ABSTRACT

An UHPLC-Q-exactive orbitrap MS method for the simultaneous determination of 19 chemical components in Qilong Zhuang'er oral liquid was established and the quality differences between different batches of samples was compared by chemometric analysis to provide a basis for the quality evaluation of the preparation. The contents of allantoin, L-proline, pyroglutamic acid, hordenine, adenosine, L-phenylalanine, guanosine, L-tryptophan, caffeic acid, calycosin-7-glucoside, verbascoside, isoacteoside, ononin, calycosin, 3-hydroxy-9,10-dimethoxyptercarpan, formononetin, atractylenolide III, atractylenolide II and astragaloside A were analyzed by cluster heat map, principal component analysis (PCA) and partial least squares discriminant analysis (PLS-DA) using Hiplot platform and MarkerlynxXS software to comprehensively evaluate the quality difference of different batches of Qilong Zhuang'er oral liquid. The 19 chemical compounds showed good linearity in their respective concentration ranges (r ≥ 0.999). The RSD of precision, repeatability and stability (24 h) tests were all less than 1.94%. The average recovery was 97.24%-102.75% (RSD < 2.74%, n = 6). The 10 batches of samples were divided into two categories by cluster heat map and PCA analysis. 3-Hydroxy-9,10-dimethoxyptercarpan, atractylenolide III, calycosin, atractylenolide II, formononetin, allantoin and caffeic acid were identified as differential markers by PLS-DA. The established multi component quantitative method of Qilong Zhuang'er oral liquid combined with chemometric analysis can provide reference for the quality evaluation of the preparation.

ABSTRACT

Objective: To evaluate the effect of Wendler Glottoplasty to elevate vocal pitch in transgender women. Methods: The voice parameters of pre-and 3-month post-surgery of 29 transgender women who underwent Wendler Glottoplasty in department of otorhinolaryngology head and neck surgery of Beijing Friendship Hospital from January, 2017 to October, 2020 were retrospectively analyzed. The 29 transgender women ranged in age from 19-47 (27.0±6.3) years old. Subjective evaluation was performed using Transsexual Voice Questionnaire for Male to Female (TVQMtF). Objective parameters included fundamental frequency (F0), highest pitch, lowest pitch, habitual volume, Jitter, Shimmer, maximal phonation time (MPT), noise to harmonic ratio (NHR) and formants frequencies(F1, F2, F3, F4). SPSS 25.0 software was used for statistically analysis. Results: Three months after surgery, the score of TVQMtF was significantly decreased [(89.9±14.7) vs. (50.4±13.6), t=11.49, P<0.001]. The F0 was significantly elevated [(152.7±23.3) Hz vs. (207.7±45.9) Hz, t=-6.03, P<0.001]. Frequencies of F1, F2 and F3 were significantly elevated. No statistical difference was observed in the frequencies of F4. The highest pitch was not significantly altered while the lowest pitch was significantly elevated [(96.8±17.7) Hz vs. (120.0±28.9) Hz, t=-3.71, P=0.001]. Habitual speech volume was significantly increased [(60.0±5.2) dB vs. (63.6±9.6) dB, t=-2.12, P=0.043]. Jitter, Shimmer, NHR and MPT were not obviously altered (P>0.05). Conclusions: Wendler Glottoplasty could notably elevate the vocal pitch, formants frequencies and degree of vocal femininity in transgender women without affecting phonation ability and voice quality. It can be an effective treatment modality for voice feminization.

