The research on regulation rules of traditional Chinese medicine (TCM) syndrome was the core of TCM syndrome information. It was thought that the constitution identification which provided the technology for evaluating health status was one of the bases in drawing the curve of conditional standard of syndrome. It was fitted and analyzed by the curve of conditional evolution of syndrome through establishing the curve of conditional standard of TCM constitution theory. It was the key technology of realizing the dynamical evaluation of TCM clinical effect.

Objective To investigate the relationship between metabolic syndrome (MS) and early recurrence of benign prostatic hyperplasia (BPH) after prostatectomy in the elderly.Methods A total of 152 men aged 65 to 88 years with prostatectomy for more than 5 years were enrolled from August 2008 to March 2013.Blood pressure,body weight,body height,body mass index (BMI) and international prostate symptom score (IPSS) were detected.Levels of fasting blood glucose (FBG),triglyceride (TG),low-density lipoprotein cholesterol (LDL-C),high-density lipoprotein cholesterol (HDL-C),prostate specific antigen (PSA) and maximum urinary flow rate (Qmax) were determined.The correlation of MS-related parameters with prostate volume,IPSS and Qmax were evaluated.Results BPH recurrence rate was significantly higher in patients with MS than without MS (11/26 vs.27/126,x2=12.76,P＜0.001).PSA level,prostate volume and IPSS were significantly higher or larger in the MS group than in the non-MS group [(1.96±0.82)μg/L vs.(1.81±0.90)μg/L,(28.26±5.50) ml vs.(22.38±4.00)ml,(11.12±3.18)vs.(7.11±2.37),F=28.654,44.41,38.56,respectively,P＜0.001],while Qmax value was significantly lower in the MS group than in the non-MS group [(14.77±5.29) ml/s vs.(19.80±4.70) ml/s,F=59.48,P＜0.001].The liner regression analysis showed that in postprostatectomy recurrence group,PV and IPSS had significantly positive correlations with levels of FBG and TG,and BMI (P＜0.05),and had significantly positive correlations with BMI and FBG in non-recurrence group (P＜0.05),while Qmax had a significantly negative correlation with BMI,systolic blood pressure and FBG in the two groups (P＜0.05).Conclusions There is a significant relationship between MS and higher BPH recurrence in elderly patients.

Abundant experiences have already been accumulated in treatment of stroke with acupuncture. Development of rehabilitation theory also brings unprecedented opportunity and challenge to acupuncture. Combined with the modern rehabilitation theory and practice, it is very helpful to deepen the understanding on treatment of acupuncture for cerebral apoplexy and enhance the therapeutic effect in clinic by studying the mechanism of acupuncture treatment, opportunity of intervention, selection of acupoints, needling manipulations and quantity of stimulations etc. Through analysis on the necessity and the way of combination of acupuncture and modern rehabilitation, it is concluded that rehabilitation evaluation, rehabilitation phases and obstacle analysis should be taken as references by acupuncturists to reinforce the therapeutic effect and creditability of acupuncture treatment on cerebral apoplexy.

Objective To investigate the effects and mechanisms of 5-aza-2'-deoxycytidine (5-Aza-CdR) on endometrial cancer cell.Methods In vitro experiments of 5-Aza-CdR were done using human endometrial cancer cell line HEC-1B.Evaluation of cellular proliferation and apoptosis was ascertained respectively using trypan blue exclusion and flow cytometry.RT-PCR and methylation specific PCR(MSP) was done to detect the expression of RASSF1 A mRNA and methylation status of RASSF1 A promoter of HEC-1B cell line.Results (1) The status of cellular growth and apeptosis of HEC-1 B cell line:the growth inhibition effects of 5-Aza-CdR on HEC-1B cell line were both concentration-dependent (P ＜ 0.01) and time-dependent(P ＜0.01),as well as the apoptosis rate of HBC-1-B cell line depended on the dose of 5-Aza-CdR obviously(P ＜0.01).(2)The expression of RASSF1A mRNA of HEC-1B cell line:RASSF1A mRNA was expressed in HEC-1B cell after 5-Aza-CdR treatment,but it was undetectable before the treatment.In the groups with different concentration of 5-Aza-CdR (0.05,0.1,1,5,10 nmol/ml),the expression of RASSF1A mRNA was respectively 0.074±0.004,0.105±0.004,0.167±0.006,0.334±0.005,0.484±0.007,which were remarkably different from the group without 5-Aza-CdR(the expression of RASSF1A mRNA was 0;P ＜ 0.01).(3) The hypermethylation of RASSF1A promoter of HEC-1B cell line:the hypermethylation of RASSF1A promoter was detected in HEC-1B cell line.The status of hypermethylation was decreased after treatment with 5-Aza-CdR of 0.05,0.1,1,5 nmol/ml,meanwhile,both methylation bands and demethylation bands were observed by methylation specific PCR.After the treatment with 5-Aza-CdR of 10 nmol/ml the hypermethylation was absent absolutely.Conclusions (1) In HEC-1B cell line,5-Aza-CdR can inhibit cell proliferation and induce cell apopotosis.(2) 5-Aza-CdR can renew the expression of RASSF1A mRNA of HEC-1B cell line and reverse the hypermethylation of RASSF1A promoter.

