Objective To search for the changes of T cells subpopulations and immunoglobulin and their relation-ship in children patients with simple nephrotic syndrome. Design Case-control research. Patients aud Participants 39 patients with simple nephrotic syndrome were divided into two groups:the incipient group and relapse group (6 cases were determined at the incipient and relapse time) .Thereare 28 patients in incipient group, 19 males and 9 females, at the age of 2 to 10 years old. There are20 patients in relapse group, 12 males and 8 females, at the age of 3 to 13 years old. There are 35health children in control group, 21 males and 14 females, 2～13 years old. Interventions T cells subpopulations were determined by indirect immunofluorescence of OKT linesmonoclonal antibodies. The serum IgG was determined by routine simple agar immunodiffusion tests. Results and Conclusions The CD_3~+ and CD_4~+ cells are of no change in the children patients withsimple nephrotic syndrome, and the CD_8~+ and CD_(10)~+ cells are obviously increased, the Values of CD_4~+/CD_8~+ are obviously lower than those in the control qroup, there are no difference between the incipientand relapse groups. The levels of serum IgG were decreased in the 85.3% children patients, IgM were inc-reased in 29.4% of that. The values of CD_4~+/CD_8~+ have positive correlation and negative correlationwith the levels of serum IgG and IgM respectively.

To study the potential effect of Dioscorea nipponica(DN) in intervening peripheral system of rats based on metabolomic analysis. The identification of the potential intervention targets of DN in peripheral system may facilitate its safe application and therapeutic potential exploitation. Totally 20 male SD rats were randomly divided into the blank group and the DN-treated groups, with 10 rates in each group. The DN-treated group was orally administrated with DN extracts once a day for 5 days, with the dose of 80 mg x kg(-1) (equivalent to 15 g crude drug in human), and the blank group was given equal volume of saline once a day for 5 days. Heart, liver, spleen, lung, and kidney tissues and serum samples were collected from each rat 24 h later after the last administration. The ultra-performance liquid chromatography/quadrupole time-of-flight-mass spectrometry based metabolomics was used to investigate the effect of DN in intervening peripheral system of rats. After the treatment with DN, 5 modulated metabolites in heart tissue, 6 in liver tissue, 5 in spleen tissue, 3 in lung tissue, 5 in kidney tissue and 6 in serum sample were identified and considered as the potential intervention targets of DN. Effect of DN in regulating some endogenous metabolites was beneficial for protecting peripheral system, while that in other endogenous metabolites produced potential toxicity to peripheral system. The metabolomic analysis revealed the coexistence of protective and toxic effects of DN on peripheral system, which may be a practical guidance for its safe application and beneficial to the expansion of its application scope.

Objective To know the influence of gastrointestinal decontamination (including gastric lavage and activated charcoal treatment) on prognosis of asymptomatic presentation poisoning patients.Method six hundred and twenty seven asymptomatic presentation poisoning cases through January 1999 to December 2006 were reviewed retrospectively.Duration of ED stay and intubation requiring rate were compared between the intervention group and control group (patients treated only with supportive care),as well as complications associated with gastrointestinal decontamination intervention.Results Statistic analysis reveals no difference between the intervention group and the control group in rate of intubation (6.5 % vs 5.3 %,P=0.51) and emergency care unit admission (28.1% vs 26.6%,P=0.68).Meanwhile duration of ED stay is prolonged profoundly in prevention group [ (11.2?4.7) vs (8.9?5.0),P

OBJECTIVETo observe the effect of Baichanting Compound (BC) on dopamine (DA) in striatum of Parkinson's disease (PD) mice, and to screen the optimal component proportion.

