Clinical practice guidelines represent the best recommendations for patient care. They are developed through systematically reviewing currently available clinical evidence and weighing the relative benefits and risks of various interventions. However, clinical practice guidelines have to go through a long translation cycle from development and revision to clinical promotion and application, facing problems such as scattered distribution, high duplication rate, and low actual utilization. At present, the clinical practice guideline information platform can directly or indirectly solve the problems related to the lengthy revision cycles, decentralized dissemination and limited application of clinical practice guidelines. Therefore, this paper systematically examines different types of clinical practice guideline information platforms and investigates their corresponding challenges and emerging trends in platform design, data integration, and practical implementation, with the aim of clarifying the current status of this field and providing valuable reference for future research on clinical practice guideline information platforms.

Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.

Objective:To evaluate the immunogenicity, safety, and immune persistence of the sequential booster with the recombinant protein-based COVID-19 vaccine (CHO cell) in healthy people aged 18-84 years.Methods:An open-label, multi-center trial was conducted in October 2021. The eligible healthy individuals, aged 18-84 years who had completed primary immunization with the inactivated COVID-19 vaccine 3 to 9 months before, were recruited from Shangyu district of Shaoxing and Kaihua county of Quzhou, Zhejiang province. All participants were divided into three groups based on the differences in prime-boost intervals: Group A (3-4 months), Group B (5-6 months) and Group C (7-9 months), with 320 persons per group. All participants received the recombinant COVID-19 vaccine (CHO cell). Blood samples were collected before the vaccination and after receiving the booster at 14 days, 30 days, and 180 days for analysis of GMTs, antibody positivity rates, and seroconversion rates. All adverse events were collected within one month and serious adverse events were collected within six months. The incidences of adverse reactions were analyzed after the booster.Results:The age of 960 participants was (52.3±11.5) years old, and 47.4% were males (455). The GMTs of Groups B and C were 65.26 (54.51-78.12) and 60.97 (50.61-73.45) at 14 days after the booster, both higher than Group A′s 44.79 (36.94-54.30) ( P value<0.05). The GMTs of Groups B and C were 23.95 (20.18-28.42) and 27.98 (23.45-33.39) at 30 days after the booster, both higher than Group A′s 15.71 (13.24-18.63) ( P value <0.05). At 14 days after the booster, the antibody positivity rates in Groups A, B, and C were 91.69% (276/301), 94.38% (302/320), and 93.95% (295/314), respectively. The seroconversion rates in the three groups were 90.37% (272/301), 93.75% (300/320), and 93.31% (293/314), respectively. There was no significant difference among these rates in the three groups (all P values >0.05). At 30 days after the booster, antibody positivity rates in Groups A, B, and C were 79.60% (238/299), 87.74% (279/318), and 90.48% (285/315), respectively. The seroconversion rates in the three groups were 76.92% (230/299), 85.85% (273/318), and 88.25% (278/315), respectively. There was a significant difference among these rates in the three groups (all P values <0.001). During the sequential booster immunization, the incidence of adverse events in 960 participants was 15.31% (147/960), with rates of about 14.38% (46/320), 17.50% (56/320), and 14.06% (45/320) in Groups A, B, and C, respectively. The incidence of adverse reactions was 8.02% (77/960), with rates of about 7.50% (24/320), 6.88% (22/320), and 9.69% (31/320) in Groups A, B, and C, respectively. No serious adverse events related to the booster were reported. Conclusion:Healthy individuals aged 18-84 years, who had completed primary immunization with the inactivated COVID-19 vaccine 3 to 9 months before, have good immunogenicity and safety profiles following the sequential booster with the recombinant COVID-19 vaccine (CHO cell).

Cancer immunotherapy has rapidly become the fourth mainstream treatment alternative after surgery,radiotherapy,and chemotherapy,with some promising results.It aims to kill tumor cells by mobilizing or stimulating cytotoxic immune cells.However,the clinical applications of tumor immunotherapies are limited owing to a lack of adequate delivery pathways and high toxicity.Recently,nanomaterials and genetic engineering have shown great potential in overcoming these limitations by protecting the delivery of antigens,activating targeted T cells,modulating the immunosuppressive tumor microenvironment,and improving the treatment efficacy.Bacillus Calmette-Guérin(BCG)is a live attenuated Mycobacterium bovis vaccine used to prevent tuberculosis,which was first reported to have antitumor activity in 1927.BCG therapy can activate the immune system by inducing various cytokines and chemokines,and its specific immune and inflammatory responses exert antitumor effects.BCG was first used during the 1970s as an intravesical treatment agent for bladder cancer,which effectively improved immune antitumor activity and prevented tumor recurrence.More recently,nano-BCG and genetically engineered BCG have been proposed as treatment alternatives for bladder cancer due to their ability to induce stronger and more stable immune responses.In this study,we outline the development of nano-BCG and genetically engineered BCG for bladder cancer immunotherapy and review their potential and associated challenges.

