Objective To compare the one?year survival rates of maintenance hemodialysis (HD) patients with different quality of life, and analyze related factors affecting the prognosis of patients. Methods Patients on hemodialysis for at least 3 months were enrolled. A short form 36 health survey questionnaire (SF?36) and Pittsburgh sleep quality index (PSQI) were used to evaluate the quality of life and quality of sleep. To observe one?year all?cause mortality and Cox regression model was used to analyze the factors associated with survival outcomes. Results A total of 159 patients undergoing hemodialysis were included, in which 136 patients completed the follow?up after one?year observation. The one?year survival rate in patients with both high physical component summary (PCS) and mental component summary (MCS) scores was significantly better than the patients with low PCS and MCS scores (P﹤0.05). PCS, hemoglobin and serum albumin were the protection factors for HD patients. Conclusions Quality of life is strongly associated with prognosis in HD patients. Enhancing quality of life is of clinical significance in the improvement of HD patients' survival rate.

Objective To enhance the understanding of cystitis, obstructive uropathy (OU) and chronic intestinal pseudo-obstruction (CIPO) in systemic lupus erythematosus (SLE). Methods We presented a case of SLE complicated with cystitis, OU and CIPO, and reviewed relevant English and Chinese literature. Results The case was a 37 year-old female with a history of SLE for 4 years. She developed urinary irritant symptoms for 1 year and abdominal distention for 1 month before admission. Ultrasound and cystoscopic studies revealed a thickening of bladder wall and reduced bladder volume; cystoscopic study revealed inflammatory and edematours mucosa; Ultrasound study and X-ray image confirmed the existence of OU and CIPO. Symptoms of urinary irritant and CIPO were relieved after initiation of prednisone and cyclophosphamide (CTX), but reducing the dosage of prednisone and CTX had caused a relapse. Conclusion Cystitis is a rare clinical manifestation of SLE, it is likely to be misdiagnosed. The pathological change of cystitis complicated with SLE is interstitial cystitis and is the most common cause of OU in SLE. OU is closely related to CIPO and it is suggested that patients with these complications may be classified as a unique subgroup of SLE. Intestinal obstruction is a severe complication of SLE with high mortality rate, clinicians should be aware of this unique subgroup of SLE and treat it properly.

Objective To study the clinical effect and application value of micro-plasma beam joint radiofrequency treatment for the striae of pregnancy.Methods 21 female patients with the striae of pregnancy were included in this study,treated from the July 2012 to March 2014,aged 25-37 years;and time of the striae was from 3 months to 7 years.Micro-plasma radiofrequency technology was used to treat the striae,with interval of 30 days each time for total seven months.The total effective rate,satisfaction,and the adverse reaction were evaluated after the treatment.Results 21 patients included grade 4 in 6 cases,grade 6 in 10 cases,grade 2 in 4 cases and grade 1 in 1 case;the total effective rate was 95.2％ (20/21).Satisfactory degree was for the level C in 6 cases,B in 14 cases,and A in 1 case,with total satisfactory rate of 95.2％ (20/21).Adverse reactions included mild pigmentation in 2 patients after scab skin falling off,and disappeared at the end of the treatment course.Conclusions Micro-plasma beam combined with radio frequency in treating the striae of pregnancy has clear curative effect and good clinical application value.

Objective To compare the therapeutic effect of dark plum mixture on rats with radiation-induced xerostomia, given by gastric gavage and oral spray. Methods Rat model of radiation-induced xerostomia were developed by electron linear accelerator. Wistar rats were randomly divided into spray group and gastric gavage group, and normal group, positive control group and normal control group were set up within these two groups. The dark plum mixture was administered for 14 days. After treated for 7 days and 14 days, saliva was collected and submandibular gland samples were collected. The salivary secretion, Sorgan index, component analysis and pathological changes of submaxillary glands between the groups were assessed. Results On the 7thday after irradiation, the saliva secretion and gland coefficient of the dark plum spray group were significantly higher than the positive control group and normal control group (P＜ 0. 05). The saliva secretion, gland coefficient and saliva amylase activity of the dark plum mixture spray group were significantly higher than the dark plum mixture gastric gavage group (P＜ 0. 05). On the 14th day after irradiation, the saliva secretion and gland coefficient of the oral spray group were significantly higher than the gastric gavage group (P ＜ 0. 05 ). The pathological examination of submandibular gland tissues showed that 7 days after irradiation, there were less interglandular space and inflammatory cell infiltration in the oral spray group than the gastric gavage group. On the 14th day after irradiation, the ductal damage and cell nuclear pyknosis in the oral spray group were milder than the gastric gavage group. Vacuolated necrosis and nuclear pyknosis of some glandular cells were visible in the gastric gavage group 7 and 14 days after irradiation. Conclusions Compared with gastric gavage, the oral spray of dark plum mixture increases more saliva and salivary α-amylase secretion, effectively promote the repair of submandibular glandular cells after salivary gland irradiation, and indicates a better therapeutic effect on radiation-induced xerostomia.

