Abstract
Objective: To investigate the intravoxel incoherent motion (IVIM) diffusion-weighted imaging (DWI) in the differential diagnosis of diabetic nephropathy (DN) and non-diabetic renal disease (NDRD) among patients with type 2 diabetes mellitus (T2DM). Methods: A diagnostic test. In this prospective study, patients with T2DM who underwent both IVIM-DWI and renal biopsy at the First Medical Center of Chinese PLA General Hospital between October 2017 and September 2021 were consecutively enrolled. IVIM-DWI parameters including perfusion fraction (f), pure diffusion coefficient (D), and pseudo-diffusion coefficient (D*) were measured in the renal cortex, medulla, and parenchyma. Patients were divided into the DN group and NDRD group based on the renal biopsy results. IVIM-DWI parameters, clinical information, and diabetes-related biochemical indicators between the two groups were compared using Student's t-test or Mann-Whitney U test. The correlation of IVIM-DWI parameters with diabetic nephropathy histological scores were analyzed using Spearman's correlation analyzes. The diagnostic efficiency of IVIM-DWI parameters for distinguishing between DN and NDRD were assessed using the receiver operating characteristic (ROC) curves. Results: A total of 27 DN patients and 23 NDRD patients were included in this study. The DN group comprised 19 male and 8 female patients, with an average age of 52±9 years. The NDRD group comprised 16 male and 7 female patients, with an average age of 49±10 years. The DN group had a higher D* value in the renal cortex and a lower f value in the renal medulla than the NDRD group (9.84×10-3 mm2/s vs. 7.35×10-3 mm2/s, Z=-3.65; 41.01% vs. 46.74%, Z=-2.29; all P<0.05). The renal medulla D* value was negatively correlated with DN grades, interstitial lesion score, and interstitial fibrosis and tubular atrophy (IFTA) score (r=-0.571, -0.409, -0.409; all P<0.05) while the renal cortex f value was positively correlated with vascular sclerosis score (r=0.413, P=0.032). The renal cortex D* value had the highest area under the curve (AUC) for discriminating between the DN and NDRD groups (AUC=0.802, sensitivity 91.3%, specificity 55.6%). Conclusion: IVIM-derived renal cortex D* value can be used non-invasively to differentiate DN from NDRD in patients with T2DM that can potentially facilitate individualized treatment planning for diabetic patients.

Abstract
Xujiang School of acupuncture and moxibustion has a long history with distinctive academic characteristics and regional influence. Xujiang School, originated from Xi Hong in Song Dynasty, is the oldest acupuncture and moxibustion school recorded in Chinese history. Later, it was passed down from family to family for more than ten generations. The tenth generation Xi Xinqing passed it on to Chen Honggang and gradually evolved into a school of acupuncture and moxibustion with regional characteristics and a certain national influence. In terms of academic characteristics, doctors in Xujiang School kept innovating based on the Classics.Its acupuncture and moxibustion academic ideas including reinforcement and reduction , point selection and searching for the primary cause of disease in treatment have had an important impact on contemporary acupuncture in clinic.

Abstract
Single-cell RNA sequencing (scRNA-seq) is a powerful approach for studying cellular differentiation, but accurately tracking cell fate transitions can be challenging, especially in disease conditions. Here we introduce PhyloVelo, a computational framework that estimates the velocity of transcriptomic dynamics by using monotonically expressed genes (MEGs) or genes with expression patterns that either increase or decrease, but do not cycle, through phylogenetic time. Through integration of scRNA-seq data with lineage information, PhyloVelo identifies MEGs and reconstructs a transcriptomic velocity field. We validate PhyloVelo using simulated data and Caenorhabditis elegans ground truth data, successfully recovering linear, bifurcated and convergent differentiations. Applying PhyloVelo to seven lineage-traced scRNA-seq datasets, generated using CRISPR-Cas9 editing, lentiviral barcoding or immune repertoire profiling, demonstrates its high accuracy and robustness in inferring complex lineage trajectories while outperforming RNA velocity. Additionally, we discovered that MEGs across tissues and organisms share similar functions in translation and ribosome biogenesis.

