Abstract
As a chronic infectious disease, tuberculosis (TB) is closely related to immune regulation and immune effect. Immunotherapy which can improve the curative effect of tuberculosis and control the spread of tuberculosis, is one of the important means for the comprehensive treatment of tuberculosis. From October 2022 to September 2023, research on the immunotherapy of tuberculosis at home and abroad continues to increase, providing new opportunities for the treatment of multidrug-resistant and extensively drug-resistant tuberculosis. Host-targeted therapy and therapeutic vaccines are new directions for research into TB adjuvant therapy.

Abstract
OBJECTIVE With the change in drug-resistant pattern, MDR/RR-TB was faced with underlying changes in regimens. A multi-center, large-scale, retrospective study performed aims to provide a recommendation of drug selection on optimization of outcome for the patients. METHOD The study was conducted in six TB-specialized hospitals in China. Patients were included from 2018-2021 and followed up throughout the treatment. Using a multivarariable and propensity score-matched logistic regression analysis, we evaluated associations between outcomes and drug use, as well as clinical characteritics. RESULTS Of 3112 patients, 74.29% had treatment sucess, 14.52% lost to follow-up, 9.67% failure, and 1.51% died. Treatment success was positively associated with Bedaquiline(Bdq), Linezolid(Lzd), and Cycloserin(Cs). Capreomycin(Cm) increased the risk of unfavorable outcomes. other drugs such as Amikacin(Amk) and clofazimine had no significant effect on outcomes. If isolates were susceptible to fluoroquinolones(FQs), FQs could decrease the risk of unfavorable outcomes. CONCLUSIONS The recommendation order for the treatment of MDR/RR-TB is Bdq, Lzd, and Cs. FQs were decreased in use intensity. Injection drugs, whether Amk or Cm, are not recommended.

Abstract
PURPOSE We retrospectively evaluate the diagnostic performance of 2-deoxy-2[18F]fuoro-D-glucose([18F]F-FDG) PET/CT and its impact on clinical management in patients with suspected paraneoplastic dermatoses (PD). MATERIALS AND METHODS From an institutional PET/CT database (2014-2022), we retrospectively analyzed patients who were clinically suspected with PD and underwent [18F]F-FDG PET/CT for screening an underlying malignancy. For all scans, positive mucocutaneous lesions and PET-indicated malignancies were assessed, and the degree of FDG avidity among different dermatoses were quantified. The final diagnoses of dermatoses and neoplasms were based on pathologic results, international diagnostic standard and follow-up. We assessed the recommended and applied therapies before and after [18F]F-FDG PET/CT and noted whether the patient management changed on the basis of the [18F]F-FDG PET/CT results. RESULTS We analyzed 60 patients with 10 types of dermatoses in this study. Finally, 19 of the 60 patients who had both of specific dermatosis and contemporaneous neoplasm were diagnosed with PD. [18F]F-FDG PET could identify the underlying neoplasms in 18/19 (94.7%) PD patients, and led to a change of the management in 9/19 (47.4%) PD patients. In addition, the mucocutaneous manifestations of [18F]F-FDG PET/CT associated with several specific dermatoses were characteristic. CONCLUSIONS This study highlighted the value of [18F]F-FDG PET/CT as a useful tool for evaluation of patients with suspected PD to unveil the underlying culprit tumor, and profoundly supports the clinical management of PD patients.

Abstract
ABSTRACTThe World Health Organization has identified high-priority target product profiles for new TB diagnostics which include rapid biomarker-based, non-sputum-based diagnostic testing, using an easily accessible sample. The Cepheid 3-gene Host Response Fingerstick Blood Prototype Test (MTB-HR) quantifies relative mRNA levels of a 3-gene signature (GBP5, DUSP3, and KLF2) from a whole-blood sample on the GeneXpert platform. The objective of the present study was to evaluate the performance of the MTB-HR to distinguish between active tuberculosis (ATB), latent Mycobacterium tuberculosis infection (LTBI), other pulmonary diseases, and healthy volunteers at a tertiary care centre. Among 653 participants enrolled in this study, 192 were diagnosed as having ATB, and the remaining 461 were classified as non-ATB, including 137 cases of LTBI, 224 cases of other pulmonary diseases, and 100 healthy volunteers. The corresponding AUCs of the MTB-HR in distinguishing untreated ATB from non-ATB, LTBI, other pulmonary diseases, and healthy volunteers were 0.814 (95% CI, 0.760-0.868, sensitivity 76.1%, specificity 71.6%), 0.739 (95% CI, 0.667-0.812, sensitivity 59.7%, specificity 78.1%), 0.825 (95% CI, 0.770-0.880, sensitivity 82.1%, specificity 65.6%), 0.892 (95% CI, 0.839-0.945, sensitivity 76.1%, specificity 88.0%), respectively. When only samples with TAT of less than 1 h were included, the AUC of the MTB-HR in distinguishing untreated ATB from non-ATB was largest, 0.920 (95% CI, 0.822-1.000, sensitivity 81.3%, specificity 87.7%). In conclusion, the MTB-HR assay shows potential as a rapid, blood-based screening and triage test for ATB, especially for untreated ATB, with the advantage of increased diagnostic yield since blood is more readily available.

