Objective:By analyzing clinical data, discuss the clinical efficacy of balloon dilatation for the treatment of tuberculous scarred airway stenosis and factors affecting efficacy. Methods:Selected 13 cases airway stenosis caused by tracheobronchial tuberculosis.Airway stenosis was confirmed and measured by bronchoscopy and CT before balloon dilation. Balloon dilatation with forming expansion was conducted once a week. We evaluated the shortness of breath scores, measuring FEV1, FVC and the diameter of airway before and after dilation. The long-term outcome and lung function improvement were evaluated. Results:Thirteen cases were treated by balloon dilation with fiberoptic bronchoscopy. The airway diameter before and after the treatment, shortness of breath score, FEV1, FVC have improved significantly, the difference was significant(t=15.596, t=-27.657, t=-14.604, t=-41.766;P<0.05). Conclusion:Balloon dilation treatment for tuberculous scarred airway stenosis can achieve better results.

OBJECTIVE: To observe the effects of Cili juice enriched with SOD (CLJES) on lead excretion, activity of superoxide dismutase (SOD) in erythrocytes, plasma lipid peroxidation (LPO) and immune function in experimental lead poisoning animals. METHODS: Lead poisoning models were made in rats and mice. The effects of CLJES on lead excretion, SOD activity, LPO concentration in rats and immune functions in mice were determined and compared with those of conventional EDTA treatment. RESULTS: CLJES significantly increased lead excretion. Furthermore it significantly increased SOD activity, reduced LPO concentration in rats with lead poisoning and enhanced immune function in lead loaded mice, however EDTA had no such actions. CONCLUSION: CLJES might exert a wider range of therapeutic effects on lead poisoning than EDTA.

Objective:To observe any effect of function-oriented training on the balance of recovering stroke survivors and on their ability in the activities of daily living.Methods:Sixty stroke survivors in recovery were randomly divided into an observation group ( n=30) and a control group ( n=30). The control group received routine rehabilitation training, while the observation group underwent function-oriented training for 6 weeks. Before and after the intervention, both groups were evaluated using the Berg balance scale (BBS), the Fugl-Meyer lower extremity assessment (FMA-L), the timed up-and-go test (TUGT) and the modified Barthel index (MBI). Results:After the treatment, significant improvement was observed in all of the measurements in both groups. The improvements in the average BBS, FMA-L and MBI scores and in the TUGT times of the observation group were significantly better than those of the control group.Conclusion:Function-oriented training can improve the balance and the ability in the activities of daily living of stroke survivors more effectively than the routine therapy.

Objective To investigate the effects and mechanism of deoxypodophyllotoxin on cell proliferation and mi?gration of human lung cancer NCI-H358 cells in vitro. Methods CCK-8 assay, flow cytometry assay, wound healing assay and DCFH-DA assay were used to detect the effects of deoxypodophyllotoxin on the proliferation, cells cycle, apoptosis, mi?gration and reactive oxygen species (ROS). The protein expressions of Cyclin B1, Cdc25c, CDK1, Caspase-3, p53, Bcl-2, MMP9, ERK1/2, p38MAPK and JNK were measured by Western blot assay, respectively. Results Deoxypodophyllotoxin inhibited cell proliferation and reduced migration in human lung cancer NCI-H358 cells. Flow cytometry analysis showed that treatment with deoxypodophyllotoxin resulted in cell cycle G2/M and S phase arrest, cell apoptosis and ROS production. The result of Western blot assay showed that protein expressions of Cyclin B1, Cdc25c, CDK1, Bcl-2 and MMP9 were down-regulated while Caspase-3 and p53 were up-regulated. Moreover, Deoxypodophyllotoxin treatment decreased the phosphory?lated levels of ERK1/2, p38MAPK and JNK obviously. Conclusion Deoxypodophyllotoxin could suppress the proliferation and migration of human lung cancer NCI-H358 cells in vitro, which is a potential anti-tumor drug.

