Objective:To observe the efficacy of hypertonic dextrose injection(prolotherapy)at retrodiscal tissue in the treatment of chronic joint pain in patients with temporomandibular disorders(TMD).Methods:From June 2012 to March 2022,244 patients(aged 16 to 75 years)underwent the treatment were included and classified according to DC/TMD.The treatment started from an anesthetic in-jection of 2％lidocaine(1.5-2 mL)into the retrodiscal tissue.The patients were then instructed to perform mandibular condylar exercise for 5-10 min,prior to the therapeutic injection of 50％dextrose(1-1.5 mL)by using the same method.Assessment of TMJ pain and jaw function was performed at 2 weeks,2,6 and 12 months after injection.Results:By March 2022,221 cases completed the final sur-vey(the rate of loss of follow-up was 9.4％),the average follow-up time was(75.7±25.1)months.2 weeks after treatment,there was significant relief of joint pain,and mandibular function was significantly improved in most patients by 2 month after treatment.Of these,186 cases achieved profound pain relief and faily normal jaw function,17 cases with recurrence of joint pain and jaw dysfunction and op-ted for occlusal splint treatment due to fear of injection,16 cases claimed no obvious therapeutic effect but rejected any further tratment,2 cases subsequently accepted TMJ surgery.There was no worsening of TMD or other complication as a result of the treatment.Conclu-sion:Hypertonic dextrose injection in retrodiscal tissue attachment is straightforward,safe and effective in the treatment of chronic joint pain and TMD.

Objective:Analyzing the epidemic trends and spatio-temporal distribution characteristics of condyloma acuminatum in China from 2018 to 2023.Methods:Data of condyloma acuminatum cases and incidence rate including 31 provinces (autonomous regions and municipalities) from 2018 to 2023 were collected through the National Notifiable Infectious Disease Reporting System of China Information System for Disease Control and Prevention. Incidence trend analysis was conducted using Joinpoint 4.9.1 software, and spatial autocorrelation analysis using ArcGIS 10.5 software. Spatio-temporal scanning analysis was carried out with SaTScan 10.1.2 software.Results:The incidence rate of condyloma acuminatum declined from 7.26 per 100 000 in 2018 to 7.19 per 100 000 in 2023. The average annual percent change was -0.26%, which was no statistically significant downward trend ( t=-0.26, P=0.806). A significant positive global spatial autocorrelation was observed in the county-level incidence rate across the country, with the global Moran's I ranging from 0.55 to 0.60 (all P<0.001); the Getis-Ord General test statistic Z( G) was all >1.96, indicating a high-value clustering pattern in the reported incidence rate of condyloma acuminatum. The local spatial autocorrelation analysis detected 256, 244, 246, 284, 308, and 315 hotspots each year, which were mainly located in the provinces of Zhejiang, Fujian, Guangdong, Guizhou, Yunnan and Chongqing. Spatio-temporal scanning analyses identified 76 statistically significant spatiotemporal clusters covering 25 provinces (autonomous regions and municipalities). Conclusions:From 2018 to 2023, the reported incidence rate of condyloma acuminata in China exhibited a mild decline. The distribution of hotspot areas and spatiotemporal clusters was largely consistent, primarily in the southeastern coastal and southwestern regions.

