Objective: To evaluate the advantages and safety of Plerixafor in combination with granulocyte colony-stimulating factor (G-CSF) in autologous hematopoietic stem cell mobilization of lymphoma. Methods: Lymphoma patients who received autologous hematopoietic stem cell mobilization with Plerixafor in combination with G-CSF or G-CSF alone were obtained. The clinical data, the success rate of stem cell collection, hematopoietic reconstitution, and treatment-related adverse reactions between the two groups were evaluated retrospectively. Results: A total of 184 lymphoma patients were included in this analysis, including 115 cases of diffuse large B-cell lymphoma (62.5%) , 16 cases of classical Hodgkin's lymphoma (8.7%) , 11 cases of follicular non-Hodgkin's lymphoma (6.0%) , 10 cases of angioimmunoblastic T-cell lymphoma (5.4%) , 6 cases of mantle cell lymphoma (3.3%) , and 6 cases of anaplastic large cell lymphoma (3.3%) , 6 cases of NK/T-cell lymphoma (3.3%) , 4 cases of Burkitt's lymphoma (2.2%) , 8 cases of other types of B-cell lymphoma (4.3%) , and 2 cases of other types of T-cell lymphoma (1.1%) ; 31 patients had received radiotherapy (16.8%) . The patients in the two groups were recruited with Plerixafor in combination with G-CSF or G-CSF alone. The baseline clinical characteristics of the two groups were basically similar. The patients in the Plerixafor in combination with the G-CSF mobilization group were older, and the number of recurrences and third-line chemotherapy was higher. 100 patients were mobilized with G-CSF alone. The success rate of the collection was 74.0% for one day and 89.0% for two days. 84 patients in the group of Plerixafor combined with G-CSF were recruited successfully with 85.7% for one day and 97.6% for two days. The success rate of mobilization in the group of Plerixafor combined with G-CSF was substantially higher than that in the group of G-CSF alone (P=0.023) . The median number of CD34(+) cells obtained in the mobilization group of Plerixafor combined with G-CSF was 3.9×10(6)/kg. The median number of CD34(+) cells obtained in the G-CSF Mobilization group alone was 3.2×10(6)/kg. The number of CD34(+) cells collected by Plerixafor combined with G-CSF was considerably higher than that in G-CSF alone (P=0.001) . The prevalent adverse reactions in the group of Plerixafor combined with G-CSF were grade 1-2 gastrointestinal reactions (31.2%) and local skin redness (2.4%) . Conclusion: The success rate of autologous hematopoietic stem cell mobilization in lymphoma patients treated with Plerixafor combined with G-CSF is significantly high. The success rate of collection and the absolute count of CD34(+) stem cells were substantially higher than those in the group treated with G-CSF alone. Even in older patients, second-line collection, recurrence, or multiple chemotherapies, the combined mobilization method also has a high success rate of mobilization.

Purpose: Spontaneous rupture is a potentially serious complication of liver cancer. A risk score was developed and validated for predicting spontaneous rupture based on a retrospective study. Methods: Multiple logistic regression analysis was used to study the relationship between clinical variables and spontaneous rupture. The independent rupture predictors were converted into a score based on the odds ratio. Predicted attributes of the developed scores were then verified using a dataset in 2019. Results: The incidence of spontaneous rupture was 5.5% from 2002 to 2019. A 10-point score (α-FP of ≥400 μg/L, 1; protrusion from liver surface, 2; ascites, 3; tumor size of >5 cm, 4) was derived for prediction of rupture and area under the receiver-operating characteristic curve was 0.9 (95% confidence interval, 0.87–0.92). When applying a cutoff value of 5 points or more, the specificity was 0.87 and the sensitivity was 0.84. A validation cohort consisting of 202 hepatocellular carcinoma patients reproduces the predictive, identification, and calibration characteristics. The observed rate of spontaneous rupture according to risk stratification of the score was 0.6% for those with a score of 0–4, 21.6% for a score of 5–7, and 36.4% for a score of 8–10 in the validation cohort. Conclusion Here, based on routine clinical data, we determine the factors that affect prognosis and propose an effective tool for predicting spontaneous rupture, which may be useful in guiding priority treatment of high-risk patients or clinical routine preventive treatment.

