In recent years, more and more biological materials are used in bone defect repair. The ideal materials should not only have good biocompatibility, but also have the right space structure, surface morphology and the physical and chemical properties, to adapt the growth of osteoblasts. Calcium phosphate cement was used more widely among biological materials in bone defect repair with its good biocompatibility, degradability, osteoconductivity, injection, plasticity and other advantages. This paper introduced the experimental research and progress of the calcium phosphate cement application in bone defect repair.

Rhoptry proteins are the major virulence factors of Toxoplasma gondii. They locate in different parts of the host cells and can affect the membrane cytoskeleton structure and active factors of the host cells so as to block the cell intrinsic de-fense mechanisms of the host and let T. gondii invade parasitize and proliferate in the host successfully. The function and ac-tion mode of rhoptry proteins reflect the pathogenic mechanism of T. gondii which holds great significance to looking for toxo-plasmosis drug targets and developing molecule vaccines. This paper reviews the research progess of the interaction between rhoptry proteins of T. gondii and host cells.

Toxoplasma gondii rhoptry proteins (ROPs) include dozens of proteins secreted by tachyzoites ,these ROPs are known to be critical for several processes such as invasion ,parasitophorous vacuole establishment ,proliferation ,egress and getting out of host immune protection .ROPs belong to the protein kinase family and have classic kinase domain ,however ,most of the members are designated as pseudokinases due to the lack of critical catalytic residues that are normally required for phos-phorylation of host signal molecules .Recent studies indicated that pseudokinases also have important functions ,such as regula-ting kinase activity by allosteric and promoting the interactions between proteins as scaffolds .In this paper ,we summarize the pseudokinases structural characteristics and some pseudokinases functions ,for the study of toxop lasma gondii and host interac-tion mechanisms ,molecular vaccines screening and drugs design .

Objective To develop a rapid molecular biological method for detection of the asymptomatic infection of Leish?mania. Methods Two pairs of primers named RV1?RV2 and K13A?K13B were selected to be the fast diagnosis primers since they were designed according to the conserved region of Leishmania kinetoplast DNA(kDNA)minicircles. The PCR amplifica?tion products of Leishmania donovani promastigote from Shandong Province were sequenced to compare their conservatism. The method was applied to detect 105 venous blood samples from healthy home canine and 7 venous blood samples from home canine suffered from Kala?azar in Heishui County of Sichuan Province,and 75 venous blood samples from susceptible population(no leishmaniasis symptoms)and 7 venous blood samples from patients in Xinjiang Kashi area in order to verify the feasibility and accuracy of the method. Results The size of PCR products was consistent with the expected fragments with high conservative among Leishmania species. The positive rates of 105 home canine samples and 75 susceptible population samples were 37.14%(39/105)and 82.67%(62/75)rspectively,and the positive rates of home canine suffered from Kala?azar and patients were all 100%(7/7). Conclusion This rapid diagnosis method is suitable for detection of asymptomatic infection of Leishmania in Kala?azar endemic areas of China with high sensitive and specific,thus it has bright perspective to be used.

Objective To observe the therapeutic efficacy of acupuncture at the interiorly-exteriorly related meridians plus rehabilitation training in treating post-stroke shoulder-hand syndrome. Methods Sixty eligible patients with post-stroke shoulder-hand syndrome were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by acupuncture at the interiorly-exteriorly related meridians plus rehabilitation training, while the control group was by rehabilitation training alone. After 2 treatment courses, the Fugl-Meyer Assessment (FMA), visual analogue scale (VAS) and edema score were observed and compared. Results The FMA, VAS, and edema scores were significantly changed in both groups after intervention (P＜0.01). There were significant differences in comparing the FMA, VAS, and edema scores between the two groups after intervention (P＜0.05). The total effective rate was 83.3%in the treatment group versus 76.7%in the control group, and the difference was statistically significant (P＜0.05). Conclusion Acupuncture at the interiorly-exteriorly related meridians plus rehabilitation is an effective method in treating post-stroke shoulder-hand syndrome.

Objective To investigate the feasibility and effect of intentional occlusion of the left subclavian artery (LSA) in endovascular aortic repair EVAR of thoracic aortic disease.Methods The cases,who needed occlusion of the LSA in EVAR of thoracic aortic disease,were examined cerebral circulation,carotid artery,vertebral basilar artery and circle of Willis.If the vertebral artery had a good blood pathway,and carotid artery and circle of Willis had no stenotic,we occluded the LSA directly in EVAR,and observed the brain and upper limb ischemia complications postoperation.Results Among 40 cases who were occluded the LSA directly in EVAR,28 cases were successful with no neurological complications and left upper limb ischemia symptoms postoperation,12 patients with mild symptoms of subclavian steal syndrome and neurdogical complications,but none required and secondary surgical intervention.Conclusions Prior to intentional LSA occlusion,attention must be paid to potential supraaortic variants and pathologies.Only in this way,it was safe and effective to occlude the LSA in EVAR of thoracic aortic disease.

Objectives To summarize the clinical characteristics of imported falciparum malaria patients and the treatment so as to provide the evidences for improving the diagnosis and treatment of the disease. Methods A total of 138 imported falci?parum malaria patients who received the treatment in Shandong Institute of Parasitic Diseases from January 2007 to February 2013 were adopted as the observation subjects and their clinical data were collected and analyzed. Results All the 138 pa?tients were back from African countries. The main manifestations were fever headache asthenia and hepatosplenomegaly and most of them were with decreased RBC PLT levels and increased LDH levels and 36.96%of them were misdiagnosed as respiratory diseases nephritis hepatitis and so on. Through antimalarial treatment of artemether or artesunate or dihydroartemis?inin and primaquine or dihydroartemisinin and piperaquine and symptomatic treatment the short?term and long?term cure rates were 98.55%and 94.93%respectively with 1 case unrecovered and 1 died. Conclusions Artemisinins are still the most effective antimalarial drugs for falciparum malaria. However some patients recrudesce as the Plasmodium in their body is resis?tant or insensitive to these drugs. We should pay more attention to the antimalarial and symptomatic treatments in the early stage of severe malaria so as to improve the cure rate.

ObjectiveTo evaluate the clinical value of prenatal ultrasonography combined with maternal serology screening for chromosomal abnormality in 15 to 20+6 gestational weeks.MethodsSix hundred and twenty-eight pregnant women (628 fetuses) in 15 to 20+6 gestational weeks were selected to undergo prenatal ultrasonography, who were in critical risk of trisomy 21 or trisomy 18 by maternal serology screening. Transabdominal ultrasonography were performed and fetal nasal bone and nuchal fold were detected. Those who had nasal bone hypoplasia, thickened nuchal fold (NF>6 mm) and other abnormal fetal soft markers underwent amniocentesis for karyotyping analysis. ResultsThere were 6 cases of nasal bone hypoplasia (0.96%, 6/628), including one case of thickened nuchal fold, two cases of echogenic bowel, two cases of choroid plexus cysts and 1 case of echogenic cardiac focus. All these 6 cases underwent amniocentesis and 2 were trisomy 21 (33.3%, 2/6). The other 4 cases had no significant chromosomal abnormality.ConclusionsPrenatal ultrasonography may improve the detection rate of chromosomal abnormality for those pregnant women who are in critical risk of chromosomal abnormality prompted by serology screening. But invasive procedures are still needed to verify the chromosomal abnormality.
