Objective To summarize the characteristics on diagnosis and therapy of adult diaphragmatic eventration. Method The clinical data of 26 patients with adult diaphragmatic eventration, hospitalized in General Hospital of PLA from 1988 to 2009, were retrospectively analyzed. The 26 patients, 14 males and 12 females, were aged from 26 to 66 (mean 44.0?5.7), with disease course of 8 months to 17 years. Among them 25 suffered from left and 1 from right diaphragmatic eventration; 24 with total and 2 with localized diaphragmatic eventration; of them 2 without symptoms were detected in physical examination, and among the 24 remainders 18 were with the symptoms of thoracic discomfort after eating, 8 with dyspnea after activities, 14 with hiccup, vomiting and abdominal discomfort. Most of the patients had more than one symptom. All patients received operations via the chest cavity under general anesthesia, 24 cases were performed by double mattress suture with diaphragm discission, while 2 cases by fold suture without diaphragm discission. Results Symptoms relief was reported in 24 patients at the early stage after operation. Eighteen patients were followed up for one year, and 15 of them received chest radiograph, among whom the normal diaphragm localization were in 13 cases and relatively higher diaphragm localization in 2 cases, while the other 3 patients received no re-examination of chest radiograph. Among the 18 cases receiving one year of follow-up, 10 cases got complete disappearance of symptoms, 6 cases got symptoms relieved or partially disappeared, and 2 patients got symptom relapsed. Conclusion Surgical outcome, especially the double mattress suture is satisfactory for adult diaphragmatic eventration.

Objective To investigate the expression of LRP16 gene in lung cancer, and explore its clinicopathological significance. Methods Fresh resected tissues from 54 patients with primary lung cancer were collected and the clinicopathological data were gathered. The expression of LRP16 protein in cancer tissues and the matched normal tissues were determined by Western blotting, and the relationship between LRP16 expression and clinicopathological data was analyzed. It was defined as overexpression when the LRP16 expression of cancer tissues was twice or more higher than that of matched normal tissues. Results The LRP16 was overexpressed in 15 out of 54 patients with lung cancer (27.8%). Among the 23 patients with adencarcinoma, the overexpression of LRP16 was found in 11 cases (47.8%), while in the patients with squamous carcinoma, the overexpression of LRP16 was only found in 4 out of 27 cases (14.8%), and there was a significant difference between the two groups (Pearson test, P=0.0258). Besides, very low expression or non-expression of LRP16 was found in 2 large cell lung cancer and 2 small cell lung cancer. The overexpression rate of LRP16 was 20.0% (2/10) in tumor with diameter less than 3cm and 29.5% (13/44) in tumor with diameter ≥3cm, and there was no significant difference between the two groups (Pearson test, P=0.7224). Conclusions There were significant differences of LRP16 overexpression in cases of adencarcinoma or squamous carcinoma with or without lymphatic metastasis. It is suggested that LRP16 is a tumor-related gene of lung cancer, and may play an important role in molecular staging of lung cancer.

