ABSTRACT

Objective To explore the pattern of early expression and secretion of tissue factor(TF)in vascular endothelial cells induced by heat stress.Methods Thirty SPF-rated C57BL/6 male mice were randomly divided into five groups:the control group and groups of indicated recovery time,including 0,3,6,and 9 h in room temperature after heat stress(n=6).Mice in the heat stress groups were exposed to an animal incubator to reach 42.5℃for core body temperature for heat stroke.We analyzed the histopathological changes in the liver,lung,and kidney tissues with HE staining.We measured the TF mRNA in mice tissues by RT-qPCR and the plasma concentration of TF in mice with a commercial ELISA kit.Human umbilical vein endothelial cells(HUVECs)were placed in a culture incubator to build an in vitro heat stress model.HUVECs were divided into five groups,including a control group and groups of indicated recovery time,including 0,3,6,and 9 h after heat stress.We quantified the expression of TF mRNA and protein in HUVEC cells by RT-qPCR,Western blotting,and immunofluorescence and measured the secreted TF with a commercial ELISA kit.Results No significant pathological injury was observed in the tissues of the control group.Mice treated with heat stress had various degrees of structural injuries and hemorrhagic and inflammatory changes in multiple tissues.Compared to control group,the expression of TF mRNA significantly increased in the kidney of heat stress-treated mice with 0 and 3 h recovery time(1.719±0.018,1.241±0.178 vs.1.000±0.063),the lung with 3 h recovery time(2.444±0.511 vs.1.000±0.106)and the liver with 6 h recovery time(7.312±0.618 vs.1.000±0.147)(P<0.05).The concentration of TF in plasma also sustainedly elevated in mice with 0,3,6,and 9 h recovery time after heat stress as compared to control group[(132.426±17.920)pg/ml,(119.400±10.267)pg/ml,(107.374±13.495)pg/ml,(163.767±22.810)pg/ml vs.(75.479±13.831)pg/ml,respectively,P<0.01].The expression levels of TF mRNA were higher in heat stress HUVECs with 6 h and 9 h recovery time than the control cells(1.905±0.354,2.564±0.297 vs.1.000±0.097,P<0.01).Secreted TF in the supernatant from HUVECs treated with heat stress and different recovery time also increased significantly[(36.309±4.101)pg/ml,(38.425±5.484)pg/ml,(41.655±4.380)pg/ml,(43.586±4.718)pg/ml vs.(14.996±0.254)pg/ml,P<0.01].Conclusion Heat stress increased early expression and secretion of TF in vascular endothelial cells.Vascular endothelial cells may be a main source of circulating TF in heat stroke.

ABSTRACT

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.

