Abstract
Cynanchumpingtaoi S.Jin Zeng, G.D.Tang & Miao Liao, sp. nov. (Apocynaceae) from Yunnan Province, China, is described and illustrated based on morphological and molecular evidence. Its deeply cordate to reniform leaves and campanulate, large flowers show that it is a member of former Raphistemma Wall., which has been included in Cynanchum L.. It is different from all former Raphistemma species by the broadly ovate corolla lobes, purple-red corolla and connivent corona tip slightly exceeding the corolla throat. Meanwhile, Cynanchumlonghushanense G.D.Tang & Miao Liao, nom. nov. is proposed as replacement name for Raphistemmabrevipedunculatum Y.Wan, which was considered a synonym of Cynanchumhooperianum (Blume) Liede & Khanum but is here reinstated as a distinct species because of significant morphological differences.

Abstract
Objective: To study the effect of samarium trioxide (Sm(2)O(3)) particles on rat lung tissue and compare it with the same dose of silica (SiO(2)) particles, in order to find the reference index for early screening of pneumoconiosis. Methods: In October 2018, 72 SPF healthy male rats were randomly divided into control group, SiO(2) group and Sm(2)O(3) group. The lungs of rats in each group were perfused with 2.0 ml/kg normal saline and 280 mg/kg SiO(2) and Sm(2)O(3) particle suspension by one-time non exposed tracheal perfusion. The lungs of rats were stained with hematoxylin eosin (HE) staining, and the pathological changes of lung tissues were observed. The concentrations of SNAIL homologue 1 (SNAI1) , SNAIL homologue 2 (SNAI2) , and heat shock protein-27 (HSP-27) in rat serum were detected by enzyme-linked immunosorbent assay. 0.5 g of lung tissue from rats in Sm(2)O(3) group and control group exposed to dust for 56 days was screened for long-chain noncoding RNA (lncRNA) and circular RNA (circRNA) . Results: After 7 days of dust exposure, the alveoli in SiO(2) group and Sm(2)O(3) group were disordered, and lymphoid tissue aggregation and proliferation were observed around the bronchial wall. At 14 days, a large number of lymphocytes infiltrated in SiO(2) group, and a small number of macrophages containing Sm(2)O(3) and fibrotic nodules scattered in Sm(2)O(3) group. At 28 days, a small amount of lymphocyte infiltration appeared in SiO(2) group, and fibrotic nodules were seen in some areas of Sm(2)O(3) group. At 56 days, there was a small amount of fibroblast proliferation in SiO(2) group, and a large number of fibrotic nodules containing gray black matter were seen in Sm(2)O(3) group. There was no significant difference in lung organ coefficient among groups at different dust exposure time (P>0.05) . After 14 days of dust exposure, the contents of SNAI1 and SNAI2 in serum of rats in SiO(2) group were lower than those in control group, the content of SNAI2 in serum of Sm(2)O(3) group was lower than that in control group, and the contents of SNAI1 and SNAI2 in serum of Sm(2)O(3) group were higher than those in SiO(2) group (P<0.05) . The content of HSP-27 in SiO(2) group was lower than that in control group (P<0.05) . After 56 days of dust exposure, the content of HSP-27 in Sm(2)O(3) group was lower than that in control group (P<0.05) . At 56 days, lncRNA in Sm(2)O(3) group was up-regulated by 148 and down regulated by 725, circRNA was up-regulated by 16 and down regulated by 153. Conclusion: Sm(2)O(3) can cause lung injury in rats, and the change of SNAI2 content can be detected in the early stage, which can be used as a reference index for early screening of pneumoconiosis. There are differences in the expression of lncRNA and circRNA after 56 days of dust exposure in rats, which may be related to the pathogenesis of pneumoconiosis.

Abstract
OBJECTIVE To investigate the current distribution of ticks and predict the suitable habitats of ticks in the Yangtze River Delta urban agglomeration in 2017, so as to provide insights into tick control and management of tick-borne diseases in these areas. METHODS All publications pertaining to tick and pathogen distribution in the Yangtze River Delta urban agglomeration were retrieved, and the geographical location of tick distribution was extracted. The effects of 19 climatic factors on the distribution of ticks were examined using the jackknife method, including the mean temperature of the wettest quarter, precipitation of the coldest quarter, mean temperature of the driest quarter, maximum temperature of the warmest month, precipitation of the driest month, minimal temperature of the coldest month, annual precipitation, mean daily temperature range, precipitation seasonality, annual temperature range, temperature seasonality, annual mean temperature, mean temperature of the warmest quarter, precipitation of the wettest quarter, isothermality, mean temperature of the coldest quarter, precipitation of the wettest month, precipitation of the driest quarter and precipitation of the warmest quarter. The distribution of ticks was analyzed in 2020 using the maximum entropy (MaxEnt) model, and the potential suitable habitats of ticks were predicted in 2070 using the MaxEnt model based on climatic data. RESULTS A total of 380 Chinese and English literatures were retrieved, and 148 tick distribution sites were extracted, with 135 sites included in the subsequent analysis. There were 7 genera (Haemaphysalis, Rhipicephalus, Ixodes, Dermacentor, Boophilus, Hyalomma and Amblyomma) and 27 species of ticks detected in the Yangtze River Delta urban agglomeration. The climatic factors affecting the distribution of ticks in the Yangtze River Delta urban agglomeration mainly included the mean temperature of the wettest quarter and the precipitation of the coldest quarter, with 26.1% and 23.6% contributions to tick distributions. The high-, medium- and low-suitable habitats of ticks were 20 337.08, 40 017.38 km2 and 74 931.43 km2 in the Yangtze River Delta urban agglomeration in 2020, respectively. The climate changes led to south expansion of the suitable habitats of ticks in the Yangtze River Delta urban agglomeration in 2070, and the total areas of suitable habitats of ticks was predicted to increase by 18 100 km2. In addition, the high-, medium- and low-suitable habitats of ticks were predicted to increase to 24 317.84, 45 283.02 km2 and 83 766.38 km2 in the Yangtze River Delta urban agglomeration in 2070, respectively. CONCLUSIONS Multiple tick species are widespread in the Yangtze River Delta urban agglomeration, and the future climate changes may lead to expansion of tick distribution in these areas.

