By now,the mutations of C-KIT gene and PDGFRA have been regarded as the most important primary incidences.The latest results have revealed the fact that the abnormal expressions of p53,p16,p21 WAF-1,p27 and E-cadherin(cDH1) which were labeled as anti-oncogenes in most of human tumors,existed in the progression of gastrointestinal stromal tumor.Therefore,we put forward the theory that gene mutaion may lead to the instability of DNA that further promotes mutation of short tandem repeat in anti-oncogene coding region,on basis of which,that finally lead to the malignant progession of gastrointestinal stromal tumor by anti-oncogene mutation.

Objective To evaluate the effect of tetramethyl pyrazine(TMP)on noise induced hearing loss (NIHL) in hypobaric environment. Methods Normal guinea pigs were randomly divided into two groups, in which the animals were exposed to noise for 1 day or 7 days, respectively. Each group was randomly divided into 3 subgroups: control, TMP-treatment and TMP-pretreatment groups. All animals were exposed to 110dB white noise in hypobaric chamber to repreduce a low pressure environment of 5500m altitude. The mechanism underlying TMP protection was studied by detecting the auditory brainstem response (ABR). Results ABR threshold shift in different degrees occurred in every group, especially in animals exposed to 4kHz. The threshold shifts increased in extent along with prolongation of exposure time. The longer they were exposed, the more ABR threshold shifts. ABR threshold shifts occurred more severely in control group compared with the two TMP-utilized groups. Conclusion TMP has certain protective effect on NIHL in a hypobaric environment.

OBJECTIVETo explore the correlation between signs of living body in abdominal and pelvic cavities and syndrome typing of Chinese medicine (CM) in colorectal cancer patients.

METHODSTotally 112 colorectal cancer patients undergoing open abdominal surgery or laporoscopic surgery were syndrome typed as five types, i.e., inner-accumulation of damp and heat, blockage of stasis and toxin, Pi-Shen yang deficiency, blood-qi deficiency, Gan-Shen yin deficiency. Signs of living body in abdominal and pelvic cavities were collected. The correlation between signs of living body in abdominal and pelvic cavities and syndrome typing of CM were analyzed.

RESULTSRed colorectal canals or mass were dominated in colorectal cancer patients with inner-accumulation of damp and heat syndrome. Dark purple colorectal canals or mass were dominated in colorectal cancer patients with blockage of stasis and toxin syndrome. Reddish colorectal canals or mass were dominated in colorectal cancer patients with blood-qi deficiency syndrome. Pale colorectal canals or mass were dominated in colorectal cancer patients with Pi-Shen yang deficiency syndrome. Whitish or red-white stripes were dominated in colorectal cancer patients with Gan-Shen yin deficiency syndrome. Dropsy colorectal canal was associated with Pi-Shen yang deficiency syndrome. Intracavitary effusion was often seen in colorectal cancer patients with inner-accumulation of damp and heat syndrome. The effusion was yellowish in less amount. Intracavitary adhesion was often seen in colorectal cancer patients with blockage of stasis and toxin syndrome. There was no correlation between the maximum diameter of mass or each syndrome type of CM.

CONCLUSIONThere existed correlation between signs of living body in abdominal and pelvic cavities and syndrome typing of CM, which could be taken as one of references for syndrome typing of colorectal cancer patients.

ObjectiveTo observe the effect of acupuncture at the ghost points on anxiety and depression in methamphetamine (MA)-dependent subjects.MethodSixty MA-dependent males were randomized into a control group, acupuncture groupⅠand acupuncture groupⅡ. The control group didn’t receive any intervention; inacupuncture groupⅠ, bilateral Neiguan (PC6), Shenmen (HT7), Sanyinjiao (SP6), and Jiaji points (EX-B2) were selected; Shuigou (GV26), Shangxing (GV23), Chengjiang (CV24), and bilateral Daling (PC7), Jianshi (PC5), Shenmai (BL62), and Quchi (LI11) were selected in acupuncture groupⅡ. For the three groups, treatment was given three times a week, totally for 12 times. The Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale (HAMD) were observed before treatment, and respectively after 1, 2, 3, and 4-week treatment.ResultAfter the first-week treatment, the HAMA and HAMD scores in acupuncture groupⅡwere significantly lower than that in the control group (P<0.05);afterthe second, third, and fourth week, the HAMA and HAMD scores in acupuncture groupⅠandⅡwere significantly lower than that in the control group (P<0.05); after the second and third week, the HAMD score in acupuncture groupⅡwas significantly lower thanthat in acupuncture groupⅠ(P<0.05). However, after 4-week treatment, there was no significant difference in comparing the HAMD score between the two acupuncture groups (P>0.05).ConclusionAcupuncture at the ghost points and at the effective points selected according to previous studies both can improve anxiety and depression state in MA-dependent subjects, but acupuncture at the ghost points can possibly produce a more significant effect in improving depression state in MA-dependent subjects in the midway of the treatment.

