ObjectiveTo relieve the nausea and vomiting caused by chemotherapy in patients with hematologic diseases, and to secure the completion of chemotherapy.Methods320 cases of hematologic patients were divided randomly into 2 groups: the treatment group (160 cases): ondanseton 4 mg and dexamethone 10 mg I.V.; ondanseton group (160 cases): ondanseton 4 mg I.V.ResultsThe effective rate of the treatment group was 98.75%, and that of the ondansetron group was 43.13%. There was a singificantly difference between two groups (P<0.001).ConclusionOndanseton combined with dexamethone has a good effect on the vomiting and nausea induced by chemotherapy.

Objective To observe the therapeutic effect of Tianwang Buxin Decoction for delirium after hip joint replacement in senile femoral neck fracture patients. Methods A total of 57 senile patients with femoral neck fracture induced by falling were enrolled from the department of arthropathy of Zhongshan Hospital of Traditional Chinese Medicine admitted from September of 2009 to February of 2014. The patents were aged over 65 years, and had delirium after hip joint replacement. Random number method was used to divide the patients into Chinese medicine group ( 29 cases) and western medicine group ( 28 cases) , which were given oral use of Tianwang Buxin Decoction and Olanzapine separetely. Before and after treatment, we observed the scores of Delirium Rating Scale (DRS), time for delirium disappearing, and incidence of indifferent mind and somnolence.Results (1) After treatment, DRS scores were obviously decreased in both groups (P<0.01 compared with those before treatment), but the difference was insignificant between the two groups (P>0.05). (2) The difference of time for delirium disappearing was insignificant between the two groups after treatment ( P>0.05). ( 3) After treatment, 7 cases of the control group had indifferent mind or somnolence, accounting for 25%. No case of the treatment group had indifferent mind or somnolence. The difference between the two groups was significant ( P<0.01). Conclusion Oral use of Tianwang Buxin Decoction has the same effect as Olanzapine for the treatment of delirium after hip joint replacement in falling-induced senile femoral neck fracture patients, and has the advantages of having no adverse reaction of indifferent mind or somnolence, and can realize comprehensive treatment by modification of the recipe according to the symptoms.

BACKGROUNDTo find a rapid and sensitive method for early diagnosis of nasopharyngeal carcinoma by using EBV TK kinase.

METHODSProkaryotic expression plasmid pRSETTK was constructed. EBV TK kinase was highly expressed in E.coil BL21 (DE3). The authors identified specificity of TK kinase by Western blot, then used purified TK kinase in ELISA to detect the IgG antibody in the serum of NPC patients.

RESULTSSpecific IgG antibody against TK kinase was found in the serum of NPC patients. The specificity and sensitivity of TK kinase were both 100% in Western blot and were 98.0% and 93.4% respectively in ELISA.

CONCLUSIONSThe EBV TK kinase showed high specificity and sensitivity in ELISA, therefore it can be used for early diagnosis of NPC

In orthodontic and orthognathic practice, cephalometric analysis is an integral tool throughout the clinical process. However, as landmark identification is still unautomated, both the conventional and semiautomated approaches are open to considerable subjectivity and could be time-consuming for inexperienced clinicians. Deep learning (DL), a state-of-the-art artificial intelligence (AI) technique, is highly effective in image recognition. In recent years, many studies have focused on the application of DL in cephalometric analysis, including automated landmark detection, automated diagnosis, cervical vertebral maturation stage determination, adenoid hypertrophy analysis and upper airway identification. Studies show that DL can effectively improve the efficiency of cephalometric analysis. In most studies, the accuracy of DL can reach more than 80%, and its difference from the gold standard is clinically acceptable, demonstrating good potential for future applications. However, most studies are limited to landmark detection, and the broadness and richness of the training dataset are limited. Future studies should broaden the research scope, improve the algorithm, elevate the richness of the datasets, and combine DL with other AI algorithms to improve its accuracy, stability and generalizability.
