Objective To observe the efficacy of self-made Arnebiae oil by our hospital on phaseⅠandⅡpressure ulcers. Methods A total of 324 pressure wounds of 283 cases collected from March 2014 to August 2015 were randomly divided into the observation group (145 cases) and the control group (138 cases). The control group received Kangfuxin solution in conjunction with conventional pressure ulcer care treatment, the observation group were treated with Arnebiae oil and conventional pressure ulcer care treatment. The therapeutic effect and healing time of both groups were compared. Results Arnebiae oil was effective in 96.97% (160/165) of the pressure ulcer patients and cured 84.85% (140/165) patients in the observation group. Nearly 84.91%(135/159) patients were effective and 50.94%(81/159) patients were cured in the control group. There was statistical significance (χ2=42.93, 14.46, P<0.01). The healing time was (8.78±4.27) d in the observation group and (10.46±3.99) d in the control group with significance(t=2.88, P< 0.05). The healing rates of Arnebiae oil sacrococcygeal region, hips, legs and other parts were 87.96%(95/108), 9/10, 12/16, 9/9, significantly higher than those of the control group, 46.43%(39/84), 6/12, 3/9, 9/15, the difference had statistical significance (χ2=4.02-44.35, P<0.05). Conclusion Arnebiae oil com-bined with the overall care can improve the rate of wound healing in aged pressure ulcer, which is suitable for clinical application.

Objective To investigate the characteristics of common deafness genes mutation from 222 sensori-neural hearing loss patients in Guangxi province.Methods A deafness-related gene mutations detection kit was used to detect 15 mutation sites in four deafness-associated genes.A total of 222 hearing impaired patients,who were selected from January 2015 to April 2016,were tested.The samples that could not be diagnosed with DNA mi-croarray were subjected to PCR and sequenced to detect other mutations.Results Among the 222 patients with sen-sorineural deafness,the total mutation rate was 10.36% (23/222),including GJB2 235delC homozygous in 3 cases (1.35%),235delC single heterozygous mutation in 8 cases (3.60%),35delG single heterozygous mutation in 2 cases (0.90%),GJB2 235delC and 109 A>G mutations in 2 cases (0.90%),SLC26A4 1229C>T homozygous in 2 case (0.90%),IVS7-2 A>G heterozygous mutation in 2 cases (0.90%);IVS7-2A>G,IVS11+47T>C and 1548 insC mutations in 2 cases (0.90%);GJB3 538C>T heterozygous mutation in 1 cases (0.45%);Mitochondrial 12S rRNA gene heterogeneous mutations in 1 case (0.45%).One of them carry both two mutations:GJB2 235 del C and SLC26A4 1226 G>A.Conclusion The results indicate that GJB2 and SLC26A4 were the main genes in this study,and in Guangxi province the mutation rate is significantly lower than the national average level.3 new muta-tions (SLC26A4 IVS11+47T ! C,1548insC and GJB2 109A>G)were found.There may be some rare mutations among sites or genes caused deafness in Guangxi.

OBJECTIVETo identify predictors of left atrial appendage stunning after the use of electrical cardioversion to restore sinus rhythm in patients with non-valvular atrial fibrillation.

METHODSA total of 68 consecutive patients (45 men, 23 women, 60.5 +/- 8.7 years of age) with non-valvular atrial fibrillation undergoing electrical cardioversion were enlisted in this study. Clinical and echocardiographic variables were analyzed by univariate regression and multivariate logistic regression to investigate the relationship between occurrences of left atrial appendage stunning and these factors.

