Objective To analyze the epidemiological characteristics of mumps in Guangxi from 2012 to 2024, and to provide a scientific basis for formulating prevention and control strategies. Methods Descriptive epidemiological methods were used to analyze the incidence data of mumps in Guangxi from 2012 to 2024. Results A total of 159 873 mumps cases were reported from 2012 to 2024 in Guangxi, with an average annual reported incidence of 25.41/100 000, and no death. Mumps occurred every month, with the peak incidence mainly concentrated in April to July and October to January of the next year. There were 96,118 male cases (29.43 /100 000), and 63 755 female cases (21.07 /100 000). The male to female ratio was 1.40:1, and the difference between male and female was significant (χ²=4 321.276，P＜0.05). The annual incidence of mumps showed a certain periodic change, with the incidence peak and trough alternating every 4 - 5 years. The majority of patients were under 15 years old, accounting for 85.32% of the total number of cases. The patients mainly included students, preschool children and scattered children. The highest average incidence was in Nanning City with 40 231 cases (42.08/100 000), and the lowest was in Qinzhou City with 3 466 cases (8.16/100 000). From 2012 to 2024, a total of 210 mumps outbreaks with 4 483 cases were reported in Guangxi. Conclusion The incidence of mumps in Guangxi from 2012 to 2024 shows a periodic change and obvious seasonality. People under 15 years old are the key group at risk of mumps. The prevention and control of the epidemic of mumps in schools and kindergartens should be strengthened. It is suggested to carry out long-term monitoring of mumps as well as immune effect research, and continue to maintain a high vaccination rate of 2 doses of mumps-containing vaccines.

Objective To explore the short-term outcome and safety of 577 nm subthreshold micropulse laser(SML)in the treatment of central serous chorioretinopathy(CSC).Methods The clinical data of 22 patients(24 eyes)with CSC who were admitted to First Affiliated Hospital of Army Medical University from April 2023 to April 2024 were retrospectively analyzed.The 12 eyes had acute CSC,the 12 eyes had chronic CSC,and all of them were treated with SML.The changes of best-corrected visual acuity(BCVA),central macular thickness(CMT),subfoveal choroidal thickness(SFCT),subretinal fluid height(SRFH),and central macular sensitivity(CMS)before treatment and 1 month after treatment were analyzed.The absorption of subretinal fluid 1 month after treatment and related complications were observed.Results Compared with those before treatment,the CMT,SFCT,and SRFH 1 month after treatment significantly declined(P<0.05).The LogMAR BCVA and CMS 1 month after treatment were significantly improved compared with those before treatment(P<0.05).The CMS(r=-0.555,P=0.006)and LogMAR BCVA(r=0.439,P=0.032)before treatment were significantly correlated with SRFH before treatment.The change of SRFH was significantly correlated with CMT before treatment(r=0.616,P=0.001),but without correlation with SFCT before treatment(r=0.168,P=0.431).One month after treatment,11 eyes had complete absorption of subretinal fluid,12 eyes had varying degrees of absorption,and 1 eye had an increase in SRFH.No related adverse reactions were observed.Conclusion The 577 nm SML has a good therapeutic effect on CSC,which can significantly improve the macular structure and central visual function,with good safety.

Objective To investigate the effect of exosomal miR-146a-5p expression on gray matter volume in patients with major depressive disorder(MDD).Methods A total of 113 MDD patients(MDD group)and 107 healthy controls(HC)(HC group)were selected.Peripheral blood was collected and exosomes were isolated to quantify miR-146a-5p expression.Brain high-resolution T1 WI images of MDD and HC were obtained via MR,and gray matter volume was computed via SPM12 software.The interaction effect of"Depression×miR-146a-5p expression"on gray matter volume was analyzed using SPM's Flexible factorial design,and the between-group difference was assessed by extracting the mean value,thus to analyze whether MDD-related gray matter volume abnormalities were dependent on miR-146a-5p expression.Results Exosomal miR-146a-5p expression was significantly elevated in MDD group compared to HC group.Voxel-based factorial analysis revealed a relationship between high miR-146a-5p expression in MDD group and reduced gray matter volume in the anterior and posterior cingulate cortices(independent voxel threshold P＜0.001,AlphaSim corrected),and a significantly reduced gray matter volume as compared with HC group was detected in the two regions.Conclusion The exosomal miR-146a-5p is overexpressed in patients with MDD and may be associated with specific cortical atrophy in patients with MDD.

