Abstract
Fatty liver disease (FLD) is one of the major causes of chronic liver disease worldwide. With the increasing incidence of obesity and metabolic syndrome worldwide, FLD concomitant with other liver diseases is becoming more common, and multiple etiological overlap is associated with poor disease prognosis. Therefore, FLD concomitant with other liver diseases is a clinical concerning issue. Non-alcoholic fatty liver disease (NAFLD) encompasses a spectrum of disease continuum from non-alcoholic fatty liver (NAFL) to non-alcoholic steatohepatitis (NASH), and relative end stage liver disease, excluding other factors that may lead to fatty liver disease such as excessive alcohol consumption et. al. Following the nomenclature of NAFLD with metabolic associated fatty liver disease (MAFLD), an international panel of experts proposed a new name in June 2023 as Metabolic dysfunction - associated steatotic liver disease (MASLD), replacing the word "fatty" with "steatotic," The effect of lipid toxicity on FLD progression was highlighted. Compared with the concept of MAFLD, the disease spectrum of MASLD is broader, and the etiology and mechanism are more clear. The nomenclature of FLD brings some influence to the diagnosis and treatment of chronic liver diseases concomitant with FLD, including chronic hepatitis B, alcoholic fatty liver disease and genetic metabolic diseases. This article reviews the influence of renaming FLD on the diagnosis and treatment of FLD concomitant with other etiologies caused liver diseases.

Abstract
Objective: To compare the clinical and pathological features of children with chronic viral hepatitis B combined with metabolic-associated fatty liver disease (CHB-MAFLD) and chronic viral hepatitis B alone (CHB alone), and to further explore the effect of MAFLD on the progression of hepatic fibrosis in CHB. Methods: 701 initially treated CHB children confirmed by liver biopsy admitted to the Fifth Medical Center of the PLA General Hospital from January 2010 to December 2021 were collected continuously. They were divided into CHB-MAFLD and CHB-alone groups according to whether they were combined with MAFLD. A retrospective case-control study was conducted. CHB-MAFLD was used as the case group, and 1:2 propensity score matching was performed with the CHB alone group according to age and gender, including 56 cases in the CHB-MAFLD group and 112 cases in the CHB alone group. The body mass index (BMI), metabolic complications, laboratory indicators, and pathological characteristics of liver tissue were compared between the two groups. The related factors affecting liver disease progression in CHB were analyzed by a binary logistic regression model. The measurement data between groups were compared using the t-test and rank sum test. The χ (2) test was used for the comparison of categorical data between groups. Results: Alanine aminotransferase (ALT, P = 0.032) and aspartate aminotransferase (AST, P = 0.003) levels were lower in the CHB-MAFLD group than those in the CHB alone group, while BMI (P < 0.001), triglyceride (TG, P < 0.001), total cholesterol (P = 0.016) and the incidence of metabolic syndrome (P < 0.001) were higher in the CHB alone group. There were no statistically significant differences in HBsAg quantification or HBV DNA load between the two groups (P > 0.05). Histologically, the proportion of significant liver fibrosis (S2-S4) was higher in the CHB-MAFLD group than that in the CHB alone group (67.9% vs. 49.1%, χ (2) = 5.311, P = 0.021). Multivariate regression results showed that BMI (OR = 1.258, 95% CI: 1.145 ~ 1.381, P = 0.001) and TG (OR = 12.334, 95% CI: 3.973 ~ 38.286, P < 0.001) were the risk factors for hepatic steatosis occurrence in children with CHB. MAFLD (OR = 4.104, 95% CI: 1.703 ~ 9.889, P = 0.002), liver inflammation (OR = 3.557, 95% CI: 1.553 ~ 8.144, P = 0.003), and γ-glutamyl transferase (OR = 1.019, 95% CI: 1.001 to 1.038, P = 0.038) were independent risk factors for significant hepatic fibrosis in children with CH. Conclusion: MAFLD occurrence is related to metabolic factors in children with CHB. Additionally, the combination of MAFLD may promote liver fibrosis progression in CHB patients.

Abstract
Objective: To explore carnosine dipeptidase 1 (CNDP1) potential value as a diagnostic and prognostic evaluator of hepatocellular carcinoma (HCC). Methods: A gene chip and GO analysis were used to screen the candidate marker molecule CNDP1 for HCC diagnosis. 125 cases of HCC cancer tissues, 85 cases of paracancerous tissues, 125 cases of liver cirrhosis tissues, 32 cases of relatively normal liver tissue at the extreme end of hepatic hemangioma, 66 cases from serum samples of HCC, and 82 cases of non-HCC were collected. Real-time fluorescent quantitative PCR, immunohistochemistry, western blot, and enzyme-linked immunosorbent assay were used to detect the differences in mRNA and protein expression levels of CNDP1 in HCC tissue and serum. Receiver operating characteristic (ROC) curves and Kaplan-Meier survival were used to analyze and evaluate the value of CNDP1 in the diagnosis and prognosis of HCC patients. Results: The expression level of CNDP1 was significantly reduced in HCC cancer tissues. The levels of CNDP1 were significantly lower in the cancer tissues and serum of HCC patients than those in liver cirrhosis patients and normal controls. ROC curve analysis showed that the area under the curve of serum CNDP1 in the diagnosis of HCC patients was 0.753 2 (95% CI 0.676-0.830 5), and the sensitivity and specificity were 78.79% and 62.5%, respectively. The combined detection of serum CNDP1 and serum alpha-fetoprotein (AFP) significantly improved the diagnostic accuracy (AUC = 0.820 6, 95% CI 0.753 5-0.887 8). The diagnostic sensitivity and specificity of serum CNDP1 for AFP-negative HCC patients were 73.68% and 68.75% (AUC = 0.793 1, 95% CI 0.708 8-0.877 4), respectively. In addition, the level of serum CNDP1 distinguished small liver cancer (tumor diameter < 3 cm) (AUC = 0.757 1, 95% CI 0.637 4-0.876 8). Kaplan-Meier survival analysis showed that CNDP1 was associated with a poor prognosis in HCC patients. Conclusion: CNDP1 may be a potential biomarker for the diagnostic and prognostic evaluation of HCC, and it has certain complementarity with serum AFP.

Abstract
Hepatitis type E virus (HEV) is one of the main causes of acute hepatitis globally and has thus gained attention as a public health issue. The diverse clinical manifestations of hepatitis type E are typically acute and self-limiting with mild symptoms, but populations with underlying liver disease or immunocompromised patients can have severe and chronic symptoms. Severity and chronicity can arise and manifest as fulminant hepatitis, chronic hepatitis, or even hepatic failure. HEV infection-induced hepatic failure (acute-on-chronic liver failure), based on the different backgrounds of chronic liver disease, is a clinical phenotype of severe HEV infection that requires attention. In addition, HEV infection can exhibit extrahepatic clinical manifestations of multi-system and organ involvement like neurological diseases (Guillain-Barré syndrome), renal diseases (membranous/membranous proliferative glomerulonephritis, cryoglobulinemia), and blood diseases (thrombocytopenia). At home or abroad, there are no antiviral drugs approved, particularly for HE treatment. Since most acute HE can resolve spontaneously, no special treatment is required clinically. However, in patients with severe or chronic HE, ribavirin (RBV) monotherapy and/or pegylated interferon-combination therapy have achieved certain antiviral effects. Combined small-molecule drugs and RBV have been attempted to treat HEV, but high-level evidence-based treatment is still lacking. Thus, new, highly effective anti-HEV drugs are clinical priorities to address these concerns. Severe and chronic HEV infections' clinical phenotype, early detection, mechanism, intervention, and outcome need additional study.

Abstract
Liver histological assessment is of great clinical significance for the diagnosis, classification, and prognosis prediction of drug-induced liver injury (DILI). Liver histological evaluation can effectively supplement RUCAM. The clinical phenotypes of DILI are complex and diverse, including acute, chronic and severe hepatic injury. DILI has multiple insult-targets, including hepatocytes, cholangiocytes, and vascular endothelial cells and others. The pathological damage patterns are similar to many types of non-DILI liver diseases, therefore making differential diagnosis difficult. New anti-tumor drugs such as immune checkpoints inhibitors and targeted therapy are widely used in clinical antineoplastic practice, thus the growing incidence of related liver injury occurs. Liver histological examination can effectively assess the pathological phenotypes and severity of DILI, so as to guide treatment. In uncommon conditions such as special types of DILI (such as hepatic vascular disease), DILI with other competitive etiology overlapping, chronic DILI, and DILI induced liver failure, liver histological assessment can provide strong support for identifying the cause, rational treatment, and prognosis. Currently, the histological evaluation system for drug-induced liver injury seems to be a lack of consensus, and the diagnosis of DILI is short of highly specific and sensitive serological markers. All in all, liver histological assessment plays a crucial role in the diagnosis and differential diagnosis of DILI.

