Objective The purpose of the study was to compare the P63 expression in non-small cell lung cancer (NSCLC) between Xuanwei and other regions, and to investigate the relationship of P63 expression and biological behavior. Methods Immunohistochemical method was used. Results The results indicated that the expression of P63 in lung squamous cell carcinoma was extraordinarily high. P63 was related to the TNM staging system,tissue differentiation degree and lymph node metastasis,but not related to gender. In NSCLC,there was no significant difference of the P63 positive expression rate in the same pathological types, staging, tissue differentiation degree, lymph node metastasis and gender between Xuanwei and other regions. It indicated that the expression of P63 was not the reason why it was high incidence of lung cancer in Xuanwei region.

Objective To observe the therapeutic effect of intravitreal lucentis injections combined with laser photocoagulation for Coats disease.Methods This was a retrospective case series study.From August 2012 to December 2015,18 cases (18 eyes) were diagnosed as Coats disease with macular edema by FFA and OCT.All patients were treated at baseline using intravitreal lucentis injections.One week later,photocoagulation was performed by the guiding of FFA.Follow-up treatment was performed as necessary.The primary BCVA and central macular thickness (CMT) was measured postoperatively.The follow-up time was 16-24 months (mean 18.8 months).Results The mean number of lucentis injections was 2.6,and the mean number of laser treatment sessions was 1.8.The mean preoperative BCVA was (0.81 ±0.28) LogMAR,while the final visit was (0.76 ± 0.37) LogMAR (P =0.396).In 3 patients (16.7 ％),BCVA had improved by more than 3 lines,and 13 patients (72.2％)showed stable BCVA (changes within 2 lines of visual acuity),while in 2 patients,BCVA decreased by more than 3 lines (11.1％).The mean CMT improved significantly from (341.11 ±67.97) μm preoperatively to (277.83 ±51.59) μm at the fmal visit (P =0.030).Final BCVA was significantly correlated with preoperative BCVA (r =0.817,P ＜0.001).The final BCVA of patients with subfoveal hard exudates preoperatively was significantly worse than that of patients without such exudates (P =0.044).Conclusion Intravitreal lucentis injection combined with laser photocoagulation may be an effective treatment for Coats disease.It may stablize the visual acuity,decrease the CMT of Coats disease.The final BCVA is associated with preoperative BCVA and occurrence of subfoveal hard exudates.

Background and purpose:It was reported that many microRNAs (miRNAs) have close relation with carcinomas. miR-31 (microRNA-31) shows abnormal change in numerous cancers. China is one of the most high-risk areas of esophageal squamous cell carcinoma (ESCC). The aim of the present study was to investigate the expression of miR-31 in ESCC, and analyze the relationship of its expression with clinicopathological features and prognosis. Methods:The expression of miR-31 in KYSE410, EC1 and EC9706 cell lines, as well as 81 cases of ESCC tissues and adjacent normal esophageal tissues were detected by real-time reverse transcription-polymerase chain reaction (RT-PCR). The result was combined with clinical and follow-up data and statistical analysis was conducted. Results: MiR-31 was up-expression in 3 cell lines and 75.31% of the ESCC tissues. miR-31 up-expression was positively related to severer lymph node metastasis (P=0.043), deeper invasion of tumors (P=0.002) and advanced pathological stage (P=0.027). There was no relationship of miR-31 with other clinicopathological features (P>0.05). Furthermore, high expression of miR-31 was associated with poor progression-free survival (PFS) in 81 ESCC patients by Kaplan-Meier analysis (P=0.014) and by multivariate Cox analysis (P=0.021). Conclusion:Our results identiifed miR-31 may be a new diagnostic criteria and prognostic biomarker for ESCC.

