To study the immunopathological characteristics and differential diagnosis of hepatic angiomyolipoma(AML).Methods:Thirty-six surgically resected hepatic AML were investigated clinicopathologically and immunohistochemically with 10 antibodies.Results:Hepatic AML occurred in 21 females and 15 males,with the mean age of 41.6 years(26-60 years old).The patients with AML often had no special symptoms even had large space-occupying lesions in the liver.The diameter of AML was 2.5 cm to 14 cm(mean 6.8 cm).Histologically,AML was composed of varying heterogeneous mixture of 3 tissue components:blood vessels,smooth muscle and adipose cells.Extramedullary hemopoiesis sometimes existed.According to tissue components,AML was subcategorized into mixed type(19.4%,n=7),lipomatous type(11.1%,n=4),myomatous type(66.7%,n=24),and angiomatous type(2.8%,n=1).The epithelioid smooth muscle cells were sensitive to HMB-45(100%),SMA(100%),and CD117(66.7%) staining.Conclusion:Hepatic AML often contains smooth muscle elements,which have varied morphological features and should be carefully differentiated from hepatocellular carcinoma,mesenchymal hamartoma，and tumors with rich fat or blood vessels.Immunohistochemical staining with HMB-45 and SMA are the best available markers for the diagnosis of hepatic AML.

Objective To investigate the effect of bilateral sacrospinous ligament fixation by Pavlik harness method in the treatment of pelvic organ prolapse (POP). Methods Sixty patients with POP received operation were divided into bilateral sacrospinous ligament fixation by Pavlik harness method group (study group,30 cases),posterior intravaginal sling plasty group (P-IVS group, 15 cases) and sacrospinous ligament fixation group (SSLF group, 15 cases) by random digits table. The data of the three groups, such as operation time, bleeding during the operation, indwelling urinary catheter time, duration out of bed after operation, cure rate, recurrence rate and the quality of sexual life were observed. Results The operation time in study group [( 30.5 ± 5.3 ) min] was significantly shorter than that in SSLF group [(43.5 ± 10.6) min](P ＜ 0.05 ), and the duration out of bed in study group [( 1.5 ± 0.6) d] was earlier than that in SSLF group [(3.1 ±0.7) d] and P-IVS group [(3.3 ±0.8) d](P＜0.05). The POP-Q stage of all the patients being hospital was 0 or Ⅰ , approached the cure standard. Patients were followed up for 3-16 months after operation, the recurrence rate and the decrease of the quality of sexual life in study group [0,3.3%(1/30)]were lower than those in P-IVS group [20.0%(3/15),13.3%(2/15)] and SSLF group[6.7%(1/15),26.7%(4/15)] (P ＜ 0.05). Conclusion Bilateral sacrospinous ligament fixation by Pavlik harness method is a simple, firm operation, and the position of vagina does not axialitily change and suits the anatomy, so it is effective and worth spreading clinically to treat the POP.

Gastric cancer is one of the common malignant tumors in digestive system. The incidence of gastric cancer in China is higher than that in developed countries. The prognosis of gastric cancer is closely related to the stage of cancer, and the prognosis of advanced gastric cancer is poor. Improving the detection rate of early gastric cancer is the key to improve the survival of patients with gastric cancer. Endoscopic technology developed rapidly in recent years,various forms of endoscopy have been applied in clinical practice,and the detection rate of early gastric cancer was increased. This article reviewed the advances in study on endoscopic diagnosis of early gastric cancer.