Cellular schwannoma is a rare benign tumor of the peripheral nerves.The tumor is consist of spindle cells which arranged in interwoven bundles,and lacking the mesh district and palisading structure.The tumor cells are abundant,with coarse chromatin,deeply stained nuclei and in multiforms.So the tumor may easily be misdiagnosed as various types of spindle cell sarcoma.Intraperitoneal cellular schwannoma may also be mistaken as gastrointestinal stromal tumors.In this article,the clinical characteristics,diagnosis and treatment of cellular schwannoma were analyzed based on the clinical data of a patient with cellular schwannoma in the gastric wall misdiagnosed as gastric stromal tumor.

Objective:To investigate the efficacy of three different methods of digestive tract reconstruction after total gastrectomy.Methods:A total of 106 cases underwent the uncutted Roux-en-Y esophagojejunostomy with a jejunal pouch(group A,n=38) ,Roux-en-Y esophagojejunostomy with the J-type jejunal pouch(group B,n=31) ,and Roux-en-Y esophagojejunostomy with the Orr-type jejunal pouch(group C,n=37) respectively.The clinical data were retrospectively studied.The digestive tract reconstruction time,the post-operative complication incidence rate,postprandial symptoms,food-intake quantity,weight,serum nutritional parameters and emptying time of the gastricsubstitute were compared respectively.Results:The reconstruction time was the shortest in group A,which was significantly shorter than that in group B(P0.05) ,Group A was significantly lower than group B and C in the incidence of roux stasis syndrome.The Visick score of group A were superior to those of group B and C in 6 and 12 months after operation.The food intake gain of group A and B were superior to that of group C 6 and 12 months after operation.There were no significant differences among 3 groups in the term of weight,Hb and ALB loss and prognosis nutritional index(PNI) 6 months postoperatively.Weight and ALB loss in group A and B were lower than those in group C 12 months postoperatively,but PNI was higher in group A and B than those in group C.Emptying time of the gastric substitute was prolonged both in group A and B 12 months postoperatively.Conclusion:The uncutted Roux-en-Y esophagojejunostomy may act as an adoptable method of digestive tract reconstruction after total gastrectomy for gastric cancer.

BackgroundResearches demonstrated that the levels of soluble CD44 (sCD44)molecule in aqueous is significantly higher in primary open-angle glaucomous(POAG) eye than normal eye,but how the sCD44 would affect the expression of apoptosis protein in trabecular meshwork cells is below understanding.Objective The present study was to investigate the effect of sCD44 on the expression of regulatory proteins bcl-2 associated death factor bad in trabecular meshwork cells in the patients with POAG.MethodsHuman scleral tissue with trabecular meshwork were obtained from POAG patients during the surgery.The trabecular meshwork cells were primarily cultured by explant culture method and identified by immunochemistry.The third generation of cells were incubated with free-serum DMEM/F12 medium added differnt dosages of sCD44 (0,1,5,10,25,50 mg/L) for 48 hours.The expression of bad protein in cultured cells was detected using cell counting kit-8 (CCK-8) as the absorbance values at 490 nm(A,90 value),and the bad protein level in cultured cells was assayed by ELISA.ResultsThe cultured cells showed the positive response for laminin ( LM ),neuron specific enolase ( NSE ),fibronectin ( FN ) monoclonal antibodies.The CCK-8 assay showed that the A490 values of the trabecular meshwork cells in 0,1,5,10,25,50 μg/L of sCD44 groups were 0.2460±0.0019,0.1874±0.0015,0.1570±0.0016,0.1302±0.0019,0.1084±0.0018,0.0940±0.0020 respectively with a statistically significant difference among the 6 groups( F =14.922,P =0.000 ),and the A490 values in various dosages of sCD44 groups were significantly lower than the 0 μg/L sCD44 group (P=0.013,0.008,0.011,0.005,0.004).The ELISA assay showed that bad protein levels in 0,1,5,10,25,50 μg/L of sCD44 groups were ( 114.8461 ± 2.9560 ),( 137.8270 ± 2.4259 ),( 161.4194 ± 3.7381 ),( 170.9453 ± 3.2006 ),( 221.2252 ±4.3738 ),( 324.6167±4.4220) ng/L,showing a total difference among them ( F =16.610,P =0.000 ),and the bad protein levels in various dosages of sCD44 groups were significantly lower than the 0 μg/L sCD44 group( P =0.017,0.013,0.008,0.007,0.006).ConclusionssCD44 can contribute to the apoptosis of the trabecular meshwork cells in patients with POAG in certain dose range by regulating the apoptosis regulatory proteins bcl-2 associated death factor bad.

