ABSTRACT

A fast,reliable,and cost-effective liquid chromatography-tandem mass spectrometry method was established to determine the effects of the traditional Chinese medicine employed to treat coronavirus disease 2019,namely,Lianhua Qingwen granules,Huoxiang Zhengqi capsules,Jinhua Qinggan granules,Shufeng Jiedu capsules,and Angong Niuhuang pills,on the pharmacokinetics of lopinavir/ritonavir in rats.Blood samples were prepared using the protein precipitation method and atazanavir was selected as the internal standard(IS).Separation was performed on an Agilent ZORBAX eclipse plus C18(2.1 mm x 50 mm,1.8 μm)column using acetonitrile and water containing 0.1%formic acid as the mobile phase for gradient elution.The flow rate was 0.4 mL/min and the injection volume was 2 μL Agilent Jet Stream electrospray ionization was used for mass spectrometry detection under positive ion multiple reaction monitoring mode at a transition of m/z 629.3→447.3 for lopinavir,m/z 721.3→296.1 for rito-navir,and m/z 705.4→168.1 for the IS.The method showed good linearity in the concentration range of 25-2500 ng/mL(r=0.9981)for lopinavir and 5-500 ng/mL(r=0.9984)for ritonavir.The intra-day and inter-day precision and accuracy were both within±15%.Items,such as dilution reliability and residual effect,were also within the acceptable limits.The method was used to determine the effects of five types of traditional Chinese medicines on the pharmacokinetics of lopinavir/ritonavir in rats.The pharmaco-kinetic results showed that the half-life of ritonavir in the groups administered Lianhua Qingwen granules and Huoxiang Zhengqi capsules combined with lopinavir/ritonavir was prolonged by approx-imately 1.5-to 2-fold relative to that in the control group.Similarly,the pharmacokinetic parameters of lopinavir were altered.Overall,the results of this study offer important theoretical parameters for the effective clinical use of five types of traditional Chinese medicines combined with lopinavir/ritonavir to reduce the occurrence of clinical adverse reactions.

ABSTRACT

Purpose@#Intrahepatic cholangiocarcinoma (ICC) is one of the most common liver primary tumors but its treatments are limited. Bioinformatics showed that the expression level of long non-coding RNA cancer-associated susceptibility 15 gene (CASC15) is correlated with ICC progression, but its functional mechanism remains unclear. @*Materials and Methods@#Tissues from ICC patients, tumor and adjacent tissue, were used for detection of the expression of CASC15. Clinical data were also collected for clinicopathologic and survival analysis. Short interfering RNA and lentiviral short hairpin RNA were used to knock down CASC15 and PRDX2 expression in ICC cell lines, for the analysis of changes of cell function and xenografts. RNA-pulldown and RNA immunoprecipitation assays were used to detect RNA-binding protein, PRDX2. Male nude mice were used for ICC xenografts, and livers were collected after 4 weeks for immunohistochemistry. @*Results@#CASC15 is highly expressed in ICC tissues and is related to higher TNM stage. Knockdown of CASC15 in ICC cells reduced cell proliferation, migration, invasiveness and increased apoptosis, and G1/S block. PRDX2 bound to CASC15. Knockdown of CASC15 decreased PRDX2 expression which was rescued by the inhibition of proteasome formation. Downregulation of PRDX2 resulted in G1/S block, reduced ICC cell invasion. Downregulation of CASC15 inhibited phosphoinositide 3-kinase (PI3K)/AKT/c-Myc pathway through downregulating of PRDX2 and overexpressed PRDX2 rescued the block. CASC15 knockout in ICC xenografts suppressed tumor development in vivo, decreased the expression of PRDX2 and Ki67 and inhibited PI3K/AKT pathway. @*Conclusion@#CASC15 promotes ICC possibly by targeting PRDX2 via the PI3K/AKT pathway, indicating poor prognosis and high degree of malignancy of ICC.

