In addition, the trends in prevalence of schistosomiasis in humans and livestock and snail status were evaluated in Wuhan City from 2005 to 2023 using Mann-Kendall test and a Joinpoint regression model. Results Mann-Kendall test revealed a tendency towards a decline in the prevalence of human schistosomiasis (Z = -4.41, P < 0.01), prevalence of S. japonicum infections in humans (Z = -4.89, P < 0.01) and bovines (Z = -4.50, P < 0.01), areas of S. japonicum-infected snail habitats (Z = -3.91, P < 0.01), areas of snail habitats in inner embankments (Z = -2.28, P = 0.02), and actual areas of snail habitats (Z = -5.95, P < 0.01) in Wuhan City from 2005 to 2023. Joinpoint regression analysis showed an average annual reduction of 8.58% in the prevalence of human schistosomiasis in Wuhan City from 2005 to 2023 [average annual percent change (AAPC) = -8.58%, 95% confidence interval (CI): (-10.02%, -6.65%), P < 0.01], with two joinpoints in 2013 and 2016, respectively, and the tendency towards a decline showed statistical significance during the period from 2013 through 2016 [annual percent change (APC) = -34.41%, 95% CI: (-40.36%, -20.01%), P < 0.01]. The prevalence of S. japonicum human infections appeared an average annual reduction of 51.91% in Wuhan City from 2005 to 2023 [AAPC = -51.91%, 95% CI: (-58.12%, -44.25%), P < 0.01], with two joinpoints in 2014 and 2017, respectively, and the tendency towards a decline showed statistical significance during the period from 2014 through 2017 [APC = -98.17%, 95% CI: (-99.17%, -90.87%), P < 0.01]. The prevalence of S. japonicum infections in bovines appeared an average annual reduction of 53.12% in Wuhan City from 2005 to 2023 [AAPC = -53.12%, 95% CI: (-59.65%, -42.44%), P < 0.01], with two joinpoints in 2011 and 2014, respectively, and the tendency towards a decline showed statistical significance during the period from 2014 through 2017 [APC = -98.63%, 95% CI: (-99.44%, -90.93%), P < 0.01]. The areas of S. japonicum-infected snail habitats appeared an average annual reduction of 47.09% in Wuhan City from 2005 to 2023 [AAPC = -47.09%, 95% CI: (-52.92%, -38.26%), P < 0.01], with two joinpoints in 2011 and 2014, respectively, and the tendency towards a decline showed statistical significance during the period from 2011 through 2014 [APC = -97.27%, 95% CI: (-98.65%, -88.06%), P < 0.01]. The areas of snail habitats in inner embankments appeared an average annual reduction of 4.45% in Wuhan City from 2005 to 2023 [AAPC = -4.45%, 95% CI: (-5.18%, -3.82%), P < 0.01], with three joinpoints in 2011, 2015 and 2018, respectively, and statistical significance was seen in the tendency towards a decline during the period from 2005 through 2011 [APC = -16.38%, 95% CI: (-20.15%, -14.25%), P < 0.01]. In addition, the actual areas of snail habitats appeared an average annual reduction of 2.65% in Wuhan City from 2005 to 2023 [AAPC = -2.65%, 95% CI: (-2.89%, -2.40%), P < 0.01], with a joinpoint in 2013, and the tendency towards a decline showed statistical significance during the period from 2013 through 2023 [APC = -4.06%, 95% CI: (-4.66%, -3.58%), P < 0.01]. Conclusions The integrated schistosomiasis control programme achieved significant effectiveness in Wuhan City from 2005 to 2023, with a tendency towards a decline in morbidity due to schistosomiasis in humans and livestock and snail status. The integrated schistosomiasis control strategy with emphasis on management of the source of S. japonicum infections should continue to be implemented to consolidate the schistosomiasis control achievements and achieve the goal of schistosomiasis elimination in the city.