Abstract
OBJECTIVE To perform an epidemiological investigation on a case of visceral leishmaniasis reported from Shule County, Kashi Prefecture, Xinjiang Uygur Autonomous Region in 2021, so as to provide insights into differential diagnosis of visceral leishmaniasis during the COVID-19 pandemic. METHODS The epidemiological history of this case was collected, and the case was diagnosed for Leishmania infection with the immunochromatographic (rK39) strip test, bone marrow smear microscopy and PCR assay. RESULTS The patient had typical clinical symptoms of leishmaniasis, including irregular fever, hepatosplenomeg- aly, low serum albumin and elevated globulin. Bone marrow smear microscopy identified L. donovani amastigotes, and both rK39 strip test and PCR assay were positive, while the case was tested negative for SARS-CoV-2. COVID-19 was therefore excluded and visceral leishmaniasis was diagnosed. Standard full-dose treatment with sodium stibogluconate was given, and no Leishmania was found on blood smears during the reexamination. No recurrence was found during the followup after discharge for hospital. CONCLUSIONS During the COVID-19 pandemic, it is recommended to increase the perception of differential diagnosis of visceral leishmaniasis among first-contact doctors, and reinforce the capability of differential diagnosis and health education of visceral leishmaniasis among medical and healthcare institutions at all levels, to prevent missed diagnosis and misdiagnosis of visceral leishmaniasis.

Abstract
Homeodomain-leucine zipper (HD-Zip) proteins are plant-specific transcription factors that play important roles in different biological processes, especially leaf development. However, no studies to date have identified the HD-Zip genes in Liriodendron chinense nor characterized their functions. We identified the HD-Zip genes in L. chinense by analysing the phylogeny, chromosome location, structure, conserved motif, cis-regulatory elements, synteny, post-transcriptional regulation and expression patterns of these genes during leaf development. A total of 36 LcHD-Zip genes were identified and divided into four subfamilies (HD-Zip I to IV). Synteny analysis revealed that segmental duplication was the main force driving the expansion of LcHD-Zip genes. These 36 LcHD-Zip genes exhibited 11 different expression patterns. Pattern 1, 2, 3, 4, 6, 7, 8 and 9 genes may play important roles in leaf development, such as leaf initiation, leaf polarity establishment, leaf shape development, phytohormone-mediated leaf growth and leaf epidermal structure formation. Four HD-Zip III genes were targeted by microRNAs (miRNAs), and the miR165/166a-HD-Zip regulatory module formed regulated leaf initiation and leaf polarity establishment. Overall, LcHD-Zip genes play key roles in leaf development of L. chinense. This work provides a foundation for the functional verification of HD-Zip genes identified in this study.

Abstract
BACKGROUND AND AIMS As a hepatocellular carcinoma biomarker, serum Golgi protein 73 (GP73) is reportedly related to inflammation. Acute-on-chronic liver failure (ACLF) is characterized by severe systemic inflammation. In this study, we aimed to explore the association between the GP73 level and short-term mortality in patients with alcohol-associated liver disease-related ACLF (ALD-ACLF). METHODS This retrospective cohort study involved 126 Chinese adults with ALD-ACLF. Baseline serum GP73 level was measured using enzyme-linked immunosorbent assay. Patients were followed-up for 90 d and outcomes were assessed. Data were analyzed using multivariate Cox regression and piecewise linear regression analyses. The predictive value of GP73 and classic models for the short-term prognosis of participants were evaluated and compared using receiver operating characteristic curves. RESULTS The serum GP73 level was independently associated with an increased mortality risk in patients with ALD-ACLF. Compared with the lowest tertile, the highest serum GP73 level predisposed patients with ALD-ACLF to a higher mortality risk in the fully adjusted model [at 28 days: hazard ratio (HR): 4.29 (0.99-18.54), p=0.0511; at 90 days: HR: 3.52 (1.15-10.79), p=0.0276]. Further analysis revealed a positive linear association. GP73 significantly improved the accuracy of the Child-Turcotte-Pugh score, model for end-stage liver disease score, and model for end-stage liver disease-sodium score in predicting short-time prognosis of patients with ALD-ACLF. CONCLUSIONS The serum GP73 level is a significant predictor of the subsequent risk of death in patients with ALD-ACLF. GP73 improved the predictive value of classic prognostic scores.

