RESUMO
ObjectiveTo explore the distribution and characteristics of traditional Chinese medicine （TCM） syndromes in patients with endometriosis （EMS）. MethodA cross-sectional survey was conducted to analyze the characteristics of TCM syndromes in 1 895 cases of EMS in hospitals of 19 provinces， autonomous regions， and municipalities. ResultAmong the 1 895 patients， Qistagnation and blood stasis syndrome accounted for the highest proportion， followed by Qi deficiency and blood stasis syndrome， cold coagulation and blood stasis syndrome， and kidney deficiency and blood stasis syndrome. The distribution of TCM syndrome types of patients with EMS in different regions， different treatment stages， and different disease types and with different therapeutic goals was different， and the differences were statistically significant. However， under different conditions， the Qi stagnation and blood stasis syndrome accounted for the highest proportion. Under the stratification of different regions， the cold coagulation and blood stasis syndrome in north China was relatively high， the kidney deficiency and blood stasis syndrome in south China was relatively high， and the combined phlegm and stasis syndrome was relatively high in southwest China. Different diagnosis and treatment goals corresponded to different clinical syndromes. With pelvic pain as the main manifestation， the proportion of cold coagulation and blood stasis syndrome was higher. The proportion of kidney deficiency and blood stasis syndrome was higher in married patients with infertility. Patients with the main diagnosis and treatment goals of controlling mass and inhibiting recurrence had a higher proportion of Qi deficiency and blood stasis syndrome. In different treatment stages， the proportion of Qi deficiency and blood stasis syndrome in postoperative patients and those with recurrent EMS was higher. Among different disease types， the Qi deficiency and blood stasis syndrome accounted for a higher proportion in patients with ovarian endometriosis （OEM）. The cold coagulation and blood stasis syndrome accounted for a higher proportion in patients with deep invasive endometriosis （DIE）. The kidney deficiency and blood stasis syndrome accounted for a higher proportion in patients with peritoneal EMS. There were significant differences in age， body mass index （BMI）， and course of disease among patients with different syndromes. Patients with Qi deficiency and blood stasis syndrome was relatively older， and their course of the disease was relatively long. Patients with combined phlegm and stasis syndrome had relatively high BMI. There was no significant difference in CA125 and CA199 levels among all syndrome types. ConclusionThe distribution of TCM syndromes of EMS has a certain regularity， and there are differences in regional distribution， therapeutic goals， treatment stages， and disease types（P<0.05）. However， the Qi stagnation and blood stasis syndrome accounts for a large proportion under different conditions， suggesting that Qi stagnation is the key link of EMS. In the early stage， the team took relieving depression and activating blood as the primary treatment， and created Huoxue Xiaoyi prescription， which was the core prescription for the treatment of EMS with Qi stagnation and blood stasis syndrome， achieving good clinical effect. At the same time， it is emphasized that EMS treatment should be integrated into the concept of chronic disease management and combined with health management. Through psychological counseling， cognitive behavior intervention， popular science lectures， and other methods， it is advised to adjust the emotion of patients with EMS， thereby increasing the curative effect. This study is expected to provide references for the clinical treatment of EMS.