Objective To explore the characteristics of traditional Chinese medicine(TCM)syndrome,syndrome elements and their combination,and the distribution of TCM syndrome types in advanced non-small cell lung cancer(NSCLC)patients suffering from hypothyroidism after treatment with immune checkpoint inhibitors(ICIs).Methods The analysis was conducted on 168 patients with NSCLC at stage ⅢB-ⅣB confirmed by pathological findings,whose epidermal growth factor receptor/anaplastic lymphoma kinase(EGFR/ALK)was negative,and then suffering from hypothyroidism after treatment with ICIs from January 2020 to June 2023,who admitted to Zhongshan Hospital of Chinese Medicine Affiliated to Guangzhou University of Chinese Medicine.The patients'information collected by four diagnostic methods of TCM was analyzed,and then cluster analysis was used to explore the characteristics of TCM syndrome and the distribution of TCM syndrome types of immunotherapy-induced hypothyroidism in advanced NSCLC.Moreover,the distribution of TCM syndrome types in the patients with different genders,age groups,and hypothyroidism grades was analyzed.Results(1)The TCM syndrome of hypothyroidism appearing in 168 patients with advanced NSCLC after immunotherapy was characterized by deficiency type,which manifested as follows:cough,fatigue and weakness,amnesia,lusterless complexion,spontaneous sweating,dry skin,white sputum,unwilling to talk,dizziness,nocturnal polyuria,blurred vision,emaciation,poor skin elasticity,poor appetite or even anorexia,somnolence,long-term poor appetite,edema,insomnia,low voice,dull pain,light white color of fingernails,spitting,frequently intolerance of cold,thirst,bright pale complexion,preference of warmth and aversion to cold,thirst with preference of hot drink,dyspnea,frequent constipation,dry stools,puffiness of face and eyelid,dreaminess,abdominal fullness,lumbar pain,and weakness in defecation.The tongue manifestation and pulse condition were characterized by white and thin coating,pale-red tongue,tongue with tooth-marks,pale and enlarged tongue,pale tongue,deep pulse,slippery pulse,feeble pulse,weak cubital pulse,and thready pulse.(2)The disease-location syndrome elements usually involved in the lung,spleen,and kidney,and the disease-nature syndrome elements usually involved in qi deficiency,yang deficiency,blood deficiency,and water retention.(3)The cluster analysis yielded three syndrome types,and they were lung and spleen qi deficiency syndrome,kidney yang deficiency syndrome,and qi deficiency and water retention syndrome in decreasing sequence of occurrence frequency.(4)Statistically significant difference of the distribution of TCM syndrome types was presented in the patients with various age groups(P<0.01).Lung and spleen qi deficiency syndrome was the main syndrome type in the patients aged 60-69 years old,kidney yang deficiency syndrome was frequently seen in the patients being or over 70 years old,and qi deficiency and water retention syndrome was frequently seen in the patients less than 50 years old.No statistically significant difference of the distribution of TCM syndrome types was presented in the patients with various genders and in the patients with various grades of hypothyroidism(P>0.05).Conclusion The immunotherapy-induced hypothyroidism in patients with advanced NSCLC is usually differentiated as the TCM syndrome types of lung-qi and spleen-qi deficiency,kidney yang deficiency,and qi deficiency and water retention.Deficiency of healthy qi contributes to the fundamental pathogenesis of the development and progression of the disease.Clinicians should pay attention to the changes of symptoms in time and monitor the thyroid function indicators of the patients,thus to avoid serious immunotherapy-related adverse events(irAEs).

