OBJECTIVETo observe the clinical effect of the combined use of amiodarone and Wenxin Granule (WXG) in auricular fibrillation (AF) conversion and its safety.

METHODSTwo hundred and twenty-four patients, in whom AF lasted for less than 1 year, were enrolled and randomly assigned into two groups, 112 in each group. Patients in the treated group were treated with WXG and amiodorane and the others in the control group were orally administered with amiodarone alone. The accumulative conversion rate of AF and adverse reaction were monitored during the 6-month observation period.

RESULTSSix-month observation was completed in 109 cases in the treated group and 107 in the control group, while 3 cases and 5 cases in the two groups were dropped out respectively. The difference of accumulative AF conversion rates between the two groups become significant early after one month medication (P < 0.05), and was 65.1% and 47.7% respectively after 6-month of treatment (P < 0.05). Inter-group significant difference was also shown in the aspects of average conversion time, dosage of amiodarone required and the occurrence of adverse reaction (P < 0.05).

CONCLUSIONCombined use of WXG and amiodarone has a better effect in improving conversion rate of AF, shortening conversion time and decreasing the required dosage of amiodarone in treating AF as compared with the treatment with amiodarone alone, and by which the adverse reaction of long-term using amiodarone could be avoided.

OBJECTIVETo explore the correlations of circulating tumor cells (CTCs) and disseminated tumor cells (DTCs) with the clinicopathological characteristics, prognostic events, and survival outcomes in esophageal cancer (EC) patients.

METHODSThe PubMed, Web of Science, Embase database and Cochrane database were searched for studies reporting the outcomes of interest. The studies were selected according to established inclusion/exclusion criteria. Meta-analysis of the studies was performed using Review Manager 5.3 and Stata12.0 software with the odds ratio (OR), risk ratio (RR) , hazard ratio (HR) , and 95% confidence interval (95% CI) as the effect indexes.

RESULTSNineteen studies involving a total of 1766 patients were included in the analysis. Significant correlations of CTCs and DTCs were found with the clinicopathological parameters including the tumor stage (OR=1.95), depth of invasion (OR=1.99), lymph node metastasis (OR=2.44), distal metastasis (OR=5.98), histological differentiation (OR=1.67) and lymphovascular invasion (OR=4.48). CTCs and DTCs were also correlated with the prognostic events including relapse (RR=6.86) and metastasis (RR=3.22) and with the survival outcomes including the overall survival (OS) overall analysis (HR=3.46) and disease-free survival/progression-free survival (DFS/PFS) overall analysis (HR=3.00).

CONCLUSIONCTCs and DTCs are significantly associated with an advanced tumor stage, depth of tumor invasion, lymph node metastasis, distant metastasis before therapy, differentiation, lymphovascular invasion, relapse and metastasis in patients with EC. They are also significantly correlated with a poorer survival for OS and DFS/PFS to serve as clinical and prognostic predictors in patients with EC.

OBJECTIVETo understand the immunological status of Japanese encephalitis (JE) antibodies amongst migrant workers and to provide epidemiological basis for public health strategies on JE prevention and control in Shenzhen.

METHODSA multi-stage random sampling method was used, and 1003 migrant workers aged 18 to 60 from 44 factories were investigated and their serum specimens were collected. The enzyme-linked immunosorbent assay (ELISA) was used to detect JE antibodies qualitatively.

RESULTSThe gross IgG seroprevalence rate for JE was 20.2% (203/1003). Sex-specified seroprevalence was 21.2% (103/485) for male and 19.3% (100/518) for female, respectively (χ(2) = 579, P > 0.05). Age-specific seropositive rates were 22.6% (12/53) for those below 20 years old, 18.7% (120/642) for those between 20-years old, 26.0% (58/223) for those between 30-years old and 15.3% (13/85) for those on or above 40 years old (χ(2) = 7.96, P > 0.05). Proportions for self-reported positive immunization, non-immunization and unclear immunization history were 22.1% (30/136), 22.1% (51/231) and 19.2% (122/636), respectively (χ(2) = 501, P > 0.05). Seroprevalence by region of origins showed that workers from Guangdong province was the highest (30.5%, 50/164), followed by workers from Guangxi (29.7%, 22/74) whilst workers from Shan(3)xi (5.4%, 2/37) had the lowest rate. Seroprevalence rate for managers (29.0%, 31/107) was higher than that of technicians (7.1%, 1/14) (χ(2) = 21.78, P < 0.05). Serological positive rate of workers with university or above educational background was the highest (32.7%, 16/49), followed by that for individuals with college degree (10.3%, 10/97) (χ(2) = 13.02, P < 0.05).

