ABSTRACT
OBJECTIVE To evaluate the cost-effectiveness of ivabradine in the treatment of chronic heart failure （CHF） in the context of “Quadruple Therapy” from the perspective of the health system. METHODS Based on real-world cohort data， the Markov model was constructed according to the natural progression of CHF， with a cycle time of 3 months， a study timeframe of 20 years， and a discount rate of 5%. Using quality-adjusted life year （QALY） and incremental cost-effectiveness ratios （ICER） as the output indexes， the cost-utility analysis was used to evaluate the cost-effectiveness of ivabradine in combination with the “Quadruple Therapy” regimen， compared with the “Quadruple Therapy” regimen for the treatment of CHF， and the robustness of the results of the base analysis was verified by univariate sensitivity analysis and probabilistic sensitivity analysis. RESULTS The results of the base analysis showed that the ICER of ivabradine combined with the “Quadruple Therapy” regimen was 165 065.54 yuan/QALY， compared with the “Quadruple Therapy” regimen， which was lower than the willingness-to-pay （WTP） threshold （257 094 yuan/QALY） based on 3 times of China’s gross domestic product （GDP） per capita in 2022. The results of the univariate sensitivity analysis showed that the discount rate had the greatest impact on the robustness of the model. The probabilistic sensitivity analysis showed that the probability that the ivabradine combined with the “Quadruple Therapy” regimen was cost-effective under the WTP threshold in this study was 59.50%. CONCLUSIONS When using 3 times China’s 2022 GDP per capita （257 094 yuan/ QALY） as the WTP threshold， the combination of ivabradine and the “Quadruple Therapy” regimen for treating CHF is cost- effective.
ABSTRACT
Aim To investigate whether alisol A (AA) could improve the blood brain barrier (BBB) mediated cortex cerebral ischemia-repeifusion injury (CIRI) by inhibiting matrix metalloproteinase 9 (MMP-9). Methods The global cerebral ischemia- reperfusion (GCI/R) model in mice was established, and the AA was intragastric injected subsequently for seven days. The modified neurological severity scores (mNSS), open field test and Y-maze test were applied to detect neurological function. Magnetic resonance spectroscopy (MRS) was used to detect relevant neu- rosubstance metabolism in cortex of mice. Transmission electron microscope (TEM) was employed to observe the ultrastructure of BBB in cortex. Western blot and immunohistochemistry were used to detect the MMP-9 level in cortex. The binding possibility of A A and MMP-9 was determined by molecular docking. Results Compared with Sham group, mice in GCI/R group have an increased mNSS score but decreased at total distance and center distance to total distance ratio in open field test as well as alternation rate in Y-maze test (P<0.01). While mice in GCI/R + AA group have a decreased mNSS score but increased at total distance and center distance to total distance ratio in open field test as well as alternation rate in Y-maze test (P<0.01) compared with GCI/R group. MRS results found that in cortex of GCI/R group mice, the level of GABA and NAA significantly decreased while the Cho, mI and Tau level increased (P<0.01). Whereas in GCI/R + AA group mice, the GABA and NAA level increased and the Cho, ml and Tau decreased significantly (P<0.01). By TEM we observed that the basilemma of cerebral microvessels collapsed, the lumen narrowed, the endothelial cells were active and plasma membranes ruffled, gaps between cells were enlarged and tight junctions were damaged and the end feet of astrocytes were swollen in GCI/R group mice. While in GCI/R + AA group mice, the lumen was filled, plasma membranes of endothelial cells were smooth, tight junctions were complete and end feet of astrocytes were in normal condition. Western blot and immunohistochemistry both found that the MMP-9 level increased in GCI/R group mice (P < 0.01) and decreased in GCI/R + AA group mice (P < 0.05). Molecular docking proved the binding between aliso A and MMP9 through TYR-50 and ARG-106, and the binding energy was calculated as -6.24 kcal · mol

Observation group MMSE score when T1, T2, T3, T4 sleep quality score were higher than control group (P<0.05). Conclusion Midazolam combined with propofol was safe and had good postoperative recovery in patients undergoing laparoscopic cholecystectomy.
