Abstract
Prunus is an economically important genus widely distributed in the temperate Northern Hemisphere. Previous studies on the genus using a variety of loci yielded conflicting phylogenetic hypotheses. Here, we generated nuclear reduced representation sequencing data and plastid genomes for 36 Prunus individuals and two outgroups. Both nuclear and plastome data recovered a well-resolved phylogeny. The species were divided into three main clades corresponding to their inflorescence types, - the racemose group, the solitary-flower group and the corymbose group - with the latter two sister to one another. Prunus was inferred to have diversified initially in the Late Cretaceous around 67.32 million years ago. The diversification of the three major clades began between the Paleocene and Miocene, suggesting that paleoclimatic events were an important driving force for Prunus diversification. Ancestral state reconstructions revealed that the most recent common ancestor of Prunus had racemose inflorescences, and the solitary-flower and corymb inflorescence types were derived by reduction of flower number and suppression of the rachis, respectively. We also tested the hybrid origin hypothesis of the racemose group proposed in previous studies. Prunus has undergone extensive hybridization events, although it is difficult to identify conclusively specific instances of hybridization when using SNP data, especially deep in the phylogeny. Our study provides well-resolved nuclear and plastid phylogenies of Prunus, reveals substantial cytonuclear discord at shallow scales, and sheds new light on inflorescence evolution in this economically important lineage.

Abstract
Based on the Global Burden of Disease study 2019, the standardized mortality rate and disability-adjusted life years (DALYs) rate of children under 5 years old were selected as evaluation indicators to compare and analyze the current situation and differences of disease burden of children under 5 years old between China and other regions from 1990 to 2019. The change trend and difference of disease burden of children under 5 years old in China were analyzed by sexes. From 1990 to 2019, the all-cause standardized mortality rate of children under 5 years old in China decreased from 1 153.81/100 000 to 160.39/100 000, and the all-cause standardized DALY rate decreased from 104 426.40/100 000 to 16 479.01/100 000. In 2019, neonatal preterm birth, congenital heart anomalies and lower respiratory infections ranked the top three disease burden of children under 5 years old in China. Except that the disease burden of neonatal preterm birth was lower than that in North America, they were much higher than that in Western Europe and North America in the same period. The burden of unintentional injury diseases, including pulmonary aspiration and foreign body in airway and drowning, was higher than that in Western Europe and North America. The standardized mortality and DALY rate of the top ten diseases and injuries in boys and girls under 5 years old in China showed a downward trend (P<0.05), and most of them were higher in boys than girls (P<0.05). From 1990 to 2019, the disease burden of children under 5 years old in China decreased significantly. However, compared other regions, it is still necessary to strengthen the prevention and control of neonatal premature birth, birth defects and unintentional injuries, and take different sex-specific interventions to improve the overall health of children.

Abstract
Objective: To study the effects of vibration on the expression of mitochondrial fusion and fission genes and ultrastructure of skeletal muscle in rabbits. Methods: Thirty-two 3.5-month-old New Zealand rabbits were randomly divided into low-intensity group, medium-intensity group, high-intensity group and control group, with 8 rabbits in each group. The rabbits in the experimental group were subjected to hind limb vibration load test for 45 days. The vibration intensity of the high intensity group was 12.26 m/s(2), the medium intensity group was 6.13 m/s(2), and the low intensity group was 3.02 m/s(2) according to the effective value of weighted acceleration[a(hw (4))] for 4 hours of equal energy frequency. The control group was exposed to noise only in the same experimental environment as the medium-intensity group. The noise levels of each group were measured during the vibration load experiment. After the test, the mRNA expression of mitochondrial fusion gene (Mfn1/Mfn2) and fission gene (Fis1, Drp1) by RT-PCR in the skeletal muscles were measured and the ultrastructure of the skeletal muscles were observed in high intensity group. Results: The mRNA expression of mitochondrial in the skeletal muscle tissues of control group, low intensity group, medium intensity group and high intensity group were Mfn1: 3.25±1.36, 3.85±1.90, 4.53±2.31 and 11.63±7.68; Mfn2: 0.68±0.25, 1.02±0.40, 0.94±0.33 and 1.40±0.45; Fis1: 1.05±0.62, 1.15±0.59, 1.53±1.06 and 2.46±1.51 and Drp1: 3.72±1.76, 2.91±1.63, 3.27±2.01 and 4.21±2.46, respectively. Compared with the control group, the expressions of Mfn1 mRNA, Mfn2 mRNA and Fis1 mRNA in the high-intensity group increased significantly (P<0.05) , and the expressions of Mfn2 mRNA in the medium-intensity group and the low-intensity group increased significantly (P<0.05) . Compared with the control group, the ultrastructure of skeletal muscle of high intensity group showed mitochondrial focal accumulation, cristae membrane damage, vacuole-like changes; Z-line irregularity of muscle fibers, and deficiency of sarcomere. Conclusion: Vibration must be lead to the abnormal mitochondrial morphology and structure and the disorder of energy metabolism due to the expression imbalance of mitochondrial fusion and fission genes in skeletal muscles of rabbits, which may be an important target of vibration-induced skeletal muscle injury.

