ABSTRACT

Objective:To investigate the value of three-dimensional reconstruction combined with serum carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA) detection in the diagnosis and resectability evaluation of hilar cholangiocarcinoma (HCCA) before resectable lymph node metastasis.Methods:A total of 65 patients with suspected HCCA who were treated at Yiwu Central Hospital from June 2019 to June 2022 were included in the observation group. Thirty healthy people who concurrently underwent physical examinations in the same hospital were included in the control group. All participants underwent a CT three-dimensional reconstruction examination. Simultaneously, the automatic electrochemiluminescence immunoassay analyzer was used to measure serum levels of CA19-9 and CEA. The outcomes of percutaneous transhepatic cholangiography were used as the "gold standard". The consistency between CT three-dimensional reconstruction, CA19-9 detection, and CEA detection, either individually or combined, and the "gold standard" in the diagnosis of HCCA was evaluated.Results:Serum levels of CA19-9 and CEA in the observation group were (62.71 ± 10.63) U/mL and (62.71 ± 10.63) ng/mL, respectively, which were significantly higher than those in the control group [(12.37 ± 7.39) U/mL, (1.31 ± 0.97) ng/mL, t = 23.43, 11.59, both P < 0.05). The levels of CA19-9 [(71.69 ± 12.37) U/mL] and CEA [(8.89 ± 3.51) ng/mL] in patients with HCCA who had lymph node metastasis were significantly higher than those in patients with HCCA who had no lymph node metastasis [CA19-9 (56.78 ± 10.16) U/mL, CEA (6.45 ± 2.11) ng/mL, t = 4.14, 2.76, both P < 0.05].Compared with histopathological examination, the accuracy of CT three-dimensional reconstruction in typing was 85.00%. According to the "gold standard" diagnosis, CT three-dimensional reconstruction, CA19-9 detection, and CEA detection, alone and their combination, successfully detected HCCA in 22 cases (55.00%), 26 cases (65.00%), 31 cases (77.50%), and 38 cases (95.00%), respectively. The detection rate of HCCA was the highest when CT three-dimensional reconstruction, CA19-9 detection, and CEA detection were combined, and the difference was statistically significant ( χ2 = 18.15, P < 0.05). Compared with CT three-dimensional reconstruction (AUC: 0.808), CA19-9 detection (AUC: 0.721), and CEA detection (AUC: 0.703) individually, their combination (AUC: 0.913) had the highest value in the diagnosis of HCCA (all P < 0.05). Conclusion:CT three-dimensional reconstruction, CA19-9 detection, and CEA detection have a certain diagnostic value for HCCA, but the combination of CT three-dimensional reconstruction with the detection of serum levels of CA19-9 and CEA has a higher diagnostic value for HCCA, providing an effective reference for the preoperative evaluation of the resectability of HCCA in the clinic.

ABSTRACT

Objective:To investigate the genetic risk factors and prognosis of 190 patients with myelodysplastic syndrome(MDS). Methods:The clinical data of 190 patients with MDS admitted to the Department of Hematology,The First Affiliated Hospital of Chongqing Medical University from January 2015 to October 2020 were analyzed retrospectively,and the genetic background and survival curve of the patients were also analyzed. Results:MDS patients with higher risk according to International Prognostic Score System(IPSS)stratification at the time of initial diagnosis had more frequent and complex types of gene mutation and chromosomal abnormalities,indicating poor prognosis.The choice of treatment is associated with the prognosis of MDS patients with intermediate risk(IPSS stratification),and the relative risk of the overall survival rate of patients treated with hypomethylating agents is higher than that of patients on concomitant medication. Conclusion:MDS patients with higher-risk(IPSS stratification)have more complex genetic risk factors and lower survival rate than those with lower-risk(IPSS stratification).MDS patients with multiple genetic risk factors have a poor prognosis,and the type of gene mutation is a predictor of prognosis.

