OBJECTIVE: To investigate the clinical characteristics and prognosis of primary pulmonary lymphoma (PPL). METHODS: The clinical data of 17 patients with PPL admitted to Gansu Provincial Hospital from January 2013 to June 2023 were collected, and their clinical characteristics and prognosis were retrospectively analyzed and summarized. RESULTS: The median age of the 17 patients was 56 (29-73) years old. There were 8 males and 9 females. According to Ann Arbor staging system, there were 9 patients with stage I-II and 8 patients with stage III-IV. There were 14 patients with IPI score of 0-2 and 3 patients with IPI score of 3-4. All 17 patients had symptoms at the initial diagnosis, most of the first symptoms were cough, and 6 patients had B symptoms.Among the 17 patients, there were 8 cases of diffuse large B-cell lymphoma (DLBCL), 5 cases of mucosa-associated lymphoid tissue (MALT) lymphoma, 1 case of gray zone lymphoma (GZL), and 3 cases of Hodgkin's lymphoma (HL). 15 patients received chemotherapy, of which 3 cases received autologous hematopoietic stem cell transplantation(ASCT) and 3 cases received radiotherapy; 2 patients did not receive treatment. The median number of chemotherapy courses was 6(2-8). The short-term efficacy was evaluated, 12 patients achieved complete remission (CR) and 3 patients achieved partial remission (PR). The age, pathological subtype, sex, Ann Arbor stage, β₂-microglobulin(β₂-MG) level, lactate dehydrogenase(LDH) level were not correlated with CR rate (P >0.05), while IPI score was correlated with recent CR rate (P < 0.05 ). The median follow-up time was 31(2-102) months. One of the 12 CR patients died of COVID-19, and the rest survived. Among the 3 patients who did not reach CR, 1 died after disease progression, while the other 2 survived. One of the 2 untreated patients died one year after diagnosis. Both the median progression-free survival (PFS) time and overall survival (OS) time of the 17 patients were both 31 (2-102) months. CONCLUSION The incidence of PPL is low, and the disease has no specific clinical manifestations, which is easily missed and misdiagnosed. The pathological subtypes are mainly MALT lymphoma and DLBCL, and the treatment is mainly combined chemotherapy. The IPI score is related to the treatment efficacy.

Objective:To analyze the prognostic nutritional index(PNI),controlling nutritional status(CONUT)and fibrinogen/albumin ratio(FAR)levels in elderly patients with multiple myeloma(MM)and their prognostic impact.Methods:The clinical data of 74 elderly MM patients diagnosed in Gansu Provincial Hospital from January 2020 to July 2022 were retrospectively analyzed.The optimal cut-off values for PNI,CONUT score and FAR were obtained by receiver operating characteristic(ROC)curve,which were used for grouping patients.The correlation of above three indexes with clinical parameters such as sex,serum calcium(Ca),β2-microglobulin(β2-MG),serum creatinine(Cr)in elderly MM patients were analyzed.The survival rates of patients with different levels of each index were compared.Univariate and multivariate analysis of the impact of clinical indicators on the prognosis of patients were performed.Results:The optimal cut-off values for PNI,CONUT score and FAR were 39.775,3.5 and 0.175,respectively,according to which the patients were divided into high and low group.Statistical analysis showed that there were significant differences in albumin level among different groups(all P＜0.05).In addition,there was a significant difference in hemoglobin between high-PNI group and low-PNI group(P＜0.05),while in sex distribution between high-FAR and low-FAR group(P＜0.05).The survival rate of elderly MM patients with increased PNI,decreased CONUT score and FAR was higher(all P＜0.05).Univariate and multivariate analysis showed that β2-MG,Cr,PNI,CONUT score and FAR were independent prognostic factors for elderly MM patients.Conclusion:PNI,CONUT score and FAR are related to some clinical indicators of elderly MM patients,and have an impact on the prognosis.

