Objective To investigate the effect of partial body-weight supported treadmill training ( PBW- STT) on function of lower limbs, walk function, ADL performance and quality of life of hemiplegic patient induced by cerebral infarction. Methods A total of 132 cerebral infarction patients were divided into a control group (n = 69) and a training group( n = 63) randomly. Both groups accepted routine rehabilitation therapy, and the training group accepted PBWSTT at the same time in addition. Both groups were evaluated with regard to their walking ability, func- tion of lower limbs, ADL performance and their quality of life by using Functional Ambulation Category (FAC) , Fugl-Meyer assessment (FMA) , Barthel index (BI) and SF-36 before and after rehabilitation treatment. Results The function of lower limb, walking ability, ADL performance and the quality of life of both groups were improved significantly after treatment, and those in the training group were improved to a significantly greater extent than those in the control group ( P

BACKGROUNDIn China, esophageal squamous cell carcinoma (ESCC) and gastric cardia adenocarcinoma (GCA) share susceptibility loci, but different rates of multiple primary cancer and male/female ratio suggest the proportion of familial cancer is not equal.

METHODSThe percent of cases with a positive family history, median onset age, rate of multiple primary cancer, and male/female ratio associated with upper, middle, lower third ESCC and GCA were compared to reveal the proportion of familial cancer. The 7267 subjects analyzed constituted all ESCC and GCA cases in whom the cancer was resected with cure intention between 1970 and 1994 at the 4th Hospital of Hebei Medical University.

RESULTSA positive family history for cancer was most often associated with the multiple primary ESCC and/or GCA cases, e.g. with 42% of the males and 59% of the females. For upper, middle, lower third ESCC and GCA, the percent of cases with a positive family history decreased by 38.5%, 26.3%, 26.5%, and 11.2% in males (P < 0.000) and 25.0%, 22.3%, 23.9%, and 9.8% in females (P < 0.0001). Median onset age increased from 49, 52, 55, to 56 years old in males and from 50, 53, 55, to 56 years old in females ( both P < 0.0001) for upper, middle, lower third ESCC and GCA. Male/female ratio increased from 2.2, 2.1, 2.2, to 6.2:1 for upper, middle, lower third ESCC and GCA (P < 0.0001). For upper, middle, lower third ESCC and GCA, the percent of multiple primary cancers decreased from 21.2%, 2.3%, 2.2%, to 1.5% in males and from 14.3%, 2.4%, 3.4%, to 3.1% in females. The preponderance of males, smoking, drinking, or onset-age ≥ 50 years was significantly higher in GCA than in ESCC, and the difference in the rates of multiple primary cancers between the preponderant and the non-preponderant cases was significant in GCA, but not in ESCC, suggesting non-equal requirement for genetic susceptibility when environmental hazards did not exist.

CONCLUSIONSThe proportion of familial cancer in upper gastrointestinal carcinomas decreases by the primary site of upper, middle, lower third esophagus and gastric cardia. Considering familial and sporadic cancers differ in preventability, screening strategy and recurrence, our findings have basic and clinical implications.

OBJECTIVETo isolate antifungal compound from Paeonia suffruticosa, and to find the antifungal mechanisms by observing the ultrastructural modifications of yeasts in growth phase produced by 1,2,3,4,6-penta-O-galloyl-beta-D-glucose (PGG).

METHODSPeony (Paeonia suffruticosa) root bark (PRB) was separated by solvent extraction and purified by high performance liquid chromatography (HPLC) method using analytical and preparative reversed phase C18 column on the basis of bio-assay method. In order to investigate the antifungal mechanism of PGG, Yeasts were submitted to different concentrations [3 × minimum inhibition concentration (MIC), 0.3 × MIC] for 1 h under constant stirring at 30 °C, and transmission electron microscopy was performed.

RESULTSBased on the antifungal activity of PRB on Candida glabrata CBS138, the antifungal compound were isolated in ethyl acetate layer of PRB and identified as PGG by mass spectrometry, 1H nuclear magnetic resonance (NMR) analyses, with molecular weight of 940 and molecular formular as C41H32O26. Transmission electron microscopy showed that PGG degraded the cell wall envelope.

CONCLUSIONThe results suggest that PGG may be responsible for the antifungal activity of PRB by disrupting the structure of cell wall directly.