Objective To evaluate the b value of diffusion-weighted(DW)MRI in distinguishing between benign and malignant breast lesions.Methods Three diffusion-weighted sequences were implemented with 500,1000 and 2000 s/mm~2 b values respectively on 95 breast lesions in 83 patients.All lesions were confirmed by pathology.The apparent diffusion coefficient(ADC)values and signal intensity (SI)were recorded and compared in different lesions(breast cancer,benign lesion,cyst and normal beast tissue)with the same b value and the same lesions with the different b values.Results(1)The mean ADC value and SI of breast cancer were 1.375?0.378 and 839.713?360.493 respectively with b= 500 s/mm~2,1.176?0.311 and 459.314?229.609 with b=1000 s/mm~2,0.824?0.198 and 243.825? 110.616 with b=2000 s/mm~2.The differences in the mean ADC value were significant between two type lesions(cancer and benign lesion,cancer and cyst,cancer and normal breast tissue)with b values of 500 s/mm~2 and 1000 s/mm~2.But the significant differenee was only seen between cancer and benign lesions when b value was 2000 s/mm~2.(2)The one-side upper limits of 95% confidence interval of mean ADCs were adopted as the point to separate the malignant from the benign lesions,the sensitivity was 70.92%, 70.73% and 69.77%,the specificity was 77.19%,75.70% and 54.76%,the accuracy was 77.12%, 74.32% and 62.35% respectively with b values of 500 s/mm~2,1000 s/mm~2 and 2000 s/mm~2.The areas under ROC eurves were Az_(500)=0.775?0.046(P0.05).Conclusion DWI MRI is useful for the differential diagnosis of breast lesions with b values of 500 s/mm~2 and 1000 s/mm~2.

Objective To describe the manifestations of the inferior phrenic arteries(IPA)supply to the pulmonary hemorrhagic lesions and to evaluate the safety and efficacy of transcatheter arterial embolization(TAE)of the IPA.Methods The clinical data and imaging findings of eighteen patients with the additional blood supply to the pulmonary hemorrhagic lesions from the IPA were evaluated retrospectively.The causes of the bleeding were lung malignancies in 9,bronchiectasis in 7,and chronic inflammation in 2 patients.TAE supplementally was performed in patients with IPA supply to the pulmonary lesions,using polyvinyl alcohol particles,gelatin sponge particles,and microcoils.Results Selective arteriogram demonstrates an enlarged IPA,with numerous branches and hypervascularity in all 18 cases, with tumor staining in 9,the contrast material extravasation in 6,and non-specific staining in 2 cases.In addition,IPA-to-pulmonary shunting was found in 9 cases.All the lesions supplying by IPA were adjacent to the pleurae,including adjacent to the diaphragmatic pleura in 11,the mediastinal pleura in 5,and the lateral pleura of the lower lobe in 2 cases.Technical success of IPA embolization was achieved in the 18 cases.Embolization of other nonbronchial systemic arteries(the internal thoracic artery in 7 and intercostal artery in 3)was performed at the same session.All bleeding ceased immediately after supplemental IPA embolization.Follow-up time ranged from 8 months to 4 years.Mild recurrent hemoptysis occurred in 3 patients at 1,2,6 months respectively,after the embolization.These patients were responsive to conservative management.Recurrent bleeding did not occur in 15 patients during the follow-up. Conclusion The pulmonary hemorrhagic lesions,especially adjacent to the diaphragmatic and mediastinal pleurae,can be supplied by IPA,and may result in clinical failure following BAE.Supplemental TAE of IPA is a safe and effective adjunct to BAE in the management of bronchial bleeding supplied by IPA.

