Renal cell carcinoma is one of the significant diseases endangering human health. Recent findings have shown that the human microbiome plays an important role in the occurrence and development of renal cell carcinoma, influencing its regression and treatment outcome. At present, microecological research on renal cell carcinoma are still in their initial stages, and their regulatory roles and specific mechanisms still need to be further explored. This article reviews the relationship between the human microbiome and renal cell carcinoma occurrence and development, as well as its role in diagnosis and therapies.

Cancer is the leading cause of death worldwide. Drugs play a pivotal role in cancer treatment, but the complex biological processes of cancer cells seriously limit the efficacy of various anticancer drugs. Autophagy, a self-degradative system that maintains cellular homeostasis, universally operates under normal and stress conditions in cancer cells. The roles of autophagy in cancer treatment are still controversial because both stimulation and inhibition of autophagy have been reported to enhance the effects of anticancer drugs. Thus, the important question arises as to whether we should try to strengthen or suppress autophagy during cancer therapy. Currently, autophagy can be divided into four main forms according to its different functions during cancer treatment: cytoprotective (cell survival), cytotoxic (cell death), cytostatic (growth arrest), and nonprotective (no contribution to cell death or survival). In addition, various cell death modes, such as apoptosis, necrosis, ferroptosis, senescence, and mitotic catastrophe, all contribute to the anticancer effects of drugs. The interaction between autophagy and these cell death modes is complex and can lead to anticancer drugs having different or even completely opposite effects on treatment. Therefore, it is important to understand the underlying contexts in which autophagy inhibition or activation will be beneficial or detrimental. That is, appropriate therapeutic strategies should be adopted in light of the different functions of autophagy. This review provides an overview of recent insights into the evolving relationship between autophagy and cancer treatment.

Objective To report our efficacy of one-stage definite treatment of Gustilo type Ⅲ open fractures of long bone by plate osteosynthesis.Methods A retrospective case series study was conducted of the 69 cases who had undergone plate osteosynthesis for one-stage definite treatment of Gustilo type Ⅲ open fractures of long bone from January 2006 to June 2016 at Microsurgery and War Trauma Center of Chengdu Military Command,59 Hospital of Chinese PLA.They were 47 males and 22 females with an average age of 34.2 years (from 2 to 62 years).There were 27 shaft fractures of tibia or fibula (13 cases of type ⅢA,12 cases of type Ⅲ B and 2 cases of type Ⅲ C),4 fractures of distal tibia (2 cases of type Ⅲ A and 2 cases of type ⅢB),14 shaft fractures of ulna or radius (9 cases of type ⅢA,3 cases of type ⅢB and 2 cases of type Ⅲ C),12 factures of humeral shaft (7 cases of type Ⅲ A,3 cases of type Ⅲ B and 3 cases of type Ⅲ C),3 fractures of distal humerus (all type ⅢC),6 fractures of femoral shaft (5 cases of type ⅢA and one type Ⅲ C),and 3 fractures of distal femur (2 cases of type ⅢA and one type ⅢC).The intervals between injury and operation ranged from 4 to 17 hours,averaging 9.6 hours.After thorough debridement,osteosynthesis was performed with locking compression plate,limited contact dynamic compression plate or/and reconstruction locking plate,or 1/3 tubular plate.Direct closure with decreased tension or without tension was used for type Ⅲ A injury;deep open defects were repaired with perforator flaps,neurovascular axis flaps,traditional axis flaps and muscular flaps,or local flaps;limb reconstructions included neurovascular repair in 12 cases,tendon and ligament repair in 5 cases,and muscle reconstruction in 3 cases.Superficial defects were covered by skin grafts simultaneously or secondarily.Results The duration of hospitalization averaged 19 days (from 5 to 37 days).Partial necrosis occurred in one case of sural neurovascular axis flap.Superficial infection with multiple antibiotic-resistant bacteria occurred in 2 cases.Follow-up for the 69 patients ranged from 12 to 27 months (average,19.2 months).No deep bone infection occurred.Implant breaking occurred in 4 cases and implant loosening in one.The implant failures were corrected by change into intramedullary nails or plate refixation (respectively in 2 cases) in addition to bone graft.Bone union was achieved after 5 to 15 months (average,7.7 month)with satisfactory aesthetic and functional outcomes.Conclusion For patients with Gustilo type Ⅲ open fracture of long bone,especially those with metaphyseal,intraarticular or upper limb fracture and pediatric ones,plate osteosynthesis can be a satisfactory one-stage definite treatment besides intramedullar nailing and external fixation,providing that through debridement and satisfactory soft-tissue coverage can be achieved.

