RESUMEN
A retrospective analysis was conducted on a MonoMAC syndrome case admitted in October 2022 to the First Affiliated Hospital of Zhejiang University School of Medicine. The patient, a 16-year-old female with a history of persistent monocytopenia and mild anemia for several years, experienced recurrent symptoms of cough, expectoration, and fever, leading to multiple visits to the hospital. The diagnosis of MonoMAC syndrome was confirmed through comprehensive assessments including routine blood tests, pathogen metagenomic sequencing, lung and bone marrow biopsies, and next-generation sequencing of peripheral blood. The patient underwent haploidentical hematopoietic stem cell transplantation, with a smooth course of transplantation, achieving neutrophil engraftment on + 16 d and platelet engraftment on + 17 d, eventually restoring normal monocyte and NK cell counts. MonoMAC syndrome patients often initially present with infectious symptoms, and the diagnosis can be established based on significant monocytopenia in routine blood tests, history of non-tuberculous mycobacterial infections, and GATA2 germline mutations. Allogeneic hematopoietic stem cell transplantation may be required for some patients to improve their prognosis.

Objective: To investigate long-term health-related quality of life (HRQoL) and related factors in children with severe hemophilia A (HA) who received regular low-dose prophylaxis. Methods: Clinical data of severe HA children who began to receive regular low-dose coagulation factor â § (Fâ §) prophylaxis in Peking Union Medical College Hospital from January 1, 2008 to December 31, 2011 were retrospectively enrolled. The longest last follow-up period was May 31, 2023. The attendance of school or work and daily physical activity during the last follow-up were investigated. The patients were divided into full attendance group and incomplete attendence group according to attendance. The patients were divided into into exercise attainment group (reached Chinese sports recommendation) and exercise nonattainment group according to the exercise status. Barthel score was used to assess activities of daily living and Haemo-QoL was used to assess quality of life. Long-term HRQoL for children aged 8-16 years and patients aged 17 years and above were assessed using Haemo-QoL SF and Haem-A-QoL versions, respectively. Spearman correlation analysis was used to examine the correlation between treatment conditions and Haemo-QoL scores. Results: A total of 22 cases were enrolled, the prophylaxis initiation age ranged from 1.8-17.9 (10.4±3.8) years old. The average prophylactic Fâ § dose during low-dose prophylaxis was 24.2 U/kg per week and the follow-up time was 6.3-15.1 (9.6±2.8) years. At the last follow-up, the age of the patients was (20.2±5.4) years, of which 14 (63.6%) were adults over 18 years old. There were 15 patients in the full attendance group and 7 patients in the incomplete attendence group. Compared with the full attendance group, the incomplete attendence group had a smaller preventive treatment dose [M(Q1, Q3), (28.4±11.1) vs (15.3±3.7) U/kg, P=0.012], shorter preventive treatment time [148. 1 (18.6, 346.5) vs 48.0 (32.0, 156.9) weeks, P=0.017], and higher annual joint bleeding rate (AJBR) [12.5 (6.0, 22.3) vs 14.2 (13.2, 17.8) times, P=0.017]. There were 7 cases in the exercise attainment group and 15 cases in the exercise nonattainment group. Compared to the exercise attainment group, the exercise nonattainment group had shorter preventive treatment time[313. 7 (156.9, 366.0) vs 48.0 (16.5, 108.9) weeks, P=0.006], a higher AJBR [7.0 (5.1, 10.0) vs 23.3 (12.5, 29.8), P=0.003] and a higher hemophilia joint health score (HJHS) [9.0 (2.0, 15.5) vs 23.0 (12.0, 27.8), P=0.014]. Barthel score showed 81.8% (18 cases) of the patients' living ability was not influenced by the illness. In Haemo-QoL score, the total score of Haemo-QoL SF in 7 cases was (47.6±17.0) scores, the total score of Haem-A-QoL in 15 cases was (45.2±22.6) scores. The daily activity dimension of the Haem-A-QoL score was the lowest [38.2 (10.9, 45.5) scores], which was positively correlated with the starting age of prophylactic initiation (r=0.501, P=0.057), and negatively correlated with the duration of prophylaxis (r=-0.545, P=0.036). Conclusions: Regular low-dose prophylaxis could improve the long-term HRQoL of some children with severe HA, and children with higher prophylactic doses and longer prophylactic treatment time have higher quality of life.

