Chinese Journal of Nosocomiology 2009;0(15):-
OBJECTIVE To investigate and analyze the hospital infection in 32 hospitals throughout the county,in order to reduce hospital infection. METHODS According to new Hospital infection administration regulations and medical service hospital infection control quality evaluation requirements,we had investigated and analyzed and guidanced to improve the hospital infection management in 32 hospitals of the county for a two-years. RESULTS The monitoring,surveillance and management of hospital infection in grass-roots hospitals as a quality evaluation index of hospital medical service still had many problems,After two years,it had been more improved the quality in the field of administration management,sterilization and disinfection,surveillance and sevage treatment. CONCLUSIONS According to Hospital infection administration regultions it is important to strengthen the hospital infection management for guaranteeing the grass-roots hospital medical service quality and medical care safety.

Objective To review recent studies on Muir Torre syndrome (MTS) and to improve the knowledge about MTS.Methods The literatures in recent years on clinic and gene research of MTS were reviewed.Results MTS was is a rare autosomal dominant disorder characterized by the predisposition to both sebaceous tumors (or multiple keratoacanthomas) and internal malignancies. Gastrointestinal cancers were the most common kind of internal malignancies in MTS patients(61%),followed by genitourinary cancers(22%). In most cases(56%),sebaceous tumors appeared after the emergence of internal maliganancy. Both hereditary nonpolyposis colorectal cancer(HNPCC) and MTS were caused by germline mutations in the DNA mismatch repair genes. MTS patients exhibit significantly more mutations in the hMSH2 than in the hMLH1. In these cases , both internal and skin tumors showed the characteristic of high microsatellite instability(MSI).Conclusion The presence of sebaceous tumors(or multiple keratoacanthomas) necessitates the search for internal malignancies. It is mandatory that patients with MTS, as patients with HNPCC, should be regularly followed up to search new malignancies. Evaluation and monitoring of the family members of patients are also necessary. The patients and their families should be counseled for genetic test. Sequencing the hMSH2 gene should be the prior selection of further examinations when clinical manifestations, history and laboratory tests suggest MTS.

The JC virus is a widely infected human polyomavirus. Recent foreign researches showed that the JC virus infection is correlated with tumors of nervous system and digestive system, while, and study on the relationship between JC virus infection and gynecological tumor is seldom reported. In this study, we first establish the nucleic acid detection methods and procedures for JC virus and its highly homologous BK virus. The JC and BK viruses infection was evaluated by detect the viral DNA in samples including biopsy tissues, serum as well as urine of myoma of uterus (98 cases), cervical cancer (84 cases), endometrial cancer (40 cases) and ovarian tumor (72 cases) patients. The BK viral DNA positive rate was significantly higher in urine samples than that of blood and biopsy samples, and there is no significant difference of the BK viral DNA positive rate among all patient groups. The JC viral DNA positive rate is almost 0 in serum samples and biopsy. tissues, however, viral DNA positive rate is more than 50% in urine samples. In fibroids group, the JC viral DNA positive rate is up to 65. 3% which is significantly higher than that in other patients groups and healthy control. Further gynecological tumor associated viruses detection showed that only human papilloma virus infection is associated with cervical cancer, the herpes simplex virus, EB virus and cytomegalovirus infection is extremely low in our patient groups. No synergistic effect on gynecological tumor caused by viruses co-infection was observed. Our study showed that JC virus infection is highly related to the pathogenesis of uterine fibroids.

Objective To determine the significance of change of insulin-like growth factor-1(IGF-1) and study the effect of IGF-1 on expression of Bcl-2 and Bax.Methods Male Balb/c mice were randomly divided into control group,coxsackie B3(CVB3) infection group(infection group),CVB3 infection with IGF-1 treated group.Animals were killed at d7,d14.The immunohistochemical studies and medical imagine analysis system were performed to evaluate the expression of Bcl-2 and Bax in myocardial tissue.Serum IGF-1 concentrations were assayed by radioimmunoassay(RIA).Results In infection group,the concentrations of IGF-1 were more decreased than that of control group and the expression of Bcl-2 reduced and Bax increased(P

AIM:To observe the clinical curative effect of different duration of retinal vein occlusion ( RVO ) by laser photocoagulation treatment, discuss the timing of the RVO laser photocoagulation treatment, provide the basis for clinical choice of RVO photocoagulation treatment time.
METHODS: Retrospective analysis. Line selection retinal laser photocoagulation treatment for 103 cases (103 eyes) with RVO, patients were divided into three groups according to the onset time. In group A (46 eyes), course≤ 1mo, 28 eyes with branch retinal vein occlusion ( BRVO ) , 18 eyes with central retinal vein occlusion ( CRVO);30 eyes were ischemic RVO, 16 eyes were non-ischemic RVO. In group B (38 eyes), 1mo
CONCLUSION:RVO laser photocoagulation in the early intervention treatment can accelerate the retinal hemorrhage, macular edema, absorption, effectively protect the patient's existing vision, improve the long-term vision, and has a certain clinical practical significance.

AIM:To introduce a new method of guiding by using 3D-OCT to treatment central serous chorioretinopathy ( CSCR) with multiwavelength laser.
METHODS:Twenty-three cases ( 23 eyes ) typicality central serous chorioretinopathy were collected in July 2010 to July 2013 in Changchun Aier Eye Hospital, using 3D-OCT model locate central serous chorioretinopathy leakage point and photocoagulation treatment with multiwavelength laser. Postoperative follow-up of 24wk, the postoperative vision and macular area retina neuroepithelial layer detachment height were observed.RESULTS: Twenty-three cases ( 23 eyes ) of central serous chorioretinopathy patients by the 3D-OCT guided multiwavelength laser treatment vision after 24wk of follow-up compared with before treatment. there was statistically significant ( P < 0.05 ) . Visual improved obviously after treatment. OCT macular area before and after the treatment on macular area retina neuroepithelial layer detachment height ( P<0.05 ) . OCT macular area before and after the treatment of macular area retina neuroepithelial layer detachment height significantly decreased, slurry apparent absorption. Except 1 case lost visitors, 23 cases ( 23 eyes ) with central serous chorioretinopathy did not see the whole body or eye local adverse reactions occur.
CONCLUSION: 3D- OCT guided by multiwavelength laser treatment of central serous chorioretinopathy and under the guidance of FFA in the central serous chorioretinopathy laser treatment have the same curative ratio, has certain clinical value.
