Objective To evaluate the molluscicidal effect and cost of spraying molluscicides with drones against Oncomelania hupensis snails in marshland and lake areas, so as to provide new insights into field snail control in China. Methods A marshland and lake setting measuring approximately 12 000 m² was selected in Wanzhi District, Wuhu City on June 2023 as the test field, and assigned to four groups, of 3 000 m² in each group. Environmental cleaning was not conducted in groups A or B, which were given 5% niclosamide ethanolamine salt granules sprayed with knapsack-type sprayers and drones at a dose of 40 g/m², and environmental cleaning was conducted in groups C and D, which were given 5% niclosamide ethanolamine salt granules sprayed with drones and knapsack-type sprayers at a dose of 40 g/m², respectively. O. hupensis snails were surveyed before chemical treatment and 1, 3, 5, 7, 14 days post-treatment. The uniformity of chemicals was determined on the day of treatment, and the snail mortality, corrected snail mortality and density of living snails were calculated and compared among groups. The cost of molluscicides, labor fees of environmental cleaning and chemical treatment and cost of equipment were calculated, and the cost for a 1% reduction in the mean density of living snails was calculated 14 days post-treatment. Results The mean densities of living snails and mortality rates of snails were 1.82 to 2.85 snails/0.1 m² and 1.41% to 2.94% in groups A, B, C and D before chemical treatment, and the mortality and corrected mortality of snails were 55.75%, 49.32%, 85.94% and 87.50%, and 55.00%, 48.47%, 85.70% and 87.29% in groups A, B, C and D 14 days post-treatment. There was a significant difference in the mortality of snails among the four groups 14 days post-treatment (χ² = 38.735, P < 0.005), and there was a higher snail mortality in Group D than in Group A (χ² = 16.876, P < 0.005), and higher in Group C than in Group B (χ² = 20.508, P < 0.005). The density of living snails reduced by 55.00%, 43.94%, 90.43% and 87.14% 14 days post-treatment relative to pre-treatment in groups A, B, C and D, respectively. The test for uniformity of chemicals showed that the mean dose of molluscicides were 57.34, 55.21, 40.19 g/m² and 32.37 g/m² in groups A, B, C and D, respectively, and the minimal standard deviation (7.07) and coefficient of variation (0.18) of mean doses were seen in Group C. The costs for chemical treatment were 0.33 Yuan in groups A and B and 1.53 Yuan in groups C and D, respectively. The costs for a 1% reduction in the mean density of living snails were 17.82, 22.47, 50.73 Yuan and 52.56 Yuan in groups A, B, C, and D 14 days post-treatment, respectively. Conclusions The molluscicidal effect and cost of spraying 5% niclosamide ethanolamine salt granules with drones are comparable to manual spraying, and chemical treatment with drones are high in uniformity of molluscicides, time- and labor-saving, and feasible for applications in complex environments, which deserves widespread applications in the field of snail control.

Objective: To explore the clinical efficacy of Xiaoshuan enteric-coated capsule (XSECC) in treating cerebral infarction and its potential mechanism of action. Methods: Patients with acute ischemic stroke (AIS) of the qi deficiency and blood stasis type were randomly assigned to the control and observation groups. They were evaluated using the National Institutes of Health Stroke Scale (NIHSS), Activities of Daily Living (ADL), Hachinskilnchemic Scale (HIS), Barthel Index (BI), clinical efficacy scores, and TCM syndrome scores on days 0, 14, 30, and 90. Furthermore, VEGF and BDNF levels were measured on days 30 and 90. Finally, we analyzed the changes in each scale score and vascular neurological factor in both groups. Results: After 14 days of treatment, the difference values in NIHSS, ADL, and BI were higher, and TCM syndrome and clinical efficacy scores were increased in the observation group compared with those of the control group (all P < .05). After 30 days, the NIHSS, ADL, HIS, and TCM syndrome scores were decreased compared with those of the control group, while BI and clinical efficacy scores were increased (all P < .05). After 90 days, the difference value in ADL was higher, and TCM syndrome score was increased in the observation group compared with that of the control group (P = .047, P = .005, respectively). The levels of VEGF and BDNF were higher in the observation group than in the control group on days 14, 30, and 90 (all P < .05). VEGF and BDNF levels on day 0 were associated with prognosis of patients with AIS; therefore, they have a predictive value for the prognosis of acute cerebral infarction. Conclusions XSECC therapy can improve clinical outcomes in patients with acute and recurrent cerebral infarctions. Its mechanism of action may be associated with the secretion of VEGF and BDNF.

