The spectrum of biopsy-confirmed kidney disease varies with regions and periods. We describe the distribution of pathological types and epidemiological characteristics of kidney diseases in Northwest China due to regional differences in geographical environment, social economy, and dietary habits. Methods: Kidney biopsy cases from 2005 to 2020 in Xijing Hospital were retrospectively analyzed. Pathological characteristics of patients in different periods were analyzed using the t test or chi-square test. Joinpoint regression was used to analyze trends in pathological types and disease spectrum. Results: A total of 10,528 eligible patients were included. Primary glomerular disease (PGD) accounted for the majority of the cases and exhibited an obvious downward trend, whereas secondary glomerular disease (SGD) showed an obvious upward trend. Among PGD, immunoglobulin A nephropathy (IgAN) remained the most common pathological type, and the detection rate of membranous nephropathy (MN) was significantly increased. Among SGD, Henoch-Schönlein purpura nephritis (HSPN) was the most common pathological type and may present a significant characteristic of Northwest China. Diabetic nephropathy (DN) exhibited the most obvious upward trend in the whole process, whereas the fastest growth since 2012 was in hypertensive nephropathy. Conclusion: The proportion of SGD increased whereas PGD declined. IgAN remained the most common PGD, and HSPN was the most common SGD. MN and DN showed the most obvious upward trend among PGD and SGD, respectively. Changes in the spectrum of kidney disease, especially the constituent ratio of SGD, pose a great challenge to public health.

Objective:To explore the psychological experience and demand of parents of children with delayed recovery after congenital heart disease surgery.Methods:This study adopted phenomenological research methods from qualitative research. Using the purposive sampling method, parents of postoperative delayed recovery children with congenital heart disease who met the inclusion criteria were selected as the research objects from October to November 2019 at Fuwai Hospital, Chinese Academy of Medical Sciences. Semi-structured interviews were conducted with the parents of the children, and the data were analyzed by Colaizzi 7-step analysis method.Results:Finally, 13 parents of children with delayed recovery after congenital heart disease surgery were included. According to the interview results, four themes were extracted, which were negative psychological experience of parents of children with delayed recovery, positive psychological experience and expectation change of parents, heavy economic burden of parents and diversified needs of parents.Conclusions:During the delayed recovery period, psychological experience of parents is complex and their needs are diverse. The nursing staff should identify and pay attention to the causes of the negative psychological experience of the parents of the children, timely channel their negative emotions and strengthen the positive psychological experience in many aspects. They can assist parents to seek social help to reduce physical and mental pressure and meet the diverse needs of parents by providing high-quality nursing services and multi-channel information support.

Oropharyngeal carcinoma is a highly heterogeneous disease that is mainly caused by tobacco and alcohol abuse or high-risk human papillomavirus (HPV) infection. HPV-positive oropharyngeal carcinoma and HPV-negative oropharyngeal carcinoma have obvious differences in etiology, epidemiology and prognosis; therefore, different methods should be adopted for treatment. It is known that the TP53 gene is not mutated in HPV-positive oropharyngeal carcinoma, and radiation therapy can activate it and induce cell apoptosis via DNA damage. There are common repair pathways to DNA damage, such as nonhomologous end joining, and this pathway is more sensitive to radiotherapy under the inhibition of HPV oncoprotein. In addition, the further activation of the immune response under the effect of radiation also participates in the elimination of tumors. In this paper, we reviewed the research on the sensitivity of HPV-positive oropharyngeal cancer to radiotherapy to provide a scientific basis for targeted treatment for various pathogenic factors and clinical stages of oropharyngeal cancer in the future.

Objective: To investigate the feasibility of using a carbon dioxide(CO2) laser in the treatment of facial papilloma in children and to evaluate its curative effect and prognosis. Methods : A case of pediatric facial papilloma treated with a CO2 laser was reported, and the effects of this disease and CO2 laser treatment were reviewed and analyzed in combination with the literature. Results: Under general anesthesia, the lesion tissue of the left lip was excised for pathological biopsy, and the diagnosis was maxillofacial papilloma. The lesions were surgically ablated in stages with a CO2 laser, and erythromycin ointment was applied to the surgical incision after surgery. A total of three rounds of CO2 laser treatment were performed for 3 treatment courses. The child had no complications during or after the operation, the facial appearance was significantly improved, and there was no sign of recurrence during the 6-month follow-up. A literature review showed that CO2 lasers have been widely used in the excision of various surface lesions. In clinical practice, continuous CO2 laser with power of 10-50 W and wavelength of 10.6 μm is used to treat superficial tissue lesions, which can achieve accurate vaporization resection of diseased tissue, less bleeding and a good prognosis. Conclusion CO2 laser was accurate and minimally invasive for the removal of facial papilloma in children.