Abstract
Hepatocellular carcinoma (HCC) has a high incidence and low five-year survival rate in China. There is a lack of effective therapeutic approaches available for unresectable patients with advanced HCC. Recently, the development of targeted and immunotherapy agents and their application in the therapy of various solid tumors have brought new options and benefits to patients with advanced HCC. Companion diagnostics (CDx) emerged with the development of targeted agents, and its roles in selecting eligible patients for specific targeted/immunotherapy agents and improving prognosis are getting more prominent. This article focuses on the CDx technologies and applications related to HCC targeting and immunotherapy, in order to provide inspiration for the precise diagnosis and treatment of HCC.

Abstract
Cochliobolus lunatus (anamorph: Curvularia lunata) is a major pathogenic fungus that causes the Curvularia leaf spot of maize. ClMAT1-1-1 and ClMAT1-2-1, the C. lunatus orthologs of C. heterostrophus ChMAT1-1-1 and ChMAT1-2-1, were investigated in the present study to uncover their functions in C. lunatus. Southern blot analysis showed that these mating-type MAT genes exist in the C. lunatus genome as a single copy. ClMAT1-1-1 and ClMAT1-2-1 were knocked out and complemented to generate ΔClmat1-1-1 and ΔClmat1-2-1 and ΔClmat1-1-1-C and ΔClmat1-2-1-C, respectively. The mutant strains had defective sexual development and failed to produce pseudothecia. There were no significant differences in growth rate or conidia production between the mutant and wild-type strains. However, the aerial mycelia and mycelial dry weight of ΔClmat1-1-1 and ΔClmat1-2-1 were lower than those of wild type, suggesting that MAT genes affect asexual development. ClMAT genes were involved in the responses to cell wall integrity and osmotic adaptation. ΔClmat1-2-1 had a lower conidial germination rate than the wild-type strain CX-3. The virulence of ΔClmat1-2-1 and ΔClmat1-1-1 was also reduced compared with the wild-type. Complementary strains could restore all the phenotypes.

Abstract
OBJECTIVE To explore whether acupuncture combined with moxibustion could inhibit epithelialmesenchymal transition in Crohn's disease by affecting the transforming growth factor β 1 (TGF- β 1)/Smad3/Snail pathway. METHODS Sixty-three patients with Crohn's disease were randomly divided into an observation group (31 cases) receiving moxibustion at 43 °C combined with acupuncture, and a control group (32 cases) receiving moxibustion at 37 °C combined with sham acupuncture using a random number table. Patients were treated for 12 weeks. Crohn's Disease Activity Index (CDAI) was used to evaluate disease activity. Hematoxylin-eosin staining and transmission electron microscopy were utilized to observe the morphological and ultrastructural changes. Immunohistochemistry was used to detect the expression of transforming growth factor β 1 (TGF-β 1), T β R1, T β R2, Smad3, Snail, E-cadherin and fibronectin in intestinal mucosal tissues. RESULTS The decrease of the CDAI score, morphological and ultrastructural changes were more significant in observation group. The expression levels of TGF- β 1, Tβ R2, Smad3, and Snail in the observation group were significantly lower than those before the treatment (P<0.05 or P<0.01). After treatment, the expression levels of TGF-β 1, TβR2, and Snail in the observation group were significantly lower than those in the control group (all P<0.05); compared with the control group, the expression of fibronectin in the observation group was significantly decreased, and the expression of E-cadherin was significantly increased (all P<0.05). CONCLUSIONS Moxibustion at 43 °C combined with acupuncture may suppress TGF-β 1/Smad3/Snail pathway-mediated epithelial-mesenchymal transition of intestinal epithelial cells in Crohn's disease patients by inhibiting the expression levels of TGF-β 1, Tβ R2, Smad3, and Snail.

Abstract
OBJECTIVE To observe the effect of herb-partitioned moxibustion (HPM) on the miRNA expression profile of thyroid tissue in experimental autoimmune thyroiditis (EAT) rats. METHODS Rats were randomly divided into normal control (NC) group, EAT model (EAT) group, HPM group and western medicine (Med) group. EAT model rats were prepared by a combined immunization with complete and incomplete Freund's adjuvant emulsified with porcine thyroglobulin and iodine. Rats in the HPM group were treated with HPM, while rats in the Med group were treated with levothyrocine (1 μg/2 mL) by gavage. HE staining was used to observe the pathological morphological changes of thyroid tissue, ELISAs was uaed to detect the serum concentrations of TGAb, TPOAb, FT3, FT4, TSH. We then performed high-throughput miRNA sequencing to analyse the miRNA expression profiles in the thyroid tissues, followed by a bioinformatics analysis. RT-qPCR was used to verify the identified differentially expressed miRNAs. RESULTS HPM improved the thyroid tissue morphology and reduced serum TPOAb, TGAb, TSH concentration in EAT rats (P < 0.05), but with no obvious effect on FT3 and FT4 concentration. While the TSH, FT3 and FT4 concentration was significantly changed in the Med group (P < 0.01 or P < 0.05) compared with that of EAT group. Sequencing results showed that a total of 17 miRNAs were upregulated, and 4 were downregulated in the EAT rats, in which the expression levels of miR-346 and miR-331-5p were reversed by HPM. The target genes of the miRNAs that regulated by HPM were associated with a variety of immune factors and immune signals. RT-qPCR verification showed that the expression of miRNA-346 and miRNA-331-5p was consistent with the sequencing results. CONCLUSIONS HPM could regulate the the expression of miRNA-346 and miRNA-331-5p, then act on their target genes to immune and inflammation-related pathways, which may be one of the mechanisms of HPM on EAT rats.

Abstract
Abstract Objective To study the accuracy of Nolla method for age estimation of Northern Chinese Han children aged between 5.00 and 14.99 years based on original transformation tables and multiple regression model. Methods A total of 2 000 orthopantomographs (OPGs) were collected from the Hospital of Stomatology, Xi'an Jiaotong University, including 1 000 males and 1 000 females. Development stage of 7 left mandibular permanent teeth (except third molars) was assessed based on Nolla method, then age estimation was conducted through transformation tables and multiple regression model, respectively. Firstly, the development stage results of 7 permanent teeth were added up and the estimated age was obtained through the original transformation tables. Secondly, 80% of the samples (80 males and 80 females in each age group) were randomly selected from 2 000 OPGs as the train set. The chronological age of the selected patients was taken as the dependent variable, while gender and the development stage results of 7 permanent teeth were taken as the independent variable to establish multiple regression model. The remaining 20% of the samples were substituted into the model as the test set, to verify the accuracy of age estimation by multiple regression model. Results Mean chronological ages of males and females were 10.03±0.09 years and 10.01±0.09 years, respectively. The age estimated by original transformation tables showed an overestimation for males (0.18 years on average) and an underestimation for females (0.02 years on average), with mean absolute error (MAE) of 0.94 years and 0.97 years, respectively. While the results by multiple regression model showed that males were overestimated by 0.06 years on average and females were underestimated by 0.02 years on average. The MAE was 0.66 years and 0.77 years, respectively. Conclusion The Nolla method is suitable for age estimation of Northern Chinese Han children. Compared with the original transformation tables method, the multiple regression model is more accurate for age estimation.

Abstract
Abstract Facial reconstruction is a way to recover facial morphology by restoring soft tissues based on unidentified skulls using the knowledge of anatomy, anthropology, aesthetics, and computer science. It is applied in forensic science, oral plastic surgery and archeology, and especially plays an important role in the identification of the origin of the unknown corpses in forensic science. Facial reconstruction is the supplementary means of identification when other approaches (such as DNA comparison, imaging matching, dental records comparison, etc.) cannot identify individual identity. Facial soft tissue thickness (FSTT) is the basis of facial reconstruction and with the development of imaging and computer science, the techniques for measuring FSTT are improving rapidly and many related researches have appeared. This paper summarizes the application of facial reconstruction in forensic science, the accuracy of different methods and the research progress of this field to provide reference to this field.