BACKGROUND:Studies have shown that chitosan and other natural polysaccharides have heparin-like anticoagulant function after sulfonated modification. Sulfonated chitosan has good anticoagulant property because the sulfonate group formed by sulfonated chitosan is similar with the active group of heparin. OBJECTIVE: To prepare the anticoagulant chitosan nanoparticles and to detect its morphology, physical and chemical properties and biological security. METHODS: Chitosan nanoparticles were synthesized by emulsion-chemical cross link. Sulfonated chitosan nanoparticles were synthesized by sulfonation reaction. Its morphology was described by transmission electron microscope. The peak-value change of its specific groups was observed by infrared spectroscopy. (1) Coagulation experiment: Heparin, chitosan nanoparticles and 10, 30 and 50 mg of sulfonated chitosan nanoparticles were added into the blood of Spraque-Dawley rats. The coagulation indicators were detected. (2) Hemolysis experiment: deionized water, physiological saline and 10, 30, 50 g/L sulfonated chitosan nanoparticles extracts were added into 2% red blood cel suspension of rabbits. The hemolysis rate was detected. (3) Cytotoxicity experiments: DMEM medium containing fetal bovine serum and 10, 30, 50 g/L sulfonated chitosan nanoparticle extracts were used to culture human umbilical vein endothelial cels. Cel relative growth rate and toxicity grading were detected after 72 hours. RESULTS AND CONCLUSION: Scanning electron microscopy showed that sulfonated chitosan nanoparticles had good morphology, with a diameter of 50 nm. Infrared spectroscopy showed that the sulfonated replacement occurred.In vitro coagulation experiments showed that sulfonated chitosan nanoparticles had significant anticoagulant effects in a dose-dependent manner. Sulfonated chitosan nanoparticles meet the national safety standard for hemolysis rate of less than 5%, non-induced hemolysis property. Cytotoxicity assays showed that sulfonated chitosan nanoparticles extracts had no significant cytotoxicity, and its biological safety was in line with the national standards.

The effects of cyclosporine A (CsA) on glucose metabolism and betancell functions in vivo in rats were investigated. CsA (20mg/kg, 2/d) was given to Spraguer-Dawley rats for 14d. After a 1.5g/kg body weight glucose load by gavage the plasma glucose at 1 h and the area under curve (AUC) of plasma glucose were higher in the CsA-treated group than in the control (P

Objective To investigate the effect of patient positioning on the Duplex ultrasound evaluation of great saphenous vein reflux elicited by the pneumatic cuff method. Methods FFifty great saphenous veins (GSV) with relfux (relfux group) and iffteen with no prior history of venous disease (healthy group) were examined by duplex scanning in the supine, 20 degrees reverse-trendelenburg (RT-20), 40 degrees reverse-trendelenburg (RT-40) and standing position. Each GSV was assessed for relfux at three venous sites:two centimeter below the sapheno-femoral junction (SFJ), the greater saphenous vein in the mid thigh (MGV) and the greater saphenous vein in the upper calf (CGV). Pneumatic cuff compression pressure of conifned 100 mmHg (1 mmHg=0.133 kPa) was used onto the calf to elicit relfux. The incidence of positive venous relfux was calculated. The statistical differences of the peak relfux velocity and duration of relfux in four positions were analyzed. Results TThe relfux elicited in the standing position was set as the gold standard. In healthy group, there was no false positive results of relfux in supine, RT-20 and RT-40 positions. In relfux group, false negative results were found at all venous sites when limbs were examined in supine position [false negative rate:59%(19/32), 22%(11/50), 24%(12/50)]. At RT-20 and RT-40 positions, the incidence of venous relfux reached 100% at MGV and CGV, and false negative cases were only detected at SFJ [false negative rate:12%(4/32), 12%(4/32)]. The relfux time in standing, supine, RT-20 and RT-40 positions were (7.75±3.23) s, (5.27±3.66) s, (8.67±3.72) s, (8.55±3.93) s respectively. There were signiifcant differences among different positions in reflux time (F=56.9, P<0.01). In detail, no significant differences were identified between standing position and RT-20 or RT-40 position (q=1.51, 1.33 respectively, both P > 0.05), except for supine position (q=4.11, P<0.01). Peak relfux velocity in standing, supine, RT-20 and RT-40 positions were (55.26±22.24) cm/s, (22.87±12.03) cm/s, (38.46±16.30) cm/s, (45.13±19.21) cm/s respectively. There were also signiifcant differences among different positions in peak relfux velocity (F=13.7, P<0.01). Comparing the supine, RT-20 and RT-40 positions with standing position, differences of the peak relfux velocity between them were all statistically signiifcant (q=12.71, 6.59, 3.98 respectively, all P<0.01). Conclusions When GSV reflux was examined by pneumatic cuff compression, false negative rate was higher in the supine position. RT-20 and RT-40 position were effective to detect GSV relfux, espically for GSV at mid-thigh and upper calf.
