OBJECTIVETo observe the impacts on the muscle strength in the patients of stroke-induced acroparalysis treated with Xunjingcuiqi needling technique.

METHODSOne hundred patients were randomized into a Xunjingcuiqi group and a routine acupuncture group, 50 cases in each group. In the routine acupuncture group, the routine acupuncture technique was adopted at the main acupoints, such as Shangxing (GV 23), Baihui (GV 20), Dicang (ST 4), Quchi (LI 11), Huantiao (GB 30) and Zusanli (ST 36), etc. In Xunjingcuiqi group, on the basis of the routine acupuncture technique, Xunjingcuiqi needling technique (pricking technique was quickly applied with the filiform needle along the running course of meridian to promote the conduction of meridian qi) was added. For the patients being hard to feel the needling sensation and with the muscle strength of 0 to 1 degree, Dongzhencuiqi technique was supplemented at shu-stream points of yang meridians (after qi arrival, the needling manipulation with limb movement was given to promote the conduction of meridian qi). The treatment was given once every day in the two groups. Ten treatments made one session. Three sessions of treatment were required. At the end of each session treatment, the muscle strength and clinical efficacy were assessed.

RESULTSIn the 1st, 2nd and 3rd sessions of treatment, 20, 24 and 36 cases achieved the 3 to 5 degrees muscle strength in Xunjingcuiqi group, respectively; and 6, 10 and 15 cases achieved the 3 to 5 degrees muscle strength in the routine acupuncture group. The differences were significant statistically in comparison of the two groups (P < 0.01, P < 0.05). The markably effective rates were 60.0% (30/50), 64.0% (32/50) and 70.0% (35/50) after the 1st, 2nd and 3rd sessions of treatment in Xunjingcuiqi group, respectively; and those were 38.0% (19/50), 44.0% (22/50) and 46.0% (23/50) in the routine acupuncture group, respectively. The differences were significant in the 1st and 3rd sessions of treatment between the two groups (both P < 0.05).

CONCLUSIONXunjingcuiqi needling technique combined with routine acupuncture achieves the apparent superior efficacy on acroparalysis induced by ischemic stroke as compared with the simple routine acupuncture. Xunjingcuiqi needling technique obviously improves muscle strength and shortens the duration of sickness.

BackgroundDry eye is a multi-factorial-induced tear film and ocular surface disorder.Immunoinflammation plays a key role in the pathogenesis of dry eye.As inhibitor of the cyclo-oxygenase pathway,nonsteroidal anti-inflammatory drugs play an anti-inflammatory and anti-hypersensitivity role,and it can be a potential treatment for dry eyes.ObjectiveThis study was to investigate the effectiveness of nonsteroidal anti-inflammatory drugs (0.1％topical pranoprofen) on moderate to severe dry eyes and its mechanism.MethodsThis was a small sample of randomized controlled clinical trial.Thirty right eyes of 30 patients with moderate to severe dry eyes were included in the study according to the diagnosis criteria and randomized into two groups.The patients of the trial group received topical administration of 0.1％ pranoprofen plus 0.1％ sodium hyaluronate,and those of the control group received the topical 0.1％ sodium hyaluronate only.Ocular surface inflammation index scores (OSDI) and ocular surface fluorescine staining (OSS) scores were measured under the slit lamp,and tear film break-up time (BUT),Schirmer Ⅰ test values were evaluated.The expression of human leucocyte antigen-DR (HLA-DR) and CD11b in conjunctiva epithelial cells were detected by impression cytology and flow cytometry (FCM).All the indexes were compared between the two groups before and after treatment.Informed consent was obtained from all patients.ResultsThere were no significant differences in terms of age and gender and their baseline values between the trial group and control group (t=0.412,P=0.684;x2=0.240,P=0.624),and so were all the indexes (P＞0.05).Compared with the control group,the OSDI,OSS scores and cells positive for HLA-DR were lowered but the BUT was delayed in the trial group on day 15 ( t=2.43,P=0.03;t=2.83,P=0.01;t=3.29,P=0.00;t=3.23,P=0.00 ).No significant differences were found in the Schirmer Ⅰ test value and CD11b expression between these two groups (t=0.17,P=0.87;t=0.28,P=0.79).The OSDI,OSS scores and BUT were significantly improved,and the number of cells positive for HLA-DR were reduced 15 days after administration of drugs in comparison with before treatment in the trial group ( t =12.30,10.70,6.10,7.92,P =0.00 ).However,there were no comparable alteration seen in these indexes before and after the usage of drugs in the control group ( P＞0.05).Positive correlations were found in HLADR expression with OSDI and OSS ( r =0.601,P =0.018 ; r =0.586,P =0.022 ) and a negative correlation in HLADR expression with BUT (r=-0.697,P=0.004) on day 15 in the trial group.ConclusionsTopical usage of 0.1％ pranoprofen is beneficial for remitting the ocular signs and symptoms in moderate to severe dry eyes.This study illustrates that topical usage of 0.1％ pranoprofen can down-regulate the expression of inflammatory markers in conjunctival epithelial cells.

