【Objective】 To investigate the status quo of disease perception and partner support of erectile dysfunction (ED) patients, and to analyze their correlation. 【Methods】 With convenient sampling method, 220 ED patients in a first-class hospital in Taiyuan were surveyed with the short version of disease perception questionnaire (BIPQ) and partner support coping questionnaire (DCI). 【Results】 The BIPQ score was (41.90±7.33), and the DCI score was (116.79±20.37). Pearson correlation analysis showed that except life influence, treatment control and emotional influence, the mutual support dimension of partner support of ED patients was correlated with all dimensions of disease perception (r=-0.173, 0.151, -0.182, 0.163, 0.188,P<0.05).Except cognitive comprehension, the negative support dimension of partner support of ED patients was correlated with the dimensions and total score of disease perception (r=0.399, 0.185, -0.167, -0.306, 0.269, 0.445, 0.320, 0.357,P<0.05). 【Conclusion】 ED patients have negative disease perception, and their partners have better coping strategies. Medical staff may pay more attention to partner support so as to reduce patients’ negative perception of disease and promote recovery.

Objective To investigate the effects of the rhein on the mitochondria fission and epithelial-mesenchymal transition(EMT)of breast cancer cells MDA-MB-231.Methods Human breast cancer cells were intervened with rhein,and the cells were divided into control group(0 μmol·L-1),low dose rhein group(100 μmol·L-1),and high dose rhein group(200 μmol·L-1).The proliferation activity of the cells was detected by CCK-8,and migrations was detected by Scratch-healing migration assay.The morphology and distribution of mitochondria were detected by transmission electron microscope,and the expression levels of Dynamin-related protein 1(Drp1),mitofusin2(Mfn2),E-cadherin,Vimentin proteins were detected by Western blot.Results Compared with control group,Rhein significantly reduced the protein expression of Drp1、Vimentin(P<0.05),and increased E-cadherin and Mfn2,thus down-regulating mitochondria fission,inhibiting cell proliferation and migration.High dose Rhein was better than low dose.Conclusion Rhein can inhibit the proliferation and migration of breast cancer cells by reducing the expression of Drp1,Vimentin and up-regulating Mfn2,E-cadherin proteins.

Objective:To evaluate the long-term efficacy of laparoscopic-assisted natural orifice specimen extraction surgery (NOSES) colectomy using Cai tube for treating left-sided colorectal cancer.Methods:This was a randomized controlled trial. Inclusion criteria were as follows: preoperative pathological diagnosis of left-sided colorectal adenocarcinoma (rectal, sigmoid colon, descending colon, or left transverse colon cancer with the caudad margin ≥8 cm from the anal margin); preoperative abdominal and pelvic computed tomography (or magnetic resonance imaging) showing maximum tumor diameter <4.5 cm; and BMI <30 kg/m 2. Patients with synchronous multiple primary cancers or recurrent cancers, a history of neoadjuvant chemoradiotherapy, preoperative evidence of significant local infiltration, distant metastasis, or complications such as intestinal obstruction and intestinal perforation, or who were not otherwise considered suitable for laparoscopic surgery were excluded. A random number table was used to randomize sequential patients to NOSES surgery using Cai tube (non-assisted incision anal sleeve: patent number ZL201410168748.2) (NOSES group) or traditional laparoscopic-assisted surgery (CLS group). Relevant clinical data of the two groups of patients were analyzed, the main outcomes being disease-free survival, overall survival, overall recurrence rate, and local recurrence rate 5 years after surgery. Results:Patients in both study groups completed the surgery successfully with no requirement for additional surgery. After mean 70 (7–83) months postoperative follow-up, the 5-year overall postoperative survival in the NOSES and CLS groups was 90.0% and 83.3%, respectively ( P=0.455); disease free survival was 90.0% and 83.3%, respectively ( P=0.455); overall recurrence rate 6.6% and 10.0%, respectively ( P=0.625); and local recurrence rate both were 3.3% ( P=0.990), respectively. None of these differences was statistically significant. Conclusions:NOSES and CLS have similar long-term efficacy, and NOSES deserves to be used in clinical practice.

