What contribute to the biological behaviors of gastric carcinomas?

Gastric carcinoma is one of the most frequent malignant tumors in the world. The gastric carcinoma cell with fibroblastic pattern which intracellular adhesion was decreased showed active mobility and invasiveness,which indicated that the EMT was placed. The TJ protein participated in EMT of tumors. Four transmembrane proteins of claudin family were essential component of TJ, but the effect of the TJ protein in the development of cancers was not clarified, especially the effect of claudin-1 expression transformation in gastric carcinomas.

Is local anesthetic wound infusion following laparotomy effective for colorectal surgery?

Although suboptimal postoperative pain control is associated with cardiovascular, respiratory and gastrointestinal complications, many multimodal regimens for analgesia following major colorectal laparotomy provide inadequate pain relief. Continuous wound infusions of local anaesthetics are a promising development as an adjunct to existing multimodal postoperative analgesic regimens. There is a need for a focused, quantitative review of the evidence specific to colorectal laparotomy.

High blood pressure takes big toll on small filtering units of the kidney

Take a kidney out of the body and it still knows how to filter toxins from the blood.

But all bets are off in the face of high blood pressure.

"How does the kidney know how to do it and why does it break in hypertension?" says Dr. Edward W. Inscho, physiologist in the Medical College of Georgia Schools of Medicine and Graduate Studies.

Introducing the next generation of chemical reactors

Unique nanostructures which respond to stimuli, such as pH, heat and light will pave the way for safer, greener and more efficient chemical reactors.

Being developed by a consortium of UK universities, the nanostructures can regulate reactions, momentum, and heat and mass transfer inside chemical reactors. This technology will provide a step change in reactor technology for the chemical, pharmaceutical and agrochemical industries.

Cells that mediate steroid-resistant asthma identified by scientists at Children's Hospital

Children's Hospital of Pittsburgh of UPMC researchers have identified cells that may play a key role in some forms of steroid-resistant asthma, a complication of the condition that makes treatment even more challenging.

The identification of a lineage of cells known as T Helper Type 17 (Th17) may help scientists in the development of new treatments that lead to better control of asthma, according to the study's senior author, Jay K. Kolls, MD, chief of the Division of Pediatric Pulmonary Medicine, Allergy and Immunology at Children's Hospital.

A new diagnostic tool for colorectal cancers prognosis

To analyze the clinical significance of BAMBI, authors studied its expression in CRC using immunohistochemical staining. They show that BAMBI overexpression is correlated with aggressive tumor phenotypes and predicts tumor recurrence and cancer-related death in CRC. BAMBI may be usable as a target for diagnostic and antibody medicine.

A new combined treatment of biliary cast syndrome

Biliary cast syndrome is a syndrome which is characterised by the presence of casts causing obstruction of the biliary tree, thus leading to biliary infection, hepatocyte damage secondary to bile stasis and ductal damage, all contributing to cholangiopathy. The development of total biliary cast is very uncommon, especially in non-transplant patients. The etiology of biliary cast formation in these cases is uncertain but several factors are believed to play a role, including periods of fasting, hemolysis, cholangitis and recent surgery.

A rare case of inflammatory myoglandular polyp

IMGP is characterized by inflammatory granulation tissue in the lamina propria, proliferation of smooth muscle, and hyperplastic glands with variable cystic change. Only a small number of cases have been reported and the pathogenesis and natural history remain unclear.

What's the main risk factor of gallstone disease?

Gallstone disease is a very common gastrointestinal disorder: in fact it has been documented that more than 14% of adults are, or have been, affected by this disease. Therefore, gallstones are a major public health problem, and this disorder is one of the most common and costly of all digestive disease, at least in the Wester World.

How to diagnoses and treat biliary rhabdomyosarcoma efficiently?

BRMS is an uncommon cause of recurrent jaundice and conjugated hyperbilirubinemia in children. Because its presentation may mimic that of a choledochal cyst, the correct diagnosis is frequently made intraoperatively at a planned choledochal cystectomy. However, identification of this entity prior to surgery is important because early surgery may carry excess morbidity and mortality.

How to treat steroid-naive ulcerative colits patients efficiently?

The etiology of UC is believed that an immune abnormality may be involved in its development. Steroid has long been the second line therapy for the induction to remission in UC, if remission cannot be achieved by salazosulfapyridine or mesalazine treatment. However, steroid administration can occur various side effects. LCAP has been reported to be effective for steroid-refractory or steroid-dependent patients with UC; however, the data of LCAP for steroid-naïve patient with UC is limited.

What is sign for progressive of colorectal carcinoma?

The process of tumor invasion and metastasis is associated with alterations in the functions of several adhesion molecules. In general, tumor cells lose their capacity for normal adherence, which facilitates their detachment from their site of origin. alpha-catenin links E-cadherin to the actin cytoskeleton via its association with either beta- or gamma-catenin. Reduced alpha-catenin expression was associated with tumor invasion and metastases in colorectal cancer (CRC).

Is OB glue paste technique ideal to establish nude mouse transplantation model?

Establishment of human gastric cancer nude mouse transplantation models has undergone three representative stages: subcutaneous transplantation of cell suspension, gastric wall seeding of cell suspension, and intra-gastric wall transplantation of histologically intact tissue, of which the fresh tissue orthotopic transplantation model has two types: the "suture method"and the "gastric bursa method".But the "suture method"or the "gastric bursa method" transplantation has many practical difficulties and disadvantages in establishing the model; for example, the tumor tissue is easy to fall off

How to prevent liver damage induced by anti-tuberculosis treatment?

About one third of the world's population has latent tuberculosis and roughly 9 million cases of active tuberculosis emerge annually resulting in 2-3million deaths. Most new cases occur in the most populated nations like India and China. Combination chemotherapy containing Isoniazid (INH), Rifampicin (RMP), Pyrazinamide (PZA) with or without ethambutol for initial 2 months followed by a continuation phase of 4-6 months of Isoniazid and Rifampicin is the preferred regimen for successful treatment and for preventing acquired resistance.

What induce local recurrence of rectal carcinoma?

It is well known that local recurrence is the most important prognostic factor of rectal carcinoma. However, even after undergoing radical resection of primary tumors and lymph nodes, about 4%-50% of patients with rectal carcinoma were reportedly with local recurrence. Clinicopathologically, the risk factors of local recurrence remain unclear heretofore. Therefore, a group from Guangdong Provincial People's Hospital has recently explored the risk factors of local recurrence after curative resection in patients with middle and lower rectal carcinoma.