?AIM:To investigate the measurement of central anterior chamber depth ( ACD ) in patients with acute primary angle - closure glaucoma ( APACG ) with A - scan ultrasound, Pentacam and ultrasonic biological microscope ( UBM) .?METHODS: Thirty-five patients (35 eyes) with APACG were selected, of whom central ACD were measured with A-scan ultrasound, Pentacam and UBM.?RESULTS: The measurement values of ACD with A-scan ultrasound, UBM and Pentacam were 1. 5633±0. 2089, 1. 5783 ± 0. 2067, 1. 6275 ± 0. 2296mm, which was equal variance tested by the homogeneity of variance, and was significant different by multiple comparision (F=4. 074, P=0. 026). The difference of ACD between the two groups of A-scan ultrasound and UBM, A-scan ultrasound and Pentacam, UBM and Pentacam were statistically significant ( P = 0. 032, 0. 023, 0. 012 ). Altman- Bland analysis showed that the three methods were not consistent with each other.?CONCLUSION: The ACD value of the APACG with the three methods is the largest using Pentacam, followed by UBM and A - scan ultrasound. In clinical the three methods with different advantages can complement each other, but cannot be replaced. In order to obtain more accurate results, we should combine the advantage and make comprehensive analysis.

Abstract? AIM: To analysis the relation of severity of rhegmatogenous retinal detachment with the levels of amino acids and vascular endothelial growth factor ( VEGF) in the serum and in subretinal fluid.? METHODS: Forty -eight patients ( 52 eyes ) with rhegmatogenous retinal detachment treated in our hospital were selected.According to the degree of retinal detachment, patients were divided into <1/2 quadrant group, 1/2-3/4 quadrant group and>3/4 quadrant group. Fifty-five healthy objects for physical examination in our hospital were selected as the control group, to compare the differences of amino acids and VEGF levels in the serum.Correlation analysis on VEGF levels and amino acids in the serum and in subretinal fluid among patients with different grades of rhegmatogenous retinal detachment was conducted.? RESULTS: In patients with rhegmatogenous retinal detachment, the tryptophan in serum was 28.59±4.46mg/L, phenylalanine 8.95 ±2.55mg/L, methionine 8.15 ±2.17mg/L, valine 28.62 ±5.29mg/L, histidine 18.96 ±1.85mg/L and VEGF 589.92 ±185.34μg/L, which were higher than those in the control group, and the difference was statistically significant(P<0.05).The levels of phenylalanine was 9.85 ±1.21mg/L, histidine 20.63 ±2.07mg/L and VEGF 718.69 ± 283.34μg/L in the subretinal fluid of>3/4 quadrant group, which were significantly higher than those in the <1/2 quadrant group and 1/2-3/4 quadrant group ( P<0.05). VEGF in the subretinal fluid of VEGF in the rhegmatogenous retinal detachment group were positively correlated with phenylalanine (r=0.542, P<0.001), and histidine (r=0.782, P<0.001).?CONCLUSION: The levels of amino acids and VEGF in the subretinal fluid of patients with rhegmatogenous retinal detachment was higher than those in normals and increased with the severity of retinal detachment.
