The changes of pathophysiology of perihematomal tissue after intracerebral hemor- rhage are extremely complicated.Studies in recent years have suggested that perihematomal tissue does exist many changes of pathophysiology and molecular biology,such as mass effect of hematoma,hematoma components damage to perihematomal tissue,hemodynamic changes, neuropeptide Y and matrix metalloproteinase changes,etc.

AIM: To evaluate the diagnostic accuracy of macular ganglion cell - inner plexiform layer ( GCIPL ) measurements using high- definition optical coherence tomography ( Cirrus HD - OCT ) ganglion cell analysis algorithm for detecting early and moderate to severe glaucoma.
METHODS:Twenty normal control persons, 26 patients with early glaucoma and 29 patients with moderate to severe glaucoma were enrolled in this study. Macular GCIPL, optic nerve head ( ONH ) parameters and peripapillary retinal nerve fiber layer ( RNFL ) thickness were measured in each subject. Then all measured results of each parameter were calculated using SPSS17. 0. Areas under the receiver operating characteristic curves ( AUC) of each parameter were calculated to compare the diagnostic accuracy for detecting early and moderate to severe glaucoma.
RESULTS: For detecting early glaucoma, AUC of average RNFL and seven clock value of RNFL were the biggest ( 0. 871 and 0. 896 respectively ), the AUC of parameters in GCIPL were also significant, among them,
the average GCIPL showed bigger AUC(0. 847) than the minimum GCIPL (0. 812). For diagnosing moderate to severe glaucoma, the AUC of rim area was 0. 992, which was bigger than that of average RNFL ( 0. 991 ). The minimum GCIPL showed bigger AUC ( 0. 983 ) than the average GCIPL (0. 967). For early glaucoma diagnosis, the sensitivity of average RNFL was the highest (76. 9%), while the average GCIPL has the highest specificity (93. 5%).
CONCLUSION: AS a new diagnostic parameter for detecting glaucoma, GCIPL shows similar diagnostic potential compared with RNFL. For early glaucoma diagnosis, average RNFL is the most important parameter, while screening early glaucoma, average GCIPL should be paid more attention.

Objective To compare the relativity between Tp-Te interval,Tp-Te /QT ratio with heart rate(HR)and explore their clinical significance retrospectively.Methods 200 normal individuals' ECG were randomly selected and the Tp-Te interval and Tp-Te/QT ratio were measured in precordial lead V6 retrospectively.The relativity between Tp-Te interval and Heart Rate,Tp-Te/QT ratio and Heart Rate were calculated retrospectively.Results The Tp-Te interval was about(83.17?12.64)ms in precordial lead V6 of normal individuals.The Tp-Te interval decreased linearly with the increase in HR with the range of Tp-Te interval being 56 to 114 milliseconds(Pearson's correlation coefficient r was-0.239,P=0.007 0.01).Conclusion There is an inverse correlation between Tp-Te interva and HR while no correlation between Tp-Te/QT ratio and HR.

Objective:To investigate the possibility of miR-125b in serum as a novel tumor marker for primary hepatocellular car-cinoma (HCC) and the diagnosis value of combined detection of miR-125b and alpha-fetoprotein (AFP) for HCC. Methods:We detected serum miR-125b expression of 65 cases of HCC patients and 30 cases of healthy controls by real-time quantitative PCR. Moreover, we analyzed the significance of miR-125b and explored the relationship between miR-125b and clinical pathological factors. Results:The level of miRNA-125b was down regulated in serum of HCC patients compared with healthy controls which showed significant differences (P<0.05). Furthermore, the expression of miRNA-125b has no distinct correlation with sex, age, HbsAg, AFP, ALT andα-GGT, which had no significant differences (P>0.05). The expression level of miRNA-125b correlated the difference with liver Cirrhosis, tumor size and tumor node metastasis (TNM) stages, which were considered significant differences (P<0.05). The receiver operating characteristic (ROC) curve analysis of serum miR-125b for the diagnosis of HCC yielded AUC of 0.917(95%CI:0.851~0.960, P<0.001)with 85.9%sensitivity and 93.5%specificity. The ROC curve analysis of combined miR-125b and AFP for HCC detection yielded AUC of 0.951(95%CI:0.894~0.982, P<0.001)with 92.9%sensitivity and 93.5%specificity. The ROC curve analysis of serum miR-125b as biomarkers for the group (AFP<20μg/L) of HCC yielded AUC of 0.889(95%CI:0.776~0.957, P<0.001)with 84.0%sensitivity and 87.1%specificity. Conclusion:Serum miRNA-125b combined with AFP has considerable clinical value for the early diagnosis of primary HCC.