ABSTRACT

Objective:To investigate the efficacy and safety of semisupine-lithotomy position placement of Allium ureteral stent to treat ureteral stricture caused by pelvic tumours.Methods:The clinical data of 29 patients who received Allium ureteral stent(URS) placement for ureteral stricture in Sun Yat-sen Memorial Hospital, Sun Yat-sen University between April 2020 and March 2022 were retrospectively analyzed. There were 3 males and 26 females, with the median age of 56(54, 61) years old. All patients had a pathology confirmation of carcinoma before the treatment, including 26 patients with gynaecological tumours, two with urinary system tumours, and one with rectal carcinoma. A preoperative imaging examination confirmed the diagnosis of ureteral stricture. There were 15 patients with unilateral and 14 with bilateral stenosis, median stenosis length was 3.6(2.0, 4.9)cm. Preoperative median urine white blood cell count was 62(21, 354) U/L, median serum creatinine (SCR) was 170.0(85.5, 273.5) μmol/L, and renal pelvis separation was (32.98±6.64) mm. The median time of long-term indwelling double J (D-J)ureteral stent before surgery was 12.0 (6.5, 35.5) months. Seven patients had mild hydronephrosis, 18 had moderate hydronephrosis, and four had severe hydronephrosis. In all patients, Allium URS were placed in the way of the semisupine-lithotomy position (Galdakao-modified supine Valdivia position). Anterograde flexible ureteroscope was inserted into the percutaneous nephrostomy channel, and the retrogradel rigid ureteroscope were advanced simultaneously, looking for location of strictures. Allium URS were inserted retrogradely with transureteroscope when the two ureteroscope were connected. Perioperative conditions and postoperative follow-up for the last examination of SCR, renal pelvis width under ultrasound, and plain abdominal film (KUB). Allium URS patency and complications, hydronephrosis and renal function were evaluated.Results:A total of 61 Allium URS were successfully placed. Seven patients were placed in stages, and 18 patients were placed in series with multiple stents. The mean follow-up period was (12.1±5.8) months. At last follow-up, median SCR was 124.0(81.5, 193.0)μmol/L and renal pelvis separation was(14.96±5.18)mm, which were significantly decreased compared with preoperative(all P<0.01). There were 24 cases of hydronephrosis disappeared and 5 cases of mild hydronephrosis in the last follow-up. Postoperative follow-up, urinary tract infection occurred in 3 patients after operation, such as hematuria and fever within one week, and the symptoms were relieved after anti-infective and symptomatic treatment. One case had mild urine leakage, and 4 patients had occasional low back pain, which may be related to the activity. One case occurred stent displacement due to stent migration to the bladder after eight months, the URS was replaced and a D-J stent was inserted .The patency rate was 96.6%(28/29). Conclusions:Allium URS was placed in the semisupine-lithotomy position for treating pelvic tumour-induced ureteral stricture, with low incidence of complications, high patency and good curative effect.

ABSTRACT

We aimed to investigate the relationship of dietary zinc intake with new-onset hypertension among Chinese adults. A total of 12,177 participants who were free of hypertension at baseline from the China Health and Nutrition Survey were included. Dietary intake was assessed by three consecutive 24-h dietary recalls combined with a household food inventory. Participants with systolic blood pressure ≽ 140 mmHg or diastolic blood pressure ≽ 90 mmHg or diagnosed by a physician or under antihypertensive treatment during the follow-up were defined as having new-onset hypertension. During a median follow-up duration of 6.1 years, 4269 participants developed new-onset hypertension. Overall, the association between dietary zinc intake and new-onset hypertension followed a J-shape (P for non-linearity < 0.001). The risk of new-onset hypertension significantly decreased with the increment of dietary zinc intake (per mg/day: hazard ratio (HR) 0.93; 95% confidence interval (CI) 0.88-0.98) in participants with zinc intake < 10.9 mg/day, and increased with the increment of zinc intake (per mg/day: HR 1.14; 95% CI 1.11-1.16) in participants with zinc intake ≽ 10.9 mg/day. In conclusion, there was a J-shaped association between dietary zinc intake and new-onset hypertension in general Chinese adults, with an inflection point at about 10.9 mg/day.

ABSTRACT

Atopic dermatitis (AD) is a chronic, relapsing, inflammatory dermatosis with a variety of clinical manifestations and difficult to cure. Currently, many AD drug candidates have entered the research and development pipeline. In order to provide technical specifications for the clinical development of AD drugs, the Center for Drug Evaluation of National Medical Products Administration released the "Technical Guidelines for Clinical Trials of Drugs for AD Treatment" (Draft for Comments) in November 2022. Non-clinical pharmacodynamics evaluation is an important research before the drug enters clinical trials. Oxazolone (OXA)- and 2,4-dinitro-fluorobenzene (DNFB)-induced models are the most popular classical hapten-induced AD murine models, but variations of modeling are existing in the methods from different studies, including sensitization sites, haptens' dosages, the period of challenges, and the skin lesions severity evaluation as well. In this study, the investigation of OXA- and DNFB-induced AD murine models with various conditions of modeling was performed to compare the characteristics of hapten-induced AD murine models in the pathological process and severity according to the appearance of AD patients, and the guidance of pharmacodynamics evaluation of AD-therapeutic drugs in clinical trials as well, which may provide a proposal for AD treatment drug candidates in the non-clinical pharmacodynamics evaluation. All animal experiments were approved by the Animal Care & Welfare Committee of Institute of Materia Medica, Chinese Academy of Medical Sciences and Peking Union Medical College (approval No.: 00007782 and 00007784).

