ABSTRACT

Melanoma is the most aggressive skin malignant tumor, which is prone to early metastasis and relapse after treatment. Therapeutic tumor vaccines are new immunotherapies, which have the advantages of low toxicity and inhibiting tumor metastasis. Melanoma has a high mutation load and a large number of specific antigens. Currently, various types of tumor vaccines have been developed for melanoma, especially those based on dendritic cells (DC). Although the efficacy of therapeutic DC vaccines in melanoma has been confirmed by a number of studies, these vaccines still have problems such as insufficient immune effect and poor efficacy when used alone, and there is still a large room for improvement. In this paper, the current research status of therapeutic DC vaccines for melanoma was reviewed, and the research key points and optimization strategy of therapeutic DC tumor were prospected.

ABSTRACT

The use of small interfering RNAs (siRNAs) has been under investigation for the treatment of several unmet medical needs, including acute lung injury/acute respiratory distress syndrome (ALI/ARDS) wherein siRNA may be implemented to modify the expression of pro-inflammatory cytokines and chemokines at the mRNA level. The properties such as clear anatomy, accessibility, and relatively low enzyme activity make the lung a good target for local siRNA therapy. However, the translation of siRNA is restricted by the inefficient delivery of siRNA therapeutics to the target cells due to the properties of naked siRNA. Thus, this review will focus on the various delivery systems that can be used and the different barriers that need to be surmounted for the development of stable inhalable siRNA formulations for human use before siRNA therapeutics for ALI/ARDS become available in the clinic.

ABSTRACT

Invasive fungal infections (IFIs) represent a growing public concern for clinicians to manage in many medical settings, with substantial associated morbidities and mortalities. Among many current therapeutic options for the treatment of IFIs, amphotericin B (AmB) is the most frequently used drug. AmB is considered as a first-line drug in the clinic that has strong antifungal activity and less resistance. In this review, we summarized the most promising research efforts on nanocarriers for AmB delivery and highlighted their efficacy and safety for treating IFIs. We have also discussed the mechanism of actions of AmB, rationale for treating IFIs, and recent advances in formulating AmB for clinical use. Finally, this review discusses some practical considerations and provides recommendations for future studies in applying AmB for combating IFIs.

ABSTRACT

Proteins and peptides (PPs) have gradually become more attractive therapeutic molecules than small molecular drugs due to their high selectivity and efficacy, but fewer side effects. Owing to the poor stability and limited permeability through gastrointestinal (GI) tract and epithelia, the therapeutic PPs are usually administered by parenteral route. Given the big demand for oral administration in clinical use, a variety of researches focused on developing new technologies to overcome GI barriers of PPs, such as enteric coating, enzyme inhibitors, permeation enhancers, nanoparticles, as well as intestinal microdevices. Some new technologies have been developed under clinical trials and even on the market. This review summarizes the history, the physiological barriers and the overcoming approaches, current clinical and preclinical technologies, and future prospects of oral delivery of PPs.

ABSTRACT

Objective:To evaluate preoperative serum ferritin (SF) in predicting the prognosis of patients with esophageal squamous cell carcinoma (ESCC).Methods:A retrospective analysis was conducted on 280 ESCC patients undergoing radical resection of esophageal cancer at Zhejiang Cancer Hospital from Jan 2008 to Dec 2013. Univariate and multivariate analysis were used to investigate the relationship between preoperative SF level and patients′ clinicopathologic characteristics. Kaplain-Meier method was used to analyze the relationship between preoperative SF level and the prognosis.Results:There were 183 cases (65.4%) with low SF level and 97cases (34.6%) with high SF level. The 1-, 3-and 5-year survival rates in low SF patients were 78.7%, 50.3%, 43.2% and that in high SF were 69.1%, 35.1%, 32.0%, respectively (χ 2=4.697, P=0.031). Univariate analysis demonstrated that intravascular cancer embolus, nerve infiltration and the level of preoperative SF were related to ESCC patients prognosis (all P<0.05). The multivariate analysis showed that carcinoma cell embolus ( OR=1.662, 95% CI: 1.239-2.229, P=0.001), nerve infiltration ( OR=1.823, 95% CI: 1.361-2.443, P<0.001) and the level of preoperative SF ( OR=1.504, 95% CI: 1.113-2.032, P=0.008) were independent risk factors for ESCC patients prognosis. Conclusion:Preoperative SF level closely associates with the prognosis of ESCC patients.

