Objective To understand the prevalence characteristics of influenza and changes of influenza virus strains,and provide reference for the prevention and control of influenza in the province.Methods Surveillance da-ta about influenza in Hunan Province from 2014 to 2023 were exported from China Influenza Surveillance Informa-tion System.Differences in the percentage of influenza-like illness(ILI)cases(percentage of influenza-like cases[ILI％]in outpatient and emergency department visits)among different years and different populations,as well as the positive rate of influenza virus in ILI specimens were compared.Results From 2014 to 2023,over 2.65 million cases of ILI were reported,with an ILI％of 4.70％.ILI％among different years presented statistically significant differences(P＜0.001).People aged 0-14 years old were the main population with ILI,accounting for 82.90％.The positive rate of influenza virus in ILI specimens was 14.14％,the positive rate of influenza virus among diffe-rent years and age groups were both significantly different(both P＜0.001).The main prevalent influenza strains from 2014 to 2023 included types A(H1N1),A(H3N2),B(Victoria),and B(Yamagata),alternating among di-fferent years.However,type B(Yamagata)strains were not detected from 2020 to 2023.There were basically two influenza prevalence seasons every year,namely winter-spring and summer.Conclusion People＜15 years old are the main population of influenza,and the prevalence peaks are in winter-spring and summer.From 2021 to 2023,the prevalence alternates mainly among 3 types:A(H1N1),A(H3N2),and B(Victoria).

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective To analyze the effect of low-dose methylprednone sodium succinate combined with erythromycin in the treatment of Mycoplasma pneumoniae infection with elevated lactate dehydrogenase(LDH)in children.Methods Children with Mycoplasma pneumoniae pneumonia(MPP)complicated with elevated LDH were divided into control group and treatment group by random number table method.The control group was given erythromycin treatment,and the treatment group was given low-dose methylprednisolone sodium succinate combined with erythromycin treatment.Clinical efficacy and clinical symptom disappearance time were recorded in both groups.Pulmonary X-ray signs,immune function[T cell subsets(CD4+,CD8+,CD4+/CD8+)],immunoglobulin(Ig)A,IgM and serum LDH were compared between the two groups before and after treatment,and the adverse drug reactions of treatment were observed.Results There were 51 cases in control group and 51 cases in treatment group.The total effective rate in treatment group was 96.00％,which was significantly higher than 81.63％in control group(P＜0.05).The fever abatement times in treatment group and control group were(4.22±0.87)and(5.46±0.98)d;cough disappearance times were(6.31±0.98)and(7.49±1.10)d;disappearance times of pulmonary rales were(7.36±1.14)and(8.61±1.23)d,all with significant difference(all P＜0.05).After treatment,the patchy infiltrating shadow sign rates in treatment group and control group were 2.00％and 16.33％;the bronchial wall thickening sign rates were 4.00％and 18.37％,all with significant difference(all P＜0.05).After treatment,IgA levels in treatment group and control group were(0.55±0.11)and(0.68±0.12)g·L-1;IgM levels were(0.90±0.19)and(1.18±0.21)g·L-1;LDH levels were(229.45±10.30)and(240.18±11.17)U·L-1,all with significant difference(all P＜0.05).The total incidence of adverse drug reactions in treatment group and control group were 6.00％and 4.08％respectively,without significant difference(P＞0.05).Conclusion Erythromycin combined with low-dose methylprednone in systemic treatment of children with MPP and elevated LDH has a significant efficacy,and it can promote the reductions of inflammation and immune disorders and accelerate the disease outcomes,and it is safe and reliable.

