1.A research on the structure and biological functions of PPAR? and its relationship with diseases
Chinese Pharmacological Bulletin 2003;0(09):-
PPAR ? is one of the three isoforms of peroxisome proliferator-activated receptors (PPARs) which are essential regulators of lipid storage and metabolism. PPAR ? primarily stimulats lipid metabolism and energy uncoupling in adipocytes and myocytes as well as involvs in the onset and development of many diseases. As the target of medicines, PPAR ? agonists may be powerful drugs for epidermal wound and metabolic syndrome X.

International Eye Science 2017;17(6):1153-1154
AIM: To observe the interocular symmetry of primary angle-closure suspects` (PACS) parameters using IOL Master.METHODS: A cross-sectional observational study.Totally 112 eyes from 56 subjects were enrolled to detect the difference of the bilateral axial length (AL), anterior chamber depth (ACD) and white to white distance(WTW), and to evaluate the correlation between the interocular differences of △AL, △ACD and △WTW and age, gender.RESULTS: All the parameters were analyzed by paired-samples t test and there were no significant interocular difference (P>0.05).There was no relation of ΔAL,ΔACD and ΔWTW with age and gender.CONCLUSION: Interocular symmetry of parameters by IOL Master was observed in PACS, and we found that the symmetry would not be altered when the age and gender had changed.

5.Grading, staging and prognosis of follicular lymphoma: the value of 18F-FDG PET/CT
Chinese Journal of Nuclear Medicine and Molecular Imaging 2014;34(1):23-26
Objective To evaluate the value of 18F-FDG PET/CT in histological grading and staging of follicular lymphoma (FL) and prediction of prognosis after first-line treatment.Methods From May 2007 to April 2013,24 patients (11 males,13 females; median age 55 years) with histopathological proof of FL were retrospectively studied.All patients were evaluated by 18F-FDG PET/CT before the first-line treatment and were divided into indolent FL and aggressive FL according to their histological grades and clinical stages.The sensitivity,specificity and SUVmax were calculated.Analysis of variance of factorial design was used to analyze the data.Within the same study period,18F-FDG PET/CT was also performed in 16 FL patients (9 males,7 females; median age 50.5 years) after first-line treatment (7/16 patients belonged to the aforementioned group with pretreatment PET/CT performed) ; and they were then divided into PET/CTpositive and PET/CT-negative groups.All 16 patients were followed for 6-49 months to evaluate the prognosis.The rates of overall survival (OS) and progression-free survival (PFS) were calculated.Results (1)The sensitivities of PET/CT in indolent and aggressive FL were 92.3% (12/13) and 100% (11/11),respectively.The SUVmax was 5.26± 1.70 vs 9.54±5.09 (F=5.196,P<0.05).(2) According to PET/CT,3patients(12.5%,3/24) were upstaged from Ⅰ-Ⅱ to Ⅲ-Ⅳ,and 2 patients(8.3%,2/24) were downstaged from Ⅲ-Ⅳ to Ⅰ-Ⅱ.The SUVmax of stage Ⅰ-Ⅱ and Ⅲ-Ⅳ FL was 5.22±2.92 and 8.04±4.46(F=2.904,P>0.05).(3)For the 16 FL patients with PET/CT after first-line treatment,the negative and positive groups had different OS and PFS.The 6-month OS,1-year OS and 3-year OS were 100%(13/13),9/9,4/5,respectively for the negative group,and 2/3,2/3,1/2,respectively for the positive group; while the corresponding 6-month PFS,1-year PFS and 3-year PFS were 92.3 % (12/13),8/9,3/5 and 2/3,0/3,0/2,respectively.Conclusions 18F-FDG PET/CT is valuable in the evaluation of histological grading and clinical staging of FL patients and in the prediction of prognosis after fist-line treatment.

