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.

Objective To evaluate the role of combination of three-vessel views in ultrasound diagnosis of fetal aortic arch and pulmonary arterial branch anomalies.Methods The data of 66 cases of fetal aortic arch and pulmonary arterial branch anomalies were retrospectively analysed,including echocardiographic data,autopsy and operation records and postnatal follow-up results.Echocardiogaphic features and display frequencies on three vessels and trachea view(3VT),three vessels view(3VV)and three vessels and pulmonary arterial branches view(3VP)were summarized.Results There were 52 cases of aortic arch abnormalities,including 32 cases of right aortic arch with left ductus arteriosus,4 cases of double aortic arch,7 cases of aberrant right subclavian artery,6 cases of coarctation of aorta and 3 cases of interruption of aortic arch.Fourteen cases were diagnosed pulmonary aterial branch abnormalities,including 1 0 cases of crossed pulmonary arteries,2 cases of anomalous origin of left pulmonary artery from aortic arch and 2 cases of pulmonary artery sling.The display frequencies of fetal aortic arch and pulmonary arterial branch anomalies on 3VT,3VV and 3VP were 80.3%,19.7% and 39.4%.Conclusions The combination of three-vessel views is of great value in prenatal diagnosis of fetal aortic arch and pulmonary arterial branch anomalies.

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.

0.05). There was no significant difference in radiation reaction and squeal between two groups. Conclusions The clinical results of LCAH radiotherapy may be improve the three year of local control rate than conventional CF in stage Ⅲ~Ⅳa but do not improve the survival rate of three years.The radiation reaction and sequela was similar,is worth further study.

Objective To evaluate the clinical significance of combined serum tumor markers assay in patients with gastric or colorectal carcinoma. Methods Serum level of 12 common tumor markers, including CA19-9,NSE,CEA,CA242 Jerritin,Beta-HCG,AFP,free-PSA,PSA,CA125,HGH and CA153, was measured with multi-tumor markers protein biochip detective system in 179 cases of gastric and colorectal carcinoma, 82 patients with benign digestive disease and 160 healthy volunteers. Results Cancer patients had significantly higher positive rates than that of two other controls (P

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 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 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

In recent years, the number of guidelines/consensus in the field of dermatology has increased in China, but the quality is variable. This article proposes to describe the specific process of guideline/consensus development in 10 steps, focusing on the initiation phase, advancement phase, as well as dissemination, implementation and update phases, with the aim to improve the quality of guidelines/consensus in the field of dermatology.