Objective: To evaluate the efficacy and safety of neoadjuvant chemotherapy combined with programmed death-1 (PD-1) antibody in operable, borderline or potentially resectable locally advanced esophageal squamous cell carcinoma(ESCC) in the real world. Methods: The study retrospectively analyzed 28 patients with operable or potentially resectable locally advanced ESCC patients treated with preoperative chemotherapy combined with PD-1 inhibitor in Nanjing Drum Tower Hospital, Affiliated Hospital of Nanjing University Medical School from April 2020 to March 2021. According to the clinical TNM staging system of the 8th edition of the American Joint Committee on Cancer, there were 1, 15, 10, 1 and 1 case of stage Ⅱ, Ⅲ, ⅣA, ⅣB and unknown stage respectively. The treatment was two cycle of dual drug chemotherapy regimen including taxane plus platinum or fluorouracil combined with PD-1 antibody followed by tumor response assessment and surgery if the patient was eligible for resection. Results: Of the 28 patients, 1, 2, 3 and 4 cycles of chemotherapy combined with PD-1 antibody treatment completed in 1, 21, 5, and 1 patient, respectively. Objective response rate (ORR) was 71.4% (20/28), and disease control rate (DCR) was 100% (28/28). The incidence of adverse events exceeding grade 3 levels was 21.4% (6/28), including 3 neutropenia, 1 leukopenia, 1 thrombocytopenia and 1 immune hepatitis. There was no treatment-related death. Of the 23 patients underwent surgery, R0 resection rate was 87.0% (20/23), 13 patients had down staged to the T1-2N0M0 I stage, the pCR rate was 17.3% (4/23), and the pCR rate of primary tumor was 21.7% (5/23). Four patients received definitive chemoradiotherapy. One patient rejected surgery and other treatment after achieved PR response. Conclusion: Neoadjuvant chemotherapy combined PD-1 inhibitor is safe and has high efficacy in operable, borderline or potentially resectable locally advanced ESCC, and it is a promising regimen.

Objective: To investigate the clinical effect of disk-up sinus reamer (DSR) in maxillary sinus floor elevation with maxillary sinus septum. Methods: Twenty-four patients were included between January 2019 to January 2020 in Department of Oral Implantology, The Affiliated Hospital of Qingdao University. There were 10 males and 14 females with the age of (39.3±11.7) years old (range 22-56 years). Pre-operative(T0) cone-beam CT (CBCT) was taken for measurement and analysis. All patients were divided into group E (easy situations, septum located anterior to the zygo-matic process), group M (moderate situations, septum located pos-terior to the zygo-matic process) and group D (difficult situations, sagittally oriented septum). The maxillary sinus floor was grafted through the crestal approach by DSR and implants were placed simultaneously. Permanent repair was performed 6-8 months after operation. All patients underwent CBCT before surgery, after surgery immediately (T1), 6 months after surgery(T2), 1 year after surgery(T3), 2 year after surgery(T4). The residual bone height (RBH) and the vertical bone height (VBH) were analyzed. The mucosal perforation rate, implant survival rate were counted. Results: All the 24 patients completed the Maxillary sinus lift surgery successfully and 24 implants were placed simultaneously. All patients had no headache, dizziness. The mucosal perforation rate was 0. The survival rate of implants during the healing period was 100%(24/24). The RBH was (5.81±2.56) mm pre-operation, the VBHT1, VBHT2, VBHT3 and VBHT4 were (11.82±1.09), (10.98±0.52), (10.66±0.44) and (10.40±0.33) mm, respectively. The differences between the groups by pairing test were statistically significant (F=187.70, P0.001), expect VBHT3 and VBHT4 (P=0.071). Bone resorption and remodeling mainly occurred 1 year after surgery. One patient developed peri-implantitis 18 months after surgery. Conclusions: With the RBH of implant site>2 mm and existence of maxillary sinus septum, using DSR for sinus floor elevation has a high success rate. It can obtain enough bone height and complete the simultaneous implantation to form a good osseointegration. The DSR is simple, safe and controllable, and can shorten the operation time.

