Objective:To analyze the clinicopathological characteristics, treatment responses and kidney outcomes of patients with atypical membranous nephropathy (MN), and to provide information for the clinical practice.Methods:The clinical data of patients with atypical MN and synchronous primary MN who were diagnosed, treated and followed up in Peking University First Hospital from January 2008 to June 2020 were retrospectively collected and analyzed. Clinicopathological features, treatment responses and kidney prognosis were compared between the two groups. The expression of phospholipase A2 receptor (PLA2R) in kidney tissues was detected by immunofluorescence. Serum anti-PLA2R antibody was detected by enzyme-linked immunosorbent assay. Clinicopathological indexes were compared between PLA2R-related MN group and non-PLA2R-related MN group. Kaplan-Meier (Log-rank test) survival curve and multivariate Cox regression analysis methods were used to analyze the influencing factors of kidney prognosis in patients with atypical MN. The primary endpoint of renal adverse outcome was renal insufficiency, defined as end-stage renal disease or estimated glomerular filtration rate (eGFR) decline>30% baseline and<60 ml·min -1·(1.73 m 2) -1. Results:A total of 65 atypical MN patients were enrolled in this study. Compared with primary MN ( n=324), patients with atypical MN had younger age ( Z=-4.229, P<0.001), higher proportion of hematuria ( χ2=5.555, P=0.018), higher level of urinary protein ( Z=2.228, P=0.026) and lower level of eGFR ( t=-5.108, P<0.001); the proportion of IgG4 deposition in kidneys was lower ( χ2=8.081, P=0.004), and the proportions of IgA ( χ2=16.969, P<0.001) and IgM ( χ2=9.281, P=0.002) deposition were higher. There was no significant difference on gender, serum albumin, positive proportion of anti-PLA2R antibody, anti-PLA2R antibody level and kidney C3/C1q deposition between the two groups (all P>0.05). The proportions of atypical MN patients receiving renin-angiotensin aldosterone system inhibitors (49.3% vs 57.1%), calcineurin inhibitors (27.7% vs 19.1%) and cyclophosphamide (21.5% vs 23.8%) were comparable to those of primary MN patients (all P>0.05). The rates of clinical remission (80.0% vs 77.2%), partial remission (44.6% vs 44.1%), complete remission (35.4% vs 33.1%), spontaneous remission (36.9% vs 42.6%), response to cyclophosphamide (85.7% vs 81.8%), response to calcineurin inhibitor (88.9% vs 79.0%), and relapse (30.8% vs 26.8%) in atypical MN patients were comparable to those in primary MN patients (all P>0.05). During the follow-up 30.0(21.5, 61.5) months, 15 atypical MN patients (23.1%) had eGFR reduction>30%, among whom 7 patients (10.8%) had eGFR reduction>50% and 3 patients (4.6%) had end-stage kidney disease. There was no significant difference on poor kidney prognosis between the two groups (all P>0.05). Kaplan-Meier survival curve showed that patients with age>39 years old ( χ2=10.092, P=0.001), eGFR≤100 ml·min -1·(1.73 m 2) -1( χ2=5.491, P=0.019), tubular interstitial lesion ( χ2=6.999, P=0.008) and no nephropathy remission ( χ2=22.952, P<0.001) had earlier poor renal prognosis. Multivariate Cox regression analysis showed that no nephropathy remission ( HR=12.604, 95% CI 2.691-59.037, P=0.001) was an independent influencing factor for poor renal prognosis in atypical MN patients. Conclusion:No significant difference is found between atypical MN and primary MN on treatment responses and kidney prognosis, which implies that clinical practice of atypical MN can be performed by referring to the guidelines and experience of primary MN.

