Objective To observe the effect of extracorporeal shock waves (ESW) therapy on avascular necrosis of femoral head (ANFH) of stage IV. Methods 72 hips of 44 patients with ANFH of stage IV, according to Association Research Circulation Osseous, were randomly divided into treatment group (n=37) and control group (n=35). The control group received routine therapy, while the treatment group received ESW in addition, 2.0-4.0 bar, 10 Hz, 6000 times. They were evaluated with Harris Hip Score, Manual Muscle Test (MMT) and Short Form of health survey (SF-36) before and 1 month after treatment. Results The scores of Harris Hip Score and MMT improved more in the treatment group than in the control group (P<0.05) after treatment, as well as the scores of SF-36 except physical health and vitality (P<0.05). Conclusion The ESW can obviously improve the motor function and quality of life of patients with ANFH of stage IV.

Objective To observe the characteristics of the images of optical coherence tomography (OCT) performed on the patients with vitreomacular traction syndrome and its clinical significance. Methods The clinical data of 25 patients with vitreomacular traction syndrome diagnosed by OCT, fundus fluorescein angiography, and B-scan ultrasonography and confirmed by surgical treatment were retrospectively analyzed. The features of images of OCT in vitreomacular traction syndrome were observed. Results Five types were found in the images of OCT in the patients with vetreomacular traction syndrome. The main characteristic of the images of OCT in the patients with vitreomacular traction was the highly reflective band of the vitreous posterior cortex inservion at fovea. In 25 patients, vitreomacular traction associated with macular edema was found in 10, macular hole in 3, macular epiretinal membrane in 6, retinoschisis in 1, and retinal detachment in 5. Conclusion OCT is a potential powerful toll for detecting and monitoring vitreomacular traction syndrome.

Objective Discussion transurethral holmium laser treatment of ureteral orifice cyst and stones efficacy and safety . Methods A retrospective analysis of 23 cases of transurethral holmium laser treatment in patients with ureteral orifice cysts and stones (minimally invasive group) and 11 cases of open surgical excision of the cyst and stone -treated patients (open group), two groups were compared operative time, blood loss , catheterization time, hospital stay, postoperative complication rate .Results Minimally invasive surgery patients time (20.0 ±5.6)min, blood loss (15.0 ±2.3)ml, ambulation time (10.0 ±2.5)h, catheterization time (2.3 ± 0.2)d, length of hospital stay (5.0 ±0.6)d; open group of patients were (90.0 ±10.3)min, (80.0 ±12.7)ml, (48.0 ±5.3)h, (7.0 ±1.1)d, (11.0 ±1.7)d, two groups of indicators differences were statistically significant ( P <0.05).Postoperative complica-tions occurred in patients with minimally invasive group was 8.6%, down from 45.4% in the control group, the difference was statisti-cally significant ( P <0.05).Conclusions Transurethral holmium laser treatment of ureteral orifice cysts and stones with less trau -ma, less bleeding, shorter operative time, rapid recovery, the advantages of the low rate of complications , treatment of ureteral orifice cysts and stones safe and effective method .

Objective To investigate the abilities of emotion recognition and social cognition in patients with idiopathic epilepsy and further explore the factors related to the impairments.Methods After 24-hour EEG monitoring,70 people with idiopathic epilepsy were administered with a neuropsychological battery for basic cognitive assessment and then were tested with the Eye Basic Emotion Discrimination Task (EBEDT) and the Eye Complex Emotion Discrimination Task (ECEDT).Results Compared with health controls,people with epilepsy got significantly lower score in recognizing happy (19.3±2.0 vs 19.9±0.2),angry (17.9±2.0 vs 18.9±1.0),sadness (18.1±2.3 vs 19.2±1.0),fear (16.4±1.9 vs 17.6±1.3),disgust (17.6±2.1 vs 18.6±1.2) and surprise (18.3±1.5 vs 19.1±1.1) (P＜0.05,respectively),as well as complex emotions ((23.3±4.2) vs (27.1±2.8),P＜0.05).There was no significant difference between the two groups in gender recognition (P＞0.05).Significant positive correlation was found between the total score of basic emotions and the mind reading (r=0.444,P=0.000) in the patient group.Correlation analysis revealed significant relation between the total correct number of emotion recognition and the level of anxiety,depression and the executive function in epilepsy group (P＜0.05,respectively).Significant associations were found between the ECEDT and the Digital Span test,the Stroop test,Beck Depression Index and Hamilton Anxiety Scale (P＜0.05,respectively).Conclusion People with epilepsy have general impairments of emotion recognition and theory of mind,the impairments may be associated with the state of mood disorder and the weakened executive function.

