[Objective] To explore the anti - inflammatory mechanism of sinomenine, a monomer alkaloid from Caulis Sinomenii. [ Methods] In - vitro enzyme was applied to observe the effect of sinomenine on cyclooxygenase (COX) 1 and COX 2. [Results] Sinomenine at the concentration of 1 - 250 ?mol/L could inhibit the formation of PGE2 induced by COX 2 in a good dose - effect manner. [Conclusion] Sinomenine selectively inhibiting the activity of COX 2 may be the anti - inflammatory and anagesic mechanism of sinomenine with less gastrointestinal adverse effect.

Objective To explore effect of small dose of diuretics combined with Dahuangzhechong pill on testosterone, Cystatin C(CysC), leptin and β2 microglobulin(β2-MG) in serum in patients with chronic renal failure.Methods 69 cases of kidney disease patients were collected and divided into two groups.Testosterone, Cystatin C, leptin and β2 microglobulin in serum were compared before and after the treatment.The control group was given hydrochlorothiazide tablets, treatment group was given Dahuangzhechong pill based on the control group.All patients were treated for 3 months. Results After treatment, levels of testosterone elevated (P <0.05), CysC, leptin and β2 microglobulin decreased (P <0.05) in the two groups compared with before treatment;Compared with the control group , level of testosterone was higher (P<0.05), levels of CysC ,leptin and β2-MG were lower (P<0.05).Conclusion Low dose diuretics combined with Dahuang Zhechong pill has good effect in treatment of chronic renal failure curative.The mechanism may be related to elevate serum testosterone levels and reduce serum CysC , leptin and β2-MG level in patients.

Manual Muscle Testing is a widely used muscle power testing method in rehabilitation practice. Although it's a key content in rehabilitation medicine and rehabilitation therapy, there are some disagreements in lots of books introducing the development and rating system of it. This article reviewed the development of Manual Muscle Testing and different rating systems.

The atlantoaxial articulation fracture or dislocation in children is one kind of common damage disease on upper cervical vertebra.Because the children are still in the stage of development,the atlantoaxial articulation ligamentum capsulare and the ligament are relax,so they are easy to be dislocated by external forces or be spontaneous dislocated caused by pathology reasons.The upper cervical vertebra damages on the children are quite different from that on the adults both in anatomical view and in biological term,therefore,the treatment are different from adults either.The treatments can be divided into the conservative ones and the surgery ones,the surgery treatment can also be divided into the posterior atlantoaxial fixed fusion technology,the occipitocervical fixed fusion technology and the odontid screw pexia.No matter using the conservative treatments or the surgical operation treatments,the root cure for the atlantoaxial articulation fracture or dislocation is to re-construct the stability of the articulation.The key point of freatment selection is to grasp the indications of each method.

BACKGROUND: Patellar tendinopathy is tiny damage at tendon insertion. Changes in the strength balance between vastus medialis and vastus lateralis in the quadriceps may lead to patellar abnormal motion, even an impact to the tendon insertion. OBJECTIVE: To analyze the mechanism and influence of patellar tendinopathy on the knee joint and surrounding muscles motion. METHODS: Ten male athletes with patellar tendinopathy and ten male athletes with matched sports item, body height and age were selected, and the knee-joint strength and surface electromyography were tested using CON-TREX Isokinetic Measurement System. The change of knee-joint flexor peak torque, extensor peak torque and surface electromyography of the quadriceps were compared with and analyzed. RESULTS AND CONCLUSION: Result showed during isometric exercise, extensor peak torque of the patellar tendinopathy group was significantly lower than the control group, and ratio of flexor peak torque to extensor peak torque was significantly higher than the control group; during isokinetic exercise, extensor peak torque of the patellar tendinopathy group was significant smaller than that of the control group, and notably changed with the increasing motion angular velocity; during isometric exercise and isokinetic exercise, the ratios of vastus medialis/vastus lateralis of the patellar tendinopathy group were lower than that of the control group. There were significant differences between knee-joint flexor and extensor of patellar tendinopathy athlete. The activity of vastus lateralis is low and vastus medialis and vastus lateralis are not in balance.