Abstract
Objective: To investigate the recurrence and influencing factors of diabetic foot ulcer in patients with type 2 diabetes mellitus. Methods: Totally 185 type 2 diabetes patients with new-onset of diabetic foot ulcers admitted to Fuyang People's Hospital of Anhui Province from January 2011 to December 2015 were enrolled in this study, including 120 males and 65 females, aged 40-79 years. All the patients were followed up for 3 years, and their clinical data were retrospectively analyzed by the case-control study. The Kaplan-Meier cumulative recurrence curve was drawn according to the 3-year cumulative recurrence rate of diabetic foot ulcers. The time to visit, toe involvement, and amputation of involved toes in patients with recurrent diabetic foot ulcer were counted at the initial onset and the recurrence of the ulcers, respectively, and the data were statistically analyzed with t test and chi-square test. According to the recurrence of diabetic foot ulcers, the patients were divided into foot ulcer recurrence group and foot ulcer non-recurrence group. The gender, age, course of diabetes mellitus, length of hospital stay, visit time, body mass index, glycosylated hemoglobin HbA1c, total bilirubin, albumin, creatinine, cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL), triglycerides, hemoglobin, white blood cell count, toe involvement, toe amputation, ankle-brachial index, diabetic retinopathy (DR), diabetic peripheral neuropathy (DPN), diabetic nephropathy (DN), history of hypertension, cardio-cerebrovascular disease, smoking, residence, solitary life, and walking disorder of patients between the two groups were compared, and the data were statistically analyzed with t test and chi-square test. Log-rank test was performed on the indexes with P<0.1 in comparison between two groups, and the indexes with statistically significant differences in Log-rank test were analyzed by multivariate Cox regression analysis to screen the influencing factors of recurrence of diabetic foot ulcer. Results: (1) The 3-year cumulative recurrence rate of diabetic foot ulcers in 185 patients with type 2 diabetes mellitus was 47.0% (87/185). (2) For 87 patients with diabetic foot ulcer recurrence, compared with that at the initial onset of the ulcers, the visit time was significantly shorter (t=10.593, P<0.01), the toe amputation rate was significantly increased (χ(2)=5.118, P<0.05), but there was no obvious change in toe involvement at the recurrence of the ulcers. (3) There were statistically significant differences in age, course of diabetes mellitus, length of hospital stay, body mass index, glycosylated hemoglobin HbA1c, total bilirubin, albumin, creatinine, cholesterol, LDL, HDL, hemoglobin, white blood cell count, gender, toe amputation, ankle-brachial index, DR, history of cardio-cerebrovascular disease, solitary life, and walking disorder of patients between foot ulcer recurrence group (87 patients) and foot ulcer non-recurrence group (98 patients) (t=5.123, 4.242, 5.324, -24.572, 6.102, -1.984, -9.747, 3.226, 3.076, 3.646, -4.683, -7.502, 8.095, χ(2)=5.621, 18.433, 4.546, 5.785, 9.655, 7.625, 7.886, P<0.05 or P<0.01), while the rest of the indexes of patients between the two groups were similar. Log-rank test showed that the two groups had statistically significant differences in age, course of diabetes mellitus, length of hospital stay, glycosylated hemoglobin HbA1c, total bilirubin, albumin, creatinine, ankle-brachial index, DPN, and walking disorder (χ(2)=210.046, 44.837, 34.107, 98.685, 66.532, 294.451, 260.554, 5.012, 6.818, 11.160, P<0.05 or P<0.01). Age, total bilirubin, albumin, DPN, and walking disorder were the influencing factors for the recurrence of diabetic foot ulcers in patients with type 2 diabetes mellitus (hazard ratio=1.024, 0.678, 0.849, 2.335, 4.099, 95% confidence interval=1.001-1.047, 0.558-0.823, 0.797-0.904, 1.280-4.258, 2.044-8.223, P<0.05 or P<0.01). Conclusions: The 3-year cumulative recurrence rate of diabetic foot ulcers in patients with type 2 diabetes mellitus is relatively high, with the influencing factors being age, total bilirubin, albumin, DPN, and walking disorder.