ABSTRACT

Purpose@#Previous studies have demonstrated the usefulness of the controlling nutritional status (CONUT) score in nutritional assessment and survival prediction of patients with various malignancies. However, its value in advanced gastric cancer (GC) treated with neoadjuvant chemotherapy and curative gastrectomy remains unclear. @*Materials and Methods@#The CONUT score at different time points (pretreatment, preoperative, and postoperative) of 272 patients with advanced GC were retrospectively calculated from August 2004 to October 2015. The χ2 test or Mann-Whitney U test was used to estimate the relationships between the CONUT score and clinical characteristics as well as short-term outcomes, while the Cox proportional hazard model was used to estimate long-term outcomes. Survival curves were estimated by using the Kaplan-Meier method and log-rank test. @*Results@#The proportion of moderate or severe malnutrition among all patients was not significantly changed from pretreatment (13.5%) to pre-operation (11.7%) but increased dramatically postoperatively (47.5%). The pretreatment CONUT-high score (≥4) was significantly associated with older age (P=0.010), deeper tumor invasion (P=0.025), and lower pathological complete response rate (CONUT-high vs. CONUT-low: 1.2% vs. 6.6%, P=0.107). Pretreatment CONUT-high score patients had worse progression-free survival (P=0.032) and overall survival (OS) (P=0.026). Adjusted for pathologic node status, the pretreatment CONUT-high score was strongly associated with worse OS in pathologic nodepositive patients (P=0.039). @*Conclusions@#The pretreatment CONUT score might be a straightforward index for immunenutritional status assessment, while being a reliable prognostic indicator in patients with advanced GC receiving neoadjuvant chemotherapy and curative gastrectomy. Moreover, lower pretreatment CONUT scores might indicate better chemotherapy responses.

ABSTRACT

Objective To summarize the technical experience of extracorporeal membrane oxygena-tion(ECMO)catheterization in children. Methods Data of patients that received ECMO treatment in the pe-diatric intensive care unit between October 2016 and October 2018 were analyzed retrospectively. The age, weight,diagnosis,complications and the final outcomes of the patients,as well as the working mode,catheter-ization mode and duration of ECMO were collected. Results A total of 15 children were treated with ECMO,including 5 males and 10 females. The median age(range) was 4. 9 (1. 0-11. 0)years and the median weight(range) was 21. 5(8. 5-49. 0)kg. There were 5 cases of fulminant myocarditis,7 cases of severe pneu-monia,3 cases of septic shock,8 cases of venous-arterial bypass( VA mode),and 7 cases of venous-venous bypass(VV mode). All the 15 patients underwent percutaneous catheterization. Two patients that experienced difficulty in percutaneous catheterization turned to open catheterization. None abandoned ECMO due to the difficulty in catheterization. The position and depth of the catheter,and the flow rate required no further ad-justment. The mean ECMO duration was 96. 8(1-366)h. Weaning was successful in 8 cases(53%). One case was transferred and 8 cases were dismissed,and the survival rate was 60%. There were 2 cases of bleeding at the site of catheter entrance,one treated with local compression and the other with suture. There was 1 case of femoral artery thrombosis that was relieved by percutaneous femoral artery angiography and intracavitary for-mation. Another case developed carotid artery thrombosis and had been undergoing antithrombotic therapy and following-up. One case had nerve injury in the left lower extremity that was relieved by oral vitamin Bs and low frequency electrical stimulation. Conclusion Catheterization is the basis of ECMO execution. Catheter-ization method should be individualized. Percutaneous catheterization is the choice of thumb due to its safety and simplicity. In case of failure,or during the extra-cardiac compression,the surgical method should be taken quickly,and the catheter should be placed in an open or partly-open manner. Proficient catheterization tech-nique ensures the smooth application of ECMO in children.

ABSTRACT

Objective To investigate the fetal management of prenatally diagnosed fetal mediastinal masses and the initial experience of neonatal thoracoscopic minimally invasive treatment. Methods We per-formed a retrospective study from November 2015 to November 2016 of all newborns affected by mediastinal masses and treated by thoracoscopic surgery. This group of cases were found with mediastinal masses by pre-natal ultrasound. The earliest detection of abnormal time was 16 to 31 weeks of pregnancy,with an average of 25 weeks. In the fetal period,the patients were treated with multidisciplinary consultation and individual man-agement. Prenatal examinations helped us except for chromosomal abnormalities and other organ abnormali-ties. After birth,the patients underwent CT and MRI examination. The diameter of the tumor was 1. 7 to 5. 7 cm,with an average of 3. 2 cm. The operative age was 4 to 29 days,with an average of 12. 4 days. This group of newborns were performed thoracoscopic mass resection and confirmed by intraoperative pathological exam-ination. Results After individualized precise prenatal management,all children were born successfully and confirmed that prenatal diagnosis was accurate. All mediastinal masses were completely excised in the neo-natal period. Five mediastinal masses were completely excised. One posterior mediastinum immature teratoma was converted to open thoracotomy. The mean operative duration was 112 min(100 to 150 min). There was no operative complication with a minimal amount of blood loss. With a smooth recovery,the hospital stay was 11-17 days. Pathological results included:1 esophageal duplication,2 bronchogenic cysts,1 lymphangioma, 1 cystic teratoma of anterior mediastinum,1 immature teratoma of posterior mediastinum. During a mean fol-low-up period of 8-14 months,neither complication nor recurrence occurred. Conclusion These are the pre-conditions for early treatment of neonatal patients with mediastinal masses,including definite prenatal diagno-sis,multidisciplinary consultation system and individualized and accurate fetal management. Throcoscopic ex-cision of mediastinal masses is both feasible and safe in neonates. Proper preoperative case selection may pre-vent a conversion into thoracotomy due to huge solid mass.

