Objective To investigate the protective effect of Ambroxol against experimental lung ischemia reperfusion (I/R) injury in a situ hilar clamp model.Method Left lung of rat was rendered and ischemic for 90 minutes,and reperfused for up to 2 hours,as the model.Twenty-four SD rats were randomly divided into 3 groups with 8 rats each group:control group,I/R group,I/R and Ambroxol treatment group (AMB group).Rats of AMB group received Ambroxol (25 mg/kg) Intraabdominally 30 minutes before ischemia and intravenously 5 minutes before reperfusion.After 2 hours of reperfusion,blood-gas analysis,the serum level of IL-1?,IL-8 and TNF-?from carotid artery were delected.The wet/dry ratio of lung,the activity of erythrocuprein (SOD),the content of malonaldehyde (MDA) and the activity of myeloperoxidase (MPO) were determined and pathematology changes were observed in the left lung tissue.Differences within the groups were analysed using two-sample t-test. Results After 2 hours of repeffusion,there were no significant changes of artery partial pressure of oxygen (PO_2) and partial pressure of carbon dioxide (PCO_2) among three groups.The wet/dry ratio of lung,the activity of MPO (U/g) and the content of MDA (nmol/mgprot) of I/R group were (5.3?0.5),(1.30?0.26) and (0.66?0.16),significantly higher than those of the control group (P

Objective To investigate the application of multi-slice spiral computed tomography(MSCT) in the diagnosis of solid pseudopapollary tumor of the pancreas (SPTP). Methods Clinical data and CT films of 12 patients with SPTP were retrospectively analyzed from January 2003 to December 2008. Results SPTP presented a typical cystic lesion with well-limited silhouette and no intensification in the cyst on enhanced CT scan. However, a slight to moderate enhancement in the solid components and a markedly enhanced envelope could be seen. Three dimensional images of MSCT can reveal clearly an anatomic relationship of the lesions with surrounding organs and blood vessels. Of 12 cases, there was one case showed that the envelope was incomplete, 3 with duodenal invasion, 2 with superior mesenteric vein involvement, and 1 with closed adhesion with spleen. All 12 patients underwent surgery and had only one tumor, tumor diameter ranged from 4 cm to 18 cm. The location of tumor in pancreas, the relation with surrounding tissue and the pathological presentation were helpful to make peroperative diagnosis. Three dimensional imaging technology of MSCT can offer important referrence for the preroperative evaluation and increase the diagnosis accuracy.

OBJECTIVETo compare the difference in the long-term efficacy between all-trans retinoic acid (ATRA) combined Compound Huangdai Tablet and ATRA combined methotrexate (MTX) and 6-mercaptopurine (6MP) as the sequential maintenance treatment of acute promyelocytic leukemia (APL) patients.

METHODSTotally 83 APL patients in the molecular remission (PML/RARalpha negative) were randomly assigned to two groups, the treatment group (45 cases) and the control group (38 cases) after they were induced to the complete remission (CR) by ATRA combined chemotherapy, and treated by sequential chemotherapy as the consolidated treatment for 3 therapeutic courses. Those in the treatment group were sequentially treated with ATRA and Compound Huangdai Tablet as maintenance therapy, while those in the control group were treated with ATRA and MTX + 6MP as maintenance therapy. After a long-term follow-up (2003 -2011), the long-term therapeutic efficacy and adverse reactions were compared between the two therapeutic regimens.

RESULTSThe 5-year relapse-free survival (RFS) rate was 84.4% +/- 5.4% in the treatment group and 63.2% +/- 7.8% in the control group, showing statistical difference between the two groups (P < 0.05). The 5-year overall survival rate (OSR) was 86.7% +/- 5. 1% in the treatment group and 78.7% +/- 6.7% in the control group, showing no statistical difference between the two groups (P > 0.05). There was no statistical difference in the adverse reaction between the two groups (P > 0.05).

CONCLUSIONThe application of ATRA and Compound Huangdai Tablet as maintenance therapy could elevate the long-term RFS rate of APL patients.

ObjectiveTo detect the changes of gastroesophageal reflux disease (GERD) with high resolution endoscopy,and to explore its diagnostic value for nonerosive reflux disease (NERD). Methods From April 2007 to January 2008, consecutive out-patients visiting the Department of Gastroenterology due to continuous or recurrent symptoms of acid reflux, heartburn, cardiac-like chest pain for at least three months and volunteer healthy controls were recruited to the study. The subjects were classified into the normal group ( n =48 ), the NERD group ( n =70), the erosive esophagitis (EE) group ( n =70), and the Barrett esophagus (BE) group ( n =48). All subjects underwent endoscopy, and the shape of Z-lines, the shape of mucosal pits, mucosa roughness above Z-line and the shape of mucosal blood vessels were observed. The NERD changes were analyzed with optimal scale. ResultsZ-line shape of NERD group showed a significant difference from that of EE and BE groups ( P ＜ 0. 01 ), which was not different from that of normal controls ( P ＞0. 01 ). The shape of mucosal pits of NERD group was different from that of EE and BE (P ＜0. 01 ), which also was not different from that of control (P＞0. 01 ). Roughness of the mucosa above Z-line of NERD group was different from other 3 groups (P ＜0. 05). And the shape of mucosal blood vessels of NERD was different from the control (P＜0. 05), but was not from two others. Features of NERD relative images were thin,straight and spiral blood vessels, bar-like pits, plat mucosa, round, smooth and wide tooth-like Z-line and mucosa of white particle hypertrophy. ConclusionHigh resolution endoscopic features of most NERD patients are cloudy, white and rough mucosal surface, with white particular hypertrophy, spiral vascular dilation, extending to Z-line. These features can be indicators of NERD.

Objective To evaluate the curative effect of stretching therapy combined with oral administration of Chinese herbal medicine Tongjing Powder in treating dysmenorrhea patients with Qi stagnation and blood stasis. Methods Sixty dysmenorrhea patients were randomly divided into two groups, 30 cases in each group. Treatment group was given oral use of Tongjing Powder (mainly composed of Radix Angelicae Sinensis, Rhizoma Chuanxiong, Radix Paeoniae Alba, Rhizoma Cyperi, Aspongopus, Radix Salviae Miltiorrhizae, Pollen Typhae, Faeces Trogopterori, Rhizoma Curcumae, and Semen Persicae) combined with stretching therapy. The control group was given oral use of Tongjing Powder alone. Each group was treated for 3 menstrual cycles. Visual Analogue Scale (VAS) scores of dysmenorhea were observed during the treatment and 3-month follow-up after treatment. Before and after treatment, pulse index (PI), resistance index (RI), the ratio of systolic peak value to the diastolic peak value (A/B) of uterine artery blood flow in the two groups were detected. And the clinical efficacy of the two groups was evaluated after treatment. Results (1) The VAS scores of the two groups after treatment and at the end of the third menstrual cycle after treatment were significantly lower than those before treatment(P<0.05), and the decrease in the treatment group was superior to that in the control group(P < 0.05).(2) After treatment for 3 menstrual cycles, the total effective rate was 96.7％ in the treatment group, which was higher than that in the control group(76.7％). And the difference was statistically significant(P < 0.05). (3) The color Doppler energy (CDE) imaging results showed that PI, RI, A/B of uterine artery blood flow in the two groups were decreased after treatment (P < 0.05 compared with those before treatment) , but the differences between the two groups were insignificantly(P > 0.05). Conclusion Stretching therapy combined with oral administration of Chinese herbal medicine Tongjing Powder exerts certain short-term and long-term effect in treating dysmenorrhea patients with Qi stagnation and blood stasis, with good safety and feasibility.