Objective To compare the influence of hemodialysis (HD) and peritoneal dialysis (PD) on early outcome of patients underwent kidney transplantation from donation after cardiac death (DCD).Methods Patients admitted in the First People's Hospital of Foshan with DCD kidney transplant from January 1st,2011 to June 30th,2016 were analyzed retrospectively.Recipients were grouped into HD group (n=61) and PD group (n=28) according to their pre-transplant dialysis modality.Their short-term outcomes after DCD kidney transplant were compared,including recovery of renal function,short-term complications and laboratory data.Results Patients had longer dialysis duration and lower hemoglobin,serum albumin and phosphorus in PD group than those in HD group (all P ＜ 0.05),but no significant difference shown in age,gender,body mass index,primary disease,blood pressure,and hepatitis B infection (all P ＞ 0.05).HD patients with 6.00(4.00,11.00) d recovery time of renal function,18.00(17.00,21.50) d hospital time,had 24.59％ the delayed graft function (DGF),3.28％ acute rejection and 16.39％ infection during hospitalization.While for PD patients the recovery time of renal function was 4.00(3.75,7.00) d;hospital time was 19.00(15.00,21.75) d;the incidence rate of DGF was 14.29％;acute rejection was 3.57％;and infection during hospitalization reached 17.86％.Above indexes were not significantly different between HD and PD groups (all P ＞0.05).Repeated measure ments showed that,compared with those before transplant surgery,after 1 month,3 months and 6 months HD and PD groups had decreased creatinine and phosphorus,and increased hemoglobinserum albumin and calcium;Serum albumin and calcium were different between the two groups (P ＜ 0.001,P=0.040),whereas creatinine,hemoglobin and phosphorus did not show difference (all P ＜ 0.05).After transplantation the trends of creatinine,hemoglobin,calcium and phosphorus were not different between the two groups (P values were 0.295,0.310,0.501 and 0.063,respectively).Conclusions No significant difference of the recovery regarding renal function,anemia,nutrition status and mineral metabolites was found between pre-transplant HD and PD modality in patients who underwent DCD kidney transplantations.

Objective To observe the short?term clinical outcomes of kidney transplantation from brain and cardiac death donors (DBCD) and assess its feasibility to expand organ donor pool. Methods A retrospective analysis was performed on 48 cases of kidney transplantation from DBCD. The transplant recipients had finished 12?month follow?up in the First People's Hospital of Foshan from September 2011 to February 2015, with their renal function, rejection reaction and complications at 1 week, 1 month, 3 months, 6 months and 12 months after renal transplantation being collected. Survival rates of transplant recipients and transplant kidneys, incidence of delayed graft function (DGF) and its influence for recipients and graft survival were analyzed by statistics. Results In the 48 cases, the survival rates of recipients at 1, 3, 6 and 12 months after transplantation were 100.0%, 100.0%, 97.9%, 95.8%, and the survival rates of transplanted kidneys were 95.8%, 95.8%, 93.8%, 91.7%, respectively. DGF occurred in 8 of 48 (17.0%), but the occurrence of DGF did not adversely influence patient's survival (P=0.524) or graft survival (P=0.362). Conclusions The short?term clinical outcomes of kidney transplantation from DBCD are ideal. As the legislation of donation after brain death (DBD) has not been ratified in China, the kidney transplantation from DBCD could be an
important way to solve the shortage of organs, and increase the number of kidneys available for transplantation.

