ObjectiveTo evaluate the effectivenes of continous passive motion(CPM) on limb function in patients after total knee arthroplasty.MethodsThe Cochrane Database of Systematic Reviews, MEDLINE, EMBASE, PEDro, CNKI and VIP were retrieved from the date of establishment of the databases to July, 2010 to collect randomized controlled trials(RCTs). The quality of RCTs was critically appraised and data were extracted by 4 reviewers independently. Meta-analysis was conducted for the eligible RCTs.Results26 RCTs were included. The result of Meta-analysis showed that CPM improved the range of motion (ROM) in active knee flexion and passive knee flexion, eliminate swelling in short term(＜6 weeks) and alleviate pain in short and medium term (less than 6 months). CPM showed no significant difference in improving the ROM in active and passive knee extention and quadriceps strength, and shortening hospital stay.ConclusionThe patients carried out CPM training after total knee arthroplasty can effectively improve limb flexion function, eliminate joint swelling, and relieve pain in the short term. But more high-quality and large-scale RCTs are needed.

OBJECTIVETo observe the effect of Tetramethyl pyrazine (TMP) on the cytokines and inflammatory mediators in the serum and the synovial fluid of collagen-induced arthritis (CIA)rats, and further to investigate its possible mechanisms for treating rheumatoid arthritis (RA).

METHODSType II CIA rat model was established. Rats in the TMP group were administered with TMP at 50 mg/kg and 100 mg/kg, once daily. Dexamethasone at 2.0 mg/kg was intramuscularly injected to those in the Dexamethasone treated group, once daily. Normal saline at 2 mL/kg was given to those in the normal control group and the model group, once daily. All medication was started from the 7th day, lasting to the 35th day. CIA rats' foot swelling degree was observed. Contents of serum IL-1, IL-6, IL-2, NO and PGE2in the synovial fluid were detected by radioimmunoassay and nitrate reduction method.

RESULTSCompared with the normal group, the foot swelling obviously increased, contents of NO and PGE2 in the synovial fluid were obviously elevated in the model group (P < 0.01). Compared with the model group, the foot swelling could be obviously inhibited by 100 mg/kg TMP and Dexamethasone; serum levels of IL-1 and IL-6 obviously decreased, serum IL-2 level obviously increased, contents of NO and PGE, decreased (P < 0.01). TMP 50 mg/kg could obviously inhibit the foot swelling of CIA rats (P < 0.01). There was no statistical difference in other indices (P > 0.05).

CONCLUSIONSTMP at 100 mg/kg showed obvious inhibition on CIA rats. Its inhibitory effect might be correlated to inhibiting activities of endogenous cytokines and the generation of inflammatory mediators in inflammation local regions, improving contents of anti-inflammation cytokines, and inducing the balance of the inflammatory cytokine network.

OBJECTIVETo observe the effect of nourishing Yin, strengthening Qi and activating blood decoction on Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression.

METHODThirty-two NOD mice were randomly divided into the model group, the traditional Chinese medicine group (TCM group, orally given 0.4 mL nourishing Yin, strengthening Qi and activating blood decoction as per 100 g x kg(-1) everyday), the hydroxychloroquine group (given 0.4 mL hydroxychloroquine as per 60 mg x kg(-1) everyday), the traditional Chinese medicine and western medicine group (TCM WM group, given nourishing Yin, Strengthening Qi and activating blood decoction 50 g x kg(-1) and hydroxychloroquine 60 mg x kg(-1), 0.4 mL everyday), with eight mice in each group. Eight Balb/C mice were selected as the normal control group (normal group). All of mice were killed after eight weeks, and their submaxillary glands were dissected. The expression levels of Fas/FasL were examined by immunohistochemical method, and the FasL mRNA was detected by RT-PCR.

RESULTThe expression levels of Fas/FasL in salivary glands of the model group were higher than that of other groups (P < 0.05). The expression level of FasL of the normal group was much lower than that in the hydroxychloroquine group (P < 0.05). The relative expression level of Fas mRNA in salivary glands of the model group was higher than that in other groups, but the control group was notably lower than other groups (P < 0.05). The expression level of FasL mRNA in salivary glands of the model group was higher than that in TCM and TCM WM groups (P < 0.05). But the expression level in TCM WM group was notably lower than the hydroxychloroquine group (P < 0.05).

CONCLUSIONThe nourishing Yin, strengthening Qi and activating blood decoction could down-regulate the expression level of Fas/FasL in salivary glands of NOD mice with Sjogren's syndrome and their mRNA expression, and had a better efficacy after being combined with hydroxychloroquine. The nourishing Yin, strengthening Qi and activating blood decoction might treat the Sjogren's Syndrome by reducing apoptosis which is regulated by Fas/FasL

Objective To test serum differentially expressed proteins between early-stage (stage IB-ⅢA) and late-stage (stage Ⅳ) lung cancer patients by proteinchip technology and investigate its clinical value. Methods SELDI-TOF-MS and WCX-2 protein chip were used to detect the serum protein of 30 cases of early stage lung cancer patients and 30 cases of late stage lung cancer patients. The data were analyzed by using Biomarker Wizard software. Results There are ten different proteins in the serum between the two groups of lung cancer patients. Four protein markers 7978, 8139, 15 951 and 16 133 are over expressed and seven protein markers 2867, 6885, 8701, 8840, 13 781 and 13 955 are low expressed in the late group. Conclusion SELDI-TOF-MS proteinchip technology is a convenient, sensitive and high-throughput analysis method which can screen several relatively specific protein markers for late stage lung cancer from the serum samples. This selected protein markers can predict metastasis of lung cancer patients.

