The two groups were compared in terms of the curative effect. Result The response rates in the experiment and control groups were 87.1%and 56.7%, respectively (P<0.05). Conclusion Acupoint application with Chinese herbs to treat constipation in patients with advanced tumors has a better therapeutic effect.

Objective To investigate the clinical efficacy and safety of hysteroscopy surgery combined with methotrexate (MTX) for treating the patients with cesarean scar pregnancy(CSP).Methods The clinical data of 64 patients with CSP were retrospectively analyzed.The patients were divided into observation group (46 cases) and control group (18 cases) according to treatment methods,the control group was given the therapy of local pregnancy intracapsular MTX combined with uterine curettage,and the observation group was given the therapy of local pregnancy intracapsular MTX combined with lesions removed surgery by hysteroscopy.The intraoperative blood Ioss,epistrophy time of β-human chorionic gonadotrophin (hCG),hospitalization time,clinical efficacy of the two groups were observed.Follow-up for 6 months the menstruation of the two groups was observed.Results The total effective rate in observation group was significantly higher than that in control group [100.0％ (46/46) vs.66.7％ (12/18),x2 =16.920,P ＜ 0.01].The intraoperative blood loss,epistrophy time of β-hCG and hospitalization time in observation group were significantly lower than those in control group [(35.46 ± 11.63) ml vs.(176.78 ± 57.96) ml,(21.04 ± 6.79)d vs.(39.65 ± 12.79) d,(13.89 ±4.63) d vs.(26.82 ±8.94) d,P＜0.01].The observation group had a successful surgery and no complications.In the control group,4 cases occurred uterine curettage intraoperative bleeding,2 cases underwent open lesion resection and then were forced to line hysterectomy.The rate of menstruation in observation group after operation 30-39 d was significantly higher than that in control group [84.8％ (39/46) vs.25.0％ (4/16),P ＜ 0.01].Conclusions Hysteroscopy surgery combined with MTX for treating the patients with CSP has exact clinical effect.It is safe and reliable,and is worthy of promotion and application.

Objective To investigate the impact of acupoint massage on the vital signs of patients with angina pectoris in coronary artery heart disease (CHD) during the operation. Methods Using non-concurrent cohort controlled design, 38 cases who with angina pectoris in CHD received interventional therapy, from June to September in 2015, in the therapy rooms of our hospital were selected as control group and received routine nursing. 38 cases who with angina pectoris in CHD received interventional therapy, from October 2015 to January 2016, in the therapy rooms of our hospital were selected as intervention group and received acupoint massage based on routine nursing. Heart rate and blood pressure of patients in two groups were monitored and recorded during the operation. Results Compared with control group, systolic blood pressure of patients in intervention group decreased obviously (143.26±17.67 vs. 153.18 ± 19.35) mmHg (1mmHg=0.133 kPa), diastolic blood pressure decreased obviously (83.16 ± 12.29 vs. 93.82 ± 16.54), and heart rate decreased obviously (71.89 ± 13.90 vs. 79.05 ± 12.63) mmHg (t=2.33, 3.19, 2.35, P<0.05 or 0.01). Conclusions Acupoint massage can effectively reduce heart rate and blood pressure of patients with angina pectoris in CHD during the operation, relieve patients' anxiety, and help for smoothing operation, shortening operation time and reducing operation risk.

Objective To study the correlative risk factors of uterine cavity adhesion (UCA),and observe the clinical efficacy of hysteroscope operation treatment of UCA.Methods According to whether the occurrence of UCA,120 patients with spontaneous abortion were divided into two groups.The correlative risk factors of UCA were analyzed by multiple factors regression analysis.The patients with UCA were treated with hysteroscope operation treatment,and the clinical efficacy were observed.Results In 120 patients with spontaneous abortion,46 patients (38.3％) had UCA.Single factor analysis result showed:UCA was correlated with pelvic inflammation,gravidity,uterine cavity suction negative pressure,uterine cavity suction time (P ＜ 0.05),but UCA was not correlated with age,years of education,occupation,gestational weeks,menarche age (P＞ 0.05).Multiple factors analysis result showed:UCA was correlated with pelvic inflammation,uterine cavity suction negative pressure,uterine cavity suction time (P ＜ 0.05).The total effective rates of hysteroscope operation treatment of mild,moderate and severe UCA were 100.0％ (18/18),93.8％ (15/16)and 83.3％ (10/12) respectively,there was no significant difference among them (P ＞ 0.05).Conclusions Along with the increasing of uterine cavity suction negative pressure and extension of uterine cavity suction time,the risk of UCA is also increasing,pelvic inflammation is also an independent risk factor of UCA.Hysteroscope operation treatment of UCA has better curative effect,especially for mild UCA,it is worth clinical application.

Objective To explore the clinical value of laparoscopic supracervical hysterectomy (LSH). Methods From July 2006 to September 2007,78 cases of LSH and 59 cases of abdominal supracervical hysterectomy (ASH) were performed in our hospital. The clinical data of the patients,including intraoperative blood loss,operation time,recovery time of bowel movement,postoperative time of out-of-bed activity and postoperative hospital stay,were analyzed and compared between the two groups.Results No significant difference was found on the mean intraoperative blood loss between the LSH group and ASH group [(65.1?25.5) ml vs (72.9?23.6) ml,t=-1.830,P=0.069]. Whereas,the LSH group had significantly longer operation time and earlier recovery of the gastrointestinal function [(80.3?29.6) min vs (62.4?13.1) min,t=4.332,P=0.000;and (26.5?8.5) h vs (30.9?7.0) h,t=-3.232,P=0.001]. Furthermore,the LSH patients had out-of-bed activity and were discharged from hospital significantly earlier than the ASH group [(32.8?6.7) h vs (40.4?9.7)h,t=-5.421,P=0.000;and (7.1?0.6) d vs (7.9?0.5) d,t=-8.291,P=0.000]. No major complication occurred in both the groups. Conclusions LSH shows great advantages over ASH. As long as surgeons are skilled in laparoscopic operation,LSH can be an ideal procedure for hysterectomy.