ABSTRACT

Objective: Single-cell RNA sequencing (scRNA-seq) was used to analyze the developing mouse molars, in order to construct a spatiotemporal development atlas of pulp cells, and further to reveal the developmental process and regulatory mechanism of tooth development. Methods: Ten mandibular first molars from C57BL/6 mice in postnatal day (PN) 0 and 3 were respectively dissected and digested to obtain single-cell suspensions. scRNA-seq was performed on 10× Genomics platform. PN 7 mouse molar scRNA-seq data were obtained from our previous study. PN 0, 3, and 7 scRNA-seq data were integrated for following analysis. The initial quality control, mapping and single cell expression matrix construction were performed by Cell Ranger. Quality control, standardization, dimensional reduction and cluster analysis were performed by using Seurat. Monocle was used to generate the pseudotime trajectory. Scillus was used to perform gene ontology analysis. In order to detect the spatiotemporal change of different population of pulp cells, the marker genes of each cluster were demonstrated by RNAscope in situ hybridization. Results: There were twenty-six cell clusters within mouse molars, which were identified as eight different cell types, including dental pulp cells, dental follicle cells, epithelial cells, immune cells, endothelial cells, perivascular cells, glial cells and erythrocytes. We further re-clustered and analyzed dental pulp cells. Cluster 0 were mature pulp cells, which located at the upper portion of crown. The main functions of cluster 0 were osteogenesis and extracellular structure organization. Cluster 1 were apical papilla cells, which located at the apical part of roots, whose main functions were extracellular structure organization and organ development. Cluster 2 were cycling cells, which were actively proliferated, resided in the lower portion of the crown. Cluster 3 and 4 were preodontoblasts and odontoblasts, respectively. Their functions were closely related to biomineralization. The proportion of mature pulp cells increased with the development process, while the proportion of cycling cells and odontoblast lineage decreased. According to the expression pattern of marker genes of each cluster, we constructed a cell atlas of dental pulp. Pseudotime trajectory analysis found there were two development trajectories within dental pulp. They both started from SPARC related modular calcium binding 2 (Smoc2)+ dental papilla cells, then went through DNA topoisomerase Ⅱ alpha (Top2a)+ cycling cells, and finally divided into coxsackie virus and adenovirus receptor (Cxadr)+ mature pulp cells or dentin sialophosphoprotein (Dspp)+ odontoblasts two lineages. Conclusions: scRNA-seq could fully discover the intercellular heterogeneity of cells on transcriptome level, which provides a powerful tool to study the process and regulatory mechanism of organ development.

ABSTRACT

@#Objective To understand the prevalence of smoking and drinking among residents ≥ 30 years old in Chengdu, and to investigate the death attributable to smoking and drinking and its effect on life expectancy. Methods The data sources were data of the causes of death of residents in the 2018 Sichuan Health Statistical Yearbook, the health survey data of Chengdu residents in the natural population cohort in southwest China, and the data of smoking and drinking related diseases and their relative risk in the global disease burden of the World Health Organization. The counterfactual attribution method was used to calculate the number of attributable deaths and life expectancy loss caused by smoking and drinking. Results The life expectancy of 30-year-old residents in Chengdu was 53.91 years (51.52 years for males and 56.48 years for females). The total number of deaths attributed to smoking was 14 370, with chronic obstructive pulmonary disease (4 926), lung cancer (4 234), and esophageal cancer (1 578) ranking the top three. The total number of deaths attributed to drinking was 2 185, among which cerebrovascular disease, esophageal cancer, and liver cirrhosis were the three leading causes of death attributable to drinking. The loss of life expectancy caused by smoking was 2.03 years (3.47 years for males and 0.39 years for females), and the loss caused by drinking was 0.28 years (0.48 years for males and 0.04 years for females). Conclusion Smoking and drinking cause a great loss of life expectancy of Chengdu residents and impose a huge disease burden on the death from respiratory system, digestive system, cardiovascular and cerebrovascular diseases.

