Objective To observe the clinical efficacy of acupuncture at the three tongue points plus tuina in treating hypersalivation in cerebral palsy.Method Sixty patients with hypersalivation due to cerebral palsy were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened predominantly by acupuncture at the three tongue points plus tuina, while the control group was by tuina alone. The clinical efficacies were compared between the two groups.Result The total effective rate was 96.7% in the treatment group versus 83.3% in the control group, and the difference was statistically significant (P<0.05).Conclusion Acupuncture at the three tongue points plus tuina is an effective approach in treating hypersalivation in cerebral palsy.

Background Refractive surgery has propelled itself forward to become widely performed surgical procedure nowadays.After the surgery,corneal biomechanics decreases lead to keratoconus and corneal ectasia.Doctors pay more attention to biomechanics changes after refractive surgeries.Objective This clinical study was to investigate the influence of different laser refractive surgeries on corneal biomechanics.Methods A prospective nonrandomized and controlled clinical study was designed.One hundred and sixty-four eyes of 82 patients with moderate myopia were enrolled.The patients were divided into sub-Bowman keratomileusis (SBK) group (60 eyes of 30 patients),laser in situ keratomileusis (LASIK) group (54 eyes of 27 patients) and laser subepithelial keratomileusis (LASEK) group (50 eyes of 25 patients),with the matched demography among the three groups.Corneal hysteresis (CH) and corneal resistance factor (CRF) were detected by ocular response analyzer (ORA) before and 1 week,5 months after refractive surgery.The correlations between stromal ablation depth and postoperative changing values of CH or CRF were analyzed.Results Significant differences were found in CH and CRF at different time points in the three groups (Ftime =41.90,P =0.00;Ftime =49.65,P =0.00),and the CH and CRF values were significantly lower 1 week and 5 months after surgery than those before surgery (all at P =0.00).However,no significant difference of CH or CRF was seen at all time points among the three groups (Fgroup =2.17,P =0.08;Fsroup =2.67,P =0.07).No correlation was found between corneal ablation depth and CH in 1 week and 5 months after surgery (both at R2 =0.000),however,weaker correlations were seen between corneal ablation depth and CRF 1 week and5 months after surgery (Y=3.253+ 0.010X,R2=0.007;Y=1.073+0.021 X,R2=0.004).Conclusions SBK,LASIK and LASEK lead to the change of corneal biomechanics by altering CH and CRF,they play the same influence on cornea.CRF appears to be an useful indicator in evaluating corneal biomechanical changes after laser refractive surgery.

Objective To investigate the corelation between platelet activating factor acetylhydrolase (PAF-AH) genetic polymorphism and ischemic stroke. Methods The plasma PAF-AH genotype was determined in 205 patients with iachemic stroke and 114 normal subjects by the polymerase chain reaction. The levels of plasma platelet activating factor (PAF), platelet α-granule membrane glycoprotein-140(GMP-140), β-thromboglobulin (β-TG) and the levels of platelet factor 4 (PF4) were analyzed. Results The prevalence of the mutation genotype and plasma PAF, GMP-140, β-TG and PF4 in the patients with isehemic stroke [42.44%,(91.08 ± 39.10) ng/L, (36.46 ± 13.10) μg/L, (41.75 ± 11.18) μg/L, (29.05 ± 9.16) g/L, respectively] were significantly higher than those in the controls[21.05%,(64.30 ± 18.81) ng/L, (18.27 ± 7.68) μg/L, (30.94 ± 8.47) μg/L, (18.75 ± 6.06) μg/L](P< 0.01). The levels of plasma PAF, GMP-140 were significantly higher in mutation genotype patients than those in the normal genotype patients (P < 0.01). Conclusions The activation function of platelet in the acute phase of patients with ischemic stroke increases, and it is associated with genetic polymorphism of PAF-AH. The PAF-AH gene mutation may be a novel genetic marker for high risk of ischemic stroke.

Objective To investigate the relationship between low serum calcium concentration and hematoma volume in patients with intracerebral hemorrhage.Methods Between January 2012 and October 2014,870 consecutive patients with intracerebral hemorrhage admitted to the Department of Neurosurgery,West China Hospital,Sichuan University were enrolled prospectively.The patients completed laboratory serum calcium concentration and head CT examinations within 24 h after attack,and the baseline data and laboratory findings were collected.According to the normal reference value of laboratory serum calcium concentration,the patients were divided into a hypocalcemia calcium group (<2.1 mmol/L;n=193) and a normal calcium group (2.1-2.7 mmol/L;n=677).Spearman correlation analysis was used to analyze the correlation between the blood serum calcium concentration and the hematoma volume on admission.Results (1) The hypocalcemia group compared with normal calcium group,the proportion of male patients was high (73.6% [n=142] vs.66.0% [n=447]),the median score for Glasgow coma scale was lower (9 vs.11),and the median hematoma volume was larger (33.86 cm3 vs.21.69 cm3).The differences were statistically significant (all P<0.05).(2) Spearman correlation analysis showed that the lower serum calcium level on admission was weakly negatively correlated with the volume of hematoma in patients with intracerebral hemorrhage (r=-0.113,P<0.01).Conclusion The study suggested that the hypocalcemia on admission was mostly males in patients with intracerebral hemorrhage,the condition was serious,the volume of hematoma was larger,and the lower serum calcium concentration was negatively correlated with the hematoma volume.

