Objective To evaluate the therapeutic efficacy of agitating thrombolysis technique for Budd-Chiari syndrome complicated with inferior vena cava (IVC) fresh thrombus. Methods From August 2004 to March 2009, 5 patients of Budd-Chiari syndrome (four males and one female, aged 36-48 years) with IVC fresh thrombus were treated with agitating thrombolysis technique. After anpography of IVC the recanalization of IVC was performed, which was followed by agitating thrombolytic therapy. Finally,IVC was dilated with percutaneous transluminal balloon angioplasty. Clinical follow-up of IVC patency was conducted by color Doppler sonography. Results After agitating thrombolysis. The thrombi were completely disappeared in all 5 patients without single occurrence of pulmonary embolism. In all patients, IVC remained patency on color Doppler ultrasonograph after following up for a mean period of 23.8 months. Conclusion Agitating thrombolysis technique is a safe and effective treatment for Budd-Chiari syndrome complicated with IVC fresh thrombus.

Objective:To explore the safety and efficacy of Castor branched stent-graft exclusion in the treatment of aortic dissection and aneurysm involving left subclavian artery.Methods:The clinical and imaging data of 88 patients with aortic dissection or aneurysm involving left subclavian artery diagnosed by CTA or DSA in our hospital from December 2017 to December 2019 were collected retrospectively, including 67 aorta dissections, 7 thoracic aortic aneurysms and 14 aorta penetrating ulcer. All patients were treated with branched stent-graft under the guidance of DSA. The postoperative curative effect and complications were observed. The paired t test was used to compare the maximum aortic diameter of the lesion before and 6 months after the operation. Results:Eighty-eight patients were successfully treated with integrated stent, the success rate of operation was 100%, and the disease-related symptoms of all patients were basically or completely relieved. The mortality rate within 1 month after the operation was 2.7% (2/88). The two deaths were complicated with other serious diseases before the operation, and the cause of death was not related the operation. All patients were followed up except 4 patients who lost contact after discharge. During the follow-up, there were 1 case of retrograde type A dissection, 1 case of new aneurysm of aortic arch, 2 cases of in-stent stenosis of left subclavian artery branch, 3 cases of mild stroke, no persistent endoleak and no death or other serious complications. The mean maximum aortic diameter at 6 months after operation [(34±4)mm] was significantly lower than that before operation [(38±6 mm)] ( t=6.63, P<0.05). Conclusion:Castor branched stent-graft is simple, mini-invasive and effective in the treatment of aortic dissection and aneurysms involving the left subclavian artery.

Presented in this paper is a preliminary report on reliability study of comprehensive function evaluation.One hundred and five normal persons were evaluated twice in the interval of one month.The result revealed significant statistical difference,Kappa=0.79,u=7.938>2.56,P<0.01,demonstrating the substantial agreement of these two evaluations.The result suggests that the scale has substantial intra observer agreement and high reliability.The personal comprehensive function could be evaluated completely in the scale.It would be significant not only in practice but also in theory to improve the rehabilitation evaluation and rehabilitation medical level.

One hundred and fourty-nine normal persons were tested to gain the normal scale of Comprehensive Function Evaluation(CFE).It includes seven items eighteen categories.The result demonstrated that fifteen categories of normal persons in age of twenty to sixty-nine incuding understanding and expressing,feeding,grooming,dressing clothes,dressing trousers and skirts,bathing,bowel and bladder management,control of sphincter of bowel and bladder,bed wheelchair mobility,bathtub-wheelchair mobility,ambulation,up and down the stairs,which gained one hundred degrees each,memory ninty eight to one hundred degrees,problem solving ability eighty-four to one hundred degrees,social communication ninty-nine to one hundred degrees.We conclude preliminarily:CFE is an individual ability evaluation of preson,demonstrating the comprehensive function of presons which were in aga of twenty to sixty nine,educated in and above primary school.It can be used as a main scale to evaluate the guality and effect of rehabilitation sequence,and has practical value to improve rehabilitation medical level.

