RESUMO
@#Objective To investigated the effect of tripterygium glycosides(TG)on dextran sodium sulfate(DSS)-induced colonic mucosal damage in ulcerative colitis(UC)mice and its regulatory mechanism.Methods Forty C57BL/6J mice were randomly divided into a normal group,a model group,and a tretinoin low,medium,and high dose group(administered at concentrations of 9.00mg/kg,27.03mg/kg,and 81.09mg/kg,respectively).The mice in the normal group were free to drink distilled water,and the rest of the mice drank 5%DSS to induce UC modeling.After modeling,mice in the model group were given 0.4ml of saline by gavage daily,and the rest of the mice in the treatment group were given the corresponding dose of TG for gavage intervention.The mass and disease activity index of the mice in each group were compared,and the pathological and histological damage of the colon was observed.Tumor necrosis factor-α(TNF-α),malondialdehyde(MDA),and superoxide dismutase(SOD)levels were measured using the corresponding kits.Western blot Detection of Nur77,tumor necrosis factor receptor-associated factor 2(Traf2),nucleoporin 62(P62),autophagy protein-microtubule associated protein1 light chain 3(LC3)molecular expression.Results Compared with the blank group,the body weight,colon length,SOD,Nur77,Traf2,and LC3Ⅱ/LC3Ⅰ levels of mice in the model group were significantly decreased(P<0.05),and the DAI level,colon pathology score,TNF-α,MDA level,and P62 of the mice were significantly increased(P<0.05).Compared with mice in the UC model group,mice in the low,medium and high dose groups of tretinoin polyphenols showed significant increases in body weight,colon length,SOD,Nur77,Traf2,LC3Ⅱ/LC3Ⅰlevels(P<0.05),and mice with DAI scores,TNF-α,MDA levels in the colon,and P62 levels were significantly decreased(P<0.05).Mice in the medium and high dose groups of tretinoin polyphenols pathological scores were significantly reduced(P<0.05).Conclusion TG is able to treat ulcerative colitis through Nur77-Traf2-P62 signaling pathway.
RESUMO
Objective To observe the distribution and characteristics of lymphatic vessels in normal and injured mouse spinal cord,and to determine if lymphatic vessels participate in the repair of spinal cord injury.Methods Thirty-nine adult male KM mice were divided randomly into a normal group(n=6)and an injured group(n=33).Mice in the injured group were further divided randomly into mice examined on postoperative days 1,3,5,7,and 14.Three mice in the injury group died after acupuncture injury,and the sample was subsequently supplemented randomly.Spinal cord damage was induced in the injured group by acupuncture,while mice in the normal group had no spinal cord damage.The distribution of lymphatic endothelial cells(LECs)in the spinal cord was detected by immunohistochemistry,and expression levels of the lymphatic endothelial cell markers prospero-related homobox-1(prox-1),lymphatic vessel endothelial cell hyaluronic acid receptor-1(lyve-1),and flat foot protein(podoplanin),and the vascular endothelial cell marker CD34 were observed in the spinal cords in normal and acupuncture-injured mice.Spinal cord samples were examined by immunofluorescence staining,and the source of new LECs was explored by observing the co-expression of lyve-1/prox-1,lyve-1/podoplanin,and CD34/prox-1.Results Lymphangioid structures were present in the spinal cord in normal mice and were distributed in segments,laterally between the white matter and gray matter.Nascent lymphangioid-like structures appeared in the spinal cord at the site of acupuncture injury,and prox-1,podoplanin,lyve-1,and CD34 were expressed simultaneously;however,these nascent lymphangioid-like structures disappeared after scarring during spinal cord injury.Conclusions Segmental,transversely distributed lymphangioid-like structures are present in the spinal cord in normal adult mice,and neonatal lymphangioid-like structures are involved in the reconstruction of spinal cord injury.These nascent LECs may originate from the surrounding existing lymphatic vessels or from vascular endothelial cells.
