Comparison of rCBF SPECT imaging and clinical visual function of 12 cases with complete homonymous hemianopia (CHH) were taken before and after a course of oriented dynamic color photic stimulation (ODCPS ). It was suggested that ODCPS in patients with CHH was an effective met hod for increasing visual field and improving visual function. Cerebral metabolic patterns of increasing rCBF reflected the mechanism of ODCPS effecting the patients with CHH. The rgtinal- midbrain-occipital visual path way may play an important role in mediating the increase of visual field and restoration of visual function.

Aim To investigate the change in neuropeptide Y(NPY) Y1 receptor level in infarcted myocardium tissues of (MI) rats. Method MI was induced by ligating the left descending anterior coronary artery (LAD) in the heart of rats. The techniques of reverse transcription polymerase chain reaction (RT-PCR) were used to identify the exist of NPY Y1 receptor mRNA in myocardial tissues. The technique of semi-quantitative PCR wa s used to observe the change of NPY Y1 receptor mRNA level. Results NPY Y1 receptor mRNA distributed in the heart tissues of rat. Compared with sham operated rats ,the NPY Y1 receptor mRNA level both in infarction area and non-infarction area was increased significantly after MI fo r 1d and 3d. The NPY Y1 receptor mRNA level in the heart tissues of sham-op erated rats was also significantly increased compared with that in control rats . Conclusion These results suggest that MI may result in increase NPY Y1 receptor level in the heart tissues of rats. Stre ss stimulation such as surgery may also increase the NPY Y1 receptor level in the heart.

OBJECTIVETo explore the clinical effect of the lobulated medial sural artery perforator flap in repairing soft tissue defect in hand or foot.
METHODSSince March 2012 to September 2014, 6 cases with soft tissue defects in hands or feet were treated by lobulated medial sural artery flaps pedicled with 1st musculo-cutaneous perforator and 2st musculo-cutaneous perforator of the medial sural artery. The size of the flaps ranged from 4.5 cm x 10.0 cm to 6.0 cm x 17.0 cm.
RESULTS5 cases of lobulated flap survived smoothly, only 1 lobulated flap had venous articulo, but this flap also survived after the articulo was removed by vascular exploration. All flaps had desirable appearance and sensation and the two-point discrimination was 6 mm in mean with 4 to 12 months follow-up (average, 7 months). Linear scar was left in donor sites in 3 cases and skin scar in 3 cases. There was no malfunction in donor sites.
CONCLUSIONSLobulated medial sural artery perforator flap is feasible and ideal method for the treatment of soft tissue defect in hand or foot with satisfactory effect.

OBJECTIVETo discuss the intervention effect of ligustrazine on ox-LDL-induced foam cells from the perspective of reverse cholesterol transport.
METHODRAW264.7 cultured in vitro was induced with 20 mg x L(-1) ox-LDL to establish the foam cell model, and intervened with ligustrazine. The lipid accumulation in cells was observed by the oil red O dyeing. The changes in total cholesterol and cholesterol ester in the cells were detected with the colorimetric method. The fluorescent quantitative PCR and Western blot were used to detect the mRNA expressions of PPARgamma, LXRalpha and ABCA1.
RESULTLigustrazine could reduce total cholesterol and cholesterol ester in foam cells, inhibit the lipid accumulation, and increase the mRNA and protein expressions of PPARgamma, LXRalpha and ABCA1.
CONCLUSIONLigustrazine can promote the reverse cholesterol transport by increasing the gene expressions of PPARgamma, LXRalpha and ABCA1.

OBJECTIVETo assess the morphologic changes in traumatic cerebral infarction and to discuss its mechanism.
METHODSSpecimens from seventeen cases of cerebral infarction were selected from 81 patients with severe brain injury, and subject to routine gross and histological examinations.
RESULTS(1) The cerebral infarction in all cases was hemorrhagic in nature with a wedged or irregular shape upon gross inspection. The lesions were found in occipital gyrus (8 cases), occipital lobes (3 cases), basal nuclei (3 cases), cingulate gyrus (2 cases), and lateral occipitotemporal gyrus (1 case). Histologically, the lesions were located at the junction between the cortex and medulla, showing congestion, edema, hemorrhage, necrotic nerve tissue and blood vessels. In severe cases, the lesion extended into the entire cortex and subarachnoid spaces. (2) Swelling of the brain and cerebral hernia were found in all cases, 8 of which demonstrated that the posterior cerebral artery was compressed and stenotic within the space between the crus cerebri and uncus.
CONCLUSIONBrain tissue necrosis in traumatic cerebral infarction is the result of brain swelling and cerebral hernia formation, following congestion, bleeding and ischemia due to vasculature compression.

T cell immune receptor with Ig and ITIM domains (TIGIT), a promising new target in cancer immunotherapy, plays a critical role in limiting adaptive and innate immunity against tumors. The extracellular domain of human TIGIT was used to immune BALB/c mice, and a new anti-human TIGIT chimeric antibody (c7D3) was developed. The mice in this study were used in accordance with the international guidelines for the care and use of laboratory animals, and the animal study was approved by the Institutional Animal Ethics Committee of AbMax Biotechnology. The biological activity of c7D3 was studied. The results showed that c7D3 exhibited high affinity for TIGIT and effectively inhibited the interaction between TIGIT and its ligands. Cell-based assays indicated that c7D3 induced strong luciferase signaling in TIGIT/CD155 signaling reporter assay and enhanced cytokine secretion in a T cell stimulation assay. The data showed that c7D3 has high binding affinity and excellent blocking bioactivity, supporting the further advancement for therapeutic application.

Objective To summarize the characteristics of acupoints selection in acupuncture-moxibustion treatment of primary dysmenorrhea (PD) based on data mining. Method Clinical literatures published in the recent 10 years related to acupuncture-moxibustion treatment of PD were collected to establish a prescription database by using Excel. The descriptive analysis, association rules analysis and clustering analysis were conducted by Python and Clementine12.0. Result A total of 74 acupoints were involved with a total frequency of 1072. The leading three meridians were Spleen Meridian (325 times), Conception Vessel (260 times) and Bladder Meridian (158 times); the leading acupoints were Sanyinjiao (SP6, 174 times), Guanyuan (CV4, 111 times), Diji (SP8, 79 times), Ciliao (BL32, 73 times) and Qihai (CV6, 67 times). The utilization of the specific acupoints accounted for 66.22% (49/74). The crossing acupoints were predominant (393 times), especially Sanyinjiao, Guanyuan and Zhongji (CV3), followed by the five-Shu points (195 times), Front-Mu points (195 times) and Yuan-Primary points (99 times). The association rules analysis showed that Guanyuan and Sanyinjiao had the most significant correlation. The clustering analysis figured out 8 core clustering groups. Conclusion The characteristics of acupoints selection revealed in this study provide ideas and references for acupuncture-moxibustion treatment of PD in clinic.
