Objective To explore the clinical characteristic,level of plasma renin angiotensin (PRA),plas-ma angiotensin Ⅱ(Ang Ⅱ)and plasma aldosterone(Aldo)in the sleep apnea hypopnea syndrome (SAHS)patients, and to investigate the association between SAHS and hypertension.Methods The patients were selected for the study who were monitored with polysomnography.They were divided into SAHS group and non-SAHS group according to apea-hypopnea index(AHI),and there were 180 patients in the SAHS group,175 patients in the non-SAHS group. The systolic blood pressure(SBP),diastolic blood pressure(DBP)and the level of PRA,plasma Ang II and plasma Aldo were compared by variance analysis.Results The gender composition was different between the two groups,and had statistically significant difference(χ2 =16.30,P <0.01).The data of age,body mass index,neck circumference, waistline,DBP,SBP in SAHS group were significantly higher than those in non-SAHS group,and the differences were statistically significant(t =6.84,8.19,9.84,6.63,7.08,5.45,all P <0.01 ).The prevalence of hypertension in SAHS group was 46.58%,which was higher than 18.20% in non-SAHS group,and the difference had statistically significant(χ2 =46.71,P <0.01).The AHI had positive correlation with SBP,DBP,and they had statistically signifi-cant differences (rs =0.162,0.228,all P <0.01).The levels of PRA and plasma Ang Ⅱ were lower in SAHS group than those in non-SAHS group,while the level of plasma Aldo was higher in SAHS group than that in non-SAHS group,and had statistically significant differences(F =15.41,14.21,17.67,all P <0.01).In the SAHS group,the levels of PRA and plasma Ang Ⅱ were lower in hypertension group than those in non-hypertension group,while the level of plasma Aldo was higher in hypertension group than that in non-hypertension group,and had statistically signif-icant differences (F =15.41,14.21,17.67,all P <0.01).Also,the levels of PRA and plasma Ang Ⅱ were lower in SAHS group with hypertension than those in non-SAHS group with hypertension,while the level of plasma Aldo was higher in SAHS group with hypertension than that in non-SAHS group with hypertension,and the differences were sta-tistically significant(F =15.41,14.21,17.67,all P <0.01).Conclusion The occurrence of SAHS is correlated with the gender composition,age,body mass index,neck circumference,waistline,DBP and SBP.In SAHS complica-tions in each system,the highest incidence is hypertension.And the AHI has positive correlation with SBP,DBP,and the difference is significant.In the SAHS group,if the AHI is higher,the risk of hypertension is greater.In the SAHS patients with hypertension,the level of plasma Aldo is significantly elevated,while the levels of PRA and plasma AngⅡ are decreased significantly.

A case of varicella pneumonia, hepatitis and pancreatitis after kidney transplantation was retrospectively analyzed. One week after kidney transplantation, the patient had a papule with pruritus, which was diagnosed as varicella by dermatologist as well as high-throughput sequencing. The patient was found to have pneumonia, hepatitis and pancreatitis. The individualized treatment regimen was used, including the dosage reduction of immunosuppressive agents, the blood drug concentration monitoring, antiviral therapy, anti-infection therapy, supportive treatment, and symptomatic alleviation for complications. The treatment was adjusted according to the indicators'variation. The timely review of the indicators and immunosuppressant blood concentration were performed to protect the transplanted kidney function, and the patient recovered in time. This rare case of postoperative complications of kidney transplantation were summarized and analyzed in order to accumulate clinical experience for the treatment of renal transplantation.

