OBJECTIVETo provide quantitative foundation for the diagnosis of atlanto-axial rotatory subluxation by analyzing the various imaging features of normal atlanto-axial joints in neutral position and rotary functional position on the MSCT images.

METHODSForty-one normal volunteers were examined by CT on the atlanto-axial joint in neutral position and rotary functional position. By the observation and measurement of atlanto-dental interval (ADI), lateral atlanta-dental space (LADS), VBLADS and rotating angle of atlas on dentate (RAAD), the imaging manifestations and anatomical characteristics were analyzed and compared. In order to compare VBLADS and RAAD and make a correlation analysis between different age groups, 51 normal volunteers were divided into two groups: age younger than 45 years old group and age older than or equal to 45 years old group.

RESULTSThe dens in neutral position deviated in an angle range of (3.22±0.89)°. The articular facets of lateral atlantoaxial joint in rotary functional position had rotatory displacement and the range of the relative rotation angle was (33.85± 2.79)°. Through the correlation analysis of matching data, it could be concluded that there was no correlation between atlantoaxial relative rotation angle and VBLADS within a certain range. There were statistically differences of atlantoaxial relative rotation angle in rotary functional position between two groups.

CONCLUSIONMSCT imaging in rotary functional position can clearly show the anatomical structure and rotation function of a normal atlanto-axial joint, so as to provide a theoretical basis for the diagnosis of atlanto axial rotatory subluxation.

Coronary atherosclerotic heart disease is the leading cause of death in the world of non-infectious diseases.High density lipoprotein ( HDL ) plays an important role in the progression of anti-atherosclerosis.Recent studies have found that HDL can carry microRNA, and the anti-inflammation function of endothelial cell is achieved by the transport of microRNA.The specific functions of different HDL subtypes in the anti-atherosclerosis have been gradually recognized.At the same time, a series of traditional HDL anti-atherosclerotic functions also have been newly discovered, such as reverse cholesterol transport, antioxidant, anti-inflammatory and the protection of vascular endothelium.All of these advances provide a new basis for the clinical application of HDL.

OBJECTIVE To look into and analyze the application of antibacterial used in our hospital in order to enhance the rationality of clinical usage. METHODS We conducted the survey by means of picking out examples in numbers within a definite range,looking back at the records with regard to it from Jan 2004 to Dec 2004. RESULTS Altogether there were 5 302 medical records.The percentage of using antibacterial was 70.24%,from which 45.22-36.68% were used two kinds and 8.54% were used more than two kinds.As to the basis,preventive use taken up a large proportion,accounted for 48.93%;the main route was by intravenous injection,which added up to 74.03%.Of the antibacterials applied,the first three were penicillins;aminoglycosides;cephalosporins.The percentage for surgical application was 94.49%,from them 57.14% used 2 or more kinds for treatment of incision of type Ⅰ. CONCLUSIONS It is very necessary and urgent to supervise the management of the rational application of antibacterial.

Objective To study the clinical features,diagnosis and management of small cell carcinoma of the bladder (SCCB).Method The clinical data of 18 cases of patients with small cell carcinoma of the bladder were analyzed retrospectively and the literature were reviewed.There were 16 males and 2 females,ages 54 to 81 years (median age,61 years).Clinical manifestations included gross hematuria in 11 cases,urgency in 2 cases,dysuria in 2 cases and postoperative review after TURBT of bladder urothelial carcinoma in 3 cases.The median tumor size was 3.35cm (ranged,1.0 to 6.0 cm).2 cases underwent TURBT and intravesical chemotherapy regularly were followed after surgery.3 cases underwent partial cystectomy,intravenous chemotherapy combined with radiotherapy was followed in one case,the other 2 cases refused the following therapy.13 cases underwent radical cystectomy,intravenous chemotherapy was followed in 2 cases,pelvic radiotherapy was followed in 2 csaes and intravenous chemotherapy combined with radiotherapy was followed in 2 cases,the other 7 cases refused the following therapy.Results 11 cases were pure SCCB,7 cases were mixed SCCB,all with urothelial carcinoma.T1N0M0 in 3 cases,T2N0.1M0 in 4 cases,and T3N0-2M0 in 11 cases.The duration of follow-up was from 5 to 35 months after surgery.9 cases died of tumor metastasis,9 cases are still alive,except 1 case with lymph node metastasis,the other 7 cases are free of tumor recurrence or metastasis.Conclusions SCCB is rare,with high malignant degree and poor prognosis.The prognosis of the pure SCCB may be worse than the mixed SCCB.The diagnosis depends on pathology examination.Radical cystectomy is the main treatment method,the strategy of bladder-preserving may be an attempt for proper SCCB patients.Adjuvant therapy plus surgery may be better.

