Acute obstructive suppurative cholangitis (AOSC) is one of the most serious acute abdomen.The incidence of abdominal infection is significantly improved when patients were complicated with AOSC and diabetes mellitus,and then bile leakage,intestinal fistula and even death were induced by abdominal infection.The management of abdominal infection is very important for the prognosis of patients.One patient with AOSC and diabetes mellitus was admitted to the No.425 Hospital of PLA from May to July in 2013.Recurrent abdominal infection and abscess occurred after the operation due to his family members' refusal of surgery at early period and lax control of blood glucose before and after surgery,and then bile leakage and intestinal fistula were induced.The patient underwent operation for 3 times,and was cured after receiving fasting,gastrointestinal decompression,parental nutrition,somatostatin administration and antibiotic treatment.

Aim To investigate the effect of intrauterine injection of rat fetal hepatocytes on homograft rejection reaction. Methods The skin graft from a male LOU/CN rat was transplanted to a female recipient CHN rat of 7 to 9 weeks after parturition, and then survival time of the graft was observed. Simultaneously, homograft rejection reaction was examined by mixture lymphocyte culture. Results As compared with control group, survival time of transplanted skin graft was obviously prolonged. Mixure lymphocyte culture demonstrated that homograft rejection reaction was inhibited markedly. Conclusion Intrauterine injection of rat fetal hepatocytes wuld obviously inhibite homograft rejection reaction, thus prolonging survival time of the graft.

Orbital tumors not only damage the appearance of patients, but also damage the visual function, even endanger the life of patients.Orbital tumors can be divided into epidermal ectoderm, neuroectoderm, mesoderm, lymphopoietic system and metastatic tumors according to their origin.Due to the complex structure of orbital tissue, abundant nerve vessels and close connection with visual organs, it is more difficult and risky to treat orbital tumors than other regional tumors.Classic treatments for tumors include surgical resection, chemotherapy, and radiotherapy.Surgery is the main treatment for most orbital tumors.Due to the improvement of technology and equipment, it has been developed in the direction of minimally invasive surgery.For advanced tumors or lymphoid hematopoietic system tumors with extensive invasion, chemotherapy is the main treatment.Due to the improvement of drug delivery methods and protocols, it is developing towards high efficiency and less side effects.Radiotherapy is mostly used for refractory tumors that are difficult to be completely removed by surgery and easy to relapse.Due to the continuous improvement of radiotherapy technology, safe and accurate treatment has been achieved.In addition to the classical treatment methods, targeted treatment of carcinogenic sites at the molecular level has become a hot topic in the treatment of orbital tumors.This paper reviews the current development of orbital tumors in surgical resection, chemotherapy, radiotherapy and targeted therapy.

Objective:To systematically analyze the efficacy of nasal endoscopic transsphenoidal decompression and glucocorticoid pulse therapy for traumatic optic neuropathy (TON).Methods:PubMed, Web of Science, Cochrane Library, ClinicalTrial.gov, CNKI, Wanfang, China Biomedical and other databases were searched to retrieve clinical studies on endoscopic surgery and hormone therapy for TON since their establishment to November 1, 2020.Two researchers screened the literature and evaluated the quality of the included literatures.The improvement of visual acuity before and after treatment was taken as an effective indicator.RevMan 5.3 statistical software was used for meta-analysis.The sensitivity of the results was analyzed atfer literature exclusion.The publication bias of each study was double checked by funnel plot and Begg test.Results:Eight studies were included, including 7 cohort studies and 1 randomized controlled trial.There was no significant difference between the endoscopic decompression group and glucocorticoid group in the efficiency of visual acuity improvement in the treatment of TON [odds ratio ( OR)=1.65, 95% confidence interval ( CI)∶0.75-3.66, P=0.22], neither in TON patients with residual vision before surgery ( OR=2.17, 95% CI: 0.94-4.98, P=0.07). For nasal endoscopic decompression surgery, early surgery (disease course<7 days) was more effective than late surgery (disease course>7 days) ( OR=4.73, 95% CI: 2.55-8.78, P<0.01). Sensitivity analysis suggested that the results of this literature analysis were not robust.The Begg test showed that there was no literature publication bias. Conclusions:There is no significant difference between nasal endoscopic surgery and glucocorticoid therapy in the treatment of TON.Early endoscopic surgery may help improve visual acuity in patients with residual vision.

The finite element method(FEM)is a widely employed mathematical technique in mechanical research that divides an object into discrete and interacting finite elements. Medically, finite element analysis(FEA)enables the simulation of biomechanical experiments that are challenging to conduct. Orbital surgery poses significant challenges to ophthalmologists due to its inherent difficulty and steep learning curve. FEM enables the simulation and analysis of the mechanical properties of orbital tissue, offering a novel approach for diagnosing and treating orbital-related diseases. With technological advancements, FEM has significantly matured in the diagnosis and treatment of orbital diseases, becoming a popular area of research in orbital biomechanics. This paper reviewed the latest advancements in orbital FEM, encompassing the development of orbital FEA models, simulation of orbital structure, and its application in orbital-related diseases. Additionally, the limitations of FEM and future research directions are also discussed. As a digital tool for auxiliary diagnosis and treatment, orbital FEA will progressively unlock its potential for diagnosing and treating orbital diseases alongside technological advancements.