OBJECTIVE: To observe the clinical efficacy of targeted sealing with high viscosity bone cement and secondary injection of low viscosity bone cement in the treatment of OVCFs patients with the fracture lines involved vertebral body margin. METHODS: The elderly patients who underwent vertebroplasty for osteoporotic vertebral compression fractures from January 2019 to September 2021 were selected as the screening objects. Through relevant standards and further CT examination, 56 patients with fracture lines involving the anterior wall or upper and lower endplates of the vertebral body were selected for the study. There were 21 males and 35 females, aged from 67 to 89 years old with an average of (76.58±9.68) years. All 56 patients underwent secondary injection of bone cement during operation. Only a small amount of high viscosity cement was targeted to seal the edge of the vertebral body for the first time, and low viscosity cement was injected to the vertebral bodies during second bolus with well-distributed. The operation time, bone cement volume and bone cement leakage were recorded, and the pain relief was evaluated by visual analogue scale (VAS). RESULTS: All patients were followed up for more than 3 months and the surgeries were successfully complete. The operation time was (50.41±10.30) min and the bone cement volume was (3.64±1.29) ml. The preoperative VAS was (7.21±2.41) points, which decreased significantly to (2.81±0.97) points 3 days after operation(P<0.05). Among the 56 patients, 2 cases(3.57%) had bone cement leakage, 1 case leaked to the paravertebral vein, and 1 case slightly bulged to the paravertebral through the crack when plugging the vertebral crack. Both patients had no obvious clinical symptoms. CONCLUSION In vertebroplasty surgery, targeted sealing of high viscosity bone cement and secondary injection of low viscosity bone cement can reduce intraoperative bone cement leakage and improve the safety of operation.

We analyzed the clinical and biochemical characteristics of Japanese encephalitis(JE),based on acute meningeal and encephalitis syndrome(AMES)surveillancein Baoji from 2013 to 2021.We established the AMES program in Baoji and de-veloped surveillance according to the case definition.JE virus IgM antibody tests were conducted.Positive cases were divided in-to a probable JE and non-probable JE group according to the initial diagnosis.Clinical manifestations and biochemical character-istics of cerebrospinal fluid were compared between groups.The difference in JE incidence in the Baoji area and Shaanxiprovince before and after the AMES program was compared.Among 2 636 AMES cases reported during 2013-2021,the positive rate of JE virus IgM antibody was 5.99％,of which 86 cases(54.43％)lacked an initial JE diagnosis.The proportion of patients with fever,perturbed consciousness,neck rigidity,or meningeal irritation was significantly higher in the group with than without an initial JE diagnosis(P＜0.05).Biochemical tests indicated that the differences in cerebrospinal fluid color,white blood cell count,and chloride and glucose levels in the two groups were not statistically significant(P＞0.05).Cases of JE in Baoji from 2005 to 2012 accounted for 10.65％(134/1258)vs 16.58％(161/971).This study indicated that the AMES surveillance pro-gram increased the detection of JE and has aided in JE diagnosis.Thus,AMES surveillance should be enhanced.

Objective:To investigate the predictive value of MRI radiologic extranodal extension (rENE) for distant metastasis of prostate cancer (PCa).Methods:The data of 107 patients of initial visit with clinically diagnosed N1 PCa who underwent MRI and 68Ga-prostate specific membrane antigen (PSMA) PET/CT examinations were retrospectively analyzed at Xijing Hospital, Air Force Medical University from January 2017 to April 2022. The rENE was evaluated with MRI. According to the results of 68Ga-PSMA PET/CT, the patients were divided into the distant metastasis group (group M1, 87 cases) and the non-distant metastasis group (group M0, 20 cases). Independent sample t test, Mann-Whitney U test or χ 2 test were used to compare the differences in clinical indicators and rENE between the two groups. The multivariate logistic regression analysis was used to screen the independent risk factors affecting distant metastasis. The receiver operating characteristic (ROC) curve was used to evaluate the predictive efficacy of independent risk factors for PCa distant metastasis. Results:In group M1, 72 cases (82.8%) were rENE positive and 15 cases (17.2%) were rENE negative, and in group M0, 7 cases (35.0%) were rENE positive and 13 cases (65.0%) were rENE negative, and there was a statistically significant difference in rENE between the two groups (χ 2=19.20, P<0.001). There were significant differences in total prostate specific antigen level, International Society of Urological Pathology grade and T stage between the group M1 and the group M0 ( P<0.05). Multivariate logistic regression analysis showed that rENE (OR=6.248, 95%CI 1.807-21.600, P=0.004) was an independent risk factor for distant metastasis of PCa, and the area under the ROC curve of rENE in the diagnosis of distant metastasis of PCa was 0.739 (95%CI 0.607-0.871), the sensitivity was 82.8%, and the specificity was 65.0%. Conclusion:rENE is an independent predictor of distant metastasis of PCa, which has a high efficacy. Compared with patients with rENE negative, PCa patients with rENE positive have a higher degree of invasion and are more likely to have distant metastasis.