Cases with surgical methods as complete open surgery or laparoscopy combined with open surgery, the operation time, time to postoperative initial liquid food intake, cases with or without postoperative complications, cases with postoperative duration of hospital stay as ≤10 days or >10 days were 58, 1, (281±57)minutes, (5±1)days, 33, 26, 14, 45 in patients admitted in 2000?2010, respec-tively. The above indicators in patients admitted in 2011?2021 were 140, 147, (261±82)minutes, (3±1)days, 233, 54, 198, 89, respectively. There were significant differences in the above indicators between patients admitted in 2000?2010 and 2011?2021 ( χ2=49.04, t=2.24, 7.53, χ2=17.56, 26.02, P<0.05). There was no death in the 346 patients. (3) Analysis of prognosis of patients with synchro-nous colorectal liver metastasis in 2000?2010 and 2011?2021. Of the 346 patients, 295 cases were followed up for 47(range, 1?108)months. Of the 29 patients admitted in 2000?2010 who were followed up, there were 27 cases died. The median survival time, 1-, 3-, 5-year overall survival rates, 1-, 3-, 5-year disease free survival rates of patients admitted in 2000?2010 were 18.0 months (95% confidence interval as 12.7?23.3 months), 82.8%, 11.5%, 3.8%, 53.6%, 8.3%, 4.2%, respec-tively. Of the 266 patients admitted in 2011?2021 who were followed up, there were 109 cases died. The median survival time, 1-, 3-, 5-year overall survival rates, 1-, 3-, 5-year disease free survival rates of patients admitted in 2011?2021 were 54.0 months (95% confidence interval as 38.1?70.4 months), 93.3%, 61.8%, 47.0%, 68.2%, 33.7%, 28.3%, respectively. There were significant differences in overall survival rate and disease free survival rate between patients admitted in 2000?2010 and 2011?2021 ( χ2=47.57, 9.17, P<0.05). Conclusions:With the increase of the operation volume of simultaneous resection of synchronous colorectal liver metastasis, the operation time, time to postoperative initial liquid food intake, postoperative duration of hospital stay and postoperative complications have significantly decreased, while the overall survival rate and disease free survival rate have significantly increased.

Objective:To investigate clinical efficacy of conformal sphincter preservation operation (CSPO) versus intersphincteric resection (ISR) in the treatment of low rectal cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 183 patients with low rectal cancer who were admitted to two medical centers (117 in the Changhai Hospital of Naval Medical University and 66 in the Huashan Hospital of Fudan University) from August 2011 to April 2020 were collected. There were 110 males and 73 females, aged (57±11)years. Of 183 patients, 117 cases undergoing CSPO were allocated into CSPO group, and 66 cases undergoing ISR were allocated into ISR group, respectively. Observation indicators: (1) surgical situations of patients with low rectal cancer in the two groups; (2) postoperative complications of patients with low rectal cancer in the two groups; (3) follow-up; (4) influencing factors for prognosis of patients with low rectal cancer; (5) influencing factors for satisfaction with the anal function of patients with low rectal cancer. Follow-up was conducted using outpatient examination, questionnaire and telephone interview to determine local recurrence, distal metastasis, survival, stomal closure, satisfaction with the anal function of patients. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M (range). Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. Comparison of ordinal data was analyzed using the rank sum test.The Kaplan-Meier method was used to draw survival curves, and life table method was used to calculate survival rates. Log-rank test was used for survival analysis. Univariate analysis was performed using the linear regression. Variables with P<0.10 in the univariate linear regression analysis were included for multivariate analysis. Multivariate analysis was performed using the COX stepwise regression model and linear regression analysis. Results:(1) Surgical situations of patients with low rectal cancer in the two groups: cases with laparoscopic surgery, operation time, volume of intraoperative blood loss, distance from tumor to distal margin, cases with postoperative chemotherapy, duration of postoperative hospital stay were 44, (165±54)minutes, (142±101)mL, (0.6±0.4)cm, 76, (6.6±2.5)days for the CSPO