To investigate the efficacy of interferon alpha 2 b plus ribavirin combination therapy in sixty-two patients with chronic hepatitis c (CHC) infection originating from a single blood donor. The 62 patients who developed CHC following blood transfusion from a known single infected donor were treated with interferon and ribavirin combination therapy for 48 weeks and followed-up for 96 weeks. The therapy regimen consisted of subcutaneous administration of 3-500 MIU interferon alpha 2 b every other day and daily oral administration of 0.6-1.0 g of ribavirin. Patients were monitored during treatment and in follow-up for sustained virological response (SVR), early virology response (EVR), treatment end virology response (ETVR), biochemical response of withdrawals, and side effects. The SVR rate was 83.9% (52/62). The EVR rate was 95.2% (59/62). The ETVR rate was 87.1% (54/62). The biochemical response rate after withdrawal of treatment was 100.0%. Eight patients developed mildly abnormal thyroid function as a result of the interferon therapy, but all were able to complete the antiviral treatment regimen under the care of endocrinologists. Younger age, relatively short course of disease, low viral load, and better compliance, but not sex, were correlated to curative effect of the combination therapy. Interferon alpha 2 b plus ribavirin combination therapy had a significant curative effect on a group of 62 CHC patients originating from a single case, with 52 of the patients showing SVR out to 96 weeks after therapy. Antiviral treatment is recommended for hepatitis C virus-positive patients to eradicate the virus and prevent disease progression.

The main methods of characterizing the flowability of pharmaceutical powders include repose angle method, HR method, Carr's index method, Jenike flow function method, fractal dimension method, and mass flow rate method, etc. Regarding powders with different flowabilities as the research subject, comprehensive features of pharmaceutical materials were investigated and characterized. The multivariate analysis method was employed to evaluate and analyze flowability values of the tested pharmaceutical materials. Comparing with the method of the mass flow rate, it was feasible to use multivariate analysis method to evaluate the flowability of powders. Simultaneously, the flowability of pharmaceutical materials could be ranked and definitely quantified, and critical values be determined according to the actual production, which has promoted the previous methods dependent only on the single parameter, i.e. repose angle and compression degree methods. A relatively objective standard method of evaluating flowability of powders is formed.

Cell-penetrating peptides are composed of positively-charged amino acids that can mediate molecules or nano-carriers across cell membranes. However, most of the known cell-penetrating peptides have no cell-or tissue-specificity, with affinity to almost all types of cells in internalization. The non-specificity of cell-penetrating peptides is a significant obstacle in the application to targeted delivery of imaging probes and therapeutic agents. Accordingly, many studies focused on selective switching of systemically-delivered inert cell-penetrating peptides into active forms in diseased tissues. Tsien groups introduced the concept of activatable cell-penetrating peptides in 2004. Subsequently, a growing number of similar delivery systems (molecular or nano-sized) have been documented, and the sensitive factors have included enzyme, lower pH, light and exogenous component. In this paper, we make an overview of the development of activatable delivery system in recent years.

ObjectiveTo study the effect of isoflavones from Sojae Semen Praeparatum (ISSP) on lipid metabolism in atherosclerotic mice, and decipher the underlying mechanism via the peroxisome proliferator-activated receptor gamma/liver X receptor alpha/ATP-binding cassette transporter A1 (PPARγ/LXRα/ABCA1) signaling pathway. MethodFifty ApoE-/- mice were randomly assigned into the model group, western medicine (atorvastatin calcium, 3.03 mg·kg-1) group, and low-, medium-, and high-dose ISSP (2.5, 5, 10 mg·kg-1, respectively) groups, with 10 rats in each group. Atherosclerosis model mice were established by bilateral ovariectomy and feeding high-fat diet. Another 10 ApoE-/- mice receiving ovariectomy and high-fat diet were taken as the sham group. Some mice died of postoperative infection, and finally 6 mice were included in each group. One week after operation, each group was administrated with corresponding drugs or equivalent amount of normal saline. After 12 weeks, the levels of triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and non-esterified fatty acids (NEFAs) in serum and liver tissue were measured. The levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in serum were detected by enzyme-linked immunosorbent assay (ELISA). Hematoxylin-eosin (HE) staining and oil red O staining were used for observation of aortic plaque formation and liver lipid deposition. The mRNA and protein levels of PPARγ, LXRα, ABCA1, and ATP-binding cassette transporter G1 (ABCG1) in liver were determined by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot. ResultCompared with the sham group, the modeling of atherosclerosis increased the aortic plaque area (P<0.01), elevated the serum TC, TG, LDL-C, TNF-α, and IL-6 levels (P<0.01), decreased the level of HDL-C (P<0.01), increased the liver index (P<0.05) and the levels of TC, TG, and NEFAs in liver (P<0.01), and caused obvious hepatic fat vacuoles and lipid deposition. In addition, the modeling down-regulated the mRNA levels of PPARγ, LXRα, ABCA1 in liver (P<0.05, P<0.01),and regulated the mRNA and protein levels of ABCG1(P<0.05, P<0.01). Compared with the model group, atorvastatin calcium and middle-, high-dose ISSP reduced the serum TC, TG, LDL-C, TNF-α, and IL-6 levels (P<0.01), decreased the liver index (P<0.01), alleviated the liver fat vacuoles and lipid deposition, and increased the levels of TC, TG, and NEFAs in the liver (P<0.05, P<0.01). Furthermore, they up-regulated the mRNA and protein levels of PPARγ, LXRα, ABCA1, and ABCG1 in the liver (P<0.05, P<0.01). ConclusionISSP may regulate lipid metabolism through PPARγ/LXRα/ABCA1 signaling pathway to down-regulate the expression of inflammatory cytokines in serum and alleviate liver lipid deposition, thereby suppressing the formation of atherosclerotic plaque.

BACKGROUNDGlobally, the proportion of child deaths that occur in the neonatal period remains a high level of 37-41%. Differences of cause in neonate death exist in different regions as well as in different economic development countries. The specific aim of this study was to investigate the causes, characteristics, and differences of death in neonates during hospitalization in the tertiary Neonatal Intensive Care Unit (NICU) of China.
METHODSAll the dead neonates admitted to 26 NICUs were included between January l, 2011, and December 31, 2011. All the data were collected retrospectively from clinical records by a designed questionnaire. Data collected from each NICU were delivered to the leading institution where the results were analyzed.
RESULTSA total of 744 newborns died during the 1-year survey, accounting for 1.2% of all the neonates admitted to 26 NICUs and 37.6% of all the deaths in children under 5 years of age in these hospitals. Preterm neonate death accounted for 59.3% of all the death. The leading causes of death in preterm and term infants were pulmonary disease and infection, respectively. In early neonate period, pulmonary diseases (56.5%) occupied the largest proportion of preterm deaths while infection (27%) and neurologic diseases (22%) were the two main causes of term deaths. In late neonate period, infection was the leading cause of both preterm and term neonate deaths. About two-thirds of neonate death occurred after medical care withdrawal. Of the cases who might survive if receiving continuing treatment, parents' concern about the long-term outcomes was the main reason of medical care withdrawal.
CONCLUSIONSNeonate death still accounts for a high proportion of all the deaths in children under 5 years of age. Our study showed the majority of neonate death occurred in preterm infants. Cause of death varied with the age of death and gestational age. Accurate and prompt evaluation of the long-term outcomes should be carried out to guide the critical decision.
