OBJECTIVETo explore the therapeutic effect of radiofrequency ablation for tongue venous malformation( VM).
METHODSFrom July 2013 to July 2014, 30 cases with tongue VM (local or diffuse) were retrospectively analyzed. 23 cases underwent radiofrequency ablation treatment. The radiofrequency electrode tip(0. 5 mm in diameter) was inserted into the lesion 1 mm below the bottom with 25 W in power and 15-30 s of pulse. The treatment was repeated when the electrode tip was removed back every 1 mm. Multi-point treatment was performed.
RESULTS15 cases with unilateral VM were completely healed after one-stage radiofrequency ablation. 8 cases with bilateral VM received two-stage radiofrequency ablation with a 3-6 months of interval. Among the 8 cases, completely healing was achieved in 5 cases, partial VM residue happened in 3 cases due to its diffuse lesion and reservation of tongue function. 23 cases were followed up for 3 month to 1.5 years. Good cosmetic and functional results was achieved in 20 cases with no relapse. Partial VM residue was left in 3 cases.
CONCLUSIONSRadiofrequency ablation can effectively treat tongue VM with minimal morbidity and good cosmetic appearance. It also avoids the disadvantages of surgery.

ObjectiveTo investigate the condition of infants with urolithiasis caused by melaminetainted powdered formula at one-year follow-up. Methods Eighty-one young children with melamine-induced urolithiasis were followed up,which included urinalysis,renal-function tests,urinary tests for biochemical markers of renal glomerular and tubular function,and ultrasonography.Eighty-one age-matched healthy infants without exposure to melamine-contaminated formulas were enrolled as controls. Results Fifty-one of the patients were male and 30 female,with a mean age of 26 months (range 13 -48 months).The 81 children were divided into 2 groups according to treatment protocols.Group 1 received conservative treatment ( n =54 ) and Group 2 received surgical treatment ( n =27 ).In Group 1,3 patients (5.6%) had stone-residual:1 girl had calculus of 0.4 cm in diameter in the left kidney and 2 girls had calculus of 0.3 cm in diameter in the right kidney.In Group 2,2 patients (7.4%) had stone-residual,1 boy had crystallization of 0.2 cm in diameter in the right kidney and 1 boy had calculus of 1.5 cm in diameter in the left kidney,positive stone was confirmed by X-ray and accepted percutaneous nephrolithotomy.Urinary microalbumin levels were significantly increased in the children with melamine-induced urolithiasis compared with the control group (P <0.01 ).Blood urea nitrogen and serum creatinine were within the normal range with no significant difference between the 2 groups. ConclusionsAt one-year follow-up most of the children exposed to melamine-tainted infant formula in both treatment groups had returned to a healthy state,suggesting a satisfactory outcome for both treatment options.However,surgery is recommended in patients with stoneresidual > 10 mm.

BACKGROUND:Acupotomy is an effective method for the clinical treatment of osteoarthritis,with affirmed clinical outcomes,but the specific mechanisms remain unclear OBJECTIVE:To investigate the role of acupotomy in modulating chondrocyte autophagy to promote chondrocyte homeostasis in osteoarthritis. METHODS:Twenty-eight New Zealand rabbits were randomly divided into control group,osteoarthritis group,acupotomy group,and hyaluronic acid group,with seven rabbits in each group.The knee osteoarthritis rabbit model was prepared using the Videman method in the latter three groups.After modeling,the control group and osteoarthritis group received no interventions.The acupotomy group received acupotomy treatment 15 minutes per time,once a week,while the hyaluronic acid group received intra-articular injection of hyaluronic acid once a week,with a continuous treatment duration of 5 weeks.The day after the final intervention,knee joint macrostructure was observed using DR imaging,chondrocyte ultrastructure was examined through transmission electron microscopy,apoptosis of chondrocytes was assessed using Tunel staining,and western blot analysis was used to detect the expression of proteins related to the PI3K/Akt/mTOR pathway. RESULTS AND CONCLUSION:The DR imaging results revealed that the osteoarthritis group exhibited narrowed knee joint spaces and the formation of periarticular osteophytes,while the hyaluronic acid group and acupotomy group showed widened knee joint spaces with a reduction in periarticular osteophytes.Transmission electron microscopy results demonstrated a decreased number of autophagosomes in chondrocytes in the osteoarthritis group,along with nuclear shrinkage,nuclear membrane rupture,incomplete organelle morphology,and a clear tendency towards cell death.In contrast,both the hyaluronic acid group and acupotomy group exhibited a significant increase in autophagosomes,intact nuclear membranes,and a well-preserved cellular state.Tunel staining results indicated a considerable decrease in the number of apoptotic cells in the hyaluronic acid group and acupotomy group compared with the osteoarthritis group.Western blot results revealed that,compared with the control group,the expression levels of Beclin1,Cath D,and LC3II/LC3I were significantly decreased in the osteoarthritis group(P<0.05),while the expression levels of p-Akt/Akt and p-mTOR/mTOR were significantly increased(P<0.05);compared with the osteoarthritis group,the expression levels of Beclin1,Cath D,and LC3II/LC3I were significantly increased in both the hyaluronic acid group and acupotomy group(P<0.05),while the expression levels of p-Akt/Akt and p-mTOR/mTOR were significantly decreased(P<0.05).To conclude,acupotomy intervention can modulate the PI3K/Akt/mTOR signaling pathway to enhance the autophagic level in chondrocytes,thereby maintaining chondrocyte homeostasis.This ultimately leads to a slowdown in cartilage degeneration.
