ABSTRACT

Objective To comprehensively analyze the reported preparation methods for animal models of perimenopausal syndrome (PS), to compare the advantages and disadvantages of various preparation elements and detection indexes, so as to provide useful references for the optimization of the relevant animal models as well as the standardization of their application in the efficacy evaluation of new drugs.MethodsIn this paper, literature research methods were applied using "perimenopausal syndrome" as the subject term. The publication period of the literature was limited to January 2016 to February 2023. Relevant literature on the preparation of PS animal models was retrieved from databases such as China National Knowledge Infrastructure, Wanfang database, and PubMed. After screening the experimental literature that met the inclusion and exclusion criteria, detailed information on experimental animal strains, modeling methods, duration of drug administration, positive drugs, detection indexes and other relevant information were collected. After the above information was standardized, the PS animal model database was established using Excel 2010 software. The model preparation elements and evaluation indexes were summarized systematically, and the statistical results were processed and analyzed using Excel 2010 software.Results A total of 247 articles were screened. SD rats (164 times, 65.86%) and Wistar rats (35 times, 14.06%) were often used to prepare PS animal models. Bilateral ovariectomy (139 times, 53.87%) and natural aging (43 times, 16.80%) were chosen as modeling methods. The ages of rats used for modeling ranged from 7 weeks to 18 months, with 3-month-old rats (22 times, 21.78%) being the most common. The detection indexes were comprehensively evaluated from multiple perspectives, including serum biochemistry, vaginal exfoliated cell smear, histomorphology, general observation, behavioral observation, and organ tissue protein immunoblotting. Western medical evaluation indexes were commonly used to test the successful preparation of models, with vaginal exfoliated cell smears being the most frequently used method (125 times, 85.04%). A model was considered successfully prepared when estrous cycle disorder or irregularity was observed. Some literature also determined modeling success by detecting a significant decrease in serum estradiol levels (5 times, 3.04%). Traditional Chinese medicine (TCM) syndrome evaluation often used a combination of Chinese and Western medical evaluation indexes for comprehensive evaluation, with researchers determining the TCM syndrome through vaginal exfoliated cell smears supplemented by general observation (3 times, 2.04%).Conclusion There are many methods for preparing PS animal models, but there are still significant differences in the selection of animal species, age, criteria for successful modeling, and TCM syndrome evaluation in the related literature.

ABSTRACT

Purpose@#To identify the predictors of infectious disease-specific health literacy (IDSHL), and establish an easy-to-apply nomogram to predict the IDSHL of older adults. @*Methods@#This cross-sectional study included 380 older adults who completed the IDSHL, self-rated health, socio-demographic and other questionnaires. Logistic regression was used to identify the IDSHL predictors. Nomogram was used to construct a predictive model. @*Results@#Up to 70.1% of older adults had limited IDSHL. Age, education, place of residence, self-rated health, and Internet access were the important influencing factors of IDSHL. The established nomogram model showed high accuracy (receiver operating characteristic curve: 0.848). @*Conclusions@#The IDSHL of Chinese older adults was significantly deficient. The constructed nomogram is an intuitive tool for IDSHL prediction that can not only contribute toward rapid screening of high-risk older adults with limited IDSHL but also provide guidance for healthcare providers to develop prevention strategies for infectious diseases.

ABSTRACT

ObjectiveTo investigate the general situation of defect of vertebral column among primary and middle school students in Minhang District of Shanghai and analyze the related factors, to provide a scientific basis for prevention and treatment. MethodsFrom September to October 2022, a total of 5 715 students were selected from two primary schools, two middle schools, and two high schools in Minhang District for physical examinations and screening for defect of vertebral column. ResultsTotally 219 students had defect of vertebral column, accounting for 3.83% of the sampled population. Anteroposterior spinal abnormalities were found in 4 individuals, accounting for 0.07%, and 218 students had scoliosis, accounting for 3.81%. The detection rate of defect of vertebral column was higher in girls (6.27%) than that in boys (1.51%), and higher in high school students (10.74%) than in primary school students (1.31%) and middle school students (10.97%). Students who are mildly underweight (5.95%) and who are moderately to severely underweight (7.46%) had a higher detection rate of defect of vertebral column than those with normal weight (4.54%), overweight (2.83%), and obesity (1.60%). The detection rate among students with poor vision (4.32%) was significantly higher than those with normal vision (2.24%), with all differences statistically significant (all P<0.05). ConclusionThe positive rate of defect of vertebral column in primary and middle school students in Minhang District, Shanghai is nearly 4%, with most cases being scoliosis. Factors such as being female, increasing age, being underweight, and poor vision are associated with a higher probability of detecting defect of vertebral column.

