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 evaluate the effects of different doses of dexmedetomidine on stress responses of the hypertensive patients undergoing thoracic surgery and find the uptimal infusion rate of dexmedetomidine in decreasing stress responses.Methods Sixty hypertensive patients of both sexes,aged 45-64 yr,weighing 65-80 kg,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,were divided into 4 groups (n =15 each) using a random number table:control group (group C) and 3 different doses of dexmedetomidine groups (D1-3 groups).In D1,D2 and D3 groups,dexmedetomidine 0.2,0.3 and 0.4 μg · kg 1 · h 1 were intravenously infused until 30 min before the end of surgery,respectively,starting from 15 min before induction of anesthesia.The equal volume of normal saline was given instead of dexmedetomidine in group C.Before administration of dexmedetomidine (T0),at 1 min after endotracheal intubation (T1),at skin incision (T2) and immediately after extubation (T3),venous blood samples were collected for determination of epinephrine and norepinephrine concentrations in plasma (using high-performance liquid chronatography) and blood glucose concentrations.The development of adverse effects such as bradycardia,hypotension and respiratory depression was recorded.Results Compared with group C,epinephrine and norepinephrine concentrations in plasma and blood glucose concentrations were significantly decreased at T1-3 in D1,D2 and D3 groups,the incidence of bradycardia and hypotension was significantly increased in group D3 (P＜0.05),and no significant change was found in the incidence of bradycardia or hypotension in D1 and D2 groups (P＞0.05).There were no significant differences in epinephrine and norepinephrine and concentrations in plasma and blood glucose concentrations at each time point between group D1,group D2 and group D3 (P ＞ 0.05).Conclusion The optimal infusion rates of dexmedetoinidine are 0.2 and 0.3μg · kg-1 · h-1 in decreasing stress responses of the hypertensive patients undergoing thoracic surgery.

Objective To determine the optimal dose of oxycodone for patient-controlled intravenous analgesia (PCIA) after gastrointestinal surgery when combined with dexmedetomidine in elderly patients.Methods Sixty patients of both sexes,aged 65-80 yr,weighing 50-75 kg,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ,undergoing elective open gastrointestinal surgery,were divided into 3 different doses of oxycodone groups (group O1,group O2 and group O3,n=20 each) using a random number table.At 15 min before the end of surgery,oxycodone 0.1 mg/kg was intravenously injected,and PCIA pump was connected simultaneously.In O1,O2 and O3 groups,the PCIA solution contained dexmedetomidine 2.0 μg/kg and oxycodone 0.3,0.5 and 0.7 mg/kg in 100 ml of 0.9％ normal saline,respectively.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 intravenously injected as a rescue analgesic after surgery,postoperative pain was assessed using a verbal rating scale,and the verbal rating scale score was maintained ≤4.The number of successfully delivered doses and requirement for rescue analgesics were recorded within 48 h after surgery,and the rate of rescue analgesia was calculated.The occurrence of adverse reactions such as nausea,vomiting,dizziness,respiratory depression,somnolence,bradycardia,hypotension and over-sedation was recorded.Patients' satisfaction with analgesia at postoperative 72 h and the length of postoperative hospital stay were also recorded.Results Compared with group O1,the rate of rescue analgesia after surgery and the number of successfully delivered doses were significantly decreased,and the degree of patients' satisfaction with analgesia was increased in O2 and O3 groups,and the incidence of nausea and somnolence was significantly increased in group O3 (P＜0.05).Compared with group O2,no significant change was found in the rate of rescue analgesia after surgery or the number of successfully delivered doses (P＞0.05),and the incidence of nausea and somnolence was increased in group O3 (P＜0.05).Conclusion When combined with dexmedetomidine 2.0 μg/kg,the optimal dose of oxycodone for PCIA is 0.5 mg/kg after gastrointestinal surgery in elderly patients.