Abstract
Objective To evaluate the safety, tolerability, and efficacy of prolonged bedaquiline (Bdq) treatment in patients with multi-drug/rifampin-resistant tuberculosis (MDR/RR-TB). Methods This prospective cohort study was performed from August 2018 to August 2021. Patients diagnosed with MDR/RR-TB who met the inclusion criteria were prospectively included. Patients were treated with individual regimens of 18-20 months containing Bdq for six months or a prolonged course of nine or 12 months according to treatment demands, and the efficacy and safety with a different course of Bdq-containing regimens were compared and evaluated. Results A total of 159 MDR/RR-TB patients were included in the study, including 96 cases with six months of Bdq, 50 cases with nine months of Bdq, and 13 patients with 12 months of Bdq. The treatment success rates were 89.6%, 90%, and 84.6% in Bdq at six months, nine months, and 12 months, respectively, which were not statistically different (P = 0.85). The main adverse events (AEs) were anemia, thrombocytopenia, and liver dysfunction in all patients, with no significant difference among the three groups. Patients who had fewer drugs chosen, disseminated lesions or lesions that were slowly absorbed, and severe cavities were the common reasons for prolonged use of Bdq. Conclusion Prolonged course use of Bdq from six months to 12 months clinically proved to be safe and efficient, and patients with severe or disseminated lesions had the chance to prolong the use of Bdq for more than six months to achieve optimal treatment outcomes.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Huangqin Tang (HQT), a famous prescription with the effect of clearing pathogenic heat and detoxifying, was first recorded in "Treatise on Typhoid and Miscellaneous Diseases". It has proved that HQT has good anti-inflammatory and antioxidant effects and can improve acne symptoms clinically. However, the study on the regulation of HQT on sebum secretion which is one of the inducements of acne is not enough. AIM OF THE STUDY This paper aimed to investigate the mechanisms of HQT in the treatment of skin lipid accumulation by network pharmacology and validating the results via in vitro experiments. MATERIALS AND METHODS Network pharmacology was employed to predict the potential targets of HQT against sebum accumulation. Then, the palmitic acid (PA)-induced SZ95 cell model was established to evaluate the effect of HQT on lipid accumulation and anti-inflammation, and the core pathways predicted by network pharmacology were verified in cell studies. RESULTS 336 chemical compounds and 368 targets in HQT were obtained by network pharmacology, of which 65 targets were related to sebum synthesis. 12 core genes were revealed by protein-protein interaction (PPI) network analysis. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment results suggested that AMP-activated protein kinase (AMPK) signaling pathway might play a crucial role in regulating lipogenesis. In vitro experiments, HQT suppressed lipid accumulation, downregulated the expressions of sterol-regulatory element binding protein-1 (SREBP-1) and fatty acid synthase (FAS), and upregulated AMPK phosphorylation. Furthermore, AMPK inhibitor reversed HQT-mediated sebosuppressive effect. CONCLUSION The results disclosed that HQT ameliorates lipogenesis in PA-induced SZ95 sebocytes partially through the AMPK signaling pathway.

Abstract
Pearl powder is a famous traditional Chinese medicine that has a long history in treating palpitations, insomnia, convulsions, epilepsy, ulcers, and skin lightining. Recently, several studies have demonstrated the effects of pearl extracts on protection of ultraviolet A (UVA) induced irritation on human skin fibroblasts and inhibition of melanin genesis on B16F10 mouse melanoma cells. To further explore the effect we focused on the whitening efficacy of pearl hydrolyzed conchiolin protein (HCP) on human melanoma MNT-1 cells under the irritation of alpha-melanocyte-stimulating hormone (α-MSH) or endothelin 1 (ET-1) to evaluate the intracellular tyrosinase and melanin contents, as well as the expression levels of tyrosinase (TYR), tyrosinase related protein 1 (TRP-1), and dopachrome tautomerase (DCT) genes and related proteins. We found that HCP could decrease the intracellular melanin content by reducing the activity of intracellular tyrosinase and inhibiting the expression of TYR, TRP-1, DCT genes and proteins. At the same time, the effect of HCP on melanosome transfer effect was also investigated in the co-culture system of immortalized human keratinocyte HaCaT cells with MNT-1. The result indicated that HCP could promote the transfer of melanosomes in MNT-1 melanocytes to HaCaT cells, which might accelerate the skin whitening process by quickly transferring and metabolizing melanosomes during keratinocyte differentiation. Further study is needed to explore the mechanism of melanosome transfer with depigmentation.

Abstract
Extracellular vesicles (EVs) are promising tools for drug delivery across different biological barriers. Here, we evaluated the potential of EVs-mediated delivery of CD38 siRNA on the immunosuppression of hepatocellular carcinoma (HCC). EVs were isolated from bone marrow mesenchymal stem cell culture medium and loaded with CD38 siRNA to prepare EVs/siCD38. Loss-of-function assays were conducted to investigate the biological functions of EVs/siCD38 in HCC cells. Xenograft mouse models were performed for further validation. High CD38 expression was found in HCC. EVs/siCD38 inhibited CD38 enzyme activity, decreased adenosine production, and promoted macrophage repolarization to M1 type, thus inhibiting HCC cell growth and metastasis in vitro as well as tumor growth in mice. Mechanistically, CD38 was upregulated in mice resistant to PD-1/PD-L1 inhibitor and EVs/siCD38 reversed the resistance of tumor to PD-1/PD-L1 inhibitor in vivo. Our results provide functional evidence for the use of EV-mediated delivery of CD38 siRNA to prevent immunosuppression feature of HCC.

