests, a value of P<0.05 in a two-tailed test was established as the alpha significance level.@*Result@#A total of 123 patients were enrolled in this study, including 79 males (64.2%) and 44 females (35.8%) with a median age of 51 years. Fifty-two patients were in stoma group, including 30 (24.4%) of ileostomy and 22 (17.9%) of colostomy, and 71 patients were in non-stoma group. Pain of 40 (76.9%) patients in stoma group located in abdomenopelvic site while the pain of 44 (62.0%) patients in non-stoma group located in other sites. Compared with non-stoma group, cases in stoma group complained more abdominopelvic pain (73% vs. 62.0%, P<0.001).The median NRS pain score before treatment in the stoma group and the non-stoma group was 5.7 and 5.6, respectively, without statistically significant difference (P=0.741). After analgesic management, the above scores reduced to 2.1 and 2.3, respectively, without statistically significant difference as well (P=0.092). Analgesic treatment was effective in 111 cases (90.2%), including 49 cases (94.2%) in the stoma group, and 62 cases (87.3%) in the non-stoma group, and there was no statistically significant difference between the two groups (P=0.202). There was more application of fentanyl transdermal patch [34.6%(18/52) vs. 9.8%(7/71)] in the stoma group, while more application of lactulose laxative [78.9%(56/71) vs. 61.5%(32/52)](χ2=10.023, P=0.002) in the non-stoma group. Multivariate analysis revealed that ostomy (OR=0.290, 95%CI: 0.102-0.824, P=0.009) and pain site (OR=5.691, 95%CI:1.709-18.948, P=0.005) were independent factors affecting the choice of the first line opioid sustained release agent. Of the 123 patients with maintaining analgesia, 98 had available data of laxative use, of whom 46 used laxatives to prevent or treat constipation, and the proportion of laxatives in stoma group (21.2%, 11/52) was significantly lower than that in non-stoma group (49.3%, 35/71) (χ2=6.957, P=0.008). Multivariate analysis of the application of laxative use showed that age (OR=0.281, 95% CI: 0.123-0.684, P=0.010) and ostomy (OR=2.621, 95% CI: 1.033-6.687, P=0.045) were independent factors affecting the use of lactulose laxatives.@*Conclusions@#Enterostomy may affect the analgesic pattern in advanced digestive tract cancer. Patients with stoma are more likely to use fentanyl transdermal patches and younger patients with stoma do not need prophylactic use of laxatives.
ABSTRACT
Objective To explore the significance of the cut point of peak level of luteinizing hormone (LH) in gonadotropin-releasing hormone (GnRH) agonist test in the diagnosis of precocious puberty in obese girls.Methods According to the diagnostic criteria of children's central precocious puberty diagnosis consensus (2015),796 cases of precocious puberty (peak level of LH ≥3.3 IU/L) in Children's Hospital of Zhejiang University School of Medicine from January 2014 to December 2015 were divided into normal weight group (573 cases),overweight group (170 cases) and obesity group (53 cases).The 3 groups were compared in terms of basic level of LH,basic level of follicle stimulating hormone (FSH),peak level of LH and FSH,ratio of LH (peak)/FSH (peak),sex hormone binding protein (SHBG),and children with 3.3 IU/L ≤peak level of LH ＜5.0 IU/L were followed up.The accuracy of the diagnosis of central precocious puberty using peak level of LH was analyzed by using receiver operating characteristic (ROC) curve.Results The median of LH (peak) in the obese group was 6.92 IU/L,the median of SHBG was 46.52 nmol/L,the median of LH (peak) in normal weight group was 8.92 IU/L,and the median of SHBG was 87.28 nmol/L.There were significant differences between the 2 groups (P ＜ 0.05,0.001).A total of 89 cases in normal weight group and 65 cases of obesity/overweight group (3.3 IU/L ≤peak level of LH ＜5.0 IU/L) were followed up for 1 year,and 18 cases in normal weight group and 33 cases in obesity/overweight group developed to central precocious puberty,while the number of cases in the 2 groups was significantly different (P ＜0.001).The ROC curve analysis showed that the cut point of peak level of LH was 4.16 IU/L,the sensitivity was 0.606,the specificity was 0.656,and the Jordan index was the largest (0.344).Conclusions The peak level of LH in GnRH agonist test is important for the diagnosis of central precocious puberty in girls,but the effect of body mass index on its cut point needs to be considered.