This paper sets out to summarize the literatures based on immobilized enzyme biochromatography and its application in inhibitors screening in the last decade.In order to screen enzyme inhibitors from a mass of compounds in preliminary screening,multi-pore materials with good biocompatibility are used for the supports of immobilizing enzymes,and then the immobilized enzyme reactor applied as the inmobilized enzyme stationary phase in HPLC.Therefore,a technology platform of high throughput screening is gradually established to screen the enzyme inhibitors as new anti-tumor drugs.Here,we briefly summarize the selective methods of supports,immobilization techniques,co-immobilized enzymes system and the screening model.

Objective To find the normal range and features for auditory brainstem responses(ABR)of infants within six months,and the basic parameters for identifying the hearing impaired infants.Methods May 2006 to May 2008,60 normal infants and 20 normal adults received the ABR tests.The infants were divided into three groups:group A(6 weeks),group B(3 months)and group C(6 months).Each group consisted of 20 infants(40 ears)and the ABR data were statistically analyzed.Results At 100 dB nHL,the waveⅠ,Ⅲ,Ⅴ latencies of ABR for 6-week infants respectively were 1.49?0.08 ms,4.42?0.16 ms and 6.61?0.25 ms,for 3-month infants,1.47?0.07 ms,4.35?0.20 ms and 6.50?0.25 ms,for 6-month infants,1.45?0.07 ms,4.17?0.15 ms and 6.32?0.22 ms.At 80 dB nHL,the waveⅠ,Ⅲ,Ⅴ latencies of ABR for 6-week infants were 1.63?0.08 ms,4.52?0.17 ms and 6.74?0.26 ms,respectively,for 3-month infants,1.64?0.11 ms,4.44?0.20 ms and 6.67?0.26 ms,for 6-month infants,1.60?0.11 ms,4.27?0.16 ms and 6.43?0.24 ms.As the intensity of stimulating signals decreased,the peak latency of ABR became more delayed.The peak latencies of Ⅲ,Ⅴ waves and interval peak latencies of Ⅰ-Ⅲ and-Ⅴ waves for the infants were more delayed than those for adults,and became shorter with the increase of the infants' ages,but they failed to reach adults' levels even for 6-month infants.However,the length of wave Ⅰ of ABR for infants of different months was close to that for adults.The thresholds of ABR for the infants of different ages were not significantly different,all being close to the values for adults.Conclusion This study has analyzed the ABR wave features for the infants of three ages and this can help to define the reference ranges for the infants and to provide the parameters for early diagnosis of hearing loss among the infants.

Objective To investigate the retention level and its influencing factors for male nurses,and explore effective strategies to increase retention level of male nurses.Methods A sample of 610 male nurses from many hospitals in Tianjin were investigated with the self-designed demographic questionnaire,Retention Scale and Perceived Organization Support.The results underwent analysis.Results Male nurses' retention score was (20.71±4.00) points.Single factor analysis found that marriage,age,number of children,time engaged in nursing work,the working years in present position,the purpose of the work had statistically significant influence on retention scores of the male nurses.Multiple linear regression analysis showed that marriage,professional and technical titles,the purpose of work,work support and value identification were the predictive effect on the degree of the retention.Conclusions The retention of male nurses in Tianjin was in the medium level.Hospitals and all relevant departments should take effective measures,improve the professional sense of worth of the male nurses and job satisfaction,in order to enhance the man nurses' retention rate,promote the sustainable development of the nursing team construction.

Objective We aim to objectively evaluate the influence of six-character formula on patients with stable chronic obstructive pulmonary disease (COPD).Methods The randomized controlled trials (RCTs) which investigated the influence of six-character formula on patients with COPD were electronically searched in the databases such as China National Knowledge Infrastructure (CNKI),Chinese Science Technology Periodical Databases (VIP),Wanfang Data,PubMed,The Cochrane Library (Issue 6,2014) and ELSEVIER.According to the inclusion and exclusion criteria,the references was screened,the data were extracted and the methodological quality of the included articles was assessed.Then,Meta-analy-sis was performed using RevMan 5.3 software.Results A total of 10 studies involved,578 patients were included.The result of Meta-analysis showed that compared with the control group,six-character formula significantly improved six-minute walk distance,forced expiratory volume in a second (FEV1) and FEV1 predicted value,reduced the score of activity limitation and the impact of the disease in St George's respiratory questionnaire (SGRQ).the value of MD and 95％CI were 22.62 (10.49-34.75),0.10 (0.01-0.18),3.08 (0.18-5.97),8.69 (4.09-13.83),7.60 (2.34-12.85).However,there was no statistical difference in the score of symptom.Conclusions Six-character formula plays a significant role in the treatment of stable COPD.However,more studies in large scale and high quality are needed to verify the result.
