Objective To investigate the causes of ectopic pregnancy misdiagnosis.Thus we can increase the rate of early diagnosis and avoid complications that could threaten life.Methods 48 cases which were misdiagnesed were retrospectively analyzed.Results Of the 48 cases,28 cases were misdiagnosed as intrauterine pregnancy,accounting for 58.3%,of which 16 cases were early pregnancy;12 cases were threatened abortion;7 cases were acute inflammation annex;6 cases were acute appendicitis;2 cases were acute gastroenteritis;3 cases were corpus luteum rupture;and 2 cases were dysfunctional uterine bleeding.Conclusion The complicated clinical manifestation of ectopic pregnancy makes misdiagnosis easy to happen.In order to reduce the rate of misdiagnosis,clinical practitioners should strengthen the professional quality,make a detailed inquiry on the history of illness and inspect carefully.

Objective To analyze the changes of primary disease and demography of patients with end-stage renal disease (ESRD) who started dialysis between 2008 and 2013 in Zhejiang province, in order to provide statistical support for the improvement of dialysis quality.Methods The study retrospectively reviewed all the incident ESRD patients on dialysis registered in Zhejiang Dialysis Quality Control Center from 2008 to 2013.Their demographics and primary cause were investigated.Stratified analysis based on dialysis modality, duration and age were conducted.Results A total of 26 310 incident ESRD patients who started dialysis between 2008 and 2013 in Zhejiang were selected, among which 14 886 cases were male and 11 424 cases were female (male: female: 1.30: 1).The study gave priority to patients aged 45 and above (73.9％), with an average age of (55.7± 16.1) years.The top primary disease was chronic glomerulonephritis (51.3％), followed by diabetic nephropathy (17.3％) and hypertensive nephrosclerosis (6.4％).From 2008 to 2013, the incidence of dialysis was 46.3, 60.1, 71.2, 85.8, 104.1, and 119.9 per million population respectively.The average age of patients was increased year by year, from 52.4, 53.3, 54.8, 56.0, 56.9, to 57.6 years.The share of peritoneal dialysis, as well as the promotion of diabetic nephropathy in primary disease was on the rise.With the increase of age, the proportion of primary diseases such as diabetic nephropathy and hypertension nephrnsclerosis was increased.Conclusions In Zhejiang province, incident dialysis patients increase annually.More males than females are on dialysis.The average age and proportion of peritoneal dialysis are rising.The leading cause is chronic glomerulonephritis, but the incidence of diabetic nephropathy is on the increase, which requires attention.

OBJECTIVETo investigate the morphology and proliferation effects of adenovirus containing bone morphogenetic protein-2(BMP-2) on tongue cancer Tca8113 cells.

METHODSTca8113 cells were transfected with the Ad-BMP-2 of 0, 50, 100 multiplicity of infection (MOI) respectively. Inverted fluorescence microscope was used to evaluate the morphological changes of these cells. Western blot analysis was performed to determine the expression levels of BMP-2 in the transfected cells. Methyl thiazolyl tetrazolium (MTT) assay was performed to monitor the proliferative activity of the infected Tca8113 cells and then the growth curve was made.

RESULTSThe transfection efficiency reached the highest when the MOI was 100. Moreover, the expression of BMP-2 was detected in Tca8113 cells by Western blot. There were no obvious morphological changes of the Tca8113 cells before and after transfection. And the proliferation of transfected Tca8113 cells decreased compared with control.

CONCLUSIONAd-BMP-2 gene can inhibit the proliferation of Tca8113 cells in vitro.

Objective To investigate the effectiveness and safety of oral olive oil combined with polyethylene glycol electrolyte ( PEG ) on bowel preparation before colonoscopy for chronic constipation patients. Methods A randomized, single-blind, prospective study was conducted on 180 patients with chronic constipation, who underwent colonoscopy at Tangdu Hospital of the Fourth Military Medical University from November 2017 to May 2018. Patients were randomly divided into three groups. Patients in group A took 60 mL olive oil and a piece of crystal sugar at 7:30 pm the day before colonoscopy, followed by 1500 mL PEG at 8:00 pm before the test, and 1500 mL PEG at 5:00 am the day of colonoscopy. Patients in group B took 60 mL olive oil and a piece of crystal sugar after administration of PEG at 8:00 pm the day before colonoscopy, followed by 1500 mL PEG at 5:00 am the day of colonoscopy. The group C was given 1500 mL PEG at 8:00 pm the day before colonoscopy, and another 1500 mL PEG at 5:00 am the day of colonoscopy. We recorded the time of first defecation after taking medication, the number of defecation before sleep, the total number of defecation, the score of Boston bowel preparation scale ( BBPS) of the right, middle and left colon, and the adverse reactions, and compared the data among the three groups. The measurement data was compared using the analysis of variance. After the difference was found, the LSD-t test was used to compare between the two groups. The enumeration data was compared using the Pearsonχ2 test. Results One patient in the group B terminated colonoscopy due to unable to continue cooperation during the examination. Group B and C both excluded one patient because of a large mass found in the descending colon of patients. Finally, there were 60 cases in the group A, 58 in the group B, and 59 in the group C. There was no statistical difference between the three groups in the general resource ( P>0. 05) . The time of first defecation after taking medication for the group A, B and C was (2. 25±2. 32) h, (2. 43±2. 39) h and (3. 36±2. 79) h respectively, with statistical difference (F=3. 36, P=0. 037). The time of first defecation was longer in the group C than that of the group A and B ( P = 0. 016 and P = 0. 046, respectively). The number of defecation before sleep for the group A, B and C was 3. 47±2. 09, 3. 24±1. 76 and 2. 49±1. 58 respectively, with statistical difference (F=4. 65, P=0. 011). The number of defecation before sleep was lesser in the group C than that of the group A and B ( P=0. 004, P=0. 027, respectively) . The total number of defecation for the group A, B and C was 7. 20 ± 2. 67, 6. 81 ± 2. 31 and 5. 64 ± 2. 22 respectively. The difference among the three groups was statistically significant ( F=6. 68, P=0. 002) . For the group A and B, the total number of defecation was both more than that of the group C ( P=0. 001, P=0. 010) . There were no statistical differences among the three groups in the BBPS score of the left and middle colon and the total BBPS score ( all P>0. 05) . The BBPS score of the right colon for the group A, B and C was 2. 03 ± 0. 82, 1. 95 ± 0. 87 and 1. 53 ± 0. 80 respectively, with statistical difference ( F=6. 38, P=0. 002) , and was lower in the group C than that of the group A and B ( P= 0. 001, P= 0. 006, respectively) . Adverse reactions after taking medication including nausea, vomiting, abdominal pain, and bloating were respectively reported in 7, 3, 0 and 3 cases in the group A, 5, 3, 0 and 6 in the group B, and 4, 2, 1 and 4 in the group C, and there was no statistical difference among the three groups (χ2=4. 35, P=0. 824) . Conclusion Administration of olive oil compared with PEG can improve the cleanness of right colon for chronic constipation patients, shorten the time of first defecation after taking medication, and increase the number of defecation before sleep and the total number of defecation during bowel preparation. Taking olive oil before or after PEG at the night before colonoscopy has no significantly effect on bowel preparation and adverse reactions.
