OBJECTIVE:
To compare the efficacy of sublingual immunotherapy (SLIT) with standardized house dust mite extract in mono sensitized and polysensitized children with allergic rhinitis.
METHOD:
One hundred and fifty-seven children who were sensitized to house dust mites and treated with SLIT for house dust mites for at least 1 year were studied. The monoallergen sensitized group included patients who were sensitized to Dermatophagoides pteronyssinus and/or Dermatophagoides farinae (n=92). The polyallergen sensitized group included patients who were simultaneously sensitized to house dust mites and other allergens (n = 65). A standardized extract of house dust mites was used for immunotherapy. Antiallergic medication and the total nasal symptom score (TNSS) were evaluated before and 1 year after SLIT.
RESULT:
One hundred and twenty-five children completed 1-year SLIT. The TNSS improved significantly after SLIT in both groups, with monoallergen sensitized group 11.42 +/- 1.60 vs 3.55 +/- 1.57 (t=30.03, P<0.01), and polyallergen sensitized group 11.54 +/- 1.55 vs 3.23 +/- 1.56 (t=27.76, P< 0.01). But the change in the TNSS did not differ significantly between the groups (TNSS change, 7.94 +/- 2.24 vs 8.32 +/- 2.18, P>0.05). The AMSs were decreased significantly after SLIT in both groups, with monoallergen sensitized group 1.62 +/- 0.44 vs 0.56 +/- 0.37 (t=15.01, P<0.01), and polyallergen sensitized group 1.63 +/- 0.43 vs 0.50 +/- 0.40 (t=13.49, P<0.01). But the AMSs improvement did not differ significantly between the two groups(AMSs change 1.03 +/- 0.58 vs 1.13 +/- 0.61, P>0.05).
CONCLUSION
In polysensitized allergic rhinitis patients, SLIT for D pteronyssinus and/or D farinae produced improvements in both nasal symptoms and rescue medication scores comparable to those in mono sensitized patients. SLIT for D pteronyssinus and/or D farinae should be considered in polysensitized allergic rhinitis patients.

OBJECTIVE:
To explore the effect of rare synonymous variants of the ATP7B gene on the splicing of its precursor mRNA.
METHODS:
A total of 248 rare synonymous variants with allelic frequency of <0.005 were retrieved from the ExAc database. Human Splicing Finder (HSF) was used to predict their effect on the splicing of precursor mRNA. And ESE Finder 3.0 was used to predict the effect of such variants on the binding ability of SR protein family. Rare synonymous variants affecting the binding of two or more SR proteins were selected and verified with an in vitro mini gene splicing report system.
RESULTS:
HSF analysis indicated that 136 of the 248 rare synonymous variants may destroy the exonic splicing enhancer (ESE) motif. Analysis using ESE Finder 3.0 indicated that 19 of them may affect the binding of two or more SR proteins at the same time. In vitro mini gene experiment confirmed that the c.1620C>T (p.L540L) and c.3888C>T (p.A1296A) variants could lead to abnormal splicing of the corresponding exons, resulting in complete skipping of exon 4 and 25% increase in the skipping of exon 18, respectively.
CONCLUSION
Synonymous variants may affect the splicing of precursor mRNA in various ways, particularly the destruction of ESE motif. This study confirmed that the c.1620C>T (p.L540L) and c.3888C>T (p.A1296A) variants can affect the mRNA splicing of the ATP7B gene, resulting in skipping of corresponding exons, which may provide a basis for genetic diagnosis and consultation of carriers.

Objective:To explore the relationship between residual amniotic fluid volume and perinatal outcomes in preterm premature rupture of membranes (PPROM).Methods:The clinical data of each 68 PPROM patients with normal amniotic fluid (group A), less amniotic fluid (group B) and oligohydramnios (group C) were retrospectively analyzed. The delivery modes, perinatal complications, survival of perinatal infants and Apgar score at 1 min and 5 min after birth of live-born neonates were compared among the three groups. Pearson correlation analysis was used to evaluate the correlation between Apgar score of surviving neonates and residual amniotic fluid.Results:There was no significant difference in the incidence of vaginal midwifery and placental abruption among the three groups ( P>0.05). There were significant differences in natural delivery rate, cesarean section rate, incidence of some perinatal complications (amniotic cavity infection, chorioamnionitis, amniotic fluid fecal staining) and perinatal survival rate among the three groups ( P<0.05); There was no significant difference in natural delivery rate and cesarean section rate between group B and group C ( P>0.05); The natural delivery rate in group A was significantly higher than that in group B and C ( P<0.05), and the cesarean section rate was lower than that in group B and C ( P<0.05); There was no significant difference in the incidence of perinatal complications and perinatal survival between group A and group B ( P>0.05); The above perinatal complications in group C were significantly higher than those in group A and group B ( P<0.05), and the perinatal survival rate was lower than that in group A and group B. Using amniotic fluid volume as the independent variable (normal=0, less=1, too little=2) and the above perinatal complications as the dependent variable, logistic regression analysis showed that there was no significant correlation between amniotic fluid volume and the above perinatal complications ( OR=1.029, 1.117, 1.004, 1.045, P>0.05). There were significant differences in Apgar scores at 1 min and 5 min after birth among the three groups ( P<0.05), and the change trend was group A>group B>group C ( P<0.05). Pearson correlation analysis showed that there was a significant positive correlation between Apgar score at 1 min and 5 min after birth and the residual amniotic fluid of pregnant mothers ( r=0.402, 0.371, P<0.05). Conclusions:Residual amniotic fluid volume in PPROM patients is closely related to the degree of neonatal hypoxia, and the reduction of residual amniotic fluid can also increase the cesarean section rate, and oligohydramnios can also affect maternal-infant outcomes, thus it is necessary to pay attention to clinical practice.

The discovery and application of Lanwei (EX-LE 7) was reviewed to elaborate its enlightenment on the inheritance and innovation of acupuncture. Literature published before April of 2017 was searched in CNKI and VIP database with"Lanwei (EX-LE 7)"and"acupuncture"as key words. Related references and publications were retrieved. According to the purpose, literature was screened and key information was extracted to perform systematic review and analysis. The results indicated Lanwei (EX-LE 7), reflection of relationship between organ and body surface under the guidance of acupuncture and meridians theory, was not a point, but an area. The discovery and application of Lanwei (EX- LE 7) was the product of western and Chinese combination. The best indication was simple appendicitis, but operation should be applied once adhesion, purulent and perforation occurred. It is indicated to improve clinical efficacy and avoid accident, the reasoned core of theory system should be insisted and the communication with modern medicine should be reinforced.

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.

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 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.
