The Journal of Practical Medicine 2014;(13):2074-2077
Objective To study the expression of CXCL12 and E-cadherin in condyloma acuminatum (CA) lesions caused by low-risk type (HPV6 and HPV11) humanpapilloma viruses. Methods The expressions of CXCL12 and E-cadherin mRNA in the lesions of CA caused by HPV6 and HPV11 and in the foreskins from normal males as controls were detected by real-time fluorescent quantitative PCR. Results The expressions of CXCL12 in the lesions of CA were down-regulated (fold change = 20.23,P = 0.001), and the expressions of E-cadherin were up-regulated (fold change = 3.129,P > 0.05). Conclusions The expression of CXCL12 is lower and the expression of E-cadherin is higher in the lesions of CA caused by low-risk HPV. It suggests that HPV may suppress local immune response and change the adhesion between langerhans cells and keratinocytes , which may contribute greatly to the persistent infection of HPV and relapse of CA.

Microula Sikkimensis is a kind of plant only in China. Fatty acid composition of its seed oil was analyzed with a polar PEG-20M fused-silica capillary column GC combined with MS after the seed oil was saponified and methylated. 13 kinds of fatty acid methyl ester (FAMEs) were identified. The major constituents were found to be oleic acid 18.12%, linoleic acid 35.11%, ?-linolenic acid 8.33%, ?-linolenic acid 13.57% and stearidonic acid 1.21%.

Objective To study the psychological stress level of medical nurses when the hospitalized cancer patients died and to investigate the related factors.Methods Toally 72 medical nurses on duty who encountered cancer patient's death between May 2013 to November 2015 were enrolled in the study.SCL-90 was used to investigate the mental stress levels in the medical nurses on days 3 and 7 after the patient's death,which were compared with the norm.The correlations between psychological stress level and related factors were studied.Results The score by SCL-90 on day 3 was significantly higher than that on day 7 (147.15±29.09 vs.133.62±20.37,t=6.64,P=0.00).Compared to the norm,the scores on 9 dimensions of SCL-90 were significantly different 3 days after the patient's death;dimensions of SCL-90 were significantly different 7 days after parternt's death (P<0.05).Professional working was factor for medical nurse's acute stress disorder.Conclusion Cancer patients' deaths render huge impact on medical nurses,with acute stress disorder most manifest.In order to improve the the psychological quality of nurses,especially the young and inexperienced ones,we have to enhance the death education,helping them to seek for social support.

Objective To explore the influence of stereoscopic vision on the development of posterior capsule opacification (PCO) after intraocular lens implantation. The efficacy of Nd: YAG laser was studied. Design Case-controlled study. Participants 57 consecutive patients with POC(59 eyes with phacoemulsification and IOL implantation). Methods A prospective observational study was conducted comprising 57 patients (59 eyes) who had postoperative PCO. Neodymium: YAG (Nd: YAG) laser posterior capsulatomy was performed on all patients following a standardizes procedure. Preoperative and postoperative evaluation included LogMAR visual acuity, best-corrected visual acuity (BCVA), contrast sensitivity and stereoscopic vision. Main Outcome Measures LogMAR visual acuity, BCVA, contrast sensitivity and stereoscopic vision. Results The average LogMAR eyesight median of sick eye before laser treatment was (0.22?0.31) and the contrast sensitive degree of each frequency area was relatively lower than the opposite eye; After the treatment, there was evident improvement of the sick eye, and the LogMAR eyesight median of that was 0.00; The ratio of reaching the central spatial eyesight and the average sharpness degree both improve much than ahead of treatment. Those whose spatial eyesight sharpness don't get normal after the low best remedy eyesight. Irregular dipodic and previous eye disease. Conclusions LogMAR visual acuity, BCVA, contrast sensitivity and stereoscopic vision were damaged markedly with PCO. Our results indicate that Nd: YAG capsulotomy may affect the reconstruction of stereoscopic vision. Nd:YAG laser posterior capsulotomy is a valuable and clinically relevant method for clinical treatment of PCO.

Objective To explore the relationship between serum tumor markers and cervical cancer by using Logistic regression, and to further establish the diagnosis model of squamous cell carcinoma antigen (SCC) in cervical cancer by using chi-squared automatic interaction detector (CHAID) analysis of decision tree.Methods Total of 581 cases of cervical cancer,342 cases of cervical benign diseases and 341 cases of healthy controls who detected tumor markers in Taizhou Hospital of Zhejiang during 2010-2013, were retrospectively studied.The test results of carbohydrate antigen 199 (CA199), carbohydrate antigen 125 (CA125), carcinoembryonic antigen (CEA), SCC, and alpha fetoprotein (AFP) were reviewed.The Logistic regression were firstly used in screening the related tumor markers of cervical cancer, and then the CHAID method of decision tree was used in determining the values of the related tumor markers on the diagnosis of cervical cancer.The SCC elevated cases of uterine disease from January 2014 to December 2014 were collected to verify the diagnostic value of SCC in cervical cancer patients.Results Logistic regression analysis showed that among the 5 tumor markers which might be associated with cervical cancer, SCC was the only one which had statistical significance between cervical cancer and cervical benign diseases (Wald x2 =22.120,P =0.000), the OR and its 95% CI was 1.900 (1.454-2.483).With the SCC numerical increases, the proportion of patients with cervical cancer also gradually increased, when SCC > 2.20 μg/L, the positive predictive value was 94.7%.In 284 cases of SCC higher than 2.20 μg/L who considered as uterus related diseases, there were 270 cases (95.1%) who were eventually confirmed as cervical cancer.Conclusion There was a good diagnostic value of SCC for cervical cancer patients.

Objective Onto investigate the significance of the pleth variability index (PVI) in predicting hypotension after epidural anesthesia for cesarean delivery. Methods Sixity seven pregnant women, with ASAⅠ~Ⅱ, aged 19 ~ 34 years, were enrolled for elective cesarean delivery. SBP, BDP, MAP, HR, PI and PVI were measured at 5 min after the parturients arrived in the operation room. SBP, BDP, MAP and HR were measured every 3 min after epidural anesthesia. According to the change rate of SDP or MAP was higher than 30% or not, the parturients were divided into two groups (the hypotension group and the non-hypotension group). Results No significant differences were found in parturients'age, body height, weight, BMI, gestational weeks, SDP, DBP, MAP and HR before anesthesia between two groups. The PVI in the hypotension group was significantly higher than that in the non-hypotension group (P<0.05). A receiver operator characteristic curve analysis showed the area under curve was 0.888 when PVI was used for boundary value. When PVI over 17.35 was used as the occurrence of hypotension, the sensitivity of PVI was 0.727, and specificity was 0.895. Conclusion PVI can be used to predict the occurrence of hypotension after epidural anesthesia for cesarean delivery.
