Objective To investigate the alteration of serum ghrelin and leptin in patients with functional dyspepsia (FD) and their clinical significance. Methods Sixty patients with FD [-30 patients with postprandial distress syndrome(PDS) and 30 patinets with epigastric pain syndrome(EPS)] were enrolled. Thirty healthy subjects were severed as controls. The serum ghrelin and leptin were measured by enzyme linked immunosorbent assay and radioimmunosorbent assay, respectively. Results The concentrations of serum ghrelin and leptin were both significantly lower in patients with FD than in controls (P<0.01). Meanwhile, the concentrations of serum ghrelin and leptin in PDS patients were significantly lower compared with controls (P<0.01) and EPS patients (P<0.01). There was no significant difference in levels of serum ghrelin and leptin between controls and EPS patients(P>0.05). Conclusions The alterations of serum ghrelin and leptin in PDS patients are responsible for their reduction in FD patients. The PDS may he associated with abnormalities in gastrointestinal motility. There is an interaction between serum ghrelin and leptin in development of FD. The detection of serum ghrelin or leptin is helpful in classification and treatment of FD.

Radiation-induced lung injury (RILI) is a common complication in thoracic cancer patients through radiotherapy, which can be divided into the early-stage radiation-induced pneumonitis (RP) and late-stage radiation-induced lung fibrosis (RILF). At present, glucocorticoids are mainly adopted in the clinical treatment of RP. However, there has been no effective medical treatment for RILF. RILF patients will eventually die from respiratory failure. The exact mechanism of RILI remains unclear. Current studies have proposed that its possible pathogenesis might consist of genetic heterogeneity, oxidative stress and cell damage. In this review, studies related to the pathogenesis of RILI were summarized.

Objective To evaluate transport efficiency and safety by process management during the handover of patients with tracheal intubation post-operation. Methods Prospective studies were performed between patients with or without process management during the handover. The time of handover were recorded and compared. The difference between systolic and diastolic blood pressure, heart rate, and arterial oxygen saturation were also recorded and compared. The adverse events during the handover were also investigated. Results It costed less time in the handover of patients under process management with significant difference[(4.75±0.54) min vs. (7.05±0.88) min, t=-17.21, P<0.01]. The incidence rate of harmful cases in the handover of patients under process management was significantly declined than that without process management[ 1.67%(1/60) vs. 13.33%(8/60),Χ2=4.324 3,P<0.05 ]. Conclusions Process management may facilitate the handover of patients with tracheal intubation post-operation and improve its safety.

Background Scarring of the filtering bleb is a main cause of filtering surgical failure in glaucoma.It has been reposed that tetrandrine could suppress the proliferation of cultured human fibroblast of Tenons capsule in vitro and thus has the potential effect to prevent scarring after the filtering surgery. Objective Present study was to investigate the anti-cicatricial effect of tetrandrine drug delivery system(Tet DDS)during filtration surgery. Methods Filtration surgery was performed in bilateral eyes of 18 New Zealand white rabbits.The Tet DDS with 0.3 mg Tet,0.2 mg Tet or free-Tet were implanted subcunjunctially during the surgery.The filtering blebs were scored in 1 day,4,7,10,14 days after referring to the corneal thickness and bleb range under the slit-lamp biomicroscopy.The morphology of filtering bleb was assessed by in vivo confocal microscopy in 7 and 14 days after operation.The filtering bleb specimen was prepared in 7 and 14 days for the histopathological examination. Results The filtering bleb scores in Tet DDS implantation groups were significantly higher than those in free-Tet DDS group from 4 days through 14 days after trabeculectomy(P＜0.01),and the scores showed a considerably increase in 0.3 mg Tet DDS group compared with 0.2 mg Tet DDS group from 7 days through 14 days after trabeculectomy(P＜0.05).The filtering blebs of Tet DDS implantation groups were found with distinct subepithelial cystic spaces under the light microscopy and in vivo confocal microscopy on the 7th day and 14th day after surgery.Compared with free-Tet DDS group,the numbers of subepithelial mierocysts were much more(P＜0.01)and the area of microcysts was larger(P＜0.01)in Tet DDS group.The filtering tissue presented with more subepithelial microcysts and larger microcysts range in 0.3 mg Tet DDS group than 0.2 mg Tet DDS group in 7 and 14 days after operation(P＜0.05).The inflammatory cell infiltration wag milder in 0.3 mg Tet DDS group in comparison with 0.2 mg Tet DDS group and free-Ted DDS group.Conclusion Tet DDS has strong inhibitory effects on inflammatory cells activity and fibroblagt activity the early stage after filtering surgery and therefore improve the surgery success rate.

