Clinically,the incidence of portal vein thrombosis(PVT)in patients with cirrhosis can be up to 10％-23％.When PVT is not treated promptly,it may develop to cavernous transformation of the portal vein(CTPV).CTPV can aggravate portal hypertension,accelerate the progression of esophagogastric varices bleeding,refractory ascites,refractory peritonitis,biliary tract diseases,and hepatic insufficiency.At present,noninvasive imaging techniques such as portal vein reconstruction,enhanced CT and ultrasound are mostly used to make the diagnosis and evaluation of CTPV.It is rather difficult to perform portosystemic shunt surgery in patients with CTPV complicated by portal hypertension,which was once regarded as a contraindication for interventional portosystemic shunt procedures.With the improvement of related technologies and surgical instruments,the transjugular intrahepatic portosystemic shunt(TIPS)has become an important treatment for CTPV.This paper aims to make a comprehensive review about the relevant researches concerning the portosystemic shunt surgery in patients with CTPV so as to clarify the importance of TIPS in the treatment of CTPV.

A 58-year-old female patient with breast cancer received treatment with pegylated recombinant human granulocyte colony-stimulating factor(PEG-rhG-CSF)injection after adjuvant chemotherapy.The serum creatinine level of the patient gradually increased from the normal baseline value to 199.3 μmol·L-1.The patient was diagnosed as acute kidney injury(AKI),after stopping the medication and providing symptomatic treatment,the patient's renal function gradually improved.The patient completed subsequent chemotherapy as planned without reusing PEG-rhG-CSF injection,and other medications and dosages remained unchanged.Renal function remained stable during follow-up.Naranjo's Assessment Scale was used to evaluate the association between PEG-rhG-CSF injection and AKI,the result was"probable."There are few reports of AKI occuring with PEG-rhG-CSF injection,and this case provides evidence for clinical safe medication.

Subjective visual gravity detection includes subjective visual vertical(SVV)detection and subjec-tive visual horizontal(SVH)detection,which refers to the detection of the angle between patients' perceived gravity vertical line and gravity horizontal line and the actual gravity vertical line and horizontal line when people exclude vis-ual reference and in dark environment.The results are used to evaluate the function of the utricle of the subjects,and then provide the basis for diagnosing vestibular system diseases.With the continuous improvement of SVV &SVH examination technology and the understanding of the mechanism,SVV & SVH examination has been widely applied to clinical work.At present,there are some progresses of srvesvit SVV & SVH in the diagnosis,evaluation and treatment of diseases of the vestibular system such as vestibular neuronitis,Meniere disease and benign paroxys-mal positional vertigo(BPPV),and this article reviews these progresses.

Objective:To analyze the clinical characteristics of children with systemic lupus erythematosus (SLE) combined with thrombotic microangiopathy (TMA), and clarify the clinical outcomes and related risk factors of pediatric patients through their treatment and follow-up.Methods:This was a single-center retrospective case-control study. Children diagnosed with SLE combined with TMA between January 2017 and January 2023 at Beijing Children′s Hospital, Capital Medical University, were selected as the TMA group, and SLE children without TMA were selected as the control group.According to the prognosis, children in the TMA group were further divided into the good prognosis group and the poor prognosis group.The data of the children were collected, including age, gender, SLE disease activity, clinical presentations at the time of diagnosis and at the time of thrombosis, laboratory examinations, treatment strategies, prognosis, and follow-up results.The chi-square test and Z-test were used for comparison of count data.The t-test was used for comparison of metrological pairing data.The Fisher′s exact test was used to compare the differences between the 2 groups in categorical variables.The univariate Logistic regression was used to analyze the risk factors of poor prognosis. Results:There were 29 cases in the TMA group, and the incidence of TMA accounted for 2.53% of SLE patients; 33 cases were in the control group.The age at diagnosis of TMA was 13 years and 5 months (ranging from 9 years, 1 month and 5 days to 17 years and 4 months).The common clinical manifestations in order of prevalence were renal involvement (28 cases, 96.55%), hematologic involvement (26 cases, 89.66%), serous effusion (17 cases, 58.62%), rash (13 cases, 44.82%), and neurologic involvement (12 cases, 41.38%).Pleurisy or pericarditis, renal involvement and neurological involvement occurred more often in the TMA group than in the control group (17 cases vs.3 cases, 28 cases vs.10 cases, 12 cases vs.3 cases), and the TMA group showed less facial rash and arthritis than the control group (13 cases vs.25 cases, 4 cases vs.17 cases), and the differences were statistically significant (all P<0.05).The Systemic Lupus Erythematosus Disease Activity Index score in the TMA group [(24.14±9.42) scores] was significantly higher than that in the control group [(10.18±9.42) scores], and the difference was statistically significant ( t=3.233, P<0.05).The hemoglobin level, platelet count, and complement C3 level of the children in the TMA group were significantly lower than those in the control group, whereas the double stranded DNA antibody, lactate dehydrogenase, D-dimer, urea, creatinine, ferritin level, and urine protein quantitation were significantly higher than those in the control group, and the differences were statistically significant (all P<0.05).In the TMA group, 5 cases had decreased ADAMTS13 activity, and 5 cases had significantly increased complement C5b9.A total of 15 cases (51.72%) in the TMA group underwent renal biopsy, and 13 of them had combined renal TMA.In the TMA group, 28 patients (96.6%) received hormone therapy, 17 patients received plasma exchange, and 12 patients were treated with immunosuppressants and biologics; 19 patients (65.5%) improved, and 10 patients (34.5%) gave up the treatment due to deterioration of the disease.The urea level and peripheral blood fragmented erythrocyte rate in the good prognosis group were significantly lower than those in the poor prognosis group [(13.18±4.39) mmol/L vs.(21.16±10.14) mmol/L, t=2.975, P=0.006; 8/17 (47.06%) vs.7/7 (100%), χ2=5.929, P=0.015].The univariate Logistic regression analysis showed that the fragmented erythrocyte, ADAMTS13 activity and urea were the independent risk factors for poor prognosis (all P<0.05). Conclusions:SLE patients with moderate-to-severe disease activity, especially children with hemolytic anemia, thrombocytopenia, and renal dysfunction as prominent manifestations, should be alert to the risk of TMA.Early diagnosis and treatment are crucial.

