Causal associations between serum amino acid levels and osteoarthritis: a Mendelian randomization study.

OBJECTIVE: The association between serum amino acid (AA) levels and osteoarthritis (OA) risk remains unclear. METHOD: We performed a two-sample Mendelian randomization (MR) analysis to analyze the causal effects of serum AA levels on the OA risk by using summary-level genome-wide association study (GWAS) data. Inverse variance weighted (IVW) and Wald ratio were used as the main analysis. We also applied MR-Egger, Weighted median and Robust Adjusted Profile Score (MR.RAPS) methods. Heterogeneity and horizontally pleiotropic outliers were checked. The causal effects of AAs on early-onset all OA were explored. We also performed multivariable MR (MVMR) and conducted the bidirectional MR. RESULTS: The results suggested that genetically predicted alanine (Ala), tyrosine (Tyr) and isoleucine (Ile) levels were significantly associated with OA risk [e.g., association between Ala and hip/knee OA risk: OR = 0.82, 95% confidence interval (CI) = 0.75-0.90, P = 1.54E-05]. The study yielded little evidence of associations between genetically predicted AA levels with early-onset all OA risk. When adjusting the body mass index (BMI) in the MVMR model, suggestive causal effects of Ala and Tyr were also identified, while the effects of Ile substantially attenuated with OA risk. No significant associations between OA and AA levels were observed after testing for bidirectionality. CONCLUSIONS: Some AAs, such as Ala, Tyr and Ile likely affects the OA risk especially at hip or knee joints. The findings highlight the important role that serum AAs might play in the development of OA and provided new treatment approaches to OA.

Objective: To evaluate the effect of "Smoking cessation: Doctor first" program on smoking medical staff. Methods: From December 2016 to September 2019, 1 747 smoking medical staff from 54 units of China Tobacco Cessation Alliance were enrolled into"Smoking cessation: Doctor first"program. Demographic characteristics, smoking characteristics, degree of tobacco dependence, willingness to quit smoking and other related factors were collected during the baseline survey. Multivariate logistic regression model was used to analyze the related factors of willingness to quit. The subjects were given intensive smoking cessation intervention from October 2017 to September 2019, including education on the hazards of smoking, methods of smoking cessation and giving smoking cessation drugs. After intervention, the subjects were investigated about their smoking cessation progress and the effect of the project was evaluated. Results: The subjects were (41±11) years old, 91.9% (1 609/1 747) were male and 62.2% (1 086/1 747) were daily smokers. The main reasons for smoking included the influence of friends [697 (39.9%)], the need for social entertainment [629 (36.0%)], the relief of mental stress [589 (33.7%)] and the refreshment [459 (26.3%)]. At baseline, 52.9% (885/1 672) and 43.2% (755/1 747) smokers had intention to quit smoking and had planned to quit within one year, respectively. Multivariate logistic regression model analysis showed that: low education level [OR (95%CI) of high school and junior high school and below were 2.42 (1.61, 3.63) and 1.57 (1.18, 2.11)], daily smoking [OR (95%CI): 1.38 (1.06, 1.78)], thinking quitting smoking is not important [OR (95%CI): 4.15 (3.33, 5.18)] and having no quitting experience [OR (95%CI): 3.21 (2.53, 4.05)] were associated with no intention to quit smoking. After intensive smoking cessation intervention, 81.0% (1 415/1 747) smokers started to quit and 36.6% (518/1 415) quit smoking with drugs, both higher than the baseline level (all P values<0.001). By the end of the program, 60.2% (852/1 415) of the medical staff had quit smoking successfully. Conclusion: "Smoking cessation: Doctor first"program can improve the willingness to quit and the proportion of using smoking cessation drugs of medical staff.

[Analysis of sleep quality of a prison police].

