OBJECTIVETo compare the efficacy differences between fire needling therapy and oxycycline tablets for the treatment of moderate to severe acne vulgaris.

METHODSSixty cases of moderate to severe acne vulgaris were randomly divided into a fire needling group and a medication group, 30 cases in each one. The pricking method of fire needling at Ashi points around damaged skin was applied in the fire needling group, once every five days for totally 4 times. The oral administration of oxycycline tablets, 100 mg, was applied in the medication group, twice daily for 20 days, also external application of adapalene gel before sleep was adopted. The fading time of skin damage, including papule, pustule, nodule and cyst in the two groups was recorded and clinical efficacy was compared. After the treatment, two-month follow-up was performed to observe the recurrence rate in the two groups.

RESULTSThe curative rate was 69.0% (20/29) in the fire needling group, which was statistically different from 40.0% (12/30) in the medication group (P < 0.05). The fading time of each type of skin damage in the fire needling group was shorter than that in the medication group [papule: (2.67 +/- 0.66) d vs (4.36 +/- 0.61) d; pustule: (2.47 +/- 0.57) d vs (4.27 +/- 0.55) d; nodule: (7.76 +/- 1.06) d vs (9.88-1.30) d; cyst: (11.81 +/- 1.54) d vs (14.79 +/- 0.89) d, all P < 0.05]. The recurrence rate was 46.4% (13/28) in the fire needling group, which was not significantly different from 44.0% (11/24) in the medication group (P > 0.05).

CONCLUSIONThe acne vulgaris could be fast and effectively treated by fire needling therapy, which has shorter fading time than oxycycline tablets. However, the preventive effect is not different between the two theraies.

To establish an HPLC-MS/MS method for the analysis of quercetin, kaempferid and isorhamnetin in rats plasma and study its pharmamacokinetics after an intragastrical administration of Hippophae rhamnoides extracts. Five healthy male Sprague-Dawley (SD) rats were given single doses of H. rhamnoides extracts (quercetin 26.35 mg x kg(-1), kaempferid 4.040 mg x kg(-1), isorhamnetin 31.37 mg x kg(-1)), and then their orbital sinus blood samples were collected at different time points. The drug plasma concentration of the three flavonoids was determined by HPLC-MS/MS method. After that, the main pharmacokinetics parameters were calculated by using Kinetica 5. 0. 11 software. The methodological test showed that the linear concentration ranges of quercetin, kaempferid and isorhamnetin were 7.500-600.0 μg x L(-1) (R2 = 0.998 5), 1.000-80.00 μg x L(-1) (R2 = 0.998 5 ) and 10.00-800.0 μg x L(-1) (R2 = 0.998 0), respectively. The inner and inter-days precisions were both less than 14.0%. The plasma samples showed a good stability and consistency with the requirement of biological sample analysis after the samples were frozen once and placed at - 20 degrees C for 15 d and room temperature for 6 h and the treated analytes were placed at -20 degrees C for 24 h. For quercetin, the pharmacokinetic parameter t(½β), AUC(0-∞), MRT(0.∞), C.(max) and T(max) were (113.3 ± 19.37) min, (12 542.14 ± 3 504.05) μg x h x L(-1), (119.6 ± 13.29) h, (164.6 ± 27.33) μg x L(-1) and (5.199 ± 0.840 3) h, respectively. For kaempferid, the pharmacokinetic parameters t(½β), AUC(0-t), MRT(0-∞), C(max) and T(max) were (79.85 ± 17.15) min, (934.51 ± 94.59) μg x h x L(-1), (81.50 ± 13.75) h, (80.15 ± 14.24) μg x L(-1) and (3.827 ± 0.902 7) h, respectively. For isorhamnetin, the pharmacokinetic parameters t1,2,, AUC(0-t), MRT(0-∞), C(max) and T(max) were (118.3 ± 20.73) min, (26 067.77 ± 4 124.60) μg x h x L(-1), (129.0 ± 16.30) h, (269.6 ± 29.32) μg x L(-1) and (6.513 ± 1.450) h, respectively. The HPLC-MS/MS analysis method established in this study was proved to be sensitive and accurate and could be applied in the pharmacokinetic study of quercetin, kaempferid and isorhamnetin in rat plasma.

This study aims to assess if adverse drug reactions (ADRs) to Kudiezi injection are allergic in origin. Hospital information system (HIS) data from 18 hospitals in China were used to carry out a nested case control design study. Included were patients who received dexamethasone for suspected allergic reactions after receiving Kudiezi injection. These were compared with non-allergic reaction people. Single factor logistic regression and multiple factor logistic regression were used to analyze data. Condition on admission, allergic history, dosage, disease status and drug combinations were taken into account in cases of suspected allergic reactions. After analysis in two subgroups we found that the condition on solvents had a significant effect, P values were 0.005 5 and < 0.000 1 on suspected cases of allergic reactions. For the first subgroup analysis, we found using other eight injections at the same time as Kudiezi injection could be risk factors in suspected cases of allergic reactions. For the second subgroup analysis combining using mannitol or fructose could increase risks. Based on this current research, condition on admission as well as the concomitant use of some other drugs may be the risk factors in suspected cases of allergic reactions. However, further research for verification is required. This study can provide guidance for safe clinical practice in using Kudiezi injection.

