OBJECTIVETo study the clinical efficaly and safety of Tiepi Fengdou Granule (TFG) and Capsule (TFC) combined with chemotherapy and/or radiotherapy in treating lung cancer patients with Qi-Yin asthenia syndrome (QYAS).

METHODSEighty patients were randomly assigned into 3 groups: the TFG group (32 cases), the TFC group (32 cases) and the Shengmai Capsule control group (16 cases). Changes of symptoms of QYAS, main symptoms of lung cancer, Karnofsky scoring as well as the blood routine test were observed.

RESULTSThe total effective rate of symptom improving in the TFG group and the TFC group was 81.2% and 93.3% respectively, showing insignificant difference between the 2 groups (P > 0.05), but both were higher than that in the Shengmai Capsule control group (50.0%, P < 0.05 and P < 0.01). Additionally, as compared with those before treatment, the neutrophil count increased and the lymphocytes count obviously decreased in the TFC group after treatment (all P < 0.05).

CONCLUSIONBoth dose-forms of the remedies, TFC and TFG, have significant effects in treating lung cancer with QYAS, but with insignificant difference between them.

OBJECTIVETo investigate therapeutic effects of vacuum sealing drainage (VSD) in the treatment of soft tissue defect combined with tendon and bone exposure.

METHODSFrom October 2007 to February 2011, 397 patients (412 feet) with open ankle fracture and dislocation combined with soft tissue defected were treated by VSD. There were 301 males and 96 females with an average age of 36 years (ranging age from 20 to 73 years). According to AO classification, 74 feet were type I, 211 feet were type II, 108 feet were type III and 19 feet were type IV. The mean time from injury to operation was 5.6 h ( 2 to 12 h). The mean treatment time of was 10 months (4 to 19 months).

RESULTSOne hundred and forty-one patients were primarily healed, 97 patients were sutured at stage II. Split-thick skin grafting was performed at stage II was performed in 103 patients; free flap transplantation was performed in 25 patients. Three of the 34 patients with infection were removed steel plate; Eviscerate flap coverage wound was performed in 14 patients caused by the first metatarsal bone exposure; Toe amputation were performed in 22 cases caused by toes necrosis. Tarsometatarasl joints perforators' surgery was performed in 10 patients with forefeet necrosis. Thirty hundred and six patients were followed up from 3 to 20 months (averaged 10 months). The wounds healed well.

CONCLUSIONVSD for soft tissue defects caused by ankle injury is a simple and effective method, but can not replace debridement and transfer flap.

Objective To study the mutagenic action of antiepileptic drugs(AEDs), and find an effective way to prevent the mutagenesis induced by AEDs,by observing the effects of AEDs on serum folic acid(FA) level and sister chromatid exchange (SCE) frequency in epileptic children.Methods Ninty epileptic children were divided into different groups on the basis of the different drugs they had taken, then detected the two indexes at different time points.Results The serum FA level and SCE frequency of the patients significantly decreased and increased after they took carbamazepine (CBZ) and valproic acid (VPA)respectively. The two indexes went back respectively when supplied with FA.Conclusions Both CBZ and VPA possess mutagenic action, yet nitrazepam does not.FA may help repair the chromosome damage and reduce the mutagenesis effects.

The latest findings of our laboratory showed that Angelica sinensis polysaccharide (ASP) showed a definite effect in regulating the aging of hematopoietic stem cells. Leukemia is a type of malignant hematopoietic tumor in hematopoietic stem cells. There have been no relevant reports about ASP's effect in regulating the aging of leukemia cells. In this study, human acute myeloid leukemia (AML) KG1alpha cell lines in logarithmic growth phase were taken as the study object, and were divided into the ASP group, the cytarabine (Ara-C) group, the ASP + Ara-C group and the control group. The groups were respectively treated with different concentration of ASP, Ara-C and ASP + Ara-C for different periods, with the aim to study the effect of ASP combined with Ara-C in regulating the aging of human acute myeloid leukemia KG1alpha cell lines and its relevant mechanism. The results showed that ASP, Ara-C and ASP + Ara-C could obviously inhibit KG1alpha cell proliferation in vitro, block the cells in G0/G1 phase. The cells showed the aging morphological feature. The percentage of positive stained aging cells was dramatically increased, and could significantly up-regulate the expression of aging-related proteins P16 and RB, which were more obvious in the ASP + Ara-C group. In conclusion, the aging mechanism of KG1alpha cell induced by ASP and Ara-C may be related to the regulation of the expression of aging-related proteins, suggesting that the combined administration of ASP and anticancer drugs plays a better role in the treatment of leukemia .

