ObjectiveTo evaluate the clinical effectiveness and safety of Bairui Granules （百蕊颗粒） in the treatment of acute pharyngitis with wind-heat syndrome. MethodsA multicenter， double-blind， double-simulation， randomised controlled trial was conducted， in which 162 patients with acute pharyngitis and wind-heat syndrome from 7 centers were recruited， and each center was divided into trial group and control group on the ratio of 2∶1. In the trial group， 108 cases were orally administered with Bairui Granules plus Reyanning Granules （热炎宁颗粒） simulant， and in the control group， 54 cases were orally administered with Reyanning Granules plus Bairui Granules simulant for 5 days， with a follow-up visit on the 6th day. Full analysis set （FAS） analysis and per protocol set （PPS） were used for analysis， respectively. The primary efficacy index was the disappearance rate of sore throat after 5-day treatment； the secondary efficacy indexes were the disappearance rate of sore throat after 3-day treatment， as well as the visual analogue score （VAS） of sore throat before treatment， every day during the treatment， and follow-up on day 6， and the traditional Chinese medicine （TCM） syndrome score was performed before treatment and at the follow-up on day 6. The effectiveness on TCM syndrome was evaluated at the follow-up on day 6， and the changes of vital signs， blood routine， urine routine， liver functions， kidney function， the adverse events before and after the treatment were recorded， and safety analysis set （SS） was analysed. Results162 patients entered the FAS and SS analyses， and 158 cases （105 cases in the trial group and 53 cases in the control group） entered the PPS analysis. FAS analysis showed that the disappearance rate of sore throat after 5-day treatment was 80.56% （87/108） in the trial group and 64.81% （35/54） in the control group， and the difference between groups was statistically significant （χ² = 5.10， P = 0.0239）. PPS analysis showed that the disappearance rate of sore throat after 5-day treatment was 80.00% （84/105） in the trial group and 64.15% （34/53） in the control group， and the difference between groups was statistically significant （χ² =4.85， P = 0.0277）. FAS and SS analyses both showed that the difference in disappearance rate of sore throat between groups on 3-day treatment was not statistically significant （P＞0.05）. Compared with those before treatment， the VAS scores of sore throat were lower in both groups during treatment on day 2， 3， 4， 5， and follow-up on day 6 （P＜0.01）， but the difference between groups at each time point was not statistically significant （P＞0.05）. TCM syndrome scores of both groups at the follow-up were lower than that before treatment， and those of the trial group were lower than those of the control group （P＜0.01）. The cure rate and effective rate of TCM syndrome of the trial group were significantly higher than those of the control group （P＜0.01）. There was no significant difference in blood routine， urine routine， liver function， kidney function between groups before and after treatment （P＞0.05）， and no serious adverse events occured in both groups. ConclusionBairui Granules showed clinical effectiveness in the treatment of acute pharyngitis of wind-heat syndrome， and it could significantly improve the clinical symptoms， accelerate the disappearance time of sore throat with good safety.

