【Objective】To observe the efficacy and side effects of hematopietic stem cell transplantation with combination of umbilical cord blood(UCB) and neonatal peripheral blood(NPB) in the treatment of β-thalassemia major.【Methods】28 mL NPB was drawn from a HLA identical neonate within 5 hours after his birth to complement stem cell of the UCB he donated for transplantation to his sibling with β-thalassemia major.Various items of hematopoiesis reconstruction were detected in UCB and NPB respectively.After conditioning with chemotherapy by using busulfan 20 mg/kg,cyclophosphamide 200 mg/kg,melphalan 90 mg/m2 and antithymocyte globulin(ATG) 90 mg/kg,the patient received the 53 mL UCB and 28 mL NPB,achieving 5.7×107/kg nucleated cells(NC),93×105/kg CFU-GM and 3.1×105/kg CD34+CD38- cells from his HLA-identical sibling.【Results】Absolute nucleated cell(ANC) reached 0.5×109/L on 14th day post transplant,and platelets reached 20×109/L on 34th day after transplant.The heterozygosity of β-654 mutation point was detected by the PCR-RDB.The sexual chromosome changed from XX pretransplant to XY posttransplant.The patient was free red blood cell transfusion from 14th day post transplant.Her hemoglobin rose progressively from 86 g/L to 110 g/L.The patient survived for 197 days free from disease after transplantation.Following up for 9 months, the donor grew and developed normally.【Conclusion】The NPB contains a lot of stem cells.The transplantation with combination of suitable NPB and UCB is an effective tactics when the UCB cells are deficient.

OBJECTIVETo study the impact of IFN-gamma on liver fibrosis and its possible mechanism. Thirty healthy male SD rats were randomly divided into two groups: fibrosis model group, IFN-gamma treatment group. Experimental liver fibrosis was induced by subcutaneous injection of CCl4. After 12-week-treatment, serum hyalurnic acid and TGF-beta1 was examined, histopathological changes and degrees of fibrosis were observed by optical microscopy. Meanwhile, the expression of TGF-beta1, TbetaR- I and Smad2/3 proteins was detected by immunohistochemistry and quantified by using computerized image analysis.

RESULTS(1) Pathological observation of hepatic specimens: histological examination showed that there were significant difference between normal group and fibrosis model group by comparing with the degrees of inflammation and fibrosis (P < 0.05). And the difference between fibrosis model group and IFN-gamma treatment group was significant (P < 0.05). (2) Changes of the hepatic fibrosis index (serum HA and TGF-beta1): the levels of serum HA, TGF-beta1 in fibrosis model group were higher than IFN-gamma treatment groups (P < 0.05). (3) Changes of gene protein levels about TGF-beta1/Smad: the expressions of TGF-beta1, TbetaR- I and Smad2/3 in rat hepatic tissue were detected with immunohistochemistry techniques. The expressions of the three items in model group were higher than normal group (P < 0.01). The difference between model group and IFN-gamma treatment group was significant (P < 0.05);

CONCLUSIONIFN-gamma treatment group had significant results on treating experimental hepatic fibrosis. By the way of inhibiting expressions of TGF-beta1, TbetaR- I, Smad2/3, IFN-gamma treatment group exerted its anti-fibrosis effect.

OBJECTIVETo verify the safety of penetrating acupuncture at the head points for cerebral hemorrhage at the acute stage.

METHODSSixty cases of cerebral hemorrhage at the acute stage were selected and randomized into a western medication group and a head-point group, 30 cases in each one. In the western medication group, the anti-cranial pressure and anti-blood pressure program was administered with the conventional intravenous infusion of Sodium Nitroprusside, Mannite, etc. In the head-point group, on the basis of the treatment as the western medication group, the penetrating acupuncture at the head points was supplemented. For consciousness disturbance, Taiyang (EX-HN 5), Benshen (GB 13) and penetrating needling from Shenting (GV 24) to Shangxing (GV 23) were selected. For headache, the penetrating needling was adopted from Shangxing (GV 23) to Yintang (EX-HN 3) and from Fengchi (GB 20) to Fengchi (GB 20). For disturbance of urination and defecation, the penetrating needling was adopted from Baihui (GV 20) to Sishencong (EX-HN 1). For aphasia, the penetrating needling was adopted from Fengfu (GV 16) to Yamen (GV 15), etc. For facial paralysis, the penetrating needling from Dicang (ST 4) to Jiache (ST 6) and Xiaguan (ST 7) were selected. For paralysis, the penetrating needling was adopted from Baihui (GV 20) to Taiyang (EX-HN 5), etc. Before and after treatment, the changes in cerebral hemorrhagic volume, the results of blood, urine and stool routine examination, the situations of the life indices such as heart, liver and kidney functions, blood pressure, respiration and heart rate were observed, as well as the impacts on ECG.

RESULTSThe cranial CT sania cn indicated that the rate of the basic and significant absorption of hematoma was 80.0% (24/30) in the head-point group, which was superior to 56.7% (17/30) in the western medication group (P < 0.05). Before and after treatment, the results of blood, urine and stool routine examination and the life indices such as blood pressure, respiration and heart rate were all in the normal scope for the patients in the head-point group (all P > 0.05). There were no any abnormal changes in liver and kidney functions. In the head-point group, the abnormality rate of ECG was lower obviously than that in the western medication group [16.7% (5/30) vs 43.3% (13/30), P < 0.05].

CONCLUSIONThe penetrating acupuncture at the head points is safe in the treatment of cerebral hemorrhage at the acute stage.

