RESUMEN
Objective:To explore the "Internet + nursing service" model based on the nurse-patient safety needs, and provide reference for development of "Internet + nursing service".Methods:The First Affiliated Hospital of Sun Yatsen University established a "Internet+ nursing service" management team in December 2019, developed an information platform, formulated and implemented a specific plan of the "Internet+ nursing service" model, including service objects, service projects and service modes. After the smooth operation of this model, the statistics of the nursing service projects and service times that had been carried out from September 2020 to March 2021, as well as the satisfaction of 21 patients who received nursing services would be counted.Results:From September 2020 to March 2021, 21 patients were provided with 55 on-site nursing services, and 151 operations in 16 projects were completed. No nursing-related adverse events occurred. The patients gave all five-star evaluations to the door-to-door service, the satisfaction score was 5 points, and the overall evaluation was 99.88 points.Conclusions:The pilot work of "Internet + nursing service" based on the nurse-patient safety needs has met the care needs of discharged patients and the safety needs of door-to-door services, guarantee the safety of nurses' door-to-door service effectively. And it provides reference for the development and improvement of "Internet + nursing service" related safety work in tertiary A-level hospitals.
RESUMEN
Small cell lung cancer (SCLC) is a rapidly developing malignant tumor, which is highly heterogeneous and prone to drug resistance, and the prognosis is usually poor. Poly ADP-ribose polymerase (PARP) inhibitors target the DNA damage response pathway, preventing DNA repair, thereby exerting anti-tumor effects. Currently, PARP inhibitors are used as monotherapy or in combination with DNA-damaging agents or immune checkpoint inhibitors in the treatment of SCLC. Although the current research results are limited, it can be seen that PARP inhibitors may be a breakthrough in the targeted therapy of SCLC.
RESUMEN
Tuberous sclerosis complex(TSC)is an autosomal dominant skin-nerve syndrome with diverse clinical manifestations.Epilepsy is the most common neurological manifestation.Vigabatrin(VGB)is an inhibitory neurotransmitter γ-aminobutyric acid(GABA)analogue.It reduces the degradation of GABA by irreversibly binding to GABA transaminase, thereby increasing the level of GABA in the central nervous system and exerting anti-epileptic effects.It is suitable for the treatment of various types of epilepsy related to TSC.In recent years, the preventive effect of VGB in TSC-related epilepsy has attracted wide attention.There is a certain degree of adverse reactions during the use of VGB, the most noteworthy of which is the visual field and central nervous system changes.This article reviews the efficacy and safety of VGB in the treatment of TSC-related epilepsy.
RESUMEN
Fluorine is a non-metallic chemical element, which often exists in the form of fluoride in nature. Long-term excessive intake of fluoride will lead to chronic fluorosis. Fluoride is mainly absorbed through the digestive tract, so the intestinal tract is more vulnerable to fluoride damage. Excessive fluoride not only destroys intestinal structure and interferes with intestinal flora and micro-environment, but also induces intestinal toxicity through oxidative stress. This article reviews the effects of fluoride on intestinal structure and defense function, aiming to provide theoretical references and new ideas for the mechanism study of fluoride-induced intestinal damage.
RESUMEN
Objective To evaluate the effect of applying sitting posture corrector on improving reading and writing posture of elementary school students， and provide scientific evidence for prevention and control of myopia in children and adolescents. Methods One elementary school each in urban and suburban areas of Shanghai was selected using a convenience sampling strategy. Furthermore， two classes each in Grade 3 and 4 were selected as the intervention group （282 students were included in the study）， and the other two classes each in Grades 3 and 4 were selected as the control group （294 students were included in the study）. Students in the intervention group used the sitting posture corrector in the classrooms for 4 months （from September 2020 to January 2021）， while those in the control group did not use the sitting posture corrector. Relevant data were collected before and after the intervention through a self-administered questionnaire and visual examination. Statistical analysis was performed using chi-square test and generalized estimating equation. Results Before the intervention， 13.5% （38/282） of students in the intervention group and 12.2% （36/294） in the control group had good reading and writing posture （ χ 2 = 0.195， P >0.659）. After the intervention， 18.4% （52/282） of students in the intervention group had good reading and writing posture， which was higher than that （11.2%， 33/294） in the control group （ χ 2=5.957， P =0.015）. Before and after the intervention， there was no significant differences in the prevalence of myopia between students in the intervention and control groups （all P >0.05）. Generalized estimating equation analysis showed that students in the intervention group were 1.502 times more likely to have good reading and writing posture than those in the control group after the intervention （ P =0.043）. Conclusion Applying sitting posture corrector in schools could improve students' reading and writing posture.

RESUMEN
Multidrug resistance(MDR)is one of the important reasons for the failure of chemotherapy in clinic,whereas the mechanism of MDR is very complicated. At present,it is considered that the efflux protein P-glycoprotein(P-gp)is one of the main factors which can lead to MDR,descreasing the successful rate of chemotherapy because chemotherapeutics with different structures and functions can be effluxed by P-gp. Flavonoids are found in many kinds of plants and have a wide range of pharmacological activi?ties. Besides,recent studies have reported that flavonoids can reverse the MDR of tumor and affect the expression and function of ef?flux transporter,especially P-gp. In this review,we elucidate the mechanisms of flavonoids reversing tumor MDR mediated by P-gp from the following aspects:inhibition of P-gp protein expression,inhibition of P-gp efflux function,and prevention of combining P-gp and its substrate,etc. The review can provide some ideas and references for the application of flavonoids in tumor therapy.
