ABSTRACT

The prognosis of acromelanomas (AM) is worse. The objective of this study was to investigate the clinical features of distant metastasis of AM and the factors affecting the survival and prognosis of patients. In this study, a retrospective study was conducted to select 154 AM patients admitted to Nanjing Pukou People's Hospital from January 2018 to April 2021 for clinical research. The clinical characteristics of distant metastasis were statistically analyzed, and the survival curve was drawn with 5-year follow-up outcomes. The median survival time of the patients was calculated, and the clinicopathological features and peripheral blood laboratory indexes of the surviving and dead patients were analyzed. Logistic regression model was used to analyze the risk factors affecting the prognosis of AM patients. In this study, 154 patients with AM were treated, including 88 males and 76 females, aged from 27 to 79 years old, with an average age of (59.3 ±â€…11.7) years old. Among them, 90 cases had distant metastasis. The main metastatic sites were lung (47.78%) and lymph nodes (42.22%). Among them, single site metastasis accounted for 41.11% and multiple site metastasis 58.89%. 89 cases survived and 65 cases died. The survival time was 22 months to 60 months, and the median survival time was 48.0 months. The Breslow thickness, stage at diagnosis, distant metastasis, site of metastasis and ulceration were compared between the survival group and the death group (P < .05). serum lactate dehydrogenase (LDH), neutrophil-to-lymphocyte ratio (NLR) and lymphocyte monocyte ratio (LMR) were compared between the survival group and the death group (P < .05). The results of Logistic regression model showed that LDH ≥ 281 U/L, NLR ≥ 2.96, LMR ≤ 3.57, newly diagnosed stage > stage II, distant metastasis, multiple site metastasis and tumor ulcer were independent risk factors for poor prognosis of AM patients (P < .05). Patients with AM had a higher proportion of distant metastasis, mainly lung and lymph node metastasis. Increased LDH, increased NLR, decreased LMR, higher initial stage, distant metastasis, multiple site metastasis, and combined tumor ulcer were closely related to the poor prognosis of patients after surgery.

ABSTRACT

In this work, a highly sensitive and selective method for detecting folic acid (FA) was developed using D-penicillamine (DPA) stabilized Ag/Cu alloy nanoclusters (DPA@Ag/Cu NCs). The yellow emission of DPA@Ag/Cu NCs was found to be quenched upon the addition of FA to the system. The fluorescence intensity quenching value demonstrated a linear relationship with FA concentrations ranging from 0.01 to 1200 µM, with a limit of detection (LOD) of 5.3 nM. Furthermore, the detection mechanism was investigated through various characterization analyses, including high resolution transmission electron microscopy, fluorescence spectra, ultraviolet-visible absorption spectra, and fluorescence lifetime. The results indicated that the fluorescence quenching induced by FA was a result of electron transfer from FA to the ligands of DPA@Ag/Cu NCs. The selectivity of the FA sensor was also evaluated, showing that common amino acids and inorganic ions had minimal impact on the detection of FA. Moreover, the standard addition method was successfully applied to detect FA in human serum, chewable tablets and FA tablets with promising results. The use of DPA@Ag/Cu NCs demonstrates significant potential for detecting FA in complex biological samples.

ABSTRACT

Luteolin is a potent anti-colorectal cancer chemical. However, its effectiveness is hindered by its poor solubility in water and fat, and it is easy to degrade by gastrointestinal enzymes. In this study, a nano-composite carrier, NH2-MIL-101(Fe)@GO (MG), based on aminated MIL-101(Fe) and graphene oxide (GO) was developed and evaluated. This carrier co-delivered luteolin and matrine, while marine was used to balance the pH for the nano-preparation. The loading capacities for luteolin and matrine were approximately 9.8% and 14.1%, respectively. Luteolin's release at pH = 5 was significantly higher than at pH = 7.4, indicating it had an acidic pH response release characteristic. Compared to MOF and GO alone, MG and NH2-MIL-101(Fe)@GO@Drugs (MGD) enhanced anti-cancer activity by inhibiting tumor cell migration, increasing ROS generation, and upregulating the expression of Caspase-3 and Caspase-9. In conclusion, this study contributes new ideas and methods to the treatment strategy of multi-component anti-colorectal cancer therapy. It also advances drug delivery systems and supports the development of more effective and targeted treatment approaches for colorectal cancer.

