ABSTRACT

Aim To explore the effect of kaempferol-7- 0-neohesperidoside (K70N) against prostate cancer (PCa) and the underlying mechanism. Methods The effect of K70N on the proliferation of PCa cell lines PC3, DU145, C4-2 and LNCaP was detected using CCK8 assay. The effect of K70N on migration ability of DU145 cells was determined by wound healing assay. The targets of K70N and PCa were screened from SuperPred and other databases. The common targets both related to K70N and PCa were obtained from the Venny online platform, a protein-protein interaction network (PPI) was constructed by the String and Cyto- scape. Meanwhile, the GO and KEGG functional enrichment were analyzed by David database. Then, a "drug-target-disease-pathway" network model was constructed. Cell cycle of PCa cells treated with K70N was analyzed by flow cytometry. The expressions of cycle-associated proteins including Skp2, p27 and p21 protein were detected by Western blot. Molecular docking between Skp2 and K70N was conducted by Sybyl X2. 0. Results K70N significantly inhibited the proliferation and migration of PCa cells. A total number of 34 drug-disease intersection targets were screened. The String results showed that Skp2 and p27, among the common targets, were the key targets of K70N for PCa treatment. Furthermore, GO and KEGG functional en-richment indicated that the mechanism was mainly related to the cell cycle. Flow cytometry showed that K70N treatment induced cell cycle arrest at the S phase. Compared with the control group, the protein expression level of Skp2 was significantly down-regulated, while the protein expression levels of p27 and p21 were up-regulated. The network molecular docking indicated that the ligand K70N had a good binding ability with the receptor Skp2. Conclusions K70N could inhibit the proliferation and migration of PCa cells, block the cell cycle in the S phase, which may be related to the regulation of cell cycle through the Skp2- p27/p21 signaling pathway.

ABSTRACT

In recent years, with the development of ophthalmic therapeutic drugs, the vitreous body, as a channel for the treatment of ophthalmic diseases, especially fundus diseases, has opened up a new therapeutic approach for various choroidal neovascular diseases, macular edema, uveitis and other diseases associated with fundus diseases, which is represented by wet age-related macular degeneration (wAMD). The drugs administered through the vitreous body mainly include ocular anti-vascular endothelial growth factor (VEGF) injections, microplasmin and hormones. For this kind of ophthalmic products, there are no clear technical guidelines and norms for non-clinical research at home and abroad. This article combines review practices and cases of marketed products to sort out the research progress and considerations on non-clinical studies of ophthalmic drugs dosing through the ocular vitreous body, in order to provide references for the research and evaluation of such drugs.

ABSTRACT

Objective:To report a SPTLC2 gene mutation in a family with a phenotype of Charcot-Marie-Tooth disease.Methods:To screen the family of patients with pathogenic mutations of SPTLC2 gene from the database of hereditary peripheral neuropathy in the Department of Neurology, Peking University First Hospital, and to collect their clinical data, peripheral nerve conduction examination, nerve ultrasound examination, pathological examination of the peroneal nerve and whole exome sequencing results of prohand.Results:One family was screened, the proband was a 16-year-old female with 4 years of sensory loss and anhidrosis of both lower limbs and 16 months of walking difficulty who admitted to Peking University First Hospital in January 2022. Physical examination showed sensory loss, dry skin and weakness in distal limbs. Her father had numbness and dry skin in the distal lower limbs from childhood,weakness and atrophy of his lower limbs in adulthood. He died at age of 52 years old. The nerve conduction study revealed no action potentials of the sensory and motor nerves of the lower limbs in the proband. The amplitude of the compound muscle action potential of the motor conduction of the bilateral ulnar nerve and median nerve decreased, and the nerve conduction velocity of the bilateral median nerve were 32 m/s and 24 m/s. Neurosonography showed thickening of peripheral nerves. Sural biopsy revealed severe loss of myelinated and unmyelinated nerve fibers with onion bulbs formation. SPTLC2 gene showed a known heterozygous p.G435V mutation. The lower limb weakness was improved after oral L-serine.Conclusions:SPTLC2 gene mutation can lead to an intermediate Charcot-Marie-Tooth disease phenotype. L-serine can improve the limb weakness.

