OBJECTIVETo evaluate the role of the combined periodontic-orthodontic treatment in the esthetic reconstruc- tion of the anterior teeth area following periodontitis.
METHODSThirteen adult patients with anterior teeth displacements were treated. The probing pocket depth (PD; 102 teeth, 612 sites), bleeding on probing (102 teeth, 204 sites), papilla index (PI; 128 papillae), and papillary height (PH; 128 papillae) of each patient were assessed at baseline, 3 months after the initial therapy, and the end of the orthodontic treatment. Non-parametric and paired-sample t tests were carried out for the statistical analysis of the data.
RESULTSThree months after initial therapy, the sites with PD ≤ 3 mm accounted for 79.58% (487/612) of the observed teeth, and 88.73% (181/204) of the buccal and lingual sites of the teeth showed negative bleeding on probing. These findings were better than those at baseline [26.31% (161/612) and 22.06% (45/204), respectively] (P < 0.05), but no sig- nificant difference was observed compared with pro-orthodontic treatment (P > 0.05). Prior to orthodontic treatment, the levels of the PI of 8 and 21 papillae were III and II, respectively, among the 128 observed papillae. After the orthodontic treatment, 51 papillae were at level III and 68 papillae were at level II. The PH of the 102 papillae was 2.84 mm ± 0.62 mm after ortho- dontic treatment. This result indicated significant difference compared with that of pre-orthodontic treatment (1.69 mm ± 0.57 mm) (P < 0.05).
CONCLUSIONAfter initial therapy, moderate orthodontic teeth movements may reconstruct the interproximal soft tissue, with esthetic improvement of the papillary level and resolution of the periodontal defects.

Objective To explore the effect of in utero exposure to inlfammation on innate immune response in preterm infants. Methods Forty-seven premature infants with gestational age<35 weeks were recruited in this study. According to his-tological evidence of placental infection, all neonates were divided into intrauterine inlfammation positive group and negative group. Mononuclear cells and monocytes were isolated from umbilical cord blood, and were cultured in vitro in the presence or absence of LPS (100 ng/ml). The levels of interleukin 1β(IL-1β), interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-α) and interleukin 10 (IL-10) in cord blood plasma and monocyte cultural supernatants were measured by ELISA respectively. The level of IL-1β, TNF-α, IL-6 and IL-10 mRNA were detected by Real-time PCR. Expression of HLA-DR on surface of CD14+monocytes and ratio of CD3+CD4+/CD3+CD8+T was analyzed by lfow cytometry. Results (1) The level of cord plasma IL-6 in intrauterine inlfammation positive group was signiifcantly higher than in negative group. (P=0.02). (2) After stimulation of LPS, levels of IL-1β, IL-6, TNF-α, IL-10 in supernatants were increased signiifcantly, in consistence with their mRNA expression (P<0.05) in both groups. (3) Expression of HLA-DR on surface of monocytes was signiifcantly decreased after stimulation with LPS in intrauterine inlfammation positive group (P=0.012), but was signiifcantly increased in negative group (P=0.0305). Con-clusions In utero exposure to inlfammation does not suppress the response of monocytes to LPS in preterm neonates, but impairs the antigen presenting function in monocytes.

Objective: To discuss the correlation between myeloid derived suppressor cells (MDSCs) and hepatic trans-planted tumor and to explore new ways to inhibit the development of hepatic cancer. Methods: We established the animal models with H_(22) hepatic carcinoma cells transplanted to the anterior right limb. Then the MDSCs morphology was observed with confocal microscopy and the proportion of MDSCs in blood and spleen was measured with flow cytometry. The 36 mice were divided into three groups: the control group, the low-dose group (2mg/kg) and the high-dose group (4mg/kg). Then As_2O_3 was injected twice a week to the mice before repeating the aforementioned measures. The direct effects of As_2O_3 on MDSCs cultured with H_(22)-ascites supernatant was observed. Results: At 25 days after transplantion, the tumor weight was increased to 5.67g, and the proportion of MDSCs in blood and spleen was increased to 20.46% and 9.50%, re-spectively. There was a positive correlation between hepatic transplanted tumor and MDSCs in blood and spleen and the relative factors were 0.95 and 0.96, respectively (t=-5.270 and 5.939, P<0.05). With the effect of As_2O_3, the proportion of MD-SCs in blood in low-dose group and high-dose group was 11.31% and 10.00% at 28 days after treatment, lower than that in the control group (t=3.193 and 5.486, P<0.05), and there was also a statistical difference between the high-dose group and low-dose group (t=3.066, P<0.05). The proportion of MDSCs in the spleen in low-dose group and high-dose group was 10.90% and 9.04% at 28 days, lower than that in the control group (t=3.586.and 5.279, P<0.05), but there was no statistical difference between the high-dose group and low-dose group (1=1.298, P>0.05). In vitro, the proportion of MDSCs in nutrient fluid was increased to 12.67% at 12 days after treatment with H_(22)-ascites supematant, and was decreased to 7.44% at 18 days after treatment with As_2O_3. Conclusion: The proportion of MDSCs in H_(22) tumor-bearing mice is increased because of tu-mor development. There is a positive correlation between MDSCs and hepatic transplanted tumor. As_2O_3 can decrease MD-SCs and inhibit tumor growth.

