Objective To investigate the features of the cerebrospinal fluid (CSF) in the modified ZeiM-Neelsen (MZN) positive tuberculous mengningitis (TBM).Methods We retrospectively reviewed the clinical data of 170 patients with tuberculous meningitis confirmed by MZN stain from December 2012 to July 2015.The purpose of the present study was to investigate the relationship of MZN staining and CSF cytology.Results Among 170 patients with TBM confirmed by MZN staining,128 cases had first detectable acid-fast bacillus (AFB) in earlier stage.The cytology included 15.5％ mixed cellular cytology,58.5％ lymphoid cytology,19.5％ neutrophilic cytology and 6.5％ normal cytology.Twenty-four cases had first detectable AFB within 1-2 months following disease onset.The cytology included 13.1％ mixed cellular cytology,56.6％ lymphoid cytology,21.7％ neutrophilic cytology and 8.7％ normal cytology.Eighteen cases had first detectable AFB 2 months after disease onset.The cytology included 26.7％ mixed cellular cytology,46.7％ lymphoid cytology,20.0％ neutrophilic cytology,6.6％ normal cytology.There was no significant difference in median time of first detectable AFB among those four types of cytology (P=0.812).There was significant difference in median time of first detectable AFB between patients with and without anti-TB therapy [21.5 (12.3,37.8) days vs.8.5 (6.0,16.3)days,P＜0.001].There was no significant difference in median time MZN stain turning negative between patients with and without anti-TB therapy [11 (5.75,19.25) days vs.6(4.25,10.75)days,P=0.230].Conclusions AFB can be detectable within a month after the onset of TBM in most of cases.(MZN) positive staining is not associated with the major type of cytology.Anti-TB therapy may delay the first detectable time of AFB.

BACKGROUND: Stroke in progression(SIP) accounts for 26% -43% of cerebral infarction. It is a common clinical stroke subtype. However, there are no effective treatments to stop the progress with higher mortality rate and invalid rate. More attentions have been paid for multiple risk factors of cerebrovascular diseases during precaution and treatment. But the study on relationship between infection and stroke occurrence, and the inhibited clinical event with antivirus druggery is just at the beginning.OBJECTIVE: To investigate the correlation between clinical SIP characteristics and herpes virus(HSV) infection, and provide the clues to the SIP diagnosis and treatment and early rehabilitation.DESIGN: Case-control study based on patients.SETTING: Department of neurology in a university hospital and a microbiological department in a university.PARTICIPANTS: Totally 47 patients with progressive stroke hospitalized in Department of Neurology, the Second Hospital of Hebei Medical University during April 2001 to March 2002[21 males, 26 females; aged from 15 to 78 years, mean age of(53.12 ± 2.45) years] . There were 43 cases of limb paralysis (92%), 7 cases of aphasia, 4 cases of consciousness disturbance, 1 case of epileptic seizure, 1 case of hemianopia, 5 cases of ataxia, and 24 cases of dizziness. The diagnosis of cerebral infarction was confirmed with CT and/or MRI. The patients clinical pregresively aggravated over more than 72 hours from the stroke onset. And it was not able to stop the aggravation of the situation with conventional treatment. The patients with embolism and reversible ischemic neurological deficit(RIND), cerebral hemorrhage, hemorrhagic infarct were excluded; Patients with other severe diseases such as coronary heart disease, cardiac atrium fibrillation, severe diabetes, hypertension, and the history of illness more than 5 years were excluded. Totally 193 patients were selected as control group with non-cerebrovascular disease, included headache, insomnia, neck and shoulder pain[ 100 males, 93 females, aged from 26 to 60 years,mean age of(42.23 ±9.29)].of the Fourth Scholarship Meeting of Cerebrovascular Diseases in China in tected by MRI, 44 cases detected by magnetic resonance angiography(MRA), 4cases detected by digital subtraction angiography (DSA), and 8 cases detected levels of IgM of human cytomegalovirus(HCMV) and herpes virus(HSV) in serum of 47 patients with progressive stroke and 193 patients without cerebrovascular disease were detected by dot immunogold labeling staining (IGLS); Stromatin PP65 antigen of HCMV in marrow cell were detecting by of the situation with the conventional treatment. PFA 250 mL(3.0 g) was given once a day from 14 to 21 days and dexamethasone 5 - 10 mga day for 3 to 7 days.after treatment with antivirus druggery.dot low-density plaques in cortex or subcortex of cerebral lobes, were found in were found positive in 91% of the patients and the level of IgM in patients PFA was effective.of cerebral lobes, and stenosis or occlusion in cerebral arteries or major infection and progressive stroke.