Objective To explore the distribution of water with high level arsenic and prevalence of arsenism along Huai'he River and the surrounding area of Hong'ze lake in Huai'an of Jiangsu. Methods Wate rsamples were collected and tested in 2008 from 18 villages of 6 towns according to history data in 3 counties like Xuyi,Jinhu and Hongze. Samples having arsenic level higher than 0.05 mg/L were investigated by epidemiological method and the patients were diagnosed by Standard of Diagnosis for Endemic Arsenism. Results All 5199 water samples were determined,and 260 water samples were exceeding the national drinking water quality level (0.05 mg/L) in 3 counties,the rates of exceeding diagnosis were 5.6%(247/4454),0.7%(4/597),6.0%(9/148) respectively. Total detected rate of endemic arsenic disease was 5.94%(128/2155). The detected rates of age group of 0 ～ ,20 ～,30 ～ ,40 ～ ,50 ～ ,60 ～ ,70 ～ ,80 ～ were 2.86%(1/35),2.11%(2/95),1.26%(3/239),3.10%(16/516),5.53% (32/579),10.07%(41/407),11.84%(27/228),10.71%(6/56) respectively. The detected rate of male (9.10%,78/857) was higher than that of female(3.85%,50/1298,χ~2 = 25.46,P < 0.01). Conclusions Huai'he River and the surrounding areas of Hong'ze lake like Xuyi,Jinhu and Hongze are identified existing endemic arsenic disease area. The prevention of arsenism should be strengthened in these areas.

OBJECTIVETo investigate the staphylococcal cassette chromosome mec (SCCmec) genotype and molecular epidemiological characteristics of healthcare-associated methicillin-resistant Staphylococcus aureus (HA-MRSA) in a large teaching hospital in China.

METHDOSFrom January 2012 to December 2012, a total of 71 nonduplicate HA-MRSA were collected in a teaching hospital in Changsha, China. SCCmec types were determined by multiplex PCR, and Panton-Valentine leukocidin (PVL) gene was detected by PCR. The homology among the tested isolates was determined using pulsed-field gel electrophoresis (PFGE).

RESULTSOf the 71 HA-MRSA isolates, 49 (69.0%) carried SCCmec III, 10 (14.1%) carried SCCmec IV, 3 (4.2%) carried SCCmec V and 3 (4.2%) carried SCCmec II; the remaining 6 isolates were not typeable by PCR. Compared with patients having SCCmec I/II/III MRSA infections, those with SCCmec IV/V MRSA infections had a significantly younger age and a similar duration of hospital stay before the first MRSA-positive culture and total hospital stay. PVL genes were strongly associated with SCCmec type IV/V MRSA infections. HA-SCCmec IV/V MRSA strains showed a greater susceptibility to rifampicin, gentamicin, levofloxacin, ciprofloxacin, and tetracycline than HA-SCCmec I/II/III MRSA strains. The 13 HA-SCCmec IV/V MRSA isolates formed one large group at the 55% similarity level. Three PFGE clusters with a similarity index of 85% or more were identified, and unique PFGE profiles were observed in 4 isolates.

CONCLUSIONThis is the first report of HA-MRSA isolates carrying SCCmec V in Chinese hospitals. SCCmec types IV and V MRSA clones have emerged in Chinese hospitals, which urges more rigorous surveillance of their spread in healthcare facilities in China.

BACKGROUNDThe infection rate of methicillin-resistant Staphylococcus aureus (MRSA) is increasing yearly due to the overprescription of antibiotics. Traditional Chinese compound medicines are less inclined to induce bacterial resistance in the clinical setting because of their multi-acting mechanisms. However, most current research is limited to bacteriostasis in vitro using single extracts or formulations. Plasma pharmacology is an in vitro method, using what is called "medicine serum". The aim of this study was to investigate whether the medicine serum of compound Qingre granules (QRKL) alone or in combination with antibiotics may treat MRSA infection in the clinic.

METHODSAn animal model of MRSA resistance was created by injecting rabbits with the standard strain of MRSA ATCC43300. Infected rabbits were treated with QRKL by intragastric administration. Sixty minutes after the last intragastric administration, serum was obtained from the rabbits by heart puncture to obtain what is termed "medicine serum". The minimum inhibitory concentration (MIC) of QRKL, medicine serum alone, or serum combined with antibiotics was assessed by agar dilution.

RESULTSwere compared with the growth of sixteen isolates of MRSA.

RESULTSThe MIC of QRKL to the standard strain ATCC43300 was 10.00 mg/ml. The MIC(90) of vancomycin was 1.00 microg/ml, which, when combined with QRKL, dropped to 0.50 microg/ml. The MIC(90) of cefuroxime alone was 512.00 microg/ml. This level also decreased to 256.00 microg/ml when combined with QRKL. The addition of QRKL thus significantly reduced the MIC of both cefuroxime and vancomycin compared with antibiotics alone (P < 0.01). The MIC(90) of vancomycin with medicine serum decreased to 0.50 microg/ml, and the MIC of vancomycin with medicine serum also descended compared with using vancomycin alone (P < 0.01).