ABSTRACT
Age-related macular degeneration(ARMD)is one of the leading causes of irreversible visual impairment worldwide, and the number of patients is increasing with the aging of the population, with dry ARMD accounting for about 90% of cases. Effective treatments for dry ARMD are currently lacking, making it a prominent area of research. Pharmacotherapy, targeting pathogenic factors such as oxidative damage, inflammation, and vascular issues contributing to ARMD, is one of the main treatments and some drugs have been shown to slow the progression of ARMD. This article reviews drug treatments for dry ARMD, including antioxidant drugs, complement biological agents, non-steroidal anti-inflammatory drugs and immunosuppressants, vasodilators, neurotrophic drugs, as well as traditional Chinese medicine. It summarizes their mechanisms and recent clinical research to contribute valuable insights for the treatment of dry ARMD and the development of novel therapeutic agents.
ABSTRACT
AIM:To evaluate the changes in corneal biomechanics of patients with moderate refractive error after receiving small-incision lenticule extraction(SMILE)and femtosecond laser-assisted laser in situ keratomileusis(FS-LASIK)using the corneal visualization Scheimpflug technology(Corvis ST).METHODS:Prospective cohort study. A total of 65 moderate myopia patients(65 eyes)who were scheduled to undergo refractive surgery at the Ophthalmic Refractive Surgery Center of the Ningxia Eye Hospital from November 2020 to November 2021 were included in the study, and there were 30 eyes in the SMILE group and 35 eyes in the FS-LASIK group. The changes in corneal biomechanical parameters, including integrated radius(IR), inverse concave radius(ICR), deformation amplitude ratio 2mm(DAR2), stiffness parameter at first applanation(SP-A1), ambrosio relational thickness(ARTh)and the central curvature radius at highest concavity(HC-Radius)were observed by Corvis ST between both groups preoperatively and 1 and 3mo postoperatively.RESULTS: There were no statistical significance in biomechanical parameters between two groups of patients 1 and 3mo postoperatively(P&#x003E;0.05). IR, ICR and DAR2 of each groups of patients 1 and 3mo postoperatively were significantly increased than those preoperatively, and SP-A1, ARTh and HC-Radius were significantly decreased than those preoperatively(all P&#x003C;0.05). The biomechanical parameters at 1mo and 3mo postoperatively showed no statistical significance(P&#x003E;0.05). In addition, a positive correlation was found between central corneal thickness(CCT)and ARTh and SP-A1 of the two groups of patients at 3mo postoperatively(FS-LASIK group: r=0.727, 0.819, SMLIE group: r=0.683, 0.434, all P&#x003C;0.05), while a negative correlation was found between CCT and IR and ICR at 3mo postoperatively.(FS-LASIK group: r=-0.697, -0.622, SMLIE group: r=-0.447, -0.491, all P&#x003C;0.05).CONCLUSION:For patients with moderate myopia, both SMILE and FS-LASIK can reduce corneal biomechanical stability. Both surgeries showed no significant differences in the effect on biomechanical, and the biomechanical has been stabilized at 1mo postoperatively. A correlation was found between postoperative CCT and ARTh, SP-A1, IR and ICR.