Objective To explore the prevalence of the nuclear dense fine speckled ( DFS ) immunofluorescence pattern in routine antinuclear antibodies(ANA) testing and its significance in patients with autoimmune diseases( AID) .Methods The ANA in 13 728 specimens were measured by indirect immunofluorescence( IIF) using HEp-2 cell slides from department of clinical laboratory, wenling hospital from 2011 to 2014.The frequencies, clinical manifestations and laboratory features of DFS positivity were restrospectively analyzed in patients with AID,usingχ2 test.Results ANA was positive in 20.56%(2 822/13 728) of the total patients, and the frequency of DFS pattern was observed in 1.81%(248/13 728) of the total patients and in 8.79%(248/2 822) of the patients with ANA positivity.In different age groups (≤20 years old, 21-49 years old and≥50 years old) , there were statistical significance of DFS pattern positive rate (male:χ2 =18.17,P<0.01; female: χ2 =1 500.00,P<0.01).And the highest frequency of ANA positivity was observed in patients from department of rheumatology(30.07%).The frequency of DFS pattern was higher in the departments of infection ( 32.58%) , dermatology ( 21.76%) , neurology ( 18.58%) and nephrology(6.73%) among the patients with ANA positivity(χ2 =123.00,P<0.01).Amony the 248 cases with DFS pattern positivity.41 cases were AID ( 16.53%) and 207 cases were non-autoimmune diseases ( 83.47%) . In AID group 13 cases were autoimmune thyroiditis ( 31.71%) , 12 cases were rheumatoid arthritis ( 29.27%) , 4 cases were autoimmune liver disease ( 9.76%) , 4 cases were undifferentiated connective tissue disease (9.76%), 3 cases were ankylosing spondylitis(7.32%), 2 cases were Sj?gren′s disease ( 4.88%) , 2 cases were inflammatory bowel disease ( 4.88%) and 1 case was systemic lupus erythematosus(2.44%).The titers of DFS in patients with AID were predominantly above 1∶320 and less than 1∶100 in non-AID.AID patients with DFS pattern positivity have different clinical manifestations and laboratory features.Howerer, antinuclear antibodies ( ANAs ) in 15 specific auto-antibodies were all negative.Conclusions The DFS pattern is a common pattern in ANA positivity patients and it mainly exists in non-AID patients.Further more, it is suggested that patients with DFS pattern identified by IIF should then be tested for anti-DFS70 antibodies with a specific immunoassay.

Objective To explore the prevalence of the anti-saccharomyces cerevisiae antibody (ASCA) in patients with primary biliary cirrhosis and evaluate it's clinical significance. Methods The subtypes of ASCA including IgA and IgG in blood samples from 162 patients with PBC, 44 patients with AIH,4-1 patients with other non-autoimmune liver diseases controls (LDC), 144 patients with inflammatory bowel disease (IBD) and 35 healthy controls were measured by ELISA. Chi-square test and Mann Whitney U test were used for statistical analysis. Results The positive rate of ASCA-IgA in PBC was 24.1%, which was higher than that in ulcerative colitis (UC) group ( 11.6%,χ2=5.5, P＜0.05 ) and healthy controls (0, χ2=10.5,P＜0.01 ). Compared with the AIH group (20.5%) or LDC group ( 14.6% ) or Crohn's disease (CD) (34.5%),there was no statistically significant difference (P＞0.05). The prevalence of ASCA-IgG in PBC was 11.1%,lower than the CD group (27.6%, χ2=8.9, P＜0.01 ), but higher than that in the healthy controls (0, χ2=10.5,P＜0.01 ). There was no statistically significant difference (P＞0.05) between PBC and the AIH group (15.9%)or LDC group (7.3%) or UC group (8.1% ). The positive rate of both ASCA-IgA and ASCA-IgG in PBC was only 6.2%, statistically lower than that of the CD group ( 17.2%, χ2=6.3, P＜0.05). The prevalence of ASCA-IgA or ASCA-IgG in PBC was 29.0%, which was statistically lower than that of the CD group (44.8%, χ2=4.8,P＜0.05), but higher than that of the UC group (χ2=5.9, P＜0.05) or healthy controls (χ2=13.3, P＜0.01).ASCA was detected more frequently in PBC patients with positive anti-GP210 antibody than in anti-GP210 antibody negative PBC patients (38.6% vs 23.8%,χ2=3.9, P＜0.05). The positive rate of ASCA between AMA positive and negative patients with PBC or anti-SP100 antibodies positive and negative patients with PBC was not significantly different. PBC patients with positive ASCA-IgA had higher level of TBIL, DBIL, TBA, LD,IgA, IgM, ESR and lower level of ALB, A/G, CHE than patients with negative ASCA-IgA. There was no statistically significant difference in liver injury indicators and immune function parameters between patients with positive ASCA-IgG and negative ASCA-IgG. Conclusion ASCA is not an IBD-specific antibody. There is a high prevalence of ASCA in patients with PBC, especially the subtype of ASCA-IgA. ASCA-IgA is found to be associated with the severity of liver damage and immune activity whereas ASCA-IgG is not associated with them.

