Objective To analyze the clinical characteristics, risk factors and prevention measures of nosocomial infection in senile patients with hematologic disorders. Methods The clinical data of 581 senile patients with hematologic disorders from July 2005 to June 2007 were retrospectively analyzed. Results The nosoeomial infection rate was 30.5%(177/581). The 581cases developed nosocomial infection for 254 times [43.7% (254/581)]. Lower respiratory tract infection was the most frequent infection site, followed by intestinal infection and upper respiratory infection. The species were predominated by Gram-negative bacillus (67.1%) . The risk factors of nosocomial infection were non-remission of malignant diseases,chronic underlying diseases, long time hospitaliation, community infection, granulocytopenia, invasive manipulation and application of adrenocortical hormone and antibiotic. Conclusions The nosoeomial infection rate is high in senile patients with hematologic disorders and it can be decreased by taking prevention measures according to the risk factors.

Objective To explore early diagnosis and treatment of congenital esophageal atresia and tracheoesophageal fistula.Methods Clinical data of 11 patients with congenital esophageal atresia and tracheoesophageal fistula were analyzed retrospectively.Definite diagnoses were made for all cases in 24 hours through making an esophagus opacification with acetrezoic acid or iodinated oil.And an esophagus anastomosis outside pleura was made.Some experience of diagnosis and therapy were summarized.Results All of the 11 cases underwent operation.Among them,9 cases were cured (81.8%),and 2 cases died(18.2%).Anastomosis stenosis of esophagus was found in 1 case after operation,which was cured through esophagus dilatation.Tracheoesophageal fistula was found in another case after operation and it was cured through combined treatment including anti-infection, nutritional support and sufficient draining.Conclusion Early diagnosis and surgical treatment, postoperative care,prevention and cure of complication are very important to improve the survival rate of the patients with congenital esophageal atresia and tracheoesophageal fistula.

Background The diagnosis of central serous chorioretinopathy (CSC) is mainly dependent onfluorescine fundus angiography (FFA). However, the combination of optical coherence topography (OCT) with FFA offers a new approach to the research of the pathogenesis of CSC. Objective This clinical study was designed to study the combined application of the FFA and OCT for the research of the pathogenesis of central serous chorioretinopathy (CSC). Methods Forty-four eyes of 44 patients with CSC were included in this study with 36 cases of males and 8 cases of female. The patients were aged 39.3 ± 5.3 years and the visual acuity was 0. 64 ±0. 27. FFA and OCT examinations were performed in all patients and the FFA images were imported into the Topcon 3D OCT 1000 device to locate the conformity of OCT lesions with the leakages of FFA. The neuroepithelial layer thickness at the fovea and the height of the neuroepithelial layer detachment were measured using 3-D OCT. Results OCT showed serous REP detachment in 34 eyes (77.3%) and rough surfaces of RPE in 10 eyes (22. 7% ). In thirtyfour eyes with RPE detachment, the OCT lesions and FFA leakage spots conformed to the same locations in 31 eyes, but the other three eyes did not. The mean foveal neuroepithelial thickness was (138.5±19.4) μm in CSC eyes and that of normal eyes was ( 131.35±5. 01 ) μm ,showing a significant difference between them( t=0. 39 ,P＞0. 05 ). The mean height of neuroepithelial detachment was (263.3 ± 126.7 ) μm in CSC eyes. Conclusion RPE detachment occurs in CSC eyes and further induces macular neuroepithelial detachment. Leakage lesion of fluorescine corresponds to RPE detachment. CSC without RPE detachment may be related to the increase in RPE permeability. OCT can accurately measure the thickness of the macular neuroepithelial layer and the height of the neuroepithelial detachment.

OBJECTIVETo analyze the characteristics of injuries between two types of Emergency Department (ED) in China.

METHODSWe selected 25 hospital EDs in the whole country as spots for investigation, and designed one special questionnaire to collect information, from 1st July, 2001 to 30th June, 2002.

RESULTSIn city hospitals (CIH), the proportion of injury to all diseases were 19.65%, and in country hospital (COH) it was 29.88%. The fatality rate of injuries was 1.29% in COH, which was higher than that of CIH's (P < 0.001). In COH, ambulance was more frequently used to treat injury patients than in CIH, but the average rescue time was not different. In cities, machinery was the leading cause (about 32.88%), but in country it was due to transpert (35.34%). Traffic accidents, suicide/homicide and unintentional drowning were the main causes of death. In CIH, the number of unintentional poisoning was almost twice as intentional, but in COH the patients due to poisoning suicide act were more than unintentional poisoning, with 2/3 of the poisoning causes were women. Patients due to chemical, drug and food poisoning accounted for 86.13% in CIH, while in COH the main causes were pesticidal, chemical and druggery (89.80%). In all poisons, pesticide was the leading cause for death.

