Objective: To establish a method for simultaneously determination of five isoflavones (daidzein, daidzin, puerarin, mirificin, and 6″-O-xylosidepuerarin) in Pueraria Radix by single marker (QAMS), which is feasible and accurate. Methods: Puerarin was taken as internal standard substance to establish the relative correction factor (RCF) for quantitative analysis of multi-components with QAMS. Thus, the contents of mirificin, 6″-O-xylosidepuerarin, daidzin, and daidzein were calculated. The contents in 10 batches of samples were determined by external standard method and QAMS. The scientificalness and feasibility of the methods were evaluated by comparison of the quantitative results between external standard method and QAMS. Results: The reproducibility of RCF was perfect. The results calculated with QAMS were consistent with the results by the external standard method. Conclusion: QAMS is accurate and feasible to evaluate the quality of Pueraria Radix.

PurposeThe restriction of strain ratio (SR) in the diagnosis of thyroid malignant tumor are caused mainly because of disadvantages including low sensitivity, in this research the authors used different calculation methods of strain ratio based on the size of tumors, to explore the clinical application value of them on the differentiation of benign and malignant thyroid nodules.Materials and Methods Data of 336 patients with thyroid nodule (340 nodules) who underwent elasticity imaging and ultrasound-guided fine-needle aspiration were retrospective analyzed, with the pathology combined follow up acted as golden standards, fixed surface area assay and true surface area assay of strain ratio were compared on the differential diagnosis of benign and malignant thyroid nodules with various size.Results Among 340 thyroid nodules, there were 91 small nodules and 249 big nodules. Pathological results showed that 36 of 91 small nodules and 104 of 249 big nodules were malignant, while the others were benign. The true surface area assay was significantly better for the diagnosis of smaller thyroid nodules with longitudinal diameter and transverse diameter<8 mm with higher consistency with pathology (χ2=20.89,P<0.01), and fixed surface area assay is more suitable of thyroid nodules with longitudinal diameter and transverse diameter>8mm (χ2=57.08,P<0.01). The sensitivity, specificity and consistency for the diagnosis of malignant nodules of true surface area assay were 57.10%, 83.00% and 72.30% (Kappa=0.413), which were 73.60%, 85.00% and 72.30% (Kappa=0.590) in the fixed surface area assay, and 85.00%, 85.50% and 85.30% (Kappa=0.699) in the selective usage of two methods according to the tumor size, respectively.Conclusion The sensitivity is highest when using the two methods selectively according to the nodule size, with a better consistence rate with pathological results as well.

OBJECTIVE To study the relation between the occurrence of nosocomial infection(NI) and white blood cell(WBC) count in malignant tumor patients after chemotherapy.METHODS The occurrence of NI and leukopenia and application of granulocyte colony stimulating factor(G-CSF) in patients after chemotherapy from Jan 2003 to Jun 2004 was investigated and analyzed retrospectively.RESULTS Among 2 040 patients,8.87% developed NI,and case rate was 11.67%;among patients with WBC count

OBJECTIVE To investigate the role of several xenobiotic metabolism-associated CYP450 isoforms in the auto-activation of hepatic stellate cells(HSCs) invitro. METHODS HSCs were isolated from adult Wistar rats and cultured on plastic as an in vitroauto-activation model. Positive expression of α-smooth muscle actin(α-SMA)was used as an activated marker of HSCs and detected by immunocytochemical staining in HSCs cultured for 1,2,5 or 11 d. The expressions of CYP450 isoforms were analyzed by real-time RT-PCR in the HSCs. RESULTS The immunocytochemical stai-ning showed no α-SMA expression in HSCs cultured for 1 d,while its expression gradually increased during culture since day 2. ln terms of α-SMA expression,HSCs cultured for 1,2,5,and 11 d were classified as the quiescent,early,middle and later stages of activation,respectively. The RT-PCR results revealed that CYP1B1,CYP2B1/ 2,and CYP2E1 mRNA were expressed at high levels in the early stage of HSCs activation(at day 2),which were 2.1-,1.6-,and 23.9-fold those in the quiescent HSCs(day 1),respectively. Further study revealed that mRNA expressions of these up-regulated CYPs in the early stage of activation were diminished at the subsequent two stages. The levels of CYP1A1 and CYP1A2 mRNA decreased constantly throughtout the activation process. CONCLUSION Multiple xenobi-otic metabolism-associated CYP450 isoforms might be involved in the auto-activation of rat HSCs invitro.

OBJECTIVETo explore the correlation between hand and face-mouth, so as to provide nerve reflex basis for the theory "Hegu (LI 4) regulates face and mouth".

METHODSSeven hundred and sixty-three participants who met the inclusive criteria were divided into different age groups. The skin around participants' thenar eminence was gently scraped to be observed whether there was an involuntary movement around the face or mouth, which was palmomental reflex. The results of palmomental reflex were recorded.

RESULTSThe total occurrence rate of palmomental reflex was 46.26%. For those who were 0 to 1 years old, the palmomental reflex was all positive; for those who were 21 to 36 years old, the positive rate was 20.45%, which was the lowest; for those who were 65 to 85 years old, more than half of them were positive. The majority of those who were 0 to 2 years old were bilateral positive palmomental reflex, while the majority of those who were 65 to 85 years old were unilateral positive palmomental reflex.