Objective To observe the preliminary clinical results and safety of 27-gauge microincision vitrectomy surgery for partial vitreoretinal diseases.Methods A total of 13 patients (13 eyes) who underwent 27-gauge microincision vitrectomy surgery were enrolled.The follow-up period was 6 to 12 months.Preoperative and postoperative visual acuity and intraocular,total operative time,cutting time for removing vitreous,wound healing status,intraoperative and postoperative complications were observed.Results Mean best corrected visual acuity improved from preoperative (1.26±0.66) logMAR (0.10±0.09) to postoperative (0.63±0.52) logMAR (0.35±0.24),and the difference was statistically significant (t=2.743,P=0.018).The difference of mean preoperative intraocular pressure (IOP),IOP of postoperative day 1,day 5,one month and final postoperative visit were not statistically significant (F=0.593,P＞0.05).The mean total operative and cutting times were (36.38±14.97) min and (10.12±3.54) min respectively.Postoperative scleral incision showed linear closure,no cases of postoperative sclerotomyrelated complications such as wound dehiscence,vitreous incarceration and subcoujunctival fluid were observed.No intraoperative and postoperative complications of iatrogenic retinal breaks,endophthalmitis,choroidal detachment,retinal detachment and vitrous hemorrhage were observed.Conclusions The 27-gauge microincision vitrectomy surgery can improve postoperative visual acuity for treatment of vitreoretinal diseases and induce fewer sclerotomyrelated complications,which maybe a safer surgical approach.

Objective To investigate the expression pattern of growth arrest-specific transcript 5 ( GAS5 ) in hepatocellular carcinoma and assess its pre-operation and post-operation levels.Methods Totally 243 patients were collected in Zhongnan Hospital in 2015, and were divided into 4 groups: pre-operation (117 cases), 1 weeks after operation (39 cases), patients with hepatitis B (55 cases) and cirrhosis ( 71 cases ) .Meanwhile, 129 controls were collected.The expression of GAS5 in plasma was detected by real-time quantitative PCR. The levels of GAS5 in subgroups were compared by Oneway ANOVA.The relationship between GAS5 and the clinical pathologic features, and its pre-operation and post-operation expression were analyzed by Student′s t test.Results GAS5 was downregulated in HCC plasma and the levels of GAS5 were associated with tumor differentiation ( R2 =0.219,P=0.011) and TNM stage (R2 =0.036,P=0.044).Compared with the levels in pre-operation group (3.958 ±0.282), GAS5 were upregulated after surgery (3.843 ±0.223),t=2.283, P=0.028.In addition, GAS5 expression in well and moderately differentiated HCC was higher than poorly differentiated ones before operation[(3.873 ±0.191) and(4.151 ±0.365),t=2.271,P=0.035], but there was no significant difference after operation[(3.880 ±0.154) and (3.879 ±0.246),t=0.032, P=0.975].The ROC curves indicated that GAS5 had a good sensitivity to differentiate HCC from the healthy ( 88%, 88/100 ) and the cirrhosis ( 90%, 90/100 ) . Conclusion GAS5 might be used to assess the treatment of HCC.

SWNTs are a mixture of 1/3 metallic SWNTs (m-SWNTs) and 2/3 semiconducting SWNTs (s-SWNTs). It is desirable to separate the metallic SWNTs from the semi-conducting ones. In this study m-SWNTs was separated by using a poly[(m-phenylenevinylene)-alt-(p-phenylenevinylene)] (PmPV) derivative and used as photo-thermal media instead of SWNTs. The separation effects of m-SWNTs were evaluated by Raman spectra, molecular modeling and TEM images. The effects of m-SWNTs on MCF-7 cell proliferation and apoptosis were evaluated with MTT assay and flow cytometry, respectively. m-SWNTs were separated with high purity. A strong inhibition of MCF-7 cell growth was observed with the m-SWNTs under near-infrared (NIR) light irradiation. Our results will be helpful for the potential applications of m-SWNTs in clinical photothermal cancer therapy.
