ABSTRACT
Primary biliary cholangitis (PBC) is an inflammatory and cholestatic liver disease caused by autoimmune response targeting the small- and medium-sized intrahepatic bile ducts. The most specific manifestations of this diseases in clinical practice were positive anti-mitochondrial antibody and selective destruction of small- and medium-sized bile ducts based on liver histology. Since it is difficult to obtain the clinical samples of early-stage PBC, the construction and optimization of mouse models is an important method to investigate the pathogenesis of PBC. An understanding of the modeling principles of PBC animal models and disease features in serology, histology, and cytology not only helps to improve the awareness of PBC, but also helps to design scientific and rational research protocols.

ABSTRACT
Objective To study the auditory perception and speech ability outcomes after cochlear implantation in prelingually deaf children with extremely severe neurosensory hearing loss and comorbid leukoencephalopathy.Methods Our study included 14 prelingually deaf children with leukoencephalopathy (confirmed by preoperative MRI scanning) who were treated with cochlear implantation in the Department of Otorhinolaryngology Head and Neck Surgery of Hainan Provincial People''s Hospital, including 8 males and 6 females of 1~6 yr with a mean age of 3.8 yr.Sixteen synchronous prelingually deaf children without central nervous system (CNS) diseases were also included as the control group, including 11 males and 5 females of 1~6 yr with a mean age of 4.4 yr.All the patients underwent pre-surgical assessments of audiology, radiology, speech ability and intelligence before cochlear implantation via transmastoid facial nerve recess approach was done, after which rehabilitation was provided at the Hainan Rehabilitation Center for Deaf Children.Categories of auditory performance (CAP) and speech intelligibility rate (SIR) were employed as the assessment criteria for the outcome of surgery, the scores of which at different timepoints after surgery were statistically compared through paired t-test between the two groups.Results All the patients gained post-surgical hearing and speech abilities to different degrees, whereas CAP and SIR scores both chronologically improved in the both groups.No statistical difference was revealed either in CAP or in SIR scores between the two groups at 6, 12 and 24 months after surgery (P>0.05).Conclusion Children with extremely severe neurosensory hearing loss can be reated with cochlear implantation even if they have comorbid leukoencephalopathy.The effects of auditory and speech rehabilitation for the same age patients with leukoencephalopathy are similar to those without leukoencephalopathy in 2 years after surgery.
ABSTRACT
Primary biliary cholangitis (PBC) is a chronic cholestatic autoimmune disease caused by the attack of the liver by the immune system and is commonly seen in middle-aged women.The pathological features of this disease include the infiltration of a large number of innate immune cells (NK cells,NK T cells,and monocytes,etc.) and adaptive immune cells (T lymphocytes and B lymphocytes) at the portal area and injury of small intrahepatic bile ducts.In addition,PBC patients have high serum levels of anti-mitochondrial antibodies and inflammatory cytokines such as interferon-γ,tumor necrosis factor-α,interleukin-6,and interleukin-12.Although current studies have shown that autoreactive T cells are the major effector cells for PBC,NK cells,NK T cells,monocytes,and B cells around the portal vein also directly or indirectly participate in the development and progression of PBC.This article systematically summarizes the role of innate immune cells,adaptive immune cells,and related chemokines in the pathogenesis of PBC,in order to provide a theoretical basis for a deep understanding of the immunological pathogenesis of PBC.
ABSTRACT
Objective To evaluate the accuracy of ultrasound-measured inferior vena cava (IVC) diameter in assessment of the preoperative blood volume in elderly patients.Methods Sixty patients,aged 60-75 yr,with body mass index 20-25 kg/m2,of ASA physical status Ⅰ-Ⅲ,scheduled for elective transurethral resection of prostate,were randomly divided into 3 groups (n =20 each):control group (group C),lactated Ringer's solution group (group RL),and hydroxyethyl starch group (group H).Lactated Ringer's solution 8 ml/kg was infused intravenously in group RL.Hydroxyethyl starch 130/0.4 8 ml/kg was infused intravenously in group H.SpO2,mean arterial pressure (MAP),HR and central venous pressure (CVP) were monitored before and after fluid therapy.The IVC diameters,both during expiration (IVCe) and inspiration (IVCi),were measured using ultrasound.IVC collapsibility index (IVC-CI) was calculated.Results The IVCeand IVCi were significantly increased,and IVC-CI was decreased after fluid therapy as compared with those before fluid therapy in RL and H groups.Compared with group C,the IVCe and IVCi were significantly increased,and IVC-CI was decreased after fluid therapy in RL and H groups.IVCe and IVCi were positively correlatedwith CVP (r=0.746 and 0.697,respectively).IVC-CI was negatively correlated with CVP (r =-0.547).Conclusion Ultrasoundmeasured IVC diameter provides better accuracy in assessing the preoperative blood volume in elderly patients.

ABSTRACT
ObjectiveTo investigate the effects of sevoflurane on short-term memory impairment and the relative synaptic mechanism.MethodsAt 12 h,24 h and 72 h after the mice were exposed to 1.5％ sevoflurane for 1h,the spontaneous alternation and locomotor activity was assessed by Y maze,the short term potentiation (STP) were measured with extracellular recording technique in hippocampal slices.ResultsAt 12h after administration with sevoflurane in vivo,the spontaneous alternation ( (54.7 ± 1.7) ％,P＜0.01 ) and locomotor activity (16.4 ± 1.3,P ＜ 0.01 ) decreased significantly compared with that of control group,and the population spike amplitude after induction of STP ( ( 122.3 ± 13.9) ％,P ＜ 0.05 ) decreased significantly in hippocampal slices,but there was no different at 24h and 72h.After administration with sevoflurane in vitro,the basic ( ( 83.5 ± 8.9) ％,P ＜ 0.01 ) or titanic ( ( 116.5 ± 14.9) ％,P ＜ 0.01 ) population spike amplitude decreased significantly in hippocampal slices,but the amplitude could recovery after wash-out.ConclusionSevoflurane can impair the shortterm memory by suppressing synaptic transmission in the near future but not the long future.

ABSTRACT
OBJECTIVE To improve the knowledge on the early diagnosis and treatment of the isolated fungus ball sphenoid sinusitis.METHODS A retrospe ctive study was made on10cases of isolated fungus ball sphenoid sinusitis to discuss the clinical manifestation,radiographic features and treatment with endoscopic sinus surgery.RESULTS The common symptoms in10cases were headache and/or bloody nasal discharge.Radiographic features of the disease were a soft tissue image occupying the sphenoid sinus with bones wall thickening.A soft tissue image with calcification in the sphenoid sinus was the feature of CT image.All the patients were treated by nasal endoscopic sinus surgery and cured after followed up for3to18.CONCLUSION Isolated fungus ball sphenoid sinusitis was difficult to diagnose in early stage because of its non-specif ic symptoms.The nasal endoscopy and CT scan make the early diagnosis possible.The diagnosis can be def initely confi rmed by pathological studies.Treatment with endoscopic sinus surgery is an effective method for fungus ball sphenoid sinusitis.
