Chemokine receptor 5 (CCR5 ),as a member of the G protein-coupled receptor(GPCR)superfamily,is a membrane protein on cell surface and one of the major of coreceptors for HIV-1infection.CCR5 has became a molecular target for the novel drugs against HIV-1,and antagonists for CCR5 could be grouped as following, chemokine derivatives,small molecule non-peptide compounds,molecular antibodies and peptides. These compounds with high anti-viral activity and affinity are at different stages, and some have been under clinical studies. Therefore, the development research in the different kind of CCR5 antagonists is reviewed.

Methods:A total of 48 whole blood samples with platelet count less than 70×109/L were randomly collected from XN-9000 correlation analysis to evaluate XN-9000 the accuracy and precision of detection in low whole blood PLT and carry pollution rate, use XN-9000 and microscope count, respectively.Results: XN-9000 detection in low whole blood PLT between batch and batch of CV% 1.13% and 1.29%, respectively; XN-9000 with microscope PLT count results have high correlation, The regression equation forY=0.917X+3.217,correlation coefficientr=0.964; XN-9000 detection in low whole blood PLT carry pollution at a rate of 0.12%. Detection accuracy of PLT Bias, %(-1.25%~1.8%); Linear range(0~1206)×109/L; Clinical reportable range (0~6030)×109/L.Conclusion: The detection of XN-9000 blood analyzer is in low whole blood PLT has high precision and accuracy, carry pollution rate is extremely low, the result has the reliability, can be directly applied to clinical.

Objective:To observe the clinical efficacy of tuina with intensive stimulation at tender points plus medication in treating cervical intervertebral disc herniation (CIDH).
Methods:Totally 158 CIDH patients were randomized into an observation group and a control group by their visit sequence, 79 cases in each group. The control group was intervened by oral administration of Meloxicam tablets, 7.5 mg for each dose, once each day. The observation group was additionally intervened by tuina with intensive stimulation at tender points based on the treatment given to the control group, once each day. The therapeutic efficacy was evaluated after successive 14-day treatment for the two groups.
Results:The total effective rate was 92.4% in the observation group, significantly higher than 81.0% in the control group (P<0.05). The visual analogue scale (VAS) scores dropped significantly after the treatment in both groups (bothP<0.01), and the VAS score of the observation group was significantly lower than that of the control group (P<0.01).
Conclusion:Tuina with intensive stimulation at tender points plus oral administration of Meloxicam tablets can produce a more significant efficacy in treating CIDH than taking Meloxicam alone, thus worth promoting in clinic.

Objective To explore the electrophysiological and clinical features of various subtypes of Guillain Barr? syndrome (GBS). Methods The electrophysiological and clinical data of 100 cases with GBS admitted to Xijing Hospital from 1980 to 1999 were analyzed retrospectively. Correlations between varied subtypes and ages were examined by ? 2 test. Results Among the 100 patients with GBS, the demyelinating pattern was present in 51 patients, the axonal pattern in 25 patients, and 8 patients were inexcitable, 12 patients equivocal and 4 patients normal. The demyelinating pattern appeared as a major subtype not only in different age groups, but also in different test times after symptom onset. There was no statistically significant relationship between varied subtypes and ages. In the 100 patients, 32.0% suffered from a preceding upper respiratory infection, and 22.0% had a preceding gastrointestinal tract infection. The cases occurring in rural areas are almost in number equal to those in urban areas. That is, there was no a clear area distribution. Both demylinating and axonal GBS occurred throughout the year with a likely peak from July to September. Conclusion In the 100 patients with GBS admitted to Xijing Hospital, the demyelinating pattern was the major electrophysiological subtype. In addition, the electrophysiological and clinical features of various subtypes of GBS seemed to be different in some ways from those in the studies of both western countries and Li CY in northern China.

