Background: Gastric cancer surgery is major surgery and often encountered in surgical. Objectives: To assess the efficacy and the side effect of postoperative patient \ufffd?controlled epidural analgesia (PCEA) with bupivacaine \ufffd?fentanyl after gastrectomy. Subjects and method:A prospective trial was conducted on 30 patients with gastrectomy because of cancer. Epidural catheter was inserted at level of D7-D9. Postoperative pain relief using PCEA with bupivacaine 0,125% - fentanyl 2\u03bcg/ml: 2ml bolus every 10 min, with basal infusion 2ml/h. VAS during normal tidal ventilation and following cough, the side effects were monitored during 48 hour period. Results: VAS decreased from 6,4 \xb1 1,4 to 2,6 \xb1 0,7, p<0,01 after 15 min. 90% patients had VAS under 2,5 after 1 hour and 100% reached VAS under 2,5 after 8 hours during normal tidal ventilation and following cough as well. Incidence of urinary retention, nausea and pruritus were 13,3; 3,3; and 3,3% respectively. Conclusion: PCEA provided a effective pain control after gastrectomy during normal tidal ventilation and following cough. The side effects remained unusual and minor.

BACKGROUND: Stochastic resonance whole-body vibration training (SR-WBV) was tested to reduce work-related musculoskeletal complaints. METHODS: Participants were 54 white-collar employees of a Swiss organization. The controlled crossover design comprised two groups each given 4 weeks of exercise and no training during a second 4-week period. Outcome was daily musculoskeletal well-being, musculoskeletal pain, and surefootedness. In addition, participants performed a behavioral test on body balance prior to when SR-WBV started and after 4 weeks of SR-WBV. RESULTS: Across the 4-week training period, musculoskeletal well-being and surefootedness were significantly increased (p < 0.05), whereas musculoskeletal pain was significantly reduced only in those who reported low back pain during the last 4 weeks prior to the study (p < 0.05). Body balance was significantly increased by SR-WBV (p < 0.05). CONCLUSION: SR-WBV seems to be an efficient option in primary prevention of musculoskeletal complaints and falls at work.

Pain and anxiety engender major psychic problems during all phases of treatment for burn patients. Analgesic alone does not allay these problems satisfactorily in these patients. Music therapy, as an important complementary and alternative therapy, has been widely used in multiple medical fields. However, its positive effect on alleviation of pain and anxiety in burn patients is undefined. The objective of this review is to summarize the feasibility, application fields, methods, and the effectiveness of music therapy in allaying pain and anxiety of burn patients during the whole course of treatment.

OBJECTIVETo explore an exercise method for the prevention and treatment of the patients with shoulder and back fasciitis.

METHODSFrom 2006.8 to 2008.3, 120 patients with shoulder and back fasciitis were randomly divided into control group (n = 60, including 21 females and 39 males, the average age was (47.0 +/- 12.0) years, and the average course of disease was (14.1 +/- 12.0) months) and treatment group (n = 60,including 19 females and 41 males, the average age was (43.7 +/- 9.9) years, and the average course of disease was (16.4 +/- 13.4) months). The patients in the control group received massage therapy and the ones in the treatment group were treated with massage therapy and horizontal bar exercise. After 3 weeks treatment, the curative effects of the patients in two groups were observed. All the patients were followed up for 6 to 26 months, the recurrence were observed.

RESULTSAfter 3 weeks treatment, the scores of pain, sense of heaviness, strip sign, tenderness, shoulder and back function of the patients in two groups had significant differences compared with those before treatment (all P < 0.01). After treatment, the scores of pain, sense of heaviness, strip sign, tenderness, shoulder and back function of the patients in the treatment group were lower than those in the control group (P < 0.05). After 6 to 26 months following-up, the rate of recurrence in the treatment group was lower than that in the control group (P < 0.01).

CONCLUSIONHorizontal bar exercise is a simple, no expense and effective method in the prevention and treatment of shoulder and back fasciitis, which can improve the effect of the treatment and reduce the rate of recurrence.

OBJECTIVETo systematically evaluate the efficacy and safety of preoperative administration of cyclooxygenase-2 (COX-2) inhibitor on pain occurring with total knee arthroplasty (TKA).

METHODSWe electronically searched PubMed, Cochrane Library, EMBASE, CNKI, CBM, Wanfang data from inception to March 15, 2014 and manual searched journal of library collection to identify randomized controlled trials (RCTs) about preoperative administration of COX-2 inhibitor on pain occurring with TKA. The methodological quality of the included RCTs was assessed and the data were extracted according to the Cochrane Handbook 5.1.0. Meta-analysis was performed by using RevMan 5.2 software.