Abstract
Objective It is a challenge to obtain satisfactory treatment outcomes for patients with multidrug-resistant/rifampicin-resistant tuberculosis (MDR/RR-TB); the study aims to correlate the Minimum Inhibitory Concentration (MIC) value of drugs with the outcome of patients with MDR/RR-TB to obtain an understanding for better regimens and optimal outcomes. Methods The patients diagnosed with MDR/RR-TB were retrospectively enrolled from January 1, 2018 to December 31, 2019, recorded clinical characteristics, MIC DST (Drug Susceptibility Test) results, and followed the treatment outcome. The data were analyzed on the correlations of MIC DST values with outcomes and clinical characteristics. Results A total of 276 patients with MDR/RR-TB were included, containing 98 cases (35.5%) with newly treated patients and 178 cases (64.5%) with re-treated patients. A total of 220 cases recorded treatment success (79.7%) and 49 cases recorded treatment failure or died. MIC values of isoniazid (H), moxifloxacin (Mfx), and ethionamide (Eto) in newly treated patients were lower than those in retreated patients, and resistance levels of Mfx and H were closely associated with the treatment outcome (P < 0.05) while those of other drugs had no close association with treatment outcome. Conclusions MIC values of some anti-TB drugs, such as fluoroquinolones (FQs) and H, can reflect the treatment outcome for patients with MDR/RR-TB, which can contribute to making regimens for better treatment outcomes.

Abstract
Ventilating solid waste landfills with an oxygen supply can effectively accelerate the degradation of waste, achieve rapid stabilization, and realize the sustainable utilization of landfills. Aiming to understand and verify the aerobic degradation process in landfills, this paper proposed a biochemical-thermal-hydro-mechanical coupling model. The model considers aerobic biochemical reactions, dissolved solute migration, heat transport, two-phase flow, and skeleton deformation. The model was verified by comparison with an in-situ experiment at Jinkou landfill. The results showed the model could accurately represent the observed degradation phenomena during the experiment. The modelling results indicated that the rate of temperature increase and peak temperature of the upper layer, which were lower than those of the middle layer, were affected by heat exchange at the landfill surface. The lowest temperatures occurred near the bottom because of high water content and low oxygen concentrations. The high temperature zone migrated out from the injection well during degradation, reflecting the degradation of degradable organic matter associated with oxygen diffusion rates and aerobic degradation reactions. The initial accumulated settlement value was fast, but slowed and finally stabilized. The surface subsidence also developed from the center around the injection well to the surrounding area, and 70% of the total subsidence occurred within 150 days. This newly developed model provides a theoretical framework for analyzing the multi-field coupling of aerobic degradation of landfilled municipal solid waste (MSW).

Abstract
BACKGROUND Gut microbiota play an important role in the inflammation. This study aimed to investigate whether exogenous probiotics could improve the intestinal barrier function effect via attenuating inflammation and immunomodulation to improve the clinical outcomes in critically ill patients. METHODS A single-blind, randomized controlled trial was performed in a respiratory intensive care unit (RICUs). Patients assigned to the intervention group received probiotics Clostridium butyricum until death or discharge. Stool and blood samples were collected on the 1st day and 15th day of administration. Primary clinical outcomes and clinical manifestations were recorded during the follow-up period. RESULTS There were 61 patients in this study, with 28 patients receiving probiotics. There were no differences in the mortality and hospital stay between intervention group and control group. In addition, the duration of fever (% of hospital stays) was significantly shorter in the intervention group as compared to control group (4.85% vs. 12.94%, P=0.00). The incidence of constipation significantly reduced in the intervention group (17.86% vs. 42.42%, P=0.04). The overall ratio of gastrointestinal adverse effects was comparable between them. Bactericides significantly decreased after probiotic intervention (Δm=-0.69, P=0.048), while Escherichia coli and Enterococcus tended to decrease in the intervention group (Δm=-0.65, P=0.08; Δm=-0.52, P=0.22) on the day 15. No fluctuation was observed in the Bifidobacterium and Lactobacillus after probiotic intervention. CONCLUSIONS Our study fails to show the beneficial effects of probiotics on the primary clinical outcomes in critically ill patients. The intestinal barrier is damaged, and probiotics may reduce the burden of Gm-bacteria from the gut.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE You-Gui-Yin (YGY) is a famous Chinese traditional medicine compound that has been used to treat renal function diseases for more than 300 years. It is recorded in Jing Yue Quanshu, which was written by a famous medical scientist named Jiebing Zhang in the Ming Dynasty. AIM OF THE STUDY Reproductive dysfunction is one of the most serious complications of chronic kidney disease (CKD). The aim of this study was to observe the effect of You-Gui-Yin (YGY) on reproductive dysfunction of male rats with adenine-induced CKD and to determine if any effects occurred via regulation of the HIF1α-STAT5 pathway. MATERIALS AND METHODS UPLC-Q-TOF-MS was used to detect the main medicinal components and conduct quality control of YGY. A total of 60 rats were randomly divided into 2 groups: the NC group (10 rats) and the CKD model group (50 rats). The CKD model rats was established by administration of adenine 150 mg kg-1 orally for 14 days. After that, the CKD rats were randomly divided into 5 groups: the CKD group, YGY (10 g kg-1 group, 20 g kg-1 group, 40 g kg-1 group) and the GUI-LU-ER-XIAN-JIAO (GL) 10 g kg-1 group with 10 rats in each group. From the 15th day to the 45th day rats were given 150 mg kg-1 adenine orally every other day to maintain the model (except in the NC group). The YGY groups and the GL group were orally administered the relevant drug once per day for 30 days. The NC group and the CKD group were orally administered an equal volume of normal saline for 30 days. On the 45th day, the rats' sexual behavior index was tested. On the 46th day, the rats were sacrificed. Biochemical indexes, histopathological changes of the kidneys and testes, sperm morphology, sperm abnormality rate, and key proteins in the HIF1α-STAT5 pathway in the kidney and testis were detected. RESULTS Thirteen components in the YGY extract were identified by UPLC-Q-TOF-MS for quality control of the YGY extract. The results of the biochemical and physiological tests validated the success of inducing CKD accompanied by reproductive dysfunction in rats. YGY significantly retarded the CKD progression and improved the hormone levels of male CKD rats. Sexual behavior tests showed YGY can significantly improve CKD rats' sexual function. In addition, the pathological changes of the kidney and testis, sperm abnormality rate and sperm morphological abnormalities of the CKD rats were reduced by YGY. Furthermore, decreased expression of HIF1α and EPO, and increased expression of p-EPOR (Tyr368), p-JAK2 (Tyr570) and p-STAT5 (Ser725) were observed in the kidney and the testis of the CKD rats. The YGY extract dramatically increased the expression of HIF1α and EPO, and decreased the expression of p-EPOR (Tyr368), p-JAK2 (Tyr570) and p-STAT5 (Ser725) to regulate key proteins in the HIF1α-STAT5 pathway of the kidney and testis. CONCLUSIONS YGY has obvious reversal effects on the abnormal symptoms of adenine-induced CKD and the abnormal symptoms of rats with hypothyroidism and male reproductive hypotension. Its mechanism is related to its ability to regulate the HIF1α-STAT5 pathway.

