A 53-year-old male patient was admitted to the hospital on March 26, 2006. Ten years prior to the presentation, a small furuncle developed on the dorsum of his right hand, and subsided after 2-week treatment with erythromycin ointment; one month later, a broadbean-sized cutaneous ulcer developed on the dorsum of the same hand. After anti-infective treatment, the ulcer healed while the lesional skin thickened, and long-term topical treatment with compound dexamethasone acetate cream showed no obvious effect Dermatological examination revealed an irregular verrucous plaque measuring 2.5 cm × 4 cm with little exudation on the dorsum of the right hand. KOH preparation of the skin lesion revealed brown spores. Sabouraud's dextrose agar culture grew restricted, velvety and dark green colony, and microscopy revealed branched, globular conidiophores generated by cladospores. DNA sequencing showed that the isolate was different from Cladosporium sphaerospermum (AB100654) by 2 bases in the sequence of D1/D2 region of 26S rDNA, from Cladosporium sphaerospermum (AY625063) by 5 bases in the sequence of internal transcribed spacer 1 and 2 (ITS 1 and ITS 2), but fully consistent with Cladosporium sphaerospermum (AM 176719) in the sequence of ITS region. The isolate was identified as Cladosporium sphaerospermum. Hematoxylin-eosin stain of the lesional tissue revealed granulomatous changes,and PAS stain demonstrated brown spores. A diagnosis of phaeohyphomycosis was made. Antifungal susceptibility testing indicated that the isolate was highly sensitive to itraconazole. The lesion obviously subsided after treatment with oral itraconazole 0.2 g once daily for 8 weeks, but the patient was lost to follow up 2 months later.

Background:Tryptophan(TRP)is an essential amino acid,and can produce 5-hydroxytryptamine(5-HT)via 5-HT signal pathway and kynurenine( KYN)metabolic pathway under the catalysis of enzyme,thereby participating in the pathogenesis of visceral hypersensitivity in diarrhea-predominant irritable bowel syndrome(IBS-D). Aims:To investigate the relationship between visceral sensitivity and TRP metabolic pathway in patients with IBS-D. Methods:Thirty patients with IBS-D and 30 healthy controls from June 2012 to January 2014 at Guangdong Provincial TCM Hospital were enrolled. Score of gastrointestinal symptom rating scale( GSRS)was evaluated. Visceral sensitivity was measured by anorectal manometry. RT-PCR and Western blotting were used to detect mRNA and protein expressions of colon mucosal IDo, respectively. Serum 5-HT,5-HIAA,TRP,IDo,KYN,KYNA concentrations and IDo activity,KAT activity were determined by high performance liquid chromatography assay. Results:Compared with control group,GSRS score was significantly increased(P < 0. 05),initial perception threshold,defecation threshold,pain threshold were significantly decreased(P < 0. 05),anorectal constriction pressure was significantly increased( P < 0. 05),serum 5-HT,5-HIAA concentrations were significantly increased(P < 0. 05),mRNA and protein expressions of IDo were significantly increased (P < 0. 05),serum KYN was significantly increased(P < 0. 05),KYNA was significantly decreased(P < 0. 01),IDo activity was significantly incseased(P < 0. 01),and KAT activity was significantly decreased in IBS-D group(P < 0. 01). Correlation analysis showed that initial perception threshold,defecation threshold,pain threshold and anorectal constriction pressure were correlated with 5-HT,5-HIAA,TRP,KYN,KYNA,IDo activity and KAT activity in patients with IBS-D (P < 0. 05). Conclusions:TRP metabolic pathway is correlated with visceral hypersensitivity in patients with IBS-D.

The proportions of subjects with harmonious constitution, qi deficiency, and yang deficiency in the treatment group after the intervention, 6 months and 12 months after the intervention were significantly different from that prior to the intervention (P<0.01). The proportions of subjects with harmonious constitution, qi deficiency, and yang deficiency in the treatment group after the intervention, 6 months and 12 months after the intervention were significantly different from that in the control group (P<0.01).ConclusionFu Liu Zhen plus moxa-box moxibustion at umbilicus can improve the qi-deficiency and yang-deficiency constitutions in the community population.