ABSTRACT

Objective To detect the sequence of SLC29A1 gene rs1288 single nucleotide polymorphism (SNP) in advanced pancreatic cancer patients,and to explore its correlation with gemcitabine toxicity and prognosis.Methods Peripheral blood samples were collected and DNA was extracted.The segment containing SLC29A1 gene SNP (rs1288) was amplified by PCR,and then DNA sequencing was conducted to identify SLC29A1 gene SNP (rs1288).According to the sequencing results,the patients were divided into SLC29A1 gene rs1288 T→A mutation type group and wild type group.Clinical data,toxicity of gemcitabine chemotherapy,progression free survival (PFS) and overall survival (OS) between two groups were compared.Results A total of 83 pancreatic cancer patients were enrolled.Sequencing results showed that SLC29 A1 gene 1288 T→A mutation type was present in 52 patients and wide type was observed in 31 patients,so mutation rate was 62.7%.All the patients in both two groups could tolerate the gemcitabine toxicity,and no chemotherapy related death occurred.There were no statistical differences on the gender,age,CA19-9,tumor site,size and TNM stage between the two groups.There were statistically higher iucidences of leukopenia and thrombocytopenia in the SLC29A1 gene rs1288 T →A mutation type group compared to the wild type group (55.8% vs 32.3%,P<0.05;40.4% vs 19.4%,both P<0.05).Median OS and PFS in mutation type group were shorter than those in wide type group (11 months vs 14 months,P < 0.05;9 months vs 12 months,P < 0.05).Conclusions Advanced pancreatic cancer patients with the SLC29A1 gene rs1288 T→A mutation type had a higher incidence of adverse reaction in gemcitabine chemotherapy and a worse therapeutic effect,and thus detecting the mutation of SLC29A1 gene rs1288 point mutation may serve as a marker for evaluating the toxicity and prognosis of gemcitabine chemotherapy in patients with pancreatic cancer.

ABSTRACT

Objective: To evaluate the feasibility and safety of applying enhanced recovery after surgery (ERAS) protocol in patients undergoing laparoscopic distal pancreatectomy. Methods: Data of 36 patients undergoing laparoscopic distal pancreatectomy from May 2016 to May 2017 in the First Affiliated Hospital, Zhejiang University School of Medicine were reviewed. The patients were divided into ERAS group (n=12) and control group (n=24). The patients in ERAS group received a series of enhanced recovery procedures, including multimodal analgesia, early off-bed activity and early oral food-taking, etc. Operation time, intraoperative blood loss, time to first flatus, postoperative complications, and length of postoperative hospital stay were evaluated. Results: There were no statistically significant differences in operation time and intraoperative blood loss between ERAS group and control group (all P0.05). The time to first flatus and length of postoperative hospital stay were significantly shortened in ERAS group (all PP0.05). Conclusion: The ERAS protocol for laparoscopic distal pancreatectomy can significantly promote gastrointestinal function recovery and shorten postoperative hospital stay, and may reduce the incidence of postoperative complications.

ABSTRACT

BACKGROUND/AIMS: We aimed to evaluate the efficacy and safety of an immunosuppressive regimen without steroids after liver transplantation (LT) for hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). METHODS: Sixty-six HCC patients who underwent an immunosuppressive regimen without steroids after LT were enrolled in the steroid-free group. The preoperative characteristics and postoperative outcomes of these patients were compared with those of 132 HCC recipients who were placed on an immunosuppressive regimen using steroids (steroid group). The incidence of acute rejection, HBV recurrence, infection, and new-onset diabetes mellitus and the overall and tumor-free survival rates were compared between the two groups. RESULTS: Differences were not observed in the 1-year (83.3% vs 97.0%, p=0.067), 3-year (65.4% vs 75.8%, p=0.067) or 5-year (56.3% vs 70.7%, p=0.067) patient survival rates or in the 1-year (62.1% vs 72.7%, p=0.067), 3-year (49.8% vs 63.6%, p=0.067) or 5-year (48.6% vs 63.6%, p=0.067) tumor-free survival rates between the two groups, respectively. In the steroid-free group, the patients who fulfilled the Milan criteria had higher overall and tumor-free survival rates than those in the steroid group (p<0.001). The prevalence of HBV recurrence (3.0% vs 13.6%, p=0.02) was significantly lower in the steroid-free group compared with the steroid group. CONCLUSIONS: After LT, an immunosuppressive regimen without steroids could be a safe and feasible treatment for HBV-related HCC patients, thus resulting in the reduction of HBV recurrence. Based on the observed survival rates, patients who fulfill the Milan criteria may derive benefits from steroid-free immunosuppression.