Objective: To analyze the epidemic characteristics of mumps in people aged 0-14 years in Jiangxi Province and the vaccination situation of mumps-containing vaccines (including mumps vaccines) from 2015 to 2022 to provide a scientific basis for the prevention and control of mumps epidemic in Jiangxi Province. Methods: The mumps epidemic situation and mumps vaccination data in Jiangxi Province from 2015 to 2022 were obtained from Chinese Disease Prevention and Control Information System and Jiangxi Immunization Program Information System and were analyzed using descriptive epidemiological methods. The chi-square test, cluster analysis, and Cochran-Armitage trend test were used for statistical analysis. Results: From 2015 to 2022, a total of 40 734 cases of mumps were reported in people aged 0-14 in Jiangxi Province, with an annual average reported incidence rate of 53.69/100 000, and the peak of incidence occurred in aged 6-7 years group, and the reported incidence rate was 86.43/100 000. The high incidence seasons in 2015-2019 were summer and winter, and there was no significant high incidence season in 2020-2022. Mumps outbreaks mainly occurred in Shangrao, Ganzhou, and Ji'an, and the outbreak sites were mainly reported primary schools. From 2015 to 2019, the 1-year group was the primary age group for vaccination against mumps, while from 2020 to 2021, it was 0 and 1-year groups. Conclusions: From 2015 to 2022, the incidence of mumps in the population aged 0-14 in Jiangxi Province showed a downward trend, and the peak of incidence occurred in age group 6-7 years. It is suggested to continue to strengthen the coverage rate of 2 doses of mumps vaccination for school-age children and, simultaneously, strengthen the monitoring and prevention of mumps in key places to avoid outbreaks.

Objective: To analyze the efficacy and safety of first-line treatment with an anti-CD38 monoclonal antibody regimen for primary plasma cell leukemia (pPCL). Methods: Patients diagnosed with pPCL from December 1st, 2018 to July 26th, 2023, receiving first-line treatment of anti-CD38 monoclonal antibody-based regimens across multiple centers including Peking University People's Hospital, Fuxing Hospital of Capital Medical University, Qingdao Municipal Hospital, Shengjing Hospital of China Medical University, Handan Central Hospital, the First Affiliated Hospital of Harbin Medical University, the Fourth Hospital of Hebei Medical University and General Hospital of Ningxia Medical University were consecutively included. A total of 24 pPCL patients were included with thirteen being male and eleven being female. The median age [M(Q1, Q3)] was 60 (57, 70) years. Patients were grouped according to peripheral blood plasma cell (PBPC) percentage [5%-19% (n=14) vs ≥20% (n=10)]. Last follow-up date was September 26th, 2023. The median follow-up period was 9.1 (4.2, 15.5) months. Patients' data related with clinical baseline characteristics, efficacy, survival and safety were retrospectively collected. Cox proportional hazards regression model was used to analyze risk factors associated with survival. Results: Among 24 pPCL patients, 16 (66.7%) patients had anemia at diagnosis, 13(54.2%) patients had thrombocytopenia, 8 (33.3%) patients had a baseline estimated glomerular filtration rate (eGFR)<40 ml·min-1·(1.73m2)-1, 13 (54.2%) patients had elevated lactate dehydrogenase (LDH) levels. The median PBPC percentage was 16% (8%, 26%) . Fluorescence in situ hybridization testing indicated that patients harboring 17p deletion, t(4;14) or t(14;16) were 6 (25.0%), 4 (16.7%) and 4 (16.7%), respectively. The overall response rate was 83.3% (20/24). The median progression-free survival (PFS) was 20.5 (95%CI: 15.8-25.2) months, and the median overall survival (OS) was not reached. Estimated 1-year and 2-year PFS and OS rates were 75.0% and 89.1%, 37.5% and 53.4%, respectively. The median PFS and OS for patients with PBPC percentages 5%-19% and≥20% were not reached and 20.5 (95%CI:15.7-25.3) months, 17.8 months and not reached, respectively. There was no significant statistical difference of PFS and OS between two groups (all P>0.05). Multivariate Cox regression analysis showed that 1p32 deletion was the risk factor associated with PFS (HR=7.7, 95%CI: 1.1-54.9, P=0.043). Seventeen patients (70.8%) developed grade 3-4 hematologic toxicities. Twelve patients (50.0%) developed grade 3-4 thrombocytopenia. Sixteen patients (66.7%) developed infection. All hematologic toxicities and infections were improved after supportive treatment. Conclusion: First-line treatment with anti-CD38 monoclonal antibody-based therapy for pPCL is effective and safe.