Objective:To explore the effect of different HER2 expression levels and gene amplification on the efficacy of immunotherapy in metastatic urothelial carcinoma (UC).Methods:The clinical data of 77 patients with metastatic UC who received immunotherapy from June 2017 to April 2021 after failure to the previous chemotherapy were analyzed retrospectively, including 49 males and 28 females with the median age of 62 years. The primary tumors located in bladder in 28 cases (36.4%), renal pelvis in 25 cases (32.5%) and ureter in 24 cases (31.2%). The common metastatic sites included: lymph nodes (n = 45, 58.4%), lung (n = 40, 51.9%), bone (n = 20, 26.0%) and liver (n = 16, 20.8%). 27 patients with bladder UC received surgery on the primary tumors including radical cystectomy (n = 18), partial cystectomy (n = 4) and transurethral resection (n = 5). 43 patients with renal pelvis or ureteral UC received surgery on the primary tumors including radical nephroureterectomy (n = 38), local resection (n = 3) and palliative resection (n = 2). Postoperative intravesical chemotherapy was performed in 15 cases, adjuvant radiotherapy was performed in 6 cases. 3 patients who emerged postoperative bladder recurrence received local radiotherapy. 7 patients received radiotherapy and 1 case received microwave ablation to their metastatic sites. All patients had received first-line chemotherapy and 30 patients (40.0%) had received at least second-line treatment including 70 cases (90.9%) with platinum containing chemotherapy. All 77 patients received anti-PD-1 treatment. 38 patients received sequential regimen after failed to the anti-PD-1 therapy, including antibody-drug conjugate (n = 17), chemotherapy (n = 18) and chemotherapy combined with anti-angiogenesis drugs (n = 12). Immunohistochemical (IHC) staining was used to detect the expression level of HER2 protein in the tumor tissues (74 cases from primary tumors and 3 cases from metastatic tumors) obtained from the initial diagnosis. For patients with HER2 IHC (+ + ), the copy number (CN) of HER2 gene was detected by next-generation sequencing (NGS). HER2 copy number amplification [CN (+ )] was defined as CN ≥ 4, and HER2 copy number non-amplification [CN(-)] was defined as CN < 4. HER2 IHC (0) was defined as HER2 negative, IHC (+ ) or IHC (+ + ) / CN (-)was defined as HER2 low expression, while IHC (+ + ) / CN(+ ) and IHC (+ + + ) were defined as HER2 high expression. Chi-square test or Fisher exact test were used to evaluate the correlation between HER2 expression and objective response rate (ORR) after anti-PD-1 treatment. Kaplan-Meier method and log-rank test were used to compare the differences of median progression free survival (PFS) and overall survival (OS) under different HER2 expression status.Results:All the 77 patients received a median of 11 (range: 2 - 45) doses of anti-PD-1 treatment with a median duration of treatment of 6.4 (range: 1.5 - 47.8) months and the ORR was 33.8% (26/77). The median follow-up time was 30.9 months. The overall median PFS time was 5.8 (95% CI: 3.0 - 8.6) months and the median OS time was 23.6 (95% CI: 8.5 - 38.7) months. HER2 IHC tests were performed in 77 patients. HER2 IHC levels of (0), (+ ), (+ + ) and (+ + + ) were found in 33 (42.9%), 19 (24.7%), 20 (26.0%) and 5 (6.5%) patients, respectively. HER2 copy number was detected in 20 patients with IHC (+ + ), while 1 CN(+ ) and 19 CN(-) were found. The ORR of HER2 negative, low expression and high expression patients were 42.4% (14/33) vs. 31.6% (12/38) vs. 0 (0/6) ( P = 0.08), respectively. The median PFS of the three groups were 11.0 months, 3.7 months and 1.8 months, respectively, with significant differences in overall and pairwise comparison( P=0.001). The median OS of patients with HER2 negative and low expression after anti-PD-1 treatment were 23.6 months and 22.7 months, respectively, while the median OS of patients with HER2 high expression had not been reached, with no significant difference in the overall comparison ( P=0.623). Conclusions:For patients with metastatic UC received anti-PD-1 treatment, the PFS of patients with high HER2 expression was significantly worse than that of patients with low or negative HER2 expression. HER2 expression may have potential value in predicting the efficacy of immunotherapy for metastatic UC who failed the previous chemotherapy, which needs further research.