RESUMO
ObjectiveTo collect and analyze the properties and application characteristics of external use of roots and rhizomes of Chinese herbal medicines in the Chinese Materia Medica(《中华本草》) to provide data references for the research on clinical external use of Chinese medicine, in order to provide data reference for clinical external use of traditional Chinese medicine(TCM). MethodThe Chinese herbal medicines included in the Chinese Materia Medica were systematically screened. The inclusion criterion was the explicit mention of terms like "root", "rhizome", "root bark", "tuber", "tuberous root", etc. under the "Source" in the Chinese Materia Medica. Information on properties, flavors, meridian tropism, medicinal parts, fresh use, toxicity, efficacies and indications, and dosage of roots and rhizomes of Chinese herbal medicines was collected. The information was then entered into an Excel spreadsheet for statistical analysis. ResultThe Chinese Materia Medica records 2 662 roots and rhizomes of Chinese herbal medicines, of which 1 653 are suitable for external use. The predominant properties and flavors are cool, cold, bitter, pungent, and sweet. These Chinese herbal medicines mainly act on the liver, lung, and spleen meridians. The primary medicinal parts used include root, rhizome, and root bark. More than half of the roots and rhizomes of Chinese herbal medicines can be used in their fresh form. The main efficacies include clearing heat, removing toxins, resolving stasis, dispersing accumulation, resolving blood stasis and stopping bleeding, reducing swelling and alleviating pain, dispelling dampness and relieving pain. The main indications are skin sores, traumatic injuries, and rheumatic diseases. Common external application methods include poultice, decoction for washing, and applying powdered form. Most of these Chinese herbal medicines lack specific dosage guidelines for external use, with an emphasis on using an appropriate amount. ConclusionThe Chinese Materia Medica contains a wide range of roots and rhizomes of Chinese herbal medicines suitable for external use, with definite therapeutic effects, providing a broad perspective for the application of Chinese medicine externally. However, there are still problems such as unclear dosages and limited research. Further studies are necessary to better utilize the advantages of the external use of Chinese medicine.
RESUMO
Objective To investigate the organic components in cefmetazole sodium butyl rubber clousures for injection and their migration into drugs,and to evaluate the compatibility of pharmaceutical butyl rubber clousures with cefmetazole sodium.Methods The structures of volatile components in butyl rubber clousures of cefmetzole sodium for injection and those migrated into drugs were identified by GC/MS SCAN mode and National Institute of Standard and Technology(NIST)spectrum library.An HPLC method was established to quantitatively analyse the antioxidants and vulcanizing agents transferred from butyl rubber clousures into drugs.Results Organic compounds such as antioxidant BHT and silicone oil were identified by GC/MS.The HPLC was used to determine the peak area of antioxidant(168,264,330,1 076,1 010)and vulcanizing agent in the range of 0.5-100 μg·mL-1 with good linear relationship with the peak area.The average recoveries(low,medium,and high)of antioxidant and vulcanizing agents ranged from 90.0%to 110.0%,and the corresponding RSD were all less than 2%(n=9).It was found that the antioxidant BHT and silicone oil in cefmetazole sodium butyl rubber clousures for injection would migrate into the drug and affect the clarity of the solution.Conclusion GC-MS/HPLC method can be used as an effective method for quality control of packing materials(butyl rubber clousures)and drug compatibility studies,so as to ensure the safety of drug use by the public.
