Abstract	Objective: To explore the lumbar spine biomechanics of graded ventral facetectomy and determine the appropriate extent of resection for foraminoplasty. Patients and methods: We retrospectively measured several radiological parameters of superior articular process (SAP) and bony intervertebral foramen in computed tomography scans of 170 lumbar vertebral discs. The intact finite element (FE) spine of L2-sacrum was modified to simulate foraminoplasty with two typical graded ventral facetectomy methods (Method Ⅰ: basal part resection of SAP; Method Ⅱ: apical part resection of SAP) to explore the biomechanical effects under different physiological motions. Results: Examination of the radiological parameters of the bony intervertebral foramen indicated that they were generally narrower than the diameters of commercially available working cannulas. Some of these parameters showed gender differences. The biomechanical evaluation indicated that the range of motion increased gradually with the expansion of the resection extent, and the differences compared to the intact spine at the same level were greater in Method I than in Method Ⅱ. Conclusions: The appropriate ventral resection extent of the basal part of the SAP (Method I) was 4 mm, 3 mm, and 3 mm on the lateral view at L3-L4, L4-L5, and L5-S1, respectively. The appropriate ventral resection extent of the apical part of the SAP (Method II) were 10 mm, 6 mm and 6 mm on the lateral view at L3-L4, L4-L5, and L5-S1, respectively. Extensive resection of foraminoplasty may destabilize lumbar motion segments.

Abstract	Regulator of Chromosome Condensation 1 (RCC1), a Guanine Nucleotide Exchange Factor (GEF) for the small Ran GTPase (Ran-GTP), is localized on chromatin in the nucleus where it mediates the generation of Ran-GTP. The production of Ran-GTP by RCC1 is critical for nuclear envelope formation, nucleocytoplasmic transport, DNA replication, and chromosome-induced mitotic spindle assembly. Most of the previous studies on RCC1 were carried out in mammalian cells. Only few studies on RCC1 in plant cell have been reported. Here we present an investigation on the identification of RCC1 and its location in wheat (Triticum aestivum L.) somatic cells during mitosis using immunoblotting and immunofluorescence. It was assumed that RCC1 was richer in chromatin than the surrounding cytoplasm throughout mitosis. Compared with white light, enhanced UV-B radiation greatly reduced the content of RCC1 (immunoblotting) and its fluorescence intensity. When RCC1 was absent, laser scanning confocal microscope detected the abnormal chromosomes. The results indicate that the participation of RCC1 in cell cycle provides theoretical ground for revealing the mechanism of abnormal mitosis caused by enhanced UV-B radiation and are of practical significance for agricultural production.

Abstract	In Pelton turbine, two-phase homogeneous model is the fundamental base to investigate the flow inside the turbine. Meanwhile, flow pattern in section of the distributor and bifurcation pipe produces the secondary flow which influences the shape of the jet downstream 6 nozzles. This paper numerically investigated the dynamic process using CFX commercial code under different operating conditions. Volume of Fluid(VOF) model was used to capture the air/water interface. This work focuses on the jet bifurcation problem which can seriously influence the Pelton turbine performance and furthermore it is not yet investigated in hydraulic research. Results indicate that the shape of the distributor induces the secondary flow and Dean vortex structure which are symmetric with the central horizontal plane of the pipe and nozzles. On the other hand, this sequence of vortex develops and transits along the flow and finally affects the shape of jet. Effect of secondary flow in the distributor stretches the jet flow in vertical direction and compress it in horizontal direction. Meanwhile, bifurcating phenomenon is observed outside the nozzle which is also obtained in classical experimentations. This study reveals that the secondary flow is important to be taken into consideration to optimize the performance of Pelton turbine.