CONCLUSIONNo associations are detected between JE seroprevalence and age, or sex, or self-reported immunization histories amongst migrant labor workers in Shenzhen. However, correlations between JE serological positive rate and region of origins, occupation and educational attainment are found to be significant. The gross seroprevalence of JE antibodies suggests that the level of JE antibodies amongst Shenzhen migrant workers is low and the population immunity barrier has yet to be established. It is necessary to strengthen prevention and control strategies of JE among labor workers of Shenzhen.

OBJECTIVETo investigate the expression of Yin Yang 1 (YY1) protein in human insulinoma and explore its clinical significance.

METHODSNineteen pancreatic neuroendocrine tumor tissue were collected from patients treated in Nanfang Hospital between 2000 and 2014. The protein expression of YY1 in benign and malignant insulinoma tissues were detected by immunohistochemistry.

RESULTSPositive expression for YY1 protein was detected in both benign and malignant tumor tissues, but the malignant tissues had a significantly greater intensity of YY1 expression than the benign tissues (P=0.042). The intensity of YY1 expression was positively correlated with the nature of the tumor, and the insulinomas with high expressions of YY1 had significantly greater malignant potentials (P=0.037).

CONCLUSIONThe high expression of YY1 protein is associated with the development of insulinima. YY1 may serve as a new tumor marker for detecting the malignant transformation of insulinoma.

OBJECTIVETo investigate the effect of VEGF (vascular endothelial growth factor) gene therapy and skin flap delay on the survival of rat's abdominal axial skin flap.

METHODSIn 48 Wistar rats, the model of a abdominal axial skin flap supplied by right superficial epigastric vessel was created. The rats were divided into six groups. The group was treated with subcutaneous injection of pcDNA4-VEGF165, skin flap delay or VEGF injection combined with skin flap delay. 7 days later, the survival rate of the skin flap was measured; specimens were harvested from the skin flap for histological investigation of the microvessels and for immunohistochemical staining to observe the expression of VEGF.

RESULTSEvery treated group was significantly higher than blank group in the average survival rate of the skin flap and group V (gene injection when delayed) has the highest one. The average number of the microvessels in group II, III, V, VI was significantly higher than group IV and blank group. Group IV > group V, VI > group II, III > blank group in lumen diameter of the microvessels. Immunohistochemical staining documented more deposition of VEGF DNA in group II, III, V, VI than group IV and blank group.

CONCLUSIONSBoth administration of pcDNA4-VEGF165 and skin flap delay can improve the survival of rat's abdominal axial skin flap, but the mechanisms of the effect were different. The combination of the two ways has stronger effect.

OBJECTIVETo study how to perform the hearing screening on the infants in the rural area.

METHODSThree thousand nine hundreds and twenty-two infants, about 84% of them from rural, were born in the People Hospital of LaiZhou City from January to December in 2004. The infants were performed fast hearing screening by transient evoked otoacoustic emission (TEOAE) after the birth in 2-7 days. The fail cases were checked again after 4-6 weeks, and then were diagnosed if they still failed after following-up.

RESULTSThe infants (3612/3922, 92.1%) have been checked by TEOAE, and the examination was free in the poverty cases. The rate passed on the first check was 69.96% (2527/3922), but 1085 infants failed (30.4%), while 310 infants have not been checked (7.9%). In the 1085 cases that should be rechecked, there was only 633 cases (58.34%) accepted the check on time, while 452 cases (41.66%) missed. In the 163 cases with high-risk infants in 2004, 114 infants (69.96%) were checked, but 49 infants (29.04%) were not checked. Fourteen cases failed in the recheck, and 11 of them were checked by ABR. Two cases were found to be moderate and severe hearing loss in binaural respectively and 4 cases with mild hearing loss in monaural while 3 cases were normal.

