Objective:To evaluate the usefulness of Periocheck in clinical application before and after periodontal curettage.Methods:Periocheck was applied in 65 sites in 65 adult patients with periodontitis within 15 min before and after scaling and root planing to monitor peptidase activity produced by Porphyromones gingivalis (Pg),Treponema denticola(Td) and Bacterides forsythus (Bf) in subgingival plaque. The peptidase activity was determined both spectrophotometrically and by using color standard.Results:The peptidase concentrations (Try U/L) before and after treatment were 0.44±0.23 and 0.34±0.26 (P<0.05),while Periocheck positiveness was found in 65/65 and 43/65 (P<0.01) of the patients,respectively.After treatment clinical parameters such as GI, PD,AL and peptidase concentration decreased (P<0.05) in 22 Periocheck positive patients,while those did not (P>0.05) in 43 negitive.Conclusion:Periocheck might provide a promising chair-side monitoring tool for the evaluation of scaling and root planing.

Objective To compare postoperative outcomes and complications between subtotal colectomy combined with modified Duhamel procedure and simple subtotal colectomy for severe functional constipation (SFC). Methods Between January 2006 and June 2010,40 SFC patients after strict but inefficient nonoperative treatments were randomized by number table method to control group (20 cases, receiving simple subtotal colectomy) and combined group (20 cases,receiving subtotal colectomy and modified Duhamel procedure). The selection criteria were normal colonoscopy,and abnormal dynamic proctography (DPG). The functional outcomes after surgery were assessed from 6 months to 2 years period. Results The preoperative clinical manifestations of the two groups were similar. No statistically significant difference was observed between the two groups for time for recovery of the bowel function,length of postoperative hospitalization.and the early postoperative complications (P > 0.05). Functional outcomes of combined group with CIQOL score [(110.5 ±5.0) scores],relieving of costive gastrointestinal symptoms [(79.0 ±6.5)%], recurrent constipation rate [10.0% (2/20)], satisfaction rate of defecation frequency [85.0%(17/20)], satisfaction rate of quality of life[90.0%(18/20)] were significantly better than those of control group[(90.5 ± 3.5) scores, (60.5 ± 2.8)% ,35.0%(7/20), 15.0%(3/20),20.0%(4/20)](P< 0.05). Conclusion Combined application of subtotal colectomy and modified Duhamel procedure for SFC has better outcomes.

The surgical intervention and criteria of severe acute pancreatitis has significantly changed in the last several years with the advent of enhanced imaging techniques and minimally invasive surgery.Many kinds of minimally invasive technologies which take laparoscopy as a representative are constantly applied to the treatment of severe acute pancreatitis and make its mortality and postoperative complication rate decrease obviously.However,there are many different ways using laparoscopic techniques to treat severe acute pancreatitis.In this review,the author will discuss the current status of the different approaches.

The hepatic portal system is a unique circulatory system that connects two systems of capillary beds ; one in the wall of the small intestine and spleen and the second in the sinusoidal area of the liver.Therefore,alterations in vasoreactivity (vasodilation and vasoconstriction) play a critical role in the pathophysiology of portal hypertension (PHT).The RhoA/ ROCK pathway exerts an important role in the Ca2+-independent mechanism in vascular smooth muscle (VSM).This mechanism not only modulates the constriction of intrahepatic small vessels and hepatic stellate cells (HSCs) but also effects the hyperdynamic circulation due to vascular hyporesponsiveness.Understanding the detailed mechanism and role of the RhoA/ROCK signal pathway in portal hypertension could be of great utility in providing a new target for portal hypertension therapy.

Pancreatic cancer is a common malignant neoplasm of digestive system with a fairly poor prognosis, the diagnosis rate in its early stage is low, and in recent years its incidence rate has become more and more high. Surgical remove is the only radical means, whereas only 20% of patients can get the oppotunity of surgery when the diagnosis is confirmed. More unfortunately, the five-year overall survival rate after the surgery is as low as 15 - 20%. Therefore, it is of clinical significance to improve the survival rate and to prolong survival time. Comprehensive interventional therapy has many advantages, as the technique is safe and mini-invasive with satisfactory short-term efficacy. Nowadays, interventional therapy has become the hot point in the research of pancreatic cancer. This paper aims to make a review about the current situation and progress of interventional treatment for advanced pancreatic cancer.
