Objective To evaluate the relationship between intraocular pressure (IOP) and anterior chamber angle in patients with different types of acute angle-closure glaucoma after phacoemulsification and intraocular lens implantation. Design Retrospective case series. Participants 173 cases of acute angle-closure glaucoma coexisting cataract (173 eyes) in Mingren Eye Hospital from January, 2005 to June, 2007. Methods All patients with acute angle-closure glaucoma underwent phacoemulsification and intraocular lens implantation, and were examined with high-frequency ultrasound biomicroscopy (UBM). Anterior chamber depth (ACD), intraocular pressure (IOP) and anterior chamber angle (ACA) were measured. Follow-up was 1-48 weeks after surgery. Main Outcome Measures Intraocular pressure, phacoemulsification complications, re-open rate of anterior chamber angle. Results At 8th week after surgery, the rate of IOP control in pupillary block group, non-pupillary blocking group, and multimechanism group was 88.9%, 52.0%, 83.4%, respectively and there was a statistically significant between these groups (?2=7.13, P=0.022). At 48th week, the rate of IOP control was 54.2%, 33.3%, 35.8%, respectively(?2=12.56, P=0.003). Fifty patients were follow up with UBM, and 66.7% in pupillary block group, 33.3% in non-pupillary blocking group and 33.3% in multimechanism group in 48 weeks postoperatively showed evidence of the widened anterior chamber angle. No specific postoperative complications were found in this study compared with those with phacoemulsification without glaucoma. Conclusions The use of phacoemulsification and intraocular lens implantation for acute angle-closure glaucoma coexsiting cataract can get best IOP-controlled rates in pupillary block group. It is related to the degree of widened anterior chamber angle.

Objective:To analyze the clinical and gene mutation characteristics of congenital disorder of glycosylation (CDG) caused by compound heterozygous mutation of the COG6 gene ( COG6-CDG). Methods:This study retrospectively analyzed the clinical data and genetic test results of a patient with COG6-CDG in Bayi Children's Hospital, the Seventh Affiliated Medical Center of Chinese PLA General Hospital, in August 2019. Literature was retrieved with keywords including COG6, COG6-CDG, congenital disorders of glycosylation typeⅡL and congenital disorders of glycosylationⅡL in China National Knowledge Infrastructure, Wanfang Database, VIP Database, PubMed, and Web of Science Database from the establishment to July 2020, to summarize the clinical and genetic characteristics of COG6-CDG. Results:(1) Case report: The 59-day-old baby boy, with a gestational age of 27 +5 weeks and birth weight of 1 180 g, presented with multi-system involvement on admission, including unidentified progressive hepatosplenomegaly with jaundice and ascites, persistent thrombocytopenia, microcephaly, hypotonia, hypohidrosis, hyperkeratosis, and recurrent hyperthermia, infection, and hypoglycemia, as well as dysfunctions of the heart, gastrointestinal tract, lungs, kidneys, ocular fundus, and the coagulation system. Despite given ventilator-assisted ventilation, anti-infection therapy, abdominal puncture and drainage, and blood transfusion, the patient still had an aggravated condition and eventually died of multiple organ failures 192 d after birth. Genetic analysis showed that the nuclear family carried compound heterozygous mutations in the COG6 gene (NM_020751.2), including missense mutations of c.662C>T(p.T221M) in exon 7 and c.443T>C(p.I148T) in exon 5, which were both novel mutations and originated from the mother and father, respectively. (2) Literature review: Eight related papers were retrieved, including 20 cases. The main manifestations were various degrees of nervous system abnormalities and growth retardation, complicated by abnormalities of the liver, heart, gastrointestinal tract, blood, immunity, teeth, and bones. All the reported cases suffered from mental and growth retardation, and nine deaths were reported. A total of 11 COG6 gene mutations were identified, and most of them were c.1167-24A>G splicing mutations in a deep intron (seven cases), followed by c.1646G>T (four cases) and c.511C>T (three cases). Conclusions:COG6-CDG commonly manifests as multi-system and multi-organ dysfunctions with poor prognosis. Gene detection is conducive to the accurate diagnosis of COG6-CDG. Our case carries compound heterozygous mutations of c.662C>T(p.T221M) and c.443T>C(p.I148T), which are unreported novel mutations.

