BACKGROUND: Frenulum of prepuce of penis contained many nerve terminals is an extremely sensitive region. If the frenulum is injured in circumcision or other operations, the complication, such as postoperative spontaneous pain of penis, sexual disturbance and so on, will occur. But there still is no define explanation for this up to now.OBJECTIVE: To observe the distribution of immunoreactive nerve terminal of calcitonin gene-related peptide (CGRP) in prepuce of penis and frenulum of prepuce of adult SD rats, and look for the source of CGRP immunoreactive nerve terminal in frenulum of prepuce.DESIGN: A single sample trial.SETTING:Department of Anatomy, School of Medicine, Zhejiang University.MATERIALS: The experiment was performed at Department of Anatomy,School of Medicine. Zhejiang University from September 2004 to May 2005. A total of 20 adult male SD rats were selected, and were raised in warm, quiet, photophygous environment for 1 week before the trial so as to make the rats fit for the environment and maintain their basal state.METHODS: The rats were assigned randomly into 2 groups. Ten rats in the first group were treated with the immunohistochemical method to observe the distribution of CGRP immunoreactive nerve terminal in prepuce of penis and frenulum of prepuce of adult rats. Ten rats in the second group were treated with fluorogold (FG) retrograde labeled combined with CGRP immunofluorescence labeled method to look for the source of CGRP immunoreactive nerve terminal in frenulum of prepuce of penis. MAIN OUTCOME MEASURES: ①The morphology and distribution of CGRP immunoreactive nerve terminal in prepuee of penis and frenulum of prepuce of adult SD rats were observed under light microscope. ②The distributive density and difference of CGRP immunoreactive nerve terminal in prepuce of penis and frenulum of prepuce were detected and compared (represented by A). ③Morphology and distribution of FG retrograde labeled -positive, CGRP single-labeled positive and FG/CGRP double-labeled positive neurons in dorsal root ganglion were observe under fluorescence microscope. ④Mean quantity of FG retrograde labeled positive, CGRP single abeled positive and FG/CGRP double-labeled positive neurons in dorsal root ganglion was counted.RESULTS: Totally 20 rats were involved in the analysis of results. ① Amber-coloured CGRP immunoreactive nerve terminal appeared in prepuce of penis and frenulum of prepuce of adult rats. These nerve terminal mainly occurred in basal layer of epidermis and papillary layer of dermis, distributed as twig shape or intestiniform; mostly of them were bundled, different in length, and some of them showed enlarged nodosity. ②The distributive density of CGRP immunoreactive nerve terminal in frenulum of prepuce of penis was significantly larger than that in prepuce of penis (2.15±0.32, 1.02±0.22,t =-2.03,P<0.01). ③Combined with the FG retrograde labeled method it was found that these nerve terminal was derived from neurons of dorsal root ganglion opposed to the sixth lumbar spinal cord and the neurons of dorsal root ganglion opposed to the first acral spinal cord. FG retrograde labeled positive neurons differed in length. The cell body showed round or orbicular-ovate, without obvious prominence. Bright inaurate fine particle appeared in cytoplasm, no label in nucleus. Most cells arranged in line along nerve tract or diffusedly distributed. Most CGRP single-labeled positive neurons were middle or small cells found by CGRP immunofluorescence labeling. Dyeing was too dark.Reaction product distributed evenly in cytoplasm, which showed bright dark green (FITC labeled color). The same positive section was observed comparatively under different excitation light. It was found that FG/CGRP double-labeled positive cells were middle or small, and its amount accounted for a half of the total number of FG retrograde positive cells.CONCLUSION: CGRP may participate the transmission of sensory information in prepuce of penis and frenulum of prepuce of rats. The CGRP immunoreactive nerve terminal in frenulum of prepuce of penis of rats is sourced from neurons of dorsal root ganglion opposed to the sixth lumbar spinal cord and the neurons of dorsal root ganglion opposed to the first sacral spinal cord.

OBJECTIVE:
To evaluate the efficacy of personal sublingual immunotherapy (SLIT) with dermatophagoides to study the efficacy of dermatophagoides farinae drops for allergic rhinitis (AR) of different age groups.
METHOD:
The current study had analyzed the efficacy of SLIT in 150 patients with AR who were sensitized to house dust mites. All patients were treated with dermatophagoides farinae drops and combined with symptomatic treatment. The patients were divided into groups 1-5, group 1:17 patients (4-7 years old), group 2: 38 patients (> 7-12 years old), group 3:31 patients (> 12-18 years old), group 4: 38 patients (> 18 - 40 years old), group 5: 26 patients (> 40-63 years old). The total nasal symptom scores (TNSS) and total medicine scores (TMS) were recorded at each visit. Before and after SLIT for 0.5 year, 1 year and 1.5 to 2.0 years, the TNSS and TMS of each patient were evaluated. The dosage adjustment of immunotherapy according to the patient's symptoms were performed.
RESULT:
The TNSS and TMS had continuously improved significantly after SLIT for half year, 1 year and 1.5 to 2.0 years in all groups as compared with baseline (P < 0.05). There were no significant differences in the different age groups for TNSS and TMS during all time points.
CONCLUSION
Individualized SLIT with dermatophagoides farinae drops for 1.5-2.0 years is the most effective in the patients with allergic rhinitis of different age groups. And equivalent efficacy could be achieved for different age groups.