Objective To summarize the experience with cadaveric renal transplantation for improving the long-term survival rate of the recipients.Methods The clinical data of 1210 cases(773 men and 437 women;age range,6-75 years) of cadaveric kidney transplantation from 1986 to 2003 were analyzed retrospectively,including the resection of the donor's kidneys,surgical techniques,use of immunosuppressants,and complications.The 1210 patients underwent renal transplantation for most of them(1047 cases) suffered from chronic glomerulonephritis.Lymphocytotoxicity test was performed in 1210 cases with all

Objective:To investigate the value of cystatin C (Cys-C) in the early diagnosis of acute kidney injury (AKI) after radical nephrectomy and the predictive value for the prognosis of Cys-C based estimated glomerular filtration rate (eGFR Cys-C) after surgery. Methods:The clinical data of 118 patients who underwent unilateral radical nephrectomy in our hospital from January 2019 to December 2020 were retrospectively analyzed. According to the diagnostic criteria of AKI, they were divided into AKI group of 75 cases and no-AKI group of 43 cases. AKI group was (62.7±10.7) years old, with 49 males and 26 females. The no-AKI group was (62.3±12.8) years old, with 21 males and 22 females. The urea nitrogen was (4.9±1.3) mmol/L, creatinine (75.7±14.5)μmol/L, Cys-C (0.85±0.22) mg/L, eGFR Cr(76.3±11.2)ml/(min·1.73m 2), and eGFR Cys-C(101.4±17.4)ml/(min·1.73m 2)in AKI group before operation.In no-AKI group, preoperative urea nitrogen was (4.9±1.5) mmol/L, creatinine (74.5±13.1)μmol/L, Cys-C (0.81±0.29) mg/L, eGFR Cr(78.6±12.5)ml/(min·1.73m 2), and eGFR Cys-C(99.3±18.8)ml/(min·1.73m 2), and there were no significant differences in the values of urea nitrogen, creatinine, Cys-C and eGFR between the two groups before surgery ( P>0.05). ROC curve was used to analyze the diagnostic value of urea nitrogen, creatinine, Cys-C, eGFR calculated based on creatinine and Cys-C at 48h after surgery, and binary Logistic regression was used to analyze the risk factors for AKI. The creatinine status of patients diagnosed with SPS was evaluated 6 months after surgery, based on the definition of Cys-C based eGFR being less than 70% of creatinine-based eGFR(SPS=eGFR Cys-C/ eGFR Cr≤0.7). Results:In AKI group, creatinine was(115.2±22.1)μumol/L, Cys-C (1.8±0.27) mg/L, eGFR Cr (51.6±9.6)ml/(min·1.73m 2), and eGFR Cys-C(43.4±8.5)ml/(min·1.73m 2)48 h after operation. The creatinine was(92.7±13.3)μmol/L, Cys-C(1.3±0.23) mg/L, eGFR Cr(62.2±11.3)ml/(min·1.73m 2), and eGFR Cys-C(61.5±9.5)ml/(min·1.73m 2) in no-AKI group, and difference were statistically significant between the two groups ( P<0.01). ROC curve was used to analyze the diagnosis of AKI. Creatinine, Cys-C, eGFR Cr and eGFR Cys-Cwere all of diagnostic value for AKI (all P<0.01), and AUC(Area under curve) were 0.809, 0.889, 0.761 and 0.925 respectively. The sensitivity, specificity and area under the curve of eGFR Cys-C were 93.3%, 74.4% and 92.5% respectively. Binary Logistic regression analysis showed that creatinine( OR=10.851, 95% CI 2.322-50.688, P=0.004), Cys-C( OR=10.016, 95% CI 2.306-43.362, P=0.001), eGFR Cr( OR=17.923, 95%CI 3.216-53.172, P=0.001) and eGFR Cys-C( OR=19.817, 95% CI 3.367-55.263, P=0.001)were all independent risk factors for AKI. The predictive accuracy of eGFR Cys-C, creatinine, Cys-C, eGFR Cr were 91.6%, 85.7%, 90.2%, 88.5%, respectively. There were 15 cases were confirmed SPS in the AKI group, and only 2 cases were confirmed SPS in the no-AKI group, indicating patients in the AKI group developed more SPS than those in the no-AKI group, with statistically significant difference(Kappa value was 5.22, P=0.02). The 6-month follow-up showed that the creatinine of confirmed SPS was (103.8±23.4)μmol/L and the creatinine of unconfirmed SPS was (86.8±27.2)μmol/L, with statistically significant difference ( P<0.01). Conclusions:eGFR Cys-C calculated based on Cys-C has high sensitivity in diagnosing AKI and has early diagnostic value. Patients diagnosed with SPS based on eGFR Cys-C had higher creatinine 6 months after surgery.
