Objective To systematically evaluate the effectiveness of aloe vera and its products (e.g. dressing for external use, and gel) for both acute (e.g. laceration, surgical incision, and burn) and chronic (e.g. infectious wound, and artery and venous ulceration) wounds. Methods With “aloe” and “wound” as the index words, such databases as Cochrane Library, PubMed, EMbase, CBM, CNKI and VIP were searched from the inception to April, 2012 to collect the randomized controlled trials (RCTs) about aloe vera or its products for treating acute and chronic wounds. Two authors independently screened literature, extracted data and assessed the risks of bias. Then meta-analysis was conducted using RevMan 5.0 software. Results A total of 15 RCTs involving 773 participants were included, and all studies were of low quality. There were 8 RCTs which evaluated aloe vera for treating acute wounds (burn, haemorrhoidectomy, and skin biopsy), and no RCT reported the incidence of infection. Compared with silver sulfadiazine, aloe vera products could increase the proportion of healing wounds for patients with burn (RR=1.28, 95%CI 1.03 to 1.60, P=0.03 ); compared with antibiotic cream, aloe vera products could reduce the average healing time for patients with burn (MD= ?12.90, 95%CI ?13.29 to ?12.51, Plt;0.000 01); compared with conventional therapy, aloe vera gel could increase the proportion of healed patients with acute surgical wounds (RR=16.33, 95%CI 3.46 to 77.15, P=0.000 4), and could increase the proportion of healed patients with pressure sores (RR=1.73, 95%CI 1.21 to 2.49, P=0.003). Conclusion The application of aloe vera topical agents and dressings is positively significant to both acute and chronic wounds. But this conclusion still needs to be supported by high quality trials.
Objective To investigate the injury types, dysfunction situation and rehabilitation deamnd of the Lushan earthquake victims. Methods The rehabilitation demand of 208 Lushan earthquake victims in the West China Hospital of Sichuan University were investigated using a questionnaire. Results Bone fractures accounted for the largest proportion of injury types, followed by combined injuries, soft tissue injuries, pulmonary contusion, and amputation. Most victims suffered from the motor dysfunction, balance disorder and restrictions in activities of daily living. More than 80% of victims had pain. A few victims had paresthesia and respiratory disorder. Most victims needed rehabilitation assistant devices and hospitalization treatment. Conclusion The injury types and dysfunction situation of Lushan earthquake victims are associated with the demand of rehabilitation assistant device. The tailored rehabilitation regimen can be made in combination with victim’s rehabilitation demand. The early intervention of rehabilitation medicine is extremely beneficial to the recovery of earthquake victims.
Objective To explore the effectiveness and safety of topical phenytoin for wound healing. Methods We searched MEDLINE (1966 to Oct. 2002), EMBASE (1984 to 2002), The Cochrane Library (Issue 4, 2002), Biological Abstracts (1993 to 1996), Cancerlit (1997 to Sept. 2002), Life Science Collection (1982 to Mar. 1995), International Pharmaceutical Abstracts (1970 to 2002), and CBMdisc (1978 to Jan. 2003). Controlled trials on topical phenytoin for wound healing were identified. The methodological quality of included studies was assessed, and a descriptive analysis was performed. Results Nine studies (507 cases) including 1 randomized controlled trials (RCT) and 8 non-randomized controlled trials were included. These studies were of poor methodological quality. Because there were a variety of etiology of ulcers, differnet interventions in control groups, and different outcome measures, for which meta-analysis was difficult to perform, a descriptive analysis of the results was presented. Most studies showed that topical phenytoin had better effects on improving healthy granulation appearance, increasing complete recovery rate, reducing time for complete recovery, and positive cases of bacterial culture than those of control groups. Mild side effects were observed in only one study.Conclusions The reviewers think that the inclusion studies less rigorous than randomized controlled trials could result in misleading findings.Some well designed randomized controlled trials of topical phenytoin for wound healing are warranted.
