Results There was no rehabilitation therapist in those medical personnel, and no difference of requirement, referral will and acquaintance of therapy between rehabilitation and acupuncture in CHS （P=0.056，P=0.293，P=0.654）. There was a significant difference in acquaintance of rehabilitation among different ages of medical personnel （P<0.01）, but there wasn't of acupuncture （P=0.104）. Conclusion It still lack rehabilitation therapist in CHS. Techniques and resources were the key points in the development of community-based rehabilitation.

OBJECTIVEThis research aimed to analyze the three-dimensional position of mandibular canal (MC) and man of MC and its relationship with the surrounding structures dibular morphology of normal young males and females by using data from cone beam computed tomography (CBCT), as well as to provide an anatomical basis for clinical surgery of the mandible.

METHODSNormal occlusion and CBCT scans of 29 normal young people were conducted. InVivo 5 software was used to reconstruct the mandible, anchor the points, and measure the jaw shape and three-dimensional course of MC. All measurements were analyzed with SSPS 17.0 software.

RESULTSThe MC lingual bone cortex was thinner than the MC buccal bone cortex, and the distance of the MC to the buccal bone cortex gradually increased. However, the distance of the MC to the tongue bone cortex and alveolar crest gradually decreased from proximal to distal. In addition, the distance of the MC to the mandibular lower margin was minimal at the first molar and reached the maximum at the second premolar. No significant difference was observed among the heights, widths, and thicknesses of the left and right sides of the cortical bone of the mandibular body cross sections. From the midline to the farthest point, the height and lower one-third thickness of the lingual cortical bone of the mandibular body cross sections gradually decreased, whereas the width of the upper cross section and upper one-third thickness of the buccal cortical bone gradually increased. Significant difference was observed in some measured values.

CONCLUSIONAfter MC enter into the mandibular foramen, it moved away from the lingual to the buccal bone but gradually returned to the lingual bone; its general course is closer to the lingual bone. The mandibles of males are thicker than those of females. CBCT can accurately display the course of MC and its relationship with the surrounding structures.

Objective:Using a diagnostic test research,to explore the reliability and validity of the Patient Health Questionnaire (PHQ-9)on screening of depressive disorders in general hospital,and to determine the cut points for depressions with different severities.Methods:Three hundred and nineteen help-seekers (n =319)con-sulting the outpatient department of psychiatry in a general hospital were collected continuously.Among them,80 were people without any psychiatric diagnosis,239 were patients with mental disorders.All of subjects were asked to fulfill PHQ-9,and were assessed by psychiatrist with Mini-International Neuropsychiatric Interview (M.I.N.I.) and Hamilton rating scale for depression.M.I.N.I.was gold standard to diagnose depressive disorder,HRSD was used to assess the illness severity.Result:Factor analysis showed good structure validity of PHQ-9.46 patients were diagnosed depressive disorders.The area under the receiver operator characteristic analysis (ROC)of PHQ-9 was 0.94 (95%CI:0.91 -0.97)for depressive disorders.With 15 as the critical value for depression screening,the sen-sitivity was 0.83 and specificity was 0.90,respectively.By the result of HRSD as the standard to rank different lev-els of depression,the cut points of PHQ-9 for mild,moderate,and severe depression was 6,12,and 15.The consis-tency between results of PHQ-9 (with cut points of 6,12,15)and HRSD was moderate (with kappa =0.49).The kappa between results of PHQ-9 (with recommended cut points of 5,10,and 15)and HRSD was 0.46.Cronbach αcoefficient of PHQ-9 was 0.892.Conclusion:It suggests that PHQ-9 has satisfying reliability and validity,and is applicable for screening depression and assessment of its severity of outpatients in general hospital.The recommen-ded cut points of PHQ-9 are applicable to depressive outpatients in general hospital in China.

Objective To observe the effects of arsenic trioxide (As2O3) on T24 bladder cancer cells growth, Caspase-3 gene expression, as well as the weight and volume changes of transplantation tumor of hairless mouse. Methods The cell proliferation inhibition was measured by MTT colorimetric assay. Morphological changes in the cell nucleus was measured by fluorescein stain. Morphologic cell apoptosis was analyzed by FCM. The espression of Caspase-3 was observed by immunocytochemistry staining. The weight and volume changes of transplantation tumor of hairless mouse were measured before and after As2 O3 was used. Results As2 O3 could significantly inhibit the growth of T24 cells, which depended on the reaction time and concentration of drug. With the extension of the time, the increase in the rate of apoptosis and expression of casepase-3 increased. The tumor size and tumor analysis of As2O3 group decreased than those of the control group(P＜0. 05). Conclusion As2O3 could significantly inhibit the growth of bladder cancer cells and its anti-cancer mechanisms may be related to increased Caspase-3 protein expression.