ABSTRACT

Squamous cell carcinoma of the head and neck (SCCHN) is a commonly detected cancer worldwide. Human papillomavirus (HPV) is emerging as an important risk factor affecting SCCHN prognosis. Therefore, identification of HPV status is essential for effective therapies in SCCHN. The aim of this study was to investigate the prognostic value of HPV-associated RNA biomarkers for SCCHN. The clinical data, survival data, and RNA-seq data of SCCHN were downloaded from The Cancer Genome Atlas database. Before the differential expression analysis, the heterogeneity between the 2 groups (HPV+ vs HPV-) of samples was analyzed using principal component analysis. The differentially expressed genes (DEGs) between HPV+ and HPV- SCCHN samples were analyzed using the R edgeR package. The Gene Ontology functional annotations, including biological process, molecular function and cellular component (CC), and Kyoto Encyclopedia of Genes And Genomes pathways enriched by the DEGs were analyzed using DAVID. The obtained matrix was analyzed by weighed gene coexpression network analysis. A total of 350 significant DEGs were identified through differential analysis, and these DEGs were significantly enriched in functions associated with keratinization, and the pathway of neuroactive ligand-receptor interaction. Moreover, 72 hub genes were identified through weighed gene coexpression network analysis. After the hub genes and DEGs were combined, we obtained 422 union genes, including 65 survival-associated genes. After regression analysis, a HPV-related prognostic model was established, which consisted of 8 genes, including Clorf105, CGA, CHRNA2, CRIP3, CTAG2, ENPP6, NEFH, and RNF212. The obtained regression model could be expressed by an equation as follows: risk score = 0.065 × Clorf105 + 0.012 × CGA + 0.01 × CHRNA2 + 0.047 × CRIP3 + 0.043 × CTAG2-0.034 × ENPP6 - 0.003 × NEFH - 0.068 × RNF212. CGA interacted with 3 drugs, and CHRNA2 interacted with 11 drugs. We have identified an 8 HPV-RNA signature associated with the prognosis of SCCHN patients. Such prognostic model might serve as possible candidate biomarker and therapeutic target for SCCHN.

ABSTRACT

AIM:To investigate the changes of retinal microcirculation after phacoemulsification and the influencing factors of visual acuity.METHODS: Retrospective analysis. A total of 264 cataract patients(264 eyes)who underwent phacoemulsification in our hospital from January 2022 to December 2022 were selected as the study objects. Patients were divided into &#x0026;#x003C; 0.3 group(66 eyes)and ≥0.3 group(198 eyes)according to the recovery of best corrected visual acuity(BCVA)at 3 mo after surgery. The changes of retinal microcirculation indexes were compared before and after treatment. Logistic regression and LASSO regression models were used to screen the influencing factors of postoperative BCVA. A nomogram prediction model of postoperative BCVA was constructed and verified. A restricted cubic spline Logistic regression model was established to analyze the dose-response relationship between end-diastolic velocity(EDV), peak systolic velocity(PSV)and the risk of BCVA recovery.RESULTS: At 3 mo postoperatively, EDV and PSV were significantly improved compared with those before treatment, and resistance index(RI)levels were significantly lower than those before treatment(all P&#x0026;#x003C;0.05). Preoperative EDV, PSV, aqueous humor cell grade, fundus lesion grade, advanced age and Emery grade were influencing factors for poor BCVA recovery after phacoemulsification in cataract patients(P&#x0026;#x003C;0.05). The AUC before and after validation of the nomogram model by Bootstrap method were 0.869(95%CI: 0.815-0.903)and 0.866(95%CI: 0.802-0.895), respectively. The sensitivity was 88.36% and 88.27%, and the specificity was 91.82% and 91.78%, respectively. Restricted cubic spline model analysis showed no nonlinear dose-response relationship between EDV and PSV levels and the risk of poor BCVA recovery in either male or female(P&#x0026;#x003E;0.05).CONCLUSION: After phacoemulsification, retinal microcirculation in cataract patients improved significantly. EDV, PSV, aqueous humor cell grade, fundus lesion grade, advanced age and Emery grade are all factors influencing poor BCVA recovery after cataract surgery.

