ObjectiveTo investigate the feasibility and effectiveness of low central venous pressure (LCVP) in the operation of major hepatic resection.MethodsFourty-eight patients underwent major hepatic resection were randomized into two groups: LCVP and control group.In the LCVP group,CVP was maintained ≤5 cm H2O during the hepatic resection and then returned to normal after resection.In the control group,CVP was maintained normal between 6 -12 cm H20.The duration of hepatectomy,volume of blood loss,volume of blood transfused and renal function were compared between the two groups.ResultsFor the LCVP and control group,the time for hepatectomy was (45 ± 8 ) and ( 35 ± 5 ) min,respectively; the volumes of blood loss were ( 850 ± 160) and (436 ±280)ml,respectively; the blood loss during operation was (490 ± 130) and (270 ± 105 ) ml respectively.The differences were statistically significant (t values were 15.53,7.69 and 17.89 separately,P <0.05 ).No significant difference in the renal function was observed before and after the operation ( P > 0.05 ).Conclusion Using LCVP technique during liver resection significantly reduced the operation time,blood loss and blood infusion.And there wa.s no obvious adverse effect on renal function.

Objective To investigate and evaluate the changes of PYK2 expression in hippocampal neurons and microglial cells in Kainate acid-induced status epilepticus. Methods Kainate acid-induced status epilepticus was established in rats, and by using immunostaining, changes of PYK2 expression in hippocampal neurons and microglial cells was investigated. Results Expression of PYK2 in hippocampal pyramidal neurons was markedly decreased after kainate acid-induced status epilepticus. However, 24h after the epileptic onset, a pronounced up-regulation of PYK2 and phosphor-PYK2 immunoreactivities were evident in amoeboid microglial cells. The upregulation of PYK2 and phosphor-PYK2 was in accordance with the morphological changes of the activated microglial cells. Conclusion PYK2 was activated in microglial cells after seizure. Furthermore, the activation of PYK2 in microglial cells after seizure might be related to the morphological and behavioral changes of microglial cells after activation.

Objective To investigate and evaluate the changes of phospho PYK2 and phospho p38MAPK expression in neurons after focal cerebral ischemia. Methods Focal ischemia reperfusion model was established in rats, and by using immunostaining, the changes of phospho PYK2 and phospho p38MAPK expression in neurons was observed. Results Faint phospho PYK2 and phospho p38MAPK immunoreactivity were revealed in normal cortical neurons. Fifteen minutes after the ischemia onset, a pronounced upregulation of phospho PYK2 and phospho p38MAPK immunoreactivities were evident in these ischemia attacked neurons. The immunoreactivities of phospho PYK2 and phospho p38MAPK reached its peak at 30min after ischemia, and decreased 60min after ischemia. Conclusion Cerebral ischemia was able to induce neuronal PYK2 phosphorylation. The activation of PYK2 might link ischemia attack to the p38MAPK signaling pathway to initiate the neuronal response to the stress stimuli

Chongqing Medicine 2017;46(16):2224-2227,2232
Objective To study the relationship between smoking and the incidence of pulmonary tuberculosis(TB) in Chinese people.Methods The Pubmed database and three Chinese databases such as Wanfang Data,Veipu data(VIP) and China national knowledge infrastructure database (CNKI) were retrieved.The literatures on the relationship between smoking and pulmonary TB incidence in Chinese people published before April 2016 were analyzed.Results Fifteen studies were included,after excluding 1 low quality study,the rest had no statistical heterogeneity.The merged odd ratio (OR) was 1.71,95 % confidence interval (CI) 1.51-1.90.Two studies observed the relationship between the amount of cigarettes and TB pathogenesis,but there was heterogeneity and could not be further merged the OR value for conducting analysis.No subgroup analysis of gender was performed in all studies.Conclusion The risk suffering from pulmonary TB in Chinese smokers is 1.71 fold of non-smokers,and smoking increases the risk of pulmonary TB onset.

Expression of apelin mRNA in the isolated mouse adipocytes was confirmed by Northern blot. The level of apelin mRNA increased during stage of differentiation of 3T3-L1 cells. Insulin up-regulated the apelin expression in 3T3-L1 adipocytes, suggesting that apelin expression in adipocyte may correlate with obesity, insulin resistance and hypertension.

Resistance is one of the most important reasons that restrict the clinical application of most chemotherapeutic medicines. Docetaxel is a very widely applicated antitumor medicine. Most of the researches on the mechanism of resistance against docetaxel focused on the drug transporters, changes in drug metabolism and pathway alteration of cell cycle and apoptnsis. The mechanism of docetaxel resistance and the predictive data based on clinical research to docetaxel therapy in cancer treatment were reviewed.

Objective To discuss the value of 256 spiral CT dynamic volume scanning in the diagnosis of moyamoya disease.Methods Twenty-three patients with moyamoya disease undergoing 256 spiral CT dynamic volume scanning (moyamoya group) were selected,and 18 patients having cerebrovascular disease symptoms,but the brain artery without stenosis (control group) were also selected.The volume reconstruction (VR),maximum intensity projection (MIP) and cerebral CT perfusion imaging was displayed.The cerebral CT perfusion imaging parameters of anterior,middle,posterior cerebral artery were measured and analyzed.Results VR,MIP could well reproduce lesion location,degree of stenosis and skull base abnormal vascular network change.Compared with control group,the cerebral blood volume (CBV) was increased [(8.46 ±0.91) ml/100 g vs.(2.92 ±0.72) ml/100 g],time to peak (TTP) was increased [(30.27 ±5.02) s vs.(24.83 ±4.07) s] in anterior cerebral artery,and there was significant difference (P < 0.01),but there was no significant difference in the cerebral blood flow (CBF),the mean transit time (MTT)(P > 0.05).Compared with control group,CBV was increased [(8.06 ± 1.05) ml/100 g vs.(6.08 ± 0.56) ml/100 g],MTT,TTP was increased [(6.34 ± 1.01) s vs.(3.83 ± 0.83) s,(32.06 ± 2.55) s vs.(25.83 ± 2.34) s] in middle cerebral artery,and there was significant difference (P< 0.01),but there was no significant difference in CBF (P > 0.05).Compared with control group,there was no significant difference in the cerebral CT perfusion imaging parameters of posterior cerebral artery (P >0.05).Conclusion 256 spiral CT dynamic volume scanning can be combined with morphology and function imagings,and has important guiding significance for diagnosis of moyamoya disease.