Background Injury is a major public health issue, and studying the correlation between temperature and injury in the context of climate change is of great significance for injury prevention and control. Objective To analyze the association between temperature and the volume of emergency medical service response due to injury in Chengdu. Methods Using a retrospective ecological study design, weather data in Chengdu were collected from 1 January 2022 to 31 December 2023 from Chengdu Meteorological Office, including daily average temperature, daily average relative humidity, average wind speed, average pressure, sunshine, and rainfall. Emergency medical service data were collected from an emergency medical service center in Chengdu. A distributional lag non-linear model was conducted to calculate the association between temperature and volume of emergency medical service response due to injury, and gender- and age-stratified analyses were followed to identify susceptible groups. Results Overall 219685 incidents of emergency medical service dispatching due to injury were collected during the study period. The top three injury causes were traffic accident (90765, 41.32%), poisoning (44101, 20.07%), and falling (44046, 20.05%). When daily average temperature exceeded 17.9 ℃, as the temperature rised, the volume of emergency medical service response for injury increased. In terms of the single-day lag effect, the risk of emergency medical service response for injury elevated on lag1 and persisted until lag6, the maximum daily effectwas observed on lag2, lag3 and lag4, and their relative risks associated with every 1℃ higher above 17.9 ℃ were both 1.08 times, 95%CIs were (1.03, 1.14), (1.04, 1.12), and (1.04, 1.16) respectively. Both men and women were susceptible to temperature, but on the same lag day, the men's RR value was higher than the women's. There was no statistical difference in the lag effect of temperature on the 0-17 age group; the lag effect on the 18-44 age group appeared on lag1, and lasted to lag6; that for the 45-64 age group appeared on lag1, and lasted to lag4; that for the 65 age group and over was only on lag 3 (RR: 1.05, 95%CI: 1.00, 1.10). Conclusion As the temperature rises, the volume of emergency medical service response due to injury is increased in Chengdu. In particular, the associated impact is significant on males and people aged 18-44 years old.

Purpose To explore the application value of clinical-ultrasound parameter model in secondary hyperparathyroidism(SHPT).Materials and Methods A total of 86 patients(134 lesions)with renal insufficiency who underwent maintenance hemodialysis in the First Affiliated Hospital of Shihezi University from October 2020 to August 2022 were included and divided into group 1 according to the level of parathyroid hormone(iPTH)(iPTH＜300 pg/ml),group 2(iPTH 300-800 pg/ml)and group 3(iPTH≥800 pg/ml),all patients underwent gray-scale parathyroid ultrasound and acoustic palpation tissue quantitative imaging examinations.The characteristics of glandular gray-scale ultrasound and virtual touch tissue imaging quantification parameters between different groups,combined with relevant clinical indicators,established a clinical-ultrasound parameter model,used multiple linear regression to analyze the correlation between the model and iPTH,explored the independent risk factors of iPTH,and evaluated this model to evaluate SHPT the value of.Results There were significant differences in dialysis age,phosphorus,alkaline phosphatase,serum creatinine,corrected calcium and phosphorus product,lesion size,number,echo,shear wave velocity(SWV)max,SWVcen,and SWVmean among the three groups(F/x2/H=6.396-53.524,all P＜0.05).Dialysis age,phosphorus,alkaline phosphatase,and SWVratio were independent influencing factors of iPTH level(β=0.514,0.422,0.226,-0.368,all P＜0.005).The area under the curve,sensitivity,specificity and accuracy of the model for diagnosing SHPT and predicting surgical treatment with iPTH levels of 300 pg/ml and 800 pg/ml were 0.967,95.00％,100.00％,97.73％and 0.824,77.42％,71.43％and 90.00％,respectively.Conclusion Dialysis age,phosphorus,alkaline phosphatase and SWVratio are independent influencing factors of iPTH level,and the clinical-ultrasound parameter model is of great value in accurately assessing the severity of SHPT.

