Objective To observe the relationship between serum lipid concentration profiles and thyroid function after thyroid hormone withdrawal( THW) in patients with differentiated thyroid carcinoma( DTC) .Methods Sixty-five post-operative DTC patients who prepared to receive radioiodine ablation were included in this study.Serum thyroid hormones ( TSH, FT4 , FT3 ) and lipid profile [ total cholesterol ( TC ) , triglycerides ( TG ) , low-density lipoprotein-cholesterol(LDL-C), and high-density lipoprotein-cholesterol(HDL-C)] levels were measured before and 3 weeks after THW.The relationship between serum lipid profile concentrations and thyroid hormone levels were measured.Results Before surgery, HDL-C level showed a significant positive correlation with TSH level(r=0.273, P=0.041), whereas other lipid profile did not show any significant correlation with thyroid hormones levels.Before THW, no correlation was observed between thyroid hormones and lipid profile.After 3 weeks′THW, the TC level was correlated with FT4 and FT3 levels(r were-0.321 and-0.415, respectively, both P<0.01).The LDL-C level was correlated with FT4 level(r=-0.347, P=0.005).The HDL-C level was significantly correlated with TSH, FT3, and FT4 levels (r were 0.342,-0.452, and-0.478, all P<0.01).The serum LDL-C level in patients with TSH above 50 mU/L(n=50) was higher than that in patients with TSH below 50 mU/L(n=15, P=0.001), while serum TC, TG and HDL-C levels were not significantly different between those two groups(P>0.05).Conclusion The serum lipid profile varies with the change of serum thyroid hormones after THW in postoperative DTC patients.

OBJECTIVESTo investigate the cause of chronic pelvic pain syndrome (CPPS) and the correlation between presence of bacterial signal and the response to antibiotics by detecting bacterial 16S rRNA gene signal using polymerase chain reaction (PCR).

METHODSEPS and first void urine (VB1) from 59 men with CPPS were analyzed by PCR for bacterial signal using universal primers specific for bacterial 16S rRNA gene. If the bacterial signal was found only in EPS or the EPS bacterial signal was at least 10 times stronger than the VB1 one, positive result could be decided for bacterial signal detection. All patients were treated with levofloxacin and azithromycin for 4 weeks. The treatment could be considered effective if more than 50% improvement, compared to the state before the treatment, was achieved in the symptom severity index(SSI), symptom frequency questionnaire(SFQ), national institutes of health chronic prostatis symptom index of pain(quasi-CPSI) or the patients' general subjective assessment.

RESULTSPositive bacterial signal was detected in 46 of the 59 CPPS patients; The difference of improvement rates between positive bacterial signal group and negative bacterial signal group, which were 65%-74% and 0 respectively, was significant.

CONCLUSIONSThe basis of detecting 16S rRNA gene signal by PCR in clinical practice was built. The study shows that bacterial infection is related to CPPS. Bacterial signal detection results can help predict the effect of antimicrobial therapy.

OBJECTIVE: To determine the cellular compatibility of combined deproteinized bone(DPB) coated with hepatocyte growth factor (HGF), and to observe the adherent effect of osteoblasts in response to HGF. METHODS: Osteoblasts were isolated from fetal rabbits. Osteoblasts were cultured with DPB coated with HGF and deproteinized bone as experimental group and contral group, respectively. The proliferation and alkalinephosphatase activity were tested. Their growth was examined by inverted phase contrast microscope and scanning electronmicroscope. RESULTS: The osteoblasts were attached to the outside and inside surfaces and grew well. HGF/DPB could stimulate the alkalinephosphatase activity of the osteoblasts and improve the proliferation of the osteoblasts. CONCLUSION HGF/DPB has good biocompatibility and bone induction. HGF could improve the adherent effect of DPB on osteoblasts, and it could be used as scaffold material for the bone tissue engineering.

OBJECTIVETo observe therapeutic effect of electroacupuncture (EA) at Jiaji (EX-B 2) combined with laser needle-knife on lumbar disc herniation.

METHODSOne hundred and twenty cases of lumbar disc herniation were divided into an Jiaji EA group, a laser needle-knife group and a combination group (Jiaji EA plus laser needle-knife) according to random number table. Changes of symptoms at different stages before and after treatment were investigated with SF-MPQ cumulative scores.

RESULTSAll the 115 cases completed all of the study, SF-MPQ score in the combination group was significantly lower than those in the Jiaji EA group and the laser needle-knife group (P<0. 01, P<0.05), with a significant difference at the end of treatment of 2 weeks (P<0.01) between the laser needle-knife group and the Jiaji EA group, and with no significant difference at treatment of 1 week and 3 weeks (P>0.05). The recurrence rate at a half year later in the combination group was significantly lower than those in laser needle-knife group and the Jiaji EA group (P<0.05).

CONCLUSIONEA at Jiaji (EX-B 2) combined with laser needle-knife can significantly increase clinical therapeutic effect, alleviate pain of the patient and reduce recurrence.

