Objective To explore the effect and indication of splenectomy in liver transplantation.Methods From January 2001 to April 2006,260 patients underwent piggyback orthotopic liver transplantation(PBOLT),and 28 patients had undergone combined PBOLT and splenectomy(splenectomy group).These patients were compared to 56 randomly selected non-splenectomy patients from the same transplant period,meaningly two controls were se- lected for every non-spleneetomy case.Two groups were analyzed with respect to rate of infection and survival rate, as well as biopsy-proven acute allograft rejection within 30 days after transplantation.Results Rate of infection in the splenectomy group was higher than that in the non-splenectomy patients(85.7% vs 55.4%,P

BACKGROUNDResearches in ocular electromyography (EMG) and Magnetic resonance imaging (MRI) of patients with Duane retraction syndrome (DRS) suggest that there may be additional abnormalities such as paradoxical innervation between horizontal rectus muscles and vertical rectus muscles, hypoplasia of vertical rectus muscle and that oblique muscles may also contribute to the heterogeneity of the clinical manifestation of DRS. This paper reports the results of superior rectus recession for vertical deviation and A pattern in DRS Type III and discusses the pathogenesis of the disease.
METHODSSuperior and lateral rectus recession were performed in 5 cases of Huber type III DRS to treat vertical deviation and A pattern strabismus. Before operation, MRI of the brain, brainstem, cavernous sinus, and orbits were performed.
RESULTSAll subjects had unilateral limitation of both abduction and adduction, with palpebral fissure narrowing and globe retraction in adduction. Three cases had A pattern of strabismus, three cases had hypertropia. The abducens nerves (CN6) were either absent or hypoplasitic in the brainstem in all patients. Two eyes had larger oculomotor foramen. Two eyes had hypoplasia of the superior rectus and the inferior rectus. There was presumably a branch of the third cranial nerve (CN3) innervating the lateral rectus (LR) in one eye. While in another eye, two branches of CN3 sent into medial rectus were revealed. After surgery, vertical deviation in the primary position was reduced in all patients and A pattern was eliminated in 3 patients. One patient developed 10Δ consecutive esotropia postoperatively.
CONCLUSIONThe results suggest that structural abnormalities of vertical muscle and abnormal orbital innervation may be related to vertical deviation and the presence of A pattern in DRS type III. Recession of the superior rectus muscle seems to be a safe and effective treatment for vertical deviation and A pattern strabismus in DRS Type III.

4.Air tamponade with inverted internal limiting membrane flap technique for macular hole retinal detachment in high myopia with posterior staphyloma
International Eye Science 2022;22(4):536-540
AIM: To evaluate the effect of vitrectomy with inverted internal limiting membrane(ILM)flap technique and air tamponade in high myopic eyes with macular hole retinal detachment(MHRD).METHODS: A retrospective, noncomparative study of high myopia patients with MHRD was conducted. In all cases, triamcinolone acetonide was used to visualize the vitreous during vitrectomy. After ILM was inverted, a venous blood clot was placed on the inverted ILM flap and air was used as tamponade. Macular hole closure rate, retinal reattachment rate, and postoperative best-corrected visual acuity(BCVA)were assessed after the surgery.RESULTS: Twenty-four eyes of 24 high myopia patients with MHRD were included in this study. The patients were followed up for at least 6mo, averaging 13.58±7.00mo. At last follow up,macular hole(MH)was closed in 21 eyes(88%)and retina was reattached in 20 eyes(83%). Seventeen eyes(71%)had both complete MH closure and retinal reattachment. Three eyes(13%)had complete reattached retina with unclosed MH, while 4 eyes(17%)had persistent subretinal fluid with closed MH. No additional pars plana vitrectomy(PPV)was performed. BCVA(LogMAR)was significantly improved at last follow up(0.65±0.34 vs 1.36±0.49, P<0.001). An improvement in BCVA of 2 or more lines was achieved in 12 eyes(50%).CONCLUSION:Vitrectomy combined with inverted ILM flap, autologous blood transplantation and air tamponate is an effective treatment for MHRD in myopic eyes.

BACKGROUNDWith the technical advances, magnetic resonance imaging (MRI) is now sensitive enough to detect subtle structural abnormalities of ocular motor nerves arising from the brainstem and orbits of living subjects. This study was designed to delineate the MRI characteristics in patients with special forms of strabismus.
METHODSA total of 29 patients with special forms of strabismus underwent orbital and intracalvarium MRI. Imaging of the ocular motor nerves in the brainstem was performed in 0.8 mm thickness image planes using the three-dimensional fast imaging employing steady-state acquisition (3D-FIESTA) sequence. Nerves to extraocular muscles (EOMs), EOMs and their associated connective tissues were imaged with T1 weighting in tri-planar scans by dual-phased coils within 2.0 mm thick planes.
RESULTSPatients with congenital fibrosis of the extraocular muscles exhibited hypoplasia of the oculomotor (CN3), abducens (CN6), trochlear (CN4) nerves, and the EOMs; hypoplasia of CN6 in the brainstem and an extra branch of the inferior division of CN3 to the lateral rectus were the most common but not the only presentation of Duane's retraction syndrome. Hypoplasia of CN6, facial (CN7) and hypoglossal (CN12) nerves were revealed in patients with Möbius syndrome. In a rare case of bilateral synergistic convergence and divergence, an enlarged branch of CN3 to the medial rectus and a questionable branch of CN3 to the inferior rectus bilaterally were found.
CONCLUSIONMRI can reveal subtle structures of the ocular motor nerves and their corresponding EOMs. This can provide valuable information regarding pathogenesis in some special forms of strabismus.

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.
METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.
RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).
CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.
