Insomnia is one of the most common sleep disorders among children and adolescents.Poor sleep affects cognitive performance and is associated with poor emotional and physical health in children and adolescents.Early identification and treatment can have positive short-and long-term effects on the children,the parents,and the family as a whole.Pediatric sleep medicine had sustained development in recent years,however,in China,the researches on the epidemiology,diagnosis and treatment of insomnia in children and adolescents are in lack.In order to capture the majority of pediatric medical workers and parents attention,and to improve the clinical diagnosis and treatment level,the focuses on current diagnosis,therapy and related study progress of insomnia in children and adolescents were reviewed.

OBJECTIVETo observe improved effects of Jingjin acupuncture on fine activity of hemiplegic hand in recovery period of stroke.

METHODSFifty cases were randomly divided into an observation group and a control group, 25 cases in each one. Regular western medicine treatment, rehabilitation training and regular acupuncture (in which Shuigou (GV 26), Baihui (GV 20), Neiguan (PC 6), etc. were selected) were applied in both groups. Additionally, muscles in palm side of affected hand, dorsal metacarpophalangeal joints and proximal interphalangeal joints were treated with acupuncture in the observation group, once every other day and electroacupuncture was applied when arrival of qi was acquired. Baxie (EX-UE 9) in the affected hand were needled in the control group, and electroacupuncture was added when arrival of qi was acquired. Ten days of treatment was considered a treatment course, and after two courses Lindmark score, Brunnstrom movement function grade, joint range of hand and Barthel index (BI) were observed in two groups.

RESULTSCompared before the treatment, the Lindmark score in two groups were both improved after the treatment (both P < 0.01). Compared with the control group, the motor coordination ability, sensory function and total score of Lindmark in observation group were obviously improved (differences before and after treatment: 8.24 +/- 3.07 vs 6.84 +/- 2.43, 3.52 +/- 2.33 vs 2.16 +/- 2.12, 11.76 +/- 3.55 vs 9.00 +/- 3.62, all P < 0.05). The Brunnstrom movement function grade was significantly improved in both groups after treatment (both P < 0.01), which was more obvious in the observation group (P < 0.05). The joint range of hemiplegic hand was improved in both groups after treatment (both P < 0.01), which was more obvious in the observation group [differences before and after treatment: (25.35 +/- 10.91) degrees vs (18.65 +/- 7.86) degrees, p < 0.05]. The score of BI was also significantly improved after treatment in two groups (both P < 0.01).

CONCLUSIONThe Jingjin acupuncture could effectively improve fine activity of hemiplegic hand in recovery period of stroke prove daily life ability.

OBJECTIVETo explore the onset cycle of scarlet fever in Beijing and its association with theory of five evolutive phases and six climatic factors (FEPSCF).

METHODSBased on the monthly scarlet fever data from 1970 to 2004, Complex Morlet wavelet was adopted to analyze the annual incidence and the incidence of six climatic factors in the past 35 years. Its association with the cycles of FEP-SCF was explored. The features of heavenly stems and earthly branches in the year that the wave peak corresponded and their correlations with doctrine of FEPSCF were analyzed.

RESULTSThe annual incidence of scarlet fever and the incidence of FEPSCF had two main cycles, i.e., 5 years and 28 years. The 5-year primary cycle was consistent with 5-year cycle of FEPSCF theory. The high incidence year of 5-year primary cycle was Jinyun.

CONCLUSIONSThe cycle of five evolutive phases was consistent with the onset cycle of scarlet fever. The quasi-periodic phenomenon and multi-cycle superimposed phenomenon of FEPSCF theory existed in the incidence of scarlet fever.

Objective To investigate the distribution status of coal-burning fluorosis (endemic fluorosis) areas in Luoyang and to provide scientifc evidence for making strategies in prevention and control. Methods In 2006, a household per village was chosen to carry the general survey so as of disease condition, living habits and housing structure among 941 coal-burning pollution fluorine sickness natural villages in Yanshi, Mengjin, Xin'an, Luanchuan counties and Geely area which were under the jurisdiction of Luoyang. In the general survey, the sampled village having a population of more than 500 person was considered as a major survey village, and water fluoride, 8 - 12 year-old child fluorine spot on tooth and the urinary fluoride were surveyed. Water fluoride and the child urinary fluoride determination used the fluoride ion selective electrode method, and the children's dental fluorosis used Dean method. Results The endemic fluorosis of Luoyang existed 742 in endemic fluomsis villages, compared with history, a decrease of 199 in number. Ninety-six point seven per cent( 142 543/147 419) of the households were consuming smoke-free coal. Households using intact kitchens accounted for 93.6%( 137 919/147 419). Of which 63.0%(86 889/137 919) of kitchens were mixed up with bedrooms. Total 125 060 people were using coal- fired furnace for heating, of which 87.8%(109 802/125 060) had smoke-free facilities, 12.2%(15 258/125 060) had none. Among 52 endemic villages with population of more than 500 people surveyed, a total of 183 water samples were collected, 2 had water fluoride exceeding 1.0 rag/L, the highest water fluoride being 1.04 rag/L, averaging 0.39 mg/L Sixteen villages had a prevalence rate of dental fluorosis for children less than 30.00%, accounting for 30.8% (16/52), 36 endemic villages the prevalence of dental fluorosis detection rate of more than 30.00%, accounting for 69.2%(36/52). Twenty-thrce villages had a dental fluorosis index greater than 0.6, severe dental fluorosis was not found. Real-time measurement of 1408 urine samples of children aged 8 - 12 showed that urine fluoride highest value 6.88 nag/L, the minimum value of 0.10 mg/L, geometric mean 1.10 mg/L. The prevalence rate of dental fluorosis for children was 36.06%. Conclusions In Luoyang city, numbers of coal-burning endemic fluorosis villages are less than before, children's dental fluorosis has significantly declined, however some people still use kitchens connecting with bedrooms and lack smoke-free facilities, they need to be educated to change lifestyle and improve furnace to reduce soot fluoride pollution.

OBJECTIVETo explore the relationship between genetic polymorphisms in methylenetetrahydrofolate reductase (MTHFR), methionine synthase reductase (MTRR), the central enzymes in folate metabolism that affects DNA methylation and synthesis, and the risk of Down syndrome in China.

METHODSGenomic DNA was isolated from the peripheral lymphocytes of 64 mothers of children with Down syndrome and 70 age matched control subjects. Polymerase chain reaction and restriction fragment length polymorphism were used to examine the polymorphisms of MTHFR 677C-->T, MTRR 66A-->G and the relationship between these genotypes and the risk of Down syndrome was analyzed.

RESULTSThe results show that the MTHFR 677C-->T polymorphism is more prevalent among mothers of children with Down syndrome than among control mothers, with an odds ratio of 3.78 (95% confidence interval (CI), 1.78 approximately 8.47). In addition, the homozygous MTRR 66A-->G polymorphism was independently associated with a 5.2-fold increase in estimated risk (95% CI, 1.90 approximately 14.22). The combined presence of both polymorphisms was associated with a greater risk of Down syndrome than the presence of either alone, with an odds ratio of 6.0 (95% CI, 2.058 approximately 17.496). The two polymorphisms appear to act without a multiplicative interaction.

CONCLUSIONMTHFR and MTRR gene mutation alleles are related to Down syndrome, and CT, TT and GG gene mutation types increase the risk of Down syndrome.
