Objective To investigate human papilloma virus(HPV) infection in normal endometrium, atypi-cal hyperplasia of endometrium and endometrial carcinoma. Methods By the nucleic acid hybridization,we detected 28 pairs of endometrial carcinomas, 21 pairs of atypical hyperplasia of endometrium. Normal endometrium from 16 pa-tients with uterine myomas were as control. Results HPV16/18 DNA was detected in 25 endometrial carcinoma and 2 atypical hyperplasia of endometrium and 1 normal endometrium. Conclusions Endometrial carcinoma HPV16/18 DNA were significantly higher than those infected with atypical endometrial hyperplasia and normal endometrium. Note the occurrence of endometrial cancer,the development may be associated with HPV infection.

Objective To determine the median effective target plasma concentration (EC50) of propofol inhibiting the response to laryngeal mask airway (LMA) insertion when combined with dexmedetomidine.Methods ASA Ⅰ or Ⅱ patients of both sexes,aged 20-60 yr,with body mass index 20-25 kg/m2,scheduled for surgeries under general anesthesia,were studied.EC50 of propofol was determined by modified Dixon' s up-and-down sequential experiment.After dexmedetomidine 1.0 μg/kg was infused over 10 min,propofol was infused by targetcontrolled infusion.The initial target plasma concentration of propofol was set at 3.0 μg/ml.LMA was inserted when the target effect-site concentration of propofol and target plasma concentration of propofol reached the balance and BIS value was 50-60.Each time the target concentration increased/decreased by 0.2 μg/ml according to the occurrence of the response to LMA insertion.The response to LMA insertion was defined as the occurrence of coughing,body movement,laryngospasm or systemic voluntary movement.EC50 and 95 ％ confidence interval (CI)of propofol for inhibition of the response to LMA insertion were calculated.Results The EC50 of propofol required for inhibition of the response to LMA insertion was 2.351 (95％ Cl 1.737-2.600) μg/ml when combined with dexmedetomidine 1.0 μg/kg.Conclusion The EC50 of propofol inhibiting the response to LMA insertion is 2.351 μg/ml when combined with dexmedetomidine.

The purpose of this study is to evaluate the embryotoxicity of alkaloids in Senecionis Scandentis Hebra on in vitro cultured mouse embryos. Mouse whole embryo culture (WEC) was applied in this study. Post-implantation (8.5 d) mouse embryos were isolated from their mothers, and cultured in medium of immediately centrifuged serum (ICS) with different concentrations of seneciphylline (target concentrations were 100, 50, 25 and 12.5 μg x mL(-1)) or senkirkine (target concentrations were 50, 25 and 12.5 μg x mL(-1)) for 48 h. After culturing completed, the development and organic morphodifferentiation of the cultured embryos were evaluated microscopically. Treatment with seneciphylline and senkirkine had adverse effects on the development and organic morphodifferentiation of embryos. The effect also had clear dose-response. Alkaloidals in Senecionis Scandentis Hebra had embryotoxicity on cultured embryos, which indicated that pregnant people exposed to Senecionis Scandentis Hebra may get potential risk on fetus.

Reproductive toxicity research takes an important place in traditional Chinese medicine pre-clinical safety evaluation. Modern reproductive toxicity experiment includes drug-related miscarriage, fetal death, teratism, and adverse effects on fertility, genital system, embryonic development and fetus, which is different from contraindicated in pregnancy in traditional Chinese medicine theory. Now the three-phases reproductive toxicity study is the method mainly applied in traditional Chinese medicine reproductive toxicity evaluation. Besides that, alternative methods of whole embryos culture and embryonic stem cell test are also used in traditional Chinese medicine embryo toxicity evaluation. This article reviews research progress and pre-clinical evaluation on reproductive toxicity of traditional Chinese medicine.

ObjectiveTo investigate the clinical promoting effect of crossing nape electroacupuncture on the recovery of swallowing function and recovery from pulmonary infection in post-cerebral infarction patients with tracheotomy.MethodSixty post-cerebral infarction patients with cough reflex disorder and swallowing dysfunction associated with pulmonary infection receiving tracheotomy and tracheal intubation were subjects. They were allocated, using a random number table, to three groups, 20 cases each. In each group, the patients were enrolled in order of visits. The three groups were given the same basic treatment for fighting inflammation, resolving phlegm and improving blood supply. The crossing nape electroacupuncture group received bilateral points Fengchi (GB20), Yifeng (TE17), Dicang (ST4)-to-Jiache (ST6) and Lianquan (CV23) acupuncture with electrodes connected by left-right crossing. The acupuncture group received bilateral points Fengchi, Yifeng, Dicang-to-Jiache and Lianquan acupuncture without electrodes connected. The control group received basic treatment with Western drugs without acupuncture therapy. Observations were carried out using the Kubota’s water drinking test, the Toshima Ichiro Swallowing Assessment and the Clinical Pulmonary Infection Score. The clinical therapeutic effects were evaluated in the three groups.ResultThe therapeutic effects evaluated using the Kubota’s water drinking test and the Toshima Ichiro Swallowing Assessment were better in the crossing nape electroacupuncture group than in the acupuncture group and better in the acupuncture group than in the control group (P<0.05). The score of the Clinical Pulmonary Infection Score decreased in all the three groups. The promoting effect on recovery from pulmonary infection was marked in the crossing nape electroacupuncture group (P<0.01).ConclusionCrossing nape electroacupuncture has a marked improving effect on dysphagia in post-cerebral infarction patients with tracheotomy and tracheal intubation. It can promote recovery from pulmonary infection in post-cerebral infarction patients with cough reflex disorder receiving tracheotomy and tracheal intubation.

