Objective: To compare postoperative recovery situation between laparoscopic radical resection and conventional open surgery for patients with colorectal cancer and determine the optimal surgery scheme. Methods: 96 patients with colorectal cancer were divided into observation group (48 cases)and control group (48 cases) according to the random number table method. The patients of observation group were treated by using laparoscopic radical resection while the patients of control group were treated by conventional open surgery. A series of clinical manifestation, such as perioperative situation, abdominal pain, recovery situation, complication, pre-and post operative nutrition and quality of life, of these patients were compared between the two groups. Results: The operation time, average bleeding volume, postoperative exhaust time and hospitalization time of the observation group were significantly less than those of the control group (t=5.583, t=48.934, t=7.347, t=4.862; P<0.05). The incidence of abdominal complication of observation group (8.3%) was significantly lower than that of the control group (27.1%) (x2=5.79, P<0.05). The incidence of delayed healing of incision was 6.3% in observation group, which was significantly lower than that (20.8%) of control group (x2=4.36, P<0.05). For observation group or control group, the serum ALB, PA and LC of post-operation, respectively, was higher than those of pre-operation in 1 week after operation. And serum ALB, PA and LC of observation group, respectively, was significantly higher than that of control group (t=4.628, t=3.642, t=3.412; P<0.05). Compared with before operation, physical function, role function, emotional function, cognitive function and social functionthe quality of life of the two group were obviously improved, on the other hand, all of these aspects of the observation group were significantly higher than those of the control group (t=-12.845, t=-7.634, t=0.5001, t=-4.096, t=-2.647, P<0.05). Conclusion: Compared with the traditional open surgery for patients with colorectal cancer, the postoperative recovery of laparoscopic radical resection is better, more obvious and more effective for them.

Objective To assess left ventricular systolic and diastolic function in patients with hypertrophic cardiomyopathy(HCM) with the aid of pulsed Doppler tissue imaging (DTI) to measure the four sides of mitral annular. Methods Thirty subjects with HCM and Twenty five age and sex matched controls were performed 2D and Doppler echocardiography . Two groups were studied with pulsed tissue Doppler imaging of the 4 sides of the mitral annulus (septal, lateral, inferior, anterior) in 4 and 2 chamber views. The velocities of systolic wave(Sa)、early diastolic filling wave (Ea)、late filling wave (Aa) and isovolumetric relaxation time were measured by DTI. Results Compared with normal control group, HCM group shows: (1) conventional data: LV wall thickness and mass indices were significantly greater. There were no significant difference in mitral flow Velocity. (2) DTI: There were more lower velocities of systolic and early diastolic filling wave. But isovolumetric relaxation time、mitra flow velocity / mitral annual early diastolic velocity ratio(E/Ea) increased. The velocities of systolic and early diastolic of septal site were the lowest among the 4 sides of the mitral annular and were the most closely with the average velocities of systolic and early diastolic of mitral annual. In addition, DTI may detect the pseudonormalization of mitral inflow. Conclusions DTI is more sensitive than conventional echocardiogram data and may be clinically used in exactly detecting left ventricular systolic and diastolic dysfunction in patients with HCM

Objective To investigate the relationship between the expression ofα1-antichymot-rypsin (α1-ACT)in plasma and postoperative cognitive dysfunction(POCD).Methods The cognitive function of 64 patients undergoing operation under general anesthesia was evaluated by a battery of cognitive assessment instruments(BCAI)and the levels ofα1-ACT were measured at the time 1 d pre-operatively and 7 d and 3 months postoperatively.The patients were randomly divided into two groups:30 patients in ulinastatin group (group U)were injected with 10 000 U/kg ulinastatin,which was dissolved in 100 ml saline,within 20 min at the time of 30 minutes before induction;while control group (group C)were injected with the same volume saline.Results There was no significant differ-ence between the expression of α1-antichymotrypsin in patients with POCD and in control patients at the time before operation.Compared with control patients,the levels of α1-ACT in patients with POCD at the time of 7 d and 3 months postoperation were significantly higher (P <0.05).The levels of α1-ACT at 7 d postoperation were significantly higher than that preoperatively in both groups (P <0.05).The incidence of POCD in group U were significantly lower than that in group C,at the time of 7 d and 3 months after surgery (P <0.05).Conclusion POCD is associated with high expression of plasma α1-ACT.

