Two patients underwent liver transplantation of blood type incompatibility were collected from Fuzhou General Hospital of Nanjing Military Area Command of Chinese PLA. Case 1: A male who had primary hepatic carcinoma underwent classic orthotopic liver transplantation; the blood of donor was type A, and the blood of recipient was type O. Case 2: A female having history of type B hepatitis underwent classic orthotopic liver transplantation due to pregnancy combining with severe liver disease and coagulation disorder; the blood of donor was type B, and the blood of recipient was type O. Immunohistochemistry staining was used to observe pathological changes and deposition of various immunoglobulin and complement in two cases following liver transplantation of blood type incompatibility under optic microscope and to investigate diagnostic standard of humoral rejection. The results showed that linear or granular depositions of IgG, IgM, IgA, C4c, C4d, and Clq were found in endothelial cells of hepatic sinusoid, suggesting that IgG and other immunoglobulin exhibited a strongly positively diffused deposition on the endothelial cells of hepatic sinusoid, while expression of C4d and other complements was also found. All those mentioned above could be considered as evidences to prove onset of humoral rejection in transplanted liver tissue.

Imatinib mesylate has been commonly used in the treatment of patients with chronic myeloid leukemia (CML). However, a significant number of CML patients treated with imatinib developed thrombocytopenia. Platelet-derived growth factor (PDGF)/platelet-derived growth factor receptor (PDGFR) plays a significant role in the regulation of thrombopoiesis. It is suggested that imatinib may block the PDGF/PDGFR and PI3-K/Akt pathway, then inducing the apoptosis of megakaryocytes and developing thrombocytopenia in these patients. In this review, the potential molecular mechanism of imatinib-induced thrombocytopenia in the treatment of CML patients is discussed, including imatinib and thrombocytopenia, PDGF/PDGFR and thrombopoiesis, potential mechanism of imatinib-induced thrombocytopenia in treatment of patients with CML and so on.

OBJECTIVETo explore the differences of electroacupuncture (EA) on onset time and symptom improvement for treatment of different types of functional constipation.

METHODSThirty-eight cases of constipation were selected, including 9 cases of constipation-predominant irritable bowel syndrome (IBS-C), 10 cases of slow transit constipation (STC), 10 cases of pelvic floor dyssynergia (PFD) and 9 cases of inadequate defecatory propulsion (IDP). The electroacupuncture was applied at Tianshu (ST 25), Fujie (SP 14), Shenshu (BL 23), Dachangshu (BL 25) and so on in abdominal and lumbosacral area, 5 times per week, 10 times as a treatment course. The onset time, score of clinical symptoms of constipation and improvement of every symptom in each group were compared.

RESULTS(1) The onset time was (1.78 +/- 0.83) days in IBS-C type, (3.11 +/- 1.90) days in IDP type, (4.10 +/- 1.85) days in STC type and (4.30 +/- 2.00) days in PFD type, indicating statistical differences between IBS-C type and STC type, IBS-C type and PFD type (both P < 0.05). (2) Compared before the treatment, the total scores of symptoms on the onset day in each group were all improved (P < 0.05, P < 0.01), and score of IBS-C type was superior to the rest 3 types (P < 0.05, P < 0.01). (3) EA improved desire to defecate or frequency of defecation in each type (P < 0.05, P < 0.01), in which both were improved in STC type and PFD type, and the improvement of defecation frequency was more significant in STC type (P < 0.01). EA relieved unsmooth defecation or pendant-expansion feeling in each type (all P < 0.05), in which both were improved in IBS-C type (both P < 0.05). EA relieved abdominal distension and pain in IBS-C type, STC type and PFD type (all P < 0.05), while its effects were not obvious on defecation difficulty, defecation time and defecation texture (all P > 0.05).

CONCLUSIONThe electroacupuncture for treatment of 4 types of constipation is characterized by rapid onset; the improved symptoms are not identical in the electroacupuncture treatment plan for each type of defecation; the main improvement of symptoms are lied on desire to defecate and frequency of defecation, unsmooth defecation or pendant-expansion feeling and abdominal distension and pain. Meanwhile the improvements of defecation texture, defecation difficulty and defecation time were not signi-ficant.

