Objective To investigate the effects of genetic factors on the onset of psoriasis. Methods Seven hundred and twenty patients with psoriasis vulgaris were studied by questionnaire. Results① For the male and female patients, the peak ages of the first onset were 20~ 29 and 10~ 19 years, respectively, and the average ages were 27.57? 12.18 and 23.01? 12.40 years, respectively.② In 720 psoriatics, 212 cases (29.4% ) reported to have a family history of psoriasis. The age of onset was earlier in man with family history than that in man without family history (P0.05).④ The heritabilities of psoriasis were 71.07%? 2.05% in first degree relatives and 36.77%? 5.17% in second degree relatives. Conclusion The results show that psoriasis vulgaris may be a multigenic inheritable disease, and the genetic factors play an important role in the pathogenesis.

Objective To analyze genetic types and clinical features with anhi drotic ectodermal dysplasia (EDA). Methods The genetic types and clinical manife stations of 35 patients with EDA in five families were analyzed by genealogical investigation and clinical examination. Results① All patients were males in fam iliesⅠ ,Ⅱ ,Ⅳ andⅤ . The females in these families were recessive carriers. T herefore, the genetic types were X linked EDA. There were 8 males and 6 female s in familyⅢ . The proportion of males to females approximated to 1∶ 1, indica ting autosomal dominant inheritant EDA.② In families with X linked EDA, Types Ⅰ andⅡ were divided according to clinical manifestations of the families. The patients in familiesⅠ andⅣ belonged to typeⅠ , with the characteristics of sp ecial appearances, such as defects in the development of hair and sweat glands, hypophrenia and bad sights. Intelligence and physical development were lower tha n those of general population. However, the patients in familiesⅡ andⅤ belonge d to typeⅡ . It was characterized by sparse hair, hypohidrosis and inborn teeth less or teeth dysplasia. Intelligence and physical development were the same as general population. In the family with autosomal dominant inheritant EDA, patien ts manifested hypohidrosis only, and had no other characteristics.③ Histopathol ogy showed defects in the development of hair follicles and sweat glands in pati ents with X linked EDA, but dysplasia of sweat glands and congenital defect of hair follicles in patients with autosomal dominant inheritant EDA. Conclusion T here are variations in hereditary types and clinical manifestations of patients with EDA.

Objective:This study aims to investigate the method and clinical outcomes of feeding tube placement and periopera-tive nutritional support for esophageal carcinoma patients. Methods:A total of 513 esophageal carcinoma patients who have undergone radical resection and reconstruction by a single operating group between January 2012 and December 2013 participated this study. Feed-ing tubes were inserted via the nasal path of 497 cases and by jejunostomy in 16 cases. Early enteral nutrition (EN) was administered through the feeding tubes 24 h postoperatively with a stepwise increase, whereas supplementation of parenteral nutrition (PN) was ter-minated until total EN. Results:Feeding tubes were successfully inserted in all patients during operation. No death or nutritional and metabolic disorders were documented during the observation period. No differences in anastomotic fistula, pulmonary complication, and incision infection were identified between the nasointestinal and jejunostomy groups (P>0.05). A higher incidence of intestinal ob-struction was observed in the jejunostomy group than in the nasointestinal group (P<0.05). Conclusion:Effective placement of nasoin-testinal tube and early enteral feeding are safe and effective methods for patients who have undergone esophagectomy for esophageal carcinoma.

OBJECTIVETo explore the possible genetic model of psoriasis vulgaris.
METHODSThe complex segregation analysis and heritability calculation were performed with the aid of Penrose method, Falconer regression method and SAGE-REGTL program.
RESULTSIt was found that in 1043 patients with psoriasis vulgaris, 305 patients (29.24%) have the family history of psoriasis, and 738 patients have not the family history. A ratio of s/q approached 1/(square root of q) with Penrose method, and the heritability values of psoriasis in the first-degree and second-degree relatives were 67.04%, 46.6% respectively. By complex segregation analysis, Mendelian, non-major-gene model and environment model were rejected for psoriasis.
CONCLUSIONThe results suggest that psoriasis follows a pattern of polygenetic or multifactorial inheritance rather than single-gene inheritance.