Methods: One hundred and forty-two patients with IPA treated in Tianjin Huanhu Hospital from January 2014 to January 2019 were analyzed retrospectively, including 62 males and 80 females, aging from 38 to 67 years. The clinical data of patients before and after operation were collected. All patients with postoperative CFR underwent endoscopic CFR repair. During the operation, residual or recurrent pituitary adenomas were resected, the dura around the leak was enlarged and the necrotic tissue was removed. For those who still had fluid leakage after repair, the necrotic tissue was cleaned up, the leakage was filled and reinforced under endoscopy. Endoscopic rhinorrhea repair was performed if necessary. The cerebrospinal fluid leak was repaired with multi-layer materials. The related risk factors of delayed CFR after operation were analyzed. SPSS 19.0 software was used for statistical analysis. Results: Among the 142 patients in this group, 64 cases underwent total tumor resection and 78 cases underwent non-total tumor resection. They were followed up for 6 to 72 months. Thirty-one cases had delayed CFR, with an incidence of 21.83%, and occurred between 1 and 5 years postoperatively, with an average of 2.4 years. All 31 patients with delayed CFR underwent endoscopic CFR repair. The nasal endoscopy was rechecked at 2 weeks, 1 month, 3 months and 6 months after operation. Twenty-eight patients were repaired successfully after 1 operation, while 2 patients after 2 operations and 1 patient after 3 operations. These patients were followed up for 6 to 60 months, and no CFR occurred again. Univariate analysis showed that the degree of tumor resection, recurrence, size, texture, postoperative radiotherapy and operator experience were the risk factors of delayed CFR (all P<0.05). Multivariate analysis showed that the degree of tumor resection and recurrence were the highest independent risk factors for postoperative CFR, and tumor size, texture, postoperative radiotherapy and operator experience were the independent risk factors in this study. Conclusions: Delayed CFR after IPA is related to the degree of tumor resection, recurrence, size, texture, postoperative radiotherapy and the operator experience. It is necessary to completely remove the tumor under endoscope, to expand resection of the dura and necrotic tissue around the leak, to repair the defect with multi-layer materials, to follow-up closely and to repair timely after operation.

Abstract
Objective: To indicate the clinical features of endoscopic transnasal resection of epidural cholesteatoma at paracentral skull base and to analyze its efficacy. Methods: The total excision rate, postoperative complications and postoperative curative effect of 7 patients (4 males and 3 females, aging from 32 to 63 years old) who underwent middle skull base surgery for epidural cholesteatoma resection under transnasal endoscope at Tianjin Huanhu Hospital between August 2017 and August 2020 were retrospectively reviewed. All patients were followed up for 6 to 36 months. The postoperative MRI, clinical symptoms and recurrence were reviewed. Descriptive statistical methods were used for analysis. Results: Among the 7 patients, there were total resection (complete resection of cyst contents and capsule) in 4 patients, near-total resection (complete resection of cyst contents, incomplete resection of cyst capsule) in 1 patient, and subtotal resection (incomplete resection of cyst contents and capsule) in 2 patients. The clinical symptoms of all patients were improved postoperatively with 1 patient who had no clinical symptoms. One case had postoperative cerebrospinal fluid rhinorrhea, which was cured after lumbar drainage and nasal iodoform gauge packing. Up to now, 7 patients (including patients with partial resection) had no recurrence. Conclusion: Endoscopic transnasal approaches may be effectively used for resection of epidural cholesteatoma in the paracentral skull base in carefully selected cases.

Abstract
This study was designed to explore if antiviral treatment influences the performance of serum alpha-fetoprotein (AFP) for hepatocellular carcinoma (HCC) among the high-risk chronic HBV-infected patients. A total of 5936 patients who had evidence of chronic HBV infection were enrolled from four independent centres in this retrospective study, including 1721 chronic hepatitis B (CHB), 2286 liver cirrhosis (LC), 798 HCC within Milan criteria and 1131 HCC beyond Milan criteria patients. Stratified by whether they received treatment or not, the patients were further divided into antiviral and non-antiviral groups. Then, the performance of AFP for discriminating HCC was evaluated. Patients receiving antivirals had significantly lower median levels of AFP compared with the non-antiviral patients (P < .001), and there were significantly less patients with abnormal AFP levels in antiviral groups (P < .001). Antiviral therapy improved the AUROCs of AFP for discriminating HCC within Milan criteria. When setting the cut-off values at 20 ng/mL and 100 ng/mL as surveillance and confirmatory tests respectively for HCC among patients receiving antiviral treatment, AFP exhibited a significantly higher sensitivity than those of 200 ng/mL and 400 ng/mL, which are currently recommended by some guidelines, without compromising specificity. Further analysis in antiviral patients revealed that serum AFP had better performance for discriminating HCC within Milan criteria in ALT ≤ 1ULN patients than that in ALT > 1ULN patients. In conclusion, in the era of antiviral therapy, serum AFP's surveillance performance was substantially improved for HCC within Milan criteria among the high-risk population of CHB and LC patients.

