OBJECTIVE:To optimize the dry granulation technology conditions for Yinqiao baidu tablet. METHODS:Using granulating difficulty degree and disintegration time as investigation indexes,ratio and amount of accessories microcrystalline cellu-lose and compressible starch in Yinqiao baidu tablet,moisture content of the sprayed powder were screened. Using yield of particle and angle of repose as indexes,L9(34)orthogonal test was used to optimize the wheel pressure,rotating speed and feeding speed in dry granulation technology,and verification test was conducted. RESULTS:The ratio of microcrystalline cellulose and compress-ible starch was 7:3,and mixing ratio of the two with spray powder+inclusion compound was 1:5. The moisture content of spray powder was controlled in 1%-2%. The optimal technology was as follow as wheel pressure of 3.5 MPa,roller speed of 4 r/min and feeding speed of 10 r/min. In verification test,average yield of particle was 69.2% and angle of repose was 31.5 °. Transfer rate of chlorogenic acid had reached over 92%,and RSD of each index was below 2.53%(n=3). CONCLUSIONS:Each index of parti-cle prepared by optimized accessories formulation and technology shows good reproducibility and feasibility,and the technology is stable and suitable for production.

Objective:To explore the clinical diagnosis and treatment methods for nasal septum malignancies. Methods:A retrospective study of seven cases of primary nasal septum malignancy was conducted. These cases were treated at the Tianjin First Central Hospital between February 1993 and October 2009. Results:Among the seven cases, one was reported malignant lymphoma, which underwent chemotherapy and radiation therapy;the other six malignant tumors included three cases of adenoid cystic carcinoma, one malignant melanoma, one chondrosarcoma, and one papilloma. Patients were treated by nasal endoscopy, external approach, lip midline incision, overturned facial surgery, chemotherapy, and radiation. During follow-up, which lasted for 2 years to 16 years from time of surgery, two fatalities resulting from recurrence or metastasis were recorded. One of these fatalities occurred after 2 years, and the other was recorded at 3 years and 4 months after surgery. Four patients survived without recurrence. Conclusion:The key treatment for nasal septum malignancies was one-time radical resection. Combined postoperative treatment and follow-up should be conducted.

Objective To investigate the relationship between the C825T polymorphism of G protein β3 subunit (GNB3) and essential hypertension and cerebral infarction patients with a history of hypertension. Methods The C825T polymorphism of GNB3 was determined by polymerase chain reaction-restriction fragment length polymorphism in 110 healthy subjects aged over 40 years, 92 patients with essential hypertension, and 80 cerebral infarction patients with a history of hypertension. Sex, age, family histories of diabetics, smoking and alcoholic consumption were documented, and body mass index, waist-hip ratio, total cholesterol (TC),triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and fasting blood glucose concentration were measured. A multivariate logistic regression analysis was used to screen the factors associated with the occurrence of cerebral infarction in patients with hypertension.Results The distribution of the C825T polymorphism of GNB3 in the 3 groups all met the Hardy-Weinberg Law of genetic equilibrium. The genotype frequencies of CC, CT and TT in cerebral infarction patients with a history of hypertension were 33%, 57%, and 20%, respectively; those in patients with essential hypertension were 33%, 42%, and 25% ; respectively;and those in the control group were 26%, 54%, and 20%, respectively. There were no significant differences (x2 =4. 030, P =0. 402). The allele frequencies of 825T in the 3 groups were 39%, 40%, and 47%, respectively. There were no significant differences (x2 =0. 832). A multivariate logistic regression analysis showed that TC (odds ratio [ OR] 10. 810, 95% confidence interval [ CI] 2. 64544. 136, P =0. 000), TG (OR 5. 453, 95% CI 1.662-17. 881, P =0. 005),HDL-C (OR, 0. 181, 95% CI 0. 041-0. 795, P = 0. 027), blood glucose (OR 2. 386, 95% CI1.062-5. 363, P =0. 035), and diabetes (OR 7. 156, 95% CI 1.271-40. 291, P =0. 026) were the independent risk factors for cerebral infarction, and the GNB3 genotype and allele did not enter the model. Conclusions The C825T polymorphism of GNB3 may not be associated with cerebral infarction and essential hypertension.

