Objective To evaluate the efficacy of minimally invasive percutaneous intervertebral disc approach for treatment of sympathetic cervical spondylosis. Methods Fifty?six patients diagnosed as having sympathetic cervical spondylosis from January 2009 to August 2014, aged 22-64 yr, with the dis?ease course ranged from 6 months to 15 yr and a follow?up period of 6 months, were enrolled in the study. The related minimally invasive approach was selected according to the height of the diseased intervertebral space. When the ratio of the height of diseased intervertebral space∕normal intervertebral space≤1∕3, per?cutaneous radiofrequency ablation was used ( groupⅠ, n=19); when the ratio within the range of 1∕3-2∕3, percutaneous laser disk decompression was used ( groupⅡ, n=12); when the ratio≥2∕3, low?tem?perature plasma radiofrequency ablation was used ( group Ⅲ, n=25) . Before operation, at 2 weeks after operation, and at 1, 3 and 6 months after operation, the sympathetic symptoms were evaluated using the 20?point score. At 2 weeks and 6 months after operation, the patients′ subjective satisfaction was assessed and graded ( excellent, good, medium and poor ) . Results All the patients were followed up for 6 months. The sympathetic symptom scores were significantly lower at each time point after operation in Ⅰand Ⅲ groups and at 2 weeks and 3 and 6 months after operation in group Ⅱ than those before operation
( P<0.05) . The excellent and good rate of patients′subjective satisfaction was 67.9% at 2 weeks after op?eration, and 76.8% in the last follow?up period at 6 months after operation. Conclusion The minimally invasive percutaneous intervertebral disc approach has a marked short?term effect on sympathetic cervical spondylosis.

Background Our previous study demonstrated that curcumin can induce the apoptosis of retinal pigment epithelial (RPE) cells and herein inhibit the proliferation of RPE cells,and it is proved that the intravitreous injection of 0.1mg curcumin has less adverse effect to ocular tissue, inferring a good applicative prospect in clinic. Objective The goal of this experiment was to evaluate the effectiveness of curcumin on the prevention and treatment of experimental proliferative vitreoretinopathy (PVR). Methods PVR models were induced by injection of 0.1ml RPE cells (containing 2×106 cells) into vitreous cavity in 40 eyes of 20 healthy and mature New Zealand albino rabbits.0. 1ml curcumin(0. 1 mg) was then injected into lateral eye of each model rabbit immediately following the injection of RPE cells,and the equal volume of normal saline solution containing 0. 5‰ DMSO was injected into the fellow eye of each model rabbit as controls. On 1,3,7,14,21 and 28 days after injection, the changes of cornea, aqueous humor, lens, vitreous and fundus were examined and recorded by slit lamp biomicroscope, indirect ophthalmoscope,fundus color camera and B-type ultrasonograph to evaluate the inflammatory response. The incidence rate of retinal detachment was calculated and compared between curcumin group and control group. Results The inflammatory reaction in anterior chamber and misty opacity in vitreous were found from 1 day through 3 days after injection, but no obvious proliferative strap and retinal detachment in all of the experimental eyes. On the 7th day after injection, inflammatory reaction was extinct in the anterior chamber of rabbit eyes, and proliferative strap occurred in 14 eyes(75% ) in the control group but only 2 eyes (10% ) in curcumin group,showing significant difference between these two groups (P<0. 01). No retinal detachment was seen in both the two groups. On 14,21 and 28 days after injection, the incidence rate of retinal detachment was 55% ,80% ,95% respectively in control group and that of curcumin group was 10% ,15% ,15% respectively,presenting considerably differences between two groups (P<0. 01, P<0. 01 ,P<0. 01 ). Conclusion Injection of curcumin into vitreous cavity can effectively inhibit the occurrence and development of PVR in rabbit.

OBJECTIVETo explore the character of inorganic elements in Asari Radix et Rhizoma (Xixin).
METHODThe contents of 53 inorganic elements in Xixin samples from different localities and species were determined by ICP-AES and ICP-MS. The statistical data were made using SAS.
RESULTThe result demonstrated that Xixin has the high contents of Fe, Cr, Li. It has been observed that the content of Cu and Pb of the samples are much higher than the standard level. The results of hierarchical cluster analysis revealed two groups which correspond with the species of the samples. No correlations between the contents of the inorganic elements and the localities of the samples were found. Some characteristic elements were displayed in some specific areas. The difference of the contents of the 53 inorganic elements between root and rhizome of Xixin was reported for the first time. The primary form of inorganic elements in Xixin has been studied for the first time. The result demonstrated that the extraction rate between different elements varied, with the average extraction rate of (22.25 +/- 24.96)%.

OBJECTIVETo optimize the therapeutic programs for periarthritis of shoulder treated with acupuncture, moxibustion and kinetohterapy with orthogonal design method adopted.
METHODSThe orthogonal design table of L8 (2(7)) hierarchical principle was used to randomly divide 192 patients of periarthritis of shoulder into 8 groups, 24 cases in each one. Separately, 4 factors and each different 2 levels were adopted in treatment, named acupuncture timing (factor A: A, acute stage, A2 adhesion stage), acupoint combination (factor B: B, local acupoints, B2 local acupoints and distal acupoints along meridians), filiform needling and warm needling therapy (factor C: C1 acupuncture with filiform needle, CZ acupuncture with filiform needle and warm needling therapy) and positive functional exercise (factor D: D1 without positive functional exercise, D2 with positive functional exercise). The treatment was given once a day, 10 treatments made one session and 2 sessions were required totally. The time points of observation were the point after 1 session of treatment and after 2 sessions of treatment. The short-form McGill pain questionnaire (MPQ) and shoulder joint motor disturbance score were adopted for evaluation.
RESULTSIn the orthogonal design analysis, taking the hierarchical factors into consideration, the age was considered as the main factor in the evaluation of shoulder pain and shoulder motor disturbance (P<0.01), and the shoulder function grade apparently impacted pain evaluation and the efficacy on shoulder motor disturbance (P<0.01). The best combination of 4 factors and 2 levels were A1B1CzD2 and A2BC2D2. SAS statistical analysis showed that at acute stage and adhesion stage, CZ Dz , meaning acupuncture with fifiform needling and warm needling therapy combined with positive functional exercise, is the main factor of the improvements of shoulder motor function (P<0.05).
CONCLUSIONFor periarthritis of shoulder at acute stage, the combined therapy of acupuncture at local acupoints, warm needling and positive functional exercise is adopted. At chronic stage, the combined therapy of acupuncture at local acupoints and distal acupoints, acupuncture with filiform needle and warm needling and positive functional exercise is the best program. Additionally, in clinical treatment, the patients' age, sex, shoulder joint function and duration of treatment should be considered comprehensively for the impacts on the efficacy.

The release behavior of single pellet was investigated by LC/MS/MS method with tamsulosin hydrochloride (TSH) as the model drug of the research and then the pellets were divided into four groups according to the drug loading. Comparison of dissolution profiles of each group and capsule were performed using f1 and f2 factor methods to study the difference and similarity. The release profiles of single pellet, each group and capsule were analyzed using principle component analysis (PCA). The particle system was built through Matlab to get the target release profile. The result of this research demonstrated the release behavior of single pellet correlated well with the drug loading. While the dissolution profile of capsule as a reference, the similarity factor of dissolution profiles of the lower drug loading groups were 62.2, 67.1, 53.9, respectively and, 43.3 for highest drug loading group. The particle systems with different pellet distribution and same release profiles were built through release behavior of single pellet. It is of significance to investigate the release behavior of single pellets for studying the release regularity of multiple-unit drug delivery system.
