Endoscopic ultrasound was initially introduced in 1980s as a diagnostic modality combining echoendoscopes with radial scanning, which permitted reconstruction of cross-sectional images similar to computed tomography. Many studies showed that endogastric ultrasonography is more accurate than endoscopy or CT in evaluating the depth of invasion ( T category) and the involvement of lymph nodes (N category) in patients with gastric carcinoma. In addition to being very useful in tissue acquisition for diagnostic purposes, the principles behind endoscopic ultrasound-guided fine needle aspiration ( FNA) paved the way for the development of therapeutic endoscopic ultrasound, which improve the prognosis of patients with gastric cancer.

Objective: To explore the effects of hydrogen sulfide (H 2S) on hypoxic pulmonary vascular smooth muscle cell (VSMC) apoptosis in rats. Methods: Twenty four Wistar rats were divided into 3 groups: control group ( n =8), hypoxia group ( n =8), and hypoxia +NaHS group ( n =8). The plasma level of H 2S was determined by methylene blue spectrophotometric method. VSMC apoptosis was measured by terminal deoxynucleotidyl transferase biotin nick end labeling (TUNEL). The protein expressions of Bcl 2, Fas and caspase 3 in pulmonary arteries were detected by immunohistochemical technique. Results: Compared with rats in the control group, the plasma level of H 2S decreased by 36% in rats of hypoxic group . The apoptotic rate per area in VSMCs detected with TUNEL was significantly decreased by 52.9% in rats of hypoxic group . The expressing integral score of Bcl 2 of VSMCs was increased by 123.9%,while Fas protein expression of VSMCs was decreased by 45% and caspase 3 protein expression of VSMCs was not significantly changed in rats of hypoxia group. But compared with rats in the hypoxia group, the plasma level of H 2S increased by 65% in rats of hypoxia+NaHS group. The apoptotic rate in VSMCs of TUNEL was significantly increased by 62.5% in rats of hypoxia+NaHS group. The Bcl 2 protein expression of VSMCs was decreased by 36.4% in rats of hypoxia+NaHS group. The expressing integral scores of Fas and caspase 3 were significantly higher in rats of hypoxia+NaHS group than in those of hypoxia group. Conclusion: Hypoxia decreased the pulmonary artery smooth muscle cell apoptosis. H 2S inhibited Bcl 2 protein expression of VSMCs and activated Fas and caspase-3 protein expressions of VSMCs, and therefore promoted the pulmonary artery smooth muscle cell apoptosis.

Objective To develop a phenylketonuria (PKU) screening method based on a compact disk (CD) type microfluidic chip capable of generating reciprocating flow within the microchannels that facilitate rapid DNA hybridization. Methods This microfluidic device consists of a two-layer structure: a polydimethylsiloxane (PDMS) top layer containing 12 DNA hybridization microchannels, and a bottom glass layer with immobilized hydrogel conjugated DNA arrays. The DNA arrays included R243Q, V245V and the blank control probes. When the CD device was spun, the PCR products were driven into the hybridization channel by centrifugal force. When the rotation of the CD device was stopped, capillary force pulled the PCR products solution to flow back to the channel. After the on-chip hybridization, the hybridization signals were captured on a fluorescence microscope. The specificity, detection limitation and reproducibility of this device were evaluated. Thirty DNA samples from pregnant women with suspected PKU were detected by this device.Then the results were compared with DNA sequencing results. Results With the compact disk type microfluidic chip, the hybridization time could be reduced to 15 min, sample consume could be as low as 1. 5 μl and the detection limitation was 0. 7 ng/μl. With the chip based method, samples of PKU patients and healthy controls were detected and the results were consistent with DNA sequencing results. Five different batches of chips and five micro-channels of each chip were selected to test one PKU patients with V245V mutation. All the results were positive, indicating good reproducibility. Four cases of V245V mutation and 1 case of R243Q mutation were found in 30 suspected PKU carried pregnant women. Conclusion The compact disk microfluidic device has advantages of simple, rapid and highly sensitive, thus is well suited to PKU screening.