ABSTRACT

This study was designed to identify the pathogen causing soft rot of Pinellia ternata in Qianjiang of Hubei province and screen out the effective bactericides, so as to provide a theoretical basis for the control of soft rot of P. ternata. In this study, the pathogen was identified based on molecular biology and physiological biochemistry, followed by the detection of pathogenicity and pathogenicity spectrum via plant tissue inoculation in vitro and the indoor toxicity determination using the inhibition zone method to screen out bactericide with good antibacterial effects. The control effect of the bactericide against P. ternata soft rot was verified by the leave and tuber inoculation in vitro. The phylogenetic tree was constructed based on the 16 S rDNA, dnaX gene, and recA gene sequences, respectively, and the result showed that the pathogen belonged to the same branch as the type strain Dickeya fangzhongdai JS5. The physiological and biochemical tests showed that the pathogen was identical to D. fangzhongdai, which proved that the pathogen was D. fangzhongdai. The pathogenicity test indicated that the pathogen could obviously infect leaves at 24 h and tubers in 3 d. As revealed by the indoor toxicity test, 0.3% tetramycin, 5% allicin, and 80% ethylicin had good antibacterial activities, with EC_(50) values all less than 50 mg·L~(-1). Tests in tissues in vitro showed that 5% allicin exhibited the best control effect, followed by 0.3% tetramycin and 10% zhongshengmycin oligosaccharide, and their preventive effects were better than curative effects. Therefore, 5% allicin can be used as the preferred agent for the control of P. ternata soft rot, and 0.3% tetramycin and 10% zhongshengmycin oligosaccharide as the alternatives. This study has provided a certain theoretical basis for the control of P. ternata soft rot.

ABSTRACT

AIM: To analyze the infection characteristics and clinical treatment outcome of patients with fungal keratitis(FK)in Jingzhou area, so as to provide basis for clinical diagnosis and treatment of FK. METHODS: The data of 176 patients with FK diagnosed by etiology in Jingzhou Central Hospital from January 2015 to July 2020 were collected, and the epidemiological characteristics, identification results of fungal strains, drug sensitivity and clinical treatment outcome of the patients were analyzed. RESULTS:Among the 176 patients with FK, 118 were male and 58 were female, and the ratio of male to female is 2.03:1. The age of onset was the largest number of patients in 50-59 years old and 60-69 years old. The peak seasons of onset were April to June and October to December. Risk factors include trauma and possible history of trauma, ocular surface diseases, post ophthalmic surgery, wearing corneal contact lenses and long-term local drug use. The main pathogens were Fusarium(39.8%), aspergillus(30.7%), alternaria(15.9%)and candida(5.1%). The results of drug sensitivity showed that voriconazole and amphotericin B were sensitive, while the drug resistance rate of fluconazole was very high. There were 125 eyes improved or cured after conservative treatment, 12 eyes were injected into corneal stroma, 15 eyes were covered with conjunctival flap or amniotic membrane transplantation, and 21 eyes were treated with corneal transplantation. Enucleation of ocular contents was performed in 8 eyes, including 5 eyes with severe endophthalmitis after conjunctival flap covering. CONCLUSION:The incidence of FK in Jingzhou area is mostly middle-aged and elderly men, mostly caused by corneal trauma in the process of agricultural labor. The main pathogens were fusarium and aspergillus. It is very important to select reasonable antifungal drugs and treatment methods according to the drug sensitivity results.

