Uterine leiomyosarcoma is an uncommon malignant neoplasm of smooth muscle origination and is associated with a poor prognosis. We report two cases of uterine leiomyosarcoma that presented with pulmonary metastases. 2-deoxy-2-(¹⁸F)fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) was performed to identify the primary carcinoma and found the focus located in the uterus. The follow-up magnetic resonance imaging (MRI) confirmed the diagnosis was uterine leiomyosarcoma.

Objective: To explore therapeutic effect of pitavastatin on young and middle-aged patients with hyperlipidemia complicated carotid plaques and its influence on vascular endothelial function. Methods: A total of 126 young and middle-aged patients with hyperlipidemia complicated carotid plaques [carotid intima-media thickness (IMT) ＞ 1. 5mm]were selected, and were randomly divided into no lipid lowering treatment group (n=62) and pitavastatin group (n=64). Flow-mediated dilation of brachial artery (FMD), carotid IMT and blood lipid levels before and 12 months after medication, and incidence rate of adverse events were recorded and compared between two groups. Results: Compare with before treatment and no lipid lowering treatment group after treatment, there was significant rise in FMD [(6. 70±2. 10) ％, (6. 60±2. 35) ％ vs. (8. 90±3. 60) ％], and significant reductions in levels of total cholesterol [(6. 05±1. 40) mmol/L, (5. 67±1. 90) mmol/L vs. (4. 05±1. 20) mmol/L], triglyceride [(2. 18± 0. 72) mmol/L, (2. 08±0. 68) mmol/L vs. (1. 77±0. 65) mmol/L]and low density lipoprotein cholesterol [(4. 65±1. 50) mmol/L, (4. 41±1. 36) mmol/L vs. (2. 01±1. 30) mmol/L]in pitavastatin group, P＜0. 05 or＜0. 01; there were no significant changes in IMT in two groups. No obvious adverse reaction was found in pitavastatin group. Conclusion: Pitavastatin can significantly improve lipid levels and vascular endothelial function in young and middle-aged patients with hyperlipidemia complicated carotid plaques.

Objective To study the effect of time and temperature on the count of peripheral blood cells in newborns.Methods The peripheral blood of 100 cases of newborns who were admitted in the First Affiliated Hospital of Hebei North University from January 2016 to June 2016 were collected,and measured with Sysmex XS-500i automatic blood cell analyzer immediately,then were split into two parts and stored at 4 ℃ and room temperature respectively.The measurement was repeated in 24 and 48 h,and the groups were compared on WBC,RBC,PLT,HGB,IG％ and IG#.Results There were statistically significant differences between the instantly measuring result and those in 24 and 48 h under room temperature (P＜0.05).In case of 4 ℃,the instantly measuring result had no obvious difference with that in 24 h (P＞0.05),while statistical difference with that in 48 h (P＜0.05).Conclusion Newborns' peripheral blood can be stored at 4 ℃C,and the counting results will not be affected for WBC,RBC,PLT,HGB,IG％ and IG# within 24 h.

OBJECTIVETo investigate the ideal digestive tract reconstruction methods among three different surgical methods after radical gastrectomy of gastric cancer patients.

METHODSA total of 123 patients who received elective radical gastrectomy for gastric cancer from February 2010 to August 2011 were prospectively enrolled and randomly divided into radical proximal gastrectomy and jejunal interposition group, radical proximal gastrectomy and esophageal with the posterior of residual-stomach group, and radical total gastrectomy and Roux-en-Y esophagojejunostomy group. Patients were followed up for 12 months. Symptoms of reflux esophagitis were observed, gastric emptying tests were done, liver and kidney function was also monitored. The quality of life was documented before operation, and one and twelve months after operation.

RESULTSNo significant differences were found among these three groups in the pH value of lower part of esophagus, the blood regular test results and the functional parameters of kidney and liver before and after operation(all P>0.05). Symptoms of reflux esophagitis was reported in 1(2.4%) patients in the jejunal interposition group, 10(24.4%) in esophageal with the posterial of residual-stomach group, and 7(17.1%) in the Roux-en-Y esophagojejunostomy group(P=0.017). There was 1(2.4%), 10(17.1%), and 8(19.5%) patients presented reflux of barium meal in these three groups, respectively (P=0.046). There were no statistically significant difference in PH at the distal esophagus(6.9±0.2 vs. 6.8±0.1 vs. 6.9±0.1, P=0.196). The quality of life was significantly improved one year after surgery in terms of general status, physical function, emotional function, fatigue, nausea/vomiting, pain, constipation, and diarrhea (all P<0.05), with the jejunal interposition superior than the other two methods.

CONCLUSIONThree methods of digestive tract reconstruction in radical gastrectomy of gastric cancer patients can improve the health status and the quality of life in gastric cancer patients. Radical proximal gastrectomy and jejunal interposition is the preferred method.

BACKGROUNDA monoclonal antibody would be an effective tool for the detection of circulating antigens in the serum of patients with schistosomiasis, but the traditional way of producing monoclonal antibodies is not cost-effective. The objective of this study was to find a new method for the large-scale production of monoclonal antibodies against Schistosoma japonicum (Sj).

METHODSA phage display antibody library for Sj was constructed. To obtain a single-chain variable fragment antibody (scFv) against Sj, the library was screened with metabolic antigens from adult Sj worms (Sj-MAg) using enzyme-linked immunosorbent assay. The soluble scFvs selected were used to detect Sj antigens in the serum of acute and chronic schistosomiasis patients.

RESULTSSix positive clones with good reactivity to Sj-MAg were obtained from the phage display antibody library of about 1.07 x 10(6) individual clones. Only two of these six clones bound specifically to Sj-MAg and were chosen for further analysis. Specific soluble anti-Sj-MAg scFvs were produced by inducing the 2 clones with isopropyl-D-thiogalactopyranoside. The characteristics of the scFvs were then determined. The results of Western blot showed that these scFvs could bind to Sj-MAg specifically and had a molecular weight of about 31 kD. When testing serum from schistosomiasis patients with one of the two specific scFvs, its sensitivity was found to be 60% and 37% in acute and chronic patients, respectively, with a specificity of 90%. When the two specific scFvs were combined, their sensitivity was found to be 75% and 57% in acute and chronic patients, respectively, with a specificity of 85%.

CONCLUSIONSThe results indicate that the scFvs are potentially useful for the diagnosis of schistosomiasis. The library construction also provides a useful tool for the further screening of other antibodies for both diagnostic and immunotherapeutic applications and for epitope analysis and vaccine design.