Objective To make up an exercise prescription based on traditional Chinese medical training (EP-TCMT) for patients with stable chronic obstructive pulmonary disease (COPD).Methods Eighty-five pa- tients with stable COPD were randomly divided into a control group (CG group),a traditional Chinese medicine group ( TC group) and an exercise prescription group ( EP group).The patients in the TC and EP groups were giv- en intensive training for 8 weeks.Their 6 rain walk distance (6MWD) and Borg scale scores were assessed before and after the treatment.Results The 6MWD in the TC group increased from 337.68?59.18 m to 386.14?76.71 m,while those in the EP group improved from 348.00?55.94 m to 425.17?53.22 m.The Borg scale scores in the TC group decreased from 3.14?1.94 to 2.32?1.25,while those in the EP group declined from 3.45?1.84 to 1.72?0.70.Conclusion Making up EP-TCMTs is feasible.Additional treatment was found to improve exercise tolerance and decrease dyspnea in COPD patients.Exercise therapy based on traditional Chinese methods is easy and safe.

AIM: To explore the clinical effects of high frequency electrical capsulotomy in maturation period cataract surgery.
●METHODS: A total of 68 cases of maturation period cataract were selected and underwent the surgery of continuous circular capsulorhexis using the high frequency electrical capsulotomy.
●RESULTS: The success rate was 91% in 68 cases with the high frequency electrical capsulotomy.
● CONCLUSION: The high frequency electrical capsulotomy in maturation period cataract surgery has significant advantages and brilliant clinical values.

Objective: To compile and evaluate the Chinese version of perioperative nursing quality assessment scale, detect and verify the reliability and validity of evaluation scale, and establish a scientiifc evaluation system. Methods: We applied Tuija Leinonene and Helena Leino-kilpi scales as the theoretical framework, and established perioperative nursing quality assessment scale by translation, language study, and expert consultation. hTe questionnaire survey population was 276 patients who had surgery and 200 nurses working in the operating rooms at the 3 Affliated Hospitals of Central South University. hTe scale was tested validity and reliability. Results: Perioperative nurse quality evaluation scale consisted of 32 items and 7 dimensions, including body care, receive information, support, respect, medical staff characteristics, environment and nursing process. The test-retest reliability of scale was 0.977 for patients and 0.997 for nurses. hTe split half reliability of scale was 0.761 for patients and 0.887 for nurses. hTe Cronbach's α of total scale for the patients was 0.918, and the Cronbach's α of factors was 0.658-0.838. hTe Cronbach's α of total scale for the nurses was 0.932, and the Cronbach's α of factors was 0.650-0.836. hTe correlation coeffcient of scale for the patients was 0.363-0.603; the factors and the total correlation coeffcient was 0.535-0.788. hTe correlation coeffcient of scale for the nurses was 0.410-0.700; the factors and the total correlation coeffcient was 0.743-0.902. Conclusion: The Chinese version of the perioperative nursing quality assessment scale is a measurement instrument with a high level of validity and reliability for Chinese society and can be used to determine the quality of perioperative nursing care in our country.

Objective To investigate the efficacy and safety of using stereotactic radiotherapy (SRT) technique for conducting re-therapy after thoracic tumor radiotherapy.Methods Thirty-eight patientswith SRT after receiving thoracic conventional radiotherapy (RT) in our hospital from July 2012 to November 2014 were selected.The treatment target area included the lung local primary lesion,recurrent lesions and lung metastasis tumor.Results Median dose of previous RT was 48 Gy (30-56 Gy).Median biologically equivalent effective dose (alpha/beta=10.0,BED10) of receiving SRT was 62 Gy (39-72 Gy).Median follow up time was 12.30 months;1-,2-year local progression-free survival (LPFS) was 76.32％ and 63.16 ％ respectively.Median recurrence-free (RFS) and overall survival (OS) were 13.20 months and 21.00 months respectively.Grade 2 and 3 pulmonary toxicity was 15.79 ％ and 7.89 ％ respectively.Other grade 2-4 toxicities adverse reactions included chest pain (15.79 ％),fatigue (18.42 ％) and skin lesion(2.63％).No grade 5 toxic injury occurred.Conclusion SRT can be safely and effectively used in the patients previously receiving thoracic RT.
