The development of printing ink is a challenge for binder jetting 3D printed preparations, which directly determines the quality of the printed product. This study adopted a 2³ full-factor Design of Experiment (DoE) with three central points to optimize the printing ink composition of levetiracetam 3D printed dispersible tablet based on the concept of Quality by Design. Firstly, using polyvinyl pyrrolidone K30, glycerin and polysorbate 20 as independent variables based on 40% (v/v) isopropanol aqueous solution, and weight variation, hardness, friability and dispersion uniformity of the printed tablets were used as dependent variables. Then obtained the design space of the printing ink prescription by DoE model analysis, and the response optimizer was used to obtain the optimal printing ink prescription: isopropanol aqueous solution containing 0.1% (w/w) polyvinyl pyrrolidone K30 and 4.0% (w/w) glycerin. The jetting mechanism and wettability of the printing ink were analyzed, and different strengths of personalized 3D printed tablets were prepared and characterized, which verified the rationality of the printing ink formulation. This study provided a reference for the development of printing ink for binder jetting 3D printed preparations.

Objective To study the different expressions of receptor activator of nuclear factor-kappa B ligang(RANKL) mRNA in spleens of rats fed with diet of low calcium and high fluoride. Methods A 2× 2×2 factorial design was used and the factors were calcium, fluoride and action time. In the design, 40 Wistar rats [average body mass(118.9±13.5)g] were divided into four groups randomly by weight: control with normal diet (0.790%, calcium), low calcium group with low calcium intake(0.063%, calcium), high fluoride group with normal diet and high fluoride intake(100 mg/L, fluoride) and low calcium and high fluoride group with low calcium and high fluoride intake. After 4 and 8 months, 5 rats of each group were sacrificed and total RNA was extracted from spleen. And the expression levels of RANKL mRNA were determined by reverse transcription polymerase chain reaction (RT-PCR). Results At time of 4 months, the expression level of RANKL mRNA was 0.13± 0.05,0.13± 0.03,0.17±0.02,0.27± 0.05 and at time of 8 months, it was 0.11 ± 0.01,0.16 ± 0.02,0.16± 0.03,0.36 ± 0.07 in control group, low calcium group, high fluoride group, low calcium with high fluoride group, repectively. The factorial design AVONA showed that low calcium and high fluoride had significant effects on RANKL mRNA expression(F = 40.224,56.679, all P < 0.05) while action time had not(F = 2.850, P > 0.05 ). The interactions of low calcium with high fluoride or high fluoride with action time were signifieant(F = 7.247, 18.789, all P < 0.05) while the interaction of high fluoride with action time was not(F = 1.751, P > 0.05). Conclusions Low calcium alone or high fluoride alone or low calcium with high fluoride or low calcium with action time can increase the the RANKL mRNA expression level. High fluoride does not affect the RANKL mRNA level as the action time is prolonged.

Objective Acute kidney injury (AKI) frequently occurs after catheter-based interventional procedures and increases mortality. How-ever, the implications of AKI before thoracic endovascular aneurysm repair (TEVAR) of type B acute aortic dissection (AAD) remain un-clear. This study evaluated the incidence, predictors, and in-hospital outcomes of AKI before TEVAR in patients with type B AAD. Meth-ods Between 2009 and 2013, 76 patients were retrospectively evaluated who received TEVAR for type B AAD within 36 h from symptom onset. The patients were classified into no-AKI vs. AKI groups, and the severity of AKI was further staged according to kidney disease:im-proving global outcomes criteria before TEVAR. Results The incidence of preoperative AKI was 36.8%. In-hospital complications was significantly higher in patients with preoperative AKI compared with no-AKI (50.0%vs. 4.2%, respectively;P<0.001), including acute renal failure (21.4%vs. 0, respectively;P<0.001), and they increased with severity of AKI (P<0.001). The maximum levels of body tem-perature and white blood cell count were significantly related to maximum serum creatinine level before TEVAR. Multivariate analysis showed that systolic blood pressure on admission (OR:1.023;95%CI:1.003–1.044;P=0.0238) and bilateral renal artery involvement (OR:19.076;95%CI:1.914–190.164;P=0.0120) were strong predictors of preoperative AKI. Conclusions Preoperative AKI frequently oc-curred in patients with type B AAD, and correlated with higher in-hospital complications and enhanced inflammatory reaction. Systolic blood pressure on admission and bilateral renal artery involvement were major risk factors for AKI before TEVAR.