Objective: To investigate the sleep quality of prison policemen and explore its influencing factors, so as to provide reference for improving the sleep quality of prison policemen. Methods: In August 2013, 177 policemen in a prison were selected by cluster sampling. The sleep quality of 177 prison policemen was investigated by Pittsburgh Sleep Quality Index Scale and General Situation Questionnaire, and the influencing factors were analyzed. Results: The PSQI scores of 177 prison policemen were (7.47+3.80). There were significant differences between the PSQI scores of prison policemen and the normal adult norm (P<0.05). According to the standard of poor sleep quality, 84 prison policemen (47.46%) had poor sleep quality, and the prison policemen scored higher on daytime dysfunction, subjective sleep quality, sleeping time and sleeping time components. Single factor t test and single factor variance analysis showed that there were significant differences in sleep quality among prison policemen in gender, age, educational level and job classification (P <0.05). The results of multiple stepwise regression analysis showed that gender, age and job classification entered the regression equation with PSQI total score as dependent variable (ß=0.167, 0.270, 0.222) . Conclusion: The sleep quality of prison policemen is worse than that of normal adults, and is affected by gender, age, job classification and other factors, which should be paid attention to by prison administrators.

[Surgical technique and outcomes of uteri retrieval from brain-dead multi-organ donors: a preclinical research of human uterine transplantation].

Objective: To evaluate the surgical technique and outcomes of uteri retrieval from brain-dead multi-organ donors.This study is a preclinical research of human living uterine transplantation. Methods: From May, 2015 to May, 2017, four uteri retrieval procedures, characterized with radical hysterectomy and uterine vascular pedicles dissection, were performed in multi-organ brain-dead donors.The uterus was the third authorized organ after the kidney and liver retrieval procedures in the first two cases.The uterine pedicles included the uterus, ovaries, fallopian tubes, the upper one-third of the vagina and internal iliac vessels or external iliac vessels.The perfusion of the uterus was conducted after the retrieval for evaluating the availability, followed by histopathological examination of the uterine issues per 30 minutes. Results: Since the uterine vein was quite difficult to identify and dissect in the first two case, which result in the rupture of triple uterine veins.Therefore, the uterine venous vessels including uterine vein connected with internal iliac vein and internal iliac arteries were selected as vascular grafts and dissected successfully in the last two cases, which could be perfused with the mixture of 4 ℃ heparinized physiological saline through each artery because of shortening the surgical time and arranging the uterine procurement as the first authorized organ procedure.Mean (SD) operative time was 152.5±39.0 min (115-215 min, n=4). Conclusion: Our preliminary experience indicated that the uterus could be retrieved from the brain-dead multi-organ donors and transplanted to the recipient.The attempt of skeletonizing the uterine veins should be replaced by dissection of internal iliac vein.

Objective: To investigate the sleep quality of the employed nurses in three grade A tertiary military hospitals in Beijing, China and its influential factors and to provide a reference for improving the sleep quality of employed nurses. Methods: From January 2014 to January 2017, a questionnaire survey was carried out to investigate the sleep quality of 253 employed nurses in three grade A tertiary military hospitals in Beijing, China using the Pittsburgh Sleep Quality Index (PSQI) and a general status questionnaire. The results were compared with the adult norms to analyze the influential factors for sleep quality of the employed nurses. Results: The global PSQI score of the 253 employed nurses was 7.76 ± 3.53. Their global PSQI score and PSQI component scores were significantly higher than the adults norms (P<0.05) . And 54.94% of the employed nurses had poor sleep quality; they had high scores of daytime dysfunction (1.39±0.83) , sleep latency (1.67±0.94) , sleep quality (1.33±0.88) , and sleep time (1.23±0.78) . The one-way analysis of variance showed that the sleep quality of the employed nurses was associated with nursing age, educational background, professional title, whether to have children, frequency of night shifts, and department (P<0.05) . The multivariate logistic regression analysis showed that the risk factors for sleep quality of the employed nurses were technical secondary school education (OR=4.292) and emergency department and intensive care unit (OR=2.582) ; the protective factors for sleep quality of the employed nurses were outpatient department and assistant department (OR=0.312) , no children (OR=0.318) , and no night shift (OR=0.332) . Conclusion: The employed nurses in military hospitals have poorer sleep quality than the normal adults. The influential factors for sleep quality of employed nurses are educational background, department, whether to have children, and frequency of night shifts.

