Objective To investigate the significance of Human papilloma virus(HPV)typing in the screening of cervical dis-ease.Methods 687 cases of gynecological patients in the hospital were enrolled in the study,whose HPV-DNA genotype was detec-ted by real-time fluorescence quantitative PCR(FQ-PCR).In addition to that,389 healthy women who took gynecological examina-tion in the hospital in the same period were enrolled in the study,HPV-DNA quantitative detection were performed on those people (FQ-PCR were used)firstly,and the persons with more than 5×102 IU/mL HPV-DNA were tested for the HPV-DNA subtype. Results In the 687 cases of gynecological patients,164 cases were HPV positive which accounted for 23.9%;The single-infection patients accounted for 74.3%,mixed infection accounted for 25.6%.The mixed infection included 2 -4 types of infection,among which the double infection was most common.The common type were HPV16,52,58 and 35.In 389 cases of healthy women,29 ca-ses were found HPV positive,which accounted for 7.5%;The single infection accounted for 79.3%,mixed infection accounted for 20.7%,mixed infection included 2-3 types of HPV infection,in which double infection is the most common situation.The common type were HPV52,58,16 and 18.Conclusion HPV infection is the major cause of cervical cancer,HPV detection and typing con-tribute to cervical cancer screening and its prevention.

Objective To evaluate the protective effects of different modes of ventilation on the lungs on the operated side during one-lung ventilation (OLV ) in patients undergoing thoracic surgery .Methods Forty-five ASA physical status Ⅰ or Ⅱ patients of both sexes ,aged 45-64 yr ,weighing 65-80 kg ,were randomly divided into 3 groups (n=15 each) using a random number table :group A ,group B and group C .After induction of anesthesia ,the patients were intubated with double-lumen tube and OLV was performed .During OLV ,the lung on the operated side was collapsed naturally in group A ,positive pressure ventilation (FGF 2 L/min) was applied in the lung on the operated side in group B ,and high-frequency jet ventilation (frequency 100 beats/min ,driving pressure 0.5 kg/cm2 ) was used in the lung on the operated side in group C .Immediately after intubation (T0 ) , and at 1.5 h (T1 ) and 2 h (T2 ) of OLV ,blood samples were taken from the central vein and radial artery for determination of the serum interleukin-6 (IL-6 ) and IL-8 concentrations .The net release of IL-6 and IL-8 was calculated .Blood samples were taken from the radial artery at T0-2 for blood gas analysis and for determination of surfactant protein A (SP-A) concentration in the serum .Respiratory index (RI) was calculated .The non-cancer tissues 1.0 cm × 1.0 cm × 1.0 cm which were extracted from the lung cancer specimens were used for microscopic examination of the pathological changes of lungs which were scored .Results Compared with group A ,the net release of IL-6 and IL-8 ,serum SP-A concentration ,RI and pathological scores were significantly decreased at T1 ,2 in B and C groups ( P<0.05) .Compared with group B ,the serum SP-A concentration and RI were significantly decreased at T1 ,2 , and the net release of IL-6 was increased at T2 in group C ( P< 0.05 ) .Conclusion Continuous positive ventilation and high-frequency jet ventilation both can effectively protect the lungs on the operated side during OLV in patients undergoing thoracic surgery ,and the efficacy of high-frequency jet ventilation is better .

Objective To determine the influence of depression on C reactive protein in patients with chronic ischemic heart failure (CIHF).Methods 73 patients with CIHF were divided into CIHF without depression group(n=49) and CIHF with depression group (n=24) according to the standard sore of the self-rating depression scale.C reactive protein(CRP)and other clinical characteristics were detected.The geometric means of CRP between two groups were compared,and stepwise multiple linear regression analysis was used to confirm the independent correlation factors of CRP.Results (1) The geometric means of CRP in CIHF without depression group and CIHF with depression group were (1.38± 1.29)mg/L and (1.78±1.53) mg/L respectively.No statistically significant difference was found between two groups(P=0.276).(2) Stepwise multiple linear regression analysis showed that aspirin inversely related with CRP(β=-1.070,P=0.004),but brain natriuretic peptide (BNP)positively related with CRP(β=0.426,P=0.001).Conclusion Depression has no additional effect on CRP in patients with CIHF.

