Purpose: Intraoperative ultrasound was used to assess the flow velocity in the marginal vessel arch adjacent to the anastomosis, critical for evaluating the anastomotic blood supply. This technique also enabled us to investigate the potential effects of preserving the left colonic artery on the perfusion of the anastomosis.

Methods: This prospective study included 40 rectal cancer patients who underwent laparoscopic anterior resection between January 2021 and January 2023.

Objective: To develop a rapid method for the detection of Down syndrome (DS) using dual-color competitive quantitative fluorescent polymerase chain reaction (DCC-QF-PCR), and to assess its feasibility for the prenatal diagnosis of Down syndrome.

Methods: DNA was extracted from peripheral blood of 30 DS patients and 60 normal men, common primers for DSCR and USC2 genes and respective TaqMan probes were designed and synthesized. The results of DCC-QF-PCR were compared with those of QF-PCR which measured the ratio between DSCR and GAPDH.

Objective: To explore the effect and mechanism of ligand pioglitazone (PGZ) activating PPAR-gamma on the invasiveness of cholangiocarcinoma cell in vitro.

Methods: Human hilar cholangiocarcinoma cell line QBC939 was selected and cultured in vitro for this research. The rate of QBC939 cell growth inhibition was detected by MTT, and the influence of PGZ on the expression of MMP-7 mRNA and TIMP-1 mRNA was measured by using FQ-PCR.

Objective: To evaluate the expression of glucocorticoid receptor alpha (GRalpha) and beta (GRbeta) messenger RNA (mRNA) in orbital tissues from thyroid associated ophthalmopathy (TAO).

Methods: Samples of extraocular muscle and orbital fat were obtained from 17 patients with TAO and 10 healthy individuals. Total RNA was extracted and reversely transcripted into cDNA.

Hemophilia A affects male, whereas females are carriers and generally spared from this disease. However, we here reported a 65-year-old female with Hemophilia A while screening the gene mutation of coagulation factor VIII. The female went to hospital because of tripping to lead her right chest to be injured with subcutaneous hematoma.

Objective: To reduce the rate of accidental false negative result in the HBV DNA PCR test on clinical serum samples.

Methods: A competitive polymerase chain reaction (C-PCR) was used to decrease the false negative ratio. In the C-PCR, a constructed inner control DNA was added for co-amplification with the HBV target DNA.