目的 分析下肢慢性创伤性骨髓炎患者创面细菌培养分布情况，为临床用药提供依据。 方法 对2006年1月－2010年12月收治的91例慢性骨髓炎患者创面分泌物细菌培养标本结果进行回顾性调查分析。其中男78例，女13例；年龄5～78岁，平均41.3岁。病程47 d～7个月，平均68.6 d。使用抗生素总疗程均＞7 d。 结果 65例创面细菌培养阳性患者共分离出113株病原菌，其中G?菌72株，占63.71%；G+菌41株，占36.28%。药敏结果显示，G+菌对常规青霉素类基本耐药，碳青霉烯类耐药菌株少见，对万古霉素耐药菌株尚未出现。G?菌对青霉素类及头孢菌素类耐药较高，对头孢哌酮－舒巴坦无耐药。 结论 加强对慢性创伤性骨髓炎患者创面病原菌监测极为必要,对临床抗生素的合理使用具有一定的指导意义。Objective To analyze the distribution of cultured bacteria from chronic osteomyelitis patients, and provide a basis for clinical medicine. Methods We retrospectively analyzed the bacterial culture results of the secretions from 91 patients with chronic osteomyelitis treated in our hospital from January 2006 to December 2010. Among them, there were 78 males and 13 females aged from 5 to 78 years averaging at (41.3 ± 8.35) years. The duration of the disease ranged from 47 days to more than 7 months, averaging (68.6 ± 14.57) days. The total course of antibiotic-taking was longer than 7 days for all the patients. Results A total of 113 pathogen strains were isolated from 65 secretion samples, including 72 Gram-negative bacteria accounting for 63.71% and 41 gram-positive bacteria accounting for 36.28%. Drug susceptibility results showed basic resistance of Gram-positive bacteria to conventional penicillin, rare resistance to carbapenem, and no resistance to vancomycin. Gram-negative bacteria were basically resistant to penicillin and cephalosporins, but not resistant to cefoperazone-sulbactam. Conclusion Enhancing the monitoring of pathogens for patients with chronic osteomyelitis is extremely necessary for the rational clinical use of antibiotics.

【Abstract】Objective To investigate prophylactic measures for nontraumatic complications of laparoscopic cholecystectomy (LC).Methods The data of 13 000 patients who underwent LC in Kunming general hospital of PLA over 13 years(1991-2004) were retrospectively reviewed. Results Nine malignant tumors and 47 common bile duct stones were missed at LC. The 9 malignant tumors included hepatic cancer (n=1), gastric cancer (n=1), gallbladder cancer (n=2), pancreatic cancer (n=2) and right colon cancer (n=3). Of all the carcinomas, 3 patients with right colon cancer underwent colectomy, the other 6 patients couldn’t be cured radically. All the 47 patients with choledocholithiasis were cured successfully, among them 31 patients were performed with ERCP and 16 were reoperated on with cholangiotomy. Conclusion This study emphasizes the necessity to analyze carefully patients’ symptoms before operation and pay attention to pathological changes of gallbladder and intraabdominal situation intraoperatively. If necessary, laparoscopic ultrosonography can be used to avoid missing malignant tumors and biliary stones.
【Abstract】ObjectiveTo study the positive effect of recombinant human epidermal growth factor (rhEGF) on rabbit intestinal anastomotic wound healing after bowel resection. MethodsFortyeight white rabbits were randomly divided into study group in which rhEGF was injected and spinged in the submucosa and mucosa respectively during intestinal anastomosis after bowel resection, and control group in which only intestinal resection and anastomosis was performed. The leukocyte was counted. The incidence of anastomotic leakage and the synthesis of collagen fibrils and hydroxyproline were observed. ResultsThe leukocyte numbers in the anastomotic tissue in two groups rabbits increased slightly 3 d, 5 d and 7d after intestinal anastomosis, but the difference between study group and control group was insignificant (Pgt;0.05). The incidence of anastomotic leakage in the control group (16.7%) was higher than that of the study group (4.3%). The area of collagen fibrils 3 d, 5 d and 7d after intestinal anastomosis in the study group were significantly more than that in the control group (P＜0.05). Number of fibroblast was higher in the study group and the cells appeared bigger nucleus and dense colouration as well as enriched plasm. Angiogenesis in anastomosis tissue in the study group was significant and normal structure was present. Cell structure of anastomosis mucosa was damaged in the control group. Synthesis of hydroxyproline in anastomotic tissue 5 d and 7 d after anastomosis in the study group was more than that in the control group (P＜0.05).ConclusionInflammation was present in the whole process of wound healing, and local using of EGF had insignificant effect on system inflammation. EGF functions as chemoattractant and increases the recruitment of leukocytes, monocytes and fibroblasts into the wound area. EGF increases the production of collagen, angiogenesis and the synthesis of hydroxyproline. So EGF could promote wound healing and protect from anastomosis leakage in this study.
