Objective To assess the risk of human Spirometra mansoni infections and investigate the knowledge, attitude and practice (KAP) towards sparganosis mansoni among residents in Henan Province, so as to provide insights into formulation of the sparganosis mansoni control measures. Methods Qinling Village in Fugou County of Zhoukou City, Bali Village in Yancheng District of Luohe City, Duzhai Village in Puyang County of Puyang City and Doushan Village in Luoshan County of Xinyang City were sampled as survey sites in Henan Province from July to August 2023, and more than 40 frogs were sampled from ponds or streams in each survey site for detection of Sparganum mansoni infections. At least 150 residents were sampled using a cluster sampling method from each survey site, and the sero-prevalence of anti-S. mansoni IgG antibody was estimated. In addition, a questionnaire survey was conducted on the KAP towards sparganosis mansoni among participants, and the proportion of eligible KAP, rate of correct KAP and KAP scores were calculated. Results A total 229 frogs were collected from 4 survey sites in 2023, and the overall prevalence of S. mansoni infection was 4.37% (10/229) in frogs, with 7.75% (10/129) prevalence in wild frogs and 0 in farm-bred frogs. A questionnaire survey was performed among 649 residents sampled from 4 survey sites, and 649 serum samples were collected. The seroprevalence of anti-S.mansoni IgG antibody was 0.15% (1/649) and the overall proportion of eligible KAP was 23.73% (154/649) among participants. There were age- (χ² = 30.905, P = 0.000), educational level- (χ² = 41.011, P = 0.000), and occupation-specific proportions of eligible KAP among participants (χ² = 10.721, P = 0.005), and the proportion of eligible KAP decreased with age (χ² _trend = 22.717, P = 0.000) and increased with education levels (χ² _trend = 40.025, P = 0.000). The rates of correct KAP towards sparganosis mansoni were 40.81% (2 119/5 192), 96.66% (1 882/1 947) and 63.81% (3 727/5 841) (χ² = 1 913.731, P = 0.000) among residents, respectively. The rates of correct KAP towards sparganosis mansoni varied significantly among survey sites (χ² = 136.872, 42.347 and 255.157; all P values= 0.000, with the highest rate of correct knowledge (51.94%, 748/1 440) and practices (75.86%, 1 229/1 620) in Yancheng District of Luohe City and the highest rate of correct attitudes in Puyang County of Puyang City (99.11%, 446/450) (all P values< 0.05). Conclusions There is still a high transmission risk of sparganosis mansoni in Henan Province, and the KAP towards sparganosis mansoni is required to be improved among residents.

Objective To investigate the factors associated with unplanned readmission within 30 days after discharge in adult patients who underwent coronary artery bypass grafting (CABG) and to develop and validate a risk prediction model. Methods A retrospective analysis was conducted on the clinical data of patients who underwent isolated CABG at the Nanjing First Hospital between January 2020 and June 2024. Data from January 2020 to August 2023 were used as a training set, and data from September 2023 to June 2024 were used as a validation set. In the training set, patients were divided into a readmission group and a non-readmission group based on whether they had unplanned readmission within 30 days post-discharge. Clinical data between the two groups were compared, and logistic regression was performed to identify independent risk factors for unplanned readmission. A risk prediction model and a nomogram were constructed, and internal validation was performed to assess the model’s performance. The validation set was used for validation. Results A total of 2 460 patients were included, comprising 1 787 males and 673 females, with a median age of 70 (34, 89) years. The training set included 1 932 patients, and the validation set included 528 patients. In the training set, there were statistically significant differences between the readmission group (79 patients) and the non-readmission group (1 853 patients) in terms of gender, age, carotid artery stenosis, history of myocardial infarction, preoperative anemia, and heart failure classification (P<0.05). The main causes of readmission were poor wound healing, postoperative pulmonary infections, and new-onset atrial fibrillation. Multivariable logistic regression analysis revealed that females [OR=1.659, 95%CI (1.022, 2.692), P=0.041], age [OR=1.042, 95%CI (1.011, 1.075), P=0.008], carotid artery stenosis [OR=1.680, 95%CI (1.130, 2.496), P=0.010], duration of first ICU stay [OR=1.359, 95%CI (1.195, 1.545), P<0.001], and the second ICU admission [OR=4.142, 95%CI (1.507, 11.383), P=0.006] were independent risk factors for unplanned readmission. In the internal validation, the area under the curve (AUC) was 0.806, and the net benefit rate of the clinical decision curve analysis (DCA) was >3%. In the validation set, the AUC was 0.732, and the DCA net benefit rate ranged from 3% to 48%. Conclusion Females, age, carotid artery stenosis, duration of first ICU stay, and second ICU admission are independent risk factors for unplanned readmission within 30 days after isolated CABG. The constructed nomogram demonstrates good predictive power.

