Objective:To compare the antihypertensive effects of tuina at Taichong (LR 3),Neiguan (PC 6) and Qiaogong (Extra) to screen the best tuina protocol for primary hypertension due to liver-fire flaming-up.Methods:A total of 102 patients with primary hypertension due to liver-fire flaming-up were randomly divided into a Taichong (LR 3) group,a Neiguan (PC 6) group and a Qiaogong (Extra) group according to the random number table,with 34 cases in each group.Patients in the three groups received 4-week tuina treatment with the corresponding acupoint respectively.The blood pressure was recorded by benchtop mercury sphygmomanometer before tuina,immediately after tuina treatment,30 min and 60 min after tuina treatment with the patient in a supine position in a quiet treatment room.The total effective rate was observed.Results:The systolic and diastolic blood pressures of the three groups all decreased after treatment (all P＜0.05).The decrease of systolic and diastolic blood pressure at different time points after treatment in the Qiaogong (Extra) group and the Taichong (LR 3) group were better than those in the Neiguan (PC 6) group (all P＜0.05).Qiaogong (Extra) group had the highest total effective rate though there was no statistical difference in the total effective rate among the three groups (P＞0.05).Conclusion:Treating primary hypertension due to liver-fire flaming-up with tuina at Taichong (LR 3),Neiguan (PC 6) and Qiaogong (Extra) can reduce systolic and diastolic blood pressure respectively,among which Qiaogong (Extra) has the highest total effective rate.

OBJECTIVETo explore the effects of stromal interaction molecule 1 (STIM1) on the expression of apoptosis-related proteins in prostate cancer PC-3 cells.

METHODSWe transfected the lentivirus vector STIM1-pGCSIL-GFP carrying STIM shRNA into human hormone-independent prostate cancer PC-3 cells, and 3 days later observed the transfection efficiency by fluorescence microscopy. At 7 days after transfection, we determined the expression of STIM1 in the PC-3 cells by RT-PCR and Western blot and those of apoptosis-related proteins Bcl-2, Bax, survivin and activated Caspase-3 by Western blot.

RESULTSAt 3 days, inverted microscopy revealed a transfection efficiency of > 80%. At 7 days, the STIM1 expression was significantly inhibited at both mRNA and protein levels. The Bcl-2/Bax rate was remarkably decreased as compared with that of the control group (0. 31 vs 1.24 ) , and the survivin expression was markedly reduced, 0. 14 times that of the relative expression in the control. However, the Caspase-3 cleavage was significantly activated, 1.52 times that of the control (P <0.05).

CONCLUSIONSTIM1 can be regarded as an oncogene in prostate cancer PC-3 cells. Inhibition of its expression can induce PC-3 cell apoptosis by reducing the Bcl-2/Bax rate, decreasing the survivin expression, and activating the Caspase-3 pathway.

OBJECTIVETo observe the efficacy and safety of modified Shengma Biejia Decoction (MSBD) combined with CAG program in treating elderly acute myeloid leukemia (AML) patients with yin deficiency toxin stasis syndrome (YDTSS).

METHODSTotally 46 elderly AML patients were assigned to the treatment group (24 cases; treated with MSBD + CAG) and the control group (22 cases; treated with CAG + placebos of Chinese medicine) according to random digit table. The therapeutic course of CM placebo or MSBD was 21 days. The clinical efficacy and adverse reactions were observed. Meanwhile, physical state (ECOG Score), transfusion dependency, and TCM syndrome score were compared before and after treatment.

