ABSTRACT

The aim of this study was to investigate the role of selenoprotein M (SelM) in endoplasmic reticulum stress and apoptosis in nickel-exposed mouse hearts and to explore the detoxifying effects of melatonin. At 21 d after intraperitoneal injection of nickel chloride (NiCl2) and/or melatonin into male wild-type (WT) and SelM knockout (KO) C57BL/6J mice, NiCl2 was found to induce changes in the microstructure and ultrastructure of the hearts of both WT and SelM KO mice, which were caused by oxidative stress, endoplasmic reticulum stress, and apoptosis, as evidenced by decreases in malondialdehyde (MDA) content and total antioxidant capacity (T-AOC) activity. Changes in the messenger RNA (mRNA) and protein expression of genes related to endoplasmic reticulum stress (activating transcription factor 4 (ATF4), inositol-requiring protein 1 (IRE1), c-Jun N-terminal kinase (JNK), and C/EBP homologous protein (CHOP)) and apoptosis (B-cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), Caspase-3, Caspase-9, and Caspase-12) were also observed. Notably, the observed damage was worse in SelM KO mice. Furthermore, melatonin alleviated the heart injury caused by NiCl2 in WT mice but could not exert a good protective effect in the heart of SelM KO mice. Overall, the findings suggested that the antioxidant capacity of SelM, as well as its modulation of endoplasmic reticulum stress and apoptosis, plays important roles in nickel-induced heart injury.

ABSTRACT

5-Aminolevulinic acid (5-ALA) has been approved for clinical photodynamic therapy (PDT) due to its negligible photosensitive toxicity. However, the curative effect of 5-ALA is restricted by intracellular biotransformation inactivation of 5-ALA and potential DNA repair of tumor cells. Inspired by the crucial function of iron ions in 5-ALA transformation and DNA repair, a liposomal nanomedicine (MFLs@5-ALA/DFO) with intracellular iron ion regulation property was developed for boosting the PDT of 5-ALA, which was prepared by co-encapsulating 5-ALA and DFO (deferoxamine, a special iron chelator) into the membrane fusion liposomes (MFLs). MFLs@5-ALA/DFO showed an improved pharmaceutical behavior and rapidly fused with tumor cell membrane for 5-ALA and DFO co-delivery. MFLs@5-ALA/DFO could efficiently reduce iron ion, thus blocking the biotransformation of photosensitive protoporphyrin IX (PpIX) to heme, realizing significant accumulation of photosensitivity. Meanwhile, the activity of DNA repair enzyme was also inhibited with the reduction of iron ion, resulting in the aggravated DNA damage in tumor cells. Our findings showed MFLs@5-ALA/DFO had potential to be applied for enhanced PDT of 5-ALA.

ABSTRACT

Objective:To explore the eye movement characteristics of social cognitive processing in schizophrenia patients across different stages and its association with clinical symptoms.Methods:Fifteen patients with first-episode schizophrenia, forty-six patients with chronic inpatient schizophrenia, thirty-six patients with psychiatric clinical high-risk syndrome, and twenty-six healthy controls were recorded using eye tracking technology when viewing social interaction pictures. Covariance analysis and partial correlation analysis were conducted by SPSS17.0.Results:When watching the pictures of person communication, there were statistically significant differences in the average fixation duration of the four groups of subjects ((294.6±36.7)ms in control group, (280.0±54.0)ms in clinical high-risk group, (268.5±34.9)ms in first-episode group, and (315.7±75.7) ms in chronic group, respectively, F=3.18, P=0.027). When viewing the pictures of no person landscape, the average saccade amplitude of the four groups of subjects was significantly different (5.3±1.1) ° in control group, (4.7±1.1) ° in clinical high-risk group, (5.2±1.0) ° in first-episode group, and (4.4±1.2) ° in chronic group, respectively, F=3.37, P=0.021). The average fixation duration of chronic patients when observing person communication pictures was positively correlated with the total score of PANSS (partial correlation coefficient=0.313, P=0.039). The average fixation duration of chronic patients when observing the other two types of pictures were also positively correlated with the total score of PANSS (partial correlation coefficient=0.320, P=0.034, no person communication pictures; partial correlation coefficient=0.372, P=0.013, no person landscape pictures) . The average fixation duration of chronic patients when observing pictures of no person landscape was positively correlated with the PANSS positive symptom score (partial correlation coefficient=0.321, P=0.034). The average fixation duration of chronic patients when observing any type of picture was positively correlated with the PANSS general symptom score (person communication pictures: partial correlation coefficient=0.385, P=0.010; no person communication pictures: partial correlation coefficient=0.409, P=0.006; no person landscape pictures: partial correlation coefficient=0.465, P=0.001). In the first-episode patient, the average saccade amplitude when observing no person communication pictures was positively correlated with the PANSS positive symptom score (partial correlation coefficient=0.555, P=0.049). In the clinical high-risk group, the average saccade amplitude when observing person communication pictures was negatively correlated with the SOPS positive symptom score (partial correlation coefficient=-0.373, P=0.030). Conclusion:There are statistically significant differences of eye movement characteristics of social cognitive processing in patients with schizophrenia across different clinical stages.The average saccade amplitude is more sensitive than the average fixation duration in predicting the severity of symptoms in clinical high-risk patients.