OBJECTIVETo study the effect of pGCsi-H1-APRIL on the growth of human colorectal cancer cells in transplated tumor in nude mice and to improve the effect of APRIL on proliferation and apoptosis of colorectal cancer (CRC).

METHODSHuman CRC model was established in nude mice, and the nude mice were treated with APRIL siRNA twice per week for 2 weeks. APRIL mRNA expression was surveyed by PCR and APRIL protein expression was detected by immunohistochemistry. The expression of PCNA protein was detected by ELISA. The expression of bcl-2 and bcl-xl was assessed by immunohistochemical staining, and TUNEL staining was used to detect apoptosis.

RESULTSThe expression of APRIL mRNA in the APRIL siRNA group was (0.13 ± 0.05) × 10(-3), significantly lower than that in the vector group (0.95 ± 0.04) × 10(-3) and the PBS group (0.96 ± 0.05) × 10(-3). The expression of APRIL protein in the APRIL siRNA group was (87.5 ± 5.0)% lower than that in the vector and PBS groups (P < 0.05). APRIL siRNA significantly suppressed the growth of SW480 tumor: the IR (inhibitory rate) of APRIL siRNA group was (60.7 ± 1.5)% (P < 0.05). The expression of PCNA in APRIL siRNA group was (176.8 ± 18.1) ng/ml, was (56.5 ± 2.0)% lower than that of PBS group (328.4 ± 22.8) ng/ml. Furthermore, the expressions of anti-apoptosis proteins bcl-2 and bcl-xl of APRIL siRNA group were (82.6 ± 4.5)% and (79.2 ± 3.5)% lower than those of the PBS group. The apoptotic rate of the APRIL siRNA group was 40.1% ± 2.5%, significantly higher than that in the vector group (2.5 ± 0.1)% and PBS group (2.5 ± 0.2)% (P < 0.05).

CONCLUSIONAPRIL siRNA may significantly suppress the growth and promote apoptosis in transplanted tumor of human colorectal cancer in nude mice. APRIL may become a candidate gene of gene therapy of human colorectal cancer.

OBJECTIVETo study the influence of anastomoses sequence on the hemodynamics in off-pump coronary artery bypass grafting (CABG), and to investigate the strategy to stabilize the hemodynamics.

METHODSFrom March 2005 to March 2007, 67 patients with serious triple-vessel coronary artery lesions (male 45, female 22) with a age range from 44 to 81-years-old were enrolled for off-pump CABG. All the patients underwent left internal mammary artery-left anterior descending branch (LIMA-LAD) anastomose firstly, followed by the foreword anastomose of the other two vessels. According to the anastomose sequence of posterior descending branch (PDA) and obtuse marginal branch (OM), the patients were divided into three groups. Group I (n = 22) did the sequence of PDA-OM-aortic root (Ao). Group II (n = 14) did the sequence of Ao-PDA-OM. Group III (n = 31) did the sequence of Ao-OM-PDA. The hemodynamics markers, including heart rate (HR), central venous pressure (CVP), mean artery pressure (MAP), cardiac index (CI), left ventricular-stroke work index (LVSWI) and right ventricular stroke work index (RVSWI), were analyzed before LIMA-LAD anastomose to serve as baseline. And these markers were re-measured at LIMA-LAD anastomose, immediately after LIMA-LAD anastomose, at PDA anastomose and at OM anastomose.

RESULTSAll the patients survived after off-pump CABG. Compared with the baseline, there were no significant hemodynamic changes when doing LIMA-LAD anastomose. When the anastomose finished, the hemodynamic indices improved significantly. When performing OM anastomose, HR and CVP increased significantly, and MAP, CI, LVSWI and RVSWI decreased remarkably in group I and group III, while there were no significant changes of MAP, CI and RVSWI in group II . When performing PDA anastomose, HR and CVP increased significantly, and MAP, CI, LVSWI and RVSWI decreased remarkably in group I and group II, while there were no significant hemodynamic changes in group III except HR.

CONCLUSIONProximal anastomose first when performing off-pump CABG, followed by distal anastomoses of target vessels is beneficial to those who have hard exposure and difficult anastomose of OM and PDA.

OBJECTTo explore the better treatment of lumbar intervertebral disc herniation.

METHODSOne hundred and thirty-two cases of lumbar intervertebral disc herniation were randomly divided into an observation group and a control group, sixty-six cases in each group. In observation group, Baihui (GV 20) penetrating to Taiyang (EX-HN 5), Jiaji (EX-B 2), Huantiao (GB 30) and Chengfu (BL 36) etc. on affect side were applied; in control group, Shenshu (BL 23), Dachangshu (BL 25), Huantiao (GB 30) and Chengfu (BL 36) etc. on affect side were applied. Once a day, 6 treatments made one session and one day break between courses. The curative effects after 4 and 8 courses and the recurrence rate that 6 months after treatment were observed; the pain scale evaluated by Visual Analogue Scale (VAS) and the Oswestry Disability Index (ODI) were observed.

RESULTSThe cured rate and total effective rate were 44.3% (27/61) and 100.0% (61/61) in observation group, 26.7% (16/60) and 93.3% (56/60) in control group after 4 courses; there were significant differences between two groups (all P < 0.05). After 8 courses, the cured rate and total effective rate were no significant differences between two groups (all P > 0.05). In observation group, the recurrence rate was 9.4% (5/53) 6 months after treatment, which was lower than that (24.1%,13/54) in control group (P < 0.05). The VAS and ODI scale were significantly reduced (all P < 0.05) after treatment, and which in observation group were inferior to those in control group (all P < 0.01).

CONCLUSIONThe lumbar intervertebral disc herniation treated with puncture by opening meridian and consolidating origin is rapidly effected with low recurrence rate.
