Chinese Journal of Primary Medicine and Pharmacy 2015;(23):3591-3593
Objective To observe the changes of serum gastrin (GAS)and plasma motilin (MTL)in patients with primary bile reflux gastritis.Methods 80 patients with primary bile reflux gastritis were selected.The serum GAS and plasma level of MTL were observed,and the results were compared with 80 healthy people.Results The content of MTL in plasma of the study group (282.37 ±31.56)pg/mL was significantly lower than that in the control group (t =-21.352,P <0.01).The level of serum GAS (91.28 ±27.71)pg/mL was significantly higher than the control group (t =-28.388,P <0.01).Conclusion Compared with the healthy people,secretion of MTL in patients with primary bile reflux gastritis has insufficient phenomenon,and has the excessive secretion of GAS in the body,this may be a factor in the pathogenesis of the disease.
2.B-ultrasound guided interventional radio frequency for climacteric dysfunctional uterine bleeding
Chinese Journal of Minimally Invasive Surgery 2001;0(06):-
Objective To investigate the curative effects of B-ultrasound guided radio frequency therapy in the treatment climacteric dysfunctional uterine bleeding. Methods B-ultrasound guided radio frequency therapy was adopted in 121 cases of dysfunctional uterine bleeding with an exclusion of malignant lesions. Results The operation time was 6 min~12 min, with a mean of 8.5 min. No adverse effects were observed. The cure rate and marked effective rate were 88.4% (107/121) and 11.6% (14/121) in the 3rd postoperative month; the cure rate, marked effective rate and effective rate were 78.3% (36/46), 19.6% (9/46) and 2 1% (1/46) in the 24th postoperative month, respectively. Conclusions B-ultrasound guided radio frequency therapy in the treatment of climacteric dysfunctional uterine bleeding is simple and minimally invasive, being highly recommended.
3.The Effect of Trichostatin A on Histone Acetylation and mRNA Expression of ING1b Gene in Human Colon Cancer Cell Line Colo205
Chinese Journal of Clinical Oncology 2010;37(4):181-183
Objective: To investigate the effect of Trichostatin A (TSA) on histone acetylation and expression of ING1b mRNA in Colo205 human colon cancer cell line. Methods: Human colon cancer Colo205 cells were cultured and divided into 4 groups. Cells in the control group (group A) was treated without TSA. In the other three groups, cells were treated with 3 different concentrations of TSA: 50μg/L (group B), 100μg/L (group C), and 200μg/L (group D). At 24 hours after treatment, the level of histone H3 acetylation was analyzed by chromatin immunoprecipitation (CHIP) and the expression of ING1b mRNA was detected by RT-PCR with qPCR. The growth of Colo205 human colon cancer cells in group C and D was obviously inhibited compared with that in group A and B. Results: The Ct value of histone H3 acetylation and mRNA expression of ING1b in group A were 23.25± 0.08 and 23.32±0.05, respectively. After treatment with TSA, the 2~(-△△Ct) value of histone H3 acetylation in group B, C, and D were 1.12, 4.21 and 4.38, respectively. The level of histone H3 acetylation in group C and D was increased more compared with that in group A (P<0.05) and there was no difference between group B and group A (P>0.05). The 2~(-△△Ct) value of the expression of ING1b mRNA in group B, C and D were 1.33, 4.52 and 4.62, respectively. The expression of ING1b mRNA in group C and D were more than that in group A (P<0.05). Group B and group A had a similar level of ING1b mRNA expression (P>0.05). Conclusion: The histone acetylation is probably responsible for ING1b expression silencing in Colo205 human colon cell line. TSA at 100μg/L can increase the level of acetylation and activate the gene transcription which is silenced by low level of acetylation and induce the expression of gene, inhibiting the growth of tumor cells.