group, respectively, versus 55, (268±101)minutes, (91±85)mL, (1.9±0.6)cm, 9, (7.9±4.7)days for the ISR group, showing significant differences between the two groups ( χ2=35.531, t=8.995, -3.437, -3.088, χ2=44.681, t=2.267, P<0.05). (2) Postoperative complications of patients with low rectal cancer in the two groups: 19 patients in the CSPO group had complications. There were 6 cases with grade Ⅰ complications, 12 cases with grade Ⅱ complications, 1 case with grade Ⅲb complication. Fourteen patients in the ISR group had complications. There were 4 cases with grade Ⅰ complications, 7 cases with grade Ⅱ complications, 1 case with grade Ⅲa complication, 2 cases with grade Ⅲb complications. There was no significant difference in the postoperative complications between the two groups ( χ2=0.706, P>0.05). Patients with complications in the two groups were improved after symptomatic and supportive treatment. There was no perioperative death in the postoperative 30 days of the two groups. (3) Follow-up: 183 patients received follow-up. Patients of the CSPO group and ISR group were followed up for (41±27)months and (37±19)months, respectively, showing no significant difference between the two groups ( t=-1.104, P>0.05). There were 2 cases with local recurrence and 9 cases with distal metastasis of the CSPO group, respectively, versus 3 cases and 4 cases of the ISR group, showing no significant difference between the two groups ( χ2=1.277, 0.170, P>0.05). The 3-year disease-free survival rate and 3-year total survival rate were 84.0% and 99.0% for the CSPO group, versus 88.6% and 92.8% for the ISR group, showing no significant difference between the two groups ( χ2=0.218, 0.002, P>0.05). The stomal closure rate was 92.16%(94/102) and 96.97%(64/66) for 102 patients of CSPO group and 66 patients of ISR group up to postoperative 12 months,respectively, showing no significant difference between the two groups ( χ2=1.658, P>0.05). Of the 8 cases without stomal closure in the CSPO group, 2 cases refused due to advanced age, 4 cases subjectively refused, and 2 cases were irreducible due to scar caused by radiotherapy. Two cases in the ISR group had no stomal closure including 1 case of postoperative liver metastasis and 1 case of subjective refusal. There were 92 and 61 patients followed up to 12 months after stomal closure, of which 75 cases and 38 cases completed questionnaires of satisfaction with the anal function. The satisfaction score with the anal function was 6.8±2.8 and 5.4±3.0 for CSPO group and ISR group, respectively, showing a significant difference between the two groups ( t=-2.542, P<0.05). Fifty-four cases in the CSPO group and 21 cases in the ISR group had satisfaction score with the anal function >5, showing no significant difference between the two groups ( χ2=3.165, P>0.05). (4) Influencing factors for prognosis of patients with low rectal cancer: results of COX stepwise regression analysis showed that gender and pT staging were independent influencing factors for disease-free survival rate of patients with low rectal cancer ( hazard ratio=2.883, 1.963, 95% confidence interval as 1.090 to 7.622, 1.129 to 3.413, P<0.05). Gender and pT staging were independent influencing factors for total survival rate of patients with low rectal cancer ( hazard ratio=10.963,3.187, 95% confidence interval as 1.292 to 93.063, 1.240 to 8.188, P<0.05). (5) Influencing factors for satisfaction with the anal function of patients with low rectal cancer: results of univariate analysis showed that surgical method and tumor differentiation degree were related factors for satisfaction with the anal function of patients with low rectal cancer (partial regression coefficient=1.464, -1.580, 95% confidence interval as 0.323 to 2.605, -2.950 to -0.209, P<0.05). Results of multivariate analysis showed that surgical method, tumor differentiation degree and preoperative radiotherapy were independent influencing factors for satisfaction with the anal function of patients with low rectal cancer (partial regression coefficient=1.637, -1.456, -1.668, 95% confidence interval as 0.485 to 2.788, -2.796 to -0.116, -2.888 to -0.447, P<0.05). Conclusion:Compared with ISR, CSPO can safely preserve the anus in the treatment of low rectal cancer, without increasing the incidence of postoperative complications, which can also guarantee the oncological safety and improve the postoperative anal function.