Abstract
Objective: To compare the difference of soft and hard tissue changes between immediate implant and early implant placement in maxillary anterior region, so as to provide the basis for the selection of implant timing and surgical method for patients in clinical maxillary anterior dental esthetic zone. Methods: From January 2016 to January 2019, 89 patients [48 males and 41 females, aged (38.0±13.3) years] with dentition defect and single tooth implant restoration in the Department of Oral Implantology, Dalian Stomatological Hospital were retrospectively collected. The patients were divided into three groups according to different implant timing and operation methods: immediate implant flapless group (26 cases), immediate implant flap group (30 cases) and early implant group (33 cases, early implant 4-8 weeks after tooth extraction). The operation time, intraoperative and postoperative complications were compared among the three groups. Cone-beam CT was taken before operation, immediately after operation and 6 months after operation. The bone plate thickness immediately after implantation, bone plate thickness at 6 months after operation and absorption amount of bone plate thickness at labial side (immediately after operation minus 6 months after operation) were measured, and the absorption rate of labial bone plate was calculated. Three dimensional quantitative analysis was performed on the lip bone increment, residual bone volume (6 months after operation minus preoperative), and bone volume absorption rate of the three groups immediately after operation by using GuideMia, PlastyCAD and Geomagic engineering software. The pink and white esthetic indexes of the three groups were evaluated at 9 months and 15 months after implant placement. The implant stability quotient (ISQ) value was measured at 6 months after implantation, and the patients' satisfaction with the whole treatment process was investigated at 6 months after implantation. Results: The operation time of immediate implant flapless group was the shortest, the median (lower quartile, upper quartile) was 36.5 (33.3, 38.5) min. At 9 months after operation, PES was relatively high [8.5 (8.0, 9.0)], and the final patient satisfaction was 8.0 (7.3, 8.8), and the difference was statistically significant compared with the other two groups (P<0.05). There was no significant difference in the incidence of intraoperative and postoperative complications among the groups (P>0.05). At 6 months after operation, the thickness of labial bone plate in early group was 3.09 (3.00, 3.25) mm, which was greater than that in the immediate non flap group [1.90 (1.72, 2.33) mm] and that in the immediate implant flap group [2.39 (2.05, 3.06) mm], and the difference was statistically significant (P<0.05). The absorption of labial bone thickness in immediate implant flapless group [0.61 (0.35, 0.98) mm] was significantly lower than that in the immediate implant flap group [1.13 (0.97, 1.53) mm] and that in the early implant group [1.23 (1.07, 1.37) mm] (P<0.05). After 6 months, the residual bone volume of immediate flapless group was 38.7 (31.2, 54.6) mm3 and was significantly different from that in early implant group [109.1 (85.6, 263.1) mm3] (P<0.05), and there was no significant difference in the residual bone volume between immediate implant flapless group and immediate implant flap group (P>0.05). Conclusions: Immediate implant can reduce the treatment time with equal esthetic outcome of implant supported restoration of anterior teeth, and patients prefer it more. The bone volume of lip side was not significantly increased after immediate flap operation, and the bone absorption was less after immediate flap operation. Early implant placement can better maintain the three-dimensional bone mass, and the three groups can obtain good clinical results in the short term, but the long-term effect needs further follow-up study.

Abstract
BACKGROUND Autophagy is an evolutionarily conserved biological process in eukaryotic cells that involves lysosomal-mediated degradation and recycling of related cellular components. Recent studies have shown that autophagy plays an important role in the pathogenesis of Crohn’s disease (CD). Herbal cake-partitioned moxibustion (HM) has been historically practiced to treat CD. However, the mechanism by which HM regulates colonic autophagy in CD remains unclear.
AIM To observe whether HM can alleviate CD by regulating colonic autophagy and to elucidate the underlying mechanism.
METHODS Rats were randomly divided into a normal control (NC) group, a CD group, an HM group, an insulin + CD (I + CD) group, an insulin + HM (I + HM) group, a rapamycin + CD (RA + CD) group, and a rapamycin + HM (RA + HM) group. 2,4,6-trinitrobenzenesulfonic acid was administered to establish a CD model. The morphology of the colonic mucosa was observed by hematoxylin-eosin staining, and the formation of autophagosomes was observed by electron microscopy. The expression of autophagy marker microtubule-associated protein 1 light chain 3 beta (LC3B) was observed by immunofluorescence staining. Insulin and rapamycin were used to inhibit and activate colonic autophagy, respectively. The mRNA expression levels of phosphatidylinositol 3-kinase class I (PI3KC1), Akt1, LC3B, sequestosome 1 (p62), and mammalian target of rapamycin (mTOR) were evaluated by RT-qPCR. The protein expression levels of interleukin 18 (IL-18), tumor necrosis factor-α (TNF-α), nuclear factor κB/p65 (NF-κB p65), LC3B, p62, coiled-coil myosin-like BCL2-interacting protein (Beclin-1), p-mTOR, PI3KC1, class III phosphatidylinositol 3-kinase (PI3KC3/Vps34), and p-Akt were evaluated by Western blot analysis.
RESULTS Compared with the NC group, the CD group showed severe damage to colon tissues and higher expression levels of IL-18 and NF-κB p65 in colon tissues (P < 0.01 for both). Compared with the CD group, the HM group showed significantly lower levels of these proteins (PIL-18 < 0.01 and Pp65 < 0.05). There were no significant differences in the expression of TNF-α protein in colon tissue among the rat groups. Typical autophagic vesicles were found in both the CD and HM groups. The expression of the autophagy proteins LC3B and Beclin-1 was upregulated (P < 0.01 for both) in the colon tissues of rats in the CD group compared with the NC group, while the protein expression of p62 and p-mTOR was downregulated (P < 0.01 for both). However, these expression trends were significantly reversed in the HM group compared with the CD group (PLC3B < 0.01, PBeclin-1 < 0.05, Pp62 < 0.05, and Pm-TOR < 0.05). Compared with those in the RA + CD group, the mRNA expression levels of PI3KC1, Akt1, mTOR, and p62 in the RA + HM group were significantly higher (PPI3KC1 < 0.01 and PAkt1, mTOR, and p62 < 0.05), while those of LC3B were significantly lower (P < 0.05). Compared with the RA + CD group, the RA + HM group exhibited significantly higher PI3KC1, p-Akt1, and p-mTOR protein levels (PPI3KC1 < 0.01, Pp-Akt1 < 0.05, and Pp-mTOR < 0.01), a higher p62 protein level (P = 0.057), and significantly lower LC3B and Vps34 protein levels (P < 0.01 for both) in colon tissue.
CONCLUSION HM can activate PI3KC1/Akt1/mTOR signaling while inhibiting the PI3KC3 (Vps34)-Beclin-1 protein complex in the colon tissues of CD rats, thereby inhibiting overactivated autophagy and thus exerting a therapeutic effect.

Abstract
BACKGROUND Ulcerative colitis (UC), also known as chronic nonspecific UC, is an inflammatory bowel disease characterized by diffuse colonic mucosal inflammation. The incidence and prevalence of UC have risen markedly, and the disease seriously affects the quality of life of patients, and poses a great burden on the world health care infrastructure and economy. CASE SUMMARY We present a 60-year-old man who had ulcerative colitis for more than 10 years, with recurrent abdominal pain, bloody diarrhea with mucopurulent stool. The treatments with sulfasalazine, mesalazine, and traditional Chinese medicine were not effective, and herbs-partitioned moxibustion (HPM) was then applied at "Zhongwan" (RN12), "Tianshu"(ST25), and "Qihai" (RN6) once a day for about 30 min, 3 times per week, for 6 mo.His main clinical symptoms of abdominal pain, bloody diarrhea with mucopurulent stool gradually improved, and the mucosa had nearly healed, as observed under endoscopy by the 6th mo. The patient's condition was alleviated without relapsing during the subsequent 3-mo follow-up period. HPM showed a significant effect in the treatment of ulcerative colitis in this case, and the effect would help the patient to maintain remission for at least 3 mo. CONCLUSION A series of symptoms of this UC patient significantly improved with the treatment of HPM.