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the safety and preliminary efficacy of dose-modified regimen of 5-fluorouracil plus oxaliplatin and irinotecan (mFOLFOXIRI) for patients with advanced colorectal cancer (CRC).</p><p><b>METHODS</b>Data of 312 CRC patients confirmed by pathology receiving triplet drug alone or combined with target therapy between October 2012 and December 2016 at the Sixth Affiliated Hospital of Sun Yat-sen University were retrospectively analyzed. CRC patients who had previously completed adjuvant therapy (or neoadjuvant therapy) within 6 months or palliative chemotherapy were excluded, meanwhile those with poor general condition (ECOG score > 2) or grade 2 neuropathy and allergy to oxaliplatin were excluded as well. Regimen of mFOLFOXIRI: oxaliplatin 85 mg/m² dissolved in 5% glucose solution 500 ml by intravenous infusion for 2 h; irinotecan 150 to 165 mg/m² dissolved in 0.9% sodium chloride 250 ml by intravenous infusion for 90 min; following intravenous infusion of leucovorin 400 mg/m² for 2 h, day 1; 5-FU 2800 mg/m², 48-h continuous intravenous infusion; once every 2 weeks. Therapy could be combined with a targeted drug, bevacizumab 5 mg/kg every two weeks; cetuximab 500 mg/m² every two weeks. Side effect was graded using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE 4.0.3). The objective response rate was evaluated according to the Response Evaluation Criteria in Solid Tumors (RECIST 1.1) after administering at least four cycles of chemotherapy.</p><p><b>RESULTS</b>The median age was 52 years (range 16-73) in the whole group; 113 patients (36.2%) had locally advanced CRC, and 199 (63.8%) had metastatic CRC. Most patients (274/312, 87.8%) did not receive any treatment earlier. There were a total of 1651 chemotherapy cycles in the whole group, with a median of 6(1-19) cycles. Of these 1651 cycles, 124 cycles of chemotherapy(7.5%) were dose-adjusted; 176 cycles of chemotherapy(10.7%) were delayed for median 5(3-13) days; 124 cycles(7.5%) required dose decrease. The overall relative dose intensity was >90%; the specific drug dose intensity was 93.6%(2620 mg×m⁻²×d⁻¹) for fluorouracil, 97.8%(83 mg×m⁻²×d⁻¹) for oxaliplatin, and 94.2%(155 mg×m⁻²×d⁻¹) for irinotecan. Twenty-three patients (7 of intestinal perforation, 7 of intestinal obstruction, 1 of grade 4 hematologic toxicity, and 8 of grade 3 fatigue) refused subsequent chemotherapy due to intolerable toxicity. Main grade 3 or 4 adverse events in patients were neutropenia in 69 cases (22.1%), fatigue in 35 cases (11.2%), and anemia in 28 cases (8.9%). Twenty serious adverse events (6.4%) occurred, including 13 patients of febrile neutropenia (4.2%), 7 patients of intestinal perforation (2.2%, 4 patients in upper rectum, 2 in sigmoid colon, and 1 in transverse colon cancer), and 9 of them had subsequent sepsis (2.9%). All the patients with intestinal perforation underwent emergency operation. No treatment-related deaths occurred. In 199 patients with metastatic CRC, because 22 patients did not receive image evaluation, the preliminary efficacy of 177 patients was actually evaluated. A total of 113 objective response events were observed. The overall response rate was 63.8%(113/177), partial response rate was 61.6%(109/177), clinically complete response rate was 2.3%(4/177), stable disease was 29.9% (53/177), progressive disease was 6.2%(11/177), and the disease control rate was 93.8%(166/177). In 127 patients receiving triplet drug, objective response rate was 40.9% for those with less than four cycles and 81.1% for those with more than four cycles (P<0.001).</p><p><b>CONCLUSION</b>The mFOLFOXIRI regimen with reduced dose can be safely used in advanced CRC and has achieved promising results in terms of short-term efficacy.</p>

