Objective: To analyze the occurrence of recompensation conditions in patients with chronic hepatitis B virus-related decompensated cirrhosis after entecavir antiviral therapy. Methods: Patients with hepatitis B virus-related decompensated cirrhosis with ascites as the initial manifestation were prospectively enrolled. Patients who received entecavir treatment for 120 weeks and were followed up every 24 weeks (including clinical endpoint events, hematological and imaging indicators, and others) were calculated for recompensation rates according to the Baveno VII criteria. Measurement data were compared using the Student t-test or Mann-Whitney U test between groups. Categorical data were compared by the χ (2) test or Fisher's exact probability method between groups. Results: 283 of the 320 enrolled cases completed the 120-week follow-up, and 92.2% (261/283) achieved a virological response (HBV DNA 20 IU/ml). Child-Pugh and MELD scores were significantly improved after treatment (8.33 ± 1.90 vs. 5.77 ± 1.37, t = 12.70, P < 0.001; 13.37 ± 4.44 vs. 10.45 ± 4.58, t = 5.963, P < 0.001). During the 120-week follow-up period, 14 cases died, two received liver transplants, 19 developed hepatocellular cancer, 11 developed gastroesophageal variceal bleeding, and four developed hepatic encephalopathy. 60.4% (171/283) (no decompensation events occurred for 12 months) and 56.2% (159/283) (no decompensation events occurred for 12 months and improved liver function) of the patients had achieved clinical recompensation within 120 weeks. Patients with baseline MELD scores > 15 after active antiviral therapy achieved higher recompensation than patients with baseline MELD scores ≤15 [50/74 (67.6%) vs. 109/209 (52.2%), χ (2) = 5.275, P = 0.029]. Conclusion: Antiviral therapy can significantly improve the prognosis of patients with hepatitis B virus-related decompensated cirrhosis. The majority of patients (56.2%) had achieved recompensation. Patients with severe disease did not have a lower probability of recompensation at baseline than other patients.

Glioblastoma(GBM)is a lethal cancer with limited therapeutic options.Dendritic cell(DC)-based cancer vaccines provide a promising approach for GBM treatment.Clinical studies suggest that other immu-notherapeutic agents may be combined with DC vaccines to further enhance antitumor activity.Here,we report a GBM case with combination immunotherapy consisting of DC vaccines,anti-programmed death-1(anti-PD-1)and poly I:C as well as the chemotherapeutic agent cyclophosphamide that was integrated with standard chemoradiation therapy,and the patient remained disease-free for 69 months.The patient received DC vaccines loaded with multiple forms of tumor antigens,including mRNA-tumor associated antigens(TAA),mRNA-neoantigens,and hypochlorous acid(HOCl)-oxidized tumor lysates.Furthermore,mRNA-TAAAs were modified with a novel TriVac technology that fuses TAAs with a destabilization domain and inserts TAAs into full-length lysosomal associated membrane protein-1 to enhance major histo-compatibility complex(MHC)class Ⅰ and Ⅱ antigen presentation.The treatment consisted of 42 DC cancer vaccine infusions,26 anti-PD-1 antibody nivolumab administrations and 126 poly I:C injections for DC infusions.The patient also received 28 doses of cyclophosphamide for depletion of regulatory T cells.No immunotherapy-related adverse events were observed during the treatment.Robust antitumor CD4+and CD8+T-cell responses were detected.The patient remains free of disease progression.This is the first case report on the combination of the above three agents to treat glioblastoma patients.Our results suggest that integrated combination immunotherapy is safe and feasible for long-term treatment in this patient.A large-scale trial to validate these findings is warranted.

