?AlM: To observe the effect of Qingguang'an on elastic fiber, MMP-7, TlMP-1 in scarring area of filtration canal after glaucoma surgery through the four Qingguang'an effective groups and Qingguang'an granules, to discuss and compare their mechanism of action on scarring area of filtration canal.?METHODS:Four effective components of Qingguang'an were used in groups D, E, F, G and H after glaucoma surgery, compared with group A ( blank ) , group B (model) and group C ( MMC) to observe the effect of elastic fiber, MMP-7, TlMP-1 in scarring filtration canal.?RESULTS:Compared with the preoperative basic lOP and 2d , 1, 2, 4wk postoperative lOP of groups C, E and H, the lOP of three group rose up slower than other groups, and kept the lowest data at 28d. There was significant difference compared with the rest of A, B, D, F, G groups (P<0. 05). The area and density of elastic fiber in surgery group were significantly different with that of black control group ( P<0. 05 ), but there were no statistical differences between groups C and H, groups C and F, groups H and E (P>0. 05). The difference was statistically significant among other groups (P<0. 01).?CONCLUSlON:The scarring area of filtration canal after glaucoma surgery is the major reason which lead to the failure of surgery. Qingguang'an effective group 2, Qingguang'an granules and MMC could reduced the scar tissue by restrained the elastic fiber, TlMP - 1 and increased the MMP-7. By observing the experimental results that both Qingguang'an effective group 2 and Qingguang'an granules could restrained the scarring area of filtration canal, the effects were unbiased, Qingguang'an granules group is better than effective group 2.

The event-related potential (ERP) is considered as one of the most effective methods to study and analyze objectively human mental activity based on nerve electrophysiology. At present, ERP is not only used in the study of lie detection, but also in the clinical medicine for the cognitive assessment on patients with cerebrovascular disease, dementia or traumatic brain injury and auxiliary diagnosis of mental illness. With the further development of ERP detection technology, it would have a wider application prospect in the field of forensic medicine.

BACKGROUND AND OBJECTIVEAs chemotherapy is generally used in the clinical treatment of cancer, the problem of multidrug resistance (MDR) of tumors against the chemotherapeutic agents becomes more and more serious. It has been the major cause for the failure of the chemotherapy. We detected the expressions of beta-catenin and tumor drug resistance related proteins, MRP2, P-gp, and Bcl-2, in esophageal squamous cell carcinoma (ESCC) to explore their function and correlation in the occurrence and development of MDR in ESCC.
METHODSWe used the tissue microarray technique, immunohistochemistry, and image analysis methods to detect the expressions of MRP2, P-gp, beta-catenin, and Bcl-2 proteins and analyze their relationships with clinical data in a ESCC tissue microarray consisting of 582 specimens of ESCC, 294 specimens of normal mucosa, 92 specimens of basal cell hyperplasia, and 87 specimens of dysplasia adjacent to cancer tissue.
RESULTSThe integral optical density (IOD) of MRP2 and Bcl-2, which was 195.7 +/- 175.9 x 10(3)) and 90.5 +/- 112.5 x 10(3)), respectively, was significantly higher in ESCC than in normal mucosa, which was 104.8 +/- 86.1 x103) and 25.2 +/- 46.6 x 10(3)), respectively (P < 0.01). The IOD of P-gp and beta-catenin, which was 57.7 +/- 75.5 x 10(3)) and 32.0 +/- 47.0 x 10(3)) respectively, was significantly lower in ESCC than in normal mucosa, which was 114.8 +/- 106.6 x 10(3)) and 46.1 +/- 35.7 x 10(3)), respectively (P < 0.01). According to the following order, well differentiated moderately differentiated poorly differentiated, the IOD of MRP2 increased in ESCC (P < 0.01). The IOD of beta-catenin was higher in poorly differentiated ESCC than in well or moderately differentiated ESCC (P < 0.01). The IOD of Bcl-2 was lower in well differentiated ESCC than in poorly and moderately differentiated ESCC (P < 0.01). The IOD of beta-catenin and Bcl-2 was higher in the ESCC of specimens with infiltration depths that were in membrane mucosa than those in the muscular layer or serous coat (P < 0.01). The IOD of Bcl-2 was significantly higher in cases with lymph node metastasis than in cases without (P < 0.01). Positive correlations which were respectively between the expressions of P-gp and MRP2, the expressions of P-gp and Bcl-2 were found (r = 0.288 and r = 0.253, respectively, P < 0.01).
CONCLUSIONSMRP2, P-gp, and Bcl-2 may be taken as prognostic factors for MDR of ESCC. beta-catenin may play an important role in carcinogenesis and progression of ESCC.

