    As packaging and delivery system combined products, pre-filled syringes (PFS) are becoming increasingly popular in the field of biopharmaceutical products for their own advantages. However, the development of biopharmaceutical products in PFS presents its own distinctive challenges. The components of the PFS are likely to interact with the drug, in particular, issues involving incompatibility with silicone oil which often be used as a lubricant. Silicone oil will migrate into injection to form droplets, which may induce aggregation of protein, resulting the formation of insoluble particles and other issues. Therefore, this paper reviews the development of PFSs, the siliconization technology for PFSs, the insoluble particles caused by silicone oil and the solutions to this matter.

    The aim of the present work was to develop a benzoyl peroxide (BPO)(5%) gel for skin acne vulgaris treatment, and the evaluation of in vitro equivalance to the reference listed drug (RLD), Benzihex? AC, was carried out. The formulations of the gel were formulated by employing Carbopol 980 as hydrophilic matrix and poloxamer 407 as sorbefacient. Optimization of formulation was supported by agar diffusion method and the following factors were investigated through single factor screening at three levels: the partical size of BPO (100-400 mesh number), the concentration of Carbopol 980 (1.0%-2.0%) and poloxamer 407 (0.1%-0.3%). The response variables was the diffusion distance in agar. The optimized gel had similar in vitro release profiles to the RLD based on the similarity factor (f2). The delivery amounts of BPO into and through the pig skin from the optimized gel were compared to those from RLD. Both gels showed consistent behavior: the stratum corneum uptake and skin penetration of BPO from the two gels were generally comparable. Taken together, the results of this research provided a generic BPO gel that was in vitro equivalent to the RLD.

    In this study, a T7 modified redox-sensitive polyamide amine (T7-PEG-SS-PAMAM, T7-PSSP) conjugate with potential for liver cancer targeting was constructed for pyruvate kinase M2 (PKM2)-siRNA delivery. 1H NMR was used to confirm the structural characters of the polymer. The particle size, polydispersity index and ζ potential of the T7-PSSP/siRNA complex were (119.8±0.76)nm, 0.19±0.12 and (8.92±0.38)mV, respectively. The results of agarose gel electrophoresis indicated that the carrier-gene complex had a good stability and could protect siRNA from RNase degradation. Flow cytometry quantitative analysis confirmed that the modification of T7 peptide could significantly increase the uptake of siRNA in HepG2 cells. According to the semi-quantitative analysis results, siRNA was rapidly released from the PSSP/siRNA complex under the action of glutathione reductant, indicating that the PSSP/siRNA complex could efficiently release the delivered siRNA in a reducing environment. Real-time fluorescence quantitative detection results showed that T7-PSSP/siRNA complex displayed the highest PKM2 gene transfection and silencing efficiency compared to the negative control and other complexes groups. The above results showed that this bifunctional siRNA delivery system, T7-PSSP/siRNA complex, had both tumor-targeted and redox-sensitive property, it could effectively release siRNA in the intracellular environment to enhance siRNA knockout effect, and thus could be used as a potential nanocarrier for efficient siRNA delivery.

    The pyritinol hydrochloride osmotic pump tablet cores were prepared with wet granulation method, then followed by coating a layer of ethylcellulose with polyethylene glycol (PEG) 4000 as the plasticizer and porogen. The formulation was optimized by single factor test with the similarity of drug release curves as the index. On the basis of the results of central composite design, the optimal formulation composition of the tablet cores was as follows: pyritinol hydrochloride 150 mg, glucose 6.31 mg, polyvinyl pyrrolidone (PVP) K30 16 mg, and microcrystalline cellulose 27.69 mg, the coating solution was 300 ml of acetone solution containing 9 g of cellulose acetate and 2.1 g of PEG 4000, and the weight gain was 3.85%. The release of pyritinol hydrochloride from the optimal osmotic pump tablets could be described by zero-order kinetics. The in vitro drug release behavior was not affected by pH value of the release medium. The pharmacokinetics in rabbits was carried out with the commercially available pyritinol hydrochloride tablets as the reference preparation. The results showed that the peak concentration of the self-made tablets was lowered and the peak time was extended compared with the reference preparation, indicating the desired experimental purpose was achieved.

    Polyethylene glycol 6000 (PEG 6000), polyvinylpyrrolidone (PVP) K30 and copolyvinylpyrrolidone (coPVP) were respectively used as carriers to prepare solid dispersions (SDs) of rivaroxaban by solvent method, and the dissolution characteristics in vitro were studied. According to the results of single factor test, the optimal preparation of rivaroxaban SDs was as follows: the SDs with coPVP as carriers and drug/carrier ratio of 1∶10 were prepared at 65 ℃ and rotating time of 45 min. Physicochemical properties of the obtained SDs were investigated by differential scanning calorimetry (DSC), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The dissolution of rivaroxabancoPVP SDs at 5 min was 5.2 times as much as the bulk drug and reached 96.8% at 20 min. The results of DSC, XRD and SEM analyses showed that rivaroxaban was highly dispersed in polymer carrier coPVP with amorphous form, which proved the formation of solid dispersion.