Background Endophthalmitis is a serious infectious eye disease.Efficient drug therapy plays a key role in the early stage.There have been few researches on teicoplanin treating endophthalmitis and pharmacokinetics in ocular tissue.Objective The present study was to investigate the intraocular pharmacokinetic course and feature of intravitreal administration of teicoplanin.Methods Thirty-three Japanese white rabbits were included in this study and randomized into 6 groups.The right eyes of the rabbits were used in experiment.5 g/L of teicoplanin was injected into the vitreous cavity,and vitreous and aqueous humor samples were extracted after 15 minutes,30 minutes,1,2,4,6,12,24,48,96 and 192 hours,and the concentration of teicoplanin was determined by bioassay.Results The logarithmic value of the concentration of teicoplanin was raised with the increase in the bacterial inhibition zone diameters,of which the equation of the regression curve was Y =0.174X-0.813(R2=0.999).A good linear relationship was presented within 1.0-80.0 mg/L.Single intravitreal injection of teicoplanin was compliant with the two-compartment model.Moreover,the distribution phase Tα1/2 and elimination phase Tβ1/2 of vitreous were 1.68 and 152.15 hours,separately.And Tα1/2 and Tβ1/2 of the aqueous humor were 2.83 hours and 70.56 hours,individually.The peak teicoplanin concentrations in the vitreous and aqueous humor were(358.47±21.53)mg/L and(102.17±9.54)mg/L at 1 hour,respectively and remained at(4.38±0.68)mg/L and(2.38±0.38)mg/L,respectively 192 hours later.Conclusions Intravitreal injection of 0.5 mg of teicoplanin can remain therapeutic concentration for a long time in the vitreous and aqueous humor.

Objective To investigate the level of subpopulations of myeloid-derived suppressor cells (MDSCs) in elderly tumor-bearing mice versus elderly tumor-free mice,and to study the difference in immune suppressive functions between different subpopulations and their mechanisms.Methods A total of 20 healthy C57BL/6 elderly mice(aged 18-20 months) were randomly chosen to establish Lewis lung cancer models.The amount of monocytic-MDSCs (MO-MDSCs) and polymorphonuclear granulocytic-MDSCs(PMN-MDSCs) in tumor-free and tumor-bearing elderly mice was evaluated by using flow cytometry.MO-MDSCs and PMN-MDSCs were separated with Magnetic-Activated Cell Sorting (MACS) MicroBeads and their morphological characteristics were observed after May-Grunwald-Giemsa staining.The effects of MO-MDSCs and PMN-MDSCs on the proliferation of T cells were determined by Brdu-enzyme-linked immunosorbent assay(ELISA).And the immune suppressive mediators secreted by the subpopulations were detected by Real-time polymerase chain reaction(PCR).Results Compared to the tumor-free group,the proportion of MO-MDSCs in the spleen of tumorbearing group were increased [(12.44± 1.20) ％ vs.(38.42±3.66) ％,t=5.67,P＜0.001],while PMN-MDSCs were not [(10.34±0.68) ％ vs.(12.18±1.27) ％,t=2.21,P=0.09].The result of Brdu-ELISA showed that MO-MDSCs could suppress the proliferation of T cells [(0.30 ± 0.18) vs.(3.38±0.96),t=8.33,P＜0.001],while PMN MDSCs could not [(2.69±0.45)vs.(3.38±0.96),t =1.72,P=0.11].The result of PCR showed that as compared with PMN-MDSCs,Mo-MDSCs had the increased expression levels of arginase-1 (ARG-1),inducible nitric oxide synthase (iNOS),interleukin-10 (IL-10),interferon-γ(IFN-γ) (t =4.31,8.89,1.70,3.13,respectively,P ＜ 0.01 or 0.05),while the expression levels of interleukin-13 (IL-13),transforming growth factor-β(TGF-β) had no differences (t=4.94 and 2.75,P =0.39 and0.47).Conclusions MO-MDSCs are significantly increased in elderly Lewis lung cancer mice models.MO-MDSCs could mediate lung tumor evasion by suppressing the proliferation of T cells through highly expressing ARG-1,iNOS,IL-10 and IFN-γ.

