Objective To investigate the relationship between changes in Ca2+ concentration and unit discharge in the hippocampal neurons of epileptic rats.Methods Thirty-six healthy male Wistar rats were divided into three groups. Rats of the epilepsy group received an intraperitoneal injection of benzylpenicllin sodium at 6 million unit/kg; Rats of the epilepsy pretreatment group received 20 mg/kg of flunarizine at 14 and 2 hours before injection of benzylponicllin;the control group of rats received an intraperitoneal injection of normal saline.Three groups of rats were euthanized after recording of the unit discharge,and bilateral hippocampal cells were obtained to measure the cellular concentration of Ca2+ fluorescence using the new generation Ca2+ fluorescent dye Fluo-3-AM and flow cytometry.Results (1) A total of 24 units of hippocampal discharges were recorded in the control group.The average concentration Ca2+ fluorescence of the hippocampal neurons was 37.12±5.08.(2)A total of 78 units of hippocampal discharges were recorded in the epilepsy group.The average concentration of Ca2+fluorescence of the hippocampal neurons was 52.04±6.75.(3)A total of 47 units of hippocampal discharges were recorded in the epilepsy pretreatment group. The average concentration of Ca2+ fluorescence of the hippocampal neurons was 37.79±3.09.The correlation coefficient between the average concentration of Ca2+ fluorescence of the hippocampal neurons and the number of units of hippocampal discharge ( r=0.737,P<0.01).Conclusion There is a positive correlation between changes in average concentration of Ca2+ fluorescence of the hippocampal neurons and the numbers of units of hippocampal discharge.

Neutrophils play a critical role in ventilation-induced lung injury. This study was aimed to investigate the characteristics of neutrophils influx in lungs induced by high tidal volume ventilation. Anaesthetized rats were randomly divided into low tidal volume ventilation group (Vt: 7 mL/kg, LV group) or high tidal volume ventilation group (Vt: 42 mL/kg, HV group) (n=40 in each). Rats in each group were ventilated for 0, 60, 90, 120 and 240 min. The wet/dry lung weight ratio (W/D) was measured. The levels of macrophage inflammatory protein-2 (MIP-2) and tumor necrosis factor-α (TNF-α), and the activity of myeloperoxidase (MPO) were detected by enzyme-linked immunosorbent assay (ELISA). The number of neutrophils in bronchoalveolar lavage fluid (BALF) was counted after Wright's staining, and the percentage of netrophils in lung tissues calculated. Histopatholgical examination was used to observe the changes of lung tissues after different ventilations. The results showed that the W/D weight ratio was increased, and the levels of MIP-2 and TNF-α significantly enhanced in HV group at 90, 120 and 240 min. Neutrophils in BALF and the neutrophil percentage in lung tissues were also elevated at 120 and 240 min, which coincided with the enhanced activity of MPO in HV group. The lung injury was significantly related with the ventilation time and the infiltration of neutrophils in lungs in HV group. In conclusion, in ventilation-induced lung injury, neutrophil infiltration is present in a time-dependent manner and associated with the aggravated lung injury. Pulmonary structural damage may be the main reason for ventilation-induced lung injury.

ObjectiveTo investigate the effect of patient-controlled epidural analgesia(PCEA) with opioids on serous myelin basic protein(MBP) and somatosensory evoked potential(SEP) of lower limbs in puerperants.MethodsA total of 120 puerperants,after receiving cesarean section,were divided into four groups by random number table method as group B,BR,MR and R randomly,and each group included 30 cases.After surgery,each case received PCEA:group B received 0.008% butrophanol;group BR received 0.008% butrophanol + 0.2% ropivacaine;group MR received 0.004% morphine +0.2% ropivacaine and group R received 0.2% ropivacaine only.VAS score,OAA/S score,adverse effect occurrence,concentration changes of serous MBP,SEP of both lower limbs and neurological function were observed at 2h(T1 ),4h(T2),8 h(T3),12h(T4),24 h(T5) and 48h (T6) after surgery.ResultsVASscoresofgroupBR(1.64±0.38,1.86±0.62,1.93±0.67) and MR( 1.74 ±0.39,1.91±0.58,1.98 ±0.63) at T3,T4,T5 were lower than those of group B(4.6 ±0.5,4.6 ±0.3,4.7 ±0.3)and R(2.64 ±0.41,2.83 ±0.91,3.37 ±0.87) (P<0.05).There was no significance in four groups in OAA/S score at each point (P > 0.05 ).Incidence of nausea ( 6 cases),vomiting ( 2 cases) and abdominal distention ( 5cases) of group M was higher than that of other three groups(P<0.05).There was no significant difference in concentrations of serous MBP,SEP and neurological function in all four groups between preoperative time and 48h after operation(P>0.05).ConclusionLower-dose and lower- concentration opioids used for PCEA have no influence on serum MBP and SEP.

Objective To investigate the clinical application of Glissonean pedicle transection method in hepatocellular carcinoma. Methods We analyzed the clinical data of 232 cases of hepatocellular carcinoma underwent hepatic resection in our department from April 2009 to April 2013. Eighty-nine cases underwent hepatic resection by Glissonean pedicle transection method, and 143 cases underwent Pringle maneuver. Results There was no significant differences in the operation time and blood loss between the two groups (P > 0.05). However, the postoperative hospital stay time and the postoperative complications in group A were better than those in group B(P<0.05). Levels of ALT and AST in group A increased significantly slowly than those in group B. The 1, 3-year disease-free survival rates in the two groups were 87.4%, 71.1% and 85.1%, 60.0%, respectively. The 1, 3-year survival rates were 93.3%, 73.5% and 93.4%, 65.0%, respectively, with no significant differences (P>0.05). Conclusion Glissonean pedicle transection method has many advantages including effectively preventing the intraoperative bleeding, maximally reserving the remaining of liver function, decreasing the rate of tumor spread and metastasis. Meanwhile, it is a safe and effective technique for hepatectomy without dissection of the hepatic artery, portal vein and bile duct in the hepatoduodenal ligament.

Objective To detect the positive rates of antibodies against avian influenza virus (AIV) subtypes H5, H6, H7 and H9 among people in poultry occupations in Guangdong province and to analyze the transmission of various subtypes of AIV from poultry to human contacts for the prevention and control of novel AIV infection in human beings.Methods Serum specimens were collected from 1066 peo-ple in poultry occupations ( occupational group) and 205 people not in poultry occupations ( non-occupational group) in 10 cities of Guangdong province.The inactivated AIV strains, isolated from poultry or environment of Guangdong province, were used as antigens to detect antibodies against AIV subtypes H5, H6, H7 and H9 by using the hemagglutination inhibition ( HI) assay.Results The positive rates of antibodies against AIV subtypes H5, H6, H7 and H9 carried by people from the occupational group were respectively 0.44%, 0%, 0.30%and 0.30%in 2013 and 1.08%, 0.0%, 0.0%and 0.27%in 2014.Only the anti-H9 anti-bodies were detected in serum samples collected form people in the non-occupational group in 2013 with a positive rate of 0.95%.No significant differences with the positive rates of anti-AIV antibodies were found between the occupational group and the non-occupational group.However, the geometric mean titer ( GMT) of anti-AVI antibodies in people from the occupational group was higher than that of the non-occupational group.Conclusion Although a grand spread of AIV from avian to human is not likely to happen yet, con-tacting with poultry is the risk factor for AIV infection in Guangdong population.A long-term surveillance of anti-AIV antibodies in serum should be strengthened among people in poultry occupations for the timely pre-vention and control of novel AIV outbreak.