Observation of Double Impurity Critical Gradients for Electromagnetic Turbulence Excitation in Tokamak Plasmas.

The impact of impurity ions on a pedestal has been investigated in the HL-2A Tokamak, at the Southwestern Institute of Physics, Chengdu, China. Experimental results have clearly shown that during the H-mode phase, an electromagnetic turbulence was excited in the edge plasma region, where the impurity ions exhibited a peaked profile. It has been found that double impurity critical gradients are responsible for triggering the turbulence. Strong stiffness of the impurity profile has been observed during cyclic transitions between the I-phase and H-mode regime. The results suggest that the underlying physics of the self-regulated edge impurity profile offers the possibility for an active control of the pedestal dynamics via pedestal turbulence.

Exploration of gastric carcinogenesis from the relationship between bile acids and intestinal metaplasia and intragastric microorganisms (H. pylori and non-H. pylori).

Gastric cancer (GC) is a prevalent form of cancer, with Helicobacter pylori (H. pylori) infection being the most common risk factor. Recent studies have highlighted the role of long-term irritation of the gastric mucosa caused by bile reflux in the development of cancer. Bile acids (BAs), which are a significant component in bile reflux, have the potential to promote gastric carcinogenesis through various mechanisms. These mechanisms include the induction of intestinal metaplasia (IM), inhibition of H. pylori activity, modification of H. pylori colonization, and alteration of the abundance and composition of microorganisms in the stomach. Defining the mechanism of bile acid-induced gastric carcinogenesis could potentially be an effective approach to prevent GC. Hence, this paper aims to review the mechanism of bile acid-induced IM, the association between BAs and H. pylori infection as well as microorganisms in the stomach, and the correlation between BAs and gastric carcinogenesis. The ultimate goal is to elucidate the role of BAs in the development of GC.

Metabolic syndrome-related SNPs in HLA and TNF7L2 may be risk factors for generalized pustular psoriasis in Chinese Han population.

Background: Generalized pustular psoriasis (GPP) is a rare and severe type of psoriasis. Previous studies have reported that metabolic syndrome and its components have been associated with psoriasis. Objective: To investigate the association of metabolic syndrome-related single-nucleotide polymorphisms (SNPs) and GPP in Chinese Han population. Materials and Methods: One hundred and thirty-six (136) GPP patients and 965 healthy controls were recruited in the study. Approximately, 4 ml peripheral venous blood was collected from each participant. After collection, second-generation sequencing was used to detect genetic polymorphism of 15 SNPs. The plink 1.07 software package was used for statistical analysis. Results: Rs805303 (p = 0.01, OR = 0.70) and rs3177928 (p = 3.18E-07, OR = 2.66) in HLA were significantly different between the two groups. Moreover, rs4506565 (p = 1.41E-03, OR = 2.72) and rs7901695 (p = 9.39E-04, OR = 2.82) in TCF7L2 were significantly associated with GPP in patients without a previous history of PsV. Genotype analysis of rs4506565 and rs7901695 showed that under the recessive model, genotype frequencies of rs4506565 (p = 0.00, OR = 18.52) and rs7901695 (p = 0.00, OR = 18.44) were significantly different between GPP patients and healthy controls. Conclusion: Rs805303 and rs3177928 in HLA may increase the risk of GPP in the Chinese Han population. TCF7L2 may be a risk factor for GPP in patients without a previous history of PsV.

SF1670 inhibits apoptosis and inflammation via the PTEN/Akt pathway and thus protects intervertebral disc degeneration.