Objective: To find out the prognostic influencing factors of patients undergoing continuous renal replacement therapy (CRRT) for refractory acute left heart failure. Methods: Through the medical system and hemodialysis system in Foshan First People's Hospital, all patients who received CRRT for refractory acute left ventricular heart failure from January 1, 2012 to January 1, 2019 were searched. All patients were divided into two groups by the final outcome: survival group and death group. Age, sex, initial mean arterial pressure (MAP), primary heart disease, use of vasoactive drugs, urine output before treatment, hemoglobin, serum creatinine, serum albumin, C-reactive protein(CRP), brain natriuretic peptide (BNP), cardiac ejection fraction (EF) and CRRT treatment time were analyzed to find out the prognostic influencing factors. Results: A total of 130 cases were collected, including 96 cases in the survival group and 34 cases in the death group, with a total mortality rate of 26.15%. Compared to that in the death group, there were higher proportion of males (71.88% vs 50.00%, χ²=5.366, P=0.021), significantly higher initial MAP (t=4.677, P<0.001), much more urine output before treatment (Z=3.904, P<0.001), significantly higher serum creatinine (Z=2.866, P=0.004) , significantly lower hemoglobin (Z=-2.587, P=0.011), significantly shorter time of CRRT (Z=-3.447, P=0.001) in the survival group. Multivariate logistic regression analysis showed that female (OR=2.950, 95%CI 1.102-7.898, P=0.031) and higher levels of hemoglobin (OR=1.024, 95%CI 1.004-1.045, P=0.019) were the risk factors of death in patients undergoing CRRT for refractory acute left heart failure, while higher levels of mean arterial pressure before treatment (OR=0.959, 95%CI 0.930-0.989, P=0.008) and urine volume before treatment (OR=0.998, 95%CI 0.997-0.999, P=0.004) were the protective factors for patients' prognosis. Conclusion The mortality of patients with refractory acute left heart failure undergoing CRRT therapy is still very high. Female and higher level of hemoglobin are the risk factors for death, while more urine volume before treatment and higher MAP before treatment are protective factors for survival.

Objective To investigate the clinical efficacy of renal transplantation from donors of donation after brain and cardiac death(DBCD) complicated with acute kidney injury (AKI),and summarize the clinical experience of evaluation and application.Methods The clinical data of the 45 DBCD donors and 80 recipients in the First People's Hospital of Foshan from September 2011 to September 2015 were retrospectively analyzed.DBCD donors were classified into the AKI group (n=26) and non-AKI group (n=19) according to the serum creatinine level and urine output when the donors were admitted to the intensive care unit (ICU) in this hospital.A total of 80 recipients were divided into the AKI group (n=46) and non-AKI group (n=34) correspondingly.The condition of the donors before organ procurement between the two groups was compared,and the incidence of various complications,the 1 years survival rates of recipients and graft after renal transplantation were compared between the two groups.Results Among 45 donors,26 cases(57.8％) suffered from AKI.The serum creatinine of donors was significantly higher in the AKI group than that in the non-AKI group (P ＜ 0.01).The incidence of delayed graft function (DGF) in AKI group and non-AKI group was 21.7％ and 8.8％ respectively (P ＞ 0.05).After 1 years,the serum creatinine of the recipients in AKI group was significantly higher than that in non-AKI group [(134.9±63.4) μmol/L vs (106.6±28.2) μmol/L,P＜ 0.05],but the survival rates of recipients and grafts did no differ between the two groups (both P ＞ 0.05).Conclusions The donors combined with AKI do nothave a worse effect on the incidence of DGF,the 1-year survival rates of recipients and grafts after transplantation.So,the donors with AKI for transplantation can widen the origin of kidney grafts.

