OBJECTIVETo investigate the clinical characteristics, diagnosis, treatment and prognosis of deep sarcoma of the penis.

METHODSThe pathological and clinical data of 2 cases of deep sarcoma of the penis were analyzed retrospectively and the literature reviewed.

RESULTSBoth of the cases were treated by total penectomy. Epithelioid angiosarcoma of the penis was confirmed by postoperative pathology in one patient, who died of pulmonary metastasis in the eighth month after the operation; and epithelioid sarcoma of the penis was confirmed in the other, who died of brain metastasis in the second month after the operation.

CONCLUSIONDeep sarcoma of the penis is rare but can be diagnosed pathologically. Total penectomy is the main option for its treatment. Node dissection, with poor prognosis, is not recommended unless adenopathy is palpable.

OBJECTIVETo observe the efficacy and safety of oral propranolol in the treatment of periorbital proliferating phase infantile hemangioma.

METHODSA retrospective review of patient medical records was performed. 12 patients (9 female, 3 male; 1.5-8.5 months, average 3.3 months) with periorbital proliferating phase infantile hemangioma underwent oral propranolol therapy. The dosage was slowly increased to 2 mg/kg daily in divided doses for a mean duration of 16 weeks (range 4 weeks-41 weeks). Therapeutic outcomes and safety were established by evaluating colour, size of lesion, duration of treatment and side-effects of treatment before and after treatment.

RESULTSOf these, 9 had a signification reduction in colour and size of the lesions, 2 had no further growth. 1 is stopped therapy due to hypotension after drug administration. 11 other patients, although mild adverse effects were noted, no symptoms were severe enough to discontinue treatment.

CONCLUSIONSPropranolol appears to be a safe and effective treatment in the management of periorbital proliferating phase infantile hemangioma.

OBJECTIVETo evaluate the clinical results of tube gastrostomy in radical cystectomy and ileal conduit.

METHODSWe retrospectively analyzed the data of 98 patients undergoing radical cystectomy and ileal conduit between March 2007 and February 2010. According to postoperative gastrointestinal decompression methods, the patients were divided into nasogastric decompression group (n=50) and tube gastrostomy group (n=48), and the gastrointestinal recovery time, surgical complications and hospital stay were compared between them.

RESULTSNo statistical difference was found in gastrointestinal recovery time, hospital stay, or surgical complications between the two groups, but the incidence of pulmonary infection was significantly lower in tube gastrostomy group than in nasogastric decompression group (P<0.05).

CONCLUSIONTube gastrostomy is an easy, safe and effective means for gastric decompression after radical cystectomy with ileal conduit, especially suitable for elderly patients and those with potential pulmonary disorder.

OBJECTIVETo evaluate the efficacy and safety of olmesartan medoxomil compared with losartan potassium in patients with mild to moderate essential hypertension.

METHODThis is a randomized, double-blind, double-dummy, active-controlled, parallel, multi-center study. After a 2-week placebo run-in period, a total of 287 eligible subjects were randomized at 1:1 ratio to receive olmesartan medoxomil 20 mg or losartan potassium 50 mg, once daily for 8 weeks. The blood pressure was assessed after 4 weeks treatment. If the subject's seating diastolic blood pressure (SeDBP) was still >or=90 mm Hg, the dosage was doubled for another 4 weeks; for those subjects whose SeDBP was <90 mm Hg after 4-week treatment, the initial dosage remained unchanged and the treatment continued until completion of the study.

RESULTS(1) The mean trough reduction in SeDBP from baseline in olmesartan group was significantly greater than that in losartan group after 4 weeks (11.72 mm Hg vs 9.23 mm Hg, P=0.004) and 8 weeks treatment (12.94 mm Hg vs 11.01 mm Hg, P=0.035). (2) The number and percentage of responders in olmesartan group (81, 65.3%) were statistically higher than those (68, 52.7%) in losartan group (P=0.028) after 4 weeks treatment and were similar between the two groups after 8 weeks treatment (P>0.05). (3) Individual and overall trough/peak ratios of DBP and SBP in 24-hour ambulatory blood pressure monitoring were higher in olmesartan group than losartan group. The hypotensive effect of olmesartan was more durable than losartan at 24 hour interval. (4) The incidence of study drug-related adverse events (AEs) in olmesartan group (10.5%) was similar as that in losartan group (13.9%, P>0.05). Most of these AEs were mild and transient.

CONCLUSIONThis study shows that olmesartan medoxomil, at oral dose of 20 mg-40 mg once daily was effective and safe for hypertension treatment and the hypotensive effect was superior to losartan potassium (50 mg-100 mg once daily).

Objective:To explore the value of 5G-based robotic remote ultrasound diagnosis system in musculoskeletal joint injuries.Methods:From March to December 2020, 58 volunteers at a training base who felt musculoskeletal pain or paresthesia were selected and performed both robotic remote ultrasound (remote ultrasound group) and conventional ultrasound (portable ultrasound group). The two types of examinations were compared, the consistency of the two diagnosis results was analyzed by the Kappa test, and the the difference of the diagnosis results was compared by McNemar test.Results:Among the 58 volunteers, 40 cases were positive by both methods and 11 volunteers had 2-3 positive results. There were 59 positive results in the remote ultrasound group and 64 positive results in the portable ultrasound group. The positive rate of the examination sites from high to low was knee joint>foot and ankle joint >hand and wrist joint >shoulder joint>elbow joint, calf and hip. The diagnosis results of the two groups were in good consistency (Kappa=0.782, P<0.001), and there was no statistically significant difference in the diagnosis results between the two groups (χ 2=3.2, P=0.063). Five more diseases with positive results were detected in the portable ultrasound group: 1 meniscus injury, 1 medial collateral ligament injury, 1 soft tissue injury around the metatarsal, 1 biceps tendinitis with effusion and 1 cubital ulnar nerve subluxation. Conclusions:The 5G-based robotic remote ultrasound system has good consistency with conventional ultrasound in the diagnosis of musculoskeletal injures. It can be applied to the ultrasound diagnosis of musculoskeletal joint injuries in remote areas.

The identification and use of molecular biomarkers have greatly improved the diagnosis and treatment of malignant tumors. However, a much deeper understanding of oncogenic proteins is needed for the benefit to cancer patients. The lipid raft marker proteins, flotillin-1 and flotillin-2, were first found in goldfish retinal ganglion cells during axon regeneration. They have since been found in a variety of cells, mainly on the inner surface of cell membranes, and not only act as a skeleton to provide a platform for protein-protein interactions, but also are involved in signal transduction, nerve regeneration, endocytosis, and lymphocyte activation. Previous studies have shown that flotillins are closely associated with tumor development, invasion, and metastasis. In this article, we review the functions of flotillins in relevant cell processes, their underlying mechanisms of action in a variety of tumors, and their potential applications to tumor molecular diagnosis and targeted therapy.