Objective To investigate the influencing factors of 18F-FDG uptaking in head and neck malignancy by SPECT/CT coincidence imaging. Methods 18F-FDG SPECT/CT coincidence imaging was performed in 32 patients with head and neck malignancy after surgery, radiotherapy or radiotherapy + chemotherapy. The radio of target/no target (T/N) was calculated. The gender, age, fasting blood glucose level, size of tumor, location of tumor, pathological classification, de-gree of cell differentiation and treatment modalities were analyzed between groups. Results The single-factor analysis of variance showed that the T/N value was significantly higher in >70 yeas old, group than that of 41-50 yeas old group and 51-60 yeas old group (P<0.05). The T/N value was significantly lower in tumor size<2 cm group than that of 2-5 cm group and>5 cm group (P<0.05). And it was lower in poor differentiated tumor group than that of. undifferentiated tumor group (P<0.05). There were no significant differences in T/N values between other indicator groups (P>0.05). The multiple linear regression analysis showed that 18F-FDG uptaking in head and neck malignancy (T/N=Y) was related to the age of patients (X2), the diameter of tumor (X4) and the degree of cell differentiation (X9): =-4.389 25+0.053 03 X2+1.617 86 X4+0.718 35 X9. Conclusion Tumor recurrence is more likely to occur in patients with age>70 years old, the diameter of tumor≥2 cm, and the anaplastic head and neck malignancy.We should pay much attention to the diagnosis and follow-up for these pa-tients.

Background and purpose:At present, color Doppler ultrasound scoring and radionuclide imaging are two important imaging methods for diagnosing thyroid nodules, but their checking principle is different. Which method is better? Or combining them will be the best method for diagnosing thyroid nodules? This study aimed to compare the value of99mTcO4- combined with99mTc-methoxyisobutylisonitrile (MIBI) imaging, ultrasound scoring method and ultrasound scoring method+99mTcO4-+99mTc-MIBI imaging in diagnosis of thyroid nodules.Methods:The results of ultrasound scoring method and99mTcO4- combined with99mTc-MIBI imaging were compared in 50 patients with 54 thyroid nodules, and then compared with pathological findings. The sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of the methods were calculated.Results:A total of 54 thyroid nodules were found pathologically including 20 malignant and 34 benign nodules. The sensitivity, specificity, accuracy, PPV and NPV of99mTcO4- combined with99mTc-MIBI imaging were 80.00% (16/20), 70.59% (24/34), 74.07% (40/54), 61.54% (16/26), 85.71% (24/28), re-spectively. Those of ultrasound scoring method were 80.00% (16/20), 88.24% (30/34), 85.16% (46/54), 80.00% (16/20), 88.24% (30/34), respectively. And those of ultrasound scoring method+99mTcO4-+99mTc-MIBI imaging were 100.00% (20/20), 64.71% (22/34), 77.78% (42/54), 62.50% (20/32), 100.00% (22/22), respectively. The sensitivity of ultrasound scoring method+99mTcO4-+99mTc-MIBI imaging was higher than ultrasound scoring method or99mTcO4-+99mTc-MIBI imaging along (100.00%vs 80.00%, 100.00%vs 80.00%,χ2 value was 4.444 4 and 4.444 4,P value was 0.035 0 and 0.035 0, respectively). The specificity of ultrasound scoring method was higher than those of two methods combined together (88.24%vs 64.71%,χ2 value was 5.230 8,P value was 0.022 2). However, no factorial negative thyroid nodule was found by ul-trasound scoring method+99mTcO4-+99mTc-MIBI imaging.Conclusion:Ultrasound scoring method+99mTcO4-+99mTc-MIBI imaging can offer comprehensive diagnosis of thyroid nodules from their structure and function to avoid missed diagnosis.

Objective To observe the effects of repetitive transcranial magnetic stimulation (rTMS) combined with abdominal muscle electrical stimulation on the pulmonary ventilation of patients with cervical spinal cord injury.Methods Twenty-five patients with cervical spinal cord injury were randomized into an experimental group (n =13) and a control group (n =12).The control group was given comprehensive rehabilitation treatment,including upper limb movements,standing training and training of respiratory function,while the experimental group was given repetitive transcranial magnetic stimulation and abdominal muscle electrical stimulation in addition to the comprehensive rehabilitation treatment.The patients' maximum lung capacity (VC),forced expiratory volume for 1 second (FEV1),peak expiratory flow rate (PEF) and tidal volume (VT) were measured at the outset and after 3 months of treatment.Results The lung function indexes increased in both groups after treatment,but each index improved significantly more in the experimental group,on average,than in the control group.Conclusion As a supplement to routine respiratory function training,repetitive transcranial magnetic stimulation combined with abdominal intermediate frequency electrical stimulation can improve the pulmonary ventilation function of patients with middle and lower cervical spinal cord injury.
