Objective:To probe the role of CT in guided thalamotomy and posteroventral pallidotomy for Parknson's disease.Methods:With the help of microelectrode guided technique,ipsilateral thalamotomy and pallidotomy were used for 150 Parkinsonian disease.To fix position with CT in operation,the three dimension for target was measured.Results:80 percent of targets orientated by CT tallyed with that recorded by microelectrode electrophysiology.The error of the rest 20% was less than 2 mm on the average.Conclusions:By CT the targets can be accurately located in 3 dimension during operation.The cost of this kind of orientation is 50 percent less than that of SPCT or MRI.

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 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.

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.

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.

OBJECTIVETo evaluate the effect of supply of fresh poultry products on reducing environment contamination of avian influenza virus (AIV) in markets in Guangzhou.

METHODSA total of 40 markets, including 20 selling alive poultry and 20 selling fresh poultry products, were selected randomly in Guangzhou to conduct environment surveillance in 80 poultry stalls every 4 months from July 2014 to April 2015. Four smear samples were collected from different sites of each poultry stall to detect nucleic acid of AIV. The positive samples were further detected for AIV subtype H5, H7 and H9 nucleic acids.

RESULTSAmong 40 alive poultry stalls, 95.0% (38/40) kept alive poultry overnight, 25.0% (10/40) were disinfected daily, 95.0% (38/40) were cleaned up weekly, 95.0% (38/40) were closed for one day every month. Among 40 fresh poultry product stalls, 20.0% (8/40) were disinfected daily, 90.0% (36/40) were cleaned up weekly, and 96.0% (38/40) ever sold dressed poultry from alive poultry markets. The positive rate of AIV in alive poultry markets was 40.4% (252/623), higher than that in fresh poultry product markets (32.3%, 197/610), the difference was significant (χ(2)=8.85, P=0.003), and the positive rate of subtype H9 virus in alive poultry markets was 28.6% (178/623), higher than that in fresh poultry product markets (16.2%, 99/610), the difference was significant (χ(2)=26.95, P<0.001). In fresh poultry product markets, the positive rate of AIV in stalls selling dressed poultry was 37.3% (180/482), higher than that in stalls selling no dressed poultry (13.3%, 17/128), the difference was significant (χ(2)=26.78, P<0.001), and the positive rate of subtype H9 virus in stalls selling dressed poultry was 19.1% (92/482), higher than that in stalls selling no dressed poultry (5.5%, 7/128), the difference was significant (χ(2)=13.80, P<0.001). Both the positive rate of AIV and the positive rate of subtype H9 virus were highest in the second round surveillance (October 2014). The differences in AIV and its subtype H5, H7 and H9 virus positive rates of environmental samples from four different sites were not significant, respectively. In the same sample site, the positive rate of subtype H9 virus in alive poultry markets was higher than that in fresh poultry product markets the difference was significant (P<0.05).

CONCLUSIONSThe supply of fresh poultry products could effectively reduce the level of environment contamination of AIV in markets. Dressed poultry supplement caused the risk of AIV spread in fresh poultry product markets.
