Abstract
Improving the humification of compost through a synergistic approach of biotic and abiotic methods is of great significance. This study employed a composite reagent, comprising Fenton-like agents and effective microorganisms (EM) to improve humification. This composite reagent increased humic-acid production by 37.44 %, reaching 39.82 g kg-1, surpassing the control group. The composite reagent synergistically promoted micromolecular fulvic acid and large humic acid production. Collaborative mechanism suggests that Fenton-like agents contributed to bulk residue decomposition and stimulated the evolution of microbial communities, whereas EMs promoted highly aromatic substance synthesis and adjusted the microbial community structure. Sequencing analysis indicates the Fenton-like agent initiated compost decomposition by Firmicutes, and EM reduced the abundance of Virgibacillus, Lentibacillus, and Alcanivorax. Applied as an organic fertilizer in Brassica chinensis L. plantations, the composite reagent considerably improved growth and photosynthetic pigment content. This composite reagent with biotic and abiotic components provides a learnable method for promoting humification.

Abstract
Objective: To investigate the surgical efficacy of split liver transplantation. Methods: Patients who underwent liver transplantation at the Affiliated Hospital of Qingdao University between January 2015 and December 2022 were retrospectively analyzed. They were divided into split liver transplantation group (n=60) and whole liver transplantation group (n=765)according to graft types.In the split liver transplantation group, there were 23 males and 37 females, aged (52.5±10.2) years, and the body mass index was (22.4±3.3) kg/m2. In the whole liver transplantation group, there were 630 males and 135 females, aged (51.2±9.6) years, and body mass index was (24.5±3.7) kg/m2.The basic data of the two groups were matched 1∶1 using the propensity score matching method. The independent sample t test and χ2 test were used to compare the intraoperative and postoperative recovery of the two groups of donors and recipients. The overall survival rate and the graft survival rate of the two groups were analyzed by Kaplan-Meier method and the cumulative survival rate was compared by the Log-rank test. Results: Fifty-one well-matched pairs of data with similar baseline characteristics were obtained. The ratio of graft mass to recipient body weight in the matched split liver transplantation group was (1.78±0.55)%. Operation time(M(IQR))(10.8(1.5)hours vs. 8.0(1.9)hours,U=6.608,P<0.01) and cold ischaemia time(5.4(1.3)hours vs. 4.6(2.2)hours,U=2.825,P=0.005) were significantly longer in the split liver transplantation group than those in the whole liver transplantation group. Intra-operative anhepatic phase(53.0(15.0)minutes vs. 57.0(24.0)minutes,U=1.048,P=0.295),bleeding volume(1 000(1 400)ml vs. 1 200(1 200)ml,U=0.966,P=0.334) and intraoperative instillation of red blood cells(9.0(6.5)U vs. 11.0(11.0)U,U=1.732,P=0.083) were not significantly different between the two groups. However,the split liver transplantation group showed significantly longer postoperative intensive care unit stay(5.0(3.0)days vs. 4.0(4.0)days,U=2.677,P=0.007) and postoperative hospital stay(30.0(15.0)days vs. 26.0(15.0)days,U=2.237,P=0.025) and significantly higher incidence of postoperative complications(56.8%(29/51) vs. 36.6%(19/51),χ2=3.935,P=0.047) than the whole liver transplantation group. Furthermore,levels of alanine transaminase and aspartate aminotransferase were significantly higher on postoperative days 1,4 and 7 in the split liver transplantation group(all P<0.05) than in the whole liver transplantation group;however,there were no significant differences in these levels on postoperative days 14 and 28. The time to restoration of normal liver function in both groups(12.5(13.7)days vs. 9.0(12.5)days,U=1.607,P=0.108) was not statistically significant. Furthermore,the median follow-up time after surgery was 25.6 months in both groups. In postoperative years 1,2,3 and 5, the graft survival rates were 88.1%,80.8%,77.8% and 66.7% in the whole liver transplantation group and 80.3%,70.3%,67.3% and 60.5% in the split liver transplantation group(P=0.171),respectively. The patient survival rates in post-operative years 1,2,3 and 5 were 88.1%,80.8%,77.8% and 66.7% in the whole liver transplantation group and 80.3%,75.9%,70.3% and 63.3% in the split liver transplantation group,respectively(P=0.252). However,the differences of graft survival rates and patient survival rates between the two groups were not significant. Conclusion: Although it affects the early recovery of patients after liver transplantation,split liver transplantation has no effect on long-term survival rates and demonstrates surgical efficacy similar to that of whole liver transplantation.

