Objective To analyze the medication rules of Chinese herbal concentrated-granule for the treatment of hypertension nationwide using data mining and knowledge graph methods,thus to provide evidence for expanding its application in treating hypertension.Methods From January 2022 to March 2023,Chinese herbal concentrated-granule prescriptions for hypertension prescribed by traditional Chinese medicine experts nationwide were collected.Microsoft Excel was used to analyze the frequency,properties and flavors,meridian tropism,and efficacy categories of the medicinals.Hierarchical clustering was applied for cluster analysis,and the Neo4j graph database was utilized to construct an information knowledge graph illustrating the relationships between regions and medicinals.Results A total of 2 600 Chinese herbal concentrated-granule prescriptions were included,involving 370 medicinals.The top six frequently-used medicinals were Poria(Fuling),Glycyrrhizae Radix et Rhizoma(Gancao),Atractylodis Macrocephalae Rhizoma(Baizhu),Citri Reticulatae Pericarpium(Chenpi),Paeoniae Radix Alba(Baishao),and Angelicae Sinensis Radix(Danggui).The properties of the medicinals were mainly warm and mild,and their flavors were usually sweet,pungent,and bitter.The medicinals frequently have the meridian tropism of the spleen,lung,and liver meridians.Hierarchical clustering yielded seven clusters.The information knowledge graph of region-medicinals relationships revealed that medicinals used in five or more regions were Baishao,Baizhu,Chenpi,Pinelliae Rhizoma(Banxia),Fuling,Gastrodiae Rhizoma(Tianma),Bupleuri Radix(Chaihu),Chuanxiong Rhizoma(Chuanxiong),Salviae Miltiorrhizae Radix et Rhizoma(Danshen),Danggui,Gancao,and Astragali Radix(Huangqi).Conclusion Chinese herbal concentrated-granule for hypertension usually consist of tonifying medicinals,with sweet and warm properties,and having the meridian tropism of the spleen meridian.And the medicinals composed of the prescriptions often have the actions of calming the liver and suppressing yang,strengthening the spleen and removing dampness,and nourishing the liver and kidney.

Objective To observe the effect of in situ needle fenestration thoracic endovascular aortic repair(TEVAR)for treating aortic dissection(AD)involving aortic arch.Methods Data of 16 patients with AD involving aortic arch who underwent in situ needle fenestration TEVAR for reconstruction of aortic arch branches were retrospectively analyzed,and the number of fenestration,technical success rate and TEVAR related complications were recorded.Regular follow-up was conducted after TEVAR,the repair of dissection and the patency of fenestrated branch blood vessels were evaluated,the endoleak was assessed,and the survival of patients were recorded.Results The main aortic stent was successfully implanted in all 16 cases.Among them,4 received triple fenestration stent implantation in zones Z0,Z1 and Z2,6 received double fenestration stent implantation in zones Z1 and Z2,2 received double fenestration stent implantation in zones Z0 and Z1 and 4 received single fenestration stent implantation in zone Z2.The success rate of brachiocephalic trunk(BCT)fenestration was 83.33%(5/6).Left common carotid artery(LCCA)-right common carotid artery bypass was performed in 1 case without successful fenestration.The success rate of LCCA fenestration was 100%(12/12).The success rate of left subclavian artery(LSA)fenestration was 87.50%(14/16),2 cases with not successful fenestration were treated with axillar-axillary artery artificial vascular bypass.The technical success rate of intervention was 100%(16/16).Type Ⅰa endoleak occurred in 1 case during TEVAR process and improved after embolization with spring coil.One patient died of pericardial tamponade at the end of TEVAR.Fifteen patients were followed up for a median follow-up time of 20 months.During this period,transient ischemic attack and local small dissection at the proximal beginning of the main stent occurred each in 1 case,which improved after no special treatment.Type Ⅰ endoleak occurred in 1 case,type Ⅲ endoleak occurred in 2 cases,all improved after proximal fenestrated membrane stent implantation or spring coil embolization treatment.One case died of coronary heart disease.Conclusion In situ needle fenestration TEVAR was effective and safe for treating AD involving aortic arch.

