Pancreatic cancer is a highly malignancy of the digestive system, with low early diagnosis rate and poor prognosis. Cancer cachexia, muscle and adipose tissue wasting are important factors affecting surgical complications and long-term prognosis of patients with pancreatic cancer. On one hand, the occurrence and development of pancreatic cancer cachexia are associated with the decrease of food intake. On the other hand, the characteristic of tumor hypermetabolism, many inflammatory factors, fat and protein regulatory factors and many neuroendocrine pathways are also involved in pancreatic cancer cachexia. At present, the understanding of cancer cachexia and tissue wasting is not comprehensive, and the diagnostic methods are not unified. The main screening method is based on body mass index, but it is not applicable to obese patients. The detection of serum cytokines and determination of intramuscular fat content based on the abdominal computed tomography scan also play pivotal roles in the diagnosis of pancreatic cancer cachexia. Perioperative inhibition of tissue wasting can not only reduce surgical complications, but also improve the prognosis of pancreatic cancer patients. However, there is no effective method to completely reverse cancer cachexia. Multidisciplinary treatment is the routine therapy. Surgical treatment to remove the tumor is the fundamental measure to impede the development of cachexia. In addition, strengthening nutritional support, reducing inflammation and stress reaction, reducing the muscle wasting are also important in the treatment of cachexia during the perioperative period. Combined with self experience, the authors comprehensively analyze research advances, summarize the etiology, molecular mechanism, diagnosis and treatment of tissue wasting, in order to investigate tissue wasting and perioperative treatment strategies of pancreatic cancer patients.

Objective To investigate the effect of liver cirrhosis on the potency of propofol for sedation in rats. Methods Fifty-eight male SD rats, aged 10-12 weeks, weighing 180-220 g, were randomly divided into 3 groups: control group (group C, n = 18), mild liver cirrhosis group (group M1, n =20) and severe liver cirrhosis group (group M2, n = 20). The model of liver cirrhosis was established using four factors described by Chen et al. After successful establishment of the model, propofol was injected intravenously. The dose of propofol was determined by up-and-down sequential method for loss of righting reflex. The dose of propofol was 5.912 mg/kg in the first rat and the ratio of the doses between the two consecutive rats was 0.85. ED50 of propofol was calculated using up-and-down sequential method. Results ED50 of propofol was significantly lower in group M1 and M2 than in group C and in group M2 than in group M1 ( P < 0.05 or 0.01 ). Conclusion The liver cirrhosis can enhance the potency of propofol for sedation in rats.

Objective To investigate the effects of remifentanil on lipid peroxidation druing hemorrhagic shock-induced acute lung injury (ALI) in rabbits. Methods Thirty-two healthy adult rabbits weighing 2.0-2.5 kg were randomly divided into 4 groups (n = 8 each): sham operation group (group S); ALI group; low-dose remifentanil group (group LR); high-dose remifentanil group (group HR). The left femoral artery was cannulated for blood-letting and blood sampling. The right femoral artery was cannulated for remifentanil administration. The model of hemorrhagic shock was established by modified Wigger' s methods. In group S, only cannulation was performed. In group LR and HR, remifentanil was infused intraperitoneally at 0.66 and 1.32 μg·kg-1 ·min-1 15 min before blood-letting respectively, while group ALI received equal volume of normal saline instead. Arterial blood samples were taken at 0, 20,70 and 100 min after blood-letting (T1-4) for blood gas analysis. The animals were then sacrificed and the lungs were immediately removed for histological examination with light microscope and determination of W/D lung weight ratio, MDA content and SOD activity. Results W/D ratio and MDA content were significantly increased, while SOD activity was significantly decreased in group ALI compared with group S (P <0.05). The pH value at T2 and PaO2 at T2-4 in group LR and the pH value and PaCO2 at T2-4 in group HR were significantly higher than those in group ALI (P < 0.05). W/D ratio and MDA content were significantly lower,while SOD activity was significantly higher in group LR and HR than in group ALI, and in group HR than in group LR (P < 0.05). Remifentanil infusion significantly attenuated the pathologic changes in a dose-dependent manner. Conclusion Remifentanil pretreatment can attenuate hemorrhagic shock-induced ALI through inhibiting lipid peroxidation in rabbits.