Abstract
BACKGROUND A20 inhibits intestinal epithelial cell apoptosis in Crohn’s disease, and herbs-partitioned moxibustion (HPM) has been demonstrated to be an effective treatment for Crohn’s disease. However, the mechanism by which HPM reduces intestinal epithelial cell apoptosis in Crohn’s disease has not been thoroughly elucidated to date.
AIM To elucidate whether HPM exerts its effects by upregulating A20 to affect intestinal epithelial cell apoptosis in a Crohn’s disease mouse model.
METHODS In this study, mice with A20 deletion in intestinal epithelial cells (A20IEC-KO) were utilized to establish a Crohn’s disease mouse model with 2,4,6-trinitrobenzene sulfonic acid (TNBS) administration, as well as wild-type mice. Mice were randomly divided into normal control (NC), model control (MC), mesalazine (MESA), and HPM groups. The morphology of the colonic mucosa was observed by hematoxylin-eosin staining, and serum endotoxin and apoptosis of epithelial cells were evaluated by enzyme-linked immunosorbent assay and terminal dUTP nick-end labeling assay accordingly. The protein expression levels of A20 and tumor necrosis factor receptor 1 (TNFR1)-related signaling molecules were evaluated by Western blot, and co-expression of A20 and TNFR1-associated death domain (TRADD) and co-expression of A20 and receptor-interacting protein 1 (RIP1) were observed by double immunofluorescence staining.
RESULTS The intestinal epithelial barrier was noted to have an improvement in the HPM group of wild-type (WT) mice compared with that in A20IEC-KO mice. Compared with A20 IEC-KO HPM mice, serum endotoxin levels and apoptosis percentages were decreased (P < 0.01), A20 expression levels were increased (P < 0.01), and expression of TNFR1, TRADDD, and RIP1 was decreased in the HPM group of WT mice (PTNFR1 < 0.05, PTRADD < 0.01, PRIP1 < 0.01). Both of the co-expression of A20/TRADD and A20/RIP1 showed a predominantly yellow fluorescence in the HPM group of WT mice, while a predominantly red fluorescence was noted in the HPM group of A20IEC-KO mice.
CONCLUSION Our findings suggest that HPM in treating Crohn’s disease functions possibly via upregulation of the A20 expression level, resulting in downregulation of TNFR1, TRADD, and RIP1 to alleviate increased cell apoptosis in the intestinal epithelial barrier in Crohn's disease.

Abstract
OBJECTIVE To observe the effect of herbal cake-partitioned moxibustion (Moxi) on tumor necrosis factor (TNF)-α/ TNF receptor 1 (TNFR1)-associated death domain (TRADD) / Fas-associated death domain (FADD) pathway-mediated apoptosis of intestinal epithelial cells in Crohn's disease (CD) rats, so as to explore its underlying mechanisms in the treatment of CD. METHODS Forty-eight SD male rats were randomly divided into normal, model, Moxi and medication groups (n=12 rats in each). The CD model was established by intra-annual perfusion of 2,4,6-trinitrobenzene sulfonic acid (TNBS) solution (TNBS∶50% alcohol=2∶1, 3 mL/kg), once every 7 days, 4 times altogether. For rats of the Moxi group, moxibustion was given to "Tianshu" (ST25) and "Qihai" (CV6), two moxa-cones every time, once daily for 10 days. For rats of the medication group, intragastric perfusion of mesalazine solution was given twice daily for 10 days. After the treatment, the colonic epithelium tissue was sampled. The epithelial cells were purified and cultured to establish an in vitro intestinal epithelial barrier, and added with TNF-α (a pro-inflammatory factor, 100 ng/mL) in the culture medium for 24 h for making an increased epithelial permeability model. The permeability of intestinal epithelial cell barrier was evaluated by detecting the fluorescence yellow transmittance of the TNF-α-incubated cell medium. Western blot was used to detect the expression levels of TNFR1, TRADD, receptor-interacting protein 1 (RIP1), FADD and zinc finger protein A20 (A20, a ubiquitination enzyme for inhibiting activation of TRADD and RIP1) of the cultured intestinal epithelium cells. The apoptosis of the TNF-α-incubated intestinal epithelial cells was detected by flow cytometry. RESULTS After modeling and compared with the normal group, the fluorescence yellow transmittance of intestinal epithelia cells, apoptosis rate, and expression levels of TNFR1, TRADD, and RIP1 proteins were significantly increased (P<0.001, P<0.01), and the expression of A20 was significantly decreased (P<0.01) in the model group. In comparison with the model group, the fluorescence yellow transmittance of intestinal epithelial cells, the apoptosis rate and expression levels of TRADD, RIP1 and FADD were remarkably down-regulated (P<0.001, P<0.01), and the expression of A20 was significantly up-regulated (P<0.01) in both the Moxi and medication groups. CONCLUSION Herbal cake-partitioned moxibustion may down-regulate the permeability of intestinal epithelial barrier and the apoptosis of intestinal epithelial cells by way of suppressing TNF-α-mediated cellular apoptosis pathway of intestinal epithelium in CD rats.

Abstract
Lung cancer remains the most common cause of tumor-related death worldwide. Recent studies have revealed that long non-coding RNAs (lncRNAs) are involved in the development of various cancers, including lung cancer. This study aimed to investigate the effect and the molecular basis of lncRNA PICART1 on lung cancer. We first assessed the PICART1 expression in lung cancer in vitro and vivo by qRT-PCR. Then the expression of PICART1 in SPC-A-1 and NCI-H1975 cell lines was inhibited and overexpressed by transient transfections. Thereafter, cell viability, cell cycle, migration and apoptosis were respectively measured by MTT, Transwell and flow cytometry assay. Furthermore, qRT-PCR and western blot analysis were mainly performed to assess the expression levels of apoptosis- and migration-related proteins and JAK2/STAT3 pathway proteins. Tumor formation was measured by xenograft tumor model assay in vivo. PICART1 expression was down-regulated in human lung cancer tissues and cell lines. Knockdown of PICART1 increased cell viability of lung cancer cell lines. However, PICART1 overexpression inhibited cell cycle progression and promoted apoptosis in SPC-A-1 and NCI-H1975 cell lines. PICART1 overexpression also inhibited migration, as evidenced by up-regulation of E-cadherin, and down-regulation of Twist1, MMP2 and MMP9. Furthermore, we found PICART1 inhibition may regulate cell apoptosis and migration through activating JAK2/STAT3 pathway. In vivo experiments revealed that PICART1 knockdown significantly promoted tumor formation. This study demonstrates that PICART1 overexpression represents an anti-growth and anti-metastasis role in lung cancer cells. Additionally, PICART1 acts as a tumor suppressor may be via regulation of JAK2/STAT3 pathway.

Abstract
The optical constants of five highly transparent substrates (polycrystalline BaF2, CaF2, MgF2, ZnSe, and ZnS) were experimentally determined based on a combined technique using both the double optical pathlength transmission method and the ellipsometry method within temperature range 20°C-350°C in the ultraviolet-infrared region (0.2-20 μm). The results show that the refractive index spectra of polycrystalline BaF2, CaF2, and MgF2 are similar, but differ from that of polycrystalline ZnSe and ZnS. The thermo-optic coefficient of these highly transparent substrates increases with increasing temperature. The absorption indices show a significant temperature-dependent behavior, which increases with increasing temperature from 20°C to 350°C over the transparent region. For the sake of application, the fitted formulas of the refractive index of the five highly transparent substrates as a function of wavelength and temperature are presented.

Abstract
Hepatitis B virus (HBV) covalently closed circular DNA (cccDNA) in infected hepatocytes is the main cause of off-therapy viral rebound. The half-life of cccDNA is only 33-50 days, so the conversion of newly synthesized rcDNA to cccDNA in the nucleus is essential for the maintenance of cccDNA pool in infected hepatocytes. Though not directly targeting the existing cccDNA, current nucleos(t)ide analogues (NAs) may exhaust the cccDNA reservoir by blocking the rcDNA formation. Indeed, a prolonged consolidation therapy post loss of serum HBV DNA can achieve sustained remission and thus safe drug discontinuation in a small proportion of chronic hepatitis B (CHB) patients. In recent studies, we and others have demonstrated that it is the serum HBV RNA that reflects the cccDNA activity in infected hepatocytes, particularly among the patients on NAs. Here we suggest that instead of measuring serum HBV DNA only, simultaneous measurement of both viral DNA and RNA would improve the accuracy to reflect the cccDNA activity; therefore, the virological response should be redefined as consistent loss (less than the lower limit of detection) of both serum HBV DNA and RNA, which indicates the safety of drug discontinuation. Accumulating evidence has suggested that for the CHB patients with lower serum HBsAg, switch-to or add-on pegylated interferon (Peg-IFN) treatment would result in loss of serum HBsAg in a relatively large proportion of CHB patients. Since serum HBV RNA is an ideal biomarker to reflect the intrahepatic cccDNA activity, for the patients with a serum HBsAg level lower than 1 500 IU/ml after long-term NAs treatment, the serum HBV RNA should be measured. If serum HBV RNA is detected, peg-IFN should be added on; if serum HBV RNA is not detected, NAs treatment should be switched to peg-IFN treatment. We believe the therapy based on serum HBV RNA would make the functional cure of CHB (serum HBsAg loss or even conversion to anti-HBs) more efficient.