Objective　To analyze the clinicopathologic characteristics and treatment of primary and secondary bladder mucosa lymphoma.　Methods　From June 1996 to September 2011,8 cases of bladder mucosa lymphoma patients including primary bladder mucosa lymphoma patients (2 males and 3 females)and secondary bladder mucosa lymphoma patients ( 1 male and 2 females) were treated in our institute.The patient's mean age was 68 years (ranged from 57 to 78 years),and the other 3 secondary bladder mucosa lymphoma patient's mean age was 61 years (ranged from 41 to 81 years).7 of 8 patients accepted transurethral resection of bladder tumor combined with CHOP chemotherapy and radiotherapy,and 1 patient abandoned treatment.CHOP chemotherapy and radiotherapy were performed at 2 weeks post-operatively.Secondary bladder mucosa lymphoma patients accepted 3-dimensional conformal 6000 cGy radiotherapy.Urinary CT examination showed that there were round or oval irregular tumors in the wall of urinary bladder,whose diameters were 1 to 4 cm.Tumor edges were glossy and tumor density were uniform.In addition,the bladder wall with tumor was uneven.In contrasted CT,the tumors appeared obviously enhanced.7 cases had cauliflower-like tumors found by cystoscope,and there were necrosis-calcification area in the center of tumors.1case appeared multiple tumors,which consisted of one big tumor and three smaller ones.　Results　There were 5 cases of primary bladder mucosa lymphoma, including 3 bladder mucosa associated lymphoma (MAL) cases and 2 diffuse large B cell lymphoma cases.There were 3 secondary bladder mucosa lymphoma cases including 2 diffuse large B cell lymphoma cases and 1 generalized follicular cystic central lymphoma case,which belongs to the tuberous sclerosis Hodgkin lymphoma.Immunohistochemical analysis showed that CD20,CD21,CD43 staining were positive in low grade MAL (3 cases).However,CD3,CD20,CD31 staining were positivein high grade MAL (5 cases). All patients were followed up 3 to 44 months.3 cases of secondary malignant lymphoma patients died after diagnosed after 3 to 13 months.5 cases of primary malignant lymphoma patients were all survived. 1 case recurred 14 months after surgery and accepted TURBT and CHOP chemotherapy again.Pathologic diagnosis showed the transformation from peripheral zone of bladder mucosa associated lymphoma to diffuse large B cell lymphoma.The patient was free of recurrence.　Conclusions　MAL and diffuse large B cell lymphoma are the most common type of bladder mucosa lymphoma.Primary and secondary diffuse large B cell lymphoma have similarities in histological analysis,but the former prognosis is better than the latter's. Transurethral resection of bladder tumor combined with chemotherapy and radiotherapy can prevent the relapse of MAL in short term and long term with good tolerance,and can be used as ideal treatment of MALT.

Objective To compare imaging quality and radiation dose on full-field digital mammography (FFDM) system and dual-sided reading CR mammography (DSCRM) system.Methods The TRM of ALVIM statistics phantom was exposed by FFDM system and (DSCRM) with the same radiation dose.The exposure parameters and the entrance surface dose (ESD) were recorded.Then,the phantom was exposed by DSCRM system with different mAs and same kV,and the ESD was recorded.The images obtained above were read by three radiologists on the monitor of diagnosis work station with the same window width and window level.The evaluation of the images were given using a five-level confidence scale.ROC curves were drawn and probability Pdet were calculated.Results The ROC analysis of microcalcifications and masses showed A(z) values of 0.730-0.925 and 0.670-0.945 for FFDM,and 0.632-0.815 and 0.575-0.785 for DSCRM when the radiation dose is 1.36 mGy.The radiation dose with DR system could be reduced compared with dual-sided reading CR system at the same probabilities Pdet,the ESD reduced from 1.63 mGy to 1.36 mGy by 19.8％,the AGD reduced from 0.65 mGy to 0.56 mGy by 16.0％.Conclusions The observable details with FFDM system were proved to be superior to DSCRM system at the same radiation dose.With the similar image quality,the radiation dose of FFDM system was less than the DSCRM system.

