Objective To analyze the compatibility laws of homologous Chinese medicine of medicine and food in prevention and treatment of Alzheimer disease (AD). Methods We screened the clinical literature for the treatment of AD during 1988-2012 in TCM Clinical Diagnosis and Treatment Database, CNKI, VIP and Wanfang database. The nature, flavor, channel tropism, high frequency drug pair and compatibility laws of Chinese medicine and homologous Chinese medicine of medicine and food in prevention and treatment of AD were analyzed by frequency statistics and association rules. Results Two hundred and twenty-two clinical literatures were included. The top five frequently-used homologous Chinese medicines of medicine and food were Poria, Fructus Lycii, Fructus Alpiniae Oxyphyllae, Semen Persicae, and Rhizoma Dioscoreae. The top five frequently-used medicine were Rhizoma Acori Tatarinowii, Radix Polygalae, Rhizoma Ligustici Chuanxiong, Radix Salviae Miltiorrhizae, and Radix Angelicae Sinensis. The top five frequently-used drug pairs of homologous Chinese medicine of medicine and food were Rhizoma Dioscoreae→Poria, Poria→Pericarpium Citri Reticulatae, Rhizoma Dioscoreae→Fructus Lycii, Fructus Lycii→Fructus Alpiniae Oxyphyllae, and Fructus Lycii→Poria. The top five frequently-used drug pairs were Rhizoma Acori Tatarinowii→Radix Polygalae, Radix Salviae Miltiorrhizae→Rhizoma Acori Tatarinowii, Rhizoma Ligustici Chuanxiong→Rhizoma Acori Tatarinowii, Radix Salviae Miltiorrhizae→Rhizoma Ligustici Chuanxiong, and Rhizoma Acori Tatarinowii→Radix Astragali Seu Hedysari. Conclusion The commonly used homologous Chinese medicine of medicine and food in preventing and treating AD are tonic herbs with mild nature.

Objiective To evaluate the histocompatibility of gelatin-bletilla/Salvia-miltiorrhiza i material and to discuss the appropriate concentration of salvia-miltiorrhiza in the material. Method Salvia-miltiorrhiza together with gelatin and bletilla was used to make a kind of porous membranes. A total of 175 rats were divided randomly (random number) into 5 groups ( n = 35 in each). The porous membranes containing salvia-miltiorrhiza material in different concentrations of 1, 2, 4, and 5 mL/100 g were implanted subcutaneously into the rats of the four experimental groups, respectively. The gelatin-bletilla material without salvia-miltiorrhiza was implanted into the rats of control group. In 1, 3, 7, 14, 21, 28 and 56 days after implant, the materials were taken out of the bodies of the rats, separately. The material implanted for 1, 3, 7 and 14 days were observed with immunohistoche-mistry. Results In the area of implant, no noticeable inflammation or other was found. The implanted materials were degraded and entirely absorbed in vivo in 8 weeks. The salvia-miltiorrhiza in concentration of 2 mL/100 g in vivo promoted the angiogenesis most significantly. Conclusions The gelatin-bletilla/salvia-miltiorrhiza material has excellent histocompatibility and the appropriate concentration of salvia-miltiorrhiza in material is 2 mL/100 g.

Objective To evaluate the disease onset regions and spreading patterns in sporadic amyotrophic lateral sclerosis (ALS)patients and related influencing factors.Methods We performed a prospective analysis of 1 58 ALS patients.The disease-onset was confirmed according to the patients’self-reports,neurological examination results and electromyogram study.We followed up 1 5 1 patients with the second or other affected body regions during the disease progression.Data were analyzed according to the different groups of onset regions.Results 1.In 94.3% (149/1 58)of the patients,the early motor manifestations were focally in the bulbar,upper or lower limbs.2.The region of onset was associated with signs of lower motor neuron (LMN)and upper motor neuron (UMN)involvement (P = 0.000 ).The LMN involvement was more distinctive in patients with bulbar onset (65.4%,1 7/26 )group.Patients with cervical onset more frequently showed pure LMN (47.9%,45/94 )or concomitant UMN (52.1%,49/94)signs in the affected limbs.The highest proportion of UMN and LMN signs in the affected lower limb was found in the lumbar onset (83.8%,31/37 )group.3.Spreading patterns:Rostral to caudal spreading pattern was more frequent in bulbar onset patients.For patients with limb onset,there were significant differences between spreading patterns and disease-onset regions (P =0.04).Circular (31.5%,28/89),horizontal (30.3%,31/89)and vertical (21.3%,1 9/89)spreading patterns were more frequent in cervical onset patients whereas circular (47.2%,1 7/36)spreading patterns were more frequent in lumbar onset patients.4.There was a strong association between the rate of progression and age of disease onset (P =0.01 1).Patients aged over 60 had a faster progression.Conclusion ALS is a focal process at motor axis along the spinal cord and cerebral cortex.Different disease-onset can cause different distribution of UMN and LMN signs.Therefore,special attention should be paid to the signs of disease-onset clinically.ALS does start focally and spreads to adjacent regions.Elder patients have a faster disease progression.

