Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

Objective To investigate the effect of genetic factors on the occurrence of chronic post-thoracotomy pain syndrome ( PTPS) from the perspective of genetic polymorphisms. Methods Two hun-dred patients of both sexes, of American Society of Anesthesiologists physical statusⅠ or Ⅱ, aged 18-80 yr, scheduled for elective video-assisted thoracoscopic radical lung cancer surgery, were enrolled in this study. Blood samples were taken before operation for genotype analysis of 20 SNP loci, such as rs4073 and rs3774932, after DNA extraction. Postoperative multimodal analgesia was applied to maintain the visual an-alogue scale score ＜3. All the patients were followed up for 2-4 months after operation to record the occur-rence of PTPS. The patients were divided into 2 groups according to whether PTPS occurred: non-PTPS group (group N) and PTPS group (group P). Results The incidence of PTPS was 38. 7％ after surgery, and there were 114 patients in group N and 72 cases in group P . There was significant difference in A/T al-lele and genotype frequency at interleukin-8 rs4073 site and NF-κB1 rs3774932 site between the two groups (P＜0. 05). Conclusion Interleukin-8 and NF-kappa B1 genetic polymorphisms are associated with the occurrence of PTPS.

Objective To assess and compare the incidence,clinical characteristics,treatment,and prognosis of acute heart failure patients from different grades hospitals in Beijing.Methods In this prospective internet prognosis registered study (Beijing AHF Registry),a total of 3 335 consecutive patients admitted to 14 emergency departments in Beijing from January 1st 2011 to September 23rd 2012 were enrolled.According to hospital grade,these patients were divided into two groups,349 patients were from secondary hospitals,and 2 956 patients were from tertiary hospitals.Results Among the 3 335 patients,the medium age was 71 (58,79) years,and male accounted for 53.16％.The most common underlying disease were coronary disease (43.27％),hypertension (17.73％),cardiomyopathy (16.07％) etc.The average treatment time in Emergency Department was 66.82 h.The emergency department mortality rate was 3.81％ (127 cases).The 30-day and 1-year cumulative all-cause mortality were 15.3％ and 32.27％,respectively.The 30-day and 1-year cumulative all-cause readmission were 15.64％ and 46.89％,respectively.Compared with patients in tertiary hospitals,patients in secondary hospitals had more onset acute heart failure patients (63.64％ vs.49.93％),shorter emergency department treatment time (12 h vs.41 h),lower discharge rate (3.43％ vs.37.45％) and emergency department mortality(1.58％ vs.4.09％).Compared with those in tertiary hospitals,1-year cumulative all-cause mortality (25.6％ vs.33.2％),cardiovascular disease mortality (20.2％ vs.26.0％),aggravated heart failure mortality (22.4％ vs.28.8％) were lower in secondary hospitals.Following propensity score matching,compared to tertiary hospitals,patients in secondary hospitals showed lower utilization rate of beta-blockers and ACEFARB (4.51％ vs.28.17％,1.41％ vs.9.58％),except the pironolactone.Conclusion Acute heart failure in emergency department is associated with a high mortality rate and readmission rate.There is still a big gap between guidelines recommend medication current treatments for acute heart failure.

Objective To explore the value of conventional and functional MRI image parameter in preoperative grade of pancreatic neuroendocrine tumours (pNET).Methods Data of 35 cases of pNET were retrospectively analyzed,including tumor size,intensity of T1WI's and T2WI's signal,enhancement feature,and apparent diffusion coefficients (ADC)value.All kinds of tumors were classified into G1 to G3 according to WHO's classification in 2010.Results There were 40 pNETs (mean size(4.2±2.9)cm) among the 35 patients (20 male,and 15 female).By WHO's tumor grading,the number of patients from G1 to G3 was 18(45％),12(30％),and 10(25 ％),respectively.A higher grade was associated with larger tumor size (P＜0.05).Intensity of T1WI and T2WI signal has no significance for predicting tumor grade.Enhancement feature had statistical significance on tumor's grade (P＜0.05).ADC value decreased with the increase of tumor's grade,(2.23±0.80) × 10-3,(1.80±0.73) × 10-3,(0.92±0.24) ×10-3 mm2/s respectively for tumors from grade G1 to G3.Conclusion Enhancement features of MRI image and ADC value are conducive to preoperative grading of pNET.

OBJECTIVETo investigate the autopsy characteristics, pathologic type, malfomation and genetic characteristics of complete atrioventricular septal defect (CAVSD).

METHODSThirty five cases of CAVSD were collected from Maternal and Child Hospital of Haidian District during Jan.2003 to Jan.2015. Autoptic material, clinical history and chromosome examination were reviewed.

RESULTSAmong 35 cases of CAVSD between 18-38 gestational weeks, there were 26 cases with CAVSD A (74.3%, 26/35), 1 case with CAVSD B (2.8%, 1/35) and 8 cases with CAVSD C (22.8%, 8/35). Only CAVSD malformation was seen in 4 cases (11.4%, 4/35). Multiple malformations were seen in 31 cases (88.6%, 31/35). Combined malformations most frequently occurred in cardiovascular, respiratory and locomotor system. Among 15 cases with chromosome examination, chromosome aberrations was found in 13 cases (13/15) and trisomy-21 was found in 11 cases (11/15).

