【Objective】 To establish a routine screening method for unexpected antibodies of blood donors, analyze the results of centralized screening for unexpected antibody of blood donors in the blood center, and compare the cost of centralized and decentralized screening modes. 【Methods】 A total of 35 591 blood donors were screened for unexpected antibodies from March 31, 2021 to July 31, 2021, using microcolumn gel method. Unexpected antibody screening reactive samples were further confirmed by the Transfusion Research Institute of Shenzhen Blood Center, and the demographic characteristics were further determined through the analysis of unexpected antibody positive population. The direct cost and indirect cost of centralized and decentralized unexpected antibody screening mode were compared. 【Results】 Forty unexpected antibody positive samples were confirmed in Shenzhen, with the positive rate at 0.11%(40/35 591), among which MNS, Rh and Lewis system accounted for 35% (14/40), 32.5% (13/40) and 17.5% (7/40), respectively. Males and females accounted for 45% (18/40) and 55% (22/40), respectively (P<0.01). No significant difference was noticed by age and repeated-donor or not (P>0.05). Unexpected antibody screening in a centralized way saved about 1.16 million yuan per year. 【Conclusion】 It is necessary to carry out unexpected antibody screening for all blood donors, and centralized screening is more economical than decentralized screening.

Objective:To investigate the effects of posterior condylar offset (PCO) change on functional recovery after high-flexion posterior-stabilized total knee arthroplasty (TKA).Methods:From December 2018 to May 2019, a total of 76 patients (7 males and 69 females) who underwent primary TKA were included. The age of patients was 67.78±5.13 years (56-75 years). Preoperative and postoperative radiological PCO were measured by lateral knee X-ray. The true preoperative PCO was defined as the sum of radiological PCO and the thickness of posterior condylar cartilage. According to the changing of PCO (ture preoperative PCO - postoperative PCO), the subjects were divided into four groups, namely 28 cases in ≤-3 mm group, 23 cases in -3 mm- group, 15 cases in 0 mm- group and 10 cases in ≥3 mm group. The parameters, including age, body mass index, range of motion (ROM), Knee Society Scores (KSS) and visual analogue score (VAS) before the operation, were not significantly different among four groups. ROM, KSS, VAS at 2 weeks, 1 month, 3 months, 6 months after the operation were compared among the four groups.Results:There were good inter-observer reliabilities regarding the parameters measured in this study ( ICC>0.75). The KSS, ROM, VAS of all the subjects after operation were significantly better than those before the operation ( F=318.768, 64.983, 361.749; P=0.000). In all groups, the recovery of KSS and VAS last to 6 months after the operation. The ROM trended to be stable at the 3 months after the operation. At 6 months after operation, ROM, KSS and VAS of ≤-3 mm group was 116.07°±9.66°, 156.25±21.49, and 1.18±0.94, respectively. These parameters of -3 mm- group was 119.57°±7.52°, 162.17±17.09, and 1.26±0.86. However, these parameters of 0 mm- group was 126.07°±5.25°, 161.86±8.86, 1.00±0.55, respectively. These of ≥3 mm group was 118.00°±4.21°, 156.60±16.98 and 1.30±0.95. The KSS, KSS anatomy score, KSS function score and VAS were not significantly different at any follow-up point among four groups. The ROM of 0 mm- group at 1 month, 3 months and 6 months after operation (118.57°±13.07°, 25.00°±6.20°, 126.07°±5.25°) was significantly different from other three groups ( F=4.966, P=0.003; F=4.179, P=0.006; F=5.262, P=0.003), while 0 mm- group's ROM were greater than other three groups ( P<0.05). Conclusion:Increasing within 3 mm of PCO was related to larger postoperative ROM in high-flexion posterior-stabilized TKA. However, change of PCO had no influence on the outcomes of KSS recovery and pain relief.

Through analysis and summary of the biological characteristics of various biomarkers, to explore the reliability of different markers for early diagnosis of osteoarthritis. Cartilage oligomeric matrix protein, N-terminal crosslinked telopeptide of type Ⅰ collagen and C-terminal crosslinked telopeptide of type Ⅱ collagen are the possible effective markers in osteoarthritis early diagnosis. Hyaluronic acid and C-terminal crosslinked telopeptide of type I collagen are more suitable for evaluating the ollurrence and derelopment of osteoarthritis. The efficacy of miRNA and lncRNA in osteoarthritis diagnosis and evaluation remains to be proved. Each marker may has two or more biological effect, this paper will focus on finding out an accurate and stable marker with the analysis and summary of present bio-markers.

To study the protective effect of Xingnaojing Injection on early global brain ischemia-induced deep coma in rats.
 Methods: The deep coma model was induced by global brain ischemia by using four-vessel occlusion method in male SD rats. According to the body weight, the rats were randomly divided into 8 groups: a model control group, three different dose of Xingnaojing Injection (1.8, 3.6 and 5.4 mL.kg-1) groups, a Xingnaojing Injection (3.6 mL.kg-1) plus PI3K inhibitor group, a naloxone injection (0.04 mL.kg-1) group and a naloxone injection (0.04 mL.kg-1) plus Xingnaojing Injection (3.6 mL.kg-1) group (n=8 per group). In addition, eight animals served as the sham group were performed same operation with the model group excepting no blockage of the blood vessels. After the operation, three different doses of Xingnaojing Injection and/or naloxone injection were given intravenously once a day for three days. Ten μL PI3K inhibitor (LY294002, 10 mmol/L) was injected via anterior cerebral ventricle at once after global brain ischemia. The awakening time after the first drug treatment, the grasping power and the autonomous activity within 10 min after the last drug treatment were recorded. The levels of both dopamine (DA) and glutamate (Glu) in cerebrospinal fluid were detected by ELISA. The pathological changes were observed in brain tissue slices with HE staining and the protein levels of Akt/p-Akt and cAMP-response element binding protein (CREB)/p-CREB in hippocampus were detected by Western blotting.
 Results: Comparing with the model group, single administration of Xingnaojing Injection could significantly shorten the waking time (P<0.05) and continuous administration of Xingnaojing Injection for 3 d could increase grasping power, distance, frequency and duration of autonomous activities (P<0.05 or P<0.01) in the deep coma rat. Also, Xingnaojing Injection could inhibit these increases in neurotransmitters DA and Glu contents (P<0.05 or P<0.01), and improve pathological changes of hippocampal tissue. Xingnaojing Injection significantly induced protein phosphorylation of both Akt and CREB (P<0.05 or P<0.01); this effect was inhibited by PI3K inhibitor (P<0.05 or P<0.01). Moreover, the protective effects of naloxone on awakening time, grasping power, the autonomous activity and hippocampus damage in global brain ischemia-induced deep coma could be enhanced by joint use of Xingnaojing Injection (P<0.05 or P<0.01).
 Conclusion: Xingnaojing Injection could significantly improve deep coma induced by global brain ischemia in rat, which is related to inducing PI3K/Akt-dependent protein phosphorylation of CREB, and reducing hippocampal damage. The protective effect of Xingnaojing Injection is synergistically enhanced by naloxone.
