[Nucleosides-based identification model for Fritillariae Cirrhosae Bulbus].

A high performance liquid chromatography( HPLC) method was established for the fast,and precise determination of ten nucleosides in Fritillariae Cirrhosae Bulbus and its counterfeits. Then multivariate statistical analyses,such as clustering analysis,principal component analysis( PCA),and Fisher' s linear discriminant analysis( LDA),were conducted to establish a discriminant function model for an integrated analysis. The results indicated that data acquisition time of a single sample was shortened within 16 min by the HPLC method.

A simple and effective method to discern the true commercial Chinese cordyceps from counterfeits.

The Chinese cordyceps, a complex of the fungus Ophiocordyceps sinensis and its species-specific host insects, is also called "DongChongXiaCao" in Chinese. Habitat degradation in recent decades and excessive harvesting by humans has intensified its scarcity and increased the prices of natural populations. Some counterfeits are traded as natural Chinese cordyceps for profit, causing confusion in the marketplace.

MiR-138/peroxisome proliferator-activated receptor β signaling regulates human hypertrophic scar fibroblast proliferation and movement in vitro.

Excessive scars affect a patient's quality of life, both physically and psychologically, by causing pruritus, pain and contractures. Because there is a poor understanding of the complex mechanisms underlying the processes of hypertrophic scar formation, most therapeutic approaches remain clinically unsatisfactory. In this study, we found that miR-138 was downregulated and peroxisome proliferator-activated receptor (PPARβ) was inversely upregulated in hypertrophic scar tissues compared to in paired normal skin tissues.

[Effects of herbivorous insect stress on the growth and yield-related traits of insect-resistant transgenic rice].

A field experiment was conducted to test the effects of high and low herbivorous insect stresses on the growth, development and yield-related traits of insect-resistant transgenic rice. Three Bt transgenic rice Bt63, R1 and R2 were selected as the test materials, and non-transgenic rice Shanyou63 was taken as the control. The differences in the vegetative growth, seed-setting, and stem borer resistance between transgenic and non-transgenic rice were compared.

[The use of composite sodium lactate and sorbitol composition in fluid resuscitation for shock in patients with major burn].

Objective: To investigate the feasibility of the use of sodium lactate and sorbitol (CISS) in the fluid resuscitation for shock in patients with major burns.

Methods: Fifty - three adult patients with major burns (hospitalized within 6 hours after burns) were randomly divided into A (n = 24, with i.v.

[Repair of rabbit tendon by autologous bone marrow mesenchymal stem cells].

Objective: To investigate the effect of rabbit bone marrow mesenchymal stem cells (MSCs) as seed cells for the repair of tendon defect.

Methods: The MSCs were isolated, amplified and identified by detection of surface protein CD44 mRNA. A 3 cm long defect was made in the Achilles tendon of the rabbit.

[Interchange of facial scar flap with upper arm subdermal vascular network skin flap to improve facial appearance].

Objective: To evaluate the result of subdermal vascular network skin flap raised from the upper arm to interchange with a facial skin flap carrying a scar resulted from previous burn.

Methods: A transit flap was designed in the anterior medial aspect of the upper arm according to the reverse design method. The subdermal vascular network flap in the upper arm with length-width ratio less than 1.

[Long-term result of repair of deeply burned hands with large sheet of split-thickness autoskin grafting with the preservation of denatured dermis].

Objective: To evaluate the long-term results of repair of burn hands with large sheet of split-thickness autoskin grafting with the preservation of denatured dermis.

Methods: One hundred and fifty-two hands in 86 burn patients with deep partial thickness and full thickness burn were enrolled in the study. The burned hands were treated by tangential excision and grafted with large sheet of split-thickness autoskin with the preservation of denatured dermis.

[Repair of the penial injury in patients inflicted by high-voltage electrical injury].

Objective: To explore the repair and reconstruction of penial defect in patients inflicted by high-voltage electrical injury.

Methods: Among one hundred and fifty three patients inflicted with high-voltage electrical injury, 6 suffered from penial injury (including 3 with necrosis of whole penis, 1 with partial necrosis of penis, 1 with partial necrosis of penial shin and 1 with necrosis of entire skin of penis) were enrolled in the study. The penis was repaired by direct suture of the residual skin following excision of necrotic skin in one case, by skin grafting in two case, by scrotum skin flap transplantation in 3 cases.
