Objective To test the reliability and validity of the Chinese version of the John Hopkins Adapted Cognitive Exam ( ACE) in NICU patients. Methods The English ACE was translated and adapted into the Chinese version . Cognitive functions of 40 critically ill patients in NICU were assessed with the Chi?nese version of ACE and MMSE battery.The scores of ACE and MMSE were analyzed to test the content va?lidity,construct validity,concurrent validity,internal consistency,inter?rater reliability and test?retest reliabil?ity.Result The correlation coefficient between each factor and the total score ranged from 0.617 to 0.938, and the content validity was good.The ACE was significantly correlated with MMSE( r=0.822, P<0.05). Five factors were extracted by main principle analysis, the cumulative contribution was 85. 90%, the factor loading of each item was all over 0.5,the scale had good construct validity.There existed a good internal con?sistency ( Cronbach’ α=0.756 ) as well as a good inter?rater reliability ( ICC>0.95) and test?retest reliabil?ity (ICC=0.652?0.979) of the Chinese version of ACE.Conclusions The Chinese version of ACE has been proved to be a reliable and valid screening tool for cognitive impairment in NICU patients.

The Qinbai Qingfei concentrated pellets by traditional Chinese medicine theoryand party and group, the rats were given the drugs group, comparison of pharmacokinetics parameters changes of baicalin , discusses the rationality of Qinbai prescription. The rats were gavaged monarch drug group (Huang Qincu extract, mainly forbaicalin), and official medicine group, adjuvant group, medicine group and Qinbai group (Quan Fangzu) the content of baicalin equal as the monarch drug group, in the 28 h collection in rat plasma at different time point, application of HPLC determination of baicalin glycosides in rat plasmaconcentration time curve, with 3P97 practical pharmacokinetics program to process the data Based on the data analysis, baicalin in rat plasma of Qinbai group Cmax is 4 times as big as monarch druggroup, AUC is 6 times as big as monarch drug group; the content of baicalin in plasma of rats the highest is Qinbai group, the minister drug group, adjuvant group, medicine group of baicalin in rat plasma content of less than the Qinbai group, but was significantly higher than that of monarch drug group; the medicine group is slightly higher than that adjuvant the content of baicalin in plasma of rats. The pharmacokinetic results show that the measured plasma concentration in rats that Qinbai can significantly increase Cmax and AUC of baicalin, other components of qinbai can promoted the baicalin absorption in vivo. It showed that the reasonable of Qinbai compound compatibility. The minister drug can promote the absorption of baicalin in vivo.

Objective To investigate the clinical validity of the Chinese version of John Hopkins Adapted Cognitive Exam (ACE) for in-patients in neurological intensive care unit (NICU). Methods From May, 2014 to June, 2015, 94 inpatients in NICU and 52 healthy persons were assessed with the Chinese version of ACE and Mini-Mental State Examination (MMSE). Results The total score of ACE correlated with the total score of MMSE (r=0.805, P<0.001). There was a significant difference in the total score and the scores of the subtests of both the ACE and MMSE between the patients and the controls (t>2.458, P<0.05). The area under the receiver operating curve was not different between ACE and MMSE (Z=0.707, P=0.480). Conclusion The Chinese version of ACE can be the tool for assessment of cognition for pa-tients in NICU.

OBJECTIVETo investigate the effect of vascular bundle implantation in autogenous bone graft on angiogenesis.

METHODSThirty-six New Zealand white rabbits were evaluated in this study. A portion of bilateral radial bones of a rabbit were removed as free bone grafts, whose periostea were peeled off. In test group, the external maxillary artery bundle was passed through the marrow cavity of the bone. In control group, there was no vascular bundle implantation. Each bone was placed in masseter muscle separately. The rabbits were sacrificed and the specimens were procured at 3 days, 1, 2, 3, 4 and 6 weeks after surgery for histological observation, Chinese ink perfusion and CD34 immunohistochemistry. Microvessel density (MVD) was assessed in order to evaluate angiogenesis of autogenous bone grafts.