Abstract
In traditional Chinese medicine, the feces of flying squirrels have long been used to promote blood circulation and relieve bodily stasis. However, the excrement of flying squirrels may harbor zoonotic agents that could be hazardous to public health. To understand the occurrence of bacterial and parasitic infections in this species, we investigated selected zoonotic pathogens including Leptospira and Blastocystis in the urine and feces of flying squirrels in China. Urine and fecal samples from flying squirrels were collected from a family-owned flying squirrel farm located in Enshi County, Hubei Province in China. Leptospira and Blastocystis DNA was extracted from the urine and feces of flying squirrels, and used as targets for PCR amplification, using different specific primers. PCR amplification and DNA sequencing showed that 4.4% (3/69) of flying squirrels were positive for Leptospira, while 30.4% (21/69) of the animals were positive for Blastocystis. Notably, 1.4% (1/69) of flying squirrels were found to be co-infected with Leptospira and Blastocystis. Sequence analyses allowed for the detection of 3 Blastocystis subtypes (ST1, ST3 and ST13), and mixed infections of Blastocystis subtype 1 and subtype 3 were found in 4.4% (3/69) of flying squirrels. Phylogenetic analysis of the 16S ribosomal RNA gene (rrs2), the flagellin B gene (flaB), and outer membrane lipoprotein lipL32 gene (LipL32) sequences indicated that the Leptospira species detected in the study was L. interrogans. We concluded that flying squirrels from central China were infected with Leptospira and Blastocystis, suggesting that these animals can be a source of infection for their owners, and using fresh excrement from this animal as traditional medicine could be risky to human health. To the best of our knowledge, this is the first report of Leptospira and Blastocystis infection in flying squirrels from Enshi County, China. Our findings provide new data on the epidemiology of these pathogens in this region.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE You-Gui-Yin (YGY) is a traditional Chinese recipe used for reinforcing kidney essence which is recorded in Jingyue Quanshu written by Zhang Jingyue in Ming dynasty. According to traditional Chinese medicine theory, kidney essence is associated with brain and without sufficient kidney essence, cognitive impairment may occur. AIM OF THE STUDY In this study, we aimed to investigate the effect of YGY extract on cognitive impairment of chronic renal failure (CRF) mice and explore the mechanisms involved. MATERIALS AND METHODS Aqueous extract of YGY was prepared from crude drugs and was quality controlled by high-performance liquid chromatography (HPLC). CRF was induced by 0.2% adenine in mice and CRF mice were intragastrically administered with 1.5 g kg-1, 3.0 g kg-1, and 6.0 g kg-1 of YGY extract. Mice were identified with CRF by determining several biochemical and physiological indexes, including creatinine clearance rate, serum creatinine, serum urea nitrogen, serum Ca, serum P, serum Mg, body weight and body temperature. Morris water maze and novel object recognition tests were conducted for evaluation of cognitive function. In addition, changes of CaMKIIα/CREB/BDNF and EPO/EPOR pathways in hippocampus were examined by detecting the protein expressions of CaMKIIα, p-CaMKIIα (Thr286), CREB1, p-CREB1 (Ser133), BDNF, EPO, EPOR, p-EPOR (Tyr485), STAT5, and AKT1 using western blotting assays. Also, the primary EPO-producing cells in brain (i.e. astrocytes) and EPO expression regulator HIF-2α were checked by fluorescence microscopy and western blotting assay, respectively. RESULTS Nine components in YGY extract were figured out and monitored with their contents by HPLC for the quality control of YGY extract. Biochemical and physiological measurements validated the success of induction of CRF in mice, and YGY extract significantly retarded the CRF progression and ameliorated the CRF-induced cognitive impairment. The behavioral tests showed that compared with normal control mice, CRF mice had impaired cognitive function. However, treatment of YGY extract significantly ameliorated the cognitive impairment of CRF mice. Additionally, decreased expressions of hippocampal CaMKIIα, p-CaMKIIα (Thr286), CREB1, p-CREB1 (Ser133), and BDNF were observed in the hippocampus of CRF mice, but YGY extract significantly restored these protein expressions. Moreover, hippocampal EPO, EPOR, p-EPOR (Tyr485), STAT5, AKT1, and HIF-2α, as well as the number of astrocytes in CA1 zone of hippocampus were also decreased in CRF mice, while YGY extract prominently promoted the expressions of these proteins and increased the number of astrocytes. CONCLUSIONS All the data in this study suggested that YGY extract ameliorated the cognitive impairment of CRF mice, and this amelioration was related to up-regulating the CaMKIIα/CREB/BDNF and EPO/EPOR pathways.