ABSTRACT

In this paper, the antitussive and expectorant activity of platycodin D (PD) were studied by constructing a mouse cough induced by concentrated ammonia water and a mouse trachea phenol red excretion model. The mechanism of antitussive and expectorant effect of PD was studied by metabolomics. The animal experiment was approved by the Animal Ethics Committee of Jiangxi University of Chinese Medicine (approval number: JZLLSC-20220739). Then mice were randomly divided into the normal, model, positive drug, PD low-dose, PD medium-dose and PD high-dose group. The antitussive and expectorant effects of PD were evaluated using a cough mouse model induced by concentrated ammonia water and a mouse tracheal phenol red excretion model, respectively. UHPLC-LTQ-Orbitrap-MS was used to identify the metabolites of mouse lung tissue, and multivariate statistical analysis method of orthogonal partial least squares discriminant analysis (OPLS-DA) was used for metabolites profile analysis. The differential metabolites were screened by variable projected importance value (VIP) and t-test results. Pathways for enrichment of differentiated metabolites were analyzed using the MetaboAnalyst platform. The comparative method was applied to analyze the differences in mechanisms of PD, Deapio-platycodin D (DPD) and total platycosides fraction. The results showed that PD at different concentrations could significantly prolong (P < 0.05) the incubation period of cough mice induced by ammonia water, reduce the coughs frequency, and significantly increase (P < 0.05) the amount of phenol red excretion in phenol red excretion model mice. PD could regulate 6 metabolic pathways of phenylalanine, tyrosine and tryptophan biosynthesis, linoleic acid metabolism, phenylalanine metabolism, glycerophospholipid metabolism, and tyrosine metabolism to exert antitussive effect. It could also regulate 8 metabolic pathways of linoleic acid metabolism, glyoxylic acid and dicarboxylic acid metabolism, glycerol phospholipid metabolism, citric acid cycle and arachidonic acid metabolism to exert an expectorant effect. However, only linoleic acid metabolism and glycerophospholipid metabolism could be regulated by the PD, total platycosides fraction and DPD, which may be ascribed to the structural difference of the platycosides and the interaction between platycosides and the intestinal microbiota. Functional analysis showed that these metabolic pathways are closely related to the regulatory mechanisms of anti-inflammatory response, immune function regulation, neurotransmitter release, cell signal transduction, energy metabolism and cell apoptosis. This study shows that PD possesses good antitussive and expectorant activities. In addition, the mechanism difference of PD, total platycosides fraction and DPD imply that the apiose in PD and the interaction between PD and intestinal microbiota could exert an important effect on the antitussive and expectorant mechanism of the platycosides.

ABSTRACT

AIM:To investigate the effects and mechanisms of curcumin on apoptosis of retinal ganglion cells(RGCs)in chronic ocular hypertension rats.METHODS:A total of 21 Spraque-Dawley(SD)rats were randomly divided into 3 groups with 7 rats in each group. The rat models of chronic ocular hypertension were established by cauterization of the superior scleral veins in the high intraocular pressure model group and the curcumin treatment group, and the sham operation group only cut the conjunctiva without the cauterization of the superior scleral veins; the rats in the curcumin treatment group were intragastrically treated with curcumin at a dose of 4mL/kg, and the rats in the sham operation group and the high intraocular pressure model group were treated with pure water at a dose of 4mL/kg for 3wk. After 3wk, HE staining was used to observe the morphological and pathological changes of retina, the number of RGCs and the thickness of ganglion cell layer(GCL)in each group of rats; TUNEL staining was used to observe the apoptosis of RGCs and retinal cells in each group of rats; the expression levels of glutamate-cysteine ligase modifier subunit(GCLM)and heme oxygenase-1(HO-1)in the retina of each group of rats were detected by real-time fluorescence quantitative PCR, immunohistochemical staining and Western blot.RESULTS:Compared with the sham operation group, the retinal morphology of rats in the high intraocular pressure model group and the curcumin treatment group was disorganized, the number of RGCs was reduced, the GCL was thinner, the apoptosis rate of RGCs and retinal cells increased, and the expression levels of GCLM and HO-1 increased. Compared with the high intraocular pressure model group, the retinal morphology of rats in the curcumin treatment group was basically normal, the number of RGCs increased, the GCL thickened, the apoptosis rate of RGCs and retinal cells decreased, and the expression levels of GCLM and HO-1 increased.CONCLUSION:Curcumin can inhibit the apoptosis of RGCs in the rat model of chronic ocular hypertension by up-regulating the expression of antioxidant genes GCLM and HO-1.