Objective:To establish and evaluate the effect of graded training mode of clinical nutrition nursing in general hospital.Methods:A clinical nutrition nursing group was established, including core management group, quality control group, education and training group and liaison nurse group. Hierarchical training and practice of clinical nutrition nursing was conducted throughout the hospital, and effect of training was evaluated.Results:The nurses' nutrition knowledge increased from (66.60±9.72) to (85.06±7.85) points, nutrition attitude increased from (72.38±5.55) to (92.50±5.10) points, nutrition behavior increased from (66.87 ± 6.83) to (88.76 ± 7.60) points, and the differences were statistically significant ( t values were -15.520, -11.128, -12.238, P<0.01). The nutritional risk screening rate and nutritional intervention rate of patients were improved to 100%, and the academic level of nurses in nutritional nursing was further improved. Conclusion:The application of graded training mode of clinical nutrition nursing can improve nurses' nutritional knowledge and skills, improve nurses' professional and academic level, and improve patient clinical outcomes.

[Abstract] Objective: Elevated levels of soluble PD-L1 (sPD-L1) are associated with worse prognosis of renal cell carcinoma and multiple myeloma. However, the regulatory roles and functions of sPD-L1 in advanced melanoma are not fully understood. This study was designed to evaluate the association between circulating sPD-L1 concentrations and prognosis of patients with advanced acral or mucosal melanoma. Methods: A total of 102 untreated patients with advanced acral and mucosal melanoma admitted to Peking University Cancer Hospital between January 2012 and December 2015 were enrolled in this study. In the meanwhile, peripheral blood samples were obtained from 40 healthy donors. Circulating sPD-L1 concentrations were determined using an enzyme-linked immunosorbent assay. Results: The advanced melanoma cohort included 58 acral melanoma patients and 44 mucosal melanoma patients. The pre-treatment concentration of sPD-L1 (2.91±2.23 ng/ml) in plasma of patients group was elevated as compared with that in healthy donors (0.59 ng/ml). The concentration of sPD-L1 in serum was significantly upregulated in 39/102 (38.2%) patients and significantly associated with increased LDH level (P=0.021) and number of Tregs (P=0.017). The overall survival rates of patients with high or low concentrations of sPD-L1 were statistically different (8.5 months [high level] vs 11.6 months [low level], P=0.022). Conclusion: sPD-L1 concentration is elevated in patients with advanced acral or mucosal melanoma, which may play an important role in predicting prognosis.

[Abstract] Objective: To explore the expression patterns of melanoma lineage antigens and nuclear antigen Ki-67 and their correlations with survival in melanoma patients. Methods: A retrospective analysis was conducted to analyze the pathological data of melanoma patients treated at the Department of Melanoma, Peking University Cancer Hospital from February 2008 to August 2020, mainly including the expression patterns of melanoma lineage antigens (S-100, HMB-45, Melan-A) and Ki-67, demographics, clinical features and survival. The correlation between expression patterns of melanoma lineage antigens, Ki-67 and melanoma-specific survival (MSS) was analyzed. Results: In total, 603 patients were included in this study. The median follow-up time was 47.4 months. The positive rates of S-100, HMB, and Melan-A were 92.8%, 92.1% and 90.0%, respectively. The percentages of patients with melanoma lineage antigen scores (S-100, HMB-45 and Melan-A was scored each, as 1 when positive and 0 when negative) of 0, 1, 2, and 3 were 0.5%, 5.0%, 15.6%, and 78.8%, respectively. The percentages of patients with Ki-67 scores of 0, 1, 2, and 3 were 43.0%, 36.3%, 16.3%, and 4.5%, respectively. Ki-67 was highly expressed in mucosal and progressive melanomas. In a multivariate analysis, Ki-67 expression was an independent prognostic factor for poorer MSS (HR=1.506, 95%CI: 1.248-1.818, P<0.001) as the incidence of MSS event increased by 50% per 25% increase in Ki-67 expression, whereas there was no statistical correlation between melanoma lineage antigen expression and MSS (HR=0.991, 95%CI: 0.759-1.293, P=0.94). Conclusion: High expressions melanoma lineage antigens are ubiquitous in melanoma tissues, and Ki-67 is an independent prognostic factor for MSS.

