BACKGROUND: The purpose of our study is to evaluate the usefulness of cervicovaginal fetal fibronectin assay for the prediction of rupture of membrane and preterm labor. METHODS: A group of 39 pregnant women was involved in this prospective study. Out of 139 pregnant women, 96 were clinically diagnosed as ruptured membranes (group A). The remaining 43 of 139 pregnant women were clinically diagnosed as preterm labor(group B). The assay was performed by using the ROMCheckTM kit (Adeza Biomedical Corp., Sunnyvale, CA). RESULTS: In group 4, fetal fibronectin (fFN) positive rate is 55% (53 patients) and negative rate is 45% (43 patients). In group B, fFN positive rate is 56% (24 patients) and negative rate is 44% (19 patients). Both group of fFN positive patients show a significantly shorter interval from sampling to delivery than fFN negative patients. Also in group A, the percentage of fFN positive patients who delivered at less than 48 hours after sampling is greater than those with fFN negative patients and in group B, the preterm delivery rate is 79% with positive fFN and 37% with negative fFN. As a predictor for preterm delivery, the presence of fFN has the sensitivity 79%, the specificity 84%, the positive Predictive value 76% and the negative predictive value 86%. CONCLUSIONS: The result suggests that a positive fFN in pregnant women who have uterine contractions and ruptured membrane indicates a significant risk for preterm delivery and labor onset, and a negative fFN is a reassuring sign.

Adenoid basal cell tumor of the prostate is a rare tumorous lesion that can be misdiagnosed as adenocarcinoma of the prostate. The malignant potential of adenoid basal cell tumor remains uncertain due to small number of reported cases. This 66-year-old man presented with symptoms of urinary tract obstruction. Under the impression of benign prostatic hyperplasia, a transurethral resection of the prostate (TURP) was performed. The patient was alive with no evidence of recurrence or metastasis 15 months after TURP. Microscopically, most of the lesions were composed of nodular collections of small nests of basaloid cells with peripheral palisading, and clusters of tumor cells forming cribriform pattern. Multiple areas of basal cell hyperplasia and atypical basal cell hyperpalsia were also observed. The coexistence of basal cell hyperplasia, atypical basal cell hyperpalsia, and adenoid basal cell tumor with cribriform pattern in this case supports a morphologic continuum from the benign hyperplastic lesion to malignant neoplasia.

A small scale survey was performed to know the infection status of intestinal parasite in children of the residential institutions and street communities in Metro Manila, Philippines. A total of 284 stool samples from 11 institutions and 3 street communities was examined by the formalin-ether concentration method. The scotch tape anal swab was adapted to 121 children to investigate the infection status of Enterovius vermicularis. It was found out that 62.0% of the children examined were positive for one or more intestinal parasites. Multiple infections were observed in 34.2% of the children. Among 172 children who gave detail information, the prevalence for Ascaris lumbricoides, Trichuris trichiura, and hookworm was 36.0%, 44.8%, and 7.0% respectively. Of the children examined, 47.7% were found to be harboring parasitic protozoans such as Entamoeba histolytica, Giardia lamblia, and Blastocystis hominis. The most prevalent of these protozoans was B. hominis with an infection rate of 40.7%. The prevalence of these infections among children living in institutions was relatively high. More efforts should be made to implement anthelminthic programs including bi-annual follow-up treatments.

BACKGROUNDEpidemiological study showed that the use of angiotensin-converting enzyme inhibitors was associated with higher bone mineral density (BMD) in older people, especially male subjects, which suggested that angiotensin II may have a detrimental effect on bone. Therefore, blocking its effect may have a beneficial effect on bone health.

METHODSSix-month-old male spontaneously hypertensive rats (SHR) and normotensive Wistar Kyoto rats (WKY) were used. Animals of each model were randomly assigned to the following four groups: Group 1, SHAM operated+vehicle; Group 2, orchidectomy (ORX)+vehicle; Group 3, ORX+low-dose losartan (10 mg×kg(-1)×d(-1)); and Group 4, ORX+high-dose losartan (25 mg×kg(-1)×d(-1)). Blood pressure was recorded weekly. SHAM and ORX operations were performed, followed by daily losartan and vehicle treatment from day 4 after operation for 16 weeks. Serum and 24-hour urine samples were collected for measurement of bone turnover markers before euthanasia and then the left femur was collected for measurements of BMD and microarchitecture before mechanical test.

