Effectiveness of recombinant human growth hormone ( rhGH) in treating critically ill or severe burned patients have been demonstrated. Although adverse effects of rhGH have also been identified, they are controllable. The dosage and timing of rhGH must be well designed, and hyperglycemia be controlled. Application of rhGH in critically ill patients should be deliberately considered.

Chronic diseases (ChDs) today constitute the leading cause of morbidity and mortality. Increasing evidence suggests that the production and development of ChDs are associated with amplified inflammation, which is caused by accumulation of advanced glycation end products (AGEs) and advanced lipexidation end products (ALEs).Heating, irradiation, and ionization, in combination with gross over-nutrition, significantly contribute to production of, exposure to and accumulation in the body of AGEs/ALEs. Furthermore, dietary AGEs restriction in animals seemed to be effective to extend life span. This paper elucidates the relationship between food and AGEs and the dietary measures to reduce AGEs/ALEs with an attempt to provide new methods for prevention and treatment of ChDs.

Objective: To evaluate the clinical effectiveness and safety of early total enteral nutrition (TEN) in severely burned patients. Methods: Forty one burned patients with total burn surface area over 30% were randomly assigned to TEN group (n=21) and CONT group (n=20). The two nutritional support protocols were similar in calorie and nitrogen intake within 7 d of treatment. Serum levels of visceral proteins and TNF-? were measured. Prognostic inflammatory and nutritional index (PINI) was postulated from formula. Results: Contrasting to a significant reduction (from 96.0?31.8mg/L to 69.4?17.3 mg/L, P

Nutrition Risk Screening 2002 (NRS 2002) was developed on the basis of 128 randomized controlled clinical studies by a group of experts led by Kondrup from the European Society for Parenteral and Enteral Nutrition (ESPEN).As the first evidence-based nutritional screening tool worldwide,NRS 2002 has been recommended for nutritional risk assessment of hospitalized patients in Europe for the addition of disease metabolism and its simplicity.In this article,we reviewed the increasing applications of NRS 2002 in China,pointed out the existing problems and made several suggestions on improvement for popularization and standardization of its clinical use.

Objective To study demographic features,clinical characteristics and in-hospital cost of patients due to different causes in one center in 2007-2011 and discuss their correlation.Methods A retrospective analysis was conducted on all patients who were treated with amputation from 2007 to the first half of 2011 in the Second Affiliated Hospital of Zhejiang University to carefully record their data,such as demographic characteristics,entity,medical history,clinical information,amputation location,amputation level,hospital day and medical cost.Results A total of 805 patients at age of (42.1 ± 18.1)years underwent amputation from 2007 to the first half of2011.Among them,the male patients accounted for 72.3％.The patients engaged in farm,industry and transportation accounted for 69.7％.Traumatic amputation occupied 66.1％,followed by 15.3％ of tumor amputation and diabetic amputation proportioned 4.5％,occupying 13.2％ of non-traumatic amputation.Ratios of lower limb amputations and amputations above levels of joints of palmar digitals and toes were 64.9％ and 61.7％.Mean hospital day was 20 days (range,14-34 days) and mean medical cost was 15 000 RMB (range,8 881-31 975 RMB).Conclusions Amputation largely occurs in the male adults and mainly results from trauma.High amputation,long hospital stay and high medical cost are the main characteristics.

OBJECTIVETo observe the effectiveness of xenogenic(porcine) acellular dermal matrix grafting with thin autogenic skin on deep wounds with good wound-bed.

METHODS52 cases of patients with deep wounds were transplanted with xenogenic(porcine) acellular dermal matrix grafting and thin autogenic skin by two step method from Jan. 2000 to Feb. 2002.

RESULTS37 cases of patients achieved complete take(71.1%) and 15 cases got 95 percent take (28.9%) with none needing grafting again. 3-6 months' following up showed that skins of complex grafting had well-acceptable color and quality compared to nearby skin.

CONCLUSIONThis kind of xenogenic(porcine) acellular dermal matrix can be widely used on deep wounds with good wound bed as complex graft.

Objective To observe the infection prevention, wound healing effect and safety of nanometer silver in treatment of Ⅱ degree burn wound. Methods The patients with 6%-10% TBSA Ⅱ degree burn wound ( deep or superficial) were randomly divided into test group ( treated with nanome-ter silver, n =35) and control group (treated with 1% sulfadiazine silver, n =35). Each group was reg-ulated to change dressing and medication one time a day for seven days on 5% superficial Ⅱ degree burn wound. Then, 1% iodophors and gauze were used for change dressing. Before and after change dressing, bacterial culture was done in two groups to observe the time for wound healing. The blood collected before change dressing and at days 1,7 and 14 after change dressing and urine within 24 hours were employed for detecting serum silver level and mean silver level in urine by using inductively coupled plasma mass-spec-trum ( thermoelectricity of American Ⅹ Series Ⅱ ). In the meantime, the liver and renal function was e-valuated at days 7 and 14. Results Positive rate of bacterial culture in test group and control group was 3% and 3.1% respectively after treatment, which showed a decrease compared with the levels before treatment (12. 1% and 15.6% respectively), with no statistical difference. The wound healing time of test group was (9. 18 ± 1.9) days, which was shorter than ( 12.9 ± 1.3 ) days in control group, with sta-tistical difference (P<0.01). Before treatment, the silver level of blood was ( 1.55 ± 1.26) μL and ( 1.54 ± 1.28 ) μg/L respectively in test group and control group, and silver level of urine within 24 hours was ( 1.67 ± 1.05 ) μg and ( 1.87 ± 1.37) μg respectively test group and control group, with no statistical difference (P > 0. 05 ). Silver medication could elevate the serum silver level ( P < 0.01 ), with lower level in test group than control group (P <0. 01 ). Average silver level of urine within 24 hours showed similar change with that in the serum. The patients showed normal renal function, with no abnormal change of ALT. Conclusions For Ⅱ degree burn wound, nanometer silver can more significantly short-en wound healing time compared with sulfadiazine silver. Moreover, nanometer silver has higher degree of safety on silve metabolism and is an ideal medcation for burn wound.

The essential internal environment in human being involves water, electrolyte, and acid-base balance, which is the basis of balance and stability of internal environment in other systems. For burn patients, the balance of internal environment, referring to metabolism, nutrition, inflammatory response, and immunoreaction, is one of the most important aspects in burn disease. This paper aims to briefly elaborate the balance of internal environment after burn, with the purpose to promote the basic and clinical research in this field.

Severe skin damage not only causes a mass of tissue defect, but also leads to the loss of various sensory functions. Tissue engineering skin provides a new way for high-quality wound repair, while there are still many problems in the recovery of sensory function, such as abnormality or loss of sensation of pain, touch, and temperature. Therefore, when tissue engineering skin is used to promote wound healing, regeneration and functional recovery of sensory nerve have attracted more and more attention. This article introduces the kind, distribution, regeneration, and factors influencing regeneration of sensory nerve in skin, and explores strategies in promoting regeneration of sensory nerve from dermal scaffold, seed cell, and neurturin of tissue engineering skin.
