A series of sulfonic functionalized ionic liquids (SFILs) with different acidity were designed and preparedfor the synthesis of terpene esters (e.g. geranyl acetate). The effect of acidity of SFILs on their performancewas investigated systematically. It is found that tuning the acidity of SFILs to an appropriate value resultsin not only high conversion of geraniol but also superior selectivity of geranyl acetate. The SFILs can beeasily separated from products byfiltration under room temperature, thus showing good reusability. Furthermore, the kinetics for SFILs in the esterification of geraniol were determined as the basis for futureprocess design.

Objective: This work aimed to evaluate the safety and clinical efficacy of transcatheter arterial chemoembolization (TACE) combined with c-arm cone-beam CT guided synchronous radiofrequency ablation (RFA) in treatment of large hepatocellular carcinoma (HCC). Methods: 21 patients with large HCC were studied from January 2010 to March 2012. TACE combined with synchronous C-arm cone-beam CT guided RFA were performed on a total of 25 lesions. Conventional imaging examination (CEUS, enhanced CT or MRI) and AFP detection were regularly conducted to evaluate the technical success rate of combined treatment, complications, treatment response, time without disease recurrence and survival rate. Results: The technical success rate of combined treatment was 100%, without any significant complication. After 1 month, there were 19 cases with complete response and 2 cases with partial response, with an complete response rate of 90.4% (19/21) and a clinical effective rate of 100% (21/21). The complete response rates of single nodular lesions (100%, 17/17) was significantly higher than that of multiple nodular lesions (50%, 2/4) (P<0. 05). During 2 to 28 months of follow-up, in 19 cases with complete response, the average time without disease recurrence was $10.8{\pm}6$ months. The total survival rates of 6, 12 and 18 months in 21 patients were 100%, respectively. Conclusion: TACE combined with synchronous C-arm CT guided RFA is safe and effective for treatment of large HCC. The treatment efficacy for single nodular lesion is better than that for multiple nodular lesions.

Twenty natural compounds isolated fromtraditional Chinese medicines were examined for theirantiviral activities against PCV2 in vitro. Antiviral activitywas analyzed by the assays of blocking of virus entry,inhibition of virus replication and inactivation of virusparticles in the virus suspension. 50% cytotoxic concentration(CC50) and 50% effective concentration (EC50) for eachcompound were determined by using the MTT method andimmunofluorescence assay (IFA), respectively. The resultsobtained from the inhibition of virus replication andinactivation of virus particles showed that the maximuminhibition rates for matrine and scutellarin were 57 and72.69% and their SI were 29.87 and 18.66, respectively. However, the results from the assays of inhibition of virusentry and inhibition of virus replication demonstrated thatboth aesculetin and arecoline hydrochloride stimulatedPCV2 replication, with the maximum stimulation rate of387.3 and 219.4%. In summary, both matrine and scutellarinhad antiviral activity against PCV2, while aesculetin andarecoline hydrochloride promoted PCV2 infection replicationin vitro.

Currently, preliminary results have confirmed the existence of receptor-interacting protein kinase 3 (RIPK3) and mixed lineage kinase domain-like protein (MLKL)-dependent necroptosis of pancreatic acinar cells during early acute pancreatitis (AP), which might be a potential target for the effective regulation of necroinflammatory injury. However, the exact effect of receptor-interacting protein kinase 1 (RIPK1)-dependent regulated acinar cell necrosis on AP is still uncertain. In our study, we first explored the changes in the degree of local and systemic inflammation in AP rats when the activation of acinar cell RIPK1 was inhibited. The RIPK1 inhibitor Nec-1 was used to treat rats, and the levels of related inflammatory markers, necrosis indicators and apoptotic indicators were measured. Changes in pancreatic nuclear factor κB (NF-κB) and aquaporin 8 (AQP8) expression were noted. Next, the expression of AQP8 in AR42J cells was inhibited, and the degree of cell necrosis and inflammatory damage was found to be significantly reduced. Most importantly, we demonstrated that the RIPK1/NF-ĸB/AQP8 axis might be a potential regulatory pathway mediating RIPK1-dependent regulated acinar cell necrosis in early AP. Finally, we used the NF-κB inhibitor PDTC and Nec-1 to treat rats in different groups and measured the degree of pathological pancreatic injury, the activation of RIPK1, and the expression of NF-κB and AQP8. In summary, we hypothesized that there might be a RIPK1/NF-ĸB/AQP8 pathway controlling RIPK1-dependent regulated necrosis of acinar cells in AP, which might be a promising therapeutic target against AP-related injury.