OBJECTIVETo evaluate the effect of blood pressure on vascular endothelial function using echo-tracking (ET) technology.

METHODSThirty hypertensive (HP) patients, 30 subjects with high normal blood pressure (HN), and 30 normotensive control (NC) subjects were enrolled in this study. For each subject, conventional two-dimensional ultrasound was performed to measure the intima-media thickness (IMT), and an ET system was utilized to assess the carotid elasticity (Ep, β, AC, AI, and PWVβ).

RESULTSAs the blood pressure increased, IMT, Ep, β, AI, and PWVβ values all increased and AC value decreased. Before excluding the confounding factors, the difference in IMT, Ep, β, AC, AI, and PWVβ values were significant between the 3 groups. After excluding the confounding factors, only PWVβ value was significantly different between HN group and NC group; but between HP and NC group and between HP and HN group, the other parameters still showed significant differences. Systolic blood pressure had significant influences on IMT, Ep, AC, AI, and PWVβ values, diastolic blood pressure significantly affected AI value, and pulse pressure significantly affected Ep and β values.

CONCLUSIONHigh normal blood pressure has no obvious effects on vascular function, and blood pressure is an independent risk factor of vascular endothelial dysfunction only in the stage of early hypertention. In early atherosclerosis, systolic blood pressure is the most significant factors affecting vascular endothelial function, followed by pulse pressure and diastolic blood pressure.

OBJECTIVETo observe the efficacy on primary osteoporosis treated with spreading moxibustion for warming yang and activating blood circulation so as to provide the effective clinical therapeutic methods for osteoporosis.

METHODSSixty cases of primary osteoporosis were randomized into a spreading moxibustion group (30 cases) and a calcium tablet group (30 cases). In the calcium tablet group, caltrate was prescribed for oral administration, 600 mg per day. In the spreading moxibustion group, on the basis of the treatment as the calcium tablet group, the spreading moxibustion was applied at Dazhui (GV 14) to Yaoshu (GV 2) for warming yang and activating blood circulation. The duration of treatment was 12 weeks. Visual analogue scale (VAS) score, TCM clinical symptom score and bone mineral density (BMD) were observed and compared before and after treatment in the patients between the two groups.

RESULTSVAS scores were reduced apparently after treatment in the two groups (both P < 0.01) and the results in the spreading moxibustion group were obviously superior to that in the calcium tablet group (2.36 +/- 0.43 vs 4.52 +/- 0.35, P < 0.01). BMD were all increased in the two groups (P < 0.05, P < 0.01) and the results in the spreading moxibustion group were superior to those in the calcium tablet group (both P < 0.05). The total clinical effective rate was 86.67% (26/30) in the spreading moxibustion group, apparently better than 63.33% (19/30) in the calcium tablet group (P < 0.05). TCM clinical symptom scores after treatment were all reduced apparently in the two groups (both P < 0.01), and the result in the spreading moxibustion group was obviously superior to that in the calcium tablet group (4.72 +/- 1.90 vs 6.82 +/- 2.30, P < 0.01). The total effective rate of TCM symptoms was 93.33% (28/30) in the spreading moxibustion group, apparently better than 70.00% (21/30) in the calcium tablet group (P < 0.05).

CONCLUSIONThe combined therapy of spreading moxibustion for warming yang and activating blood circulation and the oral administration of caltrate apparently relieves pain and TCM clinical symptoms, improves BMD in the patients of osteoporosis and achieves definite clinical efficacy in the patients of osteoporosis.

Background The domestic and international researches discovered that many proteins and enzymes of the extracellular matrix (ECM) participate in the sclera remodeling by affecting the collagen typeⅠand fibronectin.Objective This study was to investigate the effect of matrixmetalloproteinase-2 (TIMP-2) on expression of collagen typeⅠand fibronectin of ECM in the posterior sclera by injecting liposomes containing tissue inhibitor of TIMP-2 gene into suprachoroidal space of the form-deprivation myopia in guinea pig.Methods Form-deprivation myopia was induced by translucent goggles in 36 clean guinea pig for 2 weeks.Then the animals were randomly assigned to TIMP-2 group,empty plasmid group,saline group and 12 for each group.Liposomes of 5μl containing TIMP-2 gene,empty plasmid and saline were suprachoroidally injected in the right eye respectively,and the left eyes without any treatment were used as self-control group.Other 12 matched guinea pigs only covered the right eyes through out the experimental duration as model control group.The guinea pigs were sacrificed and the posterior sclera tissue of the eyeballs were collected at 2,7 and 14 days after injection of drug.The expressions of collagen typeⅠmRNA and fibronectin mRNA were detected by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR).This study followed the Regulation for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results The expression level of collagen type Ⅰ mRNA in the posterior sclera of guinea pig was lower but that of fibronectin mRNA was higher in TIMP-2 group than self-control group,showing significant differences between them (P＜0.05).The expression level of collagen type Ⅰ mRNA in the posterior scleral tissue began to increase from the 2nd day after drug injection and was obviously elevated at the 7th day and then gradually decreased at the 14th day.However,the expression level of fibronectin mRNA in the posterior scleral tissue showed the opposite pattern.The expression levels of collagen typeⅠmRNA and fibronectin mRNA at the 7th after drug injection were significantly lower than that at the 2nd day or 14th day (P＜0.01).Conclusion Suprachoroidal injection of TIMP-2 in form-deprivation myopia could up-regulate the expression of collagen typeⅠmRNA and down-regulate the expression of fibronectin mRNA in the posterior scleral tissue.It may slow down the sclera remodeling of form-deprivation myopia in guinea pig in the early stage.

