BACKGROUND:Acromion morphology is the most important external factor of degenerative rotator cuff tear,and studies on acromion morphology and acromion coverage have been continuing. OBJECTIVE:To investigate the coverage of acromion on rotator cuff tissue in three-dimensional space,measure coronal and sagittal parameters,and explore the relationship of acromial overhang,acromioglenoid angle and acromial coverage angle with degenerative full-thickness rotator cuff tears. METHODS:A total of 56 patients diagnosed with full-thickness rotator cuff tears by shoulder arthroscopic surgery or MRI in the Affiliated Hospital of Xuzhou Medical University from January 2022 to June 2023 were retrospectively collected as the tear group,while 48 patients with non-rotator cuff tear were included as the control group.Clinical data and chest CT data of the patients of the two groups were collected,and the shoulder blades of the patients were reconstructed using Mimics software.Acromial overhang,acromioglenoid angle and acromial coverage angle were measured in 3-matic software.The differences between the measurement parameters were compared between the two groups.Binary Logistic regression analysis and receiver operating characteristic curve analysis were performed to evaluate the ability of the measurement parameters to predict rotator cuff tear.It is generally believed that the parameter had good diagnostic value when the area under the receiver operating characteristic curve was greater than 0.8. RESULTS AND CONCLUSION:(1)The mean acromial overhang in patients with rotator cuff tears was greater than that in controls(P<0.001).The mean acromial coverage angle was also greater in patients with rotator cuff tears than in controls(P<0.001).There was no significant difference in the acromioglenoid angle between the two groups(P>0.05).(2)Binary Logistic regression analysis showed that acromial overhang and acromial coverage angle were both risk factors for rotator cuff tear(P<0.05).(3)Receiver operating characteristic curve analysis indicated that the areas under the curve of acromial overhang and acromial coverage angle were 0.725 and 0.865,respectively,and the optimal cutoff values were 36.15 mm and 60.65°.(4)The results showed that the acromial overhang and acromial coverage angle were greater in patients with rotator cuff tears than in patients without rotator cuff tears.Both were associated with degenerative full-thickness rotator cuff tears,and they could be used to predict rotator cuff tears,and the acromial coverage angle was more effective in predicting rotator cuff tears.

Objective To conduct a systematic search for qualitative studies that explore the experience and needs of risk communication in the pathogenesis of cardiovascular diseases,so as to provide references for risk communication strategies of cardiovascular diseases.Methods Qualitative studies on the experience and needs of cardiovascular disease risk communication among high-risk groups in relevant domestic and foreign databases were retrieved from database inception inception to October 2023.Results A total of 10 studies were included,and 33 findings were collected.Similar results were grouped into 10 new categories,and these categories were integrated into 4 synthesis results,including benefits of risk communication,attitude towards risk communication emotional response caused by risk communication,demand and expectation for risk communication.Conclusion Risk communication is an important premise of strengthening primary prevention for cardiovascular diseases.The effect of risk communication has been affirmed by most patients with risk factors,but there are still shortcomings.In the future,we should continuously optimize risk assessment tools,improve the content,form and timing of risk communication,strengthen the construction of risk communication teams,provide social support,and improve the effect of risk communication.

The applications are narrow in the scope of conventional ultrasound-guided lung biopsy due to the restriction of techniques.With the development and application of new ultrasonic techniques,a number of novel ultrasound-guided methods are applied in lung biopsy,which not only improv the accuracy of diagnosis,but also extend to special locations where conventional methods are difficult to obtain samples.The application of new ultrasonic technology in lung biopsy were reviewed in this article.

Objective To summarize our experience with surgical management of renal neoplasm involving inferoir veno cava.Methods We review the data of 115 patients,including 74 male patients and 41 female patients,with renal neoplasm involving venous system between March 1993 and December 2015.The mean age was 52 years old,ranging 22 to 77 years old.The tumor was found in right side in 77 cases and left side in 38 cases.There were 15 patients (13.0％) with renal vein thrombus,38 (33.1％) with infrahepatic thrombus,29 (25.2％) with low retrohepatic thrombus,20 (17.4％) with high retrohepatic thrombus,and 13 (11.3％) with supradiaphragmatic thrombus.The mean age was 52 years old,ranging 22 to 77 years old.The tumor was found in right side in 77 cases and left side in 38 cases.All patients accepted the radical nephrectomy.Primary outcomes were overall survival (OS),and cancer special survival (CSS) in patients with renal cell carcinoma (RCC) estimated by Kaplan-Meier method.Secondary outcome included operative and oncological features,past-operative complications and hospital mortality.Cox proportional hazard model was used to univariate and multivariate analysis for risk factor impacting on OS of RCC patients.Results Complete resections of renal neoplasm with tumor thrombus were achieved in 113 patients (98.3％),2 patients died intraoperatively due to the dropping of thrombus.Postoperative complication rate was 16.8％.Hospital mortality was 2.6％.Mean follow-up interval was 48 months.OS rates at 5-,and 10-year in RCC patients were 66.5％,and 61.8％,respectively.Metastasis was an independent risk factor affecting on OS (P =0.000).However,the level of thrombus was not an risk factor affecting the prognosis.Conclusions Radical resection of renal tumor and caval thrombus is an effective treatment for prolonging survival in patients with RCC extending into venous system.Retrohepatic caval tumor thrombus below or above the main hepatic vein should be dichotomized and managed respectively with diverse techniques.Metastatic rather than the level of thrombus was a risk factor impacting on RCC patient survival.