ABSTRACT

Objective:To analyze the application value of narrative education model in clinical teaching of nurses in operating room.Methods:A total of 90 nursing students in the Department of Operating Room, Shanghai Tenth People's Hospital from January 2018 to January 2020 were selected as the research objects and randomly divided into observation group and control group, 45 in each group. The control group was taught by traditional mentoring method, and the observation group was taught by narrative education model. The two groups of nursing students practiced for 4 weeks. After the teaching, the scores of theoretical knowledge and operation were compared between the two groups. The scores of career identity scale and caring ability evaluation scale of the two groups were compared, the scores of each dimension of Chinese registered nurse core competence scale (CIRN) were evaluated, and the feedback of the two groups of nursing students on the teaching methods was analyzed. SPSS 22.0 was used to conduct t-test and chi-square test. Results:The scores of theoretical knowledge and operation in the observation group were (94.52±5.34) points and (88.67±3.98) points, respectively, which were significantly higher than those [(85.67±5.26), (82.24±4.16)] in the control group ( t=7.92, 7.49, all P<0.001). The scores of professional identity scale and caring ability evaluation scale in the observation group were (39.12±5.12) points and (193.14±11.24) points, respectively, which were significantly higher than those [(34.21±4.23), (180.23±11.35)] in the control group ( t=4.96, 5.42, all P<0.001). The scores of various dimensions of CIRN in the observation group were significantly higher than those in the control group ( t=4.72, 7.57, 4.13, 4.66, 6.19, 4.27, 5.48, all P<0.001). The feedback of nursing students in the observation group on teaching methods was significantly better than that in the control group ( χ2=4.29, 6.48, 12.26, 4.44, 7.60, 5.03, P<0.05).

ABSTRACT

Objective: To evaluate the effectiveness and safety of Pul-Stent as the treatment of postoperative branch pulmonary artery stenosis in children with congenital heart disease. Methods: This was a retrospective study. Thirty-three patients who underwent Pul-Stent implantation in Shanghai Children's Medical Center due to postoperative residual pulmonary artery stenosis from August 2014 to June 2015 were included. The immediate curative effect, follow-up and complications of Pul-Stent implantation were assessed. Comparisons between groups were performed with unpaired Student t test. Results: Pul-Stent implantation of 33 patients (19 males and 14 females) were performed successfully. Thirty-one patients underwent percutaneous stenting, and 2 patients underwent hybrid stenting. A total of 35 Pul-Stents were implanted (19 of model small, 15 of model medium and one of model large), 23 stents were planted in the proximal left pulmonary artery and 12 stents were in the proximal right pulmonary artery. The initial diameter of dilation balloon ranged from 6 to 16 mm, and the long sheath of percutaneous implantation ranged from 8 to 10 F in 29 patients (29/31, 94%). After stenting, the diameter of the narrowest segment of pulmonary artery increased from (4.0±1.7) mm to (9.1±2.1) mm in all patients (t=-21.60, P<0.001). The pressure gradient at the stenosis in 26 patients after biventricular correction decreased from (30.5±12.3) mmHg (1 mmHg=0.133 kPa) to (9.9±9.6) mmHg (t=12.92, P<0.001), and the right ventricular to aortic pressure ratio decreased from 0.57±0.14 to 0.44±0.12 (t=7.44, P<0.001). The pressure of the superior vena cava after stenting in 5 patients after cavopulmonary anastomosis decreased from (17.0±1.9) mmHg to (14.0±0.7) mmHg (t=2.86, P=0.046). Two patients died during reoperation for repairing other cardiac malformations. The remaining 31 patients were clinically stable during the follow-up period of (5.3±1.6) years, and one stent fracture was found on chest X-ray. Cardiac catheterization reexaminations in 16 patients showed that restenosis was found in one stent, while stent position and patency were satisfactory in the remaining stents. Nine children underwent post-dilation without stent fracture, displacement or aneurysm formation. Cardiac tomography showed no stent stenosis, fracture observed, or significant change in diameter of the stent in 8 patients. The inner diameter and pulmonary blood perfusion could not be accurately evaluated due to artifacts by cardiac magnetic resonance imaging in 4 patients. Conclusions: Pul-Stent has good compliance and adequate radial strength, and can dilate further over time to accommodate for somatic growth. It performs safely and effectively in treating post-operative branch pulmonary artery stenosis in children.