: Rehabilitation medicine is a medical branch which focused on functional recovery. Function Evaluation is very important in assessing the function of patients, the effect of treatment and the efficiency of rehabilitation. Comprehensive Function Evaluation includes evaluation of physical, psychological, speech and society. Vocal, mental and social evaluation have deep cultural and national background. Therefore every country must have its own Function Evaluation Method. Now we present our design for Comprehensive Evaluation. Based on the cooperation of Department of Rehabilitation, Department of Neurology, Department of Spinal Cord Injury, Department of Speech Therapy and Department of Psychology. The advantages of this method are as follows: 1. The style of ADL, speech and thinking are suitable for the condition of our country. 2. The evaluation result adopts hundred work system, it is easy for medical staff, patients and their family to understand and communicate the result. 3. We make it more accurate, comprehensive and reliable by some simple tests on speech pathology and psychology. 4. We overcome some disadvantages of evaluation indexes because it is not correct and is difficult to be understood before. Now every evaluation index has quantity standard. 5. It is simple and practical. Each subtest takes 20 minutes or more. 6. It has been tested by normal people. The norm and severity grade had been developed. 7. The reliability is tested and is proved to be dependable.

康复医学是以恢复患者功能为中心的医学分支。因此，功能评定无论是在客观地评定患者的功能方面，还是在最终评定治疗结果和康复效率方面都是极为重要的。全面的功能评定包括躯体、精神、言语和社会四个方面。其中，言语、社会功能和认知功能中的思维方式，都具有强烈的民族文化色彩。因此，每个国家都应该有切合自己国情的功能评定方法。但由于我国康复医学发展较晚，至今尚无一套既切合国情，又全面、实用和可靠的功能评定方法。有鉴于此，我们在“中心”顾问室、神经康复科、脊髓损伤康复科、言语治疗科、心理科和老年病科的通力合作下，经过近2年的研究，在吸收国际先进经验的基础上，密切结合国情，设计了本文所述的综合功能评定法。其优点有：1．在饮食、起居等生活方式方面以及在言语、社会、思维等方面，均切合我国国情。2．评定结果采用群众熟悉的100分制，使医务人员、患者和患者家属均易于理解，便于交流和沟通。3．在言语、认知等功能的评定方面，直接由言语和心理学家选择一些简易的言语和心理学测试项目，提高了量表的准确性、全面性和可靠性。4．各项评定指标的量化程度高，在言语、认知和社会方面尤其如此，克服了一些量表中对此类项目的评定指标不够具体和不易掌握的不足。5.简便实用，一次检查对正常人仅需20分钟左右，对患者则无负担。6.本法已在128名正常人中应用，并求出了正常值，据此拟定了功能障碍严重程度的等级，可供参考和应用。7.信度经过检验，证明可靠。 综合功能评定法的正常值、功能障碍严重程度分级及信度研究结果，将陆续报道。

Objective:To evaluate the safety and feasibility of intranodal lymphangiography combined thoracic duct embolization in the treatment of chylous leakage.Methods:The clinical data of ten patients with chylous leakage from July to December 2019 in the First Affiliated Hospital of Zhengzhou University were retrospectively analyzed. There were 6 cases of chylothorax, 1 case of chylous ascites, and 3 cases of chylothorax combined with chylous ascites, respectively. Conservative treatment was invalid in all cases. The locations of cisterna chyli and thoracic duct were defined by percutaneous puncture intranodal lymphangiography. Then the percutaneous transabdominal puncture of cisterna chyli was performed and the microcatheter was inducted. The location of fistula was visualized by thoracic duct lymphangiography, and the embolization was performed by microcoils combined tissue adhesive agents. The post-operative curative effect and complications were recorded.Results:One patient did not receive thoracic duct embolization because it was failed to visualize cisterna chyli by intranodal lymphatic angiography; thoracic duct embolization was successfully performed in the other 9 patients after chylous leakage fistula was located. Percutaneous transabdominal puncture of cisterna chyli was successfully accomplished in 8 patients. As for the other patient, after repeated failure of puncture, fluoroscopy-guided retrograde puncture at the proximal thoracic duct was performed successfully. After the operation, the drain output was completely disappeared within 3 to 7 days in 8 patients, and decreased down to 120 ml/d in 1 patient. Mild abdominal hemorrhage was found in 1 patient after thoracic duct embolization, without any treatment. No serious complications was found in all cases.Conclusion:Intranodal lymphangiography and thoracic catheter embolization is safe and effective in the treatment of chylous leakage, with a low complication rate.