Objective:This study aims to analyze the prognosis of patients who underwent a simultaneous operations for colorectal cancer and liver metastases, and to establish a prognostic scoring system for these patients.Methods:From January 2010 to March 2019, the clinicopathological data of patients with colorectal cancer and liver metastases simultaneously operated at Shanghai Changhai Hospital were collected. The clinicopathological prognostic factors on tumor recurrence and survival outcomes on follow-up were analyzed. Single and multiple factors Cox regression analyses were used to determine the risk factors which affected the prognosis of patients. Using the risk factors of poor prognosis on Cox analysis, 1 point was given to each risk factor. Patients were then divided into different groups according to the different total scores. The median overall survival and disease-free survival of each group were analyzed.Results:Of 234 patients included in this study, there were 126 males and 108 females. The average age was (57.4±10.8) years. The median survival was 44.85 months. The 1-, 3-, and 5-year survival rates of the whole group were 87.3%, 55.2%, and 22.9%, respectively. Primary tumor in right colon, preoperative carcinoembryonic antigen ≥200 ng/ml, multiple liver metastases, and poorly differentiated adenocarcinoma/mucinous adenocarcinoma were independent risk factors of poor prognosis. After 1 point was given to each of the above 4 items, patients were then divided into the low-risk (0-1) and high-risk (2-4) groups. The median survivals of patients in the low-risk group ( n=174) and high-risk group ( n=60) were 53 months and 29 months, respectively. The corresponding median disease-free survivals were 21.34 months and 8.48 months, respectively. The differences between the 2 groups were significant ( P<0.05). Conclusion:The results of this study preliminary established a predictive scoring system for patients with simultaneous colorectal cancer and liver which can play a role in selecting treatment options for these patients.

Objective:To evaluate the effect of imatinib on growth impairment in children with chronic myeloid leukemia (CML-CP) in the chronic phase.Methods:From July 2018 to July 2019, questionnaires were distributed to CML children aged <18 years at the time of diagnosis who were receiving imatinib for at least 3 months or to their parents in China. The height-for-age standard deviation score (HtSDS) and the difference of standard deviation integral (△HtSDS) were used to explore the change in height with imatinib therapy.Results:The data of 238 respondents were included; 138 (58.0% ) respondents were men. The median age at the first diagnosis of CML was 11.0 years (range, 1.4-17.9 years) , and 93 (39.0% ) respondents were at the prepuberty stage. At the time of completing the questionnaires, the median age was 15.0 years (range, 2.0-34.0 years) . The median duration of imatinib therapy was 28 months (range, 3-213 months) . Among all the respondents, the mean HtSDS when completing the questionnaires (-0.063±1.361) was significantly lower than that at the time of starting imatinib treatment (0.391±1.244) ( P<0.001) . Total 71.0% respondents showed growth impairment that was more common in those starting imatinib therapy at prepubertal age than in those starting at pubertal age. Multivariate analysis showed that younger at the start of imatinib therapy ( P<0.001) and longer duration of imatinib therapy ( P<0.001) were significantly associated with severe growth impairment on imatinib therapy. Conclusions:Imatinib induced growth impairment in children with CML-CP. Younger the age of initiation and longer the duration of imatinib therapy, more obvious the effect of imatinib on growth impairment.

OBJECTIVE: To investigate the surgical efficacy and prognostic factors of T3NxM0 middle-low rectal cancer without neoadjuvant therapy. METHODS: Clinical data of patients with middle-low rectal cancer undergoing TME surgery with T3NxM0 confirmed by postoperative pathology at Colorectal Surgery Department of Changhai Hospital from January 2008 to December 2010 were analyzed retrospectively. INCLUSION CRITERIA: (1)no preoperative neoadjuvant chemoradiotherapy (nCRT); (2) complete preoperative evaluation, including medical history, preoperative colonoscopy or digital examination, blood tumor marker examination, and imaging examination; (3) distance between tumor lower margin and anal verge was ≤ 10 cm; (4) negative circumferential resection margin (CRM-). Finally, a total of 331 patients were included in this study. According to the number of metastatic lymph node confirmed by postoperative pathology, the patients were divided into N0 group without regional lymph node metastasis (190 cases) and N+ group with regional lymph node metastasis (141 cases). The perioperative conditions, local recurrence, distant metastasis and prognostic factors were