Objective To investigate the technical feasibility and clinical significance of non-vascular contrast-enhanced ultrasound(NVCEUS) in screening pyelogenie cyst out of simple renal cysts so as to avoid damage to the urinary tract from absolute ethanol while undergoing percutaneous aspiration and ethanol sclerotherapy(PAEST). Methods Following an inclusion criteria 23 patients with renal cysts were selected to receive NVCEUS scanning by means of administrating SonoVue contrast agents through puncture needle into their renal cyst lumen prior to the injection of absolute ethanol for sclerosing treatment. By the demonstration of hyperechoic contrast agents leaving from intra cyst into renal collecting system,a pyelogenic cyst was defined. The patients with this kind of cyst was not allowed for further ethanol sclerotherapy. Results NVCEUS made 3 patients with pyelogenic cyst resembling simple ones free from ethanol selerotherapy,and 4 patients suspicious of pyelogenic cyst due to weird cyst configuration remain in the list of simple cyst for further selerotherapy. Conclusions NVCEUS of renal cyst is highly capable of differentiating pyelogenie cyst from simple cyst and highly valuable in increasing the safety for the procedure of PAEST.

Objective To establish a treatment proposal of thyroid adenoma by using percutaneous radiofrequency ablation(RFA) and investigate its techniques and skills, means and steps, and safety and efficacy. Methods Contrast-enhanced ultrasound-guided percutaneous RFA of thyroid adenomas were conducted on 202 patients by using an auto-controlled bi-polar electrode system. The indications of thyroid RFA,the optimal puncture route,the ways of anesthesia administration, protection of vital neck vessels and recurrent laryngeal nerve(RLN) and reduction of bleeding from core biopsy, indicators of ending ablation procedure following a complete ablation were investigated and analyzed. Resalts An adenoma smaller than 20 mm in maximal diameter was the optimal candidate for RFA. Either of two puncture routes could be selected upon the target lesion's location. Areas surrounding to the thyroid capsule needed adequate local anesthesia to kill pain. Liquid-isolating maneuver could effectively protect carotid artery and RLN from core needle cutting and electrode heating injury. Advanced block of supplying arteries with heating markedly reduced bleeding involved in the biopsy. Multipoint and multicenter ablation was essential to a complete coagulation. Filling-defect in the ablated adenoma on CEUS was the key sign to terminate ablation procedure. Conclusions Percutaneous bi-polar RFA was proved feasible, effective, safe and supermicroinvasive for treating thyroid adenoma under the way stated here of puncture and technical points and use of CEUS for monitoring.

Objective:To observe the clinical efficacy and adverse reactions of rituximab in the treatment of systemic sclerosis (SSc).Methods:Eight SSc patients who received rituximab treatment in the Department of Rheumatology of Shanghai Ruijin Hospital from November 2016 to May 2020 were treated with rituximab at week 0, week 2, week 4, week 24 and week 48. The clinical symptoms and laboratory parameters were evaluated at baseline, week 4, week 24 and week 48 respectively. All data were analyzed by Wilcoxon test.Results:All the patients were diagnosed as diffuse SSc, including seven females and one male, with a median disease course of 2.5 years. At week 0, week 24 and week 48, the modified Rodnon skin scores (MRss) were 16.5 (11.8, 29.5) , 14.5 (9.5, 27) ( Z=0.841) and 10.5 (7, 24.3) ( Z=0.420) respectively, which were significantly improved as compared with the baseline ( P<0.05). The patients' self-scores were 60(50, 77.5), 52.5(41.3, 67.5)( Z=0.113) and 47.5(36.3, 57.5)( Z=0.474) respectively, which were significantly improved at week 24 and week 48, and the High Resolution CT (HRCT) scores at baseline and week 48 were 2.7(1.02, 3.7) and 1.6(0.65, 2.95)( Z=0.964) respectively, significantly improved after treatment ( P<0.05). The pulmonary aterial hypertension (PAH) values were 48(41, 58.5) mmHg and 47(38.5, 57) mmHg ( Z=0.315) respectively. There was no significant difference between the two groups. Clinical observation showed that the condition was improved and no adverse reaction occurred at the same time period. Conclusion:The improvement of skin sclerosis, pulmonary interstitial lesion and pulmonary artery pressure can be observed during the treatment with rituximab, which may be a new choice for the treatment of SSc. There is no serious adverse reaction during the treatment, and the patients are well tolerated and safe.

