Abstract
Objective: To evaluate the efficacy of the Hodgkin lymphoma (HL)-2013 regimen in the treatment of children with HL, and to investigate the prognostic factors of childhood HL. Methods: Clinical data of 145 children (aged ≤18 years) with newly diagnosed HL, treated with HL-2013 regimen in 8 tertiary referral centers for childhood cancer from August 2011 to April 2021 were analyzed retrospectively. All the diagnosis were confirmed by histopathological morphology and immunohistochemical examination. The clinical characteristics and treatment outcomes were summarized, and the patients were divided into different groups according to clinical characteristics. Kaplan-Meier method was used for survival analysis, and the comparison of survival rates between groups was performed with Log-rank test. Results: Of the 145 cases, there were 115 males and 30 females, the age at diagnosis was 7.9 (5.8, 10.6) years. Cervical lymph node enlargement (114 cases, 78.6%) was the common symptom of the disease, and 57 patients (39.3%) were accompanied by large masses. The most common pathological classification was mixed cell type (93 cases, 64.1%). According to the Ann Arbor staging system, there were 9 cases of stage Ⅰ, 62 cases of stage Ⅱ, 45 cases of stage Ⅲ, 29 cases of stage Ⅳ. According to the risk stratification: there were 14 cases of low-risk group, 76 cases of medium-risk group and 55 cases of high-risk group. Of all patients, 68 cases (46.9%) achieved an early complete remission (CR) after 2 courses of chemotherapy, and the CR rate was 93.8% (136/145) after first-line treatment. Disease recurrence or progression occurred in 22 cases (15.2%). Of all patients, 125 cases survived, 6 cases died and 14 cases were lost to follow-up. Among the survived cases, 123 cases were continuously at CR state,and the follow-up time was 55 (40, 76) months. The 5-year overall survival (OS) and event free survival (EFS) rates were (95.3±1.9)% and (84.2±3.0)% for the entire group, respectively. 5-year OS and EFS rates for patients with stage Ⅲ-Ⅳ were both lower than those for patients with stage Ⅰ-Ⅱ (χ2=6.28 and 7.58, both P<0.05), the 5-year OS and EFS rates for patients in high-risk group were both lower than those for patients in low-risk and medium-risk group (χ2=10.93, 7.79, both P<0.05). The 5-year OS rates for the patient with early CR and without early CR were 100.0% and (90.9±3.6)% (χ2=5.77, P=0.016). EFS rates for the patient with early CR (68 cases) and without early CR (77 cases) were (93.8±3.0)% and (75.8±5.0)% (χ2=8.78, P=0.003). Conclusions: HL-2013 regimen is significantly effective in the treatment of pediatric HL. However, the patients in high-risk group and those without early CR are prone to disease recurrence or progression. Stage Ⅲ-Ⅳ and without early CR were associated with worse prognosis.

Abstract
The ongoing pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is currently affecting millions of lives worldwide. Large retrospective studies indicate that an elevated level of inflammatory cytokines and pro-inflammatory factors are associated with both increased disease severity and mortality. Here, using multidimensional epigenetic, transcriptional, in vitro, and in vivo analyses, we report that topoisomerase 1 (TOP1) inhibition suppresses lethal inflammation induced by SARS-CoV-2. Therapeutic treatment with two doses of topotecan (TPT), an FDA-approved TOP1 inhibitor, suppresses infection-induced inflammation in hamsters. TPT treatment as late as 4 days post-infection reduces morbidity and rescues mortality in a transgenic mouse model. These results support the potential of TOP1 inhibition as an effective host-directed therapy against severe SARS-CoV-2 infection. TPT and its derivatives are inexpensive clinical-grade inhibitors available in most countries. Clinical trials are needed to evaluate the efficacy of repurposing TOP1 inhibitors for severe coronavirus disease 2019 (COVID-19) in humans.