Objective:To analyze the clinicopathological characterization of primary esophageal benign tumor (EBT). Methods:A total of 1,058 EBTs were enrolled from 500,000 cases in an esophageal and cardiac tumor biological sample and clinical information data-base of Henan Key Laboratory for Esophageal Cancer Research (1973-2015) in the First Affiliated Hospital of Zhengzhou University. SPSS 21.0 software was applied for data analysis. Results:In this database, 1,058 cases with primary EBTs among the 249,246 esopha-geal tumor patients with detailed clinical and pathological information were identified with an incidence of 0.42%(1,058/249,246). A total of 544 patients were male with an average age of 50±11 years old, whereas 514 patients were female, with an average age of 52± 11 years old. Among the 10 types of EBTs, leiomyoma was the most common type (84.50%, 894/1,058), followed by papilloma (6.90%, 73/1058). Adenoma (0.38%, 4/1,058) was the rarest type. Leiomyoma, gastrointestinal stromal tumor, and neurofibroma mainly oc-curred in male patients. By contrast, lipoma, granulosa cell tumor, schwannoma, and hemangioma mainly occurred in female patients.All five cases of hamartoma occurred only in female patients. Given the incidence of≥50%as the common standard, the common EBT in sequence in young male patients was leiomyoma and gastrointestinal stromal tumor, whereas that in young female patients was granulosa cell tumor and lipoma. The common EBT in sequence in older male patients was papilloma, gastrointestinal stromal tumor, and leiomyoma, whereas that in older female patients was schwannoma, papilloma, leiomyoma, gastrointestinal stromal tumor, and hamartoma. Additionally, lipoma, hemangioma, neurofibroma, and adenoma in male patients and neurofibroma in female patients oc-curred in older patients. The different ages of patients with EBTs (P=0.034) and leiomyoma (P=0.004) had a statistical significance. In these EBTs, leiomyoma, papilloma, gastrointestinal stromal tumor, and schwannoma mainly occurred in the middle esophagus, where-as lipoma mainly occurred in the lower esophagus. The major treatment for EBT in the present study was surgery (57.54%, 492/855), which was followed by endoscopic resection (38.01%, 325/855) and others (4.45%, 38/855). Conclusion:The incidence of EBT is low, with a couple of different histological types. Gender, age, and predilection sites are different depending on the histological types of EBTs. Surgery and endoscopic resection are the major treatment methods.

OBJECTIVETo investigate the possibility of urethral reconstruction with colonic mucosa for the treatment of complex longer urethral stricture (>/= 10 cm).
METHODSFrom October 2000 to September 2001, 6 patients with complex longer urethral stricture were treated with colonic mucosal graft urethroplasty. They had under gone 3 previous unsuccessful urethral repairs on average. Urethral reconstruction with a free graft of colonic mucosa ranged from 10 to 15 cm (mean 12.17 cm). Follow-up included retrograde urethrography, urethroscopy, and uroflowmetry.
RESULTSThe patients were followed up 3 - 14 months postoperatively (mean 7.8 months). Meatal stenosis developed in one patient 3 months after operation needed reoperation. The patient voided very well with urinary peak flow 28.7 ml per second duing follow-up for 12 months postoperatively. The other patients voided well with urinary peak flow greater than 15 ml per second. At urethroscopy, colonic mucosa was macroscopically difficult to distinguish from normal original urethral mucosa in 4 patients over 6 months after the operation.
CONCLUSIONSColonic mucosa graft urethroplasty is feasible for the treatment of complex longer anterior urethral stricture. The technique is useful for urethral reconstruction when penial skin and bladder mucosa are not available.
