Objective To analyze the association of gastrointestinal symptoms and sleep disturbance after Wen-Chuan earthquake. *Methods Using random sampling method, compared with Beijing publics at the same time, within two weeks, questionnaire was performed in the disaster area population.Gastrointestinal symptoms were diagnosed according to the Rome Ⅲ standard, and were analyzed in relation to sleep investigation. Results Among 956 disaster area individuals, 459 (48.0%) have gastrointestinal symptoms. Among 1021 Beijing publics, the corresponding number was 78(7. 6% ) ,which was significantly lower. The main gastrointestinal symptoms included abdominal pain ( 14. 0% ), distension ( 12. 1% ),constipation ( 10. 3 % ), heartburn (8. 6% )and dysporia (8. 3% ). Compared with Beijing publics (24. 4% ),the disaster area publics ( 83.7% ) with gastrointestinal symptoms had significant differences in sleep disturbance (P ＜0. 05 ). Early awakening with acratia had significant differences in disaster area publics (P ＜ 0. 05). Conclusion There was relatively high incidence of gastrointestinal symptom after Wen-Chuan earthquake. The incidence of gastrointestinal symptom was related to sleep disturbance, and gastrointestinal symptoms were related to early awakening with acratia.

Objective To evaluate the effect of clinic-pathological variables on prognosis and recurrence of the aged women suffered from borderline epithelial ovarian tumors. Methods The clinical and follow-up data of 102 cases were analyzed retrospectively. Univariate and multivariate logistic regression analysis were used to assess independent prognosis and recurrence factors.Results The postoperative accessory treatment, peritoneal implantation and lymph nodes metastasis could influence the 5-year survival rate(χ2=19.311, 11.054, 18. 559, all P＜0.01). The surgery procedure, peritoneal implantation, lymph nodes metastasis and microinvasion could influence the recurrence rate(χ2=23.606, 23.583, 25.774, 23.583, all P＜0.01). The logistic regression model showed that the postoperative accessory treatment and peritoneal implantation were the two independent prognosis factors (OR=0.060, 35.319, all P＜0.01). The surgery procedure,peritoneal implantation and microinvasion were the three independent factors affecting recurrence(OR =0.001, P＜0.05;OR=60.952, P＜0.05;OR=88.874, P＜0.01). Conclusions The early standard treatment on borderline epithelial ovarian tumors of the aged women have an excellent prognosis, the risk of recurrence remains in some patients. We emphasize that these patients with highrisk factors should be main surveillance population.

Objectives To investigate the methods of protecting external branch of the superior laryngeal nerve (EBSLN)in carotid endarterectomy and to observe the effect of using these methods in clinical surgery. Methods EBSLN (20 sides)of 10 heads of corpse were studied by using microanatomy from January 2013 to December 2013. The occurrence probability of EBSLN on the lower edge of posterior belly of digastric muscle,medial edge of external carotid artery and upper edge of superior thyroid artery in anatomy triangle was analyzed. The distances from the midpoint of the EBSLN to carotid bifurcation, mandibular angle and mastoid tip were measured. Sixty-five patients with carotid endarterectomy in Tianjin Huanhu Hospital from December 2013 to November 2014 were treated with the protective methods of the relevant EBSLN by using anatomy triangle as a mark. Whether the patients had injury symptoms of EBSLN were followed up after procedure. Results (1)The occurrence probability of 20-side EBSLN in anatomy triangle was 95%(19 sides). The midpoint of EBSLN in the anatomy triangle at the posterior mandibular angle was median 0. 34 (-1. 62 to 2. 43)cm,at the inferior mandibular angle was 1. 28 (-1. 33 to 3. 42) cm,at anterior mastoid tip was 2. 84 (0. 51 to 5. 14)cm,at inferior was 4. 51 (2. 82 to 6. 39)cm,and at anterior superior of the carotid bifurcation was 1. 64 (0. 57 to 3. 78)cm. (2)65 patients who underwent carotid endarterectomy used the protective methods of intraoperative EBSLN. There was no manifestation of EBSLN injury at 3 weeks to 9 months after procedure. Conclusion In carotid endarterectomy,taking an anatomic triangle as a symbol,it is no more than 2 cm of the anterior superior of carotid bifurcation during the separation process. As for the patients with higher or lower position of carotid bifurcation,in the range of crossing rear mandibular angle 0. 50 cm or below the mastoid tip 4. 50 cm for arterial separation should be avoided,and this can effectively protect EBSLN.

