Objective To compare the feasibility and efficacy between dexmedetomidine and midazolam in herniorrhaphy surgery for older patients. Methods Sixty American Society of Anesthesiology (ASA) gradeⅠ~Ⅱpatients, treated by herniorrhaphy surgery under local anesthesia,were randomly divided into dexmedetomidine group (n=30) and midazolam group (n=30) .Patients in dexmedetomidine group were given dexmedetomidine at a loading dose of 1μg/kg for 10 min,then they were injected continuously by 0.4μg/(kg·h),whereas midazolam group were given midazolam at a loading dose of 0.06 mg/kg, then 0.04 mg/(kg·h) injected continuously.The mean blood pressure (MAP) and heart rate (HR) were recorded before infusion (T0),incision of skin (T1),15min (T2) and 30 min (T3) after administration and when sutured skin (T4), adverse reaction were also assessed. Results The difference of sedation level was not significant between the two groups (P>0.05) .Compared with T0 , the decrease of HR was significantly more in dexmedetomidine group from T1 to T4 (P<0.05) . Compared with midazolam group , the decrease of HR was significantly more in dexmedetomidine group from T1 to T4 (P<0.05) . Compared with dexmedetomidine group, the rate of respiratory depression and restlessness were more in midazolam group, but bradycardia was lower (P<0.05) .Conclusions Dexmedetomidine is a comparable alternative to midazolam for sedation in herniorrhaphy surgery under local anesthesia. It is associated with better respiration and lower restlessness but with a high incidence of bradycardia.

Objective To observe the clinical effect of dexmedetomidine for preventing agitation during extubation period in the patients undergoing percutaneous nephrostolithotomy.Methods Sixty ASA Ⅰ-Ⅱ patients with elective percutaneous nephrostolithotomy under general anesthesia were selected and randomly assigned to the dexmedetomidine (DEM) and normal saline group (NS),30 cases in each group.The DEM group was given dexmedetomidine 0.5 μg/kg by intravenous pumping at 30 min before the end of the operation,while the NS group was given the equal volume of normal saline by intravenous pumping for 10 min.MAP and HR were recorded before anesthesia induction(T0),at the end of skin suturing(T1),at the moment of extubation(T2),at 5 min (T3) and 10 min(T4)after extubation.The eye opening time and extubation time,and incidence of agitation were observed in the two groups.Results MAP and HR at T2,T3 and T4 in the DEM group were lower than those in the NS group(P＜0.05).MAP and HR at T2,T3,T4 in the NS group were higher than those before anesthesia induction(P＜0.05).The total incidence rate of agitation during extubation period in the DEM group was also significantly lower that that in the NS group(P＜0.01).No statistically significant differences were found between the two groups in the recovery time and extubation time(P＞0.05).Conclusion Intravenous pumping of dexmedetomidine 0.5 μg/kg at 30 min before the end of percutaneous nephrostolithotomy can effectively reduce the occurrence of agitation during extubation period.

Objective To investigate awareness and influencing factors of human papilloma virus (HPV)self-sampling for cervical cancer screening of female in Shenzhen.Methods A total of 544 female,who during July 2014 to June 2015,participated in live and online HPV self-sampling detection organized by our hospital,were surveyed by self-designed questionnaire.Their epidemiological data,HPV and cervical cancer related knowledge,awareness of HPV self-sampling for cervical cancer screening,their attitude,willingness and acceptance to HPV self-sampling for cervical cancer screening were investigated.Effects of awareness of HPV self-sampling to the cervical cancer screening and main influencing factors were analyzed.Results Among the 544 women,47.1% were aware of HPV;22.8% were aware of what diseases could be caused by HPV;12.5%had heard of and done by themselves self-sampling for cervical cancer screening;only 6.3% had heard of and participated in online self-sampling for cervical cancer screening.Women,who were enterprise /corporate white collar/independent enterprise manager or whose monthly income was over 30,000 yuan,were less aware of HPV self-sampling than other women (χ2 =13.058,12.626;P <0.05).81.6% of the female were apparently inclined to be sampled by doctors,and only 7.0% of the female believed that credibility of self-sampling screening was above 80%.The biggest concern about online self-sampling was mainly metamorphic specimens during transport,pollution,etc.Conclusions Awareness of female in Shenzhen about HPV and HPV self-sampling cervical cancer screening are relatively low.Intervention should be emphasized in reliability degree of self-sampling result,discomfort degree of sampling,complexity,specimen preservation,transport and result feedback.