Objective:To develop an HPLC method for determining the total ginkgo flavonoid in self-emulsifying drug delivery sys-tem. Methods:Effective chromatographic separation was achieved using a phenomenex C18 column (250 mm × 4. 6 mm, 5 μm) with a mobile phase composed of methanol and water (0.4% phosphoric acid) with the ratio of 50 ∶50 (v/v). The mobile phase was pumped using an isocratic HPLC system at a flow rate of 1. 0 ml·min-1 , the detection wavelength was 360 nm and the column temper-ature was 30 ℃. Results:The three components in the total ginkgo flavonoid were well separated by the proposed method. The linear relationship between the peak area and the concentration was promising within the range of 2. 0-40. 0 μg·ml-1 for quercetin, 3. 0-60. 0 μg·ml-1 for kaempferide and 2. 0-40. 0 μg·ml-1 for isorhamnetin. The mean recovery of quercetin, kaempferide and isorham-netin was 98. 4%, 99. 7% and 100. 5% with RSD of 0. 92%,0. 62% and 1. 24% (n=9), respectively. Conclusion:The method is specific and stable in the determination of total ginkgo flavonoid in self-emulsifying drug delivery system.

Objective:To prepare total ginkgo flavonoid self-emulsifying drug delivery system(TGF-SMDDS)and estimate its char-acteristics in vitro. Methods:The formula of TGF-SMDDS was optimized based on the solubility tests,formula compatibility and microe-mulsion area in the pseudo ternary phase diagram. The appearance,morphology,particle size,zeta potential and in vitro dissolution of TGF-SMDDS were investigated. Results:The formula was composed of oleoyl macrogolglycerides as the oil phase,Tween-80 as the sur-factant and XCF as the co-surfactant. The ratio of oil phase,surfactant and co-surfactant was 10 ∶ 6 ∶ 4. The drug loading was 10. 0 mg· g -1 . After mixed with water,TGF-SMDDS was formed a clear and transparent microemulsion with homogeneous small spheres as seen un-der a transmission electron microscope. The particle size and zeta potential of TGF-SMDDS was(87. 4 ±26. 7)nm and( -13. 1 ±1. 5) mV,respectively. The accumulative dissolution of TGF-SMDDS in pH1. 2 hydrochloric acid solution was(96. 1 ±4. 8)% in 45 min. Con-clusion:The TGF-SMDDS can significantly enhance the dissolution of TGF in vitro,which may be a potential effective preparation for TGF.

Objective To investigate the potential change of cellular cholesterol efflux and the functional changes of ABCA1 on macrophages from diabetes animals. Methods High energy diet was given to golden hamster to make animal model of hyperlipidemia. Diabetes was induced by a single intraperitoneal injection of STZ (30 mg/kg). Macrophages were isolated and incubated with apoA-I or 8-br-cAMP in vitro. Cellular cholesterol content was measureal before and after treatment by HPLC. Results Intracellular cholesterol content of diabetic animals was higher than that in high energy diet and normal controls. Expression of ABCA1 mRNA was upregulated in diabetic group after incubation with apoA-I and cAMP. When macrophages were incubated with apoA-I, cholesterol efflux increased with the prolongation of incubation time.The amount of intracellular cholesterol efflux in 3 groups of animals showed the following relationship: diabetic animals exceed high energy diet fed animals, and the latter exceeds normal animals. Conclusion Intracellular lipid efflux depends mainly on the presence of extracellular apoA1 as well as membrane ABCA1 protein. The deposition of cholesterol in the macrophage of diabetic and insulin resistant animals may be related to the characteristic changes of quantity and function of apoA1 in these animals.