CONCLUSIONIt's suggested that patients with injury be treated timely since the acute injury patients accounted for important part of ED's patients. The differences between CIH and COH were obvious, with better ability of treatment in CIH than in COH. More relevant measures were needed to improve the ability of acute treatment for injuries.

OBJECTIVEThis study aimed to develop an estimate of the actuality and characteristics of poisoning suicide attempted patients in emergency department (ED) in China.

METHODSWe selected 25 hospital EDs in whole country as the investigation spots, and designed one special questionnaire to collect information from the poisoning suicide attempted patients from 1st July, 2001 to 30th June, 2002.

RESULTSResults were based on 4060 cases hospitalized during the investigating period. In general frequency analysis, the ratio of male to female was 1:2.95. In all patients, 98.40% cases took poisons orally, and 93.57% cases occurred at home. The average age was 31.5 years old (min 8, max 93). The leading occupations of cases were farmers, unemployed house-wives, jobless, service people and students. The main types of poisons were druggery (54.29%) and pesticide (35.84%). 2044 cases (59.23%) were cured timely (in 1 hour). When comparing cases from rural hospitals (RHs) and urban hospitals (UHs): ratio of poisoning attempted suicides in RHs to all poisoning cases was higher than UHs with significant gender difference (P < 0.05). UHs number one cause of poisoning was druggery, but in RHs it was pesticide.

CONCLUSIONPoisoning attempted suicide was very serious in China. Farmers and women were among the high-risk groups. Druggery and pesticide were the primary poisons, suggesting that management enforcement was in urgent need.

OBJECTIVETo Assess therapeutic effect of ear point taping and pressing therapy combined with acupoint-injection on residual neuralgia of herpes zoster.

METHODSOne hundred and sixteen cases were randomly divided into a comprehensive group (n = 60) and a medication group (n = 56). The medication group were treated with routine western medicine, and the comprehensive group with ear point taping and pressing therapy combined with acupoint-injection besides the routine western medicine. Auricular points selected for ear point taping and pressing were Shemen, Neifenmi (endorine), Pizhixia (subcortex), Gan (liver), Dan (gallbladder), Fei (lung) and corresponding auricular points to the lesion parts, with the two ears alternatively used, pressing each day; points selected for point-injection of VitB12 were Zusanli (ST 36), Neiguan (PC 6), Quchi (LI 11), Taichong (LR 3). The pain degrees, the time of pain alleviation and pain ceasing of the patient were regularly recorded.

RESULTSThe average time of pain alleviation and pain ceasing of the patient in the comprehensive group were significantly shorter than those in the medication group (P < 0.01). The cured rate and the cured and markedly effective rate were 60.0% and 83.3% in the comprehensive group, and 28.6% and 50.0% in the medication group, with significant difference between the two groups (P < 0.05).

CONCLUSIONEar point taping and pressing therapy combined with acupoint-injection is effective and safe for treatment of residual neuralgia of herpes zoster.

OBJECTIVETo explore the regulatory effect of clearing-Heat secreting-bile regulating-Qi flow and activating blood circulation (CSRA) principle on cholecystokinin receptor (CCK-R) and its mechanism.

METHODSCholecystokinin (CCK) in serum of portal venous blood, maximum binding capacity (Bmax) and affinity (Kd) of CCK-R levels in gallbladder of guinea pigs allocated in four groups (control, high cholesterol, natural recovery and treated groups) were determined using radioimmunoassay and radioligand receptor assay (RRA). At the same time, changes of fasting volume (FV) and postprandial volume (PV) of gallbladder, fasting and postprandial bile (FB and PB) in gallbladder, gallbladder contraction rate (GCR) and cholesterol concentration (CC) in bile were observed.

RESULTSCompared with the control group, after two weeks of high cholesterol feeding, increase of FV, FB, PV, PB and CC (P < 0.05), and decrease of GCR (P < 0.01) and Bmax were found in cholesterol group, but with no significant change in Kd and CCK level. The above-mentioned criteria were restored to normal range in the treated group.

CONCLUSIONCSRA principle could promote the recovery of gallbladder contraction by regulating CCK-R expression in it, its mechanism is possibly correlated with reduction of cholesterol concentration in bile.
