OBJECTIVETo systematically assess the efficacy and safety of Rhodiola in treating chronic stable angina pectoris.

METHODSOur group searched the Cochrane library, PubMed, Embase, Chinese biomedical literature database (CBM), VIP database (VIP), Chinese Journal Full-text Database (CNKI) for the literature published in English and Chinese till April 2013. Randomized controlled trials (RCTs) were included on the therapeutic effect of Rhodiola or Rhodiola plus conventional Western medicine in comparison with the conventional Western medicine treatment on stable angina. Data were extracted according the data extraction form. The literature methodological quality was assessed by using the Cochrane handbook, and data analyzed by Rev-Man 5.2 Software for Meta-analysis. The effect indicators of outcomes was expressed by odds ratio (OR) and 95% CI.

RESULTSA total of 7 randomized controlled trials, 662 cases of stable angina pectoris patients met the inclusion criteria and all published in Chinese, without one scientific design and high quality literature. Compared with the conventional Western medicine treatment, combined with oral administration of Rhodiola could improve the efficiency of anti-angina (OR = 2.49, 95% CI: 1.02 - 6.09). Combined with intravenous infusion of Rhodiola could also improve the efficacy of angina pectoris (OR = 4.86, 95% CI: 2.4 - 9.82). Oral administration of Rhodiola couldn't improve ECG efficacy (OR = 1.25, 95% CI: 0.67 - 2.34). Intravenous infusion of Rhodiola could improve the clinical efficacy (OR = 2.94, 95% CI: 1.61 - 5.35). Combined with the conventional treatment, intravenous infusion of Rhodiola could improve the whole blood viscosity (low and high shear rates) and inverse variance (IV) (-1.36 and -0.99, 95% CI: -1.65 - 1.07 and -1.26 - 0.71), but could not reduce serum fibrinogen and D-dimer level. The incidence rate of adverse reactions was higher than that of the conventional treatment combined with Rhodiola (OR = 0.1, 95% CI: 0.02 - 0.51).

CONCLUSIONSOn the basis of routine treatment, Rhodiola could further improve patients' symptoms. Combined with intravenous medication, Rhodiola could increase the ECG improvement rate, and reduce adverse reactions. But the methodological quality of included studies was poor, the number of samples was small, and influence factors such as the intervention period was short. This conclusion needs scientific and rational design in a larger sample, multicenter clinical trial to verify.

Objective To discuss anatomical characteristics and clinical results of the lateral superior genicular artery perforator iliotibial band flap. Methods From September 1999 to July 2009, the origin,course, branches and distribution of the lateral superior genicular artery and blood supply of iliotibial band were observed on 40 sides adult lower limbs perfused with red latax. Five perforator iliotibial band and 4 perforator iliotibial band flaps of 9 cases were treated with anastomosis of lateral superior genicular artery perforating rami. Results The lateral superior genicular artery of 35 cases (80%) originates from the popliteal artery. Its originated external diameter was (1.8 ± 0.4) mm. It divides into ascending branch and descending branch, and they gives off septofascio-cutaneous perforator, or anatomoses the lateral uppermost genicular artery in the vastus lateralis muscle, and then formes the musculocutaneous perforator of iliotibial band. The originated external diameter of the larger perforator of iliotibial bands was ( 1.0 ± 0.2) mm and they provides for the skin and iliotibial band of lateral superior genicular area. Nine cases, including 5 cases of simple Achilles tendon defects, two cases of achilles tendon defects with skin defects, and 2 cases of lower extremity and foot soft tissue defects were treated with transplantation of the vascularized iliotibial band (flap) with perforator vascular anastomoses. All cases were followed up 6 - 92 months. The results showed significant improvement in "heel test" and Thompson sign in the rerupture of the Achilles tendon occurred. Four perforator iliotibial band flaps survived well. Conclusion The lateral superior genicular artery perforator iliotibial band flap is a practical, simple and new donor in the reconstruction of soft tissue and composite defects.