This article reported a male neonate with lethal mitochondrial trifunctional protein deficiency (MTPD) caused by compound heterozygous variations in the HADHB gene. The patient presented with poor milk intake complicated by abnormal myocardial enzymes within 24 h after birth and was transferred to the Children's Hospital of Nanjing Medical University on day 4. Physical examination revealed no obvious abnormalities on admission. Laboratory examination showed increased creatine kinase isoenzyme and cardiac troponin levels, and electrocardiogram suggested sinus tachycardia and low QRS voltage in limb leads. Blood screening for metabolic abnormalities showed high levels of tetradecenyl carnitine and various 3-hydroxycarnitines. Heterozygous mutations of c.739C>T(p.Arg247Cys) and c.607C>T(p.Arg203Ter,272) were detected in the HADHB gene in the boy, which were pathogenic variants included in the Human Gene Mutation Database. Followed up to three months of age, the boy was readmitted to hospital due to poor milk intake for one week and poor response for 2 d after catching a cold. After admission, he quickly developed multiple organs dysfunction such as heart failure and respiratory failure, and then died. Lethal MTPD is rare with no effective treatment and poor prognosis. Lethal MTPD should be highly suspected when unexplained cardiomyopathy, hypoglycemia, acidosis and other metabolic abnormalities appear in the neonatal period, and an early diagnosis could be confirmed with genetic testing in the neonatal period.

Objective To investigate the expression levels of scf and c-kit under the regulation of Dahuang Lingxian prescription and the possible mechanism of its effect on gallbladder dynamics, and to provide a theoretical basis for Dahuang Lingxian prescription in preventing the development and recurrence of cholesterol gallstone. Methods A total of 45 specific pathogen-free healthy male guinea pigs were randomly divided into normal group, model group, and traditional Chinese medicine (TCM) group. The guinea pigs in the normal group were fed with normal diet, and those in the model group and the TCM group were fed with high-fat lithogenic diet. After 8 weeks of feeding, 5 guinea pigs were randomly selected from each group, and successful modeling was determined if gallstone was observed with the naked eye in more than 4 guinea pigs. After successful modeling, the guinea pigs in the TCM group were given Dahuang Lingxian prescription by gavage, and those in the model group were given an equal volume of normal saline by gavage. After 8 consecutive weeks of administration by gavage, gallbladder tissue samples were collected, and HE staining was used to observe the pathological changes of gallbladder tissue; Western blot was used to measure the expression level of tumor necrosis factor-α (TNF-α) in gallbladder tissue; immunohistochemistry was used to measure the protein expression levels of scf and c-kit in gallbladder smooth muscle tissue. A one-way analysis of variance was used for comparison of normally distributed continuous data between multiple groups, and the least significant difference multiple comparison method was used for further comparison between two groups. Results HE staining showed marked inflammation of gallbladder tissue in the model group, and compared with the model group, the TCM group had a significantly lower degree of inflammation. Western blot showed that the model group had the highest expression level of TNF-α in gallbladder tissue, followed by the TCM group and the normal group ( P < 0.05); immunohistochemistry showed that compared with the model group, the normal group and the TCM group had significantly higher protein expression levels of scf and c-kit in gallbladder smooth muscle tissue ( P < 0.05). Conclusion Dahuang Lingxian prescription can enhance the dynamic function of the gallbladder, possibly by upregulating the scf/c-kit signaling pathway in interstitial cells of Cajal in gallbladder.

The incidence of brain metastases in patients with non-small cell lung cancer (NSCLC) has increased as a result of improved local control rate and survival rate. Prophylactic cranial irradiation (PCI) has been proven to reduce the incidence of brain metastases and improve survival rate in patients with NSCLC. However, the value of PCI for NSCLC is still controversial. This paper reviews the progress of the efficacy and adverse reactions after PCI treatment for patients with NSCLC.

Cystic echinococcosis (CE), a zoonotic disease caused by Echinococcus granulosus at the larval stage, predominantly develops in the liver and lungs of intermediate hosts and eventually results in organ malfunction or even death. The interaction between E. granulosus and human body is incompletely understood. Exosomes are nanosized particles ubiquitously present in human body fluids. Exosomes carry biomolecules that facilitate communication between cells. To the best of our knowledge, the role of exosomes in patients with CE is not reported. Here, we isolated exosomes from the sera of patients with CE (CE-exo) and healthy donors and subjected them to liquid chromatography-tandem mass spectrometry analysis. Proteomic analysis identified 49 proteins specifically expressed in CE-exo, including 4 proteins of parasitic origin. The most valuable parasitic proteins included tubulin alpha-1C chain and histone H4. And 8 proteins were differentially regulated in CE-exo (fold change>1.5), as analyzed with bioinformatic methods such as annotation and functional enrichment analyses. These findings may improve our understanding about the interaction between E. granulosus and human body, and may contribute to the diagnosis and prevention of CE.