Objective To investigate the cytokines levels in peripheral blood of ulcerative colitis (UC) patients at active stage, and to observe the effect of baicalin at various concentrations on the cytokines. Methods Quantitative polymerase chain reaction (Q-PCR) assay was used for the detection of interleukin 4 receptor (IL4R), IL6R, IL23R and RAR-related orphan receptor C (RORC) expression in single peripheral mononuclear cell of UC patients. Enzyme-linked immunosorbent assay (ELISA) was used to examine the serum levels of interferon gamma (IFN-γ), IL-4, IL-5, IL-6, IL-10, and transforming growth factor beta (TGF-β) levels in UC patients, and was applied for in-vitro detection of these indicators after baicalin intervention. Results Q-PCR results showed that IL4R, IL6R, IL23R, RORC gene expression levels in UC patients were increased to various degrees as compared to diarrhea-predominant irritable bowel syndrome (IBS-D) patients and the healthy volunteers, and then the levels were decreased to various degrees after intervention by baicalin at different concentrations, in particular at 20 and 40μmol/L. The results of ELISA showed that serum levels of cytokines of IFN-γ, IL-5, IL-6 in UC patients were increased to various degrees while IL-4, IL-10 and TGF-β1 was decreased as compared to IBS-D patients and the healthy volunteers. Baicalin at the concentrations of 20 and 40 μmol/L had an effect on decreasing IFN-γ, IL-5, IL-6 and on increasing IL-4 and IL-10. Conclusion Higher concentrations of baicalin show obvious effect on inhibiting RORC and IL23R expression, on decreasing IFN-γ, IL-5, IL-6 levels, and on increasing IL-4, IL-10 and TGF-β1 levels, which indicated that the therapeutic mechanism of baicalin in relieving ulcerative colonic inflammation is related with the regulation of immune function.

Objective To investigate the relationship between molecular subtypes of breast cancer and postoperative loco-regional recurrence (LR) in early breast cancer patients with 1-3 positive axillary lymph nodes (pN1) and to improve the individualized indications for post-mastectomy radiotherapy (PMRT)in these patients.Methods A total of 547 patients with pT1-2 N1M0 breast cancer,who received mastectomy between December 1998 and December 2009 in Sun Yat-sen University Cancer Center,were retrospectively analyzed.None of them received adjuvant radiotherapy after mastectomy.The patients were divided into luminal A group,luminal B group,HER-2-overexpressing group,and triple-negative group according to the molecular subtypes of breast cancer determined by immunohistochemistry and fluorescence in situ hybridization.The patients in different groups were compared in terms of LR rate (LRR) and LR-free survival (LRFS),and the risk factors for LR were analyzed in combination with clinical and pathological features.The Kaplan-Meier method was adopted to calculate LRR and LRFS;the Logrank test was used for survival difference analysis and univariate prognostic analysis.The Cox proportional hazards model was used for multivariate prognostic analysis.Results The luminal A group,luminal B group,HER-2-overexpressing group,and triple-negative group accounted for 30.0％,48.6％,9.3％,and 12.1％,respectively,of all the patients.The follow-up rate was 97.1％ ;334 patients were followed up for at least 5 years,and 127 were followed up for at least 10 years.Univariate analysis showed that,compared with the luminal A group,the HER-2-overexpressing group and triple-negative group had significantly higher 5-year LRRs (19.0％ vs 5.3％,x2 =4.28,P =0.026; 14.9％ vs 5.3％,x2 =5.02,P =0.015) and significantly lower LRFSs (73.5％ vs 91.1％,x2=7.27,P=0.005;80.6％ vs 91.1％,x2=4.77,P=0.021).Multivariate analysis revealed that HER-2 overexpression,triple-negative phenotype,age of ≤ 35 years,and stage pT2 were poor prognostic factors for survival (LRR and LRFS) (x2 =2.29,2.08,18.22,and 6.86,P =0.020,0.016,0.001,and 0.005;x2 =1.90,1.41,8.58,and 3.94,P=0.006,0.025,0.002,and 0.039).The 10-year LRRs of patients with 0,1,and ≥2 of the above risk factors were 4.3％,14.1％,and 31.9％,respectively (x2 =28.03,P =0.000).Conclusions Molecular subtyping is helpful for individualized evaluation of LR risk in early breast cancer patients with 1-3 positive axillary lymph nodes (pN1).PMRT should be recommended for the patients with 2 or more risk factors for LR.

All this accords with the regulation of pharmacopedia in vitro release.

Objective: To explore the preventive effect and possible molecular mechanism of dietary supplementation of N-carbamylglutamate (NCG) in the implantation of carbon disulfide (CS₂) into embryo implantation disorders. Methods: embryo implantation disorder model was established by single intraperitoneal exposure to CS₂ on the 3rd, 4th, and 5th days after pregnancy. Endometrial tissues were collected for 24h after exposure to CS₂ for western-blot and immunohistochemical staining. Results: The number of embryo implantation was increased in NCG+CS₂ group, compared with CS₂ alone group. Day 4 of pregnancy when CS₂-exposed after 24 h, the expression of pAKT protein in NCG+CS₂ group was significantly increased (P<0.05), the expression level of pAMPK protein in NCG+CS₂ group was significantly decreased, compared with CS₂ alone group, respectively. Immunohistochemical results showed that pAKT, pAMPK, AKT and AMPK proteins were expressed in luminal epithelial cells, glandular epithelial cells and stromal cells of endometrium; Day 4 of pregnancy when CS₂-exposed after 24 h, deep staining of ATK and pAKT protein in NCG+CS₂ group, the AMPK and pAMPK protein staining became lighter. Conclusion Dietary supplementation of NCG can interfere with the embryo loss induced by CS₂ by altering the total amount of AKT/AMPK molecules.