OBJECTIVETo explore the effect of combination therapy of tetramethylpyrazine (TMP) with methotrexate (MTX) on collagen induced arthritis (CIA) rats.

METHODSTotally 55 male SD rats were stratified by body weight. Nine of them were randomly recruited as the normal control group. The rest 46 were immunized with type II bovine collagen (C II) for establishing rheumatoid arthritis (RA) model. Forty successfully modeled rats were randomly divided into 4 groups according to swollen toe degree, i.e., the CIA group, the TMP group, the MTX group, and the TMP plus MTX group, 10 in each group. Rats in the MTX group were administered with MTX (1. 2 mg/kg) , once per week for 4 continuous weeks. Those in the TMP group were administered with 40 mg/kg TMP, once per day for 10 continuous days, and then discontinued for 7 successive days, and continued for another 10 successive days. Rats in the TMP plus MTX group were administered with a mixture of equal dose MTX and TMP, and when MTX was discontinue, TMP was administered according to the way in the TMP group. Equal volume of saline solution was given to rats in the normal control group and the CIA group. Clinical parameters including ankle width (mediolateral diameter) and hindpaw swelling were measured at day 0, 4, 11, 18, and 26 after treatment. Rats were sacrificed 28 days after treatment, their knee joints and ankle joints were collected for pathological analyses. Serum levels of IL-1β, IL-6, and IL-17A were detected by ELISA. Changes of fibrinogen (FIB) and platelet aggregation rate (PAg) were detected.

RESULTSCompared with the normal control group, the ankle width and hindpaw swelling increased significantly (P < 0.01), contents of FIB and PAg increased obviously (P < 0.05, P < 0.01), serum levels of IL-1β, IL-6, and IL-17 increased remarkably (P <0. 01) in the CIA group. Obvious cell proliferation, inflammatory cell infiltration, hyperemia and edema of synovial tissues could be seen. Pannus formed and immerged in cartilages, resulting in necrosis. Compared with the model group, changes of ankle width and hindpaw swelling were all alleviated in each medicated group (P <0. 05, P <0. 01). Of them, the effect was superior in the MTX group to that of the TMP group and the MTX plus TMP group (P < 0.05, P < 0.01). Contents of FIB, serum levels of IL-1β and IL-6 decreased significantly in the MTX group (P < 0.05). Contents of FIB, serum levels of IL-1β and IL-6 decreased significantly in the TMP group and the MTX plus TMP group (P < 0.05). Besides, serum levels of FIB and IL-6 were obviously lower in the MTX plus TMP group than in the TMP group and the MTX group (P < 0.01). Levels of PAg and IL-17A were more significantly lowered in the TMP group than in the MTX plus TMP group and the MTX group. Pathological changes could be alleviated in each medicated group, with the optimal effect obtained in the MTX plus TMP group.

CONCLUSIONCombination of TMP with MTX could significantly ameliorate inflammatory reactions and FIB contents of CIA rats.

OBJECTIVEA new pattern recognition method suitable for traditional Chinese patent medicine was established in this paper, which is named as the Dual index grade sequence pattern recognition.

METHODIn this method the quality gradation was defined mathematically relying on normal distribution. By this way samples can be clustered and classified depending on which quality gradation is wanted, and the grading samples quantitatively relative to quality can be performed simultaneously. Especially, the redundant information with respect to pattern recognition hiding in dual index sequences of samples can be removed effectively by applying the good grade sequences, which make the pattern recognition results accurate excellently. This approach possesses the advantages of both supervised classification and unsupervised cluster methods. Samples can be clustered and classified at the same time without any standard samples, and the operation is accomplished based on the good grade similar sequences themselves being as the classifying marks. Moreover, the subclasses in each class can be identified more subtly.

RESULTThe infrared fingerprint spectra of extracts of 27 kinds of Mingmu Dihuangwan pills and Zhibo Dihuangwan pills samples extracted with ethanol were analyzed with the method proposed in this paper. The results showed that these pills can be classified in their subclasses clearly, respectively.

CONCLUSIONThe Dual index grade sequence pattern recognition is a new and effective one for identifying complex biological products made from complex herbal medicines.