Paeoniflorin is the main active ingredient of Chinese herbaceous peony. This study is to investigate the protective effect of paeoniflorin (Pae) on acute brain damage induced by lipopolysaccharide (LPS) in mice. The mice were randomly assigned to the normal control, model control (LPS), as well as groups of paeoniflorin and lipopolysaccharide (Pae + LPS). Then the mice were administered intraperitioneally with normal saline or Pae (10, 30 mg · kg(-1)) once daily for 6 d. One hour after intrapertioneally treatment on the seventh day, each group were injected LPS (5 mg · kg(-1)) to establish the endotoxin lipopolysaccharide inflammation model except the normal group. The mice were sacrificed after 6 h and the brain homogenates were prepared and measured. The malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), total antioxidant capacity (T-AOC), hydrogen peroxide (H2O2), succinatedehydrogenase (SDH), Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase were dectected by the colorimetric method. The levels of HO-1 and Nrf2 protein in subcellular fractions of brain tissue were detected by Western blot. The results demonstrated that the administration with paeoniflorin reduced the levels of the MDA production; significantly increase the activities of antioxidant enzyme (SOD and GSH-PX). In addition, paeoniflorin could enhance the total antioxidant capacity, decrease the level of H2O2, and increase the activities of SDH, Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase. Furthermore, paeoniflorin can increase the expression of HO-1 and activate the nuclear transfer of Nrf2. Taking together, these findings suggest that paeoniflorin alleviate the acute inflammation in mice brain damage induced by LPS, which is related with its antioxidant effect and improvement of energy metabolism.

Cell culture plays an important role in virology. It provides a platform for the detection and isolation of viruses as well as for the biochemistry and molecular biology based studies of viruses. In the present work, a new system that could permits multiple (different) cell lines to be simultaneously cultured in one dish was developed. In the system, each cell line was cultured in an isolated zone in the same dish or well and the system is therefore called an isolated co-culture system. The usefulness of this novel approach for virus isolation was demonstrated using a model system based on adenovirus.

Objective:To explore the utilization of and satisfaction at community health service between migrant and non-migrant workers in Shenzhen city. Methods: Random sampling was used and 8000 community residents in Shenzhen city were investigated, and the data was analyzed with SPSS 18. 0. Results:There was statistically signifi-cant difference on the times of seeking community health services last year between migrant workers and non-migrant workers ( P<0. 0001 ) , and the proportion of more than three times service utilization of migrant workers were greater than that of non-migrant workers. The top three elements inpluencing satisfaction at community health service between migrant and non-migrant workers were service attitude ( 73. 29% vs. 73. 46%) , technical level ( 65. 29% vs. 67. 50%), and its convenience of seeking a doctor (63. 16% vs. 64. 98%). 73. 47% of users (migrant workers:74. 16%, non-migrant workers:69. 71%) were willing to accept the system of first contact in community health in-stitutions. Conclusions:The utilization of community health service has increased since implementing the system of first contact in community health institutions. Both migrant workers and non-migrant workers were very satisfied with the community health services, and the differences on satisfaction between the two groups were not significant. It is feasible to gradually promote the system of first contact in community health institutions over China.

6.2 mmol/L) who underwent renal transplantation accepted pravastatin therapy 10 mg once evening for 8 weeks. Total cholesterol(TC),low-density lipoprotein-cholesterol (LDL-C),high-density lipoprotein-cholesterol (HDL-C),triglyceride(TG),endothelin(ET) and nitrous oxide(NO) were measured before and after pravastatin therapy. The endothelium-dependent relaxing function was measured before and post pravastatin therapy by high-resolution ultrasound. Thirty people with normal blood cholesterol accepted same examination as control. Results The level of ET in renal transplantation group was significantly higher than that of control group,and the level of NO in renal transplantation group was significantly lower than that of control group. After 8 week′s therapy,the level of NO rose significantly,and the level of ET,TC,LDL-C,TG decreased significantly. The level of HDL-C increased but there was no significant difference between two groups. Flow-mediated vasodilations were improved after pravastatin therapy,while the level in transplantation group was lower than that of control group. Conclusion Pravastatin is effective in treatment of dyslipidemia after renal transplantation,which can improve the endothelium-dependent vasodilation.
