Objective To investigate the performances and characteristics of femoro-acetabular impingement (FAI)on MSCT. Methods Hips jointed MSCT scans of 109 cases (as case group)and the other 120 cases (as control group)were analyzed retrospec-tively,to analyze the anatomy and osseous abnomality of FAI.Alpha angle,offset,CE angle were measured.The data were tested by using t test and ANOVA test.Results There were 57 cases of osseous protuberance at the femoral head and neck joint,26 cases of the offset reduction,17 cases of over-coverage acetabulum,41 cases of over-deep acetabulum,20 cases of acetabular retroversion,57 cases of subcortical cystic degeneration at the femoral head and neck joint and 22 cases of subchondral cystic degeneration at the ace-tabulum margin.Significant statistical differences were found between case group and control group in alpha angle value,offset and CE angle (P<0.05).Multiple comparisons demonstrated that except results between the value of alpha angle of Cam-type and Mixed-type(P=0.071),Pincer-type and the control group(P=0.083)with no statistical significance,the differences between any other two groups reached statistical significance (P<0.05).Multiple comparisons demonstrated that except result between the value of offset of Cam-type and Mixed-type(P=0.561)with no statistical significance,the differences between any other two groups reached statistical significance (P<0.05).Multiple comparisons demonstrate that except results between the value of CE angle Pin-cer-type and Mixed-type (P=0.444),Cam-type and the control group (P=0.236)with no statistical significance,the differences be-tween any other two groups reached statistical significance (P<0.05).Conclusion Different type of FAI has its unique anatomical features.Alpha angle,offsetand CE angle for the diagnosis of FAI have important reference values.

Objective To evaluate the safety and efficacy of Voriconazole on invasive fungal infections in very elderly patients.Methods Clinical data of 24 very elderly patients with invasive fungal infections who had sought treatment at the Department of Geriatrics of our hospital from April 2013 to April 2014 were retrospectively investigated.The classifications and quantities of fungi,accompanying symptoms,adverse reactions,blood tests,and liver and kidney function indicators were recorded and analyzed before and after treatment.Results Each of the 24 cases was found to have been infected with one or more of 17 fungal strains belonging to the genus of Candida.The rate of complete fungal elimination after treatment was 70％ (12/17).Of the 24 cases,5 achieved a full recovery(20.8 ％),10 (41.7 ％) had significant improvement,5 (20.8 ％) had some improvement,and 4 cases(16.7％)showed no therapeutic benefits,with a total effectiveness rate of 62.5 ％.There was no significant difference in liver and kidney function before and after treatment(P＞0.05).A transient increase in serum creatinine occurred in 1 case and defective vision in another patient during Voriconazole treatment.Conclusions The incidence of invasive fungal infections is high in very elderly patients,with Candida as the main pathogen.Voriconazole is effective in treating invasive fungal infections in very elderly patients,and close monitoring of liver and kidney function is required during voriconazole treatment.

Objective To study the correlations between the levels of inhibition C (Cys-C), glycosylated hemoglobin A1c (HbA1c) and the coronary lesion. Methods 184 patients were divided into the coronary heart disease (CHD) group (n = 113) and the control group (n = 71) according to coronary angiography. The correlations between the level of Cys-C, HbA1c and Gensini score and coronary vessel lesions were investigated. Results The levels of Cys-C and HbA1c of CHD group were significantly higher than the control group (P<0.05). The levels of Cys-C and HbA1c were positively correlated with Gensini score (r = 0.452, 0.570; P < 0.05). The levels of Cys-C and HbA1c were positively correlated with coronary vessel lesions (P<0.001). Multivariate analysis showed Cys-C and HbA1c were significantly associated with Gensini score (β = 0.221, t = 2.516, P < 0.013;β=0.525, t = 6.342, P < 0.001). There was no significant correlation between the level of Cys-C and Gensini score in the subgroup A (r = 0.102, P = 0.418), and the level of Cys-C was positively correlated with Gensini score in the subgroup B (r=0.440, P<0.002). Conclusions The levels of Cys-C and HbA1c are independently associated with the severity and the vessels of the coronary stenosis. Clinically, the joint detections of the levels of Cys-C and HbA1c are a higher predictive value for coronary artery lesions.

Objective To study the visual attention of mild cognitive impairment patients (MCI)by eyes movement training. Meathods 48 mild cognitive impairment patients were divided into eye movement training group,finger training group and untreated control group by single-blind randomized block method. Then they were trained respectively three months. Event-related potentials (ERPs) were used to measure the face recognition of them before and after training. The amplitude and latency of P3b elicited by target stimuli and P3a elicited by new stimuli of the three said groups were compared and contrasted. Results After training,the amplitude of P1 elicted by novelty stimulus were larger in eye movement training group( (6.78 ± 1.55 ) μV) and in finger training group ( ( 5.43 ± 1.47 ) μV) than untreated control group ( ( 3.09 ± 0.98 ) μV) significantly, especially in the frontal area. The amplitude of P1 elicted by target stimulus were larger in eye movement training group( (6.75 ±2.01 ) μV)than in finger training group( (4.12 ± 1.33 )μV)and untreated control group( (3.45 ± 1.01 )μV)significantly, especially in the frontal area. The amplitude of P3a were larger in eye movement training group( ( 10. 19 ± 3.09)μV ) than in finger training group ( ( 7.57 ± 2.66 ) μV ) and untreated control group ( ( 6.06 ± 2.03 ) μV ) (P ＜ 0.05,P＜0.05) significantly,especially in the frontal area. The latency of P3a were earlier in eye movement training group( (390.67 ±55.03 ) ms) compared to finger training group( (428.55 ± 48.68 ) ms) and untreated control group( (435.89 ± 59.21 )ms)significantly, especially in the frontal region and central parietal area. Conclusion Eyes movement can improve the MCI patients' non-selective attention function, especially in frontal area.The finger execrises have no significant effect on visual attention.

