Information on processing methods for alkaloid-rich herbal medicines was collected from classic books of herbal medicine, PhD and MSc dissertations, online scientific databases including PubMed, SciFinder, Scopus, Web of Science, Baidu Scholar and Google Scholar. This paper should help to advance our knowledge of the processing mechanisms and aid in the development of processing methods for alkaloid-rich Chinese herbal medicines.
SC-E3 is a polyherbal formula that contains five medicinal herbs used frequently in traditional herbal medicine. In our previous study, we demonstrated the antioxidant and anti-inflammatory effects of SC-E3. The present study examined the effects of SC-E3 in a mouse model of type-II collagen-induced arthritis (CIA).

In vivo, male DBA/1J mice were immunized by intradermal injection of bovine type-II collagen and complete or incomplete Freund's adjuvant, to induce arthritis. SC-E3 was orally administered daily for 23days. In vitro, bone marrow-derived macrophages (BMMs) were treated with macrophage colony-stimulating factor (M-CSF) and receptor activator of nuclear factor-κB ligand (RANKL) in the absence or presence of SC-E3.

Administrations of SC-E3 were found to have anti-arthritic effects in the joints of CIA mice, as evidenced by reduced paw swelling, bone erosion and deformation, inflammatory cell infiltration, and inflammation in synovial membrane. SC-E3 also reduced serum levels of tumor necrosis factor-α, interleukin-1β, aspartate aminotransferase and alanine aminotransferase. Furthermore, tartrate-resistant acid phosphatase-positive osteoclast numbers in the joints were significantly lower in SC-E3-treated CIA mice than in CIA mice. In addition, the differentiations of BMMs to multinucleated osteoclasts induced by M-CSF and RANKL stimulation were dose-dependently reduced by SC-E3.

These results suggest that SC-E3 possesses substantial anti-arthritic activity because it inhibits pro-inflammatory cytokines and osteoclastogenesis, and that SC-E3 has potential therapeutic use for the treatment of rheumatoid arthritis.

Pancreatic ductal adenocarcinoma (PDAC) has the worst prognosis of all malignant tumors due to unavailable screening methods, late diagnosis with a low proportion of resectable tumors and resistance to systemic treatment. Complete tumor resection remains the cornerstone of modern multimodal strategies aiming at long-term survival. This study was performed to investigate the overall rate of long-term survival (LTS) and its contributing factors.

This was a retrospective single-center analysis of consecutive patients undergoing pancreaticoduodenectomy (PD) for PDAC between 2007 and 2014 at the St. Josef Hospital, Ruhr University Bochum, Germany. Clinical and laboratory parameters were assessed and evaluated for prediction of LTS with Cox regression analysis.

The overall rate of LTS after PD for PDAC was 20.4% (34/167). Median survival was 24 months regardless of adjuvant treatment. Carbohydrate antigen 19-9 levels, tumor grade, lymph vessel invasion, perineural invasion and reduced general condition were significantly associated with LTS in univariate analysis (P<0.05). Serum levels of carbohydrate antigen 19-9, American Joint Committee on Cancer stage, tumor grade, abdominal pain, male, exocrine pancreatic insufficiency and duration of postoperative hospital stay were independent predictors of cancer survival in multivariable analysis.

Cancer related characteristics are associated with LTS in multimodally treated patients after curative PDAC surgery.

The Barcelona Clinic Liver Cancer (BCLC) system has been endorsed by international guidelines as a staging algorithm of hepatocellular carcinoma. This analysis was performed to assess the outcome of liver transplantation in patients treated against the BCLC recommendations.

The data of 198 patients who underwent liver transplantation for hepatocellular carcinoma were extracted from a prospectively maintained database to classify the patients according to the BCLC system.

BCLC staging was as follows 0, n=5; A, n=77; B, n=41; C, n=53; and D, n=22. Accordingly, liver transplantation was performed in the majority of patients against BCLC recommendations. Surgery (n=16), radiofrequency ablation (n=15) and transarterial chemoembolization (n=151) preceded liver transplantation in 182 patients. Sixteen patients were transplanted without pretreatment. The1-, 5- and 10-year survival rates were 83.8%, 62.4% and 45.9%, and 1-, 5-, and 10-year recurrence rates were 7.7%, 22.7% and 26.7%. The BCLC classification did neither impact survival (P=0.796) nor recurrence (P=0.693). In the Cox analysis, RECIST tumor progression and initial alpha fetoprotein were independent predictors of outcome.

Neither the oncological nor the functional stratification imposed by the BCLC system was of importance for outcome. Lack of flexibility and disregard of biological parameters hamper its clinical applicability in liver transplantation.

Liver fibrosis is a hallmark determinant of morbidity in biliary atresia (BA) even in successfully operated cases. Responsible factors for this rapid progression of fibrosis are not completely defined. Aberrant expression of the transcription factor SOX9 and hepatic progenitor cells (HPCs) proliferation have roles in fibrogenesis in cholestatic disorders. However, they were not investigated sufficiently in BA. We aimed to delineate the relation of SOX9 and HPCs to fibrosis and its progression in BA.

Forty-eight patients with BA who underwent an initial diagnostic liver biopsy (LB) and consequent intraoperative LB were recruited and compared to 28 cases with non-BA cholestasis that had an LB in their diagnostic workup. this website Liver fibrosis, tissue SOX9 and HPC expressions were studied in both BA and non-BA-cholestasis cases. Liver fibrosis, SOX9, and HPCs' dynamic changes in BA cases were assessed. Relation of fibrosis and its progression to SOX9 and HPCs in BA was assessed.