RESUMO
Background Research on non-target organ damage of biological pesticides has attracted much attention. Rotenone exposure may be far beyond the occupational environment, and the exposureduring pregnancy may be increased through bioaccumulation, fruit or vegetable residues, and other forms of oral intake. At present, the effects of rotenone on placental development and its mechanism are still unknown. Objective To investigate the developmental damage of rat placenta and evaluate the expression levels of glycogen synthase kinase (GSK-3β) and beta catenin (β-catenin) followed by rotenone exposure through the placental barrier during pregnancy, as well as to propose possible associated mechanisms. Methods Eighteen sexually mature SD female infertile rats without specific pathogens were selected and divided into three groups: blank control group (0.9% saline), corn oil group, and rotenone group (corn oil + 2 mg·kg−1 rotenone) by random number method, six female animals in each group. Another six male rats were selected and mated to the female rats at night with a female to male ratio of 3:1 per cage. Pregnant rats were given 0.9% saline, corn oil, and 2 mg·kg−1 rotenone preparation by isovolumetric gavage once daily for the entire gestation period (19 d), and their conditions were observed after the last dose. The pregnant rats were anesthetized, and the size of the placenta and blood perfusion were detected by ultrasound the next day of the last dose of rotenone. Then, 3 pregnant rats in each group were sacrificed immediately and the placenta and umbilical cord tissues were dissected. The remaining 9 pregnant rats gave birth naturally, and the fetuses were observed for developmental evaluation and weighed. The histopathological changes of umbilical cord and placenta were observed by hematoxylin-eosin staining. The reactive oxygen species levels of placenta tissues were detected by flow cytometry. The Ca2+-ATPase activity of placenta tissues was detected by colorimetric method. The localization and levels of GSK-3β and β-catenin expression of placenta were detected by immunohistochemistry. The p-GSK-3β/GSK-3β and p-β-catenin/β-catenin protein expression in placental tissues were measured by Western blotting. Results No injury or death was recorded during the pregnant rats receiving rotennon administration. Adverse pregnancy outcomes such as fetal absorption and postpartum stillbirth were found in the rotenone group, and the weight of the fetal mice decreased (P<0.05). The B-ultrasound showed disc-shaped placenta with a thick middle and thin edge, smooth fetal surface, rough maternal surface, visible placental lobules, granular echotexture of the placenta with comma-like echogenic densities, and chorionic plate showing deep indentations, no calcification, degeneration, or necrosis in each group. Compared with the corn oil group, the fetal surface diameter of the placenta was reduced in the rotenone group (P<0.05). The Doppler color ultrasound showed that interplacental blood flow was reduced in the rotenone group, while interplacental blood flow was abundant in the blank control and the corn oil groups. The hematoxylin-eosin staining results showed that smooth muscle cells in the umbilical cord tissues of rats were loosely arranged, with fuzzy nuclei and inflammatory infiltration in the rotenone group. The placental trophoblast cells were small in size, disorderly arranged with nuclear fragmentation and cytoplasm turbidity. The tissue reactive oxygen species level in the rotenone group was higher than those in the other two groups (P<0.05). The Ca2+-ATPase activity of placental tissues was reduced in the rotenone group (P<0.05). The immunofluorescence low-magnification observation showed that GSK-3β and β-catenin were expressed in placental tissue, weak fluorescence expression in the decidua basalis, strong fluorescence expression in the labyrinthine layer structure. The labyrinthine layer under high magnification showed that compared with the blank control group and the corn oil group, the brightness of β-catenin fluorescence expression in the rotenone group decreased (P<0.05), and the brightness of GSK-3β expression increased (P<0.05). The Western blotting results showed that the expression of β-catenin and p-GSK-3β proteins decreased (P<0.01), and the expression of GSK-3β protein increased (P<0.01) in the rotenone group. No significant expression of p-β-catenin protein was detected in the placenta tissue of each group. Conclusion Rotenone exposure during pregnancy induces placental hypoperfusion, growth retardation, and oxidative stress in rats, as well as down-regulation of β-catenin and p-GSK-3β protein expression, and up-regulation of GSK-3β protein expression, which may further lead to abnormal pregnancy and fetal restricted growth.
RESUMO
Closed-loop hospital management can effectivly cope with the COVID-19 pandemic. In order to ensure the continuity of treatments for hemodialysis patients under closed-loop management and minimize possible medical and infection risks, Huashan Hospital affiliated to Fudan University and 9 hospitals in Shanghai established a hemodialysis alliance in January 2021.The alliance optimized hemodialysis resources within the region through overall planning by preparing sites, materials and personnel shifts in advance, and establishing management systems and work processes to ensure that patients could be quickly and orderly diverted to other blood dialysis centers for uninterrupted high-quality hemodialysis services, in case that some hemodialysis centers in the alliance under closed-loop management.From November 2021 to April 2022, 317 of 1 459 hemodialysis patients in the alliance were diverted to other centers for treatment, accumulating 1 215 times/cases of treatments without obvious adverse reactions. The practice could provide a reference for medical institutions to quickly establish mutual support mode under major public health events.