Objective To compare the postoperative analgesic effect of the single dose of oxycodone and dezocine in patients who underwent gynecological laparoscopic operation. Methods Sixty patients who underwent elective gynecological laparoscopic operation were randomly divided into two groups (n=30): oxycodone group (group O) and dezocine group (group D). Fifteen minutes before the end of surgery, oxycodone 0.1 mg/kg was given in O group, and dezocine 5 mg was given to D group. Twenty minutes before the end of surgery, tropisetron 5 mg was given to both groups. Analgesia was maintained by propofol-remifentanil with TCI. The mean arterial pressure (MAP) and heart rate (HR) of T1, T2, T3 and T4 were recorded respectively in both two groups. After the operation, pain of visual analogue scale (VAS) was assessed in 2 h ,4 h , 6 h and 24 h, respectively. Results There were no significant differences in MAP and HR between two groups at T1, T2, T3 and T4 (P＞0.05). The VAS score was significantly lower in group O than that of group D (P＜0.05). There was significant difference in the incidence of nausea between the two groups (P＜0.05). Conclusion Single dose of oxycodone 0.1 mg/kg can be used for postoperative analgesia after gynecological laparoscopic operation, and which has better analgesia than that of dezocine, except for the adverse reaction of nausea.

Objective To evaluate the correlation between stroke volume variation (SVV) and blood volume during one-lung ventilation (OLV).Methods Forty ASA Ⅱ male patients,aged 50-60 yr,with body mass index 20-25 kg/m2,scheduled for elective resection of esophageal cancer,were studied.Anesthesia was induced with fentanyl 4 μg/kg,propofol 2 mg/kg,and rocuronium 0.6 mg/kg.Double-lumen tube was inserted.Correct position was verified by fiberoptic bronchoscopy.The patients were mechanically ventilated (VT 8 ml/kg,RR 15 bpm,Ⅰ ∶ E 1 ∶ 2).6％ hydroxyethyl statch (HES) 130/0.4 was infused intravenously at a rate of 0.67 ml· kg-1 · min-1 starting from 30 min of OLV.SVV,cardiac output (CO),SV and cardiac index (CI) were monitored and recorded using the FloTrac/Vigileo (Edwards Lifesciences,USA) system before HES was infused and when the dose of HES reached 2,4,6,8,10 and 12 ml/kg.Spearman rank sum correlation coefficient was used to analyze the data.Results SVV was negatively correlated with the blood volume during OLV and the correlation coefficient was rSVV =-0.249.CI,CO and SV were positively correlated with the blood volume during OLV and the correlation coefficients were rCO =0.570,rSV =0.552 and rCI =0.550,respectively.Conclusion SVV is poorly correlated with the blood volume during OLV and can not reflect the blood volume accurately.

Objective To evaluate the correlation between stroke volume variation (SVV) and the blood volume. Methods Forty-eight ASA Ⅱ male patients, aged 50-60 yr, scheduled for elective radical operation for gastric cancer, were studied. Anesthesia was induced with fentanyl 4 μg/kg, propofol 2 mg/kg and cis-atracurium 0.15 mg/kg and maintained with inhalation of 2%-3% sevoflurane. 6% HES 130/0.4 was infused intravenously at a rate of 0.67 ml· kg - 1 · min - 1 30 min after induction. SVV,cardiac output (CO),SV and cardiac index (CI) were monitored and recorded using the FloTrac/Vigileo (Edwards Lifesciences, USA) system before HES was infused and when the dose of HES reached 2, 4, 6, 8, 10, 12, 14, 16 and 18 ml/kg. CVP was also recorded at the corresponding time points. Spearman's rank sum correlation coefficient was used to analyze the data. Results Correlation coefficients between the amount of HES infused and CO, SV, CI or CVP were rSVV = - 0.91 ± 0.06,rCO = 0.83 ± 0.04, rSV = 0.86 ± 0.09, rCI = 0.86 ± 0.09 and rCVP = 0.90 ± 0.03. Among the 5 correlation coefficients, rSVV was the highest, rCVP was significantly higher than rCO, rSV and rCI (P ＜ 0.05), and there was no significant difference among rCO, rSV and r CI (P ＞ 0. 05). Conclusion SVV is highly correlated with the blood volume and can be used to guide volume therapy.