ABSTRACT
Objective:To investigate the relationship between carotid atherosclerosis(CAS)and subclinical left ventricular(LV)dysfunction in type 2 diabetes mellitus patients with preserved LV ejection fraction(LVEF).Methods:A total of 120 patients with type 2 diabetes mellitus who had LVEF≥50% were selected in the Department of Endocrinology, the First Affiliated Hospital of Air Force Medical University from June 2021 to October 2021. The global longitudinal strain(GLS)was obtained by two-dimensional speckle tracking echocardiography(STE)to assess subclinical LV systolic function. The mitral ratio of peak early to late diastolic filling velocity(E/A), and mitral velocity to early diastolic velocity of the mitral annulus(E/E′)ratio were obtained by pulsed tissue Doppler echocardiography to assess LV diastolic function. Acrroding to bilateral carotid ultrasound examination, the subjects were divided into normal carotid arteries group( n=46) and CAS group( n=74). Demographics and biochemical parameters were compared between two groups. Binary logistic regression and Pearson correlation analysis were used to evaluate the relationship between CAS and subclinical LV dysfunction. Results:The CAS group had a higher proportion of men, older age, and a longer duration of diabetes than the normal carotid arteries group(all P<0.05). There was no difference in LVEF and GLS between the two groups [normal carotid arteries group vs CAS group, LVEF: (60.72±4.73)% vs(60.07±4.28)%; GLS: (18.24±3.72)% vs(17.81±3.47)%, respectively; both P>0.05]. However, compared with normal carotid arteries group, E/A ratio was decreased and E/E′ ratio was significantly increased in CAS group(both P<0.01). Pearson correlation analysis showed that GLS was not correlated with carotid plaque thickness and carotid intima-media thickness(CIMT; both P>0.05). By contrast, E/E′ ratio was positively correlated with carotid plaque thickness and CIMT(both P<0.05). Binary logistic regression analysis showed that GLS and E/E′ ratio were not associated with CAS( both P>0.05). However, decreased E/A ratio was significantly associated with the existence of CAS( OR=0.09, 95% CI 0.01-0.67, P=0.018). Conclusions:In type 2 diabetes mellitus patients without overt heart failure and with preserved LVEF, the occurrence of CAS is not associated with subclinical LV systolic impairment assessed by GLS, but is significantly associated with LV diastolic dysfunction, and is independent of traditional cardiovascular risk factors.

ABSTRACT
Objective:To investigate the effects of over-expression of E2F transcription factor 1 (E2F1) on proliferation, invasion, apoptosis and radiosensitivity of glioma cell U251.Methods:Real-time quantitative PCR (qRT-PCR) were used to detect the differential expression of E2F1 mRNA in glioma cells LN18, SW1088, U251 and normal brain glial cells. The stable over-expression of E2F1 plasmid was constructed and transfected into U251 cells. qRT-PCR and Western blot test were used to detect the expression of E2F1, pituitary tumor transforming gene 1(PTTG1), C-Myc, B-cell lymphoma-2 (Bcl-2), Bcl2-associated X (Bax) mRNA and protein expression in the control group and E2F1 over-expression group.U251 cells were divided into control group(no X-ray irradiation), irradiation group(6 Gy dose of X-ray), and irradiation + E2F1 over-expression group(transfected with E2F1 first, then irradiated by 6 Gy of X-ray). Cell proliferation ability was detected by cell counting Kit-8(CCK-8) cell viability detection reagent, and cell invasion and migration ability were detected by Transwell chamber. Apoptosis and cell cycle were detected by flow cytometry.GraphPad Prism 8.0 was used for data analysis.The statistical methods were one-way ANOVA and independent sample t-test. Results:qRT-PCR showed that there was statistical difference in the mRNA levels of E2F1( F=201.92, P<0.05) in different cell lines.The expression levels of E2F1 mRNA in LN18(4.04±0.29), SW1088(3.19±0.16)and U251(4.66±0.20) cells were higher than those in HEB(1.02±0.07)cells ( q=27.00, 19.40, 32.52, all P<0.05). After successfully constructing U251 cells with stable over-expression of E2F1 plasmid, qRT-PCR and Western blot detection results showed that: the mRNA and protein levels of E2F1, PTTG1, C-Myc and Bcl-2 in E2F1 over-expression group were higher than those in control group ( t=77.16, 57.88, 4.63, 51.13, 7.50, 70.85, 8.38, 48.81, all P<0.05). Bax mRNA(0.20±0.01) and protein(0.66±0.01) levels were lower than those in control group((1.00±0.02), (0.94±0.01)), and the differences were statistically significant ( t=1.74, 54.65, both P<0.05). After