Objective To investigate the influence of high-voltage electrical burn on the throm-bomodulin (TM), protein C (PC), protein S (PS) and D-Dimer (D-D) in SD rats. Methods One hundred and twenty healthy SD rats were divided into the fake high-voltage electrical burn groups (FHEB), high-voltage electrical burn groups (HEB) according to the random number table, with 60 rats in each group. Ten rats were taken from each group at 15 minutes before injury. Plasma were collected from heart blood. Fifty SD rats of HEB group with voltage regulator and experimental transformer. The remaining fifty SD rats of FHEB group were sham injured with the same devices without electric current. At 5 minutes and 1, 2, 4, 8 hour (s) post injury, 10 rats of every group were randomly chosen at each time point for observation of the concentrations of TM, PC, PS and D-D. Plasma were collected from heart blood. Data were processed with analysis of variance of factorial design and LSD test. Results Compared with the FHEB group, the concentration of TM from 5 minutes to 8 hours post injury in HEB group was higher significantly (P < 0.05). Exception of the concentrations of PC and PS at 15 minutes before injury, the concentrations of PC and PS were lower than those of FHEB group (P < 0.05). The concentration of D-D in HEB group peaked at 8 hours post injury in (173.05 ± 4.08) ng/mL. Conclusion High-voltage electrical burn at early stage can increase the concentrations of TM, D-D, as well as decrease the concentrations of PC and PS, which are not only causing the vascular endothelium damage but also possessing serious effect on the thromboplastin function of SD rats.

Objective To observe the regularities of distribution of TCM syndrome types and correlation between TCM syndrome types and cardiovascular prognosis risk factors of elderly hypertensive patients in three different urban and rural communities.Methods Totally 299 elderly hypertensive patients who conformed to the hypertensive diagnostic criteria from 896 respondents which participated in the health monitoring questionnaire drafted by health management team of China Academy of Chinese Medical Sciences were screened. The syndrome types were differentiated according to Guiding Principle of Clinical Research on New Drugs of Traditional Chinese Medicine (for Trial Implementation). The levels of some risk indicators, such as blood glucose, blood lipid, CREA, ET, Hcy and mALB were measured by radioimmunoassay, enzymatic cycling assay and other methods. Age, gender, BMI and pulse pressure were recorded.Results The TCM syndrome types of 299 elderly hypertensive patients were deficiency of yin and yang type (74 cases), hyperactivity of yang due to yin deficiency type (65 cases), blood stasis syndrome type (62 cases), stagnation of phlegm-dampness type (61 cases), hyperactivity of liver-fire type (37 cases). Single factor analysis showed that there existed statistical significance among BMI, FBG, GHbA1c, CREA, TC, LDL-C, ET, Hcy and mALB in the 5 TCM syndromes (P<0.05,P<0.01), and the statistical significance was more apparent in the stagnation of phlegm-dampness type, blood stasis syndrome type and hyperactivity of yang due to yin deficiency type. Discriminant analysis showed BMI and Hcy have certain reference value for the diagnosis of TCM syndrome types in elderly hypertensive patients. Binary-Logistic regression analysis showed that the course of disease had a positive correlation with syndrome of deficiency of yin and yang.Conclusion Compared with other types of elderly hepertensive patients, stagnation of phlegm-dampness type and blood stasis syndrome type are more closely related to hypertension cardiovascular prognosis risk factors.