CONCLUSIONSIt is necessary and viable for the infants on hearing screening in the rural area It should be set up and perfected the model for infants on hearing screening in rural area as soon as possible; it should be free for the poor infants to make sure everyone enjoy the health care.

Background/Aims: Esophagogastric junction adenocarci-noma (EJA) is a malignant tumor associated with high mor-bidity and has attracted increasing attention due to a rising incidence and low survival rate. Pathological biopsy is the gold standard for diagnosis, but noninvasive and effective tests are lacking, resulting in diagnoses at advanced stages.This study explored the diagnostic value of insulin-like growth factor binding protein 7 (IGFBP7) in EJA. Methods: A total of 120 EJA patients and 88 normal controls were recruited, and their serum levels of IGFBP7 were measured by enzymelinked immunosorbent assay. Receiver operating character-istic (ROC) curve analysis was used to assess the diagnostic value, and Pearson chi-square analysis was used to evaluate the correlation between IGFBP7 and clinical parameters. Ka-plan-Meier survival analysis was carried out to assess the ef-fect of IGFBP7 on overall survival (OS). Results: The levels of IGFBP7 were higher in both early- and late-stage EJA patients than in normal controls (p<0.001). The area under the ROC curve for EJA patients was 0.794 (95% confidence interval [CI], 0.733 to 0.854), with a cutoff value of 2.716 ng/mL, a sensitivity of 63.3% (95% CI, 54.0% to 71.8%) and a specific-ity of 90.9% (95% CI, 82.4% to 95.7%). For the diagnosis of early-stage EJA, the same cutoff value and specificity were obtained, but the sensitivity of IGFBP7 was 54.3% (95% CI, 36.9% to 70.8%). Patients with low IGFBP7 protein expres-sion had lower OS than those with high expression (p=0.034).The multivariate analysis showed that IGFBP7 is an inde-pendent prognostic factor for EJA (p=0.011). Conclusions Serum IGFBP7 acts as a potential diagnostic and prognostic marker for EJA.

OBJECTIVE: To observe the clinical efficacy of acupuncture method for mild cognitive impairment in the elderly. METHODS: A total of 96 patients were randomly divided into an observation group, a control group and a waiting group, 32 cases in each group. The patients in the observation group were treated with acupuncture at Baihui (GV 20), Shenting (GV 24), Yintang (GV 29) and Sishencong (EX-HN 1), etc, while the patients in the control group were treated with nonpenetrating sham acupuncture at the same acupoints as the observation group. The treatment was given once every other day, three times a week for 8 weeks. The patients in the waiting group only received health guidance for 8 weeks. Montreal cognitive assessment scale (MoCA) and mini-mental state examination (MMSE) were used before and after 8-week treatment in all three groups. The observation group and the control group were followed up for 2 months and evaluated with MoCA and MMSE. RESULTS: The MoCA scores in the observation group after treatment and during follow-up were higher than before treatment (<0.01), but there was no significant difference between follow-up and after treatment (>0.05). The MoCA scores in the control group after treatment and during follow-up were higher than before treatment (<0.01, <0.05), and the MoCA score during follow-up was lower than after treatment (<0.01). There was no significant difference before and after treatment in the waiting group (>0.05). The difference before and after treatment in the observation group was higher than the control group and waiting group (<0.01), while that in the control group was higher than the waiting group (<0.01). The difference between follow-up and before treatment in the observation group was higher than the control group (<0.01), and the improving between follow-up and after treatment was superior to the control group (<0.01). The MMSE scores after treatment and during follow-up were higher than before treatment in the observation group (<0.01), but there was no significant difference between the follow-up and after treatment (>0.05). The MMSE scores after treatment and during follow-up were higher than before treatment in the control group (<0.01), and the MMSE score during follow-up was lower than after treatment (<0.01). There was no significant difference before and after treatment in the waiting group (>0.05). The difference before and after treatment the observation group and control group was not significant (>0.05), and those in the two groups were higher than the waiting group (<0.01). The difference between follow-up and before treatment in the observation group was higher than the control group (<0.01), and the difference between follow-up and after treatment was lower than the control group (<0.01). CONCLUSION acupuncture method could improve cognitive impairment in elderly patients with mild cognitive impairment.
