Objective To investigate the change of homocysteine (Hcy),high sensitive C-reactive protein (hs-CRP)and Inter-leukin 6 (IL-6)in patients with Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS)complicated by Cerebral Infarction (CI).Methods Chose 55 patients with OSAHS and 56 patients with CI.All patients with OSAHS were divided into mild group,moderate group and severe group by polysomnography,and all patients were divided into simple OSAHS group,sim-ple CI group and OSAHS complicated by CI group.All the patients’sleep apnea hypoventilation index (AHI),the lowest oxygen saturation (LSpO2 ),average blood oxygen saturation (MSpO2 ),sleep apnea the longest (LAT)and the level of Hcy,hs-CRP,IL-6 were determined,and compared with 30 cases of control group.Results The AHI,LAT,Hcy,hs-CRP and IL-6 of simple OSAHS group and simple CI group were obviously higher than that in control group,LSpO2 ,MSpO2 were obviously lower,the differences were statistical significant (P<0.05).The AHI,LAT,Hcy,hs-CRP and IL-6 of OS-AHS complicated by CI group were obviously higher than that in simple groups,but LSpO2 and MSpO2 were obviously low-er,and the differences were statistical significant (P<0.05).With the aggravation of OSAHS,Hcy,hs-CRP and IL-6 were gradually increased.Hcy,hs-CRP and IL-6 were positively correlated with AHI in patients with OSAHS,correlation coeffi-cient were 0.751,0.678 and 0.635,respectively (P<0.001).Conclusion OSAHS was closely related to the occurrence and development of CI,the dynamic monitoring of Hcy,hs-CRP and IL-6 levels has a certain reference value for evaluation of therapeutic effect.

Pancreaticoduodenectomy (PD) is the mainstay of treatment for periampullary space-occupying disease. The occurrence of pancreatic fistula after PD is still an unsolved clinical problem, which seriously affects the safety of surgery. Various methods have been reported in clinical practice to reduce the incidence of pancreatic fistula, such as improving pancreaticoenteric anastomosis, using biological sealants, applying somatostatin analogs, and continuous peritoneal irrigation, etc., but the incidence of pancreatic fistula remains at 5%-30%. There are many risk factors related to pancreatic fistula after PD, in which reasonable selection of suture materials is an important factor and also an important factor affecting the curative effect of surgery. The authors analyze the characteristics and shortcomings of various sutures used in PD, in order to provide help to improve the safety of surgery and reduce the incidence of pancreatic fistula after PD.

Objective To observe the effects of naringin (Nar) on hemodynamics in myocardial ischemia-reperfusion(MI/R) injury rats for investigating its protective role on MI/R rats.Methods The ischemia-reperfusion(I/R) model was prepared by ligating the left anterior descending coronary artery,meanwhile different doses of Nar(10,20,40 mg/kg) were given.Then the electrocardiogram (ECG) was recorded after 7 d.The left ventricular end diastolic pressure (LVEDP),left ventricular systolic pressure (LVSP) and maximum ascending rate of left ventricular pressure/maximal descending rate of left ventricular pressure (±dp/dtmax) were measured.The activities of srum creatine kinase (CK) and lactate dehydrogenase (LDH) were measured by using the chemical colorimetry method.Results Compared with the MI/R group,Nar 20,40 mg/kg could decrease LVEDP,increased ±dp/ dtmax and LVSP,and decreased the activities of serum CK and LDH (P＜0.05),showing a dose-dependent manner.Conclusion Nar has the protective effect against MI/R injury rat and alleviates the myocardial damage extent,which may be related with improving the hemodynamics.
