Abstract
To summarize the clinical experience of sandwich-shaped resection and cheiloplasty in the treatment of macrocheilia secondary to arteriovenous malformation, and to observe its clinical efficacy and complications. The clinical data of 27 patients with macrocheilia secondary to arteriovenous malformation who received surgical treatment from January 2018 to October 2020 in Linyi Cancer Hospital were retrospectively analyzed. There were 14 males and 13 females. The median age was 4.5 years (ranged from 2 to 57 years). There were 18 cases of upper lip and 9 cases of lower lip. All patients had received interventional embolization sclerotherapy for 5 to 10 times before surgery with unsatisfied effect. There was no obvious improvement in the appearance,whereas 3 cases progressed presenting as abnormal enlargement. Sandwich-shaped resection and cheiloplasty was performed in all the patients. Histopathological examinations confirmed arteriovenous malformations in all 27 cases. Twenty-six patients received one course of operation and one received two courses. Partial mucosal necrosis occurred in 1 case and healed after dressing change, while the rest healed by first intention. Local recurrence occurred in 2 cases within 6 months after operation. A four-level standard was used for long-term evaluation, and 24 cases got grade Ⅲ (good), three cases got grade Ⅱ (moderate) after 1 to 3 years of follow-up. Sandwich-shaped resection and cheiloplasty can achieve good long-term efficacy with excellent appearance and function. Due to its advantages of hidden incision and three-dimensional resection and reservation, it is worthy of further clinical promotion.

Abstract
OBJECTIVES To evaluate the safety and feasibility of microwave ablation for treating venous malformations (VMs) with severe localized intravascular coagulopathy (LIC). PATIENTS AND METHODS Data for patients with the diagnosis of VMs coupled with severe LIC who underwent color Doppler-guided microwave dynamic ablation between January 2017 and June 2019 were retrospectively reviewed and analyzed. All patients had previously received sclerotherapy or other treatments with poor outcomes and gradual aggravation of coagulation abnormalities. Microwave treatment with "dynamic ablation" was performed with real-time color Doppler monitoring and was repeated if necessary after 3 months. Low-molecular-weight heparin (LMWH) was used to control consumptive coagulopathy. The therapeutic efficacy including coagulation function and lesion size was evaluated using the four-level scale developed by Achauer. RESULTS Among 15 patients with extensive diffuse or multiple VMs, 10 patients presented with lesions in a single lower extremity, one in both lower extremities and the perineum, one in both upper extremities and the trunk, and three with multiple lesions. The patients underwent a total of 74 microwave ablation sessions, with an average of 4.9 sessions per person. Coagulation abnormalities were temporarily aggravated in 59 sessions within the first seven days post-ablation but improved to grade II (fair) a week later. From six months to three years after the ablation, the lesions improved to grade IV (excellent) in one patient, grade III (good) in six patients, and grade II (fair) in eight patients. Moreover, the coagulation function improved to grade IV in four patients, grade III in eight patients, and grade II in three patients, resulting in an efficiency rate of 80% (12/15). Post-ablation complications included fever, hemoglobinuria, and elevations in aspartate aminotransferase, lactate dehydrogenase, and alanine aminotransferase. The patients with fever and hemoglobinuria recovered after specific therapeutic measures, but elevations in aspartate aminotransferase, lactate dehydrogenase, and alanine aminotransferase recovered spontaneously without further interventions. CONCLUSIONS Ablation coupled with anticoagulation can effectively treat VMs in patients with severe LIC and improve the long-term coagulation function.