Aim To study the in vitro and in vivo an-tioxidant activity of Inula nervosa wall. in order to le-gitimately use the resources of I. nervosa. Methods The medicinal ingredients of aboveground and under-ground parts of I. nervosa were extracted by different extraction methods. Ultrasonic extractions from differ-ent parts were compared by their in vitro and in vivo antioxidant effects. Results Ultrasound alcohol ex-traction had the highest content of total phenols and fla-vonoids, with the content of total phenolics much high-er than that of total flavonoids. Ultrasound alcohol ex-tractions had very good scavenging effect on DPPH, ABTS and superoxide anion radical, with the extraction from underground part more effective than extraction from aboveground part. Ultrasound alcohol extractions significantly increased the level of catalase ( CAT), superoxide dismutase (SOD), total antioxidant capaci-ty (T-AOC), glutathione peroxidase (GSH-Px) activi-ty and decreased the level of malondialdehyde (MDA) in liver, kidney and serum in drenching aging mice. The antioxidant activity of high concentration of the ex-traction from aerial part was equivalent to that of low concentration of the extraction from underground part. Conclusions Ultrasound alcohol extractions of I. ner-vosa have very good scavenging effect on free radicals, which indicates good antioxidant ability. Antioxidant activity of underground part is much stronger than that of the aboveground part.

Objective To investigate the role of S100B protein in the pathogenesis of patients with Japanese encephalitis (JE).Methods A total of 45 patients were enrolled in the Second Hospital of Hebei Medical University from August 2013 to October 2013,who were diagnosed as JE on the basis of clinical features and positive IgM antibodies against JE virus measured by enzyme-linked immunosorbent assay (ELISA) from the Center of Disease Control of Shijiazhuang.The JE patients were divided into initial phase group,acute phase group and convalescence group based on the course,mild JE group,moderate JE group and severe JE group based on the severity,MRI-no-lesion group and MRI lesions group based on the imaging findings of JE.Twelve cases with no evidence of infection in central nervous system in the meantime were chosen as control.The S100B protein was measured by ELISA.Results The content of S100B protein in cerebrospinal fluid was as follows:522.76 (393.35,620.37) pg/ml in mild JE group (acute phase group:609.77 (549.27,779.71) pg/ml,convalescence group:420.48 (344.36,453.19) pg/ml),792.09 (705.47,1 108.96) pg/ml in moderate JE group (acute phase group:770.19 (646.31,1 069.54) pg/ml,convalescence group:803.45 (602.90,1 396.84) pg/ml),and 1 021.94 (680.84,1 302.15) pg/ml in severe JE group (acute phase group:981.82 (680.84,1 826.28) pg/ml,convalescence group:989.00 (553.62,1 207.67) pg/ml).The S100B protein content was 561.52 (454.36,814.56) pg/ml,803.45 (602.90,1 104.01) pg/ml,762.22 (594.95,1 044.97) pg/ml,581.76 (442.51,1 069.10) pg/ml in MRI-no-lesion group,MRI lesions group,total acute phase group and total convalescence group,respectively.While in control group,the S100B protein content was 266.71 (205.72,390.05) pg/ml.The contents of S100B protein in moderate JE group,severe JE group,total acute phase group,total convalescence group,MRI-no-lesion group,MRI lesions group were higher than that in control group (H =4.864,5.497,5.075,3.918,2.971,4.981,P =0.000,0.000,0.000,0.000,0.009,0.000).The contents of S100B protein in mild JE group was lower than that in moderate JE group and severe JE group (H =-2.786,-3.514,P =0.032,0.003).Conclusions The level of S100B protein in cerebrospinal fluid is related with the severity,duration and imaging presentation of JE patients.The dynamic monitoring of S100B protein levels is of great significance for assessment of the patients' condition and curative effect.