Objectives: Microvascular obstruction (MVO) is a specific cardiac magnetic resonance (CMR) imaging feature in patients with acute myocardial infarction. The purpose of this study was to elucidate the predictive value of MVO in left ventricular adverse remodeling after primary percutaneous coronary intervention (PCI) in patients with acute ST-elevation myocardial infarction (STEMI). Methods: A total of 167 patients with STEMI undergoing primary PCI in the Chinese PLA General Hospital from 2016 to 2020 were enrolled in this prospective cohort study, the average age of study patients was 57±10 years old, with 151 males (90.4%) and 16 females (9.6%). The patients were divided into the MVO group (n=81) and non-MVO group (n=86) according to the presence or absence of MVO on CMR imaging, respectively. The primary endpoint of the study was the occurrence of left ventricular adverse remodeling, which was defined as an increase in left ventricular end diastolic volume (LVEDV) by >20% at 6 months after primary PCI compared with the baseline. Patients who completed follow-up were diagnosed as left ventricular adverse remodeling or no left ventricular adverse remodeling according to CMR. The baseline data, perioperative data, and related data of end points were compared between the MVO group and non-MVO group. Finally, the predictive value of MVO in left ventricular adverse remodeling was calculated by receiver operating characteristic curve analysis. Results: In the baseline data, preoperative thrombolysis in myocardial infarction (TIMI) flow (χ2=13.74, P=0.003) and postoperative TIMI flow (χ2=14.87, P=0.001) were both obviously decreased in the MVO group. After 6 months of follow-up, the incidence of left ventricular adverse remodeling in the MVO group was significantly higher than that in the non-MVO group [37.0%(27/73) vs. 18.9%(14/74), χ2=5.96, P=0.015]. The left ventricular end systolic volume at 6 months post infarction in the MVO group was significantly larger than that in the non-MVO group [(94±32) vs. (68±20) ml, t=-5.98, P<0.001], as well as the LVEDV [(169±38) vs. (143±29) ml, t=-4.74, P<0.001]. Receiver operating characteristic curve showed that the area under the curve of MVO size for predicting left ventricular adverse remodeling was 0.637. Conclusion: The risk of left ventricular adverse remodeling is significantly increased in patients with MVO after primary PCI for acute STEMI.

Objective: To predict and analyze the incidence trend of mumps using the Autoregressive integrated moving average model (ARIMA) in Jiangxi Province. Methods: The ARIMA was used to model the number of mumps cases per month from 2015 to 2019 in Jiangxi Province. The number of mumps cases in 12 months was predicted and was compared with the actual reported cases in 2020, 2021, and 2022, respectively. Results: The optimal model was ARIMA (0,2,1)(1,2,0)12. The predicted number of cases was significantly higher than that reported in 2020, 2021 and 2022. The number of reported cases of mumps in 2020, 2021, and 2022 decreased by 54.02%, 63.40%, and 66.09% compared with the forecast. Conclusions: From 2020 to 2022, the reported incidence of mumps in Jiangxi Province was significantly lower than the predicted incidence. Considering that it was related to non-drug intervention measures and changes in immunization strategies, it was suggested to strengthen mumps surveillance further to better cope with the epidemic situation of mumps.

