OBJECTIVE: To realize the application of nasal obstruction symptom evaluation (NOSE) and Epworth sleep score (ESS) before and after nasal cavity ventilation expansion techniques. METHOD: Forty-two OSAHS patients with nasal obstructive symptoms were diagnosed by clinical symptoms and polysomnography. Nasal cavity ventilation expansion technique was performed. Before and after the surgery, the NOSE and ESS were used to compare the difference. Postoperative data were obtained at least 3 months later. RESULT: Compared the data before and after operation, the NOSE and ESS were significantly decreased respectively (P<0. 05), there is no significant difference between 3 groups (P>0. 05). CONCLUSION The result suggest that OSAHS patients taking nasal cavity ventilation expansion operations showed improvement in severity of nasal obstructive symptoms and daily sleepy.

Objective To investigate the epidemiological features of critical patients in our emergency rescue area.Methods The ages,genders,time distribution of entering and turning out,disease scores and mortality rates of 2987 critical care patients rescued in emergency department of our hospital in 2011 were retrospectively analyzed.Results Circulatory,neurological diseases and respiratory diseases were the top three critical diseases in the emergency department.More male cases were received than female cases.Senior citizens aged from 60 to 79 were the largest group needing rescue.The diseases contributed to the top three mortality rates were sudden death out of hospital,hematological diseases and respiratory diseases. Peak time of the rescuing were December and April of the year and 16:00 to 20:00 of the day.Conclusions Resuing critical care patients is the emphasis of the emergency department.Promptly solving fatal problems and sending patients to relevant units as soon as possible is the necessary.Given the main targets are elderly patients with cardiac or cerebrovascular diseases as well as respiratory diseases,emergency staff and resources should be arranged and assigned properly according to the distribution features of the critical patients.Rescue green channel of several fatal diseases could be built to establish cooperative teams and improve the success rate of rescuing.Health education should also be strengthened to promote the emergency treatment knowledge for the high risk population.

OBJECTIVE: To investigate the composition of gut microbiota and its correlation with the severity of behavior symptoms in children with autism spectrum disorder (ASD). METHODS: A total of 30 children with ASD were enrolled as the ASD group, and 20 healthy children matched for age and sex were enrolled as the healthy control group. Related clinical data were analyzed. The V3-V4 hypervariable regions of the bacterial 16S rRNA gene in fecal samples were sequenced. The severity of behavior symptoms in children with ASD was assessed using the autism behavior checklist. The Spearman's correlation analysis was used to investigate the correlation between gut microbiota and the severity of behavior symptoms in children with ASD. RESULTS: There was a significant difference in the composition of gut microbiota between the two groups. Compared with the healthy control group, the ASD group had significant reductions in Shannon index and Shannoneven index (P<0.05), as well as a significant reduction in the percentage of Firmicutes and a significant increase in the percentage of Acidobacteria in feces (P<0.05). In the ASD group, the dominant bacteria were Megamonas, Megasphaera, and Barnesiella, while in the healthy control group, the dominant bacteria were Eubacterium_rectale_group, Ezakiella, and Streptococcus. In the children with ASD, the abundance of Megamonas was positively correlated with the scores of health/physical/behavior and language communication (P<0.05). CONCLUSIONS The development of ASD and the severity of behavior symptoms are closely associated with the composition of gut microbiota.

The aim of this study was to explore cytogenetic characteristics of acute promyelocytic leukemia (APL) and compare the interphase fluorescence in situ hybridization (I-FISH) with conventional cytogenetic (CC) analysis. A total number of 157 APL patients were recruited in this study, and the I-FISH and CC were applied to analyze cytogenetic features. Chromosome samples of bone marrow cells were prepared by short-term culture. Out of all 157 cases, 136 were observed with CC assay, 66 with I-FISH, of which 45 samples were analyzed with both methods. The results showed that among all 136 CC samples, t(15;17)(q22;q21) was found in 120 cases, of which 107 cases was isolated t(15;17)(q22;q21) abnormality, 13 cases was complex abnormalities and 12 case without mitotic figure. Among all 66 cases of I-FISH group, PMI/RARα fusion gene was found in 64 cases (97.0%), suggesting that I-FISH group was more sensitive than CC group (p = 0.041). It is concluded that combination of I-FISH and CC techniques plays a pivotal role for diagnosis and detection of minimal residual disease in APL.