Objective:To investigate the correlation between complement C3 and urine protein level and proteinuria remission status in patients with primary membranous nephropathy (PMN), and better guide individualized clinical treatment.Methods:It was a single-center retrospective study. The clinical data of PMN patients who underwent renal biopsy in the First Affiliated Hospital of Nanjing Medical University from January 2017 to June 2022 were collected. Patients with 24 h urinary protein ≥ 3.5 g were followed up after receiving standard treatment, and the last outpatient or inpatient review was used as the end point of follow-up. 24 h urine protein was collected to evaluate the remission status of proteinuria. Kaplan-Meier method was used to analyze the correlation between serum and renal complements and proteinuria remission. Cox regression analysis method was used to analyze the correlation between serum C3 level and renal tissue C3 deposition and proteinuria remission.Results:This study included 507 PMN patients with 312 (61.54%) males, aged 54 (43, 64) years old. Compared with 24 h urinary protein < 3.5 g group, proportion of males ( χ2=22.479, P<0.001), age ( Z=-2.521, P=0.012), systolic blood pressure ( Z=-4.148, P<0.001), diastolic blood pressure ( Z=-4.084, P<0.001), serum anti-phospholipase A2 receptor (PLA2R) antibody titer ( Z=-7.019, P<0.001), total cholesterol ( Z=-8.796, P<0.001), triglyceride ( Z=-6.158, P<0.001), low density lipoprotein cholesterol ( Z=-8.716, P<0.001), serum creatinine ( Z=-7.368, P<0.001), serum C3 ( Z=-3.663, P<0.001), serum C4 ( Z=-6.560, P<0.001), proportion of glucocorticoid use ( χ2=116.417, P<0.001) and proportion of immunosuppressant use ( χ2=53.839, P<0.001) were all higher, while serum albumin ( Z=12.518, P<0.001), estimated glomerular filtration rate ( Z=6.345, P<0.001) and serum IgG ( Z=7.321, P<0.001) were all lower in 24 h urinary protein ≥3.5 g group. There were 268 patients included in the follow-up cohort with baseline 24 h urinary protein of 7.15 (5.14, 10.24) g, serum anti-PLA2R antibody titer of 61.44 (14.35, 193.24) RU/ml, serum C3 of 1.005 (0.864, 1.150) g/L, and serum C4 of 0.260 (0.214, 0.317) g/L. Kaplan-Meier survival curve showed that the incomplete remission rate of proteinuria in serum C3 > 1.005 g/L group was lower than that in serum C3 ≤ 1.005 g/L group (log-rank χ2=4.757, P=0.029). There was no significant difference in the incomplete remission rate of proteinuria between serum C4 ≤ 0.260 g/L group and serum C4 > 0.260 g/L group (log-rank χ2=3.543, P=0.060). Renal C1q (log-rank χ2=0.167, P=0.683) and C4 (log-rank χ2=1.927, P=0.165) deposition had no significant effects on proteinuria remission in PMN patients. The incomplete remission rate of proteinuria in patients with renal C3 deposition was higher than that in patients without renal C3 deposition (log-rank χ2=7.018, P=0.008). Univariate Cox regression analysis showed that serum C3 level and C3 deposition in renal tissues were influencing factors of incomplete remission of proteinuria (both P<0.05), while adjusting for gender, age, mean arterial pressure, serum anti-PLA2R antibody, serum albumin and 24 h urinary protein, serum C3 ≤ 1.005 g/L ( HR=1.374, 95% CI 1.021-1.849, P=0.036), C3 deposition in renal tissues ( HR=1.949, 95% CI 1.098-3.460, P=0.023), and serum C3 ≤ 1.005 g/L combined with C3 deposition in renal tissues ( HR=1.472, 95% CI 1.093-1.983, P=0.011) were independent influencing factors of incomplete remission of proteinuria. Conclusions:The serum C3 level and C3 deposition in renal tissues are closely related to urinary protein level and proteinuria remission status in PMN patients. The patients with higher urinary protein have higher serum C3. For patients with massive proteinuria, serum C3 ≤ 1.005 g/L, C3 deposition in renal tissues, serum C3 ≤ 1.005 g/L combined with C3 deposition in renal tissues are independent risk factors of incomplete remission of proteinuria.

