Objective To compare the effects of five different target-controlled concentrations of propofol combined with finite concentration of remifentanil on intraoperative awareness,so as to determine the safer and more effective concentration of propofol which could decrease explicit memory and reduce the incidence of intraoperative awareness. Methods One hundred and fifty patients ( ASAⅠ-Ⅱ) were randomly divided into five groups. There was no significant difference between each group in general condition. Before awaking,the target controlled concentration of remifentanil was adjusted to 2. 4 μg·L-1 in all five groups. Groups R1,R2,R3,R4 and R5 also received 0. 9%normal saline,0. 5 mg·L-1,1. 0 mg·L-1,1. 5 mg·L-1 and 2. 0 mg·L-1 of target controlled infusion ( TCI) of propofol, respectively. Narcotrend index ( NI), mean arterial pressure (MAP),heart rate (HR) and t [the time from t1(the time of awareness beginning) to the end of awareness] at t0(the time of adjusting propofol),t1,t2(the period of awareness),t3(wake period end 5 min) were recorded. Elimination of explicit memory after surgery was followed up. Results There were no significant differences in t and NI between groups R1,R2 and R3(P>0. 05). NI of groups R4 and R5 was significantly lower than that in groups R1,R2 and R3(P<0. 05),but t of groups R4 and R5 was longer than that in the other groups (P<0. 05). The MAP,HR and explicit memory of groups R3,R4 and R5 were lower than those in groups R1 and R2 (P<0. 05),but there were no significant differences between groups R3,R4 and R5 (P>0. 05). Conclusion Target controlled infusion of remifentanil 2. 4μg·L-1 combined with TCI propofol 1. 0 mg·L-1 does not affect the wakening controllability. The circulation was steadier and explicit memory could be eliminated during intraoperative awakening.

Objective To study comprehensive nursing meassures for small area of diabetic foot ulcer. Methods A total of 58 patients with small area of diabetic foot ulcer in our department were divided into two groups.The comprehensive nursing group (CN group,30 cases) adopted comprehensive nursing and treatment as follows, surgical dcbridement, infrared radiation of wound surface,sprinkling of growth factors(bFGF and rhEGF),covered by hydrocolloid dressing(Algoplaque).The control group(28cases) received hydropathic compress with 0.5% povidone iodine or 5% furacillin solution.Wound heal-ing progreasion,average healing time and the positive rate of wound germiculture of the two groups were observed. Results The average healing time of the CN group was (29.6±9.4)d,which was shorter than that of the control group,( 39.2±13.5 )d, P < 0.05. Statistical difference existed in the positive rate of wound germiculture at the 7th day and the 14th day between the two groups (P < 0.05). Conclusions Routine medical treatment and general nursing measures plus surgical debridement,infrared radiation of wound sur-face,sprinkling of growth factors and hydrocolloid dressing possess facilitative healing effect for small area of diabetic foot ulcer.

Objective To investigate the feasibility of Narcotrend-guided application of small dose of dexmedetomidine ( DEX) for sedation during combined spinal-epidural anesthesia for elderly patients. Methods Fifty cases of ASA II or Ⅲelderly patients were randomly divided into treatment group and control group (25 patients of each group). After combined spinal-epidural anesthesia, both groups received continuous intravenous infusion of DEX, at 0. 4 μg·kg-1 in 10 min, and then the rate was lowered to 0. 4 μg·kg-1 per hour. For the treatment group, infusion rate was adjusted to reach a Narcotrend Index (NTI) of 75-85, and for the control group, infusion rate was adjusted to reach an OAA/S score of level 3-4. MAP, HR, RR, SpO2 , NTI and OAA/S score were recorded at the beginning of DEX treatment ( t0 ) , 10 min ( t1 ) , 20 min ( t2 ) , 30 min ( t3 ) , and 60 min ( t4 ) after the beginning of DEX treatment, and at the end of surgery ( t5 ) . The incidence rates of adverse events including bradycardia, hypotension, low oxygenation, and respiratory depression were also recorded. The patients were followed up until 24 h after surgery to record loss of memory about the surgical events. Results In comparison with t0 , NTI and MAP of both groups significantly decreased at t1-t5(P<0. 01). Comparison between the two groups showed no difference in MAP at each time point, and NTI of treatment group was higher than that of control group at t2-t5(P<0. 05). In comparison with t0, OAA/S of both groups significantly decreased at t1-t5(for t1, P<0. 05;for t2-t5, P<0. 01). Comparison between the two groups showed no difference in OAA/S at each time point (P>0. 05). Follow-up at 24 h after surgery observed total amnesia in 72. 0% of DEX group patients and in 76. 0% of the control group, without significant difference (P>0. 05). Conclusion Sedating elderly patients undergoing spinal-epidural anesthesia with DEX under the guidance of Narcotrend is safe and feasible, and the patients can be sedated properly.