BACKGROUND: Stroke in progression(SIP) accounts for 26% -43% of cerebral infarction. It is a common clinical stroke subtype. However, there are no effective treatments to stop the progress with higher mortality rate and invalid rate. More attentions have been paid for multiple risk factors of cerebrovascular diseases during precaution and treatment. But the study on relationship between infection and stroke occurrence, and the inhibited clinical event with antivirus druggery is just at the beginning.OBJECTIVE: To investigate the correlation between clinical SIP characteristics and herpes virus(HSV) infection, and provide the clues to the SIP diagnosis and treatment and early rehabilitation.DESIGN: Case-control study based on patients.SETTING: Department of neurology in a university hospital and a microbiological department in a university.PARTICIPANTS: Totally 47 patients with progressive stroke hospitalized in Department of Neurology, the Second Hospital of Hebei Medical University during April 2001 to March 2002[21 males, 26 females; aged from 15 to 78 years, mean age of(53.12 ± 2.45) years] . There were 43 cases of limb paralysis (92%), 7 cases of aphasia, 4 cases of consciousness disturbance, 1 case of epileptic seizure, 1 case of hemianopia, 5 cases of ataxia, and 24 cases of dizziness. The diagnosis of cerebral infarction was confirmed with CT and/or MRI. The patients clinical pregresively aggravated over more than 72 hours from the stroke onset. And it was not able to stop the aggravation of the situation with conventional treatment. The patients with embolism and reversible ischemic neurological deficit(RIND), cerebral hemorrhage, hemorrhagic infarct were excluded; Patients with other severe diseases such as coronary heart disease, cardiac atrium fibrillation, severe diabetes, hypertension, and the history of illness more than 5 years were excluded. Totally 193 patients were selected as control group with non-cerebrovascular disease, included headache, insomnia, neck and shoulder pain[ 100 males, 93 females, aged from 26 to 60 years,mean age of(42.23 ±9.29)].of the Fourth Scholarship Meeting of Cerebrovascular Diseases in China in tected by MRI, 44 cases detected by magnetic resonance angiography(MRA), 4cases detected by digital subtraction angiography (DSA), and 8 cases detected levels of IgM of human cytomegalovirus(HCMV) and herpes virus(HSV) in serum of 47 patients with progressive stroke and 193 patients without cerebrovascular disease were detected by dot immunogold labeling staining (IGLS); Stromatin PP65 antigen of HCMV in marrow cell were detecting by of the situation with the conventional treatment. PFA 250 mL(3.0 g) was given once a day from 14 to 21 days and dexamethasone 5 - 10 mga day for 3 to 7 days.after treatment with antivirus druggery.dot low-density plaques in cortex or subcortex of cerebral lobes, were found in were found positive in 91% of the patients and the level of IgM in patients PFA was effective.of cerebral lobes, and stenosis or occlusion in cerebral arteries or major infection and progressive stroke.

OBJECTIVE:To establish the quality standard for the leaves of Nauclea officinalis. METHODS:Microscopic identi-fication and TLC methods were used for qualitative identification of N. officinalis. The moisture and ash of medicinal materials were determined. HPLC method was adopted to determine the content of strictosamide in medicinal materials. The determination was per-formed on Lichrospher C18 column with mobile phase consisted of acetonitrile-0.1% phosphoric acid solution(gradient elution)at the flow rate of 1 mL/min,injection volume was 10 μL. The detection wavelength was set at 226 nm,and the column temperature was 30 ℃. RESULTS:Microscopic identification of the leaves of N. officinalis had strong characteristics,and TLC sports were clear and well-separated without interference from negative control. The linear range of strictosamide were 0.0105-0.21 mg/mL(r=0.9995);RSDs of precision,stability and reproducibility tests were all lower than 2.0%. Average recoveries were 96.25-101.82%(RSD=1.86%,n=9). Total ash of medicinal materials was 5.27%-6.44%,acid insoluble ash was 0.23%-0.36%,water content was 9.48%-11.46%,strictosamide was 0.124%-1.003%. CONCLUSIONS:Established standard can be used for quality evaluation of N. officinalis.
