RESUMO
OBJECTIVE: To observe the effect of moxibustion pretreatment at different time on serum hormone levels in diminished ovarian reserve (DOR) rats, so as to explore its protective mechanisms. METHODS: Forty female SD rats were randomly divided into control, model, moxibustion-1 (moxibustion was given 4 weeks before modeling), moxibustion-2 (moxibustion was given 2 weeks before modeling and 2 weeks from the 1st day on after modeling ) and moxibustion-3 (moxibustion was given 4 weeks from the 1st day on after modeling) groups (n=8 rats in each group). The DOR model was established by gavage of Tripterygium Glycosides (75 mg/kg) once daily for 14 days. Grain-moxibustion was applied to "Shenshu" (BL23) and "Guanyuan" (CV4) for 7 cones, 5 times a week for 4 weeks. The body weight and the ovary weight were recorded for calculating the ovarian index. The levels of serum anti-mullerian hormone (AMH), follicle stimulating hormone (FSH), estradiol (E2), androgen (T) and dehydroepiandrosterone (DHEA) were detected by ELISA. RESULTS: After modeling, ovarian index and serum AMH levels were obviously decreased (P<0.05), and the levels of serum FSH, E2, T and DHEA were significantly increased in contrast with the control group (P<0.05). Following intervention and compared with the model group, the serum FSH and DHEA levels of each moxibustion group were significantly reduced (P<0.05), the AMH levels significantly increased and E2 and T contents significantly decreased in the moxibustion-2 and moxibustion-3 groups (P<0.05). The serum FSH, E2 and T contents in moxibustion-2 group were obviously lower than those of the moxibustion-1 and moxibustion-3 groups (P<0.05). CONCLUSION: Moxibustion pre-treatment can improve ovarian reserve function in DOR rats, while the effect is different with different intervention time, and the best intervention time is pre-occurrence and early stage of DOR.
RESUMO
<p><b>OBJECTIVE</b>To observe the multiple symptom distribution, severity and quality of life of female pelvic floor dysfunction(FPFD) patients with constipation as chief complaint.</p><p><b>METHODS</b>One hundred FPFD patients with constipation as chief complaint from Speciaty Outpatient Clinic, Pelvic Floor Center of Nanjing Municipal Hospital of Traditional Chinese Medicine between September 2015 and February 2017 were retrospectively enrolled in this study. A comprehensive medical history questionnaire survey and systematical evaluation of severity and quality of life of these patients with constipation was conducted. Constipation scoring system scale (CSS) and patient-assessment of constipation quality of life questionnaire (PAC-QOL) were applied to evaluate the constipation. Other scales included: (1)pain visual analogue scale (VAS) and short form-36 questionnaire (SF-36): if combined with chronic functional anal rectal pain; (2) international consultation on incontinence questionnaire-short form (ICIQ-SF) and urinary incontinence quality of life questionnaires (I-QOL):if combined with urinary incontinence; (3) fecal incontinence severity score scale (Wexner-FIS) and fecal incontinence quality of life questionnaire (FI-QOL):if combined with fecal incontinence.</p><p><b>RESULTS</b>The mean age of 100 FPFD patients was (57.9±13.9) (24-89) years and the mean disease course was (7.0±8.2)(0.5-40.0) years. Seventy-five cases (75%) were complicated with anal pain, 70 with urinary incontinence, 37 with rectocele, 19 with nocturia, 11 with urinary frequency, 10 with defecation incontinence. Complication with only one symptom was observed in 20 cases (20%), and with two or more symptoms was observed in 80 cases (80%). Pelvic floor relaxation syndrome patients were dominant (58 cases, 58%). The severity of constipation (CSS) was 6-22 (13.89±3.79) points and the quality of life (PAC-QOL) was 45-133 (87.13±18.57) points in FPFD patients. VAS and SF-36 of patients combined with chronic functional anal rectal pain were 1-8 (3.0±1.9) points and 14.4-137.0(71.5±31.4) points respectively. ICIQ-SF and I-QOL of patients combined with urinary incontinence were 1-17 (6.1±3.6) points and 52-110 (90.0±15.8) points respectively. Wexner-FIS and FI-QOL of patients combined with fecal incontinence were 1-11 (4.4±3.0) points and 52-116 (83.4±23.3) points respectively.</p><p><b>CONCLUSIONS</b>The symptoms of FPFD patients with constipation as chief complaint are complex. They are mainly complicated with anal diseases, then urinary incontinence, and mostly with more than 2 symptoms. Their quality of life is poor.</p>