ABSTRACT

Pulpitis, periodontitis, jaw bone defect, and temporomandibular joint damage are common oral and maxillofacial diseases in clinic, but traditional treatments are unable to restore the structure and function of the injured tissues. Due to their good biocompatibility, biodegradability, antioxidant effect, anti-inflammatory activity, and broad-spectrum antimicrobial property, chitosan-based hydrogels have shown broad applicable prospects in the field of oral tissue engineering. Quaternization, carboxymethylation, and sulfonation are common chemical modification strategies to improve the physicochemical properties and biological functions of chitosan-based hydrogels, while the construction of hydrogel composite systems via carrying porous microspheres or nanoparticles can achieve local sequential delivery of diverse drugs or bioactive factors, laying a solid foundation for the well-organized regeneration of defective tissues. Chemical cross-linking is commonly employed to fabricate irreversible permanent chitosan gels, and physical cross-linking enables the formation of reversible gel networks. Representing suitable scaffold biomaterials, several chitosan-based hydrogels transplanted with stem cells, growth factors or exosomes have been used in an attempt to regenerate oral soft and hard tissues. Currently, remarkable advances have been made in promoting the regeneration of pulp-dentin complex, cementum-periodontium-alveolar bone complex, jaw bone, and cartilage. However, the clinical translation of chitosan-based hydrogels still encounters multiple challenges. In future, more in vivo clinical exploration under the conditions of oral complex microenvironments should be performed, and the combined application of chitosan-based hydrogels and a variety of bioactive factors, biomaterials, and state-of-the-art biotechnologies can be pursued in order to realize multifaceted complete regeneration of oral tissue.

ABSTRACT

Objective:To explore the relationship between serum retinol binding protein(RBP)and metabolic-associated fatty liver disease(MAFLD)in elderly patients with type 2 diabetes mellitus(T2DM)and possible underlying metabolic mechanisms.Methods:A total of 3384 elderly T2DM patients hospitalized and with complete clinical records at the Department of Endocrinology and Metabolism, Sixth People's Hospital Affiliated to Shanghai Jiao Tong University between January 2003 and December 2012 were recruited in this retrospective study.Patients were divided into four groups according to the quartiles of serum RBP levels: the first quartile of serum RBP levels(<35 mg/L, 844 cases), the second quartile of serum RBP levels(35 mg/L≤ RBP ≤41 mg/L, 773 cases), the third quartile of serum RBP levels(42 mg/L≤ RBP ≤51 mg/L, 902 cases), and the fourth quartile of serum RBP levels(RBP>51 mg/L, 865 cases). Clinical data and laboratory test results were collected.Differences in the prevalence of MAFLD were compared between the four groups.The association between RBP and MAFLD was analyzed via binary logistic regression.Results:After adjusting for age and sex, the proportion of obesity( χ2=15.222, P<0.01), the percentage using lipid-lowering drugs( χ2=88.552, P<0.01), systolic blood pressure( F=12.002, P<0.01), diastolic blood pressure( F=6.872, P<0.01), waist circumference( F=9.563, P<0.01), waist-hip ratio( F=7.972, P<0.01), body mass index( F=9.057, P<0.01), serum creatinine( χ2=185.445, P<0.01), serum uric acid( χ2=314.691, P<0.01), 24-hour urinary albumin( χ2=91.012, P<0.01), alanine aminotransferase( χ2=17.049, P=0.003), γ-glutamyl transpeptidase( χ2=50.514, P<0.01), total cholesterol( F=45.669, P<0.01), triglycerides( χ2=361.269, P<0.01), low-density lipoprotein( F=8.772, P<0.01), fasting C-peptide( χ2=165.756, P<0.01), 2h postprandial C-peptide( χ2=120.690, P<0.01), and the homeostasis model assessment of insulin resistance(HOMA2-IR)( χ2=148.884, P<0.01)in elderly patients with T2DM all showed a clear upward trend.The prevalence of MAFLD also gradually increased across the quartiles of serum RBP levels[26.5%(224/844), 30.1%(233/773), 36.6%(330/902), and 41.8%(362/865)], respectively( χ2=52.526, P<0.01). Elderly T2DM patients with MAFLD had a significantly higher value of HOMA2-IR than those without MAFLD[2.0(1.31-2.8) vs.1.39(0.86-2.06), F=220.826, P<0.01]. After correcting for other confounding factors, binary logistic regression showed that serum RBP was strongly associated with the presence of MAFLD in elderly patients with T2DM( β=0.209, 95% CI: 1.079-1.408, OR=1.232, χ2=9.441, P<0.01). Conclusions:Elevated serum RBP levels are an independent risk factor for the development of MAFLD in elderly T2DM patients, possibly through increased insulin resistance induced by RBP.

