Objective:To explore the factors affecting the postoperative prognosis of early cervical squamous cell carcinoma and inves-tigate the different radiotherapy techniques. Methods:A total of 100 postoperative patients of early cervical squamous cell carcinoma treated in Affiliated Tumor Hospital of Xinjiang Medical University and Affiliated Tumor Hospital of Sun Yat-sen University from March to September 2013 were enrolled in our study. The prognostic factors for these patients were analyzed. After being subjected to differ-ent postoperative radiotherapy techniques, the efficacy and complications of the techniques were assessed for patients, including 50 cases of conventional radiotherapy (CRT) and 50 cases of image-guided radiotherapy (IGRT). Results:The 3-year overall survival rate was 89%, and the 3-year disease-free survival rate was 78%. The 3-year overall survival rates of the CRT and IGRT groups were 78.57%and 89.06%, respectively. The difference between these rates was statistically significant (P=0.034). The 3-year survival rates of the CRT and IGRT groups were 66.67%and 87.36%, respectively. The difference was statistically significant (P=0.042). The incidence of ear-ly and late complications in the CRT group was higher than that in IGRT group, and the difference of P<0.05 was statistically significant. Multivariate analysis showed that postoperative radiotherapy, parametrial invasion, lymph node metastasis, lymphovascular space in-vasion, perineural invasion, and deep stromal invasion were the independent risk factors for the prognosis of patients with early stage cervical squamous cell carcinoma. Conclusion:Early prognosis of cervical squamous cell carcinoma results from the interaction of mul-tiple factors. The 3-year survival rate of the IGRT group was significantly better than that of the CRT group in the early stage of cervical squamous cell carcinoma. IGRT alleviates acute and chronic toxicities and helps improve the quality of life of patients.

Objective To observe the efficacy of oropharyngeal muscle exercise for relieving obstructive sleep apnea (OSAS) among stroke survivors.Methods Fifty stroke survivors with moderate OSAS were randomly divided into an observation group and a control group,each of 25.Both groups were given routine drugs and rehabilitation,while the observation group was additionally provided with oropharyngeal muscle exercises during the daytime for 20 minutes twice a day for6 weeks.The control group received deep breathing therapy.Before and after the 6 weeks of treatment,both groups were evaluated using polysomnography.Their sleep quality and daytime sleepiness were measured using the Pittsburgh sleep quality index and the Stanford sleepiness scale.Any changes in the patients' pharyngeal morphology after exercise were evaluated using MRI.Results After the oropharyngeal muscle exercises,the apnea hypoventilation index and minimum SaO2 ％,the snore index and sleep quality improved significantly.Daytime sleepiness was significantly relieved.Some structural remodeling of the pharyngeal airvay was observed by MRI,including significantly larger retropalatal distance and shorter length of the soft palate.The retropalatal distance was positively and correlated with the duration of exercise while the length of soft palate correlated negatively.Conclusion Exercising the oropharyngeal muscles is a promising alternative treatment for stroke survivors with moderate OSAS.It improves the morphology of the oropharynx to relieve obstruction during sleeping.

This study reported two women with extreme obesity who underwent metabolic surgery due to their mutations in leptin receptor (LEPR).Genomic DNA was extracted from the anticoagulant blood samples of the two patients and their parents.A panel of genes related to metabolic diseases or whole exon sequencing was screened and the results were confirmed by Sanger sequencing.This is the first time that these three mutations in LEPR were reported.Two patients complained insatiety and early-onset obesity since childhood at clinics.Patient 1 was a 39-year-old woman with height 150 cm,weight 130 kg,and BMI 57.8 kg/m2.Serum leptin level was 156.4 μg/L.A homozygous mutation of c.2317G＞T was found in exon 15 of LEPR gene in patient 1,which was descended from her father and mother respectively.Patient 2 was a 37-year-old woman with height 158 cm,weight 167 kg,and BMI 67 kg/m2.Serum leptin level was 193.4 μg/L.Genetic analysis showed compound heterozygous mutations of c.1482delT and c.1892C ＞ A.Her father showed heterozygous c.1482delT mutation,and her mother carried heterozygous c.1892C ＞ A mutation.Two patients all underwent metabolic surgery with body weight reduction of about 22 kg and 40 kg respectively after first six months.However,the follow-up studies showed that the body weight of patient 1 rebounded to pre-surgery level in two years and patient 2 did not further lose weight in the following six months.