Abstract
Background and Objective: Parkinson disease (PD) with rapid eye movement (REM) sleep behavior disorder (PD-RBD) tend to be a distinct phenotype with more severe clinical characteristics and pathological lesion when compared with PD without RBD (PD-nRBD). However, the pathological mechanism underlying PD-RBD remains unclear. We aim to use the resting-state functional magnetic resonance imaging (rs-fMRI) to explore the mechanism of PD-RBD from the perspective of internal connectivity networks. Materials and Methods: A total of 92 PD patients and 20 age and sex matched normal controls (NC) were included. All participants underwent rs-fMRI scan and clinical assessment. According to the RBD screening questionnaire (RBDSQ), PD patients were divided into two groups: PD with probable RBD (PD-pRBD) and PD without probable RBD (PD-npRBD). The whole brain was divided into 90 regions using automated anatomic labeling atlas. Functional network of each subject was constructed according to the correlation of rs-fMRI blood oxygenation level dependent signals in any two brain regions and network metrics were analyzed using graph theory approaches. Network properties among three groups were compared and correlation analysis was made using distinguishing network metrics and RBDSQ scores. Results: We found both PD-pRBD and PD-npRBD patients existed small-world characteristics. PD-pRBD showed a wider range of nodal property changes in neocortex and limbic system than PD-npRBD patients when compared with NC. Besides, PD-pRBD showed significant enhanced nodal efficiency in the bilateral thalamus and betweenness centrality in the left insula, but, reduced betweenness centrality in the right dorsolateral superior frontal gyrus when compared with PD-npRBD. Moreover, nodal efficiency in the bilateral thalamus were positively correlated with RBDSQ scores. Conclusions: Both NC and PD patients displayed small-world properties and indiscriminate global measure but PD-pRBD showed more extensive changes of nodal properties than PD-npRBD. The increased centrality role in the bilateral thalamus and the left insula, and disruption in the right dorsolateral superior frontal gyrus may play as a key role in underlying pathogenesis of PD-RBD.

Abstract
The purpose of this study was to evaluate the use of a three-dimensional half-ring distraction frame for thumb phalangeal lengthening. From February 2009 to March 2015, 23 patients (23 thumbs) with thumb loss were treated with a half-ring distraction frame. Active movements of the metacarpophalangeal (MCP) joint were measured with a goniometer. These measurements were compared with the opposite hand. Differences were considered statistically significant at p<0.05. Clinical outcome was assessed based on the modified Mayo score. Bone union and good alignment were achieved in all patients. The mean distraction time was 44 days (range, 35-62 days). The mean time to union was 20 days (range, 49-86 days). The mean palmar and radial abduction of the thumb was 60° (range, 53°-65°) and 63° (range, 58°-70°), respectively; on the uninjured side, these measurements were 62° (range, 56°-65°) and 64° (range, 60°-73°), respectively (p>0.05). The mean extension-flexion arc of the MCP joint was 46° (range, 40°-50°); the measurement on the uninjured side was 48° (40°-54°) (p>0.05). The mean follow-up period was 51 months (4.25 years) (range, 48-65 months). The mean modified Mayo Score was 138 (range, 113-145). There were 19 excellent, 3 good, and 1 fair results. The half-ring distraction frame is a viable alternative for thumb lengthening as it provides stable, three-dimensional fixation, resulting in good hand function.

Abstract
BACKGROUND The interaction between nonalcoholic fatty liver disease (NAFLD) and chronic hepatitis B infection (CBI) was unclear. We aimed to investigate the association between NAFLD and CBI and the effect of NAFLD on response to antiviral therapy in pediatric population. METHODS All children aged 0-18 years with liver biopsy-proven NAFLD, CBI, and co-existing NAFLD and CBI were consecutively collected. Children with co-existing CBI and NAFLD were considered as cases and n:m matched with simple NAFLD and simple CBI patients in the same cohort, respectively. In longitude study, the role of NAFLD in antiviral response was further analyzed in children with CBI who received antiviral treatment. Logistic or Cox regression models were used appropriately for analysis. RESULTS 765 subjects were finally enrolled with 62 co-existing patients, 560 CBI patients, and 143 NAFLD patients. Multivariate analysis showed that HBV DNA level was negatively associated with NAFLD in CBI children (OR 0.376, 95% CI 0.173-0.818). Conversely, the severity of steatosis and levels of serum lipid profile were found to be inversely associated with CBI in NAFLD subjects. Then, in longitude study, we found that HBsAg loss at 96 weeks of antiviral treatment was independently associated with NAFLD (aHR 3.245, 95% CI 1.288-8.176). CONCLUSIONS An inverse association between CBI and NAFLD reciprocally existed in pediatric population. In longitude study, HBsAg loss was associated with NAFLD at week 96 of antiviral therapy.