Objective To compare imaging quality and radiation dose of different anode filter combination for full-field digital mammography.MethodsThe image of FLUKE NA 18-220 phantom were taken at full-field digital mammography (FFDM),system with Mo/Mo,Mo/Rh,Rh/Rh anode/filter combination by automatic exposure control,record the exposure factors and doses.The images on monitor with the best window width and window level were read by 4 independent radiologists,the images of specks groups,nylon fibers and masses was assessed by the 4 experienced readers at the criterion of American College of Radiology 1999 mammography quality control manual.Statistical analysis was performed using analysis of variance.ResultsThe nylon fibers scores of Mo/Mo,Mo/Rh and Rh/Rh were 5.50 ± 2.12,4.50 ± 1.85 and 4.38 ± 1.38 ; the specks groups scores of Mo/Mo,Mo/Rh and Rh/Rh were 5.38 ± 1.98,4.25 ± 1.56 and 4.38 ± 1.38;the masses scores of Mo/Mo,Mo/Rh and Rh/Rh were 5.38 ± 1.98,4.38 ±1.68 and 4.25 ± 1.56,the detection of specks groups,nylon fibers was not statistically significant ( F =4.56 and 4.32,P ＞ 0.05 ),but the detection of masses was statistically significant ( F =36.65,P ＜ 0.05).The radiation doses were different,the entrance surface dose (ESD) and average glandular dose (AGD) of Rh/Rh were (5.11 ± 1.89) and ( 1.08 ± 0.13 ) mGy,the ESD and AGD of Mo/Mo were (6.66 ± 2.33 )and ( 1.29 ± 0.38 ) mGy,the ESD and AGD of Mo/Rh anode/filter combination were (5.67 ± 2.02) and ( 1.29 ± 0.38) mGy.ConclusionsThe radiation dose of Rh/Rh and Mo/Rh anode/filter combination of FFDM were lower,and the imaging was clear,so Rh/Rh and Mo/Rh anode/filter combination of FFDM prefer to mostly patients,especially when the thinkness is large,Rh/Rh anode/filter combination is preferred,because the kV values was higher,the penetration of X-ray was stronger.The Mo/Mo anode/filter combination was used when the needs of high-resolution,because the detection of masses of it was better.

Objective To investigate and analyze oral health status of inpatients with schizophrenia.Method We selected 105 patients from Beijing Anding hospital included hospitalization length 1-5 years group (39 cases) and hospitalization length over 5 years (55 cases) were investigated with Self-made questionnaire and assessment guide for psychiatric care (OAG-PC).Results Tooth loss and oral health status of schizophrenia inpatients were both poor.There was significant difference in the number of people with tooth loss (x2 =7.68,P ＜ 0.05) and mean number of tooth loss (F =9.20,P ＜ 0.05) between two groups.The OAG-PC total score (F=11.1,P＜ 0.05),odour from the mouth (F=4.34,P＜ 0.05),saliva (F=3.93,P＜ 0.05),mucous membranes (F=5.64,P＜ 0.05),teeth or dentures (F=5.34,P＜ 0.05),calculus on teeth (F=15.34,P ＜ 0.05),looseness of teeth (F =14.14,P ＜ 0.05),and No.of teeth in the lower jaw (F =7.70,P ＜ 0.05) in the schizophrenia inpatients with hospitalization length 1-5 years group was better than those with hospitalization length over 5 years,there were significant difference between two groups.There were no significant difference in lips (F =0.69,P ＞ 0.05),tongue (F =0.65,P ＞ 0.05),gums (F =1.87,P ＞ 0.05),appearance of teeth (F=1.52,P＞ 0.05),and No.of teeth in the upper jaw (F=3.58,P ＞ 0.05) between two groups.Conclusions Patients with schizophrenia are special vulnerable people.The more course of the disease was longer,the more the oral health status was worse.Tooth loss,calculus,and looseness of teeth are much more serious and will influence chew function seriously.Society,medical institutions,and families should pay more attention to the oral health status of patients with schizophrenia.And taking the preventative measures against poor oral health can improve quality of life of patients with schizophrenia.