ABSTRACT

Chemotherapy has been a major option in clinic treatment of malignant tumors. However, single chemotherapy faces some drawbacks, such as multidrug resistance, severe side effects, which hinder its clinic application in tumor treatment. Multifunctional nanoparticles loading with chemotherapeutic agent and photosensitizer could be a promising way to efficiently conduct tumor combination therapy. In the current study, a novel pH-sensitive and bubble-generating mesoporous silica-based drug delivery system (denoted as M(a)D@PI-PEG-RGD) was constructed. Ammonium bicarbonate (NH

ABSTRACT

Mammalian catechol-O-methyltransferases(COMT)are an important class of conjugative enzymes,which play a key role in the metabolism and inactivation of catechol neurotransmitters,catechol es-trogens and a wide range of endobiotics and xenobiotics that bear the catechol group.Currently,COMT inhibitors are used in combination with levodopa for the treatment of Parkinson's disease in clinical practice.The crucial role of COMT in human health has raised great interest in the development of more practical assays for highly selective and sensitive detection of COMT activity in real samples,as well as for rapid screening and characterization of COMT inhibitors as drug candidates.This review summarizes recent advances in analytical methodologies for sensing COMT activity and their applications.Several lists of biochemical assays for measuring COMT activity,including the probe substrates,along with their analytical conditions and kinetic parameters,are presented.Finally,the challenges and future perspec-tives in the field,such as visualization of COMT activity in vivo and in situ,are highlighted.Collectively,this review article overviews the practical assays for measuring COMT activities in complex biological samples,which will strongly facilitate the investigations on the relevance of COMT to human diseases and promote the discovery of COMT inhibitors via high-throughput screening.

ABSTRACT

Objective:To investigate the correlation between sarcopenia and post-stroke cognitive impairment(PSCI)in elderly patients with first-time acute minor ischemic stroke.Methods:This was a prospective study.Elderly patients over 60 years of age with first-time acute minor ischemic stroke admitted to the Department of Neurology of the General Hospital of Western Theater Command from October 2018 to June 2019 were continuously enrolled.Patients received the SARC-F score assessment within 24h after admission and were divided into two groups according to their SARC-F scores: the non-sarcopenia group(SARC-F score<4)and the sarcopenia group(SARC-F score≥4). Cognitive function was assessed by using the Mini-Mental State Examination(MMSE)within 24 h of admission and at 3-month follow-up.Results:A total of 211 patients were enrolled in this study, including 31 patients(31/211, 14.69%)in the sarcopenia group and 180 patients(180/211, 85.31%)in the non-sarcopenia group.The incidence of PSCI was higher in the sarcopenia group than in the non-sarcopenia group(83.87% or 26/31 vs.55.56% or 100/180, χ2=8.814, P=0.003). The total MMSE score, orientation, immediate memory, attention, calculation and language functions were lower in the sarcopenia group compared with non-sarcopenia group( P<0.05). Logistic regression analysis showed that sarcopenia was an independent risk factor for PSCI( OR=3.478, 95% CI: 1.039-11.642, P=0.043)in the elderly with first-time acute minor ischemic stroke. Conclusions:Sarcopenia is an independent risk factor for PSCI in elderly patients with first-time acute minor ischemic stroke.Sarcopenia assessment in the acute phase of stroke might help doctors to assess the risk of PSCI and reduce the incidence of PSCI in stroke patients.

