AIM: To explore the mechanism of myocardium protection after ischemia/reperfusion (I/R) injury by preconditioning with ischemia in human. METHODS: Thirty - six patients underwent valve replacement were divided into ischemic preconditioning group (IP group, 20 cases) and non -ischemic preconditioning group (control group, 16 cases) according to whether they were given single cycle reperfusion before cardioplegia or not. Serum levels of interleukin -8 and 10 were measured with ELISA. Expressions of myocardial Bel -2 and caspase -3 were analyzed. RESULTS: The inflammatory factors IL - 8 and IL - 10 increased to the highest level in serum at 6 h after declamping and recovered to normal level on 5 d after declamping. On 6 h, 1 d and 2 d after declamping, serum level of IL -8 was significantly lower in IP group than that in control group ( P < 0.05 ) , but serum level of IL -10 was higher in IP group (P < 0.05 ). Expression of myocardial Bel - 2 and caspase - 3 increased in both groups after reperfusion, and Bel - 2 was lower in the control group than that in IP group while the level of caspase - 3 was higher (P < 0.05). Expression of myocardial Bel - 2 had positive correlation with IL - 10 and negative correlation with IL - 8.CONCLUSION: Ischemic preconditioning has the effect of protection of human myocardial cells after ischemia/reperfusion injury through decreasing systemic inflammatory response following ischemia reperfusion injury.

OBJECTIVETo explore effective approaches of treating elderly patients with distal tibiofibular fractures.

METHODSFrom August 2008 to October 2012,175 elderly patients with distal tibiofibular fractures were treated with locking compression plate (LCP) through anterior tibial. There were 112 males and 63 females with an average of 71.3 (ranged 60 to 83) years old. Of them,89 cases were treated by anterior tibial tension reduced incision with LCP,including 62 males and 27 females with a mean age of (71.8 +/- 6.4) years old. Eighty-six patients were treated by distal tibial incision with LCP,including 58 males and 28 females with a mean age of (70.3 +/- 6.7) years old. Swelling time, operation time, intraoperative blood loss, hospital stay, healing time, complications and AOFAS scores were compared between two groups after operation.

RESULTSSwelling time in anterior tension reduced incision with LCP and distal tibial incision with LCP was (5.6 +/- 1.3) and (9.7 +/- 2.1) days, healing time was (4.2 +/- 1.4) and (5.4 +/- 1.9) months,and complications were found 3 in tension reduced incision and 10 in distak tibial incision respectively;and all data shown statistically significant differences between two groups (P < 0.05). At 12 months after operation,AOFAS score was 89.0 +/- 9.7, 87.9 +/- 9.4; and there was no statistically significant difference between two groups (P > 0.05).

CONCLUSIONTension reduced incision through anterior tibial combined with locking compression plate fixation in treating elderly patients with distal tibiofibular fractures can provide good clinical effects with quick fracture healing and low complications.

OBJECTIVETo observe the regulatory effects of electroacupuncture with different acupoints combinations on blood lipid and atherosclerosis index (AI) in rats with hyperlipemia, so as to make a preliminary screening for the optimal acupoints combination for hyperlipemia.

METHODSOne hundred and five clean-grade SD male rats were randomly divided into 9 groups, including a normal group, a model group, a Quchi group, a Zhongwan group, a Fenglong group, a Quchi+Zhongwan group, a Quchi+Fenglong group, a Zhongwan+Fenglong group and a Quchi+Zhongwan+Fenglong group (three acupoints group), 17 rats in the normal group and 11 rats in the rest groups. The normal group was fed with normal diet, while the rest groups were fed with high-fat diet for 3 weeks to prepare the hyperlipemia model. All the rats were given unlimited water. After the establishment of model, the normal group was fed freely without any treatment; the model group was bundled and immobilized everyday; the rest groups were bundled, immobilized and treated with electroacupuncture at corresponding acupoints with disperse-dense wave, 20 min per time, once a day. After 4 weeks, the blood examples were collected from abdominal aorta to measure the total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL-C) and low-density lipoprotein (LDL-C), and analyzed the AI in each group.

RESULTSAfter the treatment, TC, TG, HDL-C, LDL-C and AI in each acupuncture group were all lower than those in the model group (P<0.05, P<0.01). Compared with single acupoint group and the Quchi+Zhongwan group, the content of TC in the three acupoints group was lower (P<0.01). The differences of content of TG among each acupuncture group were not significant (all P>0.05). Compared with the rest 6 acupuncture groups, the content of HDL-C and AI in the three acupoints group were significantly different (all P<0.05). The content of LDL-C in the three acupoints group was decreased as compared with the Quchi group and the Zhong-wan group.

CONCLUSIONThe electroacupuncture at "Quchi" (LI 11), "Zhongwan" (CV 12) and "Fenglong" (ST 40) has more advantages on regulating the content of HDL-C and LDL-C as well as improving AI in hyperlipemia rats, and it has superior effects on blood lipid metabolism.

In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.