Abstract
Objective: To explore the clinical classification of microcystic lymphatic malformations of tongue and observe the treatment of microcystic lymphatic malformations of tongue by retrospective analysis, in order to provide reference for clinical practice. Methods: From October 2005 to October 2015, the complete data of 220 cases of microcystic lymphatic malformations of tongue (115 males and 105 females) received and treated in Provincial Special Department of Vascular Anomalies, Linyi Tumor Hospital was analyzed retrospectively. The age ranged from 8 months to 52 years old, with a median age of 16 years old. All patients were followed up for 3 years, and according to their clinical manifestations, they were divided into three types: localized type of 23 cases, diffuse type of 161 cases, and megaloglossia type of 36 cases. Injection with pingyangmycin merely was performed on 58 cases, whereas merely surgery on 20 cases, injection with pingyangmycin combined with high frequency electrocoagulation on 55 cases, and surgery combined with injection with pingyangmycin on 87 cases. The therapeutic effect was evaluated according to the grade 4 standard. The χ(2) test was used for statistical analysis of count data. Rank sum test was used for statistical analysis of ranked data. Results: The percentage of surgery merely of localized type was 87.0% (20/23), significantly higher than that of other types of lesions [0% (0/197)] (χ(2)=178.060, P<0.001). The percentage of injection with pingyangmycin of diffuse type was 100% (161/161), significantly higher than that of other types of lesions [66.1% (39/59)] (χ(2)=60.034, P<0.001). The percentage of surgery combined with injection with pingyangmycin of megaloglossia type was 100% (36/36), significantly higher than that of other types of lesions [27.7% (51/184)] (χ(2)=65.800, P<0.001). After follow-ups for 3 to13 years, there were 0 cases of gradeⅠ, 11 cases of grade Ⅱ, 50 cases of grade Ⅲ, and 159 cases of grade Ⅳ. There were statistically significant differences in clinical efficacy among different clinical types (H=158.668, P<0.001). The percentage of level Ⅳ efficacy of localized type, diffuse type and megaloglossia type were 100% (23/23), 82.6% (133/161) and 8.3% (3/36) respectively. Local mucosa ulcer appeared in 45 cases and was cured through oral care and expectant treatment. Fever occurred in 28 cases and returned to normal within 24 h after expectant treatment. The lingual frenum was shortened in 16 cases. There were 12 cases with mild tongue swelling, 6 cases with influence on eating but without influence on breathing, and recovered spontaneously one week later. Conclusions: The choice of different treatment methods of microcystic lymphatic malformations of tongue should be made according their clinical classification. The only surgical resection is recommended for localized protrude lesions. Injection with pingyangmycin in high tension combined with surgical resection or high frequency electrocoagulation is effective for diffuse lesions. Surgical resection combined with injection with pingyangmycin is suitable for the patients with megaloglossia type.

Abstract
Objective: To analyze the clinical data and summarize therapeutic experiences of cervicofacial venous malformations involving isthmus faucium area. Methods: Clinical records from 143 patients with venous malformations involving isthmus faucium area treated at our hospital between January 2012 and January 2016 were reviewed. There were 70 males and 73 females. Age ranged from 1 to 52 years old, with a median age of 14.5 years. There were 19 cases with lesions involving in only 1 subanatomic area above and 124 cases with lesions involving in more than 1 subanatomic areas, including 63 cases with lesions involving in more than 2 areas. There were 50 patients presenting with additional maxillofacial and cervical lesions. Clinical symptoms included snoring (n=98), indistinct phonation (n=49), and tonsil hypertrophy more than degree Ⅱ (n=19). Tracheotomy was performed in 3 patients prior to hospitalization, contigency tracheotomy during hospitalization in 10 patients, and oral trachea cannula in other patients. All therapeutic procedures, including single chemical ablation with ethanol injection (n=94), single lesion resection (n=9) and both of them (n=40), were performed under general anesthesia. Treatment remedies included mesh suture, macroglossia reduction and excision of maxillofacial and cervical lesions for patients presenting with extensive malformations extending to maxillofacial and cervical area. Tonsil resection were done in patients having tonsil venous malformations or tonsil hypertrophy more than degree II. Achauer's 4-grade criterion was applied to evaluate the treatment outcomes. SPSS 18.0 software was used to analyze the data. Results: Trachea cannula were not extubated untill 24 to 48 hours after treatment. Emergency tracheotomy was done in 2 cases after extubations because of dyspnea, and successful extubations were obtained in other cases. There were no advents of pulmonary vascular spasm or pulmonary embolism. There was significant difference between before and after operation (snore: χ(2)=105.431, ambiguous pronunciation: χ(2)=59.698, tonsil hypertrophy more than degree Ⅱ: χ(2)=33.530, all P<0.01). The patients were followed-up for 1-4 years, and there were 123 cases at grade Ⅳ (complete disappear of lesions in 62 cases without recurrence), 17 at grade Ⅲ , 3 at grade Ⅱ, and no case at gradeⅠ. Conclusions: Chemical ablation with ethanol injection for venous malformations involving isthmus faucium area is recommended, wheras combined remedies including injection, mesh suture, macroglossia reduction, and excision of cervicofacial lesions are suggested in treatment of extensive lesions extending to maxillofacial and cervical area. Tonsil resection should be done in patients having tonsil venous malformations or tonsil hypertrophy more than degree Ⅱ, which is safe and highly effective, with good reservation of function, in the treatment of maxillofacial and cervical venous malformations involving isthmus faucium area.

