Objective Hepatocyte growth factor (HGF) has been proposed to be used as an endogenous cardioprotective agent. The aim of the present study was to investigate the anti-apoptosis effect of HGF on rat cardiomyocytes after being irradiated by single dose gamma ray. Methods The study was performed using primary cell cultures of cardiomyocytes isolated from hearts of new-born rats. After being cultured for 72h in vitro, cardiomyocytes were irradiated with gamma ray in a single dose of 20Gy. In the HGF treated groups, cells were incubated with HGF in the dose of 20 and 40ng/ml 3h prior to irradiation, respectively. At 48h post-irradiation, the concentration of LDH in the supernatant of cell culture was determined. Apoptosis and cell cycle were determined with flow cytometry. Results LDH concentration in the supernatant of cell culture of irradiated cardiomyocytes was increased significantly compared to that of un-irradiated cells (P

Objective The clinical manifestations of Parkinson''s disease (PD) are divided into non-motor symptoms and motor symptoms.Constipation is one of the common symptoms of non-motor symptoms of the disease.Constipation symptoms in PD generally occur earlier for 5~20 years, while drug treatment for PD constipation can lead to gastrointestinal damage.This study investigated the improvement in the treatment of anorectal dynamics and constipation symptoms in Parkinson''s disease by oral mosapride and press-needle therapy of Shu-Mu point.Methods 60 patients diagnosed as constipation of Parkinson''s disease were randomly divided into control group and treatment group, 30 cases in each group;patients in the control group were treated with oral mosapride tablets, while patients in the treatment group received press-needle therapy, three times per week.The observation course in both groups last for three months and follow-up visits were conducted before and after the course.Efficacy evaluation, PAC-QOL scale and anorectal dynamic examination were applied in the follow-up visit.Results The efficiency of treatment group was 81.7%, significantly higher than control group (70%), representing significant difference between the two groups (P<0.05).Both the methods could improve the PAC-QOL scale, and significant difference was found in comparison to that before the treatment(P<0.01), while no statistical significance was found between treatment group and control group after treatment(P>0.05).As to the anorectal dynamics, significant difference was found before and after the treatment in both groups (P<0.05, P<0.01), while no statistical significance were found between the two groups after treatment(P>0.05).Conclusion Both oral mosapride and press-needle can improve the quality of life and anorectal dynamics for PD patients, representing no significant difference.However, compared with mosapride, the overall efficacy of press-needle is better in improving the symptoms of constipation in PD, featuring more convenience, higher safety, less pain and no side effect, and it is worthy of clinical application.

Objective To investigate the clinical curative effect of Qingrehuatan method in the treatment of insomnia elderly patients with benzodiazepines dependence.Methods From April 2016 to April 2017,49 insomnia elderly patients with benzodiazepines dependence in the Second People's Hospital of Zhoushan were divided into the observation group(20 cases)and control group (29 cases)according to the different treatment methods.In the gradual reduction at the same time,the control group was treated with trazodone,the observation group was treated with Qingrehuatan method.Before treatment and after treatment for 1course,the revised Pittsburgh sleep quality scale (PSQI),index of insomnia symptom score,TCM symptom score,Zung Anxiety Rating Scale score,Wechsler Adult Intelligence Scale(WAIS－RC)and Wechsler Memory Scale(WMS－RC)score were observed in the two groups. Results After treatment,the rate of withdrawal and discontinuation of the observation group was significantly higher than that of the control group (90.0% vs.68.9%),the difference was statistically significant (χ2＝6.918,P＜0.05).After treatment,the PSQI scores and symptom scores of the two groups were significantly decreased,and the PSQI scores and TCM symptom scores of the observation group improved significantly better than those of the control group[(8.8 ±1.1)points vs.(10.6 ±1.3)points,(2.9 ±0.8)points vs.(4.6 ±1.2)points],the differences were statistically significant(t＝5.063,5.535,all P＜0.05).After treatment,the Zung Anxiety Scale scores of the two groups were significantly lower,and the improvement of the observation group was significantly better than that of the control group[(42.90 ±5.65)points vs.(48.21±5.27)points],the difference was statistically significant(t ＝ 3.366,P＜0.05 ).After treatment,the long －term memory,short －term memory and memory quotient of the two groups were significantly increased,and short－term memory and memory quotient of the observation group improved significantly better than those of the control group[(23.30 ±5.31)points vs.(20.55 ±6.58)points,(76.67 ± 12.70)points vs.(67.36 ±19.13)points],the differences were statistically significant (t＝2.274,2.047,all P＜0.05 ).Conclusion Qingrehuatan method in the treatment of insomnia elderly patients with benzodiazepines depend-ence can improve the possible reduction in the process of stopping drug withdrawal symptoms and memory function, and can improve the symptoms of patients at the same time,and it is worthy of clinical application.