ABSTRACT

Hepatitis B virus (HBV) has the characteristics of wide transmission, a high chronic infection rate, and a low cure rate, and improving the cure rate of HBV may help to improve the long-term prognosis of patients. Heat shock protein 90 (Hsp90) is a chaperone protein widely present in organisms. In recent years, more and more studies have shown that Hsp90 is associated with HBV infection and plays an important role in HBV replication. It can not only interact with specific proteins of the virus to promote its replication, but also interact with the host’s own proteins to perform its function. This article reviews the role of Hsp90 in HBV replication in recent studies, so as to provide new theoretical guidance and directions for the development of new anti-HBV drugs targeting Hsp90 and the prevention and treatment of HBV infection in the future.

ABSTRACT

ObjectiveTo investigate the prevalence of overweight, obesity and fatty liver disease (FLD) in adult residents in a suburban area of Shanghai, and to explore the relationship between these conditions and eating out of home (EOH). MethodsAdult residents from Zhongshan Street, Songjiang, Shanghai, were invited to report their frequency of EOH and undergo a physical examination using B-ultrasonography from May to September 2017. Binary logistic regression analyses were conducted to examine the relationship between EOH and conditions of overweight, obesity, and FLD. ResultsAmong the final sample size of 6 608 participants, the prevalence rates of overweight, obesity, and FLD were 41.65%, 14.71% and 38.29%, respectively. After adjusting for potential confounders, logistic analyses revealed that participants with an EOH frequency > once/week had a 1.44-fold higher prevalence of obesity (P=0.006), a 1.35-fold higher prevalence of overweight/obesity (P=0.005), and a 1.36-fold higher prevalence of FLD (P=0.008). ConclusionThe prevalence of overweight, obesity, and FLD is relatively high in Songjiang, Shanghai. EOH may be a risk factor for these diseases, and residents are recommended to reduce the frequency of EOH.

ABSTRACT

OBJECTIVE@#To investigate the effect of Bushen Chushi decoction combined with platelet-rich plasma(PRP) to treat knee osteoarthritis(KOA) in early and middle stage and its regulation on TGF-β1 and Smad-1 expression in serum.@*METHODS@#Total of 45 patients with KOA in early and middle stage from May 2020 to April 2022 were treated and divided into control group and observation group. In control group, there were 30 patients including 12 males and 18 females, aged from 43 to 69 years old with an average of(57.3±6.5) years old and disease duration ranged from 1.5 to 5.0 years with an average of(3.8±1.7) years, and there were 8 cases in gradeⅠ, 13 cases in gradeⅡ, and 9 cases in grade Ⅲ according to Kellgren-Lawrence Grade, PRP 5 ml was injected into knee joint on the first day of No1, 3 week together for 2 times. In the observation group, there were 15 cases including 7 males and 8 females, aged from 45 to 70 years old with an average of (56.7±6.2) years old and disease duration ranged from 1.8 to 5.7 years with an average of (4.0±1.8) years, there were 4 cases in gradeⅠ, 9 cases in gradeⅡand 4 cases in grade Ⅲ according to the Kellgren-Lawrence Grade, PRP 5 ml were injected into knee joints that the time and frequency were the same as those in the control group, and at the same time Bushen Chushi decoction orally were taken 1 dose per day with a total of 28 doses. All patients were treated for four weeks. Visual analogue scale(VAS) and Lequesne MG score before and after treatment were used to evaluate improvement of knee pain and joint function. The TGF-β1 and Smad-1 levels in serum were measured before and after treatment in two groups. The incidence of complications in two groups was observed.@*RESULTS@#All patients were followed up for 26 to 30 days with an average of (28.0±0.6) days. There was no significant difference in VAS and knee Lequesne MG scores between two groups before treatment(P>0.05). The scores of VAS and knee Lequesne MG on the first day after treatment in both groups were lower than those before treatment(P<0.05). The VAS and knee Lequesne MG scores in observation group were lower than those in control group(P<0.05) on the first day after treatment. The TGF-β1 level in serum after treatment were higher significantly than that before treatment in two groups(P<0.05). After treatment, TGF-β1 level in serum in observation group were lower than those in control group with statistically significant differences(P<0.05). The Smad-1 levels in serum after treatment in observation group were higher significantly than that in control group(P<0.05). The levels of Smad-1 were not statistically significant between before and after treatment(P>0.05). There was no significant difference in postopertaive complications between two groups (P>0.05).@*CONCLUSION@#The efficacy of Bushen Chushi decoction combined with PRP in treatment of early and middle KOA is better than that of PRP injection alone. The combined treatment could reduce TGF-β1 level and increase Smad-1 level in serum, which may be a mechanism to inhibit inflammation and alleviate cartilage degeneration to some extent.