Objective:To evaluate the recovery of daytime and nighttime urinary continence in patients with robotic-assisted radical cystectomy and ileal orthotopic neobladder from 1 to 60 months after surgery, and systematically analyze the influencing factors of daytime and nighttime urinary continence recovery.Methods:The convenient sampling method was used to select clinical data of 60 patients who underwent robotic-assisted radical cystectomy and ileal orthotopic neobladder by a single operator from December 2014 to January 2020 and they were followed up for daytime and nighttime use of urine pads and prognosis. A total of 44 patients were eligible for follow-up data. Satisfactory recovery of daytime and nighttime urinary continence was defined as the use of less than or equal to 1 pad, and complete recovery of daytime and nighttime urinary continence was defined as no urine leakage. The daytime and nighttime urinary continence recovery in patients with robotic-assisted radical cystectomy and ileal orthotopic neobladder was assessed at 1, 3, 6, 12, 24, 36, and 60 months. Cox regression was used to analyze the influencing factors of postoperative urinary continence recovery.Results:Cox regression multivariate analysis showed that preservation of neurovascular bundles was associated with satisfactory recovery of daytime urinary continence, satisfactory recovery of nighttime urinary continence and complete recovery of daytime urinary continence ( P<0.05) . Clevien grading of complications within 90 d could affect the satisfaction of daytime urinary control recovery. Preoperative hydronephrosis was an independent factor affecting the satisfaction of nighttime urinary continence recovery. Conclusions:Preserving neurovascular bundles is an influencing factor in promoting postoperative urinary continence recovery in patients with robotic-assisted radical cystectomy and ileal orthotopic neobladder. In addition, postoperative complications and preoperative hydronephrosis are independent factors affecting the satisfaction of daytime and nighttime urinary continence recovery, respectively, but it need to be further confirmed by multicenter prospective studies.

Objective:To examine the clinical application effects of two-complex and one-plane technique for the renal artery dissected location in transperitoneal laparoscopic radical nephrectomy(LRN).Methods:Clinical data of patients diagnosed as renal tumor between January 2016 and December 2019 that treated with transperitoneal LRN and the two-complex and one-plane technique was performed to locate and dissect the renal arteries were analyzed retrospectively. A total of 206 qualified patients were enrolled, included 71 cases from Kaifeng Central Hospital and 135 cases from the First Affiliated Hospital of Zhengzhou University. There were 126 males and 80 females with median age of 54 years (range: 35 to 82 years). Renal tumor lived at left kidney in 102 cases and at the right in 104 cases, with a maximum tumor diameter of (6.8±2.5)cm (range: 3.0 to 12.7 cm). During the procession of transperitoneal LRN, The genital veins was followed to locate renal veins, soon the renal vein complex and renal lower pole complex and psoas major muscle plane that named as “two-complex and one-plane”anatomical markers were applied to the dissected location of renal arteries. The established application of two-complex and one-plane technique for renal artery location, and the anatomical features along with its locational time of renal artery, as well as vascular-related complications were recorded and analysed. The χ 2 test or t test was used to compare the results of different lateral operations. Results:The surgical procedures were successful in all 206 patients. The operation time was (54.4±13.6) minutes (range:22 to 116 minutes), no injury to liver, spleen or intestine. Two-complex and one-plane technique was used to complete renal arteries location of 206 patients that accompanied with one or more arterial branch in the procession of transperitoneal LRN. Single renal artery branch was found in 163 cases, two or more renal artery branches were found in 43 cases, and 60 branches of accessory renal artery that in addition to the main trunks were detected in 14 cases (13.7%, 14/102) on left-side and 29 cases (27.9%, 29/104) on the right(χ2=6.251, P=0.012).The main branch of renal artery that directly been located inferior or posterior to renal vein in 165 cases, and the other 41 cases that born with higher-position of main branch been located through an upper“window-opening”of renal veins complex. Of the 60 accessory renal artery, 46 branch (76.6%, 46/60) been located inferior or posterior to renal veins, and the other 14 branch with higher-position (23.3%, 14/60) been located by a"window-opening"technique. The renal artery dissected location time was (21.2±9.4) minutes (range:11 to 43 minutes) in left-side and (17.5±9.3) minutes (range:9 to 32 minutes) in the right ( t=2.840, P=0.005).The intraoprative bleeding was (51.8±25.2) ml (range:20 to 400 ml). There were 4 cases of vascular injury occured and treated with laporoscopy, only one need blood transfusion. Conclusions:The anatomical markers of renal vein complex and renal lower pole complex and psoas major muscle plane that can apply to locate various anatomical position types of renal artery in transperitoneal LRN effectively. The exactly application of two-complex and one-plane technique that could shorten the operational time of renal artery location and reduce the complications of vascular injury.