The atrio-ventricular valves of the normal heart of 100 Chinese adult cadavers were studied. The right atrio-ventricular (tricuspid) valve was found to be composed of four main cusps in 80% of the cases,three main cusps in 19%,and two main cusps in 1%.In certain cases,small additional intermediate cusps had been found.They were derived from the main cusps and situated in the angles between the medial and anterior wall, or between the medial and posterior wall of the right ventricle.These may be called “cuspi accessoria”.The anterior accessory cusp was present in 31% and the posterior accessory cusp in 27% of our preparations.If the total number of the main and acces- sory cusps of the right a—v valve was considered,four cusps occurred in 42%,five in 36%,three in 13%,six in 8% and two in 1%. The left atrio-ventricular (mitral) valve consisted of two main cusps.But frequent- ly there were conspicuous ruptures on the posterior cusp in our specimens,with the ex- ception of twelve cases (12%).Thus,the posterior cusp may be consisted of one greater leaflet and one to four smaller leaflets.Based on this character,the posterior cusp of the left a—v valve may be grouped into three types:(1)the middle portion of the posterior cusp was well developed in 48%;(2)the antero-lateral portion was well developed in 35%;and (3) the postero-medial portion was well developed in 17%. The anterior cusp of the left a—v valve separated into two equal parts had been found in one case (1%). The height of the cusps and of the commissural margins,where the neighboring cusps were joined,had been measured.Discussions have been made on the principles of the differentiation between the main cusp and the accessory cusp.

Objective To evaluate the role of Na+-K+-2Cl-cotransporter isoform 1 (NKCC1) in neurons in sevoflurane-induced epileptiform electroencephalogram (EEG) activity in the cortex of neonatal rats.Methods Twenty-four neonatal Sprague-Dawley rats,aged 4-6 days,weighing 8-15 g,were randomly divided into 3 groups (n =8 each) using a random number table:control group (group C),sevoflurane group (group S),and NKCC1 inhibitor bumetanide + sevoflurane group (group B).After electrodes were placed correctly,EEG was monitored continuously.At 30 min of monitoring,normal saline 3 μl/g was injected intraperitoneally in D and S groups,and bumetanide 10 μg/g was injected intraperitoneally in group B.At 60 min after the end of intraperitoneal administration,anesthesia was induced with inhalation of 6％ sevoflurane for 3 min and maintained with inhalation of 2.1％ sevoflurane for 1 h in group S and group B.The total duration of seizures,the duration of a single episode,the number of episodes of electroencephalographic seizures,and the amplitude and frequency of spike-and-wave were recorded.Results Seizures were not detected in group C,and no spike-and-wave was found in group B.Compared with group C,the incidence of seizures in S and B groups (75％ and 25％,respectively) and incidence of spike-and-wave in group S (100％) were significantly increased (P＜0.05).Compared with group S,the incidence of seizures and spike-and-wave was significantly decreased,the total duration of seizures,and duration of a single episode were significantly shortened,and the number of episodes of electroencephalographic seizures was significantly decreased in group B (P＜0.05).Conclusion NKCC1 in neurons may be involved in the formation of sevoflurane-induced epileptiform EEG activity in the cortex of neonatal rats.

Objective:To explore whether perioperative intravenous flurbiprofen axetil can reduce the incidence and intensity of chronic pain for breast cancer atfer surgical treatment. Methods:This randomized, double-blind, controlled trial enrolled 60 patients undergoing mastectomy and axillary lymph node dissection under general anesthesia. All patients accepted Hospital Anxiety and Depression Scale (HAD) tests the day before the surgery to evaluate depression and anxiety. hTe patients were randomly assigned to receive either 50 mg lfurbiprofen axetil intravenously 15 minutes before the surgical incision and 6 hours later (group F) or intravenous 5 mL intralipid as a control (group C). All patients received patient-controlled intravenous analgesia (PCIA) with fentanyl postoperatively. Peripheral venous blood samples were drawn before the surgery, at 4 and 24 h atfer the surgery to detect the plasma level of PGE2 and tumor necrosis factor-α(TNF-α). Postoperative fentanyl consumption, Numerical Rating Scale (NRS) scores and adverse effects were recorded at 2, 6, 12, 24 and 48 h after the surgery. hTe duration and intensity of pain were followed up by telephone at the 2nd-12th month atfer the surgery. Results:The incidence of pain at 2, 4, 6, and 12 months after the breast surgery was 33%, 20%, 15%, and 10%, respectively, and the average pain score was 0.77, 0.57, 0.28, and 0.18, respectively. Compared with group C, the scores of pain in group F were significantly lower at 2, 4, 6 and 12 months postoperatively (F=7.758, P=0.007). The incidence of pain in group F was significantly lower at 2, 4 and 6 months postoperatively (P<0.05). There was no significant difference in the incidence of pain between the groups at 12 months postoperatively (P>0.05). Preoperatively and at 4 and 24 h atfer the surgery, there was no signiifcant difference in the level of TNF-αbetween the two groups (F=0.530, P=0.470);but plasma concentration of PGE2 in group F was significantly lower than that in group C (F=5.646, P=0.021). No patients developed abnormal bleeding, peptic ulcer, impaired liver or renal function and respiratory depression. Conclusion:Perioperative intravenous infusion of 100 mg flurbiprofen axetil can decrease the intensity and incidence of chronic pain for breast cancer atfer surgical treatment.