ABSTRACT

In this study, a new ileal orthotopic bladder (Urumqi Bladder) modified by our center based on the ileal "W" type orthotopic bladder and Studer bladder was used on 8 patients with invasive bladder cancer. All of patients were male and aged between 54 and 66 years. The history of disease ranged from 1 month to 3 years, including 5 patients with initial onset, 3 patients with ≥2 TURBT history. 6 patients had multiple tumors, tumor size from 0.5 cm to 2.5cm. There were 2 patients with single tumor. Preoperative PET-CT examination showed no distant metastasis and pelvic lymph node enlargement, no urinary tract hydronephrosis, and cystoscopy showed no suspected tumor in the urethra. Preoperative pathological results: high-grade invasive urothelial carcinoma was found in 6 cases and muscular invasive urothelial carcinoma in 2 cases. In 8 patients, 50cm ileum was taken from 15cm away from ileocecum after radical cystectomy, which was crimped clockwise inward from the right end into a nearly circular shape, with 10cm left at the left end. The remaining 40cm ileum was formed into 3 sections of about 13cm each, which were decanted to form a storage capsule. The last 10cm intestinal tube was crossed from the front of sigmoid colon. The end of intestine was anastomosed with the left ureter. The right ureter was anastomosed with the top of the right intestine pouch, and the urethra was anastomosed with the pouch to complete the diversion of urine flow. During 3-12 months of postoperative follow-up, 4 patients had short-term mild urinary incontinence. All had complete urinary control at 12 months. 1 patient still had mild left ureter reflux 12 months after surgery, and the other 7 patients had no ureter reflux. In this group of 8 patients, postoperative excretory cystography showed satisfactory effect of bladder voiding, residual, and bladder capacity. Follow-up review of chest CT, urinary CT and abdominal ultrasound showed no hydronephrosis, and no tumor recurrence or distant metastasis.

ABSTRACT

The p21 activated kinase 4 (PAK4) is serine/threonine protein kinase that is critical for cancer progression. Guided by X-ray crystallography and structure-based optimization, we report a novel subseries of C-3-substituted 6-ethynyl-1H-indole derivatives that display high potential and specificity towards group II PAKs. Among these inhibitors, compound 55 exhibited excellent inhibitory activity and kinase selectivity, displayed superior anti-migratory and anti-invasive properties against the lung cancer cell line A549 and the melanoma cell line B16. Compound 55 exhibited potent in vivo antitumor metastatic efficacy, with over 80% and 90% inhibition of lung metastasis in A549 or B16-BL6 lung metastasis models, respectively. Further mechanistic studies demonstrated that compound 55 mitigated TGF-β1-induced epithelial-mesenchymal transition (EMT).

ABSTRACT

Objective:To observe the changes of nutrition impact symptoms (NIS) and fat-free mass and analyze the relationship between them in patients with head and neck cancer (HNC) during radiotherapy.Methods:A convenient sampling method was adopted to select HNC patients who received radiotherapy in the outpatient clinic of department of radiotherapy for head and neck cancer in a cancer hospital in Beijing from March 2017 to January 2020. The nutrition impact symptoms (NIS) were assessed by a nutrition impact symptoms checklist and the fat free mass was assessed by bioelectrical impedance analysis at three time points: before radiotherapy (T1), during radiotherapy (T2) and at the end of radiotherapy (T3). The Generalized Estimating Equations (GEE) was used to analyze the relationship between them.Results:A total of 542 HNC patients were included in the analysis. During radiotherapy, the patients' NIS number and score presented an increasing trend, reaching the highest level and peaked at the end of radiotherapy. The change of fat-free mass showed a decreasing trend and reached the minimum at the end of radiotherapy. Patients with higher NIS scores had more percentage loss of fat-free mass.Conclusions:During radiotherapy, patients with HNC showed an increase in NIS score and lost fat-free mass. Patients with higher NIS score lost more percentage of fat-free mass, which suggested that clinical medical staff should pay attention to NIS management and take comprehensive intervention measures in time to reduce the loss of fat-free mass.