Abstract
The effects of dietary β-hydroxy-β-methylbutyrate (HMB) supplementation during gestation on reproductive performance of sows and the mRNA expression of myogenic markers in skeletal muscle of neonatal pigs were determined. At day 35 of gestation, a total of 20 sows (Landrace × Yorkshire, at third parity) were randomly assigned to two groups, with each group receiving either a basal diet or the same diet supplemented with 4 g/day β-hydroxy-β-methylbutyrate calcium (HMB-Ca) until parturition. At parturition, the total and live litter size were not markedly different between treatments, however, the sows fed HMB diet had a decreased rate of stillborn piglets compared with the sows fed the control (CON) diets (p < 0.05). In addition, piglets from the sows fed HMB diet tended to have an increased birth weight (p = 0.08), and a reduced rate of low birth weight piglets (p = 0.05) compared with piglets from the CON sows. Nevertheless, lower feed intake during lactation was observed in the sows fed the HMB diet compared with those on the CON diet (p < 0.01). The relative weights of the longissimus dorsi (LD) and semitendinosus (ST) muscle were higher (p < 0.05) in neonatal pigs from the HMB than the CON sows. Furthermore, maternal HMB treatment increased the mRNA levels of the myogenic genes, including muscle regulatory factor-4 (MRF4, p < 0.05), myogenic differentiation factor (MyoD) and insulin-like growth factor-1 (IGF-1, p < 0.01). In conclusion, dietary HMB supplementation to sows at 4 g/day from day 35 of gestation to term significantly improves pregnancy outcomes and increases the expression of myogenic genes in skeletal muscle of neonatal piglets, but reduces feed intake of sows during lactation.

Abstract
BALB/C mice (H-2d) receiving allogeneic C57 mice (H-2b) spleen cells via the portal vein (PV), followed by administration of cyclophosphamide (CY), abrogated the capability of rejecting allogeneic EL-4G- tumor cells (C57 origin). BALB/C mice received this combined treatment and BALB/C mice untreated or treated with either PV presensitization or CY injection were all exposed to 7.5 Gy total body irradiation, which was confirmed to be a lethal dose for BALB/C mice, then given intravenously 2 x 10(7) fetal liver cells from C57 mice (FLC57). The results indicated that the survival times of grafted BALB/C mice combined treatment were longer than those of untreated or either PV or CY treated, (PV + CY + 7.5Gy + FLC 57: MST = 99.5 +/- 12.6 day), v(N + 7.5GY + FLC57: MST = 36.5 +/- 9.8 day; PV + 7.5Gy + FLC57: MST = 12.2 +/- 0.2 day; CY + 7.5Gy + FLC57: MST = 27.6 +/- 5.5 day). The difference was statistically significant. The spleen cells from the grafted mice were assessed by indirect immunofluorescence with anti-C57 serum. The spleen cells from BALB/C mice with survival time over 100 days after grafting of FLC57 in combined treatment group were about 70-80 percentage of C57 positive cells.

Abstract
We report here the results of a phase I clinical trial using counterflow centrifugal elutriation (CCE) for the removal of donor T lymphocytes before allogeneic bone marrow transplantation (BMT). Thirty-eight patients received lymphocyte-depleted allografts from HLA-identical, MLR-nonreactive sibling donors. The patients entered onto the study were either at high risk on the basis of age (median, 39 years) or disease status (acute leukemia in early relapse [ER], chronic myelogenous leukemia [CML] in accelerated phase [AP], or therapy resistant [RES] lymphoma). All patients received a standard lymphocyte dose of 1 x 10(6) morphologic lymphocytes per kilogram ideal body weight (BW) and were maintained on cyclosporine A (CsA) for 170 days after BMT. Prompt engraftment occurred in 37 of 38 patients with a median time to absolute neutrophil count (ANC) greater than 500/microL of 18 days. Although acute graft-v-host disease (GVHD; clinical stage I or greater) was observed in 45%, it was limited to the skin in all but five patients. Survival was related to disease status at the time of BMT. Among patients with acute leukemia in first or second remission, CML in chronic phase (CP) or lymphoma in partial remission (PR), 64% are currently alive, in contrast to 31% of patients with acute leukemia in third remission or early relapse, CML in second CP or AP, or RES lymphoma. Median follow-up for all patients was 351 days (range, 105 to 711 days). We conclude that this procedure is safe and warrants further evaluation in a randomized efficacy trial.
