By studying the varieties of peony and analyzing the prescription of Huangqin decoction, the authors explored the differences between Paeoniae Radix Alba and Radix Paeoniae Rubra in varieties, origin, processing method and clinical efficacy and compare their efficacies to define Paeoniae Radix Alba or Paeoniae Radix Rubra in Huangqin decoction recorded in Treatise on Febrile Diseases. In the study, the authors clarified the development and change of the variety in various historical periods according to the earliest ancient herbal book recording the variety and the development sequence of main herbs, and made clear the relations between Paeoniae Radix Alba and Paeoniae Radix Rubra. The modern application of Paeoniae Radix Alba started in the Song Dynasty. Although it was processed in different ways from Paeoniae radix Rubra, they shared the same original plant varieties. On the basis of the historical origin, botanical origin, producing place and processing method, the authors made clear the evolvement of peony varieties, discussed and analyzed the developments and changes for the combined to the separate administration of Paeoniae Radix Alba and Paeoniae Radix Rubra and defined the peony variety in Huangqin decoction. Through the textual research on ancient herbal books, the authors confirmed that more than 2 000 years ago, Paeoniae Radix Alba didn't appear when Treatise on Febrile Diseases was written. According to the records in Miscellaneous Records of Famous Physicians that "its roots were collected and dried in February and August", it was inferred that the use of Paeoniae Radix Rubra conformed to the historical facts.

Objective To summarize the experience of diagnosis and treatment of iatrogenic injury by ureteroscopic surgery.Methods Retrospective analysis of 13 cases with iatrogenic injury by ureteroscopy from December 2008 to December 2011,including 8 men and 3 women,aged 15 to 75 years.Among the 13 cases (Holmium laser lithotripsy under ureteroscope),there were 5 cases of ureterostoma severe disruption,4 cases of submucosa injury,2 cases of perforation,1 case of disruption,and 1 case of sleeve exfoliation of mucosa.Results Among these 13 cases with iatrogenic injury by ureteroscopy,10 cases underwent double J drainage (drainage duration:60 days),and 3 cases underwent open surgery immediately.There was no hydronephrosis when examined by IVU after six months to two years follow-up.Conclusions The skills and techniques of surgical operation should be improved when performing ureteroscopic operation,and it is essential to be familiar with ureteric dissection and alignment,which can avoid ureteric injury.Indwelling D-J tube is very important in dealing with mild ureteral injury secondary to ureteroscopes.Surgical intervention should be given to severe cases of ureteric injury in time.

Objective To determine whether vascular endothelial growth factor (VEGF) could be used as a tumor marker by detecting the VEGF levels in serum and effusion from malignant tumor patients. Methods VEGF concentrations were measured using an enzyme-linked immunosorbent assay in the serum from the healthy donors and in the serum and the malignant effusion from the patients. Results The serum VEGF levels from the malignant tumor patients was higher than that from the healthy donors, and there was a significant difference ( P

In order to investigate the effect of Polo-like kinase-1 (Plk1) depletion on cell cycle progression and cell growth in lung cancer cells, a recombinant plasmid containing antisense RNA targeting Plk1 (pcDNA3-Plk1) was transfected into A549 cells by lipofectine. RT-PCR and Western-blot were used to detect the Plk1 gene expression. Cell proliferation was evaluated by direct cell counting and bromodeoxyuridine (BrdU) labeling. Cell cycle distribution and apoptosis were examined by flow cytometry, and the inhibition rate (IR) by vinorebline (NVB) was determined by MTT assay. The results showed that after transfection of pcDNA3-Plk1 into A549 cells, the expression levels of Plk1 mRNA and protein were greatly decreased. In pcDNA3-Plk1 transfected groups, abnormal morphological changes of cells and growth inhibition were observed, and the BrdU labeling index was significantly lower than in the control groups (P<0.05). Cells in pcDNA3-Plk1 transfected groups were arresed in G2/M phase and apoptosis was detectable 72 h post transfection. IR induced by vinorebline in pcDNA3-Plk1 transfected groups was significantly higher than in other groups. These data suggested that antisense RNA targeting Plk1 could suppress the Plk1 expression, and therefore, significantly inhibit cell proliferation and induce cell cycle arrest and apoptosis. Moreover, it sensitized lung cancer cells to chemotherapy.

Background Identifying and testing of pain is very necessary for the care and decrease of the suffering of experimental animal in medical experiment.Effective method for testing the pain and distress status of experimental animal with eye disease is still absent in China.Objective This pilot study was to establish an evaluating system for assessing the pain and distress status of bullous keratopathy rabbit model.Methods This study was approved by the Ethic Committee of Beijing University First Hospital.Twelve healthy New Zealand rabbits were selected in this experiment.Bullous keratopathy model was established in the left eyes of 9 rabbits by scraping corneal endothelium as the experimental team,and other 3 rabbits were served as the control team.The cornea lesion was examined by manipulate slit lamp,and the central cornea thickness (CCT) was measured by ultrasound biomicroscopy (UBM).Weight+20 Indexes For Pain and Distress Status Referring Guidelines for Pain and Distress in Laboratory Animals made by International Animal Care and Use Committee (IACUC) were assessed and measured as well.Results Corneal edema and opacity were obvious 1 day after surgery.Corneal bullous appeared from the third day after surgery,and cornea erosion was seen at the location of bullous breakage.The corneal lesions remained until 14 days after surgery.CCT value was (1468±100),(2313±588),(2391±271) and (2362±151) μm,respectively in day 1,3,7 and 14 after the establishment of models,which showed significant increase in comparison with the preoperative CCT (390±6)μm (all P=0.000).However,no significant difference was seen in the CCT between day 3,7 and 14 (P＞0.05).Body weight of the rabbits was (3.29±0.20),(3.20-0.17),(2.77±0.25) and (3.10±0.30)kg respectively in day 1,3,7 and 14 after operation,with significant decrease in comparison with the pre-operative weight (3.52-0.18)kg in the experimental team (P=0.008,0.007,0.003,0.004).The scores for pain and distress status of all rabbits in pre-operation of the experimental team and in the control team were zero,and the score was 7 (7,7),11 (10,12),9 (8,10),9 (9,9)in day 1,3,7 and 14 in the experimental team after surgery,with the highest score in day 3,which was bullous and bullous breakage duration.Seven of twenty indexes,including the reduce of diet and drinking,self-imposed isolation/hiding,grinding teeth,aggression,deceased movement,abnormal posture,vocalization occurred in the model animals after surgery.Conclusions Weight+20 Indexes For Pain and Distress Status is an effective,impersonal and quantitative method for observing and evaluating the pain and stress status in bullous keratopathy rabbit.