Objective: To explore the effect of 6 common cytogenetic abnormalities on the prognosis of multiple myeloma (MM). Methods: Myeloma cells from a cohort of 532 newly-diagnosed MM patients enrolled were enriched by CD138 immunomagnetic beads, then detected 13q-, 17p-, 1q+, t (4;14), t (11;14) and t (14;16) and other common genetic abnormalities in MM by using interphase fluorescence in situ hybridization (FISH) technique to compare the influence of different genetic abnormalities on their prognoses. Results: The rate of cytogenetic abnormalities was 78.20% (416/532) in 532 patients, of which 13q-accounted for 42.29% (225/532), 17p-16.35% (87/532), 1q+ 53.38% (284/532), t (4;14) 25.94% (138/532), t (11;14) 21.62% (115/532), t (14;16) 2.07% (11/532). Six kinds of cytogenetic abnormalities were analyzed, 13q- and 17p-, 1q+, t (4; 14), t (14;16) were all correlated (P <0.05). The univariate analysis indicated that 13q-, 1q+, t (4;14) and t (14;16) had a significant effect on progression-free survival (PFS), 13q-, 17p-, t (4;14) and t (14;16) had a marked influence on overall survival (OS). The multivariate analysis showed that 1q+, t (4;14) and t (14;16) were independent adverse factors of PFS, 17p-, t (4;14) and t (14;16) were independent unfavorable factors of OS. According to the independent prognosis factors number-based groups, the median PFS with 0, 1, 2, 3 independent prognosis factors of patients were 30.9, 28.4, 18.7 and 17.6 months (P =0.035) respectively, and the median OS were 54.4, 46.1, 38.0 and 21.2 months (P =0.004) respectively. Conclusion 1q+, 17p-, t (4;14) and t (14;16) were independent prognostic factors affecting the survival of MM patients. 13q-is often accompanied by 17p-, 1q + and (or) t (4;14) , simply 13q- was not an independent prognostic factor; the more number of independent prognostic factors, the worse the prognosis of patients.

Objective: To study the effects of hedysarum polybotys saccharides (HPS) and selenizated hedysarum polybotys saccharides (SE-HPS) on the oral squamous cancer cell line SCC25. Methods: Different concentrations (0, 10, 25, 50, 100, 200, 400 μg/ml) of HPS and SE-HPS were added to SCC25 cells in the logarithmic growth stage. Cell proliferation was detected by the CCK-8 method, apoptosis was detected by flow cytometry, and apoptosis-related indexes were observed by RT-qPCR and Western blotting. Results : The concentrations of HPS and SE-HPS inhibited the proliferation of SCC25 cells. The inhibitory effect of 50 μg/mL HPS and SE-HPS on the proliferation of SCC25 cells was the strongest and was time-dependent. The inhibition effect significantly increased within 48 h, and the effect was achieved after 48 h. At the plateau stage, SE-HPS inhibited the proliferation of SCC25 cells more strongly than HPS (P < 0.05). The results of flow cytometry showed that 50 μg/mL HPS and SE-HPS acted on SCC25 cells for 48 h, and the apoptotic rates were 25.8% and 30.8% respectively. Compared with the control group (0 μg/mL HPS and SE-HPS), the difference was statistically significant (P < 0.05). RT-qPCR and Western blotting showed that 50 μg/mL HPS and SE-HPS acted on SCC25 cells for 48 h, and the mRNA and protein expression levels of the apoptosis gene Fas/FasL were upregulated. The difference was statistically significant (P < 0.05). Conclusion Both HPS and SE-HPS can inhibit the proliferation of SCC25 oral cancer cells, but SE-HPS is superior to HPS and can induce apoptosis through the Fas/Fasl pathway.

Objective: To analyze the significance of serum free light chain (sFLC) for the prognosis of the patients with newly diagnosed multiple myeloma (NDMM). Methods: The clinical data of 621 NDMM patients in Changzheng Hospital from June 2010 to December 2016 was retrospectively analyzed. The serum free light chain levels were measured and the ratios of κ/λ chains were calculated. The significance of serum free light chain ratio (sFLCR) for the prognosis of NDMM patients was analyzed. Results: Among the 621 NDMM patients, 42 patients (6.8%) were in the normal free light chain ratio group (0.26≤sFLCR≤1.65), 247 patients (39.8%) were in the low free light chain ratio group (0.01＜sFLCR＜0.26 or 1.65＜sFLCR＜100), and 332 patients (53.5%) were in the high free light chain ratio group (sFLCR≤0.01 or sFLCR≥100). Compared with normal sFLCR group, the abnormal sFLCR group showed low level of hemoglobin; elevated levels of bone marrow plasma cells, serum creatinine and β 2 -MG, and more patients were in DS stage Ⅲ and ISS stage Ⅲ with high risks of cytogenetics(all P＜0.05). The overall survival (OS) in the normal sFLCR group was significantly better than the abnormol sFLCR groups (not reached vs 58.7 months, P=0.043). Compared with the patients with both high sFLCR and low risks of cytogenetics, the patients with high sFLCR and high risks of cytogenetics showed shorter overall survival time (median OS time was 41.6 months vs 61.4 months, P=0.015). Conclusion The NDMM patients with significantly abnormal sFLCR may indicate more tumor load and higher aggressive progression. sFLCR should be an independent prognostic indicator for the outcome of multiple myeloma. The patients with high sFLCR and cytogenetic abnormalities, have worse prognosis than the others.

Five new saponins, including three steroid saponins, paristenoids A-C (1-3), and two triterpenoid saponins, paristenoids D-E (4-5), along with four known ones (6-9) were isolated from the rhizomes of Paris polyphylla var. stenophylla. The structures of the isolated compounds were identified mainly by detailed spectroscopic analysis, including extensive 1D and 2D NMR, MS, as well as chemical methods. Compound 3 is a new cyclocholestanol-type steroidal saponin with a rare 6/6/6/5/5 fused-rings cholestanol skeleton, and this skeleton has been first found from the genus Paris. The cytotoxicities of the isolated compounds against three human three glioma cell lines (U87MG, U251MG and SHG44) were evaluated, and compound 7 displayed certain inhibitory effect with IC₅₀ values of 15.22 ± 1.73, 18.87 ± 1.81 and 17.64 ± 1.69 μmol·L^-1, respectively.