Objective The aim of the study was to explore the influencing factors of exercise tolerance in patients with myocardial infarction (MI) after percutaneous coronary intervention (PCI) revascularization in acute state. Methods A total of 112 patients with first MI undergoing PCI revascularization in acute state and completing cardiopulmonary exercise testing (CPET) were enrolled. Exercise capacity was evaluated by peak oxygen consumption percentage (VO2 peak%) in CPET. Patients were divided into normal exercise capacity (NEC) group (n=40) and abnormal (AEC) group (n=72) according to VO2 peak% value. Clinical manifestations, histories of hypertension and diabetes, medications, coronary arterial angiography and echocardiography findings of patients were compared. The onsets of diabetes and blood glucose levels during the period of CPET were evaluated in the MI patients with diabetes. The patients were followed up for major adverse cardiovascular events (MACE) (admission due to chest pain, re?revascularization, re?infarction and all?cause death) within 24 months after PCI. Multivariate logistic regression analyses were conducted to examine influencing factors for exercise tolerance. Results The ratio of diabetes, type C lesions in the AEC group were higher than those in the NEC group (diabetes: 37.5% vs. 17.5%; type C lesions: 69.4% vs. 42.5%, respectively, all P<0.05). The left ventricular ejection fraction (LVEF) in patients in the AEC group was lower than that in the NEC group [(60.6±10.0) % vs. (65.0±8.2) %, P=0.019]. Multivariate logistic regression analyses showed that history of diabetes and history of type C lesions were the independent risk factors for the declined exercise capacity in the MI patients after PCI revascularization ( OR=3.14, 95%CI 1.167-8.362, P=0.023; OR=3.32, 95%CI 1.444-7.621, P<0.01). Among the MI patients with diabetes, the duration of diabetes in the AEC group was significantly longer than that in the NEC group[ (7.7 ± 3.6)years vs. (5.0 ± 2.4)years] and the proportions of subjects reaching target levels of fasting plasma glucose (40.7% vs. 57.1%) and glycosylated hemoglobin A1c(HbA1c) (55.6% vs. 71.4%) in this group were significantly lower than those in the NEC group (all P<0.05). A multivariate logistic regression analysis showed that reaching HbA1c target was an independent predictor of improved exercise tolerance in MI patients with diabetes who received PCI ( OR=2.518, 95%CI 1.395-7.022, P=0.021). No significant differences were observed in incidence of admission due to chest pain, re?revascularization and re?infarction between the two groups within 24 months after PCI between the groups. Conclusions Diabetes and type C lesions are independent risk factors of declined exercise capacity in patients with first myocardial infarction who received revascularization in acute state. Reaching target HbA1c is independent factor of improved exercise capacity in patients with myocardial infarction and diabetes.

Reaching target HbA1c is independent factor of improved exercise capacity in patients with myocardial infarction and diabetes.

Objective To investigate the influence factors of Cornell product and its clinical value in pa-tients with left ventricular high voltage.Methods 104 patients with left ventricular high voltage were studied and divided into two groups according to Cornell product:Cornell product normal group(n = 78)and Cornell product abnormal group(n=26). Clinical manifestations ,complicaions and ultracardiographic data in these patients were collected and analyzed. Results Chronic kidney disease(CKD)(OR=4.266,95%CI 1.276-14.257,P=0.018) and left ventricular mass index(LVMI)(OR = 1.023,95%CI 1.004-1.043,P = 0.016)were related to Cornell product. Cornell product was positively correlated LVMI appeared(r=0.497,P<0.001). The correlation of Cor-nell product with left ventricularend-diastolic dimension ,interventricular septal thickness and left ventricular poste-rior wall thickness was weak.ROC-AUC of Cornell product for CKD was 0.634,95%CI=0.506-0.780,P=0.039, sensibility 47.8%,and specificity 81.5%. Conclusions LVMI and CKD are independent influence factors of Cor-nell product. Cornell product has a certain diagnositc value for left ventricular hypertrophy ,but it has no associa-tion with the location of ventricular hypertrophy.