ABSTRACT

Objective:To improve the clinician′s recognition of the clinical and molecular characteristics of primary familial brain calcification (PFBC).Methods:The detailed clinical information, imaging and molecular characteristics were analyzed in proband and family members of a genetically confirmed autosomal recessive PFBC family. The clinical and imaging features of junctional adhesion molecule 2 (JAM2) gene related PFBC were analyzed in combination with the literature review.Results:The proband was a 32-year-old man, with slurred speech and paroxysmal limb twitch as the first symptoms, accompanied by cognitive dysfunction, and rigidity in the limbs, with epilepsy in the past. Brain CT showed extensive, symmetrical, and bilateral calcification involving the cerebellum, basal ganglia, thalamus, subcortex and cortex. Other family members showed no related clinical symptoms. Brain CT of the parents of the proband showed no calcification. Gene testing of the proband revealed a homozygous c.685C>T(p.R229*) mutation in JAM2 gene, which has been reported as a pathogenic variation abroad, whereas has not been reported in China. The proband′s parents and children were found with heterozygous c.685C>T (p.R229*) mutation.Conclusions:Autosomal recessive inherited PFBC is a rare disease, and JAM2 mutation is a newly discovered pathogenic gene of PFBC in 2020. Patients with intracranial calcification should be alert of JAM2 gene mutation.

ABSTRACT

Objective: To investigate the gene expression characteristics of peripheral blood mononuclear cells from patients with high altitude pulmonary hypertension (HAPH) in Naxi residents living in Lijiang, Yunnan, and to explore the underlying pathogenesis and value for potential drug selection. Methods: This is a case-control study. Six patients with HPAH (HPAH group) and 4 normal subjects (control group) were selected from the Naxi residents who originally lived in Lijiang, Yunnan Province. The general clinical data of the two groups were collected, and the related indexes of pulmonary artery pressure were collected. Peripheral blood mononuclear cells of the subjects were collected for RNA sequencing. The differences on gene expression, regulatory network of transcription factors and drug similarity between the two groups were compared. The results were compared with the public data of idiopathic pulmonary arterial hypertension (IPAH). Biological processes and signal pathways were analyzed and compared between HPAH and IPAH patients. Results: The age of 6 patients with HAPH was (68.1±8.3) years old, and there were 2 males (2/6). The age of 4 subjects in the control group was (62.3±10.9) years old, and there were 2 males (2/4). Tricuspid regurgitation velocity, tricuspid pressure gradient and pulmonary systolic pressure in HAPH group were significantly higher than those in control group (all P<0.05). The results of RNA sequencing showed that compared with the control group, 174 genes were significantly upregulated and 169 genes were downregulated in peripheral blood mononuclear cells of HAPH group. These differentially expressed genes were associated with 220 biological processes, 52 molecular functions and 23 cell components. A total of 21 biological processes and 2 signal pathways differed between HPAH and IPAH groups, most of which were related to inflammation and immune response. ZNF384, SP1 and STAT3 were selected as highly correlated transcription factors by transcription factor prediction analysis. Trichostatin A and vorinostat were screened out as potential drugs for the treatment of HAPH by drug similarity analysis. Conclusions: There are significant differences in gene expression in peripheral blood monocytes between HAPH patients and normal population, and inflammation and immune dysfunction are the main pathogenic factors. Trichostatin A and Vorinostat are potential drugs for the treatment of HAPH.

ABSTRACT

OBJECTIVE@#To investigate the incidence and related risk factors of healthy side fracture after hip fracture surgery in the elderly, so as to provide basis for the prevention of re-fracture.@*METHODS@#The data of 452 patients over 65 years old with femoral neck fracture or intertrochanteric fracture treated with hip arthroplasty or proximal femoral intramedullary nailing from June 2012 to June 2017 were analyzed, including 168 males and 284 females, the age ranged from 65 to 97(75.5±7.5) years. There were 191 cases of femoral neck fracture and 261 cases of femoral intertrochanteric fracture. According to whether there was a fracture in the healthy hip after operation, the patients were divided into fracture group and no fracture group. The gender, age, body mass index, fracture type, initial treatment method, bone mineral density, bed time, medical compliance, postoperative short-term delirium, whether there were medical diseases before injury and Harris score of hip joint in the final follow-up were recorded. Univariate Logistic regression analysis was used to screen out the risk factors of healthy side fracture after operation, and then statistically significant risk factors were included in multi factor Logistic regression analysis to screen out the independent risk factors of healthy side fracture after operation of hip fracture in the elderly.@*RESULTS@#Among them, 42 of the 452 patients had hip fractures on the healthy side with an incidence of 9.3%. The average interval between the two fractures was (2.9±2.1) years. Univariate Logistic regression analysis showed that there were significant differences in age, bone mineral density, medical compliance, short-term postoperative deliriun, pre-injury complicated with medical diseases and Harris score of hip joint in the final follow-up (P<0.05). Multivariate Logistic analysis showed that age(OR=4.227), bone mineral density(OR=4.313), combined with medical diseases (OR=5.616) and low hip Harris score at the final follow-up (OR=3.891) were independent risk factors for healthy side fractures after hip fracture surgery in elderly(P<0.05).@*CONCLUSION@#The age, bone mineral density, combined with medical diseases and low Harris score of hip joint in the final follow-up are the main risk factors of healthy side fracture after hip fracture in the elderly. It is necessary to strengthen the treatment of medical diseases, anti osteoporosis and improve hip joint function within 3 years after operation, so as to prevent the occurrence of healthy side hip fracture.