Abstract
In order to enhance the high-power performance of the ferrite phase shifter (PS), a method of increasing waveguide height is proposed and experimentally demonstrated. Dual-toroid geometry is utilized as a high-power structure. Two configurations of X-band PSs with full-height (FH) and increased-height (IH) waveguides are designed and fabricated while keeping other parameters consistent. Comparative analysis based on simulation and high-power experiments is conducted. The simulation results agree well with experiments. Compared with the FHPS, the IHPS can enhance the peak-power-capacity from 90 kW to 140 kW while maintaining almost the same insertion loss of 0.5 dB with a slight increase in differential phase shift from 360° to 380°.

Abstract
Objective: To evaluate the cost-benefit and cost-effectiveness of current strategy for preventing mother-to-child transmission (PMTCT) of hepatitis B virus. Methods: A decision tree model with the Markov process was developed and simulated over the lifetime of a birth cohort in Zhejiang Province in 2016. The current PMTCT strategy was compared with universal vaccination and non-vaccination. Costs were assessed from social perspective. Benefits were the savings from reduced costs associated with disease and effectiveness were measured by quality-adjusted of life-years (QALY) gained. The net present value (NPV), cost-benefit ratio (BCR) and incremental cost-effectiveness ratio (ICER) were calculated. Univariate and Probabilistic Sensitivity Analyses (PSA) were performed to assess parameter uncertainties. The parameters of costs and utilities value of hepatitis B-related disease came from the results of the field survey, which were obtained by face-to-face questionnaire survey combined with inpatient medical records, including eight county and municipal hospitals in Jinhua, Jiaxing and Taizhou. A total of 626 outpatients and 523 inpatient patients were investigated. The annual total costs of infection was calculated by combining the costs of outpatient and inpatient. Results: The PMTCT strategy showed a net-gain as 38 323.78 CNY per person, with BCR as 21.10, which was higher than 36 357.80 CNY per person and 13.58 respectively of universal vaccination. Compared with universal vaccination, the PMTCT strategy would save 2 787.07 CNY per additional QALY gained for every person, indicating that PMTCT would be cost-saving. The most important parameters that could affect BCR and ICER were the vaccine coverage rate and costs of hepatitis B related diseases respectively. The PSA showed the PMTCT strategy was preferable as it would gain more QALY and save costs. Conclusions: The PMTCT strategy appeared as highly cost-beneficial and highly cost-effective. High vaccination rate was a key factor of high economic value.