OBJECTIVE: To explore the needle insertion parameters of deep acupuncture at Baliao points for clinic and teaching. METHODS: A retrospective analysis of 100 cases of prone pelvic CT from January to June 2016 in Nanjing Hospital was carried out. The 3 D images were scanned with continuous 5 mm slice thickness. The optimum needle angle is defined as the angle of the needle along the central axis of sacral anterior and posterior hole, and the angle between the needle body and the skin surface and the center line of the body was observed. The effect needle depth is defined as the thickness of the sacral back soft tissue plus 1/2 sacral depth, to observe the best needle angle of deep acupuncture parameters of Baliao points. RESULTS: For deep acupuncture at Baliao, the oblique thorn method should be used with the needle-point toward the inner bottom. The best insertion angle between needle body and skin surface is: Shangliao(BL 31) (61.04±12.15)°, Ciliao(BL 32) (57.57±10.01)°, Zhongliao(BL 33) (58.25±8.69)°, Xialiao(BL 34) (54.39±10.94)°. The optimum angle of insertion between the needle body and the posterior midline of the human body is: BL 31 (24.54±6.21)°, BL 32 (18.58±7.76)°, BL 33 (17.36±7.90)°, BL 34 (30.73±9.45)°. The effective insertion depth show a decreasing trend: BL 31 (58.16±12.43) mm, BL 32 (44.57±11.55) mm, BL 33 (33.96±10.74) mm, BL 34 (31.13±10.94) mm. The effective depth is positively correlated with BMI, and has no correlation with gender and weight. CONCLUSIONS: The study of the parameters of needle insertion should be taken into account both clinical efficacy and safety, and CT three-dimensional reconstruction can accurately, rationally and scientifically perform acupoint anatomical measurements.

In this paper, we described an ultra-low power, wearable ECG system capable of long term monitoring and mass storage. This system is based on micro-chip PIC18F27J13 with consideration of its high level of integration and low power consumption. The communication with the micro-SD card is achieved through SPI bus. Through the USB, it can be connected to the computer for replay and disease diagnosis. Given its low power cost, lithium cells are used to support continuous ECG acquiring and storage for up to 15 days. Meanwhile, the wearable electrodes avoid the pains and possible risks in implanting. Besides, the mini size of the system makes long wearing possible for patients and meets the needs of long-term dynamic monitoring and mass storage requirements.

Although human telomerase catalytic subunit (TERT) has several cellular functions including telomere homeostasis, genomic stability, cell proliferation, and tumorigenesis, the molecular mechanism underlying anti-apoptosis regulated by TERT remains to be elucidated. Here, we show that ectopic expression of TERT in spontaneously immortalized human fetal fibroblast (HFFS) cells, which are a telomerase- and p53-positive, leads to increases of cell proliferation and transformation, as well as a resistance to DNA damage response and inactivation of p53 function. We found that TERT and a mutant TERT (no telomerase activity) induce expression of basic fibroblast growth factor (bFGF), and ectopic expression of bFGF also allows cells to be resistant to DNA-damaging response and to suppress activation of p53 function under DNA-damaging induction. Furthermore, loss of TERT or bFGF markedly increases a p53 activity and DNA-damage sensitivity in HFFS, HeLa and U87MG cells. Therefore, our findings indicate that a novel TERT-bFGF axis accelerates the inactivation of p53 and consequent increase of resistance to DNA-damage response.

<p><b>OBJECTIVE</b>To discuss the effect of acupuncture for treatment of chronic functional constipation (CFC).</p><p><b>METHODS</b>Ninety cases were treated with acupuncture. The following two groups of acupoints were used alternatively once every other day. The acupoints in the first group were Tianshu (ST 25), Qihai (CV 6), Shangjuxu (ST 37) etc., and Zhongliao (BL 33), Xialiao (BL 34), Dachangshu (BL 25) etc. in the second group, electroacupuncture was used at Zhongliao (BL 33), Xialiao (BL 34), Tianshu (ST 25) and Shangjuxu (ST 37), once a day, 10 times constituting one course. The defecation frequency, difficulty degree of defecation, defecation time, endless sensation of defecation, stool quality and awareness of defecation were observed and the Patient Assessment of Constipation Quality of Life (PAC-QOL) was evaluated by constipation patients' diaries.</p><p><b>RESULTS</b>The scores of defecation frequency, difficulty degree of defecation, defecation time, endless sensation of defecation, stool quality, awareness of defecation and PAC-QOL were obviously improved after treatment (all P < 0.01). The total effective rate was 67.7% (61/90). The effect of acupuncture for chronic functional constipation in different dynamic mechanism was different. The effect of slow transit constipation (STC) was better than that of spastic pelvic floor syndrome (SPFS) (P < 0.05), and the effect of constipation caused by irritable bowel syndrome (IBS-C) was better than that of SPFS and relaxant pelvic floor syndrome (RPFS) (both P < 0.05). Fifty-two cases were effectively followed up. Three cases were cured, 6 cases were remarkably effective, 23 cases were effective and 20 cases were ineffective after 1 month of treatment. Three cases were cured, 5 cases were remarkably effective, 16 cases were effective and 28 cases were ineffective after 3 months.</p><p><b>CONCLUSION</b>The effect of acupuncture for CFC with exact etiology, disease location and classification diagnosis is definite, but different dynamic mechanism has different effect. The treatment programs for SPFS and RPFS need to be optimized to improve the therapeutic effect.</p>

Objective To study a scoring method for assessing function status of cardiovascular system quantitatively. Methods First, exercise heart rate variability (EHRV) was obtained from the primary dynamic electrocardiogram (ECG) recorded during exercise testing. Then appropriate entropy, relative complexity, and other three parameters extracted from poincare dispersed-dot plot were extracted from the EHRV. Discriminant analysis was used to classify two extreme groups.Results Based on the values of two groups from the discriminant formula, a scoring formula was proposed and four ranks were divided according to different score domains. A novel scoring method was established. To validate the proposed scoring method, 60 middle-aged hypertensives, 50 elder subjects and 110 young healthy subjects were examined and scored. Conclusion Scores of 220 subjects are consistent with their real health status. The proposed scoring method reflects the status of the subject's cardiovascular system effectively.
