Objective To investigate cholecystokinin (CCK),carbachol, and vasoactive intestinal peptide(VIP)stimulating peptide chain elongation in mouse pancreatic acini in vitro and its molecular mechanism. Methods ~3H-lecucine incorporation assay was used to measure the basal and secretagogues-stimulated pancreatic acini elongation rates. Western blot was applied to analyse the effect of phosphorylation of the elongation factor 2 (eEF2) and the eEF2 kinase. MEK inhibitor (PD98059), SAPK/p38 inhibitor (SB202190), and mTOR inhibitor (rapamycin) were used to respectively block MEK, SAPK/p38, and mTOR intracellular pathways or the phosphatase inhibitor (calyculin A) pretreatment before CCK treatment. Results All secretagogues except VIP increased the peptide chain elongation in mouse pancreatic acini in vitro. All secretagogues except VIP inhibited the phosphorylation level of eEF2 on Thr-56 and increased the phosphorylation level of eEF2K on Ser-366, which might correlate with their activation status. MEK inhibitor PD98059 partially reversed the dephosphorylation of eEF2 induced by CCK, as did treatment p38 MAPK inhibitor SB202190, mTOR inhibitor rapamycin, and the phosphatase inhibitor calyculin A.Conclusion CCK increases peptide chain elongation via inducement of dephosphorylation of eEF2 and eEF2 kinase phosphorylation in pancreatic acini in vitro. CCK-induced dephosphorylation of eEF2 in pancreatic acinar cells involves MEK, SAPK/p38, and mTOR, the three intracellular pathways.

Objective: To observe the effects of acupoint sticking therapy of different dosages and durations on the subjective and objective sleep indicators in insomnia patients.Methods: Ninety-six patients with insomnia due to liver-Qi stagnation and spleen deficiency were divided into a high-dosage 7 d group (25 cases), a high-dosage 14 d group (22 cases), a low-dosage 7 d group (21 cases), and a low-dosage 14 d group (28 cases) using the random numbers generated in a stratified and stage-by-stage manner in combination with the visiting sequence. The four groups all received the same acupuncture treatment, but acupoint sticking therapy varied in dosage and duration. Before and after treatment, the actigraphic readings (total time in bed, total sleep time, sleep efficiency, number of wake bouts, length of wakes after asleep, and sleep latency), Pittsburgh sleep quality index (PSQI) score, and symptoms score of traditional Chinese medicine (TCM) were observed. A correlation analysis was conducted among the subjective and objective indicators. Results: The PSQI score was positively correlated with the total time in bed and total sleep time (P<0.05). After treatment, the sleep latency, PSQI scores, and TCM symptoms scores changed significantly in the four groups (P<0.05). The total sleep time and sleep efficiency gained improvements after treatment in the high-dosage 14 d and low-dosage 14 d groups (P<0.05). The high-dosage acupoint sticking groups had longer total sleep time compared with the low-dosage groups of the same treatment duration (P<0.05). After treatment, the length of wakes after asleep, PSQI scores, and TCM symptoms scores were better in the 14 d groups than in the 7 d groups of the same acupoint sticking dosage (P<0.05). Conclusion: Given the same acupuncture treatment, acupoint sticking therapy of different treatment durations produces different effects on the length of wakes after asleep, PSQI score, and TCM symptoms score in insomnia patients, and the 14-day acupoint sticking treatment is superior to the 7-day treatment.

Objective To identify biomarkers in cerebrospinal fluid (CSF) by proteomic technology and develop a diagnostic model for neuropsychiatric lupus (NPSLE).Methods CSF proteomic spectra of 27 patients with NPSLE before and after treatment,and 27 controls including 17 patients with scoliosis,and 10 SLE patients without neuropsychiatric manifestation (non-NPSLE) were generated by matrix assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) combined with weak cationic exchange (WCX) magnetic beads.Data were analyzed with t test,non-parametric Kruskal-Wallis H test or Wilcoxon sign-rank test.A decision tree model for NPSLE classification was built based on the discriminating peaks.In addition,CSF samples of 12 patients with NPSLE,12 patients with lumbar disc herniation and 9 patients with other neurological conditions were employed as blind test group to verify the accuracy of the model.Results Twelve discriminating mass-to-charge (m/z) peaks were identified between NPSLE and controls.The diagnostic decision tree model,built with a panel of m/z peaks 8595,7170,7661,7740 and 5806,recognized NPSLE with the sensitivity and specificity of 92.6％ and 92.6％ based on training group samples,91.7％ and 85.7％ based on blind test group,respectively.Conclusion Potential CSF NPSLE biomarkers are identified by proteomic technology,the novel diagnostic model is sensitive and relatively specific for the diagnosis of NPSLE.