Objective: The purpose of this study was to assess the safety and efficacy of a second allogeneic hematopoietic stem cell transplantation (allo-HSCT) with reduced-intensity conditioning (RIC) in patients with hematological malignancies who had relapsed after the first allo-HSCT. Methods: Between April 2018 and June 2021, 44 patients with hematological malignancies (B-ALL 23, T-ALL/T-LBL 4, AML15, and MDS 2) were enrolled and retrospectively examined. Unrelated donors (n=12) or haploidentical donors (n=32) were used. Donors were replaced in all patients for the second allo-HSCT. Hematological and immunological germline predisposition genes and hematopoietic and immune function tests were used to select the best-related donor. Total body irradiation (TBI) /fludarabine (FLU) -based (n=38), busulfan (BU) /FLU-based (n=4), total marrow irradiation (TMI) /FLU-based (n=1), and BU/cladribine-based (n=1) were the RIC regimens used. For graft versus host disease (GVHD) prevention, cyclosporine, mycophenolate mofetil, short-term methotrexate, and ATG were used. Eighteen (40.9%) of 44 patients with gene variations for which targeted medications are available underwent post-transplant maintenance therapy. Results: The median age was 25 years old (range: 7-55). The median interval between the first and second HSCT was 19.5 months (range: 6-77). Before the second allo-HSCT, 33 (75%) of the patients were in complete remission (CR), whereas 11 (25%) were not. All patients had long-term engraftment. The grade â ¡-â £ GVHD and severe acute GVHD rates were 20.5% and 9.1%, respectively. Chronic GVHD was found in 20.5% of limited patterns and 22.7% of severe patterns. CMV and EBV reactivation rates were 29.5% and 6.8%, respectively. Hemorrhage cystitis occurred in 15.9% of cases, grade â or â ¡. The 1-yr disease-free survival (DFS), overall survival (OS), and cumulative recurrence incidence (RI) rates of all patients were 72.5% (95% CI, 54.5%-84.3%), 80.6% (95% CI, 63.4%-90.3%), and 25.1% (95% CI, 13.7%-43.2%), respectively, with a median follow-up of 14 (2-39) months. There were eight deaths (seven relapses and one infection). The rate of non-relapse mortality (NRM) was only 2.3%. The CR patients' 1-yr RI rate was significantly lower than the NR patients (16.8% vs 48.1%, P=0.026). The DFS rate in CR patients was greater than in NR patients, although there was no statistical difference (79.9% vs 51.9%, P=0.072). Univariate analysis revealed that CR before the second allo-HSCT was an important prognostic factor. Conclusion: With our RIC regimens, donor change, and post-transplant maintenance therapy, the second allo-HSCT in relapsed hematological malignancies after the first allo-HSCT is a safe and effective treatment with high OS and DFS and low NRM and relapse rate. The most important factor influencing the prognosis of the second allo-HSCT is the patient's illness condition before the transplant.

OBJECTIVE: To assess the safety and efficacy of Neuroform Atlas stent used in treatment of unruptured wide-neck intracranial aneurysms. METHODS: Clinical data of 62 patients with unruptured wide-neck intracranial aneurysms undergoing Neuroform Atlas stent-assisted coiling from August 2020 to September 2021 were retrospectively analyzed. There were 64 aneurysms in those 62 patients. Among them, 25 aneurysms were located at the bifurcation of M1 segment on middle cerebral artery, 16 at the anterior communicating artery, 10 at the C7 segment of internal carotid artery, 5 at the C6 segment of internal carotid artery, 4 at the apex of basilar artery, 3 at the A3 segment of anterior cerebral artery, and 1 at the M2 segment of middle cerebral artery. All the patients underwent Neuroform Atlas stent-assisted coiling, including 49 patients with single stent assisted coiling and 15 patients with dual stents assisted coiling (14"Y"style and 1"X"style). After the procedure, the immediate DSA was performed to evaluate the status of aneurysm occlusion and the parent artery patency. The clinical follow-up was performed 3 months after the operation and evaluated based on the modified Rankin Scale(mRS).DSA image was reviewed at 6 months after operation and Raymond grading scale was used to assess the status of aneurysm occlusion and the parent artery patency. RESULTS: A total of 62 patients with 64 aneurysms were all achieved technical success(100%).The immediate post-procedural Raymond scale was assessed, including Raymond â in 57 aneurysms(89.1%, 57/64), Raymond â ¡ in 6 aneurysms(9.3%, 6/64) and Raymond â ¢ in 1 aneurysm(1.6%, 1/64). The peri-procedural complications rate was 4.8%(3/62), 2 patients developed intraoperative thrombosis and 1 patient suffered from local subarachnoid hemorrhage. Among them, 55 patients obtained 3 months clinical follow-up after operation and all the patients had good outcomes (mRS≤2), 50 patients with 52 aneurysms were followed up with DSA 6 months after operation, including Raymond â in 45 aneurysms(86.5%, 45/52), Raymond â ¡ in 4 aneurysms(7.7%, 4/52) and Raymond â ¢ in 3 aneurysms(5.8%, 3/52). CONCLUSION: Neuroform Atlas stent for the treatment of unruptured wide-neck intracranial aneurysms has high safety and good efficacy, and has its advantages over other traditional stents.

