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 predictive value of the prognostic nutritional index (PNI) in concurrently infected patients with acute-on-chronic liver failure (ACLF).Methods:220 cases with ACLF diagnosed and treated at the First Affiliated Hospital of Xi'an Jiaotong University from January 2011 to December 2016 were selected. Patients were divided into an infection and non-infection group according to whether they had co-infections during the course of the disease. Clinical data differences were compared between the two groups of patients. Binary logistic regression analysis was used to screen out influencing factors related to co-infection. The receiver operating characteristic curve was used to evaluate the predictive value of PNI for ACLF co-infection. The measurement data between groups were compared using the independent sample t-test and the Mann-Whitney U rank sum test. The enumeration data were analyzed using the Fisher exact probability test or the Pearson χ2 test. The Pearson method was performed for correlation analysis. The independent risk factors for liver failure associated with co-infection were analyzed by multivariate logistic analysis. Results:There were statistically significant differences in ascites, hepatorenal syndrome, PNI score, and albumin between the infection and the non-infection group ( P ?

Objective:To explore the causal relationship between body mass index (BMI) and hypothyroidism using the two-sample Mendelian randomization model.Methods:A large-scale anthropometric genome-wide association study published in the GIANT database was used to select single nucleotide polymorphisms (SNPs) which were statistically significantly associated with BMI as an instrumental variable ( P<5×10 -8, linkage disequilibrium r 2<0.1). The causal relationship between BMI and hypothyroidism was determined by the inverse variance weighted (IVW), weighted median method and the MR-Egger method, respectively. A heterogeneity test, gene pleiotropy test, and sensitivity analysis were performed to evaluate the stability and reliability of the results. Results:A total of 89 SNPs related to BMI were screened out as instrumental variables. IVW analysis suggested that for every standard deviation increase in BMI, the risk of hypothyroidism increased by 0.9% (odd ratio ( OR)=1.009, 95% confidence interval ( CI): 1.006-1.012, P<0.001). Similar results were obtained with the weighted median method ( OR=1.007, 95% CI: 1.002-1.011, P=0.003) and the MR-Egger method ( OR=1.008, 95% CI: 1.001-1.015, P=0.006). The MR-Egger analysis showed that genetic pleiotropy did not bias the results (intercept=0.000 1, P=0.776), the one-by-one exclusion method did not show that a single instrumental variable SNP had a significant impact on the results, and the difference was not statistically significant ( P>0.05). Conclusion:Mendelian randomized analysis showed a positive causal relationship between BMI and hypothyroidism.

Objective:To analyze the diagnosis and treatment process of a kala-azar case with prominent renal damage treated with liposomal amphotericin B (L-AmB), and to provide theoretical basis for clinical diagnosis and treatment.Methods:A retrospective analysis method was used to analyze the clinical data, diagnosis and treatment process and laboratory test results of a case of kala-azar with prominent renal damage who presented to the Department of Infectious Diseases, The First Affiliated Hospital of Xi'an Jiaotong University on June 30, 2020.Results:A 56-year-old female patient presented with fever (the highest body temperature was 38.2 ℃) and chills. The results of clinical laboratory tests showed that hemoglobin(55 g/L), red blood cell (2.68 × 10 12/L), white blood cell (1.06 × 10 9/L) and platelet count (8.00 × 10 9/L) were decreased, renal function showed abnormal blood urea nitrogen and creatinine, spleen enlargement, etc., and the diagnosis of kala-azar combined with kidney insufficiency was confirmed by blood and bone marrow Leishmania spp. examination. With the assistance of continuous renal replacement therapy (CRRT), after a small dose of L-AmB was initially and slowly increased and maintained at a low dose, the patient's body temperature was normal, the blood routine showed that the three-lineage cells gradually increased, and the renal function showed blood urea nitrogen and creatinine decreased gradually the spleen was retracted; no recurrence was found at follow-up after 6 months, and renal function returned to normal. Conclusions:L-AmB is safe and effective in the treatment of kala-azar with renal damage as the prominent manifestation. The patient is not only cured by etiology, but is also recovered renal function.

