Type 2 diabetes mellitus (T2DM) is a common chronic disease characterized by hyperglycemia. Itchy skin is common in patients with diabetes, and high blood sugar leads to decreased immunity and nerve damage, causing skin problems. 40 patients with T2DM complicated with pruritus diagnosed and treated in our hospital from March 2022 to September 2022 were included to observe the clinical characteristics of the patients.

【Objective】 To explore the efficacy of Mathieu combined with tongue-shaped flap covering in children with distal hypospadias and micropenis head deformity. 【Methods】 The clinical data of 72 patients with distal hypospadias complicated with micropenis treated during Jan.2018 and Jun.2021 were retrospectively analyzed, including 35 patients who underwent modified Mathieu combined with tongue-shaped flap and external urethral orificium (study group), and 37 patients who underwent traditional Mathieu (control group). Urethral stricture, urethral fistula, urethral diverticulum and penile head cleft were compared between the two groups. 【Results】 Urinary fistula occurred in 2 cases (5.27%) and 9 cases (24.32%) in the study group and control group, respectively, the incidence being much lower in the study group (P=0.028). Urethral stricture occurred in 1 case (2.86%) and 1 case (2.70%) in the study group and control group, respectively; penile head dehiscence in 1 case (2.86%) and 3 cases (8.11%); urethral diverticulum in 0 case (0%) and 2 cases (5.41%). There were no significant differences between the two groups in the incidence of urethral stricture, urethral dehiscence and urethral diverticulum (P>0.05). 【Conclusion】 Mathieu combined with tongue-shaped flap covering to treat children with distal hypospadias with micropenis head deformity can reduce the incidence of postoperative complications, achieve high surgical satisfaction and appearance satisfaction in the first phase, reduce harm caused by surgery, and promote patients’ psychological health.

BACKGROUND:Neuroblastoma is the most common solid tumor in infants and children. Targeting cancer stem cel therapy can be expected to cure cancer radicaly, but because of smal number, anti-apoptotic and anti-chemotherapy capacity, cancer stem cels are not sensitive to the radiotherapy and chemotherapy. OBJECTIVE:To explore the expression of stem cel marker CD133 in neuroblastoma and its clinical significance. METHODS:Fifty-eight children with neuroblastoma admitted at Department of Pediatric Surgery, the First Affiliated Hospital of Xinjiang Medical University, China from June 2004 to February 2014 were enroled, including 46 cases of neuroblastoma and 12 cases of ganglion neuroblastoma. Then, the expression level of CD133 was analyzed by immunohistochemistry method, and the relationship between pathological types, International Neuroblastoma Staging System stage, survival time after surgery and the expression level of CD133 was explored. RESULTS AND CONCLUSION:There were 22 cases (48%) of neuroblastoma positive for CD133, and 4 cases (33%) of ganglion neuroblastoma positive for CD133. CD133 mainly expressed in the tumor cel cytoplasm. The expression rates of CD133 in different clinical stages were significantly different (P=0.011), which were 21% for stages 1 and 2, 64% for stages 3 and 4, 36% for stage 4S. And the positive rates of CD133 between patients with good prognosis and patients with poor prognosis were significantly different (P=0.031), which were 29% and 57%, respectively. The life cycle of CD133-negative patients was significantly longer than that of CD133-positive infants (P < 0.05). There were tightly connections between CD133 and the occurrence, development, and prognosis of neuroblastoma, and thus, CD133 is of great significance to assess the survival time after surgery and improve of the diagnosis and treatment of neuroblastoma.

ObjectiveTo monitor the early blood lactic acid concentration of patients with severe trauma who have been experienced routine surgery or damage control surgery,and explore the influence of surgical methods for the early lactate clearance rate.MethodsSelected 40 patients with severe trauma,they were divided into two groups with 20 cases each in accordance with the adopted operation mode,reference group by damage control surgery,and control group by routine surgery.Recorded acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ ) in patients after admission,blood lactic acid concentration at 6 h after admission and admission,calculated the early lactate clearance rate.ResultsIn reference group,blood lactic acid concentration at 6 h after admission was significantly lower than that in control group[ (3.5 ± 1.1 )mmol/L vs.(4.2 ± 1.4) mmol/L,P< 0.05 ],early lactate clearance rate was higher than that in control group [ (24.6 ± 6.3 )% vs.( 11.4 ± 5.3 )%,P< 0.05 ].Conclusions Damage control surgery in patients with severe trauma in favour of the early removal of lactic acid,maintaining the homeostasis of the organism,is the key to improve the achievement ratio of treatment with severe trauma.

Nondegradable stent graft and drug-eluting stent inhibit intima hyperplasy to certain extent, reduce the incidence of restenosis, and probabilize the treatment of coronary artery disease. However, the stent is a metallic foreign body, so it can induce thrombogenesis or immune responses. Novel biodegradable stent has good biocompatibility and biodegradation. It can degrade into CO2 and H2O2, participate metabolism, with no toxicity or complication caused by permanent metal stent. However, the biodegradable stent possesses inadequate mechanical performance and support. How to improve the biological stability and controllability through optimizing material integral quality and modulating their molecular constitution, and how to reduce inflammatory reaction and vascular restenosis after stenting are the study focuses in medical and material fields.