OBJECTIVE: To investigate the diversity and composition of microflora in laboratory-reared Aedes albopictus at different developmental stages and larval habitat waters. METHODS: The larval habitat waters and different developmental stages of laboratory-reared A. albopictus were collected, and the V3 and V4 regions of the bacterial 16S rRNA gene were sequenced using Illumina Miseq next-generation sequencing. The abundance and diversity of the microflora were examined using alpha diversity index in A. albopictus at different developmental stages, and the difference in the microflora compositions was compared in A. albopictus at different developmental stages using principal component analysis (PCA). In addition, the species composition and relative abundance of microflora in A. albopictus at different developmental stages were described using histograms and Venn diagrams. RESULTS: A total of 16 phyla, 30 classes, 72 orders, 129 families and 224 genera of bacteria were detected in larval habitat waters and different developmental stages of A. albopictus. The highest bacterial diversity was seen in larval A. albopictus, with Chao index of 125.20 ± 30.48 and Shannon diversity index of 2.04 ± 0.39, which were comparable to those (Chao index of 118.52 ± 15.07 and Shannon diversity index of 2.15 ± 0.30) in larval habitat waters (t = 0.35 and -0.41, both P values > 0.05). The bacterial abundance and evenness were significantly greater in female adults than in male adults (Chao index: 42.50 ± 3.54 vs. 18.50 ± 2.13, t = 8.23, P < 0.05; Shannon diversity index: 1.25 ± 1.67 vs. 0.50 ± 0.05, t = 6.00, P < 0.05). Proteobacteria, Bacteroidota, Actinobacteriota and Finnicutes were four common phyla of bacteria at each developmental stage of A. albopictus, with Proteobacteria dominated at the pupal stage (90.36%), Bacteroidota dominated at the adult stage (46.01% in female adults and 86.11% in male adults), and Actinobacteriota dominated at the larval stage (32.10%). Elizabethkingia and Rahnella 1 were common dominant genera of bacteria at each developmental stage of A. albopictus, with Rahnellal as the major component at the pupal stage (87.56%), Elizabethkingia as the main component at the adult stage (46.01% in female adults and 86.11% in male adults, respectively), and Microbacteria as the dominant bacterial genus at the larval stage (12.11%). In addition, Delftia, Elizabethkingia, Romboutsia, Serratia, Rahnella 1, Enterococcus and Microbacterium were common genera of bacteria at each developmental stage of A. albopictus, with Edaphobaculum dominated at the larval stage (17.54%) and Sphingobacterium dominated in larval habitat waters (13.93%). CONCLUSIONS: There are differences in the composition of symbiotic bacteria at different developmental stages of A. albopictus; however, similar microflora diversity is maintained at the phylum level. The microflora diversity is comparable in larvae and larval habitat waters of A. albopictus.