SOX9 and HPCs in ductular reaction (DR) form were expressed in 100% of BA and their grades increased significantly in the second biopsy. The rapidly progressive fibrosis in BA, represented by fibrosis grade of the intraoperative LB, correlated significantly to SOX9-DR and HPC-DR at the diagnostic (r=0.420, P=0.003 and r=0.405, P=0.004, respectively) and the intraoperative (r=0.460, P=0.001 and r=0.467, P=0.001, respectively) biopsy. On the other hand, fibrosis, SOX9-DR, and HPC-DR were significantly lower in non-BA cases at a comparable age (P<0.001, P=0.006, and P=0.014, respectively).

Fibrosis in BA is rapidly progressive within a short time and is significantly correlated to SOX9 and HPCs. Assessment of targeting SOX9 and HPCs on fibrosis progression is warranted.

Considering the evolving diagnostic criteria of polycythemia vera (PV), we analyzed the utility of serum erythropoietin (EPO) as a predictive marker for differentiating polycythemia vera (PV) from other etiologies of erythrocytosis.

We conducted a retrospective study after a review of electronical medical records from January 2005 to December 2016 with diagnosis of erythrocytosis using International Classification of Disease-specific codes. To evaluate the diagnostic performance of EPO levels and JAK2-V617F mutation, we constructed a receiver-operated characteristic curve of sensitivity versus 1-specificity for serum EPO levels and JAK2-V617F mutation as predictive markers for differentiating PV from other causes of erythrocytosis.

We surveyed 577 patients with erythrocytosis. Median patient age was 59.2 years, 57.72% (n= 329) were male, 86.3% (n= 491) were white, and only 3.3% (n= 19) were African American. A total of 80.88% (n= 351) of those diagnosed with PV had a JAK2-V617F mutation compared to only 1.47% (n= 2) whose primary diagnosis was secondary polycythemia. When comparing JAK2-V617 mutation to the EPO level, the area under the curve of JAK2-V617 (0.8970) was statistically larger than that of EPO test (0.6765). Therefore, the PV diagnostic methodology using JAK2-V617 is better than the EPO test. An EPO level of< 2 mIU/mL was > 99% specific to predict PV but was only 12% sensitive.

In the appropriate clinical setting, cytogenetic and molecular studies such as JAK2 mutation status prevail as the most useful tools for PV case identification. The use of isolated EPO to screen patients with erythrocytosis is not a good diagnostic approach.

Anti-interleukin-5 (IL-5) therapy has been proposed as a novel treatment option for patients with chronic obstructive pulmonary disease (COPD). However, its efficacy for preventing COPD exacerbation remains unclear.

A literature review was conducted to August 26th 2019. Only randomized controlled trials (RCTs) that investigated the clinical efficacy and adverse effects of anti-IL-5 therapy were included in the meta-analysis. The primary outcome was the risk of COPD exacerbation.

A total of 3 articles containing 5 RCTs were included in the study. Overall, 2837 and 1442 patients received anti-IL-5 therapy (mepolizumab, n=865; benralizumab, n=1972) and placebo, respectively. In the pooled analysis, anti-IL-5 therapy was associated with a lower risk of COPD exacerbation compared with the placebo (rate ratio, 0.92; 95% CI, 0.86-0.97, I
=0%). In addition, no significant differences in the changes in SGRQ scores and FEV
from baseline were found between the anti-IL-5 therapy and placebo (SGRQ, mean difference, -0.86, 95% CI, -1.92 - 0.19, I
=0%; FEV
, mean difference, 0.01, 95% CI, -0.01 - 0.03, I
=0%). Anti-IL-5 therapy had a similar risk of any adverse event (risk ratio, 1.02; 95% CI, 0.99-1.05), an event leading to treatment discontinuation (risk ratio, 1.04; 95% CI, 0.72-1.48) and any serious adverse events (risk ratio, 0.93; 95% CI, 0.85-1.01) when compared with the placebo.

Anti-IL-5 therapy was associated with a lower rate of COPD exacerbation compared with placebo. In addition, anti-IL-5 therapy was well tolerated for COPD patients.

Human herpesvirus type 8 (HHV-8) can be transmitted through unprotected sex as HIV. We aimed to investigate the seroincidence of HHV-8 and associated factors among people living with HIV (PLWH).

From 2014 to 2018, blood samples of PLWH on the first date of HIV care were determined for antibodies against HHV-8. Individuals testing HHV-8-seronegative at baseline were followed for at least four months to estimate the annual seroconversion rate. To identify the factors associated with HHV-8 seroconversion, we compared the clinical characteristics between seroconverters and non-seroconverters who were matched for observation duration.

The HHV-8 seroprevalence increased from 8.1% in 2014 to 20.0% in 2018. HHV-8 seroconversion occurred in 154 (14.7%) PLWH after a total of 2652.16 person-years of follow-up (PYFU), resulting in an overall incidence rate of 5.62 per 100 PYFU, which increased from 3.20 to 6.84 per 100 PYFU during the study period. HHV-8 seroconverters were less likely to have chronic hepatitis B virus (HBV) infection (1.