ABSTRACT

Objective: To explore the clinical characteristics, treatment methods and outcomes of extramedullary plasmacytoma of the head and neck. Methods: A retrospective analysis was conducted on 10 cases with extramedullary plasmacytoma of the head and neck who were admitted to Henan Tumor Hospital from January 2005 to January 2020. Among the 10 patients, 6 were male and 4 were female. The average age at diagnosis was 56.3 years old (34-74 years old). Among them, 3 cases were located in the nasal cavity, 2 cases in the nasopharynx, 1 case in the sinuses, 2 cases in the larynx, 1 case in the oropharynx, and 1 case in the cervical lymph nodes. Treatments were administered according to tumor size and resection extent. Complete surgical excision (negative margins) was preferred, followed by adjuvant radiotherapy or radiotherapy alone. The clinical characteristics, diagnosis, treatment and prognosis of EMP were analyzed. Results: The patients' symptoms were not specific, frequently with local obstruction symptom and localized masses. All patients were confirmed pathologically as suffering from monoclonal plasmacytoma, with negative bone marrow biopsy and negative skeletal survey. Five patients received surgery, 3 received radiotherapy, and 2 received surgery with additional radiation. The follow-up time was 16-125 months, with a median of 92 months. Two patients developed into multiple myeloma. One patient who received radiotherapy after surgery relapsed after 7 years of follow-up and again received surgical treatment, with no evidence of second recurrence. The remaining patients had no recurrence or progression. Conclusion: Extramedullary plasmacytoma of the head and neck has a good prognosis. Surgical treatment can be considered for completely resectable lesions.

Puerarin has the anti-Alzheimer's disease (AD) activity,which can reverse nerve injury induced by Aβand inhibit neuronal apoptosis.However,its potential pharmacodynamic mechanism still needs to be further researched.The occurrence and development of AD is due to the change of multiple metabolic links in the body,which leads to the destruction of balance.Puerarin may act on multiple targets and multiple metabolic processes to achieve therapeutic purposes.Quantitative proteomic analysis provides a new choice to understand the mechanism as completely as possible.This research adopted SH-SY5Y cells induced by Aβ_(1-42)to establish AD cell model,and Aβimmunofluorescence detection showed that Aβdecreased significantly after puerarin intervention.The mechanism of puerarin reversing SH-SY5Y cell injured by Aβ_(1-42)was further explored by using label-free non-labeled quantitative technology and Western blot detection based on bioinformatics analysis result.The results showed that most of the differential proteins were related to biological processes such as cellular component organization or biogenesis,cellular component organization and cellular component biogenesis,and they mainly participated in the top ten pathways of P value such as pathogenic Escherichia coli infection,m TOR signaling pathway,regulation of autophagy,regulation of actin cytoskeleton,spliceosome,hepatocellular carcinoma,tight junction,non-small cell lung cancer,apoptosis and gap junction.Annexin V/PI flow cytometry and TUNEL were used to detect apoptosis,and the results showed that Aβdecreased significantly and the rate of apoptosis decreased significantly after puerarin intervention.Western blot analysis found that the protein expression level of autophagy related protein LC3Ⅱwas up-regulated after Aβinduction,and the degree of this up-regulation was further enhanced in puerarin intervention group.The trend of the ratio of LC3Ⅱ/LC3Ⅰamong groups was the same as the protein expression level of LC3Ⅱ,the protein expression level of p62 in the control group,AD model group and puerarin intervention group decreased successively.Protein interaction network analysis showed that CAP1 was correlated with TUBA1B,HSP90AB2P,DNM1L,TUBA1A and ERK1/2,and the correlation between CAP1 and ERK1/2 was the highest among them.Western blot showed that the expressions of p-ERK1/2,Bax and CAP1 were significantly down-regulated and the protein expression level of Bcl-2 was significantly up-regulated after puerarin intervention.Therefore,puerarin might improve the SH-SY5Y cells injured by Aβ_(1-42)through the interaction of multiple biological processes and pathways in cells multiple locations,and CAP1 might play an important role among them.