Objective:To design a motor impairment rehabilitation monitoring aid for the assessment of motor impairment in patients who do not have or have difficulty walking independently.Methods:An assistive device vehicle was designed, equipped with an accelerometer and a six-dimensional force sensor. The normal walking (NW) group and abnormal walking group were set up, in which the abnormal walking group included moderate abnormal walking (MA) group, moderate abnormal walking with the aid of the assistive vehicle (MA-V) group, severe abnormal walking (SA) group, and severe abnormal walking with the aid of the assistive vehicle (SA-V) group. In the MA-V group, the range of knee movement was adjusted from 0 to 30°, and in the SA group, the knee joint was completely unbending. The gait cycles, peak and mean acceleration values of the right and left legs were evaluated by accelerometers, and changes in the upper limb forces were assessed by six-dimensional force transducers.Results:For the moderate impairment group, the difference in gait cycle between the MA and MA-V groups was not statistically significant ( P>0.05), and the gait cycle in the MA-V group was slightly greater than that in the MA group. For the severe injury group, the gait cycle of the SA-V group was lower than that of the SA group, and the difference was statistically significant ( P<0.01). For all abnormal groups, the mean and peak acceleration of the left leg were greater than that of the right leg, and the difference between the peak acceleration of the left leg and that of the right leg was statistically significant ( P<0.05). In the abnormal walking pattern, the mean (absolute) value of the left hand force was greater than that of the right hand, especially in the Z-axis. The standard deviations of the combined forces on the left side for the NW, MA-V, and SA-V groups were 2.759, 8.297, and 13.118 N, respectively. The SA-V group had the highest dispersion in the force scatter plot, while the NW group had a better concentration. Conclusions:An assistive vehicle equipped with an accelerometer and a six-dimensional force sensor was designed to help physicians in the assessment and rehabilitation of motor disorders.

Objective: To explore the efficacy of chemotherapy re-challenge in the third-line setting for patients with metastatic colorectal cancer (mCRC) in the real world. Methods: The clinicopathological data, treatment information, recent treatment efficacy, adverse events and survival data of mCRC patients who had disease progression after treatment with oxaliplatin-based and/or irinotecan-based chemotherapy and received third-line chemotherapy re-challenge from January 2013 to December 2020 at Tianjin Medical University Cancer Institute and Hospital were retrospectively collected. Survival curves were plotted with the Kaplan-Meier method, and the Cox proportional hazard model was used to analyze the prognostic factors. Results: A total of 95 mCRC patients were included. Among them, 32 patients (33.7%) received chemotherapy alone and 63 patients (66.3%) received chemotherapy combined with targeted drugs. Eighty-three patients were treated with dual-drug chemotherapy (87.4%), including oxaliplatin re-challenge in 35 patients and irinotecan re-challenge in 48 patients. The remaining 12 patients were treated with triplet chemotherapy regimens (12.6%). Among them, as 5 patients had sequential application of oxaliplatin and irinotecan in front-line treatments, their third-line therapy re-challenged both oxaliplatin and irinotecan; 7 patients only had oxaliplatin prescription before, and these patients re-challenged oxaliplatin in the third-line treatment. The overall response rate (ORR) and disease control rate (DCR) reached 8.6% (8/93) and 61.3% (57/93), respectively. The median progression free survival (mPFS) and median overall survival (mOS) were 4.9 months and 13.0 months, respectively. The most common adverse events were leukopenia (34.7%) and neutropenia (34.7%), followed by gastrointestinal adverse reactions such as nausea (32.6%) and vomiting (31.6%). Grade 3-4 adverse events were mostly hematological toxicity. Cox multivariate analysis showed that gender (HR=1.609, 95% CI: 1.016-2.548) and the PFS of front-line treatments (HR=0.598, 95% CI: 0.378-0.947) were independent prognostic factors. Conclusion: The results suggested that it is safe and effective for mCRC patients to choose third-line chemotherapy re-challenge, especially for patients with a PFS of more than one year in front-line treatments.

Metastasis is crucial for the mortality of non-small cell lung carcinoma (NSCLC) patients. The epithelial-mesenchymal transition (EMT) plays a critical role in regulating tumor metastasis. Glioma-associated oncogene 1 (Gli1) is aberrantly active in a series of tumor tissues. However, the molecular regulatory relationships between Gli1 and NSCLC metastasis have not yet been identified. Herein, we reported Gli1 promoted NSCLC metastasis. High Gli1 expression was associated with poor survival of NSCLC patients. Ectopic expression of Gli1 in low metastatic A549 and NCI-H460 cells enhanced their migration, invasion abilities and facilitated EMT process, whereas knock-down of Gli1 in high metastatic NCI-H1299 and NCI-H1703 cells showed an opposite effect. Notably, Gli1 overexpression accelerated the lung and liver metastasis of NSCLC in the intravenously injected metastasis model. Further research showed that Gli1 positively regulated Snail expression by binding to its promoter and enhancing its protein stability, thereby facilitating the migration, invasion and EMT of NSCLC. In addition, administration of GANT-61, a Gli1 inhibitor, obviously suppressed the metastasis of NSCLC. Collectively, our study reveals that Gli1 is a critical regulator for NSCLC metastasis and suggests that targeting Gli1 is a prospective therapy strategy for metastatic NSCLC.