Objective Our study was aimed to study the clinical effect of carbon dioxide laser in the treatment of adult laryn -geal papilloma . Methods Clinical data of patients with adult laryngeal papilloma received treatment at our hospital from January 2012 to June 2014 was retrospectively analyzed .Patients were divided into two groups according to the type of treatment , observation group:received carbon dioxide laser treatment;control group:received tumor forceps treatment .Participants included 61 cases of pa-tients, the observation group of 26 cases, control group 35 cases.Compare the general clinical data , short-term clinical effects(opera-tion time, length of hospital stay , complications , short-term curative effect ) , the change of immune inflammation indexes before and after operation and postoperative recurrence in 1 year of two groups patients. Results The operation time and the length of hospital stay in observation group was significantly lower than that in control group[(33.66 ±4.71)min vs (37.19 ±5.21)min,(4.07 ±1.25)d vs (4.83 ±1.38)d, P<0.05].On the 3th day, The levels of CRP、IL-6、TNF-αand IL-1βin observation group were ( 6.15 ±1.67 ) mg/L, (6.51 ±1.12)ng/L, (23.56 ±4.16)ng/L, (5.25 ±1.21) ng/L, those in control group were (12.20 ±3.41)mg/L, (15.63 ±
4.11) ng/L, (36.16 ±7.37) ng/L, (12.63 ±4.12) ng/L.The differences of these parameters between the two groups were signifi-cant (P<0.001).Observation group patients had a lower rate of recurrence 1 year after surgery than that of control group patients (12.00%vs 37.93%, P=0.029). Conclusion In the treatment of adult laryngeal papilloma , carbon dioxide laser can achieve a better minimally invasive and lower postoperative recurrence when compare to tumor forceps treatment .

Objective To improve the diagnostic ability of leukoencephalopathy with cerebral calcifications and cysts (LCC),a rare central nervous system disease.Methods The clinical manifestations,neuroimages and neuropathological features of a 19-year-old male patient were analyzed.A total of 20 cases from 14 literatures were reviewed.Results The patient was admitted with right limb weakness,cognitive decline,headache and blurred eyesight.Head CT scan showed multiple calcifications,cysts formation and leukoencephalopathy.Brain MRI showed several cysts in bilateral hemisphere,basal ganglia,thalamus and paraventricular areas.A mural nodule was noted inside one of the cyst,which was enhanced on the contrasted MRI.The wall of the cysts was partially enhanced,but not with the fluid inside the cysts.The corresponding CT calcifications foci showed on T1 and T2 with either both hyperintensity or both hypointensity,which was also partial enhanced.Extensive leukoencephalopathy was formed around the cysts and the ventricles.But neither Cho nor NAA changed a lot on MRS.Amplitude diagram of SWI series exhibited multiple round small dark signals all over the affected areas with mixed signals showed in the phase diagram,which indicated both calcifications and microbleedings at the lesions.Neuropathological examinations found no tumor cells in the operated cyst,and showed angiomatous small blood cells were dominant in the cyst wall.Hyaline degenerations,microcalcifications and hemosiderin deposition were observed.No obvious demyelination was discovered,while gliosis,numerous Rosenthal fibers and fibrinoid vascular necrosis were found around the lesions.The clinical,neuroimaging and pathological features of this patient were in accordance with the cases reported in the literatures.Conclusions Neuroimaging is the most important method for the diagnosis of LCC.As small vessel lesions are probably closely related to the pathophysiology of LCC,SWI could be recommended to further reveal the etiology of LCC.