Abstract
Objective:To investigate the clinical symptoms and immunology inspection characteristics of nasal cavity local allergy. Method:Selected 60 patients as observation group, who had only nasal local allergy symptoms, allergen skin prick test and serum allergen specific IgE (SIgE) test were negative, 40 allergic rhinitis (AR) patients and 40 healthy volunteers as control groups. To detect Symptom scores and VAS scores, and eosinophilia counts in venous blood, allergen skin prick test (SPT), serum allergen SIgE test, nasal secretions allergen SIgE test, nasal mucous membrane excitation test in both observation group and AR group, eosinophilia counts in nasal secretion, taked the data for statistical analysis.Result:There was no difference (P> 0.05) in the symptom scores and VAS scores of observation group and the AR group. The eosinophilia counts in venous blood in the AR group were higher than in the observation group (P< 0.05). The eosinophilia counts in venous blood in the observation group were higher than in the healthy volunteers group (P< 0.05). The positive rate of nasal secretions dust mites and pollen allergen was 90% (54/60) in observation group. There was no significant difference (P> 0.05) in the eosinophilia percentages in nasal secretion in the observation group and the AR group. There was significant difference (P< 0.05) in the eosinophilia percentages in nasal secretion in the observation group and the healthy volunteers group. There were 6 patients in observation group whose nasal secretions allergen SIgE test and nasal mucous membrane excitation test were both negative, could be diagnosised as non-allergic rhinitis (NAR). According to eosinophilia counts in venous blood and nasal secretions, 4 patients were diagnosised as vasomotor rhinitis and 2 patients were diagnosised as NAR with eosinophilia syndrome. There were 54 patients in observation group whose nasal secretions allergen SIgE test and (or) nasal mucous membrane excitation test were positive, could be diagnosised as local allergic rhinitis. After three years, all of the observation group patients were detected with SPT and serum allergen SIgE test. Five patients diagnosed as local allergic rhinitis before three years were positive. Six patients diagnosed as NAR before three years were negative.Conclusion:For patients with the typical medical history and symptoms of AR, but allergen SPT and serum allergen SIgE test were negative, there was local specific hypersensitivity in nasal mucosa, but the reaction was not accompanied by systemic sensitization. Combined with nasal secretions allergen SIgE test or allergen nasal mucosa proocation tests positive, could be diagnosed as local allergic rhinitis.

Abstract
Objective:The aim of this study is to analyze the safety of a large number cases of percutaneous dilatation tracheostomy. Method: Retrospective analyzed the clinical data of PDT (1 200 cases) and TT (326 cases) patients which were recruited. The postoperative complications were analyzed statistically. PDT and TT randomized controlled trials (PDT and TT) were conducted with 80 cases in each group. The intraoperative conditions (including operative time, intraoperative bleeding volume and incision size) and postoperative complications in the two groups were statistically analyzed. The data were analyzed by SPSS 17.0 software. Result:①Randomized controlled study: The blood loss, incision size and operative time of two groups have significant difference. Comparison of postoperative complications: the number of postoperative bleeding and the total number of complications were statistically significant difference (P<0.05). However, granulation formation, incision infection and subcutaneous emphysema showed no significant difference (P>0.05). ②Large sample study: The postoperative follow-up results showed that there were significant differences in postoperative bleeding, postoperative infection, subcutaneous emphysema and the total number of complications (P<0.05), but there was no significant difference in the formation of tracheal granulation (P>0.05). Conclusion:This study further validates that PDT is a safe method to establish long-term artificial airway through large sample and randomized controlled study, which accords with the direction of modern minimally invasive surgery. PDT not only short operation time, and is easy to grasp, but also safe and reliable. If there is no obvious operation contraindication, we can choose PDT first for critically ill patients who need tracheotomy, and the success rate and safety are high after mastering the operation skills.

