Objective To study the immunologic mechanism of electroacupuncture at Sanyin points on chronic abacterial prostatitis rats. Methods Forty-eight male rats were divided randomly into normal group, model group, drug group and electroacupuncture group, 12 rats in each group. The animal model was made by SC purified prostate protein twice with immunologic adjuvant, and the rats in electroacupuncture group and drug group were treated by electroacupuncture at Sanyin points and feeding Cernilton for 15 days. The changes of prostate weight, index, pathology and contents of IgG, expressions of IL-2 and IL-8 in prostate homogenate were observed. Results Compared with normal group, the prostate weight and index were significantly increased in model group (P<0.05), the content of IgG was significantly increased (P<0.05), cytokine IL-2 and IL-8 were highly expressed (P<0.05, P<0.01), prostate tissue’s morphology and structure were significantly impaired in model group. Compared with model group, the prostate weight and index were significantly decreased in electroacupuncture group after treatment (P<0.05 or P<0.01), pathological changes reduced significantly, the content of IgG decreased significantly (P<0.05), the expressions of cytokine IL-2 and IL-8 were significantly decreased (P<0.05, P<0.01), and the pathological manifestation of chronic inflammation was significantly improved. Conclusion Electroacupuncture at Sanyin points can reduce the secretion of local prostate antibody IgG, regulate the expression of cytokine IL-2 and IL-8, protect the morphology and structure of prostate tissue from damage. Electroacupuncture at Sanyin points can adjust local immunologic function and promote the recovery of prostate.

Objective To investigate the clinical features of neonatal invasive fungal infection(IFI) so as to guide diagnosis,prevention and treatment of IFI.Methods Seventy-six neonates with IFI admitted to the Neonatal Intensive Care Unit (NICU) at Children's Hospital of Fudan University from 2004 to 2014 were included in the study.Pathogens,clinical manifestation,risk factor exposure,laboratory findings,complications,and clinical outcome of neonatal IFI were analyzed.Results Seventy-six cases were diagnosed as IFI between 2004 and 2014,with an yearly increasing trend.Sixty-eight patients were premature infants (89.5％).Of the 76 cases,except one with unknown birth weight,11(14.7％),34(45.3％),20(26.7％)and 10 (13.3％) cases had birth weight ＜ 1 000 g,(≥ 1 000-＜1 500) g,(≥ 1 500-＜2 500) g and ≥ 2 500 g,respectively.The pathogens were mainly Candida (74/76,97.4％),including 26 cases of Candida albicans (34.2％).However,the incidence of non-Candida albicans infection was increasing.Candida guilliermondii was the most common in nonCandida albicans,accounting for 29.2％ (14/48).All Candida albicans were sensitive to fluconazole.One strain of Candida glabrata was resistant to fluconazole.The most common risk factors included use of broad-spectrum antibiotics(93.3％,56/60),parenteral nutrition(70.0％,42/60),central vein catheterization(53.3％,32/60),invasive ventilation(40.0％,24/60) and history of abdominal surgery(21.7％,13/60).Clinical manifestations of IFI included temperature instability,frequent apnea,increased requirement of respiratory support and feeding intolerance.Among all cases,six were diagnosed as central nervous system infection.Of the patients who received cranial MRI,46.8％(22/47) showed multiple abnormal signals in cerebral parenchyma.Fiftytwo patients were cured and seven patients died before discharge,including one death due to fungal infection.Conclusions There is an increasing trend of IFI cases in NICU,especially in premature infants.Non-Candida albicans has become the main pathogenic fungus.There are no specific clinical manifestations in neonatal IFI.Use of broad-spectrum antibiotics,parenteral nutrition and central venous catheterization are common risk factors,and preventive measures should be taken in high-risk infants.In addition,IFI in neonates may affect important organs such as central nervous system,thus early treatment is necessary in suspected patients.

Objective To understand the current situation of medical waste management in primary medical insti-tutions in China.Methods The management of medical waste in 95 primary medical institutions in 5 provinces of China in 2016 were investigated.Results Of 95 primary medical institutions,90(94.74%)dispose medical waste by centralized processing,92(96.84%)separately collect medical waste,89(93.68%)have specific locations for temporary waste storage and handover registration,46(48.42%)have wastewater treatment facilities,and are re-sponsible by full-time or part-time personnel.Before 2000,only 4 (4.21%)primary medical institutions carried out medical waste classification management and centralized disposal,which increased to 92(96.84%)and 90(94.74%) respectively in 2014;before 2000,only 5(5.26%)primary medical institutions conducted temporarily medical waste storage and treatment,which increased to 89(93.68%)in 2014.Conclusion Medical waste management in primary medical institutions has been improved significantly,but there still remain some problems,training relevant to waste management knowledge needs to be strengthened among health care workers,medical waste management procedures should be standardized,sound medical waste management and supervision system should be improved.

Objective To analyze the changes in peripheral blood monocyte subpopulations in patients with primary, secondary and latent syphilis. Methods Flow cytometry was used to detect CD14highCD16- and CD14+CD16+ monocyte subpopulations in peripheral blood from 58 patients with untreated syphilis, including 36 cases of latent syphilis,8 cases of primary syphilis and 14 cases of secondary syphilis, as well as from 65 normal human controls. Restflts Compared with the normal controls, the proportion of CD14+CD16+ monocytes among total monocytes was significantly elevated (12.0% ± 5.0% vs 6.0% ± 3.3%, t = 7.25, P < 0.01), while that of CD14highCD16- monocytes was down-regulated (88.0% ± 5.1% vs 94.0% ± 3.5%, t = -7.20, P < 0.01). No statistical difference was observed in the proportion of CD14+CD16+ or CD14hhighCD16- monocytes among the patients with primary syphilis, secondary syphilis and those with latent syphilis (all P > 0.05). Conclusions The changes in peripheral blood monocyte subpopulation in patients with untreated syphilis may be associated with the permanent infection of Treponema pallidum, but have no obvious correlation with clinical stage of syphilis.

Objective To explore the CT and MRI manifestations and diagnosis of elastofibroma dorsi(EFD).Methods CT or MRI findings of 20 cases (36 lesions)of EFD confirmed by surgical pathology were analyzed retrospectively.12 patients underwent plain chest CT,4 patients plain chest MRI,4 patients plain unilateral shoulder MRI.Results ① All of cases were located in the infrascapular region,between the thorax wall and serratus anterior,mainly shaped flat mound-like or semi-circular.CT densities and MRI signal intensities of the masses were similar to those of muscle with some interlaced fat-like areas within the lesions.The masses had irregular edges, with no clear boundary between the thorax wall and serratus anterior,with disappeared fat gaps.② Statistical difference were found in patients’incidence between men and women,incidence between unilateral and bilateral and lesion volume between the left and right (P <0.05),and the incidence in female was significantly higher than that in male,the incidence in bilateral was significantly higher than that in unilateral,the lesion volume in the right was bigger than that in the left.Conclusion ① EFD has its characteristic location and imaging findings,so a definite diagnosis can be made with CT and MRI.② The mechanical friction between the scapula and chest wall may be related to tumor growth.
