Objective:To study echinococcosis in the population and canine Echinococcus infection in Yushu City, Qinghai Province, and to explore the current epidemic situation and main transmission species of Echinococcus. Methods:In June 2023, a multi-stage sampling method was used to select 2 villages each in Shanglaxiu Township and Longbao Town, Yushu City, Qinghai Province. Each village included at least 100 permanent residents who had lived locally for at least 1 year and were 2 years old or older as the survey subjects. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum antibodies against Echinococcus larvae in the population, and B-mode ultrasound was used for abdominal organ scanning. Meanwhile, on the main roads of Shanglaxiu Township and Longbao Town, canine feces were collected in designated areas at intervals. ELISA was used to detect the antigen of canine fecal Echinococcus, and PCR was used to detect the types of parasites ( Echinococcus multilocularis, Echinococcus granulosus and Echinococcus shiquicus). Results:A total of 511 residents were investigated in Yushu City, and the positive rate of serum Echinococcus larvae antibodies in the population was 26.22% (134/511), and the detection rate of echinococcosis B-mode ultrasound was 1.37% (7/511). Among them, the detection rates of B-mode ultrasound for cystic echinococcosis (CE) and alveolar echinococcosis (AE) were 1.17% (6/511) and 0.20% (1/511), respectively. The positive rate of Echinococcus antigen in 543 canine feces detected by ELISA was 12.89% (70/543). PCR was used to test 497 canine feces, and the detection rate of Echinococcus was 3.02% (15/497). Among them, the detection rate of Echinococcus multilocularis was higher than that of Echinococcus granulosus [2.82% (14/497) vs 0.20% (1/497)], and the difference was statistically significant (χ 2 = 11.44, P < 0.001). No Echinococcus shiquicus was detected. Conclusions:The positive rates of Echinococcus larvae antibodies in the population and canine Echinococcus antigen in Yushu City, Qinghai Province are both relatively high. There is a mixed epidemic of CE and AE, with Echinococcus multilocularis being the main species.

Objective:To investigate the effect of traditional Chinese medicine (TCM) lotion on incidence of postoperative infection and recurrence of refractory paronychia.Methods:Seventy-eight patients with intractable paronychia who received treatment at Hangzhou Third People's Hospital from January 2019 to November 2022 were included in this study. The patients were randomly divided into the povidone-iodine group ( n = 39) and the TCM lotion group ( n = 39) using the random number table method. Both groups underwent matrixectomy via a lateral incision and rhomboid flap excision surgery. Prior to the procedure, the povidone-iodine group received treatment with a 5% povidone-iodine solution, whereas the TCM lotion group was administered a TCM lotion containing Scutellaria barbata, Verbena, Lonicera japonica, Viola, Rheum palmatum, Atractylodes, Glauber's salt, Phellodendron, red peony root, Glycyrrhiza uralensis, and Magnolia officinalis. Both groups underwent treatment until the patients fulfilled the surgical indications and were subsequently observed for a period of 6 months post-surgery. The clinical efficacy was evaluated 1 month after the surgical intervention. A comparative analysis was conducted to assess the postoperative duration of redness and swelling, pus discharge, granulation, and pain resolution between the two groups. Additionally, the postoperative occurrence of wound-dressing adhesion, the status of wound healing, pain intensity at 1 and 3 days post-surgery, the incidence of infection at 1 week post-surgery, and the recurrence rates at 1 and 6 months post-surgery, were compared between the two groups. Results:At 1 month post-surgery, the total effective rate in the TCM lotion group was 92.31% (36/39), which was significantly higher than that in the povidone-iodine group [71.79% (28/39), χ2 = 4.26, P < 0.05]. The postoperative durations of redness and swelling, pus discharge, granulation, and pain resolution in the TCM lotion group were (5.66 ± 0.58) days, (3.64 ± 0.55) days, (8.42 ± 1.58) days, and (3.36 ± 0.32) days, respectively, which were significantly shorter than those in the povidone-iodine group [(6.73 ± 0.65) days, (4.56 ± 0.48) days, (9.77 ± 2.56) days, (3.89 ± 0.48) days, t = 7.67, 7.87, 2.80, 5.73, all P < 0.05]. The proportion of mild adhesion between the wound and dressing was significantly higher, while the proportion of severe adhesion was significantly lower, compared with the povidone-iodine group ( Z = 4.64, both P < 0.05). The durations of postoperative pain, the time to redness resolution, and wound healing time in the TCM lotion group were (4.22 ± 1.73) days, (3.02 ± 1.16) days, and (11.84 ± 2.50) days, which were significantly shorter than those in the povidone-iodine group [(8.53 ± 2.48) days, (5.20 ± 2.31) days, (13.32 ± 2.86) days, t = 8.90, 5.26, 2.43, all P < 0.001]. At 3 days post-surgery, pain scores in each group were significantly lower than the respective scores at 1 day post-surgery. At 1 and 3 days post-surgery, pain scores in the TCM lotion group were (3.30 ± 0.18) points and (2.28 ± 0.23) points, respectively, which were significantly lower than the respective scores in the povidone-iodine group [(3.61 ± 0.29) points, (2.52 ± 0.33) points, t = 5.67, 3.72, both P < 0.05]. There were no significant differences in the incidence of infection at 1 week post-surgery and the recurrence of refractory paronychia at 1 and 6 months post-surgery between the two groups (all P > 0.05). Conclusion:The combination of TCM lotion and matrixectomy through a lateral incision and rhomboid flap excision surgery for the treatment of refractory paronychia can help shorten pre-operative treatment time, minimizes postoperative wound-dressing adhesion, promote wound healing, alleviate postoperative pain, and decrease the incidence of infection and recurrence of refractory paronychia, demonstrating superior efficacy compared with treatment with a 5% povidone-iodine solution.

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.
