OBJECTIVEThis study aimed to evaluate the morphometric changes in the alveolar bone of the maxillary and mandibular anterior regions after retraction in adolescents.
METHODSThe sample size comprised 30 adolescent patients with class 1 bimaxillary protrusion (12 males and 18 females, age: 12-18 years old) and were treated by extracting four first pre-molars. Cone beam computed tomography (CBCT) was performed 1 month before and 1 month after the retraction. For each maxillary and mandibular anterior tooth, the labial and palatal alveolar plates at cervical 1/3, middle 1/3, and apical 1/3 levels for bone thickness changes during the retraction of the maxillary and mandibular anterior regions were checked. The movements of cervical 1/3, middle 1/3, and apical 1/3 levels of the maxillary central incisor were measured. Statistical analyses were performed with SPSS 16.0.
RESULTSFor the adolescents, alveolar bone thickness increased on the labial side and decreased on the palatal side. The alveolar bone thicknesses of cervical 1/3 and middle 1/3 of maxillary central incisor, cervical 1/3 and apical 1/3 of maxillary lateral incisor, middle 1/3 of mandibular central incisor, apical 1/3 of mandibular lateral incisor, and middle 1/3 and apical 1/3 of mandibular canine all increased after retraction. By contrast, the alveolar bone thickness of the apical 1/3 of maxillary canine and the cervical 1/3 of mandibular canine decreased after retraction. No statistically significant difference was observed in other region.
CONCLUSIONDuring retraction, a controlled tipping movement occur in adolescents. After retraction, the alveolar bone thickness of the labial side increase, whereas that of the palatal side decrease. Moreover, the thicknesses of major areas in the alveolar bone significantly increase.

OBJECTIVETo observe the effectiveness of Bushen Huoxue Decoction in improving the erectile function of male patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI) with stent implantation.
METHODSEighty male CHD patients after PCI with stent implantation were equally assigned to receive conventional Western medicine (control group) and combination of Western medicine with Bushen Huoxue Decoction (treatment group), both for 3 months. Then we compared the pre- and post-medication IIEF-5 scores between the two groups of patients.
RESULTSCompared with pre-medication, the total IIEF-5 score was significantly increased after 3 months both in the treatment group (8.19 ± 2.87 vs 17.83 ± 4.92, P <0.05) and in the control (7.98 ± 2.96 vs 12.18 ± 3.69, P <0.05), even higher in the former than in the latter group (P <0.05), and so were the scores on the 5 specific items (all P <0.05). The total effectiveness rate was 72.5% in the treatment group, significantly higher than 47.5% in the control (P <0.05). No obvious adverse reactions and events were observed during the treatment in either of the groups.
CONCLUSIONBushen Huoxue Decoction can obviously improve the erectile function and the quality of the sexual life of CHD patients after PCI with stent implantation.

Objective To evaluate the clinical efficacy and safety of endovascular treatment for intracranial venous sinus thrombosis based on individual condition. Methods Twelve patients with intracranial venous sinus thrombosis were treated with endovascular management according to the severity and course of disease after they failed to respond to anticoagulant therapy. The clinical signs and symptoms,cerebrospinal fluid pressure and arteriovenous circulation time were observed and followed up (including MRV). Intravenous thrombolysis and mechanical thrombus maceration were carried out in all 12 patients,while intravenous thrombolysis, mechanical thrombus maceration in combination with intra-arterial thrombolysis were employed in 3. After the treatment, anticoagulant therapy was carried out for 6 months.The patients were followed up for 12 to 24 months. Results Of the twelve patients, clinical signs and symptoms included slight headache (2 cases), mild hemiplegia (1 case), ambiopia or blurred vision (3 cases). The cerebrospinal fluid pressure returned to under 26 cm H2O (1 cm H2O =0.098 kPa)following treatment from 28 to 38 cm H2O [ mean (32. 4 ±3.0) cm H2O] in preoperative measurement and the arteriovenous circulation time returned to below 10 s in all patients following treatment. Neither recurrence of thrombosis nor new symptoms of neurologic dysfunction was observed. No procedure-related intracranial or systemic hemorrhagic complications occurred both during and after the operation with the exception of a subcutaneous bleeding at the venopuncture site. Conclusion Endovascular treatment is effective and safe for patients with intracranial venous sinus thrombosis.

retrospective cohort study was adopted.The clinical data of 343 patients with intermediate-stage hepatocellular carcinoma (HCC) who were admitted to the Eastern Hepatobiliary Surgery Hospital of the Second Military Medical University between February 2008 and January 2010 were collected.All the patients received the detailed medical history collection,physical examination,laboratory and imaging examinations after admission,and then hepatectomy was performed according to the results of above examinations.Research methods:(1) patients were allocated into the B1,B2 and B3/4 groups based on the Bolondi's substaging model,and the prognostic analyses among groups were conducted.(2) The related factors affecting the prognosis of patients in the B1 and B2 groups were analyzed.(3) The patients in the B1 and B2 groups were allocated into the 4 groups [patients of B1 group with negative microvascular invasion (MVI) were divided in the M1 group,patients of B1 group with positive MVI in the M2 group,patients of B2 group with negative MVI in the M3 group and patients of B2 group with positive MVI in the M4 group] according to the situations of MVI,and stratified analysis was conducted.Observation indicators:basic clinical and pathological features and survival of patients in the B1,B2 and B3/4 groups were observed.Risk factors analysis affecting the prognosis of patients and stratified analysis of MVI in the B1 and B2 groups were conducted.All the patients were followed up by outpatient examination and telephone interview up to February 2014,and the abdominal ultrasound,liver function and serum alpha-fetoprotein (AFP) tests was performed once every 3 months within 2 years postoperatively and once every 6 months after 2 years postoperatively.The continuous variables and categorical variables were respectively represented as M(Qn) and percentage.The comparisons of continuous variables and categorical variables among groups were analyzed by ANOVA or Kruskal-Wallis test and chi-square test or Fisher exact probability,respectively,and one-way ordinal categorical variables were analyzed by the Kruskal-Wallis test.The survival curve was drawn using the KaplanMeier method.The univariate analysis and multivariate analysis were done using the Log-rank test and COX regression model.Results (1) The basic clinical pathological features:of 343 patients with HCC,143,183 and 17 patients (12 in the B3 substaging and 5 in the B4 substaging) were respectively allocated into the B1,B2 and B3/4 groups.There were statistically significant differences in the age,peritoneal effusion,total bilirubin (TBil),albumin (Alb),alanine transaminase (ALT),prothrombin time (PT),platelet (PLT),alpha-fetoprotein (AFP),extent of liver resection,surgical margin ivasion,tumor diameter,number of tumor,Edmondson-Steiner grade,Up-to-7 score,Up-to-7 standard and Child-pugh score among the 3 groups (F
