OBJECTIVETo investigate the bacterial flora and their drug resistance in hospitalized burn patients on tropical islands.

METHODSRetrospective study was carried out to analyze pathogenic microorganisms and their drug resistance characteristics in 392 burn patients hospitalized during 2000-2005.

RESULTS(1) Totally 671 strains of bacteria were isolated, among which Pseudomonas aeruginosa, Staphylococcus aureus, Aerobacter cloacae and Acinetobacter species were predominant, but the isolation rate of Pseudomonas aeruginosa was declining compared with that in 1990's. (2) The resistance rate of Pseudomonas aeruginosa to imipenem and cefepime was 32.2% and 36.7% , respectively, while that to other antibiotics was above 80%. (3) Among 141 strains of Staphylococcus aureus, 89 strains (63.1%) of MRSA were isolated, and none of them were resistant to Vancomycin.

CONCLUSIONPseudomonas aeruginosa, Staphylococcus aureus, Aerobacter cloacae and Acinetobacter species were predominant in tropical islands. The species of the pathogens are changing . The drug resistance rates of Pseudomonas aeruginosa and Staphylococcus aureus are rather high.

Based on variation of Pinus massoniana families, heritablility and correlation analysis, the contents of shikimic acid and procyanidine (heritability 0.90, 0.70), dry weight of single branch (heritability 0.60) and and leaf length (heritability 0.46) were screened out as quality, yield and harvest cost traits of Folium Pini, respectively. For the different medicinal application of Folium Pini, varied methods were chosen to estimate weight and construct index equation. Weight adjustment based.on equal emphasis were used as economic weight determining method to select the best families, and the index (accuracy 0. 936 4 and heritability 0. 881 6) obtained was a little better than that obtained by equal emphasis, and much better than that by restricted index. The superior families selected with adjustment weight and equal emphasis were No. 46, 43 and 28. Partial regression were used as economic weight determining method to select the best families,and the index obtained had the highest accuracy (0.941 5) , index heritability (0. 889 9) and the genetic gain of shikimic acid content. The superior families selected with this method were No. 46, 27 and 47. No. 46 was the best families with maximal economic benefit. Our study indicated that suitable method for estimate weight and construct index equation can be applied for better accuracy of superior families selection of P. massoniana.

Objective?To evaluate the effect on removal of ovarian cyst by laparoendoscopic single site surgery and enhanced recovery after surgery (ERAS).?Methods?A prospective, single-institution study was performed for patients who were diagnosed benign ovarian cyst, underwent removal ovarian cyst, and adopted ERAS nursing care from June 2015 to June 2017. 40 patients who adopted laparo-endoscopic single site surgery were experimental group and 40 patients who adopted traditional laparoscopy surgery were control group. We compared the operation time, blood loss volume during operation, the time of getting out-of bed after operation, the postoperative exhausting time, the defecation time after surgery, the incidence of postoperative febrile and other complications, the time of hospital stay, and hospitalization expenses between the two groups. The measurement data was tested by t test, and the counting data was tested by χ2 test, which was statistically significant with P < 0.05.?Results?The results showed that the time of getting out-of bed after operation, the postoperative exhausting time, the defecation time after surgery and the time of hospital stay in experimental group was significantly shorter than the control group;Meanwhile the hospitalization expense was lower than the control group. These results were statistically significant (P < 0.05). While there was not statistically significant in the operation time, blood loss volume during operation, and the incidence of postoperative febrile and other complications between the experimental group and the control group (P > 0.05) .?Conclusion?ERAS combined with laparo-endoscopic single site surgery is helpful to the reduction of hospitalization cost and the clinical promotion and application.

OBJECTIVETo describe an operative method for the repair of electric burn wound in the upper limbs with lateral intercostal perforator-based pedicled flap, and to observe its clinical effect.

METHODSIntercostal artery perforator-based pedicled abdominal flap with the blood supply originating from the lateral perforator branches of the 7th-10th intercostal arteries were used to repair the wounds of 6 patients with burn wounds in elbows, forearm, wrists and palms. The pedicles were (16. 0 cm x 12. 0 cm) - (9. 0 cm x 7.0 cm) in area, and the pedicles were severed 18 to 21 days after the operation. The survival and the appearance of the flaps were observed after operation.

RESULTSThe procedure was easy and safe, and there was reliable and adequate blood supply in the lateral intercostal perforator-based pedicled flap. All the flaps survived in 5 patients, except marginal necrosis (3.5 cm x 2. 0 cm) was found in the distal portion of flap because flap cutting exceeded the paraumbilical line. The appearance was satisfactory after operation.

