Objective In this paper,we aimed at discussing the impacts of follow-up nursing on treatment compliance and lung function of patients with chronic obstructive pulmonary disease(COPD)during the rehabilitation period after discharge.Methods COPD patients(68 cases)were divided randomly into the intervention group and the control group with 34 cases in each group.We gave the intervention group follow-up nursins during the ensuing 6 months after discharge to give them guidance on health problems in order to promote the treatment compliance of patients.On the contrary,the control group did not take any follow-up nursing.Six months later,we conducted an evaluation of the tmalment compliance and amelioration of lung function in the t wo groups.Results As a result,six months after discharge,the patients'treatment compliance status and lung-function indicators in the intervention group were significantly better than those of the control group(P＜0.01).Conclusions The follow-up nursingcan promote the COPD patients'treatment compliance status and amelioration of lung function during the rehabilitation period.

Objective To investigate the effects of minocycline,a selective microglia inhibitor on dorsal GABAB receptor expression in the spinal cord in a rat model of neuropathic pain and the possible mechanism.Methods Forty-eight male SD rats weighing 220-260 g were used in this study.Neuropathic pain was induced by ligation of L5 spinal nerve(SNL).The animals were randomly divided into 4 groups(n=12 each):Ⅰ sham operation;Ⅱ SNL;Ⅲ sham operation+intrathecal(IT)minocycline 50 μg;IV SNL+IT minecycline 50 μg.Paw withdrawal threshold to von Frey hair stimulation was measured before operation(baseline)and at post-surgery days 1,2,4,6,8,10,12,14,16,18 in 6 animals in each group.The GABABR2 expression in dorsal horn of spinal cord was detected by Western blot at the time point when paw withdrawal threshold to mechanical stimulation was the lowest in another six animals which did not undergo yon Frey hair stimulation test.Results The paw withdrawal threshold to mechanical stimuli and the GABABR2 expression in the dorsal horn of spinal cord were significantly lower in SNL group than in sham operation group.The decreased paw withdrawal threshold to von Frey hair stimulation and the down-regulated GABABR2 expression in the spinal cord induced by SNL were ameliorated by intrathecal administration of micmglia inhibitor- minocycline in group Ⅳ.Conclusion The mechanism of neuropathic pain mediated by microglia activation may be related to the inhibition of GABAB receptor activation.

Objective To observe the effect of moxibustion on the blood lipid and hemorheology in senile patients with coronary heart disease (CHD) due to heart blood stagnation who underwent interventional treatment.Method A hundred senile CHD patients were randomized into a treatment group and a control group, 50 cases in each group. The control group was intervened by conventional medications, while the treatment group was additionally by thunder-fire moxibustion. The blood lipid and hemorheology were observed before the treatment and after 3 treatment courses.Result The blood lipid parameters (including CHO, TG, HDL-C and LDL-C) were changed significantly in the treatment group after the intervention (P<0.05). The CHO, TG, and LDL-C levels of the treatment group were significantly different from that of the control group (P<0.05). The hemorheology parameters (whole blood viscosities at a high-, middle-, and low-shear rate, and fibrinogen) were significantly changed in the treatment group after the intervention (P<0.05). The whole blood viscosities at a high-, middle-, and low-shear of the treatment group were markedly different from that of the control group (P<0.05).Conclusion Thunder-fire moxibustion can down-regulate the blood lipid and blood viscosity of CHD patients undergone interventional treatment, and thus improve myocardial ischemia.

OBJECTIVEThe Pul-stent is a new cobalt alloys stent, specially licensed for pulmonary artery stenosis. The aim of this study was to investigate the value of the stent implantation as the treatment of postoperative pulmonary artery stenosis.

METHODClinical practice was carried out to evaluate effectiveness, safety and maneuverability of Pul-stent in the defined clinical setting. Transthoracic echocardiography, chest roentgenography and electrocardiography were carried out as follow-up studies at 1 and 3 months after procedures.

RESULTTen patients (7 males and 3 females) received Pul-stent implantation in left or right pulmonary arteries (9 stents in left and 1 stent in right). For 9 cases transcatheter stent implantation was performed and in I case hybrid procedure. The median age was 7. 9 years (range 3. 4 - 13. 7 years). The median weight was 22. 3 kg (range 13 - 32 kg). Among them 6 cases were post surgical repair of tetralogy of Fallot, 2 cases were after Fontan procedures, 1 patient was post surgical repair of pulmonary atresia with ventricular septal defect, and 1 patient had stenosis at Glenn pathway. The pressure gradient at the stenosis decreased from (31. 6 ± 10. 2) mmHg(1 mmHg =0. 133 kPa) to (7. 3 ± 10. 3) mmHg, and the diameter of the narrowest segment increased from (4. 0 ± 2. 3) mm to (9. 6 ± 2. 7) mm, the right ventricle to aortic pressure ratio decreased from 0. 54 to 0. 36, all of these improvements were statistically significant (t = 3. 9, -9. 7, 4. 5; P =0. 008, 0. 000, 0. 004). The total procedure time ranged from 55 to 220 min (median 117 min) , and the fluoroscopy time ranged from 9 to 67 min (median 26 min). There were 2 cases of post-stenting pneumorrhagia. No stent fracture, stent malposition and other severe complications were observed. Initial follow-up of 1 and 3-months showed good results with maintenance of improved caliber of the stented vessel, and the gradient across the stenosis area measured by echocardiography was (32. 0 ± 14. 6) mmHg after 3 months. Compared with before stentifng ((40.6 ± 15. 2) mmHg) and 1 month later ((30. 6 ± 13. 6) mmHg), the difference was not statistically significant (t =2. 2,1. 76; P =0. 07, 0. 10).

CONCLUSIONPul-Stent tracking and delivery was excellent, the initial experience has shown that Pul-stent implantation was effective and safe in treating post-operative branch pulmonary artery stenosis. Further follow-up study should be conducted to make sure whether those good results would be kept constant.

In order to set up a base for stem cells to be widely used in clinical medicine, we tried to optimize, in this study, the technique that induces human mesenchymal stem cells (hMSCs) to differentiate into neural stem cells by using cerebrospinal fluid (CSF) from the different groups. After the induction, presence of neural stem cells was confirmed with microscope observation, flow cytometry analysis, immunohistochemistry and fluorescent immunohistochemistry. At the same time, we also compared and analysed the data of the number of stem cells when it totally met the requirements for clinical treatment and the days required. At last, we confirmed that hMSCs could be induced to differentiate into neural stem cells, and that the number of cells totally met the requirements for clinical treatment. But there were some differences both in the number of cells and the days required. Among the groups, the group that marrow mesenchymal stem cells from patients own induced by CSF from healthy volunteers used the shortest time and the quantity of the cells was significantly higher than those of the others.
