Objective To study the changes and clinical significance of serum kalium,natrium,chlorine,calcium and glucose in children with febrile convulsion(FC).Methods Serum kalium,natrium,chlorine,calcium and glucose concentrations were measured in 41 children with FC(FC group),30 children with fever and without convulsion(fever group) and 30 normal children(normal group) by automatic biochemical detector.Results Serum kalium and calcium concentrations had no significant difference between FC group and fever group,but they were significantly lower than those of normal group(F=5.965,3.048 P0.05).Conclusions There are hyponatremia,hyperglycemia and lowered blood kalium and calcium in patients with FC.Hence,while treating the patient with FC,the disturbance of blood electrolytes and glucose need be corrected to avoid the recurrence of FC and the progressive injury of important organs such as brain.

Objective To observe the changes of water, potassium and sodium in the hypoxic cerebral tissues in mice and the effects of progesterone on the tissues and investigate the neuroprotective role of progesterone (PROG)in the cerebral anoxia. Methods Thirty - two male mice were divided into control group, simple hypoxia group, lower dosage group and higher dosage group. Progesterone was injected intraperitoneally in the dosage of 4 mg/kg or 8 mg/kg respectively 30 min before hypoxia in the last two groups. The contents of water, potassium and sodium in brain tissues in mice were evaluated at 24 hours after cerebral anoxia. Results The water, potassium and sodium contents in simple hypoxia group were significantly higher than those in control group(P0.05)in higher dosage group(8 mg/kg PROG)compared with those of simple hypoxia group. Conclusions At 24 hours after cerebral anoxia, there are significant increases of water, potassium and sodium in brain tissues. Progesterone may pro-duce neuroprotective role by inbibiting the rise of them.

Objective To explore the relationship between reduction of regional cerebral blood flow in the normal appearing white matter (NAWM) and the extent of age-related white matter lesions (WML).Methods We used Fazekas scale to divide all participants into four groups (normal,mild,moderate,severe) according to the extent of the lesions showed on MRI.Regional cerebral blood flow (rCBF) in the area of WML and NAWM was measured by xenon contrast CT examination.Results A total of 56 cases were selected.The average rCBF (ml · 100 g-1 · min-1) in the lesions (WML) around ventricle,in right centrum ovale and in left centrum ovale respectively was 20.33 ± 2.52,21.27 ± 1.02,21.03 ± 1.83 for mild; 16.33 ±2.03,15.55 ±1.71,15.91 ±0.98 for moderate; 14.05 ±2.63,14.46 ±2.17,14.23 ± 1.95 for severe.The average rCBF (ml · 100 g-1 · min-1) in the NAWM around ventricle,in right centrum ovale and in left centrum ovale respectively was 20.79 ± 2.78,22.26 ± 1.9,22.15 ± 2.4 for normal; 21.12 ± 2.95,22.17 ± 1.50,22.25 ± 2.13 for mild,18.02 ± 2.41,19.45 ± 1.94,19.62 ± 1.54for moderate; 16.38 ± 3.22,18.18 ± 2.84,16.74 ± 2.97 for severe.The decrease of rCBF in the severe and moderate lesion areas was more serious than that in the mild lesion areas and reached statistic significance (P ＜ 0.05) ; The decrease of rCBF in the severe and moderate lesion areas was more serious than that in the area of NAWM in the same grade and reached statistic significance (P ＜ 0.05).The decrease of rCBF in the area of NAWM around severe and moderate lesion areas was more serious compared with that around mild lesion areas or normal areas (P ＜ 0.05) ; But the difference of rCBF in the area of NAWM around mild lesion areas and normal areas did not show any statistic significance.Conclusions Chronic ischemia was found to be existed not only in the lesions (WML) but also in the area of NAWM around the lesions,and was related to the extent of the lesions.Chronic ischemia may play a key role in the mechanism of aged-related WML.

Objective To reduce the misdiagnosis of the inpatients admitted to digest department with abdominal pain through analyzing the consultation undertaken by surgeon.Method The causes and the constituent ratio according to the case records of those inpatients admitted to digest department because of abdominal pain were analyzed.Results The obstruction of hollow viscus was the first cauge(51.07%),and the tumor of digestive tract(17.78%)was the second cause for invitation for consultation to surgeon of the inpatients with abdominal pain in digest department wards.The ultrasound 32.78%,CT 26.67% and gastroenterological endoscope 13.89% were definite diagnosis,and should shorten the time of consultation.Conclusion Whether inpatient or outpatient with abdominal pain should be planned to be examined by ultrasound,CT or gastroenterological endoscope,obgerve the changes of the symptom and sign so that the misdiagnosis can be avoided.

OBJECTIVE To evaluate the roles of p15,p27 gene protein and expression in nasopharyngeal carcinoma(NPC).METHODS The EnVision immunohistochemical method was used to detect the expression of p15,p27 gene protein in nasopharyngeal carcinoma tissues of 43 NPC cases and non-tumor nasopharyngeal tissues of 21 cases.RESULTS ① The positive expression rates of p15,p27 gene protein were 65%,68% in NPC respectively.There were significant differences between NPC and non-tumor group(P0.05).③The positive expression of p15 gene protein was correlated to the positive expression of p27 gene protein(P

Objective:To systematically evaluate the therapeutic efficacy of tuina therapy for primary insomnia.Methods:Nine Chinese and English databases were searched from the inception to May 2017 to identify randomized controlled trials (RCTs) studying tuina therapy for insomnia.The enrolled articles were all RCTs with tuina as the monotherapy or major therapy in the experiment group,with clear diagnostic criteria for primary insomnia well recognized worldwide or in China,and Pittsburgh sleep quality index (PSQ I) as one of the outcome measures.Two researchers evaluated the risk of bias and quality of the enrolled studies by following Cochrane Handbook version 5.1.0.The meta-analysis was performed by RevMan version 5.3.Results:Eleven studies were included with a total of 1 076 participants.The Western medication adopted in the control groups were benzodiazepine receptor agonists.The studies were all assessed as high risk of bias for blinding since blinding method was unable to be performed due to the specificity of tuina therapy;no study reported the support of fund or potential interest conflict,so they were all rated unclear for selective reporting.The meta-analysis showed that compared with other traditional Chinese medicine therapies,tuina worked more effectively in reducing the PSQI score (MD=-4.11＜0,95％ confidence interval (CI)-6.01 to-2.22,P＜0.0001);compared with oral administration of Western medication,tuina showed more significant efficacy in reducing the PSQI score (MD=-3.42＜0,95％CI-5.19 to-1.66,P＜0.0001).Subgroup analysis showed that head tuina alone showed no significant difference compared with oral administration of Western medication regarding the change of PSQI score (MD=-4.19＜0,95％CI-8.87 to 0.50,P＞0.05);a combination of head and back tuina could more effectively reduce the PSQI score compared with oral administration of Western medication (MD=-2.08＜0,95％CI-3.09 to-1.06,P＜0.0001).Conclusion:Tuina can produce more significant efficacy in treating primary insomnia compared with other traditional Chinese medicine therapies and oral administration of Western medication,especially the combination of head and back tuina.