Objective To clone and express a high mobility group box 1(HMGB1)protein of Schistosoma japonicum(Main-land strain)and analyze its function. Methods The DNA fragment of open reading frame encoding Sj HMGB1 protein was ampli-fied by RT-PCR from the mRNA of S. japonicum worms,then it was subcloned into the expression vector pET28a(+)to form the recombinant expression plasmid SjHMGB1-pET28a. The recombinant expression plasmid was transformed into the component E. coli BL21(DE3),and the tranformant containing recombinant expression plasmid was induced with IPTG to express the recombi-nant protein SjHMGB1. The recombinant SjHMGB1 protein was purified by affinity chromatography with nickel chelating affinity chromatography agarose gel. The Gel retard experiment and animal immunization were performed to analyze the DNA binding ca- pacity and the immunologic property of recombinant SjHMGB1. The expression levels of HMGB1 in different life cycle stages of S. japonicum were analyzed by Western bloting and RT-PCR. Female ICR mice were immunized with the recombinant SjHMGB1 pro-tein and infected with 45±2 cercariae of S. japonicum after three immunizations. Forty-two days post-infection,the worms and eggs of S. japonicum were recovered from the portal vein and liver tissue,respectively. The worm and egg reduction rates were calculat-ed respectively. Results A 530 bp of specific DNA fragment was amplified from mRNA of S. japonicum by RT-PCR,which was the open reading frame(ORF)encoding SjHMGB1protein confirmed by DNA sequencing analysis. The recombinant expression plasmid SjHMGB1-pET28a was constructed by cloning the ORF of SjHMGB1 into a expression vector pET28a(+). The bacterium transformants containing the recombinant plasmid expressed a soluble recombinant protein about 28 kDa after induced by IPTG, and the recombinant SjHMGB1 protein was purified by nickel chelating affinity chromatography. The gel retard experiment showed that the recombinant SjHMGB1 protein could bind to both supercoiled DNA and linear DNA,and the recombinant protein immu-nized mice produced high titers of antiserum IgG. Western bloting indicated that the recombinant SjHMGB1 protein was recognized specifically by the S. japonicum-infected mice serum. Above results showed that the recombinant SjHMGB1 protein possessed both functional activity and immunogenicity as the natural protein. RT-PCR and Western blot results showed that SjHMGB1 was abun-dantly expressed in the adult and egg stages whereas barely detectable in the cercaria stage. The immune protection experiment showed that the recombinant SjHMGB1 induced mice to produce high titers of specific antibody IgG but failed to conduct an effec-tive immune protection against S. japonicum. Conclusion The gene encoding HMGB1 from S. japonicum and the soluble recombi-nant SjHMGB1 protein with natural functional activity are obtained,and the recombinant SjHMGB1 has a high immunogenicity but is not able to induce an effective immune protection against S. japonicum.

Objective To evaluate the efficacy and safety of sunitinib as post-operative adjuvant therapy in patients with high-risk renal cell carcinoma (RCC).Methods A total of 60 patients with resected,histologically confirmed clear cell RCC were enrolled in this study.Patients received orally sunitinib either at a dose of 50 mg on treatment schedule (once daily for 4 weeks followed by 2 weeks off) or at a dose of 37.5 mg once daily for three 6-week cycles from 1 month after surgery.Results All the 60 patients tolerated Sunitinib treatment well and no patient discontinued treatment due to adverse events.Most adverse events were grade Ⅰ to Ⅱ.The most frequently reported adverse events were neutropenia (56.7％),thrombocytopenia (53.3％),leucopenia (48.3％),hand-foot syndrome (46.7％) and hypertension (36.7％).The most frequently reported grade 3 or 4 toxicities were thrombocytopenia (25.0％),neutropenia (15.0％),hand-foot syndrome (11.7％) and leucopenia (8.3％).The majority of adverse events occurred within the first 1-2 cycles of sunitinib treatment,and was ameliorated 1 month after 3 cycles finished.No irreversible adverse event was observed.As of April 5,2012,no recurrence occurred in patients except one death due to cerebrovascular accident unrelated to treatment,with both 6-month and 9-month disease-free survival rate of 100％.Conclusions Myelosuppression occurred less frequently in high-risk RCC patients treated with sunitinib as operative adjuvant therapy than in advanced RCC patients,with a better benefit trend.However,long-term follow-up data are needed to further confirm the efficacy of sunitinib in the adjuvant setting.