METHODSThe PD model was established in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) induced C57BL/6 mice. By using uniform design, they were intervened by three extracts of BC in different proportions [Acanthopanax senticosus extract (X1): white peony root extract (X2): Uncaria rhynchophylla extract (X3) = 30.00: 34.92: 82.50, 48.00: 19.98: 72.19, 18.00: 44.88: 61.88, 36.00: 29.94: 51.56, 54.00: 15.00: 41.25, 24.00: 39.90: 30.94, 42.00: 24.96: 20.63). Equal volume of 5% carboxymethylcellulose sodium was administered to mice in the model group and the normal group by gastrogavage. All medication was lasted for 20 successive days. The dopamine (DA) content was determined by ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS). Except 10 in the normal group, 20 PD model mice were screened and divided into the model group and the BC group (with the optimal proportion) according to random digit table. BC extract in optimal proportion was administered to mice in the BC group by gastrogavage, while equal volume of 5% carboxymethylcellulose sodium was administered to mice in the model group and the normal group by gastrogavage. All medication was lasted for 20 successive days. Praxiology was observed in each group. DA content in striatum was also detected. Results Compared with the normal group, the DA content in striatum decreased significantly in the model group (P < 0.01), suggesting a successful PD modeling. Compared with the model group, the DA content in striatum increased significantly in 1 and 2 groups (P<0.05). According to results of quadratic polynomial stepwise regression statistics, the regression equation obtained was: Y = 0.265 + 0.026 X 2 - 0.056 X 3 + 0.334 x 10(-3) x X1 x X3 + 0.691 x 10(-3) X X3(2). X3 extract was the main factor influencing the effectiveness (P < 0.01). The optimal proportion of BC was predicted by the regression equation: X1 = 54.00 mg/(kg x d), X2 = 44.88 mg/(kg x d), the X3 = 82.50 mg/(kg x d). The pole climbing time was shortened, times of autonomic activities increased, DA content was elevated, all with statistical difference in BC groups (P < 0.01, P < 0.05).

CONCLUSIONBC could increase DA content in PD model mice with the optimal proportion as 54.00: 44.88: 82.50.

OBJECTIVETo evaluate the accuracy and safety of pedicle screw insertion with the aid of novel patient-specific drill-guide templates in scoliosis cases.

METHODSTen patients with scoliosis were selected to participate in the research (the observation group) from December 2013 to December 2014. The data was obtained from CT scanning, and put into the computer to perform reconstruction of spine, simulation of pedicle screw insertion, and design of patient-specific drill-guide templates with software. The templates were made with rapid prototyping technique. After sterilization, the templates were used to aid the pedicle screw insertion intraoperatively. The blood loss, operation duration, change of creatinine level pre- and post-operation, and complications related to pedicle screw insertion were recorded. The location of pedicle screws were graded so as to evaluate the accuracy. A comparative study was then performed with the data of ten scoliosis cases operated with free-hand method during the same period (control group). There were 5 cases of idiopathic scoliosis and 5 cases of congenital scoliosis in the observation group, including 3 males and 7 females. Their average age was 11.9 years old (ranged, 4 to 18 years old), and the average Cobb angle of main curve was 54.9° (ranged, 42.1° to 78.4°). There were also 5 cases of idiopathic scoliosis and 5 cases of congenital scoliosis in the control group,including 2 males and 8 females. Their average age was 12.6 years old (ranged, 6 to 17 years old), and the average Cobb angle of main curve was 56.6° (ranged, 38.2° to 93.4°).

RESULTSA total of 167 pedicle screws were inserted intraoperatively, with 138 screws (82.6%) in grade I, 26 screws (15.0%) in grade II, 4 screws in grade III (2.4%), but no screws in grade IV according to the CT image. There were 29 (17.4%) screws perforated, and 163 (97.6%) screws could be accepted. In the control group, a total of 165 pedicle screws were inserted intraoperatively, with 98 screws (59.4%) in grade I, 39 screws (23.6%) in grade II, 21 screws in grade III (12.7%), and 7 screws in grade IV (4.2%). There were 67 (40.6%) screws perforated, and 137 (83.0%) screws could be accepted. The grade distribution of screw position, ratio of perforated and accepted screws were significantly different between the two groups respectively (Z=-5.013, P=0.000; χ2=9.347, P=0.002; χ2=20.242, P=0.000). The correction rate of Cobb angle were (74.1±10.0)% vs (69.7±17.6)%; blood loss were (455±447) ml vs (415±389) ml; operation duration were (163.5±53.7) min vs (164.0±48.7) min; and the changes of creatinine level pre- and post-operatively were (-5.3±3.2) μmol/L vs (-3.4±3.1) μmol/L; all above data had no significant differences respectively (t=0.696, P=0.496; t=0.214, P=0.833; t=0.022, P=0.983; t=1.375, P=0.192). There were no complications related to pedicle screw insertion in each group.

CONCLUSIONThe novel patient-specific drill guide template can be used to assist the insertion of pedicle screws in scoliosis cases with much higher accuracy than that of freehand method and fair safety.