AIM: To develop a split glomerular filtration rate (sGFR) prediction model based on unilateral renal volume parameters using three-dimensional (3D) computed tomography (CT) volumetry. MATERIALS AND METHODS: Clinical data (age, sex, height, weight, serum creatinine level [sCr], and sGFR measured by 99mTc-diethylene triamine pentaacetic acid nuclear renal scintigraphy with the double plasma sample method) of 67 healthy renal donors and 111 patients with hydronephrosis admitted from April 2016 to September 2021 were analysed. The split renal parenchymal volume (sRPV) and split renal calyces and pelvis volume (sRCPV) of 67 unilateral donor left kidneys and 111 hydronephrotic kidneys were measured. Statistical analysis of these parameters was performed to develop and validate the sGFR prediction model. RESULTS: sRPV (p<0.001), sRCPV (p=0.012), age (p=0.015), serum creatinine level (p=0.004), and weight (p=0.006) were significantly associated with the measured sGFR and were included in the sGFR prediction formula, which was constructed as: 68.710 + 0.093 × sRPV-0.041 × sRCPV-0.228 × W-0.219 × A-14.432 × sCr (r2 = 0.416; where A is age, W is weight). The paired difference of internal validation between the measured sGFR (42.34 ± 13.71 ml/min/1.73 m2) and the sGFR estimated by the prediction model (41.46 ± 8.99 ml/min/1.73 m2) was 0.879 ± 11.475 ml/min/1.73 m2 (p=0.492) with a 95% confidence interval of the mean difference of ±2.54 ml/min/1.73 m2. CONCLUSION: The proposed model based on sRPV and sRCPV parameters could be used for estimating split renal function of healthy renal donors and patients with hydronephrosis to some extent. Further studies are required to evaluate and rectify the model.

OBJECTIVE: To introduce an arthroscopic "inlay" Bristow procedure based on the Mortise-Tenon joint structure concept using suture button fixation, and to evaluate its clinical and radiology results postoperatively with a minimal 3-year follow-up. METHODS: A total of 56 patients who received arthroscopic "inlay" Bristow procedure with suture button fixation between June 2015 to June 2016 were eventually enrolled in this study. Radiological assessment on the 3D CT scan was performed preoperatively, immediately after operation, and postoperatively at the end of 3 months, 6 months and the final follow-up. Complications postoperatively were also recorded. RESULTS: A total of 56 patients were finally included in this study. The mean follow-up time was (36.1±3.7) months. Coracoid grafts (middle point) were positioned at about 4 o'clock (123.8°±12.3°) in the En-face view. In the axial view, 95% (53/56) of the grafts positioning were measured as flush, 5% (3/56) as medial. Bone union rate was 96.4% at the final follow-up. At the end of 3 months, 6 months, and the final follow-up, the length of the coracoid graft was 96.9%±4.9%, 91.9%±6.2%, and 91.6%±6.6% of the immediate postoperative length, respectively. Compared with the immediate postoperative length, the length measured at the end of 3 months shortened not significantly (t=2.12, P > 0.05). The coracoid graft shortened more pronouncedly 6 months postoperatively (t=4.98, P < 0.05) and then remained almost constant over time (t=-0.75, P > 0.05), with all grafted coracoid graft retaining more than 90% of their initial length by the 3-year follow-up. And new bone formation at the junction between the coracoid graft and glenoid neck in the axial view were obviously noted in 25 cases. The quantitative evaluation showed that the glenoid area in En-face view was significantly increased at the final follow-up than that immediately after surgery [(9.72±1.22) cm2 vs. (9.42±1.11) cm2]. No degenerative changes were noted on CT images in all the patients at the final follow-up. CONCLUSION: This study reported a series of "inlay" Bristow procedure with suture button fixation for recurrent shoulder dislocation, providing satisfactory union rate and excellent graft positioning. And using suture button fixation instead of screw can reduce osteolysis and complications related to hardware implantation. Moreover, the bone remodeling between the coracoid process and glenoid could be beneficial to restoring the anterior stability of shoulder joint in a long term follow-up.

RESUMEN
Objectives: To cross-sectionally analyze the clinical characteristics of primary antiphospholipid syndrome (PAPS) patients with thrombocytopenia, risk factors associated with thrombocytopenia, and risk of symptom recurrence in these patients. Methods: The inpatients with PAPS were retrospectively analyzed in Peking Union Medical College Hospital from 2009 to 2019. Using the collected clinical and laboratory data, the clinical characteristics and risk of symptom recurrence in the PAPS patients with thrombocytopenia were compared with those in the PAPS patients with normal platelet counts. Univariate and multivariate logistic regression analyses were performed to screen the risk factors for thrombocytopenia. Results: In this study, 127 patients with PAPS were enrolled, of which 36 (28.3% ) had thrombocytopenia, with a median age of 38 years, and 63.9% were female. In the thrombocytopenia group, the average platelet count was (58.9±27.0) ×10(9)/L, and the prevalence of thrombosis and morbid pregnancy was not significantly different from that in the normal platelet group. However, the thrombocytopenia group had higher incidence rate of autoimmune hemolytic anemia (19.4% vs 3.3% ) , livedo reticularis (16.7% vs 3.3% ) , chronic kidney disease (25% vs 8.8% ) and antiphospholipid antibodies triple positiveness (61.1% vs 37.4% ) , lower complement levels (C3 of 0.87 g/L vs 1.07 g/L, C4 of 0.12 g/L vs 0.18 g/L, P<0.05) , and higher adjusted Global APS Score (median score of 13 vs 9, P=0.037) than the normal platelet group. In multivariate logistic regression analysis, hypocomplementemia (OR value 5.032, 95% CI 3.118-22.095) is an independent risk factor for thrombocytopenia. Conclusions: In patients with PAPS, thrombocytopenia is mostly mild to moderate. Hypocomplementemia may be the independent risk factor for thrombocytopenia in PAPS patients. The PAPS patients with thrombocytopenia may have a higher risk of symptom recurrence.

