Eighty two patients aged 60 or over with stable angina pectoris were randomized to control group ( n = 42, receiving conventional western medicine) and treatment group ( n = 40, receiving 1.5 g Songlingxuemaikang capsules three times a day in addition to western medicine) .The treatment was lasted for 12 weeks, angina classification of CCS, hs-CRP, blood pressure levels and SF-36 (36-item short form)of the patients were evaluated before and after the treatment.The degrees of angina pectoris in angina classification of CCS, hs-CRP and blood pressure levels decreased, and the quality of life was improved in both groups; but more markedly in treatment group than those in control group (P ＜ 0.05 ).Songlingxuemaikang capsule combined with conventional western medicine can effectively relieve the symptoms of ischemic chest pain in elderly patients with stable angina pectoris, which is associated with blood pressure reduction and life quality improvement.

Objective: To investigate the changes and significance of microvessel density(MVD) in bone marrow of patients with aplastic anemia. Methods: 30 aplastic anemia cases,20 hyperplastic anemia cases,and 20 normal individuals′ paraffin-embedded bone marrow biopsys were stained with HE and CD34 by immunohistochemistry method respectively;and the vol% of hematopoietic tissue area in bone marrows were detected accordingly. Results:The difference between the MVD of HE and CD34 was not significant in aplastic anemia cases ,and the difference between the MVD of HE and CD34 was not significant in normal individuals either. While the MVD of HE was significantly lower than that of CD34 in hyperplastic anemia cases. The difference of the MVD between light and heavy pathogenetic condition in aplastic anemia cases was significant.The MVD of CD34 were significantly different among the cases of aplastic anemia, hyperplastic anemia,and normal individuals.The MVD showed significant linear correlation with the vol% of hematopoietic tissue area (r=0.74,P

Objective To investigate the expression of kai1 and nm23 mRNA in esophageal carcinoma, and to explore the clinicopathological significance of kail and nm23 mRNA in the progression of esophageal carcinoma. Methods To detect mRNA expression of kai1 and nm23 in 46 cases of esophageal carcinoma and 34 cases normal esophageal tissues closely adjacent to carcinoma by in situ hybridization.Results The incidence of kai1 (91.3 %＞64.7 %, χ2 =8.65, P =0.003) and nm23 (43.5 %＞5.9 %, χ2=13.86,P ＜0.001) in esophageal carcinoma was significantly higher than in normal esophageal tissues . The expression of nm23 was correlated with the pathological stages (r =-0.379, P =0.009) and lymph node metastasis (χ2 =6.47, P =0.011). The expression of mRNA had positive correlation between kai1and nm23 in esophageal carcinoma (r =0.298, P =0.007). Conclusion The expression of nm23 may play an important role in the occurrence, development and clinicopathological features of esophageal carcinoma. Combined detection of kai1 and nm23 may be helpful in further directing the clinical therapy of esophageal carcinoma.

Objective To observe the clinical efficacy and safety of topical interferon alfa-1b cream in the treatment of herpes zoster. Methods A randomized, double-blind, parallel placebo-controlled clinical study was conducted. The test drug was topically used in herpes zoster patients, three times a day for 2 weeks. Patients whose skin lesions cleared completely were followed for 29 days to observe postherpetic neuralgia. Results One hundred and twenty-eight patients with herpes zoster were enrolled into this trial. Sixty-five patients were randomly selected to receive interferon alfa-1b cream and sixty-three patients received vehicle cream. After following up for 11, 14, 22, 29 days the cure rates were 69.2%, 81.5%, 90.8%, 95.4% respectively in the study group and were 57.1%, 71.4%, 84.1% and 84.1% respectively in the control group(P

It is estimated that epilepsy, a chronic disorder of the nervous system, affects about 0.5%-2% of the population and about 10%-50% do not respond well to current antiepileptic medications and may not be candidates for surgery. For these patients, the unpredictability of seizure onset is a major cause of disability and mortality. Therefore, anticipation of an imminent seizure would be beneficial to patients because it could provide time for the application of preventive measures to keep the risk of seizure to a minimum. This paper reviews the feasibilities, the progress, existing problems and possible applications in the field of epileptic seizure prediction.