RESUMO
ObjectiveTo explore the effects and possible mechanism of Wenshen Tongdu Formula （温肾通督方， WTF） on spinal cord injury. MethodsThirty-six C57BL/6 female mice were randomly divided into sham operation group， model group and WTF group， with 12 mice in each group. The spinal cord injury model was established in the model group and the WTF group using the modified Allen's method， while in the sham operation group the spinal cord was only exposed. Since the 1st day after surgery， 50 g/（kg·d） of WTF solution was given to the WTF group by gavage， while 20 ml/（kg·d） of normal saline was given to the sham operation and model group by gavage， all for 14 days. Before surgery and on the 1st， 7th， and 14th days after surgery， the motor function of the mice was evaluated using the inclined plane test and hind limb motor function score （by BMS）. On the 3rd day after surgery， the nerve electrophy-siology was detected through electromyography and motor evoked potential； the spleen length was measured， and B cells in the spleen were sorted by magnetic beads； the differential expression of proteins were detected through proteomics technology； and the protein expression of mitochondrial outer membrane transport porin 20 （Tom20） and downstream cleaved caspase-3 in spleen B cells were measured using Western blotting. On the 14th day after surgery， MRI was used to observe the recovery of the spinal cord. ResultsCompared to those in the sham operation group at the same time， the BMS scores and subscores and the inclined plane test angle in the model group were reduced on the 1st， 7th and 14th days after surgery； the peak value of electromyogram and motor evoked potential were reduced， and the spleen length was shortened， while the expression of Tom20 and cleaved caspase-3 increased in splenic B cells increased （P＜0.05）. Compared to those in the model group at the same time， the BMS subscores on the 14th day and the angle of the inclined plane test on the 7th and 14th days after surgery increased in the WTF group； the peak value of electromyography and motor evoked potential， as well as the length of spleen increased， and the expression of Tom20 and cleaved caspase-3 decreased （P＜0.05）. The proteomics results showed that there were 100 differential proteins in the WTF group versus the model group， of which 37 were up-regulated and 63 were down-regulated. GO enrichment analysis showed that differential proteins mainly played their roles in oxygen binding， exogenous apoptosis negative feedback， zinc ion response， and oxygen transport. KEGG enrichment analysis showed that differential proteins were mainly concentrated in metabolic pathways， Huntington's disease， oxidative phosphorylation and other pathways. Subcellular localization showed that differential proteins were associated with mitochondria. Magnetic resonance imaging on the 14th day after surgery showed that the spinal cord structure of the mice in the sham operation group was intact， and the segments were clear， with normal spinal cord signal； the low signal area in the spinal cord injury area increased in the model group， and the spinal cord became significantly thinner； the injured segment had obvious depression in the WTF group， but the structure was more complete than that in the model group. ConclusionWTF may promote spinal cord injury repair by regulating immune function， and its mechanism may be related to inhibiting pyroptosis of spleen B cells.

Conclusions:The levels of serum Cyr61, GLO-1 and miR-155 in patients with endometrial cancer are significantly increased, which are related to clinical stage, degree of invasion, lymph node metastasis and recurrence. Detecting their levels can be used to diagnose endometrial cancer and predict recurrence, so as to guide clinical treatment.
RESUMO
Objective@#To construct the competitive endogenous RNA (ceRNA) network related to gastric cancer and explore the molecular mechanism.@*Methods@#The expression profiles of lncRNA, miRNA and mRNA in gastric cancer and paracancer tissues were analyzed by biochip technology, edgeR package in R software was used to filtrate differential expression genes (multiple change of >1.5 times, P<0.05) and volcano map was drawn. Based on the online miRNA-lncRNA prediction tool lncBase database and the miRNA Target gene prediction database (miRTarBase, target-scan, miRDB, starBase), the relationship between miRNA, lncRNA and mRNA was predicted. Cytoscape software was used to construct lncRNA-miRNA-mRNA ceRNA network and key genes (hub genes) were identified based on cytohubba calculation of degree score of each node. Then Hub genes related to the prognosis of gastric cancer were verified in the TCGA database. The GO and KEGG enrichment analysis of differentially expressed mRNA was performed using the online biological information annotation database DAVID, P<0.05 and false discovery rate (FDR)<0.05 were used as cut-off criteria. R software was used to download the RNA sequencing data and mirna-seq data of gastric cancer and adjacent tissues in TCGA database, edgeR package was used to screen out differentially expressed mRNA, miRNA and lncRNA, and some differentially expressed genes in our data were verified. In OncoLnc database, STAD project of TCGA data was selected and hub gene was input. Patients were divided into two groups based on the median value for hub genes and Kaplan-meier analysis was performed.@*Results@#The differentially expressed 766 mRNA, 110 lncRNA and 10 miRNA were screened out, among them 90 mRNA, 4 lncRNA and 6 miRNA were used to construct the ceRNA network, and 2 of the 20 hub genes were related to the prognosis of patients. MLK7-AS1, SPP1, SULF1, hsa-miR-1307-3p were upregulated in gastric cancer tissues from our biochip, while MT2A, MT1X were downregulated, which were consistent with the results of TCGA gastric cancer database. The differentially expressed mRNAs were significantly enriched in the biological process (BP) and the mineral absorption pathway. CHST1 was negatively correlated while miR-183-5p was positively corelated with the survival of patients.@*Conclusion@#The establishment of ceRNA network for gastric cancer is conducive to further understanding of the molecular biological mechanism. CHST1 and miR-183-5p can be used as prognostic factors of gastric cancer.
