Atrophic gastritis and gastric ulcer in rat models were induced with liquid ammonium and acetic acid respec- tively. Observation was made on the protective action of Weitongling on gastric mucosa. Quantitative observation was made on the regenerated mucosa of healing gastric ulcer by mucous histochemical staining, Ag-NoR staining, immuno - histo - chemical staining, and Forii Akira method in models induced by rubbing of glacial acetic acid. Comparison was also made between the above models after treated with Weitongling and that of natural healing mucosa. Further observations were made by density counting of acute and chronic inflammatory cells in atrophic gastrilis in rats, length of glands in the fundus, as well as thickness of PAS ( + ) layer in mucosa of gastric fundus. Results showed that Weitongling yields satisfactory results of protecting the gastric mucosa.

Objective To investigate the expression of NF-κBp65 in hippocampus after the XST intervention therapy in the SD rats with global cerebral I/R injury and testify the protective effect of XST after global cerebral I/R injury.Methods 72 healthy SD rats were randomly divided into 3 groups,sham operation(SO) group ( n =24),I/R group( n =24) and XST group( n =24).The model of acute global cerebral ischemia/reperfusion (including:I/R and XST group) injury was produced by means of simple Pulsinelli- brierley's four arteries occlusion method.H.E.staining was performed to detect the number of surviving neurons and TUNEL was used to detect the rate of neurons apoptosis.The expression activation of NF-κB p65 in hippocampus comu-ammonis ( CA1 ) region were examined by immunohistochemical method (SABC).Results The survival pyramidal neurons in the XST group continued to increase,and it was significantly more than the I/R group at each time-point after reperfusion[ (99.23 ±4.22)/mm vs (75.83 ±7.17 )/mm,(80.93 ± 5.36)/mm vs (51.50 ± 8.26 )/mm,(103.24 ± 5.48 )/mm vs (35.67 ± 13.17 )/mm,( 126.22 ± 7.54 )/mm vs (9.83 ± 4.71 )/mm ],the differences were statistically significant ( P ＜0.01 ).The apoptosis rate of pyramidal cell in the XST group at each time-point were more significantly reduced than the I/R group [ ( 8.82 ± 2.71 ) ％ vs ( 22.58 ± 4.68 ) ％.( 19.15 ± 6.23 ) ％ vs (42.68 ± 3.04 ) ％,( 11.82 ± 2.87 ) ％ vs ( 55.51 ± 6.81 ) ％,( 8.44 ± 3.23 ) ％ vs ( 71.69 ± 7.71 ) ％ ],the differences were statistically significant ( P ＜0.01 ).The positive neurons of NF-κBp65 expression in the XST group at different time-points were significantly less than the L/R group[ ( 13.20 ±2.50) vs ( 18.00 ± 1.87),(8.20 ±5.31) vs (41.60±3.65),(6.70±3.36) vs (55.30±5.10),(7.10±3.57) vs (72.80 ±4.71)],the differences were statistically significant ( P ＜ 0.05,P ＜ 0.01 ).Conclusions After global cerebral ischemia/reperfusion,XST could protect the brain from global cerebral ischemia/reperfusion injury by holding up the expression of NF- kappaB p65,and inhibiting neuronal apoptosis,and increasing the number of surviving neurons.Thus,the results of this experiment could provide a powerful and weighty objective indication for XST being used during cerebral resuscitation.

