Objective To explore the clinicopathology characteristics of endometrial adenocarcinoma and non-endometrial adenocarcinoma.Methods The clinical data of 306 patients with endometrioid cancer were analyzed retrospectively.Results The patients with endometrial adenocarcinoma accounted for 90％ of all patients,and the patients with non-endometrial adenocarcinoma accounted for 10％.Compared with the patients with endometrial adenocarcinoma,the average age of the patients with non-endometrial adenocarcinoma was older[(59.32 ± 7.77)years],the constitution ratio of postmenopausal patients was higher(90％),the clinicopathologic stage was later(P =0.000),the grade of histology was higher(P =0.000),the myometrial invasion was deeper(P =0.014).The patients with nonendometrial adenocarcinoma were prone to occur lymph metastasis(P =0.006),and the recurrence rate was higher(P =0.000).Conclusion There is significant defference between endometrial adenocarcinoma and non-endometrial adenocarcinoma,the patients with non-endometrial adenocarcinoma has poor pronosis,and we should pay more attention to it.

Objective To investigate the incidence and clinical characteristics and look for assay or examination indexes or indicators with higher sensitivity and specificity of heart damage induced by exhaustive exercise in order to establish its preliminary clinical classification and diagnostic criteria. Methods In a military region for training staff,the clinical data of 88 soldiers who were admitted to the departments of cardiology in 6 general or central hospitals because of exhaustive exercise from January 2000 to December 2010 were analyzed. The myocardial enzyme, electrocardiogram(ECG),echocardiography and other related examination indexes or indicators were observed,and the changes of symptoms,signs and other relevant assay and examination indexes before and after treatment were recorded. Results Exhaustive exercise could cause the symptoms such as chest tightness,palpitations,chest pain, dizziness,shortness of breath,fatigue,syncope and other symptoms,as well as cardiac auscultation abnormalities. After treatment, aspartate aminotransferase〔AST(U/L):20.34±6.33 vs. 35.43±25.25〕,α-hydroxybutyrate dehydrogenase〔α-HBDH(U/L):130.47±9.04 vs. 168.93±62.69〕,lactate dehydrogenase〔LDH(μmol?s-1?L-1):2.48±0.62 vs. 3.58±1.34〕,creatine kinase〔CK(U/L):125.58±67.56 vs. 556.42±381.89〕,creatine kinase isoenzyme〔CK-MB(U/L):11.20±4.08 vs. 23.09±15.61〕were significantly lower than those before treatment(P<0.05 or P<0.01);cardiac troponin T(cTnT)was detected in 5 patients,its level after treatment was significantly lower than that before treatment(μg/L:0.07±0.05 vs. 1.26±0.78,P<0.05). The ECG abnormalities included primarily sinus bradycardia (16 cases),sinus arrhythmia (13 cases) and premature ventricular contractions (11 cases). Echocardiographic abnormalities appeared in 18 cases,they were chiefly as follows:valvular regurgitation, cardiac dysfunction,cardiac enlargement,etc,among which the most common one was valvular regurgitation(all the refluxes were of small amount). Based on the above clinical manifestations and examination results,the exhaustive cardiac injuries were preliminarily divided into common type(20 cases),arrhythmia type(56 cases),heart failure type(2 cases)and sudden death(10 cases). Conclusions The clinical manifestations of exhaustive heart damage may appear in different types. Abnormal changes of myocardial enzymes,ECG and echocardiography are the strong evidences for the damage. Clinicians should pay attention to its prevention and treatment.

BACKGROUND:Currently, the treatment of proximal humeral fractures mainly contains joint preservation (conservative treatment, open reduction and internal fixation) and arthroplasty, but how to choose the treatment is stil controversial. OBJECTIVE:To evaluate and compare the clinical outcomes of joint preservation versus arthroplasty in the treatment of displaced 3-or 4-part humeral fractures in randomized control ed trials using meta-analysis. METHODS:Medline (January 1966 to December 2013), PubMed (January 1980 to December 2013), Embase (January 1990 to December 2013), Science (January 1990 to December 2013), Springer (January 1990 to December 2013), China National Knowledge Infrastructure (1994 to 2013), and Wanfang database (1982 to 2013) were searched for randomized control ed trials addressing joint preservation and arthroplasty for 3-or 4-part proximal humeral fractures. Articles meeting the inclusion criteria were included. The related data were extracted and loaded onto Comprehensive Meta-Analysis Software for meta-analysis. RESULTS AND CONCLUSION:Seven articles with 320 patients (165 patients undergoing joint preservation and 155 patients receiving arthroplasty) were accepted in this mete-analysis and al of them were high-quality English researches by modified Jadad Scale. Meta-analysis results displayed that the random-effects mean Constant score across al types was 55.9 (95%CI:50.7-61.1;P<0.001). Constant score was higher in the joint preservation group than in the arthroplasty group (P<0.01). The study displayed significant heterogeneity (I2 0.001). In the meta-analysis, Constant scores were decreased with increasing rate of male to female and rate of tuberosity resorption. These results suggested that 3-or 4-part proximal humeral fractures demonstrate improved Constant scores when treated with joint-preserving options compared with arthroplasty. Moreover, age, fracture pattern, gender ratio and complication rate are significant predictors of the Constant score. Given the observed heterogeneity and variance in treatment techniques in the included studies, more randomized control ed trial studies are needed to definitively recommend joint-preserving techniques versus arthroplasty for treatment of 3-or 4-part proximal humeral fractures.=88%, Q statistic=107.6, Q=13;P<0.001).