OBJECTIVETo observe central immediate effect of acupuncture at Yanglingquan (GB 34) on passive movement of cerebral infarction paitents with hemiplegia by functional magnetic resonance imaging (fMRI) and provide reference for clinical treatment.
METHODSWith 1. 5 T MRI scanner, six cases of right cerebral infarction paitents with left hemiplegia in recovery stage were scanned during passive fingers movement before and after acupuncture at Yanglingquan (GB 34), which was controlled with sham-acupoint acupuncture to observe immediate activated part of the corresponding brain.
RESULTSThe activated areas of the passive movement in all the patients were mainly motor sensory cortex on the right side. Compared with sham-acupoint, in the left anterior insula, in ferior frontal gyrus, central gyrus, fusiform gyrus, cerebellum, acupuncture at Yanglingquan (GB 34) has better central effect. These areas were involved with several brain networks.
CONCLUSIONThe acupuncture at Yan glingquan (GB 34) could promote recover of helmiplegia by regulating motor-related network.

OBJECTIVEThis study was aimed at evaluating and comparing the quality of life in patients who underwent laparoscopic and open cholecystectomy for chronic cholecystolithiasis.
METHODSThe study included 25 patients with laparoscopic cholecystectomy (LC group) and 26 with open cholecystectomy (OC group). The quality of life was measured with the Gastrointestinal Quality of Life Index (GLQI) preoperatively, thereafter regularly at 2, 5, 10 and 16 weeks after the operation.
RESULTSThe mean preoperative overall GLQI scores were 112.5 and 110.3 in LC and OC group respectively (P>0.05). In the LC group, the mean overall GLQI score reduced slightly to 110.0 two weeks after the operation (P>0.05). The LC group showed significant improvement in overall score and in the aspects of symptomatology, emotional and physiological status from 5 to 16 weeks postoperatively. In the OC group, the GLQI score reduced to 102.0 two weeks after surgery (P<0.05). Significant reductions were shown in the aspects of symptomatology, physiological and social status. The GLQI scores returned to the preoperative level of 115.6 ten weeks after the operation (P>0.05). The patients experienced significant improvements of GLQI sixteen weeks after OC operation (P<0.01~0.05). Within the 10 postoperative weeks, the LC group had significantly higher GLQI scores than the OC group (P<0.05).
CONCLUSIONSLC can improve the quality of life postoperatively better and more rapidly than OC. The assessment of quality of life assessment is a valid method for measuring the effects of surgical treatment.

OBJECTIVETo determine microdeletion loci and the characteristic of Y chromosome azoospermia factor(AZF) associated with Chinese idiopathic azoospermia or severe oligozoospermia and hence to provide a theoretic basis for gene diagnosis of AZF microdeletion in Chinese infertility men.
METHODSThe subjects of this study included 134 cases of azoospermia and 118 severe oligozoospermia, and 210 healthy male controls. With multiplex PCR technique, an analysis of 15 sequence tag sites(STS) in AZFa, AZFb and AZFc microdeletion was performed.
RESULTSNo microdeletion was detected in controls whereas 13 STS loci microdeletions existed in cases, including sY84 and sY86 in AZFa; sY121, sY123, sY124, sY127, sY134 and sy133 in AZFb; sY152, sY242, sY254, sY255 and sY157 in AZFc. Five azoospermia patients were involved in AZFa microdeletions, 7 azoospermia and 3 severe oligozoospermia patients in AZFb, and 14 azoospermia and 18 severe oligozoospermia patients in AZFc. The prevalence rates of microdeletion in AZFa, AZFb and AZFc were 2.0%,4.0% and 12.7% respectively. The microdeletion rate showed statistically significant difference between the cases and controls.
CONCLUSIONThis study revealed an association between the microdeletion of 13 STS loci of AZF region and the idiopathic azoospermia or severe oligozoospermia in Chinese. There is no evidence to identify the genetic polymorphism of the above STS loci. The frequency and distribution characteristic of AZF microdeletion are similar to those of Caucasians. As candidate loci the 13 STS are useful in clinical gene diagnosis for the detection of AZF microdeletion in Chinese idiopathic azoospermia and severe oligozoospermia.

Infant hemangioma, the most common benign tumor in children, is characterized by rapid proliferation, followed by slower spontaneous involution. However, some patients with facial segmental hemangioma are associated with PHACE syndrome. PHACE syndrome is characterized by vascular nerve and vascular cutaneous lesions of multiple systemic systems, often resulting in structural and functional impairments. Recent studies have demonstrated that the possible pathogeneses of PHACE syndrome mainly include hypoxia, abnormality of mesodermal vascular endothelial cells, genetic abnormality, and abnormality of interstitial mesenchymal stem cells. The current medications for hemangioma with PHACE syndrome include beta blockers, glucocorticoids, and mTOR inhibitors. This review article mainly describes the pathogenesis, diagnoses and treatments of PHACE syndrome, in order to provide directions for diagnosis and treatment of this disorder.
