Nearly one-third of individuals with overweight or obesity had metabolic syndrome.

OBJECTIVE: To observe the effect of tympanic injection of dexamethasone in the guinea pig endolymphatic hydrops and the change CFTR expression, to explore the effect of glucocorticoid treatment endolymphatic and its possible mechanism. METHOD: Thirty guinea pigs were divided into three groups: hormone group, water group, control group. The animals(hormone group, water group) in study were injected DDAVP 4 μg/kg in the first 7 d, and will increase to 6 μg/kg in the second 3 d. The control group was given normal saline, continuous 10 d. After twelfth days, the hormone group transtympanic injection of dexamethasone (5 mg/ml, 0.5 ml), and water group, control group transtympanic given normal saline (0.5 ml), continuous injection 5 d. Using immuno- histochemistry and Western blot to detect the cystic fibrosis transmembrane conductance regulator cochlear factor (CFTR) expression. RESULT: The water group ABR thresholds was significantly higher than that before the experiment (P < 0.01), and the water group was significantly higher than the rest of the groups (P < 0.01); Hormone group compared with the control group increased threshold value (P < 0.05). The control group had no endolym- phatic hydrops, the water group showed varying degrees of endolymphatic hydrops, cochlear duct and vestibular plus cochlear duct area ratio compared with the control group, hormone group was significantly higher (P < 0.01). hormone group area ratio was higher than the control group (P < 0.05). CFTR was primarily expressed in the stria vascularis, Corti's, spiral ligament, basilar membrane, cochlear ganglion,etc . The expression of CFTR in the water group was increased than that in the control group, and the hormone group (P < 0.01); the expression of hormone group increased compared with the control group (P < 0.05). CONCLUSION Tympanic injection of dexa- methasone can alleviate the desmopressin acetatein guinea pigs caused by membranous labyrinth, and the improve- ment of the hearing; Tympanic injection of dexamethasone can make the endolymphatic hydrops cochlea of guinea pigs decreased CFTR expression, indicating that the expression and possible mechanisms of CFTR intratympanic steroids reduce endolymphatic hydrops changes.

OBJECTIVE:To observe the clinical efficacy and safety of Yinzhihuang oral liquid in the adjuvant treatment of neo-natal breast-feeding faundice. METHODS:112 newborns with faundice were randomly divided into control group and observation group. Control group stopped breast-feeding for 3 d and given artificial feeding,as well as keeping warm,nutritional support, maintaining water and electrolyte and acid-base balance,blue light irradiation and severe patients were given liver protection,en-zyme inducers;observation group was additionally given Yinzhihuang oral liquid 10 ml,twice a day. The treatment course was 7 d. Clinical efficacy,and serum total bilirubin(TBIL)level before and after treatment,and incidence of adverse reactions in 2 groups were observed. RESULTS:The total effective rate in observation group was significantly higher than control group,the difference was statistically significant(P<0.05). After treatment,TBIL level in 2 groups was significantly lower than before and gradually de-creased with time,and observation group was lower than control group,the differences were statistically significant(P<0.05). The incidence of adverse reactions of 2 groups was no statistically significant(P>0.05). CONCLUSIONS:Based on the conventional treatment,Yinzhihuang oral liquid can be used in the adjuvant treatment of neonatal breast-feeding faundice,with good efficacy and good safety.

Objective Through investigation and training in the knowledge and skills of pre hospital emergency treatment in Xuzhou highway traffic policemen,we explored a more targeted and more effective first-aid skills training program.Methods Based on our hospital emergency center 91 highway traffic policemen were randomly assigned to 3 first aid skills training groups,group 1 received theoretical training and operational training,group 2 was given the same theoretical training and operational training after DVD player,group 3 took the same method as that of group 2,besides,situational training was given to group 3.The emergency treatment technique was evaluated post training.Results After the training,the scores of 3 groups were different from each other,group 3 had the best results compared with group 1 and group 2.Conclusions The highway traffic policemen had poor emergency treatment knowledge.They should be trained with first aid knowledge and skills as well as cardiopulmonary resuscitation training.

Objective To study the value of zoledronic acid combined with psychological intervention in osteoporotic vertebral compression fractures in percutaneous balloon kyphoplasty (PKP). Methods 72 patients with osteoporotic vertebral fractures underwent PKP operation from August 2013 to August 2015 were randomly divided into observation group and control group,with 36 cases,in each group. The patients in the control group were given salmon calcitonin after operation. The patients in the observation group were given zoledronic acid after operation. Both patients were given psychological care. The total effective rate of clinical treatment and the incidence of secondary osteoporotic vertebral compression fractures,Visual analogue pain scale before and after treatment (VAS), Oswestry dysfunction index questionnaire (ODI) score, bone mineral density T value changes were compared between the two groups. Results The total effective rate was 94.44% in the observation group and 77.78% in the control group (P<0.05). The recurrence fracture rate was significantly lower than that of the control group (P<0.05). After treatment, the scores of VAS and ODI in the observation group were significantly lower than those in the control group (P<0.05). The T value of bone mineral density was significantly higher than that of the control group (P<0.05). Conclusion Zoledronic acid combined with psychological intervention can effectively improve the effective rate of PKP after osteoporotic vertebral compression fractures, increase bone density and reduce the incidence of fracture, which is worthy of clinical application.

The promyelocytic leukemia (PML) protein is an important part of the PML nuclear bodies (PML-NBs) structure.PML protein is crucial for the assembly of PML-NBs and recruits more than 30 different proteins, including DAXX, ATRX, and small ubiquitin-like molecules involving SUMO to the PML-NBs region.Increased evidence has emerged that a number of different proteins is involved in regulating PML activities by post-translational modifications, such as SUMO modification, ubiquitination and phosphorylation.Here, we review recent studies on the combination of PML and different proteins in the process of apoptosis, replicative senescence and DNA damage response.