OBJECTIVETo compare therapeutic effects of locking plates for the treatment of Neer 3-and 4-part proximal humerus fractures.

METHODSFrom January 2009 to June 2011, 64 patients with Neer 3-and 4-part proximal humerus fractures were treated with locked plate fixation. There were 39 patients in the 3-part group including 16 males and 23 females, with an average age of (55.12 +/- 12.52) years old; and 25 patients in the 4-part fractures group including 9 males and 16 females,with an average age of (57.92 +/- 13.14) years old. The American Shoulder and Elbow Surgeons score (ASES), visual analogue scale (VAS) and complications were documented for analysis before and after treatment.

RESULTSAll the patients had incision healing at the first stage. All the patients were followed up, and the duration ranged from 12 to 30 months, with a mean of 16.5 months. Comparably better shoulder function recovery was achieved in the 3-part fractures group with regard to the ASES (76.14 +/- 14.10 in the 3-part fractures group vs. 65.93 +/- 11.82 in the 4-part fractures group, P < 0.05). Moreover,a statistical difference (P < 0.05) was observed regarding the VAS pain score (2.12 +/- 1.63 in the 3-part fractures group vs. 3.90 +/- 2.21 in the 4-part fractures group). For the complications rate,no statistical difference was noted between 3-part fractures group and 4-part fractures group (20.51% vs. 36.00%).

CONCLUSIONThe clinical outcomes of the 3-part proximal humerus fractures is better than the 4-part fractures proximal humerus fractures treated with locking plate. Complex proximal humeral fractures treated with locking plates can be achieved a satisfactory outcome when attention is paid to anatomic reduction, stable fixation, proper screws and plate placement, and reasonable functional exercise postoperative.

Objective To study the change and the significance of T-lymphocyte immune function in peripheral blood in population living in arsenic-contaminated area. Methods Fifty-three cases of patients with arsenism symptoms were selected into experimental group, inhabitants who had no chronic arsenism symptoms into control group in the endemic area of Shuocheng District, Shuozhou City, Shanxi Province in 2006. Vein blood samples were taken and analyzed with SAP assay to measure the percentage of CD3+ ,CD4+ and CD8+ T-cells. Results It was found that the percentage of CD3+, CD4+, and CD4+/CD8+ [(41.89 ± 11.58)%, (25.60 ± 9.05)% and 1.02 ± 0.41] in the experimental group was lower than that in the control group [(68.38 ± 7.23)%, (39.17± 4.28)% ,1.69 ± 0.56, t = 13.61,18.72,14.79, all P < 0.05], while there was no statistical differences of CD8+ [(25.30 ± 6.85)%] compared to the control group[(23.54 ± 8.35)%,t = 3.07,P > 0.05]. The gender-related effect of arsenic on CD4+ and CD8+ was found by multiple linear step regression analysis(t = - 3.05, - 4.30, all P < 0.05). In case group, there were no statistical differences in CD3+, CD4+, CD8+ and CD4+/CD8+[(40.65±10.06)%, (24.48 ± 6.29)%, (24.52 ± 8.16)%,0.98 ± 0.25] between males and females [(43.07±12.96)%, (26.77±3.12)%, (26.50 ±9.32)%, 1.07 ±0.41, t = - 0.76,3.05,0.30,2.10, all P > 0.05]. Conclusions The immune function of T-lymphocytes of patients with chronic arsenism has been suppressed. It is of active significance to detect T-lymphocyte subpopulation in peripheral vein in patients with chronic arsenism aiming at estimating the function of cell immune and providing early diagnosis index.

