Synaptic dysfunction plays an important role in the early stage of frontotemporal dementia (FTD), and there are differences in the pattern of synaptic damage in different genotypes. GRN gene mutations are rare in the Chinese population, and there are no reports of synaptic damage patterns in GRN mutations or semantic variant primary progressive aphasia (svPPA). The synaptic injury characteristics of a patient with svPPA harboring GRN gene mutations, which was characterized by decreased synaptic density in the left frontal, temporal, parietal lobe and contralateral cerebellum were reported in this article. The underlying mechanism of synaptic dysfunction involved in the disease process, and potential targets for future clinical interventions were indicated.

Objective To investigate the influencing factors of the indwelling catheter time in patients with prostate hyperplasia and malignant tumor after prostate surgery.Methods A total of 447 prostate surgery patients with prostate hyperplasia and malignant tumor were selected for medical record review using convenience sampling method. The demographic data,diagnose,complications,surgical method,medical advice and nursing care items were collected. The indwelling catheter time in or outward of the hospital and its influence factors were analyzed.ResultsA number of 300(44.74%) patients had urination disorders before operation.A number of 258(57.72%) patients had complications. Little information about rehabilitated exercise of urination function was recorded.There were statistically significant differences in indwelling catheter time in the hospital among benign prostatic hyperplasia patients with different education levels, health payments and complications (t/F=5.048, -2.433, 2.086;P<0.05). Significant differences in indwelling catheter time outward of the hospital were also observed in patents with different preoperative urination disorders (t=0.551, P<0.05). Prostate malignancy patients with different resident places and bad habits had statistically significant differences in indwelling catheter time outward of the hospital (t=2.062, -1.974;P<0.05). For patients with benign prostatic hyperplasia, education levels, health payment and complications could explain 60.8% of changes in indwelling catheter time in the hospital. For patients with prostate malignancy, resident place and bad habits could explain 68.4% of changes in indwelling catheter time outward of the hospital. According to medical records, only 42.5% patients had urinary flow rate, urodynamic and residual urine volume examinations. Only 17.4% of medical records had urinary function related admission, which were found in 26.4% of medical records when patients were discharged.ConclusionsMedical workers are lack of attentions to the rehabilitated exercise of urination function for patients with prostate hyperplasia and malignant tumor after prostate surgery. It is urgent to build a scheme of rehabilitated exercise of urination function for postoperative patients of prostate, which based on the fast-track surgery theory and used the time as axis.

Objective:To systematically retrieve, evaluate, and summarize the best evidence of self-management in patients with gastroesophageal reflux disease, so as to provide references for clinical nurses to formulate self-management intervention programs for patients with gastroesophageal reflux disease.Methods:Through systematic retrieval of domestic and foreign guides and literature databases, the quality of the included literature was evaluated separately according to requirements of literature quality evaluation. Experts were invited to evaluate the summarized evidence according to the feasibility, appropriateness, meaningfulness, and effectiveness (FAME) structure.Results:A total of 9 articles were included. Finally, the 5 aspects of diet, lifestyle, medication, abdominal breathing training, and follow-up of patients with gastroesophageal reflux disease were summarized, and a total of 21 best recommendations were made.Conclusions:The best evidence for self-management intervention in patients with gastroesophageal reflux disease is rich in content. In clinical work, clinical nurses should apply relevant evidence based on the specific circumstances of the hospital, combined with the promotion and obstacle factors of evidence application.

Background:Of patients with acute severe ulcerative colitis (ASUC),30% -40% is steroid-refractory and required second-line medical therapy or colectomy. Infliximab (IFX)may be effective as rescue therapy. Aims:To explore preliminarily the efficacy and safety of IFX as rescue therapy in ASUC in China. Methods:A retrospective study was conducted in 10 consecutive ASUC patients receiving IFX as rescue therapy from June 2012 to September 2016 at Peking Union Medical College Hospital. The modified Mayo score and laboratory parameters were compared at baseline and on week 2,week 12 and week 30 of the treatment course. Results:The response rates on week 2,week 12 and week 30 of IFX treatment were 90. 0% (9/ 10),90. 0% (9/ 10)and 71. 4% (5/ 7),respectively,and the remission rates were 20. 0% (2/10),30. 0% (3/ 10)and 28. 6% (2/ 7),respectively. One patient was primary non-responder to IFX,and two lost response on week 30 (secondary non-response). Seven patients were followed up for 38 weeks. Two patients underwent colectomy. After (9. 6 ± 7. 0)months on average,endoscopic improvement occurred in 50. 0% (5/ 10)of patients,of which one achieved mucosal healing. During treatment course,one case of herpes zoster virus infection and one case of cytomegalovirus infection were recorded. Conclusions:This retrospective study revealed good short-term response to IFX treatment in patients with ASUC in China. It may reduce colectomy rate and promote mucosal healing. However,the rate of secondary loss of response is relatively high. During treatment course,viral infection should be monitored.