To study the effect of soybean isoflavone on liver oxidative stress resulting from 60Co-gamma rays. Methods: Totally 80 normal female Kunming mice were evenly randomized into 5 groups according to body weight: 3 intervention groups, single irradiation group and normal control group. The normal group and single irradiation groups were given 0.5% CMC-Na, and the 3 intervention groups were given different doses of soybean isoflavone (50 mg/kg, 100 mg/kg, 400 mg/kg) respectively for 14 d. The whole body of single irradiation group and intervention groups were subjected to 4.56 Gy 60Co-γ radiation once on the 7th day, and then the mice were killed on the 2nd day and the 7th day after radiation. Results: The CAT activity of liver tissue of 100,400 mg/kg intervention groups and 3 SI groups were significantly increased on the 2nd day and 7th day after irradiation(P<0.05), respectively; the GSH-Px activity of 100 mg/kg SI group was significantly increased(P<0.05) on the 7th day after irradiation; the T-SOD activity of 50 mg/kg SI group was significantly decreased (P<0.05) on the 2nd day after irradiation,while no difference was observed among remaining groups. The MDA content of 100 mg/kg group was significantly decreased on the 7th day after radiation compared with control group, and MDA content of each group subjected to irradiation were increased on the 2nd day after irradiation,but 3 SI groups nearly decreased to normal level on the 7th day after irradiation. Conclusion: The soybean isoflavone can enhance the antioxidant capability of mice, but it does not show a dose-effect relationship.

Objective:To observe the protective effect of tremella polysaccharides (TP) on mouse aging model induced by D-galactose. Methods: Forty male ICR mice were divided into 5 groups (Group A: treated with 800 mg/kg TP; Group B: treated by 400 mg/kg TP; Group C: treated by 200 mg/kg TP; Group D: aging control; Group E: normal control). Except for Group E,other groups were injected with D-galactose [120 mg/(kg?d)] for 60 d to establish subacute aging model. Group A,B and C were treated with 800,400 and 200 mg/kg TP respectively via intragastric (i.g.) administration. Sixty days later,the spleen,heart, kidney and brain were collected to determine MDA, LP, SOD, GSH-Px and contents of hydroxyproline by colorimetry. Expression of P21 in the kidney were detected by immunohischemical technique. Proliferation and transformation of spleen lymphocytes induced by ConA were determined by MTT method. Results: Antioxidants SOD and GSH-Px activity of TP treated groups were higher than aging control group (P

Objective To evaluate the nutritional status of morbid obesity (MO) before and after laparoscopic adjustable gastric banding (LAGB), and the safety of LAGB.Methods LAGB was performed in 15 cases from Jun.2003 to Nov.2003.Patients′ nutritional parameters were determined before and 1, 3 and 6 months postoperatively.Results There was a significant reduction of weight and body mass index (BMI) ( P 0.05).Conclusion No major nutritional deficiencies were found following LAGB.It is an effective and safe procedure for the treatment of morbid obesity.

In the present study the nutritional status in 1723 inpatients were evaluated. The over nutrition in male, in the cadre, and in patients with cerebrooardiovascular diseases or with diabetes was significantly higher than that in female, in the staff members, and the patient changing the valve in heart with rheumatism, respectively. The over nutrition in patients with breast and colonrectal cancer was obviously higher than that in stomach carcinoma patients. The sum total of lymphocytes was reduced in middle malnutrition patients. The nutritional status was well compared with the abnormal ratio of hemoglobin and serum protein, and A/G reverse was increased in some middle malnutrition patients. The MAC, MAMC and TSF in all of the malnutrition patients were than that of 80% standarized value, and were all the same in the evaluation of body weight.