OBJECTIVE:To compare therapeutic efficacy and safety of lobaplatin or cisplatin combined with tegafur,gimeracil and oteracil potassium in the treatment of advanced metastatic breast cancer.METHODS:A total of 160 patients with advanced metastatic breast cancer were randomly divided into observation group and control group,with 80 cases in each group.Control group was given Cisplatin injection 30 mg/m2 intravenously,every 3 weeks Tegafur,Gimeracil and Oteracil Potassium capsules 50 mg orally after meal,twice a day,for consecutive 14 days.Observation group was given Lobaplatin for injection 30 mg/m2 intravenously,every 3 weeks+Tegafur,Gimeracil and Oteracil Potassium capsules (same usage and dosage as control group),every 3 weeks.A treatment course lasted for 3 weeks,and both groups received 2 courses.Short-term efficacies (ORR、DCR),chemotherapy effects of lymph node,lung,bone and liver,ADR and long-term efficacy were compared between 2 groups.RESULTS:After treatment,ORR(67.50％ vs.46.25％),DCR(85.00％ vs.66.25％),ORR of lymph node metastasis (71.43％ vs.47.83％),ORR of lung metastasis (60.71％ vs.40.00％),DCR of lung metastasis (78.57％ vs.56.00％),ORR of bone metastasis (28.57％ vs.16.67％),1-year survival rates (75.00％ vs.52.50％) and 2-years survival rates (42.50％ vs.17.50％) of observation group were significantly higher than control group;the incidence of chemotherapy ADR in observation group was significantly lower than control group (43.75％ vs.70.00％),with statistical significance (P＜0.05).There was no statistical significance in lymph node metastasis DCR,bone tissue metastasis DCR,liver metastasis ORR and DCR,or half year sarvival rate between 2 groups (P＞0.05).CONCLUSIONS:Compared to cisplatin combined with tegafur,gimeracil and oteracil potassium,lobaplatin combined with tegafur,gimeracil and oteracil potassium show better short-term therapeutic efficacy,therapeutic efficacy of lymph node metastasis,bone metastasis and lung metastasis,more than 1-year long-term therapeutic efficacy and safety in the treatment of advanced metastatic breast cancer.

Objective To investigate the effect of body weight on the induction of mild hypothermia in a rabbit model of asphyxia cardiac arrest. Methods Twenty-four rabbits were randomized into two groups: the ice bag group and the intravenous 4℃ saline group. Cardiac arrest was induced and after 3 minutes of cardiac arrest, cardiopulmonary resuscitation was begun. Simultaneously, mild hypothermia was induced by putting an ice bag over the abdomen or infusion of 4℃ saline via an ear vein. A 2℃ decrease of rectal temperature was considered as the completion of hypothermia induction. Induction times were recorded, compared, and analyzed with respect to body weight. Results All rabbits had restoration of spontaneous circulation (ROSC) and ROSC lasted during the experiment. Induction time in the ice bag group was significantly shorter than that in the intravenous 4℃ saline group (22.8±4.7 min VS 42.5±4.0 min, P< 0.001). Induction time significantly correlated with body weight in the ice bag group (Pearson Correlation: r = 0.725, P = 0.029), but not in the intravenous 4℃ saline group (Pearson Correlation: P = 0.418). Conclusions In a rabbit model, induction of mild hypothermia with an ice bag is faster than with intravenous 4℃ saline; induction time positively correlates with body weight when an ice bag is used, but not when intravenous 4℃ saline used. The effect of body weight should be considered when choosing an appropriate method to achieve early induction of mild hypothermia.

OBJECTIVETo investigate the application of osteotomy template manufactured via 3D printing technique in bilateral sagittal split osteotomy (BSSO).

METHODSThe patient group consisted of 32 patients (17 males and 15 females) with mandibular hypoplasia who underwent a BSSO setback (Hunsuck modification; 64 splits). The mean age at the time of surgery was 23.5 years (range 1.9-35 years). All patients were scanned using cone beam computed tomography (CBCT) to create a 3D model of the mandibular, and the osteotomy template of the inner horizontal ramus of mandible bone incision was manufactured via 3D printing technique. All splits underwent operation with or without the osteotomy template by either a young doctor (attending doctor) or a doctor with extensive orthognathic surgery experience (chief doctor). The time it took to perform the mandible bone incision of the inner horizontal ramus of each group was recorded. Postoperative CBCT scan was performed, and the lingual split scale was used to assess the effect of the operation.

RESULTSPrimary healing of incisions was observed in all patients, and no serious complications occurred. The time it took to perform the mandible bone incision of the inner horizontal ramus was significantly different in the four groups (F=30.059, P<0.05), and it was longer in the group of the attending doctor without osteotomy template than in the other three groups (P<0.05). No significant difference was observed in the other groups (P>0.05). Although all splits (n=64) were performed according to the standardized protocol, only 59.38% (38/64) of the fracture lines run according to the Hunsuck's description. By contrast, only 21.88% (14/64) run through the mandibular canal and 18.75% (12/64) was split. The database was analyzed using crosstabs and via Fisher exact test. The split pattern was influenced by the application of an osteotomy template (P<0.05).

CONCLUSIONThe application of osteotomy template manufactured via 3D printing technique in BSSO was effective, which enabled the young doctor to complete the operation faster and with good results.
