Desmoid tumor(DT),a rare benign tumor sometimes with local invasion,is more frequently seen in patients with familial adenomatous polyposis(FAP) than in the general public,which might be associated with surgical trauma,genetic predisposition and hormonal factors.Fifty percent of FAP-associated DTs are intra-abdominal,usually present as non-tender,slowly growing masses.The symptoms include abdominal pain,vomiting and diarrhea,etc.Mesenteric DT can cause obstruction and ischemia of intestine,hydronephrosis and fistula.Diagnosis can be made through biopsy or CT scanning.Surgery should be considered for the abdominal wall DTs and medicine is the first choice for mesenteric DTs.Surgery should be chosen with caution.

Objective To investigate the level of uncertainty of illness and social support state in patients with prediabetes,and to discuss the correlation between the two.Methods 243 cases with prediabetes were analyzed by Uncertainty in Illness Scale and Social Support Rating Scale.Results There was a middle uncertainty in the elderly patients with prediabetes.The objective support,sabjective support,social support utilization degree and social support score were negatively related to the complexity of uncertainty(r--0.419,-0.433,-0.390 and-0.421,respectively,all P＜ 0.05).Conclusions Medical staff should evaluate the uncertainty in illness in elderly patients with prediabetes and conduct nursing intervention accordingly,in order to reduce the uncertainty,increase social support,and ultimately improve the quality of life.

Objective To clarify whether the NADPH oxidases (NOXs) family contributed to the reactive oxygen species (ROS) production and subsequent interstitial fibrosis in unilateral ureter obstruction (UUO) rats.Methods Male Wistar rats were randomly divided into sham operation group (n =8),sham operation + apocynin treatment group (n =8),UUO operation group (n =8) and UUO operation+apocynin treatment group (n =8).Either vehicle or apocynin (100 mg/kg per day) were given by gavage for 7 days after surgery.Rats were sacrificed at 7th day.ELISA was used to detect the activity of superoxide dismutase (SOD) and catalase (CAT),and the level of 8-iso-prostaglandin F2alpha (8-isoPGF2α) in renal tissue.Western blotting was used to detect the protein expressions of NADPH oxidase subunit NOX2 and NOX4,α-smooth muscle actin(α-SMA),collagen Ⅰ (COL-Ⅰ) and the level of ERK1/ 2 phosphorylation (p-ERK1/2).Results UUO rats with vehicle displayed increased oxidative stress,as measured by renal tissue 8-iso-PGF2α,accompanied with increased renal expression of NADPH oxidases (NOX2,1.5-fold and NOX4,1.7-fold,respectively),compared with sham-operated rats (P ＜0.05).Furthermore,vehicle treated UUO rats showed increased renal COL-Ⅰ and α-SMA levels,compared with sham-operated rats (P ＜ 0.05).ERK1/2 was also activated as detected by p-ERK1/2 expression in UUO rats with vehicle (P ＜ 0.05).Apocynin treatment significantly decreased renal tissue 8-iso-PGF2α level and expressions of NOX2 (-28.7％) and NOX4 (-31.0％) in UUO rats,respectively,compared with vehicle treated rats (P ＜ 0.05).And significant decrease of COL-Ⅰ (-26.4％) and α-SMA expression (-80.0％) were also observed (P ＜ 0.05).The activation of ERK1/2 in UUO rats was greatly inhibited by apocynin treatment (P ＜ 0.01).Despite the pronounced dysregulation of pro-oxidative NOXs family,no compensatory increase of antioxidative enzyme activities occurred.Conclusion The NOXs family contributes largely to the production of ROS and subsequent interstitial fibrosis after ureter ligation,and inhibition of the NOXs family may be a choice for preventing interstitial fibrosis.

A multiplex real-time PCR was developed to detect ctxA of Vibrio cholerae, gyrB and tdh of Vibrio parahaemolyticus simultaneously. The multiplex real-time PCR were evalidated by detection for the three genes in 47 toxigenic V. cholerae O1 and O139 strains (ctxA+; O1=3, O139=44), 25 non-toxigenic V. cholerae strains (ctxA-; O1=12, O139=6, non-O1 and non-O139=7), 116 V. parahaemolyticus strains with or without tdh (73 or 43) and 9 other bacteria strains. The specificity and sensitivity of the multiplex real-time PCR in detection for the ctxA and the tdh genes in the strains tested were both 100.0%, compared to the results by routine PCRs. In the detection for V. parahaemolyticus specific gyrB using the multiplex real-time PCR, all of 116 V. parahaemolyticus strains were positive, and 9 other strains and 72 V. cholerae strains were all negative. The multiplex real-time PCR is a sensitive, specific and quick assay not only for detecting virulence genes of V. cholerae and V. parahaemolyticus but also for identifying V. parahaemolyticus at species level. In addition, two real-time PCRs for detection of V. parahaemolyticus virulence genes trh1 and trh2 were also developed.

