BACKGROUND:Implanted site and direction of miniscrew implants, post-implantation movement of implants, contact between tooth and implant after tooth movement al can cause root damage.
OBJECTIVE:To investigate the changes of the root surface, periodontal tissue and osteoprotegerin expression in the periodontal tissue at periods of time after miniscrew implant loading.
METHODTwo beagle dogs were selected. For each dog, miniscrews were implanted into the labial alveolar bone near the roots of the maxil ary second, third, and fourth premolars and the maxil ary second, third, and fourth premolars and first molar. Fourteen miniscrew implants were in one dog, including six in the maxil ary and eight in the mandible;two miniscrews of the maxil ary acted as control group with no loading, and the rest miniscrews were as experimental group under orthodontics force. Two weeks after miniscrew implantation, 150 g force was loaded between two miniscrews with nickel-titanium closed-coil springs. The dogs were sacrificed after miniscrews loading 4 and 8 weeks respectively, the teeth were cut completely with alveolar bone tissue and decalcified to make the histological specimen. The histological changes of the root and periodontal tissue were observed by hematoxylin-eosin staining and expression of osteoprotegrin in the periodontal ligament was also inspected by using immunohistochemistry.
RESULTS AND CONCLUSION:When the miniscrews were adjacent to the roots, absorption lacuna occurred in the alveolar bone;after horizontal force was loaded opposite to the roots, alveolar resorption became much more animate. When the miniscrews contacted with the pericementum, some areas of the cement absorbed seriously and even reached the dentin;when sustaining pressure from the miniscrews, the whole layer of the cement absorbed and the dentin was exposed and began to be absorbed. The osteoprotegrin in the periodontal ligament of control group expressed sharply and its expression was notable at 8 weeks;while the osteoprotegrin of experimental group weakly expressed at 8 weeks, and there was significant divergence between control group and experimental group at 8 weeks (P<0.01). The roots and periodontal tissue were al damaged variously after miniscrew implantation adjacent to the roots. When horizontal orthodontic force was loaded opposite to the roots, the expression of osteoprotegrin was influenced slightly;as the loading period prolonged, pressure dramatical y restrained the expression of osteoprotegrin. When discovering the miniscrew implant adjacent to roors, the miniscrew implant anchorage should not be used to load orthodontical force opposite to the roots but ought to be removed in order to leave the root repair autonomously and avoid further damage.

The outpatient service system at Shanghai Sixth People's Hospital came into use since April 2009.Data from Jan.2010 to Oct.2010 and interviews with employees of department in question showed a rapid growth of outpatient appointments,a poor handling of outpatients absenteeism,and poor integration among the platforms of the appointments.The development of outpatient services depends on behavioral change of both medical workers and consumers.Some measures could be employed to improve outpatient appointment within the current mechanism.

Objective To analysis the clinical characteristics, treatment and prognosis for patients with cervical cancer with lymph lode of paraaortic and /or supraclavicular metastasis after combined treatment in two years. Methods Data of 20 patients with lymph lode of paraaortic and /or supraclavicular metastasis of cervical cancer were analyzed retrospectively. Results There was no evidence of lymph node of paraaortic and supraclavicular metastasis before the first combined treatments according to the MRI/CT/SPECT scans in these 20 patients. However, lymph lode of paraaortic and/or supraclavicular metastasis were seen in two years after treatments, the shortest is two months. One patient was progressing during treatment whose pathologic diagnosis is mucinous adenocarcinoma, died in 6 months from treatment start. There was only paraaortic metastasis in 15 patients, among these, 4 patients were found lymph lode of left supraclavical metastasis after retreatments in 3-6 months. Both paraaortic and left-supraclavical lymph node metastasis in 4 cases. Among these 20 cases, recurrence and to give up treatment, whose median survival time is 7.50 months, recurrence and to gain treatment, whose median survival time is 18.98 months, there was significant difference (x2=7.23, P<0.01). Conclusion Patients with cervical cancer with lymph lode of paraaortic and/or supraclavicular metastasis after combined treatment will obviously extend survival time after retretments, which has positive therapy significance.

Objective To investigate the relation between body mass index(BMI),skinfolds(SF)and relative weight(RW),arm girth(AG) and ag e of the children in order to look for the most suitable index used to diagnose children obesity in clinical work.Methods In 1496 healthy children (ranging from 1 to 13 years),their weight, height,AG, triceps skinfold(TSF), sub scapular skinfold(SSF) and abdominal skinfold(ASF) were measured and the relat ion of BMI,SF,RW,AG and age was analyzed.Results 1.Between BMI and the sum of three skinfolds(SF3) ,RW,AG,correlation coefficient was more t han 0.8(P＜0.001).2. With the increase of age, AG and ASF increase wh ile TSF and BMI decrease. 3.Skinfolds in girls of 3～6,12 years of age are thicker t han those in boys;BMI in boys of 8,9 years of age are higher than those in girls .Conc lusions 1.95 percentile of BMI and SF3 as index to diagnose children obes ity is better than single application of RW or one-site skinfold. 2. With the i ncrease of age, AG and abdominal fat increase, but triceps and total fat of body relatively decrease. 3. Fats in girls develop faster than in boys.

Objective To study the relationship between the cancer patients'right to know the true diagnosis and their satisfaction degree with nursing service. Methods We randomly selected 746 patients from the tumor center, the circulation department,the respiration department and surgery department.Questionnaires were designed according to patients'right to know the true diagnosis and the results were analyzed. Results Cancer patients who don't know the true diagnosis wanted to acquire the true information about their diseases but nurses were supposed to keep secret of the actual diagnosis.This contradiction led to the impediment of communication between patients andf nurses compared with other department(P<0.05). Conclusion The right to know their true diagnosis proved to be important for cancer patients in that it could increase the compliance of patients and promote communications so that patients would accept nursing service and the satisfaction degree with nursing service would improved.

Objective To investigate the rule of cell apoptosis after intracerebral hemorrhage (ICH) in rats, and to analyze the effect of Astragalus injection on the brain tissue water content and cell apoptosis perihematoma.Methods Experimental ICH models of rats were produced in by injection of Collagenase into right caudate nucleus using stereotaxis technique. After operation, 160 SD rats were randomly divided into 4 test groups according to different intervention time (operation meanwhile group, 6 h group,12 h group and 24 h group after operation, 32 rats in each group) and hemorrhagic control group (32 rats). The rats in test groups were treated with Astragalus injection intraperitoneally once a day. All ICH animals were killed at 4 d or 7 d after ICH. 12 rats from the above each group were used to measure brain tissue water content (dry-wet method). The effect of different initiation time point of treatment on brain tissue water content and cell apoptosis perihematoma was observed. The apoptosis perihematoma was detected by TUNEL technique.Results Compared with hemorrhagic control group, brain tissue water contents improved significantly in operation meanwhile group (4 d), 6 h group (both 4 d and 7 d) and 12 h group (4 d)(all P
