Objective To observe the effect of chewing gum on EGG,blood motilin and anus exhausting after laparoscopic abdominal surgery. Methods 200 patients after laparoscopic cholecystectomy were randomly arranged into chewing gum group (Group G): to start chewing gum for 30 min at breakfast time on first day after operation, and also at lunch and dinner time, and stopped until the first anus exhausting, and the control group(Group C): no chewing gum. The time between endpoint of operation to first anus exhausting was recorded; blood motilin and electrogastrography (EGG)on the morning of 1,2,3 days postoperation after chewing gum was detected. Results The time between endpoint of operation to first anus exhausting was not significantly different between two groups, compared with the control group, blood motilin significantly improved on the first day and the second day,but there was no difference between two groups on 3rd day; EGG was no different in all three days between two groups. Conclusions Chewing gum doesn't improve bowel function after laparoscopic abdominal surgery.

Objective To explore the relationship between dopaminergic axon terminal and GABAergic neurons and explore the neuroanatomic mechanism of their effects in schizophrenia. Methods The co-location and the association of dopaminergic axon terminal and GABAergic neurons in the basolateral nucleus (BL) of rat amygdala were examined by using double labeling immunoelectron microscopic techniques. Dopaminergic axon terminal and GABAergic neurons were labeled with the antidopamine (anti-DA) and the anti-glutamic acid decarboxylase (anti-GAD) antibodies respectively. Results 43% of the DA-input synapses was observed to relate directly or indirectly to GAD-immunoreactive(IR) dendritic structures(DA/GAD), which includes single (38%), convergent (30%), serial (20%), and axoaxonic (12%) contact types.And 57% of the DA-input synapses was found to associate with unlabeled elements (DA/UE), which includes unlabeled perikarya (10%), dendrites (82%) and axons (8%). All of the synapses that show DA-IR terminals profiles were found to be symmetric (inhibitory) synapses.Conclusion These results suggest that the dopaminergic system in the BL of rat amygdala controls the mediations of the GABAergic interneurons via symmetric synapses. In addition, the dopaminergic axon terminal associates with the glutamatergic projection neurons and exerts influence on its activity.

OBJECTIVE:To promote hospital rational drug use. METHODS:A total of 1 359 ADR cases submitted to State ADR Center by our hospital from 2005 to 2007 vial network system were analyzed statistically in respect of patients' age and sex,the drugs involved,routes of administration,ADR-involved organs or systems,and turnover etc. RESULTS:Of the total 1 359 cases,25.75% were induced by antimicrobial drugs and 55.33% were induced by intravenous route. The lesions of skin and its accessories were the predominant presentation of ADR,and the majority ADR cases had a good turnover. CONCLUSION:The incidence of ADR can be reduced by strengthening the education on and monitoring of ADR as well as the sense of responsibility of medical staff.

ObjectiveTo investigate the clinical value of serum cystatin C(CysC) and urinary microalbumin(MA) in the diagnosis of early renal function injury in patients with essential hypertension.MethodsOne hundred and twenty patients with essential hypertension(hypertension group) were divided into three groups by the results of blood pressure:grade 1 with 48 cases,grade 2 with 47 cases,grade 3 with 25 cases.Thirty healthy subjects were selected as control group.Serum CysC,urinary MA and serum creatinine (Cr) were detected in all subjects.ResultsThe serum CysC and urinary MA in grade 1,2 and 3 hypertension group [(1.57 ±0.48),(2.12 ±0.72),(2.91 ± 1.09) mg/L and(18.12 ±5.43),(29.01 ±8.07),(46.06 ± 13.21 ) mg/L] were obviously higher than those in control group [ (0.71 ± 0.23 ),(9.35 ±5.17)mg/L](P＜ 0.05).The serum Cr had no significant difference between grade 1,2,3 hypertension group and control group (P ＞ 0.05 ).Serum CysC was positively correlated with urinary MA in hypertension group (r =0.613,P ＜ 0.05),serum CysC and urinary MA were both negatively correlated with estimated glomenlar filtration rate (eGFR)(r=-0.635,-0.563,P＜0.05).ConclusionsSerum CysC and urinary MA are sensitive indexes of early renal function injury in patients with hypertension.The combined determination of serum CysC and urinary MA can improve the detection rate of early renal function injury.

Objective To discuss the clinical aesthetic effect of vermilion repair on cleft lips after using double-line reconstruction.Methods 68 children with cleft lip were repaired according to the principle of double-line reconstruction,and two contents including 7 projects,such as shapes of upper lips,vermilion borders of lips,vermilion shapes and lips,etc,were evaluated comprehensively within one month after operation for assessing the postoperative effect.Results 68 cases were followed up,with the follow-up rate of 100％,and 62 cases (91.2％) were satisfied with the vermilion repair.Six cases (8.8％) had a common effect of vermilion shapes after repair.In the 7 contents evaluated,satisfactory results were achieved in the projects except the relatively poor symmetry vermilion borders of lips.Conclusions The double-line reconstruction helps to improve the aesthetic effect of vermilion repair on cleft lips.

Objective To investigate the influence of continuous veno-venous hemofiltration (CVVH) on cardiac output (CO) value and parameters of hemodynamics monitored by transpulmonary thermodilution technique in critical patients. Methods A prospective cohort study was conduced. Sixty-two critical patients admitted to intensive care unit (ICU) of Zunyi Medical College Affiliated Hospital from January 2011 to October 2015 were enrolled. All of the patients received CVVH through femoral vein puncture catheter. The CO value was monitored before CVVH operation, immediately after CVVH operation (8 ℃ normal saline was injected immediately after the output of blood from the arterial end), 5 minutes after operation, the time at the sudden interruption (press pause key after 10 minutes of operation) and resumed immediately, 15 minutes and 30 minutes after operation by pulse-indicated continuous cardiac output (PiCCO) with transpulmonary thermodilution method. The changes in heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), and blood temperature were observed at all time points. Results From CVVH before start to 5 minutes thereafter, CO values were not significantly changed in patients, fluctuating in 6.96 (7.33, 8.67)-6.98 (6.43, 7.45) L/min. When CVVH was suddenly interrupted, CO value was immediately increased to the peak 8.04 (7.36, 8.77) L/min, which showed statistically significant difference as compared with other time points (all P < 0.01). Immediately after the CVVH recovery from interruption, the CO value dropped to 4.71 (4.14, 7.26) L/min, and it was significantly lower than those at other time points (all P < 0.01). With the CVVH recovery, the patients' CO value was gradually restored to the stable operation ahead of interruption [4.71 (4.14, 7.26)-6.85 (6.08, 7.26) L/min]. During CO monitoring, HR, MAP, CVP and blood temperature of the patients were at the same level, and no significant changes were founded. Conclusions CVVH interruption of immediate PiCCO monitoring CO value were significantly increased, immediately after the CVVH recovery the CO value were significantly reduced, and the normal operation of CVVH did not affect the CO value monitoring. Hemodynamics and blood temperature of all patients were stable during CVVH.