Objective To explore the nursing experience of inhalation of steroid for patients after endoscopy surgery. Methods From September to December 2016, we selected 200 patients with transnasal endoscopic frontal surgery of Allergy Department at Beijing Tongren Hospital, Capital Medical University as subjects. All of the patients were treated with the inhalation of glucocorticoid. Nurses provided the guidance of inhalation of steroid for patients and observed the effects. Results A total of 200 patients accepted inhalation. After inhalation, patients' subjective symptoms improved. A total of 182 patients were very satisfied with the nursing service and 18 patients were satisfied with the nursing service. Three months after surgery, there were 152 patients without edema, 24 with the mild edema and 24 with obvious edema in operation cavity of patients. Conclusions Reasonable guidance by nurses can optimize the effects of inhalation of steroid, promote the recovery of patients after surgery and improve patient satisfaction.

Objective To investigate the clinical results of free super-thin peroneal artery perforator flap containing neurovascular axis in reconstruction of hand or foot soft tissue defects.Methods A retrospective case series study was made on 23 cases of hand or foot soft tissue defects admitted from January 2006 to March 2013.There were 16 males and 7 females,with a mean age of 33 years (range,17-51 years).Wounds were located in dorsal hand (n =12),dorsal pedis or amputated forefoot (n =8),greater thenar (n =2) and index finger (n =1) respectively.Defects ranged in size from 5.0 cm × 3.5 cm to 11.5 cm × 7.5 cm.Flap elevating was performed underneath the deep fascia and the perforator supplying the flap was dissected thoroughly,ligated and cut at the location arose from the peroneal artery.Most of the deep fascia except stripe shaped areas along the main blood supply chains was moved sharply and the fat underlying thinned primarily to the subdermal vascular network.After transferred to the recipient site,the flaps were revascularized by anastomosis of the perforating artery and its venae comitantes to appropriate recipient vessels.A total of 15 cases received innervated flap reconstruction.Flap vascularity and cosmetic results were recorded.Hand function was evaluated with the standard set up by the hand surgery branch of Chinese Medical Association.For foot reconstruction,shoe wearing status,gait,pressure-sore,flap sensibility,donor site appearance and complications were evaluated.Results All flaps were transplanted successfully with satisfactory cosmetic results,except that one flap used to cover dorsal ring finger defect left slightly bulky appearance.Mean duration of follow-up was 19 months (range,11-26 months).For hand reconstruction,the functional results were excellent in 6 cases and good in 9 cases.Repairing of foot defects with the flaps caused no problem of shoe wearing and no sore occurred.Normal gait was acquired except two cases of partially amputated foot.If innervated,flap sensibility was restored at least to the degree of S3.Protective sensation and touchpressure sensation were restored in eight non-innervated cases,and two of them were recovered to the degree of S3.There was only suture or small grafting scars on the donor leg and partially sensibility loss of lateral foot without functional defects in 13 cases.Conclusion Free super-thin peroneal artery perforator flap containing neurovascular axis is an easy and reliable technique that can attain satisfactory results for accurate coverage of hand or foot soft tissue defects.

Objective: To report operative techniques and clinical results of free sural cutaneoadipofascial flap containing the neurovascular axis based on a dominant peroneal perforating artery (DPPA, with a caliber≥0.8 mm) and its concomitant veins for reconstruction of dorsal forefoot soft tissue defects. Methods: The flap was applied in 32 cases with middle to large soft tissue defects in the dorsal forefoot from Aug. 2009 to Dec. 2014. DPPAs arising from the posterolateral intermuscular septum was located and assessed preoperatively with color Doppler flow image and computed tomography angiography. According to the location, size, and shape of the defects, one of these DPPAs was chosen for flap planning. The flap was harvested from the posterolateral aspect of the leg. The neighboring neurovascular axis (one or more of that of the sural nerve, the medial cutaneous nerve, the lateral cutaneous nerve of calf and the sural communicating nerve) was included to ensure vascular supply. According to skin laxity of the donor site, the width of the full harvesting part which should be able to cover the region of the recipient site where pressure and friction force were prominent while wearing shores was decided; the rest was harvested as an adipofascial flap (without skin) to get enough size. After transfer to recipient site, the flap was revascularized by anastomosing the perforating artery and its venae comitantes with appropriate recipient vessels, and reinnervated (antegrade or retrograded methods). Skin grafting was performed on the adipofascial surface of the flap primarily or secondarily. The defects in donor site of the leg was closed directly. Results: All flaps (ranged from 7.5 cm×5.0 cm to 23.0 cm×13.0 cm) were transplanted successfully, and no vascular or donor site problems occurred. All primary skin grafts (19 cases) was partially lost, but only 2 of them need a second grafting. Adipose necrosis occurred in 4 of 13 cases receiving secondary grafting but only needed wound care before surgery. Following up for 11-26 months showed both satisfactory functional and cosmetic results without problems of shoe wearing. Flap sensibility restored at least to the degree of S3. Conclusions The cutaneoadipofascial flap combines the advantages of perforator, neurocutaneous axis, free and adipofascial flaps leaving only suture scar in the donor leg, and is a satisfactory method for free-style and acute coverage of dorsal forefoot defects.