Objective:To explore the strategies and complications of the submucosal tunneling endoscopic resection (STER) in the treatment of esophageal duplicated cyst (EDC).Methods:From January 2013 to December 2019, at Department of Gastroenterology, Taizhou Hospital of Zhejiang Province, the clinical data of 11 hospitalized patients with EDC diagnosed by pathological examination who underwent STER were collected. The clinical featured, computed tomography (CT) findings, endoscopic findings, postoperative efficacy, complications and pathological results after operation were summarized.Results:Among the 11 patients, there were 6 males and 5 females, the age ranged from 13 to 67 years, and the mean age was (43.0±18.2) years. One case presented with swallowing obstruction, 1 case with belching, 4 cases with upper abdominal pain, and the remaining 5 cases had no specific clinical symptoms. Under endoscopy, the lesions of 11 patients were hemispherical or mound-shaped with smooth surface submucosal masses in the esophageal cavity, which were soft to touch. Under endoscopic ultrasonography, they all appeared as hypoechoic masses with clear boundary located in the esophageal muscularis propria. The results of CT scan of 9 patients showed round low-density cystic masses, among them 7 cases showed mild enhancement. The maximum diameter of the cysts was 1.5 to 4.4 cm, with mean maximum diameter being (2.8±0.8) cm, and the maximum diameter of most patients (7 cases) were 2 to 3 cm. The other two patients showed only slightly thickened esophageal wall on CT. Five lesions occurred in the horizontal mediastinum of the lower esophagus. All the 11 patients underwent STER operation successfully, among them 6 patients received simple STER and the cysts were completely resected, and the other 5 patients received STER and cauterization with argon ion for the residual cyst wall. The pathological results after operation indicated that 6 cases were congenital esophageal cysts and 5 cases were bronchogenic cysts. The median follow-up time (range) of 11 patients was 42 months (12-86 months). Ten patients recovered well after the operation, and local recurrence, malignant transformation or metastasis were not found. One case had recurrence, and was treated with STER and cauterization with argon ion for residual cyst wall and cured. No complications such as bleeding, fistula, mediastinal infection or death occurred during and after operation in all the 11 patients.Conclusions:STER is a minimally invasive, safe and effective treatment for EDC, and may be a new treatment for EDC.

BACKGROUND: Glucocorticoid-induced osteoporosis has relationship with the down-regulation of osteoprotegedn expression. Osteoprotegerin could inhibit bone resorption in the animal experiment and clinical application for treating oestrogenic hormone deficiency osteoporosis. OBJECTIVE: To investigate the effects of exogenous recombinant osteoprotegerin fusion protein on glucocorticoid-induced osteoporosis in rats. DESIGN, TIME AND SETTING: Randomized grouping, controlled animal expenment was performed in the Institute of Orthopedics, Chinese PLA General Hospital between January 2006 and June 2008. MATERIALS: Sixty healthy male Wistar rats of clean grade; Dexamethasone was produced by Tianjin Jinyao Amino Acid Co., Ltd (Licenca No. H12020515). METHODS: Sixty rats were divided into 3 groups randomly with 20 rats in each. Control group: the rats were administrated with 0.9％ sodium chloride. Dexamethasone group: the rats were administrated with dexamethasone intramuscularly. Osteoprotegedn group: the rats were administrated with dexamethasone and recombinant osteoprotegerin intramuscularly. MAIN OUTCOME MEASURES: All rats were sacrificed at 12 weeks after administration. The urine calcium, phosphor, creatinine, bone mineral density, biomechanics tests of femur and vertebral body, were measured. Immunohistochemistry staining were performed to observe osteoprotegerin expression.RESULTS: Sixty rats were all involved in the final analysis. ①Compared with control group, udne calcium increased in the Dexamethasone group (P < 0.05); the bone mineral density of lumbar vertebra and femur decreased significantly (P < 0.05), especially lumbar vertebra (P < 0.01); biomechanics tests of femur and vertebral body (maximum load, maximum stress, elasticity load, elasticity stress, elastic modulus) decreased significantly (P < 0.05); immunohistochemistry staining showed that endogenous osteoprotegerin expressions were reduced significantly in bone marrow of Dexamethasone group (P < 0.01). ②Compared with Dexamethasone group, urine calcium decreased in the osteoprotegerin group (P < 0.01 ); the bone mineral density of lumbar vertebra and femur increased (P < 0.05); the parameters of biomechanics testa of femur and vertebral body increased (P < 0.05); the osteoprotegerin expression was not changed between Dexamethasone group and osteoprotegerin group.CONCLUSION: Glucocorticoid could inhibit osteoprotegerin expression in the bone followed by progressive bone loss and induce osteoporosis. Recombinant osteoprotegerin works effectively in inhibiting bone resorption after administrated with glucocorticoid, reduce bone resorption index, increase bone mineral index and bone strength, thus improving the osteoporosis which is induced by glucocorticoid.