CONCLUSIONThis flap is suitable for the repair of deep wounds in hands, forearms, and elbows.

OBJECTIVETo analyze epidemiological characteristics of burn inpatients in Hainan province over 8 years.

METHODSSix thousand and ninety-nine burn patients admitted to 6 hospitals of Hainan province from January 2002 to December 2009 were enrolled in the study. The clinical data of these patients were analyzed retrospectively, including age, gender, injury cause, wound position, burn area, ailment prior to admission, admission time, medical insurance, length of hospital stay, and mortality rate, relationship among inpatient distribution, admission time, and ambient temperature at the time of admission. Data were processed with SPSS 13.0 software.

RESULTSThere were more burn male patients than female, with ratio of 2.1: 1.0. Most patients were younger than 13 years (57.2%, 3488/6099). The most common burn area was smaller than or equal to 10% TBSA (67.4%, 4108/6099), and the fewest patients had burn areas of over 50% TBSA (2.0%, 121/6099). The main causative agents were hot liquid and flame, accounting for 71.5% (4358/6099), 17.9% (1092/6099), respectively. Most patients had injuries of more than two body areas (60.7%, 3705/6099), and lower extremity injury (17.1%, 1042/6099) was predominant in wound of single body area. Among 703 cases who had other ailments prior to admission (11.5%), the highest rate of prior ailments was found in patients older than 60 years (18.5%, 48/260), it was lowest in children younger than 1 year (8.0%, 32/398). The length of hospital stay was 1 to 375 day, and the admission time was 10 minutes to 90 days after burn. Total mortality rate was 0.4% (26 cases). The number of inpatients aged from 19 to 59 was obviously higher in months with high ambient temperature (from June to August), and for inpatients younger than 13 years the incidence of burn injury showed no obvious seasonal change. The inpatients who had medical insurance accounted for 10.9% (66/603) to 19.5% (121/619) from 2002 to 2005, which increased to 46.0% (372/808) in 2007 and 79.1% (869/1098) in 2009.

CONCLUSIONSFor burn inpatients in Hainan province, the main injury cause of burn injury is hot liquid, the number of burn adults aged from 19 to 59 seems to increase in months with high ambient temperature, while the incidence of burn in children showed no obvious seasonal change. The number of inpatients and those with medical insurance showed a tendency of increase from 2005 to 2009 in Hainan province.

OBJECTIVETo present the clinical application of composite graft of acellular allo-dermis matrix (ADM) with thin auto-microskin on burn wound.

METHODS8 inpatients with 18 full thickness skin burn wounds were transplanted with allo-ADM after eschar was excised, then the auto-microskin and allo-human skin were covered on the area of the matrix, the wound where no allo-ADM grafting were covered as control groups only with auto-microskin and allo-human skin. The area of donor to wound is 1:5 - 1:8.

RESULTSSurvived rate of 18 pieces composite skin that allo-ADM with auto-microskin were grafted were 94%. After following up for 3 to 13 months, the skins of complex grifting had well elastic and smooth texture compared to auto-microskin grafted, they appeared less cicatrisation and ulceration. 3 months after operation, it was indicated by histological examination that tightknit the epithelial-dermal conjunction and epidermal papilla structure could be identified in the allo-ADM skin and there were orderly collagenous fibres, but scar skin structure was observed in that auto-microskin grifted area.

CONCLUSIONThe graft effectiveness of allo-ADM and auto-microskin was better than that of auto-microskin, and this method could be used on major deep burn wound healing.

OBJECTIVETo review the long-term clinical effect of composite transplantation of allogeneic acellular dermal matrix (ADM) and split thickness skin autograft (STSG).

METHODSNineteen patients with 34 wounds transplanted with allogeneic ADM combined with STSG who were hospitalized from March 2001 to October 2008 were enrolled as composite transplantation group (CT). Another 9 patients with 11 wounds transplanted with STSG admitted within the same time frame were enrolled as control group (C). All patients were followed up for longer than 2 years. Color, evenness, texture, contracture, sensation, and complications of transplanted skin were assessed using a modified Manchester Scar Scale (1-4 scores, the higher the score, the poorer the situation). The scar formation on skin donor sites was assessed by the Vancouver Scar Scale. Patients' degree of satisfaction and health status during the transplantation period were investigated in the form of questionnaire. The skin tissue structure of 4 patients was observed with histological method. The joint range of motion was assessed by the neutral position before and after operation and at follow-up. Data were processed with nonparametric test, chi-square test or t test.