RESULTSUrine deoxypyridinoline/urine creatinine (DPD/Cr) ratio was significantly higher in SHR than in WKY. BMD and microarchitecture parameters also showed bone deterioration in SHR. After ORX, serum osteocalcin concentration decreased and urine DPD/Cr ratio increased significantly accompanied by a significant decrease in cortical and trabecular BMD and cortical bone thickness in both WKY and SHR. High-dose losartan significantly increased DPD in urine in both SHR and WKY. Apart from marginal favorable changes in bone architecture in WKY treated with high-dose losartan, losartan did not show significant effect on BMD, bone area, bone microarchitecture, and mechanical properties in both SHR and WKY.

CONCLUSIONAngiotensin II type I receptor blocker losartan was not able to demonstrate significant effect on ORX-induced bone deterioration in both hypertensive and normotensive rats.

Objective: To analyze the effect of colorectal cancer screening in the general population in Guangzhou, and provide evidence for the for development of colorectal cancer screening policy and strategy. Methods: The data of colorectal cancer screening in Guangzhou during 2015- 2016 were collected. The participation, the positive rate of fecal occult blood test, the detection rate of colonoscopy and screening effect of colonoscopy were evaluated. Results: A total of 220 834 residents aged 50-74 years received the screening, and the positive rate of the screening was 16.77% (37 040 cases). Colonoscopy was performed for 7 821 cases (21.12%). Colorectal lesions were found in 4 126 cases (52.76%), of which 614 (7.85%) and 73 (0.93%) and 230 (2.94%) were identified as advanced adenoma, severe dysplasia lesions and colorectal cancers, respectively. The detection rates of all colorectal lesions were higher in men than in women (all P<0.01). The diagnostic rate of early lesion was 87.24%, and 99 early cancer cases were found, accounting for 46.26% of the total cases. The overall screening detection rate of colorectal cancer was 104.15/100 000, higher than the incidence rate (81.18/100 000) in colorectal cancer surveillance (P<0.001), but age group <70 years had higher detection rate, age group ≥70 years had higher incidence rate. Conclusions: The colorectal cancer screening strategy in Guangzhou is effective in the detection of the population at high risk, increase the detection rate of colorectal lesions, early diagnosis rate of precancerous lesions and diagnosis rate of early colorectal cancer. The benefit in those aged ≤69 years was more obvious than that in those aged 70-74 years. It is necessary to improve the compliancy of colorectal cancer screening in population at high risk.

Objective: To understand the status, attitude and related risk factors on smoking among 18-65 years old patients with hypertension, diabetes, dyslipidemia, chronic obstructive pulmonary disease (COPD) or asthma in Beijing. Methods: Data was gathered from the 2014 Beijing Non-communicable and Chronic Disease Surveillance Program. Multiple classified cluster sampling method was used and 19 815 participants aged 18-65 were sampled from 16 districts in Beijing. Results: Among all the 18 405 participants, male hypertensive patients showed a higher rate on current smoking than the other groups (χ(2)=17.695, P<0.001). Male patients with dyslipidemia had higher current smoking rate than the other groups (χ(2)=39.292, P<0.001). However, female patients with COPD or with asthma showed higher rate on current smoking than the other groups (χ(2)=6.276, P=0.012), (χ(2)=8.245, P=0.004). Among the smokers, hypertensive patients presented lower rate (χ(2)=20.487, P<0.001) on intention of smoking concession, than the other groups. Patients with COPD showed greater intention in quitting smoking (χ(2)=6.085, P=0.048), than the other groups. Male patients with diabetes (χ(2)=9.219, P=0.010) or dyslipidemia (χ(2)=13.513, P=0.001) who had stopped smoking tobacco appeared having higher rates in keeping the current status. Results from logistic regression analyses showed that smoking was the risk factor for hypertension (OR=1.17), dyslipidemia (OR=1.25), COPD (OR=1.78), and asthma (OR=1.57). Conclusions: Patients with certain kinds of chronic diseases showed higher rate of current smoking and lower rate of quitting. Cigarette consumption appeared an important risk factor for patients with hypertension, dyslipidemia, COPD, or asthma in Beijing.

