BACKGROUND: Calcium phosphate cement (CPC) can strengthen the immediate and early fixation of screws by improving the quality of bone and the surface of screws. OBJECTIVE: To evaluate the biomechanical efficacy of CPC in augmentation of anterior cervical unicortical screw fixation. DESIGN: A study of controlled observation. SETTING: Department of Orthopaedics of First Xiangya Hospital of Xiangya Medical College of Central South University. MATERIALS: Experiments were performed at the Room of Electromechanical Tensile Property of College of Material Science and Engineering of Central South University from September 2003 to January 2004. Anterior cervical unicortical screw (pure titanium) was produced by Zhangjiagang Xinda Medical Equipment Co., Ltd. Injectable calcium phosphate cement was produced by Shanghai Ruibang Biomaterial Co., Ltd. Axial pull-out sleeve was produced by Machine Manufacture Center of Central South University. METHODS: ①Sixteen cervical vertebrae (C3-6) of four fresh young man cadavers with fine results in bone mineral density (BMD) test and sixteen cervical vertebrae (C3-6) of 4 fresh old man cadavers with poor results in BMD test were selected. Specimens were provided by Department of Anatomy of Xiangya Medical College of Central South University. Mortal remains of the deceased were donated according to the will of the dead. Informed consents were obtained from their family members. Twelve vertebrae were selected in each group for three tests. Six vertebrae were selected in pull-out test, and six vertebrae in cyclic bending test and shearing test. Screw holes, which were 8 mm apart from the midline and 5°inclined centrally, were made on both sides in the front part of the vertebra. Cortical bone was not penetrated. ②A screw was randomly inserted into one side hole, which was considered to be a control group. Pull-out test was performed on material testing machine at 5 mm/min. The screw hole was filled with CPC (0.10-0.15 mL) to repair the screw hole, and then the screw was implanted, which was considered to be a restoration group. The screw hole was injected with CPC, and then the screw was implanted, which was considered to be a augmentation group. 24 hours later, pull-out test was conducted again at 37 ℃. ③The screw was randomly implanted into one side hole (as a control group). The screw hole was injected with CPC, and then screw was implanted (as an augmentation group). Both groups received cyclic bending test and shearing test. MAIN OUTCOME MEASURES: ①The maximal axial pull-out strength of screws, ②displacement of screws after cycle bending test, ③the maximal shear strength after cycle bending test. RESULTS: ①The axial pull-out test: In normal vertebrae, axial pull-out strength was (313±64)N, (376±88)N and (446±121)N in the control group, the restoration group and the augmentation group respectively. In osteoporotic vertebrae, axial pull-out strength was (106±47)N, (154±67) N and (191±80)N in the control group, the restoration group and the augmentation group respectively. The axial pull-out strength in the restoration group and augmentation group was significantly bigger than in the control group (P < 0.05). ②The cyclic bending test: The displacement of the unicortical screw in the augmentation group was much smaller than in the control group (P < 0.05). ③ In normal vertebrae, the maximal shear strength was (301±79)N and (395±105)N in the control group and the augmentation group respectively. In the osteoporotic vertebrae, the maximal shear strength was (87±39)N and (149±63)N in the control group and the augmentation group respectively. The maximal shear strength was significantly bigger in the augmentation group than in the control group (P < 0.05).CONCLUSION:CPC can enhance the axial pull-out strength and shearing ability of the screw. The augmentation is more evident in osteoporosis patients.

Objective To evaluate the preoperative sleep quality of inpatients and analyze its influencing factors.Methods A self-designed questionnaire,Pittsburgh sleep quality index(PSQI)and self-rating anxiety scale(SAS)were used to investigate the sleep quality and anxiety of 114 inpatients before operation.The two groups were compared in terms of sleep quality and anxiety.The factors influencing the sleep quality were analyzed.Results Of the 114 preoperative inpatients,72.81%(83 cases)had poor sleep quality.The PSQI scores of preoperative inpatients were significantly higher than that in the healthy individuals,but significantly lower than that in the patients with insomnia(P<0.01).The main factors affecting the quality of sleep were fear of surgery,pain and discomfort,feeling strange with the ward settings,and worry about prognosis,totally causing 89.47%of the sleep disorders. Inpatients with poor sleep quality,37.3%was found suffering from anxiety.The rate was significantly higher than that of patients with good sleep quality(P<0.01).Conclusions The incidence of poor sleep quality is relatively high among the preoperative inpatients, mainly caused by fear of surgery,pain and discomfort.In order to improve the sleep quality,it is necessary to perform psychological and comfort intervention according to the sleep status of the patients.

Objective To investigate the type distribution of urogenital Chlamydia trachomatis(Ct)among STD clinic outpatients in Guangxi Zhuang Autonomous Region, and to estimate the prevalence of Ct infection among the patients during posttreatment follow?up. Methods Urethral and cervical swabs were collected from male and female outpatients with confirmed urogenital Ct infection, respectively, in Institute of Dermatology of Guangxi Zhuang Autonomous Region. The patients with positive results in preliminary screening tests were followed up after treatment, and specimens were collected at follow?up visits. General and clinical information was also obtained from these patients. DNA was extracted from these samples by using the QIAxtractor instrument. Nested PCR was performed to amplify the major outer membrane protein A(ompA)gene for ompA typing, and to amplify CT046(hctB), CT058, CT144, CT172 and CT682 (pbpB) genes for high?resolution multilocus sequence typing (hr?MLST). Then, PCR products were sequenced, and ompA and MLST types of Ct were determined by sequence alignment and MLST analysis, respectively. The obtained MLST sequence types (STs) were compared with those from an Italian population by using the BioNumerics7 software, and a minimum spanning tree(MST)was generated. Results Totally, 44 and 6 Ct?positive specimens were collected at first visits and follow?up visits respectively. Among the 50 specimens, 42 underwent successful ompA typing and hr?MLST, and 7 ompA genotypes and 15 hr?MLST STs were identified, including 3 first reported STs. The distribution of STs of Ct isolates from Guangxi Zhuang Autonomous Region was significantly different from that from the Italian population. Among the 6 followed patients with posttreatment Ct infection, 3 were confirmed to be reinfected with Ct, and the other 3 failed to be diagnosed because of unsuccessful genotyping. Conclusion The genotypes of Ct strains isolated from STD clinic outpatients in Guangxi Autonomous Region were characteristic, and Ct reinfection occurred in some patients during follow?up.