Abstract
Objective: To evaluate the effect of transfusion-free techniques on the prognosis of liver transplant patients. Methods: The recipients of adult liver transplantation at Tianjin First Central Hospital from August to December 2019 were included in the clinical observation. Liver transplantation without allogeneic blood transfusion was performed through anesthesia management techniques such as acute hemodilution or phlebotomy without volume replacement,maintaining decreased baseline central venous pressure and cell saver. According to the actual results,the patients were divided into two groups: transfusion-free group(n=21) and allogeneic transfusion group(n=28). There were 13 males and 8 females aged of (56.3±11.6) years in the transfusion-free group;and there were 16 males and 12 females aged (54.3±14.2)years in the allogeneic transfusion group. The transplant recipients who had not adopted transfusion management strategy from January to July 2019 were included as control group(27 males and 13 females,aged of (58.9±14.1)years). The clinical data of patients in perioperative period were collected to compare whether there were differences in the recovery of liver function and early complications among the three groups, one-way ANOVA test, rank-sum test, and χ2 test were used for data analysis. Results: The amount of intraoperative blood loss in both the transfusion-free group and the transfusion group was less than that in the control group((454.2±271.3)ml vs.(673.6±333.4)ml vs.(890.3±346.7)ml;q=-6.342,-5.286,both P<0.05).The duration of stay in ICU of the transfusion-free group was less than that of the transfusion group and control group((36.4±9.1)hours vs.(44.3±14.9)hours vs.(58.2±21.1)hours;q=-4.432,-3.824,both P<0.05).The mean ALT level at 7 days after operation was significantly lower in the transfusion-free group than in the control group((56.8±32.1)U/L vs.(89.6±45.6)U/L;q=-3.358,P<0.05). Conclusions: The improvement of multi-disciplinary transfusion management technology aimed at transfusion-free liver transplantation can effectively reduce intraoperative hemorrhage and help to avoid surgical transfusion. Transfusion-free liver transplantation is beneficial to the early postoperative recovery,and its long-term clinical significance is worthy of further clinical research.

Abstract
Objective: To investigate the relationship between psoas muscle index (PMI) and early postoperative survival rate and the incidence of complications after liver transplantation in adults. Methods: The clinical data of 225 patients (male, n=184; female, n=41) underwent liver transplantation at the Organ Transplantation Department of First Central Clinic Institute of Tianjin Medical University from January 2014 to December 2016 were analyzed, retrospectively.Original disease: hepatitis B liver cirrhosis(44 cases), hepatitis C cirrhosis(10 cases), autoimmune liver cirrhosis(29 cases), other benign liver diseases(24 cases), liver cirrhosis with liver cancer(116 cases), hilar cholangiocarcinoma(1 case) and hepatic vascular sarcoma(1 case). The area of bilateral psoas muscle on the lower edge level of the third lumbar vertebral body was measured through preoperative CT image.The PMI was calculated using this formula: bilateral psoas muscle area (mm(2))/the square of the body height (m(2)). According to the receiver operating characteristic curve and cut-off values, the male and female patients were divided into low PMI group and high PMI group respectively.The χ(2) test, Fisher exact test and t-test was used to compare the differences in perioperative data, survival rate and postoperative complications between the two groups, respectively. Results: There were 44 patients in the low PMI group, and 181 patients in the high PMI group. ICU time was longer (82.5(62.0-128.0) hours vs.69.1(56.0-104.0) hours; P=0.006) and preoperative blood urea nitrogen level (5.86(4.35-15.52) mmol/L vs. 4.94(4.05-7.06) mmol/L; P=0.012) was higher in the low PMI group than those in the high PMI group. Incidence rates of grade 5 complication (18.2%) and grade 4a complication (18.2%) were higher in the low PMI group, and 120-day cumulative survival rate was lower than that in high PMI group(81.8% vs. 95.6%, P=0.001). On the other hand, there were no significant differences in preoperative white blood cell count level, serum creatinine level, operative time, anhepatic period time, intraoperative blood loss, and incidence of postoperative grade 3 complications between the two groups(all P>0.05). Conclusions: There is a significant correlation between PMI and early postoperative survival rate and incidence of complications.Patients with lower PMI has poor prognosis after liver transplantation.

