BACKGROUND Imiquimod is an imidazoquinoline, which class of compounds are known to have antiviral and antitumoural properties. In recent studies, it was shown that imiquimod modulates the T helper cell type Th1/Th2 response by inducing the production of Th1 cytokines like IFN-gamma, and by inhibiting the Th2 cytokines like interleukin (IL)-4. Several(More)
During the last decade, using versatile, promising, and fascinating mesoporous silica nanoparticles (MSNs) as site-specific and stimuli-responsive drug delivery systems (DDSs) has received concentrated research interest. As one of the most attractive surface modification units, peptides have inherent bioactivity, biodegradability and biocompatibility.(More)
In this work, a matrix metalloproteinase (MMP)-triggered tumor targeted mesoporous silica nanoparticle (MSN) is designed to realize near-infrared (NIR) photothermal-responsive drug release and combined chemo/photothermal tumor therapy. Indocyanine green (ICG) and doxorubicin (DOX) are both loaded in the MSN modified with thermal-cleavable gatekeeper(More)
AIM To describe survival trends in patients in Northeast China diagnosed as gastric cancer. METHODS A review of all inpatient and outpatient records of gastric cancer patients was conducted in the First Affiliated Hospital of China Medical University. All the gastric cancer patients who satisfied the inclusion criteria from January 1, 1980 through(More)
BACKGROUND Human cytomegalovirus (HCMV) is a leading cause of morbidity and mortality in immunocompromised individuals. The unique long b' (ULB') region of HCMV contains at least 19 open reading frames (ORFs); however, little is known about the function of UL145 and UL136. We characterized UL145 and UL136 in low-passage clinical isolates from Chinese(More)
AIM To determine the relationship between host immunity and the characteristics of viral infection or nucleoside analogues (NAs) themselves in patients with chronic hepatitis B (CHB) receiving NA therapy. METHODS Fifty-two hepatitis B envelope antigen (HBeAg) positive CHB patients were enrolled and divided equally into two groups. One group received(More)
OBJECTIVE To research the structure of the unique gene UL148 of the human cytomegalovirus (HCMV) clinical strain in Guangzhou, analyze the relation between its structure polymorphism and HCMV congenital infection, investigate the function of its expression products, and try to reveal the pathogenic mechanism of the gene in HCMV infection in newborns.

Mesoporous silica nanoparticles (MSNs) have proved to be an effective carrier for controlled drug release and can be functionalized easily for use as stimuli-responsive vehicles. Here, a novel intelligent drug-delivery system (DDS), camptothecin (CPT)-loaded and doxorubicin (DOX)-conjugated MSN (CPT@MSN-hyd-DOX), is reported via a facile one-pot preparation(More)
In the wireless sensor network (WSN), the operation reliability is usually evaluated by processing measured datas at network nodes. As the traditional algorithms exist the problems of the complex calculation and large energy consumption, a method for fault diagnosis of nodes in WSN based on rough set theory (RS) and support vector machine (SVM) is proposed(More)
In this paper, a novel stepwise-acid-active multifunctional mesoporous silica nanoparticle (MSN-(SA)TAT&(DMA)K11) was developed as a drug carrier. The MSN-(SA)TAT&(DMA)K11 is able to reverse its surface charge from negative to positive in the mildly acidic tumor extracellular environment. Then, the fast endo/lysosomal escape and subsequent nucleus targeting(More)
