Berberine is an alkaloid initially isolated from some Chinese medicinal herbs,such as Rhizoma coptidis(Huanglian),preferable for its inexpensiveness and low adverse effects as a broad-spectrum antibiotic in the treatment of various infectious diseases.More and more investigations have shown that berberine has a great potential for the treatment of digestive tract diseases.This paper updates the recent discoveries in the clinical and basic studies of berberine for the treatment of digestive tract diseases.

OBJECTIVE:To observe the clinical efficacy and safety of lactulose combined with Bacillus subtilis bifarous via-ble bacteria in the treatment of functional constipation(FC). METHODS:In a randomized double blind controlled study,60 FC pa-tients were randomly assigned into treatment group(28 cases)and control group(32 cases). Both groups received lactulose orally. Treatment group additionally receive B. subtilis bifarous viable bacteria,and control group additionally received placebo continually. 2 weeks later,both groups stopped taking lactulose but continued to take adjunctive drug till 4th week. The defecate frequencies, stool property,constipation symptoms,quality of life and ADR were compared between 2 groups before treatrnent and 2nd,4th week cofter treatment. RESULTS:In the second week ,the defecate frequencies,stool property and constipation symptoms of both groups were significantly improved,with statistical significance (P<0.05). Compared with the control group in the fourth week, these constipation symptoms of treatment group were improved more significantly,with statistical significance (P<0.05). In the fourth week,aspects of quality of life in both groups were significantly improved,with statistical significance(P<0.05);physical discomfort scores,satisfaction scores and total scores of treatment group were improved significantly,compared with the control group,there was statistical significance (P<0.05). There were no severe ADR in both groups. CONCLUSIONS:Lactulose com-bined with B. subtilis bifarous viable bacteria can effectively relieve FC,improve abdominal symptoms and slow the recurrence of constipation,which is safe and reliable.

Objective To observe the selective regulation of peroxisome proliferator-activated receptors (PPAR) on fatty acid binding protein-4 (FABP4) in human syncytiotrophoblasts.Methods Cultivate normal human syncytiotrophoblast cells,and put in the specific antagonists and agonists of PPAR each subtypes receptors,then observe the different expression of FABP4 mRNA and protein.Results Pretreated the human syncytiotrophoblast cells with the agonists (GW7647,GW0742) and antagonists (GW6471,GSK0660) of PPARα and PPARβ receptors,the expression of the FABP4 was not significantly change (P＞0.05).However pretreated with PPARγ agonists (rosiglitazone,1 × 10-9,1 × 10-8,1 × 10-7 and 1 × 10-6 mol/L),the expression of FABP4 mRNA and protein could be dose dependent-promoted significantly (mRNA:1.27 ±0.12,1.45 ±0.14,1.57±0.14,1.72 ±0.12,protein:1.10 ±0.08,1.37 ±0.09,1.60 ±0.13,1.79 ± 0.14 ; P ＜ 0.05),furthermore,the promotion can be dose dependent-reversed by specific antagonists GW9662 (mRNA:0.92 ± 0.06,0.77 ± 0.06,0.64 ± 0.05,0.55 ± 0.05,protein:0.91 ±0.03,0.78 ±0.06,0.70±0.07,0.55 ±0.06; P ＜ 0.05).Conclusions In normal human syncytiotrophoblast cells,FABP4 is a target factor of PPARγ.PPARγ regulated the expression of FABP4 mRNA and protein selectively.And the regulation will not be influenced by the other two PPAR subtypes.

Helicobacter pylori is able to colonize the human stomach and dwell in the human stomach for decades or for whole lifetime. A number of potential virulence factors contribute to Helicobacter pylori to colonize this unusual niche. Motility is an essential colonization factor based on the fact that nonmotile variants of Helicobacter pylori can't infect gnotobiotic piglets. Motility is not a colonization factor based on rapid loss of motility of Helicobacter pylori in the gastric lumen in vivo. The exact roles of Helicobacter pylori motility are not yet known. The aim of this article is to discuss correlation between colonization and motility of Helicobacter pylori.

Colorectal cancer is one of the most common malignancies in the world, and rectal cancer accounts for a large percentage of this disease in Chinese patients. Surgical extirpation is the mainstay of therapy, Intraluminal ultrasound is highly accurate in detecting depth of invasion and lymph node metastasis, and is also helpful in preoperative staging of rectal cancer. Preoperative adjuvant therapy could down-stage tumors, improve the radical resection rates of advanced lower rectal cancer, increase the rate of sphincter-saving surgery, and decrease the local recurrence rate. Total mesorectal excision could signifi-candy decrease the local metastasis of rectal cancer, and rectal cancer resection with preservation of pelvic autonomic nerve is effective in preventing urinary or reproductive dysfunction. Recently, minimally invasive surgery has been introduced for the management of rectal cancer, and transanal endoscopic microsurgery is a new method with advantages in rectal cancer treatment.