Objective To explore the value of endothelial dysfunction assessment in predicating major adverse cardiac and cerebrovascular events (MACCE) in peritoneal dialysis (PD) patients.Methods A prospective cohort study included 136 end stage renal disease (ESRD) patients from Jan 1,2009 to Dec 31,2011 was conducted.Endothelial function was assessed by flowmediated dilation (FMD) of brachial artery.Kaplan-Meier method was used to estimate survival rate.The survival difference between the two groups was compared by the log-rank test.Multivariate Cox proportional hazards regression was used to determine the independent risk factors of MACCE.Results In the follow-up period,18 patients in low FMD (FMD≤2.7％) group occurred MACCE,and 13 patients in high FMD (FMD ＞ 2.7％) group occurred MACCE.Compared with high FMD group,MACCE-free survival rate in the low FMD group had a significantly decreased (x2=4.190,P=0.041).Multivariate Cox proportional hazards regression analysis showed that higher level of total cholesterol,lower FMD,longer PD time and higher levels of hs-CRP were all independent predictors of MACCE.Conclusion Reduced brachial artery FMD is an independent risk factor of MACCE,and the application of FMD contributes to the risk stratification of cardiac and cerebrovascular disease in PD patients.

Objective To explore the application value of videolaryngoscope and Macintosh la ryngoscope in double-lumen endobronchial intubation.Methods Eighty patients (50 males,30 females,aged 18-70 years,ASA grade Ⅰ-Ⅲ) of both sexes,scheduled for thoracic surgery and double lumen endobronchial intubation were randomly divided into two groups using a random number table:videolaryngoscope group and Macintosh laryngoscope group.The intubation time,the success rate of intubation,the views of glottis,the hemodynamics during the first 4 minutes of intubation,the number of positive responses to intubation and the incidence of pharyngalgia at 24 h after the operation were observed and compared between the two groups,the condition of oral hemorrhage and the injury of the tracheal walls were recorded as well.Results Compared with videolaryngoscope group,the C-L grade and the success rate of the first intubation of Macintosh laryngoscope group was significantly higher,the intubation time of Macintosh laryngoscope group was significantly shor ter (P＜0.05).In addition,the positive cases of responses to intubation and the incidence of pharyngalgia at 24 h after the operation of Macintosh laryngoscope group were obviously less than those of videolaryngoscope group (P＜0.05).There was no significant difference between the two groups of oral injury bleeding and the injury of tracheal wall and protuberance.At T2,T3,the two groups of MAP were significantly lower than that of T1,and the MAP of videolaryngoscope group was significantly lower than that of t Macintosh laryngoscope group at T2,T3 (P ＜ 0.05).Conclusion Compared with videolaryngoscope,Macintosh laryngoscope is more suitable for the doublelumen endobronchial intubation in patients predicted without difficulty in intubating.

Objective:To observe the effects of acupuncture and moxibustion on ubiquitin-like containing PHD and RING finger domains 1(UHRF1)and DNA methyltransferase 1(DNMT1)in ectopic endometrium of rats with endometriosis(EMS). Methods:Forty Sprague-Dawley rats were randomly divided into a sham operation group with 10 rats and a model-building group with 30 rats according to body mass.EMS rat models were established in the model-building group and then were divided into a model group,an acupuncture and moxibustion group,and a progesterone group,with 10 rats in each group.All rats were fixed by a fixator.The sham operation group and the model group were given normal saline by gavage.The acupuncture and moxibustion group received acupuncture at Xuehai(SP10)and Sanyinjiao(SP6),moxibustion at Guanyuan(CV4),and gavage of normal saline.The progesterone group was given the mixed liquid made of dydrogesterone and normal saline by gavage.After 28 d of treatments,the three diameters(length,width,and height)of EMS rats'ectopic cysts were measured,the cyst volumes were calculated,the volumes before intervention were subtracted,and the difference values were used to evaluate the growth of ectopic cysts.UHRF1 and DNMT1 mRNA and protein levels in normal endometrium,eutopic endometrium,and ectopic endometrium were detected by real-time polymerase chain reaction and immunohistochemistry. Results:There was no significant difference in the ectopic cyst volume difference between the acupuncture and moxibustion group and the progesterone group(P>0.05),but they were smaller than that of the model group(P<0.05).The levels of UHRF1 and DNMT1 mRNA and protein in the ectopic endometrium of the model group were lower than those in the normal endometrium(P<0.05).The levels of DNMT1 mRNA and UHRF1 protein in the eutopic endometrium of the model group were lower than those in the normal endometrium(P<0.05).The levels of UHRF1 mRNA and protein and the level of DNMT1 protein in the ectopic endometrium of the acupuncture and moxibustion group were higher than those in the model group(P<0.05),and the level of UHRF1 mRNA was higher than that in the progesterone group(P<0.05).The level of DNMT1 mRNA in the eutopic endometrium of the acupuncture and moxibustion group was higher than that in the model group(P<0.05).The levels of UHRF1 and DNMT1 mRNA and protein in the acupuncture and moxibustion group were insignificantly different from those in the normal endometrium(P>0.05). Conclusion:Acupuncture and moxibustion may up-regulate the levels of UHRF1 mRNA and UHRF1 and DNMT1 proteins in the ectopic endometrium to the normal level so as to reduce the volume of ectopic cysts and cure EMS in rats.