Objective:To evaluate the feasibility, safety, treatment outcome, and the individualized surgical procedure selection of the interventional treatments of chylous leakage.Methods:From July 2019 to January 2022, the clinical data of 60 consecutive patients with chylous leakage underwent interventional treatment were respectively analyzed. The cases included chylothorax ( n=37), chylous ascites ( n=10), chyluria ( n=4), chylothorax combined with chylous ascites ( n=5), chylothorax combined with chylopericardium ( n=2), and pelvic chylous effusion ( n=2). Conservative treatment was considered to have failed for all patients. The lymphangiography was firstly performed to detect chylous leakage, then an individualized procedure was selected according to the lymphangiography results. The treatment outcomes and complications were recorded, and follow-up was performed. Results:Lymphangiography was technically successful in 55 of 60 patients (91.7%), and no cisterna chyli and thoracic duct opacification was observed in 5 patients. The procedures for the patients included lymphangiography alone ( n=23), thoracic duct embolization ( n=23), thoracic duct disruption ( n=5), lymphatic embolization for pelvic chylous effusion ( n=4), and balloon plasty for thoracic duct ( n=5). Clinical success was achieved in 53 of 60 cases (88.3%). The complication rate was 8.3% (5/60), and all complications were minor. The median follow-up time was 11 months (range 0.5-30 months) for 56 patients, and 4 patients were lost to follow-up. There was one patient presenting the reoccurrence of symptom, and 8 patients died. Conclusions:The interventional treatment of chylous leakage is safe with good outcomes and low complication rate. Individualized treatment procedures based on the lymphangiography findings is feasible and with good curative effect.

Objective:To investigate whether FcγRⅡb rs775 single nucleotide polymorphism confers susceptibility to Hashimoto′s thyroiditis and its impact on expression of FcγRⅡb protein on B cell surface.Methods:A total of 187 Hashimoto′s thyroiditis patients(HT group) were enrolled, including 46 males(24.60%) and 141 females(75.40%), with a median age of 43(32, 53) years, and 187 healthy controls(conrol group), including 62 males(33.16%) and 125 females(66.84%), with a median age of 41(31, 51) years. The peripheral blood of two groups were sequenced, genotype and allele frequencies distribution of FcγRⅡb rs775 T>C were compared with clinical parameters as strata between the two groups. At the same time, the expression of inhibitory receptor FcγRⅡb on B cell surface was detected using flow cytometry.Results:Compared with control group, the mutant homozygous CC genotype was obviously enrichment in HT group( OR=3.321, 95% CI 1.175-9.386, P=0.018), and the proportion of CC genotype increased in male of HT group( P=0.076). However, there is no significant difference in genotype and allele frequencies between control group and HT group after stratification by sex. In addition, the percentage of FcγRⅡb on B cell surface decreased significantly in HT group( P=0.029). Conclusion:There was no significant correlation between FcγRⅡb polymorphism and the down-regulation of FcγRⅡb protein on B cell surface in Hashimoto′s thyroiditis patients, and FcγRⅡb can be a predisposed factor for Hashimoto′s thyroiditis.

Although widely applied in treating hematopoietic malignancies, transplantation of hematopoietic stem/progenitor cells (HSPCs) is impeded by HSPC shortage. Whether circulating HSPCs (cHSPCs) in steady-state blood could be used as an alternative source remains largely elusive. Here we develop a three-dimensional culture system (3DCS) including arginine, glycine, aspartate, and a series of factors. Fourteen-day culture of peripheral blood mononuclear cells (PBMNCs) in 3DCS led to 125- and 70-fold increase of the frequency and number of CD34⁺ cells. Further, 3DCS-expanded cHSPCs exhibited the similar reconstitution rate compared to CD34⁺ HSPCs in bone marrow. Mechanistically, 3DCS fabricated an immunomodulatory niche, secreting cytokines as TNF to support cHSPC survival and proliferation. Finally, 3DCS could also promote the expansion of cHSPCs in patients who failed in HSPC mobilization. Our 3DCS successfully expands rare cHSPCs, providing an alternative source for the HSPC therapy, particularly for the patients/donors who have failed in HSPC mobilization.