Objective:To investigate the epidemiology of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in patients with maintenance hemodialysis (MHD) in Jiangsu province during SARS-CoV-2 pandemic in China from December 7, 2022 to January 27, 2023, and to analyze the influencing factors of all-cause death.Methods:It was a multi-center cross-sectional investigation. Structured questionnaire was used to collect patient information by medical staff of each hemodialysis center (room) as investigators. Part of the demography data and laboratory examination data came from the Jiangsu Province Hemodialysis Data Information System. MHD patients from hemodialysis centers (rooms) at all levels of medical institutions and independent hemodialysis institutions in Jiangsu province during the outbreak of SARS-CoV-2 infection were included, and the clinical characteristics and all-cause mortality of confirmed and suspected cases of SARS-CoV-2 infection were analyzed.Results:Questionnaire surveys and data analysis on 57 278 patients in 407 hemodialysis centers (rooms) were completed, accounting for 90.41% of the total number of MHD patients (63 357 cases) in Jiangsu province during the same period. There were 24 038 cases (41.97%) of SARS-CoV-2 infection and 14 805 cases (25.85%) of suspected infection, which were widely distributed in all dialysis centers in Jiangsu province. After clinical classification of 38 843 confirmed and suspected SARS-CoV-2 infection cases, 3 662 cases were severe and critical cases, accounting for 9.43% of the infected and suspected cases. Among the patients who had completed the questionnaires, there were 1 812 all-cause deaths, with an all-cause mortality rate of 3.16%. Multivariate logistic regression analysis showed that elderly (taking ≤50 years as a reference, 51-59 years: OR=1.583, 95% CI 1.279-1.933, P=0.001; 60-69 years: OR=3.972, 95% CI 3.271-4.858, P<0.001; 70-79 years: OR=7.236, 95% CI 5.917-8.698, P<0.001; ≥80 years: OR=11.738, 95% CI 9.459-14.663, P<0.001), male ( OR=1.371, 95% CI 1.229-1.529, P<0.001), and co-infection with hepatitis B virus (HBV) (positive serum HBV surface antigen, OR=0.629, 95% CI 0.484-0.817, P<0.001) were independent influencing factors for all cause mortality. Receiver-operating characteristic curve analysis showed that the area under the curve for male, age and current HBV infection prediction of all-cause death was 0.529 ( P<0.001), 0.724 ( P<0.001) and 0.514 ( P=0.042), respectively, and the cut-off value for age prediction of all-cause death was 65.5 years old. Compared with patients without HBV infection, MHD patients with HBV infection significantly reduced the proportion of severe and critically ill patients, all-cause hospitalizations and all cause deaths when infected with SARS-CoV-2 (4.99% vs. 6.41%, χ2=6.136, P=0.013; 8.90% vs. 11.44%, χ2=11.662, P<0.001; 2.01% vs. 3.37%, χ2=10.713, P=0.001, respectively). Conclusion:The MHD patients in Jiangsu province are susceptible to SARS-CoV-2. Elderly age and male gender are independent risk factors for death in MHD patients during the epidemic, while the HBV infection may be a protective factor for death of MHD patients infected with SARS-CoV-2.

Objective:To investigate the curative efficacy of radical prostatectomy (RP) for T 4 stage prostate cancer invading bladder neck. Methods:The clinical data of 22 patients with T 4 stage prostate cancer invading bladder neck treated with RP from April 2013 to March 2021 were analyzed retrospectively. The mean age of the patients was (64.09±6.33) years, and the preoperative blood PSA was 57.70(39.40, 68.56) ng/ml. Preoperative MRI or PSMA-PET examination revealed bladder neck invasion, including 16 cases (72.73%) of urinary retention. Clinical stage of T 4N 0M 0 accounted for 40.91% (9/22), T 4N 1M 0 accounted for 45.45% (10/22), and T 4N 1M 1 accounted for 13.64% (3/22). Preoperative patients were not treated with neoadjuvant endocrine or chemotherapy. Laparoscopic or robotic assisted laparoscopic radical prostatectomy and pelvic lymph node dissection were performed. Results:The 22 operations were successfully completed without conversion. The operation time was(184.27±34.82) min, the amount of intraoperative bleeding was (210.91±83.03) ml, the retention time of drainage tube was (4.73 ± 1.03) days, the recovery of gastrointestinal function took 3 (2, 3) days, and the postoperative hospital stay was (6.68 ± 1.39) days. Postoperative pathology showed that the Gleason score of 7 points accounted for 4.54% (1/22), 8 points accounted for 13.64% (3/22), and 9 points accounted for 81.82% (18/22). The positive rate of margin was 81.82% (18/22). Pathological stage of T 4N 0M 0 accounted for 22.73% (5/22), T 4N 1M 0 accounted for 63.64% (14/22), and T 4N 1M 1 accounted for 13.64% (3/22), of which extracapsular or seminal vesicle invasion accounted for 90.91% (20/22). The incidence of postoperative complications above grade 3 was 9.09% (2/22), and the rate of urinary control recovery after 3 months of surgery was 90.91% (20/22). 16 patients with preoperative urinary retention were able to urinate normally after operation. All patients were treated with adjuvant androgen deprivation therapy (ADT) with or without antiandrogens, and 13 cases (59.09%) were treated with adjuvant radiotherapy. The postoperative PSA value before adjuvant treatment was 2.53 (0.51, 5.44) ng/ml. The median survival time was not reached. Two patients died of prostate cancer at 71 and 84 months and one patient died of heart disease at 28 months. Conclusions:RP surgery could effectively relieve the condition of urinary retention with low incidence of operative complications. Although the positive rate of surgical margin is high, RP could be used as one of the treatment options for T 4 stage prostate cancer invading bladder neck, while the long-term effect is still needed to be further analyzed.