Althoughtheevidenceoftheevidence-basedmedicinehasshowedthatrecombinant tissue-type plasminogen activator can effectively open the occluded vessels, because of its short therapeutic time w indow and the risk of bleeding, the thrombolytic rate is general y low er currently. Clinical studies have show ed that telestroke can effectively shorten the treatment time of the patients, increase the thrombolytic rate, reduce the risk of bleeding, and improve the outcomes of patients. Although the application of telestroke is restricted in many w ays, such as technology, policy, and funding, w ith the grow ing maturity of the related technologies, telestroke w il play an increasingly important role in the treatment of stroke.

Objective To explore the gender difference in clinical features and outcomes of elderly patients with coronary true bifurcation lesions after percutaneous coronary intervention (PCI).Methods A total of 169 consecutive patients were included in the study, who were diagnosed coronary true bifurcation lesions by coronary angiography (CAG)and received PCI in our hospital from December 2013 to December 2015.All patients were divided into 2 groups according to their gender (71 femals and 98 males).Angiographic characteristics of the coronary lesions and clinical data were analyzed in both groups.Clinical outcomes during follow up were recorded and studied.Results The levels of total cholesterol (TC), triglyceride (TG),high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) in the female group were significantly higher than in the male group (all P<0.05).The levels of BUN,Cr,UA,CyC and TBIL in the female group were significantly lower than in the male group (all P<0.05).Comorbidity rates of hypertension and diabetes were higher in female patients without significant differences (P>0.05).The median follow-up time was 17 months and the incidence rate of overall adverse events in women was higher than that of men (25.4% vs.11.2%, P<0.05).Conclusions The clinical outcomes of elderly patients with coronary true bifurcation lesions after PCI had gender differences.The rates of adverse events in female patients was found significantly higher than male patients.

Objective To investigate the optimum ratio of medicine dosage for dexmedetomidine mixed with oxycodone used for patient-controlled intravenous analgesia (PCIA) after gastrointestinal surgery.Methods Eighty patients of both sexes, aged 35-64 yr, weighing 55-75 kg, of American Society of Anesthesiologists physical status Ⅰ or Ⅱ , undergoing elective gastrointestinal surgery, were randomly divided into 4 groups (n=20 each) using a random number table: oxycodone group (group O), and different ratios of medicine dosage when dexmedetomidine was added to sufentanil groups (OD1-3 groups).At 15 min before the end of surgery, oxycodone 0.1 mg/kg was injected intravenously, and PCIA pump was connected simultaneously.In group O, the PCIA solution contained oxycodone 1.00 mg/kg in 100 ml of normal saline.In group OD1, the PCIA solution contained oxycodone 1.00 mg/kg and dexmedetomidine 2.5 μg/kg in 100 ml of normal saline.In group OD2 , the PCIA solution contained oxycodone 0.75 mg/kg and dexmedetomidine 2.5 μg/kg in 100 ml of normal saline.In group OD3, the PCIA solution contained oxycodone 0.50 mg/kg and dexmedetomidine 2.5 μg/kg in 100 ml of normal saline.The PCIA pump was set up to deliver a 0.5 ml bolus dose with a 15-min lockout interval and background infusion at 2 ml/h.Oxycodone 0.05 mg/kg was injected intravenously as a rescue analgesic, and visual analogue scale score was maintained ≤ 4.The requirement for rescue analgesics was recorded.The requirement for the rescue analgesic was recorded within 48 h after surgery.The number of successfully delivered doses, and occurrence of adverse reactions such as bradyeardia, hypotension, nausea, vomiting, over-sedation, somnolence, pruritus, and respiratory depression were recorded.Patient's satisfaction with analgesia was recorded at 72 h after surgery.Results No patients required the rescue analgesic or developed over-sedation, vomiting, respiratory depression and hypotension in the four groups.Compared with group O, the incidence of somnolence was significantly increased in group OD1, the incidence of nausea, somnolence, bradycardia and pruritus was decreased in OD2 and OD3 groups, and the degree of patient's satisfaction with analgesia was increased in OD1-3 groups (P＜0.05).Compared with group OD1, the incidence of nausea, somnolence, bradycardia and pruritus was significantly decreased in OD2 and OD3 groups, the degree of patient's satisfaction with analgesia was increased in group OD3 (P＜0.05) , and no significant was found in the degree of patient's satisfaction with analgesia in group OD2 (P＞0.05).Compared with group OD2, no significant was found in the incidence of adverse reactions (P＞0.05) , and the degree of patient's satisfaction with analgesia was significantly decreased in group OD3 (P＜0.05).The number of successfully delivered doses was significantly larger in group OD3 than in O, OD1 and OD2 groups (P＜0.05).Conclusion Dexmedetomidine 2.5 μg/kg added to oxycodone 0.75 mg/kg is the optimum ratio of medicine dosage when used for PCIA after gastrointestinal surgery.