Objective To investigate the geographical distribution and seasonal fluctuations of visceral leishmaniasis vectors sandflies in Henan Province in 2023, so as to provide insights into the prevention and control of visceral leishmaniasis vectors. Methods A total of 23 counties (districts) were sampled from 18 cities of Henan Province from May to September, 2023 as sandfly surveillance sites, and sandflies were captured using human capture and light trapping methods. Following morphological identification, the changes in the sandfly density were calculated at different months and in different breeding habitats. Results A total of 406 light traps were set at sandfly surveillance sites in Henan Province from May to September, 2023, and a total of 3 137 female sandlies were captured, with an average density of 7.73 sandlies/(light·night). A total of 1 494 Phlebotomus chinensis sandflies were captured, including 1 222 female sandflies, with an average density of 3.01 sandflies/(light·night), and the highest density of P. chinensis was found in Gongyi City [17.00 sandflies/(light·night)]. A total of 5 544 sandflies were captured using the human capture method, including 230 P. chinensis, and the density of P. chinensis appeared a unimodal distribution, with a peak in early July [5.81 sandflies/(light·night)]. Among different breeding habitats, the highest P. chinensis density was detected in pigpens [4.50 sandflies/(light·night)]. Conclusions P. chinensis was predominantly distributed in hilly areas of northern and central-western Henan Province in 2023, and the sandfly density appeared a unimodal distribution. Intensified monitoring of visceral leishmaniasis vectors is recommended.

OBJECTIVE To observe the effects of liraglutide on cardiovascular metabolism， left ventricular structure and function of non-alcoholic fatty liver disease （NAFLD） patients with type 2 diabetes mellitus （T2DM）. METHODS Totally 351 NAFLD patients with T2DM were enrolled retrospectively， who visited the Department of Endocrinology in our hospital from January 2019 to December 2022. They were divided into control group （196 cases） and observation group （155 cases） according to different treatment regimens. The control group received conventional standard treatment， and the observation group was additionally given Liraglutide injection 0.6 mg/d subcutaneously once a day based on the control group， adjusted to 1.2 mg/d after 7 days. Both groups received regular treatment for more than 12 months. The propensity matching method was used to match the two groups of patients at a ratio of 1∶1. The cardiovascular metabolism indexes and cardiac ultrasound parameters were compared， and the correlation between left ventricular structure， function parameters and cardiovascular metabolism indexes was analyzed. RESULTS After propensity score matching， there was no significant difference in baseline clinical data between the two groups （each 155 cases） before treatment （P＞0.05）. After 12 months of treatment， the waist circumference， weight， body mass index （BMI）， systolic blood pressure （SBP）， fasting blood glucose （FBG）， glycosylated hemoglobin （HbA1c） and triglyceride （TG） of both groups， as well as the diastolic blood pressure （DBP）， total cholesterol （TC）， uric acid （UA） and left ventricular mass （LVM） of the observation group， exhibited a significant decrease compared to pre-treatment levels （P＜0.05）. The high-density lipoprotein cholesterol （HDL-C）， estimated glomerular filtration rate （eGFR）， and E/A ratio in both groups， as well as the aspartate aminotransferase （AST） in the control group and the left ventricular ejection fraction （LVEF） in the observation group， were all significantly increased compared with before treatment in the same group （P＜0.05）. Moreover， the improvement of the above indicators （except for TG and SBP） in the observation group was generally more significant than those in the control group （P＜0.05）. The left ventricular structure and functional parameters （LVM， LVEF， E/A ratio） of the two groups before and after treatment had varying degrees of correlation with the patients’ waist circumference， body weight， BMI， SBP， FBG and HbA1c. Moreover， BMI （observation group： β＝ 0.229， P＝0.004） and SBP （control group： β＝0.240， P＝0.004； observation group： β＝0.226， P＝0.007） were independent influential factors for LVM of the patients. CONCLUSIONS Liraglutide combined with conventional standard treatment can effectively control blood glucose in NAFLD patients with T2DM， reduce waist circumference， body weight and blood pressure， improve blood lipid disorders， and protect their cardiac structure and function.