Objective:To investigate the predictive value of abnormal heart rate circadian rhythm for all-cause mortality in stage 5 chronic kidney disease (CKD 5) patients.Methods:The retrospective study was performed in CKD 5 patients enrolled from the First Affiliated Hospital of Nanjing Medical University (Jiangsu Province Hospital) and the Affiliated BenQ Hospital of Nanjing Medical University from February, 2011 to December, 2019. A total of 159 healthy volunteers were enrolled as the healthy control group during the same period. The circadian rhythm of heart rate was monitored by 24-hour Holter. Related indices (including 24-hour, daytime and nighttime mean heart rate, night/day heart rate ratio, 24-hour maximum heart rate, 24-hour minimum heart rate and difference between maximum and minimum of 24-hour heart rate) were calculated. Non-dipping heart rate was defined as night/day heart rate ratio greater than 0.9. Cox regression model was used to analyze the risk factors of all-cause mortality in CKD 5 patients. Kaplan-Meier survival curve and Log-rank test were used to compare the differences of cumulative mortality between high ratio group (night/day heart rate ratio>0.91) and low ratio group (night/day heart rate ratio≤0.91). The nonlinear relationship between night/day heart rate ratio and all-cause mortality was analyzed by restricted cubic spline plot. Time-dependent receiver operating characteristic (ROC) curve was used to analyze the predictive value of night/day heart rate ratio for all-cause mortality in CKD 5 patients.Results:A total of 159 healthy volunteers and 221 CKD 5 patients were included in this study. There were 123 males (55.66%) and the age was (52.72±13.13) years old in CKD 5 patients. The total median follow-up time was 50.0 months. Compared with controls, 24-hour, nighttime mean heart rate, 24-hour minimum heart rate in CKD 5 patients were increased (all P<0.05), furthermore, the night/day heart rate ratio was higher [(0.91±0.09) vs (0.81±0.08), P<0.001], showing "non-dipping heart rate". However, the 24-hour maximum heart rate and the difference between maximum and minimum of 24-hour heart rate in CKD 5 patients were lower than controls (both P<0.05). Multivariate Cox regression analysis showed that the increased night/day heart rate ratio (per 0.1 increase, HR=1.557, 95% CI 1.073-2.258, P=0.020) was an independent influencing factor for all-cause mortality in CKD 5 patients. Kaplan-Meier survival curve analysis showed that the cumulative mortality of the high ratio group was significantly increased than that of the low ratio group (Log-rank test χ 2=7.232, P=0.007). From the restricted cubic spline plot, there was a linear effect between night/day heart rate ratio and all-cause mortality ( P=0.141), and when night/day heart rate ratio was above 0.91, the risk of all-cause mortality was significantly increased in CKD 5 patients. According to time-dependent ROC curve, the accuracy of night/day heart rate ratio in predicting all-cause mortality was 70.90% even when the survival time was up to 70.0 months. Conclusions:The circadian rhythm of heart rate in CKD 5 patients displays "non-dipping" state. High night/day heart rate ratio is an independent influencing factor for all-cause mortality in CKD 5 patients.