Abstract
The plasma pharmacokinetics and mammary excretion of eprinomectin were determined in dairy yaks following topical administration at a dose of 0.5 mg/kg. The kinetics of plasma and milk concentrations were analyzed using a noncompartmental model. Plasma and milk concentrations of eprinomectin increased to reach maximal concentrations of 5.45 ± 2.84 and 2.29 ± 0.90 ng/mL at a Tmax of 1.79 ± 0.57 and 2.00 ± 0.82 days, respectively. The concentration of eprinomectin in plasma was remained >0.5 ng/mL for more than 30 days after administration. The mean residence times of eprinomectin in plasma and milk were 14.73 ± 6.22 and 9.37 ± 2.81 days, respectively. The AUC value in plasma (55.89 ± 18.16 ng day/mL) was threefold greater than that in milk (18.02 ± 6.48 ng day/mL). The AUC milk/plasma ratio was 0.33 ± 0.08. The systemic availability of eprinomectin in yaks was lower than that observed value in other domestic bovines. The low level of eprinomectin excretion in milk suggests that eprinomectin can be used in yaks with zero milk-withdrawal time. The efficacy of eprinomectin against naturally acquired larvae of Hypoderma spp. was also determined in yaks. Topically administrated eprinomectin at a dose of 0.5 mg/kg was 100% efficacious against larvae of Hypoderma bovis, H. lineatum, and H. sinense.

Abstract
We applied hydrostatic pressure (up to 10 GPa) to single-walled carbon nanotube bundles at low temperature (down to 2 K) to measure their magnetoresistance (MR) in a field up to 12 T. We found a pressure-induced transition in MR from positive to negative in the high-field regime. The onset of the transition occurs at approximately 1.5 GPa, which correlates closely with the tube shape transitions. The characteristics of the high-pressure MR are consistent with a model of pressure-induced two-dimensional weak localization.

Abstract
BACKGROUND Refractory rejection is a major cause of morbidity and death among lung transplant recipients. Traditional rescue therapies have proved only modestly successful. We recently demonstrated the safety of inhaled cyclosporine for patients with end-stage chronic rejection; this trial was extended to patients with refractory acute rejection. The present study was to determine whether effective inhaled cyclosporine therapy was correlated with suppression of cytokine gene expression. METHODS Twelve lung transplant recipients were studied. Maintenance therapy, cyclosporine or FK 506, azathioprine, and prednisone, was continued, and inhaled cyclosporine at a dose of 300 mg/day was added. Pulmonary function testing and histologic characteristics from transbronchial biopsy specimens were used to assess efficacy of therapy. Bronchoalveolar lavage (BAL) and peripheral blood cells were analyzed for the presence of messenger RNA by using 32P-labeled primers of cytokines interleukin-2 (IL-2), IL-6, IL-10, and interferon-gamma (gamma) via reverse transcriptase-polymerase chain reaction. RESULTS Nine of 12 patients (five with acute rejection, four with chronic rejection) exhibited histologic resolution of rejection within 3 months of inhaled cyclosporine therapy. Pulmonary function (forced expiratory volume in 1 second) improved from pretherapy levels in the patients with acute rejection (p < 0.05). All of the nine histologic responders exhibited 4- to 150-fold decreases (p < 0.05) in IL-6 and interferon-gamma messenger RNA levels in the BAL, whereas the three patients who failed exhibited persistent or increased cytokine profiles. IL-2 and IL-10 in BAL and peripheral blood lymphocyte cytokines were not informative. CONCLUSIONS These results indicate that inhaled cyclosporine is effective therapy for refractory pulmonary rejection and that its mechanism of action is associated with suppression of proinflammatory cytokines IL-6 and interferon-gamma within the allograft.