Abstract
Abstract
Background: Tamoxifen(TAM), a selective estrogen receptor modulator(SERM), is the most widely used adjuvant endocrine therapy for premenopausal breast cancer patients. Cytochrome P-450(CYP450) enzyme, CYP2D6, is involved in the conversion of tamoxifen to endoxifen which is one of the main active metabolites of tamoxifen in vivo. Variants of CYP2D6 gene may result in a decreased enzyme activity and lead to poor prognosis of the patients. Different from caucasians, the most common polymorphism among Chinese women is allelic variant *10, which generates a 188 C to T transition, resulting in a lower activity of the enzyme. Based on some retrospective studies, tamoxifen-treated patients with the CYP2D6*10 T/T genotype have a worse clinical outcome. Toremifene(TOR), another kind of SERM is not metabolited by CYP2D6 enzyme thus may not be influenced by its polymorphism. We conducted this study to validate the association between CYP2D6*10 genotype and the outcomes of patients receiving TAM and TOR respectively.
Methods: A total of 276 patients with primary early-stage ER-positive breast cancer received adjuvant tamoxifen (n=169) or toremifene (n=107) therapy at Natinal Cancer Center from 2004-2012 were analyzed. All patients had received 5-year endocrine therapy after completion of surgery. TaqMan SNP genotyping assays was performed on CYP2D6*10 from blood samples. The association of CYP2D6 *10 genotype with disease free survival (DFS) and clinicopathological characteristics was analyzed in patients receiving tamoxifen and toremifen.
Results: 32.6% (90 of 276) of the patients were homozygous for wild-type C/C genotype, 47.1% (130 of 276) were heterozygous for C/T genotype, and 20.3% (56 of 276) were homozygous for variant T/T genotype. The frequency of CYP2D6 *10 allele in our study was 43.8%. The 5-year DFS rate for tamoxifen and toremifene treatment group were 81.6% and 83.2% respectively. There was no significant difference of DFS between the two groups(P=0.274). Among 169 patients in tamoxifen group, 5-year DFS rate was considerably lower in patients with homozygous variant T/T genotype than those with wild-type C/C or C/T genotype (73.4% versus 83.2%, P=0.004). And the T/T genotype was found to be a significant prognostic marker for DFS in multivariate analysis (hazard ratio = 4.7; P<0.001) after adjusting for patient's characteristics mentioned above. For the toremifene group, there was no difference of DFS between T/T genotype and the others(P=0.332). For all the 56 homozygous variant T/T genotype patients, patients receiving toremifene treatment had a much higher 5-year DFS rate than those receiving tamoxifen but unfortunately it was not statistically significant (90.0% versus 73.4%, P=0.192).
Conclusions: About one fifth of Chinese breast cancer patients had homozygous T/T genotype which might get less benefit from TAM adjuvant treatment. Toremifene may be a better option for this kind of patients. Further large-scale prospective clinical studies are warranted to validate this concept.

Abstract
BACKGROUND Meta-Analyses are the basis of professional and healthcare agencies recommendations and have a growing importance. Quality of meta-analyses has been investigated in some medical fields but to our best knowledge this issue remains under investigated in orthopedics. Therefore, we performed a systematic analysis to: 1) after the introduction of PRISMA statement as a comprehensive guideline and the use of the AMSTAR tool as the standard for sufficient review methodology, has the quality of MAs improved because of that? 2) have some general characteristics influenced the quality of MAs (country, funding source, number of authors)? MATERIAL AND METHODS We systematically searched the meta-analyses in the top four journals with the impact factor (2015) as following: JBJS, Osteoarthritis Cartilage Arthroscopy and Clin Orthop Relat Res from 2005 to 2008 and from 2012 to 2015. Likewise from 2012-2015, we also analyzed the meta-analyses from OTSR. Characteristics were extracted based on the PRISMA statement and the AMSTAR tool. Country, number of authors, funding source were also extracted. RESULTS A total of 154 meta-analyses were included in the present study. Score with PRISMA statement and the AMSTAR checklist were 20.86±3.04 out of a maximum of 27 and 7.86±1.55 out of a maximum of 11. The best journal was OTSR according to the PRISMA (23.06±1.92) and AMSTAR (9.13±0.87) scores. And the worst journal was Clin Orthop Relat Res according to the PRISMA score (19.4±2.70) and JBJS according to the AMSTAR score (6.78±1.65). Twelve items showed significant difference in the PRISMA statement, and five items in the AMSTAR checklist. Integral score of PRISMA statement and AMSTAR checklist has a significant difference between 2005-2008 and 2012-2015. The MAs reported from U.S. (56, 36.4%) were more than any other region in the world. And the MAs published by Asia/Oceania increased remarkably between these two period times [from (4, 10.8%) to (45, 38.5%)]. CONCLUSION This study showed that methodological reporting quality of meta-analyses in the major orthopedics journals has improved after the publication of the PRISMA statement. LEVEL OF EVIDENCE Level III.

Abstract
43 We consider 'the proposition that the intrinsic binding energy that results from the noncovalent interaction of a specific substrate with the active site of the enzyme is considerably larger than is generally believed. An important part of this binding energy may be utilized to provide the driving force for catalysis, so that the observed binding energy represents only what is left over after this utilization' [Jencks,W.P. (1975) Adv. Enzymol. Relat. Areas. Mol. Biol. , , 219-410]. The large ~12 kcal/mol intrinsic substrate phosphodianion binding energy for reactions catalyzed by triosephosphate isomerase (TIM), orotidine 5'-monophosphate decarboxylase and glycerol-3-phosphate dehydrogenase is divided into 4-6 kcal/mol binding energy that is expressed on the formation of the Michaelis complex in anchoring substrates to the respective enzyme, and 6-8 kcal/mol binding energy that is specifically expressed at the transition state in activating the respective enzymes for catalysis. A structure-based mechanism is described where the dianion binding energy drives a conformational change that activates these enzymes for catalysis. Phosphite dianion plays the active role of holding TIM in a high-energy closed active form, but acts as passive spectator in showing no effect on transition-state structure. The result of studies on mutant enzymes is presented, which support the proposal that the dianion-driven enzyme conformational change plays a role in enhancing the basicity of side chain of E167, the catalytic base, by clamping the base between a pair of hydrophobic side chains. The insight these results provide into the architecture of enzyme active sites and the development of strategies for the de novo design of protein catalysts is discussed.