ABSTRACT

Atherosclerosis (AS) is a lipid-driven chronic inflammatory disease occurring at the arterial subendothelial space. Macrophages play a critical role in the initiation and development of AS. Herein, targeted codelivery of anti-miR 155 and anti-inflammatory baicalein is exploited to polarize macrophages toward M2 phenotype, inhibit inflammation and treat AS. The codelivery system consists of a carrier-free strategy (drug-delivering-drug, DDD), fabricated by loading anti-miR155 on baicalein nanocrystals, named as baicalein nanorods (BNRs), followed by sialic acid coating to target macrophages. The codelivery system, with a diameter of 150 nm, enables efficient intracellular delivery of anti-miR155 and polarizes M1 to M2, while markedly lowers the level of inflammatory factors and . In particular, intracellular fate assay reveals that the codelivery system allows for sustained drug release over time after internalization. Moreover, due to prolonged blood circulation and improved accumulation at the AS plaque, the codelivery system significantly alleviates AS in animal model by increasing the artery lumen diameter, reducing blood pressure, promoting M2 polarization, inhibiting secretion of inflammatory factors and decreasing blood lipids. Taken together, the codelivery could potentially be used to treat vascular inflammation.

ABSTRACT

Liposomes mimic natural cell membranes and have long been investigated as drug carriers due to excellent entrapment capacity, biocompatibility and safety. Despite the success of parenteral liposomes, oral delivery of liposomes is impeded by various barriers such as instability in the gastrointestinal tract, difficulties in crossing biomembranes, and mass production problems. By modulating the compositions of the lipid bilayers and adding polymers or ligands, both the stability and permeability of liposomes can be greatly improved for oral drug delivery. This review provides an overview of the challenges and current approaches toward the oral delivery of liposomes.

ABSTRACT

Objective To analyze the infectious status and genotype characteristics of group A rotavirus (RV) in children with diarrhea in Hangzhou city in 2017, and to provide information for the disease surveillance, epidemic control as well as vaccine development.Methods Fecal samples from children with acute diarrhea at Children's Hospital of Zhejiang University were collected from Jan to Dec in 2017. All samples were tested for RV antigen by emulsion technique. The antigen-positive samples were further detected by reverse transcription polymerase chain reaction (RT-PCR) and sequencing to determine the G and P genotypes. The RV positive rates in different genders, ages and months were compared by chi-square test. Results A total of 20895 fecal samples were collected from 12389 male patients and 8506 female patients. The gender ratio was 1.46:1. In 5012 (23.99%) RV antigen positive samples, 2964 (23.92%) were from male patients and 2048 (24.08%) were from female patients. There was no gender difference in RV positive rate (χ2=0.049, P>0.05). In the study, RV could be detected in the whole year. January, February and December were peak months, and the RV positive rates were significantly different in different months (χ2=2654.681, P<0.05). The highest RV positive rate was in 18-24 months age group and the lowest in<6 months age group, respectively. Children under 2 years old accounted for 76.56%RV positive cases, and those under 5 years old accounted for 98.72% RV positive cases. The RV positive rates were also significantly different in all age groups (χ2=1013.832, P<0.05). A total of 116 samples were selected from each month, following the random stratified sampling principle, for PCR amplification, sequencing, and genotyping according to VP7 (G genotype) and VP4 (P genotype). A total of 4 G genotypes were detected and G9 (85.3%) was the predominant one. In the two detected P genotypes, P[8] (96.6%) was predominant. The 4 G/P combination genotypes were G9P[8] (85.3%), G3P[8] (9.5%), G2P[4] (3.5%), and G1P[8] (1.7%). Conclusions RV was a common pathogen in pediatric patients with acute diarrhea in Hangzhou city in 2017. Children under 5 years old, especially 18 months to 2 years old infants was the main infected population. The study showed RV infection had obvious seasonality and winter was the peak period. The G9 genotype was predominant in G genotypes, P[8] genotype was predominant in P genotypes, and G9P[8] genotype was predominant in G/P combination genotypes, respectively.