Objective:To explore the clinical characteristics of juvenile-onset ankylosing spondylitis.Methods:Clinical data of 350 cases of ankylosing spondylitis diagnosed in Beijing Jishuitan Hospital from January 2014 to December 2019 were collected. There were 75 cases with the symptom onset in age ≤16 years (juvenile-onset ankylosing spondylitis, JoAS), and 275 cases with the symptom onset in age>16 years (adult-onset ankylosing spondylitis, AoAS). The clinical characteristics of two groups were analyzed.Results:Compared with AoAS, JoAS had a higher proportion of males [98.7% (74/75) vs. 79.6% (219/275); χ 2=15.65, P<0.01] and longer course of disease [11(8,15) vs. 8(4,15) years; Z=-3.09, P<0.01]. Compared with AoAS, JoAS was more prone to have peripheral joint swelling and pain [45.3%(34/75) vs. 18.9%(52/275), χ 2=22.20, P<0.01], hip pain [26.7%(20/75) vs. 15.3%(42/275), χ 2=5.25, P=0.03] or heel pain [9.3%(7/75) vs. 2.9%(8/275), χ 2=5.93, P=0.02] as the first clinical manifestation. Compared with AoAS, JoAS had a higher incidence of radiological hip involvement [77.3%(58/75) vs. 43.3%(119/275), OR=4.71, Wald=25.60, P<0.01], lower bone mineral density than peers [34.7%(26/75) vs. 23.3%(64/275), OR=2.23, Wald=7.20, P<0.01], higher incidence of malnutrition [25.3%(19/75) vs. 13.8%(38/275), OR=2.16, Wald=5.84, P=0.02] and higher incidence of acute uveitis [17.3%(13/75) vs. 6.5%(18/275), OR=2.72, Wald=6.24, P=0.01] after adjusting the course of disease. Conclusion:Compared with adult-onset ankylosing spondylitis, juvenile-onset ankylosing spondylitis is more prone to have peripheral joint swelling or hip pain as the first clinical manifestation; the radiological hip involvement, lower bone mineral density than peers, malnutrition and uveitis are more likely to occur.

Objective:To explore the prognostic value of PD-L1 expression level in patients with metastatic renal cell carcinoma (mRCC).Methods:The clinicopathological and survival data of patients with mRCC in our hospital from Jan 2014 to Apr 2016 were retrospectively analyzed including 46 males and 15 females. The median age of these patients was 56 years(range: 29-75 years), with 41 patients ≤60 years and 20 patients >60 years. The baseline data before the systemic therapy showed 36 patients(59.0%)had 1 metastatic organ and 25 patients (41.0%) had equal or more than 2 organs to be metastasized. Among them, 17 patients(27.9%)had lung metastasis and 54 patients(88.5%)had liver metastasis. Abnormal baseline LDH occurred in 4 patients and 52 patients had normal LDH. Favorite and intermediate risk patients categorized by MSKCC risk stratification accounted for 59.6%(34 patients)and 40.4%(23 patients), respectively. Six patients(9.8%)experienced distant metastasis at initial diagnosis, with 4 of them undergoing primary site resection, and the other 55 patients undergoing radical nephrectomy. PD-L1 expression was detected by the immunohistochemical staining method. PD-L1 staining rate ≥1% detected on the tumor cell membrane was defined as positive expression. The correlation between PD-L1 expression and clinicopathological characteristics were compared. Kaplan-Meier method and log-rank test were used to compare the differences about DFS and OS under different factors. Cox proportional hazards regression model is used for multivariable analysis of survival data.Results:The detailed pathological types of the 61 patients with renal cell carcinoma were classified as 53 clear cell carcinomas, 3 papillary carcinomas, 1 collecting duct carcinoma, 2 translocation renal cell carcinomas and 2 being unclassified. There were 4, 20, 19 and 9 patients categorized as WHO/ISUP nuclear grade 1, 2, 3 and 4, and 26, 12, 20 and 2 patients