The integrity of lysosomes is of vital importance to survival of tumor cells. We demonstrated that LW-218, a synthetic flavonoid, induced rapid lysosomal enlargement accompanied with lysosomal membrane permeabilization in hematological malignancy. LW-218-induced lysosomal damage and lysosome-dependent cell death were mediated by cathepsin D, as the lysosomal damage and cell apoptosis could be suppressed by depletion of cathepsin D or lysosome alkalization agents, which can alter the activity of cathepsins. Lysophagy, was initiated for cell self-rescue after LW-218 treatment and correlated with calcium release and nuclei translocation of transcription factor EB. LW-218 treatment enhanced the expression of autophagy-related genes which could be inhibited by intracellular calcium chelator. Sustained exposure to LW-218 exhausted the lysosomal capacity so as to repress the normal autophagy. LW-218-induced enlargement and damage of lysosomes were triggered by abnormal cholesterol deposition on lysosome membrane which caused by interaction between LW-218 and NPC intracellular cholesterol transporter 1. Moreover, LW-218 inhibited the leukemia cell growth

To evaluate the efficacy and safety of huperzine in treating patients with mild cognitive impairment. The randomized controlled trials(RCT) were retrieved from EMbase, Cochrane Library, PubMed, CNKI, Wanfang and VIP. The methodology quality of the included studies was evaluated, and a Meta-analysis was performed using RevMan 5.3 software. A total of nine RCTs were included. The Meta-analysis results showed that compared with placebo, Huperzine significantly increased the scores of memory quotient(MQ) and mini-mental state examination(MMSE). However, there was no statistical difference between oral tablet and capsule. Compared with placebo, huperzine A was superior in the scores of MQ and MMSE. Huperzine is safe with mild side effects. Due to the low quality of original studies, more high-quality studies are needed to verify its efficacy.

Clinical practice guideline on traditional Chinese medicine therapy alone or combined with antibiotics for sepsis is strictly in accordance with the latest diagnostic criteria for sepsis (sepsis-3) for the treatment of septic patients at different stages through syndrome differentiation. At present, the abuse of antibiotics and the prevalence of drug-resistant bacteria are very serious, without effective solutions. Thus, this is the first time to focus on traditional Chinese medicine combined with antibiotics to treat sepsis, in order to minimize the incidence of drug-resistant bacteria. This Guideline tends to systematically analyze the sepsis period, septic shock period as well as different clinical symptoms and traditional Chinese medicine measures for organ dysfunction in the sepsis process. By analyzing and interpreting the Guideline systematically, the clinicians could understand its purpose, significance and core ideas more thoroughly, and grasp the recommended specific interventions as well as their advantages and disadvantages, hoping to better implement the Guideline, provide guidance to clinicians and standardize the treatment of sepsis by traditional Chinese medicine.

This current cross-sectional study investigates the relationship between thyroid hormones and peripheral artery disease (PAD) among euthyroid Chinese population aged 40 years and above. Serum free triiodothyronine (FT3), free thyroxin (FT4), thyroid-stimulating hormone (TSH), and thyroid antibodies were measured. PAD was defined as ankle-brachial index (ABI) < 0.9. There were 91 (2.9%) PAD cases among the 3,148 euthyroid study participants. Participants in the highest quartile of FT3 and free-triiodothyronine-to-free-thyroxin (FT3/FT4 ratio) had a decreased risk of prevalent PAD (multivariate-adjusted odds ratio, 95% confidence interval: 0.32, 0.15-0.62, P for trend = 0.01 and 0.31, 0.13-0.66, P for trend = 0.004, respectively) compared to those in the lowest quartile. To conclude, FT3 levels and the FT3/FT4 ratio was inversely associated with prevalent PAD in euthyroid Chinese population aged 40 years and above.

Organic acids are widely distributed in plants and related products, and participate in a wide range of metabolic pathways (e.g. tricarboxylic acid cycle), showing diverse pharmacological activities. As a widely used Chinese patent medicine, its adverse reactions are often reported. Therefore, we should further clarify the chemical components of Shenfu injection, and prepare strict quality standards to ensure the safety and effectiveness of its clinical use. Shenfu injection is prepared from red ginseng (steamed roots of Panax ginseng) and black prepared lateral roots of Aconitum carmichaelii (Heishunpian) by using modern extraction process, and organic acids are regarded as one of its main components. In current study, a hydrophilic interaction chromatography (HILIC) coupled with mass spectrometric method (HILIC-LC-MS) was developed and validated for the simultaneous determination of 14 organic acids, including cinnamic acid, ferulic acid, 4-hydroxylbenzoic acid, L-(+)-lactic acid, adipic acid, fumaric acid, caffeic acid, succinic acid, maleic acid, malonic acid, D-malic acid, (-)-shikimic acid, D-tartaric acid, and quinic acid in Shenfu injection. Satisfactory retention and separation were achieved for all organic acids on HILIC chromatographic column. Except cinnamic acid (231 μg•L⁻¹), lactic acid (113 μg•L⁻¹) and malonic acid (32.5 μg•L⁻¹), the limit of quantitation for the remaining 11 compounds were less than 10 μg•L⁻¹. D-Malic acid, malonic acid, quinic acid, L-(+)-lactic acid, and cinnamic acid were observed to have higher contents in Shenfu injection (>1.89 mg•L⁻¹), whereas caffeic acid and adipic acid were undetectable in all batches. Above all, the developed method is suitable for the simultaneous determination of organic acids in Shenfu and some other traditional Chinese medicine injections.

Photosynthetic and growth characteristics of Angelica dahurica were studied in order to clarity the relations of photosynthesis, growth and root dry weight, and provide a theoretical basis for its cultivation. Photosynthesis and growth indexes were meas- ured every 25 days. The contents of chlorophyll a, b, a + b, soluble protein and the activities of Hill reaction, Ca(2+)-ATPase, Mg(2+)-ATPase had an increasing trend; They had the highest value in leaf high-speed growth period. Then, they were decreased in root high- speed growth period. The root dry weight showed negative corelation with photosynthetic characteristics indexes except stomatal con- ductance, however, the negative corelation only from net photosynthetic rate and Ca(2+)-ATPase were significant. The vegetative growth period of spring sowing A. dahuricia was divided into three phases: seedling period, leaf high-speed growth period and root high-speed growth period. The root dry weight showed a significantly positive corelation with the root diameter, leaf dry weight, shoot dry weight, aboveground dry weight. There was the competitive relation between aboveground and underground, so underground growth could be es- timated from leaf area and shoot dimeter.

OBJECTIVETo detect absorbed bioactive compounds of the water extract whose pharmacodynamic effect was craniocerebral protection for quality control assessment.

METHODSAnthraquinones in water extract of rhubarb (WER), in cerebrospinal fluid (CSF) of patients with traumatic brain injury (TBI) and in ipsilateral cortex of TBI rats following oral WER were respectively explored by ultra performance liquid chromatography with photodiode array detector (UPLC-PDA) method developed in the present study. The effects of anthraquinones absorbed into injured cortex on superoxidase dismutase (SOD) activity in TBI rats were detected. The antioxidative anthraquinones absorbed into target organ were evaluated for quality control of WER.

RESULTSAnthraquinones in WER were aloe-emodin, rhein, emodin, chrysophanol, and physcion. Only the last anthraquinone was found in CSF and in ipsilateral cortex under this chromatographic condition. Physcion increased SOD activity in TBI rats significantly.

CONCLUSIONSPhyscion was the main active compound of rhubarb against craniocerebral injury via antioxidant pathway. According to our strategy, the exploration of physcion suggested the possibility of a novel quality control of WER in treating TBI injury.
