OBJECTIVETo explore the effects of warm needling combined with Zhangmo decoction (see text) on endometrial receptivity in patients with clomiphene (CC)-induced ovulation.

METHODSOne hundred and sixty cases were randomly divided into a CC group (group A), a CC+ progynova group (group B), a CC+ Zhangmo decoction group (group C) and a CC+ Zhangmo decoction + warm needling group (group D), 40 cases in each one. In the Group A, CC alone was applied. In the group B, progynova was jointly used on the 8th day of menstrual cycle. In the Group C, Zhangmo decoction was jointly used on the 5th day of menstrual cycle. In the group D, based on treatment of the Zhangmo decoction, warm needling was applied at Guanyuan (CV 4), Zhongji (CV 3) and Zigong (EX-CA 1) etc. The endometrial thickness and type, pulsatility index (PI), resistance index (RI), ratio of S/D on day of human chorionic gonadotropin (HCG) and pregnancy rate were observed in fou groups.

RESULTSThe PI, RI and S/D in the group C and D were obviously lower than those in group A and B (all P < 0.01). The endometrial thickness was (7.7 +/- 1.49) mm in group B, (8.2 +/- 1.54) mm in group C and (8.9 +/- 1.51) mm in group D, which were significantly different from (6.4 5 +/- 1.26) mm in the group A (all P < 0.01) also there was a significant difference between group C and D (P < 0.05). The rate of endometrial type A was 65.0% in the group D, which was significantly higer than 27.5% in the group A, 32.5% in the group B and 35.0% in the group C (all P < 0.01). The pregnancy rate was 30.0% in the group D, which was obviously higher than 12.5% in the group A, 15.0% in the group B and 17.5% in the group C (P < 0.05). The endometrial thickness and rate of endometrial type A in the pregnant were obviously higher than those in the non-pregnant (both P < 0.01) while PI, RI and S/D was lower than those in the non-pregnant (P < 0.01, P < 0.05).

CONCLUSIONWarm needing combined with Zhangmo decoction could improve endometrial thickness, morphology and uterine spiral artery to improve pregnancy rate, which has superior effect to clomiphene, clomiphene combined with progynova and clomiphene combined with Zhangmo decoction.

Background Age-related cataract is one of the common causes of blindness.Although the pathophysiology of age-related cataract is far from clearly understood,it is well accepted that DNA damage plays an important role in the disease pathogenesis.Objective The purpose of this study was to quantitatively evaluate the DNA damage in peripheral lymphocytes of age-related cataract.Methods A cross-sectional study was carried out.This study complied Declaration of Helsinki and approved by Ethic Committee of Affiliated Hospital of Nantong University.Written informed consent was obtained from each subject.Two hundred and eleven patients with agerelated cataract and 147 normal subjects were enrolled from a “ Jiangsu Eye Study:Funing 2011 Eye Disease Epidemic Survey”.All the subjects aged from 50 through 80 years with matched age and gender between the two groups.The percentage of tail DNA and Olive tail moment (OTM) were detected by comet assay to assess the extent of DNA damage in peripheral lymphocytes.Statistical analyses were performed with SPSS 17.0 software,and the differences of the percentage of tail DNA and OTM were compared between the age-related cataract group and normal control group by independent sample t test as well as among the 50-59 years group,60-69 years group and ≥70 years group by one-way analysis of variance.Results Comet assay showed a round lymph cell with the clear border in the normal group;while in the age-related cataract group,the cell was bigger with a comet-like tail.The percentage of tail DNA and OTM in peripheral lymphocytes were (21.75 ± 3.51) ％ and 6.54 ± 1.65 in the age-related cataract group,and those in the normal control group were (9.31 ±3.60)％ and 2.18 ± 1.10,respectively,with significant differences between them (t =32.67,P =0.00 ; t =28.02,P =O.00).In the 50-59 years subgroup of the age-related cataract group,the percentage of tail DNA and OTM in peripheral lymphocytes were (20.04±2.86) ％ and 5.92± 1.14,and in the 60-69 years subgroup of the age-related cataract group,the percentage of tail DNA and OTM in peripheral lymphocytes were (20.77 ±2.93) ％ and 6.13 ± 1.14,which were significantly reduced in comparison with (22.79 ± 3.67)％ and 6.95±1.91 of the ≥70years subgroup(TailDNA％:q=2.75,P=0.00; q=2.02,P=0.00;OTM:q=1.03,P =0.02 ; q =0.82,P =0.00).Conclusions The pathogenesis and development of age-related cataract probably is associated with DNA damage.