X-ray irradiation (6 Gy), CCK8 detection results showed: the proliferation ability of the three groups at 24, 48, 72 and 96 h were significantly different ( F=95.41, 187.53, 1 158.49, 7 883.78, all P<0.05). The proliferation capacity of the irradiation group were lower than those of the control group at 24, 48, 72 and 96 h ( q=19.51, 27.20, 66.60, 174.9, all P<0.05). The proliferation capacity of irradiation + E2F1 over-expression group at 24, 48, 72 and 96 h were higher than those of irradiation group ( q=10.63, 10.81, 21.11, 60.90, all P<0.05). Transwell assay results showed that there were significant differences in cell invasion and migration ability among the three groups ( F=315.38, 681.10, both P<0.05). The invasion and migration ability of cells in the irradiation group were lower than those in the control group ( q=35.09, 12.76, both P<0.05), and the invasion and migration ability of cells in the irradiation + E2F1 over-expression group were higher than those in the irradiation group ( q=52.06, 22.81, both P<0.05). Flow cytometry showed that there were significant differences in apoptosis rate and percentage of cells in each cycle among the three groups ( F=667.63, 3 213.30, 3 011.26, 861.98, all P<0.05). The percentage of the apoptosis rate, S phase and G2 phase cells in the irradiation group were higher than those in the control group ( q=51.10, 89.39, 51.82, all P<0.05), while the percentage of G1 phase cells in the irradiation group was lower than that in the control group ( q=141.2, P<0.05). The apoptosis rate and percentage of S phase and G2 phase cells in the irradiation + E2F1 over-expression group were lower than those in the irradiation group ( q=18.87, 41.42, 29.31, all P<0.05), while the number of G1 phase cells in the irradiation + E2F1 over-expression group was lower than that in the irradiation group ( q=70.73, P<0.05). Conclusion:Over-expression of E2F1 can reduce the radiosensitivity of glioma U251 cells by regulating the expression of mRNA and protein of genes related to cell cycle and apoptosis, and E2F1 may be involved in the radioresistance of glioma cells.
ABSTRACT
Objective:To analyze the clinical characteristics of pulmonary tuberculosis (PTB) in patients with prediabetes mellitus (PreDM) and improve the understanding and diagnosis of pulmonary tuberculosis complicated by prediabetes mellitus (PreDM-PTB).Methods:The clinical data of 109 inpatients with PTB who underwent glycated hemoglobin A1c (HbA1c) examination admitted to Beijing Chest Hospital, Capital Medical University from January 2015 to January 2016 were retrospectively analyzed. These patients were divided into the PreDM-PTB group ( n = 45) and the non-PreDM-PTB group (N-PreDMPTB group, n = 64) according to HbA1c test results. Patient demographic data, clinical features, imaging data, bacteriological results, and other laboratory results were collected from all patients. Results:The mean age and body mass index (BMI) were higher in the PreDM-PTB group than the N-PreDMPTB group. The proportion of patients having a smoking history was higher in the PreDM-PTB group than the N-PreDMPTB group (46.7% vs. 25.0%). The proportions of patients who had a cough (88.9%), fever (55.6%), anorexia (17.8%), chest tightness (31.1%), shortness of breath (28.9%), weight loss (40.0%), and pleural effusion (22.2%) were higher in the PreDM-PTB group than the N-PreDMPTB group. Patients with PreDM-PTB were more prone to develop anemia (55.6%), hypoproteinemia (55.6%), and increased low-density lipoprotein (26.7%) compared with patients with N-PreDMPTB. The levels of D-Dimer (93.2%), C-reactive protein (86.7%), and erythrocyte sedimentation rate (79.1%) were increased in the PreDM-PTB group compared with the N-PreDMPTB group. Sputum smear results showed that the positivity of mycobacterium tuberculosis was higher in the PreDM-PTB group (74.4%) compared with the N-PreDMPTB group. There was no significant difference in drug resistance between the two groups ( P > 0.05). The positivity of blood tuberculosis antibody and blood T-cell spot test for tuberculosis infection were 60.9% and 84.6% respectively in the PreDM-PTB group and they were 50.9% and 95.2% respectively in the N-PreDMPTB group. There were no significant differences in these two indices between the two groups ( P = 0.321, 0.066). Conclusion:Patients with Pre-DMPTB have different clinical manifestations and auxiliary examination characteristics compared with patients with N-PreDMPTB patients, which should be paid more attention to by clinicians. Early intervention should be actively adopted to prevent diabetes development from pre-DM.