Objective@#To study the clinicopathologic characteristics, immunophenotype and ALK gene alterations of gastrointestinal inflammatory myofibroblastic tumor.@*Methods@#Clinical data, histological features and immunohistochemical results were analyzed in 7 cases of gastrointestinal inflammatory myofibroblastic tumor at Zhejiang Province Taizhou Hospital from January 2005 to December 2016. ALK gene status was investigated by ALK fluorescence in situ hybridization.@*Results@#There were 4 female and 3 male patients. The age of patients ranged from 1 to 72 years (median age=53 years and mean age=40 years). The tumor was located in stomach (n=4), left hemicolon (n=1), right hemicolon (n=1) and rectum (n=1). Histologically, the tumors consisted of spindle fibroblast and myofibroblast cells growing in bundles with inflammatory infiltration primarily composed of plasma cells and lymphocytes. Immunohistochemical study showed spindle tumor cells were positive for vimentin (7/7), SMA (7/7), but were negative for CD34, CKpan, CD117, DOG1, S-100 and desmin. Two cases expressed ALK protein and fluorescence in-situ hybridization revealed the presence of ALK gene rearrangement in the both cases.@*Conclusions@#Gastrointestinal inflammatory myofibroblastic tumor is a rare neoplasm that is easily misdiagnosed. Its surgical removal is a reliable treatment. ALK may be a potential novel therapeutic target for inflammatory myofibroblastic tumor.

ABSTRACT
Objective To evaluate the feasibility and safety of thoracoscopic lung cancer surgery under non-tracheal intubation anesthesia. Methods Twenty patients with peripheral lung cancer were enrolled in experimental group and control group. Then monitored and recorded Systolic pressure (SBP), diastolic pressure (DBP), mean arterial pressure (MAP), heart rate (HR), electrocardiogram (ECG), heart rate (HR), Oxygen saturation (SpO2), Final moisture CO2 partial pressure (PETCO2), central venous pressure, invasive arterial blood pressure and blood glucose and the related complications like sore throat, hoarse voice, nausea and so onin such time points: before induction (T0), induction of intubation (T1), operation (T2), and sudden removal (T3) of the two groups. Results The laryngeal mask group was given a smaller stimulus to the cardiovascular system during anesthesia.The time of feeding, the exhaust, the time of getting out of bed, the average hospitalization day, the reduction of hospitalization expenses, pharynx, respiratory and cardiovascular complications were shorter and less than intubation group. Conclusion The laryngeal mask ventilation intravenous anesthesia with thoracic vagal nerve block in the thoracoscopic lobectomy is simple, safe, no intubation-related complications and single lung ventilation lung injury, in line with surgery -anesthesia overall minimally invasive development concept, worthy of clinical promotion.
ABSTRACT
Objective To explore the value of tracheal intubation guided by fiberoptic bronchoscopy in children snoring disease operation.Methods A total of 50 patients underwent tracheal intubation guided by fiberoptic bronchoscope or laryngoscope from August 2015 to June 2016.There were 25 cases of fiberoptic bronchoscopy assigned into group A, 25 cases of laryngoscopy into group B.The intubation time, success rate and adverse reactions of the two groups were compared and analyzed.Results All the intubation in group A succeed at the first time.The intubation time was (20.1±4.3) s and the position was right.There was no need for replacement during the operation.Three cases in group B succeed at the second time because the tonsil was too big to expose the pharynx.The intubation got out of the pharynx in 3 cases in group B and were adjusted to the right position.The intubation time was (50.7±6.9) s and the success rate at the first time was 76% (19/25).Groups A behaved better than group B in aspects of the success rate of signal intubation and intubation time (Fisher''s Exact Test, P=0.022;t=-18.725, P=0.000).There were no adverse reactions in group A, such as pharyngorrhagia, odontoseisis or loss of tooth, laryngospasm and so on.There were 3 cases of hemorrhage from throat after intubation, 3 cases of loss of tooth in different degrees and 1 case of laryngospasm at second intubation time in group B.There was no significant difference in adverse reactions between the two groups (P>0.05).ConclusionFiberoptic bronchoscopy can be used for children snoring disease with good safety as well as rare adverse reactions.