OBJECTIVETo evaluate Amifostin's effect on protecting kidney from cisplatinum (DDP) injury and its adverse reactions and safety.
METHODS193 Patients were divided into two groups randomly: 102 in group A (treatment group) and 91 in group B (control group). Indexes such as blood routine, blood calcium, liver function, blood urea nitrogen (BUN), cretinine (C), and urinary N-acetyl-beta-D-glucosaminidase (NAG)/C and micro-albumin (MAB/C) were monitored at different intervals before or after treatment.
RESULTSIn the two courses of treatment in both groups, the deviation (D) values of MAB/C before treatment and on D2 in group A were lower than those in grop B (P < 0.05), so were those before treatment and on D4, D6, D10 and D14 (P < 0.01). The D-values of NAG/C before treatment and on D4, D6, D10 and D14 in the first course of group A were obviously lower than those on the corresponding days in group B (P < 0.01), so were those before treatment and on D2, D4, D6, D10 and D14 in the second course (P < 0.01).
CONCLUSIONThe reduction of MAB/C and NAG/C by Amifostin in group A demonstrates that: Amifostin is able to effectively protect the renal function, regardless of the type of tumor. In contrast with group B, Amifostin in group A shows no protection for tumor in lung cancer and ovarian cancer. The main side effects of Amifostin are mild hypotension, nausea, vomiting and hypocalcemia in some patients.

Background and objective Non-small cell lung cancer (NSCLC) has been transformed from the treatment according to histological type to genotype treatment model. The epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) genes are the most important drivers in lung cancer. The aim of this study is to explore the clinical characteristics and prognostic factors of patients with advanced NSCLC with different genotypes. Methods We retrospectively reviewed the clinical data of 553 advanced NSCLC patients with EGFR mutations and ALK positive who were hospitalized in the Beijing Chest Hospital from July 2004 to December 2015, and the independent prognostic factors of pa-tients were analyzed by Cox proportional hazards regression model. Results The clinical data of 553 patients (227 with EGFR mutations, 58 with ALK positive, 2 with EGFR and ALK co-mutation and 266 with wild-type) with advanced NSCLC were enrolled in this study. The median survival time of 227 patients with EGFR mutations was 28.7 mo (95%CI: 22.160-35.240), and the performance status (PS) score (0-1) (HR=4.451; 95%CI: 2.112-9.382; P<0.001) and EGFR-tyrosine kinase inhibitors(TKIs) targeted therapy (HR=2.785; 95%CI: 1.871-4.145; P<0.001) were the independent prognostic factors for the survival of patients harboring EGFR mutations. The median survival time of 58 patients with ALK positive was 15.5 mo (95%CI:10.991-20.009), and treatment with crizotinib (P=0.022) was the independent influence factor for the survival of ALK positive patients. The median survival time of 266 patients with wild-type was 12.1 mo (95%CI: 10.660-13.540), and the PS score (0-1) (HR=2.313; 95%CI: 1.380-3.877; P=0.001) and treatment with chemotherapy (HR=1.911; 95%CI: 1.396-2.616; P<0.001) were the independent prognostic factors for the survival of wild-type patients. Conclusion The prognosis of patients with advanced NSCLC is associated with genetic mutation, and targeted therapy has a improvement on survival for patients with EGFR mutations or ALK rearrangement.

