Objective: To identify Rehmanniae Radiuxand its closely related species using the ITS2 barcode and to guarantee the quality and clinical curative effect of this medical material. Method: The sequences has been ana-lyzed and assembled using corresponding software. The Kimura 2-Parameter (K2P) distances were calculated and NJ (neighbor-joining) tree was established based on the K2P methods to identify the Rehmanniae Radix. Results:The length of the ITS2 sequence of Rehmanniae Radix was 231 bp. The average intra-specific genetic distances of Rehmanniae Radix were 0.0004. The average inter-specific genetic distances between Rehmanniae Radix and its closely related species were 0.0312. The minimum inter-specific divergence is larger than the maximum intra-specific divergence. The Rehmanniae Radix can be identified using the NJ trees method. Conclusions: The ITS2 sequence can be used as DNA barcode to identify Rehmanniae Radix and its closely related species, which will lay the foundation for the clinical medication safety of Rehmanniae Radix.

Chinese Medical Sciences Journal 2014;(3):139-143
Objective To explore the perihematomal perfusion typing and spot sign on computed tomography angiography (CTA) source images in order to assist in individualizing therapeutic decisions for patients with intracerebral hemorrhage by possibly forecasting perihematomal ischemia and hematoma enlargement.
Methods We examined 58 patients with spontaneous intracerebral hemorrhage by computed tomography perfusion and CTA within 6 hours after symptom onset. Hematoma volumes were determined from non-contrast CT images and compared between first and second CT images. The perfusion of hematoma region and perihematoma region was evaluated for presence or absence of the perihematomal penumbra. Three kinds of perihematoma perfusion typing were defined according to the perfusion of hematoma region and perihematoma region. CTA source images was reviewed to make sure presence or absence of the spot sign.
Results Finally, 53 patients (34 males, 19 females) were enrolled in our study according to exclusion criteria. Finally, 21 patients were classified into the normal group, 23 patients were classified into the mild group, and 9 patients were classified into the severe group. There were significant differences in hematoma size between the presence and absence of the perihematomal penumbra group (P<0.05). Thirteen (24.5%) patients presented with spot sign. Hematoma expansion occurred in 15 (28.3%) patients on follow-up. In which 12 patients were with spot sign. Sensitivity, specificity, positive predictive value, and negative predictive value for expansion were 80.0%, 97.4%, 92.3%, and 92.5%, respectively.
Conclusion In acute intracerebral hemorrhage patients, the perihematoma perfusion typing and CTA spot sign provide more radiological information that might assist in individualizing therapeutic decisions for patients by possibly forecasting perihematomal ischemia and hematoma enlargement.

Objective To investigate the associations of baseline serum uric acid, bilirubin levels with short-term outcome in patients with acute ischemic stroke. Methods The clinical data in successive patients with acute ischemic stroke were colected, including the serum levels of uric acid and bilirubin on admission, the National Institutes of Health Stroke Scale (NIHSS) score, and the modified Rankin scale (mRS) score at discharge or at day14 (mRS 0-2 was defined as good outcome, > 2 was defined as poor outcome). Results A total of 162 patients with ischemic stroke were enroled, including 114 in the good outcome group and 48 in the poor outcome group. There were significant differences in proportions of the patients with diabetes melitus (51. 75% vs. 75. 00% ; χ2 = 7. 526, P = 0. 006), previous history of stroke or transient ischemic attack (TIA) (18. 42% vs. 50. 00% ; χ2 = 17. 790, P = 0. 001), as wel as the baseline diastolic blood pressure (87. 061 ± 12. 245 mmHg vs. 82. 375 ± 10. 949 mmHg; t = 2. 293, P = 0. 023; 1 mmHg =0. 133 kPa), high-density lipoprotein cholesterol (1. 604 ± 0. 299 mmol/L vs. 1. 265 ± 0. 206 mmol/L; t =3. 227, P = 0. 002), fasting glucose (2. 875 ± 0. 438 mmol/L vs. 8. 160 ± 0. 592 mmol/L; t = - 4. 761, P <0. 001), uric acid (289. 365 ± 77. 168 μmol/L vs. 248. 206 ± 66. 206 μmol/L; t = 3. 111, P = 0. 002), total bilirubin (14. 673 ± 2. 213 μmol/L vs. 10. 395 ± 2. 714 μmol/L; t = 3. 779, P = 0. 001 ), direct bilirubin (6. 036 ± 1. 392 μmol/L vs. 4. 956 ± 1. 379 μmol/L; t = 2. 088, P = 0. 038), and indirect bilirubin (8. 634 ± 2. 307 μmol/L vs. 5. 439 ± 1. 223 μmol/L; t = 4. 219, P < 0. 001) levels between the 2 groups. Multivariate logistic regression analysis showed that the previous history of stroke or TIA (odds ratio [ OR ] 3. 751, 95% confidence interval [CI ] 1. 395-10. 091; P = 0. 009) and baseline NIHSS score (OR 2. 723, 95% CI 1. 093-6. 783; P = 0. 031) were the independent risk factors for poor outcome of ischemic stroke; while uric acid (OR 0. 357, 95% CI 0. 141-0. 900; P = 0. 029), high-density lipoprotein (OR 0. 262, 95% CI 0. 079-0. 870; P = 0. 029), and indirect bilirubin (OR 0. 117, 95% CI 0. 025-0. 539; P = 0. 006) were independently correlated with good outcome. Conclusions The increased baseline uric acid and indirect bilirubin levels are the favorable factors for good outcome in patients with acute ischemic stroke.

OBJECTIVETo explore the effects of moxibustion with seed-sized moxa cone at "Ganshu" (BL 18) on liver furiction and morphology in rat with precancerous lesion of hepatic cellular cancer MCC).
METHODSA total of 60 male Wistar rats were randomly divided into a normal group (10 rats), a model group (20 rats), a 20-day treatment group (15 rats) and a 40-day treatment group (15 rats). HCC model was established by intraperitoneal injection of diethylnitrosamine (DEN). Rats in the normal group received no treatment. Rats in the model group were treated with fixation. Rats in the 20-day treatment group and 40-day treatment group were treated by moxibustion with seed-sized moxa cone at "Ganshu" (BL 18), once every other day, for 20 days and 40 days, respectively. Blood sample in each group was collected 1 d before model establishment, 20 d, 40 d and 84 d after model establishment. Chemical method was applied to test the activity of ALT (alamine aminotransferase), AST (aspartate transaminase) and GGT (glutamyl transpeptidase); at the end of model establishment, all the rats were sacrificed to observe the liver morphology changes.
RESULTSAfter the first therapeutic course, the. content of ALT and AST in the 20-day treatment group was significantly lower than that in the model group (all P<0. 05); after the second therapeutic course, the content of ALT, AST and GGT in the 40-day treatment group was insignificantly lower than that in the model group (all P>0. 05). Under light microscope, the slice of liver tissue indicated that primary tumor was induced in the model group, and the tumor cells were stained and irregular; the cytoplasm in the 20-day treatment group was even, and the tumor cells were few with several nodules alone. In the 40-day treatment group the liver morphology was normal and the staining was even; the tumor cells were few without nodules or a few. Conclusion Moxibustion with seed-sized moxa cone at "Ganshu" (BL 18) could reduce the serum content of ALT, AST and GGT in rats with HCC, which could protect the liver and: delay the DEN-induced precancerous lesion on some levels.