RESUMO
The research of acupuncture and moxibustion for endometrial receptivity in recent 10 years was reviewed. CNKI and PubMed databases were retrieved with "acupuncture" "moxibustion" and "endometrial receptivity" as key words. The retrieving time was from January of 2007 through December of 2016. As a result, 63 relevant papers were collected and 28 papers regarding clinical and experimental researches of acupuncture for endometrial receptivity were included into analysis. It was found that acupuncture and moxibustion could improve endometrial morphology (including the expression of pinopodes, endometrial thickness and the rate of endometrial type A), reduce the endometrial microcirculation (including endometrial pulsatility index, resistance index and hemodynamic index), increase the levels of estrogen and progesterone and the expressions of their receptors, and regulate the expression of molecular biological regulator (such as integrin, leukemia inhibitory factor, vascular endothelial growth factor and HOXA10). As a result, the endometrial receptivity was improved to provide good environment for embryo implantation and improve the pregnancy rate, which had significant advantage in the field of assisted reproductive technology. However, detections of pinopodes and integrin were invasive. Its application for clinical use had limitations. In addition, the evidence of acupuncture improving endometrial receptivity was still insufficient. By reviewing related research result, this paper further summarized and analyzed the action mechanism of acupuncture for endometrial receptivity to provide references for the clinical treatment.

Objective@#To analyze the expression and prognostic significance of esophageal squamous cell carcinoma associated long non-coding RNA-1 (ESCCAL-1) in esophageal squamous cell carcinoma (ESCC) tissues. @*Methods@#From August 2011 to May 2013, 73 patients with ESCC, who received radical resection in The First Affiliated Hospital of Zhengzhou University and Henan Cancer Hospital, were enrolled. The expressions of ESCCAL-1 in esophageal tumor tissues and corresponding adjacent non-tumor tissues were detected by quantitative real-time polymerase chain reaction (qRT-PCR). T test, chi square test and multivariate analysis were performed for statistical analysis. @*Results@#The expression of ESCCAL-1 was 28.03±9.37 in esophageal tumor tissues of patients with ESCC, which was higher than that in corresponding adjacent normal tissues (11.39±4.15), and the difference was statistically significant (t=2.964, P<0.01). However there were no statistically significant differences in the expressions of ESCCAL-1 among the patients with different age, gender, histological grade, classification of Union for International Cancer Control (UICC), T stage or lymph nodes metastasis (all P>0.05). The median disease-free survival (DFS) time and overall survival (OS) time of patients with low ESCCAL-1 expression were 39 months and 42 months, respectively, which were longer than those of patients with high ESCCAL-1 expression (30 months and 37 months), and the differences were statistically significant (χ2=9.049, P=0.003; χ2=10.165, P=0.001). The results of multivariate analysis showed that ESCCAL-1 expression was the independent risk factor of DFS and OS (high risk (HR)=2.45, 95% confidence interval (CI) 1.22 to 4.93, P=0.012; HR=2.29, 95%CI 1.14 to 4.59, P=0.019). @*Conclusions@#ESCCAL-1 may be involved the genesis and development of ESCC. The expression of ESCCAL-1 in esophageal tumor tissues may be a prognostic parameter for patients with ESCC receiving radical resection.
