OBJECTIVETo verify the regulatory effects of acupuncture on exercise tolerance in patients with chronic obstructive pulmonary disease (COPD) at stable phase.
METHODSThirty cases of COPD were randomly divided into a treatment group (16 cases) and a placebo group (14 cases). Based on specified aerobic exercise, acupuncture was applied in the treatment group and placebo acupuncture was used in the placebo group. The acupoints included Danzhong (CV 17), Rugen (ST 18), Guanyuan (CV 4), Zhongwan (CV 12), Tianshu (ST 25) and so on. The needle did not penetrate into the skin for the placebo group. The treatment was required for 2 to 3 times per week for totally 5 weeks. The indices of exercise tolerance, including 6-min walking distance (6-MWD), exercise time, maximum oxygen uptake (VO2max) forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC), maximum ventilatory volume (MVV), St. George respiratory questionnaire (SGRQ) were observed in two groups before and after treatment.
RESULTS(1) Exercise tolerance: the differences of 6-MWD and exercise time were statistically significant between groups, which were more superior in the treatment group (both P<0.01); the VO2max was significantly increased after treatment in the treatment group (P<0.05), but there was no difference between two groups (P>0.05). (2) Pulmonary ventilation function: the differences of FEV1%, FEV1/FVC and MVV% were statistically significant between groups, which were more superior in the treatment group (P<0.05, P<0.01); (3) SGRQ: the SGRQ was significantly improved after treatment in the treatment group (P<0.05), but there was no difference between two groups (P>0.05).
CONCLUSIONThe acupuncture could improve the exercise tolerance in patients with chronic obstructive pulmonary disease at stable phase, and shorten the onset time of aerobic exercise. Besides, acupuncture combined with aerobic exercise could effectively improve the pulmonary function.

OBJECTIVETo explore the relationship between Chlamydia pneumonia (CP) infection and hypertension as well as the interaction of traditional risk factors and CP infections on hypertension in Chinese Mongolian population.
METHODS1430 inhabitants living in Tongliao city, Inner Mongolia were selected as research subjects, including 488 hypertensives and 942 normotensives. Enzyme-linked immunoassay technique was used to test CP IgG antibody in the blood serum and SPSS 13.0 Microsoft was used to analyze the data.
RESULTSThe prevalence rates of hypertension were significantly different between CP IgG positive and negative groups, However, the trend was attenuated after adjusting age, sex, drinking, smoking, body mass index (BMI) and dyslipidemia. The CP infection rate was significant different in diastolic blood pressure groups, which was significantly higher in 80-84 mm Hg than that in the lowest DBP group. The interaction of chronic CP infection and other traditional risk factors were associated with hypertension in Chinese Mongolian ethnic groups. The ranking with significant sequence from high to low were BMI, dyslipidemia, alcohol intake, sex and age.
CONCLUSIONCP infection was not related to hypertension in Chinese Mongolian ethnic groups but the interaction with other traditional risk factors would increase the risk of developing hypertension.

OBJECTIVETo study the clinical effect and safety of early postnatal application of glucocorticoids in the prevention of bronchopulmonary dysplasia (BPD) in preterm infants.
METHODSThe databases including PubMed, Cochrane Library, Embase, CNKI, Wanfang Data, and VIP were comprehensively searched for articles on early postnatal application of glucocorticoids in the prevention of BPD in preterm infants published up to June 2016. Review Manager 5.3 was used for the Meta analysis of 16 randomized controlled trials (RCTs) that met the inclusion criteria.
RESULTSA total of 2 962 participants were enrolled in the 16 RCTs, with 1 486 patients in the trial group and 1 476 in the control group. The Meta analysis showed that early postnatal application of glucocorticoids reduced the incidence rate of BPD at a corrected gestational age of 36 weeks (OR=0.73, 95%CI: 0.61-0.87, P=0.0004), but there was an increase in the risk of hyperglycemia (OR=1.61, 95%CI: 1.24-2.09, P=0.0003), hypertension (OR=1.63, 95%CI: 1.11-2.38, P=0.01), and intestinal perforation (OR=1.51, 95%CI: 1.12-2.04, P=0.007).
CONCLUSIONSAt present, it is not recommended to use glucocorticoids to prevent BPD in preterm infants. Its advantages and disadvantages need further studies, with special focuses on the adverse effects of hyperglycemia, hypertension, and intestinal perforation.