RESUMO
: To explore the potential associations between perceived stress and health-promoting behaviors based on the theoretical schema of the middle-range theory of adaptation to chronic illness. From January to May 2021, a convenience sampling method was used to recruit 230 young and middle-aged patients with metabolic syndrome who underwent physical examination in the inpatient center of Sir Run Run Shaw Hospital, Zhejiang University School of Medicine. The Health-Promoting Health Profile-Ⅱ, Chinese Perceived Stress Scale, Coping and Adaptation Processing Scale-Short Form, and Multi-dimensional Scale of Perceived Social Support were used in the cross-sectional study. The chain mediation effect procedure and bootstrap sampling test were used to examine the mediating role of adaptability and social support between perceived stress and health-promoting behaviors. The mean score of health-promoting behaviors was 100.0±14.6, the mean score of perceived stress was 22.0± 6.9, the mean score of adaptability was 47.0±6.1, and the mean score of social support was 63.8±10.8. Perceived stress had a negative impact on patients' health-promoting behaviors (=-0.309, <0.05). The adaptability (effect size= -0.112, 95%:-0.199~-0.038) and social support (effect size= -0.032, 95%:-0.083~played a mediating role and a chain mediating role in the process of perceived stress influencing patients' health-promoting behaviors (effect size= -0.045, 95%:-0.093~-0.020). Adaptability and social support play an intermediary role between perceived stress and health-promoting behaviors in young and middle-aged patients with metabolic syndrome. Healthcare professionals can motivate patients to develop healthy behaviors by developing intervention strategies on adaptability and social support.

RESUMO
Objective:To evaluate the relationship between preoperative malnutrition and postoperative pulmonary complications (PPCs) in elderly patients undergoing thoracoscopic and laparoscopic radical esophagectomy.Methods:The elderly patients who underwent elective thoracoscopic and laparoscopic radical esophagectomy in the Affiliated Hospital of Jiangnan University were enrolled.The general clinical data and nutritional status, Assess Respiratory Risk in Surgical Patients in Catalonia (ARISCAT) score, tumor pathological stage and operation-related variables based on the Gobal Leader Initiative on Malnutrition criteria were recorded.The patients were divided into 2 groups according to whether PPCs occurred during hospitalization, and the differences between the variables were compared.Logistic regression analysis was used to identify the risk factors for PPCs in elderly patients undergoing thoracoscopic and laparoscopic radical esophagectomy.The accuracy of the ARISCAT score and ARISCAT score combined with malnutrition in predicting the occurrence of PPCs was evaluated by receiver operating characteristic curve.Results:A total of 256 elderly patients undergoing thoracoscopic and laparoscopic radical esophagectomy were included, and the incidence of PPCs was 23.8%.There were no significant differences between patients with and without PPCs in FEV 1/FVC, age, American Society of Anesthesiologists physical status, chronic obstructive pulmonary disease ratio, malnutrition ratio and ratio of patients with high ARISCAT score ( P<0.05). The results of logistic regression analysis showed that increasing age, chronic obstructive pulmonary disease, malnutrition and high ARISCAT score were independent risk factors for PPCs.The area under the receiver operating characteristic curve of ARISCAT score and malnutrition combined with ARISCAT score in predicting the occurrence of PPCs was 0.722 and 0.777, respectively, and the difference was statistically significant ( P<0.05). Conclusions:Preoperative malnutrition is an independent risk factor for the occurrence of PPCs in elderly patients undergoing thoracoscopic and laparoscopic radical esophagectomy, which is helpful in improving the accuracy of ARISCAT score in predicting the occurrence of PPCs.