Abstract
Atom probe tomography (APT) and scanning transmission electron microscopy (STEM) techniques were used to probe the long-time thermal stability of nm-scale Mn-Ni-Si precipitates (MNSPs) formed in intermediate and high Ni reactor pressure vessel steels under high fluence neutron irradiation at ≈320 °C. Post irradiation annealing (PIA) at 425 °C for up to 57 weeks was used to determine if the MNSPs are: (a) non-equilibrium solute clusters formed and sustained by radiation induced segregation (RIS); or, (b) equilibrium G or Γ2 phases, that precipitate at accelerated rates due to radiation enhanced diffusion (RED). Note the latter is consistent with both thermodynamic models and x-ray diffraction (XRD) measurements. Both the experimental and an independently calibrated cluster dynamics (CD) model results show that the stability of the MNSPs is very sensitive to the alloy Ni and, to a lesser extent, Mn content. Thus, a small fraction of the largest MNSPs in the high Ni steel persist, and begin to coarsen at long times. These results suggest that the MNSPs remain a stable phase, even at 105 °C higher than they formed at, thus are most certainly equilibrium phases at much lower service relevant temperatures of ≈290 °C.

Abstract
The aim of this paper was to observe the changes of EPO in rats with chronic renal failure and low immunity induced by adenine and to investigate the reversal effect of Yougui Yin(YGY)and exogenous EPO.SD rats were randomly divided into normal control group(n=20)and adenine-model group(n=90).The adenine-model group rats were given with adenine 150 mg·kg~(-1)for 14days by gavage administration,and then randomly divided into 8 groups as follows:model group(n=20),YGY groups(10,20,40 g·kg~(-1),10 in each group),rh EPO group(500,1 000,1 500 IU·kg~(-1),10 in each group),and Guilu Erxian Gao 10 g·kg~(-1)group(positive control group,n=10).From the 15th day,every group except normal control group received 150 mg·kg~(-1)adenine by gavage administration once every two days to maintain the model.Meanwhile,the rats in each YGY group and Guilu Erxian Gao group received corresponding drugs by gavage administration once a day for 30 days.The rats in rh EPO groups were subcutaneously injected with rh E-PO once every 3 days for 30 days.On day 46,rats were anesthetized to take blood and then sacrificed.The serum levels of creatinine,urea,glandular hormone,immunoglobulin,complement and interleukin,the proportion of T cells in the spleen,the killing rate of NKcells and the proliferative capacity of spleen cells were measured.Western blot was used to detect the key proteins in JAK2-STAT5 and NF-κB pathways mediated by EPO in kidney and spleen.As compared with the normal control group,the serum levels of CREA and UREA were increased significantly and the serum levels of ACTH,T and T3 were decreased significantly in the model group rats,indicating that the functions of kidney,adrenal gland,gonad and thyroid in rats were decreased.At the same time,the serum levels of Ig A,Ig G,Ig M,C3,C4,IL-2 and IL-6 were significantly decreased,the proportion of CD4~+,CD4~+/CD8~+T cell subsets,the killing rate of NK cell and the proliferation ability of spleen lymphocyte in spleen of the model group rats were significantly declined,indicating that the immune function of model group rats was decreased,and the model of kidney deficiency immunodeficiency was successfully constructed.As compared with the model group,both YGY and rh EPO significantly reduced serum levels of CREA and UREA,significantly increased serum levels of ACTH,T,T3,T4,Ig A,Ig G,Ig M,C3,C4,IL-2,and IL-6,increased the proportion of CD4~+,CD4~+/CD8~+T cell subsets,the killing rate of NK cell and the proliferation ability of spleen lymphocyte in spleen.YGY could significantly increase the content of EPO in serum.Both YGY and rh EPO could regulate the expression of EPOR,p-JAK2/JAK2,STAT5,NF-κB p50,NF-κB p65 and NF-κB IκB of EPO-mediated JAK2-STAT5 and NF-κB pathways in kidney and spleen.EPO is an important factor in the chronic renal failure and low immunity induced by adenine in rats.Exogenous EPO and YGY have significant reversal effects for the model rats.The mechanism of YGY may be related to the up-regulation of EPO in serum and regulating the expression of key proteins in EPO-mediated JAK2-STAT5 and NF-κB pathways in kidney and spleen.The mechanism of exogenous EPO may be related to regulating the expression of the key proteins in EPO-mediated JAK2-STAT5 and NF-κB pathways in kidney and spleen.

