Background and purpose:The time from ifrst onset of symptoms or signs to a deifnitive diagnosis is deifned as diagnostic interval (DI). The relation of DI to other clinicopathological parameters andthe impact of DI on prognosis of patients with triple-negative breast cancer (TNBC) remain unclear.This article plans to make an intensive study of these questions.Methods:The clinical records of a series of 83 consecutively presenting unselected patients referred to the Shanghai Sixth People’s Hospital with diagnosed TNBC between September 2009 and September 2015 were retrospectively reviewed. Clinical and pathological factors included were investigated by univariate analysis using the Kaplan-Meier method, the factors associated with prognosis were further evaluated by multivariable analysis with Cox progression model.t-test and Kruskal-Wallis test were used to study the correlation between DI and other characters.Results:DI: stage T3>T1 (P=0.01), stageⅢ>Ⅱ (P=0.03) andⅠ (P=0.01). Compared with patients of DI≥3 months, the <3 months group had earlier age (P=0.028) and TNM stage (P=0.035). T stage, N stage, neoadjuvant chemotherapy, TNM stage and DI are inlfuencing factors of overall survival (OS). Age, T stage, N stage, TNM stage, menstrual status and neoadjuvant chemotherapy are inlfuencing factors of progression-free survival (PFS). TNM staging is an independent inlfuencing factor for OS and PFS.Conclusion:Patients with later disease stage were more likely to have a longer DI; The shorter DI, the earlier age and stage of disease; DI is the inlfuence factor of OS; TNM stage is an independent inlfuencing factor for OS and PFS.

Objective:Dipeptidyl peptidase I(DPPI),a lysosomal cysteine protease for serine proteases activation,highly expressed in granule immune cells.This study used collagen induced arthritis(CIA) rat model to investigate the effects of Triperygium Wilfordii Polyglucoside(TWP) on DPPI activity and the pharmacological mechanism in RA treatment.Methods:Rats were divided into four groups randomly,the blank control group,the CIA model group,the high dose (5.0 mg/100 g body-weight) and low dose(2.5 mg/100 g body-weight)treatment group.Bovine collagen-Ⅱ plus complete Freund′s adjuvant injected twice in rats.Physical assessments were carried out.12 days post-injections,the rats of treatment group were intragastric administered with TWP every day.The rats were killed after two week administrations.Serum and synovial membrane homogenates were collected and DPPI activity was detected by fluorescence substrate.Joint HE staining and cell counting were carried out,Zymography was used to detect the MMP-2/9 activity in synovial fluids.Total protein in synovial membrane homogenates were measured by BCA method.Results:TWP could reduce the number of CIA synovial tissue mast cells,inhibited DPPI activity in the synovial fluids and in serum.The expression levels of MMP-2/9 activity and synovium total protein content were also reduced by TWP.Conclusion:Triperygium Wilfordii Polyglucoside has inhibitory effects on DPPI activity on CIA rats,which might be the one of the pharmacological mechanisms in RA treatment.

OBJECTIVETo observe the effect of Tongxie Yaofang (TY) on the number of mast cells (MCs) and the expression of cytokines in rats with visceral hypersensitivity, and to explore roles of TY in treating visceral hypersensitivity and its possible mechanism.

METHODSTotally 30 male adult Sprague Dawley (SD) rats were randomly divided into the blank control group, the model group, and the TY treatment group, 10 in each group. The irritable bowel syndrome (IBS) rat model was established by combining colorectal distention with restraint stress in the TY treatment group and the model group. The visceral hypersensitivity was assessed by abdominal withdrawal reflex (AWR). From the 2nd day of successful modeling, rats in the treatment group were admiministered with TY at the daily dose of 4 g/kg for 4 successive weeks. Equal volume of normal saline was given to rats in the model group for 4 successive weeks. No treatment was given to rats in the blank control group. Four weeks later the number of MCs was counted by using toluidine blue staining. The expression of interleukin-4 (IL-4) and interleukin-9 (IL-9) both in colonic mucosa and serum were measured by enzyme linked immunosorbent assay (ELISA), and the expression of protease-activated receptor type 2 (PAR-2) was detected by Western blot.