ABSTRACT
Objective:To investigate the relationship between resilience, perceived social support, and adaptability in military freshmen.Methods:A total of 195 freshmen were randomly selected from a military medical university. The Chinese version of Connor-Davidson Resilience Scale (CD-RISC), the Perceived Social Support Scale (PSSS), and a self-test questionnaire of college students' psychological adaptability were used to investigate their resilience, perceived social support, and adaptability. SPSS 26.0 was used to perform an independent samples t-test and a Pearson correlation analysis to analyze the differences in these scores between freshmen with different demographic characteristics and the correlation between these scores. By using the PROCESS plug-in, a structural equation model was used to analyze the mediating effect of resilience on the relationship between social support and psychological adaptation, which was further tested using the Bootstrap method. Results:The independent samples t-test showed that females had a significantly higher score of other support than males ( t = -2.05, P = 0.041), and student leaders had significantly higher scores of family support and other support, total score of social support, and score in psychological adaptability than other students (all P<0.05). The correlation analysis showed that there were significant positive correlations between the scores of PSSS and its each item, CD-RISC, and self-test of college students' psychological adaptability (all P<0.05). The structural equation model showed that resilience partially mediated the relationship between social support and psychological adaptation, and the Bootstrap method revealed a significant indirect effect (95%CI: 0.102-0.253). Conclusion:Resilience plays a partial mediating role between perceived social support and adaptability in military freshmen. They should be guided to correctly perceive external support and develop strong resilience.
ABSTRACT
Objective:To assess the severity of hypoxic-ischemic brain damage (HIBD) in neonatal rats and predict the occurrence of subsequent neurobehavioral abnormalities after brain injury by scoring and magnetic resonance imaging (MRI).Methods:7-day-old of 60 Sprague-Dawley (SD) rats were randomly divided into control group (14 rats), sham operation group (14 rats) and HIBD model group (32 rats). HIBD model was established by right common carotid artery dissection with Rice-Vannucci method and hypoxia. Within 24 h after modeling, the rats in the model group were evaluated by general condition score and Longa score, and the surviving rats with moderate and severe HIBD were selected for the experiment. 24 h after modeling, 5 rats of the model group were randomly selected for 2,3,5-triphenyltetrazole chloride staining to verify cerebral infarction. 1 week after modeling, 6 rats from each group were randomly selected for hematoxylin-eosin staining to observe HIBD brain injury. 4 weeks after modeling, 4 rats were randomly selected from the control group and the sham operation group, and 8 rats from the remaining model group were used to evaluate the volume of brain damage by MRI. 5-6 weeks after modeling, the remaining 8 rats from each group were subjected to the Cylinder test, and at 13 weeks, they underwent the Morris water maze test to evaluate their neurobehavior.Results:In HIBD model group, 19 rats with moderate to severe HIBD were selected from 32 rats. 24 h after modeling, cerebral infarction was verified in all rats, indicating moderate to severe HIBD. Brain tissue pathology observed 1 week after modeling revealed predominantly gray matter brain damage. MRI showed that 7 out of 8 rats had moderate to severe HIBD. Compared to the control and sham operation groups, the model group exhibited a significant decrease in the usage rate of the left forelimb in the Cylinder test at 5-6 weeks after modeling ( P<0.05), and the latency period in Morris water maze test was significantly prolonged at 13 weeks after modeling ( P<0.05), and the times of crossing platform quadrant were significantly reduced ( P<0.05). There was no significant difference in the right brain injury volume between 24 h and 4 weeks model group ( P>0.05). The brain injury volume in model group was negatively correlated with the usage rate of left forelimb in cylinder test at 5-6 weeks and the times of crossing platform quadrant in Morris water maze test at 13 weeks ( P<0.05), and positively correlated with latency period in Morris water maze test at 13 weeks ( P<0.05). Conclusions:Within 24 h of HIBD modeling, the severity of brain injury can be preliminarily predicted by general condition score and Longa score. 4 weeks after modeling, in the chronic phase of brain injury, MRI was proved to be an excellent predictor for mid-term and long-term neurobehavioral abnormalities in HIBD rats.
