ObjectiveTo evaluate the effect of Yuxingchangzhi Decoction on level of norepinephrine (NE) and 5-hydroxyptamin (5-HT) in serum of patients with post-stroke depression. Methods76 patients with post-stroke depression were treated with Yuxingchangzhi Decoction or placebo for 4 weeks. Before and after treatment, all the patients were evaluated with the Hamilton Rating Scale for Depression (HAMD),while the level of NE and 5-HT in serum of patients were measured.ResultsThe total score of HAMD of the patients of Yuxingchangzhi Decoction group was significantly different before and after treatment (P<0.01),while that of the placebo group was not significantly different (P>0.05). The NE and 5-HT level in serum of patients of the Yuxingchangzhi Decoction group were significantly different before and after treatment (P<0.01),but that of the placebo group was not significantly different (P>0.05). ConclusionYuxingchangzhi decoction can raise NE,5-HT level in patients with post-stroke depression and alleviate symptoms of depression significantly.

This study investigated the protective effect of ATP on skeletal muscle satellite cells damaged by H2O2 in neonatal rats and the possible mechanism. The skeletal muscle satellite cells were randomly divided into four groups: normal group, model group (cells treated with 0.1 mmol/L H2O2 for 50 s), protection group (cells treated with 16, 8, 4, 2, 1, 0.5, or 0.25 mmol/L ATP for 24 h, and then with 0.1 mmol/L H2O2 for 50 s), proliferation group (cells treated with 16, 8, 4, 2, 1, 0.5, or 0.25 mmol/L ATP for 24 h). MTT assay, FITC+PI+DAPI fluorescent staining, Giemsa staining and immunofluorescence were performed to examine cell viability and apoptosis, and apoptosis-related proteins. The results showed that the survival rate of skeletal muscle satellite cells was decreased and the apoptosis rate was increased after H2O2 treatment (P<0.01). Different doses of ATP had different effects on skeletal muscle satellite cells damaged by H2O2: the survival rate of muscle satellite cells treated with ATP at 4, 2, or 1 mmol/L was increased. The protective effect was most profound on cells treated with 2 mmol/L ATP. Immunofluorescence showed that ATP could increase the number of Bcl-2-positive cells (P<0.01) and decrease the number of the Bax-positive cells (P<0.01). It was concluded that ATP could protect skeletal muscle satellite cells against H2O2 damage in neonatal rats, which may be attributed to the up-regulation of the expression of Bcl-2 and down-regulation of Bax, resulting in the suppression of apoptosis.

Objective To discuss the set-up isocenter error based on kilovolt cone beam computed tomography (KVCBCT) and to investigate dose deviation led to set-up isocenter error. Methods 21 cases of nasopharyngeal carcinoma ( NPC ) treated with image guided intensity modulated radiotherapy (IG-IMRT)were investigated. The online KVCBCT scan, rigid image registration, set-up error was gained for 376 sets before radiotherapy. We sampled ten and fifteen setup isocenter error in the 376 sets randomly. Without changing beam angle,fields size and leaf sequences and dose weight et al. , we only replaced new isocenter and accumulated the new plan for ten or fifteen plans. We compared the percentage deviation between ten,fifteen times accumulated plans and normal ten , fifteen times plans. Results All 376 sets of KVCBCT image were analyzed for 21 cases. Under the condition of non-correction, the setup isocenter errors are 0. 75mm ± 1.13 mm, 0. 92 mm ±2. 15 mm,0. 82 mm ± 1.24 mm in left-right, superior-inferior and anteriorposterior directions respectively. So, we developed the margins which were 4 mm,6 mm、4 mm in three directions respectively from clinical tumor volume to planning tumor volume (PTV) calculated by two parameters model. In the fifteen accumulated plan, the deviation in the dose of 95% PTV (D95) was -7. 5% - - 11.9%, and the deviation in the D50 was -5. 1% - -8. 2%. Conclusions It is possible of small effects to normal organs and targets because of small error of patient displacement in one fraction.However, many small errors can led to considerable dose difference in targets and normal tissue in thirty fractions of all treatments period. So, according to two parameters model, PTV margin can be designed new planning and depended on IG-IMRT technique, which it will be significantly reduced these dose differences.

Objective To determine the planning target volume margins of head and neck cancers treated by image guided radiotherapy (IGRT).Methods 464 sets cone beam computed tomography (CBCT) images before setup correction and 126 sets CBCT images after correction were obtained from 51 head and neck cancer patients treated by IGRT in our department.The systematic and random errors were evaluated by either online or offline correction through registering the CBCT images to the planning CT.The data was divided into 3 groups according to the online correction times.Results The isocenter shift were 0.37 mm±2.37 mm, -0.43 mm±2.30 mm and 0.47 mm±2.65 mm in right-left (RL), anterior-posterior (AP) and superior-inferior (SI) directions respectively before correction, and it reduced to 0.08 mm±0.68 mm, -0.03 mm±0.74 mm and 0.03 mm±0.80 mm when evaluated by 126 sets corrected CBCT images.The planning target volume (PTV) margin from clinical target volume (CTV) before correction were:6.41 mm,6.15 mm and 7.10 mm based on two parameter model, and it reduced to 1.78 mm,1.80 mm and 1.97 mm after correction.The PTV margins were 3.8 mm,3.8 mm,4.0 mm;4.0 mm,4.0 mm,5.0 mm and 5.4 mm,5.2 mm,6.1 mm in RL, AP and SI respectively when online-correction times were more than 15 times, 11-15 times,5-10 times.Conclusions CBCT-based on online correction reduce the PTV margin for head and neck cancers treated by IGRT and ensure more precise dose delivery and less normal tissue complications.