ABSTRACT

Objective:To investigate the effect of recombinant lipoproteins of Brucella outer membrane protein 16, 19 (L16 and L19) on the expression of immune regulatory factors in human monocytic leukemia cell line (THP-1 cells). Methods:THP-1 cells activated with phorbol ester (PMA) were used as an in vitro experimental cell model, and a group design was used to co-culture L16, L19 and THP-1 cells (L16 stimulated group, L19 stimulated group), respectively. THP-1 cells activated with PMA were used as the control group. When co-cultured for 4 hours, immunofluorescence staining (IFS) and Western blotting were used to detect whether L16 and L19 entered the cells, respectively; when co-cultured for 12, 24 hours, real-time fluorescent quantitative PCR was used to measure the mRNA expression levels of interferon regulatory factor 1 (IRF-1) and trans activator protein of major histocompatibility complex class Ⅱ (CⅡTA); Western blotting was used to detect the protein expression levels of T cell immunoglobulin mucin-3 (Tim-3) and γ interferon receptor 1 (IFNGR1). Results:When co-cultured for 4 hours, L16 and L19 were observed entering THP-1 cells in the L16 stimulated group and L19 stimulated group, respectively. When co-cultured for 12 hours, the expression level of IRF-1 mRNA in the L16 stimulated group (0.16 ± 0.15) was significantly lower than that in the control group (1.00 ± 0.00, P < 0.05). When co-cultured for 24 hours, the expression level of CⅡTA mRNA in the L16 stimulated group (0.17 ± 0.10) was significantly lower than that in the control group (1.00 ± 0.00, P < 0.05). When co-cultured for 12 and 24 hours, there were no statistically significant differences in the expression levels of IRF-1 and CⅡTA mRNA between the L19 stimulated group and the control group ( P > 0.05). Western blotting results showed that there were statistically significant differences in the expression levels of INFGR1 and Tim-3 protein among the control group, L16 stimulated group, and L19 stimulated group after co-cultured for 12 and 24 hours ( F = 50.92, 6.80, 148.73, 156.57, P < 0.05). Among them, when co-cultured for 12 hours, the expression level of INFGR1 protein in the L16 and L19 stimulated groups were significantly lower than that in the control group, and the L19 stimulated group was higher than the L16 stimulated group ( P < 0.05), and the expression level of Tim-3 protein in the L19 stimulation group was higher than that in the control group ( P < 0.05). When co-cultured for 24 hours, the expression level of INFGR1 protein in the L16 and L19 stimulated groups were lower than that in the control group, and the L19 stimulated group was higher than that in the L16 stimulated group ( P < 0.05); and the expression level of Tim-3 protein in the L16 stimulated group was higher than that in the control group and L19 stimulated group ( P < 0.05). Conclusions:Brucella L16 can downregulate the expression levels of IRF-1 and CⅡTA mRNA in THP-1 cells. Both L16 and L19 can downregulate IFNGR1 and upregulate Tim-3 protein expression levels.

ABSTRACT

OBJECTIVE@#To observe the clinical efficacy of targeted sealing with high viscosity bone cement and secondary injection of low viscosity bone cement in the treatment of OVCFs patients with the fracture lines involved vertebral body margin.@*METHODS@#The elderly patients who underwent vertebroplasty for osteoporotic vertebral compression fractures from January 2019 to September 2021 were selected as the screening objects. Through relevant standards and further CT examination, 56 patients with fracture lines involving the anterior wall or upper and lower endplates of the vertebral body were selected for the study. There were 21 males and 35 females, aged from 67 to 89 years old with an average of (76.58±9.68) years. All 56 patients underwent secondary injection of bone cement during operation. Only a small amount of high viscosity cement was targeted to seal the edge of the vertebral body for the first time, and low viscosity cement was injected to the vertebral bodies during second bolus with well-distributed. The operation time, bone cement volume and bone cement leakage were recorded, and the pain relief was evaluated by visual analogue scale (VAS).@*RESULTS@#All patients were followed up for more than 3 months and the surgeries were successfully complete. The operation time was (50.41±10.30) min and the bone cement volume was (3.64±1.29) ml. The preoperative VAS was (7.21±2.41) points, which decreased significantly to (2.81±0.97) points 3 days after operation(P<0.05). Among the 56 patients, 2 cases(3.57%) had bone cement leakage, 1 case leaked to the paravertebral vein, and 1 case slightly bulged to the paravertebral through the crack when plugging the vertebral crack. Both patients had no obvious clinical symptoms.@*CONCLUSION@#In vertebroplasty surgery, targeted sealing of high viscosity bone cement and secondary injection of low viscosity bone cement can reduce intraoperative bone cement leakage and improve the safety of operation.