Objective:To evaluate the value of 68Ga-1, 4, 7, 10-tetraazacyclododecane-1, 4, 7, 10-tetraacetic acid (DOTA)-fibroblast activating protein inhibitor (FAPI)-04 PET/CT on assessing different pathological grades in patients with renal fibrosis. Methods:A total of 25 patients (11 males, 14 females; age (39.3±13.9) years) diagnosed with renal fibrosis in the Affiliated Hospital of Southwest Medical University from September 2020 to August 2021 were retrospectively analyzed. All patients underwent renal puncture examination and 68Ga-DOTA-FAPI-04 PET/CT examination. The pathological results of kidney puncture were as the " gold standard" to divide the patients into mild fibrosis (Ⅰ), moderate fibrosis (Ⅱ), and severe fibrosis (Ⅲ). At the same time, 20 patients (10 males, 10 females; age (47.5±13.2) years) who underwent 68Ga-DOTA-FAPI-04 PET/CT examination showed no abnormal uptake of radioactivity in bilateral kidneys and no history of urinary system related diseases were enrolled as normal controls. Parameters including the maximum standardized uptake value (SUV max) of both kidneys, the mean standardized uptake value (SUV mean) of the liver, target/background ratio (TBR), glomerular filtration rate (GFR), and serum creatinine (Scr) were collected. Kruskal-Wallis rank sum test and Bonferroni correction method were used to compare the differences of SUV max, SUV mean, TBR and Scr among groups. One-way analysis of variance and least significant difference (LSD) t test were used to compare the difference of GFR among groups. The receiver operating characteristic (ROC) curve analysis was used to analyze the diagnostic efficacy of SUV max for the degree of renal fibrosis. Results:Of 25 patients, 22 had increased imaging agent uptake and the sensitivity of 68Ga-DOTA-FAPI-04 PET/CT in diagnosing renal fibrosis was 88%. The SUV max and TBR of patients with fibrosis grade Ⅰ, Ⅱ and Ⅲ were significantly higher than those of controls (SUV max: 4.40(3.30, 4.50), 5.90(4.28, 6.48), 8.50(7.50, 9.73) and 1.44(1.38, 1.68); TBR: 6.340±2.389, 8.097±1.420, 11.343±2.002 and 2.986±0.645; H values: 33.685, 32.368, all adjusted P<0.05 (Bonferroni correction method)). The Scr of patients with fibrosis grade Ⅰ and Ⅲ were significantly different (70.1(55.4, 92.5) and 174.1(161.4, 498.2) μmol/L; H=9.770, adjusted P<0.05 (Bonferroni correction method)). The liver SUV mean of patients with renal fibrosis grades Ⅱ and Ⅲ were significantly higher than that of controls (0.673±0.129, 0.751±0.170 and 0.514±0.142; H=15.609, both adjusted P<0.05 (Bonferroni correction method)). The GFR of patients with fibrosis grade Ⅲ had significant differences with grade Ⅰ and Ⅱ ((27.867±15.747), (87.756±31.657) and (63.160±29.556) ml/min; F=8.298, both P<0.05). ROC curve analysis showed that the area under curve was 0.946 7 (95% CI: 0.899 6-0.993 8, P<0.001). Conclusion:68Ga-DOTA-FAPI-04 PET/CT has a certain value in evaluating the degree of renal fibrosis, which can be used as a supplementary examination method for diagnosing renal fibrosis.

ABSTRACT

Objective:To evaluate the effect of job-transfer training for psychiatrists in Henan province in 2018 and to compare them with the results of 2016.Methods:Data of the trainees were collected through questionnaires in 2017 and 2019 respectively. The influencing factors of knowledge and skills were determined by Multiple linear regression analysis; baseline data, training intention, training feedback and the proficiency of knowledge and skills were compared by independent sample t test and chi-square test. Results:The overall satisfaction rate for training was 98.3%, and the overall mastery rate of training knowledge and skills was 59.2% in year 2018. Compared with 2016, the willingness to participate in training, the satisfaction rate, the recognition degree of " 1+ 10+ 1" training mode, the degree of mastery and practical application of training knowledge and skills increased( P<0.05). There were statistically significant differences in the distribution of the primary reasons for participating in the training, factors hindering their participation in the training, and the causes for their failure to fully apply their learning to practice( P<0.01). The results showed that scope of practice, title, intention, and interest in psychiatry was related to the mastery of training knowledge and skills( P<0.05). Conclusions:The effect of training in 2018 is better than 2016, and the degree of mastery and practical application of training knowledge and skills should be increased.
