Objective To review and summarize the experiences of transcatheter closure of left ventricular-right atrium communication,and discuss the feasibility of interventional therapy for this kind of cardiac abnormalitis.Methods 22 patients who suffered from left ventricular-right atrium communication underwent transcatheter interventional therapy with ventricular septal defect(VSD) occluder.The operating procedures were performed as like as the transcatheter closure of VSD:established the pathway from femoral artery to femoral vein through left ventricle,VSD,right atrium (or from left ventricle to right atrial through the communication) and inferior vena cava,then inserted the polysheath from femoral vein,introduced by the pathway to left ventricle,and implanted VSD occluder through the polysheath to close the shunt.Results The operation succeeded in 21 patients.The cardiac murmur was disappeared in all patients,and there was no residual shunt or aortic regurgitation that conformed by postoperative ventriculography and echocardiography in follow up phase,and the tricuspid regurgitation was lessened than preoperative.The operation abort in 1 patient because of aortic regurgitation after implanting occluder.Conclusions Transcatheter closure of left ventricular-right atrium communication is feasible as the selected occluder is accordant,and atrioventricular block,aortic regurgitation and tricuspid regurgitation can be avoided.

Objective To study the Sheng Mai San on the levels of cell factors induced by lipopolysaccharide in acute liver failure rats. Methods The models of chronic liver failure were constructed by injecting CCl4 in the abdomen of rats. The serum levels of lipopolysaccharide and cell factors were determined after treating with LPS and Sheng Mai San for 2 hours. Results The serum level of IL-6［(64.50±18.79)pg/ml vs (4.79±0.57)pg/ml］, ICAM-1［(25100.00±5258.85)pg/ml vs (4215.50±942.79)pg/ml］ and TNF-α［(17.55±2.39)pg/ml vs (10.92±5.02)pg/ml］ was increased by CCl4 (P＜0.05), but there is no effect on the serum level of LPS in rats ［(0.058±0.007)EU/ml vs (0.040±0.002)EU/ml,P＞0.05］. Sheng Mai San can significantly reduce the serum level of IL-6, ICAM-1 and TNF-α in rats with acute liver failure induced by CCl4 ［(17.20±3.12)pg/ml,(9490.00±2725.78)pg/ml,(3.00±1.00)pg/ml,P＜0.05］. After treating with LPS for 2 hours, the serum level of LPS, TNF-α, IL-6, ICAM-1 markedly increased ［(0.501±0.019)EU/ml,(19750.00±9655.17)pg/ml,(5615.00±490.50)pg/ml,(41000.00±589.88)pg/ml,P＜0.01］. Sheng Mai San could reduce the serum levels of LPS, TNF-α, IL-6, ICAM-1 and in rats with chronic liver failure (P＜0.01). Conclusions SD Rats in the state of chronic liver fail-ure, existing serious serum endotoxin, can induce the levels of cell factors by diversification inflammation reaction and.

ObjectiveTo evaluate the application of multi-slice CT (MSCT) perfusion scan technique in predicting renal function recovery after unilateral hydronephrosis treatment.MethodsThirtyeight patients with unilateral obstructive hydronephrosis not shown on intravenous urography (IVU) and a normal contralateral kidney were recruited for this study.Patients were divided into detected (D) and undetected (UD) groups depending on whether the IVU detected urinary tract obstruction.All patients underwent plain abdominal X-ray,gray-scale ultrasonography,excretory urography and MSCT perfusion scan before and after the treatment.Patients were followed-up at six months or more after the treatment for a mean duration of 12.5 months (range from 6 to 22 ).ResultsOf the 38 cases,22 cases were in group D,16 cases were in group UD.On MSCT,renal cortex blood flow (BF) and blood volume ( BV ) value after treatment in group D were 561.1 ± 165.4 ml/( 100 g · min) and 35.9 ± 11.3 ml/100 g compared with before treatment rates of 361.6 ±109.7 ml/(100g· min) and24.1 ±10.2 ml/100g,t=-3.38,-2.34,P＜0.01,0.05.In the UD group,the differences of these parameters were after treatment 38.7 ± 15.4 ml/(100 g · min),10.306 ± 4.925 ml/100 g and before treatment 39.1 ± 22.5 ml/( 100 g · min) and 8.7 ± 4.4 ml/100 g,P ＞ 0.05.In the aspects of BF and BV,there were statistically significant differences between group D and group U D both before and after the treatment,t=9.09,4.15,P ＜ 0.01.ConclusionsM SCT perfusion can provide a valuable prediction technique of the renal function recovery in patients with unilateral obstructive hydronephrosis.Improvement of renal function can be expected after relief of obstructive hydronephrosis if the patients have a BF 361.6 ml/( 100 g · min) and BV 24.1 ml/100 g or greater measured by MSCT perfusion.