AIM: To detect the effect of conjunction matrigel with mammary fad pat(MFP)implantation on the tumorigenesis, proliferation, apoptosis and metastasis of Her2 positive and negative breast cancer model. METHODS: The Her2 positive BT 474 and Her2 negative MDA-MB 231 breast cancer cells were injected into MFP of nude mice with or without matrigel to establish breast cancer model. The tumor volume was measured every 3 d. Followed up for 30 d after implantation, the nude mice were killed and the tumors and associated organs were dissected for pathological sectioning and staining with hematoxylin and eosin. The time of tumor formation and the tumorigenesis were determined after implantation. The tumor volume and metastasis rate were calculated and compared with each other. The proliferation and apoptosis of Her2 positive and negative tumors were also determined. RESULTS: Matrigel and MFP implantation technology shortened the time of tumorigenesis significantly(P<0.01). The tumorigenesis rate of BT 474 and MDA-MB 231 breast cancer cells did not show any different(P>0.05). The metastasis rate of MDA-MB 231 breast cancer cells were improved from 25.0% to 37.5%(P<0.05). CONCLUSION: Matrigel and MFP implantation can be combined to shorten the time of tumor formation by two kinds of breast cancer cells, and improve the metastasis of Her2 negative MDA-MB 231 cells. Using matrigel does not show any effect of proliferation and apoptosis on Her2 positive and negative breast cancer cells.

Objective:To investigate the efficiency and pharmacoeconomics of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) for mobilization of peripheral blood stem cells (PBSCM) in patients with multiple myeloma (MM).Methods:The data of 91 patients with newly treated MM who were hospitalized in the First Hospital of Jilin University and Institute of Hematology & Blood Diseases Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College from January 2015 to October 2017 were retrospectively analyzed. According to the patient's wishes, a high-dose chemotherapy combined with subcutaneous injection of PEG-rhG-CSF or recombinant human granulocyte colony-stimulating factor (rhG-CSF) was used for stem cell mobilization in 42 and 49 patients, respectively. The number of mononuclear cells (MNC) and CD34 + cells collected after mobilization, the maximum absolute neutrophil count (mANC), the cost of mobilization, and the engraftment time of white blood cells and platelets after transplantation were compared between the two groups. Results:The median number of MNC collected after mobilization in the PEG-rhG-CSF group and rhG-CSF group were 5.86×10 8/kg [(1.08-24.54)×10 8/kg] and 6.61×10 8/kg [(0.83-33.80)×10 8/kg], and the difference was not statistically significant ( U = 883.00, P = 0.245); while the median number of CD34 + cells collected after mobilization in the PEG-rhG-CSF group was higher than that in the rhG-CSF group [5.56×10 6/kg (0.94-19.90)×10 6/kg and 4.82×10 6/kg (1.12-14.61)×10 6/kg], and the difference was statistically significant ( U = 732.00, P = 0.038). The median number of mANC during mobilization in the PEG-rhG-CSF group was lower than that in the rhG-CSF group [20.50×10 9/L (7.26-61.30)×10 9/L and 32.08×10 9/L (6.92-69.99)×10 9/L], and the difference was statistically significant ( U = 490.00, P = 0.001). After autologous stem cell transplantation (ASCT), the time-to-recovery of white blood cell count (WBC) to 1.0×10 9/L in the PEG-rhG-CSF group was shorter than that in the rhG-CSF group [(11.59±1.98) d vs. (12.93±2.83) d], and the difference was statistically significant ( t = -2.395, P = 0.019), and the time-to-recovery of platelet count (Plt) to 20.0×10 9/L in the PEG-rhG-CSF group was also shorter than that in the rhG-CSF group [(12.86±2.62) d vs. (14.80±5.47) d], but the difference was not statistically significant ( t = -1.749, P = 0.085). The total mobilization cost of the PEG-rhG-CSF group was not statistically different from that of the rhG-CSF group [(21 405.47±7 365.98) yuan vs. (22 976.83±10 264.34) yuan, t = -0.721, P = 0.474]. Conclusions:PEG-rhG-CSF combined with high-dose chemotherapy is an effective option for PBSCM in MM patients, and its mobilization cost is equivalent to rhG-CSF. Therefore, PEG-rhG-CSF may be a better choice for PBSCM in MM patients.