Eucommiae Folium(EF),a traditional Chinese medicine,has been used to treat secondary hypertension,including renal hypertension and salt-sensitive hypertension,as well as hypertension caused by thoracic aortic endothelial dysfunction,a high-fat diet,and oxidized low-density lipoprotein.The antihyperten-sive components of EF are divided into four categories:flavonoids,iridoids,lignans,and phenyl-propanoids,such as chlorogenic acid,geniposide acid and pinoresinol diglucoside.EF regulates the occurrence and development of hypertension by regulating biological processes,such as inhibiting inflammation,regulating the nitric oxide synthase pathway,reducing oxidative stress levels,regulating endothelial vasoactive factors,and lowering blood pressure.However,its molecular antihypertensive mechanisms are still unclear and require further investigation.In this review,by consulting the relevant literature on the antihypertensive effects of EF and using network pharmacology,we summarized the active ingredients and pharmacological mechanisms of EF in the treatment of hypertension to clarify how EF is associated with secondary hypertension,the related components,and underlying mechanisms.The results of the network pharmacology analysis indicated that EF treats hypertension through a multi-component,multi-target and multi-pathway mechanism.In particular,we discussed the role of EF tar-gets in the treatment of hypertension,including epithelial sodium channel,heat shock protein70,rho-associated protein kinase 1,catalase,and superoxide dismutase.The relevant signal transduction path-ways,the ras homolog family member A(RhoA)/Rho-associated protein kinase(ROCK)and nicotinamide adenine dinucleotide phosphate(NADPH)oxidase/eNOS/NO/Ca2+pathways,are also discussed.

Objective To analyze the epidemiological characteristics of hepatitis A in Guangxi from 2010 to 2020, and to provide a scientific basis for formulating effective prevention and control strategies. Methods Descriptive epidemiological method was used to analyze the incidence data of hepatitis A in Guangxi from 2010 to 2020. Results From 2010 to 2020, a total of 8,742 cases of hepatitis A were reported in Guangxi, with an average annual incidence rate of 1.66 /100,000. There were 5 298 male cases (60.60%), and 3,444 female cases (39.40%). The incidence rate decreased from 2.73/100 000 in 2010 to 1.38/100 000 in 2020. The onset seasonality was strong in 2010, but there was no obvious seasonality in other years. A total of 5 891 cases (67.39%) were aged from 25 to 64 years. Farmers accounted for 59.79% of the cases. A total of 7 hepatitis A outbreaks were reported during 2010-2020, including 273 cases，accounting for 3.12% of the total cases．The incidence rates of hepatitis A in Hezhou (3.97/100 000), Wuzhou (2.98/100 000), Hechi (2.44/100 000), Guigang (2.00/100 000) and Beihai (1.79/100 000) were relatively higher than other places. Conclusion The number of reported hepatitis A cases in Guangxi has been declining year by year, and the prevention and control measures of hepatitis A vaccine prevention are effective. The surveillance of hepatitis A should be strengthened, and prevention and control strategies should be formulated for high-risk areas and key populations.

Objective:To analyze the effects of two decomposition algorithms of dual-energy cone beam CT (DECBCT) (direct decomposition and iterative decomposition) on the image quality and material decomposition accuracy of different sizes of phantoms.Methods:Different sizes of imaging parts of patients were simulated using the combination of CatPhan604 phantoms and customized annuluses. CBCT with high energy of 140 kVp and low energy of 100 kVp were acquired using the Varian Edge CBCT system. Then the material decomposition of DECBCT images was performed using the two algorithms. The electron density (ED) and contrast-to-noise ratio (CNR) of each material in the CTP682 module were calculated. They were used to assess the decomposition accuracy and image quality of the two algorithms.Results:Based on the values in the Catphan604 manual, both algorithms have high ED accuracy. Only the ED accuracy of four materials of the smallest sized phantom showed statistical difference ( z = -4.21, 4.30, 2.87, 5.45, P < 0.05), but the average relative error was less than 1%. The CNR of the iterative decomposition algorithm was significantly higher than that of the direct decomposition, increasing by 51.8%-703.47%. The increase in the phantom size significantly reduced the accuracy of ED, and the increased amplitude of the relative error was up to a maximum of 2.52%. The large phantom size also reduced the image quality of iterative decomposition, and the decreased amplitude of CNR was up to a maximum of 39.71. Conclusions:Compared with the direct decomposition, the iterative decomposition algorithm can significantly reduce the image noise and improve the contrast without losing the accuracy of electron density in the DECBCT construction of different sizes of phantoms.
