Abstract： Objective　To investigate the distribution and antimicrobial resistance profile of the bacterial strains isolated from blood cultures in neonatal septicemia children of Neonatology Department, the First People's Hospital of Chuzhou during Jan. 2017-Dec. 2021, in order to guide clinical rational drug use. Methods　The distribution and the results of antimicrobial susceptibility tests and characteristics of the pathogenic bacteria isolated from blood culture samples in neonatal septicemia children in the First Hospital of Chuzhou from Jan. 2017 to Dec. 2021 were retrospectively analyzed. The results were analyzed with WHONET 5.6 software, according to the Clinical and Laboratory Standards Institute (CLSI) 2021 breakpoints. 　Results　A total of 189 strains were isolated from the 4 538 sample of blood cultures, the positive rate was 4.2%, including 59(31.2%) Gram-negative bacterial strains, 130 (68.8%) Gram-positive bacterial strains. The most frequently isolates were coagulase-negative staphylococci（64.0%), Serratia liquefaciens (15.9%), Escherichia coli (3.2%), Acinetobacter lwoffii (2.6%) and Delftia acidovorans (2.6%). The prevalence of methicillin-resistant isolates was 81.8%(99/121) in coagulase-negative Staphylococci and 25.0%（1/4） in Staphylococcus aureus. No staphylococcal strains were found resistant to vancomycin, quinupristin-dalfopristin or linezolid. The sensitivity of the antibacterial drug monitored by Serratia liquefaciens was 100.0%.Conclusions　Gram-positive bacterial are the main pathogen of neonatal septicemia, and is highly resistant to the common antibacterial drugs. The clinical should choose antibacterial agents reasonably according to drug sensitivity.

Objective To investigate the correlation between residual strength of neck and shoulder muscles and respiratory function in patients with cervical spinal cord injury.Methods From January,2015 to June,2016,the muscle strength of sternocleidomastoid,trapezius and deltoid was tested in 30 patients with cervical spinal cord injury five and 24 weeks after injury.Meanwhile,their neurological and pul-monary function was evaluated.Results There was correlation between the vital capacity and muscle strength of deltoid both five and 24 weeks after injury(r>0.806,P<0.05)in the patients intermittent without ventilation,and it was found in sense score five weeks after injury (r=0.914,P<0.01),motor score(r=0.979,P<0.001)and the muscle strength of trapezius(r=0.894,P<0.01)24 weeks after injury.Conclu-sion The residual strength of neck and shoulder muscles,especially of deltoid,plays an important role in the respiratory function in patients with cervical spinal cord injury.

OBJECTIVEIt has been shown that suboptimal DNA repair capacity is associated with cancer risk and that a poly(AT) polymorphism in XPC gene (XPC PAT) may influence DNA capacity. This study was designed to assess the relationship between XPC PAT polymorphism and susceptibility to lung cancer in the Chinese population.

METHODSXPC genotypes were determined by PCR methods in 509 healthy controls and 597 patients with lung cancer. The adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using multivariate logistic regression model.

RESULTSGenotype frequencies of XPC PAT among controls were 37.9% (PAT-/-), 49.7% (PAT+/-) and 12.4% (PAT+/+), respectively. They were not significantly different from those among lung cancer patients (42.1%, 46.7% and 11.2%, respectively; P = 0.37). Individuals carrying XPC PAT+/+ genotype were not at increased risk for lung cancer as compared with those with PAT+/- or PAT-/- genotype (adjusted OR, 0.8; 95% CI, 0.55 approximately 1.16). No interaction between XPC genotype and smoking was observed.

CONCLUSIONOur findings indicate that the XPC PAT polymorphism may not be associated with risk of lung cancer in the Chinese population.

OBJECTIVETo investigate the results of reconstruction of hypopharyngeal circumferential and cervical esophageal defects with free jejunal transfer.

METHODSRetrospective review of 112 patients who underwent pharyngoesophageal reconstruction with free jejunal interposition. Analysis was confined to the patients with advanced hypopharyngeal, esophageal or recurrent laryngeal squamous cell cancer. Kaplan-Meier method was used to identify the accumulative survival rate.

RESULTSThe free jejunal success rate was 94.6% (106/112). The pharyngocutaneous fistula rate and anastomoses narrow rate were 8.9% (10/112) and 12.5% (12/96) respectively. The perioperative mortality rate was 1.8% (2/112). Except 1 case of dead, 6 cases with flap failure and 2 cases with laryngeal preservation, other 103 cases had resumed oral feeding.