Objective To analyze the clinical features and risk factors of migraine patients with white matter le-sions (WMLs). Methods One hundred ten clinically diagnosed migraine patients who underwent magnetic resonance im-aging (MRI) scans from October, 2010 to August, 2013 were enrolled in Shandong Provincial Hospital. One hundred ten migraine patients were divided into two groups:WMLs group and non-WMLs group based on the presence or absence of WMLs in MRI scans. The clinical features of the patients and location and number of WMLs were investigated. Noncondi-tional multivariate stepwise logistic regression after univariate analysis was used to analyze the data. Odds ratio (0R) and 95 confidence interval after adjustment for possible confounding variables were calculated. Results①There were 36 patients with WMLs among the 110 migraine patients. The incidence of WMLs in migraine patients was 32.7%. The WMLs in migraine patients were predominantly present in the frontal and parietal lobes (59.1%). ② Compared with non-WMLs group, there were significant increases in disease duration (5.3±3.7 vs. 7.6±4.9, P﹤0.01), frequency of head-ache attack (3.5 ± 2.3 vs. 4.6 ± 2.2, P﹤0.05), aura (18.9%vs. 36.1%, P﹤0.05) and family history of migraine (12.2%vs. 44.4%, P﹤0.01) in WMLs group.③The independent risk factors of WMLs in migraine patients were family history of mi-graine (OR=5.995), aura (OR=3.067) and long disease duration (OR=1.165). Conclusions Family history of migraine, au-ra and disease duration are the predictive risk factors of WMLs in migraineurs.

BACKGROUND:Tissue-engineered biomaterials have the similar structure and function with autologous tissues. OBJECTIVE:To explore the osteoinduction of the bone biomaterial composited with rat bone marrow mesenchymal stem cel s in the treatment of large costal defects. METHODS:Forty Wistar rats were enrol ed used for the preparation of right large costal defect models, and then randomized into two groups, fol owed by the implantation of calcium chloride-sodium alginate gel (control group) or chloride-sodium alginate-bone marrow mesenchymal stem cel s (experimental group). At 2, 4 and 8 weeks after implantation, chest X-ray radiograph and histological examination of the defect region were conducted. RESULTS AND CONCLUSION:X-ray showed that in the experimental group, the defect area had no significant changes at the 2nd week after implantation until the formation of few bones at the 4th week;and at the 8th week, both ends of the defect region gradual y connected, and newly formed bones were ful of the defect. In contrast, the defect region in the control group showed no obvious bone healing, and both ends of the defect closed and osteosclerosis occurred. In the experimental group, there were a smal amount of fibrous tissues and numerous inflammatory cel s infiltratied in the material compartment, and no connection occured between the material and broken ends;there were numerous inflammatory cel s but no bone tissues in the control group at the 2nd week. At the 4th week, the scaffold degraded gradual y and abundant bone tissues were seen in the experimental group;the scaffold degraded little, and bone tissues aggregatied at the both defect ends in the control group. Up to the 8th week, the two kinds of scaffolds degraded mostly. A large number of bone tissues and trabeculae formed and the both defect ends were connected with the newly formed bones in the experimental groups, while in the control group, osteosclerosis appeared at both ends of the defect. To conclude, the bone biomaterial composited with rat bone marrow mesenchymal stem cel s promotes the repair of large costal defects.

