Objective To research a more economical and convenient test way, which uses excimer laser therapeutic apparatus eye-test of Allegretto Wave Eye-Q. Methods In testing, a film of transparent and fit thickness was coved on original test-chip to exam. Results Test paper can be reused and determines clearly of all cases. Conclusion The modified method not only raises efficiency and reduces cost, but also saves test specimen with easy operation.

Objective To evaluate the feasibility of suprasternal mini-thyroidectomy.Methods A total of 15 patients with nodular goiter underwent suprasternal mini-thyroidectomy(2.5-3.5 cm in incision at length) with ultrasonic scalpel.Results All operations including unilateral partial thyroidectomy(n=4),unilateral subtotal thyroidectomy(n=2) and bilateral subtotal thyroidectomy(n=9)were completed successfully.The mean operation time was 46 minutes(range,30-65 minutes).The intraoperative blood loss was less than 10 ml,except 25 ml in one patient.No complications occurred except superficial Ⅱ degree skin burn in 2 patients.The mean postoperative hospital stay was 1.8 days(range,1-3 days).All the patients were followed up for 8-10 months and no recurrence was found.Conclusions Suprasternal mini-thyroidectomy is feasible and safe with certain cosmetic effects.

Objective:To investigate the changes and the adjusting effects of brain-gut peptides (BGP) on immunologic function in the rats before and after relief of biliary obstruction.Methods:One hundred Wistar rats were randomly divided into five groups,including sham common bile duct ligation group (group A),common bile duct ligation group (group B),sham relief of biliary obstruction + normal saline group (group C) ,relief of biliary obstruction + normal saline group (group D) and relief of biliary obstruction + Sandostatin (group E).At 1d,7d after the operation of each group,the changes of plasma vasoactive intestional peptide (VIP),substance P(SP),serum interleukin-2(IL-2) and serum T-lymphocytic subsets (CD4 +,CD8 +)were determinded by radioimmunoassay and flowcytometry .Results:Plasma VIP and SP were increased in group B compared with group A(P

To enhance speech recognition, as well as Mandarin tone recognition in noice, we proposed a speech coding strategy called zero-crossing of fine structure in low frequency (LFFS) for cochlear implant based on low frequency non-uniform sampling (LFFS for short). In the range of frequency perceived boundary of human ear, we used zero-crossing time of the fine structure to generate the stimulus pulse sequences based on the frequency selection rule. Acoustic simulation results showed that although on quiet background the performance of LFFS was similar to continuous interleaved sampling (CIS), on the noise background the performance of LFFS in Chinese tones, words and sentences were significantly better than CIS. In addition to this, we also got better Mandarin recognition factors distribution by using the improved index distribution model. LFFS contains more tonal information which was able to effectively improve Mandarin recognition of the cochlear implant.

OBJECTIVETo explore the clinical application value of Provider-Initiated HIV Testing and Counseling (PITC) by analyzing the positive rate of HIV tests for people in need of PITC and that of routine HIV tests.

METHODSWe retrospectively analyzed the demographic and epidemiologic data about the patients seeking PITC services or undergoing routine HIV tests in Nanjing Drum Tower Hospital between January and December 2013.

RESULTSThe positive rate of initial HIV screening was 1.98% in the PITC group and 0.24% in the routine test group, while that of confirmed HIV was 0. 40% in the former and 0.07% in the latter, both with statistically significant differences between the two groups (P < 0.01). The positive rate of HIV was markedly higher in males than in females, particularly in the PITC group.

CONCLUSIONPITC has a high clinical value in HIV detection for targeted subjects and therefore deserves general application in dermatology.

Objective To detect the ascites CD64 index of patients with decompensated cirrhosis ,and explore the value in the di-agnosis of spontaneous bacterial peritonitis (SBP) .Methods Decompensated cirrhosis with ascites patients were divided into non-SBP group ,SBP suspected group and SBP diagnosed group .Two control groups were composed of patients with ascites culture pos-itive and non-SPB group .SBP suspected group were further grouped according to abdominal pain and the percentage of peripheral blood neutrophils .The CD64 index was detected by flow cytometry .Compared the difference of ascites CD64 index after treatment , and analyzed diagnosis performance of procalcitonin in human peripheral blood and ascites white blood cell count of SBP .Results The level of the ascites CD64 index was significantly higher in SBP diagnosed group (179 .39 ± 65 .56)and SBP suspected group (115 .49 ± 58 .42)than that of non-SBP group(26 .88 ± 26 .05)(P<0 .01) .The differences of the ascites CD64 index between SBP suspected associated with abdominal pain group and SBP suspected associated with painless group was not statistically significant (P>0 .05) .The level of the ascites CD64 index in SBP suspected with percentage of peripheral blood neutrophils elevated group was increased significantly than non-elevated group(P<0 .05) .CD64 index level in effective treatment group was significantly lower than the ineffective treatment group(P<0 .01) .The area of the ascites CD64 index under the curve was greater than procalcitonin in human peripheral blood and ascites WBC count ,and had a higher sensitivity and specificity .Conclusion The detection process of the ascites CD64 index is fast and with less influential factors ,which provides a new choice for the clinical diagnosis of SBP .

Objective To identify the different causes of atrial fibrillation (AF) in Chinese by coronary artery angiography,and to compare the episode of stroke in different patients.Method A total of 782 adult patients diagnosed with AF were identified from Anzhen Hospital over a 8-year period.There were 273 patients with rheumatic valvular AF and 509 patients with nonvalvular AF.The results of electrocardiogram,echocardiography and coronary artery angiography were retrospectiwely analyzed to find out the proportion of causes and to compare the episode of stroke in patients with rheumatic valvular AF with those having nonvalvular AF.Results The patients with rheumatic valvular atrial were significantly younger than of coronary heart disease (52.40?5.03 years old vs 64.30?3.25 years old,P

The deep fermentation technique of Tricholoma matsutake is systemically studied in this paper firstly. The best culture determined by orthogonal test is 3g/L of cornflour, 1g/L of glucose, 1g/L of bean cake flour, 1mL/L of corn steep liquid, 1g/L of KH 2PO 4. The best fermenting condition is: 25℃, rotating speed 160 r/min, pH5.0,inoculating amount 10%, 120mL culture medium per 500mL flask. Under these conditions, the mycelia reach 12.94g/L after fermenting 12d.