Abatract:Objective To study the relationship of the processes of chronic hepatitis B infection with the degree of depression and the level of serum Brain-derived neurotrophic factor (BDNF).Methods 126 patients with different processes of CHB infection were divided into 3 groups,which were asymptomatic HBV carriers (ASC group),liver cirrhosis (LC group)and hepatic cell carcinoma (HCC group).40 healthy volunteers were selected as normal control.Questionnaire was used to study demographic data and the degree of depression was assessed by using Hamilton Depression Rating Scale (HAMD-17).The levels of the serum BDNF were detected by ELISA.Results The ratio of divorced or widowed in LC and HCC groups was higher than that of the control (χ2 = 6.354,11.972;P < 0.01).Severity of depression in ASC,LC and HCC groups was higher than that of the control (χ2 = 16.151,42.150,49.636;P <0.01).Severity of depression in ASC and LC group was lower than that of HCC group (χ2 = 14.345,28.772;P <0.01).The role of BDNF (x ±s,ng/ml)in ASC,LC,HCC and control group were 11.10±3.26,8.66 ± 3.11,7.39 ±2.52 and 12.18±2.59.The levels of serum BDNF in LC and HCC group was lower than ASC group and the control (P <0.01).The process of CHB infection had positive correlation with the score of HAMD (r=0.719,P <0.01),but had negative correlation with thelevels of serum BDNF (r=-0.504,P <0.01). There was negative correlation relationship between the score of HAMD and the levels of serum BDNF (r=-0.526,P <0.01).Conclusion The process of CHB infection can obviously aggravate the degree of depression,and reduce the levels of BDNF gradually.The levels of serum BDNF can be suggested as a psychological laboratory reference basis for the CHB pa-tients with depression.It is expected to improve the level of clinical diagnosis and treatment in CHB with depression.

Syndrome and formulae (or prescription) are two key issues in traditional Chinese medicine (TCM) and the premise research for material basis of TCM. However, vagueness of syndromes and complexity of formulae greatly limited the evaluation to syndromes and effective substance basis of prescription. Therefore, how to solve the evaluation of syndromes, confirming the efficacy material basis in prescription are the current hot issues of international concern. To solve these problems, establishing chinmedomics by integrated serum pharmacochemistry of TCM with metabolomics technology, that is a unique method of TCM research, made outstanding contributions in solving international concerns such as the effectiveness and security aspects of TCM. On the basis of the biological characterization of syndrome, the metabolic profiling of animal models of TCM syndrome, and related metabolic fingerprints as well as metabolic biomarkers were established to evaluate the overall effects of TCM formulae and corresponding relationship of syndrome-formulae. The active constituents were screened using the plotting of correlation between (endogenous) marker metabolites and (exogenous) serum constituents (PCMS), and is ongoing verification by further biological experiments. Correlation analysis between the ingredients in the body after oral formulae and endogenous markers in vivo can be used to clarify the active ingredients and synergistic properties. This method was successfully applied for rapid discovery of potentially bioactive components and metabolites from TCM, and through a series of studies on the chinmedomics, it proved that the established method could help to explore the effective substance for further research of TCM. As a new research approach, Chinmedomics is the best method to fit the holistic concept of TCM, and it can not only interpret the essence of syndrome but also elucidate the scientific connotation of Chinese medical formulae.
