Arthroscopic Intra‐Articular Repair of the Torn Subscapularis Tendon with Single Anterior Portal,Single Suture Anchor,and X‐Shaped Fixation Technique

Subscapular tendon plays an important role in shoulder joint function. With the advance of magnetic resonance imaging technology and the popularization of arthroscopic shoulder surgery, subscapularis tears have been increasingly detected. However, reduction and fixation of subscapular tendon tears appears to be technically challenging. This study aims to describe an arthroscopic intra‐articular X‐shaped fixation technique: a procedure of subscapularis tendon repair performed with the aid of a suture passer using only a single anterior portal and a single suture anchor. By incorporating the advantages of a single anterior working portal for anchor placement and tear repair, this technique provides an easier way to use suture lasso and make knots in a limited working space, and the whole procedure is minimally invasive with a short learning curve. This technique has been applied in patients with subscapularis tears involving no intraoperative or postoperative complications. Our technology offers a valuable new treatment option for subscapularis tears.     

被覆自体微粒皮的辐照氟银猪皮移植治疗深度烧伤15例报告

OBJECTIVE: To study the feasibility of using irradiated porcine skin impregnated with fluorine and silver covered by autogenous skin granule graft in the treatment of severe burn injury. METHODS: Autogenous split-thick skin grafts were cut into small pieces (<1 mm3), which were transferred onto the sheet of porcine skin mounted with a layer of Xinnaxing ointment (2 mm in thickness). After eschar removal, the burn wound was covered with the prepared porcine skin, sutured and fixed with small holes at the lower site for drainage. The growth of autogenous granule skin was then observed and the criteria for therapeutic effect evaluation drafted. RESULTS: The layer of Xinnaxing ointment on the the porcine skin improved the adhesion of the autogenous small skin grafts, therefore full use could be made of the donor skin source. In the 15 patients receiving this treatment, the graft-covered area was (12.3+/-3.5) % that of the wound, with the donor-recipient area ratio of 1: (11.0+/-2.7) and subsequent healing time of 27.5+/-5.5 d. Primary healing was achieved in 9 cases, and secondary healing in 6, demonstrating similar clinical effect to that of allo-skin grafting. CONCLUSION: The method is easy and economic, which saves autogenous skin source and produces satisfactory clinical effect.

Pan‐risk factor for a comprehensive cardiovascular health management

Cardiovascular diseases (CVDs) have become the leading cause of death in China. CVDs are mainly caused by multiple well‐known modifiable risk factors that are affected by socioeconomic and environmental determinants, lifestyle and behavioral choices, and familial and genetic predispositions. With more risk factors proved to be associated with CVD occurrence, the concept “pan‐risk factor” is proposed in this review to indicate all discovered and yet‐to‐be‐discovered CVD risk factors for comprehensive primary prevention of CVD. Recognizing more factors and their roles in CVD development and progression is the first step in reducing the ever‐increasing burden of CVD. This review is an overview of the pan‐risk factor whose associations with CVD outcomes have been established. Along with the accumulation of scientific evidence, an increasing number of risk factors will be discovered and included in the list of pan‐risk factors.     

Does Waldenstrom’s macroglobulinemia also cause bone destruction? A rare case report

Waldenstrom’s macroglobulinemia (WM) is a rare type of malignant B-cell lymphoma. The main feature of WM is elevated serum monoclonal immunoglobulin M, similar to multiple myeloma (MM). Unlike in MM, the rarity of destructive bone lesions in WM has been repeatedly emphasized. We report a unique case of WM with a vertebral compression fracture as the first symptom. This case highlights that the presence or absence of bone destruction may not clearly distinguish between WM and MM. The possibility of WM should be considered in patients with vertebral fracture and destruction as the first presentation. Performing vertebral bone marrow aspiration biopsy during percutaneous vertebroplasty is a convenient and effective method to assist in the diagnosis of WM.

奥曲肽治疗原发性肝癌临床疗效和生活质量的评价

目的 评价生长抑素类似物奥曲肽(OCT)对原发性肝癌的治疗效果及对患者的生活质量的影响.方法 62例原发性肝癌患者根据患者意愿分为奥曲肽治疗组(30例)和对照组(32例),分别采用奥曲肽联合对症支持治疗及单纯对症支持治疗,在治疗后3个月及6个月对患者的疗效及生活质量进行评定.结果 (1)治疗组患者平均牛存期为(12.89±6.21)个月较对照组患者(5.36±6.36)个月明显延长(t=4.712,P<0.01),治疗组患者6个月和12个月的累积生存率(73.3%、50.0%)与对照组(40.6%、9.37%)比较有明显提高(χ2=4.02,)(χ2=9.67,均P<0.05).(2)奥曲肽治疗后21例患者食欲改善,12例患者体重增加,17例患者乏力状况好转,对照组在上述方面无明显改善.(3)治疗6个月时对照组中复杳CT肿块继续增大8例,其中发生肝外转移6例.治疗组中18例复查CT示:肝癌肿块缩小6例;无明显变化9例;肿块较前增大3例,其中发生肝外转移1例.(4)应用奥曲肽治疗初期有轻度腹泻者6例,继续用药1个月症状消失. 结论生长抑素类似物奥曲肽治疗原发性肝癌患者的平均生存期明显延长、6个月和12个月的累积生存率明显提高,药物耐受性好,可以提高原发性肝癌患者的牛活质量.