Abstract
Non-selective β-blocker propranolol has been proved by FDA as the first-line agent for infantile hemangioma (IH) with dramatic response. To reduce the side effects caused by systemic administration of propranolol, timolol maleate treatment has been increasingly used as an alternative to systemic β-blockers and watchful waiting for many IH patients in recent years. However, the appropriate indications, drug dosage, dosing regimen, time for initiation, optimal duration, monitoring for side effects still remains controversial. To standardize the use of topical timolol in treating IH, avoid overtreatment or under-treatment, as well as minimize complications, a Chinese expert consensus on the use of topical timolol treatment of IH has been approved and written by a multidisciplinary experts group based on an up-to-date literature review and repeated discussion, which can be used to reduce inappropriate variations in clinical practice and to promote the delivery of high quality, evidence-based health care for IH patients.

Abstract
Infantile hemangioma (IH) is one of the most common benign vascular tumors in children. A variety of treatment methods have been documented for the management of IH over the past years, including pharmacotherapy via oral administration or injection of corticosteroids, vincristine, alpha interferon and bleomycin; laser therapy, radionuclide therapy, cryotherapy and excisional surgery. The therapeutic efficacy of each treatment modality is variable, while adverse effects or complications are common and sometimes serious. Since the serendipitous discovery of propranolol, a nonselective beta-adrenergic receptor blocker, being very efficacious in treating IH in 2008, oral propranolol has earned a role as a first-line medical therapy for complicated IH. However, the appropriate drug dosage, dosing regimen, time for initiation, optimal duration, monitoring for side effects remains controversial. To standardize the use of propranolol in treating IH, avoid overtreatment or under-treatment, as well as minimize complications, a Chinese experts consensus on the use of oral propranolol for treatment of IH has been approved and written by a multidisciplinary experts group based on an up-to-date literature review and repeated discussion.

Abstract
OBJECTIVE To search for new targets and novel methods of anti-leukemia treatment and to discuss the mechanism of silencing the livin gene using small RNA interference technology to induce apoptosis in the K562 leukemia cell line. METHODS We designed and synthesized livin-specific small interference RNA (siRNA). Transfected K562 cells were cultured. Reverse-transcription polymer chain reaction (RT-PCR) was used to detect livin mRNA expression. Protein expression for livin was detected using Western blotting. A non-transfected group was used as a control. Meanwhile, vectors carrying enhanced green fluorescent protein (EGFP) were transfected as a positive control and flow cytometry was used to determine the transfection efficiency by detecting green fluorescence. The rate of apoptosis was determined using the annexin V and propidium iodide double-staining method. ELISA was used to determine the activity of Caspase-3. RESULTS The transfection efficiency of electroporation was as high as 50%. The siRNA sequences could knockdown livin gene expression at both the mRNA and protein levels. Apoptosis rate of the cells was 27.41 ± 2.30% 48 h after transfection with specific siRNA. This was significantly higher than that of the control group (9.63 ± 0.89%, p < 0.05). The 48-h apoptosis rate of the combined effect group VP-16 (5 µmol/L) and transfection rate was 45.1 ± 4.40%, which was significantly elevated (p < 0.05) compared with the groups treated with only VP-16 or by transfection. CONCLUSIONS Caspase-3 activity in cells transfected with siRNA was significantly elevated compared to the cells in the non-transfected groups (p < 0.05).