Objective To evaluate effect and safety of first-line chemotherapy regimen combined with rh-endostatin for osteosarcoma of the extremities.Methods Sixty three patients with osteosarcoma were randomly divided into experiment group and control group.There were 32 patients in experiment group,and 31 patients in control group.Nine patients 9 were rejected because they did not meet the standard.Finally,54 patients were enrolled in this study,including 29 patients in experiment group,and 25 patients in control group.In the experiment group,the patients were treated with rh-endostatin combined with MTX,IFO,DDP,and ADM,while patients in control group were treated with MTX,IFO,DDP,and ADM.Several indexes including median progression-free survival time,clinical benefit rate,progression-free survival rate,limb salvage rate,and survival rate were used to assess clinical effect.The safety of rh-endostatin was evaluated by comparing incidence of adverse events in the two groups.Results The median progression-free survival time of experiment group and control group was 18.9 months and 13.1 months,respectively; there was no significant difference.In the experiment group,the clinical benefit rate,progression-free survival rate,survival rate and limb salvage rate were 89.7％,37.9％,65.5％,and 89.7％,respectively; while in the control group,the clinical benefit rate,progression-free survival rate,survival rate,and limb salvage rate were 88.0％,36.0％,68.0％,and 96.0％,respectively.There was no significant difference in 4 indexes mentioned above between two groups.Conclusion After being combined with first-line chemotherapy regimen,rh-endostatin doesn't show significant advantage in controlling tumour progression and improving survival rate.No more toxicity and new side effects are found after using rh-endostatin.

Objective To assess the prognostic value of C-reactive protein/albumin (CRP/Alb) ratio in patients with clear cell renal cell carcinoma (ccRCC).Methods The study comprised 406 ccRCC patients undergoing nephrectomy between January 2003 and December 2012 in our hospital.There were 253 males and 153 females,aged 24-80 years,with a median age of 58 years.There were 355 cases with TNM Ⅰ stage,38 cases with Ⅱ stage,30 cases with Ⅲ stage,3 cases with Ⅳ stage.There were 376 cases with tumor necrosis and 40 cases without tumor necrosis.There were 395 cases of vascular invasion,21 cases without vessel invasion.The correlations among the pretreatment CRP/Alb ratio,clinicopathological parameters,and overall survival (OS) were evaluated.We compared the prognostic value of the CRP/Alb ratio with GPS and mGPS using the area under the curve (AUC).Results CRP/Alb ratio was associated with age at surgery (P =0.007),TNM stage (P ＜ 0.001),tumor necrosis (P ＜ 0.001) and lymphovascular invasion (P ＜ 0.001),and OS (P ＜ 0.001).The multivariate analysis confirmed that the CRP/Alb ratio independently predicted the OS of patients with ccRCC (P ＜ 0.001),the Glasgow prognostic score (GPS) (P =0.001) and modified GPS (mGPS) (P =0.019) were also independent prognostic factors.For predicting 3-year survival,the AUC values for CRP/Alb (continuous),CRP/Alb (categorical),GPS and mGPS were 0.88,0.84,0.85,0.80.For predicting 5-year survival,the AUC values for CRP/Alb (continuous),CRP/Alb (categorical),GPS and mGPS were 0.80,0.79,0.76,0.72.The CRP/Alb ratio was superior to GPS and mGPS in predicting the 3-or 5-year survival rate of ccRCC patients.Conclusions The CRP/Alb ratio could be an independent prognostic factor in ccRCC patients.The CRP/Alb ratio could take the place of the GPS and mGPS in terms of predicting prognosis in ccRCC.