Objective:To analyze the clinical characteristics and prognosis of patients with CD5+diffuse large B-cell lymphoma(DLBCL).Methods:The clinical data of 161 newly treated DLBCL patients in Gansu Provincial Hospital from January 2013 to January 2020 were retrospectively analyzed.According to CD5 expression,the patients were divided into CD5+group and CD5-group.The clinical characteristics and prognosis of the two groups were statistically analyzed.Results:The median age of patients in CD5+group was 62 years,which was higher than 56 years in CD5-group(P=0.048).The proportion of women in CD5+group was 62.96％,which was significantly higher than 41.79％in CD5-group(P=0.043).The proportion of patients with IPI score＞2 in CD5+group was 62.96％,which was higher than 40.30％in CD5-group(P=0.031).Survival analysis showed that the median overall survival and progression-free survival time of patients in CD5+group were 27(3-77)and 31(3-76)months,respectively,which were both shorter than 30(5-84)and 32.5(4-83)months in CD5-group(P=0.047,P=0.026).Univariate analysis showed that advanced age,positive CD5 expression,triple or double hit at initial diagnosis,high IPI score and no use of rituximab during chemotherapy were risk factors for the prognosis of DLBCL patients.Further Cox multivariate regression analysis showed that these factors were also independent risk factors except for advanced age.Conclusion:CD5+DLBCL patients have a worse prognosis than CD5-DLBCL patients.Such patients are more common in females,with advanced age and high IPI score,which is a special subtype of DLBCL.

Objective:To analyze the clinical characteristics and occurrence of thrombotic/bleeding events of patients with myeloproliferative neoplasm(MPN),and explore the main influencing factors,and create a risk prediction.Methods:The clinical data of 126 MPN patients with BCR-ABL fusion gene negative in the Department of Hematology of Gansu Provincial Hospital from January 2016 to September 2021 were collected,and their clinical characteristics,occurrence of thrombotic/bleeding events and main influencing factors were analyzed and summarized retrospectively.Then,a risk prediction model for thrombotic/bleeding events in MPN patients was constructed.Results:Among 126 MPN patients,50 patients(39.7％)had experienced thrombotic/bleeding events,including 44 patients(34.9％)with thrombotic events and 6 patients(4.8％)with bleeding events.Among thrombotic diseases,cerebral thrombosis was the most common(23/44,52.3％),followed by 9 cases of limb artery thrombosis mainly characterized by finger and toe tip artery ischemia,occlusion and gangrene(9/44,20.5％).Bleeding events included intracerebral hemorrhage and gastrointestinal hemorrhage.Univariate analysis showed that hypertension,hyperhomocysteinemia,white blood cell(WBC)≥10 × 109/L,hematocrit(HCT)≥49％,platelet(PLT)≥600 × 109/L and JAK2V617F gene mutation were risk factors for thrombotic/bleeding events in MPN patients,while CALR gene mutation was a protective factor.Multivariate analysis showed that hypertension and PLT ≥ 600 × 109/L were independent risk factors for thrombotic/bleeding events in MPN patients.The goodness of fit of the constructed risk prediction model was 0.872,and the area under the ROC curve was 0.838.The model was validated with clinical data,the sensitivity,specificity and accuracy was 78.85％,87.83％and 84.13％,respectively.Conclusion:The risk of thrombotic/bleeding events in MPN patients with high WBC count,hypertension and hyperhomocysteinemia is higher.Controlling hypertension and hyperhomocysteinemia and reducing WBC and PLT counts are helpful to prevent thrombotic/bleeding events and improve the life quality of patients.

