Postoperative ileus is commonly referred to the inhibition of gastrointestinal motility after ab-dominal surgery. Some causes are responsible for the ileus, including postoperative pain and electrolyte im-balances, and manipulations during surgery. Although gastrointestinal motility normalizes spontaneously in most patients, some develop severe to postoperative ileus, which is difficult to treat, with a delayed recovery from surgery, prolonged hospital stay, and increased treatment costs. So, it is essential to understand the mechanisms of postoperative ileus for effective prevention and treatment.

0.05). There was no significant difference in radiation reaction and squeal between two groups.

OBJECTIVE To analyze the status of concomitant or combined infection in patients presented with hepatitis B for investigation of the nosocomial infection control. METHODS We determined the serum virus marker of hepatitis A,C,D,E and G from 786 cases infected with hepatitis B virus. RESULTS Double and multiple infections accompanied by hepatitis B were found to be 16.67%(131/786) and 1.78%(14/786),respectively,especially with hepatitis C which amounted to 45.52%(66/145) of those with concomitant infections(double or multiple). CONCLUSIONS It is commonness that the patient of hepatitis B to preexist other kinds of hepatitis virus infections.We determine other hepatitis markers in patients of hepatitis B to be probative for nosocomial infection.

This article was aimed to study the main effective substances and characteristics of Ke-Luo-Xin (KLX) capsule. HPLC-DAD system was applied in the establishment of HPLC finger prints of serum of rats after taking KLX capsule. And then, serum samples taken KLX capsule, blank blood serum, and single crude drugs were com-pared. Constituents absorbed into the serum were determined by HPLC-DAD system. The results showed that meth-ods for serum HPLC fingerprinting had good precision, reproducibility and stability. A total of 13 constituents migrat-ing to the blood were detected, of which 9 were prototype constituents, 4 were metabolites. Prototype constituents in-cluded aloeemodin and chrysophanic acid. It was concluded that 13 constituents migrating to the blood may be the main effective substances of KLX capsule.

Objective To investigate the synergic ratio of sorafenib (SO) and sulforaphane (SF) against the hepatocellu‐lar carcinoma cell line HepG2 in vitro .Methods The synergic effect of SO combined with SF against HepG2 cells was deter‐mined by the CCK8 assay (the synergic effect was determined by combination index (CI) value:CI>1 .1 ,antagonistic;0 .91 .1) ,whereas 20∶1 ,5∶1 and 1∶5 ratio resul‐ted in synergistic activity (CI<0 .9) .Furthermore ,10∶1 ratio acted as an additive effective (0 .9

Objective To evaluate the effect of penehyclidine hydrochloride on hyperoxia-induced acute lung injury and the relationship with endoplasmic reticulum stress-dependent apoptosis in infantile rats.Methods Ninety-six clean-grade male infantile Sprague-Dawley rats,weighing 40-50 g,aged 14 days,were allocated into 4 groups (n =24 each) using a random number table method:control group (C group),penehyclidine hydrochloride group (P group),hyperoxia group (HO group) and hyperoxia plus penehyclidine hydrochloride group (HP group).Infantile rats were intravenously injected with penehyclidine hydrochloride (0.3 mg/kg) at the same time point every day for 3 consecutive days in P and HP groups.Infantile rats were injected with the equal volume of normal saline instead of penehyclidine hydrochloride in C and H groups.Acute lung injury was induced by inhaling oxygen at concentration greater than 90％ for 72 h starting from 4th day after administration.Infantile rats were sacrificed at the end of inhaling,and lungs were removed for examination of the pathological changes and for determination of weight to dry weight ratio (W/D ratio),index of quantitative evaluation for alveolar damage (IQA),pneumonocyte apoptosis (using TUNEL),expression of glucose-regulated protein 78 (GRP78) and CCAAT/enhancer-binding protein homologous protein (CHOP) protein and mRNA in lung tissues (by Western blot or using reverse transcription-polymerase chain reaction).The mitochondrial injury score was assessed,and apoptotic index (AI) was determined.Results Compared with C group,the W/D ratio,IQA,AI and mitochondrial injury score were significantly increased,and the expression of GRP78 and CHOP protein and mRNA was up-regulated in HO and HP groups (P＜0.05),and no significant change was found in the parameters mentioned above in group P (P＞0.05).Compared with HO group,the W/D ratio,IQA,AI and mitochondrial injury score were significantly decreased,the expression of GRP78 and CHOP protein and mRNA was downregulated (P ＜ 0.05),and the pathological changes of lung tissues were significantly attenuated in HP group.Conclusion Penehyclidine hydrochloride can mitigate hyperoxia-induced acute lung injury,and the mechanism may be related to inhibiting endoplasmic reticulum stress-dependent apoptosis in infantile rats.

Objective:To explore the application effects of standardized patient (SP) and breast visual palpation simulation system on clinical probation of breast surgery for medical students.Methods:A total of 110 students were randomly divided into experimental group and control group, and each group was further divided into 5 subgroups. In the experimental group, SP scripts of five common diseases in breast surgery department were designed according to the syllabus before probation, and the teachers were trained. During the probation, we first talked about the characteristics of disease diagnosis and treatment, and then the five subgroups collected the history of the disease according to the SP of different diseases mentioned above, and checked the corresponding lesions on the breast visual palpation simulation system. In the physical examination, SP responded to the students' questions. The control group also talked about the above-mentioned five diseases during the probation, and then the five subgroups carried out history collection and physical examination for specific patients in the hospital. Finally, the teaching effects were analyzed through medical record writing, theoretical examination, physical examination and student evaluation. SPSS 26.0 was used for chi-square test (or Fisher exact test) and Mann-Whitney U test. Results:There was no significant difference in the theoretical examination between the two groups. It was demonstrated that the correct rate of experimental group was significantly higher than that of the control group in medical history collection, especially in the main symptoms, incentives, aggravation and remission factors, accompanying and differential symptoms and so on. And the positive results of breast, nipple and axillary lymph node palpation in the experimental group were significantly higher than those in the control group through the physical examination operation of breast visual palpation simulation system. The analysis of students' evaluation showed that the teaching efficiency of the experimental group increased, and the students' satisfaction was improved (satisfaction rate: 92.73% vs. 76.36%).Conclusion:The application of SP and breast visual palpation simulation system in breast surgery probation teaching can not only protect the privacy of clinical patients, but also improve the teaching effects, which can be popularized in the clinical teaching of breast surgery.
