OBJECTIVEThis prospective study was to observe the correlation between the mesial papilla's height of single implant-supported maxillary central incisor and the distance from the base of the contact point to the alveolar bone crest.
METHODS56 patients involved in single implant-supported maxillary central incisor were included in this study. The distances from the base of the contact point to the alveolar bone crest in the digital periapical film of maxillary central incisor were measured using the software Planmeca Dimaxis Version 3.3.2. The time of measurements were as follows: The pre-surgical and post-surgical periods, before and after the crown installation, the follow-up examination of more than 0.5 year. To analyze the factor of influencing distance, and the correlation between the distance and the height of gingival papilla during the whole restored period. Correlation analysis between the distance and the height of gingival papilla during the whole restoration was done by the statistical software SPSS 12.0.
RESULTSThe results demonstrated that the ratio of esthetic papilla can achieve 54.5% at the crown installation and 95.5% at the follow-up examination when the distance was between 3 mm and 5 mm. When the distance was between 5 mm and 6 mm, they dropped to 30.0% and 75.0%, respectively. However, when the distance increased to above 7 mm, the papilla could hardly be in an esthetic outcome. There was a significant change of the distance was found during the periods from the post-surgery to pre-restoration, and the scope of the changes was between -0.13 mm and 0.46 mm. A negative correlation was found between the distance and the index of papilla. The correlation coefficient r was -0.715 (P < 0.01).
CONCLUSIONIt is proposed that the pre-surgery distance of maxillary central incisor from the base of the contact point to the alveolar bone crest can be used as one of the important reference indexes to assess and predict the height conditions of gingival papilla.

OBJECTIVETo explore the mucosal protective effect on the quality of gastric ulcer healing.
METHODSGastric ulcers were induced in male rats by serosal application of acetic acid. Rats were gavaged for 14 days with saline, omeprazole (OME), teprenone (TEP) and TEP plus OME starting 3 days after ulcer induction. Then the tissues and blood samples were obtained and measured.
RESULTThe lower ulcer index (UI) and increased ulcer inhibition rate were observed in OME and OME+TEP groups. In TEP and OME+TEP groups, restored mucosa thickness increased, cystically dilated glands decreased, microvessels in connective tissue increased, the secretion of mucus, hexosamine, PGE(2), bFGF were enhanced, the expression of EGFR was increased.
CONCLUSIONTEP can improve the quality of gastric ulcer healing, when combined with OME,the effect is more marked.

OBJECTIVETo study the relationship between the change of coagulation and the clinicopathologic characteristics in patients with gallbladder cancer.
METHODSThe 64 gallbladder cancer patients (GBC group) and 60 cholecystitis patients (control group) had been reviewed from January 2007 to June 2013. The prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib), and thrombin time (TT) had been measured and compared between patients of GBC group and control group. The relationship of coagulation function and prognosis were analyzed.
RESULTSCompared with control group, APTT in GBC group ((29.0 ± 4.2) s) was significantly shortened (t = -4.265, P = 0.000) and PT ((11.5 ± 1.4) s), TT ((15.3 ± 3.5) s), Fib ((4.1 ± 0.9) g/L) were significantly increased in GBC group (t = 2.521, 4.147 and 4.365, all P < 0.05). The level of Fib was higher in patients with medium or poor-differentiated tumor cells (F = 4.069, P = 0.022), lymph metastasis (t = 2.640, P = 0.010) and advanced staging (II-IV) (t = 3.003, P < 0.01) than those of well-differentiated, non-lymph metastasis and early staging (0-I). The ratio of gallbladder cancer with hyperfibrinogenemia (32/64) was significantly higher than control group (11/60, χ(2) = 13.709, P < 0.01). In GBC group, compared with normal Fib patients, hyperfibrinogenemia patients showed significantly difference in clinicopathologic characteristics (χ(2) = 5.851-10.573, P < 0.05). The average survival period of hyperfibrinogenemia patients and normal Fib patients were 8.63 months and 16.73 months. The 1-, 3-year survival rate of patients with hyperfibrinogenemia were significantly lower than those with normal Fib (64.7%, 14.9% vs. 74.9%, 21.1%, P < 0.05).
CONCLUSIONPreoperative plasma level of Fib might be a new promising biomarker in patients with gallbladder cancer for evaluating disease progression and prognosis.

OBJECTIVETo investigate the efficacy and adverse effects of dapoxetine in the treatment of premature ejaculation.
METHODSWe randomly assigned outpatients with premature ejaculation in the proportion of 2:1 to receive 30 mg dapoxetine on demand (n =78) or 50 mg sertraline qd for one month (n = 39). Follow-up was accomplished in 95 cases, 63 in the dapoxetine group and 32 in the sertraline group. We recorded the intravaginal ejaculatory latency time (IELT), clinical global impression of change (CGIC) score, and adverse reactions of the patients and compared them between the two groups.
RESULTSIELT was significantly increased in both the dapoxetine (from [0.87 ± 0.31] to [2.84 ± 0.68] min, P < 0.05) and the sertraline group (from [0.84 ± 0.28] to [2.71 ± 0.92] min, P < 0.05) after medication. Based on the CGIC scores in premature ejaculation, the rate of excellence or effectiveness was 36.5% in the dapoxetine and 37. 5% in the sertraline group, and the rate of improvement was 63.5% in the former and 71.9% in the latter. The incidence rates of dizziness, nausea, headache, and diarrhea were slightly higher (P > 0.05) while those of fatigue, somnolence, and dry mouth significantly higher (P < 0.05) in the sertraline than in the dapoxetine group.
CONCLUSIONOn-demand oral medication of dapoxetine is effective and well-tolerated for the treatment of premature ejaculation.

OBJECTIVETo evaluate the effect of preoperative transarterial chemoembolization (TACE) on hepatocellular carcinoma located in caudate lobe.
METHODSTotally 29 cases of caudate lobe hepatocellular carcinoma admitted from January 2001 to December 2010 were analyzed retrospectively. Among the 29 patients, 23 were male and the other 6 were female. The median age was 52 years. According to receiving preoperative TACE or not, the 29 cases were divided into two groups: preoperative TACE plus surgery (group A, n = 11) and surgery only (group B, n = 18). The surgical results and long-term survival were compared between two groups.
RESULTSAfter TACE, the diameter of the tumour reduced by over 33.3% in 3 patients, 10.0% to 33.3% in 6 patients, and less than 10.0% in 2 patients. The duration of surgery and intraoperative blood loss in group A were (298 ± 39) minutes and (1031 ± 310) ml, respectively. The duration of surgery and intraoperative blood loss in group B were (281 ± 54) minutes and (868 ± 403) ml, respectively. No significant difference was found in terms of these two groups (t = 1.006, P = 0.324; t = 1.223, P = 0.232). In addition, 6 cases in group A developed complications and 4 cases in group B did so. Only one patient died because of postoperative complication, and this patient belonged to group A. No significant difference was found between two groups (χ(2) = 0.028, P = 0.868; χ(2) = 0.633, P = 0.426). The 5-year survival rate was 56.8% in group A and 34.9% in group B. The difference did not reach significant difference (P = 0.132).
CONCLUSIONSFor hepatocellular carcinoma located in caudate lobe, preoperative TACE does not significantly increase the surgical difficulty and impair the safety. In addition, preoperative TACE has the tendency to provide benefit to long-term survival.
