Objective:To investigate the clinical features and treatment outcome of Kallmann syndrome(KS) caused by fibroblast growth factor receptor-1(FGFR1) gene mutation in 4 patients.Methods:Targeted next-generation sequencing(NGS) was performed on thirty KS and normosmic idiopathic hypogonadotropic hypogonadism(nIHH) patients. FGFR1 mutation was identified in four KS patients. The clinical data, laboratory and imaging examinations, and treatment outcome were retrospectively analyzed.Results:Four male patients, aging from 11 to 22 years old, presented as micropenis, and with olfactory dysfunction. Among them, two had history of cryptorchidism, three had history of cleft lip and palate repair surgery. The most severe patient presented with short stature, left microtia and dental agenesis. FGFR1 heterozygous mutation was identified in all four patients, two were point mutation(p.Y374X; p. E670K), and the other was frameshift mutation(p.S346Yfs*61; p.S723*fs*1). One patient, who started treatment of the pulsatile GnRH pump during his youth, succeeded in having two babies.Conclusion:Patients with Kallmann syndrome caused by FGFR1 mutation presents complex clinical manifestations. Besides dysosmia, micropenis, microrchidia, and delayed pubertal development are the main clinical manifestations in male patients. Symptoms such as cleft lip and palate are helpful for early recognition. Genotyping analysis is crucial to confirm the diagnosis. The pulsatile GnRH pump can produce satisfactory therapeutic effect, but the age of initiating therapy should be carefully considered.

Background The management of Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma (HCC) is controversial due to the early recurrence after curative hepatectomy,and many variables were related to the prognosis.The purpose of this study was to predict the tumor recurrence in early postoperative period of the patients with BCLC stage B HCC.Methods From January 2004 to January 2012,104 patients with BCLC stage B HCC underwent hepatectomy.Clinicopathological factors and follow-up data were statistically analyzed to establish a predicting scoring system.Results The overall survival rates for one,three,and five years were 69.2％,52.7％,and 42.3％,and the disease-free survival rates for one,three,and five years were 52.9％,47.3％,and 37.5％,respectively.The multiple factors analysis showed that the micro-vessel invasion,lymph nodes metastasis,multiple lesions,and the high expression of HMGB1 were independent factors (P ＜0.05).A scoring system was established to predict the early recurrence within one year after the surgery for BCLC stage B HCC,according to the analysis results with a specificity of 85.1％ and a sensitivity of 80.3％.Conclusion Variant clinicopathological factors were associated with early postoperative recurrence for BCLC stage B HCC and recurrence early after hepatectomy was more likely in patients with a higher score of the scoring system.

This study was purposed to investigate the sensitivity and specificity of conventional cytogenetics (CC), nested-reverse transcriptase polymerase chain reaction (nested-RT-PCR) and dual-color/dual-fusion fluorescence in situ hybridization (D-FISH) technique in monitoring the tumor load of chronic myeloid leukemia (CML) during treatment with transplantation. CC, nested-RT-PCR and interphase D-FISH were simultaneously carried out to detect the tumor load of 7 CML patients during treatment with non-myeloablative allogeneic stem cell transplantation (allo-NSCT). 40 specimens from 7 CML patients before and after allo-NSCT were analyzed. The results showed that 29 specimens were Ph (+) with different positive ratio and 3 specimens with lower cells were not analyzed by CC. 36 specimens were bcr/abl mRNA (+) by RT-PCR. 4 specimens from case 1 at 12, 18, 26 and 38 months after allo-NSCT were Ph (-) and bcr/abl mRNA (-), 4 Ph (-) bcr/abl (+) specimens containing 2 from case 1 at 9 and 10 months after allo-NSCT, 1 from case 2 at 15 months after allo-NSCT, 1 from case 3 at 12 months after allo-NSCT showed 5.4%, 0%, 16.5% and 1.5% bcr/abl (+) cells by FISH. 3 specimens with lower cells containing 2 from case 5 at 20 and 60 days after allo-NSCT and 1 from case 7 at 40 days after allo-NSCT were analyzed by FISH and showed 55.0%, 27.5% and 73.5% bcr/abl (+) cells. The Ph (-) bcr/abl (-) specimen from case 1 at 12 months post-allo-NSCT showed 0% bcr/abl (+) cells by FISH. It is concluded that CC can be used as a basic tool to monitor the change of tumor load in CML during treatment. When specimen with lower cells can not be analyzed by CC in early period after allo-NSCT, or result of CC can not evaluate precisely dynamic change of tumor load and when tumor load in treated patient are lower to Ph (-) by CC while bcr/abl mRNA (+) by RT-PCR, FISH must be used to detect precisely tumor load and monitor dynamic change of it. More sensitive RT-PCR is used to monitor tumor load when it is lower to bcr/abl (-) by FISH during treatment.