Objective To investigate the effects ofWenyujinessential oil on tau protein phosphorylation in mice with Alzheimer Disease (AD); To discuss the relevant mechanism of action.MethodsSixty Kunming mice were divided into six groups randomly: sham-operation group, model group,Wenyujin essential oil low- and high-dose group, donepezil group andShenzhiling group.β-Amyloid protein (Aβ25-35) was infused into the hippocampal of mice. Mice in each group were given relevant medicine for gavage for 15 d. After the last administration, immunohistochemistry was used to detect the expressions of tau protein phosphorylation points (Ser 404 and Thr 231). Western blot was used to detect tau protein phosphorylation points and the expression of PI3K/Akt protein. Results Compared with sham-operation group, tau protein phosphorylation points in the model group increased (P<0.05), but the phosphorylation levels of PI3K and Akt decreased significantly (P<0.05). Compared with the model group, tau protein phosphorylation (Thr231 and Ser404) inWenyujin essential oil high-dose group decreased significantly (P<0.05), and the phosphorylation levels of PI3K and Akt increased(P<0.01). ConclusionWenyujinessential oil can inhibit tau protein phosphorylation in mice. The possible mechanism may be related to the PI3K/Akt signal pathway.

Objective To construct subsystem of picture archiving and communicating system (PACS) based on video database of ophthalmology and to evaluate on effectiveness of applying PACS system in postgraduate teaching.Methods PACS subsystem were constructed by collecting audiovisual materials of ophthalmology surgery videos,retinal photography,B-ultrasonography,OCT,UBM of patients.A total of 24 postgraduates were divided into control group (n =12) and experimental group (n=12) by random number table.Students in control group was taught by traditional cases,books and literature while those in experimental by network teaching from PACS subsystem.Two teaching methods were assessed subjectively and objectively.Objective indicators including ophthalmology examination results,operational skill ratings and paper reviewing results as well as subjective indicators including efficiency to accept the knowledge,satisfaction degree of teaching,influencing degree of papers were employed to assess the effectiveness of the two teaching methods.Independent samples t-test and twosample rank sum test were used for statistical analysis,P ＜ 0.05 was considered statistically significant.Results Students in experimental group done better in operation scores and in the assessment of the efficiency of knowledge accepting,satisfaction of teaching and papers effect than control group(P =0.000、0.000、0.000、0.003).The two groups had no significant difference in professional exam achievements and paper review scores (P =0.625、0.354).Conclusions PACS subsystem based on video database of ophthalmology are benefit for postgraduate teaching.

Objective To study the imaging findings of disseminated pulmonary tuberculosis in patients with acquired immunodeficiency syndrome (AIDS).Methods X-ray and multi-slice CT (MSCT)data from 33 AIDS patients with disseminated pulnonary tuberculosis confirmed by clinical manifestations and laboratory tests were analyzed retrospectively.Results Thirty patients underwent initial chest radiography examination,29 patients showed abnormal appearances,including bilateral disseminations in 21 patients and unilateral multiple disseminations in 8 patients.All patients underwent MSCT examination,26 patients showed bilateral disseminations and 7 patients showed unilateral multiple disseminations.The abnormal pulmonary appearances included nodule (n =25),miliary nodule (n =22),air-space consolidation (n =22),cavity (n =11),fibrosis (n =7),ground-glass opacity (n =7),pneumatocele (n =4),calcification (n =2).There were 20 patients with more than 3 abnormal appearances and 13 patients with one or two abnormal appearances.The extra-pulmonary tuberculosis included pleural effusion (n =33),lymphadenopathy (n =30),intestinal tuberculosis (n =3),splenic tuberculosis (n =1) and cerebral tuberculosis (n =1).Conclusion Disseminated pulmonary tuberculosis should be highly suspected in AIDS patients with diffused nodules,miliary nodules,air-space consolidations or multiple cavities,accompanied with pleural effusion and lymphadenopathy.

A device of extrahepatic portacaval shunt is introduced. This device is composed of the daughter and parent magnets and the vascular interventional operation equipment. It is based on the principle of magnetic compression technology, through the intervention approach the daughter and mother magnet are moved to the portal vein and inferior vena cava, respectively. Then the two magnets attract and compress the vessel walls of portal vein and inferior vena cava. Two weeks later, the magnets are detached from the vessel wall with a RUPS-set and the portacaval shunt is established. It is mainly used for the treatment of portal hypertension. It belongs to the interventional operation, there is no any foreign body remaining after the portacaval shunt is established, which can maintain long-term patency. Futhermore the portacaval shunt will not be expanded, therefore it can significantly reduce the incidence of hepatic encephalopathy.