CONCLUSIONSThe success rate of free jejunal transplantation is high and free jejunal interposition is an ideal reconstruction method for patients who have hypopharyngeal circumferential and cervical esophageal defects after tumor resection.

OBJECTIVETo evaluate the efficacy of the distinct free flaps in reconstruction of different types of maxillectomy defects.

METHODSA retrospective reviews was performed of in 66 consecutive cases of reconstructions with free flaps for maxillary tumor ablation defects from October 1997 to June 2010. There were 43 patients who had recurrences after previous operations and 46 patients had accepted radiation therapy before. According to the classification of Brown's maxilla defect:10 cases were in class I, 13 in class II, 23 in class III and 20 in class IV. The reconstructive free flaps included 26 fibula flaps, 10 radial forearm flaps, 7 latissimus dorsi flaps, 7 rectus abdominis flaps, 7 anterolateral thigh perforator flaps, 5 deep inferior epigastric artery perforators, 2 latissimus dorsi/rib flaps and 2 iliac crest flaps. Postoperative features and functions were assessed in 29 patients.

RESULTSThe overall free flap success rate was 93.9% (62/66). Three rectus abdominis flaps and one fibula flap failed. There were 29 patients who received postoperative function assessment. Sixty-two percent of the patients restored to taking regular diets, 24 (82.8%) patients had normal language communication ability, and 25 (86.2%) patients were satisfied with their feature.

CONCLUSIONSRadial forearm flap was recommended to reconstruct the class 1 defect, fibula flap to class 2 or class 3 and preformatted flap to class 4.

OBJECTIVETo explore the anterolateral thigh (ALT) free flap in which the donor site is less noticeable and the morbidity is minimal for the reconstruction of head and neck defect.

METHODSA retrospective review was performed of 8 ALT flaps reconstructions for head and neck tumor ablation defects between Dec. 2003 and May 2005. Recipient sites were subdivided into pharyngeal wall (n = 3), oral tongue (n = 2), buccal mucosa (n = 1), base of tongue (n = 1) and skull base (n = 1). The operative technique of ALT flap was described.

RESULTSAll 8 free flaps survived. No complication was observed in the donor site, like wound dehiscence, weakness of the legs. The anatomy of the perforators were recognized as musculocutaneous pattern in all 8 cases. The size of the flap ranged from (4 to approximately 8) cm x (5 to approximately 10) cm. The average time of operation was 7 hours with a range of 5 to 10 hours. The average time cost for ATL flap harvest was 80 minutes with a range of 65 to 115 minutes.

CONCLUSIONSFree ALT flap is a reliable reconstruction technique for head and neck surgical defects. Because of the minimum donor site morbidity and the concealed site, this flap is the ideal choice for reconstruction of head and neck surgical defects.

Objective To understand the schistosomiasis control knowledge,attitude,and practice(KAP),and influenc-ing factors of behaviors among residents in Jiangsu Province,so as to provide the evidence for making effective health education and health promotion models. Methods The probability proportionate to size sampling(PPS)and multi-stage sampling meth-ods were adopted to sample the research objects. A questionnaire survey of schistosomiasis control KAP was conducted in the res-idents of 16 to 69 years old in schistosomiasis endemic areas of Jiangsu Province,and the results were statistically analyzed. Re-sults The total awareness rate of the participants was 95.98%for schistosomiasis control knowledge. The correct rates of atti-tude and practice were 89.06%and 77.43%,respectively. The awareness/correct rates of knowledge,attitude and practice re-duced in turns significantly(χ2=1282.96,P<0.01). The knowledge awareness rate of fishermen and boatmen was 90.98%, but their attitude correct rate was only 53.81%(χ2=120.52,P<0.01). The unconditional logistic regression analysis showed that with the education level increasing,their practice correct rate rose,and the participants with the college degree or above had a higher correct rate compared to illeterate ones(OR=6.411,95%CI:4.896-8.395). The practice correct rate of the fisher-men and boatmen was only 5.1%of the rate of the farmers(OR=0.051,95%CI:0.029-0.091). Conclusions The total aware-ness rate of basic knowledge of schistosomiasis prevention and control in the residents of Jiangsu Province has reached the re-quirements in the"National Schistosomiasis Control Long-term Planning Outline(2004-2015)",but the correct rate of behav-iors is low. The education level,occupation and residential areas affect the health behaviors of schistosomiasis prevention and control. Therefore,it is necessary to carry out targeted health promotion activities to promote the formation of healthy lifestyle and behaviors.