In order to evaluate the cytogenetic features and clinical significance of chronic myeloid leukemia (CML), chromosome preparation of bone marrow cells was made by using 24-hour culture, and R-banding technique was employed for karyotyping in 362 patients with CML. The patients were divided into two groups of chronic phase (CP) and blast crisis (BC). The results showed that the incidence of additional chromosome, variant translocation and Philadelphia (Ph) negative, bcr/abl positive CML with abnormal chromosomes in CP group were 70 cases (26.1%), 19 cases (7.1%), 4 cases (1.5%), and were 50 cases (53.2%), 8 cases (8.5%), 4 cases (4.3%) in BC group. Among the 362 cases, 324 cases (89.5%) were Ph positive. Classic translocation was found in 297 cases (91.7%) and variant translocation in 27 cases (8.3%), including 13 cases of simple variant, 13 cases of complex variant and 1 case of marked Ph. Special karyotypes were found in 120 out of 362 cases. Analysis of these karyotypes demonstrated that the most common numerical abnormalities were +Ph (21.7%), +8 (10.0%), +21 (10.0%), +19 (7.5%) and structure abnormalities were i(17q) (13.3%). In conclusion, compared to chronic phase, the incidence of additional chromosome, variant translocation and so on are much higher at in blast crisis. It is feasible to evaluate the progress of the disease by karyotype analysis.

Post-endoscopic retrograde cholangiopancreatography pancreatitis(PEP)is one of the most common complications after endoscopic retrograde cholangiopancreatography(ERCP).Numerous PEP prediction models have been established based on different statistical methods at home and abroad.The PEP prediction model,as a tool for evaluating and screening high-risk populations,can provide a basis for medical staff to find high-risk PEP patients early and take effective preventive measures.In recent years,new PEP prediction models have appeared one after another,but there is still a lack of recognized reliable prediction models in clinic.This article reviews the research status of PEP risk prediction models,aim to provide a direction for establishing a more reliable,accurate,and practical PEP risk prediction model in the later period.

Objective Few reports are seen comparing esophageal stent placement (ESP) and the endoscopic incision method (EIM) in the treatment refractory esophageal anastomotic strictures (EAS) following esophageal carcinoma resection (ECR). This study was to evaluate the effect ESP versus that of EIM in the treatment of refractory EAS after ECR. Methods We retrospectively analyzed the clinical data on 50 cases of post-ECR refractory EAS treated by ESP (n = 32) or EIM (n = 18) in our Center of Digestive Medicine between January 2012 and December 2018. We recorded and compared the pre- and post-operative dysphagia scores, post-operative complications and follow-up results between the two groups of patients. Results Compared with the EIM group, the patients of the ESP group had a remarkably lower dysphagia score post-operatively (1.4±0.5 vs 1.0±0.0, P<0.01), a smaller diameter of the dilated esophagus ([19.9±1.8] vs [11.0±1.9] mm, P<0.01), higher incidence rates mild and severe chest pain (P=0.022), and a higher rate of relief of esophageal stricture at 12 months after surgery (P<0.05). Conclusion EIM can rapidly relieve the symptoms of esophageal anastomotic stricture, while ESP may achieve a longer duration of relief. Both of the procedures are safe for patients with refractory esophageal anastomotic stricture.

HIV-1 reverse transcriptase (RT) plays an important role in HIV-1 life cycle. At present, the listed NRTIs and NNRTIs targeting the RT showed high efficiency as clinical first-line drugs. However, the rapid emergence of multidrug-resistant viruses and significant cumulative drug toxicities compromises antiretroviral therapy efficacy and limits therapeutic options. Therefore, there is an urgent demand for new types of RT inhibitors with novel mechanism of action to address this challenge. In recent years, additional inhibitors with novel mechanism of action have been reported, including nucleic acid competitive inhibitors, reverse transcriptase-directed mutagenesis inhibitors, primers/templates-competitive reverse transcriptase inhibitors, polymerase-RNase H inhibitors, reverse transcription initiation process inhibitors, peptide inhibitors etc., which have brought new hope to the development of novel anti-HIV drugs. This article focuses on the development of these inhibitors.
