Sleep plays an important role in the modulation of endocrine function and energy metabolism;hormone levels are markedly different during a sleepless night compared with a night of normal sleep.Sleep deprivation may change the levels of cortisol,growth hormone(GH)and thyrotropin(TSH)at night.In addition,sleep curtailment disturbs the balance of anorexi- genic(leptin)and orexigenic(ghrelin)factors,and does harmful to glucose tolerance.

Objective To test the predicative roles of neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1( KIM-1 ) for acute kidney injury (AKI) in critically ill patients. Methods Children from pediatric intensive care unit, were randomly divided into four groups:critically ill patients with AKI (group 1 ), critically ill patients with non-AKI (group 2) , chronic kidney disease group (group 3), healthy control group (group 4). 1.5 ml venous blood and urine specimens were collected and kept under-70°C. Serum creatinine , urine NGAL and urine KIM-1 were analyzed. Results Compared with group 2, group 3 and group 4, the urine NGAL and urine KIM-1 increases obviously in group 1 (P<0.05). There is no signiifcance of urine NGAL and urine KIM-1 between group2, group3 and group 4 (P>0.05). The concentration of urine NGAL increased more than 10 times of base-line level 2 days before the diagnosis of AKI under the Acute Kidney Injury Network standard with area under curve (AUC) 0.955 (P<0.05) , and the concentration of urine KIM-1 increased more than 5 times of base-line level 1 day before AKI with AUC 0.878 (P<0.05). The AUC was 0.984 (P<0.01) when they were combined. There is negative correlation between the increased times of urinary KIM-1, urinary NGAL and vally value of creatin clearance rate. Conclusions The concentrations of urine NGAL and urine KIM-1 are useful early biomarkers for predicting AKI, especially when they were combined.

Objective:To evaluate the influence of platelet-rich plasma(PRP) on periodontal healing of replanted teeth in 6 Beagle dogs.Methods:The second incisors were pulled out and re-implanted after 60 min dry storage.In group A,PRP were applied before replantation,and 7days later the teeth received root canal treatment.In group B,PRP were applied before replantation either,but without root canal treatment.In group C,PRP were not applied and 7 days later,the teeth received root canal treatment.In group D,no PRP were applied and no root canal treatment.All the dogs were sacrificed after 12 weeks and the histological parameters were observed.Results:There were no significant differences between group A and C.Group B showed a lower incidence of ankylosis,and higher incidence of healed PDL compared with group D.Conclusion:Under the definite condition,PRP can help to decrease the incidence of ankylosis and increase the incidence of healed PDL in groups that the pulps were not removed.

BACKGROUND: Studies have demonstrated that exogenous basic fibroblast growth factor (bFGF) has intensive effects to promote proliferation of gingival fibroblasts (GFs) cultured in vitro and the heeling of gingival wounds. OBJECTIVE: To investigate the effects of bFGF gene transfection on the biological performance of Beagle canine GFs. DESIGN, TIME AND SETTING: An observation and comparison in vitro experiment regarding cells was accomplished in Centre of Cell Biology and Development of Fujian Medical University and Department of Comparative Medicine in Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA from April to September of 2008. MATERIALS: Four beagle dogs, male, 12 months old, weighing 10-13 kg were used in this experiment, plRES2-EGFP-bFGF plasmid containing full-length human bFGF gene cDNA was constructed and conserved by our institution. METHODS: Free gingiva of the 2nd, 3rd and 4th premolars were excised from left upper jaw of Beagle dogs, dnsed with aseptic phosphate buffer four times, then cut into pieces and digested with 2.5 g/L pancreetin for 2 hours at 37 ℃. After the cantrifugation and supernatant removal, DMEM containing 10% fetal bovine serum was added to incubate on 6-well plate with coverlips in 5% CO2 incubator at 37 ℃. Logadthrnically growing cells were digested and passaged. GFs were transfected with pIRES2-EGFP-bFGF plasmid using liposome mediated method, while vacant plasmid transfection and un-transfection group served as controls.MAIN OUTCOME MEASURES: Proliferation and apoptosis feature of the GFs were evaluated by M'rE and AOEB, respectively. The activity of alkaline phosphatase was assayed by chemical coledmetry. RESULTS: All of three groups cells entered log phrase on three days after transfection. MTT results showed that the proliferation of GFs transfected with bFGF was greater than cells transfected with vacant vector and untransfected cells (P < 0.05). AO/EB dyeing showed the apoptosis rate of GFs transfected with bFGF was reduced compared with other two groups (P < 0.05). After bGFG gene transfection, the ALP activity remained unchanged and there was no significant difference compared with untransfected cells.CONCLUSION: The transfection of bFGF gene to GFs can promote the proliferation of GFs and depress the apoptosis. No promotion is present with regard to the GFs differentiation.

Objective:To optimize and improve the content determination method for nitroglycerin ointment. Methods:An HPLC method was used,the column was Hypersil ODS(150 mm × 4. 6 mm,5 μm),the mobile phase was acetonitrile ∶water(50 ∶50),the detection wavelength was set at 220 nm,the flow rate was 1 ml·min-1 ,the column temperature was 30℃,and the injection volume was 20 μl. Results: The results showed a good linear relationship within the concentration range of 0. 020 3-0. 203 3 mg · ml-1 ( r =0. 999 9),and the average recovery was 99. 51%(RSD=1. 06%,n=9). Conclusion: The method is rapid,accurate and reproduci-ble,and can be used to determine the content of nitroglycerin in nitroglycerin ointment.

Objective To study the prevalence of thrombocytosis in patients with non-small-cell lung cancer (NSCLC) and its correlation with clinicopathological features.Methods 156 patients with advanced NSCLC were retrospectively analyzed.The platelets degree between the groups with different sex,age,smoking,histological type of advanced NSCLC was compared and analyzed statistically.The relationship between the platelet count and chemotherapy effects was analyzed.Single analysis and Cox regression analysis were used for TTP and OS.Results Compared with the healthy persons,Plt significantly elevated in group with advanced NSCLC (36.5 ％,57/156 vs 5.0 ％,5/100) (P ＜ 0.01),and thrombocytosis group responded poorly to chemotherapy (22.8 ％,13/57 vs 39.4 ％,39/99) (P ＜ 0.05).The TTP (3.0 months vs 5.2 months) and OS (11.2 months vs 14.2 months) of Plt elevated group were significantly shorter than those of normal group.Conclusion Thrombocytosis is closely related to progress and metastasis of advanced NSCLC.Platelet count can be used as an assistant index in the prognosis judgment of patients with advanced NSCLC.

Sleep is a common physiological phenomenon of animals.We may have different kinds of sleep disorders in our daily life,such as difficulty falling asleep,insomnia,hypersomnia and changes of sleep patterns,etc.Pain is a subjective response of the body to stimuli of certain degrees.Sleep disorders are closely related to pain:pain can interfere with people's normal physiology and psychology conditions and affect individual's sleep;different kinds of sleep disorders can affect the body' s sensitivity to pain.The relationship between pain and sleep disorders has become one of the most common causality in clinical research.In this paper we summarizes the pathophysiological relation and mutual influence between pain and sleep disorders.