OBJECTIVETo investigate the regulation of leptin on insulin secretion and expression of ATP-sensitive potassium channel subunit sulfonulurea receptor 1 (SUR1) mRNA, and to determine whether the effects of leptin are mediated through known intracellular signaling transduction.
METHODSPancreatic islets were isolated by the collagenase method from male SD rats. The purified islets were incubated with different concentrations of leptin for 2 h in the presence of different concentrations of glucose. Insulin release was measured using radioimmunoassay. Expression of SUR1 mRNA was detected by RT-PCR.
RESULTSIn the presence of leptin 2 nmol/L, insulin release was significantly inhibited at either 11.1 or 16.7 mmol/L glucose concentration (both P < 0.05), but insulin release was not altered at glucose of 5.6 mmol/L physiological concentration. The dose-response experiment showed that the maximal effect of leptin on insulin secretion achieved at 2 nmol/L. Exposure of islets to 2 nmol/L leptin induced a significant increase of SUR1 transcription levels by 71% (P < 0.01) at 11.1 mmol/L glucose and by 56% (P < 0.05) at 16.7 mmol/L glucose concentration. Selective phosphatidylinositol 3-kinase (PI 3-kinase) inhibitor wortmannin significantly prevented the leptin effect on insulin secretion and SUR1 mRNA expression.
CONCLUSIONSRegulatory effects of leptin on insulin secretion could be biphasic at different concentrations of glucose and leptin. The stimulatory regulation of SUR1 transcription levels may be mediated through activation of PI 3-kinase pathway, which may be a possible mechanism of leptin in regulating insulin secretion.

Objective To investigate the exposure to stroke risk factors, the proportion of high?risk individuals, and the relationship between risk factor exposure and impaired cerebrovascular hemodynamics in patients at Pu'er People's Hospital. Methods Between April 2014 and June 2017, this study enrolled inpatients and outpatients of the neurology department of Pu'er People's Hospital who underwent cerebrovascular hemodynamic examinations to evaluate stroke risk. A total of 30 103 (12 793 males and 17 310 females) participants aged 22 to 99 (53.3±14.5) years were included. The distribution of exposure rates for stroke risk factors and proportion of high?risk individuals were determined according to age and sex. The relationships between integral scores of cerebrovascular hemodynamics and exposure to risk factors were also analyzed. Results Exposure rates for risk factors of hypertension, dyslipidemia, diabetes, heart disease, stroke family history, cigarette smoking, alcohol drinking, and overweight or obesity in males were 36.6%, 11.4%, 8.8%, 5.9%, 7.0%, 41.6%, 37.8%, and 51.4%, respectively. The exposure rates in females were 31.2%, 11.3%, 7.6%, 5.5%, 6.8%, 0.7%, 1.6%, and 48.8%, respectively. Differences between age groups for all risk factors were significant (P<0.01). Exposure rates for hypertension, diabetes, cigarette smoking, alcohol drinking, and overweight or obesity in males were significantly higher than in females (P<0.01). High?risk males and females accounted for 41.8% and 35.6% (χ2=119.82, P<0.01) and the rates in both groups increased significantly with age (χ2=1 838.2, 2 881.5, P<0.01). Risk factors including age, hypertension, dyslipidemia, diabetes, heart disease, stroke family history, alcohol drinking, and body mass index were independent predictors of increased individual risk of stroke. Conclusions Exposure levels for stroke risk factors and the proportion of individuals at high risk of stroke were relatively high in the hospital population. Cerebrovascular dysfunction is closely related to exposure to common risk factors for stroke.