ABSTRACT
Objective:To investigate the application value of cystic plate approach (CPA) for extrahepatic right hepatic pedicle dissection in minimally invasive anatomical hepatectomy (MIALR).Methods:The retrospective cohort study was conducted. The clinicopathological data of 42 patients with primary liver cancer who underwent laparoscopic right hemi-hepatectomy in Nanfang Hospital of Southern Medical University from August 2020 to August 2022 were collected. There were 36 males and 6 females, aged (55±13)years. Of the 42 patients, 25 cases undergoing CPA for extrahepatic right hepatic pedicle dissection were divided into the CPA group, and 17 cases undergoing traditional approach for extrahepatic right hepatic pedicle dissection were divided into the traditional approach group. Observation indicators: (1) surgical situations; (2) postoperative situations. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( IQR), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the non‐parameter rank sum test. Results:(1) Surgical situations. All patients in the two groups underwent laparos-copic right hemi-hepatectomy successfully, with the surgical margin as negative. The operation time, volume of intraoperative blood loss, time of dissection of the targeted hepatic pedicle, cases under-going dissection of the trunk of right anterior hepatic pedicle and its operation time, cases under-going dissection of the trunk of right posterior hepatic pedicle and its operation time, cases with hepatic pedicle injury, cases with hepatic tissue injury, cases with dissection space as large and small were 150.00(130.00)minutes, 100.00(100.00)mL, 472.00(201.00)seconds, 10 and 366.00(94.75)seconds, 9 and 564.00(138.50)seconds, 2, 2, 25, 0 in patients of the CPA group, versus 140.00(113.00)minutes, 100.00(125.00)mL, 670.00(107.00)seconds, 8 and 663.00(136.00)seconds, 7 and 783.00(189.00)seconds, 8, 5, 2, 19 in patients of the traditional approach group. There were significant differences in the time of dissection of the targeted hepatic pedicle, time of dissection of the trunk of right anterior hepatic pedicle, time of dissection of the trunk of right posterior hepatic pedicle, hepatic pedicle injury, dissection space between the two groups ( Z=-4.809, -3.254, -3.188, χ2=6.493, 34.314, P<0.05) and there was no significant difference in the operation time, volume of intraoperative blood loss, dissection of the trunk of right anterior hepatic pedicle, dissection of the trunk of right posterior hepatic pedicle, hepatic tissue injury between the two groups ( Z=-0.282, -0.412, χ2=0.095, 0.002, 1.976, P>0.05). (2) Postoperative situations. There was no patient under-going postoperative hemorrhage in both of the two groups. The alanine transaminase (ALT), aspartate transaminase (AST), total bilirubin (TBil) and prothrombin time (PT) at postoperative day 3, cases with postoperative biliary fistula, pathological type of tumor (hepatocellular carcinoma, intrahepatic cholangiocarcinoma) were 68.00(48.50)U/L, 52.00(35.50)U/L, 28.30(12.35)mmol/L, 12.40(2.40)seconds, 2, 21, 4 in patients of the CPA group. The above indicators were 58.00(25.00)U/L, 41.00(19.50)U/L, 26.80(14.25)mmol/L, 12.50(2.95)seconds, 5, 15, 2 in patients of the traditional approach group. There was no significant difference in the ALT, AST, TBil, PT at postoperative day 3, postoperative biliary fistula between the two groups ( Z=-1.218, -1.488, -0.205, -0.320, χ2=1.976, P>0.05), and there was no significant difference in the pathological type of tumor between the two groups ( P>0.05). Conclusion:Application of CPA for extrahepatic right hepatic pedicle dissection in MIALR is safe and feasible.

Conclusion:Application of CPA for extrahepatic right hepatic pedicle dissection in MIALR is safe and feasible.
