Body iron store is one of the important aspects of the iron status in a population. According to the model established by Cook and Finch, the iron stores of 254 middle-aged Chinese women were estimated. The median of iron stores was calculated to be -282 mg with the 5th percentile of -630 mg and the 95th percentile of 32 mg respectively. The risk factors of iron deficiency in these middle-aged women were menorrhagia (RR 4.55), application of intrauterine device (RR 1.88), history of blood loss (RR 1.65), and chronic gastrointestinal diseases (RR 0.84). The key point of the application of the Cook's model was discussed.

Bipolar disorder(BD)is a serious mood disorder with high prevalence,morbidity and mortality rates. Glycogen synthase kinase-3β(GSK-3β) is a multifunctional serine/threonine protein kinase that is generally located in eukaryotic cells with such functions as the adjustment of the synthe?sis of glycogen metabolism,cell proliferation and differentiation and gene expression. It is involved in multiple signaling pathways and regulates cell signaling proteins,structural proteins and transcription factors through phosphorylation,affecting the survival of the neurons and plasticity. According to gene poly?morphism and clinical studies,GSK-3β may be associated with BD. As a GSK-3β inhibitor,lithium is an effective BD therapeutic drug,and the small molecule inhibitor targeting GSK-3βis also a hotspot of BD treatment. GSK-3βmay be a potential target in the treatment of BD.

ObjectiveTo investigate the clinical effect of entecavir combined with antituberculosis therapy in patients with tuberculosis complicated by chronic HBV infection. MethodsA total of 108 patients with tuberculosis complicated by chronic HBV infection were divided into entecavir group with 58 patients and control group with 50 patients. The patients in the entecavir group were given entecavir from 1 month before antituberculosis therapy to the end of antituberculosis therapy, and those in the control group were given antitubercular agent alone. The incidence of liver injury and clinical symptoms, time to appearance of abnormal liver function, and time to liver function recovery were compared between the two groups. The two-independent-samples t test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data between groups. ResultsCompared with the control group, the entecavir group had significantly higher incidence rates of abnormal liver function (29.31% vs 64.00%, χ2=8.475, P＜0.05) and clinical symptoms of liver injury (17.24% vs 28.00%, χ2=5.534, P＜0.05). There were significant differences in the time to appearance of abnormal liver function (25.1±10.2 d vs 20.1±8.9 d, t=2.675, P＜0.05) and time to liver function recovery (26.5±9.8 d vs 32.6±11.2 d, t=3.778, P＜0.05). ConclusionEntecavir can significantly reduce the incidence of liver injury caused by antituberculosis therapy, postpone the time to appearance of liver injury, and accelerate liver function recovery in patients with tuberculosis complicated by chronic HBV infection.

Objective To compare the rates of successful intubation between light-stylet and adjustable McCoy laryngoscope for the management of difficult airway with active oral bleeding. Method Thirty casualties traumatized with active oral bleeding were enrolled after failure of endotracheal intubation tried twice by an attending doctor with Macintosh laryngoscope. The patients were randomly( random number) divided into light-stylet (LS)group and McCoy laryngoscope(MC) group ( n = 15 in each group). The rate of successful intubation and the time consumed for intubation were recorded. Results The rate of successful intubation at the first attempt and the total rate of successful intubation in LS group were higher than those in MC group (14/15 vs. 6/15, P =0.005, 15/15 vs. 9/15, P =0.017, respectively). The time consumed for intubation was less in LS group than that in MC group (24 seconds in average,ranged from 23 ～ 34 seconds vs 48 seconds in average, ranged from 31 ～ 119 seconds, P =0.011). Conclusions The light-stylet is a novel tool for intubation in casualties with difficult airway and active oral bleeding with high success rate.