To analyze the composition regularity of Carthami Flos-containing prescriptions of the Drug Standards of Ministry of Health of People's Republic of China-Traditional Chinese Medicine Preparations (the ministerial standards for Traditional Chinese Medicine) based on the traditional Chinese medicine inheritance support system (TCMISS, RZDZ No. 0389952). Efforts were made to identify 331 prescriptions containing Carthami Flos and summarize 16 attending functions and 10 commonly used drug combinations. Three commonly used drug combinations were selected for an in-depth analysis on Carthami Flos's combined administration regularity. Based on Carthami Flos's attending functions, its effects in paralysis, traumatic injuries and dysmenorrheal were compared to analyze Carthami Flos's core drug combinations for treating different diseases. The regularity of clinical administration and the characteristics of commonly used drug combinations were summarized to provide reference for Carthami Flos's clinical application and new ideas for new drug R&D. Carthami Flos prescriptions was mainly used to treat blood stasis and pain and mostly combined with drugs that could activate blood, promote the circulation of qi and dispel pathogenic wind to treat Qi-stagnation and blood stasis caused by various pathogenic factors such as wind, cold and dampness.

Objective To explore the clinical significance of the brain natriuretic peptide(BNP) in evaluating the cardiotoxicity caused by daunorubicin(DNR) through studying the changes of the plasma BNP levels in children with acute leukemia who accepted the chemotherapy with DNR.Methods Thirty-one children with acute lymphoblastic leukemia(ALL) admitted in the year of 2002-2004 underwent the chemotherapy in DVLP project.The plasma level of BNP was measured by enzyme linked immunosorbent assay(ELISA) and the left ventricular end diastolic diameter(LVEDD) by color Doppler respectively before and after the administration of DNR.Simultaneously,electrocardiography(ECG) and cardiac muscle enzymes(LDH1,CK-MB) were measured as routine.Results The plasma level of BNP increased from(3.97?2.41) ng/L to(18.25?7.63) ng/L(P

20(Z= -2.117, P=0.034), and between the patients with OD and without OD (Z=-3.089, P=0.002), but PCT was not so between the non-surviror and survivor (Z=-1.307, P=0.191). The serum PCT level correlated with the incidence of organ dysfunction (x~2=14.82, P=0.033) and APACHEII (x~2=12.83, P

Objective To study the changes of serum level of high mobility group box-1(HMGB- 1)in patients with multiple trauma in order to forecast organ dysfunction(OD)and deaths.Methods The optical densities of HMGB-1 in serum of 35 patients with multiple trauma were determined on 1st,3rd, and 7th days after trauma,and the incidence of organ dysfunction and deaths were evaluated,then analyzed statistically to learn the relation between the serum levels of HMGB-1 and deaths with an attempt of predic- ting the incident of organ dysfunction and deaths.Results (1)As OD was concerned,there was a statis- tically significant difference in optical density of HMGB-1 on 1st and 3rd days between the two groups of multiple injury patients(t=4.411,P

Objective To explore the change of dietary intake and nutritional status before and after hematopoietic stem cell transplantation (HSCT) in pediatric patients to assess the importance of nutritional interventions.Methods In this observational cohort study,65 children undergoing HSCT between January 2012 and November 2012 in the Department of Hematology and Oncology,Shanghai Children's Medical Center were enrolled.The data collected before preconditioning were considered as the baseline data.We also collected data twice a week between preconditioning and 30 days after HSCT,and once a week from 30 days to 100 days after HSCT.Dietary analysis and urea nitrogen analysis were conducted in parallel.Results The baseline level of energy intake was (5 844.9 ±2 490.4) kJ/d,protein intake was (56.4 ±28.6) g/d,fat intake was (49.7 ±38.9) g/d,and carbohydrate intake was (190.9 ± 91.1) g/d.With the hematopoietic reconstruction,the oral nutrients intake significantly decreased compared with the baseline levels (all P =0.000).During the recovery period after HSCT,the energy intake showed no significant difference when compared with the baseline level in the 6th postoperative week,protein in the 13th week,carbohydrate in the 4th week,and fat in the 6th week.The urine nitrogen was (3.9 ± 2.4) g/d before HSCT,which increased to (16.7 ± 11.0) g/d after preconditioning (P=0.000).In the 1st postoperative week,the weight (P =0.000),triceps skin fold thickness (P =0.003),mid-upper arm circumference (P =0.000),serum albumin (P =0.000) and prealbumin (P =0.000) of the patients all significantly decreased compared with the baseline levels.In the 9th postoperative week,the fat-free body weight percentage (P =0.010),muscle percentage (P =0.001) and protein percentage (P =0.000) were significantly lower than the baseline levels,while the body fat percentage was higher than the baseline level (P =0.002).Conclusions Children undergoing HSCT exhibit a marked reduction in nutrient intakes at the early stage of HSCT,which may gradually return normal during the recovery period.This process may be slow,especially for the protein,and therefore may affect the serum protein level in these pediatric patients.Thus,more careful nutrition guidance is necessary during HSCT for pediatric patients,emphasizing oral nutrients intakes,and high protein dietary or formula may be helpful.