Objective To investigate the efficacy of postoperative concurrent chemoradiotherapy for early-stage cervical adenosquamous carcinoma and adenocarcinoma.Methods A total of 62 patients with cervical adenosquamous carcinoma,149 patients with cervical adenocarcinoma,and 2687 patients with cervical squamous cell carcinoma,all of whom were in stage Ⅰ B-Ⅱ A and were treated from 2006 to 2012,were enrolled,and some of them received postoperative pelvic radiotherapy ± para-aortic extended field radiation ±afterloading radiotherapy.The chemotherapy regimen consisting of DDP,TP,and FP was given to these patients.The chi-square test was used for comparison of general clinical data,the Kaplan-Meier method was used for calculating survival rates,and the log-rank test was used for survival difference analysis.Results Cervical adenosquamous carcinoma and adenocarcinoma had no significant differences in clinicopathological features (P=0.107-0.639).The high-risk patients with adenocarcinoma had a higher recurrence rate than their low-risk counterparts even after adjuvant radiotherapy or chemoradiotherapy (P=0.000).In the patients treated with surgery and radiotherapy,those with adenosquamous carcinoma had the shortest median survival time,followed by those with adenocarcinoma and squamous cell carcinoma (P =0.134,0.787);in the patients treated with surgery and concurrent chemoradiotherapy,those with adenocarcinoma had the shortest median survival time,followed by those with adenosquamous carcinoma and squamous cell carcinoma (P=0.131,0.643),and the median survival time showed a significant difference between the patients with adenocarcinoma and those with squamous cell carcinoma (P =0.000).In the patients with adenosquamous carcinoma and adenocarcinoma,the patients treated with postoperative concurrent chemoradiotherapy had higher incidence rates of short-term adverse reactions than those treated with postoperative radiotherapy (P=0.037,0.003),but the incidence rates of long-term adverse reactions showed no difference between the two groups of patients (P=0.861,0.655).In the patients with adenosquamous carcinoma,the patients treated with postoperative concurrent chemoradiotherapy had a lower rate of distant metastasis (P =0.003) and prolonged median overall survival and disease-free survival (both increased by 17 months) (P=0.811,0.799),as compared with those treated with postoperative radiotherapy,while in the patients with adenocarcinoma,the median overall survival and disease-free survival were reduced by 11 and 9 months,respectively (P=0.330,0.115).Conclusions Compared with postoperative radiotherapy,postoperative concurrent chemoradiotherapy for early-stage high-risk cervical adenosquamous carcinoma can reduce the rate of distance metastasis.Compared with radiotherapy,postoperative concurrent chemoradiotherapy for adenosquamous carcinoma and adenocarcinoma cannot improve survival time.

Objective To investigate the direct economic loss caused by oral infection in patients with acute leuke-mia.Methods Acute leukemia patients with oral infection in a tertiary first-class hospital in Shandong Province be-tween January 2011 and December 2013 were investigated,the 1 :1 matched case-control method was used for com-paring hospitalization expense and length of hospital stay between oral infected (case group)and uninfected patients (control group ).Results A total of 994 patients with acute leukemia were monitored,277 had healthcare-associated infection,17 (5.56%)of whom were with oral infection.The median hospitalization expense of patients in case group and control group was￥37 327 and￥13 176 respectively,the total hospitalization expense of patients in case group was 2.83 times more than control group,difference was statistically significant (Z = -3.621 ,P <0.001).Each hospitalization expense of case group was higher than control group,especially expense for medicine, blood transfusion,laboratory examination,and therapy.The median length of hospital stay in case group and con-trol group were 17 days and 11 days respectively,rank sum test showed that difference in median length of hospital stay between two groups was statistically significant (Z =-3.627,P < 0.001 ).Conclusion Acute leukemia pa-tients with oral infection have increased hospitalization expense,prolonged length of hospital stay,and increased the financial burden.

Objective To explore influence of norm-setting three-stage rehabilitation training on hemiplegic stroke patients with movement and cognitive dysfunction. Methods A prospective randomized controlled study and stepwise linear regression analysis was carried out to investigate the early variation factors, which affected the integrated functional recovery of stroke patients. According to variation factors we established our norm-setting three-stage rehabilitation training program. 200 patients were randomly selected, according to the cerebral infarction and cerebral hemorrhage classification, and then randomly divided into the rehabilitation group and the control group with 100 patients in each group. All patients accepted general neurology routine nursing. The rehabilitation group was given an extra norm-setting three-stage rehabilitation training. The improvement of motor and cognitive function were observed. Results The early variation factors of integrated functional outcome were treatment programs, CNFD score, age, diabetes, SFMA score, smoking and the intensity of labor within six months since stroke onset. Movement and cognitive function of the rehabilitation group significantly improved than the control group as well as upon admission on the first, 3rd and 6th months since stroke onset. Conclusions The norm-setting three-stage rehabilitation training obviously promotes the improvement of motor and cognitive function at all stages.
