Objective: To observe the clinical efficacy of herb-partitioned spreading moxibustion at Baliao points plus climen for diminished ovarian reserve (DOR). Methods: A total of 60 patients with DOR were randomized into a spreading moxibustion group and a Western medicine group by the random number table method, with 30 cases in each group. The Western medicine group was treated with climen, starting from the 5th day of the menstrual cycle for 21 d. The spreading moxibustion group was treated with herb-partitioned spreading moxibustion at Baliao points on the basis of the medication in the Western medicine group, 1 h per time, once a week. The treatment was performed for 1 month as one treatment course in both groups, for 3 courses in total. The serum follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) in the patients were measured before and after treatment. The peak systolic velocity (PSV) and resistance index (RI) were also detected. The traditional Chinese medicine (TCM) symptom score was evaluated. The clinical efficacy was evaluated after treatment. Results: The total effective rate in the spreading moxibustion group was 93.3％, which was significantly higher than 80.0％ in the Western medicine group, and the difference between the groups was statistically significant (P<0.05). After treatment, the TCM symptom scores, the serum FSH levels, FSH/LH ratios and RI in both groups decreased, and the intra-group differences were all statistically significant (all P<0.05). The serum E2 level and PSV increased compared with those in the same group before treatment, and the intra-group differences were statistically significant (all P<0.05). After treatment, the TCM symptom score, the serum FSH level, FSH/LH ratio and RI in the spreading moxibustion group were lower than those in the Western medicine group, while the serum E2 level and PSV were higher than those in the Western medicine group, and the differences between the groups were statistically significant (all P<0.05). Conclusion: Herb-partitioned spreading moxibustion at Baliao points plus climen can produce valid therapeutic efficacy for DOR. It can improve the clinical symptoms, regulate serum hormone levels and increase ovarian blood perfusion, thus improving ovarian reserve function, producing more significant efficacy than climen alone.

OBJECTIVETo study the influence of human plasma exosomes-like vesicles on the regulatory function of macrophages.

METHODSThe exosomes-like vesicles were purified from healthy donors plasma with a series of high-speed centrifugation and ultrafiltration. Macrophages were derived from cultured human blood monocytes. The molecular markers of macrophages were assayed by FACS. After cultured with exosomes-like vesicles, the changes of macrophages cytoplasma Ca(2+), and related genes and proteins were assayed by FACS, RT-PCR and Western Blot, respectively.

RESULTSAfter cultured with exosomes-like vesicles, mean fluorescent intensity (MFI) of macrophages cytoplasma Ca(2+) was increased. The vesicles enhanced macrophages to express cytokines genes, the expression of IL-1β and TNF-α genes being increased by 0.85 and 1.69 times respectively at 2 h, and that of IL-6 gene 3.7 times compared with the control at 8 h. However, the vesicles inhibited the expression of macrophages IL-10 gene, had no influence on the Frizzled5 receptor expression and could induce CaMKII phosphorylation.

CONCLUSIONSExosomes-like vesicles can up-regulat macrophages expression of inflammatory cytokines genes, and increase the secretion of inflammatory cytokines by activating the Wnt5A-Ca(2+) signaling pathway.

OBJECTIVETo establish Biological Limit Value (BLV) for N, N-dimethylacetamide (DMAC).

METHOD201 workers in 3 spandex factories exposed to DMAC were recruited. Air samples were collected using personal air samplers, and urine samples from each works were collected at the end of shift at end of workweek. The urinary metabolite NMAC and air samples of DMAC were determined by gas chromatography (GC). Percentile and relative internal exposure (RIE) were analyzed and proposed a BLV for DMAC.

RESULTSThe number of workers who exposure to DMAC below OELs were 133 (66.2%) among 201 workers monitored. Geometric mean (range) concentration of DMAC in air was 19.4 (0.40 ∼ 300.12) mg/m(3), and that of NMAC in urine was 23.7 (1.30 ∼ 189.42) mg/g Cr. A linear correlation was found between the personal air DMAC and creatinine-adjusted NMAC levels in urine collected at the end of shift at end of workweek (F = 188.872, R(2) = 0.487,P < 0.001). The relationship can be described by the equation Log (NMAC mg/g Cr) = 0.685 + 0.455 log (DMAC mg/m(3)). According to the equation the current China OELs value of 20 mg/m(3) would lead to a mean NMAC concentration of 18.92 mg/g Cr. The 90th percentile biomonitoring result below 20 mg/m(3) 8-hour TWA is 23.9 mg MMAC mg/g Cr, and that of NMAC in urine calculated by relative internal exposure (RIE) was 19.0 mg/g Cr.

CONCLUSIONA BLV of 20 mg/g Cr NMAC in urine at the end of shift at end of workweek for DMAC was recommend by reference to official values from other countries.