Purpose: Cutaneous lymphocyte-associated antigen (CLA)-expressing CD8+T cells have been known to play an important role in the pathogenesis of atopic dermatitis(AD). However, the mechanisms underlying the loss of self-tolerance remainunclear. Regulatory T cells (Tregs) play a key role in the development of homeostasisin the immune system. We, therefore, hypothesized that a reduced ability of Tregs to inhibit autologous CD8+CLA+T cells might be underlying mechanism in AD. Materials and Methods: CD8+CLA+T cells and Tregs were obtained from the peripheral blood of AD patients and control volunteers. The frequenciesof CD8+CLA+T cells were evaluated. The proliferative responses of CD8+CLA+T cells were assessed by flow cytometry, and the levels of transforming growth factor-β1 (TGF-β1) and interleukin-10 (IL-10) in culture supernatants were detected by enzyme-linked immunosorbent assay. Results: Our results revealed higher frequency and increased expression of perforin and granzyme-B in peripheralCD8+CLA+T cells in AD, and lower inhibitory ability of Tregs on proliferation of CD8+CLA+T cells in AD. Meanwhile, the levels of TGF-β1 produced by Tregs were significantly lower in AD, and anti-TGF-β1 abolished such suppression. Conclusion: The attenuated inhibitory ability of Tregs on hyper-activated autologousCD8+CLA+T cells, mediated by TGF-β1, plays an important role in the pathogenesis of AD.

A large proportion of patients with thyroid nodules in China undergo thyroidectomy in order to get confirmatory histology diagnosis. The financial impact of this modality remains to be investigated. To evaluate rationality of performing thyroidectomy without a routine FNA preoperatively from the economic perspective, we conducted a retrospective, observational study of all archival thyroidectomies with records of cost per stay (CPS), cost per day (CPD) and length of stay (LOS) from 2008 to 2013 in the First Affiliated Hospital of Nanjing Medical University. We compared all the parameters between cancer and non-cancer thyroidectomies. We recruited 6, 140 thyroidectomies with valid records of CPS, CPD and LOS in this period. The CPS of cancer thyroidectomy was significantly higher than non-cancer thyroidectomy. The percentage of cancer thyroidectomy increased from 26.5% to 41.6%. The percentage of annual cost of cancer thyroidectomies rose from 30.2% to 45.2%. The LOS for cancer and non-cancer thyroidectomy decreased while the CPD increased in the past six years. The estimated national cost in 2012 for all thyroidectomies would be USD 1.86 billion with USD 1.09 billion for non-cancer thyroidectomies. We have witnessed great improvement in the healthcare for patients with thyroid nodules in China. However, given limited healthcare resources, currently thyroid FNA for more precise preoperative diagnosis may help to curb the rapidly increasing demand in healthcare costs in the future for nodular thyroid disease in China.

By using high-performance liquid chromatography-photodiode array detection, a simple and accurate chromatographic fingerprint method was developed for the identification of Radix Codonopsis (roots of Codonopsis) from different sources. Eighteen herbs of Codonopsis at different habitats in China, including roots from Codonopsis pilosula, Codonopsis pilosula var. modesta and Codonopsis tangshen were analyzed by the fingerprint. The amount of lobetyolin was calibrated, which was found to be more consistent in roots of Codonopsis pilosula as compared to that of Codonopsis pilosula var. modesta and Codonopsis tangshen. Having the fingerprint results, hierarchical clustering analyses were performed to classify the eighteen herbs into three groups: Codonopsis pilosula, Codonopsis pilosula var. modesta and Codonopsis tangshen. This clustering analysis agrees very well with the pharmacognostic identification result, and which could be used as a tool in the quality control of Radix Codonopsis.