Abstract
OBJECTIVE This study examines the relationship between intracranial pressure (ICP) changes after skull injury repair and neurocognitive function before and after the repair. PATIENTS AND METHODS Sixty patients undergoing skull injury repair participated in the study. A non-invasive detection analyzer was used to detect the ICP 2 days before operation, 10 days after the operation and one month after the operation in all patients. Additionally, the mean cerebral blood flow velocities (MV) in the internal carotid and the medial cerebral arteries were detected using a transcranial Doppler ultrasound (TCD). The neurological and cognitive functions were assessed using the NIHSS and the MMSE scales, respectively. And finally, an ELISA assay was used to detect the plasma insulin-like growth factor (IGF)-1 and beta-amyloid peptide (Ab) levels. RESULTS The results showed that all parameters studied improved significantly and continuously after surgery. CONCLUSIONS We suggest that the improvement in the ICP values and the neurocognitive functions are related to the resulting decreased expression levels of IGF-1 and Abeta after the repair.

Abstract
Uncoupling protein-2 (UCP2) reduces oxidative stress by facilitating the influx of protons into mitochondrial matrix, thus dissociating mitochondrial oxidation from ATP synthesis. UCP2 is expressed abundantly in brain areas and plays a key role in neuroprotection. Here, we sought to determine if UCP2 deficiency produces cognitive impairment and anxiety in young mice, and to determine if hippocampal UCP2 is essential for the beneficial effects of voluntary exercise. Antisense oligonucleotide (ASO) was used to produce UCP2 knockdown in mice. Our results firstly showed that UCP2-targeted ASO significantly reduced UCP2 mRNA and protein expression in the hippocampus. ASO treatment impaired learning and memory of the mice in Y-maze, T-maze, and object recognition tests (ORT). ASO-treated mice exhibited more anxiously in OPT, light/dark box test, and elevated plus maze (EPM) than the control mice. We also found that wheel running ameliorated cognitive dysfunction and anxiety-like behaviors in ASO-treated mice. Furthermore, voluntary exercise reversed ASO-induced changes in hippocampal levels of serotonin (5-HT), dopamine (DA), and norepinephrine (NE). However, UCP2 protein in the hippocampus was not correlated with cognitive and anxiolytic benefits of exercise. These findings suggest that hippocampal UCP2 is essential for cognitive function and the resistance to anxiety of mice, but not required for the beneficial effects of exercise.

Abstract
Apoptosis is a major mode of cell death occurring during ischemia–reperfusion (I/R) induced injury. The p66Shc adaptor protein, which is mediated by PKCβ, has an essential role in apoptosis under oxidative stress. This study aimed to investigate the role of PKCβ2/p66Shc pathway in intestinal I/R injury. In vivo, ischemia was induced by superior mesenteric artery occlusion in mice. Ruboxistaurin (PKCβ inhibitor) or normal saline was administered before ischemia. Then blood and gut tissues were collected after reperfusion for various measurements. In vitro, Caco-2 cells were challenged with hypoxia–reoxygenation (H/R) to simulate intestinal I/R. Translocation and activation of PKCβ2 were markedly induced in the I/R intestine. Ruboxistaurin significantly attenuated gut damage and decreased the serum levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6). Pharmacological blockade of PKCβ2 suppressed p66Shc overexpression and phosphorylation in the I/R intestine. Gene knockdown of PKCβ2 via small interfering RNA (siRNA) inhibited H/R-induced p66Shc overexpression and phosphorylation in Caco-2 cells. Phorbol 12-myristate 13-acetate (PMA), which stimulates PKCs, induced p66Shc phosphorylation and this was inhibited by ruboxistaurin and PKCβ2 siRNA. Ruboxistaurin attenuated gut oxidative stress after I/R by suppressing the decreased expression of manganese superoxide dismutase (MnSOD), the exhaustion of the glutathione (GSH) system, and the overproduction of malondialdehyde (MDA). As a consequence, ruboxistaurin inhibited intestinal mucosa apoptosis after I/R. Therefore, PKCβ2 inhibition protects mice from gut I/R injury by suppressing the adaptor p66Shc-mediated oxidative stress and subsequent apoptosis. This may represent a novel therapeutic approach for the prevention of intestinal I/R injury.