Objective To observe whether calreticulin-induced mitochondrial dysfunction is involved in cardiomyocyte hypertrophy induced by angiotensin Ⅱ (AngⅡ).Methods Primary culture of neonatal rat cardiomyocytes was further confirmed by immunocytochemistry.The cardiomyocytes were randomly divided into model group,valsartan group and control group.The model group was subdivided into three groups which were separately treated with 1 0-8 mmol/L, 1 0-7 mmol/L, and 1 0-6 mmol/L Ang Ⅱ. Calreticulin expression, mitochondrial membrane potential level, enzyme activities, cell surface area and protein synthesis rate were observed.Results Cell surface area and protein synthesis rate were both increased in model groups compared with control group.Mitochondrial membrane potential level and enzyme activities were lower in model groups than in control group,while calreticulin expression was up-regulated.Pretreatment with valsartan partially reversed all the above changes.Conclusion Mitochondrial dysfunction induced by calreticulin may be an important mechanism of myocardial hypertrophy.

Objectives To investigate the role of lymphangiogenesis in the perineural micrometastasis of pancreatic adenocarcinoma. Methods The clinical data of 30 pancreatic adenocarcinoma patients who were admitted from Sep. 2005 to Oct. 2006 for extended radical surgery were collected. The samples including pancreatic cancer, adjacent tissue, lower bile duct, pancreatic tail, the structure surrounding the SMA (peripancreatic nerve plexus) and lymph nodes were collected during operation. They were subjected to conventional pathological examination. The lymphatic capillaries weredetected by double immunohistochemical staining and the lymphatic vessel density ( LVD) was measured. Results Intra-pancreatic and/or peripancreatic neural invasion was observed in 25 patients (83. 3% ) , of which 20 were found to have both the peri-pancreatic and intra-pancreatic neural invasion. The other 5 only had the intrapancreatic neural fiber invasion and there was no single patient with peri-pancreatic neural fiber invasion only. Peri-neural invasion was not significantly associated with patients' age, gender, lymph node metastasis, tumor size and the location (P > 0.05) , but was obviously associated with JPS clinical staging ( P < 0. 05 ). The mean intratumoral LVD was (4.2 ±3.4) per field, which was significantly lower than (11.3 ±6.9) per field of adjacent tissue and (10.8 ±4.4)per field of normal pancreatic tissue(P<0.01). The mean intratumoral LVD between adjacent tissue and normal pancreatic tissue was not statistically different. Lymphatic vessel invasion was observed in non-malignant tissues in 18 patients, and there was a distribution correlation between lymphatic vessel invasion and extra-pancreatic neural plexus invasion (P<0.05). Conclusions The incidence of peri-neural invasion was high, peri-neural invasion was associated with JPS clinical staging and lymphatic vessel invasion, which suggested the possibility of the cancer spreading by peritumoral lymphangiogenesis route into the peri-SMA neural plexuses.

Objective To construct a human endostatin adenovirus vector and investigate its inhibitory effect on pancreatic carcinoma in nude mice.Methods Animal model of pancreatic carcinoma bearing nude mice was established by subcutaneous injection of SW1990 cells.All mice were randomized into Ad-hEnd group,Ad-LacZ group and control group with 8 mice in each group.The endostatin gene recombinant adenovirus were intratumorally injected every two days for 4 times.The rate of tumor growth was observed.lmmunohistochemical staining was employed to investigate the expression of vascular endothelial growth factor (VEGF) and micro-vessel density (MVD).TUNEL in situ was used to examine tumor cell apoptosis.Results The tumor formation rate was 100%.4 weeks later,the volumes of the tumors were (921.9±279.7 )mm3,(2804.4±553.5 )mm3 and ( 3040.6±487.6 ) mm3 in Ad-hEnd group,Ad-LacZ group and control group,respectively;the weights of the tumors were (1.19±0.18 ) g,( 2.38±0.42 ) g and ( 2.41±0.47 ) g,respectively;the VEGF positive rates were (36.3±7.1 )%,(81.2±6.6)% and (79.4±6.2)%,respectively;the levels of MVD were 12±4,27±5 and 25±6,respectively;the apoptotic rates were (31.2 ±5.4) %,( 9.4±4.9 ) % and ( 8.5±3.7 ) %,respectively.Compared with Ad-LacZ group and control group,the parameters in Ad-hEnd group were statistically different (P ＜0.01 ).The difference betweon Ad-LacZ group and control group was not statistically different.Conclusions Human endostatin gene mediated by recombinant adenovirus could inhibit tumor growth,angiogenesis and promote cell apoptosis of pancreatic carcinoma and could be used as geue therapy for pancreatic carcinoma.
