Pediatric sleep-disordered breathing, also known as obstructive sleep apnea and hypopnea syndrome (OSAHS) in children, is caused by obstruction of upper airway, characterized by repetitive pauses in breathing during sleep despite the effort to breathe, and usually leads to reduction in oxygen saturation. Due to the importance of sufficient oxygen in growth and development, many children patients suffer from abnormal secretion of growth hormone at night, and also their activity and resting of cerebral cortex during sleep. Therefore, they face great risks in keeping normal physical growth, forming mental behavior, building up learning ability and shaping personalities. It is a very important interdisciplinary subject, yet still much remains unclear about the disease. Oral medicine is one of the subjects that show increasing importance in prevention and treatment of OSAHS in children. On one hand, due to the special means of the field, such as cephalometric, it can diagnose and monitor the development of craniofacial structures, especially the upper airway. On the other hand, it can provide treatments which can both improve breath during sleep and consequent dental facial deformities. Most typical treatments include mandibular sagittal growth stimulation, transverse maxillary palatal expansion and maxillary protraction. Oral medicine provides additional treatment apart from traditional adenectomy and tonsilectomy to improve ventilation. It not only directly helps to improve deformities caused by sleep-disordered breathing in OSAHS children with indications, but also helps to avoid many of physical and mental complications, which will in turn benefit their life quality. Also, it may prospectively provide insights in treatment and prevention of OSAHS in adults.

Cerebral smal vessel disease (CSVD) refers to various diseases of brain perforating arterioles, capilaries and venules caused syndrome of clinical, cognitive and pathological manifestation. It is not only the main cause of stroke, but also causes cognitive impairment and dementia. Its pathogenesis is not fuly understood. Many studies have confirmed that endothelial dysfunction plays an important role in the pathogenesis of CSVD. This article review s the relationship between endothelial dysfunction and CSVD in order to provide new ideas for etiology, pathogenesis, and clinical prevention and treatment of CSVD.

OBJECTIVE:To provide reference for clinical rational drug use. METHODS:Combined with bacterial drug resis-tance monitoring data in our hospital in 2014,the varieties,the amount of antibacterial drug,DDDs and other index were analyzed retrospectively for the same period. RESULTS:The detection rate of Gram-negative bacteria (79.27%) was higher than that of Gram-positive bacteria (20.73%);the most common Gram-negative bacilli and Gram-positive cocci were Escherichia coli (38.62%) and Staphylococcus aureus (5.22%). Pseudomonas aeruginosa and Stenotrophomonas maltophilia were the most com-mon non-fermentation bacteria;Main Gram positive bacteria were most sensitive to vancomycin,tigecycline and furadantin,etc. Main Gram-negative bacteria were most sensitive to imipenem,ertapenem,etc. Top 3 antibacterial drug in the list of DDDs were Levofloxacin injection,Cefazolin injection,Cefoperazone/sodium sulbactam for injection. CONCLUSIONS:Third generation of cephalosporins are used frequently in our hospital,which is a major cause of ESBLs producing and drug resistance,bacterial drug resistance monitoring and early warning data has played a positive role on guiding reasonable application of antibacterial drug in our hospital.

Objective To explore the clinical efficacy of back acupoint pricking and cupping combined with intense pulsed light in the treatment of acne vulgaris.MethodsTotally 160 cases of acne vulgaris treated in our hospital from July 2014 to August 2015 were selected and randomly divided into observation group and control group, 80 cases in each group. Patients in both groups were treated with intense pulsed light, every two weeks, for 4 times. Patients in the observation group were treated with back acupoint pricking and cupping based on the treatment above, every other day, five times as a treatment session, for two sessions. The treatment efficacy was compared between the two groups.ResultsThe total effective rate in the observation group was 96.25% (77/80), which was significantly higher than 77.50% (62/80) in the control group, with statistical significance (P<0.01). Serum T of the two groups after the treatment decreased significantly when compared with those before the treatment. Serum T in the observation group in patients of the same sex decreased significantly after the treatment compared with those in the control group (P<0.01). Total scores of self-perception, emotion function and Qol-Acne score after treatment in observation group were significantly higher than those in the control group (P<0.01). After 3 months of treatment, the recurrence rate of the effective patients in the observation group was 2.60% (2/77), lower than the control group, which was 16.13% (10/62) with significant difference (P<0.01).Conclusion The clinical efficacy of back acupoints pricking and cupping combined with intense pulsed light in the treatment of acne vulgaris is confirmative, which can effectively reduce androgen levels and improve the life quality of patients, with low recurrence rate.