Abstract
Objective: To observe content of cytokine in human stromal vascular fraction gel (SVF-GEL) and effect of SVF-GEL on biological behaviors of epidermal and dermal cells in vitro and clinical efficacy of SVF-GEL. Methods: (1) SVF-GEL was prepared using liposuction aspirates harvested from females who received abdomen liposuction in author's unit. SVF-GEL (1 mL) and high-glucose Dulbecco's modified eagle medium (DMEM, 1 mL) were respectively cultured for 24 h with high-glucose DMEM containing 10% fetal calf serum, 10 g/L penicillin, and 10 g/L streptomycin, denoted as SVF-GEL group and negative control group, with 6 samples in each group. Content of epidermal growth factor (EGF) and vascular endothelial growth factor (VEGF) in the supernatant was determined by enzyme-linked immunosorbent assay. (2) A number of 5×10(5) human skin fibroblasts (HSF) and HaCaT cells in logarithmic phase were inoculated and cultured in Transwell chambers for 12 h. All Transwell chambers containing cells were divided into SVF-GEL group (0.5 mL SVF-GEL was added for co-culture) and control group (0.5 mL high-glucose DMEM was added for co-culture), with 9 samples in each group for HSF and HaCaT cells. Scratch assay was performed after culture for 24 h, and residual scratch width was observed at post scratch hour (PSH) 0 (immediately), 24, and 48. Cell migration distance was measured at PSH 24 and 48. After culture for 24, 48, and 72 h, the number of living cell was counted using cell counter. (3) From June 2018 to June 2019, SVF-GEL was applied clinically to treat 15 patients with depressed scars on face, including 2 males and 13 females, aged 19 to 42 years. Survival condition of SVF-GEL and whether complications or not were observed 6 months after surgery. Before surgery and 6 months after surgery, depressed degree, color, and pliability of scar were compared. Vancouver Scar Scale (VSS) was employed to access color, vascularity, and pliability before surgery and 6 months after surgery, and total score was calculated. The number of patients with complete satisfaction or satisfaction was counted six months after surgery. Data were processed with analysis of variance of factorial design, paired samples t test, and Wilcoxon rank sum test. Results: (1) The content of EGF in SVF-GEL group and negative control group was (316.6±12.8) and (3.4±0.6) pg/mL, and the content of VEGF in SVF-GEL group and negative control group was (568.67±12.19) and (4.93±0.16) pg/mL, with statistically significant differences between the two groups (t=48.777, 92.485, P<0.01). (2) Residual scratch widths of HSF and HaCaT in SVF-GEL group and control group were decreased gradually along with time elapse, in which those in SVF-GEL group at PSH 24 and 48 were less than those in control group. At PSH 24 and 48, cell migration distances of HSF and HaCaT in SVF-GEL group were more than those in control group (t(HSF)=-20.304, -43.516, t(HaCaT)=-15.060, -8.684, P<0.01). After culture for 24, 48, and 72 h, the number of living cell of HSF and HaCaT in SVF-GEL group was significantly more than that in control group (t(HSF)=-3.374, -6.809, -18.036, t(HaCaT)=-4.793, -6.028, -8.141, P<0.05 or P<0.01). (3) Six months after surgery, SVF-GEL grafted into patients survived well without complications, and depressed degree of scar ameliorated obviously with lightened pigmentation and softer texture as compared with before surgery. Compared with those before surgery, VSS scores of color, vascularity, and pliability, and total score of 15 patients with depressed scars on face were obviously decreased 6 months after surgery (Z=-2.06, -2.07, -2.07, t=-15.811, P<0.05 or P<0.01). One patient was satisfied with the clinical outcome, and the rest 14 patients were completely satisfied with the clinical outcomes. Conclusions: SVF-GEL contains cytokines EGF and VEGF, which can enhance cell migration ability and proliferation ability of HSF and HaCaT cells and have obvious effects on depressed scars for clinical application.

Abstract
AIMS The objectives of this study were to estimate the prevalence of digital dermatitis (DD) in Victoria, Australia, and to investigate which organisms are consistent with typical DD lesions. The prevalence and causative pathogens of DD are not clear yet in Australia and this paper is one of the first to explore these questions in this country. METHODS Examination and sampling of limbs was undertaken at three knackeries in Victoria, Australia. Limbs were classified as normal (N), active DD-lesion (A), dried or chronic DD-lesion (D) or suspected case of DD (S). A total of 823 cows were examined. Six skin biopsies were taken at each knackery, from which DNA was extracted for diversity profiling. Histochemical staining of samples was performed on eight of the skin biopsies. RESULTS DD was detected in 29.8% of all cows. The prevalence of DD was significantly higher in dairy cows (32.2%) than in beef cows (10.8%). The differential abundance of Treponema-species was significantly increased in dried lesions, compared with the normal skin biopsies. Actinobacteria, Proteobacteria, Firmicutes and Tenericutes were found to be significantly different in abundance in the DD lesions compared with normal skin biopsies. Silver staining of samples showed only mild inflammation and in two samples organisms with morphology consistent with Spirochaetes were detected. CONCLUSIONS The calculated prevalence indicates that DD is present in Victoria, Australia. The results of diversity profiling showed that the presence of Treponema-species was significantly different between the samples of DD lesions and normal skin.

