The method of acupuncture combined with rehabilitation training in the treatment of shoulder hand syndrome after stroke is reliablet, quick, with simple operation and less adverse reactions. Among them, characteristic acupuncture could focus on the targeted points with obvious effect than ordinary acupuncture, and the combination with rehabilitation training could greatly improve the curative effect. However, there still exist some problems in the current research, such as the difficulty of conducting blind clinical trials of acupuncture therapy; the lack of follow-up data in the evaluation of curative effect, the uncertainty of long-term curative effect; the small sample size of clinical research, etc., so multi-centered and large sample RCT research are still needed.

Objective To investigate human papilloma virus(HPV) infection in normal endometrium, atypi-cal hyperplasia of endometrium and endometrial carcinoma. Methods By the nucleic acid hybridization,we detected 28 pairs of endometrial carcinomas, 21 pairs of atypical hyperplasia of endometrium. Normal endometrium from 16 pa-tients with uterine myomas were as control. Results HPV16/18 DNA was detected in 25 endometrial carcinoma and 2 atypical hyperplasia of endometrium and 1 normal endometrium. Conclusions Endometrial carcinoma HPV16/18 DNA were significantly higher than those infected with atypical endometrial hyperplasia and normal endometrium. Note the occurrence of endometrial cancer,the development may be associated with HPV infection.

Objective To explore the clinical therapeutic effects in arterial interventional therapy in early osteosarcoma patients.Methods Thirty-eight early osteosarcoma patients received arterial chemoembolization therapies and performed operations.94.7% patients received limb salvage surgeries.Levels of alkaline phosphatase were tested in preoperative and postoperative phases.Results Levels of postoperativealkaline phosphatase[average(191.7±107.0)U/L]were significantly decreased compared with that before interventional therapy[average(1129.1±572.3)U/J.The survival rate in follow-up at 1,3 and 5 years Was97%,79%,50% respectively.The rate of recurrence and metastasis WAg 24%.Conclusions Arterialchemoembolization therapies in patients with early osteosarcoma could improve clinical symptoms effectively,enhance survival rate,relieve recurrence and metastasis,remain affected extremity.The clinical thempeutic effects of iodinated oil were the best among the three embolism materials.

Objective To detect the expression and significance of serum miRNA-183 and TK1 in patients with colorectal cancer, and the mechanism thereof. Methods Fifty-two serum samples of colorectal cancer patients and paired health serum samples were collected. The expression of miRNA-183 was detected by real-time quantitative PCR, and TK1 was detected by Western blot enhanced chemiluminescence assay. The correlation between miRNA-183 and TK1 and their relations with the clinicpathologic characteristics were analyzed. Results The serum miRNA-183 expression was significantly higher in colorectal cancer group than that in normal control group (P<0.01). The expression of serum miRNA-183 was significantly higher in stage Ⅲ-Ⅳ group than that in stage Ⅰ-Ⅱ group (P < 0.01). There was more significant increase in serum miRNA-183 in lymphatic metastasis group than that without lymphatic metastasis group (P < 0.01). Receiver operating characteristic (ROC) curve showed that of there was a diagnostic value for serum miRNA-183 in colorectal cancer, with an optimal value of 1.15. The diagnostic sensitivity and specificity were 78.8%and 67.3%, and the positive predictive value and negative predictive value were 78.9%and 70.2%. The serum TK1 expression was also higher in colorectal cancer group compared with that of normal control group (P<0.01). And the TK1 expression was also higher in stageⅢ-Ⅳgroup than that in stageⅠ-Ⅱgroup (P<0.01). Furthermore, miRNA-183 expression was positively correlated with TK1 expression (rs=0.692, P<0.01). Conclusion The serum expression levels of miR-183 and TK1 may act as tumor markers for early colorectal cancer diagnosis, and also can be used to predict the malignant degree and prognosis of colorectal cancer.

Objective To analyse the clinical features,imaging characteristics diversity of deep cerebral veins thrombosis (DCVT).Methods From 2004 to 2013,6 patients diagnosed as DCVT were recorded and a retrospective review of the cases were undertaken for the purpose of this analysis.Results Among the 6 patients with DCVT,4 were male and 2 were female,aged from 28 to 69 years old.The disease duration of 4 cases ranged from 2 to 7 days,remnants were 20 days and 3 months respectively.The first symptoms of 4 cases were headache,1 was feeblemindedness,and the other was hemiplegia.The secondary symptoms were disturbance of consciousness,apathy,diplopia and non-infectious fever.Non-contrast computed tomography showed low signal in the bilateral thalamus in four patients,high signal in the transverse sinus and straight sinus in one patient and high signal in torcular in one patient.Abnormal signal was found in bilateral thalamus on magnetic resonance imaging in all patients and some of them had abnormal signal in the mesencephalon or basal ganglia.The patients were definitely diagnosed as DCVT by magnetic resonance venography (MRV) or digital subtraction angiography (DSA).Among them,2 patients were confirmed by brain biopsy.Four patients were followed up with good outcome and 2 were lost to follow-up.Conclusions The clinical manifestations of DCVT are not specific.For acute-onset DCVT patients,the first symptoms are always headache and vomiting,while the main symptoms are declined cognition and slow reaction for chronic-onset ones.Along with the progress,the main symptoms of DCVT are disturbance of consciousness,psychiatric symptoms and intracranial hypertension.Changes in the bilateral thalamus and basal ganglia are especially main characteristics which are easily misdiagnosed as brain tumor according to the images.DCVT can be definitely diagnosed by no signal of deep cerebral veins on MRV or DSA.