RESULTSA total of 6 RCTs involving 228 patients were included. The results of meta-analyses showed that: (1) Efficacy: The visual analog scale (VAS) of post-operation at 12-hour (WMD = -0.60, 95% CI -0.83 to -0.37, P < 0.000 01) and 24-hour (WMD = -0.74, 95% CI -1.29 to - 0.19, P = 0.008) was decreased when COX-2 inhibitor was used before operation. And compared with control group, experimental group decreased the modified numerical pain rating scale (MNPRS) at 24-hour (WMD = -0.50, 95% CI -0.70 to -0.30, P < 0.000 01), 48-hour (WMD = -0.55,95% CI -0.65 to -0.45,P < 0.000 01) under quiescent conditions, and the same result at 24-hour (WMD = -0.82, 95% CI -1.26 to -0.38, P <0.000 01), 48-hour (WMD = -0.71, 95% CI -0.82 to -0.60, P < 0.000 01) under active conditions. The morphine consumption postoperatively were fewer in experimental group at the first day (WMD = - 1.35, 95% CI -1.92 to -0.79, P < 0.000 01) and the second day (WMD = -1.60, 95% CI -2.68 to -0.52, P = 0.004). (2) Safety: COX-2 inhibitor could lessen the incidence of postoperative pruritus (RR = 0.35, 95% CI 0.15 to 0.84, P = 0.02), but not statistically decrease of nausea and vomiting (RR = 0.83, 95% CI 0.54 to 1.28, P = 0.40) and exhaustion (RR = 0.63, 95% CI 0.05 to 7.67, P = 0.72).

CONCLUSIONThe current evidence indicated that preoperative administration of COX-2inhibitor can effectively improve the effect of postoperative analgesia, reduce the consumption of morphine and lessen the incidence of pruritus. Due to the limited quantity of the included studies and the evidence with limited strength,further high-quality RCTs are needed to verify the aforementioned conclusion.

AIMTo observe the protection effect of a new combined anti-G measure which was composed of KH-x anti-G suit, unassisted PBG (positive pressure breathing for G, PBG) and PHP maneuver. The problem of fatigue and pain when using this measure was also discussed.

METHODSFive fully qualified centrifuge subjects were exposed to 5 groups of +Gz exposure: (1) relaxed tolerance, (2) KH-x and KT-x, (3) PBG, (4) 6.5 G 45 s, (5) 9.0 G 15 s. The subjective feeling of fatigue and pain induced by +Gz exposure was evaluated by the questionnaire after runs.

RESULTSThere was no incidents of G-induced lose of consciousness in this study. The protective effect of KH-x and KT-x was 2.3 G while it was 1.7 G for PBG. All the subjects have accomplished the 4th and 5th runs. The pain has developed on neck, waist, arm and hands. The problem of waist pain was very significant.

CONCLUSIONThe new combined anti-G measure could meet the requirement of +9.0 Gz protection for high performance plane. How to prevent the occurrence of neck injury and alleviate the pain induced by G when using this measure should be studied further.

BACKGROUNDSeated workplaces have greatly increased in China. Many researchers have found that seated work is a risk factor in the development of low-back pain. Backrest can reduce the load on the lower back by transmitting more of the weight from the upper body to the floor via the backrest so as to prevent low-back pain. To design a suitable chair backrest for seated office work, some backrest parameters must be optimized. In this study, the role of backrest density on lumbar load and comfort were investigated. The goal of the study was to help establish criteria with which backrests that alleviate and prevent low back pain during seated office work can be designed and selected.

METHODSTwenty volunteers (10 men and 10 women) were seated in three backrest conditions (10 kg/m(3), 25 kg/m(3), and 40 kg/m(3)). Pressure data, including contact pressure (CP), peak contact pressure (PCP) and contact area were collected during 15-minute trial. Subjective data were collected after each pressure test.

RESULTSBackrest density had a significant effect on backrest pressure variables. CP and PCP increased with increasing backrest density. Contact area decreased with increased density. In terms of user preference, the backrest with low density was most highly rated.

CONCLUSIONSBackrest density plays an important role in lumbar load and comfort during seated work. During designing and selecting backrests, backrest density should be focused on so as to alleviate and prevent low-back pain during seated office work. Backrest density at 10 kg/m(3) got the lowest CP and PCP and largest contact area. Backrest with low density can reduce lumbar pressure and increase support contact area, which could raise comfort feeling. Backrest density at 10 kg/m(3) is better to maintain a balance between providing effective support and alleviating excess lordosis.

OBJECTIVETo investigate the epidemiological characteristics of lower back pain of truck drivers in plateau areas with an analysis of the causes and evaluated the effects of the protective measures.

METHODSThe self-reported lower back symptom was investigated by questionnaire in 1,132 male drivers in plateau areas. Vibration of the driver lumbar back was measured real time with or without wearing corset. Study the effect of the special corset for drivers and the massage on back by self-control design of big sample intervention experiments.

RESULTSThe prevalence of lower back pain of drivers in plateau areas was 86.1%. High level of its prevalence is due to many factors. Special corset for drivers and massage on back by themselves can reduce the degree of the pain.

CONCLUSIONDriving in plateau areas is a special occupational work with high level of prevalence of lower back pain which can be prevented.