Objective:To investigate the application value of fixation mesh with suture anchor in the repair of parailiac hernia.Methods:The retrospective and descriptive study was conducted. The clinical data of 5 patients with parailiac hernia who were admitted to Shaoxing People′s Hospital from March 2016 to February 2019 were collected. There were 4 males and 1 female, aged from 23 to 67 years, with a median age of 49 years. Patients underwent repair of parailiac hernia, in which mesh with suture anchor was fixed on the outside of the defect to the inner side of the ilium. Observation indicators: (1) surgical and postoperative conditions; (2) follow-up. Follow-up using outpatient examination or telephone interview was conducted at postoperative 1 week, at postoperative 2 weeks, at postoperative 1, 3, 6 months, at postoperative 1 and 2 years, respectively. The follow-up was up to July 2019. During the follow-up, the conditions about drainage tube removal, incision infection, hernia recurrence, and chronic pain were observed. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M (range). Results:(1) Surgical and postoperative conditions: 5 patients underwent surgeries successfully, without blood transfusion. The volume of intraoperative blood loss was 100 mL(range, 20-300 mL). The operation time and duration of drainage tube placement were (129±13)minutes and (13.8±1.9)days. Patients were discharged from hospital, without postoperative complications during the hospital stay. The duration of hospital stay was 13 days(range, 8-19 days). (2) Follow-up: patients were followed up for 4-39 months, with a median follow-up time of 16 months. One of the 5 patients was removed drainage tube during the hospital stay and other 4 patients were removed at the outpatient after discharge from the hospital. One patient felt numbness in the surgical site at postoperative 1 month without aggravation during the follow-up, and received no specific treatment. Four patients completed computed tomography examination at postoperative 6 months, without hernia recurrence. There was no incision infection or chronic pain.Conclusions:It is safe and effective to use fixation mesh with suture anchor in the repair of parailiac hernia.

Objective:To explore the changes of dynamic cerebral autoregulation ability in pilots exposed to acute positive acceleration(+ Gz) by transcranial Doppler combined with beat-to-beat blood pressure.Methods:A total of 26 pilots enrolled in the + 8Gz manned centrifuge trial at the Air Force Medical Center, Air Force Medical University from June to October 2022 were prospectively included. Blood pressure and heart rate were monitored in the resting state before the trial and within 5 min after centrifugation. Transcranial Doppler combined with noninvasive continuous beat-to-beat blood pressure monitor were used to detect bilateral middle cerebral artery blood flow velocity and beat-to-beat pulse pressure respectively. The transfer function analysis was applied to derive the parameters of cerebral blood flow autoregulation in each frequency band from 0.02 to 0.50 Hz, and the phase, gain and coherence were calculated. The above parameters were compared between resting state and after acute + 8Gz positive acceleration exposure.Results:Compared with the resting state, in all of the 26 pilots after acute + 8Gz positive acceleration exposure, the systolic and diastolic blood pressure and heart rate increased significantly ( P<0.001), the phase significantly increased and the gain significantly decreased in the ultra-low frequency band (0.02-0.07 Hz) ( P<0.05); whereas there were no statistical differences of gain and phase in the low frequency band (0.07-0.20 Hz) and the high frequency band (0.20-0.50 Hz) (all P>0.05). Conclusions:Transcranial Doppler combined with beat-to-beat pulse pressure can be used for the assessment of changes in immediate dynamic cerebral autoregulation after acute + Gz exposure, and transfer function analysis of ultra-low frequency band parameters is suitable for this type of evaluation.

The hidden risk of acupuncture has become the factor of the high incidence of adverse reaction of acupuncture in clinical practice. The retrospective analysis and the typical cases analysis are especially important for the prevention from the hidden risk of acupuncture. In the paper, the relevant literatures were reviewed, the basic diseases were listed such as diabetes, hypertension and digestive gastric ulcer that were neglected by the physicians, and the adverse reactions induced by the therapeutic history and the body constitutions were analyzed. It was stated in the paper that because of the individual factors of patient, the risks of the atypical clinical accidents of acupuncture were extremely serious and easily neglected by the clinical acupuncture physicians. It is very necessary to remind the clinical acupuncture physicians to understand the basic diseases, basic treatment as well as the peculiarity of body constitution of the patients besides their chief complaints. Moreover, acupuncture should be applied very carefully after identifying the pulse condition and the contraindication so as to ensure the patient's safety and obtain the optimal efficacy.
