[In vivo reflectance spectroscopy study of different clearing agents on human skin optical clearing].

The changes of skin tissue reflectance spectroscopy before and after being treated with the optical clearing agents of three different types of optical clearing within the wavelength rang of 400-1 000 nm, and the degree of changes in reflectance spectroscopy of each group skin during 0-60 min at 580 nm in vivo were real-time dynamically researched. The reflectance spectroscopy of skin tissue before and after being dealt by the optical clearing agents of glycerol, glucose and propylene glycol was measured using a USB-4000 fiber spectrophotometer at 0, 10, 20, 30, 40, 50 and 60 min. The results showed that the reflectance spectral intensity was distinctly decreased, but the reflectance was significantly increased gradually with the time prolonged.

Expression and clinical significance of syndecan-1 mRNA and HPA-1 mRNA in colorectal cancer detected with real-time fluorescent quantitative polymerase chain reaction.

Background And Objective: Invasion and metastasis are the most common causes of mortality for patients with colorectal neoplasms, and blocking invasion and metastasis in a timely fashion has become a hot research focus. We investigated the expression of the messenger RNA of Syndecan-1 and HPA-1 in colorectal cancer, and their correlation with invasion and metastasis.

Methods: Real-time fluorescent quantitative polymerase chain reaction (PCR) was used to detect the expression of Syndecan-1 and HPA-1 in specimens from 49 patients with colorectal cancer, 49 paired adjacent colorectal neoplasms (2 cm from the carcinoma), and 49 surgical margins of paired normal colorectal mucosa tissue (5 cm from the carcinoma), to analyze their correlation with clinicopathologic characteristics of colorectal neoplasm.

[Adjuvant effect of transcutaneous electrical acupoint stimulation in propofol-fentanyl anesthesia in partial mastectomy].

Objective: To evaluate the adjuvant effect of transcutaneous electrical acupoint stimulation (TEAS) in propofol-fentanyl anesthesia in partial mastectomy.

Methods: Ninety patients undergoing partial mastectomy were randomly divided into 3 groups (n=30), namely group A with propofol-fentanyl anesthesia (PFVA), group B with PFVA and TEAS at Hegu-Laogong and Neiguan-WaiGuan acupoints, and group C with PFVA and TEAS at Hegu-Laogong, Neiguan-Waiguan, and bilateral Jianjing acupoints. The bispectral index (BIS), heart rate (HR), saturation of pulse oxygen (SpO2), blood pressure (BP), the reaction of patients to the incision and awakening quality were observed at different time points.
