Aim To explore the protective effects of LPPC ( procyanidins extracted from the litchi pericarp) on cardiomyocyte apoptosis in septic rats and its mech-anisms. Methods The rats were randomly divided in-to 5 groups, and were given orally the drug for two weeks continuously. The control group ( control) and sepsis model group ( LPS ) were given distilled water once a day. LPPC low, medium and high dose groups were given LPPC 50 , 100 , 200 mg · kg-1 · d-1 re-spectively which were prepared freshly every day. After the treatment, sepsis animal models were established. Except for the control group, other groups were injec-ted LPS (lipopolysacchride, 10mg·kg-1) intraperito-neally to induce acute sepsis model. 4hrs later, rat se-rum was collected, isoenzyme ( CK-MB ) , lactate de-hydrogenase ( LDH ) and activity of aspertate amin-otransferase ( AST/GOT) were detected. Then rat car-diac tissue was obtained and cardiac tissue malondial-dehyde ( MDA ) , total antioxidant capacity ( T-AOC ) and reduced glutathione ( GSH ) content were deter-mined. TUNEL staining was performed to analyze the apoptosis of myocardial cells. Cleaved caspase-3 and TNF alpha protein expressions were analyzed by West-ern blot. Results Compared with the control group ( control) , serum of sepsis model group rats CK-MB, LDH, AST/GOT and cardiac tissue MDA content were significantly increased (P<0. 01). At the same time, the activity of cardiac tissue T-AOC and GSH de-creased obviously ( P<0. 01 ) . The apoptotic myocar-dial cells increased significantly ( P<0. 01 ) , and the expression level of cleaved caspase-3 and TNF alpha decreased obviously ( P <0. 01 ) . LPPC pretreatment significantly decreased the serum CK-MB, LDH, AST/GOT and tissue MDA content, increased tissue T AOC and GSH activity, attenuated apoptosis of rat myocardi-al cells significantly, and decreased expression level of cleaved caspase-3 and TNF alpha. Conclusion LPPC pretreatment can significantly attenuate rat myocardial cell apoptosis induced by sepsis, and the underlying mechanisms may be related to its anti-oxidative effects.

Aim To study the mechanisms of the pro-tective effect of procyanidin B2 ( PCB2 ) on the myocar-dial cell apoptosis induced by lipopolysaccharide ( LPS) . Methods Using the primary culture rat myo-cardial cells, myocardial cell injury model was induced by LPS. PCB2 low, medium and high dose groups, were cultured with 6. 25 , 12. 5 , 25. 0 μmol · L-1 PCB2 respectively in DMEM medium for 24 h continu-ously. Myocardial cell survival rate was determined by MTT colorimetric method. Cardiacmyocyte NOX activi-ty was determined by lucigen chemiluminescence meth-od . Western blot analysis was used to detect myocardi-al NADPH oxidase p47phox expression. TUNEL method was used to detect apoptosis and flow cytometry was used to determine the content of myocardial cells ROS. Results Compared with control group, the cell dam-age induced by LPS group myocardial cell survival rate significantly decreased ( P <0. 01 ) , and myocardial cell NOX activity, p47phox expression, apoptotic cell number and ROS content were significantly increased (P<0. 01). PCB2 low, medium and high dose groups cell survival rates were significantly elevated, myocar-dial cell NOX activity and p47phox expression, apoptotic cell number and the ROS content decreased significant-ly in a dose-dependent manner ( P <0. 01 ) . Conclu-sion PCB2 protects myocardial cell apoptosis induced by LPS via inhibiting the expression of NADPH oxidase activation, p47phox expression and reactive oxygen spe-cies generation.

ObjectiveTo investigate the effect of macrophages (MCs) on the differentiation of mouse induced pluripotent stem cells (iPSCs) into hepatic progenitor cells (HPCs). MethodsA total of 24 C57BL/6N mice were used to obtain MCs by peritoneal irrigation, and the supernatant was collected to obtain the conditioned medium of MCs (MC-CDM). Activin A, bone morphogenetic protein 4, and fibroblast growth factor were used to induce the differentiation of mouse iPSCs into HPCs. The differentiation of HPCs were randomly divided into control group (normal medium) and experimental group (MC group; use of MC-CDM medium on day 5 of induction). Morphology, immunofluorescence assay, and Western blot were used to compare the morphology of HPCs and the expression of related proteins between the control group and the MC group. The t-test was used for comparison of continuous data between two groups. ResultsHPCs derived from iPSCs were established in vitro, and HPCs had the potential to differentiate into hepatocytes. Immunofluorescence assay showed that compared with the D12 control group, the D12 MC group had a significant increase in the protein expression of the HPC-specific protein CK19 (0.901±0.072 vs 0.686±0.097, t=-3.093, P<0.05). Western blot showed that compared with the D12 control group, the D12 MC group had a significant increase in the protein expression of the HPC-related protein CK19 (1.922±0.103 vs 1.448±0.012, t =-7.881, P <005), as well as a significant increase in the protein expression of the autophagy-related protein LC3 (1.392±0.042 vs 1.101±0048, t =-5.978, P<005). ConclusionMCs can promote the differentiation of mouse iPSCs into HPCs, possibly by increasing the autophagy level of HPCs.