ABSTRACT

ObjectiveTo observe the effect of bilateral sequential repetitive transcranial magnetic stimulation on the motor function of upper limbs in stroke patients. MethodsFrom December, 2020 to December, 2022, 62 stroke inpatients in the Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine were included. They were randomly divided into control group (n = 31) and observation group (n = 31). Both groups accepted conventional medicine and rehabilitation, as well as electroacupuncture antagonistic muscle therapy. Before electroacupuncture, the observation group acceped low-frequency repetitive transcranial magnetic stimulation at primary motor cortex (M1) on the healthy side, followed by intermittent theta burst stimulation at M1 on the affected side, for four weeks. They were assessed with Fugl-Meyer Assessment-Upper Extremities (FMA-UE), modified Barthel Index (MBI) and modified Ashworth Scale (MAS), and motor evoked potential (MEP) latency was compared before and after treatment. ResultsOne patient dropped down in the observation group, and no adverse event happened. After treatment, the scores of FMA-UE and MBI significantly increased (|t| > 9.953, P < 0.001), and the score of MAS and the latency of MEP significantly decreased (|t| > 5.043, P < 0.001) in both groups; while all of them were better in the observation group than in the control group (|t| > 2.237, P < 0.05). ConclusionBilateral sequential repetitive transcranial magnetic stimulation can effectively promote the recovery of upper limb motor function in stroke patients.

ABSTRACT

Based on the idea of multi-target drug design, taking p-aminosalicylic acid (PAS) as the parent nucleus, the unreported target molecules TM1 and TM2 were designed with PAS, isonicotinic acid and fluoroquinolone as three structural units conjugated by different linkers. Sixteen target molecules were synthesized by multi-step reaction, and their activities against Mycobacterium tuberculosis and human pathogenic bacteria were evaluated. The results showed that the anti-tuberculosis activity of TM2a was stronger than those of the assayed fluoroquinolones, while TM1a was comparable to that of clinafloxacin, the most active compound of the positive control fluoroquinolones; TM1a showed the strongest inhibitory activity to all almost tested strains, TM1b and TM2a showed very strong inhibitory activity to most strains, and TM1h/2h had strong inhibitory activity to some strains; The inhibitory activities of TM1a/1h on Staphylococcus aureus ATCC14125 are much stronger than those of fluoroquinolones, which eminently deserves further study. The hemolysis test results showed that the highly active molecules TM1a and TM2a exhibited relative safety below the concentrations of 8 and 32 μg·mL-1, respectively. In this study, a new hybrid molecule of three molecular pharmacophores with PAS as the parent nucleus was synthesized for the first time, and some of which have highly strong antibacterial activity, which provides a new idea for the research and development of antibiotics.

ABSTRACT

Objective:To investigate the relationship between rapid eye movement sleep behavior disorder(RBD)and neurofilament light chain(NfL)levels in patients with Parkinson's disease(PD).Methods:General clinical data of 121 PD patients and 38 healthy controls(HC)who visited the Department of Geriatric Neurology of the First Affiliated Hospital of Kunming Medical University from June 2019 to January 2021 were collected in a prospective study.According to the Rapid Eye Movement Sleep Behavior Disorder Questionnaire(RBDSQ), PD patients were divided into a PD with RBD group(PD-RBD, RBDSQ≥6)and a PD without RBD group(PD-NRBD, RBDSQ<6). General clinical data and plasma NfL levels of patients in the groups were compared.In addition, symptoms during exercise, during non-exercise, and sleep quality in the groups were also compared.Results:Plasma NfL levels were higher in the PD group than in the HC group(19.39 ng/L, 12.58-31.78; 14.85 ng/L, 9.78-22.15; Z=-2.492, P<0.05); plasma NfL levels were significantly higher in the PD-RBD group than in the PD-NRBD group and in the HC group(25.29 ng/L, 19.09-34.75; 17.14 ng/L, 11.70-26.67; 14.85 ng/L, 9.78-22.15; Z=-3.434, P<0.01); there was no significant difference in plasma NfL levels between the HC group and the PD-NRBD group( P>0.05). Receiver operating characteristic(ROC)curve analysis showed that, when the plasma NfL cutoff was set at 17.86 ng/L, PD-RBD and PD-NRBD could be distinguished( AUC=0.70, 95% CI=0.60-0.80, sensitivity 82%, specificity 54%). Binary logistic regression identified NfL level as an independent predictor of PD-RBD( β=0.068, OR=1.103, P=0.003). Conclusions:PD-RBD patients have increased plasma NfL levels, which can potentially serve as a biomarker for PD with RBD.