RESULTSThe bone grafts were found revascularization in 3 days after surgery in the test group, whereas at 2 weeks in the control group. In 3 days, 1 week, 2 weeks, 3 weeks and 4 weeks after surgery, the MVD of test group was significantly higher than that of control group. In 4 weeks after surgery, angiogenesis of test group reached to peak.

CONCLUSIONVascular bundle implantation improved angiogenesis in non-vascularized autogenous bone graft in this study.

This study is to investigate the protein and mRNA expressions of pro-inflammatory and anti-inflammatory cytokines in U937 foam cells and effects of Ginkgo biloba extract (GbE) on the cytokines. U937 cells were cultured with different concentrations of GbE (0.1, 1, and 10 microg x L(-1)), and stimulated by 100 mg x L(-1) oxidized low density lipoprotein (ox-LDL) for 24 h. The expressions of interleukin-1beta (IL-1beta), tumor necrosis factor-alpha (TNF-alpha) and interleukin-10 (IL-10) in culture solution were detected by enzyme-linked immunosorbant assay (ELISA) and reverse transcriptase polymerase chain reaction (RT-PCR). The results showed that incubated with 100 mg x L(-1) ox-LDL for 24 h, the U937 cells became foam cells, the protein or mRNA expressions of IL-1beta, TNF-alpha, IL-10, and its receptor IL-10R in U937 foam cells were higher markedly than those in normal U937 cells. When the cells were pretreated with GbE (0.1, 1, and 10 microg x L(-1)), the increases of IL-1beta and TNF-alpha in U937 foam cells were remarkably inhibited, but IL-10 expression increased greatly. Especially when cells were pretreated with 10 microg x L(-1) GbE, the protein and mRNA expressions of IL-1beta and TNF-alpha were markedly lower than those in U937 foam cells. The protein expression of IL-10 and mRNA expressions of IL-10 and its receptor IL-10R were markedly higher than those in U937 foam cells. GbE inhibited production of pro-inflammatory cytokines IL-1beta and TNF-alpha, but up-regulated the production of anti-inflammatory cytokine IL-10 and its receptor IL-10R in U937 foam cells, which might be related with its anti-atherosclerotic actions.

OBJECTIVETo construct a clinical database for laparoscopic colorectal surgery in Chinese population using computerized technique.

METHODSA clinical database system was constructed and used in multi-/single-center studies on laparoscopic colorectal surgery.

RESULTSThe data of more than 1200 cases in the Nanfang Hospital during the past year were collected retrospectively. The database was used as the platform for "Southern China Laparoscopic Colorectal Surgery Study Group (SCLCSG)" and was used in the first stage of the clinical research of "Multicenter retrospective study of laparoscopic and open procedure for colorectal cancer" among 11 hospitals in Southern China. In order to test the system, the database was also used in "comparative study on oncologic results of laparoscopic versus open radical resection for rectal carcinoma".

CONCLUSIONSThe evaluation system is reliable and efficient. This system has established a clinical database for laparoscopic colorectal cancer surgery and can be widely applied for the clinical research for colorectal cancer.

Photodynamic therapy (PDT), because of its good targeting, minimal invasion, and safety, is becoming a very active area in cancer prevention and treatment, in which the photosensitizers have proved to be the core element for PDT. We developed a new HPLC method for analyzing porphyrin photosensitizers using Shiseido Capcell PAK C18 (150 mm x 4.6 mm, 5 µm) as the column at 30 °C, methanol-1% aqueous solution of acetic acid as the mobile phase in a flow rate of 1.0 mL · min(-1) in a gradient elution mode, and the detection wavelength at 380 nm. This method, showing good specificity, precision, accuracy and robusty via methodology validations, can be applied to the purity test and assay of porphyrin photosensitizers, and has played a key guide role in the R&D of the new porphyrin photosensitizer--sinoporphyrin sodium.
