Fingerprinting vanadium in soils based on speciation characteristics and also isotope arrangements.
The established model adequately characterized the multi-exponential and time-dependent plasma pharmacokinetics, target binding and blood proteasome inhibition of bortezomib. Further, the model was able to accurately predict the impact of a strong CYP3A inducer (rifampicin) and inhibitor (ketoconazole) on bortezomib exposure. In conclusion, the mechanistic PBPK/PD model successfully described the complex pharmacokinetics, target inhibition and DDIs of bortezomib in patients. This study illustrates the importance of incorporating target biology, drug-target interactions and in vitro clearance parameters into mechanistic PBPK/PD models and the utility of such models for pharmacokinetic, pharmacodynamic and DDI predictions.MAO Ze-dong's view on traditional Chinese medicine (TCM) can be divided into the scientific view on TCM, the development view on TCM and the future view on TCM. The core of MAO Ze-dong's view on TCM lies in its scientific nature. The basic content of MAO Ze-dong's development view on TCM includes unity of TCM and Western medicine (WM), advocating the multi-angle development of TCM from the height of Chinese national dignity, independence and self-confidence. MAO Ze-dong's future view on TCM is targeted at WM learning from TCM, combining TCM and WM and establishing new Chinese medicine. The contemporary enlightenment of MAO Ze-dong's view on TCM is to start from reforming the medical education system before establishing new Chinese medicine.OBJECTIVE To evaluate the clinical efficacy and safety of Congrong Shujing Granules ( , CSGs) in treating patients with Parkinson's disease (PD) and Chinese medicine (CM) syndrome of Shen (Kidney) essence deficiency, and to investigate the potential mechanism involving efficacy through a transcriptome sequencing approach. METHODS Eligible PD patients with syndrome of Shen essence defificiency were randomly assigned to a treatment group or a control group by a random number table, and were treated with CSGs combined with Western medicine (WM), or placebo combined with WM, respectively. Both courses of treatment lasted for 12 weeks. The Unifified Parkinson's Disease Rating Scale (UPDRS) score, the PD Question-39 (PDQ-39) score, CM Syndrome Scale score, and drug usage of all patients were evaluated before and after treatment. Safety was evaluated by clinical laboratory tests and electrocardiographs. Blood samples from 6 patients in each group were collected before and after the trial and used for transcriptomic X7B. CONCLUSIONS CSGs combined with WM can be used to treat PD patients with CM syndrome of Shen essence defificiency with a good safety. The possible mechanism of action and relevant gene loci were proposed.

METHODS A total of 146 eligible participants from 3 hospitals in China were randomized into the TNT group (73 cases) and the AT group (73 cases) using a central randomization. Both groups received Western medicine thrice a day for 4 weeks. Moreover, patients in the TNT group received subcutaneous insertion of a thick needle into Shendao (GV 11) acupoint, while patients in the AT group received AT at acupoints of Cuanzhu (BL 2), Yangbai (GB 14), Dicang (ST 4), Xiaguan (ST 7), Jiache (ST 6), Yingxiang (LI 20) and Hegu (LI 4), 4 times a week, for 4 weeks. Both groups received 2 follow-up visits, which were arranged at 1 month and 3 months after treatment, respectively. Epigenetics inhibitor The primary outcome measure was House-Brackmann Facial Nerve Grading System (HBFNGS) grade. And the clinical recovery rates of both groups were evaluated according to the HBFNGS grades after treatment. The secondary outcome measures included the facial disability index (FDI) and electroneurogram (EnoG). The adverse events were observed and recorded in both groups. RESULTS Three cases withdrew from the trial, 2 in the TNT group and 1 in the AT group. There was no signifificant difference in the clinical recovery rates between the TNT and AT groups after 4-week treatment [40.85% (29/71) vs. 34.72% (25/72), P>0.05]. At the 2nd follow-up visit, more patients in the TNT group showed reduced HBFNGS grades than those in the AT group (P0.05). CONCLUSION The clinical effect of TNT was equivalent to that of AT in patients with BP at recovery stage, while the post-treatment effect of TNT was superior to that of AT.

It is proposed to collect the patient's exhalation in a disposable sterile plastic bag, place it in a low-temperature freezer chamber to freeze the water vapor, and then transfer part of the dried exhaled sample to the gas analyzer using a disposable syringe. It is proposed to use ozone purge for 10-15 min to sterilize the gas path. Experimentally, it is shown that the water vapor content in the exhalation samples decreased by ~ 20 times when the packet with samples was kept at a temperature of - 18 °C during 10 min. Cooling the exhalation sample in the packet to - 45 °С and lower will allow reducing the water vapor content at least 200 times from the initial level. A new universal system for collecting and drying of patient exhalation samples for a medical laser photo-acoustic gas analyzer has been developed and tested. A gas path for a medical laser gas analyzer has been designed, which allows sterilization of the internal gas path surfaces using ozone purging.Non-small cell lung cancer (NSCLC) constitutes nearly 85% of all cases of lung cancer. Drug resistance, dose-limiting toxicity, and metastasis in NSCLC eventually reduce the efficacy of chemotherapeutics. In this study, we have shown that the methanol-ethyl acetate partitioned fraction from Magnolia grandiflora L. seeds (MEM) exhibit potential anti-cancer activities against NSCLC H1975 cells in vivo and in vitro. MEM significantly inhibited the proliferation of H1975 cells in a concentration- and time-dependent manner. Further, MEM exhibited potent anti-tumor efficacy and low toxicity in nude mice bearing H1975 tumors. Our study also showed that MEM could induce cellular apoptosis in H1975 cells by down-regulating the protein expression levels of Akt and p-Akt-473, and by increasing the ratio of Bax/Bcl-2. Also, MEM significantly inhibited metastasis-related cell invasion and migration of H1975 cells, which associated with the down-regulation of HIF-1α, MMP-2, and MMP-9 protein expression levels. Thus, our data shows that MEM may be an effective fraction of M.