Objective To investigate strain and strain rate of right ventricular(RV)based on twodimensional image by velocity vector imaging in normal subjects.Methods Thirty-two healthy adults were rolled in this study.Echocardiographic images in 4 chamber view were analyzed by conventional manual tracing for volumes and ejection fractions,which were also measured by velocity vector imaging.Myocardial velocity,strain rate,and strain were determined at the basal,mid,and apical segments of the RV free wall and ventricular septum by velocity vector imaging.Results RV ejection fractions obtained with manual tracing correlated strongly with the same indexes obtained by velocity vector imaging method in all subjects(r=0.91,P＜0.01).The strain and strain rate value of middle segment and basal segment in RV free wall were higher than those of apical segment.There were same trend in ventricular septal.The strain and strain rate of middle segment and basal segment in RV free wall were higher than those of homologous segments in ventricular septal,but the indexes of apical segment in free wail and septal had no difference.The strain and strain rate in RV were not correlated with age.Conclusions Velocity vector imaging could accurately and quantitatively assess the strain and strain rate of RV.

ObjectiveTo observe the curative effect of Xiangshaliujunzi decoction on critically ill patients with gastrointestinal dysfunction accompanied by spleen deficiency syndrome of traditional Chinese medicine (TCM) and its influence on tumor necrosis factor-α(TNF-α) and interleukin-6 (IL-6).Methods Forty-eight critically ill patients admitted to Department of Emergency Intensive Care Unit (EICU) in Zhejiang Provincal Hospital of Traditional Chinese Medicine Xiasha Campus from February to December 2015 were enrolled, and they were randomly divided into observation group (26 cases) and control group (22 cases) by random number table method. The patients in both groups were given routine emergency western therapy, and in the observation group, additionally, Xiangshaliujunzi decoction (ingredients: codonopsis pilosula 20 g, atractylodes macrocephala koidz 12 g, poria cocos 12 g, radix glycyrrhizae preparata 4 g, rhizoma pinelliae preparatum 6 g, pericarpium citri reticulatae 5 g, fructus amomi villosi 5 g, radix aucklandiae 4 g, rhizoma zingiberis recens 3 pieces) 80 mL was prepared and divided into two parts for nasal feeding, once 40 mL, twice a day, while the patients in the control group received the nasal feeding with the same amount of warm boiled water. Before treatment and 3 days and 5 days after treatment, the gastrointestinal function scores were assessed, and the changes of the levels of plasma TNF-α, IL-6 were recorded.Results There were no statistical significant differences in gastrointestinal function scores, the levels of TNF-α and IL-6 between the two groups before treatment and 3 days after treatment (allP ﹥ 0.05). But 5 days after the treatment, the gastrointestinal function scores, the levels of TNF-α and IL-6 were obviously decreased in two groups, and the degree of decrease in observation group was more significant [gastrointestinal function score: 0.92±0.85 vs. 2.27±0.77, TNF-α (ng/L): 17.7±2.4 vs. 25.0±4.2, IL-6 (ng/L): 16.9±2.4 vs. 25.0±3.4, allP < 0.01].Conclusion Xiangshaliujunzi decoction has therapeutic effect on critically ill patients with gastrointestinal dysfunction and accompanied by spleen deficiency in TCM, the mechanism may be related to decreasing the levels of TNF-α and IL-6, thereby depressing the inflammation.

Objective:To investigate the methylation of CpG island of metallothionein-3 (MT-3) gene in esophageal cancer tissues and normal tissues in middle and south area of Hebei Province and Chaoshan area of Guangdong Province and compared the results with those in low risk area of esophageal cancer. Methods:The blood samples from 10 normal volunteers, 10 embryonic esophageal tissues, 20 esophageal mucosa tissues from normal subjects in low risk area as well as 30 fresh surgical specimens of esophageal cancer and 30 normal marginal tissues in the high risk middle-south Hebei Province and Chaoshan area were collected. Methylation-specific polymerase chain reaction (MSP) was used to detect the methylation status of the CpG island of MT-3 gene in these samples. Its relationship with clinicopatho-logical features was analyzed. Results:There were 20 (33.3%) cases with MT-3 methylation in the marginal tissues of esophageal cancer from high-risk area, which was higher than that in the normal mucosa from low-risk area (P=0.013). And there were 49 (81.7%) cases with MT-3 methylation in esophageal cancer tissues, which was higher than that in normal marginal tissues (P<0.001). But there was no significant difference in the methylation degree between middle-south of Hebei Province and Chaoshan area (P=0.739). Conclusion:MT-3 methylation widely exists in esophageal mucosa and carcinoma tissues. Acquired stimulus may be the main cause of these methylations.