Objective To investigate the relationship between serum uric acid level and renal function decline by retrospective cohort study.Methods Through the physical examination system of the First People's Hospital of Foshan,the physical examination data from 2015 to 2018 of a public institution in Foshan city were obtained.The gender,age,blood cell analysis,liver function,serum creatinine,uric acid,fasting blood glucose were obtained.The change of eGFR (△eGFR=eGFR2018-eGFR2015) was analyzed.Results A total of 2505 subjects were followed up for four years.The subjects were divided into △eGFR ≥0 group and △eGFR ＜ 0 group.There were 845 subjects in △eGFR ≥0 group,and 1660 subjects in △eGFR ＜ 0 group.Compared with that in △eGFR ＜ 0 group,the base-level of uric acid in △eGFR ≥ 0 group was higher [(349.48±87.62) μmol/L vs (325.72±82.58) μmol/L,t=6.669,P ＜ 0.001],but the rate of uric acid decline was greater [-15.00(-53.50,17.00) μmol/L vs 15.50(-18.00,49.00) μmol/L,Z=-13.470,P ＜ 0.001].According to the levels of uric acid in 2015 and 2018,then the subjects were divided into four groups,normal to normal group (N-N,1551 cases),normal change into high uric acid group (N-H,299 cases),high uric acid drop to normal group (H-N,238 cases),and high to high uric acid group (H-H,417 cases).The △eGFR was-1.58(-4.17,1.01) ml · min-1 · (1.73 m2) 1 in N-N group,and-3.60(-7.24,-0.98) ml · min-1 · (1.73 m2)-1 in N-H group,-0.20(-3.14,3.27) ml· min-1· (1.73 m2)-1 in H-N group,-0.96(-4.07,1.93) ml· min-1· (1.73 m2)-1 in H-H group,respectively.The △eGFR decreased most significantly in N-H group than the other three groups (x2=103.130,P ＜ 0.001).Multivariate logistic regression analysis showed that elevated uric acid was an independent risk factor for eGFR decline (OR=1.739,95％CI 1.587-1.906,P ＜ 0.001),while elevated indirect bilirubin (OR=0.968,95％CI 0.943-0.993,P=0.013),elevated red blood cells (OR=0.815,95％ CI 0.680-0.976,P=0.026) were independent protective factors for eGFR decline.Conclusion Elevated uric acid is an independent risk factor for the decline of renal function.Good control of hyperuricemia is beneficial to the protection of renal function.

Objective:To compare the survival rate of secondary hyperparathyroidism (SHPT) patients with different dialysis modalities after parathyroidectomy (PTX), and analyze the influencing factors of survival prognosis.Methods:Clinical data of dialysis patients diagnosed with SHPT and treated with PTX in the First People′s Hospital of Foshan from April 2014 to May 2019 were retrospectively collected and analyzed. The patients were divided into hemodialysis (HD) group and peritoneal dialysis (PD) group according to preoperative dialysis modalities, and the differences in baseline clinical data and cardiac ultrasound results were compared between the two groups. Kaplan-Meier survival analysis was used to compare the difference in cumulative survival rate between the two groups. Multivariate Cox regression model was used to analyze the influencing factors of all-cause death. Receiver operating characteristic curve (ROC curve) was used to predict the risk of all-cause death.Results:A total of 99 patients were enrolled in this study, and 94 patients completed follow-up, including 23 patients who died. Compared with PD group ( n=45), HD group ( n=54) had higher dialysis age, blood pressure, intact parathyroid hormone, alkaline phosphatase, total heart valve calcification rate, mitral valve calcification proportion, interventricular septal thickness (IVST) and left ventricular mass index (all P<0.05). The median follow-up time was 46.00(32.75, 60.25) months. Kaplan-Meier survival analysis showed that there was no significant difference in cumulative survival rate between HD group and PD group (Log-rank test χ2=0.414, P=0.520). Multivariate Cox regression analysis showed that increasing age ( HR=1.066, 95% CI 1.017-1.118, P=0.008), systolic blood pressure>140 mmHg ( HR=2.601, 95% CI 1.002-6.752, P=0.049) and increasing IVST ( HR=1.269, 95% CI 1.036-1.554, P=0.021) were independent influencing factors for all-cause death in dialysis patients after PTX. ROC curve analysis results showed that the cut-off values of age, dialysis age and IVST for predicting all-cause death after PTX were 51.5 years old ( AUC=0.673, 95% CI 0.545-0.802, P=0.013) and 75.0 months ( AUC=0.654, 95% CI 0.528-0.780, P=0.027) and 13.5 mm ( AUC=0.680, 95% CI 0.557-0.803, P=0.010) respectively. The area under the ROC curve for age, dialysis age, IVST, left ventricular hypertrophy in combination with systolic blood pressure>140 mmHg in the prediction of all-cause death after PTX was 0.776(95% CI 0.677-0.875, P<0.001). Conclusions:There is no significant difference in cumulative survival rate between HD and PD patients with SHPT after PTX. Increasing age, systolic blood pressure>140 mmHg and increasing IVST are independent risk factors for all-cause death in dialysis patients with SHPT after PTX.