CONCLUSIONThere is a certain connection between hand and face-mouth. The occurrence rate of palmomental reflex changes from high to low over age increasing, and then changes from low to high with the aging, presenting a "high-low-high" U-shaped curve, which is possible related to the growth and recession of nervous system.

This study was aimed to evaluate the clinical effect and safety of Chinese medicine treatment of lumbar disc herniation with qi-tonifying, stasis-resolving and kidney-tonifying method. The randomized con-trolled trial (RCT) was applied in the study to evaluate the clinical effect of qi-tonifying, stasis-resolving and kidney-tonifying method in the treatment of lumbar disc herniation . A total of 122 lumbar disc herniation pa-tients were randomly divided into the treatment group ( n = 61 ) and the control group ( n = 61 ) . Chinese medicine treatment with the qi-tonifying, stasis-resolving and kidney-tonifying method was applied in the treatment group . And Celecoxib and Methycobal were orally administered in the control group . Then , the VAS scores, JOA scores, Oswestry disability index (ODI) were recorded and analyzed pre-treatment, four weeks af-ter treatment and the twelfth week of follow-up in order to evaluate the clinical effect . Adverse reactions were also observed and recorded at the same time to give a comprehensive evaluation on its safety . The results showed that there were no significant differences between the treatment group and control group in the baseline data before treatment . Hence , data from two groups were comparable . Compared with pre-treatment , the VAS scores and ODI scores were obviously reduced in both groups after four-week treatment . The JOA scores were increased obviously ( P < 0 . 05 ) . There were no statistical differences on ODI scores and JOA scores between two groups . The VAS scores of the treatment group were obviously higher than the control group ( P < 0 . 05 ) . In the twelfth week of follow-up , the VAS scores , ODI scores and JOA scores had increasing tendency in
both groups . There were no statistical differences between two groups . There were no statistical differences on the total effective rate between two groups . In the treatment group , four patients received surgery , four cases lost to follow-up , and four cases with mild adverse event . In the control group , six patients received surgery , three cases lost to follow-up , and two cases with mild adverse event . It was concluded that the RCT of Chi-nese medicine treatment of lumbar disc herniation with q i-tonifying , stasis-resolving and kidney-tonifying method received same clinical effect as the combination of Celecoxib and Methycobal . The Chinese medicine treatment can effectively relieve pain degree of lumbar disc herniation , improve function of the lumbar vertebrae and improve the daily life and social activity ability of patients. The short-term follow-up effects were con-firmed . However , the long-term efficacy still requires further study .

OBJECTIVE:To explore the improvement effect of different polar parts of Sanye Chongcha on models rat with ul-cerative colitis(UC). METHODS:The total extract was obtained from Sanye Chongcha by extraction with 80% ethanol,and dis-persed in water,from which the extracts of corresponding parts were obtained after extraction successively with trichloromethane and ethyl acetate and drying. 60 rats were randomized into normal group,model group,positive group(sulfasalazine enteric-coated tablets,312.5 mg/kg),trichloromethane extraction part group(70 mg/kg),ethyl acetate extraction part group(35 mg/kg)and wa-ter extraction part group(320 mg/kg). The rats except for normal group received 2,4,6-trinitrobenzenesulfonic acid solution(TN-BS)to establish UC model. 24 h later,the rats in the drug administration groups were given corresponding drugs ig,while those in normal group and model group were given normal saline ig,once a day,for 14 consecutive days. For the rats,the pathological change of the colon tissue was observed,and the colon mucosa damage index(CMDI)was scored;the activity of superoxide dis-mutase(SOD)and the content of malondialdehyde(MDA)in serum were determined. RESULTS:Compared to normal group,the rats in model group had obvious UC-like lesion,higher CMDI,lower activity of SOD and higher content of MDA in serum(P<0.01). Compared to model group,the rats in the drug administration groups had the lesion which became less serious or improved and had lower CMDI score,among which those of the ethyl acetate extraction part group and the positive group demonstrated a sta-tistically significant difference(P<0.01);and the rats in the drug administration groups except for trichloromethane extraction part group had higher activity of SOD and lower content of MDA in serum,among which the activity of SOD of the ethyl acetate ex-traction part group and the activity of SOD and content of MDA of the positive group demonstrated a statistically significant differ-ence(P<0.05 or P<0.01). CONCLUSIONS:The ethyl acetate extraction part of Sanye Chongcha can reduce colonic lipid peroxi-dation and thus has obvious improvement effect on the rats with UC caused by TNBS.

Objective To explore the effectiveness of KAP-HBM-TTM(KHT)-based health management on patients with chronic diseases in community. Method From April 2014 to June 2015, 834 patients with chronic diseases living in Desheng Community were randomly sampled and assigned to the intervention group (n=423, and the control group n=411). The K-H-T mode was used for the intervention group, and the routine management mode was applied to the control group. Using self-made questionnaire we tested two groups of patients' knowledge, attitude and life-style behavior. Chi-square test was used for data analysis.