CONCLUSIONSCAVSD is a rare disease and CAVSD A is the most common type. CAVSD is usually combined with other malformations and chromosome aberrations.

Objective To investigate the diagnosis value of p16 combined with Ki67 protein in cervical lesions.Methods Totally 1 542 women with previous liquid-based cytology smear result of abnormality underwent a colposcopy-directed biopsy excision procedure.Biopsy specimens were detected by p16 and Ki67 immunostaining alongside hematoxylin and eosin (H&E) staining.A four-semiquantitative class was used to describe the immunohistochemical results.Results Biopsy results revealed 1 542 women included 473 women with negative for dysplasia (NEG),629 women with cervical intraepithelial neoplasia (CIN) Ⅰ,206 women with CIN Ⅱ,206 women with CINⅢ and 28 women with cervical squamous cell carcinoma (SCC).The averageage of this study population was 34.47 years.CINs mainly occurred in women aged 20-29 years and 30-39 years.The positive rates of p16 in NEG,CIN Ⅰ,CIN Ⅱ,CINⅢ and SCC were 15.22％,60.25％,98.06％,99.51％,100.00％ respectively,and the positive rates of Ki67 were 12.05％,63.12％,96.12％,98.06％,100.00％ respectively.p16 expression and Ki-67 expression significantly increased with disease progression (p16:r =0.758,P =0.000 ; Ki67:r =0.773,P =0.000).Expression level of p16 was positively related with Ki-67 (r =0.774,P =0.000).The positive expression rates of p16 and Ki-67 of NEG were significantly lower than those of CIN and SCC (p16:x2 =1 127.46,P =0.000;Ki67:x2 =1 316.85,P =0.000).The positive expression rates of p16 and Ki-67 were markedly higher in CIN Ⅰ than those in CINⅡ,CINⅢⅢ and SCC (p16:x2 =500.19,P =0.000;Ki67:x2 =603.23,P=0.000).Conclusion Women aged 20-39 years are key subjects for cervical cancer screening.p16 and Ki67 immunohistochemistry is important in the ancillary diagnosis of cervical lesions.

OBJECTIVETo study the etiology, pathogenesis, clinicopathologic characteristics, prognosis and treatment of congenital pulmonary airway malformation (CPAM).

METHODSEighteen cases of CPAM were enrolled into the study. The clinical history, autopsy findings and immunohistochemical results were evaluated, with review of literature. The pathogenetic mechanism, pathologic features and differential diagnosis of CPAM were studied.

RESULTSHistologic examination showed that 2 cases were classified as Stocker type I, 12 cases as type II, and 4 cases as type III. The lesion was unilateral and involved single lobe in 13 cases. The remaining 5 cases had bilateral diseases. Of the 18 cases studied, 12 cases showed single organ involvement and 6 cases had malformations affecting multiple organs. The associated malformations included cardiac anomalies (4 cases), polycystic kidney with gastrointestinal atresia (1 case) and nuchal cystic hygroma with hydrothorax (1 case).

CONCLUSIONSCPAM is a rare pulmonary disorder. The etiology of this non-neoplastic condition is unknown. Imaging analysis is a valuable tool to suggest CPAM, while definite diagnosis requires pathologic examination. The overall prognosis is determined by the presence of associated malformations, fetal hydrops and pulmonary hypoplasia.

OBJECTIVETo study the expression and clinicopathologic significance of cancer stem cell markers CD44v6 and CD24 in ovarian serous carcinoma tissues.

METHODSOne hundred and two cases of ovarian carcinoma diagnosed during the period from June, 2001 to December, 2010 were retrieved from archival files. The histology slides were reviewed and a two-tier system for grading of ovarian serous carcinoma was applied. The expression of CD44v6 and CD24 was detected by immunohistochemistry using EnVision method. The relationship between CD44v6/CD24 expression and various clinicopathologic parameters was analyzed.

RESULTSThere were 46.1% (47/102) and 59.8% (61/102) cases expressing CD44v6 and CD24, respectively. Both CD44v6 and CD24 expression showed positive correlation with higher histopathologic grade (P = 0.003 and P < 0.05, respectively). CD24 expression also correlated with the presence of lymph node metastasis (P < 0.05). There was no statistically significant relationship between the expression of these two markers (χ(2) = 0.394, P = 0.530). The age of the patients, histopathologic grade, clinical stage and nodal status correlated with progression-free survival time (P < 0.05). CD44v6 expression and histopathologic grade correlated with the overall survival time (P < 0.05). Patient age was an independent poor prognostic factor by multivariate analysis.

CONCLUSIONSCD44v6 expression, age older than 50 years, high clinical stage and presence of lymph node metastasis are associated with poor prognosis in patients with ovarian serous carcinoma. The two-tier system for grading of ovarian serous carcinoma is useful in predicting survival; and high tumor grade represents an important poor prognostic indicator for ovarian serous carcinoma.