The acupuncture manipulation is an important factor for achieving a good therapeutic effect in acupuncture practice.The authors review recent studies on acupuncture manipulation and its qualification from a) differences of the therapeutic effects of acupuncture manipulation,b) quantification of acupuncture manipulations,and c) instruments for delivering and sampling the analogued parameters of different acupuncture manipulations,computer analysis software,etc.Most studies revealed that different acupuncture manipulations had different clinical efficacies.Meanwhile,researches on the quantification of acupuncture manipulations and some related instruments also have made a bigger progress.Nevertheless,there still exist many problems,such as difficulties of various acupuncture techniques in unification in clinic,stronger personal subjectivity in performing manipulations,etc.We should overcome these problems and conduct more researches,so as to raise the clinical curative effect further.

Objective To approach the feasibility of the development and routinely carrying out of gynecological analgesia. Methods A total of 286 pregnant women, 58 were primiparae with full-term fetus and 228 were for mid-term delivery or induced abortion, were enrolled in present study. The combined lumbar-epidural analgesia (CLEA) and the patient-controlled epidural analgesia (PCEA) were given to the primiparae and the ones for mid-term delivery, and the intravenous anesthesia was given to those for induced abortion. Results Among the primiparae and the ones for mid-term delivery, VAS scores were rapidly reduced from 87.7?12.5 and 51.1?14.1 to 8.7?8.8 and 10.6?6.2, respectively, within 3 minutes by CLEA, the effective rates of analgesia were 94% and 100%, respectively. For all of them the Bromage evaluation was in 0 degree. After the induction of labor, no algesia memory existed in the women for induced abortion, the operative time was 15.28?2.57 minutes, the dosage of propoful was 162.9?39.8 mg (about 3mg/kg), and the dosage of fentanyl was 0.05 mg. The incidence of hypotension after intravenous anesthesia was 5.8%. Conclusions Intravenous anesthesia with propoful may remit the panic and fearful sense of pregnant women to induced abortion, and reduce the pain during operation. It is suggested to develop widely and carry out routinely the intravenous anesthesia as an effective and safe technique in gynecological analgesia.

Objective To investigate the effect of low 1evel laser treatment (LLLT) on periodontal clinical index,high-sensitivity C-reactive protein (hs-CRP) and metabolic control in patients of type 2 diabetes mellitus combined chronic peridontitis.Methods Nighty patients with type 2 diabetes combined chronic peridontitis were divided into three groups:initial periodontal therapy (group A),initial therapy combined with LLLT (group B) and control group (group C).The periodontal clinical parameters including periodontal probing depth (PD),clinical attachment loss (CAL),sulcus bleeding index (SBI),hs-CRP,HbA1c and fasting blood glucose (FBG) were tested before and at three months after therapy.Results The periodontal clinical parameters (PD,CAL,SBI) and hsCRP in group A and B improved significantly compared with that of group C after therapy (P＜0.05),with group B had more significant difference (P＜0.01).For the levels of HbA1c and FPG,group A and B showed downtrend,and more obvious outcome was detected in group B (P＜0.05).Conclusions LLLT can effectively improve periodontal status,hs-CRP levels and metabolic control of patients with type 2 diabetes combined with chronic peridontitis,and thus to prevent the occurrence of diabetes complications.

Objective To summarize the clinical features,treatment and prognosis of bullous systemic lupus erythematosus (BSLE).Methods Clinical data were collected from 6 cases of BSLE between May 2009 and September 2015,and were analyzed retrospectively.Results Among the 6 patients,2 were male and 4 were female.The mean age of onset was 34 years.All the 6 patients presented with tense blisters and bullae arising on an erythematous base or normal skin,which were arranged in an annular pattern in 3 patients.The SLE Disease Activity Index (SLEDAI) score was ＞ 4 in all the 6 patients.Histopathological examination showed subepidermal blisters or fissures in all the patients.Direct immunofluorescence (DIF) revealed continuous linear deposition of immunoglobulin G (IgG),IgM and IgA in all the patients,linear deposition of C3 in 4 patients,and linear deposition of Clq in 2 patients at the basement membrane zone (BMZ).All the 6 patients were treated with oral glucocorticoids and hydroxychloroquine,and 2 patients were additionally treated with cyclophosphamide.During the follow-up period,adverse reactions to different extents were observed in the 6 patients.Conclusions BSLE mainly occurs in young and middle-aged people.Histopathologically,subepidermal blisters or fissures can be observed with linear deposition of IgG,IgM,IgA,or C3 along the basement membrane zone on DIF.