Objective:To determine the test-retest reliability of lumbar passive reposition accuracy for older people. Methods:A total of 58 healthy older people stood on an isokinetic dynamometer, and passively moved their trunk forward and backward to the target positions as accurately as possible. The targeted positions were set as flexion forward 15°, 30° and 60°, and flexion backward 15°. The absolute error (AE) was recorded. They were tested again a week latter. The intraclass correlation coefficient (ICC) and standard errors of measurement (SEM and SEM%) were calculated. Results:The ICC of AE was 0.699 to 0.833 for all the subjects, SEM was 1.18 to 3.26, and SEM% was 26.84% to 37.13%. For the men, the ICC was 0.462 to 0.818, SEM was 1.60 to 3.68, and SEM% was 36.37% to 48.78%. For the women, the ICC was 0.782 to 0.891, SEM was 1.48 to 2.71, and SEM% was 28.48% to 33.34%. Conclusions:Lumbar passive reposition accuracy is some reliable to assess the position sense for older people. However, there are too large errors for clinical measurement, which need further improvment.

Objective:To compare the difference in the onset time of the trunk muscles activity in individuals with and without nonspecific low back pain (NLBP) during upper limb flexion and abduction. Methods:From September to December, 2017, 21 patients with NLBP (NLBP group) and 21 volunteers (control group) participated in this study. Surface electromyography (sEMG) signals were recorded from the anterior deltoid, middle deltoid, multifidus and erector spinae muscles during upper limb flexion and abduction in standing position. Relative differences in the onset times between each muscle and the prime mover were calculated. Results:During upper limb flexion, the right multifidus muscle, bilateral erector spinae were activated in advance of the agonist muscle (anterior deltoid), while the left multifidus muscle was delayed relative to the agonist muscle in both groups. The onset time of the right erector spinae was significantly delayed in NLBP group than in the control group (t = -2.393, P = 0.019). During upper limb abduction, bilateral multifidus muscle and bilateral erector spinae were activated in advance of the agonist muscle (middle deltoid) in the control group. Additionally, in NLBP group, the left erector spinae was activated in advance of the agonist muscle, bilateral multifidus and right erector spinae were delayed relative to the agonist muscle. There was no significant difference in the relative onset time between both groups (t < 1.393, P > 0.05). Conclusion:During upper limb flexion and abduction, the trunk muscles of the lower back are activated in advance for healthy individuals, while individuals with NLBP have a possibly delayed activation of trunk muscles.

BACKGROUNDApproximately 15-20% cases of systemic lupus erythematosus (SLE) are diagnosed in children. There have been a few studies reporting the epidemiological data of pediatric-onset SLE (cSLE) in China, neither comparing the differences between cSLE and adult-onset SLE (aSLE). The aim of this study was to describe the impact of age of onset on clinical features and survival in cSLE patients in China based on the Chinese SLE Treatment and Research group (CSTAR) database.

METHODSWe made a prospective study of 225 cSLE patients (aged Results: The mean age of cSLE patients was 12.16 ± 2.92 years, with 187 (83.1%) females. Fever (P < 0.001) as well as mucocutaneous (P < 0.001) and renal (P = 0.006) disorders were found to be significantly more frequent in cSLE patients as initial symptoms, while muscle and joint lesions were significantly less common compared to aSLE subjects (P < 0.001). The cSLE patients were found to present more frequently with malar rash (P = 0.001; odds ratio [OR], 0.624; 95% confidence interval [CI], 0.470-0.829) but less frequently with arthritis (P < 0.001; OR, 2.013; 95% CI, 1.512-2.679) and serositis (P = 0.030; OR, 1.629; 95% CI, 1.053-2.520). There was no significant difference in SLE disease activity index scores between cSLE and aSLE groups (P = 0.478). Cox regression indicated that childhood onset was the risk factor for organ damage in lupus patients (hazard ratio 0.335 [0.170-0.658], P = 0.001). The survival curves between the cSLE and aSLE groups had no significant difference as determined by the log-rank test (0.557, P = 0.455).