Objective To explore the efficacy of low tidal volume ventilation strategy in children with acute hypoxia respiratory failure (AHRF).Methods A total of 79 hospitalized children with AHRF from Aug 2006 to Jul 2011 in PICU of Kunming Children's Hospital were enrolled in this study.The observation group in-cluded 55 children who received low tidal volume ventilation strategy (6-8 ml /kg),while the other 24 children (control group)were given traditional mechanical ventilation (10-12 ml /kg).Oxygenation situations such as PaO2 ,PaCO2 ,PaO2 /FiO2 ,oxygen index and blood gas pH value,organ function,mechanical ventilation complica-tions,hospitalization days and expenses in PICU and the mortality were observed.Results (1)PaO2 ,PaO2 /FiO2 and oxygen index in the observation group were better than those in control group after 24 h mechanical ventilation [(68.51 ±7.53)mmHg(1 mmHg =0.133 kPa)vs.(61.64 ±9.28)mmHg,(162.9 ±21.84)mmHg vs.(152.1 ± 19.03)mmHg,and 18.85 ±4.1 vs.26.53 ±5.2,respectively],and there were significant differences between two groups (P ﹤0.05);and there were also significant differences between two groups in the results after 48 h and 72 h mechanical ventilation.(2)The PaCO2 was (47.48 ±10.52)mmHg after 24 h in observation group,while the PaCO2 in control group was (30.17 ±6.59)mmHg,and it suggested excessive ventilation.(3)Mechanical venti-lation time (7.6 ±3.1)d and hospitalization days (12.8 ±3.6)d were shorter in observation group(P ﹤0.01). Barotrauma (7.3%)and mortality (20.0%)in observation group was significantly lower than those in control group (29.2%,41.6%;P ﹤0.01).The number of damaged organs in observation group was lower than that in control group (P ﹤0.05).Conclusion Low tidal volume ventilation with appropriate positive end expiratory pressure could improve oxygenation,prevent alveolar collapse,reduce complications and mortality for children with AHRF,it should be applied for the treatment of children with AHRF.

Apoptosis refers to the programmed death process of cells modulated by genes. It plays an important role in promoting the evolution of organisms, regulating the development of multiple systems, and maintaining the stability of internal environment. The major apoptosis pathways include mitochondrial pathways, death receptor pathways, and endoplasmic reticulum pathways. With the rapid development of the scientific research on acupuncture, it’s revealed that cell apoptosis should be closely related to the action of acupuncture. So far, the major apoptosis factors involved in relevant researches are P53, Bcl-2 family, Cyt-C, Caspase, Fas/Fasl, TNFR1/TNF-?, and FADD-Caspase8, and PERK, etc. Via influencing these apoptosis factors or genes, acupuncture can produce various effects in improving tissue ischemia, protecting neural cells, reducing inflammation, and correcting endocrine disorders. This article summarized and reviewed the apoptosis pathways and key factors related to the action of acupuncture, to provide some beneficial references for future studies.

OBJECTIVETo study the function of the chalcone synthese gene introns in Scutellaria baicalensis, and clarify preliminarily their role in abiotic stress.

METHODThe CHS introns with specific primers were cloned and bioinformatic method was applied to predict the cis-elements in the intron of CHS. The introns were subcloned into binary vector, pCAMBIA-1301 before being transferred to tobacco. Then the activity of GUS of the transgenic tobacco seeds was analyzed.

RESULTSeven cis-elements were found in the introns. Under the dark and high temperature GUS expression rose at the first (3 h), but then declined (9 h). ABA and MeJA regulated insignificantly the GUS activity in normal temperature; treatment of 10% PEG induced GUS expression.

CONCLUSIONCHS introns could be play a role in the regulation of S. baicalensis phenylpropanoid biosynthetic pathway.

Objective To study the outcomes of 2 rehabilitation protocols after simultaneous stage Ⅰ bilateral total knee replacement (TKR). Methods One hundred and twenty patients admitted for stage Ⅰ bilateral TKR were assigned randomly to receive alternative or traditional rehabilitation therapy. Rehabilitation training was administered in both alternative and traditional groups before and after operation. In alternative group, each rehabilitation action was designed to be done on one side and the other side alternatively. In traditional group, each training session was designed to be done on one side and then followed by the other side in succession. Visual analogue scale (VAS)scores were evaluated for 2 weeks after operation and deep vein thrombosis (DVT) complications were recorded for 3 months after operation. The range of motion ( ROM), American hospital special surgery (HSS) knee scores and SF-12 scores were recorded at 1 d before operation and the 1st, 3rd, 6th and 12th month after operation, Results One hundred and fifteen patients completed all training sessions and assessments. Compared with traditional group, alter-native group had significantly lower VAS scores in the early postoperation stage and significantly better knee function scores and SF-12 scores at the 1 st and 3rd month postoperation (P <0. 005). Conclusion The alternative protocol can speed up rehabilitation and lead to decrease VAS scores in the early postoperation stage, and improve knee func-tion and physical and mental health after TKR.