ABSTRACT
Objective To assess the prognostic benefits of intraoperative radiotherapy (IORT) with electron beam among patients with unresectable locally advanced pancreatic cancer.Methods Between January 2009 and December 2014,167 patients with unresectable locally advanced pancreatic cancer received IORT with electron beam (10-20 Gy) in our hospital.After surgery,12 patients were treated with external beam radiotherapy,56 patients with chemoradiotherapy (CRT),and 17 patients with chemotherapy.Overall survival (OS),local recurrence,and toxicities were retrospectively analyzed.The Kaplan-Meier method was used to calculate survival rates,the log-rank test was used for survival difference analysis and univariate prognostic analysis,and the Cox model was used for multivariate prognostic analysis.Results The follow-up rate was 100％.The median OS time was 10.3 months,and the 2-year OS rate was 22％.The median progression-fiee survival (PFS) time was 6.3 months,and the 2-year PFS rate was 9.9％.The cancer-specific survival (CSS) time was 11.2 months,and the 2-year CSS rate was 23.6％.In the patients treated with IORT alone at doses of＜15 Gy,15 Gy and＞15 Gy,the median OS times were 6.2 months vs.9.1 months vs.22.2 months,and the 1-year OS rates were 10.0％ vs.39.6％ vs.74.4％ (P=0.000).Among the patients receiving postoperative adjuvant therapy,those treated with IORT+CRT had the best survival,with a median OS time of 11.6 months (P=0.033).The univariate analysis showed that IORT dose (P =0.000),tumor size (P =0.006),and IORT applicator diameter (P =0.007) were prognostic factors.The multivariate analysis showed that IORT dose (P=0.000) and IORT combined with CRT (P=0.006) were independent prognostic factors.Conclusions IORT with electron beam is an effective and safe treatment strategy for unresectable locally advanced pancreatic cancer.After protecting surrounding organs,increasing the IORT dose can improve the survival.IORT combined with CRT should be recommended because it improves survival for unresectable locally advanced pancreatic cancer without increasing toxicities.

ABSTRACT
Objective To investigate the diagnostic significance of thin layer reconstruction with spiral CT on the pulmonary hamartoma. Methods Accepted both routine CT examination and thin layer construction,2 1 pulmonary hamartoma cases confirmed by pathology were analyzed retrospectively.The margin and inner features of the lesions were observed and recorded.Significant analysis was performed by using SPSS17.0 Pearson chi-square test and Fisher exact test,with P<0.05 as the significant difference criterion.Results Comparison of the display rates by routine CT and thin layer reconstruction:①the same display rate of lobulation were 57.1%(12/21);②the same display rate of calcification were 42.9% (9/21);③the display rates of fat density were 14.3%(3/21)by routine CT and 42.9% (9/21)by thin layer reconstruction.The difference was statistically significant (χ2=4.200,P<0.05);④the display rates of blood vessel throughing were 14.3%(3/21)by routine CT and 47.6% (10/21)by thin layer reconstruction.The difference was statistically significant (χ2=5.459,P<0.05).Conclusion Displaying the inner features of pulmonary hamartoma better than routine CT,the thin layer reconstruction can improve the diagnostic accuracy significantly.