Objective To evaluate the impact of traditional Chinese medicine(TCM)syndromes on percutaneous microwave ablation(MWA)treatment in patients with colorectal cancer liver metastases(CRLM)and to construct a multidimensional prediction model prognostic based on TCM syndrome classification.Methods Clinical data were collected from 86 CRLM patients who underwent MWA at Zhongshan Hospital of Traditional Chinese Medicine between October 2012 and October 2023.The clinical information covered TCM syndrome types of qi-blood deficiency and spleen-kidney yang deficiency,tumor characteristics,and treatment parameters.Logistic regression was used to screen feature variables for constructing the prognostic predication model,and cross validation was performed to evaluate the prognostic predictive performance.Results(1)Among the 86 CRLM patients,31(36.05%)had spleen-kidney yang deficiency syndrome,while 55(63.95%)had qi-blood deficiency syndrome.(2)Compared to the patients with spleen-kidney yang deficiency syndrome,patients with qi-blood deficiency syndrome exhibited significantly long progression-free survival(PFS)and high progression-free survival rate(P＜0.01),while no significant differences were presented in the incidences of postoperative adverse events such as pain,fever,infection,liver function impairment,or ascites/pleural effusion among the patients with the two syndrome types(P＞0.05).(3)Multivariate logistic regression analysis revealed that TCM syndrome type,maximum diameter of metastatic liver tumor,timing of liver metastasis,and Ki-67 expression rate of primary tumors were the independent prognostic factors for 1-year PFS(P＜0.05 or P＜0.01).(4)The constructed model demonstrated high predictive accuracy for PFS,with an area under the receiver operating characteristic(ROC)curve(AUC)of 0.905(95%CI:0.830-0.980).Conclusion TCM syndromes have significant influence on the prognosis of CRLM patients undergoing MWA,and the patients with qi-blood deficiency syndrome have favorable prognosis.This study pioneers a multidimensional prognostic prediction model integrating TCM syndromes for MWA-treated CRLM patients,highlighting the unique value of TCM syndromes in assessing disease progression and predicting prognosis.

Objective To analyze the trends in Oncomelania hupensis distribution in Wuhan City, Hubei Province from 2003 to 2022, so as to provide insights into precision schistosomiasis control. Methods Data pertaining to O. hupensis snail survey in Wuhan City from 2003 to 2022 were collected. The trends in the proportion of areas with snail habitats, actual area with snail habitats, mean density of living snails and prevalence of Schistosoma japonicum infection in snails were evaluated in schistosomiasis-endemic areas of Wuhan City from 2003 to 2022 with the slope of trend curve (β), annual percent change (APC) and average annual percent change (AAPC) using a Joinpoint regression model. Results During the period from 2003 through 2022, there were two turning points for the proportion of areas with snail habitats in Wuhan City in 2005 and 2015, with a rise during the period from 2003 to 2005 (β₁ = 5.93, t = 1.280, P > 0.05), a decline from 2005 to 2015 (β₂ = −0.88, t = −2.074, P > 0.05) and a rise from 2015 to 2022 (β₃ = 1.46, t = −2.356, P < 0.05). During the period from 2003 through 2022, there were two turning points for the proportion of areas with snail habitats in islet endemic areas of Wuhan City in 2006 and 2015, with no significant differences in the trends from 2003 to 2006 (β₁ = 4.64, t = 1.888, P > 0.05) or from 2006 to 2015 (β₂ = −1.45, t = −2.143, P > 0.05), and with a tendency towards a rise from 2015 to 2022 (β₃ = 2.04, t = −3.100, P < 0.05). During the period from 2003 through 2022, there were two turning points for the proportion of areas with snail habitats in inner embankment endemic areas of Wuhan City in 2012 and 2020, with a tendency towards a decline from 2003 to 2012 (β₁ = −0.39, t = −4.608, P < 0.05) and with no significant differences in the trends from 2012 to 2020 (β₂ = 0.03, t = 0.245, P > 0.05) and from 2020 to 2022 (β₃ = 1.38, t = 1.479, P > 0.05). During the period from 2003 to 2022, the actual area with snail habitats all appeared a tendency towards a decline in Wuhan City, and in islet and inner embankment endemic areas of Wuhan City from 2003 to 2022 (AAPC = −2.39%, −5.75% and −2.35%, all P values < 0.05). The mean density of living snails reduced from 0.087 snails/0.1 m² in 2003 to 0.027 snails/0.1 m² in 2022 in Wuhan City, with a significant difference in the tendency towards the decline (APC = AAPC = −11.47%, P < 0.05). The annual mean decline rate of the mean density of living snails was 17.36% in outside embankment endemic areas of Wuhan City from 2003 to 2022 (APC = AAPC = −17.36%, P < 0.05), and there was no significant difference in the trends in the mean density of living snails in islet endemic areas of Wuhan City from 2003 to 2022 (APC = AAPC = −0.97%, P > 0.05). In addition, the prevalence of S. japonicum infection in snails appeared a tendency towards a decline in Wuhan City from 2003 to 2022 (APC = AAPC = −12.45%, P < 0.05). Conclusions The proportion of areas with snail habitats, actual area with snail habitats, mean density of living snails and prevalence of S. japonicum infection in snails all appeared a tendency towards a decline in Wuhan City from 2003 to 2022. Intensified snail control, modification of snail habitats, shrinking of areas with snails and implementation of grazing prohibition in snail-infested settings are required, in order to facilitate the progress towards schistosomiasis elimination in Wuhan City.

