Cone-beam computed tomography (CBCT) has an important function in understanding implant operations. CBCT can be used to evaluate the basic condition of implant site before implant operation and decide whether it is suitable for implanting. CBCT also ensures whether the direction of implant and the operation method are satisfactory. CBCT can be used pre- or post-operation as long as the case involves the maxillary sinus. Clinical implant cases using CBCT were introduced to evaluate the maxillary sinus pre- or post-operation.

Objective:To review the application of aesthetic incision design in the treatment of maxillofacial bone fracture.Methods:53 cases of different types of maxillofacial fractures were treated by oral incision,outlet incision or outlet combined with oral incision and corresponding fix method.The patients were followed up for 6 -18 months.Results:X-ray examination showed that all fractures were well cured.Mouth opening and occlusion were recovered to normal in all cases without obvious scar on maxillofacial skin.Con-clusion:Well designed incision and the corresponding fixed method may guarantee good cosmetic results and bone healing in the treat-ment of maxillofacial bone fracture.

Objective To assess the efficacy,compliance and safety of ketogenic diet (KD) for children with infantile spasms,thus to provide an effective basis for the treatment of infantile spasms.Methods Twenty-five patients with infantile spasms were treated with KD.The gas chromatography-mass spectrometry and high performance liquid chromatography-mass spectrometry (HPLC-MS/MS) were used,except for metabolic diseases,to detect the blood routine,urine,stool,blood Iipids,liver function,as well as electrocardiogram (ECG),electroencephalograph (EEG),ultrasound of the urinary system and other related checks of all patients.The KD antiepileptic drug therapy was given after all children were admitted to hospital,and KD started directly in all patients without fasting.The efficacy compliance and safety were followed up in this study.Results KD maintenance therapy for 1 month,3 mouths,6 months were given to 25 cases (100％,25/25 cases),to 22 cases (88％,22/25 cases),and to 10 cases (40％,10/25 cases),respectively.Among them 7 patients (28％,7/25 cases) were in complete control of seizures within 1 month.Up to Class Ⅱ,Ⅲ efficacy level accounted for 32％ (8/25 cases),12％ (3/25 cases),respectively.Thirteen cases of children had varying digestive symptoms,10 cases of them developed asymptomatic hypoglycemia,and 9 cases of children had sleep trouble during KD treatment,but after symptomatic treatment,children's adverse reactions almost subsided.Only 4 cases of children discontinued treatment due to adverse reactions.All children's seizures were fully controlled.Conclusions The effect of KD is sure in the treatment of infantile spasms.Although KD has some adverse reactions,but it can be tolerated;serious body organ dysfunction treated by KD + antiepileptic drugs combination therapy for 1 to 6 months is not found yet,so the therapy is worthy of promotion clinically.

Objective To analyze the feasibility of theone-cardmode for division-level cadres hospitalized at military hospitals, and to provide reference for application of this mode to cadres under the regimental level who are hospitalized at military hospitals.Methods A 4-month pilot project was carried out among division-level cadres in Lanzhou, Jinan, Nanjing and Chengdu.Data collection and statistical analysis were conducted through the monitoring platform established in the administrative section.Results Division-level cadres outside the system mostly chose division-level hospitals.Patients thended to be hospitalized at nearby or high-quality hospitals mainly due to cardiovascular and cerebrovascular diseases and malignant tumor.Accommodation was not difficult.Conclusion The one-cardmode is feasible at military hospitals for division-level cadres, but the current system of initial diagnosis at basic medical institutions should be maintained.An information sharing platform of electronic medical records should be built to implement inter-hospital linking and sharing of diagnosis and treatment information.A budget subsidy mechanism should be established to normalize hospitalization.

It is a crucial question whether it is necessary to continue the treatment after the patients with chronic myeloid leukemia (CML) who have achieved a complete molecular response (CMR) on imatinib (IM) treatment. If tyrosine kinase inhibitor (TKI) therapy was required indefinitely to maintain CMR, the problems of financial burden and adverse effects would be increased. Approximately 40 ％ of patients with a stable CMR for at least 2 years could stop IM treatment and remain in molecular remission for at least 2 years without IM treatment. Therefore, the ultimate aim should be to give the patients long-term disease control without the need for ongoing treatment. Here the studies progresses of discontinuation of TKI therapy in CML reported in the 53th American Society of Hematology (ASH) annual meeting were reviewed.

Objective To investigate the relationship of the occurrence of sinusitis with nasal septum devia-tion.Methods 102 patients with nasal septum deviation confirmed by spiral CT and sinus endoscopy were included. The coronal CT images of all cases were observed.The incidence of sinusitis in different type of nasal septum deviation was calculated and the correlation between sinusitis with nasal septum deviation was analyzed.Results Among 102 patients with nasal septum deviation,deviated septum at high position in 71 cases,deviated septum beyond high position in 31 cases.Sinusitis was detected in 67 cases,accounted for 65.6%,of which unilateral involving in 38 cases,bilateral involving in 29 cases.Main lesions in the nasal septum deviation concave side in 46 cases (68.7%),in nasal septum convex side in 12 cases (17.9%).Conclusion Deviated septum is an important factor in onset.Upper septum deviation and deviated concave side more likely arise sinusitis.

Objective To investigate the effects of recombinant bovine basic fibroblast growth factors combined with new rehabilitative liquid on neonatal diaper dermatitis. Methods One hundred and twenty neotates with neonatal diaper dermatitis from August 2013 to July 2014 were randomly divided into the control group and experiment group, 60 cases in each group. The control group was treated with conventional care, while the observation group with recombinant bovine basic fibroblast growth factors combined with new rehabilitative liquid. The total effective rate and the treatment time were compared between the two groups. Result The total effective rate of the observation group was significantly higher than that of the control group (P<0.05) and the treatment time of the observation group was statistically significantly shorter than that of the control group (P<0.05). Conclusion Recombinant bovine basic fibroblast growth factors combined with new rehabilitative liquid is effective in the treatment of neonatal diaper dermatitis and it is worth promoting and using clinically.

Hepatocyte nuclear factor 4α is a transcription factor of the nuclear hormone receptor superfamily and plays a very important role in the differentiation and development of the digestive system as well as the polarity regulation,which is considered to be a tumor suppressor gene.It also plays a very important role in digestive tumorigenesis,invasion and metastasis of hepatic carcinoma,colon cancer and gastric cancer,which is closely associated with epithelial-to-mesenchymal transition,the regulation of cell proliferation and wnt signaling pathway.HNF4α expression and its regulation mechanism in the digestive system tumors are now the research focus.

Purpose: To evaluate the diagnostic utility of detection of Cytokeratin 19 (CK19), b-100 protein and epithelial membrane antigen ( EMA) in thyroid papillary carcinoma, follicular carcinoma and papillary hyperplasia. Methods: 65 thyroid lesions were stained immunohistochemically for CK19, S-100 protein and EMA. Results: CK19, S-100 and EMA are negative in all papillary hyperplasia. CK19 expression was strong and diffuse in 100% of papillary carcinoma including the follicular variant of papillary carcinoma, and was positive in 22% of follicular carcinoma. S-100 and EMA were respectively present in 61% and 100% of classic papillary carcinoma, in 38% and 54% of follicular variant of papillary carcinoma and in 44% and 11 % of follicular carcinoma. Conclusions: Our observations suggest that the expression of CK19, in combination with S-100 and EMA expression, is helpful in the diagnosis of thyroid lesions. CK19 is a valuable marker in the distinction of papillary carcinomas from papillary hyperplasia.