To explore the effect of Kudiezi injection on renal function in the real world, in order to provide the basis for the clinical medication safety. Patient aged between 18-80 were selected from 18 large hospitals information system (HIS) databases established by clinical research institute for basic traditional Chinese medicine of China academy of Chinese medical sciences. The patients who were treated with Kudiezi injection (24 225 cases) were defined as the exposed group, whereas those who were not treated with Kudiezi injection (14,191 cases) were defined as the non-exposed group. The propensity score method was used to balance the confounding factors. Classic logistic regression, GBM weighted propensity score logistic regression, GBM propensity score weighted logistic regression with covariate and sensitivity analysis were adopted to study the effect of Kudiezi injection on renal function. The results showed no significant difference in the possibility in abnormality in serum creatinine (Scr) (P = 0.940, 0.679, 0.834) and urea nitrogen (BUN) (P = 0, 0.045, 0.164) between both groups. Therefore, the existing data indicated no damage of Kudiezi injection on renal function. Because this study is a retrospective study based on the real world, there may be unknown confounding factors and potential bias. Therefore, further studies shall be conducted to monitor whether Kudiezi injection causes damage on renal function, in order to ensure the clinical medication safety.

OBJECTIVETo study the relationship between TMPRSS2: ERG gene fusion and the pathological grade of prostate cancer (PCa).

METHODSWe collected fresh prostatic tissue samples from 62 patients with PCa and another 10 with benign prostatic hyperplasia ( BPH) and included 9 cancer cell strains as the control. We examined the TMPRSS2:ERG fusion gene in the PCa samples by nest RT-PCR, compared the Gleason scores between the TMPRSS2:ERG-positive and -negative cases, and analyzed the association of TMPRSS2: ERG fusion with the pathological features of PCa.

RESULTSThe TMPRSS2: ERG fusion gene was detected in 28 (45.16%) of the PCa cases, but in none of the 10 BPH cases or the 9 cancer cell strains. No statistically significant differences were found in the Gleason scores between the TMPRSS2:ERG-positive and -negative cases (Z = -0.609, P = 0.542), but the primary Gleason score was markedly higher in the former than in the latter (Z = -2.600, P = 0.009). Univariate logistic regression analysis showed that TMPRSS2:ERG was associated with the cribriform growth pattern (OR = 6.250, P = 0.002), foamy gland morphology (OR = 6.666, P = 0.023), and signet-ring cells (OR = 3.240, P = 0.035), but multivariate logistic regression analysis manifested that it was associated with the cribriform growth pattern only (OR = 3.750, P = 0.033).

CONCLUSIONTMPRSS2:ERG gene fusion was associated with higher pathological grades of prostate cancer.

Objective To develop a multiplex PCR-based reverse line blot(mPCR/RLB) hybridization assay to detect,simultaneously,seven genes encoding AR-erm(A/TR),erm(B),mef(A/ E),tet(M),tet(O),aphA-3,aad-6 and two AR-related genes,int-Tn and mreA in group B streptococcus.Methods Nine pairs of specific primers and Oligonucleotide probes targeting erm(A/TR), erm(B),mef(A/E),tet(M),tet(O),aphA-3,aad-6 int-Tn and mreA respectively were modified according to former studies or designed in this study.The primers and probes were labeled with biotin and amino,respectively.The nine genes were amplified simultaneously in the same tube.PCR product hybridized with the probes labeled in the BiodyneC nylon membrane to detect the nine genes.To detect the sensitivity and specificity of the method developed,PCR with single pair of primer targeting each gene were tested in 318 isolates tested and the results were compared with the one abtained by RLB.Results The nine resistance-related genes could be successfully detected by mPCR/RLB assay developed in this study.Based on sequencing,21 of 22 isolates with mef had mef(E)and eight of 353 with int-Tn had an atypical sequence.Except for the above 29 genes,all the others corresponded well with the results obtained by single pair primer PCR.Conclusion The mPCR/RLB assay developed in this study is simple,rapid and suitable for surveillance of antibiotic resistance in GBS.

Adult male Kunming mice were divided into normal control group,propylthiouracil(PTU) treated group and PTU+T_4 treated group.Neurogranin(Ng)protein expression in the hippocampus after 8 weeks was assayed by Western blotting and immunohistochemical method.Results showed that Ng protein was decreased in the hippocampus of male mice with adult-onset hypothyroidism,suggesting that decreased Ng,which is correctable by T_4,is involved in cognitive dysfunction in adult-onset hypothyroid male mice.

Dendritic cells (DCs)are the most potent antigen presenting cells,which play crucial roles in initiating and amplifying both the innate and adaptive immune responses.In DCs' whole life,the dynamics of cytoskeleton is involved in the regulation of their deformation,migration,adhesion,endocytosis and antigen presentation.The cytoskeleton is a complex system and regulated by lots of cytoskeletal proteins.With the research going,our understanding on cytoskeleton system is getting clear.Based on these,we summarized the effects of filamentous actin (F-actin)cytoskeleton remodeling on the morphology and immune functions of DCs.