ABSTRACT

Objective:To investigate the correlation between serum C1q/tumor necrosis factor-associated protein 3 (CTRP3), soluble growth stimulation expression gene 2 protein (sST2), Elabela and prognosis in patients with acute ST-segment elevation myocardial infarction (ASTEMI) after percutaneous coronary intervention (PCI).Methods:The clinical data of 118 ASTEMI patients underwent PCI from March 2019 to March 2021 in Beijing Luhe Hospital, Capital Medical University were retrospectively analyzed. According to whether major adverse cardiovascular events (MACE) occurred within 90 d, the patients were divided into MACE group (36 cases) and non-MACE group (82 cases). The levels of CTRP3, sST2 and Elabela were detected by enzyme linked immunosorbent assay, and the patients were divided into high CTRP3 group and low CTRP3 group, high sST2 group and low sST2 group, high Elabela group and low Elabela group according to the median, there were 89 cases in each group. MACE was the end point event. Kaplan-Meier survival curve was drawn, and compared by log-rank test. Multivariate Cox regression was used to analyze the influencing factors of MACE after PCI in patients with ASTEMI. Receiver operating characteristic (ROC) curve was drawn to analyze the prediction efficiency of MACE.Results:The sST2 in MACE group was significantly higher than that in non-MACE group: (49.56 ± 17.67) μg/L vs. (30.76 ± 12.83) μg/L, the CTRP3 and Elabela were significantly lower than those in non-MACE group: (0.82 ± 0.42) μg/L vs. (2.02 ± 0.58) μg/L and (17.66 ± 3.85) μg/L vs. (21.84 ± 3.18) μg/L, and there were statistical differences ( P<0.01). The incidence of MACE in low CTRP3 group was significantly higher than that in high CTRP3 group: 49.15% (29/59) vs. 11.86% (7/59), the incidence of MACE in lowe Elabela group was significantly higher than that in high Elabela group: 42.37% (25/59) vs. 18.64% (11/59), and there were statistical differences ( χ2 = 19.35 and 7.84, P<0.01); the incidence of MACE in high sST2 group was significantly higher than that in low sST2 group: 38.98% (23/59) vs. 22.03% (13/59), and there was statistical difference ( χ2 = 4.00, P<0.05). The time from admission to MACE was defined as the survival time. Kaplan-Meier survival curve analysis result showed that the survival time in high CTRP3 group was significantly longer than that in low CTRP3 group: (81.02 ± 3.23) d vs. (56.31 ± 4.74) d, the survival time in low sST2 group was significantly longer than that in high sST2 group: (74.52 ± 3.87) d vs. (61.12 ± 5.07) d, the survival time in high Elabela group was significantly longer than that in low Elabela group: (77.95 ± 3.48) d vs. (58.64 ± 4.89) d, and there were statistical differences ( P<0.05). Multivariate Cox regression analysis result showed that the LVEF, TnI, CTRP3, sST2 and Elabela were independent influencing factors of MACE after PCI in patients with ASTEMI ( HR = 1.632, 1.124, 0.712, 1.482 and 0.676; 95% CI 1.531 to 3.271, 1.012 to 1.482, 0.547 to 0.842, 1.063 to 1.852 and 0.536 to 0.725; P<0.01). ROC curve analysis result showed that the cut-off values of CTRP3, sST2 and Elabela in prediction MACE after PCI in patients with ASTEMI were 0.79, 52.17 and 16.82 μg/L respectively, areas under curve were 0.833, 0.732 and 0.739 respectively. Conclusions:CTRP3, sST2 and Elabela can be used as indicators to predict the early prognosis of ASTEMI patients after PCI.

ABSTRACT

Objective:To observe the effect of the new fixation tape on the prevention of pressure injury of the transnasal three-chamber feeding tube.Methods:Using the convenient sampling method, 60 inpatients with indwelling triple-lumen feeding tube from May 2019 to August 2021 in Ward 1 of Gastrointestinal Oncology Center of Peking University Cancer Hospital were selected and divided into two groups by block randomization, 30 patients in each group. The patients in the control group used conventional adhesive tape to fix the three chamber feeding tube, and the patients in the test group used new adhesive tape to fix the three-chamber feeding tube; the two groups were compared in terms of nasal pressure injury, pain, nasal friction and sleep.Results:The incidence rate of nasal pressure injury, nasal pain, nasal rubbing and difficulty falling asleep were 70.00%(21/30), 73.33%(20/30), 66.67%(20/30) and 43.33%(13/30) higher in the control group than 16.67%(5/30), 13.33%(4/30), 23.33%(7/30) and 10.00%(3/30) in the test group, and the difference was statistically significant ( χ2 values were 8.52-22.45, all P<0.05). Conclusions:The use of the new adhesive tape to fix the three-chamber feeding tube can effectively prevent nasal pressure injury and thus reduce pain, improve the patients′ nasal comfort, improve the difficulty falling asleep caused by the transnasal cannula and facilitate the patients′ postoperative recovery.