OBJECTIVE: Intervertebral disc degeneration (IVDD) is associated with the apoptosis of nucleus pulposus (NP) cells. Previous studies have shown that PTEN plays crucial roles in cell survival and apoptosis. The effect of PTEN inhibitors on cell survival following IVDD has been rarely examined. In this study, we investigated the protective effect of SF1670, as a specific PTEN inhibitor, on an in vitro NP cells degenerated model. PATIENTS AND METHODS: We collected human disc samples from IVDD patients and detected PTEN expression in them with different degenerated degrees. NP cells were isolated from the samples and exposed to IL-1ß with or without SF1670. Then, cells viability was determined by CCK-8 assay. We also measured the levels of collagen II, p16, p53, PTEN, Akt, aggrecan, caspase 3/9, Bax, Bcl-2, and several inflammatory factors in NP cells. RESULTS: We found that the expression of PTEN markedly increased in severely degenerated disc tissues. The data showed that IL-1ß upregulated the expressions of p16, p53, PTEN, caspase 3/9, and Bax, but decreased the expressions of collagen II, Akt, aggrecan, and Bcl-2. Surprisingly, the treatment with SF1670 could significantly reverse the regulatory effects of IL-1ß. Moreover, relative levels of IL-6, IL-8, TNF-α, and MMP3/9/13 were significantly suppressed by SF1670 stimuli compared with IL-1ß group. CONCLUSIONS: Overall, these results demonstrated that SF1670 prevented NP degradation via suppressing apoptosis and inflammation through inhibition of PTEN and activation of Akt. SF1670 may become a novel target for the therapy of IVDD in the future.

S-phase kinase-associated protein-2 (Skp2) promotes nucleus pulposus cell proliferation by inhibition of p27 in attenuating intervertebral disc degeneration.

OBJECTIVE: Nucleus pulposus (NP) cell proliferation plays a key role during the process of intervertebral disc degeneration (IDD). S-phase kinase-associated protein-2 (Skp2) has been proved as an important regulator for cell growth factors in vitro. Nonetheless, whether Skp2 attenuates IDD by mediating NP cell proliferation still remains unclear. Therefore, the aim of this study was to explore how Skp2 affected NP cell proliferation and the potential mechanism in vitro. PATIENTS AND METHODS: In this study, we first collected different degenerated human NP samples and isolated NP cells from these tissues. NP cell degenerated model was established with IL-1ß, and the cells were transfected with lentivirus to achieve Skp2 overexpression. Besides, SKPinC1 was used to suppress Skp2 expression in vitro. Western blot, RT-PCR, and immunocytofluorescence were applied to detect genetic differences among groups. Furthermore, cell viability and cell cycle were determined by CCK-8 assay and flow cytometry, respectively. RESULTS: Skp2 expression decreased significantly in degenerated disc samples (p<0.05). IL-1ß stimulation significantly promoted NP cell degeneration, which could be reversed by Skp2 overexpression (p<0.05). Meanwhile, Skp2 in IDD significantly inhibited the expression level of medial p27 and promoted cell cycle by CDK2 activation (p<0.05). In addition, Skp2 suppression affected NP cell proliferation in vitro. CONCLUSIONS: NP cells exhibited significantly inhibited proliferation ability when down-regulated the expression level of Skp2. Our findings provided a more meritorious viewpoint of Skp2 in NP cell proliferation. Furthermore, the above results suggested that Skp2 was a novel target in the treatment of IDD.

Bio-distribution and anti-tumor efficacy of PEG/PLA nano particles loaded doxorubicin.

