A new modified forked flap and a reverse V shaped flap for secondary correction of bilateral cleft lip nasal deformities.
The columella, nasal tip, lip relationship in the bilateral cleft lip nasal deformity remains a great challenge for plastic surgeon. An esthetically satisfying result is difficult to obtain. A subset of patients with bilateral cleft lip nasal deformity still require columellar lengthening and nasal correction and philtrial construction. This study aimed to provide a new method based on the forked flap to improve the final appearance of these patients. ⋯ This method makes maximum use of the tissue containing the scar in the lip and limits tissues in the lower portion of the columella and the prolabium for adequate columella elongation and reconstruction with normal size philtrial dimensions. It is a very reasonable and useful method in correction of secondary bilateral cleft lip nasal deformities.

Cyclooxygenase-2 promoter polymorphism -899G/C is associated with hepatitis B-related liver cancer in a Chinese population of Gansu province.
Hepatitis B virus infection is closely related to hepatocellular carcinoma (HCC). Cyclooxygenase-2 (COX-2) is overexpressed in HCC and considered to play a role in hepatic carcinogenesis. In this study, we analyzed the polymorphism of COX-2 promoter -899G/C in healthy controls, chronic hepatitis B (CHB) patients, liver cirrhosis patients, and hepatocellular carcinoma (HCC) patients, to investigate the relationship between COX-2 -899G/C polymorphism and the risk for hepatitis B-related liver cancer in a Chinese population from Gansu province. ⋯ COX-2 -899C genotype may increase the susceptibility of individuals to hepatitis B-related liver cancer in Gansu province, China.

Long-term outcomes of gemcitabine and cisplatin in patients with recurrent or metastatic esophageal squamous cell carcinoma: a phase II trial.
Esophageal cancer is the sixth most common cause of cancer-related death worldwide. Prior studies had demonstrated potential synergistic antitumor activity of gemcitabine in combination with cisplatin. Therefore, we studied the efficacy and tolerability of such combination for esophageal cancer. ⋯ This cisplatin-gemcitabine regimen was manageable and had significant efficacy in patients with esophageal squamous cell carcinoma. Patients with a response had improved survival time. Furthermore, a small number of the patients with metastatic esophageal cancer were still alive in 5 years with this regimen.

Allergen micro-array detection of specific IgE-reactivity in Chinese allergy patients.
Allergen micro-arrays are powerful tools for screening of serum IgE-reactivity. In this study allergen micro-arrays were used to identify dominating IgE-binding allergens and cross-reactivity patterns among selected Chinese allergy patients. ⋯ This study clearly confirms that group 1 and group 2 are major allergens of house dust mites. These selected house-dust mite allergy patients are close to being mono-sensitized. Der p 10 is not an important allergen for cross-reactivity. Specific IgE-sensitization towards pollen allergens is low in southern China compared to other regions. The prevalence of food and stinging insect allergens known to give rise to IgE-mediated cross-reactivity is 2% or less.

Application of labeled radioimmunoimaging tracing in detecting pulmonary embolism in rabbits after bone cement perfusion and relevant treatment effects.
During the process of bone cement joint replacement, some patients show a series of complications, such as a sudden drop in blood pressure or dyspnea. The cause of the complication is considered to be due to emboli caused by the femur prosthesis insertion. The purpose of the present study was to detect the pulmonary embolism in rabbits after bone cement perfusion by radioimmunoimaging, and to explore its protective measures. ⋯ Radioimmunoimaging is an alternative method for the dynamic observation of rabbit pulmonary embolism after bone cement perfusion. Radioimmunoimaging is the optional way to evaluate the effect of pretreatment with epinephrine hydrochloride or fibrin sealant on pulmonary embolism after bone cement perfusion.
