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.

Objective To discuss the effect of tetrandrine on endogenous neural stem cell proliferation and differentiation after spinal cord injury in rats. Methods 78 rats were randomly divided into 3 groups: control group(n=36), Tet-treated group(n=36), sham-operated group(n=6). Control group and Tet-treated group were adapted with Allen's combat modeling method. Rats in Tet group were injected Ted with a dosage 22.5 mg/kg in 30 minutes, 24 hours and 48 hours after ASCI, and the same dose of saline was injected into injured group as control .Samples were dissected from the spinal cord injury sites at 1 day, 3 days, 1 week, 2 weeks, 3 weeks, 4 weeks after ASCI, and tested by HE staining for morphology and by immunolfuorescence staining for the expression of BrdU and nestin. Results A little Nestin positive cells and BrdU positive cells were found in control group and Tet-treated group at 1 day after injury. A large number of positive cells were found in both groups at 1 week after injury and reached the peak which lasted for 2 weeks and then decreased gradually. The expression of Nestin positive cells and BrdU positive cells in control group and Tet-treated group were decreased significantly at 4 weeks after injury, but were still more than that in sham operation group. The number of Nestin positive cells and BrdU positive cells in Tet-treated group were more than that in control group at each time point after injury. The expression was higher in Tet-treated group than control group at 1 day, 3 days, 1 week, 2 weeks, 3 weeks after injury and had no difference at 4 weeks after injury. Conclusions Tetrandrine could increase the number of Nestin positive cells, BrdU positive cells and endogenous neural stem cells though improving the microenvironment, and it is beneficial for the recovery of spinal cord injury in rats.

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.

Objectives To investigate the influence of cytomegalovirus infection after kidney transplantation on the recipients and the associated risk factors of cytomegalovirus infection .Methods Data of 892 kidney transplantation recipients from January 2000 to December 2004 in our department were analyzed retrospectively . All the recipients were divided into case group (with cytomegalovirus infection) and control group (without cytomegalovirus infection) . Log-Rank test was used to compare the 1-, 3-, 5-year survival of patients and grafts between two groups . The incidence of complications, the difference of regiment of immunosuppressant and anti-CMV drugs were compared as well . The independent risk factors of cytomegalovirus infection were assessed by Logistic regression analysis . Results One-, 3-, 5-year survival rates of patients in case group were 81 .3%, 72 .8% and 54 .8% respectively, while the patients in control group were 96 .4%,91 .4% and 79 .9% respectively, the prior was significantly lower than the latter (Log-Rank value=49 .62, P＜0 .01) . One-, 3-, 5-year survival rates of grafts in case group were 71 .0%, 66 .2% and 46 .1%, while the grafts in control group were 91 .5%, 86 .6% and 74 .5% respectively, the prior was significantly lower than the latter as well (Log-Rank value=44 .87, P＜0 .01) . The incidence of acute rejection in case group was 24 .9%, while it was 13 .9% in control group, with significant difference between two groups (x2=14 .49, P＜0 .01 ) . Logistic regression showed that acute rejection,mycophenolate mofetil dose more than 2 g, and usage of ATG/ALG or OKT3 were the independent risk factors of cytomegalovirus infection (OR=1 .464, 3 .097 and 2 .837, P＜0 .05 ) . Ganciclovir was the protective factor of cytomegalovirus infection (OR =0 .234, P ＜0 .01) . Conclusions Cytomegalovirus infection decreases the long-term survival of recipients and grafts in kidney transplantation . Acute rejection, high dose of mycophenolate mofetil, and ATG/ALG or OKT3 are the independent risk factors of cytomegalovirus infection . Prophylactic usage of ganciclovir after kidney transplantation can effectively reduce cytomegalovirus infection .

Objective To analyze the characteristics of extra-pulmonary tuberculosis in renal transplant recipients,and discuss its diagnosis and management. Methods From Jan.1991 to Apr.2007,37 cases of post-operational tuberculosis were identified out of the 2333 renal transplantations done in our center.Among them there were 19 cases with extra-pulmonary foci(51%),which involved allograft kidney in 5 cases,meninges in 4 cases,pleura in 4 cases,lymph node in 3 cases,soft issue in 2 cases,larynx,liver,vertebra and intestine in 1 case each.In 3 cases,there were 2 extrapulmonary sites involved at the same time.Most of the cases happened within one year post-transplant (53%).The most common clinical manifestation was fever. Results After anti-tuberculosis therapy,14 cases were cured and 5 were irresponsible and died.Eight cases (42%) experienced acute rejection and 4 cases(21%)had abnormal liver function during the treatment. Conclusions Extra-pulmonary tuberculosis had a high incidence and high mortality in post-renal-transplant population.Therefore,attention should be given to its differential diagnosis in clinical practice.Balancing anti-tuberculosis and anti-rejection therapy is important for this specific population.

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.

Objective To investigate the correct diagnosis and treatment of myeloid and lymophoid neoplasms with eosinophilia and the FIP1L1-PDGFR fusion gene. Methods A case of patient who was diagnosed as myeloid and lymophoid neoplasms with eosinophilia and the FIP1L1-PDGFR fusion gene was reported, and the literature was reviewed. Results The patient was diagnosed as typical T-lymphoblast lymphoma (T-LBL) by the lymph node pathologic diagnosis, while the diagnosis of myeloid and lymophoid neoplasms with eosinophilia and the FIP1L1-PDGFR fusion gene was made correctly by the whole examination and analysis. The patient acquired deep complete remission quickly after taking the low dose of imatinib. Conclusions Myeloid and lymophoid neoplasms with eosinophilia and the FIP1L1-PDGFR fusion gene are a rare hematologic tumor. Though pathological diagnosis is the golden standard for lymphoma, sometimes the other factors should be taken into consideration and make an overall analysis of clinical picture and a correct view of the pathological diagnosis, which could avoid the misdiagnosis and improper treatment.
