Objective To investigate the effects of sensorimotor therapy on patients with knee osteoarthritis.Methods Ninety-two patients with knee osteoarthritis were divided into a treatment group and a control group by using random digits table. Both groups received conventional rehabilitation therapy, including knee isometric and isotonic contraction training, ultrashort wave diathermy as well as aerobic exercise. The treatment group was also administered with sensorimotor training, in addition to the conventional training,including the muscle strengthening and control training of quadriceps and hamstring muscle using sling exercise therapy system and on the Thera-band mattress. The visual analogue scale (VAS) for pain, manual muscle testing and knee range of motion as well as the Japanese Orthopedic Association knee function evaluation form were used to evaluate the patients. Results There was no statistic difference between the 2 groups before treatment, with regard to the evaluation parameters used in this study. After 2 months of treatment, both groups improved significantly (P <0.05),with the treatment group improved to a significantly greater extent (P <0.05). Conclusions Sensorimotor training in addition to the conventional rehabilitation treatment can further relieve the pain of patients with knee osteoarthritis joints arthritis and improve the function of patients with knee osteoarthritis.

AIM: To systemically evaluate the clinical efficacy and safety of intraocular implants for vitreous retinal surgery.METHODS: We performed a comprehensive search for studies reporting vitreous surgery with intraocular implants randomized controlled and a retrospective controlled clinical trials from China Hownet ( CNKI ), Wanfang database, and VIP literature database. Studies obtained from those database were filtered according to the criteria, and data were retrieved from eligible studies for further analysis. Then we performed a meta-analysis to evaluate the efficacy and safety of intraocular implants using comprehensive Meta - analysis software version 2 (Biostat, Englewood, NJ).
RESULTS: In total 36 studies were recruited for our Meta - analysis, including 5 092 cases. Meta analysis showed: 1) regarding the efficacy of repairing the retinal detachment, silicone oil was a better intraocular implants than C3 F8(OR= 1. 76; 95% CI: 1. 19-2. 60, P = 0. 0047) and SF6( OR = 4. 68; 95% CI: 1. 48 - 14. 81, P = 0. 0087); 2) regarding the risk of postoperative cataract, silicone oil showed significant higher risk than BBS (OR = 3. 24; 95%CI: 2. 10-4. 99, P= 1. 09 e-7), and C3 F8(OR= 3. 03; 95% CI:1. 50 - 6. 10, P = 0. 0019 ); 3 ) regarding the risk of postoperative intraocular pressure, silicone oil showed significant higher risk than BBS (OR= 6. 74; 95% CI: 3. 38-13. 41, P= 5. 67 e-08), and C3 F8 also showed a higher risk than BBS (OR= 4. 79; 95% CI: 2. 37-9. 68, P = 1. 29 e-05). In addition, silicone oil showed significant lower risk as compared with heavy silicone oil (OR= 0. 16; 95% CI: 0. 08-0. 53, P= 0. 0026).
CONCLUSION: The intraocular implants for the treatment of retinal detachment in vitreous retinal surgery are mainly divided into two major categories, liquid and gas implants. The silicone oil, a major liquid implant, shows higher efficacy in terms of treating retinal detachment than the gas implants. However, the silicone oil is associated with a higher risk of postoperative cataract and intraocular pressure as compared with gas implants.

Objective To investigate the value of urine liver?type fatty acid?binding proteins(L?FABP) for early diagnosis and progress predicting of acute kidney injury(AKI)after lung transplantation. Methods Urine L?FABP and Scr blood samples in perioperative periods of 119 lung transplant recipients (hospitalized between 2013?2014)were involved in the research. Patients were divided into AKI group and non?AKI group according to KDIGO. Changes in urine L?FABP and Scr of two groups at various time points were recorded. Results Of 119 patients,57 developed AKI after surgery. Urine L?FABP from 0 h to 48 h in the two groups increased significantly, and the difference at 6 h to 48 h between the two groups is significant. In terms of diagnostic value,ROC area of urine L?FABP at 6h is 0.818. When 2254.52 ng/mg Cr was taken as diagnostic dividing line ,sensitivity and specificity was 0.782 and 0.814. In predicting AKI progression ,AUC below AUC of urine L?FABP 0.852. When 4313.17 ng/mgCr was taken as diagnostic dividing line ,sensitivity and specificity was 0.867 and 0.700. Conclusion Urinary L?FABP appears to be a sensitive and specific marker of AKI in lung transplant recipients ,could be a biological marker in the early diagnosis and progression tendency of AKI.