Objective:To observe the clinical effect of ablative fractional CO 2 laser in the treatment of hypertrophic scar in children after burn. Methods:The clinical data of patients with post-burn hypertrophic scar in children who met the inclusion and exclusion criteria in the Cosmetic Clinic and Burn Clinic of the Third People’s Hospital of Bengbu City Affiliated to Bengbu Medical College from January 2019 to March 2021 were collected, and a retrospective study was conducted. All patients were divided into laser group and control group, and laser group was further divided into 1-2 times subgroups and 3-4 times subgroups. The laser group received ablative fractional CO 2 laser treatment 1-4 times on the basis of conventional anti-scar treatment (pressure therapy and topical silicone drugs), and the treatment interval was 1-3 months; the control group only received conventional anti-scar treatment. The color, blood vessel distribution, thickness and softness of scar were scored by Vancouver Scar Scale (VSS), before treatment and 2 months after treatment In the laser group, and at 3 and 6 months in the control group, respectively. The degree of pruritus of the scar was scored with Visual Analogue Scale (VAS). The patient’s satisfaction evaluation is graded as four levels: very satisfied, relatively satisfied, generally satisfied, and dissatisfied. All data were analyzed by SPSS 19.0 software with paired t-test, Wilcoxon rank-sum test or chi-square test according to the type and nature of the data. Results:A total of 103 patients with hypertrophic scars were included, with a total of 134 scars, including 58 males and 45 females; the age was (3.9±3.0) years, range 0-11 years old; the scar area accounted for 4.2%±3.1% of the body surface area; the course of scar was (3.6±2.2) months. There were 72 patients (94 scars) in the laser group, including 29 patients (37 scars) in the 1-2 times subgroup and 43 (57 scars) in the 3-4 times subgroup; 31 patients in the control group(40 scars). (1) Vascular distribution, softness and overall score assessed by VSS in 1-2 times subgroup after treatments were significantly lower than those before treatment ( P<0.05). The thickness, blood vessel distribution, softness and overall score assessed by VSS in 3-4 times subgroup after treatments were significantly lower than those before treatment ( P<0.05). The improvement degree of scar after treatment in each group was different. Compared with the control group, the improvement degree in the 1-2 times subgroup and the 3-4 times subgroup was more obvious ( P<0.05). The improvement degree in the 3-4 times subgroup was better than that in the 1-2 times subgroups ( P<0.05). (2) Compared with before treatment, the VSS scores of scars after laser treatment in different parts were significantly different except for the thickness scores of face and neck, trunk, and upper limbs group ( P<0.05). (3) The degree of pruritus was assessed by VAS method. The pruritus score of the 1-2 times subgroups and 3-4 times subgroups before treatment was (4.86±1.35) points, (4.97±0.93) points, and the pruritus score 2 months after treatment was (1.93±0.99) points, (1.90±0.83) points, the pruritus score improved significantly after treatment, and the difference was statistically significant ( P<0.01). The pruritus scores of the control group at 3 months and 6 months were (4.83±0.82) points and (4.22±0.66) points, and the scores at 6 months were slightly improved compared with those at 3 months, and the difference was statistically significant ( P<0.01). (4) In the laser group, 5 patients (6.9%) had pigmentation after the first treatment, and then gradually subsided; 7 patients (9.7%) had blisters after the second treatment, which healed after dressing change. In the control group, 3 cases (9.7%) had erosions, and the erosions improved after adjusting the pressure appropriately. (5) The overall satisfaction of patients in the laser group was higher than that in the control group [100% (72/72) vs. 80.6% (25/31), P<0.05]. Conclusions:Fractional CO 2 laser has a good effect on the treatment of hypertrophic scars in early childhood burns. It can effectively inhibit scar hyperplasia and improve the degree of itching in patients. The satisfaction of both doctors and patients is high.