Objective To evaluate the cardiopulmonary exercise capacity in patients with essential hypertension (EH) complicating with or without left ventricular hypertrophy (LVH). Methods Graded maximal exercise test on the bicycle ergometer with respiratory gas analysis were performed in 30 gender and age matched normotensive controls, 40 EH patients without LVH and 30 EH patients with LVH (LVMI 125 g/m2 in males and 120 g/m2 in females). Metabolic equivalents (METs), oxygen uptake(VO2), oxygen uptake to body mass ratio (VO2/kg) and oxygen uptake to heart beat ratio (VO2/HR) at time of reaching anaerobic threshold (AT) and at maximal oxygen uptake (VO2max) were measured and compared. Results METs and VO2/kg were significantly reduced in EH patients with or without LVH compared with controls [ at AT, METs: 3.57±0. 8 and 4. 34±1.47 vs. 5.21±1.45 ; VO2/kg: 12. 38± 2. 85 and 14. 42±4. 33 vs. 18.48±4. 52, all P < 0. 01 ;at VO2max, METs:4.94±1.24 and 5. 90±1.51 vs. 6.96±1.85;VO2/kg:(17.20±4.34) ml·min-1·kg-1and (20.41±4.59 )ml · min-1·kg-1 vs. (24. 04±5.21) ml·min-1·kg-1, all P < 0. 01 ]. METs and VO2/kg at both time points were also significantly reduced in EH patients with LVH compared EH patients without LVH ( all P < 0. 05). The lower VO2/kg in hypertensive patients was significantly correlated to higher LVMI ( P < 0. 05 ). Conclusions Cardiopulmonary exercise capacity was reduced in hypertensive patients, especially in hypertensive patients with LVH.

OBJECTIVE: To probe into the role of liposomal prostaglandin E(1) (Lipo-PGE(1)) on reperfusion injury in a rabbit ischemia-reperfusion model. METHODS: Twenty-four open-chest rebbits were randomized to receive a 10 min intravenous infusion of either liposome diluent, free PGE(1), or Lipo-PGE(1) after 60 min of left anterior desending (LAD) ligation just before reperfusion. Serum creatine phosphokinase (CPK), malodialdehyde (MDA), superoxide dismutase (SOD) were detected; infarct size and region at risk were measured. RESULTS: Infarct size as a ratio of weight of infarcted tissue to weight at risk (MI/RISK) was significantly reduced with Lipo-PGE(1) (32.20+/-4.70)% compared with PGE(1) (42.09+/-6.93)% or placebo (44.57+/-5.46)% infusion (P<0.01). The values of serum CPK, MDA during reperfusion in treatment of Lipo-PGE(1) group were significantly reduced than in treatment of PGE(1) group or control group (P<0.05), and the values of serum SOD were significantly increased (P<0.05). CONCLUSION: Lipo-PGE(1) can effectively decrease the serum CPK and MDA contents, elevate the SOD activity, and attenuate myocardial reperfusion injury.

The efficacy of Chinese herbal formula in treating depression has been proved in many studies. In this study, six different Kaixin San formulas were compared to investigate their effects on central monoamine neurotransmitters of chronic stress rats and against depression based on their different components in plasma, in order to discuss the efficacy-comparability relationship and the possible efficacy mechanism. The classic isolation method and the chronic unpredictable mild stress (CUMS) depression model were combined to investigate the changes in contents in hippocampus and monoamine neurotransmitters (NE, DA, 5-HT) and the components of some formulas in plasma with HPLC and UPLC-Q-TOF-MSE methods. As a result, Dingzhi Xiaowan recorded in Essential Recipes for Emergent Use Worth A Thousand significantly increased the behavioral scores, NE and 5-HT contents in hippocampus and NE, DA and 5-HT contents in cortex, with the best anti-depressant effect. Dingzhi Xiaowan recorded in Complete Records of Ancient and Modern Medical Works showed a notable increase in sucrose preference and open field score in model rats, NE content in hippocampus and NE, DA and 5-HT contents in cortex, with a certain anti anti-depressant effect. Kaixin San recorded in Ishinpo showed remarkable rise in weight of model rats. NE content in hippocampus and DA content in cortex. Puxin Decoction recorded in A Supplement to Recipes Worth A Thousand Gold showed 5-HT content in hippocampus and DA content in cortex. Kaixin San recorded in Yimenfang only showed DA content in cortex. Kaixin Wan recorded in Essential Recipes for Emergent Use Worth A Thousand did not mention the antidepressant effect. According to the results, the formulas' different anti-depressant effects may be related to the different plasma components.