Purpose:
Cavernous nerve injury induced erectile dysfunction (ED) is a refractory complication with high incidence in person under radical prostatectomy. Studies have shown that relaxin-2 (RLX-2) plays a vital role of endothelial protection, vasodilation, anti-fibrosis and neuroprotection in a variety of diseases. However, whether penile cavernous erection can benefit from RLX-2 remains unknown. The purpose of the experiment was to explore the effects of RLX-2 on ED in the rat suffering with bilateral cavernous nerve injury (BCNI).
Materials and Methods:
The rats were divided into three groups: Sham group was underwent sham operation, BCNI+RLX group or BCNI group was underwent bilateral cavernous nerve crush and then randomly treated with RLX-2 (0.4 mg/kg/d) or saline by continuous administration using a subcutaneously implanted micro pump for 4 weeks respectively. Then, erectile function was evaluated by electrical stimulation of cavernous nerves. Cavernous nerves and penile tissues and were collected for histological evaluation.
Results:
Erectile function of rats with BCNI was partially improved after RLX-2 treatment. The BCNI group had lower expression of relaxin family peptide receptor (RXFP) 1, p-AKT/AKT, p-eNOS/eNOS ratios than sham operation rats, but RLX-2 could partially reversed these changes. Histologically, the BCNI+RLX group had a significant effect on preservation of neurofilament, neuronal glial antigen 2 of penile tissue and nNOS of cavernous nerves when compared with BCNI group. RLX-2 could inhibited the lever of BCNI induced corporal fibrosis and apoptosis via regulating TGFβ1-Smad2/3-CTGF pathway and the expression of Bax/Bcl-2 ratio, caspase3.
Conclusions
RLX-2 could improve erectile function of BCNI rats by protecting cavernous nerve and endothelial function and suppressing corporal fibrosis and apoptosis via RXFP1 and AKT/eNOS pathway. Our findings may provide a promising treatment for refractory BCNI induced ED.

BACKGROUNDBased on the excellent medical care and management system for Chinese veterans, as well as the detailed medical documentation available, we aim to construct a Chinese Veteran Clinical Research (CVCR) platform on non-communicable diseases (NCDs) and carry out studies of the primary disabling NCDs.
METHODSThe Geriatric Neurology Department of Chinese People's Liberation Army General Hospital and veterans' hospitals serve as the leading and participating units in the platform construction. The fundamental constituents of the platform are veteran communities. Stratified typical cluster sampling is adopted to recruit veteran communities. A cross-sectional study of mental, neurological, and substance use (MNS) disorders are performed in two stages using screening scale such as the Mini-Mental State Examination and Montreal cognitive assessment, followed by systematic neuropsychological assessments to make clinical diagnoses, evaluated disease awareness and care situation.
RESULTSA total of 9 676 among 277 veteran communities from 18 cities are recruited into this platform, yielding a response rate of 83.86%. 8 812 subjects complete the MNS subproject screening and total response rate is 91.70%. The average participant age is (82.01±4.61) years, 69.47% of veterans are 80 years or older. Most participants are male (94.01%), 83.36% of subjects have at least a junior high school degree. The overall health status of veterans is good and stable. The most common NCD are cardiovascular disorders (86.44%), urinary and genital diseases (73.14%), eye and ear problems (66.25%), endocrine (56.56%) and neuro-psychiatric disturbances (50.78%).
CONCLUSIONWe first construct a veterans' comprehensive clinical research platform for the study of NCDs that is primarily composed of highly educated Chinese males of advanced age and utilize this platform to complete a cross-sectional national investigation of MNS disorders among veterans. The good and stable health condition of the veterans could facilitate the long-term follow-up studies of NCDs and provide prospective data to the prevention and management of NCDs.