ABSTRACT

Objective To investigate the relationship between the treatment of EGFR-TKI icotinib and the prognosis of advanced lung adenocarcinoma patients with EGFR mutation. Methods Patients with advanced lung adenocarcinoma who had EGFR19 and 21 gene mutations and were treated with EGFR-TKI icotinib were enrolled. The relationships of clinical features, EGFR gene mutation subtypes, and different sites with patients'prognosis were analyzed. Results A total of 101 patients with advanced lung adenocarcinoma were included in this study, including 58 cases (57.4%) of EGFR gene exon 19 deletion mutation (EGFR Del19) and 43 cases (42.6%) of EGFR gene exon 21 point mutation (EGFR L858R). The objective response rate was 63.4%. The mPFS and mOS were 13 months and 27 months, respectively. In addition, the mPFS and mOS of EGFR Del19 and EGFR19 mutation 746-750 were higher than those of EGFR L858R and other EGFR mutations, respectively. Meanwhile, multivariate analysis showed that the number of metastatic sites and pleural metastasis were independent influencing factors of patients'OS (P=0.027; P=0.041). The mOS of patients with the number of metastatic sites ≤3 and without pleural metastasis were 29 and 27 months, respectively. Conclusion There is no significant difference found in overall survival of advanced lung adenocarcinoma patients treated with icotinib among different EGFR mutation subtypes and sites. Herein, the overall survival time is longer in patients with less than three metastatic sites and without pleural metastasis.

ABSTRACT

Objective:To explore the clinical characteristics and influencing factors of hematologic disease patients with chronic graft-versus-host disease (cGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and their effects on the prognosis of patients.Methods:The clinical data of 225 hematologic disease patients who underwent allo-HSCT from January 2014 to February 2021 in the First Affiliated Hospital of Chongqing Medical University were retrospectively analyzed. The efficacy of allo-HSCT, post-transplantation infection, as well as the incidence of cGVHD and its related factors, and its effect on the overall survival (OS) rate, disease-free survival (DFS) rate, cumulative incidence of relapse (CIR) and non-relapse mortality (NRM) rate of patients according to Seattle diagnostic criteria and National Institutes of Health (NIH) diagnostic criteria were analyzed.Results:All 225 hematologic disease patients had hematopoietic reconstruction after allo-HSCT. Among the 225 patients, 156 patients (69.33%) had early infection (207 times), and 92 patients (40.89%) had late infection (107 times). According to the Seattle diagnostic criteria, 58 patients developed cGVHD (111 times), with a cumulative incidence of 39.5%. The involved organs included skin (33 times), liver (32 times), eyes (19 times), lung (11 times), oral cavity (10 times), intestine (4 times) and hematological system (twice). Multivariate Cox regression analysis showed that acute graft-versus-host disease (aGVHD) was an independent influencing factor for cGVHD ( HR= 3.706, 95% CI 2.025-6.783, P<0.001). Compared to patients without cGVHD, patients with cGVHD had lower 5-year CIR (4.0% vs. 21.8%, P= 0.010) and higher 5-year NRM rate (25.5% vs. 11.8%, P= 0.029), while 5-year OS rate (72.5% vs. 73.6%, P= 0.908) and DFS rate (64.6% vs. 65.9%, P= 0.670) between the two groups had no statistical difference. Compared to patients with limited cGVHD, patients with extensive cGVHD had lower 5-year OS rate (56.0% vs. 83.9%, P= 0.035), lower 5-year DFS rate (52.0% vs. 73.4%, P = 0.038) and higher 5-year NRM rate (43.0% vs. 13.0%, P = 0.018). More erythrocyte suspension infusion during the transplantation was an independent influencing factor for early infection ( P = 0.011). Blood type incompatibility between donor and recipient ( P = 0.017), limited cGVHD ( P = 0.039) and extensive cGVHD ( P = 0.003) were independent influencing factors for late infection. According to the NIH diagnostic criteria, 5 patients (8.62%) who developed cGVHD after 100 days of transplantation were reclassified as aGVHD, and 12 patients (20.69%) were reclassified as overlap syndrome. The cumulative incidence of cGVHD was 36.4%, and aGVHD was the only independent influencing factor for cGVHD ( P<0.001). Compared to patients without cGVHD, patients with cGVHD had lower 5-year CIR (6.7% vs.21.7%, P = 0.006) and higher 5-year NRM rate (26.1% vs. 12.0%, P = 0.035), while 5-year OS rate (73.7% vs. 73.2%, P = 0.845) and DFS rate (64.9% vs. 65.7%, P = 0.522) between the two groups had no statistical difference. Conclusions:The incidence of cGVHD after allo-HSCT in hematologic disease patients is high, and there are many organs involved. cGVHD can reduce the relapse rate of patients, but severe cGVHD increases the mortality of patients. aGVHD is the only independent influencing factor for cGVHD.