CONCLUSIONSThe growth of MRSA can be inhibited by QRKL or medicine serum of QRKL in vitro. The addition of QRKL results in increased sensitivity of MRSA to vancomycin and this may provide a novel treatment for patients with MRSA infection.

Objective To observe distribution and antimicrobial resistance of pathogens from blood culture of chil-dren with leukemia,and study risk factors.Methods From September 2013 to November 2016,species and antimi-crobial resistance types of 131 strains of pathogens isolated from blood culture of 110 children in a pediatric hemato-logy ward were analyzed,childrens'clinical data were also analyzed statistically.Results 131 strains(5.23%)of pathogens were isolated from 2 505 blood culture specimens,gram-negative bacilli and gram-positive cocci accounted for 52.67% and 43.51% respectively,the top 3 pathogens were Escherichia coli(15.27%),Klebsiella pneumoniae (15.27%),and Staphylococcus hominis(12.98%). Gram-negative bacilli were highly resistant to ampicillin,ce-fazolin,ceftriaxone,and ampicillin/sulbactam,but sensitive to amikacin,cefoperazone/sulbactam,piperacillin/tazobactam,and carbapenems;gram-positive cocci had higher resistance to penicillin,oxacillin,erythromycin,and clindamycin,but were sensitive to tigecycline,linezolid,vancomycin,and quinupristin/dalfopristin. Univariate analysis showed that mixed infection,diarrhea,Pseudomonasaeruginosa infection,and Acinetobacterbaumannii in-fection were related to mortality due to bloodstream infection in children with leukemia.Conclusion Pathogens cau-sing bloodstream infection in children with leukemia is widely distributed,antimicrobial resistance rate is high,it is very im-portant to take active precaution and rational treatment according to antimicrobial susceptibility testing result.

OBJECTIVETo assess the clinical features and therapeutic efficacy of anterolateral thigh (ALT) flaps for the intraoral defects reconstruction.

METHODSThe clinicopathologic data of 67 cases with oral tumors were obtained from School of Stomatology, Nanjing University Medical Center from Dec. 2008 to Dec. 2010. All the patients underwent the simultaneous tumor resection and intraoral defects reconstruction with free anterolateral thigh flaps. The defects included the tongue, buccal, gingival, mouth floor, and so on. The descending branch of lateral femoral circumflex artery was anastomosed to the external maxillary artery or superior thyroid artery; the vein was anastomosed to the common facial vein or external jugular vein. The flaps were divided into three types: musculocutaneous ALT flap, fasciocutaneous ALT flap and thinned ALT flap.

RESULTSThere were 38 male patients and 29 female. The anterolateral thigh flaps included 35 musculocutaneous flaps, 17 fasciocutaneous flaps and 15 thinned flaps. The success rate was 98.5% (66/67). Partial necrosis happened in one case with diabetes, which healed after debridement and dressing. 1 flap was totally necrosis. Double venous anastomosis was performed in 41 flaps, and one venous anastomosis was performed in 26 flaps. 8 patients required operative exploration in the perioperative period including 6 flaps with thrombotic events (5 flaps were complete survival after the salvages, and 1 flap was failure) , 1 flap with hematoma, and 1 flap with twisting of perforator. The follow-up period ranged from 2 to 24 months( mean, 8.7 months). The result was satisfied. The donor sites were closed directly in all patients, and the wounds healed uneventfully.

CONCLUSIONSThe free anterolateral thigh flap is an ideal soft tissue flap for the intraoral defects reconstruction with good functional result at recipient area and less morbidity at the donor site.

OBJECTIVETo investigate the application of titanium mesh and free forearm flap for reconstruction of maxillary defect resulted from tumor resection.

METHODSFrom 2004 to 2008, 19 cases with maxillary tumor underwent tumor resection. The defects were reconstructed immediately with titanium mesh for bony defects and free forearm flap for oral mucosa defects.

RESULTS16 cases achieved satisfactory functional and cosmetic results. The speech assessment was good without oronasal reflux. The titanium mesh was exposed and infected in 3 cases. Then the meshes were taken out and the defects were covered with the forearm flap to close the oronasal fistula. The midface was slightly depressed with no functional morbidity.

CONCLUSIONSIt is simple and practical to reconstruct maxillary defect with titanium mesh and free forearm flap. Both the functional and cosmetic results are satisfactory.
