Effects of Dengzhan Shengmai Capsule combined with butylphthalide soft capsule on oxidative stress indexes and serum Hcy and CRP levels in patients with vascular dementia.
This experiment was aimed to investigate the effect of Dengzhan Shengmai capsule combined with butylphthalide soft capsule on oxidative stress indexes and serum homocysteine (Hcy) and C-reactive protein (CRP) levels in patients with vascular dementia (VD). From July 2017 to July 2019, 123 patients with VD in our hospital were selected as the research object, and each patient was assigned a random number according to the order of treatment. Among them, No. 1 to 41 were the control group A, No. 42 to 82 were the control group B, and No. 83 to 123 were the research group. ⋯ In oxidative stress experiment, after the course of treatment in the study group, the serum LPO and MDA levels were lower than those in the control groups A and B, and the SOD levels were higher than those in the control groups A and B (p<0.05). Endoplasmic reticulum stress response results showed that after the course of treatment in the study group, the serum Hcy and CRP levels were lower than those in the control groups A and B (p<0.05). In adverse reactions section, there was no significant difference in the incidence of adverse reactions among the three groups (p>0.05). Dengzhan Shengmai Capsule combined with butylphthalide soft capsule is the first treatment for VD, with definite curative effect, which can effectively reduce the damage of vascular endothelial function and inhibit oxidative stress response, antagonize the endoplasmic reticulum stress response, thereby further alleviating dementia symptoms and improving cognitive function.

Molecular detection of type III secretory toxins in Pseudomonas aeruginosa isolates.
Pseudomonas aeruginosa has been known as a common unscrupulous pathogen that reasons cause nosocomial infections in patients with immunocompromise. Infection with multi-drug resistant Pseudomonas aeruginosa infection in many patients is a public health problem. The bacterium causes urinary tract infections, respiratory tract infections, skin inflammation and inflammation, soft tissue infections, bacteremia, bone and joint infections, gastrointestinal infections and various systemic infections, especially in patients with severe burns, cancer and AIDS, whose immune systems are suppressed. ⋯ The occurrence of the ExoS and ExoU genes was 97.7% and 86.6% among clinical isolates while none of the raw milk isolates harbored the ExoU gene and 60% of them carried the ExoS gene. The results found 20 (40%) of isolates were multidrug resistance and the most effective antibiotics against clinical isolates were Ciprofloxacin and Meropenem. The aim of this study was to prevalence the exotoxin genes encoded type III secretion system and pattern of antimicrobial susceptibility of P. aeruginosa isolated from clinical and raw milk specimens.

Cancer-associated fibroblasts induce immunotherapy resistance in hepatocellular carcinoma animal model.
Hepatocellular carcinoma is known to be a common predominant cancer in adults, especially in eastern countries. Immune response and cancer-associated fibroblasts (CAFs) have significant influences on tumor development. However, the interaction between CAFs and immunotherapy is unclear in hepatocellular carcinoma. ⋯ In the treatment model, tumors with a higher amount of CAFs had been insensitive to therapy with anti-PD-1. CAFs are potent inducers of immunosuppression in hepatocellular carcinoma. Depleting CAFs rescued the antitumor immunity in the hepatocellular model and could be a novel treatment to combine with the existing immunotherapy.

Meta AnalysisThe role of lactate deshydrogenase levels on non-small cell lung cancer prognosis: a meta-analysis.
The role of serum lactate dehydrogenase (LDH) on the clinical outcomes of non-small cell lung cancer (NSCLC) patients with epidermal growth factor receptor (EGFR) tyrosine-kinase inhibitors (TKIs) treatment remained to be elucidated. Therefore, we did this meta-analysis. We searched databases including PubMed, EMBASE, and Cochrane Library till to June, 2017. ⋯ As for OS, patients with high levels of LDH showed significantly shorter OS (HR=2.44; 95%CI, 1.84-3.23). In the subgroup by race, significant associations were found in Asian group (HR=2.62; 95%CI, 1.61-4.26) and Caucasian population (HR=2.36; 95%CI, 1.66-3.34). In conclusion, this meta-analysis suggested that elevated LDH level was associated with the poor PFS and OS of NSCLC patients receiving EGFR-TKIs treatment.

Comparative StudyComparison of the cytotoxic, genotoxic and apoptotic effects of Sugammadex and Neostigmine on human embryonic renal cell (HEK-293).
Acetylcholinesterase inhibitors, including Neostigmine, have been used to reverse neuromuscular blockage for many years. Sugammadex reverses this blockage using its gamma cyclodextrin ring, a mechanism that differs from that of cholinesterases and so circumvents the side effects of Neostigmine. Although the superiority of Sugammadex to Neostigmine has been outlined in several clinical studies, to our knowledge, there is not any research into cell culture that compares the cytotoxic, genotoxic and apoptotic effects of the two drugs. ⋯ The results demonstrate that Neostigmine at 50, 100, 250, and 500 µg/mL is more cytotoxic than equivalent dosages of Sugammadex. Neostigmine at 500 and 1000 µg/mL was found to be more genotoxic, and Neostigmine at 500 µg/mL had a statistically higher risk of causing apoptosis and necrosis than Sugammadex (p<0.05). Neostigmine administered in-vitro in the same doses as Sugammadex had greater cytotoxic, genotoxic and apoptotic effects on HEK-293 cells.