Abstract
AIM To observe whether there are differences in the effects of electro-acupuncture (EA) and moxibustion (Mox) in rats with visceral hypersensitivity.
METHODS EA at 1 mA and 3 mA and Mox at 43 °C and 46 °C were applied to the Shangjuxu (ST37, bilateral) acupoints in model rats with visceral hypersensitivity. Responses of wide dynamic range neurons in dorsal horns of the spinal cord were observed through the extracellular recordings. Mast cells (MC) activity in the colons of rats were assessed, and 5-hydroxytryptamine (5-HT), 5-hydroxytryptamine 3 receptor (5-HT3R) and 5-HT4R expressions in the colons were measured.
RESULTS Compared with normal control group, responses of wide dynamic range neurons in the dorsal horn of the spinal cord were increased in the EA at 1 mA and 3 mA groups (1 mA: 0.84 ± 0.74 vs 2.73 ± 0.65, P < 0.001; 3 mA: 1.91 ± 1.48 vs 6.44 ± 1.26, P < 0.001) and Mox at 43 °C and 46 °C groups (43 °C: 1.76 ± 0.81 vs 4.14 ± 1.83, P = 0.001; 46 °C: 5.19 ± 2.03 vs 7.91 ± 2.27, P = 0.01). MC degranulation rates and the expression of 5-HT, 5-HT3R and 5-HT4R in the colon of Mox 46 °C group were decreased compared with model group (MC degranulation rates: 0.47 ± 0.56 vs 0.28 ± 0.78, P < 0.001; 5-HT: 1.42 ± 0.65 vs 7.38 ± 1.12, P < 0.001; 5-HT3R: 6.62 ± 0.77 vs 2.86 ± 0.88, P < 0.001; 5-HT4R: 4.62 ± 0.65 vs 2.22 ± 0.97, P < 0.001).
CONCLUSION The analgesic effects of Mox at 46 °C are greater than those of Mox at 43 °C, EA 1 mA and EA 3 mA.

Abstract
OBJECTIVE To evaluate the feasibility, safety and efficiency of ex situ liver resection (ESLR)technique in patients with hepatocaval region involvement. METHODS A systematic research of the data bases CNKI, Wan Fang, CQVIP, PubMed, CENTRAL, Medline, Embase, Cochrane, International Clinical Transplantation Registration Platform and Transplant Library was performed. All the current data regarding the feasibility, safety, and oncological efficiency of ESLR was systematically reviewed. Feasibility, conversion to allo-transplantation rate, complication and 90-day mortality were analyzed. RESULTS A literature search revealed a total of 46 publications with 191 patients who underwent ex situ liver resection (101 autotransplantation, 90 ante-situm liver resection). The most common indication was hepatocellular carcinoma (49), followed by colorectal liver metastasis (37), hepatic alveolar echinococcosis (33) and cholangiocarcinoma (26). The feasibility rate was 84.5% (CI=76.6%-90.1%), the conversion to allo-transplantation rate was 13.5% (CI=8.5%-21.0%). Overall complication rate was 58.1% (CI=48.5%-67.1%), and complications grade Ⅲa or higher occurred in 43.1% (CI=33.6%-53.1%).90-day mortality was 19.5% (CI=12.7%-28.8%). CONCLUSION ESLR and autotransplantation technique is an effective surgical approach for hepatic tumor with hepatocaval region involvement. Strict control of surgical indications, preoperative evaluation and precise surgical technique is essential to success.

Abstract
Objective: To investigate the clinical significance of accurate assessment of "volume and quality" of functional liver in Autologous liver transplantation (ALT) in the treatment of the advanced hepatic alveolar echinococcosis (HAE). Methods: The clinical data of 12 patients with advanced HAE who underwent ALT at the First Affiliated Hospital of Xinjiang Medical University from May 2015 to July 2016 were retrospectively analyzed. Results: The preoperative hepatic functions of 12 patients were 8 Child-Pugh Grade A, 1 Grade B, and 3 Grade C. Three of the patients had moderate or severe jaundice. Three of the patients calculated functional liver graft volume (GV) and standard liver volume (SLV) ratio (GV/SLV) were <30%. After the protection of liver function, anti-infection, percutaneous transhepatic cholangiography drainage (PTCD), selective portal vein embolization (PVE), and staging liver resection, liver function Child-Pugh grade of 11 patients was raised to A grade, and the other patient was B grade, meanwhile the bilirubin was reduced to 2 times the normal value. The GV/SLV ratios of 3 patients with low GV/SLV ratio had reached 44.4%, 47.2% and 56.2% respectively. In this study, the GV/SLV ratios of the 12 patients were between 73.2% and 40.8% with an average of 55.6%. Operation time was 11.5-20.5 h, with an average of 12.3 h. Anhepatic phase time was 193-375 min with median 253.5 min. The red blood cell suspension was 0-6 U during the operation. The average hospitalization was 10-42 d, with the average 22.7 d. Total hospital costs were 121 600-434 800 Yuan, with the median cost of 174 400 Yuan. One patient died of septic shock a week after surgery. Conclusion: (1)ALT may provide feasibility for the advanced HAE. (2)Accurate assessment of functional liver "volume and quality" appeared as the key points to the ALT. (3)Precise surgery and individualized treatment could improve and protect the functional liver "volume and quality" .

Abstract
Extinction coefficients are fundamental for analyzing radiative transport in micro/nano particle suspensions. In the traditional transmission method for measuring the extinction coefficient of particles in a cuvette, a reference system is used to compensate for the influence of the cuvette and base fluid. However, the multiple reflections and refractions between the air-glass and liquid-glass interfaces cannot be sufficiently eliminated by using the reference system, and the induced measurement error increases significantly with increasing difference in refractive index between the two neighboring media at these interfaces. In this paper, an improved transmission method is proposed to measure the extinction coefficient of micro/nano particles. The extinction coefficient of the particles is determined based on an optical model, taking into account the multiple reflection and refraction at the glass-liquid interfaces. An experimental validation was conducted for suspensions with various mean particle sizes. By considering the higher-order transmission terms, the improved transmission method generally achieved high-accuracy improvement over the traditional transmission method for extinction coefficient measurement, especially for the case with a small optical thickness of particle suspensions. This work provides an alternative and more accurate way for measuring the extinction characteristics of micro/nano particle suspensions.

An abdominal withdrawal reflex (AWR) score was used to assess visceral hypersensitivity. Toluidine blue staining was used to assess mast cell (MC) activity in colon of rats. Immunochemistry was used to measure 5-HT and 5-HT4 receptor expression in the colon. Results. AWR scores in all EA (1 mA and 3 mA) and Mox (43°C and 46°C) treatment groups after colorectal distention (CRD) stimulation pressure of 20, 40, 60, and 80 mmHg were significantly lower than those of the model (MC) group (P all < 0.01). The MC counts and degranulation rates in the colon of all EA and Mox treatment groups and the MC group were significantly higher than those of the NC group (P all < 0.01). MC degranulation rates in the colon of all EA and Mox treatment groups were lower than those of the MC group (P all < 0.05). 5-HT expression in colon of all EA and Mox treatment groups was significantly lower than that of the MC group (P all < 0.01), and 5-HT4R expression in colon of both EA groups was significantly higher than that of the MC group (P both < 0.01). Conclusion. EA and Mox treatments may both ameliorate visceral hypersensitivity at different degree in rats with C-IBS, and EA treatment was better than Mox.

Abstract
OBJECTIVE To compare the effects of electroacupuncture (EA) and moxibustion (Moxi) on visceral pain and expression of vanilloid receptor subtype 1 (VR 1) and heat shock protein (HSP)70 in "Tianshu" (ST 25) region in colorectal distension (CRD)-induced visceral hypersensitivity (VHS) rats. METHODS Fifty male SD rats were randomly divided into normal control, VHS model, 43℃-moxi, 46℃-moxi, 1 mA-EA and 3 mA-EA groups (n=10 in each group). The VSH model was established by CRD once daily for 14 days. EA or Moxi stimulation was applied to bilateral "Tianshu" (ST 25) for 10 min, once daily for consecutive 10 days. The abdominal withdrawal reflex (AWR) scores (0-4 points) were rated according to Al-Chaer's and coworkers' standards (2000) and the expression levels of VR 1 and HSP 70 in bilateral ST 25 area tissues detected by immunohistochemistry. RESULTS The AWR scores for 20, 40, 60 and 80 mmHg CRD pressures were significantly increased compared to the normal control group (P<0.01) and notably decreased after 43℃- and 46℃-moxi, and 1 mA- and 3 mA-EA stimulation of bila-teral ST 25 in comparison with the model group (P<0.05, P<0.01), and the effect of 46℃-moxi was apparently superior to those of 1 mA-EA at 40 and 80 mmHg, and 3 mA-EA at 40 mmHg (P<0.05). After modeling, the expression of both VR 1 and HSP 70 (percentages of area of positive-cells) in ST 25 region had no significant changes (P>0.05). Compared to the model group, the expression levels of VR 1 in the 43℃-moxi and 46℃-moxi groups, and HSP 70 in the 43℃-moxi and 46℃-moxi, 1 mA-EA and 3 mA-EA groups were significantly up-regulated (P<0.01), but without obvious changes in the expression of VR 1 in the 1 mA-EA and 3 mA-EA groups (P>0.05). The effects of 46℃-moxi were considerably better than those of 43℃-moxi, 1 mA-EA and 3 mA-EA in up-regulating VR 1 and HSP 70 expression (P<0.05, P<0.01). No significant differences were found among the 43℃-moxi, 1 mA-EA and 3 mA-EA groups in the expression of VR 1 and HSP 70 (P>0.05). CONCLUSIONS Moxibustion at 43℃ and 46℃ and EA at 1 mA and 3 mA, especially the 46℃-moxi, can relieve visceral pain in visceral hypersensitivity rats, which may be related to their effects in up-regulating expression of VR 1 and HSP 70 in "Tianshu" (ST 25) area.