were categorized as T 1, T 2, T 3 and T 4 stage, respectively. Five patients had regional lymph node metastasis(N+), and the other 56 patients had no regional lymph node metastasis(N-). The numbers of patients categorized as stage Ⅰ, Ⅱ, Ⅲ and Ⅳ diseases according to TNM staging system were 20, 11, 21 and 8, respectively. The total PD-L1 positive rate was 24.6%(15/61). The corresponding PD-L1 expression rate of patients with WHO/ISUP nuclear grade 1-4 were 0(0 patient), 5.0%(1 patient), 31.6%(6 patients)and 44.4%(4 patients), respectively; With the increasing WHO/ISUP nuclear grade, the positive rate of PD-L1 gradually escalated with a linear correlation ( P=0.006). The PD-L1 expression of the normal and abnormal LDH group were 19.2%(10 patients)and 75.0%(3 patients), respectively, with significant difference( P=0.035). Univariate analysis of disease-free survival time(DFS)showed that the prognostic factors include PD-L1( P=0.045), age group( P=0.014), WHO/ISUP nuclear grade( P<0.001), T stage( P=0.015), N stage( P=0.026)and TNM stage( P=0.005). However multivariate analysis only suggested WHO/ISUP nuclear grade as the independent prognostic factors for DFS( HR=1.8, 95% CI 1.1-2.9, P=0.018). Either in univariate or multivariate analysis, PD-L1 was not a prognostic factor for overall survival (OS)of mRCC patients(univariate analysis: P=0.154; multivariate analysis: P=0.902). The independent prognostic factors of OS include WHO/ISUP nuclear grade( HR=3.0, 95% CI 1.1-8.0, P=0.033)and MSKCC risk stratification( HR=5.9, 95% CI 1.2-29.7, P=0.03). Conclusions:This study showed that the higher the WHO/ISUP nuclear grade of patients with mRCC, the higher the positive rate of PD-L1. PD-L1 expression was not the independent prognostic factor for DFS or OS of mRCC.

Objective: To investigate the clinical characteristics, treatment methods, and prognosis of metastatic papillary renal cell car-cinoma (pRCC). Methods: The clinical data of metastatic pRCC patients treated at the Department of Kidney Cancer and Melanoma, Pe-king University Cancer Hospital, were retrospectively analyzed. The prognosis of these patients was stratified through international metastatic renal cell carcinoma database consortium (IMDC) model. Survival and influencing factors were further analyzed using the Kaplan-Meier method and Cox proportional risk regression model. Results: From January 2003 to March 2018, 93 patients (median age, 50.0 years) were diagnosed with metastatic pRCC: 89 (95.7%) typeⅡcases and 4 (4.3%) typeⅠcases. The median follow-up dura-tion was 23.1 months, with 90, 44, and 14 patients having received first-line, second-line, and third-line treatments, respectively. The median overall survival (OS) of the 93 patients was (31.5±5.9) months [95% confidence interval (CI): 19.9-43.1], while the median OS of patients with low-, intermediate-, and high-risk (classified as per the International Metastatic Renal Cell Carcinoma Database Con-sortium [IMDC]) were (100.0±32.8), (38.3±8.2), and (16.4±1.2) months, respectively (high-risk vs. low/intermediate-risk, P<0.001; low-risk vs. intermediate-risk, P=0.015). The median progression free survival (PFS) with first-line treatment was (6.6±0.5) months. And the median PFS of the corresponding three groups stratified by IMDC score were (17.5±5.7), (7.1±2.3), and (5.2±1.5) months, respectively (high-risk vs . low-risk, P=0.002; high-risk vs . intermediate-risk, P=0.01). Conclusions: Metastatic pRCC is noted to have unique biologi-cal characteristics. The IMDC model can be used to predict the efficacy of first-line treatment using tyrosine kinase inhibitors as well as the prognosis of metastatic papillary renal cell carcinoma in such patients.