Objective To analyze the outcomes and the prognostic factors of hematopoietic stem cell transplantation (HSCT) in combination with imatinib for Philadelphia chromosome positive acute lymphoblastic leukemia (Ph+ ALL). Methods All 32 patients with Ph+ ALL achieved hematologic complete remission (CR) at time of transplantation, including 27 cases in the first CR (CR1) and 5 in CR2. Nineteen patients achieved molecular remission (MR). Among 32 patients, 4 received autologous HSCT (AHSCT), and 28 allogeneic HSCT (allo-HSCT). The conditioning regimens comprised of total body irradiation (TBI), cyclophosphamide, fludarabine and cytarabine. The median number of transfused mononuclear cells was 5. 6 × 108/kg, and that of CD34+ cells was 2. 94 × 106 /kg. Thirty-one patients were administrated imatinib orally before transplantion, at a dose of 400~600 mg/day, and 16 patients after transplantation, including 7 for prevention at a dose of 300~400 mg/day and 9 for salvage treatment at a dose of 400 ~ 600 mg/day. Results Hematopoietic reconstitution was achieved in all 32 patients. Three-year estimate of overall survival (OS) was (62. 1±8. 6)%, leukemia-free survival (LFS) (59. 2 ± 8. 7)%, relapse rate (RR) (17. 7 ± 7. 2)% and transplant-related mortality (26. 2 ± 8. 0) %. All 4 undergoing AHSCT were alive, and 3 out of them were in continuous CR with durations of 14, 18 and 67 months respectively. The univariate analysis for prognosis in allo-HSCT showed that the OS of HLA-matched sibling donors group was 76. 5 %,higher than that of unrelated or haploidentical donors group (27. 3 %, P<0. 05), and so was LFS (70. 6 % vs 27. 3 %, P<0. 05). RR in patients achieving MR at time of transplantation was 5. 6 %,lower than that in those not achieving MR (40. 0 %, P<0. 05). RR in patients in CR1 at time of transplantation was 12. 5 %, lower than that in those in CR2 (50 %, P <0. 05). Conclusion Imatinib improved the outcomes of HSCT for Ph+ ALL, especially to patients achieving MR at time of transplantation and transplantation in early stage (CR1).

OBJECTIVETo investigate the prevalence of esophageal and gastric cardia cancer and various precancerous lesions in high-risk rural areas.
METHODSRandom cluster sampling method was used to select people aged 40-69 years of some natural villages as screening objects in Feicheng, Shangdong province, from 2006 to 2012. The screening program was conducted by endoscopy with iodine staining and indicative biopsy followed by pathological examination.
RESULTSA total of 24 759 subjects were screened during 2006-2012 years. The positive detection rates of esophagus and gastric cardia cancers were 1.37% and 0.42%, respectively, the early diagnosis rates were 84.71% and 65.05%, and the treatment rates were 92.65% and 92.23%, respectively. The detection rates of all lesions in males were significantly higher than those in females (P < 0.05), and were gradually increased with age (P < 0.05). The time trend analysis showed that detection rates of all lesions in the two sites showed no significant changes during this period, and the detection rates of esophageal lesions were higher than those of gastric cardia.
CONCLUSIONSThere are considerable numbers of patients with precancerous lesions in the general population from the high risk areas. Men and the elderly are the key populations calling for cancer control programs. Endoscopy using iodine staining is an effective method to increase the detection rate of precancerous lesions and cancers. The root of mucosal fold in gastric cardia must be carefully observed so as to increase the detection rate of early gastric cardia lesions.

Objective To investigate the impacts on inpatient costs of a hospital in Beijing as incurred by the reform of clinic-pharmacy-separation by means of DRGs. Methods As required by BJ-DRGs, we selected DRGs grouping information and medical record homepage information of the inpatients discharged from a tertiary hospital in Beijing from January to March in 2017 ( pre-reform group ) and that from May to July in 2017 ( the post-reform group ) . Then we compared the differences of inpatient costs before and after the reform, and the inpatient cost changes of the DRGs groups. Results The median of inpatient costs before the reform was 8751. 21 yuan, and that after the reform was 8522. 07 yuan, a difference without statistical significance (P>0. 05). Of the 104 DRGs studied, cost changes were found in 28 DRGs (P<0. 05), with increases in 19 DRGs and drops in 9 DRGs groups. Conclusions The reform, though without impact on the inpatient costs, changed the makeup of costs on the other hand, especially on HJ13 and BB25 DRGs groups, worthy of attention. A dynamic tuning mechanism is thus suggested for pricing of medical services, and a fine management suggested for the hospitals to curb unreasonable growth of costs.