Objective To validate cystatin (Cys C)-based equations for evaluation of residual renal function (RRF) in patients on continuous ambulatory peritoneal dialysis (CAPD).Methods Fifty patients on CAPD from our department were enrolled in the study.Eight patients with residual urine volume ≤ 100 ml/d and 42 patients with residual urine volume ＞ 100 ml/d were enrolled into anuria group and non-anuric group respectively.The clinical and laboratory status of each group were compared and equations (Hoek' s,Yang' s and abbreviated MDRD equations) were validated in the non -anuric group by comparing with the arithmetic average of residual renal creatinine clearance rate and residual renal urea clearance rate which was considered as the golden standard for RRF.Results (1) Anuric group had significantly higher serum Cys C than the non-anuric group [(7.73±1.13) mg/L vs (6.46± 1.15) mg/L,t =2.39,P =0.02)].(2) RRF estimated by each equation was correlated well with measured RRF (r =0.56,0.56 and 0.39,all P ＜ 0.05).(3) Yang' s equation [0.10 ml· min1· (1.73 m2)-1]was least biased,followed by Hoek' s equation [-0.73 ml· min-1 · (1.73 m2) 1] and abbreviated MDRD equation [3.15 ml· min-1 · (1.73 m2)-1].(4) The precision of Yang' s equation was equivalent to that of Hoek' s equation and both of them were better than abbreviated MDRD equation [6.2 and 6.1 vs 8.4 ml· min-1 · (1.73 m2)-1].(5) 50％ accuracy according to Yang' s equation and Hoek' s equation revealed an elevated results in comparison to that according to abbreviated MDRD equation (59.5％ and 54.8％ vs 23.8％,respectively,all P ＜ 0.01).Conclusions Serum Cys C-based prediction equations are better than the abbreviated MDRD equation in bias,precision and 50％ accuracy.For patients undergoing CAPD,the use of Cys C-based equation to estimate RRF may be a clinically acceptable alternative.

The challenge of the emergence of drug-resistant influenza strains, which is caused by wide spread utilization of direct-acting antivirals (DAAs), accelerates the research and exploration towards host targeted agents. In contrast to DAAs targeting viral replication components, host targeted agents, which regulate host factors and pathways linked to viral replication, can interfere the replication of influenza. Additionally, the innate immune system is activated by influenza during the early stage of infection, so manipulating the innate immune response may prevent the viral infection. However, the excessive inflammatory response induced at the late phase of influenza infection would lead to severe tissue injures. Thus, it is very important to explore drugs with anti-inflammatory actions to suppress these immune imbalances and tissue injures. Here we overview the current progresses about host targets related to anti-influenza drugs.

Adipose-tissue mesenchymal stem cells, is one kind of multipotent stem cells, can differentiate into adipogenic, osteogenic, chondrogenic, myogenic cells and so on in vitro and in vivo. Human adipose tissue is plentiful, easily harvested in large quantity with little patient discomfort. Adipose-tissue derived mesenchymal stem cells may be an alternative stem cell source for mesenchymal tissue regeneration and engineering without ethical consideration of embryonic stem cells and severe pain resulted by bone marrow procurement. The research work on adipose-tissue mesenchymal stem cells and future clinical perspectives were reviewed.