RESUMO
To analyze the mediating role of anxiety and depression in perceived social support and fatigue in ICU patients′ families, and to provide a theoretical evidence for alleviating their fatigue status. A total of 223 family members of ICU patients who received treatment at the Affiliated Hospital of Jiangnan University from October 2020 to April 2021 were selected as the study subjects. The general data questionnaire, perceived social support scale (PSSS), generalized anxiety disorder scale (GAD-7), patient health questionnaire (PHQ-9) and fatigue assessment instrument (FAI) were used to conduct a survey. Among 223 family members of ICU patients, 155(69.51%) had fatigue problems. There were statistically significant differences in total fatigue scores of ICU patients′ family members in terms of gender, age, education level, relationship with patients, residence, payment method and per capita monthly income ( P<0.05). Anxiety, depression and fatigue were negatively correlated with perceived social support ( r are -0.353, -0.276 and -0.416, respectively, all P<0.01). Depression and fatigue were positively correlated with anxiety ( r are 0.808 and 0.703, respectively, all P<0.01), and fatigue was also positively correlated with depression ( r= 0.665, P<0.01). Anxiety and depression had a partial mediating effect on perceived social support and fatigue, and the total indirect effect size was 52.64%. Comprehensive intervention on the level of social support, anxiety and depression is helpful to improve the fatigue status of ICU patients′ family members.
RESUMO
Objective:To monitor and investigate the long-term growth trend and nutritional status of very preterm infants (VPIs, born at gestational age between [28~31 +] weeks) with extrauterine growth restriction (EUGR) from birth to preschool period. Methods:VPIs who met with the following criteria were enrolled: infants born in Huai'an Maternity and Child Heath Care Hospital from January 1 to December 31, 2015; infants admitted to the Neonatal Medical Center and discharged alive; infants who received multi-disciplinary treatment in Child Care Division from discharge to preschool period. All of the VPIs were divided into the EUGR group and the non-EUGR group according to whether the weight at hospital discharge was below the 10 th percentile for corrected age in body weight. The weight for age Z score (WAZ), height for age Z score (HAZ), and head circumference for age Z score (HCZ) were calculated at each specified time point (at 40 weeks of age; at 1, 2, 3, 4, 5, 6 and 24 months of corrected age; and at 48 months of age). The growth trend and the nutritional status at 48 months of age were compared between the two groups. Results:1. A total of 53 VPIs were enrolled, among whom 35 cases were boys and 20 cases were with EUGR. The differences in the gestational age, birth weight, incidence of very low birth weight infants, neonatal respiratory distress syndrome (NRDS) and bronchopulmonary dysplasia (BPD) were all statistically significant between the EUGR group and the control group ( x 2= 2.306, 3.543, 10.852, 9.515, 0.001, respectively; all P<0.05). 2. The WAZ and HAZ of the EUGR group were lower at each time point. The WAZ at 40 weeks of age and the HAZ at 3 months of corrected age were significantly different between the two groups. From 40 weeks of age to 2 months of corrected age and from 6 months to 24 months of corrected age, the WAZ, HAZ and HCZ in both groups showed an increasing trend. However, the WAZ in the EUGR group and the WAZ, HAZ and HCZ in the non-EUGR group showed a declining trend from 24 months of corrected age to 48 months of age. 3. There was no significant differences in growth restriction incidence at each time point between the EUGR group and the control group. 4. The nutritional status showed no significant difference between the two groups, either ( P>0.05). Conclusions:Low gestational age, low birth weight, NRDS and BPD are the risk factors of EUGR. The growth trend of the EUGR VPIs shows an overall upward trend from hospital discharge to 24 months of corrected age but declined thereafter, while the nutritional status is good at 48 months of age. Thus, in addition to the integrated management, continuous monitoring of long-term growth and nutrient input after 24 months of age is required for VPIs.