RESUMO
Objective@#To explore the expression of long noncoding RNA (lncRNA) HOXA11-AS in esophageal squamous cell carcinoma tissues and the relationship of HOXA11-AS level with clinical outcomes.@*Methods@#Quantitative real-time polymerase chain reaction (qRT-PCR) was applied to detect the expression level of HOXA11-AS in cell lines HET-1A, EC9706, EC109, and in tumor tissue and paired adjacent tissue samples from 73 ESCC patients who received surgical resection.The correlations of the expression level of HOXA11-AS with clinicopathological features and prognosis were also analyzed.@*Results@#The relative expression levels of HOXA11-AS in tumor tissue and paired adjacent tissue were 0.832±0.387 and 2.486±1.087, respectively, with significant difference (P<0.001). The expression of HOXA11-AS was upregulated in 63.0%(46/73)ESCC tissues. The relative expression levels of HOXA11-AS in HET-1A, EC-9706 and EC-109 cells were 1.000, 23.553±3.221 and 17.217±1.968, respectively. The expression level of HOXA11-AS was upregulated in ESCC cell lines (P<0.001). High expression level of HOXA11-AS was correlated with histological grade and lymph node metastasis of ESCC patients (P<0.05). However, it was not associated with the age, gender, depth of infiltration and TNM staging (P>0.05). The median overall survival (OS) and median disease-free survival (DFS) of patients with low HOXA11-AS expression were 43 months and 42 months, respectively, significantly longer than 37 months and 28 months of patients with HOXA11-AS high expression (P<0.05). Cox model multivariate analysis showed that the expression of HOXA11-AS and lymph node metastasis were independent factors of poor prognosis of ESCC patients.@*Conclusions@#The expression of HOXA11-AS is upregulated in esophageal cancer cell lines and tissues. High expression of HOXA11-AS is associated with poor prognosis of ESCC patients.Therefore, LncRNA HOXA11-AS may serve as a predictive marker of postoperative ESCC patients.

RESUMO
Objective To explore whether CCL18 is involved in regulating the expression of miRNAs in breast cancer.Methods The expression profile of miRNAs in the breast cancer cell following CCL18 treatment was determined by miRNAs microarray analysis.Then we performed QRT-PCR and Luciferase Reporter Assay to validate the results from the miRNAs microassay.We used transient transfection to change the expression of miR98 and c-myc in breast cancer cells.We then used QRT-PCR and Western blot to analyze the mechanism by which CCL18 downregulates the expression of miR98 in breast cancer cells.Results miRNAs microarray analysis showed that cells treated with CCL18 differentially expressed 20 miRNAs genes compared with those in the control group. Our QRT-PCR and Luciferase Reporter Assay confirmed the result.The mRNA and protein expressions of C-myc and lin28 were increased after CCL18 stimulation in breast cancer cells.Transfection with c-myc siRNAs rescued the increase of lin28 and loss of miR98 expression caused by CCL18 stimulation.Our results also showed that CCL18 could upregulate the expression of N-Ras at post-transcription level.Conclusion CCL18 downregulates the expression of miR98 via N-Ras/c-myc/lin28 pathway.The downregulated miR98 increases the expression of N-Ras after transfection,which further activates c-myc/lin28 pathway and forms a positive feedback loop.

RESUMO
Objective Based on the immunologic balance, to investigate the mechanisms of Danchi decoction for controlling the recurrence of endometriosis (EMs) of qi stagnation and blood stasis after conservative operation. Methods A multi-center and randomized clinical trial was adopted. EMs patients were divided into Chinese medicine group (CG, 20 cases) and western medicine group (WG, 10 cases). The two groups were given Danchi decoction and GnRH-a or gestrinone respectively for 3 months. The serum IL-2, IL-6 and IL-2/IL-6 were detected before operation, after 3 months of treatment and 3 months after withdrawal, and compared with the control group (5 cases of simple ovarian cysts). Results Before operation, the serum IL-2 level of CG and WG was lower than control group (P0.05), but 3 months after withdrawal, IL-2/IL-6 of WG was significantly lower than that of control group (P<0.05). Conclusion Immune imbalance is closely related to the occurrence and development of EMs. Danchi Decoction or GnRH-a or gestrinone can prevent the recurrence of EMs by adjusting the disorder of immune response, and Danchi Decoction has better effect on long-term result.

RESUMO
We have transferred the different amounts of the plasmid DNA pCGl, which was constructed by cloning rhGM-CSF gene into the eukaryotic expression plasmid pCDS, directly into the BALB/c mice's quadriceps pretreated with bupivacaine. The result of ELISA confirmed that rhGM - CSF was expressed and secreted in mice of group B injected 60?g of plasmid pCGl, but not in mice of group C injected 30?g of plasmid pCGl. The time for the highest level of rhGM-CSF expression was during the fifteenth to twentieth days after plasmid DNA pCGl was injected. Meanwhile, the results of biological activity detection showed that mice's serum of group B (injected 60?g) had the function of retaining the growth of TF - 1 cells. This demonstrates that the rhGM-CSF in mice's serum of group B has certain biological activity. This Model of animal will blaze a new trail in the treatment and prevention of the leukyopenia.