Objective To compare the effects of 4 different shaping angle tubes on the success rate of tracheal intubation and postoperative pharyngeal complications among anesthetic beginners.Methods 160 patients who underwent laparoscopic cholecystectomy under general anesthesia,with ASA classification Ⅰ to Ⅱ,no history of difficult airway,were randomly divided into 4 groups according to the catheter shape and tip shaping angle:35°banana-shaped elbow group(A Group),50°banana-shaped bent pipe group(Group B),35°straight pipe group(Group C),50°straight pipe group(Group D),with 40 cases in each group.After induction of general anesthesia,tracheal intubation is performed using a video laryngoscope.The Cormack-Lehane grade of laryngoscope exposure,external laryngeal compression,one-time success rate of intubation and intubation time were recorded.SPO2,HR and MAP were recorded before anesthesia induction(T0),at the end of anesthesia induction drug injection(T1),immediately after intubation(T2)and 1min after intubation(T3).The incidence of pharyngeal pain and hoarseness immediately after extubation and 24 hours after operation were followed up.Results There were no statistically significant differences in Cormack-Lehane classification,HR,and MAP among the four groups of patients at each time point(P>0.05).The number of cases requiring external laryngeal compression,intubation time,first-time intubation success rate,immediate postoperative sore throat,and immediate postoperative hoarseness rates in Groups B and D were all lower than those in Groups A and C,and the differences were statistically significant(P<0.05).Conclusion When using video laryngoscope for tracheal intubation,50°banana-shaped curved tube and 50°straight tube can shorten the intubation time,reduce postoperative complications,and have no obvious hemodynamic fluctuations.

Objective:To evaluate the clinical outcomes of internal fixation using double reverse traction reducers in the treatment of tibial plateau fractures.Methods:This study retrospectively examined the medical records of 48 patients who underwent surgical intervention for tibial plateau fractures at the Affiliated Hospital of Qingdao University between January 2021 and September 2022. The cohort, aged between 35 to 68 years (mean: 53.0±7.9 years), included 23 males and 25 females. Fractures were classified according to the Schatzker system, with 9 type III, 23 type IV, 11 type V, and 5 type VI fractures recorded. Patients were divided into two groups based on the surgical approach: the minimally invasive group underwent treatment with double reverse traction reducers for reduction and internal fixation in 24 cases, while the open group received conventional open reduction and internal fixation in 24 cases. Comparative parameters included operation duration, intraoperative blood loss, hospital stay, early postoperative knee mobility, and weight-bearing timelines. Postoperative radiographic images were appraised using the Rasmussen imaging score, and knee functionality was assessed at the final follow-up with the Hospital for Special Surgery (HSS) score and the International Knee Documentation Committee (IKDC) score.Results:The preoperative general data were statistically indifferent between groups ( P>0.05). All patients were followed for 13.5±4.3 months (range, 9.5-24 months). In the minimally invasive group, operative time was 88.96±19.04 minutes, intraoperative blood loss was 65±32 ml, and hospital stay was 11.8±3.9 days. Early postoperative knee joint activity commenced at 8.96±2.84 days, significantly earlier compared to the open group, which recorded 178.63±67.75 minutes of surgery, 114.16±65.05 ml blood loss, a 15.3±4.8 days hospital stay, and 16.83±4.09 days to knee joint movement. The difference was statistically significant ( P<0.05). No significant variation was observed in the time to bone healing between the minimally invasive group at 12.6±3.8 weeks and the open group at 13.21±4.98 weeks ( P>0.05). Rasmussen imaging criteria revealed 21 excellent and 3 good outcomes in the minimally invasive group, and 19 excellent and 5 good in the open group, with no statistical significance in the excellent-good rate differentiation ( P>0.05). Bone healing occurred within 3.2±0.8 months (range, 2.5-6.0 months), with 79% (19/24) in the minimally invasive group and 75% (18/24) in the open group achieving healing within 3 months. The open group had one incidence of superficial skin infection, and one patient in the minimally invasive group developed deep vein thrombosis (DVT); no other related complications were documented. Conclusion:Minimally invasive treatment of tibial plateau fractures using double reverse traction reducers offers significant benefits, including reduced surgical time, minimal blood loss, less soft tissue trauma, and enhanced joint function recovery. This approach is particularly advantageous in managing complex tibial plateau fractures compared to traditional open reduction and internal fixation methods.

Objective To evaluate the feasibility of the BioPerfectus multiplex real time (BMRT) HPV assay for self-sample cervical cancer screening. Methods Eight hundreds and thirty-nine self-collected and physician-obtained DNA samples from the Shenzhen cervical cancer screening trialⅣ(SHENCCAST-Ⅳ) study collected samples for cervical cancer screening during June 2013 to September 2014 were detected by BMRT HPV assay to evaluate the screening efficacy. Results A total of the 839 women who were screened, 804 with complete BMRT HPV data was included in the study, and average age was (46±7) years. Of the 804 women, the positive rates of 14 high-risk HPV genotypes (including HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 53, 56, 58, 59, 66 subtype) of self-sample and physician-obtained samples were 12.2% (98/804) and 12.8% (103/804), respectively (χ2=0.14, P=0.71). Self-collected samples with HPV-positive had significantly more cells (median 19 901.0) than physician-obtained samples (median 1 778.4), and there was statistically significant difference (Z=-7.61, P<0.01). The degree of agreement between self-sample and physician-obtained samples of HPV 16, HPV 18 and other 12 high risk HPV genotype was 99.8%, 100.0% and 96.1%, respectively. And the consistent Kappa value was 0.95,1.00 and 0.81, respectively. Of 804 samples, there were 6 cervical intraepithelial neoplasia (CIN)Ⅱ+cases. There were no missed CINⅡ+cases by BMRT HPV assay. Conclusion BMRT HPV assay is feasible for self-sample cervical cancer screening.