Objective To review the diagnosis and treatment of extra-adrenal pheochromocytoma with a 34cases report. Methods Thirty-four cases of extra-adrenal pheochromocytoma were retrospectively analyzed. Hypertension was observed in 27 cases. Abdominal pain was seen in 10 patients and intermittent hematuria in 2 patients. Serum and urinary catecholamine and urinary VMA were measured in 34 cases. The level of serum or urinary catecholamine elevated in 20 cases and urine VMA elevated in 24 cases. Thirty-four cases had ultrasound examination,25 cases underwent CT scan and 6 cases underwent MER scan.Results Pheochromocytomas of 12 cases were located in the renal hilum, 2 in the lower pole of the left kidney, 1 in the posterior aspect of the inferior vena cava, 3 in the interaortocaval region, 2 in the anterior aspect of the abdominal aorta, 1 in the anterior of the right common iliac artery, 1 in the hilum of the liver, 1 in the posterior o{ the pancreas, 2 in the bladder wall, 1 in the posterior of the descending colon, and 8 cases of multifoci. Twenty-two cases of extraadrenal pheochromocytoma were benign and 12 cases were malignant. Thirty cases were followed up from 6 months to 13 years. Among 27 cases with hypertension, the blood pressure of 22 patients returned to normal and 5 cases were still hypertensive. Nine cases of malignant pheochromocytoma all had tumor recurrence or metastases at one year postoperatively. Six patients died during followed-up from 6 months to 3 years, including 3 cases died of cerebral hemorrhage and 3 cases of tumor metastases. Three cases got stable with 131Ⅰ-MIBG radiotheraphy.Conclusions The accurate detecting extra-adrenal pheochromocytoma is difficult. CT scan could be reliable in localizing the lesions. Surgical resection of the tumor could be the best therapy. Patients of malignant extra-adrenal pheochromocytoma may be treated with 131Ⅰ-MIBG after surgical therapy.

OBJECTIVESTo investigate a survey about acceptance of central slaughtering of live poultry in residents of Guangzhou.

METHODSWe conducted a telephone survey by sampling residents with fixed-line telephone and with normal hearing, whose age is more than 15 years, by Mitofsky-Waksberg two-stage method during Jan 6(th) to 8(th), 2014. 358 residents finished the telephone questionnaire by 12 320 health hot line. We investigated the acceptance rate of city-wide central slaughtering permanently. We compared the difference between the respondents and the 2010 Guangzhou census data by Cohen's effect sizes (w) and weighted by population age and sex. We used χ(2) test to compare the acceptance rate of central slaughtering in residents with different characteristic. We used multiple logistic regression analysis to analyze the factors.

RESULTSThe difference in gender and age was small between respondents and the 2010 Guangzhou census data (w value was 0.13, 0.28, respectively), but that in education and marital status was large (w value was 0.52, 0.31, respectively). 49.0% (95% CI: 43.7%-54.3%) accept city-wide central slaughtering permanently. The acceptance rate of city-wide central slaughtering permanently in those who bought fresh, chilled and frozen poultry in their family in previous year was 54.3% (133/245), 60.0% (57/95) and 59.8% (49/82), respectively. It was more than those who didn't buy fresh, chilled and frozen poultry (38.1% (43/113), 44.9% (118/263) and 45.7% (126/276); χ(2) values were 8.15, 6.40 and 5.03; P values were 0.004, 0.011 and 0.025, respectively). The acceptance rate of city-wide central slaughtering permanently in those who deem fresh poultry taste better than live poultry was 64.9% (24/38). It more than those who deem not (47.0%, 151/320) (χ(2) = 4.22, 6.02, P = 0.040, 0.014, respectively). The acceptance rate of city-wide central slaughtering permanently in the male (OR = 2.68, 95% CI: 1.64-4.37) and those who deem getting sick due to buying live birds from LPM (OR = 1.72, 95% CI: 1.05-2.82), who can accept only fresh poultry carcass supply (OR = 2.39, 95% CI: 1.33-4.30), Who bought live poultry in their family in previous year (OR = 0.29, 95% CI: 0.11-0.74), who will decrease the consumption after ban on live poultry sale (OR = 0.50, 95% CI: 0.30-0.83) was 58.6% (109/186), 59.0% (92/156), 60.7% (139/230), 44.9% (132/295), 36.6% (68/186), respectively.

CONCLUSIONIn the early stage of avian influenza A(H7N9) epidemic in Guangzhou, the rate of acceptance of central slaughtering permanently in residents was not so high. Who deem getting sick due to buying live birds from LPM, who could accept only fresh poultry carcass supply and the male more accept city-wide central slaughtering permanently.

