Objective To study the possibility of ultr asonic examination in evaluation of cleft palate repair. Methods The length, open-close movement of soft palate and velopharyngeal insufficiency were observed by ultrasonography in submaxillary region pre-operation and post-operation in 7 patients. Results After operation- the length of soft palate was longer than that before operation, the mean extended length was 13.7- mm; the movement of soft palate was increased; the velopharyngeal insufficiency was improved. Conclusions The observation of soft palate structure pre-operation and post-operation by ultrasonic examination is an objective index for evaluating the cleft palate repair.

Objective To investigate the CT features of the central nervous system in congenital syphilis infant. Methods CT findings of central nervous system in 11 infants with clinically proved congenital syphilis were analyzed retrospectively. Results CT findings in 10 syphilis neonates were diffuse hypodense lesions in the white matter, with subarachnoid and intra-encephalic hemorrhage in 3 and 1 cases, respectively. One 2-month-old syphilis infant case and 5 cases of follow-up after 45 days to 6 months of treatment demonstrated bilateral widened sulci and cistern with enlarged ventricles in 3 of them. Conclusion CT findings of the central nervous system in congenital syphilis infant are similar to those of hypoxic-ischemic encephalopathy in neonates, and extra-encephalic hydrocephalus or brain hypogenesis ensues later on.

Objective To study the risk factors related to early neurological deterioration (END) in patients with recurrent cerebral infarction (RCI). Methods Three hundreds and twenty-six RCI patients admitted to our hospital from January 2014 to March 2015 were divided into END group (n = 66) and non-END group (n =260). The clinical and laboratory data were collected, and their cerebrovascular lesions were accessed according to the angiographic findings. Results (1) Single factor analysis showed the level of cholesterol was significantly higher in the END group than that of the non-END group (P < 0.05). The proportion of patients suffering from smoking, arterial occlusions, early onset stroke associated pneumonia (SAP) and hyponatremia was also higher in the END group (all P < 0.05). (2) Logistic regression analysis showed that arterial occlusions (OR = 2.137, 95%CI 1.093~4.181), SAP (OR=2.001, 95%CI 1.023~3.912) and hyponetremia (OR=2.467, 95%CI 1.217~ 5.000) were independent risk factors for END of RCI patients (all P < 0.05). Conclusion Arterial occlusions, SAP and hyponatremia may be used as predictors of the early development of RCI patients.

Objective To study the influence of progesterone on the cell proliferation of hormone?dependent breast cancer and observe the co?effect of vitamin D and progesterone of different levels on the proliferation of the cell line T?47D in hormone?dependent breast cancer and the interaction be?tween vitamin D and progesterone. Methods The cultured T?47D cells were divided into the high and the low progesterone mono?treated groups to observe the effects of different levels of progesterone on the cell proliferation of hormone?dependent breast cancer cell line(T?47D). The high and the low vitamin D mono?treated groups were set to observe the effects of different levels of vitamin D on the cell proliferation. Groups treated by differ?ent levels of progesterone combined with vitamin D were set to observe the interaction between them. Normal breast cancer cells were set as the con?trol group. The two?factor two?level parallel factorial experiment was conducted to observe the co?effect of different levels of progesterone and vitamin D on the proliferation of T?47D. The growth and apoptosis of cells was observed through detection of absorbance in each group by MTT. Results The cell concentration in high and low progesterone treated groups was increased than that in the control group,and was increased in the low proges?terone treated group compared with the high progesterone treated group(P<0.05). The cell concentration in dual?low level treated group was de?creased than that in the other three groups which were two?factor treated and the control group(P<0.05). Conclusion Progesterone stimulates the cell proliferation of hormone?dependent breast cancer. The concentration?based interaction between vitamin D and progesterone indicates that the bi?directional effect of progesterone on breast cancer cells may be related to the concentration of progesterone and other factors,but the specific interac?tion and the mechanism is unclear.

