Objective To observe the clinical effect of intra-articular injection of sodium hyaluronate combined with rehabilitation training in treatment of knee osteoarthritis, and their effects on β endorphin and substance P levels in plasma. Methods All 106 cases with knee osteoarthritis were divided into treatment group and control group. Treatment group were treated by intra-articular injection of sodium hyaluronate combined with rehabilitation training, and control group underwent rehabilitation training only. Knee joint function was evaluated using Lysholm scores before and six weeks after treatment, and at 3-month and 6-month follow-up. Meanwhile, the concentrations of β endorphin and substance P in plasma were tested in the two groups. Results Compared with pre- treatment, the Lysholm scores were obviously increased after 6-week treatment, at 3-month and 6-month follow-up in both groups, with more obvious increase in treatment versus control group (P＜0.01). The Lysholm scores were higher in treatment group than in control group (P＜0.01). The concentration of β endorphin in plasma was significantly increased, and the substance P concentration in plasma was decreased after treatment in both groups. There were also significant differences in concentrations of β endorphin and substance P in plasma between treatment group and control group (P＜0.01). Conclusions Intra-articular injection of sodium hyaluronate combined with rehabilitation training is effective in improving knee joint function in elderly patients, in relieving pain and in enhancing joint movement.

Objective To compare clinical effects between cilostazol(CLT)alone and cilostazol combined with pancreatic kininogenase(PK)on lower extremity arterial disease in diabetic patient(LEADDP).Methods Patients with LEADDP were randomly divided into 2 groups:single medication group or the control group(53 cases)and combination group or the treatment group(53 cases).Sugar-reducing medicines were given before and after treatment to keep a steady blood glucose level.The control group took CLT orally 100 mg each time,twice a day.Besides receiving the same dose of CLT,the treatment group took 120 tablet of PK on an empty stomach,three times a day,with the duration of 3 months.Clinical symptoms,ankle/brachial index(ABI),blood rheology,nailfold microcirculation,intimal medial thickness(IMT)and plaque thickness were compared between the 2 groups after treatment.Results Symptoms in both groups improved after treatment.ABI was elevated significantly compared to that before treatment(P<0.05)and the change was more obvious in combination group.The difference of ABI after treatment between the 2 groups had statistical significance(P<0.05).IMT of the right foot dorsal artery,and left and right posterior tibial artery increased significantly compared to that before treatment(P<0.05).Plaque thickness decreased compared to that before treatment(P<0.01)and the difference between before and after treatment in combination group was significantly greater than that in single medication group(P<0.05).Conclusion Cilostazol combined with pancreatic kininogenase has better clinical effects than cilostazol alone in treatment of patients with LEADDP.

Objective To have a general picture the history and existing problems of independent clinical labs in China, for the purpose of building a supervision mechanism for such novel clinical institutions-clinical labs. Methods By way of the nationwide network of clinical labs, ICLs in China were surveyed with written questionnaires and field check. Results ICLs have grown into a greater and diversified scale thanks to the development of China's economy and laboratory technology. However,such vulnerabilities as unbalanced staff ratio, full-range quality control bugs, cutthroat competition,asymmetrical information disclosure, and bio-safety have loomed large in the meantime. Conclsion It is time to formulate a stricter industry access system and appropriate regulatory modes; ICLs should take a good care of the "Four relations" in their development, and health regulators should play a tighter role in the "Four supervisions". All these aim at better sharing medical resources, and building a win-win environment for the people, hospitals and ICLs.