ABSTRACT

Objective To compare the efficacy of arterial stenting with that of traditional B -T shunt for neo-natal pulmonary atresia with intact ventricular septum.Methods Twenty -six cases of neonatal pulmonary atresia with intact ventricular septum were treated at Children′s Hospital of Zhengzhou from December 2005 to December 201 5,aged 3 to 23 days[(8.20 ±4.80)days],and weighted 2.80 -3.88 (3.41 ±0.27)kg.Accompanied with pulmonary hypo-plasia,all these patients were combined with PDA and ASD or PFO.Before operation,the peripheral oxygen saturation was kept in 61 % -75%,averaged at 67%.Among them,1 2 cases underwent arterial catheter stenting,and 1 4 cases re-ceived B -T shunt (including modified B -T shunt and central shunt)ductus ligation.After operation,the oxygen satu-ration in these children was observed,and they were examined by echocardiography and true lateral chest X -ray,blood flow situations in stents and shunts were assessed,and follow -up examinations were conducted in 1 ,3,6 and 1 2 months postoperatively.Results Stents were successfully inserted into these 1 2 cases.After traditional pulmonary shunt,pa-tients′peripheral oxygen saturation was (82.73 ±5.59)%,compared with that of patients after arterial catheter sten-ting (86.1 8 ±3.1 9)%,there was significant difference(t =1 0.71 ,P <0.05).In pulmonary shunt group,2 cases died,1 case died of postoperative heart failure,and the other case was complicated with pulmonary infection and died of respiratory failure;in catheter stent group,1 case was complicated with postoperative supraventricular tachycardia and recovered after drug intervention.For the follow -up examinations 1 ,3,6 and 1 2 months after the operation,1 case of B -T shunt in pulmonary shunt group was improved by central shunt due to slow blood flow,less shunt volume,and ox-ygen saturation decreased to 69%.For the catheter stent group,1 case was improved by stent balloon dilatation due to declined peripheral oxygen saturation 2 months postoperatively,and after the operation,transcutaneous oxygen saturation was improved.No patients died in the catheter stent group.Conclusions In traditional B -T shunts,the operation is extensive,and complications are common,and the recovery turns slowly.Arterial catheter stenting can be used as the preferred method of treatment for one -stage surgical pulmonary atresia with intact ventricular septum to reduce the weakness feasibly and effectively.

ABSTRACT

Panax notoginseng (BurK.) F.H.Chen is a traditional Chinese medicinal material with a time-honored history of cultivation.There are a series of problems,such as high pesticide residues,serious disease and pest,and continuous cropping obstacles in the process of the cultivation of notoginseng.Pollution-free cultivation is an effective strategy for the sustainable development of notoginseng industry.We herein summarized three points of the pollution-free cultivation of notoginseng in this review.The standard of lands suitable for the cultivation of notoginseng was established on the basis of the analysis of medicinal plants around global producing areas.The integrated measures of soil improvement were put forward by cfficient rotation and soil disinfection with new varieties breeding combined with the management of water,light and fertilization,and the safe and low-toxic methods of disease and pest control.Additionally,the mode of wild tending should be carried out when the marker-assisted breeding of new varieties was developed,and the platform of comprehensive disease and pest control was founded.Above-mentioned points can effectively perfect and optimize the pollution-free cultivation of notoginseng and promote sustainable development of notoginseng industry.

Methods:MTT assay was adopted to detect the cell growth inhibition. The morphological changes of B16 and A375 cells were observed under an inverted microscope. Nitrite production of activated mouse macrophages induced by lipopolysaccharide ( LPS) plus IFN-γ was measured by Griess assay. Results: Timosaponin AⅢ could significantly inhibit the growth of B16 cells at the concentration of 16 μmol·L-1 after the 48- and 72-hour treatment, and significantly inhibit the growth of A375 cells at the concentration ranged from 4 to 16 μmol·L-1 after the 48-and 72-hour treatment. Shrinkage, vacuoles and necrosis of B16 and A375 cells were observed after the 48-and 72-hour treatment by 16μmol·L-1 timosaponin AⅢ,the other concentration of timosaponin AⅢ showed no notable effect on B16 cells and vacuoles of A375 cells appeared at the concentration from 4 to 16 μmol· L-1. Compared with RAW 264. 7 stimulated LPS plus IFN-γ,timosaponin AⅢ could significant inhibit nitrite production of macro-phage inflammatory cell model at the concentration of 10μmol·L-1(P<0. 01). Conclusion:Timosaponin AⅢcan inhibit the prolif-eration of melanoma B16 and A375 cells and macrophage inflammation,suggesting it has anti-tumor and anti-inflammatory effects . The anti-tumor effect of timosaponin AⅢ may be related to the inhibition of tumor inflammation.
