Objective:To observe the clinical effect of mind-refreshing and orifice-opening needling method plus swallowing disorder therapeutic apparatus for deglutition disorder of stroke patients in convalescence stage.Methods:A total of 136 patients conforming to the inclusion criteria were randomized into three groups by the random number table,including group A of 46 cases,group B of 44 cases and group C of 46 cases.Patients in group A received swallowing disorder therapeutic apparatus treatment,patients in group B received mind-refreshing and orifice-opening needling method treatment,and patients in group C received mind-refreshing and orifice-opening needling method plus swallowing disorder therapeutic apparatus treatment.The treatment was given once a day for 10 d as a course,the whole treatment lasted for 4 courses.Therapeutic evaluation items including water-swallowing test (WST),standardized swallowing assessment (SSA) and modified Barthel index (MBI) were measured before treatment,after treatment and at follow-up visit (2 months after treatment).Results:After treatment,scores of WST and MBI in all three groups increased significantly (all P＜0.05),while the SSA score dropped significantly (all P＜0.05).After treatment and during follow-up visit period,score of WST in group C was significantly higher than that in group A and group B (both P＜0.05),while the difference between group A and group B showed no statistical significance (P＞0.05);the SSA score in group C was substantially lower than that in group A and group B (all P＜0.05),the difference between group A and group B showed no statistical significance (P＞0.05);the MBI scores in group B and group C were substantially higher than that in group A (all P＜0.05),the difference between group B and group C showed no statistical significance (P＞0.05).After treatment and during follow-up visit period,the differences in overall therapeutic effect between group A and group B showed no statistical significance (P＞0.05),while the overall therapeutic effect in group C was substantially better than that in group A and group B (all P＜0.05).Conclusion:Both mind-refreshing and orifice-opening needling method and swallowing disorder therapeutic apparatus can alleviate symptoms of deglutition disorder of stroke patients respectively,and the combination of two methods can improve the therapeutic effect.

OBJECTIVETo explore the therapeutic effects of internal fixation with Herbert screws for the treatment of Pipkin type I and type II femoral head fractures.

METHODSFrom January 2008 to December 2012, 23 patients with Pipkin type I and type II femoral head fractures were treated with open reduction and internal fixation by Herbert screws through Kocher-Langenbeck approach. Twenty-three patients (aged 18 to 52 years with a mean of 35.5 years, including 18 males and 5 females patients, 8 left hips and 15 right hips) with femoral head fractures and posterior hip dislocation. The fracture was classified according to Pipkin classification based on the radiographic findings, 5 patients had type I and 18 had type II fractures. The duration time from admission to the operation ranged from 6 to 72 h (averaged 32 h). The clinical and radiographic outcomes of the patients were measured using Thompson-Epstein scoring scale. The Harris hip score(HHS) was used to evaluate and compare hip functions at the latest follow-up between affected and healthy sides.

RESULTSAll the patients were followed up, and the duration ranged from 20 to 48 months (averaged 30 months). According to Thompson-Epstein system, 12 patients got an excellent result, 6 good, 4 fair and 1 poor. The average HHS at the finial follow-up was 87.80 ± 8.46 (ranged from 66 to 95), which is similar to that in the healthy side 90.10 ± 6.35 (ranged from 72 to 98) (t = 1.044, P = 0.302). The complications such as deep infection, and deep vein thrombosis were not found. At the 3rd year during follow-up,4 patients had avascular necrosis of femoral head. At the 1st year of follow-up, 1 patient had hip pain after walking,screws loosening and shift after trauma,and serious complications of traumatic arthritis. All the 5 patients were treated with total hip arthroplasties.

CONCLUSIONThe treatment of internal fixation with Herbert screws through the Kocher-Langenbeck approach is effective for Pipkin type I and type II femoral head fracture. The method is reliable and valuable for recommendation. However, such fracture may have avascular necrosis of femoral head and complication of traumatic arthritis, which should be observed carefully in clinic with preparation of the prevention and treatment measures.