Objective: To explore a modified CT scoring system, its feasibility for disease severity evaluation and its predictive value in coronavirus disease 2019 (COVID-19) patients. Methods: This study was a multi-center retrospective cohort study. Patients confirmed with COVID-19 were recruited in three medical centers located in Beijing, Wuhan and Nanchang from January 27, 2020 to March 8, 2020. Demographics, clinical data, and CT images were collected. CT were analyzed by two emergency physicians of more than ten years' work experience independently through a modified scoring system. Final score was determined by average score from the two reviewers if consensus was not reached. The lung was divided into 6 zones (upper, middle, and lower on both sides) by the level of trachea carina and the level of lower pulmonary veins. The target lesion types included ground-glass opacity (GGO), consolidation, overall lung involvement, and crazy-paving pattern. Bronchiectasis, cavity, pleural effusion, etc., were not included in CT reading and analysis because of low incidence. The reviewers evaluated the extent of the targeted patterns (GGO, consolidation) and overall affected lung parenchyma for each zone, using Likert scale, ranging from 0-4 (0=absent; 1=1%-25%; 2=26%-50%; 3=51%-75%; 4=76%-100%). Thus, GGO score, consolidation score, and overall lung involvement score were sum of 6 zones ranging from 0-24. For crazy-paving pattern, it was only coded as absent or present (0 or 1) for each zone and therefore ranging from 0-6. Results: A total of 197 patients from 3 medical centers and 522 CT scans entered final analysis. The median age of the patients was 64 years, and 54.8% were male. There were 76(38.8%) patients had hypertension and 30(15.3%) patients had diabetes mellitus. There were 75 of the patients classified as moderate cases, as well as 95 severe cases and 27 critical cases. As initial symptom, dry cough occurred in 170 patients, 134 patients had fever, and 125 patients had dyspnea. Reparatory rate, oxygen saturation, lymphocyte count and CURB 65 score on admission day varied among patients with different disease severity scale. There were 50 of the patients suffered from deterioration during hospital stay. The median time consumed for each CT by clinicians was 86.5 seconds. Cronbach's alpha for GGO, consolidation, crazy-paving pattern, and overall lung involvement between two clinicians were 0.809, 0.712, 0.678, and 0.906, respectively, showing good or excellent inter-rater correlation. There were 193 (98.0%) patients had GGO, 147 (74.6%) had consolidation, and 126(64.0%) had crazy-paving pattern throughout clinical course. Bilateral lung involvement was observed in 183(92.9%) patients. Median time of interval for CT scan in our study was 7 days so that the whole clinical course was divided into stages by week for further analysis. From the second week on, the CT scores of various types of lesions in severe or critically patients were higher than those of moderate cases. After the fifth week, the course of disease entered the recovery period. The CT score of the upper lung zones was lower than that of other zones in moderate and severe cases. Similar distribution was not observed in critical patients. For moderate cases, the ground glass opacity score at the second week had predictive value for the escalation of the severity classification during hospitalization. The area under the receiver operating characteristic curve was 0.849, the best cut-off value was 5 points, with sensitivity of 84.2% and specificity of 75.0%. Conclusions: It is feasible for clinicians to use the modified semi-quantitative CT scoring system to evaluate patients with COVID-19. Severe/critical patients had higher scores for ground glass opacity, consolidation, crazy-paving pattern, and overall lung involvement than moderate cases. The ground glass opacity score in the second week had an optimal predictive value for escalation of disease severity during hospitalization in moderate patients on admission. The frequency of CT scan should be reduced after entering the recovery stage.

