As new evidence emerges, treatment strategies toward the functional cure of chronic hepatitis B are evolving. In 2019, a panel of national hepatologists published a Consensus Statement on the functional cure of chronic hepatitis B. Currently, an international group of hepatologists has been assembled to evaluate research since the publication of the original consensus, and to collaboratively develop the updated statements. The 2.0 Consensus was aimed to update the original consensus with the latest available studies, and provide a comprehensive overview of the current relevant scientific literatures regarding functional cure of hepatitis B, with a particular focus on issues that are not yet fully clarified. These cover the definition of functional cure of hepatitis B, its mechanisms and barriers, the effective strategies and treatment roadmap to achieve this endpoint, in particular new surrogate biomarkers used to measure efficacy or to predict response, and the appropriate approach to pursuing a functional cure in special populations, the development of emerging antivirals and immunomodulators with potential for curing hepatitis B. The statements are primarily intended to offer international guidance for clinicians in their practice to enhance the functional cure rate of chronic hepatitis B.

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 explore the evaluation effect of ultrasonography and Pirani score on tarsal deformity, treatment effect and pseudo-correction of congenital clubfoot in infants and young children, and the correlation between the two methods.Methods:This is a retrospective case series study. The clinical data of 26 children (40 feet) with congenital clubfoot who were evaluated by ultrasonography in the Third Affiliated Hospital of Zhengzhou University from January 2020 to January 2023 were retrospectively collected. There were 16 males and 10 females. The age at the first ultrasound examination was ( M(IQR)) 9.0 (18.0) days (range: 1 to 46 days). All patients were treated with Ponseti method by the same physician. The Pirani scores before and after treatment and at the last examination, and the talonavicular angle, calcaneocuboid angle and tibiocalcaneal angle measured by ultrasound were collected, and the treatment and follow-up were recorded. Paired sample t test, repeated measures analysis of variance or Kruskal-Wallis test were used for data comparison, and Spearman correlation analysis was used for correlation analysis. The receiver operating characteristic curve was used to calculate the efficacy of ultrasound in evaluating different Pirani scores. Results:The number of plaster fixation in 26 children was 4.0 (1.0) times (range: 2 to 8 times). The medial talonavicular angle and posterior tibiocalcaneal angle were significantly improved after treatment and at the last follow-up compared with those before treatment, and the differences were statistically significant (all P<0.01). There was no difference in lateral calcaneocuboid angle before and after treatment and at the last follow-up ( F=1.971, P>0.05). Pseudo-correction occurred in 2 cases (2 feet) during the treatment, with an incidence of 5%. Correlation analysis showed that there was a moderate positive correlation between talonavicular angle and Pirani midfoot score ( r=0.480, P<0.01). There was no correlation between calcaneocuboid angle and Pirani midfoot score ( r=0.114, P=0.105). There was a moderate negative correlation between tibial heel angle and Pirani hindfoot score ( r=-0.566, P<0.01). The cut-off point of Pirani midfoot score of 1.5 was 38.78°, the sensitivity was 0.90, the specificity was 0.56, and the area under the curve was 0.75. The cut-off value of angle was 27.51 °, the sensitivity was 0.16, the specificity was 0.92, and the area under the curve was 0.44.The cut-off points of Pirani midfoot score of 3.0 were 45.08°and 9.96°, the sensitivity was 0.94 and 0.91, the specificity was 0.37 and 0.42, and the area under the curve was 0.59 and 0.62, respectively. The cut-off values of Pirani hindfoot score of 2.0 and 3.0 were 167.46° and 160.15°, respectively. The sensitivity was 0.75 and 0.67, the specificity was 0.81 and 0.83, and the area under the curve was 0.78 and 0.71, respectively. Conclusion:Ultrasound can complement with Pirani score, visually and dynamically observe the morphology and position changes of talonavicular joint, calcaneocuboid joint and tibiotalocalcaneal joint, monitor the recovery and pseudo-correction of tarsal bones, and better evaluate the therapeutic effect.

