The effect of astaxanthin on N(Ω)-nitro-L-arginine methyl ester (L-NAME) induced preeclampsia disease rats was investigated. Thirty pregnant Spraque-Dawley rats were randomly divided into three groups (n = 10): blank group, L-NAME group and astaxanthin group. From day 5 to 20, astaxanthin group rats were treated with astaxanthin (25 mg x kg(-1) x d(-1) x bw(-1)) from pregnancy (day 5). To establish the preeclamptic rat model, L-NAME group and astaxanthin group rats were injected with L-NAME (125 mg x kg(-1) x d(-1) x bw(-1)) from days 10-20 of pregnancy. The blood pressure and urine protein were recorded. Serum of each group was collected and malondialdehyde (MDA), superoxide dismutase (SOD) and nitric oxide synthase (NOS) activities were analyzed. Pathological changes were observed with HE stain. The expression of NF-κB (nuclear factor kappa B), ROCK II (Rho-associated protein kinase II), HO-1 (heme oxygenase-1) and Caspase 3 were analyzed with immunohistochemistry. L-NAME induced typical preeclampsia symptoms, such as the increased blood pressure, urinary protein, the content of MDA, etc. Astaxanthin significantly reduced the blood pressure (P < 0.01), the content of MDA (P < 0.05), and increased the activity of SOD (P < 0.05) of preeclampsia rats. The urinary protein, NO, and NOS were also decreased. HE stain revealed that after treated with astaxanthin, the thickness of basilal membrane was improved and the content of trophoblast cells and spiral arteries was reduced. Immunohistochemistry results revealed that the expressions of NF-κB, ROCK II and Caspase 3 in placenta tissue were effectively decreased, and HO-1 was increased. Results indicated that astaxanthin can improve the preeclampsia symptoms by effectively reducing the oxidative stress and inflammatory damages of preeclampsia. It revealed that astaxanthin may be benefit for prevention and treatment of preeclampsia disease.

Objective To investigate the effect of extract ofTangshen-HuazhuoRecipe(TSHZR) on the serum concentrations of transforming growth factorβ1(TGF-β1) and platelet derived growth factor(PDGF) in patients withⅣ stage of diabetic nephropathy(DN).Methods From June 2012 to December 2012, 98 patients ofⅣstage DN in our hospital outpatient were enrolled and randomly divided into treatment group(n=48) and control group(n=50) using random number table. All patients received conventional therapies of controlling blood sugar, lipid, blood pressure and anticoagulant therapy. On such basis, the control group was treated by irbesartan, 150 mg/d, and the treated group treated by TSHZR combined with irbesartan,150 mg/d, for 6 months. Serum TGF-β1 and PDGF were determined with ELISA before and after treatment,and urinary albumin excretion rate,HbA1c,serum creatinine,blood urea nitrogen and lipid profiles were examined as well. ResultsIn the treated group, the TGF-β1 was(172.5±31.3), (123.6±21.2)pg/ml, the PDGF was(860.9± 131.2), (500.6±130.2)pg/ml before the treatment and after the treatment, respectively. The TGF-β1 and PDGF after the treatment were significantly decreased than those before the treatment(P<0.01). After the treatment, TGF-β1 and PDGF in the treated group were statistically significant compared to the control group[TGF-β1 is(157.4±39.6)pg/ml, PDGF is(765.7±161.8)]pg/ml,P<0.01). After the treatment, the treatment group was superior to the control group in TG(1.72±0.25)mmol/L,(2.09±0.27)mmol/L,(P<0.01), TC(4.56± 0.64)mmol/L,(6.11±0.93)mmol/L, (P<0.01), HDL-C(1.56±0.50)mmol/L,(1.36±0.44)mmol/L, (P<0.01), LDL-C(2.46±1.08)mmol/L(3.32±0.87)mmol/L,(P<0.05)and UAER(100.73±204.24)μg/min, (226.24±396.38)μg/min, (P<0.01).Conclusion TSHZR can inhibit the progressive of IV stage of diabetic nephropathy by suppressing TGF-β1 and PDGF expression level.

