OBJECTIVE To explore the efficacy of Sour Jujube Seed Decoction combined with Huanglian Wendan Decoction on adult chronic insomnia and its effect on hypnotic withdrawal.METHODS 187 patients with chronic insomnia were included for anal-ysis,including 102 in the traditional Chinese medicine(TCM)group and 85 in the western medicine group.The TCM group was trea-ted with Sour Jujube Seed Decoction combined with Huanglian Wendan Decoction,while the western medicine group was treated with benzodiazepine under the consideration of doctor.The intervention period was 1 month,with assessments using the Pittsburgh Sleep Quality Index(PSQI)conducted before and after the intervention.Follow-up evaluations were performed at 3 months and 6 months re-spectively after the intervention.RESULTS There was no significant difference between the two groups at baseline.After the inter-vention,the PSQI scores of patients in both groups were significantly improved(P<0.01).Among them,the TCM group was better than the western medicine group in the improvement of sleep quality and sleeping pills,total PSQI score reduction(P<0.01).The re-sults of linear regression analysis showed that after controlling for confounding factors,the regression coefficients of the TCM group in two different models were1.821 and 1.922 respectively,and the former was statistically significant(P<0.05).By screening patients who took hypnotics at baseline in the TCM group and comparing them with those in the western medicine group,the influencing factors of hypnotic withdrawal were analyzed.During the 3-month follow-up,25 out of 39 patients in the TCM group and 17 out of 80 patients in the western medicine group had hypnotic withdrawal(χ2= 19.25,P<0.001);during the 6-month follow-up,23 of the 39 patients in the TCM group and 18 of the 79 patients in the western medicine group had hypnotic withdrawal(χ2= 13.53,P<0.001),the with-drawal rate of patients in the TCM group was significantly higher than that in the western medicine group.Further regression analysis showed that after adjusting for confounding factors,the results showed that the western medicine group had a significantly higher rate of not withdrawal than the TCM group at 3 months(OR=5.50,95%CI:2.30～13.72)and 6 months(OR=6.43,95%CI:2.54～17.77),and the results were statistically different(P<0.05).CONCLUSION Sour Jujube Seed Decoction combined with Huangli-an Wendan Decoction is effective in treating adult chronic insomnia and assisting in hypnotic withdrawal.

染色质许可和DNA复制因子1（Cdt1）是复制起始许可的主要调控因子，也是组成复制前复合物的核心成员。细胞通过依赖Cdt1的波动水平，且在每个周期中通过调节其总量以确保DNA仅复制一次。Cdt1功能缺陷会造成DNA过度复制，最终导致基因组不稳定。虽然酵母中cdt1和人类Meier-Gorlin综合征（MGS）患者中的CDT1已被广泛研究，但缺乏脊椎动物模型。我们发现在硬骨鱼类分支的几个鲤形目物种（包括斑马鱼）中，Cdt1蛋白在其N末端插入一段其他脊椎动物中没有的独特无序序列。通过分析在cdt1基因中携带移码缺失的遗传性斑马鱼突变体（命名为cdt1^zju1 ），我们发现突变胚胎虽然几乎无任何早期胚胎表型异常，但成年突变斑马鱼却表现出侏儒症、生存能力降低的症状，以及性腺发育不全且不育。此外，我们同样发现除转录本cdt1-201外，斑马鱼还存在第二个cdt1转录本——cdt1-202，它是通过跳过外显子2产生，这在其他生物中暂无报道。有意思的是cdt1-202在cdt1-201纯合突变体中显著上调。上述研究结果表明，cdt1-202转录本可能可以补偿cdt1-201在早期发育过程中的功能损失，但不能补偿后期生长，这可支持斑马鱼作为研究人类MGS的遗传模型。

Prevotella copri and its related taxa are widely detected in mammalian gut microbiomes and have been linked with an enterotype in humans.However,their microevolution and macroevolution among hosts are poorly characterized.In this study,extensively collected marker genes and genomes were analyzed to trace their evolutionary history,host specificity,and biogeographic distribution.Investigations based on marker genes and genomes suggest that a P.copri-containing lineage(PCL)harbors diverse species in higher primates.Firstly,P.copri in the human gut consisted of multiple groups exhibiting high genomic divergence and conspicuous but non-strict biogeographic patterns.Most African strains with high genomic divergence from other strains were phylogenetically located at the root of the species,indicating the co-evolutionary his-tory of P.copri and Homo sapiens.Secondly,although long-term co-evolution between PCL and higher primates was revealed,sporadic signals of co-speciation and extensive host jumping of PCL members were suggested among higher primates.Metagenomic and phylogenetic analyses indicated that P.copri and other PCL species found in domesticated mammals had been recently transmitted from humans.Thirdly,strong evidence was found on the extensively horizontal transfer of genes(e.g.,genes encoding carbohydrate-active enzymes)among sympatric P.copri groups and PCL species in the same primate host.Our study provides panoramic insights into the combined effects of vertical and horizontal transmission,as well as potential niche adaptation,on the microevolutionary and macroevolutionary history for an enterotype-representative lineage.