ABSTRACT

Objective:To investigate the potentially inappropriate medication(PIM)among elderly patients with chronic diseases in Shanghai communities and related influence factors.Method:Six community Health service Centers were choosen using stratified sampling. Total 968 elderly patients with chronic diseases who visited to the outpatient clinic of Shanghai Community Health Service Centers from July to August 2018 were included in the study. The PIM was investigated according to the 2015 Beers criteria. The χ 2 test and multivariate logistic regression model were used to analyze factors related to the PIM. Results:The survey showed that 317 elderly patients had PIM with 412 person-doses. In 134 person-doses, the PIM was unrelated to the disease; in 18 person-doses, PIM was caused by interaction of drug with disease/symptoms; in 259 person-doses PIM was related to the drugs that should be cautiously used for elderly; only in 1 person-dose the PIM was caused by the interaction between drugs. The drugs with the highest proportion of PIM were diuretics, benzodiazepines and aspirin. There were significant differences in age, kinds of diseases, kinds of drugs and times of visiting community health service centers between elderly patients with PIM and those without PIM (χ 2=42.28, 35.51, 46.47, 38.46; all P<0.05). The main PIM-related factors were age, kinds of diseases, kinds of drugs and times of visiting community health service centers. Conclusion:The study shows that the prevalence of PIM among elderly chronic diseases patients in Shanghai communities is relatively high, which is associated with the age, kinds of diseases, kinds of drugs and times of visiting community health service centers.

The determination was carried out on Agilent ZORBAX Eclipse Plus C18 column with mobile phase consisted of acetonitrile-0.2% formic acid solution (gradient elution) at the flow rate of 1.0 mL/min. The detection wavelength was set at 270 nm, and column temperature was 30 ℃. The sample size was 10 μL. Using baicalin as reference, HPLC fingerprints of 10 batches of samples were determined. The similarity of 10 batches of samples was evaluated by TCM Chromatographic Fingerprint Similarity Evaluation System (2012 edition) to confirm common peak. Cluster analysis and principal component analysis were performed by using SPSS 22.0 software. RESULTS: There were 21 common peaks in HPLC chromatograms of 10 batches of samples, the similarity of which was all over 0.95, which indicated that in 10 batches of samples, the chemical composition was consistent, but the contents of these components were different. When euclidean distance was equal to 25,10 batches of sample were divided into two categories; S3 was included in the first category, and others were included in the second category. When euclidean distance was equal to 5, the second category could be divided into three sub-categories, one sub-category was S2, S4, S6 and S10; one sub-category was S5, S9; one sub-category was S1, S7, S8. Through the principal component analysis, the cumulative contribution rate of three main component factors was 90.642%, and comprehensive score of S3 was the highest with the best quality. CONCLUSIONS: Established HPLC fingerprint, the results of cluster analysis and principal component analysis can provide reference for quality evaluation of Nüjin pills.