OBJECTIVETo investigate the DNA and chromosome damage in peripheral blood lymphocyte of workers occupationally exposed to formaldehyde (FA).

METHODSAll 151 workers occupationally exposed to FA from two plywood factories and 112 workers without occupational FA exposure working in a machine manufactory were recruited into this study. Comet assay and cytokinesis-block micronucleus technique was used to evaluate the DNA and chromosomal damage of peripheral blood lymphocyte. The air FA samples were collected with SKC 224-PCXR8 air samplers. Gas chromatography was used to analyze the FA level. Personal information including occupational history, age, sex, smoking and drinking status was collected by the questionnaire.

RESULTSThe time weighted average concentration (TWA) of FA in the working environment of FA-exposed workers (range 0.10 - 7.88 mg/m(3)) was higher than those in controls (< 0.01 mg/m(3)). The olive tail moment (Olive TM) in low FA-exposed workers [3.03 (2.49 - 3.67)] was lower than that in high FA-exposed workers [3.95 (3.53 - 4.43)], but higher than that in controls [0.93 (0.78 - 1.10)], the differences were statistical significant (P < 0.05). Comet trail length in FA-exposed workers were significantly higher than that in controls [6.78 (6.05 - 7.60)], but no significant differences ware found between the high FA-exposed workers [12.59 (11.80 - 13.43)] and the low FA-exposed workers [11.25 (10.12 - 12.50)]. The frequency of micronuclei per 100 binucleated cells in low FA-exposed workers (0.41 +/- 0.25) was lower than that in high FA-exposed workers (0.65 +/- 0.36), but higher than that in controls (0.27 +/- 0.13), the differences were statistical significant (P < 0.05). The increased tendencies with the exposure levels were found in those three indices. In stratification analysis, the same results were found.

CONCLUSIONIn the current FA exposure levels, the DNA and chromosomal damage in peripheral blood lymphocyte might be induced by FA exposure, and be increased with the levels of exposure.

Objective To investigate the characteristics of infecting pathogens,their changes and antimicrobial susceptibilities on CAPD related peritonitis in our peritoneal dialysis(PD) center in the past 15 years.Methods Two hundred and six CAPD related peritonitis episodes in 145 patients from 2000 to 2005 were analyzed and compared with 109 episodes from 1991 to 2000.The causative pathogens,their antimicrobial susceptibilities and outcomes on CAPD related peritonitis from the two periods were retrospectively reviewed and compared.Results Culture negative rate decreased from 60.6% in 1990 s to 47.6% in the last five years (P=0.031 ).Among culture positive peritonitis episodes,the incidence of gram positive bacteria (GPB) peritonitis increased from 25.6% to 39.8% (P=0.059).This was mainly due to a significant increase in coagulase-neagative staphylococcus peritonitis,which significantly increased from 4.7% to 26.9% (P=0.01).Gram negative bacteria (GNB) peritonitis decreased slightly (44.2% vs 34.3%,P=0.322).The incidence of Klebsiella pneumoniae peritonitis significantly decreased (14.0% vs 3.7%,P=0.023),while Pseudomonas aeruginosa and Escherichis coli peritonitis rates slightly increased (4.7% vs 9.3%,P = 0.338;7% vs 18.7%,P=0.072).The decrease of fungal peritonitis rate was not significant (30.2% vs 17.6%,P= 0.123).The comparison of clinical outcomes showed an improvement of total recovery rate from 68.8% in 1990 s to 73.9% for 2000-2005 (P=0.09).The catheter removal rate decreased from 19.2% to 14.3% (P=0.238),and the mortality from 10.1% to 5.4% (P=0.118).In both periods,fungal peritonitis had the poorest results,which all the patients either withdrew from PD or died.Conclusions Compared with that in 1990 s,the culture positive rate for CAPD related peritonitis in 2000-2005 has been greatly improved.Coagulase-negative staphylococcus is the most common causative pathogen.The mortality and catheter removal rate have been markedly reduced in the last five years.Fungal peritonitis is the most important reason for patients' dropout.

