Objective To discuss the efficacy of sufentanil combined with propofol in iv anesthesia during laparoscopic cholecystectomy.Methods Totally 182 patients received laparoscopic cholecystectomy.They were divided into two groups according to odd or even number of hospitalization.The control group (81 cases) were given remifentani combined with propofol for iv anesthesia.The observation group (101 cases) were given sufentanil combined with propofol for iv anesthesia.The anesthetic effect of sufentanil combined with propofol for iv anesthesia during laparoscopic cholecystectomy was evaluated by breathing recovery time,opening time,extubation time,VAS scores after 1,6,12 h,and complications during anesthesia.Results Breathing recovery time,opening time,and extubation time of observation group were longer than those of control group (P ＜ 0.05).The VAS scores after 1,6,and 12 h of observation group were lower than those of the control group (P ＜ 0.05).During anesthesia,the proportion of restlessness in observation group was lower than that in control group (P ＜ 0.05).The complication rate of observation group was lower than that of control group (P ＜ 0.05).Conclusion Sufentani combined with propofol has a good anesthetic effect on patients receiving laparoscopic cholecystectomy with mild postoperative pain and less restlessness.It is worthy of clinical use.

Atrial fibrillation (AF) is the most common clinical arrhythmia.Atrial electrical remodeling and structural remodeling are the important mechanisms for AF.The intracellular Ca2+ handling abnormalities play an important role in the induction of triggered ectopic activity and in the activation of Ca2+-related cell signaling which mediates fibrillatory remodeling.In addition,the importance of microRNAs,which are a new class of small noncoding sequences that regulate gene expression,has been found in both electrical and structural remodeling.The new discovery of AF mechanisms are helpful to exploring the effective treatment for AF,showing good prospects for the use of translational perspectives.

The rehabilitation therapeutic method of dysphagia after stroke included movement therapy and compensatory technology (including neurodevelopmental therapy), neuromuscular electrical stimulation, surface electromygraphy biofeedback training, non-invasive brain stimulation, balloon ductal dilatation technique, acupuncture and moxibustion, drug, and surgical treatment. The movement therapy and compensatory technology were the basis of therapy and the upward and forward movements of tongue-throat complex were the core of therapy. The combined treatments of early, initiative, individual, and various methods were emphasized, while the nutrition and the preven-tion and cure of aspiration pneumonia of patients should be paid attention to.

Objectives: To observe the radiological and pathological changes of flow diverting sent implanting into abdominal aortae of rabbits at 3 months and to evaluate the safety of stents for normal arteries of rabbits. Methods: The abdominal aorta beyond the left renal artery opening was showed via preoperative angiography. The flow diverting stents with metal coverage of 35% to 45% were implanted into the abdominal aortae of 20 New Zealand white rabbits. Intravenous digital subtraction angiography was performed at 4 weeks after the procedure. Arterial digital subtraction angiography was performed for all the animals at 3 months and they were sacrificed for histopathological examination. The angiography showed that the diameter changes of abdominal aortae on the stenting sites at different time points were measured and compared. The relationship between the neointima and the metal coverage of local stent were analyzed. Results: The mean diameter of the abdominal aortae before stenting, immediately after stenting, at 4 weeks, and at 3 months were 3.47 ± 0.44 mm, 3.65 ± 0.40 mm, 3.57 ± 0.36 mm, and 3.51 ± 0.30 mm, respectively. There were significant differences among the different time points (P=0.009). The neointima fully covered the stents with a mean thickness of 95 ± 42 μm. They were predominantly composed of smooth muscle cells, collagen fibers, and a small amount of macrophages. The neointimal thickness was positively correlated with the local coverage of the metal stents (r = 0.523; P = 0.001). Conclusion Three months after the implantation of flow diverting stents, the abdominal aorta intima thickened slightly, and the stents were safety for normal arteries of rabbits.

Objective To investigate the influence of ziprasidone combined with amend electric shock on the efficacy and metabolism of patients with first-episode schizophrenia.Methods According to random number table,86 cases with first-episode schizophrenia from July 2013 to July 2016 in the Second Affiliated Hospital of Xinxiang Medical University were chosen and divided into observation group and control group.The patients in observation group were given ziprasidone combined with first-episode schizophrenia,the patients in control group were taken with olanzapine combined with first-episode schizophrenia.The PANSS total score,CGI score,total efficacy,adverse reaction,body mass index,glycometabolism,and lipid metabolism of two groups were observed and compared.Results The PANSS score,CGI score of two groups were all obvious decreased,which had no significant difference,the total efficacy of two groups had no significant difference;The TESS scores were all decreased,and the TESS score of observation group was obviously lower than that of control group (P ＜ 0.05).Compared with before treatment,the BMI,fasting blood sugar,triglyceride,total cholesterol,high/low density lipoprotein and fasting insulin level of observation group after treatment had no obvious significant difference,while the BMI,fasting blood sugar,triglyceride,total cholesterol,low density lipoprotein,and fasting insulin levels of control group had obvious significant difference,and the BMI,fasting blood sugar,triglyceride,total cholesterol,and fasting insulin of observation group were obviously lower than control group (P ＜ 0.05).Conclusion Olanzapine and ziprasidone combined with amend electric shock have obvious efficacy on patients with first-episode schizophrenia,while the ziprasidone had lower adverse reaction and metabolic side effects,which is worth of clinical promotion and application.

Objective:To observe the curative effects and the influences of Yueanxin injection (YAXI, 悦安欣注射液) on acute cerebral infarction (ACI) and on blood rheology separately. Methods:Sixtytwo cases with ACI were randomly divided into treated group ( n=31) which was treated with YAXI and control group (n=31) which treated with tetrameth ylp yrazine injection (川芎嗪注射液) as control. Once a day for 30 days as a therape utic course to both groups.The curative effects and the changes in blood rheology parameter s were observed.Results:The marked effective rate (74.2%) and total effective rate (96.8%) in treated g roup were significantly superior to those (38.7% and 67.7% respectively) in cont rol group (P<0.05 or P<0.01). The improvements of blood rheology param eters in tr eated group were significantly better than those in control group (P<0.0 5 or P<0.01).Conclusions:The curative effects of YAXI on ACI are sufficient.