Objective To investigate the effect and underlying mechanism of radioactive 125I seed implantation on the angiogenesis of transplanted human lung adenocarcinoma in nude mice.Methods An animal model of transplantd human lung adenocarcinoma was established by subcutaneous implanting A549 cells into nude mice.Twenty four tumor-bearing nude mice were randomly divided into 4 groups with different irradiation doses of blank control (without any treatment) and 0 MBq,22.2 MBq,29.6 MBq and by embedding radioactive 125I seeds with an 18 G implant needle.Tumor volumes were measured every 4 days until all mice were terminated 30 d later and the tumor growth curve was drawn.The microvessel density (MVD) in the tumor tissue was detected by immunohistochemistry S-P assay.The mRNA and protein levels of VEGF and HIF-1α of each group were detected by RT-PCR and Western blot,respectively.Results After embedding of 125I seeds,the tumor volumes of 22.2 MBq group (886 ± 97) and 29.6 MBq group (590 ± 107) were significantly smaller than those of control group (2 297 ± 149) at 54 d after administration (q =14.117,17.075,P ＜ 0.05),but there were no significant differences among 0 MBq group and control group,22.2 MBq and 29.6 MBq groups (P ＞ 0.05).The immunohistochemical CD34-positive staining demonstrated that MVD in 22.2 MBq group (522 ± 119) and 29.6 MBq group (491 ± 121) were decreased significantly compared with control group (922 ± 260) (q =4.826,5.197,P ＜0.05),but there were no significant differences among 0 MBq and control groups,22.2 MBq and 29.6 MBq groups(P ＞0.05).The mRNA expressions of VEGF and HIF-1α in 22.2 MBq group (0.279±0.0659,0.370 ±0.0857) and 29.6 MBq group (0.215 ±0.0620,0.278 ±0.0651) were significantly lower than those in the control group (q VEGFmRNA =18.881,17.211,q HIF-1αmRNA =15.376,14.733,P ＜0.05),but there were no significant differences among 0 MBq and control groups,22.2 MBq and 29.6 MBq groups(P ＞0.05).At the same time,the expression levels of VEGF and HIF-1α protein after 125I seed implantation were also obviously decreased in 22.2 MBq and 29.6 MBq groups (qvEGr =5.848,6.263,q HIF-1α =6.560,7.576,P ＜ 0.05),and no significant difference between 0 MBq and control groups(P ＞ 0.05) and between 22.2 MBq and 29.6 MBq groups (P ＞ 0.05).Conclusions Interstitial implantation with 125I seeds may potently inhibit angiogenesis in human lung adenocarcinoma xenografts of nude mice.