Abstract
We examined the effect of E-cadherin expression on epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) molecular targeted therapy sensitivity/resistance. We treated MCF-7, MDA-MB-231, T24, SiHa, H460, SK-HEP-1, MHCC97-H, and THP-1 cells with the EGFR-TKIs PD153035 and gefitinib, and then tested the drug-resistance and sensitivity using the MTT method, calculated IC50 values for each cell line, and compared the results to E-cadherin content. The MTT assay was used to determine the survival rates of MCF-7, MDA-MB-231, T24, SiHa, H460, SK-HEP-1, MHCC97-H, and THP-1 cells upon the action of EGFR-TKI (PD153035, gefitinib). For PD153035, the IC50 in MCF-7, MDA-MB-231, T24, and SiHa cells differed from that of H460, SK-HEP-1, MHCC97-H, and THP-1 (P < 0.05). Following gefitinib treatment, the IC50 values of MCF-7, MDA-MB-231, T24, and SiHa cells differed from those of H460, SK-HEP-1, MHCC97-H, and THP-1 cells (P < 0.01). The survival rate of MCF-7, MDA-MB-231, T24, and SiHa cells clearly decreased with increasing drug concentration, indicating the cells were sensitive to the drugs and that E-cadherin expression was positive; however, H460, SK-HEP-1, MHCC97-H, and THP-1 cells showed no significant decreased with increasing drug concentration, indicating that they were resistant to the drugs and that E-cadherin expression was negative. The survival rate of epithelial tumor cells through the action of EGFR-TKI is related to E-cadherin expression. E-cadherin may play a significant role in the sensitivity regulation of EGFR molecular targeting treatment. E-cadherin may provide important clues for selecting proper EGFR-TKI molecular targeting treatment.

Abstract
We experimentally demonstrated dual-wavelength synchronous operation of a high-power passively mode-locked 2-μm Tm:CaYAlO4 (Tm:CYA) disordered crystal laser with semiconductor saturable absorber mirror (SESAM) as mode locker. The mode-locked laser emitted an average output power as high as 830 mW with pulse duration of 35.3 ps and repetition rate of 145.4 MHz. The mode-locking dual wavelengths were centered at 1958.9 nm and 1960.6 nm, respectively. Autocorrelation trace clearly shows beating pulses with pulse width of 3.5 ps and repetition rate of 0.13 THz.

Abstract
We have demonstrated a diode-pumped passively mode-locked femtosecond Nd,Y:CaF2 disordered crystal laser for the first time to our knowledge. By choosing appropriate Y-doping concentration, a broad fluorescence linewidth of 31 nm has been obtained from the gain linewidth-variable Nd,Y:CaF2 crystal. With the Nd,Y:CaF2 disordered crystal as gain medium, the mode-locked laser generated pulses with pulse duration as short as 103 fs, average output power of 89 mW, and repetition rate of 100 MHz. To our best knowledge, this is the shortest pulse generated from Nd-doped crystal lasers so far. The research results show that the Nd,Y:CaF2 disordered crystal will be a potential alternative as gain medium of repetitive chirped pulse amplification for high-peak-power lasers.

Abstract
BACKGROUND Oral propranolol (PRN) has recently been shown to be highly effective for infantile hemangiomas (IHs), and is currently recommended as the first-line treatment of complicated IHs. However, the therapeutic mechanism(s) still remain unclear. METHODS In this study, we tested hemangioma-derived stem cells for expression of vascular endothelial growth factor (VEGF) in vitro and studied the inhibition of VEGF expression. We used PCR, Elisa, Western blotting and immunohistochemistry in vivo and in vitro trial. RESULTS The study demonstrated that application of PRN at a "normal" concentration equivalent to plasma concentration did not inhibit proliferation or promote apoptosis of hemangioma derived stem cells (HemSCs) isolated from IH patients. PRN suppressed expression of vascular endothelial growth factor (VEGF) and basic Fibroblast Growth Factor (bFGF) in HemSCs in vitro. Morphological, histological and immunohistological improvement were observed in vivo using murine IH model in which HemSCs pre-treated with PRN were implanted into BALB/c-nu mice. In the pre-treated HemSC grafts, mean micro-vessel density (MVD) significantly decreased and protein levels of VEGF markedly decreased, while bFGF was still detectable. CONCLUSIONS The results suggested PRN inhibited angiogenesis via down-regulating the expression of vascular endothelial growth factor in hemangioma derived stem cell. These findings provide critical insight into the potential mechanisms of PRN action on IH.

