Objective: To analyze the imaging features of mycoplasma pneumonia in order to improve the early diagnosis and treatment of mycoplasma pneumonia as well as reduce misdiagnosis. Methods:Multislice CT data of 31 mycoplasma pneumonia patients during 2012.4 to 2014.4 in our hospital were retrospectively analyzed. Results:Multislice CT results showed that 22 cases(70.97%) occurred in one side of lung, in which 12 cases (38.71%) located in the left lung(two cases located in the lobi superior(6.45%)and 10 cases located in the lobi inferior(32.26%));10 cases (32.26%) located in the right lung , in which 4 cases located on the lobi superior (12.90%), four cases at the lobi inferior(12.90%), two cases involved both lobi medius pulmonis and lobi inferior(6.45%). 9 cases (29.03%) were double lung involvement. The changes of CT are diverse which included glass-like images, consolidation, air bronchogram, bronchial vascular bundle thickening, pleural effusion and mediastinal lymph nodes enlargement. Conclusion:Patients with mycoplasma pneumonia always have varied radiographic changes and chest multislice CT has a certain sense of early diagnosis.

[Objective] To investigate the diagnosis and treatment of congenital oblique talus in clinical practice.[Methods]Clinical situation of thirty-one patients displayed tarsoptosis and pas valgus,collapse in medial longitudinal instep,and with no talipes calcaneus,no contraction of tendon and no rigidity.All instep of the patients were restored to normal by chirismus.The X-ray of normotopia showed that axial ray of talus was declivent to wall and was angulated with No.1 metatarsal bones.The X-ray of lateral position showed that semiluxation of articulatio talonavicularis was noted,and axial ray of talus and No.1 metatarsal bones was not normal.The X-ray of lateral position of maximal plant flex and entropion showed that axial ray of talus and No.1 metatarsal bones was normal.Twenty-seven cases were cured by manipulation,4 cases were cured by operation,31 cases were cured by orthopaedic orthosis.[Results]All cases were curative during a follow-up of 12 to 24 months(mean,10 months).All outline forms of feet were good and no valgus calcaneus was found,the medial longitudinal instep were restored,the function of ankle and toes was normal,and the pedal force of enstrophe with ecstrophy was balance.The X-ray of normotopia showed that the angle of axial ray of talus to No.1 metatarsal bones was normal in 26 cases and ≤10? in 5 cases.Kite's angle was normal in 29 cases and ≤20? in 2 cases.The X-ray of lateral position showed that articulatio talonavicularis was good in 29 cases and ≤25? of talus to calcaneus in 6 cases.[Conclusion]Congenital oblique talus in infants can be cured by manipulation or operation.The prognosis is good.

Objective To investigate the clinical efficacy of paraspinal muscle gap approach in the short segment internal fixation of thoracolumbar fractures.Methods Forty-five patients with thoraco-lumbar fractures but without spinal decompression underwent posterior short segment internal fixation,in-cluding 20 cases via paraspinal muscle gap approach(group A)and 25 cases via traditional posterior mid-line approach.Operative time,intraoperative blood loss,postoperative drainage,visual analogue scale (VAS)score,correction rate of Cobb angle and correction rate of vertebral collapse were recorded and the surgical results were compared between the groups.Results All patients got bony union without internal fixation loosening,broken nails or broken rods.There were significant differences in operative time [(88 ± 17)min vs(105 ±14)min],blood loss [(121 ±24)ml vs(230 ±31 )ml]and postoperative drainage [(66 ±28)ml vs(250 ±45)ml]between group A and B respectively(P<0.05).The differences in cor-rection rate of the Cobb angle [(82.3 ±1.58)% vs(83.5 ±3.71)%],correction rate of the vertebral collapse [(88.22 ±3.18)%vs(87.19 ±2.16)%]and postoperative VAS score were not significant be-tween group A and B respectively(P>0.05 ).Conclusion Internal fixation via paraspinal muscle gap approach has the advantages of less trauma,simple approach,short operative time,less blood loss,quick recovery after surgery.It is consistent with the modern concept of minimal invasion and worthy of sprea-ding.

Objective To study the effects of integrated liposomal prostagladin E 1(Lipo PGE 1) and fosinopril on early diabetic nephropathy (DN) and clinical DN.Methods 86 patients of type 2 diabetic patients with DN were randomly divided into control group (fosinopril) and treated group(fosinopril+Lipo PGE 1).UARE,Scr and BUN figures were compared between two groups before treatment and eight weeks after treatment.Results UAER had been decreased significantly in both groups(P0.05).Furthermore,no significant decrease of BUN、FBG、MPA、TC and TG had been found in both groups.Conclusion Integrated Lipo PGE 1and fosinopril can ameliorate proteinuria and improve renal function of the patients with early DN and clinical DN of normal renal function.

To meet the need of accurate positioning for biopsy gun in the breast biopsy operation, a new stereotactic biopsy guide device have been developed to adapt to the domestic mammary machine, which can help physician to carry out biopsy operation more accurately and effectively. The guide device has the motion model, measurement model and display model and can realize linear motion and display real-time displacement values in X, Y and Z direction. The experimental results showed that the guide device could be well fixed in the domestic mammary machine, and achieved good accuracy and repeatability in each direction. Depending on the displacement values, physician can change the space of biopsy gun accurately.

Objective To explore the clinical effect of reconstruction of coracoclavicular and acromioclavicular ligaments with multi - bundle - polystyrene - suture for treatment of Ⅲ degree acromioclavicular dislocation. Methods 30 patients with Ⅲ degree acromio-clavicular dislocation were randomly divided into two groups. Multi - bundle - polystyrene - suture was used to reconstruct coracoclavicular and acromioclavicular ligaments in treatment group; Cross - Kirschner and tension bands or clavicular hook plates were used to reconstruct coracoclavicular ligaments in control group. Then the clinical effects of the two methods were analyzed and assessed clinically. Results The clinical effects of treated group was significantly better than those of the control group on the volume of blood loss, surgical time and shoulder function. Conclusion It is a simple, minimally invasive, inexpensive and effective method. We need not to remove the internal fixation to reconstruct coracoclavicular and acromioclavicular ligaments with multi - bundle - polystyrene - suture for treatment of Ⅲ degree acromioclavicular dislocation.