OBJECTIVETo investigate the association between the polymorphism of potassium voltage-gated channel, Isk-related family, member 1 (KCNE1) gene and atrial fibrillation (AF) in Uigur patients of Xinjiang.
METHODSThree hundred and three patients with atrial fibrillation and 328 healthy controls were tested for the genotype for the KCNE1 gene SNP in the rs1805127 locus by polymerase chain reaction-restriction fragment length polymorphism. The risk factors were also included.
RESULTSThe genotype frequencies of AA, AG and GG were 0.092 (28/303), 0.386 (117/303) and 0.522 (158/303) in the AF patients while they were 0.122(40/328), 0.485 (159/328) and 0.393 (129/328) in controls. There was significant difference in frequencies of the three genotypes (chi-square was 10.465, P=0.005) and G allele (0.715 vs. 0.636, chi-square was 8.907, P=0.003) between the AF and control groups. Logistic regression analysis showed that the KCNE1 polymorphism was the main risk factor of AF in Uigur population. The OR value of genotype GG was 1.55, the 95% CI: 0.73-3.27.
CONCLUSIONFor Uigur population, genetic polymorphism of rs1805127 locus of the KCNE1 gene may increase the risk of atrial fibrillation.

BACKGROUND AND OBJECTIVEEpithelial-mesenchymal transition (EMT) not only initiates invasion and metastasis of tumors, but also induces multidrug resistance in tumor cells. Our experiment analyzed the dependability between breast cancer resistant protein (BCRP) and EMT in breast cancer to explore the effect of EMT on BCRP-mediated multidrug resistance.
METHODSThe expressions of BCRP and transcription inhibitor Snai1 (Snail) in breast cancer were detected by immunohistochemistry. The eukaryotic expression vector pCDNA3.1-Snail was constructed and then transfected into human breast cancer cell line MCF-7. Snail, epithelial marker gene E-cadherin, interstitial marker gene Vimentin, multidrug resistance protein BCRP, and relative drug resistance were measured by immunofluorescence, Western blot, real-time polymerase chain reaction (PCR), and MTT assay.
RESULTSImmunohistochemistry showed that Snail was highly correlated with BCRP in breast cancer. Immunofluorescence, Western blot, real-time PCR revealed that compared with parent cell MCF-7, after transfected with Snail, the expression of E-cadherin in MCF-7 decreased, but Snail, Vimentin, and BCRP increased. MTT displayed that the relative drug resistance increased to 9.93.
CONCLUSIONAfter transfected with eukaryotic expression vector pCDNA3.1-Snail, breast cancer cells MCF-7 showed EMT with BCRP-mediated multidrug resistance.

BACKGROUND: Metabolomics is a branch of systems biology taking systematic study, high-throughput detection and data processing as means, information modeling and systematic integration as targets, which can be used for recognizing metabolic indexes, provide evidence for individualized diagnosis and treatment and guide syndrome differentiation in the clinic. OBJECTIVE: To analyze the literature features and research status of metabolomics applied in the field of Chinese medicine syndromes so as to provide reference for its application in Chinese medicine syndromes. METHODS: Databases of CNKI, WanFang, CBM, PubMed, Web of Science and Medline were retrieved for the articles addressing metabolomics applied in Chinese medicine syndromes published before June 2017. The literature database was established, and then the literature and research features were analyzed using bibliometrics and data mining. RESULTS AND CONCLUSION: Totally 499 articles were enrolled, including 371 journal articles from journals (74.35%), 30 conference papers (6.01), 98 dissertations (19.64), and the 371 journal papers were published in 124 journals (32 of Chinese core journals (45.28%), and 10 SCI cited journals (3.77%)). In the articles, 7 types of disease systems (mainly in digestive system and circulatory system) were classified according to the statistics, involving 23 diseases and 39 interventions. In summary, there is still a lack of standardized classification for metabolomics applied in Chinese medicine syndromes and the quality of literature is poor. We should conduct more animal experiments and explore the essence and intervention measurements of syndromes, thereby controlling the disease occurrence and development.

