Objective To investigate the effect of cerebrospinal lfuid replacement combined with vancomycin and dexamethasone intrathecal therapy on biochemical indicators of postoperative intracranial infection, in order to improve the clinical diagnosis and treatment. Methods 70 cases with intracranial infection collected in Third Hospital of Beijing Armed Police Corps from February 2010 to April 2013 were as subject, and randomly divided into two groups. Control group(n=35) were given cerebrospinal lfuid replacement and ceftriaxone intravenously, observation group(n=35) were given cerebrospinal lfuid replacement combined with vancomycin and dexamethasone intrathecal injection. The clinical effects and biochemical indicators were observed after treatment in two groups. Results In control group, the cure rate was 22.86%and total efifciency was 77.14%. In observation group, the cure rate was 37.14% and total efficiency was 91.43%. The differences between two groups were statistically significant (P<0.05). The differences of leukocytes, glucose, protein, intracranial pressure in two groups after treatment were also statistically signiifcant(P<0.05). Conclusion Cerebrospinal lfuid replacement combined with vancomycin and dexamethasone intrathecal injection therapy can increase intracranial infection.

Objective To express the recombinant protein VP1-Z, and investigate whether VLP-Z has the physiological functions like as wild-type VLP. Methods The expression plasmid pET15b-VP1-Z was introduced into competent E. coil BL21 (DF3)/pLys cells by transformation, and the expression of re-combinant protein VP1-Z was induced by incubation of the cells with IPTG. The protein was prepared as pre-viously described for wild-type VLP. The morphous of VLP-Z were observed by electron microscopy, and the physiological functions of VLP-Z were investigated by hemagglutination test and by immunofluorescence. Re-sults The purified VLP-Z composed of VP1-Z possessed hemagglutination activity and yielded a prominent band of 50×10~3 on SDS-PAGE and staining with Coomassie Brilliant Blue. The VLP-Z exhibited virus-like particles structure like as wild-type VLP with a diameter of 45-50 nm, which was slightly bigger than that of wild-type VLP(42-45 nm). In immunofluorescence test, VP1-Z was detected within the cytoplasm and nu-cleus after HeLa cells were inoculated with VLP-Z. Conclusion The physiological functions of recombinat-ed protein VLP-Z were comparable with wild-type VLP.

Objective To construct the vector pET15b-Z-VP1 by inserting the Z fragment into amino-terminal of JCV VP1.Methods The VP1 and Z fragment were amplified by PCR from plasmid pET15b and pEZZ18 respectively,and then they were linked by recombinant PCR.The Z-VP1 fragment was inserted into plasmid pET15b by restriction enzyme BamHⅠ and NcoⅠ.Results The VP1 and Z fragment were obtained by PCR and gel purification.The Z-VP1 fragment,which was linked by recombinant PCR from VP1 and Z fragment,was inserted into plasmid pET15b between BamHⅠ and NcoⅠ sites,and confirmed by enzyme digestion and DNA sequencing.The expression of VP1-Z was confirmed by Western blotting.Conclusion The plasmid pET15b-Z-VP1 has been constructed successfully by inserting Z fragment into amino-terminal of VP1.

Objective To investigate self-management behaviors of kidney transplantation recipients after discharge.Methods A total of 97 kidney transplantation recipients were recruited from a teaching hospital of Peking University From September 2009 to June 2012,and all eligible subjects were then assigned to 3 groups:post-transplantation less than 6 months group (group A),post-transplantation 6-12 months group (group B),and post-transplantation more than 12 months group (group C).The subjects were required to complete self-management scale for renal transplant recipients.ANOVA was used for data analysis.Results There were 32 patients in group A,31 in group B,and 34 in group C.Self-management behavior score of the participants of the three groups was 100.1 ± 7.0,99.0 ± 7.3 and 91.3 ± 5.8,respectively (F =3.53,P =0.03).In terms of diet,group B got the highest score (F =16.41,P =0.00).However,group A showed excellence in physical activities (F =11.50,P =0.00).For three groups,score of drug effect and side effect was 2.00 ±0.00,2.03 ±0.18,and 2.41 ±0.50; score of routine laboratory values was 2.00 ±0.00,2.05 ± 0.16 and 2.82 ±0.39; and score of skin protection was 3.09 ±0.30,3.03 ± 0.91,and 2.85 ±0.36,respectively.Conclusions Post-transplantive self-management behavior of patients who completed the surgery for more than 12 months may not be better than others.Healthcare professionals need to improve patients' self-management through health education.

Background: Radiation pneumonitis is one of the most common complications during radiotherapy of thoracic tumors. It impacts the quality of life of the patients and has life-threatening danger. However, there is a lack of drugs for prevention and treatment of this disease. Objective: To evaluate the efficacy of Liangxue Jiedu Huoxue Decoction, a compound traditional Chinese herbal medicine, in prevention of radiation pneumonitis. Design, setting, participants and interventions: A prospective randomized clinical study was conducted. A total of 100 patients diagnosed with lung cancer from Department of Radiotherapy, Chinese PLA General Hospital, who were planning to receive radiotherapy, were randomly assigned into treatment group and control group, with 50 patients in each group. In the treatment group 3 cases were lost to follow-up and one case was excluded, while in the control group 6 cases were lost to follow-up and 2 cases were excluded. Patients in the treatment group were treated with Liangxue Jiedu Huoxue Decoction in addition to radiotherapy, while patients in the control group were treated with radiotherapy alone. Main outcome measures: The incidence rates of radiation pneumonitis in the two groups were calculated. Acute radiation injury scoring criteria by Radiation Therapy Oncology Group (RTOG), clinical-radiographic-physiologic (CRP) score system, and Karnofsky Performance Status Scale (KPS) were used to evaluate the status of the patients. Results: The incidence rate of radiation pneumonitis was lower in the treatment group than in the control group (13.04% versus 33.33%, P<0.05). According to the RTOG scale, the extent of lung injury was improved in the treatment group as compared with that in the control group (P<0.05). The CRP score in the treatment group was significantly lower than that in the control group (P<0.05). The KPS score in the treatment group was significantly higher than that in the control group (P<0.05). Conclusion: Liangxue Jiedu Huoxue Decoction can decrease the incidence rate of radiation pneumonitis, reduce the extent of the lung injury, alleviate the symptoms of radiation pneumonitis, and improve life quality of the patients.