OBJECTIVETo identify the exosomes-like vesicles from the plasma and study their biologic characteristics and regulatory effect.

METHODSThe exosomes-like vesicles were purified from healthy donors plasma with a series of high-speed centrifugations and ultrafiltration. Morphology was identified by transmission electron microscopy and biologic characteristics by Western blot and flow cytometry. CD4(+)T cells and CD4(+)CD25(+)CD127low Treg cells were purified from peripheral blood mononuclear cells (PBMCs) by Magnetic cell sorting. After exosomes-like vesicles cultured with CD4(+)T cells or CD4(+)CD25(+)CD127low Treg cells, cell proliferation and apoptosis were assayed. Phosphorylated β-catenin level in Wnt signaling by phosflow.

RESULTSExosomes-like vesicles from plasma were similar to previously described exosomes in shapes and size and expressed exosome marker proteins CD63 and CD81 as well as the MHC-II molecule, costimulatory molecules CD86 etc. After co-cultured with CD4(+) T cells, exosomes-like vesicles inhibited the proliferation of the T cells in a dose-dependent manner. After Treg cells cultured with exosomes-like vesicles for 14 days, the survival rate of the Treg cells was 57.07%, while that of the control Treg was 30.91%. Frizzled receptors 2, 3, 4and LRP6 gene mRNA expressed (the relative gray value was 48.50, 34.84, 23.85, 49.73) in the Treg cells by RT-PCR, and Wnt molecular expressed in exosomes-like vesicles. After Treg cells co-cultured with exosomes-like vesicles, the MFI of phosphorylated β-catenin decreased (from 20.06 ± 2.99 to 12.41 ± 2.08), and the expression of Bcl-2 mRNA was upregulated significantly (the relative gray value from 0.45 to 84.97).

CONCLUSIONSExosomes-like vesicles existed in human plasma and express immune regulatory molecules. They can suppress the proliferation of activated CD4(+) T cells induce their apoptosis and pro-long the survival of natural Treg cells via Wnt signaling pathway.

Objective: To observe the blood perfusion volume variation pattern in the body surface microcirculation at the Yuan-Primary and the Xi-Cleft points during the menstrual cycle in female college students with moderate constitution under normal physiological state of the uterus; to explore the specific laws of the body surface microcirculation at the Yuan-Primary and Xi-Cleft points in response to the uterine qi and blood changes under normal physiological conditions, and to provide the experimental basis for the specificity of acupoints reflecting the uterine function. Methods: Forty-three healthy and moderate constitution female college students with regular menstrual cycles, without dysmenorrhea and not yet giving birth were recruited. Bilateral Yuan-Primary points [Taichong (LR 3), Taibai (SP 3) and Taixi (KI 3)] and Xi-Cleft points [Zhongdu (LR 6), Diji (SP 8) and Shuiquan (KI 5)], belonging to the three yin meridians of foot and adjacent to the spinal cord segment of the uterus, were selected as the detection acupoints; the crossing point of the three yin meridians of foot [Sanyinjiao (SP 6)], the uterus-related meridian acupoint [Xuehai (SP 10)], the uterus-non-related meridian acupoint [Xuanzhong (GB 39)], and the non-meridian non-acupoint point were selected as the control points. The laser speckle blood flow imaging technique was used to monitor the blood perfusion volume in skin microcirculation at the above points at the menstrual, follicular, ovulatory, and luteal phases of the subjects. Results: The blood perfusion volume in the body surface microcirculation at the right Zhongdu (LR 6) at the ovulatory phase was higher than that at the menstrual, follicular and luteal phases (all P<0.05); there was no significant difference in the microcirculation blood perfusion volume at the other points among different phases (all P>0.05). Conclusion: The blood perfusion volume in the body surface microcirculation at Zhongdu (LR 6), the Xi-Cleft point of the Liver Meridian, shows a specific response to qi and blood changes in the uterus of women with moderate constitution.

OBJECTIVE To investigate toll-like receptor 4(TLR4)-related the regulation of Ornithog-alum caudatum extract(OCE)on inflammatory responses in lipopolysaccharide(LPS)activated macro-phages.METHODS Primary peritoneal macrophage,Raw 264.7,and THP-1 were incubated in 96-well plate for 24 h and treated with OCE of the concentration of 0-400 μg/ml for 4h.The viability of cells was measured by MTT assay.Specific concentrations of OCE were added into the medium of primary peri-toneal macrophage, Raw 264.7, and THP-1, respectively, then following with lipopolysaccharides (LPS). Cells were harvested and the total cellular protein and nuclear protein were extracted, and the protein content was determined using BCA protein assay Kit.The expressions of TLR4,inducible nitric oxide synthase(iNOS),cyclooxygenase 2(COX-2),α-inhibitor of NF-κB(IκB-α)and nuclear factor-κB (NF-κB)were assayed by Western blot.The expressions of interleukin-1α(IL-1α),interleukin-1β(IL-1β), interleukin-18(IL-18),and tumor necrosis factor-α(TNF-α)were measured by RT-PCR.RESULTS The results of MTT showed that OCE has no cytotoxicity in Raw 264.7 cells between 1.56 μg/ml and 400 μg/ml. Compared with normal group,the expressions of TLR4,iNOS,COX-2,NF-κB and IL-1α,IL-1β,IL-18, TNF-α,the level of nitric oxide(NO)were significantly increased by LPS stimulation,while OCE pretreat-ment reduced these increase induced by LPS. However, OCE pretreatment reversed the reduction of IκB-α after LPS stimulation.CONCLUSION OCE might suppress TLR4 expression and block the inflamma-tion process of NF-κB and iNOS,further decrease the expression of COX-2 and inhibit the release of inflammatory factors.