The smoking cessation rate of 1 314 people at high risk of lung cancer in the area of lung cancer screening and early diagnosis and early treatment in Sichuan Province increased from 22.37% at baseline to 41.78% after screening (χ²=227.97, P<0.001), and the smoking amount of persistent smokers decreased from 20 cigarettes per day to 15 cigarettes per day (t=11.76, P<0.001). Those with positive results in lung cancer screening were more likely to quit smoking or continue to quit smoking. Male, younger age or lower education level would increase the risk of continuous smoking or relapse (P<0.05).

OBJECTIVE: The incidence of pulmonary adenocarcinoma locates first in all the malignant tumors in the world. At present, there are many diagnostic methods for pulmonary adenocarcinoma, but there are a few methods that are mature or have ideal application prospects. We aim to explore the role of VRK2 in the occurrence and development of pulmonary adenocarcinoma and its possible regulatory mechanism. PATIENTS AND METHODS: Western blot and qRT-PCR were performed to assess the expression of VRK2. Flow cytometry, Western blot, and Caspase-3 colorimetric assay Kit were used to evaluate the apoptosis level. The proliferation, migration, and invasion ability were measured via cell cycle assay, wound healing, and transwell invasion assay. Luciferase assay verified the relationship between VRK2 and miR-145-5p. The effect of FGD5-AS1 on tumorigenesis of glioma was detected by the xenograft nude mice model. RESULTS: VRK2 was significantly increased in tumor tissues and cell lines. Loss of VRK2 promoted apoptosis level and inhibited the proliferation, migration, and invasion in A549 cells via regulating the ERK1/2/AKT signal pathway. Luciferase assay reported that VRK2 could bind with miR-145-5p. The level of miR-145-5p was negatively correlated with the expression of VRK2 and involved in VRK2 regulating tumor progression. The tumor growth assay showed that the silencing of VRK2 inhibited tumorigenesis with the inactivating ERK1/2/AKT pathway. CONCLUSIONS: Knockdown of VRK2 inhibited the development of pulmonary adenocarcinoma via regulating the ERK1/2/AKT signal pathway by targeting miR-145-5p, which providing some novel experimental basis for clinical treatment of pulmonary adenocarcinoma.

Objective: To study the orthopedic treatment strategy for hemophilia complicated with musculoskeletal disorders as well as the peri-operative consumption of clotting factor. Methods: Total 338 orthopedic surgeries were performed for 261 patients, average age of 30.6 y (6-65 y) , with hemophilia between January 1996 and December 2019 at our institute. Two hundred and twenty-six patients presented with bleeds within the joints. Sixty-one patients presented with intramuscular bleeds, 45 presented with hemophilic pseudotumors, and six presented with miscellaneous complaints. Strategy of clotting factor replacement therapy was designed as per differences in the level of the operation procedure. Information regarding clinical manifestation, operative strategy, clotting factor consumption, and re-operation for complications was retrospectively recorded. The costs for multiple joint procedure and single joint procedure were studied. Results: We found that 270 of the 338 surgical procedures were major surgical procedures (79.9%) . There were 203 procedures of joint arthroplasty (60%) . Fourteen patients underwent reoperations for local recurrence (4.2%) . The average factor â § consumption before the surgery was 44.4 ± 8.1 IU/kg. The average Fâ § consumption within postoperative 2 weeks was 40 962 IU (647±177 IU/kg) . Seven type A hemophilic patients developed F â § inhibitor following the surgical procedure, with an average level of 13.7±11.2 BU/mL. Sixty-eight patients underwent multiple joint procedures under one anesthesia session (26%) . There was no significant difference in the factor consumption between the multiple joint procedure and single joint procedure. Conclusions: Surgical treatment was found to be effective for hemophilic arthropathy and lesion of the musculoskeletal apparatus, with the clotting factor replacement therapy. Multiple joint procedures under one anesthesia were more cost effective for patients with hemophilia, with less factor consumption than staged single joint procedure.