OBJECTIVE: To observe the physiological and biochemical effects of intermittent fasting combined with hunger-resistant food on mice, and to evaluate the safety and beneficial effects of this regimen. METHODS: One hundred and forty-four adult ICR mice were divided into 4 groups: standard feed AL group (ad libitum intake of standard feed), hunger-resistant food AL group (ad libitum intake of hunger-resistant food), standard feed IF group (feeding standard feed and fasting on alternate days), and hunger-resistant food IF group (feeding hunger-resistant food and fasting on alternate days). The experiment lasted for 4-8 weeks and all mice drank water freely. The quality of life, body weight, fasting blood glucose, serum lipid, blood routine test, liver and kidney functions as well as the viscera indexes were examined. RESULTS: Compared to the standard feed AL group, the caloric taking and the increment of body-weight were reduced (P<0.01), and the viscera indexes of the liver and kidney were elevated (P<0.05) in the hunger-resistant food AL group and the hunger-resistant food IF group, the values of fasting blood glucose were reduced in standard feed IF group and hunger-resistant food IF group (P<0.01), the value of triglycerides was reduced in hunger-resistant food IF group (P<0.05), while the quality of life, blood routine test as well as the liver and kidney functions were not obviously affected in the hunger-resistant food AL group, standard feed IF group and hunger-resistant food IF group. CONCLUSION: The regimen of intermittent fasting combined with hunger-resistant food is safe and beneficial to metabolic regulation, such as controlling body-weight and adjusting blood glucose and serum lipid. It is expected that development of this regimen will be helpful to the control of obesity and diabetes, etc.

This study investigates the protective role of IMM-H004, a novel coumarin derivative, on hepatic ischemia-reperfusion injury (HIRI) in mice. All animal experiments in this paper have been approved by the Ethics Committee of Institute of Materia Medica, Chinese Academy of Medical Sciences. The experimental animals were divided into three groups, including sham group, model group, and IMM-H004 treatment group. Serum biochemical indicators were detected and H&E staining was used to assess liver damage. Real-time quantitative PCR (qPCR) was performed to analysis the mRNA content of inflammatory factors. Immunohistochemistry and immunofluorescence were used to observe neutrophil infiltration. Western blot was used to examine the protein levels of NOD-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein (ASC), cysteinyl aspartate specific proteinase-1 (caspase-1), and interleukin-1β (IL-1β). The results showed that IMM-H004 could significantly reduce the serum levels of alanine transaminase (ALT), aspartate transaminase (AST), lactate dehydrogenase (LDH). H&E results showed IMM-H004 could alleviate liver damage caused by HIRI. The mRNA expression of tumor necrosis factor-α (TNF-α), IL-1β, and interleukin-6 (IL-6) were decreased by IMM-H004 administration. Meanwhile, IMM-H004 could markedly inhibit neutrophil infiltration. Furthermore, IMM-H004 could significantly down-regulate the protein expression of NLRP3, ASC, caspase-1, and IL-1β, inhibiting the activation of NLRP3 inflammasome pathway. Our results confirmed that IMM-H004 could protect mice from HIRI and provide a theoretical foundation for IMM-H004 application for treating HIRI.