Objective:To investigate the epidemic trends and spatiotemporal distribution characteristics of genital Chlamydia trachomatis infection in China in recent years, and to provide a reference for its precise prevention and control.Methods:Data on reported cases of genital Chlamydia trachomatis infection in China (not including Hongkong, Macau and Taiwan regions of China) were collected through the Infectious Diseases Surveillance System of Chinese Disease Prevention and Control Information System from 2018 to 2023. The trend in the incidence rate was analyzed using the Joinpoint 4.9.1 software. Global and local spatial autocorrelation analyses at the county level were conducted using the ArcGIS 10.5 software. Spatiotemporal scanning analysis was carried out with the SaTScan 10.1.2 software.Results:The reported incidence rates of genital Chlamydia trachomatis infection slightly declined from 12.66 per 100 000 in 2018 to 12.45 per 100 000 in 2023, with an average annual percent change of -1.42%, which was not statistically significant ( t = -1.14, P = 0.318). The reported incidence rates of genital Chlamydia trachomatis infection at the county level in China showed a significant positive global spatial autocorrelation, with the global Moran's indices ranging from 0.68 to 0.74 (all P < 0.001) ; the standardized statistic Z (G) values for the Getis-Ord general G were all greater than 1.96, indicating a high-value clustering pattern. Local spatial autocorrelation analysis revealed that hotspot areas were predominantly located in southern and eastern China. In the spatiotemporal scanning analysis, 38 statistically significant spatiotemporal clusters were identified, mainly distributed in southern and eastern China and consistent with the hotspot areas. Conclusions:From 2018 to 2023, the reported incidence rates of genital Chlamydia trachomatis infection showed a slight decline, and the epidemic exhibited spatiotemporal clustering characteristics in China. Targeted prevention and control measures need to be implemented in hotspot areas and spatiotemporal clusters.

Objective:To investigate the epidemiological trends and spatio-temporal distribution characteristics of syphilis in China from 2010 to 2023.Methods:Data on syphilis cases reported from 31 provinces, autonomous regions or municipalities from 2010 to 2023 were collected from the Infectious Diseases Surveillance System of Chinese Disease Prevention and Control Information System. Joinpoint 5.2.0 software was used to analyze the epidemiological trends of syphilis, ArcGIS 10.5 software was used for spatial autocorrelation analysis at the county level, and SaTScan 10.2.3 software was used for space-time scan analysis.Results:The national reported incidence rates of syphilis increased from 26.86 per 100 000 in 2010 to 37.60 per 100 000 in 2023, with an average annual percent change of 1.82% (95% CI: 0.81% - 2.89%), and the upward trend in the reported incidence rates was statistically significant ( P = 0.002). There was a positive spatial autocorrelation in the reported incidence rates of syphilis at the county level in China (Moran's Ⅰ range: 0.47 - 0.60, all P < 0.001), and all of the Getis-Ord general test statistic Z (G) values were > 1.96, indicating a high-value clustering pattern in the reported incidence rates of syphilis. The local spatial autocorrelation analysis showed that the annual number of hotspot areas ranged from 180 to 294, which were mainly located in Xinjiang, Qinghai, Guizhou, Sichuan and Yunnan. A total of 92 spatio-temporal clusters were identified by space-time scan analysis, which were mainly distributed in Zhejiang, Guangxi, Guangdong and Fujian from 2010 to 2012, in Xinjiang from 2013 to 2017, and in Sichuan, Guizhou, Chongqing, etc., from 2019 to 2023. Conclusions:From 2010 to 2023, the reported incidence rates of syphilis in China exhibited a fluctuating increase on the whole, with obvious spatio-temporal clustering characteristics. The hotspot areas were basically consistent with the spatio-temporal clusters, and were mainly distributed in the northwestern, southeastern coastal and southwestern areas. Over time, the spatio-temporal clusters gradually changed from the southeast coastal and northwestern areas to the southwestern areas.

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors, with rapid progression and a poor prognosis. More and more studies have shown that there are small open reading frames (sORFs) on the molecular sequences of a large number of non-coding RNAs (ncRNAs), which can encode conserved peptides that play an important role in controlling the occurrence and development of HCC. This article introduces the discovery, prediction, and validation methods of ncRNA-encoding polypeptides and reviews its research progress, with the aim of providing new targets and ideas for early-stage diagnosis, targeted therapy, and prognosis assessment of HCC.

