Objective To observe serum and callus leptin expression in rats model with fracture and traumatic spinal cord injury (SCI). Methods 72 male SD rats were randomized equally into 4 groups: control, SCI group, fracture group, and fracture/SCI group. Rats were sacrificed at 7, 14, 21 and 28 days after fracture/SCI. Serum leptin was detected by radioimmunoassayat 1, 7, 14, 21 and 28 days, and callus formation was measured radiologically at 14, 21 and 28 days. Callus leptin was analyzed with immunohistochemistry. Results Serum leptin in the fracture group, SCI group and combined fracture/SCI group were all higher than in control group at the 1, 7, 14 and 21 day time-point (P < 0.05). Serum leptin in the combined fracture/SCI group was significantly higher than the fracture group at 7, 14 and 21 days (P < 0.05), and higher than SCI groups at 14 and 21 days after operation (P < 0.05). The percentage of leptin-positive cells in the fracture/SCI callus, and callus volume was significantly higher than the fracture-only group (P < 0.001). Conclusions Leptin expression increases in the recovery process after SCI, and the recovery of fracture becomes sooner.

Objective To investigate the correlation between TCF7L2 gene rs3814570 polymorphisms with type 2 diabetes mellitus(T2DM) in Uygur population of Xinjiang area.Methods By adopting the case-control study design,949 cases of T2DM were recruited as the observation group and 963 individuals Undergoing healthy physical examination were selected as the control group.The TCF7L2 gene polymorphism was detected by matrix-assisted laser desorption/ionization-time of flight(MALDI-TOF).Results The statistical differences in frequencies of CC,CT and TT genotypes and the C and T allele frequencies on TCF7L2 rs3814570 were found between the T2DM group and control group(P＜0.05).The risk of suffering from T2DM in the carriers of CT genotype was 0.331 times of that in the carriers of CC genotype(OR =0.331,95 ％ CI:0.166-0.661,P =0.002),the risk of suffering from T2DM in the carriers of TT genotype was 0.539 times of that in the carriers of CC genotype(OR=0.539,95％CI:0.348-0.834,P=0.005),and the risk of suffering from T2DM in the carriers of T allele was 0.501 times of that in the carriers of C allele(OR=0.501,95 ％ CI:0.377-0.664,P＜ 0.01).Among all subjects,the FPG level of the CT + TT genotype group on TCF7L2 gene rs3814570 locus was significantly lower than that of the CC genotype group(P＜0.05).Conclusion The rs3814570 locus in TCF7L2 gene may be associated with T2DM occurrence in Uygur population of Xinjiang area,the T allele and TT genotype might be protective factors of T2DM.

[ABSTRACT]AIM:ToinvestigatetheeffectofD4F,anapolipoproteinA-Imimeticpeptide,onoxidizedlow-density lipoprotein ( ox-LDL)-induced macrophage apoptosis and activation of caspase-12, a key molecule in endoplasmic reticulum stress ( ERS )-associated apoptotic pathway, and to elucidate the underlying molecular mechanisms. METHODS:RAW264.7 macrophages were pretreated with D4F (12.5, 25 and 50 mg/L), 4-phenylbutyric acid (PBA, 5 mmol/L) or diphenyleneiodonium ( DPI, 5 μmol/L) for 1 h and then treated with ox-LDL (100 mg/L) or tunicamycin ( TM, 4 mg/L) for 24 h.The cell viability and apoptosis were determined by MTT assay and TUNEL detection, respective-ly.The levels of malondialdehyde ( MDA) and reactive oxygen species ( ROS) in the cells and the activities of superoxide dismutase ( SOD) and nicotinamide adenine dinucleotide phosphate ( NADPH) oxidase were determined.The protein level of caspase-12 was examined by Western blot analysis.RESULTS: Similar to the ERS inhibitor PBA, D4F protected RAW264.7 macrophages from ox-LDL or TM ( an ERS inducer)-induced decrease in the viability and increase in apoptotic rate in a dose-dependent manner.Like DPI (an oxidative stress inhibitor), D4F significantly inhibited ox-LDL-induced ox-idative stress, as expressed by the decreased generation of ROS and MDA ( P<0.01) , the increased activity of SOD and the decreased activity of NADPH oxidase (P<0.05).Moreover, similar to PBA and DPI, D4F significantly suppressed ox-LDL-induced activation of caspase-12 in a concentration-dependent manner ( P<0.05) .Furthermore, D4F also inhibi-ted the caspase-12 activation induced by TM (P<0.05).CONCLUSION: D4F inhibits macrophage apoptosis induced by ox-LDL, and the mechanism is at least partially by reducing oxidative stress and inhibiting the activation of caspase-12.

Objective To explore the application effect of postural animation video instruction mode in elderly patients undergoing epidural anesthesia. Methods A total of 300 patients with epidural anesthesia were registered from January 2015 to February 2016. The patients were divided into trial group and control group with 150 cases each. The trial group was preoperatively interviewed by the postural anatomy video instruction mode, and the control group was only preoperatively interviewed by oral interpretation. The epidural anesthesia effect and anxiety between the two groups were compared. Results The difference of anesthesia posture and anatomical position, the average time of epidural puncture, the success rate of one puncture and the degree of anxiety before and after mission were 90.67% (136/150), (14.50 ± 10.20) s, (425.60 ± 78.30) s, 97.33% (146/150) and (21.65 ± 6.62) points respectively. The control group was 22.00%(33/150), (112.60 ± 60.80) s, (589.40 ± 90.70)s, 82.67%(124/150) and (6.65 ± 5.40) points respectively. There were significant differences between the two groups (χ2=8.79, t=13.54-19.88, all P < 0.01). Conclusions The postural anatomical video teaching mode can relieve anxiety, improve the degree of fit of epidural anesthesia and the success rate of puncture, shorten the time of posture, thus shorten the average time of epidural puncture, improve the quality of nursing in the operating room, work efficiency.

OBJECTIVETo evaluate the efficacy of minocycline as an adjunct to scaling and root planning (SRP) in treating chronic periodontitis.

METHODS64 male smokers with moderate to advanced periodontitis were randomly divided into two groups: SRP alone (SRP) and SRP plus minocycline (SRP+M). All clinical parameters including plaque index (Pll), gingival index (GI), bleeding on probing (BOP), probing depth (PD) and attachment gain were recorded at baseline, 3 and 6 months after treatment.

RESULTSAccording to PlI, GI and BOP, there was no significant difference between the two groups at 3 and 6 months after periodontal therapy (1 > 0.05). However, PD reduction and attachment gain were significantly greater for SRP+M than that for SRP (P < 0.05). For SRP+M and SRP groups, PD reduction were 1.98 mm and 1.32 mm, and attachment gain were 1.87 mm and 1.14 mm respectively. Deep pockets in SRP+M group showed more obvious PD reduction (3.48 mm versus 2.21 mm, P < 0.01) and attachment gain (2.62 mm versus 1.23 zmm, P < 0.01) than that in SRP group.

CONCLUSIONTreatment with SRP plus locally delivered minocycline is more effective than SRP alone in male smokers with chronic periodontitis. Mechanical debridement plus locally delivered antibiotics are recommended especially for smokers with deep pocket periodontitis.