Abstract
BACKGROUND AND PURPOSE Anterior circulation large-vessel occlusion stroke, one of the most devastating stroke subtypes, is associated with substantial economic burden. We aimed to identify predictors of increased acute care hospitalization costs associated with anterior circulation large-vessel occlusion stroke. MATERIALS AND METHODS Comprehensive cost-tracking software was used to calculate acute care hospitalization costs for patients with anterior circulation large-vessel occlusion stroke admitted July 2012 to October 2014. Patient demographics and stroke characteristics were analyzed, including final infarct volume on follow-up neuroimaging. Predictors of hospitalization costs were determined using multivariable linear regression including subgroup cost analyses by treatment technique (endovascular, IV tPA-only, and no reperfusion therapy) and sensitivity analyses incorporating patients initially excluded due to early withdrawal of care. RESULTS Three hundred forty-one patients (median age, 69 years; interquartile range, 57-80 years; median NIHSS score, 16; interquartile range, 13-21) were included in our primary analysis. Final infarct volume, parenchymal hematoma, baseline NIHSS score, ipsilateral carotid stenosis, age, and obstructive sleep apnea were significant predictors of acute care hospitalization costs. Final infarct volume alone accounted for 20.87% of the total cost variance. Additionally, final infarct volume was consistently the strongest predictor of increased cost in primary, subgroup, and sensitivity analyses. CONCLUSIONS Final infarct volume was the strongest predictor of increased hospitalization costs in anterior circulation large-vessel occlusion stroke. Acute stroke therapies that reduce final infarct volume may not only improve clinical outcomes but may also prove cost-effective.

Abstract
OBJECTIVE To compare and analyze the clinical effects of arthroscopic therapy and drug therapy in treating anterior cruciate ligament (ACL) rupture with secondary osteoarthritis (OA). PATIENTS AND METHODS A total of 68 patients that were diagnosed as ACL rupture with secondary OA in our hospital from February 2014 to February 2015 were enrolled in our study. All of the patients were randomly divided into control group (n = 30) and observation group (n = 38) according to the order of admission. The patients in the control group were given analgesic, anti-inflammatory drugs + functional rehabilitation training whereas the patients in the observation group were given ACL reconstruction + OA debridement and functional rehabilitation training under arthroscopy. RESULTS The success rate of the observation group was 92.1%. After 3-month follow-up, the clinical total effective rate of the observation group was significantly higher than that of the control group, the prevalence of complications in the observation group was significantly lower than in the control group, and differences were statistically significant (p < 0.05). Lysholm scale scoring of observation group was significantly higher than of the control group, modified McGill pain scale score was significantly lower than that of the control group, and differences were statistically significant (p < 0.05). Quadriceps muscle peak torque, average power, and the optimal single work at 60°/s, 120°/s, and 180°/s were significantly higher than those of the control group, and differences were statistically significant (p < 0.05). CONCLUSIONS Arthroscopic operative therapy was safe and effective for the treatment of ACL with secondary OA. Compared with drug therapy, it can significantly improve the movement function of the knee joint, so it was worthy of clinical application.

Abstract
Twelve dimeric peptidomimetics 1 were prepared via a divergent-convergent strategy. These peptidomimetics incorporated the same amino acids as i +1 and i + 2 residues in key beta-turns of the neurotrophin NT-3. Cytosensor microphysiometry was used to gauge the effects of the dimers 1 on cells that overexpress the NT-3 receptor, TrkC. Increases in extracellular acidification rates were observed for some monomers 3, but the active dimers gave greater effects.

Abstract
A library of guanidine-based compounds was produced to mimic the lead compound 1, which is a substance known to have intensely sweet-taste characteristics. Libraries of guanidinocarboxylic acids were therefore prepared via two synthetic methods. The solid-phase method involving trapping of solution-phase carbodiimides by supported amines was used to produce N,N'-dialkyl derivatives (Scheme 1). The second solid-phase method, featuring supported carbodiimides and solution-phase amines (Scheme 2), was devised to prepare N,N'-disubstituted and N,N',N'-trisubstituted guanidinocarboxylic acids. A small collection of guanadinoacetic acid dimers and trimers was also prepared, but this time via a solution-phase coupling of carbodiimides to a polyamine linker.