Objective To carry out a molecular screening of Chinese common deafness gene mutations in Chinese pregnant women group,so as to expatiate on the content,provide molecular epidemiological data,reduce the birth rate and provide a theoretical basis to the deaf children. Methods The molecular detection was done to the pregnant women underwent normal antenatal care in our hospital,using gene chips to screen the four com?mon deaf genes(GJB2,GJB3,SLC26A4 and mitochondrial 12S rRNA)in China;then,the newborn infants carrying mutations were treated with the hearing screening,using the methods of Otoacoustic Emissions(OAE)and Brainstem Auditory Evoked Potentials(BAEP),and the husbands of mutation carrying pregnant women were adopted molecular testing of the deaf susceptibility genes in order to investigate the correlation of the rate of pregnant women carrying the mutant genes and newborn infants deafness. Results Totally 2 067 cases of pregnant women were accepted to do the molecular screening,there were 110 cases of deafness mutations detected(5.320%),in which GJB2 gene(67 cases),GJB3 gene(6 cases), SLC26A4gene(33 cases),mitochondrial 12SrRNAgene(4 cases)mutation detection rates were 3.240%,0.290%,1.600%and 0.190%,respec?tively;especially:GJB2gene 235 del C,GJB2gene 299 del AT double mutant 1 case;GJB2gene 299 del AT,GJB3gene 538 C>T double mutant 1 case;GJB2 gene 235 del C,SLC26A4 gene IVS7?2 A>G double mutant 1 case. About 108 cases children newborn accepted to do the hearing screening,in which 3 cases had problems with the left ear,3 cases with the right ear,and 4 cases with the double ears. Conclusion The use of ge?netic deafness gene chip to do the molecular diagnostics in pregnant women can be convenient,fast and efficient for prenatal diagnosis of deafness, which provides a theoretical basis and good method for reducing the birth rate of deaf children and should be popularized more widely.

Objective To investigate the value of copy number variation analysis based on next-generation sequencing (NGS-CNVA) in the genetic analysis of missed abortion chorionic villi. Methods From August 2012 to May 2014, chorionic villi from 74 cases of missed abortion at 6-13 gestational weeks in Haidian Maternal and Child Health Hospital were collected and analyzed by karyotype analysis and NGS-CNVA. The results of the two methods were compared. Results (1) Karyotype analysis was carried out for the villi from the 74 missed abortion patients. Thirty cases were euploid, 26 cases were aneuploid, while 18 cases had structural abnormalities. The resolution of the karyotyping was 320 bands and the average report time was 22 days. (2) All of the 74 samples obtained NGS-CNVA results and the report time was 7-10 days. (3) The NGS-CNVA results of 56 cases were consistent with karyotype. Among them, 28 cases (28/56, 50%) had no copy number variants (CNV), and 19 cases (19/56, 34%)had CNV between 1 Mb and 10 Mb. 9 cases (9/56,16%) had CNV≥10 Mb found by NGS-CNVA, but not found by karyotyping. (4) According to the results of NGS-CNVA, karyotype were reviewed. The reviewed results found 7 cases with CNV<10 Mb and 3 cases with CNV≥10 Mb in 30 cases which got normal karyotype results at the first analysis. (5) Among the 18 cases of structural abnormalities, 6 cases were Robertsonian translocation. Sequencing technology could confirm the specific area of chromosome deletion/duplication in 8 cases, but could not locate them. Conclusions NGS-CNVA has lower failure rate, higher resolution, lower specimen requirement and shorter report time than karyotype analysis when used for the genetic analysis of missed chorionic villi . NGS-CNVA could be a useful genetic analysis method for the missed abortion villi.

This study aimed at investigating the utilization of TCM services and exploring the influencing factors,such as education,economic condition,health condition,attitude to TCM treatment and TCM health literacy,of TCM treatment-seeking behavior in the elders in Zhejiang Province.In this study,a cross-sectional study with stratified sampling was adopted for the further investigation of the elders over 55 years by questionnaire.The questionnaire contained four aspects:1.demographic information:gender,age,education,pension mode,medicare and self-evaluation of economic level;2.health status:self-evaluation of health and current diseases;3.attitude to TCM treatment:Would you accept the TCM health services? 4.health literacy:self-made KAB questionnaire including health knowledge,attitude and behavior.Nine hundred and fifty questionnaires were issued and 945 valid questionnaires were returned.Among them,four hundred and eighty-four cases were male and 461 were female.The average age was 72.0 ± 8.9 years with a low level of education,mainly junior high school or lower (88.3％).Over the past year,only 50.11％ elders sought for TCM treatment.Generally speaking,age,gender,education,pension mode and health behavior showed no significant association with TCM treatment.The elders seeking for TCM treatment over the past year held favorable attitude to TCM treatment and high economic status,yet,with poor health status,high prevalence and health literacy (or health attitudes).It was concluded that the utilization rate of TCM services in the elders in Zhejiang Province was not optimist,probably resulting from the lack of publicity and market competitiveness of TCM.Therefore,TCM services should be promoted to meet the health needs of the elders and enhance the utilization rate of TCM services for the achievement of a significant role in the aging society in China.