RESUMO
Objective:To evaluate the relationship between preoperative frailty and postoperative pulmonary complications (PPCs) in elderly patients undergoing thoracoscopic lobectomy.Methods:The elderly patients with non-small cell lung cancer who underwent thoracoscopic lobectomy in the Affiliated Hospital of Jiangnan University were collected.The general data, frailty status, parameters of blood and operation-related parameters were recorded.The patients were divided into PPC group and non-PPC group according to whether PPCs occurred during hospitalization, and the differences between the parameters were compared.Logistic regression analysis was used to analyze the independent risk factors for PPCs.Stratification analysis and interaction test were used to further analyze the relationship between frailty and PPCs.Results:A total of 298 elderly patients with non-small cell lung cancer undergoing thoracoscopic lobectomy were included in this study, and the incidence of PPCs was 22.8%.Compared with non-PPC group, the albumin and FEV 1/FVC were decreased, and age, blood creatinine, ratio of diabetes mellitus, ratio of chronic obstructive pulmonary disease (COPD) and rate of preoperative frailty were significantly increased in PPC group ( P<0.05). The results of logistic regression analysis showed that COPD and preoperative frailty were independent risk factors for PPCs.After adjusting all the risk variables, the frail patients had a 171% increased risk of PPCs compared with non-frail patients ( OR value=2.71, 95%CI: 1.18-4.73, P<0.05). The results of subgroup analysis showed that body mass index and operation time had effect modification on the association between frailty and PPCs (interaction P<0.05). Conclusion:COPD and preoperative frailty are independent risk factors for PPCs in elderly patients undergoing thoracoscopic lobectomy, and the frail patients with obesity or long operation time are at higher risk of PPCs.

The included studies were screened and evaluated with modified Jadad scale. Meta-analysis was performed by using Rev Man 5.3 software. RESULTS :A total of 10 RCTs were included ,involving 1 123 patients. Meta-analysis results showed that compared with atorvastatin calcium group ,nitcodil combined with atorvastatin calcium group significantly increased angina response rate [OR =3.44,95%CI(2.35,5.04),P<0.001],the rate of electrocardiogram improvement [OR =4.93,95%CI(2.88, 8.43),P<0.001],and significantly reduced MMP- 9 level [SMD =-4.21,95%CI(-4.63,-3.80),P<0.001],incidence of recurrent angina pectoris [OR =0.30,95%CI(0.12,0.71),P=0.006],myocardial infarction rate [OR =0.27,95%CI(0.08,0.89), P=0.03],the incidence of adverse cardiovascular events [OR =0.34,95% CI(0.21,0.55),P<0.001]. CONCLUSIONS : Nicorandil combined with atorvastatin calcium shows better efficacy in the treatment of unstable angina pectoris in terms of effective rate of angina pectoris ,improvement rate of cardiogram ,MMP-9 level,incidence of recurrent angina pectoris and the incidence of myocardial infarction ,and has better safety in the incidence of adverse cardiovascular events. Due to the limitation of included studies ,it remains to be verified by RCT with large sample,multi-center and high quality.
RESUMO
Objective: To observe CT manifestations of bladder neuroendocrine tumors (NET) with different pathological grades. Methods: Clinical, pathological and CT data of 17 patients with bladder NET confirmed with pathology were retrospectively analyzed. According to the WHO 2010 pathological classification standard, all tumors were classified and then divided into low-grade group (G1 and G2) and high-grade group (G3). The differences of clinical and CT findings were compared between 2 groups. Results: Among 17 cases of bladder NET, 6 were G1, 2 were G2 and 9 were G3 tumors. There were 8 cases in low-grade group and 9 cases in high-grade group, respectively. Statistically differences of patients gender and ages (t=-3.43) (P=0.03, 0.04), also of the maximum tumor size, cystic change or necrosis, peripheral invasion and metastasis were found between 2 groups (all P<0.05). The arterial absolute enhancement degree of tumors in low-grade group ([58.62±12.45]HU) was higher than that in high-grade group ([31.88±8.86] HU) (t=5.15, P<0.01). Conclusion: CT manifestations of bladder NET with different pathological grades had certain characteristics, being helpful to diagnosis combined with clinical data.