Objective To observe the effects of folic acid(FA)supplementation on the expression of Flotillin-1 and β-amyloid protein(Aβ)-metabolism-related proteins in the brains of inflammation-stimulated Alzheimer's disease(AD)mice.Methods Twenty-seven 6-month-old male APP/PS1 mice were randomly divided into AD,AD+LPS,and AD+LPS+FA groups,with nine mice in each group.Nine C57BL/6J male mice born within the same month were used as the Control group.The AD+LPS+FA group was given folic-acid-supplemented feed(8 mg/kg)for 3 months of intervention,while the other three groups were fed normal feed.Lipopolysaccharide solution(LPS,250 μg/(kg·d))was injected intraperitoneally into mice in the AD+LPS and AD+LPS+FA groups 1 week before the end of the experiment,and saline was injected into the remaining two groups.The serum inflammatory factors TNF-α and IL-6 levels and brain tissue Aβ1-40 and Aβ1-42 levels of mice in each group were detected by ELISA.Flotillin-1 protein expression in brain tissue was detected using Western blot,and the co-expression of Flotillin-1 and Aβ1-42/APP/PS1/BACE1 in the cortical region of the brain was detected via immunofluorescence double-labeling.Results After ANOVA analysis,we found mice in the AD group had elevated serum TNF-α and IL-6 levels(P＜0.05),elevated levels of Aβ1-40 and Aβ1-42(P＜0.05),increased expression of Flotillin-1 protein(P＜0.05),and increased co-expression of Flotillin-1 and Aβ1-42/APP/PS1/BACE1 in the cortical brain tissue(P＜0.05)compared with the Control group.Compared with mice in the AD group,those in the AD+LPS group had further increases in serum inflammatory factors and Aβ levels in the brain(P＜0.05)and increased co-expression of Flotillin-1 and Aβ1-42/APP/BACE1 double-labeled proteins in their cortical brain tissue(P＜0.05).Compared with mice in the AD+LPS group,those in the AD+LPS+FA group had lower in vivo inflammation levels and Aβ content in the brain(P＜0.05),lower brain tissue Flotillin-1 protein expression(P＜0.05),and lower Flotillin-1 and Aβ1-42/APP/PS1/BACE1 protein co-expression in cortical brain tissue(P＜0.05).Conclusions Folic acid supplementation may reduce Flotillin-1 protein expression and Aβ deposition in the brain of AD inflammatory mice.

Objective:To evaluate the expression level of hsa-miR-422a in hypertrophic scars and to identify the target genes of hsa-miR-422a along with their biological functions using bioinformatics approaches.Methods:From June 2020 to December 2020, tissue samples of 3 hypertrophic scar and 3 normal skin were collected from patients (3 males, 3 females, aged 20-42 years) in Department of Plastic and Reconstructive Surgery, Shanghai Ninth People′s Hospital, Shanghai Jiaotong University School of Medicine. Primary fibroblasts were isolated and cultured. Real-time quantitative PCR was performed to quantify the expression of hsa-miR-422a. To construct a ceRNA network, starbase and Target Scandata bases were utilized to predict genes as well as long noncoding RNAs (lncRNAs) that may sponge hsa-miR-422a. GO and KEGG pathway enrichment analyses were conducted on the target genes of hsa-miR-422a; protein-protein interaction (PPI) networks were constructed to identify the hub genes whose functions were predicted by functional enrichment analyses. The expression of hub genes was validated through real-time quantitative PCR in hypertrophic scars.Results:The expression of hsa-miR-422a was significantly lower in the hypertrophic scar tissue samples and fibroblasts compared to that in the normal skin ( P<0.05). 133 target genes as well as 1033 lncRNAs were predicted by starBase and TargetScandata bases and used to construct an hsa-miR-422a-centered ceRNA network. PPI networks of the target genes revealed 10 hub genes, including MAPK1, GRB2, and IGF1R, which were discovered to be related to protein serine/threonine/tyrosine kinase activity, ubiquitin protein ligase binding, fibroblast growth factor receptor signaling pathway, muscle cell proliferation, and many others; besides, they may be involved in FoxO, mTOR, Toll-like receptor, Ras, MAPK, PI3K-Akt signaling pathways and signaling pathways regulating pluripotency of stem cells. Three hub genes (MAPK1, GRB2, and IGF1R) were significantly upregulated in hypertrophic scars ( P<0.05). Conclusions:hsa-miR-422a is significantly downregulated in the hypertrophic scars and may target hub genes such as MAPK1 in ceRNA networks, ultimately modulating hypertrophic scar formation.