Objective To summarize treatment experiences of microsurgical clipping for anterior communicating artery aneurysm via pterional approach.Methods Clinical data of 82 cases undergoing microsurgical clipping for anterior communicating artery aneurysm via pterional approach in the first affiliated hospital of Kunming Medical University from October 2008 to December 2014 were collected and retrospectively analyzed.The patients were divided into different groups by Hunt-Hess illness grading scale,with 11 cases for level 0,7 cases for level Ⅰ,30 cases for level Ⅱ,25 cases for level Ⅲ,8 cases for level Ⅳ,and 1 cases for level Ⅴ.Twenty-one patients underwent operation at early stage of SAH (＜3d),15 at late stage of SAH (4d～2W),and 35 at prolonged stage of SAH (＞2W).The prognosis of patients was evaluated according to GOS classification criteria at discharge.Results A total of 85 ACoAA were found in 82 patients and all of them were clipped and,at the same time,3 aneurysms were resected and 11 thrombuses were punctured,cut and removed.In the operation,15 (17.6％) aneurysms ruptured again and temporary blocking happened for 73 times,with the shortest blocking time of 2 rmin,the longest of 40 rmin,and the average of 9.26min.According to GOS score,good recovery rate was 79.3％ (65/82),moderate disability rate was 12.2％ (10/82),severe disability rate was 3.7％ (3/82),vegetative state rate was 0％,and death rate was 4.9％ (4/82).Good recovery rates for the operations at early,late and prolonged stage of SAH were 85.7％,73.3％ and 82.3％ respectively and for level 0 to level Ⅴ were 90.9％,85.6％,86.7％ and 84.0％,25.0％ and 0.0％ respectively.Results of DSA or CTA re-examination upon 55 patients followed-up at discharge or three months after discharge showed that tumor pedicle were clipped and aneurysm disappeared.Fifty cases were followed up from four months to seven years after the operation,with one case of aneurysm recurrence.Another thirty-two cases were lost to follow-up.ConclusiornS Microsurgical techniques and microdissection are keys to successful operation.Pterional approach can guarantee successful clipping of aneurysms with different directions,locations and sizes.It is also an easy,effective and reliable approach with less postoperative complications.Operation for anterior communicating artery aneurysm should be performed as early as possible.

Objective To find out if different doses of melatonin have different roles in the cause or treatment of idiopathic scoliosis, and to illuminate whether melatonin can be a substitution in the treatment of pinealectomized chickens. Methods Fifty Little-Shaoxing chickens, in which pinealectomy was performed when 3-day-old, were divided into five groups. Ten served as control group, were kept in light-dark (12h: 12h) cycle, 500 lx in daytime and 0-5 lx in nighttime after surgery. Ten served as M-5 group, were given 5 mg/kg (5 milligrams per kilogram of body weight) melatonin twice every day. Ten as M-10 group, given 10 mg/kg melatonin abdominally twice every day, ten as M-20 group, given 20 mg/kg melatonin twice every day, and ten as M-40 group, given 40 mg/kg melatonin twice every day. The light-dark (12h: 12h) cycle was the same as control group. Radiological examinations were performed on all chicken spines for scoliosis when at 3 months old. Measured of the angle of the scoliosis was taken by Cobb's technique, and the data was analyzed by statistical software. Results Overall, there was 25 chickens developed to scoliosis in all when the chickens were 3 months. The attack rate was only 56%; this rate was consistent throughout all experimental groups. In the control group, 6 chickens had obvious scoliosis, and 5 in M-5 group, 5 in M-10 group, 4 in M-20 group, and 5 in M-40 Group. And the average Cobb's angle of control group was 26.7?. There were 23.5?, 21.7?, 24.5? and 23.2? in M-5, M-10, M-20 and M-40 respectively. There was no statistical significance in the average Cobb's angle and the incidence of scoliosis among all groups. It was determined that neither the prevalence nor the pattern of the scoliosis was affected by the therapy in any of the experimental groups. Conclusion Different dose of melatonin can't reduce the rate of scoliosis in the pinealectomized chickens, and also can't prevent the development of the experimental scoliosis. The results of this study raise doubts regarding the role of melatonin in the development of scoliosis after pinealectomy in the young chicken. Melatonin acting as a vicarious therapeutic tool in the treatment of idiopathic scoliosis is premature, deserved further research.