[Objective]To apply interal fixation with new pterygo-shape titanium mesh cage in the treatment of degenarative cervical spondylosis.[Method]Twenty-seven patients of degenarative cervical spondylosis were reconstructed after vertecotomy with the cage including 19 cases of CDH,8 cases of OPLL,18 cases in male and 9 cases in female;single segment degenaration were 21 cases,double segment degenaration were 6 cases.All cases were excluded fracture,dislocate by X-ray and MRI preoperatly.[Result]All 27 patients were followed up for an average time of 10 months(from 6 to 14 months).The anverage time of bone graft fusion was 10 weeks.[Conclusion]The pterygo_shape titanium mesh cage can provide immediate biomechanical stability and prevent the mesh cage displace,subsidence,exodus after operation.The surgical procedure is simple,safety and without illic-bone graft,meanwhile can greatly relieve patients' economy burden.Then the internal fixation is elastic fixation,the bone fusion shows a satisfactory result.

Objective:To investigate the root length,number and the transverse shape of first maxillary molars using root sectioning technique. Methods:100 isolated first permanent maxillary molars from above 20 years old patients were collected. The roots were cross-sectioned in three parts(superior 1/3,middle 1/3 and apex 1/3) after measuring the length of roots. The transverse shape of root canals were observed under the stereomicroscope.The number and shape of root in three parts of roots were recorded. Results:The length of lingual root,MB and DB of the first maxillary molar is (13.82?1.51) mm;(13.06?1.12) mm and (11.64?0.85) mm respectively; complex degree of MB and DB of the first marxillar molar is very high. 51% double roots in superior 1/3 of MB were found. Above 50% dual roots in the middle 1/3and apex 1/3 in the mesiobuccal root of first maxillar molar were recorded. Conclusion:Root number and transverse configuration in MB and DB of first maxillary molar varied in different parts of roots; There may be double root canals in medium 1/3 and apex 1/3 in MB of first maxillary molar when one line type canal in superior 1/3 was found.

[Objective] To study the in-vitro biological activity of albiflorin R1 (AR1), a new monoterpene glycoside from Paeonia lactiflora,in counteracting cell proliferation. [Methods] Two kinds of human cancer cell strains (HeLa cells and K562 cells) and J774 macrophage cell strain were cultured in vitro to observe the effects of albiflorin Rl on cell proliferation. [Results] Albiflorin Rl could markedly inhibit the proliferation of J774 macrophages and also inhibit the proliferation of HeLa and K562 cell stains in vitro. [Conclusion] Albiflorin Rl may have an anti-neoplastic, anti-inflammatory and immunosuppressive activity.

Objective To determine the serum level of Visfatin, and observe the effect of short-term treatment of rosiglitazone on it in the patients with type 2 diabetes mellitus. Methods Thirty-three patients with type 2 diahetes mellitus(diabetic group) who were inadequately controlled by suffonylureas were treated with rosiglitazone (4 mg/d) for 12 weeks. Twenty-seven sex-, age- and BMI-matehed non-diabetic subjects (control group) were studied. Determined blood pressure, Visfatin, triglyceride (TG), high density lipopro-tein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), fasting plasma glucose (FPG),2-hoar postprandial glucose (2 h PPG), fasting insulin (FINS)in all subjects and free fatty acid (FFA), high sensitive C-reactlve protein (hs-CRP) and glyeosylated hemoglobin (GHbA1c), abdominal fat distribution before and after treatment with rosiglitazone in diabetic group respectively. Results The level of serum Visfatin was lower in diabetic group than that in control group [(24.53±9.22) μg/L vs (53.10±27.00)μg/L, P<0.01 ], and it was higher after treatment with rosiglitazone for 12 weeks, but there was no significant difference [(24.53±9.22)μg/L vs (32.62±24.89) μg/L, P>0.05]. Visfatin was correlated significantly with systolic pressure (r =-0.29, P=0.02), FPG (r=-0.40, P=0.001 ), 2 h PPG (r=-0.34, P=0.009 ),LDL-C (r=0.26,P=0.049) and FFA (r=0.44,P=0.009) respectively. In a linear stepwise regression analysis, FFA showed significant correlation with serum Visfatin levels (r2=0.30,f=7.707, P=0.009).Conclusions The level of serum Visfatin is lower in type 2 diabetes mellitus, and it is related significantly with glucose and lipid metabolic factors. The short-term treatment with rosiglitazone can't increase the serum concentration of Visfatin in the type 2 diabetes mellitua.
