Objective:To analyze the advantages of IPSA combined with increasing cervical center dose in intracavitary and interstitial brachytherapy (IC/IS) for locally advanced cervical cancer.Methods:A total of 46 stage Ⅱ B cervical cancer patients with, local lesion size≥5 cm after 45 Gy/25f external intensity-modulated radiotherapy (IMRT) were recruited. Uterine tandem and needles were implanted, CT was performed, and then HR-CTV, rectum, bladder, sigmoid colon and the area of cervix increased dose (HR-cervix) were delineated, IPSA was used for optimization. According to whether the dose of HR-cervix was increased or not, all patients were divided into IC/IS+ HR-cervix group (group A) and IC/IS group (group B). The differences in dosimetric parameters were compared between two groups. Results:The relative uterine tandem dwell time was significantly extended in group A ( P<0.001). In group B, the V 150% and V 200% volumes of HR-cervix were increased from 63.94% and 30.80% to 91.54% and 64.06%. The D 90% and D 100% in group A were significantly lower than those in group B (both P<0.05). There was no statistical difference in organ at risk (OAR) dose. Conclusion:IPSA combined with increasing cervical center dose can meet the HR-CTV D 90% dose requirement, normal tissue dose limits, and can escalate the doses to local areas of the cervix.

Umbilical cord (UC) embolism is a rare, life-threatening complication of pregnancy. The exact cause of this condition is not yet known. Women with more than one UC abnormality are at risk of UC obstruction; this condition can lead to stasis, ischemia, and in some cases, thrombosis. However, many women with UC abnormalities remain undetected and may not be recognized until after birth. Here, we present a case involving the prenatal diagnosis and successful treatment of umbilical artery embolism in the third trimester with good maternal and fetal outcomes. The risk of UC embolism increases when more than one UC abnormality is identified in a single case. Ultrasound examination in the third trimester of pregnancy should be able to verify the existence of two arteries and one vein in the UC. If necessary, these results can be compared with ultrasound imaging acquired during the first trimester of pregnancy.

Objective To investigate the effect of cell proliferation and apoptosis induced by Pingyangmycin (PYM)and dexamethasone (DEX) on human umbilical vein endothelial cells (HUVEC)in vitro, so as to provide therotical evidence for treatment of aneurysm with PYMand DEX. Methods Control, PYM, DEX and PYM group were established after HUVEC were cultured for 24 hours. Cell morphology was observed by inverted microscope.The effect of cell proliferation and apoptosis were detected with CCK-8reagents and flow Cytometry. The apoptotic protein expression of caspase-3 was testedthrough Western blot. Results Descend of adherent cell density and the ascend of floating cells could be observed after treated with PYM and DEX for 24 hours. HUVEC could be inhibited effectively with concentration-dependent on PYM and DEX. The significant statistical difference of cell apoptosis rate between the group used for PYM alone and the group combined low-concentration PYM with DEX through Flow Cytometrywas found. There was significant statistical difference of apoptotic protein expression of caspase-3 through Western blot compared with the group used for PYM alone and the group combined low-concentration PYM with DEX. Conclusion PYM and DEXcould inhibitthe proliferation of HUVEC alone. The better effects could be observed combination low-concentration PYM with DEX , the mechanism of which might beapoptosis with low-concentration PYM and necrosis with high-concentration PYM.

OBJECTIVE To explore the expression of Maspin in invasive fungal rhinosinusitis (IFRS) and the value of Maspin in the diagnosis of IFRS. METHODS Forty two cases of fungal rhinosinusitis (FRS) were set as the experimental group, which included 12 cases of IFRS and 30 cases of noninvasive fungal rhino-sinusitis (NIFRS). At the same time, 30 cases of chronic rhino-sinusitis were set as control group. Immunohistochemistry (IHC) was used to detect the expression of Maspin. RESULTS Compared with the control group, the expression of Maspin in FRS group decreased statistically (t=-3.367, P<0.05). The IFRS group, compared with other two groups, had the lowest expression of Maspin (t=-3.390, P<0.05; t=-4.143, P<0.05). By using Maspin score of 5.70 as the cut-off point, the sensitivity and specificity for the diagnosis of IFRS was 91.7% and 88.3% respectively. CONCLUSION The expression of Maspin is very low in IFRS group. Down-regulation of Maspin expression may be a potential indicator for diagnosis of IFRS.

OBJECTIVES: To investigate the surgical outcomes of different uvulopalatopharyngoplasty (UPPP). METHODS: All subjects underwent overnight polysomnography and were evaluated using the Epworth sleepiness scale (ESS), the Quebec sleep questionnaire and the snoring scale at the baseline and 3 and 12 months following operation. The primary endpoint was the overall effective rate representing the sum of the surgical success rate and effective rate. RESULTS: The overall effective rate at 12 months post surgery was 55.6% for simple UPPP, 95.8% for UPPP+GA, and 92.3% for UPPP+TBA. The surgical success rate at 3 and 12 months postoperation for UPPP+GA or UPPP+TBA was significantly higher than simple UPPP (P<0.05). Marked improvement was observed in all patients in the snoring scale score and the ESS score 3 and 12 months following surgery compared to the baseline (P<0.05 in all). CONCLUSION: UPPP, UPPP+GA, and UPPP+TBA are all effective in improving the surgical outcome of obstructive sleep apnea hypopnea syndrome (OSAHS) patients with multilevel obstruction. UPPP+TBA appears to be the most effective in treating OSAHS patients.

We reported a case of children's OSAHS caused by the huge fibrolipoma in pharynx nasalis. The patient was a 10-years-old child who went to the hospital with the chief complaint of "Snoring and mouth breathing during sleep for 10 years". Imaging tests found one huge tumor in pharynx nasalis before the operation. The tumor was resected totally. The postoperative pathological diagnosis was fibrolipoma. No recurrence was noted during the follow-up visit one year postoperatively. The clinical features, diagnosis, treatment, pathology and prognosis were reviewed herein.
