Objective To understand the epidemic situation of common human soil-transmitted nematode infections in Quan-zhou City in 2012,so as to provide the evidence for improving the prevention and control measures. Methods The residents aged above 3 years from 5 townships in 2 counties were investigated to detect the parasite eggs(hookworm,Ascaris lumbricoides,Trich-uris trichura)by Kato-Katz technique. One kindergarten of each county was randomly selected and 228 children were investigated to detect Enterubius vermicularis eggs by the cellophane tape anus test. Results The total hookworm infection rate was 3.60%(69/1919). For the hookworm infection rates,there was no significant difference among different areas and between different genders, but there were significant differences among different age groups and different careers. No Enterubius vermicularis eggs were detect-ed. Conclusion The effect of the prevention and control of Ascaris lumbricoides,Trichuris trichura and Enterubius vermicularis in-fections is remarkable. However,the infection rate of hookworm has a rising trend and the prevention and control of hookworm in-fection should be strengthened.

Objective To summarize perioperative points for nursing patients with extramammary Paget’s disease undergoing resection of tumor of vulva expansion and flap repair.Method Eleven patients with extramammary Paget’s disease were managed with resection of tumor of vulva expansion and flap repair,and with perioperative care as well.Results The tumors in all of the patients were removed completely and the flaps survived.All patients were discharged for hospitalization of(4.5±0.7)days.No flap infection or necrosis occurred.Conclusion The measures for nursing the patients with extramammary Paget’s disease undergoing resection of tumor of vulva expansion and flap repair may include preoperative preparation,mental care,postoperative observation of flaps, prevention of complications,health education,instruction on nutrition and formation of proper life style,which may be beneficial for the smooth manipulation of resection as well as for the postoperative rehabilitation.

Objective To study the effects of prolonged oxygen exposure at different concentrations on expressions of vascular endothelial growth factor (VEGF) and its receptors (VEGF receptor-1 ,VEGFR1 and VEGF receptor-2, VEGFR2)mRNA in lungs of neonatal rat. Methods Thirty-two SD rat pups were randomly divided into control and experimental group. Rats in the experimental group were further divided into three subgroups: 30% O2, 50% O2 and 75% O2 group. Each group had 8 rats. The rats were ,sacrificed at postnatal day 21 and their right lower lobes were collected. Expressions of VEGF, VEGFR1 and VEGFR2 mRNA were detected by RT-PCR. Results There was no effect on VEGF, VEGFR1 or VEGFR2 mRNA expression in 30% O2 group. The expressions of VEGF mRNA in the 75% O2 group was 0. 48 times of the control (P<0. 05). The expressions of VEGFR1 mRNA(P<0.01) and VEGFR2 mRNA (P<0.01) in 50% O2 and 75% O2 group were lower than those of control. Condusions Prolonged exposure to moderate or high oxygen concentration may reduce the expression of VEGF and its receptors' mRNA in the lung tissues of neonatal rats.

One of the focuses in bone and cartilage tissue engineering research is to find suitable seed cells. Embryonic stem cells derived from the inner cell mass of blastocysts possess unique characteristics such as unlimit- ed capacity of proliferation and the potential to differentiate into diverse cell types (pluripotentiality), which make them a promising cell source for tissue engineering. In this paper, the progress in the study on embryonic stem cell differentiating directly into osteoblasts and chondrocytes is introduced. The prospects and difficulties of using em- bryonic stem cells as seed cells for tissue engineering are also discussed.