Objective　To analyze and visualize the epidemic changes of schistosomiasis in Wuhan from 2013 to 2022 based on a geographical information system (GIS), providing references for further schistosomiasis control activities. Methods　According to the historical data of the annual reports of schistosomiasis screening and street-level vector map of Wuhan City from 2013 to 2022, a spatial database of epidemic information at the street level was established. The Joinpoint regression model was utilized to analyze the trend of phased changes in blood positivity rate for schistosomiasis. ArcMap 10.8 was employed for the spatial visualization of the positive rate of serological tests for schistosomiasis among the screened population in the endemic areas of Wuhan over the past decade, as well as conducting hot spot analysis (Getis-Ord Gi*) to explore the spatial clustering relationship and spatiotemporal trends. Heatmaps were generated to reflect the changes in the positive rate of blood tests for schistosomiasis over a decade in various streets, and the areas were classified by the ward’s method of hierarchical clustering using the sum of squared deviations. Results　Over the past decade, the overall annual positive rate of schistosomiasis screening in Wuhan declined from 2.23% in 2013 to 0.47% in 2022, showing a general downward trend. The Joinpoint regression model analysis of the blood positive rate indicated the presence of one connection point in 2015; from 2013 to 2015, the annual percent change (APC) of the positive rate was 2.17%, showing an upward trend (P>0.05); from 2015 to 2022, the APC was -23.34%, indicating a downward trend (P<0.05). The map of positive street-level schistosomiasis screening rates for 2013-2022 shows that the positive rate count on the streets of Caidian District and Hannan District in southwestern Wuhan and Huashan Street on the east side, had a significant decrease over the ten years, while the rate in the streets under the jurisdiction of Dongxihu District in the west showed an increase. The hot spot analysis graph revealed that hot spots of the positive rate in Wuhan shifted from the southwest to the west beginning in 2018. The heatmap indicated the largest disparity in trend changes, with the most noteworthy decline in streets under Caidian District and an increasing trend in the streets under Dongxihu District. Conclusions　The overall epidemic situation of schistosomiasis in Wuhan is on a downtrend, although the positive rate of blood tests has increased in some areas. This has been attributed to a reduction in the total number of people participating in the blood tests and the slow decrease of antibodies in certain patients who were repeatedly sampled for testing. It is important to further strengthen the construction of monitoring capabilities, improve the sensitivity of monitoring systems, identify potential risks promptly, and handle them properly.