Ovarian cancer has become the most lethal gynecological tumor due to the difficulty in early diagnosis,the late stage when diagnosed and the high recurrence rate.Resistance to platinum-based anti-tumor chemotherapy drugs is an important reason for the poor prognosis of ovarian cancer.circular RNA(circRNA)is more stable than mRNA in cells due to its special structure,and it is involved in the regulation of the occurrence,development and chemotherapy resistance of a variety of tumors.circRNA can be used as a competing endogenous RNA(ceRNA)of miRNA to bind to proteins,and regulates the phenotypic polarization of macrophages,it can also be used as an exosomal circRNA to regulate the sensitivity of platinum resistance in ovarian cancer.circRNA is expected to be a new marker of platinum resistance and a new target for the treatment of platinum resistance.In order to further explore the relationship between circRNA and platinum resistance in ovarian cancer,this article summarizes the recent literature related to circRNA and platinum resistance in ovarian cancer.

Objective: To observe the clinical efficacy of auricular point pricking-bloodletting plus auricular point sticking therapy for acne vulgaris. Methods: A total of 66 patients with acne vulgaris were randomized into an observation group and a control group by the random number table, with 33 cases in each group. The observation group was treated with auricular point pricking-bloodletting plus auricular point sticking therapy, and the control group was treated only with auricular point sticking therapy. The treatments of both groups were performed twice a week, 4 weeks as a course of treatment, for 3 courses in total. The scores of skin lesions and dermatology life quality index (DLQI) scores were recorded before and after treatment to assess the clinical efficacy. Results: During the trial, there were 3 cases of drop-out both in the observation group and the control group. After 3 courses of treatment, the total effective rate of the observation group was 96.7％, while that of the control group was 76.7％. The difference between the two groups was statistically significant (P<0.05). The intra-group comparison showed that the scores of skin lesion and DLQI were both decreased with the increase of treatment times, that was, the scores were lower than those at the previous time point (allP<0.05). After 1, 2, and 3 courses of treatment, the scores of skin lesion and DLQI of both groups were statistically different from those of the same group before treatment (allP<0.05). At every time point during the treatment, the scores of skin lesion and DLQI of the observation group were lower than those of the control group, and the differences between the two groups were statistically significant (all P<0.05). Conclusion: Auricular point pricking-bloodletting plus auricular point sticking has a better curative effect than auricular point sticking therapy alone in the treatment of acne vulgaris, and has a time-effect correlation.

Objective To analyze the prevalence and influencing factors of anxiety and depression among pregnant women in Jianyang City. Methods Convenience sampling method was used to select 322 pregnant women in Jianyang Maternal and Child Health Hospital of Jianyang City. The depression and anxiety of the participants were measured with self-rating anxiety scale(SAS) and self-rating depression scale(SDS)，and the degree of social support was measured with social support rating scale (SSRS). Pearson correlation analysis was used to analyze the relationship between anxiety, depression and social support. The chi square ( 2) test and the non-conditional Logistic regression model were used to analyze the influencing factors of anxiety and depression. Results Anxiety rate and depression rate of pregnant women in Jianyang city were 5.3% and 5.6% respectively. There was a negative correlation between anxiety, depression and social support (P<0.05). Absence of prenatal examination (OR=4.554, 95% CI: 1.063-19.510) was a risk factor for anxiety among pregnant women in Jianyang City. Late pregnancy (OR=5.381, 95% CI: 1.422-20.363) and medium degree of social support (OR=4.150, 95% CI: 1.198-14.375) were risk factors for depression among pregnant women in Jianyang City. Junior high school (OR=0.015, 95% CI: 0.001-0.275), high school or technical secondary school (OR=0.004, 95% CI: 0.001-0.128), junior college or above (OR=0.053, 95% CI: 0.003-0.851) were protective factors for depression. Conclusions The prevelance of anxiety and depression in pregnant women cannot be ignored. It is important to carry out mental health intervention according to the above factors.