ABSTRACT

α-Amino acid ester acyltransferase (Aet) catalyzes the L-alanyl-L-glutamine forming reaction from L-alaine methylester hydrochloride and L-glutamine. In this study, the recombinant Escherichia coli saet-QC01 was used to express the α-amino acid acyltransferase, and its expression conditions were optimized. The recombinant protein was separated and purified by Ni-NTA affinity chromatography, and its enzymatic properties and catalytic applications were studied. The induction conditions suitable for enzyme production optimized were as follows: The temperature was 20 ℃, the induction stage (OD₆₀₀=2.0-2.5), IPTG concentration was 0.6 mmol/L, induction time was 12 h. The optimal reaction conditions of α-amino acid acyltransferase were 27 ℃, pH 8.5, it was most stable between pH 7.0 and 8.0 and relatively stable in an acidic environment, and low concentration of Co²⁺ or EDTA could promote the enzyme activity. Under optimal reaction conditions, 600 mmol/L of L-alaine methylester hydrochloride and 480 mmol/L of L-glutamine, the yield of L-alanyl-L-glutamine reached 78.2 g/L and productivity of 1.955 g/L/min, the conversion rate reached 75.0%. α-Amino acid ester acyltransferase has excellent acid-basei resistance, high catalytic efficiency. These characteristics suggest its application prospects in the industrial production.

ABSTRACT

OBJECTIVE:To observe clinical efficacy and safety of Tobramycin dexamethasone ointment in Nd∶YAG laser lac-rimal duct plasty. METHODS:Medical records of 1000 patients(1250 eyes)with obstructive lacrimal duct disease receiving To-bramycin dexamethasone ointment in Nd∶YAG laser lacrimal duct plasty were selected from our hospital during Jan. 2013-Jan. 2017. They were divided into chronic dacryocystitis group(380 eyes),small tears(total)tube obstruction group(360 eyes),naso-lacrimal duct obstruction group (342 eyes),punctal occlusion group (86 eyes) and traumatic canalicular laceration group (82 eyes)according to the lacrimal duct obstruction. In 5 groups,heated Tobramycin and dexamethasone ophthalmic ointment would be loaded in 1 mL syringe and injected into the lacrimal duct via probe,dropping the probe while pushing the ointment. They received lacrimal duct flushing regularly and were followed up for 3 months. Therapeutic efficacies and safty were compared among 5 groups. RESULTS:Cure rate and response rate of patients with chronic dacryocystitis were 85.00% and 87.63%;those of patients with lacrimal small (total) obstruction were 87.78% and 94.45%;those of patients with nasolacrimal duct obstruction were 89.18% and 95.03%;those of patients with punctal occlusion were 84.88% and 94.18%. All of above were significantly higher than 42.68%and 64.63%of patients with traumatic canalicular laceration,with statistical significance(P<0.05). There was no sta-tistical significance in the incidence of ADR among 5 groups(P>0.05). CONCLUSIONS:In the treatment of chronic dacryocysti-tis,small tears(total)tube obstruction,nasolacrimal duct obstruction and punctal occlusion,application of Tobramycin dexametha-sone eye ointment in Nd∶YAG laser lacrimal duct plasty shows good therapeutic efficacy and has less ADR.

ABSTRACT

Objective To study the role of capsaicin on improving the sensitivity of cholangiocarcinoma (CCA) cells to 5 fluorouracil(5-FU)and to investigate its molecular mechanism.Methods The MTT and animal experiment were performed to study the effect of capsaicin on the sensitivity of CCA cells to 5-FU,and the q-PCR and Western blot were performed to study its molecular mechanism.Results The effect of 5-FU inhibiting the growth of CCA cells and in vivo was significantly enhanced by capsaicin (60 μmol/L),as well as the apoptosis induced by 5-FU (P < 0.01).In molecular mechanism study,capsaicin down-regulated the expression of beclinl and atg5,but inhibited the 5-FU-induced autophagy of CCA cells.In addition,capsaicin effectively increased the phosphorylation levels of S6 (S235/236) and AKT (S473).Conclusions Capsaicin can promote cell apopto sis and inhibit cell autophagy to improve the sensitivity of CCA cells to 5-FU significantly,which maybe associated with the activation of PI3K/AKT/mTOR pathway in CCA cells.