Abstract
Objective: To evaluate the post-marketing safety of inactivated Enterovirus type 71 (EV-A71) vaccine (human diploid cell) . Methods: A total of 20 191 healthy children aged 6 to 59 months were invited to receive 2 doses of EV-A71 vaccine in Zhejiang Province from September 2016 to December 2017. Child caregivers were followed up on the 4(th) or 5(th) day after each EV-A71 vaccination, and the incidence of local, systemic, and other adverse events within 3 days after vaccination was recorded to assess vaccine safety. Describe the differences in adverse events among children with different characteristics. Results: A total of 32 230 doses were observed in this study, of which 20 191 and 12 039 were vaccinated for the first and the second dose, respectively; and the incidence of adverse events within 3 days was 2.045% (413 doses) and 1.611% (194 doses), respectively. After the first and the second dose, the number of systemic adverse events was the highest, 371 and 175 cases, respectively, with an incidence of 1.837% and 1.454%, respectively; the number of local adverse events was the lowest, 14 and 2 doses, respectively, with an incidence of 0.069% and 0.017%. Local adverse events occurred after vaccination were generally mild, and only 2 patients had level of 3; among the systemic adverse events, 39 patients had a fever level of 3 or higher, accounting for 8.2% of the total fever. Most of the symptoms in the local adverse events did not require treatment, only 3 cases of vaccination site rash and 2 cases of pruritus were self-purchased drugs or outpatient treatment; except for 5 cases of fever, the other symptoms were not hospitalized in the case of systemic adverse events. Conclusion: The incidence of adverse events within 3 days after vaccination with EV-A71 vaccine was low in children, mainly systemic adverse events, and the prognosis was good.

Abstract
The process of globalization increases the risk of global transmission of infectious diseases, resulting in pressure for country's prevention and control of imported infectious disease. Based on the risk assessment of disease importation and local transmission, a strategy that conducting importation prevention and routine prevention and control before the importation of disease and taking emergency control measures after the importation of disease was developed. In addition, it is important to take part in global infectious disease response action, aid the countries with outbreak or epidemic to actively decrease the risk of disease importation.

Abstract
Objective: To assess the 3-year antibody persistence after vaccination of domestic measles, mumps and rubella combined attenuated live vaccine (MMR) with different program. Methods: Children from three different vaccination strategies (Group 8 m MR: 8 months and 18 months vaccinated with measles-rubella combined attenuated live vaccine and domestic MMR,respectively; Group 8 m MMR: 8 months and 18 months both vaccinated with domestic MMR; Group 12 m MMR: 12 months and 22 months both vaccinated with domestic MMR ) were followed up in Zhejiang province in July 2015. There were 170 participants in Group 8 m MR, 171 participants in Group 8 m MMR and 173 participants in Group 12 m MMR selected by simple random sampling method .Blood samples (venous blood 2-3 ml) were collected 1 month after the first dose vaccination of MMR (only in Group 8 m MMR and Group 12 m MMR) and 3 years (36-38 months) after the last dose vaccination of MMR and tested for antibody IgG against Measles, Mumps and Rubella using ELISA. Seropostive rate and Geometric mean concentration (GMC) were calculated and compared among different groups by Chi-square test or Fisher exact test and Kruskal-Wallis H test. Results: A total of 514 participants (8 m MR: 170; 8 m MMR:171; 12 m MMR:173) were enrolled. The overall seropositivity rate of measles, mumps and rubella was 98.1% (504), 93.4% (480) and 88.1% (453), respectively, with corresponding GMC was 1 012.33 mU/ml, 502.87 U/ml and 50.53 U/ml respectively. There was no significant difference of seropositivity rate for measles among three groups (all groups were>97%). The highest seropositivity rate for mumps was found in the Group 12 m MMR with the rate of 98.8% (171/173), followed by Group 8 m MMR and Group 8 m MR with 93.0% (159/171) and 88.2%(150/170) respectively (Fisher exact test, P<0.001). The highest seropositivity rate for rubella was also found in the Group 12 m MMR with the rate of 94.8% (164/173), followed by Group 8 m MMR and Group 8 m MR with 86.6%(148/171) and 82.9%(141/170) respectively (Fisher exact test, P=0.002). The highest GMC of antibody against measles, mumps and rubella were all found in Group 12 m MMR, with 1 217.30 (1 119.35-1 323.82) mU/ml, 717.07 (643.83-798.65) U/ml and 62.54(56.21-69.58) U/ml respectively. The lowest GMC of antibody against measles and mumps were both in Group 12 m MR with 812.01 (734.52-897.67) mU/ml and 363.28 (305.42-432.11) U/ml respectively. The lowest GMC of antibody against rubella was in Group 8 m MMR with 44.10 (39.08-49.76) U/ml. These differences of GMCs among three groups were all reach significant means (P<0.05). Conclusion: High level seropostive rates and GMCs were exist against measles and rubella after 3-year vaccination of domestic MMR among different program. Higher antibody level against mumps were found in those children with two doses vaccination of MMR.