Abstract	Objective: To compare occurrence and curative effect of interstitial pneumonia (IP) of patients with malignant hematologic disease after related HLA-haploidentical peripheral blood stem cell transplantation without T-cell depletion (RHNT-PBSCT) and non T cell-depleted HLA-matched sibling peripheral blood stem cell transplantation (MSNT-PBSCT). Methods: 109 patients with malignant hematologic disease as the research cases received RHNT-PBSCT from January 2006 to December 2014, which were compared with 125 patients treated with MSNT-PBSCT during the same period to determine the occurrence of IP and curative effect produced by ganciclovir and joint adrenal glucocorticoids. Results: The incidences of IP in RHNT-PBSCT and MSNT-PBSCT groups were 15.60%(17/109) and 13.60%(17/125) (P=0.150), respectively; both the effective rates were 76.47%(13/17) (P=0.536), the difference was not statistically significant. Single factor analysis showed that acute graft versus host disease was a risk factor for the occurrence of IP after RHNT-PBSCT (P=0.001). Conclusion: The incidence of IP in patients with malignant hematologic disease after RHNT-PBSCT didn' t increase when compared with patients after MSNT-PBSCT. The curative effects of the two groups were equivalent after priority to ganciclovir and joint adrenal glucocorticoids.

Abstract	Objective: To estimate the prevalence of anemia in urban community dwelling elderly population. Methods: This study was a cross-sectional survey of prevalence of anemia in randomly selected community dwelling residents aged over 65 years in Beijing. Anemia was defined as hemoglobin concentration less than 130 g/L in men and 120 g/L in women. Results: The hemoglobin concentration was (135.65±14.48) g/L in total of 1 947 eligible participants and was much higher in men than in women [(142.56±15.56) g/L vs (130.95±11.53) g/L, P<0.001]. There were 288 (14.8%) patients with anemia, including 16.3%(129/789) in men and 13.7%(159/1 158) in women. The prevalence of anemia increased significantly with age, which was 7.6% in 65-69 years, 10.8% in 70-74 years, 18.8% in 75-79 years and 24.1% over 80 years (P<0.001). Two hundred and seventy-nine (96.9%) subjects were mild anemia, 8 (2.8%) moderate, only 1 subject (0.3%) severe. Unexplained anemia was predominant, which accounted for 63.2%. Only 16.7% people were diagnosed as nutritional anemia, renal anemia 5.2%, anemia of chronic disease (ACD) 12.2%. There were 2.4% people with overlapped renal anemia and ACD. Compared with non-anemic subjects, more subjects with unexplained anemia represented macrocytosis (7.1% vs 3.2%, P=0.007). Conclusions: Anemia is a common health problem in urban community dwelling elderly population. Most subjects have anemia with unknown origin. Further investigation is needed to explore the mechanism and related factors of elderly anemia.

Abstract	OBJECTIVE: To explore the clinical characteristics of patients with different severity in the early outbreak of COVID-19, hoping to provide reference for clinical diagnosis and treatment METHODS: We retrospectively analyzed the clinical data of 95 COVID-19 patients in Wuhan Red Cross Hospital of China from January 17 to February 13, 2020 All patients were investigated with epidemiological questionnaires Outcomes were followed up until April 1, 2020 RESULTS: There were 53 males and 42 females, aged 22-84 years (mean 57 3 years) Clinical classification included 54 cases of common type, 27 cases of severe type, and 14 cases of critical type Six patients had been exposed to the local Huanan seafood market There were 38 clusters of COVID-19, including 27 family clusters and 11 work unit clusters Common symptoms included fever (86 (90 5%) of 95), cough (73 (76 8%)), and fatigue (50 (52 6%)) Laboratory findings showed that the most common abnormalities were lymphopenia (75 (78 9%)), elevated D-dimer (60 (63 2%)), and elevated C-reactive protein (56 (58 9%)) on admission All patients had abnormal chest computed tomography, showing patchy shadows or ground-glass opacities Severe and critical cases were older, more likely to have shortness of breath, more likely to have underlying comorbidities, and more likely to have abnormal laboratory findings than common cases The prognosis of patients with different degrees of severity was significantly different All common and severe patients (100%) were cured and discharged from the hospital, while 10 (71 4%) of 14 critical patients died CONCLUSIONS: COVID-19 has fast transmission speed and high pathogenicity We must assess the severity of the disease and take corresponding treatment measures as early as possible
