Osteoarthritis is a common chronic degenerative disease, which is currently the main drug therapy.Hyaluronic acid (HA) is a kind of glycosaminoglycan in the interstitial cells, which has the character of viscoelasticity, lubricity, biocompatibility,biodegradability and anti-inflammatory. It is wide applicated in the treatment of osteoarthritis.However, the half-life of the common hyaluronic acid injected into the joint cavity is shorter, patients need frequent dosing and the compliance is poor, research on new uses of hyaluronic acid formulations and clinical pharmacy workers is the new direction of research.In this paper, the recent advance of HA on function, safety, effectivity and novel application in osteoarthritis therapy are summarized.

Objective To summarize the clinical experience of 38 cases of cardiac surgery with full sternotomy through minimal skin incision.Methods A total of 38 cases of selective cardiac surgery were performed from June 2004 to December 2005.The operation was conducted under full sternotomy through a skin mini-incision.Results The operation was successfully completed in all the 38 cases.The total operation time was 175~359 min(mean,84 min),the drainage volume was 110~760 ml(median,380 ml),and the postoperatine hospital stay,7~32 d(mean,10 d).Postoperative short-term complications included 1 case of arrhythmia and 2 cases of pyrexia,all of which were cured.No thoracotomy for hemostasis was required.The incision healed by first intention without infection or separation.Follow-up examinations for 3~18 months(mean,9 months) in 38 cases showed significat improrement of symptoms.The left ventricular ejection fraction after operation was 0.45~0.73(mean,0.62).Conclusions Full sternotomy through minimal skin incision for cardiac surgery is safe and micro-traumatic.This procedure provides advantages of simplicity of performance,no need of special surgical instruments,and good cosmetic outcomes.

Objective To evaluate serum TPSA and F/T ratio in the differential diagnosis of BPH and PCa. Methods Serum TPSA,FPSA and F/T ratio in 177 cases of BPH and 60 cases of PCa were assessed and evaluated both in patients within and outside the "gray zone". Results TPSA and F/T ratio were both significantly discriminating between benign and malignant diseases (0.010.05) whereas F/T ratio could ( P 0.05). Conclusions Serum TPSA is a prostate carcinoma marker,F/T ratio being an adjuvant marker of TPSA of importance on the differential diagnosis in patients within the "gray zone".

Objective To investigate the effect of rapid eye movement (REM) sleep deprivation on spatial memory and hippocampal cellular prion protein (PrPC) expression and to explore the underlying mechanism of cognitive impairment induced by sleep deprivation.Methods Adult Sprague-Dawley rats were sorted by weight,randomly divided into three groups:the cage control (CC) group,the tank control (TC) group,and the sleep deprivation (SD) group.Rats were deprived of REM sleep for 72 h using the modified multiple platform method.The Morris water maze task was used to assess hippocampal-dependent spatial memory.After sleep deprivation,the rats were sacrificed and their brain tissue was analyzed for PrPC protein expression via Western blotting.Hippocampal neuron axon elongation was examined as well after lentivector-mediated RNA interference (RNAi) of PrPC in primary cultured rat hippocampal neurons.Results REM sleep deprivation for 72 h resulted in spatial memory impairment.The number of times of rats passing through the platform was decreased significantly in the SD group (3.17 ±0.95) compared with the CC (7.17 ±0.95) and TC (6.50 ±0.62) groups (Z =2.026 6,Z =2.026 6,P <0.05),the mean value of proximity to the platform (mm) was greater for rats of the SD group (711.74 ± 33.99) compared to those of theCC (592.32±31.31) andTC (580.86±11.36) groups (Z=-2.001 6,Z=-2.4820,P < 0.05).REM sleep deprivation for 72 h resulted in reduced PrPC level in the hippocampus (0.33 ± 0.10) compared with the CC (1.01 ±0.33) and TC (0.96 ±0.27) groups (Z=2.152 9,Z=2.152 9,P < 0.05).In primary cultured hippocampal neurons,axon elongation(μm) was inhibited 7 days in infected neurons (326.28 ± 12.53) compared with normal (555.00 ±30.43) or negative control (558.70 ±23.10) cells (Z =4.768 4,Z =4.877 0,P < 0.05).Conclusion These findings suggest that PrPC-mediated hippocampal neuron axon elongation inhibition is probably involved in spatial memory impairment induced by sleep deprivation in rats.

Purpose:To evaluate the effect and toxicity of gemcitabine cisplatin combination in elderly patients with advanced NSCLC.Methods:32 elderly patients were treaded with Gemcitabine 1 000 mg/m 2 on day 1,8 and DDP 70 mg/m 2 on day 1. The second treatment cycle was given on day 22.Results:Each patient was given at least 2 cycle chemotherapy. All together 134 cycles were given. The overall response rate (the completed response plus partial response) was 43.8%. The main toxicity was bone marrow depression. The proportion of WHO grade 3 4 hemoglobin, leukocyte and thrombocyte decrease cycles was 7.5%, 12.7%, 23.1%, respectively.Conclusions:Gemcitabine cisplatin combination is effective and well tolerated for elderly patients with NSCLC.

Objective To evaluate the advantages and disadvantages of different puncture positions in percutaneous nephrolithotomy. Methods Three hundred fifty-six patients who underwent PCNL were analyzed from March 2012 to October 2015. The passage caliber was 16F-20F. There were 217 cases in prone position and 139 cases in supine position. Results The successful operation in PCNL was 354 cases , while the remaining 2 cases were performed by open surgery. The primary stone clearance rate was 75.5%. The additional PCNLs were performed in 23 cases, and 63 cases of residual calculi were treated by ESWL. 11 patients were treated due to infection or bleeding by the additional PCNLs. There were 3 cases with massive hemorrhage which were treated by Interventional embolization therapy , 12 cases in postoperative fever , no renal resection , no intestinal injury, no deaths. There was no significant difference in stone clearance rate and complication rate between the two groups. Conclusion The puncture position of PCNL can be optional based on the stone size , stone location, degree of hydronephrosis ,and patient′s cardiopulmonary condition individually.