Objective:To understand the epidemiological characteristics of imported COVID-19 cases in Guangzhou and provide scientific basis for the prevention and control of the disease.Methods:The data of imported COVID-19 in Guangzhou reported as of April 1, 2020 were collected from National Notifiable Disease Report System of China. The software Excel 2010 and SPSS 19.0 were applied for data cleaning and statistical analysis.Results:As of April 1, 2020, a total of 103 imported COVID-19 cases had been reported in Guangzhou, in which 92 were confirmed cases and 11 were asymptomatic infection cases. The number of the confirmed imported cases accounted for 11.4 % (92/806) in of the total in China at the same time. The male to female ratio of the cases was 1.58∶1 (63∶40). The median age of the cases was 31 years ( P 25- P 75:22-40 years), range of age was 11-63 years. The main occupational distributions of the cases were business services (41/103, 39.8 %) and students (36/103, 35.0 %). The imported cases whose destinations were 19 provinces and municipalities rather than Guangdong after entering the country accounted for 43.7 %. The main source countries of infections were the United Kingdom (27/103, 26.2 %), the Philippines (13/103, 12.6 %), the United States (13/103, 12.6 %) and Nigeria (7/103, 6.8 %). There were 34 inbound flights from which the imported COVID-19 cases were detected, in which 10 flights (10/34, 29.4 %) were found to carry more than 3 cases, with an average voyage time of (11.14±0.53) hours. A total of 29 imported cases(28.2 %) showed symptoms before entering the country, and 65 cases (63.1 %) had been isolated before the onset of the disease. The mean free activity time of the isolated cases after the onset was (6.76±0.79) days. The average number of the imported cases’ close contacts was 53. There were 13 clusters of COVID-19 caused by the imported cases, involving 36 cases (including 1 imported associated case). Conclusions:The sources of the imported COVID-19 cases in Guangzhou were widely distributed, and no cases had been found to be infected on the flights. In the early stage of the imported epidemic, there was high risk for the spread of the epidemic. Strengthened prevention and control of imported COVID-19 effectively reduced the of transmission risk of COVID-19 in communities.

Objective To investigate the expression of long non-coding RNA NONHSA1254644 in lung adenocarcinoma and its clinical significance.Methods 99 cases of lung adenocarcinoma and the adjacent tissues as well as clinical data was collected.The expression level was detected by quantitative realtime polymerase chain reaction (qRT-PCR).Then the relationship between the expression level and the clinical parameters was analyzed.Cell counting kit-8 (CCK8) was used to investigate its effect of lung adenocarcinoma cell line A549 on proliferation.Results The expression of NONHSA1254644 was down-regulated in lung adenocarcinoma,and its expression was positively correlated with the differentiation of patients.The overexpression of NONHSA1254644 could inhibit the proliferation of A549 cells.Conclusions NONHSA1254644 is involved in the development and progression of lung adenocarcinoma.

Objective:To analyze the sensitivity and specificity of SARS-CoV-2 nucleic acid testing in 20 348 close contacts of COVID-19 cases in different prevention and control stages in Guangzhou and to provide scientific evidence for optimizing epidemic response strategies.Methods:A total of 20 348 close contacts of COVID-19 cases in Guangzhou were traced between February 21 and September 22,2020. All the close contacts were tested for the nucleic acid of SARS-CoV-2. The sensitivity and specificity of nucleic acid testing and diagnosis in the different prevention and control stages were compared.Results:In 20 348 close contacts, 12 462 were males (61.24%), the median ( P 25, P 75) of age of them was 31.0 years (23.0,43.0), the median number ( P 25, P 75) of nucleic acid testing for them was 2.0 (1.0,3.0), and the median ( P 25, P 75) of their quarantine days was 12.0 (8.0,13.0) days, respectively. A total of 256 COVID-19 cases were confirmed in the close contacts after seven nucleic acid tests. In the 1 st, 2 nd, 3 rd and 7 th nucleic acid testing, the sensitivity and specificity were 69.14% and 99.99% (177 cases confirmed), 89.84% and 99.99% (230 cases confirmed), 97.27% and 99.99% (249 cases confirmed), and 100.00% and 99.98%, respectively. In the three stages of COVID-19 prevention and control in China: domestic case stage, imported case stage, and imported case associated local epidemic stage, the sensitivity of the 1 st nucleic acid testing was 70.68%, 68.00% and 67.35%, and the specificity was 99.98%, 100.00% and 100.00%, respectively. Conclusions:The sensitivity of nucleic acid testing in the close contacts at the different stages were consistent with slight decrease, which might be related to the increased proportion of asymptomatic infections in the late stage of epidemic prevention and control with COVID-19 in Guangzhou. It is suggested to give three nucleic acid tests to improve the sensitivity and reduce false negative risk.