Objective To evaluate the CT characteristics of osseous diversity in patients with sinonasal inverted papilloma (SIP) and to correlate these characteristics with the origins of tumors. Methods Sinonasal CT images of 28 patients were reviewed retrospectively to detect areas within which there was focal hyperastnsia. The correlation between the sites on the CT scans within which there was osseous diversity and the origin of the tumors in the surgery was analyzed. Results Surgical evaluation of 22 lesions with focal hyperostosis in CT images revealed that 20 of these lesions coincided with the actual origin of tumor. The focal hypernstosis on CT images corresponded to the actual tumor origin in 71.4% of cases. It denotes the origin of SIP could be predicted from the focal hyperostosis site. The origin of the other 2 cases were disaccored with the focal hypercstosis site, one case had the origin of uncinate process but hyperestosis of anterior middle turbinate, another case had the origin of superior turbinate but hyperostosis of uncinate process. Nine lesions of 28 patients had air sign, 21 lesions had bone absorption and destruction and 19 lesions had bone displacement in CT images. The pressure from tumor growth can induce varied bone destruction and displacement, the source of SIP can be estimated by the bone destruction site and displacement direction. Conclusions There has a relatively high concordance between the origin of the SIP and focal hyperostosis on CT, The source of SIP could be discerned indirectly by bone destruction and displacement, these conduce to asscss the disease before surgery and make peminent operation.

BACKGROUNDThe methods for the treatment of postcatheterization femoral arteriovenous fistulas (AVF-s) - simple observation, ultrasound guided compression, covered stents implantation and coil embolization have poor outcome. Surgery is the standard method for treatment of femoral AVFs, but it is a traumatic operation. In this study, we report the results of the treatment of postcatheterization femoral AVFs by simple prolonged compressing bandage.

METHODSTo treat iatrogenic femoral AVFs caused by transfemoral catheterization, prolonged binding with elastic or common bandage was applied in 16 cases. Catheterization was performed in 7 cases for radiofrequency current catheter ablation, in 4 for occlusion of congenital heart disease, in 3 for percutaneous coronary intervention, in 1 for coronary angiography and in 1 for right heart catheterization.

RESULTSAll iatrogenic femoral AVFs were healed after simple binding with elastic or common bandage for 4 - 46 days (mean (15 +/- 10) days). During the period of binding, local skins ulceration occurred at puncture site in two cases and femoral vein thrombus was found in one patient. During 6 - 24 months (mean (11.8 +/- 3.6) months) followup with colour Doppler ultrasonography, no recurrent arteriovenous shunting or other complications were observed.

CONCLUSIONThe results suggest that simple prolonged bandaging for postcatheterization femoral AVFs is an effective and economical procedure.

OBJECTIVETo compare the efficacy between subtotal colectomy with antiperistaltic cecoproctostomy and total colectomy with ileorectal anastomosis (TAC-IRA) for patients with severe refractory slow transit constipation(STC).

METHODSDuring 1999 to 2002, TAC-IRA was the preferred procedure for 20 STC patients in our department. From 2003 to 2005, 17 STC patients underwent subtotal colectomy plus antiperistaltic cecoproctostomy. Clinical data of the two groups were collected and compared retrospectively.

RESULTSThere were no significant differences in basic preoperative clinical data between the two groups. During the follow-up period, the time of daily defecation in the antiperistaltic cecoproctostomy group was less than that of TAC-IRA group (2.4+/-0.9 vs 3.4+/-0.8, P=0.0014), meanwhile the Wexner continence score was significantly lower in the antiperistaltic cecoproctostomy group (4.3+/-1.8 vs 5.8+/-1.9, P=0.0223). Barium enema after subtotal colectomy showed that residual ascending colon and cecum presented a sign of "reservoir".

CONCLUSIONSubtotal colectomy with antiperistaltic cecoproctostomy is a better method for appropriately selected patients with STC than TAC-IRA.

OBJECTIVETo study the seroprevalence of human T-cell leukaemia virus type I/II (HTLV-I/II) infection in adult population in the east coastal areas of Fujian and to explore the possible risk factors of HTLV-I/II.

METHODSA total number of 3259 blood samples from drug users, sexually transmitted disease (STD) patients, prostitutes and blood donors for serologic assays during 1999 to 2002, were collected. All samples were screened for HTLV-I/II antibody, using enzyme linked immunosorbent assay (ELISA) kits. All of the positive samples were confirmed by western blot (WB) kits. Statistical analysis was done by Epi software, and chi(2) test by Fisher's exact test. P value < 0.05 was considered statistically significant.