Objective:To investigate the clinicopathologic characteristics, treatments, outcomes and mechanisms of hemolytic uremic syndrome (HUS) complicated with IgA nephropathy (IgAN).Methods:The clinical manifestations, treatments, prognosis and histopathological features of renal biopsy tissues were analyzed in two cases of HUS complicated with IgAN from Beijing Children′s Hospital, Capital Medical University using light microscopy, immunofluorescence detection and electron microscopy. The related literatures were also reviewed.Results:The clinical manifestations were microvascular hemolytic anemia, thrombocytopenia, acute renal impairment with hematuria, proteinuria, and positive anti-H factor antibody. Histological findings confirmed presence of both HUS and IgAN. Histological features included glomerular mesangial and stromal hyperplasia with endothelial cell proliferation, capillary stenosis, arteriolar thickening, and glomerular ischemia and capillary dilatation. Immunofluorescence detection showed diffuse IgA deposition in the glomerular mesangial matrix. Electron microscopy showed proliferation of mesangial and endothelial cells, thickening of the inner layer of the glomerular basement membrane, deposition of massive electronic densification in the mesangial region, and shrinkage of the segmental basement membrane. The two children were very responsive to plasma exchange and steroid treatments. However, their urine protein and occult blood tests remained continuously positive during the follow-up of 5 years 7 months and 8 months respectively.Conclusions:HUS complicated with IgAN is rare. The diagnosis relies on various pathological examinations, which require the combination of light microscopy, immunofluorescence detection and electron microscopy. Plasma exchange and steroid treatments are effective. However, the long-term prognosis is concerning and may relate to pathological grade and secondary factors. The mechanism of connecting HUS and IgAN is unknown, but may be caused by prodromal or secondary factors.

Since January 2020, as ophthalmologists working at the center of the novel coronavirus pneumonia (NCP) outbreak in Wuhan, China, we found 3 cases in 30 NCP patients with binocular conjunctivitis. Of them, one case visited for conjunctivitis as a first symptom and then diagnosed as NCP, and two cases visited for binocular conjunctivitis during the NCP onset. In 3 patients, conjunctivitis was manifested as signs of viral conjunctivitis from mild to moderate. Their symptoms of two patients disappeared after treatment with antiviral eyedrops for 7 to 10 days and another patient died of NCP. Interestingly,although we detected positive viral nucleic acid in the conjunctiva sacs of 2 of other 27 NCP patients by using swabs and RT-PCR technology, no conjunctivitis occurred in these two patients.

Objective: To analyze the Oxford classification (MESTC) and the International Study of Kidney Disease in Children (ISKDC) classification for evaluating the clinical manifestations, histological lesion and short-term prognosis of children with Henoch-Schönlein purpura nephritis (HSPN). Methods: According to the Oxford classification and ISKDC classification, the histological lesions of children with HSPN diagnosed by renal biopsy from Beijing Children's Hospital affiliated to Capital Medical University from January 2018 to December 2018 were re-evaluated. The renal biopsy specimens of the selected subjects were scored according to the Oxford classification and the ISKDC classification. According to whether the first symptom was combined with renal performance, MESTC score and ISKDC classification, children were grouped. The differences in clinicopathological manifestations between the groups were compared. Correlation between MESTC and ISKDC grades was analyzed by nonparametric test rank correlation. Kaplan-Meier survival curve and Log-rank test were used to compare the difference of proteinuria remission rate between the two groups. Univariate and multivariate Cox regression equations were used to analyze the influencing factors of the proteinuria remission rate. Results: A total of 78 children with HSPN were enrolled. There were 37 male patients (47.4%) with age of (10.4±2.9) years. When the patients were divided according to MESTC scores and ISKDC classification, the results showed that the proportion of children with nephrotic-range proteinuria in the group of endocapillary hypercellularity (E1, P=0.008), segmental glomerulosclerosis (S1, P=0.015) and ISKDCⅢ(P=0.041) was higher than that of E0, S0 and ISKDCⅡ groups. The proportion of children with E1 (P=0.015), crescents (C1&C2, P=0.025) or ISKDCⅢ(P=0.017) that had been treated with high-dose methylprednisolone was higher. The result of Kaplan-Meier survival curve showed more difficult for proteinuria remission in children with C2 are than C0&C1 group (P=0.026), while no difference were found when children were grouped by M, E, S, T and ISKDC. Multivariate Cox regression analysis showed that the C2 (HR=0.143, 95%CI 0.020-1.046, P=0.055) might be a risk factor for proteinuria remission, while the P value was close to 0.05. Conclusions Children with HSPN scored as ISKDCⅢ, E1 and S1 are more likely to show nephrotic-range proteinuria. C2 may indicate that patients are more difficult to achieve proteinuria remission.