Objective:To investigate the efficacy and safety of individualized rituximab rescue therapy for active lupus nephritis with acute kidney injury (AKI).Methods:The clinical data of lupus nephritis patients with AKI treated with rituximab at the Kidney Disease Center of the First Affiliated Hospital of Zhejiang University School of Medicine from April 2017 to June 2020 were collected, and the renal remission rate and adverse events after rituximab treatment were analyzed retrospectively. The Kaplan-Meier method was used to calculate the cumulative incidence of patients' remission.Results:There were 13 patients enrolled, including 8 females, and aged (35.23±15.92) years old. The urinary protein/creatinine ratio was (5.22±1.57) g/g before rituximab treatment. Four patients were on dialysis at admission, and 9 patients without dialysis had serum creatinine of (223.22±85.73) μmol/L. Eight patients were confirmed as proliferative lupus nephritis by renal biopsies, including 7 cases with crescent formation and 1 case with thrombotic microangiopathy (TMA), and the other 5 cases without renal biopsies were clinically diagnosed as TMA. The dose of rituximab was (815±516) mg (200-2 100 mg), and all the patients reached the state of peripheral blood B cells clearance (CD19 + B cell count was<5/μl). After the first treatment of rituximab, the median time to B-cell clearance was 21(15, 35) days, and 8 patients reached B-cell depletion (CD19 + B cell count was 0). The remission rate was 12/13 (two cases reached complete remission, and 10 cases reached partial remission). Three cases stopped dialysis, and 1 case (with glomerulosclerosis of 52.94%) entered maintaining dialysis. The relapse times in the maintenance remission period of 7 patients with refractory lupus nephritis declined significantly from (1.57±0.53) times in a median history of 60(20, 109) months to (0.43±0.79) times in a median history of 18(10, 23) months after the use of rituximab ( P=0.015). After using rituximab, the incidence of infection was 7/13. The median time from the use of rituximab to infection was 26(4, 44) days. Pulmonary infection (5/13) was the most common type and all infected patients recovered after anti-infection treatment. Conclusions:Rituximab can be used in the treatment of active lupus nephritis with AKI, especially in patients with crescent formation and TMA, but the infection should be paid close attention to and prevented.

Objective To explore the effect of cisapride combined with polyethylene glycol electrolytic solution on preoperative bowel preparation for patients receiving colorectal cancer operation. Methods One hundred and fifty-two patients received colorectal cancer opera-tion in our hospital from October 2010 to October 2014 were selected. Those who were treated with cisapride combined with polyethylene gly-col electrolytic solution for bowel preparation before operation were assigned to oberservation group(n=83),those who were treated with poly-ethylene glycol electrolytic solution for bowel preparation before operation were assigned to control group(n=69). The side effect after medi-cation, electrolyte concentration and incidence of incision infection between groups after operation were collected and compared. Results The incidence of nausea and vomiting was 7. 23% in observation group,which was significantly lower than 18. 84% in control group (χ2 =4. 64,P=0. 03). The difference of Na+,K+ and Cl- concentration between groups were not significant (t=1. 83,P=0. 07;t=0. 42,P=0. 68;t=1. 86,P=0. 07). The body temperature,leukocyte count and incidence of incision infection after operation in observation group were significantly lower than those in control group (t=2. 68,P<0. 01;t=3. 29,P<0. 01;χ2 =4. 90,P=0. 03). Conclusion Cisapride com-bined with polyethylene glycol electrolytic solution before operation can significantly decrease the incidence of gastrointestinal side effect after medicaiton and incision infection after operation and it is beneficial to recovery for patients with colorectal cancer operation.

Background and purpose: Primary signet ring cell carcinoma(SRCC) of the bladder is rarely diagnosed in the clinic. Few cases have been reported in the literature, so there was lack of understanding of the primary bladder SRCC in terms of diagnosis and treatment. Our study was to investigate the clinical features and treatment strategy for primary SRCC of the bladder and review the status of the disease along with the literature. Methods: 3 cases of primary bladder SRCC were studied, including clinical features, treatment, follow-up and their prognosis.The literature was reviewed. Results: All cases received ultrasound, computerized tomography, cystoscopy, biopsy and other related lab tests for diagnosis and differential diagnosis. Laparoscopic radical cystectomy and orthotopic ileal neobladders were performed in 2 cases, while the other case received laparoscopic radical cystectomy and ileal conduit diversion, Chemotherapy (cisplatin and 5-fluorouracil) was delivered in one case after surgery. One patient died at 6 months postoperatively because of multiple metastasis. The other 2 cases have been followed-up only for 8 and 12 months postoperatively, and no recurrence or metastasis have been observed. Conclusion: Primary SRCC of the bladder lacks distinctive clinical and imaging manifestations. The tumor grows very invasively. Radical cystcctomy is one of the optimal approaches for treatment of SRCC of bladder.

Background and purpose: The prognostic factors on survival for the patients with prostate carcinoma are still underdeterrnined. This study was to analyze the survival of three common treatment methods for prostate carcinoma and the prognostic factors on survival. Methods: 494 male patients who were diagnosed as prostate cancer were enrolled into the retrospective study. All of the data like age, stage, grade, PSA level, ALP, Hb and treatments were collected. Overall survival and disease specific survival rates for patients were analyzed by Kaplan-Meier method. Prognostic factors on disease specific survival were also analyzed by Log-rank test and Cox proportional hazards model. Results: Disease specific survival rates at 1, 3 and 5 year were 96.0%, 89.0% and 80.0% for all 494 patients, respectively. Disease specific survival rate at 3-year was 92.4% for brachytherapy, 100.0% for radical prostatectomy and 80.6% for hormonal therapy (P=0.008). Multivariate analysis by Cox model showed that stage, PSA level and age significantly impacted on disease specific survival. Conclusion: Brachytherapy and radical prostatectomy provides longer survival time than hormonal therapy for patients with prostate cancer. Clinical stage and PSA level and age of prostate cancer are independent factors impacting on survival significantly.