analyzed. RESULTS: Compared to N0 group in the perioperative data, N+ group had higher ratio of tumor deposit [29.8%(42/141) vs. 0, χ²=64.821, P<0.001] and vascular invasion [7.1%(10/141) vs. 0.5%(1/190),χ²=10.860, P<0.001]. There were no significant differences in tumor diameter, number of lymph nodes detected, positive nerve invasion, degree of tumor differentiation, morbidity of postoperative complication and postoperative adjuvant chemotherapy rate between the two groups (all P>0.05). The median follow-up period was 73.4 months. The merged 5-year local recurrence rate was 2.7%(9/331), 5-year distant metastasis rate was 23.3% (77/331), 5-year disease-free survival (DFS) rate was 73.4%, and 5-year overall survival (OS) rate was 77.2%. Multivariate analysis showed that lymph node metastasis (HR=3.120, 95%CI: 1.918 to 5.075, P<0.001), nerve invasion (HR=0.345, 95%CI: 0.156 to 0.760, P=0.008) and vascular invasion (HR=0.428, 95%CI: 0.189 to 0.972, P=0.043) were independent risk factors for DFS in patients with T3NxM0 rectal cancer after operation. Preoperative carcinoembryonic antigen level (HR=1.858, 95%CI:1.121 to 3.079, P=0.016), lymph node metastasis (HR=3.320, 95%CI: 1.985 to 5.553, P<0.001) and nerve invasion (HR=0.339, 95%CI: 0.156 to 0.738, P=0.006) were independent risk factors for OS in patients with T3NxM0 rectal cancer after operation. CONCLUSIONS Optimal local control rate of middle-low rectal cancer patients with T3NxM0 and CRM- can be achieved by standard TME surgery alone. For patients with preoperative elevated blood carcinoembryonic antigen level, regional lymph node metastasis, or neurovascular invasion confirmed by pathology after surgery, adjuvant chemoradiotherapy should be actively applied after surgery to improve prognosis.

Objective: To evaluate the quality of clinical practice guidelines for kidney diseases in China and provide reference for selecting suitable high-quality guidelines for primary care and developing standardized guidelines. Methods: The China Guideline Clearinghouse, China Biology Medicine disc, VIP Database, Wanfang Database and CNKI, and other resources were searched from January 2013 to July 2018. In accordance with the criteria for inclusion and exclusion, the published guidelines for kidney diseases were screened. The Appraisal of Guidelines Research and Evaluation-China (AGREE-China) was used to systematically assess the current status of domestic guidelines for kidney diseases. Results: A total of 18 guidelines for kidney diseases were included, covering different types of kidney disease such as glomerulonephritis, nephrotic syndrome, end-stage renal disease and other diseases. The overall score ranged from 30 to 68, with an average score of 47.3. The average scores of these guidelines were 20.1, 12.8, 0.5, 9.9 and 3.9 in five review fields including scientificity/rigorism, effectiveness/safety, economy, availability/feasibility, and conflicts of interest, respectively. Of these 18 guidelines, 8(44.4%) guidelines were strongly recommended, and 10(55.6%) guidelines were weakly recommended. Conclusions There are still deficiencies in scientificity/rigorism and economy in current guidelines for kidney diseases in China. The AGREE-China can be used as an evaluation tool for guidelines for kidney diseases in accordance with China's situation, while its practicability and feasibility still need further verification and improvement.

Objective To study doctor-patient interest demands satisfaction and its influencing factors of the payment system reform of the new rural cooperative medical care scheme to provide reference for the reform. Methods Cross-sectional survey was conducted from September 2016 to February 2017. Multi-stage stratified random sampling was used in six counties of three provinces in the eastern, middle and western regions of China, and mathematical statistics was applied to analyze the data. Results The doctor-patient overall interest demands satisfaction was high, but the satisfaction was lower both with the income and ability improvement of medical staff and with the benefits of farmers. The influencing factors of the satisfaction of managers in medical institutions included the type of payment, educational level and work unit (P＜0.05). The influencing factors of medical staff's satisfaction included the type of payment, work unit, and working years among others(P＜0.05). The influencing factors of farmers'satisfaction included the type of payment and the average annual income, etc(P＜0.05). Conclusions The core interest demands of both doctors and patients should be valued to enhance their satisfaction. Diseases related groups should be promoted and applied scientifically, and appropriately integrated with other methods of payment. Both doctors and patients'understanding of the payment reform should be improved by propaganda and training, to get their support and cooperation.
