ObjectiveTo summarize the application of pressure support ventilation (PSV) on cervical spinal cord injured patients with respiratory dysfunction.MethodSixteen patients were studied.Respiratory rate (RR),tidal volume (VT), minute ventilation (VE),peak inspiration pressure (PIP), dynamic lung conpliance (Cdyn), blood pH value, PaO2 and PaCO2 were measured under the different pressure levels of PSV. ResultAll parameters correlated with the level of PSV. Conclusion Appropriate PSV levels can make the respiratory parameters close to the reasonable level and respiratory functional status for the cervical cord injured patients with respiratory dysfunction.

ObjectiveTo observe the difference between pressure support ventilation(PSV) and synchronized intermittent mandatory ventilation(SIMV) in cervical spinal cord injury patients with respiratory failure.MethodsThe blood gas analysis,respiratory rate,heart rate,blood pressure and subjective feelings were observed in the same patient under different ventilation(PSV or SIMV).ResultsThere was no significant difference in blood pressure when patients underwent PSV and SIMV.Otherwise,There was significant difference in respiratory rate,heart rate,pH,PaO2,PaCO2 and subjective feelings when patients underwent PSV and SIMV,which showed that of PSV were better.ConclusionThe effect of PSV was better than that of SIMV on respiratory failure after cervical spinal cord injury.

Objective To establish an in vitro cell co-culture model that simulates the transplantation environment in vivo ,and to investigate the effect of primary cells from neonatal cortex on the differentiation of PC12 cells. Methods PC12 cells were transfected with pEGFP-N1 vector to express green fluorescent protein (GFP) stably,then these cells were transplanted into primary neurons and glial cells from neonatal cortex. Cultures with PC12 cells alone constituted the control group. Nerve growth factor (NGF) was added into all the other cultures to induce neuronal differentiation of the PC12 cells. Neurite outgrowth of the neuronal PC12 cells was observed with laser confocal microscopy. Results Comparing with the control group,the PC12 cells co-cultured with primary neurons and glial cells showed higher differentiation rate (57.13% to 67.77%,P

Background and purpose: Docetaxel/cisplatin are widely used in chemo-naive patients with advanced non-small cell lung cancer(NSCLC),but the standard 3-weeks'project of docetaxel caused significant toxicity.We performed this study to compare the effect and toxicity of modified and standard 3-weeks'docetaxel/cisplatin as first line chemotherapy for advanced NSCLC.Methods:68 patients with stage ⅢB or Ⅳ NSCLC(proven by histology or cytology) were randomly divided into two groups,modified(A) and standard(B) chemotherapy.Group A: docetaxel 75 mg/m2,divided into 2 days,ivgtt d1 and d 8,cisplatin 25 mg/(m2?d),ivgtt d 1-d 3,q3w;Group B: docetaxel 75 mg/m2,ivgtt d 1,cisplatin was administered as Group A,q3w.The effect and toxicity were assessed after two cycles and one-year survival was followed up.Results:There was no CR in both groups.10 PR,20 SD,4 PD were found in group A,the overall response rate is 29%;whereas 11 PR,20 SD,3 PD were found in group B,the overall response rate is 32%.The one-year survival rate were 38% and 35% in group A and B,respectively.There were no significant difference about the overall response rate(P=0.793) and one-year survival rate(P=0.801) between group A and B.The rates of grade Ⅲ/Ⅳ neutropenia were 18% and 47% in group A and B respectively.The difference was statistically significant(P=0.010).Conclusions:In comparison with the standard 3-weeks'docetaxel/ cisplatin chemotherapy,the modified one has similar response rate but lower hematologic toxicity,and thus it was well tolerated.

