Biofilm Formation Characteristics of Pseudomonas lundensis Isolated from Meat.

Biofilms formations of spoilage and pathogenic bacteria on food or food contact surfaces have attracted increasing attention. These events may lead to a higher risk of food spoilage and foodborne disease transmission. While Pseudomonas lundensis is one of the most important bacteria that cause spoilage in chilled meat, its capability for biofilm formation has been seldom reported.

[Depth of focus in spherical and aspheric intraocular lenses].

Objective: To investigate depth of focus (DOF) in spherical and aspheric IOL eye models.

Methods: Computer numerical simulation experiment was used. IOL eye model based on Liou-Brennan eye model was constructed by using ZEMAX optical design software.

Antitumor effects of recombinant human interleukin-6 on mouse bladder carcinoma through Fas-mediated apoptosis.

Purpose: An apoptosis-inducing therapy is gradually becoming a new strategy for cancer treatment. The aim of this study was to investigate the mechanism of growth-inhibitory effects of recombinant human interleukin-6 (rhIL-6) on bladder tumor-bearing T739 mice in vivo.

Methods: Murine bladder transitional carcinoma cells (BTT739) were inoculated subcutaneously into T739 mice as a tumor model for evaluating the antitumor effects of rhIL-6.

[Effects of Liuweidihuang Decoction on cell proliferation and melanin synthesis of cultured human melanocytes in vitro].

Objective: To investigate the effects of Liuweidihuang Decoction on the proliferation and melanin synthesis of cultured human melanocytes in vitro.

Methods: MTT assay was used to assess the proliferation of cultured human melanocytes after treatment with Liuweidihuang Decoction, and NaOH assay was employed to determine melanin synthesis.

Results: Liuweidihuang Decoction at the concentration of 5%-15% did not affect the proliferation of the melanocytes (P>0.

[A comparison of curative effects of percutaneous nephrostomy and open surgery in the management of postrenal acute renal failure].

Objective: To investigate the effects and clinical value of percutaneous nephrostomy (PCN) in the management of postrenal acute renal failure (PARF).

Methods: The clinical data of 40 cases of PARF for the treatment of PCN and 20 cases with open surgery were retrospectively analyzed.

Results: The success rate of PCN was 100%, renal function of all patients was restored to normal range after 2-7 days of PCN, in whom 30 patients recovered.

[Relationships between tumor shrinkage and peripheral blood cell changes during tumor-rejection induced by a high dose of 5-FU in C57BL/6 mice].

Aim: To investigate the relationship between the alterations of complete blood counts and tumor shrinkage during tumor rejection induced by a high dose of 5-FU in C57BL/6 mice.

Methods: Wild type C57BL/6 tumor-bearing mice were treated with different doses of 5-FU intraperitoneally. 75 mg/kg 5-FU was the minimal effective dose of 5-FU that could cure the tumor-bearing mice.

[Relationship between sensitivity of tumor cells to chemotherapeutic agent in vivo and in vitro: experiment with mouse lymphoma cells].

Objective: To study the relationship of the sensitivity of tumor cells to chemotherapeutic agent between in vivo and in vitro.

Methods: Mouse lymphoma cells of the line E14 were cultured and melphalan resistant EL4 cell line (EL4/melphalan) was established by culturing EL4 cells with continuous low-concentration and intermittent gradually-increasing-concentration of melphalan in vitro. MTT assay was used to evaluate the drug sensitivity and the resistance index of the EL4/melphalan cells to melphalan was calculated.

[Evaluation of absolute alcohol treatment for renal cyst with percutaneous puncture and catheterization under ultrasonographic guidance].

Objective: To evaluate the effect of absolute alcohol treatment for renal cyst with percutaneous puncture and catheterization.

Methods: This report presented 64 cases of renal cysts, 34 cases were treated with percutaneous puncture (A group) and 30 cases with percutaneous catheterization (B group). According to the size, the cysts were divided into 2 groups, more than 6 cm in diameter and less than 6 cm in diameter.

Optimal margin in nephron-sparing surgery for renal cell carcinoma 4 cm or less.

Objective: Renal cell carcinoma (RCC) of 4 cm or less is with a low incidence of multicentricity and metastasis and is usually considered suitable for nephron-sparing surgery (NSS). This study was designed to investigate the distance between extra-pseudocapsule cancer lesions and primary tumors, and to suggest the optimal margin of normal parenchyma in NSS for RCC 4 cm or less.

Methods: We prospectively studied 82 kidneys in which RCCs of 4 cm or less were resected by radical nephrectomy.

[Optimal margin in nephron-sparing surgery for renal cell carcinoma 4 cm or less in diameter].

Objective: To investigate the optimal margin in nephron-sparing surgery (NSS) for renal cell carcinoma (RCC) 4 cm or less in diameter.

Methods: Eighty-two kidneys with RCC 4 cm or less in diameter resected by radical nephrectomy were prospectively studied. The kidney samples were sectioned at 3 mm interval and examined for multicentricity.
