Idiopathic membranous nephropathy(IMN) is one of the main pathology of nephrotic syndrome,and has a rising trend year by year.In recent years that IMN is organ specific autoimmune disease.Phospholipase A2 receptor(PLA2R) and thrombospondin type-1 domain containing 7A(THSD7A) are the two main antigens of IMN,which could be used to distinguish the IMN and secondary membranous nephropathy.The anti-PLA2R antibody and anti-THSD7A antibody are associated with diagnosis,severity and activity of the disease.The antibody titer and its change could be used to help deciding the beginning of therapy and the therapitive courses.

Objective To analyze the renal IgG subclasses in special patients whose renal HBsAg and HBcAg are positive, but plasma HBsAg, HBeAg, and HBcAg are negative.Methods Renal IgG subclasses were compared between 14 cases hepatitis-related nephropathy patients(diagnosed by renal biopsy pathology,whose blood hepatitis B antigens were negative) and 18 cases idiopathic membranous nephropathy patients.HBcAg and HBsAg were detected by indirect immunofluorescence assay, IgG, IgG1, 2, 3, 4 were stained by immunofluorescence.Results Renal IgG1-4 deposits were 100％ (14/14), 78.6％ (11/14), 78.6％ (11/14), 100％(14/14) separately in hepatitis B-related nephropathy group, and renal IgG1-4 deposits were 88.9％ (16/18), 5.6％ (1/18), 5.6％ (1/18), and 83.3％ (15/18) in idiopathic membranous nephropathy group.Renal IgG2 and IgG3 deposit more in hepatitis B-related nephropathy group than in idiopathic membranous nephropathy group (78.6％ vs 5.6％ ,78.6％ vs 5.6％;P =0.000) , but no significant difference in IgG1 and IgG4 deposit.Conclusion Renal IgG2 and IgG3 deposit more in hepatitis B-related nephropathy group than in idiopathic membranous nephropathy group, and may help some in diagnosis.

BACKGROUND: Carotid-femoral pulse wave velocity in hemodialysis patients is influenced by multiple factors.OBJECTIVE: To explore the carotid-femoral pulse wave velocity (PWVcf) changes and related factors in maintenance hemodialysis (MHD) patients.DESIGN, TIME AND SETTING: Non-randomized control experiment was performed at the Third Hospital of Peking University from January to August 2006.PARTICIPANTS: A total of 66 MHD patients were selected from Third Hospital of Peking University.METHODS: General clinical conditions, biochemical indexes, PWVcf and subjective nutritional state were evaluated. MHD patients were divided into two groups according to the state of nutrition evaluated with SGA: non-malnutrition (n=49), malnutrition group (n=17). The PWVcf of two groups was compared, and one-way and multiple regression analyses were performed to explore PWVcf-relatest factors.MAIN OUTCOME MEASURES: PWVcf, blood albumin and parathyroid hormone.RESULTS: PWVcf was significantly positively correlated with age (r= 0.284, P< 0.05), systolic blood pressure (r= 0.468, P<0. 001), and pulse pressure (r=0.451, P< 0.001), while negatively correlated with prealbumin (r=0.318, P< 0. 05),plasma-albumin (r=0.263, P< 0.05), parathyroid hormone (r=0.167, P< 0.05), serum creatinine (r=0.347, P= 0.004)and transferring (r=0.284, P < 0.05) before dialysis. Multiple regression analysis demonstrated that pulse pressure and parathyroid hormone were independently related with PWVcf. The PWVcf was significantly increased in malnutrition group compared with non-malnutrition group (P < 0.05). CONCLUSION: Pulse pressure is the major clinical determinants of arterial stiffness in patients with MHD independent of conventional risk factors for cardiovascular disease; Malnutrition and atherosclerosis are common complications of MHD,showing close relationship. The PWVcf was significantly increased in malnutrition patients.