ABSTRACT
Objective:To investigate the effect of kaempferol on proliferation, migration, and invasion of cervical cancer SiHa cells by regulating circFBXW7.Methods:SiHa cells were treated with kaempferol at low, medium, and high doses (15, 30, and 60 μmol/L) for 24 h. Untreated SiHa cells were used as the control group. CCK-8 was used to detect the effect of kaempferol on the proliferation of SiHa cells. Transwell was used to detect the effect of kaempferol on the migration and invasion of SiHa cells. Real-time fluorescence quantitative polymerase chain reaction was used to detect the expression of circFBXW7 in SiHa cells. pcDNA and pcDNA-circFBXW7 were transfected into SiHa cells, respectively, and si-NC and si-circFBXW7 were transfected into SiHa cells after adding 60 μmol/L kaempferol treatment for 24 h. The effects of circFBXW7 and its knockdown, circFBXW7, on the proliferation, migration, and invasion of SiHa cells were investigated, and the effects of E-cadherin and N-cadherin protein expression levels were detected by Western Blot. Results:Compared with the control group, the cell value-added, migration, and invasion abilities of the low, medium, and high dose groups were decreased (all P < 0.05) and were dose-related, and the expression of circFBXW7 was increased ( P < 0.05). After transfection with pcDNA-circFBXW7, the expression of circFBXW7 increased ( P < 0.05), while promoting the proliferation, cell migration, and invasion of kaempferol on SiHa cells (all P < 0.05). After transfection with si-circFBXW7, the expression of circFBXW7 decreased ( P < 0.05), while inhibiting the proliferation, cell migration, and invasion of kaempferol on SiHa cells (all P < 0.05). That indicated that the transfection of si-circFBXW7 could attenuate the inhibitory effects of kaempferol on the above oncogenic phenotypes of SiHa cells. Compared with the control group, E-cadherin expression was upregulated, and N-cadherin expression was downregulated in the low, medium, and high dose groups (all P < 0.05) in a dose-related manner. After transfection of pcDNA-circFBXW7 with SiHa cells, the expression of E-cadherin was increased, and the expression of N-cadherin was decreased (all P < 0.05). After transfection of si-circFBXW7 with SiHa cells, the expression of E-cadherin decreased, and the expression of N-cadherin increased (all P < 0.05). Conclusions:Kaempferol can reduce the proliferation, migration, and invasion abilities of SiHa cells by promoting circFBXW7 expression.
ABSTRACT
Bibliometric and scientific knowledge graph methods were used to analyze the research status and hot spots of acupuncture-moxibustion in treatment of myofascial pain syndrome (MPS) and explore its development trend. The articles of both Chinese and English versions relevant to MPS treated by acupuncture-moxibustion were searched in CNKI, VIP, Wanfang, SinoMed and WOS from the database inception to March 20, 2023. Using Excel2016, CiteSpace6.2.R2 and VOSviewer1.6.18, the visual analysis was conducted by means of the cooperative network, keyword co-occurrence, keyword timeline, keyword emergence, etc. From Chinese databases and WOS database, 910 Chinese articles and 300 English articles were included, respectively. The annual publication volume showed an overall rising trend. Literature output of English articles was concentrated in Spain, China, and the United States, of which, there was less cross-regional cooperation. In the keyword analysis, regarding acupuncture-moxibustion therapy, Chinese articles focused on "acupuncture", "electroacupuncture" and "acupotomy"; while, "dry needling" and "injection" were dominated for English one. Clinical study was the current hot spot in Chinese databases, in comparison, the randomized controlled double-blind clinical trial was predominant in WOS. Both Chinese and English articles were limited in the report of mechanism research. The cooperation among research teams should be strengthened to conduct comparative research, dose-effect research and effect mechanism research with different methods of acupuncture-moxibustion involved so that the evidences can be provided for deeper exploration.

【Objective】 To investigate the predictive factors of clinical T1 (cT1) stage renal cell carcinoma (RCC) escalation to T3a (pT3a), hoping to identify high-risk patients with occult pT3a features. 【Methods】 A total of 666 patients with cT1 RCC who underwent radical or partial nephrectomy were involved and divided into upstaging group and non-upstaging group. The independent predictive factors of cT1 to pT3a stage were determined with univariate and multivariate logistic regression analyses. A model was established. The area under the receiver operator characteristic (ROC) curve (AUC) and calibration plot were used to assess the predictive model’s discrimination and calibration. 【Results】 The upgrading rate was 11.4% (n=76). The RENAL score, neutrophil-to-lymphocyte ratio (NLR), prognosis nutrition index (PNI) and Cystatin C (Cys C) were correlated to pT3a upgrading. Our model exhibited good discrimination (AUC=0.726, 95%CI:0.662-0.791) and decent calibration. In the internal validation, the high C-index value of 0.717 was still attainable. 【Conclusions】 RENAL score, NLR, PNI, and Cys C can be used to predict the risk of postoperative pT3a stage escalation in patients with cT1 stage renal cancer. Urologists can complete risk stratification and treatment based on these indicators.