Tumor has become one of the major diseases threatening human health at present. Conventional therapies for tumor have serious side effects and are prone to drug resistance， while new therapies are expensive and impose a heavy burden on patients. Chinese herbs effective in the treatment of tumor contain a variety of natural active ingredients， and many anti-tumor drugs used in clinical practice are derived from Chinese herbs. Polysaccharides， ubiquitous in Chinese herbs， are easy to extract and have antitumor， antiviral， and antioxidant activities. Studies have demonstrated that the polysaccharides from Chinese herbs have significant anti-tumor effect and are characterized by multi-target and multi-mechanism functioning， which can avoid the development of drug resistance， exhibiting a great research value and the potential to be developed into novel anti-tumor drugs. Their anti-tumor mechanisms mainly include the inhibition of tumor proliferation， promotion of apoptosis， induction of autophagy， influence on cell cycle， inhibition of tumor angiogenesis， modulation of epithelial-mesenchymal transition （EMT） and immunity， promotion of tumor oxidative stress， and regulation of phosphatidylinositol 3-kinase/ protein kinase B （PI3K/Akt）， Toll-like receptor 4 （TLR4）， mitogen-activated protein kinase/nuclear factor-kappa B （MAPK/NF-κB）， adenosine 5'-monophosphate （AMP）-activated protein kinase/mechanistic target of rapamycin （AMPK/mTOR）， epidermal growth factor receptor/extracellular signal-regulated kinase （EGFR/ERK）， p53， and Wnt/β-catenin signaling pathways.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection has spread worldwide and threatened human's health. With the passing of time, the epidemiology of coronavirus disease 2019 evolves and the knowledge of SARS-CoV-2 infection accumu-lates. To further improve the scientific and standardized diagnosis and treatment of maternal SARS-CoV-2 infection in China, the Chinese Society of Perinatal Medicine of Chinese Medical Association commissioned leading experts to develop the Recommendations for the Diagnosis and Treatment of Maternal SARS-CoV-2 Infection under the guidance of the Maternal and Child Health Department of the National Health Commission. This recommendations includes the epidemiology, diagnosis, management, maternal care, medication treatment, care of birth and newborns, and psychological support associated with maternal SARS-CoV-2 infection. It is hoped that the recommendations will effectively help the clinical management of maternal SARS-CoV-2 infection.

Objective:To investigate the regulatory effect of transient receptor potential cation channel subfamily C member 3 (TRPC3) on the retina in oxygen-induced retinopathy (OIR) mice and biological behavior of human retinal vascular endothelial cells (HREC).Methods:A total of 32 healthy SPF grade 7-day-old C57BL/6 mice were selected and randomly divided into a control group and an OIR group by the random number table method, with 16 mice in each group.The control group received no special treatment, and the OIR model was established in the OIR group.On postnatal day 17 (PN17), the success of the model establishment was verified by immunofluorescence staining of the retinal patch.The in vitro cultured HREC were divided into a normal control group, a transfection reagent group, and a si-TRPC3 group.The normal control group received no special treatment, while the transfection reagent group and the si-TRPC3 group were transfected with transfection reagent or transfection reagent + si-TRPC3.The relative expression of TRPC3 mRNA was detected by real-time quantitative fluorescence PCR.The relative expressions of TRPC3, transcription factor NF-E2 related factor (Nrf2), and superoxide dismutase (SOD) proteins were determined by Western blot.HREC were further divided into a normal control group, a vascular endothelial growth factor (VEGF) group, a si-TRPC3 group, and a Pyr3 (TRPC3 channel inhibitor) group, which were cultured in complete medium, medium containing 20 ng/ml VEGF recombinant protein, medium containing 20 ng/ml VEGF recombinant protein (si-TRPC3 transfection for 72 hours), and medium containing 20 ng/ml VEGF recombinant protein+ 1 μmol/L Pyr3 for 48 hours, respectively.The proliferation ability of HREC was detected using cell counting kit 8 (CCK-8). The horizontal and vertical migration ability of cells were detected by cell scratch assay and transwell assay, respectively.This study followed the 3R principles of animal welfare and was approved by the Ethics Committee of Hebei Eye Hospital (No.2023LW04). Results:Pathological neovascular clusters with strong fluorescent staining appeared in the retina of OIR mice on PN17.The relative expressions of TRPC3 mRNA and protein in the retina of OIR mice were 2.057±0.244 and 1.517±0.290, respectively, significantly higher than 0.983±0.033 and 0.874±0.052 of control group ( t=6.165, 3.094; both at P<0.05). The relative expression levels of TRPC3 mRNA and protein were significantly lower, and the relative expression levels of Nrf2 and SOD proteins were higher in the si-TRPC3 group than in the normal control and transfection reagent groups, and the differences were statistically significant (all at P<0.05). The CCK-8 experiment results showed that the cell absorbance value was higher in the VEGF group than in the normal control group, and lower in the si-TRPC3 and Pyr3 groups than in the VEGF group, with statistically significant differences (all at P<0.05). The results of the cell scratch experiment showed that the lateral migration rate of VEGF group cells was higher than that of normal control group, while the lateral migration rate of si-TRPC3 group and Pyr3 group cells was lower than that of VEGF group, and the differences were statistically significant (all at P<0.05). The transwell experiment results showed that the number of stained cells in the VEGF group was higher than that in the normal control group, and the number of stained cells in the si-TRPC3 group and Pyr3 group was lower than that in the VEGF group, with statistically significant differences (all at P<0.05). Conclusions:Hypoxia induces increased TRPC3 expression in OIR mouse retina, and downregulation of TRPC3 inhibits HREC proliferation and migration.The mechanism is related to the activation of the Nrf2-related oxidative stress pathway.