ABSTRACT

Objective: To explore the associations of glycated hemoglobin (HbA1c) with FPG and oral glucose tolerance test 2-hour (OGTT-2 h) in areas at different altitude in China. Methods: Subjects who participated in 2018-2019 China Chronic Disease and Risk Factor Surveillance and had no prior type 2 diabetes diagnosis were included. Subsequently, they were categorized into three groups based on altitude of living area (<2 000, 2 000- and ≥3 000 m). With adjustment for intracluster correlation, multivariable linear regression analysis was performed to evaluate the associations of HbA1c with FPG and OGTT-2 h in the context of HbA1c was normal (<5.7%) or abnormal (≥5.7%). Furthermore, the shape of relationships between HbA1c and glucose indicators was examined using restricted cubic spline. Finally, receiver operating characteristic curve was used to evaluate the diagnostic performance of HbA1c for diabetes. Results: A total of 157 277 subjects were included in the analysis. While FPG and OGTT-2 h levels gradually decreased with increase of altitude, HbA1c level was similar among the three groups. When HbA1c was <5.7%, its association with FPG and OGTT-2 h was weak and no obvious difference was observed among the three groups. When HbA1c was ≥5.7%, the FPG and OGTT-2 h increased by 15.45% (95%CI:14.71%- 16.18%) and 24.54% (95%CI:23.18%-25.91%) respectively per one standard deviation increase in HbA1c in group in area at altitude <2 000 m. However, the FPG and OGTT-2 h increased by 13.08% (95%CI:10.46%-15.76%) and 21.72% (95%CI:16.39%-27.31%), respectively, in group in area at altitude 2 000- m, and increased by 11.41% (95%CI:9.32%-13.53%) and 20.03% (95%CI:15.38%- 24.86%), respectively, in group of altitude ≥3 000 m. The restricted cubic spline indicated that the curve showing the association of HbA1c with FPG and OGTT-2 h was flat when HbA1c was <5.7%, but showed a positive linear relationship when HbA1c was ≥5.7%. The area under curve for detecting diabetes was 0.808 (95%CI:0.803-0.812) in group of altitude <2 000 m and 0.728 (95%CI:0.660-0.796, P=0.022) in group of altitude ≥3 000 m. The relevant optimal cutoff value of HbA1c was 5.7%, with a sensitivity of 65.4% and a specificity of 83.0%, and 6.0%, with a sensitivity of 48.3% and a specificity of 93.7%, respectively. Conclusions: When HbA1c was ≥5.7%, the association between HbA1c and glucose indicators became weaker as the increase of altitude. In the area at altitude ≥3 000 m, it may not be appropriate to use HbA1c in the diagnosis of diabetes.