Abstract
OBJECTIVE To investigate the clinicopathological features of different stages of primary biliary cirrhosis (PBC), and to provide a basis of evidence-based medicine for early identification and effective treatment of this disease. METHODS A total of 130 patients with pathologically confirmed PBC and complete clinical data were enrolled and divided into early-stage group and late-stage group based on pathological results. A retrospective analysis was performed for patients' general information, clinical manifestations, laboratory examinations, and pathological changes. RESULTS The PBC patients had a mean age of 43.5±7.1 years, with middle-aged female patients accounting for 89%. The most common symptom was fatigue, followed by jaundice, pruritus, and abdominal distension in the late stage. Of all patients, 11.5% were complicated by autoimmune disease. The level of aminotransferases tended to decrease with the progression of PBC and showed no significant differences between the two groups (P > 0.05). Most patients showed an increase in serum bilirubin, mainly direct bilirubin; serum total bilirubin and direct bilirubin tended to increase with disease progression and showed significant differences between the two groups (P < 0.01). The patients showed increases in the serum levels of alkaline phosphatase (ALP) andγ-glutamyl transpeptidase (GGT), but with the disease progression, the serum level of ALP increased and that of GGT decreased; the serum levels of ALP and GGT showed no significant differences between the early- and late-stage groups (P > 0.05). The positive rate of antimitochondrial antibody was 85%. The histopathological changes of PBC included severe lesions in the portal area and surrounding areas and slight lobular lesions. In the early stage, there were injuries of the interlobar bile ducts, proliferation of small bile ducts, aggregation and invasion of mononuclear cells in surrounding tissues, and the formation of lymphoid follicle-like structure; in the late stage, there were fibrotic expansion of the portal area, formation of fibrous septa and pseudolobuli, and even liver cirrhosis. CONCLUSION PBC is commonly seen in middle-aged women and has an insidious onset. Early- and late-stage PBC have their own clinicopathological features. As for patients with no characteristic changes in serological test, liver biopsy should be performed to give a confirmed diagnosis and avoid missed diagnosis and misdiagnosis.

Abstract
Inflammatory bowel disease (IBD) is a complex chronic inflammatory disorder caused by the interaction of environmental, hereditary and immune factors. The etiology and pathogenesis of IBD remain unveiled. In recent years, growing attention has been paid to the role of vitamin D in immune-related diseases like IBD from traditional bone metabolism. Vitamin D not only participates in calcium and phosphorus metabolism but also alleviates IBD via regulating the immune cell factors, inducing antimicrobial peptide expression and maintaining the integrity of intestinal mucosal barrier. In view of anti-inflammatory and immunomodulatory activities of vitamin D, this article discusses its role in IBD.

Abstract
OBJECTIVE To study the interactive effects of Type II glutamine transaminase (TG2) and bone morphogenetic protein-9 (BMP-9) in the induction of osteogenesis in mice mesenchymal stem cells (MSCs) C3H10T1/2 model. MATERIALS AND METHODS Batches of MSCs C3H10T1/2, divided into two groups, were treated with BMP-9 (control group) or BMP-9 and TG2 (experimental group) under oxygen deficient conditions. The secreted alkaline phosphatase (SEAP) chemiluminescence and the histochemical staining methods were used to detect the alkaline phosphatase (ALP) expression. The alizarin red S staining was used to detect the calcium salt precipitation and the caspase-3 protein expression was monitored using Western blot. Flow cytometry was employed to identify cell cycle, and trypan blue exclusion method to count the living cells and monitor cell proliferation. RESULTS The levels of ALP expression in the experimental group were much higher than that of the control group. The level of expression of advanced caspase-3 protein was significantly lower (p < 0.05) in the experimental group than in the control group. The highest fraction of cells in the experimental group was in the phase M while cells in the control group were in the interphase. Moreover, cell number in the experimental group was significantly increased (p < 0.05) relatively to the control group. CONCLUSIONS BMP-9 interacts with TG2 in osteogenesis of MSCs C3H10T1/2 cells. Further studies are needed to understand the exact mechanism of BMP9/PG2 interactions in osteogenesis.

Abstract
Planarians, which have a large population of stem cells called neoblasts, are molecularly tractable model systems used in the study of regeneration. However, planarians have strong resistance to hunger and have developed growth arrest strategies. For example, they can change their size and undergo growth regression during starvation periods. The results of the current study show that the microRNA, miR-71b, and the insulin/IGF-1 signaling pathway have important functions in the development of starvation-induced planarians. We demonstrate tissue-specific expression of miR-71b using in situ hybridization. By employing real-time polymerase chain reaction, we provide evidence that miR-71b is upregulated in starvation-induced planarians. Furthermore, we validate and verify the target genes of miR-71b.

Abstract
Available phosphate (Pi) is a major limiting factor for plant growth, development, and productivity. Phosphate starvation response 1 (PHR1) is a binding dimer that binds to an imperfect palindromic sequence. PHR1-binding sequences (GnATATnC) exist in the promoter of Pi starvation-responsive structural genes, indicating an effect occurring downstream in the Pi starvation signaling pathway. These sequences are referred to as PHR1-binding site (P1BS) structures. In this study, the sequences of GmPHR1 and GmSPX1 from Glycine max (L.) Merr. soybean were determined and analyzed. We found that GmPHR1 is an MYB-related transcription factor. In addition, GmSPX1 contained a P1BS structure, which is an important cis-regulatory motif in the phosphate signaling pathway. We found that GmPHR1 can physically interact with GmSPX1 through the cis-element, which may be a major pathway for the GmPHR1-mediated Pi starvation stress response. Thus, the P1BS structure in the Pi starvation signaling pathway is an important cis-regulatory motif that improves the tolerance to low phosphorus conditions in soybean.

Abstract
AIM: To investigate the effect of herb-partitioned moxibustion combined with acupuncture on the expression of intestinal epithelial tight junction (TJ) proteins.
METHODS: Sixty patients diagnosed with mild to moderate Crohn’s disease (CD) were allocated into the herb-partitioned moxibustion combined with acupuncture (HMA) group (n = 30) or the mesalazine (MESA) group (n = 30) using a parallel control method. There were 2 sets of acupoints used alternately for HMA treatment. The following points were included in Set A: ST25 (Tianshu), RN6 (Qihai), and RN9 (Shuifen) for herb-partitioned moxibustion and ST36 (Zusanli), ST37 (Shangjuxu), LI11 (Quchi), and LI4 (Hegu) for acupuncture. The points for Set B included BL23 (Shenshu) and BL25 (Dachangshu) for herb-partitioned moxibustion and EX-B2 of T6-T1 (Jiajixue) for acupuncture. The patients received the same treatment 6 times a week for 12 consecutive weeks. The MESA group received 1 g of mesalazine enteric coated tablets 4 times daily for 12 consecutive weeks. Intestinal tissues were stained and examined to compare the morphological and ultrastructural changes before and after the treatment session. Immunohistochemistry and in situ hybridization assays were used to detect the expression of intestinal epithelial TJ proteins zonula occludens-1 (ZO-1), occludin, and claudin-1. The mRNA levels were also evaluated.
RESULTS: After the treatment, both herb-partitioned moxibustion combined with acupuncture and mesalazine improved intestinal morphology and ultrastructure of CD patients; the patients treated with HMA showed better improvement. HMA significantly increased the expression of ZO-1 (P = 0.000), occludin (P = 0.021), and claudin-1 (P = 0.016). MESA significantly increased the expression of ZO-1 (P = 0.016) and occludin (P = 0.026). However, there was no significant increase in the expression of claudin-1 (P = 0.935). There was no statistically significant difference between the two groups for the expression of occludin and claudin-1 (P > 0.05). The HMA group showed a significant improvement in ZO-1 expression compared to the MESA group (2333.34 ± 352.51 vs 2160.38 ± 307.08, P = 0.047). HMA significantly increased the expression of ZO-1 mRNA (P = 0.000), occludin mRNA (P = 0.017), and claudin-1 mRNA (P = 0.017). MESA significantly increased the expression of ZO-1 mRNA (P = 0.000), occludin mRNA (P = 0.042), and claudin-1 mRNA (P = 0.041). There was no statistically significant difference between the two groups in the expression of occludin and claudin-1 mRNA (P > 0.05). However, the HMA group showed a significant improvement in ZO-1 mRNA expression compared with the MESA group (2378.17 ± 308.77 vs 2200.56 ± 281.88, P = 0.023).
CONCLUSION: HMA can repair intestinal epithelial barrier lesions and relieve inflammation by upregulating the expression of TJ proteins and their mRNAs.