Purpose To investigate the expression and significance of androgen receptor (AR) in breast carcinoma with different ER and PR status.Methods Immunohistochemical method was used to detect AR, ER and PR expression in 173 cases of breast carcinoma, and all the cases were grouped according to: (1) AR status: AR~- positive subgroup and AR~- negative subgroup, (2) ER status: En subgroup (negative for both ER and PR), Ep subgroup (positive for ER and/or PR), (3)AR, ER and PR status: En-AR~+ subgroup (AR~- positive cases of En subgroup), En-AR~- subgroup (AR~-negative cases of En subgroup), Ep-AR~+ subgroup (AR~- positive cases of Ep subgroup), and Ep-AR~- subgroup (AR~-negative cases of Ep subgroup).En-AR~- subgroup also was called negativE-for-all subgroup, and the rest three subgroups were called partly-or-completely positive subgroup (positive for at least one of the three markers), and then, the groups were compared with clinicopathological features.Results The positive rate of AR was 62.8% (54/86) in Ep subgroup and 37.9%(33/87) in En subgroup, and there was significant difference between them (P=0.001).Compared to AR~-negative subgroup, AR~-positive subgroup had smaller tumor size, less mitosis count and lower grade(P<0.05).Compared to the other three subgroups, En-AR~- subgroup had more mitosis count and higher grade (P<0.01).In En subgroup,AR~- positive cases had less mitosis count and lower grade (P<0.05), and in Ep subgroup,AR~- positive cases had higher stage(P=0.000), but no significant difference were found among partly or completely positive subgroups.Conclusions The expression of AR may play a different role in breast carcinoma with different ER and PR status, because it indicates good prognosis in negative for both ER and PR subgroup, but bad in ER and/or PR positive subgroup. When choosing a personalized therapy, all the combinations of hormone receptor status should be considered for the patients.

OBJECTIVE: To establish an HPLC method for the determination of the contents of the related substances in metoclopramide.METHODS: The sample was separated on C18 column with the mobile phase consisted of acetonitrile-0.02 mol?L-1 phosphonic acid solution(19∶81) at a flow rate of 1.0 mL?min-1.The detection wavelength was set at 275 nm;the column temperature was kept under room temperature and the injected volume was 20 ?L.The contents of the related substances in metoclopramide were computed by self-control method of main constituent.RESULTS: Under the above described chromatographic conditions,metoclopramide was completely separated from its impurities.A good linearity between impurities' peak area and metoclopramide(contrast solution) concentration was achieved when the concentrations of impurities were over the range of 0.05%～4.0%.The lowest detectable limit of metoclopramide was 0.3 ng,and the contents of the related substances were all less than 0.26%.CONCLUSION: The method is convenient,accurate,sensitive and,specific,and it can be used for the determination of the related substances in metoclopramide.

Objective To detect and analyze thyroid tumor by two-dimensional sonogram and Doppler parameter, and evaluate the value of high-frequency ultrasound in diagnosing thyroid benign and malignant tumors. Methods The ultrasonic images of 104 thyroid tumor from 80 patients with typical features were collected. Thyroid tumor was classified into benign and malignant nodules, based on the shape, border, or the rear wall echo, echo attenuation loss, internal echo, and microcalcifications in two-dimensional sonogram and systolic blood peak velocity (Vmax) and resistant index (RI) in Doppler examination. The expected results of high frequency ultrasound were compared with pathological results on consistency and error rate. Results Prediction of benign tumor by high frequency ultrasound was 66, and pathology 61, consistency rate of the two was 92.4%. Prediction of malignant lesions was 38, and pathological examination 32, consistency rate of the two was 84.2%. The total coincidence rate was 89.4%(93/104) and the error rate was 11.6%( 11/104). Conclusions The typical features of thyroid tumor on high-frequency ultrasound are helpful in diagnosis of benign or malignant nodules, which is valuable in guiding clinical treatment.

AIM:To explore relationship between the normal strehl ratio ( SR ) values of total aberrations/SR values of total higher-order aberrations and modulation transfer function ( MTF ) at total corneal at different pupil diameters in normal population.
METHODS: To exam the SR values of total aberrations and SR values of total higher-order aberrations of total corneals in 200 people ( 400 eyes ) using SIRIUS 3D topography system and analysis the corresponding root-mean-square ( RMS) .
RESULTS: The subjects with different pupil diameters (3. 0, 5. 0, 6. 0, 7. 0mm)'s exam results of total corneal were as following:SR value of total aberrations 100’(0. 45±0. 12), (0. 25±0. 06), (0. 17±0. 05), (0. 13±0. 04); SR value of total higher order ab cerrations 100’(0. 69±0. 14), (0. 34±0. 07), (0. 24±0. 05), (0. 16±0. 04);SR value of total aberrations 200’(0. 45±0. 12), (0. 24±0. 06), (0. 20±0. 04), (0. 16±0. 03); SR value of total higher order aberrations 200’(0.70±0. 13), (0. 35±0. 07), (0. 27±0. 06), (0. 20±0.04 ) . The SR values of each group decreases with the increases of pupil diameters. The SR values of total aberrations and SR values of total higher - order aberrations at total corneals are negatively correlated with corresponding RMS value. When the pupil diameter is small, the SR value of total aberrations is more related to higher frequency region of MTF. When the pupil diameter is big, the SR value of total aberrations is more related to lower frequency region of MTF.
CONCLUSION: The visual performance of normal people can be well reflected by SR values of total aberrations and SR values of total higher - order aberrations at total corneal.