RESULTS(1) The evenness, contracture, and texture of transplanted skin in CT group scored (1.6 ± 0.5), (1.8 ± 0.8), and (1.5 ± 0.8), respectively, which were significantly lower than those in C group [(2.0 ± 0.7), (2.2 ± 0.9), and (2.3 ± 0.7), with Z value respectively -2.058, -2.220, -2.323, P values all below 0.05]. Scores of color, sensation, and complications of transplanted skin in two groups were close to each other (with Z value respectively -0.628, -0.428, -2.520, P values all above 0.05). (2) Mild scar formation was observed in one of the skin donor sites in CT group. (3) Information as obtained from questionnaire showed no statistical difference between two groups in pinching, itching, and satisfaction degree (with χ(2) value respectively 0.187, 0.019, 2.628, P values all above 0.05). (4) Nerve fibers were seen in hand tissue 2 years after operation. ADM did not induce severe inflammatory responses in the site of grafting. (5) Eleven joints in CT group recovered or improved in function; while the other two joints required secondary surgery. Obvious contracture was observed in the two joints in C group.

CONCLUSIONSAllogeneic ADM combined with STSG transplantation prevents scar contracture and has obvious effect in improving function and appearance. There is no problem in regard to safety for its existence in either adult or children.

OBJECTIVETo investigate the clinical efficacy of acupotomy stress position percutaneous dynamic release for severe shoulder periarthritis.

METHODSFrom April 2012 to August 2016, 160 patients with severe shoulder periarthritis were randomly divided into treatment group and control group. Among them, 80 patients in treatment group were treated with acupotomy stress position percutaneous dynamic release including 32 males and 48 females with an average of(52.47±9.04)years old ranging from 40 to 74 years old;the courses of disease was(20.72±9.55)months on average. The other 80 patients in control group were treated with simple joint loosening according to Maitland technique in grade III-IV therapy, once a day, 15 to 20 min each time, and 10 d for 1 course, for a total of 2 courses, including 33 males and 47 females with an average of (53.19±10.18) years old ranging from 42 to 75 years old; the average course of disease was (21.98 ±8.99) months. After operation, the shoulder muscles training and shoulder joint activity training were routinely conducted, the treatment lasted for 3 weeks. The visual analogue scale(VAS) and Constant-Murley shoulder function score were observed and compared between the two groups before treatment and 3 weeks, 3, 6 months after treatment.

RESULTSThe VAS scores of the treatment group at 3 weeks, 3 and 6 months after treatment were all lower than those of the control group(<0.05). The shoulder joint function Constant-Murley scores of the treatment group at 3 weeks, 3 and 6 months after treatment were higher than those of the control group (<0.05); the result was excellent in 59 cases, good in 18 cases, fair in 3 cases in the treatment group; excellent in 15 cases, good in 31 cases, fair in 23 cases, poor in 11 cases in the control group, and the difference between the two groups was statistically significant(<0.01).

CONCLUSIONSTreatment of severe shoulder periarthritis with acupotomy stress position percutaneous dynamic release can obviously improve the shoulder joint function and pain, according to the different parts of the shoulder joint pain and function limitation, the corresponding shoulder stress and body position should be designed and maintained during the treatment process, and the angle of stress position gradually increased by loosening the adhesion, which is the key to ensure the curative effect.

Diabetic foot wound repair is a challenging issue in clinical practice. Due to the influence of multiple factors including the damage and regeneration failure of local tissue, the impaired pathways of wound repairing through blood vessels and nerve nutrition, and disorders of a variety of cellular factors, traditional treatment methods are often difficult to achieve good therapeutic effects. Stem cells are a type of cells with potentials of multidirectional differentiation, which also possess functions such as regulating immunity and paracrine to facilitate the comprehensive wound repair, so they have promising application prospect at present for the treatment of diabetic foot wounds. Because the relevant parameters of stem cell treatment are in the exploratory phase, there were no standardized data. This paper reviews the application of stem cells in the research of diabetic foot wound treatment over the past 6 years, analyzing and summarizing the contents in focused aspects including the types and sources of stem cells, effects of donor age and gender on stem cells, mode of administration, transplantation survival rate and safety, which may provide a reference for further application of stem cells in the clinical treatment of diabetic foot wound.