Abstract
A simple chemical method was established for inducing bioactivity of Ti metal. In the present study, two kinds of mixed acid solutions were used to treat Ti specimens to induce Ca-P formation. Following a strong mixed acid activation process, Ca-P coatings successfully formed on the Ti surfaces in the simulated body fluid. Strong mixed acid etching was used to increase the roughness of the metal surface, because the porous and rough surfaces allow better adhesion between Ca-P coatings and substrate. Nano-scale modification of titanium surfaces can alter cellular and tissue responses, which may benefit osseointegration and dental implant therapy. Some specimens were treated with a 5 M NaOH aqueous solution, and then heat treated at 600 °C in order to form an amorphous sodium titanate layer on their surface. This treated titanium metal is believed to form a dense and uniform bone-like apatite layer on its surface in a simulated body fluid (SBF). This study proved that mixed acid treatment is not only important for surface passivation but is also another bioactive treatment for titanium surfaces, an alternative to alkali treatment. In addition, mixed acid treatment uses a lower temperature and shorter time period than alkali treatment.

Abstract
AIM: To identify an appropriate therapeutic regimen for using aconite cake-separated moxibustion to treat diarrhea-predominant irritable bowel syndrome (D-IBS).
METHODS: A factorial design was employed to examine the two factors of moxibustion frequency and number of cones. The two tested frequencies were three or six moxibustion sessions per week, and the two tested doses were one or two cones per treatment. A total of 166 D-IBS patients were randomly divided into four treatment groups, which included each combination of the examined frequencies and doses. The bilateral Tianshu acupoints (ST25) and the Qihai acupoint (RN6) were selected for aconite cake-separated moxibustion. Each patient received two courses of treatment, and each course had a duration of 2 wk. For each group, the scores on the Birmingham irritable bowel syndrome (IBS) symptom questionnaire, the IBS Quality of Life scale, the Self-Rating Depression Scale (SDS), the Self-Rating Anxiety Scale (SAS), the Hamilton Depression (HAMD) scale, and the Hamilton Anxiety (HAMA) scale were determined before treatment, after the first course of treatment, and after the second course of treatment.
RESULTS: The symptom, quality of life, SDS, SAS, HAMD, and HAMA scores of the patients in all 4 aconite cake-separated moxibustion groups were significantly lower after the first and second courses of treatment than before treatment (P < 0.001 for all). The symptom, quality of life, SDS, SAS, HAMD, and HAMA scores of the patients in all four aconite cake-separated moxibustion groups were significantly lower after the second course of treatment than after the first course of treatment (P < 0.001 for all). Between-group comparisons after the second course of treatment revealed that the symptom scores for group 1 (1 cone, 3 treatments/wk) and group 3 (2 cones, 3 treatments/wk) were significantly lower than that for group 2 (1 cone, 6 treatments/wk) (5.55 ± 5.05 vs 10.45 ± 6.61, P < 0.001; 5.65 ± 4.00 vs 10.45 ± 6.61, P < 0.001). Regarding the two levels of the two examined factors for aconite cake-separated moxibustion, after the first course of treatment, the changes in HAMA scores were significantly different for the two tested moxibustion frequencies (P = 0.011), with greater changes for the “6 treatments/wk” groups than for the “3 treatments/wk” groups; in addition, there were interaction effects between the number of cones and moxibustion frequency (P = 0.028). After the second course of treatment, changes in symptom scores for the 2 tested moxibustion frequencies were significantly different (P = 0.002), with greater changes for the “3 treatments/wk” groups than for the “6 treatments/wk” groups.
CONCLUSION: An aconite cake-separated moxibustion treatment regimen of 3 treatments/wk and 1 cone/treatment appears to produce better therapeutic effects for D-IBS compared with the other tested regimens.

Abstract
The effect of thermo-cycling treatment on the bond strength and flexural strength of porcelain veneered zirconia was evaluated. After thermo-cycling treatment between 5 degrees C to 55 degrees C, porcelain-zirconia bond strength and zirconia flexural strength was not significantly affected. In the phase analyses using XRD after thermo-cycling treatment, both the experimental group and the control group showed only tetragonal phases. That is, the porcelain-zirconia bond strength and zirconia flexural strength were not affected by low temperature degradation. So low temperature aging treatment did not reduce the flexural strength and the effect of temperature applied to the aging treatment could beignorable.

Abstract
AIM: To evaluate the clinical efficacy and safety of acupuncture and moxibustion for the treatment of active Crohn’s disease (CD).
METHODS: Ninety-two patients were equally and randomly divided into the treatment group and received herb-partitioned moxibustion combined with acupuncture, and the control group received wheat bran-partitioned moxibustion combined with superficial acupuncture. The patients received three treatment sessions per week for 12 wk and were followed up for 24 wk. The main outcome was evaluated using the CD Activity Index (CDAI) score, and the secondary outcomes were evaluated using laboratory indicators such as hemoglobin (HGB), C-reactive protein (CRP), erythrocyte sedimentation rate, quality-of-life, endoscopic ratings, and intestinal histology scores.
RESULTS: The CDAI scores of both the treatment and control groups were significantly reduced after treatment compared with those measured before treatment. However, the degree of improvement in the treatment group was significantly greater than that of the control group. The improvement in symptoms in patients of the treatment group was sustained at follow-up, whereas that of the control group was not. The overall efficacy of the treatment was significantly greater than that of the control. Both groups demonstrated significant improvements in quality-of-life ratings after treatment, but the improvement was significantly greater in the treatment group than in the control group. In addition, the patients in the treatment group showed significantly increased HGB and significantly decreased CRP levels and histopathological scores at the end of treatment, whereas the control group did not exhibit significant changes.
CONCLUSION: Moxibustion with acupuncture provided significant therapeutic benefits in patients with active CD beyond the placebo effect and is therefore an effective and safe treatment for active CD.

Abstract
The objective of this experiment was to measure the apparent total tract digestibility (ATTD) and the retention rate of Zn, Cu, Mn, and Fe in pigs fed either inorganic or organic sources of Zn, Cu, Mn, and Fe. The experimental design was a randomized complete block design with a 2 × 3 factorial arrangement of treatments. There were 2 types of diets (corn grits-based or corn-soybean meal [SBM]-based diets) and 3 micromineral treatments (basal micromineral premix [BMM], inorganic micromineral premix [IMM], and organic micromineral premix [OMM]). The BMM contained no added Zn, Cu, Mn, or Fe; the IMM microminerals were provided as sulfates of Zn, Cu, Mn, and Fe at 40, 50, 20, and 100 mg/kg, respectively. The OMM contained the same levels of the 4 microminerals as IMM, but Zn, Cu, Mn, and Fe in this premix were provided by Zn(2-hydroxy-4-methylthio butanoic acid [HMTBa])2, Cu(HMTBa)2, Mn(HMTBa)2, and FeGly, respectively. Forty-eight barrows (initial BW: 31.1 ± 4.2 kg) were housed individually and allowed ad libitum access to the corn grits diet with BMM for 2 wk. All pigs were then moved to metabolism cages and randomly assigned to 1 of the 6 treatment diets with 8 replicates per diet. Fecal and urine samples were collected for 5 d following a 5-d adaptation period. Compared with corn grits diets, pigs fed corn-SBM diets had greater (P < 0.05) absorption and retention of Zn, Cu, and Mn but less (P < 0.05) ATTD of Zn and Cu. Compared with BMM, supplementation of IMM or OMM increased (P < 0.05) absorption, retention, ATTD, and retention rate of Zn, Cu, Mn, and Fe. Compared with IMM, adding OMM to the corn-SBM diet improved (P < 0.05) the absorption and retention of Cu and Mn and the ATTD of Cu, but these differences were not observed in the corn grits diets (interaction, P < 0.05). In addition, adding OMM to the corn-SBM diet increased (P < 0.05) absorption and retention of Zn and Fe and ATTD of Zn, Mn, and Fe compared with adding IMM to the corn-SBM diet. Supplementation of OMM also increased (P < 0.05) the ATTD and retention rate of P in corn-SBM diets. Results indicate that Zn(HMTBa)2 has greater digestibility and Cu(HMTBa)2 and Mn(HMTBa)2 have greater digestibility and retention rates compared with their inorganic sulfates, if included in a corn-SBM diet. Supplementation of organic microminerals also improves the digestibility of P in a corn-SBM diet.

