1.Research on collaborative innovation in traditional Chinese medicine of China based on patent cooperation network.
China Journal of Chinese Materia Medica 2015;40(6):1212-1218
In the situation of global completion, collaborative innovation is becoming increasingly important because its advantage in risk avoiding and innovation efficiency. In order to explore the model of collaborative innovation and its evolution in traditional Chinese medicine of China, the cooperation in traditional Chinese medicine patents of China from 1985 to 2013 has been analyzed by using the method of scientometrics and social network analysis. It is proved that, though the number of grated cooperative patents has increased sharply during the last thirty years, the degree of cooperation innovation in traditional Chinese medicine of China is still not high. Moreover, in spite of the individual subject' s leading role in the past domestic collaborative innovation in traditional Chinese medicine of China, the institutions have been more and more powerful and achieved great improvement. At last, core institutions, represented by universities have played an important role in the collaborative innovation of domestic institutions, because they are key links between many institutions and promote the transferring and diffusion of knowledge.

Objective To provide anatomical evidence for a safe osteotomy line and direction in periacetabular osteotomy.Methods The pelvic CT images of 18 adults were obtained.With the help of Mimics software,three-dimensional CT reconstruction was performed,and periacetabular osteotomy was simulated.The length of osteotomy lines on the ilium,ischium and iliac columna posterior was measured,and the relationship between osteotomy lines and anatomic landmarks was explored. Results The length of osteotomy lines on the ilium,ischium and iliac columna posterior was(50.96?7.09) mm,(36.46?5.92)mm and(55.28?6.42) mm,respectively.The angles between the osteotomy line on the ilium and that on the iliac columna posterior,between the osteotomy line on the ischium and that on the iliac columna posterior,and between the osteotomy line on the iliac columna posterior and quadrilateral surface were 120.21??5.96?,115.49??6.46? and 60.31??4.96?,respectively.And the real periacetabular osteotomy has been performed on the pelvic specimens for verification.The vertical distances between the ending point of osteotomy line on the ilium and iliopectineal line,between osteotomy line on the ischium and iliopectineal line,and between the osteotomy line on the iliac columna posterior and greater sciatic notch were(11.98?5.26) mm,(45.08?8.59) mm and(18.52?6.49) mm,respectively. Conclusion The length and angles of osteotomy lines in periacetabular osteotomy can be well measured by three-dimensional reconstruction,and the relationship between the osteotomy lines and anatomic landmarks can also be well displayed,which provides anatomical data for the clinical application of periacetabular osteotomy.

Objective To explore the patterns of cognitive performance across different clinical states of bipolar disorder(BPD).Methods 8 neuropsychological tests (17 items) which examine attention,verbal learning and memory,visual memory and executive function were given to 30 depressed BPD ,30 manic BPD ,30 remitted BPD and 34 normal controls.The difference of cognitive functions between the four groups were compared using multivariate analysis of variance (MANOVA).Results Acute patients with BPD showed dysfunction in almost all neuropsychological tests compared with controls [ the score of WCST categories of manic BPD,depressed BPD,remired BPD and normal controls was( 1.58 ±0.90),( 1.89± 1.56),(2.44 ± 1.42),(4.90 ± 1.73 ) respective-ly.The score of immediately logical memory was (10.68±3.92),(10.00±3.80) ,(12.11±3.72),(15.80±4.21) respectively] (P<0.05,P<0.01).The remitted patients showed deficits in attention,verbal learning and memory,executive function tasks in relation to controls (P<0.05,P<0.01).Conclusion There were general cognitive deficits in acute patients with BPD,and some of these deficits may persists in remission state.

Integrating physiological parameters measurement into mobile devices is a development tendency of mobile healthcare. Measurement methods for skin moisture and body fat content are studied in this paper. Electrodes are designed for easy integration into mobile devices, and can be embedded in the cover of the mobile phone. Experiments were conducted to obtain a fast and easy measurement method. The results of evaluation show that the measurement system can achieve the same accuracy as commercial products (with correlation above 0.9 and root mean squared error below 4%) in skin moisture and body fat content measurement. Measurement of local-area body fat content showed a nearly linear positive correlation between local-area body fat content and local-area body impedance.

Objective To understand the distribution of the genotypes of ?-lactamases in Chryseobacterium/Flavobacterium spp.Methods Minimum inhibitory concentrations (MICs) of 43 Chryseobacterium meningosepticum strains,22 Chryseobacterium indologenes strains and 10 Chryseobacterium gleum strains against 15 antibiotics were determined by agar dilution method.3-D test and modified 3-D test were used to identify carbapenamase.2-mercaptopropionic acid inhibitory test was used to confirm metallo-?-lactamases (MBL).Genes of ?-lactamases were amplified with 6 pairs of primers special for Chryseobacterium/Flavobacterium spp.and the amplified genes were sequenced.Results MIC_(50) and MIC_(90) of quinolones were lower comparing to other antibiotics.MICs of C.gleum against 15 antibiotics were lower than other Chryseobacterium/Flavobacterium spp.Among 43 C.meningosepticum strains,26 strains (60.5%) produce MBL,but all strains (100%) produced extended-spectrum ?-lactamases (ESBLs);12 C.indologenes strains (68.8%) produced MBL;6 (60%) C.gleum strains had MBL.Genotypes of MBL in C.meningosepticum strains were Bla-B 1,2,3,5 and 11,and Bla-GOB 2,4,6 and 8,respectively.Only one genotype,namely CME-1,was identified for ESBL in C.meningosepticum.The genotype of MBL in 3 C.indolgenes strains was IND-1,and the 6 C.gleum strains contained CGB genotype.Meanwhile,there were 8 C.indolgenes strains and 3 C.gleum strains were confirmed to produce ?-lactamase,but their genotypes were unable to be detected using the current primers,implying that there were possible novel genotypes.Conclusions Investigation of genotypes distribution of ?-lactamase in Chryseobacterium/ Flavobacterium spp.can provide theoretical evidences and rational in the selection of antibiotics,control of noscomical infection and development of novel antibiotics.

ObjectiveTo avoid the complications such as scar,alopecie,scalp numbness,hematoma etc,resulted from the conventional coronal incision rhytidectomy,and to explore and solve the issues about endoscopic frontal and temporal rhytidectomy.MethodsThrough 3-5 short incisions in hairline,we dissected under frontal periosteum or gales aponeurotica and in superficial layer of deep temporal fascia.The frontal and temporal cavitites were feedthrough at temporal crest.The corrugator supercilii muscle,superciliary depressor muscle,frontal muscle and orbicularis oculi were treated.Sufficient dissection was done under the periosteum of os orbitale.ResultsThis method had been applied in 186 patients with forehead lift.After operation,transient paralysis of facial nerve frontal branch were found in 3 patients.The depression of glabellum and lateral canthus were found in 5 patients.The depressions were corrected by autologous fat injection. Other 178 patients' results were satisfactory.ConclusionsEndoscopic frontal and temporal rhytidectomy has some advantages,such as minute invasion,less hemorrhage,few complications,and stable operation result,etc.Compared to the conventional coronal incision rhytidectomy,this method will be used more widely.