OBJECTIVE: To retrospectively analyze the clinical efficacy of anterior cruciate ligament (ACL) reconstruction combined with anterolateral complex repair and ACL reconstruction combined with ALL reconstruction in the treatment of anterior cruciate ligament injuries with high-grade pivot shift. METHODS: From January 2018 to June 2022, 49 patients combined ACL and ALL injuries with high-grade pivot shift were retrospectively studied from three hospitals, 29 of them underwent ACL reconstruction with anterolateral complex repair (repair group), including 23 males and 6 females with an average age of (27.5±4.8) years old, ranged from 20 to 37 years old;the injured sides were 13 on the left and 16 on the right, and 11 patients were suffered with meniscus injury. The other 20 patients underwent ACL and ALL reconstruction (reconstruction group) including 17 males and 3 females with the mean age of (27.1±4.5) years old, ranged from 20 to 38 years old;the injured sides were 8 on the left and 12 on the right, and 6 patients were suffered with meniscus injury. Knee stability (pivot shift test, KT-2000), range of motion, knee function (Lysholm scoring scale, Cincinnati sports activity scale (CSAS) scoring scale, and Tegner activity level score between two groups were compared. RESULTS: A total of 49 patients were followed up, the repair group receiving 13 to 20(15.3±1.8) months and the reconstruction group receiving 12 to 21(16.0±2.2) months. There was no statistically significant difference in the preoperative pivot shift test grading distribution between two groups (P>0.05). At the last postoperative follow-up, there were 24 patients with grade 0 and 5 patients with grade 1 in the repair group, and there were 18 patients with grade 0 and 2 patients with grade 1 in the reconstruction group, there is no significant difference in the distribution of axial shift test grading between two groups(P>0.05). The preoperative KT-2000 tibial displacement of two groups were (9.39±0.77) mm (repair group) and (9.14±0.78) mm (reconstruction group) respectively, with no statistically significant difference (P>0.05). At the final postoperative follow-up, there were 24 patients with KT-2000 tibial displacement <3 mm and 5 patients with 3 to 5 mm in the repair group, while 18 patients with <3 mm and 2 patients with 3 to 5 mm in the reconstruction group, KT-2000 tibial displacement distribution of two groups was no significant difference (P>0.05), but the KT-2000 tibial displacement in the reconstruction group (1.30±0.86) mm was significantly smaller than that in the repair group (1.99±1.11) mm (P<0.05). The final postoperative follow-up range of motion of the contralateral side knee between two groups was no significant difference (P>0.05). The range of motion of the suffering knee in the repair group was less than that in the reconstruction group (P<0.05). There was no significant difference in preoperative Lysholm and CSAS scores between two groups (P>0.05). At the final postoperative follow-up, both groups showed significant improvement in Lysholm and CSAS scores, while the Lysholm and CSAS scores of the reconstruction group were better than those of the repair group, and the difference was statistically significant (P<0.05). Significant differences was found in Tegner scores between two groups, which 16 patients in the repair group returned to their pre-injury activity level, and 17 patients in the reconstruction group returned to their pre-injury level (P<0.05). CONCLUSION Compared to anterolateral complex repair, combined ACL and ALL reconstruction in the treatment of ACL injuries with high-grade pivot shift results in better knee joint function and stability. This is advantageous in reducing the risk of ACL reconstruction failure.

OBJECTIVE: To analyze the clinical features and prognosis of patients with Castleman's disease (CD) and improve the diagnosis and treatment of CD. METHODS: Clinical data of patients diagnosed with CD by pathological biopsy in Gansu Provincial Hospital from January 2009 to November 2020 were retrospectively analyzed. According to clinical classification, the patients were divided into two groups: UCD (unicentric CD) group (n=20) and MCD (multicentric CD) group (n=9). The clinical manifestations, laboratory examination, treatment regimens, pathological examination and follow-up data were statistically analyzed. RESULTS: There were no significant differences in average age and gender ratio between UCD group and MCD group. In UCD patients, 80.0% were hyaline vascular type, and 20.0% were plasma cell type. In MCD patients, 33.3% were hyaline vascular type, 55.6% were plasma cell type, and 11.1% were mixed type. There was significant difference in pathological classification between the two groups (P=0.039). The UCD patients usually presented asymptomatic single lymph node enlargement with mild clinical symptoms, while the MCD patients were characterized by multiple superficial and deep lymph node enlargement throughout the body. The incidences of asthenia, splenomegaly, serous effusion in MCD group were higher than those in UCD group (P<0.05). Meanwhile, the incidences of anemia, hypoproteinemia, increased ESR, elevated serum globulin and elevated β₂-microglobulin were significantly higher than those in UCD group too (P<0.05). There was no significant difference in the incidences of abnormal WBC, PLT and elevated LDH between the two groups (P>0.05). Among 20 patients with UCD, 13 cases reached complete remission (CR), 1 case achieved partial remission (PR). Among 9 patients with MCD, 3 cases received CR and 4 cases received PR. CONCLUSION Patients with CD requires pathological examination for diagnosis. Patients with UCD show mild clinical symptoms, good surgical treatment effect and good prognosis. Patients with MCD have diversified clinical manifestations and relatively poor prognosis, and these patients require comprehensive treatment.