OBJECTIVETo investigate the effect of early rehabilitation intervention on the incidences of extrauterine growth retardation (EUGR) and early diseases in preterm infants.
METHODSThe appropriate-for-gestational-age preterm infants with a gestational age of <34 weeks and a birth weight of 1 000 to <2 000 g who were admitted to the neonatal intensive care unit (NICU) within 24 hours after birth were enrolled in a prospective randomized controlled trial. These infants were randomly divided into rehabilitation intervention group and control group. The infants in the rehabilitation intervention group were given early rehabilitation after their vital signs became stable, including oral sensory and muscle strength training and pressure touching of the head, chest, abdomen, extremities, hands, and feet. The primary outcome measures were the time to independent oral feeding, length of hospital stay, and incidence rate of EUGR. The secondary outcome measures were the incidence rates of related diseases in preterm infants, such as apnea, feeding intolerance, and sepsis.
RESULTSA total of 97 preterm infants who met the inclusion criteria and had complete data were enrolled, with 48 in the control group and 49 in the rehabilitation intervention group. The rehabilitation intervention group had a shorter time to independent oral feeding than the control group (P<0.05). Compared with the control group, the rehabilitation intervention group had a shorter length of hospital stay and a lower corrected gestational age at discharge (P<0.05), as well as a lower incidence rate of EUGR (P<0.05). The rehabilitation intervention group ONCLUSIONS: Early rehabilitation intervention for preterm infants in the NICU may reduce the incidence rates of apnea, feeding intolerance, and EUGR and help them to achieve independent oral feeding early.

OBJECTIVETo investigate the diagnostic value of contrast-enhanced ultrasonography (CEUS) in preoperative T-staging of gastric cancer.
METHODSA sulfur hexafluoride-filled microbubble ultrasound contrast agent and a continuous real-time imaging technique of contrast pulse sequencing were used. Normal gastric wall was examined by CEUS in 8 healthy volunteers and the results were compared with the findings on multislice computed tomography. Sixty-two patients with gastric cancer proved by biopsies who received preoperative CEUS examination were involved in this study, and the CEUS result was compared with postoperative pathological findings.
RESULTSThe normal gastric wall presented a one-layer structure in the portal venous phase and a three-layer structure in the arterial and equilibrium phase including a slightly hyper-enhanced inner layer, a hypo-enhanced intermediate layer, and a markedly hyper-enhanced outer layer, which corresponded histologically to the mucosal, submucosal, and muscular-serosal layer, respectively. The accuracy of transabdominal ultrasonography and CEUS in determining the T stage of gastric cancer was 72.9% and 88.1% respectively, and the difference was statistically significant (chi(2)=4.37, P=0.036).
CONCLUSIONSCEUS shows the normal gastric wall as a one- or a three-layer structure, which provides a theory base for CEUS in preoperative T-staging of gastric cancer. CEUS is a useful diagnostic method for preoperative T-staging of gastric cancer.

OBJECTIVETo compare the efficacy of nuclear microarray combined with fluorescence in situ hybridization (FISH) and immunohistochemistry in detecting ALK gene translocation and ALK fusion protein in anaplastic large cell lymphoma (ALCL).
METHODSALK gene translocation and ALK fusion protein in 17 paraffin-embedded ALCL specimens were detected using nuclear microarray combined with FISH and immunohistochemical straining, respectively.
RESULTSThe expression of ALK fusion protein was detected immunohistochemically with ALK antibody in 8 of the 17 specimens of systemic ALCL, including 4 with both nuclear and cytoplasmic positivity and 4 with only cytoplasmic positivity. Dual-color FISH identified 6 positive specimens, including the 4 specimens with both nuclear and cytoplasmic positivity as identified immunohistochemically, and 2 with immunohistochemical cytoplasmic positivity. FISH yielded negative results for the 2 specimens with immunohistochemical cytoplasmic positivity.
CONCLUSIONNuclear microarray combined with FISH eliminated the cytoplasmic interference of the results of conventional FISH and provides a high-throughput platform for clinical detection with greater specificity than immunohistochemistry.
