Objective:To investigate the incidence of postoperative infection and its risk factors in patients with oral squamous cell carcinoma (OSCC), so that to provide a clinical basis for the prevention and management of postoperative infection in these patients.Methods:Ninety-seven patients pathologically diagnosed with OSCC who underwent surgical treatment in the Department of Oral and Craniomaxillofacial Oncology, Shanghai Ninth People′s Hospital, Shanghai Jiaotong University School of Medicine between December 2020 and March 2022 were included. This study was a clinical retrospective cohort study. The clinical characteristics and preoperative laboratory indicators of the included patients were collected. Based on the presence or absence of infection, the patients were divided into infection group and non-infection group. Chi-square test and independent samples t test were used for statistical methods. Binary logistic regression analysis was used to identify influencing factors for postoperative infection, and interaction terms were introduced to assess effect modification between variables. Results:Among the 97 patients, 46(47.42%) developed postoperative infections, of which 44(95.65%) were pulmonary infections. The proportion of hypertension in the infection group was 43.48%(20/46), which was higher than 23.53%(12/51) in the non-infection group, and the difference was statistically significant ( χ2=4.35, P=0.037). The preoperative glycosylated hemoglobin level in the infection group was 6.26%±0.85%, which was higher than that in the non-infection group (5.77%±0.57%), and the difference was statistically significant ( t=-2.81, P=0.007). Binary logistic regression analysis showed that male (odds ratio ( OR)=0.598, 95% confidence interval ( CI) 0.519 to 0.689, P<0.001), absence of diabetes ( OR=0.416, 95% CI 0.340 to 0.509, P<0.001), and absence of hypertension ( OR=0.647, 95% CI 0.569 to 0.735, P<0.001) were protective factors against postoperative infection. Age>60 years ( OR=1.159, 95% CI 1.031 to 1.304, P=0.014) and alcohol consumption ( OR=1.262, 95% CI 1.024 to 1.555, P=0.029) were risk factors for postoperative infection. Effect modification analysis found that males without diabetes ( OR=0.027, 95% CI 0.001 to 0.687, P=0.029) and the absence of both diabetes and hypertension ( OR=0.378, 95% CI 0.163 to 0.880, P=0.024) were also protective factors against postoperative infection. Conclusions:Risk factors for postoperative infection in OSCC include elder age, alcohol consumption, hypertension, and poor preoperative glycemic control. Therefore, clinical practice should enhance preoperative assessment, promote lifestyle modifications, optimize perioperative blood pressure management, implement glycemic control, and provide perioperative alcohol cessation interventions to reduce the risk of postoperative infection.

Objective:To explore the application of transverse tibial bone transport microangiogenesis combined with vacuum drainage in the treatment of diabetic foot ulcer.Methods:During April 2018 to April 2019, the clinical data of 87 patients with diabetic foot ulcer who were performed transverse tibial bone transport microangiogenesis combined with vacuum drainage in Changxing County Hospital of Traditional Chinese Medicine of Zhejiang Province were collected. In this study, there were 64 cases of males and 23 cases of females, aged 43-84 years, and average age was (64.5 ± 8.4) years. Right foots of 42 cases and left foots of 45 cases received operation. The diabetic course was (13.7 ± 6.2) years. The area of ulcer was 2.2 cm × 3.0 cm-7.5 cm × 5.7 cm. According Wagner grade, 16 case was Ⅱ garde, 38 cases was Ⅲ grade, 30 cases was Ⅳ grade, and 3 cases was Ⅴ grade. All patients were given treatment of anti-infection, monitoring of blood glucose and correcting hypoproteinemia. Ankle-brachial index(ABI) and Michigan Neuropathy Screening Instrument (MNSI) score were used to evaluate the recovery of peripheral vessel and nerve before operation and 3 months after operation. All patients were evaluated by angiography or color Doppler ultrasound after operation.Results:All patients were followed up for 3-24 months with average 13.6 months, and the wound surface were healed. At 3 months after operation, the ABI increased from 0.59 ± 0.19 to 0.89 ± 0.28, the scores of MNSI decreased from (5.81 ± 1.60) scores to (4.42 ± 1.25) scores, and there were significant differences ( P<0.05). The postoperative angiography and vascular ultrasound of 74 cases showed satisfied regeneration of micro-vessel. Conclusions:Transverse tibial bone transport microangiogenesis combined with vacuum drainage can rebuild the micro-vessel in the treatment of diabetic foot ulcer, and improve the wound surface healing. It is an effective method in treatment of diabetic foot ulcer.

Objective To analyze the infection status and variation tendency of chlamydia trachomatis (CT) ,Neisseria gonorrhoe-ae(NG) and ureaplasma urealyticum(UU) in female genital tract in northeast Sichuan province during 2005 -2012 to provide the laboratory basis for their diagnosis and treatment Methods The real-time fluorescent quantitative PCR (RT-PCR) was applied to detect the CT DNA ,NG DNA and UU DNA in 1 386 samples from female genital tract and the detection results were performed the statistical analysis .Results The total positive rate of these 3 kinds of pathogens was 62 .8% (871/1 386) .Among the simple in-fection ,UU had the highest positive rate(48 .0% ,665/1 386);the positive rates of CT and NG were only 2 .2% .In the mixed infec-tion ,the positive rate of CT + UU was highest(6 .5% ,90/1 386) ,while which of UU + NG ,CT + NG and CT+ NG+ UU was 2 .5% (35/1 386) ,0 .4% (5/1 386) and 1 .1% (15/1 386) respectively .In different age groups ,the positive rate in the age <20 years old group was 49 .3% ,while which in the age >20 years old groups were all more than 60% .The positive rate of the CT ,NG and UU pathogens in females was in continuous high level during 2005 -2012 ,and which totally showed an increasing tendency . Conclusion CT and UU are the main pathogens in female genital tract infection in this region ,and the positive rate of genital tract infection in females aged more than 20 years is higher ,the infection rate of these 3 kinds of pathogens demonstrates the increasing trend year by year ,so more attention should be paid to the detection of CT and UU in this group for guiding the clinicians to con-duct the diagnosis and treatment .