ABSTRACT
Objective To investigate the spatial distribution characteristics of the prevalence of advanced schistosomiasis and seroprevalence of anti-Schistosoma antibody, and to examine the correlation between the prevalence of advanced schistosomiasis and seroprevalence of anti-Schistosoma antibody in Hunan Province in 2020, so as to provide insights into advanced schistosomiais control in the province. Methods The epidemiological data of schistosomiasis in Hunan Province in 2020 were collected, including number of permanent residents in survey villages, number of advanced schistosomiasis patients, number of residents receiving serological tests and number of residents seropositive for anti-Schistosoma antibody, and the prevalence advanced schistosomiasis and seroprevalence of anti-Schistosoma antibody were descriptively analyzed. Village-based spatial distribution characteristics of prevalence advanced schistosomiasis and seroprevalence of anti-Schistosoma antibody were identified in Hunan Province in 2020, and the correlation between the revalence advanced schistosomiasis and seroprevalence of anti-Schistosoma antibody was examined using Spearman correlation analysis. Results The prevalence of advanced schistosomiasis was 0 to 2.72% and the seroprevalence of anti-Schistosoma antibody was 0 to 20.25% in 1 153 schistosomiasis-endemic villages in Hunan Province in 2020. Spatial clusters were identified in both the prevalence of advanced schistosomiasis (global Moran’s I = 0.416, P < 0.01) and the seroprevalence of anti-Schistosoma antibody (global Moran’s I = 0.711, P < 0.01) in Hunan Province. Local spatial autocorrelation analysis identified 98 schistosomiasis-endemic villages with high-high clusters of the prevalence of advanced schistosomiasis, 134 endemic villages with high-high clusters of the seroprevalence of anti-Schistosoma antibody and 36 endemic villages with high-high clusters of both the prevalence of advanced schistosomiasis and seroprevalence of anti-Schistosoma antibody in Hunan Province. In addition, spearman correlation analysis showed a positive correlation between the prevalence of advanced schistosomiasis and seroprevalence of anti-Schistosoma antibody (rs = 0.235, P < 0.05). Conclusions There were spatial clusters of the prevalence of advanced schistosomiasis and seroprevalence of anti-Schistosoma antibody in Hunan Province in 2020, which were predominantly located in areas neighboring the Dongting Lake. These clusters should be given a high priority in the schistosomiasis control programs.
ABSTRACT
@#The UPLC fingerprint of colistimethate sodium was established for the study of quality consistency.The chromatographic column was Acquity UPLC? Peptide CSH C18 (2.1 mm × 150 mm, 1.7 μm).The mobile phase A was phosphate buffer-acetonitrile (19∶1), and the mobile phase B was phosphate buffer-acetonitrile (1∶1).The mobile phase was in gradient elution at a flow rate of 0.3 mL/min.The column temperature was set at 30 °C and the detection wavelength was 210 nm.The similarity of the fingerprints was analyzed with the Similarity Evaluation System for Chromatographic Fingerprint of Tradition Chinese Medicine (Version 2012) in combination with content determination of multiple index components to evaluate the quality consistency of imported and domestic bulk drugs.The result showed that both the original and generic bulk drugs met the specified limit requirements in the European Pharmacopoeia standards, and that their UPLC fingerprints were highly similar, indicating that the quality of the two substances was consistent.Establishing a fingerprint for similarity evaluation and combining it with the results of indicator component content determination as a comprehensive evaluation method for the study of drug quality consistency of complex components has the characteristics of fast, accurate, and comprehensive, which is helpful for drug quality evaluation and provides ideas for the evaluation of antibiotic quality consistency of complex components.
