Objectives: This study aimed to present the Asia-Pacific consensus on long-term and sequential therapy for osteoporosis, offering evidence-based recommendations for the effective management of this chronic condition.The primary focus is on achieving optimal fracture prevention through a comprehensive, individualized approach. Methods: A panel of experts convened to develop consensus statements by synthesizing the current literature and leveraging clinical expertise. The review encompassed long-term anti-osteoporosis medication goals, first-line treatments for individuals at very high fracture risk, and the strategic integration of anabolic and anti resorptive agents in sequential therapy approaches. Results: The panelists reached a consensus on 12 statements. Key recommendations included advocating for anabolic agents as the first-line treatment for individuals at very high fracture risk and transitioning to anti resorptive agents following the completion of anabolic therapy. Anabolic therapy remains an option for in dividuals experiencing new fractures or persistent high fracture risk despite antiresorptive treatment. In cases of inadequate response, the consensus recommended considering a switch to more potent medications. The consensus also addressed the management of medication-related complications, proposing alternatives instead of discontinuation of treatment. Conclusions This consensus provides a comprehensive, cost-effective strategy for fracture prevention with an emphasis on shared decision-making and the incorporation of country-specific case management systems, such as fracture liaison services. It serves as a valuable guide for healthcare professionals in the Asia-Pacific region, contributing to the ongoing evolution of osteoporosis management.

Objective To investigate the clinical effect of percutaneous transhepatic drainage combined with sequential percutaneous nephroscopy for necrosectomy and drainage in the treatment of refractory liver abscess after transcatheter arterial embolization (TACE). Methods A retrospective analysis was performed for three patients with refractory liver abscess after TACE in The Affiliated 3201 Hospital of Xi'an Jiaotong University School of Medicine from January 2018 to December 2020, and among the three patients, one had the formation of liver abscess after TACE for hepatic metastases after pancreaticoduodenectomy, one had liver abscess after repeated TACE for massive hepatocellular carcinoma, and one had secondary liver abscess after TACE for traumatic hepatic rupture. All three patients received percutaneous transhepatic drainage and sequential percutaneous nephroscopy for the treatment of refractory liver abscess, and their specific treatment process was summarized. Results All three patients were diagnosed with refractory liver abscess based on CT, routine blood test, procalcitonin, blood culture, and clinical manifestation. Percutaneous transhepatic catheterization under the guidance of conventional ultrasonography or CT and effective antibiotics had an unsatisfactory therapeutic effect, and after sequential percutaneous nephroscopy was performed for necrosectomy and drainage, liver abscess was cured and the patients had good prognosis. Conclusion For refractory liver abscess after TACE, when routine puncture treatment has an unsatisfactory therapeutic effect or a patient cannot tolerate surgical operation, percutaneous transhepatic drainage combined with sequential percutaneous nephroscopy is safe and effective in the treatment of refractory liver abscess.

Objective To investigate the clinical effect of two-step percutaneous transhepatic choledochoscopic lithotomy (PTCSL) in the treatment of complex hepatolithiasis. Methods A retrospective analysis was performed for the clinical data of 118 patients with complex hepatolithiasis who were admitted to 3201 Hospital of Xi'an Jiaotong University Health Science Center from January 2018 to June 2020, and according to the surgical procedure, they were divided into PTCSL group with 60 patients and surgery group with 58 patients. All patients were followed up for half a year to 3 years via telephone and outpatient service. The two groups were compared in terms of general information, perioperative indicators (including time of operation, intraoperative blood loss, incision length, time to first flatus and time to first defecation after surgery, time to extraction of abdominal drainage tube, and length of hospital stay), changes in liver function and inflammatory indicators, postoperative complications (bile leakage, acute cholangitis, wound infection, and venous thrombosis of lower extremities), stone clearance rate and recurrence rate, and quality of life. The two-independent-samples t -test was used for comparison of continuous data between two groups; the paired t -test was used for comparison between different periods of time within group; the chi-square test was used for comparison of categorical data between two groups. Results Compared with the surgery group, the PTCSL group had significantly shorter time of operation, time to first flatus and time to first defecation after surgery, and time to extraction of abdominal drainage tube, a significantly lower intraoperative blood loss, and a significantly shorter incision length (all P < 0.05). On day 1 after surgery, both groups had significant reductions in alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ( P < 0.05) and a significant increase in white blood cell count (WBC) ( P < 0.05), and the PTCSL group had significantly lower levels of ALT, AST, and WBC than the surgery group (all P < 0.05). Compared with the surgery group, the PTCSL group had significantly lower incidence rates of postoperative bile leakage (5.0% vs 17.2%, P < 0.05), acute cholangitis (3.3% vs 13.8%, P < 0.05), wound infection (1.7% vs 10.3%, P < 0.05), and venous thrombosis of lower extremities (1.7% vs 12.1%, P < 0.05). Compared with the surgery group, the PTCSL group had a significantly higher stone clearance rate (58.3% vs 37.9%, P < 0.05) and a significantly lower long-term stone recurrence rate (10.0% vs 20.7%, P < 0.05). The PTCSL group had significantly higher quality of life scores than the surgery group (all P < 0.05). Conclusion For the treatment of complex hepatolithiasis, two-step PTCSL can effectively remove stones, with the advantages of fast postoperative recovery, low recurrence rate and incidence rate of complications, and high quality of life, and therefore, it is an effective alternative surgical procedure.

