The distribution of Ixodes and Ana plasma carried by Ixodes ticks in Anhui Province was clarified as reference for prevention and control of anaplasmosis.In total,630 hard ticks were collected from Jinzhai County,Hanshan County,Jing-de County and Chaohu City in Anhui Province from April to August 2023.Ticks were identified by morphological analysis and 16S rRNA sequencing.Nested PCR with Anaplasma species-specific primers were used to detect 16S rRNA of Anaplasma spe-cies carried by ticks.A phylogenetic tree was constructed using MEGA11.0 software.Of the identified ticks,18.8％(18/96)were Rhipicephalus microplus and 81.2％(78/96)were Haemaphysalis longicorni in Jinzhai County of Anhui Province,all were H.longicorni in Hanshan County and Chaohu City,while the main species in Jingde County was R.microplus.The posi-tive rate of Anaplasma carried by H.longicornis was 30.9％(102/330),which included A.bovis at 1.8％(6/330),A.phagocytophilum at 21.8％(72/330)and uncultured Anaplasma species at 7.3％(24/330).R.microplus was positively cor-related to A.bovis(13.6％,18/132).The uncultured Anaplasma species was mainly detected in host-free ticks.A.phagocy-tophilum was detected in 24.4％of parasitic ticks and 15.8％of host-free ticks.The positive rates of host-free and parasitic ticks were 19.9％and 17.8％,respectively.These results show that H.longicornis and R.microplus were the dominant ticks in several counties of Anhui Province.H.longicornis and R.microplus as well as free and parasitic ticks all carried Anaplas-ma.

Growing clinical evidence shows that Qufeng Gutong Cataplasm may exert a significant analgesic effect. However, the pharmacological characteristics and mechanisms underlying this prescription are still unclear. In the current study, a "disease-syndrome-symptom-formula" association network analysis was performed to explore the pharmacological characteristics and mechanisms of Qufeng Gutong Cataplasm against osteoarthritis (OA), neuropathic pain (NP), chronic inflammatory pain (CIP) and myofascial pain syndrome (MPS) by integrating clinical phenomics data, transcriptomics data and biological interaction network mining. As a result, the three functional modules (Qufeng Sanhan-QFSHG, Shujin Huoxue-SJHXG and Xiaozhong Zhitong-XZZTG) enriched by the drug network targets were all related to the pharmacological effects of Qufeng Gutong Cataplasm, including dispersing cold and relieving pain, activating blood and relieving pain, reducing swelling and relieving pain. In addition, the main pharmacological effects of QFSHG and XZZTG were dispelling wind and dispersing cold and dehumidifying, promoting Qi and reducing swelling and relieving pain, respectively. In terms of reversing the imbalance of "immune-inflammation-vascular axis", the main pharmacological effects of SJHXG were regulating the liver and promoting Qi, activating blood circulation and removing stasis. Mechanically, the key network targets of Qufeng Gutong Cataplasm against OA, NP, CIP and MPS may play a therapeutic role in relieving hyperalgesia and paresthesia by reversing the "neuro-endocrine-immune" imbalance system during the occurrence and progression of diseases. In conclusion, our data indicate that Qufeng Gutong Cataplasm may relieve the pain and wind-cold-dampness arthralgia syndrome related symptoms by regulating the "neuro-endocrine-immune" system, neurological and endocrine disorders and reversing the imbalance of "immunity-inflammation". The relevant results may provide a network-based evidence for clinical positioning of Qufeng Gutong Cataplasm, and offer a direction for further clinical and experimental validation.

Objective To investigate the prevalence of Schistosoma japonicum infection in wild mice in Shitai County, Anhui Province, so as to provide insights into precise control of the source of S. japonicum infections. Methods Wild mice were captured using the trapping method for three successive nights at snail-infested settings from Jitan Village of Jitan Township, and Shiquan Village and Xibai Village of Dingxiang Township, Shitai County, Anhui Province in June and October, 2018. All trapped wild mice were sacrificed and liver and mesenteric vein specimens were collected for detection of S. japonicum eggs using microscopy, while the fecal samples in mouse intestines were collected for identification of S. japonicum infections using Kato-Katz technique. In addition, the population density of trapped wild mice was estimated and the prevalence of S. japonicum infection was calculated in trapped wild mice. Results A total of 376 wild mice were trapped from three villages in Shitai County. The population density of trapped wild mice was 9.1% (376/4 124), and the prevalence of S. japonicum infection was 24.2% (91/376) in trapped wild mice. The highest prevalence of S. japonicum infection was detected in Shiquan Village of Dingxiang Township (30.1%), and the lowest prevalence was seen in Xibai Village of Dingxiang Township; however, there was no significant difference in the prevalence of S. japonicum infection in trapped wild mice among three villages (χ²= 4.111, P > 0.05). In addition, there was no significant difference in the prevalence of S. japonicum infection in wild mice captured between on June (26.8%, 34/127) and October (22.9%, 57/249) (χ² = 0.690, P = 0.406). The trapped wild mice included 6 species, including Rattus norvegicus, Niviventer niviventer, R. losea, Apodemus agrarius, Mus musculus and N. coning, and the two highest prevalence of S. japonicum infection was detected in R. losea (34.9%, 22/63) and R. norvegicus (31.2%, 44/141). Conclusions The prevalence of S. japonicum infections is high in wild mice in Shitai County, and there is a natural focus of schistosomiasis transmission in Shitai County.