Background and objective Status of epidermal growth factor receptor (EGFR) gene is a predictor of response to EGFR tyrosine kinase inhibitor (TKI). However, lile is know about the relationship between EGFR status and response to chemotherapy. We evaluated the prediction value of EGFR mutation status on response to first-line chemotherapy in patients with advanced non-small-cell lung cancer (NSCLC). Methods e data of 181 patients with stage IIIb/IV NSCLC who diagnosed by histopathology from January 10, 2006 to December 20, 2013 in Beijing Chest Hospital, Capital Medical University were collected. e relationships between EGFR gene status, clinical characteristics and response and progression-free survival (PFS) were analyzed. Results All of the 181 patients’ EGFR statuses were determined. 75 (41.4%) patients har-bored EGFR-activating mutations and 106 (58.6%) patients were EGFR wild-type. All patients received first-line chemother-apy. e objective response rate (ORR) was 26.0% and disease control rate (DCR) was 70.2%. Patients with EGFR-activating mutations had a higher DCR than patients with EGFR wild-type (84.0% vs 60.4%, P=0.001) did. Subgroup analysis showed that the ORR and DCR in patients with EGFR exon 19 deletions were remarkably higher than those with EGFR wild-type (P= 0.049, 0.002, respectively). e DCR in patients with EGFR exon 21 L858R mutation was significantly higher than that in patients with EGFR wild-type (P=0.010). 168 patients were available for response evaluation in all of 181 patients and median PFS was 4.3 mo. e PFS of patients with adenocarcinoma was significantly higher than that patients with squamous cell carci-noma (4.7 mo vs 3.0 mo, P=0.036). e PFS in patients harbored EGFR-activating mutations was significantly higher than that in the patients with EGFR wild-type (6.3 mo vs 3.0 mo, P=0.002). e PFS of patients with a performance status (PS) of 0-1 was significantly higher than that in patients with a PS of 2 (4.4 months vs. 0.7 months, P= 0.016). Cox multivariate analysis indicates the EGFR-activating mutation is an independent factor aecting PFS (HR=0.654, 95%CI: 0.470-0.909, P=0.012). Conclusion EGFR-activating mutation is a predictor for PFS of first-line chemotherapy in advanced NSCLC patients.

Background and objective Activating mutations in epidermal growth factor receptor (EGFR) and KARS are important markers in non-small cell lung cancer. However, EGFR and KARS gene mutations in lung squamous cell carcinoma are rarely reported. hTe aim of this study was to analyze EGFR and KARS gene mutation rate and their relationship with clinical features in patients with lung squamous cell carcinomas. Methods A total of 139 patients undergoing treatment for na?ve lung squamous cell carcinomas with tumor tissue samples available for testing were recruited. EGFR and KARS mutation statuses of the tumor samples were detected using a mutant enriched liquid chip. Results Of the 139 cases of lung squamous cell carcinoma, EGFR mutations were detected in 25 cases (18%), KARS mutations were detected in 7 cases (5%), and the pres-ence of both EGFR and KARS mutations was detected in 1 case (0.7%). EGFR mutations occurred more otfen in females than in males (33.3%vs 16.5%) and in patients that never smoked than in those who smoke (29.6%vs 16.1%). However, the differ-ence did not reach statistical signiifcance (P>0.05). No signiifcant differences were observed in age, stage, and different biopsy type. KARS mutations occurred more otfen in males than in females (5.5%vs 0%), but the difference did not reach statistical signiifcance (P>0.05). No signiifcant differences were observed in age, stage, different biopsy type, and smoking status (P>0.05). Conclusion EGFR and KARS mutations were low in lung squamous cell carcinomas, and had no signiifcant correlation with clinical features. Before using tyrosine kinase inhibitor targeted therapy, EGFR and KARS mutations should be detected in pa-tients with lung squamous cell carcinomas.

Background and objective Kirsten rat sarcoma viral oncogene (KARS) mutation is one of the major driver genes of non-small cell lung cancer (NSCLC). KARS is a resistant predictor of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs), which raises controversy because of its role in chemotherapy sensitivity and prognosis. hTe aim of this study is to accumulate clinical experience in treating NSCLC patients harboringKARSmutation.MethodsA total of 107 NSCLC patients harboringKARSmutation were analyzed retrospectively. hTe effcacy was analyzed in terms of ifrst-line chemotherapy or EGFR-TKIs therapy.Results hTe objective response rate (ORR) to ifrst-line chemotherapy of 52 pa-tients with advanced disease harboringKARS mutation was 9.6%. hTe disease control rate (DCR) was 53.8%, and the median progression-free survival (PFS) was 3 months. hTe ORR to EGFR-TKIs therapy in 21 patients harboringKARS mutation and EGFR/KARS co-mutation was 9.5%; the DCR was 23.8%, and the median PFS was 1 month. hTe ORR and DCR to EGFR-TKIs therapy of patients withEGFR/KARS co-mutation were signiifcantly higher than those of patients withKARS mutation (50%vs 0,P=0.029; 75%vs 11.8%,P=0.043); the median PFS was also signiifcantly longer (3 monthsvs 1 month,P=0.004). Conclusion hTe effcacy to ifrst-line chemotherapy and EGFR-TKIs therapy in NSCLC patients harboringKARS mutation was poor; thus, new drugs should be developed. Furthermore, the existence ofEGFR/KARS co-mutation was conifrmed. Hence, EGFR-TKIs therapy should be administered to patients withEGFR/KARS co-mutation.
