BACKGROUND: Schizophrenia is substantially heritable, but specific susceptibility genes remain difficult to be identified. Therefore, it is necessary to explore hereditary markers first.OBJECTIVE: To investigate the relationship between schizophrenia and related vWA allele genes based on the analysis of microsatellite DNA vWA polymorphism.DESIGN: A case-controlled study with schizophrenic patients and randomly selected population as subjects.SETTING: Ward of Dalian Seventh People's Hospital and Molecular Biological Laboratory of Dalian Medical University.between March and July 2002 at Dalian Seventh People's Hospital which specializes in schizophrenia. Schizophrenia was diagnosed according to the diagnostic standard of the third edition of "the American Diagnostic Statistical Manual for Schizophrenic Diseases", and their clinical manifestations were predominantly negative signs. Altogether 123 normal blood samples were collected from random population at the Blood Center of Dalian Red Cross. They all denied psychological ailments and severe systematic diseases, and they had no kinship with each other.METHODS: Heparin anti-coagulation blood samples were collected and PCR compound amplification was carried out with the aid of PE Profiler plus system. Then the products were subjected to electrophoresis and gene detection with ABI310 type gene analysis system so as to calculate the frequency of allele genes; Hardy-Weinberg equation law was used to make coincidence test and linkage analysis of the theoretical frequency and actual one. Schizophrenic patients and random population were compared and relative risk was calculated with RR=Pd × (1-Pc)/Pc × (1-Pd) in order to assess the statistical significance (RR: relative risk; Pd: gene frequency of schizophrenia; Pc: gene frequency of random population). RR > 1 was considered of higher susceptibility while RR < 1 was considered of anti-susceptibility. In this way, we could find out vWA allele genes that had susceptible linkage or anti-linkage with schizophrenic related genes.MAIN OUTCOME MEASURES: Major outcome: Correlation analysis of vWA allele genes in schizophrenic patients and random population. Secondary outcome: The coincidence of vWA allele gene frequency in patients with schizophrenia and random population with what was calculated by Hardy-Weinberg law.RESULTS: Data of the two groups were processed according to the objective and statistically analyzed.① vWA allele gene frequency in patients with schizophrenia and in random population was found to coincide with HardyWeinberg law(P > 0.05).② The positive rate of vWA-14 in schizophrenic patients (17.2%) was obviously different from that in random population (33.3%) (RR=0.415, P=0.014). The positive rate of vWA-17 in schizophrenic patients (31.3%) was found to be significantly higher than that in random population (19.5%) (RR=1.866, P=0.043) while it did not differ significantly in other allele genes (P > 0.05).CONCLUSION: The positive rate of vWA-14 was significantly lower in schizophrenic patients than in random population, indicating that vWA-14locus may be negatively selected in schizophrenia due to some reasons,which may be approximate to anti-schizophrenia genes. Moreover, the higher expression of vWA-17 in schizophrenic patients than in random population suggests that vWA-17 locus is correlated with schizophrenia,which may be approximate to schizophrenia-susceptibile genes.

Objective:To analyze clinical and histopathological characteristics of infantile congenital melanocytic nevi (ICMN) .Methods:Clinical and pathological data were collected from 126 infants with confirmedly diagnosed congenital melanocytic nevi in Department of Dermatology, Xijing Hospital from January 2015 to January 2020, and were retrospectively analyzed. Chi-square test was used for comparisons of enumeration data.Results:Among the 126 patients with ICMN, 68 were males and 58 were females; 109 (86.5%) presented with skin lesions at birth; 73 (57.9%) were 2 - 3 years old at the first clinic visit. The skin lesions occurred on the head and face (76 cases, 60.3%) , trunk (24 cases, 19.1%) or extremities (26 cases, 20.6%) . There were 36 (28.6%) patients with small congenital nevi, 68 (54.0%) with M1-type medium-sized nevi, 13 (10.3%) with M2-type medium-sized nevi and 9 (7.1%) with giant nevi. Of 126 cases of ICMN, 121 (96.0%) had solitary lesions, 5 (4.0%) had multiple lesions, 44 (34.9%) had nevi with coarse hairs, 15 (11.9%) had nevi complicated by papules or hyperplastic nodules, and 6 (4.8%) had satellite lesions. Pathological subtypes included compound nevus (120 cases, 95.2%) , intradermal nevus (4 cases, 3.2%) , and junctional nevus (2 cases, 1.6%) . Under the microscope, the depth of the skin lesions was < 1 mm in 38 (30.1%) cases, 1 - 2 mm in 61 (48.4%) and > 2 mm in 25 (19.8%) , and 45 (35.7%) cases showed nevus cells infiltrating the subcutaneous fat layer or deeper tissues. Among the 126 ICMN lesions, common pathological features included nevus tissue maturation (100%, 2 cases of junctional nevi were excluded) , pigment granules in the stratum corneum (53 cases, 42.1%) , disordered/asymmetric distribution of nevus cells (80 cases, 63.5%) , scattered epidermal nevus cells (91 cases, 72.2%) , pagetoid spread of epidermal nevus cells (67 cases, 53.2%) , melanophages in the dermis (71 cases, 56.4%) , and nevus cells distributed along hair follicles/sebaceous glands (82 cases, 65.1%) . Special pathological features included nevus cells embedded in the vascular/lymphatic vessels (42 cases, 33.3%) , nevus cell lysis (45 cases, 35.7%) , fibromatous changes (25 cases, 19.8%) , involvement of the arrector pilli muscles (31 cases, 24.6%) , and mast cell infiltration (30 cases, 23.8%) . Pathological patterns of ICMN with different clinical features: the incidences of infiltration depth > 2 mm, pigment granules and columnar pigment granules in the stratum corneum were significantly higher in the giant nevi than in the small and medium-sized nevi ( χ2 = 7.93, 10.76, 5.89 respectively, all P < 0.05) ; the incidences of infiltration depth > 2 mm, epidermal spongiosis with scattered nevus cells, nevus cell nests distributed along the hair follicles/sebaceous glands, fibromatous changes and mast cell infiltration were significantly higher in the skin lesions with coarse hairs than in those without ( χ2 = 28.29, 8.11, 6.22, 7.92, 8.19 respectively, all P < 0.01) ; the incidences of pagetoid spread of epidermal nevus cells and atypical nevus cells were significantly higher in the skin lesions with papules/hyperplastic nodules than in those without papules/hyperplastic nodules ( χ2 = 4.92, 6.30 respectively, both P < 0.05) . Conclusions:The clinical and histopathological characteristics of ICMN are unique, and atypical nevus cells are common in ICMN. The diagnosis and treatment of ICMN need to be based on the combination of clinical and pathological characteristics.