ABSTRACT

Objective:To summarize and analyze the clinical and genetic characteristics of Chinese patients with adrenomyeloneuropathy (AMN).Methods:Clinical data were collected and analyzed retrospectively on AMN patients who were diagnosed by genetic testing in Shanghai Sixth People′s Hospital, Shanghai Jiao Tong University School of Medicine from May 2008 to August 2022. Clinical characteristics of AMN patients with different types of gene mutations were compared. Loe score was used to evaluate the severity of white matter demyelinating, and the serum levels of very long-chain fatty acids (VLCFA) in patients with or without white matter demyelinating were compared. The motor function of the AMN patients was assessed using the Expanded Disability Status Scale (EDSS), and the association between EDSS scores and the course of disease was analyzed.Results:A total of 23 male patients with onset age of (29.52±9.91) years were included in this study. The first symptom of all patients was abnormal lower extremities, of which 17 patients showed stiffness and weakness in their lower limbs (73.9%, 17/23), and 6 patients showed numbness and pain in both lower limbs (26.1%, 6/23). The occurrence of symptoms was not related to the type of gene mutation. White matter demyelination occurred in 33.3% (7/21) of patients over a disease duration of (7.67±4.46) years. There was no statistically significant difference in serum VLCFA level between the white-matter demyelination group and the non-demyelination group. The EDSS score was positively correlated with the disease duration ( r=0.57, P=0.006). Sixteen ABCD1 gene mutations were found in this study, among which c.5_19delinsTCTCCAGG (p.P2Lfs *12) was reported for the first time. Four probands belonging to different families carried the c.1415_1416del (p.Q472Rfs *83) variant. Conclusions:Lower limb movement disorders and sensory dysfunction are the prominent clinical manifestations in AMN patients, with deterioration of motor function associated with the course of disease. AMN may be converted to cerebral type and VLCFA concentration is not associated with the phenotypic changes. The c.1415_1416del (p.Q472Rfs *83) mutation is a hot spot mutation of the disease.

ABSTRACT

Objective:To assess the prevalence of metabolic syndrome(MS) and its relationship with hyperuricemia(HUA) in perimenopausal women in Anning city, Yunnan province.Methods:This is a cross-sectional survey. In May 2021, a multi-stage stratified sampling method was used to collect demographics and clinical data [ethnicity, living community, height, weight, waist circumference, blood pressure, fasting plasma glucose, triglycerides(TG), serum uric acid, high density lipoprotein-cholesterol(HDL-C), alanine transaminase(ALT), etc] in a total of 6 721 perimenopausal women aged 45-60 years.Results:A total of 6 721 perimenopausal women were included in this study. The prevalences of MS and HUA were 14.05%(95% CI 13.22%-14.88%) and 6.46%(95% CI 5.88%-7.07%), respectively. The average age, HDL-C, urea, direct bilirubin, and albumin levels in the perimenstrual HUA population were lower than those in the non-HUA population while the levels of TG, ALT, heart rate, body mass index(BMI), and creatinine were higher(all P<0.05). The prevalence of HUA in perimenopausal women with ethnic minorities and family history of chronic diseases was higher than that in Han nationality and without family history of chronic diseases. The prevalence of MS in perimenopausal women was increased with the increase of serum uric acid( Z=-15.313 8, P<0.001). Multivariate logistic regression model showed that HUA was positively correlated with MS( OR=1.526, 95% CI 1.192-1.954) after adjusting for covariates such as BMI and ethnicity, and the incidence of MS in perimenopausal women in HUA group was 1.526 folds higher than that in non-hyperuricemia group. Conclusion:HUA is highly positively correlated with MS in perimenopausal women. The management of uric acid level in perimenopausal women should be strengthened.

ABSTRACT

Objective:This study aimed to investigate the effect of lipohypertrophy induced by insulin injection on blood glucose fluctuation in patients with type 1 diabetes mellitus.Methods:A total of 80 patients with type 1 diabetes mellitus were recruited between June 2021 and December 2021 from the First Affiliated Hospital of Nanjing Medical University. And these patients all received insulin injection more than six months. Lipohypertrophy was assessed by ultrasound scanning, and blood glucose fluctuation was evaluated using the flash glucose monitoring system(FGM). Univariate analysis and multivariate linear regression were used to analyze the relationship of lipohypertrophy and and core indicators of blood glucose fluctuation.Results:Compared with patients without lipohypertrophy, patients with lipohypertrophy had higher mean amplitude of glycemic excursions(MAGE), coefficient of variation(CV), mean of daily differences(MODD), standard deviation(SD) of blood glucose, time above range(TAR), and high blood glucose index(HBGI; all P<0.05), while time in range(TIR) of glucose markedly become lower( P<0.01). Moreover, multivariate linear regression analysis showed that lipohypertrophy detected by ultrasound was an independent influencing factor of TIR( β=-9.423, P=0.032), MAGE( β=1.114, P=0.039), CV( β=4.304, P=0.041), MODD( β=0.717, P=0.046) after adjusting for age at diagnosis, duration of insulin injection, fasting C-peptide, and daily dose of insulin per unit weight. Conclusion:Lipohypertrophy increases glycemic variability and imposes negative impact on glycemic control rate in patients type 1 diabetes mellitus.