RESULTSThe overall seroprevalence rate of HTLV-I/II in healthy populations was 0.06% including, 0.32% in drug users, 0.58% in STD patients and prostitutes respectively. HTLV-II had not been found. The seropositive rates for HTLV-I in STD patients and prostitutes were significantly higher than the findings among healthy populations (P < 0.05). There were no different seroprevalence rates between drug users and healthy populations (P > 0.05). No significant changes in HTLV-I prevalence rates were found in the different age groups as well as in Fuzhou and Linde cities (P > 0.05).

CONCLUSIONThe result suggested that in the east coastal areas of Fujian province, HTLV-I was the main prevalent virus. The seroprevalence of HTLV-I was very low, with no HTLV-II. Neither age nor gender seemed to be HTLV-I risk factor in the east coastal areas of Fujian province, but the increase of exposure to sex might be one.

OBJECTIVETo explore the feasibility and functional outcome of antiperistaltic cecoproctostomy in colorectal reconstruction.

METHODSFifty-six patients who underwent antiperistaltic cecoproctostomy were retrospectively studied. Indications for antiperistaltic cecoproctostomy included slow transit constipation(n=44), synchronous colon cancer or colonic polyps(n=5), acute obstructing left colon carcinoma(n=4), and adult megacolon(n=3).

RESULTSShort-term postoperative complications included wound infections(n=5), 3 lymphatic leakages(n=3), and inflammatory small bowel obstruction(n=1). One month after antiperistaltic cecoproctostomy, the median frequency of daily bowel movement was 4.0(range, 2-6). After a median follow-up of 4 years(range, 1 month to 7 years), the median daily bowel frequency was 2.5(range, 0.5-4.0). Five patients suffered from long-term postoperative complications including small bowel obstruction(n=3), incision hernia(n=1), and mild cecal dilatation(n=1). The mean Wexner incontinence score was 4.2±1.1.

CONCLUSIONAntiperistaltic cecoproctostomy is safe and effective for colorectal reconstruction.

OBJECTIVETo investigate reversal effect of histone deacetylase inhibitor LBH589 alone or in combination with proteasome inhibitor bortezomib on drug resistance in acute myeloid leukemia (AML) and its mechanism.

METHODSEx vivo cultures of HL-60/ADM cells and fresh refractory AML cells were treated with LBH589, bortezomib or their combination at varying concentrations. Proliferation capacity, apoptosis rate and reversal of drug resistance were evaluated by MTT assay, dual staining of Hoechst 33342 and Annexin VFITC/PI by flow cytometry, and adriamycin uptake rate with proliferation inhibition, respectively. The change of signal pathway at protein level was analyzed by Western blot.

RESULTSSynergistic cytotoxicity was observed in the combination treatment with LBH589 and bortezomib against HL-60/ADM cells, as well as the fresh AML cells, the most powerful synergy being observed at 21 nmol/L LBH589 plus 12 nmol/L bortezomib, with CI values of 0.531 and 0.498, respectively by Calcusyn software analysis. Moreover, the accumulation of adriamycin in HL-60/ADM cells was increased more in combination treatment [(64.81 +/- 3.69)%] than in either LBH589 [(28.96 +/- 2.52)%] or bortezomib [(37.29 +/- 3.71)%] alone (P < 0.05), and so did the uptake rate of adriamycin being (64.81 +/- 3.69)%, (28.96 +/- 2.52)% and (37.29 +/- 3.71)% respectively (P < 0.05). The combination treatment induced multiple apoptotic molecules co-action and intracellular drug accumulation contributed to the synergistic cytotoxicity, including caspase activation, PARP cleavage, XIAP downregulation, p53-dependent suppression of Bcl-2 and MRP1 expression via the inhibition of phosphoinositide 3-kinase (PI3K)/Akt/nuclear factor-kappaB (NF-kappaB) signaling pathway.

CONCLUSIONSCombination treatment of drug resistant AML cells with LBH589 and bortezomib produces a synergistic effect of in creating sensitivity to chemotherapy. The mechanism may be mainly resulted from inhibition of PI3K/ Akt/NF-kappaB signaling pathway.