Abstract
The Giant Panda is an endangered species that would benefit from biotechnological assistance in reproduction. However, because there are only a few of these animals left in the world, scientists hesitate to use them for research procedures. We were fortunate to obtain ovaries from a Giant Panda that died of hepatic cirrhosis during the nonbreeding season. Oocytes were harvested within 4 h of death by dissecting the ovarian cortex in physiological saline and collecting the cumulus-oocyte complexes from the fluid, and then were classified into large (> 125 microns) and small (100 to 124 microns) follicular oocytes and placed in TCM199 supplemented with FSH (10 micrograms/mL) and LH (20 micrograms/mL). After culture for 22 h at 37 degrees C in air with 5% CO2, response was evaluated by growth of oocytes and presence of the first polar body. Of the 26 large follicular oocytes that were harvested, 12 were considered suitable for IVM, and 14 were degenerated, had a broken zona pellucida or had lost some cytoplasm. Of the 12 cultured oocytes, all grew to a mean diameter of 141.1(SD = +/- 6.7, n = 12), and 4 released the first polar body. None of the small follicular oocytes showed growth or other signs of maturation. We conclude from our preliminary results that it is possible to obtain functional Giant Panda oocytes from ovaries obtained post mortem during the nonbreeding season.

Abstract
1-(2'-Deoxy-beta-d-ribofuranosyl)-3-nitropyrrole phosphate was incorporated into a DNA decamer and analyzed via matrix-assisted laser desorption ionization mass spectrometry (MALDI-MS). The extent and composition of the various fragment peaks were compared with those in the MALDI-MS spectrum of dT4AT5. The nitropyrrole-containing oligomer proved to be more robust. Two different DNA template assays were then used to attempt to identify DNA replicating enzymes that would incorporate the corresponding triphosphate, i.e. 1-(2'-deoxy-beta-d-ribofuranosyl)-3-nitropyrrole triphosphate (dXTP). It was shown that dXTP was not incorporated by some enzymes and it inhibited others. However, DNA polymerase I Klenow fragment and avian myeloblastosis virus reverse transcriptase incorporated dXTP in place of dATP and then replicated the template overhang in the usual way. The potential of dXTP as a surrogate for dATP in DNA sequencing with MALDI-MS analysis is discussed.

Abstract
The catalytic subunit of rabbit skeletal muscle protein phosphatase-1 was expressed in Escherichia coli. Expression of phosphatase-1 in the pET3a vector, which is based on the use of the T7 promoter, resulted in the expression of the enzyme as an insoluble aggregate. The insoluble enzyme could be renatured by high dilutions of the urea-solubilized protein in buffers containing dithiothreitol, Mn2+, and high NaCl concentrations. However, under all conditions tested, only partial (less than 5%) renaturation was achieved. A second attempt was made using a vector with the trp-lac hybrid promoter. In this case it was possible to express the enzyme as a soluble protein at levels of 3-4% of the soluble E. coli protein. The recombinant enzyme was purified by DEAE-Sepharose and heparin-Sepharose chromatography. Approximately 20 mg of purified enzyme was reproducibly obtained from the cells derived from 2 liters of culture. The purified enzyme had a specific activity toward phosphorylase alpha comparable to that reported for the authentic protein and had an Mr of 37,000 by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The recombinant enzyme displayed similar sensitivities to inhibition by inhibitor-2, okadaic acid, and microcystin-LR as for the protein isolated from rabbit muscle. At all stages of purification the recombinant phosphatase behaved as an essentially inactive enzyme that required the presence of microM Mn2+ for full expression of its activity.

Abstract
A preliminary report on in vitro sperm capacitation and egg-penetration of giant panda is briefly presented. The panda spermatozoon consists of head, neck and tail, just like the spermatozoa of other animals. Before capacitation sperm heads clustered together and dispersed after capacitation. They were then able to swim straight forward. During the time of in vitro capacitation the plasma membrane of the sperm head was first expanded to various degrees, then disintegrated, and finally became detached. The electro-dense material in the acrosome appeared in small clumps with high density. Extensive vesiculation occurred between the bi-layered acrosome membranes and thus led to disintegration. Vesiculation in panda sperm differs from that reported in hamsters. When the capacitated panda spermatozoa came into contact with the hamster eggs, the region between the acrosome collar and postacrosome cap first fused with the egg membrane followed by the penetration of the nucleus into the cortex of the egg. Some of the penetrating sperm nuclei became decondensed and some did not. The success of in vitro sperm capacitation and egg-penetration of giant panda is of great significance, suggesting that it is possible to carry out in vitro fertilization and embryo transplantation in this endangered species.