Objective:To explore the mechanism and compatibility characteristics of Baimai ointment （BMO） in the treatment of white vein disease from the network perspective based on system theory， so as to provide biological basis for its clinical application. Method:The chemical components and the corresponding candidate target spectra of BMO were obtained from The Encyclopedia of Traditional Chinese Medicine （ETCM） and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine （TCMIP）. According to the clinicopathological characteristics of white vein disease， focusing on four diseases/symptoms including neuropathic pain， inflammatory pain， chronic pain and lumbar disc herniation root neuralgia， the gene sets related to white vein disease were collected in Human Phenotype Ontology （HPO）， DisGeNET and other databases， then the interaction network of the targets of active components in BMO-gene sets related to white vein disease was constructed. On this basis， the hub network nodes were selected and enriched for exploring the mechanism of four functional groups of BMO in the treatment of white vein disease such as Huoxue Tongluo group （Curcumae Longae Rhizoma， Moschus， Tronae）， Xingqi Zhitong group （Myristicae Semen， Nardostachyos Radix et Rhizoma， Acori Calami Rhizoma）， Wenjing Sanhan Tongluo group （Zingiberis Rhizoma， Zanthoxyli Pericarpium， Caraway） and Jianpi Wenshen Qianggu group （Actinolite， Glycyrrhizae Radix et Rhizoma）. Result:The enriched pathways of the four functional groups in BMO were mainly distributed in three modules of nervous system function， inflammation-immune system regulation and body energy metabolism， and each module was connected by common target genes especially had its own focus. Among them， the regulation of nervous system function in Huoxue Tongluo group and Xingqi Zhitong group could be summarized as Huoxue Buqi and Xingshen Kaiqiao. Xingqi Zhitong group and Jianpi Wenshen Qianggu group were mainly used to promote the operation of Qi， promote blood metaplasia， enhance immunity and maintain the regulation of inflammation-immune system. Jianpi Wenshen Qianggu group and Wenjing Sanhan Tongluo group mainly regulated body energy metabolism by invigorating the spleen and supplementing Qi as well as warm-heat medicine. The whole formula focused on the multi-dimensional and multi-level mechanism of BMO in the intervention of white vein disease. Each functional group emphasized its respective characteristics in nervous system function， inflammation-immune regulation， and body energy metabolism. Two types of networks analysis models complemented and verified each other. Conclusion:BMO plays a role in the treatment of white vein disease mainly by regulating the function of nervous system， maintaining the balance of inflammation-immune system and interfering with energy metabolism. The relevant research results can provide reference for the in-depth exploration of the mechanism of BMO， and help to guide the clinical rational use of this preparation.

