Objective To investigate changes in serum levels of Th22 cell ? related cytokines and complements in patients with drug eruption before and after treatment, and to explore their possible roles in the occurrence and development of drug eruption. Methods This study included 35 patients with drug eruption, and 35 sex?and age?matched healthy controls. Five milliliters of peripheral blood samples were collected from the controls and patients before and after treatment. Enzyme?linked immunosorbent assay(ELISA)was performed to measure serum levels of interleukin 22(IL?22)and IL?13, and the cytometric bead array(CBA)system was used to determine serum levels of tumor necrosis factor?α(TNF?α) and complement components C3a, C4a and C5a. Results Before treatment, the patients with drug eruption showed significantly higher serum levels of IL?22(40.85 ± 14.56 vs. 29.09 ± 8.66 ng/L, t=5.549, P<0.05), IL?13(869.94 ± 463.39 vs. 372.92 ± 151.75 ng/L, t=6.071, P<0.05), TNF?α(1.03 ± 0.64 vs. 0.44 ± 0.31 ng/L, t=4.321, P<0.05), complement C3a(55.21 ± 32.98 vs. 42.44 ± 14.26 ng/L, t=2.832, P<0.05), C4a(285.11 ± 123.91 vs. 237.00 ± 63.57 ng/L, t=2.257, P<0.05), and C5a(279.68 ± 127.72 vs. 215.98 ± 65.38 ng/L, t=2.495, P<0.05)compared with the controls. After treatment, the serum levels of IL?22, IL?13, TNF?α, complement C3a, C4a and C5a in patients decreased to(32.72 ± 11.77)ng/L,(456.21 ± 123.22)ng/L,(0.64 ± 0.39)ng/L,(45.47 ± 21.11)ng/L,(241.86 ± 84.12)ng/L and(239.61 ± 103.51)ng/L respectively, with a significant difference between the pretreatment and posttreatment values of these proteins(t = 4.443, 5.197, 3.572, 3.213, 2.728 and 4.772, respectively, all P ≤ 0.01). Additionally, the serum levels of IL?22 and IL?13 were still significantly higher in the patients than in the controls(both P < 0.05), while there were no significant differences in the serum levels of TNF?α, complement C3a, C4a or C5a between the patients and controls after treatment(all P > 0.05). Correlation analysis showed positive correlations between complement C3a and C4a serum levels(r = 0.660, P < 0.05), between C3a and C5a serum levels(r = 0.404, P < 0.05), between C4a and C5a serum levels(r = 0.501, P < 0.05), and between IL ? 22 and TNF ? α serum levels(r = 0.573, P = 0.005), but negative correlations between IL ? 22 and complement C3a serum levels(r = -0.490, P = 0.005), in patients before treatment. Conclusion The activation of Th22 cell?related cytokines and complements may play important roles in the occurrence and development of drug eruption, and IL?22 may participate in the regulation of complements.

Objective To investigate the clinical features of fungal sepsis in premature infants.Methods The risk factors,clinical characteristics,laboratory findings,treatment and prognosis of 30 preterm infants with fungal sepsis in neonatal intensive care unit of the First Mfiliated Hospital of Anhui Medical University from Jan.2010 to Dec.2012 were analyzed.Results Fourteen cases (46.7％) were extremely preterm infants.The gestational ages of 20 cases(66.7％) were less than 34 weeks.The preterm infants were infected with fungal sepsis at the age of 6-42 d,and the mean age was (15.70 ± 9.02) d.The most common pathogens were Candida albicans (83.3％) and Candida glabrata(13.3％).Before infection,6 cases accepted the endotracheal intubation and mechanical ventilation,9 cases accepted Peripherally Inserted Central Catheter with the duration more than or equal to 7 days,and 5 cases accepted multi-antibiotic treatment with the duration more than or equal to 14 days,with the main clinical manifestations including poor response in 25 cases (83.3％),poor feeding in 25 cases (83.3％),and blood oxygen concentration decrease in 20 cases (66.7％).There were 27 cases(90.0％) with the increased C-reactive protein(CRP),5 preterm infants with the white blood cell count less than 5.0 × 109/L,5 patients with the white blood cell count more than 15.0 × 109/L,and 20 cases (66.7 ％) with thrombocytopenia.Among those 30 cases,2 cases (6.7 ％) abandoned therapy,4 cases (13.3％) accepted liposomal amphotericin B because of the poor efficacy to fluconazole,and 24 cases (80.0％) accepted fluconazole.Of the 28 cases,4 cases(13.3％) were improved,24 cases(80.0％) were cured and no one died.Conclusions The proportion of Candida albicans species increased during the cause of fungal sepsis in premature infants.It was probably the cause of fungal sepsis when preterm infants had poor response,poor feeding,blood oxygen concentration decrease in 2-3 weeks after birth.Possible strategies were recommended including strict aseptic manipulation,rational use of antibiotics,antifungal prophylaxis for preterm infants who have risk factors in highoccurrence season in order to decrease the morbidity and mortality of neonatal fungal sepsis.

OBJECTIVETo study the changes of lower esophageal sphincter (LES) high-pressure zone, and to determine the accurate length of myotomy on the esophageal and gastric sides.

METHODSThere were 15 patients undergoing the Heller's cardia-myotomies and Toupet fundoplications from May 2006 to December 2007. Among them, 9 patients were female and 6 was male. The age ranged from 28 to 61 years old, and the disease duration ranged from 6 months to 9 years. The intraoperative oesophageal manometry underwent in the surgical procedures to investigate the changes of the lower esophageal sphincter pressure and the length of myotomy.

RESULTSThere was no postoperative death. After (5.3 +/- 1.5) cm of esophageal side myotomy and (0.8 +/- 0.4) cm of gastric side myotomy, the mean LES pressure decreased from (33.6 +/- 13.3) mm Hg (1 mm Hg = 0.133 kPa) to (9.7 +/- 4.6) mm Hg and (4.8 +/- 3.1) mm Hg respectively (P < 0.05). The lower esophageal sphincter length ranged from 5 to 8 cm.

CONCLUSIONIntraoperative esophageal manometry helps determine the accurate myotomy length of myotomy on the esophageal and gastric sides of the gastroesophageal junction and provides valuable information for the Heller's myotomy.

Multiple measurements of nocturnal penile tumescence and rigidity (NPTR) are widely accepted as a method to differentiate psychogenic erectile dysfunction (ED) from organic ED. However, direct evidence remains limited regarding the first-night effect on NPTR measurement using the RigiScan. Here, we evaluated the first-night effect on the results of NPTR measurement to validate the necessity of NPTR measurement for two consecutive nights, particularly when abnormal first-night measurements are recorded in a laboratory setting. We retrospectively reviewed 105 patients with a complaint of ED, who underwent NPTR measurement using the RigiScan in the Department of Infertility and Sexual Medicine, the Third Affiliated Hospital of Sun Yat-sen University (Guangzhou, China), for two consecutive nights, during the period from November 2015 to May 2016. NPTR parameters were collected and analyzed. We found that more effective nocturnal erections were detected during the second night than during the first night (P <0.001). Twenty percent of all patients had no effective erection during the first night, but exhibited at least one effective erection during the second night. The negative predictive value of NPTR measurement during the first night was 43.2%; this was significantly lower than that on the second night (84.2%; P = 0.003). Most NPTR parameters were better on the second night than on the first night. The first-night effect might be greater among patients younger than 40 years of age. In conclusion, two consecutive nightly measurements of NPTR can avoid a false-abnormal result caused by the first-night effect; moreover, these measurements more accurately reflect erectile capacity, especially when the first-night record is abnormal in a laboratory setting.