objective To investigate the diagnosis and treatment of hepatic focal nodular hyperplasia(FNH).Methods Twelve cases with hepatic focal nodular hyperplasia from January 2003 to December 2006 in our hospital were reviewed retrospectively. Results Three cases had epigastric discomfort(25%),5 cases with elevated ALT(41.67%),3 cases with elevated AST(25%),2 cases with elevated AFP(16.67%),one patient was of positive HBsAg(8.33%).The rate of preoperative correct diagnosis made by ultrasound,CT and MRI was 0,20%and 25%respectively,there was no significant difference between CT and MRI.Final diagnosis was established by stlrgical resection and pathology in 11 cases and by needle biopsy in one case.All cases recovered and were followed-up with an average of 28 months.No recurrence was found in cases undergoing surgical resection. Conclusion The rate of correct preoperative diagnosis for FNH is low,definite diagnosis depends on pathologic examination.The prognosis is good,however,most patients in this series underwent resection because of possible malignancy especially in eases of cirrhotics.

Purpose:To investigate the clinicopathological characristics of colorectal mucinous adenocarcinoma (MUC),which is generally bel ieved to have a poor prognosis,in an attempt to assess ways in which the surgica l outcome can be improved. Methods:From 1994 to 2003,1 715 large intestinal cancer patient s underwent operation, among them, 197 patients were with MUC. The clinicopathol ogical parameters and prognosis of MUC and non-MUC were analyzed retrospectivel y. Results:There were no significant differences in sex , tumor si te and size. Patients with MUC had higher rate of serosal invasion (MUC:59.9% vs non-MUC: 35.1%) , invasive type lymph-node involvement (MUC:41.6% vs non-MUC 21.6%). Patients with MUC were of more advanced stage(D stage:MUC :44.1% vs non-MUC: 22.1%). Conclusions:Based on these findings , a more aggressive attitud e toward surgical intervention is recommended , including extensive lymph node d issection and the resection of adjacent organs that seems to be affected microsc opically , to improve the surgical outcome of this clinical entity.

Objective: To study the injury characteristics of blast injury in maxillofacial region wounded by spherical explosive. Methods: Spherical explosive was used to wound maxillofacial region in rabbits , after gross observation of the trauma , bone tissue specimens were collected from 0.5 or 1.0 cm to the boundary of wound 6 hours, 3 and 7 days after wounding respectively, the samples were prepared and stained with HE and modified Mallory's trichrome staining and observed under light microscope . Microcirculation in wounded bone was studied by ink injection and observed in ground bone sections. Results: No changes were found 6 hours after injury. Inflammatory infiltration were found 3 days after injury.Osteonecrosis was observed 7 days after injury, the structure of bone beyond 0.1 cm of the wound was found to be normal and restoration of bone was observed. Conclusion : Pathological changes of mandible injured by spherical explosive are similar to those of usual fracture except that the wound of blast injury is seriously polluted.

Objective To investigate the effects of Buyanghuanwu decoction on infiltration of neutrophils and expression of ICAM-1 after middle cerebral artery occlusion (MCAO) in rats. Methods Rats were pretreated with Buyanghuanwu decoction(13 g/kg and 26 g/kg) for 7d and then subjected to cerebral ischemia/reperfusion injury induced by an MCAO. After a 90min ischemia and a 24h reperfusion, the neurological deficit and the survival neurons were determined. The effects of Buyanghuanwu decoction on infiltration of neutrophils and expression of ICAM-1 by immunohistochemistry are evaluated. Results Buyanghuanwu decoction significantly ameliorated the neurological deficit and increased survival neurons . The myeloperoxidase (MPO) positive cells and the ICAM-1 positive vessels in the vehicle-treated rats were increased significantly (P

OBJECTIVE To analyze 1000 Hz probe tone tympanometry of middle ear with different volume of fluid, and to evaluate the role of 1000 Hz probe tone tympanometry in the diagnosis of presence of fluid in tympanic cavity. METHODS Tympanometries with 1000 Hz or 226 Hz probe tone were obtained from all the guinea pigs with different volume of fluid in tympanic cavity using GSI33 analyzer and tympanometry curves were analyzed. RESULTS There was a significant difference of the peak pressure of 1000 Hz tympanometry among all test groups and control group. The peak pressure decreased with the increasing of fluid volume in tympanic cavity. CONCLUSION Tympanometry with 1000 Hz probe tone can be used in the diagnosis of fluid in tympanic cavity, and it can be an indicator of volume of fluid in tympanic cavity.