Abstract
OBJECTIVE To evaluate the economic effect of Measles, Mumps and Rubella Combined Attenuated Live Vaccine (MMR) under different two-dose vaccination programs. METHODS A hypothetical birth cohort of 750 000 infants over their lifetime, was followed up from birth through death in Zhejiang province. The current MMR vaccination strategie would include three different ones: 1) Childlern were vaccinated with Measles-Rubella Combined Attenuated Live Vaccine and MMR, respectively at the age of 8 months and 18 months. 2) Children receive MMR at 8 months and 18 months, 3) Strategy 1 plus an additional vaccination of MMR at 4 years of age. Incremental cost-effectiveness ratio (ICER), incremental cost-benefit ratio (ICBR) and incremental net benefit (INB) were applied to calculate the health economic difference for Strategy 2 and Strategy 3 as compared to Strategy 1. Univariate sensitivity analysis was used to assess the robustness of results with main parameters, including the rate of immunization coverage, effectiveness of the vaccines, incidence and burdens of the related diseases, cost of vaccines and the vaccination program itself. RESULTS ICER, ICBR and INB for Strategy 2 and Strategy 3 appeared as 2 012.51∶1 RMB Yuan per case and 4 238.72∶1 RMB Yuan per case, 1∶3.14 and 1∶1.58, 21 277 800 RMB Yuan and 9 276 500 RMB Yuan, respectively. Only slight changes (<20%) were found under the univariate sensitivity analysis, with varied values on main parameters. CONCLUSION Based on the current national immunization program, infants vaccinated with MMR at 8 months of age, generated more health economic effects than the Strategy 3.

Abstract
This study aimed to enhance the antibacterial activity of tilmicosin by solid lipid nanoparticles (SLN). Tilmicosin-loaded hydrogenated castor oil (HCO)-SLN was prepared using a hot homogenisation and ultrasonication method. The physicochemical characteristics of SLN were investigated by scanning electron microscopy (SEM) and photon correlation spectroscopy (PCS). The antibacterial activity of tilmicosin-SLN against Staphylococcus aureus was evaluated by growth inhibition and colony-counting method. A therapeutic study of tilmicosin-SLN was conducted by subcutaneous injection in a mouse mastitis model infected with S. aureus by teat canal infusion. Therapeutic efficacy was assessed by physical appearance of the mammary gland and measurement of colony-forming units (CFU) per gland. The results showed that the diameter, polydispersivity index, zeta potential, encapsulation efficiency and loading capacity of the nanoparticles were 343±26 nm, 0.33±0.08, -7.9±0.4 mV, 60.4±3.3% and 11.2±0.47%, respectively. Tilmicosin-SLN showed a sustained-release effect and sustained and enhanced antibacterial activity in vitro. SLN significantly enhanced the therapeutic efficacy of tilmicosin determined by lower CFU counts and a decreased degree of inflammation. These results demonstrated that the HCO-SLN is an effective carrier to enhance the antibacterial activity of tilmicosin.

Abstract
It is well known that TP53 may mediate apoptosis triggered by anticancer drugs. However, accumulating evidence indicates that TP53 may be inactivated by mutations and/or deletions in about 50% of human cancers and, as such, may lead to pronounced resistance to therapeutic agents. Thus, the development of new approaches to improve the efficiency of therapeutic agents in cancer cells harboring mutant TP53 may have a significant impact on cancer treatment. It has been reported that knockdown by RNA interference (RNAi) of p28GANK (an alias of the gene PSMD10), a novel oncogene over-expressed in hepatocellular carcinoma (HCC), can induce apoptosis in HepG2, a TP53-intact HCC cell line. Because of the high frequency TP53 mutations in HCC, it is relevant to know whether p28GANK knockdown-induced apoptosis is also operational in TP53-negative HCC cells. Here, we investigated Adsip28GANK-induced apoptosis in the TP53-negative HCC cell line Hep3B. Our results indicate that p28GANK-knockdown induces the generation of reactive oxygen species (ROS), which in turn activates p38. Since p38 can signal to Bax, its activation may lead to mitochondrial transmembrane potential (Delta psi m) loss, cytochrome c release from mitochondria to cytosol, and caspase-9 activation, eventually triggering the mitochondrial pathway of apoptosis.