Objective To understand the disease burden of patients with advanced schistosomiasis in Jiangsu Province. Methods Totally 450 patients with advanced schistosomiasis from southern, northern and central Jiangsu were chosen by the stratified sampling method, and surveyed by the self-designed economic burden questionnaire in 2015. The economic burden of the patients was analyzed by the descriptive analysis method, and its determinants were explored by the multiple linear regression analysis. Results A total of 450 subjects were surveyed and 434 valid questionnaires were recovered with the recovery rate of 96.44%. The per capita economic burden of advanced schistosomiasis patients was 10 217 Yuan in Jiangsu Province in 2015, including 7 221 Yuan in direct economic burden and 2 996 Yuan in indirect economic burden. The average lost labor force time was 140 days for the patients, and was 23 days for the family. The multiple linear regression analysis showed that the marital status, hospitalization health service utilization, and self-reported health score impacted on the disease economic burden. Conclusion The disease burden of patients with advanced schistosomiasis in Jiangsu Province is heavy.

Tianma(the tuber of Gastrodia eleta) is a widely used and pricy Chinese herb. Its counterfeits are often found in herbal markets, which are the plant materials with similar macroscopic characteristics of Tianma. Moreover, the prices of Winter Tianma(cultivated Tianma) and Spring Tianma(mostly wild Tianma) have significant difference. However, it is difficult to identify the true or false, good or bad quality of Tianma samples. Thus, a total of 48 Tianma samples with different characteristics(including Winter Tianma, Spring Tianma, slice, powder, etc.) and 9 plant species 10 samples of Tianma counterfeits were collected and analyzed by HPLC-DAD-MS techniques. After optimizing the procedure of sample preparation, chromatographic and mass-spectral conditions, the HPLC chromatograms of all those samples were collected and compared. The similarities and Fisher discriminant analysis were further conducted between the HPLC chromatograms of Tianma and counterfeit, Winter Tianma and Spring Tianma. The results showed the HPLC chromatograms of 48 Tianma samples were similar at the correlation coefficient more than 0.848(n=48). Their mean chromatogram was simulated and used as Tianma HPLC fingerprint. There were 11 common peaks on the HPLC chromatograms of Tianma, in which 6 main peaks were chosen as characteristic peaks and identified as gastrodin, p-hydroxybenzyl alcohol, parishin A, parishin B, parishin C, parishin E, respectively by comparison of the retention time, UV and MS data with those of standard chemical compounds. All the six chemical compounds are bioactive in Tianma. However, the HPLC chromatograms of the 10 counterfeit samples were significantly different from Tianma fingerprint. The correlation coefficients between HPLC fingerprints of Tianma with the HPLC chromatograms of counterfeits were less than 0.042 and the characteristic peaks were not observed on the HPLC chromatograms of these counterfeit samples. It indicated the true or false Tianma can be identified by either the similarity or characteristic peaks on HPLC fingerprint. Comparing the Winter Tianma with Spring Tianma showed that the HPLC chromatograms of 15 winter Tianma samples and 11 spring Tianma samples were similar at the mean correlation coefficient of 0.908. But the intensity of the characteristic peaks were different between the two groups of Tianma samples, i.e. the intensity of gastrodin, paishin A and C in winter Tianma was lower than those in spring Tianma. The Winter Tianma and Spring Tianma could be discriminated by either the Fisher unstandardized discrimination function or Linear discriminant function, based on the peak areas of 11 common peaks on HPLC chromatograms as variate.

OBJECTIVETo investigate the effect of the non-PLC-dependent protein kinase C (PKC) pathway of parathyroid hormone (PTH) on the apoptosis and proliferation of osteoblast MC-3T3E1 cells.

METHODSMC-3T3E1 cells were seeded in 96-well plates at the density of 1.5×10(4) cells/mL and incubated for 3 day. The cells were then exposed to 100 nmol/L of [Gly(1), Arg(19)]hPTH(1-28), 100 nmol/L of [Gly(1), Arg(19)]hPTH(1-34), 100 nmol/L of [Gly(1), Arg(19)]hPTH(1-34)+1 µmol/L Go6983, 1 µmol/L Go6983, or deionized water (control) for 1, 24 or 48 h. After the treatments, cell counting kit-8 (CCK-8) and Caspase-Glo® 3/7 Assay (Caspase-3) were used to examine the proliferation and apoptosis of MC3T3-E1 cells.