ABSTRACT

Objective:To discuss the effect of remnant cholesterol (RC) levels on carotid intima thickness (CIT) in patients with type 2 diabetes mellitus (T2DM) by ultra-high frequency ultrasound.Methods:A total of 60 patients with T2DM who received treatment in Henan Provincial People′s Hospital from May 2021 to July 2022 were prospectively recruited, and they were divided into a higher RC group (31 cases) and a lower RC group (29 cases) according to the RC levels. Thirty-one age, sex and body mass index(BMI)-matched healthy volunteers were selected as control group. Carotid CIT, carotid media thickness(CMT) and intima-media thickness(CIMT) were measured by 24 MHz ultra-high frequency ultrasound probe. The difference of general clinical data, laboratory indicators and CIMT, CIT, CMT among the three groups were compared, and the influencing factors of CIT in T2DM patients were explored by multivariate regression analysis.Results:①There were no statistical significances in gender, age, BMI, high-density lipoprotein cholesterol (HDL-C) and CMT among the three groups (all P>0.05). There were no statistical significances in duration of diabetes, fasting blood-glucose and glycated haemoglobin between the two subgroups of T2DM (all P>0.05). ②Compared with the control group, CIMT and CIT were thicker in the T2DM group (both P<0.05). ③CIT was thicker in the higher RC group than in the lower RC group ( P<0.05), while the difference of CIMT was not statistically significant the two groups ( P>0.05). ④Multivariate regression analysis showed that RC was the influence factor of CIT in patients with T2DM(β=0.610, P=0.005). Conclusions:CIT is significantly thicker in T2DM patients with higher RC than in those with lower RC, and RC is the influence factor of CIT, which suggests that more attention should be paid to the detection of RC in T2DM patients.

ABSTRACT

The automation of traditional Chinese medicine(TCM)pharmaceuticals has driven the development of process analysis from offline to online.Most of common online process analytical technologies are based on spectroscopy,making the identification and quantification of specific ingredients still a challenge.Herein,we developed a quality control(QC)system for monitoring TCM pharmaceuticals based on paper spray ionization miniature mass spectrometry(mini-MS).It enabled real-time online qualitative and quantitative detection of target ingredients in herbal extracts using mini-MS without chromatographic separation for the first time.Dynamic changes of alkaloids in Aconiti Lateralis Radix Praeparata(Fuzi)during decoction were used as examples,and the scientific principle of Fuzi compatibility was also investigated.Finally,the system was verified to work stably at the hourly level for pilot-scale extraction.This mini-MS based online analytical system is expected to be further developed for QC applications in a wider range of pharmaceutical processes.

ABSTRACT

Objective:To investigate the ego-depletion level of adolescents with type 1 diabetes mellitus (T1DM) and to explore its association with glycemic control and quality of life.Methods:This was a cross-sectional survey study. A total of 195 adolescents with T1DM were recruited from the First Affiliated Hospital of Nanjing Medical University from March to September 2022 by convenient sampling method. The Self-Regulatory Fatigue Scale (SRF-S) and Short Form of the Chinese version Diabetes Quality of Life for Youth Scale (C-DQOLY-SF) and the general information questionnaire were collected and the glycated hemoglobin (HbA 1c) value was detected. Results:The total score of self-regulatory fatigue for 195 adolescents with T1DM was (42.23 ± 9.94) points, with a scoring rate of 52.79%, which was at a medium level. Pearson correlation analysis showed that the total score of self-regulatory fatigue was positively correlated with HbA1c ( r = 0.25, P<0.01), and negatively correlated with quality of life ( r = -0.61, P<0.01). The hierarchical linear regression results showed that after controlling for demographic sociolagy and disease variables, ego-depletion had a positive predictive effect on HbA1c ( t = 3.69, P<0.01), while ego-depletion had a negative predictive effect on Quality of life ( t = -8.48, P<0.01). Conclusions:Ego-depletion of adolescents with T1DM may affect their blood glucose control and quality of life, which should be noticed by medical workers.