Adipose tissue is a promising target for treating obesity and metabolic diseases. However, pharmacological agents usually fail to effectively engage adipocytes due to their extraordinarily large size and insufficient vascularization, especially in obese subjects. We have previously shown that during cold exposure, connexin43 (Cx43) gap junctions are induced and activated to connect neighboring adipocytes to share limited sympathetic neuronal input amongst multiple cells. We reason the same mechanism may be leveraged to improve the efficacy of various pharmacological agents that target adipose tissue. Using an adipose tissue-specific Cx43 overexpression mouse model, we demonstrate effectiveness in connecting adipocytes to augment metabolic efficacy of the β ₃-adrenergic receptor agonist Mirabegron and FGF21. Additionally, combing those molecules with the Cx43 gap junction channel activator danegaptide shows a similar enhanced efficacy. In light of these findings, we propose a model in which connecting adipocytes via Cx43 gap junction channels primes adipose tissue to pharmacological agents designed to engage it. Thus, Cx43 gap junction activators hold great potential for combination with additional agents targeting adipose tissue.

The aim of the present study was to investigate the effect of lipoxin A4 (LXA4)pretreatment on cognitive function of aged rats after global cerebral ischemia reperfusion,and to explore its possible mechanism.Thirty-six aged male Sprague-Dawley rats were randomly divided into three groups (n=12 each):sham-operation group (S group),global cerebral ischemia reperfusion group (I/R group) and LXA4-pretreatment group (L group).The rat model of global cerebral ischemia reperfusion was established by occlusion of the bilateral common carotid artery with hypotension.The cognitive function of rats was determined by a step-down type passive avoidance test and Morris Water Maze test on the third day after reperfusion.Rats were sacrificed after Water Maze test and the pathological changes ofhippocampal CA1 region were observed and the related inflammatory mediators were determined.As compared with S group,the escape latency in I/R group was prolonged from the first day to the fifth day,while that in L group was prolonged from the first day to the third day.The retention time in I/R group and L group in the first quadrant was shortened.The reaction time,frequency of reaction mistake and frequency of escape mistake in I/R group increased,and the latent period shortened.The frequency of escape mistake in L group increased,and the damage in the hippocampal CA1 region of I/R group and L group was obvious.The levels of S-100β,TNF-α,IL-lβ,IL-10 and NF-κB in I/R group and L group increased.As compared with I/R group,the escape latency in L group was shortened from the first day to the fifth day,and the retention time in the first quadrant prolonged.The reaction time,frequency of reaction mistake and frequency of escape mistake in L group decreased,and the latent period prolonged.The damage in the hippocampal CA1 region of L group was alleviated as well.The levels of S-100β,TNF-α,IL-1β and NF-κB in L group decreased,and those of IL-10 increased.It can be concluded that LXA4 pretreatment can improve the cognitive function in aged rats after global cerebral ischemia reperfusion probably by inhibiting the inflammatory reaction.

OBJECTIVETo investigate the predictive value of procalcitonin(PCT) in postoperative intra-abdominal infections (IAI) after definitive operation of intestinal fistulae(IF).

METHODSWith the exclusion of emergence operation, preoperative clinical infection, preoperative renal or hepatic dysfunction, and age less than 18 years, a total of 356 consecutive patients who underwent elective digestive tract reconstruction of intestinal fistulae from February 2012 to December 2015 at Intestinal Fistula Center of Jinling Hospital were prospectively enrolled in the study. All the patients were divided into IAI group (26 cases, 21 of anastomosis leakage and 5 of peritoneal abscess) and non-IAI group (330 cases) based on the existence of postoperative IAI. The non-IAI group was then divided into two subgroups of other infection (93 cases) and non-infection(237 cases) according to the presence of other infections. Plasma PCT level, serum CRP concentration and WBC count were assessed preoperatively and on postoperative days (PODs) 1, 3, 5, 7 by immunofluorescence, turbidimetry and automatic blood analyzer, respectively. The predictive value of each marker for IAI was calculated by receiver operating characteristic (ROC) curve.

RESULTSThere was no significant difference in general clinical data between IAI and non-IAI group (all P>0.05). The proportions of multi-IF (53.8%, 14/26) and colectomy (61.5%, 16/26) in IAI group were higher than those of non-IAI group [20.0% (66/330), χ=15.847, P=0.000 and 31.2%(103/330), χ=9.961, P=0.002]. Differences of preoperative PCT, CRP and WBC levels among IAI, other infection and non-infection groups were not significant. These three markers all increased obviously and immediately after surgery. PCT and WBC values reached the peak point on POD 1, whereas CRP on POD 3. In IAI group, mean PCT values were (5.4±4.2) μg/L, (2.9±1.9) μg/L and (1.6±1.8) μg/L on POD 1, POD 3 and POD 5, respectively, which were higher than those of other infection group [(4.2±8.7) μg/L, (1.9±3.8) μg/L and (0.6±0.8) μg/L] and non-infection group [(2.7±5.8) μg/L, (1.1±1.7) μg/L and (0.5±0.7) μg/L, all P<0.05]. Mean CRP values in IAI group were 99.4 mg/L and 183.9 mg/L respectively on POD 1 and POD 3,and mean WBC values of IAI group on POD 1, POD 3 and POD 5 were 16.0×10/L, 10.8×10/L and 8.7×10/L, respectively, which were all significantly higher than those in the other 2 groups (all P<0.05). No significant differences were obtained between other infection group and non-infection group in all these three markers (all P>0.05). ROC curve demonstrated that PCT had the biggest area under the curve (AUC) of 0.86 and 0.84 on POD 3 and POD 5, with the cut-off value of 0.98 μg/L and 0.83 μg/L, 92.0% sensitivity and 74.0% specificity, 91.0% sensitivity and 73.0% specificity, respectively. The highest AUC was 0.72 on POD 3 for CRP and 0.71 on POD 3 for WBC, with 80.0% sensitivity and 54.0% specificity, 56.0% sensitivity and 73.0% specificity, respectively.

