Objective To evaluate the recent impact and long-term effects of recombinant human acidic fibroblast growth factor (rh-aFGF) of cesarean section on women's abdominal incision healing.Methods In 516 cases of cesarean section in women,randomly divided into placebo group (172 cases),spray group (172 cases) and flush group (172 cases).The placebo group received 0.9% sodium chloride washing abdominal incision suture.The spray group incision suture direcdy after the administration of rh-aFGF spray,per square meter of 3-4 sprays,3-5 times/d.The flush group was given before 2 rh-aFGF dissolved in 10-20 ml of 0.9% sodium chloride directly after washing the incision suture,then given spray treatment.The recent follow-up of 15 d observed maternal abdominal incision healing.Long term follow-up of 3 months to observe the incision scar formation.Results The abdominal incision heating time was (8.6 ±3.5) d,that was obviously shorter than that in spray group (10.4 ±3.7) d and placebo group (12.7 ± 4.9) d (P < 0.05).The delay healing accounted for 4.2% (7/166) in flush group,significantly lower than that in placebo group (34/168,20.2%) and spray group (16/165,9.7%) (P< 0.05).There was no significant difference in the incidence of fat liquefaction,postoperative infection among three groups (P > 0.05).Flush group exudation,abdominal wall adhesions was lower than placebo group and spray group [2.4%(4/166) vs.10.1%(17/168),5.5%(9/165),3.6%(6/166) vs.17.3%(29/168),9.7%(16/165)](P<0.05).Long term follow-up,flush group scar area than spray group reduced by 13.5%,than placebo group reduced by 27.2%.Conclusions A recent rh-aFGF can reduce the cesarean section abdominal incision healing time and reduce abdominal wall adhesions and exudation;rh-aFGF the best dosage is intraoperative irrigation treatment spray combined with postoperative.

Objective To investigate the effect of Niaochangshu capsule on urodynamics in bladder filling period of patients with post-menopause urethral syndrome of renal deficiency and blood stasis type.Methods A total of 36 patients with post-menopause urethral syndrome of renal deficiency and blood stasis type were randomly assigned to two groups:the trial group(24 patients were treated with Niaochangshu capsule) and the control group(12 patients were treated with Nilestriol).All patients were treated for 8 weeks.The changes of the urodynamic indexes in bladder filling period(the capacity of the bladder,the compliance of the bladder and the sensitivity of the bladder) were compared between the two groups.Results After treatment,the urodynamic index,including the maximum cystic capacity,the volume at the first desire to void and the cystic compliance were evidently improved in both of the trial group and the control group(P0.05).Conclusion Niaochangshu capsule is effective in treating the patients with post-menopause urethral syndrome of renal deficiency and blood stasis type.It can increase the cystic capacity and compliance,step down the sensitivity of the bladder.Its effect is similar to Nilestriol.

An evaluation scale of medical services quality was developed on the basis of "patients' experience". The questionnaires were developed by, among others, searching relevant literature, collecting well-established assessment scales, measuring patients' experience and satisfaction, brain-storming, literature analysis. Delphi method was adopted for expert consultation. Scale items were screened and revised. The key indexes were converted. Field surveys were conducted for testing the reliability and validity of the scale. Our modified evaluation scale for measuring medical services quality based on "patients' experience" included 6 dimensions (tangibility, reliability, responsiveness, assurance, empathy and continuity), and 50 items. The novel scale based on "patients' experience" may better serve the purpose of assessing medical services quality.
5.Progress in structure and CO2-concentrating mechanism of carboxysomes.
Chinese Journal of Biotechnology 2014;30(8):1164-1171
Carboxysomes are extremely efficient microcompartments committed to CO2 fixation due to tailored CO2-concentrating mechanism (CCM). In cyanobacteria and some chemoautotrophs, carboxysomes as organelle-like microbodies encapsulate ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) and carbonic anhydrase (CA). Together with active inorganic carbon uptake transporters, carboxysomes accumulate HCO3(-) in the cytoplasm, leading to high efficiency of carbon fixation. Based on the elucidation of structures and functionalities, heterologous production of carboxysomes has been achieved so far. In fact, the genes encoding either vacant carboxysome shell or only interior components have been characterized. This review summarizes the discovery along with types, showcases molecular structures and roles of carboxysomes in CCM, and presents their broad applications in metabolic engineering.

7.A clinical observation of heart rate turbulence of diabetes
Chinese Journal of Diabetes 2009;17(12):933-934
Objective To discuss the significance and alteration of heart rate turbulence (HRT) of diabetics with ventricular premature beats of coronary heart disease (CHD). Methods 107 patients were chosen and divided into DM group(n=30), CHD group (n=32)and normal group(n=45).The turbulence onset(TO)and turbulence slope(TS) were calculated and analyzed. Results For the diabetics with ventricular premature beats, TO value was higher and TS value was lower than the normal group(all P<0.05).The value of TO and TS of the diabetics with ventricular premature beats were similar to those of CHD(P>0.05). Conclusions HRT can be used to estimate the integrality and stability of cardiac autonomic nerve function for the diabetics and it is an important factor for diagnosis.
8.Establishing a tibia-femoral joint finite element model according to MRI image
Chinese Journal of Tissue Engineering Research 2009;13(39):7623-7626
Images corresponded to the right knee of a 27 years old, healthy, male volunteer, weighing 68 Kg, 175 cm height, with no knee joint disease, were selected. The scanning was performed using 1.5T Twinspeed/Excite magnetic resonance tomography. The image was uninterrupted sagittal planes picture, and the scanning way was from the inside to out. The three-dimensional tibia-femoral joint model was established by the MR1 images after they were handled by correlation analysis software (Mimics10.0, Geomagic Studio 8.0). At last, transformed the model format STL file to IGS file, which can be acceptable by analysis software 11.0. On the base of this way, a highly simulation tibia-femoral model was established. It provides a guarantee for the further finite element analysis concerning checking the surface of femoral condyle cartilage to repair interphalangeal joint injuries. The result demonstrated that 3-D computer model established by using 2-D MRI pictures makes up the CT scanning deficiencies on soft tissue, which confirms the model closer to the real anatomical structure.
9.CT-guided interstitial implantation of ~(125)I seeds for non-small cell lung cancer
Journal of Interventional Radiology 2009;18(9):704-707
Objective To discuss the technique, therapeutic effect and complications of CT-guided interstitial implantation of ~(125)I seeds for the treatment of non-small cell lung carcinoma (NSCLC). Methods With the help of treatment planning system, CT-guided interstitial implantation of ~(125)I seeds was performed in 21 patients with pathologically-proved NSCLC. Multi-plane implanting technique was adopted and ~(125)I seeds of (0.5 -0.8) mCi were placed at intervals of (1.0-1.5) cm. Checkup CT scan was carried out immediately after the procedure to make sure that the seeds were satisfactorily distributed. Follow-up CT scanning was made (2-6) months after the treatment to survey the distribution of the seeds within the tumor. The curative effect and complications were also evaluated and observed. The patients were followed for 12 months. Results Of 21 cases, complete remission was seen in 7, obvious remission in 12 and partial remission in 2. The one year survival rate was 90.5% (19/21). Complications included pneumothorax (n = 6) and hemoptysis (n = 2). No serious complications or treatment-related radiation injuries occurred. Conclusion CT-guided interstitial implantation of ~(125)I seeds is a safe and effective treatment for NSCLC with reliable short-term therapeutic effect.