BACKGROUND:The incidence rate of peripheral T cel lymphoma is high in Asia, and peripheral T cel lymphoma is aggressive with generaly poor prognosis. However, there is no standard treatment strategy. OBJECTIVE:To retrospectively analyze the therapeutic effect of autologous hematopoietic stem cel transplantation on peripheral T cel lymphoma as wel as relevant toxic and side effects. METHODS:A retrospective review was conducted in 35 patients with peripheral T cel lymphoma who underwent autologous hematopoietic stem cel transplantation from March 2003 to April 2014, including 22 cases of extranodal NK/T-cel lymphoma (nasal type), 1 case of angioimmunoblastic T-cel lymphoma, 8 cases of peripheral T cel lymphoma (non-specific), 3 cases of ALK-positive anaplastic large cel lymphoma, and 1 case of ALK-negative anaplastic large cel lymphoma. Al of 35 patients were classified pathologicaly according to WHO pathological type in 2001 and 2008, and received the high-dose chemotherapy with vincristine, cytarabine, etoposide, mitoxantrone, semustine, cyclophosphamide, and total body irradiation. RESULTS AND CONCLUSION: After a median folow-up of 54 (9-120) months, the probabilities of overal survival and disease-free survival after transplantation were 80% (n=28) and 71% (n=25), respectively. Eight cases (23%) relapsed after transplantation, seven of which died. It was safe with mild and moderate transplantation related side-effects on opportunistic infections, oral cavity mucosa and bladder responses and so on, and there were no severe, life-threatening late complications. Autologous hematopoietic stem cel transplantation may be an effective and safe treatment for peripheral T cel lymphoma, and there is a better benefit in peripheral T cel lymphoma patients with first complete remission.

Objective To investigate the curative effect of allogeneic hematopoietic stem cell transplantation (allo-HSCT) and the method of the pretreatment choice on myelodysplastic syndrome (MDS).Methods 13 cases who were undergoing allo-HSCT including 10 HLA-matched, 2 HLA partially matched,and one umbilical cord blood transplanted patients were enrolled in this study. The infusion number of MNC and CD+34 cells is 6.92 (2.65-21.33)×108/kg and 4.47 (1.49-10.22) ×106/kg, respectively. Of the 13 cases,5 adopted TBI, fludarabine(Flud), and cyclophosphamide(Cy) pretreatment, 3 chose BU/Cy pretreatment, and 3 chose TBI and Cy pretreatment, 2 chose Ara-C+BU+Cy+VM26 pretreatment. In order to prevent GVHD, 2cases of HLA partially matched were treated with ATG, cyclosporin A (CsA), MTX and MMF aftertransplantation, while the others were treated with CsA and MTX only. Results 9 out of 13 cases achieved hematopoietic reconstruction completely. 4 died of complications. Conclusion The allogeneic hematopoietic stem cell transplantation is an efficient regimen to cure MDS. The pretreatment should adopt the individuation.

Objective To study the N terminal pro brain natriuretic peptide (NT-proBNP)in serum of hypertension patients. Methods 152 patients with hypertension were included in this study.According to the different degree and development of hypertension,152 patients were divided into three different grade group of hypertension:first grade of hypertension group (30 patients),second grade of hypertension group (36 patients)and third grade of hypertension group (86 patients).And the 86 patients were divided into hypertension group (40 patients)and hypertension with diabetes group (46 patients)re-spectively,comparaed with the level of NT-proBNP in serum of different hypertension grade groups.Results The levels of the NT-proBNP in serum were 68±44,122±31 and 834±309 pg/ml of first grade of hypertension group,second grade of hypertension group and third grade of hypertension group,respectively.The level of the NT-proBNP was gradually increased with grade of hypertension (t=2.455,3.561,P<0.01).The level of the NT-proBNP (1 178±864 pg/ml)of hypertension with diabetes group was significantly higher than hypertension group (599±411 pg/ml)(t=3.785,P<0.01).Conclusion The level of NT-proBNP can obj ectively reflect the grade of the disease in patients with hypertension.it is a certain signifi-cance guiding for monitoring the clinical treatment of the disease.

OBJECTIVE: To explore the curative effect of nasal type extranodal NK/T-cell lymphoma by sequential chemotherapy combined radiotherapy compared with chemtherapy. METHOD: Fifty-seven cases of nasal type extranodal NK/T-cell lymphoma confirmed by pathological morphology and immuno-histochemistry were divided into chemotherapy combined radiotherapy group (34 cases) or chemotherapy group (23 cases). Twenty-three patients in the chemotherapy group alternately applied CHOP, VDLP and MEOP regimen after each two treatments into the clinical observation; Chemotherapy combined radiotherapy group of 34 patients, in addition to the above chemotherapy, applied three-dimensional conformal radiation therapy of the primary site by linear accelerators. Then all of patients were ceased treatment and followed up 3-5 years. RESULT: (1) After treatment, effective rate of two groups was 91.2% and 87.0%, there was no obvious difference (P > 0.05); After follow up about 1 year, effective rate of two groups was 76.5% and 73.9%, there was no obvious difference (P > 0.05); (3) After follow up about 3 years and 5 years, disease free survival (DFS) of two groups was 61.3%, 47.6% and 43.5%, 21.4%, there was obvious difference (P < 0.05). (4) Long-term survival is closely related to treatment mode. (5) B symptoms, advanced (III, IV) stage, the International Prognostic Index (IPI), KPS scores were correlated with prognosis, and were independent prognostic factors. CONCLUSION Treatment with chemotherapy and radiotherapy for nasal type extranodal NK/T-cell lymphoma had obvious curative effect and may improve long-term survival efficiently compared with chemotherapy alone.