Abstract
Propranolol (PRN) has recently been recommended as the first-line medicine for complicated infantile hemangiomas (IHs), because of the significant effect. However, no pharmacokinetic parameters have ever been reported for infants who receive PRN treatment for IH. In this study, we show that plasma PRN concentration is affected by the frequency of administration of PRN. A single daily administration of PRN (1 mg/kg/d) resulted in an early elevation of plasma PRN compared to a twice a day administration of the same dose. In contrast, the twice a day application resulted in a more prolonged expression at a later time-point. Our findings provide pharmacokinetic parameters of PRN action in IH for clinic.

Abstract
OBJECTIVE To investigate the role of serum basic fibroblast growth factor (bFGF), estradiol (E2) and urine bFGF in differentiating infantile haemangiomas from vascular malformations. METHOD Between October 2007 and January 2009, 97 patients with haemangiomas and 25 patients with vascular malformations who had not been treated previously were included in this prospective study. Forty-eight patients with cleft lip and/or palate were selected as controls. The age of all subjects ranged from 1 to 30 months. The serum and urine levels of bFGF were determined by enzyme-linked immunosorbent assay (ELISA). The serum levels of E2 were examined via radioimmunoassay. All data were analysed with SPSS 11.5 software package. RESULTS The concentration of serum and urine bFGF was significantly different among the three groups (haemangiomas, vascular malformations and controls) (P = 0.027, P = 0.001). Significantly different urine bFGF levels were found in patients with proliferating and involuting haemangiomas (P = 0.04). The serum E2 levels were significantly higher in patients with haemangiomas than vascular malformations (P = 0.001) and controls (P = 0.001). CONCLUSION Serum bFGF and E2 as well as urine bFGF can be used to supplement the clinical diagnosis of congenital vascular anomalies. Urine bFGF combined with serum E2 may be the most potential markers for diagnosing haemangiomas and determining the proliferating stage of haemangiomas.

Abstract
OBJECTIVE To summarize the efficacy and safety of employing pneumatic compression therapy in infants with Kasabach-Merritt phenomenon (KMP). METHODS Seventeen patients with KMP (11 males, 6 females) were treated with pneumatic compression therapy from October 1997 to May 2008. And their clinical characteristics, course of treatment and clinical and laboratory data were retrospectively analyzed. Among 17 patients, 8 cases were located in trunk, 5 in lower extremities and 4 in upper extremities. The diameters of lesions exceeded 8 cm in all patients. The platelet count was all < 100 x 10(9)/L while hemoglobin < 110 g/L and fibrinogen < 2.0 g/L. The self-designed device for pneumatic compression hemangioma therapy was employed (Patent No: ZL97232266. 3). Biopsy and exairesis were performed from the local lesions with KMP in order to determine the pathological features. RESULTS Two patients were cured after pneumatic compression therapy for 4 and 6 months respectively, and their lesions disappeared, blood parameters became normal and remained relapse-free after a 5/11-year follow-up. Eleven patients were effective after pneumatic compression therapy for 4 - 6 months, and improvement was demonstrated after 6 - 24 months follow-up without any treatment. Two patients showed improvement after pneumatic compression therapy for 6 months after a follow-up for 5 months or 2 years without progression. After a 6-month pneumatic compression therapy, 2 ineffective patients underwent surgical resection. There were 14 cases of kaposiform hemangioendothelioma (KHE) and 3 cases of tufted hemangioma (TA). CONCLUSION Pneumatic compression therapy has definite curative effects for KMP lesions in extremities and trunk and its side effects are fewer.