RESULTSCompared with the blank control group, the visceral sensitivity was significantly elevated, the number of MCs in the ileocecal junction increased, and the expression of IL-4, IL-9, and PAR-2 in serum and the colonic mucosa significantly increased (P < 0.05). Compared with the model group, the visceral sensitivity significantly decreased, the number of MCs reduced, and the expression of PAR-2 in the colonic mucosa significantly reduced (all P < 0.05), and the expression of IL-4 in colonic mucosa and IL-9 in serum were obviously reduced in the TY treatment group (P < 0.05).

CONCLUSIONTY might improve the visceral hypersensitivity by acting on MCs related cytokines and reducing degranulation of MCs.

Objective To investigate the clinicopathological features,treatment and prognosis of leiomyomatosis peritonealis disseminata (LPD).Methods A total of 10 patients suffered from LPD after laparoscopic uterine myomectomy were collected in the First Affiliated Hospital of Zhengzhou University from September 2012 to September 2016,and all clinical database were retrospectively analyzed.Results (1)Clinical features:the age of 10 cases was 25-50 years old,and 8 cases of them were in child-bearing age,while 2 cases were in perimenopausal period.Of 10 cases,2 cases manifested as discontinuous lower abdominal pain,and the other cases were seen the doctor for the examinations found tumors of pelvis or abdomen.All 10 cases had a history of laparoscopic uterine myomectomy under went power morcellation with an average of (4.0±2.2) years (range 1.3 to 8.1 years),2 cases of them had a history of oral hormone treatment after the first myoma morcellation.(2) Treatment methods and postoperative pathologic diagnosis:during intraoperative exploration,LPD nodules were most distributed in Douglas pouch (10 cases),and next in mesentery (7 cases),abdominal peritoneum (6 cases) and omentum majus (4 cases),etc.Seven of the 8 cases of child-bearing age were performed laparoscopic LPD nodules removal,1 case gone combined with laparotomy and resecting LPD nodules;2 cases in perimenopausal period done laparotomy oophorotomy and resected all LPD nodules and omentum.(3) Postoperative relapse and reproductive outcomes:the follow-up time of all cases was 2.8 years,and no recurrence was found during the follow-up period;2 cases had natural conception and term vaginal birth during the follow-up period.Conclusions LPD is mainly related to iatrogenic planting and spreading,which is a benign disease and characterized by multiple smooth muscle nodules throughout abdominopelvic cavity,and the nodules of LPD is commonly located in Douglas pouch,mesenteric and omentaum majus,etc.The preferred method of LPD should be individual operative treatment according to different situations,and in which patients may be have better prognosis.

Objective To investigate the clinical characteristics, risk factors and pathogenic disposition of candida urinary tract infections in intensive care unit(ICU)patients. Methods A retrospective review and analysis of clinical information and urine culture of 83 ICU patients with the candida urinary tract infections. Results All patients had severe underlying diseases one or more complication and/or concomitant diseases were existed at the same time. All of the patients previously used broad-spectrum antibiotics and received invasion in diagnosis and therapy: indwelling urinary catheters, mechanical ventilation, incision of trachea, deep artery or vein operation with catheters indwelling, surgical operation and indwelling drainage tube (96.39%, 95.18%, 69.89%, 46.99%, 43.37%, 33.73%, respectively). In all the patients, 62.65% patients were elder. Hospitalization days of 54.22% patients staying in ICU were above 31 days. Mortality rate was in 39.76%( 33 cases ). C.tropicalis(55.91%) and C.albicans(35.48%) were the major pathogens. Seventy-four cases( 89.16%)were infected by one candida specie, and 9 cases( 10.84% )were infected by two or three candida species. The positive blood culture was found in 9 cases ( 10.84% ) also. Conclusions The ICU patients with severe underlying diseases and high risk factors may have candida urinary tract infections easily. C.tropicalis and C.albicans are the most common pathogens. Some candiduria is the evidence of candidemia.