Objective:To observe the dynamic changes in serum gastroanteric hormones in patients with stroke complicating stress upper gastrointestinal hemorrhage in acute stage,the changes in acidity,and the changes in gastric empty and to investigate the pathogenetic link of stress pathological change of gastric mucous membrane in patients with stroke(Zhongzangfu,ZZF,中脏腑).Methods:In 20 cases with acute ZZF (Glasgow coma score 6-12 scores) who were all complicating upper gastroenteric bleeding within 24 hours of attack,the levels of motilin(MTL),somatostation(SS),and gastruins(GAS) were measured by radioimmunoassay at the first day (within 24 hours) and the fourth day (within 72-96 hours) respectively meanwhile the gastratube was plased and kept within 24 hours of attack to dynamically observe the pH of gastric juice and the condition of gastric emptying.Results:In comparison with control group the MTL level was significantly increased in patients at the first day of attack (P<0.05),the SS level significantly decreased (P<0.01),and the GSA level had not significant difference (P>0.05).Otherwise the pH (2.87±0.90） of gastric juice in comparison with control group has not significant difference (P>0.05).Among patients in 17 cases the gastric emptying time was prolonged.Even at the fourth day in patients the MTL level was still significantly increased (P<0.01),SS level decreased (P<0.05),and GAS level increased (P<0.01).Conclusions:The upper gastrointestinal hemorrhage in patients with acute ZZF is tightly associated with the changes in MTL and SS but the changes in GAS and gastric pH are not main factor.

Objective:To observe the effects of a preparation of chinese traditional medicine Zengshengping (ZSP) in the treatment of oral lichen planus (OLP).Methods:200 patients with OLP were randomly divided into 2 groups with 100 in each.The patients in one group were treated with ZSP and those in another with levomisolum.The patients were followed up for two years.Results:The total effective rate in ZSP or levomisolum treated group were 90% and 62% respectively (P<0.025).Conclusion:ZSP is more effective in the treatment of OLP than levomisolum.

Objective To explore the clinical effects of injecting methotrexate with hysteroscopic tubal can-nulation combined with Huayu shapei prescription in the treatment of salpingocyesis.Methods 82 unruptured salpin-gocyesis patients were randomly divided into the two groups.41 patients in the observation group were treated by hyst-eroscopic tubal cannulation injection of methotrexate combined with Huayu shapei prescription,41 patients in the con-trol group were treated by methotrexate intramuscular injection with oral mifepristone.The clinical efficacy of the two groups were observed,the level of serumβHCG required for tubal pregnancy,the mass absorption and after treatment of tubal patency.Results Compared with the control group,the difference was significant of the decline of serum βHCG in the treatment group (t=2.67,P<0.05).Compared with the control group,the treatment effectiveness and the absorption of the mass in fallopian tube in the treatment group,the difference was significant (t =3.57,P<0.05 ).Tubal patency detected treated group was superior compared with the control group,the difference was signifi-cant(χ2 =100.23,P<0.05).Conclusion Compared with traditional treatments,injecting methotrexate with hyste-roscopic tubal cannulation combined with Huayu shapei prescription in the treatment of salpingocyesis can effectively reduce the HCG levels,promote the absorption and softening of the ectopic pregnancy mass,to achieve the purpose of killing embryos eliminate micro,it will help to improve patients with clinical symptoms and signs,to maximize the recovery of the patient's reproductive function and physical health.

In order to understand the cost of cancer in rural area, to evaluate the cost burden, the project content and treatment status. Typical sampling and random sampling survey are combined to investigate and account major expenditure and economic loss of cancer treatment and related items, analyzes its rationality and scientific, provide references for improving the level of cancer prevention and treatment.

In order to reduce heavy burden of cancer on patients, families and social, it needs to raise special funds, apply regular screening for 45~65 years old group, achieve early detection and treatment of cancer, reduce medical expenses and economic loss of cancer greatly, reduce mental burden, establish the cancer prevention input-output model, calculates the economic benefits up to 1:9.89. It is proposed to establish the organization, improve the mechanism, expand the overall costs, secure the screening and popularize early detection and treatment.
