China Journal of Chinese Materia Medica 2016;41(2):321-325
To investigate the clinical effect of Gushen Antai pills and progesterone in the treatment of threatened abortion, in order to provide references for early clinical intervention with threatened abortion. The 112 cases of patients with threatened abortion were randomly divided into the control group and the observation group. 56 cases in each group. Patients in the control group was injected with progesterone, the observation group was treated with Gushen Antai pills in addition to the therapy of the control group. Both groups were treated by drugs for two weeks. Their venous bloods (5 mL) were collected before treatment and in 1, 2 weeks after treatment to determine serum levels of β-HCG, P, E2 and CA125. The differences between the two groups after treatment were compared. The total effective rate of the control group and the observation group were 79% and 91.9% respectively, with a statistically significant difference between the two groups (P<0.05). Two weeks after the treatment, the serum levels of P and E2 in the observation group were significantly higher than before treatment, but the serum CA125 levels decreased significantly after treatment (P<0.05). These indicators showed statistically significant difference compared with that of the control group (P<0.05). After treatment, the serum β-HCG levels of the two groups were significantly higher than before treatment (P<0.05), but there was no statistically significant difference between the two groups. Gushen Antai pills and progesterone had a better clinical curative effect in treatment threatened abortion, which could significantly raise serum β-HCG, P and E2, reduce serum CA125 and increase the tocolysis efficiency, and so it was worth promoted in clinic.

OBJECTIVESTo investigate a new targeting mechanical arm for CT-based navigated percutaneous fixation of pelvic fractures, and to evaluate the safety and efficiency of the procedures.
METHODSUsing CT-based 3D navigation software combined with targeting mechanical arm, percutaneous insertion of pelvic models (3 dry human cadaver pelvic skeletons and 5 plastic Sybone pelvic models) were performed, 8 pelvic models allowed percutaneous cannulated screw insertion of both S-I joint (2 S-I screws placement for each side, total 32 screws in this experiment) and both superior ramus (1 ramus medullary screw placement for each side, total 16 screws in this experiment). Percutaneous insertion of pelvic models (4 dry human cadaver pelvic skeletons and 4 plastic Sybone pelvic models, 1 S-I screws and 1 ramus medullary scre placement for each side, 32 screws in this experiment) were performed using fluoro-navigation system (Stryker, USA). Time necessary for every screw insertion were recorded. Accuracy of screw placement was assessed using C-arm imaging and direct eyes inspecting. The time and accuracy of the two methods were compared.
RESULTSThe time required for the CT-based 3D navigation procedure (3.6 ± 1.2) min was significantly less than using the targeting mechanical arm compared to drilling freehand with navigation (9.1 ± 0.8) min (t = 2.50, P < 0.01). There was no significant difference in accuracy between the two methods.
CONCLUSIONCT-based 3D navigation software combined with targeting mechanical arm should be potential to apply percutaneous sacroiliac screwing for pelvic fractures with more accurate and more reliable.

BACKGROUNDComputer-assisted procedures have recently been introduced for navigated femoral neck screw placement. Currently there is little information available regarding accuracy and efficiency of the different navigated procedures. The aim of this study was to compare two fluoroscopic navigation tracking technologies, a novel bi-planar robot navigation and standardized optoelectronic navigation, versus standard freehand fluoroscopic insertion in a Synbone hip model.
METHODSEighteen fixed Synbone hip models were divided into 3 groups. C-arm navigated cannulated screws (AO-ASIF, diameter 7.3 mm) were inserted using freehand targeting (control group). A novel bi-planar robot system (TINAV, GD2000) and an optoelectronic system (Stryker OTS Navigation System) were used for the navigated procedures (robot group and optoelectronic group). Accuracy was measured using radiographic evaluation including the measurement of screw parallelism and decentralization, and joint penetration. To evaluate the efficiency, the number of guidewire passes, operative time and fluoroscopic images taken were noted.
RESULTSThe two computer-assisted systems provided significantly improved accuracy compared to the freehand technique. Each of the parameters, including guidewire passes and number of fluoroscopy images, was significantly lower when using the computer-assisted systems than for freehand-unguided insertion (P <0.05), but operative time was significantly shorter when using freehand-unguided insertion than for the computer-assisted systems (P <0.05). Accuracy, operative time and number of fluoroscopy images taken were similar among the two navigated groups (P >0.05), but guidewire passes in the robot group were significantly less than in the optoelectronic group (P <0.05).
CONCLUSIONSBoth bi-planar robot navigation and optoelectronic navigation were similarly accurate and have the potential to improve accuracy and reduce radiation for freehand fluoroscopic targeting for insertion of cannulated screws in femoral neck fractures. Guidewire passes in the robot group were significantly less than in the optoelectronic group. However, both navigated procedures were associated with time-consuming registration and high rates of failed matching procedures.

OBJECTIVETo evaluate the clinical feasibility and effect of the computer-assisted auto-frame navigation system for distal locking of tibial intramedullary nails.
METHODSThe hardware components of the system included a PC computer with a monitor, auto mechanical stereotactical localization cubic frame, foot holder and localization operative apparatus. Special navigation software can be used for registration of X-ray fluoroscopic images and real-time controlling navigation of tools. Twenty-one cases of close tibial and fibular fractures were treated with closed intramedullary nailing, 6 of which involved in middle third, 12 in middle and lower third, 3 in lower third. C-arm alignment and registration time, fluoroscopic time and drilling time involved in the locking procedure were recorded. The size of unreamed or reamed tibial nails ranged from 8/300-11/330.
RESULTSAll distal holes except 1 were locked successfully. In 9 of 41 locked holes (21.95%), the drill bit touched the canal of locking hole without damage of the nail and clinical consequences. The fluoroscopy time per pair of screws was 2.23+/-0.31 s.
CONCLUSIONSThe computer-assisted auto-frame navigation system for distal locking is well designed, easy to operate and do not need additional instruments during the procedure. The developed system enables the physician to precisely navigate surgical instruments throughout the anatomy using just a few computer-calibrated radiographic images. The total time of X-ray exposure per procedure can be significantly reduced.

Objective:To systematically review the relevant researches on aspiration screening tools for stroke patients. Methods:Literatures aboute stroke aspiration screening tools till December, 2018 were recalled from PubMed, Cochrane Library, Web of Science, EMbase, CNKI, Wanfang Database and China Biomedical Literature Database. Two researchers independently screened the literatures and extracted the basic information, such as the content, screening format, scoring standard and measurement characteristics. Results:A total of 25 studies were included, involving ten aspiration screening tools. The content, screening format, scoring standard and measurement characteristics of the aspiration screening tools were analysed. There was no evidence to support the tools. Conclusion:Tools would be selected according to the patient's condition, age and swallowing related characteristics.