RESULTSUnivariate analysis revealed that, in comparing patients without and with left atrial appendage stunning, there were significant differences in the duration of atrial fibrillation > 8 weeks (32.3% vs 75.5%, P < 0.001), left atrial diameter > 50 mm (29.0% vs 54.1%, P < 0.05), left atrial emptying fraction (31.5% +/- 7.8% vs 27.1% +/- 8.5%, P < 0.05), left ventricular ejection fraction < 50% (38.7% vs 67.6%, P < 0.05), maximum electrical energy (96.8 J +/- 65.8 J vs 156.8 J +/- 100.8 J, P < 0.01), cumulative electrical energy 146.8 J +/- 142.6 J vs 290.5 J +/- 242.1 J, P < 0.01) and number of electrical cardioversion shocks (1.7 +/- 0.9 vs 2.43 +/- 1.20, P < 0.05). However, backward stepwise multivariate logistic regression analysis identified as significant and independent predictors of left atrial appendage stunning only duration of atrial fibrillation > 8 weeks (OR = 7.249, 95% CI = 1.998 - 26.304, P < 0.01), left atrial diameter > 50 mm (OR = 3.896, 95% CI = 1.105 - 13.734, P < 0.05), left ventricular ejection fraction < 50% (OR = 4.465, 95% CI = 1.51713.140, P < 0.01) and cumulative energy of electrical cardioversion (OR = 1.004, 95% CI = 1.000 - 1.008, P < 0.05).

CONCLUSIONSDuration of atrial fibrillation > 8 weeks, left atrial diameter > 50 mm, left ventricular ejection fraction < 50%, and cumulative energy of electrical cardioversion are independent predictors of left atrial appendage stunning. Anticoagulation treatment should be individualized for patients undergoing electrical cardioversion to reduce the risk of both cardioversion-related thromboembolic events and hemorrhagic complications caused by warfarin treatment.

The effective treatment methods of myelodysplastic syndromes (MDS) are limited. The patient's treatment plan is mainly based on individual differences and different risk levels [by revised International Prognostic Points System (IPSS-R)], including observation, erythropoiesis stimulating agents, iron elimination, immunosuppressive agents, lenalidomide, hypomethylating agents and hematopoietic stem cell transplantation (HSCT). The limitations of the treatment strategies are important exploration directions for future clinical trials. At present, multiple clinical trials for the treatment of MDS are underway, but it is still necessary to optimize therapies through integrating molecular and genetic data and applying them to clinical practice. This article reviews the current treatment approaches of MDS and looks forward to future research directions.

OBJECTIVETo assess the impact of stomach cancer on the Chinese population by epidemiological analysis of its mortality distribution.

METHODS1990-1992 data on stomach cancer mortality collected by sampling survey involved one tenth of the total Chinese population.

RESULTSThe crude mortality rate of stomach cancer in China was 25.2 per 10(5) (32.8 per 10(5) for males and 17.0 per 10(5) for females), which comprised 23.2% of the total cancer deaths from 1990 to 1992, making stomach cancer the leading cause of cancer death. The stomach cancer mortality rate of males was 1.9 times of that of females. The Chinese mortality rates of stomach cancer adjusted by the world population were 40.8 per 10(5) and 18.6 per 10(5) of males and females, which were 4.2-7.9 (of males) and 3.8-8.0 (of females) times of those in the developed countries. Age-adjusted mortality rates of stomach cancer in China have distinct geographical difference: form the lowest 2.5 per 10(5) to the highest 153.0 per 10(5) in the 263 surveyed localities, 15.3 per 10(5) in urban areas and 24.4 per 10(5) in rural areas giving a difference of 1.9 times.

CONCLUSIONThe prevention and treatment of stomach cancer in China, especially in the countryside and the under-developed areas in the northwest, should be a long-term focus in control of cancers of the digestive system. Urgent measures for prevention and early detection of stomach cancer should be taken.

OBJECTIVE: To explore the genetic basis for a Chinese pedigree affected with non-syndromic hearing loss (NSHL). METHODS: Commercialized gene chip was applied to detect common mutations associated with congenital deafness. Whole exome sequencing was carried out for patients for whom gene chip yielded a negative result. Candidate variants were verified by Sanger sequencing. RESULTS: Two patients from the pedigree were discovered to carry compound heterozygous variants of the TRIOBP gene, namely c.3299C>A and c.5185-2A>G. Their parents had normal hearing and were both heterozygous carriers of the above variants. Both variants had co-segregated with the disease phenotype in the pedigree and were unreported previously. CONCLUSION Pathogenic variants of the TRIOBP gene comprise an important factor for NSHL. The novel c.5185-2A>G and c.3299C>A variants discovered in this study have enriched the mutational spectrum of the TRIOBP gene and enabled molecular diagnosis and genetic counseling for the family.