Objective:To investigate the characteristics and changes of bacterial infection and drug resistance in PICU at Children′s Hospital of Fudan University from 2016 to 2020.Methods:All the strains were collected at Children′s Hospital of Fudan University from January 1 st, 2016 to December 31 st, 2020.Antimicrobial susceptibility test was carried out according to a unified protocol using Kirby-Bauer method or automated systems.Results were analyzed according to CLSI 2020 breakpoints. Results:(1)Bacterial distribution: 2 551 bacteria were monitored from 2016 to 2020 in our center.The top 3 bacteria were all gram-negative bacteria.Among them, Burkholderia cepacian showed a tortuous downward trend(13.45% to 1.18%), and Klebsiella pneumoniae showed an upward trend(6.05% to 10.61%).The most common infected site was respiratory tract, although the strains in the respiratory tract decreased year by year.Baumanii was the most common bacteria in respiratory infections.Staphylococcus epidermidis was the most common bacteria from 2016 to 2017 in blood infections, but Achromobacter xylosoxidans were became the most common bacteria from 2018 to 2020.Enterococcus faecium was the most common bacteria in urinary infections.(2) Drug resistance: Baumanii had a high drug resistance rate to amikacin, gentamicin, cefepime, and cefitadine, with no obvious changes over the years, which had a gradually decreasing drus resistance rate to cefoperazone sulbactam, showing a tortuous upward trend to imipenem and meropenem.Baumanii and Pseudomonas aeruginosa had a low drug resistance to levofloxacin over the years, but with high resistance rates in 2020.Escherichia coliand and Klebsiella pneumoniae still had high resistance rates to beta-lactam antibiotics, and their resistance rates to levofloxacin were decreasing.Escherichia coli and Klebsiella pneumoniae showed decreasing resistance rates to imipenem and increased resistance rates to meropenem.The resistance rate of Enterococcus faecium to levofloxacin decreased and always showed a high susceptibility rate to polypeptide antibiotics.Neither Staphylococcus epidermidis nor Staphylococcus aureus were currently resistant to tetracycline antibiotics, and the resistance rates of aminoglycoside antibiotics, such as gentamicin, was also declining.Conclusion:The bacterial infection in PICU shows as the main characteristics of respiratory infection and gram-negative bacteria infection.Carbapenem-resistant Enterobacteriaceae bacteria, Enterococci and Staphylococcus species are becoming increasingly more resistant.

Objective:To investigate the thyroid volume of adults in Lanzhou City, and analyze its influencing factors.Methods:In June 2016, according to the principle of multi-stage stratified cluster sampling, Han residents aged 18 and above in Chengguan, Xigu and Qilihe districts of Lanzhou City who had lived there for more than 5 years were selected as research subjects, and a portable B-ultrasound machine was used for thyroid examination. Morning urine samples of the subjects were collected to test urinary iodine; fasting venous blood samples of the subjects were collected to test serum thyroid stimulating hormone (TSH), thyroid peroxidase antibody (TPOAb), anti-thyroglobulin antibody (TgAb), blood lipids [triglycerides (TG), total cholesterol (TC), low-density lipoprotein (LDL), high-density lipoprotein (HDL)] and blood uric acid (Ua) levels. At the same time, body indexes systolic blood pressure (SP), diastolic blood pressure (DP), waist circumference, height and weight were measured, and the body mass index (BMI) was calculated. Multiple linear regression was used to analyze the influencing factors of thyroid volume.Results:A total of 1 009 subjects were included, aged (43.50 ± 15.16) years, and the thyroid volume was (8.74 ± 3.39) ml. Among them, 534 males had a thyroid volume of (9.46 ± 3.43) ml; 475 females had a thyroid volume of (7.93 ± 3.15) ml, the thyroid volume of males was larger than that of females ( t = 7.36, P < 0.01). Thyroid volume was positively correlated with age, height, weight, BMI, SP, waist circumference, LDL, Ua and TgAb ( r = 0.07, 0.23, 0.33, 0.27, 0.10, 0.27, 0.10, 0.08, 0.07, P < 0.05), and it was negatively correlated with thyroid nodules, TPOAb, TSH and urinary iodine ( r = - 0.16, - 0.07, - 0.10, - 0.08, P < 0.05). After multiple linear regression analysis, TSH, TPOAb, TgAb and thyroid nodules were included in the regression equation, and the standardized B values were - 0.135, - 0.065, 0.123 and - 0.197, respectively. Conclusions:The thyroid volume of males is larger than that of females in Lanzhou City. TSH, TPOAb, TgAb and thyroid nodules are influencing factors of thyroid volume.

