Objective To analyze the status of the bacteria in the operative area of transnasal skull base surgery and its correlation with postoperative intracranial infection.Methods The procedure of transnasal skull base surgery was divided into three stages:nasal passage preparation(stage 1),tumor resection(stage 2),and skull base reconstruction(stage 3).Bacterial sampling was taken from the mucosa of the anterior wall of sphenoid sinus or clival recess of sellar floor at the beginning of each stage;and the positive rate of bacterial culture in different stages of operation and its correlation with postoperative intracranial infection were analyzed.Results A total of 105 patients were enrolled in this study,and 315 samples were taken.The average time point of sampling in the three stages was 20.3,45.1 and 131.3 min after the beginning of operation,respectively.The positive results were 9 cases(2.9％)in the stage 1,8 cases(2.5％)in the stage 2,and 23 cases(7.3％)in the stage 3,which were 24 cases of Staphylococcus epidermidis,7 cases of Staphylococcus aureus,3 cases of hemolytic streptococcus,2 cases of Klebsiella pneumonia,and 4 cases of Escherichia coli.There was no significant difference in the positive cases between stage 1 and stage 2(P=0.955),but there were significant differences between stage 1 or 2 and stage 3(P=0.013;P=0.007).There were 36(11.4％)patients with at least one positive result in the three stages,17(16.2％)with cerebrospinal fluid leakage,and 12(11.4％)with intracranial infection.The risk of intracranial infection was 3.1 times higher in patients with positive bacterial culture than patients with negative bacterial culture(OR=3.1,95％CI:0.9-10.6),which was not statistically significant;patients with CSF leakage were 61.4 times higher than those without CSF leakage(OR=61.4,95％CI:11.2-337.1),which was statistically significant(P＜0.001).The consistency rate of bacteria in nasal cavity and postoperative cerebrospinal fluid culture was 57.1％.Conclusion The positive rate of bacterial culture in the operative area of transnasal skull base surgery increases significantly with the extension of operation time,which is a potential risk index of postoperative intracranial infection.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

AIM: To analyze the correlation of changes in non-contact intraocular pressure(IOPNCT)and the surgical parameters after femtosecond laser small incision lenticule extraction(SMILE)for high myopia.MOTHODS:A retrospective analysis, the clinical data of 98 patients(196 eyes)with high myopia were operated SMILE in the optometric center of Gansu Provincial Hospital from January 2018 to July 2019 were analyzed. The change of IOPNCT before and after operation was observed, and recorded the optical zone(OZ), lenticule thickness(LT), cap thickness(CT)and residual stromal thickness(RST)and the correlation with the change value of IOPNCT(△IOPNCT, △IOPNCT=IOPpreoperative-IOP postoperative at 6mo).RESULTS:After operation at 1d, 1wk, 1,3 and 6mo, the group of patients with IOPNCT(10.84±2.14,11.00±2.19,10.65±2.43,10.45±2.04,10.61±1.39mmHg)and the preoperative(16.79±1.65mmHg)comparison have a difference(P<0.001).The optical zone and lenticule thickness were positively correlated with △IOPNCT respectively(r=0.1537, 0.8161, all P<0.05). The cap thickness and residual stromal thickness were negatively correlated with △IOPNCT respectively(r=-0.8362, -0.3351, all P<0.0001). Introduce the above related factors into a multiple linear regression analysis model. The regression coefficients of variables are statistical significane. The regression equation was Y=16.189+0.227X1+0.032X2-0.083X3-0.007X4(Y=△IOPNCT, X1=OZ, X2=LT, X3=CT, X4=RST). The equation was statistically significant(F=195.704, P<0.001), and the regression model coefficient of determination R2=0.901.CONCLUSION:The intraocular pressure changes after SMILE with high myopic were correlated with optical zone, lenticule thickness, cap thickness and residual stromal thickness. The regression equation would provide reference to evaluation the real intraocular pressure after SMILE in clinic.

Golgi protein 73 (GP73) is a transmembrane protein on the Golgi apparatus and can be cut and released into the blood. In recent years, an increasing number of clinical studies have shown that the elevated serum GP73 level is closely related to liver diseases. And thus GP73 is expected to be used as a new serum marker for assessing progress of chronic liver diseases. Herein, the clinical application of serum GP73 in chronic hepatitis, liver fibrosis, liver cirrhosis and hepatocellular carcinoma with different etiologies was reviewed based on available literatures; and a research outlook in this field is made.

BACKGROUND: It has been a global trend that increasing complications related to pelvic floor surgeries have been reported over time. The current study aimed to outline the development of Chinese pelvic floor surgeries related to pelvic organ prolapse (POP) over the past 14 years and investigate the potential influence of enhanced monitoring conducted by the Chinese Association of Urogynecology since 2011. METHODS: A total of 44,594 women with POP who underwent pelvic floor surgeries between October 1, 2004 and September 30, 2018 were included from 22 tertiary academic medical centers. The data were reported voluntarily and obtained from a database. We compared the proportion of each procedure in the 7 years before and 7 years after September 30, 2011. The data were analyzed by performing Z test (one-sided). RESULTS: The number of different procedures during October 1, 2011-September 30, 2018 was more than twice that during October 1, 2004-September 30, 2011. Regarding pelvic floor surgeries related to POP, the rate of synthetic mesh procedures increased from 38.1% (5298/13,906) during October 1, 2004-September 30, 2011 to 46.0% (14,107/30,688) during October 1, 2011-September 30, 2018, whereas the rate of non-mesh procedures decreased from 61.9% (8608/13,906) to 54.0% (16,581/30,688) (Z = 15.53, P < 0.001). Regarding synthetic mesh surgeries related to POP, the rates of transvaginal placement of surgical mesh (TVM) procedures decreased from 94.1% (4983/5298) to 82.2% (11,603/14,107) (Z = 20.79, P < 0.001), but the rate of laparoscopic sacrocolpopexy (LSC) procedures increased from 5.9% (315/5298) to 17.8% (2504/14,107). CONCLUSIONS: The rate of synthetic mesh procedures increased while that of non-mesh procedures decreased significantly. The rate of TVM procedures decreased while the rate of LSC procedures increased significantly. TRIAL REGISTRATION NUMBER NCT03620565, https://register.clinicaltrials.gov.