Objective : To understand the current situation and characteristics of narcotic drugs and psychotropic drugs abuse or dependence among hospital patients and to provide reference for strengthening the management of narcotic drugs and psychotropic drugs. Methods : We collected clinical data from hospitals in Shandong and Guizhou provinces in 2016 and selected patients with history of narcotic drugs and psychotropic drugs. We investigated them through telephone or face-to-face interview,then described the characteristics of demographic information and abuse or dependence of narcotic drugs and psychotropic drugs in diagnosed drug abusers. Results : A total of 280 patients with drug abuse or dependence were recruited,of which 223 cases from nine hospitals in Shandong and 57 cases from five hospitals in Guizhou. There were 170 male patients,accounting for 60.71%; 193 patients aged 45 years and above,accounting for 68.93%; 223 married patients,accounting for 80.51%; 166 patients with a education level of junior high school and below,accounting for 61.25%; 125 patients engaged in agriculture,accounting for 48.64%. Benzodiazepine was the main drugs abused or dependenced by hospital patients,accounting for 73.57%（206 cases）. There were also 83 cases of polydrug abuse,accounting for 29.64%. Among the patients with drug abuse or dependence,45.71% had no special feelings,41.07% had symptoms or felt uncomfortable after withdrawal; 64.64% was for improving their sleep quality. Conclusion Most patients with abuse or dependence of narcotic drugs and psychotropic drugs are middle- or senior-aged and have polydrug abuse. Benzodiazepine are the main abused drugs. The common reason for narcotic and psychotropic drug abuse or dependence is to have a good sleep.

OBJECTIVETo examine the effect of pre-surgical orthodontics on the outcome of the secondary alveolar bone grafting in the patients with complete cleft lip and palate.

METHODSSixteen complete cleft lip and palate patients (9 males and 7 females) with collapsed upper arch or severe mal-positioned upper incisors were selected. The cleft was not easily grafted because of the poor access. The total cleft sites were 22 (10 patients with UCLP and 6 patients with BCLP). The age range of the patients was from 8 to 22 years. Pre-surgical orthodontic treatment was mainly to expand the collapsed upper arch and correct the mal-positioned upper incisors. After the secondary alveolar bone grafting, the patients were followed up and anterior occlusal radiograph/intraoral panograph were taken regularly. The observation period was from 6 months to 4 years. Bergland criteria were used to evaluate the interdental septal height.

RESULTSUpper arch expansion and the correction of the mal-positioned upper incisors done by the orthodontic treatment made the bone grafting procedure easier. The clinically successful rate reached 86%.

CONCLUSIONThe severe upper arch collapse and mal-positioned upper incisors in the patients with complete cleft lip and palate should be corrected orthodontically before the secondary alveolar bone grafting.

OBJECTIVEto evaluate the corrosion resistance of a new titanium alloy for dental restoration in artificial saliva.

METHODSin simulated oral environment, the electrochemical behavior of a new titanium alloy (Ti-12.5Zr-3Nb-2.5Sn) for dental restoration based on the d-electron alloy design method with high elastic modulus, high mechanical and good biological safety properties was investigated together with that of Ti-6Al-4V and TA2 as control groups. The anodic polarization curve and polarization resistance of these alloys were analyzed and the element release of Ti-12.5Zr-3Nb-2.5Sn and Ti-6Al-4V alloy after immersion in artificial saliva for 1, 2, 3, 5, 7, 15 d were measured.