Objective The aim of this study was to analyze the HCV seroprevalence in the general population visiting the Second Affiliated Hospital of Kunming Medical University. Methods Between January 2013 and December 2015, a total of 160, 239 subjects were screened for the presence of anti-HCV antibodies in blood serum. Anti-HCV antibodies in serum samples were detected by enzyme-linked immunosorbent assay (ELISA) . The results of anti-HCV were analyzed in the features of year, sex and age. Results The HCV seroprevalence in the general population from 2013 to 2015 was 1.11% , 1.04% and 0.91% , respectively, which was significantly higher in men than in women (1.30% vs. 0.91%,P＜0.05) . The highest HCV seroprevalence occurred in aged 31-65 years. Conclusions The analysis of the data suggests that the features of HCV-positive including year, sex and age could be beneficial for formulating scientific strategy and intervention measures of HCV infection and liver cirrhosis, liver failure and hepatocellular carcinoma caused by HCV in Kunming.

Aim To investigate the neuroprotective effects of puerarin on H2O2-induced SH-SY5Y cell ap-optosis and the molecular mechanisms underlying the neuroprotective effects. Methods Neuron injury mod-el was established in vitro through H2O2-induced SH-SY5Y injury. MTT assay was performed to detect the effect of puerarin on H2O2-induced SH-SY5Y survival rates. Hoechst 33342 staining was used to observe the cell apoptosis. JC-1 staining was employed to detect the level of mitochondria membrane poential. Caspase-3 was determined by caspase-3 catalyze the substrate specificity Ac-DEVD-pNA. Caspase-9 was determined by caspase-9 catalyze the substrate specificity Ac-LE-HD-pNA. The effects of puerarin on the protein level of Bcl-2,Bax,p-Akt and Akt were determined by West-ern blot. Results The cell survival rate significantly increased after puerarin pretreatment compared with H2O2model group. Furthermore, puerarin pretreat-ment not only inhibited the decreasing of mitochondrial membrane potential,increasing of caspase-3, caspase-9 enzymatic activity and the expression of Bax,but also promoted the expression of p-Akt and Bcl-2, which was prevented by LY294002, an inhibitor of PI3K/Akt. Conclusion Puerarin can play a neuroprotective role for SH-SY5Y cell apoptosis induced by H2O2, maybe via activating PI3K/Akt signaling pathway.

Background: Vascular resistance and flow rate during hypothermic machine perfusion (HMP) of kidneys is correlated with graft function. We aimed to determine the effects of increasing HMP pressure versus maintaining the initial pressure on kidney transplantation outcomes. Methods: We retrospectively reviewed the data of 76 primary transplantation patients who received HMP-preserved kidneys from 48 donors after cardiac death between September 1, 2013, and August 31, 2015. HMP pressure was increased from 30 to 40 mmHg (1 mmHg = 0.133 kPa) in kidneys with poor flow and/or vascular resistance (increased pressure [IP] group; 36 patients); otherwise, the initial pressure was maintained (constant pressure group; 40 patients). Finally, the clinical characteristics and transplantation outcomes in both groups were assessed. Results: Delayed graft function (DGF) incidence, 1-year allograft, patient survival, kidney function recovery time, and serum creatinine level on day 30 were similar in both groups, with improved flow and resistance in the IP group. Among patients with DGF, kidney function recovery time and DGF duration were ameliorated in the IP group. Multivariate logistic regression analysis revealed that donor hypertension (odds ratio [OR]: 1.43, 95% confidence interval [CI]: 1.02-2.06, P = 0.035), donor terminal serum creatinine (OR: 1.27, 95% CI: 1.06-1.62, P = 0.023), warm ischemic time (OR: 3.45, 95% CI: 1.97-6.37, P = 0.002), and terminal resistance (OR: 3.12, 95% CI: 1.76-6.09, P = 0.012) were independent predictors of DGF. Cox proportional hazards analysis showed that terminal resistance (hazard ratio: 2.06, 95% CI: 1.32-5.16, P = 0.032) significantly affected graft survival. Conclusion Increased HMP pressure improves graft perfusion but does not affect DGF incidence or 1-year graft survival.

BACKGROUNDHow to evaluate the quality of donation after cardiac death (DCD) kidneys has become a critical problem in kidney transplantation in China. Hence, the aim of this study was to develop a simple donor risk score model to evaluate the quality of DCD kidneys before DCD.