As a more effective in vivo drug delivery system, several methods loading anti-cancer drugs to biodegradable and biocompatible nano-particles have been explored and developed. Supposedly due to the enhanced permeability and retention (EPR) effect, systemic administration of these nano-particles have been found to result in accumulation of nano-particles into solid tumors. In this study, we prepared nano-particles using polyethylene glycol (PEG)/poly-L-lactide (PLLA) diblock copolymer and loaded doxorubicin into these nano-particles (Nano-dox). The fabricated nano-particles exhibited sustained release kinetics of the drug in vitro. To follow the in vivo biodistribution of 200-350 nm sized nano-dox particles in tumor (syngenic renal cell adenocarcinoma: RENCA) bearing mouse, the carboxylfluorescenin diacetate succinimidyl ester (CFSE) was loaded into the nano-particles. Nano-dox accumulated preferentially in tumors; however, in terms of its anti-tumor efficacy, it did not show any marked benefits, compared to freely-administered doxorubicin. This result suggests the need to re-consider and evaluate what type of anti-cancer reagents we to be used in the ongoing efforts of coupling drug delivery system with tumor EPR effects.

MicroRNA-122 regulates caspase-8 and promotes the apoptosis of mouse cardiomyocytes.

Cardiomyocyte apoptosis plays key roles in the pathogenesis of heart diseases such as myocardial infarction. MicroRNAs are important regulators of gene expression, which are also involved in the regulation of cardiomyocyte apoptosis. However, cardiomyocyte apoptosis regulated by microRNA (miR)-122 is largely unexplored. The aim of this study focused on the role of miR-122 in cardiomyocyte apoptosis. Cardiomyocytes were isolated from neonatal mice and primarily cultured. MiR-122 mimic and inhibitor were transfected to cardiomyocytes and verified by qRT-PCR. Cell viability and apoptosis post-transfection were assessed by MTT assay and flow cytometry, respectively. Changes in expression of caspase-8 were quantified by qRT-PCR and western blot. Results showed that miR-122 mimic and inhibitor successfully induced changes in miR-122 levels in cultured cardiomyocytes (P<0.01). MiR-122 overexpression suppressed viability and promoted apoptosis of cardiomyocytes (P<0.05), and miR-122 knockdown promoted cell viability and inhibited apoptosis (P<0.05). The mRNA and protein levels of caspase-8 were elevated by miR-122 overexpression (P<0.01) and reduced by miR-122 knockdown (P<0.001). These results suggest an inductive role of miR-122 in cardiomyocyte apoptosis, which may be related to its regulation on caspase-8.

[Studies on the hypoglycemic effect of ginseng polypeptide].

Ginseng polypeptide (GPP) isolated from the root of Panax ginseng C. A. Meyer was demonstrated to decrease the levels of blood sugar and liver glycogen when injected intravenously to rats at doses of 50-200 mg/kg without affecting total blood lipid. when mice were injected subcutaneously daily at doses of 50 and 100 mg/kg for 7 successive days, GPP was also found to decrease blood glucose and liver glycogen. In addition, GPP was found to decrease various experimental hyperglycemia induced by injection of adrenaline, glucose and alloxan. However, GPP exhibited inhibiting effect on the glycogen enhancement induced by glucose, but strengthening effect on the glycogen decrease induced by adrenaline. When the levels of blood total lipid and liver glycogen were increased by alloxan, GPP was shown to inhibit these changes except its lowering of blood sugar. The toxicity of GPP is very low, its iv LD50 for mice was found to be 1.62 +/- 0.130 g/kg.

[Experimental and clinical research of dachengqi decoction in treating post-traumatic respiratory distress syndrome].

UNLABELLED: 12 cases of post-traumatic RDS treated with Dachengqi Decoction were reported. RESULTS: 10 patients survived, which showed a bright prospect for the treatment of post-traumatic RDS. In the experimental study, model of RDS was set up in rabbits. The pressure of PaO2 was determined and the morphologic changes of their lung tissues was observed after the rabbits were perfused with Dachengqi Decoction. The results showed that their PaO2 were markedly increased and lung conditions greatly improved, which provided an experimental basis for RDS with Dachengqi Decoction. Among 12 cases; nine were moderate cases and three serious ones. During the course of treatment with Dachengqi Decoction, two patients died, covering only 16.6% of the total number of patients. This fact confirms the efficacy of Dachengqi Decoction in treating the post-traumatic RDS.