RESULTS(1) The complete remission rate was 54% (13/24) and the objective response rate (ORR) was 71% (17/24) in the treatment group, obviously higher than those of the control group [36% (8/22); 54% (13/24)], with statistical difference (P = 0.036, 0.042). When comparing the efficacy based on risk level, the moderate and poor ORR was 71% (10/14) and 67% (6/9) in the treatment group, and 57% (8/14) and 33% (2/6) in the control group, with statistical difference between the two groups (P = 0.048; P = 0.010). (2) Compared with before treatment in the same group, the ECOG score significantly decreased, the average infusion time of red cells and platelets were markedly prolonged in the treatment group after treatment (P < 0.05). ECOG score, the average infusion time of red cells and platelets were significantly better in the treatment group than in the control group after treatment (P < 0.05). (3) Compared with before treatment in the same group, scores of fever, hemorrhage, and bone pain were markedly reduced in the control group (P < 0.05); scores of fever, fatigue, hemorrhage, dry mouth, and bone pain were markedly reduced in the treatment group (P < 0.05). Better effect in relief of fever, fatigue, hemorrhage, dry mouth, and so on was obtained in the treatment group than in the control group (P < 0.05). (4) In aspect of hematotoxicity, the incidence of neutropenia, anemia, thrombocytopenia was obviously lower in the treatment group than in the control group [29.2% (7/24) vs 54.5% (12/22); 16.7% (4/ 24) vs 45.5% (10/22); 33.3% (8/24) vs 63.6% (14/22); P < 0.05]. The incidence of fatigue and anorexia was obviously lower in the treatment group than in the control group [37.5% (9/24) vs 63.6% (14/22), 37.5% (9/24) vs 81.8% (18/22); P < 0.05].

CONCLUSIONMSBD combined with CAG program in treating elderly AML patients with YDTSS, with efficacy enhancing toxicity reducing effect, had distinct advantages in improving physical condition and clinical symptoms, and reducing transfusion dependency.

Objective To observe the effect of human immunoglobulin on elderly head and facial post herpetic neuralgia (PHN) and peripheral blood TNF-α.Methods One hundred and twenty-two inpatients with PHN aged ≥65 years old were selected and divided into the observation group (52 cases) and control group (70 cases) by the systematic sampling method.The control group was given the early conventional combined therapy,while on this basis the observation group was intravenously dripped by human immunoglobulin.The incidence rate of PHN and pain visual analog scale(VAS) score at 1,2,3 months after recovery discharge from hospital were recorded in the two groups.Other 20 healthy elderly people were selected as the healthy control group.The TNF-α level was determined in the two patients groups before and after treatment and in the healthy control group.Results The PHN occurrence rate at 1,2,3 months after discharge in the observation group was significantly lower than that in the control group(P＜0.05);the VAS score after treatment and at 1,2,3 months after discharge in the observation group was significantly lower than that in the control group (P＜0.05);serum TNF-α level after treatment in the observation group was significantly lower than that in the control group (P＜0.01),moreover which was close to the level in the healthy control group(P＞0.5).Conclusion Human immunoglobulin can reduce the PHN occurrence in the old people with head and facial herpes zoster and reduce the peripheral blood TNF-α level.

BACKGROUND: Preliminary study has prepared three-dimensional printing β-tricalcium phosphate scaffold loaded with icariin. OBJECTIVE: To investigate the role of three-dimensional printing β-tricalcium phosphate scaffold loaded with icariin in the repair of rabbit models of osteonecrosis of the femoral head. METHODS: New Zealand white rabbits (provided by Qinglongshan Laboratory Animal Center of Nanjing) were selected to establish the steroid-induced osteonecrosis of the femoral head. The 27 model rabbits underwent core decompression and debridement, were randomly divided into three groups, and then implanted with autologous bone, β-tricalcium phosphate scaffold, three-dimensional printing β-tricalcium phosphate scaffold loaded with icariin (composite scaffold group) , respectively. The micro-CT scanning and pathological observation were performed at 4, 8, and 12 weeks after implantation. RESULTS AND CONCLUSION: (1) Micro-CT showed that at 4 weeks after implantation, trabecular bone was observed around and in implants in each group. In the autologous bone group, there were a large number of trabecular bones in the grafting area at 8 weeks, and the trabecular bone structure was dense at 12 weeks after implantation. In the tricalcium phosphate and composite scaffold groups, the scaffolds were well integrated with the bone interface. At 4 weeks after implantation, there was a certain amount of trabecular bone surrounding the scaffold, and trabecular grew into the scaffold until 8 weeks in the composite scaffold group. At 4 weeks after implantation, few thin trabecular bone was visible, and extensive trabecular bone formation was observed around the scaffold at 8 weeks in the tricalcium phosphate group. (2) Hematoxylin-eosin staining results showed that there were many mature osteoblasts, and few cartilage matrix, newly born bones integrated well to the implants at 12 weeks in the autologous bone and tricalcium phosphate groups. In the composite scaffold group, there were many cartilage matrixes, and newly born bones integrated poorly to the implants. (3) Masson staining showed that at 12 weeks after implantation, the osteogenic capacity in the composite scaffold group was lower than that in the autologous bone group (P < 0.05) , but higher than that in the tricalcium phosphate group (P < 0.05) . (4) TRAP staining results at 12 weeks after implantation revealed that the amount of osteoclast in composite scaffold group was less than that in the tricalcium phosphate group (P < 0.05) , and was not significantly different from the autologous bone group (P> 0.05) . (5) Immunohistochemical staining at 12 weeks after implantation revealed that the positive rate of vascular endothelial growth factor in the composite scaffold group was higher than that in the tricalcium phosphate group (P < 0.05) , and lower than that in the autologous bone group (P < 0.05) . (6) In summary, three-dimensional printing β-tricalcium phosphate scaffold loaded with icariin implanted into the rabbit model of osteonecrosis of the femoral head can promote the proliferation and differentiation of osteoblasts, inhibit the viability of osteoclasts, promote the angiogenesis, and contribute to the repair of osteonecrosis of the femoral head in rabbits.