Objective:To determine the prognostic values of clinical and laboratory features at the time of presentation on renal survival of patients with myeloperoxidase (MPO)-antineutrophil cytoplasmic antibody(ANCA)-associated glomerulonephritis (MPO-ANCA-GN).Methods:A total of 172 patients with MPO-ANCA-GN and hospitalized at the First Affiliated Hospital of Nanjing Medical University from January 2005 to December 2018 were enrolled. The baseline clinical characteristics and renal biopsy pathological data were analyzed, and the renal prognosis was followed up. The clinical and pathological characteristics of different renal prognosis in all patients and 112 patients who underwent renal biopsy were analyzed, and the related factors affecting renal survival were further discussed.Results:Among these 172 patients, 81 were males and 91 were females. The median serum creatinine at diagnosis was 343.7(174.2, 606.6) μmol/L and the median estimated glomerular filtration rate (eGFR) was 15.81(7.61, 38.04) ml·min -1·(1.73 m 2) -1. In total, 76 patients (44.2%) received initial renal replacement therapy (RRT). During a median follow-up duration of 20(3, 60) months, 73 patients (42.4%) progressed to end-stage renal disease (ESRD) and required dialysis, including 6 (8.2%) patients who entered RRT during follow-up and 67 (91.8%) patients who received RRT at the beginning. Among the 112 patients who underwent renal biopsy, the proportion of patients who progressed to ESRD in the sclerotic group was the highest (15/25, 60.0%). The baseline serum creatinine level ( P<0.001), urine red blood cell count ( P=0.012) and the proportion of glomerular sclerosis ( P=0.002) in the non-dialysis dependent group were significantly lower than those in the dialysis dependent group, while the levels of eGFR ( P<0.001), serum albumin ( P=0.002) and hemoglobin ( P<0.001) were higher than those of the dialysis-dependent group. Kaplan-Meier survival analysis showed that the renal survival rate of the focal group was the highest ( χ2=19.488, P<0.001, log-rank test), while the renal survival rate of the sclerotic group was significantly lower than that of the crescentic group ( χ2=5.655, P=0.017); higher levels of serum creatinine (>320 μmol/L, χ2=77.229, P<0.001) and urine red blood cell count (>300 cells/μl, χ2=8.511, P=0.004), lower levels of rheumatoid factor (<20 IU/ml, χ2=8.610, P=0.003), serum albumin (<30 g/L, χ2=11.060, P=0.001) and hemoglobin (<90 g/L, χ2=21.921, P<0.001) were associated with lower renal survival rate; in terms of treatment, the renal survival rate of the glucocorticoids plus mycophenolate mofetil group was significantly higher than that of the glucocorticoids plus cyclophosphamide ( χ2=5.056, P=0.025) or the glucocorticoids alone group ( χ2=16.459, P<0.001). Multivariate Cox regression showed that baseline serum creatinine >320 μmol/L ( HR=8.803, 95% CI 3.087-25.106, P<0.001) and serum albumin <30 g/L ( HR=2.566, 95% CI 1.246-5.281, P=0.011) were the related factors affecting renal survival. Conclusion:Serum creatinine and albumin levels of MPO-ANCA-GN patients at diagnosis may be the related factors that affect the patient's renal prognosis.

Objective To study shortdated postoperative variation characteristics of bone turnover markers (BTMs) in uremic patients with secondary hyperparathyroidism (SHPT) underwent parathyroidectomy (PTX). Methods A total of 19 uremic patients with SHPT underwent successful PTX, hospitalized in the Department of Nephrology, The First Affiliated Hospital of Nanjing Medical University from January 2017 to April 2017, were enrolled in the study. The operative model for all enrolled patients was total parathyroidectomy with forearm autotransplantation. The baseline epidemiological and clinical data before PTX and the levels of serum intact parathyroid hormone (iPTH) and serum BTMs after PTX (in the 1st, 3rd and 7th postoperative day) were collected. The correlations between serum iPTH and serum BTMs before PTX and the trend analysis of serum BTMs after PTX were studied. Results The levels of serum iPTH, serum alkaline phosphatase (ALP), serum typeⅠcollagen cross-linked C-telopeptides (CTX) and serum tartrate-resistant acid phosphatase 5b (TRACP-5b) before PTX were increased, in turn, (1512.4±612.0) ng/L, 267.4(153.1, 424.2) U/L, (5.78±1.15)μg/L and (8.79 ± 4.61) IU/L. Positive correlations between ALP and iPTH (r=0.577, P=0.010), TRACP-5b and iPTH (r=0.640, P=0.003), and ALP and TRACP-5b (r=0.698, P=0.001) were found. The serum levels of ALP increased, while the serum levels of CTX and TRACP-5b decreased within 7 days after PTX. Conclusions Renal osteodystrophy (ROD) with high bone turnover rate is common in uremic patients with severe SHPT. The activities of osteoblast and osteoclast are up-regulated in coupling with positive correlations to serum levels of iPTH. Increased activities of osteoblast and decreased activities of osteoclast were found shortdated postoperatively.