ABSTRACT

Soil microorganisms are one of the important biological indictors of soil quality and can reflct the comprehensive ecological environment characteristics of the soil. The research of soil microbial diversity is the key to know the ecological functions and balance with soil. In this paper, high-throughput sequencing on PCR-amplified 16 S rRNA gene V3-V4 fragments was used to determine the bacterial diversity in rhizosphere soil of A. macrocephala under the treatment with BZJN1 or streptoprofen. The results showed that there were no significant differences of the bacteria in A. macrocephala rhizosphere soil of the streptoprofen treatment group and the biocontrol BZJN1 treatment group. All the soil bacteria was classified into 25 categories,67 classes, 108 orders, 167 families and 271 generas, except some unidentified bacteria. Proteobacteria(30.7%-34.8%) was the dominant phylum, of which Alphaproteobacteria(16.8%-18.5%) was the dominant subgroup. Compared with the control group, the relative abundance of multiple phylums bacteria in the rhizosphere soil of A. macrocephala was significantly changed in the streptoprofen treatment group and the biocontrol BZJN1 treatment group. In addition, RDA analysis showed that there was connection with different environmental factors and microbial communities. The abundance of the three genera in the rhizosphere soil of A. macrocephala was significantly positively correlated with Invertase, Urease and AP. PICRUSt function prediction results showed that BZNJ1 could enhance some bacterial functions and promote the plant growth. Biocontrol is a new type of green and safety control pest method. BZNJ1 significantly enhances some bacterial functions on the basis of effectively preventing root rot of A. macrocephala and promoting plant growth, and has no significant effect on the soil bacterial community structure. All the results can provide theoretical support for popularization of BZNJ1.

ABSTRACT

Coumarin is an important class of natural organic compounds, which widely exists in a variety of plants and microorganisms. Coumarins have many biological activities and wide clinical applications, such as anti-tumor, anti-HIV, anti-bacterial, anti-inflammatory, anti-oxidation, anti-coagulation, but they have obvious toxic effects in rodents. It was found that the toxicity of coumarins in different animals and organs was significantly different, and high dose oral administration was more likely to produce toxic reactions. Based on the research and analysis of domestic and foreign literatures in recent 60 years, this paper mainly summarized the hepatotoxicity and pulmonary toxicity induced by coumarins, and probed into their possible mechanisms. It was found that the toxicity of coumarins had metabolic differences and species differences. The liver of rats and lungs of mice were more susceptible to coumarins. Toxic reactions occurred mainly in the second metabolic pathway of coumarin metabolism in vivo. In order to put forward safety considerations and evaluate the impact of coumarin on human body, it was found that coumarin is unlikely to produce hepatotoxicity at normal exposure level. It was also suggested that species differences due to different metabolic patterns in model animals should be carefully considered when assessing coumarin toxicity, in order to provide reference for clinical research and rational use of coumarins and improve the rational use of coumarins.

ABSTRACT

OBJECTIVE@#To investigate the three-dimensional lip vermilion changes after extraction and non-extraction orthodontic treatment in female adult patients and explore the correlation between lip vermilion changes and incisor changes.@*METHODS@#Forty-seven young female adult patients were enrolled in this study (skeletal Class III patients were excluded), including 34 lip-protruding patients treated by extraction of four first premolars (18 patients requiring mini-implants for maximum anchorage control and 16 patients without mini-implants) and 13 patients requiring non-extraction treatment. Nine angles, seven distances, and the surface area of the lip vermilion were measured by using pre- and post-treatment three-dimensional facial scans. Linear and angular measurements of incisors were performed on lateral cephalograms.@*RESULTS@#There were no significant changes in the vermilion measurements in the non-extraction group. The vermilion angle, vermilion height, central bow angle, height/width ratio, and vermilion surface area decreased significantly after the orthodontic treatment in the extraction groups, but the upper/lower vermilion proportion remained unchanged. Significant correlations were found between the changes in incisor position and those in vermilion angles, vermilion height, and surface area.@*CONCLUSIONS@#Extraction of the four first premolars probably produced an aesthetic improvement in lip vermilion morphology. However, the upper/lower vermilion proportion remained unchanged. The variations in the vermilion were closely related to incisor changes, especially the upper incisor inclination changes.

