Synthesis and Optical Properties of Lead-Free Cesium Tin Halide Perovskite Quantum Rods with High-Performance Solar Cell Application.

Herein, the fabrication of a lead-free cesium tin halide perovskite produced via a simple solvothermal process is reported for the first time. The resulting CsSnX (X = Cl, Br, and I) quantum rods show composition-tunable photoluminescence (PL) emissions over the entire visible spectral window (from 625 to 709 nm), as well as significant tunability of the optical properties. In this study, we demonstrate that through hybrid materials (CsSnX) with different halides, the system can be tunable in terms of PL.

[Make efforts to improve overall levels of clinical nutriology in China].

Clinicians should assume the responsibility of nutritional therapy for satisfactory outcomes. They should master knowledge on nutritional metabolism, and participate in the administration of nutritional support. Clinicians should be acquainted with new concepts and standardized techniques in this field, such as different requirement of energy, understanding of early nutritional support, and optimal regimens of enteral or parenteral nutrition.

[Assessment of energy expenditure and body composition in cancer patients].

Objective: To demonstrate the changes of resting energy expenditure (REE), substrate metabolism and body composition in cancer patients.

Methods: From September 2004 to March 2008, REE, carbohydrate oxidation (CO) and fat oxidation (FO) in 936 cancer patients and 840 control subjects were measured by indirect calorimetry. Bioelectrical impedance appliance was applied to assess intracellular fluid, extracellular fluid, fat mass (FM) and fat free mass (FFM) in the two groups.

[A randomized controlled trial of postoperative artificial nutrition in malnourished patients with gastrointestinal cancer].

Objective: To investigate the potential benefits of postoperative nutrition in malnourished patients with gastrointestinal cancer.

Methods: A total of 646 malnourished patients with gastrointestinal cancer defined by the subjective global assessment (SGA) were randomly divided into parenteral nutrition group (n=215), enteral nutrition group (n=215) and conventional group (n=216). Two nutritional regimens were designed to be isocaloric 125.

[Therapeutic effects of hepatic resection in liver metastasis of colorectal cancer].

Objectives: To evaluate therapeutic effects of hepatic resection in liver metastasis of colorectal cancer (LMCC).

Methods: The clinical data of 133 cases of LMCC received hepatic resection from January 1, 2000 to December 31, 2005 in Zhongshan Hospital were analyzed retrospectively. The relationship between hepatic resection and survival rate was also concerned.

[Survival of patients with liver metastasis from colorectal cancer by different modes of therapy: a report of 363 cases].

Objective: To evaluate the correlation between different therapies and survival of liver metastasis from colorectal cancer ( LMCC) , and to compare the clinical outcome of synchronous liver metastasis (SLM) with that of metachronous liver metastasis (MLM).

Methods: The clinical data of 363 patients with LMCC were retrospectively reviewed with focus on the correlation between different therapy and survival.

Results: Of these 363 patients, 160 had SLM and 203 had MLM.

[Effects of glucagon-like peptide 2 on the adaptation of residual small bowel in a rat model of short bowel syndrome].

Objective: To investigate the effects of glucagon-like peptide 2 (GLP-2) on the morphology and functional adaptation of the residual small bowel in rat model of short bowel syndrome.

Methods: Twenty rats with 75% of the midjejunoileum removed were randomly divided into two groups, and received intra-peritoneal injection of GLP-2(250 micro*gd*kg-1*d-1) or subcutaneous injection saline(0.5 ml, twice one day) after operation.

Influence of glutamine on pancreatic blood flow and apoptosis of pancreatic acinar in rats with severe acute pancreatitis.

Objective: To investigate the role of glutamine on splanchnic blood flow, apoptosis of pancreatic acinar and the underlying mechanism in rats with severe acute pancreatitis.

Methods: Forty-eight rats were randomized into two groups: the glutamine group (n = 24) and the severe acute pancreatitis group (n = 24). Jejunotomy was performed in all rats: the glutamine group also received glutamine, and the severe acute pancreatitis group received normal saline.

[Effect of glutamine and growth hormone on adaptation in short bowel syndrome].

Objective: To assess the effects of parenteral glutamine and growth hormone supplementation on gut adaptation for patients with short bowel syndrome.

Methods: Twenty-six patients [male 15, female 11, aged (39 +/- 23) years] with short bowel syndrome received parenteral nutrition (PN) 3-52 months after surgical resection. The median length of remnant small intestine was 42.

[Prevalence of malnutrition in general surgical patients: evaluation of nutritional status and prognosis].

Objective: To estimate prevalence of malnutrition on admission to hospital and the relationship between nutritional status and prognosis.

Methods: Four thousand and twelve patients admitted to general surgery department were evaluated by a lot of nutrition indexes within 48 h. Operative morbidity and complications were recorded to identify the difference between malnourished and well-nourished patients.

Glutamine supplemented parenteral nutrition prevents intestinal ischemia- reperfusion injury in rats.

Aim: To examine whether glutamine prevents the injury to the intestinal mucosa after intestinal ischemia-reperfusion (I/R) in rats.

Methods: Thirty male Sprague-Dawley rats were randomly divided into 3 groups: a standard parenteral nutrition (PN) group (n = 10); an I/R-PN group (n = 10); an I/R-glutamine enriched PN (I/R-Gln) group (n = 10). The superior mesenteric artery (SMA) was clamped.

Effects of bowel rehabilitation and combined trophic therapy on intestinal adaptation in short bowel patients.

Aim: To evaluate the effects of bowel rehabilitation and combined trophic therapy on intestinal adaptation in short bowel patients.

Methods: Thirty-eight patients with severe short-bowel syndrome (SBS) were employed in the present study, whose average length of jejunum-ileum was 35.8+/-21.

The anabolic effects of recombinant human growth hormone and glutamine on parenterally fed, short bowel rats.

Aim: To evaluate the metabolic effects associated with administration of rhGH and/or Gln in parenterally fed, short-bowel rats.

Methods: Forty SD rats subjected to 75 % intestinal resection and maintained with parenteral nutrition were randomly divided into 4 groups as follows: -rhGH, -Gln; -rhGH, +Gln; +rhGH, -Gln; +rhGH, +Gln. Body weight and nitrogen balance were evaluated daily.

Human interleukin 10 gene therapy decreases the severity and mortality of lethal pancreatitis in rats.

Background: Studies have proven the validity of interleukin-10 (IL-10) in the treatment of experimental pancreatitis. Prophylactic human IL-10 (hIL-10) gene treatment attenuated the severity in cerulein models. Our research aims to study whether the therapeutic hIL-10 gene could decrease both severity and mortality in a lethal pancreatic model.