Objective To investigate the relationship between alexithymia and event-related potential P300 in patients with somatoform disorders.Methods Forty-two patients aged 18 to 65 years fulfilling ICD-10 diagnosis criteria for somatoform disorders were recruited as experiment group.Forty normal healthy persons were selected as control group.The Toronto alexthymia scale-20 (TAS-20) was employed to investigate the alexithymia of the subjects.P300 potentials was employed to investigate the cognitive ability of the subjects.A comparison was made between the patients and the healthy subjects.Results The latencies of N1,P2,N2 and P3 were significantly longer in patients with somatoform disorder than those in the normal controls (P ＜ 0.05 or 0.01),the amplitudes of N2 and P3 were significantly lower in the patients (P ＜ 0.05 or 0.01).The three factors scores and the total score of TAS-20 test in patients with somatoform disorder were significantly lower than those in the normal controls (P ＜ 0.05 or 0.01).There was significant correlation between the latency and the three factors scores and the total score of TAS-20 as well as between the amplitude of P300 and the three factors scores and the total score of TAS-20:the latencies of N1,P2,N2 and P3 recorded at Pz was positively correlated with the factors scores (r =0.32 ～ 0.48,P ＜ 0.05 or 0.01),and the amplitudes of N1,P2,N2 and P3 recorded at Pz was negatively correlated with theTAS-20 scores (r=-0.31 ～-0.51,P＜0.05 or0.01).Conclusions There existed significant correlation between the alexithymia and cognitive impairment in patients with somatoform disorders.Both alexithymia and event-related potential P300 can be used as a clinical evaluation index for patients with somatoform disorder.

Objective To evaluate the effect of transverse position and numbers on the stability of the spinal pedicle screw fixation during the pedicle cortex perforation. Methods The vertebral compression fracture was performed in the L1 vertebral body using the Chiba's method from 60 fresh thoracic and lumbar vertebrae samples of sheep(T13-L3),which were randomly divided into 6 groups(A,B,C,D,E,and F)using a lottery method. Bilateral pedicles of vertebral arch of T14 and L2 were inserted pedicle screws,connecting titanium rods to fix T14-L2 segments. Then the samples of groups B,C,D,E,and F were removed a quarter of right side of lateral T14 thoracic pedicle cortical,which were considered the pedicle cortex perforation model. Finally,each group was fixed on different numbers of crosslinks:group A(0 crosslink,Intact),group B(0 crosslink,NCL),group C(1 crosslink,1/2 of the rods,MCL),group D(1 crosslink,1/3 of the rods close to T14,PCL),group E(1 crosslink,2/3 of the rods away from T14,DCL)and group F(2 crosslinks,1/3 and 2/3 of the rods respectively,TCL). After all samples were subject to 10 000 times of fatigue test with biomechanics test machines,the axial compressive stiffness,range of the motion(ROM)of the 6 directions(flexion,extension,lateral bending,and axial rotation),and the maximum pullout of the screws of the T14 pedicle cortex perforation were measured and compared among these 6 groups. Results The axial compressive stiffness in groups A,C,D,E,and F was significantly higher than that in group B(all P<0.05),and group A was significantly higher than group F(P<0.05) . The maximum pullout in groups A,C,D,E,and F were significantly higher than that in group B(all P<0.05),and group A was significantly higher than group F and groups C,D,and E were significantly lower than group F(all P<0.05). ROM of flexion,extension,lateral bending,and axial rotation in groups A,B,C,D,E,and F were significantly lower than that in group B(P=0.000),and ROM of left and right axial rotation in groups C,D,and E were significantly higher than in that group F(P=0.000). Conclusions During the pedicle cortex perforation,adding of one crosslink can improve the stability of the pedicle cortex perforation,and adding of two crosslinks can approximately achieve the same stability as the pedicle screw fixation with no pedicle cortex perforation. The location of the crosslink has no obvious effect on the short segment of spinal fixation.

The effect of nateglinide or sequential treatment with metformin on glycemic stability in newly diagnosed type 2 diabetes was investigated. Thirty-four cases of newly diagnosed type 2 diabetes received nateglinide therapy, or sequential treatment with metformin according to fasting and postprandial blood glucose, and were classified into isolated nateglinide therapy group(n=14) and sequentially treated with metformin group(n=20). Glycemic stability, reflected by mean amplitude of glycemic excursions(MAGE) and HbA1C, was determined in all patients before and after therapy for three months. HbA1C and MAGE in two groups were all improved after treatment(P＜0.05). The therapy of nateglinide alone or combined with metformin can significantly improve glycemic stability in newly diagnosed type 2 diabetes.