Objective:To investigate the relationship between serum fibrous gel protein-3 (ficolin-3) and serum alanine (ALA) levels and gestational diabetes (GDM) .Methods:A total of 98 pregnant women with GDM admitted to our hospital from Jan. 2020 to Aug. 2020 were selected as the observation group, and 98 healthy pregnant women undergoing physical examination during the same period were taken as the control group. The level of serum ficolin-3 was measured by enzyme-linked immunosorbent assay (ELISA) , and the level of serum ALA was measured by high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) . The two groups were compared in terms of serum ficolin-3, ALA levels and biochemical indicators (hemoglobin (HbA1c) , total cholesterol (TC) , high-density lipoprotein cholesterol (HDL-C) , low-density lipoprotein cholesterol (LDL-C) , serum total protein (TP) , serum urea (SU) levels) , and pregnancy outcomes. Pearson method was used to analyze the correlation between serum ficolin-3 and ALA levels and various biochemical indexes. Univariate analysis and binary logistic regression analysis were used to investigate the risk factors of GDM.Results:Serum ficolin-3, HbA1c, and SU levels in the observation group were all higher than that in the control group. Serum ALA level was lower than that in the control group, and the difference was statistically significant ( P<0.05) . TC, HDL-C, LDL-C, TPT showed no significant difference between the two groups ( P>0.05) . In the observation group, serum ficolin-3 was positively correlated with HbA1c and Su, and serum ALA was negatively correlated with HbA1c and SU ( P < 0.05) . The incidence of adverse outcomes including gestational neonatal asphyxia, neonatal jaundice, giant size, and amniotic fluid contamination in the observation group (26.53%) was higher than that in the control group (12.24%) , The difference was statistical significant ( P<0.05) . The univariate analysis showed that GDM was associated with age, weight gain during pregnancy, serum ficolin-3, ALA, HbA1c, SU, family history of diabetes ( P<0.05) ; Binary logistics regression analysis found that age ≥28 years, weight gain≥ 14 kg, serum ficolin-3≥24ng/ml, HbA1c 6.0%, and a family history of diabetes were risk factors for GDM, while serum ALA≥1.9 μg/ml was a protective factor of GDM, ( P<0.05) . Conclusion:The increase of serum ficolin-3 and the decrease of ALA level in pregnant women are risk factors of GDM, and have an adverse impact on the final delivery outcome

Objective:
Attentional biases toward emotional scenes may represent vulnerability and maintenance factors in depression. Antidepressant therapy may improve cognitive function and reduce depression, and is considered as the mechanism of action of antidepressants. Therefore, we conducted an eye-tracking test to examine whether selective serotonin re-uptake inhibitor (SSRI) antidepressants can reduce negative attentional biases and elicit clinical responses in depression.
Methods:
Twenty first-episode depressive patients freely viewed three types of pictures that depicted different emotional scenes (i.e., positive-control, neutral-control, and negative-control) for 4,000 ms while their eye movements were monitored. The attentional bias to different emotional scenes was assessed before and after eight weeks of SSRI treatment using the eye-tracking method. The control group included a group of healthy individuals.
Results:
The results revealed that first-episode depressive patients oriented their gaze more frequently to negative images and less to happy images, compared to controls. Importantly, the attentional bias in depressive patients was regulated after eight weeks of SSRI treatment. Patients showed an increased tendency to fixate on positive images and a decreased tendency to focus on negative images.
Conclusion
This suggests that SSRI antidepressants decrease vulnerability to negative images, while having an effect on attention in respect to positive images.

By organizing and studying on the original works of LI Wenrong, this paper aimed to explore his theories and methods for treating liver diseases. LI Wenrong believes that the liver is easily prone to physiological disturbances, difficult to pacify, and can be compared to a “chariot” that moves horizontally and vertically, acting as a “general” for both civil and military affairs. Pathologically, liver diseases tend to spread to other organs, resulting in ever-changing pathological changes, often affecting emotional health. In terms of therapeutic methods, LI Wenrong proposes ten methods including draining fire to calm the liver, nourishing water to moisten wood, clearing metal to calm the liver, calming gallbladder and harmonizing liver, subduing yang with shell-drug, treating liver diseases by supplementing spleen, soothing the liver with sweetness, astringing the liver with sourness, relieving the liver with spiciness, and draining the liver with excess-fire. These methods have great guidance and reference value for contemporary clinical practice in traditional Chinese medicine.

Managing the dysregulated host response to infection remains a major challenge in sepsis care. Chinese treatment guideline recommends adding XueBiJing, a five-herb medicine, to antibiotic-based sepsis care. Although adding XueBiJing further reduced 28-day mortality modulating the host response, pharmacokinetic herb-drug interaction is a widely recognized issue that needs to be studied. Building on our earlier systematic chemical and human pharmacokinetic investigations of XueBiJing, we evaluated the degree of pharmacokinetic compatibility for XueBiJing/antibiotic combination based on mechanistic evidence of interaction risk. Considering both XueBiJing‒antibiotic and antibiotic‒XueBiJing interaction potential, we integrated informatics-based approach with experimental approach and developed a compound pair-based method for data processing. To reflect clinical reality, we selected for study XueBiJing compounds bioavailable for drug interactions and 45 antibiotics commonly used in sepsis care in China. Based on the data of interacting with drug metabolizing enzymes and transporters, no XueBiJing compound could pair, as perpetrator, with the antibiotics. Although some antibiotics could, due to their inhibition of uridine 5'-diphosphoglucuronosyltransferase 2B15, organic anion transporters 1/2 and/or organic anion-transporting polypeptide 1B3, pair with senkyunolide I, tanshinol and salvianolic acid B, the potential interactions (resulting in increased exposure) are likely desirable due to these XueBiJing compounds' low baseline exposure levels. Inhibition of aldehyde dehydrogenase by 7 antibiotics probably results in undesirable reduction of exposure to protocatechuic acid from XueBiJing. Collectively, XueBiJing/antibiotic combination exhibited a high degree of pharmacokinetic compatibility at clinically relevant doses. The methodology developed can be applied to investigate other drug combinations.