OBJECTIVETo explore the expression of Bcl-2 mRNA and its effect on prognosis of patients with primary gastrointestinal diffuse large B-cell lymphoma (PGI-DLBCL).

METHODSReal time quantitative PCR was used to determine the expression of Bcl-2 mRNA in 40 PGI-DLBCL patients and 17 healthy controls. The association of Bcl-2 expression with clinicopathological features and prognosis of the patients was analyzed.

RESULTSThe expression level of Bcl-2 mRNA in PGI-DLBCL patients was 1.03 ± 0.93, significantly higher than that of the controls (0.41 ± 0.21) (P < 0.05). The expression of Bcl-2 mRNA in stage IIE-IV patients (1.28 ± 1.01) was significantly higher than that in the stage I-II2 patients (0.62 ± 0.61) (P < 0.05). The expression of Bcl-2 mRNA in patients with international prognostic index (IPI) score >2 (1.95 ± 1.27) was significantly higher than those with IPI score &le; 2 (0.86 ± 0.75)(P < 0.05). The expression of Bcl-2 mRNA in patients with complete remission (CR) (0.71 ± 0.58) was significantly lower vs. 2.42 ± 0.91 in patients with no CR (P < 0.05). Univariate analysis indicated that β2-MG, IPI score>2, the Lugano staging, and Bcl-2 mRNA expression were associated with overall survival (OS) and progression-free survival (PFS) (P < 0.05). Multivariate analysis indicated that IPI score>2 was independently associated with OS (P < 0.05), and both IPI score >2 and Bcl-2 mRNA expression were independently associated with PFS (P < 0.05).

CONCLUSIONSThe expression of Bcl-2 mRNA in the tumor tissue of PGI-DLBCL patients is significantly higher than that in controls. PGI-DLBCL patients with higher expression of Bcl-2 have a poor chemotherapy response and inferior prognosis. IPI score >2 and higher expression of Bcl-2 mRNA are independent poor prognostic factors for PFS in PGI-DLBCL patients.

Objective:To construct a three-dimensional imaging model of the pancreatic head based on the embryological fusion plane, and to provide morphological parameters of the pancreatic head for future developments of basic and clinical researches on the pancreas.Methods:Histologic cross-sections of the pancreatic head with its adjacent structures were made from healthy cadavers. Immunohistochemical analysis of pancreatic polypeptide antibody was then performed to verify the existence and location of the embryological fusion plane reported previously. The histologically positioning method of the embryological fusion plane was then applied to the corresponding sections on computed tomography (CT). Based on the results of the above work, volunteers from the Affiliated Changzhou No. 2 People's Hospital of Nanjing Medical University were then used as research objects. A three-dimensional visualization reconstruction software was used to perform CT image-based structures to include the abdominal pancreas, dorsal pancreas head, and embryo fusion surface. Three-dimensional reconstruction of the pancreatic head, and morphological measurements of the relevant structures of the pancreatic head were then made.Results:Immunohistochemical analysis verified the existence and the position of the embryological fusion plane. The histologically positioning method was then successfully applied to the CT sections. The three-dimensional imaging model of the pancreatic head containing the embryological fusion plane, dorsal segment and ventral segment of head were built based on CT images. A total of 35 volunteers were included, including 19 males and 16 females, aged (48.26±8.26) years, and with a BMI of (22.29±1.78) kg/m 2. The morphological results showed that the volume of the pancreatic head, dorsal pancreas and abdominal pancreas were (32.80±8.15) cm 3, (22.21±6.94) cm 3, (10.59±3.87) cm 3, and the area of the embryo fusion surface was (12.46±3.20) cm 2. All volunteers were then grouped according to gender. Statistical analysis showed that there were no significant differences in the total pancreatic head volume, dorsal pancreatic head volume, abdominal pancreatic volume, and embryo fusion area among the groups ( P>0.05). Conclusions:It was feasible and practical to build a three-dimensional imaging model of the pancreatic head based on the embryological fusion plane by using a 3D computer system. This model and its morphological parameters could provide a new tool for research on pancreas.
