Objective To explore the relationship among the sense of coherence,empowerment and self-efficacy in peritoneal dialysis patients.Methods General information,the Sense of Coherence Scale,the Peritoneal Dialysis Empowerent Scale-Short Form and the Self-Efficacy for Managing Chronic Disease Scale were used to investigate a total of 160 peritoneal dialysis patients in a third-class hospital in Tianjin from March to June,2015.Results The mean score of the sense of coherence,empowerment,self-efficacy were (62.01±11.94) points,(4.09±0.68) points and (6.08±2.19) points.Both the sense of coherence and empowerment could positively influence the self-efficacy of peritoneal dialysis patients directly (r=0.429-0.571,P ＜ 0.01),and the sense of coherence could also indirectly influence the self-efficacy through the mediation of empowerment (β decreased from 0.429 to 0.172,P ＜ 0.01),the mediation effect accounted for 60.1％ of the total effect.Conclusions Medical staff should take different actions to improve the sense of coherence and empowerment to improve the self-efficacy of peritoneal dialysis patients.

This article was aimed to study the factors associated with sleep quality of anger-out and anger-in population based on the frequent pattern-tree (FP-Tree) growing algorithm with data mining. The algorithm of structuring frequent model FP-tree and mining frequent itemsets were designed. The database information scanned was recorded by using FP-Tree growing algorithm through state-trees. The frequent itemsets met minimum support required was generated through reducing the search space of project sets and scanning database only one. The data mining of all factors associated with emotional diseases was actualized. The results showed that factors associated with sleep quality of anger-out and anger-in population were disturbance in respiration, cough or snoring, feeling cold, hot or nightmares. The total time for program analysis was 2 seconds. It was concluded that data mining algorithm based on FP-Tree frequent itemsets can effectively realize the useful information receiving from factors associated with emotional diseases.

Objective To study the influence of carboxymethyl-chitosan (CM-chitosan) on phenotype and proliferation of chondrocytes stimulated by recombinant human interleukin-1? (rhIL-1?), and explore its mechanism. Methods Chondrocytes were isolated and cultured. 10 ng/ml IL-1? with or without CM-chitosan of varied concentrations were added into the culture medium. After 24 h, changes of proliferative ability of chondrocytes were tested by MTT and flow cytometry. Proteoglycan synthesis was measured by incorporation of Na235SO4 into chondrocytes, nitric oxide (NO) production was detected by Greiss reaction, mRNA expression of typeⅠ、Ⅱcollagens, Aggrecan and inducible NO synthase (iNOS) were examined by semi-quantitative reverse transcription-polymerase chain reaction (RT-PCR). Results CM-chitosan could significantly antagonize IL-1?-induced inhibitory effect on proliferation of chondrocytes, restore proteoglycan synthesis of chondrocytes, decrease NO production of IL-1?-induced chondrocytes, increase the mRNA expression of typeⅡcollagen and Aggrecan, but decrease the expression of typeⅠcollagen and iNOS. The effects of CM-chitosan were in a dose-dependent manner. Conclusion CM-chitosan can maintain the proliferation and phenotype of IL-1?-induced chondrocytes.

Objective To evaluate the clinical efficacy and safety of kyphoplasty with single balloon cross-midline expansion using unipedicular approach for osteoporotic vertebral body compressive fracture (OVCF).Methods Thirty six cases of painful OVCF were included in the study,with 61 vertebrae involved.Under X-ray fluoroscopy monitoring,kyphoplasty was performed using a unilateral,single,balloon via a unilateral transpedicular approach.A final balloon position was in the midline of the vertebral body with the balloon cross-midline expansions and bone cement filled. Clinical outcomes were determined by comparison of preoperative and postoperative VAS and ODI scores.Radiographic assessment included vertebral height restoration and correction of kyphosis.Follow-up was conducted for 6.0-12.0 months(mean 9.2 months).Results Thirty-six consecutive patients with 61 vertebrae were successfully operated with an operative time of(37.4±9.6)rain per vertebra.All patients had significant pain relief and functional recovery within 96 h after the procedure with no surgery-and device-related complications.VAS score improved from(7.3±1.0)preoperatively to(2.7±0.8)postoperatively(t=19.53,P＜0.01).ODI score was decreased from(71.1±10.9)%preoperatively to(26.6±6.4)%postoperatively(t=18.54,P＜0.01).The average anterior body height loss was(14.3±2.8)mm before procedure and(10.0±1.8)mm after procedure(t=14.68,P＜0.01).The average middle body height loss was(10.2±2.7)mm before procedure and(5.9±1.8)mm after procedure(t=16.44,P＜0.01).The Cobb's angle was corrected from 23.4°±5.0° to 16.2°±2.8°(t=15.60,P＜0.01).Some leakages of cement around the anterior margin of vertebra and inter-vertebral space were found in 2 patients,but there were no clinical symptoms.X-ray examination indicated there were no cement leakages in other vertebra.The pain relief and functional recovery were substantial and maintained to the last follow up without any re-collapse or adjacent level fracture.Conclusions A single-balloon cross-midline expansion using unipedicular approach in kyphoplasty for OVCF is effective and safety,less operation time,less radiation exposure compared to the conventional kyphoplasty technique.