OBJECTIVETo explore the expression of gut-enriched Kruppel-like factor 4(KLF4) in gastric cancer, and its association with prognosis.

METHODSSurgical specimens were collected from 264 patients undergoing radical surgery between 2004 and 2009 in the Affiliated Qianfoshan Hospital, Shandong University. KLF4 mRNA level of specimens was detected by real-time PCR. KLF4 protein expression was measured by immunohistochemistry on tissue microarray, which contained primary gastric cancer, corresponding para-cancerous tissue, and paired lymph node metastases.

RESULTSReal-time PCR revealed that mRNA level of KLF4 was down-regulated in gastric cancer compared with paired normal gastric mucosa. Immunohistochemistry on tissue microarray showed gastric cancer tissues had significantly lower KLF4 levels compared with paired normal gastric tissues. By univariate and multivariate analysis, KLF4 was a significant predictor of survival and recurrence.

CONCLUSIONKLF4 expression is significantly down-regulated in gastric cancer, and is an independent predictor of survival and recurrence.

OBJECTIVETo investigate the clinicopathological characteristics, diagnosis, treatment and prognostic factors of gastric gastrointestinal stromal tumors(GIST) in the stomach.

METHODSThe clinicopathological data of 132 patients with gastric GIST between January 1998 and December 2008 were analyzed retrospectively, and the prognostic factors were evaluated.

RESULTSTumor locations were the cardia or fundus (50, 37.9%), the stomach body (62, 47%),the antrum (13, 9.8%), and two regions were found in 6 cases (4.5%), three regions in 1 cases (0.8%). Tumor size ranged from 1.0 to 27.0 cm with an average of 9.4 cm. All the patients underwent complete tumor resection, including multi-organ resection in 41 cases. Thirty-four cases underwent lymph node dissection. All the lymph nodes were negative. The positive rate was 93.2% (23/132) for CD 117 and 82.6% (109/132) for CD34. The 1-,3- and 5-year survival rates of the 118 cases with follow up were 94.7%, 80.2%, and 56.6%, respectively. Univariate analysis revealed that the differences in Fletcher classification, tumor size, infiltration to surrounding tissue, preoperative metastasis, and adjuvant postoperative therapy with imatinib were related to the survival rates. Multivariate analysis demonstrated that Fletcher classification, preoperative metastasis and adjuvant postoperative therapy with imatinib were independent poor prognostic factors for survival.

CONCLUSIONSPreoperative metastasis is an independent factor predicting poor prognosis of gastric GIST. Fletcher classification can be used to evaluate the biological behaviors and prognosis, while surgery is the main therapy and targeted therapy can improve survival of gastric GIST.