ABSTRACT

Objective To investigate the effect of quadratus lumborum block on postoperative analgesia and T lympho-cyte subsets in patients receiving transabdominal radical resection of rectal cancer, so as to provide clinical references. Methods From May 2016 to November 2017, 30 patients receiving selective radical resection of rectal cancer in our hospital were selected. The random number table was used to divide the patients into quadratus lumborum block group(experimental group) and incision partial infiltration block group (control group), with 15 patients in each group. After induction of general anesthesia, the experimental group underwent ultrasound-guided bilateral anterior lateral quadratus lumborum block. Each side was injected with 0. 375% ropivacaine of 20 mL. The control group was induced by general anesthesia and 0. 375% ropivacaine of 40 mL was injected for local infiltration block. The surgery time, volume of blood loss, total infusion volume of propofol, effective analgesia time, the amount of sufentanil infusion every 12 hours after surgery and resting VAS scores at postoperative different time points (2, 6, 12, 24, 36, 48 hours postoperatively) were observed and recorded. Venous blood (1 mL) was drawn 30 minutes before anesthesia(TO), 2 hours after surgery(T1), 1 day after surgery(T2) and 3 days after surgery(T3). T lymphocyte subsets were detected by flow cytometry(CD3+, CD4+, CD8+, CD4+/CD8+). Results Compared with the control group, the dosage of propofol in the experimental group was significantly less than that in the control group (P<0. 05); the effective analgesia time in the experimental group was significantly longer than that in the control group (P<0. 0l); the amount of sufentanil in the experimental group was significantly less than that in the control group at 0-12 h and 12-24 h after surgery (P<0. 05); the resting VAS scores in the experimental group at 6 h and 12 h after the surgery were significantly lower than those in the control group (P<0. 05); the levels of CD3+, CD4+, CD4+/CD8+ in the experimental group were significantly higher than those in control group at T2 (P<0. 05). Compared with TO, CD3+, CD4+, CD4+/CD8+ at T1 and T2 in the two groups were significantly lower than those at TO(P<0. 05); at T2, CD8+ in the control group was significantly lower than that at TO(P<0. 05). Conclusion Bilateral quadratus lumborum block can significantly improve postoperative analgesia effect in patients receiving radical resection of rectal cancer and reduce the inhibition of T lymphocytes by surgical stress.

ABSTRACT

Objective To investigate the eye-movement features of smooth pursuit in subjects at clinical high risk for psychosis.Methods sixty subjects at clinical high risk for psychosis and sixty healthy controls were recruited.The smooth pursuit tasks were assessed in both horizontal (0.4 Hz) and Lissajous (0.2 or 0.4 Hz) condition.The Wechsler Memory Scale-third edition and spatial span subtest were used to assess working memory.The difference of the smooth pursuit performance between the two groups and the relationship between smooth pursuit and working memory were analyzed.Results Subjects at clinical high risk for psychosis showed significantly lower Horizontal components for pursuit gain [Lissajous 0.2 Hz task (0.82±0.12) vs.(0.89±0.09),Lissajous 0.4 Hz task (0.78±0.13) vs.(0.84±0.14)],lower vertical components for pursuit gain [Lissajous 0.2 Hz task (0.80±0.14) vs.(0.86±0.12),Lissajous 0.4 Hz task (0.71±0.15)vs.(0.77±0.16)] and higher mean positional error [Lissajous 0.2 Hz task (37.00±19.10) vs.(30.45± 16.18),Lissajous 0.4 Hz task (44.18±19.70) vs.(37.61±16.26)] compared to healthy controls (P<0.05).There was a significant correlation between pursuit gain and performance on Spatial Span (Horizontal components:r=0.361,P=0.005;vertical components:r=0.327,P=0.01 1) in the Subjects at clinical high risk for psychosis.Conclusions Subjects at clinical high risk for psychosis showed deficits in smooth pursuit,and the deficits were related to the working memory.

ABSTRACT

OBJECTIVE:To develop a method for simultaneous determination of chlorogenic acid,baicalin,aloe emodin,rhe-in,emodin,chrysophanol and physcione in Kangjun xiaoyan tablets. METHODS:RP-HPLC method was adopted. The determina-tion was performed on Agilent Extend C18 with mobile phase consisted of acetonitrile-0.5% phosohoric acid solution(gradient elu-tion)at the flow rate of 1.0 mL/min. The detection wavelengths were set at 327 nm(chlorogenic acid),280 nm(baicalin)and 450 nm(aloe emodin,rhein,emodin,chrysophanol,physcione). The column temperature was 30℃,and sample size was 10μL. RE-SULTS:The linear ranges of chlorogenic acid,baicalin,aloe emodin,rhein,emodin,chrysophanol and physcione were 0.2094-4.1880μg(r=0.9999),0.3720-7.4400 μg(r=0.9999),0.0063-0.1262 μg(r=0.9999),0.0116-0.2322 μg(r=0.9999),0.0053-0.1060 μg(r=0.9998),0.0128-0.2564 μg(r=0.9999),0.0165-0.3303 μg(r=0.9998),respectively. The limits of quantita-tion were 2.01,1.93,0.76,1.25,1.24,0.53 and 1.53 ng;the limits of detection were 0.98,0.65,0.25,0.42,0.41,0.18 and 0.52 ng,respectively. The recoveries were 98.41%-100.40%(RSD=0.76%,n=9),96.17%-100.10%(RSD=1.58%,n=9), 96.11%-100.10%(RSD=1.33%,n=9),96.29%-100.80%(RSD=1.85%,n=9),96.88%-100.10%(RSD=1.22%,n=9), 97.81%-101.90%(RSD=1.64%,n=9),96.46%-101.30%(RSD=1.85%,n=9),respectively.