Objective To study efficacy and safety of large dose of pamidronate disodium in treatment for patients with painful bone metastasis of prostate cancer. Methods A total of 100 patients with painful bone metastasis of prostate cancer were randomized into large dose group and conventional dose group, with 50 cases each. Pamidronate disodium was administered by intravenous infusion, 90 mg on the first day and 60 mg on the second day for large dose group, and 60 mg on the first day and 30 mg on the second day for conventional dose group, respectively, every 4 weeks for two courses. Changes of pain,mobility, quality of life and adverse effect in patients before and after treatment were observed. Results After treatment, pain was relieved in 43 of 50 patients ( 86% ) in large dose group, significantly more than that in conventional dose group (21/50, 42% ) (χ2 = 22.79, P ＜ 0. 01 ). Both mobility and quality of life were improved in 39 and 33 patients ( 87% and 66% ), respectively in large dose group and 21 and 18 (46% and 36% ), respectively in conventional dose group (χ2 = 17.04 and 9. 00, P ＜0. 01 ). No severe adverse effect in both groups was observed. Conclusions Pain in patients with bone metastasis of prostate cancer can be significantly relieved with large dose of pamidronate disodium, as well as their quality of life improved.

BACKGROUND: In kyphoplasty procedure, two balloons are inserted into the vertebral body and inflated simultaneously for height symmetric restoration of the vertebral body. However, the expensive cost of balloon of kyphoplasty limits the extensive development of this procedure in developing countries. In this study, we try to inflate single balloon with bilateral transpedicular routes alternatively to achieve vertebral body height balanced restoration and reduce operation expenditure. But biocompatibility of bone cement and effect of kyphoplasty still need further observation.OBJECTIVE: To investigate the biocompatibility of bone cement and the clinical efficacy of bipedicular kyphoplasty for osteoporotic vertebral compression fractures by inserting single inflatable balloon into injured vertebral body and filling bone cement in the cavity caused by inflating balloon via bipedicular approach.DESIGN: Controlled observation.SETTING: Department of Medical Imaging, General Hospital of Jinan Military Area Command of Chinese PLA.PARTICIPANTS: Twenty-two patients (31 vertebral bodies) undergoing kyphoplasty with single balloon in Department of Medical Imaging, General Hospital of Ji'nan Military Area Command of Chinese PLA from May 2004 to May 2005 were selected, including 5 males and 17 females aged 68-85 years. Patients with painful compression fractures caused by osteoporosis were enrolled, and confirmed by CT and MRI with complete vertebral posterior wall but no spine deformity. The informed consent was obtained from all subjects, and the experiment and treatment were approved by Ethics Committee. METHODS: The especial instrument for kyphoplasty including puncturing device and balloon were provided by Shandong Guanlong Medical Utensils Co., Ltd. [LDAI (T) 2004 No. 2150017]; bone cement (Polymethymethacrylate) was made in China [MAIT 2005(T) No. 3650267]. Under X-ray fluoroscopy monitoring, single inflatable balloon was inserted into fractured vertebral body by puncturing needle and inflated via bipedicular approach to restore vertebral height. MAIN OUTCOME MEASURES: ①Bone cement biocompatibility during and after surgery; ②pain relief within 72 hours after surgery, restoration of vertebral height and correction of kyphotic deformity.RESULTS: ①Bone cement biocompatibility: Little cement leakage was observed at one intervertebral space of one patient by X-ray film, but no clinical symptoms, inflammatory reaction or rejection were found. ②Obvious pain relief was found in 22 cases with within 72 hours after kyphoplasty. ③The height loss of the anterior and middle vertebral body reduced from (14.70±4.21) mm and (10.62±4.11) mm preoperatively to (10.38±4.23) mm and (6.45±4.04) mm postoperatively after single balloon inflation and cement filling. Cobb angle was corrected averagely from (21.15±6.33)° preoperatively to (11.64±4.33)° postoperatively. CONCLUSION:Biocompatibility of bone cement is good, and no specific adverse effects are found in despite of cement leakage. Bipedicular kyphoplasty with single balloon for painful osteoporotic vertebral compression fractures effectively restores vertebral heights and relieves pain.

OBJECTIVETo explore effects of Shenqi preparation,Traditional Chinese Medicine, on anti-fatigue and anti-oxidant functions.

METHODSOne hundred and twenty mice were randomly divided into control group and 3 experimental groups. The high, medium and low-dose of Shenqi preparation were given to the 3 experimental groups respectively, while distilled water to the control group for 15 d. The loaded swimming time, the level of lactate, serum urea nitrogen (SUN), muscle and liver glycogen, liver super-oxide dismutase (SOD), the content of malondialdehyde (MDA), glutathione peroxidase(GSH-Px) were assayed.

RESULTSThe loaded swimming test showed that the exhausted swimming time of 3 experimental groups [(296.0 +/- 25.3)s, (437.0 ĝ 38.9)s, (595.0 +/- 53.9)s respectively] was longer than that of control group [(231.0 +/- 22.5)s, P < 0.05, P < 0.01]. The liver glycogen content of the high and medium-dose experimental groups were higher than that of control group respectively (P < 0.01). The SUN content of each experimental group was less than that of the control group (P < 0.01, P < 0.05). Moreover,in the medium and high dose experimental groups, less accumulation of lactate was found (P < 0.01, P < 0.05), and the content of liver SOD and GSH-Px was higher (P < 0.01, P < 0.05). The content of liver MDA in high-dose experimental group was less than that of the control group (P < 0.05).

CONCLUSIONShenqi preparation, especially the high and medium-dose experimental groups, is able to improve exercise tolerance and has anti-fatigue and anti-oxidant effects in mice.
