Objective To analyze the different clinical effects of colpohysterectomy combined with anterior and posterior wall colporrhaphy with or without biological mesh for uterine prolapse.Methods From January 2010 to May 2015, colpohysterectomy combined with anterior and posterior wall colporrhaphy was performed in 106 cases of uterine prolapse, including 75 cases receiving biological mesh repair (experimental group) and 31 cases of non-biological mesh (control group).Clinical and surgical information of all patients was collected, and satistial analysis was done between the two groups.Results All the operations were accomplished successfully.There were no statistical differences in bleeding amount during operation [(34.5±7.3) ml vs.(32.1±4.9) ml, t=1.973, P=0.051], time to first flatus [(29.2±4.8) d vs.(30.2±5.3) d, t=-0.907, P=0.366], postoperative hospital stay [(6.1±1.5) d vs.(6.0±1.4) d, t=0.328, P=0.744], as well as the operative time [(91.4±3.4) min vs.(95.1±10.2) min, t=-1.970, P=0.051].At one year after surgery, in the experimental group there were 74 patients cured, 1 patient improved, and no invalid or recurrence case, while in the control group there were 27 patients cured, 1 patient improved, 3 cases of recurrence and no invalid case.The treatment effect of the experimental group was significant better than that of the control group (Z=-2.571, P=0.010).Conclusions Colpohysterectomy with anterior and posterior wall colporrhaphy with biological mesh can be selected for uterine prolapse patients without contraindications.The results of surgery are better with biological mesh, with low recurrence rate.

Objective To explore the association between fibroblast growth factor 23 (FGF-23) and calcium (Ca)-phosphorus(P) metabolism and bone mineral density (BMD) in patients on peritoneal dialysis.Methods Fifty-nine patients undergoing continuous ambulatory peritoneal dialysis(CAPD) were enrolled in this study.These patients were divided into three groups as normal, osteopenic and osteoporotic, according to World Health Organization criteria based on bone mineral density T scores.Another 30 healthy people were also enrolled as control group.Levels of serum FGF-23 and 1,25 (OH)2VitD3 were measured by ELISA.Parathyroid horomone(PTH) was detected by immunoradiometric assay.Calcium and phosphorus were assessed with autobiochemistry machine.Bone density was studied by dual-energy X-ray absorptiometry (DEXA).Results The incidences of osteoporosis at the femur neck and lumbar spine in CAPD patients were 23.7％ and 35.6％, respectively.Among three groups of CADP patients, no significant differences were found in the levels of serum FGF-23, while the level of serum FGF-23 in CAPD group was higher than that in control gronp(P＜0.01).A positive correlation was found between log [FGF-23]and serum phosphorus(r=0.604, P＜0.01).However, a negative correlation was found between log[FGF-23]and 1,25(OH)2VitD3 and GFR (r=-0.401, P＜0.05; r=-0.651, P＜0.01).There were no correlations of log [FGF-23]with PTH, Ca, T scores and the duration of dialysis.Conclusions In CAPD patients, serum FGF-23 increases significantly.Serum phosphorus, renal function and 1,25(OH)2VitD3may play an important role in adjusting the level of serum FGF-23, while FGF-23 has no direct effect on bone mineralization in CAPD patients.

Objective: To investigate thoracic endovascular aortic repair (TEVAR) and “Chimney” technique for treating the involved left common carotid artery (LCCA) or left subclavian artery (LSA) in Standford B patients with aortic lesion and in-sufficient proximal anchoring area. Meanwhile, to explore the relationship between endoleaking condition and the location of lesion with the prognosis. Methods: A total of 32 relevant patients treated by TEVAR + “Chimney” technique in our hospital from 2011-09 to 2015-07 were retrospectively analyzed. Immediate post-operative image development of LCCA or LSA was observed; cerebral complications, severe upper limb ischemic symptoms and endoleaking conditions were recorded. The patients were followed-up for (3-46) months. Results: Thoracic aortic stent-graft placement was successfully carried out in all 32 patients. Immediate post-operative image development of LCCAor LSAwas favorable, no cerebral complications and no severe upper limb ischemic symptoms were observed. There were 7 patients suffered from endoleak at aortic arch including 6 with the lesion located at the greater curvature side and 1 at the small curvature side. During follow-up period, aortic stent-graft remained in a stable condition and the blood flow in “Chimney” stent was unobstructed. Endoleking condition was gradually reduced and disappeared in 5 patients, it was persisted in 2 patients. Conclusion: “Chimney” technique may prolong anchoring area and keep LCCA or LSA unobstructed, therefore expand the indication of TEVAR in a mini-invasive, safe and effective way. When aortic lesion located at the greater curvature side, the endoleaking probability could be increased.