OBJECTIVE Toexploretheantidepressanteffectsofalbiflorinandtheinvolvementof hypothalamic-pituitary-adrenocortical (HPA) axis function in its antidepressant potency.METHODS Two weeks after the olfactory bulbectomized (OB)surgery,albiflorin (2.5 ,5.0 ,10.0 mg·kg -1 ,ig) and imipramine 5.0 mg·kg -1 (ig)were given to rats twice a day for 14 d.The open-field test was con-ducted to evaluate the move ment distance,move ment ti me and velocity of olfactory bulbecto mized rats and sham-operated rats.The serum levels of corticosterone(CORT)and adrenocorticotropic hormone (ACTH)in rats were measured by the enzyme linked immunosorbent assay.The expression levels of glucocorticoids receptor (GR)in the hippocampus of the rats were analyzed using Western blot proce-dures.RESULTS Comparedwithsham-operatedrats,movementdistance,movementtimeandveloci-ty of the OB rats were significantly increased (P<0.01 ).Albiflorin 1 0.0 mg·kg -1 significantly reduced the movement distance,movement time and velocity of OB rats (P<0.05)after being given for 7 d. The movement properties were significantly reduced by albiflorin 5.0 and 10.0 mg·kg -1 when given for 14 d (P<0.05).The OB rats demonstrated significantly increased levels of serum CORT and ACTH (P<0.01 )and decreased GR expression in the hippocampus (P<0.01 ).Albiflorin 2.5,5.0 and 10.0 mg·kg -1 significantly reduced the serum CORT and ACTH levels (P<0.05),while albiflorin 5.0 and10.0mg·kg-1increasedtheexpressionofhippocampalGR(P<0.05).CONCLUSION Albiflorin may have re markable behavioral antidepressant effects on olfactory rats and one of the related mecha-nis ms may be its regulation of the hyperactivity of HPA axis function.

ObjectiveTo investigate the effects of spleen-Yin deficiency on gastrointestinal absorption， water metabolism and intestinal flora in rats with spleen-Yin deficiency syndrome. MethodA rat model of spleen-Yin deficiency syndrome was established by using the composite factors， including irregular meat and vegetable diet， weight-bearing fatigue swimming and gavage with warm-heat injury-Yin drugs. The changes of body weight， food intake， water intake and duration of swimming in the blank and model groups were observed. Hematoxylin-eosin（HE） staining was used to observe the histopathological damage of the stomach and colon. Urinary excretion rate of D-xylose was determined by phloroglucinol method. The content of gastrin（GAS） in serum was determined by enzyme-linked immunosorbent assay（ELISA）. The relative expression levels of vasoactive intestinal peptide（VIP）， aquaporin 3（AQP3） and AQP4 in gastric tissues were detected by Western blot. The relative mRNA expression levels of VIP， AQP3 and AQP4 in gastric tissues were detected by Real-time fluorescence quantitative polymerase chain reaction（Real-time PCR）， and the changes of intestinal flora were analyzed by 16S rDNA sequencing. ResultCompared with the blank group， the results of general physical signs showed that the body weight and food intake of rats in the model group were significantly decreased， the water intake was significantly increased（P<0.05， P<0.01）， and the duration of swimming was significantly decreased（P<0.01）. Pathological examination results showed that in the mucosa of gastric tissues of rats in the model group appeared to be misaligned， the mucosa of colonic tissues could be seen to be obviously thinned or mutilated， and the epithelial cells appeared to be necrotic or even exfoliated. Compared with the blank group， the urinary D-xylose excretion rate of rats in the model group was significantly decreased（P<0.01）， and the serum GAS content was significantly decreased（P<0.05）. Compared with the blank group， Western blot results showed that the relative expression level of VIP protein in gastric tissues of rats in the model group was significantly decreased， while the relative expression levels of AQP4 and AQP3 proteins were significantly increased（P<0.01）. Compared with the blank group， Real-time PCR results showed that the relative expression level of VIP mRNA in gastric tissues of rats in the model group was significantly decreased（P<0.01）， and the relative mRNA expression levels of AQP3 and AQP4 were significantly increased（P<0.05， P<0.01）. Compared with the blank group， the results of intestinal flora analysis showed that the number of operational taxonomic units（OTUs） and α-diversity increased and β-diversity decreased significantly in the model group， the abundance of Porphyromonadaceae was increased significantly， and the abundance of Oscillibacter_ruminantium was decreased significantly（P<0.05）. Spearman correlation analysis showed that Porphyromonadaceae was significantly positively correlated with AQP4 protein level， while Oscillibacter_ruminantium was significantly positively correlated with VIP protein level， and negatively correlated with AQP3 and AQP4 protein levels（P<0.05）. Linear discriminant analysis effect size（LEfSe） analysis results showed that there were significant differences in a variety of intestinal bacteria between groups， and the intestinal bacteria of the model group were significantly enriched in the phylum/order/family/genus of Elusimicrobia， Betaproteobacteria， Burkholderiales， Sutterellaceae and Parasutterella（P<0.05）. ConclusionSpleen-Yin deficiency syndrome can weaken the digestion and absorption capacity of gastrointestinal tract， and cause the disturbance of water metabolism and intestinal flora. AQP4， AQP3 and VIP protein levels of gastric mucosa are closely related to Porphyromonadaceae and Oscillibacter_ruminantium. And AQP4， AQP3 and VIP may be involved in the regulation of intestinal flora in order to affect the physiological function of spleen governing transportation and transformation.