Abstract
Tissue engineering encapsulated cells such as chondrocytes in the carrier matrix have
been widely used to repair cartilage defects. However, chondrocyte phenotype is
easily lost when chondrocytes are expanded in vitro by a process
defined as “dedifferentiation”. To ensure successful therapy, an effective
pro-chondrogenic agent is necessary to overcome the obstacle of limited cell numbers
in the restoration process, and dedifferentiation is a prerequisite. Gallic acid (GA)
has been used in the treatment of arthritis, but its biocompatibility is inferior to
that of other compounds. In this study, we modified GA by incorporating
sulfamonomethoxine sodium and synthesized a sulfonamido-based gallate, JJYMD-C, and
evaluated its effect on chondrocyte metabolism. Our results showed that JJYMD-C could
effectively increase the levels of the collagen II, Sox9, and aggrecan genes, promote
chondrocyte growth, and enhance secretion and synthesis of cartilage extracellular
matrix. On the other hand, expression of the collagen I gene was effectively
down-regulated, demonstrating inhibition of chondrocyte dedifferentiation by JJYMD-C.
Hypertrophy, as a characteristic of chondrocyte ossification, was undetectable in the
JJYMD-C groups. We used JJYMD-C at doses of 0.125, 0.25, and 0.5 µg/mL, and the
strongest response was observed with 0.25 µg/mL. This study provides a basis for
further studies on a novel agent in the treatment of articular cartilage defects.

Abstract
Here, we aimed to clone and identify the GmIMT1 gene related to the salt stress response in soybean. The full-length cDNA sequence of the GmIMT1 gene was amplified in soybean using degenerate primers of Mesembrythmum crystallium. To understand the stress response, the GmIMT1 gene was cloned and sequenced. Then, the expression vectors of the gene were constructed, and introduced into the model plant Arabidopsis thaliana through Agrobacterium mediated transformation, and the salt tolerance was analyzed in the transgenic plants. In addition, the expression patterns of GmIMT1 gene in soybean were analyzed. The expression was examined in different organs (roots, leaves, flower seeds, and stem) and under different stress conditions (drought, high salt, low temperature, salicylic acid, ethane, abscisic acid, and methyl jasmonate) by real-time fluorescent quantitative polymerase chain reaction analysis. The results showed that the root, leaves, and stems exhibited high level of GmIMT1 gene expression, whereas there was no expression in the seeds. In addition, the GmIMT1 gene expression was upregulated under all stress conditions. Overall, the results clearly indicate that GmIMT1 might be involved in multiple plant response pathways to the different environmental conditions. Furthermore transgenic plants exhibited higher salt-tolerance compared to wild type plants.

Abstract
PURPOSE The arguments about whether posterior-substituting prostheses or cruciate-retaining prostheses are superior to the other after total knee arthroplasty never stop. This meta-analysis was conducted to evaluate the clinical effects of these two different designs. METHODS The study was performed according to the guidelines described in the Cochrane handbook for systematic reviews of interventions. Methodological features were collected and extracted by two reviewers independently. RESULTS Nine randomized controlled trials with 1261 knees were eligible for pooled analysis. The meta-analysis demonstrated there were no statistical differences in the Knee Society Score, Hospital for Special Surgery, Western Ontario and McMaster Universities index, tibial component alignment, femoral component alignment, tibial posterior slope, joint line, and incidence of complications with short-to medium-term follow-up (p>0.01). Statistically difference in postoperative range of motion (WMD: 4.34°, 95% CI: 3.18° to 5.50°) in favor of PS prostheses was found between groups (p<0.01). CONCLUSION The findings indicate there were no significant statistical differences in knee scores, radiological outcomes, and complications between the two types of implants. Statistically significant difference in postoperative ROM was found between the two groups, but no clinical difference.

Abstract
The experimental pharmacological research on Ma-Huang and Tang-Kuei (Danggui) by Chen Kokuei and his colleagues in 1923, is the proem of scientific research on Chinese materia medica (CMM) in China. In the 1930's, a number of scientific research institutions were established in China, such as, the Institute of Physiology, National Academy of Peiping and the pharmaceutical laboratory of the experimental hygiene station, National Economic Council. Experts undertook extensive research on CMM. They injected the rough extractum or purified active constituent in laboratory animals to observe the characteristics of drugs and published a series of treatises. They made experimental objectives and selected experimental herbs according to TCM theory. Their inheritance and innovation in the research demonstrated better rationality than simultaneous overseas scholars to whom they were therefore superior.

Abstract
Population genetic studies were performed in Chinese Han, Hui, Mongolian, Tibetan and Uygur. Allele frequency distributions were analyzed for ten loci, i.e., D3S1358, VWA, CSF1PO, FGA, THO1, TPOX, D5S818, D13S317 and D7S820 by GeneScan. The results showed that there were 60 STR alleles and 149 genotypes in Han; 63 STR alleles and 144 genotypes in Hui; 69 STR alleles and 173 genotypes in Mongolian; 77 STR alleles and 168 genotypes in Tibetan; 70 STR alleles and 148 genotypes in Uygur. Significant differences were identified among ethnic groups (African-American, US-Caucasian and Chinese-Oriental), but similarity was found among the five Chinese populations, and immunogenomics and pharmacogenomics studied in this report. These findings indicated that the nine STR loci and amelogenin locus were very useful for individual identification in forensic science.

Abstract
A method for the determination of main composition in degraded products of penicillin, 6-aminopenicillanic acid (6-APA), penicillin G kalium (PGK), phenylacetic acid (PAA), and the by-product benzylpenicilloic acid (BPA) by HPLC was studied. Separation conditions were as follows: Spherisorb C18 column, 250 mm x 4.6 mm i.d., 10 micrograms; mobile phase: V (methanol): V(0.004 mol/L KH2PO4 buffer, pH 4.5) = 50:50; flow rate: 1 mL/min; detector: UV 230 nm. The method is effective, quick, accurate and reproducible. The satisfactory results show that this new method has certain practical values as an approach of quality control.

Abstract
Seven SUNCT patients (six men, one woman) took part in this study. In four patients, respiratory variables were compared during and outside attacks. In five patients, peripheral chemosensitivity was tested and compared with a control group matched with respect to age, sex, and smoking habits. The results indicate that SUNCT patients hyperventilate during attacks. Moreover, they appear to hyperventilate slightly under basal conditions. The tests for peripheral chemoreceptor activity indicated no differences between the SUNCT and the control groups except for one variable, namely the mean ventilatory response to a single breath of 13% CO2. It is possible that this indicates a blunted response of the peripheral chemoreceptors. On the other hand, it may also represent a chance finding, since none of the other results presented suggested such a conclusion, and the size of the test group was very small. The results do not indicate that a reduction in oxygen saturation can trigger SUNCT since low levels of oxygen saturation were only rarely accompanied by SUNCT, whereas many attacks were not associated with any appreciable lowering in arterial oxygen saturation.

Abstract
SUNCT is a newly described headache characterized by shortlasting, unilateral attacks of a neuralgiform character, accompanied by conjunctival injection and tearing on the symptomatic side. At present, 8 patients have been observed, all males. In the present work, vertical pupillary diameters have been estimated by the binocular, Whittaker infrared pupillometer (Gulf & Western). Measurements have been carried out both during the basal state and after topical, pharmacologic stimulation (by sympathicomimetic agents, i.e. tyramine (2%), OH-amphetamine (1%) and phenylephrine (1%). In the basal state, there was no clear tendency to anisocoria. After sympathicomimetic drugs, there was a tendency to underreaction on the symptomatic side, mainly as regards the indirectly acting ones (OH-amphetamine and tyramine). These two agents should supposedly give similar results, but, nevertheless, the results partly deviated. Phenylephrine did not invariably normalize the symptomatic/non-symptomatic side ratio. Corneal sensitivity was investigated with the Cochet-Bonnet esthesiometer. Two of 6 patients studied outside attack showed moderately lowered values on the symptomatic side. During attack, there seemed to be reduced corneal sensitivity in both patients investigated, in one bilaterally, in the other, on the symptomatic side only.