Objective To evaluate the role of real-time three-dimensional transesophageal echocardiography(RT-3D TEE)in left atrial appendage (LAA)occlusion.Methods Consecutive 10 atrial fibrillation (AF)patients (CHADS2 ≥ 2 )with high risk bleeding underwent LAA occlusion under the guidance of TEE.The LAA orifice shape and characteristics of lobes were assessed,the size of LAA with RT-3D TEE wee measured before closer implanation,and the position of the LAA occlusion device were evaluated by RT-3D TEE.The correlational analysis between LAA diameter and occluder size was conducted.Results Among 10 patients,the test results revealed 8 cases with complete LAA occlusion and 1 case with incomplete occlusion,and 1 case with failed occlusion.Five cases showed approximate round LAA ostium,and the other 5 showed approximate oval ostium.The average number of LAA lobes were 2.2±0.7. LAA ostium long diameter were larger by 3D TEE compared with 2D TEE[(21 .8±5.1)mm vs (20.8±4.1) mm],and ostium short diameter were smaller by 3D TEE compared with 2D TEE [(16.1 ± 3.0 )mm vs (1 7.0±2.6)mm],however there were no significant differences between 2D and 3D TEE measurements,and the mean ostium diameter and LAA depth were comparable between two methods.LAA ostium long diameter,short diameter,average diameter and LAA depth assessed by 3D TEE and 2D TEE showed good correlation with occluder diameter (3D TEE:r =0.719,0.690,0.791 ,0.71 1 ,and P =0.029,0.040,0.01 1 , 0.032,respectively;2D TEE:r = 0.887,0.894,0.932,0.896,and P = 0.001 ,0.001 ,0.000,0.000, respectively).LAA occlusion device position assessed by RT-3D:6 cases with appropriate position, acceptable position with 2 cases,and 1 case with malposition.Conclusions RT-3D TEE can play important role in evaluating the morphology of LAA,accurately judging LAA ostium shape and size and position of the occlusion device.

Objective To investigate the rat bone structural changes of lower limb following lumbar nerve dorsal roots section.Methods Forty-eight mature female Wistar rats were divided into posterior radi- cotomy(PR)and comtrol groups randomly.The bilateral femoral bone mineral density(BMD)and biome- chanics characteristics were analyzed 2,4 and 8 weeks after the radicotomy.The same operation except the radicotomy was done in the sham group.Results In PR group,2,4,and 8 weeks after the radicotomy,the BMD of femur was(0.221?0.008)g/cm~3,(0.213?0.015)g/cm~3 ,and(0.216?0.105)g/cm~3 ,respective- ly;while that was(0.223?0.005)g/cm~3,(0.218?0.014)g/cm~3 ,and(0.208?0.111)g/cm~3 in control group.No significant difference was observed between the two groups(P＞0.05).In PR group,2,4,and 8 weeks after the operation,the mean maximum load in three-point bending test of femun midshaft was(93.64?8.76)N,(89.77?11.18)N and(93.21?8.74)N,respectively,and was lower than the values of the con- trol group at the same time point(95.94?6.29)N,(91.63?9.43)N,(95.57?8.64)N,However,there was no significant difference between the two groups(P＞0.05).Accordingly,there was no significant difference in the energy absorption in femun midshaft between the two groups(P＞0.05).Conclusion The selective rhizotomies of part lumbar never dorsal roots might not cause the loss of the femur BMD and the change of bio- mechanics property significantly in short period.

Objective:To analyze the use status of antibiotics and the resistance of clinic isolate bacteria against the commonly used antibiotics before and after the intervention. Methods:Using the information retrieval systems, the consumption of antibiotics in the inpatients during the 1st quarter of 2012(before the intervention) and the same period of 2013(after the intervention) was com-pared. According to the defined daily dose ( DDDs) , the antibiotics were ranked, and the resistance rate against the commonly used antibiotics was analyzed. Results:Compared with the top ten before the intervention, the top ten after the intervention was changed sig-nificantly, however, cephalosporins was still the main species. After the intervention, the overall decline in DDDs was significant, the separation rate and distribution of bacteria remained stable. ESBLs enzyme production rate of Enterobacteriaceae Escherichia coli was re-duced by 7. 61%, and that of Klebsiella pneumoniae was reduced by 1. 34%, and the resistance rate against the commonly used antibi-otics was in an overall downward trend. The resistance rate of Gram-positive staphylococci against the commonly used antibiotics was de-creased, while that of Gram-positive enterococci showed notable difference. Conclusion:The DDDs of antibiotics and bacterial resist-ance rate are in an overall downward trend in our hospital after the intervention;however, there is still exception. Therefore, the clini-cal antimicrobial susceptibility tests should be performed as soon as possible to help the choice of antibiotics.
