Objective To investigate the curative effects of selected proprioceptive neuromuscular facilitation (PNF) patterns and techniques on shoulder subluxation soon after strokd. Methods Forty-one stroke patients with shoulder subluxation were randomly divided into a treatment group(n=22) and a control group (n=19). The patients in the treatment group receiveed the selected PNF techniques daily for 4 weeks, while the patients in the control group were treated with their previous therapeutic protocol. The shortest distance from the lower border of the acromion to the nearest point of the humeral head(AHH) was measured. Brunnstron grading was used to evaluate motor function in the affected upper linb, and a visual analogue scale (VAS) to assess subLuxation. Shoulder pain before and after treatment was also assessd. Results There was no significant difference in general condition between the patients in the two groups before treatment. In the treatment group, a significant improvement in AHH distance of the affected shoulder was observed after 4 weeks. Shoulder subluxation waw cured in 13 patients, with AHH distance ＜0.75 cm after 4 weeks of treatment. Conclusion The PNF technique applied was effective for the early treatment of subluxation after stroke. Motor function in the affected upper limb could be improved significantly and pain alleviated.

Objective; To evaluate the efficacy of Twin-block appliance in Class Ⅱ division 1 of adolescents. Methods: Several e-lectronic databases (PubMed, The Cochrane library, Embase, CBMdisk, CNKI, VIP)were searched. Abstract that appears to fulfill the initial selection criteria were selected by consensus and original articles were retrieved. Five Chinese journals were hand searched for possible missing articles. Randomized controlled trials(RCTs) that evaluate the efficacy of Twin-block appliance in Class Ⅱ division I adolescents without any surgical intervention or syndromic characteristics were considered. A comparable untreated control group was required to factor out normal growth changes. The quality of included studies was evaluated according to Cochrane Reviewers Handbook 4.2.6 Meta-analysis was performed by using RevMan 5.0.0 software. Results: Four RCTs including 289 patients were identified. The results of our meta-analysis showed a significant increase on SNB angle, Ar-Gn, Nasolabial angle and Labial-mental fold compared with control group(P<0.05). Whereas overjet, overbite, ANB angle and Ls-E had a significant decrease. In addition, SNA angle and Li-E didnt show statistical significant changes(P>0. 05). Conclusion; In Class II division 1 of adolescents, Twin-block appliance can effectively decrease their overjet, overbite, ANB angle, and induce anterior-posterior growth of mandible. The effect on restrain forward growth of the maxilla was unclear. More RCTs are required to evaluate the efficacy of Twin-block appliance.

Objective To investigate the protective effect of c-jun N-terminal kinase (JNK)inhibitor SP600125 against acute liver failure in mice.Methods Fifty-five male C57/BL6 mice were divided into control group (n =30) and SP600125 group (n =25).The animals were given an intraperitoneal injection of D-galactosamine (D-GalN,400 mg/kg body weight)/lipopolysaccharide (LPS,30 μg/kg body weight).The control group and SP600125 group were given 10％ dimethyl sulfoxide (15 mL/kg body weight) or SP600125 (75 mg/kg body weight) subcutaneously 12 h and 1 h before D-GalN/LPS administration,respectively.D GalN/LPS induced mouse JNK activation was detected by immunohistochemistry for phospho JNK (p-JNK).D-GalN/LPS induced mouse liver cell apoptosis was detected by immunohistochemistry for Caspase-3 and TdT-mediated-dUTP nick endlabeling (TUNEL).Serum alanine transaminase (ALT) level was tested to assess liver injury.Survival rate of mice within 24 h after D-GalN/LPS administration was observed.The comparison between groups was done by t test and survival rate was analyzed by Kaplan-Meier method.Results JNK activity in liver tissues,as indicated by observation of p-JNK positive cells by immunohistochemistry,was diminished 4 h after D-GalN/LPS administration in SP600125 group.Reduced Caspase-3 activity was observed 6 h after D-GalN/LPS administration in SP600125 group (as indicated in immunohistochemistry by Caspase-3 positive cells).Mice in SP600125 group showed significantly lower TUNEL-positive cell count than control group (43.0±24.5 vs 194.7±73.8; t=9.743,P=0.000).Serum ALT level 6 h after D-GalN/LPS administration was (24.0±54.7) U/L in SP600125 group,which was significantly lower than that in control group [(1234.4±478.4) U/L; t=4.734,P=0.0015].SP600125 also significantly improved the survival rate within 24 h after D-GalN/LPS administration (4/5 vs 1/10； x2=5.225,P=0.0223).Conclusions JNK inhibitor SP600125 exerts protective effects against D-GalN/LPS induced acute liver failure in mice by suppressing JNK activation and hepatocyte apoptosis.