Objective: To analyze the trends on mortalities of all-cause and deaths caused by chronic and non-communicable diseases (NCDs) among Chinese labor force population during 2007 to 2016. Methods: Data on cause-of-death that collected from the National Mortality Surveillance System was used to analyze the age and area-related specific crude mortality rates, age-standardized mortality rates and component ratios of NCDs, among the Chinese labor force population, during 2007 to 2016. Trend of crude mortality rates and mortality component ratios of the three major diseases (infectious diseases, maternal and infant diseases, nutritional deficiency diseases; NCDs; injuries) were analyzed. Age-standardized mortality of cancer, COPD, cardiovascular and cerebrovascular diseases were also analyzed by gender. Age-standardized mortality was calculated based on the Year 2010 Population Census of China. Joinpoint regression model was used to obtain annual percentage change and 95%CI was set for assessing the trend. Results: In 2016, the age-standardized all-cause mortality rate was 217.23 per 100 000 among the Chinese labor force population, but decreased by -2.8% (95%CI: -3.8%- -1.7%) annually from 2007 to 2016. The gap between different gender and regions gradually narrowed. The proportion of deaths caused by NCDs increased annually by 0.8% (95%CI: 0.7%-0.9%). The age-standardized mortality rate of NCDs appeared as 171.89/100 000, among the Chinese labor force population in 2016, showing a downward trend by -2.4% (95%CI:-3.3% - -1.4%). However, in females, there appeared the greatest decrease, with an average annual change of -3.3% (95%CI:-4.0% - -2.5%). Diseases as cancer, COPD, cardiovascular and cerebrovascular diseases all showed downward trends in the whole country, with an average range of -2.0% (95%CI: -2.6%--1.3%), -8.0% (95%CI: -8.9% - -7.1%), -1.5% (95%CI: -2.9% - -0.1%), -2.3% (95%CI: -2.8% - -1.8%) in a ten-year period, respectively. Conclusion: All-cause and age-standardized mortality rates caused by NCDs among Chinese labor force population were decreasing during 2007 to 2016. However, the constituent ratios appeared increasing, year by year. Close attention needs to be paid on NCDs which affecting the health of the labor force population in China.

BACKGROUND: Infrequent restriction site PCR (IRS-PCR) is a recently described DNA fingerprinting technique based on selective amplification of restriction endonuclease-cleaved fragments. We applied of IRS-PCR to clinical isolates of Vibrio parahaemolyticus associated with diarrhea. METHODS: IRS-PCR assay was performed with adaptors for XbaI and HhaI restriction sites. A total of 35 strains of V. parahaemolyticus which were isolated from clinical specimens of patients with diarrhea were analyzed. The isolates were collected from different geographic areas of Seoul (n=12), Incheon (n=21) and Gwangju (n=2) during 1998-2000 in Korea. RESULTS: In IRS-PCR, amplifed DNA fragments between 50 and 400 bp were found to be the most reproducible in this study. When V. parahaemolyticus isolates were amplified with AH1 and PX-G as primers, 35 isolates could be grouped into five IRS-PCR patterns: A (n=16), B (n=4), C (n=6), D (n=5) and E (n=4). The patterns were subdivided into 15 subtypes: A1, A2, B1, B2, B3, B4, C1, C2, C3, D1, D2, D3, E1, E2 and E3. The IRS-PCR patterns of V. parahaemolyticus did not show any relationship with serotype or geographic origin, but the isolates from same outbreak produced a same pattern(A1). CONCLUSION: The results provide evidence of the discriminatory power of the IRS-PCR method as it applies to V. parahaemolyticus.

Campylobacter fetus subsp. fetus is a rare human pathogen, but can cause serious extraintestinal infections. Effective antimicrobial agent is required for the therapy, but we have very limited knowledge on the susceptibility of the organism. In this study, the susceptibility of 25 isolates of the organism to 14 antimicrobial agents was tested by an agar dilution method. Antimicrobial agents with low MIC ranges, in micrograms/ml, were: meropenem Y or = 0.25, dirithromycin < or = 0.5, gentamicin > or = 1, amikacin, ofloxacin, tetracycline and erythromycin < or = 2. The MIC range of cefepime was 0.5-8 micrograms/ml, but those of other beta-lactams were relatively high. All of the isolates were interpreted to be susceptible to cefepime, meropenem, amikacin, gentamicin, ofloxacin, tetracycline and dirithromycin. A significant proportion of the isolates were either intermediate or resistant to ampicillin, cephalothin, cefotaxime, aztreonam, loracarbef and erythromycin. In conclusion, the organism remains susceptible to aminoglycosides and tetracycline. Greater in vitro activity of meropenem, ofloxacin and dirithromycin require clinical evaluation.
