ObjectiveTo evaluate the reasonableness of total mesorectal excision (TME) in the management of rectal cancer. Methods The carcinoembryonic antigen (CEA) level of surgically removed distal mesorectum (3?cm below the tumor),tumor tissue and normal mesocolon was detected by microparticle enzyme immunoassay in 26 rectal cancer patients. Results The CEA level in normal mesocolon was (1.6?1.0)?ng/g, and (62.5?85.2)?ng/g in distal mesorectum(P1?000?ng/g).ConclusionsIn patients with rectal cancer, much higher CEA level in distal mesorectum than in normal mesocolon might indicate distal mesorectal dissemination. It is necessary to routinely perform TME in the surgical management of middle and lower rectal cancer.

Objective To evaluate the treatment methods of endophthalmitis after IOL implantation. Design Retrospective case series. Participants 15 patients with endophthalmitis after IOL implantation treated by Beijing Xuanwu Hospital in 2002-2008. Meth-ods Vancomycin was injected into vitreous cavity in all patients. Vitrectomy was performed on the patient whose infective bacteria could not be controlled by intravitreal injection. Main outcome measures Infective status, visual function, results of microbiological exami-nation. Result Endophthalmitis occured in 13 cases (86.6%) after 72 hours of cartaract surgery. Microbiological examination was per-formed on 15 cases (aqueous or vitreous sample), 6 cases showed positive results, in which 4 cases were staphylococcus epidermidis. The infection of 12 patients (80%) were controlled with intravitreal injection and 10 patients gained final visual acuity better than 0.1. Three patients received vitrectomy because infective bacteria can not be controlled. Conclusion Staphylococcus epi. may be the major cause of subacute endophthalmitis after cartaract surgery. Antibiotics injected immediately into vitreous cavity can control the infections in most cases.(Ophthalmol CHN, 2009, 18: 270-272)

Objective To understand the causes and the ratio of cause constituents in children with chronic cough in Beijing. Methods Patients with chronic cough treated at respiratory clinic of the Children' s Hospital Affiliated to Capital Institute of Pediatrics from May 2009 to April 2011 were included in this study. Etiologic diagnostic procedure suggested for children by the Subspecialty Group of Respiratory Diseases,the Society of Pediatrics,Chinese Medical Association in 2008 was implemented to manage the patients. After three - month follow - up,the etiological data was analyzed. Results Totally 213 patients with chronic cough aged 1. 1 to 14. 0 years old were enrolled,inclu-ding 40 cases(18. 8% )aged≤3 years old,134 cases(62. 9% )aged ﹥ 3 to 6 years old,and 39 cases(18. 3% ) aged ﹥ 6 years old. The majority of patients with positive allergen tests were sensitized to inhaled allergens. One child had positive result in 24 - hour esophageal pH monitoring,but his cough didn't respond well to the specific treatment for gastroesophageal reflux,so he wasn't diagnosed as gastroesophageal reflux cough. The 4 leading causes of the 213 pa-tients with chronic cough were cough variant asthma(CVA)in 92 cases(43. 2% ),CVA associated with upper airway cough syndrome(UACS)in 57 cases(26. 8% ),UACS in 28 cases(13. 2% ),respiratory infection and post - infec-tion cough(PIC)in 26 cases(12. 2% ),while other causes were found in 8 cases(3. 7% ),and unknown etiology in 2 cases(0. 9% ). The incidence of CVA ranked top 1 in all the 3 age groups,followed by PIC in ≤3 years old group, while CVA associated with UACS in the other 2 age groups. Conclusions CVA,CVA associated with UACS,UACS and PIC were the 4 leading causes for children with chronic cough in Beijing. Children in different age groups had dif-ferent constituents ratio of causes of chronic cough.

Objective To learn the exposure levels and health hazards of long-term exposure to hexavalent chromium (Cr6+) through drinking water in a west county,and to provide a scientific basis for making preventive measures.Methods Five water points were selected to test the Cr6+ concentration of drinking water in the county in 2015,data of 3 water points with water Cr6+ concentrations exceeded the standard (Cr6+ ＞ 0.05 mg/L) were selected from 12 drinking water points in some west counties in the recent six years (2009-2014) as the exposed group,2water points that drinking water Cr6+ concentrations not exceeded the standard (Cr6+ ≤0.05 mg/L) in the county and adjacent to the exposed group were selected as the control group.Sixty villagers were selected as the investigation objects in each water point to conduct internal medicine,ears,nose,throat (ENT),dermatology and health examination,urinary chromium content,routine blood and urine test were done.Determination of hexavalent chromium concentration in drinking water was done according to The Drinking Water Standard Examination Method 1,5-diphenylcarbazide Spectrophotometry (GB/T 5750-2006);routine urine was tested using the 10 urine analyzer test;urinary chromium was tested using graphite furnace atomic absorption spectrometer;routine blood five classification was tested using automatic blood analyzer;determination of drinking water hexavalent chromium concentration was done according to The Hygienic Standard for Drinking Water (GB 5749-2006).Higher than 0.05 mg/L was judged as exceeded the standard;physical examination was done according to The Diagnostic Criteria of Occupational Chromium Nasal Disease (GB Z12-2002) and The Diagnostic Standard of Occupational Contact Dermatitis (GB Z20-2002).Results There were 184 and 109 people in the exposed group and the control group,respectively.The average concentration of Cr6+ exceeding the standard ratio was 2.82-3.22 in drinking water,the nasal septum nucosa perforation,skin erythema edema,skin ulcers were 4.9％ (9/184),4.3％ (8/184) and 4.3％ (8/184) in the exposed group,and the urinary chromium level (0.31 μg/L) in the exposed group was significantly higher than that of the control group (0.27 μg/L,Z =-4.078,P ＜ 0.05).Routine blood test result of mean corpuscular haemaglobin (MCH) was (29.56 ± 2.07) pg,platelet counts (PLT) was (222.38 ± 47.53) × 109/L and plateletcrit (PCT) was (0.25 ± 0.05)％ in the exposed group,it was all higher than those of the control group [(29.03 ±2.95) pg,(211.74 ±75.27)× 109/L,(0.24 ± 0.08)％,t =1,940,2.318,2.079,all P ＜ 0.05];standard difference coefficient of variation of red blood cell distribution width (RDW-CV) was (13.14 ± 1.05)％,lymphocyte number (LYMPH) was (2.01 ± 0.64) × 109/L in the exposed group,it was all lower than those of the control group [(13.38 ±1.54)％,(2.21 ± 1.02) × 109/L,t =-1.989,-1.956,all P ＜ 0.05].The positive rate of glycosuria,uric bravery red,and urine nitrite in routine urine test of exposed group was 17.39％ (32/184),23.36％ (43/184),7.61％ (14/184);it was all higher than those of the control group [(8.25％ (9/109),11.93％ (13/109),0.91％ (1/109),x2 =4.746,5.798,6.309,all P ＜ 0.05].Conclusions Urine chromium accumulation has been found in populations long-term exposed to 2.82-3.22 times excessive Cr6+ through drinking water,which has affected the population's health to some extent.Therefore,it is necessary to speed up the local drinking water improvement project.