Objective To observe the improvement of postoperative pulmonary function and oxygen partial pressure during general anesthesia for open abdominal surgery with lung protective ventilation strategies and alveolar recruitment maneuvers. Methods Seventy patients who underwent selective open abdominal surgery were selected, and they were divided into standard ventilation group (tidal volume 8 ml/kg) and protective ventilation group (tidal volume 6 ml/kg, 5 cmH2O positive end-expiratory pressure, and alveolar recruitment maneuvers, 1 cmH2O=0.098 kPa) according to the random digits table method with 35 cases each. The airway pressure, blood pressure, pulse oxygen saturation (SpO2), end-tidal partial pressure of carbon dioxide (PETCO2) and adverse reactions were observed. The SpO2, partial pressure of O2 (PaO2) and pulmonary function before surgery and 1, 3, 5 d after surgery were measured. Results The respiratory rate, airway pressure and PETCO2 levels in protective ventilation group were significantly higher than those in standard ventilation group: (12.3 ± 2.1) times/min vs. (10.2 ± 1.0) times/min, (15.1 ± 2.8) cmH2O vs. (13.5 ± 2.3) cmH2O, (34.6 ± 2.1) mmHg (1 mmHg=0.133 kPa) vs. (32.1 ± 1.4) mmHg, and there were statistical differences (P<0.05). The SpO2 in 2 groups was maintained at 0.99. There was no statistical difference in the incidence of postoperative complications between 2 groups (P>0.05). The SpO2 and PaO2 levels at 1, 3 d after surgery in protective ventilation group were significantly higher than those in standard ventilation group:0.951 ± 0.018 vs. 0.936 ± 0.016 and 0.964 ± 0.018 vs. 0.949 ± 0.018, (74.8 ± 6.8) mmHg vs. (65.0 ± 6.2) mmHg and (79.6 ± 6.0) mmHg vs. (70.6 ± 5.3) mmHg, and there were statistical differences (P<0.05). The forced expiratory volume in 1 s (FEV1), percentage of the estimated value of FEV1, forced vital capacity (FVC) and percentage of the estimated value of FVC at 1, 3 and 5 d after surgery in protective ventilation group were significantly higher than those in standard ventilation group, the FEV1/FVC at 1 d after surgery was significantly higher than that in standard ventilation group, and there were statistical differences (P<0.05). Conclusions The lung protective ventilation strategy and alveolar recruitment maneuvers can improve the postoperative pulmonary function and oxygen partial pressure during general anesthesia for abdominal surgery. Low vital volume, appropriate positive end-expiratory pressure and recruitment maneuvers can protect the lung in general anesthesia patients.

Objective: To observe the influence of left-thoracic radiotherapy on heart function and quality of life in patients with breast cancer after breast-conserving surgery. Methods: A total of 35 patients with breast cancer, who recently received breast-conserving surgery and left-thoracic radiotherapy, were continuously selected as radiotherapy group. They received routine echocardiography (ECG), tissue Doppler imaging (TDI) and evaluation of Chinese questionnaire of quality of life in patients with cardiovascular diseases (CQQC) before and after radiotherapy. The results were compared with those of 31 patients (control group), who received radical mastectomy without breast radiotherapy in the same period. Results: There were no significant difference in left heart function indexes by ECG and TDI, all dimensional and total scores of CQQC between two groups before radiotherapy (P>0.05 all). After five-week treatment, compared with evaluation before radiotherapy and control group after treatment, there were significant decrease in E [(0.90±0.32) cm/s vs. (0.90±0.38) cm/s vs. (0.86±0.29) cm/s], E/A [(1.28±0.46) vs. (1.28±0.45) vs. (1.20±0.38)], Em [(10.12±1.93) cm/s vs. (9.95±1.64) cm/s vs. (7.51±1.12) cm/s], Em/Am [(1.25±0.26) vs. (1.24±0.23) vs. (0.90±0.15)] （P<0.05 all）, all dimensional scores （P<0.05～<0.01）and total score [(67.36±7.87) scores vs. (63.75±7.26) scores vs. (52.83±6.40) scores] （P<0.01）of CQQC in radiotherapy group. Conclusion: There are often decrease in left heart function and quality of life in patients with breast cancer undergoing left-thoracic radiotherapy after breast-conserving surgery, so it’s necessary to perform targeted rehabilitative treatment.

In order to find the characteristics of two members of gene family of squaleneexpoxidase (SE) , a quantitative real time PCR method was developed to analyze the expression of Eleutherococcus senticosus SE1 and SE2 gene from different growth periods and in different organs. The result indicated that all the expression of SE2 more than SE1 in the whole growth period and organs of E. senticosus. And in the whole growth period, expression of SE1 showed a low-high-low characteristic. Both expression of SE2 and growth period showed the same trend. The lowest content of the expression was in the roots. SE1 expression have been improved more than SE2 when treated with MeJA. The expression of E. senticosus SE1 and saponins content had significantly positive correlation (P < 0.05) and the correlation coefficients was 0. 858, while the correlation was not significant for SE2. That indicated that SE1 played a key enzyme gene in the biosynthesis of triterpenoidsaponins

In order to study the contraindications of the compatibility of Flos Genkwa-Radix et Rhizoma Glycyrrhizae, in this study, the solubilizing and poisoning essence were explored. In this experiment, chromatographic assay, field emission scanning electron microscopy, MTT cytotoxicity evaluation, and other methods were used to study the main chemical components, morphology and toxicity of the ethyl acetate part of Flos Genkwa and its co-decoction with glycyrrhizic acid, in order to clarify Flos Genkwa-Radix et Rhizoma Glycyrrhizae incompatibility provides a new idea for the research on incompatibility of Flos Genkwa-Radix et Rhizoma Glycyrrhizae. The results showed that after co-decoction of the ethyl acetate part of Flos Genkwa with glycyrrhizic acid, high performance liquid chromatography (HPLC) detected the dissolution of the toxic component yuanhuacine of 54.8%, while yuanhuacine chromatographic peak was not detected in the Flos Genkwa ethyl acetate part of the single decoction. The increase of co-decoction dissolution rate was observed by scanning electron microscopy, and it was found that glycyrrhizic acid uniformly dispersed the fat-soluble components of Flos Genkwa into nano-scale particles, which improved the solubility and stability in the solution. Furthermore, the results of cytotoxicity evaluation showed that the survival rate of cells decreased after co-decoction, 4',6-diamidino-2-phenylindole (DAPI) staining also gave the same results. In summary, the co-decoction of the ethyl acetate part of Flos Genkwa with glycyrrhizic acid promotes the dissolution of the toxic component yuanhuacine, and makes the part form uniformly distributed nanoparticles, which is conducive to the absorption of the ingredient and increases the toxicity.