Abstract
Simultaneous separation and identification of perchlorinated polycyclic aromatic hydrocarbons (PCPAHs) and fullerenes is of practical interest due to the growth mechanism of fullerenes involved with PCPAHs. Non-aqueous reversed-phase high-performance liquid chromatography (HPLC), with an ODS column and a gradient mobile phase of methanol-ethanol-cyclohexane mixtures, was combined with both rapid-scan ultraviolet spectrometry (UV) and atmospheric pressure chemical ionization mass spectrometry (APCI-MS) for the separation and identification of over 80 PCPAHs as well as fullerenes C60 and C70, that were synthesized in the discharge reaction of chloroform. PCPAH retention was found to depend on the number of aromatic rings and the degree of non-planarity of PCPAH structure. Based on the isotopic pattern of molecular ion or/and quasi-molecular ion peaks in corresponding mass spectra, molecular compositions of the PCPAH products were unambiguously determined. The results obtained from the HPLC-UV-MS analysis not only are helpful for the understanding of the fullerenes formation mechanism, but also contribute to the analytical technique capable of separating and identifying the complicated mixture of PCPAHs and fullerenes.

Abstract
With -1000 genes, the odorant receptor (OR) gene repertoire is the largest gene family in the mouse genome. Here we have established a 129/Sv BAC contig for mouse OR gene cluster 7 (Olfr7) on Chromosome (Chr) 9. The assembled approximately 2-Mb contig consists of 75 BACs and may contain as many as 100 OR genes, or approximately 10% of the mouse repertoire. Facilitated by the lack of introns in the coding region, we have determined the nucleotide sequence of 37 full-length, 2 partial, and 3 pseudo coding regions. These 42 OR genes and 3 additional OR genes previously mapped to the mouse Olfr7 cluster can be organized into 13 classes based on OR probe cross-hybridizations with 129/Sv mouse genomic DNA. OR genes belonging to the same class tend to be located next to each other within the cluster. Comparison of published full-length mouse and rat OR coding sequences with those identified here shows that the Olfr7 OR genes are highly related to each other, clustering on two major branches of an unrooted phylogenetic tree. Eight ORs contain an unusual NXC sequon at the amino-terminal extracellular domain that may represent a novel N-linked glycosylation site. The BAC contig presented here provides the substrate for sequencing of the cluster.

Abstract
High-performance liquid chromatography (HPLC) was coupled with ultraviolet absorption spectroscopy (UV) for the simultaneous separation and identification of a series of perchlorinated polycyclic aromatic hydrocarbons, such as perchlorobenzene (C6Cl6), perchloronaphthalene (C10Cl8), perchlorobiphenyl (C12Cl10), perchloroanthracene (C14Cl10), perchlorophenanthrene (C14C10), perchloroacenaphthylene (C12Cl8), perchloropyrene (C16Cl10) and perchlorofluoranthene (C16Cl10). HPLC was performed on an ODS column using methanol-hexane (80:20) as mobile phase at a flow-rate of 1.0 ml/min. UV absorption spectra of the elutes were detected in the region of 210-350 nm.

Abstract
The effects of reserpine on the blood pressure, heart rate, higher nervous activity and plasma catecholamine level during the development of neuropsychogenic hypertension induced by overstrain of the central nervous system have been studied in dogs. Overstrain (intensified tension) of the higher nervous activities was induced by a schedule or irregularly arranged strengthening of the conditional stimuli with electric stimuli on the skin. After completion of three stimulative periods, 4 of the 5 untreated control and 2 of the 5 reserpine-treated dogs were found to have developed hypertension. The blood pressure measured in Chamber A (the room for blood pressure measurement) was much lower than that measured in Chamber B, i.e. in the experimental environment. The results showed that reserpine may have some inhibitory influence on the development of this model of neuropsychogenic hypertension, yet it could not prevent its development completely.