Objective To evaluate the effect of tripterine on hydrochloric acid-induced acute lung injury(ALI)in mice.Methods Eighteen pathogen-free healthy adult male ICR mice,aged 7-9 weeks,weighing 25-30 g,were divided into 3 groups(n=6 each)using a random number table:control group(group C),hydrochloric acid-induced ALI group(group ALI)and tripterine group(group T).ALI was induced by a single intratracheal instillation of hydrochloric acid 2 ml/kg(pH 1.5)via a 24-gauge angiocatheter inserted into the trachea in pentobarbital sodium-anesthetized mice.Tripterine 3 mg/kg was injected intraperitoneally once a day for 3 consecutive days,and then the model was established in group T.The mice were sacrificed at 6 h after instillation,and lung specimens were obtained for microscopic examination and for determination of the levels of tumor necrosis factor-alpha(TNF-α),interleukin-6(IL-6),macrophage migration inhibitory factor(MIF)and myeloperoxidase(MPO)in lung tissues.Results Compared with group C,the levels of TNF-α,IL-6,MIF and MPO were significantly increased at 6 h after instillation in ALI and T groups(P<0.01).Compared with group ALI,the levels of TNF-α,IL-6,MIF and MPO were significantly decreased at 6 h after instillation in group T(P<0.01).The pathological changes of lung tissues were significantly attenuated in group T compared with group ALI.Conclusion Tripterine can attenuate hydrochloric acid-induced ALI in mice.

OBJECTIVETo systematically evaluate acupuncture as a treatment for male infertility.

METHODSWe searched Chi na Biology Medical Database (CBM), Wan Fang Medical Information System, China National Knowledge Infrastructure (CNKI), VIP Information Resource System (VIP), and PubMed for published literature on acupuncture as a treatment for male infertility on May 1 2014. Based on the Standards for Reporting Interventions in Clinical Trials of Acupuncture (STRICTA), we evaluated the quality of the reports, conducted meta-analysis on the identified studies via RevMan5.2, and assessed the quality of the evidence in the literature by Grading of Recommendations Assessment, Development, and Evaluation (GRADE).

RESULTSA total of 12 studies involving 2,177 patients were included, the quality of which was evaluated as mediocre. With regard to the cure rate, acupuncture was comparable to traditional Chinese medicine (TCM) (P > 0.05) but better than Western medicine (RR = 4.00, 95% CI 1.63 to 9.82, P < 0.01) while acupuncture + TCM was better than either TCM (RR = 1.77, 95% CI 1.20 to 2.60, P < 0.01) or Western medicine used alone (RR = 2.73, 95% CI 1.51 to 4.93, P < 0.01), and acupuncture + Western medicine was better than Western medicine alone (RR = 1.88, 95% CI 1.17 to 3.02, P = 0.01). The combined use of acupuncture, ear pressure, TCM, and Western medicine showed a higher cure rate than the combination of TCM and Western medicine (RR = 3.45, 95% CI 2.90 to 4.11, P < 0.01). In therapeutic effectiveness, acupuncture was comparable to TCM (P > 0.05) but superior to Western medicine (RR = 1.41, 95% CI 1.12 to 1.71, P < 0.01), acupuncture + TCM was superior to either TCM (RR = 1.14, 95% CI 1.05 to 1.23, P < 0.01) or Western medicine alone (RR = 1.43, 95% CI 1.22 to 1.67, P < 0.01), and acupuncture + Western medicine was superior to Western medicine alone (RR = 1.25, 95% CI 1.05 to 1.49, P = 0.01). In improving sperm concentration, acupuncture was as effective as TCM (P > 0.05) and sham acupuncture (P > 0.05) but outdid Western medicine (RR = 27.00, 95% CI 24.27 to 29.73, P < 0.01) and acupuncture + TCM outdid either TCM (RR = 14.65, 95% CI 7.58 to 21.72, P < 0.01) or Western medicine alone (RR = 1.04, 95% CI--1.43 to 3.51, P > 0.05). In improving grade a sperm, acupuncture exhibited a similar effect to TCM (P > 0.05) and sham acupuncture (P > 0.05), and acupuncture + TCM was more effective than TCM alone (RR = 7.78, 95% CI 3.51 to 12.23, P < 0.01) but equally effective as Western medicine (P > 0.05). In elevating the level of grade a + b sperm, acupuncture + TCM excelled either TCM (RR = 11.00, 95%, CI 3.17 to 18.82, P < 0.01) or Western medicine alone (RR = 12.22, 95% CI 6.87 to 17.57, P < 0. 01), while acupuncture produced a comparable effect with sham acupuncture (P > 0.05). As for the quality of the included studies, only 3 conclusions of the 23 meta-analyses were assessed to be of average quality, while the others of poor or extremely poor quality. Therefore, the recommendation grade of the conclusions was low.