ABSTRACT

Objective To retrospectively analyze the influence factors during autologous peripheral blood stem cell (PBSC) mobilization and collection process in the patients with non-Hodgkin′s lymphoma (NHL).Methods Forty-eight patients with NHL in our hospital from January 2014 to August 2016 underwent PBPC mobilization and collection.The factors of age,sex,disease stage,bone marrow involvement at diagnosis,chemotherapy frequency,relapse and so on were analyzed retrospectively.Results PBSC mobilization and collection was successful in 37 cases (77.10%).The success rate was affected by the time from diagnosis to mobilization (P=0.038),chemotherapy courses (P=0.016),prior chemotherapy including fludarabine (P=0.049),relapse(P=0.033),and the levels of white blood cell (P=0.014) and platelet (P<0.01) before stem cells collection.Conclusion For the patients planning to receive autologous peripheral blood stem cell transplantation,many times of prior chemotherapy are unfavorable,mobilization and collection should be taken as early as possible,chemotherapeutic agents which possibly injure stem cells should be avoided,it is needed to simultaneously pay attention to peripheral blood WBC and platelet level for determining the collection timing.

ABSTRACT

Objective To evaluate the diagnostic value of MSCT in the differentiation of thymic epithelial tumours (TET)with the maximum diameter equal or less than 3 cm.Methods A retrospective analysis of pathological and imaging data of 56 patients with pathologically confirmed TET with the maximum diameter equal or less than 3 cm was performed.According to the 2004 WHO classification,56 TETs were classified as low-risk thymomas(types A/AB/B1),high-risk thymomas (types B2/B3)and thymic carcinomas (type C).The CT manifestations of TET in each group,including shape of tumor,tumor edge (smooth or spiculate protuberance), presence of small nodule around tumor,enhancement degree,pleura invasion and fat space around tumor,were analyzed retrospectively.The differences in the CT manifestations among three types were compared using chi-square test.If the sample number was too small, Fisher 's exact test was used.Results Compared with high-risk thymomas (23 cases)and thymic carcinomas (6 cases),regular round shape was more often observed in low-risk thymomas (27 cases)(χ2 =73,P <0.001;χ2 =116,P <0.001)and the mediastinum-lung interface was more likely to bulge (χ2 = 3.41,P =0.046;χ2 =7.39,P =0.01).Blurred edge,spiculate protuberance and pleural invasion and so on were significantly more common in high-risk thymomas and thymic carcinomas (P <0.001)and they were the most common in thymic carcinomas (χ2 =11.5,P =0.009).There was a significant difference between type B2 thymomas and thymic carcinomas (χ2 =31.52, P <0.001),however there was no significant difference between type B3 thymomas and thymic carcinomas (χ2 =6.96,P =0.07). Conclusion MSCT can accurately show the shape of tumor,tumor edge,presence of small nodule around tumor,enhancement degree,pleura invasion,which can predict the histologic type of thymomas and also can provide information for preoperative diagnosis and prognosis evaluation.

ABSTRACT

BACKGROUND:Al ogeneic hematopoietic stem cel transplantation (HSCT) is one of the effective methods in the treatment of leukemia. The haploidentical HSCT is an option for the patients who need a HSCT without a human leukocyte antigen (HLA)-matched donor. OBJECTIVE:To study the clinical efficacy of HLA-haploidentical HSCT on leukemia and its complications. METHODS:A total of 23 patients (4 cases of acute lymphoblastic leukemia, 12 of acute myelogenous leukemia, and 7 of chronic granulocytic leukemia) who had been treated with HLA-haploidentical HSCT from November 2007 to March 2015 were enrol ed. Conditioning regimen I was set as cyclohexyl nitrosourea+cytarabine+busulfan+cyclophosphamide; regimen II as cyclophosphamide+total body irradiation;regimen III as fludarabine+cytarabine+busulfan+cyclophosphamide; and regimen IV as busulfan+cyclophosphamide. Cyclosporin A, mycophenlate mofetil, antithymocyte globulin and methotrexate were used to prevent graft-versus-host disease (GVHD). Hematopoietic remodeling, complications and prognosis were observed in al patients undergoing HLA-haploidentical HSCT. RESULTS AND CONCLUSION:Of the 23 patients, 22 achieved reconstitution of the granulocyte series, and 19 achieved reconstruction of the megakaryocyte series. Additional y, there were 7 cases of acute GVHD and 4 of chronic GVHD. Transplant-related mortality was 22%(5/23) within 100 days post transplantation including graft failure, acute GVHD, intracranial hemorrhage and disseminated infections. There were 14 cases of disease-free survival from 100 days to 24 months post transplantation, 2 cases of death due to GVHD and fungal infection, or recurrence and chronic GVHD, and 2 cases of recurrence under treatment. These findings indicate that HLA-haploidentical HSCT is an effective approach for the treatment of patients with leukemia, which is worth further investigation in clinical practice.