Abstract
The detection of compensatory mutations that abrogate negative fitness effects of drug-resistance and vaccine-escape mutations indicates the important role of epistatic connectivity in evolution of viruses, especially under the strong selection pressures. Mapping of epistatic connectivity in the form of coordinated substitutions should help to characterize molecular mechanisms shaping viral evolution and provides a tool for the development of novel anti-viral drugs and vaccines. We analyzed coordinated variation among amino acid sites in 370 the hepatitis B virus (HBV) polymerase sequences using Bayesian networks. Among the HBV polymerase domains the spacer domain separating terminal protein from the reverse-transcriptase domain, showed the highest network centrality. Coordinated substitutions preserve the hydrophobicity and charge of Spacer. Maximum likelihood estimates of codon selection showed that Spacer contains the highest number of positively selected sites. Identification of 67% of the domain lacking an ordered structure suggests that Spacer belongs to the class of intrinsically disordered domains and proteins whose crucial functional role in the regulation of transcription, translation and cellular signal transduction has only recently been recognized. Spacer plays a central role in the epistatic network associating substitutions across the HBV genome, including those conferring viral virulence, drug resistance and vaccine escape. The data suggest that Spacer is extensively involved in coordination of HBV evolution.

Abstract
We have found ferromagnetism in epitaxially grown superlattices of CaRuO(3)/CaMnO(3) that arises in one unit cell at the interface. Scanning transmission electron microscopy and electron energy loss spectroscopy indicate that the difference in magnitude of the Mn valence states between the center of the CaMnO(3) layer and the interface region is consistent with double exchange interaction among the Mn ions at the interface. Polarized neutron reflectivity and the CaMnO(3) thickness dependence of the exchange bias field together indicate that the interfacial ferromagnetism is only limited to one unit cell of CaMnO(3) at each interface. The interfacial moment alternates between the 1 μ(B)/interface Mn ion for even CaMnO(3) layers and the 0.5 μ(B)/interface Mn ion for odd CaMnO(3) layers. This modulation, combined with the exchange bias, suggests the presence of a modulating interlayer coupling between neighboring ferromagnetic interfaces via the antiferromagnetic CaMnO(3) layers.

Abstract
Insect haemocytes are known to participate in innate immunity via the phagocytosis of pathogens. However, the function of haemocytes in tissue remodelling is less understood. We report here that haemocytes play roles in fat body degradation by expressing a cysteine proteinase cathepsin L in the lepidopteran Helicoverpa armigera. During metamorphosis, haemocytes undergo morphological changes by increasing their cell size and transforming their granulocytes into macrogranulocytes. The population of haemocytes also changes with increased number of granulocytes and decreased plasmatocytes. The expression level of cathepsin L in haemocytes, mainly in granulocytes and plasmatocytes, increases. The steroid hormone 20-hydroxyecdysone is able to promote the transformation of granulocytes into macrogranulocytes, and up-regulate the expression level of cathepsin L. The knock-down of the cathepsin L gene by RNA interference in haemocytes in vitro results in deficient granulocytes transforming into macrogranulocytes. Haemocytes are able to enter the decomposed fat body during metamorphosis. The over-expression of the proteinase domain C1A of cathepsin L results in cell apoptosis. Haemocytes, especially macrogranulocytes, undergo apoptosis and cathepsin L is released into haemolymph and the fat body during metamorphosis for fat body decomposition and degradation. These results suggest that cathepsin L is related to the transformation of granulocytes to macrogranulocytes to enter the fat body, and induce haemocyte apoptosis for further tissue degradation.

Abstract
Divalproex sodium is an antiepileptic drug. Hepatotoxicity is one of the most common side effects induced by divalproex sodium. Impaired fatty acid metabolism is considered to play an important role in the drug-induced hepatotoxicity. The sterol regulatory element-binding protein 1c (SREBP-1c) and peroxisome proliferator-activated receptor α (PPARα) are two key transcription factors involved, respectively, in fatty acid synthesis and degradation in liver. In the present study, we investigated the hepatotoxicity induced by divalproex sodium and its potential mechanism. The results indicated that divalproex sodium significantly decreased the cell viability and increased lactate dehydrogenase leakage in hepatocytes. The activities of alanine aminotransferase and aspartate transaminase were increased in hepatocytes treated with divalproex sodium. Furthermore, divalproex sodium activated SREBP-1c and increased the mRNA expressions of acetyl-CoA carboxylase 1, fatty acid synthase and stearoyl-CoA desaturase 1. Divalproex sodium also inhibited PPARα and decreased the messenger RNA expressions of 3-hydroxy-3-methylglutaryl-CoA synthase 2 and carnitine palmitoyltransferase 1A. These results suggest that the hepatotoxicity induced by divalproex sodium may be related with fatty acid synthesis and degradation mediated by SREBP-1c and PPARα in hepatocytes.
