Objective:To investigate the effect of minocycline on neuroinflammation of rats with post-traumatic stress disorder(PTSD).Methods:The rat model of PTSD was prepared by a single prolonged stress(SPS)method,and the rats were treated with minocycline(PTSD+Mino group)or normal saline(PTSD group)by gavage.The behavioral changes of rats were detected by light-dark box test.The expression of ionized calcium-binding adapter molecule 1(Iba-1)in hippocampus was detected by immunohistochemical staining.The contents of IL-1β and TNF-α in hippocampus were detected by ELISA,and the expression levels of IL-1β and TNF-α mRNA in hippocampus were detected by real-time RT-PCR(qRT-PCR).Results:After 3 days of SPS stimulation,the anxiety-like behavior of rats was obvious,the expression of Iba-1 in hippocampus was increased,and the contents of IL-1β and TNF-α in hippocampus were in-creased.Minocycline treatment significantly reduced anxiety-like behavior and decreased the expression of Iba-1 in the hippocampus of PTSD rats.Meanwhile,minocycline treatment also decreased the levels of IL-1β and TNF-α mRNA and protein in the hippocampus.Conclusion:Minocycline can improve the anxiety-like behavior of PTSD rats by inhibiting the activation of microglia.

AIM: To compare the efficacy of different dosing regimens of conbercept in the treatment of pathological myopic choroidal neovascularization(CNV).METHODS: Prospective clinical study. Totally 42 patients(42 eyes)who were diagnosed with pathological myopic CNV in our hospital from January 2019 to January 2022 were selected in the study. According to two different initial dosing regimens, the patients were divided into 1+pro re nata(PRN)group, with 20 patients(20 eyes), and 3+PRN group with 22 patients(22 eyes). The patients in the 1+PRN group were given one intravitreal injection and then given PRN, the patients in the 3+PRN group were given intravitreal injection once a month for 3 mo and then given PRN. Followed-up for 12 mo after initial treatment, the best corrected visual acuity(BCVA), central macular thickness(CMT), CNV area and injection times were compared between the two groups.RESULTS: The BCVA was improved, CMT was decreased, and CNV area was reduced at 1, 3, 6, and 12 mo after the initial treatment(P<0.01). However, there was no statistically significant difference in BCVA, CMT and CNV area between two groups(P>0.05). The average injection in the 1+PRN group was significantly less than that of the 3+PRN group [2(1, 3)times vs 3(3, 4)times, P<0.05], but the average reinjection in the 1+PRN group was more than that of the 3+PRN group [1(0, 2)times vs 0(0, 1)times, P<0.05].CONCLUSION: Two regimens were both safe and effective in the treatment of pathological myopic CNV by Conbercept, which can improve BCVA, decrease CMT, and reduce CNV area, with less total times of injection in the 1+PRN regimen, and less times of reinjection in the 3+PRN regimen.

Objective To investigate the prevalence of Echinococcus infections in small rodents around human residential areas in Yushu City, Qinghai Province in 2023, so as to provide insights into precision echinococcosis control. Methods One or two quadrats, each measuring 50 m × 50 m, were randomly assigned in Shanglaxiu Township and Longbao Township, Yushu City, Qinghai Province on June 2023, respectively, and 300 plate-type mouse traps, each measuring 12.0 cm × 6.5 cm, were assigned in each quadrat. Small rodents were captured during the period between 10 : 00 and 18 : 00 each day for 4 days. Then, all captured small rodents were identified and dissected, and liver specimens with suspected Echinococcus infections were subjected to pathological examinations. The Echinococcus cytochrome c oxidase 1 (cox1) gene was amplified using PCR assay, and the sequence of the amplified product was aligned to that was recorded in the GenBank to characterize the parasite species. In addition, a phylogenetic tree of Echinococcus was generated based on the cox1 gene sequence using the neighbor-joining method. Results A total of 236 small rodents were captured in Shanglaxiu and Longbao townships, Yushu City, including 65 Qinghai voles and 51 plateau pikas in Shanglaxiu Township, and 62 Qinghai voles and 58 plateau pikas in Longbao Township, and there was no significant difference in the constituent ratio of small rodents between the two townships (χ² = 0.294, P > 0.05). Seven plateau pikas and 12 Qinghai voles were suspected to be infected with Echinococcus by dissection, and pathological examinations showed unclear structure of hepatic lobules and disordered hepatocyte arrangement in livers of small rodents suspected of Echinococcus infections. PCR assay identified E. shiquicus DNA in 7 Qinghai voles, which were all captured from Shanglaxiu Township. Phylogenetic analysis showed that the cox1 gene sequence of Echinococcus in small rodents was highly homologous to the E. shiquicus cox1 gene sequence reported previously. Conclusion Plateau pika and Qinghai vole were predominant small rodents around human residential areas in Yushu City, Qinghai Province in 2023, and E. shiquicus infection was detected in Qinghai voles.

