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 investigate the effects of recombinant human interluekin-1 receptor antogonist (rhIL-1Ra) on the cartilage repair in rat temporomandibular joint(TMJ) with osteoarthritis(OA).Methods:Collagenase-Ⅱ was injected into bilateral TMJs of 24 adult rats for the induction of bilateral TMJOA,1 week after injection,5μg rhIL-1Ra(diluted in 0.05 ml normal saline) was injected into each right TMJ and the left joint received the same amount of normal saline injection as the control.12 animals were sacrificed at 2and 4 weeks after the first injection respectively.HE staining,immunnohistochemical method and RT-PCR examination were conducted.Mankins scere was used to evaluate the TMJOA degree.1 adult SD rat was used as healthy control,and sacrificed at 2 weeks of the experiment.Results:The TMJs of both sides showed typical OA-related cartilage degradation 2 week after IL-1Ra treatment,the Mankin~ score of the IL-1Ra treated and control joints was 1.33±0.52 and 2.00±6.63 (P＞0.05),4 week after treatment that was 3.00± 0.63 and 6.50 ± 0.84 (P＜0.05),respectively.Lower expression of ADAMTS-4 and ADAMTS-5 was observed in the treated joints than in the controls (P＜0.05).Conclusion:Intra-articular injection of IL-1Ra into TMJ can alleviate the cartilage lesion,the mechanism may lie in the inhibition of the expression of ADAMTS-4 and ADAMTS-5.

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.

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.