CONCLUSIONThe value of procalcitonin above 0.98 μg/L on POD 3 and 0.83 μg/L on POD 5 can predict the occurrence of IAI after definitive operations of intestinal fistulae.

Crohn disease (CD) is a chronic inflammatory disease which progressively affects the digestive tract with unknown etiology. During the disease course, intestinal fibrosis will gradually develop in many CD patients and results in irreversible fibrosis stricture, causing refractory abdominal pain and even intestinal obstruction, and necessitating one or more surgical interventions. Thus far the exact etiology of CD remains unknown. It is believed that genetic, environmental and immunologic factors are involved, which may also predict the development of intestinal fibrosis. Recent studies have found the association of mutations in genes, such as NOD2, ATG16L1, CX3CR1, IL-23R and MMP3 with the fibrogenic phenotype of CD. In addition, serum extracellular matrix molecules, growth factors, miRNAs and microbial antibodies have also been linked to the fibrogenesis in CD patients, however the results of researches were divergent. Therefore it is of significance to explore noninvasive markers of intestinal fibrosis with high sensitivity and specificity, and the high-throughput proteomic technique may be an approach that deserves further investigation. Screening the high-risk patients for the fibrostenotic phenotype of CD by susceptibility genes, and early detection of intestinal fibrosis using noninvasive serum markers, will help improve the treatment outcomes and reduce the surgical rates. The article aims at summarizing the current susceptibility genes and serum markers of intestinal fibrosis in CD.

Background: Liver regeneration is dependent on the proliferation of hepatocytes. Hepatic progenitorcells are intra-hepatic precursor cells capable of differentiating into hepatocytes or biliary cells.Although liver progenitor cell proliferation during the regenerative process has been observed in animalmodels of severe liver injury, it has never been observed in vivo in humans because it is unethicalto take multiple biopsy specimens for the purpose of studying the proliferation of liver progenitorcells and the roles they play in liver regeneration. Associating liver partition and portal vein ligationfor staged hepatectomy (ALPPS) is a staged procedure for inducing remnant liver hypertrophy sothat major hepatectomy can be performed safely. This staged procedure allows for liver biopsyspecimens to be taken before and after the liver begins to regenerate. Case presentation: The liverprogenitor cell proliferation is observed in a patient undergoing ALPPS for a metastatic hepatictumour. Liver biopsy is acquired before and after ALPPS for the calculation of average number ofliver progenitor cell under high magnification examination by stain of immunomarkers. This is thefirst in vivo evidence of growing liver progenitor cells demonstrated in a regenerating human liver.

BACKGROUND/AIMS: Neurotensin is a gut-brain peptide with both inhibitory and excitatory actions on the colonic musculature; our objective was to understand the implications of this for motor patterns occurring in the intact colon of the rat. METHODS: The effects of neurotensin with concentrations ranging from 0.1-100 nM were studied in the intact rat colon in vitro, by investigating spatio-temporal maps created from video recordings of colonic motility before and after neurotensin. RESULTS: Low concentration of neurotensin (0.1-1 nM) inhibited propagating long distance contractions and rhythmic propagating motor complexes; in its place a slow propagating rhythmic segmental motor pattern developed. The neurotensin receptor 1 antagonist SR-48692 prevented the development of the segmental motor pattern. Higher concentrations of neurotensin (10 nM and 100 nM) were capable of restoring long distance contraction activity and inhibiting the segmental activity. The slow propagating segmental contraction showed a rhythmic contraction—relaxation cycle at the slow wave frequency originating from the interstitial cells of Cajal associated with the myenteric plexus pacemaker. High concentrations given without prior additions of low concentrations did not evoke the segmental motor pattern. These actions occurred when neurotensin was given in the bath solution or intraluminally. The segmental motor pattern evoked by neurotensin was inhibited by the neural conduction blocker lidocaine. CONCLUSIONS: Neurotensin (0.1-1 nM) inhibits the dominant propulsive motor patterns of the colon and a distinct motor pattern of rhythmic slow propagating segmental contractions develops. This motor pattern has the hallmarks of haustral boundary contractions.