    Bezafibrate (BZ) was micronized by gas antisolvent (GAS) process with supercritical CO2 (SCCO2) as an antisolvent, and the needle-like crystallines with ordered structure were obtained. The results showed that smaller microparticles were obtained at higher crystallizing temperature and lower pressure, and meanwhile the length of crystalline decreased as the concentration of BZ decreased. The length of crystalline altered with the kind of solvents, and it did not show significant change with the flow rate of SC-CO2. The crystallines of BZ were analyzed by microscopic imaging system, scanning electron microscopy (SEM), Fourier transform infared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The recrystallization of BZ was successfully performed by GAS and needle-like crystallitns with smaller particle size and a narrow distribution were obtained. The results of FT-IR, XRD, TGA and DSC indicated that there was no significant differences in physicochemical properties between the raw material and particles of BZ micronized by GAS.

    Two PCR methods, PCR-RFLP and real-time PCR with TaqMan probe, were established to determine the origin of hyaluronidase raw material. The DNA of the hyaluronidase was extracted by magnetic beads DNA extraction kit. The extracted DNA was used as a template for PCR-RFLP and TaqMan probe real-time fluorescence PCR to detect whether the sample contains pig, cattle and sheep source ingredients. Both PCR methods were well-characterized and both pig and sheep-derived nucleic acid concentrations of 0.01 ng/μl and cattle-derived nucleic acid concentrations of 0.1 ng/μl were detectable. Furthermore, 0.001 ng/μl pig-derived nucleic acid can be detected using real-time PCR. PCR-RFLP method and TaqMan probe real-time fluorescence PCR method can be used to detect the species origin of biochemical drug. We first reported the identification of species origin of hyaluronidase raw material using molecular identification technology, which is of great significance to control the quality of biochemical drugs.

    Novel erythropoiesis stimulating protein (NESP, also known as Aranesp?) is a complex biopharmaceutical glycoprotein used to treat anemia associated with chronic renal disease clinically. It contains five N-linked carbohydrate chains (Asn24, Asn30, Asn38, Asn83 and Asn88) and one O-glycosylation site up to 22 sialic acid residues. An LC-MS/MS method was established for peptide mass fingerprinting and structural elucidation of NESP. After digested with trypsin, the NESP peptides were separated both with HPLC and zwitterionic type of hydrophilic interaction chromatography (ZIC-HILIC). Compared with HPLC stationary phase, the ZIC-HILIC exhibited better separation efficiency and MS response signal. Pronase E proteolytic enzymes can degrade most of the amide bonds in glycoproteins, while retaining the intact glycans with a small amount of amino acid. In the way, a ZIC-HILIC column was applied to the separation of the Pronase E digested peptides. It was shown that the ZIC-HILIC column had high capability as well as high selectivity for structural recognition of the O-glycopeptides. Finally, three kinds of O-glycopeptides were identified and they displayed nonsialylated, monosialylated and disialylated O-glycans as GalNAcGal(NeuAc)2, GalNAcGal(NeuAc)1 and GalNAcGal.

    A near-infrared spectroscopy (NIR) method was established for the determination of levofloxacin hydrochloride (1) tablets. Fifty laboratory samples were prepared according to the prescription of 1 tablets and 10 batches of industrial samples were collected. A quantitative calibration model was established by NIR combined with partial least square (PLS) regression, taking the contents determined by HPLC as the reference values. The quantitative calibration model of 1 was successively established. The original spectrum of samples were pretreated by FD+VN technology, and the spectra in the ranges of 5 526.7-6 187.5 cm-1, 5 003.6-5 389.1 cm-1, and 4 466.8-4 700.8 cm-1 were chosen for analysis. The R2 and RMSECV of the calibration set were 0.999 4 and 2.29, while that of the validation set were 0.998 2 and 2.43, respectively. The error was -1.23-1.03 mg/g. Furthermore, a paired t-test was performed to confirm that the NIR values and the reference values have no significant difference. The method is simple, rapid, and can be applied to rapid detection of levofloxacin hydrochloride tablets.

    A new polymorph of cariprazine hydrochloride ( named as form Ⅳ) was discovered and investigated. The form Ⅰ and Ⅳ were both characterized by powder X-ray diffraction, differential scanning calorimetry, thermal gravimetric analysis, attenuated total reflectance-fourier transform infrared spectroscopy and scanning electron microscopy. The results showed that form Ⅳ was significantly different from form I. The thermal gravimetric analysis showed that form Ⅳ would transform into form Ⅰ at around 195 ℃. Stress testing suggested that form Ⅳ would transform into form Ⅰ under high humidity condition [R.H. (90±5)%]. The above experimental data showed that form Ⅳ was a metastable crystal form. Metastable crystal form generally has better solubility than its corresponding stable form. Subsequent solubility measurement also verified that form Ⅳ could dissolve more in water than form Ⅰ.
