1.Tendinopathy enthesiopathy in athletes
Chinese Journal of Tissue Engineering Research 2007;11(23):4658-4660
BACKGROUND: Enthesiopathy, one of the three tough problems in sports medicine is a frequent disease in athletes;treatments to enthesiopathy determine the performance record and sports span of athletes in a big extent.DATA SOURCES: The relevant articles from 1990 to 2006 were searched for in NCBI Entrez PubMed by input the key words "enthesiopathy" and "tendinopathy" in English into a computer. Similarly, the relevant articles in Chinese from 1994 to 2006 were searched for in CNKI and Wangfang Data.STUDY SELECTION: Articles about preclinical and clinical research of enthesiopathy in athlete, the excluded articles were those about repetitive studies.DATA EXTRACTION: A total of 20 relevant literatures were collected, including 16 included articles and 4 excluded articles due to repetitive study.DATA SYNTHESIS: ① The main structure of ten-insertion which is very multiplicity contains 4 different tissues, the main function of it is to transmit and absorb shocks. ② So far it is not very clear about the etiopathogenisis and pathological change of enthesiopathy; It is considered that enthesiopathy actually is the result of decompensation in the ten-insertion and degeneration of collagen fiber and cartilaginous is the main pathological change; ③ Nonoperative therapy can abate the clinical symptom, but the curative effect is not affirmative.CONCLUSION: So far it is very clear about the anatomic structure of ten-insertion, but it is not very clear about the etiopathogenisis and pathological change of enthesiopathy and the relationship between enthesiopathy and apoptosis.Scientific and reliable therapies are scarce, strict design and random research of the existing therapies to enthesiopathy are very necessary; for importance, research and exploratory in other therapies including gene therapy and cell factor therapy is a very hopeful direction of the treatment in enthesiopathy.

Objective To explore the risk factors for methicillin-resistant Staphylococcus aureus (MRSA)infection of refractory wound,and provide reference for clinical prevention and control.Methods Clinical data of patients who were isolated Staphylococcus aureus (SA)from wound at the burn ward in a hospital from January 2006 to December 2013 were analyzed,patients were divided into four groups according to whether the isolated SA were MRSA and whether SA were from refractory wound or from non-refractory wound.Risk factors for MRSA infection of refractory wound were analyzed. Results A total of 112 isolates of SA were isolated from wound,statistical differences existed in the length of hospital stay,recent invasive operation,and recent antimicrobial use between patients in refractory wound MRSA group and refrac-tory wound methicillin-sensitive SA (MSSA)group (all P <0.05);non-conditional logistic regression analysis revealed that length of hospital stay>30 days (OR 95% CI :1.14-30.69)and recent invasive operation (OR 95% CI :1.41 -17.84) were independent risk factors for refractory wound MRSA infection.There were statistically differences in previous MRSA infection,burn depth,recent operation and recent antimicrobial use between refractory wound MRSA group and non-refrac-tory wound MRSA group(all P <0.05);non-conditional logistic regression analysis revealed that recent antimicrobial use (OR 95% CI :2.080-26.800)was independent risk factor for the persistence of MRSA infection of refractory wound. Conclusion Shortening the length of hospital stay,reducing invasive operation,and using antimicrobial agents ra-tionally are helpful for the prevention and control of MRSA infection of refractory wound.

Objective To evaluate the effects of different analgesics combined with propofol of intravenous anesthesia on postoperative analgesia and emotion in patients of artificial abortion. Methods One hundred and twenty-two patients who had underwent painless artificial abortion were selected. The patients were divided into 4 groups by random digits table method: simple propofol group (C group, 29 cases), fentanyl combined with propofol group (F group, 30 cases), oxycodone combined with propofol group (Q group, 30 cases) and sufentanil combined with propofol group (S group, 33 cases). The induced dose of propofol was 2.5 mg/kg. When patients had limb movement during operation, a single addition of propofol 0.5 mg/kg was added until the body movement disappeared. The changes of mean arterial pressure (MAP), heart rate and respiratory rate before and after operation were compared among the 4 groups. The emotional status was assessed with affective scale before operation and 1 h after operation. The visual analog scale (VAS) was used to evaluate the degree of abdominal pain at 10, 30 and 60 min after palinesthesia. The propofol dose, operation time, recovery time and adverse reaction were recorded. Results No obvious adverse reactions were found during the operation. There was no statistical difference in operation time among 4 groups (P>0.05). The propofol dose, recovery time, body movement and the VAS score at 10, 30, 60 min after palinesthesia in F group, Q group and S group were significantly lower than those in C group, and there were statistical differences (P<0.05);but there were no statistical difference among F group, Q group and S group (P>0.05). The MAP, heart rate and respiratory rate at beginning of the surgery and during the surgery were significantly lower than that before anesthesia in the 4 groups, and there were statistical differences (P<0.05); but there were no statistical differences in MAP, heart rate and respiratory rate among 4 groups (P>0.05). The positive affective score after operation in C group, F group, Q group and S group was significantly higher than that before operation: (24.6 ± 5.6) scores vs. (21.7 ± 6.2) scores, (24.6 ± 3.1) scores vs. (20.6 ± 4.6) scores, (28.3 ± 6.3) scores vs. (20.8 ± 5.3) scores and (25.2 ± 5.4) scores vs. (19.9 ± 4.8) scores, and the negative affective score after operation in C group, F group, Q group and S group was significantly lower than that before operation: (17.0 ± 5.3) scores vs. (29.7 ± 7.4) scores, (17.2 ± 3.0) scores vs. (30.8 ± 5.0) scores, (16.1 ± 5.1) scores vs. (30.4 ± 4.9) scores and (17.9 ± 4.0) scores vs. (32.1 ± 5.5) scores, and there were statistical differences (P<0.05). The positive affective score after operation in Q group was significantly higher than that in C group, F group and S group, and there was statistical difference (P<0.05). There was no statistical difference in negative affective score after operation among 4 groups (P>0.05). Conclusions The fentanyl, sufentanil and oxycodone combined with propofol of intravenous anesthesia in patients underwent artificial abortion can reduce propofol dose, shorten recovery time, improve positive affective score, decrease negative affective score and strengthen the analgesic effect, and doesn't increase the adverse reaction. The respiratory and circulatory inhibition effects of different analgesics combined with propofol of intravenous anesthesia were similar, but oxycodone can increase positive affective score.
