OBJECTIVEThis study aimed to investigate the duration of gingival healing after the stage II surgery of dental implantation for periodontitis patients and to provide clinical guidelines for implant restoration.

METHODSTwenty-nine periodontitis patients who had implantation surgery and achieved osseointegration were operated with stage II surgery (a total of 60 pieces of implants). The height of buccal gingival of each implant was measured twice after the stage II surgery. All implants were measured at the lowest point ofbuccal gingival after one week. The implants were randomly divided into four groups according to the schedule of the next test time: group one at one week from the initial test point, group two at two weeks, group three at three weeks, and group four at four weeks. Each group includes 15 pieces of implants. The amount of the buccal gingival change in each group between the second and first tests was determined, and the data were analyzed statistically.

RESULTSThe amount of gingival change of groups one, two, three, and four was (-0.25 +/- 0.66), (-0.04 +/- 0.52), (-0.70 +/- 0.77), and (-0.74 +/- 1.09) mm, respectively. No significant difference was observed between groups one and two in terms of the amount of gingival changes (P > 0.05). However, a significant difference was found between groups two and three (P < 0.05), and the amount of gingival recession was 0.66 mm. No significant difference was found between groups three and four (P > 0.05), and the gingival achieved stability.

CONCLUSIONThe gingival recession achieves stability at the fourth week (after 28 d) after stage II surgery. At this time, the implant can be restored, and the abutment can be selected according to the amount of gingival change of the periodontitis patient.

Objective To eraluate the methods and results of endoscopic mucosal resections for colonic laterally spreading tumors with early malignant degeneration. Methods The pit pattern was studied with magnitying colonoscopy and mucosal staining technique for colonic laterally spreading tumors (LST) undergoing early earcinatous degeneration. They were removed with endoscopic mucosal resection techniques. A follow-up study was made. Results Eight patients suffering from early carcinoma on top of colonic laterally spreading tumors were followed-up. ① 75% of the lesions were situated in the rectum, sigmoid colon and decending colon. ② 75% of the lesions were larger than 30mm in diameter. ③ 75% of the lesions belonged to Ⅳpit pattern. ④ 62.5% of the lesions were Villous adenomas and 75% of the onalignant change involved the mucosa only. ⑤ All the lesions were completely removed by EMR, ⑥ No local residual lesion, recurrence or metastasis was discovered in all the patients after a mean follow-up period of 20.7 months. Conclusions Most of the early carcinomas originated from colonic LST involved the mucosa only. Endoscopic mucosal resection may be a curative method for the early cancer arising from colonic LST.

Objective To analyze the clinical manifestations and electroencephalogram (EEG)characteristics of agyria-pachygyria for its early diagnosis,treatment and prognosis judgment in clinical practice.Methods The clinical manifestations and EEG features of twenty-four patients with agyria-pachygyria who were diagnosed by CT or magnetic resonance imaging(MRI) at Pediatric Neurology of Children's Hospital of Chongqing Medical University from July 2004 to July 2013 were retrospectively analyzed.Results Of twenty-four patients,eighteen cases were diagnosed as diffuse agyria-pachygyria and six cases were diagnosed as partial agyria-pachygyria.The clinical features were mainly manifested as mental retardation (twenty-four patients),and motor retardation (twenty-four patients),and epilepsy (eighteen patients).All of the twenty-four patients had abnormal EEG pattern which were mainly three tapes.Type Ⅰ had diffused high amplitude alpha and beta activity in all cortical regions,frontal-central,or parietal-occipital region (fourteen patients).Type Ⅱ showed alternating high amplitude bursts with sharp and slow waves (seven patients).Type Ⅲ was characterized by high amplitude spike or sharp wave activity generalized or multifocal distribution and δ,θ wave mixing graphics (twelve patients).Nine of twenty-four patients showed two or three EEG characteristic patterns in an awake-asleep EEG recording.During the follow-up of 1-8 years old,twelve of the thirteen patients who were diagnosed as epilepsy in diffuse agyria-pachygyria had refractory epilepsy,mainly with infantile spasms or Lennox-Gastaut syndrome.One of the five patients who was diagnosed as epilepsy in focal agyria-pachygyria had refractory epilepsy,mainly for partial epilepsy secondary generalized seizures.There was a significant difference between them (P =0.008).Eighteen of twenty patients who had moderate-severe mental retardation or dyskinesia were diagnosed as diffuse a gyria-pachygyria,while two were focal agyria-pachygyria.Both of them had a significant difference (P =0.005).Conclusions Agyria-pachygyria is a brain malformation caused by neuronal migration abnormality.Diffuse agyria-pachygyria is presented with serious clinical manifestations and poor outcome while the clinical manifestation of focal agyria-pachygyria is relatively mild and epilepsy could be controlled by antiepileptic drugs or epilepsy surgery.These characteristics of EEG patterns along with clinical findings could provide important evidence for early diagnosis,timely treatment and prognosis judgment of agyria-pachygyria.