Abstract
The aim of the study was to validate a revised Mandarin version of the Postoperative Quality of Recovery Scale (PostopQRS) and to apply the revised version in a Chinese population. In a prospective design, bilingual volunteers completed the scale at baseline, day one, day seven, and day 14 in both languages, with the order of language and parallel forms randomised. In addition, lung cancer patients undergoing open or video-assisted thoracoscopic surgery (VATS) completed the Mandarin version prior to surgery, day one, day three, day seven, day 14, one month, and three months postoperatively. Sixty-eight volunteers participated in the validation part of the study and in the clinical application, 93 lung cancer patients were included. The scores in the Mandarin version were equal to the English version in all domains at all timepoints including the word generation task, when the Mandarin morpheme was included in any part of the Mandarin word. However, Mandarin scores were lower in the word generation task if the morpheme was only included in the first part of the word. In addition, the Mandarin version was able to identify lower rates of overall recovery (<i>P</i> <0.01), nociceptive (<i>P</i> <0.01), emotive (<i>P</i> <0.01), and activities of daily living recovery (<i>P</i>=0.02) after open surgery compared to after VATS. The revised Mandarin version is equivalent to the English version for the cognitive domain, if morpheme substitution for the word generation task is allowed as any part of the word, and it is able to discriminate quality of recovery in Chinese patients.

Abstract
Alveolar bone is a mechanosensitive tissue that provides structural support for teeth. Alveolar bone loss is common with aging, menopause, tooth loss, and periodontitis and can lead to additional tooth loss, reduced denture fixation, and challenges in placing dental implants. The current studies suggest that sclerostin and DKK1, which are established osteocyte-derived inhibitors of bone formation, contribute to alveolar bone loss associated with estrogen ablation and edentulism in rats. Estrogen-deficient ovariectomized rats showed significant mandibular bone loss that was reversed by systemic administration of sclerostin antibody (SAB) alone and in combination with DKK1 antibody (DAB). Osteocytes in the dentate and edentulous rat maxilla expressed Sost (sclerostin) and Dkk1 (DKK1) mRNA, and molar extraction appeared to acutely increase DKK1 expression. In a chronic rat maxillary molar extraction model, systemic SAB administration augmented the volume and height of atrophic alveolar ridges, effects that were enhanced by coadministering DAB. SAB and SAB+DAB also fully reversed bone loss that developed in the opposing mandible as a result of hypo-occlusion. In both treatment studies, alveolar bone augmentation with SAB or SAB+DAB was accompanied by increased bone mass in the postcranial skeleton. Jaw bone biomechanics showed that intact sclerostin-deficient mice exhibited stronger and denser mandibles as compared with wild-type controls. These studies show that sclerostin inhibition, with and without DKK1 coinhibition, augmented alveolar bone volume and architecture in rats with alveolar bone loss. These noninvasive approaches may have utility for the conservative augmentation of alveolar bone.

Abstract
Since the discovery of neural stem cells(NSCs) in embryonic and adult mammalian central nervous systems, new approaches for proliferation and differentiation of NSCs have been put forward. One of the approaches to promote the clinical application of NSCs is to search effective methods to regulate the proliferation and differentiation. This problem is urgently to be solved in the medical field. Previous studies have shown that traditional Chinese medicine could promote the proliferation and differentiation of NSCs by regulating the relevant signaling pathway in vivo and in vitro. Domestic and foreign literatures for regulating the proliferation and differentiation of neural stem cells in recent 10 years and the reports for their target and signaling pathways were analyzed in this paper. Traditional Chinese medicine could regulate the proliferation and differentiation of NSCs through signaling pathways of Notch, PI3K/Akt, Wnt/β-catenin and GFs. However, studies about NSCs and traditional Chinese medicine should be further deepened; the mechanism of multiple targets and the comprehensive regulation function of traditional Chinese medicine should be clarified.

Abstract
The functional role of respiratory microbiota has attracted an accumulating attention recently. However, the role of respiratory microbiome in lung carcinogenesis is mostly unknown. Our study aimed to characterize and compare bilateral lower airway microbiome of lung cancer patients with unilateral lobar masses and control subjects. Protected bronchial specimen brushing samples were collected from 24 lung cancer patients with unilateral lobar masses (paired samples from cancerous site and the contralateral noncancerous site) and 18 healthy controls undergoing bronchoscopies and further analyzed by 16S rRNA amplicon sequencing. As results, significant decreases in microbial diversity were observed in patients with lung cancer in comparison to the controls, alpha diversity steadily declined from healthy site to noncancerous to cancerous site. Genus Streptococcus was significantly more abundant in cancer cases than the controls, while Staphylococcus was more abundant in the controls. The area under the curve of genus Streptococcus used to predict lung cancer was 0.693 (sensitivity = 87.5%, specificity = 55.6%). The abundance of genus Streptococcus and Neisseria displayed an increasing trend whereas Staphylococcus and Dialister gradually declined from healthy to noncancerous to cancerous site. Collectively, lung cancer-associated microbiota profile is distinct from that found in healthy controls, and the altered cancer-associated microbiota is not restricted to tumor tissue. The genus Streptococcus was abundant in lung cancer patients and exhibited moderate classification potential. The gradual microbiota profile shift from healthy site to noncancerous to paired cancerous site suggested a change of the microenvironment associated with the development of lung cancer.