Objective:To provide policy recommendations for Beijing public health departments to grasp the dy-namic allocation of healthcare resources and the advantage of medical functional dispersal, and making appropriate health policies to rationally adjust the allocation of health resources. Methods:To study the dynamic function of Bei-jing medical, this study uses the method of accounting of cases summary of the annual report on health finance through the descriptive analysis of the gross fixed capital formation in various regional government-run health facili-ties. Results:The results of this study show that the quality of medical health administrative resources was higher, but effectively dispersed in 2015. By contrast, the basic public health resources allocation was unbalanced. Conclu-sion:This study puts forward the corresponding health policy suggestions. On one hand, it is important to make fur-ther policy to encourage high quality medical resources to be effectively relieved and the regional planning should be done according to market demand by avoiding the blind construction at the early stages. On the other hand, much at-tention should be paid on the balanced development of the basic public health service ability and the coordinated de-velopment of administrative capacity in health, and supporting policies should be formulated, which should rationally allocate the public health resources for a better overall medical functional dispersal.

ObjectiveTo detect the value of ultrasound-guided steroids injection for the treatment of plantar fasciitis.MethodsThirty-eight physical therapy ineffective plantar fasciitis patients were enrolled in this study, and randomly divided into ultrasound-guided and palpation-guided groups. Pain intensity was measured using a visual analog scale (VAS) and plantar fasciitis were evaluated by high frequency ultrasound including assessment of the thickness before injection and at 4 weeks, 12 weeks post injection.ResultsThirty-eight patients who received either ultrasound guided or palpation-guided injection had significantly lower visual analog scale scores and lower plantar fascia thickness (bothP<0.01) at 4 weeks, 12 weeks post injection. The differences in plantar fascia thickness, VAS score between the two groups before, and at the 4 weeks follow-up were not statistically significant [2.52±0.77vs 2.68±0.82,P>0.05; (4.56±0.25) mmvs (4.72±0.38) mm, P>0.05]. However, the ultrasound guided group had lower mean visual analog scale score (1.47±0.77vs 2.37±0.68,P<0.01) and lower mean plantar fascia thickness [(4.02±0.24) mmvs (4.53±0.35) mm,P<0.01] than the palpation-guided group at 12 weeks post injection. The calcification of the plantar fascia at 12 weeks post injection in ultrasound guided group was completely disappeared or significantly decreased.ConclusionUltrasound-guided injection for treating plantar fasciitis is more accurate and effective than palpation-guided injection, and is of great clinical value for both patients and doctors.

ObjectiveTo evaluate the effectiveness of ultrasound-guided (US-guided) subacromial bursa injection of betamethasone combined with hyaluronate for treatment of subacromial bursitis.MethodsA total of 72 patients who were diagnosed as subacromial bursitis by ultrasound and then decided to performed US-guided subacromial bursa injection were randomly divided into two groups. The study group was treated with compound betamethasone suspension followed by sodium hyaluronate, and the control group was treated only with compound betamethasone suspension. Visual analogue score (VAS) and the shoulder active abduction range of motion (AAROM) score were observed before treatment, 1 week and 4 weeks post-treatment during 1 month's followed-up.ResultsThere were signifi cantly decreased in VAS score and increased in AAROM score at 1 week and 4 weeks post treatment for both groups (bothP<0.05). There was no difference of both VAS score and AAROM score between the two groups at 1 week post treatment (bothP>0.05). But at 4 weeks post treatment, the VAS score of the study group was signifi cantly lower than that of the control group (2.08±1.95vs 3.14±2.0,P<0.05), while the AAROM score of the study group was signifi cantly higher than that of the control group (7.12±2.10vs 6.11±1.93,P<0.05). ConclusionsUltrasound-guided subacromial bursa injection of betamethasone combined with hyaluronate is effective in treating subacromial bursitis. It produces better pain and active abduction functional improvement than betamethasone at a short-term follow-up.