Objective To evaluate the feasibility of composite material of bone morphogenetic protein (BMP) and PLGA/TCP in repair of peri-porous-titanium bone defects in adult rabbits.Meth- otis The composite of PLGA/TCP scaffold with bovine BMP was made and implanted in distal bone de- fects peri-porous-titanium in femur of adult rabbits.The effect of BMP with PLGA/TCP on peri-prosthesis was evaluated by means of scanning electron microscope (SEM),energy dispersive X-ray analysis (EDX) and biomechanics.Results BMP with PLGA/TCP showed obvious peak of Ca and P of EDX in the pores of titanium in experiment group six weeks after operation and higher than that in control group (P＜0.05).Push-out test demonstrated that the bonding strength between the composite of HA coating/ porous titanium and bone was increased significantly with time (P＜0.05).In experiment group,at 6 and 12 weeks,peri-porous-titanium had higher shearing force compared with control group (P＜0.05). Conclusion BMP loaded with PLGA/TCP is a promising bone graft for bone defects in revision arthro- plasty,as indicates that bone induction of BMP plays an important role in biological stabilizaiton.

Objective: To investigate the creation of smoke-free environments in public places in Hangzhou City, so as to provide insights into effective implementation of the tobacco control policy. Methods: The party and government administrations at each level, medical institutions, educational places, restaurants and entertainment places, and open public places were enrolled. The creation of smoke-free environments was investigated in these places through undercover investigation with field observations and concealed photography by a third-party professional investigation company from November to December, 2022. The building of smoke-free environments (totally 60 scores) and no smoking indoors (totally 40 scores) were evaluated according to the Criteria for Scoring of Smoke-free Organizations in Hangzhou City. Results: Totally 909 places were investigated, and the comprehensive score of smoke-free environment building was (82.83±14.13) points. There were 285 party and government administrations with a comprehensive score of (84.19±12.85) points, 65 medical institutions with a comprehensive score of (90.35±6.95) points, 65 educational places with a comprehensive score of (83.43±16.81) points, 403 dining and entertainment places with a comprehensive score of (80.68±14.75) points, and 91 open public places, with a comprehensive score of (82.34±14.77) points. There were 397 places with standardized tobacco control tips at entrances (43.67%), 308 places with tobacco control signs posted as required (33.88%), 707 places that set outdoor smoking areas correctly (77.78%), 68 places with smoking paraphernalia (7.48%), 28 places with tobacco sales (3.08%). There were 732 places without signs of indoor smoking (80.53%), 850 places without indoor smoking (93.51%) and 24 places without dissuading from smoking (2.64%). Conclusion The indoor no-smoking is overall satisfactory in public places in Hangzhou City; however, standardizing no-smoking tips at entrances, standardizing the posting of no-smoking signs and assignment of tobacco control materials remain to be improved.

AIM: To investigate the immunologic mechanism of CXC chemokine ligand 10(CXCL10) and its receptor CXC chemokine receptor 3 (CXCR3 ) involved in the process of endometriosis (EM). METHODS: Serum samples were collected from 3 groups; EM patients without operation (n = 76) , EM patients with operation (n = 10) and the normal control persons (n =76). CXCL10 and CA12S concentrations were detected by means of ELISA and chemilumino-metry. Cell surface antigens on the activated PBMC - CD3 and CXCR3, as well as CXCR3 subgene - CXCR3A and CX-CR3B were tested by flow cytometry (FC) and RT - PCR when PBMC was separated from women with EM ( n = 10) and without EM (n = 10), and then activated. RESULTS: Serum CXCL10 concentrations between three groups were signifi-canly different (P < 0.05). Compared to normal control group, although the supernatant CXCL10 concentration and CD3~+ /CXCR3~+ PBMC number in EM group has no significant difference (P >0.05) , highly expressed CXCR3B in EM group rather than CXCR3A was observed. CONCLUSION: CXCL10 in women with EM is low, indicating that it plays a vital role in the process of EM and immune system of the women with EM is defected and impaired. The immunoreactivity of PBMC from both EM patients and normal person is same to activated signal, but the productions are different: PBMC in EM group mainly express CXCR3B but PBMC in normal person mainly express CXCR3A after activation, which may be one of the immune mechanisms that EM escapes from immunological lethal effect of the infected host.