ABSTRACT

Objective To understand the prevalence and disease distribution of migrants within the water source area of the Middle Route Project of South-to-North Water Diversion Project and analyze the influencing factors. Methods By multi-stage stratified cluster sampling method, 307 immigrants and 676 immigrants were selected from Danjiangkou reservoir area, Shiyan city, Hubei Province. Results The prevalence of chronic diseases among in-migration was 51.8%. The prevalence rates of the top five chronic diseases were waist and leg pain, hypertension, gastritis, heart disease and diabetes. The prevalence of chronic diseases among out-migration was 65.1%. The prevalence rates of the top five chronic diseases were waist and leg pain, hypertension, gastritis, heart disease and bronchitis. The rate of chronic disease, the rate of two weeks and the rate of two weeks' visit were higher than that of emigration(all P<0.05). The results of multivariate analysis showed that the factors influencing the chronic diseases of immigrants were 60 years old (OR=59.928,P<0.001), unsatisfied family income (OR=0.377, P=0.002) and poor economic status (OR=0.517, P=0.028). The factors influencing the chronic diseases of immigrants were 60 years old (OR=26.190, P<0.001), smoking (OR=1.856,P=0.004), unsatisfactory family income (OR=0.598,P=0.029) and poor economic status (OR=0.460,P<0.001). Conclusions The prevalence of migrants within a high level is at a high level. Actually raising the income of immigrants is conducive to improving the health condition of immigrants.

BACKGROUND@#Despite a growing population of patients starting hemodialysis in China, little is known about markers of mineral bone disease (MBD) and their management. We present data on prevalence and correlates of hypocalcemia, hyperphosphatemia, and secondary hyperparathyroidism from the China Dialysis Outcomes and Practice Patterns Study (DOPPS), with evaluation of whether these laboratory markers triggered changes in management.@*METHODS@#We compared the frequency of measurement and prevalence of poor control of MBD markers in China DOPPS with other DOPPS regions. We also used generalized estimating equations to assess correlates of MBD markers, and separate models to assess predictors of vitamin D and phosphate binder prescriptions in the China DOPPS.@*RESULTS@#Severe hyperphosphatemia (>7 mg/dL) and secondary hyperparathyroidism (>600 pg/mL) were common (27% and 21% prevalence, respectively); both were measured infrequently (14.9% and 3.2% of patients received monthly measurements in China). Frequency of dialysis sessions was positively associated with hyperphosphatemia; presence of residual kidney function was negatively associated with both hyperphosphatemia and secondary hyperparathyroidism. Laboratory measures indicating poor control of MBD were not associated with subsequent prescription of active vitamin D or phosphate binder.@*CONCLUSIONS@#There are substantial opportunities for improvement and standardization of MBD management in China. Development of country-specific guidelines may yield realistic targets and standardization of medication use accounting for availability and cost.

ABSTRACT

Objective To stage orthotopicilealneobladder function and construct the corresponding training mode according to the results of urodynamic examination.Methods 38 patients with bladder cancer underwent radical resection+orthotopicilealneobladder surgery between August 2013 and August 2017,and the urodynamic examination results of 3 months,6 months,1 year,2 years,3 years of were retrospectively analyzed.The bladder function of the patients with orthotopicilealneobladder was staged according to urodynamic examination,and the bladder function training mode was formed.Results As the follow-up time increased after surgery,day/night urine control increased,the maximum urine flow rate,the average urine flow rate increased,urination time shortening,bladder capacity increased,bladder basic pressure decreased,bladder filling state pressure,bladder compliance increased,micturition maximal bladder pressure,maximum abdominal pressure and maximum detrusor pressure increased,and all the indexes tended to be stable after 1 year.Bladder function training orthotopicilealneobladder is divided into four periods,respectively are Hospitalization period,recovery period(3 months after surgery),rehabilitation period(3 months to 1 year after surgery),stable period(1 year after surgery),and formed different stages of orthotopicilealneobladder bladder function training content.The focus nursing of each stage is that early period-drainage tube care,recovery period-incontinence care,rehabilitation period-urinary training,stable period-complications handling.Conclusions According to the results of urodynamic examination,it is possible to propose a targeted,scientific and practical bladder function training model for the orthotopicilealneobladder.
