From March 2004 to March 2005, 43 patients (49 hips) admitted to Department of Orthopedic Surgery, Fushun Central Hospital for minimally invasive total hip arthroplasty (THA) were selected, including 22 male and 21 female aged 22-79 years. All patients underwent THA with cementless prosthesis. The preoperative Harris scores were (46.2?5.3). For comparison, 35 patients (43 hips) were selected undergoing standard THA at the same period, including 22 male and 13 female, aged 31-78 years; 16 patients underwent THA with mixed prosthesis (cementless prosthesis for acetabulum; cemented prosthesis for the femur), and the others with cementless prosthesis. Their preoperative Harris scores were (43.4?4.6). The perioperative bleeding, operation time, incision length, postoperative functional recovery, and prosthetic position were compared. The THA was succeeded in all patients, and all subjects were followed up for 13.1 months averagely. The perioperative bleeding, drainage, blood transfusion and incision length in minimally invasive THA group were significantly less than standard group (P

Objective To analyze the risk factors for traumatic cerebral venous sinus occlusion (CVSO)and to investigate the strategies of early diagnosis of traumatic CVSO. Methods The clinical data of 212 patients with moderate to severe closed traumatic brain injury from January 2012 to December 2015 were analyzed retrospectively. Logistic regression analysis was used to evaluate the risk factors for traumatic CVSO. Results Of the 212 patients with traumatic brain injury, 16.5%(35/212) patients had CVSO. Ten patients had CVSO of thrombotic type (typeⅠ), 16 patients had CVSO of compression type (typeⅡ), and 9 patients had CVSO of mixed type (typeⅢ). Logistic regression analysis showed that skull fracture (OR = 8.141; 95%CI: 3.224-20.840) and epidural hematoma of crossing venous sinus (OR = 3.179; 95%CI: 1.470-7.037) were the risk factors for CVSO, and the former was more significantly correlated with CVSO. Female gender was the risk factor for CVSO typeⅠ(OR =10.425; 95%CI: 1.831-30.053), epidural hematoma of crossing venous sinus was the risk factor for CVSO typeⅡ(OR = 5.766; 95%CI: 1.885-18.197), and skull fracture, epidural hematoma of crossing venous sinus, and the previous history of vein thrombosis was the risk factors for CVSO type Ⅲ(OR =18.005, 4.596, 11.394; 95%CI: 2.021-58.836, 1.144-19.525, 1.436-46.558). Conclusions In the early diagnosis of traumatic CVSO, the crossing venous sinus fracture line and epidural hematoma should be given attention. Attention should be paid to the history of venous thrombosis. MR venography and CT venography contributes to early diagnosis of CVSO.

BACKGROUND: There are many studies on the effect of different experimental parameters on the tetragonal phase of zirconia, but it is unclear whether pH values have effects on the tetragonal phase in hydrothermal reactionOBJECTIVE: To prepare two zirconia systems via hydrothermal method and to regulate the tetragonal phase purity and control the grain size of zirconia (ZrO2) crystal by pH values.METHODS: Analytical reagents Zr(NO3)4?5H2O and Y(NO3)3?6H2O were adopted as reactors, and nano-sized neat ZrO2 and yttria-stabilized tetragonal ZrO2 polycrystal (Y-TZP) powders were synthesized using the hydrothermal method. X-ray diffraction was adopted to characterize the influence of pH values and pH regulators (NaOH solution and ammonium hydroxide/NaOH solution) on phase purity and grain size of tetragonal zirconia.RESULTS AND CONCLUSION: Pure zirconia samples with a grain size lower than 20 nm were obtained through the hydrothermal method, and samples with higher tetragonal phase content compared to monoclinic phase could be derived when the pH value was higher than 10. The optimal pH values for neat zirconia and Y-TZP were 13 and 12,respectively. Furthermore, the ammonium hydroxide/NaOH solution was more favorable to enhance the content of tetragonal zircona. Therefore, the control of pH values and rational choice of pH regulators can improve the tetragonal phase purity and grain size of zirconia.

Objective:To observe the clinical efficacy of electroacupuncture (EA) combined with tuina for chronic tension-type headache (CTTH). Methods:A total of 97 CTTH cases were randomly allocated into an observation group (n=52) and a control group (n=45). Patients in the observation group were treated with EA plus tuina based on pattern identification, whereas patients in the control group were treated with oral amitriptyline and oryzanol. Patients in both groups were treated for 8 weeks. A follow-up was conducted 3 months after the treatment. The intensity, duration, and frequency of the headache were recorded and compared before and after the treatment. Additionally, the patients' psychological state and quality of life (QOL) were compared between the two groups. Results:There were intra-group statistically significant differences in headache intensity score, headache duration, and headache frequency after the treatment and during the follow-up compared with those before the treatment (allP<0.05); and there were between-group statistically significant differences during the same time frame (allP<0.05). The Hamilton depression scale-17 items (HAMD-17) and Hamilton anxiety scale (HAMA) scores were significantly reduced in both groups after the treatment or during the follow-up (allP<0.01); and there were no between-group statistical significances during the same time frame (allP>0.05). The World Health Organization quality of life-BREF (WHOQOL-BREF) scores were significantly reduced in both groups after the treatment or during the follow-up (allP<0.05); and the scores in the observation group were significantly lower than those in the control group (allP<0.05) during the same time frame. The total effective rate was 88.0% in the observation group, versus 71.4% in the control group, showing a significant difference (P<0.05). Conclusion:EA combined with tuina can significantly decrease the frequency of chronic tension-type headache, alleviate headache intensity, shorten headache duration, and improve the patients' wellness. It is better than amitriptyline plus oryzanol.