Objective To study the histopathologieal features,growth pattern and distribution on the uterine cervix of high-grade cervical intraepithelial neoplasia(CIN).Methods Cone biopsy and hysterectomy specimens of 592 women with hish.grade CIN(CIN Ⅱ or Ⅲ)were reviewed morphologically.Of all cases.the gross appearance of the external os was recorded,and the frequency of eervical quadrants involved in hish-grade CIN was assessed.Two hundred specimens were selected randomly to observe micrographieal changes,including the extent,depth,growth pattern and cell types of hish-grade CIN and the alteration of stroma surrounding CIN.Results Of 592 specimens,external os showed smoothness in 46 cases(7.8%),mild erosion in 151 cases(25.5%),moderate or severe erosion in 395 cases(66.7%),hypertrophy in 48 cases(8.1%),and neoplasm in 4 cases(0.7%).Higll-grade CIN involvement was equally frequent on each quadrant of cervix(P>0.05).Of 200 cases of hish-grade CIN reviewed micrographically,the depth of the deepest involred crypt was le88 than 3 mm in 188 specimens (94.O%).between 3 to 5 nnn in 12 specimens(6.O%),and more than 5 mm in none.High-grade CIN with isolated endocervieal crypt involvement was detected in 77 cases(38.5%),multiple crypt involvement in 143 cases(71.5%).and confluent crypt involvement in 73 cases(36.5%).Hish-grade CIN showed explanate in 81.0%(162/200)of cases,endophytie in 49.0%(98/200)of cages,and exophytic in 6.5%(13/200)of cases.Abrupt transition between CIN and normal epithelia were found in 167 specimens (83.5%),whereas gradual transition in 66 specimens(33.0%).A variety of cell types,but basaloid type predominantly.were observed in hiSh-grade CIN.In 28.5%-45.0%of ca8es,the stroma surroundin CIN displayed oedema,desmoplastic and lymphocytic responses.Conclusions Our data suggest that gross examination is of little importance for diagnoses of CIN.CIN trend to spread horizontally and Mong the endocervical crypts,and are mainly distributed to a depth less than 3 nLrn.These data also suggest that there are a variety of cell types of CIN,and stroma responses to CIN may exist in part of high-grade CIN.

OBJECTIVE:To analyze the influential factors for blood concentration of vancomycin in neonates,and to provide reference for clinical medication. METHODS:In retrospective study,114 cases of blood concentration monitoring of vancomycin were collected from neonatal department of our hospital during Jul. 1st 2014 to Jun. 30th 2015,and general information were record-ed;the influential factors for blood concentration of vancomycin were analyzed by multiple factors linear regression analysis. RE-SULTS:The blood concentrations of vancomycin in 114 neonates were 2-39 μg/ml,and average blood concentration was(13.24± 8.66)μg/ml. The blood concentrations of 43 cases were within effective range(10-20 μg/ml),accounting for 37.72%. Premature (r=0.264) and serum creatinine level (r=0.289) of neonates were positively correlated with blood concentration (P<0.05), while birth weight(r=-0.264)and body weight on monitoring day(r=-0.236)were negatively correlated with blood concentra-tion (P<0.05). The serum creatinine level (r=0.304) of prematures was positively correlated with blood concentration (P<0.05),and gestational age(r=-0.373),correct gestational age(r=-0.431)and body weight on monitoring day(r=-0.263) were negatively correlated with blood concentration(P<0.05). CONCLUSIONS:Premature,body weight,gestational age,serum creatinine level and other factors all influence the blood concentration of vancomycin. The influential factors should be considered when using vancomycin. Treatment plan should be adjusted according to the results of blood concentration and clinical symptom.

Objective To investigate the correlation between indexes of thrombelastogram (TEG) and hemorrhagic transformation (HT) after acute ischemic stroke.Methods The cases of acute ischemic stroke but not receiving early reperfusion therapy were recruited in our hospital from January to November 2016,and were divided into HT group and non-HT group.Their general clinical characteristics and TEG indexes were retrospectively analyzed,and comparison between two groups and multivariate Logistic regression analysis were performed.Results A total of 71 cases were enrolled and 11 of them were divided into HT group.The percentages of massive cerebral infarction and cardio-embolic stroke were significantly higher in HT group than those in non-HT group (P<0.05),whereas the levels of CI in HT group were significantly lower than thoes in non-HT group(P<0.05).Multivariate Logistic regression analysis showed that massive cerebral infarction (OR=13.172,95%CI:1.414-122.671) and CI(OR=0.554,95%CI:0.321-0.956) were independently correlated with HT(P<0.05).Conclusion CI is independently correlated with HT after acute ischemic stroke,and may be a potential predictor of HT.