Calcineurin inhibitors,such as cyclosporin A and tacroli mus,are widely-used i mmuno-suppressive drugs clinically.However,renal toxicity,hyperglycae mia and other side-effects can occur over long-term use.Isolation of novel calcineurin inhibitors fro m medicinal plants in recent years has pro-vided a new approach to the development of new immunosuppressive drugs with high efficiency and low toxicity.Recnt studies have shown that medicinal plant extracts, such as isogarcinol, quercetin, kae mpferol,phenylethanoid glycosides,ere mophilane sesquiterpenes A and B,pisiferdiol,as well as extracts fro m Smilax china L and Jasminum humile L,have obvious inhibitory effect on calcineurin.

Objective To observe the effects of intensive insulin therapy on C-reactive protein (CRP) ,interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α ) in the patients of critical illness complicated with hyperglycemia and its incidence of side effect. Methods Two hundred and nine patients of critical illness complicated with hyperglycemia were randomly divided into intensive insulin therapy group (106 patients,blood glucose maintained at a level of 4.4-6.1 mmol/L) and conventional insulin therapy group ( 103 patients, blood glucose maintained at a level of 9.0-11.1 mmol/L). Serum levels of CRP,TNF- α and IL-6 were determined on 0,24,48,72 h respectively after ICU admission. Results The levels of blood glucose of both groups reached the target level. The incidence rates of the hypoglycemia had no significant difference between two groups [6.60 % (7/106) vs. 4.76% ( 3/63 ),P > 0.05]. After 72 h treatment, serum level of CRP in intensive insulin therapy group was significantly lower than that in conventional insulin therapy group (P < 0.05 ). After 24,48 and 72 h treatment, serum level of IL-6 in intensive insulin therapy group was significantly lower than that in conventional insulin therapy group (P < 0.05 ). After 48 and 72 h treatment, serum level of TNF-αin intensive insulin therapy group was significantly lower than that in conventional insulin therapy group (P < 0.05). Conclusion Intensive insulin therapy can significantly decrease the levels of non-specific inflammatory factors in patients of critical illness complicated with hyperglycemia, which brings beneficial effect to the patients.
8.The Effect of Different Frequency and Time of Transcutaneous Electrical Nerve Stimulation to Current Perception Threshold
Tianjin Medical Journal 2014;(6):578-580
Objective To analysis the consequence of current perception threshold (CPT) by different frequency and time of transcutaneous electrical nerve stimulation (TENS). Methods CPT of foramen area and arm area was measured to evaluate the effect of TENS. Different frequency and time of TENS was given to 30 healthy volunteers. Stimulating to Hegu, CPT of the foramen area and the arm area on the same side was measured. Results CPT of the foramen area increased with stimulation. Low frequency of TENS inhibited the chronic pain significantly(P<0.05),high frequency of TENS inhibited both of the chronic pain and the acute pain(P<0.05). The inhibition of pain is more influenced by the frequency of TENS than the time of it. Conclusion Channel and point of TENS can influence CPT of the specific reaction area. And the choice of appropriate frequency of the treatment is more important than extending the treatment time alone.

Objective To study the DNA damage and repair of normal lung interstitial cells and human lung adenocarcinoma cells exposed to cigarette smoke. Methods Cultured human embryo lung fibroblasts (HLF) and human lung adenocarcinoma A549 cells. Mainstream smoke was collected by using dimerhyl sulfoxide (DMSO) and phosphate buffer solution (PBS) as absorbents. MTT assay was used to test the cytotoxicity of the solutions of cigarette smoke, then selected the concentrations of the solutions with no obvious cytotoxicity to treat cells and detected DNA damage and repair by comet assay. Results As treated with original solutions or 1/2 dilution of DMSO cigarette smoke solutions only, the Viability of cells was below 80%, but it was beyond 80% when treated with PBS solutions. The results showed that a significant difference of DNA damage was seen between the treated groups and negative control groups (P0.05),but the DNA damage caused by DMSO solutions was worse than PBS solutions significantly (P