Objective: To determine the impact of inflammatory reaction levels and the culprit plaque characteristics on preprocedural Thrombolysis in Myocardial Infarction (TIMI) flow grade in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Methods: The is a retrospective study. A total of 1 268 STEMI patients who underwent pre-intervention optical coherence tomography (OCT) examination of culprit lesion during emergency PCI were divided into 2 groups by preprocedural TIMI flow grade (TIMI 0-1 group (n =964, 76.0%) and TIMI 2-3 group (n =304, 24.0%)). Baseline clinical data of the 2 groups were collected; blood samples were collected for the detection of inflammatory markers such as high sensitivity C-reactive protein (hsCRP), myocardial injury marker, blood lipid, etc.; echocardiography was used to determine left ventricular ejection fraction; coronary angiography and OCT were performed to define the lesion length, diameter stenosis degree of the infarct-related arteries, presence or absence of complex lesions, culprit lesion type, area stenosis degree and vulnerability of culprit plaques. Multivariable logistic regression analysis was performed to identify independent correlation factors. The receiver operating characteristic (ROC) curve of continuous independent correlation factors was analyzed, and the best cut-off value of TIMI 0-1 was respectively determined according to the maximum value of Youden index. Results: The mean age of 1 268 STEMI patients were (57.6±11.4) years old and 923 cases were males (72.8%). Compared with TIMI 2-3 group, the patients in TIMI 0-1 group were older and had higher N-terminal-pro-B-type natriuretic peptide level, lower cardiac troponin I (cTnI) level, lower left ventricular ejection fraction, and higher hsCRP level (5.16(2.06, 11.78) mg/L vs. 3.73(1.51, 10.46) mg/L). Moreover, the hsCRP level of patients in TIMI 0-1 group was higher in the plaque rupture subgroup (all P<0.05). Coronary angiography results showed that compared with TIMI 2-3 group, the proportion of right coronary artery (RCA) as the infarct-related artery was higher, the angiographical lesion length was longer, minimal lumen diameter was smaller, and diameter stenosis was larger in TIMI 0-1 group (all P<0.05). The prevalence of plaque rupture was higher (75.8% vs. 61.2%) in TIMI 0-1 group. Plaque vulnerability was significantly higher in TIMI 0-1 group than that in TIMI 2-3 group with larger mean lipid arc (241.27°±46.78° vs. 228.30°±46.32°), more thin-cap fibroatheroma (TCFA, 72.4% vs. 57.9%), more frequent appearance of macrophage accumulation (84.4% vs. 70.7%) and cholesterol crystals (39.1% vs. 25.7%). Minimal flow area was smaller [1.3(1.1-1.7)mm² vs. 1.4(1.1-1.9)mm², all P<0.05] and flow area stenosis was higher (78.2%±10.6% vs. 76.3%±12.3%) in TIMI 0-1 group. Multivariable analysis showed that mean lipid arc>255.55°, cholesterol crystals, angiographical lesion length>16.14 mm, and hsCRP>3.29 mg/L were the independent correlation factors of reduced preprocedural TIMI flow grade in STEMI patients. Conclusions: Plaque vulnerability and inflammation are closely related to reduced preprocedural TIMI flow grade in STEMI patients.

Objective:To observe the effect of gait training assisted by an end-effector-based robot on the gait, balance, walking and general lower limb motor functioning of stroke survivors.Methods:Thirty-nine stroke survivors were randomized into a training group ( n=21) and a control group ( n=18). In addition to routine hemiplegia rehabilitation, the control group was given medium frequency electrical stimulation while the training group underwent 20 minutes of gait training assisted by an end-effector-based robot six days a week for 4 weeks. Before and after the intervention, both groups were evaluated using the functional ambulatory categories (FAC), the Fugl-Meyer lower extremity assessment, the Wisconsin Gait Scale and the Berg balance scale (BBS). Results:There were no significant differences between the groups before the intervention. Afterward significant improvement was observed in both groups in all measurements, with the training group scored better in terms of FAC and BBS.Conclusion:Using an end-effector-based robot in gait training might be more advantageous for improving the gait, balance, walking and general lower limb functioning of stroke survivors.

Aim To investigate the influence of different concentrations of dextran sulfate sodium (DSS) and administration approaches on the establishment of mouse model of acute ulcerative colitis(UC). Methods Mice were randomly divided into the normal control group, 3% DSS free drinking group, 4% DSS free drinking group, 30% DSS intragastric administration group and 40% DSS intragastric administration group. The amount and average dosage of intaken DSS by mice in free drinking group were measured and the intragastric administration group were given the same dosage. The survival rate, disease activity index (DAI), the lengths and pathological changes of colon were observed, and the coefficients of variation of each indicator described above were compared among the groups. Results Except for the normal control group, other groups developed experimental UC. Among these four approaches, 3% DSS solution free drinking showed appropriate incidence, higher animal survival rate and operability and lower cost, while there was no significant difference in the coefficients of variation of DAI between 3% DSS solution free drinking group and the others. Conclusion 3% DSS solution free drinking has more advantages in the establishment of a murine model with acute UC than other approaches.

On the basis of the chromogenic reaction between Hg and CuI, a semi-quantitative solid sampling Hg analyzer comprising the catalytic furance, Hg testing tube, air pump and smart cellphone was developed. White carrier 101 was chosen as the adsorbent for CuI to react with Hg from the catalytic furnace. The established Hg analyzer can not only visually recognize the coloration when Hg exceeding the limit standard, but also semi-quantitatively detect the Hg content in cosmetics fast using a smart cellphone and RGB analysis software, after direct solid sampling introduction of cosmetics sample. The instrumental detection limit ( LOD) of mercury was 50 ng, the linearity ranged from 50 ng to 2500 ng, the linear regression coefficient ( R2) was higher than 0. 97, and the RSD of the corresponding RGB values was 6% ( n=11 ) . Nine real cosmetics samples were measured by the established method, whose relative differences of Hg contents with that by the standard method (Safety Technical Specification for Cosmetics, 2015 edition) were less than 10% . The whole analytical time can be controlled within 5 min. The established instrumental method is simple, fast, accurate and visual, and extremely suitable to fast and on-site monitoring of Hg in cosmetics samples.