BACKGROUND:Little data have been available concerning function features of arterial elasticity in patients with chronic kidney disease at 2-5 stage not undergoing dialysis.Studies have demonstrated that carotid-femoral pulse wave velocity(PWVcf) can be used to evaluate arterial elasticity.OBJECTIVE:To explore the changes and influential factors of PWVcf in patients with chronic kidney disease.DESIGN,TIME AND SETTING:A non-randomized controlled experiment was performed at the Department of Nephrology,Peking University Third Hospital from January to August 2006.PARTICIPANTS:166 patients with chronic kidney disease and 28 health persons were selected from Peking University Third Hospital.METHODS:The patients were divided into 3 groups based on the Kidney/Dialysis Outcomes Quality Initiative(K/DOQI) guideline for chronic kidney disease:mild group(at stage 1 to 2),moderate group(at stage 3) and severe group(at stage 4 to 5);the healthy people served as control.Body mass,blood pressure,PWVcf and biochemical indicators were determined to calculate glomerular filtration rate and compare the differences.One-way and multiple regression analyses were used to explore related factors of PWVcf.MAIN OUTCOME MEASURES:PWVcf and influential factors.RESULTS:Compared with control group,the patients had significantly higher levels of systolic blood pressure,diastolic blood pressure,pulse pressure and PWVcf(P

In recent years, more and more reports have been reported on the treatment of refractory primary membranous nephropathy with rituximab in bed, and its effect has been confirmed.A case of refractory primary membranous nephropathy was treated in the Department of Nephrology, Peking university Third Hospital.After the treatment of hormone combined with cyclophosphamide, cyclosporine and tacrolimus was ineffective, the patients were treated with low-dose rituximab for 2 years according to their condition, and the condition of the patients was finally relieved.

Objective To investigate the values of degree centrality (DC),a novel resting-state fMRI parameter,in voxel-wise whole-brain ftmctional networks analysis in patients with irritable bowel syndrome (IBS).Methods The resting-state functional MR imaging was performed in 21 IBS patients and 21 age-,education level-,and gender-matched normal healthy subjects,collected in our hospital from August 2013 to January 2015.DC map changes between the two patient groups were compared by two sample t test.Results As compared with the control group,patients with IBS showed significantly reduced DC values in right superior frontal gyrus,middle frontal gyrus,middle frontal gyrus of orbital part,middle temporal gyrus and precuneus.Conclusion Changes of DC value occurr in some regions of brain in the IBS patients;DC,as a novel resting-state functional MRI parameter in the voxel-wise whole-brain functional networks,might be an appealing altemative index for further studying on pathologic and neuropsychological states of IBS.

Guideline or consensus for the vaccination of children with special conditions like immunocompromised children may be more suitable for pediatricians.However, the vaccination of children in China is mainly performed by general practitioners or child health care practitioners in community health service centers.They need to master the screening knowledge of contraindications and precautions for the vaccination of children, and make the decision to referral to specialists.Based on the technical guidelines for Immunization of National Health Commission of the People′s Republic of China, Best Practices Guidance of the Advisory Committee on Immunization Practices and contraindications and precautions proposed by the Immunization Action Coalition, 20 suggestions for primary screening of children with vaccination contraindications and referral recommendations for primary care providers were developed by experts from the Integration of Medicine and Prevention in Children of Health Commission of Shenzhen Municipality.

Objective:To investigate the status quo of pain management for cancer patients in hospice care wards of community health service centers.Methods:The electronic medical records of 373 cancer patients admitted in hospice wards of Kangjian Community Health Center of Xuhui District and Jinshanwei Town Community Health Center of Jinshan District from January 2015 to July 2021 were collected. The characteristics of cancer pain, the use of analgesic drugs, the effects of analgesic drugs and its influencing factors were analyzed.Results:The incidence of cancer pain in 373 patients was 93.0% (347/373), and the proportion of moderate to severe cancer pain was 55.6% (193/347). Analgesics were used in 304 patients, among whom 233 (76.6%) patients used oral analgesics, 297 (97.7%) used on time, 97.6%(285/292) used sustained-release opioids, and 94 (30.9%) used combinedly. Breakout pain occurred in 100 cases (32.9%), all of which was controlled with immediate-release morphine. Cancer pain was not relieved in 132 cases (43.42%), and multivariate logistic regression analysis showed that the pain degree on admission (moderate: OR=3.69, 95 %CI:2.09-6.49; severe: OR=5.52, 95 %CI:2.43-12.53), the presence of burst pain ( OR=3.28, 95 %CI:1.77-6.06), the type of analgesics used (non-steroidal+weak opioids: OR=0.39, 95 %CI:0.20-0.76; nonsteroidal+strong opioids: OR=0.20, 95 %CI:0.08-0.51) and the adverse reactions ( OR=1.92, 95 %CI:1.03-3.60) were the influencing factors of pain relief in cancer pain patients (all P<0.05). Conclusion:The pain of cancer patients admitted to community palliative care wards cannot be ignored. Although most cancer pain patients use analgesic drugs in a standard way, there are still a high proportion of patients whose pain is not controlled. Various factors affect the effect of analgesic treatment.