ABSTRACT

Objective To explore the application of transcatheter arterial chemoembolization (TACE) combined with selective portal vein embolization (SPVE ) in two-stage hepatectomy of hepatocellular carcinoma (HCC).Methods From September 2010 to September 2013,a total of 107 patients with HCC in the right liver lobe who were not suitable for one stage hepatectomy received TACE or TACE combined with SPVE treatment were enrolled.Among them,55 received TACE therapy and 52 accepted TACE combined with SPVE treatment.The technique success rate,complication,adverse reactions,the volume change of each liver lobe and the rate of hepatectomy of HCC were observed.Chi-square test was used for numerical data comparison and Student′s t test for measurement data.Results TACE or TACE combined with SPVE therapy was successfully applied in all the 107 patients,the technique success rate was 100%.During treatment period,no complications such as ectopic embolization, liver function failure,puncture tract bleeding,gastrointestinal bleeding,bile leakage and hepatic abscess were observed.After treatment,the adverse reactions included liver function impairment,pain in hepatic region,fever,nausea and vomiting.Four weeks after the treatment,the volumes of tumor and right liver lobe decreased to certain degree in patients with HCC of both TACE group and TACE combined with SPVE group.The volume of left liver lobe in TACE group had no obvious change,while remarkably increased in TACE combined with SPVE group.The pre-treatment residual liver volume (RLV)of TACE group and TACE combined with SPVE group was (404.0 ± 46.3 )cm3 and (393.9 ± 65 .7 )cm3 , respectively,and the difference was not statistically significant (t=0.927,P =0.356).Four weeks after the treatment,RLV was (415.4 ±45.7 )cm3 and (567.3 ±88.7 )cm3 ,respectively,and the difference was statistically significant (t= -11 .219,P <0.05).Patients were followed up for three to six months,the rates of hepatectomy were 38.2%(21/55)and 86.5 %(45/52)in TACE group and TACE combined with SPVE group,and the difference was statistically significant (χ2 =26.440,P <0.01 ).Conclusion For patients with HCC not suitable for one stage hepatectomy,the treatment of TACE combined with SPVE before operation could effectively control the growth of the tumor,decrease the volume of tumor,increase RLV,and then increase the rate of two-stage hepatectomy.

ABSTRACT

Stereotactic body radiotherapy (SBRT) can treat the lesions in asurgical manner and inhibit tumor cell proliferation.Furthermore,it has a character of non-invasive,which shortens the duration of treatment.Although surgery and radiotherapy are the major means for early stage peripheral non-small cell lung cancer,some studies in recent years show that SBRT has certain advantages in local control ratio and adverse reaction compared with radiotherapy,and acquires the similar curative effect with surgery.

ABSTRACT

Objective:To compare the effect of the frequency of transcatheter arterial chemoembolization (TACE) on preventing tumor recurrence after hepatectomy. Methods:A total of 45 post-operative patients who had received prophylactic TACE once or thrice were retrospectively examined between January 2008 and June 2009. Of the 45 patients, 23 underwent TACE once, and the others un-derwent it thrice. TACE was administered to all patients via the hepatic artery one to two months after operation and was repeated every two to four months with patients who underwent TACE three times. All cases were followed up for 36 to 40 months after surgery. The rates of cumulative recurrence between the two groups were compared. Results:In the group that underwent TACE once, the 1-, 2-and 3-year cumulative recurrence rates were 30.43%, 47.83%, and 47.83%, respectively. In the group that underwent TACE thrice, the 1-, 2-and 3-year cumulative recurrence rates were 4.55%, 27.27%, and 36.36%, respectively. Statistical analysis showed that the relapse rate within one year was lower in the group that underwent TACE thrice than in the group that underwent TACE only once (P=0.022). How-ever, no significant difference in the cumulative recurrence rate was found between the two groups in two and three years (P=0.086, 0.225). Conclusion:Hepatocellular carcinoma patients who undergo preventive TACE three times after hepatectomy exhibit reduced re-currence rates during the peak time of tumor recurrence and extended disease-free survival intervals.