RESULTSCCK-8 results showed that hPTH(1-34) increased the number of MC3T3-E1 cells compared with hPTH(1-34)+Go6983 at 1 h and 24 h, but this difference was not statistically different. At 48 h, treatment with hPTH(1-34), as compared with hPTH(1-28), significantly increased the number of MC3T3-E1 cells (P<0.05), and this effect was blocked by the PKC inhibitor Go6983 (P<0.05). hPTH(1-34) did not result in significant inhibition of MC3T3-E1 cell apoptosis at 1 h and 24 h as compared with hPTH(1-34)+Go6983, but significantly inhibited the cell apoptosis as compared with hPTH(1-28) (P<0.05); this inhibitory effect was blocked by Go6983 (P<0.05).

CONCLUSIONs A relatively long time (for 48 h) of exposure to PTH can inhibit apoptosis and promote the proliferation of MC3T3-E1cells through a non-PLC-dependent PKC pathway.

OBJECTIVETo establish a new method for detection of red blood cell osmotic fragility by using flow cytometry.

METHODSThe hypotension salt solution of different concentrations (0.70 ml normal saline+0.3 ml deionized water, 0.60 ml normal saline+0.40 ml deionized water and 0.55 ml normal saline+0.45 ml deionized water) were prepared with normal saline and deionized water, in which the red blood cells were suspended, and the residual red blood cells were detected by flow cytometer.

RESULTSThere was no significant difference in percentage of residual red blood cells between different time points detected by flow cytometer in 3 different hypotonic salt solutions. The percentage of residual red blood cells in B+C+D+E+F+G detected time region was different among 3 NaCl dilution groups. The percentage of residual red blood cells in normal control was lower than that in hemoglobinopathy group. The percentage of residual red blood cells in hereditary spherocytosis (HS) group was obviously lower than that in hemoglobinopathy and normal control groups. The comparison of 3 different dilution concentrations found that the second concentration (0.60 ml normal saline+0.40 ml deionized water) is more suitable to screen HS by FC500 flow cytometer.

CONCLUSIONThe detection of red cell osmotic fragility by using flow cytometry is a simple, rapid, objective and economic way that can be an effective screening method for diagnose the HS.

The osmotic pressure of ammonium sulfate solutions has been measured by the well-established freezing point osmometry in dilute solutions and we recently reported air humidity osmometry in a much wider range of concentration. Air humidity osmometry cross-validated the theoretical calculations of osmotic pressure based on the Pitzer model at high concentrations by two one-sided test (TOST) of equivalence with multiple testing corrections, where no other experimental method could serve as a reference for comparison. Although more strict equivalence criteria were established between the measurements of freezing point osmometry and the calculations based on the Pitzer model at low concentration, air humidity osmometry is the only currently available osmometry applicable to high concentration, serves as an economic addition to standard osmometry.

OBJECTIVETo investigate the effects of polysaccharide fraction of Cordyceps sinensis (PSCS) on triptolide (TPL)-induced apoptosis in the HL-60 cells and the involved molecular mechanism.

METHODSThe cultured leukemia HL-60 cells were divided into three groups: control group, TPL group (cells were treated with 5 ng/ml TPL only), and PSCS+TPL cells group (cells treated with 5 ng/ml TPL and 100 microg/ml or 200 microg/ml PSCS for 18 h). Cell viability was tested by MTT assay and apoptotic cells were quantitatively measured by flow cytometry with Annexin V/PI double stain.The expressions of Caspase-3, 6, 7, 9 and NF-kappa B proteins were tested by Western blot.

RESULTMTT assay showed that different concentrations of PSCS inhibited the cell viability. Flow cytometry indicated that TPL markedly increased the apoptosis rate of the HL-60 cells, and PSCS enhanced the apoptosis in a dose-dependent manner. Western blot showed that TPL did not inhibit the expression of the Caspase-3, 6, 7, 9 and NF-kappa B proteins, and when cells were treated with PSCS, the expression of proteins decreased with the PSCS concentration rising.

CONCLUSIONPSCS can enhance TPL-induced apoptosis in HL-60 cells and inhibit the expression of NF-kappa B and Caspase 3,6,7,9,which might be the possible signaling pathway of inducing apoptosis.