Objective To explore somatic symptoms of patients with functional dyspepsia (FD) and effects of combined anti somatisation therapy on the quality of life in patients with FD.Methods Two hundred and nineteen patients with FD were enrolled.Patient Health Questionnaire-15 (PHQ-15) and Nepean Dyspepsia Index (NDI) were completed,and the relation between them was analyzed.Lansoprazole,mosapride and flupentixol melitracen (the anti-somatisation medication) were taken for four weeks by 131 FD patients who had poor response to four-week conventional treatment with proton pump inhibitors (PPI) and/or prokinetic medication and who got more than 4 scores in PHQ 15.And then therapeutic effects were observed and the changes of NDI before and after treatment were analyzed.The t test,chi-square test,Spearman's correlation and linear regression were performed for statistical analysis.Results The total PHQ-15 and NDI score of 219 patients with FD were 5.7±3.4 and 42.0± 10.4,and there was positive correlation between them (r=0.493,P＜0.05).Stomach pain,headache,chest pain,dizziness,shortness of breath,fatigue,sleeping disorder,thirst and so on were positively correlated with totalNDIscore (r=0.262,0.230,0.241,0.243,0.352,0.385,0.266,0.281,all P＜0.05).Chest pain,stomach pain,shortness of breath,dizziness and fatigue were the influence factors of NDI (t=2.340,2.488,5.278,2.167,2.443,all P＜0.05).Among 131 patients with FD who received anti somatisation combination therapy,six patients did not complete the therapy because of the side effects,and finally 125 patients were enrolled and analyzed.Before and four weeks after the treatment,the total PHQ-15 scores of 125 patients with FD were 7.3±3.2 and 2.9±2.2,respectively; and the difference was statistically significant (t =12.653,P＜0.01).There were significant differences in the influence of stomach pain,headache,chest pain,dizziness,shortness of breath,fatigue,sleeping disorder and thirst before and after the treatment (not bothered at all,bothered a little,bothered a lot) (x2=39.231,6.796,6.693,15.520,6.698,51.572,44.390 and 16.506,all P＜0.05).The total NDI score before and after the treatment were 44.3 ± 11.7 and 29.2 ± 6.9,and the difference was statistically significant (t=12.503,P＜0.01).Conclusions The quality of life in patients with FD is affected by somatic symptoms such as chest pain,stomach pain,shortness of breath,dizziness,fatigue and so on.For FD patients with poor response to conventional treatment,the quality of life could be improved by the combination of anti-somatisation therapy and the conventional therapy.

OBJECTIVE: To study the antibacterial activity of meropenem in vitro and the pharmacokinetics of which in patients with burn injury. METHODS: The minimal inhibition concentration (MIC) of meropenem against 136 clinical isolates was determined with double agar dilution method. 28 patients with burn injury were given 0.5g of meropenem by iv gtt, with the blood concentration of meropenem and the recovery of meropenem in urine were determined at different time. The pharmacokinetics parameters were computed with 3p97 software. RESULTS: Meropenem showed a strong antibacterial activity against K.peneumoniae, pneumonococcus and Enterobacter cloacae. MIC90 was below 0.0 075～0.25?g/ml. Pharmacokinetics parameters of meropenem were the following: t1/2? was (0.35?0.12) h,t1/2? was (2.10?0.71) h,AUC was (44.62?12.95) ?g/ml,Vc was (10.60?3.93) L; CLs was (12.00?3.04) L/h. 6.5 hours later, the mean blood concentration was (1.01?0.53)?g/ml; and the recovery of meropenem in 0h～12h urine was (58.06?16.83) %. CONCLUSIONS: Meropenem showed a very strong antibacterial activity in this study,there were significant differences regarding the in vivo pharmacokinetics parameters between the healthy volunteers and the patients with burn injury.

Objective To investigate the malaria knowledge of CDC staff and their demands on related training in malaria non⁃endemic areas，so as to provide the reference for planning the appropriate curriculum. Methods All the participants who were the staff of county CDCs all over Qinghai Province and attended the provincial training workshop were surveyed. A self⁃administered questionnaire survey was carried out and the data was statistically analyzed. Results A total of 115 participants were involved in this survey. They were mostly（85.21%）from county CDCs. The general knowledge of malaria among the respondents was well，and the average rate of correct answers was 70.35%. However，the answers to the general knowledge of malaria and anti⁃malaria treatment were not well enough. The rates of correct answers were 61.96% and 48.99% respectively. The differences among the groups of job title ranking，department of working and level of CDC were not significant（F = 0.13-2.02，all P > 0.05）. The number of correct answers was significantly increased after the training course. The average score after the training was 79.20±15.16 while the pre⁃training score was 70.34±17.46（t = 3.86，P < 0.05），especially in the answers to general malaria knowledge and malaria surveillance and response（t = 4.30，4.97，both P < 0.05）. The general knowledge of malaria was considered as the most need of training as 80% of the respondents voted“Yes”，according to the demand analysis. There was no significant difference among the different groups（F = 0.61-3.11，both P > 0.05）. Conclusion The malaria knowledge is well mastered by the staff of CDCs in Qinghai Province，and the further training courses are requested and addressed in the target areas such as general malaria knowledge，anti⁃malaria treatment，malaria surveillance and response.