Objective: To evaluate the efficacy and safety of Beijing Children's Hospital (BCH) modified hemophagocytic lymphohistiocytosis (HLH) 04 regimen in the treatment of childhood HLH. Methods: A retrospective cohort study was conducted. From January 2016 to December 2017, 110 children with HLH who were treated with the modified HLH-04 regimen (replacing dexamethasone with methylprednisolone during the induction period, reducing the dose and frequency of etoposide, and not using cyclosporine except for autoimmune-related HLH) at the Hematology Oncology Center of Beijing Children's Hospital were selected as the modified group, while 102 children treated with the standard HLH-04 regimen from January 2012 to December 2015 were selected as the control group. The early remission rate, survival rate and adverse reactions of two groups were compared. Rank sum test and chi square test were used for comparison between groups. Results: The age of onset in the modified group was 1.9 (1.1, 3.5) years, with 65 males and 45 females. The age of onset in the control group was 2.0 (1.2, 4.6) years, with 47 males and 55 females. No significant difference was found in age and gender between 2 groups (both P>0.05). Except for fibrinogen (1.3 (1.0, 1.7) vs. 1.1 (0.8, 1.4) g/L, Z=-2.67, P=0.008) and natural killer cell activity (13.9 (13.4, 16.3) % vs.14.9 (12.0, 16.1) %, Z=-2.34, P=0.028), there were no statistically significant differences in etiology, disease duration, first clinical presentation, or laboratory tests between 2 groups (all P>0.05). At 2 months and 3 years, there were no statistically significant differences in overall survival between 2 groups (84.5% (93/110) vs.76.5% (78/102), 78.2% (86/110) vs. 67.6% (69/102), χ²=2.28, 3.07, P=0.131, 0.080). The first 3 weeks were the most common time for bone marrow suppression in the modified group, with a lower incidence than in the control group (47.3% (52/110) vs. 62.7% (64/102), χ²=5.11, P=0.024). The modified group had a lower rate of fungal infections than the control group (3.6% (4/110) vs. 13.7% (14/102), χ²=6.93, P=0.008). Compared with the control group, fewer children in the modified group died as a result of side effects from chemotherapy (8.0% (2/25) vs.30.3% (10/33), χ²=4.31, P=0.038). Conclusion: The BCH modified HLH-04 regimen reduced the intensity of chemotherapy, with overall efficacy no worse than the standard HLH-04 regimen, and significantly reduced the rate of chemotherapy-related myelosuppression, fungal infection and mortality.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

OBJECTIVE: To analyze the influence of serum homocysteine (Hcy) levels to the prognosis of newly diagnosed multiple myeloma (MM) patients, and to explore related factors affecting the prognosis of the patients. METHODS: The clinical pathological data of 180 newly diagnosed MM patients treated in our hospital from March 2013 to February 2015 were collected, and the patients were divided into high and low Hcy groups based on the median Hcy. The survival curves of the patients in the two groups were drawn to compare the differences of the survival; univariate and multivariate survival analysis was used to observe the influence of serum cysteine to the prognosis of newly diagnosed MM patients; the clinicopathological data of the patients with high and low Hcy in the two groups was compared, Pearson test was used to further analyzes the relationship between Hcy and different factors, and explores the related factors of Hcy affecting the prognosis of the patients. RESULTS: The median survival times of patients in the high and low Hcy groups were 32 (5-59) and 41 (7-71) months, respectively. The 3-year survival rate of the patients in high Hcy group was significantly lower than those in low Hcy group, and the difference shows statistically significant (P<0.05). The results of univariate survival analysis showed that the OS of newly diagnosed MM patients whom with advanced age, high bone disease grade, high-level bone marrow plasma cell count, LDH, C-reactive protein, Cr, β CONCLUSION Serum Hcy level has a correlation trend with the survival of newly diagnosed MM, which is affected by factors such as Hb.

[Objective]To determine the relationship between maternal serum IL-1, IL-6, IL-8, TNF-a and CRH levels and preterm labor in asymptomatic women at 24 to 28 weeks' gestation. [Methods] We performed a prospective cohort study from January 2015 to December 2017 for asymptomatic women at 24 to28 weeks' gestation and maternal serum. According to the pregnancy outcome, 100 cases of preterm labor were selected as experimental group and another 100 cases of term labor as control group. The levels of serum IL-1, IL-6, IL-8, TNF-a and CRH were measured by ELISA. The partial membranes of all cases were examined pathologically after labor. [Results] The levels of serum IL-1, IL-6 and IL-8 in preterm labor group were significantly higher than those in the control group (P <0.05). The levels of serum IL-6and IL-8 in preterm labor with chorioamnionitis were significantly higher than those without chorioamnionitis and term labor (P < 0.05). The level of IL-1 in preterm labor without chorioamnionitis was significantly higher than that of term labor (P<0.05). The levels of serum TNF-a and CRH had no difference between the groups (P>0.05). Receiver-operating characteristic curves demonstrated that serum IL-1, IL-6 and IL-8 predicted preterm labor. The area under the curve (AUC) of IL-1 was 0.843. The AUC of IL-6 was0.675 and IL-8 was 0.55. [Conclusion] Maternal serum IL-1, IL-6 and IL-8 in asymptomatic women at24 to 28 weeks' gestation are useful markers for prediction of preterm labor.
