Objective To test the safety and efficacy of using Botulinum Toxin Type A(BTX-A)in the treatment of chronic daily headache(CDH). Methods Thirty-eight patients in the treatment group injected BTX-A 50 U at 10 positions at the muscles including frontalis, temporalis, splenius capitis and occipitalis. Forty-four patients in the control group were given 2% lidocaine 3 ml plus prednisolone acetate 75 mg(2 ml)at the same muscles sites as in the treatment group. Frequency of headache, headache intensity(evaluated by visual analogue scale, VAS), quality of life(by WHO Qol-8 questionnaire)and adverse reactions were assessed on 0, 30, 60, 90 days after the treatment. Results At follow-up of 30,60, 90 days, the number of headache days per month reduced in both groups. BTX-A group had 14. 0 ±7.8, 13. 0 ±6. 8 and 13.0 ±6. 4 days per month, while the control group had 19. 0 ±6. 1, 21.0 ±6. 1 and 21.0 ±5.8, days at the follow-up of 30, 60 and 90 days, respectively, showing significant difference in the two groups(Z = 2. 895, 4. 544 and 4. 878, all P ＜ 0. 01). At 30 days, VAS scores in the treatment and control groups were 3.6 ± 1.5 and 3. 8 ± 1.3 respectively, showing no significant difference(Z = 1. 254,P =0. 210); At 60 days and 90 days, VAS scores in the BTX-A group were 3.2 ± 1.5 and 3. 1 ± 1.6 respectively, and in the control group were 4. 7 ± 1.3 and 5.0 ± 1.5 respectively, showing significant difference(Z =4. 950 and 5. 096, both P =0. 000). Quality of life in the two groups was slightly improved.After the treatment, 1 case(2. 6%)in BTX-A group occurred brow ptosis. The other patients didn't report any treatment related adverse events. Conclusion BTX-A is an effective and relative safe treatment in patients with CDH.

Objective To develop a new visual feedback postural adjusting ability assessing system, and to study its application value. Methods Pressure sensor was used to determine the changes of the body weight center by tracing the pressure variation of the soles and heels, then eight target points in different directions were added into the software interface to enable the subject move his body weight center to the target point intentionally, finally the system was evaluated by loading on back.Results Program design was performed for the testing system. It's proved that posture adjusting ability might decrease with 20% load on back or the body leaning backwards. Conclusion The newly developed visual feedback postural adjusting ability testing system can be used to research standing balance function.

Objective:To study the effect of comfort care to alleviate postoperative pain of tibial eminence fracture by fixation. Methods:55 patients with tibial eminence fracture between Apr 2013 and Mar 2015 in our hospital were selected and divided into observation group with 26 patients and control group with 29 cases according to the nursing methods. The control group was given the orthopaedic routine nursing method, and the observation group was given the comfortable nursing method to compare two groups of patients with postoperative pain and psychological status before and after the intervention (HAMA anxiety score and HAMD depression scale). Results:There were significant differences between two groups of patients with pain score after the intervention (t=9.545, P<0.05), and HAMA and HAMD scores decline. HAMA and HAMD scores in the observation group were significantly lower than that in the control group (t=11.593, t=10.628;P<0.05). Conclusion:Comfort care can significantly relieve postoperative pain of the tibial condyle spine fractures and improve postoperative anxiety and depression. It has good clinical application value.

Gene therapy has emerged as an efficient modality to treat human diseases.This method is based on the transfer of genetic material to tissues to induce a curative effect.Gene therapy vectors are molecular constructs used to facilitate the penetration of genomic sequences inside the cells.Viral vectots have however several limitations when administered directly to the patient.They may cause significant toxicity by activating innate immunity or by eliciting an adaptive immune response against viral proteins.In addition,targeting the vector to the desired site is an issue when given systemically.The use of cells as vehicles for gene therapy vectors has many advantages.The combination of cell-viro-gene therapy has been thought as a new and promising strategy for therapy of cancer.The targeting vector to cancer stem cells will become a new direction in the field of gene therapy.In this article,we will introduce progressions,limitations and future directions of gene therapy of liver cancer.