[Objective] To construct a Nomogram model for the prediction of essential hypertension (EH) risks with the use of traditional Chinese medicine (TCM) syndrome elements principles in conjunction with cutting-edge biochemical detection technologies. [Methods] A case-control study was conducted, involving 301 patients with essential hypertension in the hypertensive group and 314 without in the control group. Comprehensive data, including the information on the four TCM diagnoses, general data, and blood biochemical indicators of participants in both groups, were collected separately for analysis. The differentiation principles of syndrome elements were used to discern the location and nature of hypertension. One-way analysis was carried out to screen for potential risk factors of the disease. Least absolute shrinkage and selection operator (LASSO) regression was used to identify factors that contribute significantly to the model, and eliminate possible collinearity problems. At last, multivariate logistic regression analysis was used to both screen and quantify independent risk factors essential for the prediction model. The “rms” package in the R Studio was used to construct the Nomogram model, creating line segments of varying lengths based on the contribution of each risk factor to aid in the prediction of risks of hypertension. For internal model validation, the Bootstrap program package was utilized to perform 1000 repetitions of sampling and generate calibration curves. [Results] The results of the multivariate logistic regression analysis revealed that the risk factors of EH included age, heart rate (HR), waist-to-hip ratio (WHR), uric acid (UA) levels, family medical history, sleep patterns (early awakening and light sleep), water intake, and psychological traits (depression and anger). Additionally, TCM syndrome elements such as phlegm, Yin deficiency, and Yang hyperactivity contributed to the risk of EH onset as well. TCM syndrome elements liver, spleen, and kidney were also considered the risk factors of EH. Next, the Nomogram model was constructed using the aforementioned 14 risk predictors, with an area under the curve (AUC) of 0.868 and a 95% confidence interval (CI) ranging from 0.840 to 0.895. The diagnostic sensitivity and specificity were found to be 80.7% and 85.0%, respectively. Internal validation confirmed the model’s robust predictive performance, with aconsistency index (C-index) of 0.879, underscoring the model’s strong predictive ability. [Conclusion] By integrating TCM syndrome elements, the Nomogram model has realized the objective, qualitative, and quantitative selection of early warning factors for developing EH, resulting in the creation of a more comprehensive and precise prediction model for EH risks.

OBJECTIVE To analyze the effects of tigecycline on coagulation function in patients with severe renal insufficiency， and to provide a reference for safe clinical drug use. METHODS Retrospective analysis was performed for the clinical data of patients with severe renal dysfunction complicated with infection receiving tigecycline admitted to nephrology department of our hospital from January 2021 to October 2022. The levels of prothrombin time （PT）， activated partial thromboplastin time （APTT）， international normalized ratio （INR）， platelet （PLT） and fibrinogen （FIB） were compared 3 days before medication， with 1-5， 6-10， 11-15 and 16-20 days after medication， 5 days after withdrawal and/or after symptomatic treatment. RESULTS Finally， 14 patients were included， and 9 patients developed coagulopathy， with an incidence of 64.29%. Compared with 3 days after medication， the levels of FIB at 6-10 and 11-15 days after medication， and PLT at 1-5 ， 6-10 and 11- 15 days after medication were decreased significantly， while the levels of PT at 1-5 and 6-10 days after medication， APTT at 1-5， 6-10 and 11-15 days after medication were significantly prolonged， and INR increased significantly at 1-5 and 6-10 days after medication （P＜0.05）. Compared with 3 days before medication， there were no statistically significant changes in FIB， PT， INR， APTT and PLT at 16-20 days after medication and 5 days after withdrawal and/or symptomatic treatment（P＞0.05）. CONCLUSIONS Patients with severe renal insufficiency should be cautious with tigecycline， which can lead to prolonged PT and APTT， increased INR， and decreased PLT and FIB. If medication time is over 14 days， dynamic monitoring of coagulation function indicators is recommended to reduce the risk of adverse reactions.
