To identify the active constituents in vitro and blood-absorbed ingredients in vivo from Yin Chen Hao decoction provides scientific evidence for probing its prevention and treatment mechanism on acute liver injury. An ultrahigh performance liquid chromatography quadrupole-time of flight-mass spectrometry (UPLC-QTOF/MS) method was applied for analysis of Yin Chen Hao decoction and the serum samples of mice with con-A induced acute liver injury after preventive oral administration for 14 days (the use of all laboratory animals in this study was approved by the Ethics Committee of the Naval Medical University, 19YF1459400). A total of 90 chemical constituents were identified from Yin Chen Hao decoction, mainly were flavonoids, terpenoids, tannins, quinones. 5 prototype compounds were identified in the serum, including chrysophanol, deoxyrhapontin-8-O-gallate, mussaenosidic acid, herniarin, emodin. The established UPLC-QTOF/MS method could efficiently and sensitively identify the constituents in vitro and blood-absorbed ingredients of Yin Chen Hao decoction, primarily clarify the material basis of its hepatoprotective effect, and provided a scientific basis for the quality marker selection and the pharmacodynamic material basis research on the decoction.

Objective To investigate the effect of progressive early bed physical activity on blood flow in lower limb of patients on mechanical ventilation in intensive care unit (ICU). Methods Adult patients with mechanical ventilation ≥ 72 hours admitted to ICU of the Affiliated Hospital of Zunyi Medical University from February 22nd to November 30th, 2016 were enrolled. The patients were randomly divided into experimental group and control group by random number table method. Patients in the two groups were given the same basic treatment, including antibiotics, analgesia and sedation, mechanical ventilation, nutritional support, and routine ICU activities such as maintaining functional position of limbs and raising of bed head. On the basis of those, the experimental group was given early bed physical activity with gradual enhancement of grades Ⅰ-Ⅲ according to the nerve, circulation and respiration situations, such as passive/active exercise of the bicycle, straight leg lifting exercise, etc. The exercise intensity was evaluated with target heart rate, and the exercise was performed for 15-30 minutes at a time, twice a day. The control group was given intermittent pneumatic compression (IPC), 30 minutes in each time, twice a day. Mean blood flow and blood volume were measured before and immediately, 5, 10 and 15 minutes after intervention on the 3rd day. Heart rate and blood pressure were measured at 5 minutes before intervention, during 5 minutes, and 5, 10, 15, 30 minutes after intervention on the 3rd day.

Conclusions The effects of progressive early bed physical activity on the mean blood flow velocity and blood volume of lower limbs in ICU patients with mechanical ventilation are better than those of IPC. Although the fluctuation of heart rate and blood pressure is large, it does not cause any harm to the patients.

Objective To investigate personal identification of mixed seminal stain of two individuals, we combined the detection of genotyping autosomal, Y and X STR and sequencing mtDNA hypervariable Ⅰ (HV Ⅰ ) region. Methods We analyzed autosomal, Y and X STR with commercial kit and separating and sequencing HVⅠfragments of mixed seminal stain from two males by SSCP electrophoresis. Results Four genetic markers of the high amount sample can be obtained when mixed ratio is more than 1:10. When the proportion of two samples is close, the suspect could be excluded or, to some extent, identified by comparing with our results. Conclusion The combined detection of four genetic marker systems can, to some degree, solve the personal identification from mixed seminal stain of two individuals.

Arisaema heterophyllum Blume is one of the three medicinal plants known as traditional Chinese medicine Rhizoma Arisaematis (RA). RA has been popularly used to treat patients with convulsions, inflammation, and cancer for a long time. However, the underlying mechanisms for RA effects are still unclear. The present study was designed to determine the cytotoxicity of agglutinin isolated from Arisema heterophyllum Blume (AHA) and explore the possible mechanisms in human non-small-cell lung cancer A549 cells. AHA with purity up to 95% was isolated and purified from Arisaema heterophyllum Blume using hydrophobic interaction chromatography. AHA dose-dependently inhibited the proliferation of A549 cells and induced G phase cell cycle arrest. AHA induced apoptosis by up-regulating pro-apoptotic Bax, decreasing anti-apoptotic Bcl-2, and activating caspase-9 and caspase-3. In A549 cells treated with AHA, the PI3K/Akt pathway was inhibited. Furthermore, AHA induced increase in the levels of ER stress markers such as phosphorylated eukaryotic initiation factor 2α (p-eIF2α), C/EBP-homologous protein (CHOP), inositol-requiring enzyme 1α (IRE1α), and phosphorylated c-Jun NH-terminal kinase (p-JNK). AHA also induced autophagy in A549 cells. Staining of acidic vesicular organelles (AVOs) and increase in the levels of LC3II and ATG7 were observed in AHA-treated cells. These findings suggested that AHA might be one of the active components with anti-cancer effects in Arisaema heterophyllum Blume. In conclusion, cytotoxicity of AHA on cancer cells might be related to its effects on apoptosis and autophagy through inhibition of PI3K/Akt pathway and induction of ER stress.