CONCLUSIONScSLE in China has different clinical features and more inflammation than aSLE patients. Damage may be less in children and there is no difference in 5- year survival between cSLE and aSLE groups.

Gastrodia elata has been used in China for more than 2 000 years and it is a kind of valuable traditional Chinese medicine. The originrecords of G. elata were Mount Tai of Shandong and and Mount Song of Henan, which began in Wupu Bencao of Wei Jin Dynasties, and Tai'an and its surrounding areas had been the Do-di herbs production areas. But from the beginning of the Republic of China, G. elata origin has undergone major changes, Do-di herbs production areas moved westward to the southwest.In this paper,through literature research and field visits, we studied the formation and changes of Do-di herbs production areas of G. elata. The cultivation history and current main producing area of G. elata was also introduced. On this basis, we profoundly summarized the reasons of Do-di herbs production areas formation and changes from the nature, society, transportation, humanities and germplasm resources.Combining the ancient herbal medicine and the characteristics of modern producing areas, the planting strength of G. elata could be strengthened in the hope of providing reference for the quality evaluation and cultivation of G. elata.

Due to the particularity of ginseng cultivation, the soil fertility of cultivated ginseng is seriously depleted, so that the cultivated ginseng land can not be reused in the short term, and the land area available for cultivating ginseng becomes less and less with the growth of ginseng cultivation time. Therefore, in order to effectively manage ginseng cultivation, and achieve the sustainable use of ginseng land, it is necessary to obtain accurate information on the distribution of ginseng planting space. In this study, the object-oriented classification method based on rule set was used to extract ginseng planting area based on the ZY-3 satellite data in Fusong county, Jilin province. Firstly, multi-scale segmentation of ZY-3 remote sensing image in the study area was made, and the optimal segmentation scale was determined on the basis of multi-scale segmentation results. Secondly, a spectral curve according to the different feature type samples was generated. The similarities and differences between ginseng plot and other types of surface features were analyzed, and a rule set based on the results of spectral analysis was established to achieve the final extraction. The results show that the object-oriented classification method based on rule set can effectively extract the ginseng planting plots in the study area, and solve the problem that the extraction result is broken compared with the traditional pixel-based classification method.

Objective To improve vibration resistance of conventional blood transportation kits and mitigate hemolysis during transportation.Methods The structure of a blood transportation kit was modified.We installed a suspension brac-kets within the kit,added buffer material between the brackets,and tested the vibration-suppressing effect compared with the conventional blood transportation kit.Results Rubber and plastic materials between brackets were added,and double membrane suspension brackets were installed.After 4 and 6 min of vibration,free hemoglobin(FHb)[(1559.7 ±1038.5) and(1886.2 ±1023.8)mg/L],lactic dehydrogenase levels[(135.3 ±67.7)and(195.7 ±123.6)U/L]and hemolysis rate[(0.35 ±0.34)%and(0.42 ±0.38)%]in the conventional transportation kit were significantly higher than in the vibration-suppressing kit.K+did not change significantly,and was comparable in both groups at each time point.After 4 and 6 min of vibration, FHb in the conventional transportation kit exceeded the standard.However, after 12 min of vibration,FHb[(560.1 ±342.3)mg/L]in the vibration-suppressing kit were within the standard range.No bacterial growth was detected in either group.Conclusion The vibration-suppressing kit under research shows a better 1986vibration-suppressing effect,which could improve blood support capability in case of emergency.