CONCLUSIONFor the treatment of male infertility, acupuncture is reported to be equally effective as TMC and more effective than Western medicine, and its effectiveness is enhanced when applied in combination with either TCM or Western medicine. Acupuncture is distinctively efficacious in improving sperm quality. Nevertheless, the overall quality of the included studies is low.

Objective To investigate the prevalence of diabetes and impaired glucose regulation in high risks community residents in Songjiang District of Shanghai, and to explore the risk factors affecting their blood glucose metabolism, providing effective suggestions for improving community diabetes prevention and treatment. Methods Questionnaire, physical examination and laboratory testing were used to collect information on the basic characteristics and blood glucose levels of 21 035 residents in Songjiang District who were assessed to be at high risk of diabetes. Results A total of 3 008 people with impaired regulation and 2 241 patients with diabetes were detected.The detection rates were 14.3% and 10.6%, respectively.It was found that as the residents′ age was higher, their education level was lower, high-risk factors for them were numerous, and their detection rates of diabetes and impaired sugar regulation were higher.It was found that age, gender, history of impaired glucose regulation, relatives with type 2 diabetes, hypertension, dyslipidemia and overweight/obesity were all factors influencing blood glucose metabolism (P < 0.05). Conclusion Blood glucose screening in high-risk population of diabetes is helpful for the early detection of diabetic patients and those with impaired glucose regulation.It is necessary to strengthen the attention of population at risk of diabetes and take appropriate interventions.

OBJECTIVETo explore the relationship between the single nucleotide polymorphisms (SNPs) of rs12979860 and rs8099917 in IL28B gene and the response to interferon treatment in hepatitis B e antigen (HBeAg)-positive patients with chronic hepatitis B patients.

METHODSPeripheral blood samples were collected from 82 HBeAg-positive patients with chronic hepatitis B receiving interferon treatment, including 38 with favorable response to the treatment and 44 without response. IL28B gene was amplified from the chromosomal DNA, and rs8099917 SNP was genotyped based on PCR-RLFP and rs12979860 SNP by sequencing.

RESULTSIn the responsive patients, the distribution frequencies of TT and TG+GG genotypes and allele G in SNPrs8099917 were 81.6% (31/38), 18.4% (7/38), and 9.2% (7/76), as compared to the frequencies of 97.7% (43/44), 2.3% (1/44), and 1.1% (1/88) in nonresponsive patients, respectively. The frequencies showed significant differences between the responsive and nonresponsive patients (P=0.014 for genotypes and P=0.025 for allele G). The distribution frequencies of CT genotypes and allele T in SNPrs12979860 showed no differences between the responsive and nonresponsive patients (P<0.05).

CONCLUSIONrs8099917 SNP is probably associated with the response to interferon treatment in HBeAg-positive patients with chronic hepatitis B, and Allele G may be predictive of the treatment success.