Chinese Pharmaceutical Journal 2016;51(5):391-395
OBJECTIVE: To prepare pyridostigmine bromide-phospholipids complex nanoemulsion (PPNE) and carry out in vitro and in vivo evaluation. METHODS: The pyridostigmine bromide-phospholipids and PPNE were prepared by solvent evaporation method and pseudo-ternary phase diagram method, respectively. The morphology, particle size, Zeta potential, in vitro release and oral bioavailability of PPNE were evaluated. RESULTS: The PPNE was approximately circular. The particle size and Zeta potential were 26.16 nm and -3.88 mV, respectively. The in vitro release behavior of PPNE was similar to pyridostigmine bromide. The relative oral bioavailability of PPNE was 208.1% to pyridostigmine bromide. CONCLUSION: PPNE was successfully prepared with a simple and repeatable method, which may be a fundamental formulation for further research of pyridostigmine bromide.

Objective To study the tolerance to 188Re-1-hydroxy-1 ,1-ethylidene disodium phosphonate(HEDP) in patients with bone pain caused by osseous metastases. Methods Thirty-one patients(10with prostate cancer, 9 with breast cancer, 3 with lung cancer, 5 with liver cancer, 2 with rectal cancer, 1with esophageal cancer and 1 with renal cancer) received a single injection dose of 188Re-HEDP. The patients were divided into four groups according to the injection dose: 20 MBq/kg (6 patients), 30 MBq/kg(6 patients), 40 MBq/kg (9 patients), and 50 MBq/kg (10 patients). Haematological toxicity (WHO grading) of grade Ⅲ- Ⅳ was considered unacceptable. Vital signs and adverse effects after injection were recorded for 8 weeks. Blood counts were measured weekly during a period of 8 weeks. Biochemical parameters and electrocardiogram were assayed at week 4 and 8. Statistical analysis was performed for per-protocol (pp) population (t-test). Results Twenty-seven patients belonged to PP population with 5 in the group of 20 MBq/kg, 5 in the group of 30 MBq/kg, 8 in the group of 40 MBq/kg and 9 in the group of 50 MBq/kg.No obvious adverse effects and no significant change of vital signs, electrocardiogram, liver and renal function were found after injection. Alkaline phosphatase was slightly higher than baseline at week 4 and 8 after therapy, but the difference was not statistically significant. In the 20 MBq/kg group, reversible grade Ⅰ leucopenia was noted in 1 patient. In the 30 MBq/kg group, 2 patients showed reversible grade Ⅰ leucopenia including 1 alone with reversible grade Ⅲ thrombopenia. In the 40 MBq/kg group, reversible grade Ⅰ leucopenia and thrombopenia was observed in 1 patient and reversible grade Ⅱ leucopenia and thrombopenia in another patient. In the .50 MBq/kg group, 3 patients showed reversible grade Ⅱ leucopenia. The lowest level of thrombopenia was at week 4(143.5 × 109/L), leucopenia at week 6 (5.4 × 109/L) and anaemia at week 8(t = 3.1325, 3.3156, 3.4917, all P < 0. 05 compared with baseline). At week 8, the mean level of platelet and leucocyte recovered to baseline. "Bounce pain" was found in 2 of 27 patients (7.41%).Conclusions The dose of 20 MBq/kg, 30 MBq/kg, 40 MBq/kg or 50 MBq/kg of 188Re-HEDP do not cause significant side effects on cancer patients with bone metastases, though there is a tendency that the haematological toxicity may increase as the dose of 188Re-HEDP increases.