Objective To study the restraining capability mechanism of small calibre ileum conduit anastomosed directly to the bladder in pigs. Methods 15 pigs were randomized into 5 groups according to the length of the ileal loop to form the conduit: 4cm, 5cm, 6cm, 7cm, and 8cm. In each pig, two ileal segments of the same length were reduced in calibre by opening up longitudinally and closed around a catheter. They were then directly anastomosed to the bladder end to side and placed within rectus abdominis musche in each pig. Urodynamic test, radiological image analysis and histological study were carried out 8 weeks after the procedure. Results No stenosis and twisting of the ileal ileum conduit were observed in 5cm, 6cm, and 7cm groups, in which they could be catheterized with ease. When the bladder was filled with a mean volume of 400ml of saline, the maximum "urethral" pressure ranged from 5.15～12.19kPa and the maximum close pressure (MCP) ranged from 4.83～11.27kPa. The "urethral functional length" of the ileal conduit was longer than 2cm. Among 5cm, 6cm and 7cm groups, there were no significant differences in maximum closure pressure and the urethral functional length, except in maximum "urethral" pressure. In the 4cm group, there was incontinence. Failure was found in the 8cm group because of necrosis of the ileal loop embedded in the abdominal muscle. Conclusion Small calibre conduits formed with ileum in the length of 5cm to 7cm are able to restrain urinary leakage when anastomosed directly to the bladder and and embedded in the by rectus abdominis in pigs.

Objective To investigate the effects of high loading dose of atorvastatin on lipoprotein-associated phospho?lipase A2 (Lp-PLA2) and inflammatory cytokines in patients with acute myocardial infarction (AMI), who underwent emergen?cy percutaneous coronary intervention (PCI). Methods A total of 65 cases with AMI who underwent emergency PCI be?tween October 2011 and August 2013 were randomly divided into two groups:control group (n=32, atorvastatin 20 mg/24 h) and high dose atorvastatin group (n=33, atorvastatin 40 mg/24 h). Two groups of patients were given the same basic treat?ment. Blood samples were obtained before treatment and 72 h after PCI in two groups. Levels of Lp-PLA2, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), alanine transaminase (ALT) and aspartate transaminase (AST) were detected in two groups. The adverse drug reactions were observed. Results There were no significant differences in Lp-PLA2, IL-6, TNF-α, ALT and AST levels between two groups (P>0.05). After PCI, the levels of Lp-PLA2, IL-6 and TNF-αwere significantly increased compared with those of baseline in two groups, and they were more notable in control group than those of high dose atorvastatin group (P<0.05). The levels of ALT and AST were also significantly higher after operation compared with those of basic levels (P<0.05), while there were no significant differences in ALT and AST after PCI between two groups (P>0.05). Conclusion The high loading dose of atorvastatin in AMI patients underwent emergency PCI can de?crease the inflammation and stabilize the plaques in acute stage, and which is safe.

Objective To investigate the effect of carbon dioxid insufflation on cerebral blood flow (CBF) during laparoscopic cholecystectomy. Methods Thirty patients ASA grade Ⅰ- Ⅱ undergoing laparoscopic cholecystectomy were selected. The values of jugular venous oxygen partial pressure(PjvO2 ) jugular venous oxygen saturation (SjvO2 ), arterial partial pressure of carbon dioxide (PaCO2), oxygen (PaO2) and saturation (SaO2 ) were measured before the insufflation, 10 min and 30 min after the insufnation, respectively. Results Compared with those before the insufflation, SjvO2 and PacO2 were increased significantly, and arterial--jugular venous oxygen content difference (Ca-jvDO2 ) decreased markedly 10 min and 30 min after insufflation (P