Objective To investigate the alterations of peripheral blood T lymphocyte subsets in patients with sepsis and septic acute kidney injury, and explore the clinical significance.Methods Fifty-five patients with sepsis and forty-three patients with septic acute kidney injury were enrolled in this study. At the same period, thirty healthy subjects were enrolled as the control group.T lymphocyte subsets inclu-ding CD3 +T, CD4 +T, CD8 +T cells, and CD4 +T/CD8 +T in peripheral blood were detected by flow cy-tometry, and acute physiology and chronic health evaluation Ⅱ( APACHE Ⅱ) were graded within twenty-four hours after admission.Then, correlation of the APACHEⅡscores and T lymphocyte subsets was ana-lyzed.Results In the septic acute kidney injury group, peripheral blood CD3 +T, CD4 +T cell percenta-ges, and CD4 +T/CD8 +T ratio were significantly lower than those in the control group and the sepsis group (all P <0.05).In the septic acute kidney injury group with stage 3, CD3+T, CD4 +T cell percentages, and CD4 +T/CD8 +T ratio in the patients were significantly lower than those in stage 1 and stage 2 ( all P <0.05).In the septic acute kidney injury group,CD3 +T, CD4 +T cell percentages, and CD4 +T/CD8 +T ra-tio were significantly lower in dead group than those in survival group (all P <0.05).APACHEⅡscores in patients with sepsis were significantly negatively correlated with peripheral blood CD4 +T cell percentages and CD4 +T/CD8 +T ratio ( r =-0.645,-0.492, allP <0.05).Conclusions There are varying de-grees of cellular immune imbalance in patients with sepsis and septic acute kidney injury, characterized by decline of circulating CD3 +T, CD4 +T cell percentages, and CD4 +T/CD8 +T ratio.CD4 +T cell percenta-ges and CD4 +T/CD8 +T ratio are closely related to the severity and prognosis of septic acute kidney injury.

OBJECTIVE: To investigate the pathogens and their resistance in continuous ambulatory peritoneal dialysis (CAPD) related peritonitis. METHODS: A total of 78 cases with CAPD related peritonitis from Xiangya Hospital between January 2007 and January 2011 were reviewed. Pathogens, resistance and outcomes of the 78 cases CAPD related peritonitis were analyzed retrospectively. RESULTS: Among them, 53 cases cultured positive (66.67%), 3 of which were combined infection and 2 strains were cultured. A total of 55 strains were cultured, including 32 gram-positive strains (58.18%), 18 gram-negative strains (32.72%) and 5 fungi (9.09%). The most common pathogens were coagulase negative staphylococcus, staphylococcus aureus and Escherichia coli. Drug sensitivity test of the gram-positive strains showed that the three with lowest antibiotic resistance were linezolid (0), teicoplanin (3.13%) and vancomycin (4.0%). Drug sensitivity test of the gram-negative bacteria showed that antibiotics with the lowest resistance were amikacin and imipenem, followed by piperacillin/tazobactam and cepoperazon/sulbactam. Cephazolin had the highest resistance rate of 83.33%. Clinical outcomes: 63 cases cured (80.77%); 11 cases transferred to hemodialysis (14.1%); 4 cases died (5.13%), including 2 cases fungus infections, 1 gram-negative bacteria infection and 1 combined infection. CONCLUSION The most common pathogens causing peritoneal dialysis associated peritonitis is gram positive bacteria. In the empirical treatment, in addition to traditional treatment of Cefazolin combined with aminoglycosides, cefazolin combined with piperacillin/tazobactam or cepoperazon/sulbactam is preferable for CAPD associated peritonitis.

Objective:To investigate the status of vascular access in hemodialysis patients in our center.Methods:The general information of hemodialysis patients and types and complications of vascular access at Xiangya Hospital of Central South University from April 2015 to April 2016,were retrospectively analyzed.Results:Among 258 prevalent patients,87.60％ of them had arteriovenous fistula (AVF),while 12.40％ showed tunneled cuffed catheter.Of the 61 incident patients,80.33％ of them initiated dialysis with a non-tunneled and non-cuffed catheter,8.19％ with an AVF,9.84％ with a tunneled cuffed catheter,and 1.64％ with needle puncture.The types of AVF access included 76.55％ of wrist radiocephalic fistula,7.08％ of mid-forearm cephalic fistula,11.06％ of elbow brachiocephalic fistula,and 5.31％ of antecubital fistula and transposed basilic fistula.Seventy-seven (34.07％) patients with AVF suffered complications and wherein aneurysms accounted for 24.34％.Conclusion:In maintenance hemodialysis patients,autologous AVF is the prevalent vascular access.In the beginners for dialysis,non-tunneled and non-cuffed catheter are their choice.Additional efforts and incentives may be necessary to improve vascular access during the initiation ofhemodialysis.