Objective: To analyze the urinary iodine status of urban and rural residents in some areas of Gansu Province and its related influencing factors, and to provide certain references for scientific iodine intake of urban and rural residents in Gansu Province. Methods: Subjects in Gansu Province with normal thyroid function were recruited in the investigation of thyroid diseases and iodine nutritional status, conducted a questionnaire survey and measured height, weight, waist circumference, collected 1 urine sample, and tested their urinary iodine levels. The urinary iodine levels of different groups were compared based on different gender, region, age, body weight, the waist, and salt intaking. The affecting factors of urinary iodine levels were analyzed by multiple linear regression models. Results: Totally 1 964 subjects were recruited, including 1 099 males, and 865 females. The age was (41.23 ± 14.75) years old. The median urinary iodine of the selected group was 225.60 (158.80, 311.58) μg/L. The urinary iodine level of rural residents was significantly higher than that of urban residents [μg/L: 249.80 (180.58, 336.88) vs 206.25 (148.03, 280.33), Z=-8.015, P < 0.05], and there was no significant difference between the urinary iodine levels of male and female [μg/L: 222.40 (161.60, 298.90) vs 230.60 (158.00, 326.40), P > 0.05]. The composition ratio of < 100 μg/L group in rural areas was lower than that in urban areas (5.14% vs 8.27%, χ²= 7.45, P < 0.05), and the composition ratio of ≥300 μg/L group was higher than that in urban areas (34.93% vs 21.51%, χ²= 43.87, P < 0.05). The composition ratio of ≥300 μg/L group in male was lower than that in female (24.57% vs 31.21%, χ²= 10.73, P < 0.05). The multiple linear regression analysis showed that lived in rural areas, age, moderate and severe salt intaking, student, and weight were independently correlated with urinary iodine levels (β= 0.074, -0.001, 0.059, 0.034, 0.096, -0.003, P < 0.05). And the urinary iodine levels were decreased with age and weight increased (P < 0.05). Conclusions At present, the iodine nutrition level of urban and rural residents in some areas of Gansu Province is generally over the adequate level. The urinary iodine level of rural residents is higher than that of urban residents. In the future, we should pay attention to the impact of different living areas, salt intaking and body weight on urinary iodine levels to prevent thyroid diseases.

Objective To investigate the clinical effect of selective bronchial artery infusion chemotherapy for central squamous cell carcinoma of the lung.Methods 93 cases of central lung squamous cell carcinoma patients who were treated in our hospital from February 2015 to February 2017 were enrolled in the study.They were divided into the observation group (n =45) and the control group (n =48) according to the patients'final treatment.The observation group was treated with bronchial artery perfusion chemotherapy,and the control group was treated with systemic venous chemotherapy.The short-term effect and the improvement of lung function in the two groups were observed,and the prognosis of the patients was followed up.Results The short-term effect of the observation group was better than that of the control group (P ＜0.05),and the total effective rate of the observation group was 95.56％;The forced vital capacity (FVC)and forced expiratory volume in the first second (FEV,) of the observation group were (75.39 ± 6.88)％and (78.19 ± 7.79)％,respectively,which were significantly higher than those in the control group (P ＜0.05).The reoperation ratio of the observation group was 44.44％ after chemotherapy,which was significantly higher than that of the control group,with statistically significant difference (P ＜ 0.05).The median total survival time of the observation group was 17 months,which was significantly higher than that of the control group,with statistically significant difference (P ＜ 0.05).The incidence of adverse reaction in the observation group was 6.67％,which was significantly lower than that in the control group,with statistically significant difference (P ＜ 0.05).Conclusions Selective bronchial artery infusion chemotherapy for central lung cancer is effective and worthy of clinical application.