Currently, the management of domestic laboratory developed test (LDT) is still in the exploration stage, and new plans and ideas need to be investigated that are suitable for our national development. By analyzing encountered issues, combining the actual needs of the government, healthcare reform, and patients, this article proposes that "promoting healthy development of LDT projects and focusing on the organic combination of patients′ interest protection and innovation support" is an important direction for LDT management, around which the new idea for LDT project management is proposed, that is, LDT management model targeting product registration. The core of this management model is to target product registration and to ensure low service fees for patients and continuous real-time data monitoring. Benefit and risk analysis demonstrate that this management model can to a larger extent balance the realistic demands of patients, medical institutions, in vitro diagnostics companies, and government management departments, which benefits promoting the perfection and development of LDT projects in our country.

【Objective】 To explore the diagnosis, treatment, prognosis and long-term follow-up of urogenital solitary fibrous tumor (SFT) and to differentiate the characteristics between benign and malignant SFT. 【Methods】 Clinical data of 20 patients with urogenital SFT treated in our hospital during Jan.2004 and Aug.2021 were respectively analyzed, including the general characteristics, clinical symptoms, imaging results, treatment methods, pathological results, and long-term follow-up results. 【Results】 Of the 20 cases, 9 cases had tumor in kidney, 7 in pelvic cavity, 3 in bladder and 1 in prostate.Six patients showed non-specific clinical symptoms, including lower extremity weakness, urodynia, dysuria, frequent urination with changes in stool habits, low back pain, and abdominal wall mass with abdominal pain, and the other 14 cases were asymptomatic.The median diameter of SFT was 5.2 cm (range:1.7-15.0 cm).All patients received surgical treatment, including robotic-assisted surgery in 8 cases, open surgery in 5 cases, laparoscopic surgery in 5 cases, and transurethral resection of tumor in 2 cases.CT plain scan showed high, low and mixed density soft tissue masses, and enhanced CT showed enhanced results.Pathology results revealed frequent nuclear divisions, morphological variations and necrosis in malignant SFT, which had higher expression of Ki-67 than benign SFT.The results of the modified Demicco prognostic risk stratification model showed that all malignant SFT cases were at intermediate risk. The DFS of the SFT radical tumor resection group was slightly longer than that of the simple tumor resection group but the difference was not statistically significant (P=0.203). 【Conclusion】 Markers such as CD34, Bcl2, STAT6 and CD99 are used to diagnose SFT, while Ki-67 and tumor necrosis are used to differentiate benign and malignant SFT.The modified Demicco prognostic risk stratification model plays an important role in predicting the prognosis of SFT.Surgical resection is the most common treatment with excellent prognosis.In addition, benign SFT has much better prognosis than malignant case.

Objective:To further improve the understanding of paroxysmal nocturnal hemoglobinuria (PNH), we retrospectively analyzed and summarized the clinical characteristics, treatment status, and survival status of patients with PNH in Zhejiang Province.Methods:This study included 289 patients with PNH who visited 20 hospitals in Zhejiang Province. Their clinical characteristics, comorbidity, laboratory test results, and medications were analyzed and summarized.Results:Among the 289 patients with PNH, 148 males and 141 females, with a median onset age of 45 (16-87) years and a peak onset age of 20-49 years (57.8% ). The median lactic dehydrogenase (LDH) level was 1 142 (604-1 925) U/L. Classified by type, 70.9% (166/234) were classical, 24.4% (57/234) were PNH/bone marrow failure (BMF), and 4.7% (11/234) were subclinical. The main clinical manifestations included fatigue or weakness (80.8%, 235/289), dizziness (73.4%, 212/289), darkened urine color (66.2%, 179/272), and jaundice (46.2%, 126/270). Common comorbidities were hemoglobinuria (58.7% ), renal dysfunction (17.6% ), and thrombosis (15.0% ). Moreover, 82.3% of the patients received glucocorticoid therapy, 70.9% required blood transfusion, 30.7% used immunosuppressive agents, 13.8% received anticoagulant therapy, and 6.3% received allogeneic hematopoietic stem cell transplantation. The 10-year overall survival (OS) rate was 84.4% (95% CI 78.0% -91.3% ) . Conclusion:Patients with PNH are more common in young and middle-aged people, with a similar incidence rate between men and women. Common clinical manifestations include fatigue, hemoglobinuria, jaundice, renal dysfunction, and recurrent thrombosis. The 10-year OS of this group is similar to reports from other centers in China.