ABSTRACT
Objective:To develop an HPLC method for the determination of nintedanib in rabbit plasma and study the pharmacoki-netics of nintedanib in rabbits. Methods:The separation was performed on an Agilent ZORBAX SB-C18 column. A mixture of acetoni-trile-0. 1% trifluoroacetic acid-water (35∶ 20∶ 45) was used as the mobile phase at a flow rate of 1. 0 ml·min-1. The detection wavelength was set at 286 nm. Carbamazepine was used as the internal standard and nintedanib was extracted by ethyl acetate from plasma under basic condition. Totally 6 rabbits were given 20 mg·kg-1 nintedanib with intravenous administration. The blood samples were collected from the auricular vein at different time points after the administration. The concentration of nintedanib in plasma was detected by the HPLC method. The pharmacokinetics parameters were analyzed by DAS program. Results: An excellent linear rela-tionship was obtained within the range of 0. 05-10. 00 μg·ml-1(r=0. 999 8). The intra-day RSD was 5. 55%, 4. 53% and 2. 74%and inter-day RSD was 6. 15%, 5. 45% and 3. 15%, respectively for the three concentrations(0. 10, 2. 50 and 7. 50μg·ml-1), and the relative recovery was (98. 50 ± 5. 47)%, (100. 25 ± 4. 54)% and (99. 94 ± 2. 74)%, respectively. The main pharmacokinetics parameters of nintedanib were as follows: Cmaxwas (3.01 ±0.35) μg·ml-1, t1/2 was (4.38 ±1.53) h and AUC0-t was (11.67 ± 1. 71) μg·h·ml-1 . Conclusion:The method is simple, rapid and accurate, and can be used to determine the nintedanib concentra-tion in rabbit plasma and study its pharmacokinetics. Nintedanib is fitted the first-order elimination kinetics in rabbits.
ABSTRACT
Objective To investigate the effect of long-term antiviral treatment on clinical outcome and liver histology in patients with hepatitis B virus ( HBV)-related compensated cirrhosis .Methods A total of 61 patients with HBV-related compensated cirrhosis receiving antiviral therapy were enrolled from Taizhou Hospital of Zhejiang Province during September 2010 and March 2015, including 26 HBeAg-positive cases and 35 HBeAg-negative cases .Thirty-nine patients were treated with entecavir ( ETV ) and 22 were treated with adefovir dipivoxil ( ADV ) .Biochemical , serological and virological markers were examined every 3 months during treatment, and Child-Turcotte-Pugh (CTP) scores were calculated.All the patients underwent liver biopsy before and 144 weeks after antiviral treatment .Metavir scoring system was used to evaluate the liver histological activity ( A) and fibrosis score ( F) .Wilcoxon rank sum test and paired t-test were used for the evaluation of liver histopathology and liver function before and after treatment , respectively.Results After 144 weeks of antiviral treatment , HBV DNA was reduced and below the lower limit of detection in 58 patients (95.1%), HBeAg disappeared in 14 patients (14/26, 53.8%), and HBeAg seroconversion was observed in 10 patients (10/26, 38.5%); alanine aminotransferase ( ALT), aspartate amino transaminase (AST), total bilirubin (TBil) and CTP score decreased (t=7.489, 8.259, 14.000 and 6.026, all P<0.01), prothrombin time (PT) was shortened (t=9.777, P<0.01), and serum albumin (Alb) increased (t=3.446, P<0.01).Improvements in both liver histologic activity and fibrosis score were observed (Z=5.716 and 6.657, all P<0.01).Liver histological activity decreased from A1 to A0 in 16 cases, from A2 to A0 in 9 cases, from A2 to A1 in 15 cases, from A3 to A0 in 1 case, from A3 to A1 in 5 cases, and from A3 to A2 in 5 cases.Fibrosis score at the baseline was F 4 for all patients, while after treatment, there were 7 patients with F1, 22 with F2, 20 with F3, and F4 remained in rest 12 patients.Conclusion Both clinical and histological improvements can be obtained after long-term antiviral treatment for patients with HBV-related compensated cirrhosis .