Objective To investigate the correlation between genetic polymorphisms of glutathione S-transferases (GSTs) and ulcerative colitis (UC) in Hubei Han population. Methods Genetic polymorphisms of GSTM1 and GSTT1 of 270 patients with UC (UC group) who were admitted to the Zhongnan Hospital, People's Hospital of Wuhan University, Tongji Hospital and Union Hospital of Huazhong University of Science and Technology from August 2002 to December 2009 and 623 healthy people ( control group) were detected by restriction fragment length polymorphism-polymerase chain reaction. All UC patients were allocated to distal UC group (n= 229) and extensive UC group (n =41 ) according to the location of the lesions; and all UC patients were also allocated to mild-moderate group (n = 237) and severe group (n = 33 ). The genetic polymorphisms of GSTP1 of these patients and healthy people were detected by polymerase chain reaction. The genotypes of GSTM1, GSTT1 and GSTP1 were also detected. GSTM1 and GSTT1 containing small DNA segments ( 157 bp and 480 bp) were defined as GSTM1 (+) and GSTT1 (+), otherwise, GSTM(-) and GSTT1 (-), respectively. All data were analyzed by chisquare test. Results The frequencies of GSTM1(-), GSTT1(-) and GSTP1 (Val/Val) were 70.7% (191/270),64.8% (175/270) and 48.9% (132/270) in the UC group, and 41.7% (260/623), 47.2% ( 294/623 ) and 34.3% (214/623) in the control group, with a significant difference between the two groups (x2 = 63. 404,22. 320, 25. 384, P ＜0.05 ). The frequencies of GSTT1 (-) and GSTP1 (Val/Val) were 71.6% (164/229) and 57.6% (132/229) in the distal UC group, which were significantly higher than 31.7% (13/41) and 29.3%( 12/41 ) in the extensive UC group ( x2 = 24.528, 9.609, P ＜ 0.05 ). The frequencies of GSTM1 (-) were 65.1%(149/229) in the distal UC group and 56.1% (23/41) in the extensive UC group, with no significant difference between the two groups ( x2 = 1. 210, P ＞ 0.05 ). The frequencies of GSTT1 (-) and GSTP1 ( Val/Val ) were 71.6%(164/229), 31.7% ( 13/41 ) in the distal UC group and 57.6% ( 132/229), 29.3% ( 12/41 ) in the extensive UC group, with a significant difference between the two groups ( x2 = 24. 528, 9. 609, P ＜ 0. 05 ). There was no significant difference in the frequencies of GSTM1 (-), GSTT1 (-), GSTP1 (Val/Val) in the mild-moderate group and the severe group( x2 = 0. 623, 1. 884, 3. 403, P ＞ 0. 05 ). Conclusions Variant genotypes of GSTs are significantly correlated with UC in Hubei Han population. The severity of UC may not be correlated with variant genotypes of GSTs.

AIM:To investigate the dependence of the adrenoceptor regulation on oxidative stress in the rats with cardiac injury induced by high sympathetic activity .METHODS: Healthy SD rats were randomly divided into 7 groups:control, model, propranolol (Pro), prazosin (Praz), Pro+Praz, vitamin E (VE) and Pro+Praz+VE.The rats were intraperitoneally injected with norepinephrine ( NE) for continuous 16 d to reproduce cardiac injury , and treated with the respective drugs .During the experimental process , the body weight was recorded .At the end of the experiments , the following parameters were measured:the ventricular remodeling indexes ( cardiac index and hydroxyproline of the left ven-tricle), histopathologic examination , oxidative/antioxidative indexes [MDA, SOD, catalase (CAT), GSH-Px and total an-tioxidant capacity (T-AOC)], and energy metabolism (Na+-K+ATPase and Ca2+-Mg2+ATPase).RESULTS: The in-crease of body weight in model group was significantly slower than that in control group after 9 d of treatment (P<0.05). The cardiac index and left ventricular hypertrophy were significantly increased .Oxidation/antioxidation and energy metabo-lism were disturbed.In Pro, Praz, Pro+Praz and VE groups, the body weight, cardiac index, left ventricular fibrosis and oxidative/antioxidative dysfunction were ameliorated .Pro, Praz and Pro +Praz increased the activity of Na +-K+ATPase and Ca2+-Mg2+ATPase.Treatment with Pro+Praz showed the best result in all of the indexes (P<0.05).CONCLU-SION:The dependence of adrenoceptor regulation plays an important role in the formation of oxidative stress in the process of rat cardiac injury induced by high sympathetic activity .