Objective To evaluate the value of diffusion-weighted imaging (DWI)in diagnosing the acute centrum ovale infarction, and also to investigate the pathogenesis of the infarction. Methods All 58 patients underwent conventional MRI and DWI scanning after symptoms’ onset. DWI findings were compared to the findings of T_1WI and T_2WI. Results The sensitivity and specificity in diagnosing the ischemia stroke were 96.4% and 98.8% within 7 days after onset. Of all the cases, 62.1% were associated with the cerebral large-vessel disease and emboligenic heart disease. Only 36.2% had a classic lacunar syndrome but 69.0% had more frequently an abrupt onset of symptoms. Conclusion DWI is of high accuracy for diagnosing centrum ovale infarction and detecting early infarction lesions which are difficult to be displayed in conventional MRI, and very helpful in differentiating the acute from non-acute lesions; symptomatic centrum ovale infarction is suggested to be associated with large-vessel and heart disease which should be distinguished from the lacunar infarcts.

OBJECTIVE:To investigate the utilization of antineoplastic drugs in our hospital. METHODS:A retrospective analysis was conducted on antineoplastics used during 2005-2007 in our hospital in respect of the consumption sum,DDDs and average daily cost etc. RESULTS:Over the 3 years,the proportion of antineoplastics showed a year-on-year increase in consumption sum,with the antitumor plant amedica topping the consumption sum list and Tamoxifen topping the DDDs list for three years. Domestic drugs,injections and drugs on the RDL (reimbursable drugs list for basic medical insurance) showed high DDDs in our hospital. CONCLUSION:The consumption of antineoplastics is basically rational in our hospital,yet its management remains to be further tightened.

OBJECTIVEThis research explores the regulatory role of bone morphogenetic protein 2 (BMP2) in the expression of sclerostin in OCCM-30 cementoblast.

METHODSOCCM-30 cementoblasts were treated with 50 and 100 ng · mL⁻¹ BMP2 for 3, 5, and 7 days. SOST mRNA was detected by real-time quantitative polymerase chain reaction (RT-PCR). Western blot analysis was employed to detect the sclerostin levels in the nucleus. Five groups were prepared for the experiments: control, BMP2, BMP2+dorsomorphin, BMP2+SB202190, and BMP2+PD98059. OCCM-30 was pretreated with BMP2 for 3 and 5 days, and then the sclerostin and SOST mRNA levels were measured.

RESULTSRT-PCR and Western blot analyses showed that BMP2 upregulated the expression of SOST in a concentration-dependent manner. SOST expression increased with time (P < 0.05). Moreover, sclerostin levels of BMP2+dorsomorphin, BMP2+SB202190, and BMP2+PD98059 groups were lower than that of the BMP2 group, and the sclerostin level in BMP2+dorsomorphin group was lowest (P < 0.05).

CONCLUSIONThe upregulation of SOST by BMP2 in OCCM-30 is mainly mediated by the BMP2/Smad signal pathway.

Objective To investigate any correlation between walking capacity, center of mass, and pelvic and hemiparetic lower limb motions in stroke survivors. Methods The kinematic variables studied included maximum walking speed, center of mass ( CoM ), pelvic movements and lower-limb movements on the paretic side. These were examined using a three-dimension motion analysis system as thirty-two post-stroke hemiparetic patients walked without aids. Results Average walking capacity was significantly correlated with lateral shifting of the CoM, with paretic limb hip extension, and with deficient knee flexion motions. There was a significant correlation between lateral CoM shifting and paretic limb hip extension and also deficient knee movement. Conclusions Walking capacity after stroke is associated with the lateral shifting of the CoM, paretic limb hip extension and deficient knee flexion. The lateral CoM shifting was associated with paretic limb hip extension and deficient knee movements.

Objective To investigate the effects of using a catheter balloon to treat crieopharyngeal achala-sia in patients with brainstem lesions. Methods Thirty cases of dysphagia caused by brainstem lesions were diag-nosed as crieopharyngeal achalasia through videofluoroscopy of swallowing.The cases were divided into a treatment group and a control group randomly.The treatment group was treated with balloon dilatation and routine dysphagia re-habilitation training once daily,while the control group was treated with routine dysphagia rehabilitation training only.The treatment end point was either the patient resuming an oral diet or after 4 weeks of treatment.All eases were evaluated videofluoroscopically with a drinking test pre-and pest-treatment.Results After 10 to 24 balloon dilata-tions,10 of the 15 patients in the treatment group regained the ability to take solid food and water orally,thoush 2 of them could take pasty food only.Only 2 of the 15 patients in the control group regained the ability to take common food by mouth,though 5 of them could take pasty food.The other patients had no improvement.There wag a signifi-cant difference between the two groups.The cricopharyngeal aehalasia of 12 patients in the ffeatment group improved from incomplete relaxation/opening to complete relaxation/opening.Pooling and residue in the pyriform sinus or val-leculae was reduced and no misaspiration was observed.In the control group only 7 patients had some improvement.The mesn time for the bolus passing the pharynx after treatment was significantly shortened from 0.23 s to 0.15 s in the treatment group,but not significantly in the control group.Conclusions Catheter balloon dilatation is effective for cricopharyngeal achalasia caused by brainstem injury and is helpful for relieving the symptoms in the pharynx phase and the esophagus phase of dysphagia.