Objective:To compare the effect of modified postauricular transverse incision and traditional vertical incision for microvascular decompression in the treatment of hemifacial spasm.Methods:Prospective study method was used. A total of 116 patients with hemifacial spasm in Handan Central Hospital from January 1, 2019 to January 1, 2020 were selected, and divided into two groups according to the admission order. Both groups underwent microvascular decompression; control group (57 cases) received traditional vertical incision, while treatment group (59 cases) received modified postauricular transverse incision. The brainstem auditory evoked potential (BAEP), pain degree, surgical indicators, facial aesthetic satisfaction and complications were compared between two groups.Results:After treatment, the BAEP of latency, wave interval and wave amplitude in the two groups increased compared with that before treatment, and the BAEP of latency, wave interval and wave amplitude in the treatment group were higher than those in the control group: (1.89 ± 0.15) ms vs. (1.62 ± 0.21) ms, (7.89 ± 0.15) ms vs. (6.25 ± 0.41) ms, (1.79 ± 0.19) ms vs. (1.54 ± 0.11) ms ( P<0.05). After treatment, the visual analogue score (VAS) of patients in the two groups decreased compared with that before treatment, and the VAS of patients in the treatment group was lower than that in the control group: (1.15 ± 0.27) points vs. (2.18 ± 0.24) points ( P<0.05). The operation time, intraoperative bleeding volume and postoperative scar length of patients in the treatment group were less than those in the control group: (60.41 ± 3.81) h vs. (76.87 ± 3.87) h, (30.18 ± 4.19) ml vs. (56.87 ± 4.15) ml and (4.18 ± 1.07) cm vs. (6.87 ± 1.05) cm ( P<0.05). The satisfaction rate of patients in the treatment group was higher than that in the control group: 91.53% (54/59) vs. 71.93% (41/57) ( P<0.05). The complication rate of patients in the treatment group was lower than that in the control group: 5.08% (3/59) vs. 21.05% (12/57) ( P<0.05). Conclusions:Compared with traditional vertical incision, the modified transverse incision for microvascular decompression in the treatment of hemifacial spasm can reduce intraoperative blood loss and postoperative scar area, enhance brainstem auditory evoked potential, and improve facial aesthetics, which is worthy of recommendation.

Hydrogen peroxide (H2O2) plays a significant role in regulating a variety of biological processes. Dys-regulation of H2O2 can lead to various diseases. Although numerous fluorescent imaging probes for H2O2 have been reported, the development of H2O2 ratiometric fluorescent probe with large Stokes shift re-mains rather limited. Such probes have shown distinct advantages, such as minimized interference from environment and improved signal-to noise ratio. In this work, we reported a new pyrene-based com-pound Py-VPB as H2O2 fluorescent probe in vitro. The probe demonstrated ratiometric detection behavior, large Stokes shift and large emission shift. In addition, the probe showed high sensitivity and selectivity towards H2O2 in vitro. Based on these excellent properties, we successfully applied Py-VPB to the visualization of exogenous and endogenous H2O2 in living cells. Cell imaging study also showed that our probe was localized in the mitochondria. We envision that the probe can provide a useful tool for unmasking the biological roles of mitochondrial H2O2 in living systems.

Objective:To compare the effects ofpropofol and sevoflurane on the plasma thromboxane B2 (TXB2),endothelin-1 (ET-1) and D-dimer (D-D) levels of patients underwent posterior retroperitoneal laparoscopic surgery.Methods:84 cases of patients underwent post retroperitoneal laparoscopic surgery in our hospital from May 2015 to December 2016 were selected as research objectives and randomly divided into two groups with 42 cases in each group.The same anesthesia induction were provided for two groups,the observation group was given 2％～3％ sevoflurane for continuous inhalation,while the control group was given 4～12 mg/(kg·h) of propofol for continuous injection by pump.Both groups received remifentanil 10 μg/ (kg ·h) target-controlled infusion simultaneously.The levels of plasma TXB2,ET-1 and D-D in the two groups were measured after anesthesia induction (T0),at 0.5 h (T1),1 h (T2),1.5 h (T3) after pneumoperitoneum.Meanwhile,the anesthetic effects and adverse reactions were compared between two groups.Results:The time of consciousness disappearence,time of tracheal intubation,spontaneous breathing recovery time,eye opening time,verbal response time,orientation recovery time and extubation time of observation group were significantly shorter than those of the control group (P＜0.01).No significant difference was found in the occurrence of adverse reactions between two groups (P＞0.05).The plasma TXB2,ET-1 and D-D levels of both groups were gradually increased at T1,T2 and T3,and all were significantly higher than that at T0 (P＜0.01).The plsma TXB2,ET-1 and D-D levels at T1,T2 and T3 of observation group were significantly lower than those of the control group at same time (P＜0.01).Conclusion:Posterior laparoscopic surgery could cause different degrees of hypercoagulability of blood.Compared with propofol,sevoflurane could effectively inhibit the release of TXB2,ET-1 and D-D in anesthesia after retroperitoneal laparoscopic anesthesia,and play a better role of anticoagulation.