Objective To explore the effects of different types of drinking water on the growth and fecal flora of mice.Methods Specific pathogen-free NIH mice were randomly divided into five groups,32 mice each group,with half males and half females in each group.The group were given either purified water(control group),acidified water,alkalized water,weakly acidic water or solid water.Diet and body weight were monitored continuously for 20 days.After the experiment,animal fecal samples were collected,and the V3-V4 region was amplified with bacterial 16S rDNA universal primers.An Illumina Miseq high-throughput sequencing platform was used for high-throughput sequencing,and microbial community,α diversity and β diversity were analyzed by bioinformatics method.Results The body weight of female mice given different pH values of weakly acidic water was higher,while the weight of the other groups was lower,than that of the control group(P＞0.05).The body weight of male mice in the acidified water group was higher,while that of other groups was lower,than that of control group,but there was no statistical difference between the groups(P＞0.05).The body weights of male and female mice in the solid water group were lower than those in the control group(P＜0.05).The food and water intake of the female animals in the alkaline water group and the water intake of female animals in the solid water group were lower than those of the other groups.OTU clustering analysis showed that the data volume of the sequencing was reasonable,and the fecal flora species of NIH mice were divided into five phyla,among which Bacteroides and Firmicutes were dominant.Unclassified Pseudopurpuromonas,Lactobacillus and Alistipes were the main genera.There were differences in fecal flora abundance and diversity among the mice given the five drinking water types.α analysis showed that the acidified water group had the highest flora abundance and diversity,while the solid water group had the lowest flora diversity.β analysis showed that the fecal flora composition in the solid water group was the closest to that of the control group,followed by the alkalized water group,acidified water group and weakly acidic water group.Conclusions Through an exploration of the effects of consuming different forms of water,this study revealed that solid water consumption had the greatest effects on body weight,feed intake,water consumption,and fecal flora of mice.The abundance and diversity of fecal flora in mice were affected by different pH values of drinking water,especially acidified water.

Objective To investigate the spatiotemporal distribution characteristics and potential influencing factors of newly diagnosed echinococcosis cases in Qinghai Province from 2016 to 2022, so as to provide insights into the formulation of the echinococcosis control strategy in Qinghai Province. Methods The number of individuals screened for echinococcosis, number of newly diagnosed echinococcosis cases, number of registered dogs and number of stray dogs were captured from the annual reports of echinococcosis control program in Qinghai Province from 2016 to 2022, and the detection of newly diagnosed echinococcosis cases was calculated. The number of populations, precipitation, temperature, wind speed, sunshine hours, average altitude, number of year-end cattle stock, number of year-end sheep stock, gross domestic product (GDP) per capita, and number of village health centers in each county (district) of Qinghai Province were captured from the Qinghai Provincial Statistical Yearbook, and county-level electronic maps in Qinghai Province were downloaded from the National Platform for Common Geospatial Information Services. The software ArcGIS 10.8 was used to map the distribution of newly diagnosed echinococcosis cases in Qinghai Province, and the spatial autocorrelation analysis of newly diagnosed echinococcosis cases was performed. In addition, the spacetime scan analyses of number of individuals screened for echinococcosis, number of newly diagnosed echinococcosis cases and geographical coordinates in Qinghai Province were performed with the software SaTScan 10.1.2, and the spatial stratified heterogeneity of the detection of newly diagnosed echinococcosis cases was investigated with the software GeoDetector. Results A total of 6 569 426 residents were screened for echinococcosis in Qinghai Province from 2016 to 2022, and 5 924 newly diagnosed echinococcosis cases were found. The detection of newly diagnosed echinococcosis cases appeared a tendency towards a decline over years from 2016 to 2022 (χ² = 11.107, P < 0.01), with the highest detection in Guoluo Tibetan Autonomous Prefecture in 2017 (82.12/10⁵). There were spatial clusters in the detection of newly diagnosed echinococcosis cases in Qinghai Province from 2016 to 2018 (Moran’s I = 0.34 to 0.65, all Z values > 1.96, all P values < 0.05), and the distribution of newly diagnosed echinococcosis cases appeared random distribution from 2019 to 2022 (Moran’s I = −0.09 to 0.04, all Z values < 1.96, all P values > 0.05). Local spatial autocorrelation analysis showed high-high clusters and low-low clusters in the detection of new diagnosed echinococcosis cases in Qinghai Province from 2016 to 2022, and space-time scan analysis showed that the first most likely cluster areas of newly diagnosed echinococcosis cases in Qinghai Province from 2016 to 2022 were mainly distributed in Yushu Tibetan Autonomous Prefecture and Guoluo Tibetan Autonomous Prefecture. GeoDetector-based analysis of the driving factors for the spatial stratified heterogeneity of detection of newly diagnosed echinococcosis cases in Qinghai Province showed that average altitude, number of village health centers, number of cattle and sheep stock, GDP per capita, annual average sunshine hours, and annual average temperature had a strong explanatory power for the spatial distribution of newly diagnosed echinococcosis cases, with q values of 0.630, 0.610, 0.600, 0.590, 0.588, 0.537 and 0.526, respectively. Conclusions The detection of newly diagnosed echinococcosis cases appeared a tendency towards a decline in Qinghai Province over years from 2016 to 2022, showing spatial clustering. Targeted control measures are required in cluster areas of newly diagnosed echinococcosis cases for further control of the disease.

Bacterial outer membrane vesicles (OMVs) are diminutive vesicles naturally released by Gram-negative bacteria. These vesicles possess distinctive characteristics that attract attention for their potential use in drug administration and immunotherapy in cancer treatment. Therapeutic medicines may be delivered via OMVs directly to the tumor sites, thereby minimizing exposure to healthy cells and lowering the risk of systemic toxicity. Furthermore, the activation of the immune system by OMVs has been demonstrated to facilitate the recognition and elimination of cancer cells, which makes them a desirable tool for immunotherapy. They can also be genetically modified to carry specific antigens, immunomodulatory compounds, and small interfering RNAs, enhancing the immune response to cancerous cells and silencing genes associated with disease progression. Combining OMVs with other cancer treatments like chemotherapy and radiation has shown promising synergistic effects. This review highlights the crucial role of bacterial OMVs in cancer, emphasizing their potential as vectors for novel cancer targeted therapies. As researchers delve deeper into the complexities of these vesicles and their interactions with tumors, there is a growing sense of optimism that this avenue of study will bring positive outcomes and renewed hope to cancer patients in the foreseeable future.