Objective:To observe the clinical efficacy of back-Shu and front-Mu points combination needling on balance and walking function in patients after stroke and its mechanism. Methods:A total of 79 patients with post-stroke balance and walking dysfunction were randomly divided into a control group and an observation group.Both groups received conventional treatments such as dietary guidance and oral medications as well as rehabilitation training.On this basis,the control group was treated with additional conventional acupuncture,and the observation group was treated with additional back-Shu and front-Mu points combination needling.Both groups were treated for 4 consecutive weeks.The thickness of abdominal muscle group(transverse abdominal muscle,rectus abdominis,obliquus internus abdominis,and obliquus externus abdominis),the scores of Berg balance scale(BBS),Fugl-Meyer assessment(FMA),and functional ambulation categories(FAC),and walking velocity and stride were compared between the two groups. Results:During the trial,there was 1 dropout case in the control group and 4 dropout cases in the observation group.Before treatment,there were no statistical differences in the abdominal muscle group thickness,scores of BBS,FMA,and FAC,and walking velocity and stride between the two groups(P>0.05).After 4 weeks of treatment,the thickness of abdominal muscle groups,scores of BBS,FMA,and FAC,and walking velocity and stride in both groups were improved(P<0.01),and the observation group was superior to the control group(P<0.05). Conclusion:Both conventional acupuncture and back-Shu and front-Mu points combination needling are conducive to the improvement of balance and walking function in patients after stroke.The back-Shu and front-Mu points combination needling method has better curative efficacy.Strengthening the core muscle group strength may be one of the mechanisms of back-Shu and front-Mu points combination needling treatment.

To investigate the effects of cycloartocarpin A (ACR-2) and artocarpin (ACR-3), monomeric compounds isolated from Fructus Artocarpi Heterophylli, on apoptosis of SMMC-7721 and SGC-7901 cell lines.

OBJECTIVE: To investigate the effects of three compounds extracted from Tripterygium wilfordii Hook (TW) on angiogenesis in the chick chorioallantoic membrane (CAM). METHODS: Fifty fresh Hongkong Mahua chicken eggs were divided into five groups: PBS-treated group, TW1-, TW2- and TW3-treated groups and Rg3-treated group. After disinfection, the eggs were incubated for six days in a constant temperature box with the temperature being controlled within 37.8 degrees C, then exposed CAM, laid the filter papers with specimen on the CAM, and the eggs were incubated for another two days. CAM was fixed with the mixture of methyl alcohol and acetone at room temperature for about 15 min, and then cutting the CAM, taking photos and observing the angiogenesis in the CAM. RESULTS: There were many CAM vessels in the PBS-treated group and the blood vessel net could be seen clearly. The number of CAM vessels in the TW1-, TW2- and TW3-treated groups (10 microg/egg) was much less than that in the PBS-treated group. Furthermore, the frame of the vessels was not clear, and the color was obscure. Inhibition rates of angiogenesis in the TW1-, TW2- and TW3-treated groups were 80%, 60% and 100% respectively, while the inhibition rate of angiogenesis in the Rg3-treated group (10 microg/egg) was only 10%. CONCLUSION: TW1, TW2 and TW3 can obviously restrain the angiogenesis in CAM and still need further study.

Objective To investigate the microstructural abnormalities of cerebral white matter in patients with medication-overuse headache with diffusion tensor imaging.Methods Diffusion tensor magnetic resonance imaging (DT-MRI) was carried out in 80 migraine patients with medication-overuse headache (case group) and 80 age-and sex-matched healthy controls (control group).Fractional anisotropy (FA) and apparent diffusion coefficient (ADC) were measured and the correlation between clinical characteristics and the changes was examined.Results ① The FA values at the bilateral orbitofrontal cortex,cingulate cortex,splenium of the corpus callosum and the right anterior limb of the capsula interna were significantly lower than those in the controls(P＜0.05).② The ADC values at the right orbitofrontal cortex,left inferior frontal gyrus and anterior cingulate cortex were significantly higher than those in the controls (P＜0.05).③ There were negative correlations between FA values at the bilateral orbitofrontal cortex and right hind legs of the capsula interna and headache course as well as frequency.There was negative correlation between FA values at the left hind legs of capsula interna and headache frequency.④ There were positive correlations between ADC values at the left orbitofrontal cortex and headache course as well as frequency.There were positive correlations between ADC values at the right orbitofrontal cortex and prior cingulate cortex and headache frequency.There was positive correlation between ADC values at the posterior cingulate cortex and headache course.Conclutions There might be an integrity change of neurofibrotic microstructures in the bilateral orbitofrontal cortex and cingulate cortex in patients with medication-overuse headache,FA values are negatively associated with headache course and frequency whereas ADC values are positively associated with headache course and frequency.