Objective To investigate the therapeutic effects, safety of ureteral calculus accom panied with granulation treated with pneumatic lithotripsy and two-macron laser via transurethral uret eroscopic. Methods From June 2007 to March 2010, 38 cases of ureteral calculus accompanied with granulation were treated with 2 μm laser and pneumatic lithotripsy via ureteroscope. All the patients had middle to severe hydronephrosis. The granulation under the calculus was vaporized with the 2 μm laser, and then the ureteral stone was fragmented with pneumatic lithotripsy. The clinical datum,stone disintegration rate, lithagogue rate and complication were retrospectively analyzed. Results Among 38 cases of ureteral stones, rate of successful fragmentation in a single procedure was 92%(35/38). The operation time ranged from 15 to 45 min, mean (23.0±6.5)min. Estimated the intraoperative blood loss was (7.0±4.5)ml. The postoperative hospitalization time was (5.2±0.6)d. Two upper ureteral stones were pushed back to the renal pelvis and a conversion to extracorporeal shock wave lithotripsy (ESWL) was needed. The insertion of the ureteroscope was failed in 1 case who was accepted open operation finally. Among the 37 cases treated via ureteroscopy, stone clearance rate was about 86% after operation 1 month. Follow-up examinations for 3-15 months (mean 8 months)showed no ureteral stenosis or urinary infection. Conclusion 2 μm laser and pneumatic lithotripsyvia ureteroscope could be a highly effective and safe therapy for treatment of ureteral stone with granulation.

ObjectiveTo investigate the therapeutic effects, safety of pneumatic lithotripsy and 2 μm laser via transurethral ureteroscope for ureteral calculi accompanied with granulation. Methods27 cases (30 sides) of ureteral calculi accompanied with granulation treated with 2 μm laser and pneumatic lithotripsy via ureteroscope were reviewed. Results28 sides were fragmented successfully in a single procedure. The operation time was 15～45 min (mean 25 min). The intraoperative blood loss was 3～15 ml (mean 5 ml). The postoperative hospitalization time was 3～7 d (mean 5.5 d). 1 upper ureteral stone was pushed back to the renal pelvis and extracorporeal shock wave lithotripsy was needed. The insertion of the ureteroscope was failed in 1 cases, who accepted open operation finally. Double-J tubes were pulled out in all the patients after 1 month, and 26 sides were stone-free. They were followed-up for 3～15 months (mean 8 months), no ureteral stenosis or urinary infection was found. Conclusion2 μm laser and pneumatic lithotripsy via ureteroscope is an effective and safe therapy for ureteral calculi with granulation, especially for those on middle or lower levels.

Objective To assess the value of percutaneous balloon catheter occlusion technique for tumor thrombectomy in renal or adrenal neoplasm extending into the inferior vena cava(IVC). Methods Twelve patients with renal or adrenal neoplasm extending into retrohepatic or subhepatic IVC were diagnosed by the investigations of CT, MR1, and Doppler ultrasound. There were 7 men and 5 women with a mean age of 51 years (range, 20 to 76 years). Of these patients, 11 had renal ne-oplasm and 1 had adrenal tumor; 11 in the right and 1 in the left; 11 with retrohepatic caval thrombus (level 2a) extension and 1 with extension into the subhepatic vena cava (level 1). On the operation day, all patients had a pereutaneous preset of the balloon catheter into the IVC, at the position be-tween hepatic vein and the tip of tumor thrombus. During surgical resection, the balloon was filled via the catheter to occlude the IVC prior to vena cavotomy. Results Radical nephrectomy and resection of vena cava thrombus was successfully performed with this technique on 12 patients. There were no operative or perioperative pulmonary embolisms or deaths, no any complication. The mean postopera-tive hospital stay was 12 d (range, 9 to 15 d). Pathological investigation revealed clear cell carcinoma in 6 patients, papillary renal cell carcinoma (RCC) in 3, metastatic hepatocellular carcinoma in 1, an-gioleiomyolipoma in 1 and adrenal leiomyosarcoma in 1. The pTNM stage in 9 patients with RCC was T3b N0 M0 in 8 patients, T3b Nx M1 in I patient. The mean followup was 21±10 months (median follow-up 24 months). Four patients died of lung or liver metastasis, and the recurrence of liver cancer at 6, 9, 15, and 22 months postoperatively. Eight patients have survived for 6 to 35 months (mean 26 months). The postoperative 1-, and 3-year cancer-specific survival rates in 9 patients with RCC were 78% and 67%. Conclusions Percutaneous balloon catheter occlusion technique is a feasible, safe, and effective method for tumor thrombectomy of low retrohepatic (level 2a) or subhepatic (level 1) type in patients with renal or adrenal neoplasm extending into the IVC. Additional experience and con-tinued investigation are warranted.