Abstract
UNLABELLED This study was to determine if antibody against sclerostin (Scl-Ab) could prevent glucocorticoid (GC)-induced osteoporosis in mice. We found that Scl-Ab prevented GC-induced reduction in bone mass and bone strength and that the anabolic effects of Scl-Ab might be partially achieved through the preservation of osteoblast activity through autophagy. INTRODUCTION Glucocorticoids (GCs) inhibit bone formation by altering osteoblast and osteocyte cell activity and lifespan. A monoclonal antibody against sclerostin, Scl-Ab, increased bone mass in both preclinical animal and clinical studies in subjects with low bone mass. The objectives of this study were to determine if treatment with the Scl-Ab could prevent loss of bone mass and strength in a mouse model of GC excess and to elucidate if Scl-Ab modulated bone cell activity through autophagy. METHODS We generated reporter mice that globally expressed dsRed fused to LC3, a protein marker for autophagosomes, and evaluated the dose-dependent effects of GCs (0, 0.8, 2.8, and 4 mg/kg/day) and Scl-Ab on autophagic osteoblasts, bone mass, and bone strength. RESULTS GC treatment at 2.8 and 4 mg/kg/day of methylprednisolone significantly lowered trabecular bone volume (Tb-BV/TV) at the lumbar vertebrae and distal femurs, cortical bone mass at the mid-shaft femur (FS), and cortical bone strength compared to placebo (PL). In mice treated with GC and Scl-Ab, Tb-BV/TV increased by 60-125 %, apparent bone strength of the lumbar vertebrae by 30-70 %, FS-BV by 10-18 %, and FS-apparent strength by 13-15 %, as compared to GC vehicle-treated mice. GC treatment at 4 mg/kg/day reduced the number of autophagic osteoblasts by 70 % on the vertebral trabecular bone surface compared to the placebo group (PL, GC 0 mg), and GC + Scl-Ab treatment. CONCLUSIONS Treatment with Scl-Ab prevented GC-induced reduction in both trabecular and cortical bone mass and strength and appeared to maintain osteoblast activity through autophagy.

Abstract
The codon usage patterns of open reading frames (ORFs) in cyprinid herpesvirus 3 (CyHV-3) have been investigated in this study. The high correlation between GC12 % and GC3 % suggests that mutational pressure rather than natural selection is the main factor that determines the codon usage and base component in the CyHV-3, while mutational pressure effect results from the high correlation between GC3 % and the first principal axis of principle component analysis (Axis 1) on the relative synonymous codon usage (RSCU) value of the viral functional genes. However, the interaction between the absolute codon usage bias and GC3 % suggests that other selections take part in the formation of codon usage, except for the mutational pressure. It is noted that the similarity degree of codon usage between the CyHV-3 and goldfish, Carassius auratus (L.), is higher than that between the virus and common carp, Cyprinus carpio L., suggesting that the goldfish plays a more important role than the common carp in codon usage pattern of the CyHV-3. The study of codon usage in CyHV-3 can provide some evidence about the molecular evolution of the virus. It can also enrich our understanding about the relationship between the CyHV-3 and its hosts by analysing their codon usage patterns.

Abstract
The expansion of a municipal solid waste (MSW) landfill requires the ability to predict settlement behavior of the existing landfill. The practice of using a single compressibility value when performing a settlement analysis may lead to inaccurate predictions. This paper gives consideration to changes in the mechanical compressibility of MSW as a function of the fill age of MSW as well as the embedding depth of MSW. Borehole samples representative of various fill ages were obtained from five boreholes drilled to the bottom of the Qizhishan landfill in Suzhou, China. Thirty-one borehole samples were used to perform confined compression tests. Waste composition and volume-mass properties (i.e., unit weight, void ratio, and water content) were measured on all the samples. The test results showed that the compressible components of the MSW (i.e., organics, plastics, paper, wood and textiles) decreased with an increase in the fill age. The in situ void ratio of the MSW was shown to decrease with depth into the landfill. The compression index, Cc, was observed to decrease from 1.0 to 0.3 with depth into the landfill. Settlement analyses were performed on the existing landfill, demonstrating that the variation of MSW compressibility with fill age or depth should be taken into account in the settlement prediction.

Abstract
Mesenchymal stem cells (MSCs) have received considerable attention in recent years. Particularly exciting is the prospect that MSCs could be differentiated into specialized cells of interest, which could then be used for cell therapy and tissue engineering. MSCs derived from nonhuman primates could be a powerful tool for investigating the differentiation potential in vitro and in vivo for preclinical research. The purpose of this study was to isolate cynomolgus mesenchymal stem cells (cMSCs) from adult bone marrow and characterize their growth properties and multipotency. Mononuclear cells were isolated from cynomolgus monkey bone marrow by density-gradient centrifugation, and adherent fibroblast-like cells grew well in the complete growth medium with 10 microM Tenofovir. cMSCs expressed mesenchymal markers, such as CD29, CD105, CD166 and were negative for hematopoietic markers such as CD34, CD45. Furthermore, the cells were capable of differentiating into osteogenic, chondrogenic, and adipogenic lineages under certain conditions, maintaining normal karyotype throughout extended culture. We also compared different methods (lipofection, nucleofection and lentivirus) for genetic modification of cMSCs and found lentivirus proved to be the most effective method with transduction efficiency of up to 44.6% and lowest level of cell death. The cells after transduction stably expressed green fluorescence protein (GFP) and maintained the abilities to differentiate down osteogenic and adipogenic lineages. In conclusion, these data showed that cMSCs isolated from cynomolgus bone marrow shared similar characteristics with human MSCs and might provide an attractive cell type for cell-based therapy in higher-order mammalian species disorder models.

Abstract
Dentin Matrix Protein 1 (DMP1) is highly expressed in alveolar bone and cementum, which are important components of the periodontium. Therefore, we hypothesized that Dmp1 is critical for the integrity of the periodontium, and that deletion may lead to increased susceptibility to disease. An early-onset periodontal defect was observed in the Dmp1 null mouse, a mouse model of hypophosphatemic rickets. The alveolar bone is porous, with increased proteoglycan expression. The cementum is also defective, as characterized by irregular, punctate fluorochrome labeling and elevated proteoglycan. The osteocyte and cementocyte lacuno-canalicular system of both alveolar bone and cementum is abnormal, with irregular lacunar walls and fewer canaliculi. As a consequence, there is significant interproximal alveolar bone loss, combined with detachment between the periodontal ligament (PDL) and cementum. We propose that defective alveolar bone and cementum may account for the periodontal breakdown and increased susceptibility to bacterial infection in Dmp1 null mice.