Objective: To observe the difference in clinical efficacy between acupuncture with point selection based on syndrome differentiation along the meridians and acupuncture at non-meridian and non-acupoint points for functional dyspepsia (FD). Methods: A total of 74 FD patients were randomized into an observation group and a control group, with 37 cases in each group. Both groups received acupuncture treatment. Zusanli (ST 36) and Neiguan (PC 6) were selected in the observation group, with Taichong (LR 3) and Neiting (ST 44) added for excess syndrome, and Gongsun (SP 4) and Yinlingquan (SP 9) added for deficiency syndrome. Four non-meridian and non-acupoint points were selected in the control group. The treatments in both groups were performed once a day with a 2-day break after 5 consecutive treatments, which constituted one treatment course. A total of 4 courses were performed. The scores of Nepean dyspepsia index (NDI) and Leeds dyspepsia questionnaire (LDQ) were recorded before and after treatment, and during follow-up (8, 12, 16, 20 and 24 weeks after recruitment) to assess the clinical efficacy. Results: The NDI scores in the two groups after treatment and at each time point during follow-up were higher than those before treatment (all P<0.05), and the LDQ scores were lower than those before treatment (all P<0.05). The NDI scores after treatment and at each time point during follow-up in the observation group were higher than those in the control group (all P<0.01); the total LDQ score and scores of upper abdominal pain, postprandial satiety and upper abdominal burning sensation after treatment and at each time point during follow-up in the observation group were significantly lower than those in the control group (P<0.01 or P<0.05).. Conclusion: Acupuncture with point selection based on syndrome differentiation along the meridians has a better curative effect than acupuncture at non meridian and non-acupoint points in the treatment of FD.

BACKGROUND: Gallium is a non-essential trace element in the human body. In vivo experiments have confirmed that gallium can directly inhibit bone osteelysis, prevent bone calcium release, increase bone calcium content, serves as a new drug treatment of metabolic bone disease, its anti-bone transformation mechanism remains unclear. OBJECTIVE: To observe the effects of gallium nitrate on collagen and bone calcium protein in osteeporotic rat model. METHODS: Ninety female SD rats were divided into control group (n = 20) and osteoporosis group (n = 70) at random. Control group rats were sutured to close abdominal cavity after bilateral ovarian was exposed. Osteoporosis group rats received the bilateral ovariectomy to produce osteoporotic rat models, which then were assigned into 4 groups by random digits table: osteoporotic control group (n = 16) by intraperitoneal injection of saline, 3 times per week; Low-dose gallium salt group (n = 16) by intrapedtoneal injection of I mg/kg of galfium nitrate, 3 times per week; High-dose gallium salt group (n = 15) by intraperitoneal injection of 2 mg/kg ofgallium nitrate, 3 times per week; Estrogen group (n = 15) by intraperitoneal injection of estradiol, 3 times per week. After 12 weeks of the treatment, the bone collagen, osteocalcin protein and hydroxyproline levels in bone specimens were detected. RESULTS AND CONCLUSION: Compared with control group, the content of collagen in osteoporosis control group was reduced (P < 0.05), the contents of aminohexose and hydroxyproline increased (P < 0.05), no significant differences were observed in the content of sulfate-base for both groups. Following gallium and estradiol treatment, the collagen contents enhanced (P < 0.05), while the contents of aminohexose and hydroxyproline reduced (P < 0.05). High-dose gallium salt group had a remarkable curative effect compared with low-dose gallium salt group (P < 0.05), and was similar to estradiol group (P > 0.05). it is indicated that gallium nitrate can improve bone metabolism status with osteoporosis through increasing the content of collagen and decreasing the content of hydroxyproline, 2 mg/kg gallium nitrate are similar to estrogen treatment.

Objective To identify the rale of NKX2-5 gene in cardiomyocyte differentiation and its mechanism.Methods P19 cells were divided into transfected and non-transfected groups.In the transfected group,P19 cells were with stable expression of NKX2-5 gene.The P19 cells were cultured in suspension for 4 days,and the formed aggregates were transferred to Petri dish for adherent culture.On days 4,8,12,and 16 of the adherent culture,the expressions of ct-saicomeric actin(α-SA)and cardiac troponin T(cTnT)were detected with double-labeling immunofluorescence and Western blot.The ultrastruetural changes were observed on day 16.Results In the transfected group,no expression of α-SA and cTnT was found on day 4,and the expression of these 2 proteins or co-expression existed on days 8,12,and 16.There were early cell junction and myofilament-like structure in the cytoplasm of some cells in the transfected group.In the non-transfected group,these 2 proteins were negative,and no differentiated cell was found.Conclusion Stable expression of NKX2-5 gene can induce cardiomyocyte differentiation from P19 cells,but the P19 cells with stable expression of JVKX2-5 gene is not suitable to be an in vitro model of cardiac development.