ABSTRACT

Purpose@#This study was aimed to evaluate the clinical significance and prognostic value of CRP/albumin ratio (CAR) in patients with gastric cancer. @*Methods@#The data of 205 gastric cancer patients who underwent surgery was analyzed retrospectively. The association of CAR with the clinical features and prognostic value in gastric cancer was analyzed. The data of this study was combined with previous studies to further determine the prognostic value of CAR in patients with gastric cancer using a metaanalysis method. @*Results@#Cox analysis revealed that preoperative CAR was an independent prognosis indicator in patients with gastric cancer. High expression of CAR indicated a shorter survival time than in those with lower expression. CAR has a higher prognostic value in the 1-, 3-, and 5-year overall survival in patients with gastric cancer. CAR showed significant difference regarding the gastric cancer patients’ age, M stage, and clinical stage. The discriminate value of CAR in M stage of gastric cancer was high (area under the curve, 0.809). A meta-analysis combining previous data and our data showed that preoperative CAR demonstrated a significant association with the overall survival of patients with gastric cancer. @*Conclusion@#This study demonstrated that preoperative CAR could serve as an important prognostic indicator in patients with gastric cancer.

ABSTRACT

Objective: To study the influencing factors of DNA double-strand breaks (DSB) repair capacity and relationship with differentiated thyroid cancer (DTC). Methods: A total of 140 patients with thyroid diseases admitted to the Henan Cancer Hospital from January 2020 to March 2020 were retrospectively analyzed, including 26 males and 114 females, aged from 18 to 78 years old. According to the pathological results, the patients were divided into DTC group (90 cases) and control group or benign thyroid nodules (BTN) group (50 cases). The DSB repair ability of peripheral blood T lymphocytes was measured by flow cytometry. The data of two groups were compared by Wilcoxon rank sum test to evaluate the relationship between DSB repair ability and the risk of DTC. According to the median repair ability of DSB in BTN group, the repair ability of DSB was divided into high and low categories, and the factors influencing the repair ability of DSB were analyzed by Logistic regression method. SPSS 22.0 software was used to analyze the data. Results: The DSB repair capacity was 27.87% in DTC group and 36.75% in BTN group, with significant difference (Z=-3.999,P<0.05). Logistic regression analysis suggested that patients with thyroid cancer had lower DSB repair capacity than patients without cancer (OR=2.245; 95%CI: 1.067-4.725; P=0.033), and patients with a history of radiation exposure had a reduced DSB repair capacity (OR=2.698; 95%CI: 1.271-5.725, P=0.010). Conclusion: The risk of DTC increases in patients with low DSB repair capacity. Radiation exposure is a risk factor for the reduction of DSB repair capacity.

ABSTRACT

Objective@#To analyze the status of follow-up cell testing of HIV/AIDS cases among young students aged 15-24 in Guangdong Province from 2008 to 2019.@*Methods@#Using the historical database downloaded from the AIDS Comprehensive Prevention and Control Information System from January 1, 2018 to December 31, 2019, eligible newly discovered cases were screened by year and were linked with follow-up database. Joinpoint regression model and trend test were used to explore the annual changes in the follow-up and CD4 testing status, and Logistic regression was used to analyze relevant influencing factors.@*Results@#The number of infected students showed a rapid upward trend before 2015(APC=41.7,β=0.3,P<0.01), and the growth rate slowed down(APC=3.6,β=-0.3,P<0.01). The proportion of follow-up and CD4 testing completed within one year increased from 58.3% in 2008 to 93.6% in 2019, and the timely detection rate increased from 33.3% in 2008 to 86.2% in 2019. The Cochran Armitage trend test was statistically significant. Pairwise comparison test showed time trends of the idnex differed in regions and education groups (Z=4.7,8.7,9.8,P<0.01). The Pearl River Delta region, cases from other cities in the province, with precise transmission routes, from voluntary counseling and testing, and cases flowing within the province, the proportion of follow up and testing completed within one year is relatively high (P<0.05).@*Conclusion@#The growth rate of HIV/AIDS cases among young students aged 15-24 in Guangdong Province has slowed down in recent years. The route of infection, source and flow of cases affect follow-up and testing compliance. And to do a good job of referrals for off-site mobility, and explore and promote student-friendly VCT service models.