METHODSA total of 543 qualified kidneys were randomized in a 2:1 manner to create the development and validation cohorts. The donor variables in the development cohort were considered as candidate univariate predictors of delayed graft function (DGF). Multivariate logistic regression was then used to identify independent predictors of DGF with P < 0.05. Date from validation cohort were used to validate the donor scoring model.

RESULTSBased on the odds ratios, eight identified variables were assigned a weighted integer; the sum of the integer was the total risk score for each kidney. The donor risk score, ranging from 0 to 28, demonstrated good discriminative power with a C-statistic of 0.790. Similar results were obtained from validation cohort with C-statistic of 0.783. Based on the obtained frequencies of DGF in relation to different risk scores, we formed four risk categories of increasing severity (scores 0-4, 5-9, 10-14, and 15-28).

CONCLUSIONSThe scoring model might be a good noninvasive tool for assessing the quality of DCD kidneys before donation and potentially useful for physicians to make optimal decisions about donor organ offers.

OBJECTIVETo evaluate the therapeutic efficacy and safety of liver transplantation for patients with cholangiocarcinoma.

METHODSAccording to the requirements of Cochrane systematic review, a thorough literature search was performed in Pubmed/Medline, Embase and Cochrane Central Register electronic databases ranged between 1995 and 2009 in terms of the key words "liver transplantation", and "cholangiocarcinoma" or "cholangiocellular carcinoma" or "bile duct cancer". And restricted the articles published in the English language. Two reviewers independently screened the studies for eligibility, evaluated the quality and extracted the data from the eligible studies with confirmation by cross-checking. Data were processed for a meta-analysis by Stata 10 software with 1-, 3-, 5-year survival rates and incidence of complications.

RESULTSA total of 14 clinical trials containing 605 patients were finally enrolled in this study. The overall 1-, 3-, 5-year pooled survival rates were 73% (95%CI: 0.65 - 0.80), 42% (95%CI: 0.33 - 0.51) and 39% (95%CI: 0.28 - 0.51), respectively. Of note, preoperative adjuvant therapies (OLT-PAT group) rendered the transplanted individuals comparably favorable outcomes with 1-, 3-, 5-year pooled survival rates of 83% (95%CI: 0.57 - 0.98), 57% (95%CI: 0.18 - 0.92) and 65% (95%CI: 0.40 - 0.87), respectively. In addition, the overall pooled incidence of complications was 62% (95%CI: 0.44 - 0.78), among which that of OLT-PAT group (58%, 95%CI: 0.20 - 0.92) was relatively acceptable compared to those of liver transplantation alone (61%, 95%CI: 0.33 - 0.85) and liver transplantation with extended bile duct resection (78%, 95%CI: 0.55 - 0.94).

CONCLUSIONSIn comparison to curative resection of cholangiocarcinoma with the 5-year survival rate reported from 20% to 40%, the role of liver transplantation alone is so limited, but neoadjuvant radiochemotherapy combined with liver transplantation can bring better short- and long-term prognosis.

OBJECTIVETo globally compare the gene expression profiles during the capillary morphogenesis of human microvascular endothelial cells (HMVECs) in an in vitro angiogenesis system with Affymetrix oligonucleotide array.

METHODSA microcarrier-based in vitro angiogenesis system was developed, in which endothelial cells (ECs) migrated into the matrix, proliferated, and formed capillary sprouts. The sprouts elongated, branched and formed network. The total RNA samples from the HMVECs at the selected time points (0.5 h, 24 h, and 72 h) during the capillary morphogenesis were used for microarray analyses, and the data were processed with the software provided by the manufactory. The expression patterns of some genes were validated and confirmed by Semi-quantitative RT-PCR. The regulated genes were grouped based on their molecular functions and expression patterns, and among them the expression of chemokines/chemokine receptors were specially examined and their functional implications were analyzed.

RESULTSAbout 1500 genes were found up- or down- regulated 2-folds or above detected by the arrays, and among them, about 400 genes regulated 3-folds or above. The regulated genes could be grouped into categories based on their molecular functions such as growth factor and receptor, cell proliferation, extracellular matrix, cell cycle and apoptosis, signaling molecule and transcription factor, and so on, using the Gene Ontology Mining Tool in The NetAffx Analysis Center. The regulated genes were also clustered into six groups based on their patterns of expression. As for chemokines, the CCL2/MCP-1, CCL5/RANTES and CX3CL1 were identified to be specially upregulated at 24 h time point when the sprouting characterized the morphological change. It was thus suggested that they might exert crucial roles at the early stage of angiogenesis.

CONCLUSIONSBased on our angiogenesis model, and by oligonucleotide arrays, the present study demonstrates global profiles of the gene expression during endothelial capillary morphogenesis, and the results provide us much information about the molecular mechanisms of angiogenesis, with which further evaluation of individual genes can be encouraged.
