Objective: To observe the analgesic effect and adverse effects of Controlled-Release Oxyco-done tablets(oxycontin) on moderate and severe chronic cancer pain, and the improvement of quality of life(QOL) in the cancer patients after the treatment. Methods: A total of 72 patients with moderate and se-vere chronic cancer pain were selected .The analgesic effects,adverse effects and quality of life (QOL) were observed and evaluated. Controlled-Release Oxycodone tablets were administered at an initial dose of 5 mg or 10 mg every 12 hours according to the degree of pain. The next analgesic dose should be adjust-ed if breakthrough pain occurs more than twice in 24 hours. If the initial dose is 5 mg, it may be increased to greater than or equal to 10 mg. If the initial dose is greater than or equal to 10 mg, the dosage may increased by 25%～50%. Short-acting morphine tablets are used to control the breakthrough pain. Results: The doses ranged between 10～100mg/d .Among the 72 patients with moderate and severe chronic cancer pain, 12 (16.7%)achieved complete remission ,52(72.2%)achieved partial remission,6(8.3%) achieved minor remis-sion.The overall rate of pain relief 88.9%. The mainly adverse reactions were including, nausea and vomiting, dizziness, drowsiness and dysuria. Followed the reduced of the pain intensity ,the QOL of most cancer pa-tients was improved. The KPS of 12 patients had been obviously improved, 20 patients had mildly improved, and 40 patients were stabilized. Conclusion: Oxycodone hydrochloride controlled-release tablets are effective and safe for the management of chronic cancer patients with moderate and severe pain, with less adverse reactions, and the QOL of cancer patients were significantly improved.

OBJECTIVE To analyze the changes in bacteria constitution in severe burn wounds in different stages so as to provide reference for clinical prevention and treatment.METHODS A total of 36 casualties with severe burn injuries(≥50.0% total burn surface area) and hospitalized within 5 days post-burns from 2004 to 2006 were enrolled in the study.Samples were collected in the burn wounds from the first day to two months post-burns.RESULTS Totally 476 bacterial strains were isolated and Gram-negative bacteria accounted for 64.1%.However,in term of the single bacterial strain,Staphylococcus aureus(SAU) ranked first and the follows were Pseudomonas aeruginosa(PAE) and Acinetobacter baumannii(ABA).During the first week and the six weeks to 2 months post-burns,Gram-positive bacteria were dominant and SAU ranked first.From the second week to the fifth week,Gram-negative bacteria were dominant,PAE and ABA were the main bacteria.Even though Gram-negative bacteria dominated in these periods,SAU still ranked the first or the second in terms of single bacterial strain.CONCLUSIONS Bacteria constitution in burn wounds differs in different stages.It must be stressed to prevent infections of SAU regardless of any stages,as well as ABA infections since the percentage of ABA has increased markedly in recent years.

Objective To study the clinic value of digital three-dimensional shaping titanium mesh in repairing skull defects and reconstructing temporal muscle attachment points. Methods Eighty-two patients with skull defects from December 2013 to January 2016 were enrolled in this study. They were divided into two groups according to patients' will with 41 patients in each group. The patients in control group received traditional hand-shaping titanium mesh repair, the patients in observation group received individual digital forming technology to produce titanium mesh repair and reconstruct the temporal muscle attachment points at the titanium mesh temporal corresponding position. The rate of appearance satisfaction, operation time, the number of titanium nail and the rate of postsurgery adverse reaction was compared between the two groups. Results The rate of appearance satisfaction in observation group was significantly higher than that in control group: 97.56%(40/41) vs. 80.49%(33/41), P<0.05. The operation time and the number of titanium nail and in observation group was significantly lower than that in control group:(8.9 ± 1.6) h vs. (12.4 ± 2.4) h, (10.3 ± 0.9) pieces vs. (11.8 ± 1.8) pieces, P < 0.01. The rate of postsurgery adverse reaction in observation group was significantly lower than that in control group: 0 vs. 9.8%(4/41), χ2 = 4.21, P < 0.05. Conclusions The operation of repairing skull defects and reconstructing temporal muscle attachment points with digital three-dimensional shaping titanium mesh is simple. It can shorten the operation time, decrease the postsurgery adverse reaction, and increase the appearance satisfaction.

Objective To compare the difference of wound healing quality of composite skin grafting consisting of xenogeneic (porcine) acellular dermal matrix (PADM) combined with micro-autograft or split-thickness autograft of skin. Methods Seventy-two Sprague-Dawley rats with full-thickness skin defect on the back were randomly divided into three groups,namely test group I with PADM with split-thickness autologous skin,test group II with HADM with autologous micro- skin and allogeneic skin graft,and control group with autologous micro-skin with allogeneic skin graft to cover the skin defect area respectively. The take rate and the condition of wound healing,and also the rates of wound contraction were calculated. Tissue samples were harvested for histological examination. Results The wound contraction was less in test group I and II than that in control group( P

Bacille Calmette–Guerin (BCG) vaccination for protection against tuberculosis has been in use for long. Although the vaccine is safe, its administration can result in complications such as BCG adenitis. We report here a series of children with BCG adenitis with a view to recognise and manage this condition. It is hoped that this case series would encourage the increased identification of this condition.

Objective To observe the effect of low molecular weight heparin(LMWH)on hypercoagulability in extensive severe burn patients.Methods 9 patients were assigned as LMWH treatment group(TG),and another 12 burn patients with the similar extent of burn injury admitted in the same period were assigned as routine treatment group(RTG).All the treatments were the same except 5000U LMWH was given via subcutaneous injection per 12 or 6 hours to the TG group for 3-7days.The patients in normal control group(NCG)consisted of patients receiving plastic surgery.The following coagulation parameters were determined before and after the heparin treatment:prothrombin time(PT),thrombin time(TT),activated partial thromboplastin time(APTT),international normalized ratio(INR),fibrinogen(Fib)and platelet(PLT).Results INR,APTT and PLT in both TG and RTG groups were significantly lower compared with that in NCG before treatment,and Fib in two former groups were higher than that in NCG.Compared with those values before treatment,Fib decreased and PLT increased significantly after LMWH treatment in TG.However,there were no significant changes in other parameters in TG after LMWH treatment.Severe side effects such as haemorrhage were not found in patients in TG.Conclusion LMWH could ameliorate hypercoagulability following severe burns.