ABSTRACT

Postmenopausal osteoporosis (PMOP) is a systemic disease characterized by increased bone fragility caused by insufficient estrogen secretion in women after menopause,resulting in decreased bone mass and damage to the microstructure of bone tissues. The main clinical manifestations are low back pain,osteoporotic fractures,spinal deformities,and multiple organ dysfunction. PMOP directly leads to high morbidity, high mortality, and a decline in the quality of life. In addition to miss diagnosis, it is often not treated in time. In recent years, significant progress has been made in the research on factors related to the pathogenesis of PMOP. Based on the previous findings in recent years,this article described three major pathogenesis of PMOP, including intestinal flora imbalance,oxidative stress,and abnormal differentiation of bone marrow mesenchymal stem cells (BMMSCs), and analyzed the current status of PMOP treatment, such as syndrome differentiation and treatment,acupuncture and moxibustion,exercise therapy, and external treatment in traditional Chinese medicine (TCM), and basic measures,drug intervention,and physical therapy in western medicine. Among them,drug intervention in western medicine treatment is generally divided into bone resorption inhibitors,bone formation promoters,and other mechanism drugs according to the mechanism of action. This article summarized the specific methods and effects or mechanisms of TCM and western medicine in the clinical treatment of PMOP,which is expected to provide a reference for formulating reasonable health management models and drug treatments in the future.

ABSTRACT

Objective:To analyze the factors influencing prognosis of intrahepatic cholangiocarcinoma (ICC) after surgical resection.Methods:The clinical data of patients diagnosed with ICC and who underwent surgical resection from December 2015 to December 2019 at the Fifth Medical Center of PLA General Hospital were retrospectively analyzed. Of 39 patients who were included in this study, there were 23 males and 16 females, with age of (54.1±7.2) years old. The body mass index, hepatitis B virus infection status, tumor diameter, degree of differentiation, microvascular tumor thrombus, lymph node metastasis, and serum levels of carbohydrate antigen 19-9 (CA19-9) were analyzed as risk factors affecting postoperative recurrence and survival.Results:The median times to recurrence were significantly better in patients with a tumour length <5 cm (11 vs. 5 months), patients without microvascular tumor thrombus (54 vs. 6 months) and patients without lymph node metastasis (8 vs. 5 months) (all P<0.05). The median survival of patients with CA19-9≥100 U/ml was significantly shorter than that of patients with CA19-9<100 U/ml, (9 vs. 27 months, P<0.05). Tumor diameter>5 cm, microvascular tumor thrombus, lymph node metastasis, and CA19-9 ≥100 U/ml are risk factors affecting the recurrence time after ICC resection, CA19-9 ≥100 U/ml is a risk factor affecting survival time after ICC resection. Conclusion:Tumor diameter, microvascular tumor thrombus, lymph node metastasis and CA19-9 can be used to estimate the risk of ICC recurrence, and CA19-9 level can be used to estimate postoperative survival of ICC patients after resection.

ABSTRACT

Older adults have decreased control of body balance with aging and are prone to fall. As the primary point of contact between human body and ground, footwear is critical for stability of older adults. The relationship between shoe characteristics and stability of older adults was systematically reviewed to determine the effect of footwear characteristics on stability of older adults. The results show that wearing shoes with shoelaces or velcro, low heels, wide outsole and appropriate soles, or using vibrating insoles and arch support insoles can help older adults improve their stability. Excessive sole spring and low sole hardness may have adverse effects on stability of older adults. This study can provide theoretical references for older adults to choose shoes reasonably and for the manufacturers to design and make shoes to prevent falls.
