Objective:To investigate the expression of wild type estrogen receptor(wER)and the ex-on-5 deleted ER(variant ER,vER)in human hepatocellular carcinoma(HCC)samples,and thereafteranalyze the possibility of HCC treatment by endocrine therapy.Methods:The mRNA expressions of wERand vER were analysed from 28 cases of HCC by RT-PCR.The expression of ER at the protein level wasdetected by immunohistochemistry(IHC).Results:IHC results showed that 39.3% of the HCC speci-mens expressed ER.The mRNA of wER was detected in 89.3%(25/28)of the HCC specimens whilethat of vER was detected in 96.4%(27/28).Twenty four out of 28 HCC cases(85.7%)expressedboth wER and vER.One out of 28 patients(3.5%)expressed only wER whereas 3 patients out of 28(10.7%)expressed vER only.Conclusion:Ninety six percent(27/28)of the HCC patients expressedvER,which suggests that the expression of vER is an important event in the development of HCC.

Objective To investigate the expression of macrophage migration inhibitory factor(MIF) in renal tissue of children with Henoch-Schonlein purpura nephritis(HSPN),and its correlation with clinical indexes and pathological changes,and to explore its effect on the pathogenesis of HSPN.Methods According to the clinical manifestation,60 children with HPSN were divided into only purpura group,mixed group and HSPN group.MIF concentration of Henoch-Schonlein purpura(HSP) groups and healthy control group were detected with enzyme linked immunosorbent assay(ELISA).MIF protein expression and the marker of human macrophage(CD68) in renal tissues of HSPN and normal control group were detected with immunohistochemistry method.The total urine protein for 24 hours and urinary N-acetyl-beta-D-glucosaminidase (NAG) level were detected with laboratory routine method.Results MIF concentration in mixed group and HSPN group were significantly higher than that in only purpura group and healthy control group(Pa

OBJECTIVETo explore the molecular mechanism of pain associated with chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS) in the rat model of prostatic inflammation.

METHODSThirty-six male SD rats were equally randomized to an experimental and a control group, the former injected with 50 μl of 3% λ-carrageenan into the ventral prostate to make the model of non-bacterial prostatic inflammation, while the latter with the same volume of sterile saline solution. At 1, 2 and 4 weeks after modeling, the prostate, L6-S1 dorsal root ganglion (DRG) and spinal cord were harvested for examination of the expressions of the nerve growth factor (NGF), transient receptor potential ankyrin 1 (TRPA1), and calcitonin-gene-related peptide (CGRP) by immunohistochemistry and Western blot.

RESULTSThe expressions of NGF, TRPA1 and CGRP in the prostatic tissue were all significantly increased in the experimental group as compared with the control (P <0.05), with a gradual decrease with the prolonging of time (P <0.05). In the L6-S1 DRG and spinal cord, the expressions of NGF, TRPA1 and CGRP exhibited no significant differences between the experimental and control groups at 1 week after modeling (P >0.05) and kept at high levels in the experimental group at 2 and 4 weeks, though not significantly different from those at 1 week (P >0.05). Statistically significant differences were observed in the expressions of the three proteins in the experimental rats among different time points (P <0.05), but not between the two groups at any time point (P >0.05).

CONCLUSIONThe molecular mechanism of CP/CPPS can be evaluated in the rat model of prostatic inflammation established by injecting λ-carrageenan into the prostate. TRPA1 may play an important role in connecting the upstream and down-stream pathways of CP/CPPS-associated pain.

Objective To study the efficacy and safety of T-614 in treating rheumatoid arthritis(RA). Methods Two hundred and eighty patients with active RA were randomly allocated to 3 groups:T-614 50 mg each day,25 mg each day or placebo.Clinical and laboratory parameters were analyzed at baseline,2,4,6,12, 18 and 24 weeks.Results The ACR response rate was significantly higher in the T-614 treatment group com- pared with the placebo group during the first 6 weeks.After 24 weeks,25 mg/d,50 mg/d dosage group and the placebo group showed 39.1%,61.3% and 24.2% in ACR20,23.9%,31.2% and 7.4% in ACR50 respectively.A time-response in ACR response after 24 weeks was observed,with clear superiority of the 25 mg/d and 50 mg/d dosage groups compared to the placebo,and 50 mg/d dosage group compared to 25 mg/d dosage group(P