Abstract: Objective　To analyze the distribution and drug resistance evolution characteristics of pathogenic bacteria of bloodstream infection in nine tertiary hospitals in Yunnan Province from 2017 to 2021, so as to provide reliable basis for rational selection of antibiotics in clinic. Methods Using the drug sensitive paper method or instrument method, the bacteria identification and drug sensitivity test were carried out in nine tertiary hospitals in different regions according to the unified technical scheme. The results were judged according to the Clinical and Laboratory Standards Institute (CLSI) breakpoint standard in 2021, and use WHONET5.6 for data statistical analysis. Results A total of 12 003 strains of pathogenic bacteria were isolated from bloodstream infection samples in the past five years, including 7 442 strains of Gram-negative bacteria (62.0%) and 4562 strains of Gram-positive bacteria (38.0%), with an increasing trend in the number of isolated strains; of these, 163 strains (1.4%) were isolated from outpatients and 11 840 strains (98.6%) were isolated from inpatients. The top three gram-negative bacteria were Escherichia coli, Klebsiella pneumoniae and Acinetobacter baumannii, of which 309 strains (4.2%) were carbapenem-resistant Klebsiella pneumoniae (CR-KPN), 29 strains (0.4%) carbapenem-resistant Escherichia coli and 19 strains (0.3%) carbapenem-resistant Enterobacter cloacae, and the number of CR-KPN was on the rise year by year. The top three Gram-positive bacteria were coagulase-negative staphylococci, Staphylococcus aureus and Enterococcus faecium, of which methicillin-resistant Staphylococcus aureus (MRSA) was detected for 213 strains, accounting for 27.7%, and decreased from 40.0% in 2017 to 23.4% in 2021, showing a downward trend year by year. No vancomycin-resistant staphylococci and enterococci were found. Conclusions The detection and composition of bloodstream infection pathogenic bacteria in multicenter have not changed much in the past five years, but each hospital has its own characteristics. The number of carbapenem resistant Enterobacteriaceae increased year by year, which should be paid more attention.

Objective To investigate the relationship between the expression of glutathione peroxidase(GPX)genes and the clinical prognosis in glioma patients,and to construct and evaluate the model for predicting the prognosis of glioma. Methods The clinical information and GPX expression of 663 patients,including 153 patients of glioblastoma(GBM)and 510 patients of low-grade glioma(LGG),were obtained from The Cancer Genome Atlas(TCGA)database.The relationship between GPX expression and patient survival was analyzed.The key GPX affecting the prognosis of glioma was screened out by single- and multi-factor Cox's proportional-hazards regression models and validated by least absolute shrinkage and selection operator(Lasso)regression.Finally,we constructed the model for predicting the prognosis of glioma with the screening results and then used concordance index and calibration curve respectively to evaluate the discrimination and calibration of model. Results Compared with those in the control group,the expression levels of GPX1,GPX3,GPX4,GPX7,and GPX8 were up-regulated in glioma patients(all P<0.001).Moreover,the expression levels of other GPX except GPX3 were higher in GBM patients than in LGG patients(all P<0.001).The Kaplan-Meier curves showed that the progression-free survival of GBM with high expression of GPX1(P=0.013)and GPX4(P=0.040),as well as the overall survival,disease-specific survival,and progression-free survival of LGG with high expression of GPX1,GPX7,and GPX8,was shortened(all P<0.001).GPX7 and GPX8 were screened out as the key factors affecting the prognosis of LGG.The results were further used to construct a nomogram model,which suggested GPX7 was the most important variable.The concordance index of the model was 0.843(95%CI=0.809-0.853),and the calibration curve showed that the predicted and actual results had good consistency. Conclusion GPX7 is an independent risk factor affecting the prognosis of LGG,and the nomogram model constructed with it can be used to predict the survival rate of LGG.