Abstract
Mesenchymal stem cells (MSCs) are multipotent stem cells capable of differentiating into adipocytes in the presence of a hormone cocktail. These cells thus provide a promising model for studying the early events of adipogenesis. Here, we examine the involvement of the PI3K/Akt and mTOR/p70S6K signaling pathways in human MSC adipogenesis. We found that the two pathways were strongly activated with a similar temporal profile under the adipogenesis-inducing hormone cocktail and this activation could be blocked by LY294002, a specific inhibitor of PI3K. Furthermore, rapamycin, a specific inhibitor of mTOR, blocked the activation of mTOR/p70S6K but not PI3K/Akt. Both LY294002 and rapamycin severely suppressed lipid accumulation, as well as the expression of adipogenic markers, including PPAR gamma 2 and C/EBP alpha, two master adipogenic transcription factors. Together, these data indicate that the mTOR/p70S6K pathway acts downstream of the PI3K/Akt pathway in mediating the adipogenic conversion of MSCs. In conclusion, our data suggest that the PI3K/Akt and mTOR/p70S6K signaling pathways are essential for adipogenesis of human MSCs.

Abstract
The rhesus macaque (Macaca mulatta) is an abundant primate species that diverged from the ancestors of Homo sapiens about 25 million years ago. Because they are genetically and physiologically similar to humans, rhesus monkeys are the most widely used nonhuman primate in basic and applied biomedical research. We determined the genome sequence of an Indian-origin Macaca mulatta female and compared the data with chimpanzees and humans to reveal the structure of ancestral primate genomes and to identify evidence for positive selection and lineage-specific expansions and contractions of gene families. A comparison of sequences from individual animals was used to investigate their underlying genetic diversity. The complete description of the macaque genome blueprint enhances the utility of this animal model for biomedical research and improves our understanding of the basic biology of the species.

Abstract
A new procedure for combining direct methods with the solvent-flattening technique is proposed for phasing single isomorphous replacement (SIR) or one-wavelength anomalous scattering (OAS) data of proteins. The new procedure differs from the previous one [Zheng, Zheng, Gu, Mo, Fan & Hao (1997). Acta Cryst. D53, 49-55] in that the direct method not only provides input phases to but also accepts feedback phases from solvent flattening, thus forming an iterative process for breaking the ambiguities and refining the values of phases. The new procedure was tested with the experimental SIR data of the known structure ribonuclease Sa. For the strongest 1000 of the total 7264 reflections, the mean F(obs)-weighted phase error is 7.5 and 9.4 degrees lower than that of the previous procedure and that of solvent flattening alone, respectively.

Abstract
Phosphodiesterases (PDEs) control cellular concentrations of cyclic adenosine monophosphate (cAMP) or cyclic guanosine monophosphate (cGMP). PDE4 and PDE5 selectively hydrolyze cAMP and cGMP, respectively. PDE family members share approximately 25% sequence identity within a conserved catalytic domain of about 300 amino acids. Crystal structure analysis of PDE4's catalytic domain identifies two metal-binding sites: a high-affinity site and a low-affinity site, which probably bind zinc (Zn2+) and magnesium (Mg2+), respectively. Absolute conservation among the PDEs of two histidine and two aspartic acid residues for divalent metal binding suggests the importance of these amino acids in catalysis. Although active sites of PDEs are apparently structurally similar, PDE4 is specifically inhibited by selective inhibitors such as rolipram, while PDE5 is preferentially blocked by sildenafil. Modeling interactions of the PDE5 inhibitor sildenafil with the PDE4 active site may help explain inhibitor selectivity and provide useful information for the design of new inhibitors.

Abstract
To identify amino acid residues involved in PDE3-selective inhibitor binding, we selected eight presumed interacting residues in the substrate-binding pocket of PDE3A using a model created on basis of homology to the PDE4B crystal structure. We changed the residues to alanine using site-directed mutagenesis technique, expressed the mutants in a baculovirus/Sf9 cell system, and analyzed the kinetic characteristics of inhibition of the mutant enzymes by milrinone and cilostazol, specific inhibitors of PDE3. The mutants displayed differential sensitivity to the inhibitors. Mutants Y751A, D950A, and F1004A had reduced sensitivity to milrinone (K(i) changed from 0.66 microM for the recombinant PDE3A to 7.5 to 156 microM for the mutants), and diminished sensitivity to cilostazol (K(i) of the mutants were 18- to 371-fold higher than that of the recombinant PDE3A). In contrast, the mutants T844A, F972A and Q975A showed increased K(i) for cilostazol but no difference for milrinone from the recombinant PDE3A. Molecular models show that the PDE3 inhibitors cilostazol and milrinone share some of common residues but interact with distinct residues at the active site, suggesting that selective inhibitors can be designed with flexible size against PDE3 active site. Our study implies that highly conserved residuals Y751, D950 and F1004 in the PDE families are key residues for binding of both substrate and inhibitors, and nonconserved T844 may be responsible for the cilostazol selectivity of PDE3A. Detailed knowledge of the structure of inhibitory sites should contribute to development of more potent and specific inhibitory drugs.