OBJECTIVE: To investigate the effect of hyperoxia on intestinal metabolomics in mice. METHODS: Sixteen 8-week-old male C57BL/6 mice were randomly divided into hyperoxia group and control group, with 8 mice in each group. The hyperoxia group was exposed to 80% oxygen for 14 days. Mice were anesthetized and euthanized, and cecal contents were collected for untargeted metabolomics analysis by liquid chromatography-mass spectrometry (LC-MS) combined detection. Orthogonal partial least square discriminant analysis (OPLS-DA), volcano plot analysis, heat map analysis, and Kyoto Encyclopedia of Genes and Genomes (KEGG) were used to analyze the effects of hyperoxia on metabolism. RESULTS: (1) OPLS-DA analysis showed that R²Y was 0.967 and Q² was 0.796, indicating that the model was reliable. (2) Volcano plot and heat map analysis showed significant statistical differences in the expression levels of metabolites between the two groups, with 541 up-regulated metabolites, 64 down-regulated metabolites, and 907 no differences, while the elevated 5-hydroxy-L-lysine was the most significant differential metabolite induced by high oxygen. (3) KEGG pathway enrichment analysis showed that porphyrin and chlorophyll metabolism (P = 0.005), lysine degradation (P = 0.047), and aromatic compound degradation (P = 0.024) were the targets affected by hyperoxia. (4) Differential analysis of metabolic products through KEGG enrichment pathway showed that hyperoxia had a significant impact on the metabolism of porphyrin and chlorophyll, lysine, and aromatic compounds such as benzene and o-cresol. CONCLUSIONS Hyperoxia significantly induces intestinal metabolic disorders. Hyperoxia enhances the metabolism of porphyrins and chlorophyll, inhibits the degradation of lysine, and delays the degradation of aromatic compounds such as benzene and o-cresol.

OBJECTIVETo investigate the effect of Bushengzhuyang Fang (Yangjing Capsule, YJC) on penile erectile function and its action mechanisms in rats.

METHODSFifty-six male SD rats were randomly divided into seven groups of equal number: blank control, daidzein, daidzein + testosterone, daidzein + sildenafil, daidzein + low-dose YJC, daidzein + medium-dose YJC, and daidzein + high-dose YJC. The rats in the blank control group were treated intragastrically with normal saline and those in the other groups with daidzein at the dose of 100 mg per kg per day for 30 days. Then the last five groups received additionally testosterone (4 mg per kg per day), sildenafil (2.5 mg per kg per day), low-dose YJC, (0.315 mg per kg per day), medium-dose YJC (0.63 mg per kg per day), and high-dose YJC (1. 26 mg per kg per day), respectively. At 0, 30 and 60 days of treatment, we observed the apomorphine-induced spontaneous erectile response and pathological changes in the corpus cavernosum of the rats, recorded the number of penile erection and erectile incubation period, and determined the serum levels of testosterone (T) and luteinizing hormone (LH).

RESULTSAt 30 days of treatment, the number of apomorphine-induced erections was decreased, the erectile incubation period prolonged, and the serum levels of T and LH reduced remarkably in all groups of rats (P < 0.05). Compared with the findings at 30 days, the number of penile erections was significantly decreased at 60 days in the daidzein group (1.39 ± 0.42 vs 2.67 ± 0.33, P < 0.05) and daidzein + low-dose YJC group (1.33 ± 0.49 vs 2.83 ± 0.61, P < 0.05); the erectile incubation period was markedly ex- tended ([16.33 ± 3.11] vs [8.50 ± 0.93] min and [15.50 ± 3.21] vs [8.63 ± 1.54] min, P < 0.05); and the serum levels of T ([5.34 ± 0.89] vs [1.24 ± 0.30] ng/ml and [5.28 ± 1.12] vs [2.07 ± 0.76] ng/ml, P < 0.05) and LH ([3.62 ± 0.37] vs [2.09 ± 0.12] ng/ml and [3.79 ± 0.28] vs [2.17 ± 0.33] ng/ml, P < 0.05) were significantly reduced in the daidzein and daidzein + low-dose YJC groups, respectively. Pathological examination revealed slightly decreased cavernous sinuses and blood vessels in the corpus cavernosum of the rats in the daidzein + testosterone, daidzein + sildenafil, daidzein + medium-dose YJC, and daidzein + high-dose YJC groups as compared with those in the blank control group.

CONCLUSIONHigh-dose Yangjing Capsule is efficacious for the recovery of erectile function in rats, especially for phytoestrogen-induced erectile dysfunction.

OBJECTIVETo explore the efficacy of compound ciprofloxacin suppository (CCS) combined with Ningbitai (NBT) and Yunnan Baiyao (YB) capsules in the treatment of histological prostatitis with elevated levels of PSA.

METHODSThis study included 150 cases of type IIIA histological prostatitis, with PSA levels ranging from 4 to 50 microg/L. After 1 month's treatment with oral Levofloxacin tablets at 0.5 g qd, the PSA levels remained high in 86 patients. Prostate cancer was excluded by transrectal ultrasound-guided prostatic biopsy, and histological prostatitis was confirmed in 65 patients, who were assigned to an experimental group (n=45) and a control group (n=20) to receive CCS combined with NBT and YB capsules and CCS with NBT only, respectively, both for 4 weeks. We determined the PSA levels, obtained NIH-CPSI scores before and after medication, and compared them between the two groups.

RESULTSThe two groups were well balanced in demographics and baseline characteristics. After treatment, both showed significant differences in the PSA level, PSA density (PSAD) and CPSI scores from the baseline (P<0.05), and there were also statistically significant differences between the two groups in the changes of the PSA level and CPSI scores after medication (P = 0.029 and 0.001).

CONCLUSIONCompound ciprofloxacin suppository combined with Ningbitai and Yunnan Baiyao capsules can significantly decrease the level of serum PSA and relieve related symptoms in III A histological prostatitis with PSA elevation, and Yunnan Baiyao capsules can significantly enhance the therapeutic effect.
