Patients often suffered limb dysfunction after stroke. Upper limb and hand function recovered more slowly than lower limb, and became one of the research focuses in rehabilitation medicine. Timely and effective assessments were important to guide the rehabilitation treatment, evaluate the treatment efficacy and predict functional recovery of upper extremity and hand function. The assessment methods of upper limb and hand motor function included subjective evaluations and objective evaluations. The former included different kinds of scales, which involved assessment focusing on muscle, motor pattern, change of upper limb and hand function. While the latter contained biomechanics, neuroelectrophysiology, functional magnetic resonance imaging, upper limb robotic evaluation system and so on. Scales were proved to have good reliability and validity. But they could not show patients' function accurately because of the subjectivity, and the data could not be kept. Evaluation system with computer was applied in clinical practice more and more widely. In this review, we summarized the assessments on upper limb and hand motor function in patients after stroke.

Objective To understand the status of Toxoplasma gondii(TOX)infection in pregnant women in Qingdao area. Methods Antibody capture ELISA was used to detect the TOX-IgM,IgG and TOX-DNA in 1 341 pregnant women and 201 infer-tility,miscarriage,stillbirth pregnant women from June 2011 to July 2013. Results Among 201 abnormal pregnant women,43 cases were TOX antibody positive,accounting for 22.39%,and among the normal pregnant women,84 cases were TOX antibody positive,accounting for 6.26%,and there was a significant difference(χ2 =10.60,P<0.05). The TOX positive rate of 20-29 years old women was higher than that of the women aged over 30 years(χ2=21.9,P<0.05). The TOX antibody positive rates of families with pets and families without pets were 26.63%and 8.77%respectively(χ2=10.93,P<0.05). The TOX antibody posi-tive rates were 10.94%(22/201)in unemployed women,3.98%(8/201)in farmers,3.98%(8/201)in staff,and 3.48%(7/201)in workers. Conclusions The TOX infection rate in abnormal pregnant women is significantly higher than that in normal pregnancy women;therefore,the health education should be strengthened. In addition,in young women,especially 20-29 years old women, and some special occupation women,the control measures should be enhanced.

Objective To optimize the preparation process of Tangzu Granula. Methods With the paste-forming rate and total content of paeoniflorin as the indexes, the optimal water-extraction condition was screened by orthogonal design. With hydroscopicity, fluidity and formability as the indexes, the appropriate ratio of the excipient and the formula were selected. Results The optimum water-extraction condition was as follows: 10-fold water, decoction for 2 times and 1.5 hour for each time. The optimal ratio of the excipient and the formula for preparation of Tangzu granules were two proportions of the extract and three proportions of the excipient which consisted of lactose and dextrin(2 : 1, w/ w).

Objective: To explore the effect of ultrasound on dentin smear layer's surface and bonding strength of the universal resin adhesive under self-etching mode. Methods: Forty mandibular third molars without caries were randomly divided into two groups; one was polished with silicon carbide sandpaper; the other was polished with silicon carbide sandpaper followed by ultrasonic treatment. Scanning electron microscope (SEM) was used to observe surface of the dentin. Treated teeth were bonded with two universal resin adhesives, Clearfil Universal Bond (pH=2.3) and All-Bond Universal (pH=3.1), and the penetration of the bonding interface was observed with a confocal laser scanning microscope (CLSM) after Rhodamine B staining. Finally, the micro tensile bond strength test was conducted to test the adhesion. Results: The SEM showed that after polishing with silicon carbide sandpaper, the smear layer of the dentin surface was scratched, and dentin tubules were almost completely blocked, with no obvious dentin tubules exposed. After ultrasonic treatment, the scratches were reduced, and a large number of dentin tubules were exposed. CLSM showed that both adhesives could penetrate the dentin along the dentin tubules more deeply after ultrasound treatment. Micro tensile bond strength tests showed that ultrasonic treatment could enhance the bonding strength of two universal resin adhesives. However, there was no statistical difference in bonding strength between these two universal resin adhesives under the same treatment. . Conclusion Ultrasound can partially remove the smear layer on dentin's surface, expose dentin tubules, and increase universal resin adhesives' penetration depth and bonding strength under self-etching mode