RESULTSpolarization curve indicated that Ti-6Al-4V alloy had lower breakdown potential (0.8 V) than Ti-12.5Zr-3Nb-2.5Sn alloy did (> 2.5 V). Ti-6Al-4V alloy showed higher passivation current density (1.45 × 10(-4) - 1.09 × 10(-3) A/cm(2)) than Ti-12.5Zr-3Nb-2.5Sn alloy (3.32 × 10(-6) - 3.46 × 10(-5) A/cm(2)) and TA2(5.03 × 10(-6) - 2.65 × 10(-5) A/cm(2)) did. Polarization resistance results showed that polarization resistance volume of TA2, Ti-12.5Zr-3Nb-2.5Sn alloy and Ti-6Al-4V alloy were 371.0, 252.0, and 60.1 kΩ×cm(2) respectively. With the increasing of dipping time in artificial saliva, the ion release of Ti-12.5Zr-3Nb-2.5Sn alloy and Ti-6Al-4V alloy increased to different degrees. Ti-6Al-4V alloy always showed more ion release than Ti-12.5Zr-3Nb-2.5Sn alloy did in the experiment.

CONCLUSIONSdata from this study indicated that Ti-12.5Zr-3Nb-2.5Sn alloy, as a dental restoration material, had good corrosion resistance in artificial saliva.

OBJECTIVETo evaluate the accuracy of mammography in breast cancer screening in Asian women.

METHODS8718 community women in Chengdu were examined by mammography during the routine physical examination from Mar. 2002 to Sep. 2007. Pathological diagnosis and following up results were used as the gold standards for X-ray-positive and -negative findings. The sensitivity, specificity and diagnosis odds ratio were calculated as accuracy indexes. Large scale follow-up studies of breast cancer screening in community in Asian women were collected to evaluate the pooled accuracy of mammography. Diagnosis meta-analysis was conducted with Meta-Disc software to estimate the pooled sensitivity, specificity and DOR, and draw the summary receiver operating characteristic (SROC).

RESULTSThe data of seven studies were included with a total of 223 619 women received mammography for screening breast cancer. The sensitivity (95%CI) and specificity (95%CI) of mammography of community-based follow-up study in Chengdu were 0.889 (0.741 - 0.970) and 0.991 (0.987 - 0.993), respectively. Referring to meta-analysis, random effects models were adopted due to existed heterogeneity among studies. The pooled sensitivity, specificity, DOR with their 95% confidence intervals were 0.845 (0.821 - 0.870), 0.930 (0.929 - 0.931) and 117.271 (65.060 - 211.412), respectively. The Area Under the Curve (AUC) of SROC was 0.9144.

CONCLUSIONDue to its high accuracy, mammography deserves to be recommend in breast cancer screening in Asian women.

OBJECTIVETo observe the short-term clinical results of the adjacent segment degeneration after the implantation of Coflex system at the interspinous space of adjacent segment to lumbar fusion.

METHODSFifty patients with grade III disc (Thompson MRI classification) of adjacent segment to lumbar fusion were included and divided alternately into two groups according to the order of hospitalization from January to November 2009. Coflex system was implanted at the interspinous space of adjacent segment to lumbar fusion in 25 patients as Coflex group, the other 25 patients did not have any surgical treatment were as control group. The followed up time was 2 years. Visual analogue scale (VAS) score of low back pain, changes of disc height and motion range of adjacent segment to lumbar fusion on X-ray imaging were evaluated by independent sample t-test or paired samples t-test.

RESULTSThere were 22 patients in Coflex group and 21 patients in control group were followed up 2 years post-operation. The difference of VAS score between two groups was no significance (P > 0.05). In Coflex group, the change of postoperative disc height was no significance (P > 0.05), but the motion range was significantly reduced to 47% of the preoperative value (t = 7.99, P < 0.05). In control group, the postoperative disc height decreased slightly, without significant difference to the preoperative value (P > 0.05). Between the two groups, no differences of the disc height and motion range were found before operation, but the differences of the disc height changes (t = 6.7, P < 0.05) and motion rang (t = -14.5, P < 0.05) were significant in 2 years post-operation. No complications such as Coflex system loosen, immigration and spinal process fracture were occurred.

CONCLUSIONSCoflex system can obviously limit the motion range and maintain the disc space height of adjacent segment to lumbar fusion, and prevent its degeneration in some degree.