Objective:To investigate the effects of continuous renal replacement therapy (CRRT) on plasma concentration, clinical efficacy and safety of colistin sulfate.Methods:Clinical data of patients received with colistin sulfate were retrospectively analyzed from our group's previous clinical registration study, which was a prospective, multicenter observation study on the efficacy and pharmacokinetic characteristics of colistin sulfate in patients with severe infection in intensive care unit (ICU). According to whether patients received blood purification treatment, they were divided into CRRT group and non-CRRT group. Baseline data (gender, age, whether complicated with diabetes, chronic nervous system disease, etc), general data (infection of pathogens and sites, steady-state trough concentration, steady-state peak concentration, clinical efficacy, 28-day all-cause mortality, etc) and adverse event (renal injury, nervous system, skin pigmentation, etc) were collected from the two groups.Results:A total of 90 patients were enrolled, including 22 patients in the CRRT group and 68 patients in the non-CRRT group. ① There was no significant difference in gender, age, basic diseases, liver function, infection of pathogens and sites, colistin sulfate dose between the two groups. Compared with the non-CRRT group, the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) and sequential organ failure assessment (SOFA) were higher in the CRRT group [APACHE Ⅱ: 21.77±8.26 vs. 18.01±6.34, P < 0.05; SOFA: 8.5 (7.8, 11.0) vs. 6.0 (4.0, 9.0), P < 0.01], serum creatinine level was higher [μmol/L: 162.0 (119.5, 210.5) vs. 72.0 (52.0, 117.0), P < 0.01]. ② Plasma concentration: there was no significant difference in steady-state trough concentration between CRRT group and non-CRRT group (mg/L: 0.58±0.30 vs. 0.64±0.25, P = 0.328), nor was there significant difference in steady-state peak concentration (mg/L: 1.02±0.37 vs. 1.18±0.45, P = 0.133). ③ Clinical efficacy: there was no significant difference in clinical response rate between CRRT group and non-CRRT group [68.2% (15/22) vs. 80.9% (55/68), P = 0.213]. ④ Safety: acute kidney injury occurred in 2 patients (2.9%) in the non-CRRT group. No obvious neurological symptoms and skin pigmentation were found in the two groups. Conclusions:CRRT had little effect on the elimination of colistin sulfate. Routine blood concentration monitoring (TDM) is warranted in patients received with CRRT.

Objective:To analyze the changes of helper T cell 22 (Th22) and related cytokines and chemokines in patients with IgA nephropathy (IgAN) and tonsillitis, and explore its relationship with clinical pathological changes.Methods:IgAN patients who were diagnosed at the Xiangya Hospital of Central South University from June 2015 to June 2016 were included. They were divided into IgAN and tonsillitis (IgAN+tonsillitis) group, IgAN group, mesangial proliferative glomerulonephritis (MsPGN) group and control group (HC) group according to renal pathology and whether associated with tonsillitis. Flow cytometry was used to detect the percentage of peripheral blood Th17, Th22 cells, CC-type chemokine receptor (CCR) 4, CCR6 and CCR10 cells. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of interleukin (IL)-22, IL-1β, IL-6, TNF-α, CCL22, CCL20 and CCL27. Immunohistochemical method (IHC) was used to detect the expression of CCL22, CCL20 and CCL27 in kidney tissue. The differences of clinicopathological indicators, the proportion of Th22 cells and related chemokine in each group were compared and analyzed.Results:A total of 44 IgAN patients were included, including 14 patients complicated with tonsillitis. Ten MsPGN patients and 16 healthy people were also included. There was no statistically significant difference in gender, age, blood pressure, kidney function, blood lipid and other biochemical indicators among the groups (all P>0.05). The peripheral blood Th22 cells and CCR10 positive cells in the IgAN group, MsPGN group, and IgAN+tonsillitis group were significantly higher than those of the control group, and serum IL-22, IL-1β, IL-6, TNF-α, CCL20, CCL22 and CCL27 levels were also significantly higher (all P<0.05). All above indexes reached the highest levels in IgAN patients combined with tonsillitis. The changes of CCL20, CCL22 and CCL27 in renal tissues were consistent with those in peripheral blood. The percentage of Th22 cells increased in hematuria-positive and higher MEST scores patients. Conclusions:Th22 cells cooperated with CCL27/CCR10 axis are involved in the pathogenesis of IgAN. Tonsillitis exacerbates clinical severity and kidney injury of IgAN